Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection device used when inspecting a wire harness after completion of assembly. More specifically, the present invention relates to an inspection device for inspecting whether or not there is any defect in the mounting of exterior parts in the appearance inspection process of a wire harness.

[0002]

2. Description of the Related Art For example, in a wire harness for an automobile, generally, a large number of scaled electric wires cut into predetermined dimensions are
They are bundled so as to have a predetermined wiring form. In many cases, what is called an exterior part such as a clamp or a grommet is attached to the bundled electric wires.

These exterior parts must be accurately attached to a predetermined position of an electric wire (usually a bundle of electric wires in which a predetermined number of electric wires are bundled). This is because if the type of clamp that is attached is incorrect or if the attachment position is displaced from the specified position, the position of the clamp attached to the wire bundle and the formation on the vehicle body when the wire harness is assembled to the vehicle body. The position of the clamp mounting hole will not match. As a result, the wire harness cannot be fixed to the vehicle body.

For this reason, conventionally, at the final stage of the production of the wire harness, a so-called visual inspection is performed to inspect whether or not the correct type of exterior component is correctly attached to a predetermined position. This appearance inspection is performed using an exterior component attachment inspection device. The outline of the appearance inspection procedure is as follows. First, support the assembled wire harness on the inspection drawing board using a predetermined support tool, and deploy the wiring so that it has the same form as when actually assembled on the vehicle body. . Further, the exterior component attachment inspection device is installed in advance at a predetermined position on the inspection drawing board. The predetermined position is a position at which the exterior component should be accurately attached in a state where the wire harness to be inspected is laid out on the inspection drawing board.

That is, if the exterior parts are correctly attached, when the wire harness is laid out on the inspection drawing board, the position of the attached exterior parts and the position of the exterior part attachment inspection device match. . This makes it possible to detect and confirm that the exterior component is correctly attached. The exterior component attachment inspector corresponds to the type of the exterior component to be inspected, and if the type of the exterior component to be inspected is different, the exterior component attachment inspector having different specifications is used.

[0006] The mounting inspection of the fitting type clamp in the visual inspection will be specifically described below by taking a specific exterior part, for example, the fitting type clamp as an example. 8 and 9 are external perspective views of the insertable clamp (hereinafter, simply referred to as “clamp”) 1. FIG. 8 shows an open state before attachment to the wire bundle E, and FIG. The state after attaching to the electric wire bundle E is shown. First, the clamp 1 will be described with reference to these drawings. Clamp 1 is electric wire E
It is a type that is attached to an electric wire by fitting it on.

The clamp 1 has a base 2 and an engaging piece 3 rotatably attached to the base 2, and the engaging piece 3 is rotated in the direction of the white arrow to engage with the base 2. By fitting them together, as shown in FIG. 9, a fitting space 4 in which the electric wire bundle E can be held is formed. A locking claw 32 is formed on the tip portion 31 of the engagement piece 3.
A recess 21 into which the tip 31 of the engagement piece 3 can be inserted is formed below the base 2. Although not shown, the locking claw 32 is provided inside the recess 21.
A tongue is formed that can engage with. Therefore, the wire bundle E
Is arranged between the base portion 2 and the engaging piece 3, and the distal end portion 31 of the engaging piece 3 is inserted into the recess 21 of the base portion 2 to engage the locking claw 32 with the tongue piece. The clamp 1 can be fixed to the electric wire bundle E in a state where the bundle E is held in the fitting space 4 (state of FIG. 9).

Next, FIG. 10 is a perspective view of essential parts showing a state in which an attachment inspection of the clamp 1 is performed using a conventional clamp exterior component attachment inspection device (hereinafter referred to as "inspection device") 5. Is. With reference to FIG. 10, the inspection device 5 is arranged on an inspection drawing board 6. On the other hand, the wire harness including the clamp 1 (the wire harness that is the target of the inspection) is laid out on the inspection drawing board 6. As shown in the figure, the inspection device 5 is fastened and fixed to the inspection drawing plate 6 with a nut N, and the head portion (inspection device main body) 7 for detecting the clamp 1 has a predetermined shape on the inspection drawing plate 6. It is located in a position. The predetermined position is a position corresponding to the regular mounting position of the clamp 1 mounted on the wire harness in which the wiring is expanded.

The head portion 7 has a housing chamber 71 capable of housing the clamp 1. That is, the inner surface shape of the accommodation chamber 71 is formed so as to match the outer diameter shape of the clamp 1, and it can be said that the clamp 1 and the accommodation chamber 71 are in a so-called substantially male-female relationship. Further, as shown in FIG. 10, a recess 11 is usually formed on the back surface 12 of the clamp 1. The recess 11 is formed for attaching the clamp 1 attached to the electric wire to a predetermined portion. The head portion 7 is formed with a protruding rod 72 that protrudes into the accommodation chamber 71. The protruding rod 72 can be inserted into the recess 11 and can be fitted tightly. Further, the head portion 7 is provided with a clamp detection sensor 73. When the clamp 1 is housed in the housing chamber 71, the clamp detection sensor 73 can detect the clamp 1.

The mounting inspection of the clamp 1 is performed as follows. Assuming that the clamp 1 is correctly attached to the wire bundle E of the wire harness that has been developed, the clamp 1 can be accommodated in the accommodation chamber 71 when the wiring is developed. This is because the head portion 7 is arranged at the regular mounting position of the clamp 1 in a state where the wire harness has been deployed in advance. Further, if the clamp 1 is correctly attached, the protruding rod 72 on the inspection device 5 side is inserted and engaged in the recess 11 of the clamp 1, and the clamp 1 is
It is surely accommodated in the accommodation chamber 71. As a result, the clamp detection sensor 73 operates. Here, since the accommodation chamber 71 corresponds to the shape of the clamp 1, even if an attempt is made to accommodate a clamp other than the clamp 1, the outer shape of the clamp does not match the inner surface shape of the accommodation chamber 71, or
Due to the interference of the protruding rod 73, it cannot be accommodated in the accommodation chamber 71. That is, if the clamp detection sensor 73 operates, it can be confirmed that the clamp 1 of the determined type is attached at the correct position.

[0011]

By the way, depending on the specifications of the wire harness, the mounting direction of the clamp 1 may be determined to be a predetermined direction. In FIG. 10, the clamp 1 is attached with the back surface 12 along the vertical direction. That is, the recess 11 of the clamp 1 extends in the horizontal direction. For this reason, the head portion 7 of the inspection device 5 is arranged so that the protruding rod 72 is along the horizontal direction. When the clamp 1 is mounted in such a mounting direction, there have conventionally been the following problems.

Referring to FIG. 11, this figure shows a state in which the clamp 1 is housed in the housing chamber 71 of the inspection device 5. Since the head portion 7 of the inspection device 5 is arranged so that the protruding rod 72 extends along the horizontal direction, the clamp 1 is fitted from the side. The head portion 7 can exactly accommodate the clamp 1 in the accommodation chamber 71, but does not have a function for holding the accommodated clamp 1.

Therefore, the clamp 1 tends to come off even if it is once held. Therefore, there is a problem in that the clamp 1 is separated from the clamp detection sensor 73, and the clamp detection sensor 73 does not operate even though the determined clamp 1 is accurately attached to the correct position. This problem may occur regardless of the mounting direction of the clamp 1 as long as the head portion 7 does not have the holding function of the clamp 1. That is, even if the clamp 1 is fitted from above, the clamp 1 may be separated (lifted) from the clamp detection sensor 73.

In some cases, the clamp 1 is disengaged from the head portion 7 and the inspection itself cannot be carried out smoothly. Therefore, an object of the present invention is to provide a mounting inspection device for a mounting clamp, which can surely perform a mounting inspection of a mounting clamp regardless of a mounting direction, and can smoothly advance a visual inspection of a wire harness. Is to provide.

[0015]

In order to achieve the object of the present invention, a mounting inspection device for a fitting type clamp according to claim 1 is provided.
A fitting-type clamp that has a base portion and an engagement piece that engages with the base portion, can be attached to the electric wire bundle by hugging the electric wire bundle with both, and has a mounting recess at a predetermined position. Is a mounting inspection device for a fitting type clamp for performing a mounting inspection of the fitting type clamp at the time of visual inspection of a wire harness, the fixing part capable of being fixed to an inspection drawing board, and the fixing part. And an inspector body capable of holding an insertable clamp as an inspected object in a state of being sandwiched between the inspector body and the inspector main body, the inspector main body being capable of abutting on one portion of the insertable clamp. And a first sandwiching surface portion that is disposed so as to face the first sandwiching surface portion, and can contact another portion of the insertable clamp in a state where the first sandwiching surface portion abuts one portion of the insertable clamp. By bringing the two clamping surface parts close to each other A proximity position for restricting the entry of the fitting clamp to between 1 and the second clamping surface, the first and second by away from each other from the proximity position
The first and second clamping surface portions are always close to each other, and the contacting / separating mechanism that relatively displaces the clamping surface portions relative to each other between the separating and disposing position that allows the insertion-type clamp to enter between the clamping surface portions. An urging member for urging the insertable clamp so as to be in the arrangement position, and a pinching permitting means for allowing the pinchable clamp to be pinched by the first and second pinching surface portions when the pinchable clamp has a predetermined outer shape. It is characterized by having.

According to this structure, the following effects are achieved. First, the fitting clamp attachment inspection device is fixedly arranged at a predetermined position on the inspection drawing board. On the inspection drawing board, the assembled wire harness is received by a required support tool and the wiring is developed. At this time, if the insertable clamp is not attached to the assembled wire harness at the correct position, the position of the insertable clamp and the inspection device body is displaced.

When the insertable clamp is mounted at the correct position of the assembled wire harness, the position of the insertable clamp and the position of the main body of the inspection device match. Next, the contacting / separating mechanism separates the first holding surface portion and the second holding surface portion from each other at the separated arrangement position, and the fitting clamp is inserted between the both holding surface portions. Since both clamping surface portions are always urged by the urging member so as to be in the close arrangement position, the first and second clamping surface portions are in a state of sandwiching the insertable clamp. At this time, by the pinching allowance means,
Only when the insertable clamp has a predetermined outer shape, the insertable clamp can be sandwiched between the sandwiching surface portions.

In order to achieve the object of the present invention, a mounting clamp attachment inspection device according to a second aspect is the attachment clamp attachment inspection device according to the first aspect, wherein the first clamping surface portion or the second clamping surface portion is used. At least one of the sandwiching surface portions is formed so as to have a shape along the corresponding one portion or the other portion of the insertable clamp, and the sandwiching allowance means includes the first sandwiching surface portion and The second clamp surface portion and the insertable clamp enter between the two clamp surface portions, and the first clamp surface portion or the second clamp surface portion is fitted along one portion or the other portion of the corresponding snap clamp portion. It is characterized in that it has a projecting portion that can be fitted in the mounting recess of the fitting type clamp in the state of being in contact.

According to this structure, the same operation as that of the invention according to claim 1 is achieved. In particular, in the claimed invention,
When the insertable clamp is sandwiched by the first and second sandwiching surface portions, the first sandwiching surface portion or the second sandwiching surface portion follows the shape of one portion or the other portion of the corresponding insertable clamp. Only when they come into contact with each other, the protruding portion fits into the mounting recess of the insertable clamp. Then, only when this state is reached, the insertable clamp can be clamped by the two clamping surface portions.

That is, it is possible to hold the wire harness by the main body of the inspection device only when the insertable clamp having the predetermined shape is attached at the correct position of the assembled wire harness. In this holding, the protruding portion is fitted into the mounting recess of the fitting type clamp to position the fitting type clamp, and then the first holding surface portion or the second holding surface portion is provided.
It is achieved by abutting at least one of the sandwiching surface portions of the above-mentioned clamping surfaces along the shape of one portion or the other portion of the corresponding snap-in clamp.

Therefore, even if the insertable clamp is inserted between the two holding surface parts, the insertable clamp cannot be held between the two holding surface parts unless the mounting recess and the protruding part are fitted together. Can't hold. Further, even if the mounting recess and the protrusion are fitted to each other, at least one of the first holding surface portion and the second holding surface portion corresponds to one portion or another portion of the fitting type clamp. The contact-type clamp cannot be clamped unless it abuts along the shape of, and as a result, the lock-in clamp cannot be held.

In order to achieve the object of the present invention, a mounting clamp attachment inspection device according to a third aspect of the present invention is provided with the first aspect or the second aspect.
In the fitting type clamp attachment inspection device described above, the inspection device main body is provided so as to be rotatable with respect to a base and a first rotation axis, and the both sandwiching surface portions are arranged apart from each other. A first clamp arm that can be rotated about the first rotation axis by abutting and pressing the insertable clamp to be inspected to bring it to the position, and opposite the first clamp arm. A second pinching arm that is arranged so as to be rotatable with respect to the base about the second pivotal axis, and that the first pinching arm has a second pivotal axis that is greater than that of the first pivoting axis. The first sandwiching surface portion is configured by the predetermined portion on one side, and the second sandwiching surface portion is configured by the predetermined portion on one side of the second rotating shaft of the second sandwiching arm. The contacting / separating mechanism includes an end portion of the first holding arm on the other side of the first rotation shaft and a first holding arm. Of the holding arm is connected to the end portion on the other side of the second rotation shaft so as to be relatively rotatable, and the second holding arm is rotated in conjunction with the rotated first holding arm. It is characterized in that it includes a connecting portion.

According to this structure, the same operation as that of the invention according to claim 1 or 2 is achieved. Particularly, in the invention according to the present claim, when the first clamp arm is rotated by pressing the insertable clamp against the first clamp arm, the second clamp arm connected via the connecting portion moves to the first clamp arm. It rotates in conjunction with the holding arm of. That is, the first and second sandwiching surface portions are separated from each other and are arranged at the separated arrangement position. In this state, the retractable clamp is advanced between the first and second clamping arms.

At this time, if the insertable clamp to be inspected has a predetermined shape, the mounting recess of the insertable clamp and the above-mentioned protrusion are fitted together, and the first holding surface portion or The second holding surface portions abut along the shape of one portion or the other portion of the corresponding snap-in clamp. Accordingly, the insertable clamp can be sandwiched and held between the first and second sandwiching surface portions.

On the other hand, if the insertable clamp to be inspected is not of a predetermined shape, the insertable clamp is pressed against the first clamping arm to separate the first and second clamping surface portions. Even if it is arranged at the arrangement position and the fitting type clamp is inserted between both the sandwiching surface portions, the mounting recess and the protrusion cannot be fitted. This is because the insertable clamp to be inspected does not have a predetermined shape, and the positions of the protrusion and the mounting recess do not match. Therefore, the insertable clamp cannot be held between the first and second holding surface portions.

In order to achieve the object of the present invention, a fitting type clamp attachment inspection device according to a fourth aspect is the insertion type clamp attachment inspection device according to the third aspect, wherein the first holding surface portion is the above-mentioned. The protrusion is formed in a shape that follows one portion of the insertable clamp, and the protrusion presses the insertable clamp against the first clamping arm to dispose the first and second clamping surface portions at the separated arrangement position. The first part of the insertable clamp is the above
Of the insertable clamp, which is in contact with the sandwiching surface of the second clamp arm, is provided so as to project from a position where the insertable clamp is fitted into the mounting recess, and prevents the insertable clamp from contacting the second sandwiching arm. The contact regulating member is provided.

According to this structure, the same operation as that of the invention according to claim 3 is achieved. In particular, in the claimed invention,
The insertable clamp is pressed against the first sandwiching arm so that both sandwiching surface portions are arranged at the separated positions, and the insertable clamp is set in this state. In addition, the abutting restricting member prevents the fit-in type clamp from abutting against the second holding surface portion of the second holding arm. That is, it is not possible to attempt to dispose the first sandwiching surface portion and the second sandwiching surface portion in the separated arrangement position and to bring the insertable clamp into contact with the second sandwiching arm. Therefore, by pressing the second holding arm, the first and second holding surface portions are arranged in the separated arrangement position, and in this state, the protrusion and the mounting concave portion are fitted to each other. I can't.

The state in which the two are placed is defined as the separated arrangement position of both 311 and 411.

Referring to FIGS. 3 and 4, in this embodiment, a coil spring is used as the urging member 800. The biasing member 800 is interposed between the first L-shaped member 300 and the contact plate 120. Specifically, the urging member 800 has one end side of the connecting portion 32 of the first L-shaped member 300.
0 is fitted into a seat portion (not shown) provided,
The other end side is in contact with the back surface of the backing plate 120. In addition,
The seat portion is provided near the connecting portion 510.

By the biasing member 800, the connecting portions 320 and 420 of the first and second L-shaped members 300 and 400 are connected.
4 is pressed to the left side in FIG. 4, whereby the curved surface 311 on the side of the first L-shaped member 300 and the second L
The upper surfaces 412 on the shaping member side are urged in directions relatively approaching each other. That is, the curved surface 311 and the upper surface 412 are constantly biased so as to be displaced toward the adjacent arrangement position side, whereby the clamp 1 is elastically elasticized by the first L-shaped member 300 and the second L-shaped member 400. It can be clamped. At this time,
The curved surface 311 constitutes a first sandwiching surface portion, and the upper surface 412 constitutes a second sandwiching surface portion. A torsion coil spring may be used instead of the coil spring. That is, this torsion coil spring is
10 and the first L-shaped member 300 and between the base 110 and the second L-shaped member 400, the rotation pins 301, 401.
It can also be attached concentrically with.

Referring to FIG. 3, the projecting rod 600 has a prismatic shape and can be fitted exactly into the recess 11 (see FIG. 1) of the clamp 1. The protruding bar 600 is provided so as to protrude toward the lower part of the center of the contact plate 120. Specifically, the protruding bar 600 is provided with the concave portion 11 of the clamp 1 when the clamp 1 enters between the first L-shaped member 300 and the second L-shaped member 400 and is clamped by the curved surface 311 and the upper surface 412. It is placed in a position that fits snugly in.

More specifically, assuming that the clamp 1 is accurately mounted at a predetermined position of the wire harness as the inspection object, the clamp 1 is inserted between the L-shaped members 300 and 400. When the protruding bar 600 enters the recess 11, the clamp 1
The protruding bar 600 is arranged at a position where it is sandwiched by the curved surface 311 and the upper surface 412.

Therefore, at the time of inspection, the clamp 1
Both L-shaped members 3 are pressed against the L-shaped member 300.
When it is made to enter between 00 and 400, the curved surface 311 slides on the upper surface portion of the clamp 1 and the protruding rod 60
0 is inserted into the recess 11. Then, the curved surface 311
The projecting rod 600 fits completely into the recess 11 when the is closely abutted along the upper surface portion of the clamp 1. As a result, the clamp 1 is held by being sandwiched between the curved surface 311 and the upper surface 412 by the elastic force of the contact urging member 800 while being positioned on the protruding rod 600.

By the way, the recess 11 and the protruding bar 6 are simply used.
Even when 00 and 00 are fitted, the clamp 1 cannot be sandwiched between the both surfaces 311 and 412 unless the shape of the upper surface of the clamp to be held corresponds to the shape of the curved surface 311. This is because clamps that do not correspond to the curved shape of the curved surface 311 are attached to both surfaces 311 and 412.
This is because, even if the clamp 1 is inserted between them, the clamp 1 cannot be sandwiched and held between the both surfaces 311 and 412, and the clamp 1 comes off.

That is, the curved shape of the curved surface 311 and the position where the protruding bar 600 is provided as a protrusion are necessary elements for sandwiching and securely holding the clamp 1. The curved surface 311 and the protruding bar 600 including these necessary elements constitute a means for holding the clamp 1 (holding means). In other words, the curved surface 311 is curved to have a predetermined shape, and the protruding bar 600 is arranged at a predetermined position, so that both L-shaped members 300 and 400 are provided.
A clamp other than the clamp 1 (having different external shape and size) cannot be sandwiched and held between them.

Referring to FIG. 3, a pair of contact regulating rods 71
Reference numerals 0 and 720 are flat plates and are provided on the backing plate 120 so as to project therefrom. These contact restricting rods 710, 720 are provided below the protruding rod 600, and the protruding piece 4 of the second L-shaped member 400.
It is provided on both the left and right sides with 11 in between. Further, the upper surfaces 711 and 721 of the contact regulating rods 710 and 720 are arranged so as to be in a so-called substantially flush state with the upper surface 412 of the projecting piece 411. The protrusion pieces 411 are protected by the arrangement of the contact restriction rods 710 and 720. Regarding the action and effect of the contact regulating rods 710 and 720,
Details will be described later.

(3) Operation / Effect of Inspection Device A Next, how to use the inspection device A when performing the mounting inspection of the clamp 1 will be described together with its operation effects. As shown in FIG. 1, the assembled wire harness is laid out on the inspection drawing board 6. At this time, if the clamp 1 is not mounted at the correct position on the wire harness, the positions of the clamp 1 and the inspection device body 100 are displaced. As a result, it can be clearly seen that the clamp 1 is not correctly mounted at the predetermined position.

When the clamp 1 is mounted at the correct position on the wire harness, the clamp 1 and the inspection device body 1
The position of 00 matches. Then, the first L-shaped member 300 and the second L-shaped member 400 are relatively displaced via the contacting / separating mechanism 500, and the curved surface 311 on the first L-shaped member 300 side and the upper surface 412 on the second L-shaped member 400 side, It is placed at a separation position.

Next, the clamp 1 is inserted between the curved surface 311 and the upper surface 412. Curved surface 311 and upper surface 412
Is always urged by the urging member 800 in a direction in which they approach each other.
It is sandwiched between 12 and. At this time, the above-mentioned holding permitting means can hold only the clamp 1 sandwiched between the curved surface 311 and the upper surface 412 only when the insertable clamp has a predetermined outer shape. it can.

The inspector body 100 is arranged at a position where the clamp 1 is arranged when the wire harness is unfolded, assuming that the clamp 1 is correctly attached to the wire harness. Therefore, if the clamp 1 can be held by being sandwiched between the curved surface 311 and the upper surface 412, the insertable clamp of a predetermined type (shape) can be accurately positioned at a predetermined position. You can see that it is installed.

As described above, whether or not the clamp 1 is correctly attached without any trouble can be easily and surely inspected by checking whether or not the clamp 1 can be sandwiched and held by the inspection device main body 100. . Moreover, since the clamp 1 is sandwiched and held, the clamp 1 may move in the direction in which it disengages from the inspector main body 100 or may disengage during the inspection regardless of the mounting direction of the clamp 1. There is nothing to do.

As a result, the following effects are obtained. During the above-mentioned inspection, not only the clamp 1 is inspected but also other clamps and exterior parts such as grommets are inspected at the same time. Therefore, when the clamp 1 moves in the direction of coming off the inspector main body 100, or when the clamp 1 comes off and straddles, it is necessary to carry out a repair work to restore it, but during this repair work, other exterior parts There is a case where it comes off, and it is necessary to further correct this. On the other hand, in the present embodiment, such inconvenience does not occur, and it is not necessary to perform correction work or the like due to the clamp 1 coming off the inspector body 100 during the inspection, and the inspection work can be performed smoothly. You can proceed.

In this embodiment, the inspection is specifically carried out according to the following inspection procedure. Hereinafter, a specific inspection procedure will be described together with its function and effect. With reference to FIG. 4, the curved surface 311 and the upper surface 41.
When the clamp 1 is sandwiched by the clamp 2, the clamp 1 is held by hand, and the curved upper surface portion of the clamp 1 (the upper surface portion of the base portion 2 and the upper surface portion of the engaging piece 3 continuous with the base portion 2) is moved to the first L
The clamp 1 is moved to the left side in the drawing while being pressed against the tip of the holding arm 310 of the shaped member 300 (see FIG. 5). By pressing the clamp 1 against the tip of the holding arm 310, the tip rotates in the direction of the white arrow. As a result, the first and second L-shaped members 300 and 400 are relatively displaced through the connecting portion 510 of the contacting / separating mechanism 500, and the curved surface 311 and the upper surface 412 are arranged at the separated arrangement position.

Then, by moving the clamp 1 to the left side in the figure as it is, as shown in FIG.
Are inserted between the curved surface 311 and the upper surface 412. At this time, if the concave portion 11 of the clamp 1 and the protruding bar 600 are fitted and the curved surface 311 abuts along the upper surface portion of the clamp 1, the clamp 1 is sandwiched between the curved surface 311 and the upper surface 412. Can be held at. as a result,
It can be seen that the insertable clamp of the predetermined type (shape) is accurately mounted at the predetermined position.

On the other hand, when the clamp 1 is inserted between the curved surface 311 and the upper surface 412, the concave portion 1 of the clamp 1
If the 1 and the protruding bar 600 cannot be fitted, the clamp 1 cannot be sandwiched between the curved surface 311 and the upper surface 412. For example, if the external shape of the clamp to be inspected is similar to the clamp 1, the curved surface 311
Can contact the clamp, but the position of the protruding bar 600 does not match the position of the recess of the clamp, and the protruding bar 600
Cannot be fitted in the recess. As a result, the clamp 1 cannot be sandwiched between the curved surface 311 and the upper surface 412, and the clamp to be inspected has a shape and size different from those of the insertable clamp of a predetermined type. I understand.

As described above, in this embodiment, the curved surface 311 is formed.
The protruding bar 60 is not inserted into the concave portion 11 of the clamp 1 only when the contact portion of the clamp 1 is brought into close contact with the upper surface of the clamp 1.
0 is fitted. Then, only when this state is reached, the clamp 1 can be sandwiched between the curved surface 311 and the upper surface 412. Ie the right type of clamp 1
The curved surface 311 to detect that the
A simple structure is adopted in which the shape of (1) corresponds to the shape of the upper surface portion of the clamp 1, and the protruding bar 600 is provided so as to be fitted into the recess 11 of the clamp 1.
Thereby, there is an advantage that the inspection device A can be provided at low cost.

Further, in the present embodiment, as shown in FIGS. 4 to 6, when the clamp 1 is sandwiched by the curved surface 311 and the upper surface 412, the clamp 1 is pushed to the left side in FIG. be able to.
Thereby, there is an advantage that the attachment inspection of the clamp 1 can be carried out more smoothly. In the present embodiment, the upper surface 412 is formed as the second holding surface portion on the second L-shaped member 400 side. The upper surface 412 only contacts the lower surface of the clamp 1, but the area of the upper surface 412 may be further increased so that the upper surface 412 can exactly contact the lower surface of the clamp 1. . By forming the upper surface 412 in this way, the clamp 1 can be sandwiched and held by the curved surface 311 and the upper surface 412.

The curved surface 311 and the upper surface 412 are also provided.
Are respectively holding arms 310 of the first L-shaped member 300.
Also, the curved surface 311 and the upper surface 412 are made to come into contact with and separate from each other by rotating the members 300 and 400 by forming a predetermined portion near the tip of the holding arm 410 of the second L-shaped member 400. Curved surface 3 using a member
11 and the upper surface 412 is separately configured by using a flat plate member, and the curved plate 311 and the upper surface 41 are arranged by directly disposing the curved plate member and the flat plate member so as to face each other.
It is also possible to bring the two into contact with and separate from each other.

In addition, the contact regulating rods 710 and 720 allow the clamp 1 to move the second L-shaped member 400 during the inspection.
Side upper surface 412 does not come into contact. Explaining in detail with reference to FIG. 3, if the contact regulating rods 710 and 720 are not provided, when the clamp 1 is inserted between the first L-shaped member 300 and the second L-shaped member 400, the clamp 1 is erroneously inserted.
May be brought into contact with the protruding piece 411 of the second L-shaped member 400. Thereby, the first and second L-shaped members 30
The 0 and 400 rotate, and as a result, the curved surface 311 and the upper surface 412 are displaced to the separated arrangement position, and the clamp 1 is ready to enter between the curved surface 311 and the upper surface 412. In some cases (for example, when a clamp having a shape similar to the clamp 1 and smaller than the clamp 1 is mounted), the clamp is sandwiched and held between the protruding bar 600 and the upper surface 412. There is a risk of being destroyed. In other words, despite the fact that a clamp of a size different from the clamp 1 of a predetermined size is mounted,
There is an inconvenience that the inspection may pass.

However, in the present embodiment, the contact regulating rod 7
As described above, that is, 10, 720 are arranged on both sides of the projecting piece 411 of the second L-shaped member 400, and the upper surfaces 711, 721 of the contact restricting rods 710, 720 are the upper surfaces 412 of the projecting piece 411. Are arranged so that they are substantially flush with each other. That is, the projecting piece 411 has the contact regulating rods 710, 720.
Are guarded by. Therefore, even when the clamp 1 is inserted between the curved surface 311 and the upper surface 412, the clamp 1 does not come into contact with the upper surface 412, and the first
The clamp 1 is brought into contact with the L-shaped member 300.
Therefore, the above inconvenience can be avoided.

(4) Design Modification Example The present invention is not limited to the above embodiment, and various design modifications such as the following can be made. In the above-described embodiment, whether or not the mounting inspection of the clamp 1 is successful can be determined by the operator's visual inspection.
It is also possible to provide a sensor that detects that the clamp 1 is securely held by the inspector body 100.

With reference to FIG. 7, a limit switch 900 can be used as this sensor, for example. This limit switch 900 is embedded in the base 110, and the contactor 901 portion thereof is the base 11
It is arranged so as to slightly project to the front side of 0.
Then, when performing the inspection, the clamp 1 comes into direct contact with the contactor 901 when the clamp 1 is in the state shown in FIG. The limit switch 900 is input by the contact of the clamp 1 with the contactor 901. As a result, it is detected that the clamp 1 is sandwiched and held between the curved surface 311 and the leading surface 412, and as a result, the clamp 1 is of a predetermined type, and It can be seen that it is correctly attached to the predetermined position.

As described above, the limit switch 90
Even when 0 is provided, the clamp 1 is held by being sandwiched between the curved surface 311 and the upper surface 412, so that the clamp 1 moves in the direction in which it disengages from the inspector body 100 during inspection. And set the limit switch 900 to OF
It is possible to avoid the inconvenience of causing the F state. As a result, accurate inspection can be smoothly performed.

In the above embodiment, the base 110 is formed in a substantially key shape as shown in FIGS.
Although the inclined surface portion 115 is formed on the upper portion thereof, the shape of the inclined surface portion 115 may be formed so as to follow the outer shape of the clamp 1. By doing so, the clamp 1 can be more stably accommodated and held in the inspector body 100. This makes it possible to more effectively prevent the clamp 1 from coming off the inspector body 100 during the inspection.

Besides, various design changes can be made within the scope of the present invention.

[0073]

According to the first aspect of the present invention, when the wire harness is deployed on the inspection drawing board for inspecting the mounting of the insertable clamp, the wire harness is inserted into the correct position of the assembled wire harness. If the insertable clamp is not attached, the position of the insertable clamp and the inspector main body shifts, so it is obvious that the insertable clamp is not installed in the correct position. In addition, even if the insertable clamp is installed at the correct position of the assembled wire harness and the position of the insertable clamp and the inspection device body match, the external shape of the insertable clamp is inspected. If it does not correspond to the body of the device, it is not possible to hold the retractable clamp by the body of the inspection device. From this, it can be seen that the insertable clamp having the predetermined shape is not attached.

Therefore, it is determined whether or not the predetermined type of the insertable clamp is correctly mounted at the predetermined position, and whether the insertable clamp can be held by being sandwiched by the main body of the inspection device. It can be surely inspected. Moreover, since the insertable clamp is sandwiched between the first sandwiching surface portion and the second sandwiching surface portion, the insertable clamp can be reliably held regardless of the mounting direction of the insertable clamp. That is, regardless of the mounting direction of the insertable clamp, the insertable clamp does not move in the direction in which it disengages from the main body of the inspector or slips over during inspection. As a result, there is no need to perform correction work or the like due to the fitting type clamp coming off during the inspection, and the inspection work can proceed smoothly.

According to the invention of claim 2, the same effect as that of the invention of claim 1 can be obtained. That is, in the invention according to the present claim, the insertable clamp to be inspected enters the first and second sandwiching surface portions, and at this time, the protruding portion is fitted into the mounting recess of the insertable clamp. By mating, the 1st and 2nd clamping surface parts can be exactly contact | abutted to the outer peripheral surface of a fitting type clamp, and can be clamped. This shows that the correct type of snap-in clamp is installed in the correct position. That is, in the invention according to this claim, in order to detect that the correct type of the insertable clamp is mounted, the shapes of the first and second clamping surface portions are made to correspond to the outer shape of the insertable clamp. In addition, a simple structure is adopted in which a protruding portion is provided and is fitted with the fitting type clamp, and there is an advantage that the fitting inspection device for the fitting type clamp can be provided at low cost. is there.

According to the invention of claim 3, the same effect as that of the invention of claim 1 or 2 can be obtained. Particularly, in the invention according to the present claim, the first clamp arm and the second clamp arm are rotated by pressing the insertable clamp against the first clamp arm, whereby the first and second clamp arms are rotated. It can be clamped between the clamping surface portions. That is, there is an advantage that the fitting type clamp can be set on the main body of the inspection device with one touch to perform the inspection, and the inspection work can be smoothly performed. However, if the insertable clamp does not have a predetermined shape, the insertable clamp cannot be held between the two holding surface portions, and therefore, a different type of insertable clamp cannot be held. It can be seen that the clamp is not installed in the correct position.

According to the invention of claim 4, the same effect as that of the invention of claim 3 can be obtained. In addition, when the insertable clamp is set on the main body of the inspection device, the insertable clamp is pressed against the second holding arm so that the insertable clamp is inserted between the first and second holding surface portions. Even can't do this. That is, when setting the insertable clamp on the main body of the inspection device, the insertable clamp must be pressed against the first holding arm. Therefore, provisionally, by pressing the insertable clamp against the second clamping arm, the insertable clamp is caused to enter between the two clamping surfaces, and the retractable clamp is held between the protrusion and the second clamping surface. As a result, it is possible to eliminate the inconvenience of passing the inspection even though the fitting clamp is not the correct shape.
