Description

one

The invention relates to the design of equipment for the production of radio components.

Contact devices are known, for example, to connect radio components with unidirectional leads to a measuring unit, with a transporting rotor with contact clamps, each of which is made in the form of two movable levers placed in a housing, with one arm of the first lever provided with a dielectric partition, and the other is connected gears with a second movable lever, and the drive mechanism.

The purpose of the invention is to increase the reliability of contacting in the proposed device, each contact clip is provided with a rod placed in the housing, in the middle part of which a cogged rail interacting with the first lever is fixed on its surface and the doggie is rigidly fixed named spring-loaded elements placed on the second lever on both sides of the dielectric enclosure of the first lever, and fixed on the second lever by a roller interacting with a doggie rod, and the drive mechanism is equipped with a pusher that moves the second lever.

FIG. 1 shows the kinematic diagram of the device; in fig. 2 - contact clip, side view and top; in fig. 3 - section along the AL; in fig. 4 - section along BB.

The transporting rotor 1 with a vertical axis of rotation is connected by gears 2 and 3 with a drive 4. With 5MB sprockets and a chain 7, a pusher 8 is connected to a double-arm lever, at one end of which a flat spring 9 is fixed, and the other arm is connected via rod 10 eccentric 11, for crushing: on the shaft 12.

On the rotor / placed with a certain step contact mechanisms 13.

Copier 14 is installed in the loading zone above the rotor. Electromagnets 15 with levers 16 are placed in the discharge zone.

On housing 17 of each contact mechanism 13, screws 18 are fastened with a block 19 with contacts 20.

The findings of the radio components 21 are clamped to the contacts 20 by metal plates 22 of the levers 23 and 24 using the springs 25 and 26 located in the slots of these levers mounted on the unary shaft 27, the lever 28 placed in the housing 17 on the fixed axis 29.

The gear 28 is rigidly connected to the lever

30 being in engagement with the gear

In the housing 17 on the axis 32. On the free shoulder 31, a dielectric partition 33 placed in the slot of the pad 19 is fixed, separating the contacts 20 of the pad 19 and the levers 23 and 24.

The lever 28 is pressed in the upper position (clockwise) by a torsion spring 34, one end of which is tucked into the groove of the axis 29.

The spring 34 is prevented from axial displacement by the split face 35. In addition to the springs 25 and 26, the levers 23 and 24 in the upper position of the lever 28 are clamped by flat springs 36 attached to the lever 28 by screws 37. On the lever 28, besides, there is a limiter 38.

In the housing 17 is located the slider 39, on the axis 40 of which is located the roller 41, partially placed in the slots of the housing. In the middle part of the blade, the rail 42 is axially secured with the possibility of displacement by the gap size e.

The rod 39. Supports 1s (In the upper position by the spring of compression 43, the force, which is not; you can adjust the displacement. Of the finger 44 fixed to the bracket not by 45 by a nut 46. The crot. Pin is rigidly fixed on the body.

At the lower end of the slider, the dog 47 is rigidly fixed, resting in the upper position of the lever 28 on the roller 48 mounted on the axis 49 of the lever 28.

The device works as follows.

The rotor / through gears 2 and 5 receives an intermittent rotation from the actuator 4. Through the sprockets 5 and b and the chain 7, the rotation from the actuator is transmitted to the shaft 12 and the eccentric 11, which through the connecting rod 10 sets the pusher lever 8 in rocking motion.

When the rotor rotates. The contacting mechanism 13 is brought in the loading area under the copnr 14. The roller 4.1 of the choke 39 rolls onto the copier, lowers the brush, and the gap e is selected at the first moment, and only after the dog 47 leaves the roller 48 of the lever 28, The rail 42 rotates the lever 31 with the dielectric septum 33 clockwise, and the lever 28 with the bristles 30 rotates counterclockwise, overcoming the force of the spring 34, at a certain angle to ensure the arms 23 and 24 move away from the flat springs 36.

In this position, the levers 23 and 24 with their overlays 22 are pressed against the contacts 20 of the pads 19 only by springs 25 and 26, than

provides ease of loading mechanism

contacting.

After further rotation of the rotor / contact mechanism 13 comes down from the copier 14 and goes under the pusher 8, which at the time of the firm prince 9 lifts the lever 28 of the contact mechanism. The rod, 39 under the influence of the spring 43 moves to the upper position, and the dog 47 drops under the

roller 48, stopper lever 28 in the upper polishing. However, the findings of the radio component 21 are pressed against the contacts 20 by the force of the springs 25, 26. In this position, the parts are brought to the measuring position.

At the reset position, the electromagnet 15, at the command of the measuring units, rotates the lever 16. The roller 41 raids this lever and lowers the brush 39. The levers 28 and 31 open at an angle that ensures retraction

the overlays 21 of the levers 23 and 24 from the contacts 20 of the pads 19. The levers 23 and 24 are raised under the action of the springs 25 to the extreme position and held by the stop 38.

The dielectric partition 33, which separates the outputs of the radio component, is removed, and the part is completely released. Under the influence of gravity she falls into the receiving bunker.
