Description

Technical Field

[0001] The utility model belongs to the technical field of pole piece production, and particularly relates to a tape sticking device. Background Art

[0002] In the production process of battery pole pieces, roller separation is an important technological step. The roller separation process is usually divided into two links: coating and rolling. In the coating link, electrode materials (such as positive electrode materials and negative electrode materials) are uniformly coated on aluminum foil or copper foil in the form of slurry to form the basic layer of the electrode. These slurries are usually composed of active materials, conductive agents, binders and solvents. In the rolling link, after the coated electrode materials are dried and cured to a certain extent, they are then rolled by a rolling machine. The purpose of rolling is to compact the electrode materials, improve their density and consistency, thereby enhancing the performance and lifespan of the battery.

[0003] When the pole piece passes through the rollers of the rolling machine under pressure and moves forward, the pole piece tab is prone to breakage and damage. Therefore, it is usually necessary to stick a compressible tape on the pole piece tab for protection. In the prior art, the method of sticking a compressible tape on the pole piece tab mostly involves sticking the head of the tape strip on the pole piece tab, and then manually holding the tape and unrolling the tape along with the movement of the pole piece, so that the tape is attached to each pole piece tab.

[0004] The disadvantage of this tape sticking method is that the running speed of the pole piece should not be too fast, and the length of each tape sticking should not be too long, otherwise it is easy to cause the tape to be stuck crookedly; in addition, if the hand shakes when manually holding the tape, it may also cause the tape to be stuck crookedly, thus affecting the production of the pole piece.

[0056] Embodiment 1:

[0057] This embodiment provides a tape sticking device, including:

[0058] Base frame 1;

[0059] Locking mechanism 2, which is movably installed on the base frame 1 along the first direction X;

[0060] Support mechanism 3, which is movably installed on the locking mechanism 2 along the second direction Y;

[0061] Tensioning mechanism 4, which is rotatably installed on the support mechanism 3 and is used to tension and fix the core of the tape;

[0062] The traction mechanism 5 is installed on the support mechanism 3 and is used to traction the film of the tape for tape running movement.

[0063] In this technical solution, the tape sticking device is installed downstream of the pole piece unwinding buffer device. The tape for sticking the pole ear is sleeved on the tensioning mechanism 4. Then, the tensioning mechanism 4 expands and abuts against the core of the tape so that the tape is fixed on the tensioning mechanism 4. Then, by moving the locking mechanism 2 along the first direction X and moving the support mechanism 3 along the second direction Y, the tensioning mechanism 4 on the support mechanism 3 is adjusted to a proper position so that the tape is flush with the pole ear of the unwound pole piece.

[0064] After the position of the tape is adjusted to the correct position, the sticking operation is carried out. The head of the tape passes through the traction mechanism 5 and is stuck on the pole ear of the unwound pole piece. As the pole piece runs, it will pull the tape strip to move along the running route. At the same time, the core of the tape will drive the tensioning mechanism 4 to rotate under the action of the traction force, so as to realize the automatic unwinding of the tape, and there is no need for manual holding of the tape for unwinding and sticking.

[0065] In summary, by installing this tape sticking device behind the pole piece unwinding device, adjusting the position of the tensioning mechanism 4 according to the position of the pole ear of the pole piece, and then installing the tape on the tensioning mechanism 4, the automatic unwinding and sticking of the tape are realized, effectively reducing the labor input, improving the production efficiency, and also avoiding the situation of the tape being stuck crooked, with high practicability.

[0066] Embodiment 2:

[0070] The adjustment component 42, the adjustment component 42 is installed on the connection component 41 and can be axially telescoped and adjusted along the first direction X;

[0071] A plurality of tensioning components 43, the plurality of tensioning components 43 are installed on the adjustment component 42, and the tensioning components 43 will be radially tensioned as the adjustment component 42 axially telescopes.

[0072] Further, the adjustment component 42 includes:

[0073] The fixing part 421, and the fixing part 421 is installed on the connection component 41;

[0074] The sliding part 422, and the sliding part 422 is movably installed on the connection component 41 along the first direction X;

[0075] The elastic member 423 is disposed between the fixed member 421 and the sliding member 422;

[0076] The limiting member 424 is installed on the connecting assembly 41 and is used to limit the movement of the sliding member 422.

[0077] In this technical solution, the connecting assembly 41 is integrally rotatably installed on the support mechanism 3. The connecting assembly 41 includes a slide rod 411. The fixed member 421 is sleeved and fixed on the slide rod 411. The sliding member 422 is also sleeved on the slide rod 411 and can move along the first direction X (i.e., the axial direction of the slide rod 411). An elastic member 423 is disposed between the sliding member 422 and the fixed member 421. The elastic member 423 can be a spring. As the sliding member 422 slides closer to or farther away from the fixed member 421, the elastic member 423 will be correspondingly compressed or extended. The elastic member 423 is used to enable the sliding member 422 to perform axial telescopic movement on the slide rod 411.

[0078] The limiting member 424 is axially movably installed on the end of the slide rod 411 and abuts against the sliding member 422 to limit the axial movement of the sliding member 422. The connection between the limiting member 424 and the slide rod 411 can be a threaded connection. By designing a threaded section with a certain length at the end of the slide rod 411, the limiting member 424 can be a nut, and the limiting member 424 is threadedly connected to the threaded section.

[0079] Through the above structural design, by rotating and adjusting the threaded connection amount between the limiting member 424 and the slide rod 411, the position of the limiting member 424 on the slide rod 411 is adjusted, and at the same time, the sliding member 422 is driven to move to make the elastic member 423 expand and contract, so as to realize the function of axially telescopic adjustment of the adjusting assembly 42.

[0080] Further, the tensioning assembly 43 includes:

[0081] The tensioning plate 431;

[0082] The first connecting rod 432, with both ends of the first connecting rod 432 hinged to the tensioning plate 431 and the sliding member 422 respectively;

[0084] The third connecting rod 434, with both ends of the third connecting rod 434 hinged to the tensioning plate 431 and the sliding member 422 respectively.

[0085] In this technical solution, as shown in the figure, the tensioning plate 431 has an arc-shaped structure. The outer wall of the tensioning plate 431 is used to abut against the core of the tape. The inner wall of the tensioning plate 431 is connected to the sliding member 422 through the first connecting rod 432 and the third connecting rod 434. The first connecting rod 432 is connected to the fixing member 421 through the third connecting rod 434. Through this structural design, when the sliding member 422 moves axially along the slide bar 411 close to or away from the fixing member 421, the tensioning plate 431 will move radially away from or close to the slide bar 411 along the slide bar 411, thereby realizing the radial tensioning movement of the tensioning assembly 43.

The traction roller 52 is rotatably mounted on the swing rod 51 for traction of the tape strip.

[0101] In this technical solution, the support portion 21 is used to support the support mechanism 3 and the tensioning mechanism 4 and the traction mechanism 5 mounted on the support mechanism 3.
