Description

TECHNICAL FIELD

[0001] The utility model relates to battery component transfer technical field, especially in a kind of transfer tool and battery cooling flat tube transfer system. BACKGROUND

[0002] In the field of battery manufacturing, the cooling pipe as a key component, its structure is usually presented as length, thin-walled flat tube shape, more using aluminum alloy, composite material and other lightweight fragile material. The current production and transfer link of the component mainly relies on manual operation: the worker holds flat tube two ends or middle region directly by both hands to carry and transfer. Because the flat tube structure is insufficiently rigid and the surface protective layer is easy to be damaged, local stress concentration is easy to cause pipe body plastic deformation or even breakage during manual gripping, especially when the gripping position deviates from the center of mass, the bending damage caused by torque imbalance is more significant. At the same time, the pipe body is easy to produce surface scratches during operation due to mutual collision or contact with the tool, which directly affects the heat dissipation performance and sealing reliability.

[0003] The existing carrying mode has many technical defects: first, the operation force and balance are difficult to accurately control, causing structural damage and appearance quality decline of the component; second, the rhythm of manual carrying is difficult to match the rhythm of automatic production line, becoming a bottleneck of large-scale production; third, workers are at risk of being cut by the pipe body with sharp edges, and fatigue work is easy to cause slipping accidents; in addition, the randomness of manual operation leads to lack of repeated precision of gripping point and placing posture, affecting the stability of subsequent welding, assembly and other processes. These problems seriously restrict the quality control and production efficiency improvement of battery cooling pipe manufacturing. UTILITY MODEL CONTENTS

[0004] In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide a transfer tool for transferring battery cooling flat tube.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a transfer tool for transferring battery cooling flat tube, which comprises:

[0006] A tool base plate is used to connect a conveying mechanism to suspend the battery cooling flat tube;

[0007] A profiling groove is provided on the surface of the tool base plate, the profiling groove is recessed along the first direction, the profiling groove extends to the lower plate edge of the tool base plate, and the profiling groove is used to accommodate the end of the battery cooling flat tube;

[0008] A clamping arm is arranged on one side of the profiling groove slot to clamp and fix the end of the battery cooling flat tube in the profiling groove.

[0009] In an optional embodiment of the utility model, the profiling groove includes a first region and a second region, the first region is above the second region, and the groove width of the first region in the second direction is greater than the groove width of the second region in the second direction.

[0010] In an optional embodiment of the utility model, the profiling grooves are arranged at intervals along the second direction, and one clamping arm is arranged corresponding to each profiling groove.

[0011] In an optional embodiment of the utility model, the clamping arm is arranged on the upper side of the profiling groove.

[0012] In an optional embodiment of the utility model, the clamping arm includes a telescopic part, and the telescopic part is configured to be able to shield or avoid the profiling groove.

[0013] In an optional embodiment of the utility model, a knob for driving the telescopic part to move along the first direction is arranged on the clamping arm.

[0014] In an optional embodiment of the utility model, a buffer layer is arranged on the surface of the telescopic part and / or the profiling groove.

[0015] In an optional embodiment of the utility model, a roller is arranged on the plate surface of the tooling base plate away from the profiling groove.

[0016] In an optional embodiment of the utility model, a handle is arranged on the plate surface of the tooling base plate on the side of the profiling groove.

[0017] The utility model further provides a battery cooling flat pipe transfer system, which comprises:

[0018] A conveying unit;

[0019] A transfer tool connected to the conveying unit, wherein the transfer tool is the transfer tool as described.

[0020] The technical effect of the utility model lies in: the gravity of the flat pipe is dispersed to the conveying equipment through the suspension type design, the local stress problem of manual carrying is avoided, direct connection with the production line automation equipment is realized, and the coherence and beat control precision of the transfer process are obviously improved. The recess structure of the groove and the outer shape of the flat pipe end form inclusive cooperation, the contact area is maximized after the pipe body is embedded, and the pressure of unit area is effectively reduced; the structure that the groove extends to the edge of the base plate is convenient for the flat pipe to slide into positioning along the gravity direction, and rigid friction with the groove wall when the pipe body moves laterally is avoided, and the risk of scratching is eliminated from the physical structure. After the flat pipe is limited by the profiling groove, the clamping arm further restricts the freedom degree of the pipe body through lateral pressure, and a double fixing mechanism is formed. The design prevents the swing or slipping of the flat pipe due to inertia in the suspension state, and the interference of external vibration on the stability of the pipe body is offset through rigid clamping, and is especially suitable for nondestructive holding of fragile materials.

[0027] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] Cooling tubes are a critical component in battery manufacturing. They are typically long, thin-walled flat tubes made of fragile aluminum alloys or composite materials. While these cooling tubes offer good heat dissipation, their fragile materials and insufficient structural rigidity make them susceptible to deformation, breakage, or surface scratches from external forces. Therefore, protecting the integrity of cooling tubes during handling, preventing damage, and improving production efficiency have become pressing technical challenges in the battery manufacturing industry.

[0030] Currently, the transfer of cooling pipes on the production line mainly relies on manual operation. Operators typically handle the pipes by directly grasping both ends or the middle section with their hands. However, the considerable length and fragile material of flat pipes, coupled with insufficient protective coatings on their surface, make manual handling highly susceptible to mechanical imbalances. Operators struggle to precisely control the handling force, often leading to bending, breakage, or even surface scratches due to stress concentration and torque imbalance during transport. These problems not only affect the structural and aesthetic quality of the cooling pipes but also directly impact their heat dissipation performance and sealing during subsequent use.

[0031] Furthermore, manual handling is inefficient and cannot meet the high efficiency and precision requirements of modern battery manufacturing. Because manual handling relies on the operator's skill level, and the stability and consistency of each operation are difficult to guarantee, this method is particularly unsuitable for large-scale production, limiting the automation upgrade of production lines and the improvement of production speed.

[0032] In terms of safety, when manually handling cooling pipes, workers need to directly contact the sharp edges of the pipes, posing a risk of cuts. Prolonged contact with these vulnerable parts may also lead to the cooling pipes slipping or falling due to operator fatigue or accidental errors, resulting in injury to workers or damage to the pipes.

[0033] In addition, manual operation is difficult to ensure stability and accuracy in each handling process, especially in handling posture and grabbing point, which often has certain randomness. Such randomness not only affects the handling efficiency, but also may affect the stability of subsequent processing technology (such as welding, assembly, etc.), and further affect the consistency and precision of product quality.

[0034] Therefore, the existing manual handling mode has problems of easy damage, low efficiency, safety hazards and poor consistency in the process of manufacturing cooling pipes, and needs to be improved and optimized to improve the overall production efficiency and product quality.

[0035] To achieve the above and other related purposes, as shown in Figures 2 to 4 The utility model provides a transfer tool for transferring battery cooling flat pipe 1. As shown in Figure 1 The battery cooling flat pipe 1 includes a plurality of flat pipes arranged side by side, and the two ends of the two flat pipes are connected with the slightly protruding horizontal pipe 2.

[0036] The transfer tool includes a tool base plate 10, a profiling groove 20 and a clamping arm 30.

[0037] The tool base plate 10 is used to connect the conveying mechanism to suspend the battery cooling flat pipe 1, and the tool base plate 10 serves as the bearing body and is connected with the conveying mechanism (such as mechanical arm, conveying belt) in a suspended manner to realize the automatic connection of flat pipe transfer. Since the battery cooling flat pipe 1 is usually made of aluminum alloy material, it is light in weight but weak in rigidity, and the suspended manner can avoid the bending risk in traditional manual handling. For example, the tool base plate 10 can be integrated into the AGV trolley or truss mechanical arm system to match the automatic process of production line. The uneven force problem in manual handling is eliminated, and the plastic deformation or fracture of flat pipe caused by local stress is avoided; the transfer mechanism is linked with the conveying mechanism to improve the stability of transfer rhythm and meet the demand of large-scale production.

[0038] A profiled groove 20 is provided on the plate surface of the tooling base plate 10, which is recessed along a first direction corresponding to the thickness direction of the flat tube, and extends to the lower edge of the tooling base plate 10. The profiled groove 20 is used to accommodate the end of the battery cooling flat tube 1, and can accommodate two flat tubes at the same time. The profiled groove 20 is recessed along the tooling base plate 10 and extends to the lower edge, and its shape matches the profile of the cross tube 2 at the end of the flat tube, which is used for accurate positioning and preliminary fixation. According to the shape of the cross tube 2 protruding on both sides of the end of the flat tube, the profiled groove 20 can be designed as a symmetrical groove to ensure that the cross tube 2 naturally fits after being embedded. The opening design extending to the lower edge facilitates quick alignment when the flat tube is vertically lifted (for example, from a horizontal conveying belt to a vertical suspension state). By using inclusive contact, the hard friction between the flat tube and the tooling is reduced, and surface scratches (especially for aluminum alloy thin-walled tubes) are avoided; using gravity to assist positioning reduces the complexity of operation and improves the transfer efficiency.

[0039] The clamping arm 30 is provided on one side of the opening of the profiled groove 20 to clamp and fix the end of the battery cooling flat tube 1 in the profiled groove 20. The clamping arm 30 is provided on the opening side of the profiled groove 20, and a lateral clamping force is applied to the end of the flat tube embedded in the groove by a mechanical or pneumatic method, forming double fixation. According to the size of the cross tube 2 at the end of the flat tube, the clamping arm 30 can be configured with a flexible contact surface (such as a silicone pad) to disperse the pressure. The clamping arm 30 can be designed as a linkage mechanism to automatically trigger the clamping / release action when the conveying mechanism is lifted, realizing unmanned operation. The clamping arm 30 prevents collision damage of the flat tube due to inertial swing during suspension, ensures the consistency of the posture of multiple parallel flat tubes during transfer, and avoids misalignment affecting subsequent assembly (such as the fit of the liquid cooling pipe and the battery module).

[0040] As shown in Figures 3 to 4 The profiled groove 20 includes a first region 21 and a second region 22, the first region 21 is located above the second region 22, and the groove width of the first region 21 in the second direction is greater than the groove width of the second region 22 in the second direction. The first region 21 corresponds to the cross tube 2 slightly protruding on both sides of one end of the flat tube, and the cross tube 2 can be hung in the first region 21 to prevent falling off. In this application, above refers to the direction of the transfer tooling in the suspended state.

[0041] As shown in Figures 2 to 4As shown, the profiled grooves 20 are arranged in multiple along a second direction, the second direction is a horizontal direction and parallel to the plate surface of the tooling base plate 10, each groove corresponds to the end of a flat tube, realizing the simultaneous clamping and transfer of multiple flat tubes. A clamping arm 30 is arranged corresponding to each profiled groove 20, ensuring that the clamping force of a single flat tube is independently controllable, avoiding uneven pressure caused by clamping linkage. It is suitable for the structure of multiple parallel flat tubes in the battery module (such as the heat dissipation pipe arranged in the inner layer of the power battery pack), and can adapt to flat tube groups of different lengths or spacings, and meet the mixed line production demand by adjusting the interval distance of the profiled grooves 20.

[0042] The synchronous grabbing and releasing of multiple flat tubes are completed in a single operation, greatly shortening the batch transfer time. The clamping force of each flat tube does not affect each other, avoiding the whole clamping failure caused by the deformation or position deviation of a certain tube. The interval distance of the profiled grooves 20 is adjustable, which is compatible with different battery module flat tube arrangement schemes (such as mixed layout of densely arranged heat dissipation pipes and sparsely arranged flow guide pipes).

[0043] In an optional embodiment of the utility model, the clamping arm 30 is arranged on the upper side of the slot of the profiled groove 20. It is suitable for the structure that the end of the flat tube is upwardly protruded (such as the flange design at the end of part of the liquid cooling pipe), and the clamping arm 30 can accurately cover the protruded part by pressing from top to bottom.

[0044] As shown in the figure, Figure 4 The clamping arm 30 includes a telescopic part 31, and a lever 33 is arranged on the telescopic part 31. The telescopic part 31 is configured to block or avoid the slot of the profiled groove 20. The telescopic part 31 changes the effective clamping range of the clamping arm 30 by telescopic action, forms a closed clamping space in the "blocking slot" state to prevent the flat tube from falling out, and completely opens the slot in the "avoiding slot" state to facilitate the quick taking and placing of the flat tube. For flat tubes of different widths (such as single-layer thin-walled tubes and multi-layer composite tubes), the telescopic part 31 can adjust the clamping coverage area to avoid clamping failure caused by too wide slot. In the flat tube pre-assembly stage, the telescopic part 31 is retracted to avoid the slot, which facilitates the accurate pushing of the flat tube into the profiled groove 20 by the mechanical arm.

[0045] As shown in the figure, Figure 3 , 4As shown, the clamping arm 30 is equipped with a knob 32 for driving the telescopic part 31 to move along a first direction. The first direction corresponds to the thickness direction of the battery cooling flat tube 1. By rotating the knob 32, the telescopic part 31 is driven to move along the thickness direction of the flat tube, realizing stepless adjustment of the clamping force and ensuring stable clamping of flat tubes of different thicknesses. When flat tubes of different thicknesses are produced on the same production line (such as conventional heat dissipation tubes and reinforced explosion-proof tubes), the operator can quickly adjust the position of the clamping arm 30 through the knob 32. During maintenance or debugging, the position of the clamping arm 30 can be manually fine-tuned to compensate for clamping gap deviations caused by tooling wear. The knob 32 is intuitive and easy to operate, reducing worker training costs. Adjustment along the thickness direction can accurately match the actual size of the flat tube, avoiding tube deformation due to excessive clamping or clamping failure due to excessive looseness. The mechanical adjustment mechanism has high reliability and does not rely on an external power source, making it suitable for special environments such as cleanrooms.

[0046] The knob 32 can be connected to a screw, and the telescopic part 31 has a threaded hole (or is connected via a nut pair). When the knob 32 is rotated, the screw is screwed into / out of the threaded hole, converting the rotational motion into the linear movement of the telescopic part 31.

[0047] The knob 32 can also have a fixed pinion at its shaft end, and a rack is provided on the side of the telescopic part 31, with the gear meshing with the rack. When the knob 32 is rotated, the gear drives the rack to move in a straight line (first direction), thereby pushing the telescopic part 31 to extend or retract.

[0048] like Figure 3 , 4 As shown, the surface of the telescopic part 31 and / or the interior of the contouring groove 20 are covered with a buffer layer. The elastic buffer layer (such as rubber or silicone) covering the surface of the telescopic part 31 or the interior of the contouring groove 20 absorbs impact energy through deformation and increases the coefficient of friction, achieving damage-free clamping of the flat tube. When handling flat tubes with surface coatings or anodized finishes, the buffer layer prevents coating peeling caused by direct contact between hard metal and tooling. In high-speed transport scenarios, the buffer layer offsets inertial impacts through deformation, preventing rigid collisions between the flat tube and tooling. It eliminates surface defects such as scratches and indentations during clamping, meeting the requirements of high-cleanliness production lines. The buffer layer absorbs vibration energy generated by the start-up and shutdown of the conveyor mechanism or path bumps, reducing the fatigue risk of the flat tube structure. The elastic material adaptively fills the tiny gaps between the flat tube and the tooling, maintaining uniform force even with dimensional tolerances.

[0049] In an optional embodiment of this utility model, rollers are provided on the surface of the tooling base plate 10 away from the contour groove 20. Providing rollers on the side of the tooling base plate 10 away from the contour groove 20 allows the tooling to slide freely on a flat surface (such as a workshop floor or conveyor belt platform), reducing resistance from manual or equipment pushing. After the conveying mechanism (such as a crane) lifts the tooling to the target area, the operator can gently push the tooling base plate 10 and use the rollers to precisely position it at the assembly station. In small workshops without suspension equipment, the rollers can be used to directly push the tooling for batch transfer of flat tubes. The rollers reduce friction between the tooling and the contact surface, avoiding the physical exertion of manual handling of the tooling. The rollers are suitable for smooth surfaces (such as epoxy flooring) or production lines with guide rails, improving the flexibility of tooling deployment, avoiding mechanical wear caused by frequent fine-tuning of the lifting mechanism, and extending the life of the conveying equipment.

[0050] like Figure 3 , 4 As shown, a handle 11 is provided on the side of the tooling base plate 10 where the contour groove 20 is located. The handle 11 provides a fulcrum for the operator, facilitating manual adjustment of the tooling position or assisting in stabilizing the clamping process. During the assembly of the flat tube and the battery module, the worker can use the handle 11 to fine-tune the tooling angle, ensuring precise contact between the flat tube and the module's heat dissipation surface. In case of automated equipment failure, the worker can manually drag the tooling away from the production line using the handle 11, avoiding production interruption. The handle 11 serves as a human-machine interface, balancing automated processes with manual intervention needs, thus improving system fault tolerance. When applying force by gripping the handle 11, the worker's hand is kept away from the clamping area, reducing the risk of accidental contact with the clamping mechanism. The position of the handle 11 indicates the tooling's center of gravity distribution, guiding the worker to push or lift the tooling in a less strenuous manner.

[0051] This utility model also proposes a battery cooling flat tube transfer system, including a conveying unit and the aforementioned transfer fixture.

[0052] In summary, the inclusive contact design of the contouring groove 20 and the buffer layer in this invention avoids surface scratches, coating peeling, and stress concentration damage to the flat tube, ensuring the integrity of the thin-walled, fragile material. The dual fixing mechanism of the segmented contouring groove 20 and the clamping arm 30 effectively prevents accidental slippage of the flat tube under suspension, vibration, or tilting conditions. The tooling base plate 10 is directly connected to the conveying mechanism (such as a robotic arm or AGV) to achieve unmanned gripping and release, matching the needs of high-speed production lines. The parallel layout of multiple contouring grooves 20 and the independent clamping arm 30 design support the synchronous transfer of multiple flat tubes, significantly shortening batch processing time. Suspended transfer replaces manual gripping, eliminating the risk of scratches caused by workers coming into contact with sharp edges. The mechanical locking mechanism between the clamping arm 30 and the telescopic part 31 prevents safety accidents caused by flat tube slippage or inertial swinging. Through the adjustment of the telescopic part 31, the drive of the knob 32, and the adjustable spacing of the contouring grooves 20, it adapts to flat tubes of different thicknesses, widths, and arrangement patterns. The contoured groove 20 matches the shape of the horizontal tube 2 at the end of the flat tube, and combined with gravity-assisted alignment, ensures the repeatability of the handling posture for each transport, guaranteeing the quality of subsequent assembly. The roller and handle 11 design supports seamless switching between automated and manual intervention modes for the tooling, adapting to complex workshop environments. The modular structure (such as replaceable buffer layers and telescopic parts 31) simplifies the tooling adjustment process and shortens production line changeover time.
