[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0028] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0029] In the existing technology, liquid crystal display modules are inevitably subject to the constraints of the spatial environment and the cleanliness of the raw materials, and some dust and foreign matter are inevitably generated during the production process. Foreign matter is divided into two categories based on the material: metal and non-metal. Non-metallic materials mainly include plastic, fiber, polyester, etc. Dust and foreign matter can cause product display failures or defects, affecting the user's visual experience of the product, and therefore require repair or analysis and improvement.

[0030] Currently, repair and analysis usually involve disassembling the defective module and then using simple tools (such as adhesive tape) to stick out the foreign objects. The module is then taken to another location for observation and analysis using a special magnifying glass, and photographed and recorded using a mobile phone. This requires multiple processes and equipment in different locations to complete.

[0031] Existing maintenance analysis tools have the following problems:

[0032] Since adhesive tape is easily left on the surface of the optical film, it will cause the material to be scrapped and the repair efficiency and quality cannot be guaranteed;

[0033] During the maintenance process, it is necessary to collect foreign body samples or image data for later analysis and improvement. Due to the limitations of existing tools, foreign body samples are easily damaged, and the test and analysis data also need to be completed by another device, which cannot guarantee timeliness. Foreign body samples are also easily lost or confused, which is not conducive to systematic cause analysis, statistics and archiving.

[0034] In order to solve the above technical problems, the present application provides a display module maintenance device that can realize the simultaneous sampling and measurement and analysis of foreign matter in the display module, thereby improving maintenance efficiency and quality, while not damaging foreign matter samples, which is conducive to systematic cause analysis, statistics and archiving.

[0035] Figure 1 and Figure 2 A display module maintenance device provided in an embodiment of the present application includes a shell 1, a camera 2, a suction nozzle 3, a fan assembly 4 and a filter assembly 5. The shell 1 has a first end 101 and a second end 102 arranged opposite to each other, and the first end 101 of the shell 1 is provided with a hollow channel 111; the camera 2 is arranged at the second end 102 of the shell 1; the suction nozzle 3 is arranged at the first end 101 of the shell 1, and the suction nozzle 3 has an inlet 31 connected to the hollow channel 111; the fan assembly 4 is arranged in the shell 1, and the air inlet of the fan assembly 4 faces the suction nozzle 3; the filter assembly 5 is arranged in the hollow channel 111 of the shell 1, and the filter assembly 5 is located between the suction nozzle 3 and the fan assembly 4.

[0036] Camera 2 can be an existing industrial camera. Industrial cameras have high image stability, high transmission capacity and high anti-interference ability, and can be used for shooting and size measurement. The camera end of camera 2 is away from the shell 1. It can be understood that the maintenance personnel hold the display module maintenance device and extend the second end 102 of the shell 1 into the interior of the fault display module. Through the camera 2, real-time shooting can be carried out to perform preliminary confirmation of foreign matter, size measurement, and original state photo archiving. The basic form, size, structural appearance, and structural form of the foreign matter are preliminarily measured, observed, and recorded by the camera 2 to determine the source of the foreign matter, thereby providing a basis for improving the control of foreign matter problems and improving product quality. Then, the first end 101 of the shell 1 is extended into the interior of the fault display module, and the fan assembly 4 is turned on, so that the hollow channel 111 inside the shell 1 forms a negative pressure. Foreign matter enters the hollow channel 111 from the inlet 31 of the suction nozzle 3 and is filtered through the filter assembly 5 to achieve the separation of different types of foreign matter samples, thereby facilitating subsequent foreign matter sampling and analysis improvements. Compared with the existing technology, the display module repair device provided in this embodiment can realize the simultaneous sampling and measurement and analysis of foreign matter in the display module, thereby improving the repair efficiency and quality, while not destroying the foreign matter samples, which is conducive to systematic cause analysis, statistics and archiving.

[0037] It should be noted that the housing 1 is cylindrical in shape, and can be a circular cylinder, a square cylinder, or a special-shaped cylinder, without limitation. The fan assembly 4 can be an existing turbofan to increase the air volume.

[0038] In some embodiments, as Figure 3 As shown, the filter assembly 5 includes a filter box 51. A filter screen 52 is provided on the side of the filter box 51 facing the suction nozzle 3, and a first through hole 53 is provided on the other side, which is connected to the air inlet of the fan assembly 4. When the fan assembly 4 is in operation, a negative pressure is formed in the hollow channel 111, and foreign matter is attracted to the filter box 51 from the inlet 31 of the suction nozzle 3. Smaller foreign matter or dust can pass through the filter screen 52, while larger foreign matter is attracted to the filter screen 52. At this point, the preliminary classification of foreign matter samples can be completed.

[0039] Furthermore, the filter cartridge 51 is provided with a first accommodating chamber 54. A magnet 55 is disposed on the inner sidewall of the filter cartridge 51 to attract metallic foreign matter. Smaller metallic foreign matter, after passing through the filter screen 52, is attracted to the sidewall of the filter cartridge 51 by the magnet 55 and stored in the first accommodating chamber 54 for subsequent extraction and classification.

[0040] The filter 52 is configured as an ultra-fine fiber structure with electrostatic adsorption capability, capable of filtering foreign matter with a particle size greater than or equal to 0.3 mm. The filter 52 has an electrostatic adsorption capability, which can effectively absorb particulate foreign matter and prevent it from falling off in a short period of time, making it easier to extract the foreign matter later.

[0041] like Figure 2 As shown, the housing 1 is provided with a second accommodating chamber 121 that communicates with the air outlet of the fan assembly 4. A second through-hole 122 is provided on the housing 1 that communicates with the hollow passage 111. The second through-hole 122 communicates with the external environment to achieve negative pressure operation of the fan assembly 4. Non-metallic foreign matter (such as plastic, fiber, polyester, etc.) continues to pass through the fan assembly 4 under the action of negative pressure and is retained in the second accommodating chamber 121 for subsequent sampling and analysis.

[0042] In some embodiments, as Figure 4 As shown, the housing 1 includes a first barrel 11 and a second barrel 12 that are arranged opposite to each other. The first barrel 11 and the second barrel 12 are detachably connected. The filter assembly 5 is arranged on the first barrel 11, and the fan assembly 4 is arranged on the second barrel 12. By disassembling the first barrel 11, it is convenient to disassemble and clean foreign matter or to sample the foreign matter and analyze it with other precision equipment.

[0043] There are many ways to detachably connect the first barrel 11 and the second barrel 12, and a common threaded connection method can be used. In this embodiment, a threaded connection method is used for description. The end of the first barrel 11 facing the second barrel 12 is provided with a first thread, and the end of the second barrel 12 facing the first barrel 11 is provided with a second thread that matches the first thread. By rotating the first barrel 11, the first barrel 11 and the second barrel 12 can be disassembled and assembled.

[0044] In some embodiments, as Figure 2 As shown, a protective cover 6 is further included, which is arranged at the second end 102 of the housing 1. The protective cover 6 is in a trumpet shape that expands outward in a direction away from the housing 1. By providing the protective cover 6, the camera 2 can be prevented from being damaged by colliding with hard foreign objects.

[0045] The protective cover 6 has a first outer diameter D1 at one end near the camera 2 and a second outer diameter D2 at the other end, with 3 cm ≤ D1 ≤ 3.5 cm and 2 cm ≤ D2 ≤ 2.5 cm. Preferably, D1 is set to 3.5 cm and D2 is set to 2.5 cm to ensure a sufficiently wide field of view for the camera 2. The second outer diameter of the protective cover 6 cannot be too small to prevent it from affecting the normal shooting of the camera 2.

[0046] In some embodiments, the housing 1 further includes a battery 7 and a wireless transmission module 8. The battery 7 and wireless transmission module 8 are disposed within the housing 1 and are electrically connected to the camera 2 and the wireless transmission module 8. Power from the battery 7 provides a reserve and supply of power for the camera 2 and the wireless transmission module 8 within the housing 1. The wireless transmission module 8 enables communication with an external display device, thereby synchronously transmitting video or image data captured by the camera 2 to the external display device via wireless transmission. This can be used to display magnified video and images in real time, facilitating data storage and maintenance analysis, and assisting maintenance personnel in accurately observing and analyzing magnified fault points.

[0047] It should be noted that the inlet 31 of the suction nozzle 3 can be circular, oval, square, or other shapes and can be designed according to the requirements of the operating space. This embodiment is described with the inlet 31 of the suction nozzle 3 being circular. The diameter of the inlet 31 should not be set too large, so as to avoid being unable to operate due to the space limitations of the display module. The diameter of the inlet 31 should not be set too small, resulting in the inability to absorb foreign matter with larger particle sizes. In this embodiment, the inlet 31 of the suction nozzle 3 is circular, and the diameter d of the inlet 31 is set to 0.4 cm-0.6 cm. Preferably, d can be set to 0.5 cm.

[0048] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an", and "" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain", and "have" are inclusive and therefore specify the presence of the stated features, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0049] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0050] The foregoing is merely a detailed description of the present invention, intended to enable those skilled in the art to understand and implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
