[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, this utility model provides a skin image acquisition device, including: a mounting base 1, a housing 2 with an opening at the bottom, and a control module 3; the housing 2 is rotatably mounted on one side of the mounting base 1; an acquisition module 4 for acquiring facial skin images is provided on the inner side of the housing 2; the mounting base 1 is provided with a transmission module 5 for driving the housing 2 to rotate at multiple angles and a drive module 6 for driving the transmission module 5; the input end of the transmission module 5 is connected to the output end of the drive module 6; the output end of the transmission module 5 passes through the outer wall of the mounting base 1 and is connected to the housing 2; the control module 3 is electrically connected to the drive module 6 and the acquisition module 4 respectively; Figure 1-4 As shown, the overall structure is stable and easy to install. The drive module 6 drives the outer shell 2 to rotate through the transmission module 5, and then drives the acquisition module 4 installed inside the outer shell 2 to rotate, so as to realize the multi-angle automatic adjustment operation of the acquisition module 4, so as to enable it to perform multi-angle acquisition work. The operation is convenient and fast.

[0024] Further, the transmission module 5 includes: a base plate 51, two arc-shaped rails 52, a rotating arm 53, a transmission seat 54, and a connecting seat 55; the base plate 51 is fixedly installed inside the mounting base 1; the two arc-shaped rails are arranged at intervals from top to bottom in the middle of the mounting plate to form a sliding channel; a plurality of teeth 56 for meshing with the output end of the drive module 6 are provided on the outer side of the lower arc-shaped rail; a plurality of pulleys are provided at the bottom of the transmission seat 54, and the pulleys are slidably connected to the two rails respectively; one end of the rotating arm 53 is fixedly connected to the transmission seat 54, and the other end passes through the side wall of the mounting base 1 and is fixedly connected to the connecting seat 55; the connecting seat 55 is fixedly connected to the outer shell 2.

[0025] In this embodiment, as Figure 1-4 As shown, an arc-shaped guide rail located below engages with tooth 56 to form an arc-shaped transmission rack; the control module 3 controls the drive motor 61 to work. At this time, the drive module 6 drives the transmission seat 54 to slide along the arc-shaped guide rail, thereby driving the rotating arm 53 connected to the transmission seat 54 to rotate. Finally, the rotating arm 53 drives the outer shell 2 to rotate, and the outer shell 2 drives the acquisition module 4 installed inside it to rotate, so as to realize the angle adjustment operation of the acquisition module 4; the operation is convenient and quick; and the gear meshing transmission method can effectively reduce the noise generated during the transmission process.

[0026] Furthermore, it also includes two limiting covers 57; the two limiting covers are fixedly disposed at both ends of the sliding channel. Specifically, the two limiting covers 57 are mainly used to limit the transmission seat 54. By limiting the transmission seat 54, the adjustment angle of the acquisition module 4 is limited, so as to avoid the situation of exceeding the set angle and distance during the adjustment process.

[0027] Furthermore, there are light-shielding elements 58 at both ends of the outer side of the upper arc-shaped guide rail.

[0028] Furthermore, the drive module 6 includes: a drive motor 61 and a transmission gear 62 adapted to the teeth 56; the drive motor 61 is fixedly mounted on the transmission base 54, and its output end is fixedly connected to the transmission gear 62; the transmission gear 62 meshes with the teeth 56, and the drive motor 61 is electrically connected to the control module 3.

[0029] In this embodiment, as Figure 1-4 As shown, the drive motor 61 is a servo motor to ensure transmission accuracy. During operation, the drive motor 61 works under the control of the control module 3, driving the transmission gear 62 at its output end to rotate. During the rotation of the transmission gear 62, it meshes with the teeth 56 on the arc-shaped guide rail. During this process, since the arc-shaped guide rail is fixed, while the drive motor 61 is mounted on the transmission seat 54, the meshing of the transmission gear 62 with the teeth 56 on the arc-shaped guide rail causes the transmission seat 54 to move along the guide rail. In turn, the transmission seat 54 drives the rotating arm 53 to rotate, thereby realizing the angle adjustment operation of the acquisition module 4.

[0030] Furthermore, the controller includes an electrical box and a controller; the controller is connected to the electrical signal acquisition module 4 of the drive motor 61.

[0031] In this embodiment, the controller can be a microcontroller, MCU, PLC, or other controller that controls the orderly operation of individual motor components. In this embodiment, an MCU is selected. During assembly, the controller is installed inside the electrical box. The electrical box can be installed on the mounting base 1 or on the side wall of the outer casing 2.

[0032] Furthermore, the acquisition module 4 includes: at least one visual camera, a mounting bracket 41, and at least one first sensor; the mounting bracket 41 is fixedly installed on the top of the inner side of the housing 2; the visual camera and the first sensor are both installed on the mounting bracket 41 and are respectively electrically connected to the controller.

[0033] In this embodiment, as Figure 1-4As shown, the vision camera uses mature technology products available on the market, which will not be elaborated here; while the first sensor is a laser rangefinder. The laser rangefinder is used in conjunction with machine learning algorithms to autofocus the vision camera. The laser sensor can quickly and accurately measure the distance between the detection head and the skin, and the algorithm can automatically optimize the focal length based on the measurement data.

[0034] Furthermore, it also includes five second sensors; all five second sensors are installed in the mounting base 1 and are equidistantly arranged around the outside of an arc-shaped baffle located above; the five second sensors are electrically connected to the vision camera via the controller.

[0035] In this embodiment, the second actuator is a positioning sensor, which is a mature technology and will not be described in detail here. It is mainly used to position the transmission seat 54. The five second actuators correspond to five orientations. When the transmission seat 54 moves to the position of a second sensor under the drive of the drive module 6, the acquisition module 4 is adjusted to the orientation corresponding to the second actuator. At this time, the controller controls the acquisition module 4 to perform skin image acquisition operation at that angle. The operation is convenient and the accuracy is high.

[0036] Furthermore, the top of the inner side of the outer casing 2 is provided with a plurality of supplementary lights 7; the plurality of supplementary lights 7 are arranged around the outside of the vision camera; the specific supplementary lights 7 are mainly used for supplementary lighting to ensure the acquisition effect.

[0037] Optionally, in this embodiment, the mounting base 1 is composed of two interlocking shells; and a non-circular frame 8 adapted to the human body structure is provided at the opening at the bottom of the shell 2.

[0038] This utility model discloses a skin image acquisition device with a stable overall structure and convenient installation.
