Abstract
An inspection object clamping unit is disclosed which can clamp the inspection object quickly and firmly regardless of the size of the inspection object. The clamping unit is mounted on a test object, and both ends are connected to the guide, the up / down rail which is lifted along the guide, and the upper guide disposed to be spaced apart from the up / down rail by a predetermined distance on the upper part of the up / down rail. And, connected to both ends of the up / down rail is moved left and right by lifting both ends of the up / down rail with the same force and height to maintain the horizontal level of the up / down rail irrespective of the size of the inspection object And a lifting unit for bringing the inspection object mounted on the up / down rail into close contact with the upper guide, and driving means connected to the lifting unit to move the lifting unit left and right.
Description
The present invention relates to an inspection object clamping unit, and more particularly, when the inspection object is loaded in the three-dimensional shape measuring apparatus and moved to the inspection position through the transfer device, the inspection object can be moved to the inspection position in a fixed state. To an object clamping unit.
In general, at least one printed circuit board (PCB) is provided in an electronic device, and various elements are mounted on the printed circuit board. In order to inspect defects of such devices, a three-dimensional shape measuring device is usually used.
The three-dimensional shape measuring apparatus generally measures or inspects a printed circuit board transferred to a predetermined place by a transfer device that loads and transfers a printed circuit board as an inspection object.
An inspection object clamping unit is used to transfer the inspection object to the inspection position while the inspection object is fixed in the three-dimensional shape measuring apparatus.

Referring to FIG. 1, in a general inspection
However, the
Therefore, in recent years, as the size of the
Accordingly, an object of the present invention is to provide an inspection object clamping unit capable of quickly and firmly clamping an inspection object regardless of the size of the inspection object.
The inspection object clamping unit according to an embodiment of the present invention includes an inspection object mounted thereon, both ends being connected to a guide, an up / down rail which is lifted along the guide, and the up / down rail on top of the up / down rail. The upper guide is arranged to be spaced apart from the predetermined interval, and is connected to both ends of the up / down rails and moved left and right to raise both ends of the up / down rails with the same force and height to level the up / down rails And a lift unit for keeping the inspection object mounted on the up / down rail in close contact with the upper guide, and driving means connected to the lift unit to move the lift unit left and right.
For example, the lifting unit includes a left and right moving member connected to the driving means, an up / down shaft protruding from both end portions of the left and right moving members, and the up / down rail so that the up / down shaft is inserted. It is formed to be inclined in the same direction at both end portions of the left and right moving member is moved along the up / down shaft which is moved in conjunction with the left and right moving member as the left and right moving member is moved left and right by the driving means along the up / down And an up / down hole portion for elevating the down rail.
Here, the up / down rail may further include a receiving groove for accommodating the left and right moving members.
For example, the left and right moving members are formed to be shorter than the length of the accommodating groove, and when connected to the driving means and moved left and right by a predetermined distance, one side or the other side is constrained to one side or the other side of the accommodating groove. And a body part no longer moved left and right, and a connection part coupled to both sides of the body part and protruding from the up / down shaft.
On the other hand, the lifting unit further includes a roller rotatably installed on the up / down shaft in order to reduce the friction force generated between the surface forming the up / down hole portion and the up / down shaft.
As described above, the inspection object clamping unit according to the exemplary embodiment of the present invention is formed such that a pair of up / down holes are inclined upward in the same direction at both end portions of the up / down rails so that the left and right moving members are driven by the driving means. When moving to the up / down shaft both sides of the up / down rail by the same force and the same height is raised to clamp the inspection object between the upper guide and the up / down rail, the length of the inspection object Even if it is formed shorter than the distance from one end of the up / down rail to the center portion, it is possible to firmly clamp the inspection object without a gap between the inspection object and the up / down rail.
Therefore, the clamping unit according to an embodiment of the present invention can quickly and firmly clamp the inspection object between the up / down rail and the upper guide irrespective of the size of the inspection object, thereby greatly reducing the setting time of the inspection object. It can reduce the measurement or inspection time of the inspection object.
