technical field

The invention relates to the technical field of vibration feeding control, in particular to an automatic precision weighing feeding controller based on the application of a vibration plate.

Background technique

The automatic feeding vibrating plate is a kind of feeding equipment with automatic orientation and sorting. Its working purpose is to automatically and orderly arrange the disordered workpieces neatly and accurately through vibration to transport them to the next process. The vibrating plate is an auxiliary equipment for automatic assembly machinery, which can discharge various products in an orderly manner. It can cooperate with automatic assembly equipment to assemble various parts of the product into a complete product. The automatic feeding vibrating plate is mainly composed of hopper, chassis, controller, linear feeder and other supporting components. There is a pulse electromagnet under the hopper of the automatic feeding vibrating plate, which can make the hopper vibrate in the vertical direction. Due to the inclination of the spring piece, the hopper makes torsional vibration around its vertical axis. Due to this vibration, the parts in the hopper rise along the spiral track until they are sent to the discharge port.

At present, in order to realize the weighing function of production equipment, all of them are realized through the combination of high-precision A/D converter + PLC (computing unit) + feeding controller, the cost is too high, and because of the integration of the control system itself, it seriously affects the overall equipment performance.
