[0016] like Figure 1 As shown, the processing method includes: S11, making a plurality of first battery springs: controlling the first die of the first stamping mechanism to press downward, processing the metal sheet into a flat sheet of a preset shape, and punching out a first positioning mark and a second positioning mark and a contact portion adapted to the positive electrode tab of the cylindrical battery on the flat sheet; controlling the manipulator welding mechanism to weld one end of the first spring to a first target position corresponding to the first positioning mark, and to weld the second deformed portion to a second target position corresponding to the second positioning mark; controlling the bending mechanism to process one end of the flat sheet into a U-shaped spring to form a first deformed portion, wherein the other end of the first spring abuts against the inner side surface of the U, and the first contact portion is located on the outer side surface of the U corresponding to the abutting position; S12, manufacturing a second battery spring piece and a third battery spring piece: controlling the second die of the second stamping mechanism to press downward, cutting the connection between the positive electrode spring piece and the negative electrode spring piece of the first battery spring piece to obtain the second battery spring piece and the third battery spring piece; S13, assembling the battery box: controlling the robot arm to clamp the first battery spring clip into one side of the box body, and clamp the second battery spring clip and the third battery spring clip into the other side of the box body.

[0017] In this embodiment, the positive electrode spring sheet is composed of a first spring, a U-shaped spring sheet and a contact portion, so that the positive electrode spring sheet has the stability of a spring and can also be deformed when the battery is replaced. The negative electrode spring sheet is composed of a second spring, a spring cap, a fixing column and a limiting shell. The fixing column and the limiting shell can ensure the directional deformation of the second spring, and the inclined surface of the spring cap can serve as a guide surface when disassembling the battery, thereby ensuring smooth disassembly of the battery and improving the convenience of battery replacement. At the same time, the first stamping mechanism cooperates with the robot welding mechanism to realize the automated production of the first battery spring sheet, the second stamping mechanism realizes the automated production of the second and third battery spring sheets, and the robot realizes the automated assembly of the battery box. The entire process realizes automated production, thereby improving production efficiency. Compared with the traditional battery box production method, only an additional bending mechanism is required to avoid high equipment costs caused by process changes.

[0018] In some embodiments, the first mold includes an upper mold and a cutting blade designed around the upper mold, the contour of the cutting blade being the preset shape; the upper mold is movably connected to the cutting blade, the first mold of the first stamping mechanism is pressed downward to process the metal sheet into a flat sheet of the preset shape, and a first positioning mark and a second positioning mark and a contact portion adapted to the positive electrode tab of the cylindrical battery are stamped out of the flat sheet, including: Transferring the metal sheet to a first workbench of a first punching mechanism, wherein the first workbench is provided with a cutting groove adapted to the cutting knife and a lower die adapted to the upper die, wherein the groove depth of the cutting groove is no greater than the blade height of the cutting knife; Controlling the cutting blade to press down to the cutting groove to cut the metal sheet into a flat sheet of a preset shape; The cutting knife is controlled to be reset, and the upper die is controlled to be pressed down until the clamping pressure with the lower die reaches a preset pressure value, the first positioning mark, the second positioning mark and the contact part of the flat plate are punched out, and then the upper die is controlled to be reset.

[0019] In this embodiment, when the cutting blade cuts the flat plate, the plate may become embedded in the inner cavity formed by the cutting blade, making it impossible to remove the plate. Therefore, the upper mold presses down to separate the plate from the inner cavity formed by the cutting blade and press the plate to form the first positioning mark, the second positioning mark, and the contact portion. At the same time, the rest of the plate is pressed flatter. It should be understood that the contact portion is a three-dimensional structure on two surfaces of the flat plate.

[0020] In some embodiments, the controlling the manipulator welding mechanism to weld one end of the first spring to a first target position corresponding to the first positioning mark, and to weld the second deformable portion to a second target position corresponding to the second positioning mark, comprises: Identifying a first target position corresponding to a first positioning mark on the flat plate by using an infrared camera, then controlling a robotic welding mechanism to grab the first spring and weld one end of the first spring to the first target position on the flat plate; Identifying a second target position corresponding to a second positioning mark of the flat plate by an infrared camera, then controlling a robotic welding mechanism to grab the second deformed portion and weld the second deformed portion to the second target position corresponding to the second positioning mark; During the welding process, the welding temperature is identified by the infrared camera, and the welding coordinates of the manipulator welding mechanism are dynamically adjusted based on the welding temperature.

[0021] In this embodiment, the infrared camera can eliminate the influence of metal reflection when identifying the first and second positioning marks, thereby improving recognition accuracy. Furthermore, the infrared camera can sense the welding temperature, eliminating the need for additional temperature sensing components. Optionally, when the temperature of a welding coordinate reaches a preset temperature, the robotic welding mechanism indicates that the weld is in place, and the robotic welding mechanism is adjusted to the next welding coordinate for welding.

[0022] In some embodiments, the limiting shell is provided with openings at both ends, and a limiting ring is provided at one end of the opening. The fixing column, the second spring and the spring cap are provided in the inner cavity of the limiting shell. The cap body of the spring cap passes through the opening of the limiting block, and the cap edge of the spring cap abuts against the limiting ring. One end of the second spring is sleeved on the fixing column and abuts against the base of the fixing column, and the other end of the second spring is fixedly connected to the spring cap. The control manipulator welding mechanism grabs the second deformation part and welds the second deformation part to the second target position corresponding to the second positioning mark, including: Identifying the inclined surface of the spring cap, controlling the robot welding mechanism to grasp the second deformed portion, and placing the second deformed portion at a second target position of the flat plate in a preset posture; The robot welding mechanism is controlled to weld the second deformation portion.

[0023] In this embodiment, in order to make it easier for users to replace the battery, the user can slightly tilt one end of the battery and then remove it smoothly along the slope of the spring cap. To this end, the slope of the spring cap needs to face upward (i.e. away from the bottom of the battery box), so the posture of the second deformation part needs to be determined when welding the spring cap. It should be noted that the second deformation part can be pre-installed as a whole, and its specific structure can be as follows Figure 3 As shown, it can be provided by the supplier.

[0024] In some embodiments, the controlled bending mechanism processes one end of the planar plate into a U-shaped spring piece to form a first deformation portion, including: Controlling the bending mechanism to quickly bend one end of the planar plate at a first preset angle and a first rotation speed, and then controlling the bending mechanism to reset to a second preset angle; The bending mechanism is controlled to slowly bend one end of the planar plate at a third preset angle and a second rotational speed, so as to process one end of the planar plate into a U-shaped spring piece to form the first deformation portion, and the first rotational speed is greater than the second rotational speed.

[0025] In this embodiment, fast bending can quickly pre-form the elastic deformation area of the U-shaped spring piece, and the resetting of the bending mechanism to the second preset angle can compensate for the rebound of the U-shaped spring piece to ensure bending accuracy; slow bending ensures that the R angle tolerance of the U-shaped bottom is within the preset error range.

[0026] In some embodiments, the second mold includes a double cutting knife with parallel blades, and the second mold controlling the second punching mechanism is pressed downward to cut the connection between the positive electrode spring piece and the negative electrode spring piece of the first battery spring piece to obtain the second battery spring piece and the third battery spring piece, including: Placing the first battery spring piece on the second workbench of the second stamping mechanism, wherein the second workbench is provided with a limit block for positioning the first battery spring piece; The double cutting blades of the second mold are controlled to press down to cut the first battery shrapnel to separate the positive and negative shrapnel of the first battery shrapnel. The separated positive shrapnel serves as the second battery shrapnel, and the separated negative shrapnel serves as the third battery shrapnel.

[0027] In this embodiment, the connection portion of the positive and negative electrode springs can be cut off at one time by using the double cutting knife, thereby quickly obtaining the second and third battery springs; the limiting block can ensure the accuracy of the cutting position.

[0028] In some embodiments, a first card slot is provided on an inner wall of one side of the box body, and a second card slot and a third card slot are provided on an inner wall of the other side of the box body, and the notches of the first card slot, the second card slot, and the third card slot are all provided with guiding inclined surfaces; the control manipulator clamps the first battery spring into one side of the box body and clamps the second battery spring and the third battery spring into the other side of the box body, including: Control the manipulator to grab the first battery spring clip, and insert the first battery spring clip into the first card slot with an interference fit until the insertion pressure reaches a preset value; control the manipulator to grab the second battery spring clip, and insert the second battery spring clip into the second card slot with an interference fit until the insertion pressure reaches a preset value; control the manipulator to grab the third battery spring clip, and insert the third battery spring clip into the third card slot with an interference fit until the insertion pressure reaches a preset value.
