Description

Technical Field

[0001] The utility model relates to the technical field of UV curing, and particularly relates to a UV curing device for liquid crystal display production. Background Art

[0002] A liquid crystal display is a type of flat panel display that uses a liquid crystal solution between two polarized materials, and when an electric current passes through the liquid, the liquid crystals will rearrange to achieve the purpose of imaging.

[0003] Liquid crystal displays come in various types and have complex structures. Their main components include fluorescent tubes, light guide plates, polarizing plates, filter plates, glass substrates, alignment films, liquid crystal materials, thin film transistors, etc. Since it is mainly a multi-layer plate structure, during production, adhesives are required for bonding between many layers. Among them, UV glue is a very commonly used adhesive, which has good light transmittance, viscosity, and solidifies into a solid state after curing.

[0004] As the name implies, UV glue needs to be cured using ultraviolet light. When bonding between panels, usually a sufficient amount of UV glue is applied first, then the panels are fitted together, and finally placed in a UV light machine for curing. Since the curing time and ultraviolet light intensity required for different types, different thicknesses, and different areas of UV glue are different, manual operation will inevitably cause certain errors, and workers being exposed to ultraviolet light for a long time will cause irreversible damage to their bodies. Therefore, it is necessary to design a UV curing device with a higher degree of automation. Summary of the Utility Model

[0026] Embodiment

[0027] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 5 As shown in the figure, the UV curing device for producing liquid crystal displays in this embodiment includes an operating table 11 for receiving the display screen 12, a bracket 20 provided on the operating table 11, a rolling device 30 provided on the operating table 11, a first driving device for driving the rolling device 30 to move horizontally, and a second driving device for driving the rolling device 30 to move vertically; the rolling device 30 includes a pair of horizontally arranged pressing rollers 31, and a UV lamp tube 32 provided between the pair of pressing rollers 31. Specifically, when in use, the display screen 12 coated with UV glue (the UV glue is between the panel layers inside the display screen 12, not on the surface) but not cured is placed on the operating table 11, and then the second driving device is used to drive the rolling device 30 to move down and press on the display screen 12. Then the UV lamp tube 32 is turned on, and the pressing rollers 31 are driven to roll on the display screen 12 through the first driving device. During the rolling of the pressing rollers 31, the display screen 12 can be squeezed while the UV glue is cured by the UV lamp tube 32. In this way, not only can the panel be more closely attached, but also the curing effect of the UV glue is better, and manual operation is not required, which can better protect the safety of workers.

[0028] In this embodiment, there are a pair of rolling devices 30, and the pair of rolling devices 30 are parallel to each other and at the same height; the first driving device is used to drive the pair of rolling devices 30 to move in opposite directions. Specifically, this can improve the rolling and curing efficiency.

[0029] The rolling device 30 in this embodiment further includes a connecting rod 33 horizontally arranged above the UV lamp tube 32, and a pair of connecting plates 34 respectively fixed at both ends of the connecting rod 33; both ends of the pressing roller 31 are rotatably connected to the connecting plates 34, and both ends of the UV lamp tube 32 are fixedly connected to the connecting plates 34. The bracket 20 includes a plurality of columns 21 arranged on the edge of the operation table 11; the first driving device includes a driving block 41 arranged on the upper side of the connecting rod 33, a screw rod 42 threadedly connected to the driving block 41, a motor 43 connected to the screw rod 42, and a pair of support rods 44 respectively arranged at both ends of the screw rod 42; the axial direction of the screw rod 42 is perpendicular to the axial direction of the pressing roller 31; both ends of the pair of support rods 44 are connected to the columns 21, the motor 43 is connected to one of the support rods 44, and both ends of the screw rod 42 are rotatably connected to the support rods 44; the thread directions on the pair of driving blocks 41 are opposite. Specifically, the movement of the pressing roller 31 and the UV lamp tube 32 is mainly driven by the motor 43 to drive the screw rod 42 to rotate, and then drive the driving block 41 to reciprocate along the screw rod 42, thereby driving the connecting rod 33 and the connecting plate 34 to move. Finally, the connecting plate 34 drives the pressing roller 31 and the UV lamp tube 32 to move. Since the thread directions on the pair of driving blocks 41 are opposite, opposite-threaded threads also need to be provided on the screw rod 42 so as to drive the pair of rolling devices 30 to move in opposite directions.

[0030] The first driving device in this embodiment further includes a fixing block 45 arranged on the connecting rod 33, a sliding hole 46 opened on the fixing block 45, and a sliding rod 47 slidably arranged in the sliding hole 46; both ends of the sliding rod 47 are fixedly connected to the support rods 44. Specifically, through the cooperation of the sliding rod 47 and the fixing block 45, the movement of the rolling device 30 can be made more stable.

[0031] In this embodiment, the support rod 44 is slidably connected to the column 21; the second driving device includes a top rod 22 horizontally disposed at the upper end of the column 21, a wire winder 51 disposed on the top rod 22, a pulling rope 52 connected to the wire winder 51, and a gripping rod 53 disposed at the lower end of the pulling rope 52; the gripping rod 53 is fixedly connected to the sliding rod 47. Specifically, by pulling the gripping rod 53 through the wire winder 51 disposed on the top rod 22, the sliding rod 47 can be pulled up and down, and then the entire rolling device 30 can be pulled up or down. The wire winder 51 mainly includes a wire winding shaft and a motor 43 for driving the wire winding shaft to rotate. By winding the pulling rope 52 around the wire winding shaft, the pulling rope 52 can be contracted and released by rotating the wire winding shaft, thereby achieving the purpose of pulling the rolling device 30. The weight of the rolling device 30 itself can exert a squeezing effect on the display screen 12, so there is no need to apply an additional force to the rolling device 30.

[0032] In this embodiment, a spring 23 is sleeved on the outer wall of the column 21, and the spring 23 is disposed between the operating table 11 and the support rod 44. Specifically, the function of the spring 23 is to prevent the rolling device 30 from exerting too much force on the display screen 12.

[0033] In summary, for the UV curing device for liquid crystal display production in this embodiment, when in use, the display screen 12 coated with UV glue (the UV glue is between the panel layers inside the display screen 12, not on the surface) but not cured is placed on the operating table 11, and then the second driving device is used to drive the rolling device 30 to move down and press on the display screen 12. Then, the UV lamp tube 32 is turned on, and the pressing roller 31 is driven to roll on the display screen 12 through the first driving device. During the rolling process of the pressing roller 31, the display screen 12 can be squeezed while the UV glue is cured by the UV lamp tube 32. This can not only make the panel fit better, but also improve the curing effect of the UV glue, and does not require manual operation, which can better protect the safety of workers.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
