Thickness measuring and gluing platform for isolating membranes on two sides of wound battery cell

Abstract

The invention discloses a thickness measuring and gluing platform for isolating membranes on two sides of a wound battery cell, and relates to the field of battery cell gluing equipment. The thicknessmeasuring and gluing platform aims to solve the problem that the thickness difference and the length difference between the existing same type of battery cells bring adverse effects on gluing. The thickness measuring and gluing platform is technically characterized by comprising a supporting seat for bearing the battery cell, a left side camera detection assembly, a right side camera detection assembly, a left side pressing assembly and a right side pressing assembly, wherein the left side camera detection assembly and the right side camera detection assembly are borne on the two sides of thesupporting seat respectively and used for feeding back the length size of the battery cell, the left side pressing assembly and the right side pressing assembly are borne on the two sides of the supporting seat respectively, and the left pressing assembly and the right pressing assembly are provided with a left thickness measuring assembly and a right thickness measuring assembly which are used for feeding back the thickness size of the battery cell. The thickness measuring and gluing platform can overcome the negative influence of the thickness difference and the length difference between the same type of battery cells on gluing, so that the gluing effect is improved.

Description

Technical field [0001] The invention relates to the field of electric core gluing equipment, and more specifically, it relates to a thickness measurement gluing platform for diaphragms on both sides of a wound electric core. Background technique [0002] At present, when the soft wrap wound battery core is coated with glue, because there is also a thickness difference between the same type of batteries, it will cause the glue to be unable to coat the outermost isolation film or to coat the aluminum foil over the outermost isolation film; At the same time, there is also a difference in length between the same type of batteries, which will cause the gap between the glue needle and the isolation film to be inaccurate, which will affect the adhesion effect of the glue. Too close will cause the glue to accumulate or the isolation film will interrupt the track. If the distance is far away, the glue will not stick to the isolation film and fall and the track will be interrupted. Summar...

Problems solved by technology

[0002] At present, when the soft-wrapped winding cells are glued, because there is a difference in thickness between the cells of the same type, the glue cannot be coated with the outermost isolation film or coated with aluminum foil beyond the outermost isolation film; At the same time, there is also a length difference between the cells of the same type, which will lead to inaccurate spacing between the glue needle and the isolation film, which will affect the glue adhesion effect. If the distance is too close, the glue will accumulate or the track will be interrupted by the isolation film. If it is far away, the glue will not stick to the isolation film and the track will be interrupted.
