[0031] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0032] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.
[0033] like Figure 1 As shown, the first exemplary embodiment of the present application provides a positioning fixture for a pulling head, the positioning fixture 1 includes a supporting transverse plate 101, a vertical adjustment device 102 and a clamping matching structure 103, wherein the supporting transverse plate 101 is suspended and can move laterally; the vertical adjustment device 102 is vertically connected to the supporting transverse plate 101, and the bottom of the vertical adjustment device 102 is used to connect the pulling head 2 to drive the pulling head 2 to move vertically; the clamping matching structure 103 includes two clamping vertical plates 1031, and the two clamping vertical plates 1031 can adjust the lateral spacing between each other to clamp the substrate 3.
[0034] Specifically, in Figure 1In the illustrated embodiment, the support transverse plate 101 can be suspended above the substrate 3 and the drawing head 2 with the support of two clamping vertical plates 1031, the support transverse plate 101 can move relative to the clamping vertical plates 1031, and the vertical adjustment device 102 can be fixedly connected to the drawing head 2, so that when the support transverse plate 101 moves in the transverse direction, the vertical adjustment device 102 and the drawing head 2 can be driven to move synchronously, and after stopping the movement, the drawing head 2 can be positioned at the specified position.
[0035] It can be seen that when the positioning fixture 1 of this exemplary embodiment is used to position the pulling head 2, the two clamping vertical plates 1031 can be adjusted to clamp the substrate 3 first, so as to form a preliminary positioning and ensure the stability of the fixture as a whole. By adjusting the supporting horizontal plate 101 in the horizontal direction, the pulling head 2 can be moved to the middle position of the substrate 3, and then the vertical adjustment device 102 is used to drive the pulling head 2 to move vertically, so as to adjust the distance between the pulling head 2 and the substrate 3, thereby effectively controlling the thickness of the adhesive between the pulling head 2 and the substrate 3. Overall, the pulling head can be supported by the positioning fixture of this exemplary embodiment. It can be maintained in the pasting position for a long time and stably, effectively solving the problem of the slippage of the pulling head 2 while waiting for the adhesive to solidify, thereby ensuring that the subsequent coating adhesion test has higher accuracy.
[0036] In an optional or preferred embodiment, the clamping matching structure 103 further includes a connecting structure 1032 , and the supporting horizontal plate 101 forms a laterally movable connection with the clamping vertical plate 1031 via the connecting structure 1032 .
[0037] Specifically, Figure 1 In the embodiment shown, the connection structure 1032 includes an upper groove plate 10321 and a lower groove plate 10322 which are arranged parallel to each other and spaced apart. The upper groove plate 10321 and the lower groove plate 10322 are both connected to the inner side wall of the clamping vertical plate 1031 along the horizontal extension. The upper groove plate 10321, the lower groove plate 10322 and the clamping vertical plate 1031 jointly enclose a plug-in slot for the support horizontal plate 101 to be plugged in. On the one hand, the two clamping vertical plates 1031 respectively support the support horizontal plate 101, the vertical adjustment device 102 and the pulling head 2 connected to the vertical adjustment device 102 through the two plug-in slots; on the other hand, by providing the two plug-in slots, sufficient moving space can be provided for the support horizontal plate 101, so that the horizontal movement of the support horizontal plate 101 can be realized, and vice versa, the horizontal spacing between the two clamping vertical plates 1031 can be adjusted. The versatility is very strong and it can be applied to the clamping of substrates 3 of different sizes.
[0038] In an optional or preferred embodiment, referring to Figure 1The top surface of the supporting cross plate 101 is provided with a relatively raised cross plate floating point 1011. Therefore, when the supporting cross plate 101 is plugged into the plug-in slot, the cross plate floating point 1011 contacts the bottom surface of the upper slot plate 10321, which can increase the friction between the supporting cross plate 101 and the upper slot plate 10321, ensuring that the supporting cross plate 101 can be tightly connected to the connecting structure 1032 after stopping moving and is not easy to separate, thereby ensuring that the pulling head 2 will not deviate during pasting, and the stability is higher.
[0039] In some other embodiments, the bottom surface of the supporting horizontal plate 101 may also be provided with the above-mentioned horizontal plate floating point 1011, which can also play a role in increasing the friction between the supporting horizontal plate 101 and the connecting structure 1032.
[0040] Furthermore, in some implementations, at least one of the bottom surface of the upper slot plate 10321 and the top surface of the lower slot plate 10322 may be provided with a relatively raised slot plate floating point, wherein the cross plate floating point 1011 and the slot plate floating point can engage with each other, thereby further enhancing the friction between the supporting cross plate 101 and the connecting structure 1032, and thereby improving the connection stability between the supporting cross plate 101 and the connecting structure 1032.
[0041] It should be noted that the horizontal plate floating point 1011 can be made of the same material as the supporting horizontal plate 101, such as metal material, or non-metallic materials such as rubber and nylon with a relatively higher friction coefficient, which is not limited in this exemplary embodiment. The same is true for the slot plate floating point, which will not be described here.
[0042] In one embodiment, the connection structure 1032 is a snap-fit connection structure, and the support horizontal plate 101 is fixedly connected to the clamping vertical plate 1031 through the snap-fit connection structure. The snap-fit connection structure can be a spring snap, a buckle snap, a magnetic snap, etc. It should be noted that the snap-fit connection structure for realizing the support horizontal plate 101 and the clamping vertical plate 1031 is well known to those skilled in the art, and does not belong to the core improvement part of the present application, so it will not be described here.
[0043] exist Figure 1 In the illustrated embodiment, the vertical adjustment device 102 includes a bolt 1021 for being screwed to the drawing head 2, and the supporting cross plate 101 is formed with a cross plate screw hole for the bolt 1021 to pass through. Therefore, when the bolt 1021 is passed through the supporting cross plate 101 through the cross plate screw hole and the drawing head 2 is screwed to the bottom end of the bolt 1021, the drawing head 2 can be synchronously moved vertically by rotating the bolt 1021, so that the distance between the drawing head 2 and the substrate 3 can be adjusted. It can be seen that the vertical adjustment device 102 using the bolt 1021 is simple in structure, durable, highly reliable and has lower cost.
[0044] In other embodiments, the vertical adjustment device 102 may also be a linear telescopic device. Specifically, the linear telescopic device includes a cylinder and a telescopic rod telescopically connected to the cylinder and having a telescopic end, wherein the cylinder may be fixed to the bottom of the supporting horizontal plate 101, and the telescopic end of the telescopic rod is connected to the drawing head 2, thereby, the telescopic rod is driven by the cylinder to move vertically, thereby driving the drawing head 2 to move synchronously. The linear telescopic device may be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc., which is not limited in this exemplary embodiment.
[0045] The second exemplary embodiment of the present application provides a coating bonding strength detection device, which includes a pulling head 2, a substrate 3 and the above-mentioned positioning tool for the pulling head. Obviously, the coating bonding strength detection device has all the technical effects brought by the above-mentioned positioning tool for the pulling head, so it will not be repeated here.
