What are the contents of pre-service training for employees of DC motor motor automatic carbon brush cover assembly machine?
DC motor motor automatic carbon brush cover assembly machine staff pre-training content usually covers the following important aspects:
1、Equipment basics
Equipment structure and principle: detailed explanation of the overall mechanical structure of the assembly machine, including the frame, drive system, fixture system, arm and other components of the structure and connection, so that employees understand the layout of the equipment and the basis of operation. In-depth explanation of the working principle of the DC motor, the role of carbon brushes and cover plates in the motor, and how the assembly machine realizes automated and precise assembly, so that employees can understand the theoretical basis behind each step of operation.
Equipment specifications and parameters: Introduce the key technical specifications of the equipment, such as the range of applicable DC motor models, the dimensional tolerance requirements of the carbon brush cover plate, and the productivity indexes of the assembling machine (e.g., the number of assemblies per hour), etc., so as to ensure that the employees know clearly the working boundaries of the equipment and its performance targets.
2、Operating skill training
Control panel operation: Teach employees to familiarize themselves with the control panel of the assembly machine, including the functions and usage of various buttons, indicator lights, and displays. Employees need to master how to start, pause, stop the equipment, how to adjust the assembly parameters on the control panel (such as pressure, speed, position, etc.), as well as how to view information on the operating status of the equipment and fault alarm prompts.
Manual operation practice: In the equipment shutdown state, guide the staff to carry out manual operation practice, such as manually moving the robot arm, adjusting the fixture position, loading and unloading carbon brushes and covers, etc., to cultivate the staff's feel for the manipulation of the various components of the equipment, laying the foundation for the subsequent automation operation.
Automation operation process: Systematically train the staff to master the automation operation process of the equipment, from raw material loading, automatic grabbing, positioning and assembling of carbon brushes and cover plates to the whole process of finished product discharging. Let the staff make clear the sequence of each link, the key points of convergence and the automatic detection and error correction mechanism of the equipment, to ensure that the staff can skillfully guide the equipment to complete the precise assembly task.
3、Protection knowledge education
Mechanical protection: Emphasize the mechanical protection risks during the operation of the equipment, such as the risk of involvement of transmission components, the risk of clamping fixtures, the risk of collision with the mechanical arm. Train employees on how to properly wear personal protective equipment (PPE), such as protective gloves, coveralls, etc., as well as how to work around the equipment, such as maintaining a suitable distance, following the standardized procedures for starting and stopping the equipment.
Electrical protection: Explain the knowledge of the electrical system involved in the equipment, including the power supply method and voltage level of electrical components such as motors, controllers, sensors, and so on. Teach employees electrical operating procedures, such as forbidding wet hand operation of electrical equipment, how to recognize electrical fault alarms and take emergency measures, avoiding contact with electrically charged parts, etc., so as to prevent electrocution accidents.
Fire protection: Popularize the general knowledge of fire protection, such as the location of fire escapes around the equipment, the use of fire extinguishers, and the fire alarm process. Let the staff understand the factors that may cause fire in the operation of the equipment (such as electrical short circuit, mechanical friction overheating, etc.), and improve the staff's awareness of fire prevention and emergency response capabilities.
4、Quality control points
Assembly quality standards: Define the quality standards of carbon brush cover assembly, including the requirements of carbon brushes and cover fit, the tolerance range of the installation position, and the firmness of the connection. Through physical samples or drawings labeling, let employees intuitively understand the appearance and internal quality characteristics of qualified products.
Quality Inspection Methods: Train employees to master commonly used quality inspection tools and methods, such as calipers, micrometers for measuring dimensional accuracy, torque wrenches for detecting the connection torque, as well as the key points and techniques of visual inspection. Employees need to learn to carry out timely quality self-inspection in the assembly process and after the completion of assembly to ensure that product quality meets the standards.
Quality problem handling: Teach employees how to recognize common quality problems, such as carbon brush installation skewed, loose cover, etc., and master the corresponding corrective and preventive measures. Let employees understand that once found quality problems should immediately stop, according to the prescribed process report, processing, to avoid unqualified products into the next process.
5、Maintenance knowledge
Daily maintenance tasks: Introduce the daily maintenance work that employees need to undertake, such as cleaning the surface of the equipment, lubrication of mechanical parts (such as adding grease to the bearings, drip lubricant to the chain), electrical wiring inspection (to see if there is any breakage, loosening), etc., to extend the service life of the equipment to ensure that the equipment operates normally.
Regular Maintenance Program: Explain the regular maintenance program and projects of the equipment, including the replacement cycle of transmission parts (such as belt and chain replacement), the calibration cycle of the sensor, the calibration of equipment accuracy, and so on. Let employees know when 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, vibration, odor, etc., and master the process and specifications of fault reporting. Employees need to know how to accurately describe the fault phenomenon to the maintenance personnel in time after the discovery of the fault, in order to quickly diagnose and repair the equipment.
