Both automatic stud welding torches are equipped with four sets of capacitors; while one set is in operation, the other is in reserve to reduce charging time. The system can also communicate with a control system, allowing simultaneous control of voltage adjustments and welding for multiple automatic welding torches as needed.
[0012] An automatic stud welding torch is equipped with two automatic stud feeding systems. The screw feeding process is as follows: vibration inside the screw feeder → ejector pin-type screw delivery device feeds the screw to the air tube feed port → air is supplied into the air tube → ejector pin-type screw delivery device receives and ejects the screw → automatic welding torch receives the screw → X and Y axis drive mechanism moves the automatic welding torch to the workpiece screw welding position for screw welding; during the feeding process, screw selection and feeding are achieved through software programs and conversion sensors.

The robot moves together with the floor rail, which is controlled by the robot's teach-program program and connected to its built-in controller, facilitating the picking and placing of aluminum panels of various sizes. When the robot picks up panels, the incoming panels must be neatly stacked, of a single type, and facing in a single direction. The robot has a panel presence detection function and uses a vacuum suction cup to pick up the panels. The loading and unloading robot is uniformly controlled by a control system.
[0015] The programming route for the automated stud welding process of aluminum single-panel is as follows: Power on (multi-functional host) → Open the program editor → Enter the program name → Import the graphic (or edit the parameters) → Complete the programming (the system will automatically record the information).
[0016] The programming route for the automated stud welding process of aluminum single-panel is as follows: Power on (control console) → Open the work order editor → Enter the work order name → Select the saved program → Enter the dimensions, quantity, and processing time → Sort the work orders (or set up a pre-processing work order) → Complete the work order programming (the system will automatically produce according to the time sequence or the pre-processing work order).
[0017] The described automated stud welding process for aluminum single-panel panels is as follows: Start-up (select work order) → Forklift feeding → Loading and unloading robot loading → Positioning worktable positioning (displacement sensor detects whether there is deviation) → Automatic feeding system feeds studs to automatic welding guns → XY axis drives the dual automatic welding guns to the welding point → Dual automatic welding guns move down synchronously for welding → Repeat the feeding and welding action until welding is completed → Loading and unloading robot unloads → Manual material collection.
[0018] The beneficial effects of this invention are that it develops a fully automatic stud welding equipment for aluminum single-panel panels by changing the traditional stud welding production process and combining automated selection, modification, upgrading, and configuration.

The positioning device 26 uses an automatic arc module positioning system. This module uses a rotating arc clamping module, with a total of 12 clamping modules. Six clamping modules are symmetrically arranged at each end of each workpiece, and fixed limit modules are arranged in the gaps at both ends and in the middle of the clamping modules. Both the fixed limit modules and the arc clamping modules are fixed using U-shaped grooves for easy quick replacement. The positioning worktable 27 is equipped with a displacement sensor to detect whether the aluminum single panel is skewed, ensuring accurate positioning of subsequent nails.

The automatic stud welding gun has good welding stability, high stud feeding reliability, and facilitates the setting of the initial welding position. The welding pressure and stud lifting height are adjustable, and a dedicated pin-pressing stud receiving device is designed and used to improve the reliability and stability of stud feeding.

Screw selection and feeding during the process are achieved through software programs and conversion sensors. Screws of the same diameter with a length difference within 5mm can share one feeding system; screws of different diameters cannot share a system.

4. The fully automatic stud welding equipment for aluminum single-panel according to claim 1, characterized in that, The automatic stud welding torch is a laser welding torch, comprising a metal torch body, precision pneumatic and electromagnetic components. The metal torch body is equipped with precision pneumatic and electromagnetic components. The electromagnetic components include an electromagnetic coil inside the torch body, a solid-state relay and a control transformer externally mounted on the torch body. The control transformer supplies power to the solid-state relay and electromagnetic coil. The solid-state relay acts as a contactless fast-charging switching capacitor. When energized, the electromagnetic coil generates magnetic force that pulls the iron core lever, lifting the stud to establish the arc-starting gap. The automatic stud welding torch exhibits good welding stability, high stud feeding reliability, and convenient initial welding position setting. The welding pressure and stud lifting height are adjustable. A dedicated pin-pressing stud receiving device is designed and used to improve the reliability and stability of stud feeding. The automatic stud welding torch also features automatic detection. Functionally, it can detect screw positioning, welding verticality, welding voltage, downward pressure, and speed. The automatic welding torch's up-and-down, left-and-right movement and telescopic design distance, while meeting processing dimensions, utilizes a custom-designed long-distance cylinder to ensure precise vertical welding of screws on ±1cm uneven surfaces of the sheet metal. Two automatic welding torches can move, position, and weld two screws of the same diameter and length simultaneously according to actual production rhythm requirements. Screws with the same diameter and a length difference within 5mm can share one automatic stud welding torch. Both automatic stud welding torches are equipped with four sets of capacitors; while one set is working, the other set stores energy for backup, reducing charging time. It can also communicate with the control system, allowing simultaneous control of voltage adjustment and welding for multiple automatic welding torches as needed. The automatic stud welding torch is equipped with two automatic stud feeding systems. The screw feeding method is as follows: vibration inside the screw feeder → ejector pin type screw delivery device feeds the screw to the air tube feed port → air is supplied into the air tube → ejector pin type screw device receives the screw and ejects it → automatic welding torch receives the screw → X and Y axis drive mechanism drives the automatic welding torch to the workpiece screw welding position for screw welding; during the feeding process, screw selection and feeding are realized through software program and conversion sensor device; screws of the same diameter with a length difference within 5mm can share one feeding system, while screws of different diameters cannot share one system; the conversion sensor device determines which feeding tube to blow compressed air into and which feeding system material to select.
