It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.

It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
As described in the background art, the related art engraving method has a problem that the defective product of engraving frequently occurs, and the inventor has found that the problem is caused by errors in the operating parameters of some engravers or the engraving parameters determined according to the image to be engraved due to the complicated operating environment of the engravers, and the engraved product is discarded as a defective product when the errors are accumulated to a certain extent during the engraving process. For example, in the process of the main shaft of the engraving machine performing engraving in each circle, there is no way to maintain a constant rotation speed all the time, and there will be fluctuation of the rotation speed, which will cause the difference of the engraving number and position of the hole processing in each circle; for another example, the engraving parameters generated according to the layout shape are not accurate enough, which also causes the difference of the engraving number of the mesh processing of each circle. When the carving error of one circle is taught, the carving error of the other circle can not be scrapped, but if the carving error of each circle is not adjusted in time and continuously processed, the carving error of each circle can be accumulated, and when the error in the carving process is accumulated to a certain degree, the carved product can be scrapped to become a defective product.
For the above reasons, the present invention provides an encoder signal based engraving method, apparatus and computer device.
Fig. 1(a) and fig. 1(b) are schematic diagrams of two application environments of an encoder signal-based engraving method according to an embodiment of the present application. When the engraving machine works normally, the main shaft of the engraving machine drives the printing roller to rotate at a high speed under the drive of the alternating-current servo motor, the engraving head is driven by the head leaning motor to press the surface of the printing roller driven by the main shaft, and the trolley drives the engraving head to move continuously at a low speed or move along the axial direction of the printing roller in a stepping mode under the drive of the servo motor screw rod. The industrial personal computer in the electric carving control system converts a pattern to be processed by the carving machine into digital image information, the driving module converts a digital signal into an analog signal through the digital-analog converter, and the carving head is controlled to carve carving points with different sizes and depths on the surface of the plate roller copper layer at a fixed frequency (4K-12 KHz), so that a mesh point is formed.
Referring to fig. 2, fig. 2 is a schematic flowchart of an embodiment of a carving method based on an encoder signal. In one embodiment, as shown in fig. 2, there is provided an encoder signal based engraving method, the method comprising:
Step S210, acquiring an indication signal output by a main shaft encoder of the engraving machine in real time, and acquiring an engraved control signal corresponding to an engraved cell of the plate roller in the current circle when receiving the indication signal, wherein the indication signal is used for marking the starting point of the plate roller rotating back to the circle.
The engraving machine of the embodiment is an electronic engraving machine. The indicating signal is a signal for indicating that the plate roller rotates back to the starting point of one circle. Generally, the output signal of the spindle encoder outputs a zero pulse Z every revolution in addition to A, B two phases (the phase difference of the signal sequence of A, B two channels is 90 degrees), the spindle encoder sends a pulse every revolution, which is called a zero pulse or a mark pulse (namely a Z-phase signal), the zero pulse is used for determining a zero position or a mark position, and the indication signal of the implementation is a Z-phase signal. The engraved cells of the current ring refer to the cells that have been engraved in the current ring. The engraved control signal is an actual control signal for driving the engraving head to engrave in the current circle to obtain the mesh.
And step S220, judging whether the carved control signal is matched with a preset standard carving control signal of the current circle.
The standard engraving control signal is a standard control signal for driving the engraving head to engrave in the current circle and is used as a reference signal for judging whether the current circle is engraved with deviation or not. Specifically, the standard control signal may be a control signal with power that converts image information into a control signal with power that can drive a stepping motor or a servo motor by transmitting the pattern information of the pattern to be engraved to a controller of the engraving machine.
And step S230, if the engraved control signal is not matched with the standard engraving control signal, adjusting the control signal to be engraved of the next circle of mesh to be engraved of the plate roller.
In this step, when the engraved control signal and the standard engraving control signal are not matched, it is indicated that the engraving result of the current circle is not completely standard, and an engraving error exists, which affects the engraving of the plate roller in the next circle.
And S240, engraving the mesh to be engraved of the plate roller according to the adjusted control signal to be engraved.
In the step, the adjusted control signal to be engraved is used for adaptively engraving the mesh to be engraved in the next circle of the plate roller, so that the situation that the accumulation of engraving errors in each circle is too large to exceed the allowable range and defective products are generated can be avoided.
It should be noted that the current circle of the embodiment does not refer to a certain circle of the plate roller in the engraving process, and may be a first circle, a second circle, a third circle, and the like, and is not limited specifically here. Further, the next round means a round which is engraved next after the engraving of the previous round is completed. For example, when the previous turn is the first turn, the next turn is the second turn. When the engraving machine is switched from the current circle to the next circle for engraving, the method of the embodiment can be adopted until the engraving of each circle of the plate roller is completed.
It can be understood that, in this embodiment, through when receiving the pilot signal, when version roller carved the cave of round promptly, obtain that current circle drive carving head carries out the carved control signal and standard sculpture control signal that the cave was carved and compare, if carved control signal and standard sculpture control signal when not matching, it leads to having engraving error not to indicate that the sculpture result of current circle is the special standard, then carry out the adaptability adjustment to the control signal of waiting to carve of next circle, can adjust this engraving error in the sculpture process of next circle, it causes the product to scrap to avoid engraving error to lead to the accumulative error at the accumulation of each circle too big, the sculpture qualification rate based on encoder signal has been improved greatly.
Referring to fig. 3, fig. 3 is a schematic flowchart of another encoder signal-based engraving method according to an embodiment. The engraving method based on encoder signals in this embodiment further refines the control signal to be engraved for adjusting the mesh to be engraved of the next circle of the plate roller in step S230. In one embodiment, as shown in fig. 3, there is provided another encoder signal based engraving method, the method comprising:
Step S310, acquiring an indication signal output by a main shaft encoder of the engraving machine in real time, and acquiring an engraved control signal corresponding to an engraved cell of the plate roller in the current circle when receiving the indication signal, wherein the indication signal is used for marking the starting point of the plate roller rotating back to the circle, and the engraved control signal comprises a plurality of engraved pulse signals.
And S320, judging whether the engraved control signal is matched with a preset standard engraving control signal of the current circle, wherein the standard engraving control signal comprises a plurality of standard engraving pulse signals of the current circle.
In this step, in one possible implementation, the engraved control signal and the standard engraving control signal do not match if the number of the plurality of engraved pulse signals and the plurality of standard engraving pulse signals do not coincide. Specifically, one engraving pulse signal drives one engraving to obtain one engraving point. If the number of the engraved pulse signals is consistent with that of the standard engraved pulse signals, it is indicated that the actual engraved cells are consistent with the preset standard engraved cells, the engraving error is considered to be almost zero, and adjustment is not needed.
Step S330, if the engraved control signal and the standard engraving control signal do not match, determining a deviation parameter between the number of engraved cells and the number of standard engraving cells, where the number of engraved cells is associated with the number of engraved pulse signals, and the number of standard engraving cells is associated with the number of standard engraving pulse signals.
The deviation parameter is used for representing the deviation between the actual result of carving the mesh and the preset result of carving the standard mesh. Generally, each engraving pulse signal drives the engraving head to engrave once to obtain one cell, and the quantity of the acquired engraving pulse signals can be corresponding to the quantity of the engraved cells. For example, when the engraving head is driven to engrave one cell at a time by each engraving pulse signal, the number of engraved cells is identical to the number of engraved pulse signals. Similarly, the number of the standard engraving cells is consistent with that of the standard engraving pulse signals. In this embodiment, optionally, the deviation parameter at least includes a deviation type, and may further include a deviation amount. The type of deviation refers to the type of deviation, and the deviation amount refers to the degree of deviation.
And S340, adjusting the control signal to be engraved of the mesh to be engraved in the next circle of the plate roller according to the deviation parameter.
And S350, engraving the to-be-engraved cells of the plate roller according to the adjusted to-be-engraved control signal.
Referring to fig. 4, fig. 4 is a schematic view of a detailed flow of step S340 in fig. 3 according to an embodiment. As shown in fig. 4, in a possible embodiment, when the deviation parameter includes a deviation type, the step S340 of adjusting the control signal to be engraved in the next round of cells to be engraved on the printing roll according to the deviation parameter includes:
and S341, acquiring a control signal to be engraved of the next circle of mesh to be engraved, wherein the control signal to be engraved comprises a plurality of pulse signals to be engraved, and each pulse signal to be engraved corresponds to one pulse period.
And S342, adjusting the pulse period corresponding to the plurality of pulse signals to be engraved according to the deviation type so as to adjust the time when the engraving head engraves the next circle of mesh to be engraved.
In this embodiment, specifically, the pulse signal to be engraved is a sine wave signal, and the engraving head is driven to engrave a cell on the plate roller at a sine wave trough position of the pulse signal to be engraved. Therefore, the adjustment of the pulse period of the pulse signal to be engraved changes the moment when the engraving head engraves, and changes the positions of the mesh holes to be engraved on the plate roller under the condition that the plate roller performs uniform circular motion, thereby adjusting the engraving error. Specifically, the pulse period is shortened, so that the position of the sine wave trough comes in advance, namely the carving speed is improved; extending the pulse period delays the position of the sine wave trough, i.e. the speed of engraving is reduced.
Optionally, the offset type includes a positive offset and/or a negative offset. A positive deviation indicates that the number of actual engraved cells is greater than the number of standard engraved cells, and a negative deviation indicates that the number of actual engraved cells is less than the number of standard engraved cells. Wherein if the number of engraved cells is greater than the number of standard engraved cells, the type of deviation is a positive deviation; if the number of engraved cells is less than the number of standard engraved cells, the type of deviation is a negative deviation. Specifically, when the type of deviation is a positive deviation, the pulse period is extended so that the position of the sine wave valley comes with a delay, i.e., so that the speed of engraving is reduced. When the type of deviation is a negative deviation, the pulse period is shortened so that the position of the sine wave trough comes ahead, i.e., the speed of engraving is increased.
In a possible embodiment, the step S342 of adjusting the pulse periods corresponding to the pulse signals to be engraved according to the deviation type may include:
if the deviation type is positive deviation, shortening the pulse period corresponding to at least one target pulse signal to be engraved in the plurality of pulse signals to be engraved; and if the deviation type is a negative deviation, prolonging the pulse period corresponding to at least one target pulse signal to be engraved in the plurality of pulse signals to be engraved.
In this embodiment, when the type of deviation is a positive deviation, it indicates that the number of engraved pulse signals corresponding to the engraved cells in the current circle is too large, and the number of pulse signals to be engraved in the next circle is too small, so that it is necessary to extend the pulse period of the pulse signals to be engraved in the next circle. When the deviation type is a positive deviation, it indicates that the number of engraved pulse signals corresponding to the engraved cells of the current circle is too small, and the number of pulse signals to be engraved of the next circle is too large, so that the pulse period of the pulse signals to be engraved of the next circle needs to be shortened.
For example, the controller calculates that the current circle has 10 standard engraving pulse signals, and the next circle has 11 standard engraving pulse signals, so that in the current circle, the engraving head should be driven to engrave 10 cells in the current circle of the plate roller according to the 10 standard engraving pulse signals. However, if the rotation speed of the plate roller fluctuates, only 9 engraved cells are actually engraved, that is, the deviation type is negative deviation, 1 standard engraving pulse signal remains in the current circle, and the next circle needs to be engraved according to 11+1 ═ 12 engraving pulse signals, so that the pulse period of the pulse signal to be engraved in the next circle needs to be shortened, the engraving speed is increased, and the engraving error accumulation is avoided. Similarly, when the deviation type is negative deviation, the pulse period of the pulse signal to be engraved in the next circle needs to be prolonged, so that the engraving speed is reduced.
It should be noted that, in this embodiment, the pulse period corresponding to at least one target pulse signal to be engraved in the plurality of pulse signals to be engraved may be adjusted. The target pulse signals to be engraved are front N pulse signals to be engraved in the plurality of pulse signals to be engraved, wherein N is the number of the target pulse signals to be engraved. For example, when the number of the pulse signals to be engraved in the target is one, the first pulse signal to be engraved in the plurality of pulse signals to be engraved is the target pulse signal to be engraved; for another example, when the number of the pulse signals to be engraved is two, the first and second pulse signals to be engraved in the plurality of pulse signals to be engraved are the target pulse signals to be engraved.
It will be appreciated that all of the pulse signals to be engraved may also be adjusted. And this implementation is through treating the sculpture pulse signal with the first N targets in a plurality of pulse signals of treating the sculpture and adjusting, only treats the sculpture pulse signal adjustment to the target, need not adjust all pulse signals of treating the sculpture, and then only the target treats the cave sculpture position that sculpture pulse signal corresponds and has slight deviation, and the non-target in a plurality of pulse signals of treating the sculpture treats the sculpture pulse signal and can carve according to predetermined cave sculpture position, has improved whole cave sculpture's accuracy.
In a possible embodiment, if the deviation type further includes a deviation amount, the step S340 of adjusting the control signal to be engraved in the next round of cells to be engraved on the printing roll according to the deviation parameter includes:
and determining a plurality of gradually changed adjusting parameters according to the deviation amount. And adjusting the pulse period corresponding to the pulse signals to be engraved step by step according to the adjustment parameters.
In the present embodiment, a plurality of adjustment parameters for gradual change are determined in accordance with the deviation amount, so that the pulse period is adjusted in accordance with the plurality of adjustment parameters. Specifically, the deviation amount includes a deviation engraving pulse signal. The deviation carving pulse signal refers to a carving pulse signal of the difference between the carving pulse signal of the current circle and the standard carving pulse signal. For example, the current loop includes three standard engraving pulse signals of a1, a2 and A3, and if the engraved pulse signals are a1 and a2, the offset engraving pulse signal is A3. For another example, the current turn includes three standard engraving pulse signals of a1, a2 and A3, the next turn includes three standard engraving pulse signals of B1, B2 and B3, if the engraved pulse signals are a1, a2, A3 and B1, the deviation engraving pulse signal is B1, and the control signal to be engraved of the next turn includes two pulse signals to be engraved of B2 and B3. Firstly, determining a deviation pulse period according to the deviation carving pulse signals, wherein the deviation pulse period is equal to the sum of the pulse periods corresponding to each deviation pulse signal, and then dividing the deviation pulse period into a plurality of gradually-changed pulse periods as adjustment parameters for adjustment. The present embodiment is not particularly limited to the manner of dividing the pulse period of the deviation into the plurality of adjustment parameters that are gradually changed.
The plurality of gradually changed adjustment parameters refer to the gradual change of the adjustment parameters. Specifically, the multiple adjustment parameters that gradually change in this embodiment means that the multiple adjustment parameters gradually decrease, so that the adjustment amplitude of the pulse period corresponding to the multiple pulse signals to be engraved gradually decreases. The adjustment parameter is a parameter for adjusting the pulse period. For example, when the deviation type is a negative deviation, after three target pulse signals to be engraved are determined, the pulse period of the first target pulse signal to be engraved is shortened 3/4 (for example, the pulse period of 1 microsecond is shortened to 1/4 microseconds), the pulse period of the second target pulse signal to be engraved is shortened 1/2, and the pulse period of the third target pulse signal to be engraved is shortened 1/4. For another example, when the type of the deviation is a positive deviation, after three target pulse signals to be engraved are determined, the pulse period of the first target pulse signal to be engraved is extended 3/4 (for example, the pulse period of 1 microsecond is extended to 7/4 microseconds), the pulse period of the second target pulse signal to be engraved is extended 1/2, and the pulse period of the third target pulse signal to be engraved is extended 1/4.
It can be understood that the pulse signal to be engraved is adjusted by the gradually changing adjustment parameters, so that sudden change of the engraving position is avoided, the engraving error is smoothly and gradually reduced, and the accuracy of adjusting the engraving position can be improved.
Optionally, in a manner of determining a deviation parameter between the number of engraved cells and the number of standard engraved cells, a difference value between the number of engraved cells and the number of standard engraved cells may be obtained, and the difference value is used as the deviation amount; if the number of the engraved cells is greater than the number of the standard engraved cells, the type of deviation is a positive deviation; if the number of engraved cells is less than the number of standard engraved cells, the type of deviation is a negative deviation.
Referring to fig. 5, fig. 5 is a schematic flowchart of another engraving method based on encoder signals according to an embodiment. As shown in fig. 5, another encoder signal based engraving method is provided, the method comprising:
step S510, before receiving the indication signal, receiving, in real time, an accumulated engraving control signal corresponding to an accumulated engraving cell in which the plate roller performs partial engraving in the current circle from the spindle encoder, where the accumulated engraving control signal includes a plurality of accumulated engraving pulse signals.
The accumulated engraving cells refer to cells obtained by partially engraving before the current ring finishes engraving for one circle. The cumulative engraving control signal is a cumulative engraving pulse signal including a plurality of signals for driving the engraving head to perform partial engraving in the current circle.
S520, judging whether the accumulated number of the accumulated engraving pulse signals reaches a preset accumulated number, wherein the preset accumulated number is larger than the number of the standard engraving pulse signals in the standard engraving control signals.
In this step, the preset accumulated number may be set as needed. Typically, the predetermined cumulative number is not greater than 1.2 times the number of standard engraving pulse signals. For example, if the number of standard engraving pulse signals is 10, the preset cumulative number is generally set to a natural number of 11 to 12.
