Embodiment 1
[0030] Embodiment 1: A device for removing burrs during the processing of lithium-ion battery pole pieces, see Figure 1 to Figure 8 , comprising a fixed shaft 5, at least two pull-out units are set on the fixed shaft 5, the pull-out unit includes a swing rod 7 with the fixed shaft 5 as a fulcrum, the other end of the swing rod 7 is equipped with a pull-out mechanism, and the pull-out mechanism includes oppositely arranged connections. The rubber roller 2 of the power source is provided with a thread 10 on the rubber roller 2. The direction of rotation of the thread 10 is the same as that of the rubber roller 2. The spacing of the thread 10 between the rubber rollers 2 corresponds to the width of the battery pole piece 11 to be processed. Rubber roller 2 is made of flexible material, and its bottom end matches with transmission belt 9, and the input end of transmission belt 9 is connected with motor 3, and the diameter of rubber roller 2 decreases progressively from bottom end ...

The invention relates to a burr removal device and method of a lithium ion battery pole plate during processing. The invention aims to solve the problem of difficulty in burr processing during processing of the lithium ion battery pole plate in the prior art. The burr removal device comprises a fixed shaft, wherein at least two removal units sleeve the fixed shaft, each removal unit comprises a swinging rod, the swinging rod takes the fixed shaft as a support point, a removal mechanism is arranged at the other end of the swinging rod and comprises rubber rollers, the rubber rollers are arranged opposite to each other and are connected with a power source, threads are arranged on the rubber rollers, rotation directions of the threads are the same as the rotation directions of the rubber rollers, and the distance of the threads between the rubber rollers are corresponding to the width of the battery pole plate. By the burr removal device, continuous production of the pole plate can be achieved, the finished product is high in quality, the burr removal effect is good, and a potential risk is low.
Description
technical field [0001] The invention relates to the field of lithium ion battery manufacturing, in particular to a device and method for removing burrs during the processing of lithium ion battery pole pieces. Background technique [0002] With the wide application of 3C products (notebooks, smart phones, digital cameras), electric vehicles, and large-scale construction of energy storage power stations, the lithium-ion battery market is also steadily expanding year by year, and it is expected that the market size will exceed that of lead-acid batteries in 2018 . [0003] At present, in the manufacture of lithium-ion batteries, when cutting battery pole pieces, due to the deviation of the alignment angle of the upper and lower blades of the slitting machine or the wear of the blades, burrs are easily generated at the cutting place. When the length of the burr is longer than the thickness of the separator, it is very easy to pierce the separator, causing a short circuit betwe...
