Complete the automated conveying and detection task.

[0042] Each device of the system shall have sufficient strength and stiffness, and the mechanical moving mechanism shall operate smoothly, respond quickly and accurately.

[0043] The RGV trolley mainly consists of a traveling mechanism 21, a vehicle body frame, and a workpiece fixing bracket 22.

[0044] The traveling mechanism 21 mainly includes a chassis, wheel components, drive components, etc. The traveling is driven by a set of motor reducers to drive the axle, and the two wheels are driven along the guide rail through the axle, and the other two wheels are driven wheels.

[0045] First, the rigid chain drags the workpiece from the RGV trolley to the erection device, and the dragging ensures a positioning accuracy of 0.5 mm; then, the clamping motor drives the clamping tooling to clamp the workpiece through the lead screw; after fixing, the second-level electric cylinder pushes the workpiece from the horizontal to the vertical state; finally, the lifting motor places the workpiece on the workpiece inspection table through the lead screw, and the clamping claws are released. After the workpiece inspection is completed, the erection device operates in the reverse direction.

[0046] The connection between the erection device and the ground is supported by embedded bolts, and the position of each bolt has an adjustment function to ensure that it is flush with the height of the RGV trolley, meeting the requirement of convenient workpiece handling.

[0047] The flipping accuracy of the erection device is achieved by controlling the accuracy of the electric cylinder. The accuracy of the electric cylinder can ensure ±0.1 mm, and the hinge point of the telescopic rod of the electric cylinder to the rotation center is 500 mm, which is converted into an angular accuracy of

[0048]

[0049] The lifting accuracy of the erection device is controlled by the motor reducer driving the trapezoidal lead screw transmission. When descending to the position, it is sensed by a pressure sensor. When the pressure sensor feedback shows a significant decrease in load, it indicates that the workpiece is installed in place, and the detection accuracy of the pressure sensor is 10 kg.

[0050] The conveying and transferring equipment transports the workpiece to the turntable clamping tooling, and the turntable clamping tooling is clamped and fixed in a pure mechanical structure manner. First, the workpiece is positioned by two positioning pins (cylindrical pin + diamond pin), and the positioning gap is within 0.1 mm to ensure that there is no jamming between each workpiece and the base and the clamping device.

[0051] The clamping tooling 4 consists of a mounting seat, a pressing block, a locking block, a torsion spring, and a pin.

[0052] Before the workpiece is placed, the clamping tooling is in a loose state. Through the downward movement of the workpiece, the pressing block and the locking block rotate counterclockwise. When the workpiece is in place, the pressing block is pressed tightly and the locking block is locked.

[0053] When taking the workpiece, first the gripper presses up the locking block, then the gripper picks up the workpiece, and the pressing block returns to the loose state through the torsion spring.

[0054] It should be noted that the above embodiments can be freely combined as needed. The above introduction is only the preferred embodiments of the present invention and is not intended to limit the present invention.
