AI Technical Summary
In existing fully automated chemiluminescence devices, the reaction cup is only constrained by horizontal limits, lacking vertical limits. This makes the reaction cup prone to falling during transportation, and the multi-claw self-centering effect is poor, resulting in severe wear of the cam.
Design a cup gripper device that combines a movable end gripper and a fixed end gripper, with a total of three grippers. Vertical positioning is achieved by the groove structure of the movable end gripper matching the flange skirt, and the gripping drive mechanism drives the gripper to pick up the reaction cup. The contact point between the gripper and the reaction cup achieves three-point self-centering, reducing wear.
It effectively ensures the accurate positioning of the reaction cup, prevents it from falling, improves the self-centering effect, reduces wear, and extends the service life of the device.
