Description

Technical Field

[0001] The present invention relates to the technical field of television assembly, and in particular to a television light bar fixing and installation module and an installation method thereof. Background Art

[0002] During the TV manufacturing process, light bar installation is a crucial step. Currently, TV light bar installation is typically done by directly attaching the light bar to the back panel using adhesive. However, this traditional installation method has numerous drawbacks.

[0003] Over long-term use, the colloid is prone to aging, and its viscosity gradually deteriorates. This can cause the light strip to easily shift or loosen during use. This shifting and loosening of the light strip not only affects the normal use of the TV, but can also adversely affect the display quality.

[0004] During installation, workers often apply too much glue to ensure the stability of the light strip's adhesion. This excessive amount of glue can cause the thickness of the raised portion of the light strip to be excessive, resulting in a height difference between the light beads and other parts. This height difference can affect the uniformity of the TV display and reduce the display quality.

[0005] In summary, how to ensure the stability of the bonding during long-term use of the TV light strip during installation while avoiding uneven installation dimensions caused by improper glue control has become a technical problem that needs to be solved in the field of TV assembly technology. Summary of the Invention

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention provides a module for fixing and mounting a television light bar, comprising a light bar module and a backplate structure for fixing and mounting multiple light bar modules. The backplate structure is evenly distributed with multiple inwardly concave sunken portions. The sunken portions are provided with inverted tapered grooves and bottom groove areas from the outside to the inside. The annular sidewalls of the inverted tapered grooves are roughened annular surfaces. The sunken portions are fastened with cone-head screws. The cone-head screws comprise an integrally formed screw portion, a straight rod portion, and an inverted tapered portion.

[0008] The light bar module includes a light board, LED lamp beads fixed to the upper side of the light board, and a lower screw cone barrel fixed to the lower side of the light board and integrally formed with the light board, wherein the LED lamp beads are aligned with the lower screw cone barrel. A plurality of rubber strip grooves and a plurality of rubber strip grooves are provided in the connection area between the bottom surface of the light board and the lower screw cone barrel, wherein the rubber strip grooves are connected to the side surface of the light board. The lower screw cone barrel includes an external threaded surface and a threaded barrel cavity with an opening facing downward, wherein a gap is left between the external threaded surface of the lower screw cone barrel and the rough annular surface of the inverted cone groove, and a threaded structure is provided on the inner wall surface of the threaded barrel cavity. The inverted cone portion and straight rod portion of the cone head screw are inserted into the threaded barrel cavity of the lower screw cone barrel.

[0009] As a preferred technical solution of the TV light bar fixing and installation module of the present invention: the cone head screw is made of metal or plastic material, wherein the top surface of the inverted cone portion is provided with a cross slot that matches the screwdriver head.

[0010] As a preferred technical solution of the TV light bar fixing and installation module of the present invention: the innermost plate of the sunken part is provided with a bottom screw hole connected to the bottom groove area, and the screw part is fastened and screwed at the bottom screw hole.

[0011] As an optimal technical solution for the TV light bar fixing and installation module of the present invention: the radial dimension of the lower spiral cone barrel is smaller than the radial dimension of the inverted cone groove, and the vertical height dimension of the lower spiral cone barrel is the same as the vertical depth dimension of the inverted cone groove.

[0012] As an optimal technical solution for the TV light bar fixing and installation module of the present invention, the diameter of the top surface of the inverted cone is larger than the diameter of the straight rod, and the diameter of the top surface of the inverted cone is smaller than the inner diameter of the threaded cylinder cavity.

[0013] As an optimal technical solution for the TV light bar fixing and installation module of the present invention: the vertical length dimension of the straight rod part is greater than the vertical depth dimension of the bottom groove area, and the total length dimension of the inverted cone part and the straight rod part inserted into the threaded barrel cavity is less than the vertical depth dimension of the threaded barrel cavity.

[0014] As a preferred technical solution of the TV light bar fixing and installation module of the present invention, the top of the threaded cylindrical cavity is arranged at a position higher than the top receiving groove of the top surface of the inverted cone.

[0015] The present invention provides a method for installing a TV light bar fixed installation module, comprising the following contents:

[0016] Step 1: Preparation before construction: comprehensively check the sunken part of the back plate structure to ensure that the processing accuracy of the inverted cone groove and bottom groove area meets the standards, and at the same time confirm that the roughness of the rough ring surface meets the colloid adhesion requirements.

[0017] Step 2: Using the installation tool, install the cone head screws in each sunken part of the back panel structure according to the preset installation points. After installation, carefully check the verticality of the straight shaft and the inverted cone of the cone head screw. If any tilt is found, replace the cone head screw immediately.

[0018] Step 3: Based on the pre-coated glue position planning, accurately apply the glue and inject excess glue into the inverted cone groove and bottom groove area where the cone head screws have been installed to ensure sufficient glue during the subsequent installation process.

[0019] Step 4: Take the light bar module, align the threaded barrel cavity of the lower screw cone barrel at the end of the light board accurately with the inverted cone part of the cone head screw, and then slowly and vertically apply downward pressure to make the lower screw cone barrel initially dock with the inverted cone groove.

[0020] Step 5: Continue to apply pressure to force part of the colloid in the bottom groove area to enter the threaded barrel cavity and fully fill the space between the inverted cone part, the straight rod part and the inner wall thread of the threaded barrel cavity.

[0021] At the same time, the remaining colloid in the bottom groove area and the colloid in the inverted cone groove fills the gap between the external thread surface and the rough annular surface and overflows upward.

[0022] Step 6: When the overflowed colloid enters the rubber strip groove and the rubber strip groove, press the matching position of the lower cone barrel and the sinking part evenly with force, and at the same time press the surrounding light board area appropriately to discharge the excess colloid from the rubber strip groove until the light board at this position fits tightly with the back panel structure.

[0023] Step 7: Follow the operation methods of steps 4 to 6 above to complete the bonding and installation work of the entire light strip module and each connection point of the back panel structure in sequence, ensuring that the accuracy of each installation position meets the assembly requirements.

[0024] Step 8: After the overall installation is completed, use special cleaning tools to carefully clean the colloid overflowing from the light panel surface and the rubber strip groove to ensure that the installation surface is clean and there is no colloid residue.

[0025] Compared with the existing technology, the beneficial effects of the present invention are:

[0026] 1. The present invention forms a multi-fixing structure through the rational design of the sunken part, inverted conical groove, bottom groove area and cone head screw of the back plate structure, combined with the cooperation of the lower screw cone barrel and cone head screw of the light bar module, and added with colloid filling, which effectively improves the stability of the light bar installation and solves the problem of easy displacement and loosening of the light bar in the traditional installation method.

[0027] 2. The present invention provides a glue strip groove and a glue strip containing groove on the bottom surface of the lamp panel, which can reasonably guide and contain overflowed glue during the installation process, avoiding local bulges of the light bar caused by excessive glue, ensuring the uniformity of the installation size of the light bar, and preventing height differences in the positions of the lamp beads, thereby ensuring the uniformity of the TV display; and the top containing groove on the top of the threaded barrel cavity can accommodate excess glue, making the coordinated installation of the cone head screw and the threaded barrel cavity more labor-saving and convenient; the gap design between the lower screw cone and the inverted cone groove facilitates the discharge of glue. These designs make the entire installation process simpler and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1: The structure of the TV light bar fixing and installation module of the present invention is as follows:

[0038] (1) Backplane structure: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The backplate structure 1 is used to securely mount multiple light bar modules 3. Its surface is uniformly distributed with multiple inwardly concave depressions 101. Each depression 101 is defined, from the outside inward, by an inverted conical groove 102 and a bottom groove area 103. The sidewalls of the inverted conical groove 102 are roughened to form a ring surface 105. This roughness facilitates adhesive adhesion and enhances the stability of the connection. The innermost plate of the depression 101 features a bottom screw hole 104 that connects to the bottom groove area 103 and is used to securely mount a cone-head screw 2.

[0039] (2) Cone head screw: such as Figure 5 、 Figure 6 、 Figure 7 The cone head screw 2 is made of metal or plastic material, and includes an integrally formed screw portion 201, a straight rod portion 202 and an inverted cone portion 203. A cross slot that matches the screwdriver head is provided on the top surface of the inverted cone portion 203, which is convenient for installation using a screwdriver. The diameter of the top surface of the inverted cone portion 203 is larger than the diameter of the straight rod portion 202, and the diameter of the top surface of the inverted cone portion 203 is smaller than the inner diameter of the threaded barrel cavity 3032, to ensure that it can be smoothly inserted into the threaded barrel cavity 3032 of the light bar module 3. The vertical length dimension of the straight rod portion 202 is larger than the vertical depth dimension of the bottom groove area 103, and the total length dimension of the inverted cone portion 203 and the straight rod portion 202 inserted into the threaded barrel cavity 3032 is smaller than the vertical depth dimension of the threaded barrel cavity 3032. This design provides a reasonable space for colloid filling and installation of the light board 301.

[0040] (3) Light bar module: Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 The light bar module 3 includes a light board 301, LED lamp beads 302 fixed to the upper side of the light board 301, and a lower spiral cone 303 fixed to the lower side of the light board 301 and integrally formed with the light board 301. The LED lamp beads 302 are aligned with the lower spiral cone 303 because the LED lamp beads 302 generate relatively more heat and are difficult to dissipate. Placing the lower spiral cone 303 directly below the LED lamp beads 302 can improve the installation security of the light board 301 at this location.

[0041] like Figure 4 、 Figure 6 、 Figure 7 The connection area between the bottom surface of the light board 301 and the lower screw cone 303 is provided with a number of rubber strip grooves 3011 and a number of rubber strip grooves 3012. The rubber strip grooves 3011 are connected to the side of the light board 301. When the lower screw cone 303 is pressed down into the inverted cone groove 102, the colloid in the inverted cone groove 102 overflows. The rubber strip grooves 3012 can accommodate the overflowed colloid. If too much colloid overflows, it can be discharged from the bottom area of ​​the light board 301 through the rubber strip grooves 3011, so that the light board 301 and the back panel structure 1 are closely fitted and the height difference of the local adhesive installation is avoided. In addition, the rubber strip grooves 3012 and the rubber strip grooves 3011 increase the amount of glue between the light board 301 and the back panel structure 1, which to a certain extent enhances the connection strength.

[0042] like Figure 6 、 Figure 7The lower conical screw barrel 303 includes an externally threaded surface 3031 and a downwardly opening threaded barrel cavity 3032. A gap is left between the externally threaded surface 3031 of the lower conical screw barrel 303 and the roughened annular surface 105 of the inverted cone groove 102. This gap facilitates the discharge of the colloid during installation. The roughened annular surface 105 and the externally threaded surface 3031 also limit the displacement of the solidified colloid. The inner wall of the threaded barrel cavity 3032 is provided with a threaded structure for mating with the cone head screw 2. The solidified colloid between the inner wall of the threaded barrel cavity 3032 and the cone head screw 2 is restrained by the threads and the inverted cone 203, making it difficult to shift, thus ensuring a more stable connection.

[0043] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 The top of the threaded barrel cavity 3032 is provided with a top receiving groove 3033 positioned higher than the top surface of the inverted cone portion 203. When the inverted cone portion 203 and the straight rod portion 202 are inserted into the threaded barrel cavity 3032 and the colloid enters, the top receiving groove 3033 can accommodate excess colloid, facilitating the easy and labor-saving installation of the tapered head screw 2 and the threaded barrel cavity 3032. The radial dimension of the lower screw cone 303 is smaller than the radial dimension of the inverted cone groove 102, and its vertical height dimension is the same as the vertical depth dimension of the inverted cone groove 102, ensuring that the lower screw cone 303 and the inverted cone groove 102 can be precisely connected.

[0044] Example 2: The installation method of the TV light bar fixed installation module of the present invention is as follows:

[0045] Step 1: Pre-construction preparation: Thoroughly inspect the sunken portion 101 of the backplate structure 1 to ensure that the machining accuracy of the inverted cone groove 102 and the bottom groove area 103 meet the standards. Confirm that the roughness of the rough annular surface 105 meets the requirements for colloid adhesion, laying the foundation for subsequent bonding strength.

[0046] Step 2: Installing the Tapered Head Screws: Using a screwdriver, install the tapered head screws 2 in each of the sunken portions 101 of the backplate structure 1, sequentially according to the pre-set installation points. After installation, carefully check the vertical alignment of the straight shaft 202 and the inverted tapered portion 203 of the tapered head screws 2. If any tilt is detected, replace the tapered head screws 2 promptly to ensure accurate installation.

[0047] Step 3: Applying colloid: Apply colloid precisely according to the pre-applied glue location plan. Inject excess colloid into the inverted cone groove 102 and bottom groove area 103 where the cone head screw 2 has been installed to ensure sufficient colloid during subsequent installation.

[0048] Step 4: Align the lower screw cone with the cone head screw: Take the light bar module 3 and align the threaded barrel 3032 of the lower screw cone 303 at the end of the light board 301 with the inverted cone 203 of the cone head screw 2. Then, slowly and vertically apply downward pressure to initially align the lower screw cone 303 with the inverted cone groove 102.

[0049] Step 5: Colloid Filling: Continuously applying pressure forces a portion of the colloid in the bottom groove area 103 into the threaded barrel cavity 3032, where it is fully filled between the inverted tapered portion 203, the straight rod portion 202, and the inner threads of the threaded barrel cavity 3032. Simultaneously, the remaining colloid in the bottom groove area 103 and the colloid in the inverted tapered groove 102 fills the gap between the outer thread surface 3031 and the rough annular surface 105, overflowing upward.

[0050] Step 6: Remove Excess Colloid: After the overflowed colloid enters the adhesive strip groove 3012 and the adhesive strip groove 3011, evenly press the lower cone 303 and the sinking part 101 at the mating position, while also appropriately pressing the surrounding area of ​​the light board 301. Excess colloid is drained from the adhesive strip groove 3011 until the light board 301 at this position is tightly fitted with the back panel structure 1 to ensure smooth installation.

[0051] Step 7: Complete the installation of all connection points: Follow the procedures from Steps 4 to 6 above to complete the bonding and installation of all connection points between the entire light bar module 3 and the back panel structure 1. Ensure that the accuracy of each installation position meets the assembly requirements to ensure the installation quality of the entire module.

[0052] Step 8: Cleaning Spilled Colloid: After the overall installation is complete, use a dedicated cleaning tool to carefully clean any spilled colloid from the surface of the light panel 301 and the rubber strip groove 3011. Ensure that the installation surface is clean and free of colloid residue, ensuring that the module's appearance and performance meet the requirements.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
