A famous mobile phone manufacturing company has greatly delayed the production of mobile phones because of the poor quality of mobile stamping parts. Mobile phone manufacturing companies hope to quickly and accurately obtain 3D data of precision stamping parts of mobile phones, and provide data support for secondary design of mobile precision stamping parts and quality inspection.

Practical problems

1. The precision stamping parts of the mobile phone need to be used with the circuit board, and the accuracy of the hole position and the position of the card slot on the stamping part is particularly high.

2. The data of the precision stamping parts of the mobile phone obtained by the traditional measuring method is insufficient, and the secondary design and the quality inspection of the product cannot be performed.

solutions

For some features of mobile precision stamping parts, Huaguang 3D engineers proposed solutions: 3D scanner 3DM (fast acquisition of high-precision 3D data of mobile phone aluminum) + reverse design software Geomagic Studio (pointing mobile phone precision stamping point cloud data) Converted to triangular mesh surface data), the secondary design of mobile phone precision stamping parts.

1. Preparation in the early stage: dusting, sticking

Because there are many faces on the precision stamping parts of the mobile phone, it is not suitable for the marking points on the sample. Huaguang 3D engineers use multi-angle 3D scanning turret. Fix the precision stamping parts of the mobile phone on the turntable, and then put the mark points around the turntable, so that the data can be automatically stitched without attaching the mark points on the precision stamping parts of the mobile phone.

2, 3D scanning

The precision stamping parts of the mobile phone are fixed on the three-dimensional scanning turntable, and the turntable is rotated, so that the 3D scanner 3DM can obtain the three-dimensional data of the precision stamping parts of the mobile phone in an all-round manner, and the complete three-dimensional data can be obtained in only 10 minutes with an accuracy of 0.02 mm. The acquired mobile phone precision stamping parts have large point cloud data density and good detail reduction characteristics. The three-dimensional data is imported into the reverse design software to carry out the secondary design of the mobile phone precision stamping parts.
