Description

Technical Field

[0001] This application relates to the field of evaporation coating technology, specifically to baffle mechanisms and coating machines. Background Technology

[0002] In the field of evaporative coating, a heating mechanism heats the metal to a certain temperature, generating metal vapor which then coats the substrate. The temperature during metal evaporation is extremely high, making it impossible to cool down quickly and stop evaporation. Therefore, when shutting down, a baffle must be placed between the substrate and the heating mechanism to prevent damage to the substrate.

[0003] Vacuum coating machines typically use evaporation baffles, which are usually made of high-temperature resistant metals (such as molybdenum and titanium) or ceramic materials, and are installed between the heating mechanism and the substrate. The evaporation baffles can be opened and closed quickly, allowing or blocking the passage of metal vapor, thereby allowing or blocking the metal vapor from being deposited onto the substrate.

[0004] In related technologies, the two ends of the evaporation baffle are rotatably connected to the two ends of the intermediate shaft through connectors. The substrate is installed in the middle of the intermediate shaft. The evaporation baffle rotates around the intermediate shaft as its center, and the distance between the evaporation baffle and the intermediate shaft is relatively large, resulting in a large rotation radius of the evaporation baffle. The drive mechanism is installed on the intermediate shaft, and the drive mechanism drives the connector to rotate, thereby causing the evaporation baffle to rotate. However, the temperature of the intermediate shaft is high, and the connector is prone to deformation due to heat. The connector and the intermediate shaft are prone to jamming, causing the evaporation baffle to jam. Utility Model Content

[0005] In view of this, this application provides a baffle mechanism and a coating machine to solve or improve the problem of jamming when the evaporation baffle moves.

[0006] In a first aspect, this application provides a baffle mechanism, comprising:

[0007] A coating tank has a through hole at the bottom for metal vapor to pass through. The coating tank is provided with a first tank wall and a second tank wall arranged opposite to each other. At least one of the first tank wall and the second tank wall is provided with a guide portion.

[0008] A baffle is slidably connected to the guide portion via a sliding connector. The baffle is adapted to slide between a blocking position and a clearance position. In the blocking position, the baffle blocks the through hole. In the clearance position, the baffle is away from the through hole.

[0009] The drive mechanism drives the baffle to slide via a transmission component.

[0010] In this embodiment, a through hole is provided at the bottom of the coating tank. The substrate is placed inside the coating tank, and a heating mechanism is provided below the coating tank. The heating mechanism heats the metal, and after heating to a certain temperature, metal vapor is generated. A baffle moves away from the through hole, and the metal vapor passes through the through hole to coat the substrate. When the coating is completed or stopped, the drive end of the drive mechanism is connected to the baffle through a transmission component, driving the baffle to move along the guide trajectory of the guide part, thereby blocking the through hole. The drive end of the drive mechanism directly drives the baffle to move through the transmission component. The baffle is connected to the first or second side wall of the coating tank through a sliding connector, and does not need to be connected to an intermediate shaft, which can avoid the problem of jamming when the baffle rotates due to structural deformation caused by temperature.

[0011] In one alternative embodiment, the sliding connector includes:

[0012] A sliding part is mounted on the baffle and slidably connected to the guide part, and the sliding surface of the sliding part is parallel to the first groove wall.

Each mounting block has a first connecting surface and a second connecting surface. The sliding part is disposed on the first connecting surface and the limiting part is disposed on the second connecting surface.

[0017] The first connecting surface is parallel to the plane containing the first groove wall.

[0018] In one alternative embodiment, the sliding connector further includes an adjustment component adapted to connect the mounting block and the baffle, the adjustment component being capable of adjusting the distance between the baffle and the bottom of the coating tank.

[0021] Two locking components are provided, and each of the two mounting blocks is provided with a connecting hole. The connecting hole can be arranged to correspond to any of the adjustment holes. The locking components are adapted to lock the connecting hole and the adjustment hole respectively.

[0022] Wherein, the second direction is the direction in which the baffle is away from the coating tank.

[0023] In one optional embodiment, the sliding part is a sliding wheel, which is rotatably connected to the first connecting surface of the mounting block, and the rotating surface of the sliding wheel is parallel to the first groove wall;

[0024] The limiting part is a limiting wheel. The two limiting wheels are rotatably connected to the second connecting surfaces of the two mounting blocks respectively. The two sets of limiting wheels roll against the first groove wall and the second groove wall respectively to prevent the sliding wheel from moving in the first direction.

[0025] In one optional embodiment, the bottom of the coating tank is an arc-shaped surface, and the guide trajectory of the guide part is the same as the arc-shaped trajectory of the bottom of the coating tank.

[0026] The transmission assembly includes:

[0027] A transmission plate, one side of which is connected to the side of the baffle away from the coating tank, the side of the transmission plate away from the baffle is configured as a transmission surface, and the transmission surface is adapted to the guide trajectory of the guide part;

[0028] An arc-shaped rack is mounted on the transmission surface, and the driving end of the driving mechanism is connected to the arc-shaped rack in a transmission connection.

[0029] In one optional embodiment, along a third direction, the distance between the arc-shaped rack and the bottom of the coating tank is greater than the distance between the baffle and the bottom of the coating tank;

[0030] Wherein, the third direction is the direction in which the baffle moves away from the coating tank.

[0031] Secondly, this application also provides a coating machine, comprising:

[0032] A baffle mechanism and a heating mechanism are provided, with the heating mechanism arranged corresponding to the through hole. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In the field of evaporative coating, a heating mechanism heats the metal to a certain temperature, generating metal vapor which then coats the substrate. The temperature during metal evaporation is extremely high, making it impossible to cool down quickly and stop evaporation. Therefore, when shutting down, a baffle must be placed between the substrate and the heating mechanism to prevent damage to the substrate.

[0043] Vacuum coating machines typically use evaporation baffles, which are usually made of high-temperature resistant metals (such as molybdenum and titanium) or ceramic materials, and are installed between the heating mechanism and the substrate. The evaporation baffles can be opened and closed quickly, allowing or blocking the passage of metal vapor, thereby allowing or blocking the metal vapor from being deposited onto the substrate.

[0044] In related technologies, the two ends of an evaporation baffle are rotatably connected to the two ends of an intermediate shaft via connectors. A substrate is installed in the middle of the intermediate shaft. The evaporation baffle rotates around the intermediate shaft, and the distance between the evaporation baffle and the intermediate shaft is relatively large, resulting in a large rotation radius. A drive mechanism is mounted on the intermediate shaft, which drives the connectors to rotate, thereby causing the evaporation baffle to rotate. However, the intermediate shaft has a high temperature, and the connectors are prone to deformation due to heat, which can easily cause jamming between the connectors and the intermediate shaft, leading to jamming of the evaporation baffle. To address this, this application provides a baffle mechanism and a coating machine to solve or improve the problem of jamming during the movement of the evaporation baffle.

[0045] The following is combined Figures 1 to 3 This describes an embodiment of the present application.

[0046] According to an embodiment of this application, in one aspect, a baffle mechanism is provided, including: a coating tank 1, a baffle 3, and a driving mechanism 5.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the bottom of the coating tank 1 is provided with a through hole 101 for metal vapor to pass through. The coating tank 1 is provided with a first tank wall 102 and a second tank wall 103 arranged opposite to each other. At least one of the first tank wall 102 and the second tank wall 103 is provided with a guide part 2.

[0048] The baffle 3 is slidably connected to the guide part 2 via the sliding connector 4. The baffle 3 is adapted to slide between the blocking position and the avoidance position. In the blocking position, the baffle 3 blocks the through hole 101. In the avoidance position, the baffle 3 is far away from the through hole 101.

[0049] The drive end of the drive mechanism 5 drives the baffle 3 to slide through the transmission component 6.

[0050] In this embodiment, such as Figure 1 and Figure 2 As shown, a through hole 101 is provided at the bottom of the coating tank 1. The substrate is placed in the coating tank 1. A heating mechanism is provided below the coating tank 1. The heating mechanism heats the metal, and after heating to a certain temperature, metal vapor is generated. The baffle 3 moves away from the through hole 101. The metal vapor passes through the through hole 101 and is coated on the substrate. When the coating is completed or when the coating is stopped, the driving end of the driving mechanism 5 is connected to the baffle 3 through the transmission component 6. The driving baffle 3 moves along the guide trajectory of the guide part 2, thereby blocking the through hole 101. The driving end of the driving mechanism 5 directly drives the baffle 3 to move through the transmission component 6. The baffle 3 is connected to the first or second side wall of the coating tank 1 through a sliding connector 4. It does not need to be connected to the intermediate shaft, which can avoid the structural deformation of the connector caused by temperature, which could cause the baffle 3 to jam when rotating.

[0051] In one embodiment, such as Figure 1 and Figure 3 As shown, the sliding connector 4 includes a sliding part 401, which is mounted on the baffle 3 and is slidably connected to the guide part 2. The sliding surface of the sliding part 401 is parallel to the first groove wall 102.

[0052] In this embodiment, such as Figure 1 and Figure 3 As shown, the sliding surface of the sliding part 401 is parallel to the first groove wall 102, which can ensure that when the sliding part 401 slides on the guide part 2, the distance between it and the first groove wall 102 remains unchanged in the direction perpendicular to the first groove wall 102, preventing the baffle 3 from moving in the direction perpendicular to the first groove wall 102, improving the stability of the sliding of the baffle 3, and improving the accuracy of the baffle 3 in blocking the through hole 101.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two guide parts 2, which are respectively disposed on the first groove wall 102 and the second groove wall 103, and two sliding parts 401 are disposed and respectively slidably connected to the two guide parts 2.

[0054] In one embodiment, such as Figure 1 and Figure 3As shown, the sliding connector 4 also includes two limiting parts 402, both of which are connected to the baffle 3. The two limiting parts 402 slide against the first groove wall 102 and the second groove wall 103 respectively to prevent the sliding part 401 from moving along the first direction X. The first direction X is the direction of the line connecting the first groove wall 102 and the second groove wall 103.

[0055] In this embodiment, such as Figure 1 and Figure 3 As shown, the two limiting parts 402 slide against the side opposite to the first groove wall 102 and the second groove wall 103, respectively, which can restrict the sliding part 401 from moving along the first direction X and can only slide along the direction parallel to the first groove wall 102, thereby improving the stability of the sliding of the baffle 3.

[0056] Specifically, the first tank wall 102 and the second tank wall 103 are arranged in parallel.

[0057] In some embodiments, such as Figure 1 and Figure 3 As shown, the guide part 2 is a guide hole, which is provided on the first groove wall 102. The guide hole can penetrate the first groove wall 102 along the first direction X, or it can be a blind hole. The sliding part 401 is slidably connected to the hole wall of the guide hole.

[0058] In some embodiments, the guide portion 2 may be a track, which is mounted on the first groove wall 102 and the guiding direction of the track is parallel to the first groove wall 102.

[0059] In one embodiment, such as Figure 1 and Figure 3 As shown, the sliding connector 4 further includes two mounting blocks 403, which are respectively connected to both ends of the baffle 3 and correspond to the first groove wall 102 and the second groove wall 103. Each mounting block 403 has a first connecting surface and a second connecting surface. The sliding part 401 is disposed on the first connecting surface, and the limiting part 402 is disposed on the second connecting surface. The first connecting surface is parallel to the plane where the first groove wall 102 is located.

[0060] In this embodiment, such as Figure 1 and Figure 3 As shown, the sliding part 401 is disposed on the first connecting surface of the mounting block 403. The first connecting surface is parallel to the first groove wall, which can ensure that the sliding surface of the sliding part 401 is parallel to the first groove wall 102. The limiting part 402 is disposed on the second connecting surface. The limiting part 402 is far away from the sliding part 401, which ensures that the limiting part 402 and the sliding part 401 do not affect each other.

[0061] In one embodiment, such as Figure 1 and Figure 3As shown, the sliding connector 4 also includes an adjustment component 404, which is adapted to connect the mounting block 403 and the baffle 3. The adjustment component 404 can adjust the distance between the baffle 3 and the bottom of the coating tank 1.

[0062] In this embodiment, adjusting the distance between the baffle 3 and the bottom of the coating tank 1, that is, adjusting the distance between the baffle 3 and the through hole 101, can control the baffle 3 to block the heat of metal vapor dissipating to the through hole 101. The closer the baffle 3 is to the through hole 101, the better the seal of the through hole 101, and the better the heat dissipated by the metal vapor passing through the through hole 101, and vice versa.

[0063] In one embodiment, the adjustment assembly 404 includes two adjustment plates 4041 and two locking members.

[0064] Specifically, such as Figure 1 and Figure 3 As shown, one side of each of the two adjusting plates 4041 is connected to one of the two mounting blocks 403, and the other side is connected to the baffle 3. Multiple adjusting holes 40411 are arranged along the second direction Y. Each of the two mounting blocks 403 is provided with a connecting hole, which can be arranged to correspond with any adjusting hole 40411. The locking component is suitable for locking the connecting hole and the adjusting hole 40411. The second direction Y is the direction in which the baffle 3 is away from the coating tank 1.

[0065] In this embodiment, after determining the distance between the baffle 3 and the coating tank 1, one of the adjustment holes 40411 on the adjustment plate 4041 is aligned with the connection hole on the mounting block 403. The locking member is then passed through the adjustment hole 40411 and the connection hole in sequence to connect the adjustment plate 4041 and the mounting block 403, thereby adjusting the distance between the baffle 3 and the coating tank 1. This results in a simpler structure and facilitates the maintenance and replacement of parts.

[0066] Specifically, the locking component can be a pin, screw, or connecting rod.

[0067] In some embodiments, such as Figure 3 As shown, it also includes two connecting plates 405. One side of each connecting plate 405 is connected to the baffle 3. The connecting plate 405 is provided with mounting holes, which can correspond to any one of the adjustment holes 40411. The adjustment plate 4041 is connected to the mounting block 403. By adjusting the correspondence between the mounting hole and the adjustment hole 40411 and connecting them through the pin, the distance between the baffle 3 and the coating tank 1 can be adjusted.

[0068] In some embodiments, such as Figure 3As shown, the adjusting assembly 404 also includes a connecting block 406 and a bolt 407. The connecting block 406 is connected to the connecting plate 405. The connecting block 406 is arranged below the adjusting plate 4041 along the second direction Y. The adjusting plate 4041 has a threaded hole. The connecting block 406 has a through hole corresponding to the threaded hole. The bolt 407 passes through the through hole and connects to the threaded hole. The adjusting bolt 407 can adjust the distance between the connecting block 406 and the adjusting plate 4041, thereby adjusting the distance between the baffle 3 and the coating tank 1.

[0069] In one embodiment, such as Figure 3 As shown, the sliding part 401 is a sliding wheel, which is rotatably connected to the first connecting surface of the mounting block 403. The rotating surface of the sliding wheel is parallel to the first groove wall 102.

[0070] The limiting part 402 is a limiting wheel. The two limiting wheels are rotatably connected to the second connecting surfaces of the two mounting blocks 403 respectively. The two sets of limiting wheels roll against the first groove wall 102 and the second groove wall 103 respectively to prevent the sliding wheel from moving along the first direction X.

[0071] In some embodiments, such as Figure 3 As shown, the sliding wheel is rotatably connected to the first connecting surface via the first connecting shaft. The first connecting shaft is perpendicular to the first groove wall 102, and the sliding wheel rolls against the wall of the guide hole. Both limiting wheels are rotatably connected to the second connecting surface via the second connecting shaft. The two limiting wheels roll against the first groove wall 102 and the second groove wall 103 respectively to prevent the sliding wheel from disengaging from the guide hole.

[0072] In one embodiment, such as Figure 1 and Figure 3 As shown, the bottom of the coating tank 1 is an arc-shaped surface, and the guide trajectory of the guide part 2 is the same as the arc-shaped trajectory of the bottom of the coating tank 1.

[0073] The transmission assembly 6 includes a transmission plate 601 and an arc-shaped rack 602.

[0074] Specifically, one side of the transmission plate 601 is connected to the side of the baffle 3 away from the coating tank 1, and the side of the transmission plate 601 away from the baffle 3 is set as the transmission surface, which is adapted to the guide trajectory of the guide part 2; the arc-shaped rack 602 is installed on the transmission surface, and the drive end of the drive mechanism 5 is connected to the arc-shaped rack 602.

[0075] In one embodiment, along a third direction, the distance between the arc-shaped rack 602 and the bottom of the coating tank 1 is greater than the distance between the baffle 3 and the bottom of the coating tank 1; wherein, the third direction is the direction in which the baffle 3 moves away from the coating tank 1.

[0076] Specifically, the third direction is the same as the second direction Y.

[0077] In some embodiments, such as Figure 1 As shown, the drive end of the drive mechanism 5 is connected to the arc-shaped rack 602, and drives the baffle 3 to move along the guide trajectory through the transmission plate 601, switching the baffle 3 between the blocking position and the avoidance position. The distance between the arc-shaped rack 602 and the bottom of the coating tank 1 is greater than the distance between the baffle 3 and the bottom of the coating tank 1. Therefore, when the arc-shaped rack 602 and the baffle 3 rotate at the same angle, the distance the baffle 3 rotates is less than the distance the arc-shaped rack 602 rotates, which can improve the rotation accuracy of the baffle 3 and increase the torque of the drive mechanism 5, making it easier to drive the baffle 3 to move.

[0078] Specifically, such as Figure 1 As shown, the drive mechanism 5 is a drive motor, and a gear 7 is mounted on the output shaft of the drive motor. The gear 7 is connected to the arc-shaped rack 602 for transmission.

[0079] According to an embodiment of this application, another aspect provides a coating machine, including a baffle mechanism and a heating mechanism, wherein the heating mechanism is arranged corresponding to the through hole 101.

[0080] Heating mechanisms are used to heat metal into metal vapor.

[0081] Specifically, the coating machine includes the baffle mechanism described above.

[0082] It should be noted that the coating machine includes the baffle mechanism provided in the embodiments of this application, and therefore includes all the advantages of the baffle mechanism mentioned above, so it will not be described again.

[0083] The following is an example, combined with Figures 1 to 3 A comprehensive explanation of all the above-mentioned plans is provided.

[0084] The heating device corresponds to the through hole 101 and is located at the bottom of the baffle 3. The two ends of the intermediate shaft are connected to the first tank wall 102 and the second tank wall 103, and the substrate is mounted on the intermediate shaft. Adjusting bolts 407 adjust the distance between the first and second adjusting blocks, thereby adjusting the distance between the baffle 3 and the coating tank 1. The heating mechanism heats the metal to form metal vapor. The drive motor drives the arc-shaped rack 602 to rotate via gear 7. The transmission plate 601 moves the baffle 3 to a clearance position, allowing the metal vapor to pass through the through hole 101 and coat the substrate. The drive motor can also adjust the amount of metal vapor passing through by changing the size of the baffle 3 blocking the through hole 101. When coating needs to be stopped, the drive motor drives the baffle 3 to the blocking position, sealing the through hole 101 and preventing heat and metal vapor from entering the coating tank 1 through the through hole 101.

[0085] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
