自動化檢測技術：提高流程效率的選擇

長期以來，質量保證一直是製造商的首要任務，確保不合格的產品永遠不會離開地板。然而，大批量生產允許在檢查過程中出現一些人為錯誤，從而導致浪費、召回和其他代價高昂的問題。

將自動化檢測技術添加到您的操作中可以防止這些中斷，提高準確性並提高檢測過程的整體效率和一致性。

3種自動檢測技術

目前，三種類型的檢測技術在製造自動化領域佔據主導地位：

屬性檢查：

這種方法採用光學或機械手段來確定特定屬性是否符合給定要求，而無需人工干預。光學屬性檢測包括拍攝零件照片並將其輪廓與可接受或不可接受的圖像進行比較。以每秒一到兩次檢查的速度，自動光學檢查提高了流程效率，平均缺陷率低於百萬分之五十。

尺寸檢驗：

Here, an array of lasers measures the characteristics of each dimension of a part. Similar to optical attribute inspection, this process begins with a comparison based on a predetermined gauge of acceptability. Dimensional inspection can only inspect what sensors can “see,” meaning it cannot measure internal or recessed features. However, due to its 360-degree measurements, a dimensional quality inspection provides very accurate results — though at a slower rate of roughly 30 seconds per part.

三坐標測量機：

These use “touch,” either with mechanics or laser probe, to inspect a part. The slowest method of automation inspection technology, coordinate-measuring machines need several minutes to assess complex parts, but they can measure internal features and compare them to specifications with greater accuracy.

Automation inspection technology can provide levels of accuracy previously only possible via sophisticated analog laboratory instruments. It’ll become much easier to define specifications, handle materials, respond to changes, and adapt the line for greater process efficiency. But as bright as this future may be, the selection process is critical to finding the right solution.

了解自動檢測選項

Before implementing automation inspection technology, it’s critical to ensure the solution is suited for your operations and will provide the intended results. Make sure to ask:

解決方案是否如您需要的那樣徹底？

請記住，並非每一項自動化檢測技術都能看到整個零件。如前所述，尺寸檢查無法衡量內部特徵的可接受性，因此坐標測量機可能更適合您的操作。但是請理解，不規則和不對稱的特徵可能會造成一些困難，可能需要使用不同的軟件進行補償。

它可以測量功能特性嗎？

在測量功能特性（即決定部件是否按預期運行的因素）方面，自動測量確實有局限性。這意味著您可能需要模擬功能環境的機械儀表來驗證自動檢測技術的發現。在此之後，自動檢測設備可以測量過於復雜的特徵和特性。

Again, it’s all about finding the right solution for your operations to guarantee accuracy while bringing about greater process efficiency and cost reductions. Otherwise, you won’t enjoy all the advantages manufacturing automation can offer to quality assurance.
