The one end that collection silo 25 was kept away from to two guide slots 26 is all located to receive the top of silo 27 to collect the utmost point ear waste material of two stations simultaneously, be convenient for the technology personnel concentrated handling utmost point ear waste material, avoid utmost point ear waste material to scatter and lead to difficult clearance.

In one embodiment, as shown in FIG. 1. The feeding assembly 30 includes a carrier plate 31 fixed to the base plate 10, a horizontal pushing cylinder 32 provided on the carrier plate 31, and a pushing plate 33 fixed to a movable end of the horizontal pushing cylinder 32. The horizontal pushing cylinder 32 is used to drive the battery close to the cutting assembly 20 by means of a push plate 33. That is, the battery may be placed at an initial position of the carrier plate 31 and then driven to a preset position of the carrier plate 31 by the horizontal pushing cylinder 32.

Further, the carrier 31 is provided with a pair of parallel baffles 34 spaced apart. The pair of baffles 34 enclose to form a limit groove 35, and the battery and the pushing plate 33 are all arranged in the limit groove 35, so that the movement of the battery on the carrier plate 31 can be limited through the limit groove 35.

Further, the carrier 31 is further provided with mounting holes 311. The mounting hole 311 is provided with a suction cup 36, and a vacuum generator (not shown) communicating with the suction cup 36 is further provided on a side of the carrier plate 31 facing away from the suction cup 36. The vacuum generator is used for making the sucking disc 36 generate negative pressure so as to suck the battery at the preset position on the carrier plate 31. Therefore, the detachable fixed battery can be realized through the adsorption action of the vacuum generator and the sucker 36, so that the battery is prevented from moving when the tab is cut, and the accuracy of tab cutting is affected.
