Description

Technical Field

[0001] This utility model relates to the field of curing equipment technology, specifically to a device suitable for UV curing of coatings. Background Technology

[0002] Hexahedral equipment, such as speaker housings and jewelry box housings, typically requires coating after production to enhance their appearance. UV-cured coatings exhibit strong adhesion to various substrates (such as plastics, metals, and wood), ensuring the coating is resistant to peeling. They also offer a wide range of colors and effects, including high-gloss, matte, and metallic finishes. This not only provides high-quality coating protection but also extends the lifespan of the equipment. After UV-cured coating is applied to hexahedral equipment, a UV curing machine is usually used to accelerate the curing process, thereby improving the production efficiency of the equipment.

[0003] A UV curing machine is a mechanical device that emits strong, usable ultraviolet light. It has been widely used in industries such as printing, electronics, building materials, and machinery. The types and styles of UV curing machines vary depending on the products they are curing, but their ultimate purpose is the same: to cure fluids such as UV adhesives, UV paints, UV inks, and UV coatings.

[0023] like Figure 1-4 As shown: This embodiment provides an equipment suitable for UV curing of coatings, including a frame 100. The frame 100 is equipped with a lifting device for hoisting a coated hexahedral workpiece. A protective cover 200 is provided on the frame 100. A lifting mechanism 300 is located inside the protective cover 200 on the frame 100. The lifting mechanism 300 includes a drive assembly 310 mounted on the frame 100. A lifting frame 320 is mounted on the drive assembly 310. A UV curing lamp 400 is mounted on the lifting frame 320. The drive assembly 310 drives the lifting frame 320 to carry the UV curing lamp. The lamp 400 moves vertically up and down. This utility model can drive the lifting frame 320 with the UV curing lamp 400 to perform lifting operations through the drive component 310, thereby realizing fast and efficient curing operations for objects of various sizes. Moreover, the curing speed can be easily and quickly adjusted by adjusting the distance between the UV curing lamp 400 and the object to be cured. It also makes it easy for maintenance personnel of different heights to disassemble, repair or replace the UV curing lamp 400 without the need to use a stool to raise or bend over to operate, making the operation more convenient and efficient.

[0024] According to one embodiment of the present invention, such as Figure 1-4As shown, the drive assembly 310 includes fixing plates 311 respectively disposed on the upper part of the frame 100 and on the upper and lower sides of the front and rear inner sidewalls of the protective cover 200. A drive component 312 is disposed on the outer side of one of the fixing plates 311. The drive component 312 is a stepper motor. A reducer 700 is disposed at the output shaft end of the stepper motor. The output end of the reducer 700 is engaged with the first rotating shaft 313. This utility model can use the reducer 700 to adjust and reduce the rotation speed of the stepper motor before outputting it to the first bevel gear 314, thereby realizing the adjustment of the drive speed. The moving component 310 drives the lifting frame 320 to rise and fall at different speeds, making operation more convenient. The output shaft of the driving component 312 is equipped with a first rotating shaft 313. First bevel gears 314 are respectively installed at both ends of the first rotating shaft 313. Each first bevel gear 314 is meshed with a second bevel gear 315, which is connected to it for transmission. A second rotating shaft 316 is installed on the upper part of the rotating shaft of each second bevel gear 315. A screw 317 is installed on the upper part of the second rotating shaft 316. A threaded sleeve 318 is installed on the lifting frame 320 and located on the axis of the screw 317. 317 is threaded and passes through the threaded sleeve 318. Guide holes are respectively provided on the lifting frames 320 located on both sides of the threaded sleeve 318. A guide rod 319 is inserted into each guide hole. The two ends of the guide rod 319 are respectively fixed to the lower part of the fixing plate 311 located on the same side. This invention can drive the first rotating shaft 313 and its first bevel gear 314 to rotate together through the rotation of the output shaft of the driving component 312. The rotating first bevel gear 314 can drive the second bevel gear 315 meshing with it and its... The upper second rotating shaft 316 rotates together with the screw 317. In addition, the threaded connection between the threaded sleeve 318 and the screw 317, as well as the guiding and limiting function of the guide rod 319 on the lifting frame 320, allow the rotating screw 317 to drive the threaded sleeve 318 to move the lifting frame 320 up and down along the screw 317. This enables convenient and quick adjustment of the height of the lifting frame 320. A single driving component 312 can achieve stable and efficient lifting of the entire fixed frame, resulting in better coordination and more stable and reliable lifting operations.

[0025] According to another embodiment of the present invention, such as Figure 1As shown, inspection doors 201 are provided on the front and rear sides of the protective cover 200, and transparent observation windows 202 are provided on the inspection doors 201. This utility model allows for maintenance of the UV curing equipment inside the protective cover 200 through the inspection doors 201, and allows for real-time monitoring of the curing status inside the protective cover 200 through the transparent observation windows 202, making operation more convenient. There are five sets of UV curing lamps 400, and each set of UV curing lamps 400 is arranged in a V-shape. The opening of each set of UV curing lamps 400 faces the side wall of the hexahedral workpiece located on the same side. This utility model can achieve efficient and rapid curing of all surfaces of the hexahedral workpiece except the bottom surface through the V-shaped arrangement of curing lamps, resulting in better curing effect and higher efficiency.

[0028] How to use this utility model:

[0029] First, it needs to be clarified that the UV curing device involved in this utility model is mainly used for the rapid shaping and curing of various workpieces coated with coatings to be cured. This utility model takes the curing of a hexahedral speaker shell after UV coating as an example to describe its usage in detail. When it is necessary to fix the shell of the hexahedral workpiece, the operator first starts the drive unit 312 to rotate according to the height of the workpiece to be cured. The rotation of the output shaft of the drive unit 312 drives the first rotating shaft 313 and the first bevel gear 314 on it to rotate together. The rotating first bevel gear 314 can drive the second bevel gear 315 meshing with it and the second rotating shaft 316 on its upper part to rotate together with the screw 317. In addition, the threaded connection between the threaded sleeve 318 and the screw 317, and the guiding and limiting function of the guide rod 319 on the lifting frame 320, the rotating screw 317 can drive the threaded sleeve 318 to move the lifting frame 320 up and down along the screw 317, thereby realizing the adjustment of the lifting frame 320 and the UV curing lamp 400 on it to facilitate the curing of the workpiece. The UV curing equipment is preheated by turning on the UV lamps after the workpiece is positioned at the desired height for efficient curing. The operator then attaches the hook from the lifting device (fixed to the frame 100) to the threaded ring on the fixed surface of the workpiece. The UV curing equipment is then started. After curing, the workpiece is removed and replaced with the next batch. This invention uses a protective cover 200 on the frame 100 to block the light from the UV curing lamp 400 during the curing process, preventing radiation exposure to the operator. Furthermore, the lifting mechanism 300 allows for simultaneous and rapid adjustment of the height of the UV curing lamp 400 and the suction hood 500, ensuring the suction hood 500 always reaches the optimal adsorption range and is suitable for curing hexahedral workpieces of different sizes. The adjustable mechanism allows for convenient and rapid height adjustment of the UV curing lamp 400, adapting to curing various sizes of objects, greatly improving curing efficiency and making operation simpler and more convenient.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
