A pole piece dust brushing mechanism

Abstract

The invention relates to a pole piece dust brushing mechanism, which includes a motor, a first gear shaft, a first gear, a second gear shaft, a second gear, a third gear shaft, a third gear, a fourth gear shaft, a fourth gear, Support plate, left brush ash box, right brush ash box, left brush wheel, right brush wheel, left connecting block, right connecting block, sliding block, guide rod, adjusting plate, left sliding plate, right sliding plate, cylinder, cylinder connection The overall structure of the head, slide rail, and pole piece dust brushing mechanism is reasonably designed. When the cylinder drives the left and right skateboards to move to the left and right outer or inner sides along the slide rail, the corresponding sliding block moves down or up along the guide rod to ensure that the left and right brushes The moving distance of the wheel system is equal and is always symmetrical about the center line of the two brush wheel axes, which improves the quality of dust brushing, has a stable structure, and fast dust brushing speed. In addition, the addition of a handle mechanism makes it easy to replace the brush wheels without dismantling the entire mechanism, saving manpower and time. , strong practicality.

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
