Abstract

The invention provides a compact surface mounter capable of fast executing carryout detection of a sucking nozzle while suppressing damage to the sucking nozzle. A head unit 3 comprising a sucking nozzle for sucking an electronic component C displaces relative to a stage 2 on which a printed board P is placed, so that the electronic component C sucked by the sucking nozzle is mounted on the printed board P. The surface mounter comprises a support member 10 which supports the head unit 3 on the stage 2 so that the head unit 3 can displace along the X axis, a side camera capable of imaging the sucking nozzle sideways, on at least either the head unit 3 or the support member 10, and a controller for judging whether a component is sucked to the lower end part or not based on the side image of the electronic component C after the electric component is released.

Description

Technical field [0001] The present invention relates to a surface mounter that mounts electronic components such as IC chips on a printed wiring board. Background technique [0002] A generally known surface mount machine is a surface mount machine that is driven between an electronic component supply unit and a printed circuit board through a head having a suction nozzle, and the electronic components sucked by the supply unit are transported to the printed circuit board and mounted . [0003] Some surface mounters of this type can detect whether electronic components are left (whether the electronic components are brought back) on the nozzles that should have electronic components installed (for example, Patent Document 1: Japanese Patent Laid-Open No. 11-346100 No. disclosed electronic component mounting machine). [0004] The electronic component mounting machine has a sensor fixedly mounted on its main body, which can detect whether there is a suction nozzle at the lower end...

Problems solved by technology

[0005] However, in the electronic component mounting machine of the above-mentioned Patent Document 1, as the sensor is fixedly mounted on its main body, the detection position on the main body is limited, so the movement of the head required for detection is made according to the current position of the head. The longer the distance, the longer the time required to move the head, and as a result, the workability of the installation work is often deteriorated.

[0006] Therefore, it is also considered to install a plurality of sensors on the main body, but in this case, the proportion of the area occupied by the sensor on the main body increases, and the area of ​​the main body needs to be enlarged accordingly, so the area of ​​the mounting machine itself is enlarged.

[0007] Moreover, in the electronic component mounting machine of Patent Document 1, since the sensor is arranged on the return path (moving path) of the head, if an erroneous operation of the head occurs, the suction nozzle may collide with the sensor and the sensor may be damaged. Damaged nozzle
