What is the content of the pre-service training for the employees of the motor motor automatic screwing machine?
Pre-employment training for motor and motor screwing machine employees is the key to ensuring that employees are able to operate the equipment correctly. Training content mainly includes the following aspects:
First, the theoretical knowledge of equipment
l equipment basic principles
Detailed explanation of the working principle of the motor motor automatic screwing machine. For example, explain how the motor drives the screwing mechanism and how the screw supply system (such as the vibration plate and divider) transports the screws to the specified position in an orderly manner. Through a simple introduction to the mechanical and electrical principles, employees can understand how the various parts of the equipment work in tandem with each other.
For control systems involved, such as PLC (Programmable Logic Controller) control logic, explain them in an easy-to-understand manner. For example, explain how the PLC receives sensor signals and then controls the sequence of motor start/stop and tightening actions.
l Equipment Structure Components
Lead the staff to recognize the various components of the equipment, including the main parts such as the tightening motor, the screw supply device, the transmission parts (e.g. synchronous belt, linear guide, etc.) and the electrical control cabinet. A physical model of the equipment or detailed exploded drawings can be used to enable employees to visualize the location and shape of each component.
Explain the function and role of each component. For example, explain the torque output characteristics of the screwing motor, and the impact of different torque settings on the screwing effect; introduce the linear guide how to ensure that the screwing mechanism of the precise linear movement, to ensure that the screws can be accurately screwed into the workpiece.
Second, the operation skills training
l Equipment operation process
Develop a detailed manual of equipment operation steps, from the pre-startup inspection (such as checking whether the power supply, air source is normal, whether there are obstacles around the equipment, etc.), to the startup of the equipment (including the function of the various control buttons and the order of operation), and then to the normal working state of the screwing operation (such as how to place the workpiece, how to trigger the screwing action, etc.), and then to the shutdown of the equipment steps (including cleaning up the working area, Turn off the power and air source, etc.).
Allow employees to practice the actual operation. During the operation process, the trainer should be on the side to guide and correct the employees' wrong operation in time. For example, some employees may place the workpiece in an inaccurate position, resulting in screwing the screws crooked, the trainer should point out the correct position and method of placement.
l Operation parameter setting
Teach employees how to set the key parameters of the equipment, such as the amount of torque for screwing, rotational speed, screw supply speed and so on. Explain the meaning of each parameter and its impact on the quality of screwing. For example, too much torque may damage the workpiece or screws, and too little torque may lead to poor screwing.
Let employees adjust the parameters through actual operation and observe the effect of screwing under different parameter settings. For example, let employees in the same workpiece, respectively, with different torque values to tighten the screws, and then through the torque tester to check the tightening quality, so that employees intuitively understand the importance of parameter settings.
Third, protection knowledge training
l Mechanical protection
Emphasize the mechanical dangers of the equipment during operation, such as rotating motor shafts, synchronous belts for transmission, etc. may pinch fingers or clothing. Train employees to keep a certain distance when the equipment is running and not to touch the parts that are moving.
Explain the location and use of guards (e.g., guard rails, emergency stop buttons, etc.) on the equipment. For example, inform employees under what circumstances the emergency stop button needs to be pressed and how to resume normal operation of the equipment after pressing it.
l Electrical Protection
Introduce the possible hazards of the equipment's electrical system, such as the risk of electric shock. Train employees to disconnect the power supply and use insulated tools when carrying out electrical inspections or repairs (which must be carried out by authorized personnel). l Electrical Protection
Explain the meaning of the signs inside the electrical control cabinet, such as the voltage levels represented by different colored wires, and how to avoid electrical accidents such as short circuits.
IV. Maintenance Knowledge
l Daily maintenance content
Teach employees to carry out daily maintenance of equipment, including cleaning the dust and oil on the surface of the equipment, checking whether the screws are loose (especially the connecting screws of the key parts of the equipment), and lubricating the moving parts (such as linear guides, bearings of the synchronous belt wheel, etc.).
Develop a checklist for routine maintenance and have employees perform maintenance work according to the contents of the checklist and record the maintenance. For example, the checklist may include items such as “cleanliness of equipment surfaces”, “tightness of key screws”, “lubrication of moving parts”, etc.
l Common Failure Recognition and Simple Handling
Train employees how to identify common faults of the equipment, such as poor screw supply (may be a vibration plate failure or clogging of the distributor), abnormal tightening torque (may be a motor failure or a torque controller failure), and so on.
Teach employees some simple troubleshooting methods, such as cleaning the clogged distributor, checking whether the connecting wires of the motor are loose, and so on. For complex faults that cannot be handled by employees, clearly inform them that they should report them to the maintenance personnel in a timely manner.
