The XY-axis displacement assembly 200 is located below the support frame 110. The adjusting assembly 300 is arranged on the XY-axis displacement assembly 200, and the XY-axis displacement assembly 200 is used to drive the adjusting assembly 300 to reciprocatingly displace in X-axis direction and Y-axis direction. The rotating assembly 400 is connected with the adjusting assembly 300, and the adjusting assembly 300 is used to adjust the position of the rotating assembly 400. A loading jig is installed on the rotating assembly 400. When the product to be inspected is placed on the loading jig, the XY-axis displacement assembly 200, the adjusting assembly 300 and the rotating assembly 400 are respectively used to drive the loading jig to move, so that the visual inspection module 120 can visually inspect the product on the loading jig at multiple positions.
[0023] It should be noted that the Z-axis lifting module 130 is used to adjust the distance between the visual inspection module 120 and the loading jig, that is, the distance between the visual inspection module 120 and the loading jig is adjusted through the Z-axis lifting module 130, so that the visual inspection module 120 can be ensured to be at the best shooting position, thereby ensuring the accuracy of the shooting inspection. Further, the XY-axis displacement assembly 200, the adjusting assembly 300 and the rotating assembly 400 are all used to drive the loading jig to move, thereby changing the different inspection positions of the product on the loading jig, so as to realize the inspection of the product on the loading jig at different positions, instead of the existing frequent clamping and turning of the product by artificial or mechanical hand, thereby improving the inspection efficiency and ensuring the inspection accuracy. Specifically, when the product is placed on the loading jig, the XY-axis displacement assembly 200 is used to drive the loading jig to move to the lower side of the visual inspection module 120, and then the position of the visual inspection module 120 is adjusted through the Z-axis lifting module 130, so that the visual inspection module 120 can be ensured to be at the best shooting position. When the shooting inspection of a certain position on the product is completed, the position of the loading jig can be changed through the adjusting assembly 300 and the XY-axis displacement assembly 200. Especially for the product which cannot be completely shot at one time or requires high shooting inspection, the adjusting assembly 300 and the XY-axis displacement assembly 200 are very important for adjusting and changing the shooting position of the product.

That is, when the adjusting driving module 320 drives the lower lifting inclined slide block 330 to move, the upper lifting inclined slide block 340 simultaneously realizes inclined lifting movement. In this way, the position of the product can be moved, especially for the product with an inclined surface. Through the adjusting assembly 300, it can be ensured that the visual detection module 120 can completely shoot the inclined surface of the product, thereby ensuring the shooting accuracy of each shooting position and improving the accuracy of the detection result.
