Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. 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. The size of power output voltage or electric current can be changed to the magnetic force adjusting device, and then the size of the produced magnetic attraction of change electro-magnet, adjusts the adsorption efficiency of electro-magnet through this kind of mode, promotes application scope.
Of course, according to different product characteristics and processing requirements, the above-mentioned adsorption device 140 that adopts the magnetic attraction of the electromagnet to fix the battery piece can also adopt a combination adsorption mode platform of vacuum adsorption + magnetic attraction, or magnetic attraction and any fixed nature's force in the prior art.
Usually, the battery piece is a coiled material, namely, the battery piece is wound into a material coil through a charging barrel, and the battery piece is gradually sent out in a rotating mode when being supplied. Therefore, in the further technical solution of the present application, the drawing device 100 is a processing platform, and a conventional whole suction type processing platform is designed to be a two-stage structure, the drawing stage 120 is located at the upstream of the cell conveying direction, and the magnetic suction stage is located at the downstream of the cell conveying direction. In addition, the slitting equipment further comprises a traction mechanism 200 and an in-place sensor 300, wherein the traction mechanism 200 is electrically connected with the control device and is arranged on the traction table 120 and used for driving the battery piece to move towards the adsorption device 140, and the in-place sensor 300 is also electrically connected with the control device and is arranged at the tail end of the guide channel. In this way, the battery pieces wound on the material roll are continuously fed downstream under the driving force of the traction mechanism 200, and are adsorbed and fixed on the adsorption device 140, so that the cutting operation can be performed, and the whole processing flow can be reliably and safely completed.
It should be noted that, after long-term frequent operation, the traction mechanism 200 inevitably has a problem of inaccurate driving accuracy. That is, for example, the theoretical conveying distance of the battery piece is set to be 50mm, and the conveying stroke of the traction mechanism 200 for the battery piece is only 48mm when the traction mechanism works actually, which may cause the problem that the cut battery piece unit is scrapped due to the size of the battery piece unit not meeting the product requirement. Based on this, by setting the position sensor 300, the moving distance of the battery piece conveyed onto the adsorption device 140 can be detected and fed back to ensure high feeding accuracy of the battery piece.
With continued reference to fig. 1, in an alternative embodiment, the traction mechanism 200 includes a traction motor 220 and a traction wheel 240 connected to a power shaft of the traction motor 220, wherein the traction wheel 240 is in rolling fit with the battery piece. Therefore, when the traction motor 220 outputs rotating power during operation, the traction wheel 240 rotates synchronously and drives the battery piece to move downstream synchronously through the contact friction force between the wheel surface and the surface of the battery piece, and the feeding operation of the battery piece is completed. The driving mode has the advantages of simple structure, low manufacturing and using cost, no influence on the quality of finished products due to indentation on the surface of the battery piece caused by overlarge pressure, and easy implementation.
It can be understood that, in order to further guarantee reliable traction to the battery piece, the wheel face of the traction wheel 240 can be made into fine structures such as anti-skid grains and array protrusions, so that the contact friction force between the traction wheel 240 and the battery piece is improved, and the problem of skidding is prevented.
It will be appreciated that the traction motor 220 described above may alternatively be any type of motor device known in the art, such as a stepper motor, a servo motor, etc.
Further, the traction mechanism 200 further includes an elastic member (not shown) mounted on the power shaft of the traction motor 220 and elastically connected to the traction wheel 240. Through the setting of elastic component, traction wheel 240 has height (battery piece thickness) self-adaptation ability, not only need not change the prerequisite of the traction wheel 240 of adorning different wheel footpaths under, just can use the roll extrusion pay-off of the battery piece of different thickness to under the effect of elastic force, traction wheel 240 can be the surface of in close contact with battery piece all the time, in order to eliminate installation, manufacturing and cooperation size error.
Furthermore, the table top of the magnetic suction table is provided with two guide convex edges which are arranged at intervals and matched with each other to form a guide channel, and the guide convex edges extend along the conveying direction of the battery piece. The arrangement of the two guide convex edges can prevent the battery piece from deviating in direction when the battery piece moves from the traction table 120 to the magnetic suction table, so that the battery piece unit after being cut is scrapped due to non-compliance.
In addition, with reference to fig. 1, on the basis of any of the above embodiments, the slitting apparatus further includes a slitting mechanism 400, the slitting mechanism 400 includes a cutting knife 420, the traction table 120 and the magnetic attraction table are arranged at an interval and cooperate to form a slit 500, and the cutting knife 420 cooperates with the slit 500. Therefore, after the battery piece is conveyed to the magnetic suction table, the cutter 420 quickly falls down to penetrate through the notch 500, so that the cutting operation of the battery piece can be completed, the notch 500 is guaranteed to be flat and burr-free, and the requirement of processing quality is met.
It should be noted that the cylinder 440 may be a rotary cylinder, a linear cylinder, or the like. In other embodiments, the cutting mode and mechanism in the prior art, such as two cutting blades 420 and a rotary blade, which move relatively, may be adopted to replace the matching structure of the cutting blade 420 and the notch 500, which is also within the protection scope of the present application, and will not be described herein again.
In addition, in the above embodiment, the slitting mechanism 400 further includes an air cylinder 440 electrically connected to the control device, and the cutting blade 420 is connected to a piston rod of the air cylinder 440. The telescopic piston rod of the cylinder 440 can provide stable and sufficient shearing force for the cutter 420, so that efficient and accurate cutting of the battery piece is completed, and the battery piece cutting device is simple in structure and easy to implement.
Of course, according to actual needs, a person skilled in the art may replace the air cylinder 440 with a motor, an oil cylinder, or other power components to provide cutting power for the cutting blade 420.
In another aspect, the present application further provides a battery processing apparatus, which includes the slitting device as described above.
