The invention relates to a technique of supplying radio components, in particular to devices for the orientation of semiconductor devices with one-sided leads, mainly transistors.

The purpose of the invention is to expand the operational capabilities of the device by ensuring the orientation of semiconductor devices with low mass and simplifying its design.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; on fig.Z - various positions of the semiconductor device during orientation; in fig. 4 - device with a horizontal semiconductor device on the tray; in fig. 5 is a view B in FIG. four.

A device for orienting semiconductor devices comprises an output vibration tray 2 connected to the vibrobunker bowl 1 with a longitudinal groove 3 for the passage of devices, a guide 5 is mounted on the side wall 4 of the tray, with a guiding ledge 6 on its lead-in section and a straight edge 7 located parallel to the longitudinal axis of the tray. The rectilinear guide edge 7 and the protrusion 6 are located under the bottom of the longitudinal groove 3. The top 8 of the protrusion 6 is disposed relative to the rectilinear guide edge 7 towards the side wall of the tray 2 opposite to it. The protrusion 6 of the guide 5 is made with a lead-in bevel 9 from its top 8 to side wall 4 longitudinal groove of the tray.

The device is intended for the orientation of semiconductor devices with one-sided leads, mainly transistors 10, the terminals 11 of which are located at the vertices of an isosceles triangle, the distance between the terminals 12 and 13 is equal to the distance between the terminals 13 and 14 and less than the distance between the terminals 12 and 14. The terminals 12 and 14 are located in the median plane of the cylindrical body of the transistor 10.

Russ toyangne between rectilinear

the edge 7 of the guide 5 and the side opposite to the side of the groove 3 of the tray 2 is such that

in the gap between them the transistor can

be in a position where the pins 12 and 14 are located in a plane parallel to the longitudinal axis of the tray 2.

The entry bevel 9 of the protrusion 6 is performed at an angle of 30-40 ° to the longitudinal axis of the tray 2.

The device works as follows.

Transistors 10 come from the vibrating hopper bowl 1 into the tray 2 so that the transistor case is located in the longitudinal slot 3, while moving along the tray 2 transistors rotate around its axis due to the tangential arrangement of the tray 2 relative to the vibrating hopper bowl 1 (Fig. 1).

Reaching the runway 9 of the protrusion 6 of the guide 5, the transistors 10 pass the tip 8 only in one position (terminal 14 forward) and eττμ are held in the oriented position with the straight edge 7 of the guide 5. In the oriented position the leads 12 and 14 of the transistor 10 move along the edge 7 If the transistors approach the bevel 9 in an unoriented position, they rotate at the bevel until they turn to pin 14 forward.
