[0034] A contact inspection device according to an embodiment of the present invention will be described in detail with reference to FIGS.
[0035] Fig. 1 is a perspective view of a contact inspection device according to an embodiment of the present invention, Fig. 2 is an enlarged view of a portion of the contact inspection device shown in Fig. 1, and Fig. 3 and Fig. 4 are side views of the contact inspection device shown in Fig. 1, with Fig. 3 showing the open state and Fig. 4 showing the closed state. Fig. 5 is a diagram for explaining the operation of the contact inspection device shown in Fig. 1.
[0036] Referring to FIG. 1, a contact inspection device according to an embodiment of the present invention includes support bases 10 and 20, a contact inspection module 30, a crank module 40, and a driving cylinder 60.
[0037] The supports 10 and 20 include a horizontal support (e.g., first support) 10 and a vertical support (e.g., second support) 20 coupled to each other, and the horizontal support 10 can be fixed to a surface (e.g., the ground or a table) via a fixing member 12. The angle formed between the vertical support 20 and the horizontal support 10 may be a right angle, but is not limited to this and may be any of various angles.
[0038] The contact inspection module 30 includes an inspection terminal 32 that comes into contact with an inspection target 90, such as a display module, for inspection and that comes into direct contact with a product. The contact inspection module 30 may be equipped with various electrical circuits required for inspection. The contact inspection module 30 may also include a height adjustment screw 34 that allows the relative height of the inspection terminal 32 to be adjusted.
[0039] The contact inspection module 30 is coupled to a drive cylinder 60. The drive cylinder 60 includes a piston rod 62 that can reciprocate hydraulically, and the end of the piston rod 62 is rotatably coupled to the contact inspection module 30 using a bearing, etc., so that the contact inspection module 30 can be moved, for example, in a predetermined direction. As shown in the drawing, the piston rod 62 may be inclined rather than parallel to the contact inspection module 30.
[0040] The drive cylinder 60 is connected to the vertical support 20 at an angle and is connected to a rotation axis 70 of the vertical support 20 by a bearing or the like so that it can rotate around the axis. In a similar manner, the piston rod 62 is also connected to the contact inspection module 30 so that it can rotate around the axis of the contact inspection module 30, which is parallel to the axis 70 of the vertical support 20.
[0041] The contact inspection module 30 is connected to the horizontal support base 10 through a crank module 40. Referring to FIG. 2, the crank module 40 has a double crank structure and includes two pairs of rod members 42 and four pairs of connecting members 50. The rod members 42 are of the same length and are installed parallel to each other. Each rod member 42 is rotatably connected to the horizontal support base 10 and the contact inspection module 30 through a pair of connecting members 50. For example, according to one embodiment of the present invention, each connecting member 50 includes a connecting bolt 52, 54, 56, which includes a head 52, a bearing connecting portion 54, and a threaded portion 56. The threaded portion 56 of the connecting bolt 52, 54, 56 is fixed to one of the contact inspection module 30 and the horizontal support base 10 and can be rotatably connected to the rod member 42 through a bearing 58 connected to the bearing connecting portion 54. Therefore, when the contact inspection module 30 moves, the rod member 42 can rotate around the axis of the connecting bolts 52, 54, 56 connected to the horizontal support base 10 and the axis of the connecting bolts 52, 54, 56 connected to the contact inspection module 30, allowing the contact inspection module 30 to maintain its parallelism.
[0042] Hereinafter, the operation of the contact inspection device according to one embodiment of the present invention will be described in detail with reference to FIG.
[0043] 5, the standby state before the start of the inspection is the "open" state, in which the piston rod 62 of the driving cylinder 60 moves toward the body of the driving cylinder 60, i.e., the length exposed to the outside is shortened. At this time, the contact inspection module 30 can be maintained parallel to the horizontal support 10 by being connected to the crank module 40, and can be inclined relative to the piston rod 62 of the driving cylinder 60.
[0044] When an inspection object 90 such as a display module arrives, the inspection terminal 32 of the contact inspection module 30 must be brought into contact with the object 90 to perform the inspection. The inspection object 90 is placed at a position lower than the inspection terminal 32 and positioned outside.
[0045] For this reason, when hydraulic pressure or the like is applied in the open state to push and move the piston rod 62 outward, the contact inspection module 30 connected to the piston rod 62 moves outward, lowering its height and approaching the inspection target 90. At this time, since the piston rod 62 is connected to the contact inspection module 30 at an angle, the pressure applied by the piston rod 62 to the contact inspection module 30 also flows in a diagonal direction. Since the contact inspection module 30 is connected to the crank module 40 in a double crank structure, the contact inspection module 30 always maintains a parallel state before, during, and after movement.
[0046] The contact inspection module 30 is moved until the inspection terminal 32 of the contact inspection module 30 comes into contact with the inspection target 90, and then stopped, thereby entering a "closed" state. In this state, the inspection target 90 is inspected through the inspection terminal 32.
[0047] If the height of the inspection terminal 32 is not correct in the closed state, the height of the inspection terminal 32 can be adjusted using the height adjustment screw 34.
[0048] In this way, the contact inspection module 30 can approach and apply pressure in an inclined direction toward the object to be inspected 90 while maintaining parallelism, so that the inspection terminal 32 can contact the object to be inspected 90 while applying uniform pressure, thereby improving the reliability of the inspection.
[0049] For example, in the case of a display module, terminals that must be contacted may be arranged in multiple rows, and in this case, if the test terminal 32 applies different pressure to different rows of the display module, an error may occur in the test results. However, in this embodiment, the contact test module 30 always maintains parallelism, so that uniform pressure can be applied to all rows, improving reliability.
[0050] In addition, in this embodiment, the piston rod 62 of the drive cylinder 60 applies a diagonal force to the contact inspection member 30 to move it, so that a greater force can be applied than when the contact inspection member 30 is moved by pushing it in a horizontal direction, thereby providing stable contact with the inspection object 90.
[0051] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, which are merely presented to enable those skilled in the art to easily understand and implement the present invention.
[0052] Although the present invention has been specifically described with reference to the embodiments, those skilled in the art may make various modifications in form and specific content without departing from the concept and scope of the present invention as defined in the following claims.
