And a table moving device for moving the component supply table so as to select a unit to be positioned manually. The component supply units are mounted on the component supply table in the number corresponding to the type or number of electronic components to be mounted on the printed circuit board, and the component supply unit moves the component supply unit to the printed circuit board of the electronic component. The electronic components are supplied to the component mounting device by being positioned at the supply position in the mounting order.

[0004]

Generally, the type or number of electronic components mounted on one printed circuit board is not so large, but in many cases, the component supply table can be used for the electronic components mounted. Since it is made assuming that the number of types or number is the largest, it will be large, and the table moving device will have to have a large driving force, and since the inertia is large, the response will be poor and high-speed operation will be difficult. There was a problem of inefficiency. In addition, there is a problem that the vibration generated when the component supply table starts to move or stops is large, the direction of the electronic component may change or the electronic component may tilt, and the component mounting device may easily hold the electronic component. Further, when only one component supply table is provided in one mounting device, if there are no electronic components in the component supply unit on the component supply table, the mounting device is stopped and the component supply unit is replaced or There is also a problem that the operating rate of the expensive mounting device is lowered because the electronic parts must be replenished. The present invention has been made with the object of obtaining an electronic component supply device capable of solving these problems.

[0005]

To this end, in the electronic component supply apparatus according to the present invention, (1) a component supply unit that holds a large number of electronic components of one type each has a component supply section of each unit along a straight line. A plurality of first component supply tables and second component supply tables which are respectively mounted on the table in a lined state, and (2) the first component supply table and the second component supply table in a direction parallel to the straight line, A common work area for supplying electronic parts from each of the plurality of part supply units on the first part supply table and the second part supply table, and a first part supply table save provided on each side of the work area. A table guiding device for respectively guiding the area and the second component supply table evacuation area, and (3) the first component supply table and the second component supply table. One of the parts supply tables is kept in the retreat area, the other is moved to the work area, and each parts supply unit of the plurality of parts supply units on the other parts supply table is predetermined. A table moving device for selecting a unit for selectively positioning at a supply position, and (4) no electronic components in at least one of the plurality of component supply units on the component supply table in the work area, or According to the component end detection means for detecting the loss of the component, and (5) the component end detection by the component end detection means, the table moving device is supplied with the component supply table in the work area and the component supply in the retreat area. Table replacement command means for commanding that the table should be replaced.

In a preferred aspect of the present invention, an electronic component supply device has, in addition to the above-mentioned components (1) to (5),
Preparation completion detecting means for detecting whether or not the parts supply table in the evacuation area is in a ready state for parts supply,
When the preparation completion detecting means does not detect the preparation completion, the table replacement prohibiting means for prohibiting the replacement of the component supply table despite the detection of the component end by the component end detecting means is configured.

In another desirable mode, in addition to the above-mentioned components (1) to (5), a component end notification means for notifying an operator of the component end in response to the component end detection by the component end detection means. Is configured to include.

[0008]

With the size of the first component supply table and the second component supply table, the component supply units required when the types or the number of electronic components mounted on the printed circuit board are not so large are all included in one table. If the number or types of electronic components to be mounted on the printed circuit board are the largest, the size of both component supply tables should be large enough to mount all the required component supply units. Thus, when one component supply table is sufficient for supplying electronic components to be mounted, only one component supply table is moved, and when there are many electronic components, both component supply tables are alternately or simultaneously used. Electronic components can be supplied by moving them. Then, while the component supply is being performed by one component supply table, at least one component of the component supply unit on the component supply table is about to disappear Detected by the component end detection means, and in response thereto, the table replacement command means causes the table moving device to move the component supply table in the work area to the evacuation area and to move the component supply table in the evacuation area to the work area. Move the table to move.

Further, in the electronic component supplying apparatus of the desirable mode equipped with the preparation completion detecting means and the table replacement prohibiting means, when the component supply table in the save area is not in the ready state, the component end detecting means is Even when the end of the parts is detected, the table replacement prohibiting means prohibits the table replacement.

In addition, in the electronic component supply apparatus of the desirable mode equipped with the component end notification means, the component end notification means notifies the operator of the fact in response to the detection of the component end by the component end detection means.

[0011]

In the component supply apparatus of the present invention, the sizes of the first component supply table and the second component supply table are made assuming that the type or number of electronic components to be mounted is the largest. Since it can be made smaller than the conventional one, it has good responsiveness and can be moved at high speed to improve work efficiency.
Since the vibration generated at the time of stopping is small, the direction of the electronic component is not changed or tilted, and the effect of reducing component supply errors can be obtained. If the number or types of electronic components to be mounted on one printed circuit board is small and all required electronic component supply units can be mounted on one component supply table, the same combination can be applied to both component supply tables. If the electronic parts in the operating component supply table are exhausted by mounting the electronic components of the above, the component supply table is moved to the retreat area, while the other component supply table is moved to the work area to perform the work. Because the necessary work such as replacement of the component supply unit and replenishment of components can be performed on the component supply table in the save area while electronic components are being supplied by the component supply table in the area, Since it is not necessary to stop the component supply device, the component supply efficiency is improved. Moreover, since the above table is automatically replaced, it is not necessary for the worker to be near the parts supply device when the table is replaced, and the parts are supplied while parts are being supplied by the next parts supply table. It is sufficient to replace the component supply unit on the component supply table or replenish electronic components after completion of the process.

Further, when the electronic component supply device is equipped with the preparation completion detecting means and the table replacement prohibiting means, the component supply table which has not been prepared is moved to the work area and a component supply error occurs. It is possible to obtain a peculiar effect that can reliably prevent this.

Further, in the case where the component notification detecting means is provided, since it is notified that the electronic components in the component supply table are about to be exhausted or has been exhausted, the worker is constantly informed that the electronic components are exhausted. It is not necessary to pay attention, and it has a unique effect of facilitating work management.

The ones located at both ends of the 8 are the supply positions 160, respectively.
The working range common to both the component supply tables 95 and 99 while being positioned is, the component supply tables 95 and 99 are alternately moved in the work region to supply electronic components during component supply, While one component supply table is in the work area, the other component supply table is evacuated onto a portion of the guide rail 150 adjacent to the portion forming the work area so as not to interfere with the component supply table in operation. .. The component supply tables 95 and 99 are respectively retracted to positions on the opposite sides of the work area, and these positions are dedicated retract regions for the first and second component supply tables 95 and 99, respectively. The rail 150 has a length sufficient for the two component supply tables 95 and 99 to move between the work area and the retreat area. The guide rail 150 constitutes the table guide device.

The electronic component mounting apparatus configured as described above is controlled by the control device shown in FIG. In the figure, 170 is a CPU (central processing unit), and this CPU
Reference numeral 170 denotes an operation start switch, a component mounting mode changeover switch as a mode selecting means, and a component supply unit 98
An operation device 172 having various operation parts, such as an input device for inputting the completion of replacement of the device and the type of the printed circuit board on which the electronic component is to be mounted, is connected. A ROM (Read Only Memory) 174 and a RAM (Random Access Memory) 176 are also connected to the CPU 170. R
The OM 174 starts a program for three component mounting modes that can be executed by this mounting apparatus, and also composes components according to the types of electronic components to be mounted on the printed circuit board, the mounting position, the mounting sequence, the moving order of the printed circuit board, and the mounting sequence of the electronic components. A program and the like for moving the component supply tables 95 and 99 so as to supply electronic components to the mounting device 18 are stored.

The CPU 170 is further provided with a first component supply table moving motor drive circuit 178, a second component supply table moving motor drive circuit 180, a substrate loading device drive circuit 182, a substrate unloading device drive circuit 184, and a substrate support device drive. A circuit 186 and a component mounting device drive circuit 188 are connected to the motor 156 and the motor 15 respectively.
8, the board loading device 12, the board unloading device 14, the board supporting device 16, and the component mounting device 18 are connected, and the tape end detection is performed via the interface 190 to detect that the electronic components of the component supply unit 98 are gone. A sensor 192 and a display device 194 (see FIG. 2) for indicating to the operator that the size of the printed circuit board to be mounted changes are connected.

A program for the three component mounting modes,
The drive motors 156, 158 and the feed screw 15 are the programs for moving the parts supply tables 95, 99 and the part of the control device for executing these programs.
2, 154 and the motor drive circuits 178, 180 together form a table moving device.

3 which can be executed by this electronic component mounting apparatus
One of the component mounting modes can be selected by the operator by operating a mode selector switch (not shown). Normally, electronic components are mounted in the first mode shown in the flowchart of FIG. This mode
This is a case where there are not many kinds or a large number of electronic components mounted on one printed circuit board and all the necessary component supply units 98 can be mounted on either one of the tables 90 and 92. Note that, in FIG. 10, the operation described in the solid line frame is due to the mounting device,
What is described in the frame of the chain double-dashed line is due to the manual work of the operator, and the same applies to FIG. 11.

In this mode, prior to the start of operation, the type of the printed circuit board on which the electronic component is mounted is input, and the component supply unit 98 required for mounting the electronic component is set.
The tables 90 and 92 are mounted in a predetermined order. The mounting order may be the order of mounting the electronic components on the printed circuit board or may be different, but in any case, it is predetermined, and the tables 90 and 92 are determined according to the mounting order and the mounting order of the electronic components on the printed circuit board. The movement path in the work area of is set and stored in the ROM 174. Both the tables 90 and 92 have been evacuated to the evacuation area before the operation is started.
After mounting 8 to form the first component supply table 95 and the second component supply table 99, when the mounting apparatus is operated, the first component supply table 95 is moved to the work area, and the component supply unit 98 is sequentially operated. Positioned at the supply position 160, the electronic component is supplied to the component mounting device 18, and the component mounting device 18 receives the electronic component and mounts it at a predetermined position on the printed circuit board.

Then, when the electronic component of any one of the plurality of component supply units 98 is used up, it is the tape end detection sensor 1 as the component end detection means.
Detected by 92. This detection can be performed, for example, by causing the sensor 192 to generate a signal when the suction pipe 86 has not sucked the electronic component twice in a row, and the CPU 170 determines whether the electronic component is detected based on the detection signal. While moving the one component supply table 95 to the retreat area, the second component supply table 99 is moved to the work area,
The second component supply table 99 is made to supply electronic components. The operator is informed that the electronic parts are exhausted by means of a parts end notification means such as lighting of an indicator lamp provided on the main body frame 10, and the operator replaces the parts supply unit 98, which has no electronic parts, with a new one. After that, the end of the exchange is input to the CPU 170. Then, if any of the electronic components of the component supply unit 98 mounted on the second component supply table 99 runs out, the CPU 170
Moves the second component supply table 99 to the retreat area based on the signal from the sensor 192. At this time, if the replacement of the component supply unit 98 of the first component supply table 95 is not completed, the first component supply table 95 is moved after waiting for the input of the replacement completion. The replacement of 98 is normally completed before there are no electronic components in the second component supply table 99, and the CPU 170 replaces the first component supply table 95 with the second component supply table 99 and immediately shifts to the work area. The electronic parts can be moved, and the electronic parts can be continuously mounted without stopping.

As is clear from the above description, the input completion device of the operating device 172 for inputting the completion of the replacement of the parts unit constitutes the preparation completion detecting means. Further, in the part shown in FIG. 10 of the program of the three component mounting modes stored in the ROM 174, if the tape end is detected, one of the first and second component supply tables 95 and 99 is The table replacement command means is configured by being moved to the retreat position and the other one being moved to the work area, and the table replacement is not performed unless there is a replacement end input. Table replacement prohibition means is configured.

After mounting the electronic parts on a predetermined number of printed circuit boards, when mounting the electronic parts on different types of printed circuit boards, the electronic parts of the table are arranged in the order shown in the flowchart of FIG. The exchange will be done automatically. The mode accompanied by this automatic setup change is the second mounting mode. At this time, for example, the first component supply table 95 is in the work area and is in operation, and the supply of the electronic components by the first component supply table 95 completes the mounting of the electronic components on the predetermined number of printed circuit boards. In this case, the operator switches the mode changeover switch to the automatic setup change mode and inputs data indicating the type of the printed circuit board to be mounted next from the operation device 172. Further, the component supply unit 98 of the second component supply table 99, which has been evacuated to the evacuation area, is replaced with one having electronic components for the printed circuit board to be mounted next, and when the exchange is completed, the completion of setting is completed. input. If the type of printed circuit board to be mounted next changes, the type or number of electronic components to be mounted and / or the size of the printed circuit board will change. In either case, it is possible to switch to the automatic setup change mode. For example, even if a predetermined number of printed circuit boards are mounted and the automatic setup change is completed, the second component supply table 99 in the retreat area is prevented from moving until the setting completion is input. ing.

If the printed boards to be mounted next have the same size and only the type or number of electronic components to be mounted are different, it is only necessary to switch the tables, and the set number of mounted components can be mounted. When the completion of setting the component supply unit 98 to the second component supply table 99 is already input at the time of completion, the table is replaced immediately after the automatic setup change for changing the electronic component mounting program is performed. Then, the electronic components are mounted on the next printed circuit board.

When the size of the printed circuit boards to be mounted next is different, the display device 194 notifies the operator based on the input of the type of the printed circuit boards, and the setting is made. After the mounting of the number of sheets is completed, in addition to changing the program, automatic setup change including automatic position adjustment of the sub-positioning member 38 in the substrate supporting device 16 is performed. After receiving the notification from the display device 194, the operator operates the handle 54 after the automatic setup change and operates the handle carrying-in device 12 and the carrying-out device 14 between the conveyor belts 40 and 42 and between the guide plates 44 and 46. The width between the guide bars 32 and 30 is adjusted, and after completion, the adjustment completion is input. If the setting of the component supply unit 98 in the second component supply table 99 is already completed before the completion of the adjustment, the tables are replaced after the above-mentioned setup change is completed, and the electronic components are mounted. Be seen. If the setting of the component supply unit 98 is not completed, the table is replaced after the input of the completion of the setting is performed, and the electronic components are mounted.

Another mode which can be executed by this mounting apparatus is that there are many kinds or a large number of electronic parts to be mounted on the printed circuit board, and only one of the first table 90 and the second table 92 supplies necessary parts. Unit 9
8 cannot be installed, and both tables 90 and 9
This is a mounting mode in the case of mounting in two. In this case, the first and second component supply tables 95,
99 is regarded as one component supply table and can be alternately moved to the work area so as to supply electronic components in the mounting order to the printed circuit board. The component supply units are mounted in the tables 90 and 92 in the mounting order. By doing so, the component supply tables 95 and 99 need only be replaced once when mounting the electronic components on one printed circuit board.

As is clear from the above description, in the mounting apparatus of this embodiment, the component supply unit 98 is mounted when the types or the number of electronic components to be mounted on the printed circuit board are not large in each table 90, 92. The size is sufficiently large, and the size may be smaller than that in the case where the table is formed on the assumption that there are a large number or types of electronic components. Therefore, the operation responsiveness of the first and second component supply tables 95, 99 is good, and the first and second component supply tables 95, 99 can be moved at a high speed, so that the work efficiency can be improved and the movement start
Vibration generated at the time of stoppage is small, the electronic parts are less likely to tilt or change their postures, and the effect of reducing electronic component suction errors by the component mounting device 18 is obtained.

Further, in the first and second mounting modes, while one component supply table is in the work area and supplies components, the component supply unit 98 of the other component supply table in the retreat area is supplied. Since the replacement can be performed in parallel, the setup replacement can be completed in a short time when the electronic components are used up, and the operation rate of the mounting apparatus can be improved.

In the above embodiment, the feed screw 1
52 and 154 are dedicated drive motors 156 and 15 respectively.
Although it is designed to be rotated by eight, the rotation transmission of the drive motor is switched by a clutch so that both drive screws 152, 154 are driven by one drive motor.
It is also possible to rotate.

Further, the table guide device and the table moving device respectively include a guide rail 150, a feed screw 152, and a feed screw 152.
It is not limited to the one constituted by 154 and the drive motors 156, 158, various forms can be adopted, and the component supply unit is not limited to the one in the above embodiment. In addition, although not exemplarily illustrated, the present invention can be implemented in various modified and improved modes based on the knowledge of those skilled in the art.
