[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] like Figures 1 to 3 As shown, this embodiment of the invention provides an integrated wire cutting and changing device compatible with multiple wire specifications, comprising: a frame; a wire cutting guide rail 20, which is mounted on the frame and has a wire cutting guide rail slider 22; a tool holder 2, which is connected to the wire cutting guide rail slider 22 and has a cutting tool 1 mounted on it; a ball screw assembly 7, which is mounted on the frame and connected to a ball screw motor 8; a connecting plate 9, which is mounted on the ball screw assembly 7; and a push-pull pneumatic... Cylinder 10, the push-pull cylinder 10 is mounted on the connecting plate 9; linear guide rail 16, the linear guide rail 16 is mounted on the connecting plate 9, and a linear guide rail slider 17 is fitted on the linear guide rail 16; wire storage limiting block 5, the wire storage limiting block 5 is located on the linear guide rail slider 17 and connected to the push-pull cylinder 10, and the wire storage limiting block 5 is provided with a wire stop post 4, a wire feeding roller 6, a wire feeding length measuring wheel 18, a front guide post 14 and a rear guide post 12; miniature electric cylinder 15, the miniature electric cylinder 15 is connected to the wire stop post 4.

[0047] In this embodiment, the frame serves as a support, the wire-cutting guide rail 20 is mounted on the frame, and a wire-cutting guide rail slider 22 is fitted on the wire-cutting guide rail 20. The wire-cutting guide rail 20 is fixedly connected to the frame via a wire-cutting guide rail support plate 21. The tool holder 2 is connected to the wire-cutting guide rail slider 22, and a cutting tool 1 is mounted on the tool holder 2. A ball screw assembly 7 is mounted on the frame and connected to a ball screw motor 8. A connecting plate 9 is mounted on the ball screw assembly 7, a push-pull cylinder 10 is mounted on the connecting plate 9, and a linear guide rail 16 is mounted on the connecting plate 9. A linear guide slider 17 is fitted on the guide rail 16. The wire storage limiting block 5 is located on the linear guide slider 17 and connected to the push-pull cylinder 10. The wire storage limiting block 5 is provided with a wire stop post 4, a wire feeding roller 6, a wire feeding length measuring wheel 18, a front guide post 14, and a rear guide post 12. The wire storage limiting block 5 is connected to the push-pull cylinder 10 through a connecting plate 9. The front end of the wire storage limiting block 5 has an open hole, which is fitted with the wire stop post 4. The wire stop post 4 is provided with a wire through hole. The miniature electric cylinder 15 is connected to the wire stop post 4.

[0048] In this embodiment, the wire feeding module comprises a wire storage limiting block 5, a wire stop post 4, a wire feeding roller 6, a front guide post 14, a rear guide post 12, a wire feeding length measuring wheel 18, a miniature electric cylinder 15, and a rear support block 13. This module is used for straightening, conveying, and temporarily storing multi-specification wires. The inner diameter of the wire storage limiting block 5 is designed to match different wire diameters to ensure smooth conveying of wires of corresponding sizes. The wire storage limiting block 5 has an open hole at its front end, which mates with the wire stop post 4. The wire stop post 4 has a wire through hole and connects to the miniature electric cylinder 15. During the threading process, the miniature electric cylinder 15 is pushed out a certain distance by programming, aligning the axis of the through hole in the wire stop post 4 with the axis of the through hole in the wire storage limiting block 5, thus enabling threading. After the conductor reaches the predetermined position, the miniature electric cylinder 15 is retracted, driving the conductor stop post 4 to move, thereby achieving relative fixation of the conductor. To ensure the integrity of the conductor, a force control sensor is integrated into the miniature electric cylinder 15 to control the force, thus ensuring that the conductor is not damaged by compression. The rear support block 13 integrates the wire feeding roller 6, the rear guide post 12, and the wire feeding length measuring wheel 18 together. The wire feeding roller 6 and the wire feeding length measuring wheel 18 together realize the passive conveying of the conductor, and calculate the wire feeding length through the wire feeding length measuring wheel 18 to achieve online detection, transmitting the detection data to the system for recording.

[0049] In this embodiment, the ball screw assembly 7, ball screw motor 8, connecting plate 9, push-pull cylinder 10, and connecting block 11 constitute the wire-changing module. The wire-changing module mainly consists of the ball screw assembly 7, ball screw motor 8, connecting plate 9, push-pull cylinder 10, and connecting block 11, and is used for the translational switching, extension, and retraction of multiple specifications of wire-feeding modules. Specifically, the three specifications of wire-feeding modules in this invention are connected together to the connecting plate 9, and then connected to the ball screw assembly 7 through the connecting plate 9. By controlling the ball screw motor 8 to drive the ball screw assembly 7, the horizontal translation of different specifications of wire-feeding modules is achieved. When a certain specification of wire needs to be delivered, the wire-changing module will translate the corresponding wire-feeding module to the delivery position. Simultaneously, all wire-feeding modules are connected to the push-pull cylinder 10 through the connecting block 11. When the wire feeding module needs to be in operation, the push-pull cylinder 10 operates and pushes out the corresponding wire feeding module, thereby ensuring that the front end position of the wire in the working state is different from that in the non-working state of the wire feeding module, so as to facilitate the clamping and cutting of the wire and achieve a better cutting effect.

[0050] In this embodiment, the wire cutting module comprises a cylinder 3, a wire cutting guide rail 20, a wire cutting guide rail support plate 21, a wire cutting guide rail slider 22, a cutting tool, and a cutting tool holder 2. The wire cutting module, consisting of the cylinder 3, wire cutting guide rail 20, wire cutting guide rail support plate 21, wire cutting guide rail slider 22, cutting tool, and cutting tool holder 2, achieves efficient wire cutting. The cutting tool 1 is connected to the cylinder 3 via the cutting tool holder 2. The cutting tool holder 2 is connected to the wire cutting guide rail slider 22, which is mounted on the wire cutting guide rail 20, enabling smooth, low-resistance lateral movement of the cutting tool. The wire cutting guide rail support plate 21 supports all the above structures and connects the wire cutting module to the multi-specification wire feeding module, thereby ensuring the wire cutting effect.

[0051] In another embodiment of the present invention, a method for using a multi-specification wire changing and cutting integrated device is provided, comprising: during use, a micro electric cylinder 15 is driven by an electric cylinder controller to lift the wire stop post 4, aligning the axis of the wire through hole of the wire stop post 4 with the axis of the through hole of the wire storage limiting block 5. The operator inserts the wire of the corresponding specification through the rear guide post 12, through the wire storage limiting block 5, and out 10mm through the front guide post 14. After completing the above operation, the micro electric cylinder 15 is controlled to drive the wire stop post 4 to retract, thereby fixing the wire within the wire storage limiting block 5. The micro electric cylinder 15 integrates a force sensor, and by setting a relevant force value, it prevents the wire stop post 4 from damaging the wire. When it is necessary to complete the feeding operation of the corresponding specification wire, the control system controls the ball screw motor 8 to rotate, and drives the ball screw pair 7 to move, thereby realizing the lateral movement of the wire feeding modules of different specifications fixed on the connecting plate 9, and matching the corresponding wire feeding module with the wire cutting area formed by the wire cutting blade 1 in the wire cutting module. After completing the above actions, the push-pull cylinder 10 is controlled to operate, pushing out the wire feeding module fixed on the linear guide slider 17. After the pushing action is completed, the robotic arm clamping mechanism clamps the front end of the wire, and the control system controls the micro electric cylinder 15 to lift the wire stop post 4 and release the wire, allowing the wire to move freely inside the wire storage limit block 5. During the wire laying process, the wire feeding length measuring wheel 18 integrated at the rear end of the wire feeding module works synchronously, recording the length of the wire fed out in real time, and uploading the recorded data to the central control software for recording, thereby realizing online data detection during the wire feeding process. After the wire feeding action is completed, the cylinders 3 on both sides of the wire cutting module are controlled to move, and the tool holder 2 is driven to move laterally in the opposite direction, so that the wire is quickly cut by the cutting tool 1 fixed on the tool holder 2. After the wire cutting action is completed, the control system controls the micro electric cylinder 15 to retract the wire stop post 4 and fix the wire, ensuring that the wire passes through the front guide post 14 by 10mm, so that the robotic arm clamping mechanism can clamp the wire again. After fixing the wire, control the push-pull cylinder 10 to retract the wire feeding module fixed on the linear guide slider 17 and complete all wire feeding and cutting operations.

[0052] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0053] It has high integration and small space occupation, making it easy to integrate into cabling systems;

[0054] It has a high degree of standardization and flexibility, and the wire feeding module is easy to replicate to meet the wire feeding and cutting needs of different specifications and sizes.

[0055] It can meet the requirements of online detection and data recording of all wire lengths in cabling tasks, which facilitates quality management.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
