The invention relates to the field of welding and can be used in the manufacture of radio components.

The purpose of the invention is to increase the productivity and expand the technological capabilities by providing the welding of soft, fine leads.

On fmg.1 shows a device for welding anodes of capacitors to the rail, general view; in fig. 2 - spring loaded.

The device contains guides 1, a pusher 2 of longitudinal movement for sequential feeding of cassettes 3 with anodes 4 to movable platforms b and 6 at the position of trimming the leads 7 and at the position of welding them with the rail 8 and further at the unloading position. Separate unloading of the rail with the welded anodes and the released cassette is carried out with the help of the pusher 9, which interacts with the inlet bevels, the receiving bar 10 of the accumulator (not shown) for the strips with the anodes. Freed from the anodes, the cassette under the force of gravity falls on a pallet (not shown).

The device cut-off unit includes a movable platform 5 pressed to the guides 1, spring-loaded with a spring 11, a clamp of conclusions in the form of a converging comb 12 and a clamp 13, cutting edges 14 with bevels 15 on the side of the anodes being cut for notching the leads 7 and made integral with recess the edges at a distance of 2 mm, tear-off contacts in the form of a plug 20 and a clamp 21 mounted on 2 contact groups 18, 19 clamp all the terminals A 4 at the same time, and platform 6 departs, leaving A4 on weight. The rail 8 and the welding pulse are applied. After welding, contact groups 18, 19 are consumed, A 4 with a welded rail falls into a short-circuit, which is unloaded. In the unloading position, the pusher 9 puts on the rail with A4 on the inbound bevels of the receiving bar 10 Drive, carried out a separate unloading of the rail with A4 and short-circuit. 2 hp f-ly, 2 ill.

plate 16 and a cushioning stop 17 made of sponge rubber; compressed air is supplied there for blowing out the lead pieces (not shown).

The welding unit includes a movable platform 6 pressed to the guides, two contact groups 18 and 19 with contacts in the form of a fork 20 and in the form of a hinged and spring-loaded clamp 21, respectively, a forced movable carriage 22 with a hard stop, equipped with fixed stops 23 and double spring-loaded contacts 24, forming a socket for the rail 8. The welding pulse to contacts 20-21 and 24 is supplied from a capacitor bank (not shown). To prevent bending of the leads during fixation, a predetermined orientation of the position of the cassettes is provided by means of holes 25 and conical catchers 26 applied to them. The pneumatic system is used as a drive.

The device works as follows.

At the loading position set the cassette 3 with the anodes 4, press the button -.

30 ku start, and the pusher 2 of longitudinal movement transmits the cassette 3 firmly pressed to the guides 1 platform 5 at the position of the output segments. To prevent the bends of the leads from the teeth of the comb 12, a conical catcher 26 enters the cassette hole 25 and orients it, i.e.

anodes in it, relative to the grooves of the comb. Then the safety device 26 returns to its original position, weakens the pneumatic clamp on the platform 5. All the leads in the cassette are fixed with the help of the comb 12 and the clamp 13 entering in it, converging to the pin location line. The cutting edges 14 are closed, the pins 7 are incised, the angle of the cutting edges on the side of the BOB is 55-65 °. In this case, the downward components of the cutting forces, acting on the leads, do not bend them, but transfer the force through them to the spring 11, precipitating the movable platform 5. The outer plate 16 mounted at the same time as the cutting edges and the cushion stop 17 capture the lead at a distance of 2 mm from the notch, and with further deepening of the plate 16 into the body of the abutment, the notched part of the lead is torn off. By withdrawing the cutting edges 14 and the connector 16 of the plate 16 and the stop 17, compressed air is supplied and blows off the cuttings into a container (not shown). The cassette platform 5 is pressed against the guides 1.

The cassette is reloaded and the rail 8 is loaded into the slot of the carriage 22. The pusher 2 moves one cassette to the segment position on platform 5, and the cassette with cut leads to the welding position on platform 6. To prevent the cassette pins from bending on the rigidly pressed platforms 5 and 6, they are oriented by means of conical catchers 26 and holes in the cassettes 25. Catchers 26 are raised, repetition - there is a cycle to trim. At the welding position, contact groups 18 and 19 converge, bringing together contacts 20 and 21. The cut off leads of the anodes 4 are clamped by contacts, the platform 6 with the cassette moves downwards. Anodes remain suspended. Extendable stops 23. The pneumatic cylinder (not shown) moves the carriage 22 downwards, a double pulse is applied to the double closed contacts 20 and 21 of the terminals and the contacts 24 of the rail, and an arc is ignited between the terminals of the anodes and the rail. Moreover, the ignition starts from the highest burr of the broken output from all the leads that have an uneven breakage at the pointed ends, which significantly reduces the ignition voltage (up to 20%).

The rake collides with the leads of the anodes. Dual contacts, providing

concentrated heat release and uniform heating also reduce energy costs. Plastic deformation of the metal at separation and subsequent

uniform warming up ensures, when reflowing and colliding, a mechanically and electrically reliable connection of the leads to the rail, eliminating the fragility of the joint. Possible impact

on the quality of welding, unevenness of the level of tearing neutralizes the design of the contacts 21 (Fig. 2), which, due to the springback and hinge fastening, allow clamped on the weight

between the contacts 20 and 21 of the terminals, if necessary, individually sit down in the direction of impact, excluding to the same the deformation of the output upon impact. After an intermediate height

the welding and cooling time of the platform 6 with the cassette and the carriage 22 is returned to its original position, at the same time the contact groups 18 and 19 are consumed, and the anodes with the welded rail again

provided in the slots of the cassette, the withdrawable stops emerge, forming a socket with receptacle contacts 24 for receiving the next rail 8.

Again, the cassette with anodes arrives at the loading position, and the longitudinal movement pusher 2 again moves it to the cutting position, the cassette with cut leads to the position

welding, and a cassette with anodes welded to the rail - to the unloading position. The cycle is repeated at the cutting and welding positions. On the unloading position to the cassette with the rail, on one side, the pusher 9 approaches, on the other, the strips with bevels 10 of storage (not shown). The entry bevels of the strips 10 enter between the cassette and the rail with anodes. Upon further movement and pusher the rail is put on the slats, separated from the cassette that falls on the pallet (not shown).

The box office with anodes is loaded again, the rail is loaded, and all the mechanisms of the device are reset, the cycle is repeated.
