[0025] The workbench 4 has guide rails 6 on both the left and right sides of its top. Sliding sliders 61 are mounted on each guide rail 6, moving back and forth. Each slider 61 has a fixture 62 on its upper part, consisting of a platform and an extension arm. The fixture 62 has a groove containing a second inspection instrument 65 with its probe facing upwards. A transparent plate 63 is laid on top of the fixture 62, with a clamping block and a holding block for holding the endoscope module's gripping part and cable section, respectively. One end of the transparent plate 63 has a notch to allow lens insertion. The inspection probe of the second inspection instrument 65 can scan the endoscope module through the transparent plate 63. The first inspection instrument 56 can perform more complete and detailed inspection of the surface of the endoscope module. The tooling 62 has a transmission connector 64 near the clamping block. The transmission connector 64 is used to connect the control module and imaging module of the endoscope module. The transmission connector 64 is connected to the digital screen 3. Through these designs, the second inspection instrument 65 can accurately inspect the internal structure of the endoscope module. The design of the transparent plate 63, clamping block and holding block ensures the stable fixation of the endoscope module and avoids displacement or damage during the inspection process. The connection between the transmission connector 64 and the digital screen 3 enables the real-time transmission and display of inspection data, further improving the efficiency and accuracy of the inspection.

[0026] The worktable 4 is equipped with a transmission mechanism. Under the action of the transmission mechanism, the two tooling 62 move back and forth alternately. This alternating movement design makes the inspection process more continuous and efficient, avoids production interruptions caused by frequent tooling changes, and significantly improves production efficiency. Through the coordinated work of the above components, the inspection table not only realizes the all-round and multi-angle inspection of the endoscope module, but also greatly improves the accuracy and efficiency of the inspection, ensuring the quality and performance of the endoscope module.

[0027] Among them, such as Figures 1-5 As shown, the transmission mechanism includes a motor 7, a pulley assembly 71, and a connecting plate 72. Two guide grooves are provided on the upper part of the worktable 4 near the two guide rails 6. The pulley assembly 71 is located in the upper part of the worktable 4. The pulley assembly 71 consists of two pulleys and a belt wound around the pulleys. The pulley assembly 71, the guide grooves, and the guide rails 6 are arranged in the same direction. This design ensures that the movement direction of the pulley assembly 71 is consistent with the movement direction of the tooling 62, allowing the tooling 62 to move smoothly along the guide rails 6, thus improving the stability and accuracy of the transmission.

[0028] A motor 7 is vertically installed at the rear of the workbench 4. One pulley of a pulley set 71 is connected with the output shaft of the motor 7, and the pulley set 71 is driven by the motor 7. The motor 7 serves as a power source to provide stable driving force, ensuring smooth operation of the pulley set 71 and driving the movement of the tooling 62. The forward and reverse rotation control of the motor 7 enables the pulley set 71 to rotate clockwise and counterclockwise alternately, realizing the reciprocating movement of the tooling 62 and improving work efficiency and flexibility.

[0029] The pulley set 71 is arranged in the area between the two guide grooves. The tooling 62 is provided with a connecting plate 72, and the connecting plate 72 is inserted into the same side of the sliding groove and connected with one side of the pulley set 71. The connecting plate 72 transmits the movement of the pulley set 71 to the tooling 62, enabling the tooling 62 to move smoothly on the guide rail 6. This connection mode not only ensures the reliability of transmission, but also reduces friction and wear, prolonging the service life of the equipment.

[0030] The initial positions of the two toolings 62 are arranged in front of and behind each other. The motor 7 intermittently performs forward and reverse rotation, thereby driving the pulley set 71 to rotate clockwise and counterclockwise alternately, and the positions of the two toolings 62 are alternated. In this way, the two toolings 62 can realize orderly reciprocating movement on the workbench, ensuring that each tooling 62 can reach the detection position in turn, improving the continuity and automation of detection. This alternating movement design can also make full use of the space of the workbench 4, improving production efficiency.

[0031] During detection, the endoscope module is placed on a transparent plate 63, and a transmission connector 64 is connected with the plug interface on the endoscope module. The motor 7 is controlled to rotate, and the pulley set 71 drives the endoscope module on the tooling 62 into the working area of the detector 56. Through the transmission connector of the endoscope module and the preset program in the digital screen 3, the lens of the endoscope module is controlled to perform function and imaging test, and the detection process and results are fed back and recorded in real time on the digital screen, thereby realizing high-precision appearance detection and function test, improving the accuracy and reliability of detection, simplifying the operation process, improving the detection efficiency, ensuring the quality and performance of the endoscope module, and realizing continuous and efficient material supply through the alternating movement of the two toolings 62 driven by the transmission mechanism.

[0032] In the embodiment 1, the endoscope module is placed on the transparent plate 63, and the transmission connector 64 is connected with the plug interface on the endoscope module. The motor 7 is controlled to rotate, and the pulley set 71 drives the endoscope module on the tooling 62 into the working area of the detector 56. Through the transmission connector of the endoscope module and the preset program in the digital screen 3, the lens of the endoscope module is controlled to perform function and imaging test, and the detection process and results are fed back and recorded in real time on the digital screen, thereby realizing high-precision appearance detection and function test, improving the accuracy and reliability of detection, simplifying the operation process, improving the detection efficiency, ensuring the quality and performance of the endoscope module, and realizing continuous and efficient material supply through the alternating movement of the two toolings 62 driven by the transmission mechanism. Figures 4-5As shown, the test box 8 is arranged at the end of the extension arm of the tool 62 away from the platform. The test box 8 is hollow and closed inside, and forms a low-light area compared to the outside. The front of the test box 8 is provided with a slot allowing the endoscope module lens to pass in. During testing, the lens of the endoscope module is controlled by the transmission joint 64 to pass into the test box 8, so as to test the illumination module of the endoscope module, and ensure the illumination effect and stability of the illumination module under low light conditions, thereby improving the reliability and adaptability of the endoscope module in actual application.

[0033] As shown in Figures 1-3 As shown, the detector three 9 is arranged on one side of the detector one 56. The detector one 56 and the detector three 9 are arranged in the same direction and rotate synchronously with the driving of the rotary driving part 55. Through the synchronous rotation design, the detector three 9 can perform additional detection on the endoscope module at different angles. For example, the detector three 9 is arranged as an infrared detector. While the endoscope module is performing appearance detection, the detector three 9 performs internal scanning to comprehensively check the internal circuit board, connection line and key components of the endoscope module, so as to ensure the integrity of the internal structure and the normal operation of the function, thereby improving the comprehensiveness and accuracy of the detection, effectively avoiding the use risk caused by internal failure, or detecting the environmental parameters such as temperature and humidity through the detector three 9, further improving the comprehensiveness and accuracy of the detection.

[0034] In addition, as shown in Figure 1 and Figure 6 As shown, the material frame 10 and the material rack 101 are arranged. The front of the base 1 is provided with two material frames 10. The material frame 10 is provided with a plurality of material racks 101 at intervals. The material rack 101 is used for placing the endoscope module. The two material frames 10 are respectively used for placing the qualified and unqualified endoscope modules after testing. Through the classified storage design, the operator can quickly distinguish the qualified and unqualified products, which is convenient for subsequent processing and quality control, improves the production efficiency and management level, and makes the endoscope module stable during storage, avoiding damage caused by improper stacking.

The precise control of the hydraulic cylinder 11 also ensures the stable lifting of the workbench 4, and improves the stability and reliability of the detection.
