Description

Technical Field

[0001] This utility model belongs to the field of coating technology, and more specifically, relates to a coating device. Background Technology

[0002] Vacuum deposition is a technique for producing thin film materials. In a vacuum deposition chamber, atoms of the material are separated from a heating source and deposited onto the surface of the object to be coated. Vacuum deposition is an important aspect of vacuum applications. It is based on vacuum technology, utilizing physical or chemical methods, and incorporating a series 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. Simply put, vacuum deposition is the method of evaporating or sputtering a metal, alloy, or compound (called a target material) in a vacuum, causing it to solidify and deposit on the object to be coated (called a substrate).

[0003] A search revealed that Chinese patent CN220952019U discloses a coating structure and coating device, which includes a coating box, an electric rotating disk, and a hanging bracket. The electric rotating disk is disposed inside the coating box, and the hanging bracket is disposed on one side of the electric rotating disk. The moving component includes a driving component, a moving base, and a coating component. The driving component is correspondingly disposed inside the coating box, the moving base is disposed on one side of the driving component, and the coating component is disposed on one side of the moving base. In use, the workpiece is placed on the hanging bracket 1, the electric rotating disk drives the hanging bracket to rotate, and the driving component drives the coating component to move up and down through the moving base to coat the workpiece at different positions on the hanging bracket, thereby ensuring that the workpiece at each position is coated evenly.

[0004] Although the above technical solution has successfully completed the coating of the workpiece, after completing one round of coating, the coated workpiece needs to be unloaded from the rack and then loaded back into the rack before the next round of coating can be carried out. This results in poor continuity of the coating operation, with a lot of time spent loading and unloading workpieces in between, which reduces the overall coating efficiency and increases the production cycle.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] See Figure 1-4As shown, a coating apparatus includes a coating box 1 with a door at the front end. The coating box 1 contains a hanging mechanism 2, an electric rotating disk mechanism 3, a lifting mechanism 4, a coating mechanism 5, and a pair of spaced-apart first guide rails 6. The hanging mechanism 2 is located above the pair of first guide rails 6, and a pulley 7 adapted to the pair of first guide rails 6 is provided at the lower end of the hanging mechanism 2. The hanging mechanism 2 can slide within the coating box 1 through the cooperation of the pulley 7 and the first guide rails 6. The electric rotating disk mechanism 3 is located within the lifting mechanism 5. The electric rotating disk mechanism 3 is driven by the lifting mechanism 4 to move up and down, and after moving up, it can drive the hanging rack 21 in the hanging rack mechanism 2 to rotate; the coating mechanism 5 is located on one side of the hanging rack 21, and the coating mechanism 5 is used to coat the workpieces hanging on the hanging rack 21; the door of the coating box 1 is provided with an observation port 11, which allows the operator to observe the status of the coating process inside the coating box, the uniformity of the coating, and the changes on the surface of the workpiece in real time without opening the door, so as to ensure the coating quality.

[0037] Further, see Figure 5 As shown, in this embodiment, the hanging mechanism 2 includes a hanging bracket 21, the lower end of which passes through a support plate 22. A pulley 7 is mounted on the support plate 22. The support plate 22, through the pulley 7 and the first guide rail 6, can slide within the coating chamber 1, thereby causing the hanging bracket 21 to slide within the coating chamber 1. In this embodiment, to prevent the hanging bracket 21, which passes through the support plate 22, from rotating relative to the support plate 22 during non-coating operations, see [reference needed]. Figure 6-7 As shown, the lower end of the bracket 21 is provided with a pair of opposing first positioning pins 211, and the upper end of the support plate 22 is provided with second positioning holes 222 corresponding to the first positioning pins 211. During coating, when the support plate 22 drives the bracket 21 to slide to the coating position, the electric rotating disk mechanism 3 moves upward under the drive of the lifting mechanism 4, thereby lifting the bracket 21 upward in the support plate 22. After the bracket 21 is pulled out of the second positioning hole 222 corresponding to the positioning pin 211, the electric rotating disk mechanism 3 drives the bracket 21 to rotate.

[0038] In this embodiment, to avoid interference between the electric rotating disk mechanism 3 and the support plate 22 during the lifting of the hanging bracket 21, see [reference needed]. Figure 8 As shown, the lower end of the support plate 22 is provided with a clearance groove 221; in addition, in order to ensure that the support plate 22 drives the hanging bracket 21 to accurately slide and stop at the coating position, and to prevent the support plate 22 from moving upward with the hanging bracket 21 during the lifting of the hanging bracket 21 by the electric rotating disk mechanism 3, see [reference] Figure 1 and Figure 7-8 As shown, a pair of first guide rails 6 are respectively provided with a first limiting hole 61 and a threaded hole 62. The support plate 22 is provided with a through hole 223 that matches the first limiting hole 61 and the threaded hole 62. During coating, the position of the support plate 22 is limited by inserting a limiting pin 9 between the first limiting hole 61 and the through hole 223. The support plate 22 is fixed by locking the corresponding locking bolt between the threaded hole 62 and the through hole 223.

[0039] Further, see Figure 9-10 As shown, in this embodiment, the electric rotating disk mechanism 3 includes an electric rotating disk body 31, on which a turntable 32 is provided. When the hanging bracket 21 is driven to rotate, the upper surface of the turntable 32 abuts against the bottom surface of the hanging bracket 21. In order to ensure that the electric rotating disk body 31 drives the hanging bracket 21 to rotate synchronously with it through the turntable 32, a pair of opposing second positioning pins 33 are provided on the turntable 32. The lower end of the hanging bracket 21 is provided with first positioning holes 212 corresponding to the second positioning pins 33. When the hanging bracket 21 is driven to rotate, the second positioning pins 33 pass through the corresponding first positioning holes 212.

[0040] In this embodiment, a pair of opposing sensing plates 34 are also provided on the turntable 32. Each pair of sensing plates 34 is adapted to a U-shaped photoelectric switch 35. The U-shaped photoelectric switch 35 is fixed on the lifting mechanism 4 by a corresponding support. Through the cooperation of the sensing plates 34 and the corresponding U-shaped photoelectric switches 35, the stop position of the turntable 32 can be precisely controlled, thereby ensuring that when the hanging bracket 21 is driven to rotate, the second positioning pin 33 can be accurately inserted into the corresponding first positioning hole 212.

[0041] Further, see Figure 11 As shown, in this embodiment, the lifting mechanism 4 includes a movable plate 41. A first guide shaft 43 passes through the movable plate 41 via a linear bearing 42. A fixed plate 44 is provided at the lower end of the first guide shaft 43. A lifting cylinder 45 is provided on the fixed plate 44. The front end of the output shaft of the lifting cylinder 45 is connected to the bottom surface of the movable plate 41 via a connecting plate 46. A fixed shaft 47 is provided on the upper surface of the movable plate 41, and a lifting plate 48 is provided at the upper end of the fixed shaft 47. For installation, see... Figure 3-4As shown, the upper end of the first guide shaft 43 is fixedly connected to the inner panel of the coating box 1, the fixed shaft 47 slidably passes through the inner panel of the coating box 1, and the electric rotating disk body 31 is fixed on the lifting plate 48. The U-shaped photoelectric switch 35 is fixed on the lifting plate 48. When the hanging bracket 21 is driven to rotate, the piston rod of the lifting cylinder 45 extends, driving the movable plate 41 to move upward along the first guide shaft 43, thereby driving the fixed shaft 47 to move upward, thereby driving the lifting plate 48 to move upward, thereby driving the electric rotating disk body 31 to move upward, thus realizing the lifting of the hanging bracket 21 by the turntable 32 and driving the rotation by the electric rotating disk body 31.

[0042] In this embodiment, the lifting mechanism 4 also includes a limiting bolt 49. During installation, the limiting bolt 49 slidably passes through the fixed plate 44, and its upper end is connected to the movable plate 41. The limiting bolt 49 provides a hard limit on the upward movement distance of the movable plate 41, thereby limiting the lifting height of the hanging bracket 21. Of course, the above is only one implementation method and is not intended to limit the position of this application. In actual installation, other methods can also be used, such as setting a magnetic switch (not shown in the figure) on the outer surface of the lifting cylinder 45.

[0043] Further, see Figure 12 As shown, in this embodiment, the coating mechanism 5 includes a driving component 51, a movable seat 52, and a coating component 53 capable of coating the workpiece. During installation, the driving component 51 is disposed inside the coating box 1, the movable seat 52 is disposed on the driving component 51, and the coating component 53 is disposed on the movable seat 52. During coating, the movable seat 52 moves up and down under the drive of the driving component 51, thereby driving the coating component 53 to move up and down, thus realizing the coating operation.

[0044] In this embodiment, the driving component 51 includes a lead screw 511, one end of which is connected to a motor 513 via a coupling 512. A second guide shaft 514 is respectively disposed on both sides of the lead screw 511, and the direction of the second guide shafts 514 is parallel to that of the lead screw 511. For installation, see [reference needed]. Figure 2As shown, the lead screw 511 is rotatably disposed inside the coating chamber 1, the second guide shaft 514 is fixedly connected to the coating chamber 1, and the motor 513 is fixed to the coating chamber 1 by a motor bracket. At this time, both the lead screw 511 and the second guide shaft 514 pass through the movable seat 52, wherein the lead screw 511 is threadedly connected to the movable seat 52, and the second guide shaft 514 is slidably connected to the movable seat 52. During coating, the motor 513 drives the lead screw 511 to rotate through the coupling 512, thereby driving the movable seat 52 to move up and down along the second guide shaft 514, thereby driving the coated part 53 to move up and down.

[0045] Further, see Figure 13 As shown, the device also includes an auxiliary loading and unloading vehicle 8, which is a scissor-type lifting trolley. A pair of second guide rails 81 are provided on the upper surface of the scissor-type lifting trolley. The distance between the pair of second guide rails 81 is the same as the distance between the pair of first guide rails 6. During coating, when the end faces of the second guide rails 81 and the first guide rails 6 come together and align, the hanging mechanism 2 can slide between the scissor-type lifting trolley and the coating box 1.

[0046] In this embodiment, a pin hole 811 is provided on the second guide rail 81 to match the through hole 223 of the support plate 22 in the hanging mechanism 2; when the hanging mechanism 2 slides onto the scissor lift trolley, the limiting pin 9 is inserted into the pin hole 811 and the matching through hole 223, thereby limiting the hanging mechanism 2 on the scissor lift trolley.

[0047] The working principle of this utility model is as follows:

[0048] During coating, the operator first places the hanger mechanism 2 on the auxiliary loading and unloading vehicle 8, then loads the workpiece to be coated onto the hanger 21; after loading, the hanger 21 is pushed to the coating box 1 via the auxiliary loading and unloading vehicle 8, and after opening the box door, the height of the hanger 21 is adjusted via the auxiliary loading and unloading vehicle 8, and the position is adjusted in conjunction with the auxiliary loading and unloading vehicle 8, so that the end faces of the second guide rail 81 and the first guide rail 6 are brought together and aligned. Then, the limiting pin 9 is pulled out from the pin hole 811 and its matching through hole 223; then the hanger mechanism 2 is pushed towards the coating box 1, and the hanger mechanism 2 is moved to the coating box 1. After positioning, a limiting pin 9 is inserted between the first limiting hole 61 and its matching through hole 223, and a corresponding locking bolt is locked between the threaded hole 62 and its matching through hole 223 to complete the coating loading; then the box door is closed, the lifting cylinder 45 is started, the piston rod of the lifting cylinder 45 is extended, and the electric rotating disk mechanism 3 is driven to move upward, raising the hanging frame 21 to the set height, and then the electric rotating disk mechanism 3 and the motor 513 are started, so that the hanging frame 21 rotates while the coating part 53 moves up and down, so as to achieve coating on the workpiece on the hanging frame 21.

[0049] After the coating is completed, stop the electric rotary disk mechanism 3 and the motor 513, start the lifting cylinder 45, and retract the piston rod of the lifting cylinder 45. At this time, the hanging bracket 21 moves downward and resets under the action of gravity. Then, after opening the box door, push the empty auxiliary loading and unloading vehicle 8, and bring the end faces of the second guide rail 81 and the first guide rail 6 together. After removing the limit pin 9 and the locking bolt, pull the hanging bracket mechanism 2 to slide it onto the empty auxiliary loading and unloading vehicle 8. Insert the limit pin 9 between the two to complete the unloading. Push it away directly, and load the other auxiliary loading and unloading vehicle 8, which is loaded with the workpiece to be coated, in the same way as above. It will not be repeated here.

[0050] Once the workpiece has been coated, the auxiliary loading and unloading vehicle 8 pushes it to the unloading area. After unloading the coated workpiece, a new workpiece to be coated is loaded in and pushed to one side of the coating box 1, ready for the next round of coating.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
