Single point robotic welder
20 February 2019
ATM Automation has recently expanded its range of welding equipment for the automotive industry to includes a single point robotic welder with sliding nests and hot air cold stake (HACS) machine with poke yoke checks.
The new welder uses a 6 axis robot to weld and clip the part, the operator loads the components into the nest and starts the cycle whilst loading the clips into a draw system. Once the draw system has been loaded and closed, the robot picks up the clips one by one and inserts onto the part and then performs the boss welds. Poka yoke checks ensure the machine verifies that all the clips and welds are OK before releasing the parts and printing a label which the operator scans.
The new HACS machine has been improved to include poke yoke checks to ensure that no faulty parts make it through the car production process. The operator loads the parts and starts the cycle, once the machine has confirmed the presence of all the clips and parts, if there are any parts missing the entire cycle will be aborted to ensure the eradication of defective parts. The nesting moves back to the heater station which heats all stakes.
If there are any parts missing the entire cycle will be aborted to ensure the eradication of defective parts. Once the heating cycle is complete and the part is moved forward again where all the stakes are formed. The nest then returns to load position so the operator can then remove the component and restart cycle.
Both machines have the ability to run through ATM’s BuildAssist control system with the option of OEE and MES software. Both technologies show decision makers the productivity of their shop floor, seeing the overall truly productive manufacturing time is the best way to identify the percentage of defective parts.
