Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery casing positioning device. Background Technology

[0002] In the existing battery module production process, the aluminum casing is an important protective shell for the battery module. Positioning the aluminum casing can ensure that each battery is in the correct position in the module. This allows the battery module to form a compact and stable whole in the subsequent packaging process.

[0003] Currently, the positioning of the aluminum shell in the battery module during the production process mainly relies on manual intervention, which is inefficient and not precise enough. This affects subsequent processing operations, making it difficult to guarantee the accuracy and consistency of the battery module, potentially resulting in many defective products and reducing product quality. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a battery case positioning device, which transfers the battery case to the positioning seat through a transfer component and automatically and accurately positions the battery case through a positioning component, so that the battery case can be placed completely and correctly on the platform, which facilitates the subsequent series of operations of the mechanism. The structure is automated, which can effectively reduce the defect rate and improve product quality.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A battery casing positioning device, comprising:

[0007] A positioning assembly includes a positioning frame, a positioning seat, and a positioning seat drive. The positioning seat is mounted on the positioning frame and is movable along the Z-axis. The positioning seat is provided with at least two sets of positioning elements, each of which includes a movable clamping plate, a fixed clamping plate, and a movable clamping plate drive. The movable clamping plate and the fixed clamping plate are spaced apart to form a clamping gap. The movable clamping plate drive is used to drive the movable clamping plate to move. The positioning seat drive is used to drive the positioning seat to move along the Z-axis.

[0008] A transfer assembly for gripping a workpiece and transferring it to the clamping interval.

[0009] Furthermore, the positioning seat is provided with a slide rail, which is located within the clamping interval and extends along the Y-axis. Both ends of the slide rail are also provided with buffers. The movable clamping plate is provided with a slider at one end near the slide rail. The slider is located between the two buffers and slides with the slide rail to abut against the two buffers respectively.

[0010] Furthermore, both the movable clamping plate and the fixed clamping plate are provided with a first buffer at one end facing the clamping interval, and the first buffer abuts against the workpiece.

[0011] Furthermore, the movable clamping plate driving component includes a driving cylinder and a piston rod. The driving cylinder is connected to the piston rod to drive the piston rod to move closer to or away from the movable clamping plate, so that the movable clamping plate moves closer to or away from the fixed clamping plate along the Y-axis direction.

[0012] Furthermore, a pressing block is provided at one end of the piston rod near the movable clamping plate. The pressing block moves closer to or away from the movable clamping plate with the piston rod and can press against the movable clamping plate when moving closer to it. A second buffer is provided at one end of the pressing block near the movable clamping plate. The second buffer is used to abut against the movable clamping plate after the pressing block approaches it.

[0013] Furthermore, the transfer assembly includes a transfer frame, a transfer seat, a clamping member, and a transfer seat drive member. The transfer seat is movably connected to the transfer frame, and the transfer seat drive member is used to drive the transfer seat to move closer to or away from the clamping interval and to move along the Z-axis direction. The clamping member is installed on the bottom of the transfer seat.

[0014] Furthermore, it also includes at least two sets of rotating components, each including a turntable, a rotating shaft, and a turntable drive. The turntable drive is mounted on the transfer seat and connected to the rotating shaft to drive the rotating shaft to rotate. The other end of the rotating shaft is connected to the turntable and is used to drive the turntable to rotate during rotation. The bottom of the turntable is provided with multiple suction cups, which are the clamping components for clamping workpieces. The turntable is used to drive the workpiece to rotate during rotation.

[0015] Furthermore, the rotating shaft is a telescopic rotating shaft, and is used to extend and retract during rotation so that the turntable can move closer to or further away from the clamping interval.

[0016] Furthermore, a baffle is provided within the clamping interval, and a push plate and a push plate drive are provided on the turntable. The push plate is used to rotate with the turntable after the turntable moves close to the clamping interval, and is arranged opposite to the baffle to move closer to or away from the baffle. The push plate drive is connected to the push plate to drive the push plate to move closer to or away from the baffle.

[0017] Furthermore, an elastic component is provided between the baffle and the positioning seat, and the elastic component abuts against the end of the baffle that is away from the clamping interval.

[0018] In summary, the battery casing positioning device provided by this utility model has the following technical effects: In specific use, the battery casing is clamped by the transfer component and transferred to the clamping interval on the positioning seat. At this time, the movable clamping plate drive component drives the movable clamping plate to move towards the fixed clamping plate to clamp the battery casing. Then, the positioning seat drive component drives the positioning seat to move along the Z-axis direction to transport the battery casing to the next processing station. Since the battery casing is always clamped during transportation, it is not easy to shake, which allows it to be accurately transported to the next processing platform. This helps the battery casing to cooperate precisely with other processing components, effectively reducing the defect rate in the production process, improving product quality, and making the structure more automated, thus indirectly improving production efficiency.

[0025] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] See Figures 1 to 4 This utility model discloses a battery casing positioning device, including a positioning component and a transfer component. The positioning component includes a positioning frame 10, a positioning seat 11, and a positioning seat drive 19. The positioning seat 11 is installed on the positioning frame 10 and driven by the positioning drive 19 to move along the Z-axis. At least two sets of positioning components are provided on the positioning seat 11. The positioning components include a movable clamping plate 14, a fixed clamping plate 13, and a movable clamping plate drive 15. The movable clamping plate 14 and the fixed clamping plate 13 are spaced apart to form a clamping interval 12. The movable clamping plate drive 15 is used to drive the movable clamping plate 14 to move. The transfer component is used to clamp the workpiece and transfer it to the clamping interval 12.

[0029] Based on the above structure, in practical use, the workpiece (such as a battery case or other parts that need to be positioned) can first be clamped by the transfer component and transferred to the clamping interval 12. At this time, the movable clamping plate drive component 15 starts to operate, driving the movable clamping plate 14 along the Y-axis direction (e.g., ...). Figure 1 As shown, the positioning frame 10 moves closer to the fixed clamping plate 13 in the left-right direction until the movable clamping plate 14 comes into contact with the workpiece to clamp it. After that, the positioning seat drive 19 starts to operate, driving the positioning seat 11 along the Z-axis direction (as shown). Figure 1 As shown in the figure, the positioning frame 10 moves in the height direction to accurately transport the workpiece on the positioning seat 11 to the next processing platform to start the subsequent processing operation; after the workpiece is processed, the positioning seat 11 and the movable clamping plate 14 are reset again by the positioning seat drive 19 and the movable clamping plate drive 15 to start the next round of cycle operation.

[0030] Specifically, during the battery module production process, if the battery casing (such as a square aluminum casing) is not clamped during transport, it may shake or collide during transport, resulting in scratches or deformation on the surface of the battery casing and a high defect rate. Therefore, when the battery casing positioning device in this embodiment is applied to the battery module production line, since the battery casing is always clamped by the movable clamping plate 14 and the fixed clamping plate 13, the battery casing is not easily damaged by shaking or collision during transport. It can also ensure that the battery casing can be accurately transported to the next processing platform, which helps the battery casing to cooperate precisely with other processing components, effectively reducing the defect rate in the production process, improving product quality, and making the structure more automated, thus indirectly improving production efficiency.

[0031] It should be noted that the transfer component in this embodiment can be an existing robotic arm that directly grips or grasps the workpiece to transport it into the clamping interval 12. Of course, in another embodiment, the transfer component can also be a drive mechanism and a structure for gripping the workpiece (such as a gripper or suction cup 42, etc.) that drives the structure for gripping the workpiece to move closer to the clamping interval 12 through a linear motor set or by a combination of a drive motor and a transmission structure to transfer the workpiece.

[0032] More specifically, the positioning seat drive 19 in this embodiment can be a linear motor module. By connecting the positioning seat 11 to the guide rail in the linear motor module, the positioning seat 11 can be driven to move up and down in the Z-axis direction. Of course, the positioning seat 11 can also be connected to a transmission device, such as a synchronous belt and a gear, and then the motor drives the gear and the synchronous belt to move up and down in the Z-axis direction. Alternatively, the positioning seat 11 can be slidably connected to the positioning frame 10, and the above effect can also be achieved by directly driving the positioning seat 11 to slide through the motor. The specific setting can be determined according to actual needs.

[0033] In addition, the movable clamping plate drive component 15 can be driven by a drive motor or a drive cylinder 151. During assembly, the drive motor is electrically connected to the movable clamping plate 14 to directly drive the movable clamping plate 14 to move linearly. When the movable clamping plate drive component 15 is a drive cylinder 151, the piston rod 152 of the drive cylinder 151 can be set toward the movable clamping plate 14, so that when the drive cylinder 151 drives the piston rod 152 to move, it can push the movable clamping plate 14 to move closer to or away from the fixed clamping plate 13, so as to achieve the effect of clamping or releasing the workpiece.

[0034] More specifically, since the positioning components are provided in at least two sets, the transfer assembly can simultaneously clamp at least two workpieces to at least two clamping intervals 12, thereby simultaneously clamping and positioning at least two workpieces and accurately transporting them to the next processing platform, thus improving production efficiency.

[0035] It should be noted that the positioning components can be set to two, three, or more sets according to actual production needs.

[0036] Furthermore, a slide rail 18 is provided on the positioning seat 11. The slide rail 18 is located within the clamping interval 12 and extends along the Y-axis. Buffers 181 are also provided at both ends of the slide rail 18. A slider 141 is provided at one end of the movable clamping plate 14 near the slide rail 18. The slider 141 is located between the two buffers 181 and slides with the slide rail 18 to abut against the two buffers 181 respectively.

[0037] Based on this structure, in this embodiment, by setting a slider 141 on the movable clamping plate 14 to slide in cooperation with the slide rail 18 on the positioning seat 11, the movable driving component can drive the movable clamping plate 14 to move more smoothly and is less prone to jamming.

[0038] In addition, if there is no buffer structure, when the slider 141 slides to both ends of the slide rail 18, the slider 141 is prone to violent collision with the ends of the slide rail 18, which may cause damage to the slider 141 and the slide rail 18, such as deformation of the slider 141 and wear of the ends of the slide rail 18. Therefore, in this embodiment, buffers 181 are provided at both ends of the slide rail 18. The buffers 181 can absorb the kinetic energy of the slider 141, making the collision process gentler and greatly reducing the impact force, thereby extending the service life of the slider 141 and the slide rail 18.

[0039] Specifically, by setting buffers 181 at both ends of the slide rail 18, when the buffer 181 on the outer side of the slider 141 on the movable clamping plate 14 moves to the buffer 181 near the fixed clamping plate 13, the buffer 181 on the inner side can also limit the slider 141, so that the movable clamping plate 14 no longer moves, thus indicating to the operator that the workpiece has been fully pushed and tightened by the movable clamping plate 14, making the structure more practical.

[0040] It should be noted that the buffer 181 in this embodiment can be an existing hydraulic buffer 181, spring buffer 181 or rubber buffer 181. Compared with directly setting elastic components 17 (such as springs or elastic columns) at both ends of the slide rail 18, the buffer 181 can provide a more uniform buffering force, keep relatively stable throughout the entire buffering stroke, and effectively avoid the impact on the equipment caused by sudden changes in buffering force.

[0041] More specifically, a first buffer is provided at the end of the movable clamping plate 14 and the fixed clamping plate 13 facing the clamping interval 12. The first buffer can be a buffer pad made of rubber, silicone or urethane, etc., which has elasticity and is bonded to the movable clamping plate 14 and the fixed clamping plate 13. In this way, when the workpiece is clamped by the movable clamping plate 14 and the fixed clamping plate 13, the first buffer can generate elastic deformation through its own elasticity to effectively buffer the clamping force on the surface of the workpiece and reduce the risk of damage to the surface of the workpiece.

[0042] In addition, when the workpiece is clamped, the presence of the first buffer can adjust the friction between the workpiece and the movable clamping plate 14 and the fixed clamping plate 13 to a certain extent, preventing the workpiece from shifting during processing and making the structure more stable.

[0043] Furthermore, the movable clamping plate drive component 15 includes a drive cylinder 151 and a piston rod 152. The drive cylinder 151 is connected to the piston rod 152 to drive the piston rod 152 to move closer to or away from the movable clamping plate 14, so that the movable clamping plate 14 moves closer to or away from the fixed clamping plate 13 along the Y-axis direction.

[0044] Specifically, after the workpiece is transferred to the clamping interval 12, the drive cylinder 151 drives the piston rod 152 to extend and push the movable clamping plate 14 to move close to the workpiece until it touches the workpiece, so that the workpiece is clamped. After the processing operation is completed, the drive cylinder 151 drives the piston rod 152 to retract again, so that the interval of the clamping interval 12 is increased, and the next round of clamping action begins.

[0045] Compared to directly driving the movable clamping plate 14 using a linear motor or drive motor, this embodiment uses a drive cylinder 151 and piston rod 152 to drive the movable clamping plate 14. This eliminates the need for complex electronic components and control systems, resulting in a simpler structure and easier maintenance. Furthermore, the drive cylinder 151 provides greater output force than a drive motor, easily moving heavier clamping plates and workpieces on them. This results in a greater clamping force on the movable clamping plate 14 when it pushes the workpiece to clamp it, making the workpiece more stable and less prone to loosening after clamping.

[0046] Furthermore, a pressing block 153 is provided at one end of the piston rod 152 near the movable clamping plate 14. The pressing block 153 moves closer to or further away from the movable clamping plate 14 with the piston rod 152, and presses against the movable clamping plate 14 when it moves closer to the movable clamping plate 14. A second buffer is provided at one end of the pressing block 153 near the movable clamping plate 14. The second buffer is used to abut against the movable clamping plate 14 after the pressing block 153 approaches the movable clamping plate 14.

[0047] Specifically, during the pressing process, if a large pressure is concentrated in a small contact area, it can easily cause local damage to the surface of the movable clamping plate 14. Therefore, in this embodiment, a pressing block 153 is provided at one end of the piston rod 152 near the movable clamping plate 14 to increase the contact area between the end of the piston rod 152 and the movable clamping plate 14, so that the pressing stress is more evenly distributed on the clamping plate and the risk of local damage is reduced.

[0048] More specifically, since the top pressure block 153 is provided with a second buffer at one end near the movable clamping plate 14, the second buffer can also be a buffer pad made of rubber, silicone or urethane, etc., which has elasticity and is bonded to the top pressure block 153. In this way, when the top pressure block 153 approaches the movable clamping plate 14 and comes into contact with it, the second buffer can generate elastic deformation through its own elasticity to effectively buffer the top pressure on the surface of the movable clamping plate 14 and reduce the risk of damage to the surface of the movable clamping plate 14.

[0049] Furthermore, the transfer assembly includes a transfer frame 20, a transfer seat 30, a clamping member, and a transfer seat drive member 31. The transfer seat 30 is movably connected to the transfer frame 20. The transfer seat drive member 31 is used to drive the transfer seat 30 to move closer to or further away from the clamping interval 12 and to move along the Z-axis direction. The clamping member is installed at the bottom of the transfer seat 30.

[0050] Based on this structure, during assembly, the transfer frame 20 can be extended toward the positioning component. Specifically, the extension direction of the positioning frame 10 can be the aforementioned Y-axis direction. A slide rail 18 or guide rail is provided on the transfer frame 20. The transfer seat 30 is movably connected to the slide rail 18 or guide rail of the transfer frame 20 through a connecting structure (such as a connecting plate, connecting block, or connecting seat), so that the connecting structure can move back and forth along the Y-axis direction to drive the transfer seat 30 to move. In addition, since the transfer seat 30 also needs to move up and down in the Z-axis direction, during specific installation, the connecting structure used to install the transfer seat 30 is extended along the Z-axis direction, and a slide rail 18 or guide rail is provided on the connecting structure, so that the transfer seat 30 is movably connected to the transfer seat 30. The transfer seat drive component 31 consists of two drive motors. One drive motor is used to drive the connecting structure to move along the Y-axis direction, so as to drive the transfer seat 30 to move closer to or away from the clamping interval 12 along the Y-axis direction. The other drive motor is used to drive the transfer seat 30 to move up and down along the Z-axis direction.

[0051] Of course, in another implementation, the above effect can also be achieved by setting a transmission mechanism (such as a synchronous belt, transmission gear, etc.) on the transfer frame 20, connecting the drive motor to the transmission gear to drive the synchronous belt to move, and then connecting the transfer seat 30 to the synchronous belt through a connecting structure to drive the transfer seat 30 to move. In addition, the transfer seat 30 can also include two sets of linear motor modules, and the transfer seat 30 can be driven to move in two directions by the two sets of linear motor modules. The specific configuration can be set according to actual needs.

[0052] In practical use, when it is necessary to transfer the workpiece, the transfer seat 30 is moved downward along the Z-axis until the clamping member picks up the workpiece. Then, the transfer seat 30 is moved along the Y-axis closer to the clamping interval 12 until it is above the clamping interval 12. At this time, the transfer seat 30 is moved downward along the Z-axis again so that the workpiece falls into the clamping interval 12. Finally, the workpiece is clamped by the positioning member, and the processing operation begins. After the workpiece is clamped, the transfer seat 30 can be reset and a new cycle of operation can begin.

[0053] It should be noted that the gripping component in this embodiment can use a vacuum suction cup, a gripper, or other structures to grip the workpiece.

[0054] Furthermore, it also includes at least two sets of rotating components. The rotating components include a turntable 40, a rotating shaft 45, and a turntable drive 41. The turntable drive 41 is mounted on the transfer seat 30 and connected to the rotating shaft 45 to drive the rotating shaft 45 to rotate. The other end of the rotating shaft 45 is connected to the turntable 40 and drives the turntable 40 to rotate when rotating. The bottom of the turntable 40 is provided with multiple suction cups 42, which are clamping components to clamp the workpiece. The turntable 40 drives the workpiece to rotate when rotating.

[0055] Specifically, since the workpiece needs to be adjusted in angle during processing, especially when applied to a square aluminum shell processing line, the aluminum shell needs to be aligned during processing to ensure precise alignment with other components in the next processing position. Therefore, this embodiment sets at least two sets of rotating components. In actual use, multiple suction cups 42 at the bottom of the turntable 40, specifically existing vacuum suction cups 42, are used in conjunction with external air pipes to achieve negative pressure adsorption, reducing damage to the workpiece. During transportation, the workpiece is first adsorbed by the suction cups 42, and then the transfer seat 30 is moved above the positioning seat 11, so that at least two turntables 40 are respectively located above the two clamping intervals 12. At this time, the turntable drive 41 drives the turntable 40 to rotate and rotates the workpiece to be aligned, so that the workpiece falls into the clamping interval 12 and is in the correct position to adapt to precise assembly with other components, making the structure more practical.

[0056] It should be noted that the number of rotating components in this embodiment corresponds to the number of positioning components. Specifically, there can be two, three, or more sets, depending on the actual needs.

[0057] More specifically, the rotating shaft 45 is a telescopic rotating shaft 45, which extends and retracts during rotation, allowing the turntable 40 to move closer to or further away from the clamping interval 12. Thus, when the battery case is transferred above the clamping interval 12, it can first move downward along the Z-axis via the transfer seat 30 itself, bringing the battery case closer to the clamping interval 12. If the position of the battery case is not accurate enough and cannot fall completely into the clamping interval 12, the transfer seat 30 can be moved again along the Y-axis to fine-tune the position of the workpiece. After the position is accurately adjusted, the telescopic rotating shaft 45 is driven to rotate via the turntable drive 41. During the rotation, the turntable 40 straightens the angle of the workpiece and moves closer to the clamping interval 12 again, so as to assist the workpiece in moving up and down via the telescopic rotating shaft 45, making the workpiece more flexible in moving up and down in the Z-axis direction, and making it fall more accurately into the clamping interval 12 after straightening. After that, the suction force of the suction cup 42 decreases, the workpiece falls completely into the clamping interval 12, the transfer assembly and the rotating assembly reset, and the next cycle begins.

[0058] Furthermore, a baffle 16 is provided within the clamping interval 12, and a push plate 43 and a push plate drive member 44 are provided on the turntable 40. The push plate 43 is used to rotate with the turntable 40 after the turntable 40 moves close to the clamping interval 12, and is arranged opposite to the baffle 16 to move closer to or away from the baffle 16. The push plate drive member 44 is connected to the push plate 43 to drive the push plate 43 to move closer to or away from the baffle 16.

[0059] Specifically, after the workpiece is picked up by the suction cup 42 and transported to the clamping interval 12, there will be some deviation in the front-back, left-right and right directions. In order to facilitate the accurate cooperation of the workpiece with other components after it is transported to the next processing platform, it is necessary to straighten the workpiece in all directions. Therefore, in this embodiment, a baffle 16 is also provided in the clamping interval 12. The baffle 16 can be aligned along the X-axis direction (e.g., ...). Figure 1 As shown, the movable clamping plate 14 is positioned in the front-to-back direction of the workpiece. When the workpiece falls into the clamping interval 12, the movable clamping plate 14 moves along the Y-axis towards the fixed clamping plate 13, clamping the workpiece left and right. As the turntable 40 rotates, it drives the workpiece to be aligned, and at the same time, the push plate 43 can be aligned relative to the baffle 16 (see reference). Figure 3 At this time, the push plate 43 can be driven by the push plate drive 44 to move in the X-axis direction to push the workpiece to abut against the baffle 16, so as to straighten the front and back direction of the workpiece. In this way, the front, back and left and right directions of the workpiece are straightened, so that it can more accurately cooperate with the components of the next processing platform.

[0060] It should be noted that in this embodiment, the push plate drive component 44 can also be an existing drive cylinder 151. During assembly, the piston rod 152 is connected to the push plate 43 to drive the push plate 43 to move closer to or away from the baffle 16 along the X-axis direction.

[0061] More specifically, an elastic component 17 is provided between the baffle 16 and the positioning seat 11. The elastic component 17 abuts against the end of the baffle 16 away from the clamping interval 12. In this way, when the workpiece abuts against the baffle 16, the elastic component 17 behind the baffle 16 can absorb and disperse the impact force, thereby effectively reducing the impact of the pusher 43 on the surface of the workpiece and reducing the risk of the workpiece surface being damaged during the positioning process.

[0062] Meanwhile, when the pusher plate 43 pushes the workpiece closer to the baffle 16, the elastic component 17 can provide a uniform reaction force. Depending on the contact between the workpiece and the baffle 16, it will generate corresponding elastic force at different positions. If the position of the workpiece is slightly tilted, the elastic force at different points of contact with the baffle 16 will be different. For example, if one side of the workpiece contacts the baffle 16 first, the elastic component 17 on that side will be compressed, generating an elastic force. This elastic force will push that side of the workpiece, causing it to tend to correct its movement. At this time, the elastic component 17 on the other side of the workpiece has not been fully compressed, so its elastic force is relatively small. This will create a force difference, causing the battery case to rotate to the correct position, thereby achieving alignment, so as to assist the workpiece through the elastic component 17.

[0063] It should be noted that the elastic component 17 can be an existing spring, elastic rod, or elastic pad (such as a rubber pad or silicone pad); of course, the above effect can also be achieved by setting an elastic pad at one end of the baffle 16 near the clamping interval 12.

[0064] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
