For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0024] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0026] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0027] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0032] Prior to this application, traditional methods for coating steel-cased battery cells mostly involved manual operation or semi-automatic equipment, which was not only inefficient but also difficult to guarantee the consistency and reliability of the coating.

[0033] In view of this, according to the first aspect of this application, a battery cell coating device is provided, thereby solving the problems of low efficiency and difficulty in ensuring the consistency and reliability of coating in traditional steel-cased battery cell coating methods. Referring below... Figures 1 to 8 This application describes a battery cell coating apparatus according to some embodiments.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the battery cell coating device of this application includes a controller, a battery cell fixing mechanism 500, a lifting drive unit 100, a lifting slide 200, two linear drive mechanisms 300, and two glue scraping mechanisms 400. The battery cell fixing mechanism 500 is used to fix the battery cell. The lifting drive unit 100 is connected to the lifting slide 200 to drive the lifting slide 200 to slide along the Z direction. Two linear drive mechanisms 300 are connected to the side of the lifting slide 200 facing the battery cell fixing mechanism 500. The two linear drive mechanisms 300 are symmetrically arranged about the center line of the lifting slide 200, and the center line is parallel to the Z direction. The linear drive mechanism 300 includes a first drive unit 310 and a first slide 320. The first drive unit 310 can drive the first slide 320 to slide along the X direction. Two adhesive scraping mechanisms 400 are respectively connected to the side of the two first slides 320 facing the battery cell fixing mechanism 500. The two adhesive scraping mechanisms 400 can attach adhesive paper to the two opposite sides of the battery cell in the X direction. The controller is communicatively connected to the lifting drive unit 100 and the first drive unit 310.

[0035] In other words, the cell coating device of this application completes the coating process through automated control, that is, the adhesive tape is attached to the two opposite sides of the cell in the X direction.

[0036] Specifically, the battery cell fixing mechanism 500 of this application fixes the battery cell. When the battery cell arrives, the adhesive tape on it is in the shape of a "U". Initially, the controller controls the lifting drive unit 100 to drive the lifting slide 200 to slide along the Z direction, which in turn drives the two linear drive mechanisms 300 and the two adhesive scraping mechanisms 400 to slide along the Z direction. First, the two adhesive scraping mechanisms 400 reach the initial position (the surface of the adhesive tape). Then, the controller controls the first drive unit 310 of the two linear drive mechanisms 300 to drive the first slide 320 to slide along the X direction, which in turn drives the two adhesive scraping mechanisms 400 to slide along the X direction (the positive and negative directions of X, respectively), smoothing the "U" adhesive tape into the shape of an "I". Finally, the controller controls the lifting drive unit 100 to drive the lifting slide 200 to continue sliding along the Z direction, which in turn drives the two adhesive scraping mechanisms 400 to scrape the "I" shape to both sides, forming a "U" shape, so as to attach the adhesive tape to the two opposite sides of the battery cell in the X direction.

[0037] The battery cell coating device of this application controls the lifting drive unit 100 and the first drive unit 310 through a controller to automatically complete the coating process. Compared with the prior art, this automatic control not only improves production efficiency and reduces manual intervention, but also significantly improves the consistency and reliability of the product.

[0038] Additionally, in the embodiments of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the battery cell coating device of this application also includes two electric rotary tables 800; the two electric rotary tables 800 are respectively connected to one side of the two first slides 320 facing the battery cell fixing mechanism 500, and the two electric rotary tables 800 are symmetrically arranged about the center line of the lifting slide 200. Figure 6 As shown, the electric rotary table 800 includes a second drive unit 810 and a rotary table 820. The rotary table 820 is positioned facing the battery cell fixing mechanism 500. Two adhesive scraping mechanisms 400 are respectively connected to the two sides of the rotary table 820 facing the battery cell fixing mechanism 500. The second drive unit 810 can drive the rotary table 820 to rotate, thereby driving the adhesive scraping mechanisms 400 to rotate. The controller is communicatively connected to the second drive unit 810. It should be noted that the electric rotary table 800 is prior art and is a readily available product.

[0039] With this setup, during the coating process, after the two adhesive scraping mechanisms 400 reach their initial positions (on the adhesive paper surface), the controller controls the first drive unit 310 of the two linear drive mechanisms 300 to drive the first slide 320 to slide along the X direction, thereby driving the two electric rotary tables 800 and the two adhesive scraping mechanisms 400 to slide along the X direction (the positive and negative directions of X, respectively), smoothing the "U"-shaped adhesive paper into an "I" shape. During this process, to ensure the accuracy of the coating, the controller can also control the second drive unit 810 to drive the adhesive scraping mechanism 400 to rotate, further smoothing the adhesive paper into an "I" shape. Finally, the controller controls the lifting drive unit 100 to drive the lifting slide 200 to continue sliding along the Z direction, smoothing the "I" shape to both sides into a "U" shape, so that the adhesive paper is attached to the opposite sides of the battery cell in the X direction.

[0040] The following will describe in detail the specific structure of the cell fixing mechanism 500, the linear drive mechanism 300, the electric rotary table 800 and the glue scraping mechanism 400 of this application, as well as the glue coating process.

[0041] In the embodiments of this application, such as Figure 4 and Figure 5 As shown, the linear drive mechanism 300 also includes a lead screw 330, a nut 340, and a fixed platform 350. The first drive unit 310 is a drive motor. The fixed platform 350 is fixedly connected to the lower part of the lifting slide 200. The first drive unit 310 is connected to the lead screw 330, which is threadedly connected to the nut 340. The lower part of the nut 340 is fixedly connected to the first slide 320. The first slide 320 and the fixed platform 350 are slidably connected via ball bearings. Thus, the first drive unit 310 drives the lead screw 330 to rotate, thereby causing the nut 340 to move along the lead screw 330, and consequently causing the first slide 320 to slide along the X direction on the fixed platform 350. It should be noted that the first drive unit 310 should be in a fixed state, meaning it can be fixed to other components, which are not shown in the figure.

[0042] In the embodiments of this application, such as Figure 6 As shown, the adhesive scraping mechanism 400 includes an adhesive scraper 410, a support plate 420, a first sliding plate 430, a first fixed plate 440, and a first spring 450. In the initial state, the support plate 420 extends along the Z-direction and is connected to the rotary table 820. The first sliding plate 430 is slidably connected to one side of the support plate 420 in the Y-direction (via a slide rail and slider). The first fixed plate 440 is fixedly connected to one side of the support plate 420 in the Y-direction. The first spring 450 extends along the X-direction and is fixed between the first fixed plate 440 and the first sliding plate 430. The adhesive scraper 410 is connected to the first sliding plate 430 and extends along the Z-direction. This configuration allows the first spring 450 to provide a flexible buffering and pressing effect, preventing the adhesive scraper 410 from directly and rigidly contacting and damaging the battery cell. In addition, in the initial state, the two scraper plates 410 of the two scraper mechanisms 400 are symmetrically arranged, and the two large surfaces of the two scraper plates 410 face each other, which makes it convenient for the scraper plates 410 to smooth or flatten the adhesive paper.

[0043] In the embodiments of this application, such as Figure 7 As shown, the battery cell coating device of this application further includes a third drive motor, a turntable 600, and a fixed plate 700; the battery cell fixing mechanism 500 includes a battery cell support platform 510, a fourth drive unit 520, and a pressing unit 530. The third drive motor is connected to the turntable 600 to drive the turntable 600 to rotate, and the fixed plate 700 is fixed above the turntable 600; the battery cell support platform 510 is fixed on the turntable 600, and the fourth drive unit 520 is fixed on the fixed plate 700. The fourth drive unit 520 can drive the pressing unit 530 to move along the Z direction to press the battery cell against the corresponding battery cell support platform 510; the controller is communicatively connected to the fourth drive unit 520 and the third drive motor.

[0044] In the embodiments of this application, such as Figure 7 As shown, there are four battery cell fixing mechanisms 500, which correspond sequentially to the battery cell loading position, the battery cell adhesive tape detection position, the battery cell coating position, and the battery cell unloading position. When the battery cell moves to the coating position with the turntable 600, the controller controls the fourth drive unit 520 to drive the clamping unit 530 to move along the Z direction to clamp the battery cell against the battery cell support platform 510. After the battery cell is clamped, the controller controls the lifting drive unit 100, the first drive unit 310, and the second drive motor to operate to coat the battery cell with adhesive. Here, the adhesive tape on the battery cell is U-shaped when it arrives, and extends beyond the battery cell support platform 510 and the clamping unit 530 on both sides in the X direction.

[0045] In the embodiments of this application, such as Figure 8As shown, the fourth driving unit 520 is a cylinder, and the pressing unit 530 includes a connecting plate 531, a second sliding plate 532, a second fixing plate 533, a second spring 534, and a pressing plate 535. The telescopic end of the cylinder is connected to one side of the connecting plate 531 to drive the connecting plate 531 to move along the Z direction. The second sliding plate 532 is slidably connected to the other side of the connecting plate 531. The second fixing plate 533 is fixedly connected to the other side of the connecting plate 531 and is located above the second sliding plate 532. The second spring 534 extends along the Z direction and is fixed between the second sliding plate 532 and the second fixing plate 533. The pressing plate 535 is perpendicular to the second sliding plate 532 and can press the battery cell against the battery cell support platform 510. This arrangement allows the second spring 534 to provide a flexible buffer pressing effect, preventing the pressing plate 535 from directly and rigidly contacting and damaging the battery cell.

[0046] Furthermore, in the embodiments of this application, such as Figure 8 As shown, the clamping part 530 also includes a third fixing plate 536 and a slide rail 537. The third fixing plate 536 is fixedly connected to the other side of the connecting plate 531, and the third fixing plate 536 and the second fixing plate 533 are located below and above the connecting plate 531, respectively. The slide rail 537 is fixedly connected to the other side of the connecting plate 531 and is located between the second fixing plate 533 and the third fixing plate 536. The second sliding plate 532 is slidably connected to the slide rail 537 via a slider. A limiting step 5321 is provided below the second sliding plate 532, and the limiting step 5321 abuts against the third fixing plate 536. This configuration allows the limiting step 5321 and the third fixing plate 536 to effectively support the second sliding plate 532, limiting its maximum downward movement and preventing further downward movement that could damage the battery cell.

[0047] The encapsulation process of this application will be described in detail below: Step 1: The battery cell is loaded from the battery cell loading position and moves with the turntable 600 to the battery cell adhesive tape detection position. The controller controls the fourth drive unit 520 to drive the clamping unit 530 to move along the Z direction to clamp the battery cell with the battery cell support platform 510. After the battery cell is clamped, the CCD camera detects the product information of the battery cell located at the battery cell adhesive tape detection position (the product information includes the size and angle data of the battery cell) and sends the detected product information to the controller. Subsequently, the controller controls the lifting drive unit 100, the first drive unit 310 and the second drive motor to operate according to the product information.

[0048] Step 2: After the CCD camera finishes detection, the battery cell moves to the battery cell encapsulation position along with the turntable 600. The controller controls the fourth driving part 520 to drive the pressing part 530 to move along the Z direction to press the battery cell against the battery cell bearing table 510. After the battery cell is pressed, the controller controls the lifting driving part 100, the first driving part 310 and the second driving motor to operate to encapsulate the battery cell.

[0049] Specifically, when the battery cell comes in, the adhesive tape on the battery cell is in a "U" shape. At the beginning, the controller controls the lifting driving part 100 to drive the lifting slide table 200 to slide along the Z direction, thereby driving the two linear driving mechanisms 300 and the two glue scraping mechanisms 400 to slide along the Z direction. First, the two glue scraping mechanisms 400 reach the initial position (the surface of the adhesive tape). After that, the controller controls the first driving part 310 of the two linear driving mechanisms 300 to drive the first slide table 320 to slide along the X direction, thereby driving the two glue scraping mechanisms �00 to slide along the X direction (the positive and negative directions of X respectively) to smooth the "U"-shaped adhesive tape into a "-" shape. During this process, in order to ensure the accuracy of encapsulation, the controller can also control the second driving part 810 to drive the glue scraping mechanism 400 to rotate to further smooth the adhesive tape into a "-" shape.

[0050] Finally, the controller controls the lifting driving part 100 to drive the lifting slide table 200 to continue sliding along the Z direction, thereby driving the two glue scraping mechanisms 400 to scrape the "-" shape flat to both sides to form a "冂" shape, so as to attach the adhesive tape to the two sides of the battery cell that are opposite to each other in the X direction.

[0051] Step 3: After the battery cell encapsulation is completed, the battery cell moves to the battery cell discharging position along with the turntable 600 and enters the next process.

[0052] As described above, the battery cell encapsulation device of the present application controls the driving of the lifting driving part 100 and the first driving part 310 through the controller to automatically control the encapsulation. Compared with the prior art, this automatic control not only improves the production efficiency, reduces the manual intervention, but also greatly improves the consistency and reliability of the product. In the embodiment of the present application, preferably, the lifting driving part 100, the first driving part 310, the second driving part 810 and the third driving motor are all servo motors, and the servo motors achieve precise speed, position and torque control through a closed-loop control system.
