[0001] The utility model relates to the technical field of brightness enhancement films, in particular to a production device for brightness enhancement films used in liquid crystal displays. Background Art

[0002] Brightness enhancement film, also known as BEF, is an optical film with a uniform prism pattern that is precisely formed using acrylic resin on the surface of PET with very high transparency. It is assembled in front of the backlight source to focus the light emitted by the light source toward the user of the display device, which can increase the front brightness by about 100%. In addition, the unused light outside the viewing angle is recycled based on the light re-reflection effect and focused toward the user at the most appropriate angle.

[0003] After searching, Chinese patent announcement number: CN216836301U discloses a production device for a brightness enhancement film for a liquid crystal display, including a body, a material wheel is arranged on the top of the body, support blocks are arranged on both sides of the bottom of the material wheel, a slot for use with the material wheel is opened on the top of the support block, and a fixed block is movably connected to the top of the support block. The utility model solves the problem that when the existing splitting device splits the brightness enhancement film in the material wheel, the material wheel is easily pulled out of the corresponding slot due to the lack of something to limit the material wheel, thereby affecting the normal operation of the splitting device by setting the body, material wheel, support block, slot, fixed block, T-block, T-slot, limit mechanism, slide bar, sleeve, limit rod, tension spring, adjustment mechanism, adjustment rod, movable block, transmission block, matching block, limit slot, fixed slot, adjustment hole, slider, slide slot and limit hole.

[0004] The lack of the fixing mechanism causes the position of the brightness enhancement film to shift during cutting, thereby damaging the appearance of the brightness enhancement film. Therefore, a production device for a brightness enhancement film for a liquid crystal display is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a production equipment for brightness enhancement film for liquid crystal displays, aiming to improve the problem in the prior art that the brightness enhancement film can be fixed and straightened through a fixing mechanism, provide a more stable working process, and ensure the accuracy and consistency of the brightness enhancement film during the cutting process.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a production equipment of a brightness enhancement film for a liquid crystal display, comprising a cutting table, a motor is fixedly connected to the inner side of the cutting table, a bidirectional threaded rod is rotatably connected to the driving end of the motor, two movable plates are threadedly connected to the outer periphery of the bidirectional threaded rod, the tops of the two movable plates are fixedly connected to a fixing frame, two screws are threadedly connected to one side of the top of the two fixing frames, the tops of the two screws are fixedly connected to a turning handle, the bottoms of the two screws are fixedly connected to a pressing plate, the bottoms of the two pressing plates are fixedly connected to an anti-slip pad, a cutting assembly is arranged at one end of the cutting table, and a placing assembly is arranged at one end of the cutting table.

[0007] Furthermore, the placement assembly includes two fixed seats, one of which is slidably connected to one side of the cutting table, and the other is fixedly connected to one side of the cutting table, one side of one of the fixed seats is slidably connected to a placement rod, and one side of the other fixed seat is fixedly connected to a placement rod, and a fixing assembly is provided on one side of one of the fixed seats.

[0008] Furthermore, the fixing assembly includes an insertion rod, which is slidably connected to one side of the interior of one of the fixing seats, a pull ring is fixedly connected to the front end of the left side of the insertion rod, and a spring is sleeved on the outer periphery of the insertion rod.

[0009] Furthermore, connecting plates are fixedly connected to both sides of the top of the cutting table, and one end of one of the connecting plates is fixedly connected to a motor.

[0010] Furthermore, the driving end of the motor is rotatably connected to a rotating rod, one side of the rotating rod is fixedly connected to one of the cams, and one side of one of the cams is fixedly connected to a connecting rod.

[0011] Furthermore, two slide plates are fixedly connected to the outer periphery of the connecting rod, and the bottom sides of the two slide plates are slidably connected to sliding shafts.

[0012] Furthermore, the bottoms of the two sliding shafts are fixedly connected with a fixing plate.

[0013] Furthermore, a cutter is fixedly connected to the bottom of the fixing plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the brightness enhancement film is inserted into a fixing frame, and the corners of the brightness enhancement film are fixed by a pressure plate on another fixing frame. The handle is turned to drive the screw to rotate on a fixing frame, so that the pressure plate is lowered to fix the corners of the reinforced geotextile. The anti-skid pad can further strengthen the fixation to prevent slipping. At this time, the other side of the brightness enhancement film is fixed by the other fixing frame in the same way as above. At this time, the motor is started, and the motor drives the bidirectional threaded rod to rotate. Subsequently, the thread effect of the bidirectional threaded rod allows the two movable plates to move with the two fixing frames in opposite directions, thereby tightening the brightness enhancement film for cutting. The above method can achieve the brightness enhancement film being fixed and straightened, providing a more stable working process, and ensuring the accuracy and consistency of the brightness enhancement film during the cutting process.

[0016] 2. In the utility model, when replacing the brightness enhancement film, the pull ring is pulled to generate a telescopic force on the spring, driving the insertion rod to move in one direction. At this time, the volume of the spring is larger than the insertion rod, so it will be stuck in the cutting table. Then the insertion rod can be separated from a fixed seat, and a fixed seat can be slid out to reinsert the replaced brightness enhancement film onto the placement rod. Then, a fixed seat is released by loosening the pull ring to allow the spring to exert a telescopic force again to rebound and re-fix the insertion rod. Through the above, it is possible to quickly replace brightness enhancement films of different sizes and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, the brightness enhancement film is inserted into one fixing frame 2, and the corners of the brightness enhancement film are fixed by the pressure plate 7 on the other fixing frame 2. The handle 9 is turned to drive the screw 8 to rotate on one fixing frame 2, so that the pressure plate 7 is lowered to fix the brightness enhancement film. The anti-skid pad 6 can further strengthen the fixation to prevent slipping. At this time, the other side of the brightness enhancement film is fixed by the other fixing frame 2 in the same way as above. At this time, the motor 5 is started, and the motor 5 drives the bidirectional threaded rod 4 to rotate. Then, the thread effect of the bidirectional threaded rod 4 can allow the two movable plates 3 to move with the two fixing frames 2 in opposite directions, thereby tightening the brightness enhancement film for cutting. The motor 17 can drive a rotating rod 18 to rotate for cutting.

[0027] Reference Figure 1 and Figure 4The placement component includes two fixed seats 14, one of which is slidably connected to one side of the cutting table 1, and the other fixed seat 14 is fixedly connected to one side of the cutting table 1. One side of one of the fixed seats 14 is slidably connected with a placement rod 15, and one side of the other fixed seat 14 is fixedly connected with the placement rod 15. A fixing component is arranged on one side of one of the fixed seats 14, and the fixing component includes an insertion rod 12, the insertion rod 12 is slidably connected to one side of the inside of one of the fixed seats 14, a pull ring 10 is fixedly connected to the front end of the left side of the insertion rod 12, a spring 13 is sleeved on the outer periphery of the insertion rod 12, and a rotating rod 18 is rotatably connected to the driving end of the motor 17, one side of the rotating rod 18 is fixedly connected to one of the cams 19, and one side of one of the cams 19 is fixedly connected to a connecting rod 20.

[0028] Specifically, when replacing the brightness enhancement film, the pull ring 10 is pulled to generate a telescopic force on the spring 13, thereby driving the insertion rod 12 to move in one direction. At this time, the volume of the spring 13 is larger than the insertion rod 12, so that it will be stuck in the cutting table 1, and then the insertion rod 12 can be separated from a fixing seat 14, and a fixing seat 14 can be slid out, so that the replaced brightness enhancement film is reinserted onto the placement rod 15, and then a fixing seat 14 is loosened by loosening the pull ring 10 so that the spring 13 exerts a telescopic force again to rebound and re-fix the insertion rod 12, and the motor 17 is started to drive a rotating rod 18 to rotate, and the rotating rotating rod 18 drives a cam 19 to rotate, and then another cam 19 is driven to rotate through the connecting rod 20.

[0029] Reference Figure 1 and Figure 3 Two slide plates 21 are fixedly connected to the outer periphery of the connecting rod 20, and the bottom sides of the two slide plates 21 are slidably connected to sliding shafts 23.

[0030] Specifically, the starting motor 17 drives a rotating rod 18 to rotate, and the rotating rotating rod 18 drives a cam 19 to rotate. At this time, another cam 19 is driven to rotate through the connecting rod 20. At this time, the two rotating cams 19 move the two movable plates 3 through irregular shapes, and the two movable slides 21 slide through the rotation of the sliding shaft 23, so that the fixed plate 24 moves up and down in the two connecting plates 16. At this time, the fixed plate 24 drives the cutter 22 to cut the stretched brightness enhancement film.

[0031] Working principle: insert the brightness enhancement film into one fixing frame 2, and fix the edge of the brightness enhancement film through the pressure plate 7 on the other fixing frame 2, turn the handle 9 to drive the screw 8 to rotate on one fixing frame 2, so as to lower the pressure plate 7 to fix the brightness enhancement film, and the anti-skid pad 6 can further strengthen the fixation to prevent slipping. At this time, fix the other side of the brightness enhancement film on the other fixing frame 2 in the same way as above, and then start the motor 5, which drives the bidirectional threaded rod 4 to rotate. Then, through the thread effect of the bidirectional threaded rod 4, the two movable plates 3 can move with the two fixing frames 2 in opposite directions, thereby tightening the brightness enhancement film for cutting.

[0032] When replacing the brightness enhancement film, pull the pull ring 10 to generate a telescopic force on the spring 13, driving the insertion rod 12 to move in one direction. At this time, the volume of the spring 13 is larger than the insertion rod 12, so it will be stuck in the cutting table 1, and then the insertion rod 12 can be separated from a fixing seat 14, and a fixing seat 14 can be slid out, so that the replaced brightness enhancement film can be reinserted into the placement rod 15, and then a fixing seat 14 can be loosened by loosening the pull ring 10 to allow the spring 13 to exert a telescopic force again to rebound and re-fix the insertion rod 12.
