When carrying lithium battery pole piece 6, adopt the transport mode of magnetic suspension to replace traditional belt transport, can guarantee to a great extent that to the higher conveying efficiency of pole piece 6, and transportation process are comparatively steady. However, due to the particularity of the magnetic suspension guide rail, the air supply and power supply device moving along with the pole piece 6 cannot be installed, and it is difficult to arrange a fixing device on the conveying jig of the pole piece 6, which can fix the pole piece 6 and cannot damage the surface of the pole piece 6. Referring to fig. 1, the application provides a negative pressure formula pole piece 6 adsorption apparatus, including adsorbing the base, setting up the adsorption part on adsorbing the base and set up on adsorbing the base and with adsorption unit connection's adsorption equipment 1, adsorption part has one at least and adsorbs hole 3, adsorption equipment 1 is used for forming the negative pressure that adsorbs pole piece 6 in adsorbing hole 3. The pole piece 6 is adsorbed by the adsorption device 1 capable of generating negative pressure, so that the pole piece 6 is fixed on the adsorption base, the stability of the pole piece 6 is ensured, and the pole piece 6 cannot incline or misplace in the conveying process. And the negative pressure is adopted to adsorb and fix the pole piece 6, so that the surface contact of a hard object and the pole piece 6 is avoided, and the surface of the pole piece 6 is prevented from being damaged in the fixing process.

Referring to fig. 1 and 2, still be equipped with adsorption tank 4 and adsorption cavity 5 on the adsorption base, adsorption tank 4 is located the upper surface of adsorption base, adsorption cavity 5 is located the adsorption base of 4 bottoms in adsorption tank, adsorption hole 3 sets up on the bottom surface of 6 adsorption tanks 4 of pole piece, adsorption hole 3 is connected with adsorption cavity 5 through adsorbing the passageway in the bottom of adsorption tank 4, adsorption equipment 1 is connected with adsorption cavity 5 at the side of base.

The process that the adsorption equipment 1 and the adsorption base are matched to adsorb the pole piece 6 is as follows: the actuating cylinder starts, and the air lever that drives actuating cylinder is connected with piston rod 12, drives actuating cylinder and starts, pushes piston rod 12 into a certain distance in the piston hole 15. At this time, the compression spring 11 located between the piston rod 12 and the top of the piston hole 15 is compressed by the piston rod 12 pushed in, and the air in the adsorption chamber 5 communicating with the piston rod 12 is pushed out from the adsorption hole 3. Place pole piece 6 at this moment in the adsorption tank that is equipped with adsorption hole 3, the surface and the adsorption hole 3 contact of pole piece 6, will adsorb hole 3 and seal. When the air rod of the air cylinder is separated from the piston rod 12, the spring compressed by the piston rod 12 generates elastic force to eject the piston rod 12 out of the piston hole 15. Because the adsorption hole 3 and the piston hole 15 are connected into a sealed space through the adsorption cavity 5, when the piston rod 12 moves towards or out of the piston hole 15, new air cannot enter the sealed adsorption cavity 5, and negative pressure is formed at the position where the adsorption hole 3 is connected with the pole piece 6, so that the pole piece 6 is adsorbed in the adsorption groove 4.
