Feeding system of lithium battery core winder

Abstract

The invention relates to a feeding system of a lithium battery core winder. The feeding system comprises a material storage mechanism and a feeding mechanism. The material storage mechanism comprisesa material storage frame which is detachably arranged on a material storage platform, the material storage frame comprises a material storage base plate, a partition plate and a baffle, wherein the partition plate and the baffle are arranged on the material storage base plate correspondingly and jointly enclose more than one bin, and the positions of the partition plate and / or the baffle on the material storage base plate can be adjusted. The feeding mechanism comprises a feeding moving assembly and a feeding clamp assembly, wherein the feeding moving assembly drives the feeding clamp assemblyto reciprocate on the material storage platform, the feeding clamp assembly comprises a moving base, a lifting cylinder and a lifting connecting block, the moving base is connected with a moving nut,and the moving base reciprocates along with the moving nut. The lifting cylinder is arranged on the moving base, and a piston rod of the lifting cylinder is connected with the lifting connecting block. The lifting connecting block is provided with a vacuum sucker. The feeding system has the characteristics of reliable performance, high production efficiency, high universality and practicability,smooth feeding work and the like.

Description

technical field [0001] The invention relates to a lithium battery winding machine, in particular to a feeding system of the lithium battery winding machine. Background technique [0002] Most of the traditional lithium battery winding machines need manual feeding, that is, the worker sends the positive electrode with one hand and the negative electrode with the other hand, so the proficiency of the workers directly affects the production efficiency and product quality of the lithium battery; and a small part of the lithium battery The core winding machine is changed to automatic feeding, but it still has the following disadvantages: 1. The hopper for stacking electrode sheets cannot be moved or disassembled. When the electrode sheets in the hopper are used up, the feeding process needs to be suspended Refilling greatly reduces the production efficiency; and the refilling is generally carried out under the power-on state, so the traditional refilling work has great safety haz...

[0002] Most of the traditional lithium battery winding machines need manual feeding, that is, the worker sends the positive electrode with one hand and the negative electrode with the other hand, so the proficiency of the workers directly affects the production efficiency and product quality of the lithium battery; and a small part of the lithium battery The core winding machine is changed to automatic feeding, but it still has the following disadvantages: 1. The hopper for stacking electrode sheets cannot be moved or disassembled. When the electrode sheets in the hopper are used up, the feeding process needs to be suspended Refilling greatly reduces the production efficiency; and the refilling is generally carried out under the power-on state, so the traditional refilling work has great safety hazards; the space of the traditional silo cannot be adjusted, so it is only suitable for electrodes of a single size model pieces, poor versatility, and the need to develop silos of different sizes leads to increased costs

2. The holding effect of the traditional feeding mechanism on the electrode sheet is poor, and the fixture is large in size, resulting in a considerable space occupation; the traditional clamping control method is to control the fixture to descend a certain distance step by step (the distance is the distance of the electrode sheet Thickness), to pick up the electrode sheets one by one, but in practical applications, due to a certain error (especially thickness error) in the production process of the electrode sheet, this error may directly affect the clamping effect, resulting in a thinner electrode The sheet may not be effectively picked up, and the clipping reliability is low
