DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Refer to Figures 1 - 6As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a turning table 1, a base 2, and a rotating table 3. A rotating motor 4 is arranged at a non-central position inside the turning table 1 and is in transmission connection with the rotating table 3. On both sides of the bottom of the turning table 1, a first turning mechanism 6 and a second turning mechanism 7 with the same structure are symmetrically arranged. The first turning mechanism 6 and the second turning mechanism 7 are in transmission connection with both sides of the base 2. Traditional 3D scanners are mostly used in cooperation with turntables with a single-axis structure, resulting in incomplete scanning when there are certain visual blind spots in the object to be scanned. Therefore, in this embodiment, a two-axis turntable mechanism is set up. Specifically, it is the cooperation between the traditional rotating table structure and the turning table. During scanning, the rotating motor is eccentrically arranged, and the rotating table rotates for circumferential scanning. When the object to be scanned is relatively complex and there are visual blind spots, the two turning mechanisms are controlled to start and drive the turning table to swing. The double-axis rotation of the X-axis and the Y-axis makes the scanning more comprehensive and the scanning effect better.

[0025] More specifically, a support rotating table 8 is clamped and arranged inside the top of the turning table 1. A number of balls 801 are arranged on the support rotating table 8, and the tops of the balls 801 are in rolling connection with the bottom of the rotating table 3. To ensure the smooth rotation of the rotating table, in this embodiment, a support rotating table is arranged at the top of the turning table. The support rotating table is of a ring structure and mainly consists of a ring groove, a cover plate, and balls. A number of balls support the rotating table, and the rotating table rotates on the balls, and the rotation process is stable without jamming.

[0026] More specifically, a rotating gear ring 301 is arranged at the bottom of the rotating table 3. A rotating gear 5 is arranged on the output shaft of the rotating motor 4. The rotating gear 5 meshes with the rotating gear ring 301. A rotating groove 302 is arranged on the outer side of the bottom of the rotating table 3 and is matched with the support rotating table 8. In this embodiment, the rotation of the rotating table is realized through the cooperation of the rotating gear and the rotating gear ring, and a rotating groove is set to cooperate with the support rotating table, specifically to cooperate with the balls, with better guiding effect and smoother rotation.

[0027] More specifically, the first flipping mechanism 6 includes a motor bracket 601 and a flipping motor 602. The flipping motor 602 is installed inside the motor bracket 601, and the output shaft of the flipping motor 602 passes through the motor bracket 601. A driving gear is provided at a position close to the flipping motor housing on the output shaft. A first driven gear 603 is provided on the motor bracket 601. The first driven gear 603 meshes with the driving gear on the output shaft of the flipping motor 602. To enable the flipping motor to drive the rotation of the motor bracket, a driven gear is provided on the motor bracket, so that the output of the flipping motor is transmitted to the first driven gear on one side. Further, a second driven gear 604 is provided below the first driven gear 603. The second driven gear 604 meshes with the first driven gear 603. The outer diameter of the second driven gear 604 is larger than that of the first driven gear 603. A third driven gear 605 is provided outside the second driven gear 604. The outer diameter of the third driven gear 605 is smaller than that of the second driven gear 604, and the third driven gear 605 protrudes from the motor bracket 601. The first driven gear drives the second driven gear to mesh under the drive of the driving gear, and then drives the second driven gear and the third driven gear to rotate. The rotation of the turntable is driven through the cooperation of the third driven gear and the base.

[0028] More specifically, flipping seats 201 are provided on both sides of the base 2. The middle part of the flipping seat 201 is movably connected to the end of the output shaft of the flipping motor 602. A flipping gear ring 202 is provided inside the flipping seat 201. The flipping gear ring 202 meshes with the third driven gear 605. Through the meshing of the third driven gear and the flipping gear ring, with the output shaft as the axis after the flipping motor is started, the flipping seat rotates.

[0029] More specifically, to control the stroke of the turntable, the flipping gear ring 202 is only provided for one-sixth of the circumference at the bottom. When the third driven gear moves to the outermost tooth of the flipping gear ring, it cannot move further, realizing the limit of flipping, so that the turntable can only flip by ±30 degrees. In this embodiment, a flipping angle indication is provided on the outer surface of the flipping seat, so that the working state of the device can be clearly understood and the flipping angle can be better controlled.

[0030] It should be noted that a power indicator light is also provided on the flipping seat on one side of the first flipping mechanism, and a power socket is provided on the flipping seat on one side of the second flipping mechanism. The device can be used after connecting the power supply. In one embodiment, a battery can be provided inside the base for use when there is no power supply.

[0031] More specifically, a PCBA control board 9 is arranged inside the bottom of the base 2. The PCBA control board 9 is electrically connected to the rotary motor 4, the first flipping mechanism 6, and the second flipping mechanism 7. A control switch 11 is arranged inside the flipping base 201 connected to the second flipping mechanism 7. The control switch 11 is electrically connected to the PCBA control board 9. A Bluetooth module is arranged on the PCBA control board 9. In this embodiment, the Bluetooth module is provided, which can be matched and connected with an external electronic device, and the device can be controlled through the external electronic device, making it more convenient to use. The device can also be controlled through the control switch. The control switch includes a power switch and two flipping control switches. Clicking the power switch once turns the device on or off. Double-clicking the power switch after it is turned on resets it to the center position. Long-pressing for 5 seconds connects or disconnects the Bluetooth. Clicking the left-tilting switch tilts it by 5 degrees, and long-pressing makes it tilt continuously. Similarly, clicking the right-tilting switch also tilts it by 5 degrees, and long-pressing makes it tilt continuously. The two control modes can be selected according to the actual situation, making the operation more user-friendly.

[0032] More specifically, a stabilizing shaft 102 is further arranged in the middle of the flipping table 1. A rotary bearing 10 is arranged on the stabilizing shaft 102. A fixing groove 303 is arranged at the center of the bottom of the rotary table 3. The fixing groove 303 is connected to the rotary bearing 10. A scale 101 is arranged on the side of the flipping table 1.

[0033] More specifically, a number of fixing holes are arranged on the rotary table 3. Connecting columns 12 are arranged on the fixing holes. The connecting columns 12 are hollow columns and are provided with internal threads. An anti-slip rubber pad 13 is arranged at the bottom of the base 2.

[0034] The working principle of the present utility model: The item to be scanned is adhered or fixed to the rotary table 3 through screws connected to the connecting columns 12. Press the control switch 11 to start the device. Establish a connection with the turntable through the mobile phone APP. When rotation is needed, control the rotary motor 4 to start. Driven by the cooperation of the rotary gear 5 and the rotary gear ring 301, the rotary table 3 rotates horizontally. The rotation angle can be accurately controlled according to the scale 101 on the rotary table 3. When it is necessary to scan the item at an inclined angle, control the first flipping mechanism 6 and the second flipping mechanism 7 to start. The first driven gear 603 drives the second driven gear 604 to rotate under the drive of the driving gear, and then drives the third driven gear 605 to rotate. Since the third driven gear 605 meshes with the flipping gear ring 202 inside the flipping base 201, the third driven gear 605 moves along the flipping gear ring 202, driving the flipping mechanism and the flipping table 1 to flip. Since the flipping gear ring 202 is only arranged for one-sixth of the circumference, the flipping table 1 flips ±30 degrees on the base 2.

[0035] The above are only used to illustrate the technical solution of the present utility model rather than to limit it. Any other modifications or equivalent substitutions made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
