ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an automatic deposition machine, and in particular relates to the technology for depositing members for a protection trimming with high efficiency.
BACKGROUND OF THE INVENTION
For protecting the outside panels of automobile bodies and doors, it has been known to use protection trimming made of band state synthetic resin as an addition to the outside panels of automobile bodies and doors.
FIG.
9
through
FIG. 11
show the conventional examples of a mounting method of such protection trimming. In FIG.
9
through
FIG. 11
, a pair of wire heating elements
9
a
and
9
b
is provided for depositing clip seat
10
and the protection trimming
11
. The bent portion
9
i
is formed on the other end of heating element
9
a
to be described later, and the bent portion
9
j
is formed on the other end side of heating element
9
b
to be described later.
If the terminal
9
c
should be moved in the arrow
9
x
direction, the groove
9
u
of terminal
9
c
is connected to one side of heating element
9
a
, and similarly the groove
9
v
of terminal
9
d
is connected to the other end side of heating element
9
b
. Furthermore, the groove
9
w
of terminal
9
e
is connected to one end side of heating element
9
b
, and the groove (corresponding to the groove
9
v
) of terminal (corresponding to the terminal
9
d
) which is not shown in
FIG. 10
is connected to the other end side of heating element
9
b.
The clip seat
10
has a pair of protrusive faces
10
a
and
10
b
. A great number of pins
10
x
are formed on the protrusive face
10
a
and a great number of pins
10
y
are formed on the protrusive face
10
b
. The protection trimming
11
is in band-state, Numeral
11
a
is the surface of the protection trimming
11
, and Numeral
11
b
is the rear face of the protection trimming
11
. The clip seat
10
and the protection trimming
11
are coupled by the hinge state coupling portion
10
c
, and are molded integral by the synthetic resin.
The heating element
9
a
is arranged such that it may be caught by the pins
10
x
of protrusive face
10
a
, and the heating element
9
b
is arranged such that it may be caught by the pins
10
y
of protrusive face
10
b
.
FIG. 9
shows the status before the heating element
10
b
is arranged.
If the electric current should be provided to the heating elements
9
a
and
9
b
via the terminals (
9
v
, etc.) with the clip seat
10
being bent at the coupling portion
10
c
and the pins
10
x
and
10
y
being contacted to the rear face
11
b
of the protection trimming
11
, the pins
10
x
and
10
y
and the rear face
11
b
of the protection trimming
11
are deposited by the Joule heat of heating elements
9
a
and
9
b.
Thereafter, the heating elements
9
a
and
9
b
are pulled out of the deposited portion using a pair of pliers
12
.
The time needed for each process will be (1) 5 seconds per piece in case of the set of heating elements
9
a
and
9
b
, (2) 2 seconds per piece in case of the bending (integral hinge mono-block molding) of clip seat
10
, (3) 5 seconds per sheet in case of work pieces (clip seat
10
and the protection trimming
11
) set to the machine, (4) 2 seconds in (a) work piece locking, 1 second in the descent of (b) terminals (
9
v
, etc.) and clip seat pressurizing unit, 10 second in (c) voltage impression (heat generation and deposition), 16 seconds in the machine cycle, 1 second in the ascent of (d) terminals (
9
v
, etc.) and clip seat the pressurizing unit and 2 seconds in (e) the work piece lock release in case of the machine operation, (5) 5 seconds per sheet in taking out the work piece and (6) 5 seconds per sheet in pulling out the heating elements
9
a
and
9
b
using a pair of pliers.
Furthermore the necessary work time (e.g., worker time) are as follows as shown in Table 1:

However, in the above described conventional example, the deposition process between the clip seat
10
and the protection trimming
11
is complex and the efficiency of deposition work proved to be inferior.
SUMMARY AND OBJECTS OF THE INVENTION
The present invention has been contrived in view of these problematic points, and its object is to present the automatic deposition machine that can automatically conduct the position between the clip seat and the protection trimming.
The present invention attains this goal by providing an automatic deposition or connection machine with a wire state or shaped heating element. A first connection member is connected to one end of the heating element. A movement means moves the first connection member. A second connection member is connectable to another end side of the heating element. A bending jig overlaps a clip seat of a member of the protection trimming. The clip seat and the protection trimming are interconnected, at a rear face of the protection trimming, via the heating element. A retainer member retains the overlapped clip seat, and a power source carries electric current between the first connection member and the second connection member.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.
