With respect to step S21 and step S22, whether it is the process of the control module 11 or the process of the upper computer 111, the process of step S21 is the same as the process of step S22.

For step S23, if step S23 is performed by the control module 11, step S23 may be implemented as a processing procedure implemented by the cooperation of the upper computer, each control module, and the laser in the control module 11, and the execution main bodies of the processing procedure are the upper computer, each control module, the laser, and the like in the control module; if the processing is performed by the upper computer 111, the step S23 may be understood as the processing performed by the upper computer controlling each control module and the laser, and the execution main body of the processing is only the upper computer, and in some examples, the processing may be understood as a function performed by a program configured in the upper computer.

Specifically, when implementing step S23, the upper computer 111 is specifically configured to:

The acquired real-time position information may be, for example, an encoder signal fed back by an encoder in the motion execution structure, or may be coordinates calculated from the encoder signal. For example, the real-time location information may be detected visually or by other sensors.

If the code spraying position information is the position information of a single position point needing code spraying, namely the position information of each position point needing code spraying is determined, then: the matching may mean that the real-time position information is the same as the code-spraying position information;

if each cutting position information is the position information of a single position point needing to be cut, namely the position information of each position point needing to be cut is determined, then: the matching may mean that the real-time position information is the same as the cutting position information.

If each code-spraying position information includes position information of a code-spraying start point of a single code-spraying pattern (further, position information of a code-spraying end point can also be included), then: the matching can mean that if the cutting code-spraying assembly moves to the code-spraying starting point of a code-spraying pattern when moving along the path, the real-time position information shows that the cutting code-spraying assembly moves to the code-spraying starting point of the code-spraying pattern, the real-time position information is considered to be matched with the corresponding code-spraying position information, and further, the cutting code-spraying assembly is considered not to be matched when the real-time position information shows that the cutting code-spraying assembly leaves the corresponding code-spraying end point;

if each piece of cutting position information is position information of a cutting start point of a single cutting pattern to be cut (the position information of the cutting end point is generally the same as the position information of the start point), then: the matching can be as follows: and if the real-time position information shows that the cutting code-spraying assembly moves to the position of the cutting starting point of one cutting pattern when moving along the path, the real-time position information at the moment is considered to be matched with the corresponding cutting position information.

Furthermore, the above judgment on matching can also be realized by combining factors such as speed, delay time and the like.

In the scheme, the path, the cutting time and the code spraying time of the cutting and code spraying process are determined by the control assembly according to the processing information, so that the workpiece does not need to be sent into different systems or do not need to perform two relative motions in different systems, the process flow is effectively simplified, and the efficiency is improved.

In one embodiment, referring to fig. 8, step S23 may include:

s231: determining layout information according to the processing information;

s232: and determining the target path information, the cutting information and the code spraying information according to the layout information.

The layout information represents the arrangement mode of the at least one cutting pattern and the at least one code spraying pattern in a preset two-dimensional plane; the size and shape of the preset two-dimensional plane are matched with the at least one workpiece to be processed, and the matching can be, for example, the combination of the same shape and the size smaller than or equal to the at least one workpiece to be processed.

The pattern layout in step S231 may be implemented in any existing or improved manner in the art, for example, the pattern layout may be performed on the basis of arranging as many patterns as possible.

In a specific implementation process, since the positions of the code spraying structure and the cutting structure are relatively fixed, and further the position deviation of the code spraying structure and the cutting structure is fixed, the system only adopts coordinates under a coordinate system to represent the position (for example, the position under the cutting coordinate system), then: the target path information and the code spraying information are related to the relative position deviation between the code spraying structure and the cutting structure.

In a specific implementation process, the motion path represented by the target path information may be a motion path of the cutting structure in a cutting coordinate system; the motion path represented by the target path information comprises a cutting motion path and a code spraying motion path.

The cutting motion path is a path required by the cutting structure to move when the cutting of the at least one cutting pattern is completed, and may be a continuous motion path corresponding to all cutting patterns or a scattered motion path.

The code spraying movement path is a path which is required to move by the cutting structure when the code spraying structure finishes the code spraying of the at least one code spraying pattern; it may be a continuous motion trajectory corresponding to all the code-sprayed patterns or a scattered motion path.

If the cutting motion path and the code spraying motion path are both continuous motion paths, then:

the tail end of the cutting motion path is connected with the head end of the code spraying motion track, and then, the cutting of all cutting patterns can be implemented firstly, and then the code spraying of all code spraying patterns can be implemented; or: the head end of the cutting motion path is connected with the tail end of the code spraying motion track, and then code spraying of all code spraying patterns can be carried out firstly, and then cutting of all cutting patterns can be carried out.

If at least one of the cutting motion path and the code spraying motion path is scattered, then:

in some examples, one or more code-spraying patterns may be sprayed after one or more cutting patterns are cut, and then other cutting patterns are cut after the code-spraying, and further, the cutting and the code-spraying may be performed alternately, wherein the cutting and the code-spraying may be configured in any order.

Step S222 may specifically include:

s2221: determining the cutting motion path and the cutting information according to the arrangement mode of each cutting pattern represented by the layout information;

s2222: and determining the code spraying movement path and the code spraying information according to the arrangement mode of each code spraying pattern represented by the layout information and the relative position deviation.

In the layout information, the cutting pattern and the code spraying pattern are on the same two-dimensional plane, in the actual processing process, the cutting structure is used for outputting laser during cutting, the code spraying structure is used for spraying code during code spraying, and the deviation of the cutting pattern and the code spraying structure needs to be considered in path planning, for example: and (3) projecting a position point of the code spraying in the two-dimensional plane obtained after layout to a coordinate of a cutting coordinate system to obtain (X, Y), and assuming that the deviation between the code spraying structure and the cutting structure is as follows: the deviation delta X is in the X-axis direction, at this time, if (X, Y) is taken as a position point needing code spraying, when the cutting code spraying assembly moves to the position point, the cutting structure actually reaches the position (X, Y), and the code spraying structure is at the position point of (X plus delta X, Y), so that when a path is planned, (supposing that factors such as time delay, movement speed and the like are not considered at this time), the position point needing code spraying is planned to be (X-delta X, Y), at this time, when the cutting structure reaches (X-delta X, Y), the code spraying structure reaches (X, Y), and further, code spraying can be favorably implemented at an accurate position, and influences caused by the deviation delta X are compensated.

Of course, after the poses of the code spraying structure and the cutting structure are reasonably configured and adjusted, the deviation may not be generated, or: the deviation may also be small and furthermore the influence of the deviation may also not be taken into account in some solutions, for example: the cutting motion path and the cutting information can be determined according to the arrangement mode of each cutting pattern represented by the layout information; and determining the code spraying movement path and the code spraying information according to the arrangement mode of each code spraying pattern represented by the layout information.

In one embodiment, referring to fig. 10, after step S22, the method may further include:

s24: determining following height information when the cutting code-spraying assembly moves;

s25: and adjusting the height of the cutting code spraying assembly relative to the workpiece to be processed through the height adjusting execution structure according to the real-time height information and the following height information.

The following height information represents the cutting following height and/or the code spraying following height of the cutting code spraying assembly relative to the workpiece to be processed; the following height information is determined according to at least one of the material, the thickness and the preset processing requirement of the workpiece to be processed, for example: when processing the work piece of different materials, different thickness, or be applied to and realize different processing requirements, the optional difference is followed the height information, wherein, if the quantity of work piece is a plurality of, can be under the condition of once processing, start, to the work piece change its cutting that requires in different materials, thickness, processing, spout a yard and follow the height. The following height information may be determined with human intervention or may be automatically determined.

The processing requirement may be, for example, precision requirement of cutting, code spraying, roughness requirement, etc., or may be, for example, a pre-specified following height value or value range.

In addition, if there are a plurality of workpieces, the corresponding relationship between different path portions and different workpieces or the corresponding relationship between different path portions and different following height information may be preset (manually and/or automatically set) in the path represented by the target path information, and in step S24, the upper computer may determine the current following height information according to the located path portion and the preset corresponding relationship, and further, the following height information determined in step S24 may be understood as the currently required following height information.

The processing of step S24 is the same for step S24 regardless of whether it is the processing of the control unit 11 or the processing of the upper computer 111.

In step S25, if step S25 is performed by the control module 11, step S25 may be a processing procedure implemented by the cooperation between the upper computer and the height-adjusting control module in the control module 11, and the execution main bodies of the processing procedure are the upper computer and the height-adjusting control module in the control module; if it is implemented by the upper computer 111, the step S25 may be understood as a processing procedure implemented by the upper computer control high-level control module, and an execution subject of the processing procedure is only the upper computer, and in some examples, the processing procedure may be understood as a function implemented by a program configured in the upper computer.

Specifically, when implementing step S25, the upper computer 111 is specifically configured to:

determining an altitude deviation between the real-time altitude information and the following altitude information;

and sending height deviation information representing the height deviation or adjustment information for making up the height deviation to a height-adjusting control module, so that the height-adjusting control module controls the action of the height-adjusting execution structure, and the height of the cutting code-spraying assembly can be adjusted along with the action of the height-adjusting execution structure. Furthermore, the height deviation can be effectively compensated after adjustment.

Among the above scheme, follow the height based on spouting the sign indicating number, can adjust the height when spouting the sign indicating number, and then follow through the height when spouting the sign indicating number, the guarantee spouts the sign indicating number effect.

Compared with the prior art, in most of the inkjet printers in the market, the inkjet structure is fixed, the plate is movable, the inkjet height cannot be automatically adjusted, and therefore the problems that the movable inkjet structure is inconvenient to adjust and disassemble and the like are solved.

In addition, the scheme realizes multiple purposes by highly following, avoids multiple startup caused by distinguishing the plates (thickness, materials, processing requirements and the like), further avoids waste caused by the startup, and saves manpower and material resources.

Referring to fig. 11, after integrating the above alternatives, the processing of the system can be understood by referring to the process of fig. 11, wherein:

the process of importing the machining map may correspond to the process of acquiring the machining information in step S21, and the machining information may be the machining map or information included in the machining map;

the process of stock layout may correspond to the processing process of step S221;

the process parameters set in the process of setting the process parameters can be, for example, target track information, and also can be, for example, the movement speed of the cutting code-spraying assembly, the laser power, and the like.

The processes of laser control, code spraying control, graphic processing, motion control, height adjustment control, execution mechanism, feedback signal, code spraying and cutting can be understood as the processing processes of steps S222, S23, S24 and S25.

In a specific example, the position of the start point of the code spraying (i.e. the position information of the start point of the code spraying in the code spraying position information mentioned above) may be determined by an upper computer, and therefore, unlike the existing code spraying machine, the external trigger signal may be used to control the start of code spraying in the specific example of the present invention.

On the basis of the system, under the condition that coordinates (namely real-time position information) and speed (the movement speed of a cutting code spraying assembly) are known, code spraying can be carried out at a constant speed stage in order to achieve the optimal code spraying effect, and a code spraying driver is controlled by combining delay time and speed matching, wherein the time for driving a lower spray head to spray codes is very short and can be considered to be instantly finished, and code spraying is finished when the spray head reaches an end position.

For the solutions to which the above alternatives relate, it is also noted that:

under the condition that each alternative above is not adopted, laser cutting machine is when carrying out panel processing, because the start-up expense is expensive, so need to spout the sign indicating number to different panel (wherein difference can indicate that panel thickness is different, also can indicate customer's different cutting demands) and distinguish, later, can carry out "one sword to panel and cut", whole process technology is complicated, manpower and spout a yard equipment cost height, and efficiency is extremely low, and, the slightly high yard device that spouts of intelligent degree that current numerical control workshop processing was used, mostly large-scale equipment, it is inconvenient to use.

Aiming at the problem of pain points in the field of laser cutting, in the specific scheme of the invention, the code spraying structure is integrated in the cutting system, so that the cutting code spraying system is formed, intelligent corresponding parts do not need to be additionally configured, and the code spraying structure with small size, convenience in disassembly and assembly and high integration level is favorably realized.

Furthermore, because the cutting and code spraying height is in follow-up, a plurality of plates can be identified and distinguished together, the problem of repeated starting up waste is avoided, the functions of the upper computer are combined, the efficient cutting of one person and one machine can be realized, and the code spraying pattern is not limited.

Aiming at the processes and flows for distinguishing and identifying cut workpieces (such as plates) in part of the prior art; the method is generally divided into code spraying before cutting and code spraying at the later stage, if code spraying before cutting is selected, in the cutting process, in order to avoid damaging code spraying, the requirements on a code spraying path and a feeding path are strict, and the process is complex; if the later code spraying is selected, the secondary code spraying processing needs to be carried out on the cut plates due to the low integration level of the existing code spraying form, and the efficiency is low. Correspondingly, the scheme of the embodiment of the invention is not limited to code spraying or cutting firstly, and further has various possibilities of process sequences.
