In one embodiment, the present embodiment provides a polarizer peeling apparatus, which mainly comprises a base and a peeling mechanism, wherein the base has a supporting platform 1 for carrying an optical display panel 14, and the peeling mechanism is movably connected to the base along a peeling direction. When the peeling mechanism moves relative to the base along the peeling direction, the polarizer in the optical display panel 14 on the supporting platform 1 can be peeled off to complete peeling of the polarizer.
Wherein the concrete structure of base can set up as required, and wherein supporting platform 1's support direction can be up, also begins down, and when down, can fix through modes such as absorption, when up, can utilize gravity to produce frictional resistance, keeps relatively fixed. Similarly, the side of the optical display panel 14 having the polarizer may be supported, or the side of the optical display panel 14 not having the polarizer may be supported. As shown in the drawings, the supporting direction of the supporting platform 1 is upward, and the side of the optical display panel 14 without the polarizer is supported, and when the optical display panel 14 is placed, the side with the polarizer is upward.
The stripping mechanism mainly comprises a first guide roller 2, a second guide roller 3 and a material receiving device 4, which can be mutually mounted, or can be directly or indirectly mounted on the same structure, such as a movable seat 7 mentioned later. However, it should be ensured that both the first guide roller 2 and the second guide roller 3 can rotate, either actively or passively.
Wherein the first guide roller 2 and the second guide roller 3 are arranged on the same side of the supporting platform 1 to guide the polarizer to be peeled off, and the first guide roller 2 and the second guide roller 3 are oppositely arranged to form a gap for the polarizer to pass through. The first guide roller 2 is disposed behind the second guide roller 3 in a peeling direction, wherein the peeling direction is a direction in which the peeling mechanism gradually peels the polarizer from the substrate of the optical display panel 14 until the polarizer is completely separated, and the first guide roller 2 is disposed behind the second guide roller 3 and moves in a direction of the second guide roller 3 when moving in the peeling direction of the first guide roller 2.
In use, the peeled portion of the polarizer is passed through the nip with one side of the polarizer for attachment to the substrate against the first guide roller 2 and the other side against the second guide roller 3. Because the first guide roller 2 and the second guide roller 3 are used to guide the polarizer peeling. When in use, the first guide roller 2 can be pressed against the substrate (mainly the substrate from which the polarizer is peeled) of the optical display panel 14 at the peeling position and can roll, or a certain gap can be maintained; the second guide roller 3 may be a roller that abuts against the side surface corresponding to the portion of the polarizer that has been peeled off at the peeling position. At this time, the substrate and the polarizer at the peeling position form a separating force by the guiding and limiting action (clamping action) of the first guide roller 2 and the second guide roller 3, so as to be separated.
It should be noted that the first guide roller 2 may or may not roll on the substrate of the optical display panel 14 to press the substrate of the optical display panel 14, but needs to press against the corresponding side of the polarizer and roll relative to the polarizer; and the second guide roller 3 may or may not roll on the side corresponding to the non-peeled part of the polarizer, but needs to be pressed against the side corresponding to the peeled part of the polarizer.
Alternatively, the crack gap and the thickness of the polarizer may be matched, so that two sides of the stripped part of the polarizer respectively abut against the first guide roller 2 and the second guide roller 3 to ensure flatness. When the peeled portion of the polarizer moves in the nip, the first guide roller 2 and the second guide roller 3 follow the rotation to roll on both sides of the polarizer, respectively. The first guide roller 2 and/or the second guide roller 3 can be driven by a driving mechanism to rotate actively; the driving mechanism may not be provided, so that the first guide roller 2 and the second guide roller 3 are driven to rotate, for example, the polarizer may be moved to drive the first guide roller 2 and the second guide roller 3 to rotate, or the peeling mechanism may be moved in the peeling direction to roll the first guide roller 2 and the second guide roller 3, and the latter method is preferred.
Specifically, in operation, the gap between the first guide roller 2 and the supporting surface of the supporting platform 1 may be matched with the thickness of the portion of the optical display panel 14 from which the polarizer is peeled. And the gap between the second guide roller 3 and the supporting surface of the supporting platform 1 can be matched with the thickness of the part of the optical display panel 14 where the polarizer is not peeled off, so that the gap between the second guide roller 3 and the supporting surface of the supporting platform 1 can be made larger than the gap between the first guide roller 2 and the supporting surface of the supporting platform 1. And the gap between the first guide roller 2 and the second guide roller 3 is matched with the thickness of the polarizer. The diameters of the first guide roller 2 and the second guide roller 3 are preferably equal, and are not too large, and the first guide roller and the second guide roller should be correspondingly arranged according to the allowable bending degree of the polarizer, and the smaller the diameter is, the better the diameter is, and if the allowable bending degree of the polarizer is exceeded, the polarizer is easy to bend and break.
One side of second guide roll 3, which is far away from first guide roll 2, is provided with at least one supporting roller assembly 5, supporting roller assembly 5 is used for supporting the middle part between the two ends of second guide roll 3 in an abutting manner, so as to avoid the middle part of second guide roll 3 from bending deformation towards the direction far away from first guide roll 2, namely, radial bending deformation is avoided, so as to ensure that when the large-size polaroid is adapted, the slender second guide roll 3 can be fine in a linear type, and further, in the fine extension direction of the guarantee, the second guide roll 3 is tightly attached to the polaroid, so as to ensure that the large-size polaroid is uniformly stressed everywhere.
Wherein the material receiving device 4 is used for applying a pulling force to the peeled polarizer, and preferably bending the portion of the polarizer passing through the slit toward the second guide roller 3 to ensure that a sufficient peeling angle is formed between the polarizer and the substrate at the peeling position. Here, it is intended to be limited that when the material receiving device 4 has different material receiving modes, at least one of the material receiving modes should be capable of bending the portion of the polarizer passing through the nip toward the second guide roller 3. If the material receiving device 4 is a material receiving roller, the axis of the material receiving roller is at the front side or the rear side of the nip, at least the front side of the material receiving roller is at the front side of the nip, when in use, the polaroid can be wound around from the rear side to the material receiving roller or from the front side to the material receiving roller, and when the polaroid is wound around from the front side (the front side in the peeling direction) of the material receiving roller, the part of the polaroid passing through the nip can be ensured to be bent towards the second guide roller 3.
When the polarizer peeling device is used, the optical display panel 14 is placed on the supporting platform 1, a part of the rear side of the polarizer on the optical display panel 14 is peeled in advance, and the peeled part of the polarizer passes through the gap between the first guide roller 2 and the second guide roller 3, winds forwards on the second guide roller 3, and is connected to the material receiving device 4. Then the peeling mechanism moves forwards as a whole, the material receiving device 4 receives the material, and the first guide roller 2 and the second guide roller 3 guide the polaroid to be peeled off gradually until the peeling is finished. In the stripping process, one side of the second guide roller 3, which is far away from the first guide roller 2, is provided with at least one supporting roller assembly 5, so that the straightness of the second guide roller 3 can be effectively ensured, and the problem of fold fracture in the stripping process of the large-scale polaroid can be avoided. In conclusion, the polarizer stripping device can effectively solve the problem that the large-size polarizer is difficult to strip.
Wherein the supporting roller assembly 5 may include only one supporting roller to abut against the second guide roller 3, but such a supporting effect is not good, and it is still easy to cause the second guide roller 3 to be bent. In this connection, it is preferred here that the supporting roller assembly 5 comprises two supporting feet 51 arranged in a V-shape, each supporting foot 51 being provided with a supporting roller to abut against different circumferential positions of the second guiding roll 3. So that the supporting roller assembly 5 forms a V-shaped groove structure, and any stress in the leading direction can be offset by the corresponding supporting foot 51. At this time, the requirement for the accuracy of the placement position of the support foot 51 is also reduced.
The second guide roller 3 can be separated into a multi-segment structure from one end to the other end, but this may cause a separation part to form a shearing force on the polarizer, so it is preferable here that the roller surface is continuously arranged from one end to the other end of the second guide roller 3, so that the second guide roller 3 is a single roller structure and is arranged in segments, and further the continuity of the side abutted to the polarizer is ensured.
Since the peeled polarizer is mainly supported by the second guide roller 3, the continuity of the first guide roller 2 may not be strictly required, and specifically, the first guide roller 2 may be separated into a plurality of roller segments in the extending direction. The both ends of each section roller body section are all rotated through 6 with the support arm and are connected in order to be supported, and is concrete, can set up the fixed strip that extends along 3 extending direction of second guide roll, and 6 one ends of each support arm are fixed on the fixed strip, and the other end rotates with the roller body section to support roller body section. It should be noted that adjacent roller segments near one end may be pivotally connected to the same support arm 6. It should be noted that the fixing strip may be fixed on the movable seat 7, and may be rigidly fixed, or may be elastically fixed, so that the distance from the supporting surface of the supporting platform 1 and/or the distance from the second guiding roller 3 may be elastically adjusted.
Specifically, wherein can make wherein support rolls be stainless steel bearing, the materials are cheap, and can guarantee the wheel face size precision to guarantee the laminating nature. Wherein the supporting legs 51 preferably comprise a supporting shaft arranged by penetrating a stainless steel bearing and two supporting legs respectively arranged at two ends of the supporting shaft. The legs of both support feet 51 are mounted on a mounting plate which may be connected to the connecting plate 8 later on by screws or bolts.
Furthermore, in order to facilitate the arrangement of each structure, the stripping mechanism may include a movable seat 7, a connecting plate 8, and two rotating flange seats 9 respectively located at two ends of the connecting plate 8 and connected to each other. Wherein, the two ends of the second guide roll 3 are respectively connected with the rotating flange seats 9 at the two ends in a rotating way, and the plurality of supporting roller assemblies 5 are uniformly distributed along the extending direction of the second guide roll 3 and are respectively arranged on the connecting plate 8.
And wherein the rotating flange seat 9 is rotatably connected to the movable seat 7 to enable the second guide roll 3 to be moved away from the first guide roll 2 when rotated. So that the peeled portion of the polarizer passes through the gap between the first guide roller 2 and the second guide roller 3 before working. Wherein the connecting plate 8, the rotary flange seat 9, the second guide roller 3 and the supporting roller assembly 5 form a pressing roller assembly, although the pressing roller assembly can also comprise other structures.
Furthermore, in order to facilitate the rotation of the rotary flange seat 9, a rotation driving mechanism may be provided, and when the rotation driving mechanism is provided or not provided, the manual rotation of the rotary flange seat 9 may be further performed. The driving mechanism for driving the rotary flange seat 9 to rotate can be a motor, but considering that the rotation angle does not need to be too large, the driving mechanism preferably further comprises a first telescopic cylinder 10 and a second telescopic cylinder 11 for driving the rotary flange seat 9 to rotate in different directions; two ends of the first telescopic cylinder 10 are respectively hinged with the rotating flange seat 9 and the movable seat 7, and two ends of the second telescopic cylinder 11 are respectively hinged with the rotating flange seat 9 and the movable seat 7. As shown in fig. 1 and 4, when the first telescopic cylinder 10 is lifted and the second telescopic cylinder 11 is retracted, the pressing roller assembly rotates and presses downwards, and at this time, the first guide roller 2 and the second guide roller 3 are close to a tangent state, so that the gap is formed; and when the first telescopic cylinder 10 retracts and the second telescopic cylinder 11 retracts and rises, the pressing roller assembly rotates and rises, and the first guide roller 2 and the second guide roller 3 move away from each other. Wherein the first telescopic cylinder 10 and the second telescopic cylinder 11 are preferably telescopic cylinders.
Further, the material receiving device 4 may include a steel receiving roller 41, and of course, a guide roller may be optionally provided. The material receiving steel roller 41 is rotatably connected to the movable seat 7, and for convenience of installation and compactness of the mechanism, the rotation axis of the material receiving steel roller 41 and the rotation axis of the rotary flange seat 9 are preferably arranged coaxially and can rotate relative to each other. The pressing roller assembly rotates to rise, the first guide roller 2 and the second guide roller 3 are far away from and move, the lower side of the material receiving steel roller 41 can be well exposed at the moment, and therefore the polaroid stripped from the material receiving steel roller 41 can be conveniently taken down by a worker.
Further, at least one of the rotating flange seats 9 may be provided with a crash pad 12 to prevent the compressing roller assembly from excessively ascending when the compressing roller assembly rotates, so as to avoid reversely impacting the first material receiving roller. Correspondingly, two ends of the fixing strip can be arranged on the movable seat 7.
Further, in order to ensure that the whole peeling mechanism moves smoothly, a driving mechanism may be arranged to drive the peeling mechanism to move so as to peel the polarizer. The driving mechanism for driving the peeling mechanism to walk and the driving mechanism for driving the receiving steel roller 41 to rotate may be two different mechanisms or the same mechanism.
