Description

Technical Field

[0002] With the development and maturity of new energy technologies, the application of lithium batteries is becoming more and more extensive. The production process of lithium batteries involves multiple production processes. For example, the scribing process can form grooves on the surface of the pole piece to store electrolyte, so as to increase the electrolyte infiltration effect and speed, reduce the pore tortuosity of the electrode, and effectively improve the lithium ion diffusion coefficient, thereby improving the battery cycle retention rate, reducing the battery internal resistance, and reducing the negative electrode lithium precipitation. The gap channel formed by scribing helps to transport lithium ions to the bulk electrode, thereby reducing the concentration gradient during fast charging. It can also be used as a linear diffusion path to quickly transport ions to the bulk electrode and promote in-plane and through-plane transmission; due to improved transportation, the lithium ion concentration of the entire electrode volume is more uniform, and the battery polarization is reduced, thereby achieving fast charging.

[0021] Specifically, the pole piece unwinding device 10, the first laser etching device 20, the second laser etching device 30 and the pole piece winding device 40 are all arranged on the rear box frame group 2, and the pole piece material strip circulates among the pole piece unwinding device 10, the first laser etching device 20, the second laser etching device 30 and the pole piece winding device 40 in sequence. The pole piece material strip is loaded through the pole piece unwinding device 10, and the front and back sides of the pole piece material strip are laser etched and marked through the first laser etching device 20 and the second laser etching device 30, and the pole piece material strip is wound through the pole piece winding device 40; the whole process is only carried out at the rear box frame group 2, and there is no need to circulate the pole piece material strip at other equipment, thereby improving production efficiency and reducing human contact and pollution caused by the circulation of the pole piece material strip.

[0022] Furthermore, the front box frame group 1 adopts a multi-sliding door with a slide rail structure, which is convenient for the opening of the front box frame group 1 and reduces the space occupied by the front box frame group 1. The top of the front box frame group 1 is provided with an FFU laminar air supply unit for filtering the air inside the front box frame group 1 to ensure the cleanliness of the inside of the front box frame group 1 during the production process; the rear box frame group 2 mainly supports the pole piece unwinding device 10, the first laser etching device 20, the second laser etching device 30 and the pole piece winding device 40 , providing a stable working condition for each device arranged on the upper rear box frame group 2 to ensure the marking accuracy; the dust collecting device 3 is connected to the rear box frame group 2, and an airflow with ultrasonic characteristics is transmitted to the interior of the rear box frame group 2 through the ultrasonic dust removal fan in the dust collecting device 3 to agitate the dust inside the rear box frame group 2 to loosen it, and at the same time, the loose dust is collected by the negative pressure dust collector in the dust collecting device 3, and the air in the rear box frame group 2 is filtered to ensure the cleanliness of the interior of the rear box frame group 2.

[0023] Please refer to Figure 7, the arrow in the figure represents the flow direction of the electrode material strip, and the flow direction points from the feed side to the discharge side. The electrode unwinding device 10 is used to provide a electrode material strip with a clean surface, so that the first laser etching device 20 and the second laser etching device 30 can mark the surfaces on both sides of the electrode material strip; the electrode coil is arranged on the unwinding mechanism 11, and the electrode coil is fixed by the inflatable shaft on the unwinding mechanism 11, and a sticker is arranged at the tail of the electrode coil. A sticker detection mechanism 100 is arranged on the discharge side of the unwinding mechanism 11, and the electrode material strip passes through the sticker detection mechanism 100. The sticker detection mechanism 100 is provided with a photoelectric sensor and a color mark sensor. When the sticker detection mechanism 100 detects the sticker arranged at the tail of the electrode coil, the sticker detection mechanism 100 sends a warning signal to remind the on-site staff to replace the electrode coil. Then the pole piece material belt flows from the adhesive detection mechanism 100 to the magnetic chip removal mechanism 12. The magnetic chip removal mechanism 12 is set on both sides of the pole piece material belt. The magnetic chip removal mechanism 12 absorbs the iron filings or iron powder on the surface of the pole piece material belt to improve the cleanliness of the pole piece surface. Then the pole piece material belt flows to the pole piece splicing mechanism 300. The pole piece splicing mechanism 300 includes a splicing platform, a splicing pressure plate and a cylinder. The pole piece material belt passes between the splicing platform and the splicing pressure plate. When it is necessary to continue the broken pole piece material belt, the on-site staff drives the splicing pressure plate down through the cylinder to fix the broken pole piece material belt, and then re-pastes the broken pole piece material belt. When the broken pole piece material belt is continued, the on-site staff drives the splicing pressure plate up through the cylinder so that the pole piece material belt can continue to flow. A brush dust removal mechanism 13 is also provided on the discharge side of the unwinding mechanism 11. The brush dust removal mechanism 13 includes two dust removal brushes rotating at the same speed and in opposite directions. The pole piece strip passes between the two dust removal brushes to remove dust on the surfaces of both sides of the pole piece strip, further improving the cleanliness of the pole piece surface.

[0024] Please refer to Figure 6 , the arrow in the figure represents the flow direction of the pole piece material strip, and the flow direction points from the feed side to the discharge side. A tension adjustment mechanism 22, a travel correction mechanism 200 and a pole piece drive mechanism 400 are arranged between the pole piece unwinding device 10 and the first laser etching device 20; the tension adjustment mechanism 22 arranged here is used to tension the pole piece material strip between the pole piece unwinding device 10 and the first laser etching device 20; the travel correction mechanism 200 is used to prevent the pole piece material strip between the pole piece unwinding device 10 and the first laser etching device 20 from running off, resulting in the first laser etching device 20 performing laser etching and marking operations on the pole piece material strip. The etching marks formed on the surface of the pole piece material strip do not meet the etching requirements; the pole piece drive mechanism 400 is used to drive the pole piece material strip to move and stabilize the tension of the pole piece material strip during circulation.

[0025] Please refer to Figure 6 and Figure 8, the arrow in the figure represents the flow direction of the pole piece material strip, and the flow direction points from the feed side to the discharge side. The pole piece material strip passes through the tension adjustment mechanism 22, the traveling correction mechanism 200 and the pole piece driving mechanism 400 from the discharge side of the pole piece unwinding device 10 in turn, and flows to the first laser etching device 20. The pole piece material strip passes through the laser scribing mechanism 21, the tension adjustment mechanism 22 and the CCD detection mechanism 23 in the first laser etching device 20 in turn. The laser scribing mechanism 21 laser etches and marks one side of the pole piece material strip, and the tension adjustment mechanism 22 tensions the pole piece material strip after laser etching and marking, so that the CCD detection mechanism 23 can detect the etching marks at the workstation where the tension adjustment mechanism 22 is located to determine whether the etching depth meets the etching requirements.

[0026] Furthermore, a labeling mechanism 700 is provided at the discharge side of the first laser etching device 20, and the labeling mechanism 700 provided here is electrically connected to the CCD detection mechanism 23 in the first laser etching device 20; when the CCD detection mechanism 23 detects that there is an unqualified area on the surface of the pole piece material strip after laser etching, the CCD detection mechanism 23 sends a labeling signal to the labeling mechanism 700, and the labeling mechanism 700 performs a labeling operation on the surface of the pole piece material strip; when the CCD detection mechanism 23 does not detect that there is an unqualified area on the surface of the pole piece material strip after laser etching, the CCD detection mechanism 23 sends a stop labeling signal to the labeling mechanism 700, and the labeling mechanism 700 stops performing a labeling operation on the surface of the pole piece material strip.

[0027] Furthermore, a glue detection mechanism 100 is provided at the feeding side of the first laser etching device 20, and the glue detection mechanism 100 is provided here for detecting whether there is a continuous glue on the electrode strip produced when the electrode strip is spliced.

[0028] Please refer to Figure 6 The arrow in the figure represents the flow direction of the electrode material strip, and the flow direction is from the feed side to the discharge side. A pole piece connecting mechanism 300, a traveling correction mechanism 200 and a pole piece driving mechanism 400 are arranged between the first laser etching device 20 and the second laser etching device 30; since part of the material on the pole piece tape is removed after the surface of the pole piece tape is laser etched and marked, the strength of the pole piece tape will deteriorate. When the pole piece tape after laser etching and marking is tensioned, there is a risk of the pole piece tape breaking. At this time, the pole piece tape that has broken can be connected through the pole piece connecting mechanism 300 so that the pole piece tape can continue to flow; the traveling correction mechanism 200 is used to prevent the pole piece tape between the first laser etching device 20 and the second laser etching device 30 from running off, resulting in the etching marks formed on the surface of the pole piece tape not meeting the etching requirements when the second laser etching device 30 performs laser etching and marking operations on the pole piece tape; the pole piece driving mechanism 400 is used to drive the pole piece tape to move and stabilize the tension of the pole piece tape during circulation.

[0029] Please refer to Figure 6 and Fig. 9 , the arrow in the figure represents the flow direction of the pole piece material strip, and the flow direction points from the feed side to the discharge side. The pole piece material strip passes through the pole piece connection mechanism 300, the travel correction mechanism 200 and the pole piece driving mechanism 400 set between the first laser etching device 20 and the second laser etching device 30 in turn, and flows to the feed side of the second laser etching device 30, and then passes through the laser scribing mechanism 21, the tension adjustment mechanism 22 and the CCD detection mechanism 23 in the second laser etching device 30 in turn; the laser scribing mechanism 21 in the second laser etching device 30 laser etches and marks the other side of the pole piece material strip, and the tension adjustment mechanism 22 tensions the pole piece material strip after laser etching and marking, so that the CCD detection mechanism 23 can detect the etching marks at the position where the tension adjustment mechanism 22 is located, and judge whether the etching depth meets the etching requirements.

[0030] Furthermore, a glue detection mechanism 100 is provided on the feeding side of the second laser etching device 30, and the glue detection mechanism 100 is used to detect whether there is a continuous glue on the electrode sheet tape generated when the electrode sheet tape is spliced.

[0031] Please refer to Figure 6 , the arrow in the figure represents the flow direction of the pole piece material strip, and the flow direction points from the feed side to the discharge side. An electrostatic dust removal mechanism 500 and an ultrasonic dust removal mechanism 600 are arranged between the second laser etching device 30 and the pole piece winding device 40; the pole piece material strip first flows to the electrostatic dust removal mechanism 500, and the electrostatic dust removal mechanism 500 blows out ion wind to remove the static electricity on both sides of the surface of the pole piece material strip, and then the pole piece material strip after the static electricity removal is completed flows to the ultrasonic dust removal mechanism 600, and the ultrasonic dust removal mechanism 600 removes the dust generated on the surface of the pole piece material strip due to laser etching and scribing, so as to further ensure the cleanliness of the surface of the pole piece material strip.

[0032] Please refer to Figure 6 and Fig.10 , the arrow in the figure represents the flow direction of the pole piece material strip, and the flow direction points from the feed side to the discharge side. The pole piece material strip processed by the electrostatic dust removal mechanism 500 and the ultrasonic dust removal mechanism 600 flows to the pole piece winding device 40, and the pole piece winding device 40 winds up the pole piece material strip that has been laser etched and marked on both sides for easy storage. The pole piece winding device 40 includes a smoothing mechanism 41, a winding diameter measuring mechanism 42 and a winding mechanism 43. The smoothing roller in the smoothing mechanism 41 acts on the surface of the pole piece material strip to smooth the pole piece material strip to prevent wrinkles and stacking of the rolled material during winding; the winding diameter measuring mechanism 42 is arranged on the outside of the winding mechanism 43, and an ultrasonic sensor is arranged in the winding diameter measuring mechanism 42. The distance between the rolled material on the winding mechanism 43 and the winding diameter measuring mechanism 42 is measured by the ultrasonic sensor to obtain the diameter of the rolled material.

[0033] Please refer to Figure 1 and Figure 4 , an integrated device for producing pole pieces, also includes a laser water cooler 4, which is used to provide circulating cooling water for the first laser etching device 20 and the second laser etching device 30 to stabilize the operating temperature of the laser scribing mechanism 21 in the first laser etching device 20 and the second laser etching device 30, so that the laser generator can work normally for a long time.
