[0046] Reference Figure 1 , Figure 1 This is a module diagram of the first embodiment of the soft X-ray auxiliary circuit proposed in this application. Figure 1 The first embodiment of the soft X-ray auxiliary circuit of the present application is proposed.

[0047] The soft X-ray auxiliary circuit is applied to a soft X-ray static eliminator; the soft X-ray auxiliary circuit comprises: a high voltage auxiliary branch 100 and a filament current auxiliary branch 200;

[0048] The high voltage auxiliary branch 100 connects the first transformer 300 and the filament current auxiliary branch 200 of the soft X-ray static eliminator for generating high voltage; the filament current auxiliary branch 200 connects the second transformer 400 of the soft X-ray static eliminator for generating current; the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 are also connected to the soft X-ray emission head 500 of the soft X-ray static eliminator for generating soft X-rays.

[0049] It should be understood that the soft X-ray auxiliary circuit includes a high voltage auxiliary branch 100 and a filament current auxiliary branch 200. The high voltage auxiliary branch 100 connects the first transformer 300 for generating high voltage and the filament current auxiliary branch 200 in the soft X-ray static eliminator, and is also connected to the soft X-ray emission head 500. The filament current auxiliary branch 200 connects the second transformer 400 for generating current in the soft X-ray static eliminator, and is also connected to the soft X-ray emission head 500. The auxiliary circuit is a part of the soft X-ray static eliminator, and performs its auxiliary function by connecting with the transformers (the first transformer 300 and the second transformer 400) in the soft X-ray static eliminator and the soft X-ray emission head 500.

[0050] The filament current auxiliary branch 200 is used to adjust the current generated by the first transformer 300 to a filament current, and transmit the filament current to the soft X-ray emission head 500 to assist the soft X-ray emission head 500 in forming an electron beam.

[0051] It should be noted that one of the main functions of the filament current auxiliary branch 200 is to regulate the current. It receives the current generated by the first transformer 300 and regulates it to the filament current. The regulated filament current is transmitted to the soft X-ray emission head 500, and this process assists the soft X-ray emission head 500 in forming an electron beam. The formation of an electron beam is an important link in the soft X-ray generation process.

[0052] The high voltage auxiliary branch 100 is used to stabilize the high voltage generated by the first transformer 300 to generate a target voltage, and transmit the target voltage to the soft X-ray transmitting head 500 to assist the soft X-ray transmitting head 500 in generating soft X-rays.

[0053] It should be understood that the high voltage auxiliary branch 100 stabilizes the high voltage generated by the first transformer 300. This step ensures the stability of the voltage. The target voltage generated after the voltage stabilization is transmitted to the soft X-ray emission head 500 to assist the soft X-ray emission head 500 in forming soft X-rays. By providing a stable target voltage, the soft X-ray emission head 500 can work normally to generate soft X-rays, thereby playing a corresponding role in the soft X-ray static eliminator.

[0054] In this embodiment, the soft X-ray auxiliary circuit is applied to a soft X-ray static eliminator; the soft X-ray auxiliary circuit comprises: a high voltage auxiliary branch 100 and a filament current auxiliary branch 200; the high voltage auxiliary branch 100 is connected to a first transformer 300 for generating high voltage and the filament current auxiliary branch 200 of the soft X-ray static eliminator; the filament current auxiliary branch 200 is connected to a second transformer 400 for generating current of the soft X-ray static eliminator; the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 are also connected to a second transformer 400 for generating current of the soft X-ray static eliminator; The soft X-ray emission head 500 is used to generate soft X-rays; the filament current auxiliary branch 200 is used to adjust the current generated by the first transformer 300 to the filament current, and transmit the filament current to the soft X-ray emission head 500 to assist the soft X-ray emission head 500 in forming an electron beam; the high voltage auxiliary branch 100 is used to stabilize the high voltage generated by the first transformer 300 to generate a target voltage, and transmit the target voltage to the soft X-ray emission head 500 to assist the soft X-ray emission head 500 in forming soft X-rays, so that the soft X-rays have stronger energy and better stability.

[0055] Reference Figure 2 , Figure 2 This is a module schematic diagram of the second embodiment of the soft X-ray auxiliary circuit proposed in the present application. Based on the first embodiment of the soft X-ray auxiliary circuit mentioned above, the second embodiment of the soft X-ray auxiliary circuit of the present application is proposed.

[0056] The high voltage auxiliary branch 100 includes: a first driving module 110, a first power conversion module 120 and a first half-bridge circuit 130;

[0057] The first power conversion module 120 is respectively connected to the first driving module 110 and the first half-bridge circuit 130 ; the first driving module 110 is also connected to the first transformer 300 ; the first half-bridge circuit 130 is also connected to the soft X-ray emission head 500 .

[0058] It should be understood that the first power conversion module 120 acts as a bridge connecting the first driving module 110 and the first half-bridge circuit 130, so that electric energy can be effectively transferred between the two modules. The first driving module 110 is connected to the first transformer 300, and this connection enables it to receive the high voltage generated by the first transformer 300. At the same time, it is also connected to the first power conversion module 120 to provide a driving voltage for it. The first half-bridge circuit 130 is not only connected to the first power conversion module 120, but also connected to the soft X-ray emission head 500, and is the last link to transmit the processed voltage to the soft X-ray emission head 500.

[0059] The first driving module 110 is used to receive the high voltage generated by the first transformer 300 and provide a driving voltage for the first power conversion module 120 .

[0060] It should be noted that the main function of the first driving module 110 is to receive the high voltage from the first transformer 300. The transformer is an electrical device that can change the voltage. The high voltage generated by the first transformer 300 is received by the first driving module 110. Then, the first driving module 110 provides the driving voltage to the first power conversion module 120. The driving voltage is like a starting signal or energy source, which provides the necessary conditions for the operation of the first power conversion module 120.

[0061] It should be noted that the chips U1 and U2 in the first power conversion module 120 may adopt AOZ1242AI, which is a step-down DCDC converter. Since the energy of soft X-rays is relatively low, the external voltage needs to be stepped down.

[0062] It should be understood that the first driving module 110 is composed of Q5 and R11, and provides an enable signal to U1 and U2 by turning on Q5.

[0063] Please note that, please refer to Figure 2 The pin interfaces of U1 and U2 from left to right and from top to bottom are the VIN, EN, COMP, VBIAS, LX, BST, FB, and GND pin interfaces of AOZ1242AI respectively.

[0064] The first power conversion module 120 is used to step down the driving voltage and transmit the step to the first half-bridge circuit 130 .

[0065] It should be understood that the task of this module is to step down the driving voltage provided by the first driving module 110. The step-down operation is to adjust the voltage to a level suitable for subsequent circuit processing or device use. The first power conversion module 120 transmits the stepped-down voltage to the first half-bridge circuit 130, thereby providing a suitable input voltage for the voltage processing of the next link.

[0066] The first half-bridge circuit 130 is used to stabilize the stepped-down driving voltage to generate a target voltage and transmit it to the soft X-ray emission head 500 .

[0067] It should be noted that the role of the first half-bridge circuit 130 in the entire circuit is to stabilize the driving voltage after the voltage reduction. Voltage stabilization is to ensure the stability of the voltage and avoid the adverse effects of voltage fluctuations on the soft X-ray emission head 500. After voltage stabilization, the first half-bridge circuit 130 will generate a target voltage, which is a voltage value specially designed for the soft X-ray emission head 500. Finally, this target voltage is transmitted to the soft X-ray emission head 500 to provide appropriate voltage support for the normal operation of the soft X-ray emission head 500.

[0068] The filament current auxiliary branch 200 includes: a second driving module 210, a second power conversion module 220 and a second half-bridge circuit 230;

[0069] The second power conversion module 220 is respectively connected to the second driving module 210 and the second half-bridge circuit 230; the second driving module 210 is also connected to the second transformer 400; the second half-bridge circuit 230 is also connected to the soft X-ray emission head 500;

[0070] The second driving module 210 is used to receive the current generated by the second transformer 400 and provide driving current for the second power conversion module 220 .

[0071] It should be noted that the second driving module 210 is in the starting link of the current in this auxiliary branch. Its main function is to receive the current generated by the second transformer 400, which is a source of the entire branch current. It also provides driving current for the second power conversion module 220 and is the current supplier for the normal operation of subsequent modules.

[0072] The second power conversion module 220 is used to receive the driving voltage, step down the voltage, and transmit the voltage to the second half-bridge circuit 230 , and also transmit the driving current to the second half-bridge circuit 230 .

[0073] It should be understood that, in terms of voltage, the second power conversion module 220 receives a driving voltage, which may be a voltage signal from an external power source or other parts of the circuit, and then performs a voltage reduction operation on it, and transmits the reduced voltage to the second half-bridge circuit 230. In terms of current, it also transmits the driving current received from the second driving module 210 to the second half-bridge circuit 230, playing a dual role of current transmission and voltage conversion.

[0074] The second half-bridge circuit 230 is used to stabilize the stepped-down driving voltage to generate the target voltage and adjust the driving current to be the filament current to be transmitted to the soft X-ray emission head 500 .

[0075] It should be noted that, for voltage, the second half-bridge circuit 230 performs a voltage stabilization operation on the stepped-down driving voltage to finally generate a target voltage. This target voltage may play a key role in the normal operation of the soft X-ray emission head 500, for example, providing a suitable voltage for the target material in the soft X-ray emission head 500 to generate soft X-rays. For current, it adjusts the driving current received from the second power conversion module 220, converts it into a filament current, and then transmits it to the soft X-ray emission head 500, providing a suitable current for the filament in the soft X-ray emission head 500, thereby ensuring the normal operation of the soft X-ray emission head 500.

[0076] It should be understood that the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 are both embedded in one side of the power conversion board 900 of the soft X-ray static eliminator.

[0077] In this embodiment, the filament current auxiliary branch 200 is used to adjust the current generated by the first transformer 300 to a filament current, and transmit the filament current to the soft X-ray transmitter head 500 to assist the soft X-ray transmitter head 500 in forming an electron beam; the high voltage auxiliary branch 100 is used to stabilize the high voltage generated by the first transformer 300 to generate a target voltage, and transmit the target voltage to the soft X-ray transmitter head 500 to assist the soft X-ray transmitter head 500 in forming soft X-rays, so that the soft X-ray energy is stronger, the stability is better, and the balance voltage is more stable.

[0078] Reference Figure 3 and Figure 4 , Figure 3 This is a first circuit connection diagram of the third embodiment of the soft X-ray auxiliary circuit proposed in this application. Figure 4 This is a second circuit connection diagram of the third embodiment of the soft X-ray auxiliary circuit proposed in this application. Based on the first and second embodiments of the soft X-ray auxiliary circuit mentioned above, the third embodiment of the soft X-ray auxiliary circuit of this application is proposed.

[0079] The soft X-ray auxiliary circuit further includes: a voltage doubling module 600;

[0080] The voltage doubling module 600 is embedded in one side of the voltage doubling plate 1000 of the soft X-ray static eliminator, and the voltage doubling module 600 is also connected to the high voltage auxiliary branch 100 and the soft X-ray emission head 500 respectively.

[0081] It should be noted that the voltage multiplier module 600 is embedded in one side of the voltage multiplier plate 1000 of the soft X-ray static eliminator. This indicates that it is physically closely integrated with the soft X-ray static eliminator, and the voltage multiplier plate 1000 may provide a certain physical support or electrical connection basis for the voltage multiplier module 600.

[0082] The voltage doubling module 600 is used to utilize the unidirectional conductivity of the diode and the charging characteristics of the capacitor to gradually multiply the target voltage and transmit the target voltage to the soft X-ray emission head 500 .

[0083] It should be understood that the voltage doubling module 600 works by utilizing the unidirectional conductivity of the diode and the charging characteristics of the capacitor. The unidirectional conductivity of the diode ensures that the current can only flow in a specific direction, thereby providing an orderly current path for the charging process of the capacitor. The charging characteristics of the capacitor enable it to store charge under the action of a suitable voltage. In this circuit, by cleverly utilizing the combination of diodes and capacitors, the voltage doubling module 600 can gradually multiply the input target voltage. After the voltage multiplication effect of the voltage doubling module 600, it transmits the final target voltage to the soft X-ray emission head 500. This transmission process is an important link for the soft X-ray emission head 500 to obtain a sufficiently high voltage to generate soft X-rays, because the generation of soft X-rays often requires specific high voltage conditions.

[0084] The soft X-ray auxiliary circuit further includes: an indication and control module 700;

[0085] The indication and control module 700 is embedded in one side of the MCU board 800 of the soft X-ray static eliminator;

[0086] The indication and control module 700 is used to adjust the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 according to pre-parameters or instructions, and indicate the generation status of soft X-rays.

[0087] It should be understood that U3 in the indication control module 700 may be PIC16F917-I / PT. For specific pin connections, see Figure 4 ; The module where U4 is located is used for voltage stabilization, its model may be UA78M33CDCYG3, and its pins from left to right and from top to bottom are INPUT, COM, and OUTPUT; the module where U5 is located is used for high-speed signal transmission, the model of U5 may be SN65HVD12DR, and its pins from left to right and from top to bottom are VCC, B, A, GND, R, RE anti-pin, DE, and D.

[0088] It should be noted that the indication control module 700 can adjust the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 according to the pre-parameters or instructions. This means that it can change the working state of the high voltage auxiliary branch 100 and the filament current auxiliary branch 200 according to the pre-set parameter values ​​(such as the limit values ​​of voltage and current, etc.) or external input instructions (which may come from the control system or the operator). For example, the voltage in the high voltage auxiliary branch 100 is adjusted according to the pre-parameters, or the current intensity in the filament current auxiliary branch 200 is changed according to the instructions, so as to ensure that the soft X-ray auxiliary circuit operates under appropriate working conditions.

[0089] It should be understood that the indication and control module 700 is also used to indicate the generation state of soft X-rays. This function is very critical because the generation state of soft X-rays may be difficult for the user to directly observe. The indication and control module 700 can inform the user whether soft X-rays are being generated, the intensity of the generation, or whether it is in a normal generation state in various ways, such as turning on and off the indicator light, displaying a specific mark on the screen, or outputting a specific signal, so as to facilitate the user to monitor and operate the entire soft X-ray generating device.

[0090] It should be noted that D26 emits blue light, D27 emits red light, and D28 emits green light.

[0091] The indication and control module 700 includes: an indication module 710 and a control module 720;

[0092] The control module 720 is connected to the indication module 710;

[0093] The control module 720 is used to analyze whether the target voltage value of the target voltage reaches a first preset value and whether the filament current value of the filament current reaches a second preset value, and control the indication module 710 to display different indication results according to different analysis results.

[0094] It should be noted that the control module 720 will instruct the indication module 710 to display different indication results. For example, if the target voltage value reaches the first preset value and the filament current value reaches the second preset value, the indication module 710 may display an indication indicating normal operation (such as a green light on); if the target voltage value does not reach the first preset value or the filament current value does not reach the second preset value, the indication module 710 may display a warning indication (such as a red light on or flashing, etc.). This design allows the user to intuitively understand the status of the target voltage and filament current in the system, so as to find problems in time or confirm the normal operation of the system.

[0095] In this embodiment, after the voltage multiplication by the voltage multiplier module 600, it transmits the final target voltage to the soft X-ray emission head 500. This transmission process is an important link for the soft X-ray emission head 500 to obtain a sufficiently high voltage to generate soft X-rays, because the generation of soft X-rays often requires specific high voltage conditions. If the target voltage value reaches the first preset value and the filament current value reaches the second preset value, the indication module 710 may display an indication indicating normal operation (such as a green light on); if the target voltage value does not reach the first preset value or the filament current value does not reach the second preset value, the indication module 710 may display a warning indication (such as a red light on or flashing, etc.).
