Stud straightener system and method of straightening studs of a wall structure for a modular construction unit

A stud straightener system for straightening studs of a wall structure for a modular construction unit, the stud straightener system comprising:

• a wall frame conveyor configured to move the wall structure thereon, the wall structure having a wall frame comprising the studs and one or more sheathing panels on a top side of the wall frame;
• a stud straightener assembly comprising an actuator assembly having an actuator and a carriage tooling assembly having a clamp tooling assembly and a rotary actuator coupled to the clamp tooling assembly, wherein the carriage tooling assembly is configured to move along the actuator to one or more of the studs, the rotary actuator is configured to rotate the clamp tooling assembly from a horizontal position to a vertical position at each of the one or more of the studs, and the clamp tooling assembly is configured to engage the one or more of the studs to straighten the one or more of the studs,
• wherein the actuator assembly includes a servo motor and gearbox that moves the carriage tooling assembly along the actuator to align the clamp tooling assembly with the one or more of the studs, and
• wherein the clamp tooling assembly includes a clamp having a first clamp member and a second clamp member, wherein the first clamp member is configured to move with respect to the second clamp member to close the clamp about the one or more of the studs to straighten the one or more of the studs.
