Wherein the mold 10 comprises: the diameter of the inner cylinder 12 is equal to that of a printing roller to be provided with an alignment plate; the outer cylinder 11 is sleeved outside the inner cylinder 12 and detachably connected with the inner cylinder 12, the outer cylinder 11 comprises a shading area and a light transmitting area, the shading area or the light transmitting area is provided with an alignment film pattern AA, a cavity 13 is formed between the outer cylinder 11 and the inner cylinder 12, and the cavity 13 is used for accommodating an alignment plate material layer; the ultraviolet light source 20 is used for exposing the alignment plate material layer corresponding to the light-transmitting area of the outer cylinder 11 to form an alignment film pattern AA on the alignment plate material layer.
In the manufacturing apparatus of the alignment plate provided in this embodiment, a cavity 13 for accommodating a material layer of the alignment plate is formed between the outer cylinder 11 and the inner cylinder 12 of the mold 10, the outer cylinder 11 includes a light-shielding region and a light-transmitting region, and the light-shielding region or the light-transmitting region has an alignment film pattern AA, so that the alignment film pattern on the alignment plate can be formed in the cavity 13. Because the diameter of the inner cylinder 12 is equal to the diameter of the printing roller on which the alignment plate is to be arranged, and the alignment film pattern on the alignment plate is formed by adhering to the surface of the inner cylinder 12, the deformation quantity generated by the alignment film pattern when the alignment plate is subsequently fixed on the printing roller is considered in the manufacturing process of the alignment plate, so that the shape and the size of the alignment film pattern of the finally manufactured alignment plate are in accordance with the design requirements when the alignment plate is fixed on the printing roller, the problem that the alignment film formed by transfer printing due to the deformation of the alignment film pattern on the alignment plate is not in accordance with the design requirements is solved, the alignment plate does not need to be manufactured again according to the deformation quantity, the production cost is reduced, and the resources are saved.
In order to improve the uniformity during exposure, the light emitting surface of the ultraviolet light source 20 in this embodiment is preferably a cambered surface, and the light emitting surface of the cambered surface of the ultraviolet light source 10 is curved towards the mold 10, so that the light emitted by the ultraviolet light source 20 can be more uniformly irradiated on the outer cylinder 11 of the mold 10, and the uniformity of exposure of the portion, corresponding to the light transmitting area of the outer cylinder 11, in the alignment material layer is improved. In order to further improve the uniformity in exposure, it is more preferable that the curvature of the light emitting surface of the arc surface of the ultraviolet light source 20 is made equal to the curvature of the outer tube 11.
In this embodiment, the outer cylinder 11 may be made of a metal foil, preferably an aluminum foil, the outer cylinder 11 is made of the metal foil, the outer cylinder 11 with the alignment film pattern can be formed only by engraving the metal foil with laser or performing film pressing on the metal foil for one time, the manufacturing process is simple, and the cost is low.
The outer cylinder 11 may have the following structure: comprises a transparent cylindrical substrate and a shading film arranged on the cylindrical substrate, wherein the area covered by the shading film is the shading area of the outer cylinder 11.

In the manufacturing apparatus of the alignment plate provided in this embodiment, in order to ensure that the inner cylinder 12 has good light transmittance, the material for forming the inner cylinder 12 is preferably quartz.
Since the alignment layer needs to be separated from the mold 10 after the alignment film pattern is formed on the alignment layer, the inner cylinder 12 and the outer cylinder 11 of the mold 10 are required to be detachably connected. The structure for realizing the detachable connection of the two can be various, and the following exemplary modes can be provided: both ends at the inner tube 12 are provided with outer tube fixing grooves, and the notch of the outer tube fixing groove provided at one end of the inner tube 12 is made opposite to the notch of the outer tube fixing groove provided at the other end of the inner tube 12, so that both ends of the outer tube 11 can be inserted into the corresponding outer tube fixing grooves, thereby realizing detachable connection of the outer tube 11 and the inner tube 12.
Example two
Based on the manufacturing apparatus of the alignment plate provided in the first embodiment, the present embodiment provides a manufacturing method of an alignment plate, where the manufacturing method adopts the manufacturing apparatus of the first embodiment to manufacture the alignment plate, and specifically, as shown in fig. 1 and 3, the manufacturing method includes the following steps:
step S1: a layer of alignment material is provided in the cavity 13 of the mold 10.
Step S2: the alignment material layer corresponding to the light-transmitting area of the outer cylinder 11 is exposed by the ultraviolet light source 30.
Step S3: and separating the exposed alignment plate material layer from the mold 10.
Step S4: and removing part of the material of the alignment plate material layer corresponding to the light-transmitting area or the light-shielding area, and forming an alignment film pattern on the alignment plate material layer.
Through the steps S1 to S4, the alignment film pattern on the alignment plate is formed by adhering to the surface of the inner cylinder 12, and since the diameter of the inner cylinder 12 is equal to the diameter of the printing roller on which the alignment plate is to be disposed, the deformation amount generated by the alignment film pattern when the alignment plate is subsequently fixed on the printing roller is considered in the manufacturing process of the alignment plate, so that the shape and the size of the alignment film pattern when the finally manufactured alignment plate is fixed on the printing roller meet the design requirements, the problem that the alignment film formed by transfer printing due to the deformation of the alignment film pattern on the alignment plate does not meet the design requirements is solved, the alignment plate does not need to be manufactured again according to the deformation amount, the production cost is reduced, and resources are saved.
EXAMPLE III
Based on the manufacturing apparatus of the alignment plate provided in the first embodiment, the present embodiment provides a more specific manufacturing apparatus of the alignment plate, which is designed for a case where the alignment plate material layer is formed by a liquid alignment plate material, and specifically: in the foregoing case, the light shielding region 111 of the outer cylinder 11 of the mold 10 has the alignment film pattern AA (see fig. 4); the ultraviolet light emitted by the ultraviolet light source 20 is ultraviolet light capable of curing the liquid alignment plate material, and the wavelength of the ultraviolet light with the characteristic can be 365 nm; as shown in fig. 5, in order to dispose the alignment material layer in the cavity 13 of the mold 10, an injection port 30 and an injection member 40 are added, wherein the injection port 30 is disposed on the outer cylinder 11 of the mold 10 and is communicated with the cavity 13, and the injection member 40 is used for injecting the liquid of the alignment material into the cavity 13 through the injection port 30 to form the alignment material layer.
Since the ultraviolet light emitted by the ultraviolet light source 20 is ultraviolet light capable of curing the liquid alignment material, after the alignment material layer is formed, the portion of the alignment material layer corresponding to the light-transmitting area 112 of the outer barrel 11 is cured under the irradiation of the ultraviolet light, and the portion of the alignment material layer corresponding to the light-shielding area 112 of the outer barrel 11 is not cured and remains in a liquid state, so that the uncured portion can be removed in the subsequent steps. Since the light-shielding region 111 of the outer cylinder 11 has the alignment film pattern AA, the alignment film pattern is formed on the alignment material layer after removing the uncured portion.
By adopting the manufacturing device, the alignment film pattern with the shape and the size meeting the design requirements is formed on the alignment plate, the problem that the alignment film formed by transfer printing does not meet the design requirements due to the deformation of the alignment film pattern on the alignment plate is solved, the alignment plate does not need to be manufactured again according to the deformation, the production cost is reduced, and the resources are saved.
Referring again to fig. 5, in the present embodiment, injection member 40 may include the following components: an injection cylinder 41; the piston 42 comprises a piston rod 421 and a piston head 422 arranged at one end of the piston rod 421, the piston head is arranged in the syringe 41, and the piston head 422 and the syringe 41 can form a closed space; an injection pipe 43 disposed at one end of the syringe 41 and communicating with the closed space; a three-way valve 44 disposed between the injection line 43 and the injection port 30, a first port of the three-way valve 44 being connected to the injection line 43, and a second port of the three-way valve 44 being connected to the injection port 30; a liquid storage part 45 connected with the third port of the three-way valve, wherein the liquid storage part 45 is used for storing liquid of the alignment plate material; a motor 46 connected to the piston rod 421, the motor 46 being adapted to drive the piston 42 in axial movement along the barrel 41.
When the piston 42 moves away from the injection port 30 along the axial direction of the syringe 41, the sealed space becomes large, the internal air pressure decreases, and the first port and the third port of the three-way valve 44 are opened, so that the liquid of the alignment material in the liquid storage part 45 is filled into the sealed space. When the piston 42 moves closer to the injection port 30 along the axial direction of the injection tube 41, the closed space becomes smaller, the internal air pressure increases, and at this time, the first port and the second port of the three-way valve 44 are opened, so that the liquid of the alignment material in the closed space is injected into the cavity 13 of the mold 10 through the injection pipeline 43 and the injection port 30 to form the alignment material layer.
Example four
Based on the manufacturing apparatus of the alignment plate provided in the third embodiment, the present embodiment provides a manufacturing method of an alignment plate, where the manufacturing method adopts the manufacturing apparatus described in the third embodiment to manufacture the alignment plate, and specifically, as shown in fig. 5 and 6, the manufacturing method includes the following steps:
step S1: the liquid of the alignment material is injected into the cavity 13 of the mold 10 by the injection member 40 to form the alignment material layer. When the structure of the injection member 40 is the structure of the injection member 40 shown in fig. 5, the specific process of this step may be: opening the first port and the third port of the three-way valve 44, closing the second port of the three-way valve 44, and driving the piston 42 to move away from the injection port 30 along the axial direction of the injection tube 41 by using the motor 46, so that the liquid of the alignment material in the liquid storage part 45 is filled into the closed space formed by the injection tube 41 and the piston 42; the first port and the second port of the three-way valve 44 are opened, the third port of the three-way valve 44 is closed, the piston 42 is driven by the motor 46 to move close to the injection port 30 along the axial direction of the injection tube 41, and the liquid of the alignment material in the closed space is injected into the cavity 13 of the mold 10 through the injection pipeline 43 and the injection port 30.
Step S2: the alignment plate material layer corresponding to the light-transmitting area of the outer cylinder 11 is exposed by the ultraviolet light source 20, so that the alignment plate material layer corresponding to the light-transmitting area of the outer cylinder 11 is cured. The alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not cured and remains in a liquid state because it is not irradiated by the ultraviolet light.
Step S3: and separating the exposed alignment plate material layer from the mold 10. Since the outer cylinder 11 and the inner cylinder 12 of the mold 10 are detachably connected, when the alignment material layer needs to be separated from the mold 10, the outer cylinder 11 can be detached, and then the alignment material layer is peeled off from the surface of the inner cylinder 12.
Step S4: the material of the alignment layer corresponding to the light-shielding region of the outer cylinder 11 is partially removed by the cleaning solution, and an alignment film pattern is formed on the alignment layer. Since the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not irradiated with ultraviolet light and is not cured, the material of the portion can be removed by the cleaning liquid. Since the light-shielding region of the outer cylinder 11 has the alignment film pattern, the alignment film pattern is formed on the alignment material layer after removing a part of the material of the alignment material layer corresponding to the light-shielding region of the outer cylinder 11. In this step, when the cleaning solution is used to remove the uncured alignment plate material, the cleaning solution can be sprayed out to remove the uncured alignment plate material efficiently and thoroughly.
Through the steps of S1 to S4, the alignment film pattern with the shape and size meeting the design requirements is formed on the alignment plate, so that the problem that the alignment film formed by transfer printing does not meet the design requirements due to deformation of the alignment film pattern on the alignment plate is solved, the alignment plate does not need to be manufactured again according to the deformation, the production cost is reduced, and the resources are saved.
Referring to fig. 6 again, the method for manufacturing an alignment plate provided in this embodiment may further include the following steps:
step S5: the surface of the alignment plate material layer on which the alignment film pattern is formed is cleaned with pure water and alcohol. The cleaning solution remaining on the surface of the alignment plate material layer after the step S4 can be cleaned by this step, and because the cleaning solution is generally corrosive, the cleaning of the remaining cleaning solution can eliminate the corrosive influence of the cleaning solution on the alignment plate material layer.
Step S6: and drying the surface of the cleaned alignment plate material layer by using an air knife.
Step S7: and re-curing the dried alignment plate material layer by using an ultraviolet light source to form the alignment plate. Since the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not cured, and after the partial material of the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is removed, the remaining material of the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not cured, the alignment layer material layer is cured again in this step, the remaining material of the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 can be cured, and the quality of the manufactured alignment plate is improved. Preferably, in the process of curing the alignment material layer again, the alignment material layer may be first soaked in the exposure solution and then cured again by using the ultraviolet light source, which can improve the curing uniformity. If the alignment layer is immersed in the exposure liquid for re-curing, the surface of the formed alignment layer may be preferably blow-dried by an air knife before proceeding to the subsequent step S8.
Step S8: and detecting the surface condition of the formed alignment plate. The surface conditions in the step include the conditions of edge size, surface flatness, surface particles and the like, and by detecting the surface conditions, the alignment plate with unqualified surface conditions can be screened out, so that the quality of the alignment film prepared by using the alignment plate is improved.
EXAMPLE five
Based on the manufacturing apparatus of the alignment plate provided in the first embodiment, referring to fig. 1, the first embodiment provides a more specific manufacturing apparatus of an alignment plate, which is designed for a case where the alignment plate material layer is formed by a colloidal or solid alignment plate material, specifically: in the foregoing case, the light-transmitting region 112 of the outer cylinder 11 of the mold 10 has the alignment film pattern AA (see fig. 7); and the ultraviolet light emitted by the ultraviolet light source 20 is ultraviolet light capable of changing the alignment layer material from a gel or a solid state to a liquid state, and the wavelength of the ultraviolet light having this characteristic may be 245 nm.
Since the ultraviolet light emitted by the ultraviolet light source 20 is ultraviolet light capable of changing the alignment layer material from a gel-like state or a solid state to a liquid state, after the alignment layer material layer is formed, the part of the alignment layer material layer corresponding to the light-transmitting area 112 of the outer cylinder 11 is changed from a gel-like state or a solid state to a liquid state under the irradiation of the ultraviolet light, and the part of the alignment layer material layer corresponding to the light-shielding area 112 of the outer cylinder 11 is still in a gel-like state or a solid state, so that the part changed to a liquid state can be removed in a subsequent step. Since the light-transmitting region 111 of the outer tube 11 has the alignment film pattern AA, the alignment film pattern is formed on the alignment material layer after the liquid portion is removed.

EXAMPLE six
Based on the manufacturing apparatus of the alignment plate provided in the fifth embodiment, the present embodiment provides a manufacturing method of an alignment plate, where the manufacturing method adopts the manufacturing apparatus described in the fifth embodiment to manufacture the alignment plate, and specifically, as shown in fig. 1 and 8, the manufacturing method includes the following steps:
step S1: an alignment layer of a gel-like or solid alignment material is placed in the cavity 13 of the mold 10. The manufacturing process of the alignment plate material layer can be as follows: the liquid alignment plate material is used for forming a coating on a flat surface, and then ultraviolet light is used for irradiating the coating, so that the alignment plate material in the coating is subjected to primary curing from the liquid state and is converted into a colloid or solid state, and a required alignment plate material layer is formed.
Step S2: the ultraviolet light source 20 is used to expose the alignment layer material corresponding to the transparent area of the outer cylinder 11, so that the alignment layer material corresponding to the transparent area of the outer cylinder 11 changes from a gel or a solid state to a liquid state. The alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not irradiated by ultraviolet light, and thus is not changed into a liquid state, and is still in a gel or solid state.
Step S3: and separating the exposed alignment plate material layer from the mold 10. Since the outer cylinder 11 and the inner cylinder 12 of the mold 10 are detachably connected, when the alignment material layer needs to be separated from the mold 10, the outer cylinder 11 can be detached, and then the alignment material layer is peeled off from the surface of the inner cylinder 12.
Step S4: and removing part of the material of the alignment plate material layer corresponding to the light-transmitting area of the outer cylinder 11 by using the cleaning solution to form an alignment film pattern on the alignment plate material layer, wherein the alignment plate material layer with the alignment film pattern is the alignment plate to be manufactured. Since the alignment layer material layer corresponding to the light-shielding region of the outer cylinder 11 is not irradiated with ultraviolet light and does not change to a liquid state, the material of the portion can be removed by the cleaning liquid. Since the light-transmitting area of the outer cylinder 11 has the alignment film pattern, the alignment film pattern is formed on the alignment material layer after removing a part of the material of the alignment material layer corresponding to the light-transmitting area of the outer cylinder 11. In this step, when the cleaning solution is used to remove the liquid alignment plate material, the cleaning solution can be sprayed out to remove the liquid alignment plate material efficiently and thoroughly.
Through the steps of S1 to S4, the alignment film pattern with the shape and size meeting the design requirements is formed on the alignment plate, so that the problem that the alignment film formed by transfer printing does not meet the design requirements due to deformation of the alignment film pattern on the alignment plate is solved, the alignment plate does not need to be manufactured again according to the deformation, the production cost is reduced, and the resources are saved.
Referring to fig. 8 again, the method for manufacturing an alignment plate provided in this embodiment may further include the following steps:
step S5: the surface of the prepared alignment plate was cleaned with pure water and alcohol. The cleaning solution remaining on the surface of the alignment plate material layer after the step S4 can be cleaned by this step, and because the cleaning solution is generally corrosive, the cleaning of the remaining cleaning solution can eliminate the corrosive influence of the cleaning solution on the alignment plate material layer.
Step S6: and drying the surface of the cleaned alignment plate by using an air knife.
Step S7: and detecting the surface condition of the dried alignment plate. The surface conditions in the step include the conditions of edge size, surface flatness, surface particles and the like, and by detecting the surface conditions, the alignment plate with unqualified surface conditions can be screened out, so that the quality of the alignment film prepared by using the alignment plate is improved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
