Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0045] References to "embodiments" in this document mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0046] In the prior art, making a carbon fiber spline into a carbon fiber multifilament specimen is achieved by manual gluing. Since the placement of the carbon fiber spline and the gluing process are manually performed, problems such as inaccurate placement of the carbon fiber spline and non-standard gluing may occur due to human operation differences. When the gluing is not standard, the glue in the gluing area of the reinforcing patch may be uneven. When the placement position of the carbon fiber spline is inaccurate, the length of each carbon fiber spline in the gluing area and the reinforcing patch may be different, which will affect the effectiveness of the carbon fiber multifilament specimen and lead to inaccurate test results.

[0047] The following will further describe the embodiments of the present utility model in conjunction with Figures 1 to 8 the following.

[0048] To solve the above technical problems, as Figures 1 to 3 shown, an exemplary embodiment of the present utility model provides a specimen preparation device for tensile testing. The specimen preparation device includes a support member 10, a first card slot plate 20, a second card slot plate 30, a support plate 40, and a gluing plate 50. The first card slot plate 20 is connected to the first end of the support member 10, and the first card slot plate 20 is provided with at least one first card slot 21. The second card slot plate 30 is connected to the second end of the support member 10, and the second card slot plate 30 is provided with at least one second card slot 31. The first card slot 21 and the second card slot 31 are arranged side by side in the first direction. The first card slot 21 is used to position the first end of the carbon fiber spline, and the second card slot 31 is used to position the second end of the carbon fiber spline. The support plate 40 is supported on the support member 10, and the support plate 40 is used to support the reinforcing patch and the carbon fiber spline. The gluing plate 50 is used to cover the carbon fiber spline on the support plate 40. The gluing plate 50 is provided with a plurality of gluing through holes 51, and the positions of the gluing through holes 51 correspond to the positions of the reinforcing patches.

[0049] In this embodiment, the sample preparation device for tensile testing includes a support member, a first slot plate, a second slot plate, a support plate, and a glue application plate. The support member is connected between the first slot plate and the second slot plate. The support plate is supported on the support member, and the glue application plate is used to cover the carbon fiber spline on the support plate. The first end and the second end of the carbon fiber spline are positioned through the first slot and the second slot respectively, and the reinforcing sheet and the carbon fiber spline are supported by the support plate and the support member to limit the carbon fiber spline at the target position, improving the accuracy of the placement position of the carbon fiber spline. Glue is applied to the carbon fiber spline through the glue application through-holes of the glue application plate, improving the standardization and uniformity of glue application. By improving the accuracy of the placement position of the carbon fiber spline and the standardization of glue application, the effectiveness of the carbon fiber multifilament specimen is improved, thereby improving the accuracy of the test results.

[0050] Exemplarily, the support plate 40 can be an adhesive plate, and the reinforcing sheet can be kraft paper, cardboard, cardboard, etc. The reinforcing sheet can be adhered to the adhesive plate with tape to fix the reinforcing sheet. Fixing the reinforcing sheet through the adhesive plate can further improve the accuracy of the placement position of the carbon fiber spline, thereby improving the accuracy of the test results.

[0051] Exemplarily, the reinforcing sheet includes a first reinforcing sheet and a second reinforcing sheet. The first reinforcing sheet is adhered to one side of the support plate 40 close to the first slot plate 20, and the second reinforcing sheet is adhered to one side of the support plate 40 close to the second slot plate 30. The first reinforcing sheet and the second reinforcing sheet are arranged side by side in the first direction. The first end of the carbon fiber spline formed by impregnating and curing the carbon fiber multifilament is placed in the first slot 21 of the first slot plate 20, and the second end is placed in the second slot 31 of the second slot plate 30, so that the length of each carbon fiber spline between the first reinforcing sheet and the second reinforcing sheet is the same. Then, the glue application plate 50 is covered on the carbon fiber spline of the support plate 40, and glue is applied to the first end and the second end of the carbon fiber spline respectively through the multiple glue application through-holes 51 of the glue application plate 50, improving the uniformity of glue application, so that the length of each carbon fiber spline in the glue application area is the same, thereby improving the effectiveness of the carbon fiber multifilament specimen.

[0052] Exemplarily, glue (such as epoxy resin) can be evenly applied on the glue application plate 50 by using an item such as a scraper, so that the glue can be evenly applied to the first end and the second end of the carbon fiber spline through the glue application through-holes 51.

[0053] Exemplarily, the glue application through-holes 51 of the glue application plate 50 extend in the first direction, and the width of the glue application through-holes 51 in the first direction is smaller than the width of the reinforcing sheet in the first direction.

[0054] In one embodiment, as Figures 1 to 5As shown, the first card slot plate 20 is provided with at least one row of first card slots 21, and a plurality of first card slots 21 in the same row are arranged at intervals in the second direction. The second card slot plate 30 is provided with at least one row of second card slots 31, and a plurality of second card slots 31 in the same row are arranged at intervals in the second direction. Among them, each first card slot 21 corresponds to each corresponding second card slot 31 in the first direction, and the first direction is perpendicular to the second direction.

[0055] In this embodiment, since at least one row of first card slots and second card slots are respectively provided on the first card slot plate and the second card slot, by providing a plurality of first card slots and second card slots, multiple carbon fiber splines can be made into carbon fiber multifilament specimens. Since the carbon fiber multifilament specimen contains multiple carbon fiber splines, the reliability of the test results is improved during the subsequent tensile test. Moreover, since each first card slot and second card slot correspond to each other in the first direction, the straightened state of each carbon fiber spline is the same during the specimen preparation process, thereby improving the reliability of the carbon fiber multifilament specimen.

[0056] Exemplarily, in the first direction, each first card slot 21 and each second card slot 31 respectively correspond to an adhesive application through hole 51.

[0057] Exemplarily, as Figure 1 and Figure 2 shown, in the first direction, the first edge and the second edge of the adhesive application plate 50 are correspondingly arranged. In the first direction, each first card slot 21 corresponds to an adhesive application through hole 51, and the adhesive application through hole 51 is arranged on one side of the adhesive application plate 50 close to the first edge. Each second card slot 31 corresponds to an adhesive application through hole 51, and the adhesive application through hole 51 is arranged on one side of the adhesive application plate 50 close to the second edge. Since the two ends of the carbon fiber spline need to be adhered to the reinforcing sheet, by arranging the adhesive application through holes 51 on one side of the adhesive application plate 50 close to the first edge and one side close to the second edge respectively, the adhesive application efficiency can be improved while the adhesive application cost can be saved.

[0058] Exemplarily, the number of the first card slots 21 and the second card slots 31 can both be 4, 8, 10, 12, 16, 20, 24, etc.

[0059] In one embodiment, as Figure 1 shown, the support member 10 includes a support rod 11. The first end of the support rod 11 is connected to the first card slot plate 20, and the second end of the support rod 11 is connected to the second card slot plate 30. The support rod 11 is used to support the carbon fiber spline.

[0060] In this embodiment, by reusing the support rod, it can not only connect the first card slot plate and the second card slot plate to improve the integrity of the specimen preparation device and facilitate the movement of the specimen preparation device, but also support the carbon fiber spline to improve the reliability of the specimen preparation device. Moreover, since the structure of the support rod is simple, the complexity of the structure of the specimen preparation device is reduced.

[0061] In one embodiment, as Figure 1 shown, a plurality of support rods 11 are provided. The first ends of the plurality of support rods 11 are all connected to the first slot plate 20, and the second ends of the plurality of support rods 11 are all connected to the second slot plate 30. Among them, the support rods 11 are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction.

[0062] In this embodiment, by providing a plurality of support rods, the first slot plate and the second slot plate can be reliably connected. At the same time, the carbon fiber spline is supported and strengthened by the plurality of support rods, improving the stability of the carbon fiber spline during the sample preparation process. In addition, by vertically connecting the support rods to the first slot plate and the second slot plate, the stability of the sample preparation device is improved.

[0063] Exemplarily, the number of the support rods 11 can be 2, 3, 4, 5, 6, etc.

[0064] In one embodiment, as Figure 6 shown, the support rod 11 includes a first connecting rod 111, a first limiting structure 112, and a second limiting structure (not shown in the figure). The first limiting structure 112 is connected to the first end of the first connecting rod 111. The second limiting structure is connected to the second end of the first connecting rod 111. The first limiting structure 112 is connected to the first slot plate 20, and the second limiting structure is connected to the second slot plate 30.

[0065] In this embodiment, the first connecting rod can be fixed between the first slot plate and the second slot plate through the first limiting structure and the second limiting structure, improving the stability of the first connecting rod and thus improving the reliability of the sample preparation device.

[0066] In one embodiment, as Figures 1 to 6 shown, the first limiting structure 112 includes a first through hole 1121, the first slot plate 20 includes a second through hole 22, and the first through hole 1121 and the second through hole 22 are connected by a first fastener. The second limiting structure includes a third through hole, the second slot plate 30 includes a fourth through hole 32, and the third through hole and the fourth through hole 32 are connected by a second fastener.

[0067] In this embodiment, the first through hole and the second through hole are connected by the first fastener to fixedly connect the first connecting rod and the first slot plate, and the third through hole and the fourth through hole are connected by the second fastener to fixedly connect the first connecting rod and the second slot plate. Since the structure of the fastener is simple and the cost is low, and the process of setting the through holes is also relatively simple and the cost is low, the first connecting rod is fixed between the first slot plate and the second slot plate by connecting the through holes with the fasteners, reducing the complexity of the sample preparation device and the manufacturing cost of the sample preparation device at the same time.

[0068] Illustratively, the first fastener and the second fastener may be pins, screws, etc.

[0069] Exemplarily, the second through hole 22 is located at a position of the first slot plate 20 close to the first slot 21, and the fourth through hole 32 is located at a position of the second slot plate 30 close to the second slot 31. Since the first end and the second end of the carbon fiber spline supported by the first support rod 11 are respectively located in the first slot 21 and the second slot 31. The middle part of the carbon fiber spline and the first end and the second end can be kept in a horizontal state on the support plate 40 by the second through hole 22 and the fourth through hole 32 close to the first slot 21 and the second slot 31, thereby improving the reliability of sample preparation.

[0070] In one embodiment, if Figure 6 As shown, the first connecting rod 111 includes a middle section 1111 and limiting sections 1112 arranged at both ends of the middle section 1111 . The diameter of the limiting section 1112 is larger than the diameter of the middle section 1111 , and the support plate 40 is clamped between the two limiting sections 1112 .

[0071] In this embodiment, since the first connecting rod includes a middle section and a limiting section, the support plate is clamped between the two limiting sections, which can improve the stability of the support plate to improve the stability of the carbon fiber spline located on the support plate during the glue coating process, thereby improving the effectiveness of the carbon fiber multifilament sample.

[0072] In one embodiment, if Figure 7 As shown, the support component 10 further includes a second connecting rod 12, a first end of the second connecting rod 12 is connected to the first card slot plate 20, a second end of the second connecting rod 12 is connected to the second card slot plate 30, and the second connecting rod 12 is used to connect the first card slot plate 20 and the second card slot plate 30. The second connecting rod 12 is located on the side of the support rod 11 away from the first card slot 21.

[0073] In this embodiment, by positioning the second connecting rod on the side of the support rod away from the first slot, the support rod and the second connecting rod can respectively support the top and bottom of the first slot plate and the second slot plate, thereby improving the stability of the sample preparation device. In addition, due to the simple structure of the second connecting rod, the complexity of the structure of the sample preparation device is reduced.

[0074] For example, Figures 1 to 7 As shown, the two ends of the second connecting rod 12 include a fifth through hole 121 and a sixth through hole (not shown in the figure), respectively, the first slot plate 20 includes a seventh through hole 23, and the second slot plate 30 includes an eighth through hole 33. The fifth through hole 121 and the seventh through hole 23 are connected by a third fastener, and the sixth through hole and the eighth through hole 33 are connected by a fourth fastener.

[0075] In one embodiment, a plurality of second connecting rods 12 are provided.

[0076] In this embodiment, by providing a plurality of second connecting rods, the reliability of the connection between the first clamping groove plate and the second clamping groove plate can be improved. Moreover, by arranging the second connecting rods and the first connecting rods at intervals and alternately in the second direction, the stability of the sample preparation device is improved by connecting different positions of the first clamping groove plate and the second clamping groove plate through the first connecting rods and the second connecting rods.

[0077] Exemplarily, the number of the second connecting rods 12 can be 2, 3, 4, 5, 6, etc.

[0078] In one embodiment, as Figure 1 and Figure 8 shown, the sample preparation device further includes a limiting plate 60. The limiting plate 60 is connected to the first end of the first clamping groove plate 20 and the first end of the second clamping groove plate 30, and the limiting plate 60 is used to limit the glue spreading plate 50.

[0079] In this embodiment, the glue spreading through hole can be limited at the target glue spreading position by limiting the glue spreading plate with the limiting plate, thereby improving the accuracy of glue spreading. Moreover, during the glue spreading process, the excess glue can also flow out from the second end of the first clamping groove plate and the second end of the second clamping groove plate, so as to be collected and recycled.

[0080] Exemplarily, the limiting plate respectively includes a ninth through hole 61 and a tenth through hole 62. The first clamping groove plate 20 includes an eleventh through hole 24, and the second clamping groove plate 30 includes a twelfth through hole 34. The ninth through hole 61 and the eleventh through hole 24 are connected by a fifth fastener, and the tenth through hole 62 and the twelfth through hole 34 are connected by a sixth fastener.

Each first slot 21 corresponds to a corresponding second slot 31 in the first direction, and the first direction is perpendicular to the second direction. The first ends of the three support rods 11 are respectively connected to the first slot plate 20 through the first through holes 1121 of the first limiting structure 112, the second through holes 22 of the first slot plate 20, and the first fasteners.
