[0002] As automobiles become increasingly popular, the demands on their quality as a commodity are rising, and the materials used in automobile production are becoming more diverse. Consequently, sealing and spot welding technologies have become indispensable and important technologies in automobile manufacturing.

[0003] In the existing welding process for precision aluminum alloy automotive parts, manual spot welding is the main method, typically using handheld resistance welding machines. This not only involves high labor intensity and costs but also results in low precision. Furthermore, the consistency and stability of some high-precision weld points cannot be guaranteed, leading to numerous potential quality issues. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic nail-planting and spot welding device for the production of automotive parts, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The worktable is equipped with multiple assembly mechanisms for positioning and installing automotive parts. Each assembly mechanism includes at least a bracket, a rear fixed arm, and a front swing arm. The bracket is fixedly mounted on the worktable. The rear fixed arm is fixedly connected to the bracket, and at least one of the rear fixed arm and / or the front swing arm is equipped with a stud guide. The stud guide has a sleeve for placing the weld stud. The front swing arm is rotated in front of the rear fixed arm via a first drive unit, so that the front swing arm clamps or releases the automotive parts when rotated in front of the rear fixed arm. The robotic arm's movable end is equipped with the spot welding mechanism, which is used to weld weld studs onto the clamped automotive parts.

[0007] Furthermore, the bottom of the workbench is provided with multiple pulley assemblies.

[0008] Furthermore, the bottom of the workbench is provided with multiple lifting units, the telescopic ends of which abut against the bottom of the workbench so that the lifting units drive the workbench to move up and down.

[0009] Furthermore, the first drive unit is fixedly mounted at the bottom of the rear fixed arm, and the output end of the first drive unit is pivotally connected to the lower end of the front swing arm.

[0010] Furthermore, at least two of the rear fixed arms are provided with positioning components, the positioning components including positioning pins that are adapted to positioning holes on automotive parts.

[0011] Furthermore, a linear drive unit is provided on the rear fixed arm and / or the front swing arm, and the pin guide is fixed on the movable end of the linear drive unit so that the linear drive unit drives the pin guide to move linearly.

[0012] Furthermore, the spot welding mechanism includes a welding torch holder connected to a robotic arm and a first welding torch and a second welding torch mounted on the welding torch holder. The electrode heads of the first welding torch and the second welding torch are arranged opposite each other, so that the first welding torch and the second welding torch respectively abut against the automotive parts and the sleeve.

[0013] Furthermore, the first welding torch is fixedly connected to the welding torch holder, and the second welding torch is flipped and mounted on the welding torch holder by a second drive unit.

[0014] Compared with existing technologies, this technical solution provides a fully automated stud spot welding device for automotive parts production, which has the following advantages: the automotive parts are positioned on the rear fixed arm and then clamped between the two by the front swing arm. At the same time as clamping, the welding studs on the stud guide are positioned at the stud positions on the automotive parts. Finally, the spot welding mechanism is operated by a robotic arm to perform welding, which replaces traditional manual spot welding, not only reducing production costs and improving production efficiency, but also ensuring welding accuracy.

[0026] The robotic arm 300 is equipped with a spot welding mechanism 400 at its movable end. The spot welding mechanism 400 is used to weld the weld stud B onto the clamped automotive part A. The automotive part is positioned on the rear fixed arm 220 and then clamped between the two by the front swing arm 230. At the same time as clamping, the weld stud B on the stud guide 240 is positioned at the stud placement position on the automotive part. Finally, the spot welding mechanism 400 is operated by the robotic arm to perform welding, which replaces traditional manual spot welding, not only reducing production costs and improving production efficiency, but also ensuring welding accuracy.

[0027] In this embodiment, the bottom of the workbench 100 is provided with multiple pulley assemblies 500. Each workbench is equipped with an assembly mechanism 200 for different models of automotive parts A.
