Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The technical scheme disclosed by each embodiment of the application is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, an embodiment of the present application discloses a coating apparatus for performing a coating operation on a substrate of an optical film. The optical film disclosed herein may be an antireflection film, a protective film, a blue light resistant film, or the like. The disclosed coating apparatus includes a mounting frame 100, a liquid crystal storage tank 200, a driving mechanism 300, a light source 400, and a picture taking device 500.
The mounting frame 100 provides a mounting basis for other component parts of the coating apparatus. The liquid crystal storage tank 200 is configured to store a liquid crystal chemical. The liquid crystal storage tank 200 is provided to the mounting frame 100. The fixed end of the driving mechanism 300 is connected to the mounting frame 100, and the fixed end of the driving mechanism 300 refers to a member for fixedly connecting to the mounting frame 100. Such as the housing, bracket, etc., of the drive mechanism 300. The driving end of the driving mechanism 300 is connected to the light source 400 and the photo taking device 500, and the driving end of the driving mechanism 300 refers to a part for driving the driven object to move. For example, the drive shaft, transmission member, and the like of the drive mechanism 300 are structured.
The driving mechanism 300 may drive the light source 400 and the picture photographing device 500 to extend into the liquid crystal storage tank 200 and move along the axis direction of the liquid crystal storage tank 200. Specifically, the driving mechanism 300 may drive the light source 400 and the picture taking device 500 to extend into the liquid crystal storage tank 200 through the opening of the liquid crystal storage tank 200. The axis direction of the liquid crystal storage tank 200 herein refers to a direction from an opening to a bottom wall of the liquid crystal storage tank 200. Alternatively, the driving mechanism 300 may be a hydraulic cylinder, the fixed end of the driving mechanism 300 may be a cylinder body of the hydraulic cylinder, and the driving end may be a movable rod of the hydraulic cylinder. Alternatively, the driving mechanism 300 may be a driving motor, the fixed end of the driving mechanism 300 may be a housing of the driving motor, and the driving end may be an output shaft of the driving motor. Of course, the driving mechanism 300 may be other power structures, and is not limited herein.
The light source 400 in the present application is used to irradiate the inner side surface of the liquid crystal storage tank 200. The picture photographing device 500 is used for photographing an area irradiated by the light source 400 to obtain a detected picture. An operator can judge whether the liquid crystal storage tank 200 is cleaned or not by detecting the picture. For example, the light source 400 may be a white light source, and the light source 400 irradiates the inner side surface of the liquid crystal storage tank 200, and if the liquid crystal storage tank 200 has a residual liquid crystal chemical on the inner side surface, the residual liquid crystal chemical may have a strong reflectivity to the light of the light source 400, thereby forming a bright light spot. Therefore, if the detected picture shot by the picture shooting device 500 has a strong bright light spot, it is determined that the liquid crystal storage tank 200 is not cleaned. If no bright light spot appears on the detected picture shot by the picture shooter 500, the liquid crystal storage tank 200 is judged to be cleaned. For another example, when a conjugated structure is present in the liquid crystal chemical, the liquid crystal chemical is irradiated with an ultraviolet light source, and the liquid crystal chemical is blue. The light source 400 may be an ultraviolet light source that irradiates the inner side surface of the liquid crystal storage tank 200. If the detected picture photographed by the picture photographing device 500 has blue light spots, it is determined that the liquid crystal storage tank 200 is not cleaned. If the blue light spot does not appear on the detected picture photographed by the picture photographing device 500, it is judged that the liquid crystal storage tank 200 is cleaned. Of course, the determination may be performed in other manners, which will not be described herein.
In a specific detection process, the light source 400 and the image capturing device 500 are driven by the driving mechanism 300 to move to an initial detection position, where the initial detection refers to a position where the image capturing device 500 captures an image for the first time in each detection process, that is, a detection initial position. This initial detection position may be an opening position of the liquid crystal storage tank 200, in which case the driving mechanism 300 drives the light source 400 and the picture camera 500 to move from the opening position to a bottom wall position, where the bottom wall position refers to a bottom position of the liquid crystal storage tank 200. That is, the picture photographing device 500 starts photographing from the opening position, and photographs up to the bottom wall position as the picture photographing device 500 moves. It is also understood that the detection is from top to bottom. Or the initial detection may be the bottom wall position, that is, the driving mechanism 300 moves the light source 400 and the picture photographing device 500 to the bottom of the liquid crystal storage tank 200 first, and then moves from the bottom wall position to the opening position, at which time the picture photographing device 500 starts photographing from the bottom wall position, and along with the movement of the picture photographing device 500, photographs all the way to the opening position. It is also understood that the detection is from bottom to top. The operator determines whether the liquid crystal storage tank 200 is cleaned according to the photographed detection picture.
In the embodiment disclosed by the application, an operator can judge whether the liquid crystal storage tank 200 is cleaned according to the detection picture shot by the picture shooting device 500, so that the liquid crystal liquid medicine can be prevented from remaining on the inner side wall of the cleaned liquid crystal storage tank 200. Therefore, in the coating process, pollution to newly configured liquid crystal liquid medicine is avoided, and the yield of the coating process is improved.
In the above embodiment, the driving mechanism 300 may drive the image capturing device 500 and the light source 400 to continuously move, and at this time, the image capturing device 500 captures images. Alternatively, the driving mechanism 300 may stop at the position for a predetermined time after driving the image capturing device 500 and the light source 400 to move at a certain angle or a certain distance, and the predetermined time may be 1 second, or may be other times. And then shooting the next position, and sequentially cycling until all preset paths are shot. When all the area photographing is completed, the driving mechanism 300 drives the light source 400 and the picture photographing device 500 to protrude out of the liquid crystal storage tank 200.
In order to further improve the detection efficiency, in another alternative embodiment, the coating device further includes a picture processor, the picture processor and the picture taking device 500 may be in communication connection, the detected picture obtained by the picture taking device 500 may be transmitted to the picture processor, and the picture processor is configured to compare the detected picture with the standard picture to obtain picture comparison information, and determine whether the liquid crystal storage tank 200 is cleaned according to the picture comparison information. Here, the standard picture is a picture taken without foreign matters in the liquid crystal storage tank 200, i.e., a picture of the inner surface of the liquid crystal storage tank 200 cleaned. The image processor compares the detected image with the standard image, wherein pixels, image colors and the like can be used as comparison parameters for comparison, so that image comparison information is obtained. Judging whether the liquid crystal storage tank 200 is cleaned or not according to the picture comparison information.
For example, the color of the picture is used as the picture contrast information, the inner surface of the cleaned liquid crystal storage tube is the same color, and when the shot picture generates a bright light spot or a blue light spot, the detected picture and the standard picture have local colors, so that the judgment can be performed through chromatic aberration.
For another example, if the liquid crystal liquid medicine remains on the inner surface of the liquid crystal storage tank 200, the taken picture to be detected has a bright color or color area, and at this time, the pixel unit of the color area on the picture to be compared cannot be matched with the pixel unit of the standard picture, so that it is determined that the liquid crystal storage tank 200 is not cleaned.
According to the above description, no matter what parameter is used as the picture comparison information, when the detection ratio picture has a color area, the color area is different from the standard picture, and the difference is the picture comparison information. This difference may be a contour difference, a line color difference, an arrangement difference of pixel units, and other differences that can distinguish color stripes.
In the embodiment of the application, the picture processor stores or installs corresponding picture comparison algorithm or picture comparison software, and compares the detected picture with the standard picture according to the corresponding picture comparison software so as to obtain picture comparison information. The image comparison software or the image comparison algorithm is a known technology and will not be described in detail herein. Optionally, the image processor may be a processing terminal such as a computer, an upper computer, or the like.
The scheme does not need to distinguish manually, reduces the manual strength, simultaneously avoids the possibility of manual error and improves the detection precision.
In another alternative embodiment, the tank opening of the liquid crystal storage tank 200 may be provided with a first positioning portion 210, the driving end of the driving mechanism 300 may be provided with a second positioning portion 310, and the first positioning portion 210 and the second positioning portion 310 may be in positioning fit to position the light source 400 and the start detection position of the picture taking device 500 extending into the liquid crystal storage tank 200. In this scheme, the first positioning portion 210 and the second positioning portion 310 are used for positioning the initial detection position, so that positioning accuracy is improved, the same position of each detection is ensured, and the problem of detection omission is not easy to occur, so that the reliability of detection is improved.
Alternatively, the first positioning portion 210 may be a first scale line disposed at the opening of the liquid crystal storage tank 200, and the second positioning portion 310 may be a second scale line disposed at the driving end, where when the first scale line is aligned with the second scale line, it is indicated that the light source 400 and the image capturing device 500 are located at the initial detection position. Alternatively, the first positioning portion 210 and the second positioning portion 310 may also contact a switch, which when triggered, indicates that the light source 400 and the picture taking device 500 are located at the start detection position. Of course, the first positioning portion 210 and the second positioning portion 310 may have other structures, which are not limited herein.
In the above embodiment, in order to achieve 360 ° photographing of the inner side wall of the liquid crystal storage tank 200, the number of the picture photographing devices 500 may be plural, and the plurality of picture photographing devices 500 may be arranged in parallel so that the plurality of picture photographing devices 500 may photograph one circumference of the inner side wall. The number of the light sources 400 may be plural, and the plural light sources 400 are arranged in one-to-one correspondence with the plural image cameras 500. Alternatively, in order to reduce the number of the light sources 400, the light sources 400 may be ring-shaped structures, and at this time, the light emitted from the light sources 400 can illuminate a circumference of the inner sidewall of the liquid crystal storage tank 200, so that a plurality of light sources 400 are not required, thereby reducing the number of the light sources 400.
In another embodiment, the driving mechanism 300 may include a first driving source 301, a first connection portion 302, a second driving source 303, and a second connection portion 304, the first driving source 301 being connected with the mounting frame 100. One end of the first connection portion 302 is connected to the driving shaft of the first driving source 301, and the other end of the first connection portion 302 is connected to the second driving source 303. One end of the second connection part 304 is connected to a driving shaft of the second driving source 303, and the other end of the second connection part 304 is connected to the light source 400 and the picture photographing device 500.
The first driving source 301 drives the light source 400 and the picture photographing device 500 to move in the axial direction of the liquid crystal storage tank 200; the second driving source 303 drives the light source 400 and the picture photographing device 500 to rotate around the driving shaft of the second driving source 303.
Specifically, the first driving source 301 drives the second driving source 303, the second connection portion 304, the light source 400, and the picture photographing device 500 to move together along the axis direction of the liquid crystal storage tank 200 through the first connection portion 302, thereby achieving photographing of the picture photographing device 500 from top to bottom or from bottom to top. The second driving source 303 drives the light source 400 and the picture photographing device 500 to rotate around the driving shaft of the second driving source 303 through the second connection part 304, and at this time, the second driving source 303 drives the picture photographing device 500 to achieve circumferential photographing.
In a specific operation process, the first driving source 301 moves the picture photographing device 500 to the first detection position of the liquid crystal storage tank 200 along the axial direction, and then drives the picture photographing device 500 to photograph all circumferential positions of the first detection position through the second driving source 303. Then the first driving source 301 continues to drive the picture photographing device 500 to move to the next detection position in the axial direction, and then photographs the circumferential position of the detection position. Shooting of all detection positions is completed sequentially.
This scheme can further avoid the risk of leakage detection of the inner side wall of the liquid crystal storage tank 200, thereby further improving the reliability of detection.
Alternatively, the first driving source 301 may be a linear motor, and the second driving source 303 may be a servo motor, and of course, the first driving source 301 and the second driving source 303 may be other power structures, which is not limited herein.
In order to reduce the blind detection area, in another alternative embodiment, the coating apparatus may further include an angle adjustment mechanism 600, and the light source 400 and the image capturing device 500 may be rotatably connected to the driving end of the driving mechanism 300 through the angle adjustment mechanism 600, where the angle adjustment mechanism 600 is used to adjust the relative angles of the light source 400 and the image capturing device 500 and the driving end of the driving mechanism 300.
In this scheme, the angle of the light source 400 and the picture photographing device 500 is adjusted by the angle adjusting mechanism 600, so that the detection dead zone in the liquid crystal storage tank 200 can be reduced, and the detection performance is improved. For example, the light source 400 and the picture taker 500 are generally opposite the side walls of the liquid crystal storage tank 200, and the bottom wall of the liquid crystal storage tank 200 is outside the field of view of the light source 400 and the picture taker 500, and thus the bottom wall of the liquid crystal storage tank 200 is generally difficult to detect. In the embodiment of the present application, the light source 400 and the picture photographing device 500 can be adjusted to a position opposite to the bottom wall by the angle adjusting mechanism 600, thereby photographing the bottom wall of the liquid crystal storage tank 200.
Alternatively, the angle adjustment mechanism 600 may employ an electromagnetic adjustment manner, for example, a first electromagnetic member is disposed on an assembly formed by the light source 400 and the image capturing device 500, and a second electromagnetic member is disposed on a driving end. The second electromagnetic member and the first electromagnetic member can generate lorentz force under the condition of being electrified, so that the assembly formed by the light source 400 and the picture photographing device 500 is driven to rotate, and further angle adjustment is realized. Of course, the angle adjusting mechanism 600 may also adopt a mechanical adjusting manner, for example, a motor is disposed on the driving end, and the motor can drive the assembly formed by the light source 400 and the image capturing device 500 to perform angle adjustment.
Here, the angle adjustment mechanism 600 performs a function different from that performed by the second driving source 303 described above, and the second driving source 303 performs a circumferential rotation, but the angle adjustment mechanism 600 performs only a certain angle adjustment, and cannot perform a circumferential rotation.
Further, the angle adjustment mechanism 600 may include a first angle adjustment portion and a second angle adjustment portion, where the light source 400 may be rotatably connected to the driving end of the driving mechanism 300 through the first angle adjustment portion, and the first angle adjustment portion is used for adjusting a relative angle between the light source 400 and the driving end of the driving mechanism 300. The image capturing device 500 may be rotatably connected to the driving end of the driving mechanism 300 through a second angle adjusting portion, and the second angle adjusting portion may be used for adjusting a relative angle between the image capturing device 500 and the driving end of the driving mechanism 300.
In this solution, the relative angles of the light source 400 and the image capturing device 500 are separately adjusted, so as to further improve the flexibility of adjusting the angles of the light source 400 and the image capturing device 500. At the same time, the light source 400 and the picture photographing device 500 can be adjusted to be relatively low, thereby further improving photographing effect.
In another alternative embodiment, the coating apparatus may further include a ranging sensor (not shown) disposed at the driving end of the driving mechanism 300, and the ranging sensor is used to detect the distance between the driving end of the driving mechanism 300 and the bottom wall of the liquid crystal storage tank 200. This scheme can detect the distance between the driving end and the bottom wall of the liquid crystal storage tank 200, thereby avoiding the risk of collision of the light source 400 and the picture taking device 500 with the bottom wall of the liquid crystal storage tank 200.
In the present application, the pictures shot by the picture shooting device 500 can be wirelessly transmitted through bluetooth, and certainly, the pictures can also be transmitted in a wired manner through a line connection, which is not limited herein.
Based on the coating device disclosed in the embodiment of the present application, the embodiment of the present application discloses a detection method, and the disclosed detection method is applied to the coating device as described above, as shown in fig. 4, and the disclosed detection method includes:
s100, the driving mechanism 300 drives the light source 400 and the image capturing device 500 to move to the start detection position.
