Please refer to Figures 1 to 5, a shaping tool for battery side seam welding includes a frame 1, a positioning fixture 2 and a shaping mechanism 3, wherein: the positioning fixture 2 is installed on the frame 1, and the positioning fixture 2 is used to assemble batteries; the shaping mechanism 3 is installed on the frame 1, and two shaping mechanisms 3 are mirror-imaged on both sides of the positioning fixture 2; the shaping mechanism 3 includes an extension component and a pressure head component 35, the extension component includes at least two, the extension directions of the extension components are consistent and connected in series in sequence, the pressure head component 35 is installed at the end of the extension component, and the extension components of the two shaping mechanisms 3 can extend toward each other. By arranging the shaping mechanism 3 on both sides of the positioning fixture 2, the shaping mechanism 3 can be compressed in volume by extending the action of the component when the robot arm is loading and unloading the battery to free up the space above the positioning fixture 2. Compared with the traditional gantry structure, in this embodiment, two shaping mechanisms 3 are arranged on both sides of the positioning fixture 2 to achieve rapid movement of the space above the positioning fixture 2. Specifically, compared with a single gantry structure, the shaping mechanism 3 has a shorter stroke to free up space. Therefore, at the same displacement speed, the shaping mechanism 3 in this embodiment takes less time, which is beneficial to improving production and processing efficiency. At the same time, the extension component facilitates the adjustment of the position of the pressure head assembly 35, so that the shaping tool for battery side seam welding can adapt to the processing of batteries of different models.

In this embodiment, a first plug-in structure 34 is provided on one of the shaping mechanisms 3, and a second plug-in structure 30 adapted to the first plug-in structure 34 is provided on the other shaping mechanism 3; when the extension components of the two shaping mechanisms 3 extend toward each other to the end position, the first plug-in structure 34 is plugged with the second plug-in structure 30. When in use, after the extension components of the two shaping mechanisms 3 extend toward each other so that the pressure head assembly 35 corresponds to the battery component, the first plug-in structure 34 cooperates with the second plug-in structure 30 so that the two shaping mechanisms 3 on both sides of the positioning fixture 2 form a whole, thereby improving the structural strength of the shaping tooling for battery side seam welding. It should be noted that the end position of the extension components extending toward each other depends on the battery model, and the pressure head assembly 35 reaches the corresponding battery position. At this time, the first plug-in structure 34 and the second plug-in structure 30 can be plugged and matched.

Optionally, the first plug-in structure 34 is a pin shaft, and the second plug-in structure 30 is a pin hole. Specifically, when in use, the pin shaft corresponds to the pin hole, and when the shaping mechanism 3 reaches the end position, the pin shaft is inserted into the pin hole.

As shown in FIG2 , the first plug-in structure 34 and the second plug-in structure 30 are correspondingly arranged on the extension assembly. Specifically, a first guide rail connecting plate 31 is arranged on the extension assembly of one of the shaping mechanisms 3, a guide groove 33 is arranged on the first guide rail connecting plate 31, the first plug-in structure 34 is slidably installed in the guide groove 33, and a third driving member 37 for driving the first plug-in structure 34 to slide in the guide groove 33 is arranged on the extension assembly. In this way, the position of the first plug-in structure 34 is adjustable, so that the relative position between the first plug-in structure 34 and the second plug-in structure 30 can be actively adjusted to cooperate with the extension assembly to adapt to the processing requirements of more types of batteries.

Furthermore, a first upper cover plate 32 is further included, and the first upper cover plate 32 is arranged on the first guide rail connecting plate 31, and is used to cover the guide groove 33. Here, the first upper cover plate 32 is used to cooperate with the guide groove 33 to limit the first plug-in structure 34 in the circumferential direction, and at the same time, it can prevent impurities from entering the guide groove 33 and affecting the sliding of the first plug-in structure 34 in the guide groove 33.

The second plug-in structure 30 may be a hole provided on the extension component. It may also be, as shown in FIG. 2 , specifically a second guide rail connecting plate 38 provided on the extension component of another shaping mechanism 3 corresponding to the first plug-in structure 34, a second upper cover plate 39 provided on the second guide rail connecting plate 38, and a hole structure for accommodating the first plug-in structure 34 is formed between the second guide rail connecting plate 38 and the second upper cover plate 39. Furthermore, a groove structure is provided on the second guide rail connecting plate 38 and/or the second upper cover plate 39. The groove structure is used to form a hole structure.

As shown in FIG3 , it also includes a seat plate 36, which is mounted on the frame 1, and an extension assembly is mounted on the seat plate 36; the extension assembly includes a first driving member 361, a slider 362 and a slide rail 363, the first driving member 361 is mounted on the seat plate 36, the slide rail 363 or the slider 362 is mounted on the seat plate 36, and the slider 362 is slidably connected to the slide rail 363. In this embodiment, when the slide rail 363 is mounted on the seat plate 36, the first driving member 361 drives the slider 362 to slide relative to the slide rail 363, and the driving member of the extension assembly connected in series with the extension assembly is mounted on the slider 362; when the slider 362 is mounted on the seat plate 36, the first driving member 361 drives the slide rail 363 to slide relative to the slider 362, and the driving member of the extension assembly connected in series with the extension assembly is mounted on the slide rail 363. In this way, the extension assembly can be adjusted in the extension direction. By connecting at least two extension components in series, the adjustment range of the shaping mechanism 3 can be increased. At the same time, when it is necessary to free up space above the positioning fixture 2, the volume of the shaping structure can be compressed as much as possible to avoid interference between the shaping mechanism 3 and the robotic arms used for loading and unloading.

In this embodiment, optionally, the first plug-in structure 34 and the second plug-in structure 30 are respectively located on the most distal extension components of their corresponding shaping mechanisms 3 .

Of course, when the extension components are connected in series, a plate transition can be used. For example, it is defined that three extension components are connected in series in sequence, the first extension component is installed on the mounting plate 353, and the slider 362 of the first extension component is driven by the driving member to slide relative to the slide rail 363. In order to install the second extension component, a plate 353 material can be installed on the slider 362, and the plate can serve as the aforementioned mounting plate 353, then the driving member and the slide rail 363 of the second extension component are installed on the plate, and the assembly method of the third extension component on the second extension component is the same as the assembly method of the second extension component on the first extension component.

Further, as shown in FIGS. 3 to 5 , the pressure head assembly 35 includes a support plate 350, a second driving member 352, a mounting plate 353 and a rolling wheel 351, wherein: the support plate 350 is mounted on the most terminal extension assembly, the fixed end of the second driving member 352 is mounted on the support plate 350, and the mounting plate 353 is mounted on the telescopic end of the second driving member 352; the rolling wheel 351 is mounted on the mounting plate 353 for shaping the battery. When in use, when the pressure head assembly 35 follows the extension assembly to reach the aforementioned key position, the second driving member 352 drives the support plate 350 to move downward from top to bottom, thereby pressing and fixing the battery from top to bottom through the rolling wheel 351. The use of the rolling wheel 351 here can avoid the relative movement tendency between the pressure head assembly 35 and the battery in the left and right directions when the two are in contact, and the structural parts of the battery fixed by the pressure head assembly 35 are stable in the left and right directions, which can avoid the generation of cold welding during welding.

As shown in Figure 5, the support plate 350 includes a first plate 3501, a second plate 3502 and a third plate 3503 stacked in sequence, wherein the third plate 3503 is penetrated by a stepped hole 3504, a wheel frame 3511 is installed in the stepped hole 3504, the rolling wheel 351 is rotatably installed on the wheel frame 3511, the second plate 3502 is located between the first plate 3501 and the third plate 3503, and is used to cover the stepped hole 3504 on the upper side, and a buffer spring 3513 is arranged between the wheel frame 3511 and the second plate 3502, and the buffer spring 3513 acts on the wheel frame 3511 so that it has a movement tendency away from the second plate 3502. Here, the first plate 3501, the second plate 3502 and the third plate 3503 are stacked to facilitate the assembly of the wheel frame 3511. At the same time, the second plate 3502 covers the stepped hole 3504 to limit the buffer spring 3513, so that the rolling wheel 351 and the battery form a flexible contact to avoid crushing the battery. In this embodiment, a limiting step 3512 is provided on the wheel frame 3511 to adapt to the stepped hole 3504 to limit the wheel frame 3511.
