Description

Technical Field

[0001] This application relates to the field of dispensing, and more particularly to an irradiation device for UV dispensing. Background Technology

[0002] UV dispensing irradiation devices are widely used in electronics manufacturing, optical component packaging, and other fields. Their core function is to rapidly cure adhesives using an ultraviolet (UV) light source. Traditional UV dispensing irradiation devices typically consist of a UV lamp assembly, a housing, and a simple heat dissipation structure. However, with the continuous increase in device power, the UV lamp assembly generates a significant amount of heat during operation. If heat dissipation is not timely, the device temperature will rise, affecting the stability and lifespan of the light source. Furthermore, the heat dissipation design of traditional devices is relatively simple, usually relying on natural cooling or small fans for auxiliary cooling, resulting in low heat dissipation efficiency and making it difficult to meet the heat dissipation requirements of high-power UV dispensing irradiation devices.

[0003] To improve the heat dissipation efficiency of UV dispensing equipment, several improvement schemes have been proposed in the prior art. For example, a common approach is to install heat sinks or fins inside the housing to increase the heat dissipation area and thus enhance heat dissipation. Another approach is to install a fan inside the equipment to force airflow and accelerate heat removal. Furthermore, some technical solutions propose incorporating airflow channels within the housing to utilize air convection principles to remove heat from the equipment. While these solutions improve heat dissipation to some extent, they still have limitations. For instance, the design of heat sinks and fans increases the complexity and cost of the equipment, while the design of airflow channels often fails to fully utilize the internal space, resulting in limited improvements in heat dissipation efficiency.

[0004] Despite improvements in heat dissipation in existing technologies, the following drawbacks remain: Insufficient heat dissipation efficiency: While existing heat sink or fan designs can improve heat dissipation, they still struggle to quickly dissipate heat under high-power operating conditions, leading to excessively high internal temperatures and affecting the stability and lifespan of the ultraviolet light source. Complex structure and high cost: The fan or heat sink designs used in existing solutions increase the complexity and manufacturing cost of the equipment, and fan operation may also introduce noise and vibration issues. Low space utilization: The airflow channel designs in existing technologies fail to fully utilize the internal space of the equipment, resulting in an inefficient heat dissipation path and low heat removal efficiency.

[0035] Please refer to Figure 1 - Figure 5 One embodiment of this application provides a UV dispensing device 100, comprising:

[0036] Irradiation lamp assembly, used to provide ultraviolet light source;

[0037] A housing, including a support structure located inside it, the support structure comprising:

[0038] A support member is fixed inside the housing along the height direction of the housing;

[0039] A support component is fixedly connected to the support member and separates the inner cavity of the housing to form a receiving cavity and a heat dissipation cavity respectively. The illumination lamp group is fixed in the receiving cavity by the support component, and the heat dissipation cavity has a heat dissipation channel that penetrates the housing.

[0040] The illumination lamp assembly heats the air inside the heat dissipation cavity so that thermal convection occurs between the air inside the housing and the air outside the housing via the heat dissipation channel.

[0041] Furthermore, this solution provides a UV dispensing irradiation device, characterized by comprising an irradiation lamp assembly and a housing. The housing contains a support structure, which consists of a support member fixed along the height of the housing and a load-bearing component connected thereto. The load-bearing component divides the housing cavity into a receiving cavity and a heat dissipation cavity. The irradiation lamp assembly is fixed within the receiving cavity, and the heat dissipation cavity has a heat dissipation channel penetrating the housing. The irradiation lamp assembly heats the air within the heat dissipation cavity, and through the heat dissipation channel, thermal convection occurs with the external air, achieving efficient heat dissipation. The core of this design lies in the connection between the load-bearing component and the support member. The load-bearing component not only serves as the mounting base for the irradiation lamp assembly but also forms independent receiving and heat dissipation cavities by dividing the housing cavity. The receiving cavity is used to fix the irradiation lamp assembly, ensuring stable operation of the light source, while the heat dissipation cavity communicates with the external environment through the heat dissipation channel, forming a thermal convection path. This design fully utilizes the internal space of the housing, optimizes the heat dissipation path, and avoids the problem of heat accumulation in traditional heat dissipation designs. In addition, the fixed connection between the load-bearing component and the support member enhances the stability of the overall structure, reduces equipment deformation caused by vibration or temperature changes, thereby improving the reliability and service life of the equipment. This structural design significantly improves heat dissipation efficiency, allowing the equipment to maintain low-temperature operation even under high-power conditions, thus ensuring the stability and uniformity of the ultraviolet light source.

[0042] In one specific embodiment, the UV dispensing device further includes a light-diffusing plate, which is disposed on the carrier assembly to form a dispensing plane for supporting the workpiece. The carrier assembly has a light-illuminating surface that extends along the height direction of the housing, and the irradiation lamp group illuminates the light-diffusing plate through the light-illuminating surface.

[0043] Furthermore, a uniform light distribution plate is mounted on the support assembly to form a dispensing plane to support the workpiece. The support assembly has a light-emitting surface extending along the height of the housing, through which the illumination lamps project light onto the uniform light distribution plate. The function of the uniform light distribution plate is to evenly distribute the ultraviolet light source, ensuring consistent adhesive curing. The design of the light-emitting surface allows the ultraviolet light source to directly illuminate the uniform light distribution plate, reducing light energy loss. The connection between the support assembly and the uniform light distribution plate further optimizes the heat dissipation path. The installation position of the uniform light distribution plate is separated from the heat dissipation cavity, preventing heat accumulation near the plate, thus improving illumination uniformity while maintaining heat dissipation efficiency. In addition, the design of the light-emitting surface of the support assembly simplifies the optical path structure, reduces light scattering, and improves the utilization rate of the ultraviolet light source. The edge of the uniform light distribution plate is connected to the support assembly via fasteners, ensuring stable installation and preventing displacement due to vibration or temperature changes, thereby guaranteeing the flatness of the dispensing plane and the uniformity of illumination. This design not only improves the equipment's working efficiency but also reduces maintenance costs, making it suitable for high-precision dispensing scenarios.

[0044] In one specific embodiment, the illumination lamp assembly includes at least six closely arranged ultraviolet lamps, and the ultraviolet lamps extend along the width direction of the carrier component.

[0045] Furthermore, the specified illumination lamp assembly includes at least six closely arranged ultraviolet lamps, with the lamps extending along the width of the support component. This close arrangement of multiple ultraviolet lamps forms a high-intensity, wide-coverage ultraviolet light source, suitable for efficient curing of large workpieces. The lamps' width-extending design ensures a continuous and uniform light spot, avoiding curing blind spots. Simultaneously, the support structure along the width of the support component enhances the stability of the lamp installation, reducing light source displacement due to vibration. Lamp slots on the support component further fix the lamp positions, ensuring their close arrangement and consistent spacing, thereby improving the uniformity and stability of the light source. In addition, the arrangement of multiple lamps improves the equipment's applicability, meeting the curing needs of workpieces of different sizes. Through this design, the equipment maintains stable light source output even under high-power operating conditions, improving the efficiency and quality of dispensing curing.

[0046] In one specific embodiment, the UV dispensing device further includes a power supply component, which is disposed in the heat dissipation cavity and electrically connected to the irradiation lamp assembly.

[0047] Furthermore, a power supply component is added and integrated into the heat dissipation cavity, electrically connected to the illumination lamp assembly. The power supply component's placement makes full use of the heat dissipation cavity space, avoiding encroachment on the illumination area within the cavity, while simultaneously reducing the risk of circuit overheating through heat convection cooling within the cavity. The electrical connection design between the power supply component and the illumination lamp assembly shortens the wire length, reduces line impedance and energy loss, and improves electrical efficiency. In addition, the integrated design of the power supply component optimizes the equipment layout, reduces the structural complexity of introducing external power, and improves the overall integrity and portability of the equipment. The coordination between the power supply component's location and the heat dissipation channel further optimizes the heat dissipation path, preventing heat accumulation near the power supply component, thereby ensuring circuit stability and safety. This design not only improves the electrical performance of the equipment but also reduces manufacturing costs and maintenance difficulty.

[0048] In one specific embodiment, the supporting component has a heat dissipation hole group that extends through the height of the housing, and when viewed from a plane perpendicular to the dispensing plane, the heat dissipation hole group is located on the side of the housing away from the heat dissipation channel;

[0049] The illumination lamp assembly heats the air inside the heat dissipation cavity so that thermal convection occurs between the air and the air outside the housing through the heat dissipation hole assembly.

[0050] Furthermore, a series of heat dissipation holes are formed along the height of the housing on the supporting component, located on the side of the housing away from the heat dissipation channel. These holes and the heat dissipation channel form a multi-directional heat dissipation path, enhancing heat convection efficiency and preventing the formation of localized high-temperature areas. The placement of the heat dissipation holes allows heat to escape from different directions, further improving heat dissipation. The connection between the supporting component and the heat dissipation holes also optimizes the airflow distribution within the heat dissipation cavity, ensuring uniform heat dissipation and preventing uneven heat dissipation caused by turbulent airflow. In addition, the design of the heat dissipation holes coordinates with the layout of the light distribution plate to ensure that heat dissipation does not affect the uniformity of illumination, thereby improving the overall performance of the equipment. This multi-directional heat dissipation design not only improves heat dissipation efficiency but also simplifies the heat dissipation structure and reduces manufacturing costs.

[0051] In one specific embodiment, the heat dissipation hole group includes at least three heat dissipation holes, and when viewed perpendicular to the dispensing plane, the plurality of heat dissipation holes are arranged in a straight line along the length direction of the housing.

[0052] Furthermore, the defined heat dissipation hole group includes at least three heat dissipation holes extending in a straight line along the length of the housing. The straight-line arrangement of the heat dissipation holes simplifies the manufacturing process, reduces manufacturing costs, and the evenly distributed holes ensure uniform heat dissipation from the heat dissipation cavity, avoiding airflow turbulence. The straight-line extension design also forms a parallel heat dissipation path with the heat dissipation channel, further improving thermal convection efficiency. The number and arrangement of the heat dissipation holes are optimized to maximize heat dissipation while avoiding a decrease in structural strength due to excessive holes. This design is suitable for elongated housing structures, adapts to diverse industrial needs, and enhances the versatility and practicality of the equipment.

[0053] In one specific embodiment, the support structure further includes fasteners, and a plurality of the fasteners secure each edge of the light-diffusing plate to the load-bearing component.

[0054] Furthermore, fasteners are added to the support structure to secure the edges of the light-diffusing plate to the load-bearing components. The distribution of these fasteners ensures uniform stress on the light-diffusing plate, preventing displacement due to thermal expansion or mechanical vibration. The connection between the fasteners and the load-bearing components enhances structural rigidity, while the fasteners, made of high-temperature resistant materials, prevent deformation due to long-term heat exposure, ensuring the positional accuracy and irradiation stability of the light-diffusing plate. The fastener design also simplifies the installation and disassembly process of the light-diffusing plate, facilitating equipment maintenance and replacement. Through this design, the reliability and service life of the equipment are significantly improved.

[0055] In one specific embodiment, the carrier component includes:

[0056] The lamp holder has a lamp slot assembly, which is used to support the illumination lamp assembly.

[0057] The support plate has one end abutting against the bottom of the illumination lamp assembly and the other end facing the heat dissipation cavity. The support plate also separates the inner cavity of the housing to form the receiving cavity and the heat dissipation cavity located at the upper and lower ends of the housing, respectively.

[0058] Furthermore, the lamp holder has slots for securing the lamp assembly, and one end of the support plate abuts against the bottom of the lamp assembly, while the other end extends into the heat dissipation cavity, separating the inner cavity of the housing to form upper and lower chambers. This combination of the lamp holder and support plate achieves both precise lamp positioning and efficient heat dissipation. The support plate acts as a heat-conducting medium, rapidly transferring heat from the lamp assembly to the heat dissipation cavity. The aluminum support plate further accelerates heat conduction, while the partition design prevents heat from flowing back into the housing cavity, ensuring an independent and efficient heat dissipation path. This design not only improves heat dissipation efficiency but also enhances the structural stability and reliability of the equipment.

[0059] In one specific embodiment, the tray is made of aluminum.

[0060] Furthermore, aluminum's lightweight properties reduce the overall weight of the equipment, its high thermal conductivity accelerates heat transfer from the illumination lamp assembly to the heat dissipation cavity, and the oxide layer on the aluminum surface enhances corrosion resistance and extends the lifespan of the tray. The contact surface between the tray and the lamp holder is coated with an insulating layer to avoid the risk of short circuits caused by direct metal contact, while the high-temperature resistance of the insulation layer ensures long-term operational reliability. This design not only improves heat dissipation efficiency but also enhances the electrical safety and mechanical stability of the equipment.

[0061] In one specific embodiment, an insulating layer is coated on the contact surface between the tray and the lamp holder.

[0062] Furthermore, the insulation layer is made of high-temperature resistant ceramic or polymer coating. Its function is to block the current conduction path, preventing leakage or short circuits when the lamp tube contacts the metal support plate. The insulation layer also possesses a certain degree of flexibility, mitigating the impact of lamp tube vibration on the support plate and improving the electrical safety and mechanical stability of the equipment. Simultaneously, the insulation layer does not hinder heat conduction through the support plate to the heat dissipation cavity, ensuring both efficient heat dissipation and safety. This design not only improves the reliability of the equipment but also reduces maintenance costs.

[0063] Therefore, this application divides the inner cavity of the housing into a receiving cavity and a heat dissipation cavity by fixing the load-bearing components and the support members, and sets a heat dissipation channel that runs through the housing in the heat dissipation cavity to achieve efficient heat dissipation by utilizing the principle of thermal convection. This design not only simplifies the structure and reduces costs, but also makes full use of the internal space of the equipment, significantly improving heat dissipation efficiency and solving the problems of insufficient heat dissipation, complex structure and low space utilization in the prior art.

[0064] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
