The feeding pump 243 can transport the optical adhesive in the storage tank 242 to the feeding component 25 after power is turned on and started, so as to provide the feeding component 25 with the optical adhesive required for coating.

[0058] like Figure 10 As shown, the feeding assembly 25 includes a central pipe 251, a discharge plate 252 and a coating rotary rod 253. The central pipe 251 is connected to the bottom of the feeding pump 243, the discharge plate 252 is connected to the bottom of the central pipe 251, and the coating rotary rod 253 is rotatably connected to the output end at the bottom of the discharge plate 252. The rear side of the central pipe 251 is fixedly connected to the top of the adjusting triangle 221, and the bottom of the coating rotary rod 253 is connected to the top of the coating belt 223. By setting the feeding assembly 25, the central pipe 251 can cooperate with the discharge plate 252 and the coating rotary rod 253, and the adhesive delivered by the feeding pump 243 is delivered to the discharge plate 252 through the central pipe 251. The optical adhesive in contact with the coating rotary rod 253 can be evenly coated on the surface of the coating belt 223 by the rotation of the coating rotary rod 253 along the coating belt 223, providing a stable supply of optical adhesive for the coating belt 223 to coat the touch screen.

[0059] A brief description of the usage process: First, the processing mechanism 2 is connected to the remote control terminal and powered on and started. Then, the user operates the controllable structure in the processing mechanism 2 by controlling the remote control terminal. At this time, the adjustment motor 212 will drive the adjustment rod 213 to rotate, and the adjustment rod 213 will drive the adjustment triangle 221 to rotate together, and at the same time drive the conveying rod group 222 to rotate the coating belt 223 together until the front side of the coating belt 223 moves downward to the position of the touch screen, and then fill the storage tank 242 with optical adhesive, and then connect the storage tank 242 with the recovery pipe 241, and then the feeding pump 243 will pump the optical adhesive from the storage tank 242 into the central pipe 251, and the optical adhesive will contact the coating rod 253 through the discharge plate 252. When the conveying rotating rod group 222 drives the coating belt 223 to perform reciprocating motion, the coating belt 223 will drive the coating rotating rod 253 to rotate while moving, and the coating rotating rod 253 will evenly apply the optical adhesive on the surface to the surface of the coating belt 223 while rotating. The coating belt 223 will drive the optical adhesive to contact the touch screen and apply the adhesive to the surface of the touch screen. Thereafter, the coating belt 223 will move the excess adhesive to the scraper plate 231, and the scraper plate 231 will scrape the excess adhesive into the recovery box 232. As the amount of adhesive accumulated in the recovery box 232 increases, the electric suction pipe 233 will suck the adhesive into the recovery pipe 241 through negative pressure for recovery, and the recovery pipe 241 will send the adhesive back to the storage tank 242 for subsequent optical adhesive coating processing.
