The motor box 117 protects the storage motor 118 and the box door can be opened for repair and replacement when the storage motor 118 is damaged.

[0030] When hot pressing the light-guiding film, the rolled light-guiding film is passed on the placement shaft 106, and the light-guiding film is pulled until the light-guiding film is laid flat on the mold 104, and the light-guiding film is fixedly connected to the connecting soft film 108 by gluing, and the hot pressing template 103 and the two hydraulic cylinders 102 are started, and the two hydraulic cylinders 102 press the hot pressing template 103 downward to hot press the part of the light-guiding film located on the mold 104. After the hot pressing is completed, the two hydraulic cylinders 102 are started in the reverse direction, and the two hydraulic cylinders 102 drive the hot pressing mold The plate 103 is reset, and the storage motor 118 and the fan 119 are started. The storage motor 118 drives the drum shaft 110 to rotate, and with the assistance of the sliding bar 120, drives the storage roller 111 to rotate. When the storage roller 111 rotates, it pulls the light guide film through the connecting film 108, so that the subsequent part of the light guide film moves to the top of the mold 104 for hot pressing, and the hot pressed light guide film is stored; at the same time, because the two fixing bolts 115 fix the matching frame 112 on the moving rail 113, With the assistance of the fastening bolts 116, the rotating shaft 110 drives the rotating shaft 114 to rotate, so that the rotation of the rotating shaft 110 is more stable, and when the light guide film passes through the fan frame 107, the fan 119 is blown away by the residual heat, so as to cool the light guide film to prevent deformation and damage when the light guide film is stored; after the whole section of the light guide film is processed, the two fixing bolts 115 and the fastening bolts 116 are screwed out, so that the matching frame 112 can move along the moving rail 113, and the matching frame 112 is pulled along the moving rail 113, and the matching frame 112 is The combined frame 112 is assisted by the four universal wheels to move away from the storage frame 109, and the rotating shaft 114 is separated from the rotating drum shaft 110. At this time, the stored light-guiding film can be removed from the rotating drum shaft 110 along the sliding sheet 120 together with the storage roller 111 and the connecting soft film 108, and transported to the next process. This avoids the problem that the prior art can only hot-press the light-guiding film in the mold 104, but cannot directly hot-press a complete section of light-guiding film, and needs to be performed in multiple times, resulting in low production efficiency. The light-guiding film is continuously hot-pressed to improve the production efficiency.
