Intelligent injection molding machine control system and method based on gram weights of injection molded products

Abstract

The invention discloses an intelligent injection molding machine control system based on the gram weights of an injection molded products. The intelligent injection molding machine control system comprises a manipulator; the manipulator is provided with a pick-up module; the pick-up module is provided with a plurality of pick-up measurement units; the pick-up measurement units are used for pick-up fixation and gravity measurement of the injection molded products; the manipulator is connected with a conveying module; and the conveying module is used for screening and conveying the injection molded products according to the measured and calculated gram weights of the injection molding products. The invention further discloses an intelligent injection molding machine control method based on the gram weights of the injection molding products. The method comprises the steps of: calling related data of no-load and standard parts; carrying out pick-up and data measurement of injection molded parts; carrying out data calculation and detection; and screening and conveying the injection molded parts. According to the invention, by directly combining a gravity sensor and a force sensor on the manipulator, the manipulator completes gram weight detection of the injection molded parts in the process of transferring the injection molded part from a die to a conveying device, the time for separately carrying out gram weight detection is saved, and the working efficiency is improved.

Description

Technical field [0001] The present invention relates to an injection molding machine, and more particularly relates to an intelligent control system and method for an injection molding machine for plastic injection molded product gram weight. Background technique [0002] Mainly by injection molding of plastic products production process, the injection molding machine is a major production equipment. A typical injection molding process includes the following six steps: mold clamping, injection, dwell, cooling, mold opening, ejection, ejection after gripping by the robot conveyor placed into injection molded product uploaded to the specified location. In the injection molding process, since a variety of random and unexpected factors that happens after the injection molded product is not exactly the same, the main difference is that the injection-molded products because of the different densities of material results in weight distribution are not identical, or weight differences in...

Problems solved by technology

[0004] The present invention is to overcome the need for an independent measuring tool in the prior art to measure the gram weight of the injection molded product, so that it is necessary to increase the step of transferring to the measuring tool and then transferring to the conveyor belt during the process of grabbing the injection molded part by the manipulator and transferring it to the conveyor belt. The shortcoming of the transfer time of injection molded parts provides an intelligent injection molding machine control system and method based on the weight of injection molded products. By directly combining gravity sensors and force sensors on the manipulator, the manipulator can transfer the injection molded parts from the mold to the conveyor. The gram weight detection of injection molded parts is completed during the installation process, which saves the time for separate gram weight detection and improves work efficiency
