Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, specifically to a composite coating device. Background Technology
[0002] Vacuum coating equipment first evacuates the room air, reducing the internal pressure to an extremely low level, far below atmospheric pressure—a process known as vacuuming. In a vacuum environment, the density of gas molecules is very low, significantly reducing collisions and interactions between molecules, providing ideal conditions for the coating process. The vacuum environment effectively prevents gas molecules from contaminating and interfering with the coating material and substrate surface during the coating process, improving the quality and purity of the coating.
[0003] A search revealed a utility model patent with Chinese patent publication number CN216155949U, which discloses a vacuum coating composite coating device, relating to the field of vacuum coating equipment technology. The device includes a coating chamber, a vapor deposition source generator, a clamping assembly, and a coating assembly. The vapor deposition source generator is fixedly installed on the top of the coating chamber. The clamping assembly includes L-shaped clamping plates arranged opposite each other on both sides of the coating chamber. The L-shaped clamping plates are respectively connected to pushing components that drive them to move horizontally within the coating chamber. A drive motor is provided on the outside of the coating chamber.
[0004] The above-mentioned device supports the workpiece through an L-shaped clamping plate. However, its lower half is horizontal. Since the coating principle is that the material adheres to the surface of the workpiece by sedimentation, the part that is blocked by the horizontal state of the clamping plate will not be able to receive material adhesion and will need to be processed in a secondary manner, indicating room for improvement. Utility Model Content
[0005] The purpose of this invention is to provide a composite coating device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite coating device, comprising a coating box, wherein two fixing components are installed inside the coating box, the two fixing components are symmetrically arranged, each fixing component includes a mounting tube rotatably connected inside the coating box, and the mounting tube is horizontally arranged, a horizontally arranged clamping plate is slidably inserted inside the mounting tube, a support plate is rotatably connected inside the clamping plate, the support plate has two through holes at the same level inside, and the two through holes are respectively located on both sides of the rotating end of the support plate, the support plate and a through hole are slidably inserted with the same limiting pin.
[0007] As a further preferred embodiment of this technical solution, a connecting plate is fixedly connected to the outer wall of one side of the mounting tube, and a horizontally arranged lead screw is threaded inside the connecting plate. The lead screw is rotatably connected to the top sliding rod of the clamping plate, and a horizontally arranged limiting rod is slidably inserted inside the connecting plate. One end of the limiting rod is fixedly connected to the bottom sliding rod of the clamping plate.
[0008] While ensuring the workpiece is supported when not fixed, the obstruction of the support plate on the workpiece can also be eliminated as needed, which is beneficial to ensuring the coating effect and eliminating the need for secondary processing. The workpiece to be coated is placed on top of the two support plates. The support plate connected inside the clamping plate can only be rotated, but is restricted by the limit pin, so the support plate will remain in a horizontal state, thus supporting the workpiece. Then, the screw is driven to rotate by the handle. The screw rotates and moves along the connecting plate towards the inside of the mounting tube. The clamping plate inserted inside the mounting tube is restricted to translation. The screw can then drive the clamping plate closer to the workpiece. Repeat the operation to drive the other clamping plate to press against the side wall of the workpiece. Then, pull out the limit pin from the support plate. The support plate is no longer restricted and rotates downward. Then push the support plate to rotate to the other side. Then, the limit pin restricts the support plate again, so the workpiece will not be obstructed.
[0009] As a further preferred embodiment of this technical solution, the bottom of the coating box is rotatably connected to a horizontally arranged transmission rod via a mounting bracket. Two sprockets are coaxially fixed to the outside of the transmission rod, and two sprockets are also coaxially fixed to the outside of the two clamping plates. The two sprockets on one side are fitted with the same chain. A motor is fixedly mounted to the outside of one of the mounting brackets of the transmission rod, and the output end of the motor is coaxially fixed to one end of the transmission rod.
[0010] As a further preferred embodiment of this technical solution, two vapor deposition source generators are fixedly installed on the top outer wall of the coating box, and the same conveying pipe is installed at the outlet of both vapor deposition source generators, with a discharge assembly installed at the outlet end of the conveying pipe.
[0011] As a further preferred embodiment of this technical solution, the discharge assembly includes a discharge pipe fixedly connected to the bottom of the discharge port of the conveying pipe. The discharge pipe is connected to the conveying pipe. Two symmetrically arranged piston rods are slidably inserted inside the discharge pipe. Two extension plates are fixedly connected to the outer wall of one end of the discharge pipe. The two piston rods are slidably inserted into the two extension plates respectively. A positioning screw is threaded into the interior of each of the two extension plates. Several limiting holes adapted to the positioning screws are opened on the outer wall of one end of each of the two piston rods.
[0012] For coating workpieces of other lengths, rotate the positioning screw to disengage it from the limiting hole outside the piston rod. The piston rod will then be no longer restricted. Next, adjust the piston end of the piston rod to be in the position of the discharge pipe. Under the restriction of the piston rod, steam can only flow to the outside through the nozzle in the middle of the two piston rods. Finally, rotate the positioning screw to enter a limiting hole again along the extension plate, which helps to improve the adaptability of the device.
[0013] As a further preferred embodiment of this technical solution, the outer wall of the top of the coating box is provided with a connection port.
[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread groove of the lead screw is smaller than the equivalent friction angle.
[0015] This utility model provides a composite coating device, which has the following beneficial effects:
[0016] (1) By setting a fixing component, this utility model can ensure that the workpiece can be supported when it is not fixed, and can also eliminate the obstruction of the workpiece by the support plate as needed, which is conducive to ensuring the coating effect and saving the secondary processing steps. The workpiece to be coated is placed on the top of the two support plates. The support plate connected inside the clamping plate can only be rotated and is restricted by the limit pin. The support plate will remain in a horizontal state, which can achieve the effect of supporting the workpiece. Then, the screw is driven to rotate by the handle. The screw rotates and moves along the connecting plate towards the inside of the mounting tube. The clamping plate inserted inside the mounting tube is restricted to only move horizontally. The screw can drive the clamping plate to approach the workpiece. Repeat the operation to drive the other clamping plate to press the side wall of the workpiece. Then, pull out the limit pin from the support plate. The support plate is no longer restricted and flips downward. Then push the support plate to flip to the other side. Then, the support plate is restricted again by the limit pin, so that the workpiece will not be blocked.
[0017] (2) By setting up a discharge assembly, such as for coating of workpieces of other lengths, the rotating positioning screw is made to disengage from the limiting hole outside the piston rod, and the piston rod will no longer be restricted. Then, the piston end of the piston rod is adjusted to be in the discharge pipe. Under the restriction of the piston rod, the steam can only flow to the outside through the nozzle in the middle of the two piston rods. Finally, the rotating positioning screw enters a limiting hole again along the extension plate, which is beneficial to improving the adaptability of the device. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figure 2 As shown in Figure 4, in this embodiment, a composite coating device includes a coating box 1. Two fixing components 5 are installed inside the coating box 1. The two fixing components 5 are arranged symmetrically. Each fixing component 5 includes a mounting tube 501 rotatably connected inside the coating box 1. The mounting tube 501 is horizontally arranged. A horizontally arranged clamping plate 505 is slidably inserted inside the mounting tube 501. A support plate 506 is rotatably connected inside the clamping plate 505. The support plate 506 has two through holes at the same level inside. The two through holes are located on both sides of the rotating end of the support plate 506. The same limiting pin 507 is slidably inserted into the support plate 506 and one through hole.
[0025] A connecting plate 502 is fixedly connected to the outer wall of one side of the mounting tube 501. A horizontally arranged lead screw 503 is threaded inside the connecting plate 502. The lead screw 503 is rotatably connected to the top sliding rod of the clamping plate 505. A horizontally arranged limiting rod 504 is slidably inserted inside the connecting plate 502. One end of the limiting rod 504 is fixedly connected to the bottom sliding rod of the clamping plate 505.
[0026] The workpiece to be coated is placed on top of the two support plates 506. The support plate 506, which is rotatably connected inside the clamping plate 505, can only rotate, but is restricted by the limiting pin 507, so the support plate 506 will remain in a horizontal state, thus supporting the workpiece. Then, the screw 503 is rotated by the handle. The screw 503 rotates and moves along the connecting plate 502 towards the inside of the mounting tube 501. The clamping plate 505, which is inserted inside the mounting tube 501, is restricted to translation. The screw 503 can drive the clamping plate 505 closer to the workpiece. The operation is repeated to drive the other clamping plate 505 to press against the side wall of the workpiece. Then, the limiting pin 507 is pulled out of the support plate 506, and the support plate 506 is no longer restricted to rotate downward. Then, the support plate 506 is pushed to rotate to the other side. Then, the limiting pin 507 restricts the support plate 506 again, so the workpiece will not be obstructed.
[0027] like Figure 4 As shown, the bottom of the coating box 1 is rotatably connected to a horizontally arranged transmission rod 508 via a mounting bracket. Two sprockets 509 are coaxially fixed to the outside of the transmission rod 508, and two clamping plates 505 are also coaxially fixed to the outside of each other. The two sprockets 509 on one side are fitted with the same chain. A motor 510 is fixedly mounted on the outside of one of the mounting brackets of the transmission rod 508. The output end of the motor 510 is coaxially fixed to one end of the transmission rod 508.
[0028] The starting motor 510 drives the transmission rod 508 to rotate, which in turn drives the two sprockets 509 connected to it to rotate. The sprockets 509 drive the mounting tube 501 to rotate via the chain and the external sprocket 509 of the mounting tube 501. The two clamping plates 505 can then drive the workpiece to rotate. Combined with the steam sprayed from the discharge pipe 601, the workpiece can be fully coated.
[0029] like Figure 1 As shown in Figure 2, two vapor deposition source generators 2 are fixedly installed on the top outer wall of the coating box 1. The preferred model is a low temperature beam source furnace (NTEZ). The same conveying pipe 3 is installed at the outlet of both vapor deposition source generators 2, and a discharge assembly 6 is installed at the outlet end of the conveying pipe 3.
[0030] After completing one layer of coating, one of the vapor deposition generators 2 is turned off, and the other vapor deposition generator 2 is started. The steam generated by the generator is used to deposit another layer of coating on the workpiece through the conveying pipe 3 and the discharge pipe 601.
[0031] like Figure 2 and Figure 3As shown, the discharge assembly 6 includes a discharge pipe 601 fixedly connected to the bottom of the discharge port of the conveying pipe 3. The discharge pipe 601 is connected to the conveying pipe 3. Two symmetrically arranged piston rods 603 are slidably inserted inside the discharge pipe 601. Two extension plates 602 are fixedly connected to the outer wall of one end of the discharge pipe 601. The two piston rods 603 are slidably inserted into the two extension plates 602 respectively. A positioning screw 604 is threaded inside each of the two extension plates 602. Several limiting holes 605 adapted to the positioning screw 604 are opened on the outer wall of one end of each of the two piston rods 603.
[0032] For coating workpieces of other lengths, rotate the positioning screw 604 to disengage it from the limiting hole 605 outside the piston rod 603. The piston rod 603 will no longer be restricted. Then, adjust the piston end of the piston rod 603 to be in the position of the discharge pipe 601. Under the restriction of the piston rod 603, the steam can only flow to the outside through the nozzle in the middle position of the two piston rods 603. Finally, rotate the positioning screw 604 to enter a limiting hole 605 again along the extension plate 602, which helps to improve the adaptability of the device.
[0033] like Figure 1 As shown, the top outer wall of the coating chamber 1 is provided with a connection port, which allows the coating chamber 1 to be connected to an external vacuuming device.
[0034] like Figure 1 As shown in Figure 2, the thread helix angle of the external thread groove of the lead screw 503 is smaller than the equivalent friction angle, which gives it self-locking properties and prevents it from changing position arbitrarily when subjected to force.
[0035] This utility model provides a composite coating device, the specific working principle of which is as follows:
[0036] When the device is working, the workpiece to be coated is placed on top of the two support plates 506. The support plate 506, which is rotatably connected to the clamping plate 505, can only rotate, but is restricted by the limit pin 507, so the support plate 506 will remain in a horizontal state, thus supporting the workpiece. Then, the screw 503 is rotated by the handle. The screw 503 rotates and moves along the connecting plate 502 towards the mounting tube 501. The clamping plate 505, which is inserted into the mounting tube 501, is restricted to translation. The screw 503 can then drive the clamping plate 505 closer to the workpiece. The operation is repeated to drive the other clamping plate 505 to press against the side wall of the workpiece. Then, the limit pin 507 is pulled out of the support plate 506, and the support plate 506 is no longer restricted to rotate downward. Then, the support plate 506 is pushed to rotate to the other side. Then, the limit pin 507 restricts the support plate 506 again, so the workpiece is not obstructed. The motor 510 is started to drive the transmission rod 508 to rotate, and the transmission rod 508 drives the... The two connected sprockets 509 rotate, and the sprockets 509 drive the mounting tube 501 to rotate through the chain and the external sprocket 509 of the mounting tube 501. The two clamping plates 505 can drive the workpiece to rotate. With the steam sprayed from the discharge pipe 601, the workpiece can be fully coated. After one layer of coating is completed, one of the vapor deposition source generators 2 is turned off and the other vapor deposition source generator 2 is turned on. The steam generated by it is used to coat the workpiece with another layer of coating through the conveying pipe 3 and the discharge pipe 601. If coating workpieces of other lengths, the positioning screw 604 is rotated to disengage it from the limiting hole 605 outside the piston rod 603. The piston rod 603 will no longer be restricted. Then, the piston end of the piston rod 603 is adjusted to be in the position of the discharge pipe 601. Under the restriction of the piston rod 603, the steam can only flow to the outside through the nozzle in the middle of the two piston rods 603. Finally, the positioning screw 604 is rotated to enter a limiting hole 605 again along the extension plate 602, which helps to improve the adaptability of the device.
