The cooperation between above-mentioned subassembly get the material subassembly and snatch the material spare after, at the removal in-process, the rotational position of material spare can be changed to the rotating assembly on the Z axle, the displacement subassembly can change the shift position of material spare on the Y axle to satisfy the dual requirement to material spare position, design optimization.

As shown in fig. 1, the material taking assembly includes four bodies 1 and four adsorbing members 2, which are disposed in one-to-one correspondence with the four bodies 1. Four body 1 sets up along Y axle direction interval, preferably, four the length that body 1 extended on the X axle is crescent along Y axle positive direction to be used for cooperating foretell displacement subassembly can be in proper order to body 1 promotes. Adsorb 2 along the Z axle direction and wear to establish on the body 1, adsorb 2 optional suction nozzle spare commonly used, its lower extreme is used for adsorbing the material spare fixedly to can convey the material spare.

In the present embodiment, as shown in fig. 2 and 3, the guide assembly includes two guide members 3 extending along the Y-axis direction, and preferably, the guide members 3 may be guide rods extending along the Y-axis direction and arranged in parallel in a horizontal plane, and two end portions of the guide rods are fixedly arranged on the outer bracket. Foretell four the equal sliding sleeve of body 1 is established two on the guide bar, in order to guarantee the gliding accuracy nature of body 1 along Y axle direction also through mechanical spacing mode, the cooperation rotary mechanism can realize right it rotates to adsorb piece 2.

In this embodiment, the rotating assembly comprises four rotating arms 4 which are positioned at the rear side of the material taking assembly and in the horizontal plane, and rotating columns 5 which are fixedly arranged on an external support and are arranged corresponding to the four rotating arms 4 one to one. The rotating arm 4 is provided with a sliding groove 9 extending along the length direction of the rotating arm, and a side wall forming the sliding groove 9 can be abutted against the rotating column 5. Preferably, the free end of the rotating arm 4 is fixedly arranged with the upper end of the adsorbing member 2. In the above arrangement mode, due to the position limitation of the limit column on the rotating arm 4 and the position limitation of the guide rod on the body 1, when the rotating arm 4 rotates in the horizontal plane, the length of the chute 9 can compensate the limited rotating length of the rotating arm 4, so that the rotating arm 4 can drive the adsorption piece 2 to rotate around the Z axis on the basis that the body 1 is along the Y axis direction, and the material piece is adjusted to a required position.
