Description

Technical Field

[0001] The present invention relates to the technical field of light curing, and in particular to a wheel hub ultraviolet light curing device. Background Art

[0002] UV curing technology (UV) involves a photoprocessing process that uses ultraviolet light of a specific wavelength to polymerize a liquid reaction system into a solid state. The UV curing reaction is essentially a photoinitiated polymerization and cross-linking reaction of the liquid formulation in the reaction system. UV-curable coatings are the earliest example of the successful large-scale industrial application of UV curing technology and are currently the largest-produced and sold product in the UV curing industry.

[0003] In existing wheel hub painting processes, most paints are still traditional materials, which are cured by heating. Light-curing paints have now emerged and can be applied to wheel hubs, but the surface contours of wheels are highly undulating, requiring light-curing equipment more suitable for wheel hubs. Summary of the Invention

[0004] To address the aforementioned issues, the present invention discloses a wheel hub UV curing device comprising a main frame, a passageway for workpieces to pass through, and a lifting frame disposed directly above the passageway. The lifting frame is provided with a plurality of secondary light sources, which illuminate the passageway. Two primary screws are threadedly engaged with the lifting frame, and the primary screws are rotatably engaged with the main frame. This allows the secondary light sources to illuminate the workpiece from directly above, driving the primary screws to rotate. As the lifting frame is raised or lowered, the secondary light sources follow suit, controlling the distance between the secondary light sources and the workpiece.

[0005] Furthermore, the lifting frame is a rectangular frame, and four horizontal bars for installing second light sources are provided on the rectangular frame. One of the two middle horizontal bars is installed with three second light sources, the other is installed with two second light sources, and the other two horizontal bars are installed with redundant second light sources, and whether to enable them is determined according to the production situation.

[0006] Two primary light sources are mounted on one side of the main frame, with the primary light sources illuminating the passageway. A secondary screw is threaded into the lower portion of the primary light sources. The primary light sources illuminate the sides of the workpiece, while the secondary screw is rotated to control the distance between the primary light sources and the workpiece.

[0007] Preferably, a second motor is fixedly connected to the main frame, the output end of the second motor being fixedly connected to one of the first screws, the ends of both first screws being fixedly connected to sprockets, and a second chain being sleeved on the sprockets. When the second motor is activated, the second chain acts to raise or lower the lifting frame. The provision of two first screws simultaneously enhances the smoothness of the lifting frame.

[0008] Preferably, guide rods are inserted and slidably provided at the four corners of the lifting frame, and the ends of the guide rods are fixedly connected to the main frame. The provision of the guide rods also improves the stability of the lifting frame during operation.

[0009] Preferably, a sliding platform is horizontally fixedly connected to the main frame, and the lower portion of the first light source is slidably engaged on the sliding platform. A first motor is fixedly connected to the lower portion of the main frame, and the ends of the first motor and the second screw are fixedly connected to sprockets, and a first chain is sleeved on the sprockets. That is, the first light source slides on the sliding platform, and under the operation of the first motor and the transmission of the first chain, the first light source is moved away from or closer to the workpiece.

[0010] Preferably, the first light source and the second light source are both UV electrodeless lamps. Compared with traditional mercury lamps, UV electrodeless lamps have the advantages of long life, high efficiency, short startup time, and no generation of harmful gases, which is more environmentally friendly.

[0011] Preferably, an air duct is provided on the side of the main frame, and each of the first light source and the second light source is provided with a fan for heat dissipation, thereby achieving heat dissipation of the first light source and the second light source.

[0012] The beneficial effects of the present invention are as follows:

[0013] A first light source and a second light source are provided, which can realize irradiation of the wheel hub from two directions, and the distances between the first light source, the second light source and the wheel hub can be adjusted to meet the needs of light curing production of the wheel hub.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0020] like Figures 1 to 3 As shown, a wheel hub UV curing device includes a main frame 1. The main frame 1 is a rectangular structure and is provided with height-adjustable support feet at the bottom to facilitate equipment installation. A channel for the workpiece is provided in the main frame 1. The workpiece passes through the channel through a conveying device. Here, the workpiece is a wheel hub 14, and a lifting frame 7 is provided directly above the channel. Furthermore, the lifting frame 7 is a rectangular frame. Several second light sources 9 are provided on the lifting frame 7. Similarly, the second light sources 9 are located directly above the channel, and the second light sources 9 are irradiated toward the channel. Two first screws 6 are threadedly provided on the lifting frame 7, and the first screw 6 is rotatably engaged with the main frame 1, that is, the first screw 6 is driven to rotate, thereby realizing the rise or fall of the lifting frame 7 and controlling the distance between the second light source 9 and the wheel hub 14.

[0021] Furthermore, four cross bars with second light sources 9 installed are fixedly connected to the middle of the rectangular frame. One of the two middle cross bars is installed with three second light sources 9, and the other is installed with two second light sources 9. The second light sources 9 on the cross bars on both sides are redundant settings, which can be enabled to improve production efficiency or when the second light sources 9 on the two middle cross bars are damaged.

[0022] Two first light sources 4 are set on one side of the main frame 1. The first light sources 4 are located in the middle of the main frame 1, and the first light sources 4 are directed toward the channel, that is, the first light sources 4 are used to illuminate the side of the hub 14. The lower thread of the first light source 4 is equipped with a second screw 11, which drives the second screw 11 to rotate to adjust the distance between the first light source 4 and the hub 14.

[0023] A second motor 10 is fixedly connected to the main frame 1, and the output end of the second motor 10 is fixedly connected to one of the first screws 6. The second motor 10 is started to drive the first screw 6 to rotate. If necessary, a bevel gear set can be used to connect the second motor 10 and the first screw 6 to change the direction of transmission to avoid interference with the lifting of the lifting frame 7 caused by the arrangement of the second motor 10. The ends of the two first screws 6 are fixedly connected to sprockets, and a second chain 8 is sleeved on the sprockets. The rotation of the other first screw 6 is realized by the second chain 8, thereby improving the stability of the lifting of the lifting frame 7.

[0024] The four corners of the lifting frame 7 are all interspersed and slidably provided with guide rods 5, and the ends of the guide rods 5 are fixedly connected to the main frame 1. The setting of the guide rods 5 also improves the stability of the lifting frame 7.

[0025] A sliding platform 12 is fixedly connected horizontally to the main frame 1, and the lower portion of the first light source 4 slides and fits on the sliding platform 12. Furthermore, a slider is fixedly connected to the lower end of the first light source 4, and the slider slides and fits on the sliding platform 12. The second screw 11 is threadedly engaged with the slider. The lower portion of the main frame 1 is fixedly connected to the first motor 3. The ends of the first motor 3 and the second screw 11 are both fixedly connected to sprockets, and the first chain 2 is sleeved on the sprocket. When the first motor 3 is started, the first light source 4 is moved toward or away from the hub 14 through the transmission of the first chain 2 and the second screw 11.

[0026] Both the first light source 4 and the second light source 9 are UV electrodeless lamps. Compared to traditional mercury lamps, the use of UV electrodeless lamps is different in that the service life of electrodeless lamps can reach 5,000 to 10,000 hours, while traditional mercury lamps have a service life of 500 to 1,000 hours; the energy conversion rate of electrodeless lamps is more than 10 times that of traditional mercury lamps; the startup time of electrodeless lamps is about 1 minute, while traditional mercury lamps take more than 10 minutes; and electrodeless lamps are more environmentally friendly than traditional mercury lamps and do not produce harmful gases.

[0027] The side of the main frame 1 is provided with an air duct 15, and each first light source 4 and second light source 9 is provided with a fan for heat dissipation, that is, heat is dissipated for each UV electrodeless lamp to ensure stable operation of the equipment.

[0028] Further, such as Figure 3 As shown, during equipment production, a separate area is planned, and a chiller 16 is installed within this area. The evaporation section of chiller 16 is located at the air inlet of air duct 15. The fan rotates, forcing air through the evaporation section, pre-cooling the air and thus improving the heat dissipation effect of the electrodeless lamps. An operating console 13 is located outside the area to enable equipment startup and shutdown, status monitoring, and parameter setting. For example, the current status of each electrodeless lamp, its startup status, light intensity, temperature, and wind pressure are normal.

[0029] When the equipment is started, the hub 14 passes through the main frame 1 under the conveying of the conveyor, and the electrodeless lamp works to illuminate the hub 14 to solidify the paint on its surface. In addition, during the operation of the equipment, personnel are not allowed to enter the area.

[0030] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above-mentioned embodiment, but also include technical solutions composed of any combination of the above technical features.
