Disclosed herein are various systems, sub-system, and methods for the manufacture of a wall module for using in building a modular construction unit, e.g., for using in building residential homes, commercial offices, educational or service facilities, etc. using a substantially entirely automated modular construction technique. According to the disclosure herein, the resulting wall module includes an internal wall frame including wall studs attached between a top plate and a bottom plate, with, in some embodiment, one or more framing sub-assemblies attached therein to define openings through the wall module. The wall frame has suitable panel members the respective surfaces thereof corresponding to the interior and exterior surfaces of the modular construction unit. The wall frames, when completely assembled, can be transported to be assembled with other constituent components of the modular construction unit to complete the manufacture of the modular construction unit.

A fastening system includes a carriage moveably mounted to a frame between first and second positions extensive with and beyond a fixture. The fixture is horizontally movably mounted in the frame to receive components to be fastened of differing sizes, with slide bars vertically moveably mounted relative to the fixture and simultaneously horizontally movable with the fixture. Adjustable spacers, in the form of a body having different extents or telescopic pillars, are positioned in the frame to abut with the components received in the fixture. Wheels rotatably mounted to first and second platforms of the carriage are received in U-shaped channels of the frame, with the first and second platforms being moved by endless belts clamped thereto. Nail guns are movably mounted between vertical posts of the platforms and include a plunger which is biased against a drum carrying a belt of fasteners and include a flat board tangential to a roller having a V-shaped circumferential groove receiving the heads of nails. The slide bars are movable relative to the fixture by pivoting first and second links which are pivotably connected to each other.

A nail plater apparatus includes a board magazine configured to hold stacked boards, and a pair of spaced apart nail plate magazines, with each nail plate magazine configured to hold stacked nail plates. The nail plater apparatus includes a pair of spaced apart nail plate extractor assemblies, with each nail plate extractor assembly associated with a respective nail plate magazine and configured to position a nail plate therefrom to a respective nail plate pressing area. A board feeder is configured to position a board from the board magazine to a board receiving area, with ends of the board being aligned with the nail plates positioned in the respective nail plate pressing areas. A pair of spaced apart nail plate presser assemblies overlie ends of the board receiving area and is aligned with the respective nail plate pressing areas to press the nail plates into the ends of the board.

Systems and methods for a stud plate connector are disclosed. The system can include a base plate having a first cam slot and a second cam slot, where the second cam slot is approximately a mirror image of the first cam slot. The system can include a first upper cam-follower located within the first cam slot. The system can include a second upper cam-follower located within the second cam slot, where the first and second cam-followers hold opposite sides of a first lumber and move the first lumber to contact a second lumber. The system can include a first lower gripper and a second lower gripper for holding the second lumber in a perpendicular direction with respect to the first lumber. The system can include a bonding device located before to the first and second lumber, where the bonding device bonds the first and second lumber together

A system and method for assembling framing assemblies for use as ceiling or floor structures of modular building units using automation are disclosed. The framing assemblies include trusses that are attached at the lateral edges thereof by a joist including at least one layer of dimensional lumber to form a substantially rigid framework. Cover panels are positioned over and attached to an inner surface of the framing assembly.

A method, apparatus and computer program product, the method comprising: obtaining a unit description of a unit, and an associated assembly flow, the description comprising information about the unit parts; analyzing the unit description to obtain data for parts of the unit, comprising: determining part measurements; based on the measurements, determining a part type for each part; based on the types, generating a map of the unit; and generating a script for producing instructions for assembling the unit, comprising: repeating for each assembly event on the flow: extracting script commands for the event comprising: repeating for each relevant part or combination associated with the event, the relevant part retrieved from the map: adapting the script commands in accordance with the assembly event and accumulating the script commands as adapted to existing script commands generated on previous iterations of the assembly event and previous assembly events; and storing the script commands.

An automated method and system for manufacturing prefabricated mass timber floor and wall panels, where one or more robots are utilised to assemble (through a combination of picking/placing, gluing and nailing) building parts into a structural panel on an assembly table. A flexible and adaptable method for manufacturing prefabricated mass timber structural panels of different dimensions and make-up. The structural panels comprise a top segmented skin consisting of a number of subpanels, an interstitial layer consisting of a number of interstitial ribs, and a bottom segmented skin consisting of a number of subpanels; the subpanels of one or both layers are connected by glued splines connections and by nailing to the overlapping interstitial ribs.

A hole expansion device includes a cutting portion main, body formed to have a diameter for the cutting portion, main body to be housed within a joint hole and including a cutting blade tool movable in a range from a housed position at which a blade is housed within a diameter for the cutting portion main body to an extended position at which the blade projects out of the diameter, an advancing and retracting member that is constructed to move in an axial direction by an external force and rotate about an axis of the advancing and retracting member, and a link mechanism that converts an advancing and retracting movement of the advancing and retracting member into a rotational movement of the cutting blade tool.
