  The jig table has a table surface equal to the product surface shape of the interior trim, and includes a positioning guide that can locate the interior trim at an appropriate position, and a plurality of openings are opened. Includes patterns. The illumination mechanism includes an illumination light disposed on the inner surface side of the opening corresponding to the opening, and a cable that connects the illumination light and a power source (a power supply circuit in the control device). .

  Further, the control device has a plurality of operation buttons set on the operation panel, and can arbitrarily drive the plurality of operation buttons to drive the illumination mechanism having a predetermined pattern. That is, it is possible to illuminate along different pasting patterns by illuminating a part of the illumination mechanism and illuminating the remaining ones. In this case, the light-up timing of the illumination light can be arbitrarily set. Further, the illumination light may be always turned on.

  According to the buffer pad application method and apparatus according to the present invention, after the interior trim using the light-transmitting material is positioned at a predetermined position on the jig table, the illumination corresponding to the predetermined application pattern is provided. The light from the work light passes through the interior trim through the opening of the jig table. Therefore, the point where the buffer pad should be affixed to the back side of the interior trim is lit up, so that the operator can easily and quickly visually check the affixing position of the buffer pad, and the buffer pad affixing operation can be completed quickly. Can do.

  Next, in another embodiment of the method of the present invention, there is provided a buffer pad affixing method in which a buffer pad is affixed to a plurality of locations along a predetermined pattern on an interior trim set on the jig table. A buffer pad attaching device having an opening corresponding to the position and a buffer pad holding mechanism that penetrates into the opening is used, and the interior trim is placed with the back surface of the interior trim facing upward. After setting at a predetermined position on the jig table, the buffer pad holding mechanism is driven by a command from the control device, the block is inserted into the corresponding opening, and the needle provided on the block front end surface penetrates the interior trim. By appearing on the back side of the interior trim, the needle is used as a guide, and a buffer pad is pierced and held by the needle.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best mode of a buffer pad attaching method and an attaching device according to the present invention will be described in detail with reference to the accompanying drawings.

  FIGS. 1 to 4 show a first embodiment of the present invention. FIG. 1 is an explanatory view showing the overall configuration of the buffer pad pasting device according to the present invention. FIG. 2 is a plan view of the pasting device. FIG. 4 is an explanatory view showing the buffer pad attaching method according to the present invention. This first embodiment relates to a buffer pad 5 sticking method and sticking device for sticking a buffer pad 5 having a spacer function and an impact absorbing function to the back surface of a roof trim 1 attached to the interior side of a roof panel of a vehicle body. Apply.

  1 and 2, the buffer pad pasting device 10 according to the first embodiment follows a jig table 20 for setting the roof trim 1, a control device 30 built in the jig table 20, and a predetermined pattern. This is mainly composed of an illumination mechanism 40 that illuminates the buffer pad attaching position P.

  More specifically, the jig table 20 is provided with a table surface substantially equal to the product surface shape of the roof trim 1 for setting the roof trim 1, and an opening 21 is opened at a position corresponding to the attachment position of the buffer pad 5. Has been. The jig table 20 is provided with positioning guides 22 so that the roof trim 1 can be properly located at a predetermined position. The four corners of the jig table 20 are supported by the leg parts 23, and the leg parts 23. A caster 24 is attached to the lower part of the machine so that the work place can be changed. A control device 30 is mounted on the bottom plate 25.

  The control device 30 operates the plurality of operation buttons 32a, 32b, and 32c on the operation panel 31, thereby operating the control device 30 and selectively driving the illumination mechanism 40. The illumination mechanism 40 includes an illumination light 41 attached to the inner surface side of the opening 21 provided in the jig table 20 corresponding to the opening 21, and a power supply circuit for the illumination light 41 and the control device 30. The illumination light 41 is fixed to the inner surface of the jig table 20 via a bracket 43. In the present embodiment, as shown in FIG. 2, illumination mechanisms 40a to 40j are provided corresponding to the ten openings 21a to 21j, respectively.

  Next, an operation procedure for attaching the buffer pad 5 to the roof trim 1 will be described with reference to FIGS. First, the base material 2 in the roof trim 1 is set on the jig table 20 facing upward. At this time, since it is necessary to transmit light to the back side of the roof trim 1, a material having light transmittance is used as the material of the roof trim 1. Then, after locating the roof trim 1 accurately using the positioning guide 22 as a guide, if the operation button 32a of the operation panel 31 is operated, the six illumination mechanisms 40a, 40b, 40d, 40g, 40i, and 40j along the A pattern are operated. Drive. Then, the six illumination mechanisms 40 are lit up, and through the corresponding openings 21a, 21b, 21d, 21g, 21i, and 21j, the back surface of the roof trim 1 set on the jig table 20 as shown in FIG. Six buffer pad pasting positions P1 to P6 are lit up on the side.

  Accordingly, if the buffer pad 5 to which the hot melt adhesive 6 is applied in advance is pasted on the back surface of the roof trim 1 for the six buffer pad pasting positions P (P1 to P6) lit up by the illumination mechanism 40, The buffer pad 5 can be easily and quickly pasted. Further, since the area of the buffer pad attaching position P is determined according to the vertical and horizontal dimensions of the opening 21 in the jig table 20, if the outer dimensions of the buffer pad 5 are matched with the area of the buffer pad attaching position P, The buffer pad 5 urged according to the size of the opening 21 can be attached, and erroneous attachment can be reliably prevented, and the attaching operation of the buffer pad 5 can be performed easily, quickly and reliably.

  Further, in order to change the affixing pattern for affixing the buffer pad 5 to the roof trim 1, for example, when the buffer pad 5 is affixed to 10 positions symmetrical on the back side of the roof trim 1, the operation button 32b of the operation panel 31 is operated. In this case, the controller 30 may be programmed so that all the illumination mechanisms 40a to 40j corresponding to the openings 21a to 21j of the jig table 20 are turned on. In this case, when the back surface 10 of the roof trim 1 is lit up and the buffer pad application position P is lit up, if the buffer pad 5 is applied according to the light up location, the application pattern is changed. However, the attaching operation of the buffer pad 5 can be completed efficiently.

  As described above, in the first embodiment, the opening 21 is opened in the jig table 20, the illumination mechanism 40 is arranged for each opening 21, and the illumination mechanism 40 is selectively lit along a predetermined pattern. By illuminating the buffer pad application position P, the application of the buffer pad 5 can be completed easily, and there is no need to process the marking on the back surface of the roof trim 1 as in the prior art. There is also an attendant advantage that man-hours can be eliminated.

  In the above-described embodiment, the buffer pad pasting position P is lit up by operating the operation buttons 32a, 32b, and 32c. However, the timing of the lit-up is arbitrary, for example, before the roof trim 1 is set. Can be set. Further, the illumination light 41 may be always turned on.

  FIG. 5 to FIG. 10 show the second embodiment, FIG. 5 is an explanatory view showing the overall configuration of the buffer pad sticking device, FIG. 6 is a plan view showing a jig table of the sticking device, and FIG. FIG. 8 to FIG. 10 are explanatory views showing a second embodiment of the buffer pad attaching method.

  The second embodiment also applies to a structure in which the buffer pad 5 having a spacer function is attached to the back surface of the roof trim 1, but the roof trim 1 used in the second embodiment does not necessarily have light transmittance. Instead, it is necessary to use a soft material through which the needle penetrates.

  5 to 7, the buffer pad pasting device 100 in the second embodiment uses the jig table 20 and the control device 30 that are substantially the same as the pasting device 10 described in the first embodiment. Specific configurations of the table 20 and the control device 30 are omitted. In the second embodiment, the buffer pad holding mechanism 50 is provided in place of the illumination mechanism 40, which is a structural feature.

  That is, the buffer pad holding mechanism 50 is provided on the block 51 that moves forward and backward so as to enter the opening 21 of the jig table 20, the cylinder 52 that moves the block 51 forward and backward, and the tip surface 51 a of the block 51. A needle 53 that pierces and holds the pad 5 is generally configured. As shown in FIG. 7, positioning needles 54 that serve as a guide for determining the external dimensions of the buffer pad 5 are provided at the four corners on the front end surface 51 a of the block 51. The size of the buffer pad 5 is determined by the interval of 54 (indicated by symbols a and b in the figure). The cylinder 52 in the buffer pad holding mechanism 50 is supported on the bottom plate 25 via a support member 55.

  Also in the second embodiment, as shown in FIG. 6, ten openings 21 a to 21 j are opened in the jig table 20, and the buffer pad holding mechanism 50 a to 50 a corresponding to each opening 21 a to 21 j. 50j is provided. Then, by arbitrarily operating the various operation buttons 32a to 32c of the operation panel 31 of the control device 30, an appropriate selection can be made from among the buffer pad holding mechanisms 50a to 50j. .

  Next, the work procedure in the second embodiment of the attaching operation of the buffer pad 5 will be described with reference to FIG. 8. First, the roof trim 1 is set at a predetermined position on the jig table 20 using the positioning guide 22 as a guide. . Next, by operating any of the operation buttons 32 a to 32 c of the operation panel 31, the cylinder 52 in the buffer pad holding mechanism 50 is extended by a command from the control device 30, and the block 51 enters the opening 21. Since the needle 53 and the positioning needle 54 provided on the front end surface 51 a of the block 51 pass through the roof trim 1 and protrude from the back surface of the base member 2, the operator can use the needle 53, penetrating the roof trim 1, 54 is visible. Therefore, the buffer pad 5 to which the hot melt adhesive 6 has been applied in advance is pierced into the needle 53, so that the buffer pad 5 can be easily attached to the back surface of the roof trim 1. At this time, since the buffer pad 5 having a size determined by the positioning needle 54 may be selected, erroneous attachment of the buffer pad 5 can be reliably prevented.

  Then, as shown in FIG. 9, the buffer pad 5 is pasted to the buffer pad pasting position P along the predetermined pattern of the roof trim 1 via the hot melt adhesive 6. At this time, the buffer pad 5 is attached to the needle 53. Thus, the hot melt adhesive 6 is supported until it is solidified, so that even if the buffer pad application position P is an inclined portion, a precise operation can be performed without causing positional displacement.

  Next, when the application of the buffer pad 5 is completed, as shown in FIG. 10, the cylinder 52 in the buffer pad holding mechanism 50 is contracted to retract the block 51, and the needle 53 and the positioning needle 54 are moved to the buffer pad. 5 and the roof trim 1. Thereafter, the roof trim 1 may be taken out from the jig table 20.

  Therefore, the second embodiment has the same effect as the first embodiment that it is possible to reliably prevent erroneous attachment in the attaching operation of the buffer pad 5 and to obtain quick attaching workability, and in particular, the buffer pad holding mechanism. 50, since the buffer pad 5 is pierced and held by the needle 53, for example, even if the attachment position of the roof trim 1 is an inclined portion, the buffer pad 5 can be held at the attachment position by the needle 53. There is an effect that the positional deviation can be surely prevented and the degree of freedom of modeling at the pasting position can be freely selected.

  In the first embodiment, the opening 21 in the jig table 20 needs to be strictly managed in the vertical and horizontal dimensions. However, in the second embodiment, the block 21 in the buffer pad holding mechanism 50 enters the opening 21. Since it is only necessary to allow this, the dimension setting of the opening 21 and the opening work can be performed relatively roughly, so that the processing work of the jig table 20 can be simplified.

  The first and second embodiments described above are specific examples in which the buffer pad 5 is attached to the back surface of the roof trim 1, but in addition to the roof trim 1, it is applied to interior trims such as a dash side trim and a luggage side trim. If the jig table has a light-up mechanism, it can be applied to all other parts such as brackets in place of the buffer pad 5 used in the first and second embodiments. be able to.
