Description

Technical Field

[0001] This utility model relates to the field of network transformer production and testing technology, and in particular to a network transformer pin winding photographing device. Background Technology

[0002] As a key component in the field of data communication, the quality of the pin winding of network transformers directly affects the stability and reliability of signal transmission. During the production process of network transformers, pin winding inspection is a crucial step in ensuring product quality. The method of capturing images of the pin winding and having a back-end terminal perform inspection based on these images has become a widely adopted inspection method in the industry due to its high efficiency and accuracy.

[0003] However, in actual shooting, the pins of network transformers are usually arranged in two rows, a structural feature that presents a significant challenge to the shooting process. Because the two rows of pins overlap spatially, conventional shooting methods easily result in the left and right rows of pins obscuring and overlapping each other in the image. This overlap obscures the detailed information of the pin winding in the captured image, making it difficult for the backend terminal to accurately identify the winding status of each pin during image analysis and inspection, such as whether the winding is secure, or whether there are any defects like missing or incorrect windings.

[0004] Therefore, how to achieve separate imaging of the two rows of pins of a network transformer and effectively avoid overlap of the left and right rows of pins in the image has become a key issue in improving the production and testing efficiency and accuracy of network transformers, and an efficient and reliable solution is urgently needed.

[0006] A network transformer pin winding imaging device designed for this purpose includes a fixed base, a rotating module, a camera module, and a single-sided blocking module.

[0007] The mounting base is provided with a receiving cavity for accommodating the network transformer;

[0008] The rotating module is connected to the fixed base; the rotating module is used to drive the fixed base to rotate, so that the network transformer can perform commutation detection.

[0009] The camera module is mounted on one side of the mounting base and is used to photograph the pins of the network transformer.

[0010] The single-sided blocking module includes at least a blocking element and a driving element; the blocking element is movably disposed relative to the fixed base, and the driving element is used to drive the blocking element to move relative to the fixed base;

[0011] The blocking element can be moved between the two rows of pins of the network transformer, so that the camera module only takes pictures of one row of pins at a time.

[0012] Preferably, the system also includes an illumination element for providing supplemental lighting to the network transformer.

[0013] Preferably, the lighting element has a ring-shaped structure and the light-emitting surface is positioned facing the mounting base;

[0014] The mounting base, lighting element, and camera module are arranged in a straight line.

[0015] Preferably, the single-sided blocking module further includes a mounting base, and the blocking element is rotatably connected to the mounting base;

[0016] The driving element is used to drive the blocking element to rotate relative to the mounting base, so that the blocking element moves between a first position and a second position;

[0017] When the blocking element is in the first position, the blocking element is located between two rows of pins.

[0018] Preferably, the driving element is a cylinder, and the cylinder shaft of the cylinder is hinged to a connecting rod, which is hinged to the blocking element.

[0024] Compared with the prior art, this utility model, through its reasonable structural design, can effectively solve the problem of easy overlap when photographing two rows of pins in the prior art, and has significant beneficial effects.

[0025] First, the blocking element of the single-sided blocking module can be moved between the two rows of pins. In conjunction with the camera module, it enables only one row of pins to be photographed at a time, completely avoiding the overlap of the left and right rows of pins in the image. This greatly improves the clarity and accuracy of the captured image, providing high-quality image evidence for the accurate detection of the back-end terminal, thereby improving the accuracy of the pin winding detection of the network transformer.

[0026] Secondly, the rotating module can drive the fixed base and network transformer to rotate to achieve reversal detection. Combined with the synergistic effect of the single-sided blocking module, the position of the network transformer can be frequently adjusted manually to complete the separate imaging of the two rows of pins, which simplifies the detection process, saves labor costs, and greatly improves detection efficiency.

[0038] See Figures 1-3A network transformer pin winding imaging device includes a fixed base 10, a rotating module 20, a camera module 30, and a single-sided blocking module 40. The fixed base 10 is provided with a receiving cavity 110 for accommodating a network transformer 100. The rotating module 20 is connected to the fixed base 10 and is used to drive the fixed base 10 to rotate, so that the network transformer 100 can be detected for commutation. The camera module 30 is disposed on one side of the fixed base 10 and is used to image the pins of the network transformer 100. The single-sided blocking module 40 includes at least a blocking element 410 and a driving element 420. The blocking element 410 is movable relative to the fixed base 10, and the driving element 420 is used to drive the blocking element 410 to move relative to the fixed base 10. The blocking element 410 can be moved between two rows of pins of the network transformer 100, so that the camera module 30 can only image one row of pins at a time.

[0039] The working principle of this network transformer pin winding imaging module is as follows:

[0040] In the initial state, the blocking element 410 of the single-sided blocking module 40 is in the second position, that is, it does not block the pins of the network transformer 100. At this time, under the action of the robot arm, the network transformer 100 to be tested is accurately placed into the receiving cavity 110 of the fixed seat 10, and its two rows of pins face the side where the camera module 30 is located.

[0041] When the image capture begins, the drive element 420 drives the blocking element 410 to move from the second position to the first position, that is, the blocking element 410 is precisely inserted between the two rows of pins of the network transformer 100, blocking one row of pins. Subsequently, the camera module 30 is activated to capture an image of the unblocked row of pins, obtaining a clear image of the single row of pins.

[0042] After the first row of pins is photographed, the drive element 420 is activated again, driving the blocking element 410 to reset from the first position to the second position, releasing the blocking of the pins. Then, the rotating module 20 drives the fixed base 10 and the network transformer 100 to rotate, realizing the reversal, so that the row of pins that was originally blocked turns towards the camera module 30.

[0043] Then, the driving element 420 drives the blocking element 410 to move from the second position to the first position again, inserting it between the two rows of pins (at this time, the row of pins that has already been photographed is blocked). The camera module 30 is activated again to photograph the other row of pins that has not been blocked. After the photographing is completed, the driving element 420 drives the blocking element 410 to reset from the first position to the second position.

[0044] After both rows of pins have been photographed, the robotic arm moves to remove the network transformer 100 that has been tested from the receiving cavity 110, completing a full two-row pin photographing and testing process.

[0045] See Figures 1 to 3 The system also includes an illumination element 50, which provides supplemental lighting for the network transformer 100. The illumination element 50 plays a crucial supplemental lighting role in the network transformer pin winding imaging module, providing stable and suitable lighting conditions for the entire imaging and inspection process. When imaging the pins of the network transformer 100, insufficient ambient light or uneven light distribution can easily lead to excessive contrast and blurred details in the images captured by the camera module 30, thus affecting the accurate identification of the pin winding status by the backend terminal. The illumination element 50 can specifically supplemental light to the pin area of ​​the network transformer 100, ensuring that the pins and their winding details are adequately illuminated, reducing image quality defects caused by lighting issues. The illumination element 50 can be selected from existing illumination elements as needed.

[0046] See Figures 1 to 3 The lighting element 50 has a ring structure and its light-emitting surface is positioned facing the fixing base 10; the fixing base 10, the lighting element 50, and the camera module 30 are arranged in a straight line.

[0047] The ring-shaped lighting element provides surround lighting to the pin area of ​​the network transformer 100 on the mounting base 10 from multiple angles, avoiding localized shadows that may occur with unidirectional lighting. This makes the pins and winding details more evenly and brightly illuminated, effectively eliminating blind spots in pin gaps or overlapping windings. The emitting surface facing the mounting base 10 ensures that the light is focused maximally on the pin area to be photographed, reducing light dispersion and waste, and improving the targeting and intensity of the lighting.

[0048] Furthermore, the linear arrangement of the mounting base 10, the illumination element 50, and the camera module 30 ensures that during shooting, light from the camera module 30 evenly covers the pin area along a straight path. This results in a more consistent light distribution in the captured image, avoiding uneven brightness caused by light refraction or angular deviations. This collaborative design further enhances the clarity and detail reproduction of the captured images, laying a more solid foundation for accurate pin winding detection in the backend terminal and significantly improving the reliability and efficiency of the detection.

[0049] See Figures 1 to 3In the first movable embodiment of the blocking element 410, the single-sided blocking module 40 further includes a mounting base 430, to which the blocking element 410 is rotatably connected. The driving element 420 drives the blocking element 410 to rotate relative to the mounting base 430, causing the blocking element 410 to move between a first position and a second position. When the blocking element 410 is in the first position, it is located between two rows of pins. When the driving element 420 is working, it drives the blocking element 410 to rotate relative to the mounting base 430, switching it between the first and second positions. Initially in the second position, after rotation to the first position, the blocking element 410 is exactly between the two rows of pins, completing the blocking; a reverse rotation resets it to the second position.

[0050] Based on the first moving embodiment of the blocking element 410, the driving element 420 adopts a cylinder, and its cylinder shaft is connected to the blocking element 410 through a hinged connecting rod 440, which can efficiently transmit power and drive the blocking element 410 to rotate stably, realize the precise switching between the first position and the second position, and ensure the reliability of the blocking and resetting actions.

[0051] Based on the first moving embodiment of the blocking element 410, the driving element 420 adopts a motor, which is connected to the rotating shaft of the blocking element 410 through a transmission connection. It can directly drive the blocking element 410 to rotate, realize the rapid switching between the first position and the second position, and ensure rapid action response and accurate positioning.

[0052] In this invention, in a second movable embodiment of the shielding element 410, the single-sided shielding module 40 further includes a mounting base 430. The shielding element 410 is linearly movable relative to the mounting base 430. The driving element 420 is a cylinder, and the cylinder shaft is connected to the shielding element 410. In this embodiment, the shielding element 410 is positioned directly above the receiving cavity 110. Driven by the driving element 420, the shielding element 410 moves from top to bottom between the two rows of pins of the network transformer 100. In this embodiment, the shielding element 410 is positioned directly above the receiving cavity 110 and can move linearly along the mounting base 430. The cylinder shaft of the driving element 420 (cylinder) is connected to the shielding element 410, driving it to move from top to bottom between the two rows of pins (first position). After the image is captured, the cylinder drives the shielding element 410 to return to the second position.

[0053] See Figure 3 The camera module 30 includes a camera 310 and a lens 320 mounted on the camera 310. Both the camera and the lens are existing commercially available products. The lens 320 can accurately focus on the pin area of ​​the network transformer 100, while the camera 310 clearly images the pin winding details captured by the lens, providing high-quality image data for subsequent inspection.

[0054] See Figure 2 and Figure 3 The camera module 30 further includes a fixing rod 330 and an adjustment seat 340 mounted on the fixing rod 330, and the camera 310 is mounted on the fixing rod 330. The fixing rod 330 provides stable support for the camera 310, and the adjustment seat 340 facilitates the adjustment of the position of the camera 310 to ensure that the shooting angle and focal length are accurately adapted to the pin area.

[0055] Specifically, the adjustment base 340 and the fixed rod 330 are connected by a sliding fit, allowing for quick adjustment of the distance between the camera 310 and the network transformer 100 along the axial direction of the fixed rod 330. The adjustment base 340 is threadedly connected to a locking knob that abuts against the fixed rod 330. Loosening the knob allows for smooth sliding adjustment, while tightening it quickly locks the position, enabling flexible and stable adjustment of shooting distance and angle to meet the shooting needs of different network transformer specifications.

[0056] In this invention, the rotating module 20 uses a motor or a rotary cylinder, and its rotating shaft is connected to the fixed base 10. It can accurately drive the fixed base 10 and the network transformer 100 to rotate, and quickly realize the reversal so that the camera module 30 can take pictures of another row of pins, thereby improving the detection efficiency.

[0057] This utility model also includes a frame 60, on which the rotating module 20, camera module 30 and single-sided blocking module 40 are mounted.

[0058] Specifically, the lighting element 50 is fixed on the frame 60 by the lamp holder 500.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
