Description

  The present invention relates to an apparatus for supporting an attachment work when manually attaching another part to a vehicle body panel which is a base body in an automobile assembly process, and in particular, directly indicates an attachment position of a specific part on the vehicle body panel. On the other hand, the present invention relates to an attachment work support device having a function of detecting the presence or absence of a part after the attachment work.

  For example, in a part mounting process in an automobile door assembly line, a door panel that has been automatically transported in a horizontal posture is positioned and clamped with a predetermined jig, and then the door panel is adjusted to a posture suitable for component mounting work. It is made to stand or stand up, and with this state, it is used for the part mounting work by the manual work of the worker who stands by on the line side. The purpose of erecting or erecting the door panel is mainly to reduce the physical burden on the operator by making the door panel itself face the operator waiting on the line side. And the door panel which finished the installation operation | work of a specific component is automatically conveyed to the next process, after returning to an original horizontal attitude | position again.

  In such a component mounting process, for further workability support, the component mounting position is directly indicated to the door panel in a standing posture by an optical component mounting position indicating device such as a laser pointer, for example. In the next process, a component presence / absence detection device such as an ultrasonic sensor is arranged to inspect whether or not a predetermined component is correctly attached at a normal position of the door panel.

For example, the component mounting position indicating device described in Patent Document 1 is used, and similarly, the same technology as that described in Patent Document 2 is used as the component presence / absence detecting device.
JP-A-9-275605 (FIG. 1) JP 2000-171557 A (FIG. 2)

  However, in an assembly facility such as that described above, if an inspection of the component mounting position and the presence / absence of a component is performed using an optical or ultrasonic device when the door panel is in an upright or standing state, the door panel is moved from the operator side to the door panel. Since it is necessary to irradiate a light beam or the like at a substantially right angle toward the working space, both the component mounting position indicating device and the component presence / absence detecting device must be arranged on the working space side where the worker stands. It is not preferable because it is remarkably restricted and workability deteriorates.

  In addition, while the door panel is in an upright or standing state, while only instructing the part mounting position, the door panel after mounting the part is inspected for the presence or absence of the part at the stage when the door panel returns to the horizontal state or in the next process. In this case, it is necessary to separately provide a component attachment position indicating device and a component presence / absence detection device, which inevitably increases equipment costs.

  The present invention has been made paying attention to such a problem, and in particular, improves the workability by eliminating the constraints on the work space of the worker, and at the same time, substantially includes only a single distance measuring device within the same process. Thus, it is an object of the present invention to provide an attachment work support device which can inspect the parts attachment position and check the presence of the parts after the attachment.

  The invention according to claim 1 is a component suitable for attaching another part attached to the body panel after the body panel carried in a substantially horizontal loading / unloading posture is positioned and clamped on the work cradle. Standing device that raises the vehicle body panel to the mounting work posture, an optical part mounting position indication function that directly indicates the part mounting position to the vehicle body panel in the component mounting work posture, and the carry-in / out posture again after completion of the part mounting work The vehicle body panel has a component presence / absence detection function for detecting the presence / absence of a mounting component, and an optical distance measuring device that irradiates a light beam toward the vehicle body panel in a certain direction.

  And, at least a part of the work cradle for positioning and clamping the vehicle body panel is configured to be rotatable between the vehicle body panel and the carry-in / out posture position of the vehicle body panel and the component mounting work posture position. Regardless of whether it is in the in-orientation position or the component mounting position, the indication point for indicating the component mounting position on the optical axis of the light beam emitted from the distance measuring device in a fixed direction and the presence or absence of the mounting component The detection point at the time of detection is set to be positioned together.

  Therefore, according to the first aspect of the present invention, at least a part of the work cradle for positioning and clamping the vehicle body panel can be rotated together with the vehicle body panel between the carry-in / out posture position of the vehicle body panel and the component mounting work posture position. By configuring, the degree of freedom of the posture change of the vehicle body panel between the loading / unloading posture position and the component mounting work posture position is more constrained than before, and the posture change amount of the vehicle body panel between the two positions is relatively Becomes smaller.

  As a result, it is assumed that a single optical distance measuring device will be used to indicate the mounting position of the component and the inspection for the presence or absence of the mounting component, and the distance measuring device is installed at a position that does not interfere with the work space. If the light beam is emitted from the distance measuring device in a fixed direction regardless of whether the vehicle body panel is in the loading / unloading posture or the component mounting posture, the component mounting position is indicated on the optical axis of the common light beam. And the presence / absence of attachment parts can be detected in the same process.

  According to the invention described in claim 1, in addition to being able to perform the instruction of the component mounting position by the optical distance measuring device and the inspection of the presence or absence of the component after mounting in the same process without impairing workability, Since an optical distance measuring device is commonly used for instructing the part mounting position and inspecting the presence or absence of the part after mounting, it is possible to save space and reduce equipment costs.

  1 and 2 are views showing a preferred embodiment of an attachment work support device according to the present invention, in which a horizontally-long rectangular sheet-like component P is manually attached as an attachment component on the inner surface of a door panel (door outer panel) D of an automobile. The example in the case of attaching by work is shown.

  As shown in the figure, in the process of attaching the sheet-like component P, a plurality of, for example, two gauge posts 2 and 3, each serving as a work cradle, are erected on the jig base 1. A door panel D as a vehicle body panel is positioned and mounted on the gauge posts 2 and 3 with reference to the receiving surfaces 2a and 3a.

  Below the door panel D to be positioned on the gauge posts 2 and 3, a conveyor belt conveyor 4 and an upright device 5 are disposed. The belt conveyor 4 can be moved up and down by a lifter (not shown), and the door panel D to be attached to the component in the lifted-up state has been carried into the process from the previous process in the substantially horizontal loading / unloading posture P1 and has been conveyed. It has a function of transferring the door panel D to the gauge posts 2 and 3 by a lift-down operation. Similarly, the door panel D after the sheet-like component P is attached has a function of lifting up from the gauge posts 2 and 3 in the same carry-in / out posture P1 and carrying it out to the next process.

  On the other hand, the standing device 5 includes an upright air cylinder 7 erected on the jig base 1 via a bracket 6, and a support finger 8 swingably attached to the tip of a piston rod of the air cylinder 7. And a plurality of rubber rollers 9 attached to the support fingers 8. Then, based on the extending operation of the air cylinder 7, as described later, the door panel D positioned in the loading / unloading posture P1 on the gauge posts 2 and 3 is suitable for mounting the sheet-like component P, that is, the component mounting operation. The robot can stand up to the posture P2.

  Here, among the plurality of gauge posts 2 and 3, the clamp device 10 is attached to the shorter gauge post 3. The clamp device 10 forms a part of the gauge post 3 and is attached to the upper end of the gauge post 3 via a pin 11 so as to be swingable and to be mounted on the clamp base 12 so as to be rotatable. The swing-type clamp arm 13 and the clamp cylinder 14 that is also mounted on the clamp base 12 and rotates the clamp arm 13 are formed. The clamp device 10 is capable of swinging the entire clamp device 10 around the pin 11 regardless of whether the clamp arm 13 is in a clamped state or an unclamped state. The door panel D positioned on the gauge posts 2 and 3 is clamped at P1.

  That is, since the clamp device 10 can swing and swing, the door panel D positioned and clamped on the gauge posts 2 and 3 has the position of the loading / unloading posture P1 and the position of the component mounting work posture P2 (standing posture position). The posture can be changed between. Thus, the gauge post 3 itself does not have a receiving surface, and the receiving surface 3 a is formed on the clamp base 12 that is swingably mounted on the upper end of the gauge post 3. Further, the limit switch 15 detects whether or not the clamp device 10 has stood up to the component mounting work position P2 together with the door panel D.

  A support frame 16 having a large height is erected on the jig base 1, and a pair of optical distance measuring devices 17, 18, for example, are mounted close to the tip of the support frame 16. Yes. These distance measuring devices 17 and 18 irradiate the laser beam Lb in a fixed direction toward the door panel D regardless of whether the door panel D is in the loading / unloading posture P1 or the component mounting posture P2. It has become. That is, regardless of whether the door panel D is in the carry-in / out posture P1 or the component mounting posture P2, the direction of the optical axis of the laser beam Lb irradiated toward the door panel D is always set to be constant. In addition, the beam spot B1 of the laser beam Lb on the door panel D in the component mounting work posture P2 and the beam spot B2 of the laser beam on the door panel D in the loading / unloading posture P1 are both on the common optical axis. Is set to be located.

  More specifically, both distance measuring devices 17 and 18 irradiate a laser beam Lb parallel to each other on the door panel D in the component mounting work posture P2, and as shown in FIG. The distance measuring device 17 uses the beam spot B1 of the laser beam Lb on the door panel D to determine the end point (position of a specific corner edge portion of the sheet-like component P) of the attachment position of the sheet-like component P to be attached to the door panel D. I will tell you. Similarly, the other distance measuring device 18 uses the beam spot B11 of the laser beam Lb on the door panel D to indicate the direction (direction) of the attachment position of the sheet-like component P to be attached to the door panel D. That is, since the sheet-like component P to be attached to the door panel D is horizontally long as shown in the figure, the position of the corner edge portion of the sheet-like component P on one side of the sheet-like component P is long. By irradiating another beam spot B11 of the laser beam Lb at a predetermined distance from the beam spot B1 that instructs the sheet, it is instructed to attach the sheet-like component P in a horizontally long shape.

  On the other hand, in a state where the door panel D to which the sheet-like component P is attached has returned from the position of the component attachment work posture P2 to the position of the carry-in / out posture P1, as shown in FIG. The beam spot B2 of the laser beam Lb is applied to the central portion of the sheet-like component P attached to the door panel D, and the distance measuring device 18 captures the reflected light to determine whether the sheet-like component P is present on the door panel D. It comes to detect.

  As described above, one distance measuring device 17 has a function of instructing the attachment position of the sheet-like component P on the door panel D, while the other distance measuring device 18 is provided on the door panel D. As one form of the attachment position of the sheet-like component P, it has a function of instructing its direction (attachment direction) and a function of detecting the presence or absence of the sheet-like component P on the door panel D.

  Here, as shown in FIGS. 1 and 2, at the front end of the support frame 16, independent linear motion type vehicle type switching devices 19 and 20 and rotary type vehicle type switching devices 21 and 22 are provided for each of the distance measuring devices 17 and 18. The distance measuring devices 17 and 18 are mounted via these two types of vehicle type switching devices 19 and 20 and 21 and 22.

  The rotary vehicle type switching devices 21 and 22 are devices in which the distance measuring devices 17 and 18 rotate at a predetermined angle in accordance with the forward / reverse operation of the rotary cylinder 24 mounted on the bracket 23. For example, FIG. , 2, the irradiation direction of the laser beam Lb from each distance measuring device 17, 18 can be switched with respect to each door panel D in the mixed flow production mode of A car and B car of different car types. . On the other hand, the direct-acting vehicle type switching devices 19 and 20 have a predetermined stroke while the mounting plate 26 connected to the piston rod is guided by the guide rod 27 based on the expansion and contraction operation of the direct-acting air cylinder 25. And shifts horizontally. The mounting plate 26 is equipped with rotary distance-changing devices 21 and 22 together with the distance measuring devices 17 and 18 via the bracket 23, so that a mixed flow production mode for the A and B vehicles as described above. The irradiation direction of the laser beam Lb from each of the distance measuring devices 17 and 18 can be shifted and switched with respect to each door panel D in the horizontal direction.

  Here, as shown in FIG. 2, a vehicle type switching type transport stopper 28 and a panel arrival sensor 29 are provided in the attachment process of the sheet-like component P, and the attachment target of the sheet-like component P is provided as described above. When the door panel D is carried into the attachment process of the sheet-like part P by the belt conveyor 4, the door panel D is brought into contact with the conveyance stopper 28 and stopped, and the arrival (sitting) of the door panel D is determined by the panel. The arrival sensor 29 detects it. Similarly, the panel passing sensor 30 is disposed on the carry-out side of the attachment process of the sheet-like component P, and the door panel D after completion of the attachment of the sheet-like component P is correctly carried out from the attachment process toward the next process. It is to detect whether or not.

  According to the attachment work support device configured as described above, as shown in the flowchart of FIG. 3 in addition to FIGS. 1 and 2, the order of the vehicle types of the door panel D to be carried into the attachment process of the sheet-like component P is not shown. It is managed by a higher-level production management device, and therefore, which type of vehicle door panel D is carried into the attachment process is known before the actual door panel D is carried in. Prior to the actual loading of the door panel D, the position of the transport stopper 28, the panel arrival sensor 29 or the distance measuring devices 17 and 18 is switched to the position of the corresponding vehicle type in response to the above vehicle type information (step of FIG. 3). (See S18 and S19).

  When the door panel D of the corresponding vehicle type is carried into the attachment process by starting the belt conveyor 4 in the lift-up state (steps S1 and S2), the door panel D is brought into contact with the conveyance stopper 28 and stopped. The belt conveyor 4 stops when the arrival sensor 29 detects the arrival of the door panel D (steps S3 and S4). Then, when the belt conveyor 4 is lifted down, the door panel D is transferred to the plurality of gauge posts 2 and 3 and positioned (step S5). At this time, each clamping device 10 is in an unclamped state.

  When the door panel D is positioned on the gauge posts 2 and 3, the clamping device 10 on the gauge posts 2 and 3 performs a clamping operation, and presses a part of the door panel D between the clamp arm 13 and the clamp base 12. Clamping and positioning clamping is performed with reference to the clamp base 12 (step S6).

  When the door panel D is positioned and clamped, the air cylinder 7 as the standing device 5 is extended, and the door panel D is rotated and displaced together with the clamp device 10 around the pin 11 on the gauge post 3 side. Is positioned in the component mounting work posture P2 (step S7).

  In this state, the distance measuring devices 17 and 18 irradiate the door panel D in the component mounting work posture P2 with the laser beam Lb, and as shown in FIG. 2, the sheet-like component is generated by the beam spot B1 of the one laser beam Lb. The end point of the position where P is to be attached is instructed, and at the same time, the direction (orientation) of attaching the sheet-like component P is instructed by the beam spot B11 of the other laser beam Lb (step S8).

  Waiting for such an instruction, the worker M waiting on the line side manually attaches the sheet-like component P to the door panel D with a predetermined fixing means (step S9). That is, since the sheet-like component P to be attached to the door panel D is a horizontally long rectangular shape, the operator attaches the corner edge portion of the sheet-like component P so as to match the beam spot B1 of one laser beam Lb, At the same time, they are mounted so that the beam spots B1 and B11 of the two laser beams Lb are positioned on the common long side.

  When the attachment of the sheet-like component P to the door panel D is completed, the worker M presses a push button switch (not shown) prepared on the line side after being separated from the equipment by a predetermined distance (step S10). The distance measuring devices 17 and 18 are still irradiated with the laser beam Lb.

  Then, the air cylinder 7 of the standing device 5 is contracted to return the door panel D to which the sheet-like component P is attached to the original loading / unloading posture P1 (step S11). That is, the door panel D returns to the state of being clamped with reference to the gauge posts 2 and 3 again.

  When the door panel D returns to the carry-in / out posture P1, the relative positional relationship between the laser beam Lb irradiated from the distance measuring devices 17 and 18 and the door panel D changes, and the laser beam irradiated from at least one of the distance measuring devices 18 is changed. Lb is directed to the center of the sheet-like component P after mounting, and the beam spot B2 of the laser beam Lb is located at the center of the sheet-like component P. Then, the distance measuring device 18 receives the reflected light from the sheet-like component P based on the irradiation with the laser beam Lb, photoelectrically converts it and detects it as the distance from the distance measuring device 18 to the sheet-like component P. By comparing with the reference value set in advance above, the suitability, that is, the presence or absence of the sheet-like component P is detected (step S12). In this case, if the presence of the sheet-like component P is not recognized, the operator M is notified with an alarm that the sheet-like component P is not attached (step S13).

  Thereafter, the clamp device 10 performs an unclamping operation to release the door D panel (step S14), while the belt conveyor 4 performs a lift-up operation, whereby the door panel D to which the sheet-like component P is attached becomes the gauge post 2, 3 is lifted up (step S15), and the conveyor 4 is further activated, whereby the door panel D is carried out to the next process (steps S16 and S17). Note that whether or not the door panel D to which the sheet-like component P has already been attached has been correctly carried out is detected by the panel passage sensor 30 shown in FIG.

  Before the next door panel D is put on the gauge posts 2 and 3, the vehicle type information is received from the upper production instruction device, and the distance measuring devices 17 and 18, the conveyance stopper 28, or the panel arrival sensor 29. The position is selectively switched (steps S18 and S19). Thus, a series of processes relating to the attachment of the sheet-like component P is completed, and thereafter the same operation is repeated.

  As described above, according to the present embodiment, when the loading / unloading posture P1 of the door panel D and the component mounting work posture P2 are compared, the posture change is performed by a rotational motion with the pin 11 on the gauge post 3 side as the rotation center. By restraining, the posture change amount is made as small as possible, and as a result, the irradiation direction of the laser beam Lb from the distance measuring devices 17 and 18 is the component loading / unloading posture P1 and the component mounting work posture P2 of the door panel D. In other words, it is possible to respond to the indication of the attachment position of the sheet-like component P and the presence / absence detection of the component P after the attachment. Therefore, it is not necessary to provide the distance measuring devices 17 and 18 on the work space side of the worker M, and workability is not hindered.

  Moreover, since the distance measuring devices 17 and 18 are commonly used for indicating the attachment position of the sheet-like component P and detecting the presence or absence of the component P after the attachment, the number of sensors required is reduced. As a result, simplification of equipment and cost reduction can be achieved.

  FIG. 4 shows a second embodiment of the present invention, and the structure of the standing device 5 is different from that of the first embodiment. In FIG. 4, the same reference numerals are given to the parts common to the first embodiment.

  That is, as apparent from comparison between FIG. 4 and FIG. 1, in the second embodiment, the rotary cylinder 31 is employed as the actuator of the standing device 5, and the swing arm 32 rotated by the rotary cylinder 31 is used. A support finger 8 is attached to the tip, and the rest is the same as that shown in FIG. In the second embodiment, the same effect as that of the first embodiment can be obtained.

  FIG. 5 shows a third embodiment of the present invention, in which the indication position of the attachment position of the sheet-like component P in the component attachment work posture P2 of the door panel D and the presence / absence detection of the sheet-like component P in the loading / unloading posture P1 are shown. This shows an example in which the detection point for cannot be set on the optical axis of the common laser beam Lb. In FIG. 5, parts that are the same as those in the first embodiment are given the same reference numerals.

  That is, as shown in FIG. 5, the support frame 16 has an optical path switching for switching the irradiation direction of the laser beam Lb from the distance measuring devices 17 and 18 to the door panel D between the component mounting work posture P2 and the carry-in / out posture P1. This is different from the first embodiment in that a fixed reflection mirror 33 and a movable reflection mirror 34 are provided as means. The fixed reflection mirror 33 is fixed to the tip of an auxiliary frame 35 extending from the support frame 16, while the movable reflection mirror 34 can be moved forward and backward by a mirror set cylinder 36 attached obliquely to the support frame 16. It is supported. More specifically, although the movable reflection mirror 34- is fixed to the bracket 37, the bracket 37 moves back and forth in accordance with the expansion / contraction operation of the mirror set cylinder 36. The position can be selectively switched.

  In the third embodiment, when the attachment position of the sheet-like component P is instructed to the door panel D in the component attachment work posture P2, the movable reflection mirror 34 is advanced as shown in FIG. In addition, the laser beam Lb is irradiated from the distance measuring devices 17 and 18. The laser beam Lb emitted from the distance measuring devices 17 and 18 is reflected by the movable reflecting mirror 34 and the fixed reflecting mirror 33, and then irradiated with the beam spots B1 and B11 of the reflected laser beam Lb1 as shown in FIG. Similarly, the attachment position of the sheet-like component P is instructed on the door panel D.

  On the other hand, when detecting the presence or absence of the sheet-like component P in the door panel D returned to the carry-in / out position P1, the reflection mirror 34 is moved backward. As a result, the laser beam Lb emitted from the distance measuring devices 17 and 18 is directly irradiated onto the door panel D in the carry-in / out posture P1, and the presence or absence of the sheet-like component P is detected by the beam spot B2 of the laser beam Lb. The

  As described above, according to the third embodiment, the same effect as that of the first embodiment can be obtained, and the support point at the component mounting position and the detection point for detecting the presence or absence of the component can be obtained. Even if it cannot be set on the optical axis of the common laser beam Lb, there is an advantage that the intended purpose can be achieved without increasing the number of sensors.
