[0046] The working principle of the utility model is as follows:

[0047] Before the operation, first determine the specifications and models of the processed raw materials; then adjust the first baffle 213 in the storage box 212 and the second baffle 224 in the transition transfer plate 223 to the corresponding positions through the adjustment mechanism 214; then adjust the limit block 237 to the corresponding position; finally, load the raw materials into the storage box 212.

[0048] When working, see Fig.16 As shown (the reference numeral A in the figure represents the processing equipment; the reference numeral B in the figure represents the present device), the piston rod of the second cylinder 233 extends out and drives the lifting plate 231 to move upward through the connecting seat 236. At this time, the raw material back in the groove 2311 is lifted; when lifted to the set height, the raw material rolls into the transition transfer plate 223, and then rolls into the temporary raw material placement table 225 through the transition transfer plate 223. The piston rod of the first cylinder 226 extends out to support the raw material. At the same time, the piston rod of the second cylinder 233 contracts, driving the lifting plate 231 to reset, and then the next group of raw materials rolls into the groove 2311; then the articulated arm robot 4 drives the clamping assembly 43 to move to the top of the raw material in the temporary raw material placement table 22. Specifically, one group of finger cylinders 432 moves to the top of the raw material in the temporary raw material placement table 22, and this finger cylinder 432 drives the clamp 433 to clamp the raw material; then the piston rod of the first cylinder 226 contracts, and the articulated arm robot 4 drives the clamping assembly 43 to move toward the processing equipment.

After the finished raw materials on the processing equipment are removed under the drive of the articulated arm robot 4, the articulated arm robot 4 drives the clamping assembly 433 that clamps the raw materials to transfer the materials into the processing equipment; after completion, the articulated arm robot 4 drives the clamping assembly 43 to move toward the workpiece placement module 3, places the processed workpieces in the workpiece placement slot 311 in sequence, and then performs the next round of material picking and loading operations.
