An assembly comprising a substrate 1, a substrate 2 and heat curable adhesive, which is positioned between the substrates 1 and 2, wherein the heat curable adhesive is cured only in a portion of less than 50% of the entire surface covered by the heat curable adhesive. In this manner, the cured parts of the adhesive serve as chemical screws which sufficiently fix the substrates together during further processing steps, but do not involve complete curing of the adhesive.

Methods and apparatus for fabricating adhesive bonded joints while minimizing the voids and/or porosity found in the cured bondline. In accordance with various embodiments, the apparatus comprises an evacuation chamber combined with a pressure inducing device to produce bonded joints that are both void free and thoroughly compacted. The surfaces to be bonded are continuously evacuated throughout the bonding process (pre-mating, mating, debulking and cure). Continuous evacuation is provided via standard vacuum, while the induced pressure can be pneumatically or mechanically provided.

A method for thermally joining thermoplastic fiber composite components, including jointly covering thermoplastic fiber composite components to be joined, at least in the region of a joining zone, with a pressurization arrangement, which is flexible, at least in some section or sections, and extensive pressurization of thermoplastic fiber composite components to be joined by the pressurization arrangement, with the result that the fiber composite components are pressed against one another, at least in the joining zone. The fiber composite components are welded in the joining zone during pressurization. The pressurization is maintained by the pressurization arrangement until the joining zone solidifies. A cover is also disclosed, in particular a mold or diaphragm, for a pressurization device for thermally joining thermoplastic fiber composite components, and an apparatus for thermally joining thermoplastic fiber composite components.

A method for quickly applying and spreading adhesive between substrates without leaving air bubbles. The method includes holding two substrates apart from each other with adhesive sides facing, a second substrate being positioned above a first substrate. The second substrate is suspended in a manner so as to cause a portion to warp towards the first substrate. After a liquid filler is applied between the two substrates, rollers are lowered onto the second substrate and moved so as to disperse the liquid filler between the first and second substrates. In accordance with the rolling of the rollers, end portions of the second substrate are lowered towards the first substrate.

A film-sticking box configured to attach a protective film to an electronic device is provided. The film-sticking box includes a main body and an inner casing. The inner casing accommodates the electronic device. A first opening and a second opening are respectively defined at two opposite ends of the main body. The first opening is configured to pass the protective film therethrough. The inner casing slides in or out via the second opening. When in use, the protective film will take away the dust on the surface of the electronic device to be filmed during pulling, and the user will not pull the drawing film and the inner casing via the same opening to cause dust residue, which can simplify the structure and operation steps to improve user experience.

The device for welding thermoplastic parts includes a matrix for positioning the parts to be assembled, the matrix including an amagnetic insulating insert that defines joining zones in which the welds must be produced, a bladder defining a sealed volume and means for producing a partial vacuum in the sealed volume, and means for moving a magnetic induction head to near the joining zones and without making contact with the bladder. The welding process includes positioning at least one first part, then of placing metal inserts on areas of the first part corresponding to the joining zones that must be welded, and then positioning at least one second part. A bladder is put in place covering the parts and a partial vacuum is created in the volume defined by the bladder. The magnetic induction head is moved to produce the weld bead without contact while the partial vacuum is maintained.

An end effector, for adhesively attaching a first part to a second part, comprises a support, a first nozzle, movable relative to the support, and a second nozzle, movable relative to the support. The first nozzle comprises a first-nozzle-body outlet port and a first-nozzle separator plate. The second nozzle comprises a second-nozzle-body outlet port and a second-nozzle separator plate. The end effector additionally comprises a first ultrasonic-sensor roller that is rotatable relative to the support and located between the first nozzle and the second nozzle. The end effector also comprises a second ultrasonic-sensor roller that is rotatable relative to the support and located between the first ultrasonic-sensor roller and the second nozzle.

A stabilizer bushing installed on a stabilizer bar is made of two divided parts of rubber or the like to prevent or decrease generation of a gap in a bonding surface. The stabilizer bushing installed on an outer periphery of the stabilizer bar by adhesion includes divided rubber bushings of an upper rubber bushing and a lower rubber bushing. Before adhesion, both end portions of the upper and lower rubber bushings, respectively, in a circumferential direction are tapered so that an overlapping amount between the upper and lower rubber bushings increases toward the outer periphery side of the bushings. After adhesion, a bonding surface is bonded by pressure

A water comprising, two component polyurethane dispersion adhesive comprising an anionic polyester polyurethane resin and a solvent-free liquid aliphatic polyisocyanate cross-linker. The dispersion can be reactivated one or more times for edge bonding a flexible sheet material onto a substrate having a main surface, a peripheral surface and an edge connecting the main surface and the peripheral surface.

An apparatus for thermally joining thermoplastic fiber composite components includes a pressurization arrangement for jointly covering, at least in a region of a joining zone, thermoplastic fiber composite components to be joined and applying pressure to the thermoplastic fiber composite components to press the thermoplastic fiber composite components against one another, at least in the joining zone, the pressurization arrangement being flexible, at least in some section or sections. A welding device is configured for welding the fiber composite components in the joining zone during pressurization. The pressurization arrangement and welding device are configured to weld the thermoplastic fiber composite components in a pressurized state in the joining zone. The pressurization arrangement is configured to maintain pressurization independently of the welding device until the joining zone solidifies. A cover is also disclosed for a pressurization device for thermally joining thermoplastic fiber composite components.
