A fixed block 16 is installed at the output end of the electric telescopic rod 13. The lower end of the I-shaped slider 3 is rotatably connected to a swing rod 17 via a hinge. The end of the swing rod 17 away from the I-shaped slider 3 is rotatably connected to the side wall of the fixed block 16 via a hinge.

[0026] When in use, the electric telescopic rod 13 is activated to extend and retract. The output end of the electric telescopic rod 13 drives the fixed block 16 to move. The fixed block 16 drives the swing rod 17 to swing. The swing rod 17 drives the I-shaped slider 3 to move along the inner wall of the slide groove 10. The I-shaped slider 3 drives the clamping plate 8 to move, so that the clamping plate 8 clamps and fixes the digital isolator chip.

[0027] The position adjustment mechanism includes mounting plates 7 corresponding one-to-one with the I-shaped sliders 3. The mounting plates 7 are installed on the upper side wall of the I-shaped sliders 3 near the clamping plate 8. The mounting plates 7 and the clamping plate 8 are parallel to each other. An internally threaded fixing cylinder 6 is horizontally installed on the mounting plate 7. The internally threaded fixing cylinder 6 is perpendicular to the mounting plate 7. A threaded rod 5 is rotatably connected to the inner wall of the internally threaded fixing cylinder 6 by a thread. One end of the threaded rod 5 near the clamping plate 8 passes through the internally threaded fixing cylinder 6 and is rotatably connected to the side wall of the clamping plate 8. The other end of the threaded rod 5 away from the clamping plate 8 passes through the internally threaded fixing cylinder 6 and is equipped with a rotating block 4 for easy operation by the operator.

[0028] When in use, according to the size of the digital isolator chip, the operator rotates the rotating block 4, which drives the threaded rod 5 to rotate. Under the action of the thread, the threaded rod 5 moves along the inner wall of the internal threaded fixing cylinder 6. The threaded rod 5 drives the clamping plate 8 to move, so that the four clamping plates 8 can clamp and fix the side wall of the digital isolator chip at the same time.

[0029] The angle adjustment mechanism includes a camera 9, which is installed at the center of the upper end of the rotating box 2.

[0030] During use, the camera 9 captures images of the digital isolator chip. The camera 9 then transmits the captured image information to the controller 14 for processing and analysis. The controller 14 then controls the motor 15 to start. The output of the motor 15 drives the rotating box 2 to rotate. The rotating box 2 drives the I-shaped slider 3, the mounting plate 7, and the clamping plate 8 to rotate, aligning the four clamping plates 8 with the four sidewalls of the digital isolator chip.

[0031] Working principle of adjustable digital isolator chip positioning fixture:

[0032] When in use, according to the size of the digital isolator chip, the operator rotates the rotating block 4, which drives the threaded rod 5 to rotate. Under the action of the thread, the threaded rod 5 moves along the inner wall of the internal threaded fixing cylinder 6. The threaded rod 5 drives the clamping plate 8 to move, so that the four clamping plates 8 can clamp and fix the side wall of the digital isolator chip at the same time.

[0033] Then, the camera 9 captures images of the digital isolator chip. The camera 9 transmits the captured image information to the controller 14 for processing and analysis. Then, the controller 14 controls the motor 15 to start. The output of the motor 15 drives the rotating box 2 to rotate. The rotating box 2 drives the I-shaped slider 3, the mounting plate 7, and the clamping plate 8 to rotate, so that the four clamping plates 8 are aligned with the four side walls of the digital isolator chip.

[0034] Then, the fixed frame 1 is moved by a robotic arm or other equipment so that the clamping plate 8 is placed on the digital isolator chip. Then, the electric telescopic rod 13 is activated to extend and retract. The output end of the electric telescopic rod 13 drives the fixed block 16 to move. The fixed block 16 drives the swing rod 17 to swing. The swing rod 17 drives the I-shaped slider 3 to move along the inner wall of the slide groove 10. The I-shaped slider 3 drives the clamping plate 8 to move, so that the clamping plate 8 clamps and fixes the digital isolator chip.
