The anti -sticking vacuum coating rotating stand includes rotating disc assembly, revolution main rod, rotation hanging rod;The rotating disc assembly includes bottom disc, revolution disc, revolution gear, rotation gear, rotating main shaft. The rotating disc assembly is also provided with plane ball bearing, and the plane ball bearing is fixedly arranged above the bottom disc and supported in the inner ring of the lower surface of the revolution gear. The anti -sticking vacuum coating rotating stand provided by the utility model keeps the vertical angle of the rotating stand stable by setting the plane ball bearing to support the revolution gear horizontally, avoids the sticking caused by inclination, thereby improving the production efficiency;And because the angle of the revolution gear is stabilized, the uniformity of work piece coating is also improved, and the product yield is improved.

[0004] But the prior art still has great deficiencies, such as:

[0005] The traditional vacuum coating rotating stand only relies on the intermediate shaft and bearing to support rotation during operation, especially the rotating stand with rotation and revolution functions. Because the work piece rotates in the revolution process, its center of gravity changes randomly, so it will cause damage to the rotating shaft and bearing of the rotating stand, and the phenomenon of sticking, which affects the normal work of the coating rotating stand. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a vacuum coating rotating stand with anti -sticking function to solve the problems in the above background technology.

[0019] 1. The support assembly provided on the base can provide stable support for the edge of the rotating disc. In actual coating operation, the distribution of the workpieces to be coated is often difficult to be completely uniform, which can easily cause the center of gravity of the rotating disc to change. At this time, the support assembly can prevent the center of gravity of the rotating disc from deviating, so as to avoid that the rotating shaft and the bearing of the rotating disc bear excessive unbalanced force. If the rotating shaft and the bearing are subjected to unbalanced force for a long time, wear and deformation can easily occur, and the device can be seriously stuck. The stable support of the support assembly ensures that the rotating shaft and the bearing bear relatively uniform force, protects these key components, and enables the device to continuously and normally operate.

[0020] 2. The support assembly not only can support, but also can realize height adjustability through the first wedge block, the second wedge block and the bolt. The operator can drive the first wedge block to slide by screwing the bolt, push the ball seat to move up and down on the guide column by using the slope cooperation of the first wedge block and the second wedge block, and then level the rotating disc. Timely leveling operation can correct the inclination state of the rotating disc, prevent lateral force caused by inclination from causing additional burden on the rotating shaft and the bearing, reduce the risk of damage of the rotating shaft and the bearing, and avoid device sticking caused by component damage.

[0021] 3. The wear-resistant plate is fixed on the bottom surface of the rotating disc, reduces the wear of the contact part between the rotating disc and the support ball and the like, prolongs the service life of the rotating disc, and reduces the equipment maintenance cost. The protective cover prevents foreign matters from entering the rotating frame, avoids that the coating material is attached to the transmission component, ensures normal operation of the transmission component, and prolongs the service life of the transmission component.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0031] Embodiment one:

[0032] A vacuum coating rotary frame with anti-stuck function, which is mainly applied to vacuum coating equipment, can effectively avoid the phenomenon of sticking during operation, and ensure the smooth progress of coating work. The overall structure is mainly composed of base 1, sun gear 2, turntable 3, rotating rod 4, planetary gear 5, support assembly 6 and other components. Through the reasonable connection and cooperative work between each part, not only the stable rotation and uniform coating effect are realized, but also the problems such as change of the center of gravity of the turntable 3 are effectively solved, and the reliability and service life of the equipment are improved.

[0033] The base 1 is a stable platform as the support foundation of the whole vacuum coating rotary frame. The base 1 is usually made of high-strength metal materials, such as high-quality carbon steel or stainless steel, to ensure that it can bear the weight of the whole rotary frame and the workpiece to be coated. Its surface is precisely machined to ensure the flatness and precision of installing other components.

[0034] The sun gear 2 is fixedly arranged on the base 1 and is closely connected with the base 1 through bolt connection and other ways to ensure the stability of its position. The central shaft of the sun gear 2 is perpendicular to the base 1, providing stable support and transmission basis for the rotation of the subsequent turntable 3 and planetary gear 5.

[0035] The rotating disc 3 is rotatably arranged on the sun gear 2. Specifically, the rotating disc 3 has an axial hole adapted to the sun gear 2, and is rotatably arranged on the central shaft of the sun gear 2 through a high-precision bearing, so that the rotating disc 3 can rotate around the central shaft of the sun gear 2. This rotatable connection allows the rotating disc 3 to rotate smoothly under the support of the sun gear 2, and the use of the bearing greatly reduces the friction during rotation.

[0036] The rotating rod 4 is rotatably arranged on the rotating disc 3. The rotating rod 4 is evenly distributed on the circumference of the rotating disc 3. One end of each rotating rod 4 is connected to the rotating disc 3 through a bearing, so that the rotating rod 4 can rotate freely relative to the rotating disc 3. The number and distribution of the rotating rod 4 are reasonably designed according to the actual coating requirements and the size of the rotating frame to ensure that the workpiece to be coated can obtain uniform coating effect.

[0037] The planetary gear 5 is fixedly arranged on the rotating rod 4. The planetary gear 5 is fixed between the rotating rod 4 through key connection or interference fit, etc., to ensure that the planetary gear 5 can rotate with the rotating rod 4. At the same time, the planetary gear 5 is meshed with the sun gear 2, and the tooth shape is matched with the sun gear 2, to ensure the stability and accuracy of transmission. When the rotating disc 3 rotates, the planetary gear 5 will revolve around the sun gear 2 under the drive of the sun gear 2, and at the same time, it will also rotate around the rotating rod 4.

[0038] The coating workpiece can be installed on the rotating rod 4 for coating

[0039] A plurality of support assemblies 6 are fixedly arranged on the base 1. In this embodiment, the number of support assemblies 6 is three. Since three points can determine a plane, three sets of support assemblies 6 can provide good support for the rotating disc 3. Of course, according to actual needs, more sets of support assemblies 6 can also be provided for support. These support assemblies 6 are evenly distributed on the base 1 and support the edges of the rotating disc 3. During the rotation of the rotating disc 3, even if the center of gravity changes, the support assemblies 6 can also provide good support for the rotating disc 3, preventing the rotating shaft and bearing of the rotating disc 3 from being damaged due to the change of the center of gravity.

[0040] The support assembly 6 includes a ball seat 61 arranged on the base 1. The ball seat 61 is fixed on the base 1 by bolts or welding. The ball seat 61 has a spherical recess inside, and a support ball 611 is rotatably arranged in the recess. The support ball 611 is usually made of high-hardness and low-friction coefficient material. The top of the support ball 611 is in contact with the bottom surface of the rotating disc 3. When the rotating disc 3 rotates, the support ball 611 rolls in the ball seat 61, reducing the friction between the rotating disc 3 and the support ball 611, and improving the flexibility of rotation.

[0041] Example two:

[0042] In the embodiment, the first wedge 624 and other components are arranged to adjust the height of the support assembly 6 to level the rotating disc 3.

[0043] The support assembly 6 further comprises a support base 62 fixedly arranged on the base 1, which is fixed on the base 1 by bolts or welding. A plurality of guide columns 621 are fixedly arranged on the support base 62, which are perpendicular to the surface of the support base 62. The ball seat 61 is slidably arranged on the guide columns 621 through the guide holes matched with the guide columns 621, so that the ball seat 61 can slide up and down along the axial direction of the guide columns 621.

[0044] One end of the support base 62 is fixedly provided with a fixed plate 622, which is fixed with the support base 62 by welding. Threaded holes are formed in the fixed plate 622, and a bolt is rotatably arranged in the threaded hole. A first wedge 624 is slidably arranged on the support base 62, which can slide on the guide rail of the support base 62. One end of the bolt is rotatably connected with the first wedge 624. Specifically, a groove is formed in the first wedge 624, and the end of the bolt is embedded in the groove and connected through a bearing, so that the bolt can drive the first wedge 624 to slide on the support base 62 when the bolt rotates. A second wedge 612 is fixedly arranged on the ball seat 61, and the first wedge 624 and the second wedge 612 are in contact and cooperation. Their inclined surfaces are precisely machined and ground to ensure the precision of cooperation. When the first wedge 624 slides, it will push the ball seat 61 to move up and down along the guide column 621 through the cooperation with the inclined surface of the second wedge 612, so as to adjust the support height of the support ball 611.

[0045] A limiting plate 6211 is fixedly arranged on the guide column 621, which is firmly installed on the guide column 621 by welding or other methods. A spring 63 is sleeved on the guide column 621, which is arranged between the limiting plate 6211 and the ball seat 61. The key role of the spring 63 is to press the first wedge 624 and the second wedge 612.

[0046] During the entire working process of the support assembly 6, the cooperation of the first wedge 624 and the second wedge 612 is crucial, which realizes the height adjustment of the ball seat 61 through the inclined surface contact. However, in actual operation, factors such as vibration of the equipment and irregular force generated by rotation of the rotating disc 3 may cause looseness or relative sliding between the first wedge 624 and the second wedge 612, which may affect the precision and stability of the height adjustment of the ball seat 61, and even may cause the support assembly 6 to fail to work normally.

[0047] The presence of the spring 63 can effectively avoid the above-mentioned situation. It continuously exerts a pressure on the ball seat 61 towards the first wedge block 624, and since the second wedge block 612 is fixed on the ball seat 61, this makes the second wedge block 612 tightly press against the first wedge block 624, ensuring that the inclined surfaces of the two wedge blocks are always tightly fitted. This tight fitting ensures that when the bolt 623 drives the first wedge block 624 to slide, it can accurately and smoothly push the second wedge block 612 and the ball seat 61 to move, realizing accurate adjustment of the height of the support assembly 6

[0048] Embodiment three:

[0049] The gear ring 32 is fixedly arranged on the rotating disc 3, and the gear ring 32 is fixed together with the rotating disc 3 by high-strength bolts or welding, and the center of the gear ring 32 coincides with the center of the rotating disc 3, ensuring that the gear ring 32 can rotate together with the rotating disc 3. The gear shape of the gear ring 32 matches the subsequent transmission gear 9, and has good transmission performance.

[0050] The reducer 7 and the driving motor 8 are fixedly arranged on the base 1, and the driving motor 8 and the reducer 7 are installed at appropriate positions of the base 1 and fixed by bolts. The shaft of the driving motor 8 is fixedly connected with the input end of the reducer 7 through a shaft coupling, and the power output by the driving motor 8 is transmitted to the reducer 7 through the shaft, and then output from the output end of the reducer 7 after being reduced and increased in torque by the reducer 7. The gear 9 is fixedly arranged on the output end of the reducer 7, and the gear 9 is in meshing transmission with the gear ring 32. When the driving motor 8 starts, the power is transmitted to the gear 9 through the reducer 7, and the gear 9 drives the gear ring 32 to rotate, thereby driving the rotating disc 3 to rotate. The selection of the driving motor 8 and the reducer 7 is reasonably configured according to the load and rotating speed requirement of the rotating frame.

[0051] The wear-resistant plate 31 is fixedly arranged on the rotating disc 3, and the wear-resistant plate 31 is fixed on the bottom surface of the rotating disc 3 by welding or bolt connection. Its function is to reduce the wear of the surface of the rotating disc 3 and improve the service life of the rotating disc 3, especially in the parts in contact with the support ball 611 and other components, which can effectively prevent damage caused by friction.

[0052] A plurality of weight-reducing holes 33 are arranged on the rotating disc 3. The weight-reducing holes 33 are evenly distributed on the rotating disc 3. The purpose of arranging the weight-reducing holes 33 is to reduce the weight of the rotating disc 3, reduce the load of the driving motor 8, and also reduce the use of materials and cost. The shape and size of the weight-reducing holes 33 are optimized and designed to reduce the weight as much as possible under the premise of ensuring the structural strength of the rotating disc 3.

[0053] A protective cover 10 is fixed on the rotating disc 3 and is fixed on the rotating disc 3 by means of bolts or the like. The protective cover 10 protects the components on the rotating disc 3 and prevents the components from being polluted by external impurities during the coating process. A plurality of support rods 101 are fixed on the protective cover 10. One end of each support rod 101 is connected to the protective cover 10, and the other end of each support rod 101 is fixed with a support ring 102. The support ring 102 can enhance the structural strength of the protective cover 10 and ensure the stability of the protective cover 10 during use. The support rods 101 can also be used to place the workpieces to be coated.

[0054] Working principle:

[0055] When the vacuum coating work is needed, the driving motor 8 is started. The power output by the driving motor 8 is transmitted to the speed reducer 7 through the shaft. The speed reducer 7 reduces the speed and increases the torque of the power and then transmits the power to the gear 9 at the output end. Since the gear 9 and the gear ring 32 are engaged with each other, the rotation of the gear 9 drives the gear ring 32 to rotate, thereby driving the rotating disc 3 to rotate around the central axis of the sun gear 2. This power transmission mode ensures the stable operation of the rotating frame and the accurate speed control.

[0056] With the rotation of the rotating disc 3, the rotating rod 4 installed on the rotating disc 3 also rotates. Since the planetary gear 5 is fixed on the rotating rod 4 and the planetary gear 5 is engaged with the sun gear 2, the planetary gear 5 will revolve around the sun gear 2 under the drive of the sun gear 2, and at the same time, the planetary gear 5 will also rotate around the rotating rod 4. This movement mode of the planetary gear 5 can make the workpieces to be coated installed on the rotating rod 4 obtain more uniform coating effect during the vacuum coating process, because the workpieces can receive the deposition of the coating material in all directions during the revolution and rotation.

[0057] During the rotation of the rotating disc 3, the support assembly 6 plays an important role in supporting and stabilizing. The support ball 611 rolls in the ball seat 61 and is in contact with the bottom surface of the rotating disc 3, which reduces the friction and ensures the flexibility of the rotation of the rotating disc 3. At the same time, the height of the support assembly 6 can be adjusted according to the actual situation. The specific operation is to twist the bolt, and the rotation of the bolt drives the first wedge 624 to slide in the sliding groove of the support seat 62. The inclined surface of the first wedge 624 cooperates with the inclined surface of the second wedge 612 to push the ball seat 61 to move up and down on the guide column 621. In this way, the operator can level the rotating disc 3 to prevent the rotating disc 3 from deflecting and avoid damaging the rotating shaft and the bearing due to the inclination.

[0058] The wear-resistant plate 31 can reduce the wear of the surface of the rotating disc 3, prolong the service life of the rotating disc 3, and reduce the maintenance cost of the equipment. The weight-reducing holes 33 reduce the weight of the rotating disc 3, reduce the load of the driving motor 8, improve the operation efficiency of the entire rotating frame, and also reduce the energy consumption.

[0059] The protective cover 10 can prevent external impurities from entering the inside of the rotating frame, and protect the components on the rotating frame, especially prevent the coating material from adhering to the transmission components to affect the normal operation.

[0060] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
