A stacked coating device

By setting material boxes and coating components on both sides of the coating worktable through the stacking and coating device, the coating can be applied while stacking cells, which solves the problem that the adhesive cannot wet the middle part of the stacked body, and improves the performance and production efficiency of the stacked battery.

AI Technical Summary

Technical Problem

In the current production process of stacked batteries, the high viscosity of the adhesive and the thick thickness of the laminate prevent the adhesive from penetrating to the middle of the laminate, resulting in poor performance of the stacked batteries.

Method used

A stacked adhesive coating device is used. By setting a first material box and a second material box on opposite sides of the adhesive coating worktable, the adhesive coating is carried out while stacking the sheets by using the adsorption top cover and the adhesive coating component to move along the Z and X axes, ensuring uniform adhesive bonding at both ends and the middle position of the stacked body.

Benefits of technology

It improves the performance of stacked batteries, has a high degree of structural integration, saves space, and improves production efficiency.

Abstract

This utility model discloses a lamination coating device, belonging to the field of lamination battery production technology. The lamination coating device includes a coating worktable, a first material box component, a coating component, and a second material box component. The first material box component is located on one side of the coating worktable and includes a first receiving box and a first adsorption top cover. The first adsorption top cover is used to adsorb the negative electrode sheet in the first receiving box and confine its position on the coating worktable. The coating component is located above the coating worktable and can move along the Z-axis to be close to the coating worktable and along the X-axis to apply adhesive to the negative electrode sheet on the coating worktable. The second material box component is located on the other side of the coating worktable and includes a second receiving box and a second adsorption top cover. The second adsorption top cover is used to adsorb the positive electrode sheet in the second receiving box and stack it on the coated negative electrode sheet, and to move the coating component along the X-axis to apply adhesive to the positive electrode sheet. This lamination coating device can apply adhesive while laminating, thereby improving the performance of the lamination battery.
