Problems solved by technology

[0003] There are also some people in China who have conducted research on robot sorting systems based on machine vision and have achieved certain results. Most of the currently developed sorting systems are based on the existing industrial robot systems of well-known manufacturers. Through serial ports, Ethernet Etc information mode, data communication with the machine vision system to realize the integration of the sorting system, and such a system architecture makes the machine vision system and the robot system relatively independent, poor flexibility, low openness, high dependence, and inconvenient operation. Poor portability, at the same time, it is difficult to communicate and connect the two systems, and the development cycle is long

Embodiment 1

[0104] In the area 6 of the items to be sorted, randomly scatter some areas with an area of ​​about 16mm 2 , round vitamin B tablets, using this robot sorting system based on machine vision to complete the sorting of scattered tablets, the specific steps are as follows:

[0105] 1) Select and input the characteristics of scattered vitamin B pills, and determine that the target item to be sucked is vitamin B pills.

[0106] Create a new target item vitamin B tablet in the interactive interface, and input it according to the order of the features, select the shape as a circle, and fill in the area as 16mm 2 , Fill in the allowable error ±5%, confirm and store.

[0107] 2) Use an industrial CCD digital camera to collect scattered vitamin B tablets, and after obtaining the overall image, transmit the image data information to the industrial computer through Ethernet.

[0108] 3) Use an image processing program to Figure 4 The image in (a) is processed by threshold segmentation...

Abstract

The invention discloses a system and a method for machine vision-based robot sorting. The system comprises a CCD digital camera, a camera lens, a light source, a six-axle joint robot main body, an electrical control cabinet and a vacuum sucker. The CCD digital camera is connected to an industrial computer by a switch. The six-axle joint robot main body is connected to the electrical control cabinet. The electrical control cabinet accesses the switch. The vacuum sucker is rigidly fixed to the tail end of the six-axle joint robot main body. The camera unit is used for making a photo of an object to be sorted, collecting data and transmitting the data to the industrial computer by the switch. The industrial computer is used for treating the acquired photo of the object to be sorted, carrying out accurate positioning and then transmitting a control signal to the electrical control cabinet by the switch. The electrical control cabinet is used for controlling the six-axle joint robot main body to carry out corresponding sorting processes according to the received control signal. The system and the method improve work efficiency, reduce operation workers and reduce a production cost in sorting.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a robot sorting system and method based on machine vision. Background technique [0002] Sorting operation is an important link in most assembly lines. Compared with manual sorting operations, robot sorting based on machine vision is not only efficient and accurate, but also has irreplaceable advantages in terms of quality assurance and hygiene protection; compared with traditional mechanical sorting operations, machine-based Visual robot sorting has the advantages of a wide range of adaptation, and the ability to change the operating object and sorting process at any time. Robot sorting technology is an organic combination of robot technology and machine vision technology. In Japan and some developed countries in Europe and the United States, the application of robot sorting in the production fields of machinery, food, medicine, and cosmetics has become quite popular...
