Definitions
- the invention has for its object to provide an electrical monitoring circuit, which can be used.
- FIG. 1 shows a block diagram of the diagnostic device according to the invention.
- FIG. 2 shows a block diagram for a device designed according to the invention for predictive diagnosis of the current quality of the welding spots of a spot welding robot
- Processing, processing or conversion of solid, liquid gene and / or gaseous starting materials for a modified or new product is considered as a technical system 1, in which a device for quality diagnosis according to the invention can be used.
- the predictive diagnostic device initially has a device 2 which is used to record sets of measured values from the technical installation 1.
- a device 2 which is used to record sets of measured values from the technical installation 1.
- current measured values e.g. of equipment and substances in the system, whose current values influence the desired quality of the technical work result at the output of technical system 1.
- the measured value records which are usually recorded cyclically and at time-discretely predetermined times, are supplied on the one hand to a system model 12 and on the other hand to a device 3 which serves at least to parameterize the system model 12.
- the system model 12 permanently creates an actual value for the current quality of the technical work result of the technical system 1 from the current sets of measured values of the technical system 1, which are preferably available cyclically.
- This actual quality value at the output of the system model 12 can be used in a variety of ways.
- the actual quality value is compared in a comparator 13 with a predetermined quality target value 14. Any quality deviation that may result from this can advantageously be fed to an additional processing unit 15.
- This can trigger reporting actions 23 which signal the current quality deviation, for example to the operating personnel of the system.
- the current values of the quality deviation are fed to a regulation or control 24 in a direct or adapted form. From this, this can in turn derive control signals 25 intended for the technical installation 1. ten, whereby their resources can be adjusted so that the current quality actual value at the output of the system model 1 is adapted as quickly as possible to the specified quality setpoint and thus a quality deviation is as close to zero as possible.
- Figure 1 is represented by a dashed arrow provided with the reference numeral 22.
- the selected sets of measured values are fed to a so-called database 8.
- the selection of the measured value sets from the stream of the measured values made available online by the measured value acquisition 2 takes place on the condition that the current characteristic value for the moment a selectable measured value set occurs
- Quality of the respective work result of the technical system can be recorded.
- This can e.g. in that a work result of the technical system corresponding to a selected set of measured values, e.g. a workpiece from a production system, taken and e.g. is analyzed by means of a laboratory test.
- the characteristic values 4 which are obtained as the examination result and which represent a measure of the respective quality of the technical work result of the technical installation 1 are likewise fed to the database 8 via a possible intermediate storage in a memory 5. In the example in FIG. 3, this is represented by a connection provided with reference number 11.
- the selected sets of measured values and the associated quality parameters are stored in groups 8 in database 8.
- an evaluation device 9 by successive evaluation of the measured value sets 2 and the associated quality parameters through an iterative optimization at least the parameters of the system model generated and / or optimized.
- the device 3 for parameterizing the system model 12 is advantageously constructed in the form of a neural network. If appropriate, the device 9 can also be designed such that the logical structure of the system model is also generated by, for example, iteratively evaluating the individual groups of related sets of measured values and quality parameters.
- FIG. 2 schematically shows a device designed according to the invention for predictive diagnosis of the current quality of the welding spots of a spot welding robot.
- the spot welding device is an example of a technical system 1, the work results, i.e. the quality of their welding spots can be determined with the aid of the diagnostic device according to the invention.
- the system preferably contains at least one automatic handling device 16, which is used to position welding guns 17. In this way, welding points are introduced in a program-controlled manner on an exemplary, sheet-like weld metal 18.
- the technological parameters e.g. the lens diameter of the welding spots and the color distribution on their surface serve e.g. in the levels dark, medium and light gray.
- the technological quality of spot welds can be assigned to the classes "good, sufficient, poor and insufficient".
- the technical system in turn includes a device 2 for recording sets of measured values, the current values of which influence the desired quality of the welding spots of the spot welding robot.
- the measured value sets contain at least current values of the
- the identifier x in the designations Plx and P2x should express that the measured values are recorded cyclically at preferably equidistant times tx. As a result, chains of values per measurement parameter occur over a longer period of time, ie for each of the times tl, t2, t3 ... tx, for example a measured value Pll, P12, P13 ... Plx for the welding current and, for example, a measured value P21, P22, P23 ... P2x for clamp pressure.
- These measured value sets, which are recorded online, are supplied via the data line 22 to the device 3, which is used to generate and parameterize the system model 12, and, on the other hand, to the system model 12 itself via the data line 26.
- the device 3 for generating and parameterizing the system model 12 in FIG. 2 in turn has a database 8, which is used to store sets of measured values 2 and associated characteristic values, which is a measure of the respective quality of the welding spots 19 of the spot welding robot 16 , 17 are.
- a database 8 which is used to store sets of measured values 2 and associated characteristic values, which is a measure of the respective quality of the welding spots 19 of the spot welding robot 16 , 17 are.
- the database there is a complete set of the measured values Plx, P2x for each acquisition time tl, t2, t3 ... tx
- the technological parameters influencing the quality of welding spots are the welding current Plx, the clamp pressure P2x, a so-called lead time P3x for the increase in the welding current, a so-called current time P4x for the duration of the constant value of the welding current and a so-called hold time P5x for the drop in the welding current is recorded as measured values.
- a complete set of these measured values ie Pll, P21, P31, P41, P51, Plx, P2x, P3x, P4x, P5x, are common in the data base for each acquisition time tl, t2, t3 ...
- the quality parameters belonging to a measured value set can be determined, for example, by a test person located in the vicinity of the spot welding robot, or by an automatic test device, for example provided with a video camera with an attached evaluation device, or by a so-called unbuttoning of sample weld spots as part of a destructive workpiece test in a laboratory. In the example in FIG. 2, the quality parameters are entered into the database 3 via the data line 11.
- a subsequent evaluation unit 9 By successively evaluating the measured value sets available in the database and the associated quality parameters, in a subsequent evaluation unit 9 in a so-called “offline” method, ie not in time with the preferably cyclical online acquisition of the measured value sets, at least the parameters of the Depending on the performance of the algorithm used in the iteration or the structure of the system model, it may also be possible that the structure of the system model itself is also optimized and adaptively adapted to changes in the measured value sets a so-called neural network, or evolution strategies or so-called cluster processes can be used for iteration.
- the determined parameters are fed to the system model 12 via the data line 10. This is now able, as it were, in the form of an online converter from the current ones supplied cyclically via the data line 26
- the system model can be regarded as a corresponding n-dimensional value structure.
- a structure is shown by way of example for an arrangement having four measured values Pl ... P4.
- this structure there is a range of values for the actual quality value Qm. These are marked in FIG. 2 by oblique hatching. So e.g. 21 a so-called “critical area”, in which measured value sets therein are assigned quality characteristics with undesired values after prediction by the system model.
- Spot welding robots contain 16 characteristic values.
- the measured value of the gun pressure P2x of the spot welding robot is advantageously simulated by detecting the air pressure in a pneumatic drive of the guns.
- the quality of welding spots is particularly influenced by values which characterize the course of the welding current of the spot welding robot. It is therefore advantageous if the measured value sets characterize values for the so-called “lead time” in the course of the welding current, ie the rise time of the current, for the so-called “current time” in the Course of the welding current, ie the phase of constant and maximum welding current, and included in the course of the welding current for the so-called “hold-up time”.
- the quality of welding spots is particularly influenced by values which characterize the temperature profiles occurring during the spot welding process. It is therefore advantageous if the measured value sets additionally contain characteristic values for a temperature of a coolant of the welding caps on the tongs of the spot welding robot. Finally, a flow and / or return temperature of a coolant for welding caps on the pliers of the spot welding robot (16), characteristic values can allow conclusions to be drawn about the current quality of the current technical work result.
