Abstract
During mounting of an upper component on a lower component, after mounting the lower component on a board, the Z-axis position of a suction nozzle tip is detected during mounting of the lower component on the board and memorized as a lower component height, and when mounting the upper component PU, the suction nozzle is lowered at relatively high speed until reaching a specified position that is a distance above the lower component height, and the suction nozzle is lowered at a speed that is slower than the speed after arriving at the specified position until contact with the lower component.
Claims5
A component mounter for mounting multiple components in a stack on a board, the component mounter comprising:
- a head including a holding member configured to hold the component;
- a raising and lowering device configured to raise and lower the holding member;
- a raising and lowering position detector configured to detect a raising and lowering position of the holding member;
- a contact detector configured to detect that the component held by the holding member has contacted a mounting target object;
- and
- a controller configured to acquire, when a former component among the multiple components to be stacked on the board has been mounted and contact of the former component to a mounting target object is detected by the contact detector, position information of the former component identified based on the raising and lowering position of the holding member detected by the raising and lowering position detector, and configured to control the head and the raising and lowering device so as to, when mounting a latter component among the multiple components to be stacked on the board, mount the latter component on the former component based on the acquired position information of the former component.

A component mounting system comprising:
- a first component mounter configured to mount components on a board;
- and
- a second component mounter arranged downstream in a mounting line with respect to the first component mounter and configured to stack and mount a component on an upper surface of a component mounted by the first component mounter;
- wherein
- the first component mounter includes
- a first head including a first holding member configured to hold the component,
- a first raising and lowering device configured to raise and lower the first holding member,
- a first raising and lowering position detector configured to detect a raising and lowering position of the first holding member,
- a first contact detector configured to detect that the component held by the first holding member has contacted a mounting target object,
- a first controller configured to control the first head and the first raising and lowering device such that a former component among the multiple components to be stacked on the board is mounted on the board, and
- a transmitting means configured to, when mounting the former component, transmit directly or indirectly to the second component mounter position information of the former component identified based on the raising and lowering position of the first holding member detected by the first raising and lowering position detector when the first contact detector detects that the former component has contacted the board, and
- the second component mounter includes
- a second head including a second holding member configured to hold the component,
- a second raising and lowering device configured to raise and lower the second holding member,
- a second raising and lowering position detector configured to detect a raising and lowering position of the second holding member,
- a receiving means configured to receive directly or indirectly the position information of the former component transmitted from the first component mounter, and
- a second controller configured to control the second head and the second raising and lowering device so as to mount a latter component among the multiple components to be stacked on the board on the former component based on the received position information of the former component.
