The application discloses a semiconductor flat-plate warehouse inserting and taking structure, which comprises an inserting and taking connecting frame, an inserting and taking arm and a self-adapting locking mechanism arranged on the inserting and taking arm. The self-adapting locking mechanism mainly comprises a straight-line transmission rod, a scissor type lifting amplification mechanism, a limiting pressing plate and a guiding reset unit. The core of the application is that the self-weight load generated during the inserting and taking of the flat-plate warehouse is used as a driving force. When the inserting and taking arm supports the flat-plate warehouse, the weight presses the straight-line transmission rod, forces the scissor type lifting mechanism to expand and drives the limiting pressing plate to stably move downwards, so that the positioning pin on the limiting pressing plate is inserted into the pin hole of the flat-plate warehouse, automatic locking and positioning are realized. After unloading, the mechanism is automatically reset under the action of the reset spring. The application does not need external power, realizes "inserting and taking to locking", can effectively inhibit the inertial swing and vibration during the carrying process, prevents the wafers in the warehouse from being damaged due to knocking and has the advantages of simple structure, reliability, safety and high positioning precision.

The application relates to a vacuum smelting furnace feeding lifting mechanism, which comprises a feeding chamber and a lifting device arranged at the upper end in the feeding chamber. The lifting device comprises an electric hoist, the electric hoist is provided with a chain, the end of the chain is provided with a hook, the inner side wall of the feeding chamber is provided with a rectangular frame, the rectangular frame is internally provided with a horizontally-sliding mounting rack, the front end of the mounting rack is provided with a guide plate, the outer side of the rectangular frame is provided with a horizontal moving mechanism for driving the mounting rack to horizontally move, the guide plate is provided with a through hole for the chain to pass through, and the hook is located below the guide plate. Through the combined motion of horizontal movement and vertical lifting, the hook is actively deviated from the position directly below the lifting lug, and manual pulling of the inclined hook is not needed.

This utility model discloses a circular die-cutting machine, relating to the technical field of circular die-cutting machines. It includes a fixed plate, a circular die-cutting assembly on the top of the fixed plate, a gantry frame on the top of the fixed plate, and a fixed shell on the surface of the gantry frame. Limiting mechanisms for preventing material deviation on the left and right sides are provided on the gantry frame and the fixed shell. Two clamping mechanisms for clamping the material on the upper and lower sides to prevent jumping are provided on the limiting mechanisms. Each limiting mechanism includes a limiting shaft rotatably mounted on the gantry frame. A gear is fixedly mounted at the bottom end of the limiting shaft. Two moving rods are slidably mounted on the inner wall of the fixed shell. A toothed rod is fixedly mounted on the surface of each of the two moving rods, and the two toothed rods mesh with the gear. This utility model achieves positioning and correction for materials of various widths and thicknesses, offering high flexibility, good correction effect, improved die-cutting accuracy, simple operation, and strong practicality.

This invention discloses a drone lifting and locking mechanism, system, and docking control method. It includes a suspension device and a locking seat. The suspension device comprises a suspension section with a suspension seat at its top. A positioning seat is mounted on the lower side of the suspension section via multiple connecting rods. Half-gears are rotatably mounted on the connecting rods. A driver is mounted on the suspension section, and a drive gear is mounted on the output shaft of the driver, simultaneously meshing with each half-gear. A groove is provided in the middle of the upper side of the locking seat to mate with the positioning seat, and an annular groove is provided within the groove. When the driver drives each half-gear to rotate, a portion of the half-gear extends out of the positioning seat and inserts into the annular groove. This connects and locks the suspension device to the locking seat, eliminating the need for manual hooking or binding when docking the drone with cargo, making docking more convenient and reducing safety risks.
