The housing 300 is spaced above the conveyor belt 200 and is located above the inspection station 200A. A long groove 320 is provided on the side of the housing 300 facing the conveyor belt 200; the first guide rail 400 is fixed at both ends of the long groove 320, and the extending direction of the first guide rail 400 is the same as the conveying direction of the conveyor belt 200; both ends of the second guide rail 500 are respectively slidably connected to the two first guide rails 400, the second guide rail 500 is perpendicular to the first guide rail 400, and a mounting seat 510 is slidably connected to the second guide rail 500; the camera 600 is installed on the mounting seat 510, and the shooting direction of the camera 600 faces the upper surface of the conveyor belt 200.

[0030] In actual use, the circuit board to be inspected is placed on the conveyor belt 200 of the rack 100. Specifically, it is first placed on the inspection station 200B, and then enters the inspection station 200A along with the transportation of the conveyor belt 200. At this time, the circuit board is located below the housing 300. At this time, the camera 600 is turned on, the second guide rail 500 slides along the first guide rail 400, and the mounting seat 510 slides along the second guide rail 500, so that the camera 600 can move in the area of the entire inspection station 200B and photograph the entire circuit board for the user to repair the circuit board. Finally, the circuit board is transported to the recycling station 200C through the conveyor belt 200, and the repaired circuit board is recycled manually or by a manipulator. Among them, the housing 300 wraps the first guide rail 400, the second guide rail 500 and the mounting seat 510, and external dust is not easy to enter the above structures.

[0031] In summary, using the housing 300 to wrap the lens can prevent the sliding mechanism from accumulating a large amount of dust and improve the smoothness of movement; using the transportation of the conveyor belt 200 facilitates the user to load and unload materials while detecting, improving efficiency.

[0032] Preferably, referring to Figure 1 , the second connecting column 120 is a telescopic column, and the second connecting column 120 can be telescoped so that the second connecting column 120 is higher than the first connecting column 110 or at the same height as the second connecting column 120. The front end of the conveyor belt 200 is rotatably connected to the upper end of the first connecting column 110, and the rear end of the conveyor belt 200 is rotatably connected to the upper end of the second connecting column 120. By the telescopic second connecting column 120, the conveyor belt 200 can be tilted to facilitate the user to directly visually inspect the circuit board.

[0033] Furthermore, in some embodiments, referring to Figure 2 , there are three mounting seats 510. The three mounting seats 510 are arranged along the length direction of the second guide rail 500. The mounting seat 510 in the middle is connected with a telescopic rod 511, and the end of the telescopic rod 511 is fixedly connected to the top of the camera 600. Swing rods 512 are respectively arranged between the mounting seats 510 on both sides and both sides of the camera 600. One end of the swing rod 512 is rotatably connected to the mounting seat 510, and the other end is rotatably connected to the camera 600. By sliding the mounting seats 510 on both sides and cooperating with the swing rods 512 and the telescopic rod 511 with variable length, the distance between the camera 600 and the circuit board can be adjusted. Among them, the distance between adjacent two mounting seats 510 is equal, and the lengths of the two swing rods 512 are the same. Using the equal-length swing rods 512 can ensure the stability of the lifting of the camera 600. Connecting seats 513 are arranged on the mounting seats 510 on both sides, and the end of the swing rod is rotatably connected to the connecting seat 513.

[0034] In some embodiments, a plurality of positioning grooves 210 for placing circuit boards are provided on the conveyor belt 200, and the plurality of positioning grooves 210 are arranged at intervals along the conveying direction of the conveyor belt 200. Among them, the conveyor belt 200 moves so that the positioning grooves 210 can be moved to the to-be-inspected station 200B, the inspection station 200A or the recycling station 200C. The shape of the positioning groove 210 matches that of the circuit board. Specifically, in some embodiments, referring to Figure 3 , a plurality of groups of "L"-shaped limiting blocks 211 are provided on the conveyor belt 200. Each group of limiting blocks 211 has four, and the recessed sides of the four limiting blocks 211 are arranged opposite to each other to form the above-mentioned positioning groove 210. In actual use, the plurality of limiting blocks 211 can cooperate to restrict the position of the circuit board.

[0035] Specifically, the positioning groove 210 can also be composed of three limiting edges. One of the limiting edges is perpendicular to the conveying direction of the conveyor belt 200, and the other two limiting edges are respectively fixed at both ends of the limiting edge perpendicular to the conveying direction, and one side of the positioning groove 210 is open. The open side of the positioning groove 210 is located on the side of the positioning groove 210 close to the second connecting column 120, which is convenient for placing the circuit board. At the same time, when the conveyor belt 200 is inclined, the limiting edges can be used to restrict the position of the circuit board to prevent the circuit board from falling.
