Many of the first, first research Meizhi brave to create a “no man’s land”

The automation of air conditioning compressor production line has always been a hard bone in the industry, which is mainly because of three aspects of difficulties: first, the production line is changed more, and the flexible production needs should be considered while the automatic transformation; Second, the precision requirement is high, and the micron error needs to be realized by the full cooperation of the robot and the algorithm; Third, the production line is fast, and the stability and low failure rate of automation equipment are required.

DSTC190 Taking the core-adjusting workshop as an example, the work of the core-adjusting wire is to select the 6 major components in the compressor pump body with 3 micron accuracy, and then accurately assemble to 1 micron concentricity. It should be known that the precision of the compressor pump body directly affects the performance of air conditioning noise, wear resistance and energy efficiency, so it is necessary to ensure high quality products with high precision manufacturing, and the difficulty of automation is also increased.

For example, in the flexible assembly automation project of the crankshaft piston with the core wire, the matching gap between the parts is only 13 microns, and the industry has been using manual assembly, and there is no precedent in automation. Wu Gong said: “As the core part of the compressor, workers in this part of the handling and grasp when the workpiece collision, even very slight will cause injury, the subsequent operation may appear noise and even stuck.” In order to improve product quality and reliability, Meizhi Ronggui factory research and introduction of flexible robots, through real-time torque feedback to achieve precision assembly, while eliminating the risk of workpiece injury, Meizhi this “first” results after landing also provides a wide range of reference for the industry.

DSTC190 In addition to making the production assembly more accurate, the automation replacement also optimizes the production process through the interconnection between different automation equipment and systems. For example, the riveting link of the main bearing needs to check the riveting height and appearance after the riveting is completed, and its quality is directly related to the operating noise of the compressor, but in the past, it has relied on workers to visually detect the appearance, and the accuracy is not enough. In order to improve the inspection effect, achieve standard refinement and quantification, Meidji has developed a riveting automatic machine, which can fully detect all parts before and after riveting, and retain the test data. In this way, the entire riveting process has a total of 8 quality anti-stay synchronous detection, such as laser measurement and AI appearance, which greatly improves the detection efficiency and accuracy compared with the traditional one-time manual visual inspection.

Today, the core intelligent black light workshop has achieved up to 94.4% automation coverage, 10,000 robots have reached 1,000 units, and there has been a significant improvement in production capacity and quality, single-shift output has increased by 20% compared with the original, and the three-level QEP anti-stay on the representative of product quality has achieved full coverage, and product quality is more stable and reliable. With industry-leading precision assembly automation and intelligent level, Meizhi core intelligent black light workshop was also selected as “Foshan Intelligent Demonstration Workshop” in 2022.
