Description

Technical Field

[0001] This application relates to the field of curing lamp technology, and in particular to an ultraviolet curing lamp. Background Technology

[0002] An ultraviolet curing lamp (UV curing lamp) is a device that uses ultraviolet light to initiate a chemical reaction, thereby achieving rapid curing of materials. Its working principle is based on photochemical reaction. A UV light source (such as UV, LED lamp or traditional mercury lamp) emits ultraviolet photons of a specific wavelength. The photoinitiator (or photosensitizer) in the UV coating or adhesive absorbs the UV photons and is excited to an excited state. The excited state photoinitiator releases active free radicals or ions. The active free radicals or ions react with the double bonds of monomers (such as acrylate, epoxy resin, etc.) in the coating to form a solid network structure, which makes the coating or adhesive quickly change from a liquid state to a solid state.

[0003] In existing technologies, ultraviolet curing lamps typically have hundreds or even thousands of light-emitting units, which are usually fixed as a single unit and work together.

[0004] Regarding the aforementioned technologies, the inventors believe that since the light-emitting unit of the ultraviolet curing lamp is fixed as a whole, when individual light-emitting units are damaged, the entire machine needs to be disassembled and repaired, which makes maintenance inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a UV curing lamp to improve the problem that when the light-emitting unit of a UV curing lamp is fixed in one piece, the entire machine needs to be disassembled and repaired when individual light-emitting units are damaged, which leads to inconvenience in maintenance.

[0006] This application provides a technical solution for an ultraviolet curing lamp, which adopts the following approach:

[0007] An ultraviolet curing lamp includes a housing, a mounting plate on one side of the housing, a plurality of mounting slots on the mounting plate, a fixing frame in the mounting slots, the fixing frame including a frame body, a pair of fixing plates on opposite sides of the frame body, and a pair of pressure plates abutting against the fixing plates, a light-emitting module abutting against the pressure plates in the fixing frame, and a plurality of fixing screws penetrating the pressure plates and fixing plates and fixed to the mounting plate in the fixing frame.

[0008] By adopting the above technical solution, several mounting slots are provided to facilitate the fixed installation of the mounting frame, and the mounting frame facilitates the fixed installation of the light-emitting modules. Furthermore, by fixing the mounting plate with the light-emitting modules to the outer casing, the light-emitting modules can conduct electricity through the internal circuitry of the casing, thereby emitting light. The use of multiple light-emitting modules covering the mounting plate improves the utilization rate of the mounting plate area, increases the ultraviolet light coverage area, and increases the irradiation area of ​​the ultraviolet curing lamp. The mounting frame and modular light-emitting templates eliminate the need for complete machine disassembly, facilitating the removal and replacement of individual light-emitting modules for maintenance and improving maintenance efficiency.

[0009] Optionally, a sealing ring is provided on the inner sidewall of the mounting groove corresponding to the fixing frame.

[0010] By adopting the above technical solution, the sealing ring is used to tightly fix the fixing frame, reducing the possibility of the light-emitting module shaking, improving the installation stability of the light-emitting module, and ensuring stable illumination by the light-emitting module light source; at the same time, the sealing ring is used to seal the outer shell, which helps to reduce the entry of dust and other impurities into the outer shell and affect the operation of its internal components, thereby improving the service life of the curing lamp.

[0011] Optionally, a light-transmitting protective plate covering the light-emitting module is provided on one side of the fixed frame.

[0012] By adopting the above technical solution, the main function of the light-transmitting protective plate is to protect the lamp tube and light source of the ultraviolet curing lamp from the influence of the external environment, such as dust, dirt, splashed liquids, etc. These contaminants may affect the heat dissipation performance of the lamp tube, or even cause damage to the lamp tube or shorten its service life. By setting the light-transmitting protective plate to filter out ultraviolet rays of specific wavelengths, especially those short-wave ultraviolet rays that are harmful to the human body, the health of the operator is protected, and it can also prevent ultraviolet rays from causing unnecessary damage to the surrounding environment and materials. The light-transmitting protective plate can also improve curing efficiency by optimizing the propagation path and intensity of light.

[0013] Optionally, the light-transmitting protective plate is disposed between the pressing plates, and the pressing plate is provided with a locking groove corresponding to the light-transmitting protective plate.

[0014] By adopting the above technical solution, the fixing screws of the pressure plate and the locking groove of the light-transmitting protective plate facilitate the quick and easy installation and removal of the light-transmitting protective plate. This is especially important in scenarios where lamp tubes need to be replaced frequently or the protective plate needs to be cleaned. It can reduce maintenance time and workload: due to the ease of installation and removal, maintenance personnel can quickly replace or clean the protective plate, maintain the equipment in good working condition, reduce maintenance time, reduce equipment downtime, and improve production efficiency.

[0015] Optionally, a resilient fastener is provided in the engagement groove.

[0016] By adopting the above technical solution, the elastic fastener has excellent elasticity, which can effectively absorb the vibration generated during equipment operation and prevent these vibrations from being transmitted to the light-transmitting protective plate, thereby reducing the risk of loosening or damage to the protective plate. By reducing the impact of vibration on the light-transmitting protective plate, the rubber pad can extend the service life of the protective plate and reduce the frequency of maintenance and replacement. The elastic fastener can fill the tiny gap between the locking groove and the light-transmitting protective plate, providing better sealing performance and preventing dust, moisture and other substances from entering the interior of the UV curing lamp, thus better protecting the light-emitting module and internal electronic components.

[0017] Optionally, the light-emitting module is provided with a wire, which passes through the fixing frame, and a terminal is provided at the end of the wire away from the light-emitting module.

[0018] By adopting the above technical solution, the installation of terminal blocks allows operators to quickly and easily connect wires without the need for additional tools such as screwdrivers or pliers, thus shortening installation time and improving installation efficiency. The simplified wiring process reduces the possibility of wiring errors, lowering the risk of equipment failure due to such errors. The terminal blocks also allow for quick disconnection and reconnection of wires, facilitating operation during equipment maintenance or repair. This reduces maintenance time and consequently minimizes equipment downtime during maintenance or repair, thereby improving production efficiency.

[0019] Optionally, the fixing frame is provided with heat dissipation fins.

[0020] By adopting the above technical solution, the heat dissipation fins can more effectively dissipate the heat generated by the light-emitting module, thereby reducing the temperature of the light-emitting module, facilitating the protection of the light-emitting module, extending its service life, and also benefiting the long-term use of the light-emitting module.

[0021] Optionally, a frame plate is provided inside the housing corresponding to the mounting plate, and the mounting plate is fixedly connected to the frame plate.

[0022] By adopting the above technical solution, the mounting plate is fixed by setting a frame plate, and the mounting plate is installed by aligning the frame plate with the edge line of the mounting plate, which improves the installation efficiency of the mounting plate and facilitates the accurate installation position of the mounting plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects of ultraviolet curing lamps:

[0024] 1. By setting several mounting slots, it is easy to fix the mounting frame, and by setting the mounting frame, it is easy to fix the light-emitting module. Then, by fixing the mounting plate with the light-emitting module to the outer shell, the light-emitting module can be connected to the internal circuit of the outer shell to conduct electricity, thereby emitting light. By setting multiple light-emitting modules to cover the mounting plate, it is beneficial to improve the utilization rate of the mounting plate area, increase the ultraviolet light coverage area, and increase the irradiation area of ​​the ultraviolet curing lamp. By setting the mounting frame and modular light-emitting template, it is not necessary to disassemble the whole machine, and it is easy to remove individual light-emitting modules for maintenance and replacement, thus improving maintenance efficiency.

[0025] 2. The main function of the light-transmitting protective plate is to protect the UV curing lamp tubes and light source from external environmental influences, such as dust, dirt, and splashed liquids. These contaminants may affect the heat dissipation performance of the lamp tubes, or even cause damage to the lamp tubes or shorten their lifespan. By setting up the light-transmitting protective plate, specific wavelengths of ultraviolet light are filtered out, especially those short-wave ultraviolet rays that are harmful to the human body, protecting the health of the operator and preventing unnecessary damage to the surrounding environment and materials caused by ultraviolet rays. The light-transmitting protective plate can also improve curing efficiency by optimizing the light propagation path and intensity.

[0026] 3. By providing terminal blocks, operators can quickly and easily connect wires without the need for additional tools such as screwdrivers or pliers, shortening installation time and improving installation efficiency. The simplified wiring process reduces the possibility of wiring errors, lowering the risk of equipment malfunction due to incorrect wiring. Terminal blocks also allow for quick disconnection and reconnection of wires, facilitating operation during equipment maintenance or repair. This reduces maintenance time and consequently minimizes equipment downtime during maintenance or repair, improving production efficiency. Attached Figure Description
