DETAILED DESCRIPTION
[0030] In order to make the technical personnel in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.
[0031] As Figures 1-5As shown, the carbon fiber bundle tension sample preparation device in the embodiment of the utility model, including sample preparation board 1, sample preparation board 1 is provided with test sample area 2, for placing carbon fiber bundle 7. Two rows of end fixed components 5 are symmetrically arranged at the both ends of sample preparation board 1, and each row of end fixed components 5 is sequentially arranged by multiple groups of first fixed seat 501 and second fixed seat 502. Among them, adjacent first fixed seat 501 and second fixed seat 502 are symmetrically arranged, and sliding groove 505 is formed on the adjacent end face of first fixed seat 501 and second fixed seat 502, and clamping assembly for clamping and fixing the end of carbon fiber bundle 7 is installed in the inside of sliding groove 505.
[0032] As shown in Figure 3 and Figure 4 , the clamping assembly includes a clamping block 503 and an elastic assembly 504. The elastic assembly 504 is fixed at one end to the inner side of the sliding groove 505, and the other end of the elastic assembly 504 is fixed to the clamping block 503. The clamping block 503 is slidingly connected inside the sliding groove 505, that is, the clamping block 503 can elastically stretch and contract inside the sliding groove 505.
[0033] The clamping blocks 503 on the first fixed seat 501 and the second fixed seat 502 are closely arranged and can firmly clamp the ends of the carbon fiber bundle 7. The upper edge line of the closely arranged surface is rounded to facilitate the entry of the carbon fiber bundle 7 between the closely arranged clamping blocks 503, simplifying the operation.
[0034] Preferably, in this embodiment, the clamping block 503 is a rubber clamp block, which can not only prevent the carbon fiber bundle 7 from loosening, but also avoid clamping the ends of the carbon fiber bundle 7.
[0035] Specifically, the two ends of the carbon fiber bundle 7 are inserted between the closely arranged clamping blocks 503 from the rounded corner and straightened. At this time, under the push of the elastic assembly 504, the two clamping blocks 503 clamp and fix the two ends of the straightened carbon fiber bundle 7, thereby avoiding the carbon fiber bundle 7 from winding and loosening.
[0036] As shown in Figure 1 and Figure 2 , two rows of reinforcing sheet grooves 3 are symmetrically arranged on the sample preparation board 1. The inside of the reinforcing sheet groove 3 is used to place the posted reinforcing sheet 6 and collect excess glue liquid when gluing.
[0037] The length, width and depth of the inside of the reinforcing sheet groove 3 are respectively 1mm more than the length, width and depth of the reinforcing sheet 6, which ensures that there is a gap between the reinforcing sheet 6 and the inner wall of the reinforcing sheet groove 3, so that the excess glue liquid can flow downward, effectively preventing the excess glue liquid from overflowing, and avoiding the glue liquid from flowing onto the carbon fiber bundle 7 in the test sample area 2.
[0038] Two rows of reinforcing sheet grooves 3 correspond to two rows of end fixing assemblies 5 one by one, so as to paste reinforcing sheets 6 on each group of clamped and fixed carbon fiber filaments 7.
[0039] Two rows of reinforcing sheet grooves 3 are provided with glue residue grooves 4 away from one side of the sample area 2, and the lower end face of the reinforcing sheet groove 3 is inclined towards the glue residue groove 4.
[0040] Preferably, in this embodiment, the depth inside the glue residue groove 4 is greater than the depth inside the reinforcing sheet groove 3, which ensures that the excess glue entering the inside of the glue residue groove 4 can all flow into the inside of the glue residue groove 4.
[0041] Preferably, in this embodiment, the reinforcing sheet groove 3 is arranged close to the glue residue groove 4, and the end of the reinforcing sheet groove 3 close to the glue residue groove 4 is in an open shape, that is, the reinforcing sheet groove 3 and the inside of the glue residue groove 4 are connected with each other, which is convenient for cleaning the glue in the inside of the reinforcing sheet groove 3.
[0042] Preferably, in this embodiment, the glue residue groove 4 is a long straight groove, which is convenient for cleaning the glue in the inside of the glue residue groove 4.
[0043] Working principle:
[0044] When the carbon fiber filament needs to be tested for tensile force, first, the reinforcing sheet 6 is placed in the corresponding reinforcing sheet groove 3, then the carbon fiber filament 7 is placed on the upper end sample area 2 of the sample plate 1, and the two ends of the carbon fiber filament 7 are pulled straight through the close clamping blocks 503, at this time, under the pushing of the elastic assembly 504 in the sliding groove 505, the two groups of clamping blocks 503 clamp and fix the two ends of the straightened carbon fiber filament 7, so as to avoid the carbon fiber filament 7 from being wound and loosened on the sample area 2. Then the glue is applied on the reinforcing sheet 6, since the reinforcing sheet groove 3 to the glue residue groove 4 is provided with an inclination angle of 7°, the direction of the excess glue flow can be effectively controlled, and then another reinforcing sheet 6 is pasted and solidified. Finally, the filament sample is taken out of the two groups of clamping blocks 503, and the glue residue groove 4 is cleaned.
[0045] By using the carbon fiber filament tensile sample preparation device, the test personnel can quickly prepare multiple groups of carbon fiber filament tensile samples with clamping force and without excess glue, then the sample is tested for tensile force by the universal material testing machine, so as to improve the accuracy of the carbon fiber filament tensile test.
[0046] Compared with the prior art, the carbon fiber filament tensile sample prepared by using the carbon fiber filament tensile sample preparation device can avoid the carbon fiber filament from being wound and loosened on the sample area, and at the same time, the carbon fiber filament on the sample area is free of excess glue, so as to improve the accuracy of the carbon fiber filament tensile test, and the device has a simple structure and is convenient to operate.
[0047] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
