DETAILED DESCRIPTION

[0013] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0014] Example: A pick-and-place fixture for forklift racks with different specifications of materials, such as Figure 1-Figure 3 As shown, it includes a mounting plate 1, which is characterized in that: a connecting seat 2 is provided at the center position of the upper surface of the mounting plate 1, and telescopic cylinder 1 3, telescopic cylinder 2 4, telescopic cylinder 3 5 and telescopic cylinder 4 6 are distributed on the upper surface of the mounting plate 1 around the connecting seat 2, and the telescopic cylinder 1 3, telescopic cylinder 2 4, telescopic cylinder 3 5, telescopic cylinder 4 6 are arranged in a rectangular arrangement, and grabbing cylinder 1 7, grabbing cylinder 2 8, grabbing cylinder 3 9 and grabbing cylinder 4 10 are respectively provided at positions corresponding to telescopic cylinder 1 3, telescopic cylinder 2 4, telescopic cylinder 3 5, and telescopic cylinder 4 6 on the lower surface of the mounting plate 1, and are respectively fixedly connected to the protruding ends of telescopic cylinder 1 3, telescopic cylinder 2 4, telescopic cylinder 3 5, and telescopic cylinder 4 6, the front end of the mounting plate 1 is provided with side grabbing cylinder 11 and side grabbing cylinder 2 12, and the rear end of the mounting plate 1 is provided with two groups of electromagnetic suction 13.

[0015] The telescopic cylinder 1 3 , telescopic cylinder 2 4 , telescopic cylinder 3 5 and telescopic cylinder 4 6 are respectively provided with guide rods 14 around them for increasing the stability of the extension and retraction of the grabbing cylinder 1 7 , grabbing cylinder 2 8 , grabbing cylinder 3 9 and grabbing cylinder 4 10 .

[0016] A distance sensor 15 is provided on the mounting plate 1 between the side grabbing cylinder 1 11 and the side grabbing cylinder 2 12 .

[0017] The guide rod 14 is slidably connected to the mounting plate 1 , and the lower end is fixedly connected to the corresponding grabbing cylinder 1 7 , grabbing cylinder 2 8 , grabbing cylinder 3 9 and grabbing cylinder 4 10 .

[0018] First, the PLC calls the robot program to start the robot operation. It moves to the upper end of the material rack, and the distance sensor 15 detects the distance (the material needs to detect the workpiece height for the first time, and the robot offset distance can be calculated by the offset for the second time). Then, the robot moves to the safe position, the telescopic cylinder 13 extends, the grabbing cylinder 17 opens the grabbing claw, and after the magnetic induction is in place, the robot moves down to the target position, the grabbing cylinder 17 grabs the material 1, and then rises to the safe position, and the telescopic cylinder 1 retracts.

[0019] The material moving robot detects the distance of the material 2, the telescopic cylinder 2 4 extends, the grabbing cylinder 2 8 opens the gripper, and after the magnetic induction is in place, the robot moves down to the target position, the grabbing cylinder 2 8 grabs the material 2 and rises to a safe position, and the telescopic cylinder 2 4 retracts;
