Description

Technical Field

[0001] The utility model relates to the technical field of display processing equipment, in particular to a composite device for a glass substrate and a polarizing plate. Background Art

[0002] A liquid crystal substrate and a polarizer are the main components of a liquid crystal display. The polarizer is a dichroic transparent film that allows light vibrations parallel to the light transmission axis direction to pass through, while light perpendicular to this direction is absorbed. This phenomenon is called light polarization. After attaching the liquid crystal substrate to the polarizer, it can filter out some polarized light transmitted by the non-powered liquid crystal, enabling the image of the liquid crystal display to be recognized by the human eye. Usually, the liquid crystal substrate and the polarizer are attached with glue. Currently, when compounding a glass substrate and a polarizing plate, in order to improve the pressing degree between the two, a composite device for the glass substrate and the polarizing plate is used to compact between the glass substrate and the polarizing plate to avoid the situation where the peripheral end faces of the polarizing plate and the liquid crystal substrate open and close.

[0003] However, when compounding a glass substrate and a polarizing plate, when static electricity and dust adhere to the surface of the glass substrate, there may be certain gaps and bubbles in the attachment of the polarizing plate, affecting the quality of the film coating. Currently, the cleaning of static electricity and dust on the surface of the glass substrate is manually wiped by workers, and the cleaning efficiency is low, thereby reducing the compounding efficiency of the glass substrate and the polarizing plate;

[0004] In summary, currently, a composite device for a glass substrate and a polarizing plate that can improve the compounding efficiency and safety is needed. Summary of the Utility Model

[0026] Embodiment 1

[0027] To solve the technical problems in the background art, the following glass substrate and polarizer laminating device is provided:

[0028] Combined Figures 1 - 6 As shown, the glass substrate and polarizer laminating device provided by the present utility model includes a bottom plate 1, a vertical plate 2 is fixedly installed on the bottom plate 1, two horizontally arranged rotating shafts 3 are rotatably installed on the vertical plate 2, and the two rotating shafts 3 are located in the same vertical plane. A polarizer roll 4 is detachably installed on the rotating shaft 3. A compaction mechanism 5 for compacting the glass substrate and the polarizer is installed on the vertical plate 2 and on the same side of the two rotating shafts 3. A cleaning mechanism 6 for cleaning the surface dust of the glass substrate is installed on the bottom plate 1 and on the side of the rotating shaft 3 away from the compaction mechanism 5. Specifically, it should be noted that: the opposite side of the cleaning mechanism 6 and the vertical plate 2 is externally connected with a spraying machine for spraying glue on the glass substrate; a guiding mechanism 12 for guiding the glass substrate is installed on the bottom plate 1 and on the opposite side of the vertical plate 2 and the bracket 601.

[0029] When laminating the glass substrate and the polarizer, the glass substrate is moved along the cleaning mechanism 6 towards the compaction mechanism 5. When one end of the glass substrate moves to the side of the cleaning mechanism 6 close to the vertical plate 2, the spraying machine sprays glue on the glass substrate. When one end of the glass substrate moves to one side of the two rotating shafts 3, the polarizer plates on the two polarizer rolls 4 are respectively attached to the two ends of the glass on both sides of the glass substrate. When the glass substrate continuously moves towards the compaction mechanism 5, the compaction mechanism 5 can compact between the glass substrate and the polarizer. By setting the cleaning mechanism 6, when laminating the glass substrate and the polarizer, when there is static electricity and dust attached to the surface of the glass substrate, the cleaning mechanism 6 cleans the static electricity and dust attached to the surface of the glass substrate, replacing the way that workers manually wipe and clean the static electricity and dust on the surface of the glass substrate. The cleaning efficiency is high, thus improving the laminating efficiency of the glass substrate and the polarizer.

[0030] By setting the guiding mechanism 12, when laminating the glass substrate and the polarizer, it is convenient to guide the movement of the glass substrate, thus facilitating the use by workers, and further improving the laminating efficiency of the glass substrate and the polarizer.

[0031] Embodiment Two

[0032] As Figure 1 、 Figure 4 and Figure 6 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0033] In this embodiment, the cleaning mechanism 6 includes a bracket 601 fixedly mounted on the base plate 1, and two cleaning cotton rollers 602 are mounted on the bracket 601 to rotate horizontally, and the two cleaning cotton rollers 602 are located on the same vertical plane. Specifically, when the glass substrate passes through the opposite sides of the two cleaning cotton rollers 602, the two cleaning cotton rollers 602 are in contact with the glass substrate, and a motor 603 is fixedly mounted on the bracket 601, and the output shaft of the motor 603 is coaxially fixedly connected to one of the cleaning cotton rollers 602, and the two cleaning cotton rollers 602 are connected by a spur gear assembly 604. Specifically, the spur gear assembly 604 includes two mutually meshing spur gears, and the two spur gears are coaxially fixedly connected to the two cleaning cotton rollers 602, respectively.

[0034] When in use, one end of the glass substrate is located at the opposite side of the two cleaning cotton rollers 602. When the glass substrate is moved toward the compacting mechanism 5, the motor 603 is controlled to be turned on, and the output shaft of the motor 603 rotates, thereby driving one of the cleaning cotton rollers 602 to rotate, and then the other cleaning cotton roller 602 can be driven to rotate through the spur gear assembly 604, so that the dust and static electricity attached to the surface of the glass substrate can be cleaned.

[0035] In this embodiment, the compacting mechanism 5 includes a fixed plate 501 symmetrically installed on the vertical plate 2, and the opposite sides of the two fixed plates 501 are hinged with a fixed frame 502 through a hinge shaft, and a compacting roller 503 is rotatably installed on the fixed frame 502. A driving member 504 acting on the fixed frame 502 is installed on the fixed plate 501, which is used to rotate the fixed frame 502 on the fixed plate 501 so that the two compacting rollers 503 are in contact with each other. Specifically, it should be noted that in this embodiment, the driving member 504 is a torsion spring, which is sleeved on the outside of the hinge shaft, and the two ends of the torsion spring are respectively in contact with the fixed plate 501 and the fixed frame 502.

[0036] When in use, the polarizer plates on the two polarizer rolls 4 are made to fit with the ends of the glass on both sides of the glass substrate respectively. When the glass substrate continues to move toward the compacting mechanism 5, the glass substrate and the polarizer plate are located on opposite sides of the two compacting rollers 503, and the two compacting rollers 503 form a conflict with the polarizer plates on both sides of the glass substrate. As the position of the glass substrate continues to move, the two fixing frames 502 rotate on the two fixing plates 501 respectively, so that the free ends of the two fixing frames 502 move away from each other, the torsion spring is deformed, and the two compacting rollers 503 rotate on the two fixing frames 502 respectively, so as to realize compaction between the glass substrate and the polarizer.

[0037] Embodiment 3

[0038] like Figures 1 - 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0039] In this embodiment, a cavity 7 is formed inside the cleaning cotton roller 602. A plurality of air outlet holes 8 are formed in the outer side wall of the cleaning cotton roller 602, and all of them are communicated with the cavity 7. One end of the cleaning cotton roller 602 is provided with a connecting pipe 9 communicated with the cavity 7. A plasma fan 10 is fixedly installed on the bottom plate 1. The air outlet end of the plasma fan 10 is provided with a ventilation pipe. The connecting pipe 9 is communicated with the ventilation pipe through a rotary joint 11. Among them, the plasma fan 10 and the motor 603 are both powered by an external power supply.

[0040] By using the plasma fan 10 and the air outlet holes 8, during use, the plasma fan 10 is controlled to start. The plasma fan 10 blows the plasma air into the cavity 7 through the ventilation pipe and then discharges it through the air outlet holes 8. Thus, when the two cleaning cotton rollers 602 rotate to clean the dust and static electricity attached to the surface of the glass substrate, the plasma air blown by the plasma fan 10 is blown onto the surface of the glass substrate, thereby further improving the cleaning effect of the dust and static electricity attached to the surface of the glass substrate.

[0041] In this embodiment, the guiding mechanism 12 includes two guiding plates 1201 both slidably installed on the bottom plate 1. Opposite sides of the two guiding plates 1201 are symmetrically provided with guiding grooves 1202. A bidirectional threaded rod 1203 is rotatably installed on the bottom plate 1, and the bidirectional threaded rod 1203 is threadedly connected to both guiding plates 1201.

[0042] During use, according to the width dimension of the glass substrate, the bidirectional threaded rod 1203 is rotated to make the two guiding plates 1201 move in opposite directions, and the distance between the two guiding grooves 1202 is adjusted so that the distance between the inner side walls of the two guiding grooves 1202 matches the width dimension of the glass substrate. When the glass substrate and the polarizer are laminated, the glass substrate is passed through the two guiding grooves 1202, thereby realizing the guiding of the movement of the glass substrate.

[0043] In this embodiment, limiting plates 13 are installed on the opposite sides of the two guiding plates 1201. Among them, the limiting plate 13 far from the vertical plate 2 is rotatably installed on the guiding plate 1201, and one end of the limiting plate 13 far from the guiding plate 1201 movably penetrates through the two rotating shafts 3. When the two sides of the glass substrate are respectively in contact with the inner side walls of the two guiding grooves 1202, the two limiting plates 13 are respectively in contact with the two sides of the polarizer roll 4. It should be noted that when the two guiding plates 1201 slide on the bottom plate 1 to make the distance between the two guiding plates 1201 the largest, the limiting plate 13 far from the vertical plate 2 is located outside the rotating shaft 3, and the limiting plate 13 is rotated on the guiding plate 1201, so that the polarizer roll 4 on the rotating shaft 3 can be disassembled and replaced; a guiding roller 14 is rotatably installed on the fixing plate 501 and close to one side of the rotating shaft 3.

[0044] With the design of the two limit plates 13, when guiding the glass substrate through the two guiding plates 1201, the two limit plates 13 are respectively attached to both sides of the polarizer roll 4, achieving the effect of limiting the polarizer roll 4 on the rotating shaft 3, which facilitates fixing the position of the polarizer roll 4 on the rotating shaft 3;

[0045] By setting the guiding rollers 14, during use, the two compaction rollers 503 are in contact with the polarizer plates on both sides of the glass substrate. When compacting between the glass substrate and the polarizer plate, the two guiding rollers 14 respectively guide the two polarizer plates, increasing the curvature of the polarizer plate between the compaction roller 503 and the polarizer roll 4, and improving the protection effect on the polarizer plate when the glass substrate and the polarizer are laminated.

[0046] The working principle and usage process of the present utility model are as follows:

[0047] When laminating the glass substrate and the polarizer:

[0048] According to the width dimension of the glass substrate, the polarizer roll 4 matching the width dimension of the glass substrate is sleeved outside the rotating shaft 3, enabling the limit plate 13 to rotate on the guiding plate 1201, so that the limit plate 13 can penetrate through the two rotating shafts 3. Rotate the bidirectional threaded rod 1203 to make the distance between the inner side walls of the two guiding grooves 1202 match the width dimension of the glass substrate, and limit the polarizer roll 4 through the two limit plates 13. Then, place the end of the glass substrate on the opposite sides of the two cleaning cotton rollers 602. Control the motor 603 and the plasma fan 10 to start. When the motor 603 drives the two cleaning cotton rollers 602 to rotate to clean the dust and static electricity attached to the surface of the glass substrate, the plasma fan 10 blows the plasma through the ventilation pipe into the cavity 7 and then discharges it through the air outlet 8 to further clean the dust and static electricity attached to the surface of the glass substrate. When the glass substrate moves towards the compaction roller 503, the spraying machine sprays glue on the glass substrate. When one end of the glass substrate moves to one side of the two rotating shafts 3, the polarizer plates on the two polarizer rolls 4 are respectively attached to the glass ends on both sides of the glass substrate. When the glass substrate continuously moves towards the compaction mechanism 5, the guiding roller 14 guides the polarizer plate. The glass substrate and the polarizer plate are located on the opposite sides of the two compaction rollers 503, and the two compaction rollers 503 are in contact with the polarizer plates on both sides of the glass substrate, and the two compaction rollers 503 respectively rotate on the two fixing frames 502 to achieve compaction between the glass substrate and the polarizer;

[0049] When it is necessary to disassemble and replace the polarizer roll 4:

[0050] Rotate the bidirectional threaded rod 1203 to move the two guide plates 1201 in opposite directions, so that the distance between the two guide plates 1201 is maximized. The limiting plate 13 away from the vertical plate 2 is located outside the rotating shaft 3. Rotate the limiting plate 13 on the guide plate 1201 so that the limiting plate 13 does not contact the two rotating shafts 3, and then the polarizer roll 4 on the rotating shaft 3 can be disassembled and replaced.
