Description

Technical Field

[0001] This invention relates to the field of automated equipment technology, and more specifically, to a method and system for packaging dust covers. Background Technology

[0002] Conical corrugated dust covers are key protective devices used in the industrial field to protect precision moving parts such as hydraulic cylinders, machine tool guideways, and ball screws. They have a hollow conical structure with a retractable corrugated tube body, forming a large-diameter end and a small-diameter end at each end. Materials typically include polyurethane, nitrile rubber, nylon, or coated fabric. They combine elastic deformation capabilities with protection against impurities and liquid corrosion, and are widely used in engineering machinery, automated equipment, and machine tool processing. They require bulk packaging for warehousing and transportation.

[0003] In existing technologies, the packaging of conical corrugated pipe dust covers typically involves manual stacking or handling with general-purpose clamps. However, due to the tapered shape of the dust cover and the expansion and contraction of the corrugated pipe, this method has significant technical drawbacks. Firstly, the stacking process lacks a dedicated positioning structure, and the large-diameter and small-diameter ends of the dust cover lack a suitable support reference, making it prone to tipping and misalignment. Furthermore, the corrugated pipe folds are susceptible to irreversible deformation under stacking pressure, and direct contact and friction between adjacent dust cover surfaces can easily lead to coating scratches or wear on the fold edges. Secondly, the clamping and handling process relies on general-purpose flat clamps or end clamps. Flat clamps are difficult to adapt to the conical surface, easily causing slippage, while end clamps require significant rigidity to secure them, which can easily cause cracking at the large-diameter or small-diameter end interface of the dust cover or damage to the corrugated pipe folds. Therefore, automated packaging of dust covers is difficult, stacking and handling operations rely on a lot of manual intervention, resulting in low packaging efficiency and difficulty in adapting to the mass production needs of dust covers of different specifications. This makes the pre-processing stage before warehousing and transportation a bottleneck affecting production efficiency. At the same time, due to insufficient protection and positioning, there is a risk of deformation or scratches on the products during packaging. Summary of the Invention

[0004] To address the difficulty of automated packaging during the production of conical dust covers, this invention provides a dust cover packaging method and system.

[0005] Firstly, this application proposes a method for packaging dust covers:

[0006] Multiple dust covers are stacked and fitted onto the outer periphery of the support rod; wherein, the dust cover is configured as a hollow structure; the large-diameter end of the first fitted dust cover abuts against the support base connected to the end of the support rod; the subsequent fitted dust covers are fitted onto the outer periphery of the small-diameter end of the previous dust cover.

[0007] Drive the support rod to flip to a first state; the first state includes an angle between the central axis of the support rod and the horizontal plane that is less than or equal to a set angle;

[0008] A set of second gripping claws is driven to an open state, and at least one set of first gripping claws and a set of second gripping claws are driven to move toward a first position towards the dust cover; wherein, the open state includes the second gripping claws being spaced apart from the dust cover during their movement; the first position includes a set of first gripping claws at least partially surrounding the dust cover, and the free ends of the first gripping claws passing below the horizontal plane where the maximum diameter of the dust cover is located; the dust cover is deformed during the movement of the first gripping claws to the first position;

[0009] Drive a set of second gripping claws to clamp onto the conical surface of the outermost dust cover;

[0010] The first and second gripping claws are driven to move the multiple dust covers into the housing.

[0011] In some embodiments, driving a set of second gripping claws to an open state and driving at least one set of first gripping claws and a set of second gripping claws to move toward a first position toward the dust cover includes:

[0012] Based on the support rod flipping to the first state, the driving clamping ring squeezes the dust cover away from the support base to a first set position;

[0013] Based on the clamping ring pressing the dust cover away from the support to a first set position, a set of second clamping claws is driven to an open state and at least a set of first clamping claws and a set of second clamping claws are driven to move toward the dust cover to a first position.

[0014] In some embodiments, driving a set of second gripping claws to clamp onto the conical surface of the outermost dust cover includes:

[0015] Based on at least one set of first clamping claws and one set of second clamping claws moving toward the dust cover to a first position, the clamping ring is driven to move away from the dust cover, causing the dust cover to move to a second set position; wherein, in the second set position, the clamping ring abuts against the dust cover, and the first set position is located between the second set position and the support base;

[0016] Based on the dust cover moving to the second set position, a set of the second clamping claws are driven to clamp onto the outermost conical surface of the dust cover.

[0017] In some embodiments, the dust cover includes a first locking ring, a second locking ring, and a conical corrugated pipe; the first locking ring is coaxially connected to the small-diameter end of the conical corrugated pipe; the second locking ring is coaxially connected to the large-diameter end of the conical corrugated pipe.

[0018] The first set of second gripping claws is driven to the open state, and at least one set of first gripping claws and one set of second gripping claws are driven to move toward the first position in the direction of approaching the dust cover:

[0019] The first position includes a set of two free ends of the first clamping claw located in the recess of the conical bellows.

[0020] In some embodiments, the step of driving a set of second gripping claws to clamp onto the outermost conical surface of the dust cover based on the dust cover being moved to a second predetermined position includes:

[0021] Based on the dust cover moving to the second set position, a set of the second clamping claws are driven to clamp onto the outermost conical surface of the dust cover;

[0022] Based on the second clamping claw clamping onto the conical surface of the outermost dust cover, the clamping ring is driven to reciprocate along the axial direction of the support rod at a set distance.

[0023] In some embodiments, driving the first gripping claw and the second gripping claw to transport the plurality of dust covers into the housing includes:

[0024] Based on the second clamping claw clamping onto the conical surface of the outermost dust cover, the clamping ring is driven to disengage from the support rod, and the support rod is driven to be pulled out from the inner hole of the dust cover;

[0025] Based on the fact that the support rod is pulled out from the inner hole of the dust cover, the first clamping claw and the second clamping claw are driven to transport the multiple dust covers to the unloading position of the box;

[0026] Based on the dust cover being transported to the unloading position of the box, the second clamping claw is driven to the unloading state, and the unloading rod drives the dust cover to separate from the first clamping claw; wherein, the unloading state includes the second clamping claw being spaced apart from the dust cover.

[0027] In some embodiments, the step of driving the clamping ring to disengage from the support rod and driving the support rod to be pulled out of the inner hole of the dust cover based on the second clamping claw clamping on the conical surface of the outermost dust cover includes:

[0028] Based on the second clamping claw clamping onto the conical surface of the outermost dust cover, the clamping ring is driven to disengage from the support rod;

[0029] Based on the fact that the clamping ring disengages from the support rod, the first clamping claw and the second clamping claw are driven to lift the dust cover up to a distance between the inner wall of the dust cover and the support rod.

[0030] In some embodiments, the process involves moving the dust cover to the unloading position of the housing, driving the second clamping claw to the unloading state, and the unloading rod driving the dust cover to separate from the first clamping claw.

[0031] The unloading state also includes a ring whose minimum outer diameter is smaller than the maximum outer diameter of the dust cover, where the two free ends of the second clamping claw are located.

[0032] In some embodiments, the drive to flip the support rod to the first state is as follows:

[0033] The first state also includes the support rod being tilted downwards at one end connected to the support base relative to the other end.

[0034] In a first aspect, this application proposes a dust cover packaging system, which is applied to any of the dust cover packaging methods described in the first aspect. The dust cover packaging system includes:

[0035] Frame components;

[0036] A housing; the housing is disposed on the frame assembly; the housing has a receiving space and an upward-facing opening; the opening communicates with the receiving space;

[0037] A flipping assembly includes a flipping base, a flipping unit, and a support unit. The support unit includes a support seat and a support rod. The support seat is connected to one end of the support rod. The flipping base is connected to the frame assembly. The flipping unit is rotatably connected to the flipping base. The support seat is drivenly connected to the flipping unit.

[0038] The gripping unit includes a gripping seat, a first clamping module, and a second clamping module; the gripping seat is movably connected to the frame assembly; the first clamping module includes multiple first clamping seats and multiple sets of first clamping claws; the second clamping module includes a first driving part, at least one second clamping seat, and at least one set of second clamping claws;

[0039] The first clamping seat is connected to the gripping seat; multiple first clamping seats are arranged sequentially at intervals; the movable end of each group of first clamping claws is connected to one first clamping seat in turn;

[0040] The second clamping seat and the first driving part are respectively connected to the gripping seat; the second clamping claw is movably connected to the second clamping seat, and the second clamping claw is driven connected to the first driving part; the first driving part includes a driving state; the driving state includes: the first driving part drives the second clamping claw to open or clamp.

[0041] To solve the problem of difficult automatic packaging during the production of conical dust covers, this invention has the following advantages:

[0042] The support rod serves as the internal support frame of the hollow dust cover. The large-diameter end of the first dust cover abuts against the support seat to form axial positioning. Subsequent dust covers are nested one by one into the outer periphery of the small-diameter end of the previous dust cover. Through the dual reference of internal support and external embedding, all dust covers are stacked coaxially along the axis of the support rod, which can avoid tipping and misalignment during the stacking process and lay a stable foundation for subsequent batch handling.

[0043] After the drive support rod flips to the point where the angle between the central axis of the support rod and the horizontal plane is less than or equal to the set angle, multiple dust covers unfold, and the first gripper can more easily extend between adjacent dust covers, avoiding difficulty in gripper alignment caused by posture restrictions.

[0044] After multiple dust covers are stacked, the overall structure roughly consists of cylindrical and conical sections. Multiple sets of first clamping claws move towards the cylindrical section and, through the deformation of the dust cover, pass through the horizontal plane containing the maximum diameter of the dust cover, thus clamping the cylindrical section. Second clamping claws then move towards the conical section. Due to the varying diameter of the conical section, opening the second clamping claws and then clamping the conical section in subsequent steps avoids damage to the conical section caused by rigid contact between the second clamping claws and the conical section. Active clamping is achieved by clamping the second clamping claws, which can adapt to different outer diameters of the dust covers. Stable stacking, flexible clamping, and adaptation to the conical surface completely solve problems such as deformation, scratches, and cracking. This allows for the efficient handling of intact batches of dust covers into the box, significantly reducing the defect rate after packaging. Attached Figure Description

[0056] Due to its tapered shape and the expansion and contraction of the corrugated tube, the dust cover 40 is prone to tipping and misalignment during the packaging and stacking process because it lacks a dedicated positioning structure. Furthermore, the large-diameter end and small-diameter end of the dust cover 40 lack a matching support reference. The corrugated tube folds are also prone to irreversible deformation under stacking pressure. Additionally, direct contact and friction between adjacent dust cover 40 surfaces can easily lead to coating scratches or wear on the fold edges. Moreover, the dust cover 40 relies on general-purpose flat clamps or end clamps for clamping and handling. Flat clamps are difficult to adapt to the tapered surface, easily causing slippage, while end clamps require a large rigid force to fix it, which can easily cause cracking at the large-diameter or small-diameter end interface of the dust cover 40 or damage to the corrugated tube folds. Therefore, automated packaging of dust covers 40 is difficult, stacking and handling operations rely on a lot of manual intervention, resulting in low packaging efficiency and difficulty in adapting to the mass production needs of different specifications of dust covers 40. This makes the pre-processing stage before warehousing and transportation a bottleneck affecting production efficiency. At the same time, due to insufficient protection and positioning, the products are likely to be deformed or scratched during the packaging process.

[0057] Example 1:

[0058] This embodiment proposes a method for packaging dust covers, such as... Figure 1 As shown, it includes steps S10-S50.

[0059] Step S10: Stack multiple dust covers 40 and fit them around the outer periphery of the support rod 134. Each dust cover 40 is a hollow structure. The large-diameter end of the first dust cover 40 abuts against the support base 131 connected to the end of the support rod 134. Subsequent dust covers 40 are fitted one-to-one around the small-diameter end of the preceding dust cover 40. The support rod 134 serves as the internal support frame for the hollow dust covers 40. The large-diameter end of the first dust cover 40 abuts against the support base 131 for axial positioning. Subsequent dust covers 40 are nested around the small-diameter end of the preceding dust cover 40. Through this dual reference of internal support and external embedding, all dust covers 40 are coaxially stacked along the axis of the support rod 134, preventing tipping and misalignment during stacking and providing a stable foundation for subsequent batch handling.

[0060] Step S20: Drive the support rod 134 to flip to the first state; the first state includes an angle less than or equal to a set angle between the central axis of the support rod 134 and the horizontal plane. If the support rod 134 remains vertical, the lower dust cover 40 will bear greater weight and deform more severely, which may prevent the first gripping claw 2222 from extending into the gap between two adjacent dust covers 40. After flipping, the multiple dust covers 40 unfold, and the first gripping claw 2222 can more easily extend into the gap between adjacent dust covers 40, avoiding positioning difficulties of the first gripping claw 2222 due to posture limitations. In some embodiments, the set angle is less than or equal to 20°, for example, the set angle can be 0°, 5°, 10° or 15°.

[0061] Step S30: Drive a set of second gripping claws 2232 to the open state and drive at least a set of first gripping claws 2222 and a set of second gripping claws 2232 to move toward a first position in the direction of approaching the dust cover 40; wherein, the open state includes the second gripping claws 2232 being spaced apart from the dust cover 40 during the movement; the first position includes the first gripping claws 2222 at least partially surrounding the dust cover 40, and the free ends of the first gripping claws 2222 passing below the horizontal plane where the maximum diameter of the dust cover 40 is located; the dust cover 40 is deformed during the movement of the first gripping claws 2222 to the first position. After multiple dust covers 40 are stacked, the overall structure is roughly cylindrical and conical. Multiple sets of first clamping claws 2222 move toward the cylindrical section and pass through the horizontal plane where the maximum diameter of the dust cover 40 is located by the deformation of the dust cover 40, thereby clamping the cylindrical section and moving the second clamping claws 2232 toward the conical section. Due to the different diameter structure of the conical section, by opening the second clamping claws 2232 and clamping the conical section in subsequent steps, the rigid contact between the second clamping claws 2232 and the conical section can be avoided, thus preventing the conical section from being damaged due to rigid contact.

[0062] Step S40: Drive a set of second clamping claws 2232 to clamp onto the conical surface of the outermost dust cover 40. Active clamping is achieved by clamping the second clamping claws 2232, which can be adapted to clamp parts of the dust cover 40 with different outer diameters.

[0063] Step S50: Drive the first gripper 2222 and the second gripper 2232 to move multiple dust covers 40 to the box 50. The previous steps have solved problems such as deformation, scratches and cracks through stable stacking, flexible clamping and adapting conical surfaces. Step S50 moves the intact batch of dust covers 40 to the box 50, which can reduce the defect rate after packaging.

[0064] Furthermore, step S30 includes steps S31 and S32.

[0065] Step S31: Based on the support rod 134 flipping to the first state, drive the clamping ring 32 to press the dust cover 40 away from the support base 131 to the first set position. Although the nested stacking in the previous steps can achieve coaxial positioning, due to the elastic characteristics of the corrugated pleats of the dust cover 40, there may be a small axial gap between adjacent dust covers 40. Or due to the effect of the flipping of the support rod 134, the stacked dust covers 40 may be displaced due to inertia, resulting in inconsistent gaps between the multiple dust covers 40. The clamping ring 32 actively presses the dust cover 40 away from the support base 131 to the first set position, which can eliminate these gaps through pressure, facilitate the positioning of the gap between the first clamping claw 2222 and the dust cover, and facilitate the subsequent clamping of the dust cover by the first clamping claw 2222 to improve the stability of the dust cover during transportation.

[0066] Step S32: Based on the compression ring 32 pressing the dust cover 40 away from the support base 131 to the first set position, drive a set of second clamping claws 2232 to the open state and drive at least a set of first clamping claws 2222 and a set of second clamping claws 2232 to move towards the dust cover 40 to the first position. After being compressed by the compression ring 32, the stacked shape of the multiple dust covers 40 is more regular. When the first clamping claw 2222 moves to the first position, its contact point with the dust cover 40 and the direction of force can be precisely matched with the gap between adjacent dust covers 40.

[0067] Furthermore, step S40 includes:

[0068] Step S41: Based on at least one set of first clamping claws 2222 and one set of second clamping claws 2232 moving towards the dust cover 40 to a first position, the clamping ring 32 is driven to move away from the dust cover 40, causing the dust cover 40 to move to a second set position. In the second set position, the clamping ring 32 abuts against the dust cover 40. The first set position is located between the second set position and the support base 131. If the clamping force of the second clamping claws 2232 is limited, and if the clamping position of the second clamping claws 2232 is biased towards the smaller diameter end of the dust cover 40, it may slip due to insufficient friction, resulting in unstable clamping. During the process of the dust cover 40 moving to the second set position, the compression between the dust cover 40 decreases, causing the larger outer diameter portion of the conical surface to move towards the second clamping claws 2232.

[0069] Step S42: Based on the dust cover 40 moving to the second preset position, a set of second clamping claws 2232 are driven to clamp onto the conical surface of the outermost dust cover 40. The clamping claws clamping the larger outer diameter portion creates a larger contact area, generating greater friction between the dust cover 40 and the second clamping claws 2232. This allows the second clamping claws 2232 to stably hold the conical surface of the dust cover 40, thereby reducing the risk of the dust cover 40 falling off during handling.

[0070] Furthermore, the dust cover 40 includes a first locking ring 41, a second locking ring 43, and a conical corrugated pipe 42; the first locking ring 41 is coaxially connected to the small-diameter end of the conical corrugated pipe 42; and the second locking ring 43 is coaxially connected to the large-diameter end of the conical corrugated pipe 42.

[0071] In step S30, the first position includes two free ends of a set of first gripping claws 2222 located in the recess of the conical bellows 42. The sidewall of the recess will abut against the first gripping claws 2222, forming an axial constraint force on the dust cover 40, ensuring that the stacked dust covers 40 do not undergo relative displacement during handling.

[0072] Further, step S42 includes steps S421 and S422.

[0073] Step S421: Based on the dust cover 40 moving to the second set position, drive a set of second clamping claws 2232 to clamp on the conical surface of the outermost dust cover 40.

[0074] Step S422: Based on the second clamping claw 2232 clamping on the conical surface of the outermost dust cover 40, drive the clamping ring 32 to reciprocate along the axis of the support rod 134 at a set distance. If the second clamping claw 2232 is only clamped on the top of the fold and does not fall into the groove of the bellows, the clamping will loosen due to the small contact area and insufficient friction. The reciprocating motion of the clamping ring 32 along the axis can drive the entire stacked dust cover 40 to move slightly axially. Utilizing the elastic deformation of the bellows, the contact position between the second clamping claw 2232 and the conical surface is axially fine-tuned. During the reciprocating motion, the clamping claw will be engaged in the nearest groove due to the resistance of the groove, avoiding the second clamping claw 2232 being clamped on the top of the fold, which would cause slippage and unstable clamping.

[0075] Furthermore, step S50 includes steps S51, S52, and S53.

[0076] Step S51: Based on the second clamping claw 2232 clamping onto the conical surface of the outermost dust cover 40, drive the clamping ring 32 to disengage from the support rod 134, and drive the support rod 134 to be pulled out from the inner hole of the dust cover 40. The support rod 134 serves as the inner skeleton for stacking dust covers 40. Although it achieves coaxial positioning, if it is not pulled out during packing, it may lead to subsequent packing complications. At the same time, pulling out the support rod facilitates its support for the dust covers 40 that need to be stacked later.

[0077] Step S52: Based on the support rod 134 being pulled out from the inner hole of the dust cover 40, the first clamping claw 2222 and the second clamping claw 2232 are driven to transport multiple dust covers 40 to the unloading position of the box 50. Compared with manual handling of dust covers 40 to box 50, which is prone to tilting due to visual errors, the first clamping claw 2222 and the second clamping claw 2232 are driven by a preset program, which can accurately transport the stacked units to the unloading position, ensuring that the relative position of the dust cover 40 and the box 50 meets the preset requirements, maximizing the use of the internal space of the box, and laying the foundation for the subsequent stable stacking of the box 50.

[0078] Step S53: Based on the dust cover 40 being transported to the unloading position of the box 50, the second gripping claw 2232 is driven to the unloading state, and the unloading rod 2242 drives the dust cover 40 to separate from the first gripping claw 2222; wherein, the unloading state includes the second gripping claw 2232 being spaced apart from the dust cover 40. The second gripping claw 2232 initially maintains a distance from the dust cover 40 to prevent the dust cover 40 from opening the second gripping claw 2232 during unloading, thus avoiding damage to the active opening and closing structure of the second gripping claw 2232. The entire unloading process does not require manual contact with the dust cover 40, avoiding contamination of the dust cover 40 by oil and impurities from human hands, reducing the uncertainty of manual operation, and realizing full automation of the packaging and boxing process.

[0079] Furthermore, step S51 includes steps S511 and S512.

[0080] Step S511: Based on the second clamping claw 2232 clamping on the conical surface of the outermost dust cover 40, drive the clamping ring 32 to disengage from the support rod 134.

[0081] Step S512 is based on the clamping ring 32 disengaging from the support rod 134, driving the first clamping claw 2222 and the second clamping claw 2232 to lift the dust cover 40 to a distance between the inner wall of the dust cover 40 and the support rod 134.

[0082] If the support rod 134 is pulled out directly, the friction between the support rod 134 and the dust cover 40 may cause the dust cover 40 to move, which may disrupt the engagement between the first clamping claw 2222, the second clamping claw 2232 and the dust cover 40. After the support rod 134 is pulled out with almost no resistance, it will not exert any additional force on the stacking unit, ensuring that the dust cover 40 remains in a compact stacked state throughout the process of pulling out the support rod 134, and avoiding disintegration or misalignment due to external interference.

[0083] Furthermore, in step S53:

[0084] The unloading state also includes the fact that the minimum outer diameter of the ring containing the two free ends of the second clamping claw 2232 is smaller than the maximum outer diameter of the dust cover 40. If the outer diameter of the ring containing the two free ends of the second clamping claw 2232 is larger than the maximum outer diameter of the dust cover 40 after the second clamping claw 2232 is opened, the outer side of the clamp is likely to come into direct contact and rub against the inner wall of the box 50 during unloading. This is especially true when the box 50 is made of easily damaged materials such as cardboard or plastic boxes, which can easily cause scratches and damage to the side wall of the box 50. The fact that the minimum outer diameter of the ring containing the two free ends of the second clamping claw 2232 is smaller than the maximum outer diameter of the dust cover 40 means that after the clamping claw is opened, its outermost contour is always within the range of the maximum outer diameter of the dust cover 40. During unloading, the clamping claw is always separated from the inner wall of the box 50 by the dust cover 40 and will not come into direct contact, avoiding the risk of the outer side of the clamping claw scratching the box 50 and ensuring the structural integrity of the box 50.

[0085] Furthermore, in step S20:

[0086] The first state also includes one end of the support rod 134 connected to the support base 131 being tilted downwards relative to the other end. In this way, the dust cover 40 naturally moves towards the support base 131 along the tilt direction, forming a self-pressurizing effect. This can prevent the dust cover 40 from sliding outwards along the support rod 134 due to its own weight, which would cause multiple dust covers 40 to disperse. This makes it easier to clamp multiple dust covers 40 subsequently using the first clamping claw 2222 and the second clamping claw 2232.

[0087] Example 2:

[0088] This embodiment proposes a dust cover packaging system; the dust cover packaging system is applied to any of the dust cover packaging methods in Embodiment 1. For example... Figure 2 As shown, the dust cover packaging system includes a frame assembly 60, a box 50, a flipping assembly 10, and a gripping unit 22. The box 50 is mounted on the frame assembly 60; the box 50 has a receiving space and an upward-facing opening; the opening communicates with the receiving space. The upward-facing opening design provides an unobstructed passage for the unloading operation of the gripping unit 22, avoiding unloading interference caused by side openings and improving packing efficiency.

[0089] The flipping assembly 10 includes a flipping base 11, a flipping unit 12, and a support unit 13. The support unit 13 includes a support seat 131 and a support rod 134. The support seat 131 is connected to one end of the support rod 134. The flipping base 11 is connected to the frame assembly 60. The flipping unit 12 is rotatably connected to the flipping base 11. The support seat 131 is drivenly connected to the flipping unit 12. The support rod 134 is adapted to the hollow structure of the dust cover 40, allowing multiple dust covers 40 to be coaxially nested, avoiding tipping or misalignment that may occur due to manual stacking. Figure 2 and Figure 3 As shown, the flipping unit 12 is rotatably connected to the flipping base 11, and the flipping unit 12 can drive the support rod 134 to flip to the first state.

[0090] like Figure 5 and Figure 6 As shown, the gripping unit 22 includes a gripping seat 221, a first clamping module 222, and a second clamping module 223; the gripping seat 221 is movably connected to the frame assembly 60; the first clamping module 222 includes multiple first clamping seats 2221 and multiple sets of first clamping claws 2222; the second clamping module 223 includes a first driving part 2233, at least one second clamping seat 2231, and at least one set of second clamping claws 2232.

[0091] The first clamping seat 2221 is connected to the gripping seat 221; multiple first clamping seats 2221 are arranged sequentially at intervals; the movable end of each set of first gripping claws 2222 is connected to one first clamping seat 2221. Multiple first clamping seats 2221 are arranged at intervals along the gripping seat 221, and multiple sets of first gripping claws 2222 are connected in a one-to-one correspondence, which can form a multi-point semi-encirclement of the stacked dust cover 40, which can disperse the clamping force and avoid corrugated pipe wrinkling damage caused by local stress concentration.

[0092] The second clamping seat 2231 and the first driving unit 2233 are respectively connected to the gripping seat 221; the second clamping claw 2232 is movably connected to the second clamping seat 2231, and the second clamping claw 2232 is drivenly connected to the first driving unit 2233; the first driving unit 2233 includes a driving state; the driving state includes: the first driving unit 2233 drives the second clamping claw 2232 to open or clamp. The first driving unit 2233 and the second clamping claw 2232 are drivenly connected, which can precisely control the clamping force and adapt to the conical surface of the dust cover 40 for clamping. At the same time, the automated control of the driving unit replaces manual adjustment, which can improve work efficiency. Then, the first clamping claw 2222 and the second clamping claw 2232 can transport multiple dust covers 40 to the box 50. Through stable stacking, flexible clamping, and adaptation to the conical surface, the problems of deformation, scratches, and cracks are completely solved, and the intact batch of dust covers 40 can be transported to the box 50, which can significantly reduce the defect rate after packaging.

[0093] In other embodiments, such as Figure 4 As shown, the flipping unit 12 includes a second drive unit 121 and a flipping unit 122; the flipping unit 122 is rotatably connected to the flipping base 11; the flipping unit 122 is drivenly connected to the second drive unit 121; and the support base 131 is connected to the flipping unit 122. If the flipping relies on manual flipping or a flipping structure without power drive, the tilt angle of the dust cover 40 will have random errors due to operating force, equipment wear, etc., resulting in difficulty in aligning the gripper claws later. The second drive unit 121 can be programmed to set a precise flipping angle to ensure that the dust cover 40 is in a preset tilted posture with the support base 131 facing downwards after flipping.

[0094] In other embodiments, such as Figure 4 As shown, the support unit 13 also includes a sliding part 132 and a third driving part 133. The sliding part 132 is movably connected to the flipping part 122; the sliding part 132 is drivenly connected to the third driving part 133; the support base 131 is connected to the sliding part 132. The movable connection between the sliding part 132 and the flipping part 122 can constrain the extraction path of the support rod 134, ensuring that the movement trajectory strictly coincides with the axis of the inner hole of the dust cover 40.

[0095] In other embodiments, such as Figure 2 and Figure 3As shown, the dust cover packaging system also includes a handling component 20; the handling component 20 includes a moving unit 21 and a gripping unit 22; the moving unit 21 includes a first translation module 211, a second translation module 212, a vertical translation module 213, and a rotation module 214. The first translation module 211 is movably connected to the frame assembly 60 along the x-axis; the second translation module 212 is movably connected to the first translation module 211 along the y-axis; the vertical translation module 213 is connected to the second translation module 212 along the z-axis; the rotation module 214 is rotatably connected to the vertical translation module 213; and the gripping seat 221 is connected to the rotation module 214. The four-dimensional movement of the moving unit 21 along the x-axis, y-axis, z-axis, and rotation allows the gripping unit 22 to cover all key workstations on the frame, enabling automatic packing without manual movement of the box 50 or adjustment of the frame.

[0096] In other embodiments, the first clamping module 222 includes a spring-back portion 2223; the free end of the first clamping claw 2222 is connected to the spring-back portion 2223; the spring-back portion 2223 has an elastic deformation capable of driving the first clamping claw 2222 to a reset position; the reset position includes: the distance between the two free ends of a set of first clamping claws 2222 is greater than the outer diameter of the support rod 134 and less than the outer diameter of the horizontal plane where the maximum diameter of the dust cover 40 is located. This allows the first clamping claw 2222 to elastically deform when it contacts the dust cover 40, thereby partially enclosing the dust cover 40, and then the elastic reset capability of the spring-back portion 2223 causes the free end of the first clamping claw 2222 to abut against the dust cover 40, thereby clamping the dust cover 40.

[0097] In other embodiments, such as Figure 5 and Figure 6 As shown, the gripping unit 22 includes an unloading module 224; the unloading module 224 includes a fourth drive unit 2241 and an unloading rod 2242; the fourth drive unit 2241 is connected to the gripping seat 221; the unloading rod 2242 is movably connected to the fourth drive unit 2241; the fourth drive unit 2241 is used to drive the unloading rod 2242 to squeeze the dust cover 40 out of the gripping space of the first gripping claw 2222 and the gripping space of the second gripping claw 2232. After the second gripping claw 2232 moves to the unloading state, the first gripping claw 2222 clamps the dust cover 40 by friction and the rebound force of the spring member, and then the unloading rod 2242 squeezes the dust cover 40 to overcome the friction between the first gripping claw 2222 and the dust cover 40 and the elastic force of the spring member 2223, pushing the dust cover 40 out into the box 50 to complete the packaging and transfer.

[0098] In other embodiments, such as Figure 2 and Figure 3As shown, the dust cover packaging system also includes a clamping assembly 30, which includes a fifth drive unit 31 and a clamping ring 32; the fifth drive unit 31 is connected to the frame assembly 60; and the clamping ring 32 is drivenly connected to the fifth drive unit 31.

[0099] In other embodiments, such as Figure 7 As shown, the dust cover 40 includes a first locking ring 41, a second locking ring 43, and a conical corrugated pipe 42; the first locking ring 41 is coaxially connected to the small-diameter end of the conical corrugated pipe 42; the second locking ring 43 is coaxially connected to the large-diameter end of the conical corrugated pipe 42.

[0100] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
