1. Each moving part, guide rail and roller of the welding robot should be coated with grease, and the closed transmission part should be lubricated with oil to keep the parts moving flexibly; It is the maintenance of the flat center wheel and eccentric wheel parts to ensure their fastening and ensure that the cross arm movement is straight.
2. Frequently inspect and clean the moving parts such as guide rails, carriages, lead screws and nuts to prevent dust accumulation, scattered flux and other sundries, which affect the flexible movement of the moving parts. It is not allowed to collide and wear the joint surface of each sliding guide. Frequently check the wear and tear of key moving parts such as lead screws and racks, and repair or replace them in time to lift nuts if problems are found.
3. The chain in the welding robot is a wearing part, which should be removed and inspected at least once a year and dealt with in a timely manner.
4. Always check the flexibility and reliability of each travel switch, and whether the mechanical protection block is loose or damaged.
5. The fuse of the circuit should be used according to the regulations, and the specifications should not be changed at will.
6. Check the circuit joints frequently to keep the connection firm and reliable plugging.
7. Once every three months, use compressed air to purge the dust in the workstation controller and communicator, so that the relays, knobs, switches, etc. are kept clean and in good contact.
