Description

Technical Field

[0001] The present invention relates to the technical field of business process management, and in particular to a sealing operation process layout optimization method. Background Art

[0002] Sealing technology is one of the most important parts of the assembly process and plays a decisive role in product quality and safety. Corrosion caused by sealing failure will reduce the strength, rigidity and service life of the equipment, and will also cause airtight failure, seriously affecting its use. Sealing technology is a key factor affecting the reliability, safety, maintainability and service life of equipment. Therefore, improving the sealing quality of equipment is an inevitable trend for the high-quality development of aviation companies. However, sealing is a non-mechanized process with a complex production process, high manual participation, weak process stability, and difficulty in qualitative and quantitative evaluation. At present, the sealing management process of relevant companies has not yet formed an efficient operation and a relatively accurate qualitative and quantitative evaluation system. It is still a paper-based management model, and a complete and efficient business process has not been formed. There are problems such as low coordination and poor information transfer. Summary of the invention

[0003] The purpose of the present invention is to provide a sealing operation process layout optimization method, which optimizes and rearranges the sealing operation, and the re-set process is conducive to clarifying responsibilities between departments, standardizing operations, reducing management costs, improving information transmission efficiency, and saving resources;

[0004] To achieve the above object, the present invention provides a sealing operation process layout optimization method, comprising the following steps:

[0005] S1: Carry out sealing operation on the equipment. The operators include technicians, operators, glue dispensers, inspectors and managers. Establish a glue and paint management system, including the first-level menu module and the second-level menu function;

[0006] The first-level menu includes the home page, the process includes the early stage of sealing, the middle stage of sealing, the late stage of sealing, and the background maintenance;

[0007] The home page includes displaying the overall dashboard data and the personal home page. The personal home page corresponds to the operator task interface or the inspector character interface and the glue dispenser task interface;

[0008] S2: For the current pre-sealing period, the ECRS analysis method is used to optimize the pre-sealing period, eliminate unnecessary non-value-added activities, merge information tables, and set the approval process to parallel, so as to set up the secondary menu functions for the pre-sealing period in the primary menu module, including initiating application, producing glue and paint, and receiving glue and paint;

[0009] S3: For the current mid-term sealing, the principle of combining PDCA cycle with actual on-site operations is adopted to optimize and improve the setting of process parameters, and the secondary menu functions are set accordingly for the mid-term sealing in the primary menu module, including planning, execution, inspection and processing;

[0010] S4: For the current post-sealing process, the ESIA analysis method is used to optimize the process, eliminate unnecessary non-value-added activities, simplify necessary non-value-added activities, and set up secondary menu functions for the post-sealing process in the primary menu module, including airing operations and inventory records.

[0011] Preferably, in step S2, the specific process of using ECRS to set the secondary menu corresponding to the sealing pre-stage in the primary menu module is as follows:

[0012] Each application process is recorded in an electronic form to clarify the decision-making needs and the right to know requirements, reduce the number of approvals, and increase the number of copies;

[0013] For the application, the specific information includes equipment model, equipment quantity, process number, glue and paint brand, application weight, user department, operator name, and usage time;

[0014] For the production of glue and paint, it includes the batch number of glue and paint, glue and paint components, preparation completion time, aging time or application period, preparation environment temperature and humidity, and the name of the glue preparer;

[0015] For the glue and paint that are collected, the name of the person who collected the glue and paint, the active period and the aging period are included.

[0016] Preferably, in step S3, the specific process of using PCDA to set the secondary menu corresponding to the sealed intermediate period in the primary menu module is as follows:

[0017] (1) Planning: Develop a strict sealing construction process plan. The technician calculates the amount according to the design drawings and the sealing process aviation standards. The weight of the sealant used = coating area * coating thickness * sealant density, plus the loss percentage to give the theoretical amount;

[0018] (2) Execution: The operator performs the sealing operation according to the requirements of the process documents. After the sealing operation, the equipment is divided into the front, middle, rear and assembly stations according to the overall structure. A weighing device is set up next to each station. After the sealing operation is completed, the remaining weight is directly weighed and accurately recorded. When the theoretical amount and the actual amount deviate greatly, the process department is promptly fed back, and the process department gives the actual reasonable amount value. The inspector approves the actual application weight of the sealant according to the process regulations and is responsible for the consistency of the results;

[0019] (3) Inspection: Feedback sealant usage data to the process engineer, calculate the actual amount of sealant used in a single process, component or whole machine through the data statistics function, and record it;

[0020] (4) Processing: Through multiple data accumulation, the process with correct process parameter settings is standardized.

[0021] Preferably, in step S4, the specific process of using ESIA to set the secondary menu function corresponding to the sealing later stage in the primary menu module is as follows:

[0022] For air-drying operations, it includes the operator's name, start time, estimated end time and warehouse entry personnel;

[0023] For inventory records, including the purchasing department and the warehousing department, the warehousing department sets up early warning measures for sealing raw materials and calculates the production rhythm and usage of sealing raw materials required for production in the current season; the purchasing department establishes a FIFO channel and purchases materials through it. The formula is as follows:

[0024]

[0025] When the FIFO channel is full, no more purchases are planned until a gap appears in the FIFP, and then purchases are made.

[0026] Therefore, the present invention adopts the above-mentioned sealing operation process layout optimization method, which has the following advantages:

[0027] (1) In the present invention, for the early stage of sealing, the application approval method is rearranged. The "approval path" in the equipment sealing operation process is changed from "serial mode" to "parallel". The purpose of approval is to proofread and supervise whether the application and use information of the sealant at the production site is correct and whether it is executed according to the process documents. It is a kind of "information proofreading". Therefore, each inspector can perform the approval work, and change the current form that can only be approved by the inspector responsible for this workstation. By developing an information management platform, the operator fills out the sealant application form and submits it, and all inspectors can proofread and approve it. It avoids the interruption of approval due to the absence of the inspector at this workstation, which not only speeds up the efficiency of the approval process, but also reduces waiting time.

[0028] (2) In the present invention, a weighing process is added for the mid-stage of sealing, so that the amount of glue and paint used in the current sealing operation can be understood in detail, forming a reasonable evaluation system;

[0029] (3) In the present invention, in the later stage of sealing, since the storage time of the sealing raw materials is time-consuming and the sealing paint also has a storage time, the FIFO method is used to rationally plan the purchase of raw materials and reduce unnecessary waste.

[0030] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
