There is a risk.

An object of the present invention is to provide a work mounting device capable of mounting a work in a posture corresponding to a posture of a vehicle body without wearing parts.

(1) The work mounting device (for example, the battery unit mounting device 1 described later) according to the present invention works on the vehicle body (for example, the bottom portion 91 described later) from the bottom portion (for example, the bottom portion 91 described later) side of the vehicle body (for example, the vehicle body 9 described later). , The battery unit 3) described later is mounted, and the pallet on which the work is placed (for example, the pallet 5 described later) and the lifting device for raising and lowering the pallet on the bottom side (for example, raising and lowering described later). The device 6), a tilting mechanism that tilts the pallet with respect to the vehicle body (for example, the tilting mechanism 7 described later), and a contactor that comes into contact with the vehicle body when the pallet is lifted by the lifting device (for example, the vehicle body described later). The contact pad 526,536,546,556) and a lock mechanism (for example,) that fixes the inclination angle of the inclination mechanism in a state where the contactor is in contact with the vehicle body and the pallet is in the mounting posture with respect to the bottom portion. The front lock mechanism 75 and the rear lock mechanism 77), which will be described later, are provided, and the contactor can be retracted from the vehicle body after being in contact with the vehicle body and having the inclination angle fixed by the lock mechanism. It is a feature.

(1) In the work mounting device according to the present invention, when the pallet is raised by the elevating device on the bottom side of the vehicle body, the contactor comes into contact with the vehicle body, whereby the posture of the pallet with respect to the vehicle body changes according to the posture of the vehicle body at that time. When the pallet changes and the posture of the pallet with respect to the vehicle body becomes a predetermined mounting posture, the tilt angle of the tilt mechanism is fixed by the lock mechanism. Further, in the present invention, when the inclination angle is fixed by the lock mechanism, the contactor can be retracted from the vehicle body. Therefore, in the present invention, after the contactor is retracted from the vehicle body, the pallet is further raised while being maintained in the mounting posture, so that the work can be mounted on the vehicle body in a posture corresponding to the vehicle body at that time. From the above, in the present invention, the contactor comes into contact with the vehicle body only until the posture of the pallet with respect to the bottom of the vehicle body becomes the mounting posture, and the contactor does not need to be slidably contacted with the vehicle body. The wear of the child can be suppressed, and the replacement cycle of the contact can be made longer than before. Further, according to the present invention, since it is not necessary to provide a guide component on the vehicle body, it is possible to suppress an increase in cost on the vehicle body side by that amount.

As shown in FIGS. 5A and 5B, when an external force acts downward along the vertical direction on the right side of the tilting stage 73 in the vehicle width direction, the tilting stage 73 tilts around the X-axis 728, and the spring mechanism 74, Of the 76, the one on the right side in the vehicle width direction is compressed. Further, as shown in FIGS. 6A and 6B, when an external force acts downward along the vertical direction on the front side of the tilting stage 73 in the front-rear direction of the vehicle body, the tilting stage 73 tilts around the Y-axis 729 and moves forward. The part spring mechanism 74 is compressed.

As shown in FIGS. 2 and 3, two front lock mechanisms 75 are provided on the fixed table 71 on the front side of the front spring mechanism 74 and on the outside along the vehicle width direction.

Further, the rear lock mechanism 77 includes a rod-shaped lock pin 771 extending along the vertical direction and a lock pin drive unit 772 that moves the lock pin 771 forward and backward along the vertical direction in response to a command from a control device (not shown). .. Therefore, as shown in FIGS. 5A, 5B, 6A, and 6B, for example, in a state where the tilt stage 73 is tilted, the tips of the lock pins 751 and 771 are advanced until they come into contact with the lower surface of the tilt stage 73. By fixing the positions of the lock pins 751 and 771, the inclination angle of the inclination stage 73 can be fixed.

FIG. 7 is a flowchart showing a procedure for mounting the battery unit 3 on the vehicle body 9 by the battery unit mounting device 1.

First, in S1, the control device unlocks the inclined stage 73 by the front lock mechanism 75 and the rear lock mechanism 77, and advances the four vehicle body contact pins 525,535,545.555 upward in the vertical direction. Let me.

Next, in S2, the control device raises the elevating arm 62 by the arm drive unit 61, so that the four vehicle body contact pads 526, 536, 546, 556 are supported by the hanger conveyor 2 on the left and right side sills of the vehicle body 9. By raising the pallet 5 and the battery unit 3 mounted on the pallet 5 until all of them come into contact with each other, the postures of the pallet 5 and the battery unit 3 are changed to the mounting postures according to the vehicle body 9 at that time.

When the vehicle body contact pads 526, 536, 546, 556 are pressed against the vehicle body 9 in this way, the vehicle body at that time is moved downward in the vertical direction at the portion of the inclined stage 73 where the support units 52, 53, 54, 55 are provided. A reaction force of a magnitude corresponding to the posture of 9 acts. Therefore, as described with reference to FIGS. 5A and 5B, the pallet 5 and the battery unit 3 are parallel to the bottom 91 of the vehicle body 9 at that time, that is, the postures of the pallet 5 and the battery unit 3 are at that time. The tilting stage 73 is tilted around the X-axis 728 and the Y-axis 729 so as to be in the mounting posture with respect to the vehicle body 9.

Next, in S3, in the control device, the four vehicle body contact pads 526, 536, 546, 556 are in contact with the side sill, and the tilt stage 73 is tilted by the front lock mechanism 75 and the rear lock mechanism 77 in a state where the tilt stage 73 is tilted. Fix the tilt angle of.

Next, in S4, the control device retracts the four vehicle body contact pads 526,536,546,556 from the vehicle body 9 by retracting the four vehicle body contact pins 525,535,545,555 downward in the vertical direction. Let me. Since the inclination angle of the inclination stage 73 is fixed by the front lock mechanism 75 and the rear lock mechanism 77 as described above, even if the four vehicle body contact pads 526, 536, 546, 556 are retracted from the vehicle body 9, the pallet is used. The postures of 5 and the battery unit 3 do not deviate from the mounting posture.

Next, in S5, the control device has two vehicle body alignment pins 528 and 548, respectively, while maintaining the tilt angle of the tilt stage 73 fixed, that is, maintaining the postures of the pallet 5 and the battery unit 3 in the mounting posture. The pallet 5 and the battery unit 3 are raised along the vertical direction by using the elevating device 6 so as to be inserted into the two alignment holes (not shown) formed in the bottom 91 of the vehicle body 9. In a general mounting posture, the vehicle body alignment pins 528, 548 on the pallet 5 side and the alignment holes on the vehicle body 9 side are inclined with respect to the vertical direction. Therefore, in order to insert the vehicle body alignment pins 528 and 548 into the alignment holes, it is necessary to raise the pallet 5 and the battery unit 3 along the extending direction of the vehicle body alignment pins 528 and 548. On the other hand, in the battery unit mounting device 1, the elevating arm 62 of the elevating device 6 floatly supports the pallet 5 via the floating unit 63. Therefore, in S5, by raising the pallet 5 along the vertical direction by using the elevating device 6, the floating unit 63 absorbs the deviation along the horizontal direction, and the vehicle body alignment pins 528 and 548 are aligned holes. Can be inserted into. As a result, the battery unit 3 can be brought close to the bottom 91 of the vehicle body 9 while being aligned. Further, when the vehicle body alignment pins 528 and 548 are pushed all the way into the alignment holes of the vehicle body 9, the plurality of stud bolts 33 provided in the battery unit 3 insert the plurality of holes 93 formed in the vehicle body 9. As a result, the battery unit 3 can be brought close to the bottom 91 in a mounting posture corresponding to the posture of the vehicle body 9 at that time.

Next, in S6, the battery unit 3 is fixed to the bottom 91 of the vehicle body 9 by a fastening robot (not shown). As a result, the battery unit 3 is mounted on the vehicle body 9.

According to the present invention, the following effects are obtained.
In the battery unit mounting device 1, when the pallet 5 is raised by the elevating device 6 on the bottom 91 side of the vehicle body 9, four vehicle body contact pads 526,536,546,556 come into contact with the side sill 92 of the vehicle body 9, whereby the pallet When the posture of the pallet 5 with respect to the vehicle body 9 changes according to the posture of the vehicle body 9 at that time and the posture of the pallet 5 with respect to the vehicle body 9 becomes a predetermined mounting posture, the inclination angle of the inclination stage 73 is fixed by the lock mechanisms 75 and 77. .. Further, in the battery unit mounting device 1, when the inclination angle is fixed by the lock mechanisms 75 and 77, the vehicle body contact pads 526, 536, 546 and 556 can be retracted from the side sill 92. Therefore, in the battery unit mounting device 1, after retracting the vehicle body contact pads 526,536,546,556 from the side sill 92, the pallet 5 is further raised while being maintained in the mounting posture, thereby responding to the vehicle body 9 at that time. The battery unit 3 can be mounted on the vehicle body 9 in the posture. From the above, in the battery unit mounting device 1, the vehicle body contact pads 526,536,546,556 come into contact with the vehicle body 9 only until the posture of the pallet 5 with respect to the bottom 91 of the vehicle body 9 becomes the mounting posture. Further, since it is not necessary to slide the vehicle body contact pads 526,536,546,556 to the vehicle body 9, the wear of these vehicle body contact pads 526,536,546,556 can be suppressed, and by extension, these vehicle body contact pads 526,536,546 , 556 replacement cycles can be longer than before. Further, according to the battery unit mounting device 1, since it is not necessary to provide a guide component on the vehicle body 9, it is possible to suppress an increase in cost on the vehicle body 9 side by that amount.

Although one embodiment of the present invention has been described above, the present invention is not limited to this. Within the scope of the gist of the present invention, the detailed configuration may be changed as appropriate. For example, in the above embodiment, the case where the battery unit 3 is mounted on the vehicle body 9 has been described, but the present invention is not limited to this. The present invention is not limited to the battery unit and can be applied to any work as long as it is mounted from the bottom side of the vehicle body.
