The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See also Figures 1 to 6As shown, it is a hanging device of a vacuum coating equipment in one embodiment of the utility model. In some preferred embodiments, the vacuum coating equipment includes four supporting legs 3, the upper ends of the four supporting legs 3 are commonly fixedly connected to the coating chamber structure 2, the middle of the left end of the coating chamber structure 2 is fixedly connected to the switch device 1, the four supporting legs 3 play a role in supporting the entire coating chamber structure 2, and the right front side of the coating chamber structure 2 is rotatably connected to a rotating sealing door 4.

[0037] Specifically, the hanging device 5 includes a rotating shaft 551 arranged in the coating chamber structure 2 and a hanging rack 552 connected to the rotating shaft 551, the hanging rack 552 has the function of hanging the hanger, supporting the hanging rack 552 through the rotating shaft 551, and driving the hanging rack 552 to rotate. In some other preferred embodiments, the vacuum coating equipment also includes a driving member 6, and the switch device 1 is electrically connected to the driving member 6, wherein the output end of the driving member 6 is connected to one end of the rotating shaft 551 for driving the rotating shaft 551 to rotate.

[0038] It should be noted that the specific installation method of the switch device 1 and the drive member 6, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means for those skilled in the art. The coating chamber structure 2 includes devices such as a vapor deposition source and a conductive heating device, and the switch device 1 includes devices such as a sensor and a control module. They only need to meet the purpose of performing vacuum coating and improving the uniformity of the coating, and no special explanation is given here.

[0039] Specifically, the driving member 6 may be a driving motor.

[0040] In order to facilitate the coating treatment of the hanging part, the hanging device 5 in this embodiment further includes at least one slide bar 541 and an anti-drop frame 542 connected to the slide bar 541;

[0041] The slide bar 541 is slidably connected to the rotating shaft 551, and the sliding direction of the slide bar 541 extends along the radial direction of the rotating shaft 551, so that when the slide bar 541 slides back and forth on the rotating shaft 551, the slide bar 541 drives the anti-slip frame 542 to move away from or fit together with the hanging frame 552 as the target;

[0042] The hanging frame 552 and the anti-slip frame 542 are both bent inward, and the bending directions of the hanging frame 552 and the anti-slip frame 542 are relatively arranged, so that when the hanging frame 552 and the anti-slip frame 542 are in contact with each other, one end of the hanging frame 552 and one end of the anti-slip frame 542 are connected to each other to form a hanging space for the hanging movement.

[0043] That is to say, when the hanger is coated, the slide bar 541 is used to slide along the radial direction of the rotating shaft 551, so that the slide bar 541 drives the anti-slip frame 542 to move away from or fit together with the hanger frame 552 as the target. When the anti-slip frame 542 and the hanger frame 552 fit together, the open hanger frame 552 is converted into a closed type, so that the movement of the hanger is restricted, and the stability and reliability of the hanger hanging on the hanger frame 552 are guaranteed. Moreover, since the hanger frame 552 and the anti-slip frame 542 are both bent inwardly, the bending directions of the hanger frame 552 and the anti-slip frame 542 are relatively arranged, so that when the hanger frame 552 and the anti-slip frame 542 fit together, one end of the hanger frame 552 and one end of the anti-slip frame 542 are connected to each other to form a hanging space for the hanger to move, thereby ensuring that the hanger has sufficient space to move on the hanger frame 552, so as to improve the practicality of the vacuum coating equipment provided by the utility model.

[0044] See also Figure 4 and Figure 5 As shown, in some preferred embodiments, there can be two slide bars 541, and two slide rails 554 for the slide bars 541 to slide are arranged on the rotating shaft 551. The outer surfaces of the two slide bars 541 on the same side are slidably connected with the inner cavities of the two slide rails 554 on the same side. It should be noted that the use of the slide rail 554 is one of the sliding connection methods, and other combinations of sliding connections can also be used, which are not specifically explained here.

[0045] Furthermore, in order to limit the sliding of the slide bar 541 relative to the rotating shaft 551, the hanging device 5 further includes a fixing card group 543 arranged on the slide bar 541;

[0046] A clamping member 553 matched with the fixed clamping group 543 is disposed on the rotating shaft 551 . The clamping member 553 is used to clamp the fixed clamping group 543 to limit the sliding of the slide bar 541 relative to the rotating shaft 551 .

[0047] That is to say, in some preferred embodiments, when the hanging rack 552 and the anti-slip rack 542 fit together, the fixing card group 543 is clamped by the clamping piece 553, so that the sliding bar 541 is relatively fixed, that is, the hanging rack 552 and the anti-slip rack 542 are just pressed against each other and connected, so as to improve the stability of the hanging rack 552 and the anti-slip rack 542 after being connected by the fixing card group 543.

[0048] In some other preferred embodiments, when the hanger is coated and needs to be removed from the hanger rack 552, the hanger rack 552 and the anti-drop frame 542 are moved away from each other, that is, in some actual situations, the slide bar 541 moves upward, and after the slide bar 541 moves upward for a certain distance, the clamping member 553 is used to clamp the fixed card group 543, so that the slide bar 541 is relatively fixed, and the hangers can be removed one by one.

[0049] It should be noted that whether it is to improve the stability of the hanger frame 552 and the anti-slip frame 542 after being connected, or to facilitate the removal of the hanger, it can be achieved by adjusting the position of the clamping member 553 on the rotating shaft 551. When the clamping member 553 is set in a state that is convenient for removing the hanger, a concave-convex structure can be set at the end where the hanger frame 552 and the anti-slip frame 542 are close to each other to ensure the stability of the two after the connection.

[0050] See also Figure 6 As shown, specifically, the fixed card group 543 includes an inner ring 5431 and an outer ring 5434 rotatably connected to each other, and the inner ring 5431 and the outer ring 5434 are respectively provided with a first card slot 5432 and a second card slot 5433 that match the card connector 553, and the first card slot 5432 and the second card slot 5433 are connected to each other;

[0051] The first slot 5432 extends radially along the inner ring 5431 , and the second slot 5433 extends axially along the outer ring 5434 , so that when the clamping member 553 passes through the first slot 5432 and enters the second slot 5433 , the outer ring 5434 is rotated to clamp the clamping member 553 .

[0052] Specifically, the inner ring 5431 is connected to the slide bar 541 .

[0053] In some other preferred embodiments, the slide bar 541 and the anti-slip frame 542 are fixedly connected, the rotating shaft 551 and the hanging frame 552 are fixedly connected, and in order to ensure the mutual rotational connection between the inner ring 5431 and the outer ring 5434, a rotation groove 5435 is opened on the outer surface of the inner ring 5431, and the outer ring 5434 is rotationally connected to the inner ring 5431 through the rotation groove 5435.

[0054] When the parts are hung on each hanger rack 552 in turn, the inner ring 5431 is slid first, so that the inner ring 5431 drives the slide bar 541 and the anti-slip frame 542 to slide on the inner cavity of the slide rail 554 and the outer surface of the rotating shaft 551 respectively. At the same time, the lower part of the outer surface of the anti-slip frame 542 is separated from the upper part of the outer surface of the hanger rack 552, so that the parts that need vacuum coating are hung on the hanger rack 552 in turn. The parts hung on the hanger rack 552 are restricted by the fixed card group 543 and the self-gravity of the slide bar 541, so as to prevent the parts from accidentally falling during the vacuum coating process.

[0055] In order to facilitate the removal of parts after coating, after coating is completed, the inner ring 5431 is slid upwards, so that the inner ring 5431 drives the outer ring 5434 in the inner cavity of the rotating groove 5435 to slide upwards, and at the same time drives the sliding bar 541 and the anti-stripping frame 542 to slide upwards, so that the clamping member 553 slides through the first clamping groove 5432 and reaches the inner cavity of the second clamping groove 5433, and then the outer ring 5434 is rotated to make the second clamping groove 5433 slide on the outer surface of the clamping member 553 respectively, so that the outlet of the second clamping groove 5433 is staggered with the first clamping groove 5432, and then the inner ring 5431 drives the sliding bar 541 and the anti-stripping frame 542 to be fixed, and the anti-stripping frame 542 is restricted from sliding up and down, so that the coated parts are taken out from the hanging frame 552, thereby achieving the purpose of facilitating the removal of parts after coating.

[0056] Furthermore, at least two first slots 5432 are provided, and at least two first slots 5432 are symmetrically arranged on the inner wall of the inner ring 5431, and at least two clamping members 553 are provided on the rotating shaft 551, and at least two clamping members 553 are symmetrically arranged on the rotating shaft 551; wherein each clamping member 553 is arranged opposite to each first slot 5432.

[0057] In addition, in order to improve the practicality of the hanging device 5 of the vacuum coating equipment provided by the utility model, the vacuum coating equipment further includes a transmission mechanism 56;

[0058] The vacuum coating equipment includes a plurality of rotating shafts 551, and the plurality of rotating shafts 551 are arranged at intervals in the coating chamber structure 2. The plurality of rotating shafts 551 are connected to each other through a transmission mechanism 56, so that when the driving member 6 drives any rotating shaft 551 to rotate, the other rotating shafts 551 rotate synchronously.

[0059] Furthermore, a plurality of hanger racks 552 are provided on the rotating shaft 551, and the plurality of hanger racks 552 are arranged at intervals along the radial direction of the rotating shaft 551;

[0060] A plurality of anti-slip frames 542 are disposed on the slide bar 541 , and the plurality of anti-slip frames 542 are arranged at intervals along the radial direction of the slide bar 541 , and each hanging frame 552 is arranged opposite to each anti-slip frame 542 .

[0061] Specifically, there may be six rotating shafts 551 , and four hanging racks 552 may be disposed on each rotating shaft 551 , and four anti-slip racks 542 may be disposed on each sliding bar 541 .

[0062] To facilitate understanding of the operating principle of the transmission mechanism 56 in this case, the rotating shaft 551, the hanging frame 552, the clamping member 553 and the slide rail 554 are collectively referred to as the suspension group 55; the slide bar 541, the anti-drop frame 542, and the fixed card group 543 are collectively referred to as the anti-drop mechanism 54.

[0063] In some preferred embodiments, in order to facilitate driving each hanging frame 552 to rotate, the hanging device 5 in this example also includes a rotating disk 51, and six rotating holes 52 are opened in a circular array at the lower end of the rotating disk 51, and the inner cavities of the six rotating holes 52 are rotatably connected with a suspension group 55, and the middle parts of the six suspension groups 55 are slidably connected with an anti-drop mechanism 54, and a through hole is opened in the middle part of the upper end of the rotating disk 51, and the inner cavity of the through hole is rotatably connected with a shaft rod 53, and the lower part of the six suspension groups 55 and the lower part of the outer surface of the shaft rod 53 are slidably connected with a transmission mechanism 56, the upper end of the shaft rod 53 is fixedly connected to the output end of the driving member 6, the upper end of the rotating disk 51 is fixedly connected to the top wall of the inner cavity of the coating chamber structure 2, and the lower part of the transmission mechanism 56 is fixedly connected to the bottom wall of the inner cavity of the coating chamber structure 2.

[0064] It should be noted that, in order to facilitate driving, the driving member 6 and the shaft rod 53 are connected.

[0065] In order to achieve the purpose of rotating the suspension group 55, as Figure 3 As shown, the transmission mechanism 56 includes a hollow fixed disk 561, and a toothed disk 2 564 is rotatably connected to the middle part of the inner cavity of the hollow fixed disk 561. The upper end of the toothed disk 2 564 in the vertical direction penetrates the middle part of the top wall of the inner cavity of the hollow fixed disk 561 and is provided with a square groove 2 565. The inner cavity of the hollow fixed disk 561 is rotatably connected with six toothed disks 1 562 in a circular array. The upper ends of the six toothed disks 1 562 in the vertical direction all penetrate the top wall of the inner cavity of the hollow fixed disk 561 and are provided with a square groove 1 563. The sides of the middle parts of the outer surfaces of the six square grooves 1 563 that are close to each other are meshed and connected with the middle part of the outer surface of the toothed disk 2 564. The inner cavity of the square groove 2 565 is slidably connected to the lower part of the outer surface of the shaft 53, so as to drive the square groove 2 565 to rotate through the shaft 53.

[0066] First, start the driving member 6 to drive the shaft 53 to rotate, and drive the gear plate 2 564 to rotate in the inner cavity of the hollow fixed disk 561 with the cooperation of the square groove 2 565. The rotation of the gear plate 2 564 drives the six gear plates 1 562 to rotate in the inner cavity of the hollow fixed disk 561 at the same time, and then cooperates with the square groove 1 563 to drive the six suspension groups 55 to rotate at the same time.

Moreover, since the hanging frame 552 and the anti-slip frame 542 are both bent inwardly, the bending directions of the hanging frame 552 and the anti-slip frame 542 are relatively arranged, so that when the hanging frame 552 and the anti-slip frame 542 fit together, one end of the hanging frame 552 and one end of the anti-slip frame 542 are connected to each other to form a hanging space for the hanger to move, thereby ensuring that the hanger has sufficient space to move on the hanging frame 552, so as to improve the practicality of the vacuum coating equipment provided by the utility model.
