Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a battery cell body wrapping device and equipment. Background Technology

[0002] In modern electronic devices, lithium batteries, as a highly efficient and lightweight energy solution, are widely used in various portable devices and electric vehicles. The performance and safety of lithium batteries directly affect the quality of the final product and the safety of the user. Therefore, the manufacturing process of lithium batteries requires strict control to ensure their performance and safety.

[0003] The assembly process of lithium batteries involves several key steps, among which adhesive application (also known as wrapping) is a crucial step in ensuring battery safety and stability. The adhesive application process mainly involves attaching specific adhesive tapes to specific parts of the battery, such as the outer surface of the cell, electrodes, and tabs. These tapes are typically made of materials with high adhesion and good insulation properties, such as polypropylene (PP) and polyester (PET).

[0004] Two types of tape are typically used during the application of adhesive:

[0005] Continuous adhesive tape: This is a long strip of tape, usually available in rolls, that can be cut to the required length and width. Continuous adhesive tape requires precise control during use to ensure accurate and even application.

[0006] Sheet adhesive tape: These are pre-cut sheets of adhesive tape in specific shapes and sizes, which can be quickly and accurately applied to specific parts of the battery, improving production efficiency.

[0007] However, the adhesive application process faces numerous challenges in actual battery assembly. Because the outer surface of the cell body needs to be wrapped with adhesive on multiple sides (four outer surfaces), operators may encounter uneven or misaligned application when applying the tape. These problems can lead to incomplete tape coverage, leaving unprotected areas and increasing the risk of battery short circuits. Furthermore, uneven adhesive application can also affect battery thermal management, causing uneven heat generation during charging and discharging, impacting battery performance and lifespan.

[0026] Furthermore, the retracting assembly includes a first retracting member, a first retracting driver, a second retracting member, and a second retracting driver;

[0027] The first gathering member and the second gathering member are arranged facing each other in the clamping direction of the cell clamping assembly;

[0029] The second retractor is connected to the second retractor and is used to drive the second retractor to move away from or closer to the first retractor.

[0030] Furthermore, the retractable assembly also includes a first elastic element and a second elastic element;

[0031] The first retractable component is hinged to the first retractable driver;

[0043] Furthermore, it also includes detection devices;

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0057] This application discloses a battery cell body wrapping device and equipment.

[0058] Please see Figure 1 One embodiment of the battery cell body wrapping device provided in this application includes:

[0059] The battery cell clamping assembly 3, the first adsorption assembly 1, the second adsorption assembly 2, and the gathering assembly 4.

[0060] The cell clamping assembly 3 is provided with a clamping cavity for clamping the cell body 6.

[0061] The first adsorption component 1 is located on one side of the clamping cavity, and its adsorption end can move through the clamping cavity and is used to adsorb the tape 7 to be wrapped; the second adsorption component 2 is located on the other side of the clamping cavity, and its adsorption end can move away from or close to the adsorption end of the first adsorption component 1 and is used to adsorb the battery cell body 6.

[0062] The gathering component 4 is located on the other side of the clamping cavity and is used to press the tape onto the other side of the battery cell body 6 away from the first adsorption component 1.

[0063] The cell clamping assembly 3 can clamp the cell body 6 from the left and right sides. Correspondingly, the first adsorption assembly 1 is located on the upper side of the clamping cavity, while the second adsorption assembly 2 is located on the lower side of the clamping cavity.

[0064] The battery cell body wrapping device designed in this application includes the following wrapping process: First, the first adsorption component 1 and the second adsorption component 2 are driven to make the battery cell body 6 adsorbed by the second adsorption component 2 tightly adhere to the adhesive tape 7 to be wrapped, completing the adhesive application on the first surface of the battery cell body 6; then, the first adsorption component 1 and the second adsorption component 2 are driven to move the battery cell body 6 into the clamping cavity (e.g., Figure 4 (See the schematic diagram of state a in the diagram). During the process of entering the clamping cavity, the adhesive tape 7 to be wrapped at both ends of the battery cell body 6 will be wrapped around both sides of the battery cell body 6. Subsequently, the battery cell clamping assembly 3 is driven to clamp the battery cell body 6, completing the adhesive application on the other two sides; then, the adsorption end of the second adsorption assembly 2 is driven to move away from the first adsorption assembly 1 by a certain distance, and finally the gathering assembly 4 is driven to adhere the remaining portion of the adhesive tape 7 to the fourth side of the battery cell body 6, thereby completing the adhesive wrapping on all four sides of the battery cell body 6 (as shown in the diagram of state a in the diagram). Figure 4 (See the schematic diagram of state b in the diagram). Through the coordinated movement of the cell clamping component 3, the first adsorption component 1, the second adsorption component 2, and the gathering component 4, the glue wrapping process of the cell body 6 is realized, which effectively solves the problem of uneven or misaligned glue wrapping, thereby improving the quality of the cell.

[0065] The above is Embodiment 1 of the battery cell body winding device provided in this application. The following is Embodiment 2 of the battery cell body winding device provided in this application. Please refer to the following for details. Figures 1 to 5 .

[0066] Based on the solution of Embodiment 1 above:

[0067] Furthermore, such as Figure 1 As shown, the design of the first adsorption component 1 includes a first vacuum adsorption element 12, a first vacuum pump (not shown), and a first adsorption driver 11. One end of the first vacuum adsorption element 12 has several first adsorption holes, forming an adsorption end. The first vacuum pump is connected to the first adsorption holes. The first adsorption driver 11 is connected to the first vacuum adsorption element 12 and is used to drive the first vacuum adsorption element 12 to move. The first vacuum adsorption element 12 can be a vacuum plate with several evenly distributed first adsorption holes to enhance the adsorption effect and ensure that the tape 7 to be wound can be stably adsorbed. The first vacuum pump is connected to the first adsorption holes through a pipe. When the first vacuum pump is started, it can generate negative pressure through the first adsorption holes, thereby adsorbing the tape 7 to be wound onto the first vacuum adsorption element 12. The first adsorption driver 11 is connected to the first vacuum adsorption element 12 and is used to drive the first vacuum adsorption element 12 to move, so as to accurately place the tape 7 to be wound at a designated position on the battery cell body 6.

[0068] The first adsorption actuator 11 can be a linear module or a telescopic cylinder. Both types of actuators have the ability to precisely control the position of the first vacuum adsorption component 12. The linear module, through the cooperation of a linear guide and a lead screw, can achieve high-precision linear motion and is suitable for scenarios requiring high positional accuracy. The telescopic cylinder, on the other hand, uses pneumatic pressure to drive a piston rod for telescopic movement, featuring a simple structure and rapid action, making it suitable for scenarios requiring a certain speed of movement. In practical applications, the appropriate actuator type can be selected based on the specific needs and working environment of the battery cell winding device.

[0069] Furthermore, such as Figure 1 As shown, the design of the second adsorption component 2 includes a second vacuum adsorption element 22, a second vacuum pump (not shown), and a second adsorption actuator 21. One end of the second vacuum adsorption element 22 has several second adsorption holes, forming an adsorption end. The second vacuum pump is connected to the second adsorption holes. The second adsorption actuator 21 is connected to the second vacuum adsorption element 22 and is used to drive the second vacuum adsorption element 22 to move. The second vacuum adsorption element 22 can be a vacuum plate.

[0070] The device has several evenly distributed second adsorption holes for adsorbing the battery cell body 6. A second vacuum pump is connected to the second adsorption holes through a pipe. When the second vacuum pump is started, it can generate negative pressure through the second adsorption holes, thereby stably adsorbing the battery cell body 6 onto the second vacuum adsorption member 22. The second adsorption actuator 21 is connected to the second vacuum adsorption member 22 and is used to drive the second vacuum adsorption member 22 to move so that the battery cell body 6 can be accurately placed in a designated position. Similar to the first adsorption actuator 11, the second adsorption actuator 21 can also be a linear module or a telescopic cylinder to meet different motion control requirements.

[0071] Furthermore, such as Figure 1 as well as Figure 2 As shown, the design of the battery cell clamping assembly 3 includes a first clamping member 31, a first clamping driver 32, a second clamping member 33, and a second clamping driver 34; the first clamping member 31 and the second clamping member 33 are arranged facing each other and form a clamping cavity between them; the first clamping driver 32 is connected to the first clamping member 31 and is used to drive the first clamping member 31 to move away from or closer to the second clamping member 33; the second clamping driver 34 is connected to the second clamping member 33 and is used to drive the second clamping member 33 to move away from or closer to the first clamping member 31.

[0072] The first clamping member 31 and the second clamping member 33 can be clamping structures such as claws or clamping plates. Driven by the first clamping driver 32 and the second clamping driver 34, they achieve the clamping and release of the battery cell body 6. The first clamping driver 32 and the second clamping driver 34 can also be linear modules or telescopic cylinders to ensure that the battery cell body 6 can be clamped and released stably and accurately. During the glue wrapping process of the battery cell body 6, the battery cell clamping assembly 3 serves to fix the battery cell body 6, ensuring that the battery cell body 6 does not move or misalign during the glue wrapping process, thereby improving the accuracy and quality of the glue wrapping; it also serves to adhere the glue tape 7 to both sides of the battery cell.

[0073] Furthermore, such as Figures 1 to 3 As shown, the gathering assembly 4 includes a first gathering member 41, a first gathering driver 42, a second gathering member 43, and a second gathering driver 44; the first gathering member 41 and the second gathering member 43 are arranged facing each other in the clamping direction of the cell clamping assembly 3; the first gathering driver 42 is connected to the first gathering member 41 and is used to drive the first gathering member 41 to move away from or towards the second gathering member 43; the second gathering driver 44 is connected to the second gathering member 43 and is used to drive the second gathering member 43 to move away from or towards the first gathering member 41.

[0074] The first gathering component 41 and the second gathering component 43 can be structures such as pressure blocks or pressure plates. Driven by the first gathering driver 42 and the second gathering driver 44, they press the adhesive tape 7 to be wrapped onto the battery cell body 6. The first gathering driver 42 and the second gathering driver 44 can also be drivers such as linear modules or telescopic cylinders to ensure that the adhesive tape 7 to be wrapped can be stably and accurately pressed onto the designated position of the battery cell body 6. After the adhesive tape is wrapped on three sides of the battery cell body 6, the gathering component 4 can attach the remaining adhesive tape to the fourth side of the battery cell body 6.

[0075] The first gathering member 41 and the second gathering member 43 have rounded corners at their opposite ends. This design is primarily to reduce friction and damage to the battery cell body 6 or the adhesive tape during the gathering process. The rounded corners allow for a smoother transition when the gathering members contact the battery cell body 6 or the adhesive tape, preventing stress concentration or scratching, thus protecting the surface quality of the battery cell body 6 and ensuring that the adhesive tape adheres tightly and evenly to the battery cell body 6. Furthermore, the rounded corners also help improve the smoothness of the movement of the gathering assembly 4, reduce resistance and noise during movement, and improve the overall performance and stability of the battery cell body wrapping device.

[0076] Furthermore, such as Figure 2 as well as Figure 5 As shown, the retracting assembly 4 also includes a first elastic member and a second elastic member; the first retracting member 41 is hinged to the first retracting driver 42; the first elastic member is connected to the first retracting member 41 and is used to provide an elastic force that drives the first retracting member 41 to rotate toward the clamping assembly when the first retracting member 41 moves toward the second retracting member 43; the second retracting member 43 is hinged to the second retracting driver 44; the second elastic member is connected to the second retracting member 43 and is used to provide an elastic force that drives the second retracting member 43 to rotate toward the clamping assembly when the second retracting member 43 moves toward the first retracting member 41.

[0077] The first and second elastic elements can be tension springs, which respectively pull the first gathering member 41 and the second gathering member 43. When the first gathering member 41 and the second gathering member 43 move towards each other, the tension springs are stretched, providing elastic force for the first gathering member 41 and the second gathering member 43 to press against the clamping assembly. This allows the first gathering member 41 and the second gathering member 43 to press against the tape as they move towards each other, thus pressing the tape tightly against the fourth surface of the battery cell body 6, ensuring the adhesion between the tape and the battery cell body 6, and improving the wrapping quality. The first and second elastic elements can also mitigate the adverse effects caused by differences in the size of the battery cell body 6 or changes in tape tension to a certain extent, giving the battery cell body wrapping device better adaptability and stability. After the cell body 6 is wrapped with glue, the first gathering driver 42 and the second gathering driver 44 can drive the first gathering member 41 and the second gathering member 43 away from the cell body 6. At this time, the first elastic member and the second elastic member will drive the first gathering member 41 and the second gathering member 43 to reset, preparing for the next glue wrapping operation.

[0078] Furthermore, such as Figure 1 As shown, it also includes a loading / unloading displacement component 5; the loading / unloading displacement component 5 is connected to the second adsorption component 2 and is used to drive the second adsorption component 2 to move.

[0079] The design of the loading / unloading displacement assembly 5 enables the battery cell body 6 to be transferred between different stations of the adhesive winding device. Specifically, the loading / unloading displacement assembly 5 may include components such as a displacement driver and a displacement track. The displacement driver drives a slider or transmission belt on the displacement track to move the second adsorption assembly 2 up and down or left and right. In this way, after the battery cell body 6 completes the adhesive winding operation, the loading / unloading displacement assembly 5 can drive the second adsorption assembly 2 to move the battery cell body 6 from the adhesive winding station to the unloading station, realizing an automated production process and improving production efficiency.

[0080] Furthermore, such as Figure 1 As shown, the cell clamping assembly 3 is mounted on the first adsorption assembly 1; the gathering assembly 4 is mounted on the cell clamping assembly 3. This design makes the structure of the entire cell body wrapping device more compact and the coordinated movement between the components more efficient.

[0081] Taking the gathering component 4 installed on the cell clamping component 3 as an example, the first clamping member 31 and the second clamping member 33 of the cell clamping component 3 can be designed in an L-shape. The first gathering driver 42 and the second gathering driver 44 are respectively installed on the first clamping member 31 and the second clamping member 33, and their driving ends are respectively connected to the first gathering member 41 and the second gathering member 43. One end of the first elastic member is connected to the first gathering member 41, and the other end is connected to the first clamping member 31. One end of the second elastic member is connected to the second gathering member 43, and the other end is connected to the second clamping member 33.

[0082] like Figure 6 As shown, this application also discloses a battery cell body 6 winding device, including a glue supply device 100, a glue transfer device 200, and a battery cell body winding device 300.

[0083] The adhesive supply device 100 is used to supply the tape 7 to be wound. The adhesive supply device 100 can be a continuous tape supply design or a sheet-by-sheet supply design. If a continuous tape supply design is used, a feed roll 101 and a waste roll 102 are required, as well as cutting and adhesive removal. If a sheet-by-sheet supply design is used, a feed roll 101 and two waste rolls 102 are required.

[0084] The waste roll 102 can be designed to be detachable to accommodate quick changeover requirements (continuous tape supply or sheet-by-sheet supply switching).

[0085] The adhesive transfer device 200 is disposed between the adhesive supply device 100 and the cell body winding device 300, and is used to transfer the adhesive tape 7 to be wound supplied by the adhesive supply device 100 to the cell body winding device 300; the cell body winding device 300 is used to wrap the adhesive tape 7 to be wound around the cell body 6.

[0086] The adhesive transfer device 200 can be a multi-axis robot, without any restrictions.

[0087] Furthermore, it also includes a detection device 400, which is used to detect the battery cell body 6 wrapped with tape. The detection device 400 may include detection elements such as sensors and cameras (CCD) to detect the battery cell body 6 wrapped with tape to ensure the quality of tape wrapping.

[0088] The above provides a detailed description of the battery cell body wrapping device and equipment provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
