[0096] As shown in Figures 6-9 In some embodiments, the detection mechanism 310 includes:

[0097] The code spraying detection device 3101 is arranged on the rack 100, the code spraying detection support frame 3102 and the code spraying detection camera 3103 arranged on the code spraying detection support frame 3102;

[0098] The electrical test seat 3104 is arranged on the rack 100, and the electrical test seat 3104 is used for electrical test of the finished product magnetic core;

[0099] The pressure resistance test seat 3105 is arranged on the rack 100, and is used for pressure resistance test of the finished product magnetic core;

[0100] The transition test seat 3106 is arranged on the rack 100, and the transition test seat 3106, the pressure resistance test seat 3105 and the electrical test seat 3104 are arranged at equal intervals along the length direction;

[0101] The solder test seat 3107 is arranged on the rack 100, and is used for testing the pin of the finished product magnetic core after soldering;

[0105] It should be further noted that the electrical test seat 3104 comprises an electrical tester. The Q value of the material is tested through the electrical tester, and the test value is used to judge whether the finished product magnetic core is qualified. The inductance Q value is the quality factor of the inductance, which is a main parameter for measuring the inductor. It refers to the ratio of the inductive reactance to the equivalent loss resistance of the inductor when the inductor works under a certain frequency of alternating voltage. The higher the Q value of the inductor, the smaller the loss and the higher the efficiency.

[0106] It also needs to be explained that the voltage withstand test seat 3105 includes a voltage withstand tester, and the finished product magnetic core is subjected to voltage withstand test by the voltage withstand tester. The voltage withstand test is to detect whether the insulation structure of the product can withstand the internal overvoltage of the power system, and can withstand it, that is, it is qualified. The voltage withstand test refers to the test on the withstand voltage capacity of various electrical devices, insulation materials and insulation structures. In the case of not damaging the performance of the insulation material, the process of applying high voltage to the insulation material or insulation structure is called voltage withstand test. In general, the main purpose of voltage withstand test is to check the insulation withstand working voltage or overvoltage capacity, and then to check whether the insulation performance of the product equipment meets the safety standard;

[0107] The basic principle of voltage withstand test is to apply a voltage higher than the normal working voltage to the insulation body of the tested device and maintain it for a specified time. If the insulation is good enough, the voltage applied will only produce a small leakage current. If the leakage current of the insulation body of a tested device remains within a specified range within a specified time, it can be determined that the tested device can safely operate under normal operating conditions;

[0108] The specific structure and working principle of the voltage withstand tester are prior art, and will not be described here.

[0109] It also needs to be explained that the finished product magnetic core has magnetism, and the finished product magnetic core is provided with a pin, which is connected with the electrical tester and the voltage withstand tester.

[0110] It also needs to be explained that, as shown in Figure 9 The solder test seat 3107 includes a solder test support 3118, a lamp 3119 and a solder detection camera 3120. The solder test support 3118 is provided with a fixing ring, the lamp 3119 is installed in the fixing ring, and the solder detection camera 3120 is installed on the solder test support 3118 and located below the fixing ring. The solder detection camera 3120 is a CCD camera, and the solder detection camera 3120 is electrically connected with the display mechanism. After imaging by the solder detection camera 3120, the imaging can be viewed through the display mechanism, so as to check whether the pin after soldering of the finished product magnetic core meets the requirements.

[0111] As shown in Figure 6 In some embodiments, the test carrying device 3108 includes a carrying support frame 3109, a carrying rotating shaft, a carrying motor 3110, a carrying transition rod 3111, a sliding block, a carrying driving frame 3114 and three suction material assemblies.

[0112] The carrying support frame 3109 is provided with a circular arc guide groove 3112; a carrying rotating shaft is rotatably arranged on the carrying support frame 3109 and coaxially arranged with the circular arc guide groove 3112; a carrying motor 3110 is arranged on the carrying support frame 3109 and connected with the carrying rotating shaft; one end of a carrying transition rod 3111 is arranged on the carrying rotating shaft, and the carrying transition rod 3111 is provided with a sliding groove 3113 which is in communication with the circular arc guide groove 3112; a sliding block is movably arranged in the sliding groove 3113 and the circular arc guide groove 3112; a carrying driving frame 3114 is rotatably arranged on the sliding block; three material suction assemblies are arranged on the carrying driving frame 3114, and the three material suction assemblies are arranged at equal intervals along the length direction, and the material suction assemblies are used for magnetically adsorbing finished product magnetic cores; wherein the distance between two adjacent material suction assemblies is L1, the distance between the electrical test seat 3104 and the voltage test seat 3105 is L1, and the movement stroke of the carrying driving frame 3114 in the length direction is L1.

[0113] The carrying motor 3110 drives the carrying rotating shaft to rotate, the carrying transition rod 3111 rotates with the rotating shaft, and the sliding block and the carrying driving frame 3114 move along the circular arc guide groove to make a circular motion, the carrying driving frame 3114 is rotatably arranged on the sliding block, so that the carrying driving frame 3114 is always parallel to the length direction, and deviation of the carrying driving frame 3114 is avoided, the distance between the material suction assemblies, the electrical test seat 3104 and the voltage test seat 3105, and the movement stroke of the carrying driving frame 3114 in the length direction are equal, so that the material suction assemblies can always be aligned with the test seats to realize point-to-point carrying of the finished product magnetic cores.

[0114] It should be noted that the central angle of the circular arc guide groove 3112 is 180°, when the carrying driving frame 3114 moves to one end of the circular arc guide groove 3112, the three material suction assemblies are respectively one-to-one corresponding to the finished product magnetic cores on the finished product conveying and testing mechanism 200, the electrical test seat 3104 and the voltage test seat 3105; when the carrying driving frame 3114 moves to the other end of the circular arc guide groove 3112, the three material suction assemblies are respectively one-to-one corresponding to the electrical test seat 3104, the voltage test seat 3105 and the transition test seat 3106;

[0115] For example, as shown in FIG. 9, the carrying driving frame 3114 is provided with a first material suction assembly 3116, a second material suction assembly 3117 and a third material suction assembly 3118, and the three material suction assemblies are arranged at equal intervals along the length direction. Figure 6As shown, the three suction assemblies are respectively a first suction assembly 3115, a second suction assembly 3116, and a third suction assembly 3117. When the carrying motor 3110 drives the carrying drive frame 3114 to move to one end of the circular arc guide groove 3112, the first suction assembly 3115, the second suction assembly 3116, and the third suction assembly 3117 correspond to the product magnetic core, the electrical test seat 3104, and the voltage test seat 3105 on the product conveying and detecting mechanism 200 one by one. The first suction assembly 3115 sucks the product magnetic core that has completed the code detection on the product conveying and detecting mechanism 200.
