Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a dust cover packing method and system. BACKGROUND

[0002] The conical bellows dust cover is a key protective device for protecting precision moving parts such as hydraulic oil cylinders, machine tool guide rails, and ball screws in the industrial field. The overall structure is a hollow conical structure, the cover body is a telescopic bellows shape, and the two ends form a large-diameter end and a small-diameter end with different diameters, respectively. The material is mainly polyurethane, nitrile rubber, nylon or rubber-coated cloth, etc., which has elastic deformation ability and protective performance of preventing impurities and liquid erosion. It is widely used in engineering machinery, automation equipment, machine tool processing and other scenes, and needs to be packed in batches to realize storage and transportation.

[0003] In the prior art, the packing of the conical bellows dust cover is usually carried out by manual stacking or general clamp handling. Due to the structural characteristics of the conical dust cover and the telescopic bellows, such methods have obvious technical defects. On the one hand, the stacking process lacks a special positioning structure, and the large-diameter end and the small-diameter end of the dust cover have no adaptive support reference, which is prone to tilting and mispositioning. The bellows creases are prone to irreversible deformation under the pressure of stacking, and the surfaces of adjacent dust covers are in direct contact and friction, which is prone to scratching the coating or wearing the crease edges. On the other hand, the clamping and handling process relies on general plane clamps or end clamps. The plane clamp is difficult to adapt to the conical surface and is prone to slipping. The end clamp needs to exert a large rigid force to fix it, which is prone to cause the interface of the large-diameter end or the small-diameter end of the dust cover to crack or the bellows creases to be damaged. Therefore, the automatic packing of the dust cover is difficult, and the stacking and handling operations rely on a large amount of manual intervention, which is low in packing efficiency and difficult to adapt to the batch production needs of dust covers of different specifications, resulting in the preprocessing link before storage and transportation becoming a bottleneck affecting production efficiency. At the same time, due to the lack of protection and positioning, the dust cover is prone to deformation or scratching during packing. SUMMARY

[0056] The dust cover 40 is prone to tilting and mispositioning due to the lack of a special positioning structure in the stacking process during the packaging process. The large-diameter end and the small-diameter end of the dust cover 40 do not have a matching support reference, and the corrugated tube is prone to irreversible deformation under the pressure of stacking. In addition, the dust cover 40 relies on a general plane clamp or an end clamp during the clamping and carrying process. The plane clamp is difficult to adapt to the conical surface, and the end clamp needs to exert a large rigid force to be fixed, which may cause the large-diameter end or the small-diameter end of the dust cover 40 to crack or the corrugated tube to be damaged. Therefore, the dust cover 40 is difficult to be automatically packaged, and the stacking and carrying operations rely on a large amount of manual intervention, resulting in low packaging efficiency and difficulty in adapting to the batch production needs of dust covers 40 of different specifications. The preprocessing link before warehousing and transportation becomes a bottleneck affecting production efficiency, and the product is prone to deformation or scratching during the packaging process due to insufficient protection and positioning.

[0057] Embodiment one:

[0058] The embodiment provides a dust cover packaging method, as shown in Figure 1 The method comprises steps S10-S50.

[0059] Step S10: stack a plurality of dust covers 40 on the outer circumferential side of the support rod 134; wherein the dust cover 40 is provided in a hollow structure; the large-diameter end of the first stacked dust cover 40 abuts against the support seat 131 connected to the end of the support rod 134; and the small-diameter end of the subsequent stacked dust cover 40 is correspondingly arranged on the outer circumferential side of the small-diameter end of the previous dust cover 40. The support rod 134 serves as an internal support framework of the hollow dust cover 40, the large-diameter end of the first dust cover 40 abuts against the support seat 131 to form axial positioning, and the small-diameter end of the subsequent dust cover 40 is nested on the outer circumferential side of the small-diameter end of the previous dust cover 40. Through the double reference of internal support and external nesting, all the dust covers 40 are coaxially stacked along the axial line of the support rod 134, which can avoid tilting and mispositioning during stacking and lay a stable foundation for subsequent batch carrying.

[0060] Step S20: drive the support rod 134 to flip to a first state; the first state includes an included angle between the central axis of the support rod 134 and the horizontal plane being less than or equal to a set angle. If the support rod 134 remains vertical, the lower the dust cover 40, the greater the gravity it bears, and the more serious the deformation, which may cause the first clamping jaw 2222 to fail to extend into the gap between the adjacent two dust covers 40. After flipping, the plurality of dust covers 40 are stretched out, and the first clamping jaw 2222 can more easily extend into the gap between the adjacent two dust covers 40, avoiding the difficulty of aligning the first clamping jaw 2222 due to the posture limitation. 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 clamping jaws 2232 to an open state and drive at least a set of first clamping jaws 2222 and a set of second clamping jaws 2232 to move towards the dust cover 40 to a first position; wherein the open state includes that the second clamping jaw 2232 is spaced apart from the dust cover 40 during movement; the first position includes that the set of first clamping jaws 2222 at least semi-encloses the dust cover 40, and the free end of the first clamping jaw 2222 passes below the horizontal plane where the maximum diameter of the dust cover 40 is located; the first clamping jaw 2222 moves to the first position to deform the dust cover 40. After the dust covers 40 are stacked, the overall structure is approximately a cylindrical segment and a conical segment. The multiple sets of first clamping jaws 2222 move towards the cylindrical segment and pass through the horizontal plane where the maximum diameter of the dust cover 40 is located through the deformation of the dust cover 40, thereby clamping the cylindrical segment. The second clamping jaw 2232 moves towards the conical segment. Due to the different diameter structure of the conical segment, by opening the second clamping jaw 2232, the conical segment can be clamped in the subsequent step to avoid damage to the conical segment caused by the rigid contact between the second clamping jaw 2232 and the conical segment.

[0062] Step S40: drive a set of second clamping jaws 2232 to clamp on the conical surface of the outermost dust cover 40. By actively clamping the second clamping jaw 2232, the second clamping jaw 2232 can be adapted to different outer diameters of the dust cover 40 for clamping.

[0063] Step S50: drive the first clamping jaw 2222 and the second clamping jaw 2232 to carry the multiple dust covers 40 to the box 50. The previous steps have solved the problems of deformation, scratching, cracking, etc. by stable stacking, flexible clamping, and adapting to the conical surface. Step S50 carries the intact batch of dust covers 40 to the box 50, which can reduce the rate of defective products after packaging.

[0064] Further, step S30 includes step S31 and step S32.

[0065] Step S31: based on the support rod 134 being flipped to the first state, drive the compression ring 32 to extrude the dust cover 40 away from the support seat 131 to the first set position. Although the nested stacking in the previous step can achieve coaxial positioning, the elastic properties of the bellows of the dust cover 40 may cause a small axial gap between adjacent dust covers 40. Or due to the influence of the flipping of the support rod 134, the multiple stacked dust covers 40 may displace due to inertia, resulting in inconsistent gaps between the multiple dust covers 40. The compression ring 32 actively extrudes the dust cover 40 away from the support seat 131 to the first set position, which can eliminate these gaps through pressure, facilitate the positioning of the gap between the first clamping jaw 2222 and the dust cover, and facilitate the subsequent clamping of the dust cover by the first clamping jaw 2222 to improve the stability of the dust cover during carrying.

[0066] Step S32: Based on the pressing ring 32 extruding the dust cover 40 away from the support seat 131 to a first set position, drive a group of second clamping jaws 2232 to an open state and drive at least a group of first clamping jaws 2222 and a group of second clamping jaws 2232 to move towards the dust cover 40 to a first position. After extrusion by the pressing ring 32, the stacked form of the plurality of dust covers 40 is more regular, and when the first clamping jaw 2222 moves to the first position, the contact point and the force direction of the first clamping jaw 2222 can accurately match the gap between the adjacent dust covers 40.

[0067] Further, step S40 includes:

[0068] Step S41: Based on the movement of at least a group of first clamping jaws 2222 and a group of second clamping jaws 2232 towards the dust cover 40 to a first position, drive the pressing ring 32 to move away from the dust cover 40 to make the dust cover 40 move to a second set position, wherein the pressing ring 32 is in abutment with the dust cover 40 at the second set position, and the first set position is between the second set position and the support seat 131. In the case that the clamping force of the second clamping jaw 2232 is limited, if the clamping position of the second clamping jaw 2232 is biased towards the small diameter end of the dust cover 40, it may slip due to insufficient friction, resulting in unstable clamping. During the movement of the dust cover 40 to the second set position, the part with a larger outer diameter of the conical surface moves towards the second clamping jaw 2232 due to the decrease in the compression amount between the dust covers 40.

[0069] Step S42: Based on the movement of the dust cover 40 to the second set position, drive a group of second clamping jaws 2232 to clamp on the conical surface of the outermost dust cover 40. Clamping on the part with a larger outer diameter can form a larger contact area, generating a larger friction force between the dust cover 40 and the second clamping jaw 2232, and the second clamping jaw 2232 can stably clamp the conical surface of the dust cover 40. Thus, the risk of the dust cover 40 falling off during transportation is reduced.

[0070] Further, the dust cover 40 includes a first clamping ring 41, a second clamping ring 43, and a conical bellows 42; the first clamping ring 41 is coaxially connected with the small diameter end of the conical bellows 42; and the second clamping ring 43 is coaxially connected with the large diameter end of the conical bellows 42.

[0071] In step S30, the first position includes two free ends of a group of first clamping jaws 2222 located in the concave pits of the conical bellows 42. The side wall of the concave pit will abut against the first clamping jaw 2222, forming an axial restraint force on the dust cover 40, ensuring that the stacked plurality of dust covers 40 do not relatively displace during transportation.

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

[0073] Step S421: based on the dust cover 40 moving to the second set position, a set of second clamping jaws 2232 are driven to clamp on the conical surface of the outermost dust cover 40.

[0074] Step S422: based on the second clamping jaw 2232 clamping on the conical surface of the outermost dust cover 40, the compression ring 32 is driven to reciprocate along the axis direction of the support rod 134 by a set distance. If the second clamping jaw 2232 only clamps on the top of the wrinkle, it does not fall into the groove of the corrugated pipe, which may cause the clamping to be loose due to the small contact area and insufficient friction. The reciprocating movement of the compression ring 32 along the axis can drive the entire stack of dust covers 40 to move slightly in the axial direction, and the elastic deformation of the corrugated pipe can cause the contact position of the second clamping jaw 2232 and the conical surface to be adjusted slightly in the axial direction. During the reciprocating process, the clamping jaw will be clamped into the nearest groove due to the resistance of the groove, thereby avoiding the instability of the clamping caused by the second clamping jaw 2232 clamping on the top of the wrinkle.

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

[0076] Step S51: based on the second clamping jaw 2232 clamping on the conical surface of the outermost dust cover 40, the compression ring 32 is driven to be separated from the support rod 134, and the support rod 134 is driven to be extracted from the inner hole of the dust cover 40. The support rod 134 serves as the internal skeleton of the dust cover 40 stack, which achieves coaxial positioning, but if it is not extracted during packing, it may cause subsequent packing to be complex. At the same time, after the support shaft is extracted, it is convenient for the support shaft to support the dust cover 40 that needs to be stacked subsequently.

[0077] Step S52: based on the support rod 134 being extracted from the inner hole of the dust cover 40, the first clamping jaw 2222 and the second clamping jaw 2232 are driven to carry the plurality of dust covers 40 to the unloading position of the box 50. Compared with manually carrying the dust cover 40 to the box 50, it is easy to cause the dust cover 40 to be skewed due to visual error. The first clamping jaw 2222 and the second clamping jaw 2232 are driven based on the preset program, which can accurately carry the stacked unit to the unloading position, ensure that the relative position of the dust cover 40 and the box 50 meets the preset requirements, maximize the use of the space in the box, and lay a foundation for subsequent stable stacking of the box 50.

[0078] Step S53: based on the dust cover 40 being carried to the unloading position of the box 50, the second clamping jaw 2232 is driven to the unloading state, and the unloading rod 2242 drives the dust cover 40 to separate from the first clamping jaw 2222; wherein the unloading state includes that the second clamping jaw 2232 is spaced from the dust cover 40. The second clamping jaw 2232 is first kept spaced from the dust cover 40, which avoids that the dust cover 40 opens the second clamping jaw 2232 to damage the active opening and closing structure of the second clamping jaw 2232 when unloading. The whole unloading process does not need manual contact with the dust cover 40, which avoids that the oil stains and impurities of the manual hand pollute the dust cover 40, reduces the uncertainty of manual operation, and realizes the full-process automation of packaging and boxing.

[0079] Further, step S51 includes step S511 and step S512.

[0080] Step S511: based on the second clamping jaw 2232 clamping on the conical surface of the outermost dust cover 40, the pressing ring 32 is driven to be separated from the support rod 134.

[0081] Step S512: based on the pressing ring 32 being separated from the support rod 134, the first clamping jaw 2222 and the second clamping jaw 2232 are driven to lift the dust cover 40 to be spaced from the support rod 134.

[0082] If the support rod 134 is directly pulled out, the friction between the support rod 134 and the dust cover 40 may drive the dust cover 40 to move, which may damage the cooperation between the first clamping jaw 2222, the second clamping jaw 2232 and the dust cover 40. After the lifting forms the spacing, when the support rod 134 is pulled out, there is almost no resistance, which will not generate additional force on the stacked unit, ensures that the dust cover 40 remains in the compact stacked state during the whole process of pulling out the support rod 134, and avoids the scattering or mispositioning caused by external interference.

[0083] Further, in step S53:

[0084] The unloading state also includes that the minimum outer diameter of the circular ring where the two free ends of the group of second clamping jaws 2232 are located is less than the maximum outer diameter of the dust cover 40. If the two free ends of the second clamping jaw 2232 are opened and the outer diameter of the circular ring where the two free ends are located is greater than the maximum outer diameter of the dust cover 40, the outer side of the clamp is easy to directly contact and rub with the inner wall of the box 50 when unloading in the box 50, especially when the box 50 is made of paper box, plastic box or other easily damaged materials, which is easy to cause the side wall of the box 50 to be scratched or damaged. The minimum outer diameter of the circular ring where the two free ends of the second clamping jaw 2232 are located is less than the maximum outer diameter of the dust cover 40, which means that the outermost contour of the clamping jaw is always within the maximum outer diameter range of the dust cover 40 after the clamping jaw is opened, and the clamping jaw and the inner wall of the box 50 are always separated by the dust cover 40 when unloading, so they will not directly contact, which avoids the risk that the clamping jaw scratches the box 50, and guarantees the structural integrity of the box 50.

[0085] Further, in step S20:

[0086] The first state also includes that one end of the support rod 134 connected to the support base 131 is inclined downward relative to the other end. In this way, the dust cover 40 naturally approaches the support base 131 along the inclined direction, forming a self-pressing effect, which can prevent the dust cover 40 from being dispersed due to its own weight sliding outward along the support rod 134, thereby facilitating subsequent clamping of the plurality of dust covers 40 by the first clamping jaw 2222 and the second clamping jaw 2232.

[0087] Embodiment two:

[0088] The embodiment provides a dust cover packaging system; the dust cover packaging system is applied to any dust cover packaging method in embodiment one. As shown in Figure 2 The dust cover packaging system includes a frame assembly 60, a box body 50, a turnover assembly 10, and a grabbing unit 22. The box body 50 is arranged on the frame assembly 60; the box body 50 has a containing space and an upward opening; the opening is in communication with the containing space. The upward opening is designed to provide an unobstructed channel for the unloading operation of the grabbing unit 22, avoid unloading interference caused by a side opening, and improve the efficiency of the unloading operation.

[0089] The turnover assembly 10 includes a turnover base 11, a turnover unit 12, and a support unit 13, wherein the support unit 13 includes a support base 131 and a support rod 134; the support base 131 is connected to one end of the support rod 134; the turnover base 11 is connected to the frame assembly 60; the turnover unit 12 is rotationally connected to the turnover base 11; and the support base 131 is drivingly connected to the turnover unit 12. The support rod 134 is adapted to the hollow structure of the dust cover 40, so that the plurality of dust covers 40 can be coaxially nested, which can avoid tilting and mispositioning caused by manual stacking. As shown in Figure 2 and Figure 3 The turnover unit 12 is rotationally connected to the turnover base 11, and the turnover unit 12 can drive the support rod 134 to turn to the first state.

[0090] As shown in Figure 5 and Figure 6 The grabbing unit 22 includes a grabbing base 221, a first clamping module 222, and a second clamping module 223; the grabbing base 221 is movably connected to the frame assembly 60; the first clamping module 222 includes a plurality of first clamping bases 2221 and a plurality of groups of first clamping jaws 2222; and the second clamping module 223 includes a first driving part 2233, at least one second clamping base 2231, and at least one group of second clamping jaws 2232.

[0091] The first clamping seat 2221 is connected with the grabbing seat 221; a plurality of first clamping seats 2221 are arranged in sequence and at intervals; and the movable end of each group of first clamping claws 2222 is connected with a first clamping seat 2221 in one-to-one correspondence. The plurality of first clamping seats 2221 are arranged at intervals along the grabbing seat 221, and the plurality of groups of first clamping claws 2222 are connected in one-to-one correspondence, so that the stacked dust covers 40 can be formed to be half-enclosed at multiple points, the clamping force can be dispersed, and local stress concentration that causes crease damage to the bellows can be avoided.

[0092] The second clamping seat 2231 and the first driving part 2233 are respectively connected with the grabbing seat 221; the second clamping claw 2232 is movably connected with the second clamping seat 2231, and the second clamping claw 2232 is drivingly connected with the first driving part 2233; the first driving part 2233 comprises a driving state; the driving state comprises that the first driving part 2233 drives the second clamping claw 2232 to open or clamp. The first driving part 2233 is drivingly connected with the second clamping claw 2232, so that the clamping force can be accurately controlled, and the clamping can be adapted to the taper of the dust cover 40. Meanwhile, the automatic control of the driving part replaces manual adjustment, and the working efficiency can be improved. Then, the first clamping claw 2222 and the second clamping claw 2232 can carry the plurality of dust covers 40 to the box body 50, completely solve the problems of deformation, scratching, cracking and the like through stable stacking, flexible clamping and adaptation to the taper, and carry the intact batch of dust covers 40 to the box body 50, so that the defective product rate after packaging can be significantly reduced.

[0093] In some other embodiments, as shown in Figure 4 The overturning unit 12 comprises a second driving part 121 and an overturning part 122; the overturning part 122 is rotationally connected with the overturning base 11; the overturning part 122 is drivingly connected with the second driving part 121; and the support seat 131 is connected with the overturning part 122. If the overturning structure relies on manual overturning or is unpowered, the inclination angle of the dust cover 40 will have random errors due to the operation force, equipment wear and the like, so that the subsequent clamping claw is difficult to align. The second driving part 121 can set an accurate overturning angle through a program, so as to ensure that the dust cover 40 is in a preset inclined posture with the end of the support seat 131 downward after overturning.

[0094] In some other embodiments, as shown in Figure 4 The support unit 13 further comprises a sliding part 132 and a third driving part 133. The sliding part 132 is movably connected with the overturning part 122; the sliding part 132 is drivingly connected with the third driving part 133; and the support seat 131 is connected with the sliding part 132. The movable connection between the sliding part 132 and the overturning part 122 can constrain the extraction path of the support rod 134, so as to ensure that the motion trajectory is strictly coincided with the inner hole axis of the dust cover 40.

[0095] In some other embodiments, as shown in Figure 2 and Figure 3As shown, the dust cover packaging system further comprises a carrying assembly 20; the carrying assembly 20 comprises a moving unit 21 and a grabbing unit 22; the moving unit 21 comprises 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 with the frame assembly 60 along the x-axis direction; the second translation module 212 is movably connected with the first translation module 211 along the y-axis; the vertical translation module 213 is connected with the second translation module 212 along the z-axis; the rotation module 214 is rotationally connected with the vertical translation module 213; and the grabbing seat 221 is connected with the rotation module 214. The four-dimensional movement of the x-axis, y-axis, z-axis and rotation of the moving unit 21 enables the grabbing unit 22 to cover all key workstations on the frame, without manual movement of the box 50 or adjustment of the frame, and enables automatic packing.

[0096] In some embodiments, the first clamping module 222 comprises a resilient portion 2223; the free end of the first clamping jaw 2222 is connected with the resilient portion 2223; the resilient portion 2223 has elastic deformation for driving the first clamping jaw 2222 to a reset position; the reset position comprises that the distance between the two free ends of the first clamping jaw 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. In this way, the first clamping jaw 2222 can be elastically deformed when contacting the dust cover 40, thereby semi-enclosing the dust cover 40, and then the free end of the first clamping jaw 2222 is in abutment with the dust cover 40 through the elastic reset capability of the resilient portion 2223, thereby clamping the dust cover 40.

[0097] In some embodiments, as shown in Figure 5 and Figure 6 the grabbing unit 22 comprises an unloading module 224; the unloading module 224 comprises a fourth driving portion 2241 and an unloading rod 2242; the fourth driving portion 2241 is connected with the grabbing seat 221; the unloading rod 2242 is movably connected with the fourth driving portion 2241; and the fourth driving portion 2241 is used for driving the unloading rod 2242 to extrude the dust cover 40 out of the clamping space of the first clamping jaw 2222 and the clamping space of the second clamping jaw 2232. After the second clamping jaw 2232 is moved to the unloading state, the first clamping jaw 2222 clamps the dust cover 40 through the friction force and the elastic force of the resilient portion 2223, and then the dust cover 40 is extruded by the unloading rod 2242 to overcome the friction force between the first clamping jaw 2222 and the dust cover 40 and the elastic force of the resilient portion 2223, so as to push the dust cover 40 to fall into the box 50, thereby completing the packaging and transfer of the box.

[0098] In some embodiments, as shown in Figure 2 and Figure 3As shown, the dust cover packaging system further comprises a pressing assembly 30, the pressing assembly 30 comprising a fifth driving part 31, a pressing ring 32; the fifth driving part 31 is connected with the frame assembly 60; the pressing ring 32 is drivingly connected with the fifth driving part 31.

[0099] In some other embodiments, as Figure 7 As shown, the dust cover 40 comprises a first clamping ring 41, a second clamping ring 43, a conical bellows 42; the first clamping ring 41 is coaxially connected with the small-diameter end of the conical bellows 42; the second clamping ring 43 is coaxially connected with the large-diameter end of the conical bellows 42.

[0100] Those skilled in the art can understand that the above-mentioned embodiments are specific cases for realizing the present disclosure, and in actual application, various changes can be made in form and details without departing from the scope of the present disclosure.
