[0036] First briefly describe the workflow of the present invention:

[0037] First, the shading film stripping device strips the shading film 101 from the material strip A201, the reflective film stripping device 2 strips the reflective film 102 from the material strip B202, and the light guide film stripping device 3 strips the light guide film 103 from the material strip C203 (the shading film stripping device, the light guide film stripping device, and the reflective film stripping device are performed independently);

[0038] Second, the backlight module laminating workbench receives the light shielding film 101 peeled off from the material strip A201 by the light shielding film peeling device;

[0041] Now a detailed introduction is given to the light-shielding film stripping device, the light-reflecting film stripping device, the light-guiding film stripping device, the backlight module laminating workbench and the film transfer and laminating device respectively.

[0042] like Figure 6-Figure 9As shown in the figure, in this embodiment, the light-shielding film peeling device 1 is used to peel the light-shielding film 101 from the wound material tape A201. The light-shielding film peeling device 1 is arranged on the frame 10 at the light-shielding film unwinding unit 11 for outputting the material tape A201. A plurality of light-shielding films 101 are arranged at intervals on the material tape A201. Along the conveying direction of the material tape A201, an adaptive buffer mechanism A12, a light-shielding film peeling mechanism 13, an adaptive buffer mechanism B14, and a waste tape winding unit A15 are sequentially arranged on the frame 10. A light-shielding film adsorption and transfer assembly 16 is arranged at the tail of the light-shielding film peeling mechanism 13 on the frame 10. The light-shielding film adsorption and transfer assembly 16 includes a transfer frame 161 slidably connected to the frame 10. The transfer frame 161 is in an inverted "U" shape, so that the transfer frame 161 can slide back and forth above the light-shielding film peeling mechanism 13. A driver C for driving the movement of the transfer frame 161 is arranged on the frame 10. An adsorption seat 162 is slidably connected to the upper part of the transfer frame 161 in the vertical direction. An adsorption head assembly 163 for adsorbing the light-shielding film 101 is arranged on the adsorption seat 162. A cylinder A164 for driving the up and down movement of the adsorption seat 162 is also arranged on the transfer frame 161. By arranging the light-shielding film adsorption and transfer assembly at the tail of the light-shielding film peeling mechanism, the light-shielding film adsorption and transfer assembly can assist in peeling the light-shielding film from the material tape A, and at the same time, it is also convenient for the transfer of the light-shielding film. It has the advantages of simple structure, low cost, and high efficiency.

[0043] Among them, the shading film stripping mechanism 13 includes a stripping seat 131 slidably connected to the frame 10, and the frame 10 is provided with a stripping seat driving device 132 for driving the stripping seat 131 to move back and forth along the conveying direction of the material strip A201. The stripping seat 131 includes a stripping seat bottom plate 1311 slidably connected to the frame 10, and the two sides of the stripping seat bottom plate 1311 are respectively provided with stripping seat side plates 1312, and the tops of the two stripping seat side plates 1312 are provided with stripping plates 1313, and the tops of the stripping plates 1313 are provided with a supporting surface 13131, and one end of the stripping plate 1313 is provided with a stripping surface 13132 intersecting with the supporting surface 13131, and an auxiliary guide wheel 1314 is provided between the two stripping seat side plates 1312, and the auxiliary guide wheel 1314 is located below the stripping plate 1313, and the frame 10 is provided with two groups of stripping seats for conveying the material strip A201. 1 is locked on the frame 10, one group of the material belt locking components A17 is located at the front side of the stripping seat 131, and the other group of the material belt locking components A17 is located at the rear side of the stripping seat 131, and the stripping seat 131 can move back and forth between the two groups of material belt locking components A17; the light shielding film stripping mechanism first locks the material belt on the frame through the material belt locking components A on both sides of the stripping seat, and then the light shielding film adsorption transfer component moves to the top of the light shielding film and adsorbs the light shielding film, and then the stripping seat moves backward under the action of the stripping seat driving device; when the stripping seat moves to the end, the light shielding film is completely stripped off from the material belt; with this design, the light shielding film is always in a relatively static state when stripping, which can ensure that the light shielding film is always flat and avoid deformation of the light shielding film. In addition, with this stripping method, the stripping force is relatively light, which can also avoid deformation of the light shielding film.

[0044] The material tape locking assembly A is used to stop the material tape so as to peel off the shading film from the material tape. In this embodiment, the material tape locking assembly A17 includes a pad 171 arranged on the frame 10, and the frame 10 is provided with a pressure block 172 that cooperates with the pad 171 to lock the material tape A201 on the pad 171, and the frame 10 is provided with a locking cylinder 173 that drives the pressure block 172 to move.

The adaptive buffer mechanism A connects the guide roller to two sliders slidably connected to the guide rod, so that the guide roller can move up and down along the guide rod; when the length of the material tape is too long, the guide roller will fall under the action of gravity, and when it falls to the lowest position, the light-blocking sheet will trigger the second photoelectric sensor to respond, thereby controlling the light-shielding film unwinding unit to stop unwinding; when the length of the material tape is too short, the material tape will move upward with the guide roller, and when it moves to the highest position, the light-blocking sheet will trigger the first photoelectric sensor to respond, thereby controlling the light-shielding film unwinding unit to continue unwinding, thereby achieving buffering of the material tape.

[0046] The reflective film stripping device 2 is provided on the frame 10 as a reflective film unwinding unit for outputting the material strip B202, on which the material strip B202 is provided with a plurality of reflective films 102 at intervals; the frame 10 is provided with an adaptive buffer mechanism C, a reflective film stripping mechanism, an adaptive buffer mechanism D and a waste tape reeling unit B in sequence along the conveying direction of the material strip B202; the light-guiding film stripping device 3 is provided on the frame 10 as a light-guiding film unwinding unit for outputting the material strip C203, on which the material strip C203 is provided with a plurality of light-guiding films 103 at intervals; the frame 10 is provided with an adaptive buffer mechanism E, a light-guiding film stripping mechanism, an adaptive buffer mechanism F and a waste tape reeling unit C in sequence along the conveying direction of the material strip C203.

With this design, the adsorption head has a downward elastic force through the elastic force of the spring, and when the backlight module adsorption assembly adsorbs the backlight module, no rigid pressure is generated on the backlight module, thereby avoiding mechanical damage to the backlight module.

[0053] like Figure 4 and Figure 5 As shown, in the operation of laminating the light-guiding film to the light-reflecting film and laminating the light-shielding film to the light-guiding film, it is necessary to position the light-reflecting film, the light-guiding film and the light-shielding film to ensure the accuracy of lamination; for this purpose, a first position recognition sensor 81 for identifying the position of the light-shielding film 101 relative to the left adsorption component 45 or the right adsorption component 48 is provided on the rack 10, a second position recognition sensor 82 for identifying the position of the light-guiding film 103 relative to the adsorption component A54 is provided on the rack 10, and a third position recognition sensor 83 for identifying the position of the light-reflecting film 102 relative to the adsorption component B55 is provided on the rack 10.
