Problems solved by technology
It is found in production that when the stirring effect of the trough is not ideal, it will have a negative impact on the coating quality of the pole piece, which is reflected in the large difference in surface density between the trial coating and the normal coating; the fluidity of the upper and lower layers of the slurry in the trough is poor. difference, the areal density fluctuates greatly along the direction of the coating tape, and when it is serious, it needs to be shut down for adjustment, which affects production efficiency and battery yield

The invention discloses a trough stirring device for a transfer type coating machine, belonging to the technical field of lithium ion battery manufacturing. The trough stirring device comprises a stirring rod, a driving mechanism and a horizontal moving mechanism, wherein one end of the stirring rod is in power connection with the driving mechanism; the driving mechanism is connected with the horizontal moving mechanism; and the horizontal moving mechanism is arranged above a trough. A micro motor is installed on a sliding block which reciprocates left and right, and a stirring paddle is connected with a motor shaft through a coupler, so the stirring paddle rotates while moving left and right; and the left-right moving stroke and the left-right moving speed of the stirring paddle are adjustable, and a rotating speed is adjustable, so a good uniform mixing effect on slurry in the left-right direction and the up-down direction is achieved, the stability of the slurry is kept, and pole piece coating quality improvement.
Description
technical field [0001] The invention relates to the technical field of lithium ion battery manufacturing, in particular to a material tank stirring device for a transfer coating machine. Background technique [0002] In the production process of lithium-ion batteries, it is necessary to coat the uniformly dispersed slurry on the current collector and form positive and negative electrodes after drying. This process is mainly done by extrusion coating machine or transfer coating machine. Finished, the quality of the coating directly affects the lithium battery capacity, internal resistance, safety and consistency. The stability and uniformity of the battery slurry have a direct impact on the thickness and surface density of the coating. In order to maintain the stability of the slurry, the prepared slurry needs to be placed in a transfer tank for continuous stirring, and then continuously pumped into the coating machine The trough of the head is used for coating. There is al...
