Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum coating, more particularly to a rotating frame device for vacuum coating. BACKGROUND

[0002] Vacuum coating is a method of putting the workpiece to be coated into a high vacuum cavity, using heating, arc or ion beam to make the target material gasify, and then the atoms are directly deposited on the surface of the coating part to form a dense and high-purity film. In order to improve the uniformity of the coating and reduce the dead angle of the coating, the coating part needs to be placed on a rotating frame, and the coating part is continuously rotated by the rotating frame while the vacuum coating is being carried out.

[0003] When vacuum coating the coating part, the coating part needs to be kept in a rotating state. When facing an excessively heavy coating part, the worker needs to adjust and control the rotation speed of the coating part and the rotating frame. When the worker makes a mistake or forgets to adjust the rotation speed of the rotating frame, the coating part will be thrown due to the excessive rotation speed, and multiple coating parts will be stacked and crowded together, or even be thrown out, resulting in the blocking of the coating part during the coating process, affecting the coating quality of the coating part, and the thrown-out coating part will be damaged and cannot be normally coated, and even the vacuum coating equipment will be damaged by collision.

[0008] Further, the rolling shaft is made of elastic rubber material.

[0009] Further, the anti-disengagement mechanism is arranged below the top plate, the anti-disengagement mechanism comprises a plurality of partition plates fixedly sleeved on the surface of the middle support column, the outer arc surface of the partition plates is sleeved with an external frame, a plurality of passive guide rods are inserted into the internal part of the external frame, a driving screw is threadedly inserted into the internal part of the uppermost external frame, the bottom end of the driving screw is rotationally connected with an active guide rod, the surface of the active guide rod and the surface of the plurality of passive guide rods are fixedly connected with a lifting track, an upper bracket is slidingly inserted into the internal part of the lifting track, the cross section shape of the upper bracket is L-shaped, and the top end of the longitudinal arm end of the upper bracket is fixedly connected with a limiting frame.

[0010] Further, the end of the transverse arm end of the upper bracket away from the limiting frame is fixedly connected with a stop block, and the end of the plurality of lifting tracks close to each other is fixedly connected with a stop frame.

[0011] Further, the dialing mechanism is arranged on the surface of the middle support column, the middle support column comprises a plurality of inner rings fixedly sleeved on the surface of the middle support column, the surface of the inner ring is rotationally sleeved with an outer ring, and the outer arc surface of the outer ring is fixedly connected with a plurality of dialing slats.

[0012] Further, the dialing slats are made of lead material.

[0013] Further, the second rolling rod is rotationally connected with the inner part of the upper surface of the dialing slat.

[0019] (3) The driving batten is made of lead, which is relatively heavy, and the inertia tends to maintain the original state, so the momentum change is small, and the friction force impulse generated by the driving batten is small. Therefore, when the rotation speed difference between the suspension rod and the driving batten is large, the coated part keeps contacting the second rolling rod made of rubber material when the suspension rod drives the coated part to rotate, so that the coated part is lifted and deviated, the blocked part of the coated part is exposed, and the dead angle of the coated part is reduced.

[0020] (4) The distance between the suspension rod and the driving batten can be adjusted by rotating the threaded rotating sleeve, so that the position of the lower end of the coated part that can be lifted by the driving batten can adapt to coated parts of various sizes, and the application range of the rotating frame is improved.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] Please refer to Figures 1-3 A rotating frame device for vacuum coating, comprising a top plate 1, a bottom plate 2 and a middle support 3, the middle support 3 is fixedly connected with the middle part of the upper surface of the bottom plate 2, the upper end of the middle support 3 is fixedly connected with the middle part of the top plate 1, an emergency stop mechanism, the emergency stop mechanism is arranged below the top plate 1, the emergency stop mechanism comprises two guide rails 402 fixedly connected with the upper end of the middle support 3, a counterweight sliding block 404 is slidably connected inside the guide rail 402, a brake block 406 is fixedly connected with the upper surface of the counterweight sliding block 404, two brake grooves 403 are formed in the lower surface of the top plate 1, a rolling shaft 407 is inserted into the brake groove 403 after shape recovery, so that the suspension rod 401 cannot continue to rotate, a plurality of groups of suspension rods 401 are arranged on the surface of the middle support 3, the number of each group of suspension rods 401 is multiple, the top end of the brake block 406 is rotatably connected with the rolling shaft 407, and the two brake grooves 403 are respectively matched with the two rolling shafts 407.

[0034] The inside of the guide rail 402 is fixedly connected with a resistance spring 405, the resistance spring 405 can slowly pull the rolling shaft 407 out of the brake groove 403 when the speed is restored to normal, one end of each of the two resistance springs 405 away from each other is fixedly connected with one end of the two counterweight sliding blocks 404 close to each other, the counterweight sliding block 404 is made of lead material, which can provide stronger centrifugal force, and the rolling shaft 407 is made of elastic rubber material, which can deform the rolling shaft 407.

[0035] By adopting the above technical scheme, when the coating part is vacuum coated, the rotating frame is installed in the inside of the vacuum coating equipment, then the coating part is hung on the suspension rod 401, and the gasified target material is sprayed from the side of the vacuum coating equipment to coat the coating part. During the coating process, the middle support 3 is driven to rotate by the motor in the inside of the vacuum coating equipment, thereby driving the suspension rod 401 to rotate, improving the uniformity of coating and reducing the dead angle of coating.

[0036] When the middle pillar 3 rotates, the guide rail 402 will rotate synchronously. When the rotation speed of the suspension rod 401 is too fast, the centrifugal force generated will cause the two counterweight sliders 404 to move away from each other. Since the rolling shaft 407 is in close contact with the lower surface of the top plate 1, the rolling shaft 407 is subjected to extrusion deformation. Therefore, when the counterweight slider 404 is moved below the brake groove 403 by the centrifugal force, the rolling shaft 407 is inserted into the brake groove 403 after deformation recovery. If the rotation degree is low, the suspension rod 401 will be directly clamped in the brake groove 403, so that the suspension rod 401 cannot continue to rotate. If the rotation degree is high, the suspension rod 401 will pass through the brake groove 403, but can slow down and produce noise to remind the staff to find and control in time, so as to prevent the coating parts from rotating too fast and being stacked together.

[0037] As shown in Figure 4 and Figure 5 , the anti-disengagement mechanism is arranged below the top plate 1, and the anti-disengagement mechanism comprises a plurality of partition plates 510 fixedly sleeved on the surface of the middle pillar 3. The outer circular arc surface of the partition plate 510 is sleeved with an external frame 504, and a plurality of passive guide rods 502 are inserted into the internal part of the external frame 504. The internal part of the uppermost external frame 504 is threadedly inserted with a driving screw 503. The driving screw 503 can drive the synchronous downward movement of the active guide rod 501 and the plurality of passive guide rods 502. The bottom end of the driving screw 503 is rotationally connected with the active guide rod 501. The surface of the active guide rod 501 and the surface of the plurality of passive guide rods 502 are both fixedly connected with a lifting rail 505. The internal part of the lifting rail 505 is slidably inserted with an upper bracket 506. The cross-sectional shape of the upper bracket 506 is “L” shape. The top end of the longitudinal arm end of the upper bracket 506 is fixedly connected with a limiting frame 509. The suspension rod 401 is clamped in the internal part of the limiting frame 509. The coating parts cannot be disengaged and thrown out by the blocking of the active guide rod 501 and the plurality of passive guide rods 502, thereby improving the safety during the coating process. The transverse arm end of the upper bracket 506 is fixedly connected with a stop block 507 away from the limiting frame 509. One end of the lifting rail 505 close to the other lifting rail 505 is fixedly connected with a blocking frame 508. The cooperation of the stop block 507 and the blocking frame 508 can prevent the upper bracket 506 from disengaging from the lifting rail 505.

[0038] By adopting the above technical scheme, when facing some relatively heavy coated parts, even if the rotating speed is relatively slow, the coated parts are still easy to be thrown out, and the throwing out of the relatively heavy coated parts is more likely to cause damage to the vacuum coating equipment, so after the coated part is hung on the suspension rod 401, the driving screw 503 is rotated, which can drive the driving guide rod 501 and the plurality of passive guide rods 502 to move downward synchronously, so that the height of the corresponding limiting frame 509 is lower than the height of the corresponding suspension rod 401, then the plurality of upper brackets 506 are moved towards each other, the plurality of upper brackets 506 are moved to the position directly below the suspension rod 401, then the driving screw 503 drives the driving guide rod 501 and the plurality of passive guide rods 502 to move upward, so that the suspension rod 401 is clamped in the inside of the limiting frame 509, and the coated part cannot be separated from the throwing out by the blocking of the driving guide rod 501 and the plurality of passive guide rods 502, thereby improving the safety during the coating process.

[0039] As shown in Figure 6 The dialing mechanism is arranged on the surface of the middle support column 3, the middle support column 3 includes a plurality of inner rings 607 fixedly sleeved on the surface of the middle support column 3, the surface of the inner ring 607 is rotatably sleeved with an outer ring 606, the outer arc surface of the outer ring 606 is fixedly connected with a plurality of dialing slats 601, the dialing slats 601 are made of lead material and are relatively heavy, and due to inertia, the momentum change is small, and the friction impulse generated on the dialing slats 601 is small, so when the rotating speed difference between the suspension rod 401 and the dialing slat 601 is large, the inner surface of the upper surface of the dialing slat 601 is rotatably connected with a second rolling rod 603, and the inner surface of the upper surface of the suspension rod 401 is rotatably connected with a first rolling rod 602, and the first rolling rod 602 and the second rolling rod 603 can reduce the abrasion caused to the coated part.

[0040] The surface of the middle support column 3 is provided with a plurality of threaded grooves 605, the surface of the middle support column 3 is sleeved with a plurality of threaded rotating sleeves 604, the plurality of threaded rotating sleeves 604 are respectively threadedly connected with the middle support column 3 through the plurality of threaded grooves 605, and the plurality of suspension rods 401 are fixedly connected with the outer arc surface of the threaded rotating sleeve 604, so that the distance between the suspension rod 401 and the dialing slat 601 can be adjusted, and the position at which the lower end of the coated part can be lifted by the dialing slat 601 can be adapted to the coated parts of various sizes.

[0041] By adopting the above technical scheme, the plurality of suspension rods 401 are driven to rotate synchronously when the middle support 3 rotates, thereby driving the coated member to rotate. Since the poking slats 601 are made of lead and are heavy as a whole, inertia tends to keep the original state, momentum changes little, and the friction impulse generated on the poking slats 601 is small. Therefore, when the rotation speed difference between the suspension rods 401 and the poking slats 601 is large, the coated member is in constant contact with the second rolling rod 603 made of rubber when the suspension rods 401 drive the coated member to rotate, so that the coated member is lifted and deviated, the part of the coated member that is shielded is exposed, and the dead angle of the coated member is reduced. By rotating the threaded rotating sleeve 604, the distance between the suspension rods 401 and the poking slats 601 can be adjusted, and the position at which the lower end of the coated member can be lifted by the poking slats 601 can be adapted to the coated member of various sizes.

[0042] Method for use: first, install the rotating frame in the interior of the vacuum coating device;

[0043] Next, hang the coated member on the suspension rods 401;

[0044] Then, drive the screw rod 503 to rotate, drive the driving guide rod 501 and the plurality of passive guide rods 502 to move downward, so that the height of the corresponding limiting frame 509 is lower than the height of the corresponding suspension rod 401;

[0045] Then, the plurality of upper brackets 506 move towards each other, and the plurality of upper brackets 506 move to the position directly below the suspension rods 401;

[0046] Next, drive the screw rod 503 to drive the driving guide rod 501 and the plurality of passive guide rods 502 to move upward, so that the suspension rods 401 are clamped in the interior of the limiting frame 509;

[0047] Next, rotate the threaded rotating sleeve 604 to adjust the distance between the suspension rods 401 and the poking slats 601, so that the position at which the lower end of the coated member can be lifted by the poking slats 601;

[0048] Next, drive the middle support 3 to rotate by the motor in the interior of the vacuum coating device

[0049] Finally, the gasified target material is sprayed from the side of the vacuum coating device to perform coating treatment on the coated member.

[0050] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical range disclosed in the present application according to the technical solution and improvement concept of the present application, which should be covered in the protection scope of the present application.
