Description

Technical Field

[0001] This utility model relates to the field of display module repair technology, and more specifically, to an auxiliary device for display module repair. Background Technology

[0002] In the production process of industrial display modules, TP film is often used to bond the display frame with double-sided adhesive tape. However, during the bonding process, due to various reasons such as the operating environment and material characteristics, it is difficult to completely avoid the generation of dirt and foreign objects. These adverse factors cause dirt or foreign objects to be clearly visible to the naked eye after some display modules are lit up, thus exceeding the customer's quality standards.

[0003] Traditional rework methods involve heating the TP film-coated display module, placing it film-side down on a hot plate furnace at approximately 60 degrees Celsius for 45 seconds to 1 minute. This softens the double-sided adhesive tape between the TP film and the display module, which is then peeled off, cleaned of dirt or foreign objects, and re-attached. However, this method has a significant problem: if there are foreign objects on the hot plate furnace, the TP film will be affected during heating, causing surface dents and impacting the quality of the reworked product. Therefore, we have proposed an improvement: an auxiliary device for reworking display modules. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that foreign objects on the hot plate furnace platform can cause dents on the surface of the TP film.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A rework auxiliary device for display module includes: a supporting heat-conducting component, wherein a clearance frame is provided in the middle of the supporting heat-conducting component. The supporting heat-conducting component supports the display module, and the clearance frame is used to prevent non-adhesion areas of the TP film, so that a gap is left between the TP film and the hot plate furnace. This application, through the setting of the supporting heat-conducting component and the clearance frame, works together to support the display module, leaving a gap between the TP film of the working module and the hot plate furnace. This reduces the adverse effects of foreign objects on the hot plate furnace platform on the TP film during heating. Furthermore, this application uses the supporting heat-conducting component to heat the double-sided adhesive at the bonding area, allowing for more precise control of the heating position.

[0007] As an improvement of this utility model, the supporting heat-conducting component is also used to transfer the heat of the hot plate furnace to the TP film and double-sided adhesive, so as to heat the double-sided adhesive.

[0008] As an improvement of this utility model, the supporting heat-conducting component is made of aluminum.

[0009] As an improvement of this utility model, the top of the supporting heat-conducting component is provided with several locking blocks, which are used for positioning the display module when it is placed.

[0010] As an improvement of this utility model, the height of the positioning block is lower than the thickness of the single TP film.

[0011] As an improvement of this utility model, each corner of the top of the supporting heat-conducting component is provided with a clearance opening. The clearance opening is located between two adjacent locking blocks. The clearance opening is used to prevent the four corners of the TP film from being exposed to air, reducing the possibility of damage to the four corners of the TP film due to collisions during handling. This significantly reduces the risk of damage to the four corners of the TP film during handling, improves the integrity rate of the TP film, reduces the replacement cost and time waste caused by TP film damage, protects the integrity and performance of the TP film, and ensures the normal display effect and touch function of the display module.

[0012] As an improvement of this utility model, a material inlet is provided at one corner of the outer periphery of the supporting heat-conducting component.

[0013] As an improvement of this utility model, an FPC clearance space is provided between the top of the supporting heat-conducting component and one of the locking blocks. The FPC clearance space is used to prevent the FPC of the display module from being squeezed or damaged during the rework process, which effectively reduces the FPC being squeezed or damaged during the rework process, ensures the electrical performance and signal transmission stability of the FPC, reduces the failure rate of the display module caused by FPC damage, and improves the reliability of the reworked product.

[0014] As an improvement of this utility model, the outer periphery of the supporting heat-conducting component is provided with a number of ventilation ports.

[0015] As an improvement of this utility model, the vent is used to connect the inner and outer spaces of the supporting heat-conducting component, so as to realize the outward dissipation of hot air in the air-proof frame. Because if the vent is not provided, a sealed space is formed between the supporting heat-conducting component, the hot plate furnace and the display module during the heating process, resulting in the accumulation of hot air. By adding several vents, the hot air can be dissipated to the surroundings through the vents, which can reduce the accumulation of hot air.

[0016] Compared with the prior art, the embodiments of this utility model have the following main advantages:

[0017] To address the issue of dents appearing on the TP film surface due to foreign objects on the hot plate furnace platform in existing technologies, this application incorporates a supporting heat-conducting component and a clearance frame. These components work together to support the display module, creating a gap between the TP film of the working module and the hot plate furnace. This reduces the adverse effects of foreign objects on the TP film during heating. Furthermore, this application uses the supporting heat-conducting component to heat the double-sided adhesive at the bonding area, allowing for more precise control of the heating position.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] As described in the background art, the prior art involves placing the laminated display module TP film face down on a hot plate furnace platform at approximately 60 degrees Celsius and heating it for 45 seconds to 1 minute to soften the "U"-shaped double-sided adhesive between the TP film and the display module. Then, the adhesive is peeled off, dirt or foreign objects are cleaned, and the film is re-laminated. However, this method has a significant problem: if there are foreign objects on the hot plate furnace platform, the TP film will be affected by the foreign objects during the heating process, causing dents on its surface, which will affect the quality of the repaired product.

[0027] To solve this technical problem, this utility model provides an auxiliary device for the rework of display module.

[0028] For details, please refer to Figures 1-3 The auxiliary device for repairing display modules specifically includes:

[0029] The heat-conducting support 1 has a clearance frame 102 in the middle. The heat-conducting support 1 is used to support the display module, and the clearance frame 102 is used to clear the non-adhesive part of the TP film so that there is a gap between the TP film and the hot plate furnace.

[0030] The display module repair auxiliary device provided by this utility model, through the setting of the supporting heat-conducting component 1 and the clearance frame 102, can support the display module by working together, so that there is a gap between the TP film of the working module and the hot plate furnace, so as to reduce the adverse effects of foreign objects on the hot plate furnace platform on the TP film during the heating process. In addition, the supporting heat-conducting component 1 is used to conduct heat to heat the double-sided adhesive of the bonding part, which can more accurately control the heating position.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Embodiment 1 of the auxiliary device for repairing display modules of this utility model

[0035] Please refer to Figures 1-3The auxiliary device for rework of display module of this utility model includes: a supporting heat-conducting component 1, and a clearance frame 102 is provided in the middle of the supporting heat-conducting component 1. The supporting heat-conducting component 1 is used to support the display module, and the clearance frame 102 is used to clear the non-bonding position of TP film so that there is a gap between TP film and hot plate furnace, so as to reduce the adverse effects of foreign objects on hot plate furnace platform on TP film during heating. In addition, this application uses the supporting heat-conducting component 1 to conduct heat to heat the double-sided adhesive of the bonding part, which can more accurately control the heating position.

[0036] The design of the clearance frame 102 cleverly creates a physical isolation space between the TP film and the hot plate furnace, reducing the possibility of dust, debris and other foreign objects on the hot plate furnace platform directly contacting the TP film, thereby protecting the integrity of the TP film. The heat-conducting support 1 acts directly on the bonding part, and the heat transfer path is clear, so the heating position can be precisely controlled.

[0037] Furthermore, the heat-conducting support 1 is also used to transfer the heat from the hot plate furnace to the TP film and double-sided adhesive to heat the double-sided adhesive.

[0038] Furthermore, the supporting heat-conducting component 1 is made of aluminum. The size and shape of the supporting heat-conducting component 1 are made according to the size and shape of the display module, and it is commonly a rectangular frame structure. Using aluminum to make the supporting heat-conducting component 1 greatly reduces the production cost, making the display module rework auxiliary device more economically feasible and suitable for large-scale production and application. The rapid heat conduction performance of aluminum allows the heat from the hot plate furnace to be transferred to the TP film and double-sided tape in a short time, improving heating efficiency, shortening the rework cycle, and thus increasing the rework output per unit time. In addition, the lightweight nature of aluminum makes the supporting heat-conducting component 1 easy to operate and transport, reducing the labor intensity of operators and improving the convenience of work.

[0039] Embodiment 2 of the auxiliary device for repairing display modules of this utility model

[0040] Further, this utility model's display module repair auxiliary device, such as... Figures 1-3 As shown, the top of the heat-conducting support 1 is provided with several locking blocks 101, which are used for positioning the display module when it is placed. The setting of the locking blocks 101 greatly improves the accuracy and repeatability of the display module placement, ensures that the placement position is consistent, and reduces human operation error.

[0041] Furthermore, the height of the locking block 101 is lower than the thickness of the individual TP film, which reduces the possibility of the backlight and other components being burned by the heated support heat-conducting component 1 and the locking block 101. This reduces the probability of component damage, improves the integrity rate of components during the repair process, and thus increases the overall yield rate of the reworked display module. It also reduces the additional repair costs and time wasted due to component burns, improving the efficiency and economic benefits of the repair work. At the same time, it protects the performance and quality of the components, ensuring that the reworked display module can work normally and extending the product's lifespan.

[0042] Furthermore, such as Figure 3 As shown, each corner of the top of the heat-conducting support 1 is provided with a clearance opening 106. The clearance opening 106 is located between two adjacent locking blocks 101. The clearance opening 106 is used to avoid the four corners of the TP film from being exposed to air, reducing the possibility of damage to the four corners of the TP film due to collisions during handling. This significantly reduces the risk of damage to the four corners of the TP film during handling, improves the integrity rate of the TP film, reduces the replacement cost and time waste caused by TP film damage, protects the integrity and performance of the TP film, and ensures the normal display effect and touch function of the display module.

[0043] Furthermore, such as Figure 2 As shown, a material inlet 103 is provided at one corner of the outer periphery of the heat-conducting component 1. After heating, use a card to cut a slit in the double-sided tape between the TP film and the display screen, then use your hand to pry it open, clean the dirt and foreign objects, and reassemble it.

[0044] The material inlet 103 is located at the corner of the outer periphery of the supporting heat-conducting component 1, providing an easy cutting position for the card, making it convenient for operators to cut the double-sided tape and then carry out subsequent cleaning and assembly work.

[0045] Furthermore, such as Figure 1 As shown, an FPC clearance space 104 is provided between the top of the supporting heat-conducting component 1 and one of the locking blocks 101. The FPC clearance space 104 is used to prevent the FPC of the display module from being squeezed or damaged during the rework process, ensuring the electrical performance and signal transmission stability of the FPC, reducing the failure rate of the display module caused by FPC damage, and improving the reliability of the reworked product.

[0046] Embodiment 3 of the auxiliary device for repairing display modules of this utility model

[0047] Further, this utility model's display module repair auxiliary device, such as... Figure 1 As shown, a number of air vents 105 are provided through the outer periphery of the heat-conducting support 1.

[0048] Furthermore, such asFigure 1 As shown, the vent 105 is used to connect the inner and outer spaces of the supporting heat-conducting component 1, so as to realize the outward dissipation of hot air inside the vent frame 102. If the vent 105 is not provided, a sealed space is formed between the supporting heat-conducting component 1, the hot plate furnace and the display module during the heating process, which leads to the accumulation of hot air. By adding several vents 105, the hot air can be dissipated to the surroundings through the vents 105, which can reduce the accumulation of hot air.

[0049] For ease of description and understanding, this application uses C to represent the hot plate furnace and D to represent the display module that needs to be repaired. (Refer to...) Figure 4 The cleaned application is placed on a hot plate furnace, which heats the supporting heat-conducting component 1. The TP film of the display module is placed downwards, with the FPC aligned with the FPC clearance 104, and then placed on top of the supporting heat-conducting component 1. Figure 5 As shown, heat it up. After heating, use a card to cut a slit in the double-sided tape between the TP film and the display screen from the material inlet 103. Then, use your hands to pry it open, clean the dirt and foreign objects, and reassemble it to complete the repair.
