Abstract

The utility model discloses a novel all-tab cutting, dedusting, winding and kneading integrated production line which comprises two pole piece production lines used for machining positive pole pieces and negative pole pieces respectively, and each pole piece production line comprises a pole piece storage device, a cutting device and a dedusting device. The pole piece storage device and the pole piece which is output by the pole piece storage device and sequentially pass through the cutting device and the dust removal device are arranged, so that the pole pieces output by the dust removal devices of the two pole piece production lines jointly enter the winding device to be overlapped and wound and then are kneaded by the kneading device to be flat, and the full-pole-lug roll core can be output; obviously, because the positive plate and the negative plate are subjected to special cutting and dust removal treatment in the production process, a tab region with a flattened tab and a vacant region with a non-flattened tab can appear at the positive end and the negative end of the full-tab roll core which is finally wound, flattened and output; therefore, through the cutting, dedusting, winding and rubbing integrated production line for the all-tab, integrated production and manufacturing of the all-tab winding core are realized.

Description

Technical Field

[0001] This utility model relates to a production line for processing full-tie tabs, specifically a novel integrated production line for full-tie tab cutting, dust removal, winding, and flattening. Background Technology

[0002] Currently, the manufacturing process of full-tab cores typically requires two electrode production lines. These two lines separately transport the positive and negative electrodes to a winding device for stacking and winding, followed by flattening by a flattening device to output the full-tab core. In this type of full-tab core, both the positive and negative ends have fully flattened tab structures. However, battery manufacturers have designed a more structurally advanced full-tab core with partially flattened tab structures at both the positive and negative ends. This means that both the positive and negative ends of the full-tab core have flattened tab areas and unflattened tab gaps. The purpose is to allow the tab areas to also bear the conductivity of subsequent welding, while the electrolyte can quickly enter the full-tab core through these gaps for injection. Clearly, if this more structurally advanced full-tab core is to be produced, the existing two electrode production lines cannot be directly applied. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a new integrated production line for cutting, dust removal, winding, and flattening all tabs.

[0004] The technical problem of this utility model is solved by the following technical solution:

[0005] A novel integrated production line for cutting, dust removal, winding, and flattening of all electrode tabs includes two electrode production lines for processing positive and negative electrode sheets respectively. Each electrode production line includes an electrode storage device, a cutting device, and a dust removal device, as well as electrode sheets output from the electrode storage device and sequentially passing through the cutting device and the dust removal device. The electrode sheets output from the dust removal devices of the two electrode production lines are jointly fed into a winding device, stacked and wound, and then flattened by a flattening device before being output.

[0006] A correction device for correcting electrode conveying is provided between the electrode storage device and the cutting device.

[0007] The aforementioned correction device and cutting device are provided with a guide wheel for guiding the electrode sheet conveying.

[0008] The cutting device and the winding device are provided with a front guide wheel and a back guide wheel; the dust removal device includes a front dust removal device and a back dust removal device; the front guide wheel guides the electrode sheet to be conveyed so that the front side faces outward, and cooperates with the front dust removal device to form front dust removal of the electrode sheet; the back guide wheel guides the electrode sheet to be conveyed so that the back side faces outward, and cooperates with the back dust removal device to form back dust removal of the electrode sheet.

[0009] The cutting device is a tab laser cutter, which is equipped with a protective gas input component and a dust extraction port component.

[0010] The dust removal device is an ultrasonic dust collector, which is equipped with a vacuum suction component.

[0011] The electrode storage device is an electrode roll, and the electrodes are output sequentially by rotating the electrode roll.

[0012] Compared with the prior art, this utility model mainly modifies two electrode production lines used for processing positive and negative electrode sheets respectively. The specific structure is as follows: each electrode production line includes an electrode storage device, a cutting device, and a dust removal device, as well as electrode sheets output from the electrode storage device and sequentially passing through the cutting and dust removal devices. Then, the electrode sheets output from the dust removal devices of the two electrode production lines are simply fed into the winding device, stacked and wound, and then flattened by the flattening device to output the full-tab core. Obviously, since the positive and negative electrode sheets have undergone special cutting and dust removal treatment during the production process, the full-tab core output after winding and flattening can have flattened tab areas and unflattened tab gap areas at both the positive and negative ends. In this way, the integrated production line of full-tab cutting, dust removal, winding and flattening is used to realize the integrated production and manufacturing of full-tab cores.

[0014] Figure 2 for Figure 1 Top view. Detailed Implementation

[0015] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] A new type of integrated production line for cutting, dust removal, winding, and flattening of all tabs, such as Figure 1 , Figure 2 As shown, the full-tie core is mainly used for integrated manufacturing of structural updates. Through this integrated manufacturing of the full-tie core, both the positive and negative ends can form a partially flattened tab structure. That is, both the positive and negative ends of the full-tie core will have flattened tab areas and unflattened tab gap areas.

[0018] The integrated production line includes two electrode production lines for processing positive and negative electrode sheets, respectively. For example, in this embodiment... Figure 1 As shown, the electrode production lines on the left and right sides of the view can be respectively designated as a positive electrode production line and a negative electrode production line. The two electrode production lines have the same structure. Each electrode production line includes an electrode storage device 1, a cutting device 2, and a dust removal device 3, as well as an electrode 6 output from the electrode storage device 1 and passing through the cutting device 2 and the dust removal device 3 in sequence.

[0019] Therefore, the electrode sheets 6 output from the dust removal devices 3 of the two electrode production lines are simply fed into the winding device 4 for stacking and winding, and then flattened by the flattening device 5 to output the full electrode ear core.

[0020] The electrode storage device 1 is typically an electrode roll, and the electrode roll is used to store the electrode 6. The electrode can be output sequentially by rotating the electrode roll.

[0021] Meanwhile, a correction device 10 for correcting electrode conveying is provided between the electrode storage device 1 and the cutting device 2. This device can be used to prevent the electrode conveying path from deviating and affecting subsequent processes. A guide wheel 7 is provided between the correction device 10 and the cutting device 2 to guide the electrode conveying, and can even guide changes in the electrode conveying direction, such as conveying bends.

[0022] The cutting device 2 is a tab laser cutter, which is usually set above the electrode 6 supported by a pair of guide wheels 7 and transported horizontally. The tab laser cutter needs to be equipped with a protective gas input component 21 and a dust extraction port component 22, which can facilitate rapid cutting and removal of dust, molten metal beads and other materials generated during cutting.

[0023] The cutting device 2 and the winding device 4 are provided with a front guide wheel 8 and a back guide wheel 9; the dust removal device 3 is an ultrasonic dust collector, which is equipped with a vacuum dust collection component. In this embodiment, the dust removal device 3 includes a front dust removal device 31 and a back dust removal device 32.

[0024] During operation, the front guide wheel 8 guides the electrode sheet to be conveyed so that the front side faces outwards, and then cooperates with the front dust removal device 31 to form front dust removal of the electrode sheet; the back guide wheel 9 guides the electrode sheet to be conveyed so that the back side faces outwards, and then cooperates with the back dust removal device 32 to form back dust removal of the electrode sheet; therefore, the front dust removal device 31 and the back dust removal device 32 can completely remove the trace dust and metal beads left on the front and back sides of the electrode sheet by the cutting device 2.

[0025] After the electrode sheet 6 is cleaned by the dust removal device 3 on both sides, it can also be guided and its direction changed by several guide wheels 7, so that the cleaned electrode sheet can smoothly enter the winding device 4.

[0026] In addition, regarding the working purpose of the cutting device 2, it is to expose the positive and negative electrode sheets from both ends of the winding core and form positive and negative electrode tabs. Since the positive and negative electrode tabs have been partially cut by the cutting device 2 beforehand, some of the tabs will be missing at the positive and negative ends after winding into the winding core. This allows the part with the tabs to be flattened to form the tab area, but the part with missing tabs cannot be flattened, thus forming a gap area.

[0027] Therefore, this utility model achieves integrated production of this special-structured full-tab core by performing special cutting and dust removal treatment on the positive and negative electrode sheets during the production process. As a result, the final wound and flattened full-tab core can have flattened electrode areas and unflattened electrode areas at both the positive and negative ends. In this way, the integrated production line for cutting, dust removal, winding and flattening of full-tab cores can be used to achieve integrated production of this special-structured full-tab core.

[0028] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
