SMAC 55 Adjusting Thermostat by Iterative Sensing and Correction Actuators: LAL-30 Stroke (mm): 25 Resolution: 1 or 5 micron Force: 10 newtons Moving Mass: 150 gms Supply Voltage: 24 Volts Bimettalic element TOP VIEW A thermostat turns on when two contacts come together. One of the contacts is a bi-metallic element which changes position with temperature. The gap between the contacts needs to be set so when the set temperature is reached, the gap will close. The gap is set by positioning the bi-metallic contact using the desired temperature setting and then "bending" the other contact. Since metallic leaf spring elements have memory, the contact needs to be "bent", recheck and then "bent" again in an iterative process until the gap is in the right position. To speed this up in an automatic thermostat assembly line, this customer has worked out a process method that uses a continuous measurement (vision system) that would determine the next "bending" position based on the measured position. SMAC actuator & controller combination provides this solution by accepting a new target data point in servo positioning loop. Other Applications: Dispensing solder paste. Amount dispensed varies with viscosity, temperature, humidity, etc. By sensing the amount dispensed a new setting can be entered into the SMAC controller to compensate for parameter variations Key Operational Details: High speed approach, slow down, softland on contact, gap is measured to determine next position Element bends down as temperature rises SIDE VIEW Gap = 0 at set temperature SIDE VIEW DISTANCE Position is used as new target, gap is measured, new position is determined Actuator rod retracts and final gap position is checked SMAC Advantages: Continuous closed loop operation results in higher speed operation in automatic assembly line. Interrupt driven servo program allows new target data to be input and set in the middle of a motion profile SMAC •5807 Van Allen Way •Carlsbad, California 92008•Fax: (760) 929-7588 •Tel: (760) 929-7575 TIME
SMAC 56 LAL-30 Part to be Assembled LAL-30 Switch Assembly & Test Many manufacturing organizations are aiming to achieve six sigma as a demonstration of the high quality of their products. One method is to perform 100% inspection of all subassemblies. An automotive switch manufacturer has designed an assembly fixture using an SMAC actuator that would assemble the switch and measure the force and stroke to activate the switch. Other Applications: Inserting pins or sockets into connectors Actuators: LAL-30 Stroke (mm): 25 Resolution: 1 or 5 micron Force: 10 newtons Moving Mass: 150 gms Supply Voltage: 24 Volts Key Operational Details: High speed approach, slow down, softland on part, signal if component is missing, if not, ramp force up to press component into body of switch Retract to positon above switch to do the go/no go test Soft land on switch, register starting postion, apply force to turn on switch, register stroke and force at "on" position Apply go/no go window to test results, accept or reject switch. SMAC Advantages: Switch is assembled, tested and verified in one operation SMAC actuators are ready to mount and programmed After assembly part can move in/out to test SMAC •5807 Van Allen Way •Carlsbad, California 92008•Fax: (760) 929-7588 •Tel: (760) 929-7575 MOTION PROFILE
