Abstract

A vehicle assembly system automatically decks and automatically fastens body components to chassis components. The system uses an automatic decking and fastening unit that includes a base with an elevatable platform repositionable relative to the base by at least one actuator. A slidable unit carries a fastener driver, is supported on the elevatable platform, and is repositionable relative to the elevatable platform by at least one other actuator. The slidable unit also carries an arm that is repositionable relative to the slidable unit by yet another actuator. A pair of conveyors are positioned away from the base, are movable relative to the base and carry a pair of vehicle components. The conveyors are cycled so that the vehicle components are positioned relative to one another in a predetermined position, and the actuators are operated to reposition the fastener driver to a position determined by engagement of the slidable unit with one of the vehicle components.

Description

    TECHNICAL FIELD
  • The present invention relates to an automatic vehicle component assembly system, and more particularly, to an automatic decking and automatic fastening (ADAF), apparatus and method that effects automatic decking and automatic fastening of vehicle body components to vehicle chassis components. [0001]
  • BACKGROUND OF THE INVENTION
  • One of the most impressive operations in a vehicle assembly plant involves the marriage of a vehicle body structure to its chassis. For a pick-up truck, this process is generally subdivided into assembly of the passenger cab to the frame and assembly of the utility box to the frame. Commonly used methodology involves a substantial reliance upon manual intervention to accomplish this complex task. In the case of a pick-up cab, a subassembly that can weigh in the neighborhood of 1200 pounds (545 kilograms), is supported by equipment and manually guided into position to align or “justify” the cab relative to the frame, before lowering it onto the frame to effect decking. In addition, manpower is used to guide the machinery that individually applies the fasteners for securing the components together. Automating this type of vehicle assembly process is highly desirable due to the labor intensive and physically demanding operations involved. [0002]
  • SUMMARY OF THE INVENTION
  • Aspects of the present invention involve automation of the process that decks and secures a vehicle body component to its chassis. In accordance with these aspects, an automatic decking and automatic fastening system includes a base with an elevatable unit repositionable relative to the base by at least one actuator. Preferably, the elevatable unit is compliant in the fore-aft direction. This preferred fore-aft compliance is useful in accommodating any experienced chassis carrier stopping error. A cross-car slidable unit is supported on the elevatable unit and is repositionable relative to the elevatable unit by at least one other actuator. Preferably, this other actuator can stop and hold position when an element of the chassis such as a frame bracket has been located. Tooling (referred to in the following detailed description of the preferred embodiment as an ADAF plate), is carried on the slidable unit and is repositionable vertically relative to the slidable unit by yet another actuator. The tooling locates off the chassis element and serves to carry and to justify the body component to the chassis. A fastener driver is preferably carried by a compliant assembly on the slidable unit. This assembly allows the fastener driver to have a preferred compliance in the cross-car and fore-aft directions relative to the slidable unit, and allows the fastener driver, with its own lead in tooling, to locate a mounting fastener. [0003]
  • According to preferred aspects of the present invention, the body element is positioned in space at a predetermined location. The actuators are operated to reposition the tooling to accept and justify the body element to a position determined by engagement of the tooling with the chassis. The justified body element is lowered to the chassis, the tooling is retracted, and the fastener driver advances fastening the body element to the chassis.[0004]

  • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to the drawings, illustrated in FIG. 1 is one fixture, referred to as [0018] ADAF unit 12, of an automatic decking and automatic fastening system 10. Generally, the ADAF unit 12 is operable to position fastener driver 18 relative to a first vehicle component (not shown in FIG. 1), and to position a second vehicle component relative to the first vehicle component. This is accomplished by operation of a plurality of actuators designated as cylinders 14-17, which are pneumatic in the present embodiment. The ADAF unit 12 is described within the application of assembling a pick-up cab to its frame, but is useful in the assembly of many types of vehicle body components to their associated vehicle chassis components.
  • More specifically, ADAF [0019] unit 12 includes a base assembly 20 that is anchored to foundation 19 in a conventional manner. The base assembly 20 includes a horizontal structure 21 that supports vertical riser 22, with a gusset fixed between the two for added rigidity. An elevatable unit 24 is carried by the base assembly 12 and includes a platform 25 and a vertical leg 26 each fixed to another gusset. A pair of bearings 27 and 28 are positioned between the vertical riser 22 and the vertical leg 26 permitting relative vertical movement there-between. The elevatable unit 24 is positioned vertically relative to the base assembly 20 by a joined pair of actuators designated as cylinder 14 and cylinder 15. Cylinder 14 includes an extensible rod that is connected to base assembly 20 and cylinder 15 includes an extensible rod that is connected to elevatable unit 24. By selectively varying the power fluid pressure in cylinders 14 and 15, the vertical position of the elevatable unit 24 relative to the base assembly 20 is automatically varied to carry out the operations of the ADAF system 10.
  • A [0020] slidable unit 30 is carried by the platform 25 and includes a base plate 31 and an upwardly extending vertical arm 32 with a gusset fixed there-between. A slide assembly 34 is positioned between the base plate 31 and the elevatable unit's platform 25. To position the slidable unit 30 in the cross-car direction relative to the vehicle being assembled, the slide assembly 34 includes a pair of bearings 35 and 36 along with an actuator in the form of cross-car cylinder 17 that has an extensible rod connected to the slidable unit 30. To allow positionability of the slidable unit 30 in the fore-aft direction relative to the vehicle being assembled, the slide assembly 34 includes a pair of bearings 38 and 39 along with a well known type of spring centering mechanism 40 that extends between the slide assembly 34 and the elevatable platform 25. Bearings 35, 36, 38 and 39 in combination with cylinders 14, 15 and 17, and centering mechanism 40 enable omnidirectional positionability of the slidable unit 30 including base plate 31, relative to the base assembly 20.
  • The [0021] end effector assembly 65 of the ADAF system 10 includes a power operated fastener driver 18 of a type well known in the art that is carried by a compliant assembly 41 on the slidable unit 30, and exhibits an upwardly facing rotating tool 42 that is disposed within a spring loaded guide 44. The compliant assembly 41 is of a well known type and allows the fastener driver to be compliant in the cross-car and fore-aft directions relative to the slidable unit through the use of elements that are displaceable under force, such as springs. This compliance allows the fastener driver, with its own lead in tooling, to move into alignment while locating the cab mount screw. The rotating tool 42 is selectively positioned along with the slidable unit 30 in an automatic manner. In addition, the fastener driver 18 is operated automatically during procedures of the ADAF system 10. This automatic fastening system for the fastener driver records the product sequence number and all cab mount torques for quality assurance and flags any non conformities for correction to specification.
  • A [0022] decking arm 45 is also carried on the slidable unit 30 and includes tooling, referred to as ADAF plate 46, that is vertically movable relative to the rotating tool 42. Bearings 47 and 48 are positioned between the decking arm 45 and the vertical arm 32 of slidable unit 30. A cylinder 16 extends between slidable unit 30 and decking arm 45 providing the motive force for vertically positioning the decking arm 45 and the ADAF plate 46 relative to platform 25. The ADAF plate 46 justifies the cab to the chassis frame and includes an angled top surface to facilitate locating on the cab 51. When cylinder 16 is retracted, the ADAF plate 46 is positioned relatively close to the rotating tool 42. This allows the cab to be decked to the chassis frame and the fastener driver to re-engage the chassis frame to fasten the cab screws.
  • Referring to FIG. 2, it can be seen that the [0023] ADAF unit 12 is one of two substantially identical mirror- image ADAF units 11, 12 included in the cab to frame marriage station of ADAF system 10. In FIGS. 2-10 the gusset plates of ADAF units 11 and 12 are removed for improved clarity. Additionally, components of ADAF unit 11 that are like those of ADAF unit 12, carry the same numerical designation with the addition of a prime symbol. Above the ADAF units 11 and 12, a marriage transfer 50 supports cab 51, and operates to lower the cab 51 onto the ADAF units 11 and 12. Preferably, a trim conveyor (not illustrated), initially carries the body components and a chassis conveyor 52 carries the chassis component. The trim and chassis conveyors are alternatively shuttled along the same path. The cab and the utility box (not illustrated), are lifted from the trim conveyor and repositioned above the ADAF units 11 and 12 relative to one another in a predetermined position by the marriage transfer 50. Between the ADAF units 11 and 12, chassis conveyor 52, which is of a conventional type such as an automatically guided vehicle, supports a frame 53, and operates to bring the frame 53 into position relative to the ADAF units 11 and 12. In the present process sequence stage, the cab 51 is positioned prior to being lowered, and the frame 53 is positioned between the ADAF units 11 and 12. To initiate an automatic decking and fastening system cycle, a signal to begin prompts operation of the cylinders 15 and 15′, which extend to full stroke as shown, raising the elevatable units 24 and 24′. At this stage cylinders 14, 14′, 16, 16′, 17 and 17′ are fully retracted. In this position the Marriage station is ready to place the cab 51 onto the ADAF units 11 and 12.
  • Referring to FIG. 3, when the [0024] cylinders 15, 15′ are fully extended a signal is sent to prompt cylinders 16, 16′ to extend to full stroke, at which point the ADAF units 11 and 12 are ready to locate the chassis frame. As shown in FIG. 4, when the cylinders 16, 16′ are fully extended and the chassis conveyor is in position, a signal is sent to prompt cross-car cylinders 17, 17′ to extend to a stall condition occurring when ADAF plates 46, 46′ are positioned against chassis frame brackets 55, 56. At the stall position, cylinders 17, 17′ are locked in place. Optionally, movement of the cylinders 15, 15′, 16, 16′, 17 and 17′ may occur simultaneously or in any sequence to effect location of the ADAF units 11 and 12 to the desired position, with the ADAF plates 46, 46′ engaging brackets 55, 56. The sequence depends on the line of attack that is open, which is dictated by the specific shape of the product being married together. The ADAF plates 46, 46′ are prepared to accept the cab 51 from the marriage transfer 50 and justify it to a position determined by engagement of the ADAF plates with the cab and with the brackets 55, 56.
  • Referring to FIG. 5, the next stage involves [0025] marriage transfer 50 lowering cab 51 onto ADAF plates 46, 46′ of the decking arms 45, 45′, which receive and carry the cab 51. In this position, the cab's bearing plates 57, 58 are aligned with the mounts 60, 61 of the frame 53, with the end effectors of the ADAF units 11 and 12 positioned below the mounts 60, 61. Referring to FIG. 6, cylinders 16, 16′ are fully retracted so that the decking arms 45, 45′ lower the cab 51. The bearing plates 57, 58 rest on the mounts 60, 61 respectively, decking the cab 51 to the frame 53. At this point a signal is sent to initiate operation of the fastener drivers 18, 18′ at a slow speed. Referring to FIG. 7, the cylinders 14, 14′ are extended so that the rotating tools 42, 42′ engage the fasteners. As the fastener drivers start to drive the cab screws, the fastener drive torque increases to a level which causes the fastener controlling system to trip to high speed, rapidly driving the fasteners. When a preset torque is reached, the fastener drivers stop rotating and a signal is sent to retract cylinders 14, 14′.
  • Reference is directed to FIGS. 11 and 12 to clarify operation of the end effector tooling. A preferred mechanism for locating the fastener drivers relative to the fasteners is shown in a simplified schematic manner. [0026] Bracket 55 is rigidly connected to frame 53 and is preassembled with a fastener 64. The end effector assembly 65 includes fastener driver 18, spring loaded guide 44, and locator 67. In its initial position, the axis 68 of rotating tool 42 is not aligned with the fastener 64, but is positioned slightly inboard therefrom. As cylinder 14 is extended, the locator 67 engages the side rail of frame 53. Locator 67 includes an angled wall 69 that effects alignment of the rotating tool 42 with the fastener 64 when the terminal end 70 of the locator engages frame 53. The guide 44 includes a flared circular opening 71 to assist in capturing the head of fastener 64 and directing it to rotating tool 42. Initial slow speed rotation of the tool 42 also facilitates capture. During this process, in effect, the tooling is permitted to float by the centering mechanism 41. As the rotating tool 42 drives the fastener 64 home, the guide retracts, compressing a spring that biases the guide outwardly along the rotating tool 42.
  • Continuing with reference to FIG. 8, [0027] cylinders 14, 14′ retract, withdrawing the end effectors 65, 65′. Next, as shown in FIG. 9, cylinders 15, 15′ retract, clearing the decking arms 45, 45′ from the cab 51 and frame 53. Finally, the cross-car cylinders are unlocked and retracted as shown in FIG. 10, so that the ADAF units 11 and 12 are returned to their home positions and readied for another cycle of the ADAF system 10. The conveyor 52 moves the assembled cab 51 and frame 53 out from the automatic decking and fastening system marriage station.
  • Accordingly, automation of the process that decks and secures a vehicle body component to its chassis is provided that eliminates labor intensive operations previously associated with the marriage process. [0028]
