Description

one

The invention relates to the field of radio electronics, in particular to devices for stacking core parts of small diameter in a cassette.

Devices are known for loading core parts into a cassette comprising a vibrating hopper with rare cassettes and a cassette with holes for accommodating the parts. The cassette holder is made in the form of one after another successive grids with cells of different sections 1.

However, in known devices, there is an insufficient filling of the cassette and the oscillation speed of the vibrating hopper is limited, which reduces the productivity and reliability of loading parts.

The aim of the invention is to increase the work performance and reliability of loading parts - by providing a device for loading core parts into a cassette, mainly the semiconductor device terminals, containing a vibrating bunker with a grille, equipped with a partition n placed at the bottom of the vibro bunker and electromagnets installed under the vibrating bin current, the lattice is rigidly connected to the partition and the axis fixed in the walls of the vibrating hopper with the possibility of rotation.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a section BB of FIG.

one; in fig. 5 shows the bottom of the vibrating hopper and the rear wall.

The device includes a plate 1 on which the drive is located, consisting of an electric motor 2, a reducer 3 n a belt 4. The drive through a belt is connected with a crank mechanism 5 with an adjustable but a crank length. On plate 1 on racks 6, two guides 7 are fastened, on which a carriage assembly is mounted, consisting of a bracket 8 connected to a crank-thrust-connecting mechanism 5, two front sliders 9 and two rear 10 connected by strips 11. On the plates there is a vibrating bunker 12, made of non-magnetic material. In the external tank without contact with the bottom, the grid 13 is stopped, the cells of which are rectangular. At the bottom of the vibrator unit, there is a partition 14. The grating 13 is rigidly connected to the partition and the axis fixed in the walls

vibrating hoppers can be rotated. In the rear wall of the vibrating hopper there are a number of windows 15 (see Fig. 5) of arcuate shape. Its bottom has six segment-shaped grooves, which are folded into flat windows in the direction of the windows 15. The lower part of the windows 15 and the bases of the grooves lie in the same plane, thanks to what Oriented parts 16 when moving. the gutters are dropped into the cassette 17, and the unoriented ones are retained by the partition 14. The cassette - is installed in the slots of the sliders 10 (see Figures 3 and 4) onto two adjustable devices - 18 and secured with two screws 19.

Two electromagnets 21 with 22 L-shaped cores, connected to the source of pulsed current, are installed on the nlit 1 under the vibra-bin 12 in the corus 20 (see Figs. 1 and 2).

The device works in the following way.

A portion of the chaotically coupled parts 16 (skon) is fed to the grid 13 of the vibrobouker 12 and include the device. The vibro-bunker oscillates on the guides 7, as a result of which the scopus on the grating starts to collapse and the bottom of the vibrator buoyer drops both individual parts and small portions. Separately dropped parts during one or two vibrations of the vibrating hopper are oriented and through windows 15 iod by the action of mechanical forces and forces iercine flies out into the cassette 17. Parts that have fallen together on the bottom of the vibrating hopper are in various positions. The impulse supplied periodically by electromagic 21 captures and removes the parts that are in the active zone of the electromagnetic impulse from the moving inertia force scopes and puts them into the channels. When the cassette is full of parts, the device turns off. The filled cassette is removed and installed empty.
