Abstract

The invention relates to a polymer polar ear welding method, which comprises that: a, cutting the length of polar ear; b, putting cathode polar ear at the middle of copper foil, aligning the sealing film and upper edge of baffle film; c, moving to ultrasonic welding machine, pressing down battery, making upper face of battery horizontal with welding base, and welding; d, putting anode polar ear at middle of copper foil relative to electric corn, aligning the sealing film and the upper edge of baffle film; e, moving to ultrasonic welding machine, pressing down the battery, making upper face of battery horizontal with welding base, welding; f, cutting off abundant copper and aluminum foils; g, bending welding area toward to side of battery for 90degree, keeping two polar ears parallel. The invention can reduce processes and improve welding speed.

Description

Technical field: [0001] The invention relates to a production method of laminated polymer batteries, in particular to a polymer tab welding method. Background technique: [0002] The existing welding process is as follows: firstly weld the fluid metal foils 1 of each level of the same capital punishment together (as shown in Figure 2), then cut off the excess metal foil (as shown in Figure 3, and then connect the metal foil with the corresponding, The tab 2 with sealing film 3 is welded (as shown in Figure 4), and finally the welding point is bent to 90 degrees. This welding process needs to be welded twice, and there are many steps, and then the welding positioning is difficult, and it is easy to cause two tabs High and low, welding speed is slow. Invention content: [0003] The technical problem to be solved by the present invention is to provide a polymer lug welding method, which can reduce the operation steps, increase the welding speed, and make the lug position con...
