Description

Technical Field

[0001] The utility model relates to the technical field of optical glass processing equipment, in particular to a circular AVG glue leveling and developing fixture. Background Art

[0002] Micro-nano gratings are currently made by working on periodic micro-nano structures on optical glass, and then homogeneously bonding them with anti-halation glass (AVG) to combine them into a whole. The current glue coating and development jig directly on the circular anti-halation glass (AVG) is suitable for 4 and 6-inch wafer jigs, which have the following disadvantages: the residual glue on the edge of the product during glue coating can easily contaminate the suction cup, and the developer and water can easily enter from the opening during development to contaminate the glue coating / development suction cup. Utility Model Content

[0003] The utility model aims to provide a circular AVG glue spreading and developing fixture which can closely match the AVG and glue spreading sucker and is easy to use.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A circular AVG coating and developing jig, comprising an AVG and a coating sucker;

[0006] The AVG comprises a bottom disc and a circular working sheet arranged on the surface of the bottom disc;

[0007] The glue-distributing suction cup comprises a top suction cup and a cylindrical connecting portion arranged at the bottom of the top suction cup. The surface of the top suction cup is provided with a vacuum suction hole and a plurality of grooves sunken downwards. The vacuum suction hole is connected with the groove, and the vacuum suction hole is connected with a vacuum equipment pipeline.

[0008] The bottom of the bottom disc is connected to the top suction cup by vacuum adsorption.

[0009] AVG is the abbreviation of anti-halo glass. This scheme directly operates periodic micro-nano structures on AVG, which can save three major steps, namely rolling edge, bonding, and cutting, and saves consumables (grinding head, bonding fixture, photoresist, etc.) at 3 sites. The bottom disk of AVG is vacuum adsorbed on the top of the glue-spreading suction cup, and the glue-spreading suction cup is connected to the cylindrical connecting part and rotates with the cylindrical connecting part. During vacuum adsorption, a vacuum suction hole is set to connect with the vacuum equipment to provide a vacuum environment. AVG is vacuum adsorbed and positioned by the glue-spreading suction cup and rotates under the drive of the glue-spreading suction cup, so that the excess glue, solvent, etc. on AVG can be thrown off or accelerated to evaporate under the action of centrifugal force.

[0010] As a preferred solution of the utility model, the vacuum suction hole is set at the center of the top suction cup, and the groove includes two circular grooves with the same center as the vacuum suction hole, and two linear grooves connected to the circular groove and passing through the vacuum suction hole. The circular groove of this solution is connected to the vacuum suction hole through two linear grooves that cross in a cross shape. Compared with grooves of other shapes, the groove shape of this solution can evenly distribute the vacuum suction force, so that the top suction cup and the bottom disc of the AVG can be tightly adsorbed and fixed in all directions.

[0011] As a preferred solution of the utility model, the diameter of the bottom disc is larger than the outer diameter of the top suction cup, and when the bottom of the bottom disc is connected to the top suction cup by vacuum adsorption, a hollow gap is provided between the edge of the bottom disc and the top suction cup. The effective area of ​​the actual contact between the AVG bottom disc and the top suction cup of this solution is smaller than the area of ​​the AVG bottom disc, so that the hollow gap between the edge of the AVG bottom disc and the top suction cup is not in contact, thereby avoiding contamination of the top suction cup when the glue flows down from the edge of the AVG bottom disc during the rotating glue spinning process.

[0012] As a preferred solution of the utility model, the cylindrical connecting part is connected to a rotating device. The AVG of this solution is adsorbed on the top suction cup to throw out excess glue and accelerate the volatilization of solvent through rapid rotation, and the rotating device is an existing device.

[0013] As a preferred solution of the utility model, a glue dripping port is provided above the glue-spreading suction cup. In this solution, after the AVG is adsorbed on the top suction cup, the glue liquid can be dripped onto the AVG through the glue dripping port, which can prevent the glue liquid from being lost during the transfer process.

[0014] Compared with the prior art, the utility model has the beneficial effects that the AVG and the glue-spreading suction cup can be closely matched, and the glue solvent will not be contaminated on the top suction cup to cause pollution during the process of rotating glue and solvent volatilization.
