Sequoia Automation first purchased two Fanuc CNC Mate 200i production robots from Yamazen, and also included two NV4G CNC double-tray vertical CNC machining centers from NTC Americas, equipped with multi-functional fixtures for processing. The company's high volume orders.
The Mate 200i robot designed by Fanuc has a compact structure and can be used as a low-cost machine tool solution. The unit was developed as a complete package and can be interfaced directly to the machine. The complete self-contained system unit consists of a 6-axis robot with an arm length of 19 in. The robot can be mounted on lathes, milling machines, machining centers and other machine tools to service workpieces with a loading height of 36 to 44 in. The robot is lightweight (only 1050Ib) and can be used for lifting equipment to be installed on any machine in the factory that matches or allows it to be accessed.
The robot can move a few feet away
Sequoia Automation only needs the robot to move a few feet to the side to get closer to the machine. The robot's arm is mounted on a platform that slides left and right, allowing it to move back and forth between the loading and unloading areas of the machine tool. The right side of the shield can be moved with the platform and telescoped to the left side of the shield. When the platform is fully extended to the right, the robot is directly in front of the workpiece loading and unloading area, and the protective cover covers an area of ​​3 × 7 ft.; when it is stretched to the left, its area is reduced to 3 × 4 ft.
To move the robot laterally away from the machine, the two pins must be removed before the robot can move to the left. Repositioning of the robot directly in front of the machine workpiece loading and unloading area requires the operator to push the robot back to its original position, reinstall the pin on the panel of the shield, and screw the mounting block to the platform. On the stand until the stand touches the ground, the robot is ready to start working.
Currently, Sequoia Automation is using its newly installed robotic device to load and unload workpieces on a two-tray vertical machining center, which is the connection to the automotive air conditioning system. Vertical machining centers are arranged in a side-by-side arrangement, and each machine is used for both sides of the part.
Processing order
When the connecting piece is processed, firstly, the robot moves from the workpiece picking station of the workpiece library to an extruded blank, and the blank is transferred to a cavity of a multi-function workpiece fixture controlled by hydraulic driving. On a tray that is vacant in the vertical machining center. After the 12 holes on the workpiece holder are loaded with the blank, the blank is accurately positioned and clamped, and then fed to the machine to start machining.
The protective door of the vertical machining center is opened, the tray switch is positioned, and the jig filled with the workpiece is placed in the processing area for processing. When the machine tool machined the first side of the workpiece, the robot began to install more blanks onto the second vacant pallet clamp. When the first side of the end of the blank is machined, the tray is replaced again. The robot removes the first surface of the workpiece from the first pallet, then transfers it to the "flap station" inside the robotic shield, and then installs it from the inner panel to the workstation and through the workstation The workpiece is effectively turned over with the unmachined side facing up and clamped onto the fixture again for clamping.
After the first 12 parts that have been machined are loaded into the fixture again, the tray changes position again, and then the second side of the workpiece is processed. The parts on the pallet are now fully machined, but the pallet needs to be repositioned so that the robot can remove the part from the pallet.
However, before the robot removes the machined parts, the high-speed compressed air nozzle mounted on the base of the robot clamp is used to blow off the chips left on the entire fixture, because some chips may be removed during the removal of the parts. Drop into one or more holes, affecting the correct placement of the next batch of workpieces. It takes about 30 minutes from the first side of the blank to the complete machining of the part until the finished product is transferred to the next area.

Flange is also called flange plate or flange plate.
The part that connects pipes to each other. Connect to tube end. There are holes on the flange, and bolts can be threaded to make the two flanges tightly connected. The flange is sealed with gasket.
