SU759289A1 - Automatic machine for mounting parts such as pins in the openings of base members - Google Patents

Description

The invention relates to the assembly production and can be applied mainly in the field of radio and electronic production, in particular when installing the collector output in the hole of the transistor leg.

Known machine for installing pins in the holes of the housing parts, containing mounted on the basis of the feed mechanism parts, the orientation mechanism of the body parts and the driving mechanism of the pins, kinematically connected with the camshaft Sch. This. the machine provides for the installation of pins in the holes for landing with tension.

According to the technology of assembling the transistor legs with collector leads *, it is necessary that there be a gap between the lead installed in the hole of the yoga transistor and the walls of this hole to get a good weld due to the penetration of molten solder into this gap. Known machine does not provide such an installation of pins.

The aim of the invention is to provide the possibility of installing the leads in the holes of the legs of transistors \ under the subsequent soldering due to the obtaining of longitudinal gaps between the leads and the hole of the legs tightly fitting it into the hole.

This goal is achieved due to the fact. _ Go, chto- / machine equipped with kinematically connected with the camshaft "i'USPHAIev / l'yenyym’ "on /" Yonbv'ayyy before the driving mechanism of a mechanism to perform in the hole of the leg alternating longitudinal projections

15 and hollows. This mechanism can be made in the form installed in the housing with the possibility of rotation and axial movement of the spindle associated with the camshaft

20 and the punch fixed in it

performed, for example, triangular.

FIG. 1 shows the machine, a general view? in fig. 2 is a section A-A in FIG. one; in fig. 3 - section BB

25 in FIG. 2? in fig. 4 - product with a clogged pin.

The machine consists of 2 mounted on the base of 1 rotary table with sockets for accommodating the cor30 of the trigger parts - transistor legs

ditch and 2 ______ mechanism installed around the table; 3 orientation legs

a hole in the desired position, the mechanism 4 execution in the holes of the legs of alternating longitudinal projections and depressions and the mechanism 5 driving the conclusions. The base also contains a mechanism for feeding the legs, made, for example, in the form of a vibration hopper with a tray 7, a mechanism 8 for feeding the leads and a receiving table 9 with a tray 10 for assembled products. The mechanism _____4 is made in the form of a spindle 11, which is placed in the slider 12 about the possibility of rotation from the gears 13 and 14. The slider 12 together with the spindle 11 and the roller 15 moves' relative to the body 16 from the cam 17. The gear 14 and cam 17 receive rotation from the camshaft (not shown), for example, a chain transmission 18. In the spindle 11, a punch 19 is fixed, having a triangle shape in cross section.

The rotation of the table 2 is carried out by any known mechanism of periodic rotation, for example the Maltese one.

The machine works as follows: ZOM.

. From the vibrating hopper b on the tray 7, the case part 20 - the transistor leg enters the turntable's socket 2 and is transferred to the position

'to mechanism 3, where it is oriented with a hole to the desired position and fixed. Fixed in the socket member 20 following rotation of the table 2 is moved to the mechanism 4, _T de its opening is inserted with interference triangular punch 19 attached to the spindle 11. On the walls otverstiYavypolnyayutsya alternate troughs 21 and longitudinal ledges 22. The gears 13 and 14 and the cam profile 17 selected in such a way that the time spent in the hole, part 20, the punch 19 turned no more than 60. After processing the hole with the punch 19, the part '20 moves to the position of the mechanism

'5, where the output is clogged in the hole

23, coming from the terminal feed mechanism 8. The output 23 is held in the hole with tension between the protrusions 22 of the part 20, and the troughs 21 between the wall of the hole and the output 23 provide for the passage of the molten solder during the subsequent junction. Then the assembled product arrives at the pickup position, is released from the -θ nest and 'moves along tray ¹ to the receiving, table 9.
