Description

Technical Field

[0001] This invention relates to the field of fiber processing equipment, and more particularly to a sample holder for carbon fiber monofilament samples. Background Technology

[0002] To understand the properties of carbon fiber materials, it is usually necessary to conduct relevant tests on them. To ensure the accuracy of the test results, it is necessary to prepare carbon fiber monofilament samples that meet the test requirements. By using carbon fiber monofilament samples, accurate characteristic data of the fiber materials can be obtained.

[0003] In existing technologies, carbon fiber monofilament samples are typically fabricated on a separate device, then inspected, and finally, qualified samples are transferred to a sample rack for collection and later use. This process of multiple transfers during carbon fiber monofilament sample fabrication is not only inefficient but also increases the risk of fiber damage during transport, raising the overall risk of sample loss. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a sample holder for carbon fiber monofilament samples, comprising: Frame, support structure; Multiple fixing slots are formed on the frame, and the multiple fixing slots are used to fix the fibers; A marking part is provided on the frame, and the marking part is located at the middle position of the fixing groove; A measuring unit is mounted on the frame, with its measuring end adjacent to the marking unit. The plurality of fixing slots are arranged in an array along the length direction of the bracket, and each fixing slot includes: The first groove is formed in the first side wall of the frame; The second groove is formed in the second side wall of the frame, and the first side wall and the second side wall are arranged opposite to each other; The first groove and the second groove are arranged in a one-to-one correspondence, and the depth of the first groove is less than the depth of the second groove.

[0005] In some embodiments, the number of the frame is provided as multiple, and the support further includes: A sliding frame, wherein multiple frame bodies are slidably disposed on the sliding frame; A fixed structure is provided on the frame and the sliding frame, and the fixing buckle fixes the frame to the sliding frame.

[0006] In some embodiments, the fixing structure includes: A fixed boss is provided on the frame; A fixing groove is provided on the sliding frame. When the fixing buckle is in the fixed state, the fixing boss is located in the fixing groove.

[0007] In some embodiments, the opening ends of the first groove and / or the second groove are provided with rounded corner structures.

[0008] In some embodiments, the first groove and the second groove are inclined relative to a preset plane, the first groove and the second groove extend along the height direction of the frame, and the preset plane is a plane perpendicular to the side wall of the frame.

[0009] In some embodiments, the inclination angle between the first tank and the second tank is 2° to 5°.

[0010] In some embodiments, the first and second grooves are triangular in shape.

[0011] In some embodiments, the bracket is marked with a plurality of labels, which correspond one-to-one with the plurality of fixing slots, and the plurality of labels are used to distinguish the plurality of fixing slots.

[0012] In some embodiments, the support is made of kraft paper.

[0013] In some embodiments, the bracket has handles at both ends.

[0014] The beneficial effects of this invention are as follows: By setting the depth of the first tank to be less than that of the second tank, the fiber can be tilted at a certain angle after being placed in the fixed tank.

Furthermore, by providing a marking section, the center position of the fiber can be indicated, ensuring that the liquid resin is dripped onto the center of the fiber. Simultaneously, by defining a measuring section, the size of the formed liquid resin spheres can be directly measured to verify the quality of the produced carbon fiber monofilament sample. This achieves the goal of integrating the functions of carbon fiber monofilament sample production, inspection, and collection onto a single device. Attached Figure Description

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0019] In related technologies, carbon fiber monofilament samples are typically prepared on a separate device, then inspected, and finally transferred to a sample rack for collection and later use. This process of multiple transfers during sample preparation is not only inefficient but also increases the risk of fiber damage during transport, raising the overall risk of sample loss.

[0020] To address the problems existing in related technologies, in an exemplary embodiment of the present invention, a sample holder for carbon fiber monofilament samples is provided, such as... Figure 1 and Figure 2 As shown, the device includes a support, multiple fixing slots 2, a marking section 3, and a measuring section 4. The support serves as the basic support structure for the carbon fiber monofilament sample holder, and its structural stability directly affects the overall performance of the device. The support consists of a frame 1, the shape of which can be arbitrarily set according to actual needs. In this example, the frame 1 is a hollow rectangular structure.

[0021] Multiple fixing slots 2 are formed on the frame 1. These slots 2 are used to fix the carbon fiber monofilament samples 7, and are arranged in an array along the length of the frame. The fixing slots 2 are the core structure for fixing the carbon fiber monofilament samples 7. The array of multiple fixing slots 2 along the length of the frame enables the fixing of a batch of fibers. The spacing between each fixing slot 2 can be arbitrarily set according to the type of carbon fiber monofilament sample 7 to ensure that adjacent samples do not interfere with each other, while maximizing the use of space in the frame 1.

[0022] like Figure 1 As shown, each fixing slot 2 includes a first slot body 21 and a second slot body 22. The first slot body 21 is formed on the first side wall 11 of the frame 1, and the second slot body 22 is formed on the second side wall 12 of the frame 1. The first side wall 11 and the second side wall 12 are arranged opposite to each other. This symmetrical arrangement can fix the fiber from both ends, improving the stability of the fixation. In this example, the first side wall 11 and the second side wall 12 are the side walls corresponding to the two long sides of the hollow rectangular frame 1, respectively. When the fiber is placed in the first slot body 21 and the second slot body 22, the fiber placement direction is parallel to the width direction of the frame 1.

[0023] The first slot 21 and the second slot 22 are set in a one-to-one correspondence, such as Figure 5 As shown, the depth of the first groove 21 is less than the depth of the second groove 22. By setting the depth of the first groove 21 to be less than the depth of the second groove 22, the fiber will be in a tilted state at a certain angle after being placed in the first groove 21 and the second groove 22. In this example, the carbon fiber monofilament sample 7 includes the fiber and liquid resin microspheres 8 agglomerated on the fiber. When making the carbon fiber monofilament sample 7, liquid resin needs to be dripped onto the fiber, and the dripped liquid resin needs to agglomerate into a spherical shape to facilitate subsequent testing. By setting the depth of the first groove 21 to be less than the depth of the second groove 22, the fiber is in a tilted state, which allows the liquid resin dripped onto the fiber to agglomerate under the action of gravity, ultimately forming liquid resin microspheres 8. In addition, since the depth of the first groove 21 is less than the depth of the second groove 22, when placing the fiber, the operator can first place the fiber in the deeper second groove 22 to pre-fix the fiber, and then place the fiber in the first groove 21. When taking the carbon fiber monofilament sample 7 after its preparation, the operator can first take one end of the carbon fiber monofilament sample 7 out of the shallower first groove 21, and then take the other end of the carbon fiber monofilament sample 7 out of the second groove 22, avoiding pulling damage to the carbon fiber monofilament sample 7. This facilitates the placement of the fiber before preparing the carbon fiber monofilament sample 7 and the taking of the prepared carbon fiber monofilament sample 7.

[0024] like Figure 2As shown, the marking part 3 is disposed on the frame 1, and the marking part 3 is located at the middle position of the fixing groove 2. By setting the marking part 3, the middle position of the fixing groove 2 can be marked. The form of the marking part 3 can be arbitrarily set according to the actual situation, for example, it can be set as a raised marking line, a marking line of different colors, etc. The marking part 3 is disposed throughout the entire frame 1 to mark the middle position of each fiber placed in the fixing groove 2. Furthermore, the marking part 3 is located at the middle position of the fixing groove 2, which can accurately correspond to the fiber in each fixing groove 2. When the fiber is placed in the fixing groove 2, the position marked by the marking part 3 is the middle position of the fiber. By setting the marking part 3, the operator can accurately identify the middle position of the fiber. When making carbon fiber monofilament sample 7, the operator can accurately drop liquid resin at the middle position of the fiber, so that the liquid resin microspheres 8 formed by aggregation are all located at the middle position of the fiber. This not only ensures the consistency of the produced carbon fiber monofilament sample 7, but also eliminates the need for the operator to manually find the middle position of each fiber to drop liquid resin, thus improving the production efficiency and pass rate of carbon fiber monofilament sample 7.

[0025] like Figure 2 As shown, the measuring unit 4 is mounted on the frame 1, with its measuring end adjacent to the marking unit 3. The form of the measuring unit 4 can be arbitrarily set according to actual conditions, such as a measuring structure like a ruler. The measuring end of the measuring unit 4 is the end of the ruler with graduations. By arranging the measuring end of the measuring unit 4 adjacent to the marking unit 3, the ruler can accurately measure the structure at the middle position of the fiber. In this example, the size of the formed liquid resin microspheres 8 is measured. After the liquid resin is dropped into the middle position of the fiber, the diameter of the formed liquid resin microspheres 8 can be quickly measured by placing the frame 1 under a microscope using the microscope and the measuring unit 4. If the diameter is unqualified, the liquid resin microspheres 8 can be wiped off before they solidify and remade, further improving the pass rate of the carbon fiber monofilament samples 7 and reducing the number of unqualified carbon fiber monofilament samples 7, thus reducing production costs.

[0026] In one example, the depth difference between the first groove 21 and the second groove 22 can be arbitrarily set according to actual conditions. By changing the depth difference between the first groove 21 and the second groove 22, the tilt angle of the fiber placed in the fixed groove 2, that is, the angle between the fiber and the horizontal plane, can be changed. When the depth difference between the first groove 21 and the second groove 22 is large, the tilt angle of the fiber is large; when the depth difference between the first groove 21 and the second groove 22 is small, the tilt angle of the fiber is small. In this example, the tilt angle of the fiber is related to the material of the liquid resin microspheres 8 in the required carbon fiber monofilament sample 7. When the viscosity of the material required to form the liquid resin microspheres 8 is high, the tilt angle of the fiber can be increased, for example, by setting the tilt angle of the fiber to 5°. This increases the influence of gravity on the dripping liquid resin, allowing the liquid resin to condense into liquid resin microspheres 8 under the influence of gravity. When the viscosity of the material required to form the liquid resin microspheres 8 is low, the tilt angle of the fiber can be decreased, for example, by setting the tilt angle of the fiber to 0.5°. This reduces the influence of gravity on the dripping liquid resin, preventing the liquid resin from sliding off the fiber under the influence of gravity and thus preventing it from condensing into liquid resin microspheres 8.

[0027] In an exemplary embodiment, the opening ends of the first groove 21 and / or the second groove 22 are provided with rounded corner structures (not shown in the figure). When placing or removing the carbon fiber monofilament sample 7, the right-angled edges are prone to friction with the carbon fiber monofilament sample 7, causing damage to the surface of the carbon fiber monofilament sample 7, and even directly affecting the physical properties of the carbon fiber monofilament sample 7, thereby affecting the accuracy of the test results. By setting the rounded corner structure, it is possible to avoid the right-angled edges of the opening ends of the first groove 21 and / or the second groove 22 from causing scratches or wear to the carbon fiber monofilament sample 7, ensuring the integrity of the carbon fiber monofilament sample 7. Furthermore, the rounded corner structure forms a smooth transition surface at the opening ends of the grooves. When placing the carbon fiber monofilament sample 7, the fiber can smoothly slide into the first groove 21 and / or the second groove 22 along the smooth rounded corner surface without the need for precise alignment of the opening, reducing the difficulty of operation; when removing the carbon fiber monofilament sample 7, the smooth rounded corner surface will not obstruct the fiber, avoiding the fiber being caught by the right-angled edges and breaking or being damaged.

[0028] In one exemplary embodiment, such as Figure 1As shown, the first groove 21 and the second groove 22 are inclined relative to a preset plane. The first groove 21 and the second groove 22 extend along the height direction of the frame 1, and the preset plane is a plane perpendicular to the side wall of the frame 1. By setting the first groove 21 and the second groove 22 to have a certain inclination angle, when the carbon fiber monofilament sample 7 is placed in the first groove 21 and the second groove 22, since the first groove 21 and the second groove 22 extend along the height direction of the frame 1, when the carbon fiber monofilament sample 7 has an upward tendency, the side walls of the first groove 21 and the second groove 22 will generate a certain downward pressure on the carbon fiber monofilament sample 7, so that sufficient friction is generated between the side walls of the first groove 21 and the second groove 22 and the carbon fiber monofilament sample 7, ensuring that the carbon fiber monofilament sample 7 can be stably fixed in the first groove 21 and the second groove 22, thereby improving the stability of the placement of the carbon fiber monofilament sample 7. In addition, when it is necessary to remove the carbon fiber monofilament sample 7, the operator can manually apply a force parallel to the extension direction of the first groove 21 and the second groove 22 to the carbon fiber monofilament sample 7, which can easily remove the carbon fiber monofilament sample 7 from the first groove 21 and the second groove 22 without affecting the convenience of using the carbon fiber monofilament sample 7.

[0029] In an exemplary embodiment, the tilt angle of the first groove 21 and the second groove 22 is 2° to 5°. The tilt angle of the first groove 21 and the second groove 22 is the angle between the surface formed by the centerlines of the first groove 21 and the second groove 22 and the preset plane. When the tilt angle is less than 2°, the tilt degree of the first groove 21 and the second groove 22 is too small, and the sidewalls of the first groove 21 and the second groove 22 cannot generate sufficient friction with the carbon fiber monofilament sample 7, resulting in poor fixation and the sample may still shift. At the same time, too small a tilt angle cannot demonstrate the advantages of the tilt setting, and there is little difference from the vertically set groove. When the tilt angle is greater than 5°, the tilt of the first groove 21 and the second groove 22 is too large. The excessive tilt angle will require the operator to adjust the picking angle more carefully when picking up the carbon fiber monofilament sample 7. If it is not picked up along the tilt direction of the first groove 21 and the second groove 22, the excessive tilt angle will cause friction between the first groove 21 and the second groove 22 and the carbon fiber monofilament sample 7 when picking up the carbon fiber monofilament sample 7, which will easily cause damage to the carbon fiber monofilament sample 7.

[0030] In one exemplary embodiment, such as Figure 1As shown, the first groove 21 and the second groove 22 are triangular in shape. The triangular structure has a relatively large opening that gradually tapers towards the bottom. The larger opening allows the carbon fiber monofilament sample 7 to be placed more easily into the first groove 21 and the second groove 22, improving operational efficiency. Furthermore, the larger opening prevents friction between the carbon fiber monofilament sample 7 and the opening of the first groove 21 and the second groove 22 during placement, thus avoiding damage to the carbon fiber monofilament sample 7. Simultaneously, the tapering bottom structure of the triangular structure provides a tight grip on the carbon fiber monofilament sample 7, ensuring precise positioning and effectively preventing displacement within the first groove 21 and the second groove 22, thus improving the reliability of the fixation. Moreover, the gradual taper from the opening to the bottom of the triangular structure allows the first groove 21 and the second groove 22 to adaptably fix carbon fiber monofilament samples 7 of different diameters, improving the applicability of the carbon fiber monofilament sample holder.

[0031] In one exemplary embodiment, the support is marked with multiple labels (not shown in the figure), each label corresponding one-to-one with a plurality of fixing slots 2. These labels are used to distinguish and mark the fixing slots 2. The labels can be set on the support by printing, engraving, or other methods. Each label corresponds to one fixing slot 2. Specifically, the fixing slots 2 can be labeled sequentially according to their arrangement, for example, the first fixing slot 2 corresponds to label 1, the second fixing slot 2 corresponds to label 2, and so on. Alternatively, the fixing slots 2 can be classified and labeled according to their position on the support, such as the first fixing slot 2 of the first frame 1 corresponding to label 1-1, the second fixing slot 2 of the first frame 1 corresponding to label 1-2, the first fixing slot 2 of the second frame 1 corresponding to label 2-1, and so on. By labeling each fixing slot 2, accurate identification and differentiation of the carbon fiber monofilament samples 7 are achieved. When processing carbon fiber monofilament samples 7 in batches, staff can associate the information of each sample with its corresponding label, allowing for quick identification of the sample's identity through the label, avoiding sample confusion, and ensuring the accuracy and traceability of the test data. Furthermore, the clear labeling eliminates the need for staff to verify sample information one by one when picking up or placing samples and recording data. They can quickly complete the operation simply by using the label, greatly shortening the operation time and improving work efficiency.

[0032] In one exemplary embodiment, such as Figure 3 and Figure 4As shown, multiple racks 1 are provided, and the support also includes a sliding frame 5 and a fixing structure. Multiple racks 1 are slidably mounted on the sliding frame 5, and the fixing structure is provided on both the racks 1 and the sliding frame 5 to secure the racks 1 to the sliding frame 5. The method of slidably mounting multiple racks 1 on the sliding frame 5 can be arbitrarily selected, such as by using slide rails. The arrangement of multiple racks 1 allows for the batch storage of carbon fiber monofilament samples 7, enabling different racks 1 to store different types of carbon fiber monofilament samples 7 for different testing items, facilitating sample classification and management. Furthermore, by slidably mounting multiple racks 1 on the sliding frame 5, space utilization can be improved and space occupancy reduced. Specifically, when there are many quantities or types of carbon fiber monofilament samples 7, multiple racks 1 are needed for storage; in this case, multiple racks 1 can be unfolded from the sliding frame 5 for use. When there are fewer quantities or types of carbon fiber monofilament samples 7, the number of racks 1 required is reduced; in this case, multiple racks 1 can be slidably tightened to reduce space occupancy. The fixing structure is set on the frame 1 and the sliding frame 5 to fix the frame 1 on the sliding frame 5, prevent the frame 1 from sliding during storage or transportation, and ensure the stability of the carbon fiber monofilament sample 7.

[0033] In one example, such as Figure 3 and Figure 4 As shown, the sliding frame 5 also has multiple fixing slots 2, the shape and spacing of which are the same as those on the frame 1. When multiple frames 1 are unfolded, the fixing slots 2 on the frame 1 can connect with those on the sliding frame 5 to form a complete array. When multiple frames 1 are retracted, the fixing slots 2 on the sliding frame 5 perfectly overlap with those on the frame 1, allowing the fixing slots 2 in the overlapping portion of the sliding frame 5 and the support to function normally without affecting the number of available fixing slots 2 on the support.

[0034] In one example, such as Figure 3As shown, the sliding frame 5 has one unit, and multiple frame bodies 1 are slidably mounted on the sliding frame 5. When a sample holder for a carbon fiber monofilament sample needs to occupy less space, a scheme in which multiple frame bodies 1 are slidably mounted on the sliding frame 5 can be adopted. When the multiple frame bodies 1 are tightened, the length of the sliding frame 5 is the length of the sample holder for the carbon fiber monofilament sample. In this example, the sliding frame 5 has three frame bodies 1, which are arranged sequentially at both ends and the middle position of the sliding frame 5, and the sliding frame 5 is located inside the three frame bodies 1. When the three frame bodies 1 are tightened on the sliding frame 5, the frame bodies 1 located at both ends move towards the middle position of the sliding frame 5 until they connect with the frame body 1 located in the middle position. The three frame bodies 1 are connected end to end to form an integral structure for fixing the carbon fiber monofilament sample 7. When more or more types of carbon fiber monofilament samples 7 need to be placed, the frames 1 located at both ends of the sliding frame 5 can be pulled outwards. At this time, the size of the sample holder for carbon fiber monofilament samples is the sum of the size of the frames 1 located at both ends of the sliding frame 5 and the size of the sliding frame 5 itself, allowing the sample holder for carbon fiber monofilament samples to hold more or more types of carbon fiber monofilament samples 7. At the same time, the frame 1 located in the middle position of the sliding frame 5 can be adjusted in position according to the types of carbon fiber monofilament samples 7 that need to be placed. For example, when only two types of carbon fiber monofilament samples 7 need to be placed, the frame 1 located in the middle position of the sliding frame 5 can be moved to the two ends of the sliding frame 5, so that the three frames 1 form two parts separated by the sliding frame 5. By placing the two types of carbon fiber monofilament samples 7 in the two parts of the frame 1 respectively, the two types of carbon fiber monofilament samples 7 can be stored separately. When it is necessary to place three types of carbon fiber monofilament samples 7, the frame 1 located in the middle position of the sliding frame 5 can be fixed in the middle position of the sliding frame 5, so that the three frames 1 remain as three unconnected parts. By placing the three types of carbon fiber monofilament samples 7 in the three frames 1 respectively, the three types of carbon fiber monofilament samples 7 can be stored separately.

[0035] In another example, such as Figure 4As shown, multiple sliding frames 5 are provided, with two frame bodies 1 slidably mounted on each sliding frame 5. This arrangement allows for a longer sample holder for carbon fiber monofilament samples, accommodating a greater number and variety of carbon fiber monofilament samples 7. In this example, there are two sliding frames 5 and three frame bodies 1, which are slidably connected by the sliding frames 5 to form a linear sample holder for carbon fiber monofilament samples. When a greater number and variety of carbon fiber monofilament samples 7 are needed, each frame body 1 can be moved to both ends of the sliding frame 5 to obtain a longer sample holder for carbon fiber monofilament samples, accommodating a greater number and variety of carbon fiber monofilament samples 7. When a smaller number and variety of carbon fiber monofilament samples 7 are needed, the three frame bodies 1 can be slid towards the middle of the sliding frame 5, connecting the three frame bodies end to end, shortening the overall length of the sample holder for carbon fiber monofilament samples, thus reducing space occupation.

[0036] In an exemplary embodiment, the fixing structure includes a fixing boss and a fixing groove. The fixing boss is disposed on the frame 1, and the fixing groove is disposed on the sliding frame 5. When the fixing structure is in a fixed state, the fixing boss is located within the fixing groove. The shapes of the fixing boss and the fixing groove are adapted to each other. In this example, the shapes of the fixing boss and the fixing groove are set as spherical protrusions and spherical grooves with curved edges. When it is necessary to release the fixing state of the fixing structure, by applying opposite forces to the frame 1 and the sliding frame 5, the spherical protrusions can slide out along the curved edge of the spherical groove, thereby releasing the fixing state of the fixing structure.

[0037] In one example, multiple fixing structures can be provided, with multiple fixing structures located at different positions on the frame 1 and the sliding frame 5, so that the frame 1 can be fixed at different positions on the sliding frame 5 to adapt to the placement requirements of carbon fiber monofilament samples 7 under different conditions, thereby improving the adaptability of the sample holder for carbon fiber monofilament samples.

[0038] In one exemplary embodiment, the support is made of kraft paper. Because kraft paper has a certain degree of elasticity, it is less likely to damage the carbon fiber monofilament sample 7 while ensuring support. Furthermore, the support made of kraft paper can be folded and stored when not in use. In addition, kraft paper also has advantages such as being environmentally friendly, low-cost, and easy to process.

[0039] In one exemplary embodiment, such as Figure 1 As shown, handles 6 are provided at both ends of the support. The handles 6 are located at both ends of the support, that is, at both ends along the length of the support. The shape of the handles 6 can be arbitrarily set, such as an arc shape, a square shape, etc. By providing handles 6, it is easier for operators to handle the sample holder of the carbon fiber monofilament sample, improving the safety of the carbon fiber monofilament sample 7 during transportation and avoiding damage to the carbon fiber monofilament sample 7 due to collisions, drops, etc.

[0040] In summary, this disclosure achieves this by setting the depth of the first tank 21 to be less than that of the second tank 22, allowing the fiber to be placed at a certain angle in the fixed tank 2. After liquid resin is dripped onto the fiber, the liquid resin can coalesce into spheres under the influence of gravity. Furthermore, the marking section 3 indicates the center position of the fiber, ensuring that the liquid resin is dripped onto the center of the fiber. Simultaneously, the measuring section 4 allows for direct measurement of the size of the formed liquid resin spheres, verifying the quality of the produced carbon fiber monofilament sample 7. This achieves the goal of integrating the functions of producing, inspecting, and collecting carbon fiber monofilament samples 7 onto a single device.
