Description

Technical Field

[0001] This utility model relates to the field of vacuum coating machine technology, specifically a grid plate mounting frame with anti-fouling mechanism and a coating machine. Background Technology

[0002] During the operation of a vacuum coating machine, coating processes take place inside the vacuum chamber. This process often generates splashed coating material particles or volatile impurities, which can easily move with the suction airflow towards the exhaust port, adhering to the grid mounting frame at the exhaust port and the inner wall surface of the vacuum chamber's exhaust port. Long-term accumulation of contaminants not only increases the difficulty of cleaning and maintaining the mounting frame and the inner wall of the exhaust port, but may also reduce the flow area of ​​the exhaust port, affecting suction efficiency. Furthermore, in subsequent operations, contaminants may detach and mix into the coating layer, adversely affecting the quality of the coated product and reducing the product yield.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] The existing coating machines mentioned above often generate splattered coating materials or volatile impurities during the coating process. After long-term operation, these contaminants accumulate on the inner walls of the mounting frame and the air extraction port, reducing the flow area of ​​the air extraction port and affecting extraction efficiency. Furthermore, in subsequent operations, these contaminants can easily detach and mix into the coating layer, affecting coating quality. The technical solution adopted by this utility model to solve these problems is as follows:

[0005] A grating mounting frame with an anti-fouling mechanism includes a mounting frame disposed at the air extraction port of a vacuum coating machine. The mounting frame is provided with a mounting part for mounting the grating and an anti-fouling plate for preventing contamination of the mounting frame and the inner wall of the air extraction port. The anti-fouling plate is located on the side of the mounting frame near the air extraction port and extends toward the interior of the vacuum chamber of the coating machine.

[0006] Furthermore, the anti-fouling panel includes a first anti-fouling panel arranged in a horizontal direction and a second anti-fouling panel arranged in a vertical direction, both of which are detachably connected to the mounting frame.

[0007] Furthermore, the first anti-fouling plate includes a first connecting plate arranged in a horizontal direction, and the first anti-fouling plate is threadedly connected to the mounting frame through the first connecting plate; the second anti-fouling plate includes a second connecting plate arranged in a vertical direction, and the second anti-fouling plate is threadedly connected to the mounting frame through the second connecting plate.

[0008] Furthermore, the first anti-fouling plate includes a first extension plate arranged parallel to the first connecting plate, and the second anti-fouling plate includes a second extension plate arranged parallel to the second connecting plate. Both the first extension plate and the second extension plate extend toward the interior of the vacuum chamber of the coating machine and are located on the side close to the central axis of the mounting frame.

[0009] Furthermore, the first anti-fouling panel includes a first transition panel, and the first extension panel is connected to the first connecting panel through the first transition panel; the second anti-fouling panel includes a second transition panel, and the second extension panel is connected to the second connecting panel through the second transition panel.

[0010] Furthermore, the two sides of the first transition plate are obliquely connected to the first connecting plate and the first extension plate, respectively, and have rounded corners; the two sides of the second transition plate are obliquely connected to the second extension plate and the second connecting plate, respectively, and have rounded corners.

[0011] Furthermore, the mounting part includes a plurality of mounting through holes spaced apart in the vertical direction on the mounting frame, and the second connecting plate is provided with a clearance notch adapted to the mounting through holes.

[0012] Furthermore, the second anti-fouling panel includes a shielding portion perpendicularly connected to the second extended panel. The shielding portion is located at the connection between the second extended panel and the first extended panel, and the cross-section of the shielding portion partially overlaps with the cross-section of the first extended panel.

[0013] Furthermore, the first anti-fouling panel is integrally formed; the second anti-fouling panel is integrally formed.

[0014] This utility model also provides a coating machine, including a coating chamber housing and a grid plate mounting frame with an anti-fouling mechanism as described above, which is connected to the coating chamber housing.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model provides a contamination-proof plate on the mounting frame. The plate is located on the side of the mounting frame near the exhaust port and extends towards the inside of the vacuum chamber of the coating machine. This prevents splashed coating materials or volatile impurities from directly adhering to the inner walls of the mounting frame and the exhaust port, significantly reducing the accumulation of contaminants in the exhaust port area and preventing the reduction of the exhaust port's flow area. This effectively solves the problem that existing coating machines often generate splashed coating materials or volatile impurities during the coating process. After long-term operation, these contaminants accumulate on the inner walls of the mounting frame and the exhaust port, resulting in a reduction of the exhaust port's flow area, affecting the exhaust efficiency. Furthermore, in subsequent operations, these contaminants are easily detached and mixed into the coating layer, affecting the coating quality.

[0017] 2. The first and second anti-fouling plates are detachably connected to the mounting frame, so that when the intercepted pollutants accumulate on the first and second anti-fouling plates, the user can remove them for maintenance or replacement, preventing subsequent detached pollutants from mixing into the coating layer, and reducing the overall maintenance burden of the air extraction port and the mounting frame.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Figure 4 This is the third schematic diagram of the connection between the mounting frame and the anti-fouling plate of this utility model. Detailed Implementation

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 The illustrated grating mounting frame with anti-fouling mechanism includes a mounting frame 1 located at the air extraction port of a vacuum coating machine. The mounting frame 1 is provided with a mounting part 2 for mounting the grating and an anti-fouling plate 3 for preventing the mounting frame 1 and the inner wall of the air extraction port from being contaminated. The anti-fouling plate 3 is located on the side of the mounting frame 1 near the air extraction port and extends toward the interior of the vacuum chamber of the coating machine.

[0025] This invention, by installing an anti-fouling plate on the mounting frame, with the plate located on the side of the mounting frame near the air extraction port and extending towards the interior of the vacuum chamber of the coating machine, can prevent splashed coating materials or volatile impurities from directly adhering to the inner walls of the mounting frame and air extraction port. This significantly reduces the accumulation of contaminants in the air extraction port area and avoids the reduction of the air extraction port's flow area. It effectively solves the problem that existing coating machines often generate splashed coating materials or volatile impurities during the coating process. After long-term operation, these contaminants accumulate on the inner walls of the mounting frame and air extraction port, resulting in a reduction of the air extraction port's flow area, affecting air extraction efficiency, and making it easy for contaminants to fall off and mix into the coating layer during subsequent operations, affecting the coating quality.

[0026] Optionally, in some embodiments, the mounting part 2 includes a bearing seat disposed opposite to the inner sidewall of the mounting frame 1, the grating plate includes a rotating shaft, the grating plate is disposed on the rotating shaft and rotates synchronously with the rotating shaft, thereby realizing the opening and closing control of the air extraction port, each bearing seat is provided with a shaft hole matching the end of the rotating shaft, the two ends of the rotating shaft are respectively embedded in the corresponding shaft hole, and a wear-resistant bushing can be provided on the inner wall of the shaft hole to reduce wear when the rotating shaft rotates and realize the flexible rotation of the grating plate.

[0027] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the mounting part 2 includes a mounting through hole 21 disposed opposite to the inner side wall of the mounting frame 1, the grille includes a rotating shaft, bearings are provided at both ends of the rotating shaft, the rotating shaft is mounted on the mounting through hole 21 through the bearings, the grille is disposed on the rotating shaft and rotates synchronously with the rotating shaft, thereby realizing the opening and closing control of the air extraction port.

[0028] Optionally, in some embodiments, the anti-fouling plate 3 is integrally formed, and the cross-section of the anti-fouling plate 3 corresponds to the cross-section of the mounting frame 1. The integrally formed structure avoids splicing gaps, reduces the possibility of pollutants seeping into the mounting frame 1 and the inner wall of the air extraction port from the gaps, and the integral forming makes the anti-fouling plate 3 itself stronger and less likely to be damaged by airflow impact or slight collision during the coating operation.

[0029] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the anti-fouling plate 3 is provided in a split manner. The anti-fouling plate 3 includes a first anti-fouling plate 31 arranged in the horizontal direction and a second anti-fouling plate 32 arranged in the vertical direction. There are two first anti-fouling plates 31 and two second anti-fouling plates 32. The cross-section enclosed by the two first anti-fouling plates 31 and the two second anti-fouling plates 32 corresponds to the cross-section of the mounting frame 1.

[0030] like Figures 1 to 4The anti-fouling plate 3 shown includes a first anti-fouling plate 31 arranged in the horizontal direction and a second anti-fouling plate 32 arranged in the vertical direction. Both the first anti-fouling plate 31 and the second anti-fouling plate 32 are detachably connected to the mounting frame 1.

[0031] Furthermore, both the first anti-fouling plate 31 and the second anti-fouling plate 32 are detachably connected to the mounting frame 1. When a first anti-fouling plate 31 or a second anti-fouling plate 32 is damaged or needs cleaning, the user can disassemble it individually without dismantling the whole unit, which helps to reduce maintenance difficulty and cost.

[0032] Furthermore, compared to the large, one-piece molded anti-fouling panel 3, the split first anti-fouling panel 31 and the second anti-fouling panel 32 are smaller in size and lighter in weight, making them easier to transport and store, and helping to reduce the risk of damage from bumps during transportation.

[0033] Furthermore, the cross-section enclosed by the two first anti-fouling plates 31 and the two second anti-fouling plates 32 corresponds to the cross-section of the mounting frame 1, which helps to form a complete protective barrier, avoids blind spots in protection, and effectively ensures comprehensive anti-fouling of the mounting frame 1 and the inner wall of the exhaust port.

[0034] Optionally, the first anti-fouling plate 31 and the second anti-fouling plate 32 can be connected to the mounting frame 1 by means of threaded connection, snap-fit ​​connection, slot connection, etc.

[0035] like Figures 1 to 4 The first anti-fouling plate 31 shown includes a first connecting plate 311 arranged in the horizontal direction, and the first anti-fouling plate 31 is threadedly connected to the mounting frame 1 through the first connecting plate 311; the second anti-fouling plate 32 includes a second connecting plate 321 arranged in the vertical direction, and the second anti-fouling plate 32 is threadedly connected to the mounting frame 1 through the second connecting plate 321.

[0036] Furthermore, the first anti-fouling plate 31 is threadedly connected to the mounting frame 1 via the first connecting plate 311 and the second anti-fouling plate 32 via the second connecting plate 321. The threaded connection has high connection strength and self-locking properties, which can effectively resist external forces such as airflow impact during the coating operation, and prevent the first anti-fouling plate 31 and the second anti-fouling plate 32 from loosening or falling off, thus ensuring the stability of the anti-fouling structure.

[0037] Furthermore, threaded connection is a common and mature connection method. Users can easily complete the connection and disassembly of the first anti-fouling plate 31 and the second anti-fouling plate 32 with the mounting frame 1 using simple tools such as screwdrivers or wrenches. No complicated operating skills or professional equipment are required, which greatly shortens the installation and disassembly time and improves work efficiency.

[0038] Furthermore, the first anti-fouling plate 31 and the second anti-fouling plate 32 are fixed by the first connecting plate 311 and the second connecting plate 321 respectively, so that the user can install the plate in one direction first and then install the plate in the other direction. This facilitates a flexible assembly sequence and helps to adapt to the installation needs in narrow spaces or complex working conditions.

[0039] like Figures 1 to 4 The first anti-fouling plate 31 shown includes a first extension plate 312 arranged parallel to the first connecting plate 311, and the second anti-fouling plate 32 includes a second extension plate 322 arranged parallel to the second connecting plate 321. Both the first extension plate 312 and the second extension plate 322 extend toward the inside of the vacuum chamber of the coating machine and are located on the side close to the central axis of the mounting frame 1.

[0040] Furthermore, the first extension plate 312 and the second extension plate 322 extend toward the interior of the vacuum chamber and are located on the side close to the central axis of the mounting frame 1, which can more accurately block contaminants approaching the mounting frame 1 and the inner wall of the exhaust port, especially for contaminants that diffuse from the central area of ​​the vacuum chamber to the exhaust port, forming a more direct interception barrier and improving the effectiveness of anti-fouling.

[0041] Furthermore, the first extension plate 312 is parallel to the first connecting plate 311, and the second extension plate 322 is parallel to the second connecting plate 321, so that the overall structure of the anti-fouling plate 3 is more regular. The two first extension plates 312 and the two second extension plates 322 can form a continuous protective area around the central axis of the mounting frame 1, reducing anti-fouling dead corners.

[0042] Furthermore, since the first connecting plate 311 and the second connecting plate 321 typically have screw holes, solder joints or steps, they are prone to forming local electric field concentration or airflow vortex, which leads to preferential deposition of pollutants. The arrangement of the first extension plate 312 and the second extension plate 322, so that the first connecting plate 311 and the second connecting plate 321 are located on the "leeward side" or in a low particle flux area, is beneficial to reducing the risk of pollution.

[0043] like Figures 1 to 4 The first anti-fouling panel 31 shown includes a first transition panel 313, and the first extension panel 312 is connected to the first connecting panel 311 through the first transition panel 313; the second anti-fouling panel 32 includes a second transition panel 323, and the second extension panel 322 is connected to the second connecting panel 321 through the second transition panel 323.

[0044] Furthermore, the first transition plate 313 and the second transition plate 323 serve as connecting bridges between the first extension plate 312 and the first connecting plate 311, and between the second extension plate 322 and the second connecting plate 321, respectively. This effectively disperses the stress at the connection points, avoids localized stress concentration caused by the direct connection between the extension plate and the connecting plate, enhances the overall structural stability and deformation resistance of the first anti-fouling plate 31 and the second anti-fouling plate 32, and extends their service life.

[0045] Furthermore, the transition plate, as a connecting segment, can be offset in height or radial direction, so that the connecting plate and the extension plate are on different planes, thereby avoiding interference between the connecting structure and the shielding area.

[0046] Furthermore, by using transition plates to achieve stepped or inclined connections, a stepped sealing path can be formed between the first anti-fouling plate 31 and the second anti-fouling plate 32 and the mounting frame 1, reducing the possibility of pollutants directly penetrating into the inner wall of the exhaust port along the connection surface, which is beneficial to improving the integrity of protection.

[0047] like Figures 1 to 4 The first transition plate 313 shown is inclinedly connected to the first connecting plate 311 and the first extension plate 312 on both sides and has rounded corners; the second transition plate 323 is inclinedly connected to the second extension plate 322 and the second connecting plate 321 on both sides and has rounded corners.

[0048] Furthermore, the first transition plate 313 and the second transition plate 323 adopt an inclined connection method, which makes the force transmission between the connecting plate and the extension plate smoother. Combined with the rounded corner setting, it can completely eliminate the sharp angle stress concentration point at the connection part, greatly reducing the risk of fatigue damage caused by vibration, airflow impact, etc. during long-term use, which is conducive to significantly improving the overall structural strength and durability of the first anti-fouling plate 31 and the second anti-fouling plate 32.

[0049] Furthermore, the inclined transition plate can more naturally connect the connecting plate and the extension plate, reducing the gaps that may be caused by the right-angle connection; secondly, the rounded corners can prevent pollutants from accumulating in the corners, and at the same time prevent the tiny particles carried by the airflow from swirling around the protective area at the sharp corners, further improving the integrity and interception effect of the anti-pollution barrier.

[0050] Furthermore, the rounded corners eliminate sharp edges at the joints of the transition plates, preventing operators from being scratched during installation, maintenance, or replacement of the anti-fouling plates. This also reduces wear on other components, improving safety during equipment operation and maintenance.

[0051] like Figures 1 to 4The mounting part 2 shown includes a plurality of mounting through holes 21 arranged vertically at intervals on the mounting frame 1, and the second connecting plate 321 is provided with a clearance notch 3211 adapted to the mounting through holes 21;

[0052] Furthermore, the mounting through holes 21 of the mounting part 2 are spaced apart in the vertical direction, providing a position for the installation of the grating plate. The clearance notch 3211 on the second connecting plate 321 is adapted to the mounting through holes 21, so that the mounting through holes 21 can be avoided when the second anti-fouling plate 32 is installed, thus avoiding interference between the anti-fouling plate 3 and the mounting structure of the grating plate, and ensuring that the two can be installed independently and stably.

[0053] Furthermore, when installing the second anti-fouling plate 32, there is no need to adjust the position of the mounting through hole 21 or disassemble the mounting structure of the grating plate. The second anti-fouling plate 32 can be quickly aligned and installed simply by avoiding the notch 3211, which helps to reduce the complexity of the installation operation and effectively improve the assembly efficiency.

[0054] Furthermore, when the second anti-fouling plate 32 needs to be disassembled for cleaning or replacement, the avoidance notch 3211 allows it to be removed separately without removing the grating or other fasteners, which significantly improves the convenience of maintenance.

[0055] like Figures 1 to 4 The second anti-fouling plate 32 shown includes a shielding portion 324 that is perpendicularly connected to the second extension plate 322. The shielding portion 324 is located at the connection between the second extension plate 322 and the first extension plate 312, and the cross-section of the shielding portion 324 partially overlaps with the cross-section of the first extension plate 312.

[0056] Furthermore, the shielding part 324 is located at the connection between the second extension plate 322 and the first extension plate 312, and its cross-section partially overlaps with the cross-section of the first extension plate 312. This effectively covers any gaps or gaps that may exist between the two extension plates, preventing contaminants from bypassing the first anti-fouling plate 31 and the second anti-fouling plate 32 from this part and adhering to the mounting frame 1 or the inner wall of the air extraction port, thereby further improving the integrity of the anti-fouling barrier.

[0057] Furthermore, the shielding part 324 is vertically connected to the second extension plate 322 and overlaps with the cross-sectional portion of the first extension plate 312, so that the first anti-fouling plate 31 and the second anti-fouling plate 32 form a tighter fit, which is conducive to forming a multi-layer anti-fouling structure, enhancing the interception capability of pollutants diffused in different directions, and improving the overall anti-fouling effect.

[0058] Furthermore, during actual installation, there may be slight positional deviations or misalignments between the first anti-fouling plate 31 and the second anti-fouling plate 32. The cross-section of the shielding part 324 partially overlaps with the cross-section of the first extended plate 312, which can compensate for assembly errors within a certain range and ensure that even if the plates are not fully aligned, effective protective coverage can still be maintained, avoiding local contamination caused by gaps.

[0059] like Figures 1 to 4 The first anti-fouling panel 31 shown is integrally formed; the second anti-fouling panel 32 is integrally formed.

[0060] Furthermore, the first anti-fouling plate 31 and the second anti-fouling plate 32 are integrally formed, which avoids the weak connection points that may exist when splicing the components, can withstand greater airflow impact and external force, reduce the risk of deformation or damage, and extend service life.

[0061] Furthermore, the one-piece molding process allows for the complete fabrication of the overall structure of the first anti-fouling plate 31 and the second anti-fouling plate 32 in a single process, reducing the number of parts and assembly steps, minimizing errors during production and assembly, improving production efficiency and equipment consistency, and saving assembly time and costs.

[0062] Furthermore, the first anti-fouling plate 31 and the second anti-fouling plate 32 are integrally formed, with a stable structure that is not prone to local loosening or damage, reducing maintenance needs caused by component splicing issues; secondly, even if cleaning or replacement is required, the first anti-fouling plate 31 and the second anti-fouling plate 32 can be operated as a whole, simplifying the maintenance process.

[0063] like Figures 1 to 4 The coating machine shown includes a coating chamber housing and a grid plate mounting frame with an anti-fouling mechanism as described above, which is connected to the coating chamber housing.

[0064] Specifically, by connecting the mounting frame 1 with anti-fouling plate 3 to the coating chamber, contaminants such as splash particles generated during the coating process can be effectively shielded, preventing them from directly depositing on the mounting frame 1 and inner wall surface around the exhaust port. This significantly reduces the accumulation of contaminants in the exhaust channel and avoids a decrease in exhaust efficiency due to reduced flow area. At the same time, the anti-fouling plate 3 can effectively prevent contaminants from peeling off and entering the vacuum chamber after long-term operation and mixing into the coating layer, improving the uniformity of the coating and product yield. In addition, the mounting frame 1 integrates the detachable anti-fouling plate 3, which facilitates cleaning and maintenance, helps extend the equipment maintenance cycle, and effectively improves operational stability.

[0065] Optionally, the mounting frame 1 can be installed on the coating chamber housing by means of threaded connection, snap-fit ​​connection, slot connection, etc.

[0066] The implementation method of Example 1 is as follows:

[0067] A grid mounting frame with an anti-fouling mechanism includes a mounting frame 1 disposed at the air extraction port of a vacuum coating machine. The mounting frame 1 is provided with a mounting part 2 for mounting the grid and an anti-fouling plate 3 for preventing the mounting frame 1 and the inner wall of the air extraction port from being contaminated. The anti-fouling plate 3 is located on the side of the mounting frame 1 near the air extraction port and extends toward the interior of the vacuum chamber of the coating machine.

[0068] This invention, by installing an anti-fouling plate on the mounting frame, with the plate located on the side of the mounting frame near the air extraction port and extending towards the interior of the vacuum chamber of the coating machine, can prevent splashed coating materials or volatile impurities from directly adhering to the inner walls of the mounting frame and air extraction port. This significantly reduces the accumulation of contaminants in the air extraction port area and avoids the reduction of the air extraction port's flow area. It effectively solves the problem that existing coating machines often generate splashed coating materials or volatile impurities during the coating process. After long-term operation, these contaminants accumulate on the inner walls of the mounting frame and air extraction port, resulting in a reduction of the air extraction port's flow area, affecting air extraction efficiency, and making it easy for contaminants to fall off and mix into the coating layer during subsequent operations, affecting the coating quality.

[0082] Based on Embodiment 4, Embodiment 8 further includes the following implementation: The second anti-fouling plate 32 includes a shielding portion 324 that is perpendicularly connected to the second extension plate 322. The shielding portion 324 is located at the connection between the second extension plate 322 and the first extension plate 312, and the cross-section of the shielding portion 324 partially overlaps with the cross-section of the first extension plate 312.
