Automatic recognition mechanical gripper special for tray

Abstract

The invention discloses an automatic recognition mechanical gripper special for a tray. The gripper comprises a mounting base. A first gripper unit and a second gripper unit are arranged on the left and right sides of the mounting base correspondingly and driven by a power unit to open and close. The power unit comprises a power source and a linkage mechanism which are used for driving the first gripper unit and the second gripper unit to open and close synchronously. A recognition module is arranged on the first gripper unit or the second gripper unit. A single floating correction assembly is arranged on the first gripper unit or the second gripper unit. According to the automatic recognition mechanical gripper special for the tray, a penetration lead screw motor used as the power source and a synchronous belt transmission pair used as the linkage mechanism jointly achieve fast opening and closing of the first gripper unit and the second gripper unit, the linear moving trajectories of the two gripper units are limited through a linear guide component, the stability is good, and the motor selection range is wide.

Description

technical field [0001] The invention relates to the field of in vitro detection, in particular to a special mechanical gripper for pallet transfer that can be automatically identified. Background technique [0002] In the field of in vitro testing, sample pretreatment is a key factor affecting the accuracy and reliability of sample test results. In order to improve detection efficiency, grippers are often used to grab and transfer trays during sample pretreatment. Therefore, the mechanical gripper is the key component to ensure the stable transfer of the pallet. [0003] CN204076252U discloses a self-adaptive microboard gripper, the motor drives the first straight rack and the second straight rack to move relative to each other in the horizontal plane through a pinion shaft, so as to realize the grabbing operation of the microboard. Although the microplate can realize the automatic return of the skewed microplate after grabbing the skewed microplate, it has the following p...

AI Technical Summary

Problems solved by technology

Although the microplate can realize the automatic return of the skewed microplate after grabbing the skewed microplate, it has the following problems in use: the two grippers are driven to open and close by the rack and pinion, and the rack and pinion are relatively small, which is difficult for maintenance. The space is small, the maintenance is difficult, and the standby time is long; at the same time, due to the small rack and pinion structure, the motor selection range is small; the microplate cannot be automatically identified during the process of grabbing the microplate, and the operator needs to visually observe whether the microplate is in place
