Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to an automatic lithium battery stacking device. Background Technology

[0002] In the manufacturing process of lithium batteries, the stacking process is a crucial step. Its main function is to precisely stack the positive electrode, negative electrode, and separator of the lithium battery in a specific order to form the cell structure of the lithium battery. The accuracy and efficiency of stacking directly affect the performance, capacity, and production quality of the lithium battery.

[0003] The "Automatic Lithium Battery Stacking Device" disclosed in patent publication number "CN222546404U" includes: a support base, an inner support plate fixedly connected inside the support base, a stepper motor, an intermittent transmission box, and a reduction gearbox mounted on the upper side wall of the inner support plate, a processing turntable fixedly connected to the output end of the reduction gearbox, a support platform mounted on the upper side wall of the support base, a positive electrode box, a separator unwinding assembly, and a negative electrode box mounted clockwise on the upper side wall of the support platform; a rear support plate fixedly connected to the upper side wall of the support base, a top support plate mounted on the upper side wall of the rear support plate, and three sets of linear motors mounted on the lower side wall of the top support plate. A sliding block is fixedly connected to the output end of each linear motor, and an electric push rod is fixedly connected to the lower side wall of each sliding block. In this invention, automatic stacking can be completed after a single positioning operation, effectively improving the alignment and stacking quality of the electrode sheets.

[0004] The device uses a stepper motor, an intermittent transmission box, and a reduction gearbox. The linear motor can push the vacuum suction cup with the positive and negative electrode sheets adsorbed to the top of the stacking stage for the initial positioning of the positive and negative electrode sheets. However, the device has low position adjustment accuracy, making it difficult to achieve precise positioning when adjusting the position of the stacked components. This can easily lead to misalignment of the positive electrode sheets, negative electrode sheets, and separator during the stacking process, which in turn affects the consistency and performance stability of the battery cells. Furthermore, the stacked materials on the stacking stage are not limited and are prone to displacement due to the rotational inertia of the stacking stage.

[0005] To address these issues, this invention provides an automatic lithium battery stacking device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an automatic lithium battery stacking device, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic lithium battery stacking device, comprising a base, a position adjustment component on the top of the base, and a feeding and stacking component on one side of the base; the position adjustment component includes mounting plates, which are fixedly connected to the top two ends of the base, a lead screw is rotatably connected between the two mounting plates, a nut block is threaded onto the outer wall of the lead screw, an assembly block is fixedly connected to the top of the nut block, an insertion hole is provided on the top of the assembly block, and a photosensitive sensor is fixedly installed inside the assembly block; the feeding and stacking component includes a vertical rod, which is fixedly connected to one side of the base, a combination frame is fixedly connected to the top of the vertical rod, a limit groove is provided on the inner wall of the combination frame; the feeding and stacking component also includes a slider, protrusions are fixedly connected to both sides of the slider, the protrusions are slidably connected to the inside of the limit groove, the outer wall of the slider is slidably connected to the inner wall of the combination frame, a docking plate is fixedly connected to the bottom of the slider, and a light source emitting lamp is fixedly connected to the bottom of the docking plate.

[0008] A limiting slide rod is fixedly connected between the two mounting plates. The limiting slide rod is slidably connected to the inside of the nut block, which guides and limits the movement of the nut block, preventing it from deviating as the lead screw rotates. Two protective plates are also fixedly connected between the two mounting plates, enclosing the lead screw and the limiting slide rod. This effectively prevents dust and impurities from entering the transmission structure, protecting the normal operation of the lead screw and the limiting slide rod. A servo motor is fixedly mounted on one side of the base. The output shaft of the servo motor is fixedly connected to one end of the lead screw, allowing precise control of the lead screw's rotation angle and speed. A roller is fixedly mounted on the bottom of the nut block. The roller makes rolling contact with the top of the base, reducing friction between the nut block and the base, making the nut block move more smoothly.

[0009] The position adjustment component also includes a stacking box, the bottom of which is fixedly connected to a plug rod. The plug rod is inserted into the inside of the plug hole to realize quick assembly and disassembly and precise positioning of the stacking box and the assembly block, which facilitates the subsequent transfer and processing of the stacked cells.

[0010] A vertical cylinder is fixedly installed inside the slider. The vertical cylinder passes through the docking plate, and a vacuum suction cup is fixedly installed at the movable end of the vertical cylinder. The vacuum suction cup can be driven to move up and down by the vertical cylinder, and the suction force of the vacuum suction cup can be used to stably grasp the electrode and the diaphragm. A bracket is fixedly connected to one side of the upright. A horizontal cylinder is fixedly installed on the top of the bracket. The movable end of the horizontal cylinder passes through one side wall of the combined frame and is fixedly connected to one side of the slider. It can drive the slider to move horizontally within the combined frame to realize the transfer of the electrode and the diaphragm.

[0011] A shim block is fixedly connected to the top of the base, and a material box is fixedly connected to the top of the shim block. There are three sets of shim blocks and material boxes evenly distributed along the length of the base. There are also three sets of material stacking components. The position of the upright corresponds one-to-one with the position of each shim block, so that each material box is located directly below the corresponding slider movement trajectory. Each material box contains a positive electrode sheet, a negative electrode sheet, and a separator, which can realize the classified storage and synchronous feeding of positive electrode sheets, negative electrode sheets, and separators, and improve the stacking efficiency.

[0012] There are four photosensitive sensors, which are respectively set at the four corners of the assembly block. There are also four light source emitting lamps fixedly installed at the bottom of each docking plate, which are also respectively set at the four corners of the bottom of the docking plate. The assembly block and the docking plate have the same size and specifications. Through the precise correspondence between the light source emitting lamps at the four corners and the photosensitive sensors, high-precision position calibration of the feeding stacking component and the position adjustment component can be achieved.

[0013] A controller is fixedly installed on one side of the base. The servo motor, photosensitive sensor, horizontal cylinder, vertical cylinder, vacuum suction cup, and light source emitter are all electrically connected to the controller. The controller enables automated control of each component, improving the overall coordination and automation of the device. Beneficial effects

[0014] This invention provides an automatic lithium battery stacking device. Compared with the prior art, it has the following advantages: 1. This automatic lithium battery stacking device features a position adjustment assembly consisting of a servo motor, lead screw, nut block, and limiting slide bar. The servo motor precisely controls the rotation of the lead screw, driving the nut block to move stably along the limiting slide bar, thereby achieving high-precision position adjustment of the assembly blocks and stacking boxes. This effectively solves the problem of low position adjustment accuracy in traditional devices, laying the foundation for subsequent precise stacking. Three sets of feeding and stacking components correspond one-to-one with three sets of material boxes, each containing a positive electrode sheet, a negative electrode sheet, and a separator. A horizontal cylinder drives the slider to move horizontally, while a vertical cylinder drives the vacuum suction cup to move up and down, simultaneously completing the gripping and transfer of the three materials. This significantly improves the coordination between feeding and stacking, increasing stacking efficiency.

[0015] 2. This automatic lithium battery stacking device utilizes photosensitive sensors at the four corners of the assembly block in conjunction with light-emitting lamps at the four corners of the docking plate. The controller, by detecting the light signals received by the photosensitive sensors, can calibrate the relative positions of the feeding stacking components and the position adjustment components in real time. This ensures that the vacuum suction cups can accurately place the electrodes and separators into the stacking box, preventing misalignment and improving stacking accuracy. Two protective plates surround the lead screw and limiting slide rod, effectively preventing dust and impurities from the production environment from entering the transmission structure, reducing wear on the lead screw and limiting slide rod, preventing transmission jamming, and extending the device's service life. Simultaneously, the rollers at the bottom of the nut block reduce friction between it and the base, making the nut block move more smoothly and further ensuring transmission stability.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0020] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1 to 7 This application provides an automatic lithium battery stacking device, including a base 1. The base 1 serves as the basic support component of the device and is made of high-strength metal material to ensure the overall stability of the device. A position adjustment component 2 is provided on the top of the base 1 for precise adjustment of the stacking position; a feeding and stacking component 3 is provided on one side of the base 1 for gripping, transferring and stacking the electrode sheets and separators.

[0022] The position adjustment assembly 2 includes mounting plates 21, which are fixedly connected to the top two ends of the base 1 by bolts. A lead screw 23 is rotatably connected between the two mounting plates 21 via bearings. The lead screw 23 is a high-precision ball screw, characterized by high transmission accuracy and low wear. A nut block 25 is threaded onto the outer wall of the lead screw 23. An assembly block 26 is fixedly connected to the top of the nut block 25 by welding. An insertion hole 29 is provided on the top of the assembly block 26. A photosensitive sensor 210 is fixedly installed inside the assembly block 26 by screws. The photosensitive sensor 210 is a high-sensitivity photoelectric sensor (model Omron EE-SY120, which is compact, fast-response, and suitable for high-precision position calibration scenarios), which can accurately receive light signals and convert them into electrical signals.

[0023] A limiting slide rod 22 is bolted between the two mounting plates 21. The limiting slide rod 22 is slidably connected to the inside of the nut block 25. The limiting slide rod 22 is parallel to the lead screw 23, which prevents the nut block 25 from rotating with the lead screw 23 during movement. A protective plate 212 is bolted between the two mounting plates 21. The protective plate 212 is made of transparent plastic, which facilitates observation of the internal transmission and provides protection. There are two protective plates 212, which enclose the lead screw 23 and the limiting slide rod 22. A servo motor 24 is bolted to one side of the base 1. The servo motor 24 is a servo motor with position feedback function. Its output shaft is fixedly connected to one end of the lead screw 23 through a coupling, which can accurately control the rotation angle and speed of the lead screw 23. A roller 211 is mounted on the bottom of the nut block 25 through a rotating shaft. The roller 211 is made of wear-resistant rubber. The roller 211 makes rolling contact with the top of the base 1, which can reduce the friction when the nut block 25 moves.

[0024] The position adjustment assembly 2 also includes a stacking box 27, which is used to store stacked positive electrode plates, negative electrode plates, and separators. It has an internal positioning structure to ensure that the materials do not shift during the stacking process. A plug rod 28 is welded to the bottom of the stacking box 27. The plug rod 28 matches the size of the insertion hole 29 and is inserted into the interior of the insertion hole 29, enabling quick positioning and installation of the stacking box 27 and the assembly block 26. The stacking box 27 also restricts the stacked materials to prevent them from shifting due to inertia when the nut block 25 moves.

[0025] The feeding and stacking assembly 3 includes a vertical pole 31, which is bolted to one side of the base 1. A combination frame 33 is welded to the top of the vertical pole 31. The inner wall of the combination frame 33 has a limiting groove 35, which is a rectangular groove structure. The feeding and stacking assembly 3 also includes a slider 36. Protrusions 37 are welded to both sides of the slider 36. The size of the protrusions 37 matches the size of the limiting groove 35. The protrusions 37 and the limiting groove 35 are slidably connected internally. The outer wall of the slider 36 is slidably connected to the inner wall of the combination frame 33. The cooperation between the protrusions 37 and the limiting groove 35 ensures that the slider 36 does not deviate when moving horizontally.

[0026] A vertical cylinder 38 is bolted to the inside of the slider 36. The piston rod of the vertical cylinder 38 passes through the docking plate 39. A vacuum suction cup 311 is bolted to the movable end of the vertical cylinder 38. The vacuum suction cup 311 is made of silicone, which has good sealing and adsorption force, and can stably grasp the electrode and diaphragm without damaging their surfaces. A bracket 32 ​​is welded to one side of the upright 31. A horizontal cylinder 34 is bolted to the top of the bracket 32. The piston rod of the horizontal cylinder 34 passes through one side wall of the assembly frame 33 and is bolted to one side of the slider 36, which can drive the slider 36 to move horizontally within the assembly frame 33.

[0027] A shim block 213 is bolted to the top of the base 1. The shim block 213 is used to adjust the height of the material box 214 so that it matches the gripping height of the vacuum suction cup 311. The material box 214 is bolted to the top of the shim block 213. The material box 214 has a partition structure inside, which can neatly store the electrode sheets and separators. There are three sets of shim blocks 213 and material boxes 214 evenly distributed along the length of the base 1. There are also three sets of material stacking components 3. The position of the upright 31 corresponds one-to-one with the position of each shim block 213, so that each material box 214 is located directly below the moving trajectory of the corresponding slider 36. Each material box 214 contains a positive electrode sheet, a negative electrode sheet, and a separator.

[0028] Four photosensitive sensors 210 are respectively located at the four corners of the assembly block 26. Four light source emitting lamps 310 are also fixedly installed at the bottom of each docking plate 39, respectively located at the four bottom corners of the docking plate 39. The assembly block 26 and the docking plate 39 have the same dimensions, ensuring that the four light source emitting lamps 310 correspond one-to-one with the four photosensitive sensors 210. The light source emitting lamps 310 are LED lamps, which have the characteristics of stable light emission and low energy consumption, and their emitted light signals can be accurately received by the photosensitive sensors 210.

[0029] A controller 4 is bolted to one side of the base 1. The controller 4 is an industrial-grade PLC controller (Siemens S7-1214C, featuring high-speed counting capabilities, real-time processing of photosensitive sensor signals, and rapid response; suitable for controlling multiple sets of cylinders and servo motors working in tandem; user-friendly programming software with high stability), possessing powerful data processing and signal control functions. The servo motor 24, photosensitive sensor 210, horizontal cylinder 34, vertical cylinder 38, vacuum suction cup 311, and light source emitting lamp 310 are all electrically connected to the controller 4 via wires. The controller 4 can receive signals from the photosensitive sensor 210 and send control commands to other components, achieving automated operation of the device.

[0030] All electrical devices in this plan are powered by an external power source.

[0031] Working principle: This automatic lithium battery stacking device is based on the controller 4. Through the coordinated operation of the position adjustment component 2 and the feeding and stacking component 3, it realizes the automatic and precise stacking of lithium battery positive electrode sheets, negative electrode sheets and separators. The specific workflow is as follows: The operator first places the positive electrode, negative electrode, and separator into the three sets of material boxes 214 respectively. Then, the device is started by the controller 4, and parameters such as the stacking order and number of stacking layers are set. The controller 4 sends a start signal to the servo motor 24. The output shaft of the servo motor 24 drives the lead screw 23 to rotate precisely between the two mounting plates 21. Since the lead screw 23 is threadedly connected to the nut block 25 and the nut block 25 is slidably engaged with the limit slide bar 22, the rotation of the lead screw 23 is converted into the horizontal movement of the nut block 25 along the limit slide bar 22. The assembly block 26 on the top of the nut block 25 moves synchronously with the nut block 25. At the same time, the photosensitive sensors 210 at the four corners of the assembly block 26 receive the instructions from the controller 4 in real time and are in a state of waiting for detection. When the assembly block 26 moves to the preset initial stacking position, the controller 4 controls the servo motor 24 to stop running according to the position feedback signal of the servo motor 24, and completes the initial positioning of the position adjustment component 2. At this time, the operator inserts the plug 28 at the bottom of the stacking box 27 into the plug hole 29 at the top of the assembly block 26 to achieve precise docking and fixation between the stacking box 27 and the assembly block 26. Then, the controller 4 sends a command to the first set of feeding and stacking components 3. The horizontal cylinder 34 of this component is activated first, pushing the slider 36 to slide within the combination frame 33 until the docking plate 39 at the bottom of the slider 36 moves directly above the material box 214. Subsequently, the controller 4 sends a descent signal to the vertical cylinder 38. The movable end of the vertical cylinder 38 drives the vacuum suction cup 311 to move downward until the vacuum suction cup 311 contacts the surface of the positive electrode in the material box 214. The controller 4 controls the vacuum suction cup 311 to activate the negative pressure adsorption function, and uses adsorption force to stably grasp the positive electrode. After the vacuum suction cup 311 picks up the positive electrode, the vertical cylinder 38 first drives the positive electrode to return to the preset height. Then, the horizontal cylinder 34 moves in the opposite direction, pushing the slider 36 to move the positive electrode to the top of the stacking box 27. During this process, the light source emitting lamps 310 at the four corners of the bottom of the docking plate 39 are activated simultaneously, emitting stable light signals to the photosensitive sensors 210 at the four corners of the assembly block 26. After receiving the light signals, the photosensitive sensors 210 feed the signals back to the controller 4. The controller 4 determines whether the docking plate 39 is precisely aligned with the stacking box 27 by comparing the time difference and intensity of the light signals received by the four photosensitive sensors 210. If there is a slight offset, the controller 4 immediately sends a fine-tuning signal to the servo motor 24. The servo motor 24 drives the lead screw 23 to fine-tune the position of the nut block 25 until all four photosensitive sensors 210 stably receive the light signals, thus completing the position calibration. After the position calibration is completed, the controller 4 controls the vertical cylinder 38 to descend again, and place the positive electrode sheet picked up by the vacuum chuck 311 smoothly into the stacking box 27. Then the vacuum chuck 311 stops the negative pressure adsorption, the vertical cylinder 38 drives the vacuum chuck 311 to reset upward, and the horizontal cylinder 34 drives the slider 36 to return to the initial position, completing the stacking of a single positive electrode sheet. According to the preset stacking order, the controller 4 controls the second group, the third group, and the second group of feeding and stacking components 3 to repeat the above "grab-transfer-calibrate-stack" process, and stacks the separator, negative electrode, and separator on top of the positive electrode in the stacking box 27 to form a complete basic unit. After a set of basic units is stacked, the controller 4 sends a signal to the servo motor 24, which drives the nut block 25 to move the assembly block 26 and the stacking box 27 along the limit slide bar 22 by one unit distance. Then the above process is repeated to realize the cyclic operation of multi-layer stacking.
