Description

Technical Field

[0001] This application relates to the field of equipment maintenance technology, and in particular to an apparatus for disassembling valve bodies. Background Technology

[0002] Chemical vapor deposition (CVD) is a common method for manufacturing semiconductors. This process can be used to deposit various types of materials, including insulators, semiconductors, and conductors.

[0003] Chemical vapor deposition (CVD) equipment deposits thin films on wafer surfaces by heating precursor gases within a chamber and utilizing their thermal dissociation and chemical reaction. Simultaneously, to achieve high-speed deposition at low temperatures, CVD equipment utilizes plasma enhancement technology, which uses an electric field to excite the precursor gases to form plasma at low temperatures, thereby improving deposition efficiency.

[0004] During the process, the precursor gas needs to be controlled to enter the chamber through the valve body. Over prolonged operation, the internal components of the valve body are susceptible to gas corrosion, leading to performance degradation. When a problem occurs, workers need to disassemble the valve body, remove the damaged parts for maintenance, and perform servicing on the remaining components. Due to the high degree of integration in the valve body's structure, manual disassembly and assembly is difficult, time-consuming, and labor-intensive. If disassembly and repair are not performed, and a new valve body is directly replaced, this increases replacement costs.

[0005] Therefore, how to provide a tool that facilitates the disassembly of the valve body is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] As described in the background section, during the process, the precursor gas needs to be controlled to enter the chamber through a valve body. Over long-term operation, the internal components of the valve body are susceptible to gas corrosion and mechanical wear, leading to performance degradation. When a problem occurs with the valve body, operators need to disassemble it, remove the damaged components for maintenance, and perform servicing on the remaining parts. Due to the high degree of integration in the valve body's structure, manual disassembly and assembly are difficult, time-consuming, and labor-intensive. If disassembly and repair are not performed, and a new valve body is directly replaced, this increases replacement costs.

[0023] Based on this, the present application aims to provide a device for disassembling valve bodies to solve the technical problem of cumbersome disassembly in the prior art.

[0024] The embodiments of this application will be analyzed in detail below with reference to the accompanying drawings.

[0025] refer to Figure 1 and Figure 2The valve body 1 includes an outer shell 10, a first plug 11 and a second plug 12 respectively sealing the control end and the air outlet end of the outer shell 10, and a first piston 13 and a second piston 14 disposed inside the outer shell 10. The first plug 11, the first piston 13, the second piston 14 and the second plug 12 are arranged sequentially along the length direction of the outer shell 10.

[0026] The valve body 1 is cylindrical; when the valve body 1 is working, the precursor gas flows in from the control end, flows through the first plug 11, the first piston 13, the second piston 14 and the second plug 12 and then flows out from the outlet end.

[0027] refer to Figures 1 to 6 An apparatus for disassembling a valve body includes: a base 2 with a fixing hole 20 for fixing the air outlet end of a housing 10; a top component 3 with a first hole 30 and a second hole 31 of different diameters; a first disassembly component 4 matching the first hole 30, passing through the first hole 30 and threadedly connected to a first plug 11, the first disassembly component 4 being screwed into the first plug 11 to move the first plug 11 away from the control end of the housing 10; and a second disassembly component 5 matching the second hole 31, after the first plug 11 and the first piston 13 are removed, the second disassembly component 5 passing through the second hole 31, extending from the control end of the housing 10 into the interior of the housing 10 and abutting against a second piston 14, the second disassembly component 5 being used to push the second piston 14 so that both the second piston 14 and the second plug 12 fall off from the air outlet end of the housing 10.

[0028] The fixing hole 20 holds the columnar valve body 1 upright on the base 2 for subsequent disassembly. The first hole 30 and the second hole 31 on the top component 3 provide positioning guidance for the use of the first disassembly component 4 and the second disassembly component 5, respectively.

[0029] As a specific implementation method, refer to Figure 4 The longitudinal depth of the fixing hole 20 is greater than the length of the air outlet end of the outer casing 10, and the second piston 14 and the second plug 12 can pass through the fixing hole 20.

[0030] As an example of disassembling the first plug 11 and the first piston 13, refer to Figures 3 to 5The operator fixes the valve body 1 to the base 2, aligns the first hole 30 of the top component 3 with the center of the first plug 11, passes the first disassembly piece 4 through the first hole 30 and threadedly connects the first disassembly piece 4 to the first plug 11. Since the air outlet of the valve body 1 is fixed in the fixed hole 20, the operator only needs to rotate the first disassembly piece 4 to move the first plug 11, which is threadedly engaged with the first disassembly piece 4, away from the control end along the thread to detach it from the housing 10. After removing the top component 3, the operator removes the first plug 11 from the first disassembly piece 4 and then removes the first piston 13 located inside the housing 10. The first piston 13 is movably installed in the housing 10, thus achieving the disassembly of the first plug 11 and the first piston 13.

[0031] As an example of disassembling the second plug 12 and the second piston 14, refer to Figures 6 to 8 The worker reinstalls the top component 3, aligning the second hole 31 of the top component 3 with the center of the second piston 14. The second disassembly piece 5 is then passed through the second hole 31 and inserted into the housing 10 to abut against the second piston 14. Since the fixing hole 20 is a through hole, the worker only needs to push the second disassembly piece 5 to transmit the thrust to the second piston 14 and the second plug 12, causing the second piston 14 and the second plug 12 to detach from the housing 10 and slide down the fixing hole 20 onto the worktable. This completes the disassembly of the second plug 12 and the second piston 14.

[0032] As a specific implementation method, refer to Figure 4 and Figure 7 The first hole 30 matches the diameter of the first disassembly part 4, and the second hole 31 matches the diameter of the second disassembly part 5. This arrangement ensures that the first disassembly part 4 is limited by the first hole 30 during rotation, and the second disassembly part 5 is limited by the second hole 31 during pushing. Neither of them is prone to tilting or shifting during their respective movements, thus ensuring the stability of the disassembly process.

[0033] As a specific implementation method, refer to Figure 4 and Figure 7 The main body of the first plug 11 is a flat disc-shaped structure, and the main body of the second piston 14 is a long strip-shaped structure. The shape and diameter of the first plug 11 are larger than the shape and diameter of the second piston 14. The diameter of the first hole 30 is larger than the diameter of the second hole 31. The diameter of the first disassembly part 4 is larger than the diameter of the second disassembly part 5.

[0034] In summary, by using the threaded engagement between the first disassembly piece 4 and the first plug 11 at the first hole 30, the first plug 11 can be removed, and the first piston 13 can be taken out. Then, by using the second disassembly piece 5 at the second hole 31, the second piston 14 and the second plug 12 can be pushed out. This achieves the disassembly of the valve body 1. The operation is simple, time-saving, and labor-saving, and also avoids the high cost problem caused by directly replacing the valve body without maintenance.

[0035] As a preferred embodiment, refer to Figures 3 to 5 The first disassembly component 4 includes a threaded rod, and the end of the first plug 11 away from the first piston 13 has a threaded hole 110, and the threaded rod matches the threaded hole 110.

[0036] As an example, the worker passes the threaded rod through the first hole 30 so that the threaded end of the threaded rod abuts against the top of the threaded hole 110. The threaded rod is rotated so that the threaded end is screwed into the threaded hole 110. At the same time, the first plug 11 moves along the thread in a direction away from the first piston 13 so as to disengage from the control end of the housing 10. When the relative movement between the threaded rod and the first plug 11 ends, the tail end of the threaded rod abuts against the top surface of the top component 3, and the threaded end is connected to the first plug 11.

[0037] As an optional implementation, the second disassembly member 5 includes a push rod that extends from the control end of the housing 10 through the second hole 31 into the interior of the housing 10 and abuts against the end of the second piston 14.

[0038] In this process, the thrust is transmitted to the second piston 14 and the second plug 12 by means of a single push rod, causing them to fall off from the air outlet of the outer casing 10.

[0039] As a preferred embodiment, refer to Figures 6 to 8 The second piston 14 includes a piston rod, and the piston rod has a protrusion at one end near the second plug 12. The second disassembly component 5 includes an abutment rod 50 and a hollow rod 51. One end of the hollow rod 51 extends from the control end of the housing 10 into the interior of the housing 10, is sleeved on the outer periphery of the piston rod and abuts against the protrusion, and the other end abuts against the abutment rod 50 provided through the second hole 31.

[0040] Since the piston rod (i.e. the main body of the second piston 14) has a long and thin strip structure, one end of the hollow rod 51 is fitted around the outer periphery of the piston rod to perfectly match the shape of the piston rod. Then, with the push of the abutment rod 50, the thrust is transmitted to the second piston 14 and the second plug 12.

[0041] As an example, after the worker removes the first plug 11 and the first piston 13, the hollow rod 51 is inserted into the outer casing 10 and fitted onto the second piston 14. Then, the abutment rod 50 is passed through the second hole 31, so that the abutment rod 50 abuts against the end of the hollow rod 51 away from the second piston 14. Pushing the abutment rod 50, the hollow rod 51 transmits the thrust to the second piston 14 and the second plug 12, causing them to detach from the air outlet of the outer casing 10 and slide down the fixing hole 20 onto the worktable. In some cases, if the hollow rod 51 is too tightly connected to the second piston 14, it may detach from the outer casing 10 along with the second piston 14 and slide down the fixing hole 20.

[0042] As a preferred embodiment, refer to Figures 3 to 8 The appliance also includes a support component 6, which is connected between the base 2 and the top component 3 to support the top component 3.

[0043] As a preferred embodiment, refer to Figure 3 and Figure 6 There are two support components 6. The two support components 6 are located at two opposite corners of the base 2, and the valve body 1 is located between the two support components 6. The two support components 6 and the valve body 1 are all located on the same diagonal line of the base 2. The arrangement of the support components 6 provides two fulcrums for the top component 3, so that the balance of the top component 3 will not be affected by excessive movements when the operator performs disassembly, thus ensuring the safety of the operation.

[0044] As a preferred embodiment, refer to Figures 3 to 8 The support component 6 includes a fixed rod 60 and a support column 61. The base 2 also has a connection hole 21, and the top component 3 also has a support hole 32. One end of the support column 61 is connected to the connection hole 21, and the other end is connected to the fixed rod 60 that passes through the support hole 32.

[0045] Among them, the support column 61 serves to separate the base 2 from the top component 3, and the cooperation between the fixing rod 60 and the support column 61 realizes the limiting and fixing of the top component 3 by the support component 6.

[0046] In a preferred embodiment, one end of the support column 61 is provided with a connecting structure 610, which is engaged in the connecting hole 21, and the other end is provided with a channel structure 620. The fixing rod 60 passes through the support hole 32 and is tightly fitted in the channel structure 620, so that the top component 3 abuts against the end face of the support column 61.

[0047] The connecting structure 610 is formed by extending outward from one end of the support column 61, and the channel structure 620 is formed by recessing inward from the other end of the support column 61. The insertion and engagement of the connecting structure 610 with the connecting hole 21 and the insertion and engagement of the fixing rod 60 with the channel structure 620 make the support component 6 stably connected between the base 2 and the top component 3, so as to achieve a good support effect for the top component 3.

[0048] As a preferred embodiment, refer to Figures 3 to 8 The first hole 30, the second hole 31 and the support hole 32 are arranged along the length of the top component 3.

[0049] As an example, with Figure 3 and Figure 6 Based on the perspective, and referencing Figures 3 to 8 The top component 3 has six holes arranged sequentially from left to right along its length: a first support hole, a second support hole, a first hole 30, a second hole 31, a third support hole, and a fourth support hole. The first hole 30 is for the passage of the first disassembly member 4, the second hole 31 is for the passage of the second disassembly member 5, and the first to fourth support holes are for connecting the support assembly 6. (Reference) Figure 3 Two support components 6 are respectively connected to the first support hole and the third support hole. The worker uses the first disassembly piece 4 to remove the first plug 11, loosens the fixing rod 60 and removes the top component 3, removes the first plug 11 from the first disassembly piece 4, and then removes the first piston 13 from the outer casing 10. This completes the disassembly of the first plug 11 and the first piston 13. Then refer to... Figure 4 The worker moves the top component 3 one hole to the left, aligning the second hole 31 with the valve body 1. The two fixing rods 60 are then passed through the second and fourth support holes respectively and connected to the corresponding support columns 61 to achieve locking support of the support component 6. Then, the second disassembly component 5 is used to push the second piston 14 and the second plug 12, causing the second piston 14 and the second plug 12 to fall out of the outer shell 10 and slide down the fixing hole 20 onto the worktable. This completes the disassembly of the second plug 12 and the second piston 14, thus completing the entire valve body 1 disassembly process.
