Detailed Description
It should be noted that, in the case of no conflict, the embodiments of the present application and the technical features of the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as unduly limiting the present application.
In one aspect, a print size calibration method is provided in an embodiment of the present application, and in some embodiments, referring to fig. 1, the print size calibration method includes the following steps:
s1: determining the actual size: the printing plate is driven to advance in a preset direction so that the sensor 402 detects the first sensing position and the second sensing position of the printing plate, and the actual size between the first sensing position and the second sensing position of the printing plate is obtained.
The actual size between the first sensing position and the second sensing position of the printing plate refers to the linear distance between the first sensing position and the second sensing position of the printing plate along the preset direction under the current temperature and humidity environment of the printing plate.
S2: determining the size deviation ratio: and comparing the actual size with a preset standard size to obtain a size deviation ratio.
It is understood that the preset standard size refers to a design size of the first sensing position and the second sensing position of the printing plate along a preset direction.
The dimension deviation ratio is the ratio of the actual dimension of the printing plate to the designed dimension under the current temperature and humidity environment.
S3: determining a print adjustment ratio: and obtaining a printing adjustment proportion according to the size deviation proportion, and adjusting the printing size according to the printing adjustment proportion.
It is understood that the print size refers to the size of the print content that needs to be printed onto the print plate.
According to the printing size calibration method provided by the embodiment of the application, the size deviation ratio of the actual size to the preset standard size is determined by acquiring the actual size of the printing plate, and the printing size of the printing content is adjusted by utilizing the size deviation ratio, so that the printing size of the printing content can be adaptively adjusted according to the size change of the printing plate under different temperature and humidity environments, the probability of occurrence of problems such as deviation out of tolerance, skew, occurrence of the printing content outside the printing plate and the like caused by the size change of the printing plate is reduced, and the adaptability of the printing equipment to different working conditions is improved.
In some embodiments, after the actual print size is determined, and the print board enters the position of the job to be printed, the print board stops advancing, and the print content conforming to the actual print size is printed on the print board. The subsequent printing plate repeats the above flow, and batch printing operation is realized.
It should be noted that the specific manner in which the sensor 402 detects the first sensing position and the second sensing position of the printing plate is not limited.
In some embodiments, the first sensing location and the second sensing location of the print plate are both present within the sensing range of the sensor 402.
In other embodiments, determining the actual dimensions specifically includes: the printing plate is driven to advance along the preset direction, the first sensing position and the second sensing position trigger the sensing of the sensor 402 in sequence, and the advance distance required by the twice sensing of the sensor 402 of the printing plate is obtained, wherein the advance distance is the actual size.
Specifically, during the process of the printing plate advancing along the preset direction, the sensor 402 senses the first sensing position and the second sensing position of the printing plate in time sequence, so as to obtain an advancing distance required by the printing plate to trigger the sensing of the sensor 402 twice, wherein the advancing distance is equal to the actual size between the first sensing position and the second sensing position of the printing plate.
That is, the sensor 402 is stationary relative to the printing plate advancing along the preset direction, and the first sensing position and the second sensing position of the printing plate may sequentially pass through the sensor 402 along the preset direction, so that the sensor 402 only needs to detect the first sensing position or the second sensing position at a time, which reduces the amount of data required to be processed by the sensor 402 for a single detection, and on one hand, is beneficial to improving the data processing speed; on the other hand, the induction component with low cost is favorable to be adopted, and the production cost of the equipment is reduced. The subsequent printing plates can also pass through the sensor 402 continuously and can be sensed by the trigger, so that continuous assembly line operation is convenient to realize, and the printing efficiency and the detection efficiency of the printing equipment are improved.
In some embodiments, causing the first sensing location and the second sensing location to sequentially trigger sensing by the sensor 402 specifically includes: after the first sensing position of the printing plate triggers the sensing of the sensor 402, the sensor 402 is controlled to be closed, and after the printing plate is driven to continuously move for a preset distance, the sensor 402 is controlled to be opened until the second sensing position of the printing plate triggers the sensing of the sensor 402.
It will be appreciated that the range of dimensional changes of the printing plate has a limit value and the preset distance should be less than the limit value of dimensional changes.
That is, the sensor 402 is turned off after the first sensing position is triggered, until the printing plate continues to move a preset distance and then is turned on again, during which the influence of other environmental factors on the sensor 402 can be reduced, and the risk that the false triggering of the sensor 402 occurs to influence the acquisition of the actual size of the printing plate is reduced.
In some embodiments, the distance of advance required to obtain the sensing of the two triggers of the print plate sensor 402 specifically includes: acquiring a first reference moment sensed by a first sensing position trigger sensor 402 of the printing plate; acquiring a second reference moment sensed by a second sensing position trigger sensor 402 of the printing plate; the advance distance required for the sensing of the print plate twice triggering sensor 402 is obtained from the first reference time and the second reference time.
Specifically, the sensor 402 senses the first sensing position and the second sensing position of the printing plate in sequence in the process that the printing plate advances along the preset direction, so that the first reference time sensed by the first sensing position trigger sensor 402 of the printing plate and the second reference time sensed by the second sensing position trigger sensor 402 of the printing plate are obtained, and the required advancing distance of the sensing of the second sensing sensor 402 of the printing plate is obtained according to the first reference time and the second reference time, and is equal to the actual size between the first sensing position and the second sensing position of the printing plate.
That is, the sensor 402 obtains the advance distance by converting only two times when the first sensing position and the second sensing position of the printing plate are acquired to trigger the sensing. Therefore, the calculation processing requirement on the equipment is low, and the calculation result can be obtained quickly, so that the calculation efficiency is improved, the cost can be saved, and the equipment structure can be simplified.
In some embodiments, obtaining the advance distance required for the printing plate to twice trigger the sensing of the sensor 402 based on the first reference time and the second reference time comprises: calculating a time difference value between the second reference time and the first reference time; acquiring a speed parameter of the printing plate between the second reference time and the first reference time; and obtaining the advancing distance according to the time difference value and the speed parameter.
Specifically, the sensor 402 senses the first sensing position and the second sensing position of the printing plate in sequence in the process of advancing along the preset direction, so that the first reference time sensed by the first sensing position trigger sensor 402 of the printing plate and the second reference time sensed by the second sensing position trigger sensor 402 of the printing plate can be obtained, the time difference between the second reference time and the first reference time can be calculated, the advancing distance of the printing plate can be calculated according to the time difference and the speed parameter, and the advancing distance is equal to the actual size between the first sensing position and the second sensing position of the printing plate.
That is, the time difference is obtained through the calculation of the first reference time and the second reference time, and then the advancing distance is obtained through the calculation of the time difference and the speed parameter, namely the displacement of the printing plate is obtained through the time-speed relation, and the operation mode is simple and visual, so that the error data can be conveniently screened in the operation process; the related calculation parameters are few, and the calculation steps are simple, so that the data processing efficiency is improved, the requirement of the performance of operation is low, the cost is saved, and the equipment structure is simplified.
The specific method for obtaining the dimensional deviation ratio is not limited. In some embodiments, the size deviation ratio may be obtained by converting the actual size with a preset standard size. The specific method of conversion is not limited, and in some embodiments, the size deviation ratio is calculated by combining the actual size, the preset standard size and the error of the system itself.
In other embodiments, the dimension deviation ratio is a ratio of the actual dimension to a predetermined standard dimension.
For example, the actual size of the printing plate is 122mm (millimeter), the preset standard size is 120mm, and the size deviation ratio is 122/120×100% = 101.67%.
The specific method of obtaining the print adjustment ratio from the size deviation ratio is not limited.
The method for obtaining the printing adjustment ratio according to the size deviation ratio may be to obtain the printing adjustment ratio by converting the size deviation ratio in combination with a systematic error; the print adjustment ratio may be equal to the size deviation ratio, for example, 101.67% and 101.67%.
The specific method of obtaining the actual print size is not limited. The size deviation ratio can be obtained by converting the print adjustment ratio with the print size. The specific conversion method is not limited. In some embodiments, the actual print size is calculated by combining the print adjustment ratio, the preset print size, and the error of the system itself.
In other embodiments, adjusting the print size according to the print adjustment ratio specifically includes: multiplying the printing adjustment proportion by a preset printing size, and taking the product of the printing adjustment proportion and the preset printing size as an actual printing size.
It can be understood that the actual print size refers to a print size that is actually printed on the print board after being adjusted according to the print adjustment ratio, and the size deviation from the preset standard size is within a reasonable range.
In some embodiments, before determining the actual size, the print size calibration method further comprises: and (5) detecting precision by the debugging equipment. To determine that the operating state of each element of the device is normal, thereby reducing the adverse effect of the operating accuracy of the device on the measurement result.
In some embodiments, the debugging device detection precision specifically includes the following steps:
s01: determining a debugging size: the standard board is driven to advance along a preset direction, so that the sensor 402 detects the third sensing position and the fourth sensing position of the standard board, and the debugging size between the third sensing position and the fourth sensing position of the standard board is obtained.
It will be appreciated that the material used for the standard plate is less affected by the temperature and humidity in the environment.
It can be understood that in the temperature and humidity environment of the expected use working condition of the equipment, the dimensional change generated by the influence of the temperature and humidity in the environment of the standard board is always within the allowable error range of the design size.
The debugging size refers to the linear distance between the third sensing position and the fourth sensing position of the index plate along the preset direction.
S02: determining the dimensional deviation: comparing the debugging size with a preset debugging size to obtain a size deviation.
The preset debugging size is the design size of the third sensing position and the fourth sensing position of the index plate along the preset direction.
S03: debugging equipment precision: and debugging the device so that the dimensional deviation is smaller than or equal to the preset dimensional deviation.
It can be understood that after the dimensional deviation is obtained, comparing the dimensional deviation with a preset dimensional deviation, and if the dimensional deviation is smaller than or equal to the preset dimensional deviation, starting to determine the actual dimension; if the size deviation is larger than the preset size deviation, debugging equipment is needed, and the steps of detecting the precision of the debugging equipment are repeated until the size deviation is smaller than or equal to the preset size deviation.
It should be noted that the specific method for obtaining the size deviation according to the debug size and the preset debug size is not limited. Illustratively, a difference between the debug size and the preset debug size is taken as the size deviation.
Principle of the step of detecting precision of the debugging equipment: by comparing the debug size of the standard board with the preset debug size, whether the printing apparatus 40 meets the required apparatus error range can be estimated. The parameters related to the principle are simpler, and the method for acquiring the parameters refers to the step S1, so that the equipment structure and the calculation program are not required to be additionally increased, the cost can be saved, and the equipment structure can be simplified.

After the actual size is obtained, the parameter calculation module compares the actual size with a preset standard size, and the ratio of the actual size to the preset standard size is taken as a size deviation ratio.
After the size deviation proportion is obtained, the parameter calculation module takes the size deviation proportion and the printing adjustment proportion to be equal, finally the parameter calculation module multiplies the printing adjustment proportion and the preset printing size, takes the product of the printing adjustment proportion and the preset printing size as the actual printing size, and adjusts the printing content according to the actual printing size.
