Abstract

The invention provides a linear rotary motor for SMD pick-and-place, and relates to the technical field of motors. The linear rotary motor includes: a casing, a voice coil motor stator, a guide rail and a voice coil motor mover; the voice coil motor mover includes: a rotary motor stator, a rotary motor rotor, a permanent magnet and a slider. In the present invention, the rotary motor is integrated in the mover of the voice coil motor, and the voice coil motor and the rotary motor share a set of permanent magnets. The permanent magnet is not only the permanent magnet of the mover of the voice coil motor, but also the permanent magnet of the stator of the rotary motor. The rotary motor is light in weight and small in size, which reduces the space installation size, simplifies the internal structure, and reduces the load of the linear motor. Both linear and rotational degrees of freedom are driven by electromagnetic transmission, which effectively improves the positioning accuracy of the linear rotary motor. .

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear rotary motor for SMD pick-and-place. Background technique [0002] At present, my country has become the largest foundry in the world, and the advantage of cheap labor is gradually weakening. The model of human assembly line is not sustainable. There are more and more high-speed automation equipment involved. Among many high-speed automation equipment, voice coil motors are widely used in precision positioning systems and many different forms of automated assembly systems due to their advantages of high response, high speed, high acceleration, simple structure, small size, and convenient control. [0003] In the actual application scenarios of voice coil motors, it is often required to have two degrees of freedom, linear and rotational, so as to adapt to precision positioning systems and many different forms of automated assembly systems. Existing linear rotary motors of...
