Detailed Implementation

[0027] To more clearly illustrate the embodiments of this application, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] In the description of the embodiments of this application, the terms "upper," "lower," "front," "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the application. In addition, the terms "first," "second," etc., are only used for distinction in description and have no special meaning.

[0029] According to some embodiments of this application, such as Figures 1 to 6 As shown, a multi-channel laser is provided, including a chassis 1 and a water-cooled plate 11 installed inside the chassis 1. The water-cooled plate 11 is provided with several pump sources 2, beam shapers 4 and apertures 5 arranged sequentially. The chassis 1 is provided with several fiber bundle channels 12, each fiber bundle channel 12 is connected to a fiber bundle 6. The pump sources 2 and the beam shapers 4 are connected through homogenizing fibers 3. The beam shapers 4 and the apertures 5 are arranged opposite each other. The apertures 5 are connected to the fiber bundles 6. Several pump sources 2 emit lasers synchronously. The lasers enter the beam shapers 4 through the corresponding homogenizing fibers 3 and irradiate the corresponding fiber bundles 6 to achieve synchronous transmission of multiple laser beams.

[0030] In some embodiments of this application, a plurality of pump sources 2 are sequentially arranged on the water-cooled plate 11. Each pump source 2 is connected to a homogenizing fiber 3, the homogenizing fiber 3 is connected to a beam shaper 4, and the beam shaper 4 is connected to an aperture 5. The number of pump sources 2 is set to 5, and correspondingly, the number of fiber bundle channels 12 is also set to 5. In practical applications, the number can be set according to actual needs.

[0031] Specifically, the pump source 2 and the beam shaper 4 transmit laser light through the homogenizing fiber 3. The beam shaper 4 converts the Gaussian light in the laser light transmitted through the homogenizing fiber 3 into flat-top light, and removes stray light at the edge through the action of the aperture 5. The transmission through the fiber bundle 6 makes the flat-top light present a uniform effect to meet the welding requirements.

The fiber combining end 61 is inserted into the fiber bundle channel 12. The laser is input from the fiber combining end 61 and output from the fiber splitting end 62. The fiber splitting end 62 can freely and evenly distribute the laser along the contour of the welded part, providing greater flexibility for products with complex contours and facilitating welding.

[0035] In some embodiments of this application, several fiber optic detection sensors 71 are installed inside the chassis 1, and the several fiber optic detection sensors 71 are used to detect the corresponding fiber bundles 6.

[0036] In some embodiments of this application, several PD detection sensors 72 are installed inside the chassis 1. The several PD detection sensors 72 are used to detect the transmission of the corresponding laser, thereby determining whether the laser is output and providing an early warning function.

[0037] In some embodiments of this application, the chassis 1 is provided with a water inlet 15 and a water outlet 14, which are fixed to the water cooling plate 11 to cool the pump source 2 and the beam shaper 4.

[0038] Furthermore, a dry air inlet is provided on the side of the chassis 1 for drying the internal components and preventing condensation inside due to temperature differences.

[0039] In some embodiments of this application, the chassis 1 is provided with several positioning pins 13 to facilitate the installation and removal of the chassis 1.

[0040] In some embodiments of this application, the chassis 1 is provided with a handle 8 to enable manual installation and removal.

[0041] According to some embodiments of this application, a multi-channel laser is provided. By setting multiple channels, the laser can generate multiple laser beams simultaneously, so that the laser can propagate in different channels and finally be output. When welding products with complex contours or irregular structures, synchronous welding and product quality can be guaranteed.
