Description

Slim type positioning stage device {Manual stage of fixing device}

The present invention relates to a slim-type positioning stage having a slim height to enable tilting, rotation, and movement of the upper plate to determine the position of the upper plate equipped with a camera module.

Recently released portable devices such as smartphones, tablets, laptops, etc. or CCTVs are released in the form of a camera and are configured to capture still images and videos. The performance of these cameras is gradually improving for high-resolution and high-definition photographing results, and the size of the camera is being reduced so that it can be placed in a device that is miniaturized.

These cameras support the lens that collects the light of the image, the image sensor that converts the image into an electrical signal, the image sensor, and are directly connected to the PCB and the external backed chip that serve as a path to input and output electrical signals to the outside. It consists of an FPCB, etc. connected to each other, and such a configuration is integrally combined is referred to as a camera module.

The FF type (Fixed Focus Type) is a module fixed with one focal length, and the AF type (Auto Focus Type) has a basic fixed focal length, but current or voltage The focal length can be changed by applying to the lens unit to operate a driver configured in the lens unit. A general AF type camera module consists of a lens system with a plurality of lenses, and a VCM (Voice Coil Motor) is used as a driver. And it is configured to adjust the optical focal length by moving each lens and changing its relative distance.

On the other hand, as the function of the camera module is improved and the size is reduced, high accuracy and reliability of the operation inspection of the camera module is required. Here, the operation inspection of the camera module varies depending on the type of the camera module, but is generally open/ Short test, power line resistance measurement, current consumption test, input/output leakage current test, etc. are performed, and defects are determined through these tests.

In addition, the camera module outputs the camera module through a fixed focus of the lens and image inspection through a fixed focusing adjustment inspection that determines the coupling depth by precisely rotating the lens unit to match a specific fixed focal length with the sensor and housing unit before shipping. By analyzing the image precisely, it checks whether there is a defect in the unit pixel in the sensor or a defect such as a scratch or particle in the lens, and through AF drive inspection, the operation of the auto focus function implemented by operating the actuator of the camera module itself is located. It is inspected by a crystal device.

As shown in Fig. 1, the inspection of the presence or absence of such abnormalities is performed by connecting at least two positioning devices (10, 10', 10``) to each other in a stacked structure, and through this, the X-axis and Y-axis of the camera module And the Z-axis and the like are moved to be variable to perform the inspection.

However, in the case of this inspection method, as shown, the adjusters (11, 11', 11``) for determining the position of the camera module by moving each positioning device are located in different directions and released as a product. At the same time, the fixing screws (13, 13'') for fixing after the movement are also present in different positions, so the operator has the inconvenience of adjusting the position of the camera module while moving in various directions. At the same time, there was a problem that the inconvenience of requiring a space in the work space coexisted.

In order to solve this problem, the Korean registration office No. 20-0491352 (announcement date: 2020.03.25.)'positioning stage provided with fixing means', which is a prior art improved by the present applicant, is disclosed.

Referring to FIG. 2, referring to this prior art configuration, after adjusting the moving distance between the upper body and the lower body, it includes a fixing means for fixing, wherein the fixing means is fixedly installed on the outer surface of the upper body by a fastening means. The movable body and the fixed body and the outer surface fixedly installed on the outer surface of the lower body by the fastening means are rotatably inserted through the movable body, and one end is rotatably inserted into the fixed body, so that the It includes a distance adjusting body for moving forward or backward by pulling or pushing the upper body coupled with the moving body.

Thus, the upper body slides forward (X-axis direction) or rearward (Y-axis direction) around the lower body according to the rotation direction of the rotating body, so that the position for inspecting the camera module is easily determined and the first By making it possible to fix the outer surface of the rod penetrating into the through hole through the fixing hole formed in the protrusion by pressing, the position of the fixing means can be changed even if a plurality of positioning devices are connected to each other to have a stacked structure. It was installed to be biased, so that it was possible to realize the effect of bringing the convenience of the worker as well as the utilization of the work space.

However, this prior art has a problem in that the upper body can be moved in the X-axis or Y-axis direction, but the upper body cannot be tilted or rotated, and thus there is still inconvenience in terms of utilization.

Hereinafter, a slim-type positioning stage apparatus (hereinafter, simply referred to as'stage') according to the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Fig. 3, the stage 1 according to the present invention is largely a body part 100, a tilting member 200, a rotating member 300, a first moving member 400, and a second moving member. Includes 500.

In more detail, the body portion 100 has a form in which a plurality of powders are stacked on each other, as shown in FIGS. 3 to 7, but the tilting member 200, the rotating member 300, and the first Position of the camera module (not shown) to be inspected by the inspection means (not shown) by tilting (TILT), rotation (ROTATION), and movement (MOVE) by the moving member 400 and the second moving member 500 A ball bearing 110, a lower plate 120, a middle plate 130, a tilting plate 140, and an upper plate 150 are included as a configuration to enable determination.

For example, the ball bearing 110 is provided between the top plate 150 and the tilting plate 140 so as to have a length in the vertical direction, but the top having a ball shape is rotatably coupled with the bottom of the top plate 150 , The lower part is fixedly installed on the tilting plate 140 (see FIG. 4).

The upper portion of the ball bearing 110 coupled to the lower portion of the upper plate 150 is rotatably coupled to the center of the sphere compared to the total area of the upper plate 150 so that the tilting member 200 and the rotating member 300 described later are During operation, the upper plate 150 has a structure in which the upper plate 150 can be tilted or rotated with an upper portion of the ball bearing 110 as a center axis ('Z axis' shown in FIG. 4).

The lower plate 120 is formed to have a shape of a plate as a whole, but the lower part is detachably coupled with an inspection means (not shown), and the position of the camera module provided on the upper surface of the upper plate 150 is determined by the corresponding inspection means. Let the test take place.

At this time, the upper surface of the lower plate 120 is coupled to the lower surface of the middle plate 130 so as to reciprocate in the Y-axis direction so that the upper plate 150 can move in the Y-axis direction by the operation of the second moving member 500. It is preferable to do, and a detailed description thereof will be described in more detail in the second moving member 500 to be described later.

In addition, the second movable member 500 is rotatably installed on the side of the lower plate 120 so that the middle plate 130 can reciprocate in the Y-axis direction with respect to the lower plate 120 by the rotation. do.

The middle plate 130 is formed to have a shape of a plate as a whole, but the lower portion thereof is coupled to the lower plate 120 in a stacked manner to reciprocate in the Y-axis direction as described above, and a tilting plate 140 is stacked on the upper portion. Combine in form.

At this time, the lower surface of the tilting plate 140 coupled to the upper portion of the middle plate 130 is coupled to the upper surface of the middle plate 130 so as to be reciprocally moved in the X-axis direction, and the tilting plate is formed by a first moving member 400 to be described later. It is preferable to allow the 140 to move in the X-axis direction, and a detailed description thereof will be described in more detail in the description of the first moving member 400 to be described later.

In addition, the first moving member 400 is rotatably installed on the side of the middle plate 130 so that the tilting plate 140 can reciprocate in the X-axis direction with respect to the middle plate 130 by the rotation. .

The tilting plate 140 is formed to have a shape of a plate as a whole, and is movably coupled to the middle plate 130 in a stacked form.

In the upper part of the tilting plate 140, the lower part of the ball bearing 110 is inserted and fixed in the center of the tilting plate 140 compared to the total area, and a pair of moving holes 149 on the side where the tilting member 200 is installed. The perforations are formed so as to be adjacent to each other and connect with the upper surface of the tilting plate 140.

A plurality of guide balls 143 are provided in the moving hole 149, and the guide ball 143 is applied to the external force of the tilting rod 240 entering and leaving the moving hole 149 through the insertion hole 211. As a result, it is pushed in one direction (toward the top of the tilting plate) or returned to the other direction (toward the side of the tilting plate) so that the top plate 150 can be tilted with the ball bearing 110 as the center (see FIG. 4).

On the upper surface of the tilting plate 140, a pair of return balls 147 are provided to protrude upwardly so as to be symmetric with the moving hole 149, and each of the return balls 147 is inside the tilting plate 140. The upper plate 150 inclined by the tilting member 200 is contracted/relaxed by the elastic force of the first elastic body 145 having an elastic restoring force in the vertical direction and has a structure capable of returning to its original state (FIG. 6 and See Fig. 8)

In addition, a gap between the upper surface of the tilting plate 140 and the lower surface of the upper plate 150 is maintained between the pair of return balls 147, but the upper plate 150 is provided with a ball bearing 110 by a rotating member 300 to be described later. A ball (BALL)-shaped spacing tool 141 is provided to be rotatable on the top of the tilting plate 140 so as to protrude upward so that it can be easily rotated when rotating around.

That is, the tilting plate 140 has a pair of moving holes 149 formed on the side of the tilting plate 140 on one side of the upper surface of the tilting plate 140 based on an arbitrary center line CL. A plurality of guide balls 143 are formed to be connected to the upper surface, and a plurality of guide balls 143 are provided in contact with each other in each of the moving holes 149, and a pair of return balls 147 are formed on the other side of the center line CL, It is to allow a gap maintaining unit 141 to be disposed between a pair of the return balls 147.

In addition, the reason that the return ball 147 has a ball shape is that while the upper plate 150 is inclined in the direction in which the moving hole 149 is formed, the lower surface of the upper plate 150 maintains a limited protrusion length. When the ball 141 cannot be in close contact with the top, the top of the return ball 147 can perform the function of the gap maintaining unit 141 instead, so that the top plate 150 easily rotates even in a tilted state. To be able to do it.

For this reason, it is also possible to omit the interval maintenance tool 141 in the present invention as necessary.

The upper plate 150 is generally formed in the shape of a plate, but the lower portion thereof is rotatably coupled with the upper portion of the ball bearing 110, and a camera module to determine a position is detachably provided on the upper surface.

A protruding piece 151 for protruding outwardly from the top plate 150 in the direction of the rotating member 300 installed on the side of the top plate 150, that is, the tilting plate 140 to be described later. This is formed so that the upper plate 150 can rotate around the ball bearing 110 in the pushing direction of the rotation shaft 340.

In addition, the tilting member 200 includes a tilting block 210 and a pair of adjustment heads in a configuration for allowing the top plate 150 to be tilted in the TX or TY direction, and the adjustment head in the present invention As shown, each of the TX-tilting head 220 to tilt the top plate 150 in the TX direction and the TY-tilting head 230 to tilt the top plate 150 in the TY direction are respectively described. Note that, in order to clarify the gist of the control head of the present invention, the description of the TX-tilting head 220 will replace the description of the TY-tilting head 230.

For example, the tilting block 210 is fixedly installed on the side of the tilting plate 140 on which a pair of moving holes 149 is formed, but the outer surface thereof communicates with each of the moving holes 149 and at the same time adjusts the head (TX-tilting head and A pair of insertion holes 211 into which TY-tilting heads) are respectively inserted are perforated adjacent to each other.

The TX-tilting head 220 is rotatably inserted into any one of the pair of insertion holes 211 and applies an external force to the guide ball 143 in the moving hole 149 by the rotation of the top plate 150. This is a configuration for moving in the'+TX' and'-TX' directions. (See FIGS. 3 and 4)

To this end, a rotating body is provided on the outer surface of the TX-tilting head 220 so as to rotate in the forward (clockwise) and reverse (counterclockwise) directions, and the inside thereof is forward (moving hole) according to the rotation direction of the rotating body. Direction) or rearward (rotator direction) is provided so that the plurality of guide balls 143 can be pushed or returned to their original position.

For example, as shown, when the rotating body of the TX-tilting head 220 is rotated in the forward direction, the tilting rod 240 in the TX-tilting head 220 can be inserted into the moving hole 149. It protrudes to, and pushes out any one of the guide balls 143 provided so as to contact each other inside the moving hole 149 by the protrusion.

In this process, a plurality of guide balls 143 are guided by a moving hole 149 so that the guide balls 143 in contact with the lower surface of the upper plate 150 protrude to the upper surface of the tilting plate 140 and the upper plate 150 The ball bearing 110 is centered in the direction of'+TX' and the top plate 150 is inclined.

On the contrary, when the rotating body of the TX-tilting head 220 is rotated in the reverse direction, the upper plate 150 is lowered in the'-TX' direction by the reverse order, and this sinking force is applied to the tilting plate 140 described above. The lower surface of the upper plate 150 is pushed out by the elastic force of the first elastic body 145 of the return ball 147 of any one of the pair of return balls 147 provided to return to its original position or tilted downward from its original position. It is what makes it possible to lose.

At this time, the inclination of the top plate 150 inclined in the TX direction or the TY direction can be inclined within a range in which the guide ball 143 does not deviate through the moving hole 149 formed on the upper surface of the tilting plate 140. It is desirable to do.

On the other hand, the TY-tilting head 230 also has the same structure and action relationship as the TX-tilting head 220 described above, but there is a difference only in the direction in which the top plate 150 is inclined (TY direction). Is replaced by the description of the TX-tilting head 220.

In addition, the rotating member 300 is installed on the side of the tilting plate 140 and rotates in a configuration for rotating the top plate 150 in the X-axis or Y-axis direction around the'Z axis' of the ball bearing 110. It includes a block 310, a rotating head 320 and a rotating bush 330. (See FIG. 6)

For example, as shown, the rotating block 310 is fixedly installed on the side of the tilting plate 140 that is symmetrical to the above-described tilting block 210.

On the outer surface of the rotating block 310 not in contact with the tilting plate 140, a pair of adjustment pieces 311 are formed so as to be adjacent to each other to form a space 313 inside the space 313 The rotation shaft 340 coupled with the top plate 150 may be disposed therein.

At this time, a through hole 315 is perforated to face each other in each of the adjustment pieces 311, so that a rotating head 320 is inserted and installed in one of the through holes 315, and a rotating bush 330 is provided in the other. It is desirable to insert and install.

Similar to the above-described TX-tilting head 220 or TY-tilting head 230, the rotating head 320 has a rotatable rotating body formed on its outer surface, and inside the rotating rod according to the rotation direction of the rotating body ( It has a structure that enters and exits the rotation head 320 so that the protrusion length of the 321 can be varied.

At this time, the end of the rotation rod 321 is installed to face the outer surface of the rotation shaft 340 located in the space part 313 to push the rotation shaft 340 according to the protruding length of the rotation rod 321 It is desirable to allow the plate 150 to rotate in the pushing direction.

The rotating bush 330 stably supports the upper plate 150 rotated in the X-axis direction by supporting the other side of the rotating shaft 340 while the rotating rod 321 pushes one side of the rotating shaft 340 described above. It is a configuration for fixing and simultaneously pushing the top plate 150 in the Y-axis direction.

To this end, the rotating bush 330 is also provided with a rotating body in which a rod having a predetermined length is formed on its outer surface, and the rod is rotated in the lateral direction of the rotating shaft 340 through rotation of the rotating body rotating in a forward or reverse direction. It has a structure that can protrude to and push the rotation shaft 340 in the Y-axis direction.

Of course, the rod that pushes the rotation shaft 340 in the Y-axis direction can limit its rotation radius through the support of the rotation rod 321 provided on one side of the rotation shaft 340.

In this case, a second elastic body 333 for supporting the rod by an elastic force may be further provided inside the rotation bush 330, and the second elastic body 333 is, in particular, a rotation rod 321 in the rotation shaft 340. After pushing in the X-axis direction, it can be easily used if fine adjustment is required in the corresponding direction.

That is, in the process of performing the inspection of the camera module by the rotation rod 321 pushing one side of the rotation shaft 340 to rotate the top plate 150 in the X-axis direction, the operator In this case, when the second elastic body 333 is not provided, the rod of the rotating bush 330 supporting the other side of the rotating shaft 340 is manually adjusted to rotate the rotation. There is an inconvenience of controlling the distance at which the rod 321 can further move in the X-axis direction.

Thus, by providing the second elastic body 333 so that the rod can move finely inside the rotating bush 330, the rotating rod 321 is X-axis even when the rotating bush 330 is not adjusted by its elastic force. By finely moving in the direction so that the top plate 150 can move in the corresponding X-axis direction, this problem can be solved.

Of course, the second elastic body 333 may be further provided with the second elastic body 333 inside the rotating bush 330 to improve the above-described problem so that fine adjustment in the Y-axis direction may be possible. Due to the pair of second elastic bodies 333, the fixing force of the upper plate 150 is slightly lowered, so that interference may occur in the detailed inspection of the camera module, preferably the rotating bush 330 or the rotating head ( It can be said that it is preferable to use the second elastic body 333 provided in only one of 320).

In addition, the first moving member 400 moves the tilting plate 140 itself around the middle plate 130 in the X-axis direction so that the upper plate 150 connected to the tilting plate 140 is moved in the corresponding X-axis direction. It includes a first fixing body 410, a first adjusting body 420, and a first moving body 430 in a configuration to be able to move to.

For example, one side of the first fixing body 410 is protruding so as to connect with the outer surface of the middle plate 130, but the first adjusting body 420 is rotatably installed on the other side.

The first adjusting body 420 installed in the first fixing body 410 has a first volume body 421 that can rotate in a forward or reverse direction on one outer surface, and a rotation direction of the first volume body 421 on the other side. Accordingly, the first rod 423 has a structure in which the protruding length of the first rod 423 can be varied in and out of the first control body 420.

At this time, the end of the first rod 423 is rotatably coupled with the first moving body 430 as shown, and the protruding length of the first rod 423 according to the rotation direction of the first volume body 421 It is preferable to be installed so as to have a structure capable of pushing or pulling the first moving body 430 by being variable.

The first moving body 430 is rotatably coupled to the end of the first rod 423, but its outer surface is formed to be connected to the tilting plate 140 so that the first rod 423 is pushed or pulled to move the tilting body. The upper plate 150 combined with the plate 140 is reciprocated in the X-axis direction.

In addition, the second moving member 500 moves the middle plate 130 itself around the lower plate 120 in the Y-axis direction, as shown in FIGS. 7 and 8, so that the middle plate 130 and the The connected tilting plate 140 is configured to move in the corresponding Y-axis direction, and includes a second fixing body 510, a second adjusting body 520, and a second moving body 530.

For example, the second fixing body 510 has one side protruding to connect with the outer surface of the lower plate 120, and the second adjusting body 520 is rotatably installed on the other side.

The second adjusting body 520 installed on the second fixing body 510 has a second volume body 521 that can rotate in a forward or reverse direction on one outer surface, and a rotation direction of the second volume body 521 on the other side. Accordingly, the second rod 523 has a structure in which the protruding length of the second rod 523 can be varied so that the second controller 520 can enter and exit the inside/outside.

At this time, the end of the second rod 523 is rotatably coupled with the second moving body 530 as shown, and the protruding length of the second rod 523 according to the rotation direction of the second volume body 521 It is preferable that it is installed to have a structure capable of pushing or pulling the second moving body 530 by being variable.

The second moving body 530 is rotatably coupled to the end of the second rod 523, but the outer surface thereof is formed to be connected to the middle plate 130 so that the second rod 523 is pushed or pulled to move the middle By allowing the tilting plate 140 coupled with the plate 130 to reciprocate in the Y-axis direction, the top plate 150 coupled with the tilting plate 140 can reciprocate in the corresponding Y-axis direction.

The stage 1 according to the present invention having the configuration as described above has a stacked structure so that a plurality of plates have a slim height, different from the conventional one, but the camera module to be inspected by the inspection means is provided on the top thereof.
