Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery processing technology, and in particular to an adjustable heating device for electrode tabs. Background Technology
[0002] Tabs are a key component of lithium-ion polymer batteries, primarily used to draw positive and negative electrodes from the battery cell, ensuring smooth current flow and supporting normal battery operation. A complete tab structure consists of two films sandwiching a metal strip in between. During tab manufacturing, a heating device is used to heat the tab films to bond them to the metal strip.
[0003] Chinese patent CN217891903U discloses a heating device for preventing bubbling by pressing tabs together. The device includes a mounting frame. A drive motor is fixedly mounted on the bottom left side of the mounting frame, and the output shaft of the drive motor extends into the mounting frame and is fixedly mounted on a supporting heating roller. The right end of the supporting heating roller is rotatably connected to the inner wall of the bottom right side of the mounting frame. A movable frame is longitudinally slidably connected within the mounting frame, and a movable heating roller is rotatably connected within the movable frame. Temperature sensors are fixedly mounted on the right ends of both the supporting heating roller and the movable heating roller. The bottom of the movable heating roller extends below the movable frame. A transmission assembly is mounted on the top of the movable frame and is connected to the inner wall of the top of the mounting frame.
[0004] In the above-mentioned heating device, a transmission component is used to move the moving electric heating roller downwards, pressing the tab rubber and metal strip onto the supporting electric heating roller. However, the transmission component has a complex structure and is controlled by an electric push rod, making it inconvenient to adjust the pressing force of the moving electric heating roller. Moreover, the cost is high, and the heat generated by the moving electric heating roller and the supporting electric heating roller will be wasted. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Please see Figure 1-4 This utility model provides an adjustable heating device with adjustable tabs, comprising:
[0030] Heating box 1, with a feed inlet on one side wall and a discharge outlet on the other side wall;
[0031] Active electric heating roller 2 is rotatably disposed between the inner walls of both sides of the heating box 1;
[0032] Drive motor 3 is fixedly installed on one side of the outer wall of heating box 1, and the output shaft of drive motor 3 is fixedly connected to one end of active electric heating roller 2.
[0033] Support 4 is installed inside heating box 1, and driven electric heating roller 41 is rotatably provided between the inner walls on both sides of support 4;
[0034] Adjustment mechanism 5 is installed on heating box 1 and is used to adjust the height of driven electric heating roller 41;
[0035] The preheating mechanism 6 is installed on the heating box 1 and is used to preheat the tab film entering the heating box 1.
[0036] With the above-described structure, the height of the driven electric heating roller 41 can be adjusted in a simpler way, which is cost-effective and more practical. In addition, the heat emitted by the driven electric heating roller 41 and the active electric heating roller 2 is used to preheat the tab film, thus avoiding heat waste.
[0037] The adjusting mechanism 5 includes a threaded sleeve 51, which is fixedly embedded in the upper side wall of the heating box 1. An adjusting screw 52 is threadedly connected to the inner side of the threaded sleeve 51. A handwheel 53 is fixedly connected to the upper end of the adjusting screw 52, and the lower end is rotatably connected to the bracket 4.
[0038] With the above structure, the height of the driven heating roller 41 can be adjusted, so that the driven heating roller 41 can press the tab film and metal strip onto the active heating roller 2. The structure is simpler and easier to control the pressing force of the driven heating roller 41.
[0039] The preheating mechanism 6 includes a fan 61, which is fixedly installed on the upper outer wall of the heating box 1. The air inlet of the fan 61 is connected to an air inlet pipe 63, and the other end of the air inlet pipe 63 is connected to the inside of the heating box 1. The air outlet of the fan 61 is connected to an exhaust pipe 64. An exhaust hood 62 is fixedly connected to the outer wall of the heating box 1 near the feed inlet, and the other end of the exhaust pipe 64 is connected to the exhaust hood 62.
[0040] With the above structure, the heat emitted into the heating box 1 by the driven electric heating roller 41 and the active electric heating roller 2 can be used to preheat the tab film entering the heating box 1, thereby accelerating its softening speed and improving heating efficiency.
[0041] In this heating box 1, a limiting rod 42 is slidably inserted on the upper side wall and on both sides of the adjusting screw 52. The lower end of the limiting rod 42 is fixedly connected to the bracket 4. The limiting rod 42 can limit and guide the bracket 4 so that it will not rotate.
[0042] The lower side wall of the exhaust hood 62 is equipped with a dustproof net 621 to filter dust in the hot air and prevent dust in the production environment from affecting the tab film.
[0043] The outer sides of both the active heating roller 2 and the driven heating roller 41 are covered with a flexible heat-conducting layer 7. The flexible heat-conducting layer 7 can be made of flexible materials with good thermal conductivity, such as silicone or graphene composite materials. The flexible heat-conducting layer 7 can prevent the rigid extrusion of the active heating roller 2 and the driven heating roller 41 from causing indentations on the electrode tabs.
[0044] It should be noted that this utility model is an adjustable electrode heating device. In use, after the electrode film is applied to the metal strip, the metal strip and electrode film are fed into the heating chamber 1 through the feed inlet. Then, the handwheel 53 is turned to drive the adjusting screw 52 to rotate. When the adjusting screw 52 rotates, under the action of the threaded sleeve 51, it pushes the bracket 4 to move downwards under the limit of the limiting rod 42, so that the driven electric heating roller 41 presses the electrode film and metal strip tightly onto the active electric heating roller 2. The output shaft of the drive motor 3 drives the active electric heating roller 2 to rotate, thus... The tab film and metal strip move together. During the movement, the active heating roller 2 and the driven heating roller 41 heat the tab film to soften it and press it firmly onto the metal strip. During the heating process, the blower 61 uses the air inlet pipe 63 to extract the hot air from the heating box 1 and sends it to the exhaust hood 62 through the exhaust pipe 64. After being filtered by the dustproof net 621, the hot air is blown onto the tab film to preheat it, accelerate the softening speed of the tab film, and improve the heating efficiency. The hot-pressed tab is discharged from the heating box 1 through the discharge port.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
