[0066] (2) Sample handling: After the sample is made, PLC31 transmits a sample making completion signal to the all-in-one HMI. The all-in-one HMI issues a work instruction to PLC31 based on the received signal. PLC31 controls the first servo motor M1 through the first servo driver U1 to make the robotic arm rise to the height above the sample; controls the second servo motor M2 through the second servo driver U2 to move the robotic arm to the same straight line position as the sample; controls the third servo motor M3 through the third servo driver U3 to rotate the robotic arm 90° to the top of the sample and grab the sample; controls the third servo motor M3 through the third servo driver U3 to rotate the robotic arm 0°, controls the first servo motor M1 through the first servo driver U1 to lower the robotic arm to the specified height, and controls the second servo motor M2 through the second servo driver U2 to move the robotic arm to the sample inspection area. The above process completes the sample delivery and pick-up, realizes unmanned operation, saves manpower, and improves the efficiency of inspection.
