Pressure Regulating Vibration Plate Controller

Abstract

The invention provides a voltage regulating type vibration disc controller. The voltage regulating type vibration disc controller comprises a regulating speed signal output module, a pulse triggering generating circuit, a silicon controlled rectifier triggering circuit, a peak detection circuit and a comparator. According to the voltage regulating type vibration disc controller, the peak detection circuit is arranged at the output end of the silicon controlled rectifier triggering circuit, the average output voltage of the silicon controlled rectifier triggering circuit is detected through the peak detection circuit and compared with an output signal of the regulating speed signal output module, accordingly, a closed loop control system can be formed, and under the situation, when the weight of materials on a vibration disc changes or interferes with external force, stable running of the vibration disk can still be guaranteed. Meanwhile, the controller is further provided with a phase synchronous circuit, the triggering angle of the triggering pulse can be accurately controlled through the phase synchronous circuit, the positive half-cycle amplitude and the negative half-cycle amplitude of the voltage obtained through triggering can be consistent, and the amplitude is stable.

Description

technical field [0001] The invention relates to a feeding vibrating plate, in particular to a pressure regulating controller for the vibrating plate. Background technique [0002] The vibrating plate is an auxiliary feeding device for automatic assembly or automatic processing machinery. It can arrange various products in an orderly manner, cooperate with automatic assembly equipment to assemble all parts of the product into a complete product, or cooperate with automatic processing machinery to complete the processing of workpieces. There is a pulse electromagnet under the vibrating tray, which can make the tray vibrate vertically or left and right, and the inclined spring plate drives the hopper to vibrate around its vertical axis. The parts in the hopper rise along the spiral track due to this vibration. After a series of orbital screening or posture changes during the ascent process, the parts can automatically enter the assembly or processing position in a unified sta...

Problems solved by technology

In the prior art, these two driving methods belong to open-loop control. The increase or decrease of materials and the change of external force will affect the feeding speed, which cannot achieve good speed regulation and stable speed performance.
