Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] On the one hand, see Figure 1-13 The utility model embodiment discloses a magnetic material double-sided testing and sorting machine, including: a frame 1, a feeding mechanism 2, a magnetic material lower surface testing mechanism 3, a magnetic material upper surface testing mechanism 4, a transfer mechanism 5, a feeding mechanism 6 and a controller 12.

[0044] The frame 1 is provided with a first conveying mechanism 7 and a second conveying mechanism 8 which are spaced apart from each other, and the second conveying mechanism 8 is located in the extension direction of the first conveying mechanism 7; wherein the first conveying mechanism 7 includes a first motor and a first conveying belt, and the second conveying mechanism 8 includes a second motor and a second conveying belt.

[0045] The feeding mechanism 2 is arranged at one side of the first conveying mechanism 7, and is used to convey the magnetic materials to be tested to the first conveying mechanism 7. The magnetic materials to be tested are placed on the feeding mechanism 2 first, and then the feeding mechanism 2 conveys the magnetic materials one by one to the first conveyor belt.

[0046] The magnetic material lower surface testing mechanism 3 is arranged on the frame 1 between the first conveying mechanism 7 and the second conveying mechanism 8, and is used to test the lower surface of the magnetic material.

[0047] The magnetic material upper surface testing mechanism 4 is arranged above the second conveying mechanism 8, and is used to test the upper surface of the magnetic material on the second conveying mechanism 8. Through the cooperation between the magnetic material lower surface testing mechanism 3 and the magnetic material upper surface testing mechanism 4, both sides of the magnetic material can be tested, and the testing process is specifically to test the quality factor of the magnetic material.

[0048] The transfer mechanism 5 is arranged on the frame 1 between the first conveying mechanism 7 and the second conveying mechanism 8, and is used to transfer the magnetic material on the first conveying mechanism 7 to the magnetic material lower surface testing mechanism 3, so that the magnetic material lower surface testing mechanism 3 can test the lower surface of the magnetic material, and at the same time, the magnetic material whose lower surface has been tested by the magnetic material lower surface testing mechanism 3 can be transferred to the second conveying mechanism 8, so that the magnetic material upper surface testing mechanism 4 can test the upper surface of the magnetic material; preferably, the transfer mechanism 5 is at an equal distance from the first conveyor belt and the second conveyor belt, and has two execution ends. Through the setting of the two execution ends, the magnetic material on the first conveyor belt and the magnetic material on the magnetic material lower surface testing mechanism 3 can be transferred simultaneously.

[0049] The unloading mechanism 6 has a relatively low-grade station 61 , a middle-grade station 62 and a relatively high-grade station 63 .

[0050] The controller 12 is electrically connected to the first conveying mechanism 7, the second conveying mechanism 8, the feeding mechanism 2, the magnetic material lower surface testing mechanism 3, the magnetic material upper surface testing mechanism 4, the transfer mechanism 5 and the unloading mechanism 6. The controller 12 controls each mechanism accordingly to achieve mutual coordination between the mechanisms and realize the automation and continuity of the working process of the magnetic material double-sided testing and sorting machine.

[0051] Among them, the controller 12 sends a control signal to the unloading mechanism 6 according to the test results of the magnetic material by the magnetic material lower surface testing mechanism 3 and the magnetic material upper surface testing mechanism 4, and the unloading mechanism 6 unloads the magnetic material from the corresponding low-grade station 61, the middle-grade station 62 or the high-grade station 63 according to the control signal. Specifically, the test result is the average value of the Q value of the magnetic material measured by the magnetic material lower surface testing mechanism 3 and the magnetic material upper surface testing mechanism 4. A comparator is provided in the controller 12. By using the comparator, the average value of the Q value of the tested magnetic material is compared with the standard range value, and then the tested magnetic material is divided into low-grade magnetic material, middle-grade magnetic material and high-grade magnetic material, and different magnetic materials are unloaded separately to achieve the sorting of magnetic materials.

[0052] It should be noted that the utility model can realize automatic transfer and testing of magnetic materials through the arrangement of the magnetic material lower surface testing mechanism 3, the magnetic material upper surface testing mechanism 4 and the transfer mechanism 5; at the same time, through the arrangement of the unloading mechanism 6 and the controller 12, the magnetic materials can be automatically sorted and unloaded according to the test results of the magnetic material lower surface testing mechanism 3 and the magnetic material upper surface testing mechanism 4. This improves the test method of manually placing components, which is easily affected by the operator himself and leads to inaccurate test results, resulting in misjudgment, thereby improving the test efficiency of magnetic materials and the accuracy of test results.

The lifting and lowering of the second mounting plate 413 is controlled by the lifting cylinder 412, thereby driving the lifting and lowering of the second testing coil 414, so that the second testing coil 414 contacts the upper surface of the magnetic material clamped by the clamping component 42, so as to measure the quality factor of the upper surface of the magnetic material. Specifically, the second testing coil 414 is fixed to the second mounting plate 413 by the second fixing member 415. In other embodiments, the lifting cylinder 412 is also configured as a structure with adjustable height together with the bracket 411 , so as to increase the height adjustment range of the second test coil 414 .

The material clamp 421 is installed on the mounting frame 423. The limit plate 424 is arranged on the frame 1 below the lifting cylinder 412. Under the lifting action of the lifting cylinder 422 and the limiting action of the limit plate 424, the material clamp 421 fixes the magnetic material on the second conveying mechanism 8 in the material clamp 421 for testing by the second test coil 414.
