[0024] Specifically, as Figure 1 , Figure 2 and Figure 3As shown, the second servo motor 15 is started to drive the worm 14 to rotate, which can rotate the worm gear 7 through the cooperation of the worm 14 and the worm gear 7. With the rotation of the worm gear 7, the inner wall of the arc-shaped groove 8 extrudes the suction pipe 13, causing the suction pipe 13 to be stressed and move directionally under the guidance of the guide frame 6, thereby adjusting the area formed by the four suction nozzles, so that it can better adsorb different size chips. Subsequently, the air is sucked out from the base pipe 1 to form a negative pressure, and the air guide cylinder 11 is communicated with the suction pipe 13 through the fixed pipe 9 and the mounting pipe 10. The fixed pipe 9 can slide relative to the mounting pipe 10 to follow the movement of the suction pipe 13. At the same time, the piston sleeve 16 can block the gas while ensuring the sliding of the fixed pipe 9, avoiding the leakage of gas from the gap between the fixed pipe 9 and the mounting pipe 10, and ensuring that the suction nozzle at the bottom end of the suction pipe 13 can adsorb the chip. The mounting frame 4 of the device is fixedly connected with the external mobile device, and the function of moving the chip is realized by moving the mounting frame 4.

In addition, the supporting plate 18 supports the fixed ring 19 through the ball bearings, which can reduce the influence of gravity on the sealing bearing 17, and also will not increase the friction between the two. When the adsorbed chip needs to be rotated, the first servo motor 2 can be started to drive the air guide cylinder 11 to rotate through the driving bevel gear 3 and the driven bevel gear 5. The air guide cylinder 11 can drive the mounting box 12 to rotate, thereby adjusting the angle of the chip.
