Definitions
- the invention relates to a method for calibrating a light section sensor with respect to a member of a robot kinematics that can be controlled by a robot control device and has several members and joints that connect the members to one another in an adjustable manner, the light section sensor being attached to one member.
- the invention also relates to an associated robot system.
- EP 1 931 503 B1 describes a method for determining the position of a virtual tool center point with respect to a known coordinate system of a robot with a robot arm, wherein first the position difference between a feature of a reference component and the virtual tool center point is determined, then the robot arm is moved until the coordinates of the feature of the reference component and the virtual tool center point match, and then the position of the virtual tool center point in the robot coordinate system is determined by determining the robot axis positions for this position of the virtual tool center point.
- the object of the invention is to provide a method for calibrating a light section sensor which can automatically determine a sufficient number of positions from which a transformation matrix can be determined in order to be able to automatically convert position values between a sensor coordinate system of the light section sensor and a reference coordinate system of the robot kinematics.
- the object is achieved by a method for calibrating a light section sensor with respect to a member of a robot kinematics controllable by a robot control device with several members and joints that adjustably connect the members to one another, wherein the light section sensor is attached to one member, comprising the steps:
- Robot systems are used in automated production in order to be able to carry out a large number of different production processes automatically.
- Robot systems consist of at least one robot kinematics, such as a robot arm, which is automatically controlled by a robot control device, i.e. the joint positions of the robot kinematics can be automatically adjusted.
- a robot control device i.e. the joint positions of the robot kinematics can be automatically adjusted.
- weld seams can be created, adhesive beads can be applied, or sealing compounds can be applied to a workpiece via a nozzle guided by the robot kinematics.
- the desired path along which a reference point of a tool guided by the robot kinematics, such as a welding gun tip, a glue nozzle or an application nozzle, is to move automatically can be stored in the robot controller.
- a robot program can call up the stored path in order to use the robot controller to automatically guide the corresponding tool along the desired path by automatically adjusting the joints of the robot kinematics.
- seam tracking comprises an optical sensor that is preferably attached to a flange of the robot kinematics and which, while the tool is moving along the desired path, optically detects a feature of the workpiece associated with the path so that this can be evaluated by the robot control device.
- the feature on the workpiece can, for example, be the joint between two components that are to be joined by means of a weld seam.
- the feature on the workpiece can also be, for example, a groove or an edge on a workpiece along which a bead of adhesive or a bead of sealing is to be applied.
- the optical sensor detects the feature on the workpiece at every moment of the tool's movement along the target path and detects any deviations in the pose of the tool with respect to the feature on the workpiece.
- the robot control device is designed and set up to automatically move the tool guided by the robot kinematics on an actual path that deviates from the target path due to deviations that occur and are detected by the optical sensor. In such a case, the actual path is then modified from the stored target path in accordance with the deviations present in the individual case of a workpiece and the tool is automatically moved accordingly by the robot kinematics.
- the property according to which the robot control device is designed means that the robot control device is constructed in this specific way.
- the property according to which the robot control device is set up means that the robot control device is programmed in this specific way in terms of control technology by means of a program or software.
- a light section sensor usually comprises a laser light source and an optic that expands the generated laser light into a flat fan beam or, using a beam deflection unit, continuously deflects a laser beam within a predetermined angular range in order to repeatedly cover this angular range. This allows an optical line to be projected onto the respective workpiece.
- the projected line can be captured and evaluated by an optical camera.
- the optical camera is usually combined with the laser light source in a common device of the light section sensor.
- the light section sensor as an independent sensor device can be connected to a link in the robot kinematics, in particular a
- the sensor values i.e. the recorded position values of the light section sensor
- the path that the tool is to follow, automatically guided by the robot kinematics, is usually in the form of support points that are available or stored as position values in a robot coordinate system.
- the robot coordinate system can generally be placed anywhere in the robot kinematics.
- a basic robot coordinate system is usually placed in the proximal base member, such as the base frame of the robot kinematics. This means that the position and orientation of the robot coordinate system remains the same in all possible axis positions or poses of the robot kinematics.
- This robot coordinate system can also be referred to as the base coordinate system.
- the light section sensor is generally attached to the last, distal end member of the robot kinematics. This distal end member of the robot kinematics can also be referred to as the flange or tool flange. Since the tool to be handled by the robot kinematics, such as a welding tool, is usually attached there, it is also advisable to attach the light section sensor there.
- Attaching the light section sensor to this member is usually advisable, but the light section sensor can generally also be attached to any other member of the robot kinematics. In both cases, it is also useful to place a separate reference coordinate system in the link to which the light section sensor is attached. is to be or is attached. This reference coordinate system can then also be referred to as a flange coordinate system or a hand coordinate system, depending on the case.
- the reference coordinate system selected in each specific case should be determined in such a way that when the light section sensor is attached, its position and orientation in relation to the sensor coordinate system no longer changes, i.e. it is fixed, even if the joints of the robot kinematics are adjusted, i.e. the robot kinematics are moved.
- the sensor values recorded by the guided light section sensor In order for the sensor values recorded by the guided light section sensor to be correctly evaluated, they must be converted from the sensor coordinate system in which they are present into the specific reference coordinate system. Such a conversion can be carried out using a transformation matrix, for example.
- the transformation matrix depends on the exact position and location (pose) of the light section sensor, i.e. of the sensor device in relation to the member of the robot kinematics to which the light section sensor or the sensor device is attached.
- the light section sensor After the light section sensor has been mounted for the first time on the relevant part of the robot kinematics, the light section sensor must be calibrated with respect to the robot kinematics.
- At least three different positions of the light section sensor must be taken in relation to a calibration object and the corresponding position values must be recorded in each of these positions. From the at least three position values obtained, a transformation matrix can be calculated, which enables a computational transformation between the sensor coordinate system of the light section sensor and the reference coordinate system of the robot kinematics. According to the invention, the detection of such at least three different positions for calibration should be able to take place automatically, so that no manual intervention by a person is necessary.
- the calibration object can be a body of largely any design, provided it has at least a first line feature and a second line feature.
- the first line feature and the second line feature can be formed, for example, by outer edges, inner edges, shoulders, scribe lines, grooves and/or channels on the calibration body.
- the calibration object can be placed on a flat surface of a machining table.
- the machining table can, for example, comprise clamping devices which are designed to hold a workpiece firmly during its machining by the robot system.
- the calibration body itself can be calibrated in its assumed position before the start of the further process steps, i.e. the position and orientation of the calibration body with respect to the robot coordinate system is known to the robot system.
- position and orientation values of the calibration body can be stored in the robot control device of the robot system.
- intersection point of the first line feature and the second line feature is recorded using a teach-in procedure and the position of the intersection point is stored in the robot coordinate system in the robot control device.
- the light section sensor must of course be attached to the link of the robot kinematics before starting the further process steps.
- the light section sensor is moved in particular in a central alignment along the first line feature, automatically controlled by the robot kinematics and the robot control device, in a second direction.
- the second direction is aligned perpendicular to the light fan stretched by the laser light emitted by the light section sensor.
- the light section sensor is moved in this second direction until the projected line of the light section sensor hits the second line feature of the calibration object.
- the current position of the light section sensor is stored in the form of position values in the robot coordinate system as a position in the second direction in the robot control device. This stored second position then forms a second calibration position. This second calibration position is also automatically determined, as is the case with the first calibration position.
- the procedure for automatically determining the third calibration position can essentially correspond to the procedure for automatically determining the first calibration position or the second calibration position, whereby the automatic determination takes place, for example, at a second altitude of the light section sensor that differs from the first altitude.
- the automatic movement of the light section sensor in the first height position along the first path parallel to the first line feature towards the second line feature of the calibration object can be carried out starting from a first starting position which is obtained by the following steps:
- the automatic movement of the light section sensor along the second path parallel to the first line feature towards the second line feature of the calibration object can be carried out starting from a second starting position which is obtained by the following steps:
- the pre-positioning of the light section sensor with respect to the calibration object at a first height with respect to the calibration object by controlled adjustment of the joints of the robot kinematics controlled by the robot control device can be carried out in such a way that a line projected by the light section sensor initially lies outside the first line feature of the calibration object.
- Pre-positioning can be carried out by a person controlling and moving the robot kinematics, for example by means of a robot handheld control device, in such a way that the light section sensor assumes a corresponding position and orientation.
- a main optical axis of the light section sensor can, for example, be aligned perpendicular to the plane of the surface of the processing table and/or perpendicular to a surface of the calibration object.
- the light section sensor projects a line onto the surface of the processing table or, later, onto the surface of the calibration object. The projected line then corresponds to the measuring field or the measuring line along which the optical detection device of the light section sensor can record the reflections of the emitted laser light.
- the light section sensor is now moved parallel to the projected line or in the direction of the projected line automatically towards the calibration object by the robot control device automatically adjusting the joints of the robot kinematics in order to move the guided light section sensor accordingly.
- the height of the light section sensor with respect to the surface of the processing table and/or the calibration object i.e. the distance of the light section sensor in height from the surface of the machining table and/or the calibration object remains constant.
- the automatic movement of the light section sensor along the third path parallel to the first line feature towards the second line feature of the calibration object can be carried out starting from a third starting position which is obtained by the following steps:
- a further altitude which can in particular be a third altitude different from the first altitude and the second altitude, with respect to the calibration object by controlled adjustment of the joints of the robot kinematics controlled by the robot control device such that a line projected by the light section sensor lies outside the first line feature of the calibration object
- the light section sensor is automatically moved at a first height in a first direction parallel to the projected line towards the first line feature of the calibration object until the projected line meets the first line feature of the calibration object.
- the current position of the light section sensor is stored at that moment in the form of position values in the robot coordinate system as a first position in the first direction in the robot control device.
- the light section sensor is automatically moved in the first direction parallel to the projected line over the first line feature of the calibration object, under Maintaining the first elevation until the projected line leaves the first line feature of the calibration object again.
- the current position of the light section sensor is stored at that moment in the form of position values in the robot coordinate system as a second position in the first direction in the robot controller.
- the stored position values of the first position and the stored position values of the second position are both in the robot coordinate system.
- an intermediate position can be determined that lies on a distance between these two positions.
- the intermediate position should preferably lie near the planned working point of the tool.
- the working point can be, for example, a center point of a welding gun tip, an adhesive nozzle or an application nozzle.
- the intermediate position is stored as a first calibration position in the first direction in the robot control device.
- the automatic determination of the first intermediate position in the first direction, which lies between the stored first position and the stored second position can be carried out by determining as the first intermediate position the point which lies halfway along the path which the light section sensor travels in the first direction when the light section sensor moves from the first position to the second position, and/or the automatic determination of the second intermediate position in the first direction, which lies between the stored first Position and the stored second position can be achieved by determining as the second intermediate position the point which lies halfway along the distance that the light section sensor travels in the first direction when the light section sensor moves from the third position to the fourth position, and/or the automatic determination of the third intermediate position in the first direction, which lies between the stored fifth position and the stored sixth position, can be achieved by determining as the third intermediate position the point which lies halfway along the distance that the light section sensor travels in the first direction when the light section sensor moves from the fifth position to the sixth position.
- the automatic determination of the first intermediate position in the first direction, which lies between the stored first position and the stored second position can be carried out by determining as the first intermediate position the point which, when the light section sensor moves from the first position to the second position, lies on a route point which deviates from half the route which the light section sensor travels in the first direction
- the automatic determination of the second intermediate position in the first direction, which lies between the stored third position and the stored fourth position can be carried out by determining as the second intermediate position the point which, when the light section sensor moves from the third position to the fourth position, lies on a route point which deviates from half the route which the light section sensor travels in the first direction
- the automatic determination the third intermediate position in the first direction, which lies between the stored fifth position and the stored sixth position can be achieved by determining as the third intermediate position the point which, when the light section sensor moves from the fifth position to the sixth position, lies on a route point deviating from the halfway point which the light section sensor travels in the first direction
- a supplementary fourth calibration position or an alternative further calibration position can be obtained automatically by the further step:
- a mathematical transformation matrix can be automatically determined which is designed for automatic, computational transformation between a sensor coordinate system of the light section sensor and a reference coordinate system, in particular a flange coordinate system or a hand coordinate system, of the robot kinematics.
- an intersection point of the first line feature and the second line feature can be recorded by means of a teach-in method and stored in the robot control device.
- the first line feature of the calibration object intersects the second line feature of the calibration object at the intersection point.
- the intersection point can be formed, for example, by a corner of the cuboid.
- the intersection point can also be another outer edge, inner edge or inner corner of a calibration body.
- a cuboid with a known length, width and height stored in the robot control device can be used as the calibration object, wherein a first edge of the cuboid forms the first line feature and a second edge of the cuboid, which abuts the same corner of the cuboid as the first edge, forms the second line feature.
