In the complex system of new energy vehicles, the power battery undoubtedly occupies a core position. As a key component for building electrical connections between battery cells, the bending and forming quality of the battery tabs directly affects the conductivity, stability and safety of the battery pack.

[0003] The existing bending device can only bend one connecting piece at a time. After bending one connecting piece, it is removed from the device and a new connecting piece to be processed is placed. However, the bending device is in a stopped state during the replacement process, which reduces production efficiency.

[0004] Therefore, those skilled in the art have provided a device for bending and forming the tabs of a power battery connector to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By installing the switching component, the workstation of the connecting piece can be switched. Multiple connecting pieces can be placed at one time. After one connecting piece is bent, there is no need to stop the machine to remove it and place a new connecting piece to be processed. By rotating the placement plate, the next connecting piece to be processed can be moved to the bending position. While bending, the operator can remove the bent connecting piece from the corresponding placement plate and place the new connecting piece to be processed on the empty placement plate. This greatly saves the time spent changing connecting pieces, realizes cyclic processing, and significantly improves production efficiency.

[0015] 2. The placement slot is adapted to the shape of the power battery connecting piece and has anti-slip texture, which can initially fix the connecting piece; rotating the screw block drives the adjusting screw to rotate, so that the adjusting block moves along the axis of the adjusting screw, which in turn drives the fixing plate and the pressing plate to move. By using the arc surface of the bottom surface of the pressing plate to contact the surface of the connecting piece, the connecting piece can be further pressed and fixed in the placement slot, thus realizing a stable and reliable fixation of the power battery connecting piece.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figure 1 - Figure 5This embodiment provides a power battery connector tab bending and forming device, including a processing table 1. A switching component 2 is provided at the bottom of the inner wall of the processing table 1. The switching component 2 includes a servo motor 201, which is fixedly connected to the bottom of the inner wall of the processing table 1. A first transmission wheel 202 is fixedly connected to the transmission end of the servo motor 201. A transmission belt 203 is drivenly connected to the side surface of the first transmission wheel 202. A second transmission wheel 204 is drivenly connected inside the transmission belt 203. The first transmission wheel 202 is drivenly connected to the second transmission wheel 204 through the transmission belt 203. A support is fixedly connected inside the second transmission wheel 204. A rod 205 is fixedly connected to a fixed plate 206 at its top. A connecting plate 207 is fixedly connected to one side of the fixed plate 206. A placement plate 208 is fixedly connected to one side of the connecting plate 207. A placement groove 209 is formed at the top of the placement plate 208. A groove 3 is formed inside the placement plate 208. A rotating hole 4 is formed at the top of the inner wall of the groove 3. An adjusting screw 5 is rotatably connected inside the rotating hole 4. A rotating block 6 is fixedly connected to the top of the adjusting screw 5. An adjusting block 7 is threaded onto the side surface of the adjusting screw 5. A fixed plate 8 is fixedly connected to the other side of the adjusting block 7. A pressing plate 9 is fixedly connected to the bottom of the fixed plate 8. The battery connecting piece is placed in the placement groove 209 on the top of the placement plate 208. Since the shape of the placement groove 209 matches the shape of the power battery connecting piece and has anti-slip texture, it can initially fix the connecting piece. Rotating the rotating block 6 causes the adjusting screw 5 to rotate within the rotating hole 4. When the adjusting screw 5 rotates, the adjusting block 7 moves along the axial direction of the adjusting screw 5 within the groove 3. The movement of the adjusting block 7 causes the fixing plate 8 and the pressing plate 9 to move. The bottom surface of the pressing plate 9 is an arc-shaped surface that contacts the surface of the power battery connecting piece, ultimately pressing and fixing the connecting piece in the placement groove 209. The servo motor 201 is then started, and the servo motor 201's transmission... The first drive wheel 202 rotates, and the first drive wheel 202 drives the second drive wheel 204 to rotate via the drive belt 203. Since the diameter of the second drive wheel 204 is larger than that of the first drive wheel 202, it can achieve a certain speed reduction and torque increase effect. When the second drive wheel 204 rotates, it drives the support rod 205 fixedly connected inside to rotate. The fixed plate 206 at the top of the support rod 205 rotates accordingly. The five connecting plates 207 fixedly connected to one side of the fixed plate 206 in a circular array and the five placement plates 208 fixedly connected to one side of the connecting plate 207 in a circular array also rotate together, thereby realizing the switching of the connecting plate's work position.

[0025] Example 2

[0026] Reference Figure 1 - Figure 5This embodiment is based on the previous embodiment, but differs in that a support frame 10 is fixedly connected to the top of the processing table 1, a hydraulic cylinder 11 is fixedly connected to the top of the inner wall of the support frame 10, a push rod 12 is fixedly connected to the output end of the hydraulic cylinder 11, a bending pressure plate 13 is fixedly connected to the bottom of the push rod 12, the diameter of the second transmission wheel 204 is larger than the diameter of the first transmission wheel 202, five connecting plates 207 are arranged in a circular array, five placement plates 208 are arranged in a circular array, the shape of the placement plates 208 is L-shaped, the shape of the placement groove 209 is adapted to the shape of the power battery connecting piece, and the placement groove 209 is provided with anti-slip texture, the adjusting block 7 is provided with internal thread and is adapted to the adjusting screw 5 for pressing. The bottom surface of plate 9 is an arc-shaped surface that contacts the surface of the power battery connecting piece. When the placement plate 208, on which the connecting piece to be processed is placed, rotates to the appropriate position, the hydraulic cylinder 11 is activated. The output end of the hydraulic cylinder 11 pushes the push rod 12 downward, and the bending pressure plate 13, which is fixedly connected to the bottom of the push rod 12, moves downward accordingly. The power battery connecting piece tab, which is placed in the placement groove 209 and has been pressed, is bent until the required bending shape is achieved. After completing one bending operation, the hydraulic cylinder 11 drives the push rod 12 and the bending pressure plate 13 to rise and reset. The servo motor 201 is started again, driving the placement plate 208 to rotate, and the next placement plate 208 on which the connecting piece to be processed is rotated to the underside of the bending pressure plate 13. The above bending operation is repeated to achieve cyclic processing.
