Description

Technical Field

[0001] This utility model relates to the field of negative electrode cover feeding technology, specifically to a feeding device. Background Technology

[0002] On automated production and assembly lines for batteries (especially cylindrical lithium batteries), the loading and precise positioning of the negative electrode cap is a critical process. Traditional loading devices typically use vibratory feeders, conveyor belts, or chain conveyors for transport.

[0003] For example, patent publication number CN114590551A discloses a conveyor device for battery production transportation with adjustable conveying angle. This device aims to solve the problem of matching the conveying distance and angle through the design of an adjustable conveyor belt and pulleys. Multiple protrusions evenly arranged on the first conveyor belt can be used for the initial positioning of objects.

[0004] However, these general-purpose transmission devices still have significant shortcomings when applied to specific, precision components such as negative electrode caps. The protrusions on their transmission belts are usually fixed and non-removable. When the production line needs to change to a different model of negative electrode cap, the entire transmission belt or the module with the fixed protrusions must be replaced. This process is cumbersome and time-consuming, resulting in low equipment changeover efficiency and failing to meet the rapid response requirements of flexible manufacturing. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a feeding device to solve the technical problems of low equipment changeover efficiency and inability to meet the rapid response requirements of flexible manufacturing in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a feeding device, including a frame, at least two sets of transmission wheels, a conveying component, several blocking components, several locking structures, and a driving component; at least two sets of transmission wheels are arranged side by side on the frame; the conveying component is sleeved on the at least two sets of transmission wheels and can circulate between the at least two sets of transmission wheels as the transmission wheels rotate; several blocking components are sequentially and spaced apart on the surface of the conveying component along the conveying direction; several locking structures connect several blocking components and the conveying component so that the blocking components are detachably connected to the conveying component; the driving component is connected to one set of transmission wheels and is used to drive the transmission wheels to rotate.

[0007] In some embodiments, the surface of the conveying member is provided with a plurality of slots in sequence along its conveying direction, one end of the locking structure is connected to the blocking member, and the other end extends into the slot to form a clamping or snapping engagement with the slot.

[0008] In some embodiments, a plurality of the locking structures are respectively disposed on both sides of the two ends of the blocking member.

[0009] In some embodiments, the locking structure includes two clamping members and a locking member. One end of each of the two clamping members is rotatably connected to the blocking member, and the other end forms a clamping end for extending into the slot. The locking member is connected to the two clamping members and is used to generate a locking force that drives the clamping ends of the two clamping members to move closer to each other to clamp the two slot sidewalls.

[0010] In some embodiments, the locking element includes a screw that passes through both clamping elements and is threaded to bring the clamping ends of the two clamping elements closer together or further apart.

[0011] In some embodiments, the locking element includes a spring disposed between the two clamping elements for providing an elastic force that brings the clamping ends of the two clamping elements closer together.

[0012] In some embodiments, at least one groove wall of the slot is constructed with a concave or convex portion or a toothed portion, and the clamping end of the locking structure has a mating surface that engages with the concave or convex portion or the toothed portion.

[0013] In some embodiments, the feeding device further includes a protective cover that covers the outside of the clamping structure.

[0014] In some embodiments, the conveyor is a conveyor chain.

[0015] In some embodiments, the driving component includes a drive motor, a plurality of rotating shafts and a plurality of gears. The plurality of rotating shafts are rotatably mounted on the frame. The output end of the drive motor is connected to the rotating shafts to drive them to rotate. The gears are fixedly mounted on the rotating shafts and mesh with the conveyor chain plate to drive the conveyor chain plate to move cyclically as the rotating shafts rotate.

[0016] Compared with existing technologies, the feeding device provided by this utility model, by setting up a number of blocking components spaced apart along the surface of the conveyor, can physically limit the negative electrode cap during the conveying process, preventing it from shifting or tipping due to inertia or vibration. This provides precise positioning and ensures orderly conveying. Furthermore, a detachable locking structure connecting the blocking components to the conveyor allows operators to adjust the fixed position of each blocking component on the conveyor, flexibly changing the spacing between adjacent blocking components. This achieves flexible adjustment of the blocking spacing to accommodate negative electrode caps of different sizes, ultimately achieving the core effect of multi-purpose operation and rapid changeover. In addition, this device has advantages such as simple structure, convenient operation, and high stability, meeting the rapid response requirements of flexible manufacturing and improving the automation level and production efficiency of battery production lines.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problems of low equipment changeover efficiency and inability to meet the rapid response requirements of flexible manufacturing, this utility model provides a feeding device that can easily adjust the fixed positions of each blocking component on the conveyor, thereby flexibly changing the interval between adjacent blocking components to adapt to negative electrode covers of different specifications and sizes. This enhances the flexibility and versatility of the device, enabling it to meet the rapid response requirements of flexible manufacturing.

[0021] It should be noted that the feeding device described in this utility model is used for, but not limited to, feeding and conveying negative electrode caps. For ease of explanation, this utility model only uses the feeding device applied to feeding and conveying negative electrode caps as an example. The principle of the feeding device applied to the conveying of other types of parts is essentially the same as that applied to feeding and conveying negative electrode caps, and will not be described in detail here.

[0022] Please see Figures 1 to 7 , Figure 1 This is a schematic diagram of the feeding device in one embodiment of the present invention. The feeding device includes a frame 1, at least two sets of transmission wheels 2, a conveying component 3, several blocking components 4, several locking structures 5, and a driving component 6. At least two sets of transmission wheels 2 are arranged side by side on the frame 1. The conveying component 3 is sleeved on the at least two sets of transmission wheels 2 and can move cyclically between the at least two sets of transmission wheels 2 as the transmission wheels 2 rotate. Several blocking components 4 are arranged sequentially and at intervals on the surface of the conveying component 3 along the conveying direction of the conveying component 3. Several locking structures 5 connect several blocking components 4 and the conveying component 3 so that the blocking components 4 and the conveying component 3 are detachably connected. The driving component 6 is connected to one set of transmission wheels 2 and is used to drive the transmission wheels to rotate.

[0023] In this device, the drive unit 6 can drive the connected transmission wheel 2 to rotate. Since the conveyor 3 is sleeved between at least two sets of transmission wheels 2, the rotation of the transmission wheels 2 will drive the conveyor 3 to move accordingly, thereby driving the other transmission wheels 2 to rotate. This allows the conveyor 3 to circulate between at least two sets of transmission wheels 2, completing the material conveying task. Several blocking elements 4 set on the surface of the conveyor 3 can effectively prevent material from slipping during conveying, ensuring that the material moves stably with the conveyor 3. Since the blocking elements 4 are detachably connected to the conveyor 3 through the locking structure 5, when it is necessary to change the negative electrode cover model, simply remove the original blocking element 4 from the conveyor 3 and install a blocking element 4 that matches the new model of negative electrode cover. There is no need to replace the entire conveyor belt or the module with the fixed protrusion, thus greatly improving the efficiency of equipment changeover.

[0024] To improve the ease and accuracy of adjusting the position of the stopper 4, please refer to... Figures 1 to 3 In some possible embodiments, the surface of the conveying member 3 is provided with a plurality of slots 32 sequentially along its conveying direction, and a plurality of locking structures 5 are respectively arranged on both sides of the two ends of the blocking member 4, and intermittently arranged in the middle position on both sides of the blocking member 4, which can cooperate with the slots 32 on the surface of the conveying member 3. Specifically, the locking structure 5 includes two clamping members 51 and a locking member 52. One end of each of the two clamping members 51 is rotatably connected to the blocking member 4, and the other end forms a clamping end for extending into the slot 32. The locking member 52 is connected to the two clamping members 51. When the locking member 52 is operated, the locking member 52 can drive the clamping ends of the two clamping members 51 to move closer to each other, thereby clamping them firmly on the two side walls of the slot 32 like pliers, achieving a stable fixation.

[0025] Preferably, in this embodiment, the clamping member 51 is a gripper 511, and the blocking member 4 is a baffle 41, with several side plates 42 perpendicular to each other on both sides of the baffle 41. One end of two grippers 511 in a set is rotatably connected to one side plate 42, and the other end forms a clamping end that extends into the slot 32.

[0026] In this structure, the feed end of the frame 1 is equipped with an integrated feed hopper 8. At the same time, brackets 7 are installed at both ends of the frame 1, which connect the frame 1 and the opposite ends of the feed hopper 8, and play a role in providing stable support for the feed hopper 8.

[0027] To further simplify operation and ensure the reliability of locking, please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4 In one possible embodiment, the locking member 52 may be a screw 521. Specifically, one end of the screw 521 is threadedly connected to a clamping member 51, and the other end is threadedly connected to a slider 512 movably disposed on another clamping member 51, passing through both clamping members 51. The slider 512 achieves a sliding connection through a groove 513 opened on one side of the jaw 511, and can rotate relative to the groove 513 to adapt to the angular changes generated by the screw 521 during rotation. When the screw 521 is tightened, the wedging effect of the thread forces the clamping ends of the two clamping members 51 to come close to each other to clamp the slot 32; when loosened, the clamping ends separate, facilitating disassembly and movement.

[0028] As an alternative to screw 521 locking that enables quick operation and automatic reset, please refer to [link to relevant documentation]. Figure 1 , Figure 3 and Figure 5In another possible embodiment, the locking element 52 is a spring 522 disposed between the two clamping elements 51. The spring 522 continuously applies an elastic force, causing the clamping ends of the two clamping elements 51 to always tend to move closer to each other and clamp within the slot 32. This allows the operator to overcome the force of the spring 522 to separate the clamping ends 514 for position adjustment with just a simple wrench or by hand. After release, they will automatically clamp again, making it suitable for occasions requiring frequent fine adjustments.

[0029] Of course, in other possible embodiments, the locking member 52 and the clamping member 51 can also adopt other structural forms. For example, the locking member 52 adopts a magnetic structure, with magnets of opposite magnetic properties set at corresponding positions of the two clamping members 51. The magnetic force is used to bring the clamping ends of the two clamping members 51 closer to each other and clamp them in the slot 32. When the position needs to be adjusted, a certain external force is applied to overcome the magnetic force to separate the clamping ends 514. After the adjustment is completed, the clamping ends are released and can automatically clamp again under the action of magnetic force. Alternatively, the clamping member 51 is made of elastic plastic material, which has a certain elastic deformation capability. When the blocking member 4 and the conveying member 3 are installed, the clamping ends of the clamping members 51 are directly opened and inserted into the slot 32. The elasticity of the plastic is used to clamp the clamping ends to the side wall of the slot 32. When disassembling, the clamping ends can be opened again.

[0030] To significantly enhance the vibration resistance of the fixed structure and ensure that the blocking component 4 does not shift during long-term high-speed operation, please refer to [the relevant documentation]. Figure 1 , Figures 3 to 6 In some possible embodiments, the contact surface between the slot 32 and the clamping end is designed to prevent slippage. Specifically, a concave-convex portion is machined on the side wall of the slot 32, and its cross-sectional area gradually decreases from the outer periphery of the conveying member 3 towards the center. At the same time, a mating surface that can engage with it is also machined on the clamping end of the clamping structure 5. When the clamping end is clamped, the concave-convex portion and the mating surface interlock with each other, forming a mechanical interlock, thereby effectively resisting slippage caused by vibration.

[0031] Please see Figures 3 to 5 To protect the clamping structure 5 and prevent dust, material debris, or accidental collisions, the feeding device also includes a protective cover 53. The protective cover 53 can be installed around the clamping structure 5, providing effective dust protection and safety. Specifically, the protective cover 53 can be connected to the conveyor component 3 or the frame 1 via a plug-in or snap-fit ​​structure. This facilitates installation and disassembly, and allows for quick removal of the protective cover 53 for equipment maintenance and repair when needed. Furthermore, the protective cover 53 can be made of high-strength plastic or metal to meet the protection requirements of different working environments.

[0032] To ensure smooth conveying and load-bearing capacity, please refer to [link / reference]. Figures 1 to 7In some possible embodiments, the conveying component 3 can preferably be a conveyor chain plate 31, with chain holes on the conveyor chain plate 31 forming the aforementioned slots 32. This design not only allows the conveyor chain plate 31 to cooperate well with the drive wheel 2 for stable conveying, but also provides a stable mounting position for the locking structure 5 through the slots formed by the chain holes. Correspondingly, the driving component 6 can include a drive motor 61, a rotating shaft 62 driven by the motor, and multiple gears 63 fixed on the rotating shaft 62. Two sets of rotating shafts 62 are provided, arranged side by side at different heights. The gears 63 mesh with the conveyor chain plate 31, precisely driving the chain plate to move in a cycle.

[0033] Of course, in other possible embodiments, the conveyor 3 and the drive 6 can also adopt other structural forms. For example, the conveyor 3 can be a synchronous belt with raised toothed structures arranged at certain intervals. These toothed structures can act as slots 32, cooperating with the locking structure 5 to achieve a stable installation of the blocking member 4. The drive 6 can be a combination of a servo motor and a reducer.

[0034] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail as follows: When a specific model of negative electrode cover needs to be loaded, the drive unit 6 operates, driving the conveyor 3 to move cyclically. The negative electrode cover placed on the conveyor 3 is pushed or blocked within the gap formed by the blocking member 4 in front and moves forward. When it is necessary to change the model of the negative electrode cover, the operator only needs to loosen the locking member 52 of each clamping structure 5, so that the clamping end of the clamping member 51 is released from the current slot 32, then the entire blocking member 4 is moved to the target position, the clamping end is aligned and inserted into the corresponding slot 32, and finally the locking member 52 is tightened again.

[0035] This invention utilizes a plurality of blocking elements 4 spaced apart along the surface of the conveyor 3 to physically limit the negative electrode cap during transport, preventing it from shifting or tipping due to inertia or vibration. This ensures precise positioning and maintains transport order. Furthermore, a detachable locking structure 5 connects the blocking elements 4 to the conveyor 3, allowing operators to adjust the fixed positions of each blocking element 4 on the conveyor 3 and flexibly change the spacing between adjacent blocking elements 4. This achieves flexible adjustment of the blocking spacing to accommodate negative electrode caps of different sizes, ultimately enabling multi-purpose use and rapid changeover. In addition, this device features simple structure, convenient operation, and high stability, meeting the rapid response requirements of flexible manufacturing and improving the automation level and production efficiency of battery production lines.
