Description

Technical Field

[0001] This utility model relates to the field of carbon fiber testing technology, specifically to an intelligent tester for carbon fiber bonding strength. Background Technology

[0002] The traditional method for testing carbon fiber bond strength is as follows: First, a square or circular test block of a specified size is cut from the central region of a large-volume carbon fiber substrate. Then, a high-strength adhesive is used to fix the standard block to the surface of the test block. To ensure the adhesive fully cures and reaches its final strength, a one-week curing period is required. After curing, a load is applied to the test block using a pull-out device until it detaches from the substrate. The maximum tensile force recorded by the tension sensor at this point is the test result for the bond strength.

[0003] However, the week-long curing waiting period in this method constitutes the most time-consuming part of the entire testing process. This forced settling process not only significantly prolongs the cycle of a single test, but also leads to a large backlog of samples and low testing efficiency. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A carbon fiber bonding strength intelligent tester includes a testing mechanism and a drying mechanism. The testing mechanism includes a support frame, a threaded rod slidingly through the top of the support frame, a tension sensor connected to the bottom end of the threaded rod, a sleeve connected to the bottom of the tension sensor, a T-shaped rod rotatably through the bottom end of the sleeve, a standard component screwed to the bottom end of the T-shaped rod, a sleeve fitted to the top of the support frame and screwed to the threaded rod, and two guide rods slidingly through the top of the support frame and connected to the threaded rod. The drying mechanism includes a square tube movably sleeved on the outside of the standard component, multiple connecting rods connecting the sleeve and the square tube, multiple heating elements installed on the outside of the square tube, an air inlet pipe connected and communicating with the square tube, and multiple flow channels surrounding the outside of the standard component and connected to the square tube. The bottom outer edge of the standard component is arc-shaped.

[0007] By adopting the above technical solution, square or circular test blocks of specified dimensions are cut from the center of a large-volume carbon fiber substrate. After applying a high-strength adhesive to the surface of the test blocks and the bottom of the standard parts, the support frame is tightly attached to the substrate, and the standard parts are bonded to the test blocks. Subsequently, multiple heating elements are turned on and gas is injected into the air inlet pipe. The gas enters the square tube and is indirectly heated by the heating elements. The generated hot air enters the interior of the arc surface through the guide channel and acts on the adhesive between the standard parts and the test blocks. This process significantly shortens the adhesive curing time, reduces the single test cycle, avoids sample accumulation, and improves test efficiency.

[0008] In a preferred embodiment, the present invention can be further configured such that: the sleeve comprises a threaded ring and two levers, the two levers being fixed to both sides of the threaded ring respectively, and the levers being inclined.

[0009] In a preferred embodiment, the present invention can be further configured such that: the guide rod is located on the top of the tension sensor, the two guide rods are respectively located on both sides of the threaded rod, and the top of the guide rod is T-shaped.

[0010] In a preferred embodiment, the present invention can be further configured such that: the air intake pipe slides through the top of the support frame, the flow guide channel is connected to the inside of the square tube, and the bottom end of the flow guide channel extends to the bottom of the arc surface.

[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the rotating sleeve is movably engaged with a housing, and the bottom of the housing is fixedly connected to the top of the support frame.

[0012] In a preferred embodiment, the present invention can be further configured as follows: a temperature sensor is embedded in the top of the support frame, the temperature sensor is close to one end of the support frame, the test end of the temperature sensor is located inside the square tube, multiple heating elements are connected in series, and the heating elements and the temperature sensor are electrically connected to an external PLC.

[0013] In a preferred embodiment, the present invention can be further configured such that: the standard part is provided with a plurality of reinforcing ribs, the reinforcing ribs being made of metal material.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, a square or circular test block of a specified size is cut from the center of a large-volume carbon fiber substrate. After applying a high-strength adhesive to the surface of the test block and the bottom of the standard part, the support is tightly attached to the substrate to bond the standard part to the test block. Subsequently, multiple heating elements are turned on and gas is injected into the air inlet pipe. The gas enters the square tube and is indirectly heated by the heating elements. The generated hot air enters the interior of the arc surface through the guide channel and acts on the adhesive between the standard part and the test block. This process significantly shortens the adhesive curing time, reduces the single test cycle, avoids sample accumulation, and improves test efficiency.

[0016] 2. In this utility model, the temperature sensor measures the temperature inside the square tube in real time, and the measured data is reflected to the external PLC in real time. When the temperature exceeds 50°C, the external PLC shuts down the heating element; otherwise, the heating element continues to work. This avoids high temperature from damaging the molecular structure of the high-strength adhesive, ensuring that the test block and the standard part can be firmly bonded. Under intelligent control, this device is more convenient to use. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an intelligent carbon fiber bonding strength tester.

[0030] Example 1:

[0031] Combination Figure 1-4 As shown, the present invention provides an intelligent carbon fiber bonding strength tester, including a testing mechanism 100 and a drying mechanism 200. The testing mechanism 100 includes a support frame 110, a threaded rod 120 that slides through the top of the support frame 110, a tension sensor 130 connected to the bottom end of the threaded rod 120, a sleeve 140 connected to the bottom of the tension sensor 130, a T-shaped rod 150 that rotatably passes through the bottom end of the sleeve 140, a standard part 160 that is screwed to the bottom end of the T-shaped rod 150, a sleeve 170 that fits against the top of the support frame 110 and is screwed to the threaded rod 120, and two guide rods 180 that slide through the top of the support frame 110 and are connected to the threaded rod 120.

[0032] The drying mechanism 200 includes a square tube 210 movably sleeved on the outside of the standard part 160, a plurality of connecting rods 220 connecting the rod sleeve 140 and the square tube 210, a plurality of heating elements 230 installed on the outside of the square tube 210, an air inlet pipe 240 connected and communicating with the square tube 210, and a plurality of guide channels 250 surrounding the outside of the standard part 160 and connected to the square tube 210. The bottom outer edge of the standard part 160 is arc-shaped.

[0033] Furthermore, the sleeve 170 consists of a threaded ring and two levers, which are fixed to both sides of the threaded ring respectively. The levers are inclined, and the shape design of the sleeve 170 makes it easy for the operator to rotate the sleeve 170.

[0034] Furthermore, the guide rod 180 is located on top of the tension sensor 130, and the two guide rods 180 are respectively located on both sides of the threaded rod 120. The top of the guide rod 180 is set in a T shape. The layout design of the guide rod 180 can restrict the movement direction of the threaded rod 120, ensuring that the carbon fiber bonding strength can be achieved smoothly. At the same time, its shape design can also prevent the guide rod 180 from falling off the threaded rod 120.

[0035] Furthermore, the air intake pipe 240 slides through the top of the support frame 110, the flow guide channel 250 is connected to the inside of the square tube 210, and the bottom end of the flow guide channel 250 extends to the bottom of the arc surface. The layout design of the flow guide channel 250 enables the hot air to accurately act on the high-strength adhesive and improve the drying time of the high-strength adhesive.

[0036] Furthermore, the standard part 160 is provided with a plurality of reinforcing ribs 500, which are made of metal material. The presence of reinforcing ribs 500 can improve the structural strength of the standard part 160 and reduce the probability of it being damaged during tensile operations.

[0037] Example 2:

[0038] Combination Figure 1-3 As shown, based on Embodiment 1, the bottom end of the rotating sleeve 170 is movably engaged with the housing 300, and the bottom of the housing 300 is fixedly connected to the top of the support frame 110. The housing 300 can limit the rotation of the rotating sleeve 170, making its rotation more stable.

[0039] Example 3:

[0040] Combination Figure 1 As shown in the above embodiment, a temperature sensor 400 is embedded in the top of the support frame 110. The temperature sensor 400 is located near one end of the support frame 110, and the test end of the temperature sensor 400 is located inside the square tube 210. Multiple heating elements 230 are connected in series. The heating elements 230 and the temperature sensor 400 are electrically connected to an external PLC. By setting the temperature sensor 400, the temperature inside the square tube 210 can be measured in real time, keeping the temperature inside the square tube 210 below 50°C to avoid high temperature damaging the molecular structure of the high-strength adhesive. Then, the detection data of the temperature sensor 400 is transmitted to the external PLC in real time. When the temperature exceeds 50°C, the external PLC shuts down the heating elements 230, thereby realizing intelligent control and making the device more convenient to use.

[0041] The working principle and usage process of this utility model are as follows: A square or circular test block of a specified size is cut out from the central area of ​​a large-volume carbon fiber substrate. A high-strength adhesive is uniformly coated on the surface of the test block and the bottom of the standard part 160. Then, with the support 110 in close contact with the substrate, the standard part 160 is bonded to the test block. Next, multiple heating elements 230 are turned on and gas is injected into the air inlet pipe 240. After the gas enters the square tube 210, it is indirectly heated by the heating elements 230. The resulting hot air enters the interior of the arc surface through the guide channel 250 and acts on the high-strength adhesive between the standard part 160 and the test block. This process can significantly shorten the curing time of the adhesive, thereby reducing the single test cycle, avoiding sample accumulation, and improving the overall test efficiency.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
