Through the suspension mechanism 4, the object to be photographed can be suspended and placed, so that the shooting effect of the first CCD camera 5 and the second CCD camera 6 is better, and under the action of the two mounting and clamping mechanisms 3, the first CCD camera 5 and the second CCD camera 6 can be disassembled and assembled, so that cameras of different specifications can be replaced to photograph the object to be photographed. At the same time, under the action of the adjusting mounting mechanism 2, the distance between the two mounting and clamping mechanisms 3 can be adjusted, so that the suspension mechanism 4 can suspend and place objects of different sizes, and ensure that the first CCD camera 5 and the second CCD camera 6 can be in a suitable position to photograph the object to be photographed.

[0055] In more detail, the first CCD camera 5 and the second CCD camera 6 are symmetrically distributed along the suspension mechanism 4 and arranged on the inner sides of the two mounting and clamping mechanisms 3 .

[0056] Further, such as Figure 2 As shown, the adjustment and mounting mechanism 2 in the preferred embodiment of the present invention includes a first mounting plate 21, which is arranged on the inner side of the bearing body 1; an AC motor 22, which is arranged on the lower surface of the bearing body 1; a screw rod 23, which is arranged at the output end of the AC motor 22, and the upper end surface of the screw rod 23 is rotatably arranged on the lower surface of the first mounting plate 21; a second mounting plate 24, which is arranged on the inner side of the bearing body 1; a guide rod 25, which is arranged between the inner side of the bearing body 1 and the lower surface of the second mounting plate 24; a connecting plate 26, which is slidably arranged between the outer sides of the screw rod 23 and the guide rod 25; a mounting sleeve 27, which is arranged on the outer side of the connecting plate 26; two through holes 28, which are symmetrically opened on the outer side of the mounting sleeve 27, and the first mounting plate 21 and the second mounting plate 24 are respectively located on the inner sides of the two through holes 28.

At the same time, the connecting plate 26 is also located on the outer side of the guide rod 25 to slide, so that when the screw rod 23 drives the connecting plate 26 to move, the connecting plate 26 will not rotate with the screw rod 23.

[0060] Further, such as Figure 3 As shown, the mounting clamping mechanism 3 in the preferred embodiment of the present invention includes a support sleeve 31, which is arranged on the front surface of the supporting body 1 or the mounting sleeve 27; two mounting holes 32, which are respectively opened on the upper and lower surfaces of the support sleeve 31; two electric push rods 33, which are symmetrically arranged on the inner side of the support sleeve 31; and two clamping plates 34, which are respectively arranged at the output ends of the two electric push rods 33.

[0061] Furthermore, the clamping plate 34 is an arc-shaped clamping plate; two rubber pads are respectively arranged on one side of the clamping plate 34 away from the electric push rod 33, so as to prevent the clamping plate 34 from causing damage to the first CCD camera 5 or the second CCD camera 6 when clamping the first CCD camera 5 or the second CCD camera 6.

The above operation is reversed, and the first CCD camera 5 or the second CCD camera 6 can be removed from the support sleeve 31, thereby replacing the first CCD camera 5 or the second CCD camera 6.

At the same time, when the object 45 to be photographed is suspended, the position sensor 49 will continuously monitor the position of the object 45. When the position of the object 45 to be photographed changes, the position sensor 49 will transmit a signal to the control panel 47, and the control panel 47 will detect the position of the object 45 through the bidirectional DC current. The source module 44 controls and adjusts the electromagnet 43 to ensure the stability of the object 45 when it is suspended, and turns off the position sensor 49, and then transmits a signal to the bidirectional DC power supply module 44 through the control panel 47, so that the control panel 47 adjusts the current size and current direction of the electromagnet 43, so that the position and angle of the object 45 can be adjusted to ensure that the object 45 can be aligned with the center of the first CCD camera 5 and the second CCD camera 6, so that the first CCD camera 5 and the second CCD camera 6 can simultaneously obtain a clear image of the object 45.

At the same time, the connecting plate 26 is also located on the outer side of the guide rod 25 to slide, so that when the lead screw 23 drives the connecting plate 26 to move, the connecting plate 26 will not rotate with the lead screw 23.

[0069] b. The permanent magnet 46 is arranged outside the object 45 to be photographed, and then the object 45 to be photographed is placed above a number of electromagnets 43 , and then the electromagnets 43 are energized, so that under the action of the electromagnets 43 , the object 45 to be photographed will float above the number of electromagnets 43 .

[0070] c. Place the first CCD camera 5 or the second CCD camera 6 between the two mounting holes 32, and then the electric push rod 33 drives the clamping plate 34 to move, so that the clamping plate 34 clamps the first CCD camera 5 or the second CCD camera 6, thereby completing the installation of the first CCD camera 5 or the second CCD camera 6. The above operation is reversed, and the first CCD camera 5 or the second CCD camera 6 can be removed from the supporting sleeve 31, thereby replacing the first CCD camera 5 or the second CCD camera 6.

[0071] d. Transmit a signal to the bidirectional DC power supply module 44 through the control panel 47, so that the control panel 47 adjusts the current size and current direction of the electromagnet 43, so that the position and angle of the object 45 to be photographed can be adjusted to ensure that the object 45 to be photographed can be aligned with the center of the first CCD camera 5 and the second CCD camera 6, so that the first CCD camera 5 and the second CCD camera 6 can simultaneously obtain a clear image of the object 45 to be photographed, and then the first CCD camera 5 and the second CCD camera 6 are used to capture the image of the object 45.
