Abstract

An assembly system may be provided for attaching together display layers for an electronic device display. The system may include substrate cleaning equipment that includes one or more pressure- sensing cleaning rollers (124) for removing debris from the display layers during assembly operations. A pressure-sensing cleaning roller (124) may include a cylindrical roller member having a tacky surface and one or more pressure sensors (136) configured to sense pressures that are applied to the display layers during cleaning operations. The position and orientation of the cleaning rollers (124) may be adjusted before or during cleaning operations based on pressure data gathered using the pressure sensors. The pressure sensors (136) may be attached to the tacky surface of the cylindrical roller member, attached to an edge of the roller member, embedded within the roller member, or attached to other equipment that moves with the roller member.

Description

technical field [0001] The present invention relates generally to assembly systems, and more particularly to assembly systems for electronic devices with displays. Background technique [0002] Electronic devices such as portable computers and cellular telephones often have displays. Displays are formed from multiple display layers, such as a cover glass layer to protect the display and internal components, a touch screen panel to capture touch input from a user, and a stack of liquid crystal display (LCD) structures to generate displayed images. Adhesives are typically used to laminate the display layers together. [0003] Prior to lamination, the display substrate is passed through a cleaning system to remove debris from the substrate. Such cleaning systems often include a cleaning roller that rolls over the surface of the substrate and collects debris from the substrate. [0004] If care is not taken, excessive pressure from the cleaning roller can damage sensitive dis...
