Abstract

The invention relates to technological equipment for the production of electronic products. The aim of the invention is to expand operational capabilities. Substrate 5 by grab 15 rotates and is mounted on pads 28.29 alternately. The inductor 1 of the programmable robot moves the carriage 13 along the tray 12, ensuring the exact relative position of the sides of the substrate 5 with the segments of the tape 7c cut out in the stamp 8 by the output combs. The pusher 14. acting on the rods 27, attaches the segments of the tape 7 to the sides of the substrate 5. Before soldering, the substrate 5 is mounted on the tilter 10 and placed in a vertical position. Vacuum grip 16 removes the substrate from the overcoat 10 and sequentially immerses soldering devices 11 in each bath. After soldering, the substrate 5 is transferred to the cassette 20. To achieve this goal, the presence of a carriage 13 installed with the ability to interact with the robot, rods 27, pusher 14 and pads 28 , 29 with a mirror arrangement of the basing elements. 4 ill.

Description

The invention relates to the manufacture of radio equipment units, and in particular, to devices for mounting radio components on printed circuit boards.

The purpose of the invention is to expand the range of assembled products due to the possibility of attaching lead combs on the adjacent sides of the wafer substrates.

This goal is achieved by the fact that the machine is equipped with a carriage movable along the punch, installed to interact with the robot and equipped with spring-loaded rods, and a pusher of the said rods, on which two longitudinal and two transverse platforms are mounted for substrates with basing elements located specularly at each pair platforms of the same name and equipped with cutouts for output combs.

Figure 1 shows a General view of the machine; figure 2 - carriage, top view; in Fig.3 - section aa in Fig.2; figure 4 - tilter, section.

The machine contains a programmable robot with a linear drive, on the inductor 1 of which the working heads 2 and 3 are fixed, a cartridge magazine-feeder 4 for feeding the substrates 5 of the mounting plates, a mechanism for feeding the tape 7 with output combs, a stamp 8 for cutting sections of the tape 7, a fan heater 9 for preheating the substrates 5 before soldering, a tilter 10, a soldering device 11 mounted movably along the die 8 in the tray 12, the carriage 13 and the pusher 14. The working head 2 is equipped with a collet gripper 15, rotatable relative to the vertical axis. The working head 3 is equipped with a vacuum gripper 16, rotatable relative to the horizontal axis, and the latch 17. The cassette-feeder 4 consists of a conveyor 18, equipped with rails 19 for issuing cassettes 20 from the stack and receiving the cassettes in the stack, and a fixing platform 21. The stamp is equipped with a punch 22 and clamp 23 with needles 24, Tilter 10 has two forked planes 25 with clamps 26. The carriage 13 is equipped with spring-loaded rods 27 on which two longitudinal and two transverse platforms 28 and 29 with basing elements for substrates 5 are fixed, made in the form of clamps 30 and strips 31 and 32, in which slots 33 are made for output combs. Clips 30 and straps 31 are mounted mirrored at each pair of the same platforms 28 and 29, which makes it possible to save when connecting pieces of tape 7 to opposite sides of the substrate 5

unity of bases. To interact with the latch 17, a groove 34 is made in the carriage 13, and to facilitate the movement of the carriage 13, air lubrication channels are made at its base (on

not shown).

The machine works as follows.

The stack of cassettes 20 with substrates 5 is mounted on the conveyor 18, one of the cassettes enters the fixing platform 21. With the collet gripper 15, the substrate 5 is taken from the corners and transferred from the cassette 20 to one of the platforms 28.29, while the substrate 5 is rotated so that the base side of the substrate was adjacent to the bar 30. The mechanism 6 is turned on and feeds the tape 7 into the stamp 8. The clip 23 is lowered and fixes the tape 7 through the perforation holes with needles 24. The punch works

0 22 and cuts out a section of tape 7. The latch 17 is installed in the groove 32 of the carriage 13, the inductor 1 moves the carriage 13, ensuring the exact relative position of the substrate 5 and the section of the tape 7. The pusher 14 is activated and the section of the tape 7 is attached to one side of the substrate 5 The clip 22 is lifted and the substrate 5 is pulled away from the die 8. In the same sequence, the segments of the tape 7 are joined to the other sides of the substrate 5. Then, the substrate 5 with a collet gripper 15 is mounted on one of the platforms 25 of the tilting device 10. The fan heater 9 is turned on and the substrate 5 is heated. At this time, segments of the tape 7 are connected to another substrate 5 and installed on the tilter 10. The tilter 10 is moved to the vertical position. Inductor 1 establishes a vacuum grip 16 in the groove of the pad 25, when moving forward, removes the heated substrate 5 from the pad 25 and immerses each side in batches with flux and solder of the soldering device 11. After

5 of soldering, the inductor 1 moves in the opposite direction and sets the substrate 5 in a vertical position on the tilter 10. The tilter is moved to a horizontal position. Ready substrate 5 collet 15 is transferred to cartridge 20. The cycle is completed.

The machine is equipped with a set of interchangeable pads for standard sized substrates and has the ability to quickly re-set without adjustment.

If necessary, the machine can be integrated into the circuit board assembly line.
