Description

Technical Field

[0001] This invention relates to the field of tooling and fixtures, and more specifically to an automatic pipe bending system. Background Technology

[0002] Pipe fittings are widely used in many industries. Whether it is automobiles, ships, airplanes, or equipment, straight or curved pipe fittings are inevitably used. Curved pipe fittings are made using automatic pipe bending devices.

[0003] In related technologies, for automatic pipe bending devices, the feeding device in the automatic pipe bending device can only store pipes with one or two cross sections, and at the same time, the positioning effect of stacked pipes is poor. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic pipe bending system that automatically compresses spring plates, reducing the labor intensity of operators, improving assembly efficiency, and ensuring good assembly results.

[0005] An automatic pipe bending system according to an embodiment of the present invention includes: a pipe bending device, a feeding device, and a robot. The pipe bending device is used to clamp and bend a pipe. The feeding device is disposed adjacent to the pipe bending device and includes at least one set of pipe rack assemblies for placing the pipe to be bent. The robot is disposed adjacent to the pipe bending device and the feeding device and is used to feed the pipe from the pipe rack assembly to the pipe bending device. The pipe rack assembly includes: an upper plate and a lower plate. The upper plate has a first support column and a through groove. The lower plate is located below the upper plate and has a second support column passing through the through groove. A clamping groove for holding the pipe is defined between the first and second support columns. The through groove is larger than the second support column in a first direction, and the upper plate is translatable relative to the lower plate in the first direction.

[0006] The automatic pipe bending system of this invention allows for adjustment of the distance between the first and second support columns, enabling the slots to hold pipes of different specifications; ensuring that stacked pipes are aligned with each other and that adjacent pipes do not misalign, thus enabling the automatic pipe bending system to quickly position pipes of various cross-sections.

[0007] In some embodiments, the first support columns on the upper plate are arranged in multiple rows and columns, and the through slots are correspondingly arranged on one side of the first support columns. The lower plate is correspondingly provided with multiple rows and columns of second support columns. This arrangement, on the one hand, can increase the number of tube storage positions, which is beneficial to improving the storage capacity of the feeding device; on the other hand, it can meet the storage of long tubes, so that the tube bending device system can adapt to the bending of long tubes.

[0008] In some embodiments, a handle is provided at least at one end of the upper plate in a first direction to facilitate translation of the upper plate. This configuration is economical and reduces production costs.

[0009] In some embodiments, the feeding device is equipped with two sets of tube rack assemblies for holding two types of tubes, and the robot alternately places the two types of tubes onto the tube bending device. This arrangement can reduce the robot's waiting time and optimize the tube bending device system.

[0010] In some embodiments, the pipe bending device is provided with a clamping assembly, which includes a base, a first clamping member, and a second clamping member. Both the first clamping member and the second clamping member are mounted on the base and are arranged at a preset angle. This configuration allows the clamping assembly to clamp two different types of pipes, thus broadening the application range of the pipe bending system.

[0011] Furthermore, the first clamping element includes two first jaws, at least one of which is horizontally movable to clamp a tube. This configuration allows the tube to be clamped from two directions, preventing accidental collisions with the tube during clamping and improving the stability of the clamped tube.

[0012] Furthermore, the clamping assembly also includes a suction cup disposed between the two first grippers, wherein the suction cup is at least one of a magnetic suction cup or a negative pressure suction cup. This arrangement, on the one hand, allows the tube to be placed in the first upper clamping space or the first lower clamping space by adsorption; on the other hand, it adds another side to clamp the tube, improving the stability of the first clamping member clamping the tube.

[0013] Furthermore, the second clamping element includes two second jaws, at least one of which is vertically movable to clamp another tube. This configuration allows the tube to be clamped from two directions, preventing accidental collisions with the tube during clamping and improving the stability of the clamped tube.

[0014] In some embodiments, the automated pipe bending system further includes a fence that encloses a work area, within which the pipe bending device, feeding device, and robotic arm are located. The fence comprises multiple modular panels. This design prevents unauthorized personnel from accidentally entering the pipe bending area and being injured.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The following is for reference. Figures 1-7 An automatic pipe bending system 100 according to an embodiment of the present invention is described.

[0046] like Figures 1-4 As shown, Figure 1 A schematic diagram of an automatic pipe bending system according to an embodiment of the present invention is shown; Figure 2 A schematic diagram of the feeding device according to an embodiment of the present invention is shown; Figure 3 A schematic diagram of the structure of the tube rack assembly according to an embodiment of the present invention is shown; Figure 4 An exploded view of the pipe rack assembly according to an embodiment of the present invention is shown. Wherein, Figure 4 Establish an X, Y, and Z coordinate system, with X, Y, and Z axes perpendicular to each other.

[0047] An automatic pipe bending system 100 according to an embodiment of the present invention includes: a pipe bending device 10, a feeding device 20, a robotic arm 30, and a material placement table 40. The pipe bending device 10 is used to clamp and bend pipe bodies 50; the feeding device 20 is disposed adjacent to the pipe bending device 10, and the feeding device 20 includes at least one set of pipe support assemblies 21, which are used to place the pipe bodies 50 to be bent; the robotic arm 30 is disposed adjacent to the pipe bending device 10 and the feeding device 20, and is used to deliver the pipe bodies 50 on the pipe support assemblies 21 to the pipe bending device 10; wherein, the pipe support assembly 21 includes: an upper plate 211 and a lower plate 212, the upper plate 211... The upper plate 211 is provided with a first support column 2112 and a through groove 2111. The lower plate 212 is located below the upper plate 211. The lower plate 212 is provided with a second support column 2121 passing through the through groove 2111. A slot for holding the tube 50 is defined between the first support column 2112 and the second support column 2121. The through groove 2111 is larger than the second support column 2121 in the first direction, and the upper plate 211 can be translated relative to the lower plate 212 in the first direction.

[0048] In other words, in the pipe bending device 10 system of this embodiment, the feeding device 20 stores and provides the pipe body 50, the robot arm 30 grabs and transfers the pipe body 50, the pipe bending device 10 clamps the pipe body 50 and bends it, and the material placement table 40 places the bent pipe body 50.

[0049] like Figure 7 As shown, the robotic arm 30 here is multi-degree-of-freedom, capable of mimicking certain movements of a human hand and arm to grasp and transport the tube 50 according to a fixed program. It should be noted that this embodiment does not impose specific limitations on the structure of the robotic arm 30.

[0050] like Figure 5 As shown, the pipe bending device 10 includes a pushing component 13, a bending component 12, and a clamping component 11. The pushing component 13 pushes the area to be bent of the pipe body 50 to the clamping component 11; the clamping component 11 clamps the area to be bent of the pipe body 50; and the bending component 12 bends the area to be bent into a preset state. The bending component 12 includes a rotating component 121 and a cylindrical mold 122. The cylindrical mold 122 abuts against the pipe body 50, and the rotating component 121 rotates relative to the cylindrical mold 122. The clamping component 11 is connected to the rotating component 121. The area to be bent of the pipe body 50 abuts against the cylindrical mold 122, and the rotating component 121 drives the clamping component 11 to rotate, causing the area to be bent to be bent and deformed by the curved surface of the cylindrical mold 122. It should be noted that this embodiment does not impose specific limitations on the structure of the pushing component 13 and the bending component 12.

[0051] The feeding device 20 includes at least one set of pipe rack assemblies 21, which include an upper plate 211 and a lower plate 212, the upper plate 211 and the lower plate 212 being disposed opposite to each other, with the lower plate 212 located below the upper plate 211. The upper plate 211 is provided with a first support column 2112 and a through groove 2111, the through groove 2111 being formed on the surface of the upper plate 211, the through groove 2111 being continuous and extending along a first direction. The first support column 2112 is formed by extending along a second direction on the surface of the upper plate 211, or the through groove 2111 extending from its inner sidewall along the second direction to form the first support column 2112. The second direction is perpendicular to the first direction, and the first direction and the second direction are not coplanar. Figure 4 As shown, the first direction is the X direction, and the second direction is the Z direction.

[0052] A second support post 2121 extends along a second direction on the surface of the lower plate 212. The second support post 2121 passes through a through groove 2111, and a retaining groove for holding the tube body 50 is defined between the second support post 2121 and the first support post 2112. The size of the second support post 2121 is smaller than the size of the through groove 2111 in the first direction. Here, "size of the second support post 2121" refers to the diameter of the second support post 2121 or the size of the second support post 2121 in the first direction. For example, the second support post 2121 is cylindrical, and its size is its diameter; for example, the second support post 2121 is stepped, and the surface of the second support post 2121 is perpendicular to the first direction, and its size is its thickness.

[0053] The upper plate 211 is movable relative to the lower plate 212 along a first direction. This can be understood as the lower plate 212 remaining stationary while the upper plate 211 moves along the first direction. The second support column 2121 slides into the slot 2111, allowing the distance between the second support column 2121 and the first support column 2112 to be adjusted. Therefore, the slot can hold tubes 50 of different specifications. Alternatively, the upper plate 211 remains stationary while the lower plate 212 moves along the first direction. The second support column 2121 slides into the slot 2111, allowing the distance between the second support column 2121 and the first support column 2112 to be adjusted. Thus, the slot can hold tubes 50 of different specifications. Here, "specifications" refers to the cross-sectional size of the tube 50, which is perpendicular to the extension direction of the tube 50.

[0054] In this embodiment, the distance between the first support column 2112 and the second support column 2121 can be adjusted, so that the slot can hold tubes 50 of different specifications; ensuring that the stacked tubes 50 are aligned with each other and that there is no misalignment between adjacent tubes, so the automatic tube bending system 100 can adapt to the rapid positioning of tubes 50 with various cross-sections.

[0055] like Figure 4As shown, in some embodiments, a first support post 2112 is formed extending along a second direction on the surface of the upper plate 211, and the first support post 2112 is located at the end of the through groove 2111. This arrangement can prevent the first support post 2112 from occupying the internal space of the through groove 2111, increase the movement space of the second support post 2121 in the through groove 2111, and thus facilitate the holding of large-diameter pipes 50.

[0056] like Figure 4 As shown, in some embodiments, the cross-sections of the first support column 2112 and the second support column 2121 are circular. This arrangement ensures that the first support column 2112 and the tube body 50 are in line contact, and the second support column 2121 and the tube body 50 are in line contact, thereby reducing the frictional resistance of the first and second support columns to the tube body 50, which in turn facilitates the gripper 30 in holding the tube body 50.

[0057] In some embodiments, the second support post 2121 is guided and engaged with the through slot 2111.

[0058] like Figure 3 As shown, it should be noted that the slot 2111 guides the second support column 2121, allowing the second support column 2121 to move along the first direction while restricting its movement in the third direction. Figure 4 As shown, the third direction is the Y direction, which is perpendicular to the first direction and lies in the same plane. The maximum dimension of the cross-section of the part corresponding to the second support column 2121 and the through groove 2111 can be slightly smaller than the width of the through groove 2111. This setting can avoid misalignment between the stacked tubes 50 due to the shaking of the second support column 2121, and is conducive to the robot arm 30 accurately grasping the preset clamping position on the tube 50.

[0059] like Figure 4 As shown, in some embodiments, at least one end of the upper plate 211 in the first direction is provided with a handle 2113 to translate the upper plate 211. The upper plate 211 is driven by a non-powered motor, which is economical and reduces production costs.

[0060] In some embodiments, the first support columns 2112 on the upper plate 211 are arranged in multiple rows and columns, and the through slots 2111 are correspondingly arranged on one side of the first support columns 2112. The lower plate 212 is correspondingly provided with multiple rows and columns of second support columns 2121.

[0061] In a specific embodiment, the surface of the upper plate 211 is provided with N rows and M columns of first support posts 2112 and N rows and M columns of recessed slots 2111, with one slot 2111 corresponding to one first support post 2112; the surface of the lower plate 212 is provided with N rows and M columns of second support posts 2121, with the second support posts 2121 passing through the slots 2111, and one second support post 2121 corresponding to one slot 2111. Figure 3 As shown, N is 3 and M is 3.

[0062] Setting up N rows of first support columns 2112 and second support columns 2121 can increase the storage space of the tube body 50, which is beneficial to improving the storage capacity of the feeding device 20; setting up M columns of first support columns 2112 and second support columns 2121 can meet the storage of long tube bodies 50, so that the tube bending device 10 system can adapt to the bending of long tube bodies 50.

[0063] like Figure 2 As shown, in some embodiments, the feeding device 20 is equipped with two sets of tube rack assemblies 21 for placing two types of tubes 50, and the robot arm 30 alternately places the two types of tubes 50 onto the tube bending device 10. This arrangement can reduce the waiting time of the robot arm 30 and optimize the tube bending device 10 system.

[0064] Furthermore, such as Figure 2 As shown, the feeding device 20 also includes a support platform 22 for supporting the tube rack assembly 21, and the support platform 22 is slidably engaged with the tube rack assembly 21. That is, one of the support platform 22 and the tube rack assembly 21 is provided with a track 23, and the other is provided with a pulley (not shown) that cooperates with the track 23. When the robot arm 30 grasps a tube body 50, the tube rack assembly 21 storing the one type of tube body 50 is close to the robot arm 30, while the tube rack assembly 21 storing the other type of tube body 50 is far away from the robot arm 30, so as to avoid interference of the tube rack assembly 21 storing the other type of tube body 50 with the movement of the robot arm 30.

[0065] Furthermore, such as Figure 2 As shown, the bottom of the feeding device 20 is equipped with rollers 24, which can facilitate the movement of the feeding device 20.

[0066] In some embodiments, the pipe bending device 10 is provided with a clamping assembly 11, which includes a base 113, a first clamping member 111 and a second clamping member 112. The first clamping member 111 and the second clamping member 112 are both mounted on the base 113, and the first clamping member 111 and the second clamping member 112 are arranged at a preset angle.

[0067] It should be noted that, as Figure 6As shown, a two-dimensional coordinate system is established on the base 113, with the X and Y axes perpendicular to each other. If the first clamping member 111 is positioned along the positive X-axis, the second clamping member 112 can be positioned along the positive Y-axis, or the second clamping member 112 can be positioned along the negative X-axis, or the second clamping member 112 can be positioned between the positive and negative X-axis. The first clamping member 111 can clamp one type of pipe 50, and the second clamping member 112 can clamp another type of pipe 50. By rotating the base 113, the system can switch between the first clamping member 111 and the second clamping member 112, thereby enabling the switching between the two types of pipe 50. This configuration allows the clamping assembly 11 to clamp two different types of pipe 50, broadening the application scenarios of the pipe bending system. Here, "type" refers to the shape of the pipe 50, which can be a round pipe, a square pipe, or a thin plate, etc.

[0068] Furthermore, the preset included angle is 90°, that is, the first clamping member 111 is set along the X direction and the second clamping member 112 is set along the Y direction.

[0069] Furthermore, the first clamping member 111 includes two first grippers 1111, at least one of which is horizontally movable to clamp a tube 50. This configuration allows the tube 50 to be clamped from two directions, preventing accidental collisions with the tube 50 during clamping and facilitating stable clamping of the tube 50.

[0070] Specifically, such as Figure 6 As shown, the first clamping member 111 includes a first support plate 1112, two relatively movable first jaws 1111, and a first connecting plate 1113 connecting the first support plate 1112 and the first jaws 1111. The first support plate 1112 and the first jaws 1111 are slidably engaged through the first connecting plate 1113, so that both first jaws 1111 can move relative to the first support plate 1112. The first connecting plate 1113 and the first support plate 1112 can be configured as a ball screw or a rack and pinion mechanism. For example, if the first connecting plate 1113 and the first support plate 1112 are configured as a ball screw, the screw is mounted on the first support plate 1112. One half of the screw has a right-hand thread, a nut engages with the right-hand thread, and a first connecting plate 1113 is connected to the nut. The other half of the screw has a left-hand thread, another nut engages with the left-hand thread, and another first connecting plate 1113 is connected to the other nut. When the lead screw rotates forward, the two first connecting plates 1113 move toward each other, and the two first grippers 1111 clamp the tube body 50; when the lead screw rotates in reverse, the two first connecting plates 1113 move away from each other, and the two first grippers 1111 release the tube body 50.

[0071] In some proposals, Figure 6In the first clamping member 111, one of the first jaws 1111 moves while the other first jaw 1111 remains stationary. One first connecting plate 1113 and one first support plate 1112 are connected by a ball screw; the other first connecting plate 1113 and the other first support plate 1112 are both fixedly installed.

[0072] Furthermore, the first gripper 1111 is stepped, and the first gripper 1111 forms a first upper gripping portion 1111a and a first lower gripping portion 1111b along the X direction.

[0073] Specifically, such as Figure 6 As shown, the first clamping member 111 is wider at the top and narrower at the bottom. It includes two first clamping claws 1111, which are stepped. The first clamping claws 1111 form a first upper clamping portion 1111a and a first lower clamping portion 1111b along the X direction. The two first upper clamping portions 1111a form a first upper clamping space, and the two first lower clamping portions 1111b form a first lower clamping space. The first lower clamping space is different from the first upper clamping space. The first upper and lower clamping spaces can clamp tubes 50 of different specifications. This configuration allows the first clamping member 111 to clamp two specifications of tubes 50, thus broadening the application range of the first clamping member 111.

[0074] In addition, such as Figure 6 As shown, the clamping assembly 11 also includes a suction cup 114 disposed between the two first clamping jaws 1111. The suction cup 114 is at least one of a magnetic suction cup 114 or a negative pressure suction cup 114. The suction cup 114 reciprocates along the extending direction (X direction) of the first clamping jaws 1111. This arrangement, on the one hand, places the tube body 50 in the first upper clamping space or the first lower clamping space by adsorption; on the other hand, it increases the clamping surface of the tube body 50, improving the stability of the first clamping member 111 clamping the tube body 50.

[0075] Furthermore, such as Figure 6 As shown, the second clamping member 112 includes two second grippers 1121, at least one of which is vertically movable to clamp another tube 50. This configuration allows the tube 50 to be clamped from two directions, avoiding accidental collisions with the tube 50 during clamping and facilitating stable clamping of the tube 50.

[0076] It should be noted that the second clamping member 112 includes two second clamping jaws 1121, two second support plates 1122, and two second connecting plates 1123. The structure of the second clamping member 112 is the same as that of the first clamping member 111, and its specific structure can be referred to the first clamping member 111 described above, so it will not be repeated here. Both clamping jaws 1121 can move relative to the second support plates 1122, and their connection structure is as described above, so it will not be repeated here.

[0077] Furthermore, the structure of the second gripper 1121 can be the same as that of the first gripper 1111. The second gripper 1121 is stepped, and its specific structure is the same as that of the first gripper 1111 described above, so it will not be repeated here.

[0078] In addition, the second clamping member 112 may also include the aforementioned suction cup 114, which is located between the two second grippers 1121.

[0079] In some embodiments, the pipe bending device 10 system further includes a fence that encloses a work area. The pipe bending device 10, the feeding device 20, the robot arm 30, and the material placement platform 40 are located within the work area. The fence includes multiple modular panels. This arrangement prevents unauthorized personnel from accidentally entering the pipe bending area and being injured.

[0080] In the description of this specification, references to terms such as "embodiment," "example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0081] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
