As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a battery piece slitting device according to an embodiment of the present application is a main processing unit in a PICI device, and is mainly used for slitting battery pieces, which are raw materials for manufacturing batteries, and the general processing flow is as follows: feeding a battery piece, adsorbing and fixing the battery piece, cutting the battery piece, and grabbing and transferring the cut battery piece.
Specifically, this equipment of cutting includes: the traction device 100 comprises a traction table 120, and is used for carrying out traction conveying on the battery piece; the adsorption device 140 is arranged at the downstream of the traction table 120 and used for fixing the battery piece; and a power supply device 160 electrically connected to the adsorption device 140.
The slitting equipment is mainly used for fixing and slitting the battery pieces as production materials of the batteries. Specifically, in operation, the battery piece is pulled by the pulling platform 120 and conveyed to the suction device 140, and the power supply device 160 supplies power to the suction device 140, so that the suction device 140 can generate enough magnetic attraction to firmly suck and fix the battery piece on the table top. Compare in traditional vacuum adsorption mode, this technical scheme adopts the fixed mode of magnetic attraction can avoid the battery piece to take place to buckle and warp or not hard up, and leads to incision 500 to appear cutting unevenness's problem, guarantees the high quality of cutting of battery piece, and the disability volume is little, promotes product quality and yields.
In an optional embodiment, the slitting equipment further comprises a control device, and the control device can be a PLC device. The adsorption device 140 is an adsorption stage, and specifically, the adsorption stage is an electromagnet. The power supply device 160 includes a power connection and a power supply, one end of the power connection is electrically connected to the electromagnet, the other end of the power connection is electrically connected to the power supply, and the power supply is electrically connected to the control device. Therefore, the electromagnet can generate enough magnetic attraction to firmly adsorb and fix the stainless steel battery piece by outputting electric energy through the power supply, the clamping reliability of the battery piece is high, and the subsequent processing quality is ensured to be good.
Because the battery piece is generally made of metal materials such as stainless steel (in other embodiments, materials such as copper and alloy steel can also be adopted), the adsorption force generated by the adsorption device 140 can act on the surface of the whole battery piece, and then the surface of the battery piece can be firmly adsorbed and attached to the surface of the platform, so that the shape of the battery piece which is subjected to bending deformation can be corrected, further warping deformation of the battery piece can be prevented, loosening of the battery piece due to insufficient adsorption force can be effectively prevented, the cut 500 is ensured to be flat and smooth, and the quality of the cut battery piece unit meets the production requirement.
It should be noted that, in order to effectively fix the battery piece and prevent the battery piece from bending and warping due to stress, the surface of the electromagnet should be precisely milled or cut, for example, a high-precision numerical control machine or a machining center is used to ensure the flatness of the surface of the electromagnet to be high, thereby providing a reliable basis for high-quality machining of the battery piece.
Moreover, the required fixing adsorption force is different for battery plates with different sizes, types and materials. Therefore, in order to flexibly adjust the magnetic attraction of the battery iron and achieve the capability of being suitable for different adsorption objects, the slitting equipment further comprises a magnetic force adjusting device, and the magnetic force adjusting device is electrically connected with the power supply device 160.
