Loading mechanical arm for automatic loading equipment

Abstract

The invention discloses a loading mechanical arm for automatic loading equipment. The loading mechanical arm comprises a base which can be connected to a loading machine, an upper arm mechanism which rotates relative to the base, a lower arm mechanism linked with the upper arm mechanism, a load mechanism connected with the lower arm mechanism and capable of moving in the vertical direction, and a driving mechanism for driving the upper arm mechanism to rotate. The loading mechanical arm is provided with the upper arm mechanism and the lower arm mechanism which can rotate relatively, so that the lifting space above the mechanical arm is saved; and the vertical lifting motion of the load mechanism can be realized by arranging one driving mechanism, so that the structural design is simplified, and the overall manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of automatic loading, in particular to a loading mechanical arm used for automatic loading equipment. Background technique [0002] In the fields of industrial assembly, logistics, and automatic loading, robotic arms are more and more widely used, especially in the current loading field. It has become a trend to achieve low-level bag dropping through robotic arms. Low-level bag dropping can not only significantly reduce bagged materials. The rate of bag breakage is high, and for materials that are prone to dust, it can significantly reduce the generation of dust. For the palletizer head, the realization of low-level bag drop requires the help of a mechanical arm that can penetrate into the carriage. Its action flow is as follows: First, the gripper on the mechanical arm picks up the bagged materials conveyed by the conveying mechanism inside the machine head, then the mechanical arm extends downward in the height dir...

Problems solved by technology

However, the single-axis manipulator mainly moves vertically, and the manipulator cannot be bent or folded. Therefore, when the manipulator moves to the upper limit, there needs to be a space above for the manipulator to move, and the height of this space needs to be greater than Or equal to the lifting stroke of the mechanical arm, the overall design structure is not compact enough, and the space utilization rate is low

[0004] In addition, the SCARA robot has three rotary joints, whose axes are parallel to each other, and is positioned and oriented in the plane. When the arm rises to the upper limit, the upper arm and the lower arm will be folded inside the nose, which does not occupy the upper space and has a compact space structure. , but compared with the single-axis mechanical arm, the SCARA robot has a complex structure. There are three motors on the three joints, and the three axes need to be controlled in conjunction to realize the vertical lifting action of the load. Therefore, for manufacturers, the production and high manufacturing costs, and the complexity of its structure is not conducive to the installation and maintenance of manufacturers
