[0002] Paint adhesion testing is a key step in evaluating coating quality, and the grid knife test is a commonly used method. This method involves using a grid knife to create a grid of small squares on the coating surface, which are then adhered with tape to assess the coating's adhesion. However, traditional grid knives present several significant problems and limitations in practice. Firstly, there's the issue of operating force. Using a grid knife typically requires considerable force, which not only increases the difficulty but can also lead to inaccurate test results. Secondly, there's the issue of line straightness. Lines drawn with a handheld grid knife are often not straight enough, which affects the regularity of the small squares and, in turn, the accuracy of the adhesion test.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it designate a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 The present embodiment provides a paint adhesion test auxiliary tool, including a connecting component 100 and a scribing component 200. The connecting component 100 and the scribing component 200 are used in conjunction with each other to solve the problems existing in the existing use of a grid knife for paint adhesion testing, such as the large force required for scribing, the laborious operation, the difficulty in accurately controlling the straightness of the scribing, the reliance on the tester's feel, the need to adjust the direction of the coating plate when scribing, and the low test efficiency.

[0028] Specifically, the connection assembly 100 includes an operating table 101 and an adjusting member 102. The adjusting member 102 is movably connected to the operating table 101. The coating plate to be tested is mounted on the adjusting member 102. The direction of the coating plate on the operating table 101 can be changed according to the size and shape of the coating plate.

[0029] The marking assembly 200 includes a control member 201 and a marking member 202. The control member 201 is movably connected to the operating table 101, and the marking member 202 is movably connected to the control member 201. The control member 201 can be displaced on the operating table 101 according to the set direction, accurately grasping the straightness, and can also control parameters such as the depth of contact between the marking member 202 and the coated plate and the distance of the marking on the coated plate. The marking member 202 is mainly used for gridding the coated plate to facilitate subsequent adhesion testing with tape.

[0030] By setting up the operating table 101 and the adjustment part 102, the original idea of ​​using a grid knife to directly adjust the direction angle of the coating plate is changed. Instead, the adjustment part 102 is used to perform precise angle and direction adjustments to ensure that the grid is uniform in area. This also avoids the subsequent problem of different grid sizes affecting the test accuracy. The control part 201 controls the marking part 202, making the straight line marking action precise and able to control the force during marking, thereby improving the accuracy of the test and improving the efficiency of the test.

[0031] Example 2

[0032] Reference Figure 1-4 , this embodiment is based on the previous embodiment.

[0033] Specifically, the adjustment member 102 includes a mounting plate 102a and a fixing pin 102b. The mounting plate 102a is rotatably connected to the mounting seat 101a on one side of the operating table 101 and is auxiliary equipped with a rotating bearing to provide a labor-saving effect during rotation. The fixing pin 102b is provided on the mounting plate 102a and is movably connected to the mounting plate 102a. It can be plugged in and out of the mounting plate 102a. One end of the fixing pin 102b passes through the mounting plate 102a and is inserted into the fixing hole 101a-1 on the mounting seat 101a to connect, so that the mounting plate 102a cannot rotate.

[0034] Furthermore, a slide groove 101a-2 is provided on the side wall of the mounting seat 101a, and a fixing hole 101a-1 is provided in the slide groove 101a-2, and a number of fixing holes 101a-1 are provided according to the test requirements. In this embodiment, four fixing holes 101a-1 are provided to provide the mounting plate 102a with rotation angles of 90°, 180°, 270°, and 360°. Different angles can also be set according to the test requirements.

[0035] During use, if the tester slightly pulls up the fixing pin 102b so that its bottom end is out of the fixing hole 101a-1, the mounting plate 102a can be rotated. After being inserted into the fixing hole 101a-1, the mounting plate 102a cannot be rotated, which makes it convenient to rotate the direction of the coating plate to draw the grid.

[0036] Furthermore, the adjustment member further includes a mounting pin 102c, which is connected to a plurality of mounting holes 102a-1 provided on the side wall of the mounting plate 102a. In order to achieve the installation limit of the coating plate, the mounting pin 102c is provided in a plurality of numbers and is fixedly connected to the mounting hole 102a-1 through a thread.

[0037] When in use, the test coating plate is placed on the upper side of the mounting plate 102a. According to the size, shape and other parameters of the coating plate, several mounting pins 102c are inserted into the mounting holes 102a-1 to limit the coating plate, and then the next operation can be carried out.

[0038] In summary, this embodiment provides a convenient and effective adjustment structure for the adhesion grid test of the coated plate, so that the rotation angle after one stroke can be accurately controlled and the area size of subsequent grids can be kept uniform, which provides convenience for testers.

[0039] Example 3

[0040] Reference Figure 1-4 , this embodiment is based on the previous two embodiments.

[0041] Specifically, the control component 201 includes a displacement block 201a and a pressing frame 201b. The displacement block 201a is movably connected to the displacement rod 101b on one side of the operating table 101, so that the displacement component 201a performs linear displacement in the groove in the displacement rod 101b, ensuring the straightness when marking. The pressing frame 201b is fixedly connected to the side wall of the displacement block 201a, and the pressing frame 201b is driven by the displacement block 201a to perform accurate linear displacement.

[0042] Furthermore, the marking member 202 includes a telescopic rod 202a and a marking head 202b. One end of the telescopic rod 202a is movably connected to the displacement block 201a, that is, it can penetrate the displacement block 201a and extend and retract up and down to achieve distance control from the coating plate. The other end of the telescopic rod 202a is connected to the marking head 202b for marking the coating plate.

[0043] As a preferred solution, the number of blades of the scribing tool head 202b can be increased or replaced according to test requirements.

[0044] As another preferred solution, the marking blade 202b can be an existing grid knife that is fixedly connected to the telescopic rod 202a through a fixed structure for testing.

[0045] Furthermore, the side wall of the telescopic rod 202a is rotatably connected to the pressing rod 201b-1 on the inner side of the pressing frame 201b, and the pressing rod 201b-1 is rotatably connected to the connecting rod on the pressing frame 201b, and a handle 201b-2 is provided at the end of the pressing rod 201b-1 away from the telescopic rod 202a, and the handle 201b-2 is fixedly connected to the pressing rod 201b-1. The tester operates the handle up and down to realize the rotation of the pressing rod 201b-1 around the connecting rod, and at the same time controls the telescopic rod 202a to move up and down at the other end, thereby achieving the up and down distance control of the marking head 202b.

[0046] In summary, when in use, the tester first installs the coating plate on the mounting disk 102a, then selects a suitable marking blade 202b, and controls the telescopic rod 202a to press downward against the coating plate by lifting the pressing rod 201b-1. After reaching the downward pressure distance required for the test, the handle 201b-2 is pushed or pulled along the direction of the displacement rod 101b to mark a straight line on the coating plate. After one completion, the handle 201b-2 is pressed downward to separate the marking blade 202b from the coating plate, and the fixing pin 102b is slightly pulled out. The mounting disk 102a is rotated at an angle of 90°, and the fixing pin 102b is loosened so that it is inserted into the fixing hole 101a-1. The above marking action is repeated to obtain a grid with uniform area size. The coating plate is then removed and the adhesion test can be performed with tape. This auxiliary tool is not only easy to use, but also can improve the accuracy and efficiency of the test.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
