Example two
The embodiment of the invention provides a rolling thickness adjusting method, which uses the rolling thickness adjusting system of the first embodiment, and comprises the following steps: setting, namely setting a permissible deviation value c of the thickness of the rolled pole piece; and judging, namely when the difference value between the thickness of the rolled pole piece and the specification value is larger than c, adjusting the rolling thickness through an adjusting and controlling module.
Firstly, artificially setting a permissible deviation value c of the thickness of the rolled pole piece. Here c represents the allowable deviation range, and is positive when the rolled pole piece thickness is greater than the specification value, and negative when the rolled pole piece thickness is less than the specification value. For example, the allowable deviation value c of the thickness of the rolled pole piece is set to be-2 to +3 by people, namely the range of the thickness of the rolled pole piece is allowed to be between 2mm below the specification value and 3mm above the specification value. When the thickness of the rolled pole piece exceeds the allowable deviation range, the rolling thickness is adjusted through the adjusting and controlling module.
The calculation module calculates that the difference value between the average thickness of the pole piece on the operation side and the specification value is a1, the difference value between the average thickness of the pole piece in operation and the specification value is a2, the difference value between the average thickness of the pole piece in transmission and the specification value is b1, and the difference value between the average thickness of the pole piece on the transmission side and the specification value is b2. The values of a1, a2, b1 and b2 may be positive or negative, and may be positive when the average thickness of the pole pieces in the corresponding region is greater than the specification value, or negative when the average thickness of the pole pieces in the corresponding region is less than the specification value.
The setting step further comprises setting a difference d allowed by the thickness of the pole piece in the width direction, wherein d is manually set according to the process requirement and represents the difference of the lateral thickness of the pole piece allowed by the process, and d is always a positive value. The artificially set d needs to be always smaller than the absolute value of c, because d is the difference between the allowable lateral thicknesses of the pole pieces and needs to be always smaller than the allowable deviation value of the pole piece thickness after rolling.
In an alternative manner of this embodiment, the judging step further includes an adjusting step. The adjusting step comprises the following steps: when a1 > a2, decreasing the upper bending cylinder pressure of the operation side; when a1 is less than a2 and the absolute value of a1-a2 is more than or equal to d, increasing the upward bending cylinder pressure at the operation side; when a1 < a2 and |a1-a2| < d, increasing the master cylinder pressure on the operation side; when b1 is larger than b2, reducing the upward bending cylinder pressure of the transmission side; when b1 is smaller than b2 and |b1-b2| is larger than or equal to d, increasing the upward bending cylinder pressure at the transmission side; when b1 < b2 and |b1-b2| < d, the master cylinder pressure on the transmission side is increased.
Referring to FIG. 2, when the values of a1, a2, b1, b2 and c are all positive values, the above-mentioned adjusting step is performed if a1 > c or a2 > c or b1 > c or b2 > c. When the values of a1, a2, b1, b2 and c are all negative, the above-mentioned adjustment step is performed if a1 < c or a2 < c or b1 < c or b2 < c.
After the adjusting step is started, if a1 is smaller than a2 and a1-a2 is equal to or larger than d, the condition that the pole piece is thin on the edge, thick in the middle and large in thickness difference after rolling is indicated, and then the pressure of the upper bending cylinder on the operation side needs to be increased. If a1 is less than a2 and |a1-a2| < d, the condition that the pole piece is thin on the edge and thick in the middle after rolling is described, but the thickness difference is in the allowable range, and only the pressure of the master cylinder on the operation side needs to be increased. If a1 > a2, the operating side upper cylinder pressure needs to be reduced. Similarly, if b1 < b2 and |b1-b2|gtoreq.d, the driving side upper bending cylinder pressure needs to be increased. If b1 < b2 and |b1-b2| < d, the master cylinder pressure on the transmission side needs to be increased. If b1 > b2, the driving side bending up cylinder pressure needs to be reduced. The specific numerical value of the pressure adjustment is required to be obtained through verification according to different pole piece processes.
In an alternative manner of this embodiment, the setting step further includes a preparation step before; in the preparation step, a calculation module obtains the production meter number of the pole piece of the roller press and compares the pole piece with the length L of the pole piece between the roller and the thickness gauge, and when the production meter number of the pole piece is larger than L, a setting step is started.
The preparation step is set to start the subsequent closed-loop control when the production meter number of the pole piece is larger than L, so that the closed-loop control is more accurate and effective.
In an alternative manner of this embodiment, the adjusting step further includes an alarm step, and when the number of times of adjustment in the adjusting step exceeds the set number of times, the apparatus automatically alarms and stops.
When the adjusting times of the adjusting step exceeds the set times, the fact that the thickness of the rolled pole piece cannot be effectively adjusted through closed-loop control is indicated, the equipment automatically alarms and stops, and the manual intervention can be timely carried out, so that a great amount of waste of the pole piece is avoided.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
