Born of Chinese Academy of Sciences technology — SIASUN robots, the full range

The product page of Siasun English official website marks the SA series SCARA as a new generation of S series control cabinets, supporting multiple programming and teaching methods. Different series (desktop SN, six-axis SR, collaborative GCR) do not have identical models for controllers and teach pendants, and spare parts and programs are not interchangeable across series. When selecting or modifying models, refer to the random control cabinet nameplate and the teaching software version. For older models, upgrade and modify requires evaluation of the compatibility between the main encoder and the driver interface, with specific confirmation confirmed by on-site diagnosis.

The official website states that the SR500A has a maximum load capacity of 500kg and can be used in high-dust indoor and outdoor environments. Key maintenance points for heavy load and harsh operating conditions: J1-J3 large gear reducers should replenish or replace grease by operating hours and monitor metal shavings and oil temperature; Regular inspections of main body seals and cable inlet sheaths can cause dust accumulation to affect heat dissipation and insulation; Balance cylinder/balancing mechanism (if any) needs to be inspected. After water ingress or large amounts of powder accumulation, stop the machine for drying and perform insulation testing; abnormalities require on-site diagnosis.

The SA series official standard emphasizes reproduction accuracy of J1+J2/± 0.01-0.02mm. Common causes of accuracy deviation: belt/timing belt tension looseness, wear of Z-axis and J4 couplings, encoder origin drift. Inspection sequence: first perform full-shaft zeroing and zero calibration, then measure the idle return and positioning accuracy of each shaft, and check the mechanical clearance of the transmission components; The main structure generally has no wear parts. If internal clearance in the reducer is the cause, it should be returned to the factory or professionally replaced. If the deviation still exceeds the standard after calibration, on-site inspection must be confirmed.

The GCR series is a 6-axis human-machine collaboration model, with the official website specifying repetition accuracy ±0.02-0.05mm and TCP speed of 2-3.8m/s. After collision trigger protection, first stop the machine and cut off the power, visually inspect the wrist and end flanges for deformation, and check if the load is exceeding limits; Power on again to perform full-axis zeroing and zero reset, and perform TCP calibration to verify accuracy. If collision/torque abnormalities are repeatedly reported, check the joint torque sensor and encoder, and confirm with on-site diagnosis. Do not continue production with deviations.

Like most six-axis/SCARA robots, the absolute encoder relies on the battery to maintain position when powered off. Battery depletion manifests as an alarm for the upclock telegraph position/encoder loss. Battery replacement should be completed within the time limit specified in the control cabinet or manual to avoid losing the origin point after power outages; If the origin has been lost, perform zero reset (aligning the main body scale marks) on each axis according to the manual, and then verify accuracy. Frequent alarms require checking the battery holder contact, the internal cabinet holding circuit, and cables.

The official website states that the SN series comes standard with multi-channel and signal lines, compatible with TCP/IP, Modbus TCP, EIP, Profinet, and other buses, and supports various terminal fixtures. Maintenance points: Regularly check for air leaks and aging of the quick connector; Check for wear and peeling of the signal cables depending on the body's movement parts; After replacing the end effector, check the I/O and fieldbus mapping table. Wrist protection is IP67, and the air source should be kept dry; water and air intake may damage the seal and bearings.

Since Siasun industrialized in 2000, there has been a large stock of early arc welding/spot welding machine models. Old control cabinets often have aging industrial computers/hard drives, black screens of teach pendants, and power supply failures. Most can be repaired at the board level or modified to new S series control cabinets + preserved main unit. Whether it is valuable depends on the remaining precision of the body reducer, motor, encoder, and process requirements; the program can be reconstructed on-site through teaching and reconstruction. It is recommended to first perform overall machine accuracy and body condition testing before making a decision, which should be combined with on-site evaluation.
