[0002] Lithium power mainly includes two types of laminated battery cells and wound batteries. The laminated lithium battery unit for medium power is a major processing design, but before the final laminated lithium battery unit, half of the The chip unit lithium battery needs to be accurately bonded with a layer of insulating film (PE or PF), and the chip unit battery needs hot-melt bonding instead of adhesive. The existing process uses two One-way process, that is, hot melt and then cut in the mold, which is labor-intensive and time-consuming, and the cost is high

Embodiment Construction
[0015] As shown in the figure, lower template 1, lower template heater 2, lower forming mold 3, groove 3-1, template guide post 4, upper template 5, upper template heater 6, cutter 7, film 8, lithium battery chip Unit 9.
[0016] Such as figure 1 As shown, the mold base includes an upper template, a lower template and template guide pillars 4 mold clamping guides, an upper template heater 6 (the upper template is a planar structure) is installed on the upper template, and the lower molding die 3 is installed on the lower template 1, and the upper template The upper template heater 6 is installed on the template 5 and descends or rises along the template guide post 4. A rectangular cutter 7 is installed on the surface of the upper template. The area cut by the cutter is slightly larger than the surface area of the lower forming die 3. At the same time, the upper The template heater is a built-in structure, and the electric heating PTC product or the heater with heat transfer...

Description
technical field [0001] The invention relates to a mold for processing a lithium battery chip unit, in particular to a method and a mold for laminating an insulating film of an accurate size through simultaneous heating. Background technique [0002] Lithium power mainly includes two types of laminated battery cells and wound batteries. The laminated lithium battery unit for medium power is a major processing design, but before the final laminated lithium battery unit, half of the The chip unit lithium battery needs to be accurately bonded with a layer of insulating film (PE or PF), and it needs hot-melt bonding with the chip unit battery and it is not suitable to use an adhesive. The existing process uses two The first process, that is, cutting in the mold after hot melting, is more labor-intensive and time-consuming, and the cost is higher. [0003] The process of cutting and melting integration in the heating and melting mold is a technological improvement. Contents of ...
