Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating rotation technology, and in particular to a rotating structure for coating equipment. Background Technology
[0002] Vacuum coating technology first appeared in the 1930s, and industrial applications began in the 1940s and 1950s. Large-scale industrial production began in the 1980s. It has been widely used in industries such as electronics, aerospace, packaging, decoration, hot stamping and printing. Vacuum coating refers to the deposition of a certain metal or metal compound onto the surface of a material in the form of a gas phase in a vacuum environment. It belongs to the physical vapor deposition process.
[0003] Existing vacuum coating rotary devices can only rotate in one direction during use, resulting in uneven coating thickness on the material surface. Local areas are prone to being too thick or too thin, leading to low product qualification rate, frequent rework, and seriously affecting production quality. Utility Model Content

[0018] Example 1, as Figure 1-4 As shown, a rotating structure for a coating equipment includes a base 1, and a plurality of mounting holes 4 are circumferentially formed on the surface of the base 1.

The double rotating device 2 includes a first motor 201 fixedly installed on the surface of the base 1. A turntable 202 is fixedly installed on the output end of the first motor 201 via a coupling. Two support plates 203 are fixedly installed on the surface of the turntable 202. A threaded rod 204 is rotatably connected between the two support plates 203. A rotating wheel 205 is fixedly installed on the surface of the threaded rod 204. The threads on the surface of the threaded rod 204 are mutually opposite threads with the rotating wheel 205 as the center. A sliding rod 206 is fixedly installed between the two support plates 203. Two sliding mounting seats 207 are threadedly connected to the surface of the threaded rod 204. The sliding mounting seats 207 are slidably connected by the threaded rod 204 and the sliding rod 206. A vertical plate 208 is slidably inserted into the interior of each of the two sliding mounting seats 207. A rotating shaft 209 is rotatably connected to the surface of each of the two vertical plates 208. One end of the 09 is fixedly installed with a limiting sleeve 210. A second motor 211 is fixedly installed on the surface of one of the upright plates 208. The output end of the second motor 211 is fixedly connected to one of the rotating shafts 209 through a coupling. The first motor 201 is a 110 servo motor with a power of 500W, an adjustable speed of 0-30rpm, and a positioning accuracy of ±0.5°. The threaded rod 204 has a thread pitch of 2mm, and the left and right threads are symmetrically distributed. The internal thread accuracy of the sliding mounting seat 207 is 6g, and the clearance between it and the sliding rod 206 is ≤0.1mm. The synchronous movement deviation of the two sliding mounting seats 207 is ≤0.5mm. The clearance between the upright plate 208 and the sliding mounting seat 207 is ≤0.1mm. The inner wall of the limiting sleeve 210 is covered with a silicone pad to prevent scratches. The second motor 211 is a 60 servo motor with a power of 300W, an adjustable speed of 0-60rpm, and a synchronization error of ≤0.3s.
[0020] Reference Figure 3-4As shown in this embodiment: a fixing device 3 is provided on one side surface of the upright plate 208. The fixing device 3 includes a limiting plate 31 fixedly installed on one side surface of the upright plate 208. A limiting groove 32 is opened on the surface of the limiting plate 31. An L-shaped plate 33 is fixedly installed on one side surface of the sliding mounting base 207. The end of the L-shaped plate 33 away from the sliding mounting base 207 passes through the limiting groove 32. A bolt 35 is threadedly connected to one side surface of the limiting plate 31. A threaded hole 34 matching the bolt 35 is opened on one side surface of the vertical end of the L-shaped plate 33. The bolt 35 is an M6×20mm, 8.8 grade high strength bolt with a tightening torque of 10±1N・m. The depth of the threaded hole 34 is 15mm and the thread accuracy is 6H.
[0021] Working Principle: When using this device, first check whether the wiring between the first motor 201 and the second motor 211 is stable, whether the sliding fit between the threaded rod 204 and the sliding mounting base 207 is smooth, and whether the silicone pad on the inner wall of the limit sleeve 210 is intact. Ensure that there is no jamming or damage to any components to avoid malfunctions during the coating process. After the inspection is completed, the operator first uses the mounting holes 4 on the surface of the base 1 to fix the entire device in a suitable position inside the coating equipment, ensuring that the device is horizontal and stable. Then, according to the diameter of the cylindrical material to be coated, select the corresponding size limit sleeve. The upright plate 208 of the positioning sleeve 210 is inserted into the sliding mounting seat 207, so that the L-shaped plate 33 passes through the limiting groove 32 on the limiting plate 31. The bolt 35 is screwed into the threaded hole 34 of the L-shaped plate until it is tightened, thereby fixing the upright plate 208 and preventing it from loosening during rotation. Then, the cylindrical material is held and placed steadily between the two limiting sleeves 210. The arc-shaped inner wall of the limiting sleeve 210 initially fits against the outer wall of the material to form a pre-position. Then, the rotating wheel 205 is rotated, and the rotating wheel 205 drives the threaded rod 204 to rotate between the two support plates 203.Because the threads on the surface of the threaded rod 204 are mutually opposite threads centered on the rotating wheel 205, the two sliding mounting seats 207 connected by the surface threads will slide synchronously along the sliding rod 206 in the direction of approaching each other. The movement of the sliding mounting seats 207 drives the two upright plates 208 to approach synchronously, ultimately making the two limiting sleeves 210 tightly fit the two ends of the material. The silicone pad on the inner wall not only prevents the material from being pinched, but also enhances the friction, ensuring that the material is firmly clamped and preventing radial wobbling during rotation. After fixing, the first motor 201 is started. The output of motor 201 drives turntable 202 to rotate via a coupling, which in turn drives the entire clamping structure and material to rotate 360° horizontally, ensuring uniform coating in all circumferential areas of the material. Simultaneously, the second motor 211 is activated, and its output drives shaft 209 to rotate via a coupling. Shaft 209 drives limit sleeve 210 and the material to rotate 360° vertically, ensuring full contact between all axial parts of the material and the coating source. This bidirectional rotation works synergistically, eliminating coating blind spots caused by traditional unidirectional rotation. To improve the uniformity of the coating on the material surface, if it is necessary to change to a material of a different diameter, first rotate the wheel 205 in the opposite direction to separate the sliding mounting base 207 from the limiting sleeve 210, loosen the old material, and then loosen the bolt 35 to completely unscrew it from the threaded hole 34. At this time, the L-shaped plate 33 loses its limit in the limiting groove 32, and the upright plate 208 can be pulled out from the sliding mounting base 207. Replace it with an upright plate 208 with a limiting sleeve 210 of the corresponding size, and re-fix it according to the above steps to adapt to the new specification material. The operation is simple and quick. This device effectively improves its versatility. After coating is completed, the first motor 201 and the second motor 211 are turned off. After the material comes to rest, the rotating wheel 205 is rotated in the opposite direction to separate the limiting sleeve 210. The finished product is then removed, and any residual impurities inside the limiting sleeve 210 are cleaned to ensure accurate clamping during the next use. Through the above process, this device achieves multi-directional uniform coating of materials with the help of a dual-rotation device, and achieves rapid specification adaptation with the fixing device. This effectively solves the problems of uneven coating and poor adaptability of traditional devices, improving coating quality and production efficiency.
