[0035] Working principle: When in use, the metal parts are manually placed in the storage slot 16 on the discharge tray 8. One of the two discharge trays 8 is used for manually placing metal parts and the other is used for taking materials. The reciprocating translation mechanism 7 drives the rectangular frame 6 to reciprocate, and the rectangular frame 6 drives the two discharge trays 8 to move back and forth, thereby ensuring continuous loading and taking of metal parts; the taking head 10 is moved to the specified position by the head moving mechanism 11, the metal parts are clamped by the taking head 10, and the metal parts are positioned and supported by the supporting and positioning mechanism 9, so that the metal parts can be assembled in conjunction with other processes; the roller 2 is used to facilitate the movement of the whole to the specified position, and the foot cup 3 can support the whole.

[0036] The operating principle of the reciprocating translation mechanism 7 is: the first servo motor 71 drives the active pulley 72 to rotate, and the active pulley 72 drives the driven pulley 74 to rotate through the transmission belt 75. During the transmission process, the transmission belt 75 drives the connecting block 76 to move, and the connecting block 76 drives the rectangular frame 6 to move. Therefore, the forward and reverse rotation of the first servo motor 71 can drive the rectangular frame 6 to reciprocate.

[0037] The operating principle of the head moving mechanism 11 is: the second servo motor 112 drives the screw rod 113 to rotate, and the screw rod 113 drives the moving seat 114 to move through the threaded transmission between the screw rod 113 and the moving seat 114, so as to realize the translation of the material picking head 10, and the first mounting plate 116 is driven to move by the piston rod of the first double-axis cylinder 115, so as to realize the vertical movement of the material picking head 10.
