Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to battery cell feeding and sorting equipment. Background Technology

[0002] Traditional equipment often lacks standardized docking designs between the hopper discharge end, the conveyor feed end, and the testing station, frequently resulting in obstructed cell transfer due to height differences and positional deviations. The independent control of each module's operation in traditional equipment, lacking a unified control system, easily leads to problems such as overfeeding in the preceding stage or insufficient material in the subsequent stage. Cells are prone to positional shifts due to vibration and speed fluctuations, causing inaccurate alignment of the testing end with the cell electrodes. Traditional flipping mechanisms often employ mechanical stop limits, which cannot precisely control the flipping angle, resulting in technical issues such as cell posture deviation after flipping.

[0010] Furthermore, the transverse transmission belt unit 3012, the vertical transmission belt unit 3022, and the locking transmission belt unit 402 have the same structure, each consisting of a transmission frame 7, a drive shaft 8 and a driven shaft 9 respectively mounted on both ends of the transmission frame 7, a transmission belt 10 mounted on the drive shaft 8 and the driven shaft 9, a driven wheel 11 coaxial with the drive shaft 8, a drive motor 12 mounted on the transmission frame 7 and located near the drive shaft 8, a drive wheel 13 mounted on the drive motor 12, and a belt 14 mounted on the drive wheel 13 and the driven wheel 11.

[0022] The technical solutions of the battery cell feeding and sorting equipment provided by this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] refer to Figure 1 As shown, the battery cell feeding and sorting equipment is used to complete the processes of battery cell warehousing, sorting and flipping. The equipment includes: an operating table 1, which provides a mounting carrier for the various components of the equipment.

[0024] In this embodiment, the battery cell feeding and sorting equipment needs to simultaneously complete multiple precision processes such as outbound processing, sorting, and flipping, involving the coordinated operation of multiple functional components such as the conveying mechanism, sorting module, and flipping assembly. The operating table 1 provides a unified, flat, and high-strength installation reference surface, ensuring precise alignment of each component during installation. For example, key parameters such as the levelness of the conveyor track, the spacing of the sorting mechanism, and the rotation axis height of the flipping assembly can all be standardized and calibrated using the operating table 1, effectively avoiding problems such as battery cell jamming, large sorting errors, and flipping angle deviations caused by component misalignment. Simultaneously, the rigid structure of the operating table 1 can disperse the vibration and impact forces generated during the operation of each component, reducing resonance interference between components and providing a stable structural guarantee for the long-term high-precision operation of the equipment, thereby improving the pass rate and process efficiency of battery cell sorting.

[0025] refer to Figure 2 As shown, the equipment also includes at least one battery cell storage mechanism 2, which is used to store battery cells and provide battery cell raw materials for subsequent preset processes.

[0026] Furthermore, the battery cell hopper mechanism 2 includes: a mounting back plate 201, which is vertically fixedly mounted on the operating table 1; the mounting back plate 201 provides a mounting carrier for each component of the battery cell hopper mechanism 2; a conical hopper 202 for storing battery cells; the conical hopper 202 is fixedly mounted on the mounting back plate 201; an adjusting block 203 for adjusting the size and discharge volume of the conical hopper 202 outlet to accommodate different battery cell models; the adjusting block 203 is mounted on the conical hopper 202 and located at the upper end of the conical hopper 202 outlet, and the adjusting block 203 adjusts the size and discharge volume of the conical hopper 202 outlet by adjusting its installation position inward or outward from the conical hopper 202; and a receiving mechanism. Plate 204 is used to receive the battery cells one by one in the conical hopper 202; the receiving plate 204 is fixedly installed on the mounting back plate 201, and the receiving plate 204 is provided with a receiving groove 205; a pushing cylinder 206 is fixedly installed on the receiving plate 204; a pushing plate 207 is used to push the battery cells located in the receiving groove 205 one by one onto the battery cell conveying mechanism 3; the pushing plate 207 is located on the telescopic end of the pushing cylinder 206: wherein, after each battery cell comes out from the outlet of the conical hopper 202, it falls onto the receiving groove 205 to wait, the pushing cylinder 206 drives the pushing plate 207, and the pushing plate 207 pushes the battery cells located in the receiving groove 205 onto the battery cell conveying mechanism 3, completing the battery cell out-of-warehouse process.

[0027] Specifically, operators adjust the installation position of the adjusting block 203 to match the parameters according to the model of the battery cells to be sorted. Pushing the adjusting block 203 into the conical hopper 202 reduces the outlet space, accommodating smaller diameter / size cells; pulling the adjusting block 203 outward expands the outlet space, accommodating larger cells. This ensures a precise match between the hopper outlet size and the cell specifications, guaranteeing that only one cell is output at a time, preventing jamming or stacking. Simultaneously, batches of cells are poured into the conical hopper 202, where they naturally stack under their own weight, awaiting the release command. When the equipment initiates the release process, the cells in the conical hopper 202 fall one by one from the adjusted outlet under gravity, precisely landing in the receiving groove 205 of the receiving plate 204 below. The size of the receiving groove 205 matches the current cell model, stably supporting each cell and limiting its position, preventing displacement or falling. At this time, the pushing cylinder 206 receives a control signal, and its telescopic end drives the pushing plate 207 to move horizontally. After the pushing plate 207 contacts the battery cell in the receiving groove 205, it smoothly pushes it onto the connected battery cell conveying mechanism 3. After the pushing is completed, the pushing cylinder 206 drives the pushing plate 207 to reset, waiting for the next battery cell to fall into the receiving groove 205, and enters the next pushing cycle, continuously feeding raw materials for subsequent sorting and flipping processes.

[0028] In this embodiment, the battery cell hopper mechanism 2 serves as the source storage station for battery cell supply. The conical hopper 202 can store batches of battery cells, eliminating the need for frequent manual replenishment by operators and providing uninterrupted raw material support for subsequent sorting and flipping processes. Through the adjustable design of the adjusting block 203, the mechanism can quickly adapt to different specifications of battery cells: without replacing the hopper body or modifying the structure, parameter switching can be completed simply by manually adjusting the position of the adjusting block. This design significantly reduces equipment changeover costs and improves equipment versatility; the same sorting machine can meet the production needs of different battery cell models. The combination of the single-cell receiving design of the receiving trough 205 and the directional pushing function of the pusher plate 207 ensures that each battery cell enters the conveying mechanism 3 individually, orderly, and precisely positioned. On the one hand, this avoids material jamming caused by multiple battery cells stacked out of the warehouse; on the other hand, the uniform pushing action of the pusher cylinder 206 reduces collisions between battery cells and components, lowering the risk of scratches on the battery cell casing and damage to the internal battery cells, thus improving the pass rate of the sorted battery cells.

[0029] refer to Figures 3-4 As shown, the equipment also includes a cell conveying mechanism 3, which is used to convey the cells discharged from the cell hopper mechanism 2 to the sorting and turning process.

[0030] Furthermore, the cell conveying mechanism 3 is composed of a horizontal conveying mechanism 301 and a vertical conveying mechanism 302 that are perpendicular to each other and have different widths; the horizontal conveying mechanism 301 is located above the vertical conveying mechanism 302; the horizontal conveying mechanism 301 is used to convey the cells arranged side by side, and the horizontal conveying mechanism 301 converts the cells arranged side by side into cells connected end to end, and transmits them one by one to the vertical conveying mechanism 302; the vertical conveying mechanism 302 is used to convey the cells connected end to end, and convey them to the positioning transmission mechanism 4.

[0031] Furthermore, the transverse conveying mechanism 301 includes: a transverse mounting bracket 3011, which provides a mounting carrier for each component of the transverse conveying mechanism 301; the transverse mounting bracket 3011 is vertically mounted on the operating table 1; a transverse transmission belt unit 3012, which is mounted on the transverse mounting bracket 3011; the width of the transverse transmission belt unit 3012 is the same as the length of the battery cell; at least two transverse baffles 3013, which are mounted on both sides of the transverse transmission belt unit 3012; the transverse baffles 3013 are used to prevent the battery cell from detaching from the transverse transmission belt unit 3012; at least two steering guide blocks 3014, which are mounted on one end of the transverse transmission belt unit 3012 near the vertical conveying mechanism 302; the steering guide blocks 3014 have steering grooves 3015 on their opposite sides to change the arrangement of the battery cells from side-by-side to end-to-end.

[0032] refer to Figures 7-9 As shown, the transverse transmission belt unit 3012 further comprises a transmission frame 7, a drive shaft 8 and a driven shaft 9 respectively mounted on both ends of the transmission frame 7, a transmission belt 10 mounted on the drive shaft 8 and the driven shaft 9, a driven pulley 11 coaxial with the drive shaft 8, a drive motor 12 mounted on the transmission frame 7 and located near the end of the drive shaft 8, a drive pulley 13 mounted on the drive motor 12, and a belt 14 mounted on the drive pulley 13 and the driven pulley 11.

[0033] Specifically, when the equipment starts, the drive motor 12 of the transverse transmission belt unit 3012 is energized and rotates, driving the drive wheel on the motor output shaft to rotate. The drive wheel 13 transmits power to the driven wheel 11, which is coaxial with the drive shaft 8, through the belt 14, thereby driving the drive shaft 8 to rotate. The drive shaft 8 drives the transmission belt 10 mounted on it to rotate cyclically through friction, while the driven shaft 9 rotates synchronously with the transmission belt 10, providing stable power for transverse conveying. After the pusher plate 207 of the battery cell hopper mechanism 2 pushes a single battery cell to the feed end of the transverse transmission belt unit 3012, the battery cell moves along the conveying direction with the transmission belt 10. Since the width of the transverse transmission belt unit 3012 is the same as the length of the battery cell, and transverse baffles 3013 are installed on both sides, the left and right deviation of the battery cell during the conveying process can be effectively limited, preventing the battery cell from falling off the edge of the transmission belt and ensuring that the battery cell is always stably conveyed along the preset path. At this stage, if multiple battery cell hopper mechanisms 2 supply material at the same time, the battery cells will be arranged side by side on the transmission belt 10. When the parallel-arranged battery cells are conveyed by the drive belt 10 to one end near the vertical conveying mechanism 302, they enter the working range of the steering guide block 3014. The opposing sides of the two steering guide blocks 3014 are provided with steering grooves 3015, the width of which matches the length of a single battery cell. Under the thrust of the drive belt 10, the parallel-arranged battery cells enter the steering grooves 3015 one by one, changing their direction of movement along the grooves, ultimately changing from a parallel arrangement to an end-to-end arrangement, forming a single-row orderly battery cell queue, preparing for subsequent vertical conveying.

[0034] In this embodiment, the transverse conveying mechanism 301 serves as a bridge between the battery cell hopper mechanism 2 and the sorting and flipping processes. The battery cell conveying mechanism 3 can receive individual batteries output from the hopper mechanism 2 in real time and transfer them to subsequent processes through orderly conveying. On the one hand, this avoids the problem of battery cells accumulating and clogging after being discharged from the hopper mechanism 2; on the other hand, directional conveying ensures that the batteries accurately enter the positioning transmission mechanism 4, providing a stable supply of materials to be processed for the sorting equipment and the flipping mechanism, preventing process interruptions caused by battery cell position deviation, and ensuring the continuity of the entire equipment process from "feeding-conveying-sorting-flipping".

[0035] Furthermore, the vertical conveying mechanism 302 includes: a vertical mounting bracket 3021, which provides a mounting carrier for each component of the vertical conveying mechanism 302; the vertical mounting bracket 3021 is vertically mounted on the operating table 1; a vertical transmission belt unit 3022, which is mounted on the vertical mounting bracket 3021; ​​the width of the vertical transmission belt unit 3022 is the same as the width of the battery cell; at least two vertical baffles 3023, which are installed on both sides of the vertical transmission belt unit 3022; the vertical...

[0036] Furthermore, the vertical transmission belt unit 3022 consists of a transmission frame 7, a drive shaft 8 and a driven shaft 9 respectively mounted on both ends of the transmission frame 7, a transmission belt 10 mounted on the drive shaft 8 and the driven shaft 9, a driven wheel 11 coaxial with the drive shaft 8, a drive motor 12 mounted on the transmission frame 7 and located near the end of the drive shaft 8, a drive wheel 13 mounted on the drive motor 12, and a belt 14 mounted on the drive wheel 13 and the driven wheel 11.

[0037] refer to Figure 9 As shown, the horizontal transmission belt unit 3012 and the vertical transmission belt unit 3022 also have a tensioning structure 15. The tensioning structure 15 consists of a tensioning wheel 1501 and two auxiliary wheels 1502 mounted on the transmission frame 7. The tensioning structure 15 is used to keep the transmission belt 10 in a suitable tension state during rotation.

[0038] Specifically, the power transmission logic of the vertical transmission belt unit 3022 is the same as that of the horizontal transmission belt unit 3012. The startup process is as follows: After the equipment is powered on, the drive motor 12 mounted on the transmission frame 7 operates, driving the drive wheel 13 on the motor output shaft to rotate; the drive wheel 13 transmits power to the driven wheel 11 coaxial with the drive shaft 8 through the belt 14, thereby driving the drive shaft 8 to rotate; the drive shaft 8 drives the transmission belt 10 mounted on it to rotate in a cycle by means of friction, and the driven shaft 9 rotates synchronously with the transmission belt 10, finally forming a stable vertical conveying power. The running direction of the transmission belt 10 is towards the positioning transmission mechanism 4, laying the foundation for the cell conveying. When the steering guide block 3014 of the horizontal conveying mechanism 301 converts the parallel cells into a head-to-tail state and pushes them to the end of the horizontal transmission belt unit 3012, the cells fall down to the vertical transmission belt unit 3022 due to the conveying inertia. The stop-drive cylinder 3025, mounted on mounting post 3024, receives a control signal in advance. Its telescopic end extends, driving the anti-detachment stop 3026 to move to the edge of the vertical transmission belt unit 3022 near the steering guide block 3014, forming a lateral blocking barrier. During the battery cell's descent, if it tends to shift laterally due to inertia, the anti-detachment stop 3026 will directly block the battery cell, preventing it from detaching from the edge of the vertical transmission belt unit 3022. At the same time, the vertical baffles 3023 on both sides of the vertical transmission belt unit 3022 further restrict the battery cell's lateral shift, ensuring that the battery cell lands precisely in the center area of ​​the transmission belt 10, completing the receiving process. After the battery cell lands stably on the transmission belt 10 and is conveyed forward with it, the telescopic end of the stop-drive cylinder 3025 retracts, driving the anti-detachment stop 3026 to reset, reserving space for the next battery cell to land, forming a cyclical protection system. After the battery cell lands on the transmission belt 10 of the vertical transmission belt unit 3022, since the width of the transmission belt 10 is the same as the width of the battery cell, and there are vertical baffles 3023 on both sides, the battery cell will not sway or deviate during the conveying process, and will always maintain an end-to-end arrangement along the preset path. At this stage, the running speed of the transmission belt 10 is coordinated with the conveying speed of the horizontal conveying mechanism 301 and the subsequent pushing rhythm to avoid the problem of battery cells piling up or having too large a gap on the transmission belt 10, thus preparing for subsequent precise pushing. The blocking block 30211 installed at the end of the vertical conveying mechanism 302 first plays its role, blocking the battery cell at the front from continuing to move with the transmission belt 10, preventing the battery cell from detaching from the end, and at the same time keeping the subsequent battery cells in an end-to-end state, forming a queue to be pushed. The push plate drive cylinder 3028 installed on the second mounting column 3027 receives the signal, its telescopic end extends, and drives the push plate 3029 to move towards the battery cell. After the pusher plate 3029 contacts the foremost battery cell, it pushes it toward the inclined guide plate 30210. Under the pushing force of the pusher plate 3029, the battery cell rolls down along the inclined surface of the inclined guide plate 30210 and finally falls precisely into the preset locking position of the locking transmission mechanism 4.After a single battery cell is pushed out, the telescopic end of the pusher drive cylinder 3028 retracts, causing the pusher 3029 to reset; the transmission belt 10 continues to transport the next battery cell forward, causing it to stop at the block 30211 and enter the next round of pushing cycle, continuously supplying battery cells to the positioning transmission mechanism 4.

[0039] In this embodiment, compared to the traditional conveying mechanism that relies solely on baffles for protection, the vertical conveying mechanism 302 features an additional anti-detachment block 3026 that, together with the vertical baffle 3023, provides dual lateral protection. The anti-detachment block 3026 addresses the inertial offset issue when the battery cell falls from the horizontal mechanism, providing precise blocking at the moment of impact to prevent scratches on the casing or damage to the battery cell due to offset during drop. The vertical baffle 3023 continuously restricts the lateral movement of the battery cell during conveying, preventing wear caused by collisions between the battery cell and the baffle. The width of the vertical drive belt unit 3022 is precisely matched to the width of the battery cell, and with the constraint of the vertical baffle 3023, the battery cell maintains a straight posture and uniform spacing during conveying, preventing rotation or tilting due to an excessively wide drive belt, or compression deformation due to an excessively narrow belt. This standardized arrangement directly meets the requirement of the sorting process for individual cells to pass through the inspection station sequentially, eliminating the need for subsequent adjustments to the cell posture and avoiding inspection errors caused by posture confusion, thus improving sorting accuracy and efficiency. The collaborative design of the push plate 3029 and the inclined guide plate 30210 solves the problem of easy displacement when cells directly fall into the clamping position in traditional conveying mechanisms: the push plate 3029 provides stable thrust through cylinder drive, ensuring that the cells move in a fixed direction; the inclined structure of the inclined guide plate 30210 uses gravity to assist the cells to roll smoothly, avoiding positional displacement caused by hard collisions between the cells and the clamping mechanism. At the same time, the limiting effect of the blocking block 30211 keeps the cells in a fixed position waiting to be pushed, ensuring that each cell can accurately fall into the preset clamping position of the clamping transmission mechanism 4, avoiding process interruptions caused by docking deviations and ensuring the continuity of the overall equipment process.

[0040] refer to Figure 5 As shown, the equipment also includes a positioning and transmission mechanism 4, which is used to clamp the battery cells in the clamping positions and convey them. As a key hub for battery cell positioning and directional conveying in the battery cell feeding and sorting equipment, the positioning and transmission mechanism 4 relies on the stable structure built by the clamping mounting bracket 401, combined with the coordinated design of the clamping transmission belt unit 402 and the clamping block 403, to achieve precise positioning and smooth conveying of the battery cells from the vertical conveying mechanism 302 to the sorting and flipping processes.

[0041] Furthermore, the positioning transmission mechanism 4 includes: a positioning mounting bracket 401, which provides a mounting carrier for each component of the positioning transmission mechanism 4; a vertical mounting bracket 3021, which is vertically mounted on the operating table 1; a positioning transmission belt unit 402, which is mounted on the positioning mounting bracket 401; the width of the positioning transmission belt unit 402 is the same as the length of the battery cell; a plurality of positioning blocks 403, each arranged in sequence according to the spacing of the battery cell width on both sides of the positioning transmission belt unit 402; two adjacent positioning blocks 403 and two adjacent positioning blocks 403 on opposite sides form a positioning groove 404.

[0042] Furthermore, the positioning transmission belt unit 402 consists of a transmission frame 7, a drive shaft 8 and a driven shaft 9 respectively mounted on both ends of the transmission frame 7, a transmission belt 10 mounted on the drive shaft 8 and the driven shaft 9, a driven wheel 11 coaxial with the drive shaft 8, a drive motor 12 mounted on the transmission frame 7 and located near the end of the drive shaft 8, a drive wheel 13 mounted on the drive motor 12, and a belt 14 mounted on the drive wheel 13 and the driven wheel 11.

[0043] Specifically, the power transmission logic of the positioning transmission belt unit 402 is the same as that of the vertical transmission belt unit 3022. The startup process is as follows: After the equipment is powered on, the drive motor 12 mounted on the transmission frame 7 runs, driving the drive wheel 13 on the motor output shaft to rotate; the drive wheel 13 transmits power to the driven wheel 11 coaxial with the drive shaft 8 through the belt 14, thereby driving the drive shaft 8 to rotate; the drive shaft 8 drives the transmission belt 10 mounted on it to circulate by friction, and the driven shaft 9 rotates synchronously with the transmission belt 10, finally forming a stable positioning transmission power. The running direction of the transmission belt 10 is towards the sorting and flipping process, laying the foundation for the positioning and transmission of the battery cells. When the push plate 3029 of the vertical transmission mechanism 302 pushes the battery cell along the inclined guide plate 30210 to the area of ​​the positioning transmission mechanism 4, the battery cell moves towards the positioning transmission belt unit 402 by rolling inertia. Because multiple positioning blocks 403 are arranged sequentially on both sides of the positioning drive belt unit 402 according to the spacing of the battery cell width, the positioning groove 404 formed by two adjacent positioning blocks 403 and two adjacent positioning blocks 403 on the opposite side has a width that precisely matches the width of the battery cell and a depth that can accommodate a single battery cell, providing a standardized space for battery cell positioning. During the rolling process, under the lateral constraint of the positioning groove 404, the battery cell will automatically adjust its posture and fall precisely into the corresponding positioning groove 404. The positioning blocks 403 on both sides can prevent the battery cell from shifting to the left or right, avoiding the battery cell from getting stuck between the positioning blocks 403 or detaching from the positioning drive belt unit 402. At the same time, the width of the positioning drive belt unit 402 is the same as the length of the battery cell, further restricting the forward and backward movement of the battery cell, ensuring that each battery cell can be stably locked in a single positioning groove 404, completing the positioning and receiving process. The drive motor 12 maintains a constant speed, driving the transmission belt 10 to move in a predetermined direction at a preset speed. Under the continuous constraint of the positioning block 403, the battery cell in the positioning slot 404 will not shake, shift, or fall off, and will always maintain an upright posture and fixed position as it moves with the transmission belt 10. When the transmission belt 10 conveys the battery cell to the sorting process, since the battery cell is fixed in position in the positioning slot 404, the testing equipment can accurately align with the testing area of ​​the battery cell and complete parameter acquisition. Subsequently, the transmission belt 10 continues to convey the battery cell to the flipping process, providing a stable positioning foundation for the flipping mechanism to accurately grasp and flip the battery cell, realizing a seamless connection from positioning to conveying to process processing.

[0044] In this embodiment, in traditional conveying mechanisms, the battery cells are prone to positional shifts due to conveying vibrations and speed fluctuations, leading to inaccurate identification of the cells by the detection equipment during sorting and instability of the gripping mechanism during flipping. However, the positioning groove 404 of the positioning transmission mechanism 4 precisely matches the size of the battery cell, and the rigid constraint formed by the positioning blocks 403 on both sides ensures that the battery cell remains in the preset processing position during conveying, reducing rework caused by positional deviations. As the intermediate hub connecting the vertical conveying mechanism 302 with the sorting and flipping processes, the positioning transmission mechanism 4's conveying path can be flexibly designed according to the overall equipment layout, and the running speed of the transmission belt 10 can be precisely adjusted by the drive motor 12. When the flipping process requires a longer gripping time, the transmission speed can be appropriately reduced to avoid waiting or accumulation between processes. This controllable rhythm and adaptable path design enables the various processes of the equipment to operate collaboratively, significantly improving process continuity and reducing equipment downtime caused by mismatched process rhythms.

[0045] refer to Figure 6 As shown, the equipment also includes a voltage detection and sorting mechanism 5, which is used to detect the voltage of the battery cells. If a battery cell with an unqualified voltage is found, it will be rejected. The voltage detection and sorting mechanism 5, as the core of the battery cell feeding and sorting equipment, relies on the coordinated operation with the positioning and transmission mechanism 4, and through the cooperation of the voltage detection platform and the sorting drive components, to achieve accurate detection of the battery cell voltage and efficient rejection of unqualified battery cells.

[0046] Furthermore, the voltage detection and sorting mechanism 5 includes: two voltage detection platforms 501, which are respectively mounted opposite each other on both sides of the positioning transmission belt unit 402; a positive detection electrode 502 and a negative detection electrode 503, which are respectively mounted on the two voltage detection platforms 501, and the positive detection electrode 502 and the negative detection electrode 503 are used to measure whether the voltage of the battery cell meets the preset voltage; a collection slot 504, which is fixedly mounted on the operating table 1; a sorting drive cylinder 505, which is fixedly mounted on the positioning transmission belt unit 402 and corresponds to the collection slot 504; and a sorting rejection plate 506, which is mounted on the telescopic end of the sorting drive cylinder 505; wherein, when the positive detection electrode 502 and the negative detection electrode 503 detect a battery cell that does not meet the preset voltage, the positioning transmission mechanism 4 stops moving, and the sorting drive cylinder 505 is activated to drive the sorting rejection plate 506, pushing the battery cell that does not meet the preset voltage into the collection slot 504.

[0047] Specifically, the positive detection electrode 502 and negative detection electrode 503 installed on the two relative voltage detection platforms 501 are pre-adjusted according to the model of the battery cell being tested, ensuring that the two detection ends can be accurately aligned with the positive and negative terminals of the battery cell when it enters the testing area. When a cylindrical battery cell is being tested, the positive detection electrode 502 is aligned with the positive terminal at the top of the battery cell, and the negative detection electrode 503 is aligned with the negative terminal on the side of the battery cell, preparing the position for subsequent voltage measurement. The sorting drive cylinder 505 is in its initial retracted state, driving the sorting rejection plate 506 to stop on the side of the clamping transmission belt unit 402 without affecting the normal transmission of the battery cell; the collection slot 504 fixed on the operating table 1 keeps its opening facing upward, and the slot opening is aligned with the pushing direction of the sorting rejection plate 506, ensuring that the rejected battery cell can fall accurately into the slot, completing the component standby before sorting. The positioning conveyor belt unit 402 moves at a preset speed. When the positive and negative terminals of a single battery cell are fully aligned with the positive detection electrode 502 and the negative detection electrode 503, the drive motor 12 of the positioning transmission mechanism 4 receives a control signal, and the conveyor belt 10 stops operating. This ensures that the battery cell remains stationary during the testing process, preventing poor contact between the detection tip and the electrodes due to movement. Under the thrust of a cylinder or spring, the positive detection electrode 502 and the negative detection electrode 503 make slight contact with the positive and negative terminals of the battery cell. The built-in voltage detection module collects the real-time voltage data of the battery cell and transmits the data to the equipment control system for comparison with the preset qualified voltage range. If the detected battery cell voltage is within the preset qualified range, the control system sends a continue operation signal to the positioning transmission mechanism 4, the drive motor 12 restarts, and the conveyor belt 10 carries the qualified battery cell away from the testing area to continue to the subsequent flipping process. At the same time, the voltage detection tip resets, waiting for the next battery cell to enter the testing area. If the detected cell voltage is lower or higher than the preset acceptable range, the control system immediately triggers a sorting command: First, the clamping transmission mechanism 4 is kept stationary to prevent unqualified cells from moving with the transmission belt; then, an extension signal is sent to the sorting drive cylinder 505 to start the sorting process. The pushing surface of the sorting rejection plate 506 is in contact with the side of the cell, and under the thrust of the cylinder, the unqualified cell is smoothly pushed out of the clamping slot 404. Since the sorting drive cylinder 505 corresponds to the collection slot 504, the pushed-out cell moves along the preset direction and finally falls precisely into the collection slot 504, completing the physical separation of the unqualified cell. After the unqualified cell falls into the collection slot 504, the extension end of the sorting drive cylinder 505 retracts, driving the sorting rejection plate 506 to reset to the initial position; at the same time, the control system sends a restart signal to the clamping transmission mechanism 4, and the transmission belt 10 continues to operate, conveying the next cell into the detection area, starting the next cycle from detection to judgment to processing.

[0048] Traditional manual voltage testing of battery cells is prone to human error, such as poor contact at the testing terminals or data reading errors, leading to defective cells flowing into subsequent processes and affecting the final product quality. This new mechanism, however, uses precise alignment of the positive and negative testing electrodes 502 and 503, combined with automated data acquisition and comparison, to control voltage testing errors within a preset range, ensuring accurate determination of the voltage parameters of each battery cell. Furthermore, the immediate rejection design for defective cells intercepts under-voltage and over-voltage cells, preventing them from entering subsequent processes such as flipping and assembly, thus ensuring the quality stability of the battery cell products from the source.

[0049] The equipment also includes a vision inspection and flipping mechanism 6, which is used to detect the positive and negative poles of the battery cells. If a battery cell is found to have a different positive and negative pole orientation than the preset one, the cell with the different orientation will be flipped. As the core of the positive and negative pole orientation calibration of the battery cell feeding and sorting equipment, the vision inspection and flipping mechanism 6 relies on the straddle structure built by the cross frame bracket 601. It combines the visual recognition of the industrial camera with the flipping action of the pneumatic and electric components to achieve accurate detection of the positive and negative pole orientation of the battery cells and automated flipping of the cells with incorrect orientation.

[0050] Furthermore, the visual inspection and flipping mechanism 6 includes: a horizontal frame bracket 601, which is fixedly installed on the operating table 1 and spans across the locking transmission mechanism 4; an industrial camera 602, which is fixedly installed on the horizontal frame bracket 601, and the industrial camera 602 is used to detect the presence of the positive terminal of the battery cell; a vertical cylinder 603, which is fixedly installed on the crossbeam of the horizontal frame bracket 601; the extension end of the vertical cylinder 603 is oriented downward; a flipping mounting plate 604, which is installed on the extension end of the vertical cylinder 603; a rotary motor 605, which is installed on the flipping mounting plate 604; and a clamping cylinder 606, which is mounted on the vertical frame bracket 603. Two clamping plates 607 are mounted on the rotating end of the rotary motor 605, respectively, on the clamping end of the clamping cylinder 606. When the industrial camera 602 detects that a certain battery cell does not have a positive terminal, the clamping transmission mechanism 4 stops moving, and the vertical cylinder 603 is activated to drive the rotary motor 605 and the clamping cylinder 606 to descend. The clamping plates 607 on the clamping cylinder 606 grab the battery cell and lift it to a preset height. The rotary motor 605 is then activated to rotate the battery cell 180 degrees. After the battery cell is flipped, it is lowered onto the clamping transmission mechanism 4 by the vertical cylinder 603 and the clamping cylinder 606 is released.

[0051] Specifically, the industrial camera 602, fixed on the horizontal frame bracket 601, undergoes parameter calibration, including lens focal length adjustment, light source brightness adaptation, and import of the positive terminal feature template, ensuring accurate identification of the presence of the positive terminal of the battery cell and establishing a standard identification benchmark for subsequent testing. The vertical cylinder 603 is in its initial retracted state, driving the flip mounting plate 604, rotary motor 605, and clamping cylinder 606 to stop below the crossbeam of the horizontal frame bracket 601, maintaining a safe distance from the positioning transmission mechanism 4 to avoid affecting the normal transmission of the battery cell; the clamping cylinder 606 is in its initial open state, with the distance between the two clamping plates 607 greater than the diameter / width of the battery cell, reserving space for subsequent gripping of the battery cell, and the components are ready before flipping. The positioning transmission belt unit 402 moves at a preset speed. When a single battery cell is completely in the center of the shooting field of view of the industrial camera 602, the drive motor 12 of the positioning transmission mechanism 4 receives a control signal, and the transmission belt 10 stops operating, ensuring that the battery cell remains stationary during shooting and avoiding image blurring due to movement, which would affect the accuracy of identification. Industrial camera 602 captures high-speed images of the top of the battery cell and transmits the captured images to the equipment control system. The control system compares the captured images with a pre-stored positive terminal feature template using image algorithms. If the image contains features such as protrusions or markings that match the template, the positive and negative polarity is determined to be correct. If no corresponding features are detected, the positive and negative polarity is determined to be incorrect, and the battery cell's position information is recorded to provide a basis for subsequent flipping. If the battery cell's positive and negative polarity is determined to meet the preset requirements, the control system sends a signal to the positioning transmission mechanism 4 to continue operation, the drive motor 12 restarts, and the transmission belt 10 carries the qualified battery cell away from the visual inspection area to the next process. At the same time, industrial camera 602 resets, waiting for the next battery cell to enter the inspection area. If the battery cell's positive and negative polarity is determined to be incorrect, the control system immediately triggers a flipping command: first, the positioning transmission mechanism 4 is kept stationary to prevent the battery cell from moving and causing a deviation in the flipping position; then, action signals are sent sequentially to the vertical cylinder 603, the clamping cylinder 606, and the rotary motor 605 to start the flipping process. The telescopic end of the vertical cylinder 603 extends downwards, causing the flip mounting plate 604, rotary motor 605, and clamping cylinder 606 to descend synchronously until the two clamping plates 607 are located on both sides of the battery cell. Then, the clamping end of the clamping cylinder 606 retracts, causing the clamping plates 607 to move closer to the battery cell until they are tightly fitted against the side of the battery cell, completing the battery cell gripping. Next, the telescopic end of the vertical cylinder 603 retracts upwards, raising the battery cell to a preset height. Upon receiving a signal, the rotary motor 605 drives the clamping cylinder 606 and the gripped battery cell to rotate synchronously by 180 degrees. Since the rotating end of the rotary motor 605 is fixedly connected to the clamping cylinder 606, the rotation angle can be precisely controlled by an encoder, ensuring that the positive terminal post is accurately aligned with the preset direction after the battery cell is flipped.After the flipping is completed, the telescopic end of the vertical cylinder 603 extends downward again, smoothly placing the battery cell back into the original slot 404; then the clamping end of the clamping cylinder 606 opens, and the clamping plate 607 detaches from the battery cell; finally, the telescopic end of the vertical cylinder 603 retracts upward, driving the flipping assembly to reset to the initial standby position; the control system sends a restart signal to the clamping transmission mechanism 4, and the transmission belt 10 continues to operate, conveying the flipped battery cell and subsequent battery cells into the next round of testing, completing the entire flipping calibration process.

[0052] In subsequent processes such as battery cell assembly and charging, incorrect polarity can lead to equipment malfunctions, battery cell damage, and even safety accidents. This organization improves the accuracy of polarity identification by using high-definition image recognition from an industrial camera (602) and comparing it with feature templates. Furthermore, a precise 180-degree flip of the battery cell with incorrect polarity ensures that all cells entering subsequent processes have perfectly aligned polarities, preventing process interruptions or product scrap due to incorrect polarity and guaranteeing the smooth operation of the entire production process.

[0053] One end of the battery cell conveying mechanism 3 is located at the discharge port of the battery cell hopper mechanism 2, and the other end is connected to the positioning transmission mechanism 4; the voltage detection and sorting mechanism 5 and the vision detection and flipping mechanism 6 are both located on the positioning transmission mechanism 4, and the battery cell hopper mechanism 2, the battery cell conveying mechanism 3, and the vision detection and flipping mechanism 6 are all installed on the operating table 1.

[0054] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
