[0037] Referring to Figures 1, 2 and 6, a camera laser AA device for assembling the front lens and circuit board of a camera includes: a laser welding mechanism 10, a focusing mechanism 20, a lifting mechanism 30, a rotating mechanism 40 and an optical environment mechanism 50.

[0038] The rotating mechanism 40 is located at the center of the camera laser AA device. The rotating mechanism 40 is provided with at least two product fixtures 33. As shown in Figure 1 in this embodiment, the rotating mechanism 40 is provided with two product fixtures 33, and preferably the two product fixtures 33 are symmetrically arranged about the central axis of the rotating mechanism 40.

[0039] The laser welding mechanism 10 is located above the rotating mechanism 40. The laser welding mechanism 10 is configured to laser weld and fix the front lens and circuit board after adjustment by the focusing module.

[0040] The focusing mechanism 20 is arranged above the rotating mechanism 40 and at the front end of the laser welding mechanism 10.

The focusing mechanism 20 clamps and fixes the circuit board, so as to ensure the stability of positioning the workpieces on both sides of the weld seam. The clamping and fixing force of the focusing mechanism 20 on the circuit board is greater than the shrinkage force when the solder solidifies, so as to ensure that the relative position of the lens and the image sensor does not change, thereby ensuring the definition of camera focusing.

[0044] In the embodiment, as shown in FIG. 3, the laser welding mechanism 10 includes a laser transplanting module 11 and a laser 12 connected with the movable part of the laser transplanting module 11. The laser 12 is driven by the laser transplanting module 11 to move up and down, so as to adjust the height between the laser 12 and the product, and achieve the best welding effect.

[0045] Specifically, the laser transplanting module 11 can adopt a linear module, or a screw rod module, a cylinder or an oil cylinder assembly, as long as it can drive the laser 12 to move up and down accurately and reciprocally.

It can be understood that the product jig 33 is provided with a corresponding positioning hole.

[0053] The difference between the first positioning member 313 and the second positioning member 323 in the embodiment is the number of positioning pins, i.e., the first positioning pin is provided with two, and the second positioning pin is provided with one, so as to ensure that the product jig 33 has different support points in different directions, thereby providing more stable support and preventing the product jig 33 from being displaced during movement.

[0054] The first lifting assembly 31 and the second lifting assembly 32 adopt horizontal driving sources in a horizontal direction and vertical driving sources in a vertical direction, so as to achieve the actions of positioning and lifting the product jig 33.

Each arc-shaped support 511 of the mounting adjustment assemblies 51 is provided with a light barrel assembly 52, and each light barrel assembly 52 is aligned with the center of the sphere where the arc-shaped support 511 is located.

[0059] Further, the arc-shaped supports 511 are marked with angles, and the angle range is 40°-85°. The mounting blocks 512 can be adjusted to a specific angle to adapt to different use environments or meet specific angle of view requirements.

[0060] The working principle of the utility model is as follows:

[0061] The laser welding mechanism 10 laser welds and fixes the front lens and the circuit board adjusted by the focusing mechanism 20. The focusing mechanism 20 clamps and moves the circuit board, adjusts the relative position and angle of the circuit board and the front lens, and the lifting mechanism 30 clamps the product jig 33 from the left and right sides through the first lifting assembly 31 and the second lifting assembly 32, lifts the product jig 33 to separate from the rotating mechanism 40, and the rotating mechanism 40 rotates and moves the product jig 33, thereby completing the loading and focusing operations.
