Description

(54) DEVICE, FOR THE INSTALLATION OF WIRES ON THE INSTALLATION BOARD

one

The invention relates to equipment for the manufacture of blocks of electronic equipment, in particular for the installation of wires and harnesses on printed circuit boards.

Known devices for mounting wires, comprising a cut-off mechanism, a two-coordinate table and a fixing head l .ig

The device carries out the installation of a wire, the valley of which does not exceed the course of the two-coordinate table, the density of installation is limited by the fact that only one wire can be fixed at one point on the circuit board. When mounted on the ends of the wire, U-shaped loops are formed, which are fixed in the corresponding holes of the circuit board; the ends of the loops remain above the circuit board. and may fall into other attachments for fastening. Therefore, the device has a low reliability, since the previously fixed wires 25 can be pulled out when securing the last wires.

It is also known a device for mounting wires on a circuit board, comprising feed mechanisms and wires, a two-coordinate table for Q.

placing a circuit board, a fixing head located above it, with a hollow needle provided with a receiving part, and a gripping mechanism located under the circuit board 2.

However, the known device is inefficient, as it does not provide for the installation of wires, the length of which exceeds the course of the two-coordinate table.

The purpose of the invention is to increase the productivity of work by allowing the installation of wires whose length exceeds the course of the two-coordinate table.

This is achieved by the fact that a device for mounting wires on a circuit board, containing a feed mechanism and wire segments, a two-coordinate table for accommodating a circuit board, above which is mounted a fixing head with a hollow needle, provided with a receiving part, and a wire grip fastener located under the circuit board, equipped with a clamping mechanism, wires located above the circuit board, and the wire section mechanism is located above the installation;

Noah between the feeder and 3 wires.

FIG. Figure 1 shows the mechanisms of the device in position after moving the circuit board to the first point; Fig, 2 - the same after the segments prrvoda; in fig. 3 after the clamping of the wire above the circuit board / in FIG. 4 - the same after moving the circuit board to the second point; on. FIG. 5 is the same after sewing the circuit board at the second point in FIG. b - the same after performing a surge.

 The device for mounting the wires comprises a wire feeding mechanism i consisting of a coil 2 with wound on. its wire 3 and the feed rollers 4, the mechanism 5 pieces of wire reciprocating action, the mounting head b attached to it with a hollow needle 7 with the receiving part 8, two-sided 9 9 fixed to it on the circuit board 10, myhm 11 capture, located under the circuit board. The clamping mechanism 12 located above the circuit board.

The device works as follows. .

To secure the wire 3 on: the circuit board 10 at two points, the latter is moved with the help of the two-coordinate table 9 to the position where the first point is under the cannula 7 (see Fig. 1). The fixing head 6 is moved to the lower position while the floor of the needle 7 passes through the mounting board 10 and the mechanism 11. When the axis of symmetry of the receiving part 8 of the NEEDLE coincides with the direction of movement of the wire 3 (axis 1-1); The mechanism 1 serves the full predetermined length of the wire through the hollow needle 7, while the rollers 4 wind the wire from the coil 2 and feed it through the receiving part 8 and the hollow needle 7. After the wire is fed by the mechanism 5, the wire is cut off. Raise mounting head

in the dry position, and when the cannula 7 leaves the mechanism 11, the latter seizes the hole, after which the fastening head B moves Vyerh relative to the wire. After the arrival of the mounting head 6 in the upper position in the hollow needle 7 osta746978

atsya end of the wire. The mechanism 12 clamp the wire under the hollow needle above the circuit board with a force exceeding the force of gripping the wire by the mechanism 11 gripping the wire. The mechanism 5 segments return to its original position. The two-coordinate table 9 moves the mounting plate 10 so that the second connection point is under the hollow needle 7. At the same time, the wire 3 is pulled from the first one. After that move the mounting golovtsu b down. When the cannula 7 passes through the mounting plate. The wire 10 at the point where the needle exits is deformed. The deformation of the wire ensures its fixation with respect to; and-7, therefore, with the further movement of the hollow needle down the wire draws from the first point, with the floor. the needle passes through the circuit board 10 and the wire gripping mechanism 11. The fastening head 6 is moved upwards. When the cannula 7 leaves the wire gripper mechanism 11, the latter holds the wire.
