rotation through gears 13-15 and clutch 16 controlled by electromagnet 17c

In order to impart to the device an additional function of the former group of products and to ensure their group control in the transport rotor 9, parallel to its axis of rotation, the guides of the 18th straight linear motion are mounted along the generator of the cylinder. In addition, the device has additionally introduced a stepper translational drive displacement of measuring heads 19, section-) 5 placed at the positions of loading and unloading products into the transport rotor 9 "Each measuring head 19 is movably fixed in the direction of It has 18 pr - linear movements with the ability to interact with the specified drive of stepping translational movement and it has a roller 20 with the springs 21 pressed on it, the lever 22c with the roller 23 and the spring 24 of the 25 contact bus 25 and contact strips 26, as well as through electrocontact elements, are mounted on rollers 27 and 28 mounted on guides 30 18 of transport rotor 9 connected to a source of electrical (measuring or training) gear.

At one end of the rollers 27 and 28, the gear sectors 29 and 30 are interlocked. The gear sector 29 is equipped with a roller 31, which interacts during rotation of the rotor 9 with a fixedly mounted cam 40 "on the gear sectors 29 and 30, a spring 33 is fixed for opening electrocontact elements and disconnecting radio components 6 from an electrical voltage g5. The drive for step-by-step movement of measuring heads 19 is placed opposite the loading and unloading mechanisms and is designed as two running gears. screws 34 and 35 with a screw ditch

and the output of the copier rollers 37 attached to the bottom of each measuring head 19 into this groove with the possibility of their interaction with the screws and telling the heads 19 of the translational movement along the guides 18.

Supports 10 and 11 are connected by a stitch 38, on which a stop 39 is installed, interacting with the roller 23 of the lever 22. The support 11 is equipped with a contactless sensor 40 for switching on the electromagnet 17 after the arrival of the measuring head 19 to the extreme position after unloading

Mechanism 41 unloading radio components

6 is installed on the frame of the device and is connected via a lever system with the drive 120 The unloading mechanism 41 includes an electromagnet 42 controlled by a microprocessor 43 and working elements for removing parts made in the form of jaws 440

To eliminate the possible movement of the cam rollers 37 along the axis of the screws 34 and 35, while the rollers are between these screws, restrictive guides 45 and 46 are provided.

The device works as follows.

The carriage 4 with the jaws 5 for gripping the radio components 6, moving along the guides 3 of the rotary disk 2 of the loading mechanism 1, transfers the radio components 6 from the position of the segments from the technological carrier to the welding position of the mounting output. Then the roller

The 7-spring-loaded carriage 4 moves along the copier 8 to the center of the transport rotor 9 and brings the carriage 4 to the loading position of the radio components 6 into the sockets of the measuring head 19. The loading of the measuring head 19 continues as it continuously moves in the loading position o. The measuring head 19 comes to its extreme position after its unloading. At the same time, it acts on the proximity sensor 40, which turns on the electromagnet 17, which by means of the gear coupling 16 turns off the rotation odovyh screws 34 and 35 and through the toothed wheel 13 results in rotation of the rotor 9

The transport rotor 9 rotates and the roller 23 of the lever 22 comes off from the stop 39 o With this, the spring 24 is twisted

turns the roller 20 and the springs 21 presses the leads of the radio components 6 to the contact bus 25 supplying voltage from the collector through the brushes 26. The copy rollers 37 of the measuring head 19 at the loading and unloading positions, go out of the screw grooves of the driving screws 34 along guides 45 and 46 o At the same time, when the rotor 9 rotates, the roller 31 of the gear sector 29 hits the cam profile 32 and rotates the sector 29 together with the roller with electrocontact elements 27 "The sector 29 rotates the sector 30 through the gear teeth, which This turns the roller 28 along with its contacts. Thus, the outputs of the radio components (for example, anodes) are connected to the source of the measuring or test voltage, in this particular case of training voltage 0

Mostly step feed of the measuring head 19 with radio components 6 for their unloading. The sponges 44 of the unloading mechanism 41 remove the radio components 6 from the measuring head 19 and put them in a special assembly cassette, and the defective radio components 6 are dumped into the storage bin,
