Description

Technical Field

[0001] The present invention belongs to the technical field of busbar processing, and particularly relates to an automated terminal bending system. Background Art

[0002] A busbar, also known as a bus or a busbar trunking, is a key component for transmitting electric energy in a power system. It is usually made of a metal with good electrical conductivity and has a relatively large cross-sectional area to be able to carry a large current without generating excessive heat. Among them, during the processing of the busbar, a bending device is required for bending.

[0003] Currently, the bending process of busbars mainly relies on various types of bending devices, such as hydraulic busbar bending machines, mechanical busbar bending machines, and numerical control bending machines. These devices achieve precise bending of busbars through different power sources and control methods. However, in the existing bending process, it is usually necessary for workers to manually place the busbar to be bent on the bending mechanism, and the bending mechanism directly contacts the busbar for processing. This processing method has some obvious deficiencies: on the one hand, the intervention of workers not only increases the labor cost and the complexity of operation, but also may lead to unstable processing accuracy; on the other hand, the direct contact between the bending mechanism and the busbar is likely to cause scratches on the surface of the busbar, which not only affects the appearance quality of the product, but also may have a potential impact on the electrical performance of the busbar, reducing the overall performance and reliability of the product. Summary of the Invention

The second guiding roller flips the protective belt guided by the first guiding roller by 180 degrees, changes the transmission direction of the protective belt, makes the protective belt pass through between the bending upper die assembly and the bending lower die again, and transmits it in the direction of the receiving roller, and the protective belt is laid on the bending lower die to realize the protection of the bending lower die.

[0006] Further, the tray includes a tray body, a receiving groove disposed on the tray body, and a tray opening disposed on one side of the receiving groove.

[0007] Further, a fillet is provided at the connection position between the first guiding groove and the second guiding groove.

Thus, when the connecting plate rotates, it drives the rotating shaft to rotate, and synchronously drives the tray to rotate. A pulley is arranged at the free end of the connecting shaft, and the pulley is accommodated in the guiding groove. Thus, when the pulley slides along the guiding groove, the pulley drives the connecting shaft to rotate along with the guiding groove. Among them, the guiding groove includes a first guiding groove and a second guiding groove arranged at one end of the first guiding groove away from the bending mechanism. The extending directions of the first guiding groove and the second guiding groove are perpendicular to each other. When the transmission mechanism transports the to-be-bent busbar to the bending mechanism, the pulley is accommodated in the second guiding groove, with the tray opening of the tray facing outward. The to-be-bent busbar is clamped and installed in the accommodating groove by a manipulator. The sliding assembly drives the tray assembly to slide towards the bending mechanism, and the pulley slides in the first guiding groove. Since the extending directions of the first guiding groove and the second guiding groove are perpendicular to each other, the connecting shaft rotates synchronously by 90 degrees, driving the tray opening of the tray to face the bending mechanism, thus facilitating the transfer of the to-be-bent busbar on the tray to the bending mechanism. The bending mechanism includes a bending lower die arranged on the workbench and a bending upper die assembly arranged on one side of the bending lower die. The feeding mechanism in the bending protection mechanism is used to transport the protective belt, the receiving mechanism is used to recycle the protective belt, and a guiding mechanism is arranged between the feeding mechanism and the receiving mechanism. Among them, the guiding mechanism includes at least one first guiding roller arranged on one side of the bending mechanism close to the transmission mechanism and at least one second guiding roller arranged on one side of the bending mechanism close to the anti-collision mechanism. The first guiding roller guides the protective belt sent out by the feeding mechanism to one side of the second guiding roller and makes the protective belt cover the upper die, thus realizing the protection of the upper die. The second guiding roller flips the protective belt guided by the first guiding roller by 180 degrees, changes the transmission direction of the protective belt, makes the protective belt pass through between the bending upper die assembly and the bending lower die again, and transports it towards the receiving roller direction, and the protective belt covers the bending lower die, realizing the protection of the bending lower die. It can be seen from this that the automated terminal bending system realizes the automatic feeding and processing of the to-be-bent busbar, ensures the product quality, and improves the product reliability.

[0023] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0024] As Figures 1 to 7 shown, it is a schematic structural diagram of the automated terminal bending system provided by the present invention. The automated terminal bending system includes a workbench 1, a transmission mechanism 10 disposed on the workbench 1 and used for transmitting the busbars to be bent, a bending mechanism 20 disposed on one side of the transmission mechanism 10, a bending protection mechanism 30 disposed on one side of the bending mechanism 20, and a collision prevention mechanism 40 disposed on the side of the bending mechanism 20 facing away from the transmission mechanism 10. The automated terminal bending system further includes some other functional modules, such as an assembly component, an electrical connection component, and a protection belt 2, etc., which should be well-known technologies to those skilled in the art and will not be elaborated in detail herein one by one.

[0025] The transmission mechanism 10 includes a transmission rack 11 disposed on the workbench 1, a guide rail 12 disposed on the transmission rack 11, a sliding assembly 13 disposed on the guide rail 11, and a tray assembly 14 disposed on the sliding device 12 and used for loading the busbar to be bent (not shown in the figure).

[0026] The transmission rack 11 is used to support the guide rail 12, the sliding assembly 13, and the tray assembly 14, and form an integral body of the guide rail 12, the sliding assembly 13, and the tray assembly 14. The transmission rack 11 is a prior art and will not be elaborated herein.

[0027] The guide rail 12 is used to guide the translation of the sliding assembly 13. One end of the guide rail 12 corresponds to the bending mechanism 20. Thus, when the sliding assembly 13 slides along the guide rail 12, the sliding assembly 13 can drive the tray assembly 14 to move to one side of the bending mechanism 20. The guide rail 12 is a prior art and will not be elaborated herein.

[0028] The sliding assembly 13 includes a sliding seat 131 slidably connected to the guide rail 12, and at least one driving device 132 disposed on the transmission rack 11 and connected to the sliding seat 131.

[0029] The driving device 132 is used to drive the sliding seat 131 to slide along the guide rail 12, so as to realize the reciprocating movement of the sliding seat 131 on the guide rail 12. In this embodiment, the driving device 132 is a belt transmission device, which is composed of a motor and a belt. The sliding seat 131 is fixedly connected to the belt. When the motor drives the belt to reciprocate, the sliding seat 131 moves synchronously. The driving device 132 is a prior art and will not be elaborated herein.

[0030] The tray assembly 14 includes a rotating shaft 141 rotatably connected to the sliding seat 131, a tray 142 fixedly connected to one end of the rotating shaft 141, a connecting plate 143 fixedly connected to the end of the rotating shaft 141 facing away from the tray 142, a connecting shaft 144 disposed on the connecting plate 143, a pulley 145 disposed on the connecting shaft 144, and a guiding groove 146 disposed on the transmission rack 11.

[0031] Both ends of the rotating shaft 141 are fixedly connected to the tray 142 and the connecting plate 143 respectively. Thus, when the connecting plate 143 rotates, it drives the rotating shaft 141 to rotate, and synchronously drives the tray 142 to rotate.

[0032] The tray 142 includes a tray body 1421, a receiving groove 1422 provided on the tray body 1421, and a tray opening 1423 provided on one side of the receiving groove 1422.

[0033] The connecting plate 143 is used to connect the rotating shaft 141 and the connecting shaft 144 together. The connecting plate 143 is fixedly connected to the rotating shaft 141 and the connecting shaft 144 respectively. When the connecting shaft 144 moves, the connecting shaft 144 drives the rotating shaft 141 to rotate through the connecting plate 143.

[0034] The pulley 145 is provided at the free end of the connecting shaft 144, and the pulley 145 is received in the guiding groove 146. When the pulley 145 slides along the guiding groove 146, the pulley drives the connecting shaft 144 to rotate following the guiding groove 146.

[0035] The guiding groove 146 includes a first guiding groove 1461 and a second guiding groove 1462 provided at one end of the first guiding groove 1461 away from the bending mechanism 20. The extending directions of the first guiding groove 1461 and the second guiding groove 1462 are perpendicular to each other, that is, the outer contour of the guiding groove 146 is in an "L" shape. A fillet is provided at the connecting position of the first guiding groove 1461 and the second guiding groove 1462 to make the sliding of the pulley 145 smooth when it slides along the guiding groove 146. One end of the first guiding groove 1461 faces the bending mechanism 20, and the other end of the first guiding groove 1461 is connected to the second guiding groove 1462. When the pulley 145 is received in the first guiding groove 1461, the tray opening 1423 of the tray 142 faces the bending mechanism 20, so as to facilitate the transmission of the busbar to be bent on the tray 142 to the bending mechanism 20. When the pulley 145 slides into the second guiding groove 1462, since the extending directions of the first guiding groove 1461 and the second guiding groove 1462 are perpendicular to each other, the connecting shaft 144 rotates synchronously by 90 degrees, that is, the tray opening 1423 of the tray 142 also rotates by 90 degrees, so as to facilitate the loading or unloading of the tray 142.

[0036] When the transfer mechanism 10 transfers the busbar to be bent to the bending mechanism 20, the pulley 145 is received in the second guiding groove 1462, with the tray opening 1423 of the tray 142 facing outward. The busbar to be bent is clamped and installed in the accommodating groove 1422 by a manipulator (not shown in the figure). The sliding assembly 13 drives the tray assembly 14 to slide towards the bending mechanism 20, and the pulley 145 slides in the first guiding groove 1461. Since the extending directions of the first guiding groove 1461 and the second guiding groove 1462 are perpendicular to each other, the connecting shaft 144 rotates synchronously by 90 degrees, driving the tray opening 1423 of the tray 142 to face the bending mechanism 20, thus facilitating the transfer of the busbar to be bent on the tray 142 to the bending mechanism 20.

[0037] The bending mechanism 20 includes a bending lower die 21 disposed on the workbench 1 and a bending upper die assembly 22 disposed on one side of the bending lower die 21.

[0038] The bending lower die 21 includes a lower die main body 211 fixedly connected to the workbench 1, a bending protrusion 212 disposed on the lower die main body 211, a lower die mounting plane 213 disposed on one side of the bending protrusion 212, two lower die limit members 214 symmetrically disposed on the lower die mounting plane 213, and a positioning hole 215 disposed at the free end of the lower die limit member 214.

[0039] The bending protrusion 212 is disposed at the free end of the lower die main body 211 and cooperates with the bending upper die assembly 22 to process the busbar to be bent. In addition, the lower die mounting plane 213 is horizontally disposed to facilitate the installation of the lower die limit members 214. The lower die limit members 214 and the positioning hole 215 are both used to limit the position of the upper die 222 during the downward pressing and bending process. Therefore, the bending protrusion 212 and the lower die limit members 214 will cooperate with the bending upper die assembly 22.

[0040] The bending upper die assembly 22 includes a lifting drive device 221 and an upper die 222 disposed on the lifting drive device 221. The lifting drive device 221 is disposed on a mounting frame, so that the upper die 222 is disposed above the bending lower die 21, and the upper die 222 corresponds to the bending lower die 21.

[0041] The driving end of the lifting drive device 221 is connected to the upper die 222 to realize the lifting of the upper die 222. In this embodiment, the lifting drive device 221 is a driving cylinder, and the lifting drive device 221 is a prior art and will not be elaborated here.

[0042] The upper die 222 includes an upper die body 2221 fixedly connected to the lifting drive device 221, a bending groove 2222 provided on one side of the upper die body 221, an upper die mounting plane 2223 provided on one side of the bending groove 2222, and two upper die limit members 2224 provided on the upper die mounting plane 223.

[0043] The upper die body 2221 is fixedly connected to the lifting drive device 221. The connection structure between the upper die body 2221 and the lifting drive device 221 is a prior art and will not be elaborated here.

[0044] The outer contour of the bending groove 2222 and the shape of the bending protrusion 212 are "L" shaped, and the bending groove 2222 and the bending protrusion 212 correspond to each other. When the lifting drive device 221 drives the upper die 222 to press down onto the upper die 222, the bending protrusion 212 is received in the bending groove 2222, thereby realizing the bending of the busbar.

[0045] The upper die mounting plane 2223 is provided on one side of the bending groove 2222, and the upper die mounting plane 2223 is horizontally arranged to facilitate the installation of the upper die limit members 2224 provided on the upper die body 2221.

[0046] The two upper die limit members 2224 respectively correspond to the two lower die limit members 214. When the lifting drive device 221 drives the upper die 222 to press down onto the bending lower die 21, the upper die limit members 2224 are inserted into the positioning holes 215 of the lower die limit members 214, thereby realizing the positioning between the upper die 222 and the bending lower die 21.

[0047] The bending protection mechanism 30 includes a feeding mechanism 31 for transporting the protective belt 2, a collecting mechanism 32 for recycling the protective belt 2, and a guiding mechanism 33 provided between the feeding mechanism 31 and the collecting mechanism 32.

[0048] The feeding mechanism 31 includes a feeding drive device 311 and a feeding roller 312 provided on the feeding drive device 311 and used for accommodating the protective belt 2. The feeding drive device 311 drives the feeding roller 312 to rotate, thereby transporting the protective belt 2 on the feeding roller 312 to the guiding mechanism 33 and laying the protective belt 2 on the upper die 222 and the bending lower die 21. The feeding drive device 311 and the feeding roller 312 are both prior arts and will not be elaborated here.

[0049] The material receiving mechanism 32 includes a material receiving driving device 321 and a material receiving roller 322 disposed on the material receiving driving device 321 and used for recovering the protective belt 2. The material receiving driving device 321 drives the material receiving roller 322 to rotate. One end of the protective belt 2 is fixed to the material receiving roller 322. When the material receiving driving device 321 drives the material receiving roller 322 to rotate, the material receiving roller 322 can recover the protective belt 2 laid on the upper die 222 and the bending lower die 21.

[0050] The guiding mechanism 33 includes at least one first guiding roller 331 disposed on one side of the bending mechanism 20 close to the conveying mechanism 10, and at least one second guiding roller 332 disposed on one side of the bending mechanism 20 close to the anti-collision mechanism 40.

[0051] Both ends of the protective belt 2 are respectively fixed to the feeding roller 312 and the material receiving roller 322. The protective belt 2 between the feeding roller 312 and the material receiving roller 322 is disposed between the upper die 222 and the bending lower die 21 through the first guiding roller 331 and the second guiding roller 332, so as to protect the upper die 222 and the bending lower die 21. The first guiding roller 331 guides the protective belt 2 sent out by the feeding mechanism 31 to one side of the second guiding roller 332, and makes the protective belt 2 laid on the upper die 222 of the bending upper die assembly 22, so as to protect the upper die 222 of the bending upper die assembly 22. The second guiding roller 332 flips the protective belt 2 guided by the first guiding roller 331 by 180 degrees, changes the transmission direction of the protective belt 2, makes the protective belt 2 pass through between the bending upper die assembly 22 and the bending lower die 21 again, and transmits it in the direction of the material receiving roller 322, and the protective belt 2 is laid on the bending lower die 21 to protect the bending lower die 21.

[0052] In addition, the protective belt 2 passes through between the two upper die limit members 2224 and the two lower die limit members 214. The two upper die limit members 2224 and the two lower die limit members 214 respectively limit the position of the protective belt 2 on the upper die 222 and the bending lower die 21 to prevent the protective belt 2 from shifting during transmission.

[0053] The anti-collision mechanism 40 includes a mounting frame 41, two guiding rods 42 disposed on the mounting frame 41, two springs 43 disposed on the guiding rods 42, an anti-collision baffle 44 disposed at one end of the guiding rod 42, a limit baffle 45 fixedly connected to the guiding rod 42 opposite to the anti-collision baffle 44, and an adjusting rod 46 disposed between the limit baffle 45 and the mounting frame 41.

[0054] The mounting bracket 41 is the supporting main body of the anti-collision mechanism 40. The guide rod 42, spring 43, anti-collision baffle 44, limit baffle 45, and adjusting rod 46 are mounted on the mounting bracket 41, so that the anti-collision baffle 44 corresponds to the bending mechanism 20. The mounting bracket 41 is a prior art and will not be elaborated here.

[0055] The guide rod 42 is inserted into the mounting bracket 41, and the guide rod 42 can telescopically move on the mounting bracket 41. The guide rod 42 is a prior art and will not be elaborated here.

[0056] The spring 43 is sleeved on the guide rod 42, and the spring 43 is clamped between the mounting bracket 41 and the anti-collision baffle 44. Thus, the spring 43 can drive the anti-collision baffle 44 to reset by its own elastic force. The spring 43 is a prior art and will not be elaborated here.

[0057] The anti-collision baffle 44 is used to abut against one end of the bending mother row to be processed in the bending mechanism 20, and limit the maximum transmission position of the bending mother row to be processed in the bending mechanism 20. In this embodiment, the outer contour of the anti-collision baffle 44 is circular.

[0058] The limit baffle 45 is used to fix one end of the guide rod 42, and the anti-collision baffle 44 is fixed to the other end of the guide rod 42, thereby limiting the position of the guide rod 42 on the mounting bracket 41. The adjusting rod 46 is also arranged on the limit baffle 45 to adjust the distance between the limit baffle 45 and the mounting bracket 41, thereby driving the guide rod 42 to move and adjusting the position of the anti-collision baffle 44.

[0059] The adjusting rod 46 includes an adjusting rod main body 461 inserted into the limit baffle 45, a threaded section 462 arranged at one end of the adjusting rod main body 461 and screwed onto the mounting bracket 41, and a limit protrusion 463 arranged on the adjusting rod main body 461 and abutting against one side of the anti-collision baffle 44.

[0060] The limit protrusion 463 limits the sliding position of the anti-collision baffle 44. Rotate the adjusting rod main body 461, so that the threaded section 462 rotates synchronously to adjust the position of the entire adjusting rod 46, and further drive the guide rod 42 to move and adjust the position of the anti-collision baffle 44.

[0061] When the transmission mechanism 10 transmits the bending mother row to the bending mechanism 20, the limit baffle 45 can abut against one end of the bending mother row to be processed, prevent the excessive transmission position of the bending mother row to be processed, and limit the bending position of the bending mother row to be processed.

[0062] Compared with the prior art, the automated terminal bending system provided by the present invention transports the to-be-bent busbar to the bending mechanism 20 through the transmission mechanism 10, and the bending protection mechanism 30 is used to transport the protection belt 2 into the bending mechanism 20 to protect the to-be-bent busbar from scratches during processing. Among them, the driving device 132 in the transmission mechanism 10 drives the sliding seat 131 to reciprocate along the guide rail 12. The tray assembly 14 loads the to-be-bent busbar and is arranged on the sliding seat 131. Both ends of the rotating shaft 141 in the tray assembly 14 are fixedly connected to the tray 142 and the connecting plate 143 respectively. Thus, when the connecting plate 143 rotates, it drives the rotating shaft 141 to rotate, and synchronously drives the tray 142 to rotate. The pulley 145 is arranged at the free end of the connecting shaft 144, and the pulley 145 is accommodated in the guiding groove 146. Thus, when the pulley 145 slides along the guiding groove 146, the pulley drives the connecting shaft 144 to rotate following the guiding groove 146. Among them, the guiding groove 146 includes a first guiding groove 1461 and a second guiding groove 1462 arranged at one end of the first guiding groove 146 away from the bending mechanism 20. The extending directions of the first guiding groove 1461 and the second guiding groove 1462 are perpendicular to each other. When the transmission mechanism 10 transports the to-be-bent busbar to the bending mechanism 20, the pulley 145 is accommodated in the second guiding groove 1462, with the tray opening 1423 of the tray 142 facing outward. The to-be-bent busbar is clamped and installed in the accommodating groove 1422 by a manipulator. The sliding assembly 13 drives the tray assembly 14 to slide towards the bending mechanism 20, and the pulley 145 slides in the first guiding groove 1461. Since the extending directions of the first guiding groove 1461 and the second guiding groove 1462 are perpendicular to each other, the connecting shaft 144 rotates 90 degrees synchronously, driving the tray opening 1423 of the tray 142 to face the bending mechanism 20, thus facilitating the transfer of the to-be-bent busbar on the tray 142 to the bending mechanism 20. The bending mechanism 20 includes a bending lower die 21 arranged on the workbench 1 and a bending upper die assembly 22 arranged on one side of the bending lower die 21. The feeding mechanism 31 in the bending protection mechanism 30 is used to transport the protection belt 2, and the collecting mechanism 32 is used to recycle the protection belt 2. A guiding mechanism 33 is arranged between the feeding mechanism 31 and the collecting mechanism 32. Among them, the guiding mechanism 33 includes at least one first guiding roller 331 arranged on the side of the bending mechanism 20 close to the transmission mechanism 10 and at least one second guiding roller 332 arranged on the side of the bending mechanism 20 close to the anti-collision mechanism 40.The first guiding roller 331 guides the protective belt 2 sent out by the feeding mechanism 31 to one side of the second guiding roller 332, and makes the protective belt 2 be laid on the upper die 222, so as to realize the protection of the upper die 222.
