Description

Technical Field

[0001] The present invention relates to the field of vacuum coating, and particularly to a transmission structure of a PGTVD vacuum coating equipment. Background Art

[0002] PGTVD, namely Pressurize Gas Transport Vectored Deposition, refers to pressurizing the vaporized coating material to increase its deposition speed. Through pressurized gas transport, the coating material can be deposited on the surface of the substrate with high quality and high uniformity. Among them, a transmission structure is also required when the PGTVD vacuum coating equipment is working. The transmission structure can be used to drive and convey the workpiece to be coated.

[0003] It is found that the existing transmission structure only has the function of driving and conveying the workpiece during use, and does not have the function of cooling the workpiece. Since the temperature of the workpiece itself is relatively high after the coating is completed, it is easy to be scalded when manually taking the material after the coating is completed. Therefore, it needs to be improved.

By designing the stabilizing component, the coating rack 11 can be automatically fixed when the workpiece moves from the left side to the right side of the device, so that the coating rack 11 can be prevented from shaking when the material is deposited on the workpiece at high speed during coating;

[0044] Among them, in order to achieve the purpose of rotating the coating rack 11, the present device adopts the following technical solution: A U-shaped groove 45 is formed on the base block 9. A rotating shaft two 46 is arranged in the U-shaped groove 45. L-shaped rods 47 are fixedly connected to both sides of the rotating shaft two 46. The two L-shaped rods 47 are respectively slidably arranged in the U-shaped groove 45. Springs 48 are fixedly connected to the tops of both of the two L-shaped rods 47. The tops of the two springs 48 are fixedly connected to the top of the U-shaped groove 45. A U-shaped frame 49 is fixedly connected to the bottom of the transmission table 8. The rotating shaft two 46 penetrates through the U-shaped frame 49 and is in movable contact with it. An iron block 50 is fixedly connected to the bottom end of the rotating shaft two 46.

A rotating shaft three 55 is fixedly connected to the output shaft of the motor two 54. The rotating shaft three 55 penetrates through the top of the frame 1 and is connected to it through a bearing. A magnet 56 is fixedly connected to the top end of the rotating shaft three 55. Components such as the motor two 54, the rotating shaft three 55, the magnet 56, and the iron block 50 can make the coating rack 11 rotate, so as to ensure uniform coating;

[0045] Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: The rotating plate 16 is connected to the housing 15 through a bearing. The reciprocating lead screw one 18 is connected to the rotating plate 16 and the L-shaped plate 17 through bearings. The rotating shaft one 27 is connected to the housing 15 and the support rod 14 through bearings. Connecting through bearings can reduce wear.

[0046] The usage process of the present invention is as follows: When the workpiece needs to be vacuum coated, hang the workpiece on the hook of the coating rack 11. Then control the four electric push rods 4 to move the vacuum chamber 2 upward. Then control the two electric slide rails 6 to work to move components such as the two sliders 7, the transmission table 8, and the base block 9 to the right until the coating rack 11 moves below the vacuum chamber 2. Subsequently, control the electric push rod 4 to move the vacuum chamber 2 downward to cover the outside of the coating rack 11 until the vacuum chamber 2 contacts the rubber ring 13. Then control the vacuum chamber 2 to work to carry out the coating work.

[0047] Among them, when components such as the two sliders 7, the transmission table 8, and the base block 9 move to the right, the second gear 41 will mesh with the toothed plate 43. When meshing, the reciprocating lead screw two 37 will rotate, so that the sliding seat two 38 and the two push blocks 40 will first move backward, and then under the action of the two triangular blocks 39, the two rotating rods 34 can be squeezed to make the two rotating rods 34 rotate around the two connecting rods 33 as the rotation axes. At the same time, the two torsion springs 36 undergo elastic deformation. The rotation of the two rotating rods 34 can make the two clamping blocks 35 open outward, thereby applying pressure to the coating rack 11, and further fixing the coating rack 11. In this way, it can be realized that the coating rack 11 is automatically fixed during the process of moving to the right. In this way, when the material is deposited on the workpiece at high speed during coating, the coating rack 11 can be prevented from shaking, thereby ensuring the normal progress of the coating work.

[0048] When components such as the two sliders 7, the transmission table 8, and the base block 9 move to the lower part of the vacuum chamber 2, under the action of strong magnetic force, the magnet 56 can make components such as the iron block 50, the rotating shaft two 46, and the convex rod 51 move downward until the two pressing blocks 52 contact the movable ring 53, and at the same time the two springs 48 are stretched. Then control the motor two 54 to work to make the rotating shaft three 55 and the magnet 56 rotate. Then under the action of magnetic force, the iron block 50, the rotating shaft two 46, the two L-shaped rods 47, the base block 9, and the components on the base block 9 can be rotated. In this way, the coating rack 11 can be rotated, so that uniform coating can be realized during coating.

[0049] After the coating is completed, control the second motor 54 to keep components such as the base block 9 in place. Then, control the electric push rod 4 to move the vacuum chamber 2 upward. Next, control the electric slide rail 6 to move components such as the transmission table 8 and the coating rack 11 into the housing 15. Then, control the fan 21 to work. Then, under the action of the hose 24, the second pipeline 23, the first pipeline 22, the U-shaped pipe 20, and multiple air outlet holes, the workpiece can be blown, so that the coated workpiece can be cooled. At the same time, control the first motor 26 to work, so that the first rotating shaft 27 and the bevel gear 28 can rotate. The rotation of the bevel gear 28 drives the bevel gear ring 29 to rotate, and the rotation of the bevel gear ring 29 drives the rotating plate 16 to rotate, so that components such as the two first reciprocating lead screws 18, the two first sliding seats 19, and the U-shaped pipe 20 can perform circular motion, and then the U-shaped pipe 20 rotates around the workpiece. Then, under the action of the two first gears 30 and the first gear ring 31, the two first reciprocating lead screws 18 will also rotate selflessly, so that the two first sliding seats 19 and the U-shaped pipe 20 will continuously move up and down. In this way, the U-shaped pipe 20 will rotate around the workpiece while moving up and down in a small range. In this way, the position of the air outlet holes can be continuously changed during cooling, so that the air can be evenly blown on the workpiece, ensuring that the workpiece is evenly and thoroughly cooled, so that the worker will not be scalded when removing the workpiece manually;

[0050] After the cooling is completed, control the first motor 26 to keep the U-shaped pipe 20 in place. Then, continue to control the electric slide rail 6 to move components such as the transmission table 8 to the right to reset. Then, the second gear 41 meshes with the toothed plate 43 again, and then the second sliding seat 38 and the push block 40 move forward. At the same time, under the action of the return of the torsion spring 36, the two rotating rods 34 and the two clamping blocks 35 are reset, so as to release the fixation of the coating rack 11. Then, the worker can remove the coating rack 11 from the base block 9, then place a new coating rack 11 and hang the workpiece, and then perform the work of coating, transmission, and cooling according to the same principle;

[0051] When components such as the base block 9 and the coating rack 11 are removed from the right side and lose magnetism, the second rotating shaft 46, the L-shaped rod 47, and the convex rod 51 will move upward under the action of the return of the spring 48, so that the convex rod 51 can be stuck on the U-shaped frame 49 again, so that when the second gear 41 meshes with the toothed plate 43, the base block 9 can be prevented from rotating due to resistance.

[0052] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.
