Description

Technical Field

[0001] This utility model belongs to the field of vacuum coating technology, and in particular relates to a vacuum coating rotating device. Background Technology

[0002] Vacuum coating is a technique that deposits materials onto the surface of a substrate in a vacuum environment using physical or chemical methods to form a thin film, giving the coated part specific optical, electrical, and mechanical properties. When performing vacuum coating on a part, a rotating device is needed to rotate it at a uniform speed to adjust the position and angle of the part to make the coating more uniform and effective.

[0003] As disclosed in Utility Model No. CN221166727U, a vacuum coating rotary device relates to the field of rotary device technology. It includes a housing mechanism with a rotating mechanism inside. The rotating mechanism includes a rotating table, and gears are meshed with the outer wall of the rotating table. A fixing groove is formed on the top of the gears. In use, this utility model, under the action of the rotating mechanism, allows the material to be coated. First, the material is placed between two fixed plates and fixed. Then, the rotating table is driven to rotate by a motor, causing the material to rotate horizontally. Simultaneously, a second motor drives the material to rotate vertically. This structure and method allow the material to rotate in multiple directions during the coating process, resulting in a more uniform coating on the material surface and preventing insufficient coating, thus greatly improving the quality of the coating. However, this technical solution is applicable to parts with fixed dimensions, while different parts require coating have different dimensions. This presents a technical problem: it cannot be applied to parts of different sizes requiring vacuum coating, resulting in low economic efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a vacuum coating rotary device, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vacuum coating rotary device, comprising a base, and further comprising: a platform on the top of the base, a vacuum coating machine body on the top of the platform, a cover at the front end of the vacuum coating machine body, a vacuum pump on one side of the top of the vacuum coating machine body, a suction pipe at the input end of the vacuum pump, a rotating seat at the bottom of the interior of the vacuum coating machine body, a rotating mechanism at the bottom of the rotating seat, a column at the middle position of the top of the rotating seat, a connecting sleeve fitted around the column, brackets at both ends of the connecting sleeve, positioning screw holes on both sides of the column, fastening bolts inserted into both sides of the connecting sleeve, and a limit stabilizing component between the top of the column and the top of the interior side wall of the vacuum coating machine body.

[0007] Furthermore, the connecting sleeve can be raised and lowered outside the column, the positioning screw holes are arranged at equal intervals on both sides of the column, and one side of the fastening bolt is inserted into the interior of the positioning screw hole.

[0008] Furthermore, the suction tube is L-shaped, and the bottom end of the suction tube penetrates the middle position of the top of the vacuum coating machine body.

[0009] Furthermore, the rotating mechanism includes a servo motor, which is located at the middle position of the top of the base. The output end of the servo motor is provided with a shaft. A bushing is provided between the top of the platform and the middle position of the bottom of the vacuum coating machine body. The top of the shaft passes through the bushing and is fixedly connected to the middle position of the bottom of the rotating seat. A stable track is provided at the bottom of the vacuum coating machine body. Support rollers are provided on both sides and both ends of the bottom of the rotating seat. The support rollers are distributed in a ring at equal intervals at the edge of the bottom of the rotating seat. The bottom ends of the support rollers are embedded in the inner side of the stable track, and the support rollers can roll on the inner side of the stable track.

[0010] Furthermore, the limiting and stabilizing component includes a connecting column, which is disposed at the top of the column. A limiting slide rail is provided at the top of the inner side wall of the vacuum coating machine body. A connecting rod is provided on the outer side of the connecting column. A stabilizing slide is provided between the outer sides of the connecting rod. A silicon carbide lubricating coating is provided on the outer side of the stabilizing slide.

[0011] Furthermore, the connecting rods are provided in four sets, and the connecting rods are on the same horizontal plane. The stabilizing slide is annular, and the outer side of the stabilizing slide is embedded in the inner side of the limiting slide rail, and the stabilizing slide can slide inside the limiting slide rail.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model provides an adjustment and positioning component between the outer side of the column and the inner side of the bracket. During use, the height and spacing of the bracket are adjusted by adjusting the position of the connecting sleeve outside the column. After the bracket is properly positioned, the fastening bolts are inserted through both sides of the connecting sleeve and into the corresponding positioning screw holes and tightened to fix the connecting sleeve and the bracket. This allows for the application of vacuum coating processing on items of different sizes, improving the economic efficiency of the vacuum coating rotation device.

[0014] 2. This utility model provides a limiting and stabilizing component between the top of the column and the top of the inner side wall of the vacuum coating machine body. When the rotating device starts and drives the item to rotate inside the vacuum coating machine body, the connecting column rotates with the column and drives the stabilizing slide to slide inside the limiting slide rail via the connecting rod. This limits and stabilizes the column, preventing it from tilting due to centrifugal force during rotation, which could cause the hanging rack to tilt and drop the item requiring vacuum coating. At the same time, the silicon carbide lubricating coating makes the stabilizing slide smoother when sliding inside the limiting slide rail, thereby further improving the stability of the rotating device when it drives the item to rotate and ensuring the safety of the item during the vacuum coating process.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a vacuum coating rotating device, including a base 1, and further including: a platform 2 on the top of the base 1, a vacuum coating machine body 3 on the top of the platform 2, a cover 10 at the front end of the vacuum coating machine body 3, a vacuum pump 8 on one side of the top of the vacuum coating machine body 3, an "L"-shaped suction pipe 7 at the input end of the vacuum pump 8, and the bottom end of the suction pipe 7 penetrating the middle position of the top of the vacuum coating machine body 3, a rotating seat 4 at the bottom inside the vacuum coating machine body 3, a column 5 at the middle position of the top of the rotating seat 4, and a connecting sleeve 17 sleeved on the outside of the column 5, the connecting sleeve 17 being able to... External lifting and moving mechanism allows for adjustment of the height and spacing of the hanging brackets 18. Hanging brackets 18 are located at both ends of the connecting sleeve 17. Positioning screw holes 22 are located on both sides of the column 5, arranged at equal intervals. Fastening bolts 20 are inserted into both sides of the connecting sleeve 17, with one side of each bolt inserted into a positioning screw hole 22. After adjusting and positioning the hanging brackets 18, the fastening bolts 20 are passed through both sides of the connecting sleeve 17 and inserted into the corresponding positioning screw holes 22 for tightening. This secures the connecting sleeve 17 and the hanging brackets 18, allowing for the mounting of items of different sizes for vacuum coating processing, thus enhancing the vacuum coating effect. The economic benefits of the vacuum coating rotary device are as follows: A servo motor 11 is installed at the middle position of the top of the base 1, and a shaft 15 is installed at the output end of the servo motor 11. A bushing 16 passes through the middle position of the top of the platform 2 and the bottom of the vacuum coating machine body 3. The top of the shaft 15 passes through the bushing 16 and is fixedly connected to the middle position of the bottom of the rotating seat 4. After the workpiece to be vacuum coated is hung on the hanger 18, the cover 10 is closed, and the vacuum pump 8 is used to perform a vacuum operation inside the vacuum coating machine body 3 through the suction pipe 7. Then, the coating material is evaporated by the evaporator, causing it to sublimate into gaseous particles and be transported to the workpiece inside the vacuum coating machine body 3 for deposition. A solid film is formed, and when the workpiece is vacuum coated, the servo motor 11 is started to drive the shaft 15 to rotate, which in turn drives the rotating seat 4 to rotate, thus making the workpiece rotate and the coating more uniform. The bottom of the vacuum coating machine body 3 is provided with a stable track 12, and the two sides and two ends of the bottom of the rotating seat 4 are provided with support rollers 13. The support rollers 13 are distributed in a ring at equal intervals at the bottom edge of the rotating seat 4. The bottom end of the support rollers 13 is embedded in the inner side of the stable track 12, and the support rollers 13 can roll inside the stable track 12. When the rotating seat 4 rotates, the support rollers 13 roll in the stable track 12, which can stabilize the rotating seat 4 and the workpiece.

[0024] When in use, the position height and spacing of the bracket 18 can be adjusted by adjusting the position height of the connecting sleeve 17 outside the column 5 to accommodate different sizes of plated parts. After adjusting and positioning the bracket 18, the fastening bolts 20 are inserted through both sides of the connecting sleeve 17 and into the positioning screw holes 22 at the corresponding height to fix the connecting sleeve 17 and the bracket 18.

[0025] As a further implementation of this embodiment, such as Figure 1-4 As shown, a limiting and stabilizing assembly is provided between the top of the column 5 and the top of the inner sidewall of the vacuum coating machine body 3. The limiting and stabilizing assembly includes a connecting column 21, which is located at the top of the column 5. A limiting slide rail 9 is provided at the top of the inner sidewall of the vacuum coating machine body 3. Connecting rods 14 are provided on the outer side of the connecting column 21. There are four sets of connecting rods 14, and the connecting rods 14 are on the same horizontal plane. A ring-shaped stabilizing slide 6 is provided between the outer sides of the connecting rods 14. The outer side of the stabilizing slide 6 is embedded into the inner side of the limiting slide rail 9, and the stabilizing slide 6 can be located inside the limiting slide rail 9. When the column 5 rotates, the connecting rod 14 drives the stabilizing slide 6 to slide inside the limiting slide rail 9, which can stabilize the column 5, the hanger 18 and the plated parts. This prevents the hanger 18 from tilting and falling due to the centrifugal force when the column 5 rotates. The outer side of the stabilizing slide 6 is provided with a silicon carbide lubricating coating 19. The silicon carbide lubricating coating 19 makes the stabilizing slide 6 slide more smoothly inside the limiting slide rail 9, thereby further improving the stability of the rotating device when it drives the items to rotate and ensuring the safety of the items during the vacuum coating process.

[0026] When the rotating device starts and drives the item to rotate inside the vacuum coating machine body 3, the connecting column 21 rotates with the column 5 and drives the stabilizing slide 6 to slide inside the limiting slide rail 9 through the connecting rod 14, so as to limit and stabilize the column 5 and prevent the column 5 from tilting due to centrifugal force when rotating, which would cause the hanging rack 18 to tilt and fall off the item that needs vacuum coating. At the same time, the silicon carbide lubricating coating 19 makes the stabilizing slide 6 slide more smoothly inside the limiting slide rail 9.

[0027] Working Principle: When using the vacuum coating rotary device, first adjust the position and height of the connecting sleeve 17 outside the column 5 according to the workpiece to be vacuum coated, thereby adjusting the position, height, and spacing of the hanger 18. Then, insert the fastening bolts 20 through both sides of the connecting sleeve 17 and into the corresponding positioning screw holes 22 to tighten them, thus fixing the connecting sleeve 17 and the hanger 18. Next, hang the workpiece on the hanger 18. After hanging the workpiece to be vacuum coated on the hanger 18, close the cover 10 and use the vacuum pump 8 to perform a vacuum operation inside the vacuum coating machine body 3 through the suction pipe 7. Then, use the evaporator to evaporate the coating material, causing it to sublimate into gaseous particles, which are then transported to the workpiece inside the vacuum coating machine body 3 to deposit and form a solid film. Furthermore, when performing vacuum coating on the workpiece, the servo motor 11 is activated to drive the shaft 15 to rotate, thereby rotating the rotating seat 4. This causes the workpiece to rotate, making the coating more uniform. At the same time, the support roller 13 rolls within the stabilizing track 12 to stabilize the rotating seat 4 and the workpiece. The connecting column 21 rotates with the column 5 and drives the stabilizing slide 6 to slide inside the limiting slide rail 9 via the connecting rod 14, thereby limiting and stabilizing the column 5. This prevents the column 5 from tilting due to centrifugal force during rotation, which could cause the hanger 18 to tilt and drop the items requiring vacuum coating. Simultaneously, the silicon carbide lubricating coating 19 makes the stabilizing slide 6 slide more smoothly within the limiting slide rail 9, thus stably and safely driving the workpiece to rotate for uniform vacuum coating.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
