Description

TECHNICAL FIELD

[0001] The present application relates to a tension detection device, in particular to a composite tape tension detection device based on sensing technology applied in the field of tape tension detection. BACKGROUND

[0002] The existing tape tension detection device is an instrument for measuring the tensile strength of tape. It simulates the tension that the tape bears in actual use by precisely controlling the tension. The device usually includes a motor drive system, a force sensor and a data processing unit. During the test, the tape is fixed on the clamps of the device, and then the tension is gradually applied until the tape breaks. The force sensor records the tension value in real time, and the results are displayed and analyzed by the data processing unit. These devices can provide accurate tension data to help evaluate the quality and performance of the tape, and are widely used in production quality control and research and development fields.

[0003] Chinese patent CN119198319B discloses a tape tension detection method and device. The invention wraps the tape around the fork, and more of the tape surface contacts the fork rod, thereby increasing the friction. When tension acts on the tape, this friction will prevent the tape from sliding, making the tape more tightly wrapped around the fork. In addition, the multi-layer structure formed by winding also increases the friction between the layers, which makes the entire tape roll more tightly combined together, further enhancing the stability of the tape on the fork.

[0004] Chinese patent CN119510126A discloses a tension-adjustable tension testing machine. The invention proposes a tension-adjustable tension testing machine with reinforcement function. The invention makes the tape not fall off by loosening the knob due to the tension, thereby enhancing the stability of the tape.

[0005] The existing tape tension detection equipment mostly performs single direction tensile test, has certain limitations, is not easy to simulate different tensile conditions, and has insufficient clamping adaptability and is inconvenient to replace. The attachments on some tapes may adhere to the clamping parts during clamping, affecting the surface cleanliness of the clamping parts, and the contaminated clamping parts continue to be used, which may affect the subsequent tape test. SUMMARY

[0007] To address the aforementioned problems, this invention provides a composite tape tensile testing device based on sensor technology, comprising a testing platform, a pair of longitudinal guide rails, a gantry frame covering the testing platform connected between the movable ends of the pair of longitudinal guide rails, clamping assemblies connected to both the gantry frame and the testing platform, a lifting cylinder connected between the gantry frame and the clamping assemblies, and a transverse guide rail connected between the lifting cylinder and the top of the gantry frame; the clamping assembly includes a C-shaped shell with a trapezoidal hole, and a pair of clamping blocks detachably installed inside the trapezoidal hole; a strain gauge pressure sensor is provided at one end of each clamping block, and a docking hole is provided at the other end;

[0008] Each of the two inclined inner walls of the trapezoidal hole has a sliding groove, and a slider is slidably connected in the groove. A telescopic electromagnetic push-pull rod is connected to the slider. The movable end of the electromagnetic push-pull rod is connected to a locking pin for rotating engagement with the mating hole. A dual-axis motor for adjusting the height of the pair of sliders is installed inside the C-shaped shell. A rotating plate for limiting and clamping blocks is rotatably connected to the side opening of the trapezoidal hole.

[0009] In the aforementioned composite tape tensile testing device based on sensor technology, the tape can be adaptively clamped by clamping components and clamping blocks, and the force changes during the tape tensile test can be monitored in real time.

[0010] As a further supplement to this application, the dual-axis motor and the slider are connected by a transmission structure, which includes a lead screw that is threadedly connected to the slider and is rotatably connected inside a C-shaped housing. The lead screw and the power output end of the dual-axis motor are respectively connected to mutually matched bevel gears.

[0011] As a further addition to this application, the rotating plate is provided with a tangent edge. When the rotating plate rotates until the tangent edge is parallel to the inclined side of the trapezoidal hole, the limiting position of the rotating plate on the clamping block is released.

[0012] As a further supplement to this application, the mating hole and the snap-fit ​​post are respectively equipped with a mating socket and a mating connector that are mutually matched, and the mating socket is rotatably connected in the mating hole and electrically connected to the strain gauge pressure sensor.

[0013] As a further supplement to this application, the electromagnetic push-pull rod includes a telescopic rod connected to a locking post. The locking post and the slider are connected by an elastic wire. An electromagnet is installed at one end of the telescopic rod, and a permanent magnet matching the electromagnet is installed inside the locking post.

[0014] As a further addition to this application, when the slider moves to the maximum displacement, the upper and lower ends of the corresponding clamping block match the upper and lower ends of the trapezoidal hole, respectively.

[0015] As a further addition to this application, a laser receiver and a laser emitter for positioning calibration are installed at the top of each clamping assembly.

[0016] As a further supplement to this application, it also includes an auxiliary adjustment system, which includes a processor; the processor is connected to a control module, a data processing module, a data acquisition module and a data storage module;

[0017] The control module is used to control each execution component to work according to preset programs and instructions;

[0018] The data processing module is used to process and analyze the monitoring data collected by the data acquisition module;

[0019] The data acquisition module is used to collect various monitoring data throughout the tensile testing process;

[0020] Data storage module: Used to store processed data and detection results.

[0021] As a further supplement to this application, the control module is provided with a vertical tension mode, a lateral tension test mode, and an oblique tension test mode; in the vertical tension mode and the lateral tension test mode, the rotating plate limits the clamping block, and in the oblique tension test mode, the rotating plate releases the limit on the clamping block.

[0022] The data processing module uses different preset programs to process the monitoring data collected in the vertical tension mode, lateral tension test mode and oblique tension test mode.

[0023] In summary, this solution can perform tensile tests on composite tapes in different directions. The clamping blocks used for data acquisition and tape clamping can be quickly disassembled and replaced to adapt to different types of tapes. They can also be easily adjusted to a fixed or rotatable state according to the test scenario, which can easily improve the accuracy and comprehensiveness of the test results.

[0035] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0036] Implementation method 1:

[0037] Figures 1-5 A composite tape tensile testing device based on sensing technology is shown, including a testing platform 1 and a pair of longitudinal guide rails 2. A gantry frame 3 covering the testing platform 1 is connected between the movable ends of the pair of longitudinal guide rails 2. Clamping components 4 are connected to both the gantry frame 3 and the testing platform 1. A fixed seat is connected between the testing platform 1 and one of the clamping components 4. The two clamping components 4 are electrically connected to an external testing terminal through the gantry frame 3 and the testing platform 1, respectively.

[0038] A lifting cylinder 31 is connected between the gantry frame 3 and another clamping assembly 4, and a transverse guide rail 32 is connected between the lifting cylinder 31 and the top of the gantry frame 3.

[0039] The clamping assembly 4 includes a C-shaped shell 41, in which a pair of clamping blocks 5 are detachably installed. A trapezoidal hole matching the pair of clamping blocks 5 is opened in the middle of the C-shaped shell 41. A strain gauge pressure sensor is laid on the side plane end of the clamping block 5, and a mating hole is opened on the side inclined end of the clamping block 5.

[0040] A pair of inclined inner walls of the trapezoidal hole are provided with sliding grooves, and a slider 42 is slidably connected in the sliding groove. The slider 42 slides vertically along the sliding groove. A telescopic electromagnetic push-pull rod 43 is connected to the slider 42. The movable end of the electromagnetic push-pull rod 43 is connected to a locking post 44 for rotatably engaging with the mating hole. The mating hole and the locking post 44 are respectively equipped with matching mating sockets and mating joints. The mating socket is rotatably connected in the mating hole and electrically connected to the strain gauge pressure sensor. After the mating socket and the mating joint are mated, they are locked together. The strain gauge pressure sensor is prior art. A suitable strain gauge pressure sensor from the prior art can be selected and installed by a person skilled in the art to collect tensile force data when the tape is clamped and stretched. For example, a semiconductor strain gauge of model KSPB-2-120-E3.

[0041] A dual-axis motor 45 for adjusting the height of a pair of sliders 42 is installed inside the C-shaped housing 41. The dual-axis motor 45 is connected to the sliders 42 through a transmission structure, which includes a lead screw threaded to the sliders 42 and rotatably connected inside the C-shaped housing 41. The power output ends of the lead screw and the dual-axis motor 45 are respectively connected to meshing bevel gears. When the power output end of the dual-axis motor 45 rotates, it drives the lead screw to rotate, thereby causing the sliders 42 to slide along the slide groove. When the dual-axis motor 45 is working, the two power output ends rotate synchronously, causing the pair of sliders 42 to move synchronously.

[0042] The electromagnetic push-pull rod 43 includes a telescopic rod connected to the locking post 44. The locking post 44 and the slider 42 are connected by an elastic wire. An electromagnet is installed at one end of the telescopic rod. A permanent magnet matching the electromagnet is installed inside the locking post 44. When the electromagnetic push-pull rod 43 needs to be extended, the electromagnet and the permanent magnet repel each other. At this time, the electromagnetic push-pull rod 43 extends to push the clamping block 5.

[0043] When the electromagnetic push-pull rod 43 needs to be retracted, the electromagnet attracts the permanent magnet, and the locking post 44 drives the telescopic rod extension end to move closer to the electromagnet, so that the electromagnetic push-pull rod 43 retracts to separate from the clamping block 5; when the electromagnetic push-pull rod 43 is fully retracted, the docking socket separates from the docking joint.

[0044] A rotating plate 6 for limiting and holding block 5 is rotatably connected to the side opening of the trapezoidal hole. A circular groove matching the rotating plate 6 is opened at the side opening of the trapezoidal hole. A tangent is provided on the rotating plate 6. When the rotating plate 6 rotates until the tangent is parallel to the inclined side of the trapezoidal hole, the rotating plate 6 is completely retracted into the circular groove. At this time, the limiting of the clamping block 5 by the rotating plate 6 is released. The rotating plate 6 can be set to rotate manually or electrically driven by a motor installed in the C-shaped shell 41.

[0045] When the slider 42 moves to the maximum displacement, the upper and lower ends of the corresponding clamping block 5 match the upper and lower ends of the trapezoidal hole, that is, when the clamping block 5 is placed in the trapezoidal hole and limited by the rotating plate 6.

[0046] When performing tensile testing, the clamping blocks 5 are installed first. During installation, a pair of clamping blocks 5 are placed into the trapezoidal holes of the C-shaped shell 41. After rotating two pairs of rotating plates 6 to limit the clamping blocks 5, the dual-axis motor 45 is controlled to work, so that the slider 42 moves downward to the maximum displacement.

[0047] Then, control the extension of the electromagnetic push-pull rod 43 so that the mating joint on the snap-fit ​​post 44 snaps into the mating socket in the clamping block 5; at this time, the strain gauge pressure sensor is electrically connected to the clamping assembly 4.

[0048] Before clamping the tape, the dual-axis motor 45 and the electromagnetic push-pull rod 43 are controlled to move a pair of clamping blocks 5 away from each other. At the same time, the upper and lower pairs of clamping blocks 5 also move away from each other. At this time, a pair of clamping blocks 5 are opened. Then, the two ends of the tape to be tested, which are cut to the appropriate size, are placed between the clamping blocks 5. Then, the electromagnetic push-pull rod 43 is extended, and the dual-axis motor 45 is activated to adjust the position of the two pairs of clamping blocks 5 so that the two pairs of clamping blocks 5 are close to each other, that is, close to the narrow end of the trapezoidal hole. When the strain gauge pressure sensor on the two pairs of clamping blocks 5 reaches the set value, the adjustment is stopped, and the testing work is prepared.

[0049] During testing, the lifting cylinder 31 is controlled to move the upper clamping component 4 upward to perform a tensile test on the tape. During the tensile process, the strain gauge pressure sensor detects the change in tension and records the peak tension and the moment of breakage data in real time.

[0050] This solution facilitates the disassembly and maintenance of clamping block 5, allows for the replacement of different types of clamping block 5 according to the type of tape being tested, facilitates quick connection during installation of clamping block 5, and makes it convenient to collect tensile force data through clamping block 5 during tensile testing.

[0051] The second implementation method:

[0052] Figures 6-9 As shown, it also includes an auxiliary adjustment system, which includes a processor; the processor is connected to a control module, a data processing module, a data acquisition module and a data storage module;

[0053] The control module is used to control various actuators such as the lifting cylinder 31, the dual-axis motor 45, and the electromagnetic push-pull rod 43 to work according to preset programs and instructions. The control module precisely controls the actuators to realize various operations in the tensile testing process. The control module is equipped with vertical tension mode, lateral tension test mode and oblique tension test mode. In the vertical tension mode and lateral tension test mode, the rotating plate 6 limits the clamping block 5, and in the oblique tension test mode, the limit of the rotating plate 6 on the clamping block 5 is released.

[0054] The data processing module is used to process and analyze the monitoring data collected by the data acquisition module. The data processing module can use preset algorithms and mathematical models to calculate, filter and organize the collected tensile data, and extract useful information, such as peak tensile force and data at the moment of fracture. The data processing module uses different preset programs to process the monitoring data collected in the vertical tensile mode, lateral tensile test mode and oblique tensile test mode.

[0055] The data acquisition module is used to collect various monitoring data throughout the tensile testing process. The monitoring data includes the tensile data of the tape during the stretching process, which is acquired in real time by the strain gauge pressure sensor.

[0056] Data storage module: Used to store processed data and detection results.

[0057] In vertical stretching mode, a pair of clamping components 4 are positioned and calibrated to match each other through a laser receiver and a laser emitter, and then one clamping component 4 is driven to move upward by a lifting cylinder 31 to stretch the tape.

[0058] This solution can perform basic unidirectional tensile tests, and can also simulate multidirectional tensile scenarios through lateral tensile and oblique tensile test modes as needed to meet other simulation testing requirements.

[0059] In the lateral tension test mode, the transverse guide rail 32 is driven to move in the horizontal direction to achieve lateral tension of the tape. During the lateral tension process, the lifting cylinder 31 can also be controlled to drive a clamping component 4 to move upward to simulate different lateral tension conditions.

[0060] In the oblique stretching test mode, first rotate the rotating plate 6 so that multiple rotating plates 6 do not contact the clamping block 5. A pair of clamping components 4 are positioned and calibrated to match each other through the laser receiver and laser emitter. Drive one clamping component 4 forward through the longitudinal guide rail 2 to achieve oblique stretching of the tape. During oblique stretching, the lifting cylinder 31 can also be controlled to drive one clamping component 4 to move upward, or the transverse guide rail 32 can be driven to move horizontally to simulate different oblique stretching conditions.

[0061] This solution enables tensile performance testing of composite tapes in different directions. The clamping block 5, used for data acquisition and tape clamping, can be quickly disassembled and replaced to adapt to different types of tapes. It can also be easily adjusted to a fixed or rotatable state according to the test scenario, which can easily improve the accuracy and comprehensiveness of the test results. Users can easily select different tensile test modes and clamping blocks 5 to meet different test requirements.

[0062] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
