Electronic component mounting system
A system for mounting electronic components on a substrate includes component holders each configured to hold an electronic components to be mounted on the substrate. A revolving device is configured to revolve the component holders along a pre-determined path so that each one of the component holders is moveable into a component receiving location for receiving a respective electronic component and/or a component mounting location for mounting the respective electronic component on the substrate. An actuator is configured to actuate a respective component holder in the component receiving location and/or the component mounting location. A safety device is configured to determine whether the respective component holder to be actuated by the actuator is properly placed in an operative position on the revolving device. The safety device is arranged separately from the actuator and is spaced apart from the actuator along the pre-determined path.
1. A system for mounting a plurality of electronic components on a substrate, comprising:
a plurality of component holders each configured to hold at least one of the electronic components to be mounted on the substrate,
a revolving device configured to revolve the component holders along a pre-determined path so that each one of the component holders is moveable into at least one of:
a component receiving location for receiving a respective one of the electronic components, or
a component mounting location for mounting the respective one of the electronic components on the substrate,
an actuator configured to actuate a respective one of the component holders in the at least one of the component receiving location or the component mounting location, and
a safety device comprising a mechanical position detector configured to mechanically screen a position of the respective one of the component holders on the revolving device so as to determine whether the respective one of the component holders to be actuated by the actuator is properly placed in an operative position on the revolving device, the safety device being arranged separately from the actuator and being spaced apart from the actuator along the pre-determined path, wherein the safety device comprises a movable part configured to be moved by engagement with a circumferential projection or a cutout of the respective one of the component holders which is not properly placed in the operative position.
2. The system according to claim 1 , wherein the safety device is arranged separately from the actuator in such a manner that operation of the actuator during actuation of the respective one of the component holders is not impaired by the safety device.
3. The system according to claim 1 , wherein the safety device is spaced apart from the actuator in such a manner, and is configured such that, a position of the respective one of the component holders is determinable by the safety device before the respective one of the component holders reaches the actuator during a revolution of the revolving device.
4. The system according to claim 1 , wherein the safety device is arranged adjacent to the actuator.
5. The system according to claim 1 , wherein the respective one of the component holders is designed to return to the operative position after actuation by the actuator.
6. The system according to claim 1 , wherein the component holders are mounted on the revolving device so as to be movable up and down along an axis of rotation of the revolving device.
7. The system according to claim 6 , wherein the component holders are designed to return to a level along the axis of rotation corresponding to an operative position of the component holders.
8. The system according to claim 1 , wherein the safety device comprises a position detector.
9. The system according to claim 1 , wherein the movable part is formed by a lever that is swivel-mounted on a base body of the safety device.
10. The system according to claim 1 , further comprising a sensor configured to detect the movement of the movable part.
