[0002] The module needs to be tested before assembly. Manual testing is mostly used during the module testing process. Generally, the module is powered on, the display status of the product is observed, and measurements are taken to ensure the yield of the final product. Currently, a simple test stand is basically used to test the optical characteristics of the module. Some small-sized products are in a suspended state after being connected to the simple electrical test stand due to the short FPC length of the sample, and cannot be measured normally. Even if they can be placed flat on the test platform of the optical tester with the help of external objects, when the measurement point platform moves by itself, the measurement sample will also move due to external force, thereby affecting the accuracy of the measurement position and causing misjudgment of the measurement result. The tester needs to manually calibrate and adjust the sample placement multiple times, which reduces the test efficiency and affects the accuracy of the test results. Utility Model Content

[0027] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As described in the background art, currently, only a simple test fixture is used. In the optical test of the module, after the sample is positioned for testing, when the test sample is affected by the movement of the equipment test platform, it is easy to fall off the test fixture, the position is moved, and it is difficult to locate, and it is necessary to repeat the calibration and positioning many times, thus affecting the test accuracy and test efficiency.

[0029] To solve this technical problem, the present utility model provides a module optical test fixture. The module to be tested can be stably clamped in the fixture, and problems such as sample offset, sliding, and dropping will not occur. Moreover, it can be accurately positioned and calibrated when debugging the equipment, greatly improving the test efficiency.

[0030] Specifically, please refer to Figures 1-6 , the module optical test fixture specifically includes:

[0031] The module 1 to be tested and the transfer FPC 2. A module FPC 3 is provided on the module 1 to be tested, and the transfer FPC 2 is used for detachable connection with the module FPC 3;

[0032] The positioning fixture base 4. A module positioning groove 5 is formed on the upper surface of the positioning fixture base 4. The module positioning groove 5 is stepped. A through groove 6 communicating with the module positioning groove 5 is formed on the front surface of the positioning fixture base 4. Positioning columns 7 are fixedly connected to the four corners of the lower surface of the positioning fixture base 4.

[0033] The module optical test fixture provided by the utility model places the sample of the module to be tested 1 in the multifunctional dedicated module positioning groove 5 by designing a dedicated module positioning groove 5 and a fixture made of red pad wood. Since positioning columns 7 corresponding to the positioning holes 9 on the test platform 8 are arranged around the positioning fixture seat 4, the red pad wood fixture is fixed on the test platform 8 by the positioning columns 7 and the positioning holes 9. In this way, when this fixture is used and multiple point measurements are required, as the test platform 8 moves by itself, the module to be tested 1 is firmly positioned in the fixture without problems such as sample displacement, sliding and falling. It can also be accurately positioned and calibrated when debugging the equipment, thereby greatly improving the test efficiency. In addition, by designing a soft and relatively long adapter FPC2 to connect the module FPC3 on the module to be tested 1, the problem of difficulty in connecting the module to be tested 1 and the test frame caused by the length or shape limit of the module FPC3 of the module to be tested 1 can be effectively solved. At the same time, when switching the test screen, the placement of the sample will not be affected, thereby avoiding adverse effects on the accuracy of the measurement results.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] Please refer to Figures 1-6 , a module optical test fixture, comprising a module to be tested 1 and a transfer FPC 2, a module FPC 3 is arranged on the module to be tested 1, and the transfer FPC 2 is used for detachably connecting with the module FPC 3;

[0038] The positioning fixture seat 4 has a module positioning groove 5 on its upper surface, and the module positioning groove 5 is in a step shape. A through groove 6 connected to the module positioning groove 5 is formed on the front of the positioning fixture seat 4, and positioning columns 7 are fixedly connected to the four corners of the lower surface of the positioning fixture seat 4.

[0039] Please refer to Figures 1-6, by designing a special fixture made of a module positioning slot 5 and red cushion wood, the sample of the module 1 to be tested is placed in the multi-functional special module positioning slot 5. Since positioning columns 7 corresponding to the positioning holes 9 on the test platform 8 are arranged around the positioning fixture base 4, the red cushion wood fixture is fixed on the test platform 8 through the cooperation of the positioning columns 7 and the positioning holes 9. In this way, when using this fixture and multiple measurement points are required, as the test platform 8 moves by itself, the module 1 to be tested is firmly positioned in the fixture without problems such as sample offset, sliding, and dropping, and it can be accurately positioned and calibrated during equipment debugging, greatly improving the test efficiency;

[0040] Moreover, by designing a soft and relatively long transfer FPC 2 to connect the module FPC 3 on the module 1 to be tested, the problem of difficult connection between the module 1 to be tested and the test fixture caused by the length or shape limit of the module FPC 3 of the module 1 to be tested can be effectively solved. At the same time, when switching the test screen, the placement position of the sample will not be affected, and the adverse impact on the measurement result accuracy can be avoided.

[0041] The module optical test fixture provided in Embodiment 1 is further optimized. Specifically, the positioning fixture base 4 is made of red cushion wood. Such a design is not only light in weight but also strong and durable;

[0042] As Figure 1 and Figure 2 shown, the module positioning slot 5 matches the module 1 to be tested, and the module positioning slot 5 is used to carry and fix the module 1 to be tested;

[0043] The module positioning slot 5 is designed according to the shape of the sample of the module 1 to be tested, so that the module 1 to be tested is stable and reliable after being placed. A groove is dug at the unfolded part of the module FPC 3, so that the module FPC 3 can be flattened and extended out of the positioning fixture base 4 and easily connected to the transfer FPC 2, thus ensuring the flatness of the test sample; the above design effectively solves problems such as product detachment and low stability during the test process;

[0044] As Figure 2 shown, the module FPC 3 passes through the through groove 6 and is fixedly connected with a first connector 10. One end of the transfer FPC 2 is provided with a second connector 11, and the first connector 10 is fixedly connected with the second connector 11.

[0045] Through the above structural design, the transfer FPC 2 is used to connect the test sample and the test fixture. The length and shape of the transfer FPC 2 are designed according to actual needs, and it can be flexibly and quickly connected, and reduce the influence of the actions of adjusting the position of the test fixture and switching the test screen

[0046] during the test process on the stability of the test sample, thereby improving the accuracy of the test results.

[0047] The module optical test fixture provided in Embodiment 1 or 2 is further optimized. AsFigures 1-4 As shown, it further includes a test platform 8. A plurality of positioning holes 9 are formed in the upper surface of the test platform 8. The plurality of positioning holes 9 are distributed in a rectangular array. The positioning posts 7 are matched with the positioning holes 9. The positioning posts 7 and the positioning holes 9 are used to position the fixation between the fixture seat 4 and the test platform 8.

[0048] The module to be tested 1 is fixed on the test platform 8 through the positioning posts 7. Accurate and effective positioning for test point taking can be achieved according to the coordinates, without the need for multiple position adjustments for positioning measurement, and it can further ensure that the test sample does not shake when the test platform moves.

[0049] As Figure 4 shown, the positioning post 7 includes a fixing rod 701. The top end of the fixing rod 701 is fixedly connected to the positioning fixture seat 4. A circular protrusion 702 is fixedly connected to the bottom end of the fixing rod 701. Such a setting enables the circular protrusion 702 to guide when inserted into the positioning hole 9, making it more convenient to use.

[0050] In the further optimization of the module optical test fixture provided in the above embodiments, as Figure 5 and Figure 6 shown, a module cover plate 13 is rotatably connected to the upper surface of the positioning fixture seat 4 through a rotating shaft 12. A test hole 14 is formed in the module cover plate 13. The module cover plate 13 is used to limit the module to be tested 1 in the module positioning groove 5. The rear side of the module cover plate 13 is rotatably connected to the positioning fixture seat 4 through the rotating shaft 12. A first magnet 15 is installed on the lower surface of the front side of the module cover plate 13. A second magnet 16 is installed on the upper surface of the positioning fixture seat 4. The positions of the first magnet 15 and the second magnet 16 correspond to each other.

[0051] With such a setting, after placing the sample of the module to be tested 1 in the multifunctional dedicated module positioning groove 5, closing the module cover plate 13, at this time, the first magnet 15 and the second magnet 16 attract each other, and testing can be carried out through the test hole 14, thereby stably limiting the module to be tested 1 in the module positioning groove 5 and avoiding movement during testing.

[0052] A first elastic soft pad 17 is fixedly connected to the inner bottom wall of the module positioning groove 5. A second elastic soft pad 18 is fixedly connected to the lower surface of the module cover plate 13. A handle 19 is fixedly connected to the front surface of the module cover plate 13. An anti-slip pattern is provided on the outer surface of the handle 19.

[0053] With such a structural design, by setting the first elastic soft pad 17 and the second elastic soft pad 18, after closing the module cover plate 13, the first elastic soft pad 17 and the second elastic soft pad 18 will be compressed, so as to better adapt to the thickness of the module to be tested 1. By setting the handle 19, it is convenient to open the module cover plate 13 to take out the module to be tested 1 after the test is completed.

[0054] The use process of the module optical test fixture provided by the utility model is as follows:

[0055] By designing a special module positioning groove 5 and a jig made of red wood, the sample of the module to be tested 1 is placed in the multifunctional special module positioning groove 5. Since the positioning fixture seat 4 is surrounded by positioning columns 7 corresponding to the positioning holes 9 on the test platform 8, the red wood jig is fixed on the test platform 8 through the positioning columns 7 and the positioning holes 9. In this way, when this jig is used and multiple point measurements are required, as the test platform 8 moves by itself, the module to be tested 1 is firmly positioned in the jig without problems such as sample displacement, sliding and falling. It can also be accurately positioned and calibrated when debugging the equipment, thereby greatly improving the test efficiency. By designing a soft and long adapter FPC2 to connect the module FPC3 on the module to be tested 1, the problem of difficulty in connecting the module to be tested 1 and the test frame due to the length or shape limit of the module FPC3 of the module to be tested 1 can be effectively solved. At the same time, when switching the test screen, it will not affect the placement of the sample, thereby avoiding adverse effects on the accuracy of the measurement results.
