[0002] Cryopumps are key equipment for achieving high vacuum and ultra-high vacuum environments. Among them, cryopumps are vacuum pumps that use low-temperature surfaces to adsorb gas molecules. They can effectively remove various gas molecules including hydrogen, so they are widely used in high-end technology fields such as semiconductor manufacturing, space simulation, and particle accelerators.

[0003] Cryogenic pumps cool the adsorption surface inside the pump body to an extremely low temperature (usually below the boiling point of the gas), which slows down the thermal motion of the gas molecules and eventually adsorbs and fixes them. This adsorption effect is effective for all gases, especially for light gases (such as hydrogen) that are difficult to pump with traditional mechanical pumps.

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0041] like Figure 1-Figure 10 As shown, a cryogenic vacuum pump cold umbrella processing equipment includes a protective cover 10, and the protective cover 10 is divided into an upper protective cover 11 and a lower protective cover 12;

[0042] It also includes a guide plate 20, which is fixedly connected between the upper protective cover 11 and the lower protective cover 12, and an activated carbon inlet 21 is provided on the guide plate 20;

[0043] The middle cavity 30 is rotatably disposed in the guide plate 20, and the middle cavity 30 includes a cavity cover plate 31, and the cavity cover plate 31 is fixedly connected with a middle positioning block 32, an array positioning block 33 and a middle avoidance block 34;

[0044] A guide ring 40, the guide ring 40 is slidably placed in the middle cavity 30;

[0045] A driving assembly 50, the driving assembly 50 includes a driving motor 51 detachably connected to the middle cavity 30, and the driving assembly 50 also includes a vibrator 52 slidably connected to the protective cover 10;

[0046] The flip assembly 60 is slidably connected to the protection cover 10 .

[0047] It should be noted that a latch pin (not shown) is fixed on the cavity cover plate 31. An activated carbon outlet is also provided on the protective cover 10. The protective cover 10, the guide plate 20, the middle cavity 30 and the guide ring 40 are combined into a mold for forming a cold umbrella. A cold plate is also provided in conjunction with the cold umbrella mold for placing the formed cold umbrella model.

[0048] In this embodiment, the protective cover 10 is used to protect the key components inside the mold from the influence of the external environment, and also plays a role of fixing and supporting. Ensure the sealing of the equipment mold during use, and facilitate maintenance and operation. Among them, the protective cover 10 is divided into an upper protective cover 11 and a lower protective cover 12. Through the setting of the two protective covers, the stability of the structure is guaranteed, and it is easy to disassemble and install. The guide plate 20 is used to guide the activated carbon material so that the material for making the cold umbrella can smoothly enter the middle cavity 30. By fixing the guide plate 20 between the upper protective cover 11 and the lower protective cover 12, a cavity can be effectively formed to place the material. Specifically, an activated carbon inlet 21 is provided on the guide plate 20, so that the activated carbon can be easily added to the mold to complete the production of the cold umbrella. Among them, the middle cavity 30 is the main core area of ​​mold molding. By rotating the middle cavity 30 in the guide plate 20, it is convenient to control the middle cavity 30. Specifically, the middle cavity 30 includes a cavity cover plate 31, which is used to provide a molding range to ensure that the thickness of the cold umbrella after molding can meet the use specifications and can be used smoothly. The middle positioning block 32, the array positioning block 33 and the middle avoidance block 34 are fixedly connected to the cavity cover plate 31. The middle cavity 30 can maintain a stable posture during the rotation process while avoiding interference with other components. At the same time, a molding space is provided for the middle cavity 30, so that a high degree of stability and precision can be maintained during the processing process. Ensure that the cold umbrella after molding can be directly used by the low-temperature vacuum pump. The guide ring 40 is used to fix the cold umbrella after molding to ensure that the mold will not crack and disperse when it is turned over and placed. By sliding the guide ring 40 in the middle cavity 30, the material in the middle cavity 30 is prevented from falling off due to excessive gaps. The drive assembly 50 is used to drive the middle cavity 30 to rotate so that the space inside the cavity is filled with activated carbon. Among them, the driving assembly 50 includes a driving motor 51 detachably connected to the middle cavity 30, and the driving motor 51 provides power for the rotation of the middle cavity 30. The driving assembly 50 also includes a vibrator 52 slidably connected to the protective cover 10, and the vibrator 52 is used to generate vibrations to help the equipment to achieve the filling of the material in the space of the middle cavity 30 during the processing process, so that the cavity is filled with activated carbon to ensure uniform density after molding. The flip assembly 60 is used to drive the cold umbrella mold to rotate, and is slidably connected to the protective cover 10 to drive the mold to flip, so that the cold umbrella formed in the mold is easier to take and put. It can ensure that the molded model can be placed and installed with the cold plate.

[0049] like Figure 4 , Figure 6As shown, the upper protective cover 11 and the lower protective cover 12 are respectively provided with fixing holes 13 along the center array of the protective cover 10, through which the fixing holes 13 can be used to install fasteners, and the fasteners are connected to the guide plate 20, so that the protective cover 10 is firmly fixed on the guide plate 20. It not only helps the stability and safety of the protective cover 10 when in use, but also simplifies the maintenance and replacement process of the cold umbrella mold. Among them, the upper protective cover 11 and the lower protective cover 12 are also respectively provided with intermediate spaces 14. The intermediate space 14 can easily drive the intermediate cavity 30 provided inside to ensure that the intermediate cavity 30 rotates.

[0050] Preferably, the number of guide plates 20 is three, and the three guide plates 20 are used in conjunction to provide a suitable height for placing the middle cavity 30, so that the cold umbrella model can be smoothly formed in the mold. Specifically, placement holes 22 are opened on the guide plate 20 along the central array of the guide plate 20, and these placement holes 22 correspond to the fixing holes 13. The placement holes 22 can be fixedly connected to the fixing holes 13 by fasteners. It can ensure a firm connection between the guide plate 20 and the cavity cover plate 31, thereby improving the stability and reliability of the mold. The guide plate 20 is used to effectively support and guide related accessories, providing important support for the normal use of the mold. It can effectively reduce the risk of loosening or falling off, and ensure that the mold can operate stably under various working conditions.

[0051] like Figure 4 , Figure 6 As shown, there are two cavity cover plates 31, and the molding range of the mold is formed by two cavity cover plates 31. Specifically, each cavity cover plate 31 has a connecting hole 311, and these connecting holes 311 are used to connect the middle positioning block 32 to ensure the stability and reliability of the middle cavity 30. In addition, the cavity cover plate 31 is also provided with an array hole 312 along the connecting hole 311 as the center array, in order to achieve specific arrangement and installation requirements, and ensure that the shape of the mold molding cavity can match the low-temperature vacuum pump. At the same time, it can facilitate the subsequent maintenance of the installation of the array positioning block 33, and at the same time ensure that a specific shape suitable for the vacuum pump is formed in the cavity cover plate 31.

[0052] Preferably, the thickness of the middle positioning block 32 is 5 mm. By limiting the thickness of the middle positioning block 32, it is possible to ensure that the thickness of the cold umbrella model formed in the middle cavity 30 is more accurate. Among them, by fixing the middle positioning block 32 between the two cavity cover plates 31, not only the stability of the middle positioning block 32 is ensured, but also the precise positioning between the cavity cover plates 31 can be achieved. Specifically, a positioning hole 321 is provided on the middle positioning block 32 for placing fasteners and fixing it to the cavity cover plate 31. It should be noted that the positioning hole 321 is fixedly connected to the connecting hole 311 by fasteners, which can effectively maintain the thickness of the middle cavity 30 formed, and ensure that the cold umbrella model formed in the mold cavity can be used normally.

[0053] Preferably, the thickness of the middle avoidance block 34 is 5 mm. By limiting the thickness of the middle avoidance block 34, the middle avoidance block 34 can effectively cooperate with the middle positioning block 32 when in use to complete the support of the cavity cover plate 31. Among them, by fixing the middle avoidance block 34 between the two cavity cover plates 31, it can be ensured that the middle avoidance block 34 can be coordinated with the middle positioning block 32 and the array positioning block 33 during assembly, thereby ensuring the stability of the entire mold forming cavity. Specifically, by sleeve-mounting the middle avoidance block 34 on the outside of the middle positioning block 32, the stable use of the middle positioning block 32 can be effectively ensured, and it can be ensured that the middle positioning block 32 will not move due to external materials when in use.

[0054] Preferably, the thickness of the array positioning block 33 is 5 mm. By limiting the thickness of the array positioning block 33, accurate positioning and stable connection can be guaranteed during the assembly process of the cold umbrella mold forming cavity. Specifically, the number of array positioning blocks 33 is six. By setting six array positioning blocks 33, it can be effectively ensured that the formed cold umbrella model can fit the low-temperature vacuum pump. At the same time, it can ensure that suitable support and fixation are obtained between the cavity cover plates 31. Specifically, the six array positioning blocks 33 are fixed between the two cavity cover plates 31 to ensure the stability and reliability of the entire intermediate cavity 30 structure. It should be noted that fastening holes 331 are respectively provided on the array positioning blocks 33 for placing fasteners to complete the fixation with the cavity cover plate 31. Among them, the fastening holes 331 are fixedly connected to the array holes 312 by fasteners, which ensures the convenience of the array positioning blocks 33 during the installation process, and can also ensure the firmness and stability of the cold umbrella mold forming cavity, thereby ensuring the normal operation and service life of the entire cold umbrella mold.

[0055] like Figure 4 , Figure 6 , Figure 7As shown, the guide ring 40 is a metal sheet, usually made of steel plate, to ensure that the guide ring 40 has good durability and stability. It should be noted that the guide ring 40 is used in conjunction with the back plate 41. Among them, the back plate 41 is also made of metal plate, and the thickness of the back plate 41 is usually less than 1 mm. The guide ring 40 and the back plate 41 can provide stable support and guiding effects to ensure the fixation and use of the cold umbrella mold after molding. At the same time, it can ensure that the formed cold umbrella model will not move when it is flipped. It can ensure the normal operation and use of the cold umbrella after molding, and will not cause the cold umbrella model to break when the mold is flipped and taken out.

[0056] like Figure 2 , Figure 3 , Fig. 9 As shown, the driving component 50 is an important component of the processing equipment, and has multiple functions, which can effectively assist the cold umbrella forming process. Among them, the driving component 50 also includes a lifting push rod 53, and the lifting push rod 53 is used to drive the driving motor 51 and the vibrator 52 to move, so as to prevent the flipping motor 62 from colliding with the driving motor 51 when driving the mold to flip. Among them, the output end of the lifting push rod 53 is fixedly connected with a driving plate 54, and the driving plate 54 is used to provide effective support for the driving motor 51 and the vibrator 52 to ensure the stability when driving and vibrating the mold. Specifically, the driving plate 54 is fixedly connected with the driving motor 51 and the vibrator 52. By fixing the driving motor 51 and the vibrator 52 above the driving plate 54, the lifting and lowering adjustment of the driving motor 51 and the vibrator 52 can be effectively realized;

[0057] Among them, the driving motor 51 is the power source for driving the middle cavity 30 to rotate. By passing the output end of the driving motor 51 through the middle space 14, a detachable connection is formed with the cavity cover 31. It is not only convenient for daily maintenance and replacement, but also ensures that the driving motor 51 can transmit power stably and efficiently. Among them, a groove for clamping with the cavity cover 31 is fixedly provided at the output end of the driving motor 51, and the clamping work of the driving motor 51 and the cavity cover 31 is performed. Through the cooperation of the groove and the pin, the middle cavity 30 can be effectively driven to rotate. Specifically, the vibrator 52 is responsible for generating a vibration effect, which is used to drive the mold to shake. Among them, an adsorption disk that matches the surface of the protective cover 10 is fixedly provided at the output end of the vibrator 52, which can ensure that the vibrator 52 can effectively drive the protective cover 10 when working, thereby effectively driving the mold to shake, so that the activated carbon in the mold molding cavity is tighter.

[0058] like Figure 3 , Fig. 9 , Fig.10As shown, the flip assembly 60 is fixedly arranged at the bottom of the driving assembly 50, and can be effectively used in conjunction with the driving assembly 50. The flip assembly 60 includes a support plate 61, which is the basis of the entire flip assembly 60. The support plate 61 bears the weight of the entire device and fixes the flip assembly 60 in a suitable position. The support plate 61 is fixedly connected to the lifting push rod 53. By fixing the support plate 61 at the bottom of the lifting push rod 53, it is beneficial to effectively remove the material from the output end of the driving assembly 50 when the mold is flipped and adjusted, so as to prevent the material in the mold from moving when flipping. Among them, a flip motor 62 is fixedly arranged on the support plate 61. The flip motor 62 is a key component for realizing the flipping action. The flip motor 62 can effectively provide a flipping force, thereby driving the mold to flip. Specifically, the output end of the flip motor 62 is fixedly connected with a flip sleeve 63. When the flip motor 62 is started, it will drive the flip sleeve 63 to rotate, and the flip sleeve 63 is fitted with the mold, so that the flip sleeve 63 drives the mold to flip.

[0059] It should be noted that the support plate 61 is also fixedly connected with an adjustment motor 64, wherein the adjustment motor 64 is used to drive the adjustment plate 65 to move, thereby driving the flip motor 62 and the flip sleeve 63 to approach the mold, and completing the fitting and disassembly with the mold. Among them, the output end of the adjustment motor 64 is fixedly connected with the adjustment plate 65, thereby driving the adjustment plate 65 to adjust, and at the same time, the flip assembly 60 can be effectively supported and fixed by the adjustment plate 65. Specifically, the flip motor 62 is fixedly connected to the adjustment plate 65. By driving the adjustment motor 64, the position of the flip motor 62 can be adjusted, thereby achieving precise control of the flip action. The adaptability and flexibility of the flip assembly 60 are improved. At the same time, the flip assembly 60 also has the advantages of simple structure and convenient maintenance, which reduces the production cost and maintenance cost. The flip assembly 60 realizes fast and efficient flipping and processing of the mold through precise flipping and adjustment actions, thereby improving production efficiency and the automation level of the equipment.

[0060] The working principle of the present invention is as follows: when the cold umbrella needs to be processed, the lower protective cover 12 in the protective cover 10 is placed on the output end of the driving motor 51 and the vibrator 52 in the driving assembly 50. The guide plate 20 is placed above the lower protective cover 12, and the cavity cover plate 31 is placed on the first guide plate 20 placed, and the output end of the driving motor 51 is clamped through the pin on the cavity cover plate 31. The middle positioning block 32, the middle avoidance block 34 and the array positioning block 33 are placed on the cavity cover plate 31 in sequence. Then another cavity cover plate 31 is placed on top, and the two cavity cover plates 31, the middle positioning block 32 and the array positioning block 33 are fixed by fasteners. The middle cavity 30 is formed, which is the molding cavity in the cold umbrella mold. By placing the other two guide plates 20 on top in sequence, and finally placing the upper protective cover 11 on the top. The protective cover 10 and the guide plate 20 are fixed by fasteners. By adding activated carbon into the mold from the activated carbon inlet 21 on the guide plate 20, the activated carbon enters the mold cavity. After the activated carbon enters the middle cavity 30, the middle cavity 30 is driven to rotate by the driving motor 51 in the driving assembly 50, so that the space in the middle cavity 30 is filled with activated carbon. The vibrator 52 drives the mold to vibrate and shake, so that the activated carbon in the middle cavity 30 is more tightly fastened, and there will be no empty space in the middle cavity 30, ensuring that the density of the cold umbrella model formed in the middle cavity 30 is consistent. After the cold umbrella model is formed, the upper protective cover 11, the guide plate 20, and the upper cavity cover plate 31 are disassembled in turn, and the guide ring 40 is slid into the middle cavity 30, and the back plate 41 is placed above the guide ring 40 (it should be noted that the back plate 41 needs to be coated with glue, and the viscosity of the glue should not be too high, and it is OK to be slightly sticky). Then the cavity cover plate 31, the guide plate 20 and the upper protective cover 11 are restored. The adjusting motor 64 in the flip assembly 60 drives the adjusting plate 65, so that the adjusting plate 65 drives the flip motor 62 and the flip sleeve 63 to fit the mold, and then the flip motor 62 drives the mold to flip. The lower protective cover 12, the guide plate 20 and the cavity cover plate 31 of the flipped mold are disassembled in sequence, and the prepared cold plate is placed on the cold umbrella model. The processing and molding of the cold umbrella is completed by disassembling other mold parts.

[0061] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
