Description

Technical Field

[0002] Electrolyte filling is a step in the battery manufacturing process. After filling, to avoid residual electrolyte at the filling hole, it is often necessary to wipe the filling hole of the battery with a wiping cloth to ensure its cleanliness.

[0003] Currently, lithium battery device liquid injection port wiping mechanisms only wipe the injection port itself, and most of these methods involve cutting or rolling non-woven fabric to clean it. They cannot wipe the entire top cover, and the movement is limited; unlike human wiping, it cannot rotate within the injection port, and cotton swabs cannot be used. This wiping method is inefficient, labor-intensive, and unsafe, and it suffers from missed areas and inconsistent wiping results. Achieving a complete wipe requires additional manual labor for secondary cleaning. Existing wiping methods not only have poor cleaning results but also incur high labor costs. Utility Model Content

This not only meets the high-efficiency cleaning needs around the battery electrolyte filling hole but also ensures that the delicate structure inside the hole is not damaged. Furthermore, the operation of the pick-and-place device improves wiping efficiency and saves labor costs. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0044] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0045] This utility model embodiment provides a pickup device 1, such as... Figures 1 to 2 As shown, the pickup device 1 includes: a base 11, a vacuum column 12, and at least two grippers 13; the base 11 is cylindrical and has a mounting surface 111 with a geometric center; at least two grippers 13 are disposed on the mounting surface 111 and slidably connected to it; the at least two grippers 13 are evenly distributed along the circumference of the base 11, and are able to move closer to each other or further away from the geometric center of the mounting surface 111; the vacuum column 12 is disposed at the geometric center of the mounting surface 111 and is slidably connected to it. The base 11 is slidably connected, and the vacuum column 12 has an end, which is the end of the vacuum column 12 away from the mounting surface 111. Along the axial direction of the vacuum column 12, the vacuum column 12 has a first position and a second position relative to the base 11. When the vacuum column 12 is in the first position, the end is lower than or flush with the chuck 13. When the vacuum column 12 is in the second position, the end protrudes from the chuck 13. The vacuum column 12 can move relative to the base 11 to the first position or the second position. The vacuum column 12 is provided with an adsorption hole 121, which is located at the end of the vacuum column 12 away from the base 11.

[0046] The base 11 serves as the basic support structure for the pickup device 1, providing a mounting carrier for other components. The mounting surface 111 is used to mount the chuck 13 and the vacuum column 12, and is the reference surface for the movement and fit between the components. The mounting surface 111 has a geometric center along the axial direction of the base 11, and the mounting position of the vacuum column 12 is also the geometric center of symmetry for the movement of the chuck 13.

[0047] The vacuum column 12 grips the workpiece through vacuum adsorption and, in conjunction with the chuck 13, moves to pick up workpieces under different working conditions. It can move relative to the base 11 along its own axis, switching between a first position and a second position. The adsorption hole 121 is located at the end away from the base 11 and connects to the vacuum system. It adsorbs the workpiece through negative pressure. At different positions, the top of the vacuum column 12 protrudes differently from the mounting surface 111, facilitating the pickup of cleaning tools such as cotton swabs. The vacuum column 12 has an end, which is the end of the vacuum column 12 away from the mounting surface 111. Along the axis of the vacuum column 12, the vacuum column 12 has a first position and a second position relative to the base 11. When the vacuum column 12 is in the first position, the end of the vacuum column 12 is lower than or flush with the chuck 13. When the vacuum column 12 is in the second position, the end of the vacuum column 12 protrudes from the chuck 13. The vacuum column 12 can move relative to the base 11 to either the first or second position. When the workpiece surface is flat and suitable for vacuum adsorption, switch to the first position to avoid chuck interference; when the workpiece needs to withstand large cutting forces or has a non-flat surface, switch to the first position and the vacuum column retracts to avoid damage.

[0048] At least two chucks 13 clamp or release the workpiece through relative movement, cooperating with the vacuum column 12 to complete a compound gripping operation. The at least two chucks 13 are evenly distributed along the circumference of the cylindrical base 11. If a two-chuck design is used, the included angle between the two chucks is 180°, which is suitable for simple opening and closing clamping. If a three-chuck design is used, the included angle between each pair of chucks is 120°, and the radial forces of each chuck are balanced, which can effectively counteract the deflection tendency of the workpiece when it rotates or is subjected to force, and improve the stability during processing or assembly. When there are four chucks, the four chucks are distributed in a cross shape, which can provide stronger constraints and high flexibility.

[0049] At least two grippers 13 slide radially along the mounting surface 111, allowing for adjustable clamping spacing and easy gripping of cleaning tools such as lint-free cloths. Multiple grippers 13 move towards or away from the geometric center of the mounting surface 111, simultaneously approaching or moving away to mechanically clamp the cleaning tools. The grippers 13 can hold lint-free cloths for wiping the battery surface for large-area cleaning. The grippers 13 slide symmetrically along the axial geometric center of the base 11, ensuring uniform clamping force distribution and preventing deformation or displacement of the workpiece due to uneven force. The suction hole 121 of the vacuum column 12 is used to insert cotton swabs for thorough cleaning of the injection holes. The independent movement of the vacuum column 12 and the grippers 13 allows for switching between different gripping modes, providing reliable fixation for mechanical clamping.

[0050] Both the lint-free cloth and cotton swabs are disposable tools. The automated pick-and-place mechanism 1 ensures that each battery uses a fresh cleaning tool, avoiding the contamination risks associated with reusing tools in traditional manual operations. The pick-and-place mechanism 1 uses a clamp to pick up the lint-free cloth for large-area pre-cleaning, and the vacuum column 12 inserts the cotton swab to complete the fine cleaning inside the holes. This not only meets the high-efficiency cleaning needs around the battery filling holes but also ensures that the delicate structures inside the holes are not damaged. The operation of the pick-and-place mechanism 1 also improves wiping efficiency and saves labor costs.

[0051] In one embodiment, such as Figures 1 to 2 As shown, there are four chucks 13, and the mounting surface 111 is provided with a cross-shaped slide groove 1111; the cross-shaped slide groove 1111 has four slide grooves 1111a, and the adjacent slide grooves 1111a are perpendicular to each other; one chuck 13 is disposed in one slide groove 1111a, and the four chucks 13 can simultaneously approach or move away from each other.

[0052] The cross-shaped groove 1111 on the mounting surface 111 consists of two mutually perpendicular grooves, forming four symmetrically distributed radial grooves 1111a, each groove 1111a corresponding to a chuck 13. The four chucks 13 achieve synchronous movement through mechanical linkage, that is, they move closer to or further away from each other simultaneously.

[0053] The two opposing chucks 13 move synchronously to form a bidirectional centering clamping force. The movement of the chucks 13 is based on the axial geometric center of the base 11. During clamping, the geometric center of the workpiece is automatically aligned with the axis of the vacuum column 12 (the geometric center of the base 11), reducing manual or visual calibration steps and improving automation efficiency.

[0054] The collets 13, arranged in pairs facing each other, are compatible with various base shapes 11. When the base 11 is cylindrical, the four collets 13 evenly contact the outer periphery and are fixed by symmetrical forces. When the base 11 is a cuboid workpiece, the collets 13 facing each other abut against opposite sides, forming a stable four-sided clamping. When the base 11 is an irregularly shaped symmetrical workpiece, as long as the base 11 has geometric central symmetry, it can be adapted by adjusting the position of the collets 13.

[0055] In one embodiment, such as Figures 1 to 2 As shown, the geometric center of the mounting surface 111 is provided with a mounting hole 1112, and the vacuum column 12 is embedded in the mounting hole 1112. Along the axial direction of the vacuum column 12, the vacuum column 12 can move relative to the base 11 to the first position or the second position.

[0056] The mounting hole is located at the geometric center of the mounting surface 111 and is coaxial with the axial geometric center of the base 11 (i.e. the symmetrical geometric center of the cross-shaped slide groove 1111). This ensures that the axis of the vacuum column 12 coincides with the movement geometric center of the chuck 13, making the vacuum adsorption force and the mechanical clamping force collinear and avoiding workpiece displacement caused by eccentric force.

[0057] When the vacuum column 12 is in the first position, the end of the vacuum column 12 is lower than or flush with the clamping surface of the chuck 13, and the chuck 13 performs clamping action independently. When the vacuum column 12 is in the second position, the end of the vacuum column 12 protrudes from the clamping surface of the chuck 13.

[0058] The vacuum column 12 can adjust its protrusion according to the workpiece height to avoid interference and collision. The vacuum column 12 achieves adsorption and avoidance functions through position switching, eliminating the need for a separate adsorption module or robotic arm, thus reducing the number of hardware components and the complexity of the control system. The sliding connection structure between the vacuum column 12 and the base 11 can be designed as a quick-release assembly. When the adsorption hole 121 is blocked or mechanically worn, it can be maintained or replaced individually without disassembling the entire pickup device 1, shortening downtime.

[0059] In one embodiment, such as Figure 1 As shown, the chuck 13 includes a clamping part 131 and a connecting part 132; the clamping part 131 is disposed on the side of the connecting part 132 away from the base 11 and is rotatably connected to the connecting part 132, while the connecting part 132 is slidably connected to the base 11.

[0060] The clamping part 131 and the connecting part 132 of the chuck 13 adopt a rotating connection design. The clamping part 131 can rotate around the rotation axis. When in contact with the workpiece surface, it can automatically adjust the angle according to the shape of the workpiece, reducing design costs. Multi-angle contact allows the clamping force to be distributed over a larger area, reducing local stress concentration. Furthermore, in the non-working state, the clamping part 131 can be rotated and retracted, reducing the overall size.

[0061] In one embodiment, such as Figure 3 As shown, the pickup device 1 also includes a multi-axis transmission mechanism 14 and a mounting base 15; one end of the multi-axis transmission mechanism 14 is fixedly connected to the base 11, and the other end of the multi-axis transmission mechanism 14 is fixedly connected to the mounting base 15.

[0062] The multi-axis transmission mechanism 14 is a transmission device that enables multi-degree-of-freedom motion. It connects the base 11 and the mounting base 15, transmits power, and controls the spatial motion trajectory of the base 11. The mounting base 15 serves as the overall mounting foundation for the pickup device 1, can be connected to external equipment, and provides structural support.

[0063] The multi-axis transmission mechanism 14 can drive the base 11 to move in three-dimensional space or rotational direction, enabling the pickup device 1 to accurately position the workpiece or target area at different locations. Through the combined movement of the multi-axis transmission mechanism 14, the posture of the vacuum column 12 and the chuck 13 can be adjusted to meet the pickup requirements of complex angles.

[0064] The high-precision control of the multi-axis transmission mechanism 14 ensures that the suction hole 121 of the vacuum column 12 is accurately aligned with the workpiece surface, or that the chuck 13 precisely clamps the edge of the workpiece, reducing gripping errors. The mounting base 15 serves as an integrated interface, which can integrate the multi-axis transmission mechanism 14, the base 11, and the gripping components into an independent module, making it easy to install on different equipment and reducing production line modification costs.

[0065] This utility model embodiment also provides a battery cleaning device, such as... Figure 4 As shown, the battery cleaning equipment includes the aforementioned pickup device 1.

[0066] Using the aforementioned pickup device 1 on a battery cleaning device makes the cleaning device more efficient and effective at wiping, while also saving labor costs.

[0067] In one embodiment, such as Figure 4 As shown, the battery cleaning equipment also includes: a frame 2, a first feeding mechanism 3, a second feeding mechanism 4, a tray 5, and a transmission assembly 6. The picking device 1 is slidably connected to the frame 2, the first feeding mechanism 3 is fixedly connected to the frame 2, and the second feeding mechanism 4 is fixedly connected to the frame 2; the tray 5 is disposed on the transmission assembly 6 and is used to place the batteries to be cleaned.

[0068] The frame 2 is the main support structure of the equipment, providing rigid support for the first feeding mechanism 3, the second feeding mechanism 4, the transmission component 6, etc.

[0069] The first feeding mechanism 3 is used to place cotton swabs. The second feeding mechanism 4 is used to place cleanroom wipes.

[0070] The tray 5 is used to carry the batteries to be cleaned, ensuring that the batteries are in a fixed position during transportation and cleaning, and works with the transmission component 6 to realize the batch transportation and positioning of batteries.

[0071] The transmission component 6 is used to move the tray 5 and the battery within the device.

[0072] The battery cleaning equipment achieves a highly efficient and automated cleaning process through the coordinated operation of its components. The frame 2 provides stable support for the equipment, and the picking device 1 is slidably connected to the frame 2, allowing it to flexibly pick up batteries placed on the tray 5. The transmission component 6 moves the tray 5 along a preset path, allowing the batteries to pass through each station sequentially. The first feeding mechanism 3 and the second feeding mechanism 4 precisely supply different cleaning materials, completing the multi-step cleaning process. This design not only significantly reduces manual intervention, improving cleaning efficiency and capacity, but also ensures consistent cleaning quality through standardized operations. Furthermore, the modular structure facilitates equipment maintenance, and the parameters can be adjusted to accommodate the cleaning needs of different battery types, effectively reducing production costs and safety risks.

[0073] In one embodiment, such as Figure 4 , Figure 5 As shown, the first feeding mechanism 3 includes: a first feeding box 31; the first feeding box 31 is fixedly connected to the frame 2; the first feeding box 31 is provided with a plurality of grooves 311, which are used to place cotton swabs; the distance between adjacent grooves 311 is greater than the radius of the vacuum column 12.

[0074] The first feed box 31 is fixedly connected to the frame 2 and is used to store and supply cotton swabs. A groove 311 is provided inside the first feed box 31 to store cotton swabs individually, ensuring that the cotton swabs are arranged in an orderly manner and are easy to pick up.

[0075] The vacuum column 12 extracts the cotton swab from the groove 311 by adsorption force.

[0076] The spacing between adjacent grooves 311 is greater than the radius of the vacuum column 12, which prevents the vacuum column 12 from contacting or colliding with adjacent cotton swabs when adsorbing them. This ensures that only a single cotton swab can be accurately adsorbed each time, improving the accuracy and stability of feeding and avoiding the decrease in cleaning efficiency or waste of consumables caused by multiple cotton swabs being picked up at the same time.

[0077] In one embodiment, such as Figure 4 , Figure 6 As shown, the second feeding mechanism 4 includes: a second feeding box 41 and a driving member 42; the second feeding box 41 is fixedly connected to the frame 2, and the second feeding box 41 is located on the side of the driving member 42 away from the transmission component 6 and is fixedly connected to the driving member 42; the second feeding box 41 has an opening 411, and the opening 411 faces the side away from the driving member 42.

[0078] The second feed box 41 is fixedly connected to the frame 2 and is used to store and supply the clean cloth required in the cleaning process. It has an opening 411 in its structure, with the opening direction away from the drive component 42, so that the picking device 1 can pick up the clean cloth.

[0079] The drive unit 42 is fixedly connected to the second feed box 41 and can be a power device such as a motor or cylinder, used to drive the clean cloth in the second feed box 41.

[0080] The transfer component 6 is used to carry the tray 5 and transport the batteries to be cleaned.

[0081] The drive unit 42 controls the output of the clean cloth in the second feed box 41 through the opening 411 via power output, which can realize operations such as quantitative spraying of cleaning agent and precise dispensing of wiping cloth.

[0082] The second feeding box 41 is fixedly connected to the frame 2, and the drive unit 42 is integrated into one side of the feeding box. The overall layout is compact and occupies little space. At the same time, the design of the opening 411 facilitates quick replacement of material containers or cleaning of the feeding channel, reduces the difficulty of equipment maintenance, and ensures continuous operation of the production line.

[0083] In one embodiment, such as Figure 3 As shown, when the pickup device 1 includes a multi-axis transmission mechanism 14 and a mounting base 15, the battery cleaning device also includes a first slide rail 7, which is fixedly connected to the frame 2; the mounting base 15 is slidably connected to the first slide rail 7.

[0084] The first slide rail 7 is fixedly connected to the frame 2, providing a linear sliding track for the mounting base 15, guiding the pickup device 1 to move in a specific direction, and ensuring the accuracy and stability of the movement trajectory.

[0085] The sliding connection between the mounting base 15 and the first slide rail 7 allows the picking device 1 to quickly move back and forth between the feeding station and the cleaning station along the fixed track of the frame 2. The first slide rail 7 provides rigid support and guidance for the picking device 1, reducing swaying or deviation during multi-axis movement, and ensuring the stability of the movement trajectory, especially during high-speed movement or when picking up wiping materials.

[0086] Through the coordinated design of the multi-axis transmission mechanism 14, the mounting base 15 and the first slide rail 7, the battery cleaning equipment achieves precise control and efficient movement of the picking device 1 in the spatial dimension, ensuring the automated connection between each workstation in the cleaning process and improving the flexibility, stability and production efficiency of the equipment.

[0087] Fully automated multi-axis motion control replaces manual picking and positioning operations, reducing manpower input and avoiding fluctuations in cleaning quality or material waste caused by human error, thus reducing production costs and improving production safety.

[0088] In one embodiment, such as Figure 3 As shown, the battery cleaning equipment also includes a vision inspection system 8, a second slide rail 9, and a third slide rail 10; the vision inspection system 8 includes a first camera 81 and a second camera 82; base point coordinates 51 are provided at at least two corners of the tray 5; the second slide rail 9 and the third slide rail 10 are respectively fixedly connected to the frame 2; the first camera 81 is slidably connected to the second slide rail 9, and the second camera 82 is slidably connected to the third slide rail 10.

[0089] The first camera 81 slides along a specific direction via the second slide rail 9 to capture partial images of the tray 5 or the battery; the second camera 82 slides along a specific direction via the third slide rail 10, working in conjunction with the first camera 81 to locate the battery to be cleaned and detect the cleaning effect by capturing images of the battery.

[0090] The base point coordinates 51 are protrusions, indentations or specific patterns pre-set on at least two corners of the tray 5, used by the vision system to quickly identify the position and orientation of the tray 5 and establish a coordinate system reference.

[0091] Both are fixedly connected to the frame 2, providing linear sliding tracks for the first camera 81 and the second camera 82 respectively. Through the linear movement of the sliding tracks, the camera can adjust the shooting position and angle to cover different areas of the tray 5 or adapt to the needs of battery detection of different sizes.

[0092] The first camera 81 and the second camera 82 calculate the difference between the actual position and the theoretical position of the tray 5 and the battery in real time by detecting the positional deviation of the base point coordinates.

[0093] When the transmission component 6 delivers the tray 5 to the cleaning station, the vision system first identifies the base point coordinates 51. If the tray 5 is detected to have shifted or rotated, the movement trajectory of the pickup device 1 can be adjusted through the multi-axis transmission mechanism 14 to compensate for the positional deviation and ensure that the cotton swab or cleaning tool is accurately aligned with the battery surface.

[0094] During cleaning, the first camera 81 captures images of the batteries, and the image algorithm analyzes and identifies the batteries that need cleaning. Using base point coordinates, the system locates the batteries to be cleaned. The picking device 1 picks up a lint-free cloth and cotton swabs to clean the batteries. Then, the second camera 82 captures images of the batteries, and the image algorithm analyzes and determines whether the cleaning meets the standards. If a defective product is detected, the system can trigger an alarm or automatically sort the batteries to a rework station.

[0095] The visual inspection system replaces manual labor in positioning, inspection, and quality judgment, avoiding human error and operational delays. Especially in nighttime production or high-risk environments, it can significantly improve production continuity and safety.

[0096] The image data collected by the vision inspection system 8 can be stored in the equipment management system to trace the historical records of battery cleaning, such as cleaning time, stain type, and treatment plan, providing data support for process optimization. By analyzing the stain distribution patterns of batch batteries, the type of cleaning agent in the feeding mechanism or the movement trajectory of the cleaning tools can be adjusted to improve overall cleaning efficiency.
