Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the present invention relates to a kind of calibration steps of automatic cutting machines, and its flow process is as shown in Figure 1, specific as follows:
Step 101, after automatic cutting machines controls conveyer belt transmission predeterminable range, utilizes the mark on data read module reading conveyer belt.
Specifically, in present embodiment, the conveyer belt of automatic cutting machines is provided with mark, and this mark correspondence lays the origin position in platform coordinate system.It should be noted that, laying platform and Cutting table are provided with virtual coordinate system, are respectively and lay platform coordinate system and Cutting table coordinate system.In the present embodiment, the initial point of summit, the lower left corner as coordinate system of laying platform and Cutting table is set respectively.In actual applications, origin position also can sets itself as required, as summit, the lower right corner at table top etc.
Also it should be noted that, conveyer belt transmit predeterminable range for preset transmitting range be automatic cutting machines in operation process, the distance that conveyer belt transmits at every turn, the table as being Cutting table is long.
It is worth mentioning that, the data read module in present embodiment can be image acquisition device, and this image acquisition device can be arranged on the head of automatic cutting machines, can gather the image of whole Cutting table table top.Specifically, the color of mark and the color of conveyer belt can be different, better, mark can adopt the colour code presented a contrast with conveyer belt color, in particular, in present embodiment, yellow mark can be used, because yellow is comparatively eye-catching, be also more conducive to follow-up image procossing, in addition, except yellow can also adopt redness, blueness, green, orange etc.In present embodiment, image acquisition device can get the image of the conveyer belt comprising yellow mark.
Step 102, determines to be identified at coordinate corresponding in Cutting table coordinate system.
Specifically, in this step, a processing module can be utilized, process according to the data that data read module reads, and determine that this is identified at the point coordinate in Cutting table coordinate system.Such as, in actual applications, image acquisition device can be utilized to carry out IMAQ to the conveyer belt comprising mark, in general the full court face carrying out comprising Cutting table is needed to gather, above Cutting table table top, collection can be overlooked to table top, and the view data collected is passed to processing module.
Furthermore, processing module carries out feature extraction and process to view data by colour recognition, as extracted the yl moiety in image, carrying out and the color of identification standard image, size contrast, confirming the position identified, namely coordinate.Certainly, processing module can also carry out the process such as removal noise, enhancing, recovery, segmentation, extraction feature to image, obtains the coordinate of mark more accurately.
It is worth mentioning that, data read module in present embodiment can utilize various kinds of sensors to realize, if sensor is metal detector, correspondingly, be designated metal label, that is, what post in advance on a moving belt is metal label, when being sent to Cutting table, metal detector is utilized to detect the accurate location of metal label.Because metal label cost is lower, it is convenient to realize, and effectively can reduce the hard-wired cost of calibration function.In addition, in actual applications, mark can also utilize RFID label tag, and correspondingly, sensor can be RFID identifier, because RFID recognition technology antijamming capability is better, when detecting, reliability and precision higher, also make the automatic cutting machines in present embodiment can need design different mark and sensor according to different application, meet the demand of the different occasion of user flexible and changeablely, thus ensure that this practicality invention can possess application scenarios widely.In addition, this step also can utilize other existing device to realize, and will not enumerate at this.
Can also illustrate, in actual applications, data read module can also be signal receiver, and mark can also correspond to signal projector.Utilize the signal that signal receiver Received signal strength transmitter sends, thus identify mark, further increase the precision of identification.
In addition, much may be used in addition reading the technological means that conveyer belt identifies, will not enumerate at this.
Step 103, judges that whether this coordinate points is the initial point of Cutting table coordinate system; If so, then step 106 is performed; If not, then step 104 is performed.
The present inventor finds, only need, by two virtual coordinate system alignment, utilize initial point to the distance determination material of initial point from laying the translation position of platform to Cutting table, the distance that the conveyer belt also just can calibrating automatic cutting machines rotates at every turn.
Specifically, utilize identification point coordinate corresponding respectively in two coordinate systems to contrast, during owing to being identified at original position, corresponding is the known coordinate position (what utilize in present embodiment is origin) of laying platform coordinate system, when being identified at stop position, the coordinate position of corresponding is Cutting table coordinate system, after calibration, mark should stop at the origin of Cutting table coordinate system, so by comparing the coordinate of stop position and origin, can judge whether to need fine setting to calibrate.
Step 104, coordinates computed point is to the direction of Cutting table coordinate origin and distance.
Specifically, the coordinate points that processing module can be utilized to calculate confirm in step 102 is to the actual range of the Cutting table origin of coordinates and direction.
For example, in actual alignment, the distance of possible conveyer belt movement is not the length needed for reality, the position so identifying stopping may not be just the origin of coordinates of Cutting table, now, if displacement is too short, the position that mark stops may just in the positive direction position of the origin of coordinates, if displacement is long, the position that mark stops may just in the negative direction position of the origin of coordinates.
It is worth mentioning that, can be utilize the operation program in processing module to realize the calculating between coordinate points in this step.
Step 105, automatic cutting machines moves according to direction and distance controlling conveyer belt, until the origin position in the corresponding Cutting table coordinate system of the coordinate position of mark correspondence.
Specifically, automatic cutting machines, according to the direction and the distance that calculate gained in step 104, controls conveyer belt and moves, identify the origin position that namely can correspond in Cutting table coordinate system.If also unjustified, step 104 can be repeated to step 105, until the coordinate points at mark place is exactly Cutting table coordinate origin.
Step 106, the shift length of record identification, as conveyer belt transmitting range next time.
Specifically, shift length is the distance from laying the origin position of platform and be displaced to the origin position of Cutting table, after calibration, arranges the distance that conveyer belt transmits at every turn and is this shift length, can determine the accuracy transmitted.
Below for Fig. 2 a, Fig. 2 b and Fig. 2 c, illustrate: (in figure, 21 for laying platform, and O point is for laying platform coordinate origin, and the distance that OP is 2 is long for laying table; 22 is Cutting table, and Q point is Cutting table coordinate origin, and the distance that OQ is 2 is that cutting table is long; The default transmitting range of conveyer belt is the long A of cutting table.)
If as shown in Figure 2 b, if detect that mark stop position is B1 in the distance of S1, QS1, the direction and the distance that calculate gained are at step 104 that the B1 of positive direction, so identifies actual displaced position S=A+B1.
If as shown in Figure 2 c, if detect that mark stop position is B2 in the distance of S2, QS2, the direction and the distance that calculate gained are at step 104 that the B2 of negative direction, so identifies actual displaced position S=A-B2.
It should be noted that, in the application of present embodiment, if only need calibration once, after so having calibrated, mark also can be eliminated, and makes after primary calibration flow process, the conveyer belt running after mark can not affect.Carry out primary calibration after each automatic cutting machines installs as arranged, or carry out primary calibration after each automatic cutting machines start.
Present embodiment in terms of existing technologies, the main distinction and effect are: utilize the mark that conveyer belt is preset, after conveyer belt rotates predeterminable range, follow conveyer belt and be sent to Cutting table from laying platform, recycling data read module reads mark on conveyer belt, thus determine the relation of this home position and Cutting table origin of coordinates position, moved by control conveyer belt and finely tune, mark is made finally to stop at the origin position of Cutting table, then the actual displacement distance of mark is recorded, the rotation distance making conveyer belt each is and is identified at the ongoing actual displacement distance of calibration.Calibration steps in present embodiment achieves automatic cutting machines automatically can carry out Crop Area and lay the initial point in district and calibrate in debug process, improve calibration accuracy and efficiency, reduce the delivering position mistake due to conveyer belt, the material cutting mistake on the Cutting table caused.
Present embodiment can also be optimized further, and sensor, except identifying at the parallel angle detecting long with table, can also utilize vertical both direction jointly to detect mark, detects the position S3 identifying and stop at as shown in Figure 2 d.That is, sensor is utilized to detect, until sensor detects the position of mark along the X-direction of Cutting table and/or Y direction; Wherein, X-direction is vertical with Y direction.Correspondingly, when controlling conveyer belt and moving, be control conveyer belt to move along the X-direction of Cutting table and/or Y direction, until the position of mark overlaps with the origin position of Cutting table.Further limit sensor can detect in the X-direction of level and/or Y direction, makes full use of virtual coordinate system and carries out position control, reaches the object of the shift position accurately controlling mark.It is worth mentioning that, sensor is needed to move in the two-dimensional direction detection, the support installed in addition can be utilized, also the support of head itself can be utilized, because head on automatic cutting machines inherently has the support of X-direction and Y direction, utilize existing hardware equipment effectively can also reduce hardware cost, be convenient to promote.
When recording shift length, just not only to record direction and the distance of S3 and Q point-to-point transmission X-axis, also will record direction and the distance of S and Q point-to-point transmission Y-axis.Certainly, if QO direction is X-direction, QR direction is Y direction, and so Y direction has the installation site of skew explanation conveyer belt to have error, can rely on and the adjustment of conveyer belt has been come, the distance of the actual movement of conveyer belt still only with the distance dependent of X-direction.
It is worth mentioning that, present embodiment, after the shift length of record identification, can also comprise the step removing mark.Make after primary calibration flow process, the conveyer belt running after mark can not affect.Also it should be noted that, the mark in present embodiment can utilize tape-stripping on conveyer belt, utilizes adhesive tape constant mark, simply firmly.
