[0048] The present invention provides an automatic bending wire body for arranging wires.

[0049] Reference Figures 1 to 10 In one embodiment of the present invention, the automatic bending wire body includes:

[0050] The bending module 1 has a bending station 11, and the workpiece is bent at the bending station 11;

[0051] The material flow module 3 includes a loading line 31, a unloading line 33, and a carrier return line 32. The loading line 31 has a loading position 51, the unloading line 33 has a unloading position 52, and one end of the loading line 31 is a discharge position 53. The loading line 31 is connected to the carrier return line 32 to allow the workpiece carrier 4 to flow back from the carrier return line 32 to the discharge position 53; and

[0052] The material picking module 2 includes a first moving device 21, a material picking structure 22 and a detection module 23. The material picking structure 22 and the detection module 23 are both arranged on the first moving device 21. The first moving device 21 can move between the loading position 51, the bending station 11 and the unloading position 52.

[0053] The technical solution of the present invention adopts the material flow module 3 to load the workpiece, the material picking module 2 loads the workpiece located at the loading position 51 to the bending station 11 of the bending module 1, and the bending module 1 bends the workpiece at the bending station 11. After the bending process is completed, the workpiece becomes a bent part, and the material picking module 2 then sends the bent part to the unloading position 52 for conveying and unloading. The present invention can realize a series of actions such as automatic loading, transferring, bending and unloading of the workpiece through the automated processing of the above structure, thereby improving the efficiency of workpiece bending and thus improving production efficiency. Specifically, the material flow module 3 includes a loading line 31, a unloading line 33 and a carrier return line 32. The loading line 31 is used for loading workpieces, and the loading line 31 is located at the discharge position 53 to place the workpiece carrier 4 loaded with workpieces. The unloading line 33 is used for unloading bent parts. The loading line 31 is connected to the carrier return line 32. In this way, the workpiece carrier 4 can rely on the carrier return line 32 to flow back to the discharge position 53 after completing its function of carrying the workpiece, so as to facilitate the re-discharge of the workpiece carrier 4 and then send it to the loading line 31. As for the material picking module 2, the material picking structure 22 and the detection module 23 of the material picking module 2 can be moved back and forth between the loading position 51, the bending station 11 and the unloading position 52 through the first moving device 21, and the workpiece can be sucked and placed by relying on the material picking structure 22, and the accuracy of the workpiece placement can be detected by using the detection module 23.

[0054] The following describes the automatic bending process of the cable arrangement through specific embodiments. Specifically, the structure of the material flow module 3 and the auxiliary devices and structures provided therein are first introduced. The corresponding relationship between the material flow module 3 and the material retrieving module 2 is then described, and the material retrieving module 2 is then described.

[0055] The material flow module 3 primarily functions to facilitate the flow of workpieces, i.e., loading and unloading them. Furthermore, the workpiece carrier 4 is the primary tool for carrying workpieces in the present invention. Since the workpiece carrier 4 is reusable, the material flow module 3 also requires that the workpiece carrier 4 be recycled to conserve the material.

[0056] Specifically, the loading line 31 is provided with a lifting structure 35, which is located at the loading position 51. The lifting structure 35 is used to lift the workpiece carrier 4 located at the loading position 51 for the material to be retrieved by the retrieving structure 22. Furthermore, the lifting bracket 351 is provided with an escape channel 350. When the lifting bracket 351 lifts the workpiece carrier 4, the escape channel 350 is flush with the loading line 31, allowing other workpiece carriers 4 to flow downward along the loading line 31. That is, the jacking structure 35 lifts the workpiece that needs to be bent and the workpiece carrier 4 carrying the workpiece, and the material-picking module 2 moves the workpiece on the workpiece carrier 4. At this time, since the jacking bracket 351 of the jacking structure 35 is provided with an avoidance channel 350, and after the jacking structure 35 rises, the avoidance channel 350 is flush with the loading line 31, so that the workpiece carrier 4 arranged upstream of the loading line 31 can continue to move toward the flow direction of the loading line 31, so that the jacking structure 35 can achieve the jacking effect of the workpiece carrier 4 without affecting the normal operation of the loading line 31.

[0057] Specifically, in this embodiment, the lifting structure 35 includes a lifting bracket 351 that passes through the loading line 31 and a lifting cylinder 352 that is located at the bottom of the loading line 31 and connected to the lifting bracket 351. A first mounting bracket 353 is provided on one side of the lifting bracket 351, and a limiting cylinder 354, an adjustment cylinder 356, and a positioning cylinder 358 are mounted on the first mounting bracket 353.

[0058] Furthermore, the limiting cylinder 354 is arranged at one end of the first mounting bracket 353 toward the downstream of the loading line 31, and the limiting cylinder 354 is connected to the limiting member 355, and the limiting cylinder 354 drives the limiting member 355 to move toward the direction of the lifting bracket 351 to limit the workpiece carrier 4; it can be understood that when the bending module 1 requires the workpiece to be bent, the limiting cylinder 354 drives the limiting member 355 to limit the workpiece carrier 4 located at the loading position 51, thereby preventing the workpiece carrier 4 from continuing to flow downstream of the loading line 31.

[0059] Furthermore, the adjustment cylinder 356 and the positioning cylinder 358 are both provided on one side of the lifting bracket 351. The adjustment cylinder 356 is connected to an adjustment block 357. The adjustment cylinder 356 drives the adjustment block 357 to move toward the lifting bracket 351 to abut against the side edge of the workpiece carrier 4, thereby adjusting the position of the workpiece carrier 4. It should be noted that if the position of the workpiece carrier 4 is offset to a certain extent, the adjustment block 357 can push against the side edge of the workpiece carrier 4 to restore the workpiece carrier 4 to the correct position, thereby facilitating the subsequent positioning of the workpiece carrier 4.

[0060] Furthermore, the positioning cylinder 358 is connected to a positioning pin 359, and a positioning hole 41 is also provided on the side wall of the workpiece carrier 4. The positioning cylinder 358 drives the positioning pin 359 to move toward the lifting bracket 351 to insert into the positioning hole 41, thereby positioning the workpiece carrier 4, so that the workpiece carrier 4 can be accurately located at the loading position 51, so that the material picking structure 22 can smoothly move the workpiece into the bending station 11.

[0061] To prevent unprocessed workpieces and the workpiece carriers 4 carrying them from flowing to the carrier return line 32, the loading line 31 is further provided with a buffer structure 34, which is located upstream of the lifting structure 35. The buffer structure 34 in the loading line 31 temporarily stops the workpiece carriers 4 on the loading line 31 during operation, preventing them from continuing to flow along with the flow of the loading line 31.

[0062] Specifically, the buffer structure 34 includes a second mounting bracket 340, and the second mounting bracket 340 is provided with a first blocking cylinder 341 and a second blocking cylinder 343 at intervals along the flow direction of the loading assembly line 31. The first blocking cylinder 341 is connected to a first blocking block 342, and the second blocking cylinder 343 is connected to a second blocking block 344. It should be noted that the first blocking cylinder 341 is used to block a workpiece carrier 4 to prevent the workpiece carrier 4 from continuing to flow, while the second blocking cylinder 343 is used to block other workpiece carriers 4 upstream of the workpiece carrier 4 to prevent collisions between the workpiece carriers 4, which may cause damage to the workpiece carrier 4 or cause the workstation on the workpiece carrier 4 to shift, thereby affecting the material retrieving process of the retrieving structure 22.

[0063] The function of the picking module 2 is to pick up the workpiece from a specified position or place the workpiece to a specified position.

[0064] Specifically, the retrieving structure 22 in the retrieving module 2 includes a third mounting bracket 221 and a slide cylinder 222. The third mounting bracket 221 is rotatably mounted on the first moving device 21. Slide cylinders 222 are provided on opposite sides of the third mounting bracket 221. The movable portion of the slide cylinder 222 is connected to at least a first suction nozzle 223 and a second suction nozzle 224. The first suction nozzle 223 and the second suction nozzle 224 are arranged in parallel and face downward. In this embodiment, the first suction nozzle 223 and the second suction nozzle 224 jointly suck the workpiece, enabling the retrieving structure 22 to pick up the workpiece. The workpiece in this embodiment has a workpiece body and long and short lines connected to the workpiece body. The first suction nozzle 223 needs to suck the workpiece body, and the second suction nozzle 224 needs to suck the long lines. In this way, the workpiece can be stably sucked by the first suction nozzle 223 and the second suction nozzle 224 together, and the picking structure can stably suck the workpiece while also stably placing the workpiece in the bending station 11.

[0065] Furthermore, at least one of the bending modules 1 and one of the material-picking modules 2 form a bending station 11. One bending station 11 can complete the bending of one or more workpieces. In this embodiment, one bending station 11 is correspondingly provided with one material-picking module 2 and two bending modules 1. One material-picking module 2 can simultaneously load two bending modules 1, thereby improving the working efficiency of the entire automatic bending line.

[0066] In this embodiment, the automatic bending line is provided with a plurality of bending stations 11, which are arranged in parallel along the flow direction of the loading line 31. The plurality of bending stations 11 can work simultaneously to improve the working efficiency of the entire automatic bending line.

[0067] It should be noted that, in this embodiment, the material flow module 3 further includes a transfer structure 36 , which is disposed between the loading line 31 and the carrier return line 32 , and the workpiece carrier 4 can be recovered and recycled through the transfer structure 36 .

[0068] In one embodiment, the transfer mechanism 36 can manually move the workpiece carrier 4 from the loading line 31 to the unloading line 33. To further improve the efficiency of the transfer mechanism 36, the transfer mechanism 36 includes a second movable device 361 and a push plate 362 connected to the second movable device. The second movable device 361 moves the push plate 362 back and forth between the loading line 31 and the carrier return line 32. The second movable device 361 automates the movement of the workpiece carrier 4, saving manpower and improving work efficiency.

[0069] As for the bending module 1, the bending module 1 is a modular device that specifically implements the bending process of the workpiece, which is usually achieved by a cylinder and bending blocks of different shapes to achieve the bending effect of the workpiece.

[0070] The present invention also provides a method for operating a wire body, which adopts the aforementioned automatic bending wire body. The specific structure of the automatic bending wire body is referred to the above embodiment. Since this method for operating a wire body adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. The method for operating a wire body includes the following steps:

[0071] The loading line 31 transports the workpiece carrier 4 containing the workpiece from the discharge position 53 to the loading position 51;

[0072] The first moving device 21 moves to the loading line 31 and aligns the picking structure 22 with the loading position 51, so that the picking structure 22 can take out the workpiece located in the workpiece carrier 4. The workpiece carrier 4 with the workpiece taken out enters the carrier return line 32 and returns to the discharge position 53.

[0073] The first moving device 21 moves to the bending module 1 and aligns the material taking structure 22 with the bending station 11 so that the material taking structure 22 places the workpiece on the bending station 11;

[0074] The first moving device 21 aligns the detection module 23 with the bending station 11 so that the detection module 23 detects whether the workpiece is accurately placed in the bending station 11;

[0075] When the detection module 23 determines that the workpiece is accurately placed in the bending station 11, the bending module 1 bends the workpiece to obtain a bent part.

[0076] The first moving device 21 aligns the material taking structure 22 with the bending station 11 and takes out the bent part;

[0077] The first moving device 21 moves to the unloading line 33 and aligns the picking structure 22 with the unloading position 52 so that the picking structure 22 can place the bent part at the unloading position 52 .
