Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum equipment technology, and in particular to a connection device for vacuum equipment and a vacuum equipment. Background Technology
[0002] The connection device of a vacuum equipment is a key component ensuring stable operation, and its performance directly affects the equipment's operating efficiency and maintenance costs. The water-cooled plate, as a core temperature control component within the vacuum equipment, needs to be connected to external water or gas systems via the connection device to ensure timely heat dissipation and prevent localized overheating that could negatively impact the coating effect. Simultaneously, during the coating process, sputtered material extensively deposits on the chamber walls and surfaces of the water-cooled plate. With increasing cycle count, the thickening of the deposited layer can compromise vacuum stability and reduce the heat exchange efficiency of the water-cooled plate. Therefore, the connection device must be periodically disassembled for cleaning and maintenance of the water-cooled plate.
[0003] In existing technologies, the connection methods for vacuum equipment connection devices are mostly welding and flange fixing structures. Welded connections require cutting with an angle grinder during disassembly, which is time-consuming and labor-intensive. Furthermore, the cutting process easily generates metal dust, contaminating the vacuum chamber and affecting coating quality and subsequent processes. In addition, there are safety hazards associated with hot work. While flange fixing eliminates the need for cutting, it is cumbersome to assemble and disassemble, reducing work efficiency.
[0004] Therefore, there is an urgent need to design a connection device and vacuum equipment for vacuum equipment to solve the above technical problems. Utility Model Content

[0043] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.
[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0045] This embodiment provides a connection device for vacuum equipment, which can improve the efficiency of disassembly and assembly, avoid contamination of the vacuum chamber, and reduce safety hazards.
[0046] like Figures 1-3As shown, the connection device for the vacuum equipment mainly includes a fixing member 10, a media transmission assembly 20, a sealing assembly 30, and a manual operating member 40. The fixing member 10 is configured to be fixedly connected to the furnace body 100 of the vacuum equipment, and external threads are provided on the outer periphery of the fixing member 10. A portion of the sealing assembly 30 is disposed between the media transmission assembly 20 and the fixing member 10. The manual operating member 40 is sleeved on the media transmission assembly 20 and the fixing member 10, and is screwed into the external threads on the fixing member 10.
[0047] Based on the above design, in this embodiment, the manual operating component 40 and the fixing component 10 are connected by an external thread. Disassembly and assembly only require rotating the manual operating component 40, eliminating the need for any cutting operations. This fundamentally eliminates the risk of hot work and prevents the generation of metal dust, ensuring the cleanliness of the vacuum chamber 110. Traditional welding and flange connections significantly consume maintenance time. In this embodiment, the connection device for vacuum equipment, through the threaded connection between the manual operating component 40 and the fixing component 10, allows for the disassembly and assembly of the sealing component 30 and the media transmission component 20 simply by rotating, without the need for complex tools. This significantly shortens disassembly and assembly time and improves work efficiency.
[0048] Furthermore, in this connection device for vacuum equipment, apart from the fixing component 10, the media transmission component 20, the sealing component 30, and the manual operating component 40 can all be quickly disassembled and replaced. For example, when the sealing component 30 ages, only the sealing component 30 needs to be replaced; there is no need to replace the fixing component 10 or the connection device for vacuum equipment, significantly reducing maintenance costs and spare parts consumption. In this embodiment, the sealing component 30 can form a seal during the rotation and compression process of the manual operating component 40, thereby improving sealing performance and reducing or preventing media leakage.
[0049] For example, the fixing member 10 in this embodiment is made of 304 stainless steel. The manual operating member 40 is set as a pendant handle with a scalloped thread. The outer periphery of the pendant handle has 6 scalloped protrusions, which makes it easy for the operator to hold and apply force. The internal thread of the pendant handle matches the external thread of the fixing member 10.
[0050] like Figures 1-2 As shown, the medium transmission assembly 20 includes a first connector 21, and the sealing assembly 30 includes a first seal 31. One side of the first seal 31 abuts against the fixing member 10, and the first connector 21 abuts against the other side of the first seal 31. The fixing member 10 has a first channel 11 inside, the first seal 31 has a second channel 32 inside, and the first connector 21 has a third channel 22 inside. The first channel 11, the second channel 32, and the third channel 22 are connected in sequence.
[0051] During assembly, only the first seal 31 needs to be attached to the fixing member 10 and the first connector 21 needs to be attached to the first seal 31 to complete the initial positioning. Subsequent tightening with the manual operating member 40 will secure it, reducing assembly difficulty. During maintenance, the first seal 31 can be replaced separately by disassembling the first connector 21, without disassembling the entire media transmission assembly 20, improving maintenance convenience.
[0052] Optionally, the first seal 31 is made of polytetrafluoroethylene to ensure sufficient strength and sealing compression.
[0053] In some alternative embodiments, the first seal 31 is provided with an extension 33 on the side facing the fixing member 10, the extension 33 extends into the first channel 11, and a second channel 32 is provided inside the extension 33.
[0054] After the extension 33 extends into the first channel 11, it provides radial positioning for the first seal 31, preventing the first seal 31 from shifting when the manual operating part 40 is tightened. This ensures that the second channel 32 is always coaxially aligned with the first channel 11, and the medium transmission path is stable, preventing a sudden decrease in flow or pressure loss due to component shift.
[0055] like Figure 2 As shown, the first sealing element 31 has a first sealing groove 34 on the side facing the fixing element 10. The sealing assembly 30 also includes a first sealing ring 35, which is disposed within the first sealing groove 34 and abuts against the end of the fixing element 10. The first sealing groove 34 can limit the position of the first sealing ring 35, ensuring that the first sealing ring 35 is always located on the mating end face of the fixing element 10 and the first sealing element 31, thereby improving the sealing performance. At the same time, the first sealing ring 35 can fully fill the tiny gap between the fixing element 10 and the first sealing element 31, significantly improving the sealing effect and preventing media leakage.
[0056] Optionally, the first sealing ring 35 is an O-ring and is made of fluororubber.
[0057] like Figure 2 As shown, the first sealing member 31 has a second sealing groove 36 on the side facing the first connecting member 21. The sealing assembly 30 also includes a second sealing ring 37, which is disposed within the second sealing groove 36 and abuts against the end of the first connecting member 21. The second sealing ring 37 seals the gap between the first connecting member 21 and the first sealing member 31, preventing media leakage.
[0058] It is understandable that the dual sealing effect is achieved by setting the first sealing ring 35 and the second sealing ring 37, thereby improving the sealing performance of the connection device of the vacuum equipment.
[0059] The sealing assembly 30 also includes a second seal 38, which is fitted onto the first connector 21. The manual operating member 40 compresses the second seal 38. Since the manual operating member 40 is fitted onto the outside of the first connector 21, there is a gap of 0.1mm-0.2mm between them. This gap could become a path for external dust to enter or for internal media to leak. The second seal 38 fills this gap. When the manual operating member 40 compresses the second seal 38, the second seal 38 deforms, tightly fitting the inner hole of the manual operating member 40 and the outer wall of the first connector 21, completely sealing the gap and preventing dust from entering or media from leaking.
[0060] The second seal 38 is made of the same material as the first seal 31. That is, the second seal 38 is made of polytetrafluoroethylene (PTFE) to ensure sufficient strength and sealing compression.
[0061] like Figures 1-2 As shown, the media transmission assembly 20 also includes a second connector 23. The outer periphery of the end of the first connector 21 away from the first seal 31 is provided with an external thread, and the second connector 23 is provided with an internal thread. The second connector 23 is screwed to the first connector 21. During assembly, the second connector 23 is screwed to the internal thread of the first connector 21 through the external thread, and the end of the second connector 23 away from the first connector 21 is used to connect with the pipeline of an external water or gas system.
[0062] Vacuum equipment has diverse external water or gas system interface specifications. If the first connector 21 is a fixed interface, the entire first connector 21 needs to be replaced for different external systems, which is costly and inefficient. In this embodiment, the second connector 23 serves as an adapter. The second connector 23 with the corresponding internal thread can be replaced according to the interface specifications of the external water or gas system, thus eliminating the need to replace the first connector 21. This significantly improves the adaptability of the connection device used for vacuum equipment to different external water or gas systems and is compatible with the vast majority of water and gas system interfaces on the market.
[0063] Furthermore, the second connector 23 has a fourth channel 24 inside, which is connected to the third channel 22. After assembly, the fourth channel 24 and the third channel 22 are connected to form a continuous medium transmission channel, which facilitates the inflow and outflow of the medium and reduces flow resistance.
[0064] Optionally, in this embodiment, both the first connector 21 and the second connector 23 are made of metal, such as stainless steel.
[0065] like Figure 3As shown, this embodiment also provides a vacuum device, which includes a furnace body 100, a water-cooled plate 120, and at least one of the aforementioned connecting devices for the vacuum device. The furnace body 100 contains a vacuum chamber 110. The water-cooled plate 120 is disposed within the vacuum chamber 110, and has an inlet and an outlet for the flow of a medium (e.g., cooling water) to control the temperature of the vacuum chamber 110 through medium circulation. The fixing member 10 of the connecting device is fixedly connected to the side wall of the furnace body 100, and the medium transmission component 20 of the connecting device communicates with the inlet or outlet.
[0066] Because the vacuum equipment includes the aforementioned connecting device, disassembly and assembly can be completed simply by rotating the manual operating component 40 during maintenance, improving maintenance efficiency. Disassembly and assembly are dust-free, keeping the vacuum chamber 110 clean at all times and ensuring the quality of the coating process. Simultaneously, there is no risk of hot work, reducing safety hazards and ensuring the long-term safe operation of the vacuum equipment.
[0067] For example, the vacuum equipment may be a neodymium iron boron vacuum coating furnace.
[0068] Preferably, the connection device for the vacuum equipment is configured as two, corresponding to the water inlet and water outlet of the water-cooled plate 120 respectively.
[0069] like Figure 3 As shown, the vacuum equipment also includes a connecting pipe 130. One end of the connecting pipe 130 is connected to a water inlet or outlet, and the other end of the connecting pipe 130 passes through the side wall of the furnace body 100 and is connected to the media transmission assembly 20. The connecting pipe 130 is made of stainless steel. One end of the connecting pipe 130 is connected to the water inlet or outlet of the water-cooled plate 120, and the other end passes through a preset hole in the side wall of the furnace body 100 and extends into the third channel 22 of the first connector 21.
