[0002] In the field of curing technology in 3D printing, most current methods use direct UV light. However, this conventional UV light source layout has significant drawbacks. Because the UV light source emits light radially, its irradiation range is relatively narrow, which cannot effectively cover a large area to be cured. This greatly limits the curing efficiency. At the same time, due to the limited irradiation range, the curing reaction cannot proceed uniformly and fully, thus affecting the curing quality. Utility Model Content

[0003] The main purpose of this invention is to provide a UV curing light source and curing chamber, which aims to improve the quality and efficiency of UV curing.

[0004] To achieve the above objectives, this utility model proposes a UV curing light source, comprising:

[0005] support;

[0006] The light strip is mounted on the bracket;

[0007] A lens is disposed on the side of the light strip away from the bracket and connected to the bracket, wherein the side of the lens facing the light strip is a flat surface and the side of the lens away from the light strip is a convex arc surface.

[0013] In one embodiment, a limiting groove is provided on the base plate, the limiting groove extends along the length of the light strip to both ends of the base plate, and an avoidance groove is provided on the side of the support plate facing the light strip. The avoidance groove is opposite to the limiting groove and extends along the length of the light strip to both ends of the support plate. The avoidance groove and the limiting groove together form the installation channel.

[0014] In one embodiment, the limiting plate and the support plate are detachably connected.

[0015] In one embodiment, at least two limiting plates are provided, and the at least two limiting plates are correspondingly provided at both ends of the lens in the length direction.

[0016] In one embodiment, the support plate is detachably connected to the base plate; and / or, the light strip is detachably connected to the base plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] To improve the efficiency and quality of UV curing, this technical solution proposes a UV curing light source, including: a bracket 100; a lamp strip 200 disposed on the bracket 100; and a lens 300 disposed on the side of the lamp strip 200 away from the bracket 100 and connected to the bracket 100. The side of the lens 300 facing the lamp strip 200 is a flat surface, and the side of the lens 300 away from the lamp strip 200 is a convex arc surface.

[0032] Specifically, such as Figures 1 to 4 In this embodiment, the bracket 100 is made of aluminum alloy, and the light strip 200 is a UV-band LED light, which is set as a long strip. The light strip 200 is mounted on the bracket 100. A lens 300 is set on the side of the light strip 200 away from the bracket 100. The lens 300 is semi-cylindrical in shape. The side of the lens 300 facing the light strip 200 is flat, and the side of the lens 300 away from the light strip 200 is convex. The light from the light strip 200 can be taken into the lens 300 and dispersed from the convex surface after being refracted by the lens 300. With this setting, the light from the light strip 200 can be focused after passing through the lens 300, eliminating the divergence of the light emitted by the light strip 200, making the light intensity more uniform and higher, thereby improving the curing efficiency and curing quality.

[0033] like Figure 1 and Figure 2 In one embodiment of the present invention, the bracket 100 includes: a base plate 110, on which the light strip 200 is disposed; a support plate 120, on which the light strip 200 is disposed on the side away from the base plate 110, the support plate 120 is provided with a window 121, the window 121 is arranged opposite to the light strip 200, and a lens 300 is disposed on which the support plate 120 is disposed on the side away from the light strip 200 and is arranged opposite to the window 121. The base plate 110 is rectangular and is used to mount the light strip 200. A support plate 120 is located on the side of the light strip 200 away from the base plate 110, and works with the base plate 110 to clamp the light strip 200, ensuring reliable fixation. Additionally, a window 121 is provided on the support plate 120, the shape and size of which are adapted to the light strip 200 to ensure that the light emitted by the light strip 200 can be emitted. A lens 300 is located on the side of the support plate 120 away from the light strip 200, facing the window 121. This ensures that all the light emitted by the light strip 200 can enter the lens 300, guaranteeing a focused UV light effect. In this design, the structural design of the bracket 100 ensures accurate alignment between the lens 300 and the light strip 200, improving curing efficiency and ensuring uniformity and consistency of curing quality.

[0034] like Figure 1 and Figure 2In one embodiment of this utility model, the bracket 100 further includes a limiting plate 130. The limiting plate 130 is attached to the side of the lens 300 facing away from the support plate 120, and the two ends of the limiting plate 130 cooperate with the support plate 120 to clamp the lens 300. Specifically, in order to improve the reliability of the lens 300 installation, a limiting plate 130 is also provided on the support plate 120. The middle part of the limiting plate 130 is arc-shaped and matches the convex surface of the lens 300. During installation, the middle part of the limiting plate 130 is attached to the convex surface of the lens 300, and the two ends of the limiting plate 130 can be attached to the support plate 120 and fixed by welding or other means. In this way, the limiting plate 130 and the support plate 120 cooperate to clamp the lens 300, which can improve the reliability of the lens 300 installation and prevent the lens 300 from shifting due to vibration or temperature changes during use.

[0035] In one embodiment of this utility model, an installation channel is formed between the limiting plate 130 and the base plate 110, and the light strip 200 is disposed within the installation channel. During installation, the light strip 200 is inserted into the installation channel, and is limited and fixed by the side wall of the installation channel, preventing the light strip 200 from shifting due to vibration or temperature changes during use. This provides a stable installation space for the light strip 200. In addition, the open structure of the installation channel allows external airflow to enter. The airflow flows within the installation channel, carrying away the heat generated by the light strip 200, achieving effective heat dissipation. This can prevent the light strip 200 from experiencing performance degradation or damage due to excessive temperature, ensuring operational stability.

[0036] like Figure 3 and Figure 4 In one embodiment of this utility model, a limiting groove 111 is provided on the base plate 110. The limiting groove 111 extends along the length direction of the light strip 200 to both ends of the base plate 110. An avoidance groove 122 is provided on the side of the support plate 120 facing the light strip 200. The avoidance groove 122 is opposite to the limiting groove 111 and extends along the length direction of the light strip 200 to both ends of the support plate 120. The avoidance groove 122 and the limiting groove 111 together form an installation channel. During installation, the light strip 200 is inserted into the installation channel along the extension direction of the limiting groove 111 and the avoidance groove 122. The side walls of the limiting groove 111 and the avoidance groove 122 limit and fix the light strip 200. Since the limiting groove 111 and the avoidance groove 122 are located on the base plate 110 and the support plate 120 respectively, this structure can realize the quick installation and disassembly of the light strip 200, and facilitate the maintenance and replacement of the light strip 200.

[0037] In one embodiment of this utility model, the limiting plate 130 and the support plate 120 are detachably connected. Specifically, both ends of the limiting plate 130 can be fastened to the support plate 120 with screws. During installation, the lens 300 is placed on the window 121 of the support plate 120, and then the limiting plate 130 is placed over the arc surface of the lens 300. The lens 300 is positioned and fixed by screws passing through the screw holes at both ends of the limiting plate 130 and connecting to the screw holes on the support plate 120. During disassembly, the limiting plate 130 and the lens 300 can be removed together simply by unscrewing the screws. The above solution facilitates the cleaning, maintenance, or replacement of the lens 300. When the surface of the lens 300 is covered with dust or damaged, it is not necessary to disassemble the entire bracket 100; the limiting plate 130 can be removed directly to handle the lens 300, improving maintenance efficiency. In addition, if it is necessary to replace the lens 300 with a different specification or type, the detachable connection makes it easier to replace the lens 300.

[0038] In one embodiment of this utility model, at least two limiting plates 130 are provided, and the at least two limiting plates 130 are correspondingly arranged at both ends of the lens 300 along its length. In this solution, the two limiting plates 130 respectively fix both ends of the lens 300, which can effectively limit the lens 300, further enhancing the installation stability of the lens 300 and improving the reliability of the entire UV curing light source.

[0039] In one embodiment of this utility model, the support plate 120 is detachably connected to the base plate 110; and / or, the light strip 200 is detachably connected to the base plate 110. In this design, the base plate 110 has bolt holes, and the support plate 120 also has corresponding bolt holes. During installation, the support plate 120 is placed on the base plate 110, and then bolts are passed through the bolt holes to fix the two together. During disassembly, simply unscrewing the bolts allows the support plate 120 to be removed from the base plate 110, facilitating maintenance or replacement of the support plate 120. When the support plate 120 is damaged, it is not necessary to replace the entire bracket 100; only the support plate 120 needs to be replaced, reducing maintenance costs. Alternatively, the light strip 200 can also be fixed to the base plate 110 with screws, which facilitates the assembly and disassembly of the light strip 200.

[0040] like Figure 4In one embodiment of this utility model, a plurality of heat dissipation fins 112 are provided on the side of the base plate 110 opposite to the light strip 200. The plurality of heat dissipation fins 112 are arranged in parallel and spaced apart. In this solution, the heat dissipation fins 112 can increase the heat dissipation area of ​​the base plate 110. During the curing process, the light strip 200 generates heat when it is working, and the base plate 110 is in contact with the light strip 200, which can conduct heat. The heat dissipation fins 112, with their large surface area, can more effectively dissipate the heat on the base plate 110 to the surrounding environment, reduce the temperature of the base plate 110 and the light strip 200, thereby improving the stability and service life of the entire system. In addition, in this solution, the parallel arrangement of the heat dissipation fins 112 can ensure that the airflow between the heat dissipation fins 112 is relatively smooth, avoiding the reduction of heat dissipation effect due to airflow turbulence. In addition, maintaining a certain interval between the heat dissipation fins 112 can prevent mutual interference between the heat dissipation fins 112, ensuring that each heat dissipation fin 112 can fully contact the air, improving heat dissipation efficiency.

[0041] This utility model also proposes a curing box with a UV curing light source for curing the printed product. The specific structure of the UV curing light source is as described in the above embodiments. Since this curing box adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
