Description

The invention relates to the production of radio elements with leads, and more specifically to special process equipment for the manufacture of wire leads and their installation in the sockets of the cassette, which serves as one of the parts of the mold during the subsequent molding of the shells of these radio elements by the injection method.

The purpose of the invention is improving the quality of work by increasing the reliability of fixing the findings.

The goal is achieved by the fact that the proposed device is equipped with a mechanism for vertical movement of the table for fixing the process cassette connected to the camshaft of the drive, and the wire feeding mechanism is rigidly fixed on the moving knife of the mechanism for cutting the leads.

Figure 1 shows the kinematic scheme of the device proposed; figure 2 - the proposed device (without a feed mechanism and drive), a general view; on fig.Z - section aa in figure 2.

A device for making wire leads of radioelements and installing them in the sockets of the process cassette contains a cam distribution mechanism consisting of shaft 1, cam 2 — wire feeding mechanism 3, cam 4 — controlling the table for fixing the technological cassette 5 with respect to the fixed knife 6, the cam 7 of the mechanics of the wire leads, as well as the cam 8 of the mechanism for the vertical movement of the table and the technological cassette 5. Intermittent rotation of the shaft 1 is provided from the electromotor 9 through the chain th transmission 10 and clutch actuators 1) j controlled by the limit switch 12.

The wire feeder from stores (not shown), the number of which corresponds to the required number of leads in the cassette 5, is made in the form of feed rolls 13, driven from the cam 2 by means of the lever 14, and a ratchet mechanism 15, by means of which the required feed amount is set.

The finished cut mechanism is a movable knife.

16, provided with wire apertures 17 and mounted slidably along the upper plane of the fixed blade 6

5 by pushing force

a knee-lever mechanism 18 connected via a pusher 19 with a cam 7.

The wire feeder with the feed rolls 13 is rigidly connected to the movable knife 16 by means of structural elements (not shown). To reverse the movement of the blade plate 16 together with the mounted

15 there is a return spring 20 on the wire feed mechanism.

Between the movable knife 16 and the feed rollers 13, additional guides are installed for drawing dies (not shown).

The guide channels 21, fixedly mounted in the case of the fixed knife 6, are coordinated in size and nature of their location with

25 sockets 22 for placing the wire leads of the process cassette 5,

Matching through holes 17 in the blade plate to 16 channels

30 to 21 of the fixed knife 6 is provided by their joint processing, and the accuracy of their combination with the process of work is provided by the stop 23.

To fix the position of the cassette 5

2, relative to the fixed knife 6

The table 24 serves for fixing the process cassette a fixed stop 255 as well as a clamping lever 26 connected to the cam 4. In the case of the stopper 25 there is a recessed pin 27 for acting on the limit switch 12.

The mechanism of vertical movement of the means for fixing the position of the cassette contains a pair of rigidly connected to each other by means of a pusher 28 columns 295 installed in the guides 30 with the possibility of acting through the stops 31 on the table 24 spring-loaded with respect to the fixed blade 6 to communicate the latter movement in accordance with the program defined by the profile dual cam 8, All basic - the mechanisms of the device are mounted - on the frame 32,

Cascore cassette works as follows.

In the initial state, the wire 3, passed between the feed rollers 13, passes through the additional guides, the combined through holes 17 of the movable knife 16 and the channels 21 of the fixed knife 6.

The technological cassette 5 to be loaded with wire leads is installed in table guides 24 and fed to stop 25 until it stops, acting through tongue 27 on limit switch 12 that turns on single-turn clutch 1 1 transmitting rotation from permanently connected motor 9 and chain drive 10 to shaft 1 distribution mechanism.

When the camshaft 1 is rotated through the cam 4, the pressing lever 26 is activated, which locks the cassette 5 in the desired position. Further, from the cam 8 interacting with the pusher 28 rigidly connected through the columns 29 to the stops 31, the table 24 is lifted with the cassette 5 based on it to the extreme upper position. Upon further rotation of the shaft 1, the cam 7 through the pusher (body 19 and the knee-lever mechanism 18 sharply shifts the movable knife 16 to the left, producing a piece of wire leads passed through the channels 21 of the fixed knife 6j along the line of contact of the movable knife 16 and the fixed knife 6. Produced a segment of conclusions, the movable knife 16 under the action of the spring 20 returns to its original position, in which the axes of the through holes 17 and the channels 21 are aligned.

Upon further rotation of the shaft 1, the cam 2 actuates the wire feed mechanism 3, and the cam 8 after a certain time interval, the mechanism for the vertical movement of the means for fixing the position of the cassette.

The lag time is set by assuming that the wire 3 passes at a given feed rate of a distance equal to the gap between the stationary foot 6 and the bottom of the slot of the process cassette 5 necessary to effect a guaranteed release.

Kicking the cut pins out of the cables 21 of the guide plate, as well as installing them with the ends in the sockets 22 of the cassette -5.

5 Next, the wire 3 is fed and the cassette 5 is lowered during Hei pToporo time synchronously, then the wire is stopped and the table 24 is lowered, spring-loaded.

10 with respect to the fixed knife 6 outside the contour of the cassette 5, I continues until the unloading of the cartridge filled with the wire leads of the cassette 5 is ensured

15 devices.

At the end of the rotation of the shaft 1 on the BRA, the cams 2,7,8 and 4 occupy the initial position, the clamping lever 26 is retracted under the frame 32, the holder cassette 5 is disengaged, and the single-turn coupling 11 is disconnected, disconnecting the shaft 1 from the drive.

Cassette 5 with 22 wire leads installed in its sockets

25 is removed from the device and transferred to the subsequent equipment of the technological line for the production of ra- / (iselement).

30 The spring-loaded tappet of the limit switch 1 2 returns the pin to its original position. A follow-up cassette is inserted into the device and the cycle is repeated.
