Problems solved by technology

[0007] In order to overcome the disadvantages of low production efficiency, uneven temperature distribution, insufficient energy utilization and poor glue quality of the existing thermal compounding method, the invention provides a tab forming mechanism, a forming method and a tab forming equipment. When passing through the conductor, the conductor heats up and the temperature rises based on the principle of current thermal effect. Using a DC power supply, the current flows into the parts of the metal strips on both sides of the tabs that are not provided with tabs, so that the metal strips between the first electrode and the second electrode quickly Reach the temperature required for thermal compounding, effectively improve production efficiency, improve product quality, and reduce energy loss

Abstract

The invention discloses a tab molding mechanism, molding method and tab molding equipment. The tab molding mechanism comprises a DC power supply, a laminating mechanism formed on a metal belt, and a conducting mechanism formed below the metal belt; the conducting mechanism comprises a first electrode and a second electrode arranged at the locations without tab sealant on the corresponding metal belt at two sides of the tab sealant; the positive electrode of the DC power supply is connected with the first electrode, and the negative electrode of the DC power supply is connected with the secondelectrode; in the thermal compounding, the laminating mechanism and the conducting mechanism are adhered at the metal belt locations at two sides of the tab sealant; a loop is formed among the positive electrode of the DC power supply, the first electrode, the metal belt, the second electrode and the negative electrode of the DC power supply; the DC power supply outputs the current, and the metalbelt between the first electrode and the second electrode are heated under the current thermal effect so that the tab sealant is hot-molten on the metal belt; the production efficiency is effectivelyimproved, the product quality is improved, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of tab manufacturing for power batteries, and more particularly relates to a tab forming mechanism, a forming method, and tab forming equipment. Background technique [0002] Lithium-ion polymer power batteries are widely used in electric vehicles, backup power supplies, etc., and are an important branch of new energy vehicle batteries. The power tab (hereinafter referred to as the tab) is a key part of the battery, which is made of a chemically treated metal sheet (aluminum or copper nickel-plated) and a pair of tab glue formed on the upper and lower surfaces of the metal sheet. Such as figure 1 , figure 2 shown. The quality of the tab directly affects the performance of the battery, especially the safety and service life. [0003] Tab forming refers to the chemically treated metal strip and tab film as materials, the metal strip and tab glue are fused by heating (hereinafter referred to as thermal com...
