CARLSBAD, Calif, Nov. 29, 2017 (GLOBE NEWSWIRE) -- Programmable electric actuators have been increasingly favored as airless substitutes for LVDT’s and ball screws in connector pin insertion and connector pin height measurement, reports SMAC. Unlike ball screws or LVDT’s, electric actuators have programmable positioning. They can press the pin in with the correct force, verify its position, and provide a tight fit every time.
This change has been spurred by increasing dependency on critical electronics in a variety of industries. The automotive industry, with its need for 100% quality, has seen some of the greatest change. A misalignment of even a single pin in an automobile can result in recalls, layoffs and a wide-spread loss of consumer trust. A missing signal could ruin a car, a series of cars and/or an entire system.
Manufacturers need to fit contact pins into PCB boards with high speed and have the optional ability to choose orientation. They need a fast and flexible solution with 100% quality. For example, an automotive manufacturer wanted to replace a ball screw and LVDT arrangement, which was the slowest part of the process in their testing machine. In addition, the spring loaded LVDT did not offer repeatability that they were looking for. They needed devices that are high speed and precise with flexibility in programming.
Many manufacturers have adopted programmable electric actuators, like SMAC Moving Coil Actuators, for its high speed, high precision, and flexible programming. SMAC electric actuators have programmable velocity, position and force, and the ability to give feedback on the work being done, while it is done. To measure the height of pin, SMAC uses a patented Soft-Land function. The Soft-Land function is a patented unique routine which allows the actuator rod to land on the surface of a component with a low programmed force. It gives extremely accurate sensing of product location or dimensions. This is particularly useful for handling delicate or high value components.
A similar method could be used for thread checking, dimensional inspection, or anything that needs 100% inspection, especially in automotive where quality is key.
