Description

Technical Field

[0001] This utility model relates to the field of current transformer production equipment, specifically a current transformer sorting device. Background Technology

[0002] As a critical piece of equipment in power systems, the quality of the bare core of the instrument transformer directly determines the metering accuracy, insulation reliability, and electromagnetic interference resistance of the finished product, thus affecting the stable operation of the entire power system. During the instrument transformer manufacturing process, the inspection and sorting of the bare core are crucial steps to ensure the final product quality.

[0003] However, existing technologies present several challenges in sorting bare transformer cores. First, most equipment uses belt conveyors, and due to their shape and material properties, bare cores are prone to rolling and shifting on the belt. This leads to positioning deviations at the inspection station, distorting the inspection data and affecting sorting accuracy. Second, existing multi-station coordination is poor; dimensional inspection, electrical performance testing, and sorting actions are mostly controlled independently. This easily results in missorting due to "inspection data not synchronizing with sorting actions," further impacting product quality. Utility Model Content

[0004] In order to overcome some of the problems mentioned in the background above, this invention provides a current transformer sorting device.

[0005] The technical solution adopted by this utility model is as follows: a current transformer sorting device includes a support platform, an anti-detachment frame and a bearing mechanism are arranged sequentially on the upper part of the support platform, the bearing mechanism is rotatably arranged in the anti-detachment frame for carrying and transmitting bare current transformer cores, and the anti-detachment frame is provided with a positioning guide mechanism, a detection mechanism and an unloading mechanism in its circumferential direction. The supporting mechanism includes multiple limiting grooves and signal sensors corresponding to the limiting grooves. The signal sensors are used to store the detection data of the corresponding bare core. The positioning and guiding mechanism is located above the supporting mechanism to accurately position the bare core at the detection position. The unloading mechanism includes a signal receiver and a pushing component. The signal receiver communicates with a signal sensor to obtain detection data, and the pushing component pushes the bare core into the corresponding guide plate according to the data.

[0006] Furthermore, the bearing mechanism also includes a bearing plate and a drive motor. Multiple limiting grooves are evenly distributed on the edge of the bearing plate. A flexible limiting plate is provided in the limiting groove. The limiting plate cooperates with the positioning and guiding mechanism to clamp and fix the bare core. The drive motor is fixed below the support platform, and its output end is connected to the bearing plate.

[0007] Furthermore, the unloading mechanism is provided in multiple ways, and each unloading mechanism corresponds to a different guide plate. The pushing component is connected to the support platform through a connecting plate and a support column. The pushing component includes a pusher plate and a telescopic device. The telescopic device controls the pusher plate to move according to the data obtained by the signal receiver, pushing the bare core into the corresponding guide plate.

[0008] Furthermore, the positioning mechanism includes a positioning guide plate and a fixing rod. The positioning guide plate has an arc-shaped structure and is disposed above the bearing mechanism, matching the rotation trajectory of the bearing mechanism. The fixing rod connects the positioning guide plate and the support platform to ensure that the position of the positioning guide plate is fixed.

[0009] Furthermore, the testing mechanism includes a size measurement module and an electrical performance testing module. The size measurement module is used to detect the physical dimensions of the bare core, and the electrical performance testing module is used to detect the electrical parameters of the bare core. The testing mechanism is connected to the signal sensor and transmits the test results to the signal sensor for storage.

[0010] Furthermore, the anti-detachment frame is provided with a feed inlet and multiple discharge outlets. The feed inlet is connected to an external conveying mechanism for feeding the bare core into the carrying mechanism. The discharge outlets correspond to the inlet of the guide plate and are used to export the sorted bare core.

[0011] Furthermore, it also includes a control system; the control system is connected to the drive motor, detection mechanism, signal sensor and unloading mechanism to realize automated sorting operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By employing a rotatable support mechanism in conjunction with an automated unloading assembly, the system enables continuous operation of bare cores from "feeding to positioning to detection to sorting," thereby improving detection and sorting speeds.

[0013] The paired design of signal sensors and signal receivers ensures that the detection results of each bare core accurately correspond to the sorting action, effectively avoiding missorting and improving the sorting quality of bare cores. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1-4 As shown, in some embodiments, a current transformer sorting device includes a support platform 1, which serves as the foundation for the entire transfer process. An anti-detachment frame 5 and a carrying mechanism 2 are sequentially arranged on the support platform 1. The anti-detachment frame 5 is an annular structure, fixed to the upper surface of the support platform 1 with countersunk bolts to prevent wear caused by friction between the carrying mechanism 2 and the anti-detachment frame 5 during rotation. The carrying mechanism 2 is the core component for conveying and positioning the bare core 8, and is rotatably mounted within the anti-detachment frame 5. A positioning guide mechanism 7, a detection mechanism 6, and a unloading mechanism 3 are arranged circumferentially around the anti-detachment frame 5. These mechanisms work together to ensure the smooth operation of the sorting process.

[0019] Specifically, the supporting mechanism 2 includes multiple limiting slots 24, and each limiting slot 24 is correspondingly equipped with a signal sensor 21. The main function of the signal sensor 21 is to store the detection data of its corresponding bare core 8 for subsequent processing and analysis.

[0020] In addition, the positioning guide mechanism 7 is set above the bearing mechanism 2. Its function is to ensure that the bare core 8 can be accurately positioned at the detection position, thereby improving the accuracy and efficiency of the detection.

[0021] Specifically, the unloading mechanism 3 includes a signal receiver 31 and a pushing component. The signal receiver 31 communicates with the signal sensor 21 to obtain detection data of the bare core 8. Based on this data, the pushing component accurately pushes the bare core 8 into the corresponding guide plate 4.

[0022] The testing mechanism 6 is used to perform quality testing on the bare core 8 on the support mechanism 2 and transmit the test data to the corresponding signal sensor 21.

[0023] The sorting device in this embodiment, through the coordinated action of various mechanisms, achieves automated detection and sorting of the bare core 8 of the current transformer, improving production efficiency and product quality. Specifically, a rotatable bearing mechanism 2, in conjunction with an automated unloading mechanism 3, enables continuous operation of the bare core 8 from "feeding-positioning-detection-sorting," increasing the detection and sorting speed. The paired design of the signal sensor 21 and signal receiver 31 ensures that the detection result of each bare core 8 accurately corresponds to the sorting action, effectively avoiding missorting and improving the sorting quality of the bare core 8.

[0024] Furthermore, in some embodiments, the supporting mechanism 2 also includes a supporting plate 22 and a drive motor 23. Multiple limiting grooves 24 are evenly distributed along the edge of the supporting plate 22, and each limiting groove 24 contains a flexible limiting plate 25. The limiting plate 25 works closely with the positioning and guiding mechanism 7 to clamp and fix the bare core 8, ensuring its stability and accuracy during the testing process.

[0025] The drive motor 23 is securely fixed below the support platform 1, and its output end is directly connected to the carrier plate 22, forming a complete drive system. The drive motor 23 is a servo motor, which precisely controls the rotation angle and speed of the carrier plate 22, thereby ensuring that the bare core 8 remains stable during the inspection process and avoiding the impact of vibration or displacement on the accuracy of the inspection results.

[0026] The flexible limiting plate 25 is made of a highly elastic material, which has good buffering performance. It can effectively absorb and disperse external forces while fixing the bare core 8, preventing any form of damage to the bare core 8.

[0027] The positioning guide mechanism 7 and the flexible limiting plate 25 are tightly fitted together, and the mechanical positioning ensures that the bare core 8 can be accurately placed in the predetermined position on the support plate 22. This precise positioning provides a reliable foundation for subsequent testing.

[0028] Furthermore, in some embodiments, multiple unloading mechanisms 3 are provided, each corresponding to a different guide plate 4. Specifically, the pushing component is stably connected to the support platform 1 through the connecting plate 11 and the support column 12, ensuring the stability of the pushing process and effectively avoiding possible shaking or deviation during the pushing process, thereby ensuring that the bare core 8 can be accurately pushed into the corresponding guide plate 4.

[0029] Specifically, the telescoping device 33 precisely controls the movement of the pusher plate 32 based on the data obtained by the signal receiver 31, thereby accurately pushing the bare core 8 into the corresponding guide plate 4.

[0030] The signal receiver 31 is installed on the side of the push plate 32 near the signal sensor 21, and the telescopic device 33 is controlled by the signal receiver 31 to perform the unloading operation.

[0031] It is worth noting that the telescopic device 33 in this embodiment is a pneumatic cylinder, which can precisely control the movement of the push plate 32 based on the data obtained from the signal receiver 31, making the entire unloading process more automated. This design greatly improves the efficiency and accuracy of sorting work.

[0032] Furthermore, in some embodiments, the positioning guide mechanism 7 includes a positioning guide plate 71 and a fixing rod 72. Specifically, the positioning guide plate 71 adopts an arc-shaped structure design and is positioned above the bearing mechanism 2, matching the rotation trajectory of the bearing mechanism 2 to ensure perfect coordination between the two during movement. The fixing rod 72 is responsible for firmly connecting the positioning guide plate 71 to the support platform 1, ensuring that the positioning guide plate 71 maintains a stable position during operation.

[0033] It is worth noting that the arc-shaped design of the positioning guide plate 71 can better fit the movement path of the bare core 8 on the bearing mechanism 2. When the bearing mechanism 2 drives the bare core 8 to rotate, the positioning guide plate 71 can guide and position the bare core 8, making the bare core 8 more accurate when it reaches the designated detection position.

[0034] Furthermore, in some embodiments, the testing mechanism 6 includes a size measurement module and an electrical performance testing module. The size measurement module uses optical measurement technology to detect the physical dimensions of the bare core 8, while the electrical performance testing module can comprehensively test key electrical parameters of the bare core 8, such as resistance, capacitance, and inductance, to ensure that the electrical performance of the bare core 8 meets relevant standards and requirements.

[0035] The detection mechanism 6 is closely connected to the signal sensor 21. Through an efficient signal transmission protocol, the detected size data and electrical parameter data are transmitted to the signal sensor 21 in real time and accurately for storage, so as to facilitate subsequent data analysis and processing and provide data support for the sorting operation of the entire bare core 8.

[0036] Furthermore, in some embodiments, the anti-detachment frame 5 is provided with a feed inlet and multiple discharge outlets. The feed inlet is connected to an external conveying mechanism for feeding the bare core 8 into the carrying mechanism 2, and the discharge outlets correspond to the inlet of the guide plate 4 for exporting the sorted bare core 8.

[0037] The multiple discharge ports enable the sorting and export of the bare cores 8. Each discharge port, through precise docking with the inlet of the guide plate 4, ensures the accuracy and orderliness of the bare cores 8 during the export process, thereby improving sorting efficiency and product quality.

[0038] Furthermore, in some embodiments, the device also includes a control system connected to the drive motor 23, detector, signal sensor 21, and unloading mechanism 3. Through a preset program, the control system can accurately determine the specifications and performance of the bare core 8 based on the dimensional and electrical parameter data transmitted from the detection mechanism 6, and issue corresponding commands to control the drive motor 23 and the unloading mechanism 3. During the automated sorting process, the control system monitors the operating status of each component in real time, ensuring the stability and reliability of the entire sorting process. In the event of any abnormality, it can immediately issue an alarm and take corresponding protective measures, effectively preventing equipment damage and production accidents.

[0039] The workflow of this utility model is divided into four stages: feeding, positioning, detection, and sorting, as detailed below: I. Feeding Stage The external conveying mechanism transports the bare core 8 of the current transformer to be tested to the feed port of the anti-detachment frame 5, and the bare core 8 slides into one of the limiting grooves 24 of the bearing plate 22 along the feed port.

[0040] II. Positioning Phase During the rotation of the support plate 22 driven by the drive motor 23, the bare core 8 moves with the limiting groove 24 to the position of the positioning guide mechanism 7, and the guide slope of the positioning guide plate 71 contacts the side of the bare core 8. Due to the arc-shaped trajectory of the positioning guide plate 71, the bare core 8 slides along the inner wall of the limiting groove 24 under the guidance of the slope, gradually approaching the limiting plate 25. The limiting plate 25 enables the bare core 8 to achieve centering and positioning, and then the bare core 8 is transported to the inspection station.

[0041] III. Testing Phase When the bare core 8 rotates with the carrier plate 22 to the first inspection station appearance inspection module, the optical inspection equipment takes an image of the bare core 8. The image data is transmitted to the image recognition system built into the control system. The control system determines whether the size of the bare core 8 meets the requirements and makes a preliminary judgment on whether the coil winding of the bare core 8 is uniform. The control system then transmits the inspection results to the signal sensor 21.

[0042] The carrier plate 22 continues to rotate to the magnetic property detection module at the second detection station, and synchronously collects the magnetic field signals of the bare core 8 at different circumferential positions through the Hall sensor. The detection results are also judged by the control system and fed back to the signal sensor 21.

[0043] IV. Sorting Stage The bearing plate 22 continues to rotate. When the bare core 8 that has completed the inspection moves to the corresponding unloading position, such as the "fully qualified" unloading port, the signal receiver 31 at the unloading port controls the telescopic device 33 to push the push plate 32 to retract based on the signal feedback from the signal sensor 21, pushing the bare core 8 from the limiting groove 24 into the guide plate 4. The bare core 8 slides along the guide plate 4 into the finished product bin below. If a certain indicator of the bare core 8 is unqualified, such as the appearance, when it rotates to the corresponding unqualified unloading port, the corresponding unloading mechanism 3 pushes it into the waste bin.

[0044] After sorting is completed, the telescopic device 33 extends, the push plate 32 resets, and the carrier plate 22 continues to rotate, entering the next working cycle.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
