The invention discloses a clamping device and method of a circular thin-sheet-shaped part with the thickness of 50-200 microns. The device comprises a base 1, a manual adjusting platform 2 with three degrees of freedom, a micro-force sensor 3, a ventilating cantilever 4 and a clamping part, wherein the clamping part comprises an air hole plug 5, a ventilating pipe fitting 6 and a clamping head 7. The method comprises the following steps of: firstly, aligning the clamping head to the part to be clamped in the vertical direction according to an image collected by a microscopic vision lens in the vertical direction; secondly, controlling the clamping head to be close to the part to be clamped according to the image collected by the microscopic vision lens in the horizontal direction; when the distance between the clamping end and the part to be clamped is 200 microns, opening a vacuum adsorption device to generate an adsorption force to realize a clamping operation; and finally, driving the part to be clamped to move to a target assembling position by the clamping device, and adjusting the movement of the clamping device according to an assembling force which is generated by contacting the part to be clamped with the other parts and is sensed by the micro-force sensor, thus realizing a target of lossless clamping of the part.
Description
technical field [0001] The invention relates to the technical field of precision assembly, in particular to a clamping device and method for circular sheet parts. Background technique [0002] In the field of precision assembly, there is a class of circular thin parts (thickness 50-200 microns), which are easily damaged during the clamping process using traditional clamping methods or devices, which cannot meet the requirements of precision assembly. Therefore, there is an urgent need for a new type of clamping device and method based on microscopic vision and force sense control to achieve non-destructive clamping of such parts. Contents of the invention [0003] The object of the present invention is to provide a clamping device and method for circular thin sheet parts in precision assembly, to realize non-destructive clamping of parts based on microscopic vision and force sense information, to overcome the shortcomings of traditional clamping methods and improve circula...
