Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a clamp used for assembling mobile phone keys. Background Art

[0002] As the mobile phone industry enters the era of low profits, mobile phone buttons need to be not only exquisite in appearance but also low in cost to be competitive. Therefore, manufacturing assembly fixtures to place each button and then assembling the buttons on the mobile phone at one time can shorten the overall product production process and greatly improve production efficiency.

[0003] The existing assembly fixture for assembling mobile phone keys still has the following problems: the general assembly fixture is composed of injection-molded pure PC hard glue or bakelite handboard, and the gap ribs made are generally above 0.15mm, and the gap degree of the gap ribs determines the spacing degree between the keycaps. The keycap spacing of 0.15mm is a bit large, which makes the appearance of the mobile phone keycaps less delicate, and the hard glue is not easy to place the keys, and it is also easy to scratch the keycaps. In addition, the hard glue has no strength, and the gap ribs are easier to collapse, making it difficult to assemble the keycaps on the fixture. Utility Model Content

[0005] The purpose of the utility model is achieved in the following way: a clamp for assembling mobile phone keys, comprising a shell, the shell is provided with acupoints for assembling mobile phone keycaps, the surface of the acupoints is provided with a TPU soft rubber layer, the TPU soft rubber layer is provided with vertical ribs and transverse ribs, and the vertical ribs and transverse ribs are staggered with each other.

[0006] In the above description, as a further solution, the surface of the acupuncture point is provided with an ejection hole, and the TPU soft rubber layer is provided with a matching hole for matching with the ejection hole.

[0007] In the above description, as a further solution, the vertical ribs and the transverse ribs are provided in plurality, and the plurality of vertical ribs and the plurality of transverse ribs are interlaced to form an assembly position.

[0008] In the above description, as a further solution, the vertical ribs and the transverse ribs are both vertically arranged on the TPU soft rubber layer.

[0009] In the above description, as a further solution, a positioning column is provided on the edge of the shell.

[0010] In the above description, as a further solution, there are a plurality of acupoints, and the acupoints are evenly arranged on the shell.

[0023] See also Figure 1-7 A clamp for assembling mobile phone keys is specifically implemented, comprising a shell 1, on which acupuncture points 2 for assembling mobile phone keycaps 11 are provided, a TPU soft rubber layer 3 is provided on the surface of the acupuncture points 2, and vertical ribs 4 and transverse ribs 5 are provided on the TPU soft rubber layer 3. The vertical ribs 4 and the transverse ribs 5 are staggered with each other, and the gaps between the vertical ribs 4 and the transverse ribs 5 are both 0.1-0.12mm, and the vertical ribs 4 and the transverse ribs 5 are both gap ribs.

[0024] Generally, when using an injection molding fixture, hard plastics such as PC are used for injection molding. However, due to the poor fluidity of hard plastic materials such as PC, it is easy to fail to be molded, and the gap between ribs is generally above 0.15mm. At the same time, hard plastic will easily scratch the keycap 11. In addition, the ribs are too narrow, and the hard plastic has no strength and is easy to collapse. The TPU material used in the TPU soft rubber layer 3 has good fluidity, and the 0.12mm ribs can be fully molded by injection molding, which is conducive to injection molding. The vertical ribs 4 and horizontal ribs 5 with a width of 0.1mm can be injection molded. In addition, the TPU soft rubber layer 3 has good wrapping properties for the keycap 11, which can prevent the keycap 11 from being skewed. After the keycap 11 is assembled, the gaps between the keycaps 11 will be relatively uniform, with a high yield and a good appearance.

[0025] Specifically, the surface of the acupuncture point 2 is provided with an ejection hole 6, and the TPU soft rubber layer 3 is provided with a matching hole 7 for matching with the ejection hole 6. The provision of the ejection hole 6 and the matching hole 7 facilitates the keycap 11 to be ejected from the TPU soft rubber layer 3 by other ejection devices after the keycap 11 is assembled. The TPU soft rubber layer has good wrapping properties for the keycap 11, and after the assembly is completed, the keycap 11 is not easy to be removed from the TPU soft rubber layer.

[0026] In this embodiment, a plurality of vertical ribs 4 and a plurality of transverse ribs 5 are provided, and the plurality of vertical ribs 4 and the plurality of transverse ribs 5 are interlaced to form an assembly position 8 .

[0027] Specifically, the vertical ribs 4 and the transverse ribs 5 are both vertically arranged on the TPU soft rubber layer 3 .

[0028] In this embodiment, a positioning column 9 is provided on the edge of the shell 1. The setting of the positioning column 9 facilitates the positioning of the upper and lower clamps during assembly. During assembly, the upper and lower clamps are matched, the upper clamp is used to place the keycaps, that is, the clamp of the utility model, and the lower clamp is used to place the silicone. There are corresponding ejection holes on the edge. After the silicone is glued, the upper and lower clamps are matched to complete the assembly.

[0029] In this embodiment, the acupuncture points 2 are provided in a plurality, and the plurality of acupuncture points 2 are evenly arranged on the housing 1. The number of acupuncture points 2 is determined by the enterprise.

[0030] In this embodiment, a mark 10 is provided on the edge of the housing 1. The mark 10 is provided so as to correspond to the position of the key cap 11 to prevent the wrong key from being pressed.

[0031] In this embodiment, the main body of the shell 1 is first made of PC material, and then the TPU material is used to directly inject the TPU soft rubber layer 3 into the shell 1. After the injection molding, the PC and TPU are bonded together, so it is called two-color injection molding. Two-color means using two materials (not colors).

[0032] The injection molding process of the embodiment of the utility model is as follows: the housing 1 is injection molded with PC, and the TPU soft rubber layer 3 is directly injection molded inside the housing 1 by using the material TPU. After the injection molding, the PC and TPU are bonded together.

[0033] The above contents are further detailed descriptions of the present invention in combination with specific further embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
