Description

Technical Field

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

[0002] When assembling the 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 with lubricants when assembling with sealing rings, and can only be assembled manually. The opening of the special-shaped groove is small, and the sealing ring needs to be compressed and squeezed when assembling it. Due to factors such as unstable force direction and uneven pressure during manual assembly, the sealing ring is easily scratched, squeezed, torn, twisted, unevenly stretched, and fallen off during assembly, resulting 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. Summary of the invention

[0003] In view of this, an object of the embodiments of the present application is to provide an assembly device and an assembly method 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 moving assembly, a positioning member, a guide member and a base;

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

[0006] Wherein, the guide member and the positioning member are sleeved on the periphery of the moving component, and the outer wall of the moving 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 placing 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 inside 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, the corresponding placement grooves are formed by the provided guides, positioning members and moving components, so that during assembly, the placement grooves accommodate and place the seals to be assembled, and the position of the placement grooves corresponds to the position of the special-shaped grooves on the parts to be assembled placed on the moving components, so that the special-shaped grooves and the seals are statically aligned to wait for assembly. During assembly, the driving member provides pressure pointing to the assembly direction of the base for the parts to be assembled, so that the positioning members and the moving components drive the parts to be assembled to move under the action of pressure, and because the guide members are fixedly connected to the base, the bottom of the placement grooves remains stationary, that is, during the movement of the moving components and the positioning members, the guide members can keep the seals stationary, so that the stationary seals and the moving parts to be assembled produce relative movement, and the seals are pushed into the special-shaped grooves on the parts to be assembled to realize automatic assembly of the seals, 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 and the parts to be assembled is stable and uniform, which effectively reduces the adverse conditions of the seal such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off 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 the assembly is completed to 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 member for placing the parts to be assembled, and a connecting member and an elastic member elastically connected to the base. The piston member, the guide member and the positioning member are respectively used as three wall ends to form a placement groove with an open end. The second end of the piston member is elastically connected to the base through a connecting member and an elastic member sleeved on the outside of the connecting member. The elastic movement in the corresponding assembly direction and the elastic resetting movement after the assembly are achieved by connecting the piston member, the connecting member and the elastic member with the external guide member, the positioning member, the base and other structures, 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 and connected via the fixing member;

[0017] The first piston structure is used to place the parts 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 motion characteristics of the piston part, in order to reduce the difficulty in manufacturing the piston part, the piston part can be split into two piston structures, and the two piston structures are fastened and connected by corresponding fixing parts for synchronous movement. The first piston structure is used to place the parts to be assembled, and the second piston structure is used to connect with the connecting parts and the elastic parts to achieve the fixation of the parts to be assembled and the elastic connection with the base. The difficulty of manufacturing the integrated piston part can be reduced by assembling the structure, which effectively improves the structural accuracy and stability of the piston part during movement.

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

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

[0022] The protrusion 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 make the guide member 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, and, 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 influence of the moving assembly on the guide member during movement, 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 member and an inner wall of the guide member.

[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 moving groove on the guide, the first length of the moving 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 part to be assembled to achieve automatic assembly. In addition, considering that the guide is in a stationary state when the piston moves, in order to reduce the friction between the outer wall of the piston and the inner wall of the guide to reduce the obstruction to the movement of the piston, a corresponding first gap distance can be set between the outer wall of the piston and the inner wall of the guide, so as to effectively reduce the unfavorable conditions such as movement jamming and device wear caused by the friction between the piston and the guide during the movement.

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

[0030] The second part 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 part 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 member 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 member 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 member is assembled on the periphery of the piston member. The inclined inner wall structure can reduce the collision, extrusion, friction and the like between the inner wall and the outer wall of the piston member when the positioning member is assembled, thereby reducing the adverse conditions such as movement jamming and device wear when the positioning member is assembled.

[0033] Optionally, in the assembly direction, the guide member and the first end of the piston member have a height difference, 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 with 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 made between the first end of the piston member and the top of the guide member, so that 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 characteristics of the inclined inner wall, the pressure on the seal in the placement groove can be effectively reduced, thereby reducing the adverse deformation such as distortion 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 member and the bottom end of the groove area corresponds to 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 that the seal can be squeezed 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 cutting, cutting, etc. of the seal caused by the edge of the first opening during the assembly process when the first opening is small, so as to improve 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 twisting, thereby further optimizing 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 moving 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 inside 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 seal to be assembled can be first sleeved 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 placing the seal, which effectively improves the stability of the seal when placed. The part to be assembled with a special-shaped groove is placed in the placement area formed by the moving component and the positioning component, and the driving component provides pressure pointing to the assembly direction of the base for the part to be assembled, so that the positioning component and the moving component drive the part to be assembled to move under the action of pressure, and because the guide component 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 component, the guide component can keep the seal stationary, so that the stationary seal and the moving part to be assembled produce 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, 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 and the parts to be assembled is stable and uniform, which effectively reduces the adverse conditions of the seal such as scratches, cracks, tears, twisting, uneven expansion and contraction, and falling off 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 and an assembly method, which can make a stationary seal and a moving part to be assembled produce relative movement, and push the seal into the special-shaped groove on the part to be assembled to realize automatic assembly of the seal, which effectively improves the efficiency during assembly and reduces the time, energy and other labor costs required for manual assembly. In addition, the pressure received by the seal and the part to be assembled during assembly 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 at present.

[0053] The technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of 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 and 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 stretched, and fallen off during assembly. For example, during extrusion, due to uneven force and unstable direction, the opening of the special-shaped groove may cut the sealing ring, causing the sealing ring 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 that the sealing effect of the sealing ring in the special-shaped groove is unstable, 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 part to be assembled to move, so that the stationary seal and the moving part to be assembled can produce relative movement, and the seal can be pushed into the special-shaped groove on the part to be assembled to realize automatic assembly of the seal.

[0056] See also Figure 1 , Figure 1 This is a schematic diagram of the cross-sectional structure 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 on the base 500, and the base 500 can be a corresponding structure such as a bottom plate with a fixing function, which can be fixed on a corresponding assembly platform. The guide member 400 can be fixed on the top of the base 500 by means of screws and nuts, interlocking, etc. 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 seal 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 seal 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) and other parameters of the placement groove can be set according to the shape and specific size parameters of the seal A, for example, the placement groove can be set as a circular groove, etc.

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

[0060] It should be noted that a special-shaped groove is provided on the part B to be assembled, 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 inner part of the groove body. For example, the special-shaped groove can be set to a dovetail groove or other groove structures with a smaller opening than the inner cavity. In addition, when the part B to be assembled 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 through the aligned position. Therefore, the position of the placement groove and the parameters such as the inner diameter (i.e., the outer wall parameter of the motion component 200) and the outer diameter (i.e., the inner wall parameter 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 set guide member 400, the positioning member 300 and the motion component 200, so that when assembling, the sealing member A to be assembled can be accommodated and placed by the placement groove, and the position of the placement groove corresponds to the position of the special-shaped groove on the part B to be assembled placed on the motion component 200, so that the special-shaped groove and the sealing member are aligned statically to 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 completely 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 pointing to the assembly direction C of the base 500 for the component B to be assembled, 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 labor costs such as time and energy required for manual assembly. Moreover, during assembly, the pressure received by the seal A and the assembly part 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 arranged at one end close to the motion component 200, so as to apply corresponding pressure to the assembly part 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 set to control the start and stop of the motor, and 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 assembly part B in the assembly direction C, and the working height can be quickly adjusted according to the different heights of the assembly parts 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 assembly efficiency.

[0065] See also Figure 2 , Figure 2 A schematic diagram of another assembly device provided in an embodiment of the present application, wherein the motion assembly 200 may include a piston member 210, a connecting member 220, and an elastic member 230. Considering that the motion assembly 200 needs to be restored to its original position after assembly to wait for the next assembly process, in order to achieve automatic resetting, the motion assembly 200 may be elastically connected to the base 500. The motion assembly 200 may include a piston member 210 for placing the assembly B to be assembled, and a connecting member 220 and an elastic member 230 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 assembly part B. The second end of the piston member 210 is connected to the first end of the connecting member 220. The second end of the connecting member 220 is fixed on 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. The second end of the elastic member 230 is fixed on the base 500. The piston member 210, the guide member 400 and the positioning member 300 are respectively used as three wall ends to form 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 and connected 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 motion characteristics of the piston member 210, in order to reduce the difficulty in manufacturing the piston member 210, the piston member 210 can be split into two piston structures, and the two piston structures are fastened and connected by corresponding fixing members for synchronous movement. 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 the fixation of the part B to be assembled and the elastic connection with the base 500. The difficulty of 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 sleeve the guide member 400 on the outside of the piston member 210 so as to limit 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 of the guide member 400 in limiting the movement direction of the piston member 210, the n movement grooves D are set at the same height in the assembly direction C, and the n movement grooves D are evenly arranged on the side of the guide member 400.

[0072] It should be noted that the outer wall of the piston member 210 may be provided with n protrusion structures 211, the number of the protrusion structures 211 is the same as the number of the motion grooves D, the protrusion structures 211 are configured to pass through the motion grooves D, and the piston member 210 moves in the motion grooves D based on the protrusion structures 211. The protrusion structures 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 component 200, the guide member 400 can provide the protrusion structure 211 with a corresponding motion space in the assembly direction C based on the motion grooves D provided thereon, so as to limit the motion direction of the piston member 210, and, in the motion space provided by the motion grooves D, the guide member 400 can also be in a stationary state during the movement of the motion component 200, effectively reducing the impact of the motion component 200 on the guide member 400 when it moves, 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 protrusion 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 assembly part B 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 0.5 mm, the length difference can be set to 0.55-0.65 mm 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 resistance 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, and 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 the friction between the piston member 210 and the guide member 400 during movement, thereby effectively reducing the movement jamming, device wear and other adverse conditions 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 0.018 mm-0.022 mm, 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 , wherein the first part of the inner wall of the positioning member 300 is provided with a groove area, and the second part of the inner wall of the positioning member 300 is provided as an inclined inner wall, the inclination angle of the inclined inner wall decreases from the first part to the edge end, the edge end is the end that contacts the positioning member 300 when assembling with the piston member 210, and the edge end of the inclined inner wall abuts against the protruding structure 211, so that the positioning member 300 is assembled on the periphery of the piston member 210. The automatic positioning and assembly of the positioning member 300 and the piston member 210 can be achieved through the inclined inner wall structure, so that the special-shaped groove of the assembly part B can correspond to the position of the placement groove, thereby reducing the unfavorable conditions such as cutting, twisting, and torsion of the sealing member A caused by the misalignment of the two grooves, and reducing the collision, extrusion, friction, etc. between the inner wall of the positioning member 300 and the outer wall of the piston member 210 when assembling, thereby reducing the unfavorable conditions such as motion jamming and device wear when assembling 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 2In order to form a placement groove with three wall ends and one open end, in the assembly direction C, the guide member 400 has a height difference with the first end of the piston member 210, the first end of the piston member 210 is flush with the bottom end of the groove area, and 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 a placement groove. The first end of the piston member 210 can be flush with the bottom end of the groove area of ​​the positioning member 300, and the first end of the piston member 210 and the top of the guide member 400 have a corresponding height difference, so that 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. Due to the inclined characteristics of the inclined inner wall, the pressure on the seal A in the placement groove can be effectively reduced, thereby reducing the unfavorable deformation such as distortion caused by the seal A being squeezed in the placement groove, and further improving the stability of the seal A during assembly.

[0081] It should be noted that, the second opening of the placement groove is between the first end of the piston member 210 and the bottom end of the groove area, the first size of the first opening is r1, and the second size 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 inside of its groove body, and 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 between the first opening, therefore, in order to enable the seal A to be normally pushed into the special-shaped groove, the first size of the first opening can be set to be larger than the second size 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, so as to enter the inside of the groove body of the special-shaped groove, effectively reducing the cutting and cutting of the seal A by the edge of the first opening during the assembly process when the first opening is small, so as to improve the integrity of the seal A, thereby 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 the movement, the surface roughness of the piston 210, the guide 400 and the positioning member 300 can be set to a smaller value, for example, by selecting the corresponding device material, processing accuracy and process control, so that the surface roughness of the piston 210, the guide 400 and the positioning member 300 is less than or equal to 0.4μm, that is, less than or equal to Ra (Arithmetical Mean Roughness, the microscopic roughness of the surface of the machined part) 0.4, so that the arithmetic mean roughness value of the surface of the piston 210, the guide 400 and the positioning member 300 is less than or equal to 0.4μm. The wear of the seal A caused by friction and the unfavorable deformation of the seal A caused by friction can be reduced through the device surface with higher smoothness, and the sealing stability and sealing effect of the seal A after assembly are further optimized.

[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 tools such as polishing paste and polishing cloth, combined with appropriate polishing pressure and speed to polish the device surface, or using electrolytic polishing to remove microscopic surface roughness of the device through electrochemical action, and achieving a higher surface finish through ultrasonic processing, laser processing, etc.

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

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

[0087] Step S620, assembling 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 firstly sleeved 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 placing 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 arranged on the part to be assembled, the size of the first opening of the special-shaped groove is smaller than the size inside the groove body, and the placement groove corresponds to the position of the special-shaped groove to achieve high-precision assembly.

[0091] Step S640, controlling 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 drive the part to be assembled to move, and pushing 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 to the base. The part to be assembled with the special-shaped groove is placed in the placement area formed by the moving component and the positioning member, and the driving member provides pressure to the part to be assembled in the assembly direction pointing to 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 produce 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.

[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, the positioning part abuts the moving component, and drives 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.
