Description
Technical Field
[0001] This utility model relates to the field of ink adhesion testing, and in particular to a fixture for cross-cut adhesion testing. Background Technology
[0002] Currently, products such as mobile phone glass front and back covers, watch lenses, and films all require pad printing ink. To effectively test the adhesion of the ink to the smooth surface of mobile phone glass and ensure that the ink adheres firmly to the glass, thereby guaranteeing the display effect and durability of the mobile phone screen, a 100-cross pattern test is necessary. The current industry standard for this test involves manually placing the test piece flat on a table, simultaneously using the left hand to hold the cross-cut test strip, aligning it with the ink area, pressing it in place, and using a standard blade in the right hand to cross-cut the ink. Because the current cross-cut test involves manual placement and alignment, the process is highly susceptible to human error, with risks of misalignment or slippage during testing, significantly impacting the accuracy of the results.
[0003] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0025] In view of the shortcomings of existing technologies, which involve manual placement and alignment of the test pieces, the testing process is heavily influenced by human factors, and there is a risk of misalignment or slippage during the test, which greatly affects the accuracy of the test results. This utility model proposes to construct a fixture for the 100-grid test to detect the ink adhesion effect on the surface of mobile phone glass. The general idea is that the fixture includes a grid base, a grid test plate, and a test base. Multiple test grooves are formed through the grid test plate. The test base has recessed grooves that mimic the shape of the object to be tested, used for positioning the object. The test base is slidably mounted on the grid base and locked in place by locking components. Thus, the test base is a detachable, independent structure, allowing testing of objects of different sizes by replacing it. One side of the grid test plate is flipped and connected to the grid base, and can be flipped over to cover the test base and the object to be tested. Therefore, during testing, this invention only requires selecting a suitable test base to position the object, sliding the test base onto the grid base and locking it in place, then flipping over to cover the grid test plate to perform the test. The entire fixture is assembled as a single unit, avoiding the risk of misalignment or slippage during testing, achieving a foolproof design, greatly facilitating manual operation, and ensuring the accuracy of test results.
[0026] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. It should be understood that the embodiments of this utility model and the specific features thereof are detailed descriptions of the technical solutions of this application, and not limitations thereof. Where there is no conflict, the embodiments of this utility model and the technical features thereof can be combined with each other.
[0027] refer to Figure 1-2 The fixture for the cross-cut test of this utility model includes a cross-cut base 1, a cross-cut test plate 2, a test base 3, and a swing rod 4. The test base 3 is slidably mounted on the cross-cut base 1 and locked by a locking member. One side of the cross-cut test plate 2 is flipped and connected to the cross-cut base 1 via the swing rod 4.
[0028] The base 1, swing rod 4, and test base 3 are made of bakelite, while the test plate 2 is made of stainless steel.
[0029] refer to Figure 4The test base 3 is a roughly rectangular plate structure. Its lower surface contacts and slides against the plane of the grid base 1, and its upper surface is recessed to form a contour groove 31 that conforms to the shape of the object to be tested and is used to position the object. Preferably, the bottom of the contour groove 31 is provided with an anti-slip pad, such as anti-slip leather.
[0030] In this embodiment, the contoured groove 31 perfectly conforms to the shape of the object to be tested, and the depth of the contoured groove 31 is consistent with the thickness of the object to be tested. For example, a 1:1 cavity is milled in the middle of the upper surface of the test base 3 according to the size of the object to be tested, serving as the contoured groove 31. The cross-cut test plate 2 can be flipped over and fitted onto the test base 3 and the object to be tested. Test bases 3 with different contoured grooves 31 can be selected for test objects of different sizes.
[0031] refer to Figure 5 The cross-cut test plate 2 is a stainless steel plate with multiple test grooves 21 running through it, extending through the entire thickness of the plate. These test grooves 21 are divided into two separate groups. One group of test grooves extends along a first direction and is evenly spaced along a second direction; the other group extends along the second direction and is evenly spaced along the first direction. The first direction refers to the direction parallel to the rotation center of the cross-cut test plate 2, which we will temporarily refer to as the front-back direction. The second direction is perpendicular to the first direction, i.e., the left-right direction. It is understood that the specifications of the cross-cut test plate 2 may vary depending on the specific product testing requirements.
[0032] When the locking element is unlocked, the test base 3 can slide relative to the grid base 1, and the sliding direction is parallel to the flip center of the grid test plate 2, i.e., the first direction. (Reference) Figure 3-4 The upper surface of the grid base 1 protrudes to form a first slide rail 11, and the lower surface of the test base 3 is recessed to form a first slide groove 32 that slides smoothly along a first direction and engages with the first slide rail 11. The extension directions of both the first slide rail 11 and the first slide groove 32 are parallel to the first direction. More specifically, the grid base 1 is generally a rectangular plate of a certain thickness. A first slide rail 11 is respectively provided on the left and right sides of the upper surface of the grid base 1, and a first slide groove 32 is respectively provided on the left and right sides of the lower surface of the test base 3. Of course, the number of first slide rails 11 and first slide grooves 32 can be increased. In other embodiments, the positions of the first slide rails 11 and first slide grooves 32 can be interchanged. For example, in other embodiments, a second slide groove can be recessed on the upper surface of the grid base 1, and a second slide rail can protrude on the lower surface of the test base 3 to slide smoothly with the second slide groove.
[0033] In this embodiment, a swing rod 4 parallel to the first slide rail 11 is installed on one side of the first slide rail 11 near the corresponding side. Specifically, the swing rod 4 is installed on the left side of the left first slide rail 11. The 100-grid test plate 2 and the 100-grid base 1 are connected by the swing rod 4 for flipping. Specifically, refer to... Figure 3 The upper surface of the cross-section base 1 has a set of fixed ears 12 protruding from the left side, facing each other. The two ends of the swing rod 4 are rotatably connected to the set of fixed ears 12. For example, both the fixed ears 12 and the ends of the swing rod 4 have through holes, and then the fixed ears 12 and the swing rod 4 are connected in series by a rotating shaft. The swing rod 4 has a through slot 41 along its own axial direction, and the cross-section test plate 2 is inserted into the slot 41 and locked with screws.
[0034] After the test base 3 is slidably assembled onto the grid base 1, it needs to be secured for testing. For this purpose, refer to... Figure 1 A locking hole 33 is provided on the right side of the test base 3 away from the swing rod 4. The locking hole 33 extends into the first slide groove 32 in a direction perpendicular to the first slide groove 32. The locking member is assembled into the locking hole 33 and abuts against the first slide rail 11, thereby locking the test base 3 and the grid base 1. The locking member can be a screw.
[0035] The assembly process of the fixture of this utility model is as follows:
[0036] 1) Select the appropriate size test base 3 according to different projects, place the test base 3 along the first slide rail 11 to the appropriate position, and then tighten the screw in the locking hole 33;
[0037] 2) Place the cross-cut test plate 2 into the slot 41 of the swing rod 4 and tighten the screw. Then, insert the swing rod 4 into a set of fixing ears 12 of the cross-cut base 1. Both ends of the swing rod 4 are connected to the set of fixing ears 12 through a rotating shaft. In this way, the cross-cut test plate 2 and the cross-cut base 1 are connected as one unit.
[0038] Use of the fixture of this utility model:
[0039] 1) During production, the operator takes the test piece with their right hand and places it into the contour groove 31 of the test base 3, pushes the test base 3 with their left hand to move it to the test position of the cross-cut base 1, and tightens the guide rail screw in the locking hole 33 with their right hand to fix the test base 3.
[0040] 2) Simultaneously rotate the 100-cross test plate 2 with your left hand to cover the test piece, achieving alignment;
[0041] 3) Press your left hand on the cross-cut test plate 2, take the blade of the specification with your right hand, and scratch the ink area along the test line groove 21 of the cross-cut test plate 2 to complete the test.
[0042] This invention improves the cross-cut test method, avoiding the risks of misalignment / slippage during testing, achieving a foolproof effect, reducing the influence of human instability, greatly facilitating manual operation, and ensuring the accuracy of test results. The test base 3 for placing the product is movable and positionable, and can be disassembled and replaced according to different types / sizes of products, offering excellent versatility and convenience. The specifications of the cross-cut test plate 2 also vary depending on the product testing requirements; this test plate 2 can also be disassembled and replaced, offering excellent versatility and convenience.
