Description

Technical Field

[0001] This invention relates to the field of television assembly technology, and in particular to a television light strip fixing module and its installation method. Background Technology

[0002] In the manufacturing process of television sets, the installation of the backlight strip is a crucial step. Currently, the backlight strip is typically installed by directly attaching it to the back panel using adhesive. However, this traditional installation method has many drawbacks.

[0003] From a long-term usage perspective, the colloid is prone to aging, and its adhesion will gradually deteriorate. This makes the LED strip prone to shifting and loosening during use. Shifting and loosening of the LED strip not only affect the normal operation of the television but may also adversely affect the display quality.

[0004] During installation, to ensure the stability of the LED strip adhesion, workers often apply too much adhesive. Excessive adhesive can cause excessive thickness of localized protrusions in the LED strip, resulting in a height difference between the LEDs and other parts. This height difference affects the uniformity of the television display and reduces its display quality.

[0005] In conclusion, ensuring the stability of the light strip's adhesion during long-term use and avoiding uneven installation dimensions due to improper glue control during the installation process has become a pressing technical problem in the field of television assembly technology. Summary of the Invention

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

[0007] This invention provides a TV backlight strip fixing module, including a backlight strip module and a back plate structure for fixing multiple backlight strip modules. The back plate structure has multiple recessed recesses evenly distributed. Each recess has an inverted conical groove and a bottom groove area from the outside to the inside. The circumferential sidewall of the inverted conical groove is a rough circumferential surface. A conical screw is fastened to the recess. The conical screw includes an integrally formed screw part, a straight shank part, and an inverted conical part.

[0008] The LED strip module includes an LED panel, LED beads fixed to the upper side of the LED panel, and a lower screw-conical cylinder fixed to the lower side of the LED panel and integrally formed with the LED panel, wherein the LED beads are aligned with the lower screw-conical cylinder. Several adhesive strip grooves and several adhesive receiving grooves are provided in the connection area between the bottom surface of the LED panel and the lower screw-conical cylinder, wherein the adhesive strip grooves are continuous with the side surface of the LED panel. The lower screw-conical cylinder includes an external threaded surface and a downward-opening threaded cylinder cavity, wherein a gap is left between the external threaded surface of the lower screw-conical cylinder and the rough annular surface of the inverted conical groove, and the inner wall of the threaded cylinder cavity is provided with a threaded structure. The inverted conical part and the straight shank part of the conical screw are inserted into the threaded cylinder cavity of the lower screw-conical cylinder.

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

[0010] As a preferred technical solution of the TV light strip fixing and installation module of the present invention: the innermost plate of the recessed part has a bottom screw hole that communicates with the bottom groove area, and the screw part is fastened and screwed at the position of the bottom screw hole.

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

[0012] As a preferred 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 part is larger than the diameter of the straight rod part, and the diameter of the top surface of the inverted cone part is smaller than the inner diameter of the threaded cylinder cavity.

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

[0014] As a preferred technical solution for the TV light bar fixing and installation module of the present invention: a top receiving groove is provided at the top of the threaded cylinder cavity, which is positioned higher than the top surface of the inverted cone.

[0015] This invention provides an installation method for a fixed mounting module for a television light strip, comprising the following:

[0016] Step 1: Pre-construction preparation. Conduct a comprehensive inspection of the sunken part of the back panel structure to ensure that the processing accuracy of the inverted conical groove and bottom groove area meets the standards, and at the same time confirm that the roughness of the rough ring surface meets the requirements for colloid adhesion.

[0017] Step Two: Using installation tools, install the tapered screws sequentially at the pre-set installation points on each recessed part of the back panel structure. After installation, carefully check the verticality of the straight shank and the tapered section of the tapered screw. If any tilting is found, replace the tapered screw immediately.

[0018] Step 3: Based on the pre-applied adhesive location plan, accurately apply the adhesive and inject excess adhesive into the inverted conical groove and bottom groove area where the conical screws have been installed to ensure sufficient adhesive for subsequent installation.

[0019] Step 4: Take out the light strip module, accurately align the threaded cavity of the lower screw tapered cylinder at the end of the light panel with the inverted cone of the cone head screw, and then slowly and vertically apply downward pressure to initially connect the lower screw tapered cylinder with the inverted cone groove.

[0020] Step 5: Continuously apply pressure to encourage some of the colloid in the bottom groove area to enter the threaded cylinder cavity, fully filling the space between the inverted cone section, the straight rod section, and the threads on the inner wall of the threaded cylinder cavity.

[0021] At the same time, the remaining colloid in the bottom groove area and the colloid in the inverted conical groove fill the gap between the external thread surface and the rough annular surface and overflow upwards.

[0022] Step 6: After the overflowing adhesive enters the adhesive groove and the adhesive discharge groove, press down evenly on the mating position of the screw cone and the recessed part, and at the same time press the surrounding light panel area appropriately to discharge the excess adhesive from the adhesive discharge groove until the light panel is tightly attached to the back panel structure at this position.

[0023] Step 7: Following the operation methods of Steps 4 to 6 above, complete the bonding and installation of each connection point between the entire light strip module and 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 a special cleaning tool to carefully clean the excess adhesive from the surface of the light panel and the adhesive strip groove, ensuring that the installation surface is clean and free of adhesive residue.

[0025] Compared with existing technologies, the beneficial effects of this invention are:

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

[0027] 2. This invention, through the glue discharge groove and glue containment groove set on the bottom surface of the lamp panel, can reasonably guide and contain the overflowing glue during the installation process, avoiding local bulging of the lamp strip due to excessive glue, ensuring the uniformity of the lamp strip installation size, preventing height differences in the position of the lamp beads, and thus ensuring the uniformity of the television display; in addition, the top containment groove at the top of the threaded cylinder cavity can accommodate excess glue, making the installation of the tapered screw and the threaded cylinder cavity more labor-saving and convenient; the gap design between the lower threaded tapered cylinder and the inverted tapered groove facilitates glue discharge. All these designs make the entire installation process simpler and more efficient. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0037] Example 1: The structural composition of the TV light strip fixing and mounting module of the present invention is as follows:

[0038] (a) Back panel structure: such as Figure 1 , Figure 2 , Figure 3 , Figure 4 The backplate structure 1 is used to fix and install multiple light strip modules 3, and its surface is uniformly provided with multiple recessed recesses 101. Each recess 101 has an inverted conical groove 102 and a bottom groove area 103 arranged sequentially from the outside to the inside. The circumferential sidewall of the inverted conical groove 102 is a rough circumferential surface 105. This rough design is conducive to the adhesion of the adhesive and enhances the stability of the connection. The innermost plate of the recess 101 has a bottom screw hole 104 communicating with the bottom groove area 103 for fastening and installing the conical screw 2.

[0039] (ii) Conical head screws: such as Figure 5 , Figure 6 , Figure 7 The conical screw 2 is made of metal or plastic and includes an integrally formed screw part 201, a straight shank part 202, and a tapered part 203. The top surface of the tapered part 203 has a cross-shaped groove for mates with a screwdriver tip, facilitating installation with a screwdriver. The diameter of the top surface of the tapered part 203 is larger than the diameter of the straight shank part 202, and smaller than the inner diameter of the threaded cylinder cavity 3032, ensuring smooth insertion into the threaded cylinder cavity 3032 of the light strip module 3. The vertical length of the straight shank part 202 is greater than the vertical depth of the bottom groove area 103, while the total length of the tapered part 203 and the straight shank part 202 inserted into the threaded cylinder cavity 3032 is less than the vertical depth of the threaded cylinder cavity 3032. This design provides reasonable space for the colloid filling and the installation of the light panel 301.

[0040] (iii) LED strip modules: such as Figure 1 , Figure 5 , Figure 6 , Figure 7 The light strip module 3 includes a light panel 301, LED beads 302 fixed to the upper side of the light panel 301, and a lower screw cone 303 fixed to the lower side of the light panel 301 and integrally formed with the light panel 301. The LED beads 302 are aligned with the lower screw cone 303 because the LED beads 302 generate relatively more heat and are difficult to dissipate; the lower screw cone 303 positioned directly below them improves the installation stability of the light panel 301 at that location.

[0041] like Figure 4 , Figure 6 , Figure 7 The area where the bottom surface of the lamp panel 301 connects to the lower screw cone 303 is provided with several adhesive discharge grooves 3011 and several adhesive receiving grooves 3012. The adhesive discharge grooves 3011 are connected to the side surface of the lamp panel 301. During the process of the lower screw cone 303 being pressed down into the inverted cone groove 102, the adhesive in the inverted cone groove 102 overflows. The adhesive receiving grooves 3012 can accommodate the overflowing adhesive. If too much adhesive overflows, it can be discharged from the bottom surface area of ​​the lamp panel 301 through the adhesive discharge grooves 3011, which facilitates a tight fit between the lamp panel 301 and the back plate structure 1 and avoids local bonding height differences. Moreover, the adhesive receiving grooves 3012 and adhesive discharge grooves 3011 increase the amount of adhesive between the lamp panel 301 and the back plate structure 1, which enhances the connection strength to a certain extent.

[0042] like Figure 6 , Figure 7The lower threaded cone 303 includes an external threaded surface 3031 and a downward-opening threaded cavity 3032. A gap exists between the external threaded surface 3031 of the lower threaded cone 303 and the rough annular surface 105 of the inverted conical groove 102. This gap facilitates the discharge of adhesive during installation, while the rough annular surface 105 and the external threaded surface 3031 limit the displacement of the cured adhesive. The inner wall of the threaded cavity 3032 is provided with a threaded structure for mating with the conical screw 2. The cured adhesive between the inner wall of the threaded cavity 3032 and the conical screw 2 is constrained by the threads and the inverted conical portion 203, making displacement difficult and resulting in a more stable connection.

[0043] like Figure 3 , Figure 4 , Figure 6 , Figure 7 The top of the threaded cylinder cavity 3032 is provided with a top receiving groove 3033, which is 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 cylinder cavity 3032 and the colloid enters, the top receiving groove 3033 can accommodate excess colloid, facilitating the effortless and convenient installation of the tapered screw 2 with the threaded cylinder cavity 3032. The radial dimension of the lower threaded cone cylinder 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, to ensure that the lower threaded cone cylinder 303 and the inverted cone groove 102 can be precisely aligned.

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

[0045] Step 1: Pre-construction preparation: Conduct a comprehensive inspection of the recessed portion 101 of the back panel structure 1 to ensure that the machining accuracy of the inverted conical groove 102 and the bottom groove area 103 meets the standards. Confirm that the roughness of the rough annular surface 105 meets the requirements for adhesive adhesion, laying the foundation for subsequent bonding strength.

[0046] Step 2: Installing the conical screws: Using a screwdriver, install the conical screws 2 in sequence on each recessed part 101 of the back plate structure 1 according to the preset installation points. After installation, carefully check the verticality of the straight shank 202 and the inverted conical part 203 of the conical screw 2. If any tilting is found, replace the conical screw 2 in time to ensure the accuracy of installation.

[0047] Step 3: Applying Adhesive: Based on the pre-applied adhesive location plan, accurately apply the adhesive. Inject excess adhesive into the inverted conical groove 102 and bottom groove area 103 where the conical screw 2 has been installed to ensure sufficient adhesive during subsequent installation.

[0048] Step 4: Connecting the lower screw tapered cylinder and the conical screw: Take the light strip module 3 and accurately align the threaded cavity 3032 of the lower screw tapered cylinder 303 at the end of the light panel 301 with the inverted conical part 203 of the conical screw 2. Then, slowly and vertically apply downward pressure to initially connect the lower screw tapered cylinder 303 with the inverted conical groove 102.

[0049] Step 5, Colloid Filling: Continuous pressure is applied, causing a portion of the colloid in the bottom groove region 103 to enter the threaded cylinder cavity 3032, fully filling the space between the inverted cone portion 203, the straight rod portion 202, and the threads on the inner wall of the threaded cylinder cavity 3032. Simultaneously, the remaining colloid in the bottom groove region 103 and the colloid in the inverted cone groove 102 fill the gap between the external thread surface 3031 and the rough annular surface 105, overflowing upwards.

[0050] Step Six: Removing Excess Adhesive: After the overflowing adhesive enters the adhesive receiving groove 3012 and the adhesive discharge groove 3011, press down evenly on the mating position of the screw cone 303 and the recessed part 101, while simultaneously pressing down appropriately on the surrounding area of ​​the lamp panel 301. Discharge the excess adhesive from the adhesive discharge groove 3011 until this position of the lamp panel 301 is tightly fitted with the backplate structure 1, ensuring a flat installation.

[0051] Step 7: Complete the installation of all connection points: Following the operating procedures of Steps 4 to 6 above, sequentially complete the bonding and installation of all connection points between the entire light strip module 3 and the backplate structure 1. Ensure that the accuracy of each installation position meets the assembly requirements to guarantee the installation quality of the entire module.

[0052] Step 8: Cleaning Excess Adhesive: After the overall installation is complete, use a special cleaning tool to carefully clean any excess adhesive from the surface of the lamp board 301 and the adhesive drain groove 3011. Ensure the installation surface is clean and free of adhesive residue, so 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 within the protection scope of the present invention.
