Embodiment Construction
[0017] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:
[0018] Such as Figure 1-3 As shown, the gripper mechanism used for blood cell analyzers in the present invention includes a mounting plate 1, a motor 2 is installed on the back of the mounting plate 1, a gear 3 is installed on the rotating shaft of the motor 2, and the gear 3 is in phase with the gripper 4. meshing, a catch 5 is installed in the gripper 4, the gripper 4 is installed on the linear slide rail 7 through the slide rail seat 6, and the linear slide rail 7 is fixedly installed on the mounting plate 1, that is to say, the gripper 4 is mounted on the motor Under the transmission of 2, it can move back and forth on the linear slide rail 7. In this way, the length of the linear slide rail 7 can be set according to the actual production requirements to meet the requirements of the red blood cell analyzer for the stroke of the gripper 4, thereby e...

The invention discloses a gripper mechanism for a blood cell analyzer, comprising a mounting plate, a motor is mounted on the back of the mounting plate, a gear is mounted on the rotating shaft of the motor, the gear is meshed with the gripper, and a stopper is mounted on the gripper The gripper is installed on the linear slide rail through the slide rail seat, and the linear slide rail is fixedly installed on the mounting plate; a surrounding frame is installed on both sides of the mounting plate, and the surrounding frame includes the photoelectric sensor installation part, which is in the photoelectric sensor part. A photoelectric sensor assembly is installed, and the electric sensor assembly is located above the baffle and arranged opposite to the baffle; the photoelectric sensor assembly is signal-connected to the controller, and the controller is signal-connected to the motor to control the rotation of the motor. The invention is not only compact in structure, but also can make the stroke of the gripper meet the requirements of the blood erythrocyte analyzer by setting linear slide rails of different lengths; meanwhile, the movement of the gripper can be precisely controlled by arranging a photoelectric sensor assembly.
Description
technical field [0001] The invention relates to medical equipment, in particular to a handle mechanism for blood cell analyzers. Background technique [0002] The red blood cell analyzer is one of the most widely used instruments in hospital clinical testing. The red blood cell analyzer is mainly used to absorb, dilute, transfer, mix the sample, and move the sample into the detection area of various parameters. Among them, the red blood cell The transmission action of the analyzer is mainly completed by its transmission parts, but the transmission parts of the current red blood cell analyzer mainly have the absence of inaccurate movement and too few strokes, which affect the accuracy of the detection results of the red blood cell analyzer. [0003] Patent document CN1334453A discloses "a device for processing blood product samples". This technical solution also discloses a transfer device, which includes: a carriage that can be fixed on the box through a retractable handle...
