[0024] In order to make the technical problems, technical solutions, and beneficial effects of the present application clearer, the present application will be described in detail in conjunction with the accompanying drawings. The figure is a simplified schematic diagram, and only illustrates the basic concept of the present application in a schematic manner, so it only shows the relevant components of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] As shown in Figure 1 The present embodiment provides a magnetic clamp control circuit 100, which includes a power supply circuit unit 1, a control circuit unit 2, and a load circuit unit 3.

[0026] In some embodiments, the output end of the power supply circuit unit 1 is electrically connected to the input end of the control circuit unit 2, and the output end of the control circuit unit 2 is electrically connected to the input end of the load circuit unit 3. Among them, the power supply circuit unit 1 is used to provide stable and adaptive power for the magnetic clamp control circuit through reasonable voltage conversion and adjustment, to ensure the normal operation of the equipment and realize precise control. The control circuit unit 2 is used to realize precise control of the magnetic coil voltage and power on-off, so as to meet the operation requirements of the imaging detection aperture equipment in different working scenarios, and improve the operation convenience and safety of the equipment. The load circuit unit 3 is used to fix the magnetic mold by generating a magnetic field, so as to ensure that the imaging detection aperture equipment can normally and accurately perform detection work.

[0027] As shown in Figure 2As shown, in some embodiments, the power supply circuit unit 1 includes a first switch 11, a switching power supply 12 and a DC-DC step-down module 13. The output of the first switch 11 is electrically connected to the input of the switching power supply 12, and the output of the switching power supply 12 is electrically connected to the input of the DC-DC step-down module 13. The first switch 11 is located on the AC 220V input line, and the first switch 11 functions as a power supply master switch. When the first switch 11 is closed, the AC 220V power supply can enter the subsequent switching power supply 12 for conversion, thereby powering the entire circuit; when the first switch 11 is open, the entire circuit will be powered off, and no current will pass through the subsequent electronic components. The first switch 11 is very important when the equipment is maintained, repaired or not used for a long time. By opening the first switch 11, the safety of the operator during operation can be ensured, and accidental electric shock and other situations can be prevented. At the same time, unnecessary power consumption of the equipment in the non-working state can also be avoided. The switching power supply 12 converts the input AC 220V alternating current into DC 24V direct current, as most of the electronic components in the subsequent circuit require direct current to work normally. As an example, the DC-DC step-down module 13 and the load circuit unit 3 require stable direct current power. The DC-DC step-down module 13 is used for voltage regulation. The DC 24V output from the switching power supply 12 enters the DC-DC step-down module 13, which can adjust the output voltage within the range of 0-24V. By adjusting the voltage, the current supplied to the load circuit unit 3 can be accurately controlled, and the magnetic attraction generated by the load circuit unit 3 can be adjusted. Since in actual operation, it may be necessary to adjust the magnetic attraction of the load circuit unit 3 according to different detection requirements and die types, the DC-DC step-down module 13 provides the ability to flexibly adjust, so that the equipment can adapt to various working scenarios.

[0028] In some embodiments, the control circuit unit 2 includes an adjustable potentiometer 21 and a knob switch 22. The adjustable potentiometer 21 is electrically connected to the DC-DC step-down module 13.

The knob switch 22 is electrically connected to the DC-DC step-down module 13, and the knob switch 22 is used to control the on-off of the magnetic coil power supply. When the knob switch 22 is closed, current can pass through the load circuit unit 3, causing it to generate a magnetic field; when the knob switch 22 is open, the load circuit unit 3 is powered off and the magnetic field disappears.

[0029] In some embodiments, the load circuit unit 3 includes a magnetic coil 31, and the load of the magnetic coil 31 is 120Ω.
