Flow path rail seat and image detecting device using the same

The present invention relates to a flow path rail seat and an image detecting device using the same, and more particularly to a flow path rail seat for carrying a carrier on which a plurality of electronic components are arranged in a matrix, and using the same Image detection device for the flow rail seat.

According to the general micro-components, the electronic components are often used in the processing process to use a carrier tray in which a plurality of electronic components are arranged in a matrix. The carrier is usually in the form of a rectangular sheet, which is usually used for automation. It is conveyed in a first-class rail seat. In addition to providing the function of transporting the carrier, the runner rail seat also provides a positioning function for the processing of the carrier on the carrier; the general runner rail has two parallel rails forming a track. The shelf and the two rails are spaced apart from each other and are provided with a flow path belt extending the length of the entire track, so that the transported carrier is located on the flow path belt and is transferred or positioned between the entrance and exit ends of the two tracks; When positioning in the belt, a fixture is usually arranged between the two rails, and the carrier is positioned on the fixture by the operation of the fixture to process the plurality of electronic components carried on the carrier.

In the prior art, when the carrier is required to be almost equal in length, width and area according to the processing needs, it is generally located below the flow path of the flow path belt to sense the sensor in which the carrier is transported into position. The sensing signal will be blocked by the fixture and it is not easy to detect that the carrier is in place, so that the carrier is often over-transported and removed from the fixture, so that the plurality of electronic components carried on the carrier are detected. When processing, the accuracy is prone to errors and the correction procedure must be added. In addition, the prior art often requires an elastic element to be stopped from the side of the rail to the rail between the two rails when the carrier is in place. The center of the ventral side of the carrier is pushed to make the carrier position stable and easy to process. However, the single point positioning is not only easily displaced by the displacement and vibration of other mechanisms of the machine, but also the elasticity of the elastic pushing. It is easy to loosen the elastic fatigue due to too many operations; because the accuracy of the above detection and positioning is difficult to control effectively, the existing flow rail seat can be applied to, for example, dispensing and packaging, but the flow rail is applied to the AOI.
