Description

Technical Field

[0001] This invention relates to the field of air spring technology, and more specifically, to a method and system for assembling a bladder assembly. Background Technology

[0002] An air spring mainly consists of a soft bulb sleeve, end caps, an inflation port, and a protective cover, each with a clearly defined function. The end caps seal the soft bulb sleeve and connect it to the external structure; the inflation port allows compressed air to be injected into or expelled from the soft bulb sleeve to regulate its position; the protective cover protects the soft bulb sleeve from external dust, sand, oil, and other contaminants; the soft bulb sleeve also contains a clamping ring, which engages with the inner circumferential wall of the protective cover to fix the position of the soft bulb sleeve. During the manufacturing process, the clamping ring needs to be press-fitted into a predetermined position inside the soft bulb sleeve. Because the outer diameter of the clamping ring is larger than the soft bulb sleeve in its free state, the soft bulb sleeve needs to expand and deform during the pressing process to accommodate the clamping ring.

[0003] Because the soft capsule sleeve is stored in a stacked state in its free state, its cross-section is elliptical. When the pressure head presses against the clamping ring, the soft capsule sleeve will expand. However, due to the influence of the initial shape of the soft capsule sleeve, its expansion process is uneven, which makes the pressing process of the pressure head unsmooth. Summary of the Invention

[0004] To address the issue of smoothness in pressing the pressure head into the soft bladder sleeve and attaching the clamping ring, this invention provides a method and system for assembling a bladder sleeve assembly.

[0005] In a first aspect, the present invention provides a method for assembling a capsule-skin assembly, the method comprising:

[0006] Based on the soft capsule sleeve being clamped and sealed at one end, and the buckling ring abutting against the pressing unit, the driving guide unit and the pressing unit move toward the soft capsule sleeve at a first speed.

[0007] Based on L1≥A×L0, the air supply assembly provides airflow into the soft sleeve with the first airflow parameter; wherein, L1 is the arc length of the first guide cone of the guide unit abutting the end of the soft sleeve away from the clamping end, L0 is the inner diameter circumference of the soft sleeve in the free state away from the clamping end, 0.3≤A≤0.75; the maximum outer diameter of the first guide cone is smaller than the inner diameter of the clamping ring;

[0026] Based on the air supply component, airflow is provided into the soft capsule with a third airflow parameter to retract the second guide cone.

[0033] In a second aspect, the present invention provides a capsule / skin assembly system, wherein the capsule / skin assembly system is applied to the capsule / skin assembly method of any of the above embodiments, and the capsule / skin assembly system comprises:

[0034] A pressing assembly includes a pressing base unit, a guiding unit, and a pressing unit; the pressing base unit includes a pressing base plate and a first driving part; the guiding unit includes a first guiding cone; one end of the first guiding cone passes through the pressing unit and is detachably connected to the pressing base plate, and the other end extends away from the pressing base plate; the pressing unit is detachably connected to the pressing base plate; the first driving part drives the pressing base plate to move axially along the pressing unit; the inner peripheral wall of the pressing unit is slidably connected to the first guiding cone; the outer diameter of the end of the first guiding cone away from the pressing unit gradually decreases in the direction away from the pressing unit.

[0035] A support assembly is spaced out at one end of the first guide cone away from the pressing unit;

[0036] A frame assembly, wherein the frame assembly is detachably connected to the support assembly; and the frame assembly is detachably connected to the pressure base unit.

[0037] The capsule skin assembly includes a soft capsule sleeve and a clamping ring;

[0038] An air supply assembly that supplies air to the soft capsule sheath;

[0039] The capsule assembly system further includes a first state and a second state; the first state includes the support component fixing the soft capsule, and the clamping ring abutting against the end of the pressing unit near the first guide cone; the second state includes the support component and the pressing unit respectively sealing both ends of the soft capsule, the soft capsule expanding radially therein, and the clamping ring being detachably connected to the inner peripheral wall of the soft capsule.

[0040] To address the issue of smoothness in pressing the clamping ring into the soft sleeve by the pressure head, this invention offers the following advantages:

[0041] Before the soft capsule sleeve is pressed into the clamping ring, it is often flattened due to stacking and transportation, resulting in a cross-sectional shape that is close to an ellipse. By driving the guide unit and the pressing unit to move towards the soft capsule sleeve at a first speed, and when the arc length of the first guide cone abutting the end of the soft capsule sleeve away from the clamping end meets the set condition, the air supply component supplies air with a first airflow parameter. This allows the cross-sectional shape of the soft capsule sleeve to quickly approach a circle, avoiding the first guide cone contacting and rubbing against the arc surface in the minor axis direction of the elliptical cross-section, which would cause the soft capsule sleeve to curl and affect the pressing into the clamping ring. By driving the pressing unit and the guide unit to disengage from the soft capsule sleeve after the soft capsule sleeve expands radially and the pressing unit delivers the clamping ring to the set position, and then reducing the airflow supply to the air supply component until it stops, the soft capsule sleeve can slowly contract to fix the position of the clamping ring. At the same time, when the pressing unit and the guide unit disengage from the soft capsule sleeve, there is still an air film between them and the inner wall of the soft capsule sleeve to reduce friction, facilitating the smooth disengagement of the pressing unit and the guide unit and protecting the soft capsule sleeve.

[0055] During the assembly of the capsule assembly 40, the clamping ring 42 needs to be pressed into a predetermined position inside the soft capsule sleeve 41. Since the soft capsule sleeve 41 is stored in a stacked state in its free state, its cross-section is elliptical. When the clamping ring 42 is pressed in, the soft capsule sleeve 41 needs to expand and deform to accommodate the clamping ring 42. During the pressing process of the clamping ring 42, the soft capsule sleeve 41 will expand unevenly. This phenomenon directly leads to the pressing process of the clamping ring 42 being unsmooth.

[0056] Example 1:

[0057] To address the aforementioned issues, this embodiment discloses a method for assembling a skin assembly 40.

[0058] In this embodiment, as Figure 1 As shown, the assembly method of the capsule skin assembly 40 includes steps S10 to S30:

[0059] Step S10: Based on the clamped seal at one end of the soft capsule sleeve 41 and the abutment of the clamping ring 42 against the pressing unit 13, the guide unit 12 and the pressing unit 13 are driven to move towards the soft capsule sleeve 41 at a first speed. This step prepares for the subsequent inflation of the soft capsule sleeve 41 and the pressing of the clamping ring 42, allowing the guide unit 12 and the pressing unit 13 to initially approach the soft capsule sleeve 41, laying the foundation for subsequent operations. Figure 2 As shown, the soft capsule assembly 40 assembly system includes a pressing assembly 10, a support assembly 20, and an air supply assembly 50. The pressing assembly 10 includes a guide unit 12 and a pressing unit 13. One end of the guide unit 12 is a guide end, shaped like a frustocone, and the other end is slidably connected to the inner peripheral wall of the pressing unit 13. The end of the pressing unit 13 near the guide unit 12 can be used to position the clamping ring 42 using magnetic adsorption or clamping. The support assembly 20 is coaxially spaced from the guide unit 12. The support assembly 20 is used to position and clamp one end of the soft capsule 41. The air supply assembly 50 can supply airflow into the soft capsule 41.

[0060] Step S20: Based on L1≥A×L0, the air supply component 50 supplies airflow into the soft sleeve 41 with the first airflow parameter. Where 0.3≤A≤0.75, the optimal value of A is 0.4~0.5. That is, when the contact arc length L1 between the first guide cone 121 of the guide unit 12 and the end of the soft sleeve 41 away from the clamping end is greater than or equal to the product of the inner diameter circumference L0 of the soft sleeve 41 in its free state away from the clamping end and the constant A, the air supply component 50 is controlled to supply air into the soft sleeve 41. When the soft capsule sleeve 41 is stored in a free state, it forms an elliptical cross-section due to pressure. When the first guide cone 121 abuts against the soft capsule sleeve 41, it first abuts against the arc surface in the direction of the minor axis of the elliptical cross-section, while the arc surface in the direction of the major axis of the elliptical cross-section still maintains a certain gap with the first guide cone 121. To prevent the arc surface in the direction of the minor axis of the elliptical cross-section of the soft capsule sleeve 41 from curling under the friction between it and the first guide cone 121 (that is, the end face of the soft capsule sleeve 41 bends towards its central axis, causing the soft capsule sleeve 41 to curl inward), inflation is performed by limiting the arc length of the contact between the first guide cone 121 and the soft capsule sleeve 41 away from the clamping end. Through the guidance of the first guide cone 121 and the impact of the airflow, the cross-sectional shape of the soft capsule sleeve 41 approaches a circle, reducing the curling of the soft capsule sleeve 41. At the same time, it can also improve the expansion uniformity of the soft capsule sleeve 41, and at the same time, the inflation method avoids damage to the soft capsule sleeve 41 caused by mechanical tensile deformation. The maximum outer diameter of the first guide cone 121 is smaller than the inner diameter of the clamping ring 42. The dimensional relationship between the first guide cone 121 and the clamping ring 42 can avoid interference during press-fitting.

[0061] In step S30, based on the radial expansion of the soft sleeve 41, the pressing unit 13 is driven to move the clamping ring 42 to a set position. The pressing unit 13 and the guiding unit 12 are then driven to move away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until it stops. Since the support assembly 20 and the pressing assembly 10 respectively block both ends of the soft sleeve 41, a sealed space is formed inside the soft sleeve 41. After the air supply assembly 50 supplies airflow into the sealed space, the soft sleeve 41 can expand and deform radially. By gradually reducing the airflow supply during the retraction of the pressing unit 13 and the guiding unit 12 after the clamping ring 42 is in place, the soft sleeve 41 gradually retracts to surround and hold the clamping ring 42, so that the clamping ring 42 has a fixed position relative to the soft sleeve 41, avoiding the friction between the soft sleeve 41 and the pressing unit 13 and the guiding unit 12 from affecting the position of the clamping ring 42. At the same time, the slow reduction in airflow supply can prevent the soft sleeve 41 from contracting rapidly, reduce the interaction force between the soft sleeve 41 and the pressing unit 13 and the guiding unit 12, thereby reducing the friction between the pressing unit 13 and the guiding unit 12 and the inner peripheral wall of the soft sleeve 41, and improving the smoothness of evacuation.

[0062] Furthermore, based on L1≥A×L0, it includes: based on 0.9×L0≥L1≥A×L0. Since the soft capsule sleeves 41 in the free state are stored in multiple layers, the cross-sectional shape of the soft capsule sleeves 41 in the upper layer has a smaller roundness (i.e., close to a circle), while the cross-sectional shape of the soft capsule sleeves 41 in the lower layer has a larger roundness (i.e., close to an ellipse, and relatively flat). By limiting the upper limit of the contact arc length between the first guide cone 121 and the soft capsule sleeves 41 in the free state, the soft capsule sleeves 41 with a larger round cross-sectional shape can contact more of the arc surface with the first guide cone 121 before air is supplied, thereby reducing airflow consumption and lowering production costs.

[0063] In other embodiments, the assembly method of the bladder sleeve 40 further includes step S40, which involves supplying air to the air supply assembly 50 with a first airflow parameter, driving the guiding unit 12 and the pressing unit 13 to move towards the soft bladder sleeve 41 at a second speed until L1≥L0; wherein the second speed is greater than the first speed. By increasing the moving speed during the process of the soft bladder sleeve 41 expanding with air supply, making its cross-section approach a circle, the pressing unit 13 can quickly seal the soft bladder sleeve 41, improving processing efficiency. At the same time, it avoids excessive airflow leakage that could cause the soft bladder sleeve 41 to expand unstablely due to drastic changes in internal air pressure, ensuring that the soft bladder sleeve 41 is in a suitable expansion state. It should be understood that the execution order of the assembly method of the bladder sleeve 40 at this time is step S10, step S20, step S40, and step S30 in sequence.

[0064] Further, based on the radial expansion of the soft sleeve 41 and the driving of the pressing unit 13 to move the clamping ring 42 to a set position, the pressing unit 13 and the guiding unit 12 are moved away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until the airflow supply stops, i.e., step S30. Step S30 includes steps S31 to S34:

[0065] Step S31: Based on L1≥L0, the air supply component 50 supplies airflow into the soft sleeve 41 with the second airflow parameter. The pressure of the first airflow parameter is lower than the pressure of the second airflow parameter, and the flow rate of the first airflow parameter is greater than the flow rate of the second airflow parameter. By adjusting the airflow parameters of the air supply component 50, a high-flow-rate, low-pressure airflow of the first airflow parameter is used when the soft sleeve 41 is not completely sealed to ensure expansion roundness; after the soft sleeve 41 is completely sealed, a low-flow-rate, high-pressure airflow of the second airflow parameter is used to slowly expand the soft sleeve 41, ensuring sufficient and uniform expansion.

[0066] In step S32, airflow is supplied into the soft sleeve 41 by the air supply assembly 50 with the second airflow parameters, and the second guide cone 123 unfolds. After unfolding, the minimum outer diameter of the second guide cone 123 is equal to the maximum outer diameter of the first guide cone 121. For example... Figure 3 As shown, the guiding unit 12 includes a first guiding cone 121, a second guiding cone 123, and a second driving part 122. One end of the first guiding cone 121 passes through the pressing unit 13 and is detachably connected to the pressing base unit 11, while the other end extends away from the pressing base unit 11. The inner peripheral wall of the pressing unit 13 is slidably connected to the first guiding cone 121. The second guiding cone 123 is located between the first guiding cone 121 and the pressing unit 13. The second guiding cone 123 is sleeved on the first guiding cone 121. The outer diameter of the end of the first guiding cone 121 away from the pressing unit 13 gradually decreases in the direction away from the pressing unit 13. The outer diameter of the end of the second guiding cone 123 away from the pressing unit 13 gradually decreases in the direction closer to the first guiding cone 121. This provides a guiding function. In addition to moving axially, the second guiding cone 123 can also expand or retract radially under the drive of the second driving part 122. Since the pressing unit 13 is sleeved on the first guide cone 121, there is a large difference in outer diameter between the first guide cone 121 and the pressing unit 13. By unfolding the second guide cone 123 and matching its size with the first guide cone 121, it is possible to avoid the inner wall of the soft bag sleeve 41 from rubbing against the side of the clamping ring 42 near the first guide cone 121 due to the stepped transition, thus protecting the soft bag sleeve 41. At the same time, after the second guide cone 123 is unfolded, it can clamp the clamping ring 42 with the pressing unit 13, ensuring that the clamping ring 42 is not affected by airflow and falls off during the pressing process, thereby improving the smoothness of the clamping ring 42 pressing the soft bag sleeve 41.

[0067] In step S33, based on the unfolding of the second guide cone 123, the driving guide unit 12 and the pressing unit 13 move toward the soft sleeve 41, causing the soft sleeve 41 to expand radially to a set diameter. This step ensures that the soft sleeve 41 expands to a diameter suitable for pressing the clamping ring 42, providing conditions for the accurate positioning of the clamping ring 42; and also avoids damage to the soft sleeve 41 due to excessive expansion.

[0068] Step S34: Based on the radial expansion of the soft sleeve 41 to a set diameter, the pressing unit 13 is driven to move the clamping ring 42 to a set position. The pressing unit 13 and the guiding unit 12 are then driven to move away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until it stops. By gradually reducing the airflow supply during the retraction process of the pressing unit 13 and the guiding unit 12 after the clamping ring 42 is in place, the soft sleeve 41 gradually retracts to surround the clamping ring 42, so that the clamping ring 42 has a fixed position relative to the soft sleeve 41. At the same time, the slow reduction of the airflow supply can prevent the soft sleeve 41 from contracting rapidly, reduce the interaction force between the soft sleeve 41 and the pressing unit 13 and the guiding unit 12, thereby reducing the friction between the pressing unit 13 and the guiding unit 12 and the inner peripheral wall of the soft sleeve 41, and improving the smoothness of retraction.

[0069] Furthermore, based on the deployment of the second guide cone 123, the driving guide unit 12 and the pressing unit 13 are moved toward the soft capsule sleeve 41, causing the soft capsule sleeve 41 to expand radially. That is, step S33 includes: based on the deployment of the second guide cone 123, driving the guide unit 12 and the pressing unit 13 to move toward the soft capsule sleeve 41 at a third speed, causing the soft capsule sleeve 41 to expand radially; wherein the third speed is less than the first speed. By slowing down the pressing speed of the guide unit 12 and the pressing unit 13, the risk of axial compression deformation of the soft capsule sleeve 41 can be reduced, ensuring its slow and uniform radial expansion and avoiding damage caused by drastic changes in internal air pressure.

[0070] Further, based on the fact that the soft sleeve 41 expands radially to a set diameter and the pressing unit 13 is driven to move the clamping ring 42 to a set position, the pressing unit 13 and the guiding unit 12 are driven to move away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until the airflow supply stops, which is step S34. Step S34 includes S341~S344:

[0071] S341, based on the radial expansion of the soft sleeve 41 to a set diameter, the guide unit 12 and the pressing unit 13 are driven to the concave position. By moving the guide unit 12 and the pressing unit 13 to the concave position, preparation can be made for the subsequent retraction of the second guide cone 123, ensuring a smooth operation process.

[0072] S342, based on the drive guide unit 12 and the pressing unit 13 to the concave cone position, the second guide cone 123 is retracted. The maximum diameter of the outer contour of the retracted second guide cone 123 is smaller than the inner diameter of the clamping ring 42. By retracting the second guide cone 123 and controlling its retraction size, obstruction to the movement of the clamping ring 42 can be avoided, providing space for the clamping ring 42 to reach the set position.

[0073] S343, based on the retraction of the second guide cone 123, the pressing unit 13 is driven to move the clamping ring 42 to the set position. By driving the pressing unit 13 after the second guide cone 123 retracts, it can be ensured that the clamping ring 42 moves accurately to the set position, avoiding the clamping ring 42 from being skewed due to interference from the guide structure.

[0074] S344, based on the driving pressure unit 13 to move the clamping ring 42 to a set position, the driving pressure unit 13 and the guiding unit 12 are moved away from the soft bag sleeve 41, and the air supply assembly 50 reduces the airflow supply until it stops. By gradually reducing the airflow supply during the retraction of the pressure unit 13 and the guiding unit 12 after the clamping ring 42 is in place, the soft bag sleeve 41 gradually retracts to surround and hold the clamping ring 42, so that the clamping ring 42 has a fixed position relative to the soft bag sleeve 41, avoiding the clamping ring 42 from being tilted due to the friction force pulling the soft bag sleeve 41 when the pressure unit 13 and the guiding unit 12 retract. At the same time, avoiding rapid contraction of the soft sleeve 41 and reducing the interaction force between the soft sleeve 41 and the pressing unit 13 and the guiding unit 12 can reduce the friction between the pressing unit 13 and the guiding unit 12 and the inner peripheral wall of the soft sleeve 41, improve the smoothness of withdrawal, avoid excessive interference of the pressing unit 13 on the soft sleeve 41, ensure the stable position of the clamping ring 42, and ensure a smooth pressing process.

[0075] Further, based on the drive guide unit 12 and the pressing unit 13 to the constricted cone position, the second guide cone 123 is retracted. The maximum diameter of the outer contour of the retracted second guide cone 123 is smaller than the inner diameter of the clamping ring 42. This is step S342. Step S342 includes steps S3421 and S3422:

[0076] In step S3421, based on the drive guiding unit 12 and the pressing unit 13 to the concave position, the air supply assembly 50 provides airflow into the soft sleeve 41 with a third airflow parameter; wherein the pressure of the third airflow parameter is greater than the pressure of the second airflow parameter. By increasing the airflow pressure supplied by the air supply assembly 50 when the guiding unit 12 and the pressing unit 13 are in the concave position, the expansion speed of the soft sleeve 41 in the concave position can be accelerated, thereby reducing the resistance of the pressing unit 13 to continue pressing down, making it easier for the clamping ring 42 to easily reach the set position. At the same time, it can avoid a sudden drop in air pressure inside the soft sleeve 41 when the guiding unit 12 retracts, ensuring its expansion uniformity and providing a stable expansion state for subsequent operations.

[0077] In step S3422, airflow is supplied into the soft sleeve 41 by the air supply component 50 with the third airflow parameter to retract the second guide cone 123. By retracting the second guide cone 123 at a higher air pressure, the influence of air pressure changes on the shape of the soft sleeve 41 can be reduced, ensuring a smooth retraction process and preventing the soft sleeve 41 from deforming due to air pressure fluctuations.

[0078] Further, based on the driving pressing unit 13 moving the clamping ring 42 to a set position, the driving pressing unit 13 and the guiding unit 12 move away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until the airflow supply stops. This is step S344. Step S344 includes steps S3441 and S3442:

[0079] In step S3441, the clamping ring 42 is moved to a set position by the driving pressing unit 13, and the third limiting unit 23 engages with the clamping ring 42. By engaging the third limiting unit 23 with the clamping ring 42, the position of the clamping ring 42 relative to the soft pouch 41 can be further fixed, preventing displacement or tilting of the clamping ring 42 during subsequent operations. The engagement of the third limiting unit 23 with the clamping ring 42 can be achieved by gripping with claws or by a limiting block abutting against the inner ring wall of the clamping ring 42.

[0080] In step S3442, based on the engagement connection between the third limiting unit 23 and the clamping ring 42, the pressing unit 13 and the guiding unit 12 are driven to move away from the soft sleeve 41, and the air supply assembly 50 reduces the airflow supply until it stops. By controlling the pressing unit 13 and the guiding unit 12 to withdraw and the airflow to gradually decrease after the clamping ring 42 is fixed by the third limiting unit 23, the soft sleeve 41 gradually contracts to stably hold the clamping ring 42, thus avoiding interference to the clamping ring 42 during the withdrawal of the pressing unit 13 and the guiding unit 12.

[0081] Furthermore, based on the engagement connection between the third limiting unit 23 and the clamping ring 42, the driving pressing unit 13 and the guiding unit 12 are moved away from the soft sleeve 41, causing the air supply assembly 50 to reduce the airflow supply until the airflow supply stops. This is step S3442. Step S3442 includes steps S34421 and S34422:

[0082] In step S34421, based on the engagement connection between the third limiting unit 23 and the clamping ring 42, the air supply assembly 50 reduces the airflow supply until it stops. By reducing and stopping the airflow supply, the soft sleeve 41 can gradually contract to tightly surround the clamping ring 42, enhancing the connection stability between the clamping ring 42 and the soft sleeve 41, and preventing the clamping ring 42 from tilting due to friction when the pressing unit 13 and the guiding unit 12 are subsequently withdrawn.

[0083] In step S34422, based on the reduction of airflow supply by the air supply assembly 50, the pressure unit 13 and the guide unit 12 are driven to move away from the soft sleeve 41; wherein, the air supply assembly 50 stops the airflow supply before the pressure unit 13 disengages from the soft sleeve 41. By driving the pressure unit 13 and the guide unit 12 to retract before the airflow stops, the rapid contraction of the soft sleeve 41 is avoided, the interaction force between the soft sleeve 41 and the pressure unit 13 and the guide unit 12 is reduced, the friction when the pressure unit 13 or the guide unit 12 disengages from the soft sleeve 41 is reduced, the risk of wear on the inner wall of the soft sleeve 41 is reduced, and the structure of the soft sleeve 41 is protected.

[0084] Example 2:

[0085] This embodiment discloses a capsule / skin assembly 40 assembly system, which is applied to the capsule / skin assembly method of any of the above embodiments. For example... Figure 2 As shown, the bladder assembly 40 assembly system includes a pressing assembly 10, a support assembly 20, a frame assembly 30, an air supply assembly 50, and a bladder assembly 40. Figure 2 , Figure 3 As shown, the pressing assembly 10 includes a pressing base unit 11, a guiding unit 12, and a pressing unit 13. The pressing base unit 11 includes a pressing base plate 111 and a first driving part 112. The guiding unit 12 includes a first guiding cone 121. One end of the first guiding cone 121 passes through the pressing unit 13 and is detachably connected to the pressing base plate 111, while the other end extends away from the pressing base plate 111. The pressing unit 13 may be a hollow cylindrical shape. The pressing unit 13 is detachably connected to the pressing base plate 111. The first driving part 112 drives the pressing base plate 111 to move axially along the pressing unit 13. The inner peripheral wall of the pressing unit 13 is slidably connected to the first guiding cone 121. By driving the pressing base plate 111 through the first driving part 112, the pressing unit 13 and the first guiding cone 121 are moved toward the support assembly 20, thereby pressing the clamping ring 42 into the soft pouch sleeve 41. The outer diameter of the first guide cone 121 gradually decreases towards the direction away from the pressing unit 13, forming a frustum shape, thus serving a guiding function. Through the structural design and driving method of each component, precise movement and deformation of the guide unit 12 and the pressing unit 13 can be achieved, ensuring the guiding and pressing effect on the soft sleeve 41 and the clamping ring 42, avoiding pressing jamming and curling of the soft sleeve 41. The support assembly 20 is spaced at the end of the first guide cone 121 away from the pressing unit 13. The support assembly 20 can fix and position the soft sleeve 41, ensuring its stable position during pressing and providing a reliable foundation for subsequent operations. The frame assembly 30 is detachably connected to the support assembly 20. The frame assembly 30 is also detachably connected to the pressing unit 11. This detachable connection between the frame assembly 30, the support assembly 20, and the pressing unit 11 facilitates equipment assembly, debugging, and maintenance, improving the system's flexibility and stability. Figure 10 As shown, the capsule assembly 40 includes a soft capsule sheath 41 and a clamping ring 42. (As indicated...) Figure 7 , Figure 8 As shown, the soft capsule 41 is a hollow cylindrical shape with openings at both ends. Figure 9 As shown, the clamping ring 42 is annular, and its cross-sectional shape can be rectangular, polygonal, or circular. The air supply assembly 50 supplies air to the soft capsule sleeve 41. Supplying air to the soft capsule sleeve 41 via the air supply assembly 50 allows the soft capsule sleeve 41 to expand and deform. Using an inflation method reduces damage to the soft capsule sleeve 41 and creates conditions for smooth press-fitting of the clamping ring 42. The capsule sleeve assembly 40 assembly system also includes a first state and a second state; the first state includes the support assembly 20 fixing and positioning the soft capsule sleeve 41, with the clamping ring 42 abutting against one end of the pressing unit 13 near the first guide cone 121; the second state includes the support assembly 20 and the pressing unit 13 respectively sealing both ends of the soft capsule sleeve 41, the soft capsule sleeve 41 expanding radially, and the clamping ring 42 being detachably connected to the inner peripheral wall of the soft capsule sleeve 41. By switching between the two states, a series of operations such as positioning, inflation, guiding, and placing and pressing the soft capsule 41 and the buckling ring 42 can be carried out in an orderly manner, ensuring a smooth assembly process and reducing jamming and damage.

[0086] Furthermore, such as Figure 3 As shown, the guiding unit 12 also includes a second guiding cone 123 and a second driving part 122. The second guiding cone 123 is sleeved on the outer peripheral wall of the end of the first guiding cone 121 away from the pressure base plate 111. The second driving part 122 drives the second guiding cone 123 to move radially thereafter. The outer diameter of the second guiding cone 123 gradually decreases in the direction away from the pressing unit 13, forming a frustum shape, which serves as a guide. When the second guiding cone 123 is unfolded, its maximum outer diameter is equal to the outer diameter of the clamping ring 42; when the second guiding cone 123 is folded, its maximum outer diameter is smaller than the inner diameter of the clamping ring 42. Figure 10 As shown, the inner peripheral wall of the soft sleeve 41 is detachably connected to the clamping ring 42. The detachable design of the soft sleeve 41 and the clamping ring 42, along with the dimensional matching between the second guide cone 123 and the clamping ring 42, facilitates assembly of both, ensures the compatibility of the clamping ring 42 with the soft sleeve 41 during press-fitting, and avoids interference of the second guide cone 123 with the press-fitting of the clamping ring 42.

[0087] Furthermore, such as Figure 2 , Figure 3As shown, the frame assembly 30 includes a base unit 31 and a support unit 32. The support unit 32 is mounted on the base unit 31. The support unit 32 can be two spaced-apart support columns. The base unit 31 is platform-shaped, with a support assembly 20 located in its central region. The two ends of the pressure plate 111 are slidably connected to the support unit 32. The first drive unit 112 drives the pressure plate 111 to move along the guide direction of the support unit 32. The pressure plate 111 is positioned directly above the support assembly 20. The side of the pressure plate 111 closest to the support assembly 20 is detachably connected to the end of the lower pressing unit 13 furthest from the support assembly 20. The lower pressing unit 13 includes a lower pressing sleeve 131 and a third drive unit 132. One end of the lower pressing sleeve 131 is detachably connected to the pressure plate 111. The lower pressing sleeve 131 can be hollow cylindrical, with its inner circumferential wall slidably connected to the guide unit 12 to facilitate the extension and retraction of the guide unit 12. The third drive unit 132 drives the lower pressing sleeve 131 to move along its own axial direction.

[0088] Furthermore, such as Figure 4 , Figure 5 , Figure 6As shown, the support assembly 20 includes a sealing unit 21, a second limiting unit 22, and a third limiting unit 23. The sealing unit 21 includes a central column 211, movable pressure blocks 212, a fourth driving part 213, and an air supply port 214. One end of the central column 211 is detachably connected to the base unit 31, and the other end extends towards the first guide cone 121. The central column 211 and the first guide cone 121 are coaxially spaced apart. Multiple movable pressure blocks 212 are spaced apart circumferentially along the central column 211, and the combined outline of the multiple movable pressure blocks 212 is annular. The fourth driving part 213 can drive the movable pressure blocks 212 to move towards or away from the axis of the central column 211. When the soft sleeve 41 is positioned, the soft sleeve 41 can be fitted onto the central column 211. The inner wall of the movable pressure block 212 and the outer peripheral wall of the central column 211 clamp the end of the soft sleeve 41 away from the first guide cone 121, thereby sealing the end of the soft sleeve 41 away from the first guide cone 121. The air supply hole 214 can penetrate the central column 211. The air supply hole 214 can connect the air supply assembly 50 with the internal space of the soft sleeve 41, so that the air supply assembly 50 supplies airflow to inflate the soft sleeve 41. The second limiting unit 22 includes a limiting tube 221 and a connecting tube 222. The limiting tube 221 and the connecting tube 222 are fixedly connected or detachably connected in sequence. The end of the connecting tube 222 away from the limiting tube 221 is detachably connected to the base unit 31. The limiting tube 221 and the connecting tube 222 are coaxial and sleeved on the outer peripheral side of the central column 211 and the movable pressure block 212. This limits the expansion of the lower half of the outer circumference of the soft pouch 41, and ensures that the end face of the limiting tube 221 away from the connecting tube 222 is adjacent to the set position of the clamping ring 42 within the soft pouch 41, preventing excessive downward pressure during clamping. The third limiting unit 23 includes a rotating rod 231, a swing arm 232, a locking part 233, and a fifth driving part 234. One end of the rotating rod 231 is detachably connected to the end of the central post 211 near the first guide cone 121. Multiple rotating rods 231 are spaced apart circumferentially along the central post 211. One end of the swing arm 232 is detachably connected to the end of the rotating rod 231 away from the central post 211, and the other end is connected to the locking part 233. The locking part 233 can be a contoured groove or a gripper, facilitating the positioning and fixing of the inner circumferential wall of the clamping ring 42. The fifth drive unit 234 drives the rotating rod 231 to rotate, thereby causing the swing arm 232 to move towards or away from the adjacent rotating rod 231. The axis of the swing arm 232 can be tangent to the circumferential surface of the rotating rod 231 or the central column 211.

[0089] Furthermore, such as Figure 2As shown, the air supply assembly 50 includes an air supply unit 51, a pressure regulating unit 52, and a flow regulating unit 53. The air supply unit 51, pressure regulating unit 52, and flow regulating unit 53 are respectively mounted on the frame assembly 30. The air supply unit 51 can communicate with the air supply port 214 to supply air to the soft sleeve 41. The pressure regulating unit 52 can adjust the pressure of the airflow supplied by the air supply unit 51, and the flow regulating unit 53 can adjust the flow rate of the airflow supplied by the air supply unit 51. The air supply unit 51 can be an air pump, and the pressure regulating unit 52 and flow regulating unit 53 can be electric valves.
