Description

Technical Field

[0001] The present invention relates to the field of polarizer processing, and particularly to a polarizer peeling machine and a peeling method thereof. Background Art

[0002] A polarizer is a thin film material that can selectively block light with a specific polarization direction. Its main function is to convert non-polarized natural light into polarized light. The full name of the polarizer is a polarized light sheet, and the imaging of a liquid crystal display must rely on polarized light. In a liquid crystal display, the polarizer needs to be closely attached to the liquid crystal glass, and an accurate cutting direction needs to be determined. This is because when processing the polarizer, the absorption axis angle needs to be measured, and this angle will directly affect the selection of the cutting direction. If the absorption axis angle is measured inaccurately, resulting in an incorrect cutting direction, it will greatly affect the performance of the optical film.

[0003] During the process of attaching the polarizer, situations such as poor attachment effect, insufficient attachment accuracy, the appearance of bubbles, and scratching of the polarizer may occur, all of which require the already attached polarizer to be peeled off from the glass substrate and then reattached. Or during the use of the display, in the case of damage to the polarizer, etc., the polarizer also needs to be replaced, thus requiring the polarizer to be removed from the liquid crystal glass.

[0004] Currently, for smaller liquid crystal glasses, they are manually scraped off. For larger liquid crystal glasses, a winding machine is used. An operator peels off one corner of the polarizer manually, and then clamps the peeled polarizer in the machine. The rollers of the machine drive the polarizer to be peeled off from the liquid crystal glass, and it is necessary to manually tear the polarizer, making the operation more difficult. There is also a peeling machine that directly shovels up the polarizer, but for larger liquid crystal glasses, it is not easy to fix, and it is prone to bending or offset, resulting in a poor peeling effect of the polarizer, and thus it is relatively difficult to directly shovel off the polarizer. Summary of the Invention

[0026] Embodiment: A polarizer peeling machine, as Figures 1 - 4As shown in the figure, it includes a machine body 1, a mobile platform 11, a control component 12, an electric slide rail 13 and a cylinder 14. An electric slide rail 13 is arranged on the machine body 1, and a mobile platform 11 is arranged on the electric slide rail 13. The mobile platform 11 is slidably connected to the machine body 1. A control component 12 is arranged on the machine body 1. The control component 12 includes a plurality of control buttons. A cylinder 14 is installed on the mobile platform 11. It also includes a peeling blade 15, a pressing component 2, an alignment component 3 and a pushing component 4. The bottom of the cylinder 14 is connected to the peeling blade 15. Inclined blades are arranged on both sides of the front end of the peeling blade 15. The peeling blade 15 is slidably connected to the mobile platform 11. A pressing component 2 for pressing the liquid crystal glass is arranged at the front end of the mobile platform 11. An alignment component 3 for restricting the position of the liquid crystal glass is arranged on the machine body 1. A pushing component 4 is jointly arranged on the machine body 1 and the mobile platform 11, which is used to release the restriction of the alignment component 3 on the liquid crystal glass.

[0027] As Figure 3 , Figure 5 and Figure 6 shown in the figure, the pressing component 2 includes a rotating frame 21, a telescopic rod 22, a first elastic member 23, a pressing roller 24, a fixing piece 25, a limiting rod 26, a handle 261, a second elastic member 27 and a limiting disc 28. The rotating frame 21 is rotatably connected to the mobile platform 11. A telescopic rod 22 is slidably connected to the rotating frame 21. The bottom of the telescopic rod 22 is provided with a pressing roller 24. The bottom of the pressing roller 24 has already contacted the machine body 1. A first elastic member 23 is sleeved on the telescopic rod 22. One end of the first elastic member 23 is connected to the rotating frame 21, and the other end is connected to the pressing roller 24. Fixing pieces 25 are connected to the left and right sides of the mobile platform 11. A limiting rod 26 is slidably connected to the fixing pieces 25. Limiting discs 28 are arranged at both ends of the rotating frame 21. Positioning holes 281 and limiting holes 282 are formed in the limiting discs 28. The included angle between the positioning holes 281 and the limiting holes 282 and the center of the limiting discs 28 is 60 degrees, and the depth of the limiting holes 282 is greater than that of the positioning holes 281. The limiting holes 282 are provided with vertical parts. The limiting rod 26 and the limiting discs 28 are in limiting cooperation. A second elastic member 27 is sleeved on the limiting rod 26. One end of the second elastic member 27 is connected to the limiting rod 26, and the other end is connected to the fixing piece 25. A handle 261 is arranged on the limiting rod 26, and the handle 261 has been rounded.

[0028] As Figure 7 and Figure 8 shown in the figure, the alignment component 3 includes a sliding frame 31, an alignment frame 32, a threaded rod 33 and a third elastic member 34. The sliding frame 31 is slidably connected to the left and right parts of the machine body 1. Alignment frames 32 are slidably connected to the adjacent ends of the two sliding frames 31. The threaded rod 33 is threadedly connected to the sliding frame 31. The end of the threaded rod 33 is rotatably connected to the alignment frame 32. A third elastic member 34 is sleeved on the sliding frame 31. One end of the third elastic member 34 is connected to the sliding frame 31, and the other end is connected to the machine body 1. The third elastic member 34 is always in a compressed state.

[0029] As Figure 3 , Figure 4 and Figure 7 shown, the pushing component 4 includes a bent plate 41, a connecting plate 42 and a triangular block 43. The bent plate 41 is connected to the left and right sides of the moving table 11. The bottom of the connecting plate 42 is connected to one side where the two sliding frames 31 are separated from each other. The top of the connecting plate 42 is connected with a triangular block 43. The front side of the triangular block 43 is a straight surface and the rear side is an inclined surface. The triangular block 43 is in extrusion fit with the bent plate 41. The distance between the front end of the bent plate 41 and the front end of the machine body 1 is less than the distance between the front end of the peeling blade 15 and the front end of the machine body 1.

[0030] The staff places the liquid crystal glass from which the polarizer needs to be peeled on the machine body 1, squeezes the liquid crystal glass through the alignment component 3 so that the position of the liquid crystal glass is in the exact middle of the machine body 1. Subsequently, by pressing the button of the control component 12, the strokes of the electric slide rail 13 and the air cylinder 14 are set. The electric slide rail 13 moves the moving table 11 forward, and at the same time, the piston rod of the air cylinder 14 pushes the peeling blade 15 to slide vertically downward. At this time, the pressing component 2 will squeeze the rear end of the liquid crystal glass to ensure that the liquid crystal glass adheres to the machine body 1. Moreover, after the peeling blade 15 descends to the preset height, the air cylinder 14 is locked, and the electric slide rail 13 moves slowly, so that the peeling blade 15 contacts the liquid crystal glass, and peels the polarizer during the forward movement. After moving a certain distance, the peeling blade 15 has completely contacted the liquid crystal glass, and the bottom of the peeling blade 15 squeezes the liquid crystal glass. At this time, the rotating frame 21 is lifted, and the position of the rotating frame 21 is restricted through the limiting hole 282, which is convenient for the staff to grab the gradually peeled polarizer. Subsequently, the pushing component 4 pushes the alignment component 3 to ensure that the peeling blade 15 will not contact the alignment component 3. After the electric slide rail 13 reaches the maximum stroke, the front end of the peeling blade 15 completely passes through the liquid crystal glass, and the staff removes the peeled polarizer. Subsequently, the electric slide rail 13 moves the moving table 11 backward. After the moving table 11 is reset backward, the liquid crystal glass is removed. During the backward movement of the moving table 11, the piston rod of the air cylinder 14 pulls the peeling blade 15 to rise, and the rotating frame 21 is put down to complete the peeling of the polarizer this time. Since the two ends of the front side of the peeling blade 15 extend outward, the two ends of the peeling blade 15 will contact the polarizer first, and the contact area gradually expands from small, so the resistance is small when just contacting, and the driving force on the liquid crystal glass is small, and the liquid crystal glass will not bend. When the contact area is subsequently expanded, the peeling blade 15 can squeeze the liquid crystal glass, and the liquid crystal glass will not bend; Before placing the liquid crystal glass, turn the threaded rod 33 on the sliding frame 31 according to the width of the liquid crystal glass to ensure that the distance between the two alignment frames 32 is less than the width of the liquid crystal glass. Then, pull the sliding frame 31 to both sides. The sliding frame 31 drives the alignment frame 32 to move, compressing the third elastic member 34. After placing the liquid crystal glass, make the front end of the liquid crystal glass closely adhere to the machine body 1. Then, release the sliding frame 31, and the third elastic member 34 rebounds. The alignment frame 32 contacts both sides of the liquid crystal glass, squeezing the liquid crystal glass from both sides to make the liquid crystal glass move closer to the middle. When the forces on both sides are equal, the liquid crystal glass is aligned with the middle of the machine body 1. Thus, when the inclined surface of the peeling blade 15 contacts the polarizer, both sides are simultaneously stressed, and the liquid crystal glass will not shift, ensuring the smooth progress of the process of peeling the polarizer; Before the peeling blade 15 contacts the polarizer, the lower pressing roller 24 contacts the middle of the rear end of the polarizer. When the lower pressing roller 24 contacts, the compressed first elastic member 23 will squeeze the lower pressing roller 24, so that the rear end of the liquid crystal glass adheres to the machine body 1. Before the peeling blade 15 contacts the polarizer, the liquid crystal glass will not bend and warp, maintaining the state of adhering to the machine body 1, so that it can accurately cut into the bottom of the polarizer and peel off the polarizer. Moreover, during the forward movement of the moving table 11, when the peeling blade 15 completely cuts into the polarizer, turn up the rotating frame 21. Thus, the telescopic rod 22 and the lower pressing roller 24 also rotate upward, and the first elastic member 23 rebounds. The rotating frame 21 drives the limiting disks 28 on both sides to rotate. The limiting disk 28 squeezes the limiting rod 26, and the limiting rod 26 leaves the positioning hole 281. The compressed second elastic member 27 pushes the limiting rod 26 to closely adhere to the limiting disk 28. When the rotating frame 21 rotates 60 degrees, the second elastic member 27 pushes the limiting rod 26 to insert into the limiting hole 282 of the limiting disk 28. At this time, the staff feels the resistance and the rotating frame 21 cannot rotate. Then, release the rotating frame 21. At this time, the peeled polarizer has warped. The staff grabs the peeled end of the polarizer until the polarizer is completely peeled off. After the moving table 11 resets, pull out the limiting rod 26. The limiting rod 26 leaves the limiting hole 282, and the rotating frame 21 freely falls and flips downward to reset. After releasing the limiting rod 26, the second elastic member 27 pushes the limiting rod 26 to re-insert into the positioning hole 281. The positioning hole 281 is a hemispherical groove, and the opening is rounded. The hemisphere at the end of the limiting rod 26 can slide directly, while the depth of the limiting hole 282 is greater than that of the positioning hole 281 and is provided with a horizontal part. Therefore, after the limiting rod 26 is inserted into the limiting hole 282, the rotating disk cannot rotate; During the movement of the mobile station 11, the distance between the front end of the bending plate 41 and the front end of the body 1 is less than the distance between the front end of the peeling blade 15 and the front end of the body 1. Thus, when the bending plate 41 contacts the triangular block 43, the peeling blade 15 does not contact the alignment assembly 3. The front end of the bending plate 41 contacts the triangular block 43 at the top of the connecting plate 42. The front side of the triangular block 43 is a straight surface and the rear side is an inclined surface. Therefore, the bending plate 41 presses the triangular block 43, causing the sliding frame 31 to move to both sides. And after the movement, the distance between the two alignment frames 32 is greater than the width of the peeling blade 15, so as to ensure that the peeling blade 15 does not contact the alignment assembly 3 when peeling the polarizer. The moving sliding frame 31 further compresses the third elastic member 34, causing the alignment frame 32 to disengage from the liquid crystal glass. During the reset process of the mobile station 11, the bending plate 41 disengages from the triangular block 43. Subsequently, the third elastic member 34 rebounds, and the resilience causes the sliding frame 31 and the alignment frame 32 to slide back to their original positions.

[0031] As Figure 5 and Figure 6 shown, it further includes a flipping assembly 5. The flipping assembly 5 includes a flipping gear 51, a support frame 52, a short rack 53, a pressing frame 541, a double-sided inclined block 542, a guide rod 543, and a fourth elastic member 544. A flipping gear 51 is sleeved on the limit disk 28. The support frame 52 is connected to the left and right sides in the middle of the body 1. A short rack 53 is connected to the top of the support frame 52. The short rack 53 meshes with the flipping gear 51. The number of teeth of the short rack 53 is one-sixth of the number of teeth of the flipping gear 51. A guide rod 543 is connected to the support frame 52. A pressing frame 541 is slidably connected to the front end of the support frame 52. The pressing frame 541 is slidably connected to the guide rod 543. A fourth elastic member 544 is sleeved on the guide rod 543. One end of the fourth elastic member 544 is connected to the support frame 52, and the other end is connected to the pressing frame 541. Double-sided inclined blocks 542 are connected to the upper and lower ends of the adjacent ends of the two pressing frames 541. The double-sided inclined blocks 542 are in pressing cooperation with the handle 261.

[0032] During the forward movement of the mobile station 11, the flipping gear 51 meshes with the short rack 53. Since the number of teeth of the short rack 53 is one-sixth of the number of teeth of the flipping gear 51, the flipping gear 51 rotates 60 degrees, so the rotating frame 21 also rotates 60 degrees, causing the pressing roller 24 to move away from the polarizer and not blocking the peeled polarizer from flipping up, facilitating the staff to grab the polarizer. At the same time, after the limiting disc 28 rotates 60 degrees, the limiting rod 26 is inserted into the limiting hole 282, so there is no need to manually lift the rotating frame 21. And after passing through the short rack 53, the handle 261 of the limiting rod 26 contacts the double-sided inclined block 542. Since inclined surfaces are provided at both the front and rear ends of the double-sided inclined block 542 and the limiting rod 26 cannot penetrate deeper into the limiting hole 282, the handle 261 squeezes the double-sided inclined block 542 to move to both sides, the extrusion frame 541 moves along the guide rod 543, and at the same time the fourth elastic member 544 is stretched. After the handle 261 passes through the double-sided inclined block 542, the fourth elastic member 544 rebounds, and the double-sided inclined block 542 slides back to its original position along the guide rod 543. When the mobile station 11 moves backward, the handle 261 first contacts the double-sided inclined block 542. Since the two extrusion frames 541 cannot slide towards the middle, when the handle 261 passes through the double-sided inclined block 542, it slides along the inclined surface of the double-sided inclined block 542 towards both ends, pulling the limiting rod 26 to slide a certain distance, compressing the second elastic member 27, aligning the spherical ball of the limiting rod 26 with the vertical part of the limiting hole 282. Subsequently, when the flipping gear 51 meshes with the short rack 53, the limiting disc 28 can be rotated. Thus, after the mobile station 11 is reset, the rotating frame 21 is also reset, and the pressing roller 24 contacts the machine body 1, and there is no need to manually pull the limiting rod 26.

[0033] As Figure 4 、 Figure 7 and Figure 9 shown, it further includes a transmission rack 6, a bearing 61 and a transmission gear 62. The transmission rack 6 is connected to the sliding frame 31, a bearing 61 is arranged in the middle of the front end of the machine body 1, and a transmission gear 62 is rotatably connected to the bearing 61. The transmission gear 62 meshes with the transmission rack 6.

[0034] The transmission rack 6 moves along with the sliding frame 31. Through the transmission of the transmission gear 62, the sliding frames 31 on both sides move more smoothly and the alignment position is more accurate.
