Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a test fixture for an LED module. Background Art
[0002] An LED module is a product formed by arranging a certain number of light-emitting diodes in a regular pattern, encapsulating them together, and adding some waterproof treatments.
[0003] After the production of the LED module is completed, in order to prevent the situation of non-conduction or insufficient brightness between the light-emitting diodes, it is necessary to conduct a power-on test on the finished product. During the test process, a workbench is generally set on one side of the assembly line. Workers take the finished LED module from the assembly line and detect it through a test fixture. After successful detection, it is placed on the next assembly line and transferred to the next process, while those that fail the detection will be removed. Currently, the test fixtures for common LDE modules have relatively single functions. Most of them have different detection connectors connected to the test assembly. During the detection process, workers insert the connectors into the module, and after adjusting the power of the connectors, observe whether the module can light up normally and the brightness level. Such a method has certain drawbacks. For example, the models of the test connectors used for different specifications of modules are different, and frequent replacement of the connectors will delay the detection efficiency. At the same time, it may lead to the wrong use of the connectors when not paying attention. And the traditional method requires workers to hold the LED module with one hand and complete the plugging and unplugging operation of the connectors with the other hand. Such a method may cause workers to be unable to accurately insert the connectors, resulting in wear at the connector and module interface positions, affecting the product quality. At the same time, when facing some larger-sized modules, single-handed operation cannot maintain the stability of the module, and it is easy to cause the module to fall and be damaged.
[0004] Therefore, it is necessary to provide a new test fixture for an LED module to solve the above technical problems. Summary of the Utility Model

[0031] The working principle of the LED module test fixture provided by the utility model is as follows:
[0032] During the finished product inspection process of the LED module, first, after the staff member contacts the limit of the closing plate 2, the closing plate 2 can be pulled horizontally. The horizontal movement of the closing plate 2 will drive the horizontal movement of the carrier plate 201, thereby taking out the vertical rod 3, the rotating cylinder 4, and the three side plates 5 from the workbench 1. After taking them out, the staff can install the test connector 11. During the installation process, the staff needs to pull up the steering plate 14, so that the steering plate 14 moves out of the first clamping hole 9 and then rotates, and rotates the steering plate 14 and the inserted column 15 to the outside of the wing plate 8 (as Figure 4 shown). Subsequently, the test connector 11 and the fixed seat 10 are horizontally inserted into the mounting seat 7. The fixed seat 10 is exactly located below the two wing plates 8. After aligning the first clamping hole 9 with the second clamping hole 12, the steering plate 14 can be pulled up again. Pulling up the steering plate 14 will compress the compression spring, so that the compression spring is in a compressed energy storage state. After rotating the steering plate 14 to align with the first clamping hole 9, release the steering plate 14. Under the reset effect of the compression spring, the inserted column 15 moves downward through the corresponding first clamping hole 9 and the second clamping hole 12, thereby completing the positioning of the fixed seat 10 and the test connector 11. The installation of the remaining two test connectors 11 is completed in the above manner. Subsequently, the closing plate 2 is pushed into the workbench 1 again and the positioning of the closing plate 2 is completed.
[0033] After the above is completed, the detection operation of the LDE module can be carried out. During the detection process, the staff can pick up the LDE module with both hands, align the interface of the LDE module with the test connector 11 protruding from the top of the workbench 1 and then slowly put it in, so that the test connector 11 is inserted into the socket, thereby completing the power-on of the module, and the module is detected by observing the brightness of the LED module, etc.
[0034] When facing the interfaces of different models of LDE modules, the staff can horizontally pull out the pin rod 401, thereby releasing the limiting effect between the vertical rod 3 and the rotating cylinder 4. The staff can press down the rotating cylinder 4, so that the rotating cylinder 4 moves downward under the force. At the same time, the upper ring plate 16 will also move downward and compress the spring 19, so that the spring 19 is in a compressed energy storage state, and the three side plates 5 will also move downward. When the positioning blocks 6 at the tops of the three side plates 5 move out of the three corresponding clamping ports 102, at this time the staff can rotate the rotating cylinder 4 (the setting of the connecting ring 17 enables the rotating cylinder 4 to complete the downward pressure in the vertical direction and the rotation in the horizontal direction), thereby changing the angles of the three side plates 5, and further making the test connectors 11 of different models located below the rectangular opening. After the adjustment is completed, only need to release the rotating cylinder 4, and under the reset effect of the spring 19, the rotating cylinder 4 will move upward. At this time, the adjusted test connector 11 will extend above the workbench 1 through the rectangular opening, and the remaining two test connectors 11 will rotate into the accommodation groove 21 on one side.
[0035] Compared with the related art, the test fixture for the LED module provided by the present utility model has the following beneficial effects:
[0036] The present utility model provides a test fixture for an LED module. Through the clamping mechanism of the present application, the installation and fixation of the test connector 11 can be quickly completed, and three test connectors 11 can be fixed at one time. During the work process, the staff can quickly change test connectors 11 of different models by pressing down and rotating the rotating cylinder 4, so as to meet the detection operations of LED modules of different specifications. The whole process is not only simple and convenient, and the operation is fast. At the same time, during the detection, the staff can hold the module with both hands, improving the detection stability and to a certain extent improving the efficiency of the detection work.
