【摘要】：該項目來源于某某電子有限公司的某型半自動晶片分選機外觀優(yōu)化設計項目。采用半自動晶片分選機進行晶片分選作業(yè),一般采取坐姿方式進行,在作業(yè)過程中需要上肢長時間進行頻繁的手工操作,是一種典型的手工作業(yè)工種,若晶片分選設備的設計不符合工效學原理,長時間頻繁的的手工操作容易導致一系列肌肉骨骼疾病。因此,在優(yōu)化設計的過程中需要更多地考慮工效學方面的因素,提高產品使用的舒適性。舒適性是人們一貫的追求,在產品優(yōu)化設計過程中,根據(jù)產品特征和操作方式構建恰當?shù)脑u估方法對當前產品進行工效學分析與評價,可以發(fā)現(xiàn)當前產品中存在的工效學問題并給出相應的優(yōu)化設計方向。在優(yōu)化設計方案完成后,對選定的設計方案進行實驗評估驗證,可以確保產品符合工效學原理,從而提高產品使用的舒適性,降低工人患肌肉骨骼疾病的風險。在對合作企業(yè)總經理和工程師進行用戶訪談后,了解了產品主要使用人群、晶片分選作業(yè)的流程以及晶片分選作業(yè)過程中人機交互的關鍵接觸點。然后,對該型需要改進的晶片分選機的工作空間進行了了分析,針對目標使用人群,參照國家標準選取相關的人體尺寸數(shù)據(jù),對晶片分選機的基本尺寸數(shù)據(jù)進行了計算并給出了參考值。此外,對產品目標使用人群進行了用戶訪談,了解他們在操作過程遇到的問題,在此基礎上構建了晶片分選作業(yè)的用戶體驗地圖,將用戶在操作過程中各關鍵接觸點處的問題進行了可視化呈現(xiàn),幫助設計師更好的了解用戶使用過程中遇到的問題。根據(jù)晶片分選作業(yè)作業(yè)的特征,構建了基于用戶作業(yè)姿勢的工效學評價方法,即以RULA快速上肢測評為主,以工作空間和用戶使用產品的主觀舒適度評估為輔的評價方法,并給出了相應的評價指標。利用該方法對當前產品進行了評估,找出了當前產品中存在的問題并給出了相應的優(yōu)化設計方向。最后,進行了晶片分選機的外觀優(yōu)化設計工作,根據(jù)之前實驗評估給出的優(yōu)化設計方向,結合用戶需求分析的結果,設計了多款產品外觀方案,通過德爾菲法對設計方案進行了篩選,并用之前構建的評估方法對選定的設計方案進行了驗證評估,確保優(yōu)化方案符合工效學要求。本研究的成果包括:針對目標使用人群對產品基本尺寸進行了重新計算并給出了推薦值;構建了晶片分選作業(yè)用戶體驗地圖來直觀展示用戶使用產品時遇到的問題;基于晶片分選作業(yè)的特征構建了相應的工效學評估方法;對合作企業(yè)需要進行改進的某型產品進行了工效學評估實驗,找出了其中存在的問題并給出了相應的優(yōu)化設計方向;設計了多款晶片分選機的外觀方案,并從中篩選出最優(yōu)方案,實驗評估結果顯示該方案極大的提升了用戶操作過程中的舒適性。
[Abstract]:The project is derived from the appearance optimization design project of a semi-automatic wafer separator in some electronic co., Ltd. The semi-automatic wafer separator is used for wafer sorting, which is generally carried out by sitting posture. In the process of operation, the upper limbs need frequent manual operation for a long time, so it is a typical manual work type. If the design of the wafer sorting equipment does not conform to the ergonomics principle, Frequent manual manipulation for a long time can easily lead to a series of musculoskeletal diseases. Therefore, more ergonomic factors should be taken into account in the process of optimization design to improve the comfort of the products. In the process of product optimization design, an appropriate evaluation method is constructed according to the product characteristics and operation mode to analyze and evaluate the current product ergonomically. The ergonomics problems existing in the current products can be found and the corresponding optimal design direction can be given. After the completion of the optimal design scheme, the selected design scheme can be evaluated and verified experimentally, which can ensure that the product conforms to the ergonomics principle. In order to improve the comfort of product use and reduce the risk of workers suffering from musculoskeletal diseases. After user interviews with the general manager and engineers of the joint venture, we learned about the main users of the products. The process of wafer sorting and the key contact point of man-machine interaction in the process of wafer sorting. Then, the workspace of the chip sorting machine needed to be improved is analyzed, aiming at the target users. The basic size data of the wafer separator are calculated and the reference values are given according to the relevant human dimension data selected from the national standard. In addition, the user interviews with the target users of the product are carried out. On the basis of understanding the problems they encountered in the operation process, the user experience map of the wafer sorting operation was constructed, and the problems at the key contact points of the user during the operation were visualized. According to the characteristics of wafer sorting operation, an ergonomic evaluation method based on user's job posture is constructed, which is based on RULA fast upper limb evaluation. The evaluation method is supplemented by the subjective comfort evaluation of the products used by the users and the workspace, and the corresponding evaluation indexes are given. The current products are evaluated by this method. The problems existing in the current product are found and the corresponding optimal design direction is given. Finally, the appearance optimization design of the wafer separator is carried out, and the optimal design direction is given according to the previous experimental evaluation. Based on the results of user demand analysis, several product appearance schemes are designed, and the design schemes are screened by Delphi method. The selected design schemes are verified and evaluated by the previous evaluation methods. The results of this study include: the basic size of the product is recalculated for the target users and the recommended value is given; The user experience map of the wafer sorting operation is constructed to show the problems encountered when the user uses the product directly, and the corresponding ergonomics evaluation method is constructed based on the characteristics of the wafer sorting operation. The ergonomics evaluation experiment of a kind of product needed to be improved in the cooperative enterprise is carried out, the existing problems are found out and the corresponding optimum design direction is given, and the appearance scheme of many kinds of wafer separator is designed. The experimental results show that the scheme greatly improves the comfort of the user.
