[0039] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0040] Please refer to Figures 1 to 18 The fully automated electronic detonator production line includes a conveyor belt and a transport vehicle 100 driven by the conveyor belt. It also includes an automatic winding and shifting device 1, a wire end shaping device 2, a stripping and separating wire shaping device 3, a twisting device 4, an injection molding device 5, an inner sheath stripping device 6, a riveting device 7, a laser welding device 8, a base tube feeding and clamping device 9, and a detonator packaging assembly 10 arranged sequentially along one side of the conveyor belt. On the other side of the conveyor belt, a junction box lower cover assembly device 20 and a junction box upper cover assembly device 30 are arranged sequentially. The junction box lower cover assembly device 20 and the junction box upper cover assembly device 30 are both located between the stripping and separating wire shaping device 3 and the detonator packaging assembly 10.

[0041] The automatic winding and transfer device 1 is used to wind the cable into a bundle and place the bundle on the transport vehicle 100;

[0042] The wire end straightening device 2 is used to straighten the ends of the wire bundles on the transport vehicle 100;

[0043] The stripping and shaping device 3 is used to strip the outer sheath of the two ends of the wire bundle and separate the two core wires at the ends of the wire bundle.

[0044] The twisting device 4 is used to twist the two core wires at the end of the wire bundle so that the two wires are intertwined.

[0045] The injection molding equipment 5 is used to perform injection molding on one end of the wire bundle and form an injection molded body at that end.

[0046] The inner skin peeling device 6 is used to peel off the inner skin of the end of the wire bundle having one end of the injection molded body;

[0047] The riveting device 7 is used to rivet a chip tip assembly to one end of the wire bundle having the injection-molded body.

[0048] The laser welding equipment 8 is used to weld and reinforce the riveting joint between the wire bundle and the chip tip assembly;

[0049] The base tube feeding bayonet device 9 is used to fit the base tube onto the outside of the chip head assembly and fix the base tube to the injection molded body bayonet;

[0050] The junction box lower cover assembly device 20 is used to assemble and connect the end of the wire bundle away from the injection molded body to the junction box lower cover;

[0051] The junction box cover assembly device 30 is used to assemble and close the junction box cover with the junction box bottom cover.

[0052] The detonator packaging assembly 10 is used to package finished electronic detonators.

[0053] As can be seen from the above description, the beneficial effects of the present invention are as follows: the fully automatic electronic detonator production line can realize the fully automated production and packaging of electronic detonators without the need for manual assistance, which helps to improve production efficiency and ensure the personal safety of workers.

[0054] Furthermore, an injection molding inspection device 40 is provided between the injection molding equipment 5 and the inner skin peeling device 6.

[0055] As described above, the injection molding testing equipment 40 can test the injection quality of the injection molded body at the end of the wire.

[0056] Furthermore, a welding inspection device 50 is also provided between the laser welding equipment 8 and the base pipe feeding gate device 9.

[0057] As described above, the welding inspection equipment 50 can inspect the welding quality of the wire end and the chip tip assembly.

[0058] Furthermore, the detonator packaging assembly 10 is also provided with an appearance inspection device 60 and a defective product ejection device 70 in front of it, with the defective product ejection device 70 located between the appearance inspection device 60 and the detonator packaging assembly 10.

[0059] As described above, the defective product ejection device 70 can eject the transport carrier 100 loaded with defective products such as injection molding defects, welding defects, and appearance defects from the conveyor belt, thereby preventing defective products from entering the packaging stage and ensuring the quality of the products leaving the factory.

[0060] Furthermore, a pipe marking device 80 is also provided between the base pipe feeding gate device 9 and the appearance inspection device 60.

[0061] As described above, the pipe marking device 80 can mark the outer wall of the base pipe, which facilitates later traceability.

[0062] Furthermore, the junction box cover assembly equipment 30 is also equipped with a cover marking device 90 at the corresponding position.

[0063] As described above, the top cover coding device 90 can code the top wall of the top cover, which facilitates later traceability.

[0064] Furthermore, the transport vehicle 100 has multiple fixing structures 1002 at both ends for clamping and fixing the cable ends, and the fixing structures 1002 at both ends of the transport vehicle 100 are arranged in a one-to-one correspondence. Each fixing structure 1002 includes a first elastic element 10022, a base 10021, and a clamping block 10023 arranged opposite to each other. The top surface of the base 10021 is provided with a receiving groove 100211. A portion of the clamping block 10023 is located in the receiving groove 100211 and is rotatably connected to the receiving groove 100211. The first elastic element 10022 abuts against the clamping block 10023 and the base 10021 respectively.

[0065] As described above, unlike the existing transport fixtures for transporting electronic detonator wire bundles that use a horizontally opening and closing clamping structure 1002, the clamping structure 1002 on this transport carrier 100 opens and closes by rotation to clamp the wire end of the bundle. This effectively reduces the overall volume of the clamping structure 1002. Furthermore, the rotating clamping block 10023 will not be jammed due to falling wire debris, allowing the clamping structure 1002 to work stably for extended periods. The small-volume clamping structure 1002 on the transport carrier 100 allows for the installation of a greater number of clamping structures 1002 without increasing the overall volume of the transport carrier 100. This effectively enhances the transport capacity of the transport carrier 100 for carrying wire bundles, thereby improving the production efficiency of the production line using this transport carrier 100.

[0066] Furthermore, the base 10021 is provided with a limiting member 10025, which is located between the two clamping blocks 10023. The clamping blocks 10023 abut against the limiting member 10025. The limiting member 10025 is rod-shaped. The two clamping blocks 10023 are respectively provided with grooves 100234 on their sides that are close to each other. The grooves 100234 are provided corresponding to the limiting member 10025.

[0067] As described above, the limiting member 10025 can limit the rotation angle of the two clamping blocks 10023 in the closing direction, ensuring that the gap between the two clamping blocks 10023 is in a preset position when unloaded, without deviation, so that the wire end of the subsequent wire can be accurately inserted between the two clamping blocks 10023; the groove 100234 can avoid a part of the limiting member 10025, making the width of the fixing structure 1002 smaller.

[0068] Furthermore, the conveyor belt is a double-layer conveyor line, and there are multiple automatic winding and transferring devices 1. Each automatic winding and transferring device 1 includes a frame 11, on which a winding and binding assembly 12 and a feeding device 13 are provided. The frame 11 is also provided with an infeed assembly 14, a lifting assembly 15, a positioning assembly 16, and an outfeed assembly 17. The frame 11 has a recessed portion located below the feeding device 13. The infeed assembly 14 and the lifting assembly 15 are respectively located inside the recessed portion, and the positioning assembly 16 and the outfeed assembly 17 are respectively located on the table surface of the frame 11.

[0069] As described above, the automatic winding and transfer device 1 has a novel structure. Compared with the existing automatic winding and transfer device 1, which requires the fully loaded transport fixture to be moved out before the empty transport fixture can be moved back into the transport fixture placement position, the transfer component 14 in this automatic winding and transfer device 1 can pre-move the empty transport fixture onto the lifting component 15, enabling efficient circulation of the transport fixture and greatly reducing the waiting time for moving the transport fixture in and out. It is particularly suitable for application scenarios where a double-layer conveyor line is equipped with multiple automatic winding and transfer devices 1, effectively improving the production efficiency of the fully automatic electronic detonator production line and helping to save production costs.

[0070] Furthermore, the twisting device 4 includes a rotary drive mechanism 41, a base plate 421, a fixed plate 422, a second push plate 423, a first Y-axis drive member 431, and a twisting assembly 44. The fixed plate 422 and the first Y-axis drive member 431 are respectively disposed on the base plate 421. The first Y-axis drive member 431 is connected to the second push plate 423 to drive the second push plate 423 to move closer to or away from the fixed plate 422. The twisting assembly 44 includes a rotating drum 441, an X-shaped gripper 442, and a second elastic... The rotating drum 441 is rotatably mounted on the fixed plate 422. The X-shaped gripper 442 is located at the end of the rotating drum 441 away from the second push plate 423. The second elastic member 443 is used to drive the X-shaped gripper 442 to open. The abutment member 444 is rotatably mounted on the second push plate 423. The end of the abutment member 444 near the fixed plate 422 has an abutment portion 4441 for driving the X-shaped gripper 442 to close. The rotary drive mechanism 41 is used to drive the rotating drum 441 to rotate.

[0071] As described above, the twisting device 4 has a novel structure and a compact size. Compared with the existing gripper cylinder, the twisting component 44 in the twisting device 4 occupies a significantly smaller width in the X-axis direction required for rotation. This allows the twisting device 4 with the same width to carry a larger number of twisting components 44, thereby enabling the twisting device 4 to complete the twisting of more wire ends of wire bundles in one operation. This is beneficial for improving the production efficiency of the production line and reducing production costs.

[0072] Example 1

[0073] Please refer to Figures 1 to 18 Embodiment 1 of the present invention is: a fully automatic electronic detonator production line, used for fully automated production of finished electronic detonators and packaging of finished electronic detonators.

[0074] Please combine Figure 1 , Figure 2 and Figure 7 The fully automatic electronic detonator production line includes a conveyor belt and a transport vehicle 100 driven by the conveyor belt. The conveyor belt is a double-layer conveyor line. The upper conveyor line is used to transport the loaded transport vehicle 100, and the lower conveyor line is used to transport the unloaded transport vehicle 100.

[0075] The transport vehicle 100 can be a transport vehicle 100 of the prior art, such as the transport fixture disclosed in Chinese Utility Model No. CN210026042U. However, in order to increase the carrying capacity of the transport vehicle 100 and ensure the stability of its operation, please combine with... Figures 2 to 4 In this embodiment, the transport vehicle 100 includes a body 1001, with fixing structures 1002 at both ends. Each fixing structure 1002 includes a first elastic element 10022, a base 10021, and opposing clamping blocks 10023. The top surface of the base 10021 has a receiving groove 100211. A portion of the clamping block 10023 is located within the receiving groove 100211 and is rotatably connected to it. The first elastic element 10022 abuts against both the clamping block 10023 and the base 10021. Specifically, the clamping block 10023 is rotatably connected to the base 10021 via a pivot 10024.

[0076] The main body 1001 has multiple fixing structures 1002 on both sides, and the fixing structures 1002 on one side of the main body 1001 correspond one-to-one with the fixing structures 1002 on the other side of the main body 1001. Two corresponding fixing structures 1002 clamp and fix the two ends of the same cable bundle. In this embodiment, the transport fixture has a carrying capacity of ten cable bundles, which doubles the carrying capacity compared to existing transport fixtures that can only transport five cable bundles at a time.

[0077] The first elastic element 10022 is a torsion spring, a spring sheet, a compression spring, or a spring pad, and the spring pad may be made of rubber material. In this embodiment, the first elastic element 10022 is a compression spring.

[0078] like Figure 4As shown, to limit the position of the first elastic member 10022 and improve the structural stability of the fixing structure 1002, the clamping block 10023 is provided with a first mounting groove 100231, and the base 10021 is provided with a second mounting groove 100212. One end of the first elastic member 10022 is located in the first mounting groove 100231, and the other end of the first elastic member 10022 is located in the second mounting groove 100212. To allow the first elastic member 10022 to better bear the force, in this embodiment, the compression direction of the first elastic member 10022 is set at an acute angle to the bottom surface of the base 10021, that is, the axial direction of the first elastic member 10022 intersects the bottom surface of the base 10021, but is not perpendicular to it.

[0079] Preferably, the two clamping blocks 10023 are respectively provided with clamping grooves 100232 on the side that are close to each other. More preferably, the wall surface of the clamping grooves 100232 is an arc surface.

[0080] To facilitate the insertion of the wire end of the cable into the space between the two clamping blocks 10023, a guide surface 100233 is provided on the inner side of the top of the clamping block 10023. The guide surface 100233 can be either an inclined surface or an arc surface.

[0081] Furthermore, the base 10021 is provided with a limiting member 10025, which is located in the receiving groove 100211 and between the two clamping blocks 10023. When the two clamping blocks 10023 are not clamping the end of the wire handle, the clamping blocks 10023 abut against the limiting member 10025. In this embodiment, the limiting member 10025 is rod-shaped, and the two clamping blocks 10023 are respectively provided with grooves 100234 on the side that are close to each other. The grooves 100234 are provided corresponding to the limiting member 10025. Specifically, the limiting member 10025 is located above the center of the line connecting the two rotating shafts 10024, that is, the limiting member 10025 and the two rotating shafts 10024 are arranged in a triangle. In this way, the two rotating shafts 10024 can be brought closer to each other, so that the fixing structure 1002 can be further miniaturized.

[0082] The two clamping blocks 10023 each have a limiting arm 100235 protruding outward on the side away from each other. When the clamping block 10023 rotates outward to a certain extent, the limiting arm 100235 interferes with the base 10021, thereby preventing the clamping block 10023 from continuing to rotate. This helps to avoid the clamping block 10023 from being over-expanded, which would cause the first elastic element 10022 to be over-compressed.

[0083] To prevent foreign objects from entering the receiving groove 100211 through the gap between the limiting arm 100235 and the base 10021, a blocking portion 100236 is provided at the suspended end of the limiting arm 100235. The blocking portion 100236 is located on the outer side of the side wall of the base 10021. In this embodiment, the blocking portion 100236 is formed by bending downward from the suspended end of the limiting arm 100235.

[0084] The base 10021 and the body 1001 have a positioning structure on their mating surfaces. The positioning structure includes a cooperating positioning post 100213 and a positioning groove 1621. In this embodiment, the positioning post 100213 is located on the base 10021 and the positioning groove 1621 is located on the body 1001. In other embodiments, the positioning groove 1621 can be located on the base 10021, and in this case, the positioning post 100213 is located on the body 1001.

[0085] like Figure 1 As shown, the fully automatic electronic detonator production line also includes an automatic winding and shifting device 1, a wire end shaping device 2, a stripping and separating wire shaping device 3, a twisting device 4, an injection molding device 5, an inner sheath stripping device 6, a riveting device 7, a laser welding device 8, a base tube feeding and clamping device 9, and a detonator packaging assembly 10, arranged sequentially along one side of the conveyor belt. On the other side of the conveyor belt, a junction box lower cover assembly device 20 and a junction box upper cover assembly device 30 are arranged sequentially. The junction box lower cover assembly device 20 and the junction box upper cover assembly device 30 are both located between the stripping and separating wire shaping device 3 and the detonator packaging assembly 10. One end of the transport carrier 100 also has a plurality of injection molding lower molds that cooperate with the injection molding device 5. The plurality of injection molding lower molds are arranged one-to-one with the plurality of fixed structures 1002 at one end of the body 1001.

[0086] Please combine Figure 1 , Figures 5 to 7The automatic winding and transferring device 1 is used to wind cables into bundles and place the bundles on the transport carrier 100. Multiple automatic winding and transferring devices 1 are available. The automatic winding and transferring device 1 can be an existing type, such as the automatic winding and transferring device 1 disclosed in Chinese Utility Model No. CN209480158U. However, to improve the production efficiency of the fully automated electronic detonator production line, this embodiment improves the way the automatic winding and transferring device 1 inputs and outputs to the transport carrier 100. Specifically, the automatic winding and transferring device 1 includes a frame 11, on which a winding and binding assembly 12 is provided. The machine includes a feeding device 13, a transfer assembly 14, a lifting assembly 15, a positioning assembly 16, and a transfer assembly 17; the winding and binding assembly 12 includes a wire feeding device, a winding device, a binding device, and a transfer device. The wire feeding device is used to feed wire to the winding device, the winding device is used to wind the wire into a bundle, the transfer device is used to transfer the bundle to the binding device, and the binding device is used to bind the bundle; the frame 11 has a recessed portion located below the feeding device 13, the transfer assembly 14 and the lifting assembly 15 are respectively located within the recessed portion, and the positioning assembly 16 and the transfer assembly 17 are respectively located on the table surface of the frame 11. The transfer component 14 is used to transfer the empty transport vehicle 100 of the lower layer in the double-layer conveyor line to the lifting component 15. The lifting component 15 is used to lift the empty transport vehicle 100 to a preset position. The positioning component 16 is used to position and fix the transport vehicle 100. The feeding device 13 is used to move the wire bundle bound by the binding device to the transport vehicle 100 positioned by the positioning component 16. The removal component 17 moves the transport vehicle 100 with the wire bundle to the upper layer in the double-layer conveyor line.

Similarly, the second Y-axis translation drive 171, the X-axis translation drive 161, the first lifting drive 142, the second lifting drive 163, the third lifting drive 152, and the fourth lifting drive are also optional.

[0091] The working process of the automatic winding and shifting device 1 is briefly described as follows: After the first Y-axis translation drive 141 drives the first lifting drive 142 to a position close to the double-layer conveyor line, the first lifting drive 142 drives the first hook plate 143 to rise or fall, so that the first positioning post 100213 is inserted into the positioning hole of the transport carrier 100 located on the lower layer of the double-layer conveyor line.

[0094] Please combine Figure 1 , Figures 8 to 18 The twisting device 4 is used to twist the two core wires at the end of the wire bundle so that the two wires are intertwined. The twisting device 4 can be a wire twisting device in the prior art, such as the wire twisting device disclosed in Chinese Utility Model No. CN210552617U. However, in order to reduce the size of the twisting device 4 and make it more suitable for the transport vehicle 100 of this embodiment, please refer to... Figures 8 to 11 In this embodiment, the twisting device 4 includes a rotary drive mechanism 41, a base plate 421, a fixed plate 422, a second push plate 423, a first Y-axis drive member 431, and a twisting assembly 44. The fixed plate 422 and the first Y-axis drive member 431 are respectively disposed on the base plate 421. The fixed plate 422 and the second push plate 423 are arranged parallel to each other. The first Y-axis drive member 431 is connected to the second push plate 423 to drive the second push plate 423 to move closer to or away from the fixed plate 422. The twisting assembly 44 includes a rotating drum 441, an X-shaped gripper 442, and a second spring. The rotating drum 441 is rotatably mounted on the fixed plate 422. An X-shaped gripper 442 is located at the end of the rotating drum 441 away from the second push plate 423. The second elastic member 443 drives the X-shaped gripper 442 to open. The abutment member 444 is rotatably mounted on the second push plate 423, and the end of the abutment member 444 near the fixed plate 422 has an abutment portion 4441 for driving the X-shaped gripper 442 to close. A rotary drive mechanism 41 drives the rotating drum 441 to rotate. The rotating drum 441 is a cylindrical structure with both ends open. A first Y-axis drive member 431 drives the second push plate 423 to move along the Y-axis direction. The first Y-axis drive member 431 can be an electric push rod, a cylinder, a hydraulic rod, or other drive mechanism.

[0095] In detail, the fixed plate 422 is provided with a first mounting hole, and the end of the rotating cylinder 441 away from the second push plate 423 passes through the first mounting hole. A first bearing 4451 is fitted on the rotating cylinder 441, and the rotating cylinder 441 is rotatably mounted on the fixed plate 422 via a first rotating shaft 10024. The second push plate 423 is provided with a second mounting hole 4231, and a portion of the abutment member 444 is located within the second mounting hole 4231. A second bearing 4452 is fitted on the abutment member 444, and the abutment member 444 is rotatably mounted on the second push plate 423 via the second bearing 4452. It should be noted that, in order to allow the reader to clearly see the second mounting hole 4231, the abutment member 444 and the second bearing 4452 are separated from the second push plate 423 in the figure. In the actual product, the second bearing 4452 should be located within the second mounting hole 4231, and the abutment member 444 should be fitted within the second bearing 4452.

[0096] Please combine Figures 11 to 14 The X-shaped gripper 442 includes a first gripper 4421, a second gripper 4422, and a mounting shaft 4423. The first gripper 4421 and the second gripper 4422 are rotatably connected by the mounting shaft 4423. The mounting shaft 4423 is located inside the rotating drum 441, and both ends of the mounting shaft 4423 are mounted on the rotating drum 441. One end of the first gripper 4421 away from the second push plate 423 and one end of the second gripper 4422 away from the second push plate 423 respectively extend out of the rotating drum 441. The other ends of the first gripper 4421 and the second gripper 4422 respectively cooperate with the abutment part 4441. The second elastic member 443 contacts the first gripper 4421 and the second gripper 4422 respectively.

[0097] In a preferred embodiment, the contact portion 4441 is a concave conical surface located at the end of the contact member 444. By adjusting the driving distance of the first Y-axis drive member 431, the tightening degree of the X-shaped gripper 442 can be adjusted, thereby enabling this twisting device to be applicable to cables of different diameters. Therefore, this twisting device has the advantage of high versatility.

[0098] Further preferably, the outer wall of the first claw 4421 has a mating cone surface 4424 that mates with the concave cone surface. Similarly, the outer wall of the first claw 4421 has a mating cone surface 4424 that mates with the concave cone surface. When the X-shaped gripper 442 opens to its maximum extent under the action of the second elastic member 443, a portion of the first claw 4421 and a portion of the second claw 4422 respectively abut against the inner wall of the rotating cylinder 441. The presence of the mating cone surface 4424 ensures that there is a gap between the end of the first claw 4421 near the second push plate 423 (and the end of the second claw 4422 near the second push plate 423) and the inner wall of the rotating cylinder 441, allowing the end of the contact member 444 near the fixed plate 422 to be inserted, thereby ensuring the working stability of the twisting assembly 44. Meanwhile, the concave conical surface and the mating conical surface 4424 are in surface contact, which can prevent excessive wear of the first claw 4421 / second claw 4422 in certain areas, thus preventing a decrease in the service life of the twisted wire assembly 44.

[0099] The second elastic element 443 can be a spring, a sheet spring, a torsion spring, or a spring washer. In this embodiment, a spring is selected as the second elastic element 443 in the twisted wire assembly 44. To facilitate the installation of the spring and to prevent accidental displacement of the spring during operation, the first claw 4421 is provided with a first mounting groove 44211, and the second claw 4422 is provided with a second mounting groove 44221. One end of the second elastic element 443 is located in the first mounting groove 44211, and the other end of the second elastic element 443 is located in the second mounting groove 44221.

[0100] like Figure 9 and Figure 10 As shown, the rotary drive mechanism 41 can be either a belt drive mechanism or a gear drive mechanism. In this embodiment, there are multiple twisted wire components 44 arranged in a row. The rotary drive mechanism 41 includes a rotary drive component 411, a driving gear 412, multiple transmission gears 413, and multiple driven gears 414. The driven gears 414 are mounted on the rotating drum 441, and the transmission gears 413 are rotatably mounted on the fixed plate 422. Two adjacent driven gears 414 are driven by a transmission gear 413. The rotary drive component 411 is connected to the driving gear 412. The driving gear 412 directly meshes with the nearest driven gear 414, or is connected via a transmission gear 413. The rotary drive component 411 can be a motor.

[0101] Please combine Figure 8 and Figure 9The twisting device further includes a fixing frame 45, on which a wire end clamping mechanism 46 is provided.

The second Y-axis drive member 432 is connected to the base plate 421 to drive the twisting assembly 44 to move closer to or away from the wire end clamping mechanism 46. The second Y-axis drive member 432 is used to drive the base plate 421 to move along the Y-axis direction. The second Y-axis drive member 432 can be an electric push rod, a cylinder, a hydraulic rod, or other drive mechanism.

[0102] Please combine Figure 15 and Figure 17 In this embodiment, the wire end clamping mechanism 46 includes a base plate 461, a driving assembly, a third elastic element 462, a first fixing strip 463, and a second fixing strip 464. The base plate 461 is connected to the fixing frame 45 and is parallel to the fixing plate 422. The first fixing strip 463 is provided with a first gripper 4651, and the second fixing strip 464 is rotatably provided with a second gripper 4652. The third elastic element 462 contacts the second fixing strip 464 and the second gripper 4652 respectively. The driving assembly is disposed on the base plate 461 and drives the first fixing strip 463 and the second fixing strip 464 to slide so as to drive the first gripper 4651 and the second gripper 4652 to open and close. The first gripper 4651, the second gripper 4652, and the wire twisting assembly 44 are arranged in a one-to-one correspondence.

[0103] In detail, the driving assembly includes a first X-axis driving member 4661 and a second X-axis driving member 4662. The first X-axis driving member 4661 is fixed on the substrate 461 and connected to the first fixing bar 463. The second X-axis driving member 4662 is fixed on the substrate 461 and connected to the second fixing bar 464. The first X-axis driving member 4661 drives the first fixing bar 463 to move linearly along the X-axis to move the first gripper 4651 closer to or away from the second gripper 4652. The second X-axis driving member 4662 drives the second fixing bar 464 to move linearly along the X-axis to move the second gripper 4652 closer to or away from the first gripper 4651. When the first X-axis drive 4661 moves the first gripper 4651 closer to the second gripper 4652, and the second X-axis drive 4662 moves the second gripper 4652 closer to the first gripper 4651, the first gripper 4651 and the second gripper 4652 close to hold and fix the area near the end of the cable bundle. When the first X-axis drive 4661 moves the first gripper 4651 away from the second gripper 4652, and the second X-axis drive 4662 moves the second gripper 4652 away from the first gripper 4651, the first gripper 4651 and the second gripper 4652 open to release the area near the end of the cable bundle. The first X-axis drive 4661 can be an electric actuator, a cylinder, a hydraulic cylinder, or other drive components. Similarly, the second X-axis drive 4662 can also be an electric actuator, a cylinder, a hydraulic cylinder, or other drive components.

[0104] Please combine Figure 17 and Figure 18 To limit the rotation angle range of the second gripper 4652 and ensure the working stability of the wire end clamping mechanism 46, a limiting groove 4641 is provided on the second fixing bar 464, and a portion of the second gripper 4652 is located within the limiting groove 4641. In this embodiment, the second fixing bar 464 is located between the first fixing bar 463 and the substrate 461, and the limiting groove 4641, which connects the top and bottom surfaces of the second fixing bar 464, is provided on the side of the second fixing bar 464 closest to the first fixing bar 463. Optionally, the second gripper 4652 and the second fixing bar 464 are rotatably connected by a rotating shaft 10024, which is located within the limiting groove 4641.

[0105] The second fixing bar 464 is provided with a connecting block 4642. The third elastic element 462 is connected to one end of the second gripper 4652 and the connecting block 4642 respectively to drive the other end of the second gripper 4652 closer to the first gripper 4651. In this embodiment, the connecting block 4642 is fixed to the top of the second fixing bar 464 by screws. In other embodiments, the connecting block 4642 and the second fixing bar 464 can be an integral structure formed by one-piece machining. In addition, in other embodiments, torsion springs, springs, spring sheets, spring washers, etc. can also be used as the third elastic element 462.

[0106] Please combine Figure 15 and Figure 17 Specifically, the first fixing bar 463 is provided with multiple first clamping claws 4651, and the second fixing bar 464 is provided with multiple second clamping claws 4652. The number of first clamping claws 4651 and the number of second clamping claws 4652 are arranged in a one-to-one correspondence. The number of third elastic elements 462 is also multiple and is arranged in a one-to-one correspondence with the second clamping claws 4652. In this embodiment, the number of first clamping claws 4651, second clamping claws 4652, and twisting components 44 are all ten. The elastic clamping and fixing structure 1002, composed of the first clamping claws 4651, second clamping claws 4652, and third elastic elements 462, can stably clamp and fix the wire ends. When the first fixing bar 463 and the second fixing bar 464 slide towards each other, the wire ends of each wire bundle can be stably clamped by the corresponding elastic clamping and fixing structure 1002, avoiding the phenomenon of unstable clamping of individual wire ends due to factors such as processing tolerances.

[0107] In a preferred embodiment, a guide plate 467 is further provided on the substrate 461. The guide plate 467 has a guide groove 4671 on the side closest to the substrate 461, and the first fixing strip 463 and / or the second fixing strip 464 are located within the guide groove 4671. The guide plate 467 effectively protects the first fixing strip 463 and / or the second fixing strip 464, reducing the likelihood of the first fixing strip 463 and / or the second fixing strip 464 being impacted by external objects or contaminated by dust, thus ensuring the operational and structural stability of the wire end clamping mechanism 46.

[0108] The wire end clamping mechanism 46 further includes a fifth lifting drive component 4681 disposed on the fixed frame 45, and the base plate 461 is connected to the fixed frame 45 through the fifth lifting drive component 4681. The fifth lifting drive component 4681 may be an electric push rod, a cylinder, a hydraulic cylinder, or other driving components. In this way, the first gripper 4651 and the second gripper 4652 can lift and lower to avoid the wire end of the horizontally conveyed wire bundle. It is readily understood that in other embodiments, the fifth lifting drive component 4681 may not be provided.

[0109] Please combine Figure 15 and Figure 17 To facilitate subsequent processing, the twisting device may optionally include a wire end bending mechanism 469. This mechanism 469 includes a sixth lifting drive 4691 and a bending plate 4692. The sixth lifting drive 4691 is located on the side of the base plate 461 away from the first fixing strip 463 and is connected to the bending plate 4692. The sixth lifting drive 4691 can be an electric push rod, a cylinder, a hydraulic cylinder, or other driving components. Preferably, the bending plate 4692 has a wire pressing groove 46921, which prevents the wire end of the wire bundle from shifting along the X-axis.

[0110] The working process of this wire twisting device 4 is briefly described as follows: After the wire end of the wire bundle is moved to the preset position, the fifth lifting drive unit 4681 drives the base plate 461 to descend, so that the wire end is located between the first clamp 4651 and the second clamp 4652. The drive assembly drives the first clamp 4651 and the second clamp 4652 to close, thereby clamping the rear area of ​​the wire end; the second Y-axis drive unit 432 drives the fixing plate 422 to approach the first clamp 4651, so that the wire end enters between the first clamp 4421 and the second clamp 4422. Then, the first... Y-axis drive 431 drives the second push plate 423 to move closer to the fixed plate 422, causing the end of the contact member 444 near the fixed plate 422 to extend into the rotating drum 441 and the concave conical surface to abut against the mating conical surface 4424, thereby pressing the second elastic member 443. The X-shaped gripper 442 clamps the wire end. Then, rotation drive 411 drives the rotating drum 441 to rotate (during the rotation of the rotating drum 441, the contact member 444 also rotates with the rotating drum 441), causing the wire end to twist. Next, the first Y-axis drive 431 drives the second push plate 423 to move away from the fixed plate 422, causing the X-shaped gripper 442 to release the twisted wire end; the second Y-axis drive 432 drives the base plate 421 to move the fixed plate 422 away from the first gripper 4651. Then, the sixth lifting drive 4691 drives the bending plate 4692 to descend to bend the twisted wire end and reset it. Finally, the fifth lifting drive 4681 drives the base plate 461 to rise, completing the entire twisting action.
