[0039] S13, assembling the battery box: controlling the manipulator to insert the first battery spring into one side of the box body, and inserting the second battery spring and the third battery spring into the other side of the box body.

[0040] In the embodiment, the positive spring is composed of the first spring, the U-shaped spring and the contact part, so that the positive spring has the stability of the spring and can also be deformed when the battery is replaced. The negative spring is composed of the second spring, the spring cap, the fixing column and the 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 the battery is disassembled, ensuring smooth disassembly of the battery and improving the convenience of replacing the battery. Meanwhile, the first battery spring is automatically produced by cooperation of the first stamping mechanism and the manipulator welding mechanism, the second battery spring and the third battery spring are automatically produced by the second stamping mechanism, and the battery box is automatically assembled by the manipulator. The whole process realizes automatic production, improves production efficiency, and compared with the traditional production method of the battery box, only a bending mechanism needs to be additionally added, avoiding high equipment cost caused by process change.

[0041] In some embodiments, the first die includes an upper die and a cutting knife designed around the upper die, the profile of the cutting knife being the preset shape; the upper die is movably connected with the cutting knife, and the first die of the first stamping mechanism is controlled to press down to process the metal plate into a planar plate with a preset shape, and a first positioning mark, a second positioning mark and a contact part adapted to the positive lug of the cylindrical battery are stamped out of the planar plate, including:

[0042] The metal plate is conveyed to the first workbench of the first stamping mechanism, the first workbench is provided with a cutting groove matched with the cutting knife and a lower die matched with the upper die, and the groove depth of the cutting groove is not greater than the blade height of the cutting knife;

[0043] The cutting knife is controlled to press down to the cutting groove to cut the metal plate into a planar plate with a preset shape;

[0044] The cutting knife is controlled to reset, and the upper die is controlled to press down to the closing pressure of the lower die to reach a preset pressure value, so that the first positioning mark, the second positioning mark and the contact part of the planar plate are stamped out, and then the upper die is controlled to reset.

[0045] In the embodiment, when the cutting knife cuts the planar sheet, the planar sheet can be embedded in the inner cavity formed by the cutting knife, and the planar sheet cannot be taken out. Therefore, the upper mold is pressed downward to make the planar sheet separate from the inner cavity formed by the cutting knife, and the planar sheet is pressed to form the first positioning mark, the second positioning mark and the contact part, and other positions of the planar sheet are pressed to be more flat. It should be understood that the contact part is a three-dimensional structure on two surfaces of the planar sheet.

[0046] In some embodiments, the control of the mechanical hand welding mechanism welds one end of the first spring to the first target position corresponding to the first positioning mark, and welds the second deformation part to the second target position corresponding to the second positioning mark, comprising:

[0047] The first target position corresponding to the first positioning mark of the planar sheet is identified by the infrared camera, and then the mechanical hand welding mechanism is controlled to grasp the first spring and weld one end of the first spring to the first target position of the planar sheet;

[0048] The second target position corresponding to the second positioning mark of the planar sheet is identified by the infrared camera, and then the mechanical hand welding mechanism is controlled to grasp the second deformation part and weld the second deformation part to the second target position corresponding to the second positioning mark;

[0049] In the welding process, the welding temperature is identified by the infrared camera, and based on the welding temperature, the welding coordinates of the mechanical hand welding mechanism are dynamically adjusted.

[0050] In the embodiment, the identification of the first positioning mark and the second positioning mark by the infrared camera can eliminate the influence of metal reflection and improve the identification accuracy. At the same time, the welding temperature can be sensed by the infrared camera without the need for additional temperature sensing elements. Optionally, when the temperature of the mechanical hand welding mechanism at a certain welding coordinate reaches a preset temperature, it indicates that the welding is in place, so the mechanical hand welding mechanism is adjusted to the next welding coordinate for welding.

[0051] In some embodiments, the limiting shell is provided with two open ends, and one end is provided with a limiting ring. The fixed column, the second spring and the spring cap are arranged in the inner cavity of the limiting shell. The cap body of the spring cap passes through the opening of the limiting shell, the cap edge of the spring cap abuts against the limiting ring, one end of the second spring is sleeved on the fixed column and abuts against the base of the fixed column, and the other end of the second spring is fixedly connected with the spring cap.

[0052] Identifying the slope of the spring cap, controlling the welding mechanism of the robot arm to grab the second deformation part, and placing the second deformation part at the second target position of the flat panel with a preset posture;

[0053] Controlling the welding mechanism of the robot arm to weld the second deformation part.

[0054] In this embodiment, to facilitate the user to replace the battery, the user slightly tilts one end of the battery, and then the spring cap can be smoothly removed along the slope of the spring cap. Therefore, the slope of the spring cap needs to be 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 shown in Figure 3

[0055] In some embodiments, the control bending mechanism processes one end of the flat panel into a U-shaped spring piece to form a first deformation part, including:

[0058] In this embodiment, fast bending can quickly pre-form the elastic deformation region of the U-shaped spring piece, and the reset of the bending mechanism to the second preset angle can compensate for the springback of the U-shaped spring piece to ensure the bending accuracy; slow bending ensures that the R angle tolerance of the U-shaped bottom is within the preset error range.

[0059] In some embodiments, the second die includes double cutting knives with parallel blades, and the control of the second die of the second punching mechanism to press down cuts the connection between the positive spring piece and the negative spring piece of the first battery spring piece to obtain a second battery spring piece and a third battery spring piece, including:

[0062] In this embodiment, the connection between the positive and negative electrode springs can be cut off in one go using a dual-cutting blade, thereby quickly obtaining the second and third battery springs; the limiting block can ensure the accuracy of the cutting position.

[0063] In some embodiments, a first slot is provided on one inner wall of the box body, and a second and a third slot are provided on the other inner wall of the box body. The openings of the first, second, and third slots are all provided with guide bevels. The controlled robotic arm engages the first battery spring clip into one side of the box body and engages the second and third battery spring clips into the other side of the box body, including:

[0064] The robotic arm is controlled to grasp the first battery spring and press it into the first slot until the pressing pressure reaches a preset value; the robotic arm is controlled to grasp the second battery spring and press it into the second slot until the pressing pressure reaches a preset value; the robotic arm is controlled to grasp the third battery spring and press it into the third slot until the pressing pressure reaches a preset value.
