[0019] T-shaped grooves 16 are provided at the upper and lower ends of the transverse connecting rod 11 and the vertical connecting rod 10. Locking plates 9 are also placed in the T-shaped grooves 16 to facilitate the relative fixation between the transverse connecting rod 11, the vertical connecting rod 10 and the suction cup 14. When the position needs to be adjusted according to the product, it is also convenient to disassemble and adjust the position distance between the transverse connecting rod 11, the vertical connecting rod 10 and the suction cup 14. A suction cup fixing plate 13 is also placed on the lower end side of the vertical connecting rod 10. The suction cup 14 is fixedly installed on the other side of the suction cup fixing plate 13. A bolt 5 is also provided on the suction cup fixing plate 13. The bolt 5 penetrates the suction cup fixing plate 13 and is threadedly connected to the locking plate 9. When the suction cup 14 needs to be adjusted at the lower end side of the vertical connecting rod 10, the bolt 5 can be unscrewed to move the suction cup 14. When it moves to the specified position, the bolt 5 can be re-tightened to lock the suction cup fixing plate 13 and the suction cup 14. Similarly, the fixing The bottom of the seat 15 is also provided with a bolt 5, and a locking piece 9 is also placed inside the T-shaped slot 16 at the bottom of the transverse connecting rod 11.

At the same time, two bolts 5 are also provided on each connecting seat 8. A locking piece 9 is also placed in the T-shaped slot 16 on the upper side of the vertical connecting rod 10. The left and right positions of the vertical connecting rod 10 relative to the transverse connecting rod 11 can be adjusted by tightening the locking piece 9 by the bolt 5 on the connecting seat 8. The rotating block 7 is an "L"-shaped structure, and a connecting head 6 is also fixed on the lower end side of the telescopic rod 2.

After the suction cup 14 contacts the surface of the product, the air pipe 3 sucks air to drive the suction cup 14 to adsorb the product. After adsorption, the mechanical main arm 1 moves to bring the suction cup 14 and the product out of the injection molding machine and transfer them to the top of the conveyor belt. When reaching the top of the conveyor belt, the bottom end of the telescopic rod 2 returns upward to drive the rotating block 7 to rotate on the fixed shaft 4, and the rotation drives the fixed seat 15 to rotate at the same time. The rotation of the fixed seat 15 drives the transverse connecting rod 11 and the two vertical connecting rods 10 to rotate together. Figure 1 It is a schematic diagram after rotation, and finally the air pipe 3 stops sucking air so that the product sucked by the suction cup 14 falls onto the transmission belt and is transferred to the next process.

[0021] When different products need to be adsorbed, the size and specifications of each product are slightly different. Therefore, it is necessary to adjust the position of the transverse connecting rod 11, the two vertical connecting rods 10 and each suction cup 14. When adjusting, you only need to loosen the bolt 5, and the locking plate 9 can move in the T-shaped slide groove 16 in the transverse connecting rod 11 and the vertical connecting rod 10. When moving to the specified position, re-tighten the bolt 5, and the bolt 5 can be locked to re-fix the locking plate 9. It is very suitable for companies with a large number of product categories.
