Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading, in particular to a material detection system for a dump truck compartment. Background Art

[0002] As labor costs continue to rise, more and more industrial fields have begun to use automated equipment such as robots to replace manual operations. For example, product sorting on the production line, identifying product types based on collected images, using robotic arms to grab products, and sorting and loading products according to corresponding sorting rules based on product types.

[0003] However, in some industrial production environments with high safety requirements, automated production cannot be achieved only by controlling the manipulator. For example, when the material in the carriage reaches a certain height, the unloading valve is automatically closed. At present, the material loading process still requires staff to participate in the entire material loading process and coordinate all matters in the material loading process. For example, because the carriage is relatively long, it is necessary to move the vehicle multiple times to coordinate the material loading and unloading operations to ensure that the materials in the truck carriage are loaded evenly and there is no material overflow. However, this method is based on human line of sight. It can be seen that the existing material loading technology has a low degree of automation and a lot of uncertainty. Utility Model Content
