Mobile phone precision stamping parts production plan

2021-07-13 A+ A A-

A well-known mobile phone manufacturing company greatly delayed the production of mobile phones because the production quality of mobile phone precision stamping parts was not satisfactory. Mobile phone manufacturing companies hope to quickly and accurately obtain 3D data of mobile phone precision stamping parts, and provide data support for the secondary design of mobile phone precision stamping parts and quality inspection.

Practical problems

1. The precision stamping parts of mobile phones need to be used with circuit boards, and the accuracy of the hole positions and slot positions on the stamping parts is particularly high.

2. The amount of data obtained by the traditional measurement method of mobile phone precision stamping parts is insufficient, and it is impossible to carry out secondary design and product quality inspection.

Holon solutions

In view of some of the characteristics of mobile phone precision stamping parts, Hualang 3D engineers proposed to use in the solution: 3D scanner HL-3DM (quickly obtain high-precision 3D data of mobile phone aluminum sheets) + reverse design software Geomagic Studio (point mobile phone precision stamping parts The cloud data is converted into triangular mesh data), and the secondary design of mobile phone precision stamping parts is carried out.

1. Preliminary preparations: powder spraying and sticking

Due to the large number of holes on the precision stamping parts of mobile phones, it is not suitable for marking points on the samples. Hualang 3D engineers use a multi-angle 3D scanning turntable. Fix the mobile phone precision stamping parts on the turntable, and then paste the mark points around the turntable, so that automatic data splicing can be realized without sticking the mark points on the mobile phone precision stamping parts.

2. Three-dimensional scanning

Fix the mobile phone precision stamping parts on the 3D scanning turntable and rotate the turntable to enable the 3D scanner HL-3DM to obtain the 3D data of the mobile phone precision stamping parts in all directions. It only takes 10 minutes to obtain the complete 3D data with an accuracy of 0.02mm. The acquired mobile phone precision stamping parts have high point cloud data density and good detail feature reduction. The three-dimensional data is imported into the reverse design software to perform the secondary design of the mobile phone precision stamping parts.
