[0023] (1) The positioning seat and the pressing assembly are coordinated to ensure that the position and pressure of the test strips are consistent during each sample preparation process, thus avoiding the irregularities caused by traditional manual sample preparation. The mechanized drive device replaces manual operation, improves the efficiency of sample preparation, and reduces the time and energy of manual operation. The fixed positioning seat and the pressing plate design ensure that the overlap area and the applied pressure of each sample are consistent, thereby improving the accuracy and repeatability of the glue shear strength test results.

With this arrangement, the pressing plate can directly apply vertical pressure on the overlapping area, ensuring the uniformity of the glue layer. At the same time, when applying pressure, the pressing plate not only presses the overlapping area, but also presses the end of the second spline located at the second positioning seat, so that the second spline on the second positioning seat and the spline in the overlapping area are subjected to uniform pressure, which can prevent the second spline from warping at the end away from the overlapping area.

[0025] (3) By setting a first heater inside the first positioning seat corresponding to the overlapping area and a second heater inside the pressing plate corresponding to the overlapping area, after the glue between the first and second splines is pressed together to form a certain glue layer by the pressing assembly, the first heater and the second heater can be powered on to heat the first positioning seat and the pressing plate, meeting the heating conditions of 80°C / 4H, so that the glue can be completely cured between the first and second splines, meeting the requirements of spline preparation.

[0026] (4) A plurality of gaskets are detachably provided between the second positioning seat and the bottom plate. By adding gaskets to the bottom surface of the second positioning seat, the spacing between the second strip and the first strip can be increased, thereby adjusting the thickness of the glue. This allows the production of glue shear strength test strips under different glue thickness test conditions, and has strong adaptability.

[0027] (5) By setting a pressure sensor in contact with the rotating joint on the connecting seat, the pressure applied by the clamping member to the spline can be obtained through the pressure sensor, thereby accurately adjusting the glue pressing force, thereby adapting to the production of glue shear strength test strips under different pressure conditions, and having strong adaptability.

DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, combined Figure 2-4 The embodiment of the utility model discloses a tool for manufacturing a glue shear strength test strip, including a base plate 1, a positioning component 2 and a pressing component 3.

[0037] The base plate 1 serves as the basic structure of the entire tooling and provides stable support.

[0038] The positioning assembly 2 includes a first positioning seat 21 and a second positioning seat 22 fixedly mounted on the top surface of the base plate 1. The first positioning seat 21 is located to one side of the second positioning seat 22. The top surface of the first positioning seat 21 is used to position the first spline L1, and the top surface of the second positioning seat 22 is used to position the second spline L2. The height of the first positioning seat 21 is smaller than that of the second positioning seat 22. This arrangement creates a height difference between the first spline L1 and the second spline L2 on a horizontal plane, facilitating the formation of an overlapping area.

[0039] The pressing assembly 3 includes a pressing plate 31 and a driving device 32. The pressing plate 31 is located above the first positioning seat 21 and is used to apply pressure to the overlapping area. The driving device 32 drives the pressing plate 31 to move downward to apply pressure to the overlapping area of ​​the first spline L1 and the second spline L2 extending above the first positioning seat 21, so that the glue forms a glue layer G of a certain thickness between the first spline L1 and the second spline L2 in the overlapping area.

[0040] By coordinating the positioning seat and the pressing assembly 3, the position and pressure of the test strip are ensured to be consistent during each sample preparation process, avoiding the irregularities caused by traditional manual sample preparation; the mechanized drive device 32 replaces manual operation, improves the efficiency of sample preparation, and reduces the time and energy of manual operation; the fixed positioning seat and the pressing plate 31 design ensure that the overlapping area and the applied pressure of each sample are consistent, thereby improving the accuracy and repeatability of the glue shear strength test results; the pressure of the pressing plate 31 can be precisely controlled, so that the thickness of the glue layer G in the overlapping area is consistent, thereby ensuring the reliability and effectiveness of the shear strength test.

[0041] As some preferred embodiments, the top surface of the first positioning seat 21 has a first positioning groove 211 for accurately placing the first strip L1 and fixing it at a predetermined position.

[0042] The top surface of the second positioning seat 22 has a second positioning groove 221 for accommodating the second spline L2. The second positioning groove 221 extends horizontally beyond the outer side of the second positioning seat 22, near the end of the first positioning seat 21. This arrangement ensures that, after the second spline L2 is placed in the second positioning groove 221, one end of the second spline L2 extends beyond the second positioning groove 221, forming an overlapping area with the first spline L1. The end of the second spline L2 extending beyond the second positioning groove 221 is positioned above the first spline L1, forming an overlapping area. This placement creates an overlapping area between the two splines, which is a key area for applying glue.

[0043] In the above embodiment, since the overlapping area of ​​the second spline L2 and the first spline L1 is located on the first positioning seat 21, the force applied by the clamping plate 31 acts on the first positioning seat 21. When the clamping plate 31 applies pressure to the overlapping area through the second spline L2, the end of the second spline L2 away from the overlapping area may warp, which causes the second spline L2 to bend.

[0044] To this end, the solution adopted in this embodiment is: one end of the clamping plate 31 is located above the first positioning seat 21 where the overlapping area is located, and the other end is located above the end of the second positioning seat 22 close to the first positioning seat 21. With this arrangement, the clamping plate 31 can directly apply vertical pressure on the overlapping area, ensuring the uniformity of the glue layer G. At the same time, when applying pressure, the clamping plate 31 not only compresses the overlapping area, but also compresses the end of the second spline L2 located at the second positioning seat 22, so that the second spline L2 on the second positioning seat 22 and the spline in the overlapping area are subjected to uniform pressure, which can prevent the second spline L2 from warping at the end away from the overlapping area.

[0045] The depth of the second positioning groove 221 is less than the thickness of the second spline L2. Therefore, when the pressing plate 31 applies pressure to the end of the second spline L2 on the second positioning seat 22, it can avoid touching the second positioning seat 22, ensuring that the pressure is fully applied to the second spline L2.

[0046] To ensure that the glue can completely cure between the first spline L1 and the second spline L2, this embodiment also provides a first heater 4 and a second heater 5. The first heater 4 is fixedly mounted inside the first positioning seat 21 corresponding to the overlapping region, and the second heater 5 is fixedly mounted inside the pressure plate 31 corresponding to the overlapping region. With this arrangement, after the glue between the first spline L1 and the second spline L2 is pressed together by the pressing assembly 3 to form a certain adhesive layer, the first heater 4 and the second heater 5 can be energized to heat the first positioning seat 21 and the pressure plate 31. Meeting the heating conditions of 80°C / 4 hours, the glue can be completely cured between the first spline L1 and the second spline L2, meeting the requirements for spline preparation. At the same time, this tooling does not need to be placed separately in the heating equipment, saving the transfer operation process, reducing equipment usage costs and reducing production efficiency.

[0047] In order to form glue layers G of different thicknesses between the first spline L1 and the second spline L2, this embodiment further provides a plurality of detachable gaskets 6 between the second positioning seat 22 and the base plate 1. Thus, by adding gaskets 6 to the bottom surface of the second positioning seat 22, the spacing between the second spline L2 and the first spline L1 can be increased, thereby adjusting the thickness of the glue. This allows for the production of glue shear strength test strips under different glue thickness test conditions, and has strong adaptability.

[0048] This embodiment shows a preferred structural mode of the driving device 32. Specifically, the driving device 32 includes a support frame 321 and a lifting module 322. The support frame 321 includes a mounting plate 3211 and a support rod 3212 vertically fixed at the corner of the mounting plate 3211. The lower end of the support rod 3212 is fixedly connected to the base plate 1. The lifting module 322 is arranged on the mounting plate 3211 and is used to drive the clamping plate 31 to move up and down.

[0049] The support frame 321 is configured as a support rod 3212 and a mounting plate 3211 structure, and a large operable space is provided between the mounting plate 3211 and the bottom plate 1, which is convenient for taking and placing samples. When making samples, the space is not restricted.

[0050] This embodiment shows a preferred structural mode of the lifting module 322, which includes a screw rod 3221, a screw rod nut 3222, a rotating joint 3223, a connecting plate 3224 and a guide rod 3225;

[0051] The connecting plate 3224 is fixedly arranged horizontally above the pressing plate 31. Two guide rods 3225 are provided, one at each end of the connecting plate 3224 in the longitudinal direction. One end of the guide rod 3225 is fixedly connected to the connecting plate 3224, and the other end moves vertically upward through the mounting plate 3211 and can move up and down along the mounting plate 3211.

[0052] The screw rod 3221 is vertically located between the two guide rods 3225. One end of the screw rod 3221 is connected to the connecting plate 3224 through the rotating joint 3223, and the other end vertically passes through the mounting plate 3211 and is connected to the screw rod nut 3222 fixedly set on the mounting plate 3211. One end of the screw rod 3221 extending out of the mounting plate 3211 is fixedly connected to the hand wheel 3227.

[0053] By adopting the above technical solution, the screw rod 3221 is driven to rotate by the hand-cranked wheel 3227. Since the screw nut 3222 is fixedly connected to the mounting plate 3211, the screw rod 3221 moves up and down relative to the screw nut 3222. The lower end of the screw rod 3221 is connected to the connecting plate 3224 through the rotating joint 3223. The lower end of the screw rod 3221 is rotatably connected to the rotating joint 3223. It moves up and down while the screw rod 3221 rotates, and drives the connecting plate 3224 to move up and down through the rotating joint 3223. In order to prevent the connecting plate 3224 from rotating, the connecting plate 3224 moves up and down relative to the mounting plate 3211 through the guide rod 3225, so that the connecting plate 3224 drives the clamping plate 31 to move up and down.

[0054] The screw rod lifting structure can ensure the accuracy of the up and down movement of the pressing plate 31, so that the downward pressure of the pressing plate 31 can be accurately controlled.

[0055] In order to facilitate the connection between the rotating joint 3223 and the connecting plate 3224, the lifting module 322 of this embodiment is also provided with a connecting seat 3226, which is fixedly set on the top surface of the connecting plate 3224. One end of the rotating joint 3223 is rotatably connected to the lower end of the screw rod 3221, and the other end is clamped with the connecting seat 3226.

[0056] In order to obtain the clamping force of the clamping member, this embodiment also provides a pressure sensor 7 in contact with the rotating joint 3223 on the connecting seat 3226. Thus, the pressure applied by the clamping member to the spline can be obtained through the pressure sensor 7, thereby accurately adjusting the glue clamping force, thereby adapting to the production of glue shear strength test strips under different pressure conditions, and having strong adaptability.

[0057] Preferably, the mounting plate 3211 is also provided with a linear bearing 3228 connected to the guide rod 3225. Thus, when the connecting plate 3224 moves up and down, it can drive the guide rod 3225 to slide up and down relative to the linear bearing 3228, ensuring that the guide rod 3225 moves more smoothly and reducing the sliding friction between the guide rod 3225 and the mounting plate 3211.

[0058] The working principle of this utility model is:

[0059] First, the first strip L1 is horizontally placed in the first positioning groove 211. Glue is applied to the top surface of the end of the first strip L1 near the second positioning seat 22. Then, the second strip L2 is horizontally placed in the second positioning groove 221, with one end of the second strip L2 extending out of the second positioning groove 221 and placed above the first strip L1, so that the second strip L2 and the first strip L1 form an overlapping area that clamps the glue. The screw rod 3221 is driven to rotate by the hand wheel 3227. The screw rod 3221 rotates and moves downward relative to the screw nut. The connecting plate 3224 is driven downward by the rotating joint 3223. The connecting plate 3224 drives the pressure plate 31 to compress the overlapping area. After the pressure in the impulse area is adjusted, the first positioning seat 21 and the pressure plate 31 are heated by the first heater 4 and the second heater 5 to meet the heating conditions of 80°C / 4H, so that the glue layer G between the first strip L1 and the second strip L2 is completely cured, and the production of the glue shear strength test strip is finally completed.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
