The bonding platform 5 is fixedly connected to the top of the bottom plate 4. Through the movable sleeve between the bottom plate 4 and the mounting groove 3, the installation and use of bonding platforms 5 of different specifications can be realized, and the maximum width of the bonding platform 5 is one-quarter shorter than the length of the roller 7, so as to facilitate the bonding of multi-layer OCA optical glues of different specifications and sizes.

[0031] When the roller 7 needs to be cleaned, the user controls the two micro motors 11 to operate, and the operation of the two micro motors 11 drives the two first screws 8 to rotate synchronously. The rotation of the two first screws 8 drives the two mounting frames 9 to move horizontally.
