Description

UV glue pre-curing time measuring device and method

technical field

The invention relates to a device and method for measuring the pre-curing time of ultraviolet glue.

Background technique

The basic principle of UV glue curing is that the photoinitiator in UV glue is excited into free radicals and cations under the irradiation of ultraviolet light, thereby initiating a series of polymerization reactions in the material, and changing from liquid to solid within a few seconds. Due to its short curing time, low cost, low pollution and low curing temperature, UV glue is often used for assembly, fixing, positioning and bonding of optical devices and electronic components.

In the optical coupling of the optical module package, it is often necessary to use ultraviolet glue to complete the fixing and bonding of the device. In the actual production process, the optical path coupling takes a long time and the production capacity is limited. Therefore, it is necessary to shorten the curing time of UV glue. For a given type of UV glue, the manufacturer's data sheet will give the complete curing time. However, when the optical path is coupled, it usually only needs to be pre-fixed, that is, it does not need to be completely cured, as long as the degree of curing can meet the requirements, and the subsequent process will carry out secondary curing. How to accurately measure the pre-curing time is of great significance for improving productivity.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

1-3 is an embodiment of the present invention, comprising vibration test platform 1, sub-carrier 2, laser assembly 31, collimating lens assembly 32, converging lens 33, detector array 34, wherein laser assembly 31, collimating lens The component 32 constitutes a laser emitting component, and the laser component 31 , the collimating lens component 32 , the converging lens 33 , and the detector array 34 constitute the optical path testing module of this embodiment.

In this embodiment, the laser assembly 31 includes a laser chip 311 and a laser heat sink 312 . The wavelength of the laser light emitted by the laser chip 311 matches the response wavelength of the detector array 34 , so that the emitted laser light can be detected by the detector array 34 . The laser chip 311 uses a commonly used DFB laser with a wavelength of 1310nm and is equipped with a stable output DC drive power supply.

The laser heat sink 312 is electrically connected to the laser chip 311 and fixed together on the sub-carrier 2 , and the electrical connection is completed by bonding gold wires with a wire bonding machine. The laser heat sink 312 includes a temperature control module composed of a thermistor, a TEC (semiconductor cooler) and a control circuit, and the temperature control accuracy is 0.01°C. The laser chip 311 is sensitive to temperature, and the wavelength of the emitted laser light will drift due to temperature changes. Therefore, controlling the temperature can improve the stability of the output of the laser chip 311, and the accuracy in the subsequent process of measuring light intensity is higher.

In this embodiment, the collimating lens assembly 32 includes a collimating lens 321 and a lens base 322 . The collimator lens 321 is an aspherical lens with an effective numerical aperture of 0.5, so that the laser light emitted by the laser chip 311 can be better converted into parallel light by the collimator lens 321 . The collimator lens 321 is fixed on the lens base 322 , and the lens base 322 is fixed on the sub-carrier 2 .

In this embodiment, the converging lens 33 adopts an aspheric lens to improve the imaging quality. The converging lens 33 is bonded on the sub-carrier 2 with ultraviolet glue whose pre-curing time is to be tested.

In this embodiment, the detector array 34 is fixed on the sub-carrier 2 . The detector array 34 uses an infrared PIN detector array, so the lasing wavelength of the laser chip 311 is within the spectral response range of the detector array 34 . The detector array 34 can also use area array CCD or CMOS sensors. It can be understood that the detector array 34 should also be equipped with a detector array power supply module, a detector array data acquisition module and a computer, so that the detector array 34 can work normally and transmit data.

In this embodiment, the laser assembly 31, the collimating lens assembly 32, the converging lens 33 and the detector array 34 are coaxial and of the same height, so that the detector array 34 can record the light intensity of the laser emitted by the laser emitting assembly after the converging lens 33 . That is, the laser light emitted by the laser chip 311 passes through the collimating lens 321 and the converging lens 33, and the light intensity is recorded by the detector array 34, so as to pass through the time of irradiating the UV glue according to the UV light source and the light caused by the pre-curing of the UV glue. Strong changes determine the pre-curing time of UV glue.

More specifically, after the condensing lens 33 is bonded to the sub-carrier 2 with the ultraviolet glue whose pre-curing time is to be tested, the detector array 34 is used to record the laser light emitted by the laser chip 311 at this time through the collimating lens 321 and the condensing lens 33. After the light intensity. Turn on the vibration test platform 1 to perform a vibration test. After the vibration test is completed, use the detector array 34 again to record the light intensity of the laser light emitted by the laser chip 311 after passing through the collimating lens 321 and the converging lens 33 . It is understandable that after the pre-curing of the UV adhesive is completed, its shear strength and tensile strength are very high, and the light intensity will hardly change before and after the vibration test. The light intensity changes before and after the test. When the light intensity change value is less than one thousandth, it can be considered that the light intensity has not changed. When the light intensity recorded by the detector array 34 changes, that is, the pre-curing of the ultraviolet adhesive has not been completed, at this time, the ultraviolet irradiation time can be increased to complete the pre-curing of the ultraviolet adhesive. After repeated experiments, the critical irradiation time at which the light intensity does not change can be measured, thereby measuring the pre-curing time of the UV adhesive.

In this embodiment, the sub-carrier 2 and its upper laser assembly 31, collimating lens assembly 32, converging lens 33, and detector array 34 can be replaced as a whole to meet the testing requirements for different UV adhesives, or to carry out new experiments.

In this embodiment, a cantilever mechanism 4 is provided above the converging lens 33 and can be withdrawn at any time. In this embodiment, the cantilever mechanism 4 is installed on the ceiling, but the cantilever mechanism 4 can also be mounted on one side of the vibration test platform 1 by using a floor stand and extended over. The cantilever mechanism 4 includes a moving device 41 , a telescopic block 42 and a vacuum suction nozzle 43 . The moving device 41 can move the cantilever mechanism 4 in two directions perpendicular to each other in the horizontal plane. The telescopic block 42 is installed below the moving device 41 and can move vertically, so that the cantilever mechanism 4 can be extended and shortened vertically. The vacuum suction nozzle 43 is installed on the lower end of the telescopic block 42 , which can absorb and move the converging lens 33 , and can also fix the converging lens 33 on a certain position on the sub-carrier 2 .

In this embodiment, a glue spraying assembly 5 is also included, which is used to apply the ultraviolet glue to the designated position. In the present embodiment, the glue spraying assembly 5 includes a glue spraying device 52 and a first clamping arm 51, the glue spraying device 52 is used to spray the ultraviolet glue to be tested, and the first clamping arm 51 is used to hold the glue spraying device 52 Connected to the cantilever mechanism 4. Although the present embodiment connects the glue spraying device 52 to the cantilever mechanism 4 through the first clamping arm 51, as long as the glue spraying device 52 can be guaranteed to smear the ultraviolet glue to be tested to a designated position, the glue spraying device 52 can be erected separately on the One side or other erection methods are also available.

In this embodiment, the glue spraying device 52 is provided with a linear guide rail 53, which can make the nozzle 521 of the glue spraying device 52 move along the axis direction of the glue spraying device 52, so that the nozzle 521 can be close to and away from the designated position to operate the spraying glue . Similarly, as long as the glue spraying device 52 can ensure that the ultraviolet glue to be tested is applied to the designated position, the linear guide rail 53 is not provided, or other methods are also acceptable.

In this embodiment, an illumination component 6 is also included, which is used to irradiate ultraviolet rays to light-cure the ultraviolet glue to be tested. In this embodiment, the illumination assembly 6 includes an ultraviolet light source 62 and a second clamping arm 61 , the ultraviolet light source 62 is used for irradiating ultraviolet rays, and the second clamping arm 61 is used for connecting the ultraviolet light source 62 to the cantilever mechanism 4 . Although the present embodiment connects the ultraviolet light source 62 to the cantilever mechanism 4 through the second clamping arm 61, as long as the ultraviolet light emitted by the ultraviolet light source 62 can be irradiated to a designated position, it is also possible to erect the ultraviolet light source 62 alone or other erection methods. Can. Simultaneous irradiation of multiple UV light sources can improve the curing efficiency and curing uniformity of UV adhesives.

It can be understood that this embodiment also includes a power supply, which is used to provide energy for the device of the present invention; a computer, which is used to control the actions of the device and collect and process data; The mouth 43 provides suction. In actual operation, other utensils such as tweezers may also be used, which will not be repeated here.

The method for measuring the pre-curing time of the ultraviolet glue in this embodiment will be described in detail below.

First, use the vacuum suction nozzle 43 to absorb the converging lens 33, move the converging lens 33 to the target position through the moving device 41, then use the telescopic block 42 to adjust the height of the converging lens 33, and place the converging lens 33 on the sub-carrier 2 to make the laser assembly 31. The collimating lens assembly 32 , the converging lens 33 and the detector array 34 are coaxial and of the same height, so that the laser light emitted by the laser chip 311 can be recorded by the detector array 34 after passing through the collimating lens 321 and the converging lens 33 . Write down the target position where the converging lens 33 is located at this time, and then use the vacuum suction nozzle 43 to remove the converging lens 33 .

Cooperate with the operation of the moving device 41 and the linear guide rail 53, so that the glue spraying device 52 starts to move from the initial position, and the nozzle 521 is moved to the target position, so that the glue spraying device 52 can apply the UV glue to be tested to the target position through the nozzle 521 , that is, spraying glue is completed. After spraying the glue, reset the glue spraying device 52 to the initial position.

Operate the moving device 41 and the telescopic block 42, use the vacuum nozzle 43 to move the converging lens 33 to the target position, place it on the UV adhesive, and use the vacuum nozzle 43 to fix the converging lens 33 to prevent deformation during the subsequent UV adhesive pre-curing process This causes the converging lens 33 to shift. Turn on the ultraviolet light source 62 to irradiate the converging lens 33 to reach the initial pre-curing time T ₀ , so that the ultraviolet glue to be tested undergoes a certain photocuring under ultraviolet irradiation. In this embodiment, the initial pre-curing time T ₀ is set to 5 seconds.

When the initial pre-curing time _T0 is set to be small, it can ensure that the ultraviolet glue reaches a certain photocuring, but it is not completely photocured. At this time, after the ultraviolet glue is bonded to the converging lens 33, after the vibration test of the vibration test platform 1, it will produce The slight displacement does not cause the converging lens 33 to fall off from the sub-carrier 2 . Due to the small displacement, the detector array 34 can detect the change of the light intensity, thus confirming that the pre-curing time of the ultraviolet glue has not been reached, and further light curing is required.

After the initial pre-curing time T ₀ , that is, after 5 seconds, turn off the ultraviolet light source 62, release the vacuum nozzle 43, and remove the cantilever mechanism 4 and the glue spraying assembly 5 and lighting assembly 6 thereon. At this time, the laser component 31 is turned on to emit laser light, and the optical path test is performed by using the optical path test module, and the detector array 34 can record the initial light intensity Q ₀ at this time.

Turn off the laser chip 311, turn on the vibration test platform 1 to carry out the vibration test, turn off the vibration test platform 1 after 10 minutes, turn on the laser component 31 to emit laser light, use the optical path test module to carry out the optical path test, and the detector array 34 can record the time The light intensity Q ₁ .

Due to the setting of this embodiment, after the initial pre-curing time T ₀ , that is, after 5 seconds, the ultraviolet glue does not reach the pre-curing state, and after the vibration test, the converging lens 33 will be slightly displaced, so that Q ₁ must be the same as Q ₀ Not the same, but also need to increase the lighting time.

The pre-cured ultraviolet glue is removed, the converging lens 33 is removed from the sub-carrier 2, and the experimental measurement is restarted. Move back the cantilever mechanism 4, use the vacuum suction nozzle 43 to fix the converging lens 33, turn on the ultraviolet lamp 62 to irradiate the converging lens 33, and add the ultraviolet light source 62 irradiation time T ₁ on the basis of the initial pre-curing time T ₀ , in this embodiment T ₁ for 1 second. Use the detector array 34 to record the initial light intensity Q ₀ at this time, then turn off the ultraviolet light source 62, loosen the vacuum nozzle 43, and remove the cantilever mechanism 4 and the glue spraying assembly 5 and lighting assembly 6 on it. Turn on the vibration test platform 1 to carry out the vibration test, and turn off the vibration test platform 1 after 10 minutes. At this time, the laser component 31 is turned on to emit laser light, and the optical path test module is used to perform the optical path test. The detector array 34 can record the light intensity at this time _Q2 .

Comparing Q ₂ and Q ₀ , if Q ₂ and Q ₀ are the same, it can be judged that the pre-curing of the UV glue has been completed, and output the pre-curing time T=T ₀ +2T ₁ at this time, that is, T=5+2=7 seconds as UV glue pre-curing time.

If Q ₂ is not the same as Q ₁ , repeat the above steps of adding curing time T ₁ , vibration test and optical path test until Q _n is the same as Q ₀ , and the output time T=T ₀ +n*T ₁ is used as UV glue pre-curing time. Where n is the number of times that the UV light source is repeatedly irradiated to the UV glue to be tested.

In this embodiment, the experiment is repeated until Q ₅ is the same as Q ₀ , therefore, the pre-curing time of the UV glue used in this embodiment is T=T ₀ +n*T ₁ =5+5*1=10 seconds.

In some other embodiments, if the initial pre-curing time T ₀ is not limited to be small, it may appear that after the first ultraviolet light source irradiation, the measured light intensity Q ₁ is already the same as the initial light intensity Q ₀ , at this time The initial pre-curing time T ₀ can be reduced, and then experimental measurements are carried out sequentially until the light intensity Q _n in a certain experiment is different from the initial light intensity Q ₀ , and the UV glue pre-curing time T=T ₀ -(n- 1)*T ₁ , where n is the number of times that the UV light source is repeatedly irradiated to the UV glue to be tested. That is to say, after reducing the initial pre-curing time T ₀ in a certain experiment, the light intensity Q _n at this time is different from the initial light intensity Q ₀ , so it is understandable that the pre-curing time can be determined as the upper The time during one experiment is thus T=T ₀ -(n-1)*T ₁ .

In this embodiment, the initial pre-curing time T ₀ is set to 5 seconds, and the single adjustment time T ₁ is 1 second. However, in actual operation, both the initial pre-curing time T ₀ and the single adjustment time T ₁ can be selected according to requirements, for example, the single adjustment time T ₁ is set to 0.5 seconds or 0.1 seconds. At this time, the accuracy of the pre-curing time T of the ultraviolet glue determined will be higher.

The UV glue pre-curing time measurement device and method of use provided by the present invention, compared with the current method of selecting the pre-curing time based on experience, the results obtained through experimental testing are more accurate, which improves the reliability of optical module production and improves the optical efficiency. Capacity for module production.

It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
