Embodiment Construction
[0034] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0035] First, take the lithium battery winding machine as an example to explain the winding machine. Specifically, the winding machine rolls a large area of sheet-like material into a roll according to a certain plan, and the lithium battery winding machine is used to wind the lithium battery. battery cell. The lithium battery winding machine installs the positive and negative electrode sheets and diaphragm material rolls with lugs welded on the fixing device, performs unwinding, deviation correction, winding, output cells, etc., and completes the winding of lithium batteries and the production of cells and other steps.
[0036] A common lithium battery winding machine usually consists of a frame, a winding device, a diaphragm supply part, a pole piece supply part, an auxiliary pressure roller an...

The application provides an unwinding speed control method, device, electronic equipment and storage medium, and relates to the technical field of winding equipment control. The method includes: determining the running state of the winding machine; determining a target parameter that needs to be synchronized based on the running state, and the target parameter includes the speed of a length-counting encoder, the speed of a virtual servo shaft or the speed of a sheet feeding motor; based on the target The current parameter value of the parameter regulates the controlled shaft speed of the winder. The method determines the speed of the controlled shaft by following the speed value of the length-counting encoder, virtual servo shaft or sheet-feeding motor based on the running state of the winding machine, and synchronizes with the matching target parameters under different running states, thereby improving the winding speed. Machine unwinding accuracy.
Description
technical field [0001] The present application relates to the technical field of winding equipment control, in particular, to a method, device, electronic equipment and storage medium for controlling the unwinding speed. Background technique [0002] The winding machine is to roll a large-area sheet material into a roll according to a certain plan, such as a textile winding machine, a capacitor winding machine, a film resistance winding machine, a battery winding machine, etc. The capacitor winding machine is to wind the capacitor film, aluminum foil or pole pieces together according to the designed combination to form the capacitor core. It is the key equipment for capacitor manufacturing, and the film capacitor manual workshop is basically a winding machine. Lithium battery winding machine is used to wind lithium battery cells. [0003] However, the winding speed control of the current winding machine is usually controlled by the programmable controller according to the ...
