Description

Technical Field

[0001] The present invention belongs to the technical field of cargo sorting, and in particular relates to an intelligent mechanical arm for logistics handling. Background Art

[0002] Against the backdrop of deepening global economic integration, the e-commerce sector is booming and developing rapidly. As an important support for e-commerce, the logistics industry has also ushered in an unprecedented development opportunity and achieved explosive growth. Relevant statistics show that in the past few years, the scale of the global logistics market has continued to expand steadily, and the business volume has shown a geometric growth trend.

[0003] In the face of such a huge business volume, logistics sorting, as a crucial link in the logistics process, has become increasingly important. Its efficiency and accuracy, like the lifeline of the logistics system, directly determine the operational efficiency of the entire logistics system. In order to improve the efficiency of logistics sorting, people developed some relatively simple automated sorting equipment in the early days, among which the most typical one is the sorting robot arm.

[0004] This type of sorting robot mainly uses mechanical structures to complete the classification of goods. It has to be admitted that it does improve the sorting speed to a certain extent and plays a certain role in handling some specific types of goods. However, its limitations are also very obvious. It has poor flexibility and can only effectively handle goods with regular shapes and uniform sizes. But in modern logistics, goods have different shapes and sizes. Faced with such complex and diverse types of goods, early sorting robots are obviously difficult to meet actual needs.

[0005] In addition, on the logistics conveyor belt, the placement of goods is often chaotic and irregular. Most sorting devices lack the ability to adjust the clamping according to the placement of the goods. This makes it difficult to ensure stability during the clamping process, and the goods often fall, which may damage the items inside the goods and bring unnecessary losses to logistics companies.

[0006] In view of the above problems, based on practical needs, there is an urgent need for an intelligent robotic arm for logistics handling to solve the above problems existing in the prior art. Summary of the invention
