Intelligent injection molding on-line visual inspection system

Abstract

The invention discloses an intelligent injection molding on-line visual inspection system including an injection molding machine, a weight type metering instrument, a plurality of cameras, a weighingsystem and a controller. The injection molding machine is provided with a feeding pipe, and the feeding pipe communicates with a hopper; the weight type metering instrument is arranged in the hopper;the injection molding machine is internally provided with a control manipulator, a driving motor, an injection molding mold and a weighing system; the plurality of cameras are arranged on the controlmanipulator respectively; the controller is mounted outside the injection molding machine. The system is simple in structure principle, convenient to use and high in intelligence degree, can realize the inspection control of the quality of products, traces the results of weighing and metering of a material, achieves contrast and linear relation calibration on the finished product after injection molding and metering data, monitors the injection-molded product quality, material usage amount, product weight and injection molding period of the injection molding machine in real time, and providesoriginal and accurate production large data for managers or customers.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to an intelligent online visual inspection system for injection molding. Background technique [0002] After nearly 20 years of rapid development in China, plastic injection molding has encountered a substantial increase in the cost of sites, personnel, and materials, making it difficult for secondary OEMs in the general field to survive. How can first-line OEMs effectively monitor and control production? The process has become particularly urgent, because the profits of the injection molding industry are getting thinner and thinner, but China's current situation is in the transition stage from the OEM type to the brand type. [0003] As an enterprise, the cost of the site is uncontrollable. From the perspective of the manufacturing environment and the national environmental protection policy, the cost of renting and buying land will become higher and higher; the cost of p...

Problems solved by technology

[0004] Traditional injection molding production must be in a controllable and predictable production mode in order to continue the production competitiveness of the enterprise; at present, the equipment in the injection molding industry is single-working, and can only be practical and work with a single equipment, such as the mold monitor. It can only monitor the safety of the mold, the gravimetric meter can only weigh the material, the injection molding machine can only inject the product, etc. The work of each device is just a simple PLC signal connection with the next device, and there is no such thing as Information interaction and closed-loop control, unable to monitor and control in real time
