[0077] After the flipping and picking component 8 drives the conduit to flip, the X-axis driving component 31, the Y-axis driving component 33, and the Z-axis driving component 34 of the first multi-dimensional adjustable picking component 3 cooperate to drive the suction cup 35 to move to the light guide plate. The suction cup 35 sucks. The X-axis driving component 31, the Y-axis driving component 33, and the Z-axis driving component 34 drive the light guide plate that has been sucked to move to the adjustable position calibration component 2 for position detection. After detection, the X-axis driving component 31, the Y-axis driving component 33, the R-axis driving component 36, and the Z-axis driving component 34 cooperate to adjust the feeding orientation of the light guide plate, and send the light guide plate to the feeding position for feeding.

[0078] In some embodiments, please refer to the attached instructions Figures 1 - 5, the reflector loading component includes a second winding component 9, an unwinder 10, a deviation rectifier 11, a second peeling and supporting component 15, a second multi-dimensional adjustable material taking component 16 and a second guiding and pressing component 17. The unwinder 10 and the second winding component 9 are installed at the front end of the left side of the workbench 1, the unwinder 10 is located above the second winding component 9, and the workbench 1 is connected with a deviation rectifier 11, a second guiding and pressing component 17, a second peeling and supporting component 15 and a second multi-dimensional adjustable material taking component 16 behind the unwinder 10. The driving end of the second multi-dimensional adjustable material taking component 16 moves above the second peeling and supporting component 15;

[0079] The structure of the second multi-dimensional adjustable material taking component 16 is the same as that of the first multi-dimensional adjustable material taking component 3, and the two are arranged oppositely;

[0080] The structure of the second guiding and pressing component 17 is the same as that of the first guiding and pressing component 5; the structure of the second winding component 9 is the same as that of the first winding component 7;

[0081] The first rotating roller 72, the fixed peeling plate 73, the second rotating roller 74 and the side plate 75 of the second winding component 9 correspond to the first rotating roller 72, the fixed peeling plate 73, the second rotating roller 74 and the side plate 75 of the first winding component 7 in terms of installation positions one by one, and the winder 71 of the second winding component 9 is installed on the outside;

[0082] The adjustable position calibration component 2 is located behind the second peeling and supporting component 15;

[0083] The release film roll containing the reflective sheet is placed on the unwinder 10. The end of the release film roll containing the reflective sheet passes through the deviation rectifier 11, the second guiding and pressing assembly 17, and the second peeling and supporting assembly 15 and is then connected to the second winding assembly 9. The first winding assembly 7 drives the release film to move along the top of the deviation rectifier 11, the second guiding and pressing assembly 17, and the second peeling and supporting assembly 15. The release film drives the reflective sheet to move along the top of the deviation rectifier 11, the second guiding and pressing assembly 17, and the second peeling and supporting assembly 15. The deviation rectifier 11 corrects the deviation of the release film containing the reflective sheet. The second guiding and pressing assembly 17 detects the position of the reflective sheet. When it detects that the reflective sheet moves to the set position, the second winding assembly 9 stops winding. At the same time, when the reflective sheet moves to the top of the second peeling and supporting assembly 15, the second guiding and pressing assembly 17 presses the release film to prevent offset inside. The adjustable position calibration assembly 2 calibrates the position of the light-shielding sheet at the rear end of the fixed composite support assembly 13. The second multi-dimensional adjustable material taking assembly 16 sucks and moves the reflective sheet on the second peeling and supporting assembly 15 to the second peeling and supporting assembly 15 for peeling treatment. The second multi-dimensional adjustable material taking assembly 16 drives the sucked reflective sheet to the adjustable position calibration assembly 2 behind the second peeling and supporting assembly 15 for azimuth detection. After detection, the second multi-dimensional adjustable material taking assembly 16 adjusts its own movement and feeding posture to suck the reflective sheet according to the set lower position, realizing the standardized alignment of the light-shielding sheet and the reflective sheet, which is beneficial to the accurate feeding of the reflective sheet; in addition, the wound release film can be reused, reducing the use cost, energy saving and environmental protection.
