Abstract

The invention relates to electrical engineering. The purpose of the invention is to increase productivity. The device for placing contacts in the connector pads contains a base 1, a multi-mode drive 2 with grooves 5 under each row, a cutter in the form of pushers 19 placed in the grooves 5, an orientation mechanism in the form of a spring-loaded slide 35 with channels 36 arranged coaxially with the grooves of the drive 5, and spring clamps 37, rammers in the form of rods 38 installed with the possibility of reciprocating movement in the channels 36 of the slide 35, and the drive. The slider 35 is installed with the possibility of reciprocating movement in the direction from the grooves of the accumulator 5 to the groove in the rails 7. The device is equipped with a blocking mechanism for the presence of a pad in the mounting position. In the absence of a block 8, the lever 17 rotates to position "a" and, interacting with the stop 18, locks the actuator of the shut-off device 19. Furthermore, if at least one contact is not installed in the socket of the block 8, for example, due to its skewing The rammers 38 stop, but the mechanism fails and the contact deformation does not occur due to the presence of a spring 28 in the drive of the orientation mechanism. The contacts remain in the channels 36, and then under the influence of the pusher 20 on the slider 35 are dumped into the tray 44.

Description

The invention relates to electrical engineering and can be used to install a group of contacts or terminals in the socket pads.

The aim of the invention is to increase productivity.

On fng.1 shows the device, the initial position; figure 2 - the working area of the device after the cutoff of a number of contacts; fig.Z - the same, after the transfer of contacts to the block; figure 4 - the same, after installing the contacts in the slots of the pads; Figure 5 - the same, in case of jamming of the contacts when installed in the pad; figure 6 - reset uninstalled contacts from the grips.

The device contains a base 1, a multi-store for contacts 2, consisting of a series of 3 guide rails, under each bar in support 4 there is a groove 5 but the width of contacts 2. On the base there is a guide 6 fixed with a longitudinal groove 7 for pads 8. A manipulator 9 is attached to the vertical plane of the base 1, consisting of a housing 10, a rod 11, a mechanism for horizontal movement of the rod, including a spring 12 pusher 13 with a roller 14, a two-arm lever 15, a carriage 16; a locking mechanism comprising a double-arm lever 17, one shoulder of which is located in the groove 7, and the other opposite to the stop 18 on the pusher 13. A cutter consisting of

p yes pushers 19 in the form of slats, located in the grooves 5 and the pusher.

5 20. A manipulator 21 is attached to the right vertical plane of the base 1, consisting of a housing 22, a rod 23 mounted in rails on the strip 24; the mechanism for vertically moving the strap 24, including columns 26 spring loaded with spring 25, connected below the bar 27, and the upper part pressed into the bracket 24 and mounted in directional bushings in housing 22, the mechanism of horizontal movement of rod 23 including spring pusher 29 spring loaded with roller 30, double-shouldered lever 31, carriage 32. To the front

0 parts of the stem 23 are attached an orientation mechanism in the form of a slide 35 mounted on columns 33 spring loaded 34 with a series of channels 36 for contacts closed under the plate5 by that spring 37. In the channels are the ends of the sprinklers in the form of rods 38. The mechanisms move from the cams 39 -41, mounted on two, synchronously rotating from

water shafts 42 and 43. On the basis of the installed tray 44 for collecting non-installed contacts.

The device works as follows.

In the initial position, the channels 36 are installed against the grooves 5, and the lower row of contacts 2 falls into the grooves along the guides 3. In the assembly position the groove 7 is fed to the assembly position, which

when moving, it acts on the lever arm 17 and rotates it, leading out the end of the second arm from under the stop 18 (Fig. 1), making it possible for the cutter to work from the mechanism for moving the rod 11, which, when the cam 39 rotates from the spring 12 through the roller 14, pusher 13, the lever 15, the carriage 16 moves the rod 11 to the right, the pushers 19 cut off a row of contacts 2 and push them into the channels 36 of the slide 35 to overcome the resistance of the flat spring 37 (figure 2).

In case of failure to deliver to the position of the assembly, the lever 17 occupies position a shown by a dash-dotted line (Fig. 1), and the second lever is under the stop 18, blocking the movement of the pusher 13 from the spring 12 down, and the contacts will not be cut off and fed into the slots of the slide block 35 , mechanisms will work in accordance with the sequence of work, but failures and failures will not occur.

After installing a row of contacts in the channels 36 of the slider 35 (in the case of feeding to the position of the pad), when the camshafts rotate, the pusher 19 is retracted to the left to the distance at which their ends remain under the contacts without allowing the bottom row of contacts in the accumulator to fall. in the grooves 5 (fig.Z). From the cam 40, the springs 25, the strips 27, the columns 26, the strips 24 and the rod 23, the columns 33 of the slider 35 are lowered and the channels 36 are installed coaxially with the sockets for the contacts in block 8 (FIG. 3). Upon further rotation of the camshafts from the spring 28, the cam 41 through the roller 30, the pusher 29, the lever 31, the carriage 32, the rod 23 moves to the left, the slider 35 rests on the block 8 and stops, and the dosimeters 38 continue to move, pushing out of the channels 36, overcoming resistance flat spring 37 pins 2 in the socket pads 8 (figure 4).

spring 28 is expanded. Then from cam 41 slider 35 is retracted to the right and the whole series of unspecified contacts clamped in channels 36 by a flat spring is removed from the pads, and the cutter from the horizontal movement mechanism from spring 12 and cam 39 is moved to the right and pusher 20 along columns 33, compressing spring 34 , moves the slider 35, as a result of which a row of contacts 2 from the action of the expander 38 is pushed out of the channels 36 into the tray 44 (Fig. 6). The cutter returns to its original position, and then the slider rises and moves to the left to its original position. The cycle is repeated.

From the described position of the assembly, the pads are moved to subsequent positions, including the control position for the presence of contacts, after which the pads with unassigned contacts are dropped into a separate container and then returned to the assembly. Uninstalled contacts, collected in tray 44, are periodically poured by the operator into the orienting storage device and again arrive at the assembly.

Thus, the device allows to ensure high-performance, high-quality assembly of contacts with insulator pads due to the use of blocking by the presence of the block in the mounting position and the use of the reset system of unidentified contacts without damaging them.
