Novel tab rubberizing device

Abstract

The invention relates to a novel tab rubberizing device. The device comprises a base plate, a logistics line used for bearing and transferring batteries is installed on the base plate, a rubberizing mechanism is arranged on the side edge of the logistics line, and a detection mechanism is arranged at the top of the rubberizing mechanism; and the rubberizing mechanism comprises a rubberizing support, two rubberizing mounting plates and a driving part, the rubberizing mounting plates are oppositely arranged up and down, the driving part is used for driving the rubberizing mounting plates to move, the rubberizing support is mounted on one sides of the rubberizing mounting plates, and an adhesive tape is adsorbed on the rubberizing mounting plates in a vacuum manner and is arranged close to the end surfaces of the rubberizing mounting plates. According to the tab rubberizing device, the detection mechanism is arranged at the top of the rubberizing mechanism, the position, needing to be rubberized, of a tab is detected in real time through the detection mechanism, and then the rubberizing mechanism is controlled through the control system, so that the probability of malposition of the rubberizing position is reduced, the yield of battery cells is guaranteed, and popularization and application of the tab rubberizing device in the field of lithium battery tab welding are facilitated.

Description

technical field [0001] The invention relates to the field of lithium battery tab welding, in particular to a novel tab-gluing device. Background technique [0002] In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis: lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries; due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream choice for new energy batteries. [0003] In the production process of soft-packed lithium-ion batteries, the positive and negative electrode foils are pre-welded and cut and then welded together with the tabs. In order to prevent the metal p...

Problems solved by technology

In the prior art, the high-temperature-resistant yellow tape is usually cut into equal lengths, the adhesive surface is facing inward, and the upper and lower sides are symmetrically distributed, and then the yellow tape is adsorbed by vacuum adsorption. The ears are pasted up and down. After the glue is pasted, the glued tabs are inspected at the next station, and the defective products are discharged.

However, due to the R angle of the cell tab foil after welding, the position of the glue is misplaced; and because the glue is usually applied on the basis of the negative plate boundary, the glue standard is single, resulting in a high probability of misplacement of the glue; There is no CCD detection device before, and it cannot be adjusted dynamically in real time, resulting in a high probability of misalignment of the adhesive position and affecting the yield
