Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of TV backlight modules, and particularly relates to an attachment jig. Background Art
[0002] With the rapid development of LCD TVs in recent years, TV products are all developing towards the direction of borderless and ultra-narrow border structures. As the carrier base of liquid crystal glass - the metal backplane, there have been major changes in its structure: the "F" structure and the "匚" structure (forming a border groove) of the backplane have become the mainstream trends;
[0003] The general process of installing the extrusion strip on the upper side of the border groove is as follows: cleaning the folded edge of the backplane, tearing off the release paper of the double-sided adhesive of the extrusion strip, assembling the extrusion strip, and pressing the extrusion strip. This process is not only time-consuming at the production end, but also has many problems. For example, first, the extrusion strip is not aligned after attachment, and the straightness is poor; second, the adhesion force is insufficient after pressing the extrusion strip, resulting in detachment.
[0004] Due to insufficient pressing pressure during the bonding between the extrusion strip and the backplane, the bonding is not firm enough. When the backlight module is in use, high temperature will be generated, and under the action of high temperature, the problem that the extrusion strip is prone to detachment is particularly prominent. Summary of the Invention
[0005] The main object of the present invention is to propose an attachment jig, aiming to improve the problem that the pressing force is insufficient during the assembly of the extrusion strip, resulting in the extrusion strip being prone to detachment under the action of high temperature.
[0006] To achieve the above object, the attachment jig proposed by the present invention is used to attach the extrusion strip to an inner sidewall of the border groove of the display device. The attachment jig includes: a main body and an elastic support member; the main body has a first side and a second side in a first direction, and the first side of the main body is used for placing the extrusion strip; and, the elastic support member is disposed on the second side of the main body, and the elastic support member is used to provide an elastic force for the main body in the first direction.
[0007] In one embodiment, a limiting groove extending in a second direction is provided on the first side of the main body, and the limiting groove is used for accommodating the extrusion strip.
[0008] In one embodiment, the main body has a first end and a second end in a third direction, and the first end of the main body is used to extend into the border groove, and the limiting groove is provided adjacent to one end of the main body;
[0009] The limiting groove has a first sidewall and a second sidewall facing in the third direction. The first sidewall is disposed near a first end of the main body. The second sidewall is disposed higher than the first sidewall in a direction outward from the second side of the main body. The portion of the second sidewall protruding from the first sidewall is used to abut against the end of the sidewall of the frame groove.
[0010] In one embodiment, the body has a first end and a second end located in a third direction, the first end of the body being used to extend into the frame groove, and the limiting groove being provided adjacent to one end of the body;
[0011] The limiting groove has a first sidewall and a second sidewall facing upwards. The first sidewall is disposed near a first end of the main body, and the second sidewall is provided with a limiting portion for abutting against an inner sidewall of the frame groove.
[0012] In one embodiment, the second sidewall protrudes in a third direction to form the limiting portion, which extends in a second direction.
[0013] In one embodiment, the first sidewall and the bottom wall of the limiting groove in the first direction are rounded.
[0014] In one embodiment, the body includes:
[0015] A support portion extending along a second direction, with its side in the first direction being a support side, said support side being provided with a side protrusion; and,
[0016] An operating part extends along a third direction, and one end of the operating part is opposite to and spaced apart from the side protrusion in the third direction. The operating part is connected to one end of the bearing part, and the operating part and the side protrusion define the limiting groove.
[0017] In one embodiment, the elastic support is provided as a plurality of elastic support members, which are distributed along a second direction.
[0018] In one embodiment, a mounting post is provided on the second side of the main body;
[0019] The elastic support member includes:
[0020] The support base is slidably fitted onto the mounting post; and,
[0021] A spring is sleeved on the mounting post and abuts against the body and the support base.
[0022] In one embodiment, the attachment fixture further includes a rolling element mounted on the end of the support base away from the body in a first direction.
[0023] In the technical solution of this invention, one side of the main body is used to place the extruded strip, and the other side of the main body is provided with an elastic support. When the attachment fixture is in use, one end of the elastic support abuts against one inner wall of the frame groove. The elastic force of the elastic support is transmitted towards the main body, pushing the main body to move towards the other inner wall of the frame groove, so that the extruded strip adheres to the inner wall of the frame groove. At this time, the elastic support is still in a compressed state, and the elastic support still provides elastic force to the main body. The main body applies pressure to the extruded strip, thereby achieving pressure holding of the extruded strip. A suitable elastic support is selected according to the pressure required for pressure holding. This ensures that the extruded strip receives appropriate pressure during attachment, guaranteeing that the extruded strip can be firmly attached to the frame groove. Attached Figure Description

[0037] Due to the existing installation process of the extruded strips, insufficient pressure is applied during bonding between the extruded strips and the back panel, resulting in a weak bond. This leads to high temperatures generated during backlight module use, making the extruded strips prone to detachment under these conditions. Furthermore, insufficient pressure on the extruded strips in the backlight assembly can damage its functionality: for the backlight assembly, insufficient pressure may affect its ability to seal and protect light. This can lead to light leakage or uneven distribution, thus affecting display brightness and contrast.
[0038] To address the issue of insufficient pressure retention in extruded strips, the following measures can be taken: optimize process parameters by adjusting holding time and pressure to ensure the extruded strip is fully compacted during bonding. Provide a uniform pressure distribution during bonding to avoid localized insufficient pressure retention. These measures can effectively improve the pressure retention effect of the extruded strip in the backlight assembly, thereby enhancing the performance and reliability of the entire backlight module.
[0039] To address the problem of insufficient holding pressure during assembly, which leads to the extruded strips easily detaching under high temperatures, this invention proposes an attachment fixture.
[0040] Please see Figures 1 to 2 In one embodiment of the present invention, the attachment fixture 100 is used to attach the extruded strip 200 to an inner sidewall of the frame groove 300 of the display device. The attachment fixture 100 includes: a main body 1 and an elastic support member 2; the main body 1 has a first side and a second side in a first direction, the first side of the main body 1 is used for placing the extruded strip 200; and the elastic support member 2 is disposed on the second side of the main body, the elastic support member 2 is used to provide elastic force to the main body 1 in the first direction.
[0041] In the technical solution of this invention, one side of the main body 1 is used to place the extruded strip 200, and the other side of the main body 1 is provided with an elastic support 2. When the attachment fixture 100 is in use, one end of the elastic support 2 abuts against one inner wall of the frame groove 300, and the elastic force of the elastic support 2 is transmitted towards the main body 1, pushing the main body 1 to move towards the other inner wall of the frame groove 300, so that the extruded strip 200 is attached to the inner wall of the frame groove 300. At this time, the elastic support 2 is still in a compressed state, and the elastic support 2 still provides elastic force to the main body 1. The main body 1 applies pressure to the extruded strip 200, thereby achieving pressure holding of the extruded strip 200. According to the pressure required for pressure holding, a suitable elastic support 2 is selected. This ensures that the extruded strip 200 is subjected to appropriate pressure during attachment, ensuring that the extruded strip 200 can be firmly attached to the frame groove 300. The elastic support 2 can include various types, such as spring 23 elastic elements, diaphragm elastic elements, and rubber elastic elements. In this design, rubber elastic elements are not selected because they are prone to aging, and the elastic force they can provide will change. In addition, the elastic support 2 only provides elastic force to the main body 1. Whether the elastic support 2 and the main body 1 are fixedly connected is not limited here and will be discussed later.
[0042] Since the extruded strip 200 is elongated, in order to limit the position of the extruded strip 200 when it is placed on the main body 1, it is convenient to attach the extruded strip 200 by operating the attachment jig 100. In one embodiment of the present invention, please refer to... Figure 2 and Figure 3The extruded strip 200 is limited by a limiting groove 11. The first side of the main body 1 has a limiting groove 11 extending in a second direction, which accommodates the extruded strip 200. The limiting groove 11 extends in the second direction, and the extruded strip 200 also extends in the second direction and is placed in the limiting groove 11. The extruded strip 200 and the limiting groove 11 can have an interference fit, a clearance fit, or a clearance fit, but the clearance between them should not be too large. It is worth noting that the length of the limiting groove 11 in the second direction can be greater than or equal to the length of the extruded strip 200, or it can be less than the length of the extruded strip 200, as long as a portion of the extruded strip 200 is installed in the limiting groove 11 and is subject to the limiting effect of the limiting groove 11. In addition, the dimension of the limiting groove 11 in the depth direction must be lower than the height of the extruded strip 200. Otherwise, after the extruded strip 200 is placed in the limiting groove 11, it will be completely located in the limiting groove 11. Under the action of the elastic support 2, the main body 1 will move towards the inner side wall of the frame groove 300, which will only cause the main body 1 to abut against the inner side wall of the frame groove 300. The extruded strip 200 will not be able to abut against the inner side wall of the frame groove 300, resulting in the extruded strip 200 not being able to fit against the inner side wall of the frame groove 300. Therefore, when the extruded strip 200 is installed in the limiting groove 11, it must protrude out of the limiting groove 11. Moreover, after being subjected to the maximum holding pressure and undergoing a certain deformation, there will still be a part protruding out of the limiting groove 11.
[0043] Please see Figure 2When using the attachment fixture 100, the main body 1 does not need to be fully inserted into the frame groove 300. Only the limiting groove 11 portion, along with the extruded strip 200, needs to be inserted into the frame groove 300 to attach the extruded strip 200 to the inner wall of the frame groove 300. The main body 1 also has a portion located outside the frame groove 300. This allows the attachment fixture 100 to be removed from the frame groove 300 after attachment, and the position of the limiting groove 11 can be adjusted during attachment, thereby adjusting the position of the extruded strip 200. Therefore, the main body 1 has a first end and a second end located in the third direction. The first end of the main body 1 is used to extend into the frame groove 300, the limiting groove 11 is located adjacent to one end of the main body 1, and the second end is located outside the frame groove 300 for operation. To ensure the extruded strip 200 is fully installed in the frame groove 300, guaranteeing both aesthetics and a certain degree of straightness, the limiting groove 11 has a first sidewall and a second sidewall facing upwards. The first sidewall is located near the first end of the main body 1, and the second sidewall protrudes beyond the first sidewall in a direction outwards from the second side of the main body 1. The portion of the second sidewall protruding from the first sidewall abuts against the end of the sidewall of the frame groove 300. During use, as the first end of the main body 1 gradually extends into the frame groove 300, the limiting groove 11 also gradually extends into the frame groove 300. When the second sidewall of the limiting groove 11 abuts against the end of the sidewall of the frame groove 300, it cannot extend further. At this point, the limiting groove 11 is completely located within the frame groove 300, so at least the portion of the extruded strip 200 located in the limiting groove 11 is also located within the frame groove 300. This ensures that after attachment, no part of the extruded strip 200 protrudes beyond the frame groove 300.
[0044] Please see Figure 2 and Figure 4The main body 1 is a component used to support the extruded strip 200 and also to transmit the elastic force of the elastic support 2. For the elastic support 2, the direction of deformation is unstable; the elastic force is not necessarily transmitted along the first direction, and there may be an angle between the elastic force direction and the first direction. Furthermore, when operating the main body 1, the plane supporting the extruded strip 200 is not necessarily perpendicular to the first direction; in this case, the main body 1 is tilted. Both of these situations will cause the main body 1 to generate a certain torque, resulting in a larger holding pressure on one side of the extruded strip 200 in the third direction and a smaller holding pressure on the other side. Therefore, the distribution of holding pressure is not uniform, and the overall adhesion effect does not meet the requirements. To prevent the main body 1 from experiencing a certain torque, it is necessary to limit the movement of the main body 1, ensuring that the main body 1 can only move along the first direction, so that the force transmission always occurs along the first direction. Even if there is an angle between the elastic force and the first direction, the components of the elastic force in other directions will be canceled out by the limiting effect. Specifically, when the second sidewall of the limiting groove 11 abuts against the end of the sidewall of the frame groove 300, the first sidewall of the limiting groove 11 also abuts against the third-direction bottom wall of the frame groove 300. At this time, during operation, the attaching fixture 100 only requires the user to apply a force along the third direction towards the first sidewall of the limiting groove 11 to ensure that the first sidewall of the limiting groove 11 abuts against the third-direction bottom wall of the frame groove 300, thus preventing rotation of the main body 1. Furthermore, to prevent deflection of the main body 1, the second sidewall is provided with a limiting part 131, which abuts against an inner sidewall of the frame groove 300. During normal pressure holding, there is a certain gap between the limiting part 131 and the frame groove 300, or they are just touching; there is no force between them. Only when the main body 1 deflects will the limiting part 131 abut against the frame groove 300, thereby limiting the deflection and ensuring the attaching effect. Since the limiting part 131 is located on the second sidewall, there is a clearance fit between the limiting groove 11 and the extruded strip 200. This prevents the limiting part 131 from interfering with the extruded strip 200 in the third direction, thus avoiding deformation of the extruded strip 200. Furthermore, the presence of the limiting part 131 allows the installation position of the extruded strip 200 to be further inward relative to the opening of the frame groove 300. Specifically, the limiting part 131 is formed by protruding from the second sidewall in the third direction, and the limiting part 131 extends along the second direction. Generally, the side of the limiting part 131 furthest from the bottom of the limiting groove 11 in the first direction is perpendicular to the first direction.
[0045] Please see Figure 3 and Figure 4There are generally four grooves 300 on the edge of the backplate, with two dimensions: length and width, both of which are relatively large. Furthermore, the length of the grooves 300 varies for each type of backplate. To improve the versatility of the attachment fixture 100, the main body 1 is designed to be smaller in the second direction, less than the dimension of the grooves 300 in the second direction, allowing the main body 1 to move along the second direction. This enables positional correction and pressure holding of the extruded strip 200 at various points. Based on this design concept, the main body 1 and the extruded strip 200 slide relative to each other along the second direction. Since the main body 1 is used to support the extruded strip 200, friction between the extruded strip 200 and the bottom of the limiting groove 11 is inevitable. To reduce the friction between the main body 1 and the extruded strip 200 and ensure smooth operation when the main body 1 moves along the second direction, it is necessary to prevent the side of the extruded strip 200 from contacting the side of the limiting groove 11. Therefore, a rounded corner is provided between the first sidewall and the bottom wall of the limiting groove 11 in the first direction. Due to the rounded corners, the portion of the extruded strip 200 near the bottom of the limiting groove 11 in the first direction is difficult to approach the first sidewall, thus creating a gap between the extruded strip 200 and the first sidewall. If the side and bottom surfaces of the extruded strip 200 also have rounded corners, then the diameter of the rounded corner between the first sidewall and the bottom wall only needs to be larger than the diameter of the rounded corner between the side and bottom surfaces of the extruded strip 200. Alternatively, the second sidewall and the bottom wall of the limiting groove 11 in the first direction can also be rounded. While rounded corners are possible, the gap between the limiting groove 11 and the extruded strip 200 should not be too large; otherwise, the straightness of the extruded strip 200 during assembly cannot be guaranteed. To reduce friction between the bottom of the limiting groove 11 and the extruded strip 200, a through hole can be provided. One end of the through hole is located at the bottom of the limiting groove 11, and the other end extends outwards along a third direction to the outside of the main body 1. By adding lubricant into the through hole, the friction coefficient between the bottom of the limiting groove 11 and the extruded strip 200 is reduced, thereby reducing friction.
[0046] Please see Figure 4 The specific structure of the main body 1 is as follows: the main body 1 includes a supporting part 12 and an operating part 13; the supporting part 12 extends along a second direction, and its side in the first direction is the supporting side, which is provided with a side protrusion 121; and the operating part 13 extends along a third direction, with one end of the operating part 13 and the side protrusion 121 being opposite to and spaced apart in the third direction, the operating part 13 being connected to one end of the supporting part 12, and the operating part 13 and the side protrusion 121 defining the limiting groove 11. The plane of the supporting part 12 for placing the extruded strip 200 is perpendicular to the first direction. The supporting part 12 needs to be fully inserted into the frame groove 300, while the operating part 13 is located outside the frame groove 300. External force is applied by the multiple operating parts 13 to move the main body 1 along the second direction.
[0047] To ensure sufficient pressure is maintained on the extruded strip 200 during the application process, thereby guaranteeing the installation quality of the extruded strip 200, the required pressure holding pressure was considered. To achieve this, multiple elastic support members 2 were incorporated into the application fixture 100. This design disperses the pressure borne by a single elastic support member 2, thus reducing the performance requirements for each elastic support member 2. This prevents the need for an excessively large elastic force from being provided by a single elastic support member 2, which would be costly and could lead to localized pressure concentration and uneven pressure distribution. To further ensure uniform stress distribution throughout the main body 1, the layout, such as... Figure 1 and Figure 2 As shown, multiple elastic support members 2 are evenly distributed along the second direction. This distribution effectively transmits pressure to all parts of the main body 1, avoiding deformation or damage caused by excessive local stress. Furthermore, this even distribution design also helps improve the stability and repeatability of the application process, thereby ensuring the quality of the extruded strip 200 application. When the size of the elastic support member 2 is smaller than the size of the main body 1 in the third direction, multiple elastic support members 2 can be spaced apart in the third direction. In this way, uniform force distribution can be achieved in the third direction. This has several advantages. First, it ensures uniform force distribution in all parts of the third direction, avoiding insufficient local pressure due to uneven force distribution. Second, by evenly distributing the elastic support members 2 in the third direction, the generation of torque can be effectively avoided, thereby improving the application quality of the extruded strip 200.
[0048] The specific structure of the elastic support 2 is as follows: the elastic support 2 includes a support base 22 and a spring 23. The support base 22 has a rod extending in a first direction. The end of the rod away from the main body 1 extends circumferentially to form a stop. The spring 23 is sleeved on the rod, and the dimension of the spring 23 in the first direction is longer than the dimension of the rod in the first direction. The two ends of the spring 23 in the first direction abut against the stop and the main body 1, respectively. The spring 23 is always in a compressed state. In addition, in order to make the components form a whole and avoid the need to reassemble each component before use, the two ends of the spring 23 in the first direction are fixedly connected to the main body 1 and the stop, respectively. To ensure that the position of the elastic support 2 corresponding to the main body 1 in the third direction remains unchanged (especially when the main body 1 has only one elastic support 2 in the third direction, the elastic support 2 needs to correspond to the center position of the main body 1 in the third direction), a mounting post 21 is provided on the second side of the main body 1; the rod portion is provided with an opening corresponding to the mounting post 21, and the mounting post 21 is at least partially inserted into the opening so that the support seat 22 is slidably sleeved on the mounting post 21. In the structure of the elastic support 2, to further enhance its stability and durability, the material of the support seat 22 is preferably a high-strength engineering plastic or metal material. Such a material selection can ensure that the support seat 22 is not easily deformed or damaged during long-term use, thereby ensuring the overall performance of the attachment fixture. At the same time, the material of the spring 23 should also be selected as a material with high elasticity and fatigue resistance, such as stainless steel or special alloy, to ensure that the spring 23 maintains good elasticity and restoring force during repeated use.
[0049] In another embodiment, the two ends of the spring 23 in the first direction abut against the stop and the main body 1 respectively, but are not fixedly connected to the main body 1 and the stop. The support seat 22 is sleeved on and confined to the mounting post 21, and can slide along the mounting post 21, but cannot detach from the mounting post 21. The support seat 22 itself is detachable. After the support seat 22 is removed, it can be detached from the mounting post 21. At this time, the spring 23 can be replaced, and the support seat 22 can be reassembled after replacing the spring 23. This arrangement allows for the replacement of different springs 23 according to the required pressure holding pressure.
[0050] Since the attachment fixture 100 is to move along the second direction, it also includes a rolling element 3. The rolling element 3 must be able to roll in the second direction, so it can be a ball bearing or a roller. However, when the attachment fixture 100 is in use, the first end of the main body 1 needs to be inserted into or removed from the frame groove 300, and it also needs to roll in a third direction. Therefore, the rolling element 3 is chosen to be a ball bearing, which can roll in multiple different directions to meet the requirements. The rolling element 3 is installed on the end of the support base 22 away from the main body 1 in the first direction and abuts against an inner sidewall of the frame groove 300. Regarding the installation method of the ball bearings, the support base 22 comprises two components distributed along a first direction. The component closer to the main body 1 is the first component, and the component farther from the main body 1 is the second component. The first component has a groove on the side facing the second component in the first direction, where the ball bearing is placed. The ball bearing protrudes from the groove opening plane in a third direction. However, when the mounting fixture 100 is removed from the frame groove 300 after use, the ball bearing, lacking support from the inner side of the frame groove 300, will detach from the groove. Therefore, the second component has a through hole corresponding to the groove position. When the first component and the second component are fixedly connected, the second component upper limit the ball bearing in the first direction, preventing the ball bearing from detaching from the groove. Additionally, the ball bearing protrudes from the end face of the second component through the through hole, but the maximum cross-section of the ball bearing cannot pass through the through hole. Therefore, the ball bearing can roll and cannot detach from the support base 22. The first component can have multiple grooves to accommodate multiple ball bearings, and the second component has correspondingly multiple through holes.
[0051] In the design and application of the attachment fixture 100, for the specific product—the extruded strip 200—the top of the extruded strip 200 in the first direction is designed as a flat plane, which is perpendicular to the first direction. This design aims to ensure that the attachment fixture 100 can obtain the maximum attachment area during use. This design guarantees the stability of the attachment. Furthermore, the bottom of the extruded strip 200 in the first direction adopts a unique design combining two curved surfaces with a flat surface. This design aims to allow the inner curved surface of the extruded strip 200 away from the opening of the frame groove 300 to be better removed from the attachment fixture 100 after installation. This design considers ease of operation and efficiency, ensuring that the attachment fixture 100 can be easily removed from the product after it has completed its function. Simultaneously, the outer curved surface design of the extruded strip 200 near the opening of the frame groove 300 takes into account the requirements of backlighting. The presence of this outer curved surface allows for a more uniform distribution of light when backlit, thereby improving the overall optical effect of the product. Furthermore, this design facilitates the insertion of components such as optical films and diffusers in the backlight assembly, providing convenience for subsequent assembly work. In the design of the extruded strip 200, besides the inner and outer curved surfaces, the saved planar length is also an important consideration. This planar length should not be too small; otherwise, it will be impossible to effectively fix the optical films and diffusers at the bottom of the extruded strip 200. To ensure that these components can be securely mounted on the extruded strip 200, it is generally recommended that this planar length be greater than 3mm. Such design details ensure the overall structural stability of the product and the reliability of assembly.
[0052] The specific method of using the attachment fixture 100 is as follows: 1. Select the inner side of the back plate groove to be processed; 2. Starting from one end of any side, place the extruded strip 200 (adhesive side up) into the limiting groove 11 of the attachment fixture 100; 3. Tear off the double-sided adhesive release paper on the extruded strip 200 (the tearing length exceeds the length of the attachment fixture 100 in the second direction); 4. Insert the compressed fixture into the frame groove 300 of the back plate, and make it in close contact with the inner side of the frame groove 300; 5. While tearing off the double-sided adhesive, move the attachment fixture 100 (keeping the movement direction consistent); 6. Complete the first attachment; 7.
