text: a workstation 10 according to the present invention includes a multiple robotic workstation with multiple fixtures for processing multiple workpieces 12 and 14 of the same or different configurations sequentially or concurrently . the workstation 10 of the present invention has at least two fixtures , a first fixture 16 and a second fixture 18 . the workstation 10 includes multiple robots located interposed between the fixtures 16 , 18 . in a preferred embodiment of the present invention , the workstation 10 has three robots 20 , 22 and 24 positioned in between the two fixtures 16 , 18 with overlapping areas of reach between adjacent robots . the fixtures 16 and 18 are operable to hold workpieces 12 and 14 , respectively , in position for a processing operation . preferably , the fixtures 16 and 18 located at workstation 10 are capable of positioning a plurality of workpiece nests corresponding to the desired body style and model to be processed through the workstation 10 . in the preferred configuration , each of the fixtures 16 and 18 include four different workpiece nests positioned on four major surfaces of a fixture having a rectangular or square cross - section and rotatable about a horizontal axis a to position one of the four major surfaces in an upright , ready position for receiving workpieces to be processed at the workstation 10 . the robots 20 , 22 and 24 are positioned between fixtures 16 and 18 with overlapping areas of reach between adjacent robots , preferably so that at least two robots can reach all areas of the workpiece to be processed . the robots 20 , 22 and 24 are independently movable with respect to each other . also , the processing robots 20 , 22 and 24 are capable of performing various independent work cycles at each fixture . as used herein , “ work cycle ” refers to a particular quantity and configuration of processing operations on a part 12 or 14 . in a preferred embodiment of the workstation 10 , three robots 20 , 22 and 24 are positioned between the fixtures 16 , 18 . however , the present invention can be practiced with more than three robots . by way of example and not limitation , the robots 20 , 22 and 24 can be welding robots . each robot can perform welding operations at both fixtures 16 and 18 . the robots 20 , 22 and 24 are disposed between fixtures 16 and 18 so that each robot can perform welding operations at programmed areas of the fixtures 16 and 18 . by way of example and not limitation , as shown in fig1 robot 24 can be used to perform welding operations at one end of fixture 18 and one end of fixture 16 , while robot 20 can be performing welding operations at the other end of fixture 18 and the other end of fixture 16 . in such an embodiment of the present invention , robot 22 can be used to perform welding operations in the middle of fixture 16 and the middle of fixture 18 . further , the robot 22 can also be used for welding operations at either end of fixture 16 and fixture 18 . by way of example and not limitation , if part 12 requires relatively numerous welding operations at end 26 and part 14 requires numerous welding operations at end 28 , robots 22 and 24 can each be responsible for a portion of the total number of welding operations required for both ends 26 and 28 of the parts 12 and 14 . the workstation 10 of the present invention provides flexibility in distributing the relative work loads among the robots 20 , 22 and 24 . it is desirable in the present invention to provide a workstation 10 for performing welding operations on multiple workpieces 12 and 14 by multiple robots 20 , 22 and 24 while enhancing the overall efficiency of the workstation 10 . the workstation 10 is operable to perform welding operations on different components simultaneously or sequentially . by way of example and not limitation , part 14 can be an automotive floor pan ( not shown ) while part 12 can be an automotive body side assembly . these different styles of workpieces can be simultaneously processed at the workstation 10 . furthermore , the operation of the robots 20 , 22 and 24 can be synchronized to process different workpieces . the floor pan of this example generally requires a greater amount of time to load and setup for welding than a right hand body side assembly . however , the right hand body side assembly requires a greater number of welding operations than a floor pan . workstation 10 according to the present invention , can begin welding the right hand body side assembly with the welding robots 20 , 22 and 24 as soon as the right hand body side assembly is loaded onto fixture 16 , while the floor pan is being loaded into fixture 18 and set up for welding . one or more of the welding robots 20 , 22 and 24 can be repositioned once the floor pan has been loaded onto the fixture 18 and setup to weld a first series of welds , such as to attach brackets to the floor pan . after welding the brackets to the floor pan , the one or more robots can return to welding the right hand body side assembly , while additional components are set up with respect to the floor pan prior to returning for a second series of welds . for workpieces that require additional loading after one or more welding operations , the welding robots 20 , 22 and 24 can move between the fixtures while the additional loading occurs and return to the workpiece when loading is complete . the workstation 10 can also be positioned adjacent to an identical workstation 10 a . as shown in fig1 two workstations 10 , 10 a can be positioned adjacent to each other on an automotive assembly line . in such a configuration , transfer robots 30 and 32 can move workpieces from one fixture at one workstation 10 to the next workstation 10 a for processing by robots 20 a , 22 a , and 24 a . the transfer robots 30 and 32 can grasp the respective workpieces at appropriate locations for lifting the workpieces out of the fixtures 16 , 18 at the first workstation 10 and positioning the workpieces at the fixtures 16 a , 18 a at the second workstation 10 a . the transferring of workpieces between workstations 10 , 10 a can also be set to perform a processing operation . robot 38 shown in phantom in fig1 can be positioned above and between the two workstation 10 , 10 a for applying a sealant or an adhesive to the workpiece while being held by one of the transfer robots 30 , 32 during movement between fixtures 16 , 16 a and 18 , 18 a respectively . by way of example and not limitation , transfer robot 30 can grasp the part 12 from end 26 , lift the part 12 out of the fixture 16 at the first workstation 10 , hold the part 12 in an elevated position between the workstations 10 , 10 a , and allow the robot 38 to apply a sealant or an adhesive to the part 12 before the part 12 is loaded onto the fixture 16 a at the second workstation 10 a . the workstation 10 of the present invention can also include an electronic control means 40 . the electronic control means 40 can control the position of the welding robots 20 , 22 and 24 according to programmed repetitive movements . the electronic control means 40 can include a central processing unit 42 . the central processing unit 42 can receive a signal corresponding to the configuration of the respective workpieces to be worked on next , and the number and position of welds to be performed on the workpiece . the central processing unit 42 is operable to receive a signal relating to the configuration of the workpieces to be loaded next onto fixtures 16 and 18 , respectively . this information is used to recall the programmed repetitive movement for the robots to accomplish the desired welding operations to be performed to control the position of the welding robots 20 , 22 and 24 during the welding cycle . an infinite variety of workpieces can be processed with various loading times , preparation times , and welding times according to the present invention . the present invention provides a workstation 10 having multiple processing robots 20 , 22 , 24 and multiple fixtures 16 , 18 for processing multiple workpieces 12 , 14 sequentially or simultaneously at an improved rate of workstation efficiency . while the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment , it is to be understood that the invention is not to be limited to the disclosed embodiments but , on the contrary , is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims , which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law .
