The invention relates to a cutting device, for a bonding machine, with a cutting blade for separating a bonding wire, whereby the cutting blade is directly or indirectly mounted on a main displacement device of a bonding machine, such as to be displaced in a vertical projection direction. On placing the cutting blade on a wire for at least partial cutting, by displacement of the main displacement device the cutting blade may be applied with a cutting force for application to the wire, by means of a spring element. The invention further relates to a method for control of the cutting process.
Description
Cutting knife the present invention relates to a kind of cutting equipment, comprises a cutting knife that is used to cut off closing line (Bonddraht), on wherein can directly or indirectly be fixed on main motion device in conjunction with machine along the vertical feed direction with moving in conjunction with machine (Bondmaschine).In addition, the present invention relates to a kind of method of in conjunction with machine, when small part is cut closing line, controlling the cutting knife cutting movement.
In conjunction with the cutting equipment in the machine is known, and they are used for cutting off closing line to small part.Well-known in this respect is that cutting knife is provided with independent drive unit, so that can irrespectively drive cutting knife with a main motion device, or directly drives cutting knife by a main motion device.
These two kinds of methods all do not provide the accurate information about actual force on closing line, thereby can only not control or adjust cutting force so satisfactorily.
The purpose of this invention is to provide a kind of equipment and a kind of method, can reach control/adjustment adhesion (Bondkraft) reliably, and they preferably can also provide the arthrotome degree of wear by them, that is the information of the current acutance of relevant cutter.
For reaching the measure that this purpose takes is that when cutting knife rested on the closing line that will partly cut at least, by the motion of described main motion device, this cutting knife can apply a cutting force that acts on the closing line by a flexible member.
Since described power be not directly by described main motion device but by a flexible member for example compression spring, leaf spring and so on apply, the stress effect that comes from the static state that obtains by flexible member basically produces cutting force.With respect to main motion device or a move distance and a described flexible member decrement or a span more or less associated therewith, can change described active force according to cutting knife with respect to the fixed dead-center position of this main motion device.
In order to reach this point, preferably flexible member is arranged between the member of a cutter supporter and described main motion device, wherein, this cutter supporter especially is contained on this main motion device movingly by a rotary gemel, a straight line guiding device or solid hinge.
By favourable design, cutting knife especially can be determined by a sensor with respect to the move distance of a dead-center position with respect to the main motion device.Equally, cutter can be known maybe measuring with respect to the speed of closing line.
Therefore, by determining cutting force with respect to the relative position of its dead-center position according to cutting knife according to equipment of the present invention.For this reason, can be that can tighten by the motion of cutting knife and power is applied to the power characteristic curve of the flexible member on the closing line via cutting knife with respect to the position of a dead-center position and one by it according to cutting knife, determine to be applied to power on the closing line by cutting knife.
Determine the described power except position, the speed of cutting knife can also be used in the lump the adjustment of described power by cutting knife.
After determined actual forces and a nominal force or a nominal force interval are compared, can for example adjust actual forces with respect to the position of dead-center position and/or the speed of cutting knife by changing cutting knife.Change the amount of deflection of flexible member thus and also change applied force based on the power characteristic curve of this flexible member.
This power is the function of cutting knife with respect to the movement velocity of closing line equally.This movement velocity can rest closing line at cutting knife and go forward to determine by the movement velocity of described main motion device.After on putting, cutting knife is based in the elastic force incision closing line that is acted on, and at this moment, described main motion device moves to a depth of cut of adjusting along the Z direction always.At this moment, in cutting process, monitor described cutting force sustainably.If cutting force surpasses a maximum permissible value, then must adjust the kinematic parameter of this main motion device, especially can underspeed for this reason.
According to the present invention, described cutting process and especially desired cutting force can be controlled very exactly to a great extent and/or be adjusted.
By determined cutting force and cutting speed are compared with minimum and maximum cutting force of being scheduled to or cutting speed, can know the degree of cutting blade abrasion.Especially when surpassing a predetermined maximum cutting force and be near or below a predetermined minimum cut speed, can conclude that thus cutting knife has no longer included enough acutancees, and must change owing to worn and torn.
Compare with the method that hitherto known the quantity according to certain cutting process is changed cutter, the inventive method also has such advantage except control/adjustment power, that is, cutter can be changed as required.
By the accompanying drawing illustrated embodiment the present invention is described in detail below.
Fig. 1 and 2 represents according to method and apparatus of the present invention.
Fig. 1 represents at least a portion in conjunction with the main motion device 1 of machine.On this part, fixing the converter 2 (not expression in detail among the figure) that has a ultrasonic tool 3.
A cutter supporter 5 is connected with described main motion device 1 by a rotary gemel 4, and therefore, they each other can relative motion.On this cutter supporter 5, be fixed with a cutting knife 6 that points to binding site (Bondstelle) vertically downward, the bending to some extent as shown in FIG. of its bottom point of a knife.
Move when described main motion device is directed downwards along Z, described cutting knife 6 is put on the closing line of not representing in the drawings.Starting force mainly causes by the stroke that described main motion device 1 surmounts described dead-center position.Thus, the spring 7 that is between cutter supporter 5 and the main motion device 1 is compressed, thereby one is acted on the closing line and cuts closing line through cutting knife 6 corresponding to the power of this spring force.What play a decisive role for described active force is the compression degree of spring, and the latter is subjected to the influence of the speed and the cutter acutance of described main motion device.
Described power or deflection can be measured by a position sensor 8, and this sensor 8 is measured the position of described cutter 6 with respect to dead-center position.Can determine current power by described power characteristic curve then, and for example when departing from the power of expectation, can influence parameter, as cutting speed for next cutting process recomputates.
If the speed of main motion device be lower than a minimum speed and this moment described power surpass a maximum, force, then therefore this blunt sign of cutter 6 especially should change this blunt knife 6.
Fig. 2 represents device by another kind of version with front sectional elevation, wherein, selects spring steel to connect the connection that replaces rotary gemel, so that described knives rack and main motion device are flexibly connected mutually.
