Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, in particular to a polarizing film cutting equipment. Background Art

[0002] A polarizer is an optical element with polarization effect. It can filter light by selectively absorbing light in certain directions. Different displays or other optical devices may require polarizers of different sizes. Therefore, polarizers need to be cut during the production process. Through laser cutting, polarizers of different sizes can be cut from a complete polarizer to meet different usage requirements.

[0003] The patent with announcement number CN212918091U discloses a polarizer cutting machine, including a working box, a filter box is fixedly connected to the right side of the top of the working box, and the inner cavity of the filter box is fixedly connected with a fine filter screen and an activated carbon filter screen from left to right by screws. By setting the fine filter screen, waste debris can be conveniently filtered, and by setting the activated carbon filter screen, harmful gases can be conveniently filtered. By setting the exhaust fan, the waste debris and smoke generated when the laser head cuts the polarizer can be sucked into the inner cavity of the exhaust fan through the dust hood, and then transported to the filter box through the exhaust pipe. By setting an electric cylinder, the laser head can be moved back and forth, so as to facilitate the cutting of the polarizer. By setting the above structure, it has the advantage of being able to remove dust when cutting the polarizer, and solves the problem that the original device cannot remove dust when cutting the polarizer, thereby avoiding waste debris and smoke from flying and affecting the health of the staff.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The polarizer is placed on a workbench and then cut using a laser head. Since the polarizer is always in contact with the workbench during the cutting process, the cut polarizer remains in its original position and needs to be manually removed and collected. In some large-scale production processes, a large number of polarizers of the same specifications are often required. When a large number of polarizers need to be cut, the number of collection times will increase, which increases the labor intensity of the workers. In addition, usually, in order to facilitate the transportation of multiple cut polarizers, the cut polarizers need to be neatly stacked. After the workers manually remove the polarizers, they also need to manually sort them, which is troublesome and also increases the labor intensity of the workers.

[0006] To this end, the present invention provides a polarizer cutting device. Summary of the invention

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The polarizer cutting device described in the present invention places the left edge of the polarizer to be cut under the left clamping plate, and then manually rotates the threaded rod four to drive the adjustment plate to move horizontally according to the width of the polarizer, so that the right edge of the polarizer can be placed under the right clamping plate, and then rotates the threaded rods three on both sides to make the clamping plate descend to clamp the polarizer, thereby fixing the polarizer and ensuring the stability of the polarizer during cutting.

[0022] 2. The polarizer cutting device described in the present invention utilizes a vacuum adsorption mechanism and an edge-smoothing stacking mechanism to realize automatic collection and neat stacking of the cut polarizers, which is convenient for subsequent unified transportation of the polarizers. At the same time, it also eliminates the need for manual collection and stacking of the cut polarizers, thereby reducing the labor intensity of the workers. Moreover, each time a polarizer is placed, the support block will drop a certain distance to keep the top polarizer at a fixed height. Therefore, the suction cup can place the polarizer at a fixed height each time. The polarizer is put down without having to drop too far, so that the laser cutting head can quickly carry out the next cutting work. Moreover, before the polarizer is placed on the support block, its lower end face will first contact with the upper end face of the expansion rod, and then drive multiple expansion rods to move away from the axis of the fixed ring at the same time. Since in this process, the expansion rod moves from the center position of the polarizer to its edge position, the downward bent edge of the polarizer will be smoothed. Moreover, multiple expansion rods are plugged into each other to form a complete polygon. The expansion rods can fit with each position of the edge of the polarizer, and there will be no dead angle for smoothing. When the edge of the polarizer is smoothed, the polarizer is placed on the support block again. This can avoid the polarizer being squeezed and deformed when it is placed on the support block due to the edge of the polarizer bending downward when the polarizer moves with the suction cup, thereby ensuring the quality of the polarizer. In addition, since the height of the support block is adjusted in real time according to the number of polarizers stacked, the distance between the polarizer being smoothed and the polarizer below it is small, so the smoothed polarizer only needs to drop a short distance to be stacked, avoiding the smoothed polarizer The edge of the sheet bends downward again due to the long distance it has descended, which further ensures the flatness of the polarizer when it is placed. In addition, every time a polarizer is placed, the height of the threaded block is adjusted according to the height of the top polarizer to make it in a suitable position, and the pressing block is driven to rotate so that the pressing block rotates and presses the stacked polarizers, thereby ensuring the stability of the stacked polarizers and avoiding the deviation and slipping of the polarizers due to the displacement of the placement table, further ensuring the neatness of the polarizers and facilitating subsequent transportation and other work.

[0050] Specifically, when the existing polaroid cutter is used, the polaroid is placed on the workbench 1, and then the polaroid is cut by a laser head. Since the polaroid is always in contact with the workbench 1 during the cutting process, the cut polaroid is still in the original position and needs to be manually removed and collected. In some large-scale production processes, a large number of polaroids of the same specifications are often required. When the number of polaroids to be cut is large, the number of collection times will increase accordingly, which increases the labor intensity of the workers. In addition, usually, in order to facilitate the transportation of multiple cut polaroids, the cut polaroids need to be neatly stacked. After the workers manually remove the polaroids, they also need to manually sort them, which is troublesome and also increases the labor intensity of the workers.

[0051] Therefore, in order to solve the above problems, when the present embodiment is used, when it is necessary to cut a plurality of circular polarizers of the same specifications from a complete polarizer, after the polarizer is pressed and positioned, the motor 1 9 drives the threaded rod 2 7 to rotate, the motor 8 53 drives the threaded rod 1 4 to rotate, and the electric push rod 1 5 drives the connecting plate 40 to rise and fall, so that the position of the laser cutting head 44 in the X, Y, and Z axis directions can be adjusted, and according to the diameter of the circular polarizer to be cut, the motor 6 41 drives the connecting rod 4 42 and the connecting rod 5 43 to rotate, and the distance between the laser cutting head 44 and the axis center of the lifting plate 56 is adjusted, and then the laser cutting head 44 is started, and the motor 7 50 drives the gear 2 51 to rotate. The gear ring 2 52 and the laser cutting head 44 are rotated to cut the polarizer. When a circle is cut out on the polarizer, the laser cutting head 44 is driven away from the polarizer. Then, the electric push rod 2 48 is used to drive the suction cup 45 to descend. The suction cup 45 contacts the middle of the polarizer. Then, the vacuum pump 47 is used to evacuate the suction cup 45, so that the suction cup 45 can hold the cut polarizer. Then, the electric push rod 1 5 is used to drive the suction cup 45 to rise again, so that the cut polarizer moves upward. Then, the transverse plate 54 is driven to move to the left until the polarizer is above the placement table 8 and the axis of the polarizer coincides with the axis of the fixing ring 17. Then, the polarizer is driven down again. At the same time, according to the polarizer The motor 5 36 drives the turntable 37 to rotate, so that the multiple connecting rods 3 38 can rotate at the same time, so that the slider 1 23, the slider 3 26, and the slider 2 25 can move radially on the placement table 8, and the telescopic rod 27 can be extended and retracted until the support block 24 is aligned with the edge of the polarizer. At the same time, the motor 28 drives the threaded rod 5 29 to rotate, so that the support block 24 on one side rises, and under the action of the multiple telescopic rods 27, the multiple support blocks 24 rise at the same time and approach the polarizer until the polarizer is supported, and then the solenoid valve on the suction cup 45 is opened to allow air to enter the interior of the suction cup 45, so that the polarizer can be separated from the suction cup 45 and placed on the support block 24. At this time, the The first polarizer is placed, and then the above operation is repeated, and the polarizers can be neatly placed in the same place by stacking them, thereby realizing automatic collection and stacking of the cut polarizers, which is convenient for subsequent unified transportation of the polarizers. At the same time, it also saves the process of manually collecting and stacking the cut polarizers, reducing the labor intensity of the workers, and each time a polarizer is placed, the support block 24 will drop a distance to keep the top polarizer at a fixed height. Therefore, the suction cup 45 can put down the polarizer at a fixed height every time without dropping too much distance, so that the laser cutting head 44 can quickly perform the next cutting work;

[0052] Since the polarizer is relatively soft, when the polarizer moves with the suction cup 45, the edge of the polarizer may bend downward. When the edge of the polarizer is bent, placing it on the support block 24 will cause the edge of the polarizer to be squeezed and deformed, thereby affecting the quality of the polarizer. Therefore, in order to avoid this situation, before the polarizer is placed on the support block 24, its lower end surface will first contact the upper end surface of the expansion rod 22, and then the motor 955 will be used to drive the connecting rod 19 and the connecting rod 20 to rotate, and under the rotation of the gear 139 and the ring gear 18, multiple connecting rods 19 and connecting rods 20 are rotated at the same time, so that multiple expansion rods 22 are simultaneously away from the axis of the fixing ring 17. Since in this process, the expansion rod 22 moves from the center position of the polarizer to its edge position, the downward bent edge of the polarizer will be smoothed, and multiple expansion rods 22 will be The rods 22 are plugged into each other to form a complete polygon. The expansion rods 22 can fit with each position of the edge of the polarizer without any dead angle for smoothing. When the edge of the polarizer is smoothed, the polarizer is placed on the support block 24 again, which can avoid the polarizer edge being squeezed and deformed after being placed on the support block 24 due to the edge of the polarizer bending downward when the polarizer moves with the suction cup 45, thereby ensuring the quality of the polarizer. In addition, since the height of the support block 24 is adjusted in real time according to the number of stacked polarizers, the distance between the polarizer being smoothed and the polarizer below it is small, so the smoothed polarizer only needs to be lowered a short distance to be stacked, thereby avoiding the situation where the edge of the smoothed polarizer is bent downward again due to a long distance of descent, further ensuring the flatness of the polarizer when it is placed.

[0053] When the polarizers are stacked on the support block 24, the movement of the placement table 8 may cause the polarizers to shift. Therefore, every time a polarizer is placed, the motor three 31 is used to drive the threaded rod six 34 to rotate according to the height of the top polarizer, and the height of the threaded block 32 is adjusted to make it in a suitable position, and the motor four 35 is used to drive the pressing block 30 to rotate, so that the pressing block 30 rotates and presses the stacked polarizers, thereby ensuring the stability of the stacked polarizers, avoiding the polarizers from shifting or sliding due to the displacement of the placement table 8, and further ensuring the neatness of the polarizers, which is beneficial to subsequent transportation and other work.

[0054] Working principle: place the left edge of the polarizer to be cut under the left clamping plate 11, and then manually rotate the threaded rod 4 16 according to the width of the polarizer to drive the adjustment plate 14 to move horizontally, so that the right edge of the polarizer can be placed under the right clamping plate 11, and then rotate the threaded rods 3 13 on both sides to lower the clamping plate 11 to clamp the polarizer, thereby achieving the fixation of the polarizer and ensuring the stability of the polarizer during cutting. The threaded rod 2 7 is driven by the motor 1 9 to rotate, the motor 8 53 drives the threaded rod 1 4 to rotate, and the electric push rod 1 5 drives the connecting plate 40 to rise and fall, so as to adjust the position of the laser cutting head 44 in the X, Y, and Z axis directions, and according to the diameter of the circular polarizer to be cut, the motor 6 41 is used to drive the connecting rod 4 42 and the connecting rod The five gears 43 rotate to adjust the distance between the laser cutting head 44 and the axis of the lifting plate 56, and then start the laser cutting head 44, and drive the motor seven 50 to drive the gear two 51 to rotate, so that the ring gear two 52 and the laser cutting head 44 rotate to cut the polarizer. After a circle is cut out on the polarizer, the laser cutting head 44 is driven away from the polarizer, and then the electric push rod two 48 is used to drive the suction cup 45 to descend, and the suction cup 45 contacts the middle of the polarizer, and then the vacuum pump 47 is used to empty the suction cup 45 and extract it, so that the suction cup 45 can suck the cut polarizer, and then the electric push rod one 5 is used again to drive the suction cup 45 to rise, so that the cut polarizer moves upward, and then the transverse plate 54 is driven to move to the left until the polarizer is on the placement table 8. At the same time, according to the size of the polarizer, the motor 5 36 is used to drive the turntable 37 to rotate, so that the multiple connecting rods 3 38 can be rotated at the same time to make the slider 1 23, the slider 3 26, and the slider 25 move radially on the placement table 8, and the telescopic rod 27 is extended and retracted until the support block 24 is aligned with the edge of the polarizer. At the same time, the motor 28 is used to drive the threaded rod 5 29 to rotate to make the support block 24 on one side rise, and under the action of the multiple telescopic rods 27, the multiple support blocks 24 rise at the same time and approach the polarizer until the polarizer is supported, and then the solenoid valve on the suction cup 45 is opened to allow air to enter the suction cup 45, so that the polarizer and the suction cup 45 can be aligned. Separate and place on the support block 24. At this time, the first polarizer can be placed. Then repeat the above operation to neatly place the polarizers in the same place by stacking them, thereby realizing automatic collection and stacking of the cut polarizers, which is convenient for subsequent unified transportation of the polarizers. At the same time, it also saves the process of manually collecting and stacking the cut polarizers, reducing the labor intensity of the workers. Moreover, every time a polarizer is placed, the support block 24 will drop a distance to keep the top polarizer at a fixed height. Therefore, the suction cup 45 can put down the polarizer at a fixed height every time without dropping too much distance, so that the laser cutting head 44 can quickly perform the next cutting work.Since the polarizer is relatively soft, when the polarizer moves with the suction cup 45, the edge of the polarizer may be bent downward. When the edge of the polarizer is bent, placing it on the support block 24 will cause the edge of the polarizer to be squeezed and deformed, thereby affecting the quality of the polarizer. Therefore, in order to avoid this situation, before the polarizer is placed on the support block 24, its lower end surface will first contact the upper end surface of the expansion rod 22, and then the motor 955 will be used to drive the connecting rod 19 and the connecting rod 20 to rotate, and under the rotation of the gear 139 and the ring gear 18, the multiple connecting rods 11 and 12 will be rotated. 9 and the connecting rod 20 rotate simultaneously, so that the multiple expansion rods 22 are simultaneously away from the axis of the fixing ring 17. Since in this process, the expansion rods 22 move from the center position of the polarizer to the edge position thereof, the downward bent edge of the polarizer will be smoothed, and the multiple expansion rods 22 are plugged into each other to form a complete polygon. The expansion rods 22 can fit with each position of the edge of the polarizer without any dead angle for smoothing. When the edge of the polarizer is smoothed, the polarizer is placed on the supporting block 24 again, so that when the polarizer moves with the suction cup 45, the edge of the polarizer is bent downward, which can avoid the guide After the polarizer is placed on the support block 24, the edge of the polarizer is squeezed and deformed, which ensures the quality of the polarizer. In addition, since the height of the support block 24 is adjusted in real time according to the number of polarizers stacked, the distance between the polarizer being smoothed and the polarizer below it is small, so the smoothed polarizer only needs to be lowered a short distance to be stacked, avoiding the situation where the edge of the smoothed polarizer is bent downward again due to being lowered a long distance, further ensuring the flatness of the polarizer when it is placed; when the polarizer is stacked on the support block 24, it may The polarizers may be offset due to the movement of the placement table 8. Therefore, every time a polarizer is placed, the motor 31 is used to drive the threaded rod 6 34 to rotate according to the height of the top layer of polarizers, and the height of the threaded block 32 is adjusted to make it in a suitable position. The motor 4 35 is used to drive the pressing block 30 to rotate and press the stacked polarizers, thereby ensuring the stability of the stacked polarizers, avoiding the polarizers from being offset or slipping due to the displacement of the placement table 8, and further ensuring the neatness of the polarizers, which is beneficial to subsequent transportation and other work. ;
