Title:
LOAD MEASUREMENT DEVICE AND LOAD MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/077594
Kind Code:
A1
Abstract:
The present invention suppresses incorrect measurement when measuring a pressing load. A load measurement device 81 is equipped with a load sensor 95, a data logger 97, and a measurement start switch 99, which are provided inside a housing 83. The load sensor 95 outputs a detection voltage V2 corresponding to the size of a pressing load to the data logger 97, when a suction nozzle of a mounting device presses down on a switch 95A. The data logger 97 records the detection voltage V2 for only a prescribed interval from the timing at which a high-level recording start signal S2 is inputted from the measurement start switch 99. As a result, the data logger 97 does not store the detection voltage V2 during the interval until the high-level recording start signal S2 is inputted from the measurement start switch 99, and consequently, does not incorrectly store vibrations and the like during transport as a load.
