Description

The invention relates to process equipment, in particular, to devices for preparing radioelements for installation, and can be used in the radio engineering, electronic and instrument-making industries of the industry in preparing radioelements with axial leads for mounting to printed circuit boards overlap, including multilayer printed circuit boards with uneven arrangement of contact pads.

A device for flexible axial leads of radio elements is known, comprising coaxially mounted conveying drums with grooves for placing the leads of radio elements, spring-loaded bending rollers and a drive mechanism, with profiled grooves in which the bending rollers 1 are placed on the outer end surface of each of the conveying drums.

However, this device does not provide preparation of radio elements with axial leads for mounting on printed circuit boards overlapping, preparation of conclusions with differently flexible for mounting them on multilayer overlapping printed circuit boards and preparing for mounting radio elements of various sizes.

It is also known a device for forming radio element leads, comprising a transporting rotor with jacks for driving radio elements and a mechanism for shaping and trimming leads with punches and knives associated with a drive mechanism, as well as an additional plug for bending one of the terminals parallel to the body of the radio element, which can move perpendicularly the plane of the transporting rotor, and the knives for forming and trimming the leads are installed with the possibility of separately adjusting their position relative to nsportiruyuschego rotor 2.

A disadvantage of the known device is the inability to obtain flexible leads at a right angle to the body of the radio element and bend their ends parallel to the body of the radio element to be installed on the pads of the printed circuit boards overlap, as well as the impossibility of obtaining a different high bending of the ends of the leads of the radio element relative to the longitudinal axis of its body to be mounted. overlay laminated PCBs.

The purpose of the invention is to increase productivity in work.

The goal is achieved by the fact that in a device for forming and trimming the conclusions of radio elements, containing a transporting drum with holders of conclusions of radio elements, a mechanism for molding and trimming conclusions with bending punch and trimming knives, punches of an additional bend

pins parallel to the body of radio elements mounted on elements adjustable with respect to transporting the drums, adjustable elements made in the form of cylindrical ring holders mounted on the transporting drum with the possibility of simultaneous rotation, and punches for additional bending of the terminals parallel to the body of radio elements

external cylindrical surfaces

clips in a circle with the ability to interact with bending punches.

FIG. 1 shows the device, a general view; in fig. 2 is a cross section YES to FIG. one;

in FIG. 3 and 4 - ring holder; in fig. 5 and 6 show the technological sequence of forming the findings of the radio element by the proposed device.

The device comprises a fixed frame 1, a movable frame 2, in which

a drive shaft 3 is installed with conveying drums 4 and 5 and a roller 6. On each of the conveying drums 4 and 5 a cylindrical ring holder 7 is mounted coaxially with it and there is a rim 8 with a groove for accommodating the output of the radio element 9. Each holder 7 is mounted on a corresponding To her, drum 4 and .5 can be rotated relative to the drum, secured thereto by screw 10 and is able to rotate together with the drum. On the outer cylindrical surface of each clip 7, punches 11 of an additional bend are fixed in a circle and rims 12 with cams 13 are made.

On the roller 6 are sleeves 14 and

15, each of which contains a lever 16 and a lever 17 spring-loaded with a spring 18 (FIG. 2). On the lever 16, a roller 19 is installed (FIG. 2) cooperating with the cams 13 of the sleeve 7, and a bending punch 20 is attached to the lever 17.

Racks 21 and 22 are attached to the frame 1 and 2, respectively, on each of which a cutting knife 23 is fixed.

The device works as follows.

In the initial position of the device, the transporting drums 4 and 5 are positioned in such a way that one of the slots for outputting the radio element 9 of the rim 8 of each drum is in the loading position of the radio element 9, the bending punches 20 are retracted from the ring holders 7, the rollers 19 of the levers 16 under the action of the spring 18 abut in the cylindrical surface of the corresponding rims 12 ring clips 7.

The sleeves 7 are mounted and secured on their respective transporting drums 4 and 5 in such a way that the additional folds mounted on the sleeves are spaced from the slots for the output of radio elements at distances defining the depth of the U-shaped bending of each output of the radio element 9. At the loading position of the radio element 9 it is installed by leads into the slots of the respective transporting reels 4 and 5 and is held in the recesses of the retainer (not shown). After that, transporting drum 4 and 5 from the actuator (not shown) of the shaft 3 is in motion, for example, clockwise, and the radio element 9 is delivered to the flexible zone of its conclusions. When the transporting drums 4 and 5 are rotated, the rims 12 and the cams 13 of the clips 7 roll around the rollers 19 of the levers 16, the sleeves 14 and 15 rotate on the roller 6, the bending punch 20 is brought to the clips 7 and stand against the bending dies 7 11. First, U-shaped punches 20 are made with U-shaped flexible leads of radio element 9, and then with further movement of transporting drums 4 and 5 punches of additional bending 11 together with bending poins. 20, the final flexible leads are made. of the radio element 9. At the final stage of the final flexible conclusions of the radio element 9, the rolling of rollers 19 with the cams 13 ends ends, and the levers 17, under the action of the forces of the compressing springs 18, retract the bending punches 20 from the clips 7, presented the transport drums 4 and 5 the possibility of further movement, and the cutting drums the knife 23 - to cut the conclusions of the radio element 9. At this point, the other grooves for the conclusions of the radio elements on the transporting drums 4 and 5 are at the loading position, the new radio element 9 is set

7 into the slots of the respective transporting reels 4 and 5, which are delivered to the bending zone of its terminals, and the radio element with the formed leads is delivered to its unloading position in a container (not shown) and all further operations are repeated. The device is rearranged to form the output of radio elements of other sizes by moving the shaft 3 of the page 2 and the drum 4 in the axial direction relative to the frame 1 and the drum 5. The height of the U-shaped flexible of the terminals of the radio element 9 as well as their different bending are adjusted by moving the additional bends 11 of the bend relative to the grooves for pins on transporting drums 4 and 5 by turning the clips 7 on drums 4 and 5. Execution in the proposed device for forming the pins of radio elements of moving elements of the bend full-time matrices in the form of cylindrical annular clips mounted coaxially on the transporting drums with the possibility of turns relative to the drums and joint movements with them, as well as fixing the bending dies in a circle on the outer cylindrical surfaces of the clips and making cams of them on them when installing the bending punches on the movable brackets made, for example, in the form of swinging arms, interacting with cam loops, provides, in comparison with known devices, the ability to regulate the height of the U-shaped are flexible, the pins are flexible and the adjustment process is simplified, as well as the possibility of differently high pins of the radio elements of the d-1 to be mounted on the multilayer printed n.ui with the arrangement of the contact pads on different board levels.
