Definitions

  • This invention relates to an assembly line for manufacturing electronic assemblies such as printed circuit boards containing discrete components .
  • the invention is particularly useful for, but not necessarily limited to, maximizing the utilization of the assembly line while at the same time providing maximum flexibility in product mix and volume .
  • the circuit boards are generally conveyed through the assembly line on conveyors .
  • Various assembly processes such as solder stenciling, component mounting and reflow soldering are typically performed.
  • the conveyors are parallel tracks that carry the circuit board through the various stages of assembly, from one station to another. During conveying it is common practice to support the circuit boards along the edges and maintain them in a substantially horizontal plane and isolated from vibration so that the possibility of component misalignment is reduced.
  • the assembly line is usually optimized to enable high efficiency and throughput. This is because of the substantial capital cost of the highly sophisticated and automated equipment employed in modern circuit board assembly lines. A typical line costs two million dollars, and some are as high as ten million dollars. Obviously, one is desirous of operating at highest efficiency in order to realize maximum return on the dollars invested in the equipment, and assembly lines are typically dedicated to a single product so that down time required to reconfigure the assembly line is minimized. On the other hand, the demands of the modern marketplace are such that it is desirous to produce a variety of products in order to satisfy the increasing appetite for electronics that provide features that are tailored to the individual consumer. This means that either several dedicated lines must be employed, or the line must be frequently reconfigured.
  • FIGs . 1 and 2 are schematic views illustrating a dynamically reconfigurable production line in accordance with a preferred embodiment of the invention.
  • FIG. 3 is a schematic view illustrating a placement workcell for a dynamically reconfigurable production line in accordance with an alternate embodiment of the invention.
  • a method of reconfiguring a production line for fabricating printed circuit board assemblies to achieve maximum efficiency and maximum flexibility is disclosed.
  • the production line has one or more placement stations, a reflow oven, a conveyor and a controller.
  • the controller communicates with the various components (placement stations, a reflow oven, a conveyor) of the production line to transfer information related to the state of assembly of some of the printed circuit board assemblies that are being processed.
  • the controller also communicates information related to the status of the various other stations .
  • the operational functionality of one or more of the placement stations, the reflow oven, or the conveyor is altered in response to the communication by the controller .
  • the other remaining modules continue operation unaltered during this step of dynamic reconfiguration.
  • a controller monitors other placement workcells that are downstream. If a downstream workcell is idle, then it sends a signal to the controller that indicates such, and the first placement workcell is dynamically reconfigured. This can occur while the first workcell is in operation, in response to a signal from the controller.
  • the conveyor transports the first electronic assembly from the first placement workcell to the second placement workcell.
  • a second electronic assembly is then conveyed into the first placement workcell, and a second activity is performed on the first electronic assembly in the second placement workcell.
  • the required activity is also performed on the second electronic assembly in the dynamically reconfigured first placement workcell .
  • the controller is responsive to information related to the degree of completion of the activity that is being performed on the various electronic assemblies . In some instances, the operation of the remaining modules continues unaltered during the step of dynamically reconfiguring.
  • the components are placed onto the board by robots or other highly automated machines, such as chip shooters . It should be understood and appreciated that our invention is directed to the use of robots or other machinery as opposed to manual systems where components are placed onto the board by human hands . These various components are then typically attached by reflow soldering them onto the printed circuit board.
  • the production line consists of one or more (typically several) placement machines such as robots.
  • the placement machines are variously referred to as pick-and-place machines, workcells, robots, workstations, placement modules, chip- shooters , etc. in the industry parlance . Each workcell or station typically has a predetermined set of components that can be placed on the PCB.
  • These components are loaded into feeders contained in the workcell, and the robot or placement means selects from the various feeders to place the desired set of components on the PCB.
  • a software program resident in the workcell directs the robot as to which components to select and where to place them on the PCB.
  • the placement of components in each workcell requires a finite period of time, and when the cycle in each workcell is complete, the PCB is then conveyed into the next workcell .
  • a first PCB 15 enters the first workcell 16 and the workcell begins placing components or parts onto the PCB.
  • Another PCB 17 is queued up waiting for the first workcell 16 to finish its cycle. If, during the course of the cycle of placing the various components, another workcell 18, 20 that is downstream (i.e. farther down the production line) is idle or is nearing the end of its cycle, the first workcell is dynamically reconfigured (i.e. the program is altered while it is running) .
  • the cycle of placing components in the first workcell 16 is interrupted and abbreviated so that the PCB 15 can now move into the next, or second, workcell 18, which was idle.
  • the first PCB 15 exits the first workcell 16
  • another, or second, PCB 17 enters the first workcell to have various components placed thereon.
  • the first workcell can either be reconfigured prior to the second PCB 17 entering, or it can remain in the same configuration state as it was when the first PCB 15 left.
  • the second workcell 18 now places the components that were originally destined to be placed on the first PCB 15 prior to the first workcell being dynamically reconfigured.
  • the second workcell 18 typically has a set of components that it normally places on the PCB, and depending on the available time and state of the workcells further downstream, these may or may not be completely placed.
  • the feeders in the second workcell 18 contains a subset of the components found in the first workcell.
  • the principle, heretofore unrealized, is that each workcell is capable of placing some or all of the parts of the workcell that is upstream of itself, and both workcells are capable of being dynamically reconfigured. Thus, the amount of time that any single workcell in the production line is idle is minimized and the efficiency of the line is maximized.
  • it can be immediately alleviated by shifting some of the workload to one or more downstream stations that have idle capacity.
  • some of the workload can be shifted to one or more upstream stations that have idle capacity.
  • the controller is typically a high speed computer that serves to allocate resources amongst the various workcells in order to optimize the efficiency of the production line.
  • the controller 30 may simply pass a signal to the first and second workcells 16, 18 and these workcells then alter the software within their respective systems .
  • the controller can actively modify the software program for each workcell and pass it to the respective workcell for implementation.
  • some type of information on the state of the cycle in each workcell is being passed from the workcells to the controller 30, and other information (e.g. instructions for dynamically reconfiguring) is passed back to these same workcells .
  • the operational functionality of one of the workcells can be dynamically reconfigured while the others continue to operate unaltered.
  • the principles of our invention can also be applied to other segments of the assembly line, for example, to the conveyor 24, the reflow oven 22 or the solder printer.
  • the screen printer and the reflow oven can be dynamically reconfigured to adjust to the dynamic needs of the product mix.
  • the reflow is typically an oven, but can also be a robot with a heating chamber, thus lending itself to quick reconfiguration.
  • U.S. Patent No. 4,840,268 discloses an adjustable width chain conveyor.
  • the conveyor has two parallel and inclined channels within which are mounted a respective continuous chain coupled to a drive. Each chain can slide inwardly or outwardly to accommodate for small variations in widths of circuit boards being conveyed.
  • Still another means of conveying various sized PCBs is to utilize dual, parallel conveyors on the production line. Two conveyors are run side by side through each of the workstations .
  • the conveyor can convey circuit boards of different widths without the need for completely conveying one board through the conveyor before boards of a different width can conveyed.
  • the above preferred embodiment of our novel invention provides a method to process a sequence of electronic assemblies, where the activity being performed on each assembly is different, and where the various workcells can be dynamically reconfigured.
  • Placement workcell 32 comprises placement executor 33, a conveyor 34 and a controller 35.
  • Placement executor 33 includes a component feeder 36 and a component placer 37.
  • Controller 35 couples to control placement executor 33 and conveyor 34.
  • Conveyor 34 is associated with placement executor 33 and conveys PCBs (not shown) from a preceding placement workcell (not shown) to placement workcell 32 or from placement workcell 32 to a placement workcell (not shown) .
  • the preceding or subsequent placement workcell need not be next in sequence with placement workcell 32. For example, there may be one or more intermediate placement workcells between the preceding placement workcell and placement workcell 32.
  • Controller 35 determines one or more operations for executing by placement executor 33.
  • the operations are placement operations in which component placer 37 places components from component feeder 36 onto PCBs.

Abstract

L'invention porte sur un procédé de reconfiguration d'une chaîne de fabrication d'ensembles de circuits imprimés pour obtenir un maximum d'efficacité et de souplesse. La chaîne comporte un ou plusieurs postes (16, 18, 20) de dépose, un four de refusion (22), un convoyeur (24), et un contrôleur (30). Le contrôleur communique avec les composants suscités de la chaîne pour transférer des informations relatives à l'état d'assemblage, de certains des ensembles de circuits imprimés (15, 17, 19) en cours de traitement. Il communique également des informations relatives à l'état des différents autres postes. Les modalités de fonctionnement d'un ou plusieurs postes de dépose du four de refusion, et du convoyeur sont modifiés en fonction des communications du contrôleur. Les autres modules restants continuent à fonctionner sans changement pendant cette étape de reconfiguration dynamique.
