Problems solved by technology

[0003] (1) Due to the need to repeatedly operate the charging and demagnetizing equipment, the workload is heavy, the operation is complicated, and the efficiency is low;
[0004] (2) Due to human factors, different people have certain differences in the judgment of the final result, the device cannot reach the best state, and the consistency is poor;
[0005] (3) During the magnetic field debugging process, manual debugging basically does not record the corresponding performance data for each device, which is not conducive to device quality control and optimization

Embodiment 1

[0041] Embodiment 1: see figure 1 and figure 2 , an automatic and rapid debugging method suitable for the magnetic field of a surface-mounted circulator with lumped parameters, comprising the following steps:

[0042] (1) Build a control system for debugging the device to be debugged. The device to be debugged is a lumped parameter surface mount circulator. The control system includes a computer, a network analyzer, a mechanical arm, a charging and demagnetizing machine, a debugging fixture, And three placement positions, in which the network analyzer, the manipulator and the charging and demagnetizing machine are all connected to the computer;

[0043] The network analyzer is used to obtain the S parameter data of the device to be debugged and send it to the computer;

[0044] The mechanical arm is used to move the device to be debugged according to the control of the computer;

[0045] The charging and demagnetizing machine is used to generate different charging and dema...

Embodiment 2

[0061] Example 2: see figure 1 , this embodiment is further improved on the basis of Embodiment 1. After the step (4) obtains the S parameter data of the initial state of the device to be debugged, it also includes: judging whether the device to be debugged is connected to the debugging fixture normally according to the S parameter data , if it is not normal, reinstall the device to be debugged after manual inspection, and reacquire the S parameter data of the initial state until the connection is normal.

[0062] It also includes step (7) judging whether the control system needs to be shut down;

[0063] If shutdown is required, the charging and demagnetizing machine is reset to the initial voltage, the mechanical arm is controlled to a safe position, and the power is turned off;

[0064] If the system does not need to be shut down, repeat steps (4)-(6) to debug the next device to be debugged.

[0065] In the present invention, for the judgment of whether the performance in...

Abstract

The invention discloses a method suitable for automatic and quick debugging of the magnetic field of a surface-mounted circulator with lumped parameters, including (1) building a control system for debugging devices to be debugged, including a computer, a network analyzer connected to the computer, and a mechanical arm , a charging and demagnetizing machine, a debugging fixture, and three placement positions, the placement positions respectively correspond to the device disk to be debugged, the qualified device disk and the unqualified device disk; (2) control system startup detection; (3) control system reset, set The charging and demagnetizing machine is set to the demagnetization mode, and the mechanical arm is reset to the position of the device to be debugged; (4) Control the mechanical arm to take out a device to be debugged, install it on the debugging fixture, and obtain the S parameter data of the device to be debugged through the network analyzer; ( 5) Control the charging and demagnetizing machine to automatically adjust the voltage to adjust the magnetic field of the product; (6) Judge whether the product is qualified; (7) Sorting. The invention can realize the automatic debugging of the magnetic field of the device, greatly improves the efficiency, and makes the production more efficient and stable.

Description

technical field [0001] The invention relates to a debugging method, in particular to an automatic and fast debugging method suitable for the magnetic field of a surface-mounted circulator with lumped parameters. Background technique [0002] Microwave passive devices such as lumped parameter surface-mount circulators require magnetic field debugging to achieve the best performance. At present, the magnetic field debugging of the surface-mounted circulator with lumped parameters is basically carried out by manual charging and demagnetization, which has a large workload and low efficiency. performance at its best. And the artificial magnetic field debugging has the following deficiencies: [0003] (1) Due to the need to repeatedly operate the charging and demagnetizing equipment, the workload is heavy, the operation is complicated, and the efficiency is low; [0004] (2) Due to human factors, different people have certain differences in the judgment of the final result, the...
