Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a workpiece rack for coating machines and the coating machine. Background Art

[0002] The coating machine is an important surface treatment equipment. The workpiece holder is an important part of the coating machine, which is used to clamp the product so that the product can rotate at a constant speed around the central axis. When the workpiece passes through the target material, the film layer will be evenly coated.

[0003] The coating machine includes a single-door coating machine and a double-door coating machine. The workpiece rack of the single-door coating machine can be set in a container, and a motor is set vertically below the central rotating shaft to drive the workpiece rack directly at the central shaft of the workpiece rack. The workpiece rack of the double-door coating machine (so that the machine can clamp the workpiece on the other open door when one door is closed for coating, thereby improving the coating efficiency) needs to be set on the main door. In order to make the main door not too large, the double-door model generally adopts the design of the central rotating shaft at the edge of the main door. Therefore, the double-door coating machine cannot set a motor vertically below the central rotating shaft to directly drive the workpiece rack. Therefore, the workpiece rack of the existing double-door coating machine adopts side-rotation power input, and uses the input gear to directly drive the revolving large gear, which will produce an excessively large transmission ratio. The gear is too large, resulting in greater noise and vibration, and the transmission is not smooth, causing the workpiece to vibrate during the uniform rotation of the central axis. A film of uniform thickness cannot be formed on the surface of the workpiece, and thus the high-precision coating process requirements of the workpiece cannot be met. Utility Model Content

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The embodiment of the utility model provides a workpiece rack 1000 for a coating machine, which can be set on the coating machine to install the workpiece so that all parts of the workpiece are evenly coated. It can be understood that the coating machine is not only equipped with a workpiece rack, but also equipped with target materials, switch doors and other prior art features, which will not be repeated here.

[0039] like Figures 1 to 3 As shown, an embodiment of the utility model provides a workpiece rack 1000 for a coating machine, comprising a rack 100, a central shaft 200, a revolving gear 300, a rotating disk 400, a fixed gear ring 500, a workpiece mounting shaft 600 and a driving shaft 700.

[0040] like Figure 1 As shown, the frame 100 provides a mounting base for other components. The frame 100 is a door-shaped structure. The frame 100 is arranged on the ground or other fixed table and is arranged on the container (vacuum housing 2000) through a movable door hinge, and can seal the opening of the container (vacuum housing 2000); Figure 2 As shown, the rack 100 includes a base plate 180 .

[0041] like Figure 3 As shown, the central shaft 200 is vertically arranged, and the central shaft 200 is fixedly connected to the bottom plate 180. For example, the central shaft 200 is fixedly installed on the bottom plate 180 by bolts or welding, and the bottom plate 180 is located at the bottom of the integral frame 100. The revolving gear 300 is rotatably installed on the central shaft 200. For example, the revolving gear 300 is coaxially arranged with the central shaft 200, and the revolving gear 300 is rotatably installed on the central shaft 200 through a bearing, and the revolving gear 300 is arranged horizontally. For example, as Figure 7As shown, the central shaft 200 is a hollow shaft, and a resistance evaporation coating component or a sputtering coating component can be installed in the hollow part of the central shaft 200. The main components of the resistance evaporation component include: power supply, transformer, electrode and evaporation resistor. The resistance evaporation coating component uses resistance to heat the coating material (generally tungsten wire or molybdenum wire) to melt and then vaporize and evaporate. After condensation, it adheres to the substrate (the workpiece to be coated) with a relatively low temperature to form a film layer; compared with sputtering coating, resistance evaporation coating has a fast coating speed, a simple principle, and a lower operating cost, but the film layer has low adhesion and low purity, and is generally used to prepare decorative films with low functionality; the range of resistance evaporation coating materials is small, and it is only suitable for metals with low melting points, while sputtering coating can prepare film layers of any material (including refractory metals and non-metals).

[0042] like Figure 7 As shown, the rotating disk 400 is coaxially fixedly connected with the revolving gear 300, and the rotating disk 400 is horizontally arranged. The revolving gear 300 rotates to drive the rotating disk 400 to rotate. For example, the rotating disk 400 and the revolving gear 300 are fixedly connected by pins so that the rotating disk 400 and the revolving gear 300 are fixed in the rotation direction. For example, the rotating disk 400 is hollowed out to reduce the weight of the workpiece rack 1000 for the coating machine. In another embodiment, the rotating disk 400 is a solid disk structure with a hollowed out arrangement.

[0043] like Figure 4 and Figure 5 As shown, the inner ring diameter of the fixed gear ring 500 is larger than the tooth top circle diameter of the revolving gear 300. The fixed gear ring 500 is sleeved on the revolving gear 300, but a gap is provided between the fixed gear ring 500 and the revolving gear 300, and the height of the fixed gear ring 500 is smaller than the height of the revolving gear 300. The fixed gear ring 500 is coaxially arranged with the central axis 200. The fixed gear ring 500 is fixedly connected to the bottom plate 180, exemplarily, as shown in FIG. Figure 4 As shown, a fixing plate 510 and a fixing column 520 are arranged between the fixed gear ring 500 and the base plate 180, and the fixing plate 510 and the fixing column 520 are fixedly connected to the base plate 180, and the fixed gear ring 500 is fixedly connected to the fixing plate 510 and the fixing column 520, thereby making the fixed gear ring 500 fixedly connected to the base plate 180 through the fixing plate 510 and the fixing column 520.

[0044] like Figure 3 As shown, the drive shaft 700 is rotatably mounted on the base plate 180, and the drive shaft 700 is passed through the inner ring of the fixed gear ring 500 to avoid interference between the drive shaft 700 and the fixed gear ring 500. A drive gear 750 is fixedly connected to the drive shaft 700, and the drive shaft 700 and the revolving gear 300 are matched through the drive gear 750. The rotation of the drive shaft 700 and the drive gear 750 drives the revolving gear 300 to rotate.

[0045] By reducing the diameter of the revolving gear 300 and the gap between the revolving gear 300 and the driving gear 750, the matching accuracy of the revolving gear 300 and the driving gear 750 is improved, the noise and vibration in the transmission process are reduced, and the vibration of the workpiece on the workpiece mounting shaft 600 is reduced, so that the target material forms a uniform thin film on the surface of the workpiece, thereby improving the coating accuracy.

[0046] like Figure 3 As shown, the workpiece to be coated can be mounted on the workpiece mounting shaft 600; the workpiece mounting shaft 600 is rotatably mounted on the rotating disk 400, and the rotating disk 400 rotates to drive the workpiece mounting shaft 600 to rotate around the axis of the central axis 200 to drive the workpiece to rotate around the axis of the central axis 200, and at the same time, the workpiece mounting shaft 600 can rotate around its own axis to drive the workpiece to rotate around the axis of the workpiece mounting shaft 600; the axis of the workpiece mounting shaft 600 is parallel to the axis of the rotating disk 400, and the workpiece mounting shaft 600 is gear-driven with the fixed gear ring 500, as shown in FIG. Figure 6 As shown, during use, the rotation of the revolving gear 300 drives the rotating disk 400 to rotate, and the rotation of the rotating disk 400 drives the workpiece mounting shaft 600 to rotate around the axis of the central axis 200. At the same time, the workpiece mounting shaft 600 cooperates with the fixed gear ring 500 gear to make the workpiece mounting shaft 600 rotate during the rotation around the axis of the central axis 200, so as to realize that the workpiece rotates around the axis of the workpiece mounting shaft 600 while rotating around the central axis 200, so that all parts of the workpiece are evenly coated.

[0047] like Figure 5 As shown, in one embodiment, a plurality of workpiece mounting shafts 600 are provided and the plurality of workpiece mounting shafts 600 are circumferentially distributed around the axis of the rotating disk 400 to increase the number of workpieces mounted on the workpiece rack 1000 for the coating machine and improve the coating efficiency. Exemplarily, the plurality of workpiece mounting shafts 600 are gear-driven with the fixed gear ring 500 at the same time.

[0048] like Figure 3 As shown, in one embodiment, the workpiece holder 1000 for a coating machine further includes a mounting seat 800 and a shaft sleeve 850 .

[0049] The mounting seat 800 is fixedly connected to the rotating disk 400 , and the rotating disk 400 rotates to drive the mounting seat 800 to rotate.

[0051] like Figure 3 As shown, in one embodiment, the rotating disk 400 is horizontally arranged, and the rotating disk 400 has two end surfaces parallel to the horizontal direction, and the two end surfaces are respectively a first end surface 420 and a second end surface 440. Figure 6 As shown, the first end surface 420 is located on the side of the rotating disk 400 close to the bottom plate 180, as shown in FIG. Figure 7 As shown, the second end surface 440 is located on the side of the rotating disk 400 away from the bottom plate 180; the revolving gear 300 is located on the side of the first end surface 420. Figure 3 As shown, in one embodiment, the driving gear 750 is located on a side close to the first end surface 420. Figure 6 As shown, in one embodiment, the first transmission gear 880 is located on one side of the first end surface 420 .

[0052] During use, the workpiece is mounted on the workpiece mounting shaft 600, and the workpiece is located on the side of the second end face 440 of the rotating disk 400, while the revolving gear 300 and the driving gear 750 that drive the rotating disk 400 to rotate are located at one end of the first end face 420. The workpiece is separated from the transmission structure by the rotating disk 400, which can to a certain extent prevent vibration from being transmitted to the workpiece through media such as air, thereby reducing the vibration of the workpiece and making the coating on the surface of the workpiece more uniform.

[0053] In some embodiments, the workpiece rack for coating also includes a lining plate, which is a thin plate detachably arranged on the rack 100, and the lining plate can separate the workpiece from the above-mentioned transmission structure. If the film layer is directly coated on the inner parts of the vacuum chamber for a long time, the film layer on the inner parts of the vacuum chamber will become thicker and thicker, affecting the use, and at the same time, there may be gas hidden in the film layer, affecting the pumping speed; the lining plate can prevent the film layer from being directly coated on the inner parts of the vacuum chamber, and the lining plate can be removed and cleaned regularly to ensure the cleanliness of the inner parts of the vacuum chamber and the pumping speed.

[0054] like Figure 6As shown, in one embodiment, the workpiece rack 1000 for the coating machine also includes a driving assembly, and the driving assembly includes a driving motor 900; the driving motor 900 cooperates with the driving shaft 700 with a belt drive, and the driving motor 900 and the driving shaft 700 adopt a flexible transmission mode of belt drive, which can further avoid the vibration caused by mechanical transmission. Exemplarily, a driving pulley is fixedly provided on the output shaft of the driving motor 900, and a driven pulley is fixedly provided on the driving shaft 700. The driving pulley and the driven pulley are connected by a transmission belt for belt drive.

[0056] In some embodiments, a support leg is provided below the rack 100, and the support leg is used to lift the rack 100 relative to the ground to prevent the rack 100 from being corroded by moisture on the ground.

[0059] An embodiment of the utility model also provides a coating machine, including a coating machine workpiece rack 1000 and a coating machine body as in any of the above embodiments, the coating machine body can coat the workpiece to be coated, and the coating machine workpiece rack 1000 is used to provide an installation position for the workpiece to be coated.

[0060] The coating machine body includes a vacuum shell 2000, which has an opening. The frame 100 of the coating machine workpiece rack 1000 is hinged to the vacuum shell 2000. The coating machine workpiece rack 1000 can enter the vacuum shell 2000 from the opening and seal the opening. The workpiece on the coating machine workpiece rack 1000 can be coated in the vacuum shell 2000.

[0061] like Figure 8As shown, in one embodiment, two workpiece racks 1000 for the coating machine are provided, and the two workpiece racks 1000 for the coating machine are provided on both sides of the opening, and the two workpiece racks 1000 for the coating machine enter the vacuum housing 2000 alternately. For the convenience of description, the two workpiece racks 1000 for the coating machines are named as the first workpiece rack 2100 and the second workpiece rack 2200 respectively. The workpiece to be coated is installed on the first workpiece rack 2100. The first workpiece rack 2100 first enters the vacuum shell 2000 from the opening to coat the workpiece. During the coating of the first workpiece rack 2100, the workpiece to be coated is installed on the second workpiece rack 2200. After the coating of the workpiece on the first workpiece rack 2100 is completed, the first workpiece rack 2100 is removed from the vacuum shell 2000, and the second workpiece rack 2200 is sent into the vacuum shell 2000 to coat the workpiece on the second workpiece rack 2200.

The working process is repeated in this way to improve the coating efficiency.

[0062] In another embodiment, the coating machine body includes a film thickness detection component, which includes a central processing unit, a vibration transmitting unit and a vibration receiving unit. The central processing unit can control the vibration transmitting unit to emit vibration, and the vibration receiving unit can convert the detected vibration signal into an electrical signal and transmit it to the central processing unit.

The vibration transmitting unit abuts against the workpiece that has been coated, and the vibration transmitting unit vibrates the workpiece. The vibration receiving unit abuts against the workpiece that has been coated, and the vibration receiving unit is used to receive the vibration of the workpiece. The central processing unit electrically connects the vibration transmitting unit and the vibration receiving unit. When the vibration is transmitted from the coated film body to the workpiece, the propagation speed of the vibration will change. When the vibration is transmitted from the workpiece to the coated film body, the propagation speed of the vibration will also change.
