Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment technology, and in particular to a dustproof mobile workbench. Background Technology

[0002] In the pharmaceutical industry, there is a need for a mechanism that allows workpieces to move freely in two directions within a horizontal plane. Furthermore, this mechanism must minimize friction during movement in a clean environment, thereby reducing particle generation. Such a mechanism is crucial for precise positioning and operation in pharmaceutical manufacturing processes.

[0003] However, existing mechanisms have some significant drawbacks. First, the directional drive motor is typically installed in a clean environment, which exposes the motor cables to the clean environment as well. During the mechanism's movement, these cables inevitably rub against other parts, especially the mounting platform, generating a large amount of particles. The generation of these particles seriously affects the maintenance of the clean environment and may adversely impact the quality of pharmaceutical production.

[0004] Secondly, all connections between clean and non-clean areas in pharmaceutical equipment require appropriate sealing measures. However, due to the special construction of drive motor cables, it is difficult to find an effective method to achieve a sealed passage from the clean area to the non-clean area. This sealing problem increases the complexity of equipment design and also increases the risk of contamination.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0041] The dustproof mobile workbench 100 of the present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0042] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The following is for reference. Figures 1-7 A dustproof mobile workbench 100 is described according to an embodiment of the present invention.

[0045] The dustproof mobile workbench 100 according to an embodiment of the present invention, such as Figure 1As shown, it includes: a first moving component 2, a second moving component 3, a moving platform 36, and a transmission component 31. The second moving component 3 is sealed and mounted on the first moving component 2 and reciprocates along the extension direction of the first moving component 2. The moving platform 36 is sealed and mounted on the second moving component 3 and reciprocates along the extension direction of the second moving component 3. The transmission component 31 is mounted on one side of the first moving component 2 and connected to one end of the second moving component 3, driving the moving platform 36 to move along the extension direction of the second moving component 3.

[0046] Specifically, the first moving component 2 enables the dustproof mobile worktable 100 to reciprocate in the extension direction of the first moving component 2, and the second moving component 3 enables the dustproof mobile worktable 100 to reciprocate in the extension direction of the second moving component 3. This not only enables the dustproof mobile worktable 100 to move freely in two directions, but also enables the dustproof mobile worktable 100 to be positioned at a single point, improving the moving accuracy of the dustproof mobile worktable 100. Furthermore, by setting the transmission component 31 to move the power component out of the working environment, the problem of sealing the motor cable is solved.

[0047] In other words, this invention effectively solves the problems of particle generation from friction in the drive motor cable during clean environments and the need for sealing when the cable passes through different clean areas through a sealed design and the coordinated operation of multiple components. Specifically, the sealed connection between the first moving component 2, the second moving component 3, and the transmission component 31 not only enables the dustproof mobile workbench 100 to move freely in both directions but also significantly reduces particle generation and improves the cleanliness of the equipment. Compared with existing technologies, the technical solution of this invention has significant advantages in solving practical technical problems.

[0048] In some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the transmission assembly 31 includes a rotating shaft 311, a second pulley 312, a roller 313, and a first mounting assembly 314. The rotating shaft 311 is mounted on one side of the first moving assembly 2 along the extending direction of the first moving assembly 2. The roller 313 passes through the rotating shaft 311 and is located inside the first mounting assembly 314. The roller 313 reciprocates on the rotating shaft 311 along the extending direction of the rotating shaft 311. The second pulley 312 passes through the roller 313. The rotating shaft 311 drives the second pulley 312 to rotate. The second pulley 312 drives the moving platform 36 to move along the extending direction of the second moving assembly 314. The first mounting assembly 314 passes through the rotating shaft 311 and is connected to the first moving assembly 2.

[0049] The mounting position and orientation of the rotating shaft 311 ensure the effective movement of the transmission assembly 31 within the movable worktable, that is, enabling the second moving assembly 3 to follow the movement of the first moving assembly 2. The design of the roller 313 and the first mounting assembly 314 allows them to move along the extension direction of the rotating shaft 311, thereby enabling the roller 313 to move as shown in the image. Figure 1 The movement of the first moving component 2 in the extending direction, as shown, thereby realizes the movement of the second moving component 3 in the extending direction of the first moving component 2. The concentric arrangement of the second pulley 312 and the roller 313 not only ensures the smoothness of the transmission, but also drives the second pulley 312 to rotate through the rotation of the roller 313, thereby driving the moving platform 36 to move on the second moving component 3, realizing the movement of the dustproof mobile worktable 100 in the extending direction of the second moving component 3. Figure 1 The movement of the second moving component 3 in the extending direction is shown. This design not only solves the movement problem of the transmission component 31 in the moving worktable, but also ensures the smoothness and sealing of the transmission through the concentric arrangement of the roller 313 and the second pulley 312, thus solving the movement and sealing problems of the transmission component 31 in the moving worktable.

[0050] Specifically, the roller 313 and the first mounting assembly 314 can be mounted on the rotating shaft 311 via a sliding first bearing 319 or a ball bearing 319, thereby reducing friction and wear during movement. The second pulley 312 can be connected to the roller 313 via gears or a chain to ensure the accuracy and stability of transmission. As a preferred embodiment, the second conveyor belt 34 can be made of a high-strength, low-friction material to further reduce friction and wear during movement.

[0051] In other words, the present invention achieves effective movement and sealing of the transmission assembly 31 within the mobile worktable through the coordinated operation of the rotating shaft 311, the second pulley 312, the roller 313, and the first mounting assembly 314. Specifically, the rotation of the rotating shaft 311 drives the rotation of the roller 313 and the second pulley 312, thereby driving the movement of the mobile platform 36. This arrangement not only solves the movement problem of the transmission assembly 31 within the dustproof mobile worktable 100 but also ensures smooth transmission and sealing through the concentric arrangement of the roller 313 and the second pulley 312, thus resolving the movement and sealing issues of the transmission assembly 1 within the mobile worktable. Compared with the prior art, the design of the present invention is more compact and efficient, and can effectively reduce friction and wear during movement, improving the working efficiency and service life of the transmission assembly 31.

[0052] In some embodiments of the present invention, such as Figure 4 , Figure 5 The first mounting assembly 314 includes a fifth seal 3141, a roller 3142, and a mounting member 3143. The mounting member 3143 passes through the rotating shaft 311 and is fixed to both ends of the roller 313. The roller 3142 is installed inside the roller 313 and slides on the rotating shaft 311. The fifth seal 3141 is installed between the mounting member 3143 and the roller 313 to seal the roller 313.

[0053] In other words, by setting the roller 3142 to move on the rotating shaft 311, the movement friction of the roller 313 on the rotating shaft 311, which would otherwise generate dust and impurities and pollute the working environment, is avoided. The rolling of the roller 3142 on the rotating shaft 311 prevents the generation of dust and impurities, thereby reducing particle generation and meeting the technical requirements of reducing friction and particle generation in a clean environment. Simultaneously, the roller 3142 also improves the movement efficiency of the roller 313 on the rotating shaft 311, thus improving the working efficiency of the dustproof mobile workbench 100. Furthermore, the fifth seal 3141 further prevents impurities generated during the movement of the roller 313 from entering the working environment, reducing the risk of working environment pollution.

[0054] In some embodiments of the present invention, the rotating shaft 311 is configured as a polygonal shaft structure, and the rollers 3142 are mounted on multiple faces of the rotating shaft 311.

[0055] Specifically, the arrangement of multiple rollers 3142 improves the transmission efficiency of the rotating shaft 311, enabling the rotating shaft 311 to drive the movable worktable to move in the extension direction of the second moving component 3, thereby improving the force transmission efficiency and making the movement of the movable worktable in the extension direction of the second moving component 3 smooth and efficient. The rollers 3142 can be configured as ball bearings, cylindrical components, or other structural components capable of achieving the above functions; these will not be elaborated upon here.

[0056] Preferably, the rotating shaft 311 can be configured as a quadrilateral shaft structure, and one or more rollers 3142 are provided on each of the four planes of the rotating shaft 311. In addition, the rotating shaft 311 can also be configured as other polygonal shaft structures that can achieve the above functions, which will not be described in detail here.

[0057] In some embodiments of the present invention, such as Figure 1 , Figure 3 , Figure 4and Figure 6 The system also includes a mounting platform 1, a second drive component 6, and a second reducer 8. The first moving component 2 is mounted on one end face of the mounting platform 1 and is located on one side of the first moving component 2. The second drive component 6 is mounted on the end face of the mounting platform 1 away from the first moving component 2 and passes through the mounting platform 1 to drive the transmission component 31. The second drive component 6 is sealed to the transmission component 31. One end of the second reducer 8 is connected to the output end of the second drive component 6, and the other end of the second reducer 8 is connected to the transmission component 31.

[0058] Specifically, the mounting platform 1 provides a basic structure, and the first moving component 2 is sealed and mounted on the mounting platform 1, ensuring the dustproof effect of the dustproof mobile workbench 100 during movement. The introduction of the second drive component 6 and the second reducer 8 improves the moving efficiency of the second moving component 3. Simultaneously, the connection between the second drive component 6 and the transmission component 31 prevents the drive component from contaminating the working environment, ensuring the system's sealing and cleanliness, thus solving the problem of reducing friction and particle generation during movement in a clean environment. As a preferred embodiment, the second reducer 8 can be connected to the second drive component 6 and the transmission component 31 via gear transmission or belt transmission to achieve efficient energy transfer and good sealing. Furthermore, the second reducer 8 can employ various materials and structural designs to adapt to different working environments and requirements. For example, wear-resistant materials and sealing structures can be used to enhance its durability and sealing performance. The second drive component 6 can be a motor or cylinder, or any other power mechanism capable of achieving the above functions, which will not be elaborated further here.

[0059] In other words, by introducing the second driving component 6 and the second reducer 8, this invention not only improves the moving efficiency of the second moving component 3, but also ensures the system's sealing performance through the connection between the second driving component 6 and the transmission component 31, thereby effectively solving the problem of reducing friction and particle generation during movement in a clean environment. Compared with the prior art, the technical solution of this invention has higher driving efficiency and better sealing performance, and can better meet the application scenarios with high clean environment requirements, such as the pharmaceutical industry.

[0060] In some embodiments of the present invention, such as Figure 3 , Figure 4 and Figure 6As shown, the transmission assembly 31 further includes a mounting base 315, a third pulley 316, a fourth pulley 317, a third conveyor belt 318, and a first bearing 319. The mounting base 315 is mounted on the mounting platform 1 and located at both ends of the rotating shaft 311. The rotating shaft 311 is mounted on the mounting base 315. The third pulley 316 passes through the rotating shaft 311 and is located within the mounting base 315. One end of the fourth pulley 317 is mounted on the output end of the second drive member 6. The third conveyor belt 318 connects the third pulley 316 and the fourth pulley 317. The fourth pulley 317 drives the third pulley 316 to rotate. The first bearing 319 passes through the rotating shaft 311 and is located on both sides of the third pulley 316.

[0061] The mounting base 315 provides stable support, and the third pulley 316 and the fourth pulley 317 are connected by the third conveyor belt 318, achieving efficient power transmission. The use of the first bearing 319 reduces friction on the rotating shaft 311, thereby reducing particle generation and meeting the technical requirements for reducing friction and particle generation in clean environments. Furthermore, the mounting base 315 can be made of high-strength materials to ensure its stability under high loads. The third pulley 316 and the fourth pulley 317 can be made of precision-machined metal materials to improve transmission efficiency and reduce wear. The third conveyor belt 318 can be made of high-strength, low-friction materials, such as polyurethane or Teflon, to further reduce friction and particle generation. The first bearing 319 can be ceramic, due to its low coefficient of friction and long lifespan.

[0062] Specifically, by adding the mounting base 315, the third pulley 316, the fourth pulley 317, and the third conveyor belt 318, these components play a crucial role in the transmission assembly 31, ensuring the stability and transmission efficiency of the rotating shaft 311. The mounting base 315 provides stable support, and the third pulley 316 and the fourth pulley 317 are connected by the third conveyor belt 318, achieving efficient power transmission. The use of the first bearing 319 reduces friction on the rotating shaft 311, thereby reducing particle generation and meeting the technical requirements for reducing friction and particle generation in clean environments.

[0063] Therefore, the technical solution of the present invention, by adding the mounting base 315, the third pulley 316, the fourth pulley 317, and the third conveyor belt 318, ensures the stability and transmission efficiency of the rotating shaft 311. Simultaneously, by using the first bearing 319, it reduces the friction of the rotating shaft 311, thereby reducing particle generation and meeting the technical requirements for reducing friction and particle generation in clean environments. Compared with the prior art, the technical solution of the present invention solves the problem of cables crossing different clean areas by installing the drive motor in a normal environment, reducing the friction between the cables and the mounting platform 1, and further reducing particle generation. As a preferred embodiment, the technical solution of the present invention has broad application prospects in the pharmaceutical industry and can effectively solve the problems of friction and particle generation in clean environments.

[0064] In some embodiments of the present invention, such as Figure 6 As shown, the first moving component 2 includes: a first sealed drive shaft 21, a first pulley 22, a first conveyor belt 23, and a first guide rail 24. The first driving member 5 drives the first sealed drive shaft 21 to rotate. The first sealed drive shaft 21 and the first pulley 22 are concentrically arranged to drive the first pulley 22 to rotate. The first pulley 22 drives the first conveyor belt 23 to move. The second moving component 3 is mounted on the first conveyor belt 23 and moves with the first conveyor belt 23. The second moving component 3 cooperates with the first guide rail 24 and reciprocates along the extension direction of the first guide rail 24.

[0065] Specifically, the first sealed drive shaft 21 and the first pulley 22 are concentrically arranged to ensure the stability and accuracy of the transmission. The movement of the first conveyor belt 23 is driven by the first pulley 22. This design reduces friction from direct contact, thereby reducing particle generation.

[0066] In other words, this invention effectively solves the technical problem of reducing friction and particle generation in clean environments. Compared with existing technologies, the technical solution of this invention not only reduces friction but also improves the cleanliness of the environment by reducing particle generation.

[0067] In some embodiments of the present invention, such as Figure 6 As shown, it also includes a carrier plate 25, which is mounted on the first conveyor belt 23 and moves with the first conveyor belt 23. The carrier plate 25 is provided with a guide groove, which cooperates with the first guide rail 24. The carrier plate 25 is mounted on the first guide rail 24 and slides along the extension direction of the first guide rail 24.

[0068] In other words, the guide groove on the carrier plate 25 cooperates with the first guide rail 24, allowing the carrier plate 25 to slide along the extension direction of the guide rail, which further reduces friction.

[0069] In some embodiments of the present invention, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes a first driving component 5 and a first reducer 7. The first driving component 5 is mounted on the end face of the mounting platform 1 away from the first moving component 2 and passes through the mounting platform 1 to drive the first moving component 2. The first driving component 5 is sealed to the first moving component 2. One end of the first reducer 7 is connected to the output end of the first driving component 5, and the other end of the first reducer 7 is connected to the first sealed transmission shaft 21.

[0070] Specifically, the function of the first reducer 7 is to make the power transmission between the output end of the first drive component 5 and the first sealed transmission shaft 21 smoother and more efficient through its speed reduction and torque increase function. As a preferred embodiment, the first reducer 7 can be a gear reducer or a worm gear reducer, which can effectively reduce the speed and increase the torque, thereby ensuring the stability and reliability of power transmission; the first drive component 5 can be a motor, which drives the first sealed transmission shaft 21 through its rotation. Furthermore, the first reducer 7 can further improve transmission efficiency and reduce energy loss by using high-precision gears or worm gears.

[0071] The introduction of the first reducer 7 effectively solves the power transmission problem between the drive component and the moving assembly in the dustproof mobile workbench 100. Compared with the prior art, the present invention, by introducing the first reducer 7, not only improves the efficiency and stability of power transmission, but also reduces particulate matter generated due to unstable power transmission, thereby better meeting the clean environment requirements of the pharmaceutical industry.

[0072] It should be noted that, as Figure 7As shown, the first sealed drive shaft 2121 further includes a first drive shaft 2101, a sealing cylinder 2102, and a sealing ring 2103. The sealing cylinder 2102 is installed inside the mounting platform 1 and passes through the first drive shaft 2101. The sealing ring 2103 is installed between the sealing cylinder 2102 and the sealing ring 2103. The first sealed drive shaft 2121 also includes a second bearing 2105 and a bearing fixing member 2104. The second bearing 2105 is installed inside the sealing cylinder 2102 and passes through the first drive shaft 2101. The bearing fixing member 2104 is installed at the end of the sealing cylinder 2102 away from the first moving component 2 and passes through the first drive shaft 2101. The first sealed drive shaft 2121 further includes a first sealing fastener 2106, a second sealing fastener 2110, a sealing mounting member 2107, and a sixth sealing member 2109. The first sealing fastener 2106 is installed inside the sealing cylinder 2102 and abuts against the second bearing 2105. The sealing mounting member 2107 is installed inside the sealing cylinder 2102 and passes through the first drive shaft 2101. The second sealing fastener 2110 is installed at the end of the sealing cylinder 2102 away from the bearing fastener 2104 and abuts against the sealing mounting member 2107. The sixth sealing member 2109 is installed between the sealing mounting member 2107 and the inner wall of the sealing cylinder 2102. The first sealed drive shaft 2121 also includes a seventh sealing member 2108, which is installed between the first sealing fastener 2106 and the sealing mounting member 2107 and passes through the first drive shaft 2101.

[0073] In some embodiments of the present invention, the second moving component 3 includes: a moving base plate 32, a second guide rail 33, a second conveyor belt 34, and an idler wheel 35. The moving base plate 32 is mounted on the first moving component 2. The idler wheel 35 is mounted on one end of the moving base plate 32. The transmission component 31 is mounted on the mounting platform 1 at the other end of the moving base plate 32. The idler wheel 35 and the transmission component 31 are connected through the second conveyor belt 34. The second guide rail 33 is mounted on the moving base plate 32 along the extending direction of the moving base plate 32. The moving platform 36 is mounted on the second conveyor belt 34 and cooperates with the second guide rail 33 to reciprocate along the extending direction of the second guide rail 33.

[0074] The second moving component 3, through the combination of the transmission component 31, the moving base plate 32, the second guide rail 33, the second conveyor belt 34, the idler wheel 35, and the moving platform 36, achieves dust prevention and friction reduction for the moving platform 36 in a clean environment. Specifically, the transmission component 31 and the idler wheel 35 are connected via the second conveyor belt 34. The transmission component 31 drives the second conveyor belt 34 to move, thereby enabling the workbench connected to the second conveyor belt 34 to follow the movement. Simultaneously, the workbench is mounted on the second guide rail 33, ensuring the stability and sliding properties of the workbench during movement, thus reducing friction and particle generation and meeting the requirements of a clean environment.

[0075] In other words, by installing the drive motor in a normal environment, the problem of cables passing through different clean areas is solved, further reducing the generation of particles in the clean environment.

[0076] It should be noted that the movable base plate 32 can be detachably installed on the carrier plate 25, or the movable base plate 32 can be integrally formed with the carrier plate 25. The installation method of the movable base plate can be set according to the actual production needs, which will not be elaborated here.

[0077] In some embodiments of the present invention, the third conveyor belt 318 is configured as a toothed drive belt.

[0078] In other words, the toothed conveyor belt is configured to correspond to the polygonal structure of the rotating shaft 311. That is, the toothed conveyor belt drives the rotating shaft 311 to rotate, which improves the transmission efficiency of the rotating shaft 311. This enables the rotating shaft 311 to drive the moving worktable to move in the extension direction of the second moving component 3, thereby improving the force transmission efficiency and making the moving worktable move smoothly and efficiently in the extension direction of the second moving component 3.

[0079] In some embodiments of the present invention, such as Figure 4 As shown, it also includes a first seal 9, which is installed between the mounting base 315 and the mounting platform 1.

[0080] Specifically, the first seal 9 can be implemented using various materials and structures. For example, it can be made of rubber to form an annular sealing ring, with its inner diameter matching the flange of the mounting base 315 and its outer diameter matching the groove of the mounting platform 1, thereby forming a tight seal between the mounting base 315 and the mounting platform 1. Alternatively, a metal seal can be used, achieving a sealing effect through elastic deformation. As a preferred embodiment, the first seal 9 can also be designed as a self-lubricating material to reduce friction during installation and disassembly, thereby improving the service life of the seal.

[0081] Therefore, the installation of the first sealing element 9 between the mounting base 315 and the mounting platform 1 ensures a tight seal between them, preventing dust or other contaminants from entering and guaranteeing the cleanliness of the working environment. This design achieves effective sealing through a simple structure, solving the sealing problem between equipment components in a clean environment. Compared with the prior art, the technical solution of the present invention avoids the problem of particles generated by friction of the drive motor cable in a clean environment, while solving the sealing problem of the cable passing through different clean areas, and has the advantages of simple structure and easy implementation.

[0082] In some embodiments of the present invention, such as Figure 4 As shown, the mounting base 315 includes a first cover plate 3151 and a second cover plate 3152. The first cover plate 3151 has a through hole, and one end of the rotating shaft 311 passes through the through hole and is installed inside the mounting base 315. The mounting base 315 also includes a second sealing element 3153 and a third sealing element 3154. The second sealing element 3153 is installed on the first cover plate 3151 of the mounting base 315 to seal the mounting base 315; the third sealing element 3154 is installed on the second cover plate 3152 to seal the mounting base 315. The mounting base 315 also includes a fourth sealing element 3155, which passes through the rotating shaft 311 to seal the through hole position.

[0083] In other words, by providing the first cover plate 3151, the second cover plate 3152, the second seal 3153, the third seal 3154, and the fourth seal 3155 on the mounting base 315, the overall structure of the mounting base 315 is completely sealed, preventing dust and impurities generated during movement within the mounting base 315 from entering the working environment. This simple sealing structure solves the sealing problem between equipment components in a crystalline environment. Compared with existing technologies, the technical solution of this invention avoids the problem of particles generated by friction in the drive motor cable in a clean environment, while also solving the sealing problem of cables crossing different clean areas. It has the advantages of simple structure and ease of implementation.

[0084] like Figure 4 As shown, in some embodiments of the present invention, a dustproof component 10 is also included, which passes through the rotating shaft 311 and is located within the mounting base 315.

[0085] Specifically, the dustproof component 10 can be implemented in various ways. For example, the dustproof component 10 can be in the form of a sealing ring, which is fitted onto the rotating shaft 311 and located inside the mounting base 315 to prevent dust and particles from entering the mounting base 315. As a preferred embodiment, the dustproof component 10 can also be in the form of a dust cover, which wraps around the outside of the rotating shaft 311 and is fixed inside the mounting base 315, thereby effectively isolating external dust and particles. In addition, the dustproof component 10 can also achieve the dustproof effect by providing a dustproof groove on the rotating shaft 311 and filling the dustproof groove with dustproof material.

[0086] Therefore, the dustproof component 10, by passing through the rotating shaft 311 and located within the mounting base 315, effectively prevents dust and particulate matter from entering the mounting base 315, thus solving the dustproof problem when the rotating shaft 311 passes through the mounting base 315. This design ensures that the moving mechanism can remain clean in a clean environment, reducing friction and contamination caused by dust and particulate matter, meeting the high requirements of the pharmaceutical industry for clean environments. Compared with the prior art, the present invention, by setting the dustproof component 10 on the rotating shaft 311, avoids the problem of particles being generated by friction of the drive motor cable in a clean environment, further improving the cleanliness and reliability of the equipment.

[0087] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments of the present invention, a support member 4 is further included. The support member 4 is mounted on the mounting platform 1, and the mounting base 315 is mounted on the support member 4. That is, by setting the support member 4, the transmission component 31 can be stably connected to the second moving component 3, thereby ensuring the stable movement of the second moving component 3 in the extending direction of the first moving component 2.

[0088] In some embodiments of the present invention, such as Figure 1 As shown, it also includes a first sealing cover plate 11 and a second sealing cover plate 12. The first sealing cover plate 11 is mounted on the first moving component 2, and the second sealing cover plate 12 is mounted on the second moving component 3 and passes through the moving platform 36.

[0089] Specifically, the first sealing cover 11 and the second sealing cover 12 effectively prevent friction and particles generated during movement in a clean environment, wherein the first sealing cover 11 passes through the carrier plate 25. The installation of the sealing covers ensures the sealing performance of the first moving assembly 2 and the second moving assembly 3 during movement, thereby reducing friction and particle generation. In a preferred embodiment, the first sealing cover 11 can be bolted to the first moving assembly 2, while the second sealing cover 12 can be fixed to the second moving assembly 3 using snap-fit ​​or other quick-connect methods. This not only solves the problem of reducing friction and particle generation during movement in a clean environment but also ensures the sealing performance of the equipment, preventing cross-contamination between clean and ordinary areas.

[0090] Furthermore, the first sealing cover 11 and the second sealing cover 12 can be made of wear-resistant materials, such as polytetrafluoroethylene (PTFE) or ceramic materials, to further reduce friction and particle generation. In addition, the sealing cover design may include grooves or sealing rings to enhance its sealing performance.

[0091] In other words, by setting the first sealing cover 11 and the second sealing cover 12, the problem of reducing friction and particle generation during movement in a clean environment is effectively solved. Compared with the prior art, the technical solution of the present invention not only improves the sealing performance of the equipment, but also reduces cross-contamination between clean areas and ordinary areas, which has significant advantages.

[0092] In summary, the installation platform 1 separates the upper and lower parts of the equipment, with the upper part being a clean environment and the lower part being a normal environment. This description only shows a portion of the installation platform 1 to better illustrate the mechanism of this invention.

[0093] Direction 1 (Extension direction of the first moving component 2) Transmission method description: The first driving component 5 provides power, driving the first reducer 77 to transmit power to the first pulley 22 through the first sealed transmission shaft 2121. The first pulley 22 drives the first conveyor belt 23, and the carrier plate 25 and the first conveyor belt 23 are installed together. The first conveyor belt 23 drives the carrier plate 25 to move. The first guide rail 24 greatly reduces the resistance to the movement of the entire carrier plate 25. The second bearing 2105 makes the rotation of the first transmission shaft 2101 smoother.

[0094] Direction Two (Extension Direction of the Second Moving Component 3) Transmission Method Description: The second driving component 6 provides power to drive the second reducer 8. The output shaft of the second reducer 8 is equipped with the fourth pulley 317. The second driving component 66 is transmitted to the rotating shaft 311 via the fourth pulley 317, the rotating shaft 311 transmission belt, and the third pulley 316. To ensure smooth rotation of the rotating shaft 311, multiple bearings are provided in the mounting base 315. When the rotating shaft 311 rotates, it drives the second moving component 3 to rotate via multiple rollers 3142 on each plane. The second moving component 3 contains the second pulley 312, which drives the second conveyor belt 34. The second conveyor belt 34 can drive the worktable 36 to move in direction two. The idler pulley 35 ensures that the second conveyor belt 34 is in a taut state. The moving base plate 32 is connected to the carrier plate 25. When the carrier plate 25 moves, it drives the moving base plate 32 to move. Due to the special design of the second moving component 3, the worktable 36 can move freely in the plane.

[0095] In the second moving assembly 3, each surface of the rotating shaft 311 has a roller 3142. When the mechanism moves in direction one, the presence of the rollers 3142 allows the mechanism to move freely in direction two. The rollers 3142 are mounted on the mounting member 3143. The roller 313 is mounted on the roller 313 mounting cylinder, and its main function is to fix the fifth sealing member 3141 in place.

[0096] To ensure sealing of all mechanisms traversing different clean areas, multiple sealing rings are installed, particularly in the transmission structures of direction one and direction two. In the transmission shaft of direction one, the sealing ring 2103 ensures a seal between the mounting platform 1 and the sealing cylinder 2102; the seventh sealing element 2108 ensures a seal between the sealing ring mounting cylinder and the first transmission shaft 2101; and the sixth sealing element 2109 ensures a seal between the sealing cylinder 2102 and the sealing mounting element 2107. In the transmission structure of direction two, the first sealing element 9 is installed between the mounting platform 1 and the mounting base 315, ensuring that the gap in the installation hole does not affect the seal between the mounting platform 1 and the mounting base 315. The two ends of the rotating shaft 311 are cylindrical, and the fourth sealing element 3155 is installed at all points of contact with this cylinder. The third sealing element 3154 is installed between all the mounting end caps of the mounting base 315. The fourth sealing element 3155 ensures a seal. Furthermore, dustproof components 10 are installed at both ends of the rotating shaft 311. The second moving assembly 3 is equipped with a specially designed fifth seal 3141, preventing the diffusion of small amounts of particles generated during friction between the roller 3142 and the rotating shaft 311 into the clean environment. Cover plates are provided on the exterior of all mechanisms involving friction to minimize the diffusion of particles generated by friction into the clean environment. Examples include the first sealing cover 11, the first mounting assembly 314, and the second sealing cover 12.
