Abstract
A method by which the height of an electronic component sucked and held by a nozzle can be detected with high accuracy and high efficiency is a component height measurement method applied to a mounter (100) equipped with a transfer head (8) having a component-sucking-and-holding nozzle (21), for transferring a component P and mounting the component P onto a board (3), and includes: lowering the component P to within the high-accuracy range of a first line sensor (13) for measuring the height of the component P; and measuring the height of the component P using the first line sensor (13).
Claims7
A component height measurement method applied to a mounter equipped with a transfer head having a component-sucking-and-holding nozzle, for transferring a component and mounting the component onto a board, said method comprising:
- tentatively lowering the nozzle and the component sucked and held by the nozzle, and tentatively measuring a height of the component using an amount of said tentative lowering of the nozzle and a signal outputted from a line sensor for measuring the height of the component, the line sensor being disposed laterally relative to the nozzle and extending vertically along a direction of movement of the nozzle;
- lowering the component to within a high-accuracy range of the line sensor, based on the height of the component measured in said tentative measuring;
- and
- definitively measuring the height of the component using the line sensor.
A component mounting method applied to a mounter equipped with a transfer head having a component-sucking-and-holding nozzle, for transferring a component and mounting the component onto a board, said method comprising:
- tentatively lowering the nozzle and the component sucked and held by the nozzle, and tentatively measuring a height of the component using an amount of said tentative lowering of the nozzle and a signal outputted from a line sensor for measuring the height of the component, the line sensor being disposed laterally relative to the nozzle and extending vertically along a direction of movement of the nozzle;
- lowering the component to within a high-accuracy range of the line sensor based on the height of the component measured in said tentative measuring;
- definitively measuring the height of the component using the line sensor;
- and
- mounting the component onto the board based on the definitively measured height of the component.
