Description

Technical Field

[0001] The invention relates to the field of polaroid patches, and in particular to a polaroid patch device. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizers in front and back tightly attached to the liquid crystal glass to form a liquid crystal film with a total thickness of about 1 mm. In the prior art, the bonding work is often carried out by manually holding a rolling roller for rolling. However, in the process of bonding, the staff must first tear off the protective film on the polarizer to make the adhesive surface of the polarizer appear, and then fix one end of the polarizer on the liquid crystal glass, and then use the rolling method to press the polarizer. However, in this process, one end of the polarizer needs to be aligned with the liquid crystal glass to ensure the bonding effect in the subsequent rolling process. However, manually aligning one end of the polarizer with the liquid crystal glass requires multiple adjustments to ensure smooth bonding, and this operation method is cumbersome. Summary of the invention

[0003] In order to overcome the problem that during the pasting process, the staff must first tear off the protective film on the polarizer to make the adhesive surface of the polarizer visible, and then fix one end of the polarizer on the liquid crystal glass, and then use a roller pressing method to press the polarizer. One end of the polarizer needs to be aligned with the liquid crystal glass, but manually aligning one end of the polarizer with the liquid crystal glass requires multiple adjustments before they can be successfully pasted, which has the disadvantage of cumbersome operation. The present invention provides a polarizer pasting device.

[0029] The conveyor belt 11 is also included. The extrusion roller 4 is fixedly connected with the conveyor belt 11, and the conveyor belt 11 is electrically driven.

[0030] It also includes a first air extraction pipe 12; a cleaning channel 4002 for cleaning dust is opened in the squeezing roller 4, the conveying trough 4001 is connected to the cleaning channel 4002, and the first air extraction pipe 12 is fixedly connected to the squeezing roller 4, and the first air extraction pipe 12 is connected to the cleaning channel 4002.

[0031] The surface of the squeezing roller 4 is coated with a solid lubricant to reduce friction and prevent the polarizer 001 from being damaged.

[0032] Rubber strips are provided at the first air outlet 7001 and the second air outlet 9001 to enhance the bonding effect with the polarizer 001 .

[0033] The upper conveying roller 7 is provided with bristles for cleaning dust on the polarizer 001 so as to facilitate airflow to suck it away.

[0034] The outer surface of the separation roller 9 is provided with a rubber sleeve for tightly fitting the squeezing roller 4 to facilitate the separation of the adsorbed protective film on the second air suction port 9001 .

[0035] First, the staff uses an external vacuum device to connect to the conveying roller 7 and the separation roller 9 respectively, and then uses an external vacuum device to connect to the first vacuum pipe 12. First, the staff places the screen (liquid crystal glass) on the vacuum suction cup 2, then the staff adjusts the position of the screen, aligns one end of the screen with the intersection of the vacuum suction cup 2 and the limit plate 3, and then controls the vacuum suction cup 2 to operate and absorb the screen. Then the staff places the polarizer 001 in the conveying slot 4001, and then controls the first DD motor 8 to drive ... The movable conveying roller 7 rotates clockwise from the perspective of looking from left to right, and the polarizer 001 is conveyed downward by the conveying roller 7, so that the polarizer 001 is conveyed downward along the conveying groove 4001, so that the polarizer 001 contacts the limit plate 3, and then the first DD motor 8 is controlled to stop running, that is, the conveying of the polarizer 001 by the conveying roller 7 is stopped. In the process of conveying the polarizer 001, the built-in sensor of the squeezing roller 4 is used to determine whether the polarizer 001 moves between the first exhaust port 7001 and the second exhaust port 9001. Figure 4It is understood that the sensor is specifically located in the lower area of ​​the surface of the squeezing roller 4 and the axis of the conveying roller 7 below. The sensor can specifically be a light sensor, such as an ambient light sensor. The polarizer 001 will interfere with the ambient light received by the sensor. When the ambient light received by the sensor changes, it means that the end of the polarizer 001 has passed between the first air suction port 7001 and the second air suction port 9001. When the polarizer 001 moves between the first air suction port 7001 and the second air suction port 9001 below, the external air suction device is controlled to operate through the first air suction port 7001 and the second air suction port 9001 to inhale air, that is, in this process, the upper surface of the polarizer 001 is adsorbed through the first air suction port 7001, and the protective film on the polarizer 001 is adsorbed through the second air suction port 9001. Then the second DD motor 10 is controlled to drive the separation roller 9 to rotate, and the separation roller 9 is driven to rotate counterclockwise from the left to the right. At the same time, the first DD motor 8 is controlled to drive the conveying roller 7 9, and the protective film on the polarizer 001 is gradually driven by the separation roller 9, so that the protective film on the polarizer 001 is gradually detached, and when the protective film on the polarizer 001 is separated by the separation roller 9, as the separation roller 9 drives the protective film to rotate, the separation roller 9 is tightly fitted with the squeezing roller 4, that is, the protective film adsorbed on the separation roller 9 is separated from the separation roller 9 under the limiting action of the squeezing roller 4, and the separation roller 9 continues to rotate, and adsorbs the unseparated protective film on the polarizer 001 again, and continues to separate the protective film on the polarizer 001 under the action of the squeezing roller 4 and the separation roller 9, and then the protective film rebounds and contacts with the conveyor belt 11, and at this time, the conveyor belt 11 is controlled to run to drive the protective film to move upward, so that after the subsequent protective film is completely separated from the polarizer 001, the protective film can be automatically discharged without manual processing.

[0036] As the conveying roller 7 rotates to convey the polarizer 001, when the polarizer 001 contacts the limit plate 3, the first DD motor 8 and the second DD motor 10 are controlled to stop driving the conveying roller 7 and the separation roller 9 to rotate, and then the staff controls the electric slider 14 to slide backward on the electric slide rail 13, and the electric slider 14 drives the electric push rod 6 to follow the movement, and at the same time controls the electric push rod 6 to contract and drive the first connecting plate 5 to follow the movement, and the first connecting plate 5 drives the squeezing roller 4 to follow the movement, so that the squeezing roller 4 moves obliquely downward close to the limit plate 3, driving the front end of the polarizer 001 to fit the screen on the vacuum suction cup 2, and the polarizer 001 is pasted in the above manner, which is different from the manual polarizer 001 pasting work, reducing the manual burden, speeding up the pasting efficiency, and ensuring that one end of the polarizer 001 is aligned with one end of the screen without deflection. ; Then, the polarizer 001 is squeezed by the squeezing roller 4 so that the polarizer 001 adheres to the screen, and then the electric push rod 6 is controlled to stop running, but the electric slider 14 keeps sliding backward on the electric slide rail 13. During this process, the second DD motor 10 continues to drive the separation roller 9 to keep separating the protective film on the polarizer 001 at a uniform speed, and at the same time, the first DD motor 8 continues to drive the conveying roller 7 to rotate to keep conveying the polarizer 001 at a uniform speed, thereby realizing automatic film tearing and avoiding the problem in the prior art that when the staff manually tears the film, the polarizer 001 is pulled by the film tearing action, causing the polarizer 001 to deflect, especially the protective film at the initial pasting position. Since the initial position of the polarizer 001 is not firmly bonded, it is easier for the staff to pull the polarizer 001 when tearing the film, causing the overall offset of the polarizer 001, affecting the quality of the polarizer 001 after bonding.

[0037] During the backward movement of the squeezing roller 4, that is, when the polarizer 001 moves along the conveying groove 4001 for bonding, the external dust suction device is controlled to operate, and the dust on the surface of the polarizer 001 is sucked through the cleaning channel 4002 and the first exhaust pipe 12 to avoid the dust on the polarizer 001 from adhering to the outer surface of the squeezing roller 4 during the subsequent bonding process due to the squeezing of the polarizer 001 by the squeezing roller 4, thereby affecting the subsequent bonding work of the polarizer 001, so as to ensure the quality of the subsequent bonding of the polarizer 001.

[0038] Example 2

[0039] On the basis of the above-mentioned embodiment 1, Figure 6-Figure 8 As shown, an adjustment component is also included, which includes a limiting suction cup 102 and a second exhaust pipe 103; the squeezing roller 4 is fixedly connected to the limiting suction cup 102; an air flow channel 4003 is opened on the squeezing roller 4; the squeezing roller 4 is fixedly connected to the second exhaust pipe 103, the air flow channel 4003 is connected to the second exhaust pipe 103, and the air flow channel 4003 is connected to the limiting suction cup 102.

[0040] It also includes an electric shaft 101 ; the mounting frame 1 is rotatably connected to the electric shaft 101 , and the electric shaft 101 is fixedly connected to the vacuum suction cup 2 .

[0041] The limiting suction cup 102 is a rubber structure to avoid scratching the polarizer 001 and enhance the adsorption effect on the polarizer 001 .

[0042] First, the staff uses an external air pump to connect with the second air extraction pipe 103. After the conveying roller 7 drives the polarizer 001 to contact the limit plate 3, the staff controls the external air pump to operate, and absorbs the polarizer 001 through the second air extraction pipe 103, the air flow channel 4003 and the limit suction cup 102, so that the polarizer 001 is close to the limit suction cup 102, that is, in the process of the electric push rod 6, the electric slide rail 13 and the electric slider 14 driving the polarizer 001 to move obliquely downward on the limit plate 3, the limit suction cup 102 supports the polarizer 001. The polarizer 001 is held to prevent the polarizer 001 from being skewed, so that the polarizer 001 is more stable when being attached to the head of the screen. When one end is attached, the air pump of the control device is stopped to stop the operation of the limit suction cup 102, so that the polarizer 001 can move smoothly. When the polarizer 001 is attached to the tail end of the screen, the air pump of the control device is operated again, that is, the tail end of the polarizer 001 is adsorbed by the limit suction cup 102. It should be noted that when the polarizer 001 is pasted to the tail end, When the polarizer 001 is separated from the squeezing roller 4, the tail end of the polarizer 001 will quickly separate from the limit of the squeezing roller 4, that is, the tail end of the polarizer 001 will rub against the edge of the separation roller 9, causing the polarizer 001 to be damaged. The tail end of the polarizer 001 is adsorbed by the limit suction cup 102 to prevent the tail end of the polarizer 001 from quickly separating from the limit of the squeezing roller 4. At the same time, the electric shaft 101 is controlled to drive the vacuum suction cup 2 to rotate counterclockwise from the left to the right, so that the vacuum suction cup 2 is rotated counterclockwise. The suction cup 2 drives the screen adsorbed on it to approach the polarizer 001, further reducing the angle between the screen and the polarizer 001, and then controls the electric push rod 6 to cooperate with the electric slide rail 13 and the electric slider 14 to drive the squeezing roller 4 to move obliquely upward. It should be noted that at this time, the suction force of the vacuum suction cup 2 is relatively small, and its main function is to prevent the polarizer 001 from losing the limit and quickly escaping from the limit of the squeezing roller 4, that is, in the process of oblique upward movement, the polarizer 001 will gradually separate from the vacuum suction cup 2, thereby completing the bonding work of the tail of the polarizer 001.
