Description

Technical Field

[0001] The invention relates to the technical field of coating equipment, in particular to a rotary table type coating equipment. Background Art

[0002] Coating equipment plays a vital role in modern industry and is widely used in automobile manufacturing, construction engineering, and home appliance production. Its main function is to coat the surface of products to improve their aesthetics, durability, and corrosion resistance. With the continuous advancement of technology, coating equipment has also undergone significant changes, from traditional manual spraying to today's automated spraying systems.

[0003] When painting parts, it is often common to manually rotate the turntable, which makes it difficult to ensure a constant and uniform rotation speed. In the actual painting process, the turntable speed can easily fluctuate due to human factors, resulting in different coverage of the paint sprayed by the spray gun on the surface of the parts, which in turn causes uneven coating thickness. Inconsistent coating thickness not only affects the flatness and aesthetics of the product appearance, but also weakens the product's protective performance. Once the coating thickness does not meet the standard or there is local non-coating, the product is prone to corrosion, wear and other damage during use, which significantly shortens its service life and reduces the product's competitiveness in the market. Summary of the invention

[0004] The purpose of the present invention is to provide a turntable type coating equipment, which achieves the effect of automatically rotating and adjusting the placement table by setting an adjustment device, and the parts to be coated fixed on the placement table can continuously change their positions, so that the spray head does not need to be frequently and drastically moved, and the coating can be evenly sprayed on various surfaces of the parts, greatly improving the coating efficiency.

[0038] like Figure 6 and Figure 7As shown, the clamping device 4 includes three mounting grooves 401, and the three mounting grooves 401 are all opened on the surface of the placing table 306. The inner surface of the mounting groove 401 is fixedly connected with two fixing rods 402, and the outer cylindrical surface of the two fixing rods 402 is slidably connected with a slide 403, and one side of the slide 403 is fixedly connected with a rectangular plate 404, and a plug rod 405 is slidably inserted in the rectangular plate 404. A plurality of limiting grooves are opened at the bottom of the mounting groove 401, and one end of the plug rod 405 is fixedly connected with an elliptical block 406, and one side of the slide 403 is fixedly connected with an anti-slip pad 409. The outer cylindrical surface of 05 is covered with a first spring 407, and the two ends of the first spring 407 are respectively fixedly connected to the elliptical block 406 and the rectangular plate 404. The elastic force of the first spring 407 drives the insertion rod 405 to slide in the rectangular plate 404 and automatically insert into the limiting groove at the bottom of the installation groove 401.

[0039] like Figure 8 As shown, the driving device 5 includes a fixed frame 501, which is fixedly connected to the surface of the base 1, and a second servo motor 502 is fixedly connected to one side of the fixed frame 501, and a screw rod 503 is fixedly connected to the output end of the second servo motor 502. The outer cylindrical surface of the screw rod 503 is threadedly connected to a connecting block 504, and one side of the connecting block 504 is fixedly connected to the nozzle 2. A limiting rod 505 is fixedly connected to the surface of the fixed frame 501, and the connecting block 504 is slidably connected to the outer cylindrical surface of the limiting rod 505. The screw rod 503 drives the connecting block 504 on the outer cylindrical surface of the limiting rod 505 to prevent the nozzle 2 from rotating with the rotation of the screw rod 503.

[0040] The specific working principle of the present invention is: When the operator adjusts the parts on the surface of the placement table 306, by starting the first servo motor 302, the first servo motor 302 drives the gear 303 to rotate, the gear 303 drives the gear ring 305 to rotate, the gear ring 305 drives the connecting rod 304 to rotate, and the connecting rod 304 drives the placement table 306 to rotate. At the same time, the placement table 306 drives the sliding rod 308 to slide on the inner wall of the slide groove 307, so that the placement plate is more stable during the rotation process. When the gear 303 rotates, it will continuously contact the lubrication wheel 311. During the contact, the lubricating oil on the surface of the lubrication wheel 311 will adhere to the surface of the gear 303 to lubricate the surface of the gear 303, and prevent the gear 303 and the gear ring 305 from being worn out for a long time and causing rotation jamming, thereby achieving the effect of automatically rotating and adjusting the placement plate, and the parts to be painted fixed on the placement table 306 can continuously change their positions, so that the nozzle 2 does not need to move frequently and significantly, and can evenly spray the paint on various surfaces of the parts, thereby greatly improving the coating efficiency. At the same time, compared with the manual rotation of the placement table 306, the rotation driven by the first servo motor 302 is more stable and uniform, which can ensure the consistency of coating thickness and effectively improve the coating quality. Moreover, by precisely controlling the rotation speed and rotation angle of the first servo motor 302, it can flexibly adapt to the requirements of different coating processes for the rotation speed and angle of parts, thereby enhancing the versatility and applicability of the equipment.

[0041] When the operator clamps the parts, he first places the parts on the surface of the placement table 306, and then pushes the slide 403 to slide on the outer cylindrical surface of the fixed rod 402 until the parts are limited. At this time, the elastic force of the first spring 407 drives the insertion rod 405 to slide in the rectangular plate 404 and automatically insert into the limiting groove at the bottom of the installation groove 401, so as to achieve the effect of clamping parts of different sizes. There is no need to frequently replace complex fixtures, and it can meet the coating needs of turntable parts of various sizes. Whether it is a small precision part or a larger part, it can be firmly fixed on the placement table 306 to ensure that the parts will not be displaced due to the impact force generated by the rotation of the turntable or the spray gun during the coating process, thereby ensuring the stability of the coating quality and avoiding problems such as uneven coating thickness or spray leakage due to the shaking of the parts.

[0042] When the operator adjusts the position of the nozzle 2, by starting the second servo motor 502, the second servo motor 502 drives the screw rod 503 to rotate, and the screw rod 503 drives the connecting block 504 to move. At this time, the connecting block 504 slides on the outer cylindrical surface of the limit rod 505, and the connecting block 504 drives the nozzle 2 to move horizontally, thereby achieving the effect of adjusting the nozzle 2, enhancing the adaptability of the equipment to diversified coating tasks, and greatly improving the working efficiency and practicality of the turntable coating equipment.
