Description

Technical Field

[0001] This invention belongs to the field of television manufacturing technology, and specifically relates to a positioning fixture for fixing double-sided adhesive tape to the F-fold edge of a television back panel. Background Technology

[0002] In television manufacturing, the secure bonding of the back panel and diffuser plate is a crucial step in ensuring product quality. Double-sided adhesive tape, as a core connector, must be precisely applied to the F-fold area of ​​the television's back panel. The quality of this bonding directly impacts the product's stability during transport and its safety in use. If the bonding position is off or the adhesion is not tight, the back panel and diffuser plate can easily separate during transportation, leading to friction and scratches on the display screen and optical films, severely affecting the product's pass rate.

[0003] Currently, the industry mostly uses manual application of double-sided tape, requiring operators to rely on experience to align the F-fold edges for application. However, this method has significant drawbacks: firstly, manual operation makes it difficult to ensure consistency; secondly, manual application is inefficient and cannot meet the needs of large-scale mass production.

[0004] As televisions become thinner, lighter, and higher-definition, the precision requirements for back panel assembly are increasing. Traditional manual pasting methods can no longer meet the demands of high-quality and high-efficiency production. Therefore, there is an urgent need for a specialized fixture that can achieve automatic positioning and precise pasting to improve the consistency and adherence of double-sided tape, reduce defect rates, and increase production efficiency. Summary of the Invention

[0005] In view of the problems mentioned in the background art, the purpose of this invention is to provide a positioning fixture for fixing the F-fold double-sided adhesive tape on the back panel of a television set, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A positioning fixture for fixing double-sided tape with F-folded edge on the back panel of a TV includes an adhesive application component and a moving component. The adhesive application component includes an adhesive applicator for applying the adhesive. The adhesive applicator moves linearly and has an adhesive dispensing station, an adhesive application station, and a clearance station set in its moving stroke. The adhesive application component picks up the double-sided tape with release paper at the adhesive dispensing station. When the moving component moves the back panel close to the adhesive application station, the adhesive application component moves to the clearance station.

[0008] Preferably, the gluing assembly includes a mounting box and a multi-section drive assembly. The mounting box is installed on the output end of the multi-section drive assembly. One side of the mounting box is provided with a glue-dispensing plate for placing double-sided adhesive, and the other side is provided with a release paper clamp. The glue-dispensing plate and the release paper clamp cooperate to hold the release paper.

[0010] Preferably, the moving direction of the output end of the moving component is perpendicular to the moving direction of the output end of the multi-section drive component.

[0011] Preferably, the release paper clip includes a guide groove formed on the mounting box, and a clamping rod is slidably installed in the guide groove. The clamping rod extends and retracts along the guide groove, and can be completely retracted into the guide groove when the clamping rod retracts.

[0012] Preferably, when applying the adhesive, the distance between the side of the double-sided adhesive near the F-fold adhesive surface and the side of the F-fold adhesive surface on the adhesive plate placed on one side of the mounting box is less than the distance between the side of the mounting box near the F-fold adhesive surface and the side of the F-fold adhesive surface.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1

[0026] refer to Figures 1 to 5 The positioning fixture for fixing the double-sided tape of the back panel F of a TV as described in this embodiment includes an adhesive application component 2 and a moving component 3. The adhesive application component 2 includes an adhesive applicator 21 for applying adhesive. The adhesive applicator 21 moves linearly and is provided with an adhesive picking station, an adhesive application station, and a clearance station in its moving stroke. The adhesive application component 21 picks up the double-sided tape with release paper at the adhesive picking station. When the moving component 3 moves the back panel 1 close to the adhesive application station, the adhesive application component 21 moves to the clearance station.

[0027] Preferably, the adhesive application component 2 moves vertically, and the adhesive dispensing station, adhesive application station, and clearance station are distributed from top to bottom. At this time, the double-sided adhesive is set horizontally and is located above the release paper. When applying the adhesive, the adhesive application component 21 supports the double-sided adhesive to keep it horizontal, ensuring the flatness and adhesion of the adhesive. If the double-sided adhesive is tilted or located below the release paper when applying the adhesive, it will be difficult to ensure the consistency of the adhesive application due to gravity.

[0028] It is worth noting that the moving component 3 has an initial position. The moving component 3 loads and unloads materials at the initial position. When the moving component 3 is at the initial position, the back plate 1 and the adhesive application component 21 do not overlap in the horizontal direction.

[0029] Preferably, the moving direction of the output end of the moving component 3 is perpendicular to the moving direction of the output end of the multi-section drive component 212, that is, the output end of the moving component 3 drives the back plate 1 to move horizontally.

[0030] At this time, the adhesive surface of the folded edge F is located on the upper side of the inner wall of the upper horizontal section F.

[0031] The specific process is as follows: First, the glue application component 21 moves to the glue taking station to take glue. After taking glue, the glue application component 21 moves to the clearance station. Then, the moving component 3 drives the F-fold edge 11 of the back plate 1 to the glue application station. The glue application component 21 moves to the glue application station. The moving component 3 drives the F-fold edge 11 to move so that the double-sided tape and release paper are inserted into the F-fold edge 11. The glue application component 21 moves slightly upward to firmly stick the double-sided tape to the glue application surface of the F-fold edge 11.

[0032] The gluing assembly 21 includes a mounting box 211 and a multi-section drive assembly 212. The mounting box 211 is installed on the output end of the multi-section drive assembly 212. A glue-dispensing plate 2131 for placing double-sided adhesive is provided on one side of the mounting box 211. The glue-dispensing plate 2131 extends horizontally, and a release paper clamp 213 is installed on the other side. The glue-dispensing plate 2131 and the release paper clamp 213 cooperate to clamp and fix the release paper.

[0033] The multi-section drive assembly 212 can use common linear drives with controllable stroke, such as linear motors, electric actuators, etc.

[0034] At the glue dispensing station, double-sided tape can be manually placed onto the glue dispensing plate 2131. However, preferably, a glue storage box 22 for storing multiple sets of double-sided tape is provided. The glue storage box 22 is located above the glue application component 21, with its opening facing downwards and onto the side of the release paper clip 213. When dispensing the tape, the glue dispensing plate 2131 is placed close to the release paper, and then the release paper clip 213 is inserted between two sets of release papers. After the glue dispensing plate 2131 and the release paper clip 213 hold the bottom release paper, the multi-section drive component 212 drives the mounting box 211 to move downwards, picking up the bottom set of double-sided tape onto the glue dispensing plate 2131.

[0035] Preferably, the release paper clip 213 includes a guide groove 2134 formed on the mounting box 211, and a clamping rod 2135 is slidably installed in the guide groove 2134. The mounting box 211 is also equipped with a telescopic component 2132, which can be powered by a motor. A connecting rod 2133 is hinged to the telescopic component 2132, and the other end of the connecting rod 2133 is hinged to the clamping rod 2135. The clamping rod 2135 extends and retracts along the guide groove 2134 under the drive of the telescopic component 2132. When the clamping rod 2135 retracts, it can be completely retracted into the guide groove 2134.

[0036] Preferably, the guide groove 2134 gradually descends in the direction close to the glue-dispensing plate 2131.

[0037] Preferably, multiple sets of guide grooves 2134, connecting rods 2133 and clamping rods 2135 are provided, and a linkage rod 2136 is fixedly installed at the output end of the telescopic component 2132. Multiple sets of connecting rods 2133 are hinged to the linkage rod 2136, and multiple sets of clamping rods 2135 simultaneously clamp multiple positions of the release paper, making the clamping more stable.

[0038] When the telescopic component 2132 extends, it drives multiple sets of connecting rods 2133 to approach the double-sided adhesive simultaneously via the linkage rod 2136. The connecting rods 2133 push the clamping rod 2135 to extend along the guide groove 2134 until the end is pressed against the release paper. The clamping rod 2135 and the adhesive plate 2131 firmly clamp the release paper. When the telescopic component 2132 retracts, the clamping rod 2135 retracts and enters the guide groove 2134 to release the release paper.

[0039] When applying the adhesive, the distance between the side of the double-sided tape on the adhesive plate 2131 placed on one side of the mounting box 211 that is close to the adhesive surface of the F-fold 11 is less than the distance between the side of the mounting box 211 that is close to the adhesive surface of the F-fold 11 and the adhesive surface of the F-fold 11.

[0040] It is worth noting that the distance between the adhesive application station and the clearance station, as well as the distance between the adhesive taking station and the adhesive application station, shall not be less than the height of the F-fold, so as to prevent the back panel 1 from being obstructed from moving to the adhesive application station.

[0041] The moving component 3 includes a linear translation module 31 and a suction cup 33 for fixing the back plate 1. A rotating component 32 is installed on the output end of the linear translation module 31, and the suction cup 33 is installed on the output end of the rotating component 32.

[0042] Preferably, the linear translation module 31 uses an electric guide rail, but other linear drive mechanisms can also be used. The rotating component 32 uses a servo motor. The electric guide rail is set horizontally and its length direction is perpendicular to the glue plate 2131. The servo motor is mounted on the slider of the electric guide rail. The output end of the servo motor faces downward and the suction cup 33 is mounted on the output end. The suction cup 33 can controllably adsorb and release the back plate 1.

[0043] Working principle:

[0044] Adhesive Removal: The multi-section drive assembly 212 pushes the mounting box 211 to the adhesive removal station. After the adhesive plate 2131 and the release paper clamp 213 hold the bottom release paper, the multi-section drive assembly 212 drives the mounting box 211 to move down to the clearance station. At this time, the bottom set of double-sided adhesive is picked up onto the adhesive plate 2131. The suction cup 33 adsorbs a set of back plates 1. The rotating assembly 32 drives the suction cup 33 to rotate, so that the F-fold 11 to be pasted is parallel to the adhesive plate 2131.

[0045] Adhesive application: The linear translation module 31 moves the F-fold 11 to the adhesive application station. The multi-section drive assembly 212 pushes the mounting box 211 upward to the adhesive dispensing station and it is located at the opening of the F-fold 11. The linear translation module 31 moves the F-fold 11 closer to the mounting box 211 so that the adhesive plate 2131 and the double-sided adhesive are inserted into the F-fold 11. The multi-section drive assembly 212 continues to push upward to make the double-sided adhesive tightly adhere to the adhesive surface at the top of the F-fold 11. After the adhesive application is completed, the multi-section drive assembly 212 moves the mounting box 211 downward to separate the release paper from the double-sided adhesive. The linear translation module 31 moves the back plate 1 to make way for the mounting box 211. After the mounting box 211 returns to the making-up station, the back plate 1 is driven by the rotating assembly 32 to change sides or return to the initial position. The suction cup 33 releases the material.
