Definitions
- the invention relates to a device for cutting and bending connecting wires of electronic components during their assembly on printed circuit boards by means of lower tools.
- the connecting wires are pressed against the printed circuit board bore after the cutting process and cut to length from a bending jaw, and are thus bent over.
- the consequence of this is that, due to relatively small position inaccuracies between the hole in the circuit board and the bending jaw, poor bending results are achieved, conductor tracks are damaged, short circuits occur or the electronic components can fall out of the circuit board.
- the invention is based on the object of providing a lower tool which enables a defined cutting to length and an error-free bending of connecting wires of electronic components when they are mounted on printed circuit boards, a secure mounting of the components being guaranteed until soldering in and no short circuits occurring .
- This object is achieved by using a device in which a first cutting and bending jaw with a Cutting edge and at least one gripping prong and a second cutting bending jaw with a structure, a bending edge, an edge and a surface are present, the cutting edge interacting with the edge, the gripping prongs interacting with the surface, the connecting wire being bent around the bending edge and in a connecting wire can be cut to length and bent in one operation.
- the invention is based on the finding that exact cutting to length and a defined bending of connecting wires is possible by means of two counter-bending jaws acting against one another without any force being exerted on the printed circuit board or the bore therein.
- This produces a solely '1 between the two cutting-bending jaws flow-off allows fender cutting and bending operation, wherein a terme ⁇ certain turning angle is a cutting-bending jaw achievable by the configuration of the surface.
- the positioning between the lower tool and the bore takes place in relatively large tolerance ranges.
- a predetermined distance between the underside of the circuit board and the interface at which the connecting wire is cut to length is set by the construction of a cutting and bending jaw on which the printed circuit board is placed.
- the construction of the device according to the invention is simplified by a pivot point common to the cutting-bending process for both cutting-bending jaws.
- the lower tool is rotatably mounted for targeted adjustment of the bending direction of the connecting wires.
- Figure 1 shows a device with circuit board and component in the starting position.
- FIG. 2 shows a device corresponding to FIG. 1 in the working position.
- Figure 3 shows a device in the end position.
- the first cutting and bending jaws 1 shows a first cutting-bending jaw 1 and a second cutting-bending jaw 2 together with a printed circuit board 13 and an electronic component 12 and an associated connecting wire 14.
- the circuit board 13, which is usually made of plastic, has the bore 11.
- the stops 9 ensure a defined end position of the two cutting and bending jaws 1, 2.
- the first cutting and bending jaws 1 has a cutting edge 3 which interacts with the edge 4 of the second cutting and bending jaw 2 for the cutting process.
- the bending edge 6 interacts with the gripping prongs 10, the connecting wire 14 being bent until it rests on the surface 7.
- the turning angle is determined by the inclination of the surface 7.
- the common pivot point 8 of the two cutting and bending jaws 1, 2 is indicated in the drawing.
- FIG. 2 shows the device in the working position, the second cutting-bending jaw 2 having already been guided up to the stop 9.
- the spacing X between the interface, defined by the cutting edge 3 and the edge 4, and the underside of the printed circuit board 13 is thus set by the structure 5.
- the circuit board 13 rests on the cutting and bending jaws 2.
- the first cutting-bending jaw 1 is still moving towards the stop 9 in the snapshot shown.
- a fixed stop for the circuit board 13 can be attached to the lower tool in such a way that the bending edge 6 of the cutting and bending jaw 2 is in contact with one another defined distance of 0.1 mm below the circuit board.
- FIG. 3 the cutting and bending processes have ended.
- the connecting wire 14 is cut to length, lies against the surface 7 and is bent around the bending edge 6. In this state, the first cutting and bending jaw 1 also abuts the stop 9.
- a more or less strong notch in the connecting wire 14 is achieved by the first cutting-bending jaw 1 by means of the gripping prongs 10.
- This notch effect ensures that the wire is positively gripped during the bending process and is bent in a defined manner around the bending edge 6 of the second cutting and bending jaw 2.
- a sliding of the connecting wire 14 upwards is thereby ruled out, even with low component holding forces, such as in the case of manual assembly.
- Another advantage of this indentation by the gripping prongs 10 results in the further processing in a subsequent soldering process.
- the solderability is increased by tearing open oxide layers that may be present on the connecting wire 14.
- the use of the gripping prongs makes it possible to process connecting wires 14 with different diameters. With relatively small jaw forces, wire diameters of, for example, 0.3 to 1 mm can be processed, round and rectangular cross sections being possible.
