[0037] Reference Figure 4 As shown, a Gaussian detection method includes the above-mentioned Gaussian detection machine, a controller 7 and the following steps:

[0038] S1: preset detection parameter range, detection value and trigger parameter;

[0039] S2: The Gaussmeter probe 4 performs measurement according to the trigger parameter and generates a measurement value;

[0040] S3: Screening for normal values ​​within the test parameter range;

[0041] S4: Determine the value between the normal value and the test value;

[0042] S5: According to the determination result in S4, the working state of the Gaussian detector is controlled.

[0043] If the normal value is greater than or equal to the test value, the Gaussian detector continues to work;

[0044] If the normal value is smaller than the test value, a defective product is recorded and the Gaussian detector continues to work.

[0045] First, according to the number and arrangement of the magnetized magnets in the mold 5, the detection movement process of the Gaussmeter probe 4 is set;

[0046] The detection position of the Gaussmeter probe 4 on the magnetized magnet is set by the trigger parameter, and the second power unit and the third power unit drive the Gaussmeter probe 4 to move to the detection position by the trigger parameter;

[0049] The trigger parameters set by the user are corrected by the correction parameters. The trigger parameters set by the user have error values, and the error values ​​are difficult to observe with the naked eye.

[0050] Since there is a deviation in the Gauss value at each position of the magnetized magnet, due to the existence of the error value, the data detected by the Gauss meter probe 4 when detecting the Gauss value of the magnetized magnet is inaccurate, thereby causing inaccurate determination of the Gauss value;

[0053] The correction parameters include an X-axis value and a Y-axis value. The X-axis value ranges from 1% to 3% of the width of the magnetized magnet, and the Y-axis value ranges from 1% to 3% of the length of the magnetized magnet.

[0054] It also includes a plurality of measuring light curtains and a spiral elevator, the spiral elevator is fixedly connected to the measuring light curtain, the controller 7 obtains the height position of each magnetized magnet through the measuring light curtain, and controls the downward movement distance of the Gauss meter probe 4. When the magnetized magnet is placed manually, the magnetized magnet may be tilted in the hole, so that the magnetized magnet will slightly protrude from the hole, resulting in different spacing distances between the magnetized magnet and the Gauss meter probe 4;

[0055] The measuring light curtain includes a transmitting end and a receiving end. Both the transmitting end and the receiving end are provided with a spiral elevator and rise and fall synchronously. Two measuring light curtains are provided on the side of the table 1, and the two measuring light curtains are vertically arranged.

[0056] The magnetized magnets protruding from the hole are screened out, and the protruding distance is obtained. The controller 7 controls the downward movement distance of the Gaussmeter probe 4 when on the hole through the protruding distance to prevent the resistance force between the Gaussmeter probe 4 and the magnetized magnet from being too large, thereby damaging the Gaussmeter probe 4.

[0057] A camera is fixedly connected to the fixing member 3, and the camera is used to image the magnetized magnet. The controller forms the outer contour of the magnetized magnet according to the imaging, and generates the dimension data of the outer contour, wherein the dimension data at least includes the length value and the width value. The controller changes the X-axis value and the Y-axis value in the correction data according to the dimension data.
