[0036] like Figures 1-4 As shown, this embodiment provides a camera active alignment device, which includes a workbench, a turntable conveying mechanism 1, a bearing fixture 2 and a lifting mechanism 3. The turntable conveying mechanism 1 includes a rotation drive component 11 and a turntable 12. The rotation drive component 11 is installed on the workbench, and the rotation drive component 11 is driven and connected to the turntable 12. The turntable 12 is provided with at least two mounting positions 121; the bearing fixture 2 is used to carry the product to be assembled, and the bearing fixture 2 can be placed in the mounting position 121; the lifting mechanism 3 is arranged on the workbench, and the rotation drive component 11 is used to drive the turntable 12 to rotate, so that the mounting position 121 where the bearing fixture 2 is placed is rotated to the top of the lifting mechanism 3, and the mounting position 121 is provided with an avoidance hole 122. The output end of the lifting mechanism 3 can penetrate the avoidance hole 122 and drive the bearing fixture 2 to rise to leave the mounting position 121. In this embodiment, two mounting positions 121 are arranged on the turntable 12, and the two mounting positions 121 are symmetrically arranged along the axis of the turntable 12.

[0037] During operation, the support fixture 2 carrying the product to be assembled is placed on the installation position 121, and then the rotating drive assembly 11 drives the turntable 12 to rotate, so that the installation position 121 where the support fixture 2 is placed is rotated to the top of the lifting mechanism 3, and the output end of the lifting mechanism 3 can be penetrated with an avoidance hole 122 and drive the support fixture 2 to rise to the installation position 121, so as to facilitate the active alignment of the subsequent products to be assembled.

In this embodiment, by setting the turntable conveying mechanism 1, the time for reloading the product to be assembled is saved during the product alignment process, the beat of the camera assembly line is improved, and the production efficiency is improved.

[0038] Preferably, if Figure 2 and Figure 3As shown, the mounting position 121 is provided with a plurality of first positioning pins 123, and the plurality of first positioning pins 123 are located on both sides of the avoidance hole 122.

In this embodiment, there are two first positioning pins 123 and two first positioning holes, and the two first positioning pins 123 are symmetrically arranged on both sides of the avoidance hole 122. When the carrying fixture 2 is placed in the mounting position 121, the first positioning pin 123 is inserted into the first positioning hole, thereby improving the assembly accuracy of the carrying fixture 2 and the mounting position 121.

[0039] Preferably, the mounting position 121 is provided with a magnetic component 14, and the magnetic component 14 is magnetically connected to the bottom of the supporting fixture 2. In the present embodiment, the magnetic component 14 is a magnet. There are four magnetic components 14, and the mounting position 121 is provided with four second mounting grooves 125, and the four second mounting grooves 125 are arranged on both sides of the avoidance hole 122.

When the installation position 121 is above the lifting mechanism 3, the shielding plate 163 is located in the detection groove 1621. The through hole 1121 of the hollow rotary table can provide an installation space for the column 161. When the hollow rotary table drives the turntable 12 to rotate, the position of the column 161 remains unchanged. When the shielding plate 163 rotates to the detection groove 1621, the position of the turntable 12 can be obtained through the photoelectric sensor 162, improving the working reliability of the turntable conveying mechanism 1.

When the installation position 121 rotates above the lifting mechanism 3, the shielding plate 163 is located in the detection groove 1621 of one of the photoelectric sensors 162.

[0045] Further, as Figure 4 shown, the lifting mechanism 3 includes a lifting plate 31 and a lifting driving member 32. The lifting driving member 32 is drivingly connected to the lifting plate 31. The lifting plate 31 is provided with a second positioning post 311, and a second positioning hole corresponding to the second positioning post 311 is provided at the bottom of the carrier fixture 2. The second positioning post 311 can be inserted through the second positioning hole. When the lifting driving member 32 drives the lifting plate 31 to lift the carrier fixture 2, the second positioning post 311 is inserted through the second positioning hole. On the one hand, the position accuracy between the carrier fixture 2 and the lifting plate 31 is improved; on the other hand, the stability of the carrier fixture 2 on the lifting plate 31 is improved. In this embodiment, the lifting driving member 32 can be a lifting cylinder.

[0046] Preferably, the lifting mechanism 3 further includes a six-axis optical adjustment frame 33. The lifting driving member 32 is drivingly connected to the six-axis optical adjustment frame 33, and the lifting plate 31 is installed on the six-axis optical adjustment frame 33.

[0047] In this embodiment, as Figures 1-4As shown, the product to be assembled includes a camera and a lens. The camera includes a front housing and an image chip. The camera active alignment device further includes a six-axis mechanism. Before alignment, both the camera and the lens are located on the carrier fixture 2.
