Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a dirt-proof device for the window of a coating machine and a coating machine. Background Technology

[0002] In the vacuum coating process, the observation window is an essential component, allowing operators to observe the interior of the vacuum chamber in real time. This is crucial for monitoring the coating process and ensuring coating quality. However, during the continuous and sealed coating process, the observation window is prone to accumulating fog and dirt, which can affect the effectiveness of real-time observation.

[0003] In existing technologies, some coating machines use anti-fouling devices to block contaminants. These devices primarily rely on two rotatable semi-circular baffles for obstruction. When the two baffles overlap, the user can observe the interior of the coating machine. However, this method is rudimentary, as the other half of the viewing window is always blocked, affecting the user's field of vision. For operators who need a comprehensive view of the machine's interior, this is cumbersome, requiring manual rotation of the baffles to overlap each time observation is needed. This not only increases operational complexity but also leads to wear or loosening of the baffles due to frequent operation, affecting their sealing and anti-fouling effectiveness. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a dirt-proof device for the window of a coating machine, which aims to solve the technical problem that the baffle affects the field of view during the observation process in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A dirt-proof device for a coating machine window is installed on the observation window of the coating machine housing. The observation window includes a first fixing part fixed to the outside of the coating machine housing and a second fixing part disposed on the inside of the coating machine housing, and a glass window fixed between the first fixing part and the second fixing part. The dirt-proof device for the coating machine window includes a dust cover for blocking the observation window on the side of the second fixing part away from the first fixing part, a rotating mechanism for driving the dust cover to open and close on the side of the second fixing part near the dust cover, a transparent observation plate on the end of the first fixing part away from the second fixing part, and a knob on one end of the transparent observation plate. The transparent observation plate is rotatably connected to the first fixing part through the knob. The dirt-proof device for the coating machine window also includes a traction rope passing through the inside and outside of the observation window for pulling the rotating mechanism to rotate. One end of the traction rope is connected to the rotating mechanism, and the end of the traction rope away from the rotating mechanism is connected to the knob.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: a dust cover is provided on the inner observation end of the observation window to prevent the internal coating layer and dust from entering the observation window. A rotating mechanism that can drive the dust cover to rotate is provided at the upper end of the observation window. One end of the traction rope that drives the rotating mechanism is led out to the outside of the coating machine housing and connected to the knob. Simply rotating the knob will drive the rotating mechanism and the transparent observation plate to rotate. The rotation of the rotating mechanism will drive the dust cover to rotate, realizing the function of opening the dust cover from the outside. After being flipped, the dust cover is completely away from the observation window and does not obstruct any observation view, making the observation view better. When the knob is rotated in the opposite direction, the dust cover returns to the blocking position under the combined action of gravity and the rotating mechanism.

[0008] According to one aspect of the above technical solution, the rotating mechanism is located on the upper side of the second fixed part. The rotating mechanism includes a pad block fixedly connected to the second fixed part. A spring plate is provided on the pad block. A force plate is provided at one end of the spring plate away from the pad block. A shaft is provided on the force plate. The shaft is located near both ends of the spring plate and passes through the force plate.

[0009] According to one aspect of the above technical solution, the spring plate includes a first spring plate portion fixedly connected to the force plate and a second spring plate portion fixedly connected to the pad block, and a third spring plate portion connected between the first spring plate portion and the second spring plate portion. The traction rope passes through the first spring plate portion and is connected to the force plate. The end of the traction rope away from the force plate passes through the second spring plate portion. The first spring plate portion and the second spring plate portion are perpendicular to each other in their natural state.

[0010] According to one aspect of the above technical solution, the first spring piece is provided with a roller for supporting the sliding of the traction rope.

[0011] According to one aspect of the above technical solution, a support plate for supporting the force-bearing plate is provided between the pad block and the spring plate.

[0012] According to one aspect of the above technical solution, the dust cover includes a dust cover body and two brackets. The two brackets are located at both ends of the force-bearing plate. The brackets are detachably connected to the force-bearing plate through the shaft. The end of the bracket away from the force-bearing plate extends to the rear side of the dust cover and is fixedly connected to the dust cover.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please see Figures 1 to 2 An embodiment of the present invention provides a dirt-proof device for a coating machine window, which is installed on the observation window 1 of the coating machine housing. The observation window 1 includes a first fixing part 11 fixed to the outside of the coating machine housing and a second fixing part 12 disposed on the inside of the coating machine housing, and a glass window 13 fixed between the first fixing part 11 and the second fixing part 12. The dirt-proof device for the coating machine window includes a dust cover 2 disposed on the side of the second fixing part 12 away from the first fixing part 11 for covering the observation window 1. The side of the second fixing part 12 near the dust cover 2 is provided with a rotating mechanism 3 for driving the dust cover 2 to open and close. The end of the first fixing part 11 away from the second fixing part 12 is provided with a transparent observation plate 5, and one end of the transparent observation plate 5 is provided with a knob 6. The transparent observation plate 5 and the first fixing part 11 are rotatably connected through the knob 6. The dirt-proof device for the coating machine window also includes a traction rope 4 that passes through the inside and outside of the observation window 1 for pulling the rotating mechanism 3 to rotate. One end of the traction rope 4 is connected to the rotating mechanism 3, and the end of the traction rope 4 away from the rotating mechanism 3 is connected to the knob 6.

[0032] The anti-fouling device for the coating machine window of this utility model is simple to operate. Simply rotate the knob 6 on the outside. When the knob 6 is rotated, the traction rope 4 is pulled to rotate the rotating mechanism 3, which in turn drives the dust cover 2 to rotate and open the dust cover 2. At the same time, rotating the knob 6 drives the transparent observation plate 5 to rotate. When the transparent observation plate 5 is opened to the correct position, the dust cover 2 is also opened to the correct position. Then, the internal condition of the coating machine can be observed through the observation window 1.

[0033] See Figure 4 Furthermore, the rotating mechanism 3 is located on the upper side of the second fixed part 12. The rotating mechanism 3 includes a pad 31 fixedly connected to the second fixed part 12. The pad 31 is provided with a spring plate 32. The end of the spring plate 32 away from the pad 31 is provided with a force plate 33. The force plate 33 is provided with a shaft 34. The shaft 34 is located near both ends of the spring plate 32 and passes through the force plate 33. It should be noted that the rotating mechanism 3 can also be located on the side of the second fixed part 12. When located on the side, the dust cover 2 relies entirely on the rebound force of the spring plate 32 to return to the blocking position when returning. At the beginning of the return, jamming may easily occur. However, when located at the upper end, the dust cover 2 can return to the blocking position by the combined force of its own weight and the rebound force of the spring plate 32 when returning. The return is initiated by the weight of the dust cover 2, making the entire return process smoother.

[0034] Furthermore, the spring plate 32 includes a first spring piece 321 fixedly connected to the force plate 33, a second spring piece 322 fixedly connected to the pad block 31, and a third spring piece 323 connected between the first spring piece 321 and the second spring piece 322. The traction rope 4 passes through the first spring piece 321 and is connected to the force plate 33. The end of the traction rope 4 away from the force plate 33 passes through the second spring piece 322. The first spring piece 321 and the second spring piece 322 are perpendicular to each other in their natural state. Under the tension of the traction rope 4, the first spring piece 321 moves closer to the second spring piece 322, thereby achieving a flip. After the traction rope 4 is released, under the rebound force of the third spring piece 323, the first spring piece 321 eventually returns to a state perpendicular to the second spring piece 322, thus completing the covering of the dust cover 2.

[0035] See Figure 4In this embodiment, a roller 35 is provided on the first spring piece 321. The roller 35 is located at the lower end of the traction rope 4, so that the traction rope 4 can pass around the roller 35 and then pass through in a direction perpendicular to the second spring piece 322. By providing the roller 35, the force along the direction of the traction rope 4 during the pulling process can be redirected by the roller 35, and the tension can be directly and perpendicularly applied to the force plate 33, making it easier to bend the spring plate 32 and thus making it easier to open the dust cover 2. In addition, the roller 35 can be used to limit the first spring piece 321 and the second spring piece 322 when the spring plate 32 is fully bent, avoiding over-pulling and damage to the spring pieces. Preferably, the first spring piece 321 is provided with a roller 35 for supporting the sliding of the traction rope 4.

[0036] See Figure 4 In some embodiments, a support plate 36 is provided between the pad 31 and the spring plate 32 to support the force plate 33. By providing the support plate 36, the force plate 33 is supported and limited after the spring plate 32 rebounds, thereby preventing the dust cover 2 from directly impacting the observation window 1.

[0037] Furthermore, in some embodiments, the dust cover 2 includes a dust cover body 21 and two supports 22. The two supports 22 are located at both ends of the force plate 33. The supports 22 are detachably connected to the force plate 33 through the shaft 34. The end of the support 22 away from the force plate 33 extends to the rear side of the dust cover 2 and is fixedly connected to the dust cover 2. The dust cover 2 and the force plate 33 are detachably connected, which facilitates the adjustment and replacement of the dust cover 2 in the later stages.

[0038] Furthermore, the dust cover 2 is provided with a buffer pad 23 on the side near the observation window 1. By providing the buffer pad 23, the risk of noise and damage caused by the impact between the dust cover 2 and the observation window 1 when the dust cover 2 is covering it can be avoided. In addition, the buffer pad 23 is made of rubber material, which makes the seal between the dust cover 2 and the observation window 1 better.

[0039] See Figure 3 Furthermore, in this embodiment, the knob 6 includes a knob body 61 and a screw 62. The screw 62 passes through the transparent observation plate 5, and the end of the screw 62 away from the knob body 61 is threadedly connected to the first fixing part 11. The screw 62 is fixedly connected to the transparent observation plate 5. It can be understood that by rotating the knob body 61, the transparent observation plate 5 can be rotated. Since one end of the traction rope 4 is fixedly connected to the screw 62, the traction rope 4 will also be pulled when the knob 6 is rotated. It should be noted that when the transparent observation plate 5 is rotated to the fully open position, the traction rope 4, under the winding traction of the screw 62, makes the dust cover 2 just in the fully open position.

[0040] The present invention also provides a coating machine, including a dirt-proof device for the coating machine window of any of the above-mentioned coating machine, wherein the coating machine is provided with an observation window, and the dirt-proof device for the coating machine window is installed on the observation window.

[0041] In summary, the anti-fouling device for the coating machine window in the above embodiments of this utility model has a dust cover installed on the side of the observation window to prevent the internal coating layer and dust from entering the observation window and adhering to the glass, thus blocking the observation view. A rotating mechanism is provided on the second fixed part of the observation window, wherein the rotating mechanism is equipped with a spring piece. By pulling the traction rope on the outside, the spring piece can be bent, thereby causing the rotating mechanism to rotate and drive the dust cover to flip, completing the opening operation of the dust cover. When closing the dust cover, simply release the traction rope, and the dust cover will return to the covered position under the combined action of its own weight and the rebound force of the spring piece. It can be seen that the anti-fouling device for the coating machine window of this utility model is simple to operate and does not obstruct the observation view of the observation window when opened.
