Description

Technical Field

[0001] The utility model relates to the technical field of robot lifting, in particular to a robot lifting platform. Background Art

[0002] The previous robot lifting mechanism uses a motor to drive a lead screw to rotate. The lead screw drives a mechanical arm connected to the nut to lift through the nut. As the above conventional lifting structure, the lifting distance of the lead screw drive is related to the pitch. However, the pitch of the lead screw is usually smaller than the diameter. Therefore, the rotation speed of the motor needs to be relatively high during lifting, and the lead screw is subjected to large force, high noise, easy wear during lifting, and high requirements for later maintenance.

[0003] The existing publication number CN207240188U discloses a robot lifting mechanism, including a machine base. A motor and a reducer are installed at the top end of the machine base. A main shaft is arranged in the inner cavity of the machine base. The main shaft is installed on the machine base through bearings. Active sprockets are installed at both ends of the main shaft, and a driven bevel gear is installed in the middle of the main shaft. A driving bevel gear meshing with the driven bevel gear is installed on the output shaft of the reducer. Bearing seats are arranged on both sides at the bottom end of the machine base. A slave shaft is installed in the bearing seat. A driven sprocket connected to the corresponding active sprocket through a chain is installed on the slave shaft. Linear guide rails and linear sliders are installed on both sides of the inner cavity. A lifting plate is installed on the linear slider. A block capable of fixing the chain and the lifting plate is arranged on the lifting plate. The lifting of the mechanical arm is realized through the combination of gear transmission and sprocket transmission. The above structure not only has a large transmission torque, but also when lifting the same height, the rotation speeds of the gear and the sprocket are much lower than that of the lead screw. Therefore, it is quieter, wear-resistant, easy to maintain, has low requirements for the use environment, and has a long service life.

[0004] However, when the above robot lifting mechanism is in use, it cannot meet the accuracy requirements of the robot, and the lifting platform does not have high-precision positioning ability. Summary of the Utility Model
