There is a release area 25 between the two electromagnetic columns 24 and the electromagnetic columns 24 .

The release area 25 is not provided with an electromagnetic column 24, so that when the holder 28 is in the position of the electromagnetic column 24, it can be attracted by the electromagnetic column 24, move in the active area 26, and compress downward, and the retaining deformation arm 27 is subjected to external force and deforms. The workpiece 3 in the placement groove 4 is thereby clamped. And when the holder 28 rotated to the release area 25, the electromagnetic column 24 did not appear at the lower end of the holder 28 at this moment, so it would not be attracted by magnetic force, so that the attraction piece 29 on the holder 28 was under the action of the deformation arm 27 Restore.

In addition, an electromagnetic column 24 can also be added at the release area 25. The magnetic force direction of the electromagnetic column 24 is the same as that of the magnetic force direction at the lower end of the magnet 30 inside the attracting block 29, so as to achieve the effect of repelling each other in the same direction, and the auxiliary deformation arm 27 will attract Block 29 is restored.

The rotating disk 11 is provided with placement slots 4 corresponding to the position of the holder 28 , and the placement slots 4 are located at both ends of the holder 28 . When the electromagnet 22 is energized to generate a magnetic force, it attracts the magnet 30 in the middle of the holder 28 , so that the attracting block 29 moves down and attaches to the sheet portion 31 .

The bottom of the rotating disk 11 is provided with an annular groove 32 for accommodating the electromagnet 22 , in which the electromagnet column 24 can be kept as close as possible to the sheet part 31 , which is beneficial to better attract the holder 28 .

The rotary disk 11 is composed of an inner ring 33 and an outer ring 34 , a clamping area 35 is formed between the inner ring 33 and the outer ring 34 , and the placement groove 4 is located on the inner ring 33 and the outer ring 34 . A thin piece 31 is disposed in the middle of the clamping area 35 , the thin piece 31 is located at the upper end of the annular groove 32 , and the holder 28 is located at the thin piece 31 .

The holder 28 moves downward under force to clamp the workpiece 3 in the slots 4 at both ends. When the external force disappears, the holder 28 returns to its original shape. Holder 28 is made up of suction block 29 and symmetrical deformation arm 27, support portion 36 and installation portion 37, forms the active area 26 that attracts block 29 displacements between symmetrical installation portion 37, and installation portion 37 is positioned at the lower end of support portion 36, The deformation arm 27 is located on both sides of the suction block 29 , the deformation arm 27 is located at the upper end of the support portion 36 , and the rotating disk 11 is provided with a mounting groove 38 , and the holder 28 is inserted into the mounting groove 38 through the mounting portion 37 .

Moreover, the distance between the electromagnetic columns 24 can ensure that the holder 28 is still attracted by the electromagnetic columns 24 when the rotating disk 11 is rotating. After crossing an electromagnetic column 24, it will immediately reach the next electromagnetic column 24, so that the magnetic force will not disappear. Only when the magnetic force reaches the release zone 25 will it disappear.

As shown in FIG. 19 , when the electromagnetic column 24 at the lower end of the holder 28 is no longer energized, the attracting block 29 is pushed in the P direction by the elastic force of the deformable arm 27 , keeping the deformable arm 27 in a bent state to form a straight line. So that the holder 28 no longer clamps the workpiece 3, the workpiece 3 can be clamped to the processing place by the manipulator.
