Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, specifically to a vacuum coating device for metal decorative panels. Background Technology

[0002] Vacuum deposition is a technology for producing thin film materials. It involves separating the atoms of a material from a heating source within a vacuum deposition chamber and projecting them onto the surface of the object to be coated. Simply put, vacuum deposition is a method of evaporating or sputtering metals, alloys, or compounds (called the target material) in a vacuum, causing them to solidify and deposit on the object to be coated (called the substrate). Based on vacuum technology, it utilizes physical or chemical methods and incorporates a range of new technologies such as electron beams, molecular beams, ion beams, plasma beams, radio frequency, and magnetron sputtering to provide a new process for thin film preparation for scientific research and practical production.

[0003] In vacuum coating processes, evaporation coating is a common and widely used method. Evaporation coating involves heating a crucible containing the target material, causing the target material to evaporate and coat the substrate surface. During the coating process, the substrate needs to be fixed by a fixture. Traditional fixtures often only have the function of fixing metal sheets. After clamping and fixing, the angle and direction of the metal sheet cannot be freely adjusted, requiring manual flipping during the coating process. This results in poor coating effects and low flexibility. In addition, the fixtures lack a buffer structure during clamping, which can easily lead to excessive force and damage to the substrate. Based on this, this solution provides a vacuum coating device for metal decorative sheets to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a vacuum coating device for metal decorative panels is provided. This technical solution solves the problems mentioned in the background art.

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

[0006] A vacuum coating apparatus for metal decorative panels includes a coating chamber with a sealed door at its front end and an observation window at its front end. A fixed frame is fixedly connected to the upper inner wall of the coating chamber. Side plates are fixedly connected to the lower front and rear sides of the fixed frame. A drive mechanism is fixedly installed on the upper end of the front side plate. A sliding groove is formed through the middle of both the front and rear ends of the fixed frame. A pair of clamping mechanisms are slidably installed on the fixed frame through the sliding groove. A flipping mechanism is provided on the outer end of the clamping mechanism. A coating assembly is provided on the lower side of the clamping mechanism. The drive mechanism includes a bidirectional motor, which is fixedly installed on the upper end of the side plate. A threaded screw is fixedly connected to each of the two output ends of the bidirectional motor. The other end of the threaded screw is rotatably connected to the inner wall of the coating chamber. A moving block is threadedly connected to the surface of the threaded screw. A connecting block is fixedly connected to the surface of the moving block. The other end of the connecting block is fixedly connected to the clamping mechanism.

[0007] Preferably, the clamping mechanism includes a movable plate, with sliders fixedly connected to both the front and rear ends of the movable plate. The other end of the slider is slidably connected to the fixed frame through a slide groove, and the rear slider extends out of the slide groove and is fixedly connected to the connecting block. A pair of anti-collision bars are fixedly connected to the outer end of the movable plate.

[0008] Preferably, a rotating block is rotatably mounted on the inner end of the movable plate, and a turntable is fixedly connected to the other end of the rotating block. A pair of telescopic rods are symmetrically arranged on the other end of the turntable. An L-shaped clamping plate is fixedly connected to the other end of the telescopic rods. A buffer spring is sleeved on the outer side of the telescopic rods, and the two ends of the buffer spring are fixedly connected to the turntable and the L-shaped clamping plate, respectively.

[0009] Preferably, the upper end of the L-shaped clamping plate is slidably connected to both the front and rear sides with fixing rods, the upper ends of the two fixing rods are fixedly connected to the lower end of the pressure plate, and a spring is provided on the outer side of the lower fixing rod.

[0010] Preferably, the flipping mechanism includes a flipping cylinder, which is fixedly installed on the outer end of the right movable plate. A toothed plate is fixedly connected to the output end of the flipping cylinder. The upper end of the toothed plate is meshed with a gear.

[0011] Preferably, one end of the toothed plate is fixedly connected to a guide rod, and the other end of the guide rod is disposed inside the guide groove, which is located at the outer end of the right movable plate.

[0012] Compared with the prior art, the present invention proposes a vacuum coating device for metal decorative panels, which has the following beneficial effects:

[0013] 1. This utility model includes a driving mechanism and a clamping mechanism. When the driving mechanism is activated, the bidirectional motor drives the threaded screws on both sides to rotate. The rotation of the threaded screws drives the moving block to move, and the moving block drives the moving plate to move through the connecting block. This enables the two clamping mechanisms to move towards or away from each other, thereby clamping or releasing the substrate. The clamping mechanism, through the cooperation of the telescopic rod and the buffer spring, allows the L-shaped clamping plate to apply pressure evenly during the clamping process, preventing the plate from deforming or warping due to excessive or uneven clamping force, thus ensuring the effect of subsequent coating. At the same time, the pressure plate can be used to clamp the metal plate in multiple directions, ensuring the stability of the clamping.

[0014] 2. This utility model includes a clamping mechanism and a flipping mechanism. After the clamping mechanism clamps the metal sheet, the clamped metal sheet is coated by the coating component. After the coating process is completed, the flipping mechanism is activated. The flipping cylinder drives the toothed plate to move, which in turn drives the gear to rotate. The gear rotation then drives the rotating block to rotate through the transmission rod. The flipping mechanisms on both sides cause the two rotating blocks to rotate in the same direction, which in turn drives the turntable to rotate. The angle and direction of the metal sheet can be freely adjusted to flip the metal sheet, making it easier to process the other side and improving the practicality and flexibility of the device.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-4 As shown, the vacuum coating device for metal decorative panels includes a coating chamber 1. A sealing door 2 is located at the front end of the coating chamber 1, and an observation window 201 is located at the front end of the sealing door 2. A fixing frame 3 is fixedly connected to the upper inner wall of the coating chamber 1. Side plates 301 are fixedly connected to the front and rear sides of the lower end of the fixing frame 3. A drive mechanism 4 is fixedly installed at the upper end of the front side plate 301. A sliding groove 302 is provided through the middle of both the front and rear ends of the fixing frame 3. A pair of clamping mechanisms 5 are slidably installed on the fixing frame 3 through the sliding grooves 302. A flipping mechanism 6 is located at the outer end of the clamping mechanism 5, and a coating assembly 7 is located below the clamping mechanism 5. When this device is in use, the drive mechanism... 4 drives two clamping mechanisms 5 to move, thereby clamping or releasing the substrate by driving the two clamping mechanisms 5 to move towards or away from each other. The clamping mechanism 5 can apply pressure evenly through the buffer spring 506 inside, preventing the plate from deforming or warping due to excessive or uneven clamping force. After clamping, the clamped metal plate is coated by the coating assembly 7. During single-sided processing, the angle and direction of the metal plate can be freely adjusted by the flipping mechanism 6. After single-sided processing is completed, the metal plate is flipped by the flipping mechanism 6 to facilitate processing of the other side, improving the practicality and flexibility of the device.

[0023] Specifically, in this embodiment, the driving mechanism 4 includes a bidirectional motor 401, which is fixedly mounted on the upper end of the side plate 301. Both output ends of the bidirectional motor 401 are fixedly connected to threaded screws 402. The other end of the threaded screws 402 is rotatably connected to the inner wall of the coating chamber 1. A moving block 403 is threadedly connected to the surface of the threaded screws 402, and a connecting block 404 is fixedly connected to the surface of the moving block 403. The other end of the connecting block 404 is fixedly connected to the clamping mechanism 5. When the driving mechanism 4 is started, the bidirectional motor 401 drives the threaded screws 402 on both sides to rotate. The rotation of the threaded screws 402 then drives the moving block 403 to move. The moving block 403 then drives the moving plate 501 to move through the connecting block 404, thereby driving the two clamping mechanisms 5 to move towards or away from each other, thus achieving the clamping or releasing of the substrate.

[0024] Specifically, in this embodiment, the clamping mechanism 5 includes a movable plate 501. Slider 502s are fixedly connected to both the front and rear ends of the movable plate 501. The other end of the slider 502 is slidably connected to the fixed frame 3 via a groove 302. The rear slider 502 extends out of the groove 302 and is fixedly connected to the connecting block 404. A pair of anti-collision bars 8 are fixedly connected to the outer end of the movable plate 501. The anti-collision bars 8 are used to protect the flipping mechanism 6, preventing the flipping cylinder 601 in the flipping mechanism 6 from colliding with the side of the fixed frame 3 under the drive of the driving mechanism 4, thereby protecting the cylinder's safety.

[0025] Specifically, in this embodiment, a rotating block 503 is rotatably mounted on the inner end of the movable plate 501. A turntable 504 is fixedly connected to the other end of the rotating block 503. A pair of telescopic rods 505 are symmetrically arranged on the other end of the turntable 504. An L-shaped clamping plate 507 is fixedly connected to the other end of each telescopic rod 505. A buffer spring 506 is sleeved on the outer side of each telescopic rod 505. Both ends of the buffer spring 506 are fixedly connected to the turntable 504 and the L-shaped clamping plate 507, respectively. The driving mechanism 4 drives the two movable plates 501 to move towards or away from each other, thereby clamping or releasing the substrate. During clamping, the clamping mechanism 5, through the cooperation of the telescopic rods 505 and the buffer springs 506, ensures that the L-shaped clamping plate 507 applies pressure evenly during clamping, preventing deformation or warping of the substrate due to excessive or uneven clamping force, thus guaranteeing the subsequent coating effect.

[0026] Specifically, in this embodiment, the upper end of the L-shaped clamping plate 507 is slidably connected to both the front and rear sides with fixing rods 508. The upper ends of the two fixing rods 508 are fixedly connected to the lower end of the pressure plate 5010, and a spring member 509 is provided on the outer side of the lower fixing rod 508. The L-shaped clamping plate 507, in conjunction with the pressure plate 5010, can clamp the metal sheet in multiple directions, ensuring the stability of the clamping.

[0027] Specifically, in this embodiment, the flipping mechanism 6 includes a flipping cylinder 601, which is fixedly installed on the outer side of the right moving plate 501. The output end of the flipping cylinder 601 is fixedly connected to a toothed plate 602. The upper end of the toothed plate 602 is meshed with a gear 603. The gear 603 is rotatably installed on the right end of the moving plate 501, and the left end of the gear 603 is connected to the rotating block 503 via a transmission rod. After the clamping mechanism 5 clamps the metal sheet, the coating component 7 coats the clamped metal sheet. After the coating process is completed, the flipping mechanism 6 is activated. The flipping cylinder 601 drives the toothed plate 602 to move, which in turn causes the toothed plate 602 to drive the gear 603 to rotate. The rotation of the gear 603 then drives the rotating block 503 to rotate through the transmission rod. The flipping mechanisms 6 on both sides cause the two rotating blocks 503 to rotate in the same direction, which in turn causes the rotating block 503 to drive the turntable 504 to rotate. The angle and direction of the metal sheet can be freely adjusted to flip the metal sheet, making it easier to process the other side and improving the practicality and flexibility of the device.

[0028] Specifically, in this embodiment, a guide rod 605 is fixedly connected to the left end of the toothed plate 602, and the other end of the guide rod 605 is disposed inside the guide groove 604, which is located at the right end of the right movable plate 501. The guide rod 605 and the guide groove 604 cooperate with each other to limit and guide the toothed plate 602, preventing it from deviating during movement and thus ensuring the stability of the flipping mechanism 6.

[0029] The working principle of this utility model is as follows: When this device is used, the drive mechanism 4 is started, and the bidirectional motor 401 drives the threaded screws 402 on both sides to rotate. The rotation of the threaded screws 402 drives the moving block 403 to move. The moving block 403 then drives the moving plate 501 to move through the connecting block 404. The drive mechanism 4 drives the two moving plates 501 to move towards or away from each other, thereby clamping or releasing the substrate. During the clamping process, the clamping mechanism 5 cooperates with the telescopic rod 505 and the buffer spring 506 to ensure that the L-shaped clamping plate 507 can apply pressure evenly during the clamping process, preventing the plate from deforming or warping due to excessive or uneven clamping force, thus ensuring the effect of subsequent coating. At the same time, the L-shaped clamping plate 507, together with the pressure plate 5010, can clamp the metal plate in multiple directions to ensure the stability of the clamping.

[0030] After the clamping mechanism 5 clamps the metal sheet, the coating component 7 coats the clamped metal sheet. During single-sided processing: the flipping cylinder 601 drives the toothed plate 602 to move, which in turn drives the gear 603 to rotate. The rotation of the gear 603 then drives the rotating block 503 to rotate through the transmission rod. The flipping mechanisms 6 on both sides cause the two rotating blocks 503 to rotate in the same direction, which in turn drives the turntable 504 to rotate. The angle and direction of the metal sheet can be freely adjusted. After single-sided processing is completed, the flipping mechanism 6 flips the metal sheet to facilitate processing the other side, improving the practicality and flexibility of the device.
