Embodiment Construction

[0017] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0018] combine Figure 1 to Figure 3 As shown, a 3D4R mobile phone case jig includes a jig body 1, the upper part of the jig body 1 is provided with a workpiece groove 2 for placing the mobile phone casing, and a plurality of air holes 3 are opened in the workpiece groove 2, and the air holes 3 are connected up and down. When pumping air at the lower part of the jig body 1, air can be pumped into the workpiece groove 2 through the air hole 3, and the bottom of the workpiece groove 2 is of a rough design, so that the air extraction process will not be affected after...

Abstract

The invention discloses a 3D4R mobile phone shell jig which comprises a jig body. A workpiece groove used for placing a mobile phone shell is formed in the upper portion of the jig body, a plurality of air holes are formed in the workpiece groove, the jig further comprises a cover plate used for holding a membrane material, a through hole is formed in the middle of the cover plate to enable the cover plate to form a ring-shaped structure, when the cover plate covers the upper portion of the jig body, the vertical projection of the inner ring of the cover plate covers at least the upper end face of the R-angle structure of the mobile phone shell, and a gap is reserved between the lower opening edge of the inner ring of the cover plate and the upper end face of the R-angle structure of the mobile phone shell. The jig has the advantages that the cover plate structure is additionally arranged on the laminating jig, the lamination mode is changed into gradual lamination from the middle to the periphery through ingenious structural improvement, the phenomenon that bubbles appear on the inner surface of the mobile phone shell after lamination is avoided, the tight lamination at the R-angle position of the mobile phone shell is particularly ensured, and the vacuum lamination process of the 3D4R mobile phone shell is really realized.

Description

technical field [0001] The invention relates to the technical field of mobile phone shell processing equipment, in particular to a 3D4R mobile phone shell jig. Background technique [0002] The mobile phone protective case not only enhances the aesthetics of the mobile phone as an ornament, but also protects the mobile phone, playing the role of anti-drop, anti-scratch, waterproof and shockproof. With the upgrading of mobile phone case products, various three-dimensional (3D) mobile phone cases have appeared on the market. The four sides and four corners of the mobile phone case have R-angle structures (that is, approximately 1 / 4 circle) Curved flanging structure, collectively referred to as 4R), this type of mobile phone case (that is, 3D4R mobile phone case) can not only realize the all-round wrapping of the mobile phone, but also fit seamlessly with the mobile phone, with outstanding protection and aesthetic effects. The more consumers love it. [0003] When the mobile ...
