Schematic PCB

Based on STM32H747, Arduino® Nicla vision development board schematic

Arduino® Nicla Vision is a ready-to-use standalone camera for analyzing and processing images at the edge. It's suitable for asset tracking, object recognition and predictive maintenance thanks to its 2MP color camera, smart 6-axis motion sensor, integrated microphone and distance sensor. Quickly implement sensor nodes that send collected data to the Arduino® Cloud (or third-party vendor service) via integrated WiFi/BLE connectivity.

Tool changing manipulator design

The manipulator is the main tool for exchanging tools in the automatic tool changer. It is responsible for sending the tools from the tool magazine to the spindle, and then returning the used tools from the spindle to the tool magazine. The design idea is to use the movement of the manipulator to change the tool of the machining center. The rotation of the manipulator is realized by a rotary pneumatic cylinder or a rotary pneumatic cylinder, and its power is realized by the drive system. The automatic tool changer of a machining center is usually composed of a tool magazine and a manipulator. It is a symbol of the machining center and a key link to the success or failure of the machining center. Therefore, all machining center manufacturers are working hard to develop automatic tool changers with fast action and high reliability in order to achieve good results in the fierce competition. Automatic tool changers are the core content of machining centers, and each manufacturer is keeping it secret. Very little relevant information is disclosed, especially the robot part. The knife extraction and knife insertion actions of the manipulator are mostly completed by the pneumatic cylinder or the action of the pneumatic cylinder. The entire manipulator is composed of a mechanical arm telescopic mechanism, a mechanical claw opening and closing mechanism, a rotary mechanism and a linear motion mechanism for loading and unloading tools.
