Description

Technical Field

[0001] This utility model relates to a conveying mechanism and a battery connector feeding device for battery connectors, belonging to the technical field of battery connector feeding. Background Technology

[0002] In the production of lithium battery modules, battery connectors are key components in the series connection of battery cells, and the accuracy of their welding positions directly affects the conductivity and safety of the module. Existing technologies often employ automated feeding equipment, such as a combination of a feeding mechanism, a conveying mechanism, and a picking mechanism, to achieve the feeding, conveying, and picking of connectors. Specifically, the feeding mechanism places the completed battery connectors onto the conveying mechanism, which then transports them to the picking position. The picking mechanism then retrieves and transfers the connectors to the welding station, thus achieving automated feeding of the battery connectors.

[0003] Typically, servo motors or cylinders are used to drive the conveyor mechanism to move the battery connectors to the correct position, enabling accurate transfer of the battery connectors between the feeding and picking positions. However, long-term use of servo motors or cylinders can lead to cumulative errors, causing inaccurate positioning of the feeding and picking positions. This results in the battery connectors shifting during welding, leading to poor welding and affecting battery safety performance. Utility Model Content

[0008] The positioning component includes a first positioning block, a second positioning block, and a positioning element disposed on the conveying platform. The positioning element is located between the first positioning block and the second positioning block. When the conveying platform moves to the material release position, the positioning element abuts against the first positioning block to limit the material release position. When the conveying platform moves to the material pick-up position, the positioning element abuts against the second positioning block to limit the material pick-up position.

[0009] As a further improvement of this utility model, the feeding platform is provided with at least one feeding trough for accommodating workpieces; when the feeding trough moves to the feeding position, the positioning member abuts against the first positioning block; when the feeding trough moves to the picking position, the positioning member abuts against the second positioning block; and the abutting position of the positioning member against the first positioning block is adjustable relative to the feeding trough along the conveying direction, and the abutting position of the positioning member against the second positioning block is adjustable relative to the feeding trough along the conveying direction.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model utilizes the abutting cooperation between the positioning component connected to the conveyor table and the first and second positioning blocks in the positioning assembly to achieve precise positioning of the conveyor table during movement. This ensures that the conveyor table can stop accurately when it reaches the feeding and picking positions, reducing positional errors and facilitating accurate feeding and picking operations.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0029] Example 1:

[0030] A conveying mechanism for feeding battery connectors is used to accurately transport battery connectors to a designated position during feeding. (Ref.) Figures 1-4 The device includes a conveying assembly and a positioning assembly for conveying battery connector pieces. The conveying assembly includes a base 11, a feeding platform 12 that is slidably disposed on the base 11 along the conveying direction and used to place the battery connector pieces, and a driver 13 for driving the feeding platform 12 to reciprocate. The positioning assembly includes a first positioning block 21, a second positioning block 22 that are spaced apart along the conveying direction, and a positioning member disposed on the feeding platform 12. The positioning member is located between the first positioning block 21 and the second positioning block 22. The positioning member abuts against the first positioning block 21 when the feeding platform 12 moves to the feeding position to limit the feeding position, and the positioning member abuts against the second positioning block 22 when the feeding platform 12 moves to the picking position to limit the picking position.

[0031] It should be noted that the feeding position refers to the position where the feeding mechanism places the battery connector piece on the conveyor table 12, and the picking position refers to the position where the picking mechanism removes the battery connector piece from the conveyor table 12, and the feeding and picking positions remain unchanged.

[0032] Meanwhile, to ensure the stable position of the battery connector on the conveying platform 12, at least one feeding slot 14 for accommodating the battery connector is provided on the top of the conveying platform 12. Since the position of the feeding slot must correspond to the feeding mechanism and the picking mechanism during feeding and picking, the feeding slot can be used to mark the feeding and picking positions. Thus, during feeding, when the feeding slot 14 moves to the feeding position, the positioning member abuts against the first positioning block 21, and the feeding mechanism places the battery connector in the feeding slot. During picking, when the feeding slot 14 moves to the picking position, the positioning member abuts against the second positioning block 22, and the picking mechanism removes the battery connector, thus achieving picking.

[0033] In this embodiment, refer to Figure 1 and Figure 2When the feeding chute 14 moves to the feeding and picking positions, the positioning components abut against the first positioning block 21 and the second positioning block 22 respectively, achieving precise positioning of the conveyor platform 12. The feeding and picking positions are thus determined, ensuring that the conveyor platform 12 stops accurately when it reaches the feeding and picking positions, avoiding positional errors and facilitating accurate feeding and picking operations. The driver 13 drives the conveyor platform 12 to reciprocate, enabling rapid and accurate switching between the feeding and picking positions, thus improving feeding efficiency and reliability. Furthermore, the structure is simple, occupies little space, and is low in cost.

[0034] Furthermore, under this structure, the driver 13 only needs to drive the conveyor table 12 to reciprocate along the conveying direction, which not only has a high degree of automation, but also simplifies the control of the driver 13.

[0035] In this embodiment, since the feeding position of the feeding slot 14 has been fixed, when the length of the battery connecting piece increases, it may be impossible to accurately put it into the feeding slot 14. At this time, it is necessary to replace the feeding slot 14 with one of different sizes to adapt to the change of the workpiece, which leads to increased equipment downtime and increased production costs. In this embodiment, the contact position between the positioning member and the first positioning block 21 is adjustable relative to the feeding trough 14 along the conveying direction, and the contact position between the positioning member and the second positioning block 22 is also adjustable relative to the feeding trough 14 along the conveying direction. Therefore, by adjusting the contact position between the positioning member and the first positioning block 21, the stopping position of the feeding trough 14 on the conveying platform 12 during feeding can be changed. By adjusting the contact position between the positioning member and the second positioning block 22, the stopping position of the feeding trough 14 on the conveying platform 12 during picking can be changed, thereby adjusting the travel of the conveying platform 12. Thus, while keeping the feeding and picking positions of the battery connecting piece unchanged, the position of the feeding trough 14 relative to the feeding and picking structures during feeding and picking can be adjusted by adjusting the contact position between the positioning member and the first positioning block 21 and the second positioning block 22, thereby adapting to battery connecting pieces of different lengths and avoiding hardware replacement due to changes in workpiece length.

[0036] Furthermore, currently, vacuum suction cups are commonly used as the material handling tool for battery connectors. The principle is to use vacuum negative pressure to create suction force to grasp the battery connector. Traditional vacuum suction cups have a fixed suction area. When the position of the battery connector placed in the feeding trough 14 changes relative to the vacuum suction cup, the effective contact area between it and the suction cup may decrease, resulting in insufficient suction force and making it prone to detachment or displacement. During the conveying process, the battery connector is subjected to mechanical vibration, causing its position in the feeding trough 14 to shift. This leads to a deviation in the relative position between the battery connector and the vacuum suction cup when the feeding trough moves to the material handling position, resulting in poor suction or suction displacement, affecting the final welding quality. In this embodiment, when the operator observes a shift in the position of the battery connector relative to the vacuum suction cup, the contact position between the positioning component and the second positioning block 22 can be adjusted to change the travel of the conveying platform 12. This, combined with the driver 13 driving the conveyor seat to move, adjusts the position of the battery connector relative to the vacuum suction cup, achieving stable suction of the battery connector by the vacuum suction cup.

[0037] Specifically, the positioning components include a first positioning part 23 for abutting against the first positioning block 21 and a second positioning block 22 for abutting against the second positioning part 24. The first positioning part 23 is positioned close to the first positioning block 21, and the second positioning part 24 is positioned close to the second positioning block 22. The conveying platform 12 is equipped with connecting parts 25 corresponding to both the first positioning part 23 and the second positioning part 24. The connecting parts 25 are elongated block-shaped structures. The first positioning part 23 is movably connected to the corresponding connecting part 25 to adjust the position of the first positioning part along the conveying direction, and the second positioning part 24 is movably connected to the corresponding connecting part 25 to adjust the position of the second positioning part 24 along the conveying direction. Therefore, by adjusting the positions of the first positioning part 23 and the second positioning part 24, the abutting positions of the first positioning block 21 and the first positioning part 23, as well as the abutting position of the second positioning block 22 against which the second positioning part 24 abuts, can be adjusted respectively. This adjusts the position of the feeding chute 13 during feeding and unloading, avoiding mutual interference and improving adjustment accuracy.

[0038] In this embodiment, both the first positioning part 23 and the second positioning part 24 are threadedly connected to their respective connecting parts 25. Specifically, the connecting parts 25 have threaded holes, and the outer surfaces of the first positioning part 23 and the second positioning part 24 have external threads that engage with the threaded holes on the connecting parts. On the one hand, the threaded connection allows for fine adjustments, improving the flexibility of the positional movement of the first positioning part 23 and the second positioning part 24. On the other hand, the threaded connection is relatively stable, preventing the first positioning part 23 and the second positioning part 24 from shifting due to vibration or impact, ensuring long-term stability. Furthermore, the first positioning part 23, the second positioning part 24, and the connecting parts 25 can also be adjusted using a slot and tooth engagement method. Simultaneously, the bolted connection facilitates the individual replacement of the first positioning part 23 and the second positioning part 24, making maintenance of the first positioning part 23 and the second positioning part 24 easier after long-term use, thereby improving the accuracy of the positional adjustment of the first positioning part 23 and the second positioning part 24.

[0039] In this embodiment, the conveying table 12 is provided with a mounting component 26, and two connecting components 25 are spaced apart on the mounting component 26 along the conveying direction, thereby integrating the first positioning part 23, the second positioning part 24 and the connecting piece on the mounting component, resulting in a compact structure and small space occupation. Furthermore, the mounting component 26 is detachably connected to the conveying table 12 by bolts, facilitating its replacement.

[0040] In this embodiment, the first positioning part 23 has a buffer layer at one end that abuts against the first positioning block 21, and the second positioning part 24 has a buffer layer at one end that abuts against the second positioning block 22. The buffer layer can be made of rubber or polyurethane material and covers the ends of the first positioning part 23 and the second positioning part 24. The buffer layer absorbs the impact force during contact, which can reduce noise and mechanical vibration. On the other hand, it reduces the deformation or wear caused by the hard contact between the first positioning block 21 and the second positioning block 22, thereby improving their service life.

[0041] In this embodiment, the driver 13 is configured as a telescopic cylinder or a telescopic hydraulic cylinder, which has a telescopic rod 131 capable of telescopic movement along the conveying direction. The telescopic end of the telescopic rod 131 is connected to the conveying platform, and the telescopic movement of the telescopic rod 131 can drive the conveying platform 12 to move.

[0042] In this embodiment, at least one slide rail 111 is provided on the top surface of the base 11, and at least one sliding member is provided on the bottom surface of the conveying platform 12 corresponding to each slide rail 111. The sliding member is slidably connected to the slide platform, and the slide rail 111 extends along the moving direction of the conveying platform 12. The sliding engagement of the slide rail 111 and the sliding member provides guidance for the movement of the conveying platform 12, which helps to improve the stability of the movement of the conveying platform 12. Furthermore, the sliding member is provided with a groove extending along the sliding direction, and the slide rail 111 is slidably embedded in the groove. The engagement of the slide rail 111 and the groove improves the stability of the sliding of the conveying platform 12.

[0043] Example 2:

[0044] A battery connector feeding device includes a conveying mechanism for feeding battery connectors as described in Embodiment 1 and a picking mechanism for picking up workpieces from the conveying assembly. The picking mechanism includes a lifting and lowering picking component and a drive assembly for driving the lifting and lowering movement of the picking component. The picking component has a vacuum suction port for picking up the workpiece. Here, the picking component is a vacuum suction cup, which uses negative pressure to pick up the workpiece. The bottom of the vacuum suction cup is provided with at least one vacuum suction port, which is located above the conveying platform 12. When the feeding trough 13 moves to the picking position, the drive assembly drives the picking component to descend to pick up the workpiece, and then rises to transfer it. In addition, the drive assembly includes a drive component, which may be a servo motor, and a transmission assembly in the form of a lever assembly. The output end of the motor, which serves as the drive component, is arranged downwards and connected to the picking component through the transmission assembly.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
