Description

Technical Field

[0001] The utility model relates to the technical field of spraying robots, in particular to an automatic batching device for spraying robots. Background Art

[0002] Spraying robots, also known as paint spraying robots, are industrial robots that can automatically spray paint or other coatings. They were invented by a Norwegian company in 1969. Spraying robots are mainly composed of a robot body, a computer and a corresponding control system. Hydraulically driven spraying robots also include hydraulic oil sources, such as oil pumps, oil tanks and motors. Most of them adopt a 5- or 6-degree-of-freedom articulated structure. The arm has a large movement space and can perform complex trajectory movements. Its wrist generally has 2 to 3 degrees of freedom and can move flexibly. The wrist of the more advanced spraying robot adopts a flexible wrist, which can bend in all directions and rotate. Its movement is similar to that of a human wrist. It can easily reach into the workpiece through a smaller hole and spray its inner surface. Spraying robots are generally hydraulically driven and have the characteristics of fast movement speed and good explosion-proof performance. Teaching can be achieved through hand-to-hand teaching or point indication. Spraying robots are widely used in process production departments such as automobiles, instruments, electrical appliances, and enamel.

[0003] However, the existing spraying robots are mostly manually batching and stirring the spray paint during spraying work. The manual batching work is large in workload and low in efficiency, and some ingredients are harmful to the human body. Some automatic batching devices use longer catheters to introduce the measured quantitative ingredients into the mixing equipment for mixing and stirring. However, since some ingredients are sticky, they are adsorbed and trapped in the catheter and cannot fully enter the mixing equipment, which not only causes inaccurate batching problems, but also wastes ingredients. Therefore, the utility model proposes an automatic batching device for a spraying robot to solve the deficiencies in the prior art. Utility Model Content
