Description

[Technical Field]

[0001] The present invention relates to a ball tack test determination system, and more particularly to one that can automatically determine the test. [Background technology]

[0002] A conventional ball tack test evaluation system will be described using the measuring device shown in Figure 11 as an example. The measuring device for measuring the adhesive performance of adhesive tapes or labels includes an electric or pneumatic actuator that can be triggered manually or remotely to perform rolling ball tack evaluation under extreme conditions or conditions different from those standardized in an adhesive laboratory by utilizing a small laboratory oven or a small weathering test chamber to reproduce extreme conditions. The measuring device is installed in the chamber and remotely triggered through the actuator installed in the device. The trigger system includes a power supply that converts the high voltage of a standard laboratory power supply to low DC voltage to avoid the risk of electric shock during operation of the device, two separate metal cables for conducting voltage to the actuator's electric coil, an electronic control box that houses a momentary pushbutton switch, an actuator that houses an electric coil, a spring, and a metal movable piston, and a mechanical fixing system for attaching the actuator to the device and the piston to a mechanical ball release system. This system can then be remotely operated to trigger a system that releases a metal ball at the top of a lamp (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2018-500554 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned system has the following points that need to be improved. The above-mentioned system automatically releases the metal ball, which is one step in the test. However, the test results cannot be judged automatically, and as in the past, they must be judged by the user, which is another point that needs to be improved.

[0005] Furthermore, the above-mentioned system is applicable to the rolling ball tack test, which is a type of ball tack test, but not to the tilted ball tack test. The tilted ball tack test also requires a release step for the metal ball used as the test ball, so the above-mentioned system could be applied only to that step. However, the above-mentioned system still has an issue that needs improvement: it cannot automatically make a judgment in the tilted ball tack test.

[0006] Therefore, an object of the present invention is to provide a ball tack test judgment system that can automatically and objectively judge the ball tack test. [Effects of the Invention]

[0015] This allows the tilted ball tack test to be judged automatically and objectively.

[0016] In the ball tack test judgment system according to the present invention, the ball tack test judgment device judges whether the ball tack test has passed or failed using an image separated by a predetermined time from the test image.

[0017] This makes it easy to judge the tilt ball tack test.

[0021] This allows reflections on the surface of the test ball to be taken into account, allowing for more accurate judgment of the ball tack test.

[0022] In the ball tack test judgment device of the present invention, the ball tack test judgment unit is characterized in that it determines the position of the test ball by pattern matching processing using the test ball image against a predetermined image of the test image information.

[0023] This allows the ball tack test to be judged easily and quickly.

[0024] In the ball tack test judging device according to the present invention, the ball tack test judging section judges whether the ball tack test is passed or failed in an inclined ball tack test.

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. [Example]

[0032] The ball tack test determination system according to the present invention will be described using a ball tack test determination system 100 shown in FIG. 1 as an example.

[0033] 1. Configuration of Ball Tack Test Judgment System 100 The ball tack test determination system 100 is used for the tilting ball tack tester A. The tilting ball tack tester A is a tester used for the tilting ball tack test method.

[0034] 1. Inclined Ball Tack Tester A The inclined ball tack tester A is a testing machine used to evaluate the adhesive strength of adhesive thin materials (hereinafter referred to as adhesive thin materials), such as adhesive tapes and adhesive sheets, based on the inclined ball tack test method. The inclined ball tack test method involves rolling a test ball on an inclined plate and measuring the maximum size of the test ball that stops on the adhesive thin material being tested. The ball stops in a state determined by the test method, test equipment, etc., such as a state in which the test ball does not move for a specified period of time, for example, 5 seconds or more. The inclined ball tack test method using the inclined ball tack tester A is specified in the JIS standard (JIS Z0237).

[0035] The configuration of the tilting ball tack tester A will be explained using Figure 2. The tilting ball tack tester A has a fixed portion A101, a tilting portion A103, a gate portion A105, a test ball receiving portion A107, and a test ball A109. The fixed portion A101 has a predetermined weight and fixes the tilting ball tack tester A in a predetermined position so that it does not move. The tilting portion A103 has a predetermined inclined surface P103 on which the test ball A109 rolls. The inclined surface P103 has a test object placement area R103 where a thin adhesive substance, which is a test object T, is placed in a predetermined position.

[0036] The gate portion A105 has a test sphere mounting portion A105a, a rotation shaft portion A105b, a rotation operation portion A105c, a connecting portion A105d, and a rotation shaft support portion A105e. The test sphere mounting portion A105a holds the test sphere A109 before the start of the test. The test sphere mounting portion A105a has multiple recesses so that the test sphere A109 can be stably held. The rotation shaft portion A105b has a cylindrical shape. The rotation shaft portion A105b is connected to the test sphere mounting portion A105a. The rotation shaft portion A105b rotates the test sphere mounting portion A105a as it rotates around its own central axis J105b. The rotation operation portion A105c is located at one end of the rotation shaft portion A105b. The rotation of the rotation operation unit A105c rotates the rotation shaft unit A105b, which in turn rotates the test sphere mounting unit A105a. The connecting unit A105d connects and fixes the test sphere mounting unit A105a and the rotation shaft unit A105b. The connecting unit A105d rotates the test sphere mounting unit A105a in response to the rotation of the rotation shaft unit A105b caused by the rotation of the rotation operation unit A105c. The rotation shaft support unit A105e supports the rotation shaft unit A105b so that it can rotate around the central axis J105b. The rotation shaft support unit A105e is fixed to the inclined unit A103. As a result, the rotation shaft unit A105b, the connecting unit A105d, and the test sphere mounting unit A105a are positioned at the upper end of the inclined unit A103.

[0037] The gate A105 is in a closed state when the test sphere A109 placed on the test sphere placing portion A105a remains placed on the test sphere placing portion A105a and does not roll along the inclined surface P103 of the inclined portion A103. On the other hand, the gate A105 is in an open state when the test sphere A109 placed on the test sphere placing portion A105a cannot remain placed on the test sphere placing portion A105a and rolls along the inclined surface P103 of the inclined portion A103.

[0038] The test sphere receiving portion A107 is arranged along the lower edge of the inclined portion A103. The test sphere receiving portion A107 receives the test sphere A109 that rolls along the inclined surface P103 of the inclined portion A103. The test sphere receiving portion A107 is provided with a cushioning material to absorb the impact of the rolling test sphere A109.

[0039] The test ball A109 is a spherical object made of a specified metal. The test ball A109 is a metallic spherical object with a smooth surface. A plurality of test balls A109 of different sizes are used. The test ball A109 is specified in the JIS standard JIS Z0237 for the inclined ball tack tester A. JIS Z0237 specifies a plurality of test balls of different sizes.

[0040] 2. Ball Tack Test Judgment System 100 The configuration of the ball tack test determination system 100 will be described with reference to Fig. 1. The ball tack test determination system 100 includes an image acquisition device 101, a gate open / close state detection unit 103, and a ball tack test determination device 105.

[0041] The image acquisition device 101 acquires an image of a test object placement area R103 where the test object T is placed on the inclined portion A103 of the inclined ball tack tester A. As the image acquisition device 101, a video camera can be used.

[0042] The image acquisition device 101 is placed above the inclined surface P103 of the inclined portion A103 of the inclined ball tack tester A, at a position where it can acquire an image of the test object placement area R103, using a predetermined fixing device such as a tripod.

[0043] The gate open / close state detection unit 103 detects the open / close state of the gate A105 of the inclined ball tack tester A. A proximity sensor can be used as the gate open / close state detection unit 103. When a proximity sensor is used as the gate open / close state detection unit 103, for example, the gate open / close state detection unit 103 is placed near the connecting portion A105d of the gate A105. When the gate open / close state detection unit 103 changes from a state where it can detect the presence of the connecting portion A105d to a state where it cannot detect it during detection, it transmits gate open state information indicating that the gate A105 has entered an open state.

[0044] The ball tack test determination device 105 determines whether a tilted ball tack test for a predetermined test object is successful or not, using image information of the test object placement area R103 acquired by the image acquisition device 101. The hardware configuration of the ball tack test determination device 105 will be described with reference to FIG. 3. The ball tack test determination device 105 has a CPU 105a, memory 105b, storage 105c such as an HDD (Hard Disk Drive) or SSD (Solid State Drive), keyboard 105d, mouse 105e, display 105f, various media drives 105g, external input interface 105h, and power supply circuit 105i.

[0045] The CPU 105a performs processing based on the operating system (OS), tilt ball tack test program, and other applications stored in the storage 105c. The memory 105b provides a working area for the CPU 105a. The storage 105c records and stores the operating system (OS), tilt ball tack test judgment program, and other application programs. The storage 105c also records and stores various information required for the tilt ball tack test judgment program.

[0046] The keyboard 105d and mouse 105e accept commands from the outside. The display 105f displays images such as a user interface. The media drive 105g reads the tilt ball tack test judgment program from a predetermined medium 105p on which the tilt ball tack test judgment program is recorded, and also reads other application programs from other media, thereby reading data from various media. The external input interface 105h transmits and receives information to and from external devices such as the image acquisition device 101 and gate open / close state detection unit 103.

[0047] Second Operation of Ball Tack Test Judging Device 105 The operation of the ball tack test determining device 105 is described below.

[0048] 1. Advance preparation (1) Test ball image Here, we will explain the preparations required before using the ball tack test judgment device 105. As mentioned above, the test sphere A109 is a metallic spherical object with a smooth surface, which makes it easy for the test environment to be reflected on the surface of the sphere, i.e., reflections. For example, as shown in Figure 4, when the test sphere A109 is placed on a predetermined mounting surface PS under a predetermined test environment, the test environment of the test sphere A109 may be displayed on the surface of the test sphere A109 as, for example, a reflected image RL of the ceiling light, a reflected image RC of the ceiling, and a reflected image RW of the wall. In addition, a shadow SH of the test sphere A109 may be displayed on the mounting surface PS. Such a reflected image of the test sphere A109 varies depending on the type of fixtures and their arrangement in the test location. Furthermore, the appearance of the shadow also varies depending on the arrangement of lighting fixtures, the light intensity, and the light direction. Meanwhile, the ball tack test judgment device 105 determines the presence and position of the test ball A109 in the test object placement area R103 (see Figure 2) of the tilting ball tack tester A by pattern matching the image of the test ball with the image of the test ball. Therefore, in order to reduce the influence of the test environment on the judgment of the success or failure of the tilting ball tack test, a test ball image SF (see Figure 4), which is an image of the test ball A109 under the test environment, is prepared and stored in advance in the memory 105b of the ball tack test judgment device 105 as test ball image information in association with test ball identification information that identifies the test ball. Furthermore, after the ball tack test judgment system 100 is properly installed, the test ball image can be acquired by placing the test ball A109 in the test object placement area R103 of the inclined ball tack tester A, thereby obtaining a test ball image that can more effectively eliminate the influence of the test environment on the judgment by pattern matching.

[0049] 2. Ball tack test judgment process The ball tack test determination process executed by the ball tack test determination device 105 in accordance with the ball tack test determination program will be described with reference to the flowcharts shown in FIGS.

[0050] A user of the ball tack test judgment system 100 selects an adhesive thin object to be the test object T, and fixes the selected test object T in a predetermined manner in the test object placement area R103 of the ball tack test judgment device 105. The user inputs test object identification information that identifies the selected test object T, such as the product number, model number, and name, into the ball tack test judgment device 105.

[0051] As shown in FIG. 5, when the CPU 105a of the ball tack test determination device 105 acquires test object specifying information (S501), it stores and holds the acquired test ball specifying information in the memory 105b (S503).

[0052] The user also selects a test ball A109 to be used for a specific test object in the tilted ball tack test. The user inputs test ball identification information, such as the test ball number, that identifies the selected test ball A109 into the ball tack test judgment device 105.

[0053] When the CPU 105a acquires the test ball identification information (S505), it stores and holds the acquired test ball identification information in the memory 105b as test ball information (S507).

[0054] The user inputs test start information to indicate that a tilted ball tack test is about to begin, which starts the tilted ball tack test judgment process in the ball tack test judgment device 105. The user inputs the test start information, for example, by selecting the tilted ball tack test start button displayed on the display 105f using the keyboard 105d or the like.

[0055] When the CPU 105a receives the test start information (S509), it prepares to acquire images from the image acquisition device 101 via the external input interface 105h (S511).

[0056] The user places the selected test ball A109 in a predetermined position on the test ball mounting portion A105a of the tilting ball tack tester A. Then, at a predetermined timing, the user rotates the rotation operation portion A105c in a predetermined direction to rotate the test ball mounting portion A105a in the predetermined direction and open the gate portion A105.

[0057] When the gate open / close state detection unit 103 detects that the rotation of the rotation shaft portion A105b accompanying the rotation of the rotation operating portion A105c, and therefore the rotation of the connecting portion A105d, means that the connecting portion A105d is not in the predetermined position, that is, the test ball placing portion A105a has rotated and the gate portion A105 is in the open state, it transmits gate open state information.

[0058] When the CPU 105a acquires gate open state information from the gate open / close state detection unit 103 (S513), it starts acquiring images relating to the test object placement area R103 from the image acquisition device 101 (S515). After a predetermined time has elapsed (S517), the CPU 105a ends image acquisition from the image acquisition device 101 (S519) and stores and holds the acquired image information in the memory 105b as test image information (S521).

[0059] The test image information is a series of images captured at a predetermined frame rate, and at least each frame of the test image information is associated with an image corresponding to the frame and a capture time.

[0060] 6, the CPU 105a acquires, from the test ball image information, a test ball image corresponding to the test ball identification information saved in step S507 (see FIG. 5) as a test ball image to be used (S601). The CPU 105a also acquires, from the stored test image information, a predetermined image, for example, an image corresponding to the last frame, as a first matching target image (S603).

[0061] The CPU 105a executes a pattern matching process using the used test ball image on the first matching target image (S605). The pattern matching process, for example, sequentially scans the area of ​​the first matching target image that corresponds to the used test ball image, determines the degree of similarity with the used test ball image, and determines that the test ball is included if the degree of similarity is equal to or greater than a predetermined value.

[0062] The CPU 105a determines whether or not the test ball is captured in the first matching target image (S607). If the CPU 105a determines that the test ball is captured in the first matching target image, it determines the position of the test ball in the first matching target image (S609). The CPU 105a stores and holds the determined position of the test ball in the first matching target image as first test ball position information in the memory 105b (S611).

[0063] The CPU 105a acquires, as the second matching target image, a one-frame image corresponding to the stillness holding time before, for example, 5 seconds before, the photographing time of the first matching target image in the test image information (S613). The stillness holding time is set to a time that satisfies the stillness state required in the tilted ball tack test.

[0064] The CPU 105a executes pattern matching processing on the second matching target image using the used test ball image (S615). The pattern matching processing on the second matching target image is the same as the pattern matching processing on the first matching target image. The CPU 105a determines whether a test ball is captured in the second matching target image (S617). If the CPU 105a determines that a test ball is captured in the second matching target image, it determines the position of the test ball in the second matching target image (S619). The CPU 105a stores and retains the determined position of the test ball in the second matching target image as second test ball position information in the memory 105b (S621).

[0065] 7, the CPU 105a determines whether the position indicated by the first test ball position information can be considered the same as the position indicated by the second test ball position information (S701). If the CPU 105a determines that the position indicated by the first test ball position information can be considered the same as the position indicated by the second test ball position information, it determines that the test subject's holding time of the test ball is at least longer than the stationary holding time required to pass the test, and determines the test subject's test result for the tilted ball tack test using the test ball A109 as "pass" (S703). For example, if the test ball A109 is stopped at the position shown in FIG. 8A when the first matching target image is captured, and the test ball A109 is stopped at the position shown in FIG. 8B when the second matching target image is captured, the test result is determined to be "pass."

[0066] On the other hand, if the CPU 105a determines that the position indicated by the first test ball position information cannot be considered to be the same as the position indicated by the second test ball position information, it determines that the test subject's holding time of the test ball is shorter than the stationary holding time required to pass the test, and determines the test result of the test subject for the tilted ball tack test using the test ball A109 to be "fail" (S705). For example, if the test ball A109 is stopped at the position shown in Figure 8A when the first matching target image is captured, and the test ball A109 is stopped at the position shown in Figure 9A when the second matching target image is captured, the test result will be determined to be "fail."

[0067] Using the test results of steps S703 and S705, the CPU 105a generates test result information that associates test object identification information, test ball information, and test results (S707). The CPU 105a uses the generated test result information to display the test results of the tilted ball tack test using the test balls for the test object on the display 105f (S709). For example, as shown in FIG. 10A, the CPU 105a uses the test result information generated in step S707 to display the test object, the test balls used, and the test results. Additionally or alternatively, as shown in FIG. 10B, the CPU 105a uses the test result information generated in step S707 to display the test balls used and test results for tests previously conducted on the test object. This allows the user to easily check the maximum used ball that passed the tilted ball tack test for the test object.

[0068] If the CPU 105a determines in step S613 (see FIG. 6) that the test ball is not in the first matching target image, it determines that the test object does not have the adhesive strength to keep the test ball in place, and judges the test result to be a failure (S705: see FIG. 7), and continues the subsequent processing.

[0069] Furthermore, if the CPU 105a determines in step S617 (see FIG. 6) that the test ball is not captured in the second matching target image, it determines that the test subject's holding time for the test ball is shorter than the stationary holding time required to pass the test, determines the test result as fail (S705: see FIG. 7), and continues the subsequent processing. For example, if the test ball A109 is captured stopped at the position shown in FIG. 8A when the first matching target image is captured, and the test ball A109 is captured stopped at the position shown in FIG. 9B when the second matching target image is captured, that is, if the used test ball A109 is not captured in the second matching target image, the test result will be determined as "fail."

[0070] 7, the user changes the test object and / or the test ball to be used, if necessary, and performs the next tilted ball tack test. The CPU 105a repeats the processes of steps S501 (see FIG. 5) to S709 until the tilted ball tack test is completed (S711).

[0071] In this way, the ball tack test judgment system 100 can use an image of the test object placement area R103 of the tilted ball tack tester A to easily and objectively determine whether the test object passes or fails the tilted ball tack test.

[0072] [Other embodiments] (1) Pattern matching process: In the first embodiment described above, whether or not a test ball is captured in the first and second matching target images is determined by pattern matching using the test ball image, but any method can be used as long as it can determine whether or not a test ball is captured. For example, whether or not a test ball is captured may be determined by whether or not an edge corresponding to the test ball can be extracted by edge extraction process on the first and second matching target images.

[0073] (2) Use of characteristics of the test object: In the above-described first embodiment, characteristics of the test object T may be further used to determine whether or not a test ball appears in the first matching object image and the second matching object image. For example, the color of the surface of the test object, whether it is glossy, transparent, etc. may be taken into consideration to determine whether or not a test ball appears in the first matching object image and the second matching object image. In this case, the similarity in the pattern matching process may be adjusted, for example, to set a higher similarity if the test object is whitish, or a lower similarity if the test object is transparent.

[0074] (3) Test Ball Image: In the first embodiment, an image of a test ball captured in a test environment was used as the test ball image, but any image representing a test ball may be used. For example, a 3D test ball model may be created using computer graphics, the test environment may be rendered on the surface of the 3D test ball model, and a 2D image of the 3D test ball model may be captured and used as the test ball image.

[0075] (4) Hardware Configuration of Ball Tack Test Determination Device 105: In the above-described first embodiment, the ball tack test determination device 105 is formed using a CPU 105a, etc. However, it is not limited to the illustrated example as long as it can execute the various processes according to the present invention. For example, it is also possible to execute the various processes using a dedicated logic circuit.

[0076] (5) Image Acquisition Device 101: In the first embodiment, a video camera is used as the image acquisition device 101, but the image acquisition device 101 is not limited to the example shown, as long as it can acquire a series of images.
