Description

Technical Field

[0001] The invention relates to the technical field of coating, and in particular to a vacuum coating device which is convenient for replacing workpieces. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metal materials under high vacuum conditions to evaporate and condense on the surface of the plated part to form a thin film.

[0003] When coating, the workpiece needs to be hung on the workpiece placement rack. In order to ensure the stability of the workpiece, the placement rack needs to be fixed. However, it is found that the existing vacuum coating device is manually fixed on the placement rack during use. After the coating is completed, it needs to be manually released before the workpiece can be replaced. The steps of replacing the workpiece are relatively cumbersome and the labor intensity is high, so it needs to be improved.

The bearing connection can reduce wear.

[0052] The use process of the present invention is as follows: when it is necessary to coat the surface of the workpiece, the workpiece is hung on the hooks on the two placement racks 5, and then the coating material is placed in the two placement shells 32, and then the four electric cylinders 10 are controlled to work, so that the movable plate 11 can be moved downward, and then the outer shell 30 is moved downward, so that the outer shell 30 can cover the outside of the right placement rack 5, and at the same time the outer shell 30 is in contact with the rubber ring 28, and then the vacuum pump 31 is controlled to work, so that the inside of the outer shell 30 can be evacuated to a vacuum, and then the two electron beam generators 33 are controlled to work, so that the electron beam will irradiate the coating material to heat it, and after reaching a certain temperature, the coating material can sublimate in a vacuum environment, and after the coating material sublimates, it can adhere to the surface of the workpiece to achieve vacuum coating.

[0053] When the moving plate 11 moves downward, the moving rod 14 and the piston 2 13 can also move downward. Then, under the action of the pipe 15 and the pipe 3 47, the piston 2 13 moves downward, so that the air in the box 2 12 can enter the box 3 42, thereby pushing the piston 3 43, the connecting rod 44, the sliding block 41, the fixed block 40, the prism 36, the connecting block 37 and the plurality of levers 1 38 to move leftward. When the housing 30 contacts the rubber ring 28, part of the lever 1 38 can move between two adjacent levers 2 39 (the lever 2 39 on the right side), and then the motor 48 is controlled to rotate forward. The forward rotation of the motor 48 drives the rotating shaft 3 49 to rotate. Since the sleeve 52 is connected to the rotating shaft 3 49 through a one-way bearing, the motor 48 is driven by the rotating shaft 3 49. When the machine 48 rotates forward, the sleeve 52 does not rotate, the rotation of the rotating shaft 3 49 drives the bevel gear 1 50 to rotate, the rotation of the bevel gear 1 50 drives the bevel gear 2 51 to rotate, the rotation of the bevel gear 2 51 drives the rotating shaft 2 35 to rotate, the rotation of the rotating shaft 2 35 drives the prism 36 to rotate, and the rotation of the prism 36 can rotate the connecting block 37 and multiple levers 1 38. Since the levers 1 38 and the levers 2 39 are staggered, when the levers 1 38 rotate, the levers 2 39 can be driven to rotate, so that the base block 6 on the right side rotates, and then the placement rack 5 on the right side rotates, so that the workpiece can be rotated in the shell 30 during coating, so that the coating material can be evenly adhered to the surface of the workpiece, thereby ensuring the quality of the coating.

[0054] When the coating of the workpiece on the right side placement rack 5 is completed, the electric cylinder 10 can be controlled to move the moving plate 11 upward and reset, and then the shell 30 will move upward and reset, and the moving rod 14 and the piston 2 13 will also move upward, so that the air in the box body 3 42 can return to the box body 2 12, and then the piston 3 43, the connecting rod 44, the sliding block 41, the fixed block 40, the prism 36, the connecting block 37 and the multiple levers 1 38 move to the right and reset, and then the motor 48 is controlled to reverse. Since the bevel gear 2 51 and the rotating shaft 2 35 are also connected through a one-way bearing, the rotating shaft 2 35 of the reversed motor 48 does not rotate, but the sleeve 52 will rotate. The rotation of the sleeve 52 drives the chain 54 to rotate, and the rotation of the chain 54 drives the rotating block 3 to rotate, so that the coating table 4 can be driven to rotate, and the motor 48 is controlled to make the coating table 4 rotate half a circle, so that the placement rack 5 on the right side can be moved to the bottom of the shell 30, and then the coating work is continued according to the same principle.

[0055] When the moving plate 11 moves downward to make the moving rod 14 and the piston 13 move downward, the air in the box 12 will also enter the box 1 7 under the action of the pipe 16, so that the piston 1 8 and the push rod 9 can be pushed upward. The upward movement of the push rod 9 can make the fixed assembly above the push rod 9 work. The working principle of the fixed assembly is described in detail below: the push rod 9 moves upward to contact the moving block 22, so that the moving block 22 can be pushed upward. The upward movement of the moving block 22 can make the two connecting rods 23 and the two protrusions 20 move upward. At the same time, the two springs 24 are compressed. Since the two protrusions 20 are embedded in the two spiral grooves 19, the two rotating shafts 17 can be rotated when the two protrusions 20 move upward. The rotation of the two rotating shafts 17 drives the two card blocks 18 to rotate, so that the two card blocks 18 can be moved from the two card grooves. After the workpiece is put away, the new rack 5 with the workpieces on it can be put on the base block 6. After the workpieces are put away, the coating work on the right side is almost finished. After the workpieces are put away, the moving rod 14 and the piston 13 will move upward according to the same principle, so that the air in the box body 7 can be sucked back. Then the piston 18 and the push rod 9 will move downward and reset. At this time, the moving block 22, the connecting rod 23 and the protrusion 20 can be moved downward under the action of the rebound of the two springs 24, so that the two rotating shafts 17 can be reversed. In this way, the two clamping blocks 18 will be clamped in the clamping groove again to fix the rack 5. In this way, the automatic fixing and automatic releasing of the rack 5 can be realized without manual operation. This makes it more convenient to replace the workpieces and reduces the labor intensity of the workers.
