[0045] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 , Figure 2 As shown, it is a schematic diagram of the overall structure of the automatic production system of copper and aluminum foil strips of the utility model, which mainly includes a robot 1, an automatic cutting and sorting device for metal foil 2, a high-frequency spot welding machine 3, a discharging robot arm 4, a cooling device 5, a cooling water tank 6, and a power distribution control cabinet group 7.

[0047] Robot 1, please refer to Figure 3 , is a multi-degree-of-freedom industrial robot 11, with a clamping claw 12 installed at the end, which can grab the stacked metal foil. The robot 1 mainly clamps the sorted stacked metal foil from the discharge of the metal foil automatic cutting and sorting device 2, and then puts it on the welding table of the high-frequency spot welding machine 3 for welding; the robot 1 can generally rotate as a whole to realize the conversion of the workstation, so the robot 1 is located between the metal foil automatic cutting and sorting device 2 and the high-frequency spot welding machine 3; Figure 1 , Figure 2 The arc dotted line in the figure is the overall rotation working path of the robot 1; from the perspective of path planning, the robot 1, the metal foil automatic cutting and sorting device 2, and the high-frequency spot welder 3 form a triangular relationship, thereby shortening the overall rotation angle of the robot 1, improving the efficiency of material transfer, and avoiding the metal foil automatic cutting and sorting device 2 and the high-frequency spot welder 3 from being too close, so as to prevent the intermittent vibration caused by the cutting action in the metal foil automatic cutting and sorting device 2 from affecting the working accuracy of the high-frequency spot welder 3.

[0048] Metal foil automatic cutting and sorting device 2, please refer to Figure 4, including a metal foil coil rack 21, a cutter 22, and a sorting machine 23; the metal foil coil rack 21 can place a whole roll of metal foil, and then output the metal foil to the cutter 22; the cutter 22 can cut the metal foil into a specified length to form a metal foil sheet according to the design, or use a mold to cut a specified shape of metal foil from the metal foil; finally, the metal foil is transported to the sorting machine 23 for counting and sorting.

[0049] The specific structure of the finishing machine 23 can refer to the automatic finishing device for copper foil for flexible connection with Chinese patent publication number CN217263726U. The finishing machine 23 counts and sorts the metal foils to form a metal foil stack, which is then taken away by the gripper claw 12 of the robot 1 and then transported to the high-frequency spot welding machine 3 for welding at both ends.

[0050] High frequency spot welding machine 3, please refer to Figure 5 , including a main machine 31, an upper electrode 32, and a lower electrode 33. The lower electrode 33 is fixedly installed on the workbench of the main machine 31. The robot 1 uses the clamping claw 12 to place the metal foil stack to be welded, and one end of the metal foil stack to be welded is placed on the lower electrode 33. Then the upper motor 32 descends to perform pressurized welding to weld the metal foil stack together; after the welding of one end is completed, the clamping claw 12 of the robot 1 moves to place the other end of the metal foil stack to be welded on the lower electrode 33, and continues welding until the welding is completed.

[0051] When all welding is completed, the clamping claw 12 of the robot 1 is released, and the completely welded metal foil stack (which has become a finished or semi-finished metal foil row flexible connector after welding) is clamped by the discharging robot arm 4, removed from the high-frequency spot welding machine 3, and then placed in the cooling device 5.

[0052] like Figure 6 As shown, the discharging robot arm 4 is preferably directly installed on the side of the high-frequency spot welding machine 3 to facilitate the removal of the metal foil row flexible connector from the lower electrode 33.

[0053] Discharging robot arm 4, please refer to Figure 7 , is a multi-degree-of-freedom robotic arm, including a mounting base 41, a main rotating mechanism 42, a lifting mechanism 43, a telescopic mechanism 44, a wrist rotating mechanism 45, a claw driving mechanism 46, and a clamping claw 47. The driving mechanisms are installed together step by step and connected in series to form a multi-degree-of-freedom robotic arm. The end has a clamping claw 47 driven by the claw driving mechanism 46 to achieve parallel clamping, which can clamp the metal foil row soft connector to be transferred.

[0054] Because the placement positions of the high-frequency spot welding machine 3, the discharging robot arm 4, and the cooling device 5 are relatively fixed, in order to improve the driving efficiency, the main rotating mechanism 42 and the wrist rotating mechanism 45 can be pneumatic components to achieve fixed angle rotation; the claw driving mechanism 46 is a cylinder to achieve fixed clamping force; and the lifting mechanism 43 and the telescopic mechanism 44 are screw servo driving devices, which can adjust the driving distance arbitrarily.

[0055] Cooling device 5, for details, please refer to Figure 8 , a conveyor belt 53 and a water-cooling spray head 54 are provided; one end of the conveyor belt 53 is arranged near the high-frequency spot welding machine 3, so that the discharging mechanical arm 4 can quickly transfer the welded metal foil row flexible connector to be cooled from the high-frequency spot welding machine 3 to the cooling device 5; for the convenience of receiving materials, a receiving hopper 52 is provided above the feeding end of the conveyor belt 53, and the receiving hopper 52 is an inclined plate with a large area. The discharging mechanical arm 4 puts the metal foil row flexible connector to be cooled into the receiving hopper 52, and the metal foil row flexible connector to be cooled slowly slides down the receiving hopper 52 onto the conveyor belt 53 to avoid damage to the metal foil row flexible connector caused by collision. A cooling unit is provided along the conveyor belt 53, preferably a water cooling unit, as shown in the figure, that is, a water-cooling spray head 54 is provided on one or both sides of the conveyor belt 53, and the water-cooling spray head 54 is connected to the cooling water tank 6 through a water pump, and spray water is formed on the conveyor belt 53, and the metal foil row flexible connector to be cooled is quickly cooled and cooled by water, and the air is isolated to prevent oxidation. After being transferred by the conveyor belt 53 with the water-cooled spray head 54, the metal foil row flexible connector dissipates the heat stored in the welding process, cools down to a reasonable temperature, and then is conveyed to the receiving hopper 56 to be taken away and inspected. A slope 55 is preferably provided between the receiving hopper 56 and the conveyor belt 53 to prevent the metal foil row flexible connector from falling from the conveyor belt 53 into the receiving hopper 56, and the slope 55 can make the metal foil row flexible connector generate a certain force during the sliding process, so that it slides to the far side of the receiving hopper 56 to avoid material accumulation.

[0056] The main components of the cooling device 5 are installed on the frame 51 , which increases the overall height and is close to the working height of the high-frequency spot welding machine 3 to adapt to the discharge robot arm 4 .

[0057] The cooling device 5 is preferably provided with a cooling water tank 6 separately, for details, see Fig. 9 , the spray water can be filtered, stored, cooled, and connected to the tap water pipe for automatic water replenishment.

[0058] The utility model of the copper and aluminum foil row automatic production system is equipped with a power distribution control cabinet group 7 as a whole. Fig.10 , used for power supply and control.
