[0045] Specifically, in order to realize efficient and accurate blade head 11 pressure control, the application further provides the digital-to-analog conversion module 5 and the electric proportional valve 6. The digital-to-analog conversion module 5 is in signal connection with the control module 3 and receives a first control signal sent by the control module 3 according to the plurality of first preset blade pressures, the first control signal being a digital signal, the digital-to-analog conversion module 5 converts the digital signal into a second control signal, the second control signal being an analog signal, and the electric proportional valve 6 receives the second control signal to control the output blade pressure of the blade head 11, so that the control module 3 can generate a continuously changing signal according to needs to more finely adjust the state of the electric proportional valve 6, thereby realizing accurate regulation of the blade pressure.

[0046] In an embodiment of the application, the digital-to-analog conversion module 5 adopts a Mitsubishi AJ65SBT2B-64DA model, the analog current output is 4 to 20 mA, the digital input value is 0 to 12000, the precision can reach ±0.2% when the environmental temperature is 25±5℃, and the highest resolution is 1.33μA.

[0047] As shown in the cutting device, Figure 1 As shown, in some embodiments, the cutting device further comprises a third detection module 7, the third detection module 7 is in signal connection with the control module 3 and is used to detect the position information of the photovoltaic glass to be cut to obtain a next cutting point position serial number, the control module 3 has a preset point position serial number threshold value, if the cutting point position serial number is greater than or equal to the preset point position serial number threshold value, the control module 3 corrects the first preset blade pressure to a second preset blade pressure, and controls the output blade pressure of the blade head 11 according to the second preset blade pressure.

[0048] Specifically, in order to improve the safety and flexibility of the photovoltaic glass cutting operation, the third detection module 7 is further arranged, the third detection module 7 is in signal connection with the control module 3 and is used for detecting the position information of the photovoltaic glass to be cut to obtain the next cutting point position number, the application considers that with the forward conveying of the photovoltaic glass, a plurality of cutting point positions are successively cut by the cutter head 11, with the continuous cutting work of the cutter head 11 at high temperature, the sharpness of the cutter head 11 will be attenuated, in order to ensure the accuracy of the cutting depth, and at the same time improve the safety and flexibility of the photovoltaic glass cutting operation, the control module 3 is provided with a preset point position number threshold value, if the cutting point position number is greater than or equal to the preset point position number threshold value, the control module 3 corrects the first preset cutter pressure to the second preset cutter pressure, and controls the output cutter pressure of the cutter head 11 according to the second preset cutter pressure, which is equivalent to adding a compensation amount to the first preset cutter pressure after the cutter head 11 completes a certain number of cutting point position operations, so as to ensure the accuracy of the cutting depth.

[0049] As an example, in an embodiment of the application, the marking module 1 marks 20 cutting point positions on the photovoltaic glass to be cut, the control module 3 sets the preset point position number threshold value to 15, the third detection module 7 detects the position information of the photovoltaic glass to be cut to obtain the next cutting point position number, when the third detection module 7 detects that the current photovoltaic glass to be cut has completed 14 cutting point positions, the next cutting point position number is 15, at this time the cutting point position number is equal to the preset point position number threshold value, the control module 3 corrects the first preset cutter pressure to the second preset cutter pressure, and controls the output cutter pressure of the cutter head 11 according to the second preset cutter pressure.

[0050] In the application, the third detection module 7 can be an optical sensor, a laser displacement sensor, an ultrasonic sensor, a vision system, an industrial camera, etc., which is not limited in particular, and can detect the position information of the photovoltaic glass to be cut to obtain the next cutting point position number, so as to compensate and correct the first preset pressure by the control module 3, and improve the safety and flexibility of the photovoltaic glass cutting operation.

[0051] As shown in Figure 1 In some embodiments, a touch display module 8 is further included, the touch display module 8 is in signal connection with the control module 3, the touch display module 8 at least has a first mode and a second mode, in the first mode, the touch display module 8 displays and records the thickness data and the first preset cutter pressure obtained by the control module 3, in the second mode, the touch display module 8 can correct the first preset cutter pressure to the third preset cutter pressure, so that the control module 3 controls the output cutter pressure of the cutter head 11 according to the third preset cutter pressure.

[0052] Specifically, in order to monitor the cutting operation of the to-be-cut photovoltaic glass in real time, facilitate the on-site personnel operation, record and read the data of the pressure control in the subsequent cutting process, and facilitate the pressure control of the tool bit pressure compensation system, the application is provided with a touch display module 8. The touch display module 8 can be a device that can realize touch and display functions, which integrates a display module, an upper computer, an MES (Manufacturing Execution System) system, an EMS (Energy Management System) system, etc., and can realize overall scheduling, process management, parameter control, etc. of the tool bit pressure compensation system.

[0053] The touch display module 8 in the application has at least a first mode and a second mode to cope with different demand scenarios. In the first mode, the touch display module 8 displays and records the thickness data and the first preset tool pressure obtained by the control module 3. In this mode, the touch display module 8 is used to monitor the system state and parameters, and does not directly intervene in the control logic. In the second mode, the touch display module 8 can change the first preset tool pressure to the third preset tool pressure, so that the control module 3 controls the output tool pressure of the tool bit 11 according to the third preset tool pressure. In this way, the operator can adjust the first preset tool pressure according to the actual needs in the cutting operation process to achieve different cutting effects and meet different product quality requirements. The application can set a verification program between the first mode and the second mode to avoid errors caused by accidental touch by the operator.

[0054] In addition, the touch display module 8 of the application can not be limited to the first mode and the second mode, and can be set to multiple different modes. For example, the touch display module 8 can be set to a sentinel mode to monitor and alarm at any time while meeting the monitoring and recording functions; the touch display module 8 can be set to a multi-level permission mode to ensure safety and stability during production; the touch display module 8 can be set to an adaptive adjustment mode, for example, when the output tool pressure differs greatly from the first preset tool pressure or the corrected third preset tool pressure, the output tool pressure can be adaptively adjusted to ensure the smooth progress of the cutting operation. The above examples are only part of the modes that the touch display module 8 has, and the specific configuration is adjusted according to actual production needs, which is not limited here.

[0055] As shown in Figure 1 In some embodiments, it further includes a monitoring module 9, which is signal connected with the second detection module 4 and obtains a plurality of deviation tool pressures of the plurality of output tool pressures and the corresponding plurality of first preset tool pressures, or second preset tool pressures, or third preset tool pressures according to the plurality of output tool pressures, and sends a feedback signal to the control module 3 according to the plurality of deviation tool pressures.

[0056] Specifically, the tool head pressure compensation system of this application also includes a monitoring module 9, which monitors in real time the deviation between the actual output tool pressure of the tool head 11 and different preset tool pressures. When the preset tool pressure is the first preset tool pressure obtained by the control module 3 based on multiple thickness data corresponding to multiple cutting points, the deviation tool pressure is the deviation value between the output tool pressure and the first preset tool pressure. When the preset tool pressure is the second preset tool pressure that is corrected to a cutting point number greater than or equal to a preset point number threshold, the deviation tool pressure is the deviation value between the output tool pressure and the second preset tool pressure. When the preset tool pressure is the third preset tool pressure corrected by the touch display module 8, the deviation tool pressure is the deviation value between the output tool pressure and the third preset tool pressure.

[0057] This application sends a feedback signal to the control module 3 to indicate the deviation in cutting pressure, enabling the control module 3 to adjust the output cutting pressure of the cutter head 11 in a timely manner based on the feedback deviation in cutting pressure. This forms a closed-loop control of the cutting pressure compensation system, thereby ensuring that the cutting pressure of the cutter head 11 is within the ideal control range to improve the consistency and accuracy of the cutting process. Furthermore, continuous deviation detection improves the reliability and stability of the system.

[0058] like Figure 1 As shown, in some embodiments, it further includes: an alarm module 10, which is signal-connected to the monitoring module 9. The alarm module 10 has a preset alarm threshold. If the deviation knife pressure is greater than the preset alarm threshold, the alarm module 10 will sound an alarm.

[0059] Specifically, to further improve the reliability and safety of the cutter head pressure compensation system of this application, an alarm module 10 is also provided. The alarm module 10 is connected to the monitoring module 9 by a signal. The alarm module 10 has a preset alarm threshold. When the actual output cutter pressure of the cutter head 11 detected by the monitoring module 9 is greater than the preset alarm threshold, it can be determined that an abnormality has occurred in the pressure control process of the cutter head pressure compensation system, such as a failure of the drive cylinder of the cutter head 11, an incorrect setting of the first preset pressure, a failure to correct the second preset pressure, or an incorrect input of the third preset pressure. At this time, the alarm module 10 will sound an alarm, which will enable the on-site maintenance personnel to take timely measures to ensure the safe and stable operation of photovoltaic glass cutting.

[0060] like Figure 1 As shown, in some embodiments, the control module 3 has a preset thickness threshold and a preset thickness deviation range. The control module 3 obtains the thickness deviation between the thickness data and the preset thickness threshold based on multiple thickness data. The control module 3 is signal-connected to the alarm module 10. If the deviation thickness exceeds the preset thickness deviation range, the alarm module 10 will sound an alarm.

[0061] Specifically, in order to ensure the safe and stable operation of the photovoltaic glass cutting operation, the application sets a preset thickness threshold and a preset thickness deviation range for the control module 3. The control module 3 obtains the deviation thickness of the thickness data from the preset thickness threshold according to the plurality of thickness data. If the deviation thickness exceeds the preset thickness deviation range, it can be judged that the quality of the to-be-cut photovoltaic glass has a problem, and subsequent operations do not need to consume costs, and can be removed from the production line to ensure the yield of photovoltaic glass production. In order to ensure the safe and stable operation of the cutting operation, the alarm module 10 alarms to notify the on-site operation and maintenance personnel to take timely measures. Moreover, the alarm module 10 can be set to alarm in different modes to help the on-site personnel to distinguish the fault and abnormal situation, such as using different sounds, different lights, etc. as the distinction, which is not limited in particular, and can ensure the safe and stable operation of the cutting operation.
