[0031] Embodiment 1:

[0032] like Figure 1-6As shown, a stereoscopic image acquisition system for automobile cables provided by the present invention comprises: a control box 4, a bracket, a clamping mechanism, a collection mechanism and a moving mechanism; the clamping mechanism comprises a plurality of clamping units; the bracket comprises a top plate 3 and a bottom plate 1; support columns 2 are vertically connected and fixed at the four top corners of the top plate 3 corresponding to the four top corners of the bottom plate 1; each clamping unit is installed on the lower side of the top plate 3 in a horizontal interval manner, and is used to clamp the main terminal of the automobile cable 11; the moving mechanism is installed on the upper side of the bottom plate 1; the collection mechanism is installed on the moving mechanism, and is used to collect images of the automobile cable 11; the collection mechanism is driven by the moving mechanism to rotate and move horizontally on the bottom plate 1; the control box 4 is installed on one of the support columns 2; a controller and a memory electrically connected to the controller are arranged in the control box 4; a display screen 5 and a key panel 6 electrically connected to the controller are installed on the control box 4; the collection mechanism and the moving mechanism are both driven and controlled by the controller.

[0033] The main terminal of the automobile cable 11 is clamped by a clamping mechanism, so that the automobile cable 11 naturally droops and stretches, which is convenient for image collection of the automobile cable 11; the collecting mechanism is driven by a moving mechanism to move horizontally on the bracket, so that the collecting mechanism can take turns to collect images of the automobile cables 11 on each clamping unit; the collecting mechanism is driven by the moving mechanism to rotate, and multi-directional image collection of the automobile cable 11 is performed to reduce manual participation and reduce errors; the display screen 5 is used to display specified information under the control of the controller; the key panel 6 is used to facilitate the control of the collecting mechanism and the moving mechanism through the controller; the image data collected by the collecting mechanism is stored in the memory.

[0034] Furthermore, the clamping unit includes a clamping guide seat 7 and two clamping movable seats 9; the clamping guide seat 7 is transversely fixed on the lower side of the top plate 3; a clamping guide groove is transversely arranged on the lower side of the clamping guide seat 7; a clamping drive screw is rotatably installed transversely in the clamping guide groove, and 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 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; and clamping plates 10 are installed on the lower sides of the two clamping movable seats 9.

[0035] The clamping drive screw is driven to rotate 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 relatively far away, so that the two clamping plates 10 clamp and fix the main terminal of the automobile cable 11, thereby realizing the clamping and positioning of the automobile cable 11.

[0036] Furthermore, the lower sides of the two clamping plates 10 are bent relative to each other to form a bent section; arc-shaped notches are correspondingly provided on the opposite edges of the bent sections of the two clamping plates 10. The two bent sections are used to support the lower side of the main terminal of the automobile cable 11 to improve the stability of the clamping; the two arc-shaped notches are used to avoid the automobile cable 11 to prevent pinching.

[0037] Furthermore, the moving mechanism includes a translation unit and a rotation unit; the translation unit includes a translation track 34, a translation U-shaped seat 12, a translation drive motor 15 and a gear rack pair; the gear rack pair includes a translation drive gear 16 and a translation drive rack 17;

[0038] The translation track 34 is laterally fixed on the upper side of the base plate 1; the translation U-shaped seat 12 is laterally movably installed on the translation track 34; the translation drive rack 17 is laterally installed on the upper side of the translation track 34; the translation drive gear 16 is rotationally installed on the translation U-shaped seat 12 and meshed with the translation drive rack 17; the translation drive motor 15 is used to drive the translation drive gear 16 to rotate, and is electrically connected to the controller through the translation drive circuit.

[0039] The translation drive motor 15 is used to drive the translation drive gear 16 to rotate under the control of the controller. The translation drive gear 16 moves on the translation drive rack 17, driving the translation U-shaped seat 12 to move laterally along the translation track 34 to achieve position movement.

[0040] Furthermore, the longitudinal section of the translation track 34 is T-shaped; the running wheels 13 are rotatably mounted on the inner walls of the front and rear sides of the translation U-shaped seat 12; the running wheels 13 on the same side clamp the edges of the corresponding sides of the translation track 34; the limiting wheels 14 are rotatably mounted on the front and rear side walls of the translation U-shaped seat 12, and the two limiting wheels 14 respectively run on the front and rear side surfaces of the translation track 34. The cooperation between the running wheels 13 and the translation track 34 reduces the friction of the translation U-shaped seat 12 and improves the stability of the movement of the translation U-shaped seat 12; the cooperation between the limiting wheels 14 and the translation track 34 prevents the translation U-shaped seat 12 from shaking back and forth, further improving the stability of the movement of the translation U-shaped seat 12.

[0041] Furthermore, a plurality of label cards 35 are installed at intervals on the translation track 34, and each label card 35 corresponds to the position of each clamping unit; a card reader 18 electrically connected to the controller is installed on the translation U-shaped seat 12, and the card reader 18 is used to read the label card 35. The controller reads the label card 35 through the card reader 18, and after reading the label card 35, the controller controls the translation unit to stop moving, so that the acquisition mechanism can acquire images of the automotive cable 11 on the corresponding clamping unit.

[0042] Furthermore, the rotating unit includes a mounting platform 23, a rotating tube shaft 19, a rotating drive motor 20 and a worm gear pair; the worm gear pair includes a rotating drive worm 21 and a rotating drive worm wheel 22; a center hole is provided at the center of the mounting platform 23; the lower end of the rotating tube shaft 19 is rotatably mounted on the upper side surface of the translational U-shaped seat 12, and the upper end is docked at the lower opening of the center hole; the rotating drive worm 21 is rotatably mounted on the upper side surface of the translational U-shaped seat 12; 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 rotating tube shaft 19, and is meshed with the rotating drive worm 21.

[0043] 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 rotary tube shaft 19 to rotate, so that the installation platform 23 drives the collection mechanism to rotate, so that the collection mechanism performs omnidirectional stereoscopic image collection of the automotive cable 11.

[0044] Furthermore, it also includes multiple cable stretching units; each cable stretching unit includes a bottom buckle 38, a stretching spring 37 and a movable magnet 36; the bottom buckle 38 is U-shaped; the two ends of the bottom buckle 38 are bent horizontally and then bent downward to form a buckle U-shaped section; the two buckle U-shaped sections of the bottom buckle 38 are used to buckle on the terminal of the lowermost branch of the automotive cable 11; the stretching spring 37 is elastically connected to the bottom buckle 38 and the movable magnet 36; a vertical pole coaxial with the rotating tube axis 19 and passing through the center hole is fixed on the upper side surface of the translational U-shaped seat 12; an electromagnet 24 for adsorbing the movable magnet 36 is installed on the upper end of the vertical pole; an electric control switch electrically connected to the controller is connected in series on the power supply line of the electromagnet 24.

[0045] The bottom buckle 38, the tension spring 37, the movable magnet 36 and the electromagnet 24 cooperate to stretch the automobile cable 11, so that the automobile cable 11 is straightened and the vertical pole does not rotate, thereby ensuring the accuracy of image acquisition.

[0046] Furthermore, the collection mechanism includes a lifting drive motor 25, an arc-shaped collection plate 33, two 3D cameras 30 and two lifting drive seats 29; a lifting drive tube 26 and a column 32 are vertically fixed on the upper side of the mounting platform 23; an arc-shaped collection plate 33 with a vertical axis is arranged on the column 32; a lifting drive screw 28 is rotatably installed vertically in the lifting drive tube 26; a long hole 27 is vertically arranged on the lifting drive tube 26; the two lifting drive seats 29 are both vertically slidably installed on the lifting drive tube 26, and a A lifting drive block extends into the lifting drive tube 26; the upper and lower sides of the lifting drive screw 28 are respectively threaded and screwed through the two lifting drive blocks, and the upper and lower sides of the lifting drive screw 28 have the same thread pitch and opposite rotation direction; two 3D cameras 30 are respectively installed on two lifting drive seats 29, and are both electrically connected to the controller; 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; shielding plates 31 are installed on the two lifting drive seats 29; and collection holes corresponding to the positions of the 3D cameras 30 are provided on the shielding plates 31.

[0047] 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 drive seats 29 can be relatively close to or relatively far away, so that the two 3D cameras 30 can collect images at the same time, thereby improving the efficiency of image collection. The arc-shaped collection plate 33 is used to provide a simple background for the automotive cable 11 to prevent the messy environment from affecting the subsequent image analysis.

[0048] Furthermore, the present invention also provides a collection method for a stereoscopic image collection system of automotive cables, comprising the following steps:

[0049] Step 1: Clamp the automotive cable 11 on each clamping unit;

[0050] The clamping drive screw is driven to rotate by hand-twisting the handle 8, and the two clamping movable seats 9 are relatively close to each other, and the two clamping plates 10 clamp and fix the main terminal of the automobile cable 11, and the two bending sections support the lower side of the main terminal of the automobile cable 11;

[0051] Step 2: The moving mechanism moves from the initial position to the final position, and drives the collecting mechanism to stop at each clamping unit in turn;

[0052] The initial position and final position of the moving mechanism are respectively

[0053] The controller controls the translation drive motor 15 to drive the translation drive gear 16 to rotate, and the translation drive gear 16 moves on the translation drive rack 17, driving the translation U-shaped seat 12 to move laterally along the translation track 34; the controller reads the label card 35 through the card reader 18, and controls the translation unit to stop moving after reading the label card 35. After the image acquisition is completed, the controller drives the translation U-shaped seat 12 to continue to move until the next label card 35;

[0054] Step 3: Whenever the moving mechanism moves to a clamping unit, the collecting mechanism collects the automobile cable 11 at the corresponding position, and the moving mechanism drives the collecting mechanism to rotate a certain angle multiple times, and the collecting mechanism collects images again after each rotation;

[0055] The controller controls the lifting drive motor 25 to drive the lifting drive screw 28 to rotate, so that the two lifting drive seats 29 can be relatively close to each other, and the two 3D cameras 30 simultaneously collect images and store the collected images in the memory; the controller controls the rotation drive motor 20 to drive the rotation drive worm 21 to rotate, and the rotation drive worm gear 22 drives the rotation tube shaft 19 to rotate, so that the installation platform 23 drives the collection mechanism to rotate a certain angle, and each time the installation platform 23 rotates, the collection mechanism collects images again;

[0056] Step 4: Remove the car cable 11 after image acquisition, and return the moving mechanism to the initial position;

[0057] The two clamping movable seats 9 are relatively separated by reversely twisting the hand-tightening handle 8, and the vehicle cable 11 is removed;

[0058] Step 5: Repeat steps 1 to 4.
