3 is an exploded perspective view illustrating the alignment module according to an embodiment of the present invention. 4 is a cross-sectional view of a portion of the alignment module cut in the lateral direction;

2 through 4, the aligning module 40 is configured to cooperate with the driving of the arms 32 and 34 of the driving module 30 so as to bring the first part into close contact with the guide part 28, .

The alignment module 40 includes an alignment plate 44, a pusher 48 and an elastic member 49.

The alignment plate 44 is coupled to the arm 32 of any one of the arms 32 and 34 and moved together with the arm 32. [ Preferably, the alignment plate 44 may be coupled to the lower end of the arm 32 by a fastening screw or the like.

A portion of the alignment plate 44 is exposed from the arm 32 when the alignment plate 44 is engaged with the lower surface of the arm 32.

The alignment plate 44 has the cam protrusion 41 and the engaging member 42.

The cam protrusion 41 is formed in a portion of the alignment plate 44 that is exposed without being covered by the arm 32 and the cam protrusion 41 is formed in a protruding shape protruding from the upper surface of the alignment plate 44.

The cam protrusion 41 may be integrally formed with the aligning plate 44 or may be fabricated as a separate part from the aligning plate 44 and assembled with the aligning plate 44.

When viewed in plan, some of the side surfaces of the cam protrusion 41 are chamfered to form a chamfered portion 41a (see FIG. 4), which forms a chamfered portion in the cam protrusion 41, The pusher 48 of the alignment module 40 will be retracted to increase the spacing with the first component when widened.

The engaging member 42 is formed on the upper surface of the guide plate 44 and the engaging member 42 is provided on the rear side of the cam protrusion 41 . The long axis of the engaging member 42 formed in a rectangular bar shape is disposed in a direction parallel to the driving direction of the arms 32 and 34. [

The engaging member 42 may be coupled to the aligning plate 44 by a fastening screw or the like, but the engaging member 42 may be integrally formed on the upper surface of the aligning plate 44 in a protruding shape.

The latching member 42 allows the elastic member 49 to be described later to elastically support the pusher 48. [

The pusher 48 moves in a direction toward the first component corresponding to the movement of the alignment plate 44 coupled to the arm 32. [ The pusher 48 is moved, for example, in a direction close to the guide portion 28 of the support module 20 or in a direction away from the first component.

The pusher 48 includes a push body 46 and a push rod 47.

The push body 46 is formed, for example, in a hexahedral block shape, and the push body 46 is disposed on the upper surface of the alignment plate 44.

The push body 46 is formed with a concave cam groove 46a. The cam groove 46a is formed in a concave shape from the lower surface of the middle push body 46 facing the upper surface of the alignment plate 44 and the cam projection 41 formed on the alignment plate 44 is formed in the cam groove 46a .

The volume of the internal space of the cam groove 46a is formed larger than the cam protrusion 41 so that the cam protrusion 41 can flow inside the cam groove 46a.

On the other hand, the cam groove 46a which is in contact with the chamfered portion 41a of the cam projection 41 is formed with an inclined surface 46b.

Since the chamfered portion 41a of the cam protrusion 41 is in contact with the inclined surface 46b of the cam groove 46a, the pushing body 46 is moved in the direction perpendicular to the moving direction of the cam protrusion 41 And is moved in one direction.

The push rod 47 is formed on the front surface of the push body 46 and the push rod 47 is formed into a rod shape protruding from the push body 46. [

The push rod 47 is a portion that is in direct contact with the first component. At the tip of the push rod 47, an inclined surface 47a is formed which is in contact with the first component when viewed in plan.

The elastic member 49 is interposed between the rear surface opposed to the front surface of the push body 36 opposed to the push rod 37 and the engaging member 42.

The elastic member 49 may be made of various members that generate an elastic force, but in an embodiment of the present invention, the elastic member 49 may include, for example, a coil spring.

One end of the elastic member 49 is coupled to the groove formed in the rear surface of the push body 46 and the other end opposite to the one end of the elastic member 49 is engaged with the engaging member 42, .

When the distance between the arms 32 and 34 of the drive module 30 is narrowed, the push body 46 advances toward the first part, at which time the push rod 47 formed on the push body 46 is pushed toward the first part And moves the first component in a vacuum-adsorbed state toward the guide portion 28 of the support module 20.

At this time, since the push rod 47 presses the first component by the elastic force of the elastic member 49, an excessive force is prevented from being applied to the first component so that an excessive force is applied to the first component or the push rod 47 It is possible to prevent the first part or the push rod from being damaged.

Meanwhile, the base body 10 has a hole 13 for guiding the push rod 47 as shown in FIG. 1, so that the push rod 47 can reciprocate linearly along a designated path.

Hereinafter, operation of a module test socket according to an embodiment of the present invention will be described.

Figs. 5 and 6 are plan views for explaining the operation of the test socket for testing the module first part. Fig.

First, the first component is disposed on the fixed plate 21 of the support module 20 to perform the test of the first component. The first part can be placed on the stationary plate 21 by hand or by a device providing the first part.

After the first part is placed on the fixing plate 21 and a vacuum is provided through the vacuum port 23, a vacuum is formed in the vacuum hole 22 communicating with the vacuum port 23, And is temporarily fixed on the fixing plate 21 by vacuum pressure.

The drive unit 31 of the drive module 30 operates after the first component is disposed on the fixed plate 21 and the distance between the arms 32 and 34 becomes narrow.

When the distance between the arms 32 and 34 is narrowed by the drive unit 31, the alignment plate 44 coupled to the arm 32 is also moved with the arm 32. [

The urging force of the elastic member 49 of the pusher 48 causes the pusher 48 to advance forward toward the first part while the cam protrusion 41 formed on the aligning plate 44 is moved, The rod 47 moves the first part to the guide part 28 while being contacted with the first part adsorbed by the vacuum pressure on the fixing plate 21 of the support module 20.

The push rod 47 moves the first part to the guide part 28 by using the elastic force of the elastic member 49 so that the push rod 47 does not excessively press the first part.
