Example

1 is a schematic configuration diagram showing a device for inspecting a wound material according to an embodiment of the present invention, and FIGS. 2 and 3 are views for explaining examples of using the device for inspecting a wound material of FIG. 1.

First, the winding material 51, which is to be wound up to be used in a subsequent step from the preceding step and is to be provided to the subsequent step, may include a metal thin plate, a textile fabric, a thin film battery, and the like. Here, if there is a defect in the material 51 itself is wound may affect the subsequent process. That is, if scratches or foreign substances are adsorbed on the surface of the winding material 51, or there is a defect in the pattern, or if the winding material 51 is bent or folded, there is a serious effect on the subsequent process. It can be done. Therefore, it is preferable to perform inspection on the winding material 51 using the inspection apparatus 100 of the winding material of the present invention mentioned when winding up the winding material 51 so that it can be used for a subsequent process.

In addition, when using the inspection apparatus 100 mentioned above, it can also test whether the material 51 which winds up is wound correctly. That is, even when the material 51 to be wound is wound from the first roller 53 to the second roller 55 at an angle, it may affect the subsequent process. Since it can test to the state of the width direction in which 51 is wound, it can also test whether the material 51 is correctly wound up from the 1st roller 53 to the 2nd roller 55. FIG.

1 to 3, the inspection apparatus 100 for winding material uses a first roller 53 and a second roller 55 to form a material 51 in a film form (as a winding material, hereinafter 'material'). To check whether the material 51 mentioned above is defective when the material 51 is wound from the first roller 53 to the second roller 55 so as to be used in a subsequent process. And an image generator 11, 13, 15, an image processor 17, a marking processor 19, and the like.

In detail, the image generators 11, 13, and 15 may include an upper image generator 11, a lower image generator 13, and a side image generator 15. The upper image generating unit 11 generates an upper image of the material 51, and the upper image generating unit 11 forms a line perpendicular to the direction in which the material 51 is wound on the upper part of the material 51. A scan for generating the top image is provided. That is, as shown in FIG. 2, the upper image generating unit 11 is provided to scan in the form of a line the width direction of the material 51 perpendicular to the longitudinal direction, which is the winding direction of the material 51. Thus, the upper image generating unit 11 generates an upper image of the material 11 by performing a scan in the form of a line perpendicular to the direction in which the material 51 is wound. The lower image generating unit 13 generates a lower image of the material 51 and forms a lower image of the material 51 in a line perpendicular to the direction in which the material 51 is wound at the lower part of the material 51. A scan for generating is provided. Here, the upper image generator 11 generates an image on the upper portion of the material 51, and the lower image generator 13 generates an image on the lower portion of the material 51, except that the lower image generator ( Also in the case of 13), the width direction of the material 51 perpendicular to the longitudinal direction, which is the winding direction of the material 51, as in the upper image generating unit 11 is provided to scan in a line form. Accordingly, the lower image generator 13 generates a lower image of the material 51 by performing a scan in a line shape perpendicular to the direction in which the material 51 is wound. The side image generating unit 15 generates a side image of the material 51 on the side of the material 51, and thus the material 51 in the form of the same line as the thickness direction of the material 51 on the side of the material 51. A scan for generating the side image of the image) is provided. That is, the side image generation unit 15 is provided to scan in the form of a line in the same direction as the thickness direction of the material 51, as shown in FIG. In particular, the side image generation unit 15 may be provided only on one side of the material 51, or in some cases may be provided on both sides of the material 51.

As mentioned, the image generating unit 11, 13, 15 includes the upper image generating unit 11, the lower image generating unit 13, and the side image generating unit 15, so that the winding of the material 51 is reduced. When made, an image of each of the upper part of the material 51, the lower part of the material 51, and the side surfaces of the material 51 may be generated in real time. In addition, since the image generating units 11, 13, and 15 are scanned in the width direction of the material 51, it is possible to confirm whether the material 51 to be wound is properly wound as mentioned above. In other words, when the material 51 is not wound correctly and is wound slightly at an angle, the image generating units 11, 13, and 15 may check in real time that the material is wound out of the correct width direction.

In addition, the image generators 11, 13, and 15 may scan the material 51 using the cameras 11a, 13a, and 15a, which scan the material 51, and the cameras 11a, 13a, and 15a. ) May be provided with optics 11b, 13b, 15b that provide light. Here, the optics 11b, 13b, and 15b may mainly include a light emitting diode. Thus, each of the upper image generator 11, the lower image generator 13, and the side image generator 15 may include cameras 11a, 13a, and 15a and optics 11b, 13b, and 15b. .

The image processor 17 is a normal image for each of the upper image, the lower image and the side image of the material 51, and the upper part of the material 51 generated from the image generators 11, 13, and 15. Each of the image, the bottom image, and the side image is input and compared with the normal image mentioned to process whether the current state of the material 51 is good or bad. That is, the image processor 17 receives the upper image, the lower image and the side image of the material 51 for the current state generated from the image generators 11, 13, and 15 in real time, and inputs the input material 51. Is compared with the normal image for each of the upper image, the lower image and the side image in real time, and as a result of the mentioned comparison, whether the current state of the material 51 to be wound is good or bad. At this time, is the image processing unit 17 scratched on the surface of the material 51, is foreign material adsorbed on the material 51, is the pattern formed on the material 51 defective or is the material 51 bent? Defective elements such as whether the material 51 is folded can be confirmed. In addition, the image processing unit 17 can also check whether the material 51 is wound in the correct direction. That is, when the material 51 is wound in a direction that is out of the width direction, the material 51 is wound at an angle, so that the image for the width direction of each of the upper image and / or the lower image is clearly different from the normal image. This can be confirmed, and thus the material 51 can be inspected as to whether the winding is made in the correct direction. In addition, as will be described later, even when the material 51 is divided into at least two windings, the inspection may be performed even if the material 21 is correctly divided into at least two windings.

As such, the image processor 17 compares the normal image of each of the top image, the bottom image, and the side image of the material 51 with the generated image of each of the top image, the bottom image, and the side image of the material 51 in real time. By doing so, it is possible to handle whether the current state of the material is good or bad.

Here, the image processing unit 17 is a normal image for each of the upper image, the lower image and the side image of the material 51 mentioned above is inputted, and generated for each of the upper image, lower image and side image of the material 51 It may include an IC chip having a program that receives an image and compares it with each other.

The marking processing unit 19 may mark the defective portion of the material when the current state of the material 51 is defective. Thus, the marking processing unit 19 is connected to the image processing unit 17, and marks the defective portion of the material 51 when the current state of the material 51 is input as defective from the image processing unit 17. That is, the marking processing unit 19 determines that the current state of the material is defective from the image processing unit 17, and marks the defective area of the material 51 based on the result of receiving the defective part. Thus, the marking processing unit 19 may be formed of an inkjet printer or the like capable of spraying a member for marking together with a driving unit that can be driven. In addition, the marking processing unit 19 is preferably located at the rear end of the image generating units 11, 13, and 15 mainly based on the winding direction of the material 51. Moreover, also in the case of the marking processing part 19, it can also be located in the upper part, the lower part, and the side surface of the material 51, respectively.

In addition, the apparatus 100 for inspecting the wound material mentioned above may further include a display unit 23, a stop unit 25, an injection unit 21, and the like. The display unit 23 is connected to the image processing unit 17 to display data on whether the current state of the material 51 is good or bad, and may include a monitor or the like. The stopper 25 may be connected to the image processor 17 to stop the winding operation of the material 51 when the current state of the material 51 is input as defective. Here, the stopper 25 receives the current state of the material 51 from the image processing unit 17 in real time, and in particular, when the current state of the material 51 is input as bad, the winding of the material 51 is performed. By stopping the operation of the apparatus, an IC chip or the like having a built-in control program capable of interrupting the operation of the winding apparatus mainly between the image processing unit 17 and the winding apparatus may be included. In addition, the injection unit 21 may spray the cleaning gas toward the material 51 to remove the foreign matter adsorbed on the material 51 when the material 51 is wound. That is, if foreign matter that can be easily removed from the material 51 is adsorbed on the material 51, the foreign matter inspection device 100 of the wound material mentioned above is made to be defective if the foreign material is not removed. As it can be determined, even when the situation which can be easily solved in this way is judged to be defective, the injection unit 21 is provided because the efficiency of the inspection apparatus 100 of the wound material is lowered. In other words, the spraying unit 21 is provided to ensure the efficiency of the use of the inspecting apparatus 100 of the wound material, and the image generating unit 11, 13, 15 is used to Before the image is generated, foreign matter or the like that is removably adsorbed from the material 51 is removed in advance. Therefore, since the injection part 21 must inject the cleaning gas which does not affect the material 51, it mainly injects air or inert gas. In addition, the injection unit 21 is preferably installed at the front end of the image generating unit (11, 13, 15) on the basis of the winding direction of the material 51, to be installed on all of the upper, lower and side surfaces of the material 51 It may be.

Hereinafter, the inspection method of the winding material 51 using the inspection apparatus 100 of the mentioned winding material is demonstrated.

Winding is performed from the first roller 53 roller to the second roller 55 so that the material 51 can be used in a subsequent process. That is, since the material 51 wound up on the second roller 55 must be used in the subsequent process, the material 51 is wound from the first roller 53 to the second roller 55 as mentioned. In this case, when the material 51 is defective, the material 51 may be inspected using the inspection apparatus 100 because it may seriously affect the performance of subsequent processes.

First, the cleaning gas is injected to the material 51 which is wound up from the first roller 53 to the second roller 55 by using the injection part 21. At this time, the spraying of the cleaning gas may be performed on all of the upper, lower and side surfaces of the material 51. And foreign matter can be removed from the material 51 by spraying the cleaning gas. As described above, spraying the cleaning gas onto the material 51 by using the injection part 21 is to secure the efficiency of the inspection apparatus 100 by removing the foreign matter that can be easily removed from the material 51. That is, if the foreign matter that can be easily removed from the material 51 is not removed, the present state of the material 51 may be treated as defective even by the mentioned foreign matter, and as a result, the inspection apparatus 100 frequently processes the defect. This is because the efficiency can be reduced.

Each of the upper, lower, and side images of the material 51 on which the winding is made is generated by using the image generators 11, 13, and 15. That is, by using the upper image generating unit 11 to scan in the form of a line perpendicular to the direction in which the material 51 is wound, to generate an upper image of the material 51, the lower image generating unit 13 By scanning in the form of a line perpendicular to the direction in which the material 51 is wound, to generate a lower image of the material 51, and using the side image generation unit 15 and the thickness direction of the material 51 By scanning in the form of lines in the same direction, a side image of the material 51 is generated.

Subsequently, the top, bottom and side images of the material 51 for the current state generated in real time by the image generating units 11, 13, and 15 are input to the image processing unit 17. Accordingly, the image processing unit 17 may determine the upper, lower, and side images of the material 51 for the current state input from the image generating units 11, 13, and 15, and the material 51 for the normal state. The top, bottom and side images are compared with each other. That is, the image processor 17 compares the generated image and the normal image of the upper, lower, and side surfaces of the material 51 with each other.

In this way, as a result of comparing the generated image and the normal image of the upper, lower and side surfaces of the material 51 with each other using the image processing unit 17, it is processed whether the current state of the material 51 is good or bad. At this time, the display unit 23 displays in real time the data on whether the current state of the material 51 is good or bad so that the operator can check. And when the current state of the material 51 is treated as defective by the image processing unit 17, the image processing unit 17 provides a failure signal to the marking processing unit 19. At this time, the bad signal provides up to the position of the bad portion of the material 51. Thus, the marking processing unit 19 marks the defective portion of the material 51. In addition, when the current state of the material 51 is treated as defective by the image processing unit 17, it may also provide a failure signal to the interruption unit 25. Accordingly, the interruption unit 25 may be provided with a signal in which the current state is processed as defective by the image processing unit 17, and as a result, may stop the winding operation of the material 51.

As mentioned, the inspection apparatus 100 of the wound material of the present invention is a defect on the material 51 to be wound, that is, whether there is a scratch on the surface of the material 51, foreign matter is adsorbed on the material 51 Inspect whether there is a defect in the pattern formed on the material 51, whether the material 51 is bent, the material 51 is folded, and the like, and whether the material 51 is wound properly. Can be performed in real time. Thus, the inspection apparatus 100 of the winding material of the present invention can provide a more stable winding material 51 in the form of a film in a subsequent process, and also can perform the inspection of the winding material 51 in real time. The time according to the inspection of the winding material 51 can be shortened sufficiently.

And when winding a material from a 1st roller to a 2nd roller, a material can be split at least 2 times. Thus, the second roller is provided with at least two and winds up the material divided into at least two.

4 and 5 are diagrams for explaining examples of using the inspection apparatus of the wound material of Figure 1 when the wound material is divided into three.

4 and 5, the first roller 53 and the second roller 55 are divided into three by dividing the material 51 wound up from the first roller 53 to the second roller 55. It can achieve by providing the division part 41 which can divide | divide material 51 into three in between. Thus, three second rollers 55 are provided, and the materials 51a, 51b, 51c, which are divided into three by the division part 41 from the first roller 53, are wound on each of the three second rollers 55. can do.

Here, the inspection of the material 51 is performed before the three division using the inspection apparatus 100 of the wound material of the present invention, and the inspection of the materials 51a, 51b, 51c after the three division is performed. In this case, it is possible to check whether the current state of the material 51 is not only defective, but also whether the material 51 is accurately divided. That is, the material 51 is compared by comparing the width l1 of the material 51 before being divided into three and the widths l2, L3, and L4 for each of the materials 51a, 51b and 51c after being divided into three. It is possible to confirm whether 3 divisions are made correctly. In other words, the material 51 is compared by comparing the width L1 before the material 51 is divided into three and the value L2 + L3 + L4 obtained by adding the widths L2, L3, and L4 after the material is divided into three. ), You can see if it is divided correctly. In addition, it is possible to confirm whether the material 51 is accurately divided into three parts by whether the widths (l2, l3, and l4) for each of the materials 51a, 51b, and 51c after being divided into three parts coincide within the error range. have.

Thus, in the inspection apparatus 100 for wound material mentioned above, an image is provided when a division part 41 capable of dividing at least two materials 51 between the first roller 53 and the second roller 55 is provided. The generation units 11, 13, and 15 are provided at positions before the division of the material 51 and positions after the division of the material 51, and the image processing unit 17 is provided by the image generation units 11, 13, and 15. The division of the material 51 is performed accurately by comparing the width before the division of the material 51 with the width after the division of the material 51 as a result of scanning in the form of a line perpendicular to the direction in which the material 51 is wound. Can be processed.

In addition, as mentioned above, in the division of the material using the division part 41, a defect may occur in the side surface of the material 51. Therefore, when using the inspection apparatus 100 of the wound material according to the present invention, even the side surface of the material 51 can be inspected, so that even defects that may occur by dividing the material 51 by using the division part 41 are provided. It can be processed correctly.

Since the inspection apparatus for the winding material of the present invention can provide the winding material in the form of a film more stably in the subsequent process, the subsequent process can be performed more stably and the improvement of the reliability of the process can be expected. In addition, by performing the inspection on the wound material in real time, it is possible to sufficiently shorten the time required for the inspection of the wound material, so that the manufacturing process can be sufficiently shortened, and as a result, the competitiveness of shortening the manufacturing process can be secured.
