Description

Technical Field

[0001] The invention relates to the technical field of battery pole piece processing, and in particular to pole piece rolling and stretching equipment for composite current collector processing. Background Art

[0002] The composite current collector is a new type of battery material with a three-layer composite structure of "metal-polymer material-metal". The outer layer of the composite current collector is usually composed of copper metal or aluminum metal, which are used for the negative and positive current collectors of the battery respectively. For example, in lithium-ion batteries, copper foil is used as the negative current collector and aluminum foil is used as the positive current collector. In the composite current collector, these metal layers play the role of collecting and transmitting current. The middle layer is a base film of polymer material. Common materials include PET (polyethylene terephthalate), PP (polypropylene) or PI (polyimide). These polymer materials have good insulation, flexibility and mechanical strength, which can provide support and protection for the composite current collector, and also reduce the weight of the current collector.

It can improve the performance and quality of the pole piece through the rolling and stretching process. The existing device does not clean the pole piece surface when rolling the pole piece. When there are some small particles adhering to the pole piece, the pole piece will be squeezed due to the small particles, which will cause the density inside the pole piece to be inconsistent during rolling, and will also cause the pole piece's performance in conductivity and storage of electricity to deteriorate.

One end of the threaded rod 56 is fixedly connected to the knob 57. When the pole piece passes through the guide part When the component 5 is subsequently rolled, due to the different widths of the pole pieces, it is necessary to limit the two sides of the pole piece against each other when rolling the pole piece, so as to avoid the pole piece becoming thinner than the original thickness when rolling the pole piece, and at the same time making the pole piece wider, resulting in different thicknesses on both sides of the pole piece. When the pole piece passes through the guide component 5, by rotating the knob 57, the knob 57 drives the threaded rod 56 to rotate on the inner side of the guide shaft 51, so that the threaded rod 56 drives the two sliders 55 to move in the opposite direction, so that the slider 55 drives the connecting sleeve 54 to move in the sliding groove 52, so that the size of the processed pole piece width is used to appropriately adjust the position of the connecting sleeve 54 for movement.

[0039] Example 3, using Figure 1-Figure 9 The pole piece rolling and stretching equipment for composite current collector processing of the present invention is described as follows:

[0040] like Figure 7-Figure 9 It is shown that a pole piece rolling and stretching device for composite current collector processing of the present invention is based on the first embodiment;

[0041] The contact component 8 includes a contact shell 81, both sides of the contact shell 81 are fixedly connected to the inner side of the fixed shell 4, a contact groove 82 is opened on the inner side of the contact shell 81, and through holes 83 are evenly opened on the side of the contact groove 82, the inner side of the contact groove 82 is rotatably connected to a contact roller 84, and the side of the contact groove 82 away from the contact roller 84 is rotatably connected to a cleaning mechanism 85; when the rolling component 9 rolls the pole piece, in order to avoid impurities adhering to the roller shaft in the rolling component 9 when the rolling component 9 rolls the pole piece, the impurities on the roller shaft will be squeezed into the pole piece when the pole piece is rolled, and at the same time, when the roller shaft in the rolling component 9 rolls, the side of the roller shaft can be cleaned by the cleaning mechanism 85, and the cleaned roller can be wiped by the contact roller 84, so as to avoid the side of the roller shaft from adhering to external impurities, which will interfere with the rolling work of the pole piece.

[0042] The cleaning mechanism 85 includes a cleaning roller 851, both sides of which are rotatably connected to the inner side of the contact groove 82, and the sides of the cleaning roller 851 are evenly provided with clearance grooves 852, and the inner side of the clearance groove 852 is slidably connected with a sliding rod 853, and the end of the sliding rod 853 away from the clearance groove 852 is fixedly connected to a fixed plate 854, and both sides of the fixed plate 854 are fixedly connected with a scraper 855, and a second spring 856 is sleeved on the sliding rod 853, and one end of the second spring 856 is fixedly connected to the inner side of the clearance groove 852, and the other end of the second spring 856 is fixedly connected to the fixed plate 854; when the roller shaft in the rolling component 9 rotates, the roller shaft The scraper 855 performs cleaning contact work, so that the scraper 855 can clean and drop the impurities attached to the roller shaft, and at the same time avoid excessive extrusion pressure between the scraper 855 and the roller shaft. By evenly opening a yield groove 852 on the side of the cleaning roller 851, when the extrusion pressure between the impurities on the roller shaft and the scraper 855 is too large, the scraper 855 can drive the sliding rod 853 to move in the yield groove 852 through the fixed plate 854, and at the same time, through the buffering extrusion work of the second spring 856, it is avoided that the extrusion pressure between the scraper 855 and the impurities is too large, which will leave scratches on the side of the roller shaft, thereby interfering with the subsequent pole piece rolling work.

[0043] The specific workflow is as follows:

[0044] During operation, after one end of the pole piece sleeved on the unloading component 2 is wound and fixed with the winding component 3, the pole piece is driven to move by the winding component 3, and the pole piece to be rolled is cleaned by the unloading component 2. At the same time, after the guide component 5 performs appropriate adjustment according to the corresponding pole piece, the pole piece is rolled by the rolling component 9, so that the winding component 3 collects the pole piece after the rolling work. At the same time, when the rolling component 9 rolls the pole piece, the rolling component 9 and the contact component 8 are contacted and rotated, so that the side of the rolling component 9 is contacted and cleaned by the contact component 8;

[0045] When the pole piece wound on the unwinding component 2 passes through the adjusting frame 61, the small motor 62 is turned on, and the output end of the small motor 62 drives the screw rod 63 to rotate inside the adjusting frame 61, so that the two extrusion mechanisms 64 move relative to each other, so that the corresponding adjustment work can be performed according to the pole piece passing through the adjusting frame 61, so that the extrusion mechanism 64 and the pole piece move against each other;

[0046] When the pole piece continues to pass through the adjustment frame 61, the roller 642 first contacts the pole piece, so that the roller 642 guides the pole piece passing through the inner side of the adjustment frame 61. At the same time, when the pole piece contacts the rotating assembly 643, the rotating assembly 643 can clean the pole piece, so as to prevent some small particles from adhering to the pole piece.

[0047] When the pole piece passes, the pole piece and the bent plate 6435 are in contact and cleaned, so that the bent plate 6435 can drive the rotating shaft 6431 to rotate inside the adjusting frame 61, so that the bent plate 6435 can clean the inside of the pole piece. At the same time, a rubber plate 6436 is fixedly connected to the side of the connecting plate 6433 away from the bent plate 6435. When the bent plate 6435 cleans the pole piece, the impurities protruding from the pole piece can enter the cavity between the bent plate 6435 and the rubber plate 6436, thereby preventing the impurities scraped off by the bent plate 6435 from remaining on the pole piece, and preventing the pole piece surface from being uneven during the subsequent rolling work on the pole piece.

[0048] When the pole piece passes through the guide component 5 for subsequent rolling work, due to the different widths of the pole piece, it is necessary to limit the two sides of the pole piece against each other when rolling the pole piece, so as to avoid the pole piece becoming thinner from the original thickness when rolling the pole piece, and at the same time making the pole piece wider, resulting in different thicknesses on both sides of the pole piece. When the pole piece passes through the guide component 5, by rotating the knob 57, the knob 57 drives the threaded rod 56 to rotate inside the guide shaft 51, so that the threaded rod 56 drives the two sliders 55 to move in the opposite direction, so that the slider 55 drives the connecting sleeve 54 to move in the sliding groove 52, so that the size of the processed pole piece width is appropriately adjusted to move the position of the connecting sleeve 54;

[0049] After the rolling component 9 performs rolling work on the pole piece, in order to prevent the roller shaft in the rolling component 9 from being adhered to impurities when the rolling component 9 performs rolling work on the pole piece, and then when the pole piece is rolled, the impurities on the roller shaft will be squeezed into the pole piece, and at the same time, when the roller shaft in the rolling component 9 performs rolling work, the side of the roller shaft can be cleaned by the cleaning mechanism 85, and the cleaned roller shaft can be wiped by the contact roller 84, so as to prevent the side of the roller shaft from being adhered to foreign impurities, and then interfere with the rolling work of the pole piece;

[0050] When the roller in the rolling component 9 rotates, the roller and the scraper 855 perform cleaning contact work, so that the scraper 855 can clean and drop the impurities attached to the roller, and at the same time avoid excessive extrusion pressure between the scraper 855 and the roller. By evenly opening a clearance groove 852 on the side of the cleaning roller 851, when the extrusion pressure between the impurities on the roller and the scraper 855 is too large, the scraper 855 can drive the sliding rod 853 to move in the clearance groove 852 through the fixed plate 854, and at the same time, through the buffering extrusion work of the second spring 856, it is avoided that the extrusion pressure between the scraper 855 and the impurities is too large, which will leave scratches on the side of the roller, thereby interfering with the subsequent pole piece rolling work.

[0051] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
