Description

Technical Field

[0001] This invention relates to an online vision-based integrated machine for assembling and riveting battery covers, belonging to the field of battery cover processing technology. Background Technology

[0002] In the field of power battery manufacturing, the assembly and riveting of battery cover plates is a key process to ensure the sealing performance of battery cells and the reliability of electrical connections. Currently, the industry generally uses rotary multi-station assembly and riveting equipment, which uses a rotating worktable to achieve continuous flow of processes such as loading, assembly, riveting, and unloading.

[0003] Existing equipment often uses methods such as independent cylinder direct push, swing arm gripping, or linear module transfer to deliver workpieces to the riveting station. This type of structure has three main drawbacks: First, the transfer process lacks an effective mechanical self-locking guiding mechanism; the workpiece and push rod only have point / line contact. Under high-speed cycles, this is easily affected by vibration, inertia, or fluctuations in the coefficient of friction, resulting in micro-displacement and causing deviations in the riveting point, leading to uneven crushing of the sealing ring, and poor connection of the pole piece, among other quality issues. Second, the coordination between the transfer mechanism and the turntable station heavily relies on photoelectric sensors or proximity switches for position determination. Metal debris and oil mist in the production environment easily adhere to the surface of the sensing elements, causing signal misinterpretation, action delays, or even mechanism collisions, resulting in a high rate of unplanned equipment downtime. Third, to improve positioning accuracy, existing solutions often require the superposition of multiple levels of guide rails, floating joints, or complex linkage mechanisms, leading to a bulky equipment structure, increased kinematic pairs, amplified cumulative errors, and complex maintenance and debugging, with single maintenance taking more than two hours, severely restricting the overall efficiency of the production line. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an online vision-based integrated battery cover assembly and riveting machine, aiming to resolve the prominent contradictions in existing battery cover assembly and riveting equipment regarding the reliability of mechanical positioning, the stability of coordinated mechanism movements, and the simplicity and ease of maintenance during the workpiece transfer process.

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

[0006] An online vision-based battery cover assembly and riveting machine includes a base frame and a chassis mounted on top of the base frame. The machine is characterized by: a riveting machine installed inside the chassis; a feeding device on one side of the riveting machine; the feeding device being connected to the base frame; and a self-locking mobile device between the riveting machine and the feeding device to eliminate battery cover transfer offset. This self-locking mobile device is connected to the base frame. The self-locking mobile device in this design physically eliminates the key issue of transfer offset, thereby replacing traditional cylinder pushing with mechanical self-locking, eliminating positioning gaps and dynamic shaking from the structural source, and ensuring stable feeding of the workpiece into the riveting area.

[0007] Preferably, the feeding device includes a columnar component mounted on top of the base frame. The columnar component contains a rotating mechanism, which is fixedly connected to the base frame. A turntable is mounted on the output shaft of the rotating mechanism, and at least two sets of feeding machines are mounted on the turntable. Each turntable and feeding machine has an opening at its corresponding location. In this design, the turntable and openings provide a vertical passage for the locking mechanism, ensuring precise coupling between the self-locking action and the turntable's rotation phase, thus avoiding mechanical interference. Multiple sets of feeding machines can support simultaneous feeding, conveying, and riveting operations, improving cycle time efficiency.

[0008] Preferably, the feeding machine includes a guide trough, in which a guide plate slides, and the top of the guide trough has a positioning post that restricts the backward sliding of the guide plate. In this design, the guide plate directly supports the battery cover assembly and serves as the execution carrier for the transfer action. The positioning post mechanically limits the guide plate to prevent it from sliding backward due to inertia when the turntable rotates, ensuring the stability of the initial positioning reference. The guide trough provides a horizontal guide track for the transfer process, constraining the movement trajectory of the guide plate.

[0009] Preferably, the self-locking mobile device includes a mobile unit, a lift mounted on top of the mobile unit, and a locking component mounted on the lift. The mobile unit is located inside the base frame and connected to the base frame. Above the locking component are multiple locking components, which are respectively mounted on multiple guide plates. In this solution, the self-locking mobile device completely replaces the traditional push rod contact transfer, achieving zero-gap positioning through plug-in self-locking and eliminating micro-displacement caused by vibration / inertia.

[0010] Preferably, the locking component includes a locking block, which is installed on the elevator, and a plurality of locking buckles are installed on the top of the locking block; in this solution, the locking block and locking buckles can form a mechanical self-locking mechanism, resisting lateral forces during transfer and ensuring that the workpiece does not shake.

[0011] Preferably, the locked component includes a rectangular block embedded inside the guide plate, and the bottom of the rectangular block has a locking groove corresponding to the locking buckle. In this design, the rectangular block is embedded inside the guide plate, which can enhance local rigidity and prevent the locking groove from deforming under force. The locking groove and the locking buckle are precisely matched to provide a unique alignment reference surface, physically eliminating the X / Y degree of freedom and providing an absolutely stable base for riveting.

[0012] Preferably, the moving mechanism includes a moving rod located inside the base frame and rotatably connected to it. A moving nut is threaded onto the side wall of the moving rod, and an L-shaped plate is fitted onto the side wall of the moving nut. A horizontal plate is inserted through the L-shaped plate, which is fixedly connected to the base frame. The L-shaped plate is slidably connected to the horizontal plate. In this design, the moving rod and the moving nut convert rotational motion into high-precision linear motion, avoiding impacts caused by cylinder thrust fluctuations. The dual guiding constraints of the horizontal plate and the L-shaped plate prevent pitching / swaying during horizontal transfer, ensuring precise alignment of the locking buckle and the locking groove.

[0013] Preferably, the lifting platform includes a housing mounted on the L-shaped plate. An electric cylinder is located inside the housing and is fixedly connected to the L-shaped plate. The output shaft of the electric cylinder is fixedly connected to the locking member. The bottom of the locking member has a guide post, one end of which is fixedly connected to the locking member, and the other end of which extends into the interior of the electric cylinder. In this design, the electric cylinder provides controllable thrust (avoiding air pressure fluctuations) to ensure the locking buckle is smoothly embedded in the locking groove. The guide post penetrates the locking member and the electric cylinder, providing forced vertical guidance to prevent deflection during the lifting process, which could lead to jamming or wear during insertion.

[0014] Preferably, the riveting machine includes a base plate located inside the housing and fixedly connected to the base frame. A top plate is located above the base plate. Two sliding columns are located between the base plate and the top plate, connecting them via the two sliding columns. A press is mounted on the top of the top plate, and a pressure plate is mounted on the output shaft of the press. The pressure plate is slidably connected to the sliding columns. In this design, the double-column guide pressure plate presses vertically downwards, preventing uneven crushing of the sealing ring caused by riveting head misalignment. The press and pressure plate provide stable riveting force, ensuring uniform plastic deformation of the contact surface between the pole and the cover plate.

[0015] Preferably, the base plate has a guide groove at the middle position, which corresponds to the self-locking mobile device. Two guide members are located below the pressure plate, on either side of the guide groove. In this design, the guide groove is aligned with the path of the self-locking mobile device, allowing the locking member to pass through and providing final guidance for the workpiece to enter the riveting area. The dual guide members contact both sides of the workpiece before the pressure plate presses down, performing secondary correction of minor residual deviations. This forms a double safety net of self-locking during transfer and pre-riveting correction, completely avoiding the risks of uneven sealing ring crushing and poor pole connection.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This equipment uses a precise fit between the locking buckle and the locking groove to form a full-circumferential mechanical self-locking during the lifting process, physically eliminating the X / Y degree of freedom. Throughout the transfer process, the workpiece and the locking parts are in rigid surface contact, effectively resisting the effects of vibration, inertia, and friction fluctuations. It eliminates the risk of failure such as uneven crushing of the sealing ring and poor connection of the pole from the structural source, improves the first-time riveting qualification rate of the product, and completely eliminates the micro-displacement during transfer, thus completely avoiding potential quality problems.

[0018] 2. This equipment achieves physical self-alignment through the mechanical contour of the opening on the turntable and the locking mechanism path. The transfer trigger relies entirely on the rigid timing coupling of the turntable rotation phase and the lead screw stroke, without the need for photoelectric sensors or proximity switches to participate in the judgment. In the battery production line environment with high concentration of metal dust and oil mist, the alignment success rate remains at 100%. Faults such as false triggering, jamming, and mechanical collision caused by sensor contamination are eliminated, and the unplanned downtime rate of the equipment is reduced. This allows the equipment to get rid of sensor dependence and achieve highly reliable operation under harsh working conditions.

[0019] 3. This equipment uses a single mating pair of locking buckle and locking groove as its core, integrating the horizontal conveying function of the moving lever and the vertical locking function of the electric cylinder, replacing the traditional pusher cylinder, multi-stage guide rail and complex linkage mechanism. The number of moving parts is reduced and the equipment is more compact. The modular design of rectangular blocks embedded in the guide plate, together with the anti-slip structure of the positioning column, shortens the replacement time of key wear parts and reduces the maintenance time of a single maintenance from more than 2 hours to less than 30 minutes. Therefore, the structure of this equipment is highly integrated and simplified, and the operation and maintenance efficiency is significantly improved.

[0020] 4. This equipment uses the sliding pair of the horizontal plate and the L-shaped plate and the precision transmission of the lead screw to eliminate the pitch / sway of the transfer; while the guide post passes through the locking part and the electric cylinder to force a vertical movement trajectory; the locking buckle is embedded in the locking groove to form a rigid connection, so that the triple constraint of this equipment works together to ensure that the transfer process is uniform, stable and impact-free, effectively protecting the assembled sealing rings, insulating gaskets and other precision components, and avoiding assembly failure caused by secondary disturbances.

[0049] Specifically, the surface of the slide column 33 is ultra-fine ground and hard chrome plated to improve wear resistance and smoothness of sliding; a self-aligning bearing seat is added at the connection between the slide column 33 and the top plate 32 and the bottom plate 31 to automatically compensate for minor installation deviations and prevent the pressure plate 35 from jamming; the press 34 adopts a servo electric cylinder and integrates a high-precision pressure sensor and displacement encoder to monitor the riveting force and stroke in real time and realize closed-loop control of process parameters; the lower surface of the pressure plate 35 is equipped with a quick-change mold interface, which can complete the mold change within 30 seconds to adapt to multiple specifications of cover plates; the working surface of the bottom plate 31 can be embedded with stainless steel positioning pins and vacuum suction cups to double fix the workpiece and prevent displacement during riveting.

[0050] For further details, please refer to Figure 4 and Figure 5 The base plate 31 has a guide groove 36 in the middle position, which corresponds to the self-locking mobile device 5. There are two guides 37 below the pressure plate 35, which are located on both sides of the guide groove 36.

[0052] The workflow of this embodiment is as follows: First, the operator places the battery cover assembly (including terminals, sealing rings, etc.) on the guide plate 442 of the loading machine 44. The guide groove 441 forms a horizontal constraint on the guide plate 442, and the top positioning post 443 effectively prevents the guide plate 442 from sliding backward due to inertia during subsequent rotation, ensuring that the initial positioning reference of the workpiece is stable and reliable. Then, the rotating machine 42 drives the turntable 43 to rotate, accurately transferring the loading machine 44 carrying the workpiece to directly above the self-locking mobile device 5. Then, the opening 45 at the corresponding position of the turntable 43 and the loading machine 44 is strictly aligned with the locking member 53, providing a physical channel for the subsequent vertical locking action. Subsequently, the lifting machine 52 is started, and the electric cylinder 522 drives the locking member 53 to rise vertically. The guide post 523 ensures that the movement trajectory is absolutely vertical. The locking buckle 532 passes through the opening 45 of the turntable 43 and is accurately embedded in the locking groove 542 of the rectangular block 541 at the bottom of the guide plate 442, thereby realizing a zero-gap self-locking connection between the workpiece and the transfer mechanism. The rear moving machine 51 starts, the moving lever 511 rotates, and the moving nut 512 drives the L-shaped plate 513 to slide horizontally along the horizontal plate 514. The locking part 53 drags the self-locking guide plate 442 smoothly out of the turntable 43 area, guided by the guide groove 36 in the middle of the base plate 31, and accurately fed into the working area of ​​the riveting machine 3. After the guide plate 442 is in place, the two guide parts 37 under the pressure plate 35 first contact the two sides of the workpiece, and perform micro-deviation flexible correction on the workpiece before the press 34 presses down. Press 34 drives the pressure plate 35 to press down vertically along the slide column 33 to precisely rivet the battery cover assembly. After riveting, the pressure plate 35 rises and resets, the moving machine 51 moves in the opposite direction, and smoothly moves the guide plate 442 back to the top of the turntable 43 along the original path. The lifting machine 52 descends, the locking buckle 532 disengages from the locking groove 542, and the turntable 43 rotates to the next station. The riveted workpiece enters the unloading area, and the idle loading machine 44 rotates to the loading position to receive new workpieces, seamlessly connecting to the next work cycle.
