Description

Technical Field

[0001] The utility model relates to the technical field of battery core production, and in particular to a battery core winding, flat pressing and gluing device. Background Art

[0002] The battery cell winding process is a traditional manufacturing process. The battery cell molding preparation pretreatment can be completed by winding different electrode sheets into a plate shape and then extruding and shaping. The traditional manufacturing process is bare cell winding → flat pressure Hi-pot measurement → bare cell heating → cold pressing and shaping → flat pressing and gluing → bare cell cutting.

[0003] For the subsequent battery cell forming process, it is necessary to post adhesive strips on both ends of the battery cell for fixation. There will be gaps on the flat press plate, and the hardness of the battery cell roll is low. During the flat press process, the edges of the battery cell roll at both ends are prone to warping, which seriously affects the test result. In the gluing process, manual gluing is performed on the flat press plate, which is inefficient and of low quality. Subsequent hot and cold treatments lead to a decrease in the yield rate, which is not conducive to mass production. At the same time, since the flat press plates are mostly controlled mechanically, manual placement of the wound battery cells is very likely to cause safety accidents. Utility Model Content

[0018] The beneficial effects of the utility model are as follows: the utility model is a battery cell winding flat pressing glue pasting device which effectively prevents the battery cell from being flattened and curled, reduces the difficulty of gluing, and safely feeds the wound battery cell material. The specific implementation method is as follows:

[0019] The operator first moves the opening of the push block away from the flat pressing mechanism, then pulls the handle bar away from the middle of the push block, moves the cross bar to drive the rotating clamping block to twist the torsion spring, expands the rotating clamping block outward, places the battery core material between the rotating clamping blocks, then releases the handle bar to move it closer to the middle of the push block, clamps the battery core, then flips the push block, uses the push sliding groove to send the battery core into the middle of the flat pressing mechanism, and then continues to pull the handle bar away from the middle of the push block to complete the battery core feeding, then starts the second cylinder to make the push plate abut against the winding battery core to complete the preparation work, and the limit transverse rod can prevent the rubber roller on the roller support rod from rotating between the pressure plate parts to avoid unsmooth feeding;

[0020] Then start the first cylinder to drive the circular movable rod to leave the horizontal slide groove and stay in the oblique slide groove. The circular movable rod squeezes the recovery spring toward the top edge slider. At the same time, guided by the oblique slide groove, the two sets of pressure plates are brought together and the wound battery cell is flattened to measure and record the resistance value. At the same time, the rotating film of the wound rubber strip is fixed on the equipment on both sides of the top edge slider of the wound battery cell. Since this method is a prior art and does not belong to the utility model point of the present utility model, it will not be repeated here. After manually passing one end of the rubber strip through the glue roller and the horizontal cutting knife, the top edge slider below is squeezed to fit it to the lower surface of the wound battery cell.

[0021] After the test is completed, the first cylinder is started to contract, driving the circular movable rod away from the fixed plate and driving the limit plate to move to the fixed plate. After the limit plate continues to drive the circular movable rod to move out of the oblique slide groove to the transverse slide groove, the meshing gear on the circular movable rod meshes with the double-sided rack rod, driving the circular movable rod to rotate. While the circular movable rod rotates, it continues to drive the first pressure plate and the second pressure plate to flip outward, so that the first pressure plate is separated from the second pressure plate, and the top edge slider and the folding plate continue to be connected to the first pressure plate by the circular protrusion in the circular through groove. During the movement of the circular movable rod to the outer end of the transverse slide groove, the contact rod gradually separates from the moving support rod and slides onto the oblique folding part, and the lifting and unloading plate is driven by the gravity of the second cylinder. The movable lifting and unloading plate descends along the guiding direction of the dovetail protrusion, driving the winding battery core clamped by the pushing plate on the second cylinder to descend, and the winding battery core pulls the rubber strip to extend. At the same time, the rubber strip on the side is driven by the torsion of the torsion spring on the roller support rod to squeeze and fit the winding battery core, completing the side gluing of the first group of winding battery cores. After that, the first cylinder is continued to be started to extend, driving the circumferential movable rods at both ends to move together, and at the same time restoring the splicing state of the pressing plate parts, that is, the rectangular protrusion of the top edge slider on the first pressing plate continues to be inserted into the rectangular opening groove, and at the same time, the movable sliding groove on the linkage plate can prevent action interference, and the contact rod on the oblique folding part drives the lifting and unloading plate to rise to complete the reset, and restore the initial state of the next winding battery core;

[0022] Unlike the first feeding, there is no need to manually apply the rubber strips to the subsequent wound battery cells: after the two sets of pressure plates squeeze the wound battery cells, start the third cylinder, which drives the transverse cutting knife on the cylinder extension rod to squeeze the rubber strips and the top edge slider close to the conveyor belt toward the folding plate. At the same time, the contact roller applies the rubber strips to the upper surface of the first set of wound battery cells and the lower surface of the subsequent wound battery cells. After moving to a certain limit, the return spring squeezes the top edge slider to prevent the top edge slider from moving further, and the transverse cutting knife squeezes the rubber strips to the side of the top edge slider to complete the cutting. After completion, the lower wound battery cells fall to the surface of the conveyor belt for transportation, and the upper wound battery cells wait again for the next set of wound battery cells to be glued.

[0023] The device has a simple structure. It utilizes the sliding action of the slider on the top edge of the wound battery cell to prevent curling that affects the resistivity when the wound battery cell is extruded. It also simplifies the process of sticking adhesive strips to prevent the wound battery cell from spreading during subsequent transportation. At the same time, it utilizes a feeding piece to simplify the feeding process, avoid danger, and effectively improve the standardization of subsequent process steps. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

While the circumferential movable rod 31 rotates, it continues to drive the first pressure plate 21 and the second pressure plate 22 to flip outward, so that the first pressure plate 21 and the second pressure plate 22 are separated, and the top edge slider 23 and the folding plate 24 continue to be connected to the first pressure plate 21 by the circular protrusion 232 in the circular through groove 211. The contact rod 441 gradually separates from the movable support rod 42 and slides onto the oblique folding portion 421 during the movement of the circumferential movable rod 31 toward the outer end of the transverse sliding groove 331. The lifting and unloading plate 44 is The gravity of the second cylinder 45 drives the lifting and unloading plate 44 to descend along the guiding direction of the dovetail protrusion 442, driving the winding battery core clamped by the pushing plate 46 on the second cylinder 45 to descend, and the winding battery core pulls the rubber strip to extend. At the same time, the rubber strip on the side is driven by the torsion of the torsion spring 482 on the roller support rod 481 to squeeze and fit the winding battery core, completing the side gluing of the first group of winding battery cores. After that, the first cylinder 35 is continued to be started to extend, driving the circumferential movable rods 31 at both ends to move together, and at the same time restoring the splicing state of the pressing plate parts, that is, the rectangular protrusion 231 of the top edge slider 23 on the first pressing plate 21 continues to be inserted into the rectangular opening groove 221, and at the same time, the movable support rod 42 is squeezed and aggregated toward the center. The movable slide groove 411 on the linkage plate 41 can prevent action interference, and the contact rod 441 on the oblique folding part 421 drives the lifting and unloading plate 44 to rise and complete the reset, restoring the initial state of the next winding battery core;

[0051] Unlike the first feeding, there is no need to manually stick the rubber strips on the subsequent wound battery cells: after the two groups of pressure plates squeeze the wound battery cells, start the third cylinder 49, and the third cylinder 49 drives the transverse cutting knife 493 on the cylinder extension rod 492 to squeeze the rubber strips and the top edge slider 23 close to the conveyor belt 5 toward the folding plate 24, and at the same time, the contact roller 491 sticks the rubber strips to the upper surface of the first group of wound battery cells and the lower surface of the subsequent wound battery cells. After moving to a certain limit, the return spring 25 squeezes the top edge slider 23 to prevent the top edge slider 23 from continuing to move, and the transverse cutting knife 493 squeezes the rubber strips to the side of the top edge slider 23 to complete the cutting. After completion, the lower wound battery cells fall to the surface of the conveyor belt 5 for transportation, and the upper wound battery cells wait again for the next group of wound battery cells to be glued.
