Technical Field

[0001] The utility model relates to the field of robots, in particular to a robot end-lifting mechanical arm. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. It can perform tasks such as operation or movement through programming and automatic control. A robot is an automated machine. The difference is that this machine has some intelligent capabilities similar to humans or creatures, such as perception, planning, movement and coordination. It is an automated machine with high flexibility. Usually robots are used in heavy physical, high-precision and high-risk operations.

[0003] However, the mechanical arms of lifting robots usually adopt a lever-type lifting method, and direct driving results in limited lifting weight. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a robot lifting mechanical arm, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a robot end-lifting mechanical arm comprises a robot base, a rotating seat is installed on one side end above the robot base, a mechanical arm is arranged inside the rotating seat, and the mechanical arm comprises: a first swing arm and a second swing arm, a winding roller is installed on one end of one side of the robot base close to the rotating seat, a winding motor is installed on the outer side of the winding roller, a winding rope is wound on the outer side of the winding roller, a lifting ring is installed on the upper end of the winding rope on the lower surface of the second swing arm, a fixed pulley is installed on the inner side of the rotating seat on the outer side of the winding rope, an arm lifting motor is installed on the outer side of the lower end of the rotating seat, a transmission groove is opened on the inner side wall of the rotating seat, and a transmission gear group is arranged inside the transmission groove.

[0006] As a further solution of the utility model: a guide groove is provided on the upper surface of the robot base, and a supporting box is installed inside the guide groove.

[0007] As a further solution of the utility model: a movable hinge is installed between the first swing arm and the second swing arm, and a placement pad is installed at the end of the first swing arm away from the winding motor.

[0008] As a further solution of the utility model: a movable hinge is installed between the first swing arm and the second swing arm, and a placement pad is installed at the end of the first swing arm away from the winding motor.

[0009] As a further solution of the utility model: a movable shaft is installed between the transmission gear set, the second swing arm and the rotating seat.

[0010] As a further solution of the utility model: the supporting box is movably connected to the guide groove.

[0011] As a further solution of the utility model: the lifting ring is fixedly connected to the second swing arm.

[0012] As a further solution of the utility model: the placement pad is fixedly connected to the first swing arm, and the first swing arm and the second swing arm are movably connected via the movable hinge.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The arm lifting motor as a whole drives the transmission gear group to rotate, thereby driving the second swing arm as a whole to swing inside the rotating seat. The winding motor as a whole drives the winding roller to rotate. Winding the winding rope as a whole will pull the lifting ring under the second swing arm downward, thereby advancing the lifting force of the entire robotic arm.

[0015] By controlling the entire supporting box to slide inside the guide groove, heavy objects can be filled inside the supporting box, thereby changing the center of gravity position of the entire robot base and ensuring the stability of the lifting. BRIEF DESCRIPTION OF THE DRAWINGS
