[

Reference numeral 123 in the figure denotes a vacuum port.

Hereinafter, the operation of the present invention will be described.

FIG. 12 is a perspective view showing a state in which the camera module is seated in the socket of the present invention, FIG. 13 is an image view showing a state in which the camera module is seated in the socket of the present invention, FIG. 14 is a perspective view When the camera module M is inserted into the module groove 121 and then the cylinder 200 is operated in a basic state in which the upper surface of the module guide bracket 120 is exposed as described above, 400 moves linearly horizontally and then vertically descends.

15 is a plan view of the present socket in a state in which the top plate is moved, Fig. 16 is a side view thereof, and Fig. 17 is a sectional view taken along the line BB of Fig. The pushbutton 230 connected to the rear of the cylinder 200 moves together and the pushbutton 230 is moved to the left and right sides of the pushbutton 230, The lifting and guiding bracket 240 connected by the connecting shaft 242 moves together.

The lifting guide bracket 240 moves while pushing the inner roller 252 located in the inner inclined groove 241. The inner roller 252 is positioned at the upper end of the inclined groove 241 at this time, The outer roller 251 is moved along the rail groove 131 of the guide bracket 130 because the outer roller 251 is connected to the outer roller 251 by the guide roller 250.

That is, while the outer roller 251 is moving in the horizontal section 132 of the rail groove 131, the inner roller 252 remains positioned at the upper end of the inclined groove 241.

The roller shaft holder 260 connected to the roller shaft 250 is also moved together with the movement of the elevation induction bracket 240 and the rollers 251 and 252 and the roller shaft 250, And the elevation guide block 300 connected by the elevation shaft 320 at the lower side of the top plate 400 also moves horizontally.

As a result, the horizontal movement of the cylinder 200 is transmitted through the push bracket 230, the lifting guide bracket 240, the inner roller 252, the roller shaft 250, the outer roller 251, the roller shaft holder 260, (400) and the elevation guide block (300) simultaneously.

The elevating guide block 300 stably supports the top plate 400 to maintain an accurate position. To this end, the elevating guide block 300 accurately slides due to the engagement of the fixed rail 310 and the movable rail 311, .

The outer roller 251 can not move any further horizontally and the inner roller 251 connected to the outer roller 251 can not be moved any more when the horizontal roller 251 continues the horizontal movement and the outer roller 251 completes the horizontal section 132 of the guide bracket 130. [ 252, the roller shaft holder 260, the top plate 400, and the elevation guide block 300 are also horizontally moved.

At this time, the pin block 430 and the lens push block 440 of the top plate 400 are positioned at the vertical upper end of the camera module M inserted into the module groove 121.

Even when the horizontal section of the rail groove 131 ends, the movement of the cylinder 200 continues without interruption, so that the inclined grooves 241 of the lift-up guide bracket 240 move while pushing the inner roller 252 downward The outer roller 251 is moved downward to the vertical section 133 of the rail groove 131 by the inner roller 252 pushed downward.

That is, even during horizontal movement, the inclined grooves 241 continuously move the inner roller 252 while pushing it forward and downward, and the outer roller 251, which is no longer moved horizontally, moves downward to the vertical section 133 The inner roller 252 and the roller shaft 250 are lowered together due to the combined action of the inclined grooves 241 of 45 ° and the rail grooves 131 continuing in the horizontal and vertical sections.

Therefore, as the cylinder 200, the push bracket 230, and the lifting guide bracket 240 are continuously moved horizontally, the rollers and the roller shaft 250 and the roller shaft holder 260 are lowered, The top plate 400 connected to the bottom plate 260 also descends.

Here, the top plate 400 is accurately guided by the lifting shaft 320 while falling down against the elasticity of the spring 330, so that the lifting guide block 300 is stopped at this time.

As a result, the entire horizontal movement of the cylinder 200 and the vertical movement of the top plate 400 are smoothly connected to each other by one operation, It will be lost.

15 is a cross-sectional view taken along the line CC of Fig. 15, showing the state in which the outer roller 251 is lowered to the lower side of the vertical section 133 of the rail groove 131, Fig. 19 is a cross- And the inner roller 252 is positioned on the lower side of the inclined groove 241.

Fig. 20 is an image diagram of Fig. 19 above.

Meanwhile, the above-mentioned top plate 400 and the like are moved horizontally and vertically, and at the same time, the camera module fixing means according to the present invention is operated together. FIGS. 21 to 24 illustrate the operation of the fixing means, Only the part of the fixing means is shown in three dimensions with the plate and module guide bracket removed.

21 is a basic state before the pin cylinder 610 is operated. As shown in FIG. 21, the first alignment piece 650 and the second alignment piece 660 are spaced apart from each other as much as possible. FIG. 22 shows a state The first link 620 and the second link 630 are also spaced apart from each other.

23 and 24 show a state in which the first alignment piece 650 and the second alignment piece 660 are moved forward by the operation of the pin cylinder 610 and the holding portions 670 are in contact with each other.

That is, when the rod 611 pushes the first link 620 by the operation of the pin cylinder 610, the lower cam 640 simultaneously connected to the first link 620 and the second link 630 is rotated The second link 630 moves toward the first link 620 along the guide groove 621 of the first link 620 so that the second link 630 moves in the direction opposite to the first link 620 .

This is because the engaging pin 642 of the cam 640 is fitted in each of the pinholes 643 of the first link 620 and the second link 630 to rotate the cam 640 while the first link 620 is pushed, So that the second link 630 is simultaneously moved.

The movement of the first link 620 and the second link 630 is represented by the movement of the first alignment piece 650 and the second alignment piece 660 on the upper side, M) by aligning and fixing them.

The fixing unit including the pin cylinder 610, the cam 640, the first link 620 and the second link 630, the first alignment piece 650 and the second alignment piece 660, The top plate 400 is vertically lowered by the continuous movement of the cylinder 200 and the lens push block 440 of the top plate 400 presses the camera lens The pin block 430 is connected to the circuit pattern of the camera module M. [

In this state, the test is performed by an electrical signal. When the test is completed, the cylinder 200 retracts back due to the action of the cylinder 200, and the top plate 400 and the roller shaft holder 260 And then the top plate 400, the elevation guide block 300, the elevation guide bracket 240, etc. are horizontally moved rearward and returned to the original position.

Since the top plate 400 is always upwardly urged by the spring 330, when the cylinder 200 is retracted, the inclined groove 241 pushes up the inner roller 252, It is more smoothly moved upward by the elasticity.

A magnet 510 is embedded in the side surface of the push bracket 230 and the elevation induction bracket 240 so that the sensing of the magnet 510 by the movement of the cylinder 200 is performed by the sensor housing 600 And the operation of the cylinder 200 and the like can be controlled according to the detection signal.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, Embodiments incorporating replaceable components as equivalents in the components of the claims may be included within the scope of the present invention. For example, the push bracket and the cylinder bracket may be integrally formed as necessary, and the structure of the push bracket may be added to form the cylinder.
