Description

Technical Field

[0001] This invention relates to the field of flat wire motor manufacturing technology, and in particular to a wire twisting mechanism and a stator winding device. Background Technology

[0002] Stator winding is a critical process in motor manufacturing, involving winding insulated wires into the stator slots of equipment such as motors, generators, or transformers to create an electromagnetic field. After winding, the stator usually has multiple copper wire ends pre-formed. These ends need to be twisted into a spiral shape and then soldered together to form a single terminal to ensure the reliability and stability of the electrical connection.

[0003] Currently, this wire twisting operation is mainly done manually. Specifically, the flat wire ends of each phase are manually twisted into a spiral shape and then soldered to form a single terminal. However, for thicker copper wires, manual twisting presents significant resistance and is laborious. Secondly, manual twisting makes it difficult to ensure a tight fit between the copper wires, easily resulting in large gaps and unsightly shapes, affecting connection quality.

Detailed Implementation

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] This application discloses a wire twisting mechanism and a stator winding device, such as... Figure 1 and Figure 2As shown, the twisting mechanism includes a fixed base 10, a first slide block 20, and a twisting assembly 30. The fixed base 10 is provided with a first slide rail 11 along the x-axis. The first slide block 20 is slidably mounted on the first slide rail 11. A first driving member 21 is provided on the first slide block 20. The twisting assembly 30 is located on the first slide block 20 and is connected to the first driving member 21. The twisting assembly 30 includes a first clamping member 31 and a second clamping member 32 arranged opposite to each other. A twisting station 33 is formed between the first clamping member 31 and the second clamping member 32. The first clamping member 31 and the second clamping member 32 move towards each other to clamp flat wires. The first driving member 21 drives the twisting assembly 30 to rotate, thereby winding multiple flat wires into a twisted shape.

[0042] In use, the fixed base 10 has an extended first slide rail 11 along the x-axis. The first slide block 20 is slidably mounted on the first slide rail 11. A first driving member 21 is integrated on the first slide block 20. The output end of the first driving member 21 is connected to the twisting assembly 30, which can drive the twisting assembly 30 to complete the rotation action. The twisting assembly 30 is fixedly mounted on the first slide block 20 and includes a first clamping member 31 and a second clamping member 32 arranged opposite and symmetrically. A twisting station 33 for accommodating flat wires is formed between the first clamping member 31 and the second clamping member 32. The first clamping member 31 and the second clamping member 32 can achieve synchronous movement towards each other. When multiple flat wires are placed in the twisting station 33, the first clamping member 31 and the second clamping member 32 move towards each other and fit tightly against the surface of the flat wires, achieving a stable clamping of the ends of the flat wires.

[0043] In use, at the initial stage of operation, the first slide block 20 is in the initial position of the first slide rail 11, and the first clamping member 31 and the second clamping member 32 are separated from each other. During operation, the first driving member 21 is activated to drive the first slide block 20 to slide along the first slide rail 11 towards the flat wire until the ends of multiple flat wires are precisely inserted into the twisting station 33. Subsequently, the first clamping member 31 and the second clamping member 32 move synchronously towards each other to firmly clamp the ends of the flat wires. After clamping, the first driving member 21 drives the ends of the flat wires clamped by the first clamping member 31 and the second clamping member 32 to rotate together. Through the rotation action with a preset duration and preset speed, multiple flat wires are synchronously wrapped around each other, finally forming a regular and uniformly sized twisted structure. After the twisting is completed, the first drive member 21 stops rotating, the first clamping member 31 and the second clamping member 32 move in opposite directions to release the clamping of the flat wire, and the first slide block 20 resets along the first slide rail 11 under the drive of the first drive member 21, completing one twisting operation and waiting for the next round of operation.

[0044] This wire twisting mechanism automates the twisting of multiple flat wires, effectively replacing the traditional manual twisting operation. It solves the problems of low efficiency, high labor intensity, and unstable twisting quality that exist in manual operation, improves the production efficiency and product qualification rate of wire twisting operations, and reduces labor production costs.

[0045] In this embodiment, the relative positions of the first clamping member 31 and the second clamping member 32 can be adaptively adjusted according to the specifications and dimensions of the flat wire to meet the clamping requirements of flat wires of different widths and thicknesses. At the same time, the dimensions of the twisting station 33 match the overall cross-sectional dimensions of the multiple flat wires to ensure that the multiple flat wires can be placed stably in the station and do not shift or fall off during the twisting process.

[0046] In one implementation, such as Figure 2 and Figure 3 As shown, the wire twisting assembly 30 further includes a first fastener 34 and a second fastener 35; the first fastener 34 is connected to the first clamping member 31, and the second fastener 35 is connected to the second clamping member 32; the end of the first fastener 34 near the second fastener 35 is provided with a first inclined surface 341; the end of the second fastener 35 near the first fastener 34 is provided with a second inclined surface 351; the first inclined surface 341 and the second inclined surface 351 are adapted to each other; wherein, when the first clamping member 31 and the second clamping member 32 move relative to each other, the first inclined surface 341 and the second inclined surface 351 are used to press and position the flat wire.

[0047] Specifically, the first fastener 34 is disposed on the end face of the first clamping member 31, and the second fastener 35 is disposed on the end face of the second clamping member 32. At the same time, the end of the first fastener 34 facing the second fastener 35 has a first inclined surface 341, and the end of the second fastener 35 facing the first fastener 34 has a second inclined surface 351. The inclination angle and contour curvature of the first inclined surface 341 and the second inclined surface 351 are adapted to each other to form a wedge-shaped fit structure that fits tightly. This wedge-shaped fit structure is linked to the movement of the first clamping member 31 and the second clamping member 32.

[0048] In actual use, as the first clamping member 31 and the second clamping member 32 move in opposite directions and gradually approach and clamp the ends of the flat wires, the first fastener 34 and the second fastener 35 move synchronously in opposite directions, causing the first inclined surface 341 and the second inclined surface 351 to gradually come into contact and tighten. Relying on the guiding and pressing action of the first inclined surface 341 and the second inclined surface 351, a precise clamping and positioning effect can be achieved on the multiple flat wires placed in the twisting station 33, effectively tightening and organizing the initially loosely arranged flat wires, keeping them in a tightly fitted state, laying the foundation for the subsequent twisting process. After the flat wires are tightened, the first driving member 21 drives the twisting assembly 30 to rotate, simultaneously twisting the tightened flat wires into a twisted structure.

[0049] The coordinated clamping and positioning by the first inclined surface 341 and the second inclined surface 351 ensures that the multiple flat wires are subjected to uniform force throughout the twisting process, effectively avoiding abnormal situations such as displacement of a single flat wire or imbalance of force. This prevents quality problems such as irregular shape and dimensional deviation of the twisted structure, providing a stable and reliable guarantee for the quality of wire twisting and further improving the consistency and accuracy of product forming. At the same time, the first inclined surface 341 and the second inclined surface 351 further ensure that the clamping force is uniform and controllable, which can effectively avoid damage to the surface of the flat wire caused by excessive clamping or slippage of the flat wire during twisting due to excessive clamping, thus affecting the forming quality of the twisted structure.

[0050] In this embodiment, as Figure 3 As shown, both the first fastener 34 and the second fastener 35 have triangular cross-sectional shapes. Specifically, both the first fastener 34 and the second fastener 35 have triangular cross-sectional shapes. The end of the first fastener 34 facing the second fastener 35 has an integrally formed first inclined surface 341, which is one of the hypotenuses of the triangular cross-section. The end of the second fastener 35 facing the first fastener 34 has a corresponding second inclined surface 351, which is also a corresponding hypotenuse of the triangular cross-section. The inclination angles and contour curvatures of the first inclined surface 341 and the second inclined surface 351 are matched to form a wedge-shaped fit structure that is tightly fitted and evenly stressed. In use, a slot is formed between the first inclined surface 341 and the second inclined surface 351, facing the twisting station 33. This slot allows the flat wire in its initial state to extend into the twisting station 33, ensuring the subsequent clamping and twisting of the flat wire.

[0051] Based on the above embodiments, the present invention also discloses a stator winding device, such as... Figure 1 and Figure 6As shown, the device includes a frame 40, which is sequentially equipped with a feeding mechanism 50, a winding mechanism 60, a clamping mechanism 70, a wire cutting mechanism 80, and a twisting mechanism as described in any of the preceding embodiments along the z-axis. A second slide rail 41 is provided on the frame 40 along the z-axis. The fixed base 10 is slidably mounted on the second slide rail 41. The clamping mechanism 70 is used to hold the stator core. The clamping mechanism 70 includes a positioning member 71 and a second driving member. The positioning member 71 is rotatably mounted on the frame 40 and is used to engage the stator core. The second driving member is fixed to the frame 40. The output shaft of the second driving member is connected to the positioning member 71 for driving the positioning member 71 to rotate, thereby rotating the stator core.

[0052] Specifically, the frame 40 is arranged along the z-axis with a feeding mechanism 50, a winding mechanism 60, a clamping mechanism 70, a wire cutting mechanism 80, and a twisting mechanism as described above. Each mechanism is arranged linearly and regularly along the z-axis. Their positions are precisely matched with the process flow of stator winding, ensuring smooth connection between processes, greatly shortening process changeover time, and improving overall processing efficiency.

[0053] A second slide rail 41 extends along the z-axis on the frame 40. The second slide rail 41 is slidably engaged with the fixing seat 10 of the twisting mechanism, meaning the fixing seat 10 of the twisting mechanism is slidably mounted on the second slide rail 41, allowing the fixing seat 10 to slide along the frame 40 in the z-axis direction, thereby driving the twisting assembly 30 to slide in the z-axis direction. A clamping mechanism 70 is disposed between the winding mechanism 60 and the wire cutting mechanism 80. The structure of the clamping mechanism 70 is adapted to the outer contour of the stator core, used to achieve stable placement and positioning of the stator core.

[0054] In actual use, each mechanism is initially in a preset state. The positioning part 71 of the clamping mechanism 70 remains stationary, the fixed seat 10 of the twisting mechanism is located at the preset position of the second slide rail 41, the first slide 20 is located at the initial position of the first slide rail 11, and the first clamping part 31 and the second clamping part 32 are separated. After the operation starts, the feeding mechanism 50 first transports the flat wire to the winding mechanism 60 to complete the feeding of the flat wire. Then the winding mechanism 60 is started, so that the winding mechanism 60 reciprocates along the three directions of x-axis, y-axis and z-axis, and cooperates with the clamping mechanism 70 to complete the winding operation of the stator core clamped and fixed on the clamping mechanism 70. After the winding process is completed, the wire cutting mechanism 80 cuts the flat wire. During this process, the length of the cut flat wire end can be ensured to meet the preset processing standard through program design. After the wire cutting process is completed, the twisting mechanism twists the flat wire end to the preset forming state, and finally completes the winding processing of a single stator core. Then each mechanism is reset and enters the next round of operation cycle. In this process, the pre-set procedure is based on existing technology, which will not be elaborated here.

[0055] In this embodiment, as Figure 1 and Figure 4 As shown, the clamping mechanism 70 includes a positioning component 71 and a second driving component. The positioning component 71 is rotatably mounted on the frame 40 and has a snap-fit ​​structure adapted to the stator core. The dimensions of this snap-fit ​​structure precisely match the inner hole or outer edge dimensions of the stator core, enabling rapid snap-fit ​​positioning of the stator core while providing good positioning stability to prevent loosening or displacement of the stator core during winding and twisting operations. The second driving component is fixed to the frame 40, and its output shaft is connected to the positioning component 71. The second driving component drives the positioning component 71 to rotate uniformly around its own axis, thereby synchronously rotating the stator core snapped onto the positioning component 71. This allows the winding mechanism 60 to accurately complete the winding operation along the circumference of the stator core, ensuring uniform winding density, regular winding trajectory, and improving the processing quality of the stator winding.

[0056] In actual use, the positioning component 71 clamps and fixes the stator core. After the second driving component is activated, it drives the positioning component 71 to rotate, thereby causing the stator core to rotate at a uniform speed. At the same time, the winding mechanism 60 is activated to wind the wire onto the inner surface of the rotating stator core. After the winding is completed, the wire cutting mechanism 80 cuts the end of the flat wire according to the preset length to ensure that the length of the flat wire end meets the preset standard. After the wire is cut, the wire twisting mechanism is adjusted to the position corresponding to the end of the flat wire, so that the end of the flat wire extends into the twisting station 33 through the slot between the first fastener 34 and the second fastener 35. Finally, the first clamping component 31 and the second clamping component 32 move towards each other, and with the pressing and positioning of the first inclined surface 341 and the second inclined surface 351, the loose flat wire is tightened and firmly clamped, and the end of the flat wire is twisted to form a twisted structure.

[0057] In this embodiment, as Figure 4 As shown, the clamping mechanism 70 further includes a first limiting block 72 and a second limiting block 73; the first limiting block 72 is disposed on the top of the positioning member 71; the second limiting block 73 is connected to the first limiting block 72; a limiting groove is formed between the first limiting block 72 and the second limiting block 73; the limiting groove is used to limit the end of the flat wire. Specifically, the first limiting block 72 and the second limiting block 73 cooperate to clamp and limit the end of the flat wire, providing a precise positioning reference for the subsequent twisting operation of the twisting mechanism, and further ensuring the consistency and accuracy of the flat wire twisting. The first limiting block 72 is fixedly assembled on the top of the positioning member 71, and the second limiting block 73 is fixedly connected to the first limiting block 72. The relative positions of the two can be adaptively adjusted according to the specifications and dimensions of the flat wire to meet the limiting requirements of flat wires of different widths and thicknesses.

[0058] The first limiting block 72 and the second limiting block 73 form a limiting groove. After the winding mechanism 60 completes one turn of winding, the first limiting block 72 and the second limiting block 73 clamp and limit the end of the flat wire, constraining the displacement of the flat wire end. After the stator core completes all winding processes, the ends of multiple flat wires are neatly accommodated inside the limiting groove, forming a flat and orderly arrangement. Then, the twisting mechanism starts and connects to the flat wire ends at the limiting groove, twisting the multiple flat wires after limiting them to form a preset twisted structure. Through the limiting action of the first limiting block 72 and the second limiting block 73, abnormal situations such as displacement or misalignment of the flat wire ends before twisting can be effectively avoided, ensuring that the twisting mechanism can achieve synchronous and uniform twisting of multiple flat wires, further improving the twisting forming quality and processing efficiency.

[0059] In this embodiment, as Figure 1 and Figure 6As shown, the feeding mechanism 50 is located at the end of the frame 40; the feeding mechanism 50 is provided with a plurality of winding posts 51; the plurality of winding posts 51 are used to convey flat wire. In this embodiment, the feeding mechanism 50 is fixedly assembled at the end position of the frame 40. The feeding mechanism 50 is provided with a plurality of winding posts 51. The function of the plurality of winding posts 51 is to realize the orderly conveying and guiding of flat wire. The flat wire is pre-wound on the winding posts 51 to form a regular state ready for conveying. During operation, with the traction action of the winding mechanism 60, the winding posts 51 release the flat wire synchronously. Through their own guiding action, the flat wire is accurately and smoothly conveyed to the working end of the winding mechanism 60, ensuring that no abnormalities such as entanglement, deviation, or jamming occur during the flat wire conveying process, and realizing the continuous and stable supply of flat wire. Meanwhile, the coordinated arrangement of multiple winding posts 51 can adapt to the synchronous conveying requirements of multiple flat wires, and form a precise match with the multi-flat wire collaborative operation mode of subsequent winding and twisting processes, further improving the overall processing efficiency and operation coordination of the stator winding equipment.

[0060] In one embodiment, the frame 40 is provided with a third slide rail 42 along the z-axis; the winding mechanism 60 includes: a third driving member, a second slide block 62, a moving module 63, and a winding member 64; the third driving member is disposed on the frame 40; the second slide block 62 is drivenly connected to the third driving member and is slidably disposed on the third slide rail 42; the second slide block 62 is provided with a fourth slide rail 621 along the x-axis; the second slide block 62 is provided with a fourth driving member; the moving module 63 is slidably disposed on... The second slide block 62 is connected to the fourth driving member; the moving module 63 is provided with a fifth slide rail 631 along the y-axis; one end of the winding member 64 is movably mounted on the fifth slide rail 631, and the other end extends to the top of the clamping mechanism 70; the end of the winding member 64 near the clamping mechanism 70 is provided with a winding head 641; wherein, the winding head 641 is rotatably mounted on the winding member 64; the winding head 641 is provided with a wire passage hole; the wire passage hole is used for flat wire to pass through.

[0061] In use, the frame 40 is further provided with a third slide rail 42 along the z-axis, the second slide block 62 is provided with a fourth slide rail 621 along the x-axis, and the moving module 63 is provided with a fifth slide rail 631 along the y-axis. In this way, the winding mechanism 60, which is used for stator winding, can achieve precise displacement adjustment in the three directions of x-axis, y-axis and z-axis, ensuring that the flat wire can be wound evenly along the preset trajectory of the stator core.

[0062] Specifically, the output end of the third driving component is connected to the second slide block 62, driving the second slide block 62 to slide along the third slide rail 42; the output end of the fourth driving component is connected to the moving module 63, driving the moving module 63 to slide along the fourth slide rail 621; the moving module 63 is provided with a fifth slide rail 631 extending along the y-axis direction, the extension direction of the fifth slide rail 631 being perpendicular to both the fourth slide rail 621 and the third slide rail 42, forming a three-dimensional spatial guide structure, providing precise support and guidance for the lifting and lowering movement of the winding component 64 along the y-axis direction. The moving module 63 is provided with a seventh driving component, which is connected to the winding component 64. One end of the winding component 64 is movably mounted on the fifth slide rail 631 to achieve reciprocating lifting and lowering of the winding component 64 along the y-axis, thereby adjusting the distance between the winding head 641 and the stator core on the clamping mechanism 70 to adapt to the winding height requirements of stator cores of different specifications; the other end of the winding component 64 is equipped with a winding head 641, which is rotatably connected to the end of the winding component 64. The winding head 641 has a wire-passing hole that passes through both ends of the winding head 641. The hole diameter is precisely matched with the cross-sectional size of the flat wire to avoid scratches or damage to the surface of the flat wire, while ensuring that the flat wire can pass smoothly through the wire-passing hole to achieve precise traction and winding of the flat wire.

[0063] In actual operation, the flat wire passes through the wire hole of the winding head 641 after passing through multiple winding posts 51. The winding mechanism 60, through the coordinated drive of the third and fourth driving components, drives the winding component 64 to complete the position adjustment in the z-axis and x-axis directions. The seventh driving component drives the winding component 64 to rise and fall along the fifth slide rail 631 to achieve height adjustment in the y-axis direction, thereby achieving precise alignment between the winding head 641 and the stator core winding position. Subsequently, while the second driving component drives the stator core to rotate, the winding head 641 rotates synchronously, pulling the flat wire to achieve uniform winding along the circumference of the stator core. The wire hole always plays a guiding and limiting role for the flat wire, ensuring that the flat wire does not deviate or entangle during the winding process, ensuring uniform winding density and regular winding trajectory, and providing a reliable guarantee for the smooth progress of subsequent wire cutting and twisting processes.

[0064] In this embodiment, a fifth driving member is provided on the top of the winding member 64; the fifth driving member is connected to the winding head 641 in a transmission manner and is used to drive the winding head 641 to rotate.

[0065] In one implementation, such as Figure 5As shown, the wire cutting mechanism 80 includes a sixth driving member, a first shear 82, and a second shear 83; the sixth driving member is mounted on the frame 40; the first shear 82 and the second shear 83 are both connected to the sixth driving member in a transmission manner; the first shear 82 and the second shear 83 are arranged opposite to each other; the sixth driving member is used to drive the first shear 82 and the second shear 83 to move along the y-axis direction of the frame 40 and cut the flat wire.

[0066] In one embodiment, the sixth driving component is fixedly mounted on the frame 40, with its output direction aligned with the y-axis direction of the frame 40, and is connected in a transmission manner to the first shears 82 and the second shears 83. The first shears 82 and the second shears 83 are arranged symmetrically, and their assembly positions precisely correspond to the arrangement positions of the flat wire ends on the clamping mechanism 70, ensuring accurate docking of the flat wire after winding. In actual use, when the winding mechanism 60 completes the winding operation of the stator core, the sixth driving component is activated, driving the first shears 82 and the second shears 83 to move synchronously along the y-axis of the frame 40. After clamping the end of the flat wire, the sixth driving component continues to drive the first shears 82 and the second shears 83 to further come into contact with each other. Using the shearing force of their blades, the flat wire is cut off, ensuring that the length of the cut flat wire end meets the preset standard. After the cutting is completed, the sixth driving component reverses the drive, causing the first shears 82 and the second shears 83 to move in the opposite direction along the y-axis, resetting to the initial position, releasing the constraint on the cut flat wire end, reserving sufficient working space for the subsequent twisting operation of the twisting mechanism, and ensuring a smooth connection between the wire cutting process and the twisting process.

[0067] In one implementation, such as Figure 1 and Figure 6 As shown, the winding mechanism 60, clamping mechanism 70, wire cutting mechanism 80, and twisting mechanism of the stator winding equipment work together in a coordinated manner, performing operations step by step according to a preset procedure to ensure the neat arrangement and precise twisting of multiple flat wires. Specifically, in the actual production process, after the winding mechanism 60 completes each flat wire winding action, the third driving component continuously drives the second slide block 62 to slide horizontally along the third slide rail 42 towards the twisting mechanism, causing the winding component 64 to move synchronously towards the twisting mechanism. During this process, the winding head 641 at the end of the winding component 64 synchronously pulls the flat wire to extend until the end of the flat wire is pulled to the outside of the first limiting block 72 and located directly above the wire cutting mechanism 80, ensuring that the end of the flat wire corresponds precisely to the cutting position of the wire cutting mechanism 80.

[0068] After the flat wire end is positioned, the first limiting block 72 and the second limiting block 73 firmly fix the flat wire end in the limiting groove. Through the constraint of the limiting groove, the flat wire end is ensured to maintain a neat and even arrangement, preventing it from shifting or misaligning. Subsequently, the twisting mechanism rotates circumferentially, driving the first clamping member 31 and the second clamping member 32 to rotate synchronously until they reach a horizontal position. At the same time, the twisting mechanism rises and falls until the ends of the first clamping member 31 and the second clamping member 32 are at the same horizontal height as the flat wire end in the limiting groove. The first clamping member 31 and the second clamping member 32 move towards each other, clamping the flat wire end to achieve temporary fixation and prevent the flat wire from shifting during the cutting process. Next, the sixth driving member drives the first shears 82 and the second shears 83 to cut the flat wire. After cutting, the cutting mechanism 80 and the twisting mechanism are reset, waiting for the next work cycle. The above process is repeated multiple times. Each cycle completes the winding, pulling, limiting, clamping and cutting of one flat wire until multiple flat wires are neatly arranged inside the limiting groove formed by the first limiting block 72 and the second limiting block 73, which meets the quantity and arrangement requirements of the twisting operation.

[0069] Once a preset number of flat wires have accumulated in the limiting groove, the twisting mechanism rotates circumferentially, causing the first clamping member 31 and the second clamping member 32 to rotate synchronously until they switch from a horizontal to a vertical state. Simultaneously, the twisting mechanism adjusts its height again, aligning the groove formed between the first fastener 34 and the second fastener 35 with the multiple flat wires in the limiting groove. Then, the twisting mechanism slides towards the clamping mechanism 70 until the multiple flat wires in the limiting groove pass through the groove between the first fastener 34 and the second fastener 35 and are placed at the twisting station 33. Next, the first clamping member 31 and the second clamping member 32 move towards each other, causing the first fastener 34 and the second fastener 35 to move closer together, gradually bringing the first inclined surface 341 and the second inclined surface 351 into close contact. Utilizing their wedge-shaped fit, the multiple flat wires are compressed and positioned, tightening and organizing the loosely arranged flat wires. After the clamping and positioning are completed, the twisting assembly 30 rotates synchronously, causing the multiple flat wires being clamped to wrap around each other synchronously, twisting the multiple flat wires into a preset braided structure, completing the twisting operation of multiple flat wires in a single operation. Then, each mechanism resets and enters the next complete operation cycle.

[0070] In summary, this invention discloses a wire twisting mechanism and a stator winding device. The wire twisting mechanism includes a fixed base, a first slide block, and a wire twisting assembly. The fixed base is provided with a first slide rail along the x-axis. The first slide block is slidably mounted on the first slide rail. A first driving member is provided on the first slide block. The wire twisting assembly is located on the first slide block and is drively connected to the first driving member. The wire twisting assembly includes a first clamping member and a second clamping member disposed opposite to each other. A wire twisting station is formed between the first clamping member and the second clamping member. The first clamping member and the second clamping member move towards each other to clamp flat wires. The first driving member drives the wire twisting assembly to rotate, thereby winding multiple flat wires into a twisted structure. In use, the first driving member drives the first slide block to slide to the ends of multiple flat wires, placing the multiple flat wires in the wire twisting station. Subsequently, the first clamping member and the second clamping member clamp the ends of the flat wires together and rotate synchronously, causing the multiple flat wires to intertwine and form a twisted structure. This invention effectively replaces traditional manual operation by automating the wire twisting process, solving the problems of low efficiency and unstable quality associated with manual wire twisting.
