[0026] In this embodiment, during the welding of flexible gallium arsenide (GaAs) batteries, the platform slide rail 3, welding platform 4, gantry slide rail 5, and lifting slide rail 8 are powered by an external power source. The required flexible GaAs batteries are placed on the welding platform 4, which adsorbs and fixes them in place.

[0027] Specifically, a slide rail assembly 11 is provided between the bottom of the welding platform 4 and the top of the machine base 1.

[0028] In this embodiment, when the platform slide rail 3 controls the sliding adjustment of the welding platform 4, the slide rail assembly 11 assists the welding platform 4 in sliding, so that the movement of the welding platform 4 maintains good stability.

[0029] Specifically, a light 12 is fixedly connected to one side of the slide 6, and the light 12 corresponds to the vision component 7.

[0030] In this embodiment, the light 12 provides supplemental lighting to the welding points identified by the vision component 7, enabling the vision component 7 to accurately identify the welding points.

[0031] Specifically, a display 13 is fixedly connected to the top of the machine 1, and the display 13 is electrically connected to an external power supply.

[0032] In this embodiment, the display 13 is used to display the operating status of the entire device welding batteries, which facilitates the judgment of the staff.

[0033] Please see Figure 4 A control method for a resistance welding series device for flexible gallium arsenide battery modules includes the following steps;

[0034] Step S1: The staff places the flexible gallium arsenide batteries on the welding platform 4 according to the required number. The welding platform 4 is activated by an external power source to position and adsorb the placed flexible gallium arsenide batteries.

[0035] Step S2: The platform slide rail 3 and gantry slide rail 5 are started by controlling the external power supply. The gantry slide rail 5 drives the vision component 7 and the welding component 9 on the lifting slide rail 8 to move through the slide block 6. The platform slide rail 3 drives the welding platform 4 to move at the top of the support platform 2, so that the flexible gallium arsenide battery corresponds to the vision component 7. The vision component 7 automatically identifies the welding points on the flexible gallium arsenide battery.

[0036] Step S3: The lifting slide rail 8 is started by controlling the external power supply, the resistance welding power supply 10 controls the welding component 9 to start, the lifting slide rail 8 drives the welding component 9 to move, and the welding component 9 welds the weld points identified by the vision component 7.

[0037] In this embodiment, the operator places the flexible gallium arsenide batteries on the welding platform 4 according to the required number. The welding platform 4 is started by an external power source to position and adsorb the placed flexible gallium arsenide batteries. The platform slide rail 3 and gantry slide rail 5 are started by the external power source. The gantry slide rail 5 drives the vision component 7 and the welding component 9 on the lifting slide rail 8 to move through the slide base 6. The platform slide rail 3 drives the welding platform 4 to move at the top of the support platform 2 so that the flexible gallium arsenide batteries correspond to the vision component 7. The vision component 7 automatically identifies the welding joints on the flexible gallium arsenide batteries. The lifting slide rail 8 is started by the external power source. The resistance welding power source 10 controls the welding component 9 to start. The lifting slide rail 8 drives the welding component 9 to move. The welding component 9 welds the joints identified by the vision component 7.

[0038] Welding platform 4 uses a material positioning device and a battery adsorption device to position and adsorb flexible gallium arsenide batteries.

[0039] Welding platform 4 consists of a material positioning device and a battery adsorption device. Workers place batteries according to the number required for welding. The material positioning device positions the batteries, and the adsorption function of the battery adsorption device ensures that the batteries are firmly adsorbed on welding platform 4.

[0040] The resistance welding power supply 10 is a transistor power supply that uses dual-point welding and has three control modes: voltage control, current control, and power control. The welding output pulse waveform is divided into three segments: rising, holding, and falling.

[0041] The resistance welding power supply 10 can stably supply power to the welding assembly 9, which then welds the battery. The resistance welding power supply 10 also has overload protection for welding parameters such as voltage, current, power, and pressure, timed grinding of the electrode head, and execution of an automatic voltage recovery program, ensuring the welding effect and safety of the welding assembly 9.

[0042] Working Principle: During the welding of flexible gallium arsenide (GaAs) batteries, the required number of flexible GaAs batteries are placed on the welding platform 4. The welding platform 4 positions the flexible GaAs batteries using a material positioning device, and the battery adsorption device ensures that the batteries are firmly adsorbed onto the welding platform 4. The gantry slide rail 5 controls the slide block 6 to move the vision component 7 and the welding component 9 on the lifting slide rail 8. The vision component 7 automatically identifies the solder joints on the flexible GaAs batteries. The lifting slide rail 8 controls the welding component 9 to descend and correspond to the resistance solder joints on the flexible GaAs batteries. The resistance welding power supply 10 is a transistor power supply, which adopts dual-point welding and has three control modes: voltage control, current control, and power control. The welding output pulse waveform is divided into three segments: rising, holding, and falling. It supplies power to the welding component 9 to achieve the welding of the flexible GaAs battery solder joints. After some batteries are welded, the welding platform 4 is moved on the support platform 2 by the platform slide rail 3 to adjust its position, so that the flexible GaAs batteries in different positions can be accurately detected by the vision component 7 to complete the welding of subsequent batteries.
