Technical Field

[0001] This invention relates to the field of endoscope manufacturing technology, specifically to a method for manufacturing an endoscope module. Background Technology

[0002] An endoscope is a medical diagnostic instrument used to observe lesions and perform surgical treatments within the body's lumens. There are many types, including rigid endoscopes, flexible endoscopes, and electronic endoscopes. Rigid endoscopes are typically made of metal or hard alloys and can visualize larger cavities; flexible endoscopes have a larger bending radius and can be used to visualize smaller cavities; electronic endoscopes convert optical images into electronic signals, which are then transmitted to a television monitor for observation. Endoscopes are widely used in the gastrointestinal, respiratory, and urinary systems and are of great significance for the diagnosis and treatment of diseases.

[0003] To overcome the common problem that the coaxial cable part in the module structure of endoscopes is mostly manually soldered to the PCB board, the wire is too thin and is easy to break during the soldering process and glue fixation, which affects the production efficiency and output.

[0004] Therefore, there is an urgent need for a method to manufacture endoscope modules that can be automated for welding, thereby improving production efficiency and output. Summary of the Invention

[0142] The camera 4011 is equipped with a camera lifting motor 4012, which is used to drive the camera 4011 to lift and lower.

[0143] A telecentric lens 4013 and a ring light source 4014 are arranged sequentially below the camera 4011, and a point light source 4015 is arranged on the side of the telecentric lens 4013; the ring light source 4014 and the point light source 4015 are used to provide light source for the camera 4011 to collect video information through the telecentric lens 4013.

[0144] Camera 4011 is used to capture video information of the product undergoing T-welding process and send it to the controller.

[0145] The controller is used to analyze the position of the weld points on the product based on video information, and drive the welding X-axis 401, welding Y-axis 402 and welding Z-axis 403 to move the welding unit 405 to weld the product.

[0146] As attached Figure 13 As shown, AOI inspection station 5 includes: AOI inspection station body 501, AOI inspection X-axis 502, AOI inspection Y-axis 503, AOI inspection Z-axis 504, and AOI system 505.

The AOI inspection X-axis 502, AOI inspection Y-axis 503 and AOI inspection Z-axis 504 are all connected to the AOI system 505 and are used to drive the AOI system 505 to move along the X-axis, Y-axis and Z-axis directions.

[0148] The AOI system 505 is used to perform AOI inspection on the semi-finished modules in vehicle 2. AOI inspection involves taking an image of the semi-finished module and comparing it with a standard image stored in the AOI system 505 to analyze the similarity and whether it meets preset requirements. If yes, the AOI inspection passes; otherwise, it fails.

[0149] PCB-A6 and PCB-B7 are mounted on carrier 2. The two welding carriers are then conveyed to the designated position, i.e., positioning station 3, via a conveyor belt. The position is then automatically corrected by the photo positioning mechanism 304 and the rotation adjustment device 303. The carrier 2 is then flipped over, and the position of the solder pads is precisely located by the vision system 404. The welding unit 405 is then adjusted to perform welding. Specifically, solder balls are added to the solder ball hopper, and the solder balls are melted by a laser. Then, the solder balls are sprayed onto the designated solder pads by the nozzle 409 to complete the welding. Finally, the components are conveyed to AOI inspection station 5 for AOI inspection.

[0150] S3. Fix the semi-finished module and the head end after applying glue and curing, and then apply glue to the bottom of the head end to cure, thereby obtaining the endoscope module finished product.

[0151] S4. Test the finished endoscope module and package it after passing the test.
