Description

Technical Field

[0001] This utility model belongs to the field of automatic winding technology of stepper motor coils without PCB board, and specifically relates to a multi-wire cross-winding device with adjustable wire nozzle position. Background Technology

[0002] In modern industrial production, coil manufacturing is a core component of electronic components such as motors, transformers, and inductors. Traditional winding machines have significant limitations in design, mainly manifested in: insufficient wire routing capacity, with most machines only supporting single or double-wire winding, making it difficult to meet the needs of complex coil structures. For example, some high-precision motors or transformers require processing four cables simultaneously, while traditional machines require multiple adjustments to complete this task, resulting in low efficiency; loose coil structure: due to the fixed pin spacing, the coil cannot fit tightly after winding, leading to an excessive coil volume and the generation of parasitic capacitance (similar to excess "interference" between wires). This phenomenon reduces the electrical performance of the coil and may even cause leakage inductance (similar to "leakage current" in circuits); poor process adaptability: the pin positions and wire routing paths of traditional machines are fixed, making it impossible to flexibly adapt to different frame structures (such as multi-pin or irregularly shaped frames). This limits its application in diverse industrial scenarios, such as complex processes that require switching between forward and reverse winding; frequent quality defects: during the winding process, the cable is prone to bending, overlapping or loosening, resulting in excessive coil temperature rise, which may cause equipment failure after long-term use; high dependence on manual labor: traditional equipment requires frequent manual adjustment of pin spacing or switching of process modes, which is not only time-consuming and labor-intensive, but also prone to affecting product quality due to operational errors.

[0003] The aforementioned problems severely restrict the efficiency and quality of coil manufacturing. Therefore, there is an urgent need for a new type of winding device that, through optimized structural design and automated control, can overcome existing technological bottlenecks and achieve a highly efficient and precise multi-wire parallel winding process. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-wire parallel winding crossover device with adjustable wire nozzle position. Through the coordinated drive of multiple cylinders and multiple guide rails, it realizes the synchronous start and take-up operation of four wires parallel winding. By switching the wire nozzle position, it can flexibly adapt to various skeleton coil processes (forward winding / reverse winding), thereby improving winding efficiency and coil quality, and solving the problems of insufficient wire laying capacity, loose structure and poor process adaptability of traditional equipment.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a multi-wire parallel winding and crossing device with adjustable wire nozzle position, comprising: a fixing plate, the fixing plate including a first fixing plate and a second fixing plate, the second fixing plate being connected below the first fixing plate, and a plurality of first guide rails being spaced apart between the first fixing plate and the second fixing plate;

[0006] A wire nozzle assembly, comprising multiple front and rear wire nozzles and multiple left and right wire nozzles, wherein the front and rear wire nozzles are fixed to a first fixed plate by front and rear wire nozzle fixing blocks, and the left and right wire nozzles are fixed to the sides of left and right movable plates by left and right wire nozzle fixing blocks, and the left and right movable plates are fixed below a second fixed plate, and multiple second guide rails are spaced apart between the second fixed plate and the left and right movable plates.

The fixed plate provides a supporting foundation for the independent movement of the front and rear wire nozzles and the left and right wire nozzles. The left and right wire nozzles can move with the left and right movable plates, thereby dynamically adjusting the spacing between the front and rear wire nozzles and the left and right wire nozzles. By utilizing the positions of the left and right wire nozzles and the front and rear wire nozzles at different gaps, different starting and ending positions can be set for different coils on the same frame or different parts of the same coil to achieve multi-starting / multi-ending point winding. This not only allows for flexible selection of the winding direction but also precise control of the starting and ending points, supports complex motion modes, and can also achieve synchronous winding processes, thus meeting the diverse production needs of different motors, transformers, and other electronic components. This enables the forward and reverse winding of various coils; simultaneously, this structure also uses multi-cylinder drive to achieve synchronous winding, enabling various frame coil processes.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4This utility model provides an adjustable multi-wire parallel winding and crossing device, including: a fixing plate 100, a wire nozzle assembly 200, and a cylinder assembly 300. The fixing plate 100 includes a first fixing plate 110 and a second fixing plate 120. The second fixing plate 120 is connected to the lower part of the first fixing plate 110. A plurality of first guide rails 130 are spaced apart between the first fixing plate 110 and the second fixing plate 120. The wire nozzle assembly 200 includes a plurality of front and rear wire nozzles 210 and a plurality of left and right wire nozzles 220. The front and rear wire nozzles 210 are fixed to the first fixing plate 110 by front and rear wire nozzle fixing blocks 211. The left and right wire nozzles 220 are fixed to the sides of left and right movable plates 140 by left and right wire nozzle fixing blocks 221. The left and right movable plates 140 are fixed to the lower part of the second fixing plate 120. Multiple second guide rails 150 are spaced apart between the second fixed plate 120 and the left and right movable plates 140; the cylinder assembly 300 includes left and right limiting cylinders 310, front and rear limiting cylinders 320 and gap adjusting cylinders 330. The left and right limiting cylinders 310 are fixed on both sides of the fixed plate 100 and below the second fixed plate 120. The front and rear limiting cylinders 320 are fixed on both ends of the first fixed plate 110. The gap adjusting cylinder 330 is fixed on one end of the left and right movable plates 140. A third cylinder connector 331 is provided between the gap adjusting cylinder 330 and the left and right movable plates 140. The left and right movable plates 140 can move left and right under the action of the gap adjusting cylinder 330 to drive the left and right wire nozzles 220 to move, so that the distance between the front and rear wire nozzles 210 and the left and right wire nozzles 220 changes. The gap between the front and rear thread nozzles 210 and the left and right thread nozzles 220 proposed in this application can be varied. For example, there are four different gaps between the front and rear thread nozzles 210 and the left and right thread nozzles 220, so that the thread nozzle assembly 200 has four positions: A, B, C, and D. When it is necessary to switch the thread nozzle position from A to B, the left limiting cylinder 311 is activated, pushing the left and right movable plates 140 to move to the left, so that the left and right thread nozzles 220 are aligned with the left needle of the bobbin. When it is necessary to switch from C to D, the right limiting cylinder 312 is activated, pushing the left and right movable plates 140 to move to the right, so that the left and right thread nozzles 220 are aligned with the right needle of the bobbin. During the winding process, the front and rear limiting cylinders 320 adjust the longitudinal position of the front and rear thread nozzles 210 through push and pull actions to adapt to bobbins of different lengths. For example, if the bobbin has a double-groove structure, the front limiting cylinder 321 pushes the first fixing plate 110 forward, causing the front and rear wire nozzles 210 to move forward and widen the distance between them and the left and right wire nozzles 220. If the bobbin has a single-groove structure, the rear limiting cylinder 322 pulls the first fixing plate 110 backward, causing the front and rear wire nozzles 210 to move backward and narrow the distance between them and the left and right wire nozzles 220. When winding a multi-pin bobbin, the gap adjusting cylinder 330 finely adjusts the position of the left and right movable plates 140 to ensure that the left and right wire nozzles 220 are precisely aligned with different pins, preventing cable misalignment or overlap.

[0024] Furthermore, the parallel winding and crossing device of this application can also switch between clockwise and counterclockwise winding of the coil, and can also achieve bidirectional winding and reciprocating winding, forming a back-and-forth wire-running effect, which can manufacture coils of specific shapes, such as trapezoidal windings or coils requiring tight filling. The control system commands the front and rear cylinders of the wire nozzle to repeatedly move in two positions, realizing the back-and-forth reciprocating motion of the wire nozzle. At the same time, the left and right limit cylinders 310 can be locked in a certain position, or also participate in fine adjustment, and the entire wire-starting and winding process remains synchronous. It can also realize multi-starting point and multi-ending point winding, for example, the first coil starts from position B and is wound at position B; the second coil starts from position C and is wound at position D. The cylinder system precisely moves the wire nozzle to the designated starting and ending positions according to the program, and synchronously completes the wire-starting and winding operations.

[0025] The technical solution proposed in this utility model achieves high precision, high stability, and process flexibility in the multi-wire parallel winding process by setting up a coordinated structure of a fixed plate 100, a wire nozzle assembly 200, and a cylinder assembly 300. The fixed plate 100 provides a supporting foundation for the independent movement of the front and rear wire nozzles 210 and the left and right wire nozzles 220. The left and right wire nozzles 220 can move with the left and right movable plates 140, thereby dynamically adjusting the spacing between the front and rear wire nozzles 210 and the left and right wire nozzles 220. By utilizing the positions of the left and right wire nozzles 220 and the front and rear wire nozzles 210 at different gaps, different starting and ending positions can be set for different coils on the same frame or different parts of the same coil to achieve multi-starting point / multi-ending point winding. It can not only flexibly select the winding direction but also accurately control the starting and ending points, and support complex motion modes. It can also realize the synchronization of the starting and winding processes, thereby meeting the diversified production needs of different motors, transformers, and other electronic components.

[0026] Furthermore, in the parallel winding crossover device proposed in this application, the top ends of multiple front and rear wire nozzle fixing blocks 211 are connected to the first fixing plate 110, and the multiple front and rear wire nozzle fixing blocks 211 are evenly arranged in a suspended manner. This "suspended" design has multiple technical advantages. First, the suspended structure positions the front and rear wire nozzles 210 below the first fixing plate 110, lowering the center of gravity and enhancing the overall structure's vibration resistance. During high-speed winding, the equipment generates high-frequency vibrations; if the wire nozzles are not securely fixed, it can easily lead to cable shifting or loosening. The suspended fixing effectively reduces the impact of vibration on the wire nozzle position by concentrating the weight of the wire nozzles below, ensuring the stability of the winding path. Simultaneously, the evenly arranged front and rear wire nozzle fixing blocks 211 ensure the symmetry and consistency of the cable distribution. During multi-wire parallel winding, four cables need to be wound simultaneously; if the spacing between the wire nozzles is uneven, it will lead to inconsistent cable tension, resulting in localized over-tightness or under-tightness. The uniformly arranged design ensures that the starting position and trajectory of each cable are completely symmetrical, thus achieving tension balance. For example, when winding high-precision transformer coils, even slight differences in cable tension can affect the coil's electrical performance. This solution, through the uniformly arranged wire nozzle fixing blocks 211, ensures that the four cables are subjected to uniform force during winding, avoiding leakage inductance or temperature rise problems caused by uneven tension. Furthermore, the suspended design facilitates maintenance and replacement. Wire nozzles are consumable parts and may wear or become clogged after long-term use. Traditional fixing methods require disassembling the entire fixing plate to replace the wire nozzles, which is time-consuming and labor-intensive. However, the suspended structure of this solution places the wire nozzles on the outside, allowing operators to directly remove the front and rear wire nozzle fixing blocks 211 from below without moving the upper structure, greatly simplifying the maintenance process. Furthermore, the lower end face of the first fixed plate 110 is provided with a first opening groove 111, and the first guide rail 130 can be inserted into the first slider 112 to drive the first slider 112 to be inserted into the first opening groove 111. There are six first guide rails 130, and the six first guide rails 130 are evenly fixed in the first fixed plate 110. The design of the first opening groove 111 allows the first guide rail 130 to be embedded in the first fixed plate 110, forming a closed guide structure. Compared with the traditional external guide rail, this built-in design significantly improves the bending resistance and torsional stiffness of the guide rail. During high-speed operation, external guide rails are prone to bending due to vibration or external force, causing the position of the wire nozzle to deviate. However, the first guide rail 130 of this solution is wrapped by the first fixed plate 110 and constrained by the upper and lower sides, effectively suppressing bending deformation and ensuring that the front and rear wire nozzles 210 always maintain a straight trajectory when moving longitudinally. Of course, this application does not limit the specific number of the first guide rails 130. Preferably, there are six first guide rails 130. The multi-rail design not only distributes the motion load but also improves the redundancy of the system. If a single guide rail wears out or fails, the remaining guide rails can still maintain basic guiding functions, preventing sudden equipment failure.The insertion structure between the first slider 112 and the first opening slot 111 further enhances the guiding accuracy. The slider has an internal groove that matches the first guide rail 130. After the guide rail is inserted, a tight fit is formed, restricting the slider's freedom in the lateral and vertical directions, allowing it to slide only along the guide rail axis. This design effectively prevents the slider from wobbling or tilting during movement, ensuring a highly stable movement path for the front and rear nozzles 210.

[0027] Furthermore, the lower end face of the second fixed plate 120 is provided with an opening 121, and the second guide rail 150 can be fixed inside the second slider 122 to drive the second slider 122 to connect with the opening 121. There are eight second guide rails 150, which are evenly fixed inside the second fixed plate 120. The upper end face of the second guide rail 150 is provided with a second opening groove 123, and the first guide rail 130 is snapped into the second opening groove 123. The opening 121 design allows the second slider 122 to be directly connected to the second fixed plate 120 to form an integrated motion frame. The second guide rail 150 is fixed inside the second slider 122 and then connected to the second fixed plate 120 through the opening 121. This structure ensures a rigid connection between the guide rail and the fixed plate, avoiding guiding errors caused by loose connections. The eight second guide rails 150 are evenly fixed inside the second fixed plate 120, forming a dense guiding network. The multi-guide rail design not only improves the load-bearing capacity of the system but also enhances its vibration resistance. When the left and right movable plates 140 reciprocate rapidly, the equipment will generate lateral vibration. If the number of guide rails is insufficient, the vibration is easily transmitted to the wire nozzles, affecting the winding quality. The snap-fit ​​structure of the upper and lower guide rails not only transmits the longitudinal load but also restricts the relative displacement between the two fixed plates, ensuring that the front and rear wire nozzles 210 and the left and right wire nozzles 220 remain synchronized during movement. For example, if the upper and lower fixed plates slide relative to each other when switching wire nozzle positions, it will cause the wire nozzle spacing to become inaccurate. Furthermore, the parallel winding cross device proposed in this application also includes a cutter assembly 400. The wire nozzle assembly 200 is located on the first side of the left and right movable plates 140, and the cutter assembly 400 is located on the second side of the left and right movable plates 140. The cutter assembly 400 includes a four-wire cutter 410, a cutter fixing seat 420, and a cutter fixing pin 430. The cutter holder 420 has a slot 422, into which the second side of the left and right movable plates 140 can be engaged. The cutter holder 420 also has a protrusion 421, to which the four-wire cutter 410 is fixed by a cutter fixing pin 430. Vertically, the four-wire cutter 410 and the wire nozzle assembly 200 are at the same height. By adding the cutter assembly 400, automatic cutting of the cable after winding is achieved, improving the automation level and production efficiency of the equipment. Specifically, the wire nozzle assembly 200 is located on the first side of the left and right movable plates 140, and the cutter assembly 400 is located on the second side, forming a symmetrical layout. This layout ensures that the wire nozzle and the cutter remain synchronized during movement, avoiding cutting failures due to positional deviations. For example, when the left and right movable plates 140 move laterally, the cutter assembly 400 moves synchronously with them, ensuring that the cutting position is always aligned with the wire nozzle, allowing the cutter to accurately cut the cable regardless of the nozzle's position. The four-wire cutter 410 can cut four cables simultaneously, eliminating the need to cut them one by one and significantly reducing cutting time. Furthermore, by defining the structure of the cutter holder 420 and the installation method of the four-wire cutter 410, the vertical height of the cutter and the wire nozzle is ensured to be consistent, achieving precise cutting.Specifically, the cutter mounting base 420 is provided with a slot 422, and the second side of the left and right movable plates 140 is engaged in the slot 422 to form a stable mechanical connection. This engagement structure not only simplifies the installation process, but also ensures the precise relative position of the cutter assembly 400 and the left and right movable plates 140.

[0028] Furthermore, the front and rear limiting cylinders 320 are connected to the first fixed plate 110 via the first cylinder connector 323. The front and rear limiting cylinders 320 include a front limiting cylinder 321 and a rear limiting cylinder 322, which are respectively fixed to the front and rear ends of the first fixed plate 110. The left and right limiting cylinders 310 are connected to the left and right movable plates 140 via limiting blocks 313. The left and right limiting cylinders 310 include a left limiting cylinder 311 and a right limiting cylinder 312, which are respectively located at the ends of the left and right movable plates 140. This application achieves precise control and stable adjustment of the positions of the front and rear nozzles 210 by limiting the connection method and layout of the front and rear limiting cylinders 320. Specifically, the front and rear limiting cylinders 320 are connected to the first fixed plate 110 via the first cylinder connector 323, forming a reliable mechanical transmission. The first cylinder connector 323, acting as an intermediate connector, not only transmits the cylinder's thrust but also compensates for installation errors, ensuring alignment between the cylinder piston rod and the first fixed plate 110. For example, if the connector lacks rigidity during cylinder operation, eccentric forces can easily occur, causing the first fixed plate 110 to tilt. The front and rear limit cylinders 320 include a front limit cylinder 321 and a rear limit cylinder 322, respectively fixed to the front and rear ends of the first fixed plate 110. This symmetrical layout ensures balanced force on the first fixed plate 110 during longitudinal movement, preventing twisting or vibration caused by unilateral force. For example, when adjusting the position of the front and rear wire nozzles, the front limit cylinder 321 pushes the first fixed plate 110 forward, while the rear limit cylinder 322 provides counter-support, forming a stable push-pull structure. This dual-cylinder drive mechanism not only improves the adjustment speed but also enhances the accuracy of position control. The control system can independently adjust the stroke of the front and rear limit cylinders 320, achieving micron-level position adjustment to meet high-precision winding requirements. This application achieves precise limiting and stable driving of the lateral movement of the left and right movable plates 140 by defining the connection method and layout of the left and right limiting cylinders 310. Specifically, the left and right limiting cylinders 310 are connected to the left and right movable plates 140 through limiting blocks 313, forming a rigid transmission structure. The left and right limiting cylinders 310 include a left limiting cylinder 311 and a right limiting cylinder 312, which are located at the two ends of the left and right movable plates 140, respectively. This symmetrical layout ensures that the left and right movable plates 140 are subjected to balanced forces during lateral movement, avoiding deflection or jamming caused by unilateral force. For example, when driving the left and right cable nozzles 220 to move to the left, the left limiting cylinder 311 provides thrust, and the right limiting cylinder 312 provides reverse support, forming a stable push-pull structure.

[0029] Furthermore, a ceramic eye fixing plate 500 is provided above the first fixing plate 110, and the ceramic eye fixing plate 500 is connected to the first fixing plate 110 by screws. The ceramic eye fixing plate 500 has multiple ceramic eye holes, through which the cable passes into the front and rear cable nozzles 210. The ceramic eye holes serve as guide channels for the cable, restricting the cable's freedom of movement before entering the cable nozzles and preventing it from shaking or shifting. The ceramic eye fixing plate 500 is connected to the first fixing plate 110 by screws, forming a detachable fixing method. This design facilitates maintenance and replacement. As a consumable part, the ceramic eye holes may wear or become clogged after long-term use. Operators can directly remove the screws and remove the ceramic eye fixing plate 500 for cleaning or replacement without disassembling the entire fixing plate 100. Furthermore, a needle bar thickening block 600 is provided on one side of the left and right limit cylinders 310. The needle bar thickening block 600, as an additional structure, is installed at the end of the piston rod of the left and right limit cylinders 310 and connected to the limit block 313. During frequent reciprocating motion of the cylinder, the connection between the piston rod and the limit block 313 is subjected to huge alternating loads, which can easily lead to wear or fatigue fracture. The thickened needle rod block 600 significantly improves the tensile strength and bending stiffness of this part by increasing the cross-sectional area of ​​the piston rod end.
