Abstract

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.

Claims (36)

1. A stud plate connector system, comprising:

a base plate having a first cam slot and a second cam slot, wherein the second cam slot is approximately a mirror image of the first cam slot;

a first upper cam-follower located within the first cam slot;

a second upper cam-follower located within the second cam slot, wherein the first and second cam-followers hold opposite sides of a first lumber and move the first lumber to contact a second lumber;

a first lower gripper and a second lower gripper for holding the second lumber in a perpendicular direction with respect to the first lumber;

a bonding device located before to the first and second lumber, wherein the bonding device bonds the first and second lumber together; and

a plurality actuators configured to move the first lower gripper and a second lower gripper to hold the second lumber in a perpendicular direction with respect to the first lumber.

2. The stud plate connector system of claim 1 , wherein the first cam slot and the second cam slot form a “Y” shape.

3. The stud plate connector system of claim 1 , wherein the first upper cam-follower and the second upper cam-follower comprise linear rails.

4. The stud plate connector system of claim 1 , wherein the first upper cam-follower and the second upper cam-follower comprise cam-sliders.

5. The stud plate connector system of claim 1 , wherein the first lower gripper and the second lower gripper comprise linear rails.

6. The stud plate connector system of claim 1 , wherein the first lower gripper and the second lower gripper comprise cam-sliders.

7. The stud plate connector system of claim 1 , further comprising:

a first actuator configured to move the first and second upper cam-followers along the first and second cam slots to hold opposite sides of the first lumber and move the first lumber to contact the second lumber.

8. The stud plate connector system of claim 7 , wherein the first actuator is located behind the base plate.

9. The stud plate connector system of claim 7 , wherein the first actuator is located over the base plate.

10. The stud plate connector system of claim 1 , wherein a second actuator of the plurality of actuators is located adjacent to the first lower gripper and a third actuator of the plurality of actuators is located adjacent to the second lower gripper.

11. The stud plate connector system of claim 1 , wherein a second actuator of the plurality of actuators is located behind the base plate and the first lower gripper, and a third actuator of the plurality of actuators is located behind the base plate and the second lower gripper.

12. The stud plate connector system of claim 1 , further comprising an encoder for sensing a position of the first upper cam-follower and second upper cam-follower.

13. A method for joining lumber for a stud plate connector system, the method comprising:

providing a base plate having a first cam slot and a second cam slot, wherein the second cam slot is approximately a mirror image of the first cam slot;

receiving a first lumber via a first upper cam-follower and a second upper cam-follower, wherein the first upper cam-follower and second upper cam-follower are within the first cam slot and the second cam slot, respectively;

receiving a second lumber via a first lower gripper and a second lower gripper;

holding the second lumber in a perpendicular direction with respect to the first lumber using the first lower gripper and the second lower gripper;

moving the first and second upper cam-followers along the first and second cam slots to hold opposite sides of the first lumber and move the first lumber to contact the second lumber;

using a bonding device to bond the first and second lumber together; and

using a plurality actuators to move the first lower gripper and a second lower gripper to hold the second lumber in a perpendicular direction with respect to the first lumber.

14. The method of claim 13 , wherein the first cam slot and the second cam slot form a “Y” shape.

15. The method of claim 13 , wherein the first upper cam-follower and the second upper cam-follower comprise linear rails.

16. The method of claim 13 , wherein the first upper cam-follower and the second upper cam-follower comprise cam-sliders.

17. The method of claim 13 , wherein the first lower gripper and the second lower gripper comprise linear rails.

18. The method of claim 13 , wherein the first lower gripper and the second lower gripper comprise a cam-sliders.

19. The method of claim 13 , further comprising:

using a first actuator of the plurality of actuators to move the first and second upper cam-followers along the first and second cam slots to hold opposite sides of the first lumber and move the first lumber to contact a second lumber.

20. The method of claim 19 , wherein the first actuator is located behind the base plate.

21. The method of claim 13 , further comprising providing an encoder for sensing a position of the first upper cam-follower and second upper cam-follower.
