Abstract

PURPOSE:To stack a number of trays without causing horizontal and vertical disengagement from one another to facilitate the storage and transportation thereof or permit the setting thereof on an automatic mounting device. CONSTITUTION:The sides of each tray 1 are provided at the upper and lower parts thereof with interengageable raised edges 3 and depressed edges 4 to prevent each adjacent tray 1 from lateral movement and at least a pair of opposed sides of each tray are provided with interengageable locking pieces 13 to interlock each adjacent tray 1. When the trays are set on an automatic mounting device, the locking pieces 13 are released easily by pressing the trays in the lateral direction. This prevents the disengagement of the trays 1 from one another and hence the falling off of an electronic component and the bending of the lead. Morever, the attachment and detachment of the individual trays is easy in the automatic mounting device.

It is characterized in that it is provided with a releasing piece portion for releasing the locking between and.

Further, a large number of surface-mounting electronic parts are provided in a characteristic inspection handler which takes out the surface-mounting electronic parts one by one from the surface-mounting electronic part tray containing a large number of surface-mounting electronic parts and performs a characteristic inspection. It has a locking piece release claw for pressing and releasing the locking pieces of trays set by stacking a plurality of the stored surface-mounted electronic component trays, and the vertical direction is regulated by releasing the locking pieces. A tray transport arm for transporting the released tray to the component take-out section, and one electronic component is taken out from the tray carried to the component take-out section and transported to the inspection head, and at the same time the electronic parts for which inspection has been completed are stored in the storage section. And a component transfer arm for transferring to a tray.

[0014]

When another tray is stacked on the tray, a convex edge protruding in the stacking direction is formed on the lower surface of the side edge of the tray, and a convex edge is formed on the upper surface of the side edge of the other tray in the stacking direction. The recessed edges are fitted to each other, and the upper and lower trays are restricted from moving relative to each other in the lateral direction. At the same time, locking pieces formed on the side faces of the pair of opposite sides of the tray in the direction perpendicular to the stacking direction and on the side faces of the pair of opposite sides of the other tray corresponding to the direction perpendicular to the stacking direction. It locks with the locking piece and regulates vertical movement.

This fitting and locking are sequentially performed on the trays to be stacked, and a large number of trays are fixed in a state in which the vertical and horizontal movements are restricted. By setting in the automatic mounting device or the characteristic inspection handling device, and by pressing the release piece portion provided in the locking piece from the lateral outside by the locking release arm mechanism provided in the automatic mounting device or the characteristic inspection handling device, The locking of the locking piece is released. After releasing the locking of the locking piece, the engagement of the convex edge and the concave edge is released by raising the locking piece releasing arm,
The tray is transported to the subsequent mounting work or inspection work position.

As a result, it is possible to prevent the parts from popping out due to the displacement of the tray 1 and the leads from bending due to dropping.
