Problems solved by technology

[0002] The side button of the mobile phone is an important part of the mobile phone. After the production is completed, it must be assembled with other mobile phone parts to form the final product. Glue is needed during assembly. The side button of the mobile phone itself is small in size and shape. , the surface of the side keys of the mobile phone is easy to stick glue, the glue is easy to solidify and is not easy to clean, resulting in a decrease in the yield of the finished product, resulting in a large accumulation of defective products, wasting materials, and the defective products are generally processed through the following process: assembly → inspection of finished products → disassembly Glue spilled side key → treatment agent soaking treatment → re-inspect a single side key → assembly → inspection of the finished product, the cost of the treatment agent is high, easy to volatilize, and the number of one-time performance treatment is small, the cleaning cost is high and the cleaning efficiency is low, and further improvement is needed

Abstract

The invention discloses a process for improving mobile phone side key assembly defective products. The process includes the steps: (1) checking: checking assembled finished products, and disassemblingside keys with glue on surfaces; (2) glue softening: soaking the side keys with the glue on the surfaces in softening treatment liquid; (3) ultrasonic cleaning: placing the softened side keys into anultrasonic instrument with cleaning liquid, and cleaning the side keys; (4) drying: drying the ultrasonically cleaned side keys. The softening treatment liquid comprises, by weight, 16-23 parts of diethanol amine, 9-16 parts of sodium sulfate, 8-16 parts of alkylphenol ethoxylates, 15-26 parts of sodium dodecyl sulfate, 10-16 parts of sodium dodecyl benzene sulfonate, 8-12 parts of acetylacetic ether, 5-8 parts of citric acid, 1-2 parts of hydroxy propyl cellulose and 20-30 parts of deionized water.
