Embodiment Construction

[0007] The present invention will be further described below by specific examples.

[0008] As shown in the figure, the squeegee tool of the present invention includes a U-shaped groove 1, a wing plate 3 and a deflector 2. The wing plate is connected to the two side plates of the U-shaped groove and is inclined to the outside of the U-shaped groove. The deflector and the bottom plate of the U-shaped groove form an acute angle.

[0009] The height of the U-shaped groove of the squeegee tool is higher than the height of the glass diversion groove, the width of the U-shaped groove is smaller than the width of the glass diversion groove, the deflector of the squeegee tool, and the distance between the deflector and the U-shaped groove The acute angle between the bottom plates is 15°~30°, which can effectively introduce the resin glue. The squeegee tool includes a handle 4, which is connected to the U-shaped groove and forms an integral body with the two wing plates, which is conv...

Abstract

The invention provides an adhesive scraper tool and belongs to the technical field of adhesion of photovoltaic silicon ingots. According to the technical scheme, the adhesive scraper tool comprises a U-shaped channel, wing plates and a guide plate; the wing plates connected with two side plates of the U-shaped channel and tilt outside the U-shaped channel; the guide plate and a bottom plate of the U-shaped channel form an acute angle. When the adhesive scraper tool is in use, the U-shaped channel is locked in a glass guide channel containing resin adhesive, the resin adhesive is treated in time through the guide plate, and the wing plates on two sides form a temporary storage container of resin adhesive; the resin adhesive on the adhesive scraper tool is cleared after each single operation, the resin adhesive in the glass guide channel can be more effectively guided, bubbles generated in the adhering process can be effectively eliminated, initial solidification of the resin adhesive caused by long-term operation can be avoided, adhesion strength of the resin adhesive is decreased, and finally adhesion effect of the silicon ingots is influenced.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic silicon ingot bonding, and in particular relates to a glue scraping tool for cleaning resin glue in a glass diversion groove. Background technique [0002] In the silicon ingot slicing process, silicon ingot bonding is a key process before silicon material cutting and processing. When silicon ingots are bonded, resin glue is usually used to bond glass pads and silicon ingots. Resin glue is generally made of epoxy resin It is composed of two components with curing agent, which should be mixed in a certain proportion before use. During the adhesive bonding process, air bubbles will be generated and enter the adhesive surface. The air bubbles will turn over to the surface of the silicon ingot during the bonding process. After being pressured, the volume becomes smaller, and the pressure inside the air bubbles is extremely high. During the cutting process, there will be defects such as silicon ...
