Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production equipment technology, and in particular to a correctable cell feeding device and cell assembly equipment. Background Technology
[0002] The cell assembly process is a critical step in battery production, directly impacting production efficiency and yield. During production, to prevent the cells from being scratched by the casing opening edge during assembly, thus damaging them and reducing yield, the cells are typically positioned correctly before assembly. This ensures the cells are within a predetermined range when moving to mate with the casing. However, in existing technologies, cell alignment and transfer are two relatively independent actions performed sequentially. That is, after alignment, the cell is transferred to the next process for assembly, which necessitates further improvement in production efficiency. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to design a battery cell feeding device and battery cell assembly equipment that can correct the deviation of the battery cells simultaneously during the battery cell transfer process, thereby improving production efficiency.
[0004] The objective of this utility model is achieved through the following technical solution: Design a battery cell feeding device with correctable deviation, including a transfer mechanism and a clamping and deviation correction mechanism connected to the transfer mechanism. The clamping and deviation correction mechanism is used to clamp the battery cell and correct its deviation. The transfer mechanism is used to drive the clamping and deviation correction mechanism to move during the deviation correction process of the clamping and deviation correction mechanism, so as to send the battery cell into the next process.
[0005] In this solution, by integrating the clamping, correction, and transfer functions into a single mechanism, an integrated "clamping-correction-transfer" operation process is achieved. Cell correction and transfer are performed simultaneously, significantly shortening the cell loading time and thus improving production cycle time and efficiency. Specifically, the cell is transferred from the previous process to the correctable cell loading device. The cell's position is detected by a detection unit, such as visual inspection or edge detection using photoelectric / ultrasonic sensors. The correction command is then pre-loaded directly into the control system. The control system controls the clamping and correction mechanism to clamp the cell and fine-tunes its position during clamping and transfer, achieving simultaneous cell correction and transfer actions.
[0006] Furthermore, the clamping and correction mechanism includes a clamping unit for clamping the battery cell, a first lateral movement unit for driving the clamping unit to move along a first direction, and a second lateral movement unit for driving the first lateral movement unit and the clamping unit to move along a second direction.
[0007] In this solution, two transverse units are used to control movement in different directions, making the correction action more flexible and precise. It can achieve multi-degree-of-freedom fine-tuning and dynamic compensation, and can perform real-time correction during the clamping process to adapt to minute changes in the cell's posture, further improving the accuracy and consistency of the insertion into the casing.
[0008] Furthermore, the clamping unit includes two grippers that can move closer together or open apart, and each of the two grippers has a clamping groove on its opposite side that is at least partially in contact with the sidewall of the battery cell.
[0009] In this design, the curved contour of the clamping groove fits tightly against the sidewall of the battery cell. For example, a cylindrical battery cell is matched with an arc-shaped clamping groove, which increases the contact area between the gripper and the battery cell, disperses the clamping pressure, and prevents damage to the surface coating or deformation of the internal structure of the battery cell. At the same time, the depth of the clamping groove can cover more than 1 / 3 of the height of the battery cell sidewall, forming a mechanical limiting structure, which can greatly reduce the risk of battery cell slippage under high-speed transfer or vibration conditions.
[0010] Furthermore, the transfer mechanism includes a first transfer unit for driving the gripping and correction mechanism to move along a third direction, and a second transfer unit for driving the gripping and correction mechanism and the first transfer unit to move along a first direction.
[0011] In this solution, the first transfer unit adjusts its height in real time after the battery cell is clamped, and the second transfer unit synchronously drives the entire unit to move toward the casing device, eliminating the time gap of traditional step-by-step operations, thereby improving the production cycle and efficiency of the device.
[0012] Furthermore, the second transfer unit includes a base and a support frame slidably disposed on the base in a first direction. The first transfer unit includes a support plate slidably disposed on the support frame in a third direction, and the clamping and correction mechanism is fixedly disposed on the support plate.
[0013] In this design, the base integrates horizontal movement, while the support frame supports vertical movement, eliminating the redundant supports of traditional split-type transfer mechanisms and reducing equipment size. Linear guide rails can be used for both the support frame sliding along the base and the support plate sliding along the support frame, improving the smoothness of movement. The clamping and correction mechanism is directly fixed to the support plate, forming an integral rigid frame that enhances stability during cell transfer.
[0014] A battery cell assembly device is also designed, including the above-mentioned correctable battery cell feeding device and a housing insertion device for loading the battery cell into the housing. The housing insertion device includes a battery cell adsorption mechanism for carrying the battery cell, a housing fixing mechanism for positioning and fixing the housing, and a pushing mechanism for pushing the battery cell into the housing. The housing fixing mechanism and the pushing mechanism are respectively located on two sides of the battery cell adsorption mechanism in a third direction.
[0015] In this solution, the battery cell adsorption mechanism and the pushing mechanism are aligned coaxially in a third direction, and the positioning of the housing fixing mechanism is combined to achieve a linear motion trajectory for pushing the battery cell into the housing.
[0016] Furthermore, the cell adsorption mechanism includes a cell placement platform and a negative pressure unit. The surface of the cell placement platform, which supports the cell, is provided with adsorption holes that communicate with the negative pressure unit.
[0017] In this design, the adsorption holes are arranged in an array on the surface of the battery cell placement platform. A uniform adsorption force is generated by a negative pressure unit (such as a vacuum pump), so that the battery cell is subjected to balanced force and is placed stably on the surface of the battery cell placement platform.
[0018] Furthermore, the pushing mechanism includes a punch and a punch driving unit for driving the punch to move in a third direction. The cell placement platform is provided with a punch hole, through which the punch can pass and abut against the cell, thereby pushing the cell into the housing.
[0019] In this design, the punch moves strictly along the axial direction of the punch hole (third direction) to form a mechanical limiting channel, ensuring that the pushing path coincides with the axis of the housing opening. The punch head is designed with a soft material, which can fully fit into contact with the end face of the battery cell, reducing the pressure of hard contact on a flat surface.
[0020] Furthermore, the housing fixing mechanism includes a housing placement platform and a push rod located on the side of the housing placement platform away from the cell placement platform. The housing placement platform has a through hole for accommodating the housing at the position opposite to the cell placement platform. The edge of the through hole near the push rod is provided with a fixing block that fits against the side wall of the housing. The push rod can move closer to or away from the fixing block to clamp or loosen the housing.
[0021] In this design, the sidewall of the fixing block fits tightly against the contour of the sidewall of the housing, and the push rod moves closer to or away from the fixing block along a straight line. The fixing block and the push rod together form a housing clamping assembly. Compared with traditional planar clamps, this design increases the contact area, disperses clamping stress, and avoids local deformation of the housing.
[0022] Furthermore, the housing fixing mechanism also includes two guide clamps located on the side of the housing placement platform away from the push rod and which can approach or open with each other. The two guide clamps are respectively provided with guide grooves on opposite sides, and the two guide grooves approach each other to form a guide hole, which coincides with the axis of the housing.
[0023] In this design, the guide hole formed when the guide clamp is closed is strictly aligned with the housing axis. The orifice of the guide hole can be designed as a tapered guide section. During the process of pushing the cell into the housing, even if there is a slight initial positional deviation of the cell, the mechanical constraint of the guide hole sidewall can automatically correct the deviation angle, avoiding hard scraping between the housing opening edge and the cell sidewall, which would cause scratches to the cell. In addition, the openable and closable design of the guide clamp allows for adjustment of the clamping spacing, making it compatible with battery housings of various diameters and flexibly adapting to different housing sizes.
[0024] Compared with the prior art, the beneficial effects of this utility model are: In this solution, by integrating the clamping, correction, and transfer functions into a single mechanism, an integrated "clamping-correction-transfer" operation process is achieved. Cell correction and transfer are performed simultaneously, significantly shortening the cell loading time and thus improving production cycle time and efficiency. Specifically, the cell is transferred from the previous process to the correctable cell loading device. The cell's position is detected by a detection unit, such as visual inspection or edge detection using photoelectric / ultrasonic sensors. The correction command is then pre-loaded directly into the control system. The control system controls the clamping and correction mechanism to clamp the cell and fine-tunes its position during clamping and transfer, achieving simultaneous cell correction and transfer actions.

[0032] 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. Example 1
[0033] like Figure 1 As shown, this embodiment provides a correctable battery cell feeding device 1, including a transfer mechanism 11 and a clamping and correction mechanism 12 connected to the transfer mechanism 11. The clamping and correction mechanism 12 is used to clamp the battery cell and correct its deviation. The transfer mechanism 11 is used to drive the clamping and correction mechanism 12 to move during the process of the clamping and correction mechanism 12 correcting the deviation of the battery cell, so as to send the battery cell into the next process.
[0034] By integrating clamping, correction, and transfer functions into a single mechanism, an integrated "clamping-correction-transfer" operation process is achieved. Cell correction and transfer are performed simultaneously, significantly shortening the cell loading time and thus improving production cycle time and efficiency. Specifically, the cell is transferred from the previous process to the correctable cell loading device 1. The cell position is detected by a detection unit, such as visual inspection or edge detection by photoelectric / ultrasonic sensors. The correction command is then preloaded directly into the control system. The control system controls the clamping and correction mechanism 12 to clamp the cell and fine-tune the cell position during clamping and transfer, achieving simultaneous cell correction and transfer actions.
[0035] like Figure 1As shown, the transfer mechanism 11 includes a first transfer unit 111 for driving the clamping and correction mechanism 12 to move along a third direction, and a second transfer unit 112 for driving the clamping and correction mechanism 12 and the first transfer unit 111 to move along a first direction. The second transfer unit 112 includes a base 1121 and a support frame 1122 slidably disposed on the base 1121 along the first direction. The first transfer unit 111 includes a support plate 1111 slidably disposed on the support frame 1122 along a third direction, and the clamping and correction mechanism 12 is fixedly disposed on the support plate 1111. The first transfer unit 111 adjusts its height in real time after the battery cell is clamped, and the second transfer unit 112 synchronously drives the entire assembly to move towards the housing device 2, eliminating the time gap of traditional step-by-step operations, thereby improving the production cycle and production efficiency of the device. The base 1121 integrates horizontal movement, while the support frame 1122 supports vertical movement, eliminating the redundant supports of traditional split-type transfer mechanisms and reducing equipment size. Linear guide rails can be used for both the sliding of the support frame 1122 along the base 1121 and the sliding of the support plate 1111 along the support frame 1122, improving the smoothness of movement. The clamping and correction mechanism 12 is directly fixed to the support plate 1111, forming an integral rigid frame and enhancing stability during cell transfer.
[0036] Specifically, in this embodiment, both the first transfer unit 111 and the second transfer unit 112 are driven by linear motors. Specifically, a stator assembly is integrated on the base 1121 of the second transfer unit 112, forming a magnetic field track in a first direction. A mover assembly is fixed to the bottom of the support frame 1122, which is slidably connected to the base 1121 via a linear slide rail. After being energized, the mover interacts with the stator magnetic field to generate a driving force, driving the support frame 1122 to slide along the first direction on the base 1121. A stator assembly is installed on the support frame 1122, forming a magnetic field track in a third direction. A mover assembly is fixed to the back of the support plate 1111, which is slidably connected to the support frame 1122 via a linear slide rail. After being energized, the mover interacts with the stator magnetic field to generate a driving force, driving the support plate 1111 to rise and fall in a third direction.
[0037] It should be noted that the driving form of the first transfer unit 111 and the second transfer unit 112 is not limited to linear motor drive. As long as linear motion in the first direction and the third direction are achieved respectively, other possible embodiments may also adopt a driving form combining a drive motor and a lead screw, or a cylinder drive, etc., without specific limitations here.
[0038] like Figure 2As shown, the clamping and correction mechanism 12 is fixedly mounted on the support plate 1111. The clamping and correction mechanism 12 includes a clamping unit 121 for clamping the battery cell, a first lateral movement unit 122 for driving the clamping unit 121 to move along a first direction, and a second lateral movement unit 123 for driving the first lateral movement unit 122 and the clamping unit 121 to move along a second direction. By using two lateral movement units to control movement in different directions, the correction action becomes more flexible and precise, enabling multi-degree-of-freedom fine-tuning and dynamic compensation. Real-time correction can be performed during the clamping process to adapt to minute changes in the battery cell's posture, further improving the accuracy and consistency of the battery cell insertion.
[0039] In this embodiment, both the first lateral movement unit 122 and the second lateral movement unit 123 are driven by a drive motor and a lead screw. Specifically, the second lateral movement unit 123 includes a second motor mounted on the support plate 1111 and a second linear slide rail mounted on the support plate 1111. A second sliding plate is mounted on the second linear slide rail, and the second sliding plate is connected to the second motor via a lead screw drive. The first lateral movement unit 122 and the clamping unit 121 are mounted on the second sliding plate, thereby enabling the second motor to drive the lead screw to rotate, which in turn drives the first lateral movement unit 122 and the clamping unit 121 to move along the second direction. The first lateral movement unit 122 includes a first motor mounted on the second sliding plate and a first linear slide rail mounted on the second sliding plate. A first sliding plate is mounted on the first linear slide rail, and the first sliding plate is connected to the first motor via a lead screw drive. The clamping unit 121 is fixedly mounted on the first sliding plate, thereby enabling the first motor to drive the lead screw to rotate, which in turn drives the clamping unit 121 to move along the first direction.
[0040] It should be noted that the driving form of the first transverse unit 122 and the second transverse unit 123 is not limited to the driving form of the drive motor and the lead screw. As long as linear motion in the first direction and the second direction are achieved respectively, linear motor drive or cylinder drive can also be used in other possible embodiments. No specific limitation is made here.
[0041] like Figure 3 As shown, the gripping unit 121 includes two grippers 1211 that can move closer together or open apart, and a first drive cylinder that drives the two grippers 1211 to move. Each of the two grippers 1211 has a clamping groove 1212 on its opposite side, which at least partially conforms to the sidewall of the battery cell. The curved contour of the clamping groove 1212 fits tightly to the sidewall of the battery cell; for example, a cylindrical battery cell is matched with an arc-shaped clamping groove. This increases the contact area between the grippers 1211 and the battery cell, disperses the clamping pressure, and prevents damage to the surface coating or deformation of the internal structure of the battery cell. Simultaneously, the depth of the clamping groove 1212 can cover more than one-third of the height of the sidewall of the battery cell, forming a mechanical limiting structure. Under high-speed transport or vibration conditions, this greatly reduces the risk of the battery cell slipping out.
[0042] It should be noted that the number of clamping and correction mechanisms 12 on the support plate 1111 is not limited; one or more sets can be set according to actual needs. When multiple sets of clamping and correction mechanisms 12 are set, multiple battery cells can be clamped and transferred simultaneously. In this embodiment, four sets of clamping and correction mechanisms 12 are arranged in parallel.
[0043] It should be noted that the correctable battery cell feeding device 1 in this embodiment also includes a control system, and the relevant mechanical actions of the transfer mechanism 11 and the clamping and correcting mechanism 12 are all controlled by the control system. Example 2
[0044] This embodiment provides a battery cell assembly device, including the correctable battery cell feeding device 1 from Embodiment 1, and the housing insertion device 2 for loading the battery cells into the housing.
[0045] like Figure 4 As shown, the casing insertion device 2 includes a cell adsorption mechanism 21 for carrying the battery cell, a casing fixing mechanism 22 for positioning and fixing the casing, and a pushing mechanism 23 for pushing the battery cell into the casing. The casing fixing mechanism 22 and the pushing mechanism 23 are located on both sides of the cell adsorption mechanism 21 in the third direction. By aligning the cell adsorption mechanism 21 and the pushing mechanism 23 coaxially in the third direction, and cooperating with the positioning of the casing fixing mechanism 22, a linear motion trajectory for pushing the battery cell into the casing is achieved.
[0046] like Figure 4 and Figure 5 As shown, the corrective battery cell loading device 1 transfers the corrected battery cells to the battery cell adsorption mechanism 21. The battery cell adsorption mechanism 21 includes a battery cell placement platform 211 and a negative pressure unit (not shown in the figure). The battery cell placement platform 211 and the negative pressure unit correspond one-to-one with the battery cells transferred by the corrective battery cell loading device 1. The surface of the battery cell placement platform 211, which supports the battery cells, is provided with adsorption holes 2111 that communicate with the negative pressure unit. The surface of the battery cell placement platform 211, which supports the battery cells, has the same shape as the bottom of the battery cells. The negative pressure unit can use existing technology, such as a vacuum pump. The adsorption holes 2111 are arranged in an array on the surface of the battery cell placement platform 211. The negative pressure unit generates a uniform adsorption force, ensuring that the battery cells are evenly stressed and stably placed on the surface of the battery cell placement platform 211. The pushing mechanism 23 includes a punch 231 and a punch drive unit 232 for driving the punch 231 to move in a third direction. The cell placement platform 211 is provided with a punch hole 2112. The punch 231 can pass through the punch hole 2112 and abut against the cell, thereby pushing the cell into the housing. The punch 231 moves strictly along the axial direction (third direction) of the punch hole 2112 to form a mechanical limiting channel, ensuring that the pushing path coincides with the axis of the housing opening. The head of the punch 231 is designed with a soft material, which can fully fit against the end face of the cell, reducing the pressure of hard contact on a plane.
[0047] It should be noted that in this embodiment, the punch drive unit 232 adopts a cylinder drive form. Specifically, a slider is provided, which is slidably mounted on the frame via a linear slide rail. The punch 231 is fixed on the slider, and the output shaft of the cylinder is connected to the slider. The cylinder drives the slider to move in a third direction, thereby driving the punch 231 to move.
[0048] like Figure 6 As shown, the housing fixing mechanism 22 includes a housing placement platform 221 and a push rod 222 located on the side of the housing placement platform 221 opposite to the cell placement platform 211. The housing placement platform 221 has a through hole 2211 for accommodating the housing, directly opposite the cell placement platform 211. A fixing block 2212, which fits against the side wall of the housing, is provided on the edge of the through hole 2211 near the push rod 222. The push rod 222 can move closer to or away from the fixing block 2212 to clamp or release the housing. The side wall of the fixing block 2212 fits tightly against the contour of the housing side wall. The push rod 222 moves closer to or away from the fixing block 2212 along a straight line. The fixing block 2212 and the push rod 222 constitute a housing clamping assembly, which, compared to traditional planar clamps, increases the contact area, disperses clamping stress, and avoids localized deformation of the housing. Furthermore, the number of fixing blocks 2212 can be one or two, or other numbers may be used. When one fixing block 2212 is provided, it is opposite to the push rod 222; when two fixing blocks 2212 are provided, the two fixing blocks 2212 are symmetrically distributed, and the center point of the contact surface between the two fixing blocks 2212 and the side wall of the housing and the center point of the contact surface between the push rod 222 and the side wall of the housing form an isosceles triangle.
[0049] It should be noted that the push rod 222 is slidably mounted on the housing platform 221 via a linear slide rail, and is driven by a cylinder to move along the first direction. The push rod 222 can be designed in various ways, such as... Figure 6 As shown, the push rod 222 adopts an integral design, meaning that multiple housings share a single push rod 222 for fixation. The push rod 222 has an abutment surface whose length covers all housings, or the push rod 222 is provided with abutment blocks corresponding to each housing. The cylinder drives the push rod 222 to move, and the abutment surface or abutment block of the push rod 222 can contact all housings, thereby forming a clamping assembly with the fixing block 2212 corresponding to each housing to fix the housing. Alternatively, the push rod 222 can also adopt a split design, meaning that each housing corresponds to an independent push rod 222 and cylinder.
[0050] It should be noted that the through hole 2211 is not directly set on the body of the housing placement platform 221. A detachable mold plate can be set there. The through hole 2211 and the fixing block 2212 are set on the mold plate. By replacing the mold plate with different through hole diameters 2211, it is possible to achieve compatibility with housings of different sizes.
[0051] The housing fixing mechanism 22 also includes two guide clamps 223 located on the side of the housing placement platform 221 opposite to the push rod 222, which can move closer together or open. Guide grooves are formed on opposite sides of the two guide clamps 223, and the two guide grooves move closer together to form a guide hole, which coincides with the axis of the housing. When the guide clamps 223 are closed, the guide hole formed is strictly coincident with the axis of the housing. The orifice of the guide hole can be designed as a tapered guide section. During the process of pushing the battery cell into the housing, even if there is a slight initial position deviation of the battery cell, the mechanical constraint of the guide hole sidewall can automatically correct the deviation angle, avoiding hard scraping between the edge of the housing opening and the sidewall of the battery cell, thus preventing scratches to the battery cell. Furthermore, the openable / closable design of the guide clamps 223 allows for adjustment of the clamping spacing, accommodating battery housings of various diameters and flexibly adapting to different housing sizes. In this embodiment, the two guide clamps 223 are opened and closed by a second drive cylinder.
[0052] It should be noted that the cell assembly equipment in this embodiment is suitable for housings of different shapes, including cylindrical and prismatic housings. Furthermore, by adjusting the program or changing the mold, it can also be applied to housings of different sizes.
[0053] It should be noted that the battery cell assembly equipment in this embodiment also includes a control system, and the relevant mechanical actions of the corrective battery cell feeding device 1 and the casing device are all controlled by the control system.
