Lithium battery cathode material sintered bowl full-automatic cleaning workstation

Abstract

The invention relates to a lithium battery cathode material sintered bowl full-automatic cleaning workstation. The workstation comprises a bowl discharge unit, a bowl body conveying units, a bowl bodycleaning unit, an electrode conveying unit, an electrode deburring unit and a sintered bowl corrosion and crack detection unit. The bowl discharge unit is used for clamping, fixing and moving bowl bodies, transferring vibration to the bowl bodies and taking out electrodes from the bowl bodies. The bowl body conveying unit is used for transmitting and locating empty bowl bodies. The bowl body cleaning unit is used for cleaning the bowl bodies hermetically. The electrode conveying unit is used for cleaning the surfaces of the electrodes and conveying the electrodes to the electrode deburring unit. The electrode deburring unit is used for detecting whether burrs exist on the surfaces of the electrodes, removing through burrs and blowing the surfaces of the electrodes. The sintered bowl corrosion and crack detection unit is used for detecting whether the bottoms of the bowl bodies are corroded or cracks exist on the side faces of the bowl bodies or not.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a workstation for cleaning and detecting the surfaces of bowls and electrodes used in the production process of lithium batteries and removing supplementary materials. Background technique [0002] In the process of preparing lithium batteries, it is necessary to put polar materials into a special pot and push them into a sintering furnace for sintering to prepare the positive and negative electrodes of the lithium battery. After the sintering process is completed and the pot is unloaded, there will be residues in the pot body, and the existence of these residues will have a great impact on the subsequent sintering process in the pot body, so these residues usually need to be cleaned; at the same time, the electrode surface is also Some dust will remain, and because the inner surface of the bowl is not smooth or the sintering process is not perfect, there are often some...

AI Technical Summary

Problems solved by technology

[0003] Some solutions have been proposed for the cleaning of bowls and electrodes in the prior art. For example, in the literature entitled "Lithium Battery Electrode Brushing and Dust Removal Machine and Lithium Battery Electrode Brushing and Dust Removal Process", it is proposed to clean the electrode surface with a brush. Clean, and use the vacuum cover to suck the dust on the electrode, but this method of cleaning the surface with a brush may cause damage to the electrode surface, and the cleanliness of the brush needs to be maintained. In addition, the vacuum cover is only roughly located at the electrode transmission Above the path, a sealed environment cannot be formed, resulting in poor dust extraction effect and unfriendly environment, and only one surface of the electrode can be cleaned at a time

In the existing technology entitled "Full-automatic powder brushing machine", the brush is also used to clean the pole pieces, and only one surface can be cleaned at a time, which leads to the need to introduce an electrode reversal mechanism, the system structure is complex and efficient. low
