Description

Semiconductor package loading apparatus {Semiconductor package loading apparatus}

The present invention relates to a semiconductor package loading apparatus, and more particularly, to an apparatus capable of automatically loading a package loaded on a tray into a tube.

Semiconductor packages singulated from leadframes during the semiconductor manufacturing process are loaded into trays or tubes at the type of semiconductor or at the request of the orderer.

For this reason, devices that singulate semiconductor leadframes include tray-type off-loaders that load packages into trays, tube-type offloaders that load tubes, and trays and tube types that can be selectively loaded into tubes and trays. Off loaders are provided.

Typically, a semiconductor package manufacturer subcontractor delivers the package to a tray or tube according to the orderer's request as described above. A subcontractor with only a singulation device equipped with a tray-type offloader is required by the orderer to deliver the package to the tube. In the case of requiring the loading, the requirements of the device could not be satisfied because the package could not be loaded only in the tray.

Therefore, a semiconductor manufacturing subcontractor may purchase a singulation device equipped with a tube type offloader or manually load a package loaded in a tray into a tube in order to satisfy the demand of an ordering company. This leads to an increase in material burden, and a lot of difficulties arise in the work given the small size and large number of packages.

It is an object of the present invention to provide a simple low-cost semiconductor package stacking device capable of exclusively loading a package loaded on a tray into a tube.

However, the tray feeder 42 may move to the package unloading position 34 without rotating the tray feeder 42 depending on the orientation of the package placed on the tray 5. In this way, the tray 5 does not rotate or not, after the operator recognizes the direction of the package 1 seated on the tray 5 in advance and determines the direction of the package 1 to be loaded on the tube 60, and then the tray feeder. It is determined by inputting the rotation angle of 42 to a control device not shown in advance.

Thereafter, the tray feeder 42 moves the package unloading position 34 in a state in which the tray 5 containing the package 1 is loaded. When the tray feeder 42 is moved to the package unloading forge 34, the package picker 50 is moved downward by the package picker vertical transfer member 53, and at the same time, the package is picked up by the operation of the solenoid valve 56. The negative pressure acts on the picker to allow the package 1 to be adsorbed to the tray 5 in a desired quantity. The package picker 50 is lifted up again by the package picker up-and-down conveying member 53, and in this state, the package picker 50 is moved vertically upward of the chute 62 by the package picker horizontal transfer means 54. It is moved to the position. Thereafter, the package picker 50 is lowered again by the package picker vertical transfer member 53, and the package 1 is seated by the operation of the solenoid valve 56 on the seating portion 63 of the chute 62. Let's go.

When the package is seated on the seating part 63, the cover 67 is rotated by the cylinder 66 to cover the seating part 63 so that the package 1 can be detached from the seating part 63 of the chute 62.
