Problems solved by technology

[0002] Electronic devices such as mobile phones usually need to install antennas inside their casings. The existing antenna installation is usually to use pressing equipment to press the world on the casing of the electronic device. In order to make the electronic device have a better user experience, It is usually necessary to arrange multiple antennas. For example, at this stage, most mobile phones are equipped with antennas on the upper and lower ends of their housings. In view of this situation, the current antenna installation method is to use a press-fit device to place antennas on the upper and lower ends of the housing. Press one of the antennas at one end, and then transfer to the next station to press the other antenna to the other end of the housing through the pressing device, which leads to low efficiency in the installation process of the antenna

Embodiment 1

[0035] A mobile phone antenna synchronous pressing process, the mobile phone shell is placed on the working platform for fixing, and the upper and lower ends of the mobile phone shell are used for pressing the antenna, so that the two antennas are respectively fitted and fixed on the mobile phone shell top and bottom ends.

[0036] Wherein, an ultra-thin double-sided adhesive tape with a release film peeled off is compounded on the side where the antenna and the mobile phone casing are bonded, the thickness of the ultra-thin double-sided adhesive tape is less than 20 μm, and the ultra-thin double-sided adhesive tape is made by the following method have to:

[0037] (1) On the front of the first PET release film, coat one deck of UV curing acrylic paint, then carry out UV curing, form the acrylic carrier layer;

[0038] (2) coating one deck of UV curing acrylate pressure-sensitive adhesive on the front side of the acrylate carrier layer to form the first pressure-sensitive adh...

Embodiment 2

[0055] The difference between this embodiment and embodiment 1 is:

[0056] Wherein, the thickness of the acrylate carrier layer is 2 μm, the thickness of the first pressure-sensitive adhesive layer is 7.5 μm, and the thickness of the second pressure-sensitive adhesive layer is 7.5 μm.

[0057] Wherein, the UV curing acrylic paint includes the following raw materials in parts by weight:

[0058]

[0059] The aliphatic urethane acrylate is Sartomer CN9110NS.

[0060] Wherein, the preparation method of the acrylate carrier layer is: aliphatic urethane acrylate, glycidyl methacrylate, methyl methacrylate, isobornyl acrylate, dipentaerythritol pentaacrylate, TPO photoinitiator and 659 After the photoinitiator is mixed uniformly by weight, it is coated on the front side of the first PET release film, and then UV curing is carried out. The light energy of UV curing is 400mJ / cm 2 , The curing time is 10min.

[0061] Wherein, the UV curing acrylate pressure-sensitive adhesive co...

Embodiment 3

[0070] The difference between this embodiment and embodiment 1 is:

[0071] Wherein, the thickness of the acrylate carrier layer is 1 μm, the thickness of the first pressure-sensitive adhesive layer is 9.5 μm, and the thickness of the second pressure-sensitive adhesive layer is 9.5 μm.

[0072] Wherein, the UV curing acrylic paint includes the following raw materials in parts by weight:

[0073]

[0074] The aliphatic urethane acrylate is composed of Sartomer CN9110NS and Sartomer CN9025 in a weight ratio of 1:1.

[0075] Wherein, the preparation method of the acrylate carrier layer is: aliphatic urethane acrylate, glycidyl methacrylate, methyl methacrylate, isobornyl acrylate, dipentaerythritol pentaacrylate, TPO photoinitiator and 659 After the photoinitiator is mixed uniformly by weight, it is coated on the front side of the first PET release film, and then UV curing is carried out. The light energy of UV curing is 500mJ / cm 2 , The curing time is 6min.

Abstract

The invention relates to the technical field of mobile phone antennas, in particular to a mobile phone antenna synchronous pressing process. The process comprises the following steps that a mobile phone shell is placed on a working platform to be fixed, and the upper end and the lower end of the mobile phone shell are subjected to antenna pressing by using a pressing jig, so that the two antennasare attached and fixed to the upper end and the lower end of the mobile phone shell correspondingly. According to the process, the antenna pressing is performed on the upper end and the lower end of the mobile phone shell by using the pressing jig so that the pressing of the double antennas can be completed in one step without entering the next station, manual work can be replaced with mechanicalautomation, the operation precision can be enhanced, and the product reject ratio can be reduced.
