Description

Technical Field

[0001] This invention relates to the field of automated equipment and mechanical devices, and in particular to a flat wire bundling and feeding mechanism. Background Technology

[0002] After the metal flat wire machine rolls the round metal wire into flat wire, it needs to be wound into a coil and bundled for easy storage and transportation. To ensure that the coil does not loosen during handling, it usually needs to be bundled multiple times around the circumference of the coil.

[0003] Currently, there are two main methods for bundling flat wire rolls. The first is a purely manual method, where operators manually thread the binding round wire through the center of the flat wire roll, then tie and lock it. This method suffers from low efficiency, high labor costs, high labor intensity, and inconsistent bundling quality due to variations between individuals.

[0004] The second method involves using semi-automatic or simple equipment. While this method partially replaces manual labor, it still has significant drawbacks in practical applications. For example, the wire feeding process lacks effective guidance and straightening, causing round wires to easily wobble and bend, resulting in incomplete wire feeding; the reliability of the binding action is insufficient, with poor coordination in key steps such as clamping, cutting, and knotting, leading to frequent failures; simultaneously, existing equipment typically lacks efficient roll positioning and conversion mechanisms, requiring manual intervention or equipment pauses after each binding to adjust the roll position, making continuous, fully automated multi-bundle operations difficult. Furthermore, locking after binding often still requires manual intervention, resulting in low automation.

[0005] Therefore, existing flat wire bundling technologies generally suffer from low automation, poor stability, low efficiency, and the inability to achieve continuous automated multi-pass bundling, which restricts the improvement of the overall efficiency of flat wire production lines. Summary of the Invention

[0006] This invention provides a flat wire bundling and feeding mechanism that can fully automate the flat wire roll bundling process, replace manual labor, and solve the problems of low efficiency and inability to continuously and stably complete multiple bundling operations of existing equipment.

[0007] To address the aforementioned problems, this invention provides a flat wire bundling and feeding mechanism, configured in conjunction with a rotating exchange device. The rotating exchange device has multiple positioning grooves for limiting the flat wire roll. These positioning grooves rotate via the rotating exchange device, including: A wire feeding device is located on one side of the rotating exchange device. The wire feeding device is used to feed the round wire and feeds the round wire to the positioning groove. A round wire binding device is positioned above the positioning groove. The round wire binding device fixes the round wire and binds the flat wire roll through the round wire binding device.

[0008] The flat wire bundling and feeding mechanism provided by this invention has, but is not limited to, the following beneficial effects compared to the prior art: By coordinating the rotation exchange device, the wire feeding device, and the round wire binding device, the core processes such as positioning of flat wire rolls, conveying of round wires, and binding and fixing can be completed without manual intervention. This completely replaces the semi-automatic binding method in the existing technology that relies on manual labor or has poor stability, greatly reducing manpower input and avoiding efficiency fluctuations and human errors caused by manual operation.

[0009] The rotating exchange device can switch between multiple positioning grooves to realize the alternation of work positions for flat wire rolls to be bundled, flat wire rolls in the process of bundling, and flat wire rolls that have already been bundled. In conjunction with the continuous action of the wire feeding device and the round wire bundling device, the gap between processes is reduced. At the same time, the automated operation mode does not require manual rest or operation adjustment, which greatly shortens the bundling cycle of a single roll of flat wire.

[0010] The positioning groove of the rotating exchange device is precisely matched with the flat wire roll, achieving stable positioning of the flat wire roll and preventing displacement during the binding process; the wire feeding device directionally conveys the round wire, and the round wire binding device accurately completes the fixing and binding action of the round wire. The closed-loop operation structure formed by the three ensures that the binding position and binding force of each roll of flat wire are uniform and consistent, effectively solving the problems of loose binding, positional deviation, and uneven tightness that exist in manual binding or binding of existing equipment, and improving the quality stability of the finished flat wire roll.

[0028] like Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a flat wire bundling and feeding mechanism, including a rotating exchange device 100, a wire feeding device 200, and a round wire bundling device 300. The rotating exchange device 100 is provided with a plurality of positioning grooves 101, which are used to limit the flat wire roll. The plurality of positioning grooves 101 are rotated by the rotating exchange device 100. The wire feeding device 200 is located on one side of the rotating exchange device 100 and is used to feed the round wire. The wire feeding device 200 feeds the round wire to the positioning groove 101. The round wire bundling device 300 is located above the positioning groove 101 and fixes the round wire. The round wire is used to bundle the flat wire roll.

[0029] In actual operation, after the flat wire roll is completed, it is transferred by the winding mechanism to the positioning groove 101 on the rotary exchange device 100. The positioning groove 101 limits and fixes the flat wire roll and precisely positions it, so that the flat wire roll will not be dislodged from the positioning groove 101 when the rotary exchange device 100 rotates. Subsequently, the wire feeding device 200 is activated, pushing the round wire to the positioning groove 101 of the rotary exchange device 100. When the round wire moves to this position, the round wire binding device 300 above the round wire moves down. After the round wire passes through the flat wire roll, the round wire binding device 300 first grabs the round wire, lifts it, and rotates the round wire binding device 300 so that the rotation of the round wire binds the flat wire roll, thus completing the overall operation process of the device.

[0030] In this embodiment of the application, the rotating exchange device 100 includes a rotating disk 102 and an end cover 105. The rotating disk 102 is vertically rotatably mounted on a base plate 103. A guide rod cylinder 104 is provided on one side of the rotating disk 102. The end cover 105 is located on the other side of the rotating disk 102. The end cover 105 corresponds to the guide rod cylinder 104. The end cover 105 has a positioning groove 101, and the output end of the guide rod is located in the positioning groove 101.

[0031] In the above structure, the main body of the rotary exchange device 100 is a vertically arranged rotary disk 102. The rotary disk 102 is rotated by a drive motor. A guide rod cylinder 104 is arranged on one side of the rotary disk 102. The guide rod cylinder 104 is fixed on the rotary disk 102, and the output end of the guide rod cylinder 104 passes through the rotary disk 102 and is located on the other side of the rotary disk 102. An end cover 105 is arranged on the other side of the rotary disk 102. The end cover 105 is positioned corresponding to the guide rod cylinder 104. A positioning groove 101 is provided on the end cover 105. The size and shape of the positioning groove 101 match the size and shape of the flat wire roll, so that the positioning groove 101 effectively fixes and limits the flat wire roll, preventing the flat wire roll from shifting or falling off during the rotation of the rotary disk 102. When the flat wire roll is transferred to the positioning groove 101, the guide rod cylinder 104 can push the end cover 105 to realize the linear movement of the flat wire roll, which facilitates the matching process between the flat wire roll and the round wire and ensures that stable and reliable positioning can be provided during the bundling process of the flat wire roll.

[0032] Specifically, a support rod 106 is also provided at the output end of the guide rod cylinder 104. The support rod 106 moves linearly through the guide rod cylinder 104 and is located in the positioning groove 101. The support rod 106 is used to support the flat wire roll, so that the flat wire roll is located in the positioning groove 101. The positioning groove 101 and the support rod 106 limit the flat wire roll.

[0033] In this embodiment, the wire feeding device 200 includes a wire storage wheel 201, a straightening device 202, and a pusher mechanism 203. The round wire is wound on the wire storage wheel 201. The straightening device 202 is located on one side of the wire storage wheel 201, and the round wire is straightened by the straightening device 202. The pusher mechanism 203 is located between the straightening device 202 and the positioning groove 101, and the pusher mechanism 203 pushes the round wire into the positioning groove 101.

[0034] In the above structure, the round wire is pre-wound on the wire storage wheel 201. During release, it passes sequentially through the vertical straightening wheel group 2021 and the horizontal straightening wheel group 2022 to achieve bidirectional straightening, eliminate bending stress, and ensure the straightness of the wire feeding. The push rod mechanism 203 is located between the outlet of the straightening device 202 and the positioning groove 101, and is responsible for accurately pushing the straightened round wire into the center hole of the coil.

[0035] In this embodiment, the straightening device 202 includes vertical straightening wheels 2021 and horizontal straightening wheels 2022. Multiple vertical straightening wheels 2021 are provided, and the multiple vertical straightening wheels 2021 are staggered. The circular wire is vertically straightened by the multiple vertical straightening wheels 2021. Multiple horizontal straightening wheels 2022 are provided, and the multiple horizontal straightening wheels 2022 are staggered. The circular wire is horizontally straightened by the multiple horizontal straightening wheels 2022.

[0036] In the above structure, the straightening device 202 employs a multi-set staggered straightening wheel structure. The vertical straightening wheels 2021 are spaced apart along the vertical plane, and the centerlines of adjacent vertical straightening wheels 2021 are offset horizontally, forming a wave-shaped vertical straightening channel 307. When the round wire is drawn from the wire storage wheel 201, it first enters the set of vertical straightening wheels 2021. The multiple staggered vertical straightening wheels 2021 apply alternating vertical pressure to the round wire, gradually eliminating the bending deformation of the round wire in the vertical plane, thus achieving vertical straightening. Next, the round wire, after preliminary vertical straightening, enters the set of horizontal straightening wheels 2022. The horizontal straightening wheels 2022 are spaced apart along the horizontal plane, and the centerlines of adjacent horizontal straightening wheels 2022 are offset vertically, forming a wave-shaped horizontal straightening channel 307. The round wire is subjected to alternating lateral pressure within the 2022 set of horizontal straightening rollers, further eliminating its bending deformation in the lateral plane and ultimately achieving ideal straightness, laying the foundation for subsequent precise wire feeding and bundling operations. This bidirectional multi-wheel straightening design can comprehensively correct various bends generated during the storage and transportation of the round wire, ensuring that the wire does not deviate, entangle, or jam during feeding, significantly improving the stability and accuracy of wire feeding.

[0037] In this embodiment, the push rod mechanism 203 includes a drive assembly 2031, a transmission guide assembly 2032, and a round wire push rod 2033. The drive assembly 2031 includes a feeding motor 20311, a drive wheel 20312 driven by the feeding motor 20311, and a pressure wheel 20313 disposed opposite to the drive wheel 20312 to clamp the round wire. The transmission guide assembly 2032 includes a synchronous transmission mechanism 20321 connected to the drive assembly 2031, and a mounting base 20322 connected to the synchronous transmission mechanism 20321 and capable of reciprocating along the wire feeding direction under its drive. The round wire push rod 2033 is fixedly mounted on the mounting base 20322, and has a guide channel inside for the round wire to pass through. The axial extension direction of the round wire push rod 2033 points towards the positioning groove 101 on the rotary exchange device 100.

[0038] In the above structure, the drive assembly 2031 serves as the power source for the push rod mechanism 203. It drives the drive wheel 20312 to rotate via the feeding motor 20311. The drive wheel 20312 cooperates with the pressure roller 20313 to clamp and convey the round wire, ensuring stable and continuous forward conveying. The feeding motor 20311 can be speed-adjusted according to actual wire feeding requirements to control the wire conveying speed and quantity. The pressure roller 20313 typically applies pressure through an elastic component, ensuring it fits tightly against the drive wheel 20312. This guarantees adaptable clamping of round wires of different diameters while avoiding excessive compression damage to the wire surface. The elastic component can be a spring, with the spring force directed towards the direction of the round wire.

[0039] The transmission guide assembly 2032 is responsible for the linear motion of the round wire push rod 2033. The synchronous transmission mechanism 20321 can adopt high-precision transmission methods such as synchronous belt drive or ball screw drive to ensure that the reciprocating movement of the mounting base 20322 in the wire feeding direction has high positioning accuracy and smooth movement.

[0040] The inner diameter of the guide channel in the round wire pusher 2033 matches the diameter of the round wire, ensuring smooth passage of the wire and providing precise guidance to prevent radial deviation during feeding. The front axis of the round wire pusher 2033 points to the center of the positioning groove 101 on the rotary exchange device 100, ensuring that when the mounting base 20322 moves the round wire pusher 2033 forward, the round wire can be accurately pushed to the center of the flat wire roll in the positioning groove 101, preparing for subsequent binding operations. After one wire feeding is completed, the synchronous transmission mechanism 20321 drives the mounting base 20322 and the round wire pusher 2033 to quickly reset, awaiting the next wire feeding command. The entire pusher mechanism 203 operates smoothly and efficiently, significantly improving the automation and accuracy of wire feeding.

[0041] In this embodiment, the round wire binding device 300 includes a Z-axis linear module 301, an elastic gripper 302, wire cutters 303, a round wire lifting cylinder 304, and a round wire rotating cylinder 305. The elastic gripper 302 is installed at the output end of the Z-axis linear module 301 and is used to clamp and fix the round wire. The wire cutters 303 are disposed on one side of the elastic gripper 302 and are used to cut the round wire. The round wire lifting cylinder 304 is disposed above the elastic gripper 302 and is connected to the elastic gripper 302. The round wire lifting cylinder 304 pushes the elastic gripper 302 to move closer. The round wire rotating cylinder 305 is connected to the round wire lifting cylinder 304 and is used to drive the round wire to rotate to complete the knot binding.

[0042] In the above structure, the Z-axis linear module 301 provides power and guidance for the vertical movement of the round wire binding device 300, and core execution components such as the elastic gripper 302 are slidably mounted on its linear track. When the wire feeding device 200 pushes the round wire to the center of the flat wire roll in the positioning groove 101, the Z-axis linear module 301 drives the elastic gripper 302 to move downward to the position of the round wire. The elastic gripper 302 opens and closes under the drive of the round wire lifting cylinder 304. When it moves to the position of the round wire, the round wire lifting cylinder 304 first drives the elastic gripper 302 to open. After the round wire enters the gripper's holding range, the round wire lifting cylinder 304 acts again to drive the elastic gripper 302 to close reliably, thereby firmly clamping the round wire. After clamping, the round wire lifting cylinder 304 drives the elastic gripper 302 to lift upward, so that the round wire passes through the center of the flat wire roll and is pulled upward, providing sufficient operating space for subsequent rotation binding. Next, the circular wire rotary cylinder 305 is activated. Its output shaft is connected to the circular wire lifting cylinder 304 and the elastic gripper 302, driving the entire elastic gripper 302 assembly to rotate horizontally. During rotation, the gripped circular wire winds around the outer circumference of the flat wire roll as the elastic gripper 302 rotates. By setting the number of rotations (usually 1-3 rotations depending on the diameter of the flat wire roll and the bundling requirements), a tight bundling of the flat wire roll is achieved. After bundling, the wire cutter 303, located on one side of the elastic gripper 302, is activated. The wire cutter 303 can be driven by an independent cylinder, and its blade precisely aligns with the excess portion of the bound circular wire, cutting it off and completing the bundling process of one flat wire roll. Subsequently, the Z-axis linear module 301 drives the elastic gripper 302 and other components to reset, awaiting the bundling command for the next flat wire roll. The entire round wire bundling device 300 achieves efficient and precise automated bundling of flat wire rolls through a series of continuous actions, including the lifting of the Z-axis linear module 301, the clamping of the elastic gripper 302, the lifting of the round wire lifting cylinder 304, the rotation of the round wire rotating cylinder 305, and the cutting of the wire cutter 303.

[0043] During the above process, when the round wire is moved to the corresponding position by the round wire pusher 2033, the round wire can be cut first by the wire cutter 303, which facilitates the binding of the round wire to the flat wire roll.

[0044] In order to facilitate the processing of round wires, the elastic gripper 302 and the wire cutter 303 are both driven by corresponding independent driving components.

[0045] In this embodiment of the application, the elastic gripper 302 is provided with an elastic clamping opening, the elastic clamping opening includes at least two relatively movable gripper pieces 3021, a channel 307 for the circular wire to pass through is formed between the gripper pieces 3021, and an elastic element is provided on the gripper piece 3021, the elastic element pushes the gripper piece 3021 to clamp the circular wire.

[0046] The main body of the elastic gripper 302 is a metal base, and its lower end is provided with two relatively movable gripper pieces 3021. The gripper pieces 3021 are made of spring steel, which has good elasticity and wear resistance. The two gripper pieces 3021 have arc-shaped clamping surfaces on their relatively inner sides. The radius of the arc surface is adapted to the diameter of the round wire, and the clamping surface is provided with anti-slip texture to enhance the friction with the round wire and prevent the round wire from slipping.

[0047] A channel 307 is formed between the gripper piece 3021 and the elastic gripper 302 to allow the round wire to pass through. The initial width of the channel 307 is slightly larger than the diameter of the round wire so that the round wire can smoothly enter the clamping area. The upper end of the channel 307 is the arc-shaped clamping surface of the gripper piece 3021, which facilitates the smooth entry of the round wire. An elastic element is connected between the upper part of each gripper piece 3021 and the metal base. The elastic element is a compression spring. One end of the spring is fixed in the mounting hole of the metal base, and the other end abuts against the side of the gripper piece 3021 to provide a continuous clamping preload for the gripper piece 3021.

[0048] When the round wire enters from the lower end of the channel 307, the round wire exerts a radial thrust on the arc-shaped clamping surface of the gripper 3021, forcing the gripper 3021 to open slightly to both sides, and the spring is compressed; when the round wire is fully in the clamping position, the elastic restoring force of the spring pushes the gripper 3021 to move towards each other, tightly clamping the round wire between the arc-shaped surfaces. The clamping force can be adapted to round wires of different diameters by adjusting the preload of the spring; this elastic structure ensures that the round wire is always stably clamped during the conveying process, while avoiding damage to the round wire due to excessive clamping force.

[0049] In this embodiment, a curved guide groove structure 306 is provided above the elastic gripper 302. The curved guide groove structure 306 is connected to the elastic gripper 302, and the elastic gripper 302 moves closer under the drive of the round wire lifting cylinder 304. The curved guide groove structure 306 includes a curved groove 3061 formed on the elastic gripper 302 or a component fixedly connected to it, and a fixedly provided guide pin 3062, which extends into the curved groove 3061.

[0050] In the above structure, the curved guide groove structure 306 is provided with two groove structures, which are respectively set at the positions of the elastic gripper 302. A guide pin 3062 is fixedly set at the root position of the elastic gripper 302. The guide pin 3062 moves in the curved groove 3061, and its movement is driven by the round wire lifting cylinder 304.

[0051] In the specific structure, the curved guide groove structure 306 is fixedly set at the fixed end of the z-axis linear module. When it moves, the elastic gripper 302 and the curved guide groove structure 306 generate relative movement. Since the curved guide groove structure 306 is fixedly set, the elastic gripper 302 moves through the two groove structures to achieve the clamping movement trend, which facilitates the round wire to come together and makes it easier to tie later.

[0052] In this embodiment, an auxiliary locking device 400 is also included. The auxiliary locking device 400 is disposed on one side of the rotating exchange device 100 and is used to bend and lock the bundled round wire. The auxiliary locking device 400 includes a push-pull cylinder 401 and an auxiliary locking cylinder 402. The push-pull cylinder 401 is used to move the auxiliary locking claw 403 to the position of the bundled round wire. The auxiliary locking cylinder 402 is used to drive the auxiliary locking claw 403 to rotate, bending and locking the round wire.

[0053] The auxiliary locking device 400 in this embodiment is used to lock the knotted round wire a second time to ensure a firm binding. Its specific structure and working method are as follows: The auxiliary locking device 400 is fixed to one side of the rotating exchange device 100 by a bracket, corresponding to the binding position of the positioning groove 101. Its core components include a push-pull cylinder 401, an auxiliary locking cylinder 402, and an auxiliary locking claw 403.

[0054] The axis of the push-pull cylinder 401 is parallel to the radial direction of the rotation exchange device 100. It is fixed on the bracket by the cylinder seat. The slider of the push-pull cylinder 401 is fixedly connected to the cylinder body of the auxiliary locking cylinder 402. It can drive the auxiliary locking cylinder 402 to move back and forth in the horizontal direction to realize the position switching of the auxiliary locking claw 403.

[0055] The auxiliary locking cylinder 402 is a linear drive cylinder. Its housing is fixed to the slider of the push-pull cylinder 401. The output shaft is connected to the auxiliary locking claw 403 through the transmission of gear 404 and rack 405. The auxiliary locking claw 403 consists of two metal claws arranged opposite each other. The ends of the claws are provided with arc-shaped grooves that are adapted to the round wire. The inner wall of the arc-shaped grooves is provided with anti-slip teeth to enhance the biting force with the round wire.

[0056] Workflow: ① After the round wire binding device 300 completes the knotting, the push-pull cylinder 401 is activated, pushing the auxiliary locking cylinder 402 and the auxiliary locking claw 403 to move towards the vertical round wire until the round wire is embedded in the arc-shaped groove of the auxiliary locking claw 403. ② When the auxiliary locking cylinder 402 is activated, it drives the auxiliary locking claw 403 to rotate 30°-45° through the gear 404 and rack 405 transmission mechanism, bending the vertical round wire to an inclined angle to achieve secondary locking and prevent the knot of the round wire from loosening; ③ After locking is completed, the auxiliary locking cylinder 402 rotates in the opposite direction to reset, and the push-pull cylinder 401 drives the auxiliary locking device 400 to move in the opposite direction to return to its original position, waiting for the next locking action; this auxiliary locking process is seamlessly connected with the action of the round wire binding device 300, further improving the binding firmness of the flat wire roll and meeting the transportation and storage requirements.

[0057] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
