[0002] Irradiation processing using electron beams generated by industrial electron accelerators has become a crucial process in the chemical, power, agricultural and sideline products, and environmental protection industries. The electron gun in the accelerator is controlled by a power supply that controls the beam current. This power supply control must account for the complex electromagnetic environment within the accelerator cylinder. Photoelectric sensing is used to collect signals and control the power supply to draw voltage from the power coil.
[0003] However, light emission is scattered, especially in a mirrored loop between the light-emitting diode and the photodiode. Without limiting or preventing interference, the photodiode can be easily affected by the light from the loop's light-emitting diode, leading to inaccurate responses. Furthermore, if the relative positions of the light-emitting diode and the photodiode are not properly aligned, the photodiode's active and accurate response cannot be guaranteed.

DETAILED DESCRIPTION
[0015] Example 1
[0016] like Figure 1 As shown, the present embodiment proposes an anti-interference and adjustment device for a light-emitting photodiode, which includes a diode position adjustment plate 6 , a power diode mounting plate 10 , an anti-interference component and a substrate 3 .
[0017] The active light emitting diode 5 and the loop photodiode 13 are mounted side by side on the diode position adjustment plate 6. The photodiode 11 and the loop light emitting diode 12 are mounted side by side on the power diode mounting plate 10, and the spacing between the active light emitting diode 5 and the loop photodiode 13 is equal to the spacing between the photodiode 11 and the loop light emitting diode 12.
[0018] Two sets of anti-interference components are installed on the diode position adjustment plate 6 and the power diode mounting plate 10, respectively. Each set has a storage space inside and an opening at the outer end. The active LED 5, loop photodiode 13, photodiode 11, and loop LED 12 are located inside the storage space of the four sets of anti-interference components and face the four openings, allowing them to transmit and receive light beams normally.
[0019] The base 3 is provided with an adjustment component for adjusting the position of the diode position adjustment plate 6 to align the active LED 5 with the photodiode 11 and the loop photodiode 13 with the loop LED 12. The optical path from the active LED 5 to the photodiode 11 is the signal transmission path, while the optical path from the loop LED 12 to the loop photodiode 13 is the signal reception path.
[0020] The anti-interference assembly includes a focusing tube 7 and a protective cover 8 positioned around the focusing tube 7. The opening is located at the outer end of the protective cover 8, and the focusing tube 7 faces the opening. The four focusing tubes 7 are located outside the active LED 5, the loop photodiode 13, the photodiode 11, and the loop LED 12, respectively. The outer ends of the focusing tubes 7 are open, enabling precise focusing.
[0021] The focusing tube 7 is a cylindrical structure, and the protective cover 8 is a cylindrical structure. The focusing tube 7 and the protective cover 8 are coaxially distributed to ensure the overall structure is regular and improve the anti-interference effect of light.
[0022] This embodiment shields the diodes with anti-interference components to prevent interference from the mirrored loop LEDs. Four sets of anti-interference components enclose the active LED 5, loop photodiode 13, photodiode 11, and loop LED 12, respectively, leaving openings exposed to ensure that each diode transmits / receives light through its corresponding opening. Adjustment components align the diodes, aligning the active LED 5 with the photodiode 11 and the loop photodiode 13 with the loop LED 12. This ensures diode response accuracy, enabling precise control of the electron gun's power supply, and precisely controlling the accelerator's electron beam current, thereby maintaining stable accelerator operating conditions and energy efficiency.
[0023] Example 2
[0024] like Figure 1As shown, this embodiment proposes an anti-interference and adjustment device for a light-emitting photodiode. Compared to the first embodiment, the adjustment assembly in this embodiment includes a ball seat 14 disposed on a base 3, a universal ball joint 2 spherically hinged on the ball seat 14, a stud 4 welded to the universal ball joint 2, a fixing nut 9 threadedly connected to secure the stud 4 to the diode position adjustment plate 6, and a set screw 1 threaded onto the ball seat 14 and secured by abutting the universal ball joint 2 with its end. When adjusting the active light-emitting diode 5 and the loop photodiode 13, the set screw 1 is first loosened, and the diode position adjustment plate 6 is rotated, causing the universal ball joint 2 to rotate on the ball seat 14. When the active light-emitting diode 5 is aligned with the photodiode 11, and the loop photodiode 13 is aligned with the loop light-emitting diode 12, the set screw 1 is tightened, and the end of the set screw 1 abuts against the universal ball joint 2 for tightening. The adjustment process is very simple and convenient.
[0025] The diode position adjustment plate 6 has a through-hole for the stud 4 to pass through. The stud 4 has an outer convex ring portion that abuts the diode position adjustment plate 6. The outer diameter of the outer convex ring portion is larger than the diameter of the through-hole. When installing the diode position adjustment plate 6, the stud 4 is inserted through the through-hole on the diode position adjustment plate 6. The diode position adjustment plate 6 abuts the outer convex ring portion of the stud 4. Then, a fixing nut 9 is screwed onto the outer end of the stud 4 and crimped onto the diode position adjustment plate 6 to tighten it.
[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
