Lamination Press To Improve Management Capacity And Improve Operations
Jun 27, 2017

Lamination Press The reliability and safety of man-machine systems are increasingly dependent on human reliability. According to the statistics of the General Administration of Safety of China from 2013 to 2014, more than 70% of the accidents were caused by human error, and human error has become the source of the accident. Due to the complexity of human behavior and the change of operating environment, it is difficult for the operator to analyze and forecast the failure probability. At present, it is mainly to improve the management ability and improve the job cognition level to reduce the probability of human failure.

At present, the industry experts have carried out theoretical and practical research on human reliability from various fields. From the above research, it is found that the human reliability method has better performance in the analysis and prediction of cognitive failure probability in the analysis of the operating personnel in a certain situation Effect. Through the correction of CREAM, the failure probability of the cognitive function of the laminator is determined, and the measures to reduce the probability of failure of cognitive function are proposed.

Cognitive reliability and error analysis method (CREAM) is proposed by Dr. Erik, who believes that the probability of human cognitive failure is affected by the situational environment, Erik proposed a unique cognitive model and system, to determine the identity of the operator Know the state and predict its future changes. CREAM attributes the human environment (CPC) to the common performance condition (CPC). Through the mass production experience, CREAM has nine main factors, namely, organizational perfection, working condition, man-machine interface (MMI) and operational support The feasibility of the program / program, the number of targets available,Lamination Press the time available, the time zone, the adequacy of training and experience, and the quality of the cooperation of the team members. Each CPC factor can determine its expected effect on performance reliability based on its horizontal status: improved, not significant, and reduced. At the same time, the definition of the environmental impact index β is: β = Σω decreases - Σω improvement, when β = 0 that its common performance factor is not affected by the situational environment, recorded as CFP0; when β ≠ 0 that its common performance factors affected by the situational environment , Recorded as CFP. CFP, CFP0, β and the relationship coefficient k

Cognitive reliability and model error analysis methods are also known as field control models (COCOM), as shown in Figure 1, which is based on the essence of human reliability analysis methods and is a key issue in addressing human reliability. The method also determines the nine main factors that affect the situational environment, and the control mode area of the person can be accurately determined by the range of [Σ reduction, Σ improvement] and the relationship between the control mode area. At the same time, CREAM gives the failure probability interval corresponding to the control mode, that is, the probability mode of the strategy mode is [0.00005,0.01], the tactical mode is [0.001,0.1], the chance mode is, the chaotic mode is; CERAM also Given the failure mode of cognitive function and its corresponding failure probability base, the basic probability of failure probability is still used here.

Solar Lamination Press is the necessary equipment for each PV module manufacturer. The main function is to press EVA, solar cell, tempered glass, back film (TPT, PET and other materials) under high temperature and vacuum conditions into a certain rigid overall. The main responsibility of the laminator operator is to remove the process card from the component before entering the laminator and record the process card information in the system. After laminating the laminator, the process card is attached to the assembly and the The parameters of the laminator are changed and processed promptly. The good cognitive behavior of the laminator operators is especially important for the PV module manufacturers, and their negligence and missed calls are likely to cause the components in the laminators to be scrapped, the laminators being shut down, and even leave serious safety hazards. Cause the accident to happen. It is known that more than one laminator assembly is scrapped and the injury of the laminator operator is related to the operation procedure of the laminator operator, the abnormal alarm information processing is not timely and so on. Therefore, the behavior of the laminator operator is predicted and determined Its cognitive state has great significance.

The operation of the laminator operator has the following characteristics: The laminator personnel must repeatedly check the component process card information and enter the system, while the laminator equipment in the instrument data to observe, according to the laminator in the instrument Data changes determine the normal operation of the laminator or not, and then take the adjustment parameters, stop into the box maintenance or reporting waiting for maintenance and other measures, and then repeat the process; laminator operators operating behavior will be their operating environment and Job status, the performance of the operator is not a random incident, is completed by the entire job content and operating environment of the decision.
