Description

Technical Field

[0001] The utility model relates to the technical field of PVD vacuum coating, and particularly relates to a double-hook hanging plate applied to PVD vacuum coating. Background Technique

[0002] Vacuum coating is based on vacuum technology, uses physical or chemical methods, and absorbs a series of new technologies such as electron beam, molecular beam, ion beam, plasma beam, radio frequency, and magnetron, providing a new process for thin film preparation for scientific research and actual production. Simply put, the method of evaporating or sputtering metals, alloys, or compounds in a vacuum and solidifying and depositing them on the object to be coated is called vacuum coating.

[0003] Currently, when an object is vacuum-coated, the traditional method is to hang and fix the object and then coat it. During the coating process, the object is in a static state, resulting in coating only for a single object and low coating efficiency. Based on this, we propose an improvement on a double-hook hanging plate applied to PVD vacuum coating. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a double-hook hanging plate applied to PVD vacuum coating, which can effectively solve the technical problem that the object is in a static state during coating and the coating efficiency is low in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A double-hook hanging plate applied to PVD vacuum coating includes a support and a turntable. The upper end of the support is rotatably connected with a driving sleeve. A sliding shaft is slidably sleeved in the driving sleeve. The turntable is fixedly connected to the upper end of the sliding shaft. Both sides of the lower end face of the turntable are rotatably connected with adjusting disks. Tooth rings I are fixedly sleeved on the outer walls of the two adjusting disks. The sliding shaft is rotatably sleeved near the upper end with a driven sleeve. A tooth ring II is fixedly sleeved on the outer wall of the driven sleeve. Both tooth rings I are meshed with the tooth ring II. Chutes are opened on the lower end faces of the two adjusting disks. Sliders are slidably arranged in the two chutes. Hooks are fixedly connected to the lower end faces of the two sliders.

[0007] As a further scheme of the utility model, electric push rods are fixedly connected to one side of the two adjusting disks respectively, and the output ends of the two electric push rods are fixedly connected to the outer walls of one side of the two sliders respectively.

[0008] As a further scheme of the utility model, sliding rods are fixedly connected between the inner walls on both sides of the two chutes, and the sliders are slidably sleeved on the outer walls of the sliding rods.

[0009] As a further solution of the utility model, a plurality of limiting plates are fixedly connected to the outer wall near the middle and lower part of the sliding shaft, and the plurality of limiting plates are all sleeved on the driving sleeve in a sliding manner. A limiting ring is fixedly sleeved on the outer wall near the middle and upper part of the sliding shaft, and the limiting ring is rotatably sleeved in the driven sleeve.

[0010] As a further solution of the utility model, limiting grooves are formed on both sides of the upper end surface of the support seat. Limiting blocks are slidably sleeved in the two limiting grooves. A bidirectional lead screw is rotatably connected in the two limiting grooves. The two limiting blocks are respectively threadedly connected to the outer walls on both sides of the bidirectional lead screw. Connecting plates are hinged to the upper ends of the two limiting blocks and the outer walls on both sides of the driven sleeve.

[0011] As a further solution of the utility model, an adjusting motor is fixedly arranged on one side of the support seat, and the output end of the adjusting motor is fixedly connected to one end of the bidirectional lead screw.

[0012] As a further solution of the utility model, a driving motor is fixedly connected to one side of the upper end surface of the support seat. Straight gears are fixedly sleeved on the output shaft of the driving motor and the outer wall of the driving sleeve, and the two straight gears are meshed with each other.

[0013] The beneficial effects of the utility model are as follows:

[0014] By arranging the structures of the driving sleeve, the sliding shaft, the limiting plates, the driven sleeve, the turntable, the adjusting disc, the hook, the first toothed ring and the second toothed ring, the driving sleeve can drive the sliding shaft to rotate, and then drive the turntable to rotate, and then drive the two adjusting discs to rotate around the driven sleeve. With the meshing effect of the second toothed ring fixedly sleeved on the surface of the adjusting disc and the first toothed ring fixedly sleeved on the surface of the driven sleeve, the two adjusting discs can simultaneously generate self-rotation, so as to drive the two objects suspended on the hook to rotate and self-rotate for coating, improving the coating uniformity.

[0015] By arranging the structures of the electric push rod, the sliding rod, the slider, the limiting ring, the bidirectional lead screw, the limiting block and the connecting plate, when the bidirectional lead screw drives the two limiting blocks to move relatively, the driving sleeve can be driven to move up and down through the connecting plate, which is convenient for adjusting the height of the object. At the same time, the connecting plate can limit the driven sleeve to rotate along with the sliding shaft. When the object is taken out after coating is completed, the electric push rod can push the slider, so that the hook drives the object to move to the side position of the adjusting disc, which is convenient for taking down the coated object, and has practicability.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation manners.

[0023] As Figures 1-5 shown, a double-hook hanging plate applied to PVD vacuum coating includes a support 1 and a turntable 6. The upper end of the support 1 is rotatably connected to a driving sleeve 2. A sliding shaft 3 is slidably sleeved in the driving sleeve 2. The turntable 6 is fixedly connected to the upper end of the sliding shaft 3. Both sides of the lower end surface of the turntable 6 are rotatably connected to adjusting plates 7. First gear rings 13 are fixedly sleeved on the outer walls of the two adjusting plates 7. The sliding shaft 3 is rotatably sleeved near the upper end with a driven sleeve 5. A second gear ring 14 is fixedly sleeved on the outer wall of the driven sleeve 5. Both of the first gear rings 13 are engaged with the second gear ring 14. Chutes 8 are opened on the lower end surfaces of the two adjusting plates 7. Sliders 10 are slidably arranged in the two chutes 8. Hooks 11 are fixedly connected to the lower end surfaces of the two sliders 10.

[0024] In this embodiment, electric push rods 12 are fixedly connected to one side of the two adjusting plates 7. The output ends of the two electric push rods 12 are respectively fixedly connected to the outer walls of one side of the two sliders 10. By telescoping the electric push rods 12 to adjust the positions of the sliders 10, it is convenient to push the hooks 11 to move, facilitating the taking and placing of the workpieces to be coated.

[0025] In this embodiment, sliding rods 9 are fixedly connected between the inner walls on both sides of the two chutes 8. The sliders 10 are slidably sleeved on the outer walls of the sliding rods 9. The sliding rods 9 are used to assist in supporting the sliders 10.

[0026] In this embodiment, a plurality of limiting plates 4 are fixedly connected to the outer wall near the middle and lower part of the sliding shaft 3. The plurality of limiting plates 4 are all slidably sleeved on the driving sleeve 2, so that the sliding shaft 3 can slide relative to the driving sleeve 2, and at the same time, the driving sleeve 2 can drive the sliding shaft 3 to rotate in turn. A limiting ring 15 is fixedly sleeved on the outer wall near the middle and upper part of the sliding shaft 3. The limiting ring 15 is rotatably sleeved in the driven sleeve 5, so that the sliding shaft 3 can drive the driven sleeve 5 to move up and down, and at the same time, it can rotate relative to the driven sleeve 5.

[0027] In this embodiment, limiting grooves are provided on both sides of the upper end surface of the support 1. Limiting blocks 17 are slidably sleeved in the two limiting grooves. A bidirectional lead screw 16 is rotatably connected in the two limiting grooves. The two limiting blocks 17 are respectively threadedly connected to the outer walls on both sides of the bidirectional lead screw 16. Connecting plates 18 are hinged to the upper ends of the two limiting blocks 17 and the outer walls on both sides of the driven sleeve 5.

[0028] In this embodiment, an adjusting motor 21 is fixedly arranged on one side of the support 1. The output end of the adjusting motor 21 is fixedly connected to one end of the bidirectional lead screw 16. The bidirectional lead screw 16 is driven to rotate by the adjusting motor 21 to control the relative movement of the two limiting blocks 17.

[0029] In this embodiment, a driving motor 19 is fixedly connected to one side of the upper end surface of the support 1. Straight gears 20 are fixedly sleeved on the output shaft of the driving motor 19 and the outer wall of the driving sleeve 2. The two straight gears 20 are meshed with each other. By using the meshing effect of the two straight gears 20, the driving sleeve 2 can be driven to rotate after the driving motor 19 is started.

[0030] It should be noted that the present utility model is a double-hook hanging disc applied to PVD vacuum coating. When in use, the workpiece to be coated is hung on the hook 11, and then the adjusting motor 21 is started to drive the bidirectional lead screw 16 to rotate, thereby driving the relative movement of the two limiting blocks 17, and then driving the driven sleeve 5 to move up and down relative to the support 1 through the connecting plate 18. Then, under the action of the limiting ring 15, the sliding shaft 3 is driven to move up and down, and finally the turntable 6 is driven to move up and down, so as to drive the workpiece to be coated to be adjusted in height through the adjusting disc 7 to a suitable position. Then, by using the meshing characteristics of the two straight gears 20, the driving motor 19 is started to drive the driving sleeve 2 to rotate, thereby driving the sliding shaft 3 to rotate relative to the driven sleeve 5, then driving the turntable 6 to rotate, and then driving the two adjusting discs 7 to rotate. Then, under the meshing condition of the first gear ring 13 and the second gear ring 14, the two adjusting discs 7 rotate around the driven sleeve 5 and at the same time generate self-rotation, so as to improve the coating uniformity of the workpiece to be coated. When the coated workpiece needs to be taken out after coating, first rotate the coated workpiece to a position close to the loading and unloading port in turn, and then start the electric push rod 12 to drive the slider 10 to move under the limiting action of the sliding rod 9, thereby driving the coated workpiece to move forward further, which is convenient for the relevant personnel to take and place operations.
