In-situ quantification of manual assembly forces and postures during the manufacture of TV deflection coils.
A system is described which has been developed to meet an industrial requirement for performing in-situ quantitative measurements of manual forces and postures applied by human assembly line operators.
Virtual reality devices are shown to offer a valuable means of meeting the necessary sensory requirements.
The instrumentation is also seen to satisfy the requirements for a generic force and posture measurement system applicable to most human assembly operations in manufacture.
A set of force transducers incorporated into a pair of Datacq gloves together with a force triggered image capturing facility, all controlled by a PC compatible, comprise the main hardware elements of the basic system.
The instrument software provides on-line force and posture data capture facilities, which allows quality control staff to assess the way the operator undertakes the assembly process, including maximum forces applied and a measure of the effort or work done per assembly cycle.
The full data recording may be reviewed, zoomed and edited using a playback mode, allowing the observer a convenient way of assessing risk in undertaking an assembly operation since both the phalange forces and the wrist posture for a particular assembly operation are measured quantitatively.
Results are presented for a representative electronics assembly task involving the assembly of TV deflection coils using operators employed by a U.K. manufacturer. (...)
