康耐视3D位移传感器

康耐视3D位移传感器通过对产品进行三维检测,优化了产品质量。

在电池组装期间,电池封盖会被引导至电池壳的盖子上,然后封盖与壳体相接的地方被焊接起来。极片被焊接到封盖背面的两个端子上,然后卷曲的电池片被放入壳中。虽然这个流程可以手动完成,但3D激光位移传感器和工业相机可使用高速度的几何图案匹配帮助定位焊接区域并检查焊接质量。康耐视 DS1050 3D激光位移传感器可测量正极和负极连接位置的焊缝、极片连接到封盖的位置的焊缝、以及壳体和封盖的角部相接的位置的焊缝。

Pre-Welding Cap Guidance

Cognex’s PatMax software locates the targeted area for 3D inspection. The DS1050 measures the height difference between the top cap and the battery can’s edge to ensure they are close enough. If the parts are level and positioned corrected, the CIC cameras guide the welding machine along a series of selected points for spot- or point-welding. This is a temporary step, before the parts are fully sealed at the next welding station.

100% Inspection

At the second station, the DS925 3D sensor inspects the welded edges or corners where the can and the cap meet to make sure they are fully sealed and free of defects, like bumps or sunken or exploded areas. If the edges pass inspection, the battery can is safe to fill with electrolyte fluid through a small hole before being fully welded shut.
