[0022] Example 1:

[0023] like Figure 1-6 As shown, the present invention provides a three-dimensional image acquisition device for automotive cables, comprising: a control box 4, a mounting bracket, a rotating mechanism, an acquisition mechanism, a clamping mechanism, and a stretching mechanism;

[0024] The mounting bracket includes a base plate 1, a top plate 3 and four columns 2; the lower ends of the four columns 2 are respectively fixed at the four top corners of the base plate 1, and the upper ends are respectively fixed at the four top corners of the top plate 3; the clamping mechanism is installed at the center of the lower side of the top plate 3, and the stretching mechanism is installed on the base plate 1, and the clamping mechanism and the stretching mechanism clamp the automotive cable 11; the rotating mechanism is installed at the center of the upper side of the base plate 1; the acquisition mechanism is installed on the rotating mechanism, and is used to acquire images of the automotive cable 11, and the acquisition mechanism is driven to rotate by the rotating mechanism; the control box 4 is installed on one of the columns 2; a controller and a memory electrically connected to the controller are provided in the control box 4; the rotating mechanism, the acquisition mechanism and the stretching mechanism are all driven by the controller.

[0025] The automobile cable 11 is clamped by using a clamping mechanism and a stretching mechanism to achieve positioning and fixation of the automobile cable 11, and the automobile cable 11 is unfolded, which facilitates the acquisition mechanism to acquire images, ensures the accuracy of the acquired images, and facilitates subsequent data analysis; the acquisition mechanism is used to acquire three-dimensional images of the automobile cable 11, and the rotation mechanism is used to drive the acquisition mechanism to rotate, so that the acquisition mechanism can acquire multi-directional three-dimensional images of the automobile cable 11, thereby improving the accuracy of the acquired image data; the controller stores the acquired image data in the memory.

[0026] Furthermore, a display screen 5 and a key panel 6 electrically connected to the controller are mounted on the control box 4. The display screen 5 is used to display prompt information under the control of the controller; the key panel 6 is used to facilitate the control of the rotating mechanism, the collecting mechanism, and the stretching mechanism through the controller.

[0027] Furthermore, the clamping mechanism includes a clamping guide seat 7 and two clamping movable seats 9; the clamping guide seat 7 is laterally fixed on the lower side surface of the top plate 3; a clamping guide groove is laterally arranged on the lower side surface of the clamping guide seat 7; a clamping drive screw is rotatably installed laterally in the clamping guide groove, and the thread pitch on the left and right sides of the clamping drive screw is the same and the rotation direction is opposite; the two clamping movable seats 9 are slidably installed on the clamping guide seat 7, and the two sides of the clamping drive screw are respectively screwed on the two clamping movable seats 9 with through threads; a hand-tightening handle 8 docked on one end of the clamping drive screw is rotatably installed on the clamping guide seat 7; clamping plates 10 are installed on the lower side surfaces of the two clamping movable seats 9; the lower sides of the two clamping plates 10 are bent relative to each other to form a bending section; arc-shaped notches are correspondingly arranged on the relative edges of the bending sections of the two clamping plates 10.

[0028] The automobile cable 11 is clamped by using a hand-tightening handle 8, a clamping drive screw, two clamping movable seats 9 and two clamping plates 10. The clamping drive screw is twisted by the hand-tightening handle 8. Since the thread pitches on the left and right sides of the clamping drive screw are the same and the rotation directions are opposite, the two clamping movable seats 9 can be relatively close to or away from each other, so that the two clamping plates 10 clamp the main terminal of the automobile cable 11; the bent sections of the two clamping plates 10 can support the lower side of the main terminal of the automobile cable 11, thereby improving the clamping stability; and the two arc-shaped notches are used to avoid the automobile cable 11 to prevent pinching.

[0029] Furthermore, the rotating mechanism includes a rotating drive motor 20, a rotating platform 23 and a worm gear pair; the worm gear pair includes a rotating drive worm wheel 22 and a rotating drive worm 21; a driving tube shaft 19 is rotatably mounted at the center of the upper side surface of the base plate 1; the rotating platform 23 is fixed on the upper end of the driving tube shaft 19; the rotating drive worm 21 is rotatably mounted on the base plate 1; the rotating drive motor 20 is used to drive the rotating drive worm 21 to rotate, and is electrically connected to the controller through a rotating drive circuit; the rotating drive worm wheel 22 is mounted on the driving tube shaft 19 and engages with the rotating drive worm 21.

[0030] The rotary drive motor 20 drives the rotary drive worm 21 to rotate under the control of the controller, and the rotary drive worm wheel 22 drives the drive shaft 19 to rotate, so that the rotary platform 23 drives the acquisition mechanism to rotate, and performs multi-directional image acquisition of the automotive cable 11.

[0031] Furthermore, the stretching mechanism includes an electromagnet 24, a movable magnet 14, a cable buckle 12 and a stretching spring 13;

[0032] The cable buckle 12 is U-shaped; both ends of the cable buckle 12 are bent horizontally and then bent downward to form a buckle U-shaped segment; the two buckle U-shaped segments of the cable buckle 12 are used to buckle on the terminal of the lowermost branch of the automotive cable 11;

[0033] A pull rod is vertically fixed at the center of the base plate 1, which is coaxial with the drive tube axis 19 and passes through the rotating platform 23; the tension spring 13 is elastically connected between the movable magnet 14 and the cable buckle 12; the electromagnet 24 is installed on the upper end of the pull rod for magnetically attracting the movable magnet 14; an electric control switch electrically connected to the controller is connected in series on the power supply line of the electromagnet 24.

[0034] The electromagnet 24 is used to attract the movable magnet 14 so that the tension spring 13 pulls the cable buckle 12, and the cable buckle straightens the automotive cable 11. Due to the installation position of the pull rod, the electromagnet 24 does not rotate with the rotating platform 23, thereby ensuring the accuracy of the image acquisition by the acquisition mechanism.

[0035] Furthermore, the acquisition mechanism includes a lifting drive unit, a curtain panel 16 and two 3D cameras 17; the lifting drive unit is installed on the rotating platform 23; the two 3D cameras 17 are both installed on the lifting drive unit and are electrically connected to the controller, and the lifting drive unit drives the two 3D cameras 17 to move up and down; a support rod 15 is vertically fixed on the rotating platform 23; the curtain panel 16 is fixed on the support rod 15.

[0036] Two 3D cameras 17 are used to simultaneously capture images of the automotive cable 11 to improve the efficiency of image acquisition; a curtain board 16 is used to provide a clean background for the automotive cable 11 to prevent a cluttered environment from affecting subsequent data analysis; and the controller stores the captured images in a memory.

[0037] Furthermore, the lifting drive unit includes a lifting drive column 26, a lifting drive motor 25 and two lifting movable seats 29; the lower end of the lifting drive column 26 is fixed on the rotating platform 23; a long strip hole 27 is vertically provided on the lifting drive column 26; a lifting drive screw 28 is vertically installed in the lifting drive column 26 in a rotatable manner; the thread pitches on the upper and lower sides of the lifting drive screw 28 are the same and the rotation directions are opposite; the two lifting movable seats 29 both vertically slide through the lifting drive column 26, and the driving blocks fixed on the two lifting movable seats 29 are respectively screwed with the threaded penetrations on the upper and lower sides of the lifting drive screw 28; the lifting drive motor 25 is used to drive the lifting drive screw 28 to rotate, and is electrically connected to the controller through the lifting drive circuit; the two 3D cameras 17 are respectively installed on the two lifting movable seats 29; a shielding plate 18 is installed on the two lifting movable seats 29; and the shielding plate 18 is provided with a collection hole corresponding to the position of the corresponding 3D camera 17.

[0038] The lifting drive motor 25 is used to drive the lifting drive screw 28 to rotate under the control of the controller. Since the thread pitches on the upper and lower sides of the lifting drive screw 28 are the same and the rotation directions are opposite, the two lifting movable seats 29 can be relatively close to or relatively far away, so that the two 3D cameras 17 can be raised and lowered for image acquisition; the baffle 18 is used to limit the shooting range of the 3D camera 17.

[0039] In the three-dimensional image acquisition device for automotive cables provided by the present invention, the controller adopts the existing single-chip microcomputer control module; the display screen 5 adopts the existing display screen; the 3D camera 17 adopts the existing camera; the electromagnet 24 adopts the existing electromagnet; the electric control switch adopts the existing electric control switch; the movable magnet adopts magnetic materials such as iron, cobalt, and nickel; the lifting drive motor 25 and the rotation drive motor 20 both adopt existing stepping motors, and the lifting drive circuit and the rotation drive circuit adopt corresponding stepping motor drive circuits.

[0040] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
