Description

Technical Field

[0001] This utility model relates to the field of visual positioning and grasping technology, specifically a machine vision positioning device. Background Technology

[0002] In modern industrial production, logistics warehousing, and numerous automated operation scenarios, gripping devices are widely used. Traditional gripping devices mostly adopt a single-grip method, meaning they can only grip one object at a time, and after gripping, the object needs to be placed on a conveyor belt before returning to its original position to prepare for the next gripping. This single-grip mode has a significant efficiency bottleneck.

[0003] First, from a time cost perspective, after each object is grabbed, time is required to place it on the conveyor belt, followed by a return motion. This series of reciprocating movements makes the entire grabbing process time-consuming. Especially when dealing with scenarios where a large number of objects need to be grabbed, this inefficient grabbing method will greatly limit the overall progress of production or operations, making it difficult to improve work efficiency.

[0004] Secondly, while a single gripping device is relatively simple in structure, its functional limitations are also quite obvious. Since it can only grip one object at a time, its gripping capacity is not fully utilized, failing to meet the demands of high-efficiency, high-volume gripping. On some production lines, to meet production efficiency requirements, multiple single gripping devices are often needed, which not only increases equipment investment costs but also complicates equipment layout and management.

[0005] With the continuous development of industrial automation technology, higher demands are being placed on the efficiency and performance of gripping devices. To overcome the limitations of traditional single gripping devices, improve gripping efficiency, and reduce the time wasted in reciprocating motion, a new type of gripping device capable of grasping multiple objects at once is urgently needed. Simultaneously, the application of visual positioning technology is particularly important to ensure the accuracy and reliability of gripping. Through a visual positioning system, multiple objects can be accurately identified and located, thereby achieving efficient and accurate multi-object gripping.

[0006] Based on the above background, this application proposes a visual positioning grasping device, which aims to solve the problems of low efficiency and wasted time of existing single grasping devices. By improving the design of the device, it can grasp multiple objects at a time, and by combining visual positioning technology, the efficiency and accuracy of grasping are improved, so as to meet the needs of modern industrial production and other fields for efficient and automated grasping.

[0007] Therefore, a machine vision positioning device is needed to improve the above problems. Utility Model Content
