The work aims to design a parallel robot based egg picking and placing packaging production line to improve the efficiency and cost of egg packaging processing. According to the actual demand of egg packaging, an egg packaging and processing production line was designed, which consisted of conveying part, parallel robot, sensor, egg carb conveying part, etc. The ethical analysis and calculation were made on the picking and placing path and scheme of the robot, and the optimal picking and placing scheme of the robot was obtained through experimental comparison. Three tests were carried out for each of the 64 picking and placing schemes, and the picking and placing of 30 eggs in a whole group was completed each time. The success rate of the picking and placing robot was 99.3%. Under the premise of ensuring the success rate and accuracy, the fastest speed of the robot for one round of picking and placing was 2.4 seconds. The design of the egg picking and placing packaging production line is in line with the expected design requirements, which provides technical support for the application of the parallel robot in egg packaging.
