This device includes a heating furnace, a worktable, a feeding structure, and a gluing structure. The worktable has an opening, the feeding structure is located below the worktable, the gluing structure is fixedly mounted on the worktable, the heating furnace is placed on the worktable, and a limiting frame is fixedly mounted on the worktable within the opening. A guide plate is fixedly mounted on the limiting frame above the heating furnace. The feeding structure includes a base, a telescopic rod, a push plate, and a pusher. The base is located below the worktable, the telescopic rod is fixedly mounted on the base (multiple sets of telescopic rods are provided), the push plate is fixedly mounted on the output rod of the telescopic rod, and the push plate slides within the limiting frame.
