Technical Field
[0001] The utility model discloses a bearing steel ball coating device based on magnetron sputtering technology, and relates to the field of magnetron sputtering devices. Background Art
[0002] In modern industry, demand for high-performance bearings is growing in fields such as high-end CNC machine tools, precision instrumentation, new energy vehicles, and aerospace equipment. High-performance bearing steel balls must not only exhibit excellent wear and corrosion resistance, but also possess a highly uniform and consistent surface coating. However, existing technologies struggle to meet these requirements, severely hindering the development of related industries.
[0003] Magnetron sputtering technology, a mature surface coating method, has numerous applications for improving material surface properties. However, when applying magnetron sputtering technology to the coating of bearing steel balls, conventional equipment presents numerous challenges. For example, existing coating equipment often struggles to ensure uniform rotation of the steel balls, resulting in poor coating uniformity. Furthermore, the operating principle of magnetron sputtering equipment, which sputters upward, hinders its suitability for coating spherical samples, significantly limiting its use cases.
[0004] Therefore, developing a bearing steel ball coating device based on magnetron sputtering technology to solve the current problems, expand the use scenarios of upward sputtering magnetron sputtering equipment, and improve the coating quality and production efficiency of bearing steel balls has become a technical problem that needs to be solved urgently in this field.

[0005] The purpose of this utility model is to provide a bearing steel ball coating device based on magnetron sputtering technology, expand the use scenarios of upward sputtering magnetron sputtering equipment, and enable it to solve the problem of uneven surface coating when coating bearing steel balls.
[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:
[0007] The utility model is an external bearing steel ball coating device based on magnetron sputtering technology. The entire device is arranged in a sputtering chamber, and the device includes a base plate, a column, a motor compartment, a reduction motor, a roller, a wire, and an external power supply. The base plate is inverted and inserted into the sample holder of the upper magnetron sputtering device; the column is fixedly arranged on the base plate and connected to the motor compartment; the reduction motor is installed in the motor compartment and fixedly connected to the external power supply, and the reduction motor shaft is connected to the roller; one of the left and right sides of the roller that is not connected to the shaft is an open surface, so that the sputtered neutral target atoms can be better deposited on the bearing steel ball; an inclined baffle is provided at the tail of the roller arc surface to ensure that the bearing steel ball does not fall off when the roller is rotated by the motor shaft.
[0008] The purpose of the utility model and the solution to its technical problems can be further achieved by adopting the following technical measures:
[0009] The aforementioned device, including the base plate, columns, motor compartment, and rollers, was modeled in SolidWorks and then printed using stereolithography (SLA) 3D printing technology using resin.
[0010] The aforementioned device, the base plate, should have dimensions that match those of a sample holder in a magnetron sputtering device.
[0011] The aforementioned device, the column, has a solid structure inside.
[0012] The external power supply of the aforementioned device is a 12V DC power supply, and the reduction motor is a DC reduction motor with a rated voltage of 12V and an adjustable speed of 0-90r / min.
[0013] The aforementioned device, the motor compartment is matched with the aforementioned reduction motor, and a round hole is opened in the front of the motor compartment for the rotation shaft to pass through.
[0014] In the aforementioned device, the bearing steel ball coated roller has a diameter three times that of the coated bearing steel ball, and the width of the roller arc surface is 2-3 times that of the coated bearing steel ball, ensuring that the bearing steel ball can roll freely in the roller.
[0015] In the aforementioned device, an inclined baffle is provided at the tail end of the arc surface of the roller to ensure that the bearing steel balls will not fall off when rolling randomly in the roller while reducing the obstruction of the target particles.
[0016] The aforementioned device, external power supply, reduction motor and wires were obtained through commercial purchase channels, and the remaining parts were all made of resin materials and printed using a 3D printer.
[0017] With the help of the above technical scheme, the utility model of a bearing steel ball coating device based on magnetron sputtering technology has at least the following advantages and beneficial effects: the rest of the device except the external power supply and the reduction motor are printed with resin components, the production cost is low, and the size design can be flexibly adjusted according to the requirements of the magnetron sputtering equipment; the bearing steel ball coating roller rolls evenly under the action of the reduction motor, so that the bearing steel ball in the roller simultaneously revolves and rotates, so that the coating on the surface of the steel ball is uniform and stable.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following, in combination with the drawings and specific embodiments, describes in detail the specific implementation method, structure, characteristics and effects of a bearing steel ball coating device based on magnetron sputtering technology proposed by the present invention.
[0023] See also Figure 1 , which is an embodiment of the bearing steel ball coating device based on magnetron sputtering technology of the present invention, which includes a base plate 1, a column 2, a motor compartment 3, a roller 4, a reduction motor 5 and an external power supply 6.
[0024] See also Figure 1 , the base plate 1 is inserted into the sample holder of the sputtering equipment with the sampling facing upward, and is connected to the column 2, and the other end of the column 2 is connected to the motor compartment 3. One end of the motor compartment 3 is in an open state, for the reduction motor 5 to be placed therein, and the other end is open for the rotating shaft of the reduction motor 5 to pass through and connect to the roller 4. The end of the roller 4 connected to the reduction motor 5 is also open, and the other end is an open surface. The tail of the open end of the arc surface of the roller is provided with an inclined baffle to ensure that the bearing steel balls will not fall during the coating process. The reduction motor 5 and the external power supply 6 are connected by a wire 7, both of which are purchased through ordinary commercial channels. The speed of the reduction motor 5 can be adjusted to ensure that the bearing steel balls have a suitable revolution speed in the roller during the coating process, thereby improving the quality of the bearing steel ball coating and ensuring the uniformity of the bearing steel ball coating.
[0025] See also Figure 1 and Figure 2The base plate 1 and the column 2 support the entire device, so its interior adopts a solid structure. The reduction motor 5 and the external power supply 6 are both purchased from commercial materials. The external power supply adopts a 12V lithium-ion group with an external waterproof box. The reduction motor 5 adopts a DC reduction motor with a rated voltage of 12V, a diameter of 20mm, a total length of 65mm (of which the motor is 53mm long and the shaft is 12mm long), a rated torque of 10KG, and a speed of 0-90r / min to ensure that the coating of the bearing steel balls has a suitable orbital speed and the coating quality. The motor compartment 3 matches the reduction motor 5, and its dimensions are 25×25×55mm, with a wall thickness of 2mm. A circular hole with a diameter of 2mm is opened in the front of the motor compartment for the shaft to pass through. Similarly, a circular hole with a diameter of 2mm is opened on the surface where the roller 4 is connected to the shaft to make it tightly connected to the shaft. The diameter of the coated bearing ball roller 4 is three times the diameter of the coated bearing ball, and the width of the roller's arc surface is three times the diameter of the coated bearing ball. The wall thickness of the roller and the arc surface is 1mm, ensuring that the bearing ball can roll freely within the roller. A tilted baffle is installed at the end of the roller's arc surface. The baffle has a 60° inclination and a vertical height of no less than 50% of the diameter of the coated bearing ball. This ensures that the bearing ball does not fall during random rolling within the roller while reducing the obstruction of target particles.
[0026] The working principle of a steel ball coating fixture device based on magnetron sputtering technology in an embodiment of the present invention is as follows. The entire device operates under the support of the base plate 1 and the column 2. The external power supply 6 provides energy and power for the reduction motor 5. The roller 4 rotates evenly at a certain speed driven by the reduction motor 5, so that the bearing steel ball can fully roll randomly in the roller, thereby achieving the purpose of uniform coating of the bearing steel ball. The device has a simple structure and is easy to manufacture and use. Except for the reduction motor 5, the external power supply 6 and the wire 7, which are ordinary commercially purchased materials, the rest of the material is resin material and is printed by a stereolithography 3D printer.
