Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass production, in particular to a micro roller applied to the air-floating transmission of liquid crystal glass. Background Technique

[0002] G6-generation and above 8.5-generation liquid crystal glass inspection machines all adopt an air-floating transmission system. For example, an air-floating conveyor belt auxiliary wheel mounting mechanism (CN209097747U) applied by the inventor before. The air-floating transmission equipment has very high requirements for the warpage of glass. Generally, when the warpage of glass is within the range of 0.1 - 0.2 mm, it can be smoothly transmitted, and particle inspection, inclusion defect inspection, and edge grinding quality inspection can be carried out. However, the warpage of glass fluctuates in daily production. If the glass with a warpage within the range of 0.2 - 0.25 mm is also within the qualified product process control range, but when it is transmitted on the air-floating conveyor belt of the inspection machine, a clamping plate abnormality will occur, that is, the glass stops on a certain section of the air-floating conveyor belt, resulting in this piece of glass becoming a waste product and causing losses. Therefore, the inventor has re-proposed a micro roller applied to the air-floating transmission of liquid crystal glass. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a micro roller applied to the air-floating transmission of liquid crystal glass, and solves the problems raised in the above background technique.

[0008] Rolling balls, several rolling balls are arranged to roll between the outer roller ring and the inner roller ring;

[0009] A retaining ring, which can restrict the positions of several rolling balls.

[0010] Furthermore, two limiting rings are symmetrically connected to the outside of the outer roller ring, several limiting cross bars are connected between the two limiting rings, several limiting grooves are arranged on the inner wall of the protruding part, the protruding part is located between the two limiting rings, and the limiting grooves are clamped outside the limiting cross bars.

[0013] Further, the outer ring of the roller, the inner ring of the roller, and the retaining ring are all made of polyether ether ketone, the rolling balls are of solid structure and are made of ceramic material.

[0014] Further, a shaft hole is provided through the middle of the inner ring of the roller.

[0015] The utility model provides a micro roller applied to the air-floating transmission of liquid crystal glass. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The micro roller applied to the air-floating transmission of liquid crystal glass can correct the warping and fluctuation of the glass, effectively solve and prevent the problem of scratching defects of the air-floating strip of the inspection machine, avoid causing scratched defective products, prevent the glass from contacting the air-floating pad of the air-floating conveyor belt, and avoid the problem of abnormal transmission card plate. It can ensure the smooth detection of the inspection machine equipment, avoid major production abnormalities such as broken plates during the inspection of particles, inclusion defects, and edge grinding defects, resulting in production interruption, loss of operation time for manual cleaning of broken glass and sanitation cleaning, and reduction of equipment operation rate;

[0017] 2. For the micro roller applied to the air-floating transmission of liquid crystal glass, the protruding part in contact with the glass can be disassembled and assembled with the outer ring of the roller. When the protruding part is scratched and damaged by the glass and needs to be replaced, the protruding part can be directly peeled off and a new protruding part can be installed, without replacing the entire roller, thus reducing the production cost.
