Connector press
View Patent ↗A connector press provides for learning a specified connector pressed position, adjusting a force based threshold, and simultaneously pressing multiple connector types into a circuit board. The force based threshold may be adjusted via a slider bar on a user interface. The specified pressed position may be learned by measuring and storing a position or force value, upon the user causing the press to press the connector into a circuit board. A total force based threshold may be determined in order to simultaneously press multiple connector types. The total force based threshold may be based upon quantities and pressing forces of each of the connectors types. Further, the press may provide near capacity pressing force, even with an asymmetrical load, by including linear guides.
1. A press for pressing a connector into a circuit board, the press comprising:
a linear motion source comprising a motor and a motion converter that converts rotational motion of the motor to linear motion;
a platen mechanically coupled to the linear motion source;
a first linear guide and a second linear guide mechanically coupled to opposite sides of the platen to compensate for asymmetric forces about the center of the platen; and
a processor communicatively coupled to the motor, wherein the processor deactivates the motor in response to a predetermined criterion.
2. The press as recited in claim 1 , wherein the motor comprises a servo motor and the motion converter comprises a ball screw.
3. The press as recited in claim 1 , wherein the first linear guide and the second linear guide each comprise a linear bearing.
4. The press as recited in claim 1 , further comprising a frame mechanically coupled to the first linear guide and the second linear guide.
5. The press as recited in claim 4 , wherein the frame is generally shaped to define an area for connector pressing and comprises a first side and a second side, the first linear guide is mechanically coupled to the first side, and the second linear guide is mechanically coupled to the second side.
6. The press as recited in claim 1 , wherein the predetermined criterion is a force based threshold.
7. The press as recited in claim 6 , wherein the predetermined criterion is a force threshold.
8. The press as recited in claim 7 , wherein the force threshold is a desired force exerted by the platen on the connector.
9. The press as recited in claim 6 , wherein the predetermined criterion is a force-distance ratio threshold.
10. The press as recited in claim 9 , wherein the force-distance ratio threshold is an increase in a force exerted by the platen on the connector in relation to a distance by which the platen moves in relation to the connector.
11. The press as recited in claim 9 , wherein the force-distance ratio threshold is an increase in a force exerted by the platen on the connector in relation to a period of time.
12. The press as recited in claim 1 , wherein the predetermined criterion is a position of the platen in relation to the circuit board.
13. The press as recited in claim 1 , further comprising a load cell communicatively coupled to the processor, wherein the load cell generates an output representative of a force exerted on the connector by the platen.
14. The press as recited in claim 1 , wherein the platen is a first platen, the press further comprises a second platen that opposes the first platen and supports the circuit board, the first platen moves in relation to the second platen in response to the linear motion, and the connector is positioned between the first and second platens.
15. The press as recited in claim 1 , further comprising a gantry mounted on the first and second linear guides, wherein the platen is mounted on the gantry.
16. The press as recited in claim 1 , wherein the processor:
receives an indication that the platen has been positioned at a position wherein the connector is pressed into the circuit board;
determines a value corresponding to the position; and
stores the value.
17. The press as recited in claim 16 , wherein the processor subsequently causes the platen to move approximately to the position based on the value as another connector is pressed into the circuit board.
18. The press as recited in claim 16 , wherein the value is an approximate value of a force exerted on the circuit board by the platen.
19. The press as recited in claim 16 , wherein the value is an approximate value of a position of the platen.
20. The press as recited in claim 7 , wherein the connector is a first type of connector and the force threshold is a combined force required to simultaneously press the first type of connector and a second type of connector into the circuit board.
21. The press as recited in claim 1 , wherein the connector is a first connector, the platen is a first platen, and the press further comprises: (i) a tool comprising a second platen configured for mounting on the first platen; and (ii) a first and a second fixture, wherein the first fixture has a first height, the second fixture has a second height different than the first height, and the first and second fixtures simultaneously press the first connector and a second connector having a height different than a height of the first connector, respectively, into the circuit board.
