Description

 The invention relates to soldering with a dosed supply of solder in the form of a tape, mainly small diameter wires for mechanized soldering of the outputs of various radio electronic elements, and can be used in radio engineering, electronic and instrument making industries in the production of radioelectronic equipment units,

The aim of the invention is to simplify the design of the device.

Figure 1 shows the mechanism for moving the solder wire; FIG. 2 ™ is a section A-A. FIG. 1; FIG. 3 shows the location of the wires supplied by the solder relative to the working surface of the paed; FIG. 4 is a diagram illustrating the insertion of discs on an axis when changing the diameter of the solder wire,

The device comprises a bracket 1 with a side removable cover 2 on which shaft 3 is mounted with a driving roller 4 located on it. The driving roller 4 is connected with supporting (pressure) discs 5 located on an axis 6 fixed in the cage 7s moving in a direction slm in the housing 8 with an adjusting screw 9 and a gland spring 10. Between the disks 5 on the axis 6 there are inserts 11 separating the disks 5 from each other. Between each disk 5 in its groove and the drive roller 4 there is a soldering wire 12 moving around. The bracket 1 is attached to the gearbox housing 13, the shaft 14 of which is connected to a drive (not shown), and the shaft 3 of the driving roller 4 is connected to the gear 13, the wire is fed to the working surface of 15 pa of flax,

The disks 5 are each made with a hole diameter greater than the diameter of the axis 6, and there are located on it an ex

centrically with a part of the internal surface of the holes freely supported on the axis 6 (Fig. 2).

The device works in the following way.

The rotation of the shaft 14 from the actuator (not shown) is transmitted through the gearbox 13 to the shaft 3 with the drive roller 4. As the supporting disks 5 are pressed to the drive roller 4, from its rotation, the Solok propeller 12 moves in the direction to the blade (not shown ) and rotate the reference DIS1SH 5. The force of the clamping 5 to drive the roller 4 is regulated by screwing (unscrewing) the screw 9 into the yoke 7,, Tsiski

12 between the drive roller 4 and the supporting discs 5. The solder wire 12 is moved until the workpiece (not shown) of the sections (doses) of the required length is obtained from the working surface 15 (Fig. 3). After that, the transmission of rotation from the drive (not shown) through the shaft 4 to the drive roller 4 is stopped. The moving solder wires 12 are positioned transversely relative to the working surface of 15 pels of flax.
