The invention discloses an automatic assembly method for couplings based on machine vision, which includes the following steps: transmitting the left half coupling so that the left half coupling with the notch facing up is normally transmitted to the bottom of the elastic body assembly platform, and the elastic body alignment assembly to form a coupling kit; transfer the right half couplings in different orientations so that the notch of the right half coupling on the second assembly platform faces to the left; transfer the received elastic body into the assembly hole, The elastic body is pressed into the left half coupling with the notch facing up by the assembly pressing rod; the first assembly platform receives the coupling kit, and the second assembly platform receives the right half coupling; using the camera group, identify The positions and orientations of the left half-coupling, the elastic body and the right half-coupling transmit the recognition results to the left platform, right platform and left and right assembly platforms.
Description
technical field [0001] The invention relates to the technical field of coupling assembly, in particular to an automatic assembly method for couplings based on machine vision. Background technique [0002] The plum blossom coupling is a kind of flexible coupling, which is used in various mechanical equipment and mechanical devices to realize the connection between shafts and transmit torque and power. my country's total demand for couplings in 2017 was 54.2 billion yuan, and plum blossom couplings accounted for a large share. With the rapid development of the national economy, the demand for plum blossom couplings is also increasing year by year. [0003] However, the plum blossom couplings of the prior art are all manually installed, such as figure 1 As shown, after manually aligning the left half-coupling 2-1, the plum-shaped elastic body 2-2, and the right half-coupling 2-3, start the pneumatic device (usually use a foot to step on the pneumatic switch), and the pneumati...
