Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and more specifically, to a battery stacking device. Background Technology

[0002] Some battery products are formed by stacking multiple individual battery cells. Therefore, in the manufacturing process, multiple batteries need to be stacked together to form a battery pack.

[0003] Multiple battery cells in a battery pack are typically bonded together with adhesive. The industry commonly uses pressure-sensitive adhesives, which require a certain period of pressure holding to activate the bond between cells. Existing battery stacking equipment usually requires manual assistance, resulting in low automation. Furthermore, battery stacking and pressure holding are often performed on different equipment, incurring transfer time and impacting production efficiency. In addition, to prevent damage to the battery tabs during stacking and pressure holding, the battery tabs must be kept on the side. After stacking and pressure holding are completed, the battery pack usually needs to be rotated at a certain angle so that the tabs face upwards to facilitate subsequent processing and testing. Utility Model Content

[0004] In view of this, the present invention provides a battery stacking device with a high degree of automation, high production efficiency, and pressure holding and flipping functions to solve the problems existing in the background art.

[0005] This utility model is achieved through the following technical solution.

[0006] A battery stacking device includes: a feeding mechanism including a robotic arm for handling batteries; a stacking and handling mechanism including a handling module, a receiving module, and a stacking assembly, wherein the stacking assembly includes a placement plate, a connecting frame, and a plurality of hoppers, the connecting frame being connected to the output end of the handling module, each hopper including two spaced-apart discharge plates, each discharge plate being connected to a lifting drive, the lifting drive being mounted on the connecting frame, the placement plate being located between the two discharge plates of the hopper, the output end of the receiving module being connected to a receiving platform, and the placement plate having an opening for the output end of the receiving module to pass through; a pressure holding mechanism including a pressure holding drive and a pressure plate connected to the pressure holding drive; and a flipping mechanism including a flipping drive and a clamping assembly connected to the output end of the flipping drive, the clamping assembly including spaced-apart clamping plates and a support plate, the clamping plates being connected to the clamping drive.

[0007] In the above scheme, the receiving platform is located above the placement plate. The receiving module can drive the receiving platform to move up and down. In specific implementation, the robot transports the batteries to the hopper. At this time, the receiving platform is located in the hopper. The robot places the batteries on the receiving platform one by one. Under the control of the receiving module, the receiving platform lowers by the thickness of one battery after each battery is received. After stacking a battery pack, the lifting drive drives the two placement plates to rise, lifting the stacked batteries. Then, the transport module drives the connecting frame to move, moving the hopper and the stacked batteries to the pressure holding mechanism. Subsequently, the lifting drive resets, causing the two placement plates to fall. The battery pack is placed on the placement plate, and then the pressure plate, driven by the pressure holding drive, holds the pressure on the battery pack, activating the adhesive between the batteries and bonding the stacked batteries together to form a battery pack. After bonding, the lifting drive lifts the hopper and battery pack again. Driven by the transport module, the battery pack moves to the flipping mechanism. Then, the lifting drive drives the unloading plate to descend and place the battery pack on the support plate. Then, the clamping plate moves towards the support plate under the drive of the clamping drive to clamp the battery pack. Finally, the flipping drive flips the battery pack, waiting for the next process equipment to remove the battery pack.

[0008] The two discharge plates of the hopper are spaced apart to allow room for the placement plate and clamping plate, avoiding interference. After the discharge plate descends, the battery can automatically fall onto the placement plate or the support plate for pressure holding or flipping. In addition, multiple hoppers can be set up. While batteries are stacked in one hopper, the other hopper can simultaneously perform pressure holding. At the same time, when the hopper with stacked batteries is sent to the pressure holding station, the batteries that have completed pressure holding can be sent to the flipping mechanism for flipping, thereby effectively improving work efficiency.

[0009] In one example of this utility model, the bottom of the feeding plate is provided with a feeding part that protrudes in the horizontal direction.

[0010] In the above scheme, the feeding section protrudes towards another feeding plate. The feeding section is used to place the battery so that the hopper can move the battery up and down with it.

[0011] In one example of this utility model, the feeding plate is provided with baffles and push-driven components on both sides, and the baffles are connected to the output end of the push-driven components.

[0012] In the above scheme, the push drive can drive the baffle to move, so that the baffle closes the sides of the two discharge plates to prevent the internal batteries from tipping over.

[0013] In one example of this utility model, slide rails are provided on both sides of the feeding plate, and the baffle is slidably installed on the slide rails.

[0014] In the above scheme, the slide rail is used to guide the movement of the baffle and makes the movement of the baffle smoother.

[0015] In one example of this utility model, the top of the placement plate is provided with a support platform, and the pressure plate is located directly above the support platform.

[0016] In the above scheme, the stacked batteries move with the hopper and are placed on the support platform. The pressure plate is located above the support platform, and the batteries are kept under pressure by the pressure plate and the support platform.

[0017] In one example of this invention, the stacking assembly further includes a guide rail, on which the connecting bracket is slidably mounted.

[0018] In the above scheme, the guide rail is used to guide the movement of the connecting frame, and the connecting frame is driven to slide along the guide rail by the transport module.

[0019] In one example of this utility model, a material handling component is installed on the output end of the robot arm. The material handling component includes a suction nozzle, a fixed block, and a clamping drive. The output end of the clamping drive is connected to a movable block, and the suction nozzle is located between the fixed block and the movable block.

[0020] In the above solution, the suction nozzle is used to pick up the battery. The movable block can move closer to and away from the fixed block under the drive of the clamping drive to hold the battery. In conjunction with the suction of the nozzle, the stability of the battery during transportation is further improved, preventing it from moving during transportation and affecting the accuracy of subsequent stacking.

[0021] In one example of this utility model, the flipping mechanism further includes a mounting plate on which the flipping drive and clamping assembly are mounted.

[0022] In the above scheme, the mounting plate is used to provide mounting positions for the flip drive and clamping assembly.

[0023] In one example of this utility model, the flipping mechanism further includes a reversing module, the output end of which is connected to the mounting plate.

[0024] In the above scheme, the equipment can be set up with multiple processing lines. Each processing line can be equipped with a stacking and handling mechanism and a pressure holding mechanism to perform stacking and pressure holding work. When multiple processing lines are set up, the reversing module can drive the mounting plate to move so that the clamping components on it can move to different processing lines for receiving and flipping.

[0025] In one example of this utility model, a visual positioning mechanism is also included, which is disposed between the feeding mechanism and the stacking and handling mechanism. The visual positioning mechanism includes a positioning camera for taking pictures of the battery.

[0026] In the above scheme, after the robotic arm picks up the battery, it moves the battery to the positioning camera for taking pictures and positioning to ensure the accuracy of subsequent stacking.

[0027] As can be seen from the above, the beneficial effects of this utility model are as follows: This application, through the setting of a feeding mechanism, a stacking and handling mechanism, a pressure holding mechanism and a flipping mechanism, can realize the stacking, pressure holding and flipping of batteries, thereby integrating the stacking, pressure holding and flipping of batteries into the same equipment, greatly saving transfer time, and with a high degree of automation, requiring no manual assistance, which can effectively improve production efficiency; This application utilizes the combination of a feeding plate, a lifting drive component, and a placement plate. The lifting drive component alone is sufficient to handle the loading and unloading of batteries within the hopper, resulting in a simplified structure and effectively reducing equipment complexity. The stacking and handling mechanism of this application is equipped with multiple hoppers, which can enable stacking, pressure holding and flipping operations to be carried out simultaneously, significantly improving production efficiency.

Detailed Implementation

[0038] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Please refer to Figures 1 to 8 In a preferred embodiment of this application, a battery stacking device is provided, which includes a feeding mechanism 1, a stacking and transporting mechanism 3, a pressure holding mechanism 4, and a flipping mechanism 5. The feeding mechanism 1 includes a robotic arm 11 for handling batteries; the stacking and handling mechanism 3 includes a handling module 31, a receiving module 32, and a stacking assembly. The stacking assembly includes a placement plate 33, a connecting frame 34, and several hoppers. The connecting frame 34 is connected to the output end of the handling module 31. The hopper includes two spaced-apart discharge plates 351. Both discharge plates 351 are connected to a lifting drive. The lifting drive is mounted on the connecting frame 34. The placement plate 33 is located between the two discharge plates 351 of the hopper. The output end of the receiving module 32 is connected to a receiving platform. The placement plate 33 has an opening for the output end of the receiving module 32 to pass through. The pressure holding mechanism 4 includes a pressure holding drive 42 and a pressure plate 43 connected to the pressure holding drive 42. The flipping mechanism 5 includes a flipping drive 51 and a clamping assembly 52 connected to the output end of the flipping drive 51. The clamping assembly 52 includes spaced-apart clamping plates 521 and a bearing plate 522. The clamping plates 521 are connected to the clamping drive 523.

[0040] It should be noted that, as Figure 1As shown, the battery stacking equipment in this embodiment includes two processing lines, which can simultaneously perform stacking, pressure holding and flipping of two sets of batteries. Each processing line has a stacking component including two hoppers. For ease of explanation, the two hoppers are named the first hopper 35a and the second hopper 35b according to the direction of battery movement. At the same time, the lifting drive connected to the feeding plate 351 of the first hopper 35a and the second hopper 35b are named the first lifting drive 353a and the second lifting drive 353b, respectively.

[0041] Specifically, the receiving platform is located above the placement plate 33. The output end of the receiving module 32 passes through the placement plate 33, thereby driving the receiving platform to move up and down. In the initial state, the receiving platform is located between the two discharge plates 351 of the first hopper 35a. The robot arm 11 transports the battery to the first hopper 35a and places the battery on the receiving platform. Under the control of the receiving module 32, the receiving platform lowers by the thickness of one battery for each battery received. After stacking a battery pack, the first lifting drive 353a drives the first hopper 35a to rise, lifting the stacked battery pack. Then, the transport module 31 drives the connecting frame 34 to move, moving the first hopper 35a and the battery pack to the pressure holding mechanism 4. Then, the first lifting drive 353a resets, causing the two discharge plates 351 to fall, and the battery pack is placed on the platform. The battery pack is placed on the placement plate 33. Then, the pressure plate 43 moves under the drive of the pressure holding drive 42, applying pressure to the battery pack in the first hopper 35a, activating the adhesive on the surface of the battery, so that multiple batteries are bonded together to form a complete battery pack. After bonding, the first lifting drive 353a lifts the first hopper 35a again. Under the drive of the transport module 31, the first hopper 35a and the battery pack move to the flipping mechanism 5. The first lifting drive 353a drives the first hopper 35a to descend, so that the battery pack is placed on the support plate 522. Then, the clamping plate 521 moves towards the support plate 522 under the drive of the clamping drive 523 to clamp the battery pack. Under the drive of the flipping drive 51, the battery pack is flipped and waits for the next process equipment to remove the battery pack. Thus, the processing of one battery pack is completed.

[0042] Understandably, the surface of the battery is pre-coated with an adhesive that can be activated by pressure. By applying pressure for a certain period of time through the pressure plate 43, the adhesive on the surface of the battery can be activated, causing the batteries to stick together to form a battery pack.

[0043] It should be noted that since there are two material hoppers, when batteries are stacked in the first material hopper 35a, the second material hopper 35b is located at the pressure holding mechanism 4 and performs pressure holding work simultaneously. Correspondingly, when the first material hopper 35a moves to the pressure holding mechanism 4 for pressure holding, the second material hopper 35b moves to the flipping mechanism 5 and performs battery pack flipping work simultaneously. By setting up multiple material hoppers, multiple processes can be carried out simultaneously, thereby effectively improving production efficiency.

[0044] The feeding plate 351 is spaced out to make way for the placement plate 33 and the clamping plate 521, avoiding interference during movement. After the feeding plate 351 descends, the battery can be automatically placed on the placement plate 33 or the support plate 522 for pressure holding or flipping.

[0045] Preferably, the conveying module 31 and the receiving module 32 are made of linear motors or linear modules, which are common in the prior art. The specific structure will not be described in detail here.

[0046] Preferably, the lifting drive component is a cylinder.

[0047] Please refer to Figures 3 to 6 The bottom of the feeding plate 351 is provided with a feeding part 3511 protruding in the horizontal direction. The feeding part 3511 protrudes towards another feeding plate 351 and is used to place the battery so that the hopper can drive the battery to rise and fall together with it.

[0048] Please refer to Figures 3 to 6 The feeding plate 351 is provided with baffles 352 and push drive 354 on both sides. The baffles 352 are connected to the output end of the push drive 354. The push drive 354 can drive the baffles 352 to move, so that the baffles 352 seal the sides of the material bins of the two feeding plates 351, preventing the internal batteries from tipping over during movement or pressure holding.

[0049] Furthermore, slide rails 355 are provided on both sides of the feeding plate 351, and baffles 352 are slidably installed on the slide rails 355. The slide rails 355 are used to guide the movement of the baffles 352 and make the movement of the baffles 352 smoother.

[0050] Please refer to Figures 3 to 6 The top of the placement plate 33 is provided with a support platform 331, and the pressure plate 43 is located directly above the support platform 331. After the hopper moves to the pressure holding mechanism 4, the stacked batteries are placed on the support platform 331, and the pressure plate 43 is located above the support platform 331. The pressure plate 43 and the support platform 331 are used to hold the batteries under pressure.

[0051] Please refer to Figure 3 and Figure 5 The stacking assembly also includes a guide rail 36, and a connecting frame 34 is slidably mounted on the guide rail 36. The guide rail 36 is used to guide the movement of the connecting frame 34, which slides along the guide rail 36 under the drive of the transport module 31.

[0052] Please refer to Figure 2The output end of the robotic arm 11 is equipped with a material handling component 12, which includes a suction nozzle 121, a fixed block 122 and a clamping drive 123. The output end of the clamping drive 123 is connected to a movable block 124, and the suction nozzle 121 is located between the fixed block 122 and the movable block 124.

[0053] The suction nozzle 121 is used to pick up the battery. The movable block 124 can move closer to and further away from the fixed block 122 under the drive of the clamping drive 123, thereby clamping the battery. In conjunction with the suction of the suction nozzle 121, the stability of the battery during transportation is further improved, preventing the battery from slipping during transportation and affecting the accuracy of subsequent stacking.

[0054] Specifically, when gripping the battery, the robotic arm 11 moves the material handling component 12 to the battery, placing the battery between the movable block 124 and the fixed block 122. Then, the movable block 124 moves toward the fixed block 122 under the drive of the gripping drive component 123 to clamp the battery. Subsequently, the suction nozzle 121 is activated to hold the battery. The stability of the battery can be effectively ensured through the movable block 124 and the suction nozzle 121.

[0055] Preferably, the suction nozzle 121 is a vacuum suction nozzle.

[0056] Please refer to Figure 1 A visual positioning mechanism 2 is provided between the feeding mechanism 1 and the stacking and handling mechanism 3. The visual positioning mechanism 2 includes a positioning camera 21 for taking pictures of the battery.

[0057] Specifically, after the robotic arm 11 picks up the battery, it moves it to the positioning camera 21 to take a picture and locate it, so as to ensure the accuracy of subsequent stacking.

[0058] Please refer to Figure 7 The pressure holding mechanism 4 includes a bracket 41, and a pressure holding drive 42 is mounted on the bracket 41. The output end of the pressure holding drive 42 is also connected to a buffer plate 44. The buffer plate 44 is connected to the pressure plate 43 through a guide post. A spring 45 is sleeved on the guide post. The spring 45 can play a certain buffering role when the pressure plate 43 applies pressure to the battery, so as to avoid excessive pressure that could damage the battery.

[0059] Preferably, two pressure plates 43 are provided to perform pressure holding work on the batteries on the two processing lines respectively.

[0060] Please refer to Figure 8 The flipping mechanism 5 also includes a mounting plate on which the flipping drive 51 and the clamping assembly 52 are mounted. The mounting plate is used to provide mounting positions for the flipping drive 51 and the clamping assembly 52.

[0061] Preferably, there are two flipping drive units 51 and two clamping components 52, which are used to flip the battery packs sent from the two processing lines respectively.

[0062] Furthermore, the flipping mechanism 5 also includes a reversing module 53, the output end of which is connected to the mounting plate.

[0063] Since this equipment is equipped with two processing lines, the reversing module 53 can drive the mounting plate to move back and forth between the two processing lines, so that the two clamping components 52 on the mounting plate can receive the battery packs that have completed pressure holding on the two processing lines respectively.

[0064] Preferably, the commutation module 53 is a linear motor or a linear module.

[0065] Preferably, the clamping drive component 523 is a cylinder.

[0066] Please refer to Figures 1 to 8 The following explains the specific operation and working principle of this battery stacking equipment: First, the robotic arm 11 grasps the battery and moves it above the positioning camera 21 for photographing and positioning. Then, it places the battery onto the receiving platform in the first hopper 35a. Each time a battery is placed, the receiving platform descends by the thickness of one battery. After a stack of batteries is completed, the baffles 352 on both sides of the first hopper 35a move, sealing both sides of the first hopper 35a. Then, the first lifting drive 353a lifts the first hopper 35a, and the transport module 31 starts, moving the first hopper 35a to the pressure holding mechanism 4. After it is in place, the first lifting drive 353a resets, and the batteries in the first hopper 35a fall onto the support platform 331. Then, the pressure plate 43 moves. The batteries in the first hopper 35a are pressurized to activate the adhesive on the battery surface. After the pressurization is completed, the baffles 352 on both sides of the first hopper 35a are reset, opening both sides of the first hopper 35a. At the same time, the first lifting drive 353a lifts the first hopper 35a. Then the transport module 31 is activated to move the first hopper 35a to the transport mechanism. The first lifting drive 353a descends and places the battery pack on the support plate 522. Then the clamping plate 521 descends and clamps the battery pack under the drive of the clamping drive 523. The flipping drive 51 is activated to flip the battery pack. Then, the battery pack waits for the next process equipment to transport it away. This completes the processing of one battery pack.

[0067] When the robot arm 11 stacks batteries inside the first hopper 35a, the second hopper 35b is located at the pressure holding mechanism 4. The pressure plate 43 holds the stacked batteries in the second hopper 35b under pressure, so that the pressure holding work is carried out simultaneously while the batteries are stacked. Similarly, when the first hopper 35a moves to the pressure holding mechanism 4 for pressure holding, the second hopper 35b and the battery pack inside it that has completed the pressure holding work move synchronously to the flipping mechanism 5 for flipping.
