Based on the above-described tab margin control apparatus, various embodiments of the tab margin control method of the present invention are set forth below.
Referring to fig. 2, fig. 2 is a flowchart of a tab edge distance control method according to an embodiment of the present invention, where the control method according to an embodiment of the present invention may include, but is not limited to, step S100, step S200, step S300, step S400, and step S500.
And S100, acquiring an interrupt signal through a detection module, wherein the interrupt signal represents that a head tab arranged on the material belt is detected.
Specifically, after the last battery cell is manufactured, the detection module is controlled to start positioning detection processing, and meanwhile, the roller conveying module works at a preset first speed. When the detection module detects the first pole lug, the detection module generates an interrupt signal and sends the interrupt signal to the controller, and at the moment, the controller receives the interrupt signal.
In one embodiment, the detection module is controlled to start positioning detection processing, the roller conveying module works at a preset first speed, and if an interrupt signal can be acquired within a set effective detection window range, the detection window range is a preset detection range in the positioning detection processing process, and a set preset fixed interrupt distance is executed; if the interruption signal is not generated or is not in the detection window range, the error is determined, the first tab cannot be detected, the material belt can be considered to have no tab or have other problems in the material belt arrangement, the work is stopped, and the follow-up process does not need to be executed continuously.
In one embodiment, the detection module is influenced by the long scanning period of the detection module in a PLC control mode, the fixed refreshing period of a common IO channel signal is longer, and the scanning period is extremely short and the response time can be prolonged due to the extremely fast response by adopting a driver control mode of a high-speed probe; aiming at the trapezoidal lug, the detection module is arranged at the position with the height of 1/3 of the root part of the lug, so that the positioning error caused by the deviation of the trapezoidal lug and a material line can be effectively reduced, wherein the material line is the position of the lug under the accurate condition of deviation correction setting.
And step S200, controlling the conveying module according to the interrupt signal to enable the first pole lug to move for a preset interrupt distance.
Specifically, after receiving the interrupt signal, the controller immediately controls the roll feeding module according to the interrupt signal, so that the first tab starts to move from the detection position by a preset interrupt distance to reach an interrupt distance end position.
In one embodiment, the detection module is arranged behind the material belt roller conveying direction of the roller conveying module, after the controller receives an interrupt signal sent by the photoelectric module, the roller conveying module is controlled according to the interrupt signal, so that the head tab starts to move from the detection position by a preset interrupt distance, and after the head tab moves by the interrupt distance, the material belt moves from the rear of the material belt roller conveying direction of the roller conveying module to the front of the material belt roller conveying direction of the roller conveying module. Compare through directly walking absolute positioning, send piece position unstable after the material area cuts, the antipodal ear position can't carry out effective control and closed-loop control. In the embodiment, the detection module is additionally arranged to detect the head electrode lug, and the fixed length is taken after the head electrode lug is detected, so that errors caused by a stockline or a mechanical structure in the sheet feeding process can be eliminated.
In an embodiment, referring to fig. 3, after receiving the interrupt signal, the controller may control the roll-feeding module to increase from the first speed (positioning speed) to the second speed (interrupt speed), and after the roll-feeding module operating at the second speed (interrupt speed) drives the leading tab to move for a preset interrupt distance, the controller may control the roll-feeding module to gradually decelerate from the second speed to stop, so as to increase the speed between the interrupt distances, thereby effectively increasing the efficiency. Wherein, EXCUTE represents the positioning processing process, and INFEED represents the process of adjusting the speed of the roll-to-roll module.
It should be noted that the first speed and the second speed are set according to aspects such as actual production time and production process, and the present embodiment does not specifically limit the speed. For example, when seeking an interrupt signal at a first speed, if the detected distance is long, a speed may be set to a larger speed; if the interrupt distance is long, the second speed may be set to a greater speed, which may be determined according to the interrupt distance, and may be set according to the distance that each needs to travel without necessarily having a relationship with the first speed.
In the first embodiment, after receiving the interrupt signal, the controller may not control the speed of the roll feeding module, so that the roll feeding module keeps running at a first speed, and drives the first tab to move a preset interrupt distance, where the first tab refers to a tab that triggers the interrupt signal this time, and may be a first tab of a head portion of a pole piece, a second tab, or a third tab, and this embodiment does not specifically limit the speed.
It should be noted that the interruption distance is set according to the actual process requirement, and this embodiment does not specifically limit the interruption distance.
And step S300, controlling the winding needle module to start, and acquiring the main shaft tracking distance data of the winding needle module.
Specifically, parameters can be set individually for each winding needle module, the controller acquires the winding needle setting parameters, and then establishes a tracking database of the winding needle module corresponding to the winding needle setting parameters in the turntable according to the winding needle setting parameters, wherein the established tracking database is used for acquiring spindle tracking distance data of the winding needle module. And after the interrupt positioning processing is finished, controlling the winding needle module to start, and then acquiring the main shaft tracking distance data of the winding needle module through the tracking database.
It should be noted that the winding needle setting parameter may be data including a winding needle edge distance compensation value, a cathode (or anode) pre-roll length, a cathode (or anode) pre-roll speed, a roll feeding synchronization ratio, a detection start point, a detection terminal, a fixed length of a sensed signal of the cathode (or anode) in a positioning mode, and the like.
It should be noted that the spindle tracking distance data is working data obtained by setting parameters of the winding needle in an actual working process.
And step S400, determining coupling cut-in parameter information of the conveying module and the electronic cam according to the main shaft tracking distance data.
Specifically, after the main shaft tracking distance data of the winding needle module is obtained, coupling cut-in parameter information required for coupling the roller feeding module and the electronic cam can be determined according to the main shaft tracking distance data, the running condition of the roller feeding module and the electronic cam, and the coupling cut-in parameter information is used for enabling the conveying module and the winding needle to achieve the speed and the position to be synchronous.
It should be noted that the electronic cam is a preset electronic cam, and the electronic cam is used for synchronizing the speed and the position of the needle winding module and the roller feeding module, and the specific curve of the electronic cam is set according to the actual situation, which is not specifically limited in this embodiment.
And step S500, coupling the conveying module and the electronic cam according to the coupling cut-in parameter information.
Specifically, the technical scheme of coupling the electronic cam by the roller feeding module has higher efficiency compared with the technical scheme of combining film roller feeding, is not limited by a core winding process, and the scheme of combining film roller feeding is stable in margin but extremely poor in core head X-Ray. The technical scheme of the roller feeding module coupled with the electronic cam can improve the efficiency and the head X-Ray without influencing the stability of the edge distance by the technical scheme of the roller feeding coupled cam synchronization, and the technical scheme of the roller feeding coupled cam synchronization is that the electronic cam is combined with a main shaft offset scheme, which is equivalent to advance coupling, such as: according to the scheme, 3 electronic cam coordinate parameters are set on the touch screen, the set electronic cam track of the roller motor is calculated, the roller motor is subjected to electronic cam coupling when the winding is started, and the purpose of synchronous coupling can be achieved.
And S600, the first tab roller is conveyed into the winding needle module through the conveying module, and the material belt is pre-wound through the conveying module and the winding needle module.
Specifically, after the coupling of accomplishing roller send module and electronic cam is handled, send the module through the roller and send the head utmost point ear roller to send into the suitable position of rolling up the needle module, then send the module through the roller and roll up the needle module and carry out the prewinding processing to the material area, can make the material area can smooth transition after getting into the rolling up needle module, reduce the problem that the skew appears, improve the degree of accuracy.
And step S700, when the pre-winding parameters obtained according to the pre-winding process meet preset conditions, stopping the movement of the conveying module, and winding the material belt through the winding needle module.
Specifically, in the pre-winding process, pre-winding parameters are obtained, when the pre-winding parameters are larger than preset conditions, the conveying module stops rolling after the conveying module and the winding needle module reach speed and position synchronization, pre-winding is completed, then subsequent winding processing is performed on the material belt through the winding needle module, and finally a target battery cell is obtained.
It should be noted that the preset condition includes that the winding of the material tape reaches a preset number of turns in the process of the pre-winding treatment, or that the winding needle module reaches a preset rotation angle in the process of the pre-winding treatment.
It should be noted that the preset number of turns and the preset rotation angle are set according to actual process requirements, and this embodiment does not specifically limit the number of turns and the preset rotation angle.
In an embodiment, referring to fig. 4, when the pre-winding parameter is greater than the preset condition, the conveying module stops rolling after the speed and the position of the conveying module and the winding needle module are synchronized, the pre-winding process is completed, the winding needle module is controlled to increase from the third speed (pre-winding speed) to the fourth speed (winding speed), so that the winding needle module winds the material strip at the fourth speed (winding speed), after the winding process is completed, the winding needle module is controlled to decrease from the fourth speed (winding speed) to the fifth speed (cutting speed), the cutting module is controlled to cut the material strip, and the winding needle module is controlled to stop after the cutting process is completed. The method comprises the steps that an EXCUTE represents the process of winding a material belt by a winding needle module, a CAMIN represents the process of coupling processing of a conveying module and an electronic cam, and a CAMOUT represents the processing processes of respectively adjusting the conveying module and the winding needle module after the coupling processing of the conveying module and the electronic cam is completed.
It should be noted that the third speed, the fourth speed, and the fifth speed are set according to aspects such as actual production time and production process, and the present embodiment does not specifically limit the present invention.
