Applications

 

Tighten and assembly the indicator light

The RGI-35-14 rotary gripper was applied to complete the automatic tightening and assembly process of indicator lights on the production line.


Lock the end of the bulb

The RGI-35-30 rotary gripper was applied to complete the bulk locking assembly of the bulb ends.

Task difficulty: rotation and grasping synchronization, precise force control, position control, small space


Multi-channel nucleic acid virus divider

The dimension of RGI series is only 50×50 mm with a slender structure that can support the side-by-side installation and operation of multiple grippers in a limited space. Compared with a single-channel device, the multi-channel nucleic acid virus beaker can support simultaneous processing of 2 or 4 sets of samples, which is more efficient.


Automated cup processing system

The automatic sub-cup processing system, through ABB’s Scara robotic arm and DH-Robotics electric gripper, can automatically complete the operation of sample tube opening, scanning, information entry, pipetting, turning plate, and closing lid. The whole process is in a closed negative pressure state to ensure that the sample is clean and free from contamination.


Multi-channel test tube opening and closing lid

The medical industry often involves the processing of large quantities of samples, and more efficient solutions are needed to meet this challenge. The RGI series has a length and width of only 50×50 mm and a slender structure. It can support the side-by-side installation and operation of multiple grippers in a narrow space. Therefore, it can complete the opening and closing tasks of multiple test tubes at one time and improve efficiency.


Test tube opening and closing lid

Opening and closing the lid of the test tube is the most common standard task in the medical industry, and the needs of sample testing, preparation, and cupping are all involved. The DH-Robotics RGI series servo rotating electric gripper can complete grasping and infinite rotation tasks on the same gripper, meeting the requirements of the medical automation field for the accuracy, efficiency, cleanliness and aesthetics of the opening and closing tasks.

All products of DH-Robotics electric grippers have obtained CE, FCC, and RoHS certifications.
