Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An automatic spraying production line paint ultraviolet curing device includes a device base 1, a curing component 2 fixed on the upper surface of the device base 1, a purification mechanism for air purification on the upper surface of the curing component 2, and a curing mechanism for curing paint inside the curing component 2.

[0028] The purification mechanism includes two exhaust pipes 3, both of which are connected to the upper surface of the curing component 2. The ends of the two exhaust pipes 3 are connected to the purification component 31. A filter screen plate 34 is fixed to the inner wall of the purification component 31. An activated carbon plate 35 is fixedly connected to the purification component 31 above the filter screen plate 34. A fixing plate 32 is fixed inside the two exhaust pipes 3. An exhaust fan 33 is fixed inside the fixing plate 32 by screws. Two sets of mounting brackets 4 are fixed on both sides of the device base 1. Guide rollers 5 are rotatably connected to the inner walls of the two sets of mounting brackets 4 by bearings.

[0029] By adopting the above technical solution, before using the UV curing device of the automatic spraying production line, the device base 1 is first placed in a suitable position. The workpiece to be cured after spraying is placed on the guide roller 5 set on the mounting frame 4. Then, the workpiece is pushed so that it passes through the inside of the curing component 2 and is placed on another guide roller 5. The external conveying equipment transports the workpiece. Since harmful gases are generated during UV curing, the exhaust fan 33 set on the fixed plate 32 can draw the harmful gases into the exhaust pipe 3 and then discharge them into the purification component 31. Then, the impurities in the air are filtered by the filter screen 34, and the odors in the air are adsorbed by the activated carbon plate 35, thereby reducing the harm caused to workers by the harmful gases discharged into the air.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the curing mechanism includes two fixing members 6, both of which are fixed inside the curing component 2. One end of each fixing member 6 is fixed with a limit bearing 61. The inner wall of the limit bearing 61 is fixed with a mounting ring 62. Four ultraviolet curing lamps 63 are symmetrically installed inside the mounting ring 62. Both ends of the four ultraviolet curing lamps 63 are connected with fixing screws 64 that are threaded to the curing component 2. A driven gear ring 65 is fixed on the outer surface of the mounting ring 62. A drive gear 66 meshes with one side of the driven gear ring 65. The input end of the drive gear 66 is connected to a stepper motor 67 that is screwed to one of the fixing members 6.

[0031] By adopting the above technical solution, the ultraviolet curing lamp 63 installed in the mounting ring 62 generates UV light to cure the paint on the surface of the workpiece. The stepper motor 67 drives the drive gear 66 to mesh with the driven gear ring 65 to rotate, thereby driving the mounting ring 62 to rotate synchronously. At this time, the four ultraviolet curing lamps 63 in the mounting ring 62 move in a circle along the central axis of the workpiece, which can more evenly cure the paint and improve the curing effect. The limiting bearing 61 installed between the fixing part 6 and the mounting ring 62 can ensure the normal rotation of the mounting ring 62. By unscrewing the fixing screw 64, the ultraviolet curing lamp 63 can be disassembled and replaced.

[0032] Working principle: The conveying equipment transports the workpiece. The ultraviolet curing lamps 63 installed in the mounting ring 62 generate UV light to cure the paint on the surface of the workpiece. The stepper motor 67 drives the drive gear 66 to mesh with the driven gear ring 65 to rotate, which in turn drives the mounting ring 62 to rotate synchronously. At this time, the four ultraviolet curing lamps 63 in the mounting ring 62 move in a circle along the central axis of the workpiece. The normal rotation of the mounting ring 62 is ensured by the limit bearing 61 set between the fixing part 6 and the mounting ring 62. The ultraviolet curing lamps 63 can be disassembled and replaced by unscrewing the fixing screws 64. Since harmful gases are generated during UV curing, the exhaust fan 33 set on the fixing plate 32 can draw the harmful gases into the exhaust pipe 3 and then into the purification part 31. Then, the air impurities are filtered by the filter screen 34 and the odors in the air are adsorbed by the activated carbon plate 35.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
