In the coating process of the solar back plate, the device needs to adjust different coating glue widths according to different back plate sizes, so that the width of the coated glue is suitable for the back plate. In order to make the backboard adhere tightly, the thickness of the glue coated on the backboard needs to be adjusted according to actual requirements.
In order to solve the problem that the conventional backboard coating device is inconvenient to adjust the coating width and the coating thickness of the surface of the roller 2, the device is provided with the structures of the roller 2, the glue collecting plate 3, the two positioning blocks 41 and the two sealing sheets 42, glue is filled in the glue collecting groove between the two positioning blocks 41, and the control of the glue outlet width is realized in backboard coating by adjusting the distance between the two positioning blocks 41. The positioning block 41 is attached to the surface of the roller 2, and glue is prevented from entering between the positioning block 41 and the roller 2 in the rotating process of the roller 2. The sealing piece 42 is arranged to seal the positioning block 41 and the stripper plate 3.
The device, the collection gluey groove is from top to bottom space diminishing more and more. The glue injection assembly 5 is used for moving back and forth in the glue collecting groove between the two positioning blocks 41, and glue is injected into the glue collecting groove. Glue adheres to the surface of the roller 2 and moves downwards along with the roller 2, most of the glue is blocked by the glue collecting plate 3 in the rolling process of the roller 2, so that most of the glue is left in the glue collecting groove, and a glue layer adhered to the surface of the roller 2 is taken out of the glue collecting groove along with the roller 2 from a gap at the bottom of the glue collecting plate 3.

Glue is discharged from a glue outlet at the bottom of the glue collecting plate 3, and the glue collecting plate 3 can scrape and wipe the glue on the surface of the roller 2 uniformly, so that the thickness of the glue on the surface of the roller 2 is uniform, and the back plate can be coated uniformly when the glue is coated subsequently.
The bottom of the positioning block 41 is a glue outlet, and the control of the thickness of the glue outlet is essentially to control the distance between the bottom of the glue collecting plate 3 and the roller 2. The glue thickness adjusting component 7 can adjust the distance between the bottom of the glue collecting plate 3 and the roller 2, and plays a role in adjusting the glue thickness on the surface of the roller 2. In the adjusting process, the sealing piece 42 deforms to different degrees according to the pressure of the glue collecting plate 3, the sealing piece 42 is always in a pressing state with the glue collecting plate 3, and the sealing piece 42 is arranged to prevent glue from overflowing between the positioning block 41 and the glue collecting plate 3 all the time in the adjusting of the thickness of the glue.
The device is convenient to adjust the glue width and the glue thickness of the glue, and the glue width and the glue thickness are not influenced by each other.
The glue guiding assembly 6 comprises a scraping knife 61 arranged below the roller 2 and a scraping block 62 integrally arranged on one side below the scraping knife 61, the scraping knife 61 is attached to the roller 2, glue on the surface of the roller 2 is scraped at the edge of the scraping knife 61, the scraping block 62 is integrally arranged below the edge of the scraping knife 61, and the scraping block 62 guides the glue scraped at the edge of the scraping knife 61 to the backboard and smoothes the glue on the backboard.
In order to solve the problem that the excessive glue is scraped when the coating that current backplate coating device exists, cause the glue extravagant, this device has set up scraper 61 and has scraped the structure of piece 62, uses scraper 61 to scrape roller 2 surface glue, passes through the piece 62 coating of scraping on the backplate with glue, has made full use of roller 2 surface glue for roller 2 surface does not have excessive glue to remain, has effectively avoided the glue extravagant. The spreading action of the scraping block 62 facilitates uniform application of glue to the surface of the backing plate.
