Description

Polarizing film clamping device Technical Field

[0001] This application relates to the technical field of polarizer processing equipment, and in particular to a polarizer clamping device. Background Technology

[0002] The full name of a polarizer is polarizing film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizing films, one in front and one behind, which are closely attached to the liquid crystal glass to form a liquid crystal film with a total thickness of about 1mm.

[0003] Currently, a clamping device with announcement number CN206578848U includes a clamping mechanism and a receiving box capable of accommodating a workpiece. The receiving box includes a box body having two openings arranged opposite to each other and capable of being separated, and a base plate detachably connected to the box body at one of the openings. The clamping mechanism includes a clamping member capable of pressing the workpiece at the other opening.

[0004] Regarding the aforementioned technologies, after the polarizers are stacked and clamped, their sides need to be cut. During the cutting process, the housing is removed. Because the polarizers have a layered structure with adhesive material between the layers, and each polarizer is thin and has a smooth surface, they are prone to lateral slippage during the cutting process. Summary of the Invention

[0005] To reduce the possibility of lateral slippage of the polarizer during the cutting process, this application provides a polarizer clamping device.

[0006] The polarizer clamping device provided in this application adopts the following technical solution:

[0007] A polarizer clamping device, comprising:

[0008] Control panel;

[0009] A clamping assembly is installed on the operating table. The clamping assembly includes a receiving platform and a clamping member. The receiving platform is fixedly connected to the operating table and is used to receive a polarizer. The clamping member is located above the receiving platform and is used to clamp the polarizer on the receiving platform.

[0010] A positioning assembly is slidably connected to the operating table. The positioning assembly includes two positioning plates. The clamping assembly is located between the two positioning plates. The positioning plates are bent at 90 degrees and are used to abut against the right angle of the polarizer.

[0011] A cutting assembly is mounted on the operating table, and the cutting assembly is used to cut the polarizer on the clamping assembly;

[0012] An abutment assembly is installed on the operating table. The abutment assembly includes two abutment plates, and the receiving platform is located between the two abutment plates. The abutment plates are used to abut against the side of the polarizer.

[0013] By adopting the above technical solution, the sliced ​​polarizers are stacked on the receiving platform of the clamping assembly. Then, the positioning plate on the driving positioning assembly moves, and the right-angled part of the positioning plate abuts against the right-angled part of the stacked polarizers, thereby completing the precise positioning of the stacked polarizers. Next, the clamping member moves downward to press the stacked polarizers together, and then the positioning plate resets. Then, the cutting assembly cuts the stacked polarizers. During the cutting process, the abutment plate of the abutment assembly abuts against both sides of the polarizers, thereby reducing the possibility of lateral slippage of the polarizers during the cutting process.

[0014] Optionally, a threaded rod is fixedly connected to the operating table, a fixed plate is threadedly connected to the threaded rod, a rotating table is rotatably connected to the fixed plate, and the cutting assembly is fixedly connected to the rotating table.

[0015] By adopting the above technical solution, the cooperation between the threaded rod and the fixed plate facilitates the up and down movement of the fixed plate. At the same time, the rotating table on the fixed plate allows the cutting assembly to rotate at a certain angle to cut each edge of the polarizer.

[0016] Optionally, the cutting assembly includes a cutting head and a guide screw. The guide screw is rotatably connected to the rotating table and is horizontally arranged along its length. The cutting head is threadedly connected to the guide screw and is vertically arranged.

[0017] By adopting the above technical solution, the cutting head can move horizontally by cooperating with the guide screw, thereby cutting the polarizer.

[0018] Optionally, a polishing assembly is fixedly connected to the rotating platform, and the polishing assembly is used to polish the polarizer.

[0019] By adopting the above technical solution, after the cutting component cuts the polarizer, it needs to be polished. The polishing component is set on the rotating table so that the cutting component can polish the polarizer after cutting it.

[0020] Optionally, the grinding assembly includes a grinding head and a guide screw, the guide screw being rotatably connected to the rotating table, the axis of the guide screw being parallel to the axis of the guide screw and located on the same horizontal plane, the grinding head being threadedly connected to the guide screw, and the receiving platform being located between the grinding head and the cutting head.

[0021] By adopting the above technical solution, the grinding head is guided by the guide screw, which facilitates the movement of the grinding head on the horizontal plane, thereby grinding the cut polarizer.

[0022] Optionally, the abutment assembly is fixedly connected to the rotating platform, the bottom of the rotating platform is a telescopic cylinder, and the abutment plate is fixedly connected to the piston rod of the telescopic cylinder. The length of one abutment plate is greater than the length of the other abutment plate, and the cutting head can abut against the longer abutment plate.

[0023] By adopting the above technical solution, a telescopic cylinder is used to drive the movement of the contact plate, thereby bringing the polarizer into contact. At the same time, the cutting head contacts the contact plate, making it easier for the cutting head to cut the polarizer.

[0024] Optionally, the clamping component includes a clamping head, a clamping rod is connected between the clamping head and the fixed plate, a counterweight is snapped onto the clamping head, and the clamping rod is a telescopic rod.

[0025] By adopting the above technical solution, since the polarizer has a layered structure with adhesive material between the layers, and each polarizer is thin and has a smooth surface, when a stack of polarizers is stacked and pressed for processing, if the pressing pressure is too low, it is impossible to cut the sides; if the pressing pressure is too high, the pressed polarizers are prone to slippage or even collapse from the middle. Therefore, using a counterweight to precisely adjust the pressure of the pressing head on the polarizers facilitates the processing of the polarizers by the cutting assembly.

[0026] Optionally, the positioning component includes a rack and a drive gear. The racks are fixedly connected to the positioning plate in a one-to-one correspondence. The two racks are located on both sides of the drive gear, and the racks mesh with the drive gear.

[0027] By adopting the above technical solution, the two racks are driven to move synchronously by the drive gear, which makes it easier for the positioning plate to center the polarizer.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By cooperating with clamping components, receiving platform, pressing platform, positioning components, positioning plate, cutting components, abutting components and abutting plate, the polarizer is positioned on the receiving platform and clamped. When the cutting component cuts the polarizer, the abutting component abuts against both sides of the polarizer, thereby reducing the possibility of lateral sliding of the polarizer during the cutting process.

[0030] 2. By cooperating with the cutting assembly, threaded rod, fixed plate, and rotating table, the cutting assembly can rotate, thereby achieving the effect of cutting the polarizer from all directions;

[0031] 3. By setting the cutting component, the contact component, and the grinding component all on the rotating table, it is convenient to cut and grind the polarizer simultaneously, thereby improving the processing efficiency. Attached Figure Description

[0037] The present application will be further described in detail below with reference to Figures 1-3.

[0038] This application discloses a polarizer clamping device.

[0039] Referring to Figure 1, the polarizer clamping device includes an operating table 1, on which a clamping assembly 2 is mounted, and positioning assemblies 3 are mounted on both sides of the clamping assembly 2. The positioning assemblies 3 are used to position the stacked polarizers 4 onto the clamping assembly 2, which then clamps them. A cutting assembly 5 and an abutment assembly 6 are also fixedly connected to the operating table 1. The abutment assembly 6 is perpendicular to the cutting assembly 5. When the cutting assembly 5 cuts one side of the polarizer 4, the abutment assembly 6 abuts against the two adjacent sides of the polarizer 4 being cut, thereby reducing the possibility of lateral sliding of the polarizer 4 during the cutting process.

[0040] Referring to Figure 1, two threaded rods 11 and two guide rods 12 are fixedly connected to the operating table 1. All two threaded rods 11 and two guide rods 12 are vertically arranged and evenly distributed around the clamping assembly 2. The two threaded rods 11 are located on opposite sides of the clamping assembly 2. A fixing plate 13 is threadedly connected to each threaded rod 11. The fixing plate 13 is slidably connected to the guide rod 12. A transmission gear 14 is rotatably connected to the fixing plate 13, and the transmission gear 14 is threadedly connected to each threaded rod 11 in a corresponding manner. A transmission belt 15 is fitted onto each of the two transmission gears 14, enabling the two transmission gears 14 to rotate synchronously, thereby driving the fixing plate 13 to slide vertically.

[0041] Referring to Figure 2, a rotating platform 7 is rotatably connected to the bottom of the fixed plate 13. The edge of the rotating platform 7 is provided with gear teeth. A rotating motor 16 is fixedly connected to the fixed plate 13, and the output shaft of the rotating motor 16 meshes with the gear teeth of the rotating platform 7. The rotating platform 7 is driven to rotate by the rotating motor 16. At the same time, the rotating motor 16 has a self-locking function, which allows the rotating platform 7 to be locked when the cutting assembly 5 is working.

[0042] Referring to Figures 1 and 2, a grinding assembly 8 is fixedly connected to the bottom of the rotating table 7, while a cutting assembly 5 and abutment assembly 6 are also fixedly connected to the bottom of the rotating table 7. The grinding assembly 8 and the cutting assembly 5 are located on both sides of the clamping assembly 2, and the abutment assembly 6 includes two abutment plates 61, which are located on both sides of the clamping assembly 2, so that the cutting assembly 5, the abutment assembly 6, and the two abutment plates 61 are evenly distributed around the clamping assembly 2.

[0043] By mounting the cutting assembly 5 and the abutment assembly 6 on the rotating table 7, the abutment assembly 6 can abut against both sides of the polarizer 4 when the cutting assembly 5 is cutting in all directions, making it less likely for the polarizer 4 to slip. At the same time, the grinding assembly 8 is also mounted on the rotating table 7, which facilitates grinding of the polarizer 4 after the cutting assembly 5 has cut it, thus improving work efficiency.

[0044] Referring to Figure 2, four support frames 71 are fixedly connected to the bottom of the rotating table 7. Each support frame 71 is connected to a telescopic cylinder 72 at its bottom. Two of the telescopic cylinders 72 are fixedly connected to guide shells 73, and the piston rods of the other two telescopic cylinders 72 are fixedly connected to the abutment plate 61.

[0045] Referring to Figure 2, the cutting assembly 5 includes a cutting head 51 and a guide screw 52. The guide screw 52 is rotatably connected to the guide housing 73 and is horizontally arranged. The cutting head 51 is threadedly connected to the guide screw 52 and is vertically arranged. The cutting blade on the cutting head 51 is inclined, and the inclined cutting blade facilitates the cutting of the polarizer 4.

[0046] Referring to Figure 2, the length of the abutment plate 61 closer to the inclined direction of the cutting blade is greater than the length of the abutment plate 61 on the other side, so that the cutting blade can abut against the abutment plate 61 when cutting the polarizer 4, thereby facilitating the cutting head 51 to cut the polarizer 4.

[0047] Referring to Figure 1, the polishing assembly 8 includes a polishing head 81 and a guide screw 82. The guide screw 82 is rotatably connected within another guide housing 73, and its axis is horizontally positioned and parallel to the axis of the guide screw 52. The polishing head 81 is threaded onto the guide screw 82, and the polishing head 81 can polish the polarizer 4 through the guidance of the guide screw 82.

[0048] During the processing of the polarizer 4, the abutment plate 61 abuts against both sides of the polarizer 4, reducing the possibility of slippage and improving product quality. Simultaneously, after cutting the polarizer 4, the grinding assembly 8 is used to grind the polarizer 4, improving the production efficiency of the polarizer 4.

[0049] Referring to Figure 1, the clamping assembly 2 includes a receiving platform 21 and a clamping member 22. The receiving platform 21 is fixedly connected to the operating table 1, and the clamping member 22 is located directly above the receiving platform 21. The clamping member 22 includes a clamping head 221, and a clamping rod 23 is connected between the clamping head 221 and the rotating table 7. The clamping rod 23 is vertically arranged and is a freely telescopic rod. A counterweight 222 is engaged on the clamping head 221. The counterweight 222 is used to precisely adjust the pressure exerted by the clamping head 221 on the stacked polarizers 4, thereby ensuring that the pressure exerted by the clamping head 221 on the polarizers 4 remains stable and is not affected by the movement of the fixing plate 13.

[0050] Referring to Figures 1 and 3, the positioning assembly 3 includes two positioning plates 31 located on the diagonal line connecting the polarizer 4. The positioning plates 31 are bent at 90 degrees, allowing them to abut against the diagonal points of the polarizer 4. A rack 32 is fixedly connected to the bottom of each positioning plate 31, and a drive gear 33 is positioned between the two racks 32, meshing with the racks 32. The rotation of the drive gear 33 simultaneously moves the two racks 32, enabling the positioning plates 31 to move synchronously and precisely center the polarizer 4, resulting in more accurate positioning of the polarizer 4.

[0051] The implementation principle of the polarizer pressing device in this application embodiment is as follows: the stacked polarizers 4 are placed on the receiving platform 21, and then the drive gear 33 is driven to rotate, so that the positioning plate 31 positions the stacked polarizers 4. After positioning, the drive gear 14 is driven to rotate, and the drive gear 14 rotates synchronously through the drive belt 15, so that the fixing plate 13 moves downward, so that the pressing head 221 abuts against the upper surface of the polarizer 4. Since a suitable counterweight 222 is installed on the pressing head 221, the polarizer 4 is stably pressed.

[0052] Next, the positioning plate 31 is reset, and the fixing plate 13 continues to move downward, so that the polarizer 4, cutting assembly 5, abutment assembly 6, and grinding assembly 8 are on the same horizontal plane. Then, the high-precision telescopic cylinder 72 is driven to abut the abutment plate 61 against the polarizer 4, and the cutting head 51 approaches the polarizer 4. Then, the guide screw 52 is driven to rotate, and the rotation of the guide screw 52 causes the cutting head 51 to perform fine finishing on the polarizer 4. After the fine finishing on one side of the polarizer 4 is completed.

[0053] Next, the telescopic cylinder 72 is reset, and the rotating motor 16 drives the rotating table 7 to rotate 90 degrees, thereby rotating the cutting component 5, the abutment component 6, and the grinding component 8 by 90 degrees simultaneously to process the polarizer 4 on the other side. At the same time, the grinding component 8 can grind the polarizer 4 after cutting, which improves work efficiency.

[0054] By utilizing the cooperation of the rotating table 7, the cutting assembly 5, and the abutting assembly 6, the abutting assembly 6 is always abutted against the side wall of the polarizer 4, regardless of which direction the cutting assembly 5 processes the polarizer 4, thereby reducing the possibility of the polarizer 4 sliding laterally during the cutting process.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
