[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Please refer to Figure 1 , Figure 1 A flowchart of a positioning method based on a correction controller provided in an embodiment of the present application. The positioning method based on a correction controller in an embodiment of the present application can be applied to a correction controller on a coil production device, wherein the correction controller is connected to a first correction sensor, a second correction sensor and a correction actuator. Figure 2 The functional structure diagram of the locator shown in the figure shows that the correction controller is connected to the extension module, which is connected to the two-way moving modules (i.e. the slider M1 where the first correction sensor is located and the slider M2 where the second correction controller is located), and the execution module of the locator is the correction actuator. The extension module has a built-in MCU and a two-way click drive circuit, and a single-way module or a dual-way module can be selected according to actual needs. In addition to supporting the drive motor, the extension module also supports the transparent transmission of sensor signals to the correction controller. The correction controller only needs to connect the extension module to drive the locator and obtain the analog signal of the sensor.

[0045] like Figure 1 As shown, the positioning method based on the deviation correction controller of this embodiment includes steps S101 to S104, which are described in detail as follows:

[0046] Step S101, obtaining target configuration parameters, where the target configuration parameters include parameters regarding the position relationship between the first deviation correcting sensor and the second deviation correcting sensor.

[0047] In this step, the deviation correction sensor can be a photoelectric sensor or an ultrasonic sensor. Figure 3 As shown, the correction sensor is arranged on the slider 4, and the correction actuator 1 (which can be a motor) drives the pulley 2 to drive the screw component 5 to rotate, so as to transmit the correction sensor to move, and the limit sensor 3 limits the slider 4. Figure 4As shown, the first deflection correction sensor is installed on the slider M1, and the second deflection correction sensor is installed on the slider M2. The target configuration parameters include but are not limited to the minimum width, maximum width and center point position between the first deflection correction sensor and the second deflection correction sensor, as well as the working pulse of the deflection correction actuator, among which the minimum width, maximum width and center point position are position relationship parameters.

[0048] Optionally, the target configuration parameters are measured after installing the correction sensor, so as to be called in the real-time process of correction positioning; the zero point position is a limit sensor, and the target configuration parameters control the movement of the limit sensor to set the zero point position, so as to configure the target configuration parameters in real time, thereby meeting the correction positioning needs of various application conditions.

[0049] Step S102, based on a preset automatic travel strategy, determining a correlation between the target configuration parameter and the travel pulse count of the deviation correction actuator.

[0050] In this step, the preset automatic travel strategy is to configure the working pulses of the correction actuator corresponding to different positions of the correction sensor to realize the automatic control of the movement of the correction sensor. The correlation between the target configuration parameters and the stroke pulse count of the correction actuator is actually the control relationship between the correction actuator and the first correction sensor and the second correction sensor. The stroke pulse count is the driving control amount of the correction actuator driving the first correction sensor or the second correction sensor. Optionally, a preset automatic travel function is used to configure the correlation between the target configuration parameters and the stroke pulse count of the correction actuator.

[0051] Step S103, in response to the target positioning instruction, determining a target stroke pulse count corresponding to a target position parameter based on the association relationship, wherein the target position parameter is a position parameter carried in the target positioning instruction or a position parameter determined based on the target positioning instruction.

[0052] In this step, the target positioning instruction is a positioning instruction initiated by the user through the operation interface, including but not limited to automatic edge-finding positioning instructions, fine-tuning positioning instructions and manual positioning instructions. The automatic edge-finding positioning instruction is an instruction to automatically find the edge of the coil and adjust the position of the correction sensor according to the coil edge; the fine-tuning positioning instruction is an instruction to control the correction sensor to move with a preset displacement when the coil width is unknown or the coil width is incorrect; the manual positioning instruction is an instruction to control the correction sensor to move with a displacement input by the user when the coil width is known.

[0053] By means of the correspondence between the position parameters of the first and second deflection correction sensors and the stroke pulse counts of the deflection correction actuator in the association relationship, the target stroke pulse counts corresponding to the position parameters corresponding to the target positioning execution are determined, thereby achieving accurate quantification of the displacement control amounts of the first and second deflection correction sensors, and further realizing the deflection correction positioning of the deflection correction sensors by the deflection correction controller.

[0054] Step S104: Based on the target stroke pulse count, controlling the correcting actuator to adjust the position of the first correcting sensor and / or the second correcting sensor.

[0055] In this step, the target stroke pulse count includes the first stroke pulse count corresponding to the first correcting sensor and the second stroke pulse count corresponding to the second correcting sensor. Based on the first stroke pulse count, the correcting actuator is controlled to adjust the position of the first correcting sensor, and based on the second stroke pulse count, the correcting actuator is controlled to adjust the position of the second correcting sensor.

[0056] This embodiment determines the correlation between the target configuration parameters and the stroke pulse count to obtain the control amount of the correction actuator on the first correction sensor and the second correction sensor, so that when obtaining the target positioning instruction, the actual control amount of the correction actuator on the first correction sensor and the second correction sensor can be determined according to the correlation relationship, and the correction actuator adjusts the position of the first correction sensor and the second correction sensor, and realizes the positioning of the correction sensor by the correction controller in the form of software program without adding hardware, thereby realizing the locator function of the correction controller at a low cost.

[0057] In some embodiments, the step S102 includes:

[0058] Based on the first automatic stroke function, determining a first correlation relationship between the position of the first deviation correction sensor and the stroke pulse count according to the maximum distance parameter, the minimum distance parameter and the position center parameter;

[0059] Based on the second automatic travel function, a second correlation relationship between the position of the first deviation correction sensor and the travel pulse count is determined according to the maximum distance parameter, the minimum distance parameter and the position center parameter.

[0060] In this embodiment, if Figure 4 As shown, the maximum distance parameter is "maximum width", the minimum distance parameter is "minimum width", and the position center parameter is "center offset value". The stroke pulse count includes the first stroke pulse count Lpls when the M1 sensor moves from the maximum width to the minimum width and the second stroke pulse count Rpls when the M2 sensor moves from the maximum width to the minimum width.

[0061] Optionally, the expression of the first automatic travel function is:

[0062]

[0063] The expression of the second automatic travel function is:

[0064]

[0065] Wherein, Ldtl represents the first association relationship, Rdtl represents the second association relationship, S max is the maximum distance parameter, S min is the minimum distance parameter, Coff is the position center parameter, Lpls represents the first stroke pulse count, and Rpls represents the second stroke pulse count.

[0066] This embodiment uses the first automatic stroke function and the second automatic stroke function to automatically obtain the control amount of the correction actuator on the correction sensor, so as to facilitate the subsequent correction positioning.

[0067] In some embodiments, the step S103 includes:

[0068] In response to the automatic edge finding and positioning instruction, determining the positional relationship between the coil on the coil production equipment and the first and second deflection correcting sensors;

[0069] If the positional relationship is that the web blocks the first deflection correcting sensor and / or the second deflection correcting sensor, a first target position parameter of the first deflection correcting sensor and / or the second deflection correcting sensor away from the web is generated, and based on the association relationship, a target stroke pulse count corresponding to the first target position parameter is determined;

[0070] If the position relationship is that the web does not block the first skewing sensor and / or the second skewing sensor, and the distance between the web and the first skewing sensor and / or the second skewing sensor is greater than a preset value, a second target position parameter of the first skewing sensor and / or the second skewing sensor close to the web direction is generated, and based on the association relationship, the target travel pulse count corresponding to the second target position parameter is determined.

[0071] In this embodiment, if Figure 5 As shown in the operating interface schematic diagram, button "A" is the initiation button for the automatic edge-finding and positioning instruction. The user clicks button "A" through the operating interface to trigger the automatic edge-finding and positioning instruction. The correction controller responds to the automatic edge-finding and positioning instruction, determines the boundary of the coil and adjusts the position of the correction sensor through a cycle until the coil is in the middle of the first correction sensor and the second correction sensor.

[0072] Specifically, the positional relationship between the first skew correction sensor, the second skew correction sensor and the web is determined through a skewing sensor or a visual sensor. If the web is located exactly in the middle between the first skewing sensor and the second skewing sensor, there is no need to adjust the position. If the web blocks the first skewing sensor and / or the second skewing sensor, it means that the first skewing sensor and / or the second skewing sensor are within the range of the web, so the first skewing sensor and / or the second skewing sensor are moved away from the web (i.e., backward), and a first target position parameter is generated. If the web does not block the first skewing sensor and / or the second skewing sensor, and the distance between the web and the first skewing sensor and / or the second skewing sensor is greater than a preset value (the preset value can be 0), it means that the first skewing sensor and / or the second skewing sensor are far away from the web position, so the first skewing sensor and / or the second skewing sensor are moved toward the direction close to the web (i.e., forward), and a second target position parameter is generated.

[0073] Optionally, the positional relationship between the sensor and the coil can be represented by an analog quantity, for example 0 to 3.000V. When the coil completely blocks the sensor, the analog quantity is 0V, when it is completely unblocked, the analog quantity is 3.000V, and when the coil is exactly in the middle of the two sensors, the analog quantity is 1.500V.

[0074] In some embodiments, after step S104, the following steps are further included:

[0075] Return to the step of determining the positional relationship between the coil on the coil production equipment and the first and second skew correcting sensors, and determine a new target stroke pulse count until the coil is exactly in the middle of the first and second skew correcting sensors to complete positioning.

[0076] In this embodiment, the position of the deviation correction sensor is adjusted by cyclic edge finding so that the coil is located in the middle of the two deviation correction sensors, thereby achieving fully automatic edge finding and positioning.

[0077] In some other embodiments, the target positioning instruction is a fine-tuning positioning instruction, and the step S103 includes:

[0078] In response to the fine-tuning positioning instruction, based on the association relationship, the target stroke pulse count corresponding to the target position parameter is determined, the target position parameter is a preset sensor displacement parameter called when the user clicks the fine-tuning button to trigger the fine-tuning positioning instruction, the fine-tuning button is a left fine-tuning button or a right fine-tuning button, and the preset sensor parameter is the preset displacement parameter of the first correction sensor or the preset displacement parameter of the second correction sensor.

[0079] In this embodiment, if Figure 5As shown in the figure, the "←" key indicates a left shift operation, the "→" key indicates a right shift operation, and the "0" key indicates a zero return operation, that is, the sensor returns to the zero position. The user can click the "←" key or the "→" key to initiate a left fine-tuning positioning command or a right fine-tuning positioning command according to the preset moving step length, wherein the first or second deflection correction sensor can be selected by clicking the "M1" key or the "M2 key", and then the "←" key or the "→" key can be used to perform a fine-tuning positioning operation on the first or second deflection correction sensor.

[0080] In some other embodiments, the target positioning instruction is a manual positioning instruction, and the step S103 includes:

[0081] In response to the manual positioning instruction, based on the association relationship, the target stroke pulse count corresponding to the target position parameter is determined, and the target position parameter is a displacement parameter of the first correcting sensor or a displacement parameter of the second correcting sensor input by the user in real time.

[0082] In this embodiment, if Figure 5 As shown, the key "M" is the initiation key of the manual positioning command, and the user can manually set the width value (such as Figure 5 800.00mm), then click the "M" button to trigger the manual positioning command.
