Definitions

  • the present invention relates to methods and apparatus for bonding components under pressure. It is concerned particularly, although not exclusively, with bonding a translucent or transparent glass panel to a metal supporting frame to form a door for a large-scale electronic display.
  • large-scale means, in relation to a large-scale electronic display, a minimum visible screen size of approximately 50 inches (127 cm), measured diagonally across the screen.
  • Electronic advertising displays are being used increasingly at the present time. They are now being used in outdoor as well as indoor venues; in locations such as traditional roadside and city centre billboard locations, travel
  • Such displays are typically large—e.g. high-brightness 70 inch (178 cm) or more visible screens that can be viewed by a mass audience from a distance— and very heavy.
  • Such displays typically have a requirement to attach or bond a protective glass panel to metal framework so that an LCD (or other type) screen of the display can be viewed and protected from vandalism and weather.
  • a display is provided with a "glass bonded to metal" opening front door
  • opening and closing the door can put additional stress on the glass— particularly if there are pressure points built up within the glass that are susceptible to movement, twist, heat, cold etc. Fractures in the bond and glass can occur as a result of spot weakness in pressure points under these various conditions. It is known that bonding glass to a metal frame / door can be achieved in a number of ways:-
  • Mechanical fixings such as bolts are provided to apply pressure around the metal frame to fix the glass to the metal;
  • Adhesive a layer of adhesive is provided between the glass and the metal
  • Tape strips of industrial adhesive tape are provided around the metal frame to bond to the glass.
  • Adhesive control of the thickness of the adhesive may be difficult, typically where stand offs (used to control adhesive thickness) provide local pressure points and air pockets or bubbles form within the adhesive bond area;
  • the bond of the glass and the metal frame has to provide sufficient rigidity in the bonded glass door (as a complete unit) for day to day operations of opening, closing and flexing of the bonded glass door structure.
  • Preferred embodiments of the present invention aim to provide methods and apparatus for bonding a glass panel to a metal frame that may be generally improved in the foregoing respects.
  • a method of bonding first and second components comprising the step of compressing the two components together by a device comprising one or more first wheel that applies pressure to an outer surface of the first component and one or more second wheel that applies pressure to an outer surface of the second component, such that the device travels along the first and second components with movement of the first and second wheels, the device further comprising one or more actuator that urges said first wheel(s) and second wheel(s) together in order to compress the two components together and facilitate bonding therebetween, wherein the first and second wheels apply pressure to only a partial region of the outer surfaces of the two components.
  • the term 'wheel' encompasses any wheel, roller or equivalent that rotates to facilitate movement of the device along the two components whilst applying pressure to them.
  • the wheels may apply pressure to the first and second components directly or via one or more element between one or more of the wheels and one or more of the components.
  • the device travels along an edge region of the first and second components in order to compress the two components together along said edge region.
  • an adhesive is applied between the first and second components, prior to compression by said device.
  • said adhesive is an adhesive tape.
  • said adhesive tape is of double-sided closed-cell foam construction with a viscoelastic acrylic core.
  • said device provides an even and consistent pressure across the full width of the adhesive compressed between the two components.
  • said first component is a translucent or transparent panel and said second component is a frame that supports the panel.
  • said panel is of glass.
  • said frame is of metal.
  • a method as above may comprise the steps of applying adhesive to the panel and/ or the frame, bringing the panel and frame together with the adhesive therebetween so that they are bonded together by the adhesive, and applying pressure by said device to compress the panel and frame together with the adhesive therebetween, such that the device travels along an edge region of the panel and frame with movement of the first and second wheels.
  • Such a method may comprise the subsequent step of fitting the panel and frame to the housing of a large-scale electronic display, to serve as a door for said housing.
  • Bonding between the first and second components may be effected by thermal bonding or ultrasonic welding.
  • said device further comprises one or more third wheel that is mounted orthogonally to said first and second wheels and engages a surface to position the device with respect to said first and second components.
  • one or more of said first and second wheels applies pressure to said components via one or more element between one or more of said first and second wheels and one or more of said components.
  • one of said components is supported on a first face of a table that provides a second surface with which the or each said second wheel engages.
  • said table affords a third surface that joins said first and second surfaces and said device comprises one or more third wheel that engages said third surface to position the device with respect to said table.
  • said or each said second wheel and said second surface are provided with one or more interengaging rib and groove.
  • a method as above may be of particular advantage where said first and second components when assembled together form a non-planar assembly.
  • Said device may be moved relative to said two components by a human operator or by a robot.
  • a device for use in bonding first and second components comprises one or more first wheel that, in use, applies pressure to an outer surface of the first component and one or more second wheel that, in use, applies pressure to an outer surface of the second component, such that the device travels along the two components with movement of the first and second wheels, the device further comprising one or more actuator that is arranged to urge said first wheel(s) and second wheel(s) together in order to compress the two components together and facilitate bonding therebetween.
  • said first and second wheels are mounted on a common chassis of the device that is arranged to be moved along an edge region of the first and second components.
  • said chassis is arranged to be moved manually along the edge region of the first and second components.
  • a driving mechanism may be arranged to drive said chassis along an edge region of the first and second components.
  • the or each said actuator is operated pneumatically or hydraulically.
  • the or each said actuator may be operated electrically or mechanically.
  • a device as above may further comprise one or more user key arranged to control operation of one or more said actuator.
  • a device as above may further comprise one or more third wheel that is mounted orthogonally to said first and second wheels and is arranged to engage a surface to position the device with respect to said first and second
