[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the quick-change unit 1 of the present invention is connected to the connecting component 2, the mounting plate 3 is connected and fixed to the connecting component 2 by bolts, three vacuum suction cups 6 and two bearing mounting seats 4 are installed on the mounting plate 3, linear bearings 11 are respectively installed in the two bearing mounting seats 4, two guide rods 8 are installed in the linear bearings 11, and the two ends of the guide rods 8 are respectively connected to the magnetic cylinder mounting plate 10 and the limit plate 5, a compression spring 7 is installed between the bearing mounting seat 4 and the magnetic cylinder mounting plate 10, the compression spring 7 is sleeved on the guide rod 8, the magnetic cylinder 9 is fixed on the magnetic cylinder mounting plate 10, and the magnetic cylinder 9 is installed at 90 degrees to the vacuum suction cup 6.

[0015] The quick-change unit 1 is used to connect the manipulator and the gripper, and can switch the gripper quickly and conveniently. The quick-change unit 1 consists of a common side 12 and a switching side 13; the common side 12 is provided with a rotating shaft 14 and a locking hook 16 on both sides, a handle 17 is fixed on the rotating shaft 14 and connected to the locking hook 16, a positioning hole 18 is provided inside the common side 12, a positioning shaft 19 of the switching side 13 is inserted into the positioning hole 18, and is fixed in the switching side 13 by the locking shafts 15 on both sides of the switching side 13. During operation, insert the positioning shaft 19 into the positioning hole 18, turn the handle 17 clockwise, and the handle 17 will rotate around the rotating shaft 14, driving the locking hook 16 to rotate clockwise until the locking hook 16 is engaged with the locking shaft 15, so that the common side 12 and the switching side 13 are locked to form a self-locking state, thereby connecting the common side 12 and the switching side 13; when switching, turn the handle 17 counterclockwise, the locking hook 16 will disengage from the locking shaft 15, pull the positioning shaft 19 downward, and the switching side 13 can be quickly disengaged from the common side 12.

[0016] The vacuum suction cup 6 is an accordion-type vacuum suction cup with a spring 20, a telescopic guide rod 21, an accordion cover suction head 22, a nut 23, and a screw 24. The vacuum suction cup 6 is fixed to the mounting plate 3 by two nuts 23 and a screw 24; the three-way vacuum generator controls the three vacuum suction cups 6 separately to adapt to workpieces of different shapes and sizes. The spring 20, the telescopic guide rod 21 and the accordion cover suction head 22 of the vacuum suction cup 6 can ensure that the vacuum suction cup 6 floats up and down so as to grab stacked workpieces of different heights.

[0017] The magnetic cylinder 9 is installed at 90 degrees to the vacuum suction cup 6, and the compression spring 7 can ensure that the magnetic cylinder 9 can float along the compression spring 7. When the vacuum suction cup 6 cannot meet the grasping conditions of the workpiece, the magnetic cylinder 9 can be used to grasp, which greatly improves the versatility of the flexible clamp.
