[0037] Specifically, choose a stable and sturdy installation location and place the base in that position.

Install the liftable indexing device on the output end of the servo motor and connect it to the drive via a coupling. Adjust the position of the liftable indexing device so that it is coaxial with the output shaft of the servo motor. Install the first sensor between the servo motor and the liftable indexing device, ensuring that the sensor can accurately detect the angle rotated by the servo motor.

Adjust the position of the photoelectric switch so that its beam is aligned with the axis of the vertical output end of the liftable divider. Ensure the photoelectric switch accurately detects the rotational positioning signal of the gripping mechanism and transmits it to the control system. Next, install the rotating connecting block at the vertical output end of the liftable divider. The rotating connecting block has a recessed cavity to accommodate the flexible transmission mechanism. Ensure the rotating connecting block is securely installed and coaxial with the output shaft of the liftable divider. Install the lifting plate on top of the rotating connecting block. Connect the rotating connecting block and the lifting plate using a circumferentially arrayed rotating lifting adjustment mounting plate. Ensure the rotating lifting adjustment mounting plate is securely installed and provides stable support for the gripping bracket.

Install a lead screw bushing on the lead screw assembly and connect the lifting mounting plate via the lead screw bushing. Ensure the lifting mounting plate can reciprocate vertically under the drive of the lead screw assembly. Install an adjusting handwheel on the top of the lead screw assembly for easy manual adjustment of the gripping assembly's height. Install an openable / closable clamp on the lead screw assembly to fix and adjust the position of the lead screw bushing. Movably mount the gripping bracket on the rectangular positioning slot via a linear guide rail. Ensure the gripping bracket can slide smoothly on the rectangular positioning slot, enabling circumferential position adjustment of the gripping assembly. Install the gripping finger cylinder at the end of the gripping bracket, with its output end pointing vertically downwards. Ensure the gripping finger cylinder is securely installed and operates stably. Symmetrically install fingers at the output end of the gripping finger cylinder, with concave trapezoidal dovetail grooves on the fingers. Ensure the fingers are securely installed and can accurately grip the workpiece. Removably insert pads that fit the concave trapezoidal dovetail grooves onto the fingers.Select a pad of appropriate height, ensuring its height is significantly greater than the depth of the concave trapezoidal dovetail groove to accommodate workpieces of different sizes. Finally, fabricate a columnar liquid pool filled with electrorheological fluid. Electrode transmission shafts, including a first electrode and a second electrode shaft, are positioned opposite each other above and below the liquid pool. Ensure the electrode transmission shafts are securely installed to stably transmit the electric field. The liquid pool is rotatably mounted on the concave cavity of the rotating connecting block via a first bearing. Ensure the liquid pool can rotate smoothly and move synchronously with the gripping mechanism. An insulating layer is installed inside the liquid pool to prevent current leakage.

Fabricate at least two braking components, arranged in a horseshoe shape, comprising, from the inside out, a tightly bonded inner deformation layer, an insulating resin layer, and an outer deformation layer. The inner deformation plate layer is a piezoelectric sensitive material with radial thickness deformation, while the outer deformation plate layer is a piezoelectric sensitive material with circumferential length deformation. Braking components are arrayed along the axis of the second electrode, with adjacent braking components rotating 180° around the axis of the second electrode. The braking components are ensured to be securely installed and able to accurately lock the gripping mechanism when needed. Two power supply circuits are connected to the inner and outer deformation plate layers respectively, ensuring that under the inverse piezoelectric effect, the inner and outer deformation plate layers can deform and compress the second electrode axis, achieving the braking function. Then, the power is turned on, and the control system is started. The control system initializes each sensor to ensure normal operation. The servo motor is started, driving the liftable divider to rotate via a coupling. The liftable divider transmits power to the gripping mechanism, causing it to begin step-by-step rotation. The first sensor detects the angle rotated by the servo motor in real time and transmits the angle signal to the control system. The control system calculates the theoretical position of the gripping mechanism based on the angle signal from the servo motor. The second sensor detects the angle rotated by the liftable divider in real time and transmits the angle signal to the control system. The control system, combined with the angle signal from the liftable divider, further refines the position calculation of the gripping mechanism. The encoder on the servo motor simultaneously detects the rotation angle of the servo motor and transmits the angle signal to the control system. The control system integrates the angle signals from the first sensor, the second sensor, and the encoder to perform omnidirectional detection of the rotated angle. When the gripping mechanism rotates close to the target position, the third sensor (photoelectric switch) begins to detect the rotational positioning signal of the gripping mechanism. The photoelectric switch transmits the detected signal to the control system. When the control system receives the signal from the third sensor, indicating that the gripping mechanism has reached its positioning position, it immediately cuts off the power supply to the flexible transmission mechanism. The strong electric field applied to the electrorheological fluid by the external circuit through the electrode transmission shaft is cut off, the electrorheological fluid in the liquid pool loses its electric field effect, and the power transmission is interrupted.Simultaneously, the inner and outer deformation plates in the braking component deform due to the inverse piezoelectric effect after the electric field is removed, squeezing the second electrode shaft. The braking component is horseshoe-shaped, enabling it to quickly lock the gripping mechanism and stop its rotation. After the gripping mechanism stops rotating, the height of the gripping assembly is adjusted by adjusting the handwheel according to the size and shape of the workpiece. The lead screw assembly is connected to the lifting mounting plate through the lead screw bushing, allowing the gripping assembly to move back and forth vertically to adjust to the appropriate position. The gripping finger cylinder is activated, and the symmetrical fingers at the output end of the gripping finger cylinder open, placing the workpiece between the fingers. Then the gripping finger cylinder retracts, and the fingers clamp the workpiece. The pads on the fingers can adapt to workpieces of different sizes, ensuring gripping stability. When it is necessary to place the workpiece in a designated position, the servo motor is activated, causing the gripping mechanism to rotate to the target position. The process of angle detection and control, power cut-off and braking is repeated to ensure that the gripping mechanism stops accurately at the target position. The gripping finger cylinder is activated, the fingers open, and the workpiece is placed in the designated position. In summary, this invention exhibits superior high-speed rotation performance, enabling extremely fast operation and significantly improving loading and unloading efficiency, fully meeting the urgent needs of modern industry for high-efficiency production. Secondly, it boasts extremely high precision in angle control, achieving omnidirectional angle detection through multiple detection components, accurately controlling the rotation angle of the device and ensuring the accuracy of loading and unloading operations. Thirdly, it possesses excellent flexibility, adapting to workpieces of different sizes and shapes. The adjustable design of the gripping mechanism and detachable pads and other components allow the device to be flexibly adjusted according to actual needs, making it highly versatile. Fourthly, it is safe and reliable in power control. The flexible transmission mechanism can quickly cut off power transmission under specific circumstances, while the braking component can quickly lock the gripping mechanism when power is cut off, effectively avoiding safety accidents caused by unexpected situations and greatly improving the safety and reliability of the device. Finally, the device operates stably and efficiently. Its reasonable structural design and tight cooperation between components provide a solid guarantee for the stable operation of the device. At the same time, advanced technical design and excellent component manufacturing enable the device to maintain a high-efficiency working state during operation, providing a reliable solution for efficient automated production in modern industrial production.
