Novel connecting-rod type mechanical arm

Abstract

The invention discloses a novel connecting-rod type mechanical arm. The mechanical arm comprises a rack, a horizontal moving assembly arranged on the rack, a lifting assembly and a material taking assembly. The horizontal moving assembly comprises a first horizontal motor, a first horizontal carrying plate, a second horizontal motor and a second horizontal carrying plate, wherein the second horizontal carrying plate is connected with the first horizontal carrying plate in a sliding mode, the first horizontal motor drives the first horizontal carrying plate to move horizontally, and the second horizontal motor drives the second horizontal carrying plate to move horizontally. The lifting assembly is arranged on the second horizontal carrying plate and comprises a lifting motor and a lifting carrying plate connected with the lifting motor in a transmission mode, and the lifting motor drives the lifting carrying plate to ascend and descend. The material taking assembly comprises a mechanical arm body arranged on the lifting carrying plate and at least one suction foot arranged on the mechanical arm body, wherein each suction foot is provided with a vacuum sucker or an electromagnet assembly. The novel connecting-rod type mechanical arm is simple in structure, the cost is low and the requirement for arrangement of a die and a punch press is low and capable of effectively improving the integral production efficiency of products and lowering production cost.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a novel link-type manipulator. Background technique [0002] The traditional connecting rod manipulators currently on the market for stamping, and because all the mechanical arms of the traditional connecting rod manipulators move back and forth uniformly, have higher requirements for the arrangement of molds and punching machines. For example, the traditional link-type manipulator requires that the centers of all punches must be on the same straight line, the center distances of all punches must be consistent, the heights of all lower dies must be the same, and the center distances of all molds must be consistent. The above requirements virtually increase the cost of production. In many cases, this problem is particularly significant when customers need to produce small batches of products with multiple varieties. The traditional link-type manipulator is very complicated...

The above requirements virtually increase the cost of production

In many cases, this problem is particularly significant when customers need to produce small batches of products with multiple varieties. The traditional link-type manipulator is very complicated to debug, and it takes a lot of energy to re-layout the mold and punching machine, consuming a lot of time. manpower and material resources

Although the problems existing in the traditional link-type manipulator can be solved by using a four-axis manipulator or a five-axis manipulator, due to the increase in the number of joint axes of the four-axis manipulator or five-axis manipulator, the production efficiency is reduced and the production cost is increased.
