Description

The invention relates to electrical engineering, in particular to the manufacture of electric capacitors of constant intensity, and can be used in the manufacture of sectional capacitors at the stage of assembly of sections into packages, as well as in all those cases when there is a need to complete several capacitors from a large group of according to set; total capacity to the required percentage deviation from the nominal; (experimental and tuning work). A device that can be used for picking capacitors is known, which includes a switch, receiving elements and logic elements. The receiving elements are connected to the distribution register via a switch and, in addition, the receiving elements are connected to; inputs of logic elements by the number of mines and accuracy classes. J However, the known device does not provide after measuring and sorting the pick of the collection. The use of manual labor, with which it is possible to do this at the present time, introduces subjective errors and is inefficient. The aim of the invention is to increase the productivity of the picking process. To do this, two memory blocks, a differential null-organ, a voltage divider, a coincidence block, a count of sections and actuators are entered into the device, with the diagonal of the bridge supply through the serially connected switch, the first memory block and the voltage divider connected to one the input of the differential zero-organ, the measuring diagonals of the bridges are connected via a serially connected switch and the second memory block are connected to another input of the differential zero-organ, the output of which is connected to the serial About the connected counter of the number of sections and actuators having a mechanical connection with the contact clips of the sections, and with the input of the unit owl

Aadeni, the other input of which is connected to the output of the distributor, and the output to the voltage divider.

When 1.: the errors of the proposed device, it is possible to select and assemble from a large group of sections smaller groups that have a given total capacity, percentage deviation and the number of sections in one capacitor,

Equally, this applies to the acquisition of finished capacitors into groups in accordance with the specified criteria in experimental and tuning works.

The drawing shows a Cr-rukurna electrical circuit device.

A device for assembling electric capacitors by capacitance contains measuring bridges 1-1, 1-2, 1-3, ..., on the shoulders of which, sections of measured capacitors to be assembled are connected through interlocked outputs.

By changing the design of the conclusions, you can i. ensure the installation of takhse and finished capacitors. The number of sections of the measuring bridge 1 is equal to the number of sections (capacitors) to be assembled, and is established experimentally, based on the condition of the presence of sections having different tolerances. Consequently, the more the original group of sections (capacitors), the better the conditions of choice will be provided.

The diagonal of the aapitki of all measuring bridges 1 is connected to the multiphase generator 2. Vveshk; The phase shift of the voltages supplying the bridges ensures a minimum of Wpg. picking.

The measuring diagrams of bridges 1 through KoMNjyTaTop 3 and the memory block 4, which are represented by a series of capacitors, are connected to one of the inputs of the differential zero-body 5. In addition, the capacitors of the block 4 are switched by a number of keys 6 on grounded bus. The shoulders are designed for comparison, in all bridges, via a series of keys 7, are connected to capacitors of the second memory block 8. The output is last through voltage divider 9 connected to the second input of the Hyjrb organ 5.

The divider 9 has an adjustable input, which is connected to the coincidence element 10, and its two outputs are connected to the input of the nullorgan 5 and the distributor 11, generating command and synchronizing pulses for all device elements (switches, coincidence element, etc.).

i The power to the distributor 11 is supplied from a multi-phase generator 2, common to the power of the measuring circuits.

The device also has a control circuit 5. For this purpose, the null-organ 5 is connected in series with the counter 12, the number of sections and the actuating elements 13, which are a set of electromechanical elements and are located at the clamping terminals, in which sections or capacitors are located in the operating state, which are enclosed in a set box.

elements 13 establish sections, of which the further smaller groups, necessary for the manufacture of capacitors, are further completed.

Before the start of measurement, selection and picking, a reference voltage is formed that corresponds to the maximum

The reference direction is formed by changing the parameters of the controlled active divider 9. All bridges are constantly

The serial switching of a key with 3 diagonals of bridges 1 in a certain sequence, measures the capacitances of the sections. In the same aftermath (5

The sequence of the section selects / t so; with the help of zero.-orgA11a 5, comparing a su.mmarc example, which is proportional to the capacity of the section found and selected, with a reference voltage.

Simultaneously with the selection of a given value of the total capacitance, the number of sections constituting the kit for one capacitor is recorded using a reversible counter 12.

As a result, a command signal is generated that is applied to an executive electromechanical antifilter f 13. The latter are discharged selected (completed) sections into a receiving hopper. During the picking process, a case is possible in which in the initial large picking group there are no secures with a maximum percent deviation of capacity. In this case, the divider 9 is automatically adjusted in the direction of changing the reference voltage corresponding to the smaller deviation of the capacitance from the nominal value. In this case, the picking is carried out taking into account the smaller deviation of the capacitance from the nokshnal. redmet of the invention; A device for assembling electrical capacitors in capacitance, containing a generator connected to a diagonal of the power supply of measuring bridges, a number (Which is equal to the number of capacitors in the initial group for picking, a distribution unit, switches, receiving elements, characterized in that, in order to improve the process performance set, two memory blocks, a differential null-organ, a voltage divider, a coincidence block, a section number counter and actuators, and The bridge power supply via a serially connected switch, the first memory block and a voltage divider are connected to one differential zero-organ input, the bridge measuring diagonals are connected via a serially connected switchboard and the second memory block to another differential zero-organ input, the output of which is connected to serially connected to the counter of the number of sections and executive elements having a mechanical connection with the contact clips of the sections, and with the output of the coincidence unit, another: 1 | the input of which is connected to the output of the distributor, and the output with the voltage divider.
