The battery cell is divided into a winding battery cell and a lamination battery cell. Referring to fig. 1 and 4, the tab surface of the battery cell is parallel to the upper and lower large surfaces of the battery cell, and generally, the anode tab and the cathode tab are both biased to the plane where the same large surface of the battery cell is located when the tab is formed and ultrasonically welded, and the tab formed battery cell after ultrasonic welding can be divided into an a battery cell 11 and a B battery cell 12 according to the plane where the upper large surface of the battery cell is biased to the plane where the lower large surface is located, and the battery cell formed by only one a battery cell 11 or one B battery cell 12 is called as a single-coil battery cell 10. The tab is a fragile metal foil film, and in order to prevent the tab from being twisted and damaged by pushing and pulling, adhesive tape strips are adhered on both sides of the anode tab and the cathode tab for fixation and protection. First, a piece of base adhesive tape 13 is adhered to the middle part of the tab and the root part of the tab on the deflection side of the anode tab and the cathode tab respectively, and then the base adhesive tape is lapped on the large surface of the deflection side for 20-30mm, which is called as base adhesive, and the battery cell after the base adhesive is adhered is shown in figure 1.
The battery cell with some long tabs is further required to be adhered to the root of the tab from the middle of the tab and then to the top surface of the battery cell by using a Z adhesive tape strip 15 on the offset sides of the anode tab and the cathode tab respectively, and then the battery cell is lapped on the large surface of the offset side of the tab for 20-30mm to strengthen fixation and protection, which is called Z adhesive sticking, and the battery cell after Z adhesive sticking is shown in fig. 3.
Generally, a pair of a battery core 11 and a battery core 12 with the same polarity is adopted to form a double-coil battery core 20 according to the mutual facing Ji Diege of the same polarity, which is called primary pairing, after primary pairing, a side adhesive tape strip 14 is respectively stuck to the middle positions of two side surfaces of the battery core 11 and the battery core 12, and is respectively stuck to the large sides of the electrode lugs of the battery core 11 and the battery core 12 with the offset sides of 30-40mm, so as to keep the appearance of the battery core 11 and the battery core 12 with the aligned electrode lugs, which is called side adhesive sticking, and the double-coil battery core after the side adhesive sticking is paired for the primary time is shown in fig. 2.
Further, two sets of double-coil battery cells 20 are horizontally arranged on the carrier plate, so that homopolar lugs are aligned, the appearance is aligned with the lugs, the distance between the lugs of the two sets of battery cells 20 meets the preset requirement, and the second pairing is called as second pairing, and as shown in fig. 4, the second pairing is used for welding a connecting sheet and a top cover in the next process, and four-coil battery cells are further formed.
The requirements of primer sticking, primary pairing, side glue sticking, Z glue sticking and secondary pairing are as follows: the position and size precision is less than or equal to 1mm. For this purpose, an integrated automated cell adhesive and mating device is required.
