Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery production, and specifically relates to an energy-gathering oven. Background Art

[0002] During the battery manufacturing process, after the pole piece is rolled by the cold press, due to the inherent characteristics of the negative electrode material, its rebound rate is relatively high. If the pole piece is directly rolled up, it will affect the performance of the pole piece. In order to solve this problem, the common practice in the industry is to send the rolled pole piece into an oven for heating. The purpose of this step is to reduce the internal stress and rebound of the pole piece through proper heating, thereby improving the stability and reliability of the pole piece.

[0003] At present, there are two main methods for traditional oven heating. The first method is to heat the air and blow the hot air to the surface of the electrode using a fan or a circulating pump to achieve the heating effect. The second method is to use a heating lamp to radiate heat to the electrode. The heat generated by the heating lamp is transferred to the surface of the electrode by radiation, thereby achieving the heating effect.

[0004] However, the above two oven heating schemes can only achieve shallow baking on the surface of the electrode, but cannot perform deep baking or curing treatment inside the electrode, so that the electrode cannot achieve sufficient rebound. Utility Model Content

[0048] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is a contact part embodiment of the utility model, not all embodiments.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0050] Example 1

[0051] Please refer to the attached Figure 1-6This embodiment provides an energy-concentrating oven, including a frame 100, and a first roller 200 and a second roller 300 arranged on the frame 100 along the direction of the pole piece 400. The pole piece 400 enters the oven through the first roller 200, and leaves the oven through the second roller 300 for the next process. It is understandable that a plurality of rollers may be arranged between the first roller 200 and the second roller 300, such as Fig.11 As shown, the roller includes a roller body 940 and a bearing to facilitate the walking of the pole piece 400. The specific number and design position can be designed by those skilled in the art according to actual needs. Since it is a prior art, it is not pointed out in this embodiment.

[0052] A first heating module 1 and a cooling module 2 are sequentially arranged between the first roller 200 and the second roller 300; the first heating module 1 is used to perform deep heating on the pole piece 400 to reduce the internal stress and rebound of the pole piece 400. The cooling module 2 is used to cool the heated pole piece 400.

[0053] The first heating module 1 includes a first heating component 110 and a second heating component 120, which are arranged opposite to each other and a gap is left between the first heating component 110 and the second heating component 120 for the pole piece 400 to pass through. During use, the pole piece 400 passes through the gap between the first heating component 110 and the second heating component 120, and both sides thereof are heated to improve the heating efficiency and make it evenly heated.

[0054] The first heating assembly 110 and the second heating assembly 120 each include a plurality of heating units 130 arranged along the running direction of the pole piece 400. The heating units 130 may be arranged in close contact with each other, or there may be a gap between them. The specific design method is set according to the actual situation. Among them, the heating unit 130 includes a focusing lamp tube 131 and a focusing lamp cover 132. The focusing lamp cover 132 is provided with a reflective arc surface 132a. The focusing lamp tube 131 is arranged in the reflective arc surface 132a so that the focusing lamp tube 131 focuses the heating light to the pole piece 400. The focusing lamp cover 132 can reflect the heating light. The focusing lamp cover 132 can be a material with reflective properties such as metal, glass, lens, etc., and its reflective surface is a parabola or an elliptical surface. The focusing lamp tube 131 can be an infrared lamp tube, a quartz lamp tube, a carbon fiber heating tube, etc., which have heating properties. This embodiment is not limited here. A reflecting arc surface 132a is arranged inside the focusing lampshade 12, and the focusing lamp tube 11 is arranged inside the reflecting arc surface 132a. The reflecting arc surface 132a selects a suitable reflection curvature according to actual conditions, so that the heating light of the focusing lamp tube 11 is refracted through the reflecting arc surface 132a and irradiated vertically on the pole piece 200, thereby achieving heating of the pole piece 200 (as shown by the dotted line in 4 in the accompanying drawing).

[0055] The cooling module 2 includes a plurality of water-cooled rollers 210 to cool the pole piece 400 heated by the first heating module 1. The number of water-cooled rollers 210 may be 1 / 2 / 3 / 4, etc., which is not specifically limited in this embodiment. The pole piece 400 may be lowered to an appropriate temperature by a plurality of water-cooled rollers 210.

[0056] During use, the electrode piece 400 enters the oven through the first roller 200, and is transferred to the first heating module 1 through the roller. At this time, the focusing lamp tube 131 reflects the heating light to the electrode piece 400 through the reflective arc surface 132a, and heats both sides of the electrode piece 400. Subsequently, the heated electrode piece 400 enters the cooling module 2, and is cooled by multiple water-cooled rollers 210, and then is transferred to the next process through the second roller 300.

[0057] The energy-concentrating oven of the present embodiment heats the electrode 400 by setting a first heating module 1. The energy-concentrating lamp tube 131 and the energy-concentrating lamp cover 132 can make the light emitted by the energy-concentrating lamp tube 131 shine parallel on the electrode 400. According to actual experiments, parallel light irradiation can evenly illuminate the electrode, and continuous heating and temperature increase make the temperature more penetrating, and heat both sides of the electrode 400. The heating temperature consistency is high, which can effectively reduce the internal stress and rebound of the electrode 400 and achieve deep baking or curing effect. At the same time, a number of water-cooling rollers 210 are provided to cool the electrode 400, accelerate its cooling speed, and improve production efficiency.

[0058] Example 2

[0059] The difference between Example 2 and Example 1 is that the oven is further optimized in this example. Figure 3-4 As shown, further, a second heating module 3 is provided between the cooling module 2 and the first module, and the heating temperature of the second heating module 3 is greater than the heating temperature of the first heating module 1. A gap is left between the second heating module 3 and the first heating module 1, which is used to perform secondary heating on the pole piece 400, further reducing the internal stress and rebound of the pole piece 400. The second heating module 3 can be arranged in a similar manner to the first heating module 1, and it can also be heated by other existing methods, such as blowing hot air, using heating lamps, etc. The second heating module 3 performs two-stage heating on the pole piece 400, and its heating temperature is preferably one times that of the first heating module 1. Exemplarily, the first heating module 1 heats the pole piece 400 to 100-200°C, and the second heating module 3 heats the pole piece 400 to 300-400°C, reducing the internal stress and rebound of the pole piece 400 and improving the quality of the pole piece 400.

[0060] In some embodiments, an air-cooled roller 410 assembly 4 for transmitting the pole piece 400 is provided between the first heating module 1 and the second heating module 3; the air-cooled roller 410 assembly 4 includes an air-cooled roller 410, a pneumatic joint 420 and a rotating drive member, the pneumatic joint 420 is connected to the air-cooled roller 410, and the rotating drive member is connected to the air-cooled roller 420 by transmission, driving the air-cooled roller 420 to rotate. The rotating drive member can be a motor, a servo gear, etc., and the pole piece can be actively rolled by setting the rotating drive member to overcome the problem of the small wrap angle of the pole piece of the air-cooled roller. Solenoid valves and regulating valves can also be provided, and the air intake is controlled by the solenoid valve, and the pressure regulating valve controls the pressure, and the air-cooled roller is monitored and cooled, and the temperature is detected. Exemplarily, a specific setting method is provided, the rotating drive member is a servo motor, and the driving end of the servo motor is connected to a reducer, and one end of the air-cooled roller 420 is connected to the driving end of the reducer through a synchronous belt, thereby driving the air-cooled roller 420 to rotate. A pneumatic joint 420 is provided on one side of the air-cooled roller 410. The pneumatic joint 420 is connected to an external blower, fan, etc., and transmits the airflow generated externally to the air-cooled roller 410 to cool it down. This prevents the heated pole piece 400 from directly passing through the roller, which will transfer heat to the air-cooled roller 410 and affect the service life of other parts. A temperature sensor can also be provided on the air-cooled roller 410 to detect its temperature change in real time and feed back the temperature signal.

[0061] In some embodiments, a heat dissipation module 5 for cooling the first heating module 1 is also included; the heat dissipation module 5 includes a first heat dissipation pipe 510 and a water cooler 520 connected to the heat dissipation pipe, and the first heat dissipation pipe 510 is arranged in the energy-concentrating lampshade 132 to dissipate heat from the energy-concentrating lampshade 132. The heat dissipation pipe is arranged on one side of the energy-concentrating lampshade 132, and includes a water inlet and a water outlet. The water cooler 520 is used to provide cooling liquid for the heat dissipation pipe, and the cooling liquid flows into the water inlet and flows out of the water outlet. The water cooler 520 transmits the cooling liquid to the heat dissipation cover through the heat dissipation pipe, and cools down the first heating module 1 through the flow of the cooling liquid to prevent the internal temperature from being too high. By setting up a water cooling method, the cooling efficiency is higher, the service life of the energy-concentrating lamp tube 131 and the energy-concentrating lampshade 132 is increased, and at the same time, the heat is prevented from being conducted away and affecting other components.

[0062] Exemplarily, the heat dissipation module 5 may also include detection equipment such as a pressure gauge, a thermometer, and a flow meter, which are arranged on the first heat dissipation tube 510 to detect the pressure, temperature, and flow of the coolant in the first heat dissipation tube 510 in real time to facilitate control of the water cooling system.

Figure 6-7As shown, further, the cooling module 2 also includes a first drive component 220 and a second heat dissipation pipe 230. The first drive component 220 is connected to the water-cooled roller 210 to drive the water-cooled roller 210 to rotate; the second heat dissipation pipe 230 is arranged in the water-cooled roller 210 to cool the water-cooled roller 210. The second heat dissipation pipe 230 is connected to an external water-cooling machine 520 and other equipment to transmit the coolant to the second heat dissipation pipe 230. The coolant flows on the water-cooled roller 210 along the second heat dissipation pipe 230, thereby cooling the water-cooled roller 210. The first drive component 220 can be a drive motor, a steering gear and other equipment. Exemplarily, the first drive component 220 is a servo motor, which is connected to the water-cooled roller 210 through a reducer, drives the water-cooled roller 210 to rotate, and actively rolls the pole piece 400.

[0065] It is understandable that the cooling module 2 may also include detection equipment such as a pressure gauge, a thermometer, and a flow meter, which are arranged on the second heat dissipation pipe 230 to detect the pressure, temperature, and flow of the coolant in the second heat dissipation pipe 230 in real time to facilitate the control of the water cooling system.

[0066] Preferably, it also includes a pressure roller 6 and a second drive assembly 7 that is transmission-connected to the pressure roller 6; the pressure roller 6 is arranged on one side of the water-cooled roller 210, and the second drive assembly 7 can drive the pressure roller 6 to approach or move away from the water-cooled roller 210. Among them, the second drive assembly 7 is a cylinder, which is arranged at both ends of the pressure roller 6, and the pressure roller 6 is driven to move by extending the cylinder. The pressure roller 6 is a rubber pressure roller 6, which can prevent the pole piece 400 from being damaged when pressed. The pressure roller 6 cooperates with the water-cooled roller 210 to achieve the isolation of the tension of the pole piece 400 and realize the tension closed loop. When the pole piece 400 is threaded, the cylinder opens and the pole piece 400 passes through the pressure roller 6; when the threading is completed, the pressure roller 6 is pressed down to achieve tension isolation.

The swing arm 820 is arranged at both ends of the swing roller 810, and the swing arm 820 is a block structure. The two ends of the rotating shaft 840 are connected to the other side of the swing arm 820, and the rotating shaft 840 and the swing roller 810 are arranged opposite to each other, and there is a gap between them. By rotating the rotating shaft 840, the swing roller 810 can be driven to move through the swing arm 820. The third drive assembly 830 can be a motor, a steering gear, a cylinder, etc. Exemplarily, the third driving assembly 830 is a cylinder, the output end of which is connected to one end of a connecting rod, and the other end of the connecting rod is connected to the rotating shaft 840. The cylinder is extended and retracted to drive the rotating shaft 840 to rotate. It may also include an angle sensor to detect the angle of rotation of the rotating shaft 840, so as to finely control the tension of the pole piece 400. During use, the pole piece 400 passes through the swing roller 810, and the third driving assembly 830 drives the rotating shaft 840 to rotate, thereby driving the swing roller 810 to rotate, tightening or loosening the pole piece 400, so as to control its tension.

[0069] In some embodiments, the tension control assembly 8 further includes a tension detection sensor 850 for detecting the tension of the pole piece 400. A roller may be provided on one side of the swing roller 810, and the tension detection sensor 850 is provided on the roller, and the tension detection sensor 850 is a tension meter.
