A large amount of not only aspect the driving side and also the controllability aspect the connection between the structure of the base plate 4 of described thorn saw 2 and the shell side that is supported by this base plate 4 make and deviation occurs by rated value adjusting position given in advance with respect to corresponding, this deviation occurs already in the scope of making or by the wearing and tearing or the wrong operation that are caused by operation that described thorn is sawed, the manipulation of this mistake can correspondingly damage described thorn saw.
In order here can to check simply and to calibrate, as shown in Figure 3, be provided with the calibrating installation 33 of calibration holder 49 with calibration plate 34 forms by the present invention, described base plate 4 should arrange with respect to ground, described calibration plate 34 fixed-site and position location, aims at especially mark line 35 of the mark that is arranged on the described calibration plate 34 or rather.Described mark line 35 is about the operation of the reality line corresponding to workpiece side, described instrument under the situation of using thorn saw 2 just its saw blade 8 aim at described line.According to this orientation, described calibration plate 34 is provided with the adaptor 36 that aligns with mark line 35 of projection, these adaptor 36 preferable configuration are the pin 37 that pin 37 especially is configured to classification, and this adaptor 36 is engaged in the described instrument holder 18 when described base plate 4 is placed on the described calibration plate 34, thereby obtain the location of described thorn saw 2 with respect to described calibration plate 34, described location is corresponding to described saw blade 8 active position with respect to workpiece 5 in actual motion, thereby the zero-bit that generation obtains proofreading and correct in the thorn saw that is calibrated.
If described toolroom machine 1 is just being equipped the probe unit of schematically representing by the position of its sensor 30 in addition 28 by the thorn saw 2 of Fig. 1 in the present embodiment extraly in Fig. 2, when being positioned at described thorn saw 2 on the calibration plate 34, just produce the position of mark line 35 in test surface 10 so.If the center line that the longitudinal axis 12 by by the thorn of Fig. 2 saw 2 of described test surface 10 is covered overlaps with described mark line 35, sensing mechanism just especially just obtains affirmation such as the orientation as the correct position of the video camera of sensor 30 uses in the scope of calibration so.Described instrument holder 18 corresponding symbolically illustrate the position that is contained in the instrument in this holder mark can by described signal processing unit 29 and even corresponding servo drive simultaneously to sensor for shooting 30 just the signal chains of video camera check, thereby also can about described instrument 7 just the orientation of saw blade 8 described thorn saw 2 is checked and is regulated, adjust again in case of necessity, wherein just check calibration and implement calibration with pure sensing technology within the scope of the invention in principle, and only actually is just considered mechanical intervention in addition when corresponding mechanical breakdown occurring by software parameter.
Importantly especially combination tool machine 1 especially stings saw and 2 carries out so continuous calibration, utilize described thorn saw 2 also should under the work of difficulty and visual condition, accurately follow the tracks of line 26 and described thorn saw 2 and therefore not only require described instrument 7 accurately to aim at its corresponding zero-bit given in advance, and should in the middle of described line 26, follow the tracks of this line 26.This means, under the visual condition of difficulty, must carry out relevant detection, be used for and correspondingly make instrument 7 aim at the like this detected center of described line 26 in the process that signal is handled by described probe unit 28 profile of line.
In addition, for realizing that this point the present invention also relates to a kind of method and a kind of detection method of the toolroom machine that is used to turn round, in described detection method no matter the vision situation of difficulty and the contrast situation boundary that detects the edge side of described line 26, as explaining the same prerequisite of coming corresponding lines given in advance center with Calculation Method that provides by means of Figure 4 and 5 and by Fig. 6 with 7 block diagram, wherein Fig. 6 and 7 has illustrated the fundamental method flow process in block diagram thus.
Figure 4 and 5 show line 39 different sections in background 40 trend on 41 in other words.By the background 40 of Fig. 4 corresponding to interfering environment with texture, foul, ambiguous profile and analog being arranged for line 39.
Obtain a large amount of contrast transitional regions thus, described contrast transitional region use here as prerequisite such as the camera technique realized by line scan sensor (Zeilensensor) time put 44 as a comparison along scan line 43 accordingly and illustrate.Put as a comparison when described line 39 still has enough contrasts with respect to the edge of background on corresponding scan line 43 and draw, 46 represent described contrast points in other words with 45 at this.
It is right that the contrast points 45 and 46 opposite each other on the edge side of described line 29 that is assigned to scan line 43 forms numerical value thus, and to corresponding numerical value concerning described contrast points 44,45 be in roughly the same spacing to each other along line 39.Under the situation of the trend that keeps described line 39, can determine the average headway of contrast points 44,45 thus along line 39, and also determine the picture centre of described line 39 thus, described instrument just saw blade 8 should be aimed at this picture centre and places in its zero-bit or in its corresponding desired angle position.
For although the interfering structure that has described background also can correspondingly detect described line 39, advantageously, make those not be based on the corresponding contrast between described line 39 and the background and the contrast points 44 that is based on the scrambling of other type conceals.This can reach in the scope by method of the present invention in the following manner, and is just will be in case of necessity given in advance, also can be used as filter criteria by line thickness that described numerical value is determined (contrast points 45,46) by concrete condition.Save the demonstration of the size of the contrast points 44 in the environment that is in described line 39 thus, thereby obtain the background of hypothesis, described line 39 is with respect to clear the displaying of background of this hypothesis.In addition, can exert one's influence such as illumination, gain, white balance to other the parameter that influences contrast.Therefore, can dissolve (ü berblenden) and make it thus actually by unusual bright illumination such as the texture of light color when white balance is inoperative for as the video camera of sensor 30, cannot see.
Although if use the also not outstanding reliably any line of described method, just track identification (Bahnerkennung) does not achieve the goal, that just advantageously cuts off the control function based on track identification, therefore such as automatically making described instrument 7 aim at still unrecognized line 39 given in advance in the machine side in the system of partly independently working.
In pressing the scope of calibration of the present invention, equally can be to checking by method of the present invention, such as checking with respect to 35 patterned background given in advance of the mark line on the calibration plate 34 by means of at least one, described patterned background only just allows the described mark line given in advance 35 of sufficiently clear ground identification at last when having highlighted described mark line 35 by method and it can be discerned concerning described system or rather.The pattern that such inspection also can be arranged on the calibration plate 34 by means of the different modes changing individually in case of necessity carries out.
Fig. 6 has illustrated the operation principle of the thorn saw 2 that can partly independently turn round by the present invention in block diagram, wherein should be with reference to about explanation that Fig. 1 to 5 did and represent servicing unit with 50 once more in ensuing relevant therewith explanation, this servicing unit comprises at this and is used for sensing mechanism 51 and the DPA data processing activity 52 that the actual state to workpiece side detects.As sensing mechanism 51, can perhaps also can as explaining, line scan sensor be set such as the sensor 30 that the video camera form is set as explaining about Fig. 1 about Figure 4 and 5.In the DPA data processing activity 52 that constitutes by computing unit 31 about Fig. 1, obtain handling by described sensing mechanism 51 detected data, and be transfused to selected cell 53 in addition, in described selected cell 53, as long as it is meaningful or be necessary, just in inquiry and assessment part 54, these data are carried out the confidence level inspection, check whether it is fit to draw a conclusion for corresponding target.
At this, especially check that by means of inquiry standard given in advance whether described data are fit to 39 survey ruling, described inquiry standard is represented by the problem area 55 of puing question to unit 56 in Fig. 7.Such inquiry standard especially such as being to belong to the right contrast points of numerical value 45,46 spacing and/or the right position of corresponding contrast points 45,46 each other of different numerical value to each other, makes these contrast points form the trace of the edge side of described line 39.Under the situation of considering these and other inquiry standard, in assessment unit 57, make one's options aspect 39 such as from the contrast points 44 that all is identified, whether being suitable for definite the line at it by means of fuzzy logic.On the basis of the line of so determining 39, under the situation that the contrast points 44 that makes other conceals, the contrast points 45,46 of determining line 39 forms numerical value, and described numerical value has the control of trigger mechanism 60 and the operating unit 61 of adjustment unit 59 and user's side by output shown in Figure 7 58 inputs.To be adjusted to operative orientation as the saw blade 8 that instrument 7 belongs to thorn saw 2 by described trigger mechanism 60, by 61 operation indicatings that on display screen 62, from the reality of work situation, produce of described operating unit for user's demonstration corresponding to line 39.
