Description

The invention relates to electrical engineering, in particular to the manufacture of electromagnetic hermetic relays, and can be applied in the radio, instrument-making and electronics industries.

The purpose of the invention is to expand technological capabilities and increase productivity.

FIG. 1 shows the layout of the mechanisms of the device; in fig. 2 - kinematic scheme of the coordinate mechanism; in fig. 3 - the trajectory of the movement to-Assets; in fig. 4 shows section A-A in FIG. 2

The device for assembling a sealed relay comprises a housing 1 (FIG. 1) a multi-position rotary table 2 with fixtures 3 fixed thereto for fixing assemblies (for example, magnetic 4 and contact 5 systems), welding heads 6, a mechanism 7 for unloading finished products and drive (not shown).

The mechanism 7 for unloading finished products consists of a manipulator 8 with an electromechanical gripper 9 and a coordinate mechanism 10.

Coordinate mechanism 10 (Fig. 2) contains a plate 11, on which the gear motor 12, the lower fixed slide 13, the beam 14 and the comb 15, the carriage 16, the upper movable slide 17, the gear 18, the upper and lower cranks 19, one-turn the clutch 20, the upper and lower rods 21 of the sled control and the knife 22.

The lower slide 13 comprises a guide 23, along which the carriage 16 can move, carrying the upper slide 17, which is turned at a right angle to the lower slide 13. In addition, the upper 24 and lower 25 fasteners are fixed on the carriage 16.

In beam 14, the position where the control force P is applied, the blade 22 pivotally fixed parallel to the bottom skid 13 over the entire stroke of the carriage 16. The knife 22 is constantly pressed by the spring 26 to the lower stem 21. The knife 22 has adjustable stops 27, which are installed at the points of transition from row to row (points 1 and 10, Fig. 3).

Both the lower slide 13 and the upper slide 17 comprise a slider 28 with a spring loaded roller 29 and a fork 30, which is a reversible freewheel. In addition, the upper rails 17 contain a guide 31, made in the form of a comb, similarly to the comb 15, on which brackets 32 for mounting the cassettes 33 are placed, in which slots the finished products (relay) are installed.

The guides 23 and 31 are fitted with adjustable stops 34, which serve to reverse the stroke of the carriage 16 and the slide 17. Motor-reducer 12 through gear 18, consisting of a gear wheel 5

35, a cylindrical 36, a central bevel 37 and an upper and lower 38 bevel wheels, is associated with cranks 19. Cranks 19, having a stepless adjustment of eccentricity e through a one-way clutch 20 (FIGS. 2 and 4), formed by a gear wheel 38 and the leash 39, with the ratchet 40 and the dog 41 attached to them, is associated with the rods 21.

The ratchet 40 is rigidly fixed on the hub 0 of the gear wheel 38, and the leash 39 with the dog 41 mounted on it is on the axis of the crank 19. Both the lower and upper rods 21 of the slider controls have rigid stops 42 which engage with the one-turn clutch 20, and spring 43 compression.

A device for assembling a sealed relay operates as follows.

The nodes (for example, magnetic 4 and contact 5 systems) to be welded are manually assembled and placed in the fixture 3, located at the I loading position (Fig. 1), then the drive (not shown) is turned on. The fixation of the relays installed in the fixture 3 and the rotation of the turntable 2 on one step is automatically carried out. At position I, the next relay is loaded and fixed, and at other positions the following operations are carried out: II - control; III and IV - welding (there is a welding system of magnetic 4 and contact 5 systems, successively on two points, as shown in Fig. 1); V - unload the welded relay and install it in the cassette; VI - reserve.

The manipulator 8, which is included in the mechanism 7 for unloading finished products, with an electromechanical gripper 9 takes the relay after welding from the device 3, transfers it to a single point above the coordinate mechanism 10, lowers it and places the relay in the slot of the cassette. Each cassette slot is fed to the loading position by the coordinate mechanism 10. Since the last SRI is connected via an electrical connector to the electrical circuit of the proposed device, the gearmotor 12 is turned on simultaneously with the main drive being turned on. From gearmotor 12 (Fig. 2), the gear shaft 35, the cylindrical wheel 36 and the central bevel wheel 37 rotate to the upper and lower gear wheels 38, which rotate freely on the axles of the cranks 19. A cassette 33 is mounted on the brackets 32 of the upper slide 17 so that it is the first or last cell at the point of arrival of the gripper 9 of the manipulator 8.

After the manipulator 8, by means of the gripper 9, transferred and installed the first relay to the first slot of the cartridge 33, the actuator 5 of the proposed device is supplied with a control force P to the beam 14 pivotally connected to the knife 22. Since the knife 22 is constantly pressed spring 26 to the bottom of the rod 21,

This movement is transmitted to the lower crank 19, through a one-turn clutch 20. When the knife 22 is pressed on the rod 21, it moves to the left and retracts the stop 42, which is in the path of the leash 39 (Fig. 4), which engages with the spring 44 ratchet 40, driving the crank 19. At the same time, the rod 21 by the abutment 45 (Fig. 2) presses the roller 25, removing it from the slot of the comb 15. The carriage 16 is released.

Having made one full turn, crank 19 first moves slider 23 to a distance equal to twice the eccentricity and step of loading the relay, and then returns to its original position. When moving in the forward direction, the spring loaded roller 29 is wedged between the inclined plane of the slide 28 and the guide 23 or 31 of the slide 13 or 17. The return stroke of the slide 28 is idle. The carriage 16 is moved one step. The rod 21 returns to its initial position under the action of the spring 43. The leash 39 slides against a hard stop 42, releasing the ratchet 40. At the same time, the stop 45 LETS FIXA2, the stop 45 releases the latch 25 and it engages with the next groove of the comb 15. The carriage 16 makes one step along the X axis, feeding the next slot of the cartridge for loading, and so nine steps to point a (fig. 3). At point a, at the moment the retainer 25 comes into the groove of the comb 15, it is pressed through the stop 27 by the fork 46 of the knife 22 to the upper rod 21. The one-way crank 19 is activated into the work of the one-way clutch 20. Similarly to the carriage 16, the slider 28 moves one step the upper slide 17, i.e., to point b along the Y axis. At the same time, the slider 28 located on the lower slide 13 pushes the fork 30 against the support 34 and switches the roller 29 to work in the opposite direction, i.e. the carriage stroke 16 is reversed The knife 22 under the action, the spring 26 lowers-s on the bottom brush 21 and the subsequent nine inclusions cause the carriage 16 to move along the X axis down to the point c. At point c, as at point a, the knife 22 is pressed against the upper stem 21 and the upper slide moves one turn along the Y axis to the point e. The carriage 16 also reverses the stroke and moves again along the X axis to the e and t points. e. through the points /, / and / to the point

k. After stopping at the point k, the cassette 33 is replaced, the t-plug 46 is pulled out from under the stop 27, and further movement occurs in the opposite direction to the point o. The cassettes 33 are also changed here. The positioning accuracy is ensured by the choice of the gap between the groove of the comb 15 or 31 and the prism of the latch 25 or 24 under the action of the return spring 47.

Thus, in comparison with the known, the proposed device allows to automate the process of unloading and installing a relay after welding two systems into a cassette, i.e., to expand the technological capabilities of the device; unload and install the finished relays into the cassette without exposing them to mechanical effects, thus avoiding the rejection of the finished relays, which when discharged into bulk in containers make up about 2% of the total output, and also increase the device performance by eliminating manual installation of the relay in the cassette .
