Definitions

  • the invention relates to a method for producing an electrical connection between at least one line and at least one connection piece of a workpiece.
  • the connection piece is arranged on a workpiece surface and one end of the at least one line is prefabricated with a contact piece that is adapted to the connection piece.
  • the method comprises the steps: positioning the contact piece on the connection piece and welding the contact piece to the connection piece by means of laser radiation.
  • the invention also relates to a system made up of a workpiece carrier and a welding carrier and a device for carrying out the method according to the invention.
  • One such method is used to connect leads to switches such as a miniature snap-action switch.
  • the method should be capable of being automated, capable of being monitored, cost-effective and process-reliable.
  • the connection of the conductors to the switch must be of high quality to ensure a secure electrical contact between the wire and the switch.
  • Conventional methods for making electrical connections between leads and fittings of workpieces are based on soldering or resistance welding.
  • a method for producing an electrical connection between an electrical line and a connecting piece of a workpiece by means of laser radiation is known from the prior art, in which the laser beam is directed onto the workpiece.
  • the laser welding takes place without contact and without the help of additives.
  • the laser radiation will focused by means of an optics near the workpiece surface.
  • the position of the focus relative to the workpiece surface (above or below) is an important welding parameter and also determines the welding depth.
  • the absorbed laser radiation heats the joint surfaces of the parts to be welded (fitting and contact piece) and the temperature rises extremely quickly above the melting temperature of metal, so that a melt is formed.
  • the focused laser beam and the workpiece melts due to its energy.
  • One problem with laser welding is the limited ability to protect the surrounding workpiece surface, for example adjacent connecting pieces on the workpiece surface, or the workpiece as an electronic component itself, from damage caused by the direct laser beam or diffuse scattered radiation (e.g. excessive heating).
  • U.S. 7,630,768 B1 discloses the preamble of claim 1 and relates to a head assembly for connecting an implantable medical device to at least one lead terminating in a patient to be assisted by the medical device.
  • U.S. 2017/110805 A1 discloses an attachment method for attaching a terminal to a conductive pattern with a brazing filler metal interposed therebetween.
  • U.S. 5,269,056 discloses the preamble of claim 14 and relates to welding a plurality of stranded wire gauges with electrode pins and more particularly with a method and apparatus in which stranded wire of a first material is welded to an electrode pin of a second material.
  • EP 1 306 926 relates to a method for producing an electrical connection between a connecting piece of a workpiece and a line, the prefabricated end of the line being positioned on the connecting piece and being welded by means of laser radiation.
  • the invention is based on the object of presenting an improved method and an arrangement for producing an electrical connection and a device for carrying out the method. Based on the stated prior art, the object is achieved with the features of independent claims 1 and 14 and dependent claim 15. Advantageous embodiments are specified in the further dependent claims.
  • a straight line running along the laser radiation intersects a plane outside the workpiece that is predetermined by the workpiece surface. In other words, there is no intersection between the laser radiation and the workpiece surface.
  • this welding geometry is achieved in that the workpiece surface is inclined in the direction of a horizontal line and thus in a direction facing away from the laser source.
  • the use of a laser enables contact-free welding between the contact piece of the at least one line and the at least one connection piece of the workpiece, which does not require the use of additives.
  • the heat load on the workpiece which is designed, for example, in the form of an electronic component, is kept low by briefly irradiating the contact piece and connecting piece and without the laser radiation having a direct effect on the material surface.
  • the laser radiation generated by a laser source can be guided to the workpiece with mirror systems or optical fibers and then focused on the workpiece.
  • the workpiece In a welding cell, the workpiece is usually arranged on the floor or on a welding carrier, with the laser radiation radiating onto the workpiece surface from above (basic system).
  • a surface normal of the workpiece surface is aligned parallel to the laser radiation during welding.
  • the laser radiation intersects a plane in the workpiece that is predetermined by the workpiece surface, namely on the workpiece surface at the position of the connecting piece. In this case, the workpiece absorbs a large part of the laser radiation and heats up. In this geometry, it is also difficult to protect the workpiece surface from diffuse laser radiation.
  • the laser radiation intersects a plane defined by the workpiece surface outside of the workpiece, a surface normal of the workpiece surface points in a direction away from the laser source, i.e. no direct laser radiation hits the workpiece surface.
  • the workpiece surface is thus turned away from the laser source direction tilted. Due to this oblique alignment of the workpiece surface with respect to the laser radiation, the workpiece is protected as well as possible from damage by the laser beam during welding. In addition, the resulting scattered radiation is minimized by this measure. The minimization of scattered radiation is particularly desirable in order to also protect surrounding workpieces during welding.
  • an angle of intersection between the laser radiation and the plane defined by the workpiece surface is between 1° and 20°, more preferably between 5° and 15°, more preferably 10°.
  • the workpiece may be a miniature (snap) switch.
  • Miniature switches or microswitches are small switching elements that can be found in numerous electrical devices and attachments. They are used to switch current between two flux branches by means of a mechanical load or to switch electrical consumers on or off behind the switch. Such switches represent a cost-effective solution for switching electrical components.
  • a weld point between the fitting and the contact piece can be determined using an image processing system.
  • the image processing system enables a fully automatic control of the position of the contact piece and connection piece.
  • the contact piece and the connecting piece can be searched for and compared with the default images. If the contact piece is positioned correctly on the connector, the welding process can be started automatically. If the contact piece is not correctly positioned, the welding process is aborted. Each welded joint can be checked separately.
  • the welding point at which the laser starts the welding process is also determined via the image processing system. This can depend on the precise contact geometry.
  • a welding movement can be controlled by the laser, preferably the welding movement is a straight movement or a circular movement.
  • the control of the laser movement can alternatively be replaced by a control of the workpiece movement.
  • the type of movement varies depending on the switch or contact geometry and can be automatically adjusted by the image processing system.
  • the contact piece is preferably designed as a contact sleeve and/or the connection piece is designed as a contact pin.
  • the cross section of the sleeve opening can be adapted to the shape of the connecting piece.
  • the contact sleeve is preferably large enough to be able to accommodate the connection piece and small enough to prevent the contact sleeve from slipping off unintentionally.
  • the workpiece is used before welding in a workpiece carrier, wherein in an inserted state, the connector opposite a surface of the workpiece carrier protrudes.
  • the workpiece surface can essentially lie in one plane with the surface of the workpiece carrier.
  • a workpiece carrier is a carrier on which one or more workpieces are attached in order to transport them by a workpiece conveyor along a production line through several production stations.
  • the workpiece carrier can be designed in such a way that it accommodates a large part of the workpiece and thus protects it from scattered radiation, while the alignment between the laser radiation and the workpiece surface remains unaffected.
  • the workpiece carrier can have at least one guide groove for guiding the at least one line.
  • the line is thus fixed during the procedure and protected from the laser radiation.
  • the fixed cable also ensures that the contact piece does not slip off the connection piece before welding.
  • the at least one guide groove preferably extends in a direction substantially transverse to the laser radiation.
  • the guide groove can be so deep that it completely accommodates the line. In this arrangement, the cable is protected as best as possible from the laser radiation.
  • the workpiece surface is aligned (relative to the laser beam) during welding by arranging the loaded workpiece carrier on a welding carrier with an inclined welding carrier surface.
  • the orientation of the pre-configured workpiece carrier is effected by the sloping surfaces of the welding carrier in the welding cell.
  • the welding carrier can be part of the transport system, which is loaded with the workpiece carriers and moved into the welding cell by means of a transfer system.
  • the sweat wearer with obliquely trained The welding carrier surface offers a particularly simple and reliable way of specifying the alignment of the workpieces in the welding cell.
  • the welding carrier can have additional means that enable the workpiece carrier to be fixed in place.
  • a welding carrier is preferably equipped with at least two equipped workpiece carriers, the arrangement of the workpiece carriers being mirrored to one another. This arrangement enables a high packing density of the workpieces.
  • the welding carrier can have a depression in the middle, which ensures additional cooling in this area and/or deflects the reflected laser radiation in a predetermined direction.
  • the workpiece can have a second connection piece on the workpiece surface, one end of a second line being pre-assembled with a second contact piece adapted to the second connection piece, the second contact piece being positioned on the second connection piece, and the alignment between the laser radiation and the workpiece surface being both welds is the same.
  • This embodiment enables the method to be carried out as quickly and efficiently as possible.
  • the first and second contact pieces are preferably arranged offset from one another in a direction essentially transverse to the direction of the laser radiation. This allows the laser's focal plane to be maintained between welds.
  • the workpiece carrier preferably has a second guide groove for guiding the second line on the workpiece carrier, the second guide groove being L-shaped. The lines can thus be routed parallel to one another and mainly at right angles to the direction of the laser radiation.
  • the invention also relates to an arrangement comprising a laser source, a workpiece and a system made up of a workpiece carrier and a welding carrier for producing an electrical connection between at least one line and at least one connecting piece of a workpiece by means of laser radiation.
  • the workpiece carrier is designed to hold the workpiece

  • Essentially excess material of the connection piece 25a, 25b or contact piece 15a, 15b is used as the welding material.
  • Laser welding is preferred for producing an electrical connection, since only very short laser pulses are required and the thermal stress on the workpiece 20 is therefore relatively low.
  • the laser radiation intersects a plane defined by the workpiece surface 21 outside of the workpiece 20.
  • no direct laser radiation strikes the workpiece 20 or the workpiece surface 21 directly.
