Typically, various moving parts, such as door, hood, and tail gate panel parts, are assembled on the vehicle body. Among these panel parts, hoods have recently become larger and are being manufactured in clam shell types that are advantageous in terms of fuel efficiency and design.
Panel parts such as hoods can be assembled through a marriage process that loads an inner panel onto an outer panel, and a hemming process that hems the edges of the outer panel and inner panel.
In the marriage process, the outer panel is fixed to the marriage jig, and the inner panel is loaded onto the outer panel that has been fixed to the marriage jig. The marriage jig includes units such as alignment devices and locators for fixing the outer panel.

Referring to
The supporters 21 and locators 31 of the alignment units 20 are moved to a predetermined position along the forward-backward direction, the left-right direction, and the up-down direction by the multi-axis movement units 40 according to the component information of the hood assembly 1.
In this state, the hood outer panel 4 is loaded onto the first panel support part 23 of the supporters 21 and the second panel support part 33 of the locators 31 by a robot hanger (not shown).
The flange portion 7 of the hood outer panel 4 is guided downward through the guide bar 25 of the supporters 21 and can be loaded onto the first panel support part 23 and the second panel support part 33.
Then, the clamper 35 of the locators 31 clamps the flange portion 7 of the hood outer panel 4. The hood outer panel 4 is aligned to a predetermined position on the marriage jig frame 10 by the supporters 21 and locators 31.
As shown in
The vacuum cup modules 61 suck air through the air intake portion 65 and vacuum adsorb the flange portion 7 of the hood outer panel 4 through the suction cup 63. The suction cup 63 may be brought into close contact with the flange portion 7 of the hood outer panel 4 by the magnetic force of the magnet 67 applied to the flange portion 7.
After completion of vacuum adsorption of the flange portion 7 by the vacuum cup modules 61, the clamping of the clamper 35 is released, and the supporters 21 and the locators 31 are moved in a direction away from the flange portion 7 of the hood outer panel 4 by the multi-axis movement units 40.
As shown in
The pressing roller 73 of the roller modules 71 comes into rolling contact with the skin surface 4a of the hood outer panel 4, and applies pressure to the skin surface 4a, thereby inducing elastic deformation of the skin surface 4a. Simultaneously, the vacuum cup modules 61 induce elastic deformation of the flange portion 7 of the hood outer panel 4.
The pressure sensor 79 of the roller modules 71 detects the pressure of the pressing roller 73 and outputs the detected signal to the controller (not shown). The controller changes the position of the roller modules 71 according to the detected signal of the pressure sensor 79 and can control the pressure of the pressing roller 73 applied to the skin surface 4a.
Accordingly, by causing the vacuum cup modules 61 and the roller modules 71 to induce elastic deformation of the hood outer panel 4, the marriage path 9 of the hood inner panel 6 to be assembled with the hood outer panel 4 may be set. In other words, by spreading the end portion of the hood outer panel 4, i.e., the flange portion 7, the marriage path or gap 9 may be formed so that the hood inner panel 6 can move toward the inside of the hood outer panel 4.
Referring to
The vacuum cup modules 61 are moved backwards in a direction away from the flange portion 7 while releasing the vacuum adsorption of the flange portion 7. Additionally, the roller modules 71 are moved back to their original positions. Accordingly, the hood outer panel 4 is restored to its original shape as the external force caused by the vacuum cup modules 61 and roller modules 71 is removed.
The supporters 21 and locators 31 of the alignment units 20 are moved back to a predetermined position along the forward-backward direction, left-right direction, and up-down direction by the multi-axis movement units 40.
The supporters 21 and locators 31 support and clamp the flange portion 7 of the hood outer panel 4 by the operation mentioned above.
Thus, the marriage process of the hood outer panel 4 and the hood inner panel 6 is completed through a series of processes as described above.
Then, in the hemming process, when the hemming apparatus (not shown) hems the edge portions of the hood outer panel 4 and the hood inner panel 6, the assembly of the hood assembly 1 is completed.
According to an embodiment of the panel assemble apparatus 100 described so far, in the marriage process of the hood outer panel 4 and the hood inner panel 6, the alignment units 20 can be moved in multi-axis directions by the multi-axis movement units 40.
Therefore, the panel assemble apparatus 100 according to an embodiment can be commonly utilized in the marriage process for assembling hood assemblies 1 of different vehicle types and various designs.
Accordingly, according to the panel assemble apparatus 100 according to an embodiment, the design degree of freedom of the hood assembly 1 can be improved, and the initial investment cost of the marriage process equipment can be reduced.
Furthermore, the panel assemble apparatus 100 according to an embodiment can induce elastic deformation of the hood outer panel 4 and load the hood inner panel 6, thereby eliminating marriage interference between the hood outer panel 4 and the hood inner panel 6.
Accordingly, the panel assemble apparatus 100 according to an embodiment can solve the problem of line non-operation due to poor marriage between hood outer panel 4 and hood inner panel 6 and the problem of assemble quality of hood assembly 1.
Although the some embodiments of the present disclosure have been described above, the present disclosure is not limited thereto, and various modifications may be made within the scope of the claims, the detailed description of the present disclosure, and the attached drawings, which also fall within the scope of the present disclosure.
