Description

one

The invention is intended for use in the electronics industry, for example, when bulk loading cassettes with leads in the manufacture of metal-glass semiconductor enclosures.

Devices for loading terminals into cassettes are known, consisting of a magazine, a stencil, a cao carrier, a cassette lifting mechanism for loading, a cassette fixing unit with a stencil, and a vibrator. In these devices, the store cells are filled with leads at the beginning, and they are manually filled during work. Often this process is separated into a separate operation for laying the leads into the store, for which a whole range of auxiliary devices is used with a large amount of manual labor.

The purpose of the invention is to increase the productivity of bulk loading of leads into the cassettes.

To do this, in the proposed device, the vibrato bin issues parts to the rocking lotOK — a slide above the reciprocating rectilinear motion of the linear vibratory track with longitudinal slots for uniform screening of leads above the surface of the magazine mounted on the stationary vibrating channel.

FIG. 1 shows a general view of the proposed device; in fig. 2 - the same plan view.

The terminal loading device includes a vibrating hopper 1, a swinging tray-slime 2 and a straight vibrating channel 3 with longitudinal grooves, reciprocating to sift the leads to the surface and then into the cells of the store 4 with a stencil 5.

Supply, orientation and accumulation of conclusions in the store and loading them through the holes of the stencil 5 in the cassette 6 is carried out under the action of their own weight and vibrations, for which the store is installed on a stationary vibrating tray 7.

The cassette carrier 8 serves to feed the cassettes 6 (for example, two pieces at a time) to the zone of action of the cassette lifting mechanism 9, which feeds them before fixing with the stencil 5. All the main mechanisms of the device are placed on the table 10.

The receiving box 11 and the tray 12 (see FIG. 2) serve to collect the leads that did not fall into the store cells during the sieving process.

The control of the mechanism for loading the terminals is carried out by a system of 13 cams located on the camshaft and electro-automatic devices. The device works as follows. Vibrating bunker 1 on the command of the distributor shaft 13 supplies the output to the scraper tray 2, which, with a swing, distributes parts over the moving vibrating channel 3, with grooves. The latter reciprocates during vibrations, sifting the leads onto the stationary vibratory channel 7 in the area of the store. At the same time, the sowing of the 3 longitudinal wheels of the vibrating tray 3 is carried out along the O.SI of the store cells to increase the effect of directly drawing conclusions into them. Separate outputs that did not enter the store cells move further along tray 12, are dumped into the receiving box AND, and subsequently sent back to the vibrating tank 1. The use of such a screening scheme ensures high performance of the operation and a constant cleaning of the surface of the store from the conclusions, which excludes cases of long stacking thin, and therefore easily deformable leads, and their supply is carried out by a controlled flow. At the end of the raosev and the accumulation of leads in the store, the vibrails and 7 are turned off. The cassettes 6 to be loaded with leads are mounted on the cassette holder carriage 8 and the operator enters them into the area of the cassette lifting mechanism 9. After the cassettes are connected to the stencil, the stationary vibratory flow is started and the leads are loaded from the magazine through the stencil holes in the cassettes. At the same time, the leads are sifted above the magazine when the moving vibrating trajectory 3 is turned on. When the loading of the vibrating trays 3 and 7 is finished, the elevator goes up, takes the cassettes with its paws and lowers them onto the cassette carrier. This ends the automatic mode of operation. The operator then takes the cassettes out of the loading area, replaces them with new ones to be loaded, and the work cycle repeats. The subject of the invention is a terminal loading device containing a vibrating bunker, a associated tray — a slip, a linear vibrating channel, and a magazine with a vibrator, characterized in that, in order to increase productivity, the lottery cliff is designed to swing over the linear vibrating trajectory moving reciprocatingly Share the surface of the store.
