Back-up roll for transmission of chip-on-film product

The invention relates to the technical field of chip-on-film product transmission, and discloses a support roller for chip-on-film product transmission, which comprises a mounting cylinder, and a plurality of annular support structures coaxial with the mounting cylinder are arranged on the mounting cylinder; the outer circle radius of the supporting structure is larger than that of the installation cylinder, the supporting structure comprises two edge supporting structures arranged at the two ends of the installation cylinder respectively and a plurality of middle supporting structures arranged between the two edge supporting structures, and detachable annular gaskets are arranged on the outer side walls of the middle supporting structures. Compared with the prior art, different supporting rollers do not need to be switched frequently, the equipment debugging time is shortened, and meanwhile abrasion of the supporting rollers and the axis caused by frequent switching of the supporting rollers is avoided. 本发明涉
