Abstract

The invention relates to a coating die head for coating a battery pole piece and a working method of the coating die head. The coating die head comprises an upper die head, a middle die head and a lower die head which are sequentially matched from top to bottom, an upper gasket is clamped between the upper die head and the middle die head, and an upper coating opening for discharging is formed inthe front end of the upper gasket; and a lower gasket is clamped between the middle die head and the lower die head, a lower coating opening for discharging is formed in the front end of the lower gasket, an adjusting long groove extending in the coating width direction is formed in the position, above the upper coating opening, of the bottom surface of the upper die head, a plurality of flow choking blocks are arranged in the adjusting long groove in the length direction of the adjusting long groove, the bottom surfaces of the flow choking blocks are parallel to the upper gasket, and verticaladjusting assemblies used for driving the flow choking blocks to move in the vertical direction are connected to the tops of the flow choking blocks. The coating die head is reasonable in design, coating and discharging of the upper die head can be conveniently adjusted, operation is convenient, adjusting precision is high, and damage to the die head is reduced.

Description

Technical field: [0001] The invention relates to a coating die head for coating battery pole pieces and a working method thereof. Background technique: [0002] Coating is an indispensable process in the production process of lithium-ion batteries, and it is also a key process that directly affects various performances such as battery safety, capacity, and consistency. Slit extrusion machines are usually used to complete coating operations. The slit coating die head of the existing slit extrusion machine mainly includes an upper die head and a lower die head, and an adjusting bolt is installed on the upper die head. Deform to adjust the width of the slit. However, this adjustment method of turning the bolts is not only inconvenient to operate, low in efficiency, and poor in adjustment accuracy, but also requires a high level of experience for the operator, otherwise a slight carelessness will cause irreversible deformation of the slit, and further Leading to the scrapping ...
