[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Figure 1 A module block diagram of a scribing knife control system provided in an embodiment of the present invention.

[0033] like Figure 1 As shown, a scoring knife control system includes a PLC control circuit and a temperature control circuit;

[0034] The PLC control circuit is used to import the line cutting data, and obtain the preset reference control data corresponding to the preset channels corresponding to each line cutting knife from the preset database, and perform difference analysis on each preset reference control data according to the line cutting data to obtain the line cutting knife adjustment value corresponding to each preset channel;

[0035] The temperature control circuit is used to perform voltage conversion on each of the scoring knife adjustment values ​​to obtain voltage values ​​corresponding to each of the preset channels, and to perform temperature conversion on each of the voltage values ​​to obtain temperature values ​​corresponding to each of the preset channels, and to heat or cool the corresponding scoring knife according to each of the temperature values.

[0036] It should be understood that the scribed line data is obtained by measuring with a scribed line detector and is manually inputted through a touch screen.

[0037] Specifically, according to the compensation amount (i.e., the compensation control amount) provided by each channel (i.e., the preset channel), the corresponding control value is provided to the single-phase voltage regulation module controller of each channel through the output module, the control value is converted into the corresponding voltage (i.e., the voltage value), and the corresponding voltage value is converted into temperature energy (i.e., the temperature value) through the heater to compensate the engraving knife, thereby obtaining the result of automatic control of engraving.

[0038] In the above embodiment, the line engraving data is used to perform a difference analysis on each preset reference control data to obtain a line engraving knife adjustment value, the voltage of each line engraving knife adjustment value is converted to a voltage value, the temperature of each voltage value is converted to a temperature value, and the corresponding line engraving knife is heated or cooled according to each temperature value, so that the line engraving can be stabilized, thereby controlling the depth of the line engraving of the pull-ring cover, preventing the pull-ring cover from being directly scrapped due to excessively deep line engraving, or preventing the batch scrapping of the V-card due to the pull-ring cover engraving being too shallow, thereby reducing the risk of quality accidents, ensuring the stability of quality, saving manpower and material resources, improving the yield rate, and improving work efficiency.

[0039] Optionally, as an embodiment of the present invention, the PLC control circuit is specifically used for:

[0040] Importing the scoring data, and obtaining the preset reference control data corresponding to the preset channels corresponding to each scoring knife from the preset database;

[0041] Establishing a function according to the line data to obtain a line data function group; and establishing a function according to each of the preset reference control data to obtain a reference control data function group corresponding to each of the preset reference control data;

[0042] Perform difference calculations on the scoreline data function group and each of the reference control data function groups to obtain scoreline differences corresponding to each of the preset channels;

[0043] Compare each of the scribed line differences with the preset adjustment value interval of the corresponding preset channel respectively; if the scribed line difference is within the corresponding preset adjustment value interval, use the preset compensation amount corresponding to the preset difference interval as the compensation control amount of the corresponding preset channel;

[0044] The current temperature of each scribing knife is obtained, and the current temperature of each scribing knife and the corresponding compensation control amount are respectively summed and calculated to obtain the scribing knife adjustment value corresponding to each preset channel.

[0045] It should be understood that if the scale line difference is not within the corresponding preset adjustment value interval, 0 is used as the compensation control amount of the corresponding preset channel.

[0046] It should be understood that the cold machine start-up operation mode is to call corresponding data information from the preset program (ie, the preset database) for loading, and provide reference control data (ie, the preset reference control data) to multiple channels respectively.

[0047] Specifically, in the warm-up start-up operation mode, the engraved data is collected and loaded into the system, and the reference control data is provided to multiple channels after updating. According to the reference control data provided by each channel (i.e., the preset reference control data), a data function group (i.e., the reference control data function group) that can be recognized by program control is obtained through data type and expression form conversion.

[0048] It should be understood that updating refers to updating through manual data entry, that is, the data entered this time replaces the data entered last time.

[0049] It should be understood that data type conversion means, for example: converting 16-bit data into 32-bit data. The conversion of expression form is to convert a number into a proportional relationship, that is, data conversion should be to convert 0~27648 into a ratio of 0~100. For example, the minimum value of this number is 0 and the maximum value can only be 100, that is, within the ratio of 0 to 100.

[0050] It should be understood that the data function groups are respectively substituted into the control program (ie, the PLC control circuit) for step-by-step calculation, processing and conversion to obtain the compensation amount corresponding to each channel (ie, the compensation control amount).

[0051] Specifically, the entered data (i.e., the engraved line data) is converted and then added or subtracted from the internal preset reference data (i.e., the preset reference control data) to obtain three results: larger than the preset data (i.e., the preset reference control data), smaller than the preset data (i.e., the preset reference control data), and equal to the preset data (i.e., the preset reference control data). There are multiple preset intervals (i.e., the preset difference intervals) in the program. The calculation result (i.e., the engraved line data difference) is compared and screened with the preset interval (i.e., the preset difference interval) to see which interval (i.e., the preset difference interval) the data falls into. Different compensation control amounts are output in different intervals (i.e., the preset difference intervals).

[0052] In the above embodiment, the adjustment value of the scoring knife is obtained by performing a difference analysis of the scoring data with respect to each preset reference control data, so as to achieve the purpose of automatically adjusting the scoring line, so that the scoring line is always stable within the standard control range, and the product quality is effectively guaranteed.
