Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum coating equipment, and in particular relates to a substrate frame and coating device. Background Technology

[0002] In the evaporation coating process, the substrate is typically first loaded onto a rotatable substrate holder with the substrate's surface to be coated facing the coating source, followed by vacuum coating. In existing technologies, the substrate holder is often designed as a coating umbrella structure with multiple substrate loading positions; each loading position has a cutout area to ensure that the substrate's surface to be coated can receive the coating material emitted from the coating source. However, conventional substrate holders are generally only suitable for loading substrates with a diameter of 0.5 meters or less and a weight not exceeding 100 kg. Using conventional substrate holders to load ultra-large and ultra-heavy substrates often presents technical problems such as difficult substrate installation and low equipment operational stability. Furthermore, the installation process mostly involves direct fixing, which cannot be disassembled, easily leading to interlocking issues. Utility Model Content

[0044] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0045] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0046] The substrate frame and coating apparatus provided in this embodiment are such that the substrate frame in this application is detachably snapped together by the first mounting seat and the second mounting seat of the second connecting part, thereby realizing the connection between the second substrate loading part and the processing chamber of the substrate. This not only enables the stable placement of heavy-duty substrates, but also allows the first mounting seat and the second mounting seat to be detached, thus reducing the likelihood of biting during assembly and disassembly. At the same time, the first connecting part connects the first substrate loading part and the second substrate loading part together, so that the space formed between the first substrate loading part, the first connecting part and the second substrate loading part can support and accommodate the substrate, enabling the stable placement of heavy-duty substrates. In addition, the first connecting part and the first substrate loading part are connected by a first mating position and a second mating position, which ensures stable connection while enabling detachable loading to meet different loading requirements.

[0047] like Figures 1 to 9 As shown, a substrate holder is provided for loading a substrate 1, including a first substrate loading part 2 for supporting the substrate 1; a second substrate loading part 3 disposed at a distance above the first substrate loading part 1; and a second connecting part 5 disposed on the side of the second substrate loading part 3 away from the first substrate loading part 2 for connecting the second substrate loading part 3 and the processing chamber of the substrate 1.

[0048] The second connecting part 5 includes a first mounting base 51 and a second mounting base 52. The first mounting base 52 is connected to the second substrate loading part 3. The second mounting base 52 is disposed at the end of the first mounting base 51 away from the second substrate loading part 3, and the end of the first mounting base 51 away from the second substrate loading part 3 is detachably snapped into the second mounting base 52.

[0049] For example, the end of the first mounting base 51 away from the second substrate loading part 3 is inserted into the interior of the second mounting base 52 and is detachably snapped into the interior of the second mounting base 52, thereby realizing the detachable connection between the first mounting base 51 and the second mounting base 52.

[0050] Furthermore, the first mounting base 51 has a first hollow region 511 inside, and the outer sidewall of the first mounting base 51 away from the second substrate loading part 3 has a plurality of first protrusions 512, and a first notch 513 is formed between adjacent first protrusions 512. The second mounting base 52 has a second hollow region 521 inside, and the inner sidewall of the second mounting base 52 near the second substrate loading part 3 has a plurality of second protrusions 522, and a second notch 523 is formed between adjacent second protrusions 522.

[0051] The first protrusion 512 and the second protrusion 522 are vertically corresponding to each other, and the first mounting base 51 and the second mounting base 52 are coaxially arranged. In the axial direction of the first mounting base 51 and the second mounting base 52, the cross-sectional area of ​​the first protrusion 512 is smaller than the cross-sectional area of ​​the second notch 523, and the relative mating surfaces of the first protrusion 512 and the second protrusion 522 are matched in shape.

[0052] In this embodiment, since the cross-sectional area of ​​the first protrusion 512 is smaller than the cross-sectional area of ​​the second notch 523, the first protrusion 512 is then placed directly below the second protrusion 522 by passing the first protrusion 512 through the second notch 523. This causes the first protrusion 512 at the bottom of the first mounting base 51 to be attached to the direct underside of the second protrusion 522 of the second mounting base 52, so that the first protrusion 512 and the second protrusion 522 are stacked together, thereby fixing the first mounting base 51 and the second mounting base 52 together.

[0053] Furthermore, the first notch 513 and the second notch 523 are vertically aligned and embedded with wedge blocks 53. A pressure ring 54 is provided above the wedge blocks 53. The pressure ring 54 is installed on the inner wall of the second mounting base 52. A detachable second fastener 55 is provided between the pressure ring 54 and the wedge blocks 53. The first protrusion 512 corresponds to the second protrusion 522, and the wedge blocks 53 are provided between the first notch 513 and the second notch 523. The wedge blocks 53 and the pressure ring 54 are fixed together by the second fastener 55, thereby achieving a stable connection between the first mounting base 51 and the second mounting base 52, so that the first mounting base 51 will not have relative displacement with the second mounting base 52, including radial displacement and axial displacement.

[0054] After the first mounting base 51 and the second mounting base 52 are stacked and attached together by multiple first protrusions 512 and second protrusions 522, wedge blocks 53 are installed at the positions of the first notch 513 and the second notch 523, and the pressure ring 54 and the wedge blocks 53 on the inner wall of the second mounting base 52 are fixed together by the second fastener 55. Thus, the wedge blocks 53 limit the first notch 513 and the second notch 523, so that the first mounting base 51 and the second mounting base 52 will not have radial displacement after fixed installation, thus ensuring the stability of the first mounting base 51 and the second mounting base 52 after installation.

[0055] In traditional substrate frame structures, the main body of the substrate frame used to support the substrate and its rotational transmission mechanism are usually fixed with screws to bear the load. However, this method is not suitable for heavy-duty substrates such as those weighing more than 1 ton, for the following reasons: First, screws are subject to load fatigue after use; if the threads are damaged, the main body of the substrate frame and the substrate may fall. Second, because the screw threads need to bear the load, they are prone to biting during later assembly and disassembly. In this application, after the first protrusion 512 and the second protrusion 522 are attached at an angle, a wedge block 53 is inserted into the first notch 513 and the second notch 523, and the wedge block 53 is fixed to the pressure ring 54 by the second fastener 55. This achieves a stable connection between the first mounting base 51 and the second mounting base 52, and facilitates disassembly. After installation, the first mounting base 51 and the second mounting base 52 will not experience radial displacement during the driving process, effectively solving the problems caused by the screw fixing in the prior art.

[0056] In some embodiments, the contact surfaces of the first protrusion 512 and the second protrusion 522 are inclined surfaces, which increases the contact area and makes it less likely for the first protrusion 512 and the second protrusion 522 to slip off. Moreover, it helps to maximize the contact area within the same space, reduce pressure, and facilitate the concentric fit of the components during assembly.

[0057] In some other embodiments, a lifting ring 57 for lifting assembly is also installed at the top of the first mounting base 51, so as to facilitate the lifting of the second connecting part 5 through the lifting ring 57.

[0058] In this application, the first mounting base 51 and the second mounting base 52 are assembled using a snap-fit ​​structure. By passing the first protrusion 512 of the first mounting base 51 through the second notch 523 of the second mounting base 52, and by adjusting the first mounting base 51, the first protrusion 512 of the first mounting base 51 and the second protrusion 522 of the second mounting base 52 are brought together, thereby fixing the first mounting base 51 and the second mounting base 52. This is further fixed with the wedge block 53, achieving a stable connection while allowing for easy disassembly. This structure allows for adjustable clamping of substrates of various diameters. Moreover, the inclined placement of the first protrusion 512 and the second protrusion 522 is beneficial for maximizing the contact area within the same space, reducing pressure, and improving the concentricity of component assembly.

[0059] In some other embodiments, the substrate frame further includes a first connecting portion 4, which is installed between the first substrate loading portion 2 and the second substrate loading portion 3 to connect the first substrate loading portion 2 and the second substrate loading portion 3. The space formed between the first connecting portion 4, the first substrate loading portion 2 and the second substrate loading portion 3 is used to accommodate the substrate 1.

[0060] Further, the first substrate loading portion 2 includes a first opening 21 and a first edge 22. The first opening 21 is disposed inside the first edge 22 and is used to expose the surface of the substrate 1 to be processed. The surface of the first edge 22 is provided with at least one first mating position. The first connecting portion 4 is provided with at least one second mating position at one end near the first substrate loading portion 2. The first connecting portion 4 and the first substrate loading portion 2 are connected through the mating of the first mating position and the second mating position. The space formed by the first substrate loading portion 2, the second substrate loading portion 3, and the first connecting portion 4 is used to accommodate the substrate 1. The first connecting portion 4 is provided with at least one third mating position at one end away from the first substrate loading portion 2. The second substrate loading portion 3 is provided with at least one fourth mating position 31 along the circumferential direction. The end of the first connecting portion 4 away from the first substrate loading portion 2 and the second substrate loading portion 3 are connected in a detachable manner through the mating of the third and fourth mating positions.

[0061] In this embodiment, one end of the first substrate loading part 2 and the first connecting part 4 are fixedly connected together by a first mating position and a second mating position. The other end of the first connecting part 4 is detachably connected to the second substrate loading part 3 by a third mating position and a fourth mating position. Thus, the first substrate loading part 2 and the second substrate loading part 3 are connected together by the first connecting part 4, and the space formed between the first substrate loading part 2, the second substrate loading part 3, and the first connecting part 4 is used to accommodate and place the substrate 1. The first opening 21 on the first substrate loading part 2 exposes the surface of the substrate 1 to be processed, facilitating processing of the substrate 1. The entire structure uses a detachable connection. Compared with the screw fixing in the prior art, the fixing method of this application is more stable and less prone to biting during disassembly and assembly.

[0062] It should be noted that the first opening 21 can be hollow or notched, and the first edge 22 can be a closed ring or a ring with a notch. This solution does not impose any special restrictions on this, and will not be elaborated here.

[0063] In some embodiments, one of the corresponding first mating position and the second mating position is provided with a second opening 23, and the other of the corresponding first mating position and the second mating position is provided with a first hook member 42. The second opening 23 includes a communicating second opening insertion area 231 and a second opening hook area 232. The first hook member 42 is provided with a second opening hook position 422 and a second opening insertion position 421 along the direction from the first substrate loading part 2 to the second substrate loading part 3. The second opening hook position 422 passes through the second opening insertion area 231 and enters the second opening hook area 232, so that the second opening hook position 422 matches the edge of the second opening hook area 232 to achieve a detachable connection.

[0064] In this solution, one end of the first connecting part 4 and the first substrate loading part 2 are connected through a first opening 23 and a first hook 42 that match each other. While ensuring the support of the substrate, it is easy to realize the detachable connection between the first connecting part 4 and the first substrate loading part 2, making it more convenient to use and meeting different installation requirements.

[0065] It should be noted that the second opening 23 can be hollow or notched. The edge of the second opening 23 can be a closed ring or a ring with a notch. This solution does not impose any special restrictions on this, and will not be elaborated here.

[0066] Furthermore, the second opening 23 is disposed on the first mating position, the first hook member 42 is disposed on the second mating position, the second opening insertion area 231 and the second opening hook area 232 are interconnected, and the interconnected second opening insertion area 231 and the second opening hook area 232 are distributed circumferentially along the first substrate loading part 2 to achieve rotational hooking, and the diameter of the second opening insertion area 231 is larger than the diameter of the second opening hook area 232.

[0067] The first mounting member 42 includes a first limiting frustum 423, a second opening mounting position 421 and a second opening insertion position 422, which are sequentially arranged on the first limiting frustum 423 along the direction from the first substrate loading part 2 to the second substrate loading part 3. The first limiting frustum 423 is located at one end of the first connecting part 4 near the first substrate loading part 2. The diameter of the side of the first limiting frustum 423 away from the first connecting part 4 is larger than the diameter of the connection between the first limiting frustum 423 and the first connecting part 4.

[0068] The second opening hook position 422 matches the second opening hook area 232. The first limiting frustum 423 passes through the second opening penetration area 231 and enters the second opening hook area 232, so that the second opening hook position 422 matches the edge of the second opening hook area 232 to achieve a detachable connection.

[0069] Specifically, when it is necessary to fix one end of the first connecting part 4 to the first substrate loading part 2, the first limiting frustum 423 of the first hook member 42 is inserted into the second opening 23. The first limiting frustum 423 first passes through the second opening insertion area 231 and then enters the second opening hook area 232, and matches the edge of the second opening hook area 232, thereby connecting the first limiting frustum 423 at the end of the first connecting part 4 to the first substrate loading part 2. Since the connection is achieved by matching the first limiting frustum 423 and the second opening hook area 232, it is convenient to disassemble.

[0070] In some other embodiments, the first mating position and the second mating position are both uniformly arranged along the circumference of the first substrate loading portion 2, so as to match the first opening 21 on the first substrate loading portion 2, so as to facilitate the exposure of the substrate 1 for processing, and at the same time facilitate the rotational hanging installation.

[0071] The first connecting part 4 is provided with at least one third mating position at one end away from the first substrate loading part 2, and the second substrate loading part 3 is provided with at least one fourth mating position along the circumferential direction on its surface. The first connecting part 4 is provided with at least one third mating position at one end away from the first substrate loading part 2, and the second substrate loading part 3 are connected to each other by the mating between the third mating position and the fourth mating position to form a detachable connection.

[0072] Furthermore, one of the corresponding third and fourth docking positions is provided with a third opening 31, and the other of the corresponding third and fourth docking positions is provided with a second hook member 41. The third opening 31 includes a connected third opening insertion area 311 and a third opening hook area 312. The second hook member 41 is provided with a third opening hook position 412 and a third opening insertion position 411 along the direction from the second substrate loading part 3 to the first substrate loading part 2.

[0073] The third opening hook position 412 passes through the third opening insertion area 311 and enters the third opening hook area 312, so that the edge of the third opening hook position 412 matches the edge of the third opening hook area 312 to achieve a detachable connection.

[0074] In this embodiment, the connection between the second substrate loading part 3 and the end of the first connecting part 4 is achieved by matching the corresponding third and fourth docking positions with the third opening 31 and the second hook 41, respectively. Since the third opening 31 and the second hook 41 are detachably connected, the first connecting part 4 and the second substrate loading part 3 can be detachably connected to achieve the detachable loading of the substrate 1.

[0075] Furthermore, the third opening 31 is disposed on the fourth mating position, the second hook member 41 is disposed on the third mating position, the third opening penetration area 311 and the third opening hook area 312 are interconnected, and the interconnected third opening penetration area 311 and the third opening hook area 312 are distributed circumferentially along the second substrate loading part 3, and the diameter of the third opening penetration area 311 is larger than the diameter of the third opening hook area 312.

[0076] The second connector 41 includes a second limiting frustum 413, a third opening connector 412 and a third opening insertion position 411, which are sequentially arranged on the second limiting frustum 413 along the direction from the second substrate loading part 3 to the first substrate loading part 2. The second limiting frustum 413 is located at the end of the first connecting part 4 away from the first substrate loading part 2. The diameter of the side of the second limiting frustum 413 away from the first connecting part 4 is larger than the diameter of the connection between the second limiting frustum 413 and the first connecting part 4.

[0077] The third opening hook position 412 matches the third opening hook area 312. The second limiting truncated cone 413 passes through the third opening insertion area 311 and enters the third opening hook area 312 so that the edge of the third opening hook position 412 matches the edge of the third opening hook area 312 to achieve detachable hooking.

[0078] Since the connection method between the other end of the first connecting part 4 and the second substrate loading part 3 is similar to the connection method between one end of the first connecting part 4 and the first substrate loading part 2 described above, it will not be repeated here.

[0079] In some embodiments, the third and fourth mating positions are evenly arranged along the circumference of the second substrate loading portion 3. This facilitates a rotary connection between the first connecting portion 4 and the second substrate loading portion 3.

[0080] In some other embodiments, the second substrate loading portion 3 is circumferentially concentrically provided with multiple sets of third opening hook areas 312 and at least one set of third opening insertion areas 311. The multiple sets of third opening hook areas 312 are arranged radially along the second substrate loading portion 3, and the third opening hook areas 312 arranged radially along the second substrate loading portion 3 are connected to the third opening insertion areas 311.

[0081] In this embodiment, by providing multiple sets of third opening hook areas 312, it is convenient to match substrates of different diameters through multiple sets of third opening hook areas 312, thereby increasing versatility. Correspondingly, different second hook members 41 are used to match the third opening hook areas 312 to achieve the support of substrates of different diameters. Moreover, the multiple sets of third opening hook areas 312 are arranged radially along the second substrate loading part 3, which facilitates the selection of the third opening hook area 312 that matches the third opening hook position 412 of the second limiting frustum 413 of the second hook member 41 after the second hook member 41 enters through the third opening insertion area 311, so as to quickly realize the installation of the first connecting part 4 and the second substrate loading part 3.

[0082] In some embodiments, a fourth opening 32 is provided at the middle position of the second substrate loading portion 3, and a flange 56 is provided at one end of the second connecting portion 5 near the second substrate loading portion 3. The flange 56 is circumferentially distributed and extends radially outward along the second substrate loading portion 3. The upper surface of the flange 56 is detachably overlapped with the lower surface of the peripheral area of ​​the fourth opening 32.

[0083] In some embodiments, a cover plate 34 is provided on the side of the second substrate loading portion 3 near the second connecting portion 5. The second connecting portion 5 and the cover plate 34 form an overlapping area on the side of the flange 56 near the fourth opening 32. A hole is provided through the overlapping area, and a detachable first fastener 35 is installed in the hole to connect the second connecting portion 5 and the second substrate loading portion 3 together.

[0084] Furthermore, a chassis 33 is provided on the side of the second substrate loading portion 3 away from the second connecting portion 5. The second connecting portion 5, the chassis 33 and the cover plate 34 form an overlapping area on the side of the flange 56 near the fourth opening 32. A hole is provided through the overlapping area, and a detachable first fastener 35 is installed in the hole to connect the second connecting portion 5 and the second substrate loading portion 3 together.

[0085] Specifically, by placing the bottom of the second connecting part 5 in the space between the cover plate 34 and the chassis 33 arranged vertically on the second substrate loading part 3, and installing a detachable first fastener 35 inside the hole in the overlapping area of ​​the second connecting part 5, the cover plate 34, and the chassis 33, the second connecting part 5 and the second substrate loading part 3 can be stably connected together, while also achieving detachability. In addition, since the upper surface of the flange 56 and the lower surface of the area surrounding the fourth opening 32 form a detachable overlap area, the weight of the substrate 1, the first substrate loading part 2, and the second substrate loading part 3 mainly acts on the aforementioned overlap area, further enabling the first fastener 35 to mainly undertake a positioning function rather than a load-bearing function, effectively suppressing the biting phenomenon during assembly and disassembly, and improving the stability of substrate loading and equipment operation.

[0086] In some other embodiments, the second connecting part 5 further includes a bearing housing mounted on the top of the second mounting base 52. The bearing housing is connected to the drive shaft via a first gear set, and the drive shaft is connected to the power source via a second gear set.

[0087] This invention also provides a coating apparatus, including a coating source and the aforementioned substrate holder, which is used to fix the substrate during coating. Fixing the substrate with the substrate holder ensures stability during coating. Since the working principle of the substrate holder has been described above, it will not be repeated here.

[0088] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
