[0002] In the pharmaceutical industry, it is necessary to provide a mechanism that can realize the free movement of the workpiece in two directions in the horizontal plane. And when moving in a clean environment, it is necessary to reduce friction as much as possible, thereby reducing the generation of particles. This mechanism is crucial for precise positioning and operation in the pharmaceutical production process.

[0003] However, the existing mechanism has some significant defects. First, the drive motor in one direction is usually installed in a clean environment, which causes the motor cables to be exposed to the clean environment. During the movement of the mechanism, these cables will inevitably rub against other parts, especially the mounting platform, thereby generating a large amount of particles. The generation of these particles seriously affects the maintenance of the clean environment and may have an adverse effect on the quality of drug production.

[0041] A dustproof mobile workbench 100 of the present invention will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0042] In the description of this specification, "one embodiment" or "some embodiments" etc. means that one or more embodiments of this specification include a specific feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

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

[0044] Reference below Figure 1-Figure 7 A dustproof mobile workbench 100 according to an embodiment of the present invention is described.

[0045] According to the dustproof mobile workbench 100 of the embodiment of the present invention, 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 sealedly installed on the first moving component 2, and reciprocates along the extension direction of the first moving component 2, the moving platform 36 is sealedly installed on the second moving component 3 and reciprocates along the extension direction of the second moving component 3, the transmission component 31 is installed 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 realizes the reciprocating movement of the dustproof mobile workbench 100 in the extension direction of the first moving component 2, and the second moving component 3 realizes the reciprocating movement of the dustproof mobile workbench 100 in the extension direction of the second moving component 3. This not only realizes the free movement of the dustproof mobile workbench 100 in two directions, but also realizes the single-point positioning of the dustproof mobile workbench 100, thereby improving the movement accuracy of the dustproof mobile workbench 100. Furthermore, by setting the transmission component 31 to move the power component out of the working environment, the cable sealing problem of the motor is solved.

[0047] That is to say, the present invention effectively solves the problem of the friction of the cable of the drive motor in a clean environment to generate particles and the need to seal the cable when it passes through different clean areas through the sealing design and the coordinated work of multiple components. Among them, the first moving component 2, the second moving component 3 and the transmission component 31 connected by sealing not only realize the free movement of the dustproof mobile workbench 100 in two directions, but also significantly reduce the generation of particles and improve the cleanliness of the equipment. Compared with the prior art, the technical solution of the present invention has significant advantages in solving practical technical problems.

[0048] In some embodiments of the present invention, 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 installation assembly 314, the rotating shaft 311 is installed on one side of the first moving assembly 2 along the extension direction of the first moving assembly 2, the roller 313 is passed through the rotating shaft 311 and is located in the first installation assembly 314, and the roller 313 reciprocates on the rotating shaft 311 along the extension direction of the rotating shaft 311, the second pulley 312 is passed through the roller 313, and the rotating shaft 311 drives the second pulley 312 to rotate, the second pulley 312 drives the moving platform 36 to move along the extension direction of the second moving assembly 3, and the first installation assembly 314 is passed through the rotating shaft 311 and is connected to the first moving assembly 2.

[0049] The installation position and direction of the rotating shaft 311 ensure the effective movement of the transmission assembly 31 in the mobile workbench, that is, the second mobile assembly 3 can follow the movement of the first mobile assembly 2. The design of the roller 313 and the first installation assembly 314 enables them to move along the extension direction of the rotating shaft 311, so as to realize the roller 313 in the following manner: Figure 1 The movement of the first moving assembly 2 in the extension direction shown in the figure, thereby realizing the movement of the second moving assembly 3 in the extension direction of the first moving assembly 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 movement of the mobile platform 36 on the second moving assembly 3, realizing the movement of the dustproof mobile workbench 100 in Figure 1 The second moving assembly 3 shown in the figure moves in the extension direction. This design not only solves the movement problem of the transmission assembly 31 in the mobile workbench, but also ensures the stability and sealing of the transmission through the concentric arrangement of the roller 313 and the second pulley 312, solving the movement and sealing problems of the transmission assembly 31 in the mobile workbench.

[0050] Specifically, the roller 313 and the first mounting assembly 314 can be inserted into the rotating shaft 311 by sliding the first bearing 319 or the first ball bearing 319 to reduce friction and wear during movement. The second pulley 312 can be connected to the roller 313 by a gear or a chain to ensure the accuracy and stability of the 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] That is to say, the present invention realizes the effective movement and sealing of the transmission assembly 31 in the mobile workbench through the coordinated work 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 in the dustproof mobile workbench 100, but also ensures the stability and sealing of the transmission through the concentric arrangement of the roller 313 and the second pulley 312, thereby solving the movement and sealing problems of the transmission group 1 in the mobile workbench. 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, thereby improving the working efficiency and service life of the transmission assembly 31.

[0052] In some embodiments of the present invention, 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 is passed through the rotating shaft 311 and fixed to both ends of the drum 313. The roller 3142 is installed in the drum 313 and slides on the rotating shaft 311. The fifth seal 3141 is installed between the mounting member 3143 and the drum 313 to seal the drum 313.

[0053] That is, by setting the roller 3142 to move on the rotating shaft 311, it is avoided that the roller 313 moves on the rotating shaft 311 and generates dust and impurities that pollute the working environment. The rolling of the roller 3142 on the rotating shaft 311 avoids the generation of dust and impurities, thereby reducing the generation of particles, meeting the technical requirements of reducing friction and particle generation in a clean environment. At the same time, the setting of the roller 3142 also improves the moving efficiency of the roller 313 on the rotating shaft 311, thereby improving the working efficiency of the dust-proof mobile workbench 100. Among them, the setting of the fifth seal 3141 further prevents impurities generated during the movement of the roller 313 from entering the working environment, reducing the risk of pollution of the working environment.

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

[0055] Specifically, the provision of the plurality of rollers 3142 improves the transmission efficiency of the rotating shaft 311, so that the rotating shaft 311 can drive the mobile workbench to move in the extension direction of the second mobile component 3, thereby improving the force transmission efficiency, and making the mobile workbench move smoothly and efficiently in the extension direction of the second mobile component 3. Among them, the rollers 3142 can be set as ball structures, the rollers 3142 can also be set as cylindrical structures, and the rollers 3142 can also be set as other structures that can achieve the above functions, which will not be described one by one here.

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

[0057] In some embodiments of the present invention, Figure 1 , Figure 3 , Figure 4and Figure 6 The figure also includes a mounting platform 1, a second driving member 6 and a second reducer 8, wherein the first moving component 2 is mounted on one end face of the mounting platform 1, and the moving component is mounted on the mounting platform 1 and is located on one side of the first moving component 2; the second driving member 6 is mounted on one end face of the mounting platform 1 away from the first moving component 2 and drives the transmission component 31 through the mounting platform 1, the second driving member 6 is sealedly connected to the transmission component 31, one end of the second reducer 8 is connected to the output end of the second driving member 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 installed on the mounting platform 1 through sealing, which ensures the dustproof effect of the dustproof mobile workbench 100 during the movement. The introduction of the second driving member 6 and the second reducer 8 improves the moving efficiency of the second moving component 3. At the same time, the connection between the second driving member 6 and the transmission component 31 avoids the driving member from being in the working environment and causing pollution to the working environment, ensuring the sealing and clean performance of the system, thereby solving the problem of reducing friction and particle generation when moving in a clean environment. As a preferred embodiment, the second reducer 8 can be connected to the second driving member 6 and the transmission component 31 by gear transmission or belt transmission to achieve efficient energy transfer and good sealing effect. In addition, the second reducer 8 can also adopt a variety of 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 driving member 6 can adopt power members such as motors or cylinders. In addition, the second driving member 6 can also adopt any other power mechanism that can achieve the above functions, which will not be repeated here.

[0059] That is to say, the present invention not only improves the moving efficiency of the second moving assembly 3 by introducing the second driving member 6 and the second reducer 8, but also ensures the sealing of the system through the connection between the second driving member 6 and the transmission assembly 31, thereby effectively solving the problem of reducing friction and particle generation when moving in a clean environment. Compared with the prior art, the technical solution of the present invention has higher driving efficiency and better sealing performance, and can better meet the application scenarios with high requirements for clean environment such as the pharmaceutical industry.

[0060] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6As shown, the transmission assembly 31 further includes a mounting seat 315, a third pulley 316, a fourth pulley 317, a third conveyor belt 318 and a first bearing 319. The mounting seat 315 is mounted on the mounting platform 1 and is arranged at both ends of the rotating shaft 311. The rotating shaft 311 is mounted on the mounting seat 315. The third pulley 316 is passed through the rotating shaft 311 and is arranged in the mounting seat 315. One end of the fourth pulley 317 is mounted on the output end of the second driving 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 is passed through the rotating shaft 311 and is arranged on both sides of the third pulley 316.

[0061] Among them, the mounting seat 315 provides stable support, and the third pulley 316 and the fourth pulley 317 are connected through the third conveyor belt 318 to achieve efficient transmission of power. The use of the first bearing 319 reduces the friction of the rotating shaft 311, thereby reducing the generation of particles, and meets the technical requirements of reducing friction and particle generation in a clean environment. Further, the mounting seat 315 can be made of high-strength material to ensure its stability under high load. 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 coefficient materials, such as polyurethane or Teflon, to further reduce friction and particle generation. The first bearing 319 can be selected from ceramic first bearings 319 because of its low friction coefficient and long life.

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

[0063] Therefore, the technical solution of the present invention ensures the stability and transmission efficiency of the rotating shaft 311 by adding the mounting seat 315, the third pulley 316, the fourth pulley 317 and the third conveyor belt 318, and at the same time reduces the friction of the rotating shaft 311 by using the first bearing 319, thereby reducing the generation of particles, and meeting the technical requirements of reducing friction and particle generation in a clean environment. 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 an ordinary environment, reduces the friction between the cables and the mounting platform 1, and further reduces the generation of particles. 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 a clean environment.

[0064] In some embodiments of the present invention, Figure 6 As shown, the first moving component 2 includes: a first sealed transmission 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 transmission shaft 21 to rotate, the first sealed transmission 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 installed on the first conveyor belt 23 and moves following 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 transmission shaft 21 is arranged concentrically with the first pulley 22 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 the friction of direct contact, thereby reducing the generation of particles.

[0066] That is to say, the present invention effectively solves the technical problem of reducing friction and particle generation in a clean environment. Compared with the prior art, the technical solution of the present invention not only reduces friction, but also improves the effect of maintaining a clean environment by reducing the generation of particles.

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

[0068] That is, the cooperation between the guide groove on the carrying plate 25 and the first guide rail 24 enables the carrying plate 25 to slide along the extension direction of the guide rail. This sliding mode further reduces friction.

[0069] In some embodiments of the present invention, Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes a first driving member 5 and a first reducer 7. The first driving member 5 is installed on an 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 member 5 is sealed and connected to the first moving component 2; one end of the first reducer 7 is connected to the output end of the first driving member 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 driving member 5 and the first sealed transmission shaft 21 more stable and efficient through its function of reducing speed and increasing torque. As a preferred embodiment, the first reducer 7 can adopt 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 driving member 5 can adopt a motor, and drive the first sealed transmission shaft 21 through the rotation of the motor. In addition, the first reducer 7 can further improve the transmission efficiency and reduce energy loss by adopting high-precision gears or worm gears.

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

[0072] It should be noted that if Figure 7As shown, the first sealed transmission shaft 2121 further includes a first transmission shaft 2101, a sealing cylinder 2102 and a sealing ring 2103.

The first sealing fixture 2106 is installed in the sealing cylinder 2102 and stops at the second bearing 2105. The sealing installation 2107 is installed in the sealing cylinder 2102 and penetrates the first transmission 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 installed on the first moving component 2, the idler wheel 35 is installed at one end of the moving base plate 32, the transmission component 31 is installed on the mounting platform 1 at the other end of the moving base plate 32, the idler wheel 35 is connected to the transmission component 31 through the second conveyor belt 34, the second guide rail 33 is installed on the moving base plate 32 along the extension direction of the moving base plate 32, and the moving platform 36 is installed on the second conveyor belt 34 and cooperates with the second guide rail 33 to reciprocate along the extension direction of the second guide rail 33.

[0074] The second moving component 3 realizes dust prevention and friction reduction of the mobile platform 36 in a clean environment through the combination of the transmission component 31, the mobile bottom plate 32, the second guide rail 33, the second conveyor belt 34, the idler wheel 35 and the mobile platform 36. Specifically, the transmission component 31 is connected to the idler wheel 35 through the second conveyor belt 34, and 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. At the same time, the workbench is installed on the second guide rail 33, which ensures the stability and sliding of the workbench during the movement, thereby reducing friction and particle generation, and meeting the requirements of a clean environment.

[0075] That is to say, 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 bottom plate 32 can be detachably mounted on the carrier plate 25, and the movable bottom plate 32 can also be integrally formed with the carrier plate 25. The installation method of the movable bottom plate is set according to actual production requirements and will not be described in detail here.

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

[0078] That is to say, the toothed conveyor belt corresponds to the polygonal structure of the rotating shaft 311, that is, the rotating shaft 311 is driven to rotate by the toothed conveyor belt, thereby improving the transmission efficiency of the rotating shaft 311, so that the rotating shaft 311 can drive the mobile workbench to move in the extension direction of the second moving component 3, thereby improving the force transmission efficiency and enabling the mobile workbench to move smoothly and efficiently in the extension direction of the second moving component 3.

[0079] In some embodiments of the present invention, Figure 4 As shown, a first sealing member 9 is also included, and the first sealing member 9 is installed between the mounting seat 315 and the mounting platform 1.

[0080] Specifically, the first seal 9 can be implemented by a variety of materials and structures. For example, a rubber material can be used to make an annular seal ring, whose inner diameter matches the flange of the mounting seat 315 and whose outer diameter matches the groove of the mounting platform 1, so as to form a tight seal between the mounting seat 315 and the mounting platform 1. In addition, a metal seal can also be used to achieve a sealing effect through elastic deformation. As a preferred embodiment, the first seal 9 can also be designed as a material with a self-lubricating function to reduce friction during installation and disassembly and increase the service life of the seal.

[0081] Therefore, the installation of the first seal 9 between the mounting seat 315 and the mounting platform 1 ensures the sealing between the two, thereby preventing dust or other pollutants from entering and ensuring the cleanliness of the working environment. This design achieves effective sealing through a simple structure and solves 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 cable of the drive motor in a clean environment, and solves 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, Figure 4 As shown, the mounting seat 315 includes the first cover plate 3151 and the second cover plate 3152. The first cover plate 3151 is provided with a through hole, and one end of the rotating shaft 311 passes through the through hole and is installed in the mounting seat 315. The mounting seat 315 also includes the second sealing member 3153 and the third sealing member 3154. The second sealing member 3153 is installed on the first cover plate 3151 of the mounting seat 315 to seal the mounting seat 315; the third sealing member 3154 is installed on the second cover plate 3152 to seal the mounting seat 315. The mounting seat 315 also includes the fourth sealing member 3155, which is penetrated on the rotating shaft 311 to seal the through hole.

[0083] That is, by arranging 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 seat 315, the overall structure of the mounting seat 315 is completely sealed, so that dust and impurities generated by the structure in the mounting seat 315 during movement are prevented from entering the working environment, and the sealing problem between equipment components in a crystallization environment is solved by a simple sealing structure. Compared with the prior art, the technical solution of the present invention avoids the problem of particles generated by friction of the cable of the drive motor in a clean environment, and solves the sealing problem of the cable passing through different clean areas, and has the advantages of simple structure and easy implementation.

[0084] like Figure 4 As shown, in some embodiments of the present invention, a dustproof member 10 is further included. The dustproof member 10 is passed through the rotating shaft 311 and is located in the mounting seat 315 .

[0085] Specifically, the dustproof member 10 can be implemented in a variety of ways. For example, the dustproof member 10 can be in the form of a sealing ring, which is sleeved on the rotating shaft 311 and located in the mounting seat 315 to prevent dust and particles from entering the mounting seat 315. As a preferred embodiment, the dustproof member 10 can also be in the form of a dust cover, which is wrapped around the outside of the rotating shaft 311 and fixed in the mounting seat 315, thereby effectively isolating dust and particles from the outside. In addition, the dustproof member 10 can also achieve a dustproof effect by setting a dustproof groove on the rotating shaft 311 and filling the dustproof groove with dustproof material.

[0086] Thus, the dustproof member 10 is passed through the rotating shaft 311 and is located in the mounting seat 315, effectively preventing dust and particles from entering the mounting seat 315, thereby solving the dust prevention problem when the rotating shaft 311 is passed through the mounting seat 315. This design ensures that the motion mechanism in a clean environment can be kept clean, reduces friction and pollution caused by dust and particles, and meets the high requirements of the pharmaceutical industry for a clean environment. Compared with the prior art, the present invention avoids the problem of particles generated by friction of the cable of the drive motor in a clean environment by arranging the dustproof member 10 on the rotating shaft 311, 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 seat 315 is mounted on the support member 4. That is, by providing the support member 4, the transmission assembly 31 can be stably connected to the second moving assembly 3, thereby ensuring the stable movement of the second moving assembly 3 in the extension direction of the first moving assembly 2.

[0088] In some embodiments of the present invention, 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 installed on the first moving component 2 , and the second sealing cover plate 12 is installed on the second moving component 3 and penetrates the moving platform 36 .

[0089] Specifically, the arrangement of the first sealing cover plate 11 and the second sealing cover plate 12 effectively prevents the friction and particles generated during movement in a clean environment, wherein the first sealing cover plate 11 is inserted through the carrier plate 25. By installing the sealing cover plates, the sealing of the first moving component 2 and the second moving component 3 during movement is ensured, thereby reducing the generation of friction and particles. As a preferred embodiment, the first sealing cover plate 11 can be fixed to the first moving component 2 by bolts, and the second sealing cover plate 12 can be fixed to the second moving component 3 by snaps or other quick connection methods. In this way, not only the problem of reducing friction and particle generation during movement in a clean environment is solved, but also the sealing of the equipment is ensured, and cross-contamination between clean areas and ordinary areas is prevented.

[0090] Furthermore, the first sealing cover plate 11 and the second sealing cover plate 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 design of the sealing cover plate can also include a groove or a sealing ring to enhance its sealing performance.

[0091] That is to say, by providing the first sealing cover plate 11 and the second sealing cover plate 12, the problem of reducing friction and particle generation when moving 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 the cross contamination between the clean area and the ordinary area, which has significant advantages.

[0092] In summary, the installation platform 1 separates the upper and lower parts of the device, with the upper part being a clean environment and the lower part being a normal environment. In this description, only a part of the installation platform 1 is captured in order to better illustrate the mechanism of this invention.

[0093] Transmission mode description of direction 1 (extending direction of the first moving component 2): the first driving member 5 provides power, drives 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 allows the first transmission shaft 2101 to rotate more smoothly.

[0094] The transmission mode in direction two (the extension direction of the second moving assembly 3) is described. The second driving member 6 provides power to drive the second reducer 8. The output shaft of the second reducer 8 is equipped with the fourth pulley 317, and the second driving member 66 is transmitted to the rotating shaft 311 through the fourth pulley 317, the transmission belt of the rotating shaft 311, and the third pulley 316316. In order to ensure the smooth rotation of the rotating shaft 311, a plurality of bearings are arranged in the mounting seat 315. When the rotating shaft 311 rotates, it will drive the second moving assembly 3 to rotate through the plurality of rollers 3142 on each plane. The second moving assembly 3 has the second pulley 312, and the second pulley 312 drives the second conveyor belt 34. The second conveyor belt 34 can drive the workbench 36 to move in direction two, and the idler wheel 35 ensures that the second conveyor belt 34 is in a tensioned state. The moving bottom plate 32 is connected to the carrying plate 25, and the carrying plate 25 will drive the moving bottom plate 32 to move when it moves. Due to the special design of the second moving component 3, the working table 36 can be guaranteed to move freely in a plane.

[0095] In the second moving assembly 3, each surface of the rotating shaft 311 has the roller 3142. When the mechanism moves in direction 1, the mechanism in direction 2 can move freely due to the existence of the roller 3142. The roller 3142 is installed on the mounting member 3143. The roller 313 is installed on the roller 313 mounting cylinder, and its main function is to fix the fifth sealing member 3141.

[0096] In order to ensure the sealing of all mechanisms passing through different clean areas, multiple sealing rings are provided, especially in the transmission structure of direction one and the transmission structure of direction two, to ensure sealing. In the transmission shaft of direction one, the sealing ring 2103 ensures the sealing between the mounting platform 1 and the sealing cylinder 2102, the seventh sealing member 2108 ensures the sealing between the sealing ring mounting cylinder and the first transmission shaft 2101, and the sixth sealing member 2109 ensures the sealing between the sealing cylinder 2102 and the sealing mounting member 2107. In the transmission structure of direction two, the first sealing member 9 is installed between the mounting platform 1 and the mounting seat 315 to ensure that the gap of the installation hole will not affect the sealing between the mounting platform 1 and the mounting seat 315. The two ends of the rotating shaft 311 are cylindrical, and the fourth sealing member 3155 is provided at all places in contact with the cylinder, and the third sealing member 3154 is provided between all the mounting end covers of the mounting seat 315, and the fourth sealing member 3155 ensures sealing. The dustproof parts 10 are installed at both ends of the rotating shaft 311. The specially designed fifth seal 3141 is installed in the second moving component 3, and the small amount of particles generated by the friction between the roller 3142 and the rotating shaft 311 will not spread into the clean environment. Cover parts are set outside all mechanisms with friction to minimize the spread of particles generated by friction into the clean environment. Such as the first sealing cover plate 11, the first mounting component 314, and the second sealing cover plate 12.
