Ultra-thin waterproof shell and battery integrally molded structure, manufacture apparatus and manufacture method

Abstract

The invention relates to an ultra-thin waterproof shell and battery integrally molded structure, a manufacture apparatus and a manufacture method. The ultra-thin waterproof shell and battery integrally molded structure includes a plastic shell and a flexible battery which is integrally injected and molded at the inner side of the plastic shell; one side of the flexible battery, which is opposite to the of the plastic shell, is covered with waterproof silica gel; a feed through hole is formed in the waterproof silica gel; at least one positioning through hole which pass through the two sides of the flexible battery is formed in the flexible battery; and one part of the plastic shell extends to the one side of the flexible battery through the positioning through holes so as to be molded as the fixing structure of the flexible battery. In the manufacture apparatus, a second mold portion is provided with movable positioning pins; and the movable positioning pins are configured to be controllably inserted into the positioning through holes in the flexible battery and to controllably retreat from the positioning through holes in the flexible battery. The ultra-thin integrally molded structure has good water waterproof performance and flexibility. Various surface treatment can be performed on the ultra-thin integrally molded structure.

Description

[0001] This application is a divisional application of an invention patent application with application number 201410545703.2 and titled "Ultra-thin waterproof shell battery integral molding structure, production equipment and production method" technical field [0002] The invention relates to an ultra-thin waterproof case battery integrally formed structure, manufacturing equipment and a manufacturing method. Background technique [0003] 3C electronic products (computer (Computer), communication (Communication) and consumer electronics (Consumer Electronic)) thinner, flexible, waterproof is the future development trend and necessary for wearable devices. For example, today's mid-to-high-end mobile phones have two characteristics of ultra-thin and waterproof, and are also limited by the thick characteristics of traditional batteries (generally 5mm, ultra-thin batteries are above 3.5mm), and more than 50% of the overall structure The thickness of the mobile phone is occupie...

AI Technical Summary

Problems solved by technology

[0005] In 3C electronic products and wearable flexible products, plastic raw materials in injection molding need to be melted at high temperature before they can be flow-filled and molded (the melting temperature of plastic raw materials for structural parts is generally around 300°C), and the high temperature that existing batteries can withstand The temperature is around 100°C, and the maximum temperature is not more than 200°C. The battery cannot withstand the high temperature process limit of plastic molding. The existing 3C electronic products are combined with plastic structural parts by assembly methods, and there is no related integrated molding process.

[0006] At present, flexible wearable devices are mainly molded through soft rubber. Although soft rubber materials can meet the flexibility requirements, due to the limitations of the material itself, it is difficult to perform complex surface treatment processes on the surface, which cannot meet the appearance of 3C electronic products and future flexible wearable devices. The demand for fashion and novelty urgently requires a structure and its preparation process that can not only meet the flexible demand, but also perform complex surface treatment.
