Description

A dimensional check device for automobile headlamps housing cover lens

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting dimensions of automobile parts, and more particularly, to an apparatus for inspecting dimensions of a cover lens on the front of a headlamp housing.

Headlamps in automobiles play an important role in both function and design of automobiles. Headlamps provide the driver's visibility at night and provide the ability to alert other vehicles or pedestrians of the vehicle's presence. Headlamps occupy a large proportion as a design element to the extent that they are said to be the eyes of a car. Partial change (Facelift) It is a major part to which changes are applied even in models.

Before the 1970s, incandescent light bulbs called filaments were used in headlamps, but they were limited as headlamps due to their short lifespan and low luminance. Halogen lamps developed later had the advantages of wide light diffusion, easy visibility, and miniaturization. Afterwards, HID (High Intensity Discharge) lamps and recently LED lamps are rapidly taking their place. LED lamps not only consume less power and have a long lifespan, but also provide a wide degree of design freedom in terms of design, making it possible to design lamps of various shapes. In addition, various sensor components are being integrated into the headlamp module as it rapidly converges with autonomous driving technology.

As LEDs are used in headlamps and autonomous driving technology is merged, the area where the headlamps are exposed to the exterior of the vehicle is gradually increasing, and the importance of design is increasing. In addition, the demand for machining dimensional accuracy of the finished headlamp housing is also increasing gradually.

<First embodiment>

1 to 3 are views showing a major part of a dimension inspection apparatus according to a first preferred embodiment of the present invention. Referring to this, the dimension inspection apparatus according to the present invention includes a dummy panel 10 and a gauge holder 20 . The dummy panel 10 reproduces the body of the vehicle where the headlamp is installed. The shape of the edge portion 10e of the dummy panel 10 has the same specification as that of the vehicle body panel. The cover lens L, which is the object to be inspected, is installed at a predetermined position adjacent to the edge portion 10e (see Fig. 2).

The dimension inspection apparatus according to the present invention is configured to measure a dimension at a predetermined inspection position to determine whether the cover lens L satisfies a specification. The dimension inspection apparatus determines whether the distance between the edge portion of the vehicle body panel and the edge portion of the cover lens L at a predetermined position satisfies a predetermined dimension, and determines whether the surface of the vehicle body panel and the surface of the cover lens L are continuous and smooth. It is measured whether or not a predetermined height is satisfied to form a surface. Hereinafter, the inspection for measuring the gap between the edges between the vehicle body panel and the cover lens is called a “gap check”, and the inspection for measuring whether the surface of the cover lens has a predetermined height is called a “flush check”.

The gap check is performed by measuring the distance from a predetermined position on the dummy panel 10 to the edge portion of the cover lens L. The flush check is performed by measuring the distance from a predetermined height outside the cover lens L to the test position. A gauge holder 20 for installing a gauge for measuring a distance is installed on the dummy panel 10 . In this embodiment, the gauge holder 20 has a bent shape as shown. The mounting portion 20 includes a gauge port 21 for a gap check for mounting the gauge G1 for a gap check and a gauge port 22 for a flush check for mounting the gauge G2 for a flush check. Referring to FIG. 2 , a cylindrical central hole 21h is formed in the gauge port 21 for checking the gap. The length measurement rod (R1) of the gauge (G1) for the gap check is installed to be capable of moving forward and backward through the central hole (21h). The gauge port 21 for checking the gap is disposed so that the end of the length measuring rod R1 faces the edge of the test object L. As the gauge G1 for checking the gap, various types of gauges capable of measuring length may be used, and may be an analog or digital device. The gauge port 22 for flush check also has a cylindrical central hole 22h. The length measuring rod R2 of the flush check gauge G2 is installed in the central hole 22h to enable forward and backward movement.

One measurement module CM becomes a unit that performs a gap check and a flush check at a predetermined inspection position. The gauge G1 for the gap check and the gauge G2 for the flush check are installed toward the predetermined inspection position so that the gap check and the flush check can be performed at the predetermined inspection position.

<Second embodiment>

Next, a dimension inspection apparatus according to a second embodiment of the present invention will be described with reference to FIGS. 4 to 8 .

The measurement module CM of the dimension inspection apparatus according to the second embodiment of the present invention is configured differently from the dimension inspection apparatus according to the first embodiment. In the first embodiment shown in Fig. 2, the gauge G1 for checking the gap is installed on the same height in the lateral direction of the object L to be inspected. In contrast to this, the gauge G1 for checking the gap of the second embodiment is not installed at the same height as the inspection object L in the lateral direction, but is installed at a higher position. That is, as shown in FIG. 5 , the gauge G1 for checking the gap is installed at a position higher than the inspection object L by the height H1. This is for a case where it is necessary due to a constraint due to a positional relationship with other structures added to the dummy panel 10 or other structural constraints in the design of the panel 10 .

In more detail, the measuring module (CM) of the dimension inspection apparatus according to the second embodiment is flush with the adapter 100 for the gap check gauge for mounting the gauge (G1) for the gap check as shown in FIG. Includes a gauge port 32 for flush check for mounting the gauge (G2) for the check. The gauge port 32 for flush check is supported at a predetermined height from the dummy panel 10 by a bracket 33 supporting it. A cylindrical central hole 32h is formed in the flush check gauge port 32 . The central hole (32h) is installed along the direction toward the surface of the inspection object (L). The length measuring rod (R2) of the flush check gauge (G2) is installed so as to move forward and backward on the central hole (32h), and the distance from the surface of the inspection object (L) is measured.

In addition, the measurement module CM includes an adapter 100 for a gap check gauge (hereinafter, sometimes abbreviated as “adapter”) for mounting the gauge G1 for a gap check. The adapter 100 provides a degree of freedom in structural design so that the gauge G1 for a gap check can be installed at a position raised by a predetermined height H1 from a predetermined measurement position.

6 and 7, the adapter 100 includes a body 110 constituting a main body, a sliding block 120, a gauge port 130 for a gap check, a cover 140, and a moving hook 150. do. Hereinafter, for convenience, based on the coordinate system shown in FIGS. 6 and 7, the +X-axis direction is forward, the -X-axis direction is rearward, the +Y-axis direction is left, the -Y-axis direction is right, and the +Z-axis direction is upward, The -Z-axis direction is set downward for explanation. The body 110 has a rectangular shape elongated in the front-rear direction. A sliding groove 111 recessed to a predetermined depth along the front-rear direction is formed on the upper surface of the body 110 . The body 110 is fixed at a predetermined position on the dummy panel 10 by a separate fastening means. The sliding block 120 is slidably installed in the sliding groove 111 . The outer periphery of the sliding block 120 has a shape to fit into the sliding groove (111). A probe 121 in contact with an object to be inspected is coupled to the front of the sliding block 120 . In the present embodiment, the probe 121 has a bent portion 121a that extends downward by a predetermined length and is bent forward again, and an end of the bent portion 121a is in contact with the edge portion of the cover lens as an inspection object. The probe 121 is integrally formed with the sliding block 120 and slides in the front-rear direction. A first spring 161 is interposed between the sliding block 120 and the body 110 to apply a force pushing them to each other. The first spring 161 acts as a force for pushing the sliding block 120 forward while being built in the first spring receiving groove 112 formed in the body 110 . The first spring accommodating groove 112 is disposed below the sliding groove 111 and is formed to open forward of the body 110 . A handle 122 extending upward a predetermined length is coupled to the upper portion of the sliding block 120 . The upper end of the handle 122 is exposed upward through the long hole 141 formed in the cover 140 . The user may retract the sliding block 120 by pulling the exposed upper handle 122 by hand. After completing the gap check in the dimensional inspection process, this operation may be performed to return the sliding block 120 back to its original position.

The gauge port 130 for a gap check is coupled to the rear of the body 110 . In the center of the gauge port 130 for gap check, a cylindrical central hole 130h is formed in the front-rear direction, and the length measuring rod R1 of the gauge G1 for gap check passes through the central hole 130h to advance and retreat. It is installed movably (see Fig. 5). In the first embodiment, the gap check is made in such a way that the length measuring rod R1 is in direct contact with the edge portion of the measuring object L, whereas in the second embodiment, the length measuring rod R1 is the measuring object L. Rather, there is a difference in that the gap check is made indirectly in a way that is in contact with the rear surface of the sliding block 120 . Hereinafter, as in the first embodiment, a measuring module in which the gap check is performed by directly contacting the gauge G1 for a gap check to the measurement object L is referred to as a direct measurement module, and as in the second embodiment A measurement module in which the gauge G1 for checking the gap is in contact with the adapter 100 for checking the gap without being in direct contact with the measurement object L to perform the gap check is referred to as an indirect measurement module. The indirect measurement module can be usefully used when it is difficult to install the gauge for gap check at a height parallel to the surface of the inspection object L, that is, when it is difficult to apply the direct measurement module.

A moving hook 150 for fixing the retracted handle 122 is configured on the upper surface of the cover 140 . The movable hook 150 is installed to be movable in the left and right directions. The movable hook 150 includes a hook body 151 elongated in the left and right direction and a hook portion 152 protruding forward from the hood body 151 . A lateral groove 142 for guiding the left and right movement of the hook body 151 is formed on the upper surface of the cover 141 . A bolt hole 151a formed in a lateral direction is formed in the hook body 151 , and the hook body 151 is slidably supported while the fastening bolt 153 is inserted into the bolt hole 151a. A second spring 162 is interposed between the hook body 151 and the fastening bolt 153 . The second spring 162 acts to push the hook body 151 to the right with respect to the fastening bolt 153 . A second spring accommodating groove (not shown) for accommodating the second spring 162 is formed in the hook body 151 . The ring portion 152 has a shape that protrudes forward of the hook body 151 . The ring portion 152 is formed with a ring groove 152a having a shape that is opened in the right direction, and an inclined surface portion 152b obliquely inclined in the right direction. In a state in which the sliding block 120 is retracted, the handle 122 portion is inserted into the ring groove 152a, so that the sliding block 120 may be positioned at the rear. This state is shown in Fig. 8(b).

In order to check the gap, the sliding block 120 must advance so that the probe 121 and the object L are in contact. For this, the user may push the moving hook 150 to the left. When the moving hook 150 moves to the left, the handle 122 is separated from the ring groove 152a, and the sliding block 120 moves forward by the restoring force of the first spring 161 . This state is shown in Fig. 8(a). A gap check is performed in such a way that the length measuring rod R1 of the gap check gauge G1 is in contact with the rear surface of the sliding block 120 while the probe 121 is in contact with the object L to be inspected.

After the gap check is completed, in order to position the sliding block 120 to the rear again, the user may pull the handle 122 back. As the handle 122 moves backward, it comes into contact with the inclined surface portion 152b, and the handle 122 pushes the moving hook 150 to the left by the force pushing it back. When the handle 122 comes to the rearmost position, the moving hook 150 moves to the right by the action of the second spring 162 , and at this time, the handle 122 is accommodated in the ring groove 152 and the handle 122 . remains fixed at the rear (see Fig. 8(b)).
