Automatic reel changing device for pole pieces

Abstract

The invention relates to an automatic reel changing device for pole pieces. The automatic reel changing device for the pole pieces comprises a substrate, wherein a main material reel mechanism and a standby material reel mechanism which back up for each other are respectively mounted on two sides of the substrate; a plurality of rollers which are arrayed in two rows and facilitate free suspending of the pole pieces are respectively mounted in the middle of the substrate; a left upper side adsorption positioning mechanism and a right upper side adsorption positioning mechanism which adsorb side surfaces of upper parts of the guided-out pole pieces are mounted on the upper part of the substrate; a left lower side adsorption positioning mechanism and a right lower side adsorption positioning mechanism which adsorb side surfaces of lower parts of the guided-out pole pieces are mounted on the lower part of the substrate; a pole piece shearing mechanism which cuts off the pole pieces from the middles simultaneously is mounted on the substrate and positioned between the right upper side adsorption positioning mechanism and the right lower side adsorption positioning mechanism; a left side pole piece changeover mechanism and a right side pole piece changeover mechanism which are used for adhering two sides of a head part of each new pole piece to two sides of the tail part of a corresponding running pole piece are respectively mounted on two corresponding sides of the substrate; and a main waste material reeling mechanism and a standby waste material reeling mechanism which are used for reeling and withdrawing the waste materials of the head parts of the new pole pieces are mounted on sides of the top of the substrate.

Description

【Technical field】 [0001] The invention relates to battery production equipment, in particular to winding equipment for circular electric cores, winding equipment for square electric cores, automatic pole piece rewinding devices for scraper machines or sheet making machines. 【Background technique】 [0002] Existing battery manufacturing generally adopts fully automatic winding equipment, but in the production process, fully automatic winding, lamination, bag making and other processes, including the process of unwinding the pole piece coil, currently generally adopts single-station unwinding , when the reel is used up, the whole equipment should be shut down, and the reel should be changed manually. Knots connect the end of the original tape to the initial length of the new tape. This method of changing rolls and connecting tapes causes a delay in shutdown and reduces production efficiency. Human assistance is required, which reduces the efficiency of the machine and increas...

AI Technical Summary

Problems solved by technology

This method of changing rolls and connecting tapes causes a delay in shutdown and reduces production efficiency. Human assistance is required, which reduces the efficiency of the machine and increases the chance of contact between people and the pole piece, causing pollution to the pole piece material; at the same time, it increases the equipment idle time. Time will seriously affect the efficiency of equipment, resulting in waste of materials, inconvenient automation operations, large labor consumption, and poor controllability of product quality
