Definitions

  • the invention relates to a cutting device for a bonding machine with a cutting knife for severing a bonding wire, the cutting knife being directly or indirectly movably attached to a main movement device of a bonding machine in the vertical feed direction.
  • the invention further relates to a method for controlling the cutting movement of a cutting knife in bonding machines for at least partially cutting a bonding wire.
  • Cutting devices in bonding machines are known and are used for at least partially severing a bonding wire. It is known to provide cutting knives with separate drives in order to be able to move a cutting knife independently of a main movement device or to move the cutting knife directly with a main movement device.
  • the object of the invention is to provide a device and a method with which reliable control / regulation of the bonding force is achieved and which preferably also provide information about the degree of knife wear, that is to say about its current sharpness.
  • This object is achieved in that the cutting knife when placed on an at least partially cut wire by moving the Main movement device can be acted upon by a spring element with a cutting force to be exerted on the wire.
  • the cutting force results essentially from the static force effect which is achieved by means of the spring element.
  • a spring element e.g. a compression spring, leaf spring or the corpse
  • the spring element is preferably arranged between a cutting knife holder and an element of the main movement device, the cutting knife holder being movably mounted on the main movement device, in particular by means of a swivel joint, a linear guide or solid-state joints.
  • the range of motion of the cutting knife relative to the main movement device in particular with respect to a zero point position, can be determined by means of a sensor.
  • the speed of the knife with respect to the bonding wire can be known or can be determined.
  • the cutting force can thus be determined from the relative position of the cutting knife to its zero point position.
  • the force applied by the cutting knife to the wire can be determined from the position of the cutting knife in relation to a zero point position and a force characteristic of the spring element which can be tensioned by the movement of the cutting knife and by means of which a force is exerted on the wire via the cutting knife.
  • the speed of the cutting knife can also be incorporated into the force control.
  • the actual force can then be regulated, for example, by changing the position of the cutting knife relative to the zero point position and / or the speed of the cutting knife. This changes the deflection of the spring element and, depending on the force characteristic of this spring element, the force applied.
  • the force is also a function of the speed at which the knife moves relative to the bond wire. This speed can be determined on the basis of the speed of movement of the main movement device before it is placed on the bonding wire. After placement, the wire cuts into the wire due to the spring force, the main movement device being moved up to a set depth of cut in the Z direction. The cutting force can be permanently monitored during the cutting process. If this exceeds a maximum permitted value, the movement parameters of the main movement device must be adapted, in particular the speed can be reduced for this.
  • the cutting process and in particular a desired cutting force can be controlled and / or readjusted very precisely within wide limits.
  • a degree of cutting knife wear can be obtained.
  • a predetermined maximum cutting force is exceeded at or below a predetermined minimum cutting speed, it can be assumed that the knife is no longer sufficiently sharp and must be replaced due to wear.
  • this method offers the advantage, in addition to force control, that a knife can be replaced as required.
  • Figure 1 shows at least part of the main movement device 1 of a bonding machine.
  • the transducer 2 is attached to this (not shown here) with an ultrasound tool 3.
  • a cutting knife holder 5 is connected to the main movement device 1 via a swivel joint 4, so that they can move relative to one another.
  • a cutting knife 6, whose lower knife tip is cranked here, is attached to the cutting knife holder and points vertically downward to a bond point.
  • the cutting knife 6 is placed on the bonding wire, not shown.
  • the initial force essentially results from an overstroke of the main movement device 1 beyond this zero point position.
  • the spring 7 located between the cutting knife holder 5 and the main movement device 1 is compressed, so that a force which corresponds to the spring force acts on the wire 6 via the knife and cuts it.
  • the decisive factor for the effective force is the degree of compression of the spring, which is influenced by the speed of the main movement device and the sharpness of the knife.
  • Force or deflection can be measured by a position sensor 8, which determines the position of the knife 6 relative to the zero point position.
  • the current force can then be determined based on the force characteristic and e.g. in the event of a deviation from a desired force, the influencing variables, e.g. the cutting speed to be recalculated.
  • Figure 2 shows a section of the arrangement in an alternative construction from the front, where instead of a swivel joint, a spring steel connection was chosen in order to flexibly couple the knife holder and the main movement device with one another.

Abstract

L'invention concerne un dispositif de coupe pour une machine de connexion, comprenant une lame de coupe destinée à séparer un fil de connexion. Selon ladite invention, cette lame de coupe est fixée directement ou indirectement à un dispositif d'avance principal d'une machine de connexion, de façon à pouvoir se déplacer dans un sens d'avance vertical, et, une fois la lame placée sur un fil devant être au moins partiellement coupé, une force de coupe à exercer sur le fil peut être fournie à cette lame de coupe par le mouvement du dispositif d'avance principal au moyen d'un élément ressort. La présente invention concerne également un procédé de commande du processus de coupe.
