Marking durability testing device and method

Abstract

The present application discloses a device and method for testing the durability of a mark. At the driving mechanism end, a timing motor drives a rotating disc to rotate, and the bearing that rotates with the rotating disc drives a driving rod to perform horizontal reciprocating motion through a slideway. The wiping member in the wiping mechanism is driven by the driving rod to perform reciprocating wiping motion in the horizontal direction to wipe the mark on the surface of the test sample located below the wiping member, and perform a durability test on the mark. At the same time, the pressure regulating mechanism detects the test pressure applied by the wiping member to the surface of the test sample in real time and adjusts it to a preset test pressure when the pressure requirements are not met, so as to accurately control the test pressure. In this way, the mark can be automatically tested through the driving mechanism, the wiping mechanism and the pressure regulating mechanism, and the test speed, test time and test pressure can be accurately controlled to ensure the accuracy of the test results of the mark durability.

Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a marking durability testing device and method. Background Art

[0002] Many products are affixed with nameplates after production to provide users with information such as manufacturer trademark identification, brand differentiation, and product specifications. To ensure the durability of the nameplate, it is necessary to conduct durability testing on the nameplate. Durability includes both endurance and wear resistance.

[0003] The current testing method involves a tester wiping the marking with a gauze soaked in water or hexane, with the test time manually controlled by a stopwatch. However, manual testing methods cannot precisely control the wiping time and speed, resulting in inaccurate test results. Summary of the Invention

[0004] The present application provides a marking durability testing device and method to solve the problem that the test time and wiping speed of the manual testing method cannot be precisely controlled, resulting in inaccurate test results.

[0005] In the first aspect, the present application provides a marking durability testing device, comprising: a driving mechanism, the driving mechanism comprising: a fixed bracket, a driving rod, a timing motor, a rotating disc, a bearing and a slide; a first limiting ring and a second limiting ring are provided on the fixed bracket in the horizontal direction; the rotating shaft of the timing motor passes through the fixed bracket and is connected to the rotating disc, and the timing motor is used to drive the rotating disc to rotate according to a preset test time and a preset test speed; the bearing is fixed on the rotating disc, and the slide is sleeved on the outside of the bearing, and the bearing is used to rotate with the rotation of the rotating disc and drive the slide to move; one end of the driving rod The drive rod is connected to the slide, and the other end of the drive rod passes through the first limiting ring and the second limiting ring. The drive rod is driven by the slide and reciprocates in the horizontal direction along the fixed bracket. The wiping mechanism is connected to the driving mechanism, and the wiping mechanism includes a wiping member and a prototype groove. One end of the wiping member is connected to the end of the drive rod away from the slide. The prototype groove is located below the wiping member, and the prototype groove is used to place the test prototype. The other end of the wiping member abuts against the mark on the surface of the test prototype. The wiping member is used to follow the drive rod and perform a reciprocating wiping motion on the surface of the test prototype to test the durability of the mark on the surface of the test prototype. In this way, the mark can be automatically tested by the driving mechanism and the wiping mechanism. By adjusting the speed of the timing motor, the speed of the reciprocating wiping action can be achieved, and the wiping speed can be accurately controlled. By setting the running time of the timing motor, the test time can be accurately controlled. In this way, the test results of the durability of the mark can be guaranteed to be accurate.

[0006] In some embodiments of the present application, the marking durability testing apparatus further includes a pressure regulating mechanism for adjusting the pressure applied by the wiper to the surface of the test sample. This ensures that the wiper can maintain a constant force while performing the durability test on the marking on the surface of the test sample.

[0007] In some embodiments of the present application, the pressure adjustment mechanism includes a lifting platform, a stepper motor, and a pressure sensor; the lifting platform is located below the wiping mechanism, the lifting platform is connected to the stepper motor, and the prototype tank is placed on the lifting platform; the pressure sensor is connected to the end of the drive rod away from the slideway through a sensor fixing ring, and the wiping member is fixed to the lower end of the pressure sensor. The pressure sensor is used to detect the test pressure applied by the wiping member to the test prototype in the prototype tank. When the test pressure does not meet the preset test pressure, the lifting platform is controlled to rise or fall by the stepper motor to adjust the pressure applied by the wiping member to the test prototype. In this way, the marking durability test equipment can also accurately control the wiping force (test pressure) through the pressure adjustment mechanism.

[0008] In some embodiments of the present application, the marker durability testing device further includes a main control system, which is connected to the timing motor, the stepping motor, and the pressure sensor. The main control system is used to drive the timing motor and, based on a comparison between the test pressure detected by the pressure sensor and a preset test pressure, to drive the stepping motor. In this way, the main control system precisely controls the preset test time, preset test speed, and preset test pressure, ensuring accurate test results.

[0009] In some embodiments of the present application, the fixed bracket includes a base, a vertical bracket, and a horizontal bracket; the vertical bracket is fixed to the base, with the length of the vertical bracket perpendicular to the surface of the base; the horizontal bracket is fixed to the end of the vertical bracket away from the base, with the length of the horizontal bracket perpendicular to the length of the vertical bracket; a through-hole is provided at the connection between the horizontal bracket and the vertical bracket, through which the shaft of the timing motor passes to connect to the rotating disk. In this way, the fixed bracket supports the various components of the drive mechanism, so that the height of the various components of the drive mechanism can be adapted to the height of the wiping mechanism, ensuring that the drive rod can reciprocate in the horizontal direction, thereby allowing the wiping member to rub the marking on the surface of the test sample in the horizontal direction.

[0010] In some embodiments of the present application, the slide includes a slide body and a fixed end, the fixed end being used to secure a drive rod. The slide body has a through hole, through which the slide body is sleeved onto the outside of a bearing. The bearing generates a driving force on the slide body by driving a rotating disc with a timing motor. In this way, the driving force of the timing motor on the rotating disc is transmitted to the drive rod via the slide, thereby driving the drive rod to reciprocate horizontally.

[0011] In some embodiments of the present application, the through-hole is an elliptical hole, with the long axis of the through-hole perpendicular to the horizontal direction of the drive rod. This ensures that as the bearing rotates with the rotating disk, the through-hole accommodates the longitudinal displacement of the bearing, preventing the bearing from getting stuck in the through-hole and affecting the reciprocating motion of the drive rod.

[0012] In some embodiments of the present application, a first limiting ring and a second limiting ring are spaced apart and arranged at the same end of the horizontal bracket in the horizontal direction; the fixed end includes a first fixed end, the first fixed end is located on one side of the slide body, and the line connecting the first fixed end, the first limiting ring, and the second limiting ring is horizontal; the driving rod includes a first driving rod, one end of the first driving rod is connected to the first fixed end of the slide, and the other end of the first driving rod passes through the second limiting ring and the first limiting ring in sequence and is connected to the wiping mechanism. In this way, a driving mechanism with a single driving rod is formed, and the reciprocating motion of the single driving rod is used to drive the operation of the wiping mechanism.

[0013] In some embodiments of the present application, the first limiting ring and the second limiting ring are respectively arranged at opposite ends of the horizontal bracket in the horizontal direction; the fixed end includes a first fixed end and a second fixed end, and the first fixed end and the second fixed end are respectively located on opposite sides of the slide body, and the line connecting the first fixed end, the second fixed end, the first limiting ring and the second limiting ring is in a horizontal state; the driving rod includes a first driving rod and a second driving rod, one end of the first driving rod is connected to the first fixed end of the slide, and the other end of the first driving rod passes through the first limiting ring and is connected to the wiping mechanism; one end of the second driving rod is connected to the second fixed end of the slide, and the other end of the second driving rod passes through the second limiting ring; the first driving rod and the second driving rod are in a horizontal state. In this way, a driving mechanism with two driving rods is formed, and the two driving rods are still in a horizontal state through the bearings, and the reciprocating motion of the two driving rods is used to drive the operation of the wiping mechanism.

[0014] In some embodiments of the present application, the drive mechanism further includes a motor base, which is disposed above the base and on which the timing motor is placed. In this way, the motor base provides stability support for the timing motor, thereby ensuring the stability of the marker durability test.

[0015] In some embodiments of the present application, the bearing is located at a non-center position of the rotating disk. In this way, it is ensured that the bearing can generate a driving force on the slide when rotating with the rotating disk, thereby driving the drive rod to reciprocate.

[0016] In some embodiments of the present application, the prototype slot includes a fixed end and a movable end. The fixed and movable ends are connected by a telescopic member, which is used to adjust the size of the prototype slot formed by the fixed and movable ends to accommodate test prototypes of different sizes. In this way, the different-sized prototype slots can hold test prototypes of different sizes, ensuring that the test prototypes will not be displaced by the test pressure applied by the wiper during the test process, thereby ensuring the accuracy of the test results.

[0017] In the second aspect, the present application also provides a method for testing the durability of a logo, which is applied to the logo durability testing equipment described in the first aspect, and the method includes: starting the timing motor in the logo durability testing equipment, the timing motor drives the rotating disc to rotate according to the preset test time and the preset test speed, and the bearing on the rotating rotating disc drives the driving rod to reciprocate in the horizontal direction through the slide, so as to drive the wiping piece at one end of the driving rod to perform a reciprocating wiping action on the surface of the test sample; obtaining the test pressure applied by the wiping piece to the surface of the test sample detected by the pressure sensor in the logo durability testing equipment; if the test pressure does not meet the preset test pressure, controlling the stepper motor to adjust the setting height of the lifting platform located under the test sample to adjust the test pressure applied by the wiping piece to the surface of the test sample; after the pressure sensor detects that the adjusted test pressure meets the preset test pressure, stopping the stepper motor; when the test time meets the preset test time, stopping the timing motor and the test ends. In this way, the method can automatically test the label, and during the test process, parameters such as wiping time (test time), wiping force (test pressure) and wiping speed (test rotation speed) can be precisely controlled to ensure accurate test results of label durability.

[0018] In some embodiments of the present application, controlling a stepper motor to adjust the height of a lift platform located below a test prototype includes: if the test pressure is lower than a preset test pressure, activating the stepper motor to drive the lift platform upward to increase the test pressure to meet the preset test pressure; if the test pressure is higher than the preset test pressure, activating the stepper motor to drive the lift platform downward to reduce the test pressure to meet the preset test pressure. In this way, based on the relationship between the real-time detected test pressure and the preset test pressure, the stepper motor can accurately determine whether to drive the lift platform upward or downward, so that the adjusted test pressure can meet the preset test pressure requirement.

[0030] The following will clearly describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making any creative work are all within the scope of protection of this application.

[0031] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0032] In addition, in this application, directional terms such as "upper", "lower", "top", and "bottom" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative descriptions and clarifications, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0033] The product described in the embodiments of the present application may be an electronic device, including but not limited to a mobile phone, a notebook computer, a tablet computer, a laptop computer, a personal digital assistant or a wearable device.

[0034] Electronic devices are affixed with nameplates (hereinafter referred to as "labels") on the front or back to provide users with information such as manufacturer trademark identification, brand differentiation, and product specifications. To ensure the durability of the label during use and that its content is clear and easily identifiable, the label is subject to durability testing. Durability includes both endurance and wear resistance.

[0035] During the mark test, a force of 5N±1N is required to wipe the mark for 15 seconds, with one reciprocating motion per second. However, the existing test method requires the tester to hold a gauze soaked in water / n-hexane, etc. and repeatedly wipe the mark for testing. During the manual test method, the wiping force and wiping speed cannot be precisely controlled, and basically rely on the tester's experience. In addition, the wiping time is manually controlled by a stopwatch, and the test time cannot be precisely controlled. If the test fails, the manual test process is difficult to reproduce, resulting in inaccurate test results. In addition, the test process requires the use of an organic solution such as n-hexane, which is toxic to a certain extent. This test method requires the tester to be exposed to such toxic solutions for a long time.

[0036] An embodiment of the present application provides a label durability testing device that can perform automated testing on labels, and during the test process, parameters such as wiping time (test time), wiping force (test pressure) and wiping speed (test rotation speed) can be precisely controlled to ensure that the test results of label durability are accurate.

[0037] Figure 1 This is a structural diagram of the first type of identification durability testing equipment provided in an embodiment of the present application. Figure 2 This is a three-dimensional diagram of the first type of marking durability testing equipment provided in an embodiment of the present application.

[0038] like Figure 1 and Figure 2As shown, in some embodiments, a label durability testing device may include a drive mechanism 10 and a wiping mechanism 20. The drive mechanism 10 and the wiping mechanism 20 are adjacent to each other. The drive mechanism 10 is used to drive the wiping mechanism 20 to perform a durability test on a label on a test sample 30. The test sample 30 may be an electronic device such as a mobile phone or tablet.

[0039] The driving mechanism 10 may include at least one of: a fixed bracket, a driving rod, a timing motor 101, a rotating disc 102, a bearing 103 and a slide 104. The fixed bracket is used to support the various components of the driving mechanism 10; the timing motor 101 is used to provide driving force for the driving mechanism 10. The timing motor 101 can stop at a preset test time to achieve precise control of the wiping time; the timing motor 101 can also run at a preset test speed to achieve precise control of the wiping speed. The slide 104, the rotating disc 102 and the bearing 103 jointly drive the driving rod to move based on the driving force of the timing motor 101; the driving rod is used to drive the wiping mechanism 20 to move.

[0040] The fixed bracket can adopt an "L"-shaped structure consisting of two plates, or a "earth"-shaped structure consisting of three plates ( Figure 1 The structure shown in ) or the "I"-shaped structure ( Figure 2 The fixed bracket may also adopt other shapes as long as it can support the various components of the drive mechanism 10. Taking the fixed bracket with a "earth" shape as an example, the fixed bracket may include a base 1061, a vertical bracket 1062, and a horizontal bracket 1063.

[0041] Base 1061 is positioned on the ground or other stable, flat surface. Vertical bracket 1062 is secured to base 1061, with its length perpendicular to the surface of base 1061. Horizontal bracket 1063 is secured to the end of vertical bracket 1062 away from base 1061. Vertical bracket 1062 is used to adjust the height of horizontal bracket 1063 relative to base 1061, which can be determined based on the height at which wiping mechanism 20 is installed. The length of horizontal bracket 1063 is perpendicular to that of vertical bracket 1062; that is, horizontal bracket 1063 is horizontal and parallel to base 1061.

[0042] The fixed bracket is provided with a first limiting ring 1051 and a second limiting ring 1052 in the horizontal direction. For example, the limiting rings can be installed on a horizontal bracket 1063 at a certain height above the ground. The first limiting ring 1051 and the second limiting ring 1052 are used to limit the driving rod to ensure that the driving rod can reciprocate in the horizontal direction on the fixed bracket.

[0043] The rotating shaft 1011 of the timing motor 101 passes through the fixed bracket and is connected to the rotating disc 102. When the fixed bracket adopts a "earth"-shaped structure, a through-hole (not shown in the figure) is provided at the connection between the horizontal bracket 1063 and the vertical bracket 1062, and the rotating shaft 1011 of the timing motor 101 passes through the through-hole and is connected to the rotating disc 102.

[0044] The timing motor 101 is used to drive the rotating disc 102 to rotate according to a preset test time and a preset test speed. The driving direction of the timing motor 101 can be clockwise or counterclockwise. The preset test time is used to determine the wiping time of the wiping mechanism 20, and the preset test speed is used to determine the wiping speed of the wiping mechanism 20. The preset test time and the preset test speed are both test parameters to ensure the accuracy of the test results. They can be set in advance or set and changed in real time. For example, the preset test speed of the timing motor 101 can be 20-100 r / min, and the preset test time of the timing motor can be 0-30 min.

[0045] The drive mechanism 10 may further include a motor base 1012, which is disposed above the base 1061, and the timing motor 101 is placed on the motor base 1012. When the wiping mechanism 20 is set at a higher height, the height of the horizontal bracket 1063 relative to the base 1061 (ground) is also higher. To ensure that the rotating shaft 1011 of the timing motor 101 can pass through the connection between the horizontal bracket 1063 and the vertical bracket 1062 to connect to the rotating disk 102, the motor base 1012 is disposed below the timing motor 101, so that the height of the timing motor 101 relative to the base 1061 (ground) can be adjusted by the motor base 1012 to match the setting height of the wiping mechanism 20.

[0046] Bearing 103 is fixed to rotating disk 102, and slideway 104 is sleeved on the outside of bearing 103. One end of the drive rod is connected to slideway 104, and the other end of the drive rod passes through first and second stop rings 1051 and 1052 on horizontal bracket 1063. The drive rod is horizontal and reciprocates horizontally on horizontal bracket 1063.

[0047] The bearing 103 rotates as the rotating disc 102 is driven by the timing motor 101. As the rotating disc 102 rotates, the bearing 103 generates a force on the slide 104 to push the slide 104 to move, thereby causing the driving rod to follow the slide 104 and reciprocate in the horizontal direction along the fixed bracket.

[0048] The bearing 103 is located at a non-center position of the rotating disc 102, which can ensure that the bearing 103 can push the slideway 104 to move as the rotating disc 102 rotates, thereby driving the driving rod to perform reciprocating motion.

[0049] In some embodiments, one or two driving rods may be provided. Based on the different number of driving rods provided, the positions of the first limiting ring 1051 and the second limiting ring 1052 relative to the horizontal bracket 1063 are also different, and the structure of the slideway 104 is also different.

[0050] In the first marking durability testing device, the driving rods may include a first driving rod 1071 and a second driving rod 1072, which are connected by a slide 104 and are in a horizontal position. To facilitate limiting the first driving rod 1071 and the second driving rod 1072, a first limiting ring 1051 and a second limiting ring 1052 are respectively disposed at opposite ends of a horizontal bracket 1063 in the horizontal direction.

[0051] Figure 3 It is a structural diagram of the first slide 104 provided in an embodiment of the present application.

[0052] like Figure 3 As shown, combined with Figure 1 and Figure 2 As shown in the figure, in some embodiments, the first slide 104 may include a slide body 1041 and a first fixed end 1042 and a second fixed end 1043 located at opposite ends of the slide body 1041, and the line connecting the first fixed end 1042 and the second fixed end 1043 is horizontal.

[0053] The first fixed end 1042 is positioned opposite the first limiting ring 1051. One end of the first drive rod 1071 passes through the first limiting ring 1051, and the other end of the first drive rod 1071 is fixedly connected to the first fixed end 1042, so that the first drive rod 1071 is in a horizontal position. The second fixed end 1043 is positioned opposite the second limiting ring 1052. One end of the second drive rod 1072 passes through the second limiting ring 1052, and the other end of the second drive rod 1072 is fixedly connected to the second fixed end 1043, so that the second drive rod 1072 is in a horizontal position. In this way, the first fixed end 1042 and the second fixed end 1043 at both ends of the slide body 1041, as well as the corresponding first limiting ring 1051 and second limiting ring 1052, can limit and fix the first drive rod 1071 and the second drive rod 1072, ensuring that the first drive rod 1071 and the second drive rod 1072 can maintain reciprocating motion in the horizontal direction.

[0054] The slide body 1041 is an annular structure having a through hole 1044. The slide body 1041 is sleeved onto the outer side of the bearing 103 through the through hole 1044. The bearing 103 passes through the through hole 1044, and the diameter of the bearing 103 matches the through hole 1044. When the timing motor 101 drives the rotating disk 102 to rotate, the bearing 103, as the rotating disk 102 rotates, generates a driving force on the slide body 1041 through the through hole 1044, pushing the slide body 1041 to move. The moving slide body 1041, in turn, drives the first and second drive rods 1071 and 1072 to move horizontally via the first and second fixed ends 1042 and 1043.

[0055] Through hole 1044 is an elliptical hole, with its long axis perpendicular to the horizontal direction of first drive rod 1071. This ensures that as bearing 103 rotates with rotating disk 102, through hole 1044 accommodates longitudinal displacement of bearing 103, preventing bearing 103 from becoming stuck within through hole 1044 and affecting the reciprocating motion of the drive rod. In other words, vertical floating during movement of slideway body 1041 is prevented, ensuring the horizontal reciprocating motion of first and second drive rods 1071 and 1072.

[0056] For example, the length of the major axis of the through hole 1044 can be at least twice the distance between the bearing 103 and the center of the rotating disk 102. This ensures that when the bearing 103 rotates with the rotating disk 102, there is sufficient space for it to slide in the through hole 1044 and push the slide body 1041, thus preventing it from getting stuck.

[0057] Figure 4 This is a structural diagram of the second type of identification durability testing equipment provided in an embodiment of the present application.

[0058] like Figure 4 As shown, in the second marking durability testing device, the driving rod may include a first driving rod 1071. To facilitate limiting the first driving rod 1071, a first limiting ring 1051 and a second limiting ring 1052 are spaced apart and disposed at the same end of the horizontal bracket 1053 in the horizontal direction.

[0059] To facilitate the fixation of the first limiting ring 1051 and the second limiting ring 1052, the horizontal bracket 1063 extends a certain distance away from the slide 104. Furthermore, to optimally limit the first drive rod 1071 and ensure that the first drive rod 1071 moves only in the horizontal direction, the spacing between the first limiting ring 1051 and the second limiting ring 1052 on the horizontal bracket 1053 must be as long as possible. For example, the first limiting ring 1051 is located at the end of the horizontal bracket 1063 away from the slide 104, and the second limiting ring 1052 is located at the end of the horizontal bracket 1063 closer to the slide 104. At the same time, the second limiting ring 1052 does not contact the rotating disc 102, preventing interference between the two and hindering the rotation of the rotating disc 102.

[0060] Figure 5 It is a structural diagram of the second slide 104 provided in an embodiment of the present application.

[0061] like Figure 5 As shown, combined with Figure 4 As shown, in some embodiments, the second slide 104 may include a slide body 1041 and a first fixed end 1042. The first fixed end 1042 is located on one side of the slide body 1041, and a line connecting the first fixed end 1042, the first limiting ring 1051, and the second limiting ring 1052 is horizontal.

[0062] One end of the first driving rod 1071 is connected to the first fixed end 1042, and the other end of the first driving rod 1071 passes through the second limiting ring 1052 and the first limiting ring 1051 in sequence. In this way, the second limiting ring 1052 and the first limiting ring 1051 can ensure that the first driving rod 1071 moves only in the horizontal direction.

[0063] The difference between the second slide 104 and the first slide 104 is that the number of fixed ends provided on the slide body 1041 is different. The remaining structure and related functions of the second slide 104 can refer to the contents of the first slide 104 and are not repeated here.

[0064] In some embodiments, whether in the first type of marking durability testing equipment or the second type of marking durability testing equipment, the wiping mechanism 20 may include a wiping member 201 and a prototype slot 202. The wiping member 201 may be a gauze wiper, which is soaked with an industrial cleaning agent, and is used to wipe the marking on the surface of the test prototype 30 to perform a durability test. The industrial cleaning agent may be n-hexane, methanol, alcohol, n-heptane, acetone, etc. The prototype slot 202 is used to place the test prototype 30. During the test, the prototype slot 202 fixes the test prototype 30 to prevent the wiping member 201 from causing the test prototype 30 to move when wiping the surface of the test prototype 30, thereby affecting the accuracy of the test results.

[0065] The wiper 201 may include a fixed end and a wiping end. The fixed end of the wiper 201 is connected to one end of the first drive rod 1071 that passes through the first retaining ring 1051. The wiping end of the wiper 201 faces downward, and the length of the wiper 201 is perpendicular to the direction of movement of the first drive rod 1071. The wiper 201 is fixed to the first drive rod 1071. During testing, the tester's hands do not need to come into contact with the test solution, thereby preventing harm to the human body. The prototype slot 202 is located below the wiper 201, and the wiping end of the wiper 201 abuts the surface of the test prototype 30 placed in the prototype slot 202. The surface of the test prototype 30 has a marking, and the wiping end of the wiper 201 contacts the marking on the surface. The wiper 201 is driven by the first drive rod 1071 and performs a reciprocating wiping motion on the surface of the test prototype 30 to perform a durability test on the marking on the surface of the test prototype 30.

[0066] Figure 6 It is a structural diagram of the prototype slot 202 provided in an embodiment of the present application.

[0067] like Figure 6 As shown, in some embodiments, the prototype slot 202 may include a prototype slot fixed end 2021 and a prototype slot movable end 2022. The prototype slot fixed end 2021 and the prototype slot movable end 2022 are connected by a telescopic component 2023. The telescopic component 2023 is used to adjust the size of the prototype slot 202 formed by the prototype slot fixed end 2021 and the prototype slot movable end 2022 to accommodate test prototypes 30 of different sizes. At the same time, the telescopic component 2023 can also be used to clamp the test prototype 30 between the prototype slot fixed end 2021 and the prototype slot movable end 2022, thereby fixing the test prototype 30 and preventing displacement during the test process that may affect the test results.

[0068] The prototype slot 202 can be placed on the ground or on an object of a certain height. The height of the prototype slot 202 determines the placement height of the timing motor 101, horizontal bracket 1063, first drive rod 1071, and other components of the drive mechanism 10. The height of the prototype slot 202 is compatible with the height of the various components of the drive mechanism 10 and is not specifically limited in this embodiment of the application. It is sufficient to ensure that the wiper 201 of the wiping mechanism 20 can horizontally test the durability of the marking on the surface of the test prototype 30.

[0069] Figure 7 This is a schematic diagram of the first state of the first identification durability testing device provided in an embodiment of the present application.

[0070] like Figure 7As shown, in some embodiments, taking the first type of label durability testing device as an example, in which a label on the surface of a test sample 30 is subjected to a durability test, during the test, the timing motor 101 drives the rotating disk 102 to rotate in a clockwise direction, and drives the bearing 103 to rotate in a clockwise direction along with the rotating disk 102. When the bearing 103 rotates to the leftmost end, the bearing 103 drives the first drive rod 1071 and the second drive rod 1072 to move leftward via the slide 104. Simultaneously, the first drive rod 1071 and the second drive rod 1072 drive the wiping member 20 in the wiping mechanism 20 to move leftward along the surface of the test sample 30, thereby wiping the label on the surface of the test sample 30 in a leftward direction.

[0071] Figure 8 This is a schematic diagram of the second state of the first identification durability testing device provided in an embodiment of the present application.

[0072] like Figure 8 As shown, in some embodiments, when the rotating disc 102 drives the bearing 103 to rotate to the far right in a clockwise direction again, the bearing 103 drives the first drive rod 1071 and the second drive rod 1072 to move to the right through the slide 104. At the same time, the wiping member 201 in the wiping mechanism 20 is driven by the first drive rod 1071 and the second drive rod 1072 to move to the right along the surface of the test sample 30 to wipe the mark on the surface of the test sample 30 in a rightward direction.

[0073] The test process is repeated over a preset test time. The reciprocating horizontal motion of the first and second drive rods 1071, 1072 drives the wiper 201 to perform a reciprocating wiping motion on the surface of the test sample 30. When the preset test time is reached, the wiping motion stops, the test process ends, and the test result is obtained.

[0074] The mark durability test equipment provided by the embodiment of the present application is that at the end of the driving mechanism 10, the timing motor 101 drives the rotating disc 102 to rotate, and the bearing 103 rotating with the rotating disc 102 drives the first driving rod 1071 to do horizontal reciprocating motion through the slide 104. The first driving rod 1071 that does horizontal reciprocating motion drives the wiping member 201 in the wiping mechanism 20 to move back and forth in the horizontal direction to wipe the mark on the surface of the test prototype 30 below the wiping head end of the wiping member 201, and the mark is subjected to durability test. The driving mechanism 10 and the wiping mechanism 20 can be used to automatically test the mark, and the speed of the reciprocating wiping action can be achieved by adjusting the speed of the timing motor 101, thereby achieving accurate control of the test speed (wiping speed), and by setting the running time of the timing motor 101, accurate control of the test time can be achieved. In this way, the test result of the mark durability can be guaranteed to be accurate.

[0075] In some embodiments, the marking durability test device can also accurately control the wiping force (test pressure). Figure 1 、 Figure 2 or Figure 4 As shown, based on the structures of the sign durability testing equipment provided in the aforementioned embodiments, the sign durability testing equipment may further include a pressure adjustment mechanism 40 for adjusting the pressure applied by the wiper 201 to the surface of the test sample 30, that is, adjusting the wiping force. This allows precise control of parameters such as wiping time (test time), wiping force (test pressure), and wiping speed (test rotation speed), ensuring accurate sign durability test results.

[0076] The pressure regulating mechanism 40 may include a lifting platform 401, a stepping motor 402 and a pressure sensor 403. The stepping motor 402 may rotate forward or reverse based on different input pulse signals, forward rotation means one step forward, and reverse rotation means one step backward.

[0077] The stepper motor 402 can be placed on the ground or other stable objects. The stepper motor 402 is arranged in a housing 405. The housing 405 is used to protect the stepper motor 402. In order to facilitate the structure of the stepper motor 402 in the housing 405, Figure 1 、 Figure 4 、 Figure 7 and Figure 8 The housing 405 is shown to be transparent, but in other embodiments, the housing 405 may also be Figure 2 Non-transparent state shown.

[0078] The lifting platform 401 is fixedly connected to the stepper motor 402 and is located above the stepper motor 402. The lifting platform 401 is located below the wiping mechanism 20, and the prototype tank 202 is placed on the lifting platform 401. The lifting platform 401 and the stepper motor 402 can together serve as a placement platform for the prototype tank 202. The overall height of the lifting platform 401 and the stepper motor 402 determines the placement height of the prototype tank 202, and thus determines the placement height of the timing motor 101, the horizontal bracket 1063, the first drive rod 1071, and other components of the drive mechanism 10.

[0079] The pressure sensor 403 is fixed to the first drive rod 1071. To achieve this, a sensor fixing ring 404 is provided on the end of the first drive rod 1071 away from the slideway 104. The pressure sensor 403 is fixedly connected to the first drive rod 1071 via the sensor fixing ring 404. The sensing surface of the pressure sensor 403 faces downward, and the wiper 201 is fixed to the sensing surface of the pressure sensor 403. For example, the fixing method can be adhesive. When the wiper 201 wipes horizontally on the marking on the surface of the test sample 30, the pressure sensor 403 detects the wiping force applied by the wiper 201 to the test sample 30, i.e., the real-time test pressure.

[0080] For example, the thrust generated by the first driving rod 1071 on the pressure sensor 403 Wherein, torque and lead are the torque and lead of the timing motor 101, and n is the efficiency of the timing motor 101. Then, the pressure sensor 403 detects the real-time test pressure P=FG applied by the wiper 201 to the test sample 30, where G is the total weight of the pressure sensor 403 and the wiper 201.

[0081] When the real-time test pressure does not meet the preset test pressure, the stepper motor 402 controls the lifting platform 401 to rise or fall, thereby adjusting the pressure applied by the wiper 201 to the test sample 30 so that the test pressure is always within the preset test pressure range. For example, the preset test pressure can be 1N-50N.

[0082] Figure 9 This is a control block diagram of the identification durability testing device provided in an embodiment of the present application.

[0083] like Figure 9 As shown, in some embodiments, the marking durability test device may further include a main control system 50, which is connected to the timing motor 101, the stepper motor 402, and the pressure sensor 403. The main control system 50 is used to drive the timing motor 101 to operate, and to drive the stepper motor 402 to operate based on the comparison result between the test pressure detected by the pressure sensor 403 and the preset test pressure. It should be noted that the marking durability test device also includes a power module (not shown in the figure) for supplying power to the main control system 50, the timing motor 101, the stepper motor 402, and the pressure sensor 403.

[0084] When performing a durability test on the marking on the surface of the test sample 30, the preset test time, preset test speed, preset test pressure, and the speed of the stepper motor 402 are input into the main control system 50, and then the timing motor 101 and the pressure sensor 403 are started. For example, the speed of the stepper motor 402 can be 20-100 rpm.

[0085] After the timing motor 101 is running, it drives the rotating disc 102 to rotate, and synchronously drives the bearing 103 on the rotating disc 102 to rotate. The rotating bearing 103 drives the first drive rod 1071 to reciprocate in the horizontal direction through the slide 104. The movement of the first drive rod 1071 moves the end with the pressure sensor 403 and the wiper 201 to the top of the test sample 30, so that the wiper 201 can wipe the mark on the surface of the test sample 30 in the horizontal direction with a preset test pressure. The wiping time during the entire test process is the preset test time, and the wiping speed corresponds to the preset test speed. When the test time reaches the preset test time, the timing motor 101 stops and the test ends.

[0086] A data line is provided in the first drive rod 1071 and the second drive rod 1072, and the data line is used to realize the connection between the pressure sensor 403 and the main control system 50. During the test process, the pressure sensor 403 detects the test pressure applied by the wiper 201 to the test sample 30 in real time and transmits it back to the main control system 50. The main control system 50 determines whether the test pressure detected in real time is within the preset test pressure range based on the preset test pressure input in advance. If it is not within the preset test pressure range, the main control system 50 sends an instruction to the stepper motor 402, starts the stepper motor 402, and controls the stepper motor 402 to drive the lifting platform 401 to rise or fall, so as to increase or decrease the test pressure applied by the wiper 201 to the test sample 30, until the test pressure detected in real time is within the preset test pressure range, and the stepper motor 402 stops working.

[0087] The marking durability test equipment provided by the embodiment of the present application is characterized in that, at the end of the wiping mechanism 20, the pressure sensor 403 detects in real time the test pressure of the wiping member 201 in the wiping mechanism 20 when wiping the marking on the surface of the test prototype 30, and feeds back the real-time detected test pressure to the main control system 50. If the main control system 50 determines that the real-time detected test pressure is not within the preset test pressure range, it controls the stepper motor 402 to drive the lifting platform 401 to rise or fall, so as to increase or decrease the test pressure applied by the wiping member 201 to the test prototype 30, so that the test pressure meets the preset test pressure range, and the precise control of the test pressure can be achieved. At the same time, by adjusting the speed of the timing motor 101, the speed of the reciprocating wiping action can be achieved, and the precise control of the test speed (wiping speed) can be achieved, and by setting the running time of the timing motor 101, the precise control of the test time can be achieved. In this way, the test results of the durability of the marking can be guaranteed to be accurate.

[0088] Figure 10 This is a flow chart of the marking durability testing method provided in an embodiment of the present application.

[0089] like Figure 10 As shown, in some embodiments, a label durability testing method is implemented based on the label durability testing device proposed in any of the aforementioned embodiments. The label durability testing method may include the following steps:

[0090] Step S100: Start the timing motor in the marker durability testing device.

[0091] Among them, the timing motor 101 drives the rotating disc 102 to rotate according to the preset test time and the preset test speed. The bearing 13 on the rotating rotating disc 102 drives the driving rod to reciprocate in the horizontal direction through the slide 104, thereby driving the wiping member 201 at one end of the driving rod to perform a reciprocating wiping action on the surface of the test sample 30.

[0092] For example, the preset test time is 15 seconds and the preset test speed is 60 r / min inputted into the main control system 50. The main control system 50 starts the timing motor 101 and makes the timing motor 101 run with the preset test time of 15 seconds and the preset test speed of 60 r / min as the operating parameters.

[0093] The timing motor 101 drives the rotating disk 102 to rotate, which in turn moves the pressure sensor 403 above the test sample 30 via the first drive rod 1071. The test sample 30 is placed in the sample slot 202 with the surface bearing the marking facing upward, ensuring that the longitudinal centerline of the test sample 30 coincides with the centerline of the tensile direction of the sample slot 202. The horizontal reciprocating motion of the first drive rod 1071 drives the wiper 201 to rub the marking on the surface of the test sample 30 at a preset test speed.

[0094] Step S200: Acquire the test pressure applied by the wiper to the surface of the test sample detected by the pressure sensor in the marking durability testing equipment.

[0095] The preset test pressure can be a specific value or a range of values. For example, a preset test pressure range of 4.9N-5.1N is input into the main control system 50 , and the speed of the stepper motor 402 is input to 60 rpm, which is then started. The pressure sensor 403 detects the pressure between the wiper 201 and the test sample 30 in real time and reports this to the main control system 50.

[0096] The main control system 50 compares the real-time test pressure returned by the pressure sensor 403 with the preset test pressure range to determine whether the real-time test pressure is within the preset test pressure range.

[0097] Step S300: If the test pressure does not meet the preset test pressure, control the stepper motor to adjust the height of the lifting platform below the test sample to adjust the test pressure applied by the wiping member to the surface of the test sample.

[0098] If the main control system 50 determines that the real-time test pressure is lower than the minimum value corresponding to the preset test pressure range, it starts the stepper motor 402 in forward rotation, controlling the stepper motor 402 to drive the lifting platform 401 upward. As the lifting platform 401 rises, the pressure sensor 403 again detects the test pressure in real time until the test pressure applied by the wiper 201 on the surface of the test sample 30 meets the preset test pressure range.

[0099] If the main control system 50 determines that the real-time test pressure is higher than the maximum value corresponding to the preset test pressure range, it starts the stepper motor 402 in reverse rotation, controlling the stepper motor 402 to drive the lifting platform 401 downward. As the lifting platform 401 descends, the pressure sensor 403 again detects the test pressure in real time until the test pressure applied by the wiper 201 to the surface of the test sample 30 is reduced and the test pressure meets the preset test pressure range.

[0100] The main control system 50 controls the stepper motor 402 to raise or lower the lift platform 401 based on the comparison of the test pressure detected in real time by the pressure sensor 403 with the preset test pressure. This process can be applied both at the initial test moment and during the test. If the main control system 50 detects that the test pressure deviates from the preset test pressure, it will control the stepper motor 402 to adjust the height of the lift platform 401, thereby adjusting the pressure applied by the wiper 201 to the surface of the test sample 30. If the main control system 50 determines that the real-time test pressure is within the preset test pressure range, the main control system 50 will not send a height adjustment instruction to the stepper motor 402, and the wiper 201 will continue to rub the markings on the surface of the test sample 30 based on the current real-time detected pressure.

[0101] During the test, the horizontal reciprocating motion of the first driving rod 1071 drives the wiping member 201 to rub the mark on the surface of the test sample 30 at a preset test pressure and a preset test speed, thereby ensuring the accuracy of the test result.

[0102] Step S400: After the pressure sensor detects that the adjusted test pressure meets the preset test pressure, the stepper motor is stopped.

[0103] Step S500: When the test time meets the preset test time, the timing motor is stopped and the test ends.

[0104] The main control system 50 receives the real-time test pressure returned by the pressure sensor 403 in real time, and when it determines that the preset test pressure is met, it controls the stepper motor 402 to stop running. At this time, the wiper 201 can continue to rub the mark on the surface of the test sample 30 at the preset test pressure.

[0105] The test time is counted from the moment when the wiper 201 starts to rub the mark. If the accumulated test time reaches the preset test time, such as 15 seconds, the main control system 50 controls the timing motor to stop and the test ends.

[0106] In the method for testing the durability of a marking provided in an embodiment of the present application, the main control system 50 controls the rotation of the timing motor 101 based on a preset test time and a preset test speed, thereby driving the drive rod to reciprocate in the horizontal direction through the coordinated action of the rotating disk 102, the bearing 103, and the slide 104. The reciprocating drive rod drives the wiper 201 to wipe the marking on the surface of the test sample 30 reciprocally in the horizontal direction. The main control system 50 compares the test pressure applied by the wiper 201 to the surface of the test sample 30 based on the real-time detection of the pressure sensor 403 with the preset test pressure. When the preset test pressure is not met, the main control system 50 sends a control instruction to the stepper motor 402, which drives the lifting platform 401 to rise or fall, thereby adjusting the test pressure applied by the wiper 201 to the surface of the test sample 30, so that the test pressure is constant during the test process, thereby achieving precise control of the test pressure. At the same time, the speed of the reciprocating wiping action can be adjusted by adjusting the rotation speed of the timing motor 101, thereby achieving precise control of the test rotation speed (wiping speed), and the test time can be precisely controlled by setting the running time of the timing motor 101. In this way, the test results of the durability of the mark can be guaranteed to be accurate.
