Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a fast cooling vacuum coating machine. Background Art

[0002] A vacuum coating machine is a device used to form a thin film on the surface of a material. It deposits solid or gaseous materials on a substrate through processes such as evaporation, sputtering, ion plating or chemical reaction in a vacuum environment to form a thin film layer with specific functions and properties. Vacuum coating machines are widely used in optical films, metal coatings, ceramic coatings, electronic components, solar cells, anti-reflective coatings, hard coatings and other fields. By controlling the parameters in the coating process, such as temperature, pressure, material composition and deposition rate, different types of thin films can be achieved to meet the requirements of different applications.

[0003] At present, the existing vacuum coating machine with heat dissipation equipment (such as patent number: CN214736042U) discloses a vacuum coating machine with heat dissipation equipment. The scheme is a vacuum coating machine with heat dissipation equipment, including a vacuum coating machine body, a rotating storage rack is provided in the vacuum coating machine body, a driving device is connected to the bottom end of the rotating storage rack, an air inlet pipe is provided on the lower side of the right wall of the vacuum coating machine body, a first vacuum valve is provided on the air inlet pipe, and an air blower is connected to the outside of the air inlet pipe.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] The coating machine often cools and solidifies the object to be coated through a heat sink. However, when dissipating heat, the running coating machine may splash some coating liquid onto the heat sink, causing the coating splash material to accumulate on the fan surface, making it difficult to dissipate heat, thereby reducing the heat dissipation effect of the fan. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the utility model provides a fast-cooling vacuum coating machine, which solves the technical problem that the coating machine often cools and solidifies the object to be coated through a heat dissipation device, but when dissipating heat, the running coating machine may splash some coating liquid onto the heat dissipation device, causing the coating splashed material to accumulate on the fan surface, resulting in heat being difficult to dissipate, thereby reducing the heat dissipation effect of the fan.

[0008] (II) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A fast cooling vacuum coating machine includes a device body. The fast cooling vacuum coating machine is also provided with a cooling mechanism, including a connecting plate, a fan, a movable plate, a synchronous chain and two threaded rods. The rear surface of the device body is fixedly connected with the connecting plate, and the rear surface of the device body is also fixedly connected with the fan. The right surface of the connecting plate is provided with a groove, and the connecting plate and the movable plate are movably connected. The right surface of the movable plate is provided with a connecting frame, and the right surface of the connecting frame is fixedly connected to the inner wall of the device body. The right surface of the movable plate is provided with two threaded grooves, and the movable plate is threadedly connected with the two threaded rods.

[0011] Preferably, the left surface of the connection frame is penetrated by two holes one corresponding to the positions of the threaded rods, and the two threaded rods pass through the hole one to be rotatably connected to the inner wall of the device body.

[0012] Preferably: a second hole is penetrated through the right surface of the device body, and a fixing ring is fixedly connected to the right surface of the device body, a motor is fixedly connected to the right surface of the fixing ring, and the output port of the motor passes through the second hole and is fixedly connected to the right surface of the threaded rod at the lower end.

[0013] Preferably, a driven sprocket is arranged inside the connection frame, and the threaded rod located at the upper end is fixedly connected to the driven sprocket.

[0014] Preferably, a driving sprocket is arranged inside the connection frame, and the threaded rod located at the lower end is fixedly connected to the driving sprocket.

[0015] Preferably, a synchronous chain is arranged inside the connection frame, the synchronous chain is meshed and connected with the driven sprocket, and the synchronous chain is also meshed and connected with the driving sprocket.

[0016] (III) Beneficial effects

[0017] 1. When the coating machine finishes working, start the motor, and the motor drives the threaded rod at the lower end to rotate. At this time, the driving sprocket and the driven sprocket will drive the threaded rod at the upper end to rotate synchronously. Since the movable plate does not rotate, the movable plate will move. The movement of the movable plate will drive the heat dissipation fan to the inside of the device body. When the heat dissipation is completed, control the motor to output in reverse, so that the movable plate isolates the device body from the heat dissipation fan, avoiding the possibility that the running coating machine may splash some coating liquid onto the heat dissipation device, so that the heat dissipation effect of the fan is no longer affected.

[0018] 2. The driving sprocket and the driven sprocket are both located inside the connecting frame, which protects the driving sprocket and the driven sprocket, thereby preventing the moving plate from colliding with the driving sprocket and the driven sprocket when the motor drives the moving plate to move in the opposite direction, thereby increasing the service life of the driving sprocket and the driven sprocket.

[0025] The embodiment of the present application provides a fast-cooling vacuum coating machine, which effectively solves the technical problem that the coating machine often cools and solidifies the object to be coated through a heat dissipation device, but when dissipating heat, the running coating machine may splash some coating liquid onto the heat dissipation device, causing the coating splashed material to accumulate on the surface of the fan, resulting in heat being difficult to dissipate, thereby reducing the heat dissipation effect of the fan. When the coating machine finishes working, the motor is started, and the motor drives the threaded rod at the lower end to rotate. At this time, the driving sprocket and the driven sprocket drive the threaded rod at the upper end to rotate synchronously. Since the movable plate does not rotate, the movable plate will move. The movement of the movable plate will cause the heat dissipation fan to act on the inside of the device body. When the heat dissipation is completed, the motor is controlled to output in reverse, so that the movable plate isolates the device body from the heat dissipation fan, thereby avoiding the possibility that the running coating machine splashes some coating liquid onto the heat dissipation device, so that the heat dissipation effect of the fan is no longer affected.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the coating machine often cools and solidifies the article to be coated through the heat dissipation device, but when dissipating heat, the coating machine in operation may splash some coating liquid onto the heat dissipation device, causing the coating splash material to accumulate on the surface of the fan, resulting in heat that is difficult to dissipate, thereby reducing the heat dissipation effect of the fan. The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides a fast cooling vacuum coating machine, including a device body 1, the fast cooling vacuum coating machine is also provided with a cooling mechanism, including a connecting plate 2, a fan 3, a movable plate 12, a synchronous chain 6 and two threaded rods 10, the rear surface of the device body 1 is fixedly connected with the connecting plate 2, and the rear surface of the device body 1 is also fixedly connected with the fan 3, the right surface of the connecting plate 2 is provided with a groove 11, the connecting plate 2 is movably sleeved with the movable plate 12, and the right surface of the movable plate 12 is provided with a connecting Frame 7, the right surface of the connecting frame 7 is fixedly connected to the inner wall of the device body 1, two thread grooves 13 are provided on the right surface of the movable plate 12, and the movable plate 12 is threadedly sleeved with the two threaded rods 10, and the driving sprocket 15 and the driven sprocket 14 are both located inside the connecting frame 7, and the connecting frame 7 will protect the driving sprocket 15 and the driven sprocket 14, avoiding the collision of the movable plate 12 with the driving sprocket 15 and the driven sprocket 14 when the motor 5 drives the movable plate 12 to move in the reverse direction, thereby improving the service life of the driving sprocket 15 and the driven sprocket 14.

[0029] The left surface of the connecting frame 7 is penetrated by two holes 8 corresponding to the positions of the threaded rods 10. Both threaded rods 10 pass through the hole 18 and are rotatably connected to the inner wall of the device body 1. The right surface of the device body 1 is penetrated by a hole 29, and a fixing ring 4 is fixedly connected to the right surface of the device body 1. The right surface of the fixing ring 4 is fixedly connected to a motor 5. The output port of the motor 5 passes through the hole 29 and is fixedly connected to the right surface of the threaded rod 10 at the lower end. A driven sprocket 14 is arranged inside the connecting frame 7, and the threaded rod 10 at the upper end is fixedly connected to the driven sprocket 14. When the coating machine finishes working, the motor 5 is started, and the motor 5 drives the threaded rod 10 at the lower end to rotate. At this time, the driving sprocket 15 and the driven sprocket 14 will drive the threaded rod 10 at the upper end to rotate synchronously. Since the movable plate 12 does not rotate, the movable plate 12 will move.

[0030] A driving sprocket 15 is provided inside the connecting frame 7, and the threaded rod 10 at the lower end is fixedly connected to the driving sprocket 15. A synchronous chain 6 is provided inside the connecting frame 7, and the synchronous chain 6 is meshed and connected with the driven sprocket 14, and the synchronous chain 6 is also meshed and connected with the driving sprocket 15.

[0031] Working principle:

[0032] When the coating machine finishes working, the motor 5 is started, and the motor 5 drives the threaded rod 10 at the lower end to rotate. At this time, the driving sprocket 15 and the driven sprocket 14 will drive the threaded rod 10 at the upper end to rotate synchronously. Since the movable plate 12 does not rotate, the movable plate 12 will move. The movement of the movable plate 12 will cause the heat dissipation fan 3 to act on the inside of the device body 1. When the heat dissipation is completed, the motor 5 is controlled to output in the reverse direction, so that the movable plate 12 isolates the device body 1 from the heat dissipation fan 3, thereby preventing the running coating machine from splashing some coating liquid onto the heat dissipation device, so that the heat dissipation effect of the fan 3 is no longer affected. The driving sprocket 15 and the driven sprocket 14 are both located inside the connecting frame 7. The connecting frame 7 will protect the driving sprocket 15 and the driven sprocket 14, thereby preventing the moving plate 12 from colliding with the driving sprocket 15 and the driven sprocket 14 when the motor 5 drives the moving plate 12 to move in the reverse direction, thereby improving the service life of the driving sprocket 15 and the driven sprocket 14.
