The vacuum suction cup 211 is connected to an external power source. This is prior art and will not be described in detail here. The mounting frame 210 is always oriented towards the base plate 1 and does not rotate with the connecting plate 209. When it is necessary to collect the flexible circuit board, the entire device is moved to the location of the flexible circuit board to be collected, so that the vacuum suction cup 211 is located on the flexible circuit board. The system drives cylinder 203, which in turn moves the movable frame 204. Vacuum suction cup 211 comes into contact with the flexible circuit board and performs adsorption. The system also drives hydraulic cylinder 214, which in turn moves connecting rod 215. The first rotating shaft 205 rotates on the movable frame 204 under the action of connecting rod 215.

It needs to be manually spread out later. To prevent the flexible circuit board from accumulating, the drive motor 308 is activated. 8 can drive the second bevel gear 309 to rotate. The first bevel gear 307 drives the rotating shaft 305 to rotate under the action of the second bevel gear 309. The rotating gear 306 follows the rotating shaft 305 to rotate. Under the meshing action of the rotating gear 306 and the rack 310, the sliding frame 304 can slide on the guide frame 303. The transmission frame 311 follows the sliding frame 304 to slide on the slide groove 302.

[0031] Working principle: When it is necessary to collect and unload flexible circuit boards, the entire device is moved to the location of the flexible circuit board to be unloaded, so that the vacuum suction cup 211 is positioned above the flexible circuit board. The driving cylinder 203 drives the moving frame 204 to move, and the vacuum suction cup 211 comes into contact with the flexible circuit board and performs adsorption.
