A pole piece dust brushing mechanism

Abstract

The invention relates to a pole piece ash brushing mechanism good in symmetry. A motor, a first gear shaft, a first gear, a second gear shaft, a second gear, a third gear shaft, a third gear, a fourthgear shaft, a fourth gear, a supporting plate, a left ash brushing box, a right ash brushing box, a left brush wheel, a right brush wheel, a left connecting block, a right connecting block, sliding blocks, guiding rods, an adjusting plate, a left sliding plate, a right sliding plate, an air cylinder, an air cylinder connecting head and sliding rails. The pole piece ash brushing mechanism is reasonable in integral structure design, when the air cylinder drives the left sliding plate and the right sliding plate to move towards the left-right outer sides or inner sides along the sliding rails, the corresponding sliding blocks move downwards or upwards along the guiding rods, it is guaranteed that the moving distances of a left brush wheel system and a right brush wheel system are equal and are constantly symmetric relative to the axis center lines of the two brush wheels, the ash brushing quality is improved, the structure is firm, and the ash brushing speed is high; and in addition, a pull handle mechanism is additionally arranged so that brush wheel replacement can be convenient, detachment of the whole mechanism is not needed, manpower and time are saved, and practicability is high.

Description

technical field [0001] The invention relates to the field of lithium ion battery manufacturing, in particular to a pole piece dust brushing mechanism. Background technique [0002] At present, lithium-ion film making machines and winding machines are equipped with pole piece dust brushing mechanism, which brushes the pole piece to ensure the cleanliness of the pole piece and reduce poor processing. Existing pole piece dust brushing mechanism such as figure 1 As shown, the motor drives the two brushes to rotate in reverse through the gear set, and the pole piece passes through the middle of the two brushes to brush dust. This mechanism has the following defects: First, the brush wheel is opened, closed and rotated by the head of the cylinder. Drive, the brush wheel does not move symmetrically around the center line, and the left and right shaking causes uneven dust removal and unsatisfactory dust removal effect; second, the service life of the brush wheel is limited, and it ...

Existing pole piece dust brushing mechanism such as figure 1 As shown, the motor drives the two brushes to rotate in reverse through the gear set, and the pole piece passes through the middle of the two brushes to brush dust. This mechanism has the following defects: First, the brush wheel is opened, closed and rotated by the head of the cylinder. Drive, the brush wheel does not move symmetrically around the center line, and the left and right shaking causes uneven dust removal, and the dust removal effect is not ideal; second, the service life of the brush wheel is limited, and it needs to be replaced after a certain period of time. The existing dust brushing mechanism replaces the brush. When brushing the wheel, it is necessary to remove the whole mechanism from the whole machine and then disassemble the brushing mechanism. It is difficult and inconvenient to replace, and it takes a lot of labor and time; third, the gap between the brush box or the shield is small , not conducive to film
