Description

one

The invention relates to the field of automatic loading of parts of semiconductor devices in cassettes.

Closest to the present invention is a device for stacking objects in a container containing a feeder for objects, a copier and a channel for accumulating objects with a movable support 1.

The disadvantage of this device is that when moving objects forward along the channel, the movable stop advances with them, loses contact with the objects that are moved apart, which receive voluntary movements, and there is the possibility of inaccurate items falling into the cassette cells.

The known device is unacceptable, for example, for the case of distributing objects located on a vibrating channel or on an inclined plane.

The aim of the invention is the elimination of arbitrary non-displacement of objects in the course of their supply, which prevents an increase in productivity and an increase in the reliability of the process of loading objects.

This is achieved by the fact that in the proposed device for laying iredmetov the copier is mounted with the possibility of perpendicular movement to the longitudinal axis of the channel,

at the same time, the working surface of the copier is positioned in such a way that it is in contact with the movable stop and is inclined to the longitudinal axis of the channel so that the uior can move at a speed corresponding to the speed at which objects are fed into the channel.

On fng. 1 shows the proposed device, a general view; in fig. 2 is a section A-A in FIG. one.

A device for laying the items in cassettes consists of a base 1, on which are attached 2 of a feeder 3 with loadable parts 4, a guide channel 5 for accumulating parts, formed by a ledge 6 and folding supports 7, rotating around a common base 8, which is mounted on the uprights 9. The cams 10, made in conjunction with combed.m pusher 11, moving

in the guides 12 perpendicularly to the longitudinal axis of the channel 5, designed to divert, through the role 13, the stops 7, which are spring-loaded with springs 14. Conir 15 is attached to the comb pusher 11,

interacting via roller 16 with an iodine stop 17. Downloadable parts 4 push the ledge 18 to the loading windows 19, through which they fall into the cassette 20.

In this case, the working surface of the copier 15

is positioned in such a way that it is in contact with a movable stop and is inclined to the longitudinal axis of the channel 5 so that the stop can move at a speed corresponding to the speed at which objects are fed into the channel 5.

The device works as follows.

The required number of loaded parts 4 comes close to each other in the guide channel 5 before contact with the movable stop 17 (Fig. 1). The comb plunger 11, moving in the guides 12, enters the first, most prominent tooth between the parts, cuts off the necessary number of parts from the feeder 3 and pushes them in the guide channel 5 by the thickness of the tooth. At the same time, the copier 15 enters contact B with the movable stop 17 and, through the roller 16, moves it back by the same amount as the moved apart parts, thereby ensuring constant contact with them. When the sliding of the first part is smoked between the teeth of the comb pusher, the cam 10 raises the stop 7 by means of the roller 13 and with the further comb pusher the part is pushed by the ledge 18 to the loading window 19 through which it enters the cassette 20 (Fig. 2). The next comb tooth pushes the remaining parts, etc. After the loading cycle is completed, the pusher returns with the movable stop to its original position and the loading cycle repeats.

Thus, thanks to the proposed device, it is possible to increase the productivity and increase the reliability of the process of loading objects by eliminating their voluntary movement while increasing the loading speed.

FORUMY: i a invention

A device for placing objects in cassettes containing a feeder for objects, a copier and a channel for accumulating objects with a movable stop, characterized in that, in order to increase the reliability of operation, the conier is installed with the possibility of being displaced perpendicularly to the longitudinal axis of the channel, and this is positioned in such a way that it is in contact with a movable stop and is inclined to the longitudinal axis of the channel so that the stop can move at a speed corresponding to the speed at which objects are fed into the channel.
