[0026] like Figures 1 to 6As shown, the utility model provides a dual deviation correction and positioning mechanism, including a first mounting suction head 1, a second mounting suction head 2, an XYR-axis fine-motion platform 3, an R-axis motor 4 and a first Z-axis motor 5, wherein the first Z-axis motor 5 is connected to the XYR-axis fine-motion platform 3, the first mounting suction head 1 is arranged below the XYR-axis fine-motion platform 3, and the second mounting suction head 2 is arranged below the R-axis motor 4. The cooperation between the first mounting suction head 1 and the second mounting suction head 2 can realize the positioning of the forked product, the R-axis motor 4 can realize the deviation correction of the first fork of the forked product, and the XYR-axis fine-motion platform 3 can realize the deviation correction of the second fork of the forked product. The first Z-axis motor 5 can move the entire XYR-axis fine-motion platform 3 and the first mounting suction head 1 in the Z-axis direction.

[0027] The first mounting suction head 1 is connected to the XYR-axis fine-motion platform 3 through the first connecting block 6, a first pressure sensor 7 is arranged between the first connecting block 6 and the first mounting suction head 1, the second mounting suction head 2 is connected to the R-axis motor 4 through the second connecting block 8, a second pressure sensor 9 is arranged between the second connecting block 8 and the second mounting suction head 2, which is used to detect the pressure during assembly to prevent the product from being crushed.

[0028] The XYR-axis fine motion platform 3 includes a mounting plate 30, an X-axis fine motion module 31 disposed on the mounting plate 30 for driving the first mounting suction head 1 to move in the X direction, a Y-axis fine motion module 32 for driving the first mounting suction head 1 to move in the Y direction, a Z-axis fine motion module 33 for driving the first mounting suction head 1 to move in the Z direction, and an R fine motion module 34 for driving the first mounting suction head 1 to swing or rotate. The entire XYR-axis fine motion platform 3 can realize the movement of the first mounting suction head 1 in the X, Y, Z and R directions to achieve a correction effect.

[0029] When in use, the first Z-axis motor 5 can drive the mounting plate 30 to move in the Z-axis direction.

[0030] The X-axis fine-motion module 31 is connected to the Y-axis fine-motion module 32 via a first connecting plate, the Y-axis fine-motion module 32 is connected to the R-axis fine-motion module 34 via a second connecting plate; the Z-axis fine-motion module 33 is connected to the X-axis fine-motion module 31 via a third connecting plate.

[0031] The X-axis fine-motion module 31 includes an X-axis motor, which is connected to an X-axis lead screw arranged in the X direction via a first belt;

[0032] The Y-axis micro-motion module 32 includes a Y-axis motor, which is connected to the Y-axis lead screw via a first coupling;

[0033] The R micro-motion module 34 includes an R motor, which is connected to the worm gear through a second coupling.

[0034] The Z-axis fine-motion module 33 includes a second Z-axis motor, and the second Z-axis motor is connected to the Z-axis lead screw through a third coupling.

[0035] The working principle of the utility model is:

[0036] First, the material-retrieving robot takes the product from the tray and places it on the transfer platform, and then takes a photo with a camera to locate the product position;

[0037] Then, the dual deviation correction positioning mechanism of the utility model moves the second mounting suction head 2 to the corresponding position according to the position guided by the visual system, and the XYR axis micro-motion platform 3 moves the first mounting suction head 1 to the corresponding position;

[0038] Next, the first Z-axis motor 5 moves the XYR-axis micro-motion platform 3 and then the first placement suction head 1 to the transfer platform to pick up the product, and the dual correction mechanism moves to the photo-taking point of the lower camera to take a photo. The dual correction mechanism is adjusted according to the position of the visual system feedback. Specifically, the rotation position of the second placement suction head 2 is adjusted by the R-axis motor 4, and then the position of the first forked part is adjusted. By adjusting the micro-motion platform XYR axis 3, the X-axis and Y-axis positions and rotation positions of the first placement suction head 1 are adjusted, and then the position of the second forked part is adjusted to correct the product to a posture that can be mounted.

[0039] Then, the lower camera takes another photo to confirm whether the product deviation correction reaches the mounting position requirements. The double deviation correction mechanism runs to the mounting point to mount the product and complete the mounting.

[0040] The utility model can solve the problems of low yield rate, large labor force and low efficiency of existing single-correction placement equipment and manual auxiliary fixture equipment. Since the utility model is a double-correction positioning mechanism, the bifurcated product can be double-corrected as a whole for positioning and placement, thereby improving production yield rate and work efficiency, and reducing labor costs and labor intensity.

Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
