Problems solved by technology

However, because the product is not a regular object when it falls, the detection signal of the electric eye may not be triggered during the falling process, so that the injection molding machine thinks that the product has not fallen, so the false alarm stops the automatic injection molding process,

Abstract

The invention relates to a mechanical-vision-based injection molding machine mold protecting system, which comprises a master control board using an embedded chip, a camera, a near infrared light source and a magnetic fixed seat, wherein the master control board is connected with an injection molding machine through an input/output (I/O) signal interface and connected with the camera through the camera interface; the camera and the near infrared light source are arranged on the magnetic fixed seat; and the magnetic fixed seat is arranged around the injection molding machine, so that the camera can acquire an image in the mold after the injection molding machine mold is opened under the near infrared light source. The invention also relates to a mechanical-vision-based injection molding machine mold protecting method, which comprises the following steps of: judging whether a product is qualified by using the camera, shooting the mold again after blanking, judging whether the blanking is successful, and giving a detection result signal. The blanking condition is judged directly through the mold image acquired by the camera, and the un-falling residual product in the mold is intelligently analyzed, so that the method is quite reliable and the mold is safer.

Description

technical field [0001] The invention relates to the technical field of injection molding machine mold protection, in particular to a machine vision-based injection molding machine mold protection system and method. Background technique [0002] Most plastic products in the world today are injection molded, and the production tools for injection molded products are injection molding machines and molds. The model of the injection molding machine only determines the size of the product that can be produced, and the injection mold really affects the appearance and shape of the product. In a complete set of injection molding equipment, although the mold occupies a small volume, the price is very expensive. [0003] Most of the injection molding machines on the market today do not carry out safety inspection and protection of the mold during the production of plastic products. In the fully automatic injection molding process, it is usually the end of a complete injection molding...
