[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example: Reference Figure 1-5 A three-dimensional data acquisition device shown in the figure includes a base 1, two support frames 2 are fixed on the base 1, and an arc-shaped slide rail 3 is fixed on the top of the support frame 2. The two arc-shaped slide rails 3 are symmetrically arranged, and an arc-shaped plate 4 is slidably arranged between the two arc-shaped slide rails 3. A plurality of gear columns 5 are fixed to the outer wall of the arc-shaped plate 4, and a camera 6 is arranged on the inner side of the arc-shaped plate 4. A first motor 7 is provided on the base 1, and a gear 8 is fixed to the output shaft end of the first motor 7. The gear 8 cooperates with the plurality of gear columns 5 on the arc-shaped plate 4 to pull the arc-shaped plate 4 to slide between the two arc-shaped slide rails 3. A clamping assembly and a lifting assembly are provided on the base 1. The lifting assembly is used to lift and rotate the product, and the clamping assembly is used to clamp the product to facilitate separation of the lifting assembly from it;

[0023] The first motor 7 is used to drive the gear 8 to rotate, so that the gear 8 cooperates with the multiple tooth columns 5 on the arc plate 4 to pull the arc plate 4 to rotate along the two arc-shaped slide rails 3. The camera 6 is set on the arc plate 4 and can rotate with the arc plate 4 to collect the top and surrounding image data of the product lifted by the lifting assembly. After the product is clamped by the clamping assembly, the lifting assembly is withdrawn from the bottom of the product, and the camera 6 rotates to the bottom of the product to complete the collection of the bottom information of the product.

[0024] Among them, limit blocks 9 are fixed on the outer sides of both ends of the arc plate 4. The two limit blocks 9 are set to limit the arc plate 4 from disengaging from the two arc slide rails 3, and can effectively limit the rotation range of the arc plate 4. The two limit blocks 9 and multiple gear columns 5 are all located between the two arc slide rails 3 to prevent the gear columns 5 and the limit blocks 9 from affecting the sliding of the arc plate 4 between the two arc slide rails 3.

[0025] The lifting assembly includes two first electric push rods 10, both of which are mounted on the base 1, and the output ends of the two first electric push rods 10 are fixedly mounted with a carrier plate 11, on which a second electric push rod 12 is provided, and the output end of the second electric push rod 12 is fixedly mounted with a support plate 13, on which a second motor 14 is provided, and a tray 15 is fixed to the output shaft end of the second motor 14;

[0026] The product is lifted by the tray 15, and the second motor 14 drives the tray 15 to rotate, which can assist the camera 6 in better collecting data around the product. The second electric push rod 12 can drive the tray 15 to move down after the clamping assembly clamps the product, so that the tray 15 is no longer in contact with the product. The two first electric push rods 10 can pull the tray 15 away from the bottom of the product, so that the lifting assembly will not affect the subsequent camera 6's collection of information about the bottom of the product.

[0027] Among them, the clamping assembly includes a fixing plate 16, which is fixedly mounted on the base 1, and a third electric push rod 17 is provided on the fixing plate 16, and a U-shaped plate 18 is fixedly mounted on the output end of the third electric push rod 17. The left and right sides of the U-shaped plate 18 are respectively provided with a fourth electric push rod 20, and the output end of the fourth electric push rod 20 is fixedly mounted with a clamping plate 19;

[0028] The third electric push rod 17 is used to push the two clamps 19 to the two sides of the product supported by the lifting assembly, and the two fourth electric push rods 20 are controlled to push the two clamps 19 closer to each other so that the two clamps 19 can clamp the product. In this way, the product does not need to be supported by the lifting assembly, which facilitates the subsequent collection of product bottom data.

[0029] Working principle of this utility model:

[0030] The product is placed on the tray 15, which is now located below the camera 6. The camera 6 is activated to collect image data of the top of the product. After the collection is completed, the first motor 7 is operated to drive the gear 8 to rotate. The gear 8 cooperates with the multiple gear columns 5 on the curved plate 4 to pull the curved plate 4 to rotate along the two curved slide rails 3. When the camera 6 rotates 90°, the operation of the first motor 7 is paused, and the second motor 14 is operated to drive the tray 15 to rotate, causing the product supported on the tray 15 to rotate accordingly. The camera 6 is then used to collect image data around the product.

[0031] After the collection is completed, the second motor 14 is controlled to stop running, and the third electric push rod 17 is activated to push the two clamps 19 to the sides of the product. The two fourth electric push rods 20 are controlled to push the two clamps 19 closer to the product until the two clamps 19 clamp the product. The second electric push rod 12 is controlled to move the tray 15 downward so that the tray 15 no longer contacts the product. After that, the two first electric push rods 10 are controlled to push the tray 15 away from under the product. Then, the first motor 7 is continued to be controlled to drive the arc plate 4 to rotate, so that the camera 6 moves to the bottom of the product, and the operation of the first motor 7 is stopped. With the help of the camera 6, the image data of the bottom of the product is collected. In summary, the collection of three-dimensional stereoscopic image data of the product is completed.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
