Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for liquid crystal displays, and in particular to a foam rolling device for liquid crystal displays. Background Technology

[0002] A liquid crystal display (LCD) screen is a flat panel device that uses liquid crystal molecules to control light for display. Its core is a fragile glass substrate containing a liquid crystal layer. Before assembly, foam (a strip of adhesive-backed elastic foam material) needs to be attached to the edges of the screen. The main purposes of attaching the foam are to cushion and absorb shock (protecting the fragile glass), seal and prevent dust and moisture intrusion, fill gaps, and distribute stress.

[0003] Traditional processes rely on manual pressing of Teflon molds to press the foam, which has significant drawbacks: 1. Teflon material is hard and brittle, and repeated friction can easily generate debris. If not cleaned thoroughly, it can fall into the display module and cause foreign objects, resulting in poor display quality; 2. Different sizes / models of screens require customized molds, which have poor versatility and increase costs; 3. Relying entirely on the worker's feel for applying force can easily lead to uneven pressing pressure, causing loose adhesion, detachment (insufficient force), or damage to the foam / screen body (excessive force); 4. Manual operation is inefficient and has high labor costs. Worker fatigue further exacerbates quality fluctuations, ultimately leading to a decrease in yield.

[0004] The existing utility model patent with announcement number CN222650294U discloses a clamp-type liquid crystal display foam pressing fixture to replace the Teflon pressing fixture for pressing the foam. However, because it is a hinged design of two clamps, it is necessary to manually hold the other end of the clamps to press the foam when applying pressure, which also has the disadvantages of high labor intensity and low pressing efficiency.

[0031] The liquid crystal display foam rolling device of this application includes a connecting frame, a vertical drive mechanism, a reset connecting seat, and multiple rolling mechanisms. The vertical drive mechanism is mounted on the connecting frame, with its actuating end facing downwards. The reset connecting seat includes a reset connecting shell and a rolling mounting plate, with the reset connecting shell connected to the actuating end of the vertical drive mechanism. The reset connecting shell is a hollow structure with an opening facing downwards. The rolling mounting plate is disposed inside the reset connecting shell, and several elastic pressure structures and several vertical limiting structures are provided between the rolling mounting plate and the reset connecting shell.

At this time, the vertical drive mechanism drives the reset connecting shell to continue to move downward. Through the elastic pressure structure between the two, the rolling mounting plate continues to apply downward pressure, driving the pressure roller to press against the foam. Then, the pressure roller rolls the foam, completing the rolling and bonding action, replacing the traditional manual pressing method, reducing labor intensity and improving processing efficiency. Moreover, the pressure applied by the vertical drive mechanism is more stable than the pressure applied manually, so the foam is subjected to uniform force, improving the foam bonding effect.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0050] like Figures 1 to 10 As shown, this utility model includes a connecting frame 1, a vertical drive mechanism 2, a reset connecting seat 3, and multiple rolling mechanisms 4. The connecting frame 1 is used to mount this application onto an external liquid crystal display screen conveying device and is located above the liquid crystal display screen, so that the rolling mechanisms 4 can roll the foam on the liquid crystal display screen downwards. Of course, the liquid crystal display screen can move along the length direction of the foam under the drive of the external moving device; or, this application can move along the length direction of the foam under the drive of the external moving device (not shown in the figure). It is only necessary to ensure that there is relative movement between this application and the foam on the liquid crystal display screen, so that the foam can be rolled along its length direction. Preferably, this application moves while the foam on the liquid crystal display screen does not move when being rolled. This can ensure the full fit of the rolling, improve the rolling effect, and reduce friction on the liquid crystal display screen.

[0051] In this application, the vertical drive mechanism 2 is mounted on the connecting frame 1, with the actuating end of the vertical drive mechanism 2 facing downwards. The vertical drive mechanism 2 is used to drive the reset connecting seat 3 and multiple rolling mechanisms 4 to move up and down simultaneously.

[0052] The reset connector 3 includes a reset connector shell 31 and a rolling mounting plate 32. The reset connector shell 31 is connected to the actuating end of the vertical drive mechanism 2. The reset connector shell 31 is a hollow structure with an opening facing downwards. The rolling mounting plate 32 is disposed inside the reset connector shell 31. Several elastic pressure structures 33 and several vertical limiting structures 34 are provided between the rolling mounting plate 32 and the reset connector shell 31. When the vertical drive mechanism 2 drives the reset connector shell 31 to move downwards, it can drive the rolling mounting plate 32 to move downwards together. When the vertical drive mechanism 2 drives the reset connector shell 31 to move upwards, it will drive the rolling mounting plate 32 to move upwards together through the vertical limiting structures 34 between the two.

[0053] The rolling mechanism 4 includes a rolling mounting base 41 and a pressure roller 42 located below it. The rolling mounting base 41 is connected to and located below the rolling mounting plate 32, and the pressure roller 42 is rotatably mounted on the rolling mounting base 41. When the rolling mounting plate 32 moves downward, it can drive the pressure roller 42 below to move downward together. When the pressure roller 42 comes into contact with the foam on the LCD screen, in order to achieve the rolling action on the foam, the pressure roller 42 needs to continue to move downward. At this time, the vertical drive mechanism 2 drives the reset connecting shell 31 to continue to move downward. The elastic pressure structure 33 between the two continues to apply downward pressure to the rolling mounting plate 32, driving the pressure roller 42 to press against the foam. Then, because there is relative movement between the two, the pressure roller 42 rolls the foam to complete the rolling bonding action, replacing the traditional manual pressing method, reducing labor intensity and improving processing efficiency. Moreover, the pressure applied by the vertical drive mechanism 2 is more stable than the pressure applied manually, so the foam is subjected to uniform force, which improves the foam bonding effect. The principle of relative movement between the foam and this application has been described above and will not be repeated here; at the same time, the movement of one of the two is driven by an external moving device, which is a well-known technology in this field, and its specific structure will not be described here.

[0054] In this application, the vertical drive mechanism 2 includes a cylinder 21 and a transition connecting seat 22. The cylinder 21 is vertically mounted on the connecting frame 1, and the piston rod of the cylinder 21 is oriented downwards and fixedly connected to the transition connecting seat 22. The transition connecting seat 22 is connected to the reset connecting shell 31. The transition connecting seat 22 serves as a transition connection, facilitating the connection of the cylinder 21 with reset connecting shells 31 of different sizes.

[0055] The elastic pressure structure 33 includes a guide post 331, a guide sleeve 332, and a spring 333. The guide post 331 is fixed to the rolling mounting plate 32; the guide sleeve 332 is fixed to the bottom of the reset connecting shell 31 and is sleeved on the outside of the guide post 331; the spring 333 is sleeved on the outside of the guide sleeve 332 and abuts against the rolling mounting plate 32 and the reset connecting shell 31.

[0056] When the reset connecting shell 31 and the rolling mounting plate 32 move down together, the compression of the spring 333 will not change. Only when the pressure roller 42 abuts against the LCD display foam and continues to move down will the reset connecting shell 31 compress the spring 333. The pressure generated by the spring 333 is transmitted to the pressure roller 42 to apply pressure to the LCD display foam, which meets the requirements of pressing and bonding. In this elastic pressing process, the pressure is applied evenly, slowly and continuously, which can improve the bonding effect of the foam and is also stable, without affecting the pressure intensity on the foam.

[0057] The vertical limiting structure 34 includes a connecting ear 341, a limiting groove 342, and a limiting bolt 343. The connecting ear 341 is fixed to the edge of the rolling mounting plate 32; the limiting groove 342 is vertically arranged and is formed on the side wall of the reset connecting shell 31, corresponding to the position of the connecting ear 341; the head of the limiting bolt 343 is located on the outside of the side wall of the reset connecting shell 31, and the shank of the limiting bolt 343 passes through the limiting groove 342 and the connecting ear 341 and is connected to the limiting nut 344.

[0058] When the pressure roller 42 contacts the LCD display foam and continues to move downward, the reset connecting shell 31 and the rolling mounting plate 32 move relative to each other vertically, and are limited by the vertical limiting structure 34. Importantly, when the rolling is finished, the reset connecting shell 31 drives the rolling mounting plate 32 to move upward. This is achieved by the cooperation of the limiting bolt 343, the limiting groove 342, and the connecting ear 341, which lifts the rolling mounting plate 32 and drives it to rise together. This allows the pressure roller 42 to move upward at the same time, separate from the foam, and continue to roll the next foam, thus meeting the usage requirements.

[0059] In this application, the roll-forming mounting base 41 includes a roll-forming mounting shell 411 and a roll-forming cover plate 412. The roll-forming mounting shell 411 is connected to and located below the roll-forming mounting plate 32 via multiple L-shaped connectors 43. The roll-forming cover plate 412 is mounted above the roll-forming mounting shell 411 and is located between the roll-forming mounting shell 411 and the roll-forming mounting plate 32. The roll-forming cover plate 412 protects the interior of the roll-forming mounting shell 411.

[0060] Multiple L-shaped connectors 43 are symmetrically arranged on both sides of the rolling mounting shell 411 along the axial direction of the pressure roller 42; each L-shaped connector 43 includes two mutually perpendicular connecting parts, one of which is connected to the side wall of the rolling mounting shell 411, and the other connecting part is connected to the rolling mounting plate 32.

[0061] A snap-fit ​​groove 413 is provided on one side wall of the roll-fit mounting housing 411, and a snap-fit ​​strip 414 adapted to the snap-fit ​​groove 413 is provided on the other side wall of the roll-fit mounting housing 411; the snap-fit ​​strip 414 on one of the roll-fit mounting housings 411 snaps into the snap-fit ​​groove 413 on the adjacent roll-fit mounting housing 411.

[0062] Multiple rolling mechanisms 4 are installed below the rolling mounting plate 32. The rolling mounting shells 411 in two adjacent rolling mechanisms 4 are engaged with the locking strips 414 through mutually compatible locking grooves 413. This is used to limit the relative movement between the two rolling mounting shells 411, prevent the rolling effect of the foam from being affected, and improve the rolling stability.

[0063] Connecting rods 44 are hinged to both ends of the pressure roller 42. The connecting rods 44 are vertically arranged, with their top ends connected to the rolling mounting shell 411 and their bottom ends hinged to the pressure roller 42. By providing connecting rods 44, the pressure roller 42 can be detachably installed below the rolling mounting shell 411. The rolling mounting shell 411 is provided with a baffle 45 integrally formed therewith. The baffle 45 is arranged on the outside of the connecting rod 44 along the axial direction of the pressure roller 42. The baffle 45 can block and protect the connecting rod 44, preventing interference with the rotation of the pressure roller 42.

[0064] In use, this application allows for relative movement along its length between itself and the liquid crystal display foam to be rolled. When cylinder 21 moves pressure roller 42 downward, pressure roller 42 first comes into contact with the foam, and then continues to move downward. At this time, spring 333 is compressed, generating pressure on the rolling mounting plate 32, causing pressure roller 42 to press against the foam. Because of the relative movement, pressure roller 42 can roll the foam. After rolling is completed, cylinder 21 moves pressure roller 42 upward. During this process, vertical limiting structure 34 moves rolling mounting plate 32 and pressure roller 42 upward together, facilitating the rolling of the next foam.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
