Embedded plastic mould protector based on histogram matching

Abstract

The invention relates to an embedded plastic mould protector based on histogram matching. The protector is divided into four modules including an image collection module, a calculating and matching module, a man-machine interaction module and an action control module, wherein the image collection module consists of two infrared cameras and one filament lamp, the calculation matching module comprises one Arm development board, the man-machine interaction module is an upper computer of an injection molding machine controller, the action control module is a lower computer of the injection molding machine controller; and the image collection module, the calculating and matching module and the man-machine interaction module are connected for control via Ethernet cables through a network hub, and the man-machine interaction module and the action control module are connected for control by a Can / 232 wire. The embedded plastic mould protector can automatically judge whether products without being demoulded stay in the plastic mould based on the difference of histograms of two images so as to protect the moulds effectively, and has the characteristics of high efficiency, high reliability, high safety coefficient and the like.

Description

technical field [0001] The invention relates to a plastic mold protection device, in particular to an embedded plastic mold protection device based on histogram matching, which belongs to the field of computer vision. Background technique [0002] Due to its excellent processing and use performance, plastics have been widely used in various fields of the national economy. At present, the total output of plastic products in my country has reached 30 million tons and is increasing year by year with a growth rate of 8% to 10%. Injection molding has become the most important production method in the plastics industry, especially high-performance plastic products, because of its good molding quality, high efficiency, and low cost. According to statistics, injection molded products account for about one-third of the total output of all molded plastic products, and injection molds account for more than half of the number of plastic molding molds. [0003] The injection mold consis...

Problems solved by technology

In addition to the high cost of manpower, this manual method has problems such as slow response speed and low reliability because the reaction time of normal people is 0.1-0.5s, and the concentration time is only 20-30 minutes.
