Problems solved by technology

Due to the current traditional material tools: during the preparation process, there is easy static electricity, and the injection molding process tends to stick to dust, unknown dirt, and particles after the PVC material is melted at high temperature, resulting in poor convex and concave points on the surface
In addition, there are 5 to 9 processes at the back end of the battery manufacturer. During the turnover process, various degrees of damage, scratches, convex and concave points, and poor indentation will be infected on the battery surface. Finally, the battery has the risk of short circuit and the possibility of burning may cause safety hazards.

Embodiment 1

[0018] A kind of lithium-ion battery protective protection PVC bubble film box manufacturing process, its concrete steps are as follows:

[0019] 1. Step 1: Design the corresponding model and make the mold according to the process requirements;

[0020] 2. Step 2: First, preheat the injection molding equipment for 15 minutes, add raw materials according to the ratio, stir evenly, bake for 1.5 hours, then add the rubber material in the state of solid particles into the hopper, and send the rubber particles to melt into The liquid state is cut and compressed by the screw thread, so that the density and viscosity are squeezed evenly; secondly, the injection filling process: this process is that the liquid passes through the technical chamber, and the pre-molded liquid rubber is passed through the screw in the barrel. The driving force is to inject the plastic into the mold cavity. This process is divided into two stages: the first stage, the liquid rubber enters the mold cavity f...

Abstract

The invention discloses a manufacturing process of a lithium ion battery protection PVC bubble film box. The manufacturing process comprises the following steps that 1, a corresponding model is designed according to process requirements, and a mold is manufactured; 2, preheating is conducted on injection molding equipment for 15 minutes-20 minutes, raw materials are added according to the proportion, uniform stirring is conducted, baking is conducted for 1.5 hours-2 hours, solid particle colloidal materials are added into a hopper, the colloidal particles are fed to be molten into a liquid state in a screw return mode, so that the density and the viscosity are uniform, injection mold filling is conducted, plastic is injected into a mold cavity by the liquid colloidal materials through thepushing force of a screw, and pressure maintenance is conducted; 3, the body temperature of an injector is controlled to be 450 DEG C-500 DEG C, and the cold hydrolysis time is 10 seconds-12 seconds;and 4, a primary PVC artificial leather semi-finished product is formed, and secondary air bubble film injection molding injection mold filling is conducted. The protection PVC bubble film box manufactured through the manufacturing process is perfect in structure and infinite in shape change, damage, scratches, convex-concave points and poor indentations of different degrees on the surface of a battery can be reduced, battery defects are reduced, and the cost and the rejection rate of manufacturers are reduced.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a manufacturing process of a protective PVC bubble film box for lithium-ion batteries. Background technique [0002] The advantages of lithium-ion batteries are: light weight, long life, high energy density, no memory effect, high safety performance, and customizable shape and size. Lithium-ion battery turnover and related disadvantages in the production process: battery turnover and packaging and shipments during the production process are likely to cause the surface aluminum-plastic film to be easily damaged, scratched, convex and concave, and indented. Security risks. [0003] With the continuous improvement of people's living standards and pace of life, the business philosophy of people-oriented, customer first, and pursuit of excellence.
