This invention discloses a visual buffer pick-and-place device and method for microneedles. The device includes a feeding assembly, a pick-and-place assembly, and a feeding assembly. The feeding assembly includes a vibrating plate and a visual screening unit. The vibrating plate disperses the vibration of the microneedles, and the visual screening unit acquires images of the microneedles, filters and identifies individual microneedles, and provides feedback on the position and orientation information of the individual microneedles. The feeding assembly includes a feeding seat and a pressure-adjusting buffer structure. The feeding seat has a feeding groove, and the pressure-adjusting buffer structure provides a buffer positive or negative pressure to the feeding groove. The pick-and-place assembly includes a suction head, a pressure-adjusting pick-and-place structure, and a driving structure. The suction head has several microholes communicating with the pressure-adjusting pick-and-place structure. By generating negative pressure at the microholes, the individual microneedles are picked up. The driving structure drives the suction head to reciprocate between the feeding assembly and the feeding assembly, and delivers the individual microneedles to the feeding groove according to the position and orientation information to complete the feeding operation.
