[0028] Specifically, in use, first place the backlight plate on the plurality of conveying rollers 100 on the box body 1, convey it through the plurality of conveying rollers 100, and then perform cutting. At the same time, the debris generated by the cutting will be blown away by the plurality of blades 18 on the plurality of rotating shafts 17 in the first notch 19 on the placing plate 15, avoiding the debris from affecting the subsequent cutting and thus affecting the accuracy of the backlight plate.

[0029] In the above solution, the conveying of the backlight plate is realized through the plurality of conveying rollers 100 on the box body 1. The fixing plate 38 in the blowing groove 200 is fixed through the fixing blocks on the side of the box body 1. The installation of the plurality of rotating shafts 17 is realized through the placing plate 15 in the blowing groove. At the same time, the debris generated after cutting is blown by the plurality of blades 18 on the plurality of rotating shafts 17 for cleaning to avoid affecting the subsequent accuracy.

[0030] As a further embodiment provided by the present invention, according to Figure 1 and Figure 2 Figure, a filter plate 20 is provided on the placing plate 15. A plurality of shielding holes 16 arranged in a linear array are provided in the filter plate 20.

[0031] Specifically, the shielding holes 16 on the filter plate 20 prevent external dust from being blown onto the backlight plate by the blades 18, thus affecting the accuracy during cutting.

[0032] As a further embodiment provided by the present invention, according to Figure 2 Figure, a guide chute 21 is provided in the side fixing block 14. A cross bar 22 is slidably arranged in the guide chute 21.

[0034] Specifically, the backlight panel is located within the fixed opening 36, squeezing the fixed plate 38. Meanwhile, multiple elastic members 37 are stressed and move inward. They are conveyed through multiple conveying rollers 100. At the same time, the slider 29 on the fixed rod 27 slides downward within the sliding groove 28, and simultaneously presses and fixes the backlight panel to prevent the backlight panel from shaking during cutting. Then, cutting is performed. Through numerical control operation, the cross bar 22 slides within the sliding groove 23, and the cutting member 25 cuts the backlight panel.

[0035] As a further embodiment provided by the present invention, according to Figure 2 As shown, a fixed rod 27 is fixedly provided at the end of the guiding sliding groove 21, and a sliding groove 28 is formed on the fixed rod 27.

[0036] Furthermore, a slider 29 is slidably arranged within the sliding groove 28, and a pressing block 26 is arranged at the bottom of the slider 29.

[0037] Specifically, the debris blown by the fan blade 18 will fall into the third notch 121 formed on the dropping box 12 for collection. Meanwhile, when cleaning is required, the handle 13 is pulled to slide the dropping box 12 out of the third notch 121 for cleaning. After the backlight panel is cut, it will fall into the collection groove 31 within the collection box 30 and simultaneously land on the bearing plate 32. At this time, the bearing plate 32 moves downward, and the sleeve rod 34 slides downward on the vertical rod 35 for buffering, avoiding damage to the backlight panel when it drops. When the backlight panel is detached, multiple elastic members 37 release force. At this time, the fixed plate 38 moves outward and abuts against the limiting plate 39 for limiting.

[0038] As a further embodiment provided by the present invention, according to Figure 2 As shown, a second notch 11 is formed on the box body 1, a dropping box 12 is slidably arranged within the second notch 11, a handle 13 is arranged on the dropping box 12, and a third notch 121 is formed on the dropping box 12.

[0039] Specifically, the debris blown by the fan blade 18 will fall into the third notch 121 formed on the dropping box 12 for collection. Meanwhile, when cleaning is required, the handle 13 is pulled to slide the dropping box 12 out of the third notch 121 for cleaning. After the backlight panel is cut, it will fall into the collection groove 31 within the collection box 30 and simultaneously land on the bearing plate 32. At this time, the bearing plate 32 moves downward, and the sleeve rod 34 slides downward on the vertical rod 35 for buffering, avoiding damage to the backlight panel when it drops. When the backlight panel is detached, multiple elastic members 37 release force. At this time, the fixed plate 38 moves outward and abuts against the limiting plate 39 for limiting.

[0040] As a further embodiment provided by the present invention, according to Figure 2As shown in the figure, a collection box 30 is provided on the box body 1. A collection groove 31 is opened on the collection box 30. A bearing plate 32 is arranged in the collection groove 31. A predetermined gap is left between the bearing plate 32 and the bottom of the collection groove 31 to form a buffer cavity 33.

[0041] Furthermore, a plurality of vertical rods 35 arranged in a linear array are provided in the buffer cavity 33. A plurality of sleeve rods 34 arranged in a linear array are provided at the bottom of the bearing plate 32. The sleeve rods 34 are sleeved on the vertical rods 35, and the sleeve rods 34 and the vertical rods 35 form a hydraulic rod.

[0042] Specifically, after the backlight plate is cut, it will fall into the collection groove 31 in the collection box 30 and at the same time fall on the bearing plate 32. At this time, the bearing plate 32 moves downward, and at the same time the sleeve rod 34 slides downward on the vertical rod 35 for buffering, avoiding damage when the backlight plate falls. When the backlight plate detaches, a plurality of elastic members 37 release force. At this time, the fixing plate 38 moves outward and abuts against the limiting plate 39 for limiting.

[0043] As a further embodiment provided by the present invention, according to Figure 2 As shown in the figure, a fixing port 36 is opened on the side surface of the side fixing block 14. A plurality of elastic members 37 arranged in a linear array are provided in the fixing port 36. A fixing plate 38 is slidably arranged in the fixing port 36. The other end of the elastic member 37 is arranged in the fixing port 36. Limiting plates 39 are symmetrically arranged on the fixing port 36.

[0044] Specifically, when the backlight plate is placed in the fixing port 36, the fixing plate 38 is squeezed, and at the same time a plurality of elastic members 37 are stressed and move inward. When the backlight plate detaches, a plurality of elastic members 37 release force. At this time, the fixing plate 38 moves outward and abuts against the limiting plate 39 for limiting.

[0045] Working principle: First, place the backlight panel on multiple conveying rollers 100 on the box body 1. At this time, the backlight panel is located within the fixed opening 36, squeezing the fixed plate 38. Meanwhile, multiple elastic members 37 are stressed and move inward. The backlight panel is conveyed through the multiple conveying rollers 100. At the same time, the slider 29 on the fixed rod 27 slides downward within the sliding groove 28, pressing and fixing the backlight panel simultaneously to prevent the backlight panel from shaking during cutting. Then, cutting is performed. Through numerical control operation, the cross bar 22 slides within the sliding groove 23, and the cutting member 25 cuts the backlight panel. Meanwhile, the debris generated by cutting is blown away by the rotation of multiple fan blades 18 on multiple rotating shafts 17 within the first notch 19 on the placement plate 15. The debris blown by the fan blades 18 falls into the third notch 121 opened on the dropping box 12 for collection. Meanwhile, when cleaning is required, pull the handle 13 to slide the dropping box 12 out of the third notch 121 for cleaning. After the backlight panel is cut, it falls into the collection groove 31 within the collection box 30 and lands on the bearing plate 32. At this time, the bearing plate 32 moves downward, and the sleeve rod 34 slides downward on the vertical rod 35 for buffering to prevent the backlight panel from being damaged when it drops. When the backlight panel is detached, multiple elastic members 37 release force. At this time, the fixed plate 38 moves outward and abuts against the limiting plate 39 for limiting.
