Description

Technical Field

[0001] This utility model relates to the field of television screen assembly technology, and in particular to a material bonding roller pressing device. Background Technology

[0002] During the production and assembly of television sets, after the screen and back panel are initially bonded together using adhesive, a rolling process is required to remove air bubbles between the bonding layers. This ensures a tight and secure bond, thereby improving product yield and lifespan. Currently, the common practice in the industry is to perform manual or simple mechanical rolling directly on the conveyor belt of the production line.

[0003] First, direct operation on flexible or gapped conveyor belts results in an unstable working surface, making it difficult to provide uniform and flat support. This can easily lead to stress concentration due to uneven force distribution when the screen is under pressure, potentially causing microcracks or damage, posing a high risk to product quality. Second, conveyor belts themselves typically lack precise positioning capabilities, and material positioning may deviate during transport and residence, resulting in inaccurate roller pressing positions and affecting the bonding effect. Third, existing equipment has limited automation, often requiring manual intervention for positioning or single-machine operation, leading to low efficiency. Furthermore, it typically only presses one edge of the screen at a time, resulting in a slow production cycle and failing to meet the high efficiency and consistency requirements of modern large-scale production.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] In the specific implementation process, the two transmission components 22 arranged opposite to each other operate synchronously under the drive of the transmission shaft 212, and synchronously drive the two screw seats 224 to make the two sides of the lifting frame 23 move synchronously, ensuring that the support rod 24 on the lifting frame 23 moves smoothly in the vertical direction.

[0033] In this embodiment, as Figure 5 As shown, the first correction assembly 31 includes a crossbeam 311 and a first roller 312 rotatably mounted thereon, and the second correction assembly 32 includes a longitudinal beam 321 and a second roller 322 rotatably mounted thereon. The crossbeam 311 and the longitudinal beam 321 are respectively connected to a third power device 33 and a fourth power device 34. The crossbeam 311 and the longitudinal beam 321 are arranged perpendicularly. Multiple first rollers 312 are arranged along the length of the crossbeam 311, and multiple second rollers 322 are arranged along the length of the longitudinal beam 321. The rotation axes of the first roller 312 and the second roller 322 are both arranged vertically.

[0034] The first roller 312 and the second roller 322, which are set on the crossbeam 311 and the longitudinal beam 321, abut against the edge of the screen and adjust the horizontal position of the screen; the first roller 312 and the second roller 322 are set vertically in the axis to avoid friction damage between the edge of the back panel and the roller during the adjustment process.

The third power unit 33 includes a first cylinder 331 and a first slide rail 332, and the fourth power unit 34 includes a second cylinder 341 and a second slide rail 342. The first cylinder 331 and the second cylinder 341 are respectively connected to the crossbeam 311 and the longitudinal beam 321. The crossbeam 311 and the longitudinal beam 321 are slidably connected to the third support 35 through the first slide rail 332 and the second slide rail 342, respectively.

[0036] The first cylinder 331 is connected to the middle of the crossbeam 311. Two first slide rails 332 are symmetrically arranged on both sides of the first cylinder 331 to ensure the smooth driving of the crossbeam 311. Similarly, two second slide rails 342 are also symmetrically arranged on both sides of the second cylinder 341 to ensure the smooth driving of the longitudinal beam 321.

[0038] In the specific implementation process, the screen is first supported by the lifting mechanism 2. Then, the third power device 33 and the fourth power device 34 drive the crossbeam 311 and the longitudinal beam 321 to move towards the screen, adjusting the position of the screen on the lifting mechanism 2. At this time, the support plate 36 on the crossbeam 311 and the longitudinal beam 321 is located below the screen. Then, the lifting mechanism 2 is retracted so that the back plate falls onto the pad 362 in the positioning groove 361 on the support plate 36. This completes the fixation of the screen and ensures the stability of the screen position during the rolling process.

[0039] In this embodiment, as Figure 6 and Figure 7 As shown, the roller pressing assembly 43 includes a vertically arranged third linear module 431 and a horizontally arranged fourth linear module 432.
