[0044] Existing adhesive strength detection devices cannot detect test components of different sizes, shapes, and thicknesses.
[0045] The present utility model provides an adhesive strength detection device.
[0046] Please refer to Figure 1 In an embodiment of the present utility model, the adhesive strength detection device 100 includes: a mounting base 1, a jaw assembly 2, and a strength detection device 3; the mounting base 1 has a placement area and a first limiting structure 11 is provided corresponding to the placement area, the placement area is for placing the component to be tested, and the first limiting structure 11 is for fixing the first test piece of the component to be tested; the jaw assembly 2 has two jaws 21, and the two jaws 21 have a moving stroke of approaching or separating relatively in a second direction, for clamping the second test piece in the second direction; the jaw 21 further includes a second limiting structure 211, the second limiting structure 211 has a first clamping block 2111 and a second clamping block 2112, the first clamping block 2111 and the second clamping block 2112 have a moving stroke of approaching or separating relatively in a first direction, and the second limiting structures 211 of the two jaws 21 are for jointly clamping the second test piece in the first direction; the strength detection device 3 is arranged between the mounting base 1 and the jaw assembly 2; wherein, the jaw assembly 2 is movably mounted on the mounting base 1 in the first direction; the first direction and the second direction are orthogonally arranged.
[0047] The technical solution of the present utility model is to adopt a placement area provided on the mounting base 1 for placing the component to be tested, and a first limiting structure 11 is provided on the mounting base 1 to fix the first test piece. In addition, the adhesive strength detection device 100 further includes a jaw assembly 2 for clamping the second test piece. The jaw assembly 2 moves in the first direction to separate the second test piece from the first test piece. The strength detection device 3 is arranged between the mounting base 1 and the jaw assembly 2 for detecting the adhesive strength. In order to be applicable to clamping second test pieces of different shapes, sizes, and thicknesses, the jaw assembly has two jaws 21, and the two jaws 21 have a moving stroke of approaching or separating relatively in the second direction, and are abutted against the second test piece in the second direction to clamp the second test piece. In order to facilitate separating the first test piece and the second test piece in the first direction, the jaw 21 further includes a second limiting structure 211, the second limiting structure 211 has a first clamping block 2111 and a second clamping block 2112, the first clamping block 2111 and the second clamping block 2112 have a moving stroke of approaching or separating relatively in the first direction, and the second limiting structures 211 of the two jaws 21 are for jointly clamping the second test piece in the first direction and can clamp second test pieces of different thicknesses.
[0048] In one specific embodiment, to enable the two jaws 21 to move in the second direction, the jaw assembly 2 includes: a cross beam 22 extending along the second direction and having a first sliding groove 221 extending along the second direction; the jaw 21 has a main body portion 212 extending along the first direction, the main body portion 212 has a first end, and a first through hole is provided at the first end; a first bolt assembly passes through the first through hole and the first sliding groove 221 to clamp and fix the jaw 21 to the cross beam 22; wherein, loosening the first bolt assembly enables the jaw 21 to slide, and when it slides to the position where it abuts against the second test piece, the first bolt assembly is tightened to fix the jaw 21. The reason for using manual adjustment instead of automatic adjustment is that the external dimensions of the second test piece may vary, and the two jaws 21 may not be able to abut against the surface of the second test piece simultaneously. Moreover, the movement of the jaw 21 in the second direction is to abut against the side of the second test piece, facilitating the second limiting structure 211 to pick up the second test piece from the first direction.
[0049] In one specific embodiment, to enable the second limiting structure 211 to pick up the second test piece from the first direction, the second limiting structure 211 is arranged at the second end. The first clamping block 2111 is fixedly installed on the main body portion 212. The main body portion 212 also has a second end away from the first end, and the main body portion 212 is provided with a second sliding groove 2121 extending along the first direction to enable the second clamping block 2112 to slide along the first direction; the second clamping block 2112 is provided with a second through hole; a second bolt assembly passes through the second through hole and the second sliding groove 2121 to clamp the second test piece. (The first direction, the second direction, and the third direction are mutually orthogonal.) The second clamping block 2112 also slides or fixes the second clamping block 2112 by loosening and tightening the second bolt assembly. Among them, the first clamping block 2111 is fixedly arranged on the side of the second sliding groove 2121 away from the cross beam 22. During the process of the second test piece moving away from the first test piece, the first clamping block 2111 applies force to the second test piece, and the function of the second clamping block 2112 is to prevent the second test piece from suddenly bouncing off due to inertia, so as to avoid hurting surrounding personnel. The first clamping block 2111 extends along the third direction. On the one hand, it is to increase the contact surface and reduce the pressure, reducing the possibility of damaging the second test piece. On the other hand, a length scale can be set.
[0050] To enable the first limiting structure 11 to fix first test pieces with different shapes, sizes, and thicknesses. In one specific embodiment, there are two first limiting structures 11, which are arranged opposite to each other along the third direction to fix the first test piece. The mounting base 1 includes a mounting base main body 12, and the mounting base main body 12 is recessed towards the first direction to form two side walls 121 arranged opposite to each other in the third direction. The mounting base main body 12 also includes a box body 122 located between the two side walls 121; the two first limiting structures 11 are respectively arranged on the two side walls 121.
[0051] The first limiting structure 11 includes: a third sliding groove 111 extending in the first direction, a third clamping block 112 is installed on the side wall 121, a fourth clamping block 113 is provided with a third through hole, and a third bolt assembly passes through the third through hole and the third sliding groove 111 to fix the fourth clamping block 113 to the side wall 121. Loosen or tighten the third bolt assembly to adjust the position of the fourth clamping block 113 so as to jointly clamp first test pieces of different thicknesses with the third clamping block 112. Among them, the third clamping block 112 is arranged on one side of the third sliding groove 111 close to the box body 122.
[0052] During the process of the second test piece moving away from the first test piece, the third clamping block 112 applies a force to the first test piece to prevent the first test piece from moving in the first direction. The function of the fourth clamping block 113 is to prevent the first test piece from suddenly bouncing off due to inertia, so as to avoid hurting surrounding personnel. The third clamping block 112 extends in the second direction. On the one hand, it is to increase the contact area and reduce the pressure, reducing the possibility of damaging the first test piece. On the other hand, length scales can be set.
[0053] Since the first limiting structure 11 is arranged on the two side walls 121, the first test piece may be too large in size and cannot just abut against the two side walls 121, and there may be a situation where the first test piece cannot be placed. Therefore, a fourth through hole is provided on the side wall 121, and the fourth through hole is located between the third clamping block 112 and the fourth clamping block 113 for the first test piece to pass through. In this way, there will be no problem that the first test piece cannot be placed in the placement area.
[0054] In order to know the bonding strength per unit area, length scales are arranged on both the first clamping block 2111 and the third clamping block 112 along their respective extending directions. According to the scales on the two clamping blocks, the widths of the first test piece and the second test piece can be read out. The two widths are multiplied to obtain the bonding area. Then, the bonding strength is obtained according to the strength detection device 3, and then divided by the bonding area to obtain the bonding strength per unit area.
[0055] In order to realize the movement of the jaw assembly 2 in the first direction to separate the second test piece from the first test piece, the bonding strength detection device 100 further includes: a rack 4 and a gear 5; the rack 4 extends in the first direction and is in transmission connection with the jaw assembly 2; the gear 5 is rotatably arranged in the box body 122 and meshes with the rack 4. The gear 5 rotates to move the rack 4 in the first direction. In order to increase the torque so that the user can use less force to separate the second test piece from the first test piece, a worm gear 6 and a worm 7 mechanism are also provided. The worm gear 6 is coaxially arranged and fixedly connected with the gear 5; the worm 7 meshes with the worm gear. Among them, the worm gear and the worm 7 are arranged in the box body 122.
[0056] For the convenience of users, the bonding strength detection device 100 further includes a rocker 8, which is fixedly connected to the worm 7 and extends outside the box body 122.
[0057] In addition, in order to obtain the pulling force indication of the separation of the second test piece from the first test piece, the strength detection device 3 includes a tension sensor 31, which is arranged between the rack 4 and the jaw assembly 2; the bonding strength detection device 100 further includes a display screen 9, which is installed outside the mounting seat 1 and is communicatively connected to the tension sensor 31. The user can read the indication through the display screen 9.
[0058] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
