<Embodiment 1>
Based on FIG. 1 thru | or FIG. 4, the solar power generation unit manufacturing method which concerns on Embodiment 1 of this invention is demonstrated.

  FIG. 1 shows a pin joining step for joining positioning pins and a protective plate positioning step for fitting the positioning pins to the pin fitting portion for positioning in the photovoltaic power generation unit manufacturing method according to Embodiment 1 of the present invention. It is a disassembled perspective view to explain. FIG. 2 is a cross-sectional view taken along a plane passing through the center of the positioning pin after the protective plate alignment step according to Embodiment 1 of the present invention, and (A) is a cross-sectional view in the short direction of the long frame. (B) is a cross-sectional view in the longitudinal direction of the long frame and shows a state where the side portion is viewed from the inside of the long frame, and (C) is an enlarged cross-sectional view of the positioning pin. FIG. 3 is a plan view showing details of a planar positional relationship among the translucent protective plate, the condenser lens, and the positioning pins shown in FIG.

  In the present embodiment, a long frame 44 having side portions 44s and a bottom portion 44b, a solar cell 10 (see FIG. 4) disposed corresponding to the bottom portion 44b, and sunlight by collecting sunlight. A condensing type provided with a condensing lens 42 for irradiating the solar cell 10 from the irradiation hole 45 and having a translucent protective plate 41 attached to an edge 44f of the top surface of the side portion 44s (an edge 44f of the side portion 44s). The present invention relates to a solar power generation unit manufacturing method for manufacturing the solar power generation unit 40.

  The translucent protective plate 41 of the concentrating solar power generation unit 40 is fixed and held on the rim 44f (the top surface of the long frame 44) via the packing 44fp. The translucent protective plate 41 is provided in advance with a condenser lens 42 that is aligned with the arrangement of the solar cells 10, and the translucent protective plate 41 with respect to the solar cells 10 that are arranged corresponding to the bottom 44 b. It is necessary to fix the condensing lens 42 to the edge 44f in a state where the condenser lens 42 is accurately aligned.

  That is, in the photovoltaic power generation unit manufacturing method according to the present embodiment, the pin joining step for joining the positioning pin 41p to the edge 41f of the translucent protective plate 41 corresponding to the center of the condenser lens 42, and the edge 41f The joined positioning pin 41p is fitted to a pin fitting portion 44p provided on the edge 44f of the top surface of the side portion 44s, so that the translucent protective plate 41 (edge 41f) is edged 44f of the top surface of the side portion 44s. A protective plate aligning step for aligning with the protective plate. The condensing lens 42 and the positioning pin 41p are arranged on the same surface of the translucent protective plate 41 (a surface facing the inner side of the long frame 44).

  With this configuration, since the translucent protective plate 41 can be aligned with high accuracy by a simple method with respect to the long frame 44, the condensing lens 42 and the solar cell 10 can be aligned with high accuracy and It becomes possible to irradiate the solar cell 10 with the sunlight condensed by the lens 42 accurately. Therefore, it is possible to manufacture the solar power generation unit 40 having excellent light collecting properties. Moreover, after installing the condensing system (solar power generation unit 40), it is easy to exchange lenses at the installation location.

  The edge 41f is formed around the translucent protective plate 41 (the outer periphery of the condenser lens 42) so as to correspond to the edge 44f. By aligning and bringing the edge 41f and the edge 44f into contact with each other, The translucent protective plate 41 is configured to be fixed and held on the edge 44f (side portion 44s, long frame 44).

  The alignment between the translucent protective plate 41 and the condensing lens 42 (for example, ten in the lens group unit area LA) is aligned with the solar cell 10 corresponding to the ten condensing lenses 42. It is possible to carry out directly by joining the condensing lens 42 and the translucent protective plate 41 in a state matched with the arrangement of the above. Alternatively, the translucent protective plate 41 and the condensing lens 42 can be integrally formed. Therefore, alignment between the translucent protective plate 41 and the condenser lens 42 is performed with high accuracy.

  However, alignment of the edge 41f of the translucent protective plate 41 and the edge 44f of the long frame 44 is not easy. In other words, there is a problem in accuracy in aligning the outer edge portion of the translucent protective plate 41 whose outer shape becomes larger because a large number of condenser lenses 42 are held. In addition, the alignment of the translucent protective plate 41 with respect to the solar cell 10 (sunlight irradiation hole 45) corresponding to the bottom 44b means that the side portion 44s exists between them and the distance from the solar cell 10 is increased. This is difficult because the viewing positions do not match.

  Therefore, in the present embodiment, as the positioning structure of the translucent protective plate 41, the center of the condensing lens 42c is formed on the surface (condensing lens forming surface) facing the rim 44f (the top surface of the side portion 44s) of the rim 41f.

FIG. Since the centers of the condensing lenses 42c arranged in two rows in the short direction of the translucent protective plate 41 are used as a reference, the positioning of the two positioning pins 41p arranged in the longitudinal direction of the translucent protective plate 41 is determined. Can be reliably performed with high accuracy.

  As described above, the condensing lenses 42 are preferably provided in at least two rows on the translucent protective plate 41.

When the elongated frame 44 is formed, the pin fitting portion 44p can be arranged and formed with high accuracy in alignment with the position of the solar cell 10 (sunlight irradiation hole 45).

  Therefore, by positioning and fitting the positioning pin 41p to the opposing pin fitting portion 44p, the translucent protective plate 41 (condensing lens 42) is trimmed to the edge 44f (side portion 44s, long frame 44). It becomes possible to align with high accuracy, and as a result, the translucent protective plate 41 (condensing lens 42) can be aligned with the solar cell 10 with high accuracy.

  Since the positioning pin 41p is positioned with reference to the center of the condensing lens 42c formed in advance on the translucent protective plate 41 corresponding to the solar cell 10, the translucency with respect to the solar cell 10 (long frame 44) is transmitted. It is possible to reliably improve the alignment accuracy of the property protection plate 41 (the condensing lens 42).

  Since the center of the condensing lens 42c located at the center in the longitudinal direction among the plural (for example, ten) condensing lenses 42 is used as a reference point, the translucent protection plate 41 is transparent at both end positions in the longitudinal direction. It is possible to minimize the influence (positional displacement) due to thermal expansion of the optical protective plate 41, the long frame 44, and the solar cell mounting plate 47, and to improve heat resistance and power generation efficiency. Become.

  In the present embodiment, each column of the condenser lenses 42 preferably includes an odd number of condenser lenses 42. With this configuration, it is possible to easily determine the positioning of the positioning pin 41p with high accuracy by applying a center line (reference line SL) that connects the centers of the two condenser lenses 42c located at the center of the row. It becomes. That is, since the positioning pin 41p can be arranged in correspondence with the center of the condensing lens 42c located at the center of the row, the position of the positioning pin 41p can be determined with good balance and high accuracy with respect to both ends of the row. It becomes possible, and it becomes possible to minimize the influence of the positional deviation at both ends of the row due to thermal expansion.

  The positioning pin 41p is bonded firmly to the edge 41f (translucent protective plate 41) with a double-sided tape 41pb, for example, and then firmly bonded with an adhesive 41pa (FIG. 2 (C)). In this configuration, the fitting to the portion 44p can be reliably performed.

  As described above, according to the solar power generation unit manufacturing method according to the present embodiment for manufacturing the concentrating solar power generation unit 40, the condensing lens 42 can be aligned with the solar cell 10 with high accuracy. It is possible to irradiate the solar cell 10 with the sunlight collected by the lens 42 with high accuracy, and it is possible to improve the power generation efficiency.

Thus, the positioning pin 41p can be easily bonded to the translucent protective plate 41 with high accuracy.

  The alignment mark and the alignment position can be set in advance appropriately, and are not limited to the center of the condenser lens 42 and the center of the imaging lens 96 illustrated. Note that it is preferable to perform alignment with the center of the condensing lens 42 and the center of the imaging lens 96 as a reference in consideration of easiness of work and accuracy.

  After the translucent protective plate 41 is placed on the pin joining adjustment base 91 (protecting plate placement step), the imaging unit holding beam 94 is lowered toward the pin joining adjustment base 91, and the pin joining jig 99 is translucent. The center of the condensing lens 42 detected by the imaging unit 95 is aligned with the center of the imaging lens 96 by adjusting the position of the translucent protection plate 41 in the state of being closely opposed to the protective protection plate 41 (correlation lens position). Combining step).

  The imaging unit 95 is arranged in correspondence with the condenser lens 42 (42c) to be aligned. That is, when the condensing lenses 42 arranged on the translucent protective plate 41 are arranged in two rows, the alignment is performed using the two rows of condensing lenses 42, so that two imaging units 95 are provided. .

  The focal length Dim of the imaging lens 96 that detects the condensing lens 42 (for example, the center as an alignment mark thereof) is substantially equivalent to the height of the pin joining jig 99 and is configured by a lens having a relatively short focal length. is there. That is, the center of the condenser lens 42 can be detected by applying the imaging lens 96 having a short focal distance Dim. Therefore, as described above, the structure of the optical system composed of the imaging unit 95 and the imaging lens 96 can be downsized and configured at low cost, and the photovoltaic power generation unit manufacturing apparatus 90 can be downsized as a whole. It becomes possible, and it can be set as the cheap and highly productive solar power generation unit manufacturing apparatus 90.

  In a state where the center of the condenser lens 42 is aligned with the center of the imaging lens 96, the positioning pin 41p is inserted into the pin insertion hole 99h formed as a through hole, and is joined (crimped) to the edge 41f (positioning pin crimping). Process). The double-sided tape 41pb (see FIG. 2) is bonded to the positioning pin 41p in advance, and the positioning pin 41p can be easily crimped to the border 41f by pressing.

  The pin joining jig 99 is fixed to the imaging unit holding beam 94. With this configuration, the positional relationship between the center of the imaging lens 96 held by the imaging unit holding beam 94 and the pin joining jig 99 (pin insertion hole 99h) can be fixed. The center of the imaging lens 96 is aligned in advance (imaging lens positioning step) on a straight line (reference line SL) defined corresponding to the two pin joining jigs 99 (pin insertion holes 99h), and the imaging lens is positioned. By performing a process in a pin joining process, which is a process different from the process, the position of the pin insertion hole 99h can be easily aligned with high accuracy with respect to the condenser lens 42 (the translucent protective plate 41 and the edge 41f). It becomes possible to do.

  After the imaging lens positioning step, the translucent protection plate 41 is placed on the pin bonding adjustment base 91 (protection plate placement step), and the position of the translucent protection plate 41 is adjusted and detected by the imaging lens 96. By aligning the center of the optical lens 42 with the center of the imaging lens 96 (correlation lens alignment step), the position of the pin insertion hole 99h is set with respect to the condensing lens 42 (the translucent protective plate 41 and the edge 41f). It can be easily aligned with high accuracy. That is, the positioning pin 41p can be easily positioned and joined with high accuracy to the edge 41f (translucent protective plate 41).

  After the positioning pin 41p is inserted into the pin insertion hole 99h and is crimped to the translucent protective plate 41 (edge 41f) (positioning pin crimping step), the imaging unit holding beam 94 is raised again with respect to the pin joint adjusting base 91. Then, the translucent protective plate 41 is taken out from the pin bonding adjustment base 91 in a state where a space is provided between the pin bonding adjustment base 91 and the imaging unit holding beam 94.

  As described above, in the pin joining process, the protective plate placement process for placing the translucent protection plate 41 on the pin joining adjustment base 91 and the position of the placed translucent protection plate 41 are adjusted to collect the condensing lens. A correlation lens positioning step for aligning the center of the lens 42 with the center of the imaging lens 96 pre-positioned in the imaging lens positioning step, and a positioning pin 41p with the center of the condenser lens 42 aligned with the center of the imaging lens 96 Is inserted into the pin insertion hole 99h of the pin joining jig 99, and the positioning pin is crimped to the edge 41f of the translucent protective plate 41.

  In addition, an imaging lens positioning step of previously aligning the center of the imaging lens 96 with a position where the center of the condenser lens 42 should be arranged is provided before the correlation lens positioning step (pin joining step). The imaging lens positioning step does not need to be performed every time the pin joining step is performed, and may be performed at an appropriate interval (for example, a lot unit of the translucent protective plate 41, a unit of work day).

  Since the position of the translucent protective plate 41 (the condensing lens 42) is adjusted using an optical system including the imaging unit 95 and the imaging lens 96, the positioning pin 41p is connected to the translucent protective plate 41 (the condensing lens). 42) can be easily joined (adhered) with high accuracy.

  In addition, when the arrangement | positioning of the condensing lens 42 in the translucent protection board 41 is 2 rows x 5 pieces (10 condensing lenses 42), when the condensing lens 42 is 30 cm square, for example, translucent protection is carried out. When the plate 41 is about 60 cm × 150 cm and the condenser lens 42 is 40 cm square, for example, the translucent protection plate 41 is about 80 cm × 200 cm, and the translucent protection plate 41 has a large outer shape. Therefore, it is preferable to use the handling machine which handles the translucent protection board 41 using the notch | incision part 91a for the mounting movement process of the translucent protection board 41. FIG.

  FIG. 7 is an explanatory view for explaining an imaging lens positioning process for positioning the imaging lens in the photovoltaic power generation unit manufacturing apparatus shown in FIG. 5, and FIG. 7A shows an imaging lens adjustment plate mounted on a pin joining jig. FIG. 5B is a plan view showing the placed state in plan view, FIG. 5B is a front view of the imaging lens adjustment plate viewed from the direction of the arrow B in FIG. It is the side view seen from the direction. In FIG. 2A, the imaging unit 95 and the imaging lens 96 are not shown. FIG. 8 is an explanatory diagram schematically showing a state in which the center of the imaging lens is positioned in the imaging lens positioning step shown in FIG.

  In the imaging lens positioning step, first, the imaging lens adjustment plate 101 is fitted in a pin-like manner into the pin insertion holes 99h of the two pin joining jigs 99 provided corresponding to the edge 41f (imaging lens adjustment plate fitting). Joint process). That is, the two pin corresponding protrusions 101p formed at both ends of the back surface of the imaging lens adjustment plate 101 are fitted into the corresponding pin insertion holes 99h.

  On the surface of the imaging lens adjustment plate 101, a condensing lens 42 (in a row) on a straight line connecting the centers of the pin-corresponding protrusions 101p (that is, a straight line connecting the centers of the pin insertion holes 99h, corresponding to the reference line SL). The reference position mark 101m for displaying the reference position SP set in correspondence with the center (the center as the alignment mark) of the condenser lens 42c) arranged at the center is a cross-shaped ruled line (the center of the cross is the reference position SP). ).

  For convenience of explanation, the reference line SL and the reference position SP are defined at the center of the condenser lens 42 (the condenser lens 42c arranged at the center of the row). It is also possible to appropriately define other positions corresponding to the alignment marks. For example, when an even number of condensing lenses 42 are arranged in each row, it is preferable to set the alignment mark corresponding to the side close to the center of the row of condensing lenses 42. The alignment mark and the alignment position can be formed by attaching an appropriate mark that does not affect the optical characteristics.

  Next, after adjusting the imaging lens 96 to correspond to the focal length Dim, the surface of the imaging lens adjustment plate 101 is observed with the imaging lens 96 to detect the reference position mark 101m. By using the detected reference position mark 101m, the center of the imaging lens 96 (center as the alignment position) Cim is aligned with the reference position SP in the direction of the arrow PCim (imaging lens position adjusting step), thereby obtaining the imaging lens 96. The pin bonding adjustment base 91 is positioned with respect to the plane (imaging lens positioning step). The position control of the imaging lens 96 can be appropriately controlled by a manipulator provided in the imaging unit 95.

  Therefore, since the center Cim of the imaging lens 96 can be optically aligned with the reference position SP by applying the imaging lens adjustment plate 101 having a simple configuration, the center of the imaging lens 96 can be easily and efficiently positioned with high accuracy. Is possible. The positioning of the imaging lens 96 can be further improved by performing the positioning for each imaging lens 96 individually.

  The pin joining jig 99 (pin insertion hole 99h) is preliminarily set and arranged corresponding to the positioning pins 41p (see FIG. 3) to be joined to the opposing edge 41f, and is fixed to the imaging unit holding beam 94. .

  The pin insertion hole 99h (pin joining jig 99) is a reference position for displaying a reference position SP corresponding to the center of the condenser lens 42 on a straight line (corresponding to the reference line SL) connecting the two pin insertion holes 99h. The imaging lens adjustment plate 101 on which the mark 101m is formed is configured to be fitted through two pin-corresponding protrusions 101p formed on the back surface (both ends corresponding to the two pin insertion holes 99h, respectively).

  With this configuration, since the imaging lens adjustment plate 101 can be easily fitted into the pin joining jig 99 (pin insertion hole 99h), the reference position mark 101m provided on the imaging lens adjustment plate 101 can be detected by the imaging lens 96. Using the reference position mark 101m, the center Cim of the imaging lens 96 is moved to the reference position SP (corresponding to the position where the center of the condensing lens 42 is to be arranged (design position of the center of the condensing lens 42)) with high accuracy. It becomes possible to align easily.

  That is, the center Cim of the imaging lens 96 corresponds to the center of the condenser lens 42 on the straight line (reference line SL) connecting the two pin insertion holes 99h arranged corresponding to the edge 41f of the translucent protective plate 41. Positioning is performed in advance by an imaging lens positioning step for aligning with the set reference position SP. Therefore, the center Cim of the imaging lens 96 can be easily positioned with high accuracy.

  In addition, since the imaging lens adjustment plate 101 has a U-shaped cross section (FIG. 7C), it is possible to ensure the strength and stability of the shape between the two pin joining jigs 99. Therefore, it is possible to ensure and display the position of the reference position SP with high accuracy.

  As described above, the pin joining jig 99 is preferably provided in a pair (two) corresponding to the edge 41f, but is not limited to this. That is, it is also possible to position and position only on one side.

  FIG. 9 is a plan view showing an outline of a state of a correlation lens positioning step in which a translucent protective plate is placed on the photovoltaic power generation unit manufacturing apparatus shown in FIG. FIG. 10 is an enlarged cross-sectional view taken along arrows XX in FIG. FIG. 11 is an explanatory diagram conceptually showing a state in which the center of the condenser lens is aligned with the center of the imaging lens by adjusting the position of the translucent protection plate in the correlation lens alignment step shown in FIG. .

  Since the basic configuration of each part is as shown in FIGS. 5 and 6, the correlation lens positioning process for mainly positioning the translucent protective plate 41 will be described.

  As described above, after the translucent protection plate 41 is placed on the pin bonding adjustment base 91 (protection plate placing step), the position adjustment jigs 97 and 98 of the pin joining adjustment base 91 are used to adjust the translucent protection plate 41. The center Cim of the imaging lens 96 that is pre-positioned by adjusting the position and detecting the center (center as an alignment mark) Cfc of the condenser lens 42 detected by the imaging lens 96 corresponding to the pin insertion hole 99h of the pin joining jig 99. (Correlation lens positioning step).

  The translucent protective plate 41 can be adjusted in position by appropriately applying pressure from the side as indicated by arrows Pra and Prb (FIG. 10). The imaging unit 95 detects the center Cfc of the condenser lens 42 and adjusts the position of the translucent protective plate 41 so that the center Cfc is aligned with the center Cim of the imaging lens 96 in the direction of the arrow PCfc, for example.

  After the center Cfc is aligned with the center Cim, the positioning pin 41p is inserted into the pin insertion hole 99h in the direction of the arrow Pins and is crimped to the edge 41f.

  FIG. 12 is an explanatory view showing the lifting control mechanism for performing the lifting control of the imaging unit holding beam in the photovoltaic power generation unit manufacturing apparatus shown in FIG. 5 in the same direction as FIG. 6, and FIG. It is a schematic structure figure, (B) is a front view of the raising / lowering gauge seen from the arrow B of (A).

  Since the basic structure of each part is as having shown in FIG. 5, FIG. 6, the raising / lowering control mechanism is mainly demonstrated.

  As described above, since the imaging unit holding beam 94 is configured to move up and down with respect to the holding beam column 93, the imaging lens 96 having a short focal length can be applied to detect the center Cfc of the condenser lens 42. Therefore, the imaging lens (imaging unit) can be downsized, and a small and inexpensive solar power generation unit manufacturing apparatus can be obtained.

  The holding beam column 93 is fixed to the column base 92 by a column fixing part 93a. The column fixing portion 93 a prevents the pin bonding jig 99 from colliding with the translucent protective plate 41 when the imaging unit holding beam 94 is lowered to bring the pin bonding jig 99 close to the translucent protective plate 41. The structure also functions as a stopper (see the translucent protective plate 41, the imaging unit holding beam 94, the column fixing unit 93a, and the pin joining jig 99 shown by a two-dot chain line in the figure).

  The imaging unit holding beam 94 is connected to the holding beam column 93 via the beam connecting unit 94a and can move up and down. In other words, the imaging unit holding beam 94 can be moved up and down by sliding the beam connecting unit 94 a along the holding beam column 93. A lift control claw 93b and a lift gauge 93c are provided as a lift control mechanism after the imaging unit holding beam 94 is lifted and lowered and fixed at that position.

  The lifting control claw 93b is arranged at the end of the holding beam support 93 and engages with the lifting gauge 93c. The lifting gauge 93c is fixed to the imaging unit holding beam 94 at a position facing the lifting control claw 93b. Therefore, the lifting / lowering gauge 93c is stopped by engaging the lifting / lowering control claw 93b with the claw engagement hole 93d of the lifting / lowering gauge 93c, thereby stopping the lifting / lowering of the imaging unit holding beam 94.

  Further, by rotating the lifting control claw 93b in the direction of the arrow Rot to separate the lifting gauge 93c and the lifting control claw 93b, the imaging unit holding beam 94 can be moved up and down. That is, after the imaging unit holding beam 94 is moved up and down to an appropriate position, the imaging unit holding beam 94 is fixed at an appropriate position by engaging the elevation control claw 93b with the claw engagement hole 93d of the elevation gauge 93c ( Can be stopped).

  It should be noted that the tip of the position adjusting jig 98 is in contact with the side surface of the translucent protective plate 41 and the position of the translucent protective plate 41 is adjusted.

  FIG. 13 is an explanatory view showing an enlarged schematic structure of the position adjusting jig in the photovoltaic power generation unit manufacturing apparatus shown in FIG. 5, and (A) shows a side state of the position adjusting jig for pressurization. A side view, (B) is a top view which shows the plane state of the position adjustment jig for pressurization, (C) is a side view which shows the side surface state of the position adjustment jig for stationary.

  The position adjusting jig 97 (FIGS. (A) and (B)) includes a fixing portion 97a for fixing to the pin joint adjusting base 91, and a contact portion 97c for contacting the translucent protective plate 41 to adjust the position. An operation unit 97b to be controlled is provided. The operation unit 97b can be configured by a general manipulator. The contact portion 97c is made of resin in order to prevent the translucent protective plate 41 from being damaged.

  Further, the position adjusting jig 98 ((C) in the figure) controls the fixing portion 98a for fixing to the pin joint adjusting base 91 and the abutting portion 98c for contacting the translucent protective plate 41 and adjusting the position. An operation unit 98b is provided. The operation unit 98b can be configured as a general plunger configuration. The contact portion 98c is made of resin in order to prevent the translucent protective plate 41 from being damaged.

It is a side view which shows the positional relationship with a translucent protection board seeing from the code | symbol B direction.

  The pin joining jig 99 has a fixed portion 99a that is appropriately fixed to the imaging unit holding beam 94 by screwing or the like, and a pin insertion having a pin insertion hole 99h that extends in a plate shape from the bottom of the fixed portion 99a and inserts the positioning pin 41p. It consists of a part 99b. In addition, the bottom portion of the pin insertion portion 99b has a notch 99c in a portion corresponding to the condensing lens 42.

  Since the notch 99c is provided, the pin joining jig 99 can be superimposed on the condenser lens 42, and the positioning pin 41p can be arranged and joined at a position close to the condenser lens 42. Therefore, the positioning pin 41p can be positioned with high accuracy with respect to the condenser lens 42 (translucent protective plate 41).

  After the center Cfc of the condenser lens 42 is aligned with the center Cim of the imaging lens 96 (correlation lens positioning step), the positioning pin 41p is inserted into the pin insertion hole 99h and is crimped to the rim 41f (positioning pin crimping step). . For example, a double-sided tape 41pb (see FIG. 2) is bonded in advance to the tip of the positioning pin 41p. Thereafter, the pin joining jig 99 (imaging unit holding beam 94) is raised to remove the translucent protective plate 41 from the pin joining adjusting base 91, and the adhesive 41pa is applied to the positioning pins 41p to ensure the adhesive strength.

  According to the present embodiment, the positioning accuracy of the positioning pin 41p can be set to an error of 0.1 mm or less, condensing characteristics are good, and concentrating sunlight with excellent condensing performance and heat resistance. The power generation unit 40 can be manufactured.
