Abstract

Riešenie sa týká zariadenia na vyhadzovanie a zakladanie najma puzdrených súčiastok z paliet, v ktorých sú súbory týchto sú čiastok počas puzdrenia uložené. Zariadenie pozostáva z tandemového valca tvořeného horným valcom a spodným valcom. Piestnica spodného valca je upevněná na držiaku spojeného s konzolou. K veku horného· valca je připevněný nosný rám, v ktorom sú prestavitelne uložené kuželové hroty. Na piestnicu horného· valca je uchytená doska s vyhadzovacími telesami.The solution relates to a device for ejecting and loading, in particular, encapsulated components from pallets in which sets of these components are stored during encapsulation. The device consists of a tandem cylinder formed by an upper cylinder and a lower cylinder. The piston rod of the lower cylinder is mounted on a holder connected to a console. A supporting frame is attached to the lid of the upper cylinder, in which conical tips are adjustable. A plate with ejector bodies is attached to the piston rod of the upper cylinder.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for ejecting and setting up particularly encapsulated components, such as various types of integrated circuits and transistors from pallets in which sets of these components are stored during encapsulation.

When encapsulated, the components are covered with a sheathing material and after curing it is necessary to remove them from the pallets. Since encapsulated files proceed to further machine processing, it is necessary that the entire apron be removed as intact as possible. Until now, simple aids (screwdrivers, ratchets, tweezers) have been used to remove the encapsulated components. A very unfavorable factor for manual removal is the high temperature of the pallets (up to 170 QC) and also the low level of work. The disadvantage is that manually removing the encapsulated components is not suitable for automating the encapsulation process.

The aforementioned drawbacks are eliminated by a device for ejecting and setting up particularly packaged components, the essence of which is that it consists of a tandem cylinder formed by an upper cylinder and a lower cylinder. The lower cylinder piston is mounted on a bracket attached to the bracket. A support frame is attached to the top roller lid, in which the tapered tips are adjustable. The ejector plate is attached to the upper cylinder piston rod. The advantage of the device for ejecting and setting up the most encased parts is that the device can be used in mechanized, automated plants as well as in manual semi-automatic devices for encapsulating parts.

A device for ejecting and setting up the most encapsulated components is shown in the accompanying drawing, in which, in FIG. 1, the device is shown in a partial cross-section; FIG. 2 shows a detail of a pallet with encapsulated parts; and Fig. 4 is a detail of the pallet a

SUBJECT

A device for ejecting and loading most encapsulated components, characterized in that it consists of a tandem cylinder (18) formed by an upper cylinder (2) and a lower cylinder (1), the piston rod (3) of the lower cylinder (1) being mounted on the holder (4) the jettison body in the file creation position.

The device for ejecting and loading the most encapsulated components consists of a tandem roller 18 formed by an upper roller 2 and a lower roller 1. The lower roller 1 piston 3 is mounted on a bracket 4 connected to the bracket 5. A support frame 7 is attached to the piston rod 9 of the upper cylinder 2, in which the conical studs 8 are adjustable. The piston rod 9 of the upper cylinder 2 is fitted with a plate 10 with ejectors 11, in which the seats 17 are formed. for encapsulated components 13.

The function of the ejection and loading device of the most encapsulated components is as follows:

The pallet 12 with the encapsulated components 13 is transported to the loading and unloading position by means of a support chain 14 mounted on the guide rails 15, where it stops. Here, a tandem roller 18 is actuated which lifts the entire mechanism of the ejection and loading device of the encapsulated components. During lifting, the pallet 12 freely supported on the support chains 14 is seated on the tapered tines 8 on which it is lifted up to the stops 16 to prevent it from being lifted further. In this position, the edges of the ejector bodies 11 are supported on the outlets of the encapsulated components 13 and the seats 17 in the ejector bodies 11 are supported on their lower surfaces.

Upon actuation of the tandem roller 18, the ejector plate 10 begins to eject the encapsulated components from the pallet 12. After they have been pushed and removed, the plate 10 returns to its initial position and the pallet 12 is ready for further loading of the assemblies (Fig. 3). After its foundation, the support frame 7 is lowered to the starting position, whereby the pallet 12 is placed on the support chains 14 and is thus again ready for the encapsulation process.

INVENTED with the bracket (5), while a support frame (7) is attached to the lid (6) of the upper cylinder (2), in which the conical tips (8) are displaceably mounted, while the piston rod (9) of the upper cylinder (2) a plate (10) with ejector bodies (11) is mounted.
