Referring to fig. 1 to 6, an embodiment of the present disclosure provides an apparatus for attaching a polarizer 21, which includes a substrate suction stage 10, a polarizer suction stage 20, a negative pressure source 30, and an attaching unit 40.
The substrate adsorption stage 10 is used for adsorbing the glass substrate 11, the polarizer adsorption stage 20 is used for adsorbing the polarizer 21, and the attaching unit 40 is used for attaching the polarizer 21 to the glass substrate 11. The negative pressure source 30 is connected to the polarizer suction stage 20. The negative pressure source 30 is used to make the cavity 201 inside the polarizer adsorption stage 20 form negative pressure, so that the vent holes 203 can achieve an adsorption function, and at the same time, the flow of the gas in the hollowed-out portion 202 can be accelerated. Wherein the negative pressure source 30 may be a vacuum pump.
In an initial state of the polarizer attaching operation, the polarizer 21 has an offset distance D extending out of one end of the polarizer adsorption carrier 20, for example, the offset distance D may be 5mm, and in the initial state, the attaching unit 40 abuts on the polarizer 21 corresponding to the offset distance D. During the polarizer attaching operation, the substrate suction stage 10, the polarizer suction stage 20, and the attaching unit 40 are kept in relative motion, and for example, the substrate suction stage 10 may be moved horizontally from left to right, while the polarizer suction stage 20 and the attaching unit 40 are kept still in the horizontal direction. The attaching unit 40 abuts against the surface of the polarizer 21 and attaches the polarizer to the glass substrate 11 on the substrate suction stage 10 during the movement of the substrate suction stage 10.
The polarizer adsorption carrier 20 has a first surface 22 and a second surface 23 opposite to each other, the polarizer adsorption carrier 20 includes a plurality of hollow portions 202 penetrating through the first surface 22 and the second surface 23, and the polarizer 21 is adsorbed on the first surface 22 and covers a part of the hollow portions 202. The hollow portion 202 is used to form a passage for air to flow, that is, the polarizer 21 does not completely cover the hollow portion 202, especially, the end portion of the polarizer 21 does not completely cover the hollow portion, so as to ensure that the air flow can sufficiently flow between the surfaces of the polarizer adsorption stage 20, that is, the first surface 22 and the second surface 23, and the hollow portion 202. The hollow portion 202 forms an airflow channel, so that gas remaining or generated between the polarizer 21 and the glass substrate 11 can be discharged through the hollow portion 202, thereby reducing the attachment bubbles between the polarizer 21 and the glass substrate 11.
In the embodiment of the present application, the polarizer adsorption stage 20 and the substrate adsorption stage 10 may both be rectangular, or may also be square, circular, or triangular, and the shapes of the polarizer adsorption stage 20 and the substrate adsorption stage 10 may be the same or different, and are not limited specifically herein. Correspondingly, the hollow portion 202 may be rectangular, circular, triangular, may be irregular, and the like, and is not limited herein.
The plurality of hollow portions 202 may be arranged in an array on the polarizer adsorption stage 20. The plurality of hollow portions 202 may be arranged in a plurality of arrays, for example, the hollow portions 202 may be in a shape of a straight line, a cross, a U, a field, a return, a grid, or in other matrix arrangements. Of course, the hollow portions 202 may be distributed concentrically, or may be distributed along a diagonal line of the polarizer suction stage 20.
In the polarizer 21 attaching device in the embodiment of the application, the cavity 201 for forming negative pressure is arranged inside the polarizer adsorption carrier 20, and the plurality of hollow portions 202 penetrating through the first surface 22 and the second surface 23 are arranged on the polarizer adsorption carrier 20, so that the polarizer 21 is adsorbed on the first surface 22 and covers part of the hollow portions 202 during attaching, that is, the end portion of the polarizer 21 does not completely cover the hollow portions 202. Because the hollow part 202 is communicated with the cavity 201, when the negative pressure source 30 vacuumizes the cavity 201 to form negative pressure so that the polarizer adsorption carrying platform 20 realizes the adsorption function of the polarizer 21, the periphery of the hollow part 202 which is not covered by the end part of the polarizer 21 can also flow, namely, the hollow part 202 is used for forming a channel for gas circulation, so that when the polarizer 21 on the polarizer adsorption carrying platform 20 is attached to the glass substrate 11 on the substrate adsorption carrying platform 10 by the attaching unit 40, the gas remained or generated between the polarizer 21 and the glass substrate 11 can be discharged through the hollow part 202, thereby effectively reducing the attaching bubbles between the polarizer 21 and the glass substrate 11, enabling the attachment of the polarizer 21 and the end part of the glass substrate 11 to be smoother, being beneficial to avoiding poor attachment caused by bubbles, improving the processing yield and saving consumables.
In some embodiments, the polarizer adsorption carrier 20 is provided with a plurality of vent holes 203, a plurality of cavities 201 are provided inside the polarizer adsorption carrier 20, and the vent holes 203 are communicated with the cavities 201;
the plurality of hollow-out portions 202 are arranged at intervals along a first direction X and/or a second direction Y respectively, the plurality of cavities 201 extend along the first direction X and/or the second direction Y respectively, the plurality of vent holes 203 are arranged at intervals along the first direction X and/or the second direction Y, and the first direction X and the second direction Y are crossed. Specifically, taking the polarizer suction stage 20 as a rectangle, as shown in fig. 3, the first direction X is a length direction along the polarizer suction stage 20, the second direction Y is a width direction along the polarizer suction stage 20, and the first direction X and the second direction Y are perpendicular to each other.
When the cavities 201 are simultaneously arranged along the first direction X and the second direction Y in a crossing manner, the cavities 201 may be distributed in a cross manner, a field manner, or a grid manner. Of course, the cavities 201 may also be distributed along a diagonal line of the polarizer suction carrier 20, and the like, and are not limited herein. Correspondingly, the plurality of air vents 203 may also be in a cross shape, a field shape or other matrix distribution, and the like, which will not be described herein again. For example, in the plurality of cavities 201, a part of the cavities 201 may extend along the first direction X, another part of the cavities 201 extends along the second direction Y, the adjacent cavities 201 are arranged at intervals, the hollow portion 202 is arranged between the adjacent cavities 201, the cavities 201 respectively extend along the first direction X and the second direction Y in a crossing manner to form a negative pressure channel, and the cavities 201 are communicated with each other, which is beneficial to improving the negative pressure suction efficiency.
In some embodiments, the area of each hollowed-out portion 202 may range from 16mm to 200mm, and the distance between adjacent hollowed-out portions 202 may range from 10mm to 30 mm. Through the diameter with every fretwork portion 202 and the interval setting of fretwork portion 202 in suitable scope, on the basis of guaranteeing the adsorption efficiency of fretwork portion 202, both can improve adsorption efficiency, can guarantee the structural stability of turnover tray again. In addition, different diameters of the hollow portions 202 and different distances between the hollow portions 202 can also play a role in adapting to polarizer adsorption carrying tables 20 with different sizes, so that the polarizer adsorption carrying table 20 can be applied to flexible substrates with different sizes, and the universality of the polarizer adsorption carrying table 20 is improved.
When the area of the polarizer adsorption stage 20 is constant, the larger the area of the hollow portion 202 is, the better the gas flow effect in the hollow portion 202 is, and conversely, the smaller the area of the hollow portion 202 is, the worse the gas flow effect in the hollow portion 202 is. It can be understood that when the area of the hollow portion 202 is too large, the polarizer 21 may form a recess under the action of the hollow portion 202, thereby affecting the yield of the polarizer 21; the air flowing effect of the hollow portion 202 is too small, which may reduce the air discharging effect. Similarly, the distance between the hollow portions 202 represents the distribution density of the hollow portions 202 on the surface of the polarizer adsorption stage 20, and under the same area of the hollow portions 202, if the distance between the plurality of hollow portions 202 is larger, the distribution of the hollow portions 202 on the surface of the polarizer adsorption stage 20 is more sparse, whereas if the distance between the plurality of hollow portions 202 is smaller, the distribution of the hollow portions 202 on the surface of the polarizer adsorption stage 20 is more dense. It can be understood that the more densely the hollowed-out portions 202 are distributed on the surface of the polarizer adsorption carrier 20, the structural strength of the polarizer adsorption carrier 20 may be affected, and the structural stability of the polarizer adsorption carrier 20 is not favorable. The distribution of the hollow portions 202 on the surface of the polarizer adsorption carrier 20 is too sparse, and the adsorption capacity of the hollow portions 202 is too small, which may reduce the adsorption efficiency.
In some embodiments, the polarizer suction stage 20 includes a suction area 205 and a peripheral area 206, and the peripheral area 206 is located at the periphery of the suction area 205. The polarizer 21 is disposed in the absorption region 205, and the hollow portion 202 is partially disposed in the peripheral region 206. The absorption area 205 is used for placing and absorbing the polarizer 21, the hollow portion 202 is partially located in the peripheral area 206, and the peripheral area 206 is provided with the vent hole 203, so that the polarizer 21 is prevented from completely covering the hollow portion 202 and the vent hole 203, the polarizer 21 cannot shield the peripheral area 206, a gas circulation effect is formed between the vent hole 203 and the hollow portion 202, and normal discharge of gas on the surface of the polarizer 21 is ensured.
In some embodiments, the hollow portion 202 is a cross-grid hollow structure, and the polarizer suction stage 20 includes a plurality of connecting ribs 24, and the plurality of connecting ribs 24 cross and enclose to form the hollow portion 202. It can be understood that the inner wall of the connecting rib 24 is also of a hollow structure, and the connecting rib 24 is arranged to form the hollow part 202 in a crossed and enclosed manner, so that the connecting rib 24 can isolate the cavity 201 inside the polarizer adsorption carrier 20, and meanwhile, the connecting rib 24 can also improve the structural strength of the polarizer adsorption carrier 20, which is beneficial to prolonging the service life of the polarizer adsorption carrier 20.

The second air holes 2032 may be formed in one side 25 of the connecting rib 24, or may be formed in both sides 25 of the connecting rib 24.
In some embodiments, the polarizer suction stage 20 has a first end 211 and a second end 212, and the polarizer 21 is attached to the glass substrate 11 along a direction in which the first end 211 points to the second end 212. The first end 211 corresponds to a head end of the polarizer 21, and the second end 212 corresponds to a tail end of the polarizer 21, wherein the head end of the polarizer 21 is a head end of the polarizer 21 first attached to the glass substrate 11 in the attaching process, and the tail end of the polarizer 21 is a tail end of the polarizer 21 finally attached to the glass substrate 11 in the attaching process.
The negative pressure source 30 is located at the second end portion 212, because the second end portion 212 is the end corresponding to the polarizer 21, thereby the negative pressure source 30 adsorbs the gas inside and around the outside of the carrying stage 20 in the process of air suction, thereby the negative pressure source 30 can play a role in guiding the flow direction of the gas, so that the gas flow flows to the second end portion 212 from the first end portion 211, thereby the gas can be better prevented from being removed along the attachment of the polarizer 21, the problem of bubbles between the polarizer 21 and the glass substrate 11 caused by the messy channeling of the gas flow is prevented, and the attachment flatness between the polarizer 21 and the glass substrate 11 is further ensured.
In some embodiments, the polarizer 21 attachment apparatus further includes an air flow guide 50, the air flow guide 50 is spaced apart from the attachment unit 40, and the air flow guide 50 may be disposed near the first end 211 or near the second end 212.

Specifically, the elastic material may be at least one of elastic materials such as silicone, rubber, or polyethylene. Because in the attaching process, the attaching roller 43 is along the second direction Y, vertical direction, produce the effort to the polaroid 21 from bottom to top, consequently, make through adopting elastic material with connecting portion 42, thereby make connecting portion 42 have the deformation space on first direction X, can produce ascending elasticity uniformly, thereby make the attaching roller 43 can closely butt on the polaroid 21, and then make the polaroid 21 closely laminate with glass substrate 11, be favorable to further reducing the bubble between polaroid 21 and the glass substrate 11, be favorable to further improving the laminating yield.

Wherein, the first direction X is a horizontal direction, and the attaching unit 40 reciprocates along the horizontal direction during the attaching process. Because the attaching unit 40 has elasticity because the connecting portion 42 is made of elastic material, the attaching unit 40 reciprocates along the horizontal direction, so that the connecting portion 42 can generate compression elasticity when the attaching unit 40 contacts the polarizer 21 at the initial position, and the attaching unit 40 can be more tightly abutted to the surface of the polarizer, thereby further avoiding the generation of bubbles in the attaching process of the polarizer 21.
