The distance between the working surfaces of the stops 36.37 is a multiple of an odd number of steps of the step feed. The steps of the toothed rack 24 and the signal comb 21 are equal to two steps of the step feed. The signals from the comb 21 and the programmers of the pressing 22 and the cutting 23 are removed by slotted photosensors 41, 42 and 43, respectively. The program carriers 22, 23 consist of a housing 44, pins 43 with two grooves and ball locks 46, the number of pins 43 corresponding to the maximum the number of contacts or cuts - assembled insulator.

The pneumatic cylinder 32 is much smaller in diameter dra 33

The knife 60 of the cutting mechanism 6 is made in the form of a trapezoid with side cutting edges, a longitudinal groove and an end bevel forming the safety device for entering the groove 61 between the cells 62 under the contacts 3, for cutting the insulator 8 The cutting mechanism 6 is equipped with slot photo sensors 63, 64 of the upper and the lower position of the Knife 60 connected to the rod of the pneumatic cylinder 63,

The sorting mechanism 7 is made in the form of a gutter 66, at the end of which plates 68 are staggered over the discharge chutes 67 with step lengths corresponding to the cutting program of insulators 8. For unloading insulators 8 of slot 1 to the viewing platform of chute 66, the sorting mechanism 7 has motor 69, cam 70, slider 71, slit photo sensor 72, interacting with flag 73, Under diverter 67

boxes 74 are installed for connectors of various assembly patterns. For the connector module (within the whole isolator), the box 75 is installed with the error of contact set 5.

The electronic control unit and the pneumatic unit (not shown) use slotted sensors and limit switches to control electric motors and pneumatic cylinders.

The machine works as follows.

In the initial state, the longitudinal movement carriage 18 is in the leftmost position, and the lateral movement carriage 17 is in the rearmost position. The top layer of insulators 8 in the cassette 9 is pressed by the load 12 through the pusher 10 to the front wall of the tray 1. When the pneumatic cylinder 28 is fed into the left cavity by the command from the limit switch 26 through the pneumatic unit and the electronic control unit (not shown) the longitudinal carriage 18 begins the stepping movement to the right. This is ensured by the fact that the slit photosensor k 1 is darkened and illuminated by the signal comb 21 through the step feed step, the pneumatic cylinder AO of the retainer 19 controlled by it always pulls one of the stops 36,37 to which the toothed rack 24 is attached. the action of the springs 38 enters the groove between the teeth of the toothed rack 24 before the first stop is extended. The movement of the longitudinal carriage 18 to the right provides simultaneous step-by-step movement of all isolators. The ditch 8 located on the tray 1 between the spring 1 of the grippers 15 and the piece-by-piece separation of the insulators 8 from the upper layer of the cartridge 9 at the expense of the plan ki 20. After the movement of the longitudinal movement carriage 18 to the right, the limit switch 27 operates and gives a command to the pneumatic cylinder 31 to move the carriage 17 transversely forward. Upon completion of the forward movement of the carriage 1, the limit switch 30 is activated and a command is given to the pneumatic cylinder 28 for movement, the longitudinal movement carriage 18 is left. When the carriage 18 is completed, the limit switch is actuated and the command to the pneumatic cylinder 31 is given to move

carriages 17 transverse movement back. The motion cycle for the length of the insulator 8 is completed, all insulators 8 placed in tray 1 are intercepted. The clamps 16 in the tray protect the insulators 8 from displacement. After the layer of insulators 8 is in operation, the limit switch 14 is triggered, the motor 11 is commanded, the pusher 10 moves back to the stop, the limit switch 13 is triggered, the command to raise the cassette 9 is given, in increments between rows of insulators 8 (the mechanism for lifting the cassette is not shown ). Upon completion of lifting the cassette 9 to a pitch, the electric motor 11 is turned off, and the pusher U at the expense of the load 12 presses the next layer of insulators 8 against the front wall of the tray 1.

The program of the necessary assembly and cutting schemes is typed by extending the pins 45 of the program carriers of the pressing 22 and cutting 23. When the pin 45 of the program carrier of the pressing 22 or cutting 23 overlaps the slit of the photosensor 42 or 43, a command to ban the step-feed is issued, the pneumatic cylinders 52 and 53 trigger the pre-pressing 2 and repressions 3, and from the pneumatic cylinder 65, the cutting mechanism 6 is activated.

The contacts 5 from the orientation mechanism 47 by the vibrating tape drive 48 under the pressure of the contact column 5 enter the window of the preliminary pressing mechanism 2, are individually separated by the gate gate 51 and, according to the assembly scheme set by the program carrier 22, are installed into the cells of the isolator 62 62. Gateway 51 and synchronous with it The punch 54 of the depressing mechanism 3 is fed to the lower position, while the slit photo sensor 50 issues a command for switching the pneumatic cylinders 52 and 53 to return to the initial upper position. When the pneumatic cylinder 52 is returned, the slit photo sensor 49 lifts the step-feed ban. A similar sequence of commands is carried out in the cutting mechanism 6 by slit photosensors 63.64.

When moving down, the punch 54 of the mechanism 3 of the pressing of the stop 56 interacts with the cam 55, the working end of the punch 54 captures the shank of the contact 5, levels its position with a transverse movement and at the end

The code presses pin 5 into Isolator 8.

The knife 60 of the cutting mechanism 6, when moving downwards, enters the lower end of the 5 part of the insulator 61 of the insulator unopened by the contact bending and due to the presence of the Longitudinal groove, without touching the contour KTA with lateral cutting edges. From inside it cuts the jumpers between jji4eiiKaMH 62.
