Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically to a fixing device for automatically applying adhesive to lithium battery cells. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental conditions. Therefore, lithium-ion batteries were not widely used for a long time. With the development of science and technology, lithium-ion batteries have now become mainstream. Currently, most lithium-ion batteries are manufactured by manual application of adhesive, which is time-consuming and prone to leaving fingerprints on the tape. Therefore, automatic adhesive application machines have been developed. However, the fixing devices of existing automatic adhesive application machines are slow, and some devices are difficult to pre-position before workers place the battery cells on them for fixing.

[0003] For example, the automatic adhesive-applying fixing device for lithium battery cells disclosed in authorization announcement number CN 208298956 U, although it adds a pushing cylinder and a pressing cylinder to fix the position of the battery cell, and the baffle and push plate work together to ensure that the sides of the battery cell are aligned before the automatic adhesive application, completely solves the problem of battery cell displacement and misalignment during the adhesive application process and improves the product yield. However, it does not solve the problem that existing workers cannot pre-position the cells when placing them. Therefore, we propose an automatic adhesive-applying fixing device for lithium battery cells. Utility Model Content
