For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0049] like Figure 1 As shown, an embodiment of the present invention discloses a deviation-correcting micro-sway control device, including: a setting module, a collection module, a control module and an early warning module.

[0050] In some embodiments of the present application, the setting module is used to receive parameter setting instructions sent by a user, and set the micro-swing parameters of the correction micro-swing control device based on the parameter setting instructions; the acquisition module is used to detect the material to be corrected at the corresponding position, and obtain the acquisition value corresponding to the material to be corrected; the control module is used to perform correction control on the correction micro-swing control device according to the relationship between the acquisition value and the preset value; the early warning module is used to obtain the correction status of the material to be corrected, and issue an early warning reminder according to the correction status.

[0051] The beneficial effect of the above technical solution is that the present invention solves the technical problem that when the material to be corrected is wide and the field of view of the CCD camera is insufficient, resulting in insufficient correction accuracy, effectively improves the correction accuracy, and reduces the correction error and production cost.

[0052] In some embodiments of the present application, in the setting module, the micro-swing parameters include micro-swing amplitude, micro-swing speed and stop time.

[0053] In this embodiment, the deviation correction micro-swing control device refers to a motor that performs deviation correction micro-swing operation with a fixed amplitude, a fixed period, and a fixed speed, and can achieve reciprocating motion with a fixed period.

[0054] In this embodiment, the micro-swing amplitude (%) refers to the motor running from the relative position of the sensor (%) to the micro-swing set end point (%).

[0055] In this embodiment, the stop time refers to the stop time when the motor runs to the starting point or the ending point.

[0056] In this embodiment, the micro-swing speed refers to the running speed of the motor when performing the micro-swing action.

[0057] In this embodiment, the parameters contained in the correction micro-swing control device are made into a settable interface for customers to input settings. The input range of each parameter is limited in the software (such as the minimum stop time is 0.01s). When the customer clicks to set the parameter within the touch range, a keyboard will pop up for the customer to enter a preset value. Click ok, and the parameter will be stored in the static storage area. When all four parameters are set, the customer clicks the button to start the micro-swing function, and the parameters will be saved in the ROM (saved when power is off). Click the home button to return to the correction page. If the correction controller is working in manual centering mode at this time, the micro-swing function will not take effect. If the controller is working in automatic mode, the micro-swing function will be turned on.

[0058] In this embodiment, the micro-swing amplitude can be set to 20%, the micro-swing speed can be set to 250, and the stop time can be set to 5s.

[0059] In this embodiment, the micro-sway amplitude=sensor detection range value*0.2.

[0060] In this embodiment, the micro-swing starting point is expressed as a percentage of the full range, such as 50% is represented as the center position of the sensor.

[0061] In this embodiment, the micro-swing end point is expressed as a percentage of the full range, and the motor will swing back and forth between the start point and the end point.

[0062] In this embodiment, the micro-swing speed refers to the running speed. The stop time refers to the pause time after reaching the starting point or the ending point.

[0063] The beneficial effect of the above technical solution is that the present invention can realize intelligent control of deviation correction by setting the micro-swing amplitude, micro-swing speed and stop time in the deviation correction micro-swing control device, thereby ensuring the deviation correction accuracy, and can carry out targeted design according to user needs to improve flexibility.

[0064] In some embodiments of the present application, the acquisition module is specifically used for:

[0065] The acquisition module is used to detect the relative position of the material to be corrected and generate a detection signal according to the relative position;

[0066] The acquisition module is used to determine the corresponding sensor according to the detection signal, and to acquire the acquisition value corresponding to the material to be corrected based on the sensor.

[0067] The beneficial effect of the above technical solution is: by determining the corresponding sensor according to the detection signal, the accuracy of the collected value can be guaranteed, laying a foundation for the correction control of the correction micro-swing control device.

[0068] In some embodiments of the present application, the control module includes:

[0069] A counting unit, for counting from 0 until a preset number is reached;

[0070] A first calculation unit, configured to calculate the sum of the collected value and the micro-swing amplitude when the counting unit starts counting from 0;

[0071] A first control unit, configured to not perform deviation correction control when the sum value is within a blind spot of the deviation correction micro-sway control device;

[0072] A second control unit is used for inputting the sum value into a preset PID controller when the sum value is less than the preset value, converting the sum value into a motor speed based on the PID controller, and performing deviation correction control based on the motor speed;

[0073] The third control unit is used to drive the motor to perform deviation correction control based on the micro-swing speed when the sum value is greater than or equal to the preset value.

[0074] In this embodiment, if the working mode of the deviation-correcting micro-sway control device is the automatic mode and the micro-sway function is turned on, the counting unit starts counting from 0.

[0075] In this embodiment, the blind area is a specific range in which the correction micro-swing control device does not perform correction actions. When the edge position of the material to be corrected is within this range, the correction micro-swing control device will not perform any correction operation, even if a deviation is detected. This design is mainly to prevent the correction micro-swing control device from frequently starting and stopping the correction action when the edge of the material frequently enters and exits the blind area.

[0076] The beneficial effect of the above technical scheme is: the present invention converts the sum value into motor speed or drives the motor for correction control based on the micro-swing speed according to different situations, so as to realize intelligent correction control, solves the technical problem that when the material to be corrected is wide and the field of view of the CCD camera is insufficient, resulting in insufficient correction accuracy, effectively improves the correction accuracy, reduces the correction error and production cost. At the same time, when the sum value is in the blind spot of the correction micro-swing control device, no correction control is performed, which can avoid erroneous correction caused by slight position changes of the material edge in the blind spot, which not only ensures the stability of the correction micro-swing control device, but also ensures the real-time and effectiveness of the correction micro-swing control device.

[0077] In some embodiments of the present application, the control module includes:

[0078] A second calculation unit, used for calculating the difference between the collected value and the micro-swing amplitude when the counting unit reaches a preset number;

[0079] A fourth control unit, configured to not perform deviation correction control when the difference is within a blind area of ​​the deviation correction micro-sway control device;

[0080] a fifth control unit, configured to input the difference into a preset PID controller when the difference is less than the preset value, convert the difference into a motor speed based on the PID controller, and perform deviation correction control based on the motor speed;

[0081] A sixth control unit is used to drive the motor to perform deviation correction control based on the micro-swing speed when the difference is greater than or equal to the preset value.

[0082] In this embodiment, the preset number is 5000 (reaching the stop time set above).

[0083] The beneficial effect of the above technical solution is that the present invention can further ensure the deviation correction control accuracy, improve the deviation correction accuracy, and avoid large errors.

[0084] In some embodiments of the present application, after the counting unit counts to 10,000, the count value is cleared to 0, and continues to increase from 0, executing in a loop to realize the micro-swing function.

[0085] In some embodiments of the present application, the early warning module is specifically used to:

[0086] The early warning module is used to obtain the correction status of the material to be corrected after the correction micro-swing control device corrects the material to be corrected, and judge whether the material to be corrected is successfully corrected according to the correction status.

[0087] If so, no warning reminder will be issued;

[0088] If not, the offset of the material to be corrected is obtained, and different levels of early warning reminders are issued according to the offset.

[0089] In this embodiment, the correction state of the material to be corrected is the basis for judging whether the correction is successful.

[0090] In this embodiment, when obtaining the offset of the material to be corrected, a collection point can be preset on the material to be corrected, and then a reference point can be set. When the collection point and the reference point coincide with each other, it means that the material to be corrected is successfully corrected. When the collection point and the reference point do not coincide with each other, it means that the material to be corrected is not successfully corrected. At this time, the distance between the collection point and the reference point is calculated, and the calculated distance is used as the offset of the material to be corrected.

[0091] The beneficial effect of the above technical solution is that the present invention determines whether the material to be corrected is successfully corrected according to the correction status, and issues an early warning when the correction is not successful, thereby avoiding the phenomenon that the material to be corrected begins to curl before the correction is successful, ensuring product quality and avoiding waste.

[0092] In some embodiments of the present application, the early warning module is specifically used to:

[0093] The early warning module is used to calculate the offset ratio between the offset and a preset offset;

[0094] The warning module is used to set different warning levels according to the offset ratio;

[0095] When the offset ratio is ≥85%, a first-level warning level is set;

[0096] When 65%≤the offset ratio<85%, the second level warning level is set;

[0097] When the offset ratio is less than 65%, a third-level warning level is set;

[0098] Among them, the first-level warning level> the second-level warning level> the third-level warning level.

[0099] The beneficial effect of the above technical solution is that the present invention calculates the offset ratio between the offset and the preset offset, and sets different warning levels according to the offset ratio, thereby achieving targeted warning and taking relevant measures.

[0100] In some embodiments of the present application, it also includes:

[0101] A receiving module, used for receiving a parameter modification instruction from a user;

[0102] a judgment module, used for obtaining the operating state of the deflection-correcting micro-sway control device according to the parameter modification instruction, and when the deflection-correcting micro-sway control device is in the on state, turning off the deflection-correcting micro-sway control device and generating a first modification permission mark; when the deflection-correcting micro-sway control device is in the off state, generating a second modification permission mark;

[0103] An execution module is used to execute the parameter modification instruction according to the first modification permission flag or the second modification permission flag.

[0104] In this embodiment, when the user needs to modify the three parameters of the micro-swing amplitude, the micro-swing speed, and the stop time, a parameter modification instruction is sent.

[0105] In this embodiment, the operating state includes an on state and a off state.

[0106] In this embodiment, the deviation correction micro-swing control device is in the on state, and needs to be turned off before the parameters can be modified, and the micro-swing function can be turned on after confirmation.

[0107] In summary, the embodiment of the present invention discloses a setting module, an acquisition module, a control module and an early warning module. The setting module is used to receive the parameter setting instruction sent by the user, and set the micro-swing parameters of the correction micro-swing control device based on the parameter setting instruction; the acquisition module is used to detect the material to be corrected at the corresponding position, and obtain the acquisition value corresponding to the material to be corrected; the control module is used to perform correction control on the correction micro-swing control device according to the relationship between the acquisition value and the preset value; the early warning module is used to obtain the correction state of the material to be corrected, and issue an early warning reminder according to the correction state.
