The invention provides in-vitro diagnosis equipment and a stirring
paddle anti-collision device of the in-vitro diagnosis equipment. The equipment comprises the stirring
paddle anti-collision device, a driving device and a
control system, wherein the driving device and the
control system are electrically connected with the stirring
paddle anti-collision device. The stirring paddle anti-collision device comprises a motor, a stirring paddle, a motor mounting
assembly and an anti-collision sensing
assembly, wherein the motor is arranged on the motor mounting
assembly in a sliding mode, the anti-collision sensing assembly is assembled on the motor mounting assembly, the motor is provided with a first end face abutting against the mounting assembly and a second end face abutting against the anti-collision sensing assembly, and a clamping part for connecting a
motor shaft and the stirring paddle is arranged between the
motor shaft and the stirring paddle. When the stirring paddle anti-collision device is prevented from descending, rotating and swinging along with the driving device, the stirring paddle pushes the motor to rebound along the mounting assembly and trigger the anti-collision sensing assembly to output a
signal to the
control system, the equipment stops moving or reversely moves back to a safe position according to program setting, the stirring paddle is prevented from being damaged, and then the shutdown loss and the instrument maintenance cost are reduced.
