Automated circuit board assembly positioning system
View Patent ↗An automated circuit board assembly system includes at least one movable circuit board receiver that is equipped with an empty circuit board or a hybrid circuit which is transported towards an uptake location at which components are assembled to the board, and an uptake mechanism positioned at the uptake location which detects the circuit board position in preparation for the assembly process. An alignment device positions the circuit board receiver in a predetermined directional position at the uptake location.
1. A circuit board assembly system, comprising: at least one movable circuit board receiver for supporting a circuit board and having at least one alignment mark; a conveyor for moving the circuit board supported by the at least one movable circuit board receiver to and past an uptake location at which components are assembled on the circuit board; an uptake mechanism for detecting a position of the circuit board in readiness for assembly of the components on the circuit board; an alignment device in which the at least one circuit board receiver is positioned in a predetermined directional position at the uptake location; and at least one search window for detecting the at least one alignment mark to determine that the at least one circuit board receiver is positioned in the predetermined directional position.
2. The circuit board assembly system according to claim 1 , in that the alignment device includes at least one fixed side stop that is operated simultaneously with the at least one circuit board receiver during or after a supply movement by the conveyor.
3. The circuit board assembly system according to claim 2 , in that the alignment device includes at least one positioning element for biasing the circuit board against the at least one side stop.
4. The circuit board assembly system according to claim 3 , in that movement of the at least one circuit board receiver that is initiated by the at least one positioning element results in the supply movement of the at least one circuit board receiver towards the uptake location.
5. The circuit board assembly system according to claim 4 , in that the at least one positioning element is positioned in a fixed way, and in that the at least one positioning element includes at least one inclined lead-in member that runs in a direction transverse of a direction of the supply movement.
6. The circuit board assembly system according to claim 4 , and at least one stop device for limiting the supply movement of the at least one circuit board receiver.
7. The circuit board assembly system according to claim 4 , in that, relative to the supply movement, the uptake location is preceded by a guide channel for rough alignment of the at least one circuit board receiver.
8. The circuit board assembly system according to claim 5 , in that the at least one positioning element is formed from at least one actuator that is arranged to bear upon the at least one circuit board receiver in the direction transverse to the direction of the supply movement.
9. The circuit board assembly system according to claim 5 , in that the at least one inclined lead-in member is elastically flexible.
10. The circuit board assembly system according to claim 5 , in that the at least one inclined lead-in member comprises a spring.
11. The circuit board assembly system according to claim 5 , in that a distance between the at least one inclined lead-in member and the at least one side stop does not exceed a width of the at least one circuit board receiver.
12. The circuit board assembly system according to claim 10 , in that the spring comprises a leaf spring.
