The invention relates to resistance welding and can be used in devices for aligning the clamps with respect to the rim of the microcircuit case and fixing them in the position for welding directly during the movement on the conveyor.

The aim of the invention is to increase productivity.

Figure 1 shows the sealing mechanism of semiconductor devices; figure 2 - section aa on fig1; on fig.Z - section bb on fig1} on figure 4 - welding frames, section on figure 5 - a type g in figure 1. .

The semiautomatic device contains a movable bracket 1 located in the body of the guides 2 on which a spring-loaded lever 3 is fixed, which by its grasp engages with the axes of 4 links of the conveyor chain 5 under the action of the spring 6 and moves the movable bracket 1 to the adjustable stop 7. The return movement of the movable bracket 1 is provided by a return spring 8 and is limited to the cushion 9. Manually, the bodies 10 and the chips 11 of the microcircuits are installed manually in the links of the chain 5 of the conveyor.

In the housing of the movable bracket 1 there is a cavity 12 and an opening 13 in the walls 14, in which a spring-loaded piece 15 is installed, on which the copier 16 located in the cavity 12 is fixed, the carriage installed in the same cavity moves through the roller 17 by moving the copier 16 18 horizontal movement. On the protruding beyond the cavity 12 -. part of the carriage 18 horizontal displacement installed carriage 19 vertical movement, on the bottom

the cover 11 on the rim has an offset towards the stop-die 20, then when the latter is moved, the rim of the body 10 and the cap 11 will be aligned in the direction relative to the conveyor. 5 il.

the end of which is fixed spring-loaded support biller 20. Also on the horizontal movement carriage 18, a retainer 21 is installed, consisting of a spring-loaded piston 22 with a protruding inclined part 23 and a spring-loaded stopper 24, a rocker arm 25, one end of which through a spring-loaded rod 15 ending with a roller 26, associated with a fixed cam 27 mounted on the body of the guides 2 of the movable arm 1, and the second end interacts with the roller 28 of the vertical carriage and with a spring-loaded stopper 24 of the clamp 21. On p In the case of a semiautomatic device, a component fixation unit 29 is rigidly fixed to the welding position, including two spring-loaded prisms 30 mounted above the conveyor, directly in front of the welding rollers 31 and made with bevels, forming an alignment lead-in groove 32 for the assembled body of the chip pressed against this section of the conveyor with a spring-loaded stop -battle 20 before welding.

The device works as follows.

The spring-loaded lever 31 engages in engagement with the axis 4 of the chain link 5 of the moving conveyor and drives the MOVING bracket 1.

When moving the movable bracket 1, the spring-loaded rod 15 with its roller 26 hits the inclined surface of the copier 27 and moves upwards. At the same time, the copier 16, fixed on the spring-loaded rod 15, through the roller 17 moves the carriage .18 of horizontal movement to the right and lifts one end of the rocker arm 25 relative to its axis fixed on the carriage 18 of horizontal movement, while the other end of the rocker arm 25 interacts with the latch 21, and its (rocker) curved part interacting with the carriage roller 26 of the vertical movement is lowered. Also, the vertical movement carriage 19 is lowered together with the stop-driver 20 mounted on its lower end until it stops 33 placed on the horizontal movement carriage 18.

The vertical movement of the carriage 19, together with the spring-loaded ram support 20 to the stop 33, takes place in a small area compared with the total length of the ramp surface of the copier 27. The push-pull 20 takes up such a position that its lower part is located below the level of the grinder 11, but slightly above the upper surface of the housing 10. With further movement of the rod 15 along the inclined surface of the copier 27, the stop-plunger 20 performs only a horizontal re- mainment, and by the time of the roller exit, the distance to the rim of the housing 10.26 of the spring-loaded stem 15 on the lower slope

At this moment, the rod 15 from the surface moves to the horizontal section of the copier 27. If during the installation of the bolt 11 on the rim of the housing 10, the bolt was shifted in the opposite direction to the conveyor, i.e. in the direction of the stop-dopepatel 20, then when you move the last

The scientific research institute has a horizontal section of copier 27. The end of the rocker arm 25 retracts the spring-loaded stop 24, and the piston 22 moves to its extreme right position under the action of its spring. At the same time, the curvilinear surface of the rocker arm 25- holds the entire carriage 19 vertical for roller 28

the rim of the body is moved to the up position.

CA 10 and caps 11 in the direction longitudinal with respect to the conveyor movement. This combination occurs before the orienting lead-in groove of 32 spring-loaded prisms 30,

If at installation of the bolt 11 on the rim of the housing 10 there was a lateral displacement of the cover or towards the side. conveyor belt from the spring-loaded stop 20, the latter, having reached the rim of the housing 10, subsequently makes a movement synchronous with it, equal to the movement of the

With further reciprocating movement, the movable bracket 1 abuts against the cushion 9 and stops, and the qi is repeated.
