Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to an adhesion testing device. Background Technology

[0002] Ink adhesion refers to the ability of ink to adhere to a substrate, and it is closely related to the viscosity of the ink. This adhesion is achieved through physical and chemical processes, enabling the ink to firmly adhere to the printing substrate.

[0003] To avoid issues such as back-sticking and scratches during subsequent processing and to ensure the integrity of the printed pattern, it is necessary to test the adhesion of the inks printed on the packaging during the packaging production process, so as to make targeted adjustments to the process and equipment.

[0004] One related technology proposes an adhesion testing device that uses an adhesive applicator to stick adhesive tape to the ink-printed area on the surface of a packaging sample, and then uses a tearing device to pull the tape off at a uniform speed. The adhesion of the ink is tested by examining the degree of damage to the ink.

[0005] The aforementioned adhesion testing equipment uses positioning components to fix the packaged samples. When testing different parallel samples in the same batch, each sample needs to be tested individually, resulting in low testing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an adhesion testing device to solve the problem of low adhesion testing efficiency.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] An adhesion testing device includes a platform, a robotic arm, an image acquisition unit, an adhesive applicator, and an adhesive peeler. The platform includes a first driving component, a placement seat, and a fixing assembly. The first driving component is connected to the placement seat to drive the placement seat to move along a first direction. At least two sets of the fixing assemblies are spaced apart on the placement seat along the first direction, and the fixing assemblies are used to fix the sample to be tested on the placement seat. The robotic arm and the image acquisition unit are respectively disposed on two opposite sides of the placement seat along a second direction. The adhesive applicator and the adhesive peeler are both disposed at the end of the robotic arm. The adhesive applicator is used to apply adhesive tape of a preset length to the sample to be tested, and the adhesive peeler is used to peel the adhesive tape off the sample to be tested. The second direction and the first direction are mutually perpendicular horizontal directions.

[0009] In one embodiment, the platform further includes a base, and the shelf is slidably disposed on the base.

[0010] In one embodiment, the first drive unit is connected to the storage seat via a lead screw module.

[0011] In one embodiment, the fixing component is a quick clamp.

[0012] In one embodiment, the fixing component and the robotic arm are located on the same side of the storage seat.

[0013] In one embodiment, the adhesive-tearing machine includes a second drive member, a first clamping plate and a second clamping plate hinged to each other, one end of the second drive member being hinged to the first clamping plate and the other end being hinged to the second clamping plate, so that the first clamping plate and the second clamping plate move closer to or further away from each other.

[0014] In one embodiment, the adhesive applicator includes a pressure roller for rolling the adhesive tape.

[0015] In one embodiment, the image acquisition device includes an industrial camera, which is tilted downwards.

[0016] In one embodiment, the image acquisition device further includes a camera bracket on which the industrial camera is adjustable in angle and height.

[0017] In one embodiment, the adhesion detection device further includes a control system and an alarm light. The control system is communicatively connected to the platform, the robotic arm, the adhesive applicator, the adhesive peeler, the image acquisition unit, and the alarm light.

[0018] The beneficial effects of this utility model are as follows: The adhesion testing device of this utility model uses a first driving component to drive the placement seat, so that the placement seat can move relative to the robotic arm along a first direction, thereby moving the test samples fixed to different fixing components to the positions of the adhesive applicator and the adhesive peeler for adhesive application and peeling. During the testing of the previous test sample, another test sample can be fixed to another fixing component, saving the time of removing the already tested test sample from the fixing component and replacing it with a new test sample, thus improving the testing efficiency.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] refer to Figures 1-3As shown, an adhesion testing device is proposed in an embodiment of this utility model, including a platform, an adhesive applicator 5, an adhesive peeler, a robotic arm 4, and an image acquisition unit. The platform includes a first driving component 2, a placement seat 1, and a fixing assembly 3. The first driving component 2 is connected to the placement seat 1 and is used to drive the placement seat 1 along a first direction (…). Figure 1 The sample is moved along the X-axis, and at least two sets of fixing components 3 are spaced apart on the base 1 along the first direction. The fixing components 3 are used to fix the sample to be tested on the base 1. The robotic arm 4 and the image acquisition device are respectively set on the base 1 along the second direction. Figure 1 On opposite sides (in the Y direction), the adhesive applicator 5 and the adhesive peeler are both located at the ends of the robotic arm 4. The adhesive applicator 5 is used to apply tape of a preset length to the sample to be tested, and the adhesive peeler is used to peel the tape off the sample. The robotic arm 4 can perform movements including extension, rotation, lifting, or swinging up and down to ensure that the tape on the adhesive applicator 5 is accurately applied to the target position. The robotic arm 4 is prior art and will not be described in detail here. The image acquisition unit is used to acquire image information of the sample to be tested, and the second direction and the first direction are mutually perpendicular horizontal directions.

[0029] The aforementioned adhesion testing device utilizes the first driving component 2 to drive the placement seat 1, enabling the placement seat 1 to move relative to the robotic arm 4 along a first direction. This allows the test samples fixed to different fixing components 3 to be moved to the positions of the adhesive applicator 5 and the adhesive peeler, respectively, for adhesive application and peeling. During the testing process, while the previous test sample is being applied and peeled, another test sample can be fixed to another fixing component 3, eliminating the time required to remove the already tested test sample from the fixing component 3 and replace it with a new test sample, thus improving testing efficiency. It is understandable that after the tape is applied to the test sample, it needs to be held for a certain period of time before being peeled off to allow the tape to fully adhere to the ink. Therefore, the movement of the placement seat 1 can switch the test samples located below the adhesive applicator 5, allowing the tape to be applied to other test samples, thus eliminating the time required for the tape to fully adhere to the ink and saving testing time.

[0030] In one embodiment, the stage further includes a base 11, on which a robotic arm 4 is mounted. The base 11 is also provided with a slide rail extending along a first direction. The placement seat 1 is slidably mounted on the slide rail to improve the stability of the placement seat 1's movement along the first direction. Specifically, two slide rails are spaced apart along a second direction, and the placement seat 1 is slidably mounted on the two slide rails on opposite sides along the second direction to further improve the movement stability of the placement seat 1. In one embodiment, the first driving component 2 is a motor used in conjunction with a lead screw module, and the placement seat 1 is mounted on the sliding nut of the lead screw module. The lead screw module has a self-locking function, which reduces the possibility of displacement of the sample along the first direction when adhesive is applied to the sample, thus improving the detection accuracy.

[0031] In one embodiment, the fixing component 3 employs a quick-release clamp to further improve the sample loading and unloading efficiency, thereby increasing the detection efficiency. Specifically, the quick-release clamp uses a pneumatic clamp to achieve automatic clamping and releasing, reducing labor costs.

[0032] It is worth emphasizing that, to avoid interference from the fixed component 3 in acquiring image information of the sample under test, the fixed component 3 and the robotic arm 4 are positioned on the same side, that is, the fixed component 3 and the image acquisition component are respectively positioned on opposite sides of the placement base 1 along the second direction. Furthermore, to prevent the sample under test from arching during adhesive application by the adhesive applicator 5, the adhesive applicator 5 applies adhesive in the direction away from the fixed component 3 along the second direction, and the adhesive peeler also peels adhesive in the direction away from the fixed component 3 along the second direction. The adhesive applicator 5 is existing technology and can be any adhesive applicator 5 with specific adhesive supply, application, and cutting functions; details will not be elaborated here. Preferably, the adhesive applicator 5 includes a pressure roller, which is used to roll the adhesive tape during application to reduce the possibility of air bubbles during the application process, thereby improving detection accuracy.

[0033] The tape-tearing machine includes a second drive unit, a first clamping plate and a second clamping plate that are hinged to each other. One end of the second drive unit is hinged to the first clamping plate and the other end is hinged to the second clamping plate. When tearing the tape, the second drive unit drives the first clamping plate and the second clamping plate to move closer to each other to clamp the tape. Then, under the drive of the robotic arm 4, the tape is torn off at a uniform speed.

[0034] In one embodiment, the adhesion detection device further includes a control system 8. The control system 8 is communicatively connected to the image acquisition unit, the platform, the robotic arm 4, the adhesive applicator 5, the adhesive peeler, and the fixing component 3. The control system 8 can control the actions of the robotic arm 4, the adhesive applicator 5, the adhesive peeler, and the fixing component 3 and receive electrical signals transmitted by the image acquisition unit to achieve automated detection and reduce labor costs.

[0035] Based on the configuration of the control system 8, the adhesion detection device also includes an alarm light 9 and an interactive panel 10. The alarm light 9 is also communicatively connected to the control system 8 to issue a warning signal when an abnormality occurs in the adhesion detection device, such as when the robotic arm 4 fails to perform a preset action. The interactive panel 10 is used to interact with the control system 8 to control the control system 8. The control principle and control structure of the control system 8 for the above-mentioned components, as well as the interaction between the interactive panel 10 and the control system 8, are all prior art and will not be described in detail here.

[0036] For example, the image acquisition device includes an industrial camera 6, which is tilted downwards to better acquire image information of the sample under test. More specifically, the image acquisition device also includes a camera bracket 7 for supporting the industrial camera 6. The height and angle of the industrial camera 6 on the camera bracket 7 are adjustable to accommodate samples of different thicknesses or sizes. For instance, the industrial camera 6 is fixed to the camera bracket 7 by a mounting base, and one of the mounting base and the camera bracket 7 has a third-direction ( Figure 1 A first mounting hole extends in a strip shape (Z-direction), and a second mounting hole is provided on the other side, forming a circular shape. The mounting base and camera bracket 7 are fixedly connected by fastening bolts passing through the first and second mounting holes. By adjusting the position of the fastening bolts in the first mounting hole, the height between the mounting base and camera bracket 7 can be adjusted, thereby adjusting the height between the industrial camera 6 and camera bracket 7. Simultaneously, the industrial camera 6 is hinged to the mounting base, which has a vertically arranged adjusting bolt threaded onto it. The adjusting bolt abuts against the bottom surface of the mounting base. By adjusting the height of the adjusting bolt on the mounting base, the angle of the industrial camera 6 relative to the mounting base can be adjusted, thereby adjusting the angle of the industrial camera 6 relative to the camera bracket 7. The third direction is a vertical direction perpendicular to the first and second directions.

[0037] The adhesion testing process is briefly described below.

[0038] S1. Take the sample to be tested and place it on a flat base 1, then fix it with the fixing component 3. Specifically, when placing the sample to be tested on the base 1, the samples can be uniformly cut to ensure consistent size. The different samples to be tested can be fixed uniformly before applying the adhesive tape, or one sample can be fixed first, and then fixed one by one when applying or removing the adhesive tape to that sample.

[0039] S2: Apply the tape to the surface of the sample to be tested (the part printed with patterns, words, etc.). During the application process, the tape applicator 5 determines the tape application length and the position to cut the tape according to the parameters set by the control system 8.

[0040] S3: Apply pressure at a constant speed 5 to 10 times on the pressure roller on the adhesive applicator 5 until the air bubbles basically disappear.

[0041] S4: The stopwatch records the time. After 3 minutes, the tape-tearing machine smoothly and slowly tears off the tape and acquires image information of the sample under test through the image acquisition device. The control system 8 judges the ink adhesion by comparing the image information of the standard sample in the database with the acquired image information. The standard sample refers to a sample with intact ink.

[0042] When the stopwatch is recording time, the base 1 can be moved along the first direction so that the next sample to be tested is facing the adhesive applicator 5, and operations S2 and S3 can be performed again. Alternatively, any sample to be tested can be processed one by one through steps S2, S3, and S4, while other samples to be tested are fixed in place during this period to improve testing efficiency.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
