Background

Laser welding is commonly used for welding components of golf club heads, such as the body of the club head to a cover plate, striking plate, or weight. In the laser welding process, a laser beam is projected through a focusing lens, so that the laser beam can be focused on a welding position of a workpiece to be welded, and the laser beam can form a Spot (Spot), i.e. a roughly circular light Spot, on the welding position. In general, the diameter of the spot is about 0.3 to 0.5 mm, and therefore the gap between the two components of the workpiece to be welded must be less than 0.3 mm. Therefore, in order to avoid poor welding, the alignment and placement of the two components of the workpiece to be welded must be more accurate, which causes complexity in the steps of the machining process and leads to poor machining efficiency.

Thus, the laser beam emitted from the laser beam emitting hole 14 can form a focus on the projection path, so that a workpiece to be welded can be positioned at the focus for laser welding. A protection lens assembly 15 may be further disposed between the focusing module 13 and the laser beam outlet 14, the protection lens assembly 15 can shield the focusing lens 131, so as to prevent debris or welding sparks of a workpiece from splashing onto the focusing lens 131 to damage the focusing lens 131 when the workpiece is welded.

A lens frame 152 is detachably combined with the through groove 151, so that a protection mirror 153 on the lens frame 152 is located in the accommodating space S and the protection mirror 153 shields the focusing lens 131 and the laser beam outlet 14. Thus, the protective glass 153 can be taken out from the housing 15a, and the protective glass 153 can be easily cleaned or replaced.

Referring to fig. 1, the device body 1 may further includeA gas chamber 16, the gas chamber 16 being located between the laser beam exit 14 and the protective lens assembly 15, the gas chamber 16 having a gas pipe 161, the gas pipe 161 being capable of continuously introducing a protective gas into the gas chamber 16, so that the protective gas forms a gas curtain between the laser beam exit 14 and the protective lens assembly 15, for example, at 5-8 kg/cm ² The protective gas is introduced into the atmosphere. In this manner, the air curtain can further shield the workpiece from debris or welding spark.

For example, the first shaft 22 and the second shaft 25 may be rotated repeatedly by a predetermined angle in a manner of alternately rotating in the forward direction and the reverse direction.
