Description

Technical Field

[0001] This application relates to the technical field of battery electrode sheet manufacturing, and particularly to a tape sticking device and a laser die-cutting device. Background Art

[0002] The electrode sheet of a battery generally includes a current collector, a tab, and an active material. The active material is generally coated on the surface of the current collector through a coating process. To form a tab on the initial electrode sheet (a large-sized metal foil coated with an active material), a die-cutting process is generally used. However, the die-cutting process is likely to generate burrs at the edge of the current collector, so there is a risk that the burrs pierce the separator and contact the electrode sheet with the opposite polarity, resulting in a short circuit.

[0003] To reduce the short-circuit risk, after the tab is die-cut, a hot-melt tape is attached to the edge area of the current collector near the tab. The hot-melt tape covers the burrs, thereby reducing the risk of the burrs piercing the separator.

[0004] In the related art, the hot-melt tape is pasted on the tab by heating. However, after the hot-melt tape is pasted on the tab, there are still gaps and bubbles between the hot-melt tape and the tab, and the hot-melt tape is not firmly pasted to the tab. Summary of the Utility Model

[0049] Refer to Figures 1 to 3 , it should be noted that Figure 1 and Figure 2 In [reference document] and [another reference document], the straight dotted line represents the hot melt tape 120, and the straight chain double-dotted line represents the electrode tab 110. According to the first aspect embodiment of the present application, the tape sticking device includes a first conveying module 200, a second conveying module 300, a preheating module 400, a heating module 500, and a pressing module 600. The first conveying module 200 is used to convey the electrode tab 110. The electrode tab 110 includes a current collector 111 and an electrode ear 112. Let the edge area of the current collector 111 close to the electrode ear 112 be the sticking area 113.

The second driving component 630 is also used to drive the first pressing roller 610 and the second pressing roller 620 to move away from each other.

[0052] The gluing device according to the embodiment of the present application has at least the following beneficial effects: When the first heating roller 410 and the roller 420 roll the pole piece 110 and the hot melt adhesive tape 120 located in the pasting area 113, the hot melt adhesive tape 120 is preheated and also squeezed, so that the bubbles and gaps between the hot melt adhesive tape 120 and the pole piece 110 can be greatly reduced; After the heating module 500 reheats the hot melt adhesive tape 120, the viscosity of the hot melt adhesive tape 120 is better. After the laminating module 600 rolls the pole piece 110 and the hot melt adhesive tape 120, the hot melt adhesive tape 120 can be better pasted on the pole piece 110, and the bubbles and gaps between the hot melt adhesive tape 120 and the pole piece 110 can be further reduced, and the hot melt adhesive tape 120 is more firmly pasted to the pole ear 112.

[0053] Specifically, the first conveying module 200 includes a first conveying roller 210 and a second conveying roller 220. The pole piece 110 sequentially passes around the first conveying roller 210 and the second conveying roller 220, and the pole piece 110 located between the first conveying roller 210 and the second conveying roller 220 is straightened. The preheating module 400, the heating module 500 and the laminating module 600 are all located between the first conveying roller 210 and the second conveying roller 220. The pole piece 110 can be driven by other driving rollers to sequentially pass around the first conveying roller 210 and the second conveying roller 220.

[0054] Specifically, the second conveying module 300 includes a plurality of third conveying rollers 330, and the plurality of third conveying rollers 330 convey the hot melt adhesive tape 120 to the pasting area 113 of the pole ear 112. After the preliminary heating and lamination of the preheating module 400, the hot melt adhesive tape 120 is preliminarily pasted on the pasting area 113 of the pole ear 112.

[0055] Specifically, the heating module 500 can be one of an electromagnetic heater, a microwave heater, an infrared heater, a hot air heater and a heating roller.

[0056] Specifically, the first driving assembly 430 drives the first heating roller 410 and the roller 420 to approach each other. It can be that the first driving assembly 430 drives the first heating roller 410 to move, so that the first heating roller 410 approaches the roller 420. It can also be that the first driving assembly 430 drives the roller 420 to move, so that the roller 420 approaches the first heating roller 410. It can also be that the first driving assembly 430 drives the first heating roller 410 and the roller 420 to move together, so that the first heating roller 410 and the roller 420 approach each other.

[0057] In some embodiments, referring to Figure 2 , the first driving assembly 430 includes a cylinder 431 and a mounting seat 432. There are two cylinders 431 and two mounting seats 432. The two cylinders 431 drive the two mounting seats 432 to move in opposite directions respectively. The first heating roller 410 is rotatably connected to one mounting seat 432 (which can be realized through a bearing), and the roller 420 is rotatably connected to the other mounting seat 432 (which can be realized through a bearing). Thus, when the two cylinders 431 are ventilated and working, the first heating roller 410 and the roller 420 can be driven to approach or move away from each other.

[0061] By setting the first temperature sensor 440, the temperature of the first heating roller 410 can be monitored in real time, which is beneficial to the closed-loop control of the temperature of the first heating roller 410.

[0062] Specifically, the first heating roller 410 can be an electric heating roller. After the first temperature sensor 440 detects the temperature of the electric heating roller, a feedback signal is generated. After the controller (such as a programmable logic controller) receives the feedback signal, it compares the current temperature and the target temperature of the first heating roller 410 through a PID algorithm and generates an adjustment signal. After the electric heating roller receives the adjustment signal, it adjusts the output power and then adjusts the temperature, thus completing the closed-loop control of the temperature.

[0063] Specifically, the first temperature sensor 440 can be one of an infrared temperature sensor, a thermocouple, and a thermistor. The first heating roller 410 can also be one of a water heating roller, a heat transfer oil heating roller, a steam heating roller, and an electromagnetic induction heating roller.

[0064] Referring Figure 2 , in some embodiments of the present application, the roller 420 includes a second heating roller 421.

[0065] After the roller 420 is set as the second heating roller 421, together with the first heating roller 410, the two sides of the hot melt tape 120 can be heated. The hot melt tape 120 is heated more evenly, the bonding area between the hot melt tape 120 and the tab 112 is larger, and the peeling force after the hot melt tape 120 is bonded to the tab 112 is greater.

[0066] Specifically, the second heating roller 421 can be one of an electric heating roller, a water heating roller, a heat transfer oil heating roller, a steam heating roller, and an electromagnetic induction heating roller.
