technical field [0001] The invention relates to battery gluing equipment, in particular to a complete set of gluing equipment and a gluing process for assembled batteries of new energy vehicles. Background technique [0002] The power of new energy vehicles is provided by batteries, and new energy vehicle batteries are assembled from multiple independent lithium battery cells and end plates.

Problems solved by technology

At present, the gluing process of lithium batteries is generally carried out manually. First, the battery is placed under the cleaning mechanism for high-pressure air blowing to clean the dust on the surface of the battery, and then manually transferred to the bottom of the gluing machine for manual operation. The gluing machine applies glue to the surface of the battery. This method of gluing is not only slow, but also because the thickness of the gluing layer is thin, it is difficult for workers to control the thickness of the gluing layer when gluing, resulting in the failure of the battery cell. Uneven glue coating on the end face affects the assembly of the battery cell

Since the cleaning mechanism and the gluing machine are two independent machines, the battery cells must be manually moved for each operation, and the weight of a single car lithium battery is heavy. The workers repeatedly carry it for a long time, which is not only labor-intensive, but also As the working time increases, the labor efficiency will decrease accordingly; at the same time, because the manual handling will often touch the surface of the battery cell, this will cause secondary pollution to the battery after cleaning, which will affect the bonding of the subsequent glue

After the surface of the existing battery core is glued, it is also manually transported and stacked, and the handling efficiency is low; moreover, the glue layer that has just been glued has a high temperature and a certain viscosity, and it may be difficult to carry it manually. Be careful to touch the glue, which will easily damage the thickness and uniformity of the glue layer of the cell, increase the difficulty of manual handling, reduce the handling efficiency, and there are certain safety hazards

Therefore, the existing technology has the problems of slow glue application speed, uneven glue layer on the surface of the battery cell, high labor intensity, low work efficiency, easy secondary pollution to the battery, and potential safety hazards.
