Description

Technical Field

[0001] This utility model relates to the field of mobile phone manufacturing technology, and in particular to a vertical cold pressing fixture for sealing silicone pads for mobile phone speakers. Background Technology

[0002] In the mobile phone manufacturing process, the NG defect rate of the airtightness test of the mobile phone frame is high. Simple hole sealing test shows that most defects are due to speaker hole leakage. Further fluorescent ink penetration test shows that there is a through point of penetration in one corner of the adhesive sealing ring of the speaker sealing silicone pad. This is due to uneven cold pressing force and incomplete activation of the adhesive. This leads to a decrease in the production yield and efficiency of the side hole airtightness test. Therefore, a vertical cold pressing fixture for the mobile phone speaker sealing silicone pad was designed. Utility Model Content
