Claims

1. A laser connector having a focal point adjustable structure, characterized by: The device includes a laser connector body, a focusing cylinder, and a focusing base. The lower end of the laser connector body has a focusing threaded portion with an external focusing thread. The focusing base has a focusing cylinder that can rotate relative to the focusing base. The focusing base has a focusing mounting position to accommodate the focusing threaded portion, allowing the focusing threaded portion to move up and down within the mounting position. The inner wall of the focusing cylinder has an internal focusing thread that mates with the external focusing thread. A guide is provided in the focusing mounting position to restrict the laser connector body from rotating synchronously with the focusing cylinder. The rotation of the focusing cylinder drives the laser connector body to move up and down.

2. The laser connector with a focal point adjustable structure according to claim 1, characterized in that: The focusing threaded part is a focusing threaded component fixedly disposed at the lower end of the laser connector body. The focusing threaded component includes a threaded part and a guide part disposed at the top and bottom, and the focusing external thread is disposed on the threaded part.

3. The laser connector with a focal point adjustable structure according to claim 2, characterized in that: It also includes a first sealing ring, and the guide portion is provided with a first sealing groove that cooperates with the first sealing ring. The first sealing ring is disposed in the first sealing groove. The first sealing ring can cooperate with the inner wall of the focusing mounting position to improve the sealing between the focusing thread and the focusing base.

4. The laser connector with a focal point adjustable structure according to claim 2, characterized in that: The guide component is a guide protrusion fixedly mounted on the focusing base, and the guide part is provided with a guide groove that cooperates with the guide protrusion, and the guide protrusion is disposed in the guide groove.

5. The laser connector with a focal point adjustable structure according to claim 1, characterized in that: The lower end of the focusing tube is provided with an inwardly bent positioning flange. A clamping ring is fixedly provided on the upper surface of the focusing base. A clamping boss is provided around the clamping ring. A positioning groove that cooperates with the positioning flange is provided between the clamping boss and the upper surface of the focusing base. The positioning flange is set in the positioning groove. The positioning groove can prevent the focusing tube from detaching from the focusing base.

6. The laser connector with a focus-adjustable structure according to claim 5, characterized in that: It also includes a damping silicone ring. A silicone groove that mates with the damping silicone ring is provided at the position corresponding to the positioning fold on the upper end surface of the focusing base. The damping silicone ring can mate with the positioning fold to increase the rotational damping of the focusing tube.

7. A laser welded joint, characterized by: The device includes a collimating protective lens module, a collimating lens module, a galvanometer module, a camera module, a focusing lens module, a focusing protective lens module, a laser welding nozzle, and a laser connector with an adjustable focus structure as described in any one of claims 1-6. The laser connector with an adjustable focus structure, the collimating protective lens module, the collimating lens module, the galvanometer module, the focusing lens module, the focusing protective lens module, and the laser welding nozzle are sequentially installed and connected. The camera module is mounted on the galvanometer module, and the position of the camera module coincides with the central axis of the laser welding nozzle.
