Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, in particular to a non-stop automatic belt splicing mechanism. Background Art

[0002] At present, the automatic tape splicing mechanism of the winding machine that does not stop unwinding generally includes a frame and a traction and cutting assembly arranged on the frame. The traction and cutting assembly is used to pull the unwound substrate of the main material roll to a position close to the spare material roll, press the substrate to the glue-applying position of the spare material roll, and cut the substrate. In actual application, the first unwinding shaft for installing the main material roll and the second unwinding shaft for installing the spare material roll are respectively arranged on the front side of the frame and are located between the traction and cutting assemblies. The traction and cutting assembly is close to the main material roll. When the main material roll is driven to rotate by the first unwinding shaft to unwind the main material roll normally, the substrate of the main material roll (the substrate is, for example, a diaphragm, an electrode, etc.) passes over the traction and cutting assembly. When the substrate of the main material roll is about to be released and is in an empty roll state, the spare material roll is driven to rotate by the second unwinding shaft and the diameter of the spare material roll is detected by the roll diameter sensor to calculate the spare material roll. Using the linear speed of the material roll surface, the substrate is pulled to a position close to the spare material roll through the traction and cutting assembly, and then the second unwinding shaft drives the spare material roll to accelerate the rotation according to the calculated linear speed of the spare material roll surface, so that the linear speed of the spare material roll surface matches the tape feeding speed of the substrate, and then according to the gluing position of the spare material roll detected by the camera, the traction and cutting assembly is controlled to press the substrate to the gluing position of the spare material roll, so that the substrate and the tape of the spare material roll can be bonded together, and then the substrate is cut off by the traction and cutting assembly, thus completing the roll change and tape splicing.

[0003] In the above structure, due to the accuracy problem of the roll diameter sensor, the calculated linear speed of the surface of the spare material roll will have deviations, and thus it is impossible to ensure that the linear speed of the surface of the spare material roll matches the tape feeding speed of the substrate, resulting in the traction and cutting component being unable to accurately press the substrate to the gluing position of the spare material roll, so that the substrate and the tape of the spare material roll cannot be accurately bonded together, resulting in unsuccessful splicing, which reduces the efficiency of reel changing and splicing.

When the main material roll 101 is driven to rotate by the first unwinding shaft to unwind the main material roll 101 normally, the substrate 100 of the main material roll passes through the traction roller 342 of the traction roller 34, the roller shaft of the second passing roller 42, the roller shaft of the first passing roller 41, the buffer roller 222 of the fixed buffer roller 23 on the right, the buffer roller 222 of the sliding buffer roller 22 on the right, the buffer roller 222 of the fixed buffer roller 23 in the middle, the buffer roller 222 of the sliding buffer roller 22 on the left, and the buffer roller 222 of the fixed buffer roller 23 on the left in sequence, as shown in FIG.

When the substrate 100 of the main material roll 101 is about to be released and is in an empty roll state, the first unwinding motor stops driving the first unwinding shaft to rotate, so that the first unwinding shaft can stop driving the main material roll 101 to rotate, and the second unwinding motor drives the second unwinding shaft to rotate, so that the second unwinding shaft can drive the spare material roll 102 to rotate, and the buffer motor 212 drives the sliding buffer roller 22 to move downward to a predetermined position to release the buffered substrate 100, and at the same time drives the swing arm 33 and the traction roller 34 to move rightward by the traction moving drive member and controls the moving speed of the swing roller 33 and the traction roller 34 to match the rotation speed of the spare material roll 102, so that the buffered substrate 100 can be moved rightward to a position close to the spare material roll 102 by the traction roller 34, and the moving speed of the buffered substrate 100 matches the rotation speed of the spare material roll 102, and in the process of the buffered substrate 100 moving rightward, the buffered substrate 100 can be supported by the roller shaft of the third roller 43, such as Figure 3 and Figure 4 As shown, the traction motor 212 is then controlled to start according to the gluing position of the spare material roll 102 detected by the camera, so as to drive the swing arm 33 and the traction roller 34 to rotate rightward through the traction motor 212, so that the cached substrate 100 can be pressed to the gluing position of the spare material roll 102 through the traction roller 34, so that the cached substrate 100 can be bonded to the tape on the spare material roll 102, as shown in FIG. Figure 3 and Figure 4As shown. While the buffered substrate 100 is pressed to the gluing position of the spare material roll 102 by the traction roller 34, the two cutter cylinders 35 drive the cutter 36 to move in the direction close to the through hole 341, so that the cutting part of the cutter 36 extends from the through hole 341 to the outside of the traction roller 34, so that the buffered substrate 100 can be cut by the cutting part 361 of the cutter 36, and the roll change and splicing are completed. After completion, the two cutter cylinders 35 drive the cutter 36 to move in the direction away from the through hole 341, so that the cutting part 361 of the cutter 36 retracts from the through hole 341 to the traction roller shaft 343 of the traction roller 34, and at the same time, the traction motor 312 drives the swing arm 33 and the traction roller 34 to rotate to the left to the initial position, and then the traction moving drive member drives the swing arm 33 and the traction roller 34 to move to the left to the initial position. After the reel is changed and the spliced ​​tape is taken out, the substrate 100 passes through the roller shaft of the third passing roller 43, the roller shaft of the second passing roller 42, the roller shaft of the first passing roller 41, the cache roller 222 of the fixed buffer roller 23 on the right, the cache roller 222 of the sliding buffer roller 22 on the right, the cache roller 222 of the fixed buffer roller 23 in the middle, the cache roller 222 of the sliding buffer roller 22 on the left, and the cache roller 222 of the fixed buffer roller 23 on the left. After that, the substrate 100 of the spare material roll 102 can be unwound normally under the drive of the second unwinding shaft.

[0046] The utility model provides a buffer component, when the substrate 100 of the main material roll 101 is unwound normally, the substrate 100 can be buffered by the sliding buffer roller 22 and the fixed buffer roller 23. When the substrate 100 of the main material roll 101 is about to be released and is in an empty roll state, the main material roll 101 stops rotating, and the sliding buffer roller 22 is driven downward by the buffer moving drive member 21 to release the buffered substrate 100. At the same time, the buffered substrate 100 is pulled to a position close to the spare material roll 102 by the pulling and cutting component, and the buffered substrate 100 is controlled. The moving speed matches the rotation speed of the spare material roll 102, so that after the cached substrate 100 is pulled to a position close to the spare material roll 102 by the traction and cutting component, the cached substrate 100 can be accurately pressed to the gluing position of the spare material roll 102 through the traction and cutting component in conjunction with the tape position of the spare material roll 102 detected by the camera, so that the cached substrate 100 and the tape on the spare material roll 102 are accurately bonded together, and there will be no unsuccessful splicing, which ensures the success rate of splicing and improves the efficiency of reel replacement and splicing.

[0047] The non-stop automatic tape splicing mechanism of the utility model can also be used as an automatic tape changing and splicing for winding up substrates such as diaphragms and pole pieces. The principle of the automatic tape changing and splicing for winding up is the same as that for unwinding, with the only difference being that a first winding shaft and a second winding shaft are respectively arranged at the first mounting hole 12 and the second mounting hole 13. The first winding shaft carries a substrate with a certain winding amount, and the second winding shaft carries an empty material roll. When the first winding shaft is almost full, the utility model can realize automatic tape changing and splicing between the full material roll and the empty material roll.

[0048] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
