(54) DEVICE FOR THE SELECTION OF RADIO ELEMENTS IN THE GIVEN ORDER

I

The invention relates to the technology of radio equipment and can be used in the radio, electronic and communications industry in the preparation of radio components for mounting on printed circuit boards.

A device for selecting radio elements in a predetermined order is known, including feeders located along a pressing conveyor with an adhesive mechanism, each of which has an orienting and feeding radio elements in the package of the device 1.

The disadvantage of the device is that it works only with radio elements glued into the tape, i.e. with radio elements having long leads. The industry produces radioelements with such conclusions in small quantities, therefore, such an installation has limited application.

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved by the fact that each feeding device is made in the form of a pusher lift and a conveyor having mechanisms for opening and guiding packages and cradles for radio elements.

In addition, each package of radio elements is made in the form of a technological cassette with a locking plate, the directional mechanism is made in the form of two rows of drive rollers placed along the conveyor belt, and the opening mechanism is made in the form of a stopper arranged to interact with the locking plate.

FIG. 1 shows a device for

10 sets of radio elements in a given order; in fig. 2 - radio elements glued to the tape in a given order; in fig. 3 - reloader, general view.

Claims (2)

A device for collecting radio elements 5 tov in a given order includes a pressing conveyor 1, an adhesive mechanism 2, feeders, each made in the form of an orienting and feeding radio element in the packaging of devices. In this case, the radioelements in the packaging device are made in the form of a lift 3 for packages in the form of process cassettes 4 with a locking plate (not shown), having a pusher 5 and a conveyor 6. The conveyor 6 has a mechanism 4 for directing the packages in the form of two rows of drive rollers 7, a mechanism 8 opens in the form of a stop for interacting with the latch of technological cassettes and cradle for radio components in the form of brackets 9. The orienting device of each feeder is made in the form of guides 10 and a screw orientator 11, which are The radio elements being moved around the tray are rotated by 90 °. The glueing mechanism 2 has two gears 12 fixed on one shaft 13. Each wheel 12 has two rows of teeth and a groove between them (not shown) into which the lower belt 14 is fed. The upper belt 15 is pressed by pressure rollers 16. Blocks 17 with cassettes 4 are placed on the lift 3 with the possibility of lifting under the action of periodically turning crosses 18. The device operates as follows. The radio element cartridges 4 are placed in blocks 17, which are loaded into device cells. Each block 17 contains radio elements of the same type. The number of blocks 17 is determined by the number of types of radio elements to be sorted. From block 17, the cassette 4 is pushed out by the pusher 5 and falls between two rows of rollers 7 above the conveyor 6. The cassette 4 moves up to the stop 8. After the interaction of the stop 8 with the locking plate of the cassette 4, the latter opens and the radio elements are poured onto the conveyor belt 6 and fall into the brackets 9. With the conveyor belt 6, the radio elements are fed into the guides. 10. Moving along the screw orientator 11, the radio elements are turned 90 ° and move from the horizontal position (in the cassette) to the vertical position. Then the radio elements are fed by operation to press transport conveyor 1 in the sequence specified by the program. Conveyor 1 feeds them to the gluing mechanism. The radio elements fall between two rows of teeth of the gear wheels 12 and are laid over the tape 14. On top, the leads of the radio elements are covered with tape 15 and rolled by rollers 16, which ensures the bonding of radio elements between two parallel strips. Thus, the device provides a selection of radio elements of any length of leads in a predetermined order before installing them on the printed circuit boards. Technological cassettes suitable for radio elements with any terminal length are used as device feeders. In these cassettes, radioelements pass through the previous technological operations — tinning, flotation, etc., and directly into them go to the picker. This makes it possible to eliminate the operation of transferring radio elements from the cassette to the tape before the operation of picking and cutting the radio elements from the tape during the process of picking. Such improvements can improve the performance of the entire process of preparing radio elements for installation on printed circuit boards by a factor of 2. In addition, the proposed device provides automation of the process of plywood of radio elements not only with long leads, but also with short ones. Claim 1. Device for selection of radio elements in a given order, including feeders located along the receiving conveyor with the glue mechanism, each of which has an orienting and feeding device, characterized in that, in order to enhance technological capabilities, each feeding device is made in the form of an elevator with a pusher and a conveyor having a stop and a guiding mechanism. 2. A device according to claim 1, characterized in that the guiding mechanism is made in the form of two rows of drive rollers placed along the conveyor belt.
