Description

Technical Field

[0001] The utility model relates to the technical field of display module production and detection, in particular to a quality inspection device for a sealing frame in display module production. Background Technique

[0002] Liquid crystal display modules are very common in real life. Among them, the sealing frame, as one of the component structures of the liquid crystal display module, plays an important role in the module. After the production of the sealing frame is completed, it is necessary to detect the sealing performance of the sealing frame to ensure the quality of the finished product with the aid of a device.

[0003] When the existing quality inspection device for the sealing frame in liquid crystal display module production is used, first take out the mounting plate from the working box, then set the sealing frame sample on the mounting plate. After fixing, input an appropriate amount of clear water into the working box through the access opening. Then put the mounting plate together with the sealing frame sample into the working box, and make the outer side wall of the sealing frame sample contact with the upper half area of the inner side wall of the working box, and the lower side surface of the mounting plate contact with the clear water. Then control the driving device to drive the pressing plate on the movable rod to move downward to press the mounting plate. Then observe whether the water overflows above the mounting plate. If there is water on the upper surface of the mounting plate, the sealing frame is unqualified. If there is no water on the upper surface of the mounting plate, the sealing frame is qualified.

[0004] The structure of the existing quality inspection device is relatively complex during detection, and the detection is relatively slow, thus affecting the working efficiency when the quality inspection device is used; when the pressing plate of the quality inspection device presses down, it is generally not easy to buffer. If the impact is too large, it is easy to damage the sealing frame of the liquid crystal display module; before the quality inspection device is used, it is necessary to position the sealing frame of the liquid crystal display module. During positioning, the positioning plate is generally driven to move by the cooperation of screws and chutes to clamp and position the sealing frame, which is relatively cumbersome, thus reducing the convenience of the quality inspection device when positioning the sealing frame. Content of the Utility Model

[0005] The purpose of the utility model is to provide a quality inspection device for a sealing frame in display module production, so as to solve the problems of low working efficiency when the quality inspection device is used, easy damage to the sealing frame of the liquid crystal display module, and low convenience when positioning the sealing frame as put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A quality inspection device for a sealing frame in display module production, including a frame, a control key array is installed on the surface of the frame, a quality inspection mechanism is arranged inside the frame, the quality inspection mechanism consists of a quality inspection component and a rubber pad, a buffer mechanism is arranged inside the frame, the buffer mechanism includes a fixed column and a buffer component inside, a positioning mechanism is arranged at the bottom position inside the frame, and the positioning mechanism consists of a positioning component and a clamping block.

[0007] Preferably, a rubber pad is adhered to the bottom position inside the frame, and a quality inspection component is arranged above the rubber pad.

[0008] Preferably, the inside of the quality inspection component includes a sealing pad, a pressing plate, a control valve, a pressure gauge, an electric push rod, and an air inlet pipe. A pressing plate is arranged inside the frame. The pressing plate is slidably matched with the frame. A sealing pad is adhered to the bottom of the pressing plate. An electric push rod is installed at the top position of the frame. The input end of the electric push rod is electrically connected to the output end of the control row key. One end of the electric push rod penetrates through the frame and is fixedly connected to the surface of the pressing plate.

[0009] Preferably, an air inlet pipe is fixed to the surface of the pressing plate, and a control valve and a pressure gauge are installed on the surface of the air inlet pipe.

[0010] Preferably, fixing columns are fixed at the corner positions of the bottom of the frame, and a buffer component is arranged above the fixing columns.

[0011] Preferably, the inside of the buffer component includes a sleeve, a buffer plate, a buffer spring, and a fixing plate. The fixing plates are respectively fixed on both sides of the pressing plate. The fixing plate at the bottom is fixed with a sleeve, and the sleeve is sleeved and matched with the fixing column.

[0012] Preferably, a buffer plate is arranged inside the sleeve. The buffer plate is slidably matched with the sleeve. Buffer springs are fixed on the surface of the buffer plate, and one end of each buffer spring is fixedly connected to the inner wall of the sleeve.

[0013] Preferably, the clamping block is fixed to one side of the fixing column through a support frame. The structure of the clamping block is an L-shaped structure. The surface of the clamping block is in close fit with the surface of the rubber pad. A positioning component is arranged on one side of the clamping block.

[0014] Preferably, the inside of the positioning component includes a positioning block, a fixing stud, and an adjusting screw cylinder. The positioning block is arranged on the surface of the rubber pad. An adjusting screw cylinder is rotatably connected to one side of the positioning block. The fixing stud is fixed to one side of the fixing column, and the fixing stud is in threaded fit with the adjusting screw cylinder.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The quality inspection device for the sealing frame in the production of the display module not only has a simple structure and high working efficiency, making the sealing frame not easily damaged due to excessive impact of the pressing plate during the use of the quality inspection device, but also improves the convenience of positioning the sealing frame by the quality inspection device;

[0016] By setting up a quality inspection mechanism and operating the control row keys, the control row keys are used to control the electric push rod to work. Under the action of the electric push rod, the pressing plate is driven to move downward and cover the surface of the sealing frame, making the sealing gasket closely adhere to the surface of the sealing frame. At this time, the bottom of the sealing frame is closely adhered to the rubber gasket, forming a cavity between the sealing gasket, the pressing plate and the sealing frame. Subsequently, one end of the air pump is hermetically connected to the air inlet pipe, and then gas is introduced into the sealing frame through the air pump. After five minutes of gas introduction, the control valve is closed, and the change in the reading of the pressure gauge is observed. When the reading of the pressure gauge is constant, it indicates that the sealing performance of the sealing frame is qualified. When the reading of the pressure gauge decreases, it indicates that the sealing performance of the sealing frame is unqualified, so as to realize the sealing quality inspection function of the quality inspection device for the sealing frame. The structure is simple and the working efficiency is high;

[0017] By setting up a buffer mechanism, when the pressing plate presses down, the pressing plate drives the buffer component to move downward synchronously, making the sleeve cover the surface of the fixed column and the buffer plate contact the fixed column. When the pressing plate continues to move downward, the fixed plate pushes the sleeve to continue moving downward. At this time, the buffer plate cannot move under the blocking of the fixed column, making the buffer plate slide inside the sleeve and the buffer spring contract. Under the action of the buffer spring, the impact force on the pressing plate is buffered and relieved, reducing the impact of the pressing plate on the sealing frame, so as to realize the buffer function of the quality inspection device, and thus making the sealing frame of the quality inspection device not easily damaged due to excessive impact of the pressing plate during use;

[0018] By setting up a positioning mechanism, the display module sealing frame to be detected is placed inside the clamping block, making both sides of the sealing frame closely adhere to the surface of the clamping block. Subsequently, the adjusting screw cylinder is rotated. Under the thread cooperation of the adjusting screw cylinder and the fixed stud, the positioning block is driven to move on the surface of the rubber gasket, and the positioning block clamps the sealing frame in cooperation with the clamping block to position the sealing frame. When inspecting the sealing frames of the same size later, they can be directly placed between the positioning block and the clamping block, so as to realize the function of the quality inspection device facilitating the positioning of the sealing frame, thereby improving the convenience of the quality inspection device when positioning the sealing frame.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] The structure of a sealing frame quality inspection device for display module production provided by the present invention is as Figure 1 and Figure 2As shown in the figure, it includes a frame 1. A control row of keys 101 is installed on the surface of the frame 1. The model of the control row of keys 101 can be selected from the LA series. A quality inspection mechanism 2 is arranged inside the frame 1. The quality inspection mechanism 2 is composed of a quality inspection component 201 and a rubber pad 202. The rubber pad 202 is adhered to the bottom position inside the frame 1. The quality inspection component 201 is arranged above the rubber pad 202. The inside of the quality inspection component 201 includes a sealing gasket 2011, a pressing plate 2012, a control valve 2013, a pressure gauge 2014, an electric push rod 2015 and an air inlet pipe 2016. The pressing plate 2012 is arranged inside the frame 1. The pressing plate 2012 is slidably matched with the frame 1. The sealing gasket 2011 is adhered to the bottom of the pressing plate 2012. An electric push rod 2015 is installed at the top position of the frame 1. The model of the electric push rod 2015 can be selected from the TA series. The input end of the electric push rod 2015 is electrically connected to the output end of the control row of keys 101. One end of the electric push rod 2015 penetrates through the frame 1 and is fixedly connected to the surface of the pressing plate 2012. The air inlet pipe 2016 is fixed to the surface of the pressing plate 2012. The control valve 2013 is installed on the surface of the air inlet pipe 2016. The pressure gauge 2014 is installed on the surface of the air inlet pipe 2016.

[0026] During use, operate the control row of keys 101 to make the control row of keys 101 control the electric push rod 2015 to work. Under the action of the electric push rod 2015, drive the pressing plate 2012 to move downward and cover the surface of the sealing frame, so that the sealing gasket 2011 is closely attached to the surface of the sealing frame. At this time, the bottom of the sealing frame is closely attached to the rubber pad 202, so that a cavity is formed between the sealing gasket 2011, the pressing plate 2012 and the sealing frame. Then, seal one end of the air pump to the air inlet pipe 2016, and then pass gas into the sealing frame through the air pump. After the gas is passed for five minutes, close the control valve 2013 and observe the change of the reading of the pressure gauge 2014. When the reading of the pressure gauge 2014 is constant, it indicates that the sealing performance of the sealing frame is qualified. When the reading of the pressure gauge 2014 decreases, it indicates that the sealing performance of the sealing frame is unqualified, so as to realize the sealing quality inspection function of the quality inspection device for the sealing frame.

[0027] Furthermore, as Figure 2 and Figure 4As shown in the figure, a buffer mechanism 3 is arranged inside the frame 1. The inside of the buffer mechanism 3 includes a fixed column 301 and a buffer component 302. Fixed columns 301 are fixed at the corner positions at the bottom of the frame 1. A buffer component 302 is arranged above the fixed column 301. Inside the buffer component 302, there are a sleeve 3021, a buffer plate 3022, a buffer spring 3023 and a fixing plate 3024. The fixing plates 3024 are respectively fixed on both sides of the pressing plate 2012. A sleeve 3021 is fixed at the bottom of the fixing plate 3024. The sleeve 3021 is sleeved and matched with the fixed column 301. A buffer plate 3022 is arranged inside the sleeve 3021. The buffer plate 3022 is slidably matched with the sleeve 3021. Buffer springs 3023 are fixed on the surface of the buffer plate 3022. One end of the buffer spring 3023 is fixedly connected to the inner wall of the sleeve 3021.

[0028] During use, when the pressing plate 2012 is pressed down, the pressing plate 2012 drives the buffer component 302 to move downward synchronously, so that the sleeve 3021 is sleeved on the surface of the fixed column 301, and the buffer plate 3022 contacts the fixed column 301. When the pressing plate 2012 continues to move downward, the fixing plate 3024 pushes the sleeve 3021 to continue to move downward. At this time, the buffer plate 3022 cannot move under the blocking of the fixed column 301, so that the buffer plate 3022 slides inside the sleeve 3021, causing the buffer spring 3023 to contract. Under the action of the buffer spring 3023, the pressing plate 2012 is buffered and unloaded, reducing the impact of the pressing plate 2012 on the sealing frame, so as to realize the buffer function of the quality inspection device.

[0029] Furthermore, as Figure 2 and Figure 3 shown, a positioning mechanism 4 is arranged at the bottom position inside the frame 1. The positioning mechanism 4 is composed of a positioning component 401 and a clamping block 402. The clamping block 402 is fixed on one side of the fixed column 301 through a support frame. The structure of the clamping block 402 is an L-shaped structure. The surface of the clamping block 402 is closely attached to the surface of the rubber pad 202. A positioning component 401 is arranged on one side of the clamping block 402. The inside of the positioning component 401 includes a positioning block 4011, a fixed stud 4012 and an adjusting screw cylinder 4013. The positioning block 4011 is arranged on the surface of the rubber pad 202. An adjusting screw cylinder 4013 is rotatably connected to one side of the positioning block 4011. The fixed stud 4012 is fixed on one side of the fixed column 301. The fixed stud 4012 is threadedly matched with the adjusting screw cylinder 4013.

[0030] During use, place the display module sealing frame to be detected inside the clamping block 402, making both sides of the sealing frame closely adhere to the surface of the clamping block 402. Subsequently, rotate the adjusting screw cylinder 4013. Under the screw thread fit between the adjusting screw cylinder 4013 and the fixed stud 4012, drive the positioning block 4011 to move on the surface of the rubber pad 202, so that the positioning block 4011 clamps the sealing frame in cooperation with the clamping block 402, positioning the sealing frame, enabling the subsequent sealing frames of the same size to be directly placed between the positioning block 4011 and the clamping block 402 during quality inspection, thereby realizing the function that the quality inspection device is convenient for positioning the sealing frame.

[0031] Working principle: During use, first place the display module sealing frame to be detected inside the clamping block 402, making both sides of the sealing frame closely adhere to the surface of the clamping block 402. Subsequently, rotate the adjusting screw cylinder 4013. Under the screw thread fit between the adjusting screw cylinder 4013 and the fixed stud 4012, drive the positioning block 4011 to move on the surface of the rubber pad 202, so that the positioning block 4011 clamps the sealing frame in cooperation with the clamping block 402, positioning the sealing frame, enabling the subsequent sealing frames of the same size to be directly placed between the positioning block 4011 and the clamping block 402 during quality inspection, thereby realizing the function that the quality inspection device is convenient for positioning the sealing frame, thus improving the convenience of the quality inspection device when positioning the sealing frame.

[0032] Subsequently, operate the control row keys 101 to make the control row keys 101 control the operation of the electric push rod 2015. Under the action of the electric push rod 2015, drive the pressing plate 2012 to move downward and cover the surface of the sealing frame, making the sealing gasket 2011 closely adhere to the surface of the sealing frame. At this time, the bottom of the sealing frame closely adheres to the rubber pad 202, forming a cavity between the sealing gasket 2011, the pressing plate 2012 and the sealing frame. Subsequently, seal one end of the air pump to the air inlet pipe 2016, and then introduce gas into the sealing frame through the air pump. After the gas is introduced for five minutes, close the control valve 2013 and observe the change in the reading of the pressure gauge 2014. When the reading of the pressure gauge 2014 is constant, it indicates that the sealing performance of the sealing frame is qualified. When the reading of the pressure gauge 2014 decreases, it indicates that the sealing performance of the sealing frame is unqualified, thereby realizing the function of the quality inspection device for sealing quality inspection of the sealing frame, with a simple structure and high working efficiency.

[0033] Meanwhile, when the pressing plate 2012 presses downwards, the pressing plate 2012 drives the buffer component 302 to move downwards synchronously, so that the sleeve 3021 is sleeved on the surface of the fixed column 301, and the buffer plate 3022 contacts the fixed column 301. When the pressing plate 2012 continues to move downwards, the fixing plate 3024 pushes the sleeve 3021 to continue moving downwards. At this time, the buffer plate 3022 cannot move under the blocking of the fixed column 301, so that the buffer plate 3022 slides inside the sleeve 3021, causing the buffer spring 3023 to contract. Under the action of the buffer spring 3023, the pressing plate 2012 is buffered and unloaded, reducing the impact of the pressing plate 2012 on the sealing frame, so as to realize the buffer function of the quality inspection device, thereby making it difficult for the sealing frame to be damaged due to excessive impact of the pressing plate 2012 when the quality inspection device is in use, and finally completing the use work of the quality inspection device.
