Definitions
- the invention relates to a device for positioning a tool relative to a workpiece according to the preamble of patent claim 1.
- Such a device is for example from the
- EP 0 859 681 B1 known.
- drives are provided which enable a relative movement along the three Cartesian spatial axes. This document says nothing about the control of the drives.
- stepper motors In machine tools, it is common to control the drives for the individual spatial axes via stepper motors, increments of the stepper motors then being counted, which is a measure of the position. For precise processing But then an extremely precise clamping of the workpiece is also required.
- An important area of application of the invention is the application of pieces of material to a workpiece.
- Pieces of material in the sense of the present invention can be pieces of any material which are in solid or liquid form. These can be solderable materials, such as gold, copper, tin, glass or plastic, which are in particular in the form of micro-material pieces in the form of solder balls, glass balls or plastic balls. It can also be ceramic pieces and components, such as Miniature circuits, SMD components or the like. In general, any material can be applied with the invention.
- the object of the invention is therefore to improve the device in such a way that the workload for clamping the workpieces is reduced and nevertheless the required
- the basic principle of the invention is to control the relative positioning via cameras.
- the precision the clamping of the workpieces then has no influence on the working accuracy, since the positioning of the tool is controlled by cameras that orient themselves on the workpiece, in particular on its edges.
- Fig. 1 is a schematic diagram of a device according to the
- Figure 2 is a schematic diagram according to a second embodiment of the invention.
- FIG. 3 shows a schematic diagram of a third exemplary embodiment of the invention
- FIG. 4 is a schematic image seen from the camera mounted in the y direction and after the tool is positioned in the x and z directions; and FIG. 5 shows an image of the second camera, on the basis of which the tool is positioned in the Y direction.
- FIGS. 1-5 relate to the application of solder balls, it should be expressly pointed out that any positioning of a tool relative to a workpiece is possible with the invention and that, for example, the application of pieces of material as defined in the introduction can also be carried out and also the removal of pieces of material, such as Soldering of an object.
- this is a relative displacement, ie the drives 2, 3 and 4 can also be assigned to a cross table, not shown, on which the workpiece 6 is clamped.
- the solder is fed to the workpiece and melted there in a known manner by a laser pulse.
- the workpiece 6 here has two mutually perpendicular surfaces 7 and 8, the workpiece being clamped so that the cutting line of the two surfaces 7 and 8 lies exactly in one axis, here the y-axis.
- the surfaces 7 and 8 are each at an angle of 45 ° to the x, y plane.
- Tip 5 of the capillary is positioned at predetermined locations 9 of the workpiece 6 so that a solder ball is applied there and a "bumper" is soldered on.
- two cameras 10 and 11 are provided, the images of which are evaluated by a control unit 12, from which
- a camera here the camera 10, is essentially aligned in the y-axis.
- the relative position between the tip 5 of the capillary 1 and the workpiece 6 with respect to the x, z plane is therefore detected with it.
- the images from the cameras are processed via edge detection.
- the camera 10 thus essentially captures an image of the two edges 13 and 14 of the surfaces 7 and 8 facing it and the tip 5 of the capillary 1.
- the second camera 11 is positioned so that it is oriented perpendicular to a surface 8 of the workpiece. It is used to monitor the relative position between the capillary and the workpiece with respect to the y-axis and to control the drive 3 for this axis.
- the image evaluation here can evaluate the edge 14 of the surface 8 or also the contour of the point 9 at which the solder is applied shall be .
- the workpiece 6 is so long in the y direction that it would collide with the camera 10.
- the camera 10 is therefore oriented at an angle ⁇ with respect to the y axis, the workpiece 6 and not the capillary 1 being moved in the y direction here.
- the camera 10 detects the edges 13 'and 14' of the surfaces 7 and 8 and the position of the tip 5 with respect to the x, z plane.
- the camera 11 is again aligned in the same way as in the embodiment of Fig. 1, i.e. perpendicular to the surface 8 of the workpiece 6.
- a plurality of workpieces 6, 6 'etc. are lined up in succession along the y-axis, the workpieces also being moved at least along the y-axis when the capillary 1 is stationary. Since a camera positioned in the y-axis would also collide with the workpieces here, it is provided that a mirror 15 can be moved between the successive workpieces 6 and 6 ', this mirror here by 45 ° with respect to the x, y plane is tilted. The camera is then aligned parallel to the z-axis and transmits an image to the controller 12 that corresponds to the image that would be taken directly in the y-axis. The mirror 15 can be moved via an arm 16 and a drive 17 at least parallel to the z-axis so that individual workpieces can pass beneath it. As soon as the next workpiece is waiting for processing, the mirror 15 is then moved down again in the z direction.
- the camera 11 is in turn positioned perpendicular to the plane 8 of the workpiece 6.
- FIG. 4 schematically shows the image "seen” by the camera 10 with the tool 1, the workpiece 6 in the form of two Conductor plates 7 and 8 and the edges 13 and 14, on which the image evaluation and control are based.
- So-called pads 16 and 17 can also be applied to the workpiece, which in turn have sharp edges on which the image evaluation can be oriented. These pads are arranged in a predefined position to the solder point.
- the tool 1 can be positioned in the z and x directions.
- FIG. 5 shows an image that is seen by the camera 11, which carries out the positioning on the basis of the edges or the pads in the y direction.
