6results about How to "Reduce transmission error" patented technology

The utility model discloses an electronic pressure switch, which is applied to the technical field of pressure switches, and comprises a switch main body and a joint, a support frame is arranged in the switch main body, a circuit board is bolted in the support frame, one end of the support frame far away from the joint is in interference fit with a silica gel pad, and the silica gel pad is connected with the circuit board. Two keys used in cooperation with the circuit board are symmetrically inserted in the side, away from the connector, of the switch body, and an induction core electrically connected with the circuit board is clamped in the connector. Pressure is sensed and measured through the sensing core body, and the pressure sensed by the sensing core body is finely measured through the circuit board, so that the pressure is fed back to the plug-in unit and is converted into an electric signal to be fed back to the plug-in unit, and the plug-in unit can transmit the electric signal outwards to drive the switch to be switched on and off. The sensing precision of the pressure switch is improved, and transmission errors are reduced. And the action is triggered directly through an electric signal without a mechanical moving part, so that quick response can be realized, and the practicability is improved.

A wafer ring cutting device, comprising: an operation table, the operation table having a wafer mounting position and a supporting shaft, and a wafer to be processed having a first surface and a second surface opposite to each other; a cutting platform, the cutting platform being arranged on the first surface and being adapted to cut a supporting ring on the wafer to be processed; and a UV irradiation platform, the UV irradiation platform being arranged on the supporting shaft on the second surface, and the center of the cutting platform and the center of the UV irradiation platform being concentric in a direction perpendicular to the surface of the wafer to be processed.

A toothed chain transmission system, belonging to the field of chain drive technology, includes a toothed chain and sprockets that mesh with each other. The chain includes guide plates, toothed chain plates, pins, and rollers. Rollers are mounted on the pins. The guide plates are located on both sides of the chain, and the two ends of the pins are respectively interference-fitted with first connecting holes on the guide plates. The toothed chain plates include first toothed chain plates and second toothed chain plates. The first toothed chain plates are arranged side by side along the pin axis on two adjacent pins between adjacent guide plates. The second toothed chain plates are connected to two pins located on the inner side of the first toothed chain plates between adjacent first toothed chain plates. This invention is based on the meshing transmission principle of toothed chains and optimizes and improves the original toothed chain, thereby achieving the goals of noise reduction, load increase, and transmission efficiency improvement when used in conveying equipment, significantly improving the overall performance and reliability of the chain drive system.

This utility model relates to the field of mechanical engineering, and more particularly to a protection device for a gantry dual-drive synchronous motion system with adjustable margin. The dual-drive synchronous mechanism consists of two transmission mechanisms, each containing a dual-axis motor, lead screw, pulley, and belt, providing power to the crossbeam. The crossbeam moving mechanism includes a crossbeam and a base, with lead screws connected to both ends of the crossbeam. Position sensors are installed on the crossbeam to detect the relative height of the two ends to ensure synchronization. The protection mechanism includes a limiting component and a tensioning component. The tensioning component is used to adjust the tension of the transmission belt, achieving adjustable margin to adapt to different working conditions. The limiting component not only restricts the movement range of the synchronous pulley, but its limiting position is also adjustable, thereby setting the allowable working range margin of the synchronous pulley. This invention ensures the motion synchronization of the gantry system through position sensor feedback and dual margin adjustment, and improves the reliability and adaptability of the system by protecting key components through limiting.
