[0002] The principle of PVD coating technology is to use low-voltage, high-current arc discharge technology under vacuum conditions. The gas discharge evaporates the target material and ionizes the evaporated material. Under the action of the electric field, the evaporated material or its reaction products are deposited on the workpiece. The film deposited using PVD coating technology has the characteristics of high hardness and wear resistance (low friction coefficient), excellent corrosion resistance and chemical stability, and the film life is longer. However, during the coating process, the coating material easily drips onto the coating baffle / cooling baffle, making it difficult to clean the coating baffle / cooling baffle.

[0036] This application provides a coating mechanism, such as Figures 1 to 5 As shown, the coating mechanism includes a pulling unit 400 and a cooling baffle 100, a coating baffle 200 and a disposable film 300 arranged in sequence; the pulling unit 400 is connected to the disposable film 300, and the pulling unit 400 can drive the disposable film 300 to move relative to the coating baffle 200.

[0037] The above-described coating mechanism sequentially arranges a cooling baffle 100, a coating baffle 200, and a disposable film 300. Specifically, the disposable film 300 is disposed on the side of the coating baffle 200 facing away from the cooling baffle 100. During coating, coating material can drip onto the disposable film 300, eliminating the need to clean the coating baffle 200 and the cooling baffle 100. Furthermore, a pulling unit 400 is connected to the disposable film 300. When coating material drips onto the disposable film and replacement is required, the disposable film 300 is pulled relative to the coating baffle 200 by the disposable film 300, thereby directly removing the disposable film 300 with the coating material. The coating mechanism of the present application eliminates the need to clean the coating baffle 200 and the cooling baffle 100; the disposable film 300 can be cleaned simply by pulling the disposable film 300 with the pulling unit 400.

[0038] Specifically, the cooling baffle 100 , the coating baffle 200 and the disposable film 300 are pressed into contact in sequence.

[0039] Specifically, if Figure 1 and Figure 2 As shown, the cooling baffle 100 includes a first arc-shaped portion and a first straight plate portion connected to each other, and the first straight plate portion is provided on both sides of the first arc-shaped portion; the coating baffle 200 includes a second arc-shaped portion and a second straight plate portion connected to each other, and the second straight plate portion is provided on both sides of the second arc-shaped portion; the disposable film 300 includes a third arc-shaped portion and a third straight plate portion connected to each other, and the third straight plate portion is provided on both sides of the third arc-shaped portion.

[0040] In some embodiments, after the pulling unit 400 pulls the disposable film 300 to move, the disposable film 300 with the coating material can be separated from the coating baffle 200 , and then a layer of disposable film 300 can be laid on the coating baffle 200 again.

[0041] In some embodiments, the disposable film 300 is provided with multiple layers, and the pulling unit 400 is connected to the disposable film 300 farthest from the coating baffle 200. When multiple layers of disposable films 300 are provided, the pulling unit 400 is connected to the disposable film 300 farthest from the coating baffle 200, that is, the pulling unit 400 is connected to the outermost disposable film 300. When the pulling unit 400 pulls the disposable film 300 to move, the disposable film 300 with the coating material can be separated from the coating baffle 200, and then a new disposable film 300 can be exposed. Then the pulling unit 400 is connected to the disposable film 300 farthest from the coating baffle 200, and the action can be repeated. The present application provides multiple layers of disposable films 300, and there is no need to lay the disposable film 300 again after each pulling unit 400 works, which reduces the difficulty of work and improves work efficiency.

[0042] In some embodiments, as Figure 1 and Figure 2 As shown, the pulling unit 400 includes a mounting rod 410, a mounting sleeve 420, a connecting plate 430, and a first elastic member. The mounting rod 410 is connected to the coating baffle 200. The mounting sleeve 420, connecting plate 430, and the first elastic member are all mounted on the mounting rod 410. The mounting sleeve 420 is connected to the connecting plate 430 via the first elastic member. The connecting plate 430 is connected to the disposable film 300. The mounting sleeve 420 can drive the connecting plate 430 and the disposable film 300 to move. The mounting sleeve 420 and connecting plate 430 are mounted on the mounting rod 410, and the connecting plate 430 is connected to the disposable film 300. By pulling the mounting sleeve 420, the connecting plate 430 and the connected disposable film 300 can be moved. The first elastic member is mounted on the mounting rod 410, and the mounting sleeve 420 and connecting plate 430 are connected via the first elastic member. The first elastic member uses its own elastic force to reset the mounting sleeve 420 and connecting plate 430.

[0043] Specifically, if Figure 1 and Figure 2 As shown, in this embodiment, the mounting rod 410 of the pulling unit 400 is connected to the second arc-shaped portion of the coating baffle 200 , and the connecting plate 430 is connected to the third arc-shaped portion of the disposable film 300 .

[0044] In other embodiments, the mounting rod 410 of the pulling unit 400 is connected to any area of ​​the coating baffle 200, and the connecting plate 430 is connected to any area of ​​the disposable film 300, as long as the connecting plate 430 can move to drive the connected disposable film 300 to move.

[0045] Specifically, the first elastic member is a spring.

[0046] Specifically, if Figure 1 and Figure 2 As shown, the pulling unit 400 also includes a movable plate 440, which is pivotally connected to the mounting sleeve 420 and is designed to be grasped by a human hand. The movable plate 440 is connected to the mounting sleeve 420 and is designed to be grasped by a human hand. By pulling the movable plate 440, a worker can move the mounting sleeve 420, the connecting plate 430, and the disposable film 300 connected to the connecting plate 430. When the worker is able to pull the movable plate 440 outward (away from the mounting rod 410), the first elastic member is stretched. When the worker releases the grip and no external force is applied, the first elastic member returns to its original position under its own elastic force, thereby causing the movable plate 440, the mounting sleeve 420, and the connecting plate 430 to return to their original position.

[0047] More specifically, the movable plate 440 and the mounting sleeve 420 are rotatably connected via a rotating shaft.

[0048] In this embodiment, if Figure 1 and Figure 2 As shown, the mounting rod 410 of the pulling unit 400 is connected to the second arc portion of the coating baffle 200. Four groups of pulling units 400 are provided, with two groups of pulling units 400 provided on one side of the second arc portion and two groups of pulling units 400 provided on the other side.

[0049] In some embodiments, as Figures 1 to 5 As shown, the coating mechanism further includes a limiting unit 500, which includes a limiting rod 510 and a limiting groove 520. One of the limiting rod 510 and the limiting groove 520 is provided on the coating baffle 200, and the other is provided on the cooling baffle 100. The limiting rod 510 can extend into the limiting groove 520 to define the relative position of the coating baffle 200 and the cooling baffle 100. By providing the limiting unit 500, when one of the limiting rod 510 and the limiting groove 520 is provided on the coating baffle 200 and the other is provided on the cooling baffle 100, when the coating baffle 200 and the cooling baffle 100 are installed, the limiting rod 510 can extend into the limiting groove 520, thereby defining the relative position of the coating baffle 200 and the cooling baffle 100.

[0050] In this embodiment, if Figures 3 to 5As shown, a limiting rod 510 is provided on the second straight plate portion of the coating baffle 200 , and a limiting groove 520 is provided on the first straight plate portion of the cooling baffle 100 .

[0051] In other embodiments, the limiting groove 520 is provided in any area of ​​the coating baffle 200 , and the limiting rod 510 is provided in any area of ​​the cooling baffle 100 , as long as the limiting unit 500 and the pulling unit 400 do not affect each other.

[0052] Specifically, if Figures 1 to 5 As shown, the limiting unit 500 further includes a second elastic member 530, the two ends of which respectively abut the limiting rod 510 and the wall of the limiting groove 520. The second elastic member 530 is used to use its own elastic force to push the limiting rod 510 toward the direction of leaving the limiting groove 520. By providing the second elastic member 530, the two ends of the second elastic member 530 respectively abut the limiting rod 510 and the wall of the limiting groove 520. When the coating baffle 200 and the cooling baffle 100 are in contact with each other, the limiting rod 510 extends into the limiting groove 520 and the second elastic member 530 is compressed. When no external force is applied, the second elastic member 530 returns to its original position, and the elastic force of the second elastic member 530 pushes the limiting rod 510 toward the direction of leaving the limiting groove 520, thereby separating the coating baffle 200 and the cooling baffle 100. The present application provides a limiting unit 500 so that the coating baffle 200 can be quickly and conveniently disassembled and assembled, making it more convenient for staff to use.

[0053] Specifically, the second elastic member 530 is a spring, and the elastic deformation direction of the second elastic member 530 is parallel to the arrangement direction of the coating baffle 200 and the cooling baffle 100 .

[0054] Specifically, if Figures 3 to 5 As shown, the limiting unit 500 further includes a supporting plate 540 , and the limiting rod 510 is connected to the second elastic member 530 via the supporting plate 540 .

[0055] Furthermore, if Figures 3 to 5As shown, a limiting rod 510 is provided on the coating baffle 200, and a limiting groove 520 is provided on the cooling baffle 100. The coating mechanism further includes a disassembly unit 600, which includes a pull rod 610 and a clamping member 620. One end of the pull rod 610 is provided outside the cooling baffle 100, and the other end passes through the cooling baffle 100 and extends into the limiting groove 520. The clamping member 620 is provided in the limiting groove 520 and is connected to the pull rod 610. The clamping member 620 can be clamped to the limiting rod 510. By providing the disassembly unit 600, the clamping member 620 of the disassembly unit 600 extends into the limiting groove 520 and clamps to the limiting rod 510, thereby preventing the limiting rod 510 from being disengaged from the limiting groove 520, thereby limiting the relative position of the coating baffle 200 and the cooling baffle 100. When the coating baffle 200 and the cooling baffle 100 need to be disassembled, the pull rod 610 is pulled, and the pull rod 610 drives the clamping part 620 to move, so that the clamping part 620 is separated from the limiting rod 510. At this time, the limiting rod 510 can move in the direction away from the limiting groove 520 under the elastic action of the second elastic part 530.

[0056] Specifically, if Figures 3 to 5 As shown, the disassembly and assembly unit 600 further includes a third elastic member 630. The third elastic member 630 is located within the limiting groove 520 and is sleeved on the pull rod 610. One end of the third elastic member 630 abuts against the groove wall of the limiting groove 520, and the other end abuts against the clamping member 620. By providing the third elastic member 630, the third elastic member 630 is sleeved on the pull rod 610, and the two ends of the third elastic member 630 can respectively abut against the groove wall of the limiting groove 520 and the clamping member 620. The third elastic member 630 can drive the pull rod 610 and the clamping member 620 to reset through its own elastic force.

[0057] More specifically, the third elastic member 630 is a spring. When the staff pulls the pull rod 610 to move away from the coating baffle 200, the third elastic member 630 is compressed. When the staff lets go and there is no external force, the third elastic member 630 resets, thereby driving the pull rod 610 and the clamping member 620 to move toward the coating baffle 200.

[0058] In some embodiments, as Figures 3 to 5 As shown, a plurality of the limiting units 500 and the disassembling units 600 are provided, and the plurality of limiting units 500 corresponds one-to-one to the plurality of disassembling units 600. Providing a plurality of limiting units 500 improves the limiting effect, and the plurality of limiting units 500 corresponds one-to-one to the plurality of disassembling units 600, and each limiting unit 500 is limited or disassembled by the corresponding disassembling unit 600.

[0059] In this embodiment, if Figures 1 to 5As shown, the limiting rods 510 of the limiting unit 500 are provided on the two second straight plate portions of the coating baffle 200, and the limiting grooves 520 of the limiting unit 500 are provided on the two first straight rod portions of the cooling baffle 100. The two second straight rod portions and the two first straight rod portions correspond one to one, and the two limiting rods 510 and the two limiting grooves 520 correspond one to one.

[0060] More specifically, in this embodiment, if Figures 1 to 5 As shown, there are four groups of limit units 500, and each second straight rod portion is provided with two limit rods 510, and the two limit rods 510 are arranged along the length direction of the second straight rod portion. There are four groups of limit units 500, and four groups of disassembly units 600 are provided, and the four groups of disassembly units 600 correspond one to one with the four groups of limit units 500.

[0061] The present application also provides a coating device, including any of the above coating mechanisms. The coating device of the present application does not require cleaning of the coating baffle 200 and the cooling baffle 100. The disposable film 300 can be cleaned by simply pulling the disposable film 300 with the pulling unit 400.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
