technical field

The present invention relates to a processor for inspecting a camera module and an apparatus for inspecting a camera module including the processor. More particularly, the present invention relates to a processor for inspecting a camera module capable of picking, placing and automatically aligning a camera module through a clamp-type picking unit and managing the history of the camera module through a barcode scanner, And relates to a device for inspecting a camera module including the processor.

Background technique

With the development of smart devices, small-sized camera modules are more and more widely used. Recently, camera modules are even installed in vehicles or smart TVs, and portable terminals such as smartphones, tablets, and notebooks.

A general camera module is constructed to include a housing, a lens barrel in which a plurality of lenses are stacked, an image sensor such as a CCD or CMOS, a substrate on which the housing and the lens barrel and the image sensor are mounted, and a connection with the outside world. Connectors for electrical connections.

During the manufacturing process of the camera module, it is possible to check whether the assembled camera module is correctly assembled or whether the auto-focus function of the camera module works normally.

The inspection apparatus in the prior art adopts a method of inspection after the inspector directly and manually places the camera module in the socket. In this case, the camera module, especially the socket of the camera module, is often damaged.

In addition, problems such as inconvenience that an inspector needs to directly move the camera modules one by one, and an increase in inspection time have been increasingly raised.

In order to solve these problems, an automatic handler that automatically transfers the camera module is used; in the existing automatic handler, an observation system that confirms and adjusts the alignment state when picking up or placing the camera module is used.

However, due to the use of the observation system, the manufacturing cost increases, and the management points of the operator in terms of the system or control increase, thereby increasing the burden on the operator.

In addition, if the camera module is replaced, the information on the replaced module (such as reference image information) needs to be re-input into the observation system, and even if it is the same device, due to the difference in aperture value, illumination intensity, and distance of the observation system, , it often happens that reference image information needs to be input separately.

Therefore, when the number of devices on a production line increases, the operator's on-site management burden is further increased.

Here, referring to FIG. 4 , the camera modules CM waiting to be inspected by the inspection unit may be placed in the first accommodating part 110 , and the camera modules CM whose inspection has been completed by the inspection unit may be placed in the second accommodating part 150 .

In particular, the second accommodating portion 150 includes a first sub-accommodating portion 150a and a second sub-accommodating portion 150b, wherein the inspection unit determines that a good camera module is placed in the first sub-accommodating portion 150a, and the inspection unit determines that A defective camera module may be placed in the second sub-accommodating part 150b.

The number, type, arrangement, number of camera modules placed in the accommodating part, etc. of the accommodating parts may be appropriately changed as needed.

Referring again to FIGS. 1-3 , the picking unit 190 may pick up the camera module placed in the first accommodating part 110 and place the picked up camera module into the camera module socket of the inspection unit. When the inspection unit completes the inspection operation, the picking unit 190 may pick up the camera module again and place the camera module into the second accommodating part 150 .

Further, the pick-up unit 190 may be installed on the Y-axis extension frame 450 to reciprocate along the Y-axis direction Y, and may be installed to move along the Z-axis direction Z orthogonal to the X-axis direction X and the Y-axis direction Y. raised or lowered.

For reference, the X-axis and the Y-axis are axes that lie in the same horizontal plane and are horizontally orthogonal to each other. The Z axis is an axis perpendicular to the horizontal plane.

Specifically, the picking unit 190 may include a first picking device 200 , a second picking device 250 , a first raising and lowering cylinder 300 , a second raising and lowering cylinder 350 , and a Y-axis driver 400 .

The first picking device 200 can pick up the camera module placed in the first accommodating part 110, and place the picked up camera module into the camera module socket of the inspection unit.

Here, the first pick-up device 200 may include a first gripper 202 that picks up the camera module placed in the first accommodating portion 110, a first gripper cylinder 204 that drives the first gripper 202, and an auxiliary first gripper. The first sensor 206 of the operation of picking and placing the camera module of 202 .

The second picking device 250 may pick up the camera module for which the inspection unit has finished checking, and place the picked up camera module into the second accommodation part 150 .

Here, the second pick-up device 250 may include a second gripper 252 that picks up the camera module for which the inspection unit completes inspection, a second gripper cylinder 254 that drives the second gripper 252 , and assists in picking up the second gripper 252 . and a second sensor 256 to place the operation of the camera module.

The first raising and lowering cylinder 300 can raise and lower the first pickup device 200 along the Z-axis direction Z, while the second raising and lowering cylinder 350 can raise and lower the second pickup device 250 along the Z-axis direction Z. .

For reference, the positions of the first pick-up device 200 and the second pick-up device 250 may be reversely set as shown in the drawings. Of course, in this case, the first raising and lowering cylinder 300 and the second raising and lowering cylinder 350 are also arranged inversely to what is shown in the figures.

The Y-axis driver 400 may be installed on the Y-axis extension frame 450 to reciprocate Y along the Y-axis direction. That is, through the Y-axis driver 400 , the pick-up unit 190 can reciprocate in the Y-axis direction Y on the Y-axis extension frame 450 . Further, the first raising and lowering cylinder 300 and the second raising and lowering cylinder 350 may be installed on the Y-axis driver 400 .

Here, referring to FIGS. 5 and 6 , it can be determined that: through the first lifting and lowering cylinder 300 and the second lifting and lowering cylinder 350, the first pick-up device 200 and the second pick-up device 250 can move along the Z-axis direction Z, respectively.

Further, the first clamp 202 and the second clamp 252 may be installed at an acute angle with respect to the X-axis, respectively, and the jaws of each of the clamps 202 and 252 may be formed horizontally symmetrically.

Thanks to these features, the first clamp 202 and the second clamp 252 can pick up the camera module CM in an aligned state and maintain the aligned state until the camera module CM is placed.

Specifically, the first clamp 202 or the second clamp 252 picks up the camera module CM obliquely, thereby forming an acute angle with respect to the X-axis as shown in the drawing, so that the camera module CM is automatically mechanically aligned. Therefore, no separate viewing system or drive for aligning the camera modules CM is required.

Further, in the case of the first clamp 202 and the second clamp 252 , the camera module CM can be aligned only by replacing the clamp according to the size of the camera module CM, and thus does not need to be individually set.

Further, unlike methods such as vacuum suction, the first gripper 202 and the second gripper 252 may perform a picking operation without being affected by ambient temperature or humidity.

Thereby, the total processing time for transferring the camera module can be shortened, and the influence of vibration can be minimized by minimizing the driving of each member.

Specifically, the operation of picking up and placing the camera module by the picking unit 190 is as follows.

First, the tray unit 100 moves along the X-axis extension frame 500 from a standby position to be located below the pick-up unit 190 in the X-axis direction X, and the pick-up unit 190 moves to the camera to be picked up from the tray unit 100 along the Y-axis direction. above the module.

Then, when the first picker 200 is precisely located above the camera module to be picked up, the first picker 200 is lowered along the Z-axis direction Z to pick up the camera module, and raised again along the Z-axis direction Z. Afterwards, the picking unit 190 moves toward the upper side of the camera module socket of the inspection unit along the Y-axis direction Y, and then lowers along the Z-axis direction Z to put the picked up camera module into the camera module socket.

Here, in order to realize the precise operation of picking and placing the camera module through the picking unit 190, the movement of the tray unit 100 along the X-axis direction X, the movement of the picking unit 190 along the Y-axis direction and the Z-axis direction can be preset. coordinate value.

Further, as shown in the drawings, in order to achieve a more precise picking operation, the first picking device 200 and the second picking device 250 may include a first sensor 206 and a second sensor 256 respectively. Here, the first sensor 206 and the second sensor 256 may be, for example, camera sensors or remote sensing sensors.

The first sensor 206 and the second sensor 256 are used to assist the operation of picking up and placing the camera module by the first gripper 202 and the second gripper 252, respectively, and are therefore also removable from the first pick-up device 200 and the second pick-up device 250, respectively. . However, for ease of explanation, in the present invention, the situation that the first pickup device 200 includes the first sensor 206 and the second pickup device 250 includes the second sensor 256 will be described as an example.

When the inspection of the camera module is completed in the inspection unit, the judgment result that the camera module is good or defective is displayed on the display part (such as 1140 in FIG. module, and place the picked up camera module in the first sub-accommodating portion 150a or the second sub-accommodating portion 150b according to the judgment result whether the camera module is good or defective.

The Y-axis extension frame 450 extends along the Y-axis direction Y, and the pick-up unit 190 can be mounted on the Y-axis extension frame 450 . Therefore, the pick-up unit 190 can reciprocate in the Y-axis direction Y on the Y-axis extension frame 450 .

The X-axis extension frame 500 extends along the X-axis direction X, and the tray unit 100 can be mounted on the X-axis extension frame 500 . Therefore, the tray unit 100 can reciprocate in the X-axis direction X on the X-axis extension frame 500 .

The barcode scanner 550 may scan the barcode of the camera module picked up by the picking unit 190 .

Specifically, the barcode scanner 550 is disposed between the X-axis extension frame 500 and the Y-axis extension frame 450, and can scan the barcode of the camera module located below the pickup unit 190 and picked up by the pickup unit 190, thereby Get information about the camera module. Therefore, an operator or a manager can easily manage the history of camera module products, so that management efficiency can be improved.

Hereinafter, an apparatus 2 for inspecting a camera module according to another embodiment of the present invention will be described with reference to FIGS. 7-10 .

FIG. 7 is a perspective view illustrating an apparatus for inspecting a camera module according to another embodiment of the present invention. FIG. 8 is a schematic diagram illustrating the inspection unit of FIG. 7 . 9 and 10 are views illustrating operations of the camera module placement part of FIG. 8 .

For reference, the apparatus 2 for inspecting a camera module includes the processor 1 for inspecting a camera module as described above, and thus a detailed description of the processor will be omitted.

Referring to FIG. 7, an apparatus 2 for inspecting a camera module according to another embodiment of the present invention includes a processor 1 for inspecting a camera module as described above, an inspection unit 1120, a main body 1110, and a display portion 1140 .

Specifically, the main body 1110 provides a space including the inspection unit 1120 and the display part 1140, and may have a PC, a power supply, etc. embedded therein.

The inspection unit 1120 is a space for inspecting the camera module. Various inspections such as individual difference inspection, resolution inspection, focus inspection, image inspection, etc. can be performed at the inspection unit 1120, and inspection items can be adjusted as needed.

The display part 1140 is a part that outputs the inspection result of the camera module inspected in the inspection unit 1120, and displays corresponding information, thereby allowing the user to view the camera module for each inspection item performed in the inspection unit 1120 through the display. A good or defective judgment result is used to confirm a defective camera module.

Here, referring to FIG. 8 , a top view of the inspection unit 1120 is shown.

Specifically, a camera module may be placed on the inspection unit 1120, and various inspections may be simultaneously performed on the placed camera module.

For reference, as a camera module to be inspected by the apparatus 2 for inspecting a camera module according to another embodiment of the present invention, there may be, for example, a fixed focus (FF) type camera module with a fixed focal length, and a default focal length, But an autofocus (AF) type camera module in which the focal length can be changed by an actuator.

Here, the inspection unit may include a fixed table top 1122, a rotating table top 1123 mounted on the fixed table top 1122 to rotate in a normal direction or a reverse direction, a plurality of radially arranged on the rotating table top 1123 and having areas for placing camera modules. The camera module placement part 1124, a plurality of inspection modules 1125, 1126 and 1127 arranged radially on the fixed desktop 1122, and a driving unit (not shown) that rotates the rotating desktop 1123 in a normal direction or a reverse direction.

For example, FIG. 8 shows checking modules 1125, 1126, and 1127 for checking a total of 3 items.

Here, the first area 1121-1 is an area where a camera module is placed (loaded) or removed (dismounted) from the camera module placement part 1124, and the camera module can be supplied to the camera module placement part 1124 manually or automatically. Section 1124.

If the camera module is automatically supplied to the camera module placement portion 1124, the camera module receptacle 1124b may be an automatic opening and closing type of camera module receptacle 1124b - which is automatically closed by recognizing the normal placement of the camera module and upon completion of the opposite automatically turns on after the inspection of the incoming camera module.

The second area 1121-2 is an area in which the first inspection of the camera module is performed, the third area 1121-3 is an area in which the second inspection is performed on the same camera module, and the fourth area 1121-4 is in which the inspection of the same camera module is performed. The area where the third inspection is performed by the same camera module.

Here, the procedure for inspecting the camera module placed in the camera module placement section 1124 is as follows.

After the camera module CM is supplied via the camera module placement section 1124 located in the first area 1121-1, when the camera module placement section 1124 in which the camera module CM is placed moves (rotates by 90°) and reaches the second area 1121-2 , a camera module placement portion 1124 in which a camera module has not been placed is placed (rotated by 90°) into the first area 1121-1, and the first inspection of the camera module CM is performed in the second area 1121-2 At the same time, a new camera module can be placed. As the rotating tabletop 1123 is rotated by 90° in the same manner, the next camera module may be sequentially supplied to the camera module placement part 1124 .

When the third inspection of the initially supplied camera module CM is completed in the fourth area 1121-4 by repeating the above-mentioned operations, the camera module placement portion 1124 located in the fourth area 1121-4 is turned by 270° in the opposite direction. to be located in the first area 1121-1 again.

At this time, the camera module placement part 1124 in which the second camera module is placed is located in the fourth area 1121-4, so the third inspection of the second supplied camera module can be performed while the inspection-completed camera module CM is located in the first area. The camera module placement part 1124 of the area 1121-1 is removed and a new camera module is placed again.

As described above, the second area 1121-2, the third area 1121-3, and the fourth area 1121-4 are areas where inspections of placed camera modules are sequentially performed. For example, an individual difference inspection module 1125 may be provided in the second area 1121-2, a resolution and focus inspection module 1126 may be provided in the third area 1121-3, and an image inspection module 1127 may be provided in the fourth area 1121-4.

For example, the individual difference inspection module 1125 may be a device in which AWB correction and LSC correction are performed using a light source, and the resolution and autofocus inspection module 1126 may include an inspection part 1126a and a driver 1126b. For distance and long-distance inspection, the driver 1126b controls the movement of the inspection part 1126a. Further, the image inspection module 1127 may also include an inspection part 1127a having a graph and a driver 1127b for controlling the movement of the inspection part 1127a.

As described above, the apparatus 2 for inspecting a camera module according to another embodiment of the present invention has an advantage in that inspection modules (individual difference inspection apparatus, resolution and focus inspection apparatus, resolution and focus inspection apparatus, Image inspection equipment) is included in the inspection unit 1120, which can shorten the transmission time and standby time in the inspection area.

By increasing the number of inspection modules in the inspection area, the inspection efficiency of the camera modules can be further improved.

Then, referring to FIGS. 9 and 10, the operation of the camera module placement part 1124 of FIG. 8 is shown.

FIG. 9 shows a state where the camera module placement part 1124 applied to the inspection unit 1120 shown in FIG. 8 is in a horizontal mode, and FIG. state in straight mode.

Specifically, the camera module placement part 1124 may include a support plate 1124a that can be aligned horizontally or vertically, a camera module socket 1124b that is disposed on the support plate 1124a and the camera module is placed therein, and provides a driving force to drive The motor 1124c of the support plate 1124a.

Here, the horizontal mode means a state in which the support plate 1124a is aligned in the horizontal direction, and herein, the camera module placed in the camera module socket 1124b faces upward. Further, the vertical mode means a state in which the support plate 1124a is aligned in the vertical direction, and herein, the camera module placed in the camera module receptacle 1124b faces sideways.

Cell phones, tablets, and personal computers in which the camera module is actually installed are often used in a state where the camera module is placed vertically, not in a state where the camera module is placed horizontally; The difference in posture between the camera module and the camera module is placed vertically. Therefore, the inspection result of the camera module only in the state where the camera module is placed horizontally may not accurately reflect the actual use environment.

Therefore, according to the present invention, since the support plate 1124a can be aligned in the horizontal direction or the vertical direction, an inspection environment that most reflects the actual use environment can be realized.

By receiving a driving force from the motor 1124c, the support plate 1124a can be rotated between a horizontal mode and a vertical mode, and the rotation angle can be adjusted as desired.

More specifically, the support plate 1124a is connected with the motor 1124c through the pulley 1124d, thereby receiving a driving force from the motor 1124c.

That is, the pulley 1124d provided on one side of the support plate 1124a connects the support plate 1124a and the motor 1124c to transmit the driving force generated by the motor 1124c to the support plate 1124a, thereby enabling the support plate 1124a to be between the horizontal mode and the vertical mode. turn.

If the inspection of the camera module is performed only in the horizontal mode or the vertical mode, the motor 1124c may be controlled to provide only enough driving force to rotate the support plate 1124a from the horizontal mode to the vertical mode or vice versa.

Since the angle of gravity applied to the camera module may also be misaligned depending on the angle of the support plate 1124a on which the camera module is placed, unstable or inaccurate alignment of the support plate 1124a may result in differences in the posture of the camera module, resulting in Inaccurate inspection results.

Therefore, when the inspection of the camera module is performed only in the horizontal mode or the vertical mode, it is necessary to accurately align the support plate 1124a in the horizontal direction or the vertical direction. Further, in the case where a positive stopper is introduced to precisely align the support plate 1124a horizontally or vertically, every time the support plate 1124a is aligned horizontally or vertically, the support plate 1124a cannot Avoid collisions with positive stops. Such collision may cause noise and vibration, and in some cases, the attitude of the placed camera module may be changed due to the collision of the support plate 1124a and the positive stopper.

In the present invention, in order to accurately align the support plate 1124a in the horizontal direction or the vertical direction without introducing a positive stopper, a limit sensor may be used.

A limit sensor that limits the moving range of the support plate 1124a may be disposed on the other side of the support plate 1124a—wherein one side of the support plate 1124a is provided with a pulley 1124d.

When the support plate 1124a is precisely aligned horizontally or vertically, the limit sensor can generate a signal for fixing the posture of the support plate 1124a.

Further, according to another embodiment, the limit sensor may include a plunger 1124e, sensor parts 1124f and 1124f', the plunger 1124e is arranged on the other side of the support plate 1124a to rotate together with the support plate 1124a, and the sensor part 1124f and 1124f' are respectively disposed on the area where the plunger 1124e is located when the support plate 1124a is aligned in the vertical direction and the area where the plunger 1124e is located when the support plate 1124a is aligned in the horizontal direction.

As described above, the plunger 1124e is disposed on the other side of the support plate 1124a to rotate together with the support plate 1124a. For example, when the support plate 1124a is aligned in the horizontal direction, the plunger 1124e is aligned in the vertical direction, thereby being recognized by the first sensor portion 1124f; when the support plate 1124a is aligned in the vertical direction, the plunger 1124e is aligned in the horizontal direction. , thereby being recognized by the second sensor portion 1124f'.
