This utility model relates to the field of agricultural technology, specifically to a laser weeding machine, including a power supply, a mechanical mounting structure, a system main control unit, functional modules, a motor and its drive module. The functional modules are characterized by comprising a sub-control module, a characteristic spectrum storage chip, a spectrometer, a spectrometer light source, an optical path coupling module, and a laser. This utility model utilizes a right-angle prism to reflect the light emitted from the spectrometer light source and the laser from opposite directions, respectively. A stepper motor can precisely adjust the angle of the right-angle prism, ensuring that the two beams of light from the spectrometer light source and the laser can be focused on almost identical small areas. This improves the accuracy of beam positioning, enhances the reliability and efficiency of the system, and avoids the complex and expensive dichroic mirrors required in traditional laser weeding equipment, thus greatly simplifying the structure of the optical system and reducing production costs and technical implementation difficulties.

The present invention provides a method for preparing an E-type iron core, comprising the following steps: S1, designing an E-type iron core model; S2, 3D printing the E-type iron core: using 3D printing technology to print an integrally formed E-type iron core, wherein the E-type iron core comprises a plurality of E-type iron sheets and a spacer layer, the spacer layer is arranged between two adjacent E-type iron sheets, and the spacer layer is composed of a plurality of triangular support blocks; S3, hot isostatic pressing; S4, sandblasting and polishing; S5, coating with an insulating solution; S6, solidification and molding. The preparation method realizes the preparation of the E-type iron core by three-dimensional printing. The preparation method can not only realize one-to-one precise molding of various complex structures according to the three-dimensional design size of the E-type iron core, but also has low operating technical difficulty, fewer operating process steps, simpler equipment and low price. At the same time, the E-type iron core can be integrally formed, thereby avoiding the problem of brittle fracture of iron sheets prepared by conventional stamping methods.

The present application relates to a webpage security control method and its device, equipment, medium, and product, the method comprising: displaying a target webpage, starting a pre-installed monitoring module therein; obtaining terminal feature data corresponding to the target webpage by the monitoring module; responding to a specific operation event triggered in the target webpage, submitting the terminal feature data to a risk control server, so that the risk control server determines the operator type of the target webpage according to the terminal feature data and returns a communication token assigned to the target webpage; after obtaining the communication token, submitting it and the business data of the specific operation event to the business server, so that the business server queries the risk control server for the operator type of the target webpage holding the communication token and processes the business data according to the operator type. The present application decouples the identification of the operator type of the operation event on the target webpage from the processing of the business data, and processes the business data according to the operator type, which can ensure that the data communication process is more secure.
