DETAILED DESCRIPTION

[0030] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In semiconductor manufacturing processes, such as CVD (chemical vapor deposition), PVD (physical vapor deposition), ETCH (etching), etc., water treatment equipment is used to provide water required for operation and process of production equipment or products in the process. Due to the high requirements of equipment (such as equipment accuracy) and product process requirements (such as production environment) in the semiconductor manufacturing field, the water treatment equipment connected to the production equipment is also equipped with a water circulation system to ensure that the production water supplied by the water treatment equipment meets the requirements of semiconductor manufacturing.

[0034] As can be seen from the background technology, during the routine maintenance of water treatment equipment, operators need to disassemble the shell of the water filter for cleaning or replacement. At present, the disassembly and assembly of the water filter shell 40 is performed by operators barehanded, but the manual disassembly and assembly method has low precision, and the structural stability after disassembly and reassembly is poor, which leads to the water filter being prone to leakage and other problems afterwards, and ultimately causing irreversible effects on semiconductor production equipment, semiconductor preparation processes and even product work sites, thereby causing immeasurable property losses to the enterprise. To this end, this embodiment provides the following solution.

[0035] The utility model proposes a disassembly and assembly tool for a water filter housing 40, which is configured to be able to disassemble and assemble the housing of a water filter in a water treatment device. The disassembly and assembly tool replaces the method of disassembling and assembling the water filter housing 40 by hand in the prior art, thereby solving a series of problems caused by the poor structural stability of the water filter housing 40 and the water filter after reassembly.

[0036] Please refer to the attached Figure 1 The disassembly and assembly tool of the water filter housing 40 described in this embodiment includes a support ring 10. The support ring 10 serves as the supporting body of the disassembly and assembly tool. Its overall structure is roughly a closed ring structure. The structure of the support ring 10 can be but is not limited to a circular ring, a rectangular ring, a trapezoidal ring, a triangular ring, a polygonal ring, etc. As for the specific structure of the support ring 10, a disassembly and assembly hole 11 is formed on the inner side of the support ring 10 and is arranged to pass through the support ring 10 along its axial direction. The axial direction of the support ring 10 can generally be understood as the length direction of the component. Of course, the axial direction of the support ring 10 can also be determined by the direction in which the disassembly and assembly hole 11 is located in the support ring 10 and extends.

[0037] According to the basic structure of the support ring 10, it should be understood that, in the process of the disassembly tool disassembling and assembling the water filter housing 40, the support ring 10 can be sleeved on the outer periphery of the water filter housing 40 through the disassembly hole 11, so that the support ring 10 can clamp the water filter housing 40 through the clamping component 20 thereon. It should be noted that, in the process of the disassembly tool disassembling and assembling the water filter housing 40, the disassembly tool is not directly fixed to the water filter housing 40 through the support ring 10, that is, there is no interference fit relationship between the disassembly hole 11 and the water filter housing 40. Specifically, the aperture size of the disassembly hole 11 needs to be set larger than the outer diameter size of the water filter housing 40, so that when the support ring 10 is sleeved on the water filter housing 40, a clearance fit relationship with a certain gap is formed between the hole wall of the disassembly hole 11 and the outer peripheral wall of the water filter housing, so as to facilitate the adjustment of the above-mentioned clamping component 20, and avoid the problem of wedging between the disassembly hole 11 and the water filter housing 40.

[0038] As can be seen from the above, the disassembly hole 11 on the support ring 10 is only used to provide a space for the water filter housing 40 to move through, and there is no direct physical connection between the disassembly hole 11 and the water filter housing 40. In order to enable the disassembly tool to switch between the matching relationship and the non-matching relationship with the water filter housing 40, please continue to refer to the attached Figure 1 The disassembly and assembly tool also includes a plurality of clamping components 20. In this example, the clamping components 20 are movably arranged on the support ring 10, and when the support ring 10 is sleeved on the periphery of the water filter housing 40, each clamping component 20 can move relative to the support ring 10 between positions close to and away from the water filter housing 40. That is to say, when the support ring 10 is not sleeved on the periphery of the water filter housing 40, the clamping components 20 can move in a direction close to the disassembly and assembly hole 11 and in a direction away from the disassembly and assembly hole 11. The clamping member 20 can move relative to the support ring 10 in a direction close to the disassembly hole 11, and can move to a state of being tightly pressed against the outer wall of the water filter housing 40 during the process of disassembling and assembling the water filter housing 40, so that the support ring 10 can form a relatively fixed matching relationship with the water filter housing 40 through the clamping member 20. In order to keep the matching relationship relatively stable and ensure that the support ring 10 will not be relatively displaced in the circumferential direction relative to the water filter housing 40 during the process of disassembling and assembling the water filter housing 40 through the clamping member 20, a plurality of clamping members 20 are arranged at intervals around the support ring 10 so that the support ring 10 can be fixed when it is sleeved on the water filter housing 40. In the case of the filter housing 40, the support ring 10 can be spaced around the outer peripheral wall of the water filter housing 40 by a plurality of clamping parts 20, and the support ring 10 clamps and fixes the water filter housing 40 in a roughly annular clamping manner by the clamping parts 20. In this way, when each clamping part 20 is adjusted to a state of pressing against the water filter housing 40, the support ring 10 and the water filter housing 40 can maintain a relatively stable matching relationship, avoiding the support ring 10 tilting relative to the water filter housing 40 or stress concentration on the water filter housing 40 and other related problems that affect the matching stability of the support ring 10 and the water filter housing 40. Figure 1As shown, in the axial direction of the support ring 10, the projection of at least part of the clamping component 20 is located in the disassembly hole 11, and the clamping component 20 remains at least partially located in the disassembly hole 11, which can ensure that the clamping component 20 and the support ring 10 have a relatively stable matching relationship. In the process of the support ring 10 being sleeved on the water filter housing 40, or in the process of the support ring 10 being removed from the water filter housing 40, it can also be ensured that the part of the disassembly tool that first contacts the water filter housing 40 is the clamping component 20, thereby avoiding the situation where the support ring 10 directly contacts the water filter housing 40, resulting in the inability to adjust the clamping component 20, and ultimately failing to form a matching relationship with the water filter housing 40 and failing to disassemble it, and also plays a good protective role for the shell surface of the water filter housing 40.

[0039] Continuing with the above embodiment, each clamping component 20 can move relative to the support ring 10 to adjust the size of the projection of the clamping component 20 in the disassembly hole 11. By independently adjusting the relative position of each clamping component 20 on the support ring 10, each clamping component 20 is adjusted to a state where they are all tightly matched with the outer wall surface of the water filter housing 40, so as to achieve relative fixation of the support ring 10 and the water filter housing 40, so that the disassembly tool can be suitable for water filter housings 40 of different specifications (including different sizes and structures), thereby improving the versatility of the disassembly tool. Conversely, when the support ring 10 is relatively fixed to the water filter housing 40 through multiple clamping components 20, each clamping component 20 can also be adjusted to be separated from the surface of the water filter housing 40, so that the support ring 10 can be disassembled from the water filter housing 40, thereby protecting the surface of the water filter housing 40 well and preventing the water filter housing 40 from being damaged during the process of matching or disengaging with the disassembly tool.

[0040] Based on the implementation method in which the projection of the clamping component 20 in the axial direction of the support ring 10 is at least partially located in the disassembly hole 11, in one embodiment, the clamping component 20 can be set to a structural form built into the support ring 10. Specifically, the interior of the support ring 10 is provided with a guide structure (such as through holes, threaded holes, etc. of various cross-sectional shapes) opened along its inner and outer directions (from the inner ring wall to the outer ring wall of the support ring 10). The guide structure can provide a position for the clamping component 20 to be installed, and can also form a corresponding active matching relationship with the clamping component 20, requiring a main body The movable fitting relationship not only requires the clamping component 20 to be able to make relative movement along the inward and outward directions of the support ring 10 within the guide structure, but also requires the clamping component 20 to be self-locked on the support ring 10 through the guide structure. Since the clamping component 20 can be self-locked on the support ring 10, under a certain external force, the clamping component 20 will not move relative to the support ring 10, thereby ensuring that the disassembly and assembly tool maintains a relatively stable positional relationship with the water filter housing 40 when clamping the water filter housing 40 through the clamping component 20 and will not detach from the water filter housing 40.

[0041] In another embodiment, the clamping component 20 may also be arranged on the outside of the support ring 10. In this embodiment, the support ring 10 is formed with a guide structure for providing movable installation of the clamp along at least one side of its axial direction. The clamping component 20 is similar to the above structure and is installed on the guide structure to be arranged side by side with the support ring 10 in its axial direction. Similarly, the clamping component 20 can be located in the guide structure and move relative to the support ring 10 along the inner and outer directions of the support ring 10. At the same time, the clamping component 20 also needs to achieve self-locking between the guide structure and the support ring 10.

[0042] In order to facilitate the disassembly and assembly of the water filter housing 40, the disassembly and assembly tool is further fixedly provided with a handle 30 on the outer side of the support ring 10 in this embodiment. For example, the handle 30 can be provided as a structural form extending from the support ring 10 in a direction away from the disassembly and assembly hole 11. In the process of disassembling and assembling the water filter housing 40, that is, when the support ring 10 is clamped to the outer wall surface of the water filter housing 40 by the clamping component 20, the operator can apply a force in the circumferential direction to the support ring 10 by holding the handle 30. In this state, the handle 30 is located on the support ring 10 to form a powerful arm, so that the support ring 10 can apply a relatively stable torque in the circumferential direction to the water filter housing 40 through a plurality of clamping components 20, and finally achieve stable disassembly and installation between the water filter housing 40 and the water filter.

[0043] Through the technical solution provided above, the disassembly and assembly tool is used to disassemble and assemble the water filter. Compared with the manual operation, the respective adjustment of the multiple clamping parts 20 can be suitable for water filter housings 40 of different sizes and structures. Each clamping part 20 can be adjusted accordingly in the inner and outer directions of the support ring 10 according to the structural form of the corresponding water filter housing 40, so that the disassembly and assembly tool can maintain a stable matching state with the water filter housings 40 of different specifications during the process of disassembling and assembling the water filter housings 40. The multiple clamping parts 20 cooperate to clamp the water filter housing 40, and the support ring 10 and the water filter can be stably matched. The force between the shells 40 is more even, so that the rotation of the water filter shell 40 during the assembly and disassembly process is more stable and balanced, and the assembly position of the water filter shell 40 on the water treatment equipment is more precise, ensuring that after the water filter shell 40 is reassembled on the water treatment equipment, the assembly relationship between the water filter shell 40 and the water treatment equipment meets the assembly requirements, avoiding leakage at the assembly point between the water filter shell 40 and the water treatment equipment, and avoiding the impact of leakage of water treatment equipment on semiconductor production equipment, semiconductor preparation process and even product work site, thereby reducing the risk of property loss to the enterprise.

[0044] In addition, the operator applies a circumferential rotational force to the support ring 10 through the handle 30, which is more labor-saving than the manual disassembly and assembly method, reduces the difficulty of disassembly and assembly of the water filter, and improves the inspection and maintenance efficiency of the water filter.

[0045] It is worth mentioning that the water filter housing 40 of this embodiment is as follows Figure 2 As shown, it is a generally barrel-shaped structure, and one end thereof located at the opening is provided with an external thread structure 41 for threaded connection with a water filter.

[0046] As a refinement of the arrangement of the clamping components 20 on the support ring 10 in the above embodiment, in this embodiment, the spacing between any two adjacent clamping components 20 is equal, so that when the support ring 10 is clamped on the outer periphery of the water filter housing 40 by multiple clamping components 20, the interaction force between the support ring 10 and the water filter housing 40 can be balanced, avoiding the situation where some clamping components 20 are located on the outside of the water filter housing 40 to cause stress concentration and cause damage to the water filter housing 40. While ensuring the relative balance between the support ring 10 and the water filter housing 40, the force on the water filter housing 40 is more uniform, further improving the stability of the water filter housing 40 during the disassembly and assembly process.

[0047] Please refer to the attached Figure 1In any of the above embodiments, a structural form of a clamping component 20 is provided so that the clamping component 20 has the above-mentioned adjustment and self-locking functions. Specifically, the clamping component 20 includes an operating portion 21, a matching portion 22 and a clamping portion 23 which are arranged in sequence from the outside of the support ring 10 to the inside. Among them, the operating part 21 is arranged on the outer side of the support ring 10, and is used to provide an operating position for the clamping component 20 to be movable and adjusted relative to the support ring 10. The operator can push and pull the operating part 21 along the inner and outer directions of the support ring 10, twist it circumferentially around the clamping component 20, and other operating methods, thereby driving the clamping component 20 to move and adjust relative to the support ring 10 along the inner and outer directions. The operating part 21 can be set with a corresponding operating structure according to the adjustment method of the clamping component 20 on the support ring 10. For example, in the case where the clamping component 20 is operated by pushing and pulling, the operating part 21 can be set to a structure for providing the operator's hand to push and pull, such as providing a push plate for hand pushing and a pull ring for hand pulling; and in the case where the clamping component 20 is operated by twisting, the operating part 21 can be set to a structure such as a bolt head for providing a twisting operation. The first end of the matching portion 22 is connected to the operating portion 21 on the basis of the movable matching with the support ring 10 along the inner and outer directions of the support ring 10, and the matching portion 22 is adaptively adjusted in structure according to the operation mode of the clamping component 20 on the support ring 10. For example, the matching portion 22 can be set as a light rod suitable for sliding in a structure such as a slide groove or a through hole, or set as a structure such as a screw rod that realizes axial displacement by twisting. According to the structure between the matching portion 22 and the support ring 10, the clamping component 20 can be self-locked on the support ring 10 through the matching portion 22. The support ring 10 can wedge the matching portion 22 through the through hole or slide groove set inside it, or the matching portion 22 is provided with a matching threaded hole structure to realize the above self-locking function. The clamping portion 23 is connected to the second end of the matching portion 22. When the clamping component 20 is installed on the support ring 10, the clamping portion 23 is kept in the disassembly hole 11, and is used to press the water filter housing 40 during the disassembly and assembly process of the water filter housing 40.

[0048] Through the above-mentioned arrangement of the clamping component 20, the operator can easily adjust and control the clamping component 20 through the operating part 21 placed on the outside of the support ring 10, and the matching part 22 can ensure the stable matching between the clamping component 20 and the support ring 10, so as to ensure that the clamping component 20 can move in the inner and outer directions relative to the support ring 10 while maintaining a self-locking state on the support ring 10 in the absence of external force, and the clamping part 23 can be designed as a relatively smooth structural form to prevent the clamping part 23 from damaging the water filter housing 40 or scratching the water filter housing 40 when the clamping component 20 is pressed against the water filter housing 40 through the clamping part 23.

[0049] On the basis of any of the above embodiments, a buffer structure is provided at one end of the clamping component 20 located in the disassembly hole 11. For example, in the embodiment in which the clamping component 20 includes an operating portion 21, a matching portion 22 and a clamping portion 23 arranged in sequence, a buffer structure can be provided on the clamping portion 23, or the buffer structure can be used as the clamping portion 23 of the clamping component 20. The buffer structure can reduce the impact force between the clamping component 20 and the water filter housing 40. When the clamping component 20 is pressed against the water filter housing 40, the buffer structure can be in a compressed state and increase the pre-tightening force of the clamping component 20 on the water filter housing 40, so that the clamping force between the support ring 10 and the water filter housing 40 is greater, and the matching stability between the support ring 10 and the water filter housing 40 is improved.

[0050] It is understandable that the buffer structure can be made of a material with a certain flexibility and elastic reset properties, so that when it is in a compressed state, it can increase the clamping force between the clamping component 20 and the water filter housing 40 while providing effective protection for the surface of the water filter housing 40.

[0051] In one embodiment, the buffer structure is made of rubber material. Of course, the buffer structure can also be made of other flexible materials with elastic restoring properties such as leather, silicone, etc.

[0052] In other embodiments, the buffer structure can also be set as an arc-shaped pressure plate, which is located in the disassembly hole 11. In the axial direction of the support ring 10, the arc-shaped pressure plate is recessed outward from its two pairs of ends toward the middle, so that when multiple arc-shaped pressure plates are arranged around the disassembly hole 11, the connecting lines between the multiple arc-shaped pressure plates form a structure that is approximately circular, so as to adapt to the peripheral structure of the water filter housing 40. Of course, the above-mentioned rubber, silicone, leather and other materials with buffering function can also be set on the side of the arc-shaped pressure plate away from the support ring 10.

[0053] Please continue to refer to the attached Figure 1 As a specific structural form of the clamping component 20, the clamping component 20 of this embodiment is an adjusting bolt, wherein the screw head of the adjusting bolt is the operating portion 21, the screw rod of the adjusting bolt is the matching portion 22, and the clamping portion 23 is formed at the end of the screw rod of the adjusting bolt away from the screw head. In the embodiment in which the clamping component 20 is provided with a buffer structure, the buffer structure is provided at the end of the screw rod of the adjusting bolt, and in the embodiment in which the buffer structure is rubber, the rubber can be connected to the end of the screw rod of the adjusting bolt by at least partially covering or bonding, so as to avoid the situation in which the screw rod of the adjusting bolt directly presses against the water filter housing 40.

[0054] Correspondingly, the support ring 10 is provided with a plurality of threaded holes spaced around its circumference, the threaded holes are provided through both inner and outer sides of the support ring 10, and the adjusting bolts are threadedly matched with the threaded holes through their screw rods.

[0055] In the above-mentioned manner, the operator can use a tool such as a screwdriver to twist the screw head of the adjusting bolt, so that the screw head of the adjusting bolt as the operating part 21 can drive the adjusting bolt screw rod as the matching part 22 and the clamping part 23 to rotate around its own rotation axis in the threaded hole located in the support ring 10 under the operation of the screwdriver and other tools, and during its rotation, it further extends into the disassembly hole 11 along the direction in which the threaded hole extends (inside and outside directions of the support ring 10) or moves in the direction of retracting into the threaded hole. The threaded connection relationship between the threaded rod and the threaded hole can enable the clamping component 20 to be located on the support ring 10 to achieve stable self-locking. While the operation is simple, the clamping component 20 and the support ring 10 can maintain a relatively stable state.

[0056] As an embodiment of the structure of the support ring 10, the support ring 10 includes a plurality of support plates 12, and the plurality of support plates 12 are sequentially connected to enclose a disassembly hole 11, so that in the axial direction of the support ring 10, the support ring 10 is a polygonal structure, and on the basis of this structure, at least one clamping component 20 is respectively provided on each support plate 12. The arrangement of one support plate 12 corresponding to one clamping component 20 can facilitate the disassembly and assembly of the support component on the support ring 10, and the relatively straight structure can make it easier to assemble and disassemble the clamping component 20 on the corresponding support plate 12. In addition, the support ring 10 with a polygonal structure can make it easier for the user to hold the support ring 10, which is beneficial for the operator to lift the support ring 10 and facilitate the alignment, assembly and disassembly operations between the support ring 10 and the water filter housing 40.

[0057] On the basis of any of the above embodiments, the handles 30 of the disassembly and assembly tool can be set to at least two, at least two handles 30 are arranged at intervals around the support ring 10, and the spacing between any two adjacent handles 30 is equal. Exemplarily, in the case of two handles 30, the two handles 30 are respectively arranged on opposite sides of the support ring 10; in the case of three handles 30, the three handles 30 are arranged in an equilateral triangle on the outer periphery of the support ring 10; and in the case of four handles 30, the four handles 30 are arranged in a square on the outer periphery of the support ring 10. Of course, the number of handles 30 can be set to a larger number according to actual operation requirements, as long as it is ensured that multiple handles 30 are evenly arranged on the support ring 10, so that when the operator applies a circumferential rotation force to the support ring 10 through the handle 30, the force is applied to the support ring 10 in a balanced manner, which can make the rotation of the water filter housing 40 on the water filter more stable, and also make the assembly structure between the water filter housing 40 and the water filter more compact when the water filter housing 40 is tightened on the water filter.

[0058] In addition, providing a plurality of handles 30 on the support ring 10 can also provide the operator with more operating positions. For example, when there are two handles 30, if the position of one of the handles 30 is not convenient for the operator to operate, the operator can apply a circumferential force to the support ring 10 through the other handle 30 opposite to the operator, and when the other handle 30 is rotated to a position that is not conducive to the operator's operation, the operator can alternately operate the support ring 10 through the first hand.

[0059] Please continue to refer to the attached Figure 1 According to any of the above embodiments, in order to allow the support ring 10 to form a sleeve relationship with the water filter housing under different conditions such as different operating scenarios and different equipment structures, the support ring 10 of this embodiment is set as a split structure. Specifically, the support ring 10 in this embodiment includes an upper ring portion 13 and a lower ring portion 14. The upper ring portion 13 and the lower ring portion 14 enclose a disassembly hole 11. The lower ring portion 14 is hingedly matched with one end of the upper ring portion 13, and the lower ring portion 14 is locked with the other end of the upper ring portion 13 through a locking mechanism 15 to meet the opening and closing action of the support ring 10. For example, the locking mechanism 15 may include through holes respectively opened with the upper ring portion 13 and the lower ring portion 14, and bolts and nuts that can be inserted into the above through holes.

[0060] By setting the support ring 10 as a split structure of the upper ring part 13 and the lower ring part 14 as mentioned above, the support ring 10 can adapt to different working scenarios and working requirements. Specifically, in some working scenarios, the operator can complete the cooperation between the support ring 10 and the water filter housing 40 without disassembling the upper ring part 13 and the lower ring part 14, while in other working scenarios, the operator can disassemble one end of the upper ring part 13 and the lower ring part 14 through the locking mechanism 15, so that the upper ring part 13 and the lower ring part 14 are swung away from each other through the hinge between the two to separate. At this time, an opening is formed on one side of the disassembly hole 11, and the shell of the water filter can enter the disassembly hole 11 through the opening. Subsequently, the operator operates the support ring 10 to allow the upper ring part 13 and the lower ring part 14 to swing towards each other around the hinge between the two to a state of being surrounded by the water filter housing 40 and locked by the locking mechanism 15, and then further adjusts the clamping component 20.

[0061] On the contrary, during the disassembly process of the disassembly tool and the water filter housing 40, the operator can unlock the locking mechanism 15 to lock the upper ring portion 13 and the lower ring portion 14, so that the upper ring portion 13 and the lower ring portion 14 can move away from each other around the hinge between the two until the water filter housing 40 can be separated from the support ring 10 from the opening between the two, and finally, the support ring 10 is removed from the water filter housing 40.

[0062] According to the split support ring 10 structure, the hinged joint of the upper ring portion 13 and the lower ring portion 14 is located at the connection between the support ring 10 and the handle 30, which facilitates the operator to operate the upper ring portion 13 and the lower ring portion 14. In the embodiment where there are multiple handles 30, the hinged joint is located at the connection between one of the handles 30 and the support ring 10.

[0063] In summary, the disassembly and assembly tool provided in this embodiment can be suitable for water filter housings 40 with different structural forms through multiple clamping parts 20, and can allow operators to disassemble and assemble the water filter housing 40 more easily and smoothly, thereby preventing the water filter housing 40 from leaking after disassembly and reassembling, thereby meeting the watertight requirements of the water filter.
