As can be seen from fig. 1, the positioning plate 2 has a flat upper inclined surface, and can stably place the printing material 21; and be provided with the locating plate 6 at locating plate 2's side, when printing material 21 side and locating plate 6 support and hold, printing material 21 just can have stable reference, is convenient for follow-up high accuracy overlap cut.
The turning plate 3 is rotatably disposed on the frame 1 and opposite to the positioning plate 2, and referring to fig. 1 and 2, the printing material 21 is turned over by rotation and is stably placed on the upper inclined surface of the positioning plate 2. In other words, as the incoming material may be right side up or reverse side up, different placement modes are selected according to different sleeving and cutting modes; namely, if the front side cutting mode is selected, the front side upward incoming material is directly placed on the positioning plate 2, and when the reverse side incoming material is placed on the turning plate 3, the reverse side is rotated through the turning plate 3, and meanwhile, the turned printing material 21 is placed on the positioning plate 2, so that the front side cutting is realized. Of course, the manner of selecting the back side cut-over may also refer to the above process, and will not be described herein.
Since the mark points 22 are located on the front surface of the printing material 21, the manner of determining the position information of the mark points 22 is different for different overprinting manners. When the front surface is sheathed and cut, the point can be automatically scanned by a CCD camera of the numerical control cutting machine directly, so that the cutting table surface 23 is moved after the cutting is finished according to the cutting pattern output by definition according to the control software of the numerical control cutting machine.

The camera 19 synchronizes the position information to the control software of the numerical control cutting machine, and the numerical control cutting machine rotates and moves the cutting pattern according to the position information to obtain an accurate cutting image.
The conveying component 5 is located on the frame 1 below the locating plate 2, so that the function of determining the reference position of the printing material 21 can be achieved, the printing material 21 can be driven to move towards the locating baffle 6, and when the printing material 21 reaches the locating baffle 6, the conveying component 5 stops moving, so that the printing material 21 is ensured to be located at a stable reference position.

And a conveying component 5 is arranged on the frame 1 at the lower side of the positioning plate 2, and can automatically convey the overturned printing material 21 to the positioning baffle 6, so as to determine the reference position of the printing material 21.

Wherein the camera 19 is a USB camera.
Referring to fig. 3, a control motor 12 is disposed on the fixing plate 11, and the control motor 12 may be a servo motor or a stepper motor, and precise control is implemented through a PLC, so that the movement parameters of the camera 19 can be precisely recorded. The control motor 12 is connected with the end of the screw rod 17 through the synchronous belt gear train 13 and is used for driving the screw rod 17 to rotate, and the screw rod 17 is rotatably arranged on the fixed plate 11 through mounting seats 18 at two ends of the screw rod 17.

The conveying assembly 5 of the present application takes a conveying belt as an example, and the conveying belt is horizontally arranged as a whole, so that the printing material 21 can move horizontally on the conveying assembly 5 and always keeps a horizontal state. On this basis, the belt surface of the conveyor belt is disposed perpendicularly to the inclined surface of the positioning plate 2, thereby ensuring the conveyance stability of the printing material 21. Of course, the conveying assembly 5 includes, but is not limited to, this manner, and other conveying manners with horizontal movement may be adopted, so long as a stable conveying manner is ensured.
In addition, in order to ensure that the printed material 21 has a stable reference, the positioning baffle 6 has a vertical blocking surface, and can be abutted against the side edge of the printed material 21, so that the lower side edge of the printed material 21 is horizontal in cooperation with the conveyor belt, and the left side edge and the right side edge are positioned in a vertical plane, so that the printed material 21 has a stable reference. It should be noted that, the above-mentioned reference references are provided to provide stable recording parameters for the camera 19, so as to improve the accuracy of the deviation parameters of the mark points 22 and the cut through hole pieces, so as to achieve the purpose of precise cutting.

The frame 1 is provided with a control cylinder 4, and the power end of the control cylinder 4 is hinged with the turning plate 3 and is used for controlling the turning plate 3 to rotate. The control cylinder 4 can be precisely controlled by a PLC, so that the control precision of the turning plate 3 is improved.
It should be noted that, the present application uses the datum plate cut through by the mark point 22 to map and calibrate the position of the locating plate 2 and the position on the numerical control cutting machine, thereby establishing a reference datum under the same coordinate system;
The mapping calibration comprises the following steps:
Placing a reference plate on a cutting table 23 of a numerical control cutting machine, automatically scanning the cutting holes by a CCD camera of the numerical control cutting machine by taking a coordinate system xoy as a reference, and accurately reading the coordinates of the three cutting holes and the coordinates of a grabbing point V on the cutting table 23, as shown in FIG. 5;
the robot 24 is adopted to grasp the V point on the reference plate and put on the positioning plate 2, and at the moment, the positioning plate 2 is provided with a positioning surface taking the coordinate system xoy as a reference and the coordinate of the grasping point W on the positioning plate 2;
When the printing material 21 is placed on the positioning plate 2, two adjacent right-angle sides of the printing material 21 coincide with the x-axis and the y-axis of the coordinate system xoy, the robot 24 accurately grips the printing material 21 with the coordinates of the V-point (the coordinates of the V-point are the same as those of the W-point), and places the printing material 21 on the cutting table 23, and the printing material 21 is referenced to the coordinate system xoy on the cutting table 23. It should be noted that, since the printing material 21 on the positioning plate 2 and the printing material 21 on the cutting table 23 are located in the same reference coordinate system, precise gripping and positioning can be achieved in the case of coordinate determination.
On the basis of the embodiment, the numerical control cutting machine corrects the discharge graph according to the position deviation and the deviation angle calculated by the sampling signals and outputs a cutting graph to obtain an accurate cutting image, so that high-precision cutting is performed.
In summary, in the embodiment, the reference plate with the cut end of the marking point 22 is used to map and calibrate the position of the positioning plate 2 and the position of the numerical control cutting machine, so as to establish the reference standard under the same coordinate system. On the basis, the coordinate system is established by taking two adjacent right-angle sides of the reference plate as an x axis and a y axis, when the reference plate is positioned on a cutting table 23 of the numerical control cutting machine, control software can take the coordinate system xoy as a reference standard, and when the reference plate is transferred to the positioning plate 2 through the ultra-high precision robot 24, the positioning plate 2 can also take the coordinate system xoy as a reference standard, so that synchronous mapping calibration is realized.
When the positioning plate 2 is referenced to the coordinate system xoy, two adjacent right-angle sides of the printing material 21 need to coincide with the x-axis and the y-axis of the coordinate system xoy, so as to ensure that the printing material 21 can be referenced to the coordinate system. Simultaneously, three high-precision cameras 19 are arranged on the positioning plate 2, and the position deviation of the mark points 22 on the printing material 21 relative to the cut-through holes and the deviation angle of the connecting line between the two mark points 22 relative to the connecting line between the two cut-through holes are read through the cameras 19; the position information of the cut-through hole is determined by a CCD camera, namely, the CCD camera can determine the position coordinates of the cut-through hole when the reference plate is positioned on the cutting table-board 23.
When the printing material 21 is grasped and placed on the cutting table 23 of the numerical control cutting machine by the high-precision control of the same robot 24, the printing material 21 can naturally be positioned in the coordinate system xoy of the cutting table 23 and is referenced with the coordinate system. On the basis, the numerical control cutting machine corrects the discharge graph according to the position deviation and the deviation angle calculated by the sampling signals and outputs a cutting graph, the working procedures of cutting, indentation, slotting and the like are automatically completed, and the cutting table surface 23 is moved after completion.
It should be noted that, the positioning board 2 of the present application actually determines the reference standard of the printing material 21, and determines the coordinate system xoy of the reference board and the position coordinates of the cutting holes and the grabbing points through the reference board under the high-precision reading calibration of the CCD camera, so as to synchronously map and calibrate to the positioning board 2. In addition, the cutting through holes are hollow round holes, and the grabbing points W and the grabbing points V on the numerical control cutting machine are obtained through a teaching mode of the cooperative robot 24, namely, fine cutting, reading and calibrating by means of a CCD camera on the numerical control cutting machine.
And the present application establishes three sub-coordinate systems x 1o1y1、x2o2y2、x3o3y3 in the coordinate system xoy by using the centers of the three cut-through holes on the reference plate as the origin, refer to fig. 7. The origin of the three sub-coordinate systems in coordinate system xoy is labeled o1(lx1,ly1),o2(lx2,ly2),o3(lx3,ly3); because the marking points 22 of different batches may be different from the three cut-through holes, the three marking points 22 in the three sub-coordinate systems are labeled P1'(px1,py1),P2'(px2,py2),P3'(px3,py3); here, that is, P 1'、P2'、P3' is the positional deviation with respect to the three cut-through holes. Of course, the recording of the positional deviation of the coordinates is achieved by the high-precision camera 19.
o1(lx1,ly1),o2(lx2,ly2),o3(lx3,ly3) Can be obtained by manual measurement or direct reading by the camera 19, so that the origin deviation P1(lx1+px1,ly1+py1)、P2(lx2+px2,ly2+py2)、P3(lx3+px3,ly3+py3). of the three marker points 22 from the origin of the coordinate system xoy and the values of px 1,py1,px2,py2,px3,py3 can be read by the camera 19. Thereby determining the offset coordinates of the three marker points 22.
On this basis, the value of the deviation angle θ can be calculated in the coordinate system xoy, i.e., tan θ= (k2—k1)/(1+k1×k2); where k1 is the slope of line o 1o2 and k2 is the slope of line P 1P2. The slope of o 1o3 or o 2o3 can be calculated in the mode, and any slope can be selected according to different requirements to calculate the angle required to rotate, so that the cutting track is corrected, and a cutting image of an accurate point is obtained.
In addition, the number of cameras 19 is three, the pixels of the cameras 19 are 2592×1960 or larger than the parameter at the positions corresponding to the three cut-through holes respectively, the window length of the cameras 19 is 13mm, and each pixel is 13/2592=0.0050 mm. The camera 19 window herein refers to a window area that each camera 19 can capture.
It should be noted that, because the positions of the marking points 22 of the printing materials 21 of different batches may be greatly different, three positional relationships exist between the acquisition window of the camera 19 and the marking points 22 and the cut-through holes, specifically as follows:
Firstly, the marking point 22 and the cut-through hole are simultaneously positioned in the acquisition window, and the camera 19 can directly read the position coordinates of the marking point 22 and the position deviation of the marking point 22 and the cut-through hole, so that the detection of the position deviation and the deviation angle of the marking point 22 is finished by the characteristics;
Secondly, in the initial state, the cut-through hole is positioned in the acquisition window, the mark point 22 is not positioned in the acquisition window, at the moment, the camera 19 can be moved, the mark point 22 and the cut-through hole are simultaneously positioned in the acquisition window, the position coordinates and the position deviation are read, and the detection of the position deviation and the deviation angle is completed;
Third, the cut-through hole is located in the collection window, the mark point 22 is not located in the collection window, and only the mark point 22 is located in the collection window after the camera 19 is moved, the deviation coordinate (P ' x 1,p'y1) of the camera 19 relative to the cut-through hole after the movement and the deviation coordinate (P ' x 1',p'y1 ') of the mark point 22 relative to the camera 19 read by the camera 19 are recorded, then the coordinate of the mark point 22 in the sub-coordinate system is P 1'(p'x1+p'x1',p'y1+p'y1 '), and the coordinate of the mark point 22 in the coordinate system xoy is P 1(lx1+p'x1+p'x1',ly1+p'y1+p'y1 '), so as to determine the deviation coordinate and the deviation angle of the mark point 22 in the coordinate system xoy.
Referring to fig. 6, the method further includes:
Placing the printed material 21 on the positioning plate 2 with the front side facing upwards, so that two adjacent right-angle sides of the printed material 21 coincide with the x-axis and the y-axis of the coordinate system xoy;
The printed material 21 is grasped and placed on a numerically controlled cutter by a robot 24, and the CCD automatically scans the marking points 22, and the software outputs a cutting pattern cut by definition, which will not be described in detail here.
It should be emphasized that, in the present application, two rectangular plane systems are established by using the reference plate, the coordinate system data on the cutting table 23 is mapped into the coordinate system of the positioning plate 2, and the synchronous movement of the cutting material in the two coordinate planes is realized by the mechanical arm of the robot 24. If the deviation exists, high-precision deviation detection is realized through the camera 19, and deviation information is synchronously transmitted to control software of the numerical control cutting machine, so that the discharge image is corrected and a cutting image is output according to the position deviation and the deviation angle calculated by the sampling signals, and an accurate cutting image is obtained, so that high-precision cutting is performed.
