Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of TV backlight modules, and particularly to an attaching fixture. 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 bearing foundation of the LCD 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: backplane hemming and cleaning, tearing off the release paper of the double-sided tape of the extrusion strip, assembling the extrusion strip, and pressing the extrusion strip. This process not only takes time in production, 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 easily detached is particularly prominent. Summary of the Invention
[0005] The main object of the present invention is to propose an attaching fixture, aiming to improve the problem that the pressing force is insufficient during the assembly of the extrusion strip, resulting in the extrusion strip being easily detached under the action of high temperature.
[0006] To achieve the above object, the attaching fixture proposed by the present invention is used to attach the extrusion strip to an inner side wall of the border groove of the display device. The attaching fixture 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 arranged 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 an embodiment, a limiting groove extending in a second direction is arranged on the first side of the main body, and the limiting groove is used for accommodating the extrusion strip.

[0009] The limiting groove has a first side wall and a second side wall in a third direction, wherein the first side wall is arranged close to the first end of the main body, wherein the second side wall is arranged higher than the first side wall in the direction from the second side of the main body and outward, and the part of the second side wall protruding from the first side wall is used to abut against the end of the side wall of the frame groove.
[0010] In one embodiment, the main body has a first end and a second end located in the third direction, the first end of the main body is used to extend into the frame groove, and the limiting groove is arranged adjacent to one end of the main body;
[0011] The limiting groove has a first side wall and a second side wall in a third direction, wherein the first side wall is arranged close to the first end of the main body, and the second side wall is provided with a limiting portion, and the limiting portion is used to abut against an inner side wall of the frame groove.
[0012] In one embodiment, the second side wall is protruded along the third direction to form the limiting portion, and the limiting portion extends along the second direction.
[0013] In one embodiment, a rounded corner is provided between the first side wall and the bottom wall of the limiting groove in the first direction.
[0014] In one embodiment, the body comprises:
[0015] A bearing portion extends along the second direction, and a side of the bearing portion in the first direction is a bearing side, and the bearing side is provided with a side convex portion; and
[0016] The operating portion extends along the third direction, and one end of the operating portion is opposite to and spaced from the side protrusion in the third direction. The operating portion is connected to one end of the bearing portion, and the operating portion and the side protrusion define the limiting groove.
[0017] In one embodiment, the elastic supporting member is provided in plurality, and the plurality of elastic supporting members are distributed along the second direction.
[0018] In one embodiment, a mounting post is provided on the second side of the body;
[0019] The elastic support member comprises:
[0020] A support seat, slidably sleeved on the mounting column; and

[0022] In one embodiment, the attachment jig further includes a rolling element, and the rolling element is mounted on an end of the support seat away from the main body in the first direction.
[0023] In the technical solution of the present 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 member. When the attachment jig is in use, one end of the elastic support member abuts against an inner side wall of the frame groove, and the elastic force of the elastic support member is transmitted toward the main body, pushing the main body to move toward the other inner side wall of the frame groove, so that the extruded strip fits the inner side wall of the frame groove. At this time, the elastic support member is still in a compressed state, and the elastic support member still provides elastic force to the main body. The main body applies pressure to the extruded strip, thereby achieving pressure maintenance for the extruded strip. According to the pressure required for pressure maintenance, a suitable elastic support member is selected. Thereby, the extruded strip is subjected to appropriate pressure during pasting, ensuring that the extruded strip can be firmly pasted in the frame groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0037] Due to the existing installation process of the extruded strip, the pressure holding when bonding the extruded strip to the back panel is insufficient, resulting in an insufficiently firm bonding. The backlight module will generate high temperatures when in use. Under the action of high temperatures, the extruded strip is prone to falling off. In addition, insufficient pressure holding of the extruded strip in the backlight assembly may cause damage to the function of the backlight assembly: For the backlight assembly, insufficient pressure holding of the extruded strip may affect its sealing and protection of light. This may cause light leakage or uneven distribution, thereby affecting the brightness and contrast of the display.
[0038] In order to solve the problem of insufficient pressure holding of the extruded strip, the following measures can be taken: optimize the process parameters, and ensure that the extruded strip is fully compacted during the bonding process by adjusting the pressure holding time, pressure and other parameters. Provide uniform pressure distribution during bonding to avoid insufficient local pressure holding. Through the above measures, the pressure holding effect of the extruded strip in the backlight assembly can be effectively improved, thereby improving the performance and reliability of the entire backlight module.
[0039] In order to improve the problem that the extruded strip is easy to fall off under high temperature due to insufficient pressure holding during assembly, the present invention provides an attachment jig.
[0040] See also Figure 1 to Figure 2 In one embodiment of the present invention, the attaching jig 100 is used to attach the extruded strip 200 to an inner wall of the frame groove 300 of the display device, and the attaching jig 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, and the first side of the main body 1 is used for placing the extruded strip 200; and the elastic support member 2 is arranged on the second side of the main body, and 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 the present 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 member 2. When the attachment jig 100 is in use, one end of the elastic support member 2 abuts against an inner wall of the frame groove 300, and the elastic force of the elastic support member 2 is transmitted toward the main body 1, pushing the main body 1 to move toward 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 member 2 is still in a compressed state, and the elastic support member 2 still provides elastic force to the main body 1. The main body 1 applies pressure to the extruded strip 200, thereby achieving pressure maintenance of the extruded strip 200. According to the pressure required for pressure maintenance, a suitable elastic support member 2 is selected. Thereby, the extruded strip 200 is subjected to appropriate pressure during pasting, ensuring that the extruded strip 200 can be firmly pasted in the frame groove 300. Among them, the elastic support member 2 includes multiple types, such as spring 23 elastic elements, diaphragm elastic elements and rubber elastic elements. In this design, rubber elastic elements are not used because rubber elastic elements are prone to aging and the elastic force they can provide will also change. In addition, the elastic support member 2 only provides elastic force to the main body 1. As for whether the elastic support member 2 is fixedly connected to the main body 1, it is not limited here and will be discussed later.
[0042] Since the extruded strip 200 is in the shape of a long strip, when the extruded strip 200 is placed on the main body 1, the extruded strip 200 can be limited to a certain position, so that the extruded strip 200 can be pasted by operating the pasting fixture 100. In one embodiment of the present invention, please refer to Figure 2 and Figure 3, by setting a limiting groove 11, the extruded strip 200 is limited to a certain extent, and the first side of the main body 1 is provided with a limiting groove 11 extending along the second direction, and the limiting groove 11 is used to accommodate the extruded strip 200. The limiting groove 11 extends along the second direction, and the extruded strip 200 also extends along the second direction and is placed in the limiting groove 11. The extruded strip 200 and the limiting groove 11 can be an interference fit, or a clearance fit, or a clearance fit, but the gap between the two is not easy to be too large. It is worth mentioning 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 the extruded strip 200 is partially installed in the limiting groove 11 and can be limited by 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 is completely located in the limiting groove 11, and under the action of the elastic support member 2, the main body 1 moves toward an inner wall of the frame groove 300, which will only make the main body 1 abut against the inner wall of the frame groove 300, and the extruded strip 200 cannot abut against the inner wall of the frame groove 300, resulting in the extruded strip 200 being unable to fit on the inner wall of the frame groove 300. Therefore, when the extruded strip 200 is installed in the limiting groove 11, it must protrude from the limiting groove 11, and after being subjected to the maximum holding pressure and producing a certain deformation, there is still a part protruding from the limiting groove 11.
[0043] See also Figure 2When the attachment jig 100 is in use, the main body 1 does not need to be fully extended into the frame groove 300. It is only necessary for the limiting groove 11 to partially extend into the frame groove 300 together with the extruded strip 200, and the extruded strip 200 can be attached to the inner wall of the frame groove 300. The main body 1 also has a portion located outside the frame groove 300, so that the attachment jig 100 can be taken out of the frame groove 300 after the attachment is completed, and the position of the limiting groove 11 can be adjusted during the attachment process, 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 arranged adjacent to one end of the main body 1, and the second end is located outside the frame groove 300 for operation. In order to make the extruded strip 200 completely installed in the frame groove 300, and ensure aesthetics while also ensuring a certain degree of straightness, the limiting groove 11 has a first side wall and a second side wall in the third direction, wherein the first side wall is arranged near the first end of the main body 1, wherein the second side wall is arranged higher than the first side wall in the direction from the second side of the main body 1 and outward, and the portion of the second side wall protruding from the first side wall is used to abut against the end of the side wall of the frame groove 300. During use, when 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 side wall of the limiting groove 11 abuts against the end of the side wall of the frame groove 300, it cannot continue to extend. At this time, the limiting groove 11 is just completely located in the frame groove 300, so at least the portion of the extruded strip 200 located in the limiting groove 11 is also located in the frame groove 300. This ensures that after attachment, no part of the extruded strip 200 protrudes from the frame groove 300.
[0044] See also Figure 2 and Figure 4The main body 1 is a component used to carry the extruded strip 200, and is also a component that transmits the elastic force of the elastic support member 2. For the elastic support member 2, the direction of deformation is unstable, and the elastic force is not necessarily transmitted along the first direction. Perhaps there is a certain angle between the direction of the elastic force and the first direction; in addition, when operating the main body 1, the plane of the main body 1 carrying the extruded strip 200 is not necessarily perpendicular to the first direction. At this time, the main body 1 is in a skewed state. The above two situations will cause the main body 1 to produce a certain torque, so that one side of the extruded strip 200 in the third direction is subjected to a larger holding pressure, while the other side is subjected to a smaller holding pressure. Therefore, the distribution of the holding pressure is not uniform, and the overall attachment effect does not meet the requirements. In order to prevent the main body 1 from being subjected to a certain torque, it is necessary to limit the main body 1 so that the main body 1 can only move along the first direction, so that the force transmission is always transmitted 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 offset by the action of the limit due to the limitation of the limit. Specifically, when the second side wall of the limiting groove 11 abuts against the end of the side wall of the frame groove 300, the first side wall of the limiting groove 11 also abuts against the bottom wall of the frame groove 300 in the third direction. At this time, during the operation of the attachment jig 100, the user only needs to apply a force along the third direction toward the first side wall of the limiting groove 11 to ensure that the first side wall of the limiting groove 11 abuts against the bottom wall of the frame groove 300 in the third direction to prevent the rotation of the main body 1. In addition, to prevent the main body 1 from deflecting, the second side wall is provided with a limiting portion 131, and the limiting portion 131 is used to abut against an inner side wall of the frame groove 300. During the normal pressure holding process, there is a certain gap between the limiting portion 131 and the frame groove 300, or they just fit together, and there is no force between the two. Only when the main body 1 deflects, the limiting portion 131 and the frame groove 300 will abut against each other, thereby limiting the deflection and ensuring the attachment effect. Since the limiting portion 131 is arranged on the second side wall, there is a clearance fit between the limiting groove 11 and the extruded strip 200, so that the limiting portion 131 will not interfere with the extruded strip 200 in the third direction to cause deformation of the extruded strip 200. In addition, the existence of the limiting portion 131 makes the installation position of the extruded strip 200 closer to the inside relative to the opening position of the frame groove 300. The specific arrangement of the limiting portion 131 is as follows: the second side wall is protruded along the third direction to form the limiting portion 131, and the limiting portion 131 extends along the second direction. Generally, the limiting portion 131 is arranged perpendicular to the first direction on a side away from the bottom of the limiting groove 11 in the first direction.
[0045] See also Figure 3 and Figure 4, there are generally four frame grooves 300 of the back plate, and they have two dimensions of length and width, and both dimensions are relatively large, and the length of the frame groove 300 of each back plate is different. In order to improve the versatility of the attachment fixture 100, the size of the main body 1 in the second direction is designed to be smaller, smaller than the size of the frame groove 300 in the second direction, and the main body 1 can be moved along the second direction, so as to correct the position of the extruded strip 200 and maintain pressure at various locations. Based on this design idea, the main body 1 and the extruded strip 200 slide relatively along the second direction. Since the main body 1 is used to carry the extruded strip 200, the friction between the extruded strip 200 and the bottom of the limiting groove 11 is inevitable. In order to reduce the friction between the main body 1 and the extruded strip 200, so as to ensure a certain degree of smoothness when the main body 1 moves along the second direction, it is necessary to avoid the side of the extruded strip 200 from fitting with the side of the limiting groove 11, so a rounded corner is set between the first side wall and the bottom wall of the limiting groove 11 in the first direction. Due to the setting of the fillet, the part of the extruded strip 200 close to the bottom of the limiting groove 11 in the first direction is difficult to approach the first side wall, so that the extruded strip 200 is spaced apart from the first side wall. If the side and bottom of the extruded strip 200 are also provided with fillets, it is only necessary to make the fillet diameter between the first side wall and the bottom wall larger than the fillet diameter between the side and bottom of the extruded strip 200. In addition, the second side wall and the bottom wall of the limiting groove 11 in the first direction can also be rounded. Fillets can be set, but the gap between the limiting groove 11 and the extruded strip 200 cannot be too large, otherwise the straightness of the extruded strip 200 during assembly cannot be guaranteed. For the friction between the bottom of the limiting groove 11 and the extruded strip 200, a through hole can be set, one end of the through hole is located at the bottom of the limiting groove 11, and the other end extends to the outside of the main body 1 along the third direction. By adding lubricant into the through hole, the lubricant reduces the friction coefficient between the bottom of the limiting groove 11 and the extruded strip 200, thereby reducing the friction force.
[0046] See also Figure 4 , wherein the specific setting structure of the main body 1 is as follows; the main body 1 includes: a bearing part 12 and an operating part 13; the bearing part 12 extends along the second direction, and the side thereof in the first direction is the bearing side, and the bearing side is provided with a side protrusion 121; and the operating part 13 extends along the third direction, and one end of the operating part 13 is opposite to and spaced from the side protrusion 121 in the third direction, and the operating part 13 is connected to one end of the bearing part 12, and the operating part 13 and the side protrusion 121 define the limiting groove 11. The plane of the bearing part 12 for placing the extruded strip 200 is perpendicular to the first direction. The bearing part 12 needs to be fully extended into the frame groove 300, while the operating part 13 is located outside the frame groove 300, and an external force is applied by the multi-operating part 13 to move the main body 1 along the second direction.
[0047] In order to ensure that the extruded strip 200 is fully pressurized during the attachment process, thereby ensuring the installation quality of the extruded strip 200, the requirements for the pressure holding pressure are taken into consideration. To achieve this goal, a plurality of elastic support members 2 are provided in the attachment jig 100. Such a design can disperse the pressure borne by a single elastic support member 2, thereby reducing the performance requirements for each elastic support member 2. In this way, it is prevented that the elastic force required to be provided by a single elastic support member 2 is particularly large. On the one hand, the cost of such an elastic support member 2 is relatively high, and on the other hand, it will cause local pressure concentration and uneven pressure distribution. In order to further ensure that the force applied to various parts of the main body 1 is uniform, in terms of layout, such as Figure 1 and Figure 2 As shown, multiple elastic support members 2 are evenly distributed along the second direction. This distribution method can effectively transfer pressure to various parts of the main body 1, avoiding deformation or damage caused by excessive local force. In addition, this evenly distributed design also helps to improve the stability and repeatability of the attachment process, thereby ensuring the quality of the extruded strip 200 attachment. 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 also be arranged at intervals in the third direction. In this way, uniform distribution of force can be achieved in the third direction. The benefits of doing so are multifaceted. First, it can ensure that the force of each part in the third direction is uniform, avoiding insufficient local pressure caused by uneven force. Secondly, by evenly distributing the elastic support members 2 in the third direction, the generation of such torque can be effectively avoided, thereby improving the attachment quality of the extruded strip 200.
[0048] The specific structure of the elastic support member 2 is as follows: the elastic support member 2 includes a support seat 22 and a spring 23, the support seat 22 has a rod extending in a first direction, one end of the rod away from the main body 1 extends circumferentially to form a stopper, the spring 23 is sleeved on the rod, and the size of the spring 23 in the first direction is longer than the size of the rod in the first direction, the two ends of the spring 23 in the first direction are respectively in contact with the stopper and the main body 1, and the spring 23 is always in a compressed state. In addition, in order to integrate the various components and avoid the need to reassemble each component before use, the two ends of the spring 23 in the first direction are respectively fixedly connected to the main body 1 and the stopper. In order to keep the position of the elastic support member 2 corresponding to the main body 1 in the third direction unchanged (especially when the main body 1 is provided with only one elastic support member 2 in the third direction, the elastic support member 2 is required to correspond to the center position of the main body 1 in the third direction), a mounting column 21 is provided on the second side of the main body 1; the rod portion is provided with an opening corresponding to the mounting column 21, and the mounting column 21 is at least partially inserted into the opening so that the support seat 22 is slidably sleeved on the mounting column 21. In the structure of the elastic support member 2, in order 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 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 attached fixture. At the same time, the material of the spring 23 should also be selected from materials with high elasticity and fatigue resistance, such as stainless steel or special alloys, 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 are respectively in contact with the stopper and the main body 1, but are not fixedly connected between the main body 1 and the stopper, wherein the support seat 22 is sleeved and limited on the mounting column 21, and can slide along the mounting column 21, but cannot be separated from the mounting column 21, and the support seat 22 itself is detachable. After the support seat 22 is disassembled, it can be separated from the mounting column 21, and the spring 23 can be replaced at this time, and the support seat 22 can be assembled after the spring 23 is replaced. This setting method can replace different springs 23 according to the demand for pressure holding pressure.
[0050] Since the attachment jig 100 is to be moved in the second direction, the attachment jig 100 also includes a rolling member 3, which must be able to roll in the second direction, so the rolling member 3 can be a ball or a roller, but when the attachment jig 100 is used, 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 the third direction, so the rolling member 3 is set in the form of a ball, and the ball can roll in multiple different directions to meet the requirements. The rolling member 3 is installed at the end of the support seat 22 away from the main body 1 in the first direction, and abuts against an inner side wall of the frame groove 300. As for the installation method of the ball, first of all, the support seat 22 includes two parts distributed along the first direction, the part close to the main body 1 is the first part, and the part away from the main body 1 is the second part. The first part is provided with a groove in the middle of one side facing the second part in the first direction, and the groove is for the ball to be placed, and the ball protrudes from the opening plane of the groove in the third direction. However, when the attachment fixture 100 is used and the frame groove 300 is pulled out, the ball will be out of the groove due to lack of support from the inner side of the frame groove 300, so the second part is provided with a through hole corresponding to the groove position. When the first part is fixedly connected to the second part, the second part limits the ball in the first direction, so that the ball cannot be out of the groove. In addition, the through hole through which the ball is penetrated protrudes from the end face of the second part, but the maximum cross-section of the ball cannot pass through the through hole. Therefore, the ball can play a rolling role and cannot be separated from the support seat 22. Among them, multiple grooves can be provided on the first part, and multiple balls can be installed, and multiple through holes are correspondingly provided on the second part.
[0051] In the process of designing and applying the attachment jig 100, for a specific product, the extruded strip 200, the top of the first direction of the extruded strip 200 is designed to be a flat plane, which is perpendicular to the first direction. Such a design is intended to ensure that the attachment jig 100 can obtain the maximum attachment area when in use. This design ensures the stability of the attachment. In addition, the bottom of the first direction of the extruded strip 200 adopts a unique design combining two curved surfaces and a plane. The purpose of this design is to enable the inner curved surface of the extruded strip 200 away from the opening of the frame groove 300 to better remove the attachment jig 100 after installation. Such a design takes into account the convenience and efficiency of operation, ensuring that the attachment jig 100 can be easily removed from the product after completing its function. At the same time, the outer curved surface design of the extruded strip 200 close to the opening of the frame groove 300 takes into account the need for backlighting. The existence of this outer curved surface allows the light to be more evenly distributed when backlit, thereby improving the overall optical effect of the product. In addition, this design also facilitates the insertion of components such as the optical film and the diffuser in the backlight assembly, providing convenience for subsequent assembly work. In the design of the extruded strip 200, in addition to the inner and outer curved surfaces, the saved plane length is also an important consideration. This plane length should not be too small, otherwise it will not be possible to effectively fix components such as the optical film and the diffuser at the bottom of the extruded strip 200. In order to ensure that these components can be firmly installed on the extruded strip 200, it is generally recommended that this plane 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 attaching jig 100 is as follows: 1. Select the inner side of the back panel groove to be processed; 2. Starting from one end of any side, place the extruded strip 200 (with the adhesive side facing up) in the limiting groove 11 of the attaching jig 100; 3. Tear off the double-sided adhesive release paper on the extruded strip 200 (the tearing length exceeds the length of the attaching jig 100 in the second direction); 4. Insert the compressed jig into the frame groove 300 of the back panel and make close contact with the inner side of the frame groove 300; 5. Move the attaching jig 100 while tearing off the double-sided adhesive (keeping the moving direction consistent); 6. Complete the first attachment; 7. Move the attaching jig 100 in the opposite direction to complete the secondary pressure holding; 8. Compress the attaching jig 100 and remove the attaching jig 100 from the back panel frame groove 300.
