[0026] In this embodiment, the first component 3 and the second component 4 respectively abut against the two ends of the sleeve 1, and the negative pressure device reduces the air pressure in the sleeve 1 by abutting against the first component 3 and / or the second component 4 at the two ends of the sleeve 1, thereby generating an air pressure difference inside and outside the sleeve 1, and sucking the balls into the ball receiving holes 10 of the sleeve 1. The rotating driving component 6 allows the sleeve 1 to roll in the ball silo 2, so that the balls are sucked into all the ball receiving holes 10 on the sleeve 1.

[0027] A first linear actuator 30 for driving the first component 3 to move linearly is disposed on the frame S1 , and a second linear actuator 40 for driving the second component 4 to move linearly is disposed on the frame S1 .

[0028] The first linear drive 30 can drive the first component 3 to move in the direction of the first axis X and to rotate around the first axis X; the second linear drive 40 can drive the second component 4 to move in the direction of the first axis X and to rotate around the first axis X.

[0029] The device further comprises an excess ball cleaning assembly 20 located above the ball silo 2 .

[0030] The excess ball cleaning assembly 20 includes a cleaning sheet 200 arranged obliquely, the cleaning sheet 200 is fixed on a moving block 201 that moves obliquely, and an oblique driver 202 is provided on the frame S1 to drive the moving block 201 to move and force the cleaning sheet 200 to be tangent to the outer circumferential surface of the sleeve 1.

[0031] In this embodiment, the excess ball cleaning assembly 20 is a scraper. After the sleeve 1 finishes adsorbing the balls, the scraper is extended, and the scraper plate is completely in contact with the outer wall of the sleeve. At the same time, the first linear drive 30 and the second linear drive 40 synchronously drive the sleeve 1 to rotate relative to the excess ball cleaning assembly 20 to clean the excess or erroneous balls adsorbed on the sleeve 1.

[0032] The first component 3 includes a fixed seat 300 with a sliding through hole, and a telescopic moving cylinder 301 passing through the sliding through hole. The first linear driver 30 is connected to one axial end of the telescopic moving cylinder 301 and enables the telescopic moving cylinder 301 to move linearly. A first sealing tube 302 sealedly connected to one end of the sleeve 1 is provided at one end of the telescopic moving cylinder 301 away from the first linear driver 30.
