Description

Technical Field

[0001] This utility model belongs to the technical field of stacking equipment, and specifically relates to a stacking machine. Background Technology

[0002] Lithium-ion battery stacking refers to the process of stacking materials such as positive electrode, negative electrode, and separator in a specific order to form a battery assembly. During the stacking process, the positive electrode, negative electrode, and separator need to be tightly bonded to ensure smooth current flow within the battery. This is a crucial step in lithium-ion battery manufacturing, significantly impacting battery performance and quality. Existing stacking devices typically apply appropriate pressure through a pressing mechanism to compress the separator and electrodes on the stacking table, thereby ensuring a tight bond between the positive electrode, negative electrode, and separator. This reduces internal voids and air bubbles, improving battery performance and stability.

[0003] In traditional die-pressing mechanisms, the forward, backward, and upward movement of the die-pressing mechanism is driven by a servo motor via a synchronous pulley or coupling, which then converts the circular motion into linear motion via a lead screw or belt. However, this method introduces friction and geometric errors during the rotational connection of various parts. These errors become significant, especially after improper tension adjustment, installation, or wear. Accumulated over time, these factors affect the accuracy of rotation, consequently impacting the stacking precision and speed of the electrode sheets. Therefore, the efficiency and stability of single-sheet stacking in current battery cell production need improvement. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0035] 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 to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] In the following embodiments and accompanying drawings, reference is made to... Figure 1 The coordinate system is defined with the arrow pointing to the right on the X-axis, the arrow pointing to the front on the Y-axis, and the arrow pointing to the top on the Z-axis.

[0037] Example 1:

[0038] like Figures 1 to 3As shown, this embodiment provides a stacking machine 10, including a stacking table 100, a pressing mechanism 400, and a pressing mechanism for advancing and retreating 500. The pressing mechanism 400 includes a pressing assembly 410 for flexibly pressing down diaphragms and electrodes on the stacking table 100. The pressing mechanism for advancing and retreating 500 includes an advancing and retreating assembly 510, which includes a lifting linear motor 511, a lifting position detection element, an advancing and retreating linear motor 513, and an advancing and retreating position detection element 514. The lifting linear motor 511 and the lifting position detection element are connected to the stacking table 100. The output end of the lifting linear motor 511 is connected to the advancing and retreating linear motor 513 and the advancing and retreating position detection element 514, and the output end of the advancing and retreating linear motor 513 is connected to the pressing assembly 410.

[0039] Specifically, the stacking table 100 is used for stacking wafers to form battery cells. A pressing knife advance / retreat lifting mechanism 500 is located outside the stacking table 100. The output end of the lifting linear motor 511 is connected to a connecting plate 512. An advance / retreat linear motor 513 and an advance / retreat magnetic scale 514 are mounted on the connecting plate 512. The output end of the advance / retreat linear motor 513 is connected to a mounting base 515. The pressing knife assembly 410 is mounted on the mounting base 515. The lifting linear motor 511 drives the connecting plate 512 to rise or fall; the advance / retreat linear motor 513 drives the mounting base 515 to move left or right, thereby enabling the pressing knife advance / retreat lifting mechanism 500 to drive the pressing knife assembly 410 to advance, retreat, and rise. The lifting and lowering position detection components 514 and the forward and backward position detection components 514 are installed at designated positions to remain stationary relative to the stator of the corresponding linear motor, in order to measure the displacement of the moving part. Their installation positions are subject to actual conditions and are not limited here. The lifting and lowering position detection components 514 can be, but are not limited to, magnetic scales, as long as they can be combined with the linear motor to achieve high-precision displacement control. Furthermore, when the magnetic scale is combined with the lifting linear motor 511 and the forward and backward linear motor 513, the magnetic scale has an extremely fast response speed, enabling high-precision, high-speed linear motion control. The pressing component 410 of the pressing mechanism 400 is used to flexibly press against the diaphragm and electrode, and its displacement changes when driven by the forward and backward lifting component 510.

[0040] It is worth noting that during the stacking of diaphragms and electrodes on the stacking table 100, when it is necessary to press the diaphragms or electrodes on the stacking table 100, the pressing knife assembly 410 is driven laterally towards the stacking table 100 by the forward and backward linear motor 513, and then driven longitudinally towards the stacking table 100 by the lifting linear motor 511. Finally, the pressing knife assembly 410 presses the diaphragms or electrodes on the stacking table. During the process of the pressing knife forward and backward lifting mechanism 500 driving the pressing knife assembly 410 towards the stacking table 100, the driving is achieved by a linear motor combined with a position detection device. Because the linear motor has the characteristic of high-speed movement, and the position detection device 220 can detect displacement changes, the two work together to achieve high-speed automated control, thereby improving the efficiency of tablet pressing and effectively increasing the efficiency of single-sheet stacking. Furthermore, the non-contact cooperation between the position detection device and the linear motor avoids wear caused by prolonged contact between components, thus having the advantage of long service life, further ensuring the operational stability of the stacking machine 10.

[0041] Among them, the lifting linear motor 511 and the forward and backward linear motor 513 include a magnetic track stator and a coil mover, with the coil mover slidably mounted on the magnetic track stator.

[0042] Its working principle is as follows: after the magnetic track stator is energized, a magnetic field is generated between the magnetic track stator and the coil mover, thereby generating electromagnetic thrust, which in turn realizes the linear motion of the moving parts. That is, during the operation of the linear motor, the coil mover slides on the magnetic track stator.

[0043] Specifically, in the lifting linear motor 511: the coil mover is connected to the outside of the stacking table 100, and the magnetic track stator is installed on the side of the connecting plate 512 near the stacking table 100. In the forward and backward linear motor 513: the magnetic track stator is installed on the side of the connecting plate 512 away from the stacking table 100, and the coil mover is installed on the mounting base 515. It is understood that the positions of the magnetic track stator and the coil mover can be interchanged; their specific arrangement is not limited here, only requiring that they can correspondingly drive the pressing knife assembly 410 to move forward, backward, and lift.

[0044] Example 2

[0045] This embodiment is a further implementation of Embodiment 1, such as... Figures 1 to 3 As shown, in this embodiment, there are two forward and backward lifting components 510, and in each forward and backward lifting component 510, there are two forward and backward linear motors 513, and the output end of each forward and backward linear motor 513 is connected to a pressure knife component 410.

[0046] Specifically, two connecting plates 512 are set on the front and rear sides of the stacking table 100. Lifting linear motors 511 are installed on the left and right sides of the connecting plates 512 respectively. Pressing knife assemblies 410 are installed on the upper ends of the four mounting seats 515 respectively. Thus, the diaphragm or electrode sheet can be flattened by the four pressing knife assemblies 410, which facilitates the formation of a battery cell with a tightly fitted internal structure.

[0047] To facilitate increasing the stability of the machine's operation, such as Figure 1 and Figure 2 As shown, in some embodiments, the output end of the lifting linear motor 511 is connected to a connecting plate 512, and the connecting plate 512 is provided with a guide rail 516 and a guide rail clamp 517. The pressure knife assembly 410 is slidably disposed on the guide rail 516, and the guide rail clamp 517 is connected to the guide rail 516.

[0048] Specifically, the mounting base 515 is configured as a side-mounted U-shaped structure, and the connecting plate 512 is provided with guide rails 516. The number of guide rails 516 is optional, but not limited to, three. The mounting base 515 is provided with sliding blocks that cooperate with the guide rails 516. By providing sliding blocks on three sides of the mounting base 515, the operation of the mounting base 515 is made more stable. Furthermore, by providing guide rail clamps 517, stable clamping and braking functions can be achieved on the guide rails 516. The method by which the guide rail clamps 517 achieve stable clamping and braking functions is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0049] To facilitate the use of the pressure knife assembly 410, such as Figure 1 and Figure 3 As shown, in some embodiments, the pressing knife assembly 410 includes a diaphragm pressing knife 412 and a control driver 411, with the output of the control driver 411 connected to the diaphragm pressing knife 412.

[0050] Specifically, the control driver 411 may be, but is not limited to, a pressure control cylinder. The pressure control cylinder is connected to the mounting base 515 and is used to drive the diaphragm pressing knife 412 to press down the diaphragm. The way in which the pressure control cylinder drives the diaphragm pressing knife 412 is known to those skilled in the art and is feasible, and will not be described in detail in this embodiment.

[0051] To facilitate the downward pressure of the electrode tabs, such as Figure 1 and Figure 3 As shown, in some embodiments, the pressing mechanism 400 further includes a base 413, a slide rail, a slider 414, and an electrode pressure plate 415. The control driver 411 and the slide rail are disposed on the base 413. The output end of the control driver 411 is connected to the slider 414. The diaphragm pressing knife 412 and the electrode pressure plate 415 are disposed on the slider 414.

[0052] Specifically, the base 413 is mounted on the upper end of the mounting base 515, the control driver 411 is located on one side of the base 413, the slide rail is located on the other side of the base 413, the slider 414 slides on the slide rail, the tab pressure plate 415 and the diaphragm pressure knife 412 are mounted on the slider 414, and the tab pressure plate 415 is positioned close to the center line on the Y-axis of the stacking table 100, that is, the tab pressure plate 415 is positioned close to the tab. In this way, while pressing the diaphragm, the tab can be pressed down simultaneously to prevent wrinkling of the tab. The specific position of the tab pressure plate 415 depends on the actual production situation and is not limited here, as long as it can press down the tab when pressing down the diaphragm.

[0053] Example 3

[0054] This embodiment is a further implementation of embodiment 1 or 2, such as... Figure 1 and Figure 4 As shown, where, Figure 4 The diagram showing a partial break at the serrated edge on the left side of the cell lifting base 210 is only for illustrating the installation of the cell lifting linear motor 230 and does not represent the original complete structure. The original structure on the left side is the same as the structure on the right side. In this embodiment, the stacking machine 10 also includes a cell lifting module 200, which includes a cell lifting base 210, a cell lifting position detection component 220, a cell lifting linear motor 230, and a cell lifting mounting plate 240. The cell lifting linear motor 230 is mounted on the cell lifting base 210, and its output end is connected to the cell lifting mounting plate 240. The stacking stage 100 and the cell lifting position detection component 220 are respectively connected to the cell lifting mounting plate 240.

[0055] Specifically, the cell lifting module 200 is mainly used for lowering the cells during electrode stacking and for lifting and retrieving the cells after stacking is completed. The cell lifting base 210 is installed below the stacking table 100 and connected to the coil mover of the lifting linear motor 511. The coil mover of the cell lifting linear motor 230 is installed on the cell lifting base 210. The magnetic track stator of the cell lifting linear motor 230 and the cell lifting position detection component 220 are installed on the cell lifting mounting plate 240, thereby driving the cell lifting mounting plate 240 to rise and fall. The cell lifting mounting plate 240 is set as an inverted concave plate and provides support for the stacking table 100. The position detection component can be, but is not limited to, a magnetic scale. The way the linear motor and the magnetic scale work together is known to those skilled in the art and is achievable, and will not be described in detail here.

[0056] To facilitate the removal of the battery cells, such as Figure 1 , Figure 4 and Figure 5As shown, in some embodiments, the stacking machine 10 further includes a filling mechanism 300. The stacking table 100 has a groove. The filling mechanism 300 includes a filling lifting driver 310 and a filling strip 320 that cooperates with the groove. The filling lifting driver 310 is disposed on the cell lifting mounting plate 240. The output end of the filling lifting driver 310 is connected to the filling strip 320.

[0057] Specifically, the stacking stage 100 can be, but is not limited to, an E-shaped stacking stage, and the recessed part of the E-shaped stacking stage is a groove. A alignment lifting driver 310 is mounted on the cell lifting mounting plate 240. The shape of the alignment strip 320 matches the shape of the groove. The number of alignment strips 320 can be, but is not limited to, six. The alignment lifting driver 310 can be, but is not limited to, a cylinder. During stacking, the alignment lifting cylinder 310 drives the alignment strips 320 upwards, thereby filling the groove and ensuring normal stacking.

[0058] To ensure the smooth operation of the machine, such as Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the filling mechanism 300 further includes a guide frame and a filling base plate 330. The guide frame has a guide groove that cooperates with the filling strip 320. The filling strip 320 is disposed on the filling base plate 330. The output end of the filling lifting drive 310 is connected to the filling base plate 330. The filling base plate 330 is slidably disposed in the guide frame so that the filling strip 320 is slidably connected to the side wall of the guide groove.

[0059] Specifically, a guide frame is mounted on the cell lifting mounting plate 240. The upper end of the guide frame has a guide groove for accommodating the alignment strip 320, the shape of which matches the shape of the alignment strip 320. In use, the alignment base plate 330 is driven to slide on the guide frame by the alignment lifting cylinder 310, thereby causing the alignment strip 320 to slide on the guide groove until it reaches the groove, thus aligning the stacking platform 100. The cell lifting mounting plate 240 and the stacking platform 100 are provided with guide structures to limit the movement direction of the alignment base plate 330, and the alignment base plate 330 has a sliding groove that cooperates with the guide structure. It is understood that the guide structure may include a linear bearing 340 and a guide shaft 350, and the way the linear bearing 340 and the guide shaft 350 cooperate to limit the movement of the alignment base plate 330 is known to those skilled in the art and is achievable; therefore, it will not be described in detail in this embodiment.

[0060] To facilitate adsorption of the membrane, such as Figure 1 and Figure 6As shown, in some embodiments, the stacking machine 10 further includes a diaphragm smoothing mechanism 600. The diaphragm smoothing mechanism 600 includes a support base 630, a translation driver 610, and a reverse diaphragm suction plate 620 for smoothing the first layer of diaphragm. The support base 630 is disposed on one side of the stacking table 100, and the translation driver 610 is disposed on the support base 630. The output end of the translation driver 610 is connected to the reverse diaphragm suction plate 620.

[0061] Specifically, the diaphragm smoothing mechanism 600 is installed on the rear side of the cell support mechanism. The support base 630 is equipped with a slide rail and a translation driver 610. The reverse diaphragm suction plate 620 is slidably mounted on the slide rail via a slider, allowing it to slide back and forth along the Y-axis. The translation driver 610 can be, but is not limited to, a cylinder. When operation is required, the translation driver 610 drives the reverse diaphragm suction plate 620 to the corresponding position, causing it to vacuum-adsorb the first-layer diaphragm, thereby assisting in smoothing the diaphragm through adsorption. The method of using a cylinder to drive the reverse diaphragm suction plate 620 and the method of the reverse diaphragm suction plate 620 to assist in smoothing the first-layer diaphragm are known to those skilled in the art and are achievable, and will not be described in detail here.

[0062] Thus, as Figure 1 As shown, the overall equipment consists of: a aligning mechanism 300 installed below the stacking table 100 for aligning the stacking table 100; a diaphragm smoothing mechanism 600 installed on the rear side of the cell lifting module 200 for assisting in smoothing the first layer of diaphragm; a pressure knife mechanism 400 installed at the four corners of the cell lifting module 200 for positioning the diaphragm and fixing the electrode in the diaphragm; a pressure knife forward and backward lifting mechanism 500 installed below the pressure knife mechanism 400 and on both sides of the cell lifting module 200 for performing the planar movement of the pressure knife mechanism 400; and a cell lifting module 200 installed directly below the aligning mechanism 300, mainly used for lowering the electrode during the stacking process and lifting and picking up the cell when the stacking is completed.

[0063] The working principle is as follows: During the production process of the battery cell, reference... Figure 5 and Figure 6In the alignment mechanism 300, the alignment strip 320 is lifted to be flush with the E-type plate by the alignment lifting driver 310. The edge of the first-layer diaphragm is pushed by the translation driver 610 of the diaphragm smoothing mechanism 600 to the edge of the E-type plate in the alignment mechanism 300. The diaphragm moves forward and smooths itself on the E-type plate. Subsequently, the pressing mechanism 400 moves forward and backward through the pressing mechanism 500, with the torque mode selected in the electrical control, to accurately and reliably press the diaphragm and electrode. In this way, by introducing the positioning and position feedback system of the pressing mechanism 500 and the cell lifting module 200, and with the torque control mode in the program, the stability, controllability and speed of diaphragm positioning and electrode fixing in the stacking process are steadily improved, and the quality of the cell is also improved in the stacking process.
