In this embodiment, the clamping unit mainly includes a clamping mounting plate 112, a clamping cylinder 113 and a clamping head 114, the clamping mounting plate 112 is fixedly mounted on the rotary mounting plate 108, so that the clamping unit can move synchronously with the vacuum adsorption unit, the clamping cylinder 113 is fixedly mounted on the clamping mounting plate 112, the clamping head 114 is fixedly mounted on a cylinder rod of the clamping cylinder 113, the clamping head 114 can be pushed by the clamping cylinder 113 to extend and retract, and the clamping head 114 is arranged corresponding to the vacuum suction head 111.

When the device is used, the device is matched with a vacuum chuck (not shown in the figure) at the lower part for use, a shading film or a reflecting film is placed on the vacuum chuck, a vacuum suction head 111 adsorbs a release film on the shading film or the reflecting film, a rotary cylinder 109 drives a vacuum head mounting rod 110 to rotate, the vacuum head mounting rod 110 drives the vacuum suction head 111 to rotate, the release film adsorbed by the vacuum suction head 111 rotates together and faces one side of a clamping head 114, so that the release film is separated from one end of the shading film or the reflecting film, the clamping cylinder 113 pushes the clamping head 114 to move, so that the clamping head 114 clamps the release film together with the vacuum suction head 111, a motor 100 drives a belt 103 to move, the belt 103 pulls a sliding block 106 to move along a sliding rail 99, the sliding block 106 drives the vacuum suction head 111 and the clamping head 114 to move synchronously, so that the whole release film is torn off from one side, and after the tearing off is finished, the vacuum suction head 111 and the clamping head 114 stop working simultaneously, the torn release film naturally drops into the waste bin, the motor 100 drives the belt 103 to move in the reverse direction, the belt 103 pulls the slider 106 to move along the sliding rail 99, and the slider 106 drives the vacuum suction head 111 and the clamping head 114 to reset to prepare for the second operation.

In the present invention, since the light shielding film and the reflective film are respectively bonded to the upper and lower sides of the light guide film, the light shielding film protective release paper removing mechanism 7 and the reflective film protective release paper removing mechanism 8 are opposite in direction and are installed in opposite directions, but the structure is the same, that is, the release paper of the reflective film is located below, and the release paper of the light shielding film is located above.

When the invention is used, the light guide film is peeled off by the light guide film feeding mechanism 2 and is conveyed to the first laminating mechanism 9 by the conveying belt 16, the reflective film is placed on the reflective film feeding mechanism 4, a piece of reflective film is grabbed by the reflective film feeding mechanism 4 and is conveyed to the reflective film aligning and shaping mechanism 6 by the third conveying mechanism, the reflective film is aligned and adjusted by the reflective film aligning and shaping mechanism 6 and is conveyed to the reflective film protecting and releasing paper tearing mechanism 8 by the fourth conveying mechanism, the reflective film protecting and releasing paper is torn off by the reflective film protecting and releasing paper tearing mechanism 8, after tearing off, the reflective film is placed on the first laminating mechanism 9 and then is conveyed to the conveying belt 16, the light guide film and the reflective film are laminated together, meanwhile, the light shielding film is placed on the light shielding film feeding mechanism 3, a piece of light shielding film is grabbed by the light shielding film feeding mechanism 3, the light guide film is conveyed to a photomask aligning and shaping mechanism 5 through a first conveying mechanism, the photomask aligning and shaping mechanism 5 is used for aligning and adjusting the photomask, then the photomask is conveyed to a photomask protecting release paper tearing mechanism 7 through a second conveying mechanism, the photomask protecting release paper tearing mechanism 7 is used for tearing the photomask protecting release paper, after the photomask is torn, the photomask is placed on a second laminating mechanism 10, then the light guide film with the reflecting film attached is conveyed to the second laminating mechanism 10 to be attached to the photomask, finally the product is conveyed to a blanking mechanism 11 through a fifth conveying mechanism, and the product is stacked to form a finished product.

The light guide film feeding mechanism, the shading film/reflecting film feeding mechanism, the alignment shaping mechanism and the protective release paper tearing mechanism are matched to work, so that the effect of automatically laminating the light guide film, the shading film and the reflecting film in the keyboard backlight module can be realized.
