[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] In the related art, since a functional film is provided on the surface of the protective cover plate, the functional film blocks the UV light used for curing, and the UV light cannot penetrate into the protective cover plate and act on the colloid between the protective cover plate and the display module, resulting in incomplete curing of the colloid and loose bonding between the protective cover plate and the display module, affecting the curing efficiency and preparation quality of the display screen.

[0033] Based on the above, refer to Figures 1 to 4In an embodiment of the utility model, a UV curing device is provided, including a curing platform 100 and a curing component 200. The curing platform 100 is used to place a display screen to be cured. A plurality of curing components 200 are provided, each of which includes a light source 210 capable of emitting ultraviolet rays. The curing platform 100 has a curing area 110. The light source 210 irradiates ultraviolet rays to the display screen located in the curing area 110 to cure the display screen.

[0034] Multiple curing components 200 are located above the curing platform 100 and are arranged around the periphery of the curing area 110, wherein two curing components 200 are arranged relative to each other along a first direction to form a first curing group 201, wherein two curing components 200 are arranged relative to each other along a second direction to form a second curing group 202, and the first direction intersects with the second direction, so that the light sources 210 in the first curing group 201 and the second curing group 202 can irradiate ultraviolet rays to the display screen from different directions respectively, and different areas of the colloid between the protective cover plate and the display module are cured at the same time, and the curing efficiency of the display screen is high. In addition, the light source 210 in the first curing group 201 and / or the second curing group 202 irradiates ultraviolet rays from the outside of the curing area 110 to the outer peripheral side of the display screen. The ultraviolet rays emitted by the light source 210 in the first curing group 201 and / or the second curing group 202 irradiate the outside of the display screen, and the light irradiated to the outside of the display screen can avoid the shielding of the colloid by the functional film and directly act on the colloid between the protective cover plate and the display module, so that the colloid quickly undergoes a cross-linking reaction and solidifies. Therefore, the colloid in the display screen can be thoroughly cured, thereby improving the curing degree of the display screen, and the protective cover plate is stably bonded to the display panel, thereby improving the preparation quality of the display screen.

[0035] In one embodiment, the light source 210 in the first curing group 201 and / or the second curing group 202 is flush with the curing platform 100, so that the light emitted by the light source 210 can directly and horizontally irradiate the outer periphery of the display screen, so that the ultraviolet rays are concentrated on the outer periphery of the display screen.

[0036] Alternatively, in another embodiment, the light source 210 of the first curing group 201 and / or the second curing group 202 is higher than the curing platform 100 and tilted toward the curing platform 100. Since the light source 210 needs to irradiate toward the display screen located in the display area, and the curing assembly 200 is located at the periphery of the curing area 110, the ultraviolet rays emitted by the light sources 210 in the first curing group 201 and / or the second curing group 202 are directed toward the curing area 110 and tilted downward; in this way, among the ultraviolet rays emitted by the light sources 210 in the first curing group 201 and / or the second curing group 202, part of the light is irradiated to the top of the display screen, and part of the light is irradiated to the outside of the display screen, and the light irradiated to the outside of the display screen can avoid the shielding of the functional film to the colloid and directly act on the colloid between the protective cover and the display module.

[0037] It should be noted that multiple first curing groups 201 and second curing groups 202 can be set, and multiple curing groups can simultaneously irradiate ultraviolet rays to the display screen, which can further improve the curing efficiency of the display screen; further, the light sources 210 located in different first curing groups 201 have different irradiation angles to increase the irradiation area of ​​the first curing group 201 and improve the curing efficiency of the display screen. Similarly, the light sources 210 located in different second curing groups 202 have different irradiation angles to increase the irradiation area of ​​the second curing group 202 and improve the curing efficiency of the display screen.

[0038] One of the first curing group 201 and the second curing group 202 can irradiate ultraviolet rays to the outside of the display screen to improve the curing efficiency of the display screen. Exemplarily, the light source 210 in the first curing group 201 is tilted and irradiates the top and side of the display screen, the light source 210 in the second curing group 202 irradiates the top of the display screen, and the light source 210 in the second curing group 202 irradiates from the side of the display screen along the first direction, and the ultraviolet rays are not blocked by the functional film and directly act on the colloid, so that the colloid in the display screen can be completely cured; or, the light sources 210 in the first curing group 201 and the second curing group 202 are both tilted, the light source 210 in the first curing group 201 irradiates from the side of the display screen along the first direction, and the light source 210 in the second curing group 202 irradiates from the side of the display screen along the second direction, and the colloid can be irradiated by ultraviolet rays from different directions at the same time, which can improve the curing efficiency of the display screen.

[0039] It should be noted that, since the first curing group 201 and / or the second curing group 202 can irradiate from the side of the display screen, the UV curing device in the present invention is suitable for curing curved display screens, that is, the ultraviolet rays irradiated toward the side of the display screen can just act on the curved corner area at the edge of the curved display screen, thereby achieving curing of the curved corner area of ​​the curved display screen.

[0040] It is understandable that a reflective component may be provided in the UV curing device to change the optical path of the ultraviolet light so that the ultraviolet light emitted by the first curing group 201 and the second curing group 202 is irradiated toward the display screen from the side of the display screen to the maximum extent, so as to improve the curing efficiency of the display screen. The reflective component may be composed of one or more reflective sheets, and the one or more reflective sheets cooperate to change the irradiation direction of the ultraviolet light by reflecting light, so that the ultraviolet light is irradiated to the side of the display screen in a more concentrated manner.

[0041] In addition, the wavelengths of ultraviolet rays emitted by different curing components 200 in the same first curing group 201 are different, or the wavelengths of ultraviolet rays emitted by the curing components 200 in the first curing group 201 and the second curing group 202 are different. Through the combination of ultraviolet rays of different wavelengths, the areas affected by ultraviolet light waves of different wavelengths are coupled with each other, and different areas of the colloid can receive ultraviolet light waves, and the curing of the colloid is more uniform. Exemplarily, the wavelength of ultraviolet rays can be set to two or more of 365nm, 395nm, and 405nm.

[0042] The UV curing device also includes a conveying component 300, and the conveying component 300 includes a conveying belt 310. The conveying belt 310 is used to convey the display screen along a first direction, and the top surface of the conveying belt 310 forms a curing platform 100; thus, through the conveying component 300 to convey the display screen, after the previous display screen is cured, the conveying belt 310 drives the display screen to move, the previous display screen is away from the curing area 110, and the next display screen enters the curing area 110 for curing, thereby realizing the automated preparation of the display screen, without the need for operators to repeatedly take and place the display screen in the curing area 110, and the curing efficiency of the display screen is high.

[0043] The conveyor assembly 300 further includes a driving element for driving the conveyor belt 310 to move, and the driving element is connected to the conveyor belt 310 and drives the conveyor belt 310 to move. Exemplarily, the driving element includes two transmission rollers spaced apart along a first direction, the conveyor belt 310 is wound around the two transmission rollers, and the upper part of the conveyor belt 310 is in a horizontal state, the horizontal part of the conveyor belt 310 forms a curing platform 100, and a plurality of display screens are spaced apart and placed on the conveyor belt 310 along the first direction. When the transmission rollers rotate, the conveyor belt 310 moves along the first direction, and the display screens move along the first direction synchronously.

[0044] The UV curing device also includes a curing chamber 400, wherein a curing cavity 410 is provided inside the curing chamber 400, wherein the curing assembly 200 is disposed inside the curing cavity 410, and the curing area 110 is located below the curing cavity 410. When the display screen is located in the curing cavity 410, it is irradiated by the curing assembly 200 and cured. The curing chamber 400 can isolate part of the air from entering the curing cavity 410, thereby preventing air from entering the display screen and forming bubbles. In addition, the driving element is used to drive the conveyor belt 310 to move along the first direction, so that the display screen enters the curing cavity 410 for curing, and moves out of the curing cavity 410 after curing is completed.

[0045] In one embodiment, the driving element drives the conveyor belt 310 to move back and forth along the first direction, so that the conveyor belt 310 can drive the display screen to repeatedly enter the curing chamber 410, and the curing component 200 can irradiate the display screen multiple times, so that the colloid in the display screen is cured more thoroughly. In another embodiment, the UV curing device includes a plurality of curing chambers 410 arranged along the first direction, and each curing chamber 410 is provided with a curing component 200. The driving element is used to drive the conveyor belt 310 to move along the first direction so that the display screen enters different curing chambers 410 in turn, and the curing components 200 in different curing chambers 410 irradiate ultraviolet rays to the display screen in turn, and the display screen can undergo multiple curing, so that the colloid in the display screen is cured more thoroughly.

[0046] The UV curing equipment also includes a plurality of brackets 500, which are used to install the curing components 200. The plurality of brackets 500 are arranged around the periphery of the curing area 110, and the brackets 500 extend vertically. At least one curing component 200 is detachably connected to each bracket 500, and the curing component 200 is located on the side of the bracket 500 facing the curing area 110. Since the curing component 200 is detachably connected to the bracket 500, the later maintenance and replacement of the curing component 200 are facilitated. The detachable connection method between the curing component 200 and the bracket 500 is not limited to threaded connection, hanging, clamping, etc.

[0047] It is understandable that the bracket 500 extends vertically, and a plurality of mounting positions for the curing assembly 200 to be detachably connected are arranged vertically. The curing assembly 200 can be selectively installed at different mounting positions, so that the installation height of the curing assembly 200 on the bracket 500 is adjustable. By changing the height of the curing assembly 200, the curing area 110 of the ultraviolet light and the curing intensity can be adjusted, making the use of the UV curing device more flexible. Exemplarily, the bracket 500 is vertically provided with a plurality of mounting holes arranged at intervals, and the threaded fasteners are threadedly connected to the curing assembly 200 through the mounting holes, and the curing assembly 200 is fixed to the bracket 500. When the threaded fasteners are inserted into different mounting holes, the curing assembly 200 can be installed at different heights of the bracket 500.

[0048] In addition, the UV curing device also includes a frame 600, the conveying assembly 300 and the curing chamber 400 are both installed on the top of the frame 600, the curing chamber 410 is located above the conveying belt 310, and the bracket 500 is erected on the inner wall of the curing chamber 400, and the bracket 500 is located above the conveying belt 310; on the one hand, the inner wall of the curing chamber 400 provides an installation base for the conveying assembly 300, and on the other hand, after the bracket 500 is erected on the inner wall of the curing chamber 400, there is a certain distance between it and the conveying belt 310, which can avoid the display screen from being transported along the first direction. It can be understood that the curing chamber 400 should be provided with an inlet and an outlet on both sides opposite to each other in the first direction, so that the display screen can enter the curing chamber 410 from the inlet and move out of the curing chamber 410 through the outlet after curing is completed.

[0049] In one embodiment, the curing component 200 includes a shell 220 and an adjusting member, the light source 210 is installed on the shell 220, and the end of the shell 220 is rotatably connected to the bracket 500. The adjusting member is used to lock the shell 220 and the bracket 500, or unlock the shell 220 and the bracket 500 so that the shell 220 can rotate relative to the bracket 500. When the shell 220 rotates relative to the bracket 500, the direction of the ultraviolet light emitted by the light source 210 can be changed to adjust the irradiation area and irradiation angle of the ultraviolet light, etc., and can adapt to the curing requirements of different types of display screens.

[0050] Exemplarily, the housing 220 of each curing assembly 200 is installed through two housings 220, and the two ends of the housing 220 are rotatably connected to the two brackets 500, for example, a rotating shaft is provided at the end of the housing 220, and an axial hole is provided on the bracket 500, and the rotating shaft is passed through the axial hole and can rotate relative to the bracket 500. The adjustment member is configured as a threaded fastener, and the threaded fastener is threadedly connected to the housing 220 and the bracket 500. When the threaded fastener is tightened, the threaded fastener locks the housing 220 and the bracket 500, and the position of the curing assembly 200 relative to the bracket 500 is fixed. When the threaded fastener is loosened, the locking of the housing 220 and the bracket 500 is released, and the housing 220 can rotate relative to the bracket 500, and the angle at which the curing assembly 200 emits ultraviolet rays can be changed. The light source 210 can be installed inside the shell 220, or installed outside the shell 220. The light source 210 is configured as an LED lamp. Taking the case where the light source 210 is configured inside the shell 220 as an example, the side of the shell 220 facing the curing area 110 has a light-transmitting function, so that the light emitted by the light source 210 can be emitted outward through the shell 220; or a lens is provided on the side of the shell 220 facing the curing area 110, and the light emitted by the light source 210 is emitted outward through the lens, which can improve the light output efficiency of the light source 210 and the uniformity of ultraviolet irradiation to the display screen.

[0051] In another embodiment, the bracket 500 includes a plurality of hanging grooves 510 distributed at intervals in the vertical direction. The hanging grooves 510 are arranged on the side of the bracket 500 facing the curing area 110. The hanging grooves 510 are inclined from bottom to top toward the curing area 110. An opening 520 is formed at one end of the hanging groove 510 facing the curing area 110. The shell 220 is hung in the hanging groove 510 through the opening 520. On the one hand, since the hanging grooves 510 are inclined upward, after the shell 220 is hung in the hanging groove 510, under the action of gravity, it can always be close to the bottom of the hanging groove 510 and maintain a stable position. On the other hand, when the height of the curing assembly 200 needs to be changed, the shell 220 can be lifted downward to separate the shell 220 from a hanging groove 510 through the opening 520, and the shell 220 can be hung in the hanging groove 510 of the corresponding height according to the needs, which is more convenient to operate.

[0052] In addition, a hook that matches the hanging groove 510 may be provided at the end of the shell 220, or a pin may be provided at the end of the shell 220, and both ends of the shell 220 are respectively hung on two spaced brackets 500.

[0053] Furthermore, the opening 520 is arranged on one side of the hanging groove 510 along the hanging direction, and the hanging groove 510 passes through along the locking direction, and the hanging direction is perpendicular to the locking direction. The curing assembly 200 also includes a locking member 230, which passes through the hanging groove 510 along the locking direction, and one end of the locking member is threadedly connected to the shell 220 to lock the shell 220 to the bracket 500, or to unlock the shell 220 so that the curing assembly 200 can be hung in different hanging grooves 510 or the curing assembly 200 can be rotated in the hanging groove 510. Specifically, the locking member 230 is configured as a threaded fastener, such as a bolt. The locking member 230 passes through the hanging groove 510 and is threadedly connected to the shell 220. When the locking member 230 is locked, the nut of the locking member 230 abuts against the bracket 500. At this time, the shell 220 is locked to the bracket 500. When the locking member 230 is loosened, the lock between the shell 220 and the bracket 500 is released, and the shell 220 can be rotated relative to the bracket 500 to change the angle of ultraviolet rays emitted by the curing component 200. When the locking member 230 is withdrawn from the shell 220, the shell 220 can be detached from the hanging groove 510. At this time, the shell 220 can be installed in a different hanging groove 510 again to change the height of the curing component 200.

[0054] It can be understood that both ends of the shell 220 are locked to the bracket 500 through the locking piece 230. A handle can also be set at the end of the locking piece 230 away from the shell 220. The handle can be held by the operator to facilitate the rotation of the locking piece 230, making the adjustment of the curing assembly 200 more convenient.

[0055] The UV curing device further includes an auxiliary curing element 700, which is disposed above the curing area 110 and is used to emit ultraviolet rays downward to irradiate the display screen. The auxiliary curing element 700 can be configured as an LED surface lamp, and the ultraviolet rays emitted by the auxiliary curing element 700 irradiate the top surface of the display screen. The auxiliary curing element 700 is used in combination with the curing component 200, and the auxiliary curing component 200 irradiates the display screen, which can improve the curing efficiency of the display screen and meet the curing requirements of different types of display screens.
