The body frame 1010 accommodates the driving unit 1020 and the moving head 1030 to provide a combined structure of the driving unit 1020 and the moving head 1030 and can provide a moving path, Guide grooves 1011 extending in the longitudinal direction of the body frame 1010 and being bent in the vertical direction at the end are formed on both sides of the width direction.

The driving unit 1020 is accommodated in the main frame 1010 and reciprocates along the internal structure of the main frame 1010 to generate and provide a driving force for moving the moving head 1030, A cylinder 1022, a support block 1021, and a lift rail 1023.

The support block 1021 is coupled to the cylinder 1022 at one side thereof and is reciprocated according to the driving force of the cylinder 1022. The cylinder 1022 is driven by a pneumatic or hydraulic pressure to generate a driving force in the longitudinal direction of the body frame 1010, And transmits the driving force of the cylinder 1022 to the moving head 1030 by contacting the other side with the moving head 1030 to be described later.

At this time, a lifting rail 1023 protrudes from a surface of the support block 1021 coupled to the movable head 1030, and is slidingly coupled with the movable head 1030, thereby forming a coupling structure with the movable head 1030 Not only adds a coupling force but also guides the movement of the movable head 1030 in the vertical direction.

The movable head 1030 moves along the support block 1021 slidingly coupled to one side and controls the movement path of the signal supply unit 1040 coupled to the other side. The rail 1010 includes rail grooves (not shown) and guide protrusions 1031, .

The rail groove is provided on the surface in contact with the support block 1021 in a shape corresponding to the structure of the lift rail 1023 and is slidably engaged with the lift rail 1023 to thereby move the movable head 1030 And the guiding protrusion 1031 is protruded in a cylindrical shape on both sides symmetrically in the width direction of the moving head 1030 and is guided along the guiding groove 1011 in a state of being fitted in the guiding groove 1011 Thereby guiding the movement of the movable head 1030 in the horizontal direction with respect to the support block 1021. [

The guide protrusion 1031 is a cylindrical protrusion protruding in a symmetrical shape on both sides in the width direction of the movable head 1030 and is inserted into the guide groove 1011. The guide path 1011 guides the movement path by the shape of the guide groove 1011 Loses.

The signal supply unit 1040 is coupled to the lower surface of the moving head 1030 and moves along the moving path of the moving head 1030 so as to contact the signal supplying portion M of the inspected object unloaded to the inspection plate 320 And provides the inspection object with an inspection signal provided by a signal generating device (not shown).

At this time, the signal supply unit 1040 is provided with a connector 1041 having a shape and structure corresponding to a socket or a pin-type signal supply unit M of the object to be inspected, and is contacted or inserted into the signal supply unit M, So that the image of the object to be inspected can be transmitted.

Further, when the connector 1041 is separated from the signal supply unit M after the inspection process is completed, a fixing member M for fixing the signal supply unit M is further provided so that a smooth inspection signal supply process can be implemented Of course.

The up-down operation of the signal supply unit 1040 will be described with reference to FIG.

The signal supply unit 1040 of the present invention is configured such that the driving force in accordance with the reciprocating movement of the cylinder 1022 is changed by the guide path of the guide groove 1011 and the guide path of the lift rail 1023, The signal supply unit 1040 coupled to the moving head 1030 also moves up and down according to the movement of the moving head 1030. Accordingly, the signal supply unit 1040 can be contacted or inserted into the signal supply unit M of the object to be inspected to supply the inspection signal.

The moving direction of the cylinder 1022 in the longitudinal direction is referred to as a first direction and the direction in which the cylinder 1022 is moved in the vertical direction is referred to as a first direction to explain how the driving force of the cylinder 1022 is changed along the guide groove 1011 and the elevating rail 1023. [ Assuming that the moving direction of the unit 1040 is a second direction and the direction in which the moving head 1030 is moved with respect to the supporting block 1021 (elevating rail 1023) is a third direction, And is formed to be close to the first direction or the second direction between the first direction and the second direction.

When the third direction is formed close to the first direction, the reciprocating distance of the cylinder 1022 dramatically increases relative to the moving distance of the moving head 1030, so that the reciprocating distance of the cylinder 1022 is utilized When the moving height of the moving head 1030 is adjusted, the height of the movable head 1030 can be adjusted more precisely.

On the other hand, when the third direction is formed close to the second direction, the moving distance of the moving head 1030 dramatically increases relative to the reciprocating distance of the cylinder 1022, Down height of the moving head 1030 can be adjusted with a small driving force or a small reciprocating moving distance of the cylinder 1022 by adjusting the height of the moving head 1030.

As the third direction becomes closer to the first direction which is the load transmission direction of the cylinder 1022 or the second direction which is the load transmission direction due to the ascending and descending operation of the moving head 1030, the load in the first direction and the second direction The load applied to the elevating rail 1023 by the moving head 1030 is greatly increased.

Therefore, it is preferable that the third direction is formed in a direction perpendicular to the resultant force direction of the load in the first direction and the load in the second direction.

The driving force of the cylinder 1022 transmitted in the first direction is determined such that the moving head 1030 moves in the sliding section of the guide groove 1011, (d ₁₎ for this movement may be a force and moving the head (1030) assumed that the force for moving the elevating section (d ₂₎ of the guide groove 1011, which, the size of the force is the sliding zone (d ₁₎ And the distance of the elevation section (d ₂ ).

In the drawing, the third direction is set to be orthogonal to the second direction for ease of fabrication, but the preferred third direction is a direction orthogonal to the resultant direction of the force as described above. However, since the ascending section d ₂ of the guide groove 1011 is formed at a relatively small distance compared to the sliding section d ₁ , the preferable third direction is greatly different from the direction orthogonal to the second direction shown in the figure The third direction may be set in a direction orthogonal to the second direction in consideration of the convenience of manufacturing. Thus, a discontinuous problem of the operation of the moving head 1030, a problem of abrasion of the bent portion, And the problem that the guide groove 1011 is deformed or broken can be alleviated.
