Ultra thin waterproof shell battery integrated molding structure, production equipment and production method

Abstract

The invention discloses an ultra thin waterproof shell battery integrated molding structure, production equipment and a production method. The ultra thin waterproof shell battery integrated molding structure comprises a plastic shell and a flexible battery which is integrally injected and formed at the inner side of the plastic shell. The other side of the flexible battery opposite to the plastic shell is covered by waterproof silica gel which is provided with a feeding through hole. The production equipment comprises a first mould part and a second mould part which are used for molding and shaping and at least a third mould part for silica gel shaping. The second mould part is used for placing the flexible battery. The first mould part and the second mould part are combined to form an injection molding cavity. The second mould part is internally provided with a local cooling system corresponding to the placing area of the flexible battery, and the local cooling system is used for preventing the overhigh temperature of the flexible battery in the process of injection molding. According to the ultra thin waterproof shell battery integrated molding structure, the ultra thin integrated molding structure with good waterproof performance can be realized, the ultra thin integrated molding shell is flexible, and various surface process can be carried out at the same time.

Description

technical field [0001] The invention relates to an ultra-thin waterproof case battery integrally formed structure, manufacturing equipment and a manufacturing method. Background technique [0002] 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 occupied by the battery, and there is no room for optimization of the remaining mobile phone structure, which seriously restricts the development needs of thin and light mobile phones. At present, the thickness of the world's thinnest mobile phone is 5.75...

AI Technical Summary

Problems solved by technology

[0004] 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.

[0005] 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.
