2、Operating skills training
Control panel operation: teach employees to familiarize themselves with the layout of the control panel of the assembly machine, the functions and usage of various buttons (such as start, pause, stop, reset buttons), indicator lights (power indicator, fault indicator, etc.), display (showing the status of the equipment, parameter setting interface, etc.). Employees need to master how to adjust the parameters on the control panel, such as motor speed, assembly pressure, arm movement stroke and other parameter settings, and how to view the real-time operation of the equipment through the display information, fault alarm prompts, and be able to make the correct response.
Manual operation practice: In the state of equipment shutdown and ensure that there is protection, guide employees to manual operation practice, including manual movement of the robot arm to the designated position, adjust the degree of fixture opening and closing and positioning accuracy, loading and unloading of the meson and related parts and so on. Through manual operation, cultivate the staff's feel for the manipulation of the various components of the equipment, familiarize with the logic of the mechanical action of the equipment, laying the foundation for subsequent automated operation.
Automation process operation: systematic training of employees to master the whole process of automation of the equipment, from raw materials feeding (to understand the operation of the feeding device and material placement requirements), meson automatic gripping (robotic arm of the programmed action and gripping strategy), positioning and assembly (according to the precision requirements of the equipment, to master how to ensure that the meson in the process of assembly of the accurate position) to the finished product discharging (unloading of the finished product and the storage of the norms). Let the staff clarify the sequence of each link. Let the staff clear the sequence of each link, articulation points and equipment built-in automatic detection and error correction mechanism to ensure that employees can skillfully guide the equipment to complete the assembly task normally and accurately.
3、Protection training
Mechanical protection: Emphasize the mechanical risks during the operation of the equipment, such as the risk of entanglement of transmission parts (belts, chains, gears, etc.), the risk of fixture injuries, the risk of collision of the robot arm, and so on. Employees are trained to wear personal protective equipment (PPE) correctly, such as protective gloves, overalls, etc., and how to work around the equipment, keep a distance, and strictly follow the standardized procedures for starting and stopping the equipment, so as to prevent mechanical injuries due to mishandling.
Knowledge of electrical protection: Explain the composition of the electrical system involved in the equipment, including the power supply method and voltage level of the electrical components such as DC motors, controllers, sensors and actuators. Teach employees electrical operating procedures, such as forbidding wet-handed operation of electrical equipment, how to recognize electrical fault alarms (e.g., overload and short-circuit alarms) and take emergency measures, and avoiding contact with electrically-charged parts, to prevent electrocution accidents. Regularly organize electrical inspections to ensure the integrity of electrical lines and the reliability of grounding.
Points for fire protection: Popularize the general knowledge of fire protection, such as the location of fire escapes around the equipment, the use of fire extinguishers (including the applicable scenarios of dry powder fire extinguishers and carbon dioxide fire extinguishers), and the process of fire alarms. Let the staff understand the factors that may cause fire in the operation of the equipment (such as electrical short circuit, mechanical friction overheating, flammable materials close to the heat source, etc.), to improve the staff's awareness of fire prevention and emergency response capabilities, to ensure that in case of emergency can take action quickly and effectively.
4、Quality control training
Assembly quality standards: clear meson assembly quality standards, including meson and supporting components with the precision (such as gap requirements, the amount of surplus), the installation position tolerance range, the degree of solidity of the connection (such as threaded connection tightening torque standards) and so on. Through physical samples, drawings labeling or three-dimensional model demonstration, let employees intuitively understand the appearance of qualified products and internal quality characteristics, so that the quality standards in-depth.
Quality inspection methods: train employees to master the commonly used quality inspection tools and methods, such as calipers, micrometers, protractors for measuring dimensional accuracy and angular accuracy, torque wrenches used to detect the torque of the threaded connection, as well as the key points and techniques of visual inspection (such as checking the surface of the meson for scratches, cracks, assembly in place, etc.). Employees need to learn to carry out timely quality self-inspection during and after assembly, and follow the principle of “not accepting substandard products, not manufacturing substandard products, not exporting substandard products” to ensure product quality is in line with standards.
Quality Problem Handling Process: Teach employees how to recognize common quality problems, such as meson assembly skew, loosening, size overrun, etc., and master the corresponding corrective and preventive measures. Once quality problems are found, employees should stop immediately, report according to the prescribed process (fill in the quality problem report form, describing in detail the phenomenon of the problem, the discovery of time, location and other information), processing (such as self-adjustment and repair or notify the professional maintenance personnel), to avoid unqualified products flow into the next process, and at the same time, traceability analysis of the quality problem, to prevent the problem from reoccurring.
5、Maintenance training
Daily maintenance tasks: Introduce the daily maintenance work that employees need to undertake, such as cleaning the surface of the equipment (using the appropriate cleaning agents and cleaning tools to avoid damage to the surface of the equipment), lubrication of mechanical parts (based on the lubrication chart of the equipment, regularly add lubricant or grease to the bearings, guide rails, screws and other moving parts), the inspection of electrical wiring (to see if there is any breakage, looseness, whether the joints are good) and so on. routine maintenance to extend the service life of the equipment and ensure its normal operation.
Regular maintenance project: explain the regular maintenance plan and project of the equipment, including the replacement cycle of transmission parts (such as belts, chains according to the wear and tear of regular replacement, gears according to the degree of wear and mesh precision changes in the appropriate time to change), the calibration cycle of the sensors (the use of standard calibration parts on the photoelectric sensors, encoders, etc., precision calibration), the calibration of the accuracy of the equipment (through the professional measuring instruments for the assembling machine). Sensor calibration cycle (using standard calibration parts to calibrate the accuracy of photoelectric sensors, encoders, etc.), equipment accuracy calibration (using professional measuring instruments to calibrate the assembly machine's table flatness, guide rail straightness, robotic arm positioning accuracy, etc.) Let employees know when they need to cooperate with maintenance personnel to carry out in-depth maintenance to ensure stable equipment performance.
Fault reporting process: Train employees how to identify the initial symptoms of equipment failure, such as abnormal noise (common mechanical failure), increased vibration (may arise from imbalance, loosening, etc.), odor (electrical short-circuit, mechanical overheating may occur), and master the process and specifications of fault reporting. Employees need to know how to accurately describe fault phenomena (including time of occurrence, duration, frequency of occurrence, accompanying symptoms, etc.) to maintenance personnel in a timely manner after discovering a fault, so that maintenance personnel can quickly diagnose and repair the equipment and reduce downtime.
