A glass substrate oca glue cleaning device

Abstract

The invention discloses a glass substrate OCA glue cleaning device, and relates to an optical glue cleaning device. The glass substrate OCA glue cleaning device is provided with a bottom frame, a pressing mechanism, a motion mechanism and a glue cleaning mechanism; a vacuum heating absorption table is placed in space of the bottom frame; the motion mechanism is provided with space motion XYZ three-directional driving modules; and the Z-axle driving module is provided with a compressible glue cleaning tool. A driven slide block and a driven slide block movable rail thereof are arranged on the inner side of the upper end surface of the bottom frame; and a pressing mechanism is arranged on the driven slide block. A modular structure is adopted; less OCA glue is placed at the front part of thecompressible glue cleaning tool head; a specific action procedure is written based on a PLC industrial personal computer; and the glue cleaning head is driven to realize cleaning of OCA glue on the surfaces of glass substrates in a glue extrusion deformation mode. Meanwhile, the pressing mechanism is added for regularly tearing the glue on the substrates to prevent deviation of the OCA glue in the cleaning process, so that the glue cleaning operation reliability is effectively improved.

Description

technical field [0001] The invention relates to an optical glue cleaning device, in particular to a glass substrate OCA glue cleaning device after a notebook computer display panel is thermally disassembled. Background technique [0002] The glass substrate is the basic component of the liquid crystal display screen of the notebook computer. It is glued together with the liquid crystal and polarizer through OCA optical glue to form the screen. The quality of the glass substrate has a huge impact on the liquid crystal display. The resolution, light transmittance, viewing angle and other indicators of the finished liquid crystal panel are closely related to the quality of the substrate glass used, and the production cost of the corresponding glass substrate is also relatively high. Therefore, When the LCD computer display screen is damaged, the recycling company thermally disassembles the display screen, cleans the surface of the glass substrate and supplies it to the maintena...

AI Technical Summary

Problems solved by technology

In the actual recycling process, most enterprises adopt the manual glue removal scheme. Workers put the disassembled glass substrate on a heating table and heat it to above 60°C, and manually clamp a certain glue to glue the OCA glue on the glass substrate. Cleaning, high labor intensity, low production efficiency, poor working environment

[0003] Correspondingly, there are also some glass substrate OCA glue cleaning devices on the market, such as the glue removal wheel type glue removal equipment corresponding to the Chinese patent CN 201620422523. Incomplete, more surface residue
