Visual sense addressing location auto-filling equipment

Abstract

The invention relates to a visual addressing and positioning automatic filling equipment, which includes a frame, a conveying device, an automatic weighing device, a visual addressing device, a filling mechanism, and a central control device composed of a data processing unit and an automatic control unit; The weighing device includes an electronic scale connected to the bottom of the frame and a lifting mechanism fixed on the weighing platform. The bucket opening shielding plate is fixed on the weighing platform; The above support frame and the chuck assembly installed on the support frame; the visual addressing device includes a plane right angle positioning mechanism installed on the frame and an image collector and a spray gun bracket installed on the slider; the filling mechanism includes a feeding The telescopic spray gun is connected to the spray gun bracket, and the driving motor of the planar right-angle positioning mechanism, the image collector and the spray gun are connected to the central control device. The invention has the characteristics of little influence by environmental factors, accurate positioning of the mouth of the barrel, and reliable filling.

Description

technical field [0001] The invention relates to an automatic quantitative filling equipment for liquid products, in particular to an automatic filling equipment for visual addressing and positioning. Background technique [0002] Liquid quantitative filling equipment is a quantitative container packaging equipment that divides a large amount of bulk liquid materials into small loads of predetermined weight. Quantitative filling of traditional liquid products uses scales and is filled mechanically. During the filling process, the phenomenon of liquid materials being out of tolerance, running, popping, dripping, and leaking is very serious, and many liquid products will also endanger the health of operators. healthy. At present, a visual addressing and positioning automatic fixed-weight liquid metering and filling device is disclosed, including a body and a transmission mechanism set in the body, a weighing and measuring mechanism, a visual addressing and positioning mechanis...

AI Technical Summary

Problems solved by technology

However, the addressing and positioning device of this structure is to fix the electric eye on the top of the body, collect images through the electric eye after the filling barrel reaches the designated position, and judge the image collected by the electric eye to confirm the position of the barrel mouth, and the judgment is Based on the fact that the color difference of the image at the mouth of the filling barrel is much deeper than the color difference of the image on the surface of the filling barrel, the addressing and positioning of the above structure has the following defects: 1. The positioning of the mouth of the barrel is inaccurate

Since the image acquisition is a one-time fixed-point image acquisition of the position of the barrel mouth, after analyzing and comparing the collected images, the sliding pallet is controlled to move to the designated position, so in the process of moving to find the position of the barrel mouth, the generated by the sliding pallet The cumulative error cannot be corrected, so the positioning accuracy of the barrel mouth is not high

2. The range of image acquisition is not accurate

Since the image is a fixed-point image acquisition, in order to collect the surface image of the filling barrel at one time, not only the position of the point is relatively high, but also the surrounding of the filling barrel is an open structure, and the surrounding of the filling barrel is also used as the surface of the filling barrel. Part of the image, the foreign matter around the filling barrel, especially the dark foreign matter, has become the scope of image acquisition. Due to the great influence of environmental factors around the filling barrel, the phenomenon of misjudgment of the position of the barrel mouth will occur, which will affect the reliability of filling. When dealing with highly toxic and highly corrosive liquids, the operating safety is greatly reduced
