A device for soldering radioelements comprises a mechanism for supplying radioelements 1, a soldering mechanism 2, and a clamping mechanism for radioelements 3.

The mechanism for clamping the radio element contains a clamp 4, consisting of two elastic plates 5 and 6, mounted on a rod 7, in which there is a thrust rod 8. spring-loaded with a spring 9, connected to the bracket 10 by a screw 11 through the shoulder 12 and the pinion gear 13 located on the cuff 14 with an air cylinder 15, an arm 16 fixed to the base 17. The feed mechanism of the radio elements is made in the form of a conveyor of links 18 in the form of radio elements with holes for installing the ends of the conclusions of the radio elements and is mounted on the gear wheel 19. interaction uyuschem wheel 20 for transmitting motion through the boring bar 21, 22 in the carriage 23 through the movable guide 24 to the printed circuit board 25 (Figure 1, 5).

The curved section of the conveyor is fenced by a live roll consisting of a cage 26, a cylindrical shaft 27 and an axis 28. designed to fix

the radio element 29 during the passage of the circuit during loading and operation (Fig.1, 3, 4).

The soldering unit consists of two palms 30, mounted with the possibility of vertical reciprocating movement with the supply of solder through the unit of metered supply of solder 31. 32, fixed through the sleeve 33 to a pneumatic cylinder (not shown). The palms are connected by an arm 34 to a device on which the metered supply unit of solders 31, 32 and coils 35 are fixed, closed by a casing 36. The tips of the palms 37 are in the form of tubes through which a dose of molten solder enters the radio components (Fig. 5). The printed circuit board 38 is mounted on movable rails 39, secured by locks (not shown), and connected through the carriage 40 and the base 41 to the top of the device. The rotation of the housing is possible with a gear 42 and a coupling 43 for transferring the article to a table on which a longitudinal shaft 44 with a limb 45 is placed, as well as a transverse shaft 46 with a limb (not shown). To uniformly rotate the upper part of the device in three points at 120 °, the rollers 47 are disengaged (Fig. 1,5). At the bottom of the device there are power supply units 48 and pneumatic supply 49, designed to ensure the operation of the device. The device is equipped with compressed air and power distribution units to ensure the operation of all its components.

The device operates as follows.

After forming the radio element, the nodes return system is turned on, and the pneumatic cylinder 15 at this time starts the radio element reinstallation unit from the molding position to the loading position of the chain by lifting the rod 13 upward, the rod moves 180 ° about the axis.

The rod 13 rises, and the tape bar, moving back, rotates the rod 7 in the loading position of the chain (Fig. 1). The rod 13 lowers down and installs the radio element 29 in the chain link, while the rod 7 is brought up from the engagement zone by the pneumatic actuator 15. When the rod 7 is returned, an elastic plate 6 having a curved profile interacts with the link 48, and the thrust rod 8 by the spring 9 compresses the radio element 29 in the chain link (figure 2).

On the control panel, the forward chain is engaged by a predetermined size, i.e. to install the next radio element 29. The gear wheel 19 through the gearbox rotates the wheel 20 (Fig. 2), which is meshed with the conveyor link.

The loading cycle is repeated until the circuit is fully loaded (Fig. 1, 2).

The device is designed to load radio elements of 100-150 pieces of the same type, for a long cycle of work.

The transfer of the radio element 29 to the soldering zone is carried out by means of a boring bar 21,

22 and a pneumatic cylinder (not shown) to the carriage 23 through movable guides 24 to the printed circuit board 25 (Fig. 1).

The coordinates of the radio element 29 are set on the control panel according to the coordinates of the printed circuit board.

The soldering of the radio elements is carried out by reciprocating the movement of the pine trees to the place of soldering from the pneumatic actuator by means of coverage 33 (Fig. 1). The pilniks 30 are arranged in pairs, taking into account the sizes of the leads of the radioelements 29. When moving the pilniks to the soldering place, the dosed solder device produces

the supply of soft solder inside the housing to the tip 37, through the opening of which a molten mass of solder enters the terminals, while the rounded shape of the tip allows coverage of the lead

radio element to improve soldering quality.

To control the temperature of the tip of the greenhouse, the device is equipped with a greenhouse temperature control device that disconnects the greenhouse from the power supply at a temperature higher than the set temperature and turns on the greenhouse when it cools (Fig. 1).

After soldering the radio element 29 of the boring bar 22 by means of a pneumatic cylinder (not shown) returns to its original position, and the ladies 30 move up.

Process control is carried out from the control panel,

a command is sent to the housing to the longitudinal feed shaft 44 for a given installation and soldering size in the printed circuit board, its movement is carried out from the control panel. The soldering cycle is repeated.

Manual adjustment is performed by the dial 45 (Fig. 1), and the transverse movement of the housing is carried out by means of the shaft 46 (Fig. 1).
