Description

Technical Field

[0001] The present application relates to the field of production and manufacturing technology, and in particular to an assembly device. Background Art

[0002] During the assembly of core components of semiconductor valves, due to the requirements of semiconductor valves, various special-shaped grooves on the valve core with openings smaller than the inner cavity, such as dovetail grooves, cannot be lubricated when assembled with the sealing ring, and must be assembled manually. The small opening of the special-shaped groove requires compression and extrusion of the sealing ring during assembly. Due to factors such as unstable force direction and uneven pressure during manual assembly, the sealing ring is prone to scratches, cracks, tears, distortion, uneven expansion and contraction, and even falling off during assembly. This results in high labor costs during assembly. In addition, the sealing effect of the sealing ring in the special-shaped groove is unstable, which cannot meet the current assembly requirements of semiconductor valves. Utility Model Content

[0003] In view of this, an object of the embodiments of the present application is to provide an assembly device to improve the problem of poor sealing ring assembly effect in the prior art.

[0004] In order to solve the above problems, in a first aspect, an embodiment of the present application provides an assembly device, the assembly device comprising: a driving member, a motion assembly, a positioning member, a guide member and a base;

[0005] The guide member is fixed on the base;

[0006] The guide member and the positioning member are sleeved on the periphery of the motion component, and the outer wall of the motion component, the inner wall of the positioning member and the top wall of the guide member away from the base form a placement groove for placing the sealing member;

[0007] The first end of the motion component and the groove area of ​​the positioning member form a placement area for the part to be assembled; the second end of the motion component is elastically connected to the base; wherein, the part to be assembled is provided with a special-shaped groove, the size of the first opening of the special-shaped groove is smaller than the size of the interior of the groove body, and the placement groove corresponds to the position of the special-shaped groove;

[0008] The driving member is used to provide pressure in the assembly direction for the part to be assembled, the positioning member and the moving assembly drive the part to be assembled to move based on the pressure, and the guide member pushes the seal into the special-shaped groove based on the fixed connection with the base; wherein, the assembly direction is perpendicular to the placement plane of the part to be assembled and points to the direction of the base.

[0009] In the above implementation process, corresponding placement grooves are formed by the provided guide members, positioning members and moving components, so that during assembly, the placement grooves accommodate and place the seal to be assembled, and the position of the placement grooves corresponds to the position of the special-shaped grooves on the part to be assembled placed on the moving component, so that the special-shaped grooves and the seal are statically aligned for assembly. During assembly, the driving member provides pressure to the part to be assembled in the assembly direction of the base, so that the positioning member and the moving component drive the part to be assembled to move under the action of pressure, and because the guide member is fixedly connected to the base, the bottom of the placement groove remains stationary, that is, during the movement of the moving component and the positioning member, the guide member can keep the seal stationary, so that the stationary seal and the moving part to be assembled generate relative movement, and the seal is pushed into the special-shaped groove on the part to be assembled to realize automatic assembly of the seal, effectively improving the efficiency during assembly and reducing the labor costs such as time and energy required for manual assembly. Moreover, during assembly, the pressure received by the seal and the parts to be assembled is stable and uniform, which effectively reduces the adverse conditions such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off of the seal caused by uneven force, optimizes the assembly effect of the seal, and thus optimizes the sealing effect of the seal in the special-shaped groove, which can meet the assembly requirements of various types of semiconductor valves currently available.

[0010] Optionally, the motion assembly includes a piston member, a connecting member and an elastic member;

[0011] The guide member and the positioning member are sleeved on the outer wall of the piston member;

[0012] The first end of the piston member is used to place the part to be assembled, the second end of the piston member is connected to the first end of the connecting member, and the second end of the connecting member is fixed to the base;

[0013] The elastic member is sleeved on the outside of the connecting member, the first end of the elastic member is connected to the second end of the piston member, and the second end of the elastic member is fixed on the base.

[0014] In the above implementation process, considering that the motion component needs to be restored to its original position after assembly is completed and wait for the next assembly process, in order to achieve automatic resetting, the motion component can be elastically connected to the base. The motion component may include a piston component for placing the parts to be assembled, and a connecting member and an elastic member that are elastically connected to the base. The piston component, the guide component and the positioning component serve as three wall ends respectively, forming a placement groove with an open end. The second end of the piston component is elastically connected to the base through a connecting member and an elastic member sleeved on the outside of the connecting member. By connecting the piston component, the connecting member and the elastic member with the external guide component, positioning component, base and other structures, elastic movement in the corresponding assembly direction and elastic resetting movement after assembly are achieved, thereby realizing the automatic assembly function and effectively improving the efficiency and stability during assembly.

[0015] Optionally, the piston member includes a fixing member, a first piston structure and a second piston structure;

[0016] The first piston structure and the second piston structure are fastened together by the fixing member;

[0017] The first piston structure is used to place the part to be assembled;

[0018] The second piston structure is connected to the connecting member and the elastic member.

[0019] In the above implementation process, considering the piston's kinematic characteristics and to reduce the difficulty of manufacturing the piston, the piston can be split into two piston structures, which are fastened together by corresponding fixings to achieve synchronous movement. The first piston structure is used to hold the part to be assembled, while the second piston structure is used to connect with the connecting member and elastic member to secure the part to be assembled and achieve an elastic connection with the base. This assembly structure can reduce the difficulty of manufacturing the integrated piston, effectively improving the structural accuracy and stability of the piston during movement.

[0020] Optionally, the guide member is provided with n movement grooves, where n is a positive integer greater than or equal to 2;

[0021] The outer wall of the piston is provided with n protrusion structures;

[0022] The protruding structure is configured to pass through the movement slot;

[0023] The piston member moves in the movement groove based on the protrusion structure.

[0024] In the above implementation process, in order to allow the guide member to be sleeved on the outside of the piston member so as to limit the movement of the piston member in the assembly direction through the guide member, a plurality of movement grooves can be provided on the guide member, and a plurality of corresponding protrusion structures can be provided on the outer wall of the piston member. The protrusion structure passes through the movement groove provided on the guide member so as to sleeve the guide member on the outer wall of the piston member. During the movement of the moving assembly, the guide member can provide the protrusion structure with a corresponding movement space in the assembly direction based on the movement groove provided thereon, so as to limit the movement direction of the piston member. Moreover, in the movement space provided by the movement groove, the guide member can also be in a stationary state during the movement of the moving assembly, effectively reducing the impact of the movement of the moving assembly on the guide member, further improving the stability of the guide member, and thus improving the stability of the seal placed on the guide member.

[0025] Optionally, in the assembly direction, the first length of the movement groove is greater than the second length of the protruding structure;

[0026] The length difference between the first length and the second length is set based on an outer diameter parameter of the seal;

[0027] On a placement plane perpendicular to the assembly direction, a first gap distance is provided between an outer wall of the piston element and an inner wall of the guide element.

[0028] In the above implementation process, during the movement of the moving component, the protruding structure will reciprocate along the assembly direction. Therefore, in the assembly direction, in order to enable the protruding structure to achieve smooth movement in the movement groove on the guide member, the first length of the movement groove can be set to be greater than the second length of the protruding structure, and the first length can be set according to the outer diameter parameter of the seal, that is, the advancement distance can be determined according to the actual size of the seal during assembly, which can provide sufficient movement space for the protruding structure and provide sufficient driving distance to push the seal into the special-shaped groove on the assembly member to achieve automatic assembly. In addition, considering that the guide member is in a stationary state when the piston member moves, in order to reduce the friction between the outer wall of the piston member and the inner wall of the guide member to reduce the obstruction to the movement of the piston member caused by the friction between the outer wall of the piston member and the inner wall of the guide member, a corresponding first gap distance can be set between the outer wall of the piston member and the inner wall of the guide member to effectively reduce the adverse conditions such as movement jamming and device wear caused by the friction between the piston member and the guide member during movement.

[0029] Optionally, the first portion of the inner wall of the positioning member is provided with the groove area;

[0030] The second portion of the inner wall of the positioning member is configured as an inclined inner wall, and the inclination angle of the inclined inner wall decreases from close to the first portion to the edge end;

[0031] The edge end of the inclined inner wall abuts against the protruding structure to assemble the positioning member on the periphery of the piston member.

[0032] In the above implementation process, the first part of the inner wall of the positioning part is provided with a groove area for combining with the moving component to place the parts to be assembled. In order to facilitate loading and unloading, the second part of the inner wall of the positioning part can also be provided as a corresponding inclined inner wall. The inclination degree of the inclined inner wall decreases from close to the first part to the edge end of the inner wall. The edge end of the inclined inner wall abuts against the raised structure, so that the positioning part is assembled on the periphery of the piston part. The inclined inner wall structure can reduce the collision, extrusion, friction, etc. generated between the inner wall and the outer wall of the piston part when the positioning part is assembled, thereby reducing adverse conditions such as movement jamming and device wear during assembly of the positioning part.

[0033] Optionally, in the assembly direction, there is a height difference between the guide member and the first end of the piston member, and the first end of the piston member is flush with the bottom end of the groove area;

[0034] The inner wall with a height difference of the first end of the piston member, the inner wall with a height difference of the inclined inner wall, and the top wall of the guide member form the placement groove.

[0035] In the above implementation process, in order to form a placement groove having three wall ends and one open end, the first end of the piston member can be flush with the bottom end of the groove area of ​​the positioning member, and a corresponding height difference can be provided between the first end of the piston member and the top of the guide member. The corresponding placement groove is formed by the inner wall of the first end of the piston member corresponding to the height difference, the inner wall of the inclined inner wall, and the top wall of the guide member. Due to the inclined nature of the inclined inner wall, the pressure on the seal in the placement groove can be effectively reduced, thereby reducing adverse deformation such as twisting caused by the seal being squeezed in the placement groove, and further improving the stability of the seal during assembly.

[0036] Optionally, the second opening of the placement groove is between the first end of the piston member and the bottom end of the groove area;

[0037] A first size of the first opening is r1, a second size of the second opening is r2, and r1>r2.

[0038] In the above implementation process, since the size of the first opening of the special-shaped groove is smaller than the size of the interior of its groove body, and the position of the second opening of the placement groove formed between the first end of the piston and the bottom end of the groove area corresponds to the position between the first opening, therefore, in order to enable the seal to be pushed into the special-shaped groove normally, the first size r1 of the first opening can be set to be larger than the second size of the second opening, so as to squeeze the seal through the second opening, so that the seal can directly enter the first opening after passing through the second opening, so as to enter the interior of the groove body of the special-shaped groove, effectively reducing the situation in which the edge of the first opening causes cutting, cutting, etc. on the seal during the assembly process when the first opening is small, thereby improving the integrity of the seal, thereby improving the stability of the seal when sealing in the special-shaped groove.

[0039] Optionally, the surface roughness of the piston member, the guide member and the positioning member is less than or equal to 0.4 μm.

[0040] In the above implementation process, taking into account the friction between the piston, guide, positioning and sealing parts during movement, the surface roughness of the piston, guide and positioning parts can be set to a smaller value, so as to reduce the wear of the seal caused by friction through the smoother device surface, as well as the adverse deformation of the seal caused by friction, such as distortion, and further optimize the sealing stability and sealing effect of the seal after assembly.

[0041] In a second aspect, an embodiment of the present application further provides an assembly method, which is applied to any of the above-mentioned assembly devices, and the method includes:

[0042] Sleeve the sealing member to be assembled on the periphery of the moving component;

[0043] Assembling a positioning member on the periphery of the motion component to form a placement groove for placing the sealing member;

[0044] Placing the part to be assembled in the placement area formed by the motion component and the positioning member; wherein the part to be assembled is provided with a special-shaped groove, the size of the first opening of the special-shaped groove is smaller than the size of the interior of the groove body, and the placement groove corresponds to the position of the special-shaped groove;

[0045] The control driving member provides pressure in the assembly direction for the part to be assembled, so as to drive the positioning member and the moving assembly to drive the part to be assembled to move, and push the sealing member into the special-shaped groove through the guide member fixed to the base; wherein, the assembly direction is perpendicular to the placement plane of the part to be assembled and points to the direction of the base.

[0046] In the above implementation process, the sealing part to be assembled can be first sleeved on the periphery of the moving component, and then the positioning part can be assembled on the periphery of the moving component. The moving component, the positioning part and the guide part form a placement groove for placing the sealing part, which effectively improves the stability of the sealing part during placement. The part to be assembled with the special-shaped groove is placed in the placement area formed by the moving component and the positioning part, and the driving part provides pressure pointing to the assembly direction of the base for the part to be assembled, so that the positioning part and the moving component drive the part to be assembled to move under the action of pressure. Moreover, due to the fixed connection between the guide part and the base, the bottom of the placement groove remains stationary, that is, during the movement of the moving component and the positioning part, the guide part can keep the sealing part stationary, so that the stationary sealing part and the moving part to be assembled generate relative movement, and the sealing part is pushed into the special-shaped groove on the part to be assembled to realize automatic assembly of the sealing part, which effectively improves the efficiency during assembly and reduces the labor costs such as time and energy required for manual assembly. Moreover, during assembly, the pressure received by the seal and the parts to be assembled is stable and uniform, which effectively reduces the adverse conditions such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off of the seal caused by uneven force, optimizes the assembly effect of the seal, and thus optimizes the sealing effect of the seal in the special-shaped groove, which can meet the assembly requirements of various types of semiconductor valves currently available.

[0047] In summary, the embodiments of the present application provide an assembly device that enables relative motion between a stationary seal and a moving part to be assembled, pushing the seal into a special-shaped groove on the part to be assembled to achieve automatic assembly of the seal, effectively improving assembly efficiency and reducing the time, effort, and other labor costs required for manual assembly. Furthermore, during assembly, the pressure applied to the seal and the part to be assembled is stable and uniform, effectively reducing adverse conditions such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off of the seal caused by uneven force, thereby optimizing the assembly effect of the seal and thus optimizing the sealing effect of the seal within the special-shaped groove, and meeting the assembly requirements of various types of semiconductor valves currently available.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0054] Since the opening of the special-shaped groove is small, for example, the cross-section of the dovetail groove is a trapezoid, and its opening is the shorter side of the trapezoid. In order to seal the special-shaped groove, a sealing ring with an outer diameter larger than the opening of the special-shaped groove is usually used for sealing. Therefore, when assembling the sealing ring, it is necessary to manually compress and squeeze the sealing ring to insert the sealing ring into the special-shaped groove. Due to factors such as unstable force direction and uneven pressure during manual assembly, the sealing ring is easily scratched, squeezed, torn, twisted, unevenly expanded and contracted, and falls off during assembly. For example, during extrusion, due to uneven force and directional instability, the opening of the special-shaped groove may cut the sealing ring, causing it to be defective or broken. Even if the sealing ring is inserted into the special-shaped groove as a whole, the sealing ring may be twisted as a whole, resulting in falling off, etc., resulting in high labor costs during assembly, and the unfavorable situation of unstable sealing effect of the sealing ring in the special-shaped groove cannot meet the current assembly requirements of semiconductor valves.

[0055] In order to solve the above problems, an embodiment of the present application provides an assembly device that can provide sufficient, stable and uniform driving force to drive the parts to be assembled to move, so that the stationary seal and the moving parts to be assembled produce relative movement, and push the seal into the special-shaped groove on the parts to be assembled to realize automatic assembly of the seal.

[0056] See also Figure 1 , Figure 1 This is a schematic cross-sectional structural diagram of an assembly device provided in an embodiment of the present application. The assembly device may include: a driving member 100, a moving component 200, a positioning member 300, a guide member 400 and a base 500.

[0057] The guide member 400 is fixed to the base 500, which can be a corresponding bottom plate or other structure with a fixing function and can be fixed to a corresponding assembly platform. The guide member 400 can be fixed to the top of the base 500 by screws, nuts, interlocking, or fixing members.

[0058] It should be noted that the guide member 400 and the positioning member 300 are sleeved on the periphery of the motion component 200, and the outer wall of the motion component 200, the inner wall of the positioning member 300, and the top wall of the guide member 400 away from the base 500 form a placement groove for placing the sealing member A. It should be noted that the placement groove can be a groove structure with three wall ends and one open end. On the placement plane of the sealing member A, the shape, groove width, groove depth (i.e., the height difference between the top wall of the guide member 400 and the outer wall of the motion component 200 and the inner wall of the positioning member 300) of the placement groove can be set according to the shape and specific dimensional parameters of the sealing member A. For example, the placement groove can be set as a circular groove.

[0059] Optionally, the first end of the motion assembly 200 and the recessed area of ​​the positioning member 300 form a placement area for the part B to be assembled. Accordingly, the shape, depth, size, and other parameters of the placement area can also be set according to the shape, thickness, and size parameters of the part B to be assembled. The second end of the motion assembly 200 is elastically connected to the base 500, and can automatically reset after assembly is completed to wait for the next assembly.

[0060] It should be noted that a special-shaped groove is provided on the part to be assembled B, and the opening of the special-shaped groove is a first opening, and the size of the first opening is smaller than the size of the interior of its groove body. For example, the special-shaped groove can be set to a variety of groove structures with an opening smaller than the inner cavity, such as a dovetail groove. Moreover, when the part to be assembled B is placed in the corresponding placement area, in the assembly direction C, the placement groove corresponds to the position of the special-shaped groove, so that accurate assembly can be achieved by aligning the positions. Therefore, the position of the placement groove and parameters such as the inner diameter (i.e., the outer wall parameters of the moving component 200) and the outer diameter (i.e., the inner wall parameters of the positioning member 300) can be set according to the actual position and size parameters of the special-shaped groove. The corresponding placement groove is formed by the provided guide member 400, the positioning member 300 and the moving component 200, so that when assembling, the placement groove accommodates the seal A to be assembled. The position of the placement groove corresponds to the position of the special-shaped groove on the part to be assembled B placed on the moving component 200, so that the special-shaped groove and the seal are statically aligned and wait for assembly.

[0061] For example, the component B to be assembled can be various types of devices that need to be sealed, such as the valve core, valve plate and other devices of a semiconductor valve. The seal A can be set to various types of components with sealing structures, such as circular and rectangular rubber sealing rings and other structures. In order to enable the seal A to fully enter the interior of the special-shaped groove of the component B to be assembled, the seal A can be set to a ring structure with a hollow structure, so that the seal A can be squeezed through the hollow structure to reduce the volume of the seal A.

[0062] It should be noted that the driving member 100 is used to provide pressure in the assembly direction C for the part B to be assembled, the positioning member 300 and the moving assembly 200 drive the part B to be assembled to move based on the pressure, and the guide member 400 pushes the seal A into the special-shaped groove based on the fixed connection with the base 500; wherein, the assembly direction C is perpendicular to the placement plane of the part B to be assembled and points to the direction of the base 500. During assembly, the driving member 100 provides pressure to the component B to be assembled pointing to the assembly direction C of the base 500, so that the positioning member 300 and the moving component 200 drive the component B to be assembled to move under the action of pressure, and since the guide member 400 is fixedly connected to the base 500, the bottom of the placement groove remains stationary, that is, during the movement of the moving component 200 and the positioning member 300, the guide member 400 can keep the seal A stationary, so that the stationary seal A and the moving component B to be assembled produce relative movement, and the seal A is pushed into the special-shaped groove on the component B to be assembled to realize automatic assembly of the seal A, which effectively improves the efficiency during assembly and reduces the time, energy and other labor costs required for manual assembly. Moreover, during assembly, the pressure received by the seal A and the part to be assembled B is stable and uniform, which effectively reduces the adverse conditions of the seal A such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off caused by uneven force, optimizes the assembly effect of the seal A, and thus optimizes the sealing effect of the seal A in the special-shaped groove, which can meet the assembly requirements of various types of semiconductor valves currently available.

[0063] For example, the guide member 400 can be various types of devices that can limit the movement direction of the moving component 200, such as a top core, etc. The moving component 200 can include various structures such as pistons with movement functions, and the positioning member 300 can be various types of devices that can be assembled, disassembled and positioned, such as a positioning loop, etc.

[0064] Optionally, the driving member 100 can be provided at one end close to the motion component 200 so as to apply corresponding pressure to the part to be assembled B through the driving member 100. For example, the driving member 100 can be a corresponding cylinder, motor or other device, and the motor can be fixed by a corresponding lifting platform or top plate or other structure, and the cylinder is fixedly connected to the motor, and the motor controls the cylinder to provide a corresponding driving force in the assembly direction C. It should be noted that a corresponding controller, such as a PLC (Programmable Logic Controller), can also be provided to control the start and stop of the motor. The initial height (no downward pressure) and working height (downward pressure) of the cylinder in the assembly direction C can be set according to the height of the part to be assembled B in the assembly direction C. The working height can be quickly adjusted according to the different heights of the parts to be assembled B, thereby realizing a fast conversion function on the assembly production line, effectively reducing the time required for manual adjustment of the working height, and further improving the efficiency of assembly.

[0065] See also Figure 2 , Figure 2 This is a schematic diagram of another assembly device according to an embodiment of the present application, wherein a motion assembly 200 may include a piston 210, a connector 220, and an elastic member 230. Considering that the motion assembly 200 needs to be restored to its original position after assembly to await the next assembly process, the motion assembly 200 may be elastically connected to the base 500 to achieve automatic reset. The motion assembly 200 may include a piston 210 for placing the part B to be assembled, as well as a connector 220 and an elastic member 230 that are elastically connected to the base 500.

[0066] The guide member 400 and the positioning member 300 are sleeved on the outer wall of the piston member 210. The first end of the piston member 210 is used to place the component B to be assembled. The second end of the piston member 210 is connected to the first end of the connecting member 220, and the second end of the connecting member 220 is fixed to the base 500. The elastic member 230 is sleeved on the outside of the connecting member 220. The first end of the elastic member 230 is connected to the second end of the piston member 210, and the second end of the elastic member 230 is fixed to the base 500. The piston member 210, the guide member 400, and the positioning member 300 respectively serve as three wall ends, forming a placement groove with one end open. The second end of the piston member 210 is elastically connected to the base 500 through the connecting member 220 and the elastic member 230 sleeved on the outside of the connecting member 220. By connecting the piston member 210, the connecting member 220 and the elastic member 230 with the external guide member 400, the positioning member 300, the base 500 and other structures, elastic movement in the corresponding assembly direction C and elastic reset movement after assembly are achieved, thereby realizing the automatic assembly function and effectively improving the efficiency and stability during assembly.

[0067] For example, the connecting member 220 may include corresponding connecting rods, moving shafts and other devices, the elastic member 230 may include various types of springs, disc springs, bellows and other structures, and a corresponding internal cavity may be provided between the base 500 and the guide member 400 to place the connecting member 220 and the elastic member 230.

[0068] Optionally, the piston member 210 may include a fixing member, a first piston structure, and a second piston structure. The first piston structure and the second piston structure are fastened together by a fixing member, the first piston structure is used to place the part B to be assembled, and the second piston structure is connected to the connecting member 220 and the elastic member 230. Taking into account the movement characteristics of the piston member 210, in order to reduce the difficulty in producing the piston member 210, the piston member 210 can be split into two piston structures, and the two piston structures are fastened together by corresponding fixing members to move synchronously. The first piston structure is used to place the part B to be assembled, and the second piston structure is used to connect with the connecting member 220 and the elastic member 230 to achieve fixation of the part B to be assembled and elastic connection with the base 500. The difficulty of producing and manufacturing the integrated piston member 210 can be reduced by means of an assembly structure, and the structural accuracy and stability of the piston member 210 during movement are effectively improved.

[0069] For example, the fixing member may include various types of screws, such as countersunk screws and other devices with a fixing function.

[0070] It should be noted that the first piston structure can be set to a structure with a platform surface and a groove to achieve the function of placing the component B to be assembled and connecting the second piston structure. The second piston structure can also be set to a structure with a groove and a protruding end to fix the connecting part 220 through the groove and connect the elastic part 230 sleeved on the outside of the connecting part 220 through the protruding end.

[0071] Optionally, in order to allow the guide member 400 to be sleeved on the exterior of the piston member 210 so as to restrict the movement of the piston member 210 in the assembly direction C through the guide member 400, the guide member 400 may be provided with n movement grooves D, where n is a positive integer greater than or equal to 2. For example, in order to improve the uniformity with which the guide member 400 restricts the movement direction of the piston member 210, the n movement grooves D are provided at the same height in the assembly direction C, and the n movement grooves D are evenly distributed on the side of the guide member 400.

[0072] It should be noted that the outer wall of the piston member 210 can be provided with n protrusions 211, the number of which is the same as the number of the motion grooves D. The protrusions 211 are configured to pass through the motion grooves D, and the piston member 210 moves within the motion grooves D based on the protrusions 211. The protrusions 211 pass through the motion grooves D provided on the guide member 400, so that the guide member 400 is sleeved on the outer wall of the piston member 210. During the movement of the motion assembly 200, the guide member 400 can provide corresponding movement space in the assembly direction C for the protrusions 211 based on the motion grooves D provided thereon, thereby limiting the movement direction of the piston member 210. Moreover, within the movement space provided by the motion grooves D, the guide member 400 can also remain stationary during the movement of the motion assembly 200, effectively reducing the impact of the motion of the motion assembly 200 on the guide member 400, further improving the stability of the guide member 400, and thus improving the stability of the seal A placed on the guide member 400.

[0073] For example, the shape of the protruding structure 211 can be designed according to the specific connection structure between the piston member 210 and the guide member 400 and the positioning member 300. For example, it can be set to a stepped shape with multiple levels to facilitate the assembly between the piston member 210 and the guide member 400 and the positioning member 300.

[0074] It should be noted that during the movement of the moving component 200, the protruding structure 211 will reciprocate along the assembly direction C. Therefore, in the assembly direction C, in order to enable the protruding structure 211 to achieve smooth movement in the moving groove D on the guide member 400, the first length of the moving groove D is greater than the second length of the protruding structure 211, and the length difference between the first length and the second length is set based on the outer diameter parameter of the seal A, that is, the advancement distance can be determined according to the actual size of the seal A during assembly, which can provide sufficient movement space for the protruding structure 211 and provide sufficient driving distance to push the seal A into the special-shaped groove on the part B to be assembled to achieve automatic assembly.

[0075] For example, the length difference between the first length and the second length can be set to be slightly larger than the outer diameter parameter of seal A. For example, when the outer diameter parameter of seal A is 0.5mm, the length difference can be set to 0.55-0.65mm to provide sufficient advancement distance to ensure that seal A can enter the interior of the special-shaped groove.

[0076] It should be noted that, considering that the guide member 400 is in a stationary state when the piston member 210 moves, in order to reduce the obstruction to the movement of the piston member 210 caused by the friction between the outer wall of the piston member 210 and the inner wall of the guide member 400, on the placement plane perpendicular to the assembly direction C, there is a first gap distance between the outer wall of the piston member 210 and the inner wall of the guide member 400. A corresponding first gap distance can be set between the outer wall of the piston member 210 and the inner wall of the guide member 400 to effectively reduce adverse conditions such as movement jamming and device wear caused by the friction between the piston member 210 and the guide member 400 during movement.

[0077] For example, the first gap distance can be set to 0.018mm-0.022mm, which can effectively reduce the friction caused by a too small distance, and can also effectively reduce the adverse conditions such as cutting caused by the seal A entering the gap due to a too large distance.

[0078] Please continue reading Figure 2 The first portion of the inner wall of the positioning member 300 is provided with a grooved area, and the second portion of the inner wall of the positioning member 300 is provided with an inclined inner wall. The inclination angle of the inclined inner wall decreases from the first portion to the edge end. The edge end is the end of the positioning member 300 that contacts the piston member 210 during assembly. The edge end of the inclined inner wall abuts the protrusion 211 to assemble the positioning member 300 around the periphery of the piston member 210. The inclined inner wall structure enables automatic positioning and assembly of the positioning member 300 and the piston member 210, so that the special-shaped groove of the assembly part B corresponds to the placement groove position, thereby reducing adverse effects such as cutting, twisting, and torsion of the sealing member A caused by misalignment of the two grooves. It also reduces collision, extrusion, and friction between the inner wall of the positioning member 300 and the outer wall of the piston member 210 during assembly, thereby reducing adverse effects such as movement jamming and component wear during assembly of the positioning member 300.

[0079] It should be noted that the inclination angle of the inclined inner wall can be set according to various parameters such as the length of the positioning member 300 in the assembly direction C, the position and length of the protruding structure 211 and the thickness of the guide member 400.

[0080] Please continue reading Figure 2To form a placement groove having three wall ends and one open end, in assembly direction C, the guide member 400 and the first end of the piston member 210 have a height difference. The first end of the piston member 210 is flush with the bottom end of the recessed area. The inner wall of the height difference of the first end of the piston member 210, the inner wall of the height difference of the inclined inner wall, and the top wall of the guide member 400 form the placement groove. The first end of the piston member 210 can be flush with the bottom end of the recessed area of ​​the positioning member 300, and a corresponding height difference can be provided between the first end of the piston member 210 and the top of the guide member 400. The corresponding placement groove is formed by the inner wall of the first end of the piston member 210 corresponding to the height difference, the inner wall of the inclined inner wall, and the top wall of the guide member 400. The inclined nature of the inclined inner wall effectively reduces the pressure on the seal A in the placement groove, thereby reducing adverse deformation such as twisting of the seal A caused by being squeezed in the placement groove, further improving the stability of the seal A during assembly.

[0081] It should be noted that the second opening of the placement groove is located between the first end of the piston member 210 and the bottom end of the groove area, and the first dimension of the first opening is r1, and the second dimension of the second opening is r2. Since the size of the first opening of the special-shaped groove is smaller than the size of the interior of its groove body, and the position of the second opening of the placement groove formed between the first end of the piston member 210 and the bottom end of the groove area corresponds to the position of the first opening, in order to enable the seal A to be normally pushed into the special-shaped groove, the first dimension of the first opening can be set to be larger than the second dimension of the second opening, that is, r1>r2, so as to squeeze the seal A through the second opening, so that the seal A can directly enter the first opening after passing through the second opening, and enter the interior of the groove body of the special-shaped groove, effectively reducing the situation in which the edge of the first opening cuts or cuts the seal A during assembly when the first opening is small, thereby improving the integrity of the seal A and thus improving the stability of the seal A when sealing in the special-shaped groove.

[0082] For example, in order to reduce the adverse effects on seal A caused by the second opening of the placement groove being too small, such as seal A getting stuck in the second opening, seal A being cut by the edge of the second opening, etc., r1-r2 can be made ≤ 0.15mm so that seal A can pass through the second opening smoothly.

[0083] It should be noted that, considering the friction between the piston 210, the guide 400, the positioning member 300, and the seal A during movement, the surface roughness of the piston 210, the guide 400, and the positioning member 300 can be set to a relatively low value. For example, by selecting appropriate device materials, machining accuracy, and process control, the surface roughness of the piston 210, the guide 400, and the positioning member 300 can be less than or equal to 0.4 μm, that is, less than or equal to Ra (Arithmetical Mean Roughness, the microscopic roughness of the surface of a machined part) 0.4, so that the arithmetic mean roughness value of the surfaces of the piston 210, the guide 400, and the positioning member 300 is less than or equal to 0.4 μm. The smoother device surface can reduce the wear of the seal A caused by friction, as well as the adverse deformation of the seal A caused by friction, such as distortion, thereby further optimizing the sealing stability and sealing effect of the assembled seal A.

[0084] Optionally, the corresponding processing accuracy and process control may include: using a high-precision grinder, or selecting a suitable grinding wheel type and particle size, and appropriate grinding parameters (such as grinding speed, feed rate, etc.) for grinding to reduce surface roughness, and using polishing paste, polishing cloth and other polishing tools, combined with appropriate polishing pressure and speed to polish the device surface, or using electrolytic polishing to remove the surface micro-roughness of the device through electrochemical action, and can also achieve a higher surface finish through ultrasonic processing, laser processing and other methods.

[0085] See also Figure 3 , Figure 3 A flowchart of an assembly method provided in an embodiment of the present application is provided. The method may include steps S610-S640.

[0086] Step S610: The sealing member to be assembled is placed on the periphery of the moving component.

[0087] Step S620: assemble the positioning member on the periphery of the moving component to form a placement groove for placing the sealing member.

[0088] Among them, in order to facilitate the assembly of the seal, the seal to be assembled can be first placed on the periphery of the moving component, and then the positioning component can be assembled on the periphery of the moving component. The moving component, the positioning component and the guide component form a placement groove for the seal. By assembling the seal first and then the positioning component, the stability of the seal during placement is effectively improved.

[0089] Step S630: placing the part to be assembled in the placement area formed by the moving component and the positioning part.

[0090] Among them, a special-shaped groove is provided on the part to be assembled, the size of the first opening of the special-shaped groove is smaller than the size of the interior of the groove body, and the placement groove corresponds to the position of the special-shaped groove to achieve high-precision assembly.

[0091] Step S640: Control the driving member to provide pressure in the assembly direction for the part to be assembled, so as to drive the positioning member and the moving assembly to move the part to be assembled, and push the sealing member into the special-shaped groove through the guide member fixed to the base.

[0092] The assembly direction is perpendicular to the placement plane of the part to be assembled and points toward the base. The part to be assembled, which has a special-shaped groove, is placed in the placement area formed by the moving assembly and the positioning member. The driving member applies pressure to the part to be assembled in the assembly direction of the base, so that the positioning member and the moving assembly drive the part to be assembled under the action of pressure. Moreover, due to the fixed connection between the guide member and the base, the bottom of the placement groove remains stationary. That is, during the movement of the moving assembly and the positioning member, the guide member can keep the seal stationary, thereby generating relative movement between the stationary seal and the moving part to be assembled, and pushing the seal into the special-shaped groove on the part to be assembled to achieve automatic assembly of the seal.

[0093] For example, the first piston structure and the second piston structure are locked into a whole by countersunk screws, an elastic part is installed in the base, and a connecting part is provided in the elastic part to fasten the integrated piston part to the base, the guide part is inserted into the step inside the base and fixed, the seal is inserted into the piston part, and then the positioning part is assembled on the moving component, and the parts to be assembled are placed in the placement area composed of the positioning part and the moving component. The controller can control the motor to drive the lifting platform to the required height, and then the cylinder moves downward to push the product, and the positioning part abuts the moving component, driving the moving component to move downward as a whole. At this time, the guide part is equivalent to moving upward, pushing the seal through the placement groove which is smaller than the opening of the special-shaped groove into the inside of the special-shaped groove, completing the entire assembly process.
