Automatic battery primary top side sealing machine

Abstract

The invention discloses an automatic battery primary top side sealing machine which comprises a flexible aluminum inputting mechanism, a top sealing mechanism, a two-side sealing mechanism, a transplanting mechanism, a short-circuit testing mechanism, a defective product discharge mechanism and a discharge mechanism, wherein the flexible aluminum addition mechanism conveys an aluminum film to the top sealing mechanism for aluminum film bending and battery top sealing; the transplanting mechanism grasps a battery subjected to top sealing to the two-side sealing mechanism for two-side sealing; after the two-side sealing is completed, the transplanting mechanism grasps the battery which is subjected to the top sealing and the two-side sealing to the short-circuit testing mechanism for a short-circuit test; if the battery is tested to be qualified, the battery is transplanted to the discharge mechanism by the transplanting mechanism to be directly discharged; and if the battery is tested to be unqualified, the battery is transplanted to the defective product discharge mechanism by the transplanting mechanism to be discharged. The battery primary top side sealing machine disclosed by the invention integrates the flexible aluminum input, the battery top-side sealing and the short-circuit detection automation, thereby enhancing the quality control of products, reducing the defective rate of the products, reducing the manual operation, improving the working efficiency and lowering the production cost of the battery.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery aluminum film packaging, in particular to a battery aluminum film automatic sealing packaging machine. Background technique [0002] Due to the advantages of large capacity, long cycle life, and high cost performance, lithium-ion batteries have attracted more and more attention from various industries, such as the electric vehicle industry. Lithium-ion batteries are generally composed of positive electrodes, negative electrodes, separators, electrolytes, and the like. The pole pieces (positive and negative poles) are separated by a diaphragm to make a battery core pack, and then the battery core is packed into a plastic or metal case, and the electrolyte is injected and sealed to form a battery. Wherein, the conduction between the battery core package and the external circuit is connected with the pole through the lug connected with the pole piece. [0003] The sealed packaging of al...

AI Technical Summary

Problems solved by technology

At present, there is no automatic equipment on the market that can automatically complete this process. All of them are packaged manually with aluminum film, and manual sealing and packaging of batteries is prone to phenomena such as uneven folding and inaccurate sealing positions, which will affect the internal structure of the battery and the battery. service life

In addition, manual operation also has potential safety hazards, affects the sealing effect of the battery, is difficult to control the defective rate of the battery, affects the increase in production efficiency and cost, does not adapt to mass production, etc.
