Description

Technical Field

[0001] The present invention relates to the field of measurement technology, and in particular to a bonding strength detector calibration device and a measuring method. Background Art

[0002] The bond strength tester is referred to as the tester for short. It is mainly used to test the tensile bond strength between the surface layer and the base layer of exterior wall building facing brick materials, insulation materials, reinforcement materials, etc. It plays a very critical role in the quality control of construction projects.

[0003] With the development of society and economy, people's demand for interior and exterior decoration of buildings has increased significantly. The pursuit of aesthetics by adhering decorative tiles to exterior walls and floor tiles indoors has led to related safety issues. For example, tiles cannot be firmly bonded to walls or floors, which can become loose after short-term use. Accidents such as tiles falling off during exterior wall decoration, causing damage to vehicles and injuries to people, are also frequent, seriously threatening people's lives and property losses. Therefore, the accuracy of the detectors used to detect materials such as exterior wall decorative tiles is extremely important.

[0004] The tester consists of a digital test display system and a hydraulic or mechanical loading system. This system applies force to the object being measured, and the digital test display directly or indirectly indicates the applied force. Ensuring the accuracy and reliability of the tester's measurements requires a comprehensive set of calibration equipment with comprehensive functionality and performance for precise measurement.

[0005] Currently, most of the existing similar devices are used for temporary and simple verification and calibration. The standard force gauge of the device is connected to the tester by pressing or pulling the force, and the tester is compared with the standard force gauge to obtain the accuracy of the tester's value. However, the existing similar devices have the following problems:

[0006] The inaccurate calibration results are caused by the poor alignment of the axis of the detector and the standard dynamometer of the device, the susceptibility of the calibration process to external interference, and the circumferential movement during the initial loading period. Summary of the Invention

[0007] In order to solve the above-mentioned problems in the prior art, the present invention provides a bonding strength tester calibration device and a measurement method, so as to make the calibration results of the tester more accurate.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] In a first aspect, the present invention provides a bonding strength tester calibration device, comprising a measuring instrument module, a positioning and centering mechanism, and a loading and driving mechanism;

[0010] The measuring instrument module includes a standard force gauge and a first connecting member, wherein a first end of the first connecting member is connected to the standard force gauge, and a second end of the first connecting member is used to connect to the detector to achieve force value transmission;

[0011] The positioning and centering mechanism includes an up-down adjustment mechanism and a sleeve. The up-down adjustment mechanism is arranged above the first connecting member, and a first positioning member is provided at one end facing the first connecting member. The interior of the sleeve is adapted to the head of the detector, and a second positioning member is provided on the outer side of the bottom surface at a position corresponding to the central axis of the detector and is positioned and connected to the first positioning member.

[0012] The loading drive mechanism is located on one side of the first connecting member and is used to drive the operating handle of the detector to complete verification and calibration.

[0013] The beneficial effects of the present invention are: when the detector needs to be calibrated and checked, when the first connecting piece and the standard dynamometer are connected, the sleeve is put on the head of the detector, and the first positioning piece is pressed against the second positioning piece of the sleeve through the up and down adjustment mechanism, so as to achieve the effect of avoiding the deviation of the central axis of the detector and the standard dynamometer to generate parasitic force components; at the same time, the centering mechanism maintains the pressing state of the detector during the initial loading period and the verification and calibration process, thereby solving the problems of the detector being prone to circumferential movement in the no-load state or during the initial loading period, and the verification and calibration process being easily disturbed by external forces, so that the verification and calibration results of the detector are more accurate.

[0014] Optionally, a convex notch is provided on the second end of the first connecting member, and the lower notch of the convex notch is used for gap-fitting connection with a standard block of the detector.

[0015] According to the above description, since the distance between the standard block and the facing brick surface of almost all detectors is relatively fixed when detecting facing bricks, a convex notch is set on the upper part of the measuring instrument module, which is connected with the gap of the detector standard block, thereby solving the defect of needing to use temporary pads of various thicknesses for space adjustment.

[0016] Optionally, a frame is further included, a measuring groove is provided on the tabletop of the frame, and the measuring instrument module is integrally embedded in the measuring groove and detachably connected to the measuring groove.

[0017] According to the above description, the measuring instrument module is assembled and disassembled on the workbench by integrally embedded means, so as to achieve the effects of barrier-free and rapid assembly and disassembly and precise positioning of the shape.

[0018] Optionally, a calibration tool is further included, and the measuring instrument module further includes a workbench for placing the detector and a ball head mechanism, wherein the workbench is provided with flanges on two opposite sides, and at least one of the flanges is provided with a convex shoulder;

[0019] The calibration fixture is in the shape of a U-shaped tool. A sliding mechanism and a locking mechanism are provided on both sides of the calibration fixture. The flange is slidably connected to the sliding mechanism. The locking mechanism is locked with the measuring instrument module when the sliding mechanism slides to the convex shoulder.

[0020] The ball head mechanism is sleeved on the first end of the first connecting member and is used for docking with the force standard machine.

[0021] According to the above description, when it is necessary to trace the measurement value of the measuring instrument module through a force standard machine, a U-shaped calibration fixture is configured to simulate the contact between the measuring instrument module workbench and the bottom surface of the detector to achieve a force value transfer state that is consistent, thereby achieving the overall calibration accuracy and reliability of the measurement value transfer with a load-bearing state that is closest to the same contact surface, effectively avoiding the introduction of additional measurement errors due to only adopting a local component method for calibration.

[0022] Optionally, the loading drive mechanism includes a drive motor, a handle adapter and a three-dimensional adjustment mechanism, the drive motor is connected to the handle adapter, and the three-dimensional adjustment mechanism is connected to the handle adapter;

[0023] The handle adapter is provided with a universal U-shaped groove facing the operating handle of the detector, and the universal U-shaped groove is used to adapt to the operating handle of the detector.

[0024] According to the above description, the three-dimensional adjustment mechanism can be adjusted at any position within a certain test space so that the handle adapter and the operating handle of the detector can be adapted and disassembled, thereby realizing fast and barrier-free matching and disassembly of different types and different operating handles. The handle adapter is then driven by a drive motor to rotate, thereby realizing loading and driving of the detector.

[0025] Optionally, a display control instrument is further included, and the display control instrument is electrically connected to the standard dynamometer.

[0026] Optionally, the positioning and centering mechanism includes a cantilever beam support;

[0027] The up and down adjustment mechanism includes an adjustment handle and an adjustment screw. The adjustment handle is connected to one end of the adjustment screw. The other end of the adjustment screw is a first positioning piece with a truncated cone protrusion. The first positioning piece passes through the cantilever beam of the cantilever beam bracket and is positioned and connected with the second positioning piece in the truncated cone groove.

[0028] According to the above description, the centering and pressing of the detector is achieved by the positioning cooperation of the frustum protrusion and the frustum groove and by adjusting the rotation and pressing of the screw rod.

[0029] Optionally, the measuring instrument module and the positioning and centering mechanism are provided in one or more sets on the table of the rack.

[0030] According to the above description, it can be seen that by arranging one or more sets of measuring instrument modules and positioning and centering mechanisms on the rack, the demand for simultaneous verification and calibration of multiple detectors can be realized.

[0031] Optionally, the measuring instrument module and the loading drive mechanism are provided with a communication module, and the communication module is used for communicating with an intelligent control and data acquisition system.

[0032] According to the above description, by communicating with the intelligent control and data acquisition system, the automatic data collection and analysis can be made more accurate and reliable, and the intelligent level of verification is correspondingly improved.

[0033] In a second aspect, the present invention provides a bonding strength tester measurement method, using a bonding strength tester calibration device according to the first aspect, comprising the following steps:

[0034] S1. Fixing the detector to the first connecting piece;

[0035] S2. Put the sleeve on the head of the detector, and use the up and down adjustment mechanism to make the first positioning piece press against the second positioning piece of the sleeve to achieve centering and tightening of the detector;

[0036] S3. Manually or automatically drive the operating handle of the tester by hand cranking or with the aid of a loading drive mechanism, and load and unload the tester at a preset rate according to the calibration force value points;

[0037] S4. Record the measurement results, calculate the required technical indicators and automatically determine whether they meet the requirements;

[0038] S5. Remove the detector from the first connector, check whether the device has any faults or damage, and recover it, thereby completing all verification and calibration work;

[0039] S6. When the verification and calibration data needs to be uploaded to the intelligent control and data acquisition system, it can be transmitted manually or through intelligent communication, or sent to the cloud platform server through the Internet of Things or Ethernet for monitoring and management.

[0040] Among them, the technical effect corresponding to the bonding strength tester measurement method provided by the second aspect refers to the relevant description of the bonding strength tester calibration device provided by the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0060] Example 1

[0061] Please refer to Figures 1 to 6 、 Figure 9 A bonding strength tester calibration device includes a measuring instrument module 1, a positioning and centering mechanism 2, a loading and driving mechanism 3, a frame 4 and a display and control instrument 6.

[0062] Please refer to Figure 3 and Figure 5 The measuring instrument module 1 includes a standard force gauge 11, a first connecting member 12, and a workbench 13. The display control instrument 6 is electrically connected to the standard force gauge 11. A measuring groove 42 and a relief groove 43 are provided on the tabletop 41 of the frame 4. The measuring instrument module 1 is integrally embedded within the measuring groove 42 and is detachably connected thereto, enabling quick assembly and disassembly and precise positioning. The relief grooves 43 are provided on either side of the measuring groove 42, allowing the user to reach into the relief grooves 43 to retrieve the measuring instrument module 1, facilitating quick assembly and disassembly.

[0063] like Figure 5 As shown, the first connecting member 12 in this embodiment is Y-shaped as a whole, with its first end being rod-shaped and docking with the standard dynamometer 11, and its second end being a cylinder. A convex notch 121 is provided on the side of the cylinder. The convex notch 121 is U-shaped when viewed from top to bottom, and can be divided into an upper notch and a lower notch from the side. The upper notch of the convex notch 121 is used to adapt to the connecting rod of the detector 100, and the lower notch is used to be clearance-fitted with the standard block 101 of the detector 100 to achieve force transmission.

[0064] In the prior art, a reaction force device is used in conjunction with a standard dynamometer 11 for verification and calibration. This method generally involves making a self-made, piece-part reaction force device, which is then connected in series with the tester 100 and the standard dynamometer 11 to achieve verification and calibration. In this case, temporary pads of various thicknesses are required for different specifications of the tester 100. This is not only cumbersome but may also cause the force axis of the tester 100 to not coincide with the axis of the device, resulting in the generation of some parasitic forces that adversely affect the accuracy of the verification and calibration. In this embodiment, since the standard block 101 of the tester 101 has universal dimensions, such as 40 mm × 40 mm × 8 mm, and the spacing between the standard block 101 and the surface of the facing tiles is relatively fixed when almost all testers 100 are used to test facing tiles, a convex notch 121 is provided on the measuring instrument module 1 to be loosely connected to the standard block 101 of the tester 100. This convex notch 121 solves the problem of previously requiring the use of temporary pads of various thicknesses for spatial adjustment.

[0065] Please refer to Figures 3 to 5 The positioning and centering mechanism 2 includes a cantilever beam bracket 23, an up and down adjustment mechanism 21 and a sleeve 22. The up and down adjustment mechanism 21 is arranged above the first connecting member 12, that is, above the detector 100, and a first positioning member is provided at one end facing the first connecting member 12. The interior of the sleeve 22 is adapted to the head of the detector 100, and a second positioning member is provided on the outer side of the bottom surface at a position corresponding to the central axis of the detector 100, which is positioned and connected to the first positioning member.

[0066] Specifically, the up-and-down adjustment mechanism 21 includes an adjustment handle 212 and an adjustment screw 213. The adjustment handle 212 is connected to one end of the adjustment screw 213. The other end of the adjustment screw 213 is a first positioning member of the truncated cone protrusion 211. The first positioning member passes through the cantilever beam of the cantilever beam bracket 23 and is positioned and connected to the second positioning member of the truncated cone groove 221. The cooperation between the truncated cone protrusion 211 and the truncated cone groove 221 can correct the deviation of the detector 100.

[0067] Among them, the standard block 101 and the connecting rod of the detector 100 are located on the central axis, and the connection rod is connected to the central axis. Figure 5 It can be seen that in this embodiment, the central axes of the adjusting handle 212, the adjusting screw 213, the conical protrusion 211, the conical groove 221, the sleeve 22, and the convex notch 121 are all on the same axis as the central axis of the detector 100, so that the centering of the detector 100 is more accurate.

[0068] Therefore, when it is necessary to calibrate the detector 100, the first end of the first connecting member 12 is connected to the standard dynamometer 11, and the sleeve 22 is put on the head of the detector 100. Then the user drives the adjusting screw 213 downward by adjusting the handle 212 until the conical protrusion 211 is positioned and pressed onto the conical groove 221, thereby realizing the centering and pressing of the detector 100, and achieving the effect of avoiding the deviation of the central axis of the detector 100 and the standard dynamometer 11 to generate parasitic force components; at the same time, the positioning and centering mechanism 2 maintains the pressing state of the detector 100 during the initial loading period and the calibration process, thereby solving the problems such as the detector 100 being prone to circumferential movement in the no-load state or during the initial loading period and the calibration process being easily disturbed by external forces, making the calibration results of the detector 100 more accurate.

[0069] Please refer to Figures 3 to 6 The loading drive mechanism 3 is located on one side of the first connecting member 12 and is used to drive the detector 100 to complete verification and calibration.

[0070] Specifically, the loading drive mechanism 3 includes a drive motor 31 , a handle adapter 32 and a three-dimensional adjustment mechanism 33 . The drive motor 31 is connected to the handle adapter 32 , and the three-dimensional adjustment mechanism 33 is connected to the handle adapter 32 .

[0071] The three-dimensional adjustment mechanism 33 includes an up-and-down sliding assembly 331, a left-and-right sliding assembly 332, a front-and-back sliding assembly 333, and a quick-release lock 334. The sliding assembly is based on the cooperation of the slider and the guide rail to achieve arbitrary position adjustment within a certain test space. In other embodiments, the three-dimensional adjustment mechanism 33 can be a mechanism capable of three-dimensional adjustment, such as a three-dimensional robotic arm, and the sliding assembly can also be a mechanism capable of sliding, such as a cylinder or oil pressure.

[0072] like Figure 3 As shown, the handle adapter 32 is provided with a universal U-shaped groove 321 facing the operating handle 102 of the detector 100, and the universal U-shaped groove 321 is used to adapt to the operating handle 102 of the detector 100. The opening width dimension of the universal U-shaped groove 321 is 2-5mm larger than the width dimension of the most commonly used operating handle 102, and the universal U-shaped groove 321 can be adjusted by using handle adapters 32 with different openings or by providing movable mechanisms on both sides of the universal U-shaped groove 321. Thus, the universal U-shaped groove 321 is provided with a relatively loose clearance fit with the operating handle 102 of the detector 100, and the opening size is adjustable, so as to achieve fast and barrier-free matching and disassembly of different types and different operating handles 102, and has good versatility. After the position is matched, the ball screw slider is locked and positioned using a quick lock 334, and then the ball screw is driven by a servo or stepper motor to drive the loading method, so that the detector 100 can be automatically loaded.

[0073] In this embodiment, one or more sets of measuring instrument modules 1 and positioning and centering mechanisms 2 are provided on the table 41 of the frame 4. For example, if the bonding strength tester 100 in this embodiment includes a carbon fiber bonding strength tester and a multifunctional strength tester, each of which requires a calibration station, two sets of measuring instrument modules 1 and positioning and centering mechanisms 2 can be provided, and the drive motor 31 and handle adapter 32 in the loading drive mechanism 3 are both two sets. The three-dimensional adjustment mechanism 33 can share one set or have two corresponding sets. When sharing one set, the three-dimensional adjustment mechanism 33 and the handle adapter 32 can be detachably connected, such as by a snap-fit ​​connection, a magnetic connection, etc., so that after the handle adapter 32 of one set is positioned, it can be moved to the other set to position the handle adapter 32 of the other set. Alternatively, the loading drive mechanism 3 can be a single set, so that a single set of loading drive mechanism 3 can be used to load and drive the tester 100 of any range specification at multiple stations to complete the calibration work. In order to solve the problem that there is only one verification and calibration station, it is impossible to calibrate multiple detectors 100 at the same time, or it is impossible to apply to detectors 100 of different ranges and categories, the length and width of the whole machine frame 4 are increased according to the structure, range size and other requirements of different detectors 100, so as to achieve the purpose of setting up multiple verification and calibration stations on the table 41, and finally meet the relevant verification and calibration needs.

[0074] like Figure 9 As shown, the measuring instrument module 1 and the loading drive mechanism 3 are provided with a communication module 34, which is used to communicate with the intelligent control and data acquisition system 200. The communication module 34 can be a wireless communication module or a wired communication module. The wireless communication module can be Wi-Fi, 4G, 5G, etc.

[0075] Therefore, in order to address the shortcoming that manual operation cannot realize automatic data collection and processing, an intelligent control and data acquisition system 200 is developed. A control system is used to accurately control the loading / unloading of the force value verification and calibration process, and a control system is designed to simulate the engineering operator using the detector 100 to drive the loading law and status monitoring. Through the Internet of Things, Ethernet and computer online communication control, the automatic reading of the verification and calibration data is realized, and the automatic data collection and analysis is made more accurate and reliable, which also correspondingly improves the intelligent level of verification and calibration. At the same time, the test data collected by the intelligent control and data acquisition system 200 can also be sent to the cloud platform server through the Internet of Things and Ethernet; the cloud platform server verifies and calibrates the facing tile bonding strength tester based on the test data, eliminating the measurement error caused by different personnel operations, and realizing paperless data recording, which is conducive to the monitoring and management of the detector 100 during the verification and calibration process.

[0076] The first embodiment of the present invention provides a universal calibration device that meets the calibration requirements of the detector 100 in accordance with relevant technical specifications, so as to achieve arbitrary adjustment of the test space, precise centering and positioning, barrier-free and rapid installation, manual and automatic control of loading and unloading, intelligent collection and analysis of calibration data and generation of record reports, as well as automatic reading of calibration data through the Internet of Things, Ethernet and computer online communication control, making automatic data collection and analysis more accurate and reliable, and monitoring and management of the detector 100 during the calibration process.

[0077] Example 2

[0078] In the prior art, a force standard machine is a more accurate force measuring machine. The calibration device needs to be calibrated by the force standard machine at regular intervals. However, the prior art cannot perform overall value traceability and can only disassemble the standard force gauge 11 of the device into separate parts. This is likely to introduce additional measurement errors due to the fact that only a partial component method is used for calibration, resulting in inconsistency with the actual force state. This leads to uncertainty in the value traceability of the device. Therefore, this second embodiment is further defined on the basis of the above-mentioned first embodiment as follows:

[0079] Please refer to Figures 1 to 8 A bonding strength tester calibration device also includes a calibration tool 5, the measuring instrument module 1 also includes a ball head mechanism 14, the ball head mechanism 14 includes a ball head pair 141 and a customized nut press head 142, which is similar to a male and female head or a ball head and a ball socket. The ball head pair 141 and the customized nut press head 142 are in accordance with Figure 5 The customized nut press head 142 is sequentially sleeved on the first end of the first connecting member 12 and is used to transmit the force of the force standard machine to the ball head pair 141.

[0080] like Figure 7 As shown, flanges 131 are provided on all four sides of the workbench 13 of the measuring instrument module 1. The flanges 131 on the two long sides are provided with raised shoulders 132. The flanges 131 on the two short sides serve as contact surfaces for receiving force and facilitating user handling of the measuring instrument module 1. In other embodiments, flanges 131 are provided on at least two opposing sides of the workbench 13 of the measuring instrument module 1. These two sides may correspond to or be staggered with the avoidance groove 43. The flanges 131 may fully or partially cover the side edges. When the side edges where the flanges 131 are located are staggered with the avoidance groove 43, the other two sides of the workbench 13 may be provided with grippable portions, such as handles.

[0081] like Figure 8As shown, the calibration tooling 5 is U-shaped. Sliding mechanisms and locking mechanisms are provided on both side surfaces of the calibration tooling 5. Among them, the sliding mechanism is a drawer-type guide rail 51, and the locking mechanism is a locking screw 52. The flange 131 is slidably connected to the drawer-type guide rail 51. When the drawer-type guide rail 51 slides to the boss shoulder 132, the locking screw 52 locks with the measuring instrument module 1. In this way, the contact mode between the calibration tooling 5 and the workbench 13 is the same as the contact mode between the bottom surface of the detector 100 and the workbench 13 of the measuring instrument module 1. In this way, the force value transfer state consistent calibration is carried out by simulating the contact mode between the workbench 13 of the measuring instrument module 1 and the bottom surface of the detector 100 on the calibration tooling 5.

[0082] Therefore, when using the force standard machine to trace the quantity value of this device, the calibration tooling 5 is installed on the workbench 13 of the measuring instrument module 1. The two slide in through the drawer-type guide rail 51 and are positioned to the limit position by means of the provided boss shoulder 132, and are fastened into a whole module with the locking screw 52. Then, the whole module is placed upside down on the calibration work surface of the force standard machine, and the upper ball indenter of the force standard machine is aligned with the customized nut indenter 142 of the measuring instrument module 1, and then the standard force value can be applied to achieve the overall calibration accuracy and reliability of the force value transfer in the closest bearing state of the same kind of contact surface. Thus, the overall quantity value traceability of the device can be realized by using the force standard machine without disassembling it into scattered parts, so as to eliminate the additional measurement errors introduced by adopting the component method for calibration, and avoid some uncertainties in the quantity value traceability of calibrating this device.

[0083] After the implementation of this embodiment is applied industrially, it will bring very good economic and social benefits: First, this calibration device can be provided for testing companies and metrological technical institutions to provide strong and reliable technical support for the calibration of the detector 100; Second, it can provide product performance test evaluation for the manufacturers of the detector 100 and provide strong technical support for the control of the qualified rate of the products of the manufacturers; Third, it can effectively guide and standardize the operation behavior, ensure the scientific and reasonable traceability of the quantity value of the detector 100, and meet the technical index requirements and calibration requirements of relevant national technical specifications.
