Description

Technical Field

[0001] This application relates to the field of capacitive touchscreen manufacturing technology, and in particular to a UV machine for processing capacitive touchscreens. Background Technology

[0002] In the production process of capacitive touch screens, the glass substrate and ITO film are usually bonded together using UV adhesive, and then the UV adhesive is cured by a UV light machine after bonding.

[0003] Currently, conventional UV adhesives primarily work by moving a movable UV lamp module along a set path to cover the entire glass substrate, thus completing the curing process. While this method offers low energy consumption and high adjustability, it has a long curing time and is inefficient for mass production, failing to meet production volume requirements.

[0004] The solution of using multiple fixed UV lamp modules for overall irradiation has the following drawbacks: in order to avoid the UV lamp modules touching the product and causing damage or displacement to the product to be cured, the distance between the UV lamp module placement position and the product placement position is large, resulting in a large power of the UV lamp modules required. Moreover, although it can be mass-produced, the curing effect on the edges or sides of the product to be cured is poor, ultimately resulting in insufficient curing effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a UV machine for processing capacitive touch screens, which solves the problem of insufficient curing efficiency or insufficient curing effect of UV adhesive on the edges and sides of existing UV machines.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a UV machine for processing capacitive touch screens, comprising a frame, and a working space for placing products to be cured within the frame, including:

[0007] The conveying mechanism includes a conveying platform and a telescopic platform. The telescopic platform is set on the conveying platform. The conveying platform can move on the frame in a first direction to convey the product to be cured placed on the telescopic platform from outside the frame into the working space.

[0008] The pressure irradiation mechanism is located at the top of the workspace. The pressure irradiation mechanism moves vertically and pushes the telescopic platform to extend and retract. After the pressure is completed, the pressure irradiation mechanism and the conveying platform enclose a sealed irradiation cavity, thereby performing UV curing on the product to be cured in the irradiation cavity.

[0009] In one embodiment, the telescopic platform includes a fixed plate and a telescopic plate. The fixed plate is disposed on the conveying platform, and a telescopic assembly is provided between the telescopic plate and the conveying platform. The telescopic assembly causes the telescopic plate to move closer to or further away from the conveying platform in the vertical direction.

[0010] The telescopic plate has a pressure column on the side away from the fixed plate for contacting the downward irradiation mechanism. The pressure columns are distributed vertically, and the highest point of the product to be cured is lower than the highest point of the pressure column.

[0011] In one embodiment, the telescopic assembly includes a guide post and an adjusting spring. The guide post is disposed on a fixed plate, and the two ends of the adjusting spring are respectively connected to the fixed plate and the telescopic plate. A guide groove is provided on the side of the telescopic plate near the fixed plate corresponding to the guide post.

[0012] In one embodiment, the guide post includes a fixed part and a telescopic part. The fixed part is connected to a fixed plate, and the telescopic part extends vertically from the top of the fixed part and extends into the guide groove. When the telescopic plate is pressed, the guide groove pushes the telescopic part back into the fixed part.

[0013] In one embodiment, the pressure post and the telescopic plate are detachably connected.

[0014] In one embodiment, the surface of the telescopic plate is provided with quartz glass, which is used to hold the product to be cured, and the side of the quartz glass away from the product to be cured is coated with a reflective coating.

[0015] In one embodiment, the conveying platform is provided with a support wall around the fixed plate, and a lifting cylinder is provided between the fixed plate and the conveying platform. The lifting cylinder causes the fixed plate to move up and down along the inner side of the support wall.

[0016] In one embodiment, the downward irradiation mechanism includes a cover and an ultraviolet lamp module. The cover is provided with a first stepped groove and a second stepped groove. The first stepped groove is provided corresponding to the support wall. The second stepped groove and the conveying platform together form an irradiation cavity. The ultraviolet lamp module is disposed in the second stepped groove.

[0017] In one embodiment, a supplementary light assembly is provided on the side of the support wall near the telescopic platform, and the height of the supplementary light assembly is at least level with the lowest point of the product to be cured after the telescopic platform is lowered.

[0018] In one embodiment, the supplementary light assembly includes a telescopic rod, a mounting plate, and a supplementary light source. The two ends of the telescopic rod are connected to the support wall and the mounting plate, respectively, and the supplementary light source is located on the side of the mounting plate away from the support wall.

[0019] The beneficial effects of this invention are as follows: Conventional UV machines use a moving path to ensure that the area irradiated by ultraviolet light can cover the entire product to be cured. Although this method can guarantee the curing effect, the overall curing efficiency is low.

[0020] This invention utilizes a downward irradiation mechanism and a conveying platform to form an irradiation cavity, allowing products to be cured in batches within the cavity, ensuring curing efficiency. Simultaneously, the sealed irradiation cavity prevents ultraviolet light leakage, guaranteeing operator safety.

[0021] Meanwhile, since the products to be cured have different specifications, in order to avoid the distance between the pressure irradiation mechanism and the products to be cured being too large or too small due to different specifications, this utility model is equipped with a telescopic platform on the conveying platform. The telescopic platform is compressed by force during the pressure irradiation mechanism, dynamically adjusting the distance between the pressure irradiation mechanism and the products to be cured. This ensures the ultraviolet irradiation area while preventing the products to be cured from directly touching the pressure irradiation mechanism, ensuring that the products to be cured do not shift or crack. This effectively improves the adaptability of this utility model. Attached Figure Description

[0030] Please refer to Figures 1 to 3 A UV curing machine for capacitive touchscreens includes a frame with a workspace for placing products 3 to be cured within the frame.

[0031] The conveying mechanism 1 includes a conveying platform 11 and a telescopic platform 12. The telescopic platform 12 is mounted on the conveying platform 11. The conveying platform 11 can move along the first direction on the frame to convey the product 3 to be cured placed on the telescopic platform 12 from outside the frame into the working space. The pressing irradiation mechanism 2 is mounted on the top of the working space. The pressing irradiation mechanism 2 moves vertically and pushes the telescopic platform 12 to extend and retract. After pressing, the pressing irradiation mechanism 2 and the conveying platform 11 enclose a sealed irradiation cavity, thereby performing UV curing on the product 3 to be cured in the irradiation cavity.

[0032] The telescopic platform 12 allows the product 3 to be cured to move vertically. However, conventional telescopic structures can only press the telescopic platform 12 down, failing to guarantee the distance between the product 3 placed on the telescopic platform 12 and the pressing irradiation mechanism 2. Therefore, the irradiation coverage area of ​​the UV lamp module 22 cannot be guaranteed to meet the requirements. Therefore, in this embodiment, the telescopic platform 12 includes a fixed plate 121 and a telescopic plate 122. The fixed plate 121 is mounted on the conveying platform 11, and a telescopic assembly 123 is provided between the telescopic plate 122 and the conveying platform 11. The telescopic assembly 123 allows the telescopic plate 122 to move vertically closer to or further away from the conveying platform 11. A pressure post 124 for contacting the pressing irradiation mechanism 2 is provided on the side of the telescopic plate 122 away from the fixed plate 121. The pressure posts 124 are distributed vertically, and the highest point of the product 3 to be cured is lower than the highest point of the pressure post 124. The distance between the final pressing irradiation mechanism 2 and the telescopic platform 12 is adjusted by the height of the pressing column 124, thereby controlling the distance between the product to be cured 3 and the pressing irradiation mechanism 2, ensuring that the ultraviolet lamp module 22 can fully irradiate the product to be cured 3 during irradiation, thus ensuring the effect.

[0033] Specifically, a pressure plate can be installed on the top of the pressure column 124 to prevent damage caused by the small contact area between the pressure irradiation mechanism 2 and the pressure column 124, thereby improving the overall service life of the device.

[0034] Preferably, the pressure column 124 adopts an adjustable height telescopic column structure, and height scale is etched on the pressure column 124 so that the operator can obtain the height difference between the highest point of the product to be cured 3 and the highest point of the pressure column 124, thereby making quick adjustments, improving the degree of standardization, and thus improving work efficiency.

[0035] Preferably, the pressure columns 124 are located at the four corners or the center of the telescopic plate 122, so as to uniformly guide the pressure of the downward irradiation machine to the telescopic plate 122.

[0036] After the pressure column 124 is installed, the distance between the telescopic plate 122 and the pressure irradiation machine remains constant during the pressing process. However, since the telescopic plate 122 is passively pressed down, if there is no guiding constraint, the telescopic plate 122 may deviate in the horizontal direction, causing it to exceed the range of the fixed plate 121, resulting in damage to the product 3 to be cured or damage to the equipment. Therefore, the telescopic assembly 123 includes a guide column 1231 and an adjusting spring 1232. The guide column 1231 is set on the fixed plate 121, and the two ends of the adjusting spring 1232 are respectively connected to the fixed plate 121 and the telescopic plate 122. The side of the telescopic plate 122 closest to the fixed plate 121 is provided with a guide groove 1221 corresponding to the guide column 1231. Through the cooperation of the guide column 1231 and the guide groove 1221, it is ensured that the telescopic plate 122 can only move in the vertical direction.

[0037] Preferably, the guide post 1231 includes a fixed part and a telescopic part. The fixed part is connected to the fixed plate 121, and the telescopic part extends vertically from the top of the fixed part and into the guide groove 1221. When the telescopic plate 122 is pressed, the guide groove 1221 pushes the telescopic part back into the fixed part. That is, the guide post 1231 adopts a two-stage structure. The telescopic part is set inside the fixed part and extends into the guide groove 1221 from the top of the fixed part through a spring or other structure. When the telescopic plate 122 is not pressed, it is laterally restricted, reducing the lateral force on the telescopic plate 122 during the placement of the product 3 to be cured, which would cause the telescopic plate 122 to vibrate. This prevents the product 3 to be cured from separating due to vibration and ensures the curing effect. At the same time, it can prevent the adjusting spring 1232 from being subjected to excessive horizontal force, which would cause torsional deformation and ensure the overall service life. Furthermore, the top of the telescopic part is connected to the guide groove 1221.

[0038] In this embodiment, the pressure column 124 and the telescopic plate 122 are detachably connected. This arrangement makes it convenient for operators to replace or adjust the pressure column 124, thereby adapting to products 3 of different sizes and specifications to be cured, and further improving the overall adaptability.

[0039] In this embodiment, a quartz glass 1222 is provided on the surface of the telescopic plate 122. The quartz glass 1222 is used to place the product 3 to be cured. A reflective coating is applied to the side of the quartz glass 1222 away from the product 3 to be cured. The quartz glass 1222 with the reflective coating can reflect ultraviolet rays, allowing the ultraviolet rays to be reflected to the side or bottom of the product 3 to be cured from the part where the product 3 is not placed. This improves the utilization efficiency of ultraviolet rays in the sealed irradiation cavity and ensures the curing effect.

[0040] The telescopic plate 122 enables the UV machine for processing capacitive touch screens to passively adjust the distance between the products to be cured 3 and the products to be cured 3. However, when the thickness or size of the product to be cured 3 is too large, a support wall 111 is set around the fixed plate 121 on the conveying platform 11. A lifting cylinder 125 is provided between the fixed plate 121 and the conveying platform 11. The lifting cylinder 125 causes the fixed plate 121 to move up and down along the inner side of the support wall 111, thereby actively adjusting the size of the irradiation cavity, thereby changing the size of the product to be cured 3 that the irradiation cavity can accommodate, and improving the overall adaptability.

[0041] In order to ensure that the irradiation cavity can be adapted to the pressure columns 124 of different heights and thus ensure the sealing effect, in this embodiment, the pressure irradiation mechanism 2 includes a cover 21 and an ultraviolet lamp module 22. The cover 21 is provided with a first stepped groove 211 and a second stepped groove 212. The first stepped groove 211 is provided corresponding to the support wall 111. The second stepped groove 212 and the conveying platform 11 enclose the irradiation cavity. The ultraviolet lamp module 22 is disposed in the second stepped groove 212.

[0042] Preferably, the support wall 111 is also provided with a supplementary light group 13 on the side near the telescopic platform 12. The height of the supplementary light group 13 is at least level with the lowest point of the product 3 to be cured after the telescopic platform 12 is lowered. That is, the supplementary light group 13 provides supplementary irradiation to the side of the product 3 to be cured, thereby ensuring the curing effect. At the same time, the supplementary light group 13 can cooperate with the quartz glass 1222 to conduct ultraviolet light from the side of the product 3 to be cured to the bottom of the product 3 to be cured, so that the UV machine for capacitive touch screen processing can meet the requirement of simultaneous double-sided curing of the product 3 to be cured, further improving the overall adaptability.

[0043] In this embodiment, the supplementary light assembly 13 includes a telescopic rod 131, a mounting plate 132, and a supplementary light source 133. The two ends of the telescopic rod 131 are connected to the support wall 111 and the mounting plate 132, respectively. The supplementary light source 133 is located on the side of the mounting plate 132 away from the support wall 111. The telescopic rod 131 can adjust the distance between the mounting plate 132 and the support wall 111, thereby controlling the illumination range of the supplementary light source 133 and further improving the overall adjustability and adaptability.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
