Common motor-based low-cost energy-saving injection molding robot and control method thereof

Abstract

The invention discloses a common motor-based low-cost energy-saving injection molding robot and a control method thereof. The robot comprises an injection molding machine body comprising an oil pump motor, a mechanical arm arranged on the injection molding machine body and a mechanical arm control system arranged on the injection molding machine body for controlling the mechanical arm, wherein the mechanical arm control system performs signal transmission through a first terminal block and a second terminal block which are connected in series. The method comprises: a starting and stopping step, a clamping step, a backward pulling step, a screwing out step, a chamfering step, a loosening step, a backward adjusting step, a screwing step and a forward pull step. The oil pump motor is a common motor; more than one third of energy is saved by adopting a cooling shut-down method; and the energy-saving effect is better by combining the properties of the common motor. Besides, the connection problem is solved with fewest wires through the connection mode of the terminal blocks.

Description

technical field [0001] The invention relates to an injection molding robot and a control method thereof, in particular to a low-cost energy-saving injection molding robot based on a common motor and a control method thereof. technical background [0002] In the prior art, there are many solutions to the energy-saving problem of injection molding machines. Energy-saving effects can be achieved by controlling analog quantities or changing the mechanical structure, such as the energy-saving control system disclosed in the patent application number 200710069994.2. By controlling the pressure And the flow rate achieves the effect of saving energy, but the amount of measurement and calculation is large, and the control method is cumbersome; for example, the patent application number 01137653.8 discloses an energy-saving frequency converter for injection molding machines and an energy-saving method. To control the speed of the motor of the injection molding machine to achieve the e...
