Problems solved by technology

[0003] At present, Shield Frame products are in the process of production. Because the Shield Frame products are relatively large, the mold process is a blanking and bending structure, and then the flatness is adjusted through screws. The main disadvantage is that the stamping die only considers the screw structure to adjust the flatness. However, when this solution is adjusted, multiple screws need to be adjusted, and the mold adjustment time is long, and the frequency of spare parts is high, which increases the mold maintenance cost and affects the production efficiency. In addition, the flatness is affected by the residual stress of the material. impact, poor dimensional stability

Embodiment Construction

[0018] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0019] The most critical idea of ​​the present invention is that: the present invention prints marking points 2 on the raw material tape to manufacture the body 1, and the shield frame with the depression or protrusion can effectively ensure the flatness.

[0020] see figure 1 , the manufacturing process of the shielding case frame of the present invention comprises the following steps:

[0021] S1. Print marking points on the raw material tape, the marking points are depressions or protrusions arranged at intervals to prepare blanks;

[0022] S2. Open holes on the edge of the blank that needs to be stretched and bent.

[0023] It can be seen from the above description that the beneficial effect of the present invention lies in that the ...

Abstract

The invention discloses a manufacturing process of a shielding cover frame, which comprises the following steps: S1, printing marks on a raw material tape entering a mold, where the marks are recesses or protrusions arranged at intervals, to prepare a blank; S2, Holes are made at the edges of the blank that need to be stretched and bent. Also disclosed is a shielding cover frame, which includes a body, the surface of the body is provided with a number of imprinted points, and the imprinted points are depressions or protrusions, and the stretched and bent edges of the surface are provided with punching holes. The shielding cover frame and the manufacturing process thereof of the present invention make the flatness of the product more stable, and can effectively reduce the maintenance cost of the mould.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a shielding cover frame and a manufacturing process thereof. Background technique [0002] Modern electronic products tend to be thinner and lighter, and have higher and higher requirements for electronic products, especially for the stability of electronic equipment hardware and performance. At present, many components adopt the surface welding process (SMT) to install the Shield Frame (shield frame), and this process has high requirements on the flatness of the Shield Frame (shield frame). [0003] At present, Shield Frame products are in the process of production. Because the Shield Frame products are relatively large, the mold process is a blanking and bending structure, and then the flatness is adjusted through screws. The main disadvantage is that the stamping die only considers the screw structure to adjust the flatness. However, when this solution is ad...
