Description

The invention relates to the field of control of radio components by electrical parameters, in particular, to devices for connecting flat radio components, such as diode crystals, to a measuring unit. The purpose of the invention is to increase the reliability of operation due to yi iehb-likelihood of damage to radio components in the process of connecting them to the measuring unit, as well as eliminating sticking of radio components to the contacts of the contact heads.

Fig. 1 shows a setup for grading crystals on a fit. device for connecting radio components to the measuring unit, section, in fig. 3 shows a contact head, a section in FIG. 4 is a section A-A in FIG. 3

A device for connecting flat radio components to the measuring unit is included in the installation for screening crystals by electrical parameters, which contains installed on the base 1, a control unit and a measuring unit housed in the housing 2, mechanisms 3 loading crystals from the accumulator cassette 4 to the transporting rotor 5 connecting flat radio components 6, for example crystals, to a measuring unit, mechanisms 7 for unloading broken crystals from a transport rotor 5 into receiving cassettes 8, the number of which corresponds to the number of crystal display groups j and the mechanism 9 for unloading rejected crystals into the receiving cassette 10 and the control panel 11 of the control.

The device for connecting flat radio components to the measuring unit contains a transporting rotor 5 and contact goggles, kinematically connected by means of a shaft 13 placed in a housing 12 with an installation drive mechanism. On the shaft 13 there is a pair of cams 14, which, with the help of two spring-loaded levers 15, provide for the reciprocating movement of the holders 16 with the contact heads 17 and 18 coaxially located one with respect to another.

The cams 14 are fixed on the shaft 13 with the aid of a tightening bolt 19,

which makes it possible to rotate the cams 14 relative to the shaft 13, thereby obtaining the necessary phase shift of the contact heads 17 and 18 relative to each other in accordance with the unit operation pattern.

The contact heads 17 and 18 are fixed in the holders 16 by means of tightening bolts 20, which provides vertical movement of the contact heads 17 in a vertical plane relative to the socket 21 to accommodate the radio components of the transporting rotor 5,

One of the contact heads (contact head 17) is installed above the transporting rotor 5, made with a spring-loaded contact 22 and provided with additional spring-loaded contacts 23 placed around a circle concentric to the axis of the main spring-loaded contact 22. The main spring-loaded contact 22 is measuring, and additional spring-loaded contacts 23 - current,

The basis of the spring-loaded contact 22 can be made shorter or longer than the additional contacts 23 by the magnitude lb, which ensures the initial and subsequent loading of additional biased contacts 23 to the crystal 24 located in the slot 21 of the transporting rotor 5,

The transporting rotor 5 is provided with supporting sleeves 25 of electrically conductive material, movably mounted in its sockets 21, made in the form of cups 26 of isoshing material and fixedly mounted on the transporting rotor 5.

Another contact head 18 is installed under the transport rotor and is designed as a housing.

27,

at the top of which is fixed

Lek hard current contact 28,

In the center of the current contact 28B of the insulating sleeves 29 there is a measuring spring-loaded contact 30.,

Support sleeves 25 of the transporting rotor 5 are installed with the possibility of cooperating with the hard current contact 28 of the contact head 18.

To prevent crystals from sticking to the contacts of the contact head 17 mounted above the transporting rotor 5, additional spring-loaded contacts 23 are made of different lengths.

The device works as follows.

A cumulative cassette 4 with crystals to be screened by electrical parameters, empty receiving cassettes 8 for the crystals of the corresponding reflecting groups, and also a receiving cassette 10 for crystals not included in one of the three previous irpynn casings are installed on the installation.

i Turn on the drive of the installation, as a result of which the mechanisms of 3 loading of crystals begin to operate, providing a single supply of crystals to the discretely rotating transporting rotor 5.

When moving the crystal 24 to the measurement position in the slots 21 of the transporting rotor 5, the following actions take place during the whole process.

The drive shaft 13, when rotated from the drive of the machine, rotates the cams 14, which, in order to ensure reliable contact, provide the initial vertical movement of the upper contact body.

17, which with its additional spring-loaded contacts 23 presses the crystal 24 against the surface of the support sleeve 25, after

5, with some delay by the bottom hard contact 28, the support sleeve 25 moves with the crystal 24 upwards and at this moment reliable contact occurs.

10 Then, the main spring-loaded contact 22 of the contact head 17 and the measuring spring-loaded contact 30 of the contact head 18 are closed and the parameters of the crystal 24 are measured. With the subsequent rotation of the shaft 13, the contacts open. After fully opening, the transporting rotor 5 begins to move 20 seconds, moving the modified crystal from the measurement position to the zone of action of the mechanisms 7 unloading deflected crystals from the transporting rotor 5 to receiving cassettes 25 or 8 to the position of the unloading crystals 9 to the position measuring transporting the rotor 5 moves the new crystal 24 and the cycle resumes.

thirty

Thus, the radio components are connected to the measuring unit and the crystals are distributed on

groups.
