DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] Current battery welding equipment is usually only capable of welding one side of a battery. If welding on both sides of a battery is required, the following two common methods are usually used.

[0033] The first method involves manual intervention after completing welding on one side of the battery. This involves removing the battery from the fixture and adjusting its position to fix it in the opposite direction for welding on the other side. However, this method is not only time-consuming but also increases labor intensity, resulting in low overall welding efficiency.

[0034] The second method is used in a fully automated production line environment. After completing the welding of one end of the battery cell, the welding of the other end of the battery cell is continued in the subsequent production link through the conversion of the process flow. Although this method is more suitable for large-scale production needs, its higher initial investment and operating costs become a significant disadvantage.

[0035] Based on the above problems, an embodiment of the present invention provides a battery welding tool, which can assist in welding small batches of cylindrical battery cells; the tool has the advantages of simple process, low operating cost, easy disassembly, simplicity and practicality.

[0036] For details, see Figures 1 to 3 The battery welding tool 10 includes a base 100 , a welding part 200 and a first driving part 300 .

[0037] Among them, the welding part 200 is rotatably arranged on the base 100, the welding part 200 is used to install the battery cell 20, and welding holes 210 are provided on both sides of the welding part 200, and the welding holes 210 are used to expose the ends of the battery cell 20; the first driving part 300 is arranged on the base 100 and is transmission-connected to the welding part 200, and the first driving part 300 is used to drive the welding part 200 to rotate.

[0038] In this embodiment, multiple battery cells 20 can be installed on the welding part 200, and the welding part 200 is driven to rotate by the first driving part 300 so that one side of the welding part 200 is rotated to the welding position, thereby facilitating the welding device to weld the battery cells 20 through the welding holes 210 on that side; and after the welding on that side is completed, the welding part 200 is driven to rotate relative to the base 100 by the first driving part 300 so that the other side of the welding part 200 is rotated to the welding position, thereby facilitating the welding device to weld the battery cells 20 through the welding holes 210 on that side.

[0039] It can be seen that the battery welding tool 10 provided by the present invention can weld both sides of the battery cell 20 in sequence by rotating the direction of the welding part 200. It has a simple structure, is easy to install or disassemble, and has low cost of use. It can be suitable for the welding needs of small batches of battery cells 20.

[0040] Furthermore, the welding part 200 includes a connecting plate 220, a first welding plate 230 and a second welding plate 240. The first welding plate 230 and the second welding plate 240 are arranged at intervals and are both connected to the connecting plate 220. The first driving part 300 is connected to the connecting plate 220. The battery cell 20 is used to be arranged between the first welding plate 230 and the second welding plate 240. The first welding plate 230 and the second welding plate 240 are both provided with welding holes 210.

[0041] In this embodiment, the first welding plate 230 and the second welding plate 240 are arranged in parallel and at intervals, and a plurality of battery cells 20 can be arranged between the first welding plate 230 and the second welding plate 240; and the first welding plate 230 and the second welding plate 240 are connected by a connecting plate 220. Therefore, when the first driving member 300 drives the connecting plate 220 to rotate, the connecting plate 220 can drive the first welding plate 230 and the second welding plate 240 to rotate as a whole, thereby facilitating the welding of the battery cells 20 in the welding holes 210 of the first welding plate 230 and the battery cells 20 in the welding holes 210 of the second welding plate 240, respectively.

[0042] It can be understood that in the initial state, the first welding plate 230 and the second welding plate 240 are usually arranged horizontally, and the first welding plate 230 is located vertically above the second welding plate 240, so that the welding device can weld the battery cell 20 through the welding hole 210 of the first welding plate 230; after the welding is completed, the first driving member 300 drives the first welding plate 230 and the second welding plate 240 to rotate relative to the base 100, so that the first welding plate 230 is located vertically below the second welding plate 240, so that the welding device can weld the battery cell 20 through the welding hole 210 of the second welding plate 240, thereby achieving welding on both sides of the battery cell 20.

[0043] Optionally, the first driving member 300 is a rocker structure, so the operator can manually rotate the first driving member 300 to drive the first welding plate 230 and the second welding plate 240 to rotate; therefore, in actual application, by only rotating the first driving member 300°, the positions of the first welding plate 230 and the second welding plate 240 can be driven to convert with each other.

[0044] Furthermore, the battery welding tool 10 also includes a second driving member 400 and a mounting frame 500, the mounting frame 500 is connected to the second welding plate 240, the second driving member 400 is arranged on the mounting frame 500, and the second driving member 400 is connected to the first welding plate 230, and is used to drive the first welding plate 230 to move in a direction close to or away from the second welding plate 240.

[0045] In this embodiment, the first welding plate 230 is driven by the second driving member 400 to move away from the second welding plate 240 to facilitate the installation of multiple battery cells 20 on the second welding plate 240, and then the first welding plate 230 is driven by the second driving member 400 to move close to the second welding plate 240, so that the first welding plate 230 and the second welding plate 240 can jointly clamp and fix the multiple battery cells 20 to ensure that the battery cells 20 are stably installed.

[0046] Optionally, the second driving member 400 is threadably engaged with the mounting bracket 500 .

[0047] In this embodiment, the second driving member 400 is also a rocker structure. Therefore, the operator can manually rotate the second driving member 400 to drive the first welding plate 230 to move up and down in the vertical direction.

[0048] Of course, in other embodiments of the present invention, the first driving member 300 and the second driving member 400 can also be other structures or devices. For example, the first driving member 300 can be a motor, etc., and the second driving member 400 can be a cylinder, etc. No specific limitations are made here on the first driving member 300 and the second driving member 400.

[0049] Furthermore, the battery welding tool 10 also includes a guide rod 600, one end of the guide rod 600 is connected to the second welding plate 240, and the other end is connected to the mounting frame 500, and the first welding plate 230 is slidably matched with the guide rod 600.

[0050] In this embodiment, the guide rod 600 is arranged perpendicular to the first welding plate 230 and the second welding plate 240. Therefore, when the second driving member 400 drives the first welding plate 230 to move closer to or away from the second welding plate 240, it is ensured that the first welding plate 230 can move along the extension direction of the guide rod 600.

[0051] Optionally, a plurality of guide rods 600 may be provided.

[0052] Furthermore, the battery welding tool 10 also includes a first limiting member 700 , which is movably disposed on the connecting plate 220 . The first limiting member 700 is used to abut against the first welding plate 230 to limit the first welding plate 230 .

[0053] In this embodiment, a first limiting member 700 is provided on the connecting plate 220 so that when the first welding plate 230 and the second welding plate 240 press the battery cell 20, the first limiting member 700 abuts against the side of the first welding plate 230 away from the second welding plate 240, thereby ensuring that the first welding plate 230 tightly presses the battery cell 20.

[0054] Optionally, the first limiting member 700 and the connecting plate 220 are threadedly engaged.

[0055] Of course, in other embodiments of the present invention, the first limiting member 700 may also be other structures or devices. For example, the first limiting member 700 may be a motor or a cylinder, etc. The first limiting member 700 is not specifically limited here.

[0056] Furthermore, the first welding plate 230 is provided with multiple first mounting grooves 231, and the second welding plate 240 is provided with multiple second mounting grooves 241. The multiple first mounting grooves 231 and the multiple second mounting grooves 241 are arranged one by one opposite to each other, and the welding holes 210 are arranged on the bottom walls of the multiple first mounting grooves 231 and the multiple second mounting grooves 241.

[0057] Furthermore, the battery welding tool 10 also includes a second limiting member 800 , which is movably disposed on the base 100 . The second limiting member 800 is used to abut against the welding member 200 to limit the welding member 200 .

[0058] In this embodiment, since the first welding plate 230 and the second welding plate 240 are both rotated by the first driving member 300, it may not be possible to accurately make the first welding plate 230 and the second welding plate 240 finally in a horizontal state during the rotation process. Therefore, a second limiting member 800 is provided to make the second limiting member 800 abut against the first welding plate 230 or the second welding plate 240 when the first welding plate 230 and the second welding plate 240 are rotated to a horizontal state, thereby effectively playing a limiting role.

[0059] Furthermore, the base 100 includes a bottom plate 110 and a mounting rod 120 , and the second limiting member 800 is threadedly engaged with the mounting rod 120 .

[0060] In this embodiment, the second limiting member 800 can be extended to abut against the second welding plate 240 or retracted to detach from the second welding plate 240 by turning the second limiting member 800 .

[0061] Optionally, the second limiting member 800 and the connecting plate 220 are also threadedly engaged.

[0062] Of course, in other embodiments of the present invention, the second limiting member 800 may also be other structures or devices. For example, the second limiting member 800 may be a motor or a cylinder, etc. The second limiting member 800 is not specifically limited here.

[0063] Furthermore, the base 100 includes a bottom plate 110 and two mounting columns 130 , the two mounting columns 130 are provided on the bottom plate 110 , the welding member 200 is rotatably provided between the two mounting columns 130 , and the driving member is provided on one of the mounting columns 130 and connected to the welding member 200 .

[0064] In this embodiment, the number of connecting plates 220 is also two, and the two connecting plates 220 are respectively arranged at the two ends of the first welding plate 230 and the second welding plate 240. One of the connecting plates 220 is rotatably arranged on the mounting column 130, and the other connecting plate 220 is connected to the first driving member 300.

[0065] In summary, the present invention provides a battery welding tool 10, wherein a plurality of battery cells 20 can be mounted on a welding member 200, and the welding member 200 is driven to rotate by a first driving member 300 so that one side of the welding member 200 rotates to a welding position, thereby facilitating the welding device to weld the battery cells 20 through the welding holes 210 on that side; and after the welding on that side is completed, the welding member 200 is driven to rotate relative to the base 100 by the first driving member 300 so that the other side of the welding member 200 rotates to a welding position, thereby facilitating the welding device to weld the battery cells 20 through the welding holes 210 on that side. It can be seen that the battery welding tool 10 provided by the present invention can realize the sequential welding of both sides of the battery cell 20 by rotating the direction of the welding member 200, has a simple structure, is easy to install or disassemble, and has a low cost of use, and can be applied to the welding needs of small batches of battery cells 20.
