Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and more specifically to a high-speed roller deceleration mechanism. Background Technology
[0002] Highly oriented thin films refer to thin film materials with highly ordered molecular or crystal structures arranged in a specific direction.
[0003] This characteristic enables highly oriented thin films to have wide applications in fields such as optics, electronics, and magnetic materials, such as liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, and solar cells.
[0004] A spin coater is a device used to prepare highly oriented thin films. It uses a high-speed rotating roller to uniformly diffuse a solution dropped onto it, forming a thin and uniform film. It can be seen that the roller speed control is crucial; to ensure a high yield of finished films, the roller speed directly determines the high orientation performance of the film.
[0005] To address the aforementioned issues, existing spin coaters typically incorporate a gearbox between the drive unit and the roller. However, this gearbox is relatively large, resulting in the reduction section occupying excessive space and making the overall spin coater structure less compact. Utility Model Content
[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a high-speed roller deceleration mechanism that is compact in structure and can ensure that the roller can achieve a high orientation setting speed.
[0007] To achieve the above objectives, this utility model can be implemented through the following technical solutions:
[0008] A high-speed roller reduction mechanism is disclosed. A spin coater includes a frame, a roller, and a drive component. The roller is axially fixed to the frame, and the drive component is fixedly connected to the frame and connected to the roller. The high-speed roller reduction mechanism is located between the drive component and the roller, and includes an inner cover, an outer cover, a reinforcing connection assembly, and a reduction gear set. The inner cover has a hollow interior with an open inner end, and the outer cover also has a hollow interior with an open inner end. The ports of the inner and outer covers face each other, and the inner ends of the inner and outer covers are fixedly connected by the reinforcing connection assembly. After the inner and outer covers are fastened together, a gear cavity with a hollow interior is formed between them. The reduction gear set is connected within the gear cavity. The input end of the reduction gear set is used to connect to the drive component, and the output end of the reduction gear set is used to connect to the roller.
[0009] In the aforementioned high-speed roller deceleration mechanism, the reinforcing connection assembly includes a limiting ring, a sealing ring, and fasteners. The limiting ring is made of non-metallic material, with one end of the limiting ring embedded in the inner cover port and the other end embedded in the outer cover port. The fasteners are inserted and connected to the inner and outer covers, and the sealing ring is pressed tightly between the inner and outer covers. The inner side of the sealing ring abuts against the limiting ring.
[0010] In the aforementioned high-speed roller deceleration mechanism, the limiting ring is made of plastic.
[0011] In the aforementioned high-speed roller deceleration mechanism, the limiting ring is made of rubber.
[0012] In the aforementioned high-speed roller deceleration mechanism, the inner cover edge has several protruding connecting parts 1, and the outer cover edge has connecting parts 2 corresponding to the connecting parts 1 and 2. Fasteners are inserted and connected to the corresponding connecting parts 1 and 2.
[0013] In the aforementioned high-speed roller deceleration mechanism, when one end of the limiting ring abuts against the bottom of the inner cover, the length of the limiting ring extending out of the inner cover is A, and when the other end of the limiting ring abuts against the bottom of the outer cover, the length of the limiting ring extending out of the outer cover is B. The dimensions A and B are equal.
[0014] In the aforementioned high-speed roller deceleration mechanism, the inner cover and the outer cover have the same thickness.
[0015] In the aforementioned high-speed roller deceleration mechanism, the outer edge of the inner cover is flush with the outer edge of the inner cover.
[0016] In the aforementioned high-speed roller deceleration mechanism, when the inner port of the inner cover abuts against the outer port of the outer cover, the dimension between the bottom of the inner cover and the bottom of the outer cover is D, and the thickness of the limiting ring is E, wherein E is 1.05 to 1.15 times D.
[0017] Compared with the prior art, this high-speed roller reduction mechanism is thinner because the thickness of the inner cover is 1 / 6 to 1 / 4 of its width, and the thickness of the inner cover is the same as that of the outer cover. Therefore, the entire mechanism is thinner, occupies less space between the drive component and the roller, and its structure is simple and compact.
[0018] Meanwhile, because the deceleration mechanism occupies little space, the drive components can be placed as close as possible to the roller, avoiding excessive power loss during long-distance power transmission. Ultimately, this ensures that the roller can rotate at the set speed, thereby ensuring that the roller in the spin coater achieves a precise set speed. In other words, the uniform deceleration of this mechanism plays a very important role in achieving high orientation of the roller in the spin coater. Attached Figure Description

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0024] like Figure 1 and Figure 2 As shown, the spin coater includes a frame, a roller, and a drive unit. The roller is axially fixed on the frame, and the drive unit is fixed to the frame and connected to the roller.
[0025] This high-speed roller reduction mechanism is located between the drive component 1 and the roller, and includes an inner cover 2, an outer cover 3, a reinforcing connection assembly, and a reduction gear set 4. The inner cover 2 has a hollow interior with an open inner end, and the outer cover 3 has a hollow interior with an open inner end. The ports of the inner cover 2 and the outer cover 3 are arranged facing each other, and the inner ends of the inner cover 2 and the outer cover 3 are fixedly connected by the reinforcing connection assembly. After the inner cover 2 and the outer cover 3 are fastened together, a gear cavity with a hollow interior is formed between them. The reduction gear set 4 is connected in the gear cavity. The input end of the reduction gear set 4 is used to connect with the drive component 1, and the output end of the reduction gear set 4 is used to connect with the roller.
[0026] The thickness of the inner cover 2 is 1 / 6 to 1 / 4 of its width, and the thickness of the inner cover 2 is the same as that of the outer cover 3.
[0027] Therefore, the thickness of the entire reduction mechanism is relatively thin. The reduction gear set 4 is set inside the gear cavity, and the input end of the reduction gear set 4 is connected to the drive component 1, while the output end of the reduction gear set 4 is connected to the roller of the spin coater.
[0028] After the power output from drive component 1 is transmitted over a short distance through this reduction mechanism, the drum can rotate stably at a set speed.
[0029] In other words, because the distance between the drive component 1 and the roller is relatively short during the power transmission process, the loss during the power transmission process is minimized, and the roller can eventually rotate at the set speed.
[0030] In this embodiment, the reduction gear set 4 is existing technology and is a commercially available component. Therefore, the specific component composition of the reduction gear set 4 will not be described in detail in this embodiment.
[0031] The reinforcing connection assembly includes a limiting ring 7, a sealing ring 6, and fasteners. The limiting ring 7 is made of non-metallic material, and one end of the limiting ring 7 is embedded in the port of the inner cover 2, while the other end of the limiting ring 7 is embedded in the port of the outer cover 3. The fasteners are inserted and connected to the inner cover 2 and the outer cover 3, and the sealing ring 6 is pressed tightly between the inner cover 2 and the outer cover 3. The inner side of the sealing ring 6 abuts against the limiting ring 7.
[0032] The reinforced connection assembly ensures a stable snap-fit connection between the inner cover 2 and the outer cover 3, and guarantees a high degree of sealing at the connection point.
[0033] The sealing ring 6 is existing technology and is also a commercially available component. The flexible sealing ring 6 has its inner side abutting against the outer side of the limiting ring 7, ultimately ensuring that the sealing ring 6 is stably positioned between the inner cover 2 and the outer cover 3.
[0034] After the fasteners are installed on the inner cover 2 and the outer cover 3, the sealing ring 6 ensures that the connection has good sealing performance.
[0035] The limiting ring 7 is made of plastic. However, depending on the specific circumstances, it is also feasible to use rubber as the limiting ring 7.
[0036] The limiting ring 7 is made of a non-metallic flexible material. Therefore, the limiting ring 7 can deform appropriately when subjected to force, which makes the whole mechanism easy to install and remove.
[0037] The inner cover 2 has several protruding connecting parts 2a at its edge, and the outer cover 3 has connecting parts 3a corresponding to the connecting parts 2a at its edge. Fasteners are inserted and connected to the corresponding connecting parts 2a and connecting parts 3a.
[0038] Connecting part 1 2a and connecting part 2 3a provide sufficient space for fastener connection.
[0039] When one end of the limiting ring 7 abuts against the bottom of the inner cover 2, the length of the limiting ring 7 extending out of the inner cover 2 is A. When the other end of the limiting ring 7 abuts against the bottom of the outer cover 3, the length of the limiting ring 7 extending out of the outer cover 3 is B. The dimensions A and B are equal.
[0040] This structure allows the two ends of the limiting ring 7 to be stably embedded in the inner cover 2 and the outer cover 3.
[0041] The inner cover 2 and the outer cover 3 have the same thickness.
[0042] This simplifies assembly. During assembly, there is no need to distinguish between the inner cover 2 and the outer cover 3. That is, the inner cover 2 can be used as the inner cover 2, and the inner cover 2 can also be interchanged with the outer cover 3. After the interchange, the inner cover 2 can also be used as the outer cover 3.
[0043] The outer edge of the inner cover 2 is flush with the outer edge of the inner cover 3.
[0044] This improves the overall structural compactness of the mechanism.
[0045] When the inner port of the inner cover 2 abuts against the outer port of the outer cover 3, the dimension between the bottom of the inner cover 2 and the bottom of the outer cover 3 is D, and the thickness of the limiting ring 7 is E, where E is 1.05 to 1.15 times D.
[0046] It can be seen that the thickness of the limiting ring 7 is relatively large. After the inner cover 2 is connected to the outer cover 3, the two ends of the limiting ring 7 are squeezed. This not only further improves the sealing performance, but also appropriately avoids rigid contact between the inner cover 2 and the outer cover 3.
[0047] Because the thickness of the inner cover of this high-speed roller reduction mechanism is 1 / 6 to 1 / 4 of its width, and the thickness of the inner cover is the same as that of the outer cover, the entire mechanism is relatively thin. This mechanism occupies little space between the drive component and the roller, and its structure is simple and compact.
[0048] Meanwhile, because the deceleration mechanism occupies little space, the drive components can be placed as close as possible to the roller, avoiding excessive power loss during long-distance power transmission. Ultimately, this ensures that the roller can rotate at the set speed, thereby ensuring that the roller in the spin coater achieves a precise set speed. In other words, the uniform deceleration of this mechanism plays a very important role in achieving high orientation of the roller in the spin coater.
[0049] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
[0050] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
