It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0063] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0064] Inductors are important components of electronic components and various instruments. Among them, common-mode inductors are one of the commonly used inductors, which are used to filter common-mode electromagnetic interference signals and suppress the outward radiation of electromagnetic waves generated by high-speed signal lines.

[0065] In the manufacturing process of existing common-mode inductors, processes such as foot wrapping, solder dispensing and testing are generally done manually, which is not only costly and inefficient, but also difficult to ensure the consistency of the finished product.

[0066] In response to the above technical issues, such as Figure 1 , Figure 2 As shown, in the first aspect, this embodiment proposes a common-mode inductor production line, including a winding and material taking cycloidal machine D, a foot wrapping machine A, a post-process machine B and a testing machine C arranged in sequence along the width direction; the winding and material taking cycloidal machine D is used to transfer the magnetic core to the foot wrapping machine A; the foot wrapping machine A is used to wrap the foot of the magnetic core, and transfer the foot-wrapped magnetic core to the post-process machine B; the post-process machine B is used to solder the foot-wrapped magnetic core to obtain a finished magnetic core and transfer the finished magnetic core to the testing machine C; the testing machine C is used to spray code and test the finished magnetic core, and unload the finished magnetic core that has passed the test from a tray.

[0067] As can be seen from the above, by setting up the winding material cycloid machine D, the foot wrapping machine A, the back-end machine B and the testing machine C, the process flow of the inductor is integrated, manual work is abandoned, production costs are reduced, and production efficiency is improved. At the same time, the winding material cycloid machine D, the foot wrapping machine A, the back-end machine B and the testing machine C are independent split structures, which are spliced ​​in the width direction to form a production line, which is convenient for installation and adjustment, and is also conducive to the installation and debugging of the machine; the semi-finished magnetic core is safely transported from the winding machine to the foot wrapping machine A through the winding material cycloid machine D, and the foot is wrapped and cut through the foot wrapping machine A, and the magnetic core completed by the foot wrapping is transported to the back-end machine B, and the back-end machine B solders and dispenses glue on the magnetic core to ensure the soldering quality of the magnetic core, reduce artificial soldering defects, ensure the flatness of the glue, and save the detection steps. The magnetic core is sprayed and tested by the testing machine C, and the material is automatically unloaded on the plate, which effectively improves production efficiency, reduces R&D costs, and improves the yield rate and product quality.

[0068] like Figure 3 , Figure 5 As shown, in some embodiments, the winding and reclaiming cycloidal machine D includes:

[0069] Winding base D10;

[0070] The material picking fixture switching module D20 is arranged on the winding base D10, and the material picking fixture switching module D20 includes two material picking seats D210 arranged at intervals in the width direction;

[0071] The winding rotation module D30 is arranged on the winding base D10 and connected to the material taking jig switching module D20. The winding rotation module D30 is used to rotate the long wire of the magnetic core;

[0072] The winding material taking cylinder D220 is arranged on the winding base D10. The winding material taking cylinder D220 drives the winding rotating module D30 and the two material taking seats D210 to move along the length direction and changes the distance between the two material taking seats D210 in the width direction so that the material taking seats D210 can take the magnetic core from the winding machine.

[0073] The rear loading and transporting module D40 is disposed on the winding base D10. The rear loading and transporting module D40 is used to absorb the magnetic core and transfer the magnetic core from the material taking seat D210 to the winding rotating module D30, and then from the winding rotating module D30 to the foot binding machine A.

[0074] The material picking jig switching module D20 and the winding rotating module D30 can move in the length direction under the action of the winding material picking cylinder D220, so that the magnetic cores on the material picking jig switching module D20 and the winding rotating module D30 are respectively located directly below the rear-stage loading and handling module D40, so that the rear-stage loading and handling module D40 can absorb the magnetic core; when the material picking jig switching module D20 receives the magnetic core from the winding machine, the winding material picking cylinder D220 drives the magnetic core of the jig switching module to be located at the rear The first-stage loading and handling module D40 is directly below the rear-stage loading and handling module D40, the rear-stage loading and handling module D40 sucks the magnetic core, then the winding material taking cylinder D220 drives the winding rotating module D30 to be located directly below the rear-stage loading and handling module D40, the rear-stage loading and handling module D40 places the magnetic core on the winding rotating module D30, when the winding rotating module D30 rotates the long wire of the magnetic core, the rear-stage loading and handling module D40 sucks the magnetic core on the winding rotating module D30 and transfers the magnetic core to the foot binding machine A.

[0075] The winding material taking cylinder D220 drives the two material taking seats D210 to move in the length direction and changes the distance between the two material taking seats D210 in the width direction so that the material taking seats D210 are aligned with the magnetic core on the winding machine, thereby being able to pick up two magnetic cores in different positions.

[0076] It should be noted that each material taking seat D210 has two material taking stations, and each material taking station receives a magnetic core from the winding machine; the specific structure and working principle of the winding machine are prior art and will not be repeated in this application.

[0083] Among them, the two material picking seats D210 correspond to the two material picking cylinders D2206 one by one, and the material picking seats D210 are arranged on the corresponding material picking cylinders D2206.

[0084] The telescopic rod of the material picking drive cylinder drives the first material picking slide D2202 to move along the length direction, and drives the two second material picking support seats D2204 to move along the second material picking slide D2203. Since the second material picking slide D2203 has a preset angle with the length direction, the spacing between the two second material picking support seats D2204 in the width direction changes, and the first material picking support seat D2205 moves with the corresponding second material picking support seat D2204, so that the first material picking support seat D2205 moves on the first material picking slide D2202, and the material picking seat D210 and the material picking cylinder D2206 move with the corresponding first material picking support seat D2205, so that the material picking seat D210 moves to the magnetic core of the winding machine, and the material picking cylinder D2206 is used to adsorb the magnetic core to the material picking seat D210.

It refers to the ratio of the inductive reactance presented by the inductor to its equivalent loss resistance when it works under an AC voltage of a certain frequency. The higher the Q value of the inductor, the smaller its loss and the higher its efficiency; the specific structure and working principle of the electrical tester are all existing technologies and will not be repeated in this application.

[0159] It should also be noted that the withstand voltage test seat 3105 includes a withstand voltage tester, which is used to perform withstand voltage tests on the finished magnetic core. The withstand voltage test is to detect whether the product insulation structure can withstand the internal overvoltage of the power system. If it can withstand, it is qualified; the withstand voltage test refers to the test of the withstand voltage ability of various electrical devices, insulating materials and insulating structures. The process of applying high voltage to insulating materials or insulating structures without destroying the performance of insulating materials is called withstand voltage test. Generally speaking, the main purpose of the withstand voltage test is to check the ability of insulation to withstand working voltage or overvoltage, and then to check whether the insulation performance of the product equipment meets the safety standards;

[0160] The basic principle of the withstand voltage test is to apply a voltage higher than the normal working voltage to the insulator of the device under test for a specified period of time. If the insulation between them is good enough, the voltage applied will only produce a small leakage current. If the leakage current of the insulator of a device under test remains within the specified range within the specified time, it can be determined that the device under test can operate safely under normal operating conditions;

[0161] The specific structure and working principle of the voltage withstand tester are all existing technologies and will not be repeated in this application.
