DETAILED DESCRIPTION

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0029] A cutting device for TFT production, such as Figure 1-Figure 4 As shown, it includes a base 1, a supporting platform 2, a discharge platform 21, a mounting frame 3, a driving mechanism, a scribing mechanism and an extrusion mechanism. The top of the base 1 is connected to the supporting platform 2, the front side of the supporting platform 2 is provided with an inclined discharge platform 21, the front side of the supporting platform 2 is connected to the mounting frame 3, the mounting frame 3 is provided with a driving mechanism, the driving mechanism is provided with a scribing mechanism for scribing the TFT glass 100 and an extrusion mechanism for dividing the scribed TFT glass 100 into blocks.

[0030] like Figure 1-Figure 3 As shown, the driving mechanism includes an electric guide rail 41, a sliding table 42, a cylinder 43 and a lifting block 44. The electric guide rail 41 is installed on the front side of the mounting frame 3, the moving body of the electric guide rail 41 is connected to the sliding table 42, the upper part of the sliding table 42 is installed with a cylinder 43, the telescopic rod of the cylinder 43 is connected to the lifting block 44, the lifting block 44 is slidably connected to the sliding table 42, and the sliding of the lifting block 44 can be guided by the sliding table 42.

[0031] like Figure 1-Figure 3As shown, the scribing mechanism includes a bracket 51, a slider 52, a glass scratcher 53, a guide rod 54, an adjustment component and a glass scratcher 45. The bracket 51 is installed on both the left and right sides of the sliding platform 42. The slider 52 is slidably connected to the bracket 51. The glass scratcher 53 is installed at the bottom of the slider 52. The lower part of the bracket 51 is connected to the guide rod 54. The glass scratcher 53 is slidably connected to the guide rod 54. The glass scratcher 45 is installed on the front side of the lifting block 44. The glass scratcher 45 and the glass scratcher 53 can scratch the TFT glass 100. An adjustment component for adjusting the position of the slider 52 is provided between the slider 52 and the sliding platform 42.

[0032] like Figure 2 As shown, the adjustment component includes a driving motor 551, a driving gear 552 and a rack 553. The driving motor 551 is installed on the top of the slider 52, and the driving gear 552 is connected to the output shaft of the driving motor 551. The rack 553 is installed on the front side of the sliding table 42, and the driving gear 552 is meshed with the rack 553.

[0033] like Figure 4 As shown, the extrusion mechanism includes an extrusion frame 61, a pressure plate 62, a slide bar 63, an elastic member 64 and a pressure block 65. The front side of the lifting block 44 is connected to the extrusion frame 61, and the lower part of the extrusion frame 61 is inclined. The front parts of the left and right sides of the support platform 2 are slidably connected to the slide bars 63, and the slide bars 63 can slide up and down along the support platform 2. An elastic member 64 is connected between the slide bar 63 and the support platform 2, and the elastic member 64 is a return spring. A pressure plate 62 is connected between the two slide bars 63, and the downward movement of the pressure plate 62 can squeeze the TFT glass 100, thereby realizing the preliminary block processing of the TFT glass 100. The left and right sides of the top of the pressure plate 62 are connected to the pressure blocks 65, and the upper part of the pressure blocks 65 is inclined. When the extrusion frame 61 moves to contact the inclined part of the pressure block 65, it can squeeze the pressure block 65 to move downward.

[0034] When it is necessary to cut the TFT glass 100, the device can be used. When in use, the TFT glass 100 is first placed on the supporting platform 2. After placement, the telescopic rod of the control cylinder 43 is extended, thereby driving the lifting block 44 and the glass cutter 1 45 to move downward. When the lifting block 44 moves downward, it can drive the bracket 51 to move downward. When the bracket 51 moves downward, it drives the slider 52 and the glass cutter 2 53 to move downward, so that the bottom of the glass cutter 1 45 and the glass cutter 2 53 are flush with the height of the TFT glass 100, and then it can be pushed. The TFT glass 100 is moved, and vertical scratches can be scraped on the TFT glass 100 by the glass scratcher 1 45 and the glass scratcher 2 53. When the vertical scratches reach a certain depth, the electric guide rail 41 is controlled to drive the sliding table 42 to move, thereby driving the glass scratcher 1 45 and the glass scratcher 2 53 to slide horizontally on the TFT glass 100, scratching horizontal scratches on the TFT glass 100, thereby scratching areas on the TFT glass 100. After scratching, the electric guide rail 41 is continued to be controlled to drive the sliding table 42 to move When the sliding table 42 moves, it drives the extrusion frame 61 to move together through the lifting block 44. When the extrusion frame 61 moves to contact the pressure block 65, the extrusion frame 61 continues to move to press the pressure block 65 to move downward. When the pressure block 65 moves downward, it drives the pressing plate 62 to move downward. The downward movement of the pressing plate 62 drives the sliding rod 63 to move downward. The elastic member 64 is compressed. When the pressing plate 62 moves downward, it can press the front side of the position where the TFT glass 100 is cut, so that the TFT glass 100 is broken along the horizontal scratch. In this way, the TFT glass 100 can be cut. During the cutting work of the FT glass 100, it can be divided into multiple sections first to facilitate the subsequent breaking work. In the actual operation, due to the different sizes of the cracks of the TFT glass 100, it is necessary to adjust the interval of the marked areas. At this time, the driving motor 551 can be controlled to drive the driving gear 552 to rotate, so that the driving gear 552 moves along the rack 553 to drive the slider 52 and the glass cutter 53 to move together, thereby adjusting the positions of the slider 52 and the glass cutter 53, and then adjusting the interval between the marked areas.

[0035] like Figure 5 As shown, a feeding mechanism is also included, which includes a connecting frame 71, a reduction motor 72, a driving screw 73 and a pushing frame 74. Two connecting frames 71 are connected to the rear side of the support platform 2, and reduction motors 72 are installed on the upper parts of the two connecting frames 71. The output shaft of the reduction motor 72 is connected to the driving screw 73, and the driving screw 73 is rotatably connected to the mounting frame 3. A pushing frame 74 is threadedly connected between the two driving screws 73, and the bottom of the pushing frame 74 is flush with the top of the support platform 2. The TFT glass 100 is placed on the top of the support platform 2, and the pushing frame 74 can push the TFT glass 100 to move when it moves.

[0036] When it is necessary to push the TFT glass 100 to move, the reduction motor 72 can be controlled to drive the driving screw 73 to rotate. When the driving screw 73 rotates, it can drive the pushing rack 74 to move to the left through the thread. When the pushing rack 74 moves to the left, it can contact the TFT glass 100 and push the TFT glass 100 to move to the left, thereby achieving the effect of conveying the TFT glass 100, which is more convenient during transportation.

[0037] like Figure 6 and Figure 7 As shown, it also includes a clamping mechanism, which includes a dual-axis motor 81, an adjusting screw 82 and a clamping frame 83. The dual-axis motor 81 is installed in the support platform 2, and the two output shafts of the dual-axis motor 81 are connected to the adjusting screws 82. The left and right sides of the support platform 2 are slidably connected with the clamping frames 83, and the clamping frames 83 are threadedly matched with the adjusting screw 82 so that the rotation of the adjusting screw 82 can drive the clamping frame 83 to move through the thread.

[0038] After the TFT glass 100 is placed, the dual-axis motor 81 can be controlled to drive the adjusting screws 82 on both sides to rotate. When the adjusting screws 82 rotate, they can drive the clamping frames 83 on both sides to approach each other and align the left and right sides of the TFT glass 100 through the threads, thereby limiting the left and right positions of the TFT glass 100 to avoid the position of the TFT glass 100 from being offset when the TFT glass 100 is transported.

[0039] like Figure 8 and Fig. 9 As shown, an air suction mechanism is also included, which includes an air guide frame 91, an air suction nozzle 92, a dust collecting frame 93 and an air suction pump 94. The front side of the top of the support platform 2 is connected to the air guide frame 91, and a plurality of air suction nozzles 92 are evenly spaced on the front side of the air guide frame 91. The top of the air guide frame 91 is connected to the dust collecting frame 93, and the top of the dust collecting frame 93 is equipped with an air suction pump 94.

[0040] When glass cutter 1 45 and glass cutter 2 53 move on TFT glass 100 for cutting, some debris will be scratched on the glass surface. At this time, the suction pump 94 can be controlled to start, and the debris generated in the cutting process can be sucked into the dust collection frame 93 through the suction nozzle 92, which effectively avoids the debris from scattering everywhere, keeps the working environment clean, and reduces the interference or damage that the debris may cause to subsequent processes.

[0041] like Fig.10As shown, it also includes a cloth pad 101 and a cloth pad 102. The top of the support platform 2 is connected to the cloth pad 102, and the top of the unloading platform 21 is connected to the cloth pad 101. Through the use of the cloth pad 101 and the cloth pad 102, the TFT glass 100 can be effectively protected to prevent the surface of the TFT glass 100 from being scratched due to tiny hard objects or uneven areas on the platform surface when it is placed on the support platform 2. The soft material of the cloth pad can act as a buffer layer to ensure the safety of the TFT glass 100 on the support platform 2 and prevent any possible damage, thereby protecting the integrity of the glass and its optical properties.
