[0002] Ultraviolet curing light sources are special light source devices that use the energy of ultraviolet light to cause materials containing photosensitizers (also known as photoinitiators) to undergo rapid chemical reactions, thereby achieving curing. This type of light source is widely used in many industrial fields, especially in scenarios where materials need to be cured quickly.

[0003] In existing technologies, the UV curing light source is directly placed on the UV curing equipment. At the same time, the entire equipment needs to be placed on a flat and stable surface. After installation, the items to be cured need to be placed within the irradiation range of the UV curing light source, and the surface of the items needs to be clean and flat. At this time, the UV curing light source will be activated to start curing the items.

[0004] However, such UV curing light sources are usually in a state of direct exposure during operation. For UV curing equipment without external protective devices, the UV radiation emitted can easily irradiate the human body, thereby causing harm to the human body. Utility Model Content

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0024] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0025] Example Reference Figures 1-4 As shown, this utility model provides an ultraviolet curing light source, including a protective box 1, a light source assembly 6, and a box door 3. The protective box 1 is hollow inside, and a feeding inlet 2 is opened on its side wall. The feeding inlet 2 is connected to the inside of the protective box 1, and the operator can feed the product to be cured into the protective box 1 through the feeding inlet 2. The light source assembly 6 is set and installed inside the protective box 1. Specifically, the light source assembly 6 is set on the inner top wall of the protective box 1. When the product to be cured is fed into the protective box 1, the light source assembly 6 is located above the product to be cured and is used to irradiate and cure the product.

[0026] The cabinet door 3 is located at the inlet 2. The size of the cabinet door 3 is adapted to the size of the inlet 2. The cabinet door 3 is rotatably connected to the protective cabinet 1 via a hinge 4. The cabinet door 3 has open and closed states. When the cabinet door 3 is in the closed state, the cabinet door 3 blocks the inlet 2. When the cabinet door 3 is in the open state, the inlet 2 is exposed, allowing the staff to put the product to be cured into the protective cabinet 1 through the inlet 2. At the same time, a flat lock 5 is also provided on the cabinet door 3 to lock the cabinet door 3. The flat lock 5 can be an existing door lock and will not be described again.

[0027] By setting up a closed protective enclosure 1 and an openable and closable enclosure door 3, a physically isolated curing space is constructed, which eliminates the harm of ultraviolet radiation to operators from the source and achieves inherent safety. There is no need to set up additional protective devices on the light curing equipment. The protective enclosure 1 can be directly fixed to the light curing equipment machine.

[0028] When the cabinet door 3 is closed, it completely blocks the inlet 2, forming a sealed environment that completely confines the high-intensity ultraviolet radiation inside the protective cabinet 1. When curing is required, simply open the cabinet door 3, place the product in, and close it to safely start the light source assembly 6. This structure allows the ultraviolet curing light source to function as a complete safe working unit without relying on external protective devices, thus preventing ultraviolet radiation from irradiating the human body.

[0029] As one specific implementation method, refer to Figure 1 As shown, the light source assembly 6 includes a circuit board 61 and ultraviolet lamps (not shown in the figure). The circuit board 61 is arranged in parallel and is mounted on the inner top wall of the protective housing 1. Multiple ultraviolet lamps are arranged evenly on the bottom wall of the circuit board 61. The multiple ultraviolet lamps are electrically connected to the circuit board 61. The array of ultraviolet lamps is arranged above the product to be cured, thereby ensuring that the product surface receives uniform ultraviolet irradiation and avoiding localized poor curing. The circuit board 61 provides stable electrical connection and support for all ultraviolet lamps, which facilitates the modular production, installation and maintenance of the light source assembly 6, simplifies the assembly process, and facilitates the future testing and replacement of individual ultraviolet lamps.

[0030] Furthermore, the light source assembly 6 also includes a protective component 62. In this embodiment, the protective component 62 is a transparent protective glass. The protective component 62 is fixedly installed on the inner wall of the protective housing 1 and located below the ultraviolet lamp body. The protective component 62 covers the entire bottom surface of the circuit board 61, and a gap is left between the protective component 62 and the ultraviolet lamp body. By setting the protective component 62, secondary physical protection is provided for the ultraviolet lamp body. Even if the operator accidentally touches it while the housing door 3 is open, it can avoid direct contact with the high-voltage circuit or the high-temperature ultraviolet lamp body, thus improving the safety of the equipment. At the same time, it can also prevent tools or products from accidentally bumping and damaging the delicate ultraviolet lamp body and circuit during the handling process.

[0031] As another implementation method, refer to Figure 1 As shown, it also includes a heat dissipation component 7, which is disposed on the outer wall of the protective housing 1 and is used to dissipate heat from the light source component 6. Specifically, the heat dissipation component 7 is disposed on the top wall of the protective housing 1, so that the heat dissipation component 7 corresponds to the light source component 6 and is close to the light source component 6, so that the heat dissipation component 7 can dissipate heat from the light source component 6 more efficiently.

[0032] By setting up the heat dissipation component 7, the working temperature of the light source component 6 can be effectively guaranteed. The ultraviolet lamp body generates a lot of heat when it is working. The sealed protective box 1 environment is more likely to accumulate high temperature. The external heat dissipation component 7 can actively conduct the internal heat to the outside of the protective box 1 and dissipate it, preventing the light source from decaying faster, the circuit from aging or even being damaged due to overheating. This ensures the stability of the curing effect and the durability of the equipment, guarantees the stability of the light output of the ultraviolet curing light source and extends its service life.

[0033] Specifically, the heat dissipation assembly 7 includes a heat dissipation base 71, heat dissipation fins 72, and a cooling fan 73. The heat dissipation base 71 is horizontally positioned and parallel to the circuit board 61. The heat dissipation fins 72 are located on the side of the heat dissipation base 71 facing away from the circuit board 61 and are vertically positioned to the heat dissipation base 71. Multiple heat dissipation fins 72 are evenly distributed on the heat dissipation base 71. The cooling fan 73 is mounted on the heat dissipation base 71 and located on the side of the heat dissipation fins facing away from the heat dissipation base 71. There is a gap between the heat sink 71 and the heat dissipation fins 72. When the cooling fan 73 is turned on, the cooling fan 73 can dissipate the heat from the heat dissipation fins 72. During use, the heat sink base 71 is in close contact with the heat source area of ​​the protective box 1, i.e., the circuit board 61, which is responsible for quickly conducting away the heat. The heat dissipation fins 72 greatly increase the contact area with the air, enhancing the passive heat dissipation capability. The cooling fan 73 actively blows the heat dissipation fins 72, forcing convection and greatly improving the heat dissipation efficiency. The combination of the three ensures that the light source component 6 can still be maintained within a suitable temperature range under high power operation.

[0034] Furthermore, the protective housing 1 is provided with heat dissipation holes 74, which are adapted to the shape of the heat dissipation base 71. The heat dissipation holes 74 are located on the top of the protective housing 1 and at the heat dissipation component 7. The circuit board 61 is located at and below the heat dissipation holes 74. The heat dissipation base 71 is placed inside the heat dissipation holes 74 and fits against the circuit board 61. The position of the heat dissipation holes 74 is precisely aligned with the center of the heat source. The heat dissipation base 71 directly contacts the core heat-generating component (circuit board 61) through this hole, achieving direct heat conduction with minimal thermal resistance and maximizing heat dissipation efficiency.

[0035] To connect the heat sink base 71 to the protective housing 1, the heat dissipation assembly 7 also includes a connector 75. The connector 75 is directly configured as a connecting plate. The connector 75 is located on the side of the heat sink base 71 facing away from the circuit board 61 and at the contact point between the outer wall of the protective housing 1 and the heat sink base 71. The connector 75 is detachably connected to both the protective housing 1 and the heat sink base 71, thereby restricting and fixing the heat sink base 71 to the protective housing 1. When it is necessary to clean the dust on the heat sink fins 72 or to inspect the heat sink base 71, it can be easily removed from the housing without disassembling the entire housing or the light source module, thus simplifying maintenance operations.

[0036] As a further embodiment, the heat dissipation assembly 7 also includes a fan mount 76. Multiple cooling fans 73 are provided, and the fan mount 76 has multiple fan holes 77 corresponding to the cooling fans 73. In this embodiment, four cooling fans 73 are provided, and four fan holes 77 are also provided. The four cooling fans 73 are arranged one-to-one with the four fan holes 77, and the fan blades of the cooling fans 73 are aligned with the fan holes 77. The cooling fans 73 are detachably connected to the fan mount 76. The fan mount 76 is connected to the heat dissipation base 71, thereby mounting the cooling fans 73 above the heat dissipation fins 72. The fan mount 76 serves as an installation platform, ensuring that multiple cooling fans 73 are mounted above the heat dissipation fins 72 and are fixed in position relative to the heat dissipation fins 72, forming a uniform and concentrated forced airflow.

[0037] In order to fix the fan mount 76 to the heat sink base 71, a connecting part 78 is provided on the side of the fan mount 76 facing the protective housing 1, and an end plate 9 is detachably provided on the side of the heat sink base 71 facing the fan mount 76. The side wall of the connecting part 78 and the side wall of the end plate 9 are detachably connected. By setting the end plate 9 and the connecting part 78, the fan mount 76 and the heat sink base 71 are fixed, ensuring the stability of the connection.

[0038] As a specific implementation, the UV curing light source also includes a terminal block 10, which is fixed on the heat sink base 71. The terminal block 10 is provided with a copper connector 11 and is electrically connected to the circuit board 61. At the same time, an aviation connector 12 is also connected to the copper connector 11 to ensure the reliability and stability of current transmission.

[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
