Description

Technical Field

[0001] This application relates to the field of lead-acid battery assembly equipment technology, and in particular to a stacking and sorting unit. Background Technology

[0002] Patent document CN119660243A discloses a patting and sorting mechanism for organizing battery plates. In the primary stacking mechanism, rollers remove the plates from the conveyor line and rotate them to their highest point. The patting and sorting mechanism then pushes them upright, and the rollers place the plates back onto the conveyor line. Finally, the plates are stacked in a feeding device and then patted neatly by a patting component. However, during the process of the plates moving from the rollers to the feeding device, they are affected by equipment vibration, which may cause them to become skewed again. As a result, the stacked plate modules are not neat, and the patting component cannot quickly and neatly pat the already stacked plate modules. Utility Model Content

[0003] Therefore, the object of the present invention is to provide a stacking and sorting unit that at least partially solves the problems in the prior art.

[0004] A stacking and sorting unit includes a conveyor line and a stacking device and a sorting device disposed above the conveyor line. The stacking device is configured to stack several battery plates into a plate module, and the sorting device is configured to pat the plate module neatly. The stacking device includes a receiving platform and a first driving assembly. The receiving platform includes a limiting member and a receiving block. The limiting member is disposed on one side of the receiving block opposite to the incoming material direction. The first driving assembly is configured to raise and lower the receiving block in the conveyor line. The sorting device includes a flipping part and a first patting part located above the flipping part. The flipping part includes a flipping component. The first striking part includes a third driving component and a first and second push plates disposed opposite to each other. The first and second push plates are respectively located on both sides of the receiving cavity. The third driving component is configured to drive the first and second push plates to move relatively synchronously closer or relatively synchronously further apart. The second driving component is configured to drive the first and second push plates to rotate around a central axis. The receiving cavity of the flipping part is provided with a carrier plate, and the carrier plate and the flipping part are connected by an elastic element. The first and second push plates are provided with a vibration motor connected to the carrier plate. The first striking part includes a third driving component and a first push plate and a second push plate disposed opposite to each other. The flipping part is flipped upward by 90°. The first push plate and the second push plate are respectively located on both sides of the receiving cavity. The third driving component is configured to drive the first push plate and the second push plate to move relatively synchronously closer or relatively synchronously further apart.

[0005] Thus, battery plates are sequentially stacked on the receiving platform to form electrode modules. The first drive assembly drives the receiving block to descend below the conveyor line, and the electrode modules are automatically transferred onto the conveyor line. The electrode modules then move backward along the conveyor line into the receiving cavity of the flipper. The second drive assembly drives the flipper to rotate upward 90°, placing the electrode modules in an upright position. The third drive assembly drives the first and second push plates to quickly tap and straighten the electrode modules. The second drive assembly then drives the flipper to rotate downward 90°, switching the electrode modules from an upright to a horizontal position, and the electrode modules fall back onto the conveyor line. This application first receives a preset number of battery plates and gradually stacks them into electrode modules during the receiving process. Then, an independent sorting device is used to tap and straighten the electrode modules, achieving rapid plate receiving, stacking, and sorting of battery plates, with a maximum coating speed of 35 meters per minute. The sorting device uses a vibration motor and left and right tapping to sort the electrode plate module. It not only sorts quickly and effectively, but the vibration motor also has the characteristics of high frequency and small amplitude, which will not damage the battery electrode plate.

[0006] In one embodiment of this application, the flipping component includes a base, a first tray, and a second tray. The base is fixedly connected to the central shaft. The fixed ends of the first and second trays are fixedly connected to the base, and their bearing ends extend in the opposite direction, forming the receiving cavity together with the base. The carrier plate is located between the first tray and the second tray. When the opening of the receiving cavity faces the receiving device, the first tray is located in the conveyor line. The electrode module moves with the conveyor line to the top of the first tray. After the electrode module enters the receiving cavity, the flipping component flips upward 90° to switch the electrode module to an upright state. The first and second trays are located on both sides of the electrode module. After the electrode module has been tapped and arranged, the flipping component flips downward 90° to switch the electrode module to a horizontal state. The second tray is located in the conveyor line, and the electrode module moves backward with the conveyor line to leave the receiving cavity to complete the unloading.

[0007] Preferably, the base is a square hollow structure, and a connecting plate is provided on one side of the base corresponding to the carrier plate. The connecting plate has a bent lug that attaches to the outside of the base, and the connecting plate is connected to the base through the lug. The elastic element is disposed between the carrier plate and the connecting plate, and the vibration motor is located inside the base. The connecting plate has a clearance hole corresponding to the vibration motor. By disconnecting the lug from the side plate, the carrier plate and the vibration motor can be removed together, and the carrier plate and vibration motor module design facilitates debugging.

[0008] In one embodiment of this application, the first support frame of the sorting device is provided with a guide rod located above the central axis. The first push plate and the second push plate are mounted on the guide rod through guide bushings. The telescopic rods of the two first cylinders in the third drive assembly are respectively connected to the first push plate and the second push plate. A downwardly extending mounting plate is mounted on the guide bushing, and the first push plate and the second push plate are fixedly connected to the corresponding mounting plate. A push block protruding towards the second push plate is provided on the inner side of the first push plate. The battery electrode plate has tabs. When the electrode plate module is in an upright state, the tabs face the first push plate. During the tapping process, the push block contacts the part below the tabs of the electrode plate module. The push block and the second push plate together complete the tapping and sorting of the electrode plate module.

[0009] In one embodiment of this application, the first drive assembly is disposed below the conveyor line and includes a servo motor, a spur gear, and a cylindrical rack. A support member is disposed below the receiving block. The top end of the cylindrical rack is fixedly connected to the support member, and its side is meshed with the spur gear. The output shaft of the servo motor is connected to the spur gear. Preferably, a second support frame is disposed below the conveyor line. A guide rod is disposed between the upper and lower plates of the second support frame, and the support member is fixedly connected to a bushing on the guide rod. The servo motor is located below the lower plate, and the cylindrical rack passes through the lower plate and meshes with the spur gear. The first drive assembly, as the lifting power source for the receiving block, adopts a combination structure of spur gear and cylindrical rack, ensuring the repeatability and stability of the receiving block's lifting, improving the quality of the battery electrode plate stacking, and preventing damage to the battery electrode plates in this process.

[0010] In one embodiment of this application, a receiving section is provided above the receiving platform. The receiving section includes a receiving fork and a fourth drive assembly. The fourth drive assembly is configured to drive the receiving fork to move horizontally or vertically. The receiving fork is located on the side of the limiting member relative to the receiving block. The limiting member has a slot with an opening at the lower end. The receiving fork has two insert rods that can be inserted into the slot. The distance between the two insert rods is greater than the width of the receiving block. When the receiving fork descends to the receiving position, the receiving block is located between the two insert rods. Preferably, a third support frame is provided above the conveyor line. The fourth drive assembly includes a servo screw linear module fixed above the third support frame and a second cylinder located below the third support frame and horizontally arranged. The output end of the servo screw linear module is fixedly connected to the second cylinder, and the telescopic rod of the second cylinder is fixedly connected to the receiving fork. Once the receiving block receives a preset number of battery plates, it descends below the conveyor line, and the plate modules land directly on the line. As the receiving block descends, the receiving fork descends to the receiving height, and the conveyor line continues to deliver battery plates, which are temporarily received by the receiving fork. After the plate modules on the receiving block are removed, the receiving block rises to support the plate modules that are forming above it. Finally, the receiving fork moves to the top of the receiving block in a descending → retracting → rising → forward motion.

[0011] In one embodiment of this application, the receiving device includes a second tapping section. The second tapping section comprises a third push plate located on the side of the receiving block opposite the limiting member, and a fourth push plate and a baffle respectively located on both sides of the receiving block. The third and fourth push plates are driven by their respective cylinders to move towards or away from the receiving block. During the receiving process of the receiving device, the second tapping section performs preliminary pre-sorting of the battery plates, thereby shortening the sorting cycle time of the sorting device and improving the sorting effect and speed.

[0012] In one embodiment of this application, the limiting member includes a fixed plate, a limiting plate, and a steel sheet. The limiting plate is fixed to one side of the fixed plate corresponding to the receiving pier, and the limiting plate is also fixed to the other side of the fixed plate. Both the limiting plate and the steel sheet have downwardly extending forks, forming a cavity between the steel sheet and the forks of the limiting plate. When the battery plate impacts the steel sheet, the steel sheet undergoes elastic deformation to provide cushioning, preventing damage to the battery plate. Attached Figure Description

Detailed Implementation

[0014] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description. Example

[0015] like Figure 1 As shown, battery electrode A is stacked to a certain height to form electrode module B. Figure 2 The stacking and sorting unit shown includes a conveyor line 10 and a stacking device 20 and a sorting device 30 disposed above the conveyor line 10, for stacking a plurality of battery electrode sheets A into an electrode module B and sorting the electrode module B flat.

[0016] like Figure 3 and 5As shown, the receiving device 20 includes a receiving platform 21 and a first drive assembly 22. The receiving platform 21 includes a limiting member 211 and a receiving block 212. The limiting member 211 is located on the side of the receiving block 212 opposite to the incoming material direction. The battery electrode sheets are conveyed from the front end of the line and are blocked by the limiting member 211 before falling onto the receiving block 212. After each receiving, the first drive assembly 22 drives the receiving block 212 to descend by a certain height to keep the receiving height consistent. After the stacking of one electrode module is completed, the first drive assembly drives the receiving block to descend below the conveyor line 10, and the electrode module automatically falls onto the conveyor line. The limiting member 211 includes a mounting plate 211a, a limiting plate 211b, and a steel sheet 211c. The limiting plate is fixed to one side of the mounting plate corresponding to the receiving block, and the limiting plate is fixed to the other side of the mounting plate. Both the limiting plate and the steel sheet have downwardly extending forks, and a cavity 211d is formed between the steel sheet 211c and the forks of the limiting plate. When the battery plates collide with the steel sheet, the steel sheet undergoes elastic deformation to provide cushioning and prevent damage to the battery plates.

[0017] The first drive assembly 22 is located below the conveyor line 10 and includes a servo motor 221, a spur gear 222, and a cylindrical rack 223. A second support frame 40 is located below the conveyor line 10. A guide rod 50 is positioned between the upper and lower plates of the second support frame. A support member 60 is located below the receiving block 212, and the support member 60 is fixedly connected to the bushing on the guide rod 50. The top of the cylindrical rack is fixedly connected to the support member, and its side is meshed with the spur gear. The servo motor 221 is located below the lower plate, and the cylindrical rack 223 passes through the lower plate and meshes with the spur gear. The output shaft of the servo motor is connected to the spur gear. The first drive assembly, as the lifting power source for the receiving block, uses a combination of spur gear and cylindrical rack structure to ensure the repeatability and stability of the receiving block's lifting, improve the quality of the battery electrode plate stacking, and prevent damage to the battery electrodes in this process.

[0018] During the process of the receiving pier 212 descending into the conveyor line, the front-end line needs to be stopped to prevent the battery plates from being conveyed onto the receiving pier 212. In this embodiment, a receiving section 24 is provided above the receiving platform 21, which works in conjunction with the receiving platform to ensure that the front-end line does not stop.

[0019] like Figure 4 and 6As shown, the receiving section 24 includes a receiving fork 241 and a fourth drive assembly 242. The fourth drive assembly is configured to drive the receiving fork 241 to move horizontally or vertically. The receiving fork is located on the side of the limiting member relative to the receiving block. The limiting member has a slot 211e with an opening at the lower end. The receiving fork has two insert rods 241a that can be inserted into the slot. The distance between the two insert rods is greater than the width of the receiving block. When the receiving fork 241 moves down to the receiving position, the receiving block is located between the two insert rods. Preferably, a third support frame 70 is provided above the conveyor line. The fourth drive assembly includes a servo screw linear module 242a fixed above the third support frame and a second cylinder 242b located below the third support frame and horizontally arranged. The output end of the servo screw linear module is fixedly connected to the second cylinder, and the telescopic rod of the second cylinder is fixedly connected to the receiving fork. Once the receiving block receives a preset number of battery plates, it descends below the conveyor line, and the plate modules land directly on the conveyor line. As the receiving block descends, the receiving fork 241 descends to the receiving height, and the conveyor line continues to deliver battery plates, which are temporarily received by the receiving fork. After the plate modules on the receiving block are removed, the receiving block rises to support the plate modules that are being stacked above. Finally, the receiving fork moves to the top of the receiving block according to the actions of descending, retracting, rising, and advancing, and the receiving block continues to stack and collect the plates.

[0020] like Figure 7-8 As shown, the sorting device 30 includes a flipping part 31 and a first tapping part 32 located above the flipping part.

[0021] like Figure 9 As shown, the flipping part 31 includes a flipping member 311 and a second driving assembly 312. The second driving assembly is configured to drive the flipping member 311 to rotate around a central axis 313. A carrier plate 314 is disposed in the receiving cavity of the flipping member. The carrier plate and the flipping member are connected by an elastic member 315. A vibration motor 316 connected to the carrier plate is disposed in the flipping member. Preferably, the flipping member includes a base 311a, a first support plate 311b, and a second support plate 311c. The base is fixedly connected to the central axis. The fixed ends of the first and second support plates are fixedly connected to the base, and their bearing ends extend in the opposite direction and together with the base form a receiving cavity. The carrier plate 314 is located between the first and second support plates. When the cavity opening faces the receiving device, the first pallet is located in the conveyor line. The electrode module moves with the conveyor line to the top of the first pallet 311b. After the electrode module enters the cavity, the flipping component flips upward 90° to switch the electrode module to an upright state. The first pallet and the second pallet are located on both sides of the electrode module. After the electrode module is patted and sorted, the flipping component flips downward 90° to switch the electrode module to a horizontal state. The second pallet 311c is located in the conveyor line. The electrode module moves backward with the conveyor line to leave the cavity and complete the unloading.

[0022] The base 311a has a square hollow structure. A connecting plate is provided on one side of the base 311a corresponding to the carrier plate 314. The connecting plate has bent ears that attach to the outside of the base 311a, and the connecting plate is connected to the base through the ears. An elastic element 315 is provided between the carrier plate 314 and the connecting plate 311d. The vibration motor 316 is located inside the base 311a, and the connecting plate 311d has a clearance hole corresponding to the vibration motor 316. By disconnecting the ears from the base, the carrier plate 314 and the vibration motor can be removed together. The modular design of the carrier plate and the vibration motor facilitates debugging.

[0023] like Figure 8 As shown, the first tapping part 32 includes a third driving assembly 321 and a first push plate 322 and a second push plate 323 arranged opposite to each other. The flipping member 311 flips upward by 90°, and the first push plate and the second push plate are located on both sides of the receiving cavity. The first support frame 33 of the sorting device is provided with a guide rod 34 located above the central axis. A downwardly extending fixed plate 211a is installed on the guide bushing fitted on the guide rod. The first push plate 322 and the second push plate 323 are fixedly connected to the corresponding fixed plate 2. The telescopic rods of the two first cylinders in the third driving assembly are respectively connected to the first push plate and the second push plate, driving the first push plate and the second push plate to move relatively synchronously closer or relatively synchronously further apart. The battery plates have tabs. When the plate module is in an upright state, the tabs face the first push plate. The push block 325 provided on the inner side of the first push plate contacts the part below the tab of the plate module during the tapping process. The push block 325 and the second push plate 323 together complete the tapping and sorting of the plate module.

[0024] The working process of the sorting device is as follows: The electrode module enters the receiving cavity of the flipping member 311 along the conveyor line 10. The second drive assembly 312 drives the flipping member 311 to flip upward by 90°, and the electrode module is in an upright state. The third drive assembly 321 drives the first push plate 322 and the second push plate 323 to quickly tap the electrode module to straighten it. The second drive assembly 312 drives the flipping member 311 to flip downward by 90°, and the electrode module switches from an upright state to a horizontal state, and the electrode module falls back onto the conveyor line 10.

[0025] In another implementation, such as Figure 4 As shown, the receiving device 20 includes a second tapping section 26, which comprises a third push plate 261 located on the side of the receiving block 212 opposite to the limiting member 211, and a fourth push plate 262 and a baffle 263 located on both sides of the receiving block 212. The third and fourth push plates are driven by their respective cylinders to move towards or away from the receiving block 212. During the process of the receiving device receiving battery plates, the second tapping section performs preliminary pre-sorting of the battery plates, thereby shortening the sorting cycle of the sorting device and improving the sorting effect and speed.
