Description

Technical Field

[0001] The utility model relates to the field of electrode patch equipment, in particular to an electrode strip bonding mechanism. Background Art

[0002] The electrode strip is a strip formed by cutting the electrode sheet, which is still a electrode sheet in essence. When the batteries are used in groups, the electrode sheets need to be bonded to the negative electrodes of the multiple batteries in the group to obtain connectivity. Due to the different number of batteries used in the group, the structures of the electrode sheets that need to be combined are different to ensure that the electrode sheets combined into one can meet the installation size requirements of the battery group. The currently commonly used combined electrode sheets are composed of 4 different types of electrode sheets bonded in sequence.

[0003] After searching, it was found that the publication number is CN210805917U, and the name is an automatic electrode sheet bonding device. The application proposes that the existing electrode sheet assembly method is to place different electrode sheets in a mold for positioning, and then manually glue and press the electrode sheets into shape. The manual assembly method has bonding errors and causes high labor intensity. The four-axis manipulator drives the suction cup assembly to grab multiple electrode sheets at the same time and place them on the positioning and bonding mobile base for positioning, and with the cooperation of the labeling mechanism, the double-sided tape is pasted on the electrode sheet at the bottom layer. After the positioning and bonding mobile base is reset, the electrode sheet at the upper layer is pressed on the double-sided tape according to the predetermined position again, so as to obtain an integrated electrode sheet finished product; the whole process only requires one person to place and take the material, and the rest of the links are automatically operated by the mechanism, which can not only ensure that the bonding error meets the requirements, but also reduce the labor intensity. However, the application uses a manipulator and a suction cup assembly with complex electronic control equipment, and has a high-precision lifting mechanism. The overall structure is very complex, the cost is high, and the debugging stage is relatively troublesome, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
