The determination unit 12 analyzes the weight detected by any one of the plurality of sensors within the preset error range using the weight information of the body parts included in the design information of the body parts. It can be determined that the component is normally seated on the plurality of protrusion fixing portions 22 to 25.

In addition, when the determination unit 12 is analyzed that the coupling information related to the distance measured by the sensor provided on the lower surface of the vehicle body part inspection jig 20 is included within a preset error range, the vehicle body part to be inspected has a plurality of projections. It may be determined that it is normally seated on the fixing parts 22 to 25.

In addition, the determination unit 12 determines that the inspected body part is normally seated on the plurality of protrusion fixing parts 22 to 25 when it is analyzed that the area where the inspected body part contacts the vehicle body part inspection jig is equal to or larger than the preset area. can do.

At this time, when it is determined that the vehicle body part to be inspected is normally seated, the controller 16 may control the driving of the operation lever 21 to couple the vehicle body part to be inspected and the plurality of protrusion fixing parts 22 to 25. . The operation lever 21 is a component for operating the plurality of projection fixing portions 22 to 25 at the same time.

By analyzing an abnormally seated region (section) in the analysis unit (not shown), the problem may be solved more quickly.

According to the exemplary embodiment of the present application, the magnetic force generating unit 13 may generate a magnetic force acting on an attractive force to the vehicle body part to be seated on the plurality of protrusion fixing units 22 to 25.

For example, even if the vehicle body part to be inspected is coupled to the plurality of protrusion fixing parts 22 to 25, a phenomenon in which a predetermined angle is twisted due to an external force that may be generated in the component to be inspected itself is applied to the body part inspection jig 20. This can happen. As such, when the vehicle body part to be inspected is deviated by a predetermined angle, a test performed by applying an electric signal that can be inspected through the plurality of protrusion fixing parts 22 to 25 or a light source test such as an LED is not properly performed. Therefore, the test operation is not made smoothly, there is a problem that the yield can be reduced. Accordingly, the magnetic force generating unit 13 is fixedly coupled to the plurality of protrusion fixing units 22 to 25 without angular shifting during the test whether the body parts to be inspected seated on the plurality of protrusion fixing units 22 to 25 are defective. In order to prevent it from moving, it is possible to generate a magnetic force that applies an attractive force to the vehicle body part to be seated on the plurality of projection fixing portions 22 to 25.

In other words, the vehicle body part inspection device 10 may not only check whether the body part to be inspected and the plurality of protrusion fixing parts are correctly coupled, but also include a test performed by applying an electric signal, an LED headlight test for a vehicle, and the like. You can check for defects.

For example, the magnetic force generating unit 13 may be disposed on at least one of the surfaces corresponding to the hollow portion of the vehicle body part inspection jig 20 (that is, the surfaces corresponding to the front / rear / left / right directions respectively). Can be arranged. In this case, the magnetic force generating unit 13 can generate magnetic force with respect to the side surface of the vehicle body under test.

The controller 16 may control the operation of the magnetic force generator to be ON when the vehicle body to be inspected is normally seated on the plurality of protrusion fixing units 22 to 25. When the magnetic force generating unit 13 is in the ON state, the magnetic force generating unit 13 can generate a magnetic force that applies an attractive force to the component to be inspected. In addition, when the magnetic force generating unit 13 is in the ON state, the control unit 16 may control the operation of the operation lever for coupling the vehicle body to be inspected and the plurality of protrusion fixing units 22 to 25 to ON. In addition, the control unit 16 may control the operation of the operation lever 21 to be OFF in order to separate the inspected vehicle body component and the plurality of protrusion fixing units 22 to 25 after the inspected vehicle body component.

In addition, the controller 16 may differently control the type of the magnetic field generated from the magnetic force generator 13 according to the test progress state of the vehicle body to be inspected, for example. Here, the type of magnetic field may include at least one of the strength, frequency, time, and pattern of the magnetic field.

For example, the test progress state of the vehicle body to be inspected is illustratively a first state, a state in which a normal seated vehicle body part and a plurality of protrusion fixing units are coupled to each other, and an electrical test provided in the plurality of protrusion fixing units. A state in which a test is performed by applying a test electrical signal to a vehicle body part to which the unit is connected, that is, a state in which an electrical signal test is performed on the vehicle body to be inspected may be included. In addition, the test progress state may include, for example, a separation movement state for separating the vehicle body inspection jig 20 from the vehicle body to be tested as a second state.

At this time, the controller 16 controls the type of the magnetic field to the first type when the test progress state of the vehicle body to be inspected is the first state, and the test progress state of the vehicle body component to be tested is the second state. In this case, the magnetic field type can be controlled by the second type.

The magnetic force generating unit 13 generates a magnetic force (a weak magnetic force) corresponding to the first type when the test progress state of the vehicle body under test is in the first state, thereby testing the vehicle body component inspection based on the test electrical signal. Signal interference due to magnetic forces during performance can be minimized to obtain more accurate test results.

According to one embodiment of the present application, the irradiation unit 14 may generate matching information related to the vehicle body part and the vehicle body part inspection jig corresponding to the design information of the vehicle body part. For example, the irradiation unit 14 may be positioned to be spaced apart from the vehicle body part inspector jig 20 by a predetermined area. In addition, the irradiation unit 14 may be included in the vehicle body part inspection jig 20.

In one example, the irradiation unit 14 may include an imaging unit and a laser irradiation unit. The photographing unit may generate matching image information. In addition, the laser irradiation unit may generate digitized matching data information.

The photographing unit may generate matching image information photographing the inspection vehicle part. In addition, the photographing unit may generate matching image information obtained by photographing the vehicle body part jig 20 to be inspected. In addition, the photographing unit may generate matching image information photographing a combination of the vehicle body part to be inspected and the vehicle body part jig 20 to be inspected. In addition, the photographing unit may generate matching image information photographing a situation before the vehicle body part to be inspected and the vehicle body part jig 20 are coupled to each other.

The determination unit 12 may perform a comparative analysis with reference reference image information preset based on the matching image information generated from the photographing unit. The reference matching image information may be image information corresponding to the case where the determination unit 12 determines that the vehicle body to be inspected is normally seated on the vehicle body inspection jig 20.

For example, the determiner 12 may extract a feature point for the acquired matching image information. The determination unit 12 may calculate the similarity by comparing the feature point extracted from the reference matching image information with the feature point extracted from the acquired matching image information. If the calculated similarity is greater than or equal to a preset range, the determination unit 12 may determine that the inspected vehicle body part corresponding to the acquired matching image information is normally seated. In contrast, when the similarity obtained through the image feature point extraction similarity calculation is greater than or equal to a preset range, the determination unit 12 may determine that the vehicle body part at a specific point is abnormally seated.

In addition, the irradiating unit 14 may include a second irradiating unit to check the gap gap between the assembled vehicle body parts. In this case, the second irradiation unit may be a taper gauge, an ultrasonic wave, or a laser sensor. The second irradiation unit may be a unit for checking the clearance gap between the assembled vehicle body parts.

The second irradiation unit may be inserted into a space where the assembled first vehicle body part and the second vehicle body part are coupled to each other to sense a gap gap between the first vehicle body part and the second vehicle body part.

The determination unit 12 may determine whether the clearance gap measured from the second irradiation unit is included within a preset range.

Three-dimensional shape information is generated using the combination information of the model-elements, and rendered based on the information to display a model that can be visually checked by a user through a display device such as a computer.

Here, the node represents a position in space, and the edge is used as an element constituting the polygon. One polygon may be defined as node and edge information. When polygons meet polygons, shared nodes and edges are shared by each polygon. A polyhedron represents a mass in space composed of a plurality of polygons, and object information (name or index) is set in the polyhedron.

The virtual modeling information generator 17 may provide the virtual vehicle body part inspection jig 50 and the virtual body to be inspected part 60 to the user terminal 30.
