This utility model discloses a wafer support ring holder for proton irradiation of wafers, relating to wafer irradiation processing. It includes a wafer tray, which is the main tray. The top surface of the wafer tray has an irradiation width region, within which several wafer support rings are arranged. Each wafer support ring is circular, and adjacent wafer support rings are evenly spaced within the irradiation width region. The wafer tray is made of 5051 aluminum alloy. This utility model improves the wafer placement method by structurally adding support rings. Through welding fixtures, the center of the wafer is precisely aligned with the irradiation center, ensuring irradiation accuracy. This utility model optimizes the wafer handling operation by structurally designing the support rings as two-lobed pieces with a gap in the middle, facilitating alignment and flipping operations with a vacuum pen, reducing damage to the wafer during manual handling.

The utility model discloses a kind of circuit board punching device for circuit board cutting, including drill, drill rod of the drill is detachably connected with composite drill bit, the composite drill bit includes drill bit shell, the outer side wall middle position of the drill bit shell is equipped with several inner grooves in circumferential array distribution, the inside center of each the inner groove is fixedly connected with telescopic spring polishing rod, the telescopic spring polishing rod is jointly composed by tubular portion fixed in inner groove inside and rod-shaped portion connected in tubular portion inside by spring, and polishing sheet is provided on the tubular portion outside of the telescopic spring polishing rod. The utility model is driven by inner core to make one-way sliding block contract inwards, telescopic baffle expands to outside simultaneously, and then no longer blocks telescopic spring polishing rod, at this time telescopic spring polishing rod is subjected to centrifugal effect and then polishes the outside of hole wall, and telescopic spring polishing rod only extends after inner core is pressed, and then accurately positions the position of hole wall.

This invention relates to a dynamic optimization decision-making model for the mining sequence of polymetallic symbiotic ore bodies, comprising an edge layer, a cloud platform, and a control terminal. The edge layer, cloud platform, and control terminal interact through dedicated interfaces, achieving a closed-loop process from data acquisition, processing, decision-making, to execution. The edge layer acquires ore body data in real time via a multi-source sensor network, preprocesses it through an edge computing terminal, and then uploads it to the cloud platform. The cloud platform uses a dynamic geological model engine to construct a real-time 3D ore body model and generates a Pareto optimal mining scheme that comprehensively considers economic, environmental, and safety factors through a multi-objective optimization engine. The control terminal uses a digital twin console to visualize the scheme and allow for manual intervention, while the equipment control system automatically executes mining commands. The model supports hourly dynamic updates, significantly improving resource recovery rate and decision-making efficiency, reducing environmental costs and mining risks, and achieving efficient, intelligent, and green mining of polymetallic symbiotic ore bodies.
