This improves the structural strength of the tabs. However, during the embossing process, because the tabs are deformed by the embossing wheel, dirt and debris inevitably remain on the roller. This dirt and debris can easily adhere to the electrode surface, causing secondary contamination and affecting the production quality of the electrode sheets. Utility Model Content

[0041] like Figure 3As shown, this application proposes a laser cutting device, which includes a frame, an unwinding mechanism 20, a tape-connecting platform 30, a tension swing arm mechanism 40, a laser mechanism 50, a main drive mechanism 60, a slitting mechanism 70, a winding mechanism 80, and an embossing device 10 described below. The unwinding mechanism 20, the tape-connecting platform 30, the tension swing arm mechanism 40, the embossing device 10, the laser mechanism 50, the main drive mechanism 60, the slitting mechanism 70, and the winding mechanism 80 are connected to the frame and arranged along the direction from input to output of the laser cutting device. In practical applications, the unwinding mechanism 20 is equipped with a roll of material containing the electrode sheet 100. The unwinding mechanism 20 is used to unwind the electrode sheet 100, and the winding mechanism 80 is used to wind the electrode sheet 100. The direction from input to output of the laser cutting equipment refers to the conveying direction of the electrode sheet 100 roll from the unwinding mechanism 20 to the winding mechanism 80. The receiving platform 30 is used to receive the electrode sheet 100 output from the unwinding mechanism 20, the tension swing arm mechanism 40 is used to tension the electrode sheet 100, the embossing device 10 is used to emboss the electrode tabs of the electrode sheet 100, the laser mechanism 50 is used to cut the electrode sheet 100 into electrode tabs of a preset length, the main drive mechanism 60 is used to drive the electrode sheet 100 forward along its conveying direction, and the slitting mechanism 70 is used to slit the electrode sheet 100 into individual electrode sheets 100 of a preset length.

[0042] Since the laser cutting equipment described above uses the embossing device 10, the laser cutting equipment also has the advantages of the embossing device 10.

[0043] like Figures 1 to 2 As shown, a preferred embodiment of the present invention provides an embossing device 10 for embossing the tabs of an electrode sheet 100. The device includes an embossing mechanism 1 and a cleaning mechanism 2. The embossing mechanism 1 includes an embossing wheel 11, a roller body 12, and a first drive assembly 13. The embossing wheel 11 has a first axis 110 and is rotatable around the first axis 110. The roller body 12 has a second axis 120 and is rotatable around the second axis 120. The embossing wheel 11 and the roller body 12 are spaced apart. 11 is connected to the first drive assembly 13, which drives the embossing wheel 11 to move so as to press the electrode 100 onto the roller body 12; the cleaning mechanism 2 is located on the side of the roller body 12 away from the embossing wheel 11. The cleaning mechanism 2 includes an adhesive component 21, a second drive assembly 22 and a fixing assembly 23. The adhesive component 21 is connected to the fixing assembly 23, and the fixing assembly 23 is spaced apart from the roller body 12. The second drive assembly 22 drives the adhesive component 21 to contact the roller body 12 so as to clean the roller body 12.

[0044] In practical applications, the adhesive component 21 facing the roller body 12 is adhesive. The electrode sheet 100 to be embossed is positioned between the embossing wheel 11 and the roller body 12. When the embossing device 10 embosses the tabs of the electrode sheet 100, the first drive assembly 13 drives the embossing wheel 11 to move. The embossing wheel 11 presses the tabs onto the roller body 12. During the conveying process of the electrode sheet 100, the embossing wheel 11 and the roller body 12 rotate, and the tabs are pressed into protrusions and indentations by the embossing wheel 11. During this process, the adhesive component 21 and the roller body 12 are spaced apart (not in contact); and when When the roller 12 needs cleaning, the second drive assembly 22 drives the adhesive part 21 to contact the roller 12, and the adhesive part 21 removes dirt and debris from the roller 12. This avoids secondary contamination of the electrode 100 surface. In other words, applying the embossing device 10 to the production of the electrode 100 can ensure the production quality of the electrode 100. In addition, there is no need for manual intervention to stop the machine to wipe the roller, which is beneficial to improving production efficiency. When the roller 12 no longer needs to be cleaned, the second drive assembly 22 resets so that the adhesive part 21 is reset to a state that is spaced apart from the roller 12.

[0045] In this application, the fixing component 23 includes an unwinding component 231 and a winding component 232. The adhesive component 21 is strip-shaped, with one end connected to the unwinding component 231 and the other end connected to the winding component 232 along its length. In practical applications, the adhesive component 21 is rolled into an adhesive roll, which is mounted on the unwinding component 231. The unwound portion of the adhesive roll is connected to the winding component 232. During the cleaning of the roller body 12, the adhesive roll can unwind the adhesive component 21 under the action of the winding component 232, and the winding component 232 can wind up the adhesive component 21. Thus, the portion of the adhesive component 21 covered with dirt and debris can be wound away, and the portion of the adhesive component 21 without dirt and debris can remove dirt and debris from the roller body 12. Based on this, the cleaning effect of the roller body 12 can be improved, and frequent manual intervention to replace the adhesive component 21 is not required, which is beneficial to improving production efficiency.

[0046] The second drive assembly 22 is located between the unwinding component 231 and the winding component 232, and is located on the side of the adhesive component 21 away from the roller body 12. The second drive assembly 22 includes a pressure roller 221, a first connecting frame 222, a first drive member 223, and a first mounting base 224. The pressure roller 221 is connected to the first connecting frame 222 and has a third axis 2210, which allows the pressure roller 221 to rotate around. The first connecting frame 222 is connected to the first drive member 223. The first drive member 223 is connected to the first mounting base 224, which is fixedly connected to the frame of the laser cutting equipment. The first drive member 223 drives the pressure roller 221 to move toward the roller body 12, so that the adhesive component 21 adheres to the roller body. 12. Contact: Specifically, the side of the adhesive part 21 facing the pressure roller 221 is not sticky. Since the pressure roller 221 can rotate around the third axis 2210, during the winding process of the winding component 232, the adhesive part 21 will drive the pressure roller 221 to rotate around the third axis 2210. Rolling friction is generated between the adhesive part 21 and the pressure roller 221. The friction force is relatively small, which makes the winding process of the adhesive part 21 smoother. The first driving component 223 is a cylinder. Therefore, the extension degree of the cylinder piston rod can be adjusted by adjusting the air pressure, thereby adjusting the downward stroke of the pressure roller 221, and thus adjusting the contact degree between the adhesive part 21 and the pressure roller 221. Based on this, the cleaning effect of dirt on the roller body 12 can be improved according to the actual situation.

[0047] In the extension direction of the third axis 2210, the position of the first driving member 223 is adjustable. Thus, by adjusting the position of the first driving member 223, the pressure roller 221 can be aligned with the adhesive part 21, so as to ensure that the pressure roller 221 can accurately press the adhesive part 21 onto the roller body 12, thereby ensuring the cleaning effect. As one specific implementation of this application, the first mounting frame is an aluminum profile. The first driving member 223 is fixed to the first mounting frame by a connector. By removing the connector, the first driving member 223 can move in the extension direction of the third axis 2210. After the first driving member 223 is adjusted to a suitable position (the pressure roller 221 is aligned with the adhesive part 21), the first driving member 223 is fixed to the first mounting frame by the connector.

[0048] The unwinding component 231 includes an unwinding shaft 2311 and a first roll 2312. The unwinding shaft 2311 has a fourth axis 23110. The unwinding shaft 2311 is connected to the frame of the laser cutting equipment through a bearing seat. The unwinding shaft 2311 can rotate around the fourth axis 23110. The first roll 2312 is connected to the unwinding shaft 2311 and can rotate with the unwinding shaft 2311 around the fourth axis 23110. One end of the adhesive roll 21 along its length is connected to the first roll 2312. The adhesive roll is connected to the first roll 2312. This structure of the unwinding component 231 is simple and easy to assemble. In addition, the unwinding shaft 2311 unwinds the adhesive roll with damping but without power, so that the adhesive roll 21 has a certain tension, thereby ensuring the smooth progress of the cleaning work.

[0049] As a preferred embodiment of this application, the position of the first roll 2312 is adjustable in the extension direction of the fourth axis 23110. Specifically, the first roll 2312 is fixed to the unwinding shaft 2311 by fasteners, such as clamps. Fasteners are provided on both sides of the first roll 2312 in the extension direction of the fourth axis 23110. The first roll 2312 is fixedly connected to the unwinding shaft 2311 by the fasteners. Based on this, the position of the first roll 2312 can be adjusted by loosening the fasteners. When the position of the first roll 2312 is adjusted to the correct position, the fasteners can be tightened to fix the first roll 2312. In this process, the position of the fasteners changes with the position of the first roll 2312. The structure is simple and the operation is convenient. Since the position of the first roll 2312 is adjustable, the adhesive part can be adjusted to a straight state by adjusting the position of the first roll 2312, thereby ensuring the cleaning effect.

[0050] The take-up component 232 includes a take-up shaft 2321, a second drum 2322, and a second drive member 2323. The take-up shaft 2321 is connected to the second drive member 2323. The take-up shaft 2321 has a fifth axis 23210 and is connected to the frame of the laser cutting equipment via bearings. The second drive member 2323 drives the take-up shaft 2321 to rotate around the fifth axis 23210. The second drum 2322 is connected to the take-up shaft 2321 and can follow the take-up shaft. 2321 rotates around the fifth axis 23210; the other end of the adhesive component 21 along its length is connected to the second drum 2322; specifically, the second drive component 2323 is a motor, the second drive component 2323 is fixed on the frame of the laser cutting equipment, and the second drive component 2323 is connected to the take-up shaft 2321 through a coupling. In practical applications, the motor drives the take-up shaft 2321 to rotate around the fifth axis 23210, so that the take-up shaft 2321 takes up the adhesive component 21 through the second drum 2322.

[0051] As a preferred embodiment of this application, the position of the second drum 2322 is adjustable in the extension direction of the fifth axis 23210. Similarly, the second drum 2322 is also fixed to the take-up shaft 2321 by fasteners such as clamps. The adjustment process of the position of the second drum 2322 is the same as the adjustment process of the position of the first drum 2312. First, loosen the fasteners, then adjust the position of the second drum 2322, and then tighten the fasteners again. This application will not elaborate further on this.

[0052] The advantage of adjustable positions of the first roll 2312 and the second roll 2322 is that the position of the adhesive part 21 can be flexibly adjusted according to the actual dirty position of the roller 12 to ensure the cleaning effect; after adjusting the position of the adhesive part 21, the position of the first drive part 223 can be adjusted simultaneously to make the pressure roller 221 aligned with the adhesive part 21.

[0053] The first drive assembly 13 includes a second connecting frame 131, a third drive member 132, and a second mounting base 133. An embossing wheel 11 is connected to the second connecting frame 131, the second connecting frame 131 is connected to the third drive member 132, and the third drive member 132 is connected to the second mounting base 133. The second mounting base 133 is fixedly connected to the frame of the aforementioned laser cutting equipment. The third drive member 132 drives the embossing wheel 11 to move via the second connecting frame 131, thereby pressing the electrode sheet 100 onto the roller body 12. The position of the third drive member 132 is adjustable in the extending direction of the first axis 110. Specifically, for electrode sheets 100 of different widths, their tabs... The position of the embossing roller 11 will vary, so the position of the third drive component 132 is adjustable. Its advantage is that the position of the embossing roller 11 can be adjusted by adjusting the position of the third drive component 132, so that the embossing device 10 can be compatible with electrode sheets 100 of different widths, and has high adaptability. In addition, after adjusting the position of the embossing roller 11, the position of the dirt on the roller body 12 will also change. Therefore, the position of the adhesive component 21 can be adjusted by adjusting the position of the first roll 2312 and the second roll 2322, and the position of the pressure roller 221 can be adjusted by adjusting the position of the first drive component 223, so as to ensure the cleaning effect of the dirt on the roller body 12.

[0054] The aforementioned third driving component 132 can be a cylinder, an electric cylinder, etc., and this application does not limit it.

[0055] As one specific implementation of this application, the second mounting base 133 is also made of aluminum profile, and the third driving component 132 is also fixed to the second mounting base 133 by a connector. The method of adjusting the position of the third driving component 132 is the same as that of adjusting the position of the first driving component 223. It is also achieved by disassembling the connector, adjusting the position of the third driving component 132, and then reinstalling the connector. This application will not elaborate further on this.

[0056] In this application, the first axis 110, the second axis 120, the third axis 2210, the fourth axis 23110, and the fifth axis 23210 are parallel to each other. In the extension direction of the first axis 110, the length of the roller body 12 is greater than the length of the embossing wheel 11, and the length of the roller body 12 is greater than the length of the electrode sheet 100 in the extension direction of the first axis 110.

[0057] In some embodiments, such as Figure 1 As shown, in the extension direction of the first axis 110, both ends of the electrode 100 are tabs to be embossed, that is, the electrode 100 has two tabs. At this time, the number of the first roll 2312, the second roll 2322, the adhesive part 21, and the embossing wheel 11 are all two. One first roll 2312, one second roll 2322, and one adhesive part 21 cooperate to form a cleaning component. One embossing wheel 11 is used to emboss one tab. At this time, there are two positions on the roller body 12 that need to be cleaned. Thus, one cleaning component cleans one position on the roller body 12 that needs to be cleaned.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
