Description
Technical Field
The invention relates to the technical field of automatic plugging sheets of winding machines, in particular to a device for preventing an electric core from deforming by an automatic plugging sheet.
Background
The shape of the lithium battery on the market is not two, namely a cylindrical shape, a square shape, and a square shape lithium battery, because the winding needle is square, the winding tension is difficult to ensure constant in the winding process, and the diaphragm in the raw material of the winding core has the natural characteristics of post-process heating shrinkage and the graphite on the other raw material pole piece heating expansion in the post-process, so after the battery core is wound, the battery core deformation can occur in the post-process until the finished product process, thereby causing the battery core scrapping loss, and the battery core winding cannot be controlled by the industry all the time. The existing winding machine solves the problems that the winding speed is changed along with the change of the angle of a winding needle in the winding process, the winding process is close to constant tension, but the process control is complex, the process is difficult to accurately control, the cost is increased too high, the effect is not obvious, the current industry practice is to want a method from the winding machine, the wound battery core is clamped through tension control and want a method in a later process, the heating, the pressurizing and the powerful shaping are carried out, but the spring still can rebound, and the two methods still cannot stop the battery core from deforming.
Disclosure of Invention
In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides an automatic inserting piece prevents device that electric core warp, includes specification piece, spool, roll up the axle sleeve, the inserting piece draws the piece, the inserting piece cylinder, the bottom plate, inserting piece slider seat and cylinder rail connection piece, surface mounting has the guide rail on the bottom plate both sides, the inserting piece slider seat is installed to the guide rail slider on the guide rail, the inserting piece draws the piece to be fixed in above the inserting piece slider seat, the inserting piece draws the piece to connect in the one end of spool, drives spool fore-and-aft motion, the spool dress is in the spool cover, the specification piece is installed in the spool front end, along with spool fore-and-aft motion, the inserting piece cylinder is connected through cylinder rail connection piece to the guide rail slider, the inserting piece cylinder passes through PLC system control.
Compared with the prior art, the invention has the beneficial effects that: the invention combines a PLC control system, realizes the function of automatically inserting a specification sheet at a specified number of turns in the winding process of the square lithium battery core, and automatically drawing out the specification sheet after the winding is completed, thereby leaving a space with the size of the specification sheet in the square lithium battery core, and the space can absorb the deformation in the lithium battery core in the subsequent working procedure, thereby solving the problem that the deformation is transmitted to the outside of the lithium battery core to cause bad appearance distortion.
