Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a wire position identification device. Background Technology

[0002] Magnetic ring winding is a core process in the production of network transformers. Multiple colors of wire need to be wound on a single magnetic ring, and the vertical positions of different colored wires (such as colors A and B) are strictly regulated. Subsequent splitting and stranding processes must ensure that the positions of the A and B colored wires on all magnetic rings are consistent.

[0003] However, in current production, due to factors such as handling and transferring after winding, the vertical positions of A and B color wires are prone to random deviations. Existing network transformer production equipment can only perform basic operations such as winding and conveying, and cannot identify the vertical position of the wires. Some companies still need to manually inspect and adjust, which is not only costly in terms of labor and inaccurate, but also difficult to adapt to automated production cycles, easily leading to product quality problems and low efficiency.

[0004] In summary, there is a gap in the technology for identifying the position of the magnetic ring wire after winding, and existing equipment cannot meet the process requirements. Developing relevant automatic identification solutions has become an urgent problem to be solved. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a wire position identification device.

[0006] A wire position identification device designed for this purpose includes a machine base, a shooting module, a first clamping element, and a second clamping element;

[0007] The shooting module is positioned on either the left or right side of the first clamping element;

[0008] When the shooting module takes a picture, the first clamping element and the second clamping element are arranged at a distance from each other and clamp the wire respectively, and the shooting module takes a picture of the wire between the first clamping element and the second clamping element.

[0009] Preferably, the machine tool is provided with a moving module, and the second clamping element is connected to the moving module. The moving module is used to drive the second clamping element to move relative to the machine tool.

[0010] Preferably, the device further includes a third clamping element, which is spaced apart from the first clamping element.

[0011] Preferably, the machine tool is provided with a linear module, and the first clamping element and the third clamping element are movable back and forth relative to the machine tool;

[0012] The linear module is used to drive the first clamping element and the third clamping element to move back and forth relative to the machine tool.

[0013] Preferably, the shooting module includes at least a camera and a lens mounted on the camera.

[0014] Preferably, the shooting module also includes a fill light.

[0015] Preferably, the fill light has a ring structure, and the camera, lens and fill light are arranged sequentially in the left-right direction, with the fill light located on the side closer to the first clamping element.

[0016] Compared with the prior art, this utility model, through the reasonable layout of the machine tool, the imaging module, and the first and second clamping elements, effectively solves the technical pain point of the inability to automatically identify the position of the magnetic ring wire after winding in the production of existing network transformers, and has the following significant beneficial effects:

[0017] First, the device achieves precise identification of the wire position. By using a first and second clamping element spaced apart and clamping the wires, it stably fixes the A and B colored wires to be identified in a specific area, avoiding shooting deviations caused by wire movement. Simultaneously, the shooting module is positioned on either side of the first clamping element, allowing for precise aiming at the wire area between the two clamping elements to capture the wire's vertical position clearly. This provides accurate image data for subsequent directional adjustments, significantly improving recognition accuracy and effectively eliminating subjective errors compared to manual identification.

[0018] Secondly, it adapts to automated production processes, improving production efficiency. The device has a simple structure and can be directly integrated into existing network transformer production lines without requiring significant additional space. In actual operation, the coordinated action of the clamping element and the imaging module quickly completes wire clamping and imaging recognition without manual intervention. It perfectly matches the pace of automated production, effectively replacing traditional manual inspection and adjustment steps, significantly reducing labor costs, and drastically shortening the recognition process time, thus contributing to improved overall production efficiency.

[0032] See Figures 1-5 A wire position identification device includes a machine base 10, a shooting module 20, a first clamping element 30, and a second clamping element 40; the shooting module 20 is disposed on either the left or right side of the first clamping element 30; when the shooting module 20 takes a picture, the first clamping element 30 and the second clamping element 40 are spaced apart and respectively clamp the wire, and the shooting module 20 takes a picture of the wire between the first clamping element 30 and the second clamping element 40.

[0033] This cable position identification device operates based on a collaborative logic of "stable clamping - precise imaging - intelligent recognition." Its core innovation lies in the structured layout of the clamping elements and the imaging module, which enables stable fixation and precise imaging of the cable to be identified. The image recognition process utilizes existing technology, and its specific working principle is as follows:

[0034] First, the magnetic ring is transported and positioned. In the production process of the network transformer, the magnetic ring that has completed the winding process (with A and B colored wires wound on it to identify the position) is precisely clamped by the transfer module of the production equipment (such as mechanical grippers or conveyor belt transfer mechanism) and transported to the preset working position of this device - that is, the collaborative working area of ​​the first clamping element 30 and the second clamping element 40 on the machine 10. After confirming that the magnetic ring has reached the designated position, the transfer module releases the magnetic ring and resets it, waiting for the next transfer task.

[0035] Secondly, the wires are clamped and fixed. When the magnetic ring reaches the preset position, the first clamping element 30 precisely clamps the wire segment close to the magnetic ring, and the second clamping element 40 clamps the wire segment away from the magnetic ring. By clamping at two points, the A and B colored wires to be identified are stably fixed in the straight area between the two elements, avoiding the wires from shaking due to their own elasticity or external interference, thus providing a stable imaging foundation for subsequent shooting.

[0036] Next, wire image acquisition. After the first clamping element 30 and the second clamping element 40 have secured the wire, the terminal sends a shooting command to the shooting module 20. Since the shooting module 20 is pre-installed on either the left or right side of the first clamping element 30 (such as the left or right side, which can be flexibly adjusted according to the production line space), its lens axis is pre-aligned with the wire area between the two clamping elements. At this time, the shooting module 20 immediately starts shooting to acquire high-definition images of the A and B color wires in a stable state between the two clamping elements, ensuring that the vertical positional relationship of the two wires in the radial direction is clearly captured, providing high-quality image data support for subsequent recognition.

[0037] Finally, image recognition and result output. The imaging module 20 transmits the acquired wire image data to the supporting terminal (such as an industrial control computer or PLC control system) in real time via a data transmission module (such as a wired Ethernet or wireless communication module). It should be noted that the terminal's image recognition process uses existing technology, relying solely on mature machine vision algorithms combined with preset standard templates (standard position images of A and B color wires) to quickly determine whether the current wire position meets the process requirements, generating a result of "position correct" or "position needs adjustment". The terminal then feeds the result back to the main control system of the production equipment. Based on this, the main control system instructs subsequent equipment: if the position is correct, it is conveyed to the next process; if the position is deviated, the magnetic ring direction is adjusted before conveying, achieving seamless integration between recognition and the production process.

[0038] See Figure 1 The machine tool 10 is equipped with a moving module 80, and the second clamping element 40 is connected to the moving module 80. The moving module 80 is used to drive the second clamping element 40 to move relative to the machine tool 10.

[0039] In this wire position identification device, the moving module 80, as a key motion driving component, provides core support for the device to achieve stable wire clamping, precise clamping, and flexible adjustment. Its specific functions are as follows:

[0040] From the perspective of structure and components, the moving module 80 is set on the machine tool 10 and is directly connected to the second clamping element 40. It can use existing mature moving components (such as multi-axis manipulators) without the need to develop new drive structures. This can reduce the development cost of the device and rely on the stability of existing components to ensure the accuracy of the movement, laying a reliable foundation for the realization of subsequent functions.

[0041] In the actual production feeding process, its role can be reflected in multiple dimensions: On the one hand, when the transfer module of the production equipment transfers the wire package to the first clamping element 30 and completes the clamping, the moving module 80 can drive the second clamping element 40 to move from the wire position close to the first clamping element 30 to the direction away from the first clamping element 30. During this process, the second clamping element 40 does not clamp the wire initially. Instead, it performs a "straightening" action through linear movement driven by the moving module 80. This effectively straightens any bent or tangled wires on the cable bundle, preventing irregular wire shapes from affecting subsequent image recognition accuracy. This provides a regular wire state for stable clamping and clear imaging. On the other hand, considering that colors A and B are the two longest wires in the cable bundle, the moving module 80 can adjust the spatial position of the second clamping element 40 to precisely align it with these two longest wires. This allows for targeted clamping of only colors A and B, eliminating interference from other short wires and ensuring that the wire to be identified is accurately clamped, further improving the uniqueness and accuracy of the identification target.

[0042] See Figures 1 to 4 It also includes a third clamping element 50, which is arranged at a distance from the first clamping element 30.

[0043] The third clamping element 50, as an important supplementary structure to this wire position identification device, is spaced apart from the first clamping element 30. Its core function is to solve the problem of identification failure caused by overlapping AB color wires, thus ensuring the device outputs stable and accurate identification results. Its specific functions are as follows:

[0044] In the normal working process of the device, the first clamping element 30 and the second clamping element 40 work together to clamp the wire and cooperate with the shooting module 20 to complete image acquisition. However, when the terminal backend recognizes the image, if it finds that the outlines of the A and B color wires are confused due to overlapping positions and the upper and lower positions cannot be determined, the third clamping element 50 can start a collaborative action to break the recognition deadlock. Specifically, when the recognition result shows that the wires are overlapping and cannot be determined, the second clamping element 40 will clamp the magnetic ring of the coil or the wire; then the first clamping element 30 releases the clamp on the wire, and the moving module 80 drives the second clamping element 40 and the coil fixed by it to move synchronously until the wire on the magnetic ring enters the preset clamping area of ​​the third clamping element 50; then the third clamping element 50 precisely clamps the wire, replacing the first clamping element 30 to form a new "third clamping element 50-second clamping element 40" clamping combination. Based on this, the second clamping element 40 performs a straightening action again to straighten the wire that may have shifted position due to movement. After re-stabilizing the clamping of the wire, the imaging module 20 can again photograph the wire between the two clamping elements. With the intervention of the third clamping element 50, the clamping position is switched and the wire state is re-normalized, effectively separating overlapping AB color wires, avoiding recognition failure caused by wire overlap, ensuring that the device can continuously output accurate position recognition results, and improving the device's adaptability to complex wire states and recognition reliability.

[0045] See Figures 1 to 4 The machine base 10 is equipped with a linear module 60, and a first clamping element 30 and a third clamping element 50 are arranged to move back and forth relative to the machine base 10. The linear module 60 is used to drive the first clamping element 30 and the third clamping element 50 to move back and forth relative to the machine base 10. Specifically, a mounting base can be provided at the sliding end of the linear module 60, and the first clamping element 30 and the third clamping element 50 can be mounted on the mounting base.

[0046] The linear module 60 is mounted on the machine base 10 and is used to drive the first clamping element 30 and the third clamping element 50 to move back and forth relative to the machine base 10. It adopts an existing belt-driven linear module or a lead screw linear module. Its core function revolves around optimizing the wire identification conditions and connecting subsequent adjustment processes, as detailed below:

[0047] On the one hand, the linear module 60 can adjust the position of the clamped wire by moving the first clamping element 30 and the third clamping element 50 back and forth. When the initial clamping position of the wire is not conducive to the imaging module 20 clearly capturing the positional relationship of the AB color wires, by adjusting the position of the two clamping elements, the wire can be aligned to a better shooting area, reducing the impact of wire occlusion or angle deviation on imaging, making it easier for the imaging module 20 to obtain a clear image and improving recognition accuracy.

[0048] On the other hand, after the wire position identification is completed, if the terminal determines that the positions of the A and B color wires do not meet the process requirements (their positions need to be swapped), the linear module 60 can drive the first clamping element 30 or the third clamping element 50 (selected according to the actual clamping state) to move, thereby driving the wire coil held by it to move synchronously to the preset position in front of the adjustment module 70. After the wire coil reaches the designated position, the adjustment module 70 can clamp the wire coil and rotate it 160° to realize the position swap of the A and B color wires, so that the wire position meets the requirements of subsequent processes, effectively connecting the identification and adjustment links and ensuring the continuity of the production process.

[0049] See Figures 3 to 5 The machine base 10 is provided with an adjustment module 70, which includes a rotary cylinder 710 on the machine base 10. The rotating end of the rotary cylinder 710 is equipped with a pneumatic gripper 720. The two clamping ends 730 of the pneumatic gripper 720 are used to clamp the magnetic ring. A magnet 740 for attracting the magnetic ring is provided between the two clamping ends 730. The adjustment module 70 is the core structure for correcting the position of AB color wires. Its function is to precisely clamp and rotate the magnetic ring when the wire position does not meet the process requirements, so that the wire position meets the standard. Specifically, the two clamping ends 730 of the pneumatic gripper 720 can stably clamp the magnetic ring, and the magnet 740 between the clamping ends 730 can attract the magnetic ring, further enhancing the clamping stability and preventing the magnetic ring from falling off during the adjustment process. After the wire coil is clamped, the rotating end of the rotary cylinder 710 can drive the pneumatic gripper 720 and the clamped magnetic ring to rotate 160°, quickly exchanging the upper and lower positions of the AB color wires, efficiently correcting the position deviation, and meeting the uniform requirements of the wire position in subsequent processes.

[0050] In this invention, the adjustment module 70 is spaced apart from the first clamping element 30 and the third clamping element 50. This allows the first clamping element 30 and the third clamping element 50 to transfer the coil to the adjustment module 70 for adjustment when they move back and forth.

[0051] See Figure 3 The shooting module 20 includes at least a camera 210 and a lens 220 mounted on the camera 210. The camera 210, as the imaging core, can capture the image of the wire between the first clamping element and the second clamping element (or the third clamping element); the lens 220 works with the camera 210 to optimize the imaging effect, clearly presenting the outline and relative position of the AB color wire, ensuring that the terminal backend can accurately determine the vertical position of the wire based on the high-quality image, providing a reliable basis for whether to adjust the direction of the wire later.

[0052] See Figure 3The shooting module 20 also includes a fill light 230. The fill light 230 has a ring structure, and the camera 210, lens 220, and fill light 230 are arranged sequentially in the left-right direction, with the fill light 230 located on the side closer to the first clamping element 30. As an important auxiliary component of the shooting module 20, the fill light 230 optimizes the imaging environment of the cable and provides light support for clearly capturing the details of the AB color cable. Specifically, the fill light 230 has a ring structure and is arranged sequentially in the left-right direction with the camera 210 and lens 220, and is located on the side closer to the first clamping element 30. It can provide uniform fill light to the cable area between the two clamping elements, avoiding problems such as blurred cable outlines and low color recognition due to insufficient light or uneven brightness; the ring light source can reduce the interference of reflection on the cable surface, clearly present the boundary and relative position of the AB color cable, further improve the quality of the image captured by the camera 210, and lay the foundation for the terminal backend to accurately identify the cable position.

[0053] In this utility model, the first clamping element 30, the second clamping element 40 and the third clamping element 50 all adopt existing pneumatic grippers.
