The test cylinder 62 drives the test motion plate 63 to move in the front-back direction. Three test probe mounting boxes 64 and test probes 65 for test processing are mounted sequentially from left to right on the rear side of the test motion plate 63.

[0062] The test probe mounting box 64 and test probe 65, as well as the test structure and test principle of product 11, are all conventional technologies in the field.

[0063] like Figure 7 The side-pressure assembly 7 mainly includes a side-pressure stand 71, a side-pressure cylinder 72, and side-pressure blocks 74. The side-pressure stand 71 is installed on the working platform 1 behind the linear conveyor module 2. The side-pressure cylinder 72 is installed on the top of the side-pressure stand 71. The side-pressure cylinder 72 drives the side-pressure moving plate 73 to move in the front-back direction. Three side-pressure blocks 74 are installed sequentially from left to right on the front side of the side-pressure moving plate 73. A side-pressure contact 75 is designed on the front side of each side-pressure block 74. The side-pressure contact 75 performs side-pressure treatment on the rear side of the product 11.

[0064] like Figure 8 The vision inspection component 8 mainly includes a vision inspection cylinder module 81 and a camera 84. The vision inspection cylinder module 81 is installed on the work platform 1 on the front and rear sides of the linear conveyor module 2. The vision inspection cylinder module 81 drives the vision inspection motion plate 82 to move in the left and right directions. A camera 84 for visual inspection of the product 11 after testing is installed on the vision inspection motion plate 82 through a camera mounting bracket 83.

[0065] The aforementioned vision inspection cylinder module 81 can be a cylinder-driven linear module or a linear motor module, etc.

[0066] like Figure 9 The light source assembly 9 mainly includes a light source stand 92, a light source cover 94, and a light source 95. The bottom of the light source stand 92 is fixedly mounted on the work platform 1 via a light source base 91, and the top of the light source stand 92 is mounted on the light source cover 94 via a light source mounting seat 93. The light source 95 is installed inside the light source cover 94.

[0067] The light source cover 94 is rotatably mounted on the light source bracket 92 via a rotating shaft structure on the light source mounting base 93. The light source cover 94 is also slidably mounted on the light source bracket 92 along the vertical direction. That is, a sliding groove distributed along the vertical direction is opened on the light source bracket 92, and the slider on the light source mounting base 93 is slidably mounted in the sliding groove and can be locked by bolts or the like.

[0068] A brief description of the working process of this embodiment:

[0069] The products 11 to be processed are located in the three fixture slots 34 within the fixture 10. Initially, the receiving assembly 3 is at the lowest position. Then, the fixture 10 is placed in the fixture slots 34 on the receiving platform 33 by hand or a robotic arm. The receiving platform 33 then rises to the highest position. At this time, the straightening cylinder 43 drives the straightening plate 44 to move backward and performs front-side pressure processing on the product 11 through the straightening contact 45 to achieve the straightening purpose. After straightening is completed, the straightening plate 44 is reset, and the fixture 10 is transferred to the linear conveyor module 2 on the right side by manual or automatic means.

[0070] Two sets of test components 6 are designed on the working platform 1 outside the linear conveyor module 2. During the test, the linear conveyor module 2 stops transmission. First, the upper pressure block 54 of the upper pressure component 5 presses the top of the product 11. Then, the side pressure block 74 of the side pressure component 7 presses the rear side of the product 11. After that, the test probe 65 of the test component 6 tests the test part on the front side of the product.

[0071] After the test, fixture 10 continues to flow to the right. During this process, the camera 84 of the vision inspection component 8 performs appearance inspection on the tested product 11. The linear conveyor module 2 stops moving when fixture 10 reaches the inspection station. After inspection, fixture 10 continues to flow to the receiving component 3 on the right. This process is the reverse of the initial loading process, thus completing the unloading process of fixture 10.
