Low-Cost, High-Speed Assembly Robot
A low-cost delta or “spider” robot for high-speed assembly and pick-and-place tasks is newly available.
igus Inc., E. Providence, R.I., says the low-maintenance, lightweight unit starts at $6200. It can be delivered preassembled or can be assembled on-site in about 30 min with easy-to-use instructions, the company says.
Stepper motors and encoders ensure accuracy to ± 0.5 mm. Built of aluminum and plastic, the unit weighs 15 kg (33 lb) and occupies an installation space of 420 mm diam. It can carry up to 5 kg (11 lb) at low speeds. Maximum pick rate is 60/min. Max. speed is 3 m/sec.
There is no “one size fits all” solution in automation. When considering what it would look like in your plant, hone in on the staff, products, space, and goals that are specific to you and the automation system that you will be installing.
Injection molded parts are typically demolded with simple pick-and-place automation—a top-mounted, gantry-style (also called Cartesian, linear, or traversing) three-axis robot.
With so many choices available today, it’s important for molders to understand the pros and cons of Cartesian vs. articulated-arm robots and how their capabilities overlap more than ever before.
