For these reasons, a semiconductor sensor is the most. To efficiently withdraw information from numerous sensors and to minimize wirings from the sensors, it is necessary to install a switching circuit on each sensor.
In particular, a tactile imager with a high density of pressure sensors must be developed. To realize a robot with a high degree of functions, pressure sensors are essential. Engineers should discuss the ingredients and variables that operators need to consider before switching off a CFM. There are a lot of ingredients and if one ingredient is missing or of bad quality, you likely are not going to achieve your desired result. Crimp quality detection is similar to baking a cake. However, to create products with the highest quality and reliability, engineers, like chefs in the kitchen, need to ensure each ingredient in the process is properly prepared before sending it out to the assembly line. All CFMs come with base parameters that work for many applications. Several variables need to be evaluated and understood for successful use of a crimp force monitor (CFM). After reference crimps are made, each subsequent crimp is compared to the reference crimp and the specified tolerance, resulting in a good or bad output. The devices use a piezoelectric sensor to detect crimping forces. Different applications require different CFM parameters and operators need to learn to interpret the feedback from the CFM to determine where the variation occurred and if that variation really constitutes a “bad” crimp.Crimp force monitors allow wire harness assemblers to improve quality and boost productivity. But, since this does not fit in the CFM’s display screen, it is simply called a “bad” crimp.
Therefore, in CFM terms, “bad” really means the actual crimp curve is outside of the tolerance range that was defined from the known good crimps during the “teach-in” process. The CFM then compares all future crimps to this data. This consists of running several crimps and manually verifying that the data associated with that crimp (crimp force, crimp height, etc.) is correct. The CFM considers any variation outside of the programmed tolerance a “bad” crimp.Īn operator must teach the CFM what to identify as a good or bad crimp through the “teach-in” process. The main function of a CFM is to be a process monitor and to detect variations along the crimp force signature curve that are outside of the programmed tolerances. What can a CFM actually detect? A general assumption within the industry is that crimp force monitoring will provide reliable detection of all general crimping errors during processing, including:īut, simply plugging in a CFM will not solve all their crimp quality issues.
