Description

Technical Field

[0001] This invention relates to the field of electronic device component manufacturing technology, and more particularly to a high-precision planar bracket with multiple steel sheets for electronic devices. Background Technology

[0002] As electronic devices such as smartphones, tablets, and wearables become thinner, lighter, and more powerful, their internal components are becoming increasingly densely packed. This places higher demands on planar brackets used to fix and support these components, especially in large-size bracket products. These brackets must not only meet the high-precision standard of controlling flatness error within 0.4mm, but also adapt to complex structures integrating multiple components. Traditional bracket manufacturing processes are gradually revealing many technical bottlenecks.

[0003] When the bracket needs to be composed of multiple independent steel sheets, the traditional process requires the development of a stamping die for each steel sheet, which requires the investment of multiple sets of equipment costs for die development alone. In addition, the independent steel sheets need to be stamped in steps, and the subsequent injection molding process requires the steel sheets to be inserted into the mold one by one, which not only consumes a lot of manpower, but also prolongs the production cycle, resulting in high overall manufacturing costs.

[0004] Secondly, the positioning accuracy of independent steel sheets within the injection mold is difficult to standardize, and there is a lack of effective structural support. During the injection process, the flow pressure of the molten plastic can easily cause the steel sheets to shift. At the same time, there is no additional constraint structure when the plastic cools and shrinks, which can easily cause overall deformation of the support and further aggravate the flatness deviation problem.

[0005] Therefore, it is necessary to develop a high-precision planar bracket with multiple steel plates for electronic devices to solve the above problems. Utility Model Content
