[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizing films in front and back tightly attached to the liquid crystal glass to form a liquid crystal film.

[0003] In the related art, in order to improve the grinding and cutting efficiency, multiple polarizers are generally stacked manually and placed on the workbench of the edge grinding machine. The edge grinding machine is provided with a cylinder for pressing the stacked polarizers; however, manually stacking multiple polarizers on the workbench of the edge grinding machine can easily cause the position of the polarizers to deviate, which in turn can easily affect the edge grinding accuracy and efficiency of the edge grinding machine. Summary of the Invention

[0004] In order to improve the problem that the position of manually aligned polarizers is easily deviated during edging, thereby affecting the edging accuracy and efficiency, the present application provides an edging machine for special-shaped polarizers.

[0005] The present application provides a special-shaped polarizer edge grinding machine that adopts the following technical solutions:

[0006] A special-shaped polarizer edge grinding machine includes an edge grinding machine body, a movable platform and an edge grinding platform. The movable platform is provided with a rotating assembly for driving the edge grinding platform to rotate. The edge grinding platform is provided with an alignment assembly for aligning the polarizer group and a pressing assembly for pressing the polarizer group. The edge grinding machine body is provided with an edge grinding assembly for edging the polarizer group. The movable platform moves toward the edge grinding assembly through a displacement assembly.

[0007] By adopting the above technical solution, during processing, personnel place the stacked polarizers on the edge grinding table, and use the alignment component to align the polarizer group on the edge grinding table, and then press the polarizer group by the pressing component; then use the displacement component to drive the movable table to move in the grinding direction, thereby driving the polarizer group on the edge grinding table to move toward the edge grinding component, and then as the polarizer group moves, the edge grinding of the polarizer group by the edge grinding component is realized; the edge grinding machine constructed with the above structure can replace manual alignment of the polarizer group, save time and labor, and help avoid the position deviation of the manually aligned polarizer group, which affects the grinding accuracy and efficiency of the edge grinding machine.

[0008] In a specific embodiment, the alignment assembly includes a plurality of alignment seats arranged on the side wall of the movable platform, the plurality of alignment seats being arranged in an array along the circumference of the grinding and cutting platform, the alignment seats being provided with alignment plates on the side wall facing the grinding and cutting platform, and the side wall of the alignment seats being provided with distance adjusting members for driving the alignment plates to move closer to or away from the alignment seats;

[0009] The opposite side walls of the two opposite alignment seats are each provided with a horizontal cylinder, the piston rod of the horizontal cylinder is connected to a pneumatic clamp, the pneumatic clamp clamps a binding rope for being sleeved on the polarizer group, the binding rope has two free ends, the alignment seat is provided with a tightening part for pulling the two free ends of the binding rope close to each other, and the movable platform is provided with a lifting part for driving the alignment seat to rise and fall.

[0010] By adopting the above technical solution, after stacking the polaroid set on the edging table, the personnel first use the distance adjusting member on the alignment seat to drive the alignment plate to move toward the polaroid set. At this time, several alignment plates are close to each other to align the polaroid set. Then, the aligned polaroid set is compressed by the pressing assembly. Then, the horizontal cylinder is activated, which drives the pneumatic clamp to move above the polaroid set. Then, the pneumatic clamp grips the binding rope and moves it above the polaroid set. The clamping jaws of the pneumatic clamp are released, allowing the binding rope to fall on the top surface of the polaroid set.

[0011] Finally, the tightening part is used to pull the free ends of the two binding ropes closer to each other, and the polarizer group is tied with the binding ropes. Finally, the lifting part is used to drive the alignment seat to move downward, so as to avoid affecting the grinding and cutting of the side wall of the polarizer group by the edging assembly as much as possible; adopting the above scheme, by pressing the polarizer group and bundling the polarizer group with the binding ropes at the same time, it is helpful to avoid the vibration and displacement of the polarizer group during the grinding and cutting process, which helps to improve the grinding and cutting accuracy of the polarizer group.

[0012] In a specific possible implementation scheme, the distance adjusting member includes a first electric cylinder, which is arranged on a side wall of the alignment seat, and a piston rod of the first electric cylinder is connected to the alignment plate.

[0013] By adopting the above technical solution, the piston rod of the first electric cylinder is extended and retracted, so that the alignment plate moves closer to or away from the polarizer group, and then the polarizer group is automatically aligned through the two alignment plates.

[0015] The side wall of the alignment seat is provided with a reduction motor, and the piston rod of the reduction motor is coaxially connected with a bidirectional screw rod.

Both ends of the bidirectional screw rod are threadedly connected with adjustment blocks, and the two adjustment blocks slide in the adjustment groove. The two second electric cylinders correspond one-to-one to the two adjustment blocks respectively, and the second electric cylinders are arranged on the side walls of the adjustment blocks.

[0016] By adopting the above technical solution, when the first electric cylinder drives the pneumatic clamping claw to move toward the polarizer group, the second electric cylinder is started to drive the pneumatic clamping finger to move toward the polarizer group, so as to move the free end of the binding rope to the bottom of the polarizer group; then the reduction motor is started, and the reduction motor drives the bidirectional lead screw to rotate. Since the adjustment groove guides and limits the sliding of the adjustment block, as the bidirectional lead screw rotates, the two adjustment blocks approach or move away from each other in the adjustment groove; when the two adjustment blocks are driven away from each other, the two free ends of the binding belt are driven away from each other by the two second electric cylinders and the two pneumatic clamping fingers, thereby realizing the bundling of the aligned polarizer group, which helps to avoid the misalignment of the polarizer group during grinding and cutting, thereby affecting the grinding and cutting accuracy and efficiency.

[0017] In a specific possible implementation scheme, the lifting member includes a vertical electric cylinder, which is arranged on the side wall of the moving platform, and the piston rod of the vertical electric cylinder is connected to the bottom wall of the alignment seat.

[0018] By adopting the above technical solution, after the polarizer group is bundled with the binding belt, the vertical electric cylinder is started to move downward, which helps to prevent the alignment seat from affecting the grinding and cutting of the polarizer group by the edging assembly.

[0019] In a specific embodiment, the movable platform is provided with a rotating assembly for driving the grinding and cutting platform to rotate. The rotating assembly includes a rotating motor embedded in the top wall of the movable platform. The driving shaft of the rotating motor is connected to the edge grinding platform.

[0020] By adopting the above technical solution, the rotary motor is started, which drives the edge grinding table to rotate, thereby driving the aligned polarizer group to rotate, so that the edge grinding assembly can grind and cut multiple side walls of the polarizer group with high grinding efficiency.

[0021] In a specific possible implementation scheme, the pressing assembly includes a vertical cylinder and a pressing plate. The vertical cylinder is set on a movable table. The piston rod of the vertical cylinder is connected to the pressing plate. The pressing plate is used to press the polarizer group on the edge grinding table.

[0022] By adopting the above technical solution, after the polarizer group on the grinding and cutting table is aligned, the vertical cylinder is started, and the vertical cylinder drives the pressing plate to move downward, and then the aligned polarizer group is pressed on the edge grinding table through the pressing plate.

[0023] In a specific possible implementation scheme, the displacement assembly includes a base, which is used to be set on the ground, and two opposite guide rails are provided on the base. The bottom wall of the mobile platform is rotatably provided with two opposite linkage rods, and the linkage rods are provided with two opposite rollers. The mobile platform is provided with a driving motor for driving the linkage rods to rotate, and the peripheral wall of the roller is provided with an annular groove that cooperates with the guide rail.

[0024] By adopting the above technical solution, the driving motor is started, and the driving motor drives the linkage rod to rotate, and then the rollers at both ends of the linkage rod rotate, and then the rollers are driven to roll on the guide rails, so that the moving seat is moved closer to or away from the edge grinding assembly, so that the edge grinding assembly can grind and cut the side walls of the aligned polarizer group.

[0025] In a specific embodiment, the edge grinding assembly includes two grinding knives, which are arranged opposite to each other on the edge grinding machine body, and the edge grinding machine body is provided with a power motor for driving the grinding knives to rotate.

[0026] By adopting the above technical solution, the movable platform drives the polarizer group to rotate in the grinding direction, and at the same time, the power motor is started, and the power motor drives the grinding knife to rotate, thereby realizing the grinding knife to grind and cut the side wall of the polarizer group. In addition, the two grinding knives are provided so that the side walls of the polarizer group on both sides can be ground and cut at the same time, and the grinding efficiency is high.

[0027] In a specific implementation scheme, two opposing adjusting cylinders are provided on the edge grinding machine body, the two adjusting cylinders correspond to two power motors respectively, the piston rods of the adjusting cylinders are connected to the power motors, and the central axes of the two adjusting cylinders are collinear.

[0028] By adopting the above technical solution, the regulating cylinder is used to drive the power motor to move so as to adjust the distance between the two grinding knives, so as to grind and cut polarizer groups of different sizes and specifications, and the application range is wide.

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The embodiment of the present application discloses a special-shaped polarizer edge grinding machine.

[0044] During grinding and cutting, personnel place the stacked polarizer groups on the grinding and cutting table and align the stacked polarizer groups through the alignment component 5 to replace manual alignment, saving time and effort, and helping to avoid position deviation of manually aligned polarizer groups, thereby improving the grinding and cutting accuracy and efficiency of the polarizer groups.

[0045] After the polarizer group is aligned, the clamping component 9 is used to press the aligned polarizer group onto the grinding and cutting table. At this time, the displacement component 10 can drive the movable table 2 to move toward the edge grinding component 11 so that the polarizer group can be ground and cut by the edge grinding component 11; and the rotating component 4 is used to drive the grinding and cutting table to rotate so that each side wall of the polarizer group can be ground and cut, thereby improving the grinding and cutting efficiency.

[0046] Reference Figure 2 and Figure 3 In this embodiment, there are four groups of alignment components 5, which are respectively arranged on the four side walls of the edging table 3. One group of alignment components 5 includes: an alignment seat 51 and an alignment plate 52. The alignment seat 51 is arranged on the movable table 2 and is located on one side of the grinding and cutting table. The top wall of the movable table 2 is provided with a lifting member 8 for driving the alignment seat 51 to move up and down, and the alignment plate 52 is arranged on the side wall of the alignment seat 51 facing the grinding and cutting table. The side wall of the alignment seat 51 is provided with a distance-adjusting member 6 for driving the alignment plate 52 to move close to or away from the alignment seat 51; when the personnel place the stacked polaroid group on the grinding and cutting table, the lifting member 8 is used to drive the alignment seat 51 to move up so as to align the alignment plate 52 with the polaroid group, and then the distance-adjusting member 6 is used to drive the alignment plate 52 close to the alignment seat 51, so that the alignment plates 52 in the two groups of alignment components 5 are close to each other to achieve alignment of the stacked polaroid group.

[0047] The lifting member 8 includes a vertical electric cylinder 81, the cylinder body of which is set on the top wall of the movable platform 2, and the piston rod of the vertical electric cylinder 81 is connected to the bottom wall of the alignment seat 51; when the vertical electric cylinder 81 is started, the piston rod of the vertical electric cylinder 81 is connected to the bottom wall of the alignment seat 51, thereby realizing the height adjustment of the alignment seat 51 so that personnel can take and place the stacked polarizer groups.

[0048] The distance adjusting member 6 includes a first electric cylinder 61. The cylinder body of the first electric cylinder 61 is horizontally arranged on the side wall of the alignment seat 51. The piston rod of the first electric cylinder 61 is connected to the alignment plate 52. The first electric cylinder 61 is activated to drive the alignment plate 52 to move closer to or away from the alignment seat 51, thereby aligning the polarizer group stacked on the edging table 3.

[0049] Reference Figure 3 and Figure 4Since the polaroid group may vibrate and become brittle when edging the polaroid group, in order to further improve the grinding and cutting accuracy of the polaroid group, a horizontal cylinder 53 is provided on the side walls of the two opposite alignment seats 51, and the cylinder body of the horizontal cylinder 53 is set on the side wall of the alignment seat 51 facing the edging table 3. The piston rod of the horizontal cylinder 53 is fixedly installed with a pneumatic clamp 54, and the pneumatic clamp 54 clamps a binding rope 55 for being sleeved on the polaroid group. The binding rope 55 has two free ends, and the two free ends of the binding rope 55 are staggered with each other. The alignment seat 51 is provided with a tightening member 7 for pulling the two free ends of the binding rope 55 close to each other.

[0050] After the polaroid group is aligned, the first electric cylinder 61 is used to drive the alignment plate 52 away from the polaroid group, and then the horizontal cylinder 53 is started. The piston rod of the horizontal cylinder 53 is extended, so that the pneumatic clamp 54 drives the binding rope 55 to move toward the polaroid group until the binding rope 55 moves to the top of the polaroid group. At this time, the two free ends of the binding rope 55 move to the bottom of the polaroid group, and the two free ends of the binding rope 55 are staggered with each other. Then, the two free ends of the binding rope 55 are tightened by the tightening member 7, thereby realizing the binding of the polaroid group with the binding rope 55. When the polaroid group is edged, it helps to prevent the polaroid group from deviating, thereby improving the grinding and cutting accuracy and efficiency.

[0051] Reference Figure 3 、 Figure 4 and Figure 5 In this embodiment, there are two groups of tightening members 7, and the two groups of tightening members 7 correspond one-to-one to the two alignment seats 51 respectively. One group of tightening members 7 includes two second electric cylinders 71 and two pneumatic clamping fingers 72. The two second electric cylinders 71 are relatively arranged on the side walls of the alignment seat 51. The two second electric cylinders 71 correspond one-to-one to the two free ends of the binding rope 55 respectively. The two pneumatic clamping fingers 72 correspond one-to-one to the two second electric cylinders 71 respectively. The cylinder body of the pneumatic clamping fingers 72 is fixedly installed on the piston rod of the second electric cylinder 71, and the two pneumatic clamping fingers 72 clamp the two free ends of the binding rope 55 respectively.

[0052] The side wall of the alignment seat 51 is provided with a sliding member for adjusting the distance between the two second electric cylinders 71. The sliding member includes a reduction motor 73, a bidirectional screw rod 74 and two adjustment blocks 76. The body of the reduction motor 73 is fixed to the side wall of the alignment seat 51. The side wall of the alignment seat 51 facing the grinding and cutting table is provided with an adjustment groove 75. Both ends of the bidirectional screw rod 74 are rotatably connected to the groove walls on both sides of the adjustment groove 75. The driving shaft of the reduction motor 73 extends into the adjustment groove 75 and is coaxially fixedly connected to one end of the bidirectional screw rod 74. The two adjustment blocks 76 are both slidably set in the adjustment groove 75, and the two adjustment blocks 76 are respectively threadedly connected to the two ends of the bidirectional screw rod 74, and the threads at both ends of the bidirectional screw rod 74 have opposite rotation directions.

[0053] In this embodiment, the two adjustment blocks 76 correspond to the two second electric cylinders 71 respectively, and the cylinder body of the second electric cylinder 71 is fixedly mounted on the side wall of the adjustment block 76; then, when the reduction motor 73 is started, the reduction motor 73 drives the bidirectional screw rod 74 to rotate, and the adjustment slot 75 restricts the sliding of the adjustment block 76. As the bidirectional screw rod 74 rotates, the two adjustment blocks 76 approach or move away from each other. When the two adjustment blocks 76 move away from each other, the two second electric cylinders 71 move away from each other, thereby causing the two free ends of the binding rope 55 to move away from each other. Since the two free ends of the binding rope 55 are in an interlaced state, when the two free ends of the binding rope 55 are pulled away from each other, the binding rope 55 gradually tightens the polarizer group, thereby achieving the binding of the polarizer group.

[0054] Reference Figure 2 The rotating assembly 4 includes a rotating motor 401, which is embedded in the top wall of the movable platform 2, and the driving shaft of the rotating motor 401 is connected to the bottom wall of the edge grinding platform 3; the rotating motor 401 is started to rotate and drive the edge grinding platform 3 to rotate, so as to grind each side wall of the polarizer group in turn, and has a wide range of uses.

[0055] Reference Figure 1 and Figure 6 The pressing assembly 9 includes a vertical cylinder 91 and a pressing plate 92. The cylinder body of the vertical cylinder 91 is fixedly set on the movable platform 2. The piston rod of the vertical cylinder 91 is connected to the pressing plate 92. The pressing plate 92 is set horizontally, and the pressing plate 92 is arranged opposite to the edge grinding platform 3 up and down. After the polarizer group is aligned and bundled, the vertical cylinder 91 is started, the piston rod of the vertical cylinder 91 is extended, and then the pressing plate 92 moves down and presses the aligned polarizer group on the edge grinding platform 3.

[0056] Reference Figure 7 and Figure 8 The displacement assembly 10 includes a base 101, which is used to be fixedly installed on the ground. Two guide rails 102 are relatively provided on the base 101. Two opposite linkage rods 103 are rotatably provided on the bottom wall of the movable platform 2. A driving motor 105 is installed on the bottom wall of the movable platform 2. The driving shaft of the driving motor 105 is coaxially fixedly connected with the linkage rod 103. Two opposite rollers 104 are rotatably provided on the linkage rod 103. The two rollers 104 correspond to the two guide rails 102 one by one, and the peripheral walls of the rollers 104 are provided with an annular groove 106 that matches the guide rails 102. Start the driving motor 105, the driving motor 105 drives the linkage rod 103 to rotate, and then the linkage rod 103 drives the two rollers 104 to rotate synchronously. The rollers 104 roll on the guide rails 102 to drive the movable platform 2 to approach or move away from the edge grinding machine body 1.

[0057] Reference Figure 1 and Figure 2The edge grinding assembly 11 includes two grinding knives 111, which are arranged opposite to each other on the edge grinding machine body 1. The edge grinding machine body 1 is provided with a power motor 112 for driving the grinding knives 111 to rotate; the power motor 112 is started, and the power motor 112 drives the grinding knives 111 to rotate, and then the side wall of the polarizer group is polished by the grinding knives 111.

[0058] In this embodiment, two opposing adjusting cylinders 12 are provided on the side wall of the edge grinding machine body 1, and the two adjusting cylinders 12 correspond to the two power motors 112 one by one. The piston rods of the adjusting cylinders 12 are connected to the body of the power motor 112. The two adjusting cylinders 12 are both horizontally arranged, and the central axes of the two adjusting cylinders 12 are collinear; when the adjusting cylinder 12 is started, the piston rod of the adjusting cylinder 12 is extended and retracted to adjust the distance between the two grinding knives 111, so as to grind polarizer groups of different sizes and specifications, and has a wide range of applications.

[0059] The working principle of the special-shaped polarizer edge grinding machine of the present application is as follows: during grinding, a person places the stacked polarizer group on the edge grinding table 3, and then activates the vertical cylinder 91, thereby moving the four alignment seats 51 upward to align the alignment plates 52 with the polarizer group. Then, the first electric cylinders 61 on the four alignment seats 51 drive the four alignment plates 52 to move closer to each other, so as to achieve alignment of the four side walls of the polarizer group.

[0060] After the alignment is completed, two of the vertical cylinders 91 are started, so that the two opposite alignment seats 51 move downward, and then the horizontal cylinder 53 is started, so that the pneumatic clamping jaws 54 clamp the binding rope 55 and move it above the polarizer group. While the pneumatic clamping jaws 54 clamp the binding rope 55 and move toward the direction of the polarizer group, the two second electric cylinders 71 are started to drive the pneumatic clamping fingers 72 to move toward the direction of the polarizer group, so as to move the two free ends of the binding rope 55 to the bottom of the polarizer group. Since the two free ends of the binding rope 55 are staggered with each other, the reduction motor 73 can be started, and the reduction motor 73 drives the bidirectional screw rod 74 to rotate, so that the two adjustment blocks 76 on the bidirectional screw rod 74 move away from each other in the adjustment slot 75, and then the two pneumatic clamping fingers 72 move away from each other, so that the two free ends of the binding rope 55 move away from each other, thereby realizing the bundling of the aligned polarizer group, so that when the polarizer group is edged by the grinder 111, it helps to avoid the polarizer group from offsetting and affecting the edge grinding accuracy and edge grinding efficiency.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
