Description
- This application is based on and claims the benefit of U.S. provisional patent application Serial No. 60/255,925, filed Dec. 15, 2000, entitled “CAMERA WITH IEEE 1394 INTERFACE”.
- The electronics assembly industry uses machines such as pick and place machines to automatically pick components from component feeders and place the components upon circuit boards during board assembly. Subsequently, the components themselves are permanently attached to the circuit board at locations where the pick and place machine has deposited them. Due the relatively high speed required for such operations as well as the extremely small-scale of the components themselves, component placement and alignment are extremely important. In order to facilitate advances in component placement and alignment, optical systems and associated processors have advanced accordingly. One common element of a pick and place system is known as the board align image acquisition device. Typically, this image acquisition device resides upon a placement head and is used to essentially image a reference position (also known as a fiducial) on the board. By determining the placement of the head via encoders, or other suitable position measuring means, associated therewith, and determining the position of the fiducial from the image supplied by the board align camera, the relative position of the placement head with respect to the board is precisely known.
- The position of the component to be placed on the placement head is calculated in a similar manner but with a generally upward-looking component align (CA) image acquisition device. The component align image acquisition device generally acquires an image of the component to be placed after it has been picked up by the placement head. The host processor then determines the position of the component on the placement head and knowing the position of the placement head with respect to the board, so manipulates the component to be placed that it is oriented correctly and placed properly upon the board. Thus, a typical pick and place system includes a pair of image acquisition device (board align and component align). Due to the relatively high-speed operation of pick and place machines, there is a relatively large amount of data (both image data and control data) that passes between the host processor and the various image acquisition devices and their associated illuminators. A pick and place system that could accommodate the relatively high data transfer burdens while simultaneously simplifying wiring and reducing costs would be a significant increase in the art. Moreover, if such system could provide data transfer rate head room beyond that which is currently needed and accommodate future scalability, system implementation would be facilitated.
- An electronics assembly system includes an image acquisition system that is coupled to a controller through an improved interface. The coupling facilitates advanced monitoring and control of the image acquisition system. Multiple image acquisition devices can be coupled to the controller over the same interface.
- FIG. 1 is a diagrammatic view of a pick and place machine in which embodiments of the present invention are particularly useful.
- FIG. 2 is a perspective view of a placement head including a board align image acquisition device in accordance with an embodiment of the present invention.
- FIG. 3 is a diagrammatic view of a portion of a pick and place machine in accordance with an embodiment of the present invention.
- FIG. 4 is a system block diagram of an image acquisition system in accordance with an embodiment of the present invention.
- FIG. 1 is a diagrammatic view of a pick and
place machine 100 in accordance with the prior art.Machine 100 includesplacement head 102 upon which are mounted component align (CA)image acquisition device 104,nozzles 106 and board align (BA)image acquisition device 108.Controller 110 is coupled todevices placement head 102 which encoders indicate position ofplacement head 102 along X and Y axes. - FIG. 2 is a perspective view of
placement head 102. As illustrated,placement head 102 includes a pair of pick andplace units 112 each of pick andplace units 112 include anozzle 106 that is adapted to releasably couple a component to be placed such ascomponents 114. Pick andplace units 112 are adapted todisplace components 114 along the Z axis to placecomponents 114 upon a circuit board (not shown). Whilecomponents 114 are releasably held bynozzles 106, relative motion between thenozzles 106 and the component alignimage acquisition device 104 is translated beneathcomponents 114 whileimaging components 114 withdevice 104 allows for determination of the relative orientations ofcomponents 114 with respect to thenozzles 106. FIG. 2 also illustrates board align (BA)image acquisition device 108 disposed proximate an edge ofplacement head 102 and facing downward.Device 108 acquires an image of a reference position marker (fiducial) on the circuit board in order to allow calculation of theplacement head 102 position with respect to the circuit board. - FIG. 3 is a diagrammatic view of a portion of a pick and place machine in accordance with an embodiment of the present invention.
Host 110 is coupled to X and Y encoders (illustrated diagrammatically atreference numerals host 110 is coupled to board alignimage acquisition device 108 viainterface 120.Device 108 is also physically coupled torobot 122 which is used to actuatenozzle 106 to pick upcomponents 114 and place them upon printed circuit board (PCB) 124. As illustrated,board 124 includes a reference position mark, or fiducial, 126. When required, board alignimage acquisition device 108 acquires an image of fiducial 126, and/or additional fiducials, and computes a position ofplacement head 102 with respect toboard 124. While not shown in FIG. 3, a component align image acquisition device is also used to acquire images of the components themselves to calculate component orientation and position such that the components can be accurately placed uponboard 124. Further, board alignimage acquisition device 108 and component alignimage acquisition device 104 typically have associated lighting. Thus, a significant amount of data overhead is created wherein image data fromdevice 108 and/ordevice 104 must be transmitted tohost controller 110. One aspect of embodiments of the present invention is placing one or more of the image acquisition devices (board align, component align, or other suitable devices) upon a bus that accommodates such co-existence without significantly increasing complexity or cost. - One example of such a bus is known as the IEEE 1394-based Digital Camera Specification, Version 1.3, dated Jul. 25, 2000 (Specification) which describes the type of information to be sent between a digital camera and a host over an IEEE 1394 bus. As used herein “Specification” shall include any specification compatible, either presently or backwardly, with the IEEE 1394-based Digital Camera Specification. The 1394 Specification provides for data transmission speeds at 100, 200, and up to 400 megabits per second. While the Specification listed above does not provide features which facilitate the use in pick and place machines, there is an ability provided in the Specification to add additional features. This is done via advanced control and status registers (CSR). A portion of this patent document will make reference to the Specification. Information regarding the Specification may be found on the worldwide web at http:\\www.1394ta.org. Some of the features useful for
device 108 but not currently set forth in the Specification follow. The Specification does not set forth an ability to control four or more illumination channels. In additional to the control of illumination, there are currently no characterization registers available to determine the capabilities of each image acquisition device. Another feature that is not provided by the Specification is the ability to set illumination counters to help determine lifetime of the illuminators themselves. Further, there is currently no storage provided by the Specification for mechanical and optical parameters that could be characterized during calibration. These features and their implementation in embodiments of the present invention will be set forth in greater detail below. - FIG. 4 is a diagrammatic view of BA
image acquisition device 108 in accordance with an embodiment of the present invention.Device 108 couples to host 110 throughport 130 alongSpecification bus 132.Bus 132 is coupled to link andphysical layer controller 134. Preferably, link and physical layer controllers are preferably commercially available devices sold by Texas Instruments under the trade designations TSB42AB4PDT, and TSB41AB1PHP, respectively.Controller 134 is coupled tomicrocontroller 136 andprogrammable logic device 138 throughbus 140. Preferably,bus 140 is a 16-bit 68000 bus.Microcontroller 136 is preferably a microcontroller sold under the trade designation ATmega103L available from Atmel of San Jose, Calif.Microcontroller 136 is also coupled to analog temperature sensor 142, four-channel digital-to-analog converter 144 and CCD and support chip set 146. Preferably,microcontroller 136 is coupled toconverter 144 and chip set 146 through a serialperipheral interface bus 148. Throughbus 148, CCD and support chip set 146 can acquire and provide an image tomicrocontroller 136. During acquisition of such an image, illuminators 150 are engaged in response to control signals frommicrocontroller 136 and/orprogrammable logic device 138. Illuminators 150 can include a darkfield illuminator, and/or a brightfield illuminator. One of the primary features of adaptingdevice 108 for operation withSpecification bus 132 is that additional image acquisition devices and 1394 bus-compatible devices can be coupled to the same bus. This reduces system wiring and complexity while also facilitating standardization and implementation. - The following description sets forth a preferred embodiment in such detail that specific data values for specific control and status registers in the1394 specification are provided.
