[0062] The placement table 14 is provided with a good product area 1401 and a defective product area 1402;

[0063] The first direction X and the second direction Y are perpendicular to each other.

[0064] It should be noted that the flexible circuit board 15 is placed on the loading table 2, the first moving device 3 moves the flexible circuit board 15 to the first detection device 4, the first visual detection and marking device 11 detects and marks defects on the flexible circuit board 15 on the first detection device 4, and the first moving device 3 then moves the flexible circuit board 15 from the first detection device 4 to the placement table 14, and good products are placed in the good product area 1401, and defective products are placed in the defective product area 1402. Therefore, when the staff re-inspects the flexible circuit board, they only need to check the marking position of the flexible circuit board 15 in the defective product area 1402, and there is no need to inspect the flexible circuit board 15 as a whole to determine whether the flexible circuit board 15 meets the good product standard, which improves the efficiency of manual re-inspection of the flexible circuit board 15 and can improve the production efficiency of the flexible circuit board 15.

[0065] See also Figure 1 In a more specific embodiment, the rack 1 further includes a base 101 , and the panel 102 is mounted on the base 101 .

[0073] It should be noted that, in the initial state, the loading lifting mechanism 202 is raised, and the loading platen 201 is lifted to the highest point, and the flexible circuit board 15 is placed on the loading platen 201. The movable mounting plate 3021 of the adsorption device 302 moves along the first horizontal movable slide rail 301 to the top of the loading platen 201, and the adsorption lifting mechanism 3022 is driven to drive the connected suction cup to descend, until the suction cup sucks the flexible circuit board 15 on the loading platen 201 and then drives the suction cup to rise. While the suction cup sucks the flexible circuit board 15, the loading lifting mechanism 202 drives the connected loading platen 201 to descend, ensuring that the flexible circuit board 15 is separated from the loading platen 201;

[0074] The adsorption device 302 adsorbs the flexible circuit board 15, and after the mobile mounting plate 3021 moves along the first horizontal movable slide rail 301 to the top of the first detection device 4, the adsorption lifting mechanism 3022 is driven to drive the connected suction cup and the flexible circuit board 15 adsorbed by the suction cup to descend.

[0081] A telescopic rod 204 is connected between the loading base plate 203 and the loading platform 201, so that when the loading lifting mechanism 202 lifts the loading platform 201, the telescopic rod 204 is extended; when the loading lifting mechanism 202 drives the loading platform 201 to descend, the telescopic rod 204 is shortened, and the telescopic rod 204 ensures the stability of the position between the loading platform 201 and the loading base plate 203;

[0082] In a more specific embodiment, the loading platform 201 is a polygon, the number of telescopic rods 204 is the same as the number of sides of the loading platform 201, and each telescopic rod 204 is connected to each corner of the loading platform 201 to ensure the stability of the loading platform 201 when rising or falling.
