Abstract
A laser welding tool including a welding head, a welding tip mounted to the welding head, a guide pin disposed so as to be spaced apart from the welding tip, a support device that supports the welding head and the guide pin, and a floating apparatus connected to the support device and configured to allow the welding head and the guide pin on the support device move in a floating state, relative to the floating apparatus, along an up-and-down direction and along a right-and-left direction while the guide pin is in a state of contacting a welding target portion during welding.
Claims20
A laser welding tool comprising:
- a welding head;
- a welding tip mounted to the welding head;
- a guide pin disposed so as to be spaced apart from the welding tip;
- a support device that supports the welding head and the guide pin;
- and
- a floating apparatus connected to the support device and configured to allow the welding head and the guide pin on the support device to move in a floating state, relative to the floating apparatus, along an up-and-down direction and along a right-and-left direction while the guide pin is in a state of contacting a welding target portion during welding.
A laser welding system comprising:
- a laser welding tool comprising a welding head, a welding tip mounted to the welding head, a guide pin disposed so as to be spaced apart from the welding tip, a support device that supports the welding head and the guide pin, and a floating apparatus connected to the support device and configured to allow the welding head and the guide pin on the support device to move in a floating state, relative to the floating apparatus, along an up-and-down direction and along a right-and-left direction while the guide pin is in a state of contacting a welding target portion during welding;
- a drive device coupled to and configured to move the laser welding tool;
- and
- a controller configured to control an operation of the drive device and the laser welding tool,
- wherein the drive device is configured to move the laser welding tool during welding so that the guide pin, which is supported in the floating state together with the welding head by the floating apparatus, is guided along and tracks the welding target portion in a state of contacting the welding target portion.
