Description

Technical Field

[0001] The present invention belongs to the technical field of laminating equipment, and particularly relates to a screen laminating device for display screen assembly. Background Art

[0002] Screen lamination refers to the process of combining a display screen with the front glass panel and touch sensor layer of a device. This process is usually involved in electronic devices with touch screens such as smartphones, tablets, laptops, etc.

[0003] The current screen lamination methods are mainly divided into full lamination and frame lamination. Among them, full lamination is the mainstream lamination method. Full lamination means that the display screen, touch sensor layer, and front glass panel are laminated together over the entire surface. During lamination, it needs to be carried out in a vacuum negative pressure environment, which can ensure the lamination effect to the greatest extent.

[0004] The laminator creates a vacuum negative pressure environment for screen lamination and at the same time uses a pressing action to combine the components of the screen together. However, there is a very crucial bubble removal step in screen lamination. Bubbles are inevitably generated during lamination by the laminator. At this time, a bubble remover is needed to remove the bubbles in the screen. Therefore, in the actual operation process, the operator needs to continuously place the pre-assembled screen into two machine devices, which seriously affects the overall efficiency of lamination. Therefore, a screen lamination device for display screen assembly is proposed to solve the above problems. Summary of the Invention

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, a screen laminating device for assembling a display screen provided by an embodiment of the present invention includes a housing 1, a rectangular installation position is provided on one side of the housing 1, and further includes:

[0031] A combined chamber 2, the combined chamber 2 is located inside the housing 1 and is fixedly arranged in the rectangular installation position. The combined chamber 2 includes a horizontal chamber 201 and a vertical chamber 202. One end of the horizontal chamber 201 is open and this end is fixedly connected in the rectangular installation position. A sealing door 3 is provided at the rectangular installation position outside the housing 1. The vertical chamber 202 is fixedly arranged at one end of the horizontal chamber 201 located inside the housing 1 and is located at the top of the horizontal chamber 201. The inside of the vertical chamber 202 is communicated with the inside of the horizontal chamber 201;

[0032] A carrying assembly 4, the carrying assembly 4 is horizontally arranged in the horizontal chamber 201, and the carrying assembly 4 can move along the length direction of the horizontal chamber 201. A movable plate 402 for receiving a screen assembly is provided on the carrying assembly 4;

[0033] A pressing assembly 5, the pressing assembly 5 includes a first telescopic member 501 vertically and fixedly arranged in the vertical chamber 202. The output end of the first telescopic member 501 is a pressing plate 502 located at the bottom of itself. The first telescopic member 501 is used to drive the pressing plate 502 to move in the vertical direction;

[0034] One side inside the vertical chamber 202 is provided with an air inlet joint 6 and an air outlet joint 7, and the air inlet joint 6 and the air outlet joint 7 are connected to an external air compressor through pipelines.

[0035] In an embodiment of the present invention, the movable plate 402 of the carrying component 4 in the present invention is used to carry the pre-assembled screen component. When the screen component is located in the combination chamber 2, the pressure in the combination chamber 2 is adjusted by an air compressor to create a vacuum negative pressure environment, which can provide sufficient adsorption force to ensure that the screen component does not shift during the fitting process and can effectively reduce air interference. The feature is that the present invention integrates fitting and defoaming together by utilizing the characteristic that there is a pressure value difference between the two steps of fitting and defoaming. On the basis of using the air compressor to change the vacuum pressure environment in the combination chamber 2, low vacuum is used for fitting and then high vacuum is used for defoaming, thus avoiding the operation of frequently taking and placing the screen component and effectively improving the overall efficiency of screen fitting.

[0036] In an example of the present invention, as Figure 1 shown, a control display screen 18 is provided outside the housing 1. A plurality of control buttons 19 are provided on one side of the control display screen 18. Some data during fitting, such as pressure, temperature, etc., can be displayed on the control display screen 18. The process details of fitting can be intuitively expressed through the data, facilitating the operator's control. The control buttons 19 can be used to select the pressure mode, such as switching between the two processes of fitting and defoaming. At the same time, the control buttons 19 can also be used to adjust the specific pressure value. The bottom of the housing 1 is provided with feet 20 for supporting the entire device. It should be noted that the air compressor cannot be integrated into this device and needs to be connected through an external pipeline because the air compressor will vibrate during operation, and this vibration will affect screen fitting.

[0037] As Figure 2 、 Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, guide rails 8 are fixedly connected to both sides inside the horizontal chamber 201. The carrying assembly 4 includes a frame 401 that cooperates with the guide rails 8 on both sides. The movable plate 402 is located inside the frame 401, and when the movable plate 402 moves into the vertical chamber 202, the movable plate 402 can disengage from the frame 401. A handle groove 403 is formed at one end of the frame 401 close to the sealing door 3. An automatic sliding structure 9 is provided on the frame 401. When the frame 401 moves into the horizontal chamber 201, the automatic sliding structure 9 is used to move the movable plate 402 inside the frame 401 towards the inside of the horizontal chamber 201. When the frame 401 moves out of the horizontal chamber 201, the automatic sliding structure 9 is used to move the movable plate 402 inside the frame 401 towards the side of the sealing door 3. When the frame 401 is completely located inside the horizontal chamber 201, the positions of the movable plate 402, the first telescopic member 501 and the pressing plate 502 inside the vertical chamber 202 correspond to each other.

[0038] In one case of this embodiment, when performing screen fitting, first, the sealing door 3 needs to be opened, and then the carrying assembly 4 is pulled out. The pre-assembled screen assembly needs to be placed on the movable plate 402, and then the carrying assembly 4 is pushed into the horizontal chamber 201. Finally, the sealing door 3 is closed to start the fitting work. The carrying assembly 4 can move horizontally and is also convenient for taking and storing the screen assembly. However, due to space limitations, the placement position of the screen assembly needs to be limited. The automatic sliding structure 9 includes three spaced installation through slots 901 formed on both sides of the frame 401. Rollers 902 are rotatably arranged in the installation through slots 901. Slide rods 903 are fixedly connected to both sides inside the frame 401. Positioning slots that cooperate with the slide rods 903 are formed on both sides of the bottom of the movable plate 402. Both sides of the roller 902 are in contact with the side surfaces of the guide rail 8 and the movable plate 402 respectively, and the distance between adjacent two installation through slots 901 is greater than the width of the movable plate 402. After adopting the above structure, the moving range of the movable plate 402 can be greatly increased. For the sake of convenience of explanation, taking Figure 2 the direction as an example, when the screen assembly is placed into the horizontal chamber 201, first, the frame 401 is pulled out. At this time, the roller 902 rotates by itself and pushes the movable plate 402 to move to the right, making it close to the right side. It is more convenient to place the screen assembly on the movable plate 402. For this position state of the screen assembly, after the frame 401 is pushed into the horizontal chamber 201, the rotation direction of the roller 902 is reversed, and the movable plate 402 is pushed to the left side of the frame 401, so that the screen assembly can be pushed to the deepest part of the horizontal chamber 201.

[0039] As Figure 2 、 Figure 4 and Figure 6As shown, as a preferred embodiment of the present invention, a vertically arranged second telescopic member 10 is installed at the bottom of the horizontal chamber 201, and the output end of the second telescopic member 10 is a top plate 11 located at the top of itself, and the positions of the second telescopic member 10, the top plate 11, the first telescopic member 501 and the pressure plate 502 correspond to each other, and a transversely arranged baffle 12 is fixedly connected to the bottom of the vertical chamber 202, and a rectangular opening 13 corresponding to the position of the movable plate 402 is opened on the baffle 12, and the length and width of the rectangular opening 13 are smaller than the movable plate 402, and a sealing gasket 14 is arranged at the upper edge of the movable plate 402, and when the movable plate 402 is located at the top of the top plate 11, the second telescopic member 10 drives the movable plate 402 to move into the vertical chamber 202 through the top plate 11, so that the movable plate 402 contacts the baffle 12.

[0040] In one case of this embodiment, the requirements for vacuum degree in the two steps of laminating and degassing are different. When laminating, the internal spaces of the horizontal chamber 201 and the vertical chamber 202 are interconnected. After the air is evacuated, the specified vacuum degree can be reached. However, if this space is still used for degassing, the time for evacuating air will be greatly increased. After adopting the above structure, after the laminating is completed, the entire combined chamber 2 will not return to the normal pressure state. Under this premise, when the top plate 11 is used to drive the movable plate 402 to move upward, there will be no offset problem between the two. This is mainly due to the fact that in a vacuum environment, various objects can maintain a relatively stable state. At this time, the movable plate 402 will separate from the frame 401 and only move upward. When the movable plate 402 is fitted with the baffle 12, due to the existence of the rectangular opening 13, the screen assembly is located in the vertical chamber 202, and the corresponding space is greatly reduced at this time. It is easier to achieve a degassing vacuum degree in the current state. After the degassing process, the second telescopic member 10 will drive the top plate 11 to fall back into the frame 401, and the movable plate 402 will also resume the coordination with the roller 902.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the first telescopic member 501 and the second telescopic member 10 have the same structure, and two spaced-apart mounting holes are provided on the top of the vertical chamber 202. The first telescopic member 501 includes a telescopic cylinder fixedly arranged in the mounting hole, and the output end of the telescopic cylinder is fixedly connected to a pressure plate 502 through a push rod. The two telescopic cylinders are connected to a gas control assembly through a pipe fitting 16 located at the top of the two telescopic cylinders, and the gas control assembly is arranged on one side of the combined chamber 2 in the shell 1.

[0042] In a case of this embodiment, it should be noted that the gas control component is used to control the air flow direction in the pipe fitting 16, rather than a device for generating suction or transportation. The gas control component can be some control valves and air filtering devices. The telescopic cylinder can also be controlled by an external air compressor pump. The pressing plate 502 is made of a transparent material, such as glass, resin, etc. An image acquisition component 17 is fixedly arranged at the top of the vertical chamber 202. The image acquisition component 17 includes a protection box located between two telescopic cylinders, and a camera device for acquiring images is arranged in the protection box. A plurality of heaters 15 are evenly arranged along the inner wall of the vertical chamber 202. Based on the above-mentioned structural components, as Figure 7 shown, this embodiment also provides a method for controlling the operation of the heater 15. The specific steps include:

[0043] S100, obtain the real-time image captured by the camera device, and segment the real-time image based on the color difference to obtain the characteristic image of the screen component;

[0044] S200, use computer vision technology to identify the bubbles in the characteristic image, and mark the positions of the identified bubbles to obtain a plurality of marked points;

[0045] S300, establish virtual points in the characteristic image based on the positions of the heaters 15, and the virtual points correspond to the individuals of the heaters 15 one by one;

[0046] S400, select the virtual point with the closest distance according to the marked points, and start the corresponding heater 15 based on the selected virtual point.

[0047] It should be noted that the defoaming process generally requires heating because there is an adhesive layer between the glass panel and the screen, and the heated adhesive is beneficial to the discharge of bubbles. Using computer vision technology can identify the positions of bubbles on the screen after fitting. For a single heater 15, the adhesive at the edge of the screen closest to it will be heated first. Therefore, through the above method, the positions of bubbles can be identified, and then the corresponding heaters 15 can be started, which can make the bubble discharge path the shortest and the time-consuming the shortest, thus significantly improving the efficiency of the defoaming process. In addition, the screen component is generally black. To make image segmentation easier, the baffle 12 and the movable plate 402 need to be of other colors, so that the area where the screen component is located can be determined faster.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
