OCA disassembling platform

Abstract

The invention discloses an OCA disassembling platform, and relates to the technical field of machinery. Comprising a control box, a freezing device is arranged on the control box and comprises a linear motor, the linear motor is fixedly installed on the inner wall of the top of the control box, the output end of the linear motor is fixedly installed on the top of a push rod, and the push rod penetrates through and is slidably installed at the bottom of the control box; the bottom of the push rod is rotationally installed on the top of a first rotating rod, the bottom of the first rotating rod is rotationally installed on the top of a connecting rod, and the connecting rod is fixedly installed on the outer wall of the nozzle. According to the OCA disassembling platform, through the arrangement of the freezing device, when a freezing method is needed for disassembling, a linear motor and a nozzle are started to start working, the spraying dry ice cooling operation of the nozzle can be diffused from the center of a workpiece to the two sides, in this way, concentrated cooling of the nozzle is high in pertinence, and the efficiency of concentrated cooling is high; and the disassembly temperature can be reached without repeated freezing, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an OCA dismantling platform. Background technique [0002] OCA refers to a special adhesive used to bond transparent optical components (such as lenses, etc.). It is required to be colorless and transparent, with a light transmittance above 95%, good bonding strength, curable at room temperature or medium temperature, and have the characteristics of small curing shrinkage. OCA optical adhesive is one of the important raw materials for touch screens. It is made of optical acrylic adhesive without substrate, and then laminated with a layer of release film on the upper and lower layers. It is a double-sided adhesive tape without substrate material. It is the best adhesive for touch screen. Its advantages are clarity, high light transmittance (total light transmittance >99%), high adhesion, high weather resistance, water resistance, high temperature resistance, UV resistance...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the process of OCA dismantling, there is a freezing method for dismantling. Dry ice is used to place the workpiece in special ultra-low temperature equipment for a certain period of time, and the OCA will automatically detach due to cooling and solidification and loss of physical viscosity. However, the range cooling efficiency of the equipment is slow, which will make the dismantling time too long, resulting in low overall dismantling efficiency
