偵測罐子上的塑膠包膜
應用挑戰
在製造過程中，通常情況下需要在產品可供銷售之前完成多個步驟。透過利用螢光感測器和發光材料的獨特性質，可以簡化其中的許多過程。
解決方案
在所示的應用中，圍繞蓋子和罐頂部的塑膠包膜件有幾個用途：用作罐上的防篡改密封件、防止蓋子在運輸過程中掉下來，並且將毛刷配件固定在罐上。此外，塑膠可以作為防錯工具，保護客戶在準備好使用內容物之前不會溢出內容物。出於這些原因，必須剔除沒有塑膠包膜的罐子，這一點很重要。
因為所使用的塑膠表現出發光性質，所以可以使用QL56系列發光感测器來檢測包裝，而不含塑膠的任何罐都將被剔除。
螢光感測器從大功率LED發出紫外線(UV)光並偵測由發光目標物產生的可見光。該技術允許偵測任何表面上的發光標記（甚至不可見的標記），無論材料、顏色或操作範圍內的距離，只要在用紫外線照射目標物時發出可見光。
QL56感測器使用六個紫外線LED，可發出均勻和強烈的紫外線。結構化的光可以可靠偵測不規則表面上的發光材料，例如在本應用中的蓋子上的塑膠。此外，感測器易於安裝，耐用的鋁外殼確保了強大的性能。
