In one embodiment, the present embodiment provides a polarizer peeling apparatus, mainly including a base having a supporting platform 1 for carrying an optical display panel 14, and a peeling mechanism movably connected to the base along a peeling direction. When the stripping mechanism moves relative to the base along the stripping direction, the polaroid in the optical display panel 14 on the supporting platform 1 can be torn away, so that stripping of the polaroid can be completed.
The base concrete structure can be arranged according to the needs, wherein the supporting direction of the supporting platform 1 can be upward, and also starts to be downward, when downward, the base concrete structure can be fixed in a manner of adsorption and the like, and when upward, the base concrete structure can utilize gravity to generate friction resistance and is kept relatively fixed. Also, the side of the optical display panel 14 having the polarizer may be supported, or the side of the optical display panel 14 having no polarizer may be supported. As shown in the drawings, in which the supporting direction of the supporting platform 1 is upward and the side of the optical display panel 14 having no polarizer is supported, the side having the polarizer is disposed upward when the optical display panel 14 is placed.
The stripping mechanism mainly comprises a first guide roller 2, a second guide roller 3 and a material receiving device 4, and can be mutually installed, or can be directly or indirectly installed on the same structure, such as a movable seat 7 mentioned later. However, it is necessary to ensure that the first guide roller 2 and the second guide roller 3 are rotatable, either actively or passively.
Wherein the first guide roller 2 and the second guide roller 3 are disposed at the same side of the support platform 1 to guide the polarizer to be peeled off, and the first guide roller 2 and the second guide roller 3 are disposed opposite to each other so that a nip for passing the polarizer is formed therebetween. The first guide roller 2 is disposed at the rear side of the second guide roller 3 in a peeling direction, wherein the peeling direction means that when the peeling mechanism moves in the peeling direction, the polarizer can be driven to gradually peel from the substrate of the optical display panel 14 until the polarizer is completely separated, and the first guide roller 2 is disposed at the rear side of the second guide roller 3 and means that when the first guide roller 2 moves in the peeling direction, the first guide roller moves in the direction of the second guide roller 3.
In use, the peeled portion of the polarizer is passed through the nip, with one side of the polarizer for connecting the substrate being directed toward the first guide roller 2 and the other side being directed toward the second guide roller 3. Since the first guide roller 2 and the second guide roller 3 serve to guide the polarizer peeling. In use, the first guide roller 2 may abut against the substrate (mainly, the polarizer portion is peeled off from the substrate) of the optical display panel 14 at the peeling position, and may roll, or may maintain a certain gap; the second guide roller 3 may be abutted against a corresponding side of the peeled portion of the polarizer at the peeling position. At this time, the substrate at the peeling position and the polarizer are separated by the guiding and limiting action (clamping action) of the first guiding roller 2 and the second guiding roller 3 to form a separating force.
It should be noted that, the first guide roller 2 may be made to roll on or off 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 against it; and the second guide roller 3 may or may not roll on the side corresponding to the portion of the polarizer that is not peeled off, but needs to be pressed against the side corresponding to the portion of the polarizer that is peeled off.
Alternatively, the slit may be disposed in cooperation with the thickness of the polarizer, so that both sides of the portion from which the polarizer has been peeled are respectively abutted 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 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 actively rotate; the driving mechanism may not be provided, so that the first guide roller 2 and the second guide roller 3 passively follow rotation, 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 along the peeling direction, so that the first guide roller 2 and the second guide roller 3 roll, and the latter is preferable.
Specifically, in operation, the gap between the first guide roller 2 and the support surface of the support 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 may be matched with the thickness of the portion of the optical display panel 14 where the polarizer is not peeled, so that the gap between the second guide roller 3 and the supporting surface of the supporting platform 1 may 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 should not be too large, and should be set correspondingly according to the allowable bending degree of the polarizer, and if the smaller the better, the more the allowable bending degree of the polarizer is exceeded, the polarizer is easy to bend and break.
One side that second guide roll 3 kept away from first guide roll 2 is provided with at least one support roller component 5, support roller component 5 is used for carrying out the butt to the middle part between the second guide roll 3 both ends and supports to avoid the middle part of second guide roll 3 to keep away from the direction bending deformation of first guide roll 2, avoid radial bending deformation promptly, when guaranteeing to adapt to jumbo size polaroid, the assurance straight line type that elongated second guide roll 3 can be fine, and then fine assurance extension direction is last, closely laminating between second guide roll 3 and the polaroid, in order to guarantee that jumbo size polaroid everywhere atress is even.
Wherein the material receiving device 4 is used for applying pulling force to the stripped polaroid, and preferably the part of the polaroid passing through the crack is bent towards the second guide roller 3 so as to ensure that the stripping position has enough stripping angle between the polaroid and the substrate. It is intended here that, when the receiving device 4 has different receiving modes, at least one receiving mode should be such that bending of the portion of the polarizer passing through the nip towards the second guiding roller 3 is achieved. If the receiving device 4 is a receiving roller, the axis of the receiving roller is at the front side or the rear side of the seam, at least the front side of the receiving roller is at the front side of the seam, when in use, the polarizer can be wound to the receiving roller from the rear side, or can be wound to the receiving roller from the front side, and when the front side (the front side in the stripping direction) of the receiving roller is wound on the receiving roller, the polarizer can be ensured to be bent to the second guide roller 3 from the part where the seam passes through.
When the above polarizer peeling apparatus is used, the optical display panel 14 is placed on the support platform 1, and 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 is passed through the nip between the first guide roller 2 and the second guide roller 3 and wound forward on the second guide roller 3, and then connected to the material receiving apparatus 4. The peeling mechanism is then moved forward as a whole while the collecting device 4 is collecting the polarizer, and the first guide roller 2 and the second guide roller 3 guide the polarizer to be peeled gradually until the peeling is completed. In the peeling process, at least one supporting roller assembly 5 is arranged on one side, away from the first guiding roller 2, of the second guiding roller 3, so that the straightness of the second guiding roller 3 can be effectively ensured, and the problem of fold fracture in the large-scale polarizer peeling process is avoided. In conclusion, the polaroid stripping device can effectively solve the problem that the large-size polaroid is difficult to strip.
Wherein the supporting roller assembly 5 may comprise only one supporting roller to be abutted against the second guide roller 3, but such a supporting effect is not good and still easily causes the second guide roller 3 to bend. Based on this, it is preferable here that the supporting roller assembly 5 includes two supporting legs 51 arranged in a V-shape, each supporting leg 51 being provided with a supporting roller to be abutted against a circumferentially different position of the second guide roller 3. So that the supporting roller assembly 5 forms a V-shaped groove structure, and any direction of force in advance can be counteracted by the corresponding supporting leg 51. At this time, the accuracy of the arrangement position of the support legs 51 is also lowered.
The second guiding roller 3 may be separated into multiple sections from one end to the other end, but this may result in a separation, and form a shearing force on the polarizer, so it is preferable that the second guiding roller 3 is continuously disposed from one end to the other end, so that the second guiding roller 3 is of a single roller structure, and is separately disposed in sections, thereby ensuring continuity with the abutting side of the polarizer.
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 body sections in the extending direction. Both ends of each roller body section are rotatably connected with the supporting arms 6 to be supported, specifically, fixing strips extending along the extending direction of the second guide roller 3 can be arranged, one end of each supporting arm 6 is fixed on the fixing strips, and the other end of each supporting arm is rotatably connected with the roller body section to support the roller body section. It should be noted that the end of the adjacent roller section close to each other may be rotatably connected to the same support arm 6. It should be noted that the fixing strip may be fixed to the movable base 7, 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 guide roller 3 may be elastically adjusted.
Specifically, wherein can make wherein the backing roll be stainless steel bearing, the material is cheap, and can guarantee wheel face dimensional accuracy to guarantee the laminating nature. The supporting leg 51 preferably comprises a supporting shaft penetrating through the stainless steel bearing and two supporting legs respectively arranged at two ends of the supporting shaft. The support legs of both support feet 51 are mounted on a mounting plate which can be connected to the later connection plate 8 by means of screws or bolts.
Further, in order to facilitate the arrangement of the structures, the stripping mechanism may comprise a movable seat 7, a connecting plate 8 and two rotary flange seats 9 respectively located at two ends of the connecting plate 8 and connected with each other. Wherein the two ends of the second guiding roller 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 guiding roller 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 roller 3 to be moved away from the first guide roller 2 when rotated. Before the work, the polarizer-peeled portion passes through the gap between the first guide roller 2 and the second guide roller 3. 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, and the pressing roller assembly can also comprise other structures.
Further, 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, the manual rotary flange seat 9 may be further driven to rotate. The driving mechanism for driving the rotary flange seat 9 to rotate can be a motor, but in view of the fact that the rotation angle does not need to be too large, the rotary flange seat 9 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; the two ends of the first telescopic cylinder 10 are respectively hinged with the rotary flange seat 9 and the movable seat 7, and the two ends of the second telescopic cylinder 11 are respectively hinged with the rotary 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 is rotated and pressed down, and the first guide roller 2 and the second guide roller 3 are in a nearly tangential state to form the crack; while the first telescopic cylinder 10 is retracted and the second telescopic cylinder 11 is retracted and raised, at which time the press roll assembly is rotated and raised, the first guide roll 2 and the second guide roll 3 are moved away from each other. Wherein the first telescopic cylinder 10 and the second telescopic cylinder 11 are preferably telescopic cylinders.
Further, it is possible to include the receiving device 4 with a receiving steel roller 41, and of course, a guide roller may be optionally provided. The receiving steel roller 41 is rotatably connected to the movable seat 7, wherein the rotation axis of the receiving steel roller 41 and the rotation axis of the rotary flange seat 9 are preferably coaxially arranged and rotatable relative to each other for the convenience of installation and compactness of the mechanism. At the rotatory rising of pressing roller subassembly, first guide roll 2 and second guide roll 3 keep away from mutually and remove, the steel roller 41 downside of receiving that can be fine at this moment to make things convenient for the staff to take off the polaroid of peeling off from receiving steel roller 41.
Further, at least one of the rotary flange seats 9 may be provided with a bump pad 12 to prevent excessive rising of the pressing roller assembly during the rotational rising, so as to avoid reversely striking the first receiving roller structure. Correspondingly, two ends of the fixed strip can be arranged on the movable seat 7.
Further, in order to ensure that the whole stripping mechanism moves smoothly, a driving mechanism can be arranged to drive the stripping mechanism to move so as to strip the polaroid. The driving mechanism for driving the peeling mechanism to travel and the driving mechanism for driving the receiving steel roller 41 to rotate can be two different mechanisms or the same mechanism. If the peeling mechanism is used, the peeling mechanism is driven to the travelling mechanism of the peeling mechanism and the material receiving steel roller 41 through different driving mechanisms respectively.
Specifically, the automatic feeding and discharging device can further comprise a driving motor 15, wherein the driving motor 15 is arranged on the movable seat 7, a main shaft of the driving motor 15 is in transmission with the feeding steel roller 41 through a belt transmission mechanism 16, the main shaft of the driving motor 15 is in transmission connection with a travelling wheel of the movable seat 7, the travelling wheel travelling speed is consistent with the feeding speed of the feeding steel roller 41, namely the travelling wheel surface travelling speed is consistent with the roller surface travelling speed of the feeding steel roller 41, so that the travelling mechanism and the feeding steel roller 41 can be synchronously carried out.
