Description
Technical Field
[0001] This utility model relates to the field of ink adhesion testing, and in particular to a universal slider clamping 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 applicant previously applied for a patent for a fixture for cross-cut adhesion testing (application number 2024229357571, which is currently unpublished and referred to as Scheme 1). The main idea of Scheme 1 is as follows: the fixture includes a cross-cut base, a cross-cut test plate, and a test base. Multiple test grooves are formed through the cross-cut test plate. The test base has recessed grooves that mimic the shape of the product under test for positioning. The test base is slidably mounted on the cross-cut base and locked in place by locking components. One side of the cross-cut test plate is flipped and connected to the cross-cut base, and can be flipped to cover the test base and the product under test. During later use, it was found that Scheme 1 has the problem that the test base needs to be replaced for products of different sizes, making it unsuitable for various product sizes, and its versatility needs improvement.

[0025] To address the shortcomings of existing technologies that rely heavily on manual placement and alignment of test pieces, leading to significant human error and risks of misalignment or slippage during testing, thus greatly affecting the accuracy of test results, this invention proposes a universal slider-type fixture for cross-cut adhesion testing. This fixture is used to inspect the ink adhesion effect on the surface of glass products in electronic devices. The fixture comprises a base, a test plate, and multiple sliders. Multiple test grooves are formed through the test plate, and multiple horizontal linear grooves corresponding to the sliders are formed on the base. These horizontal linear grooves extend in different horizontal directions, and the sliders are slidably mounted on... The horizontal linear slide groove protrudes from the upper surface of the base. Multiple sliders clamp the product to be tested placed on the upper surface of the base by sliding together, and then lock it in place by locking components. One side of the test plate is flipped and connected to the base and can be flipped to cover the product to be tested. In this way, the present invention can not only avoid the risk of misalignment / slippage during the test, greatly facilitate manual operation and ensure the accuracy of test results, but also realize the testing of glass products of different sizes, achieving the purpose of being universal for most products of different sizes / shapes. It can improve operating efficiency, service life and greatly reduce material loss.
[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 , Figure 1 This is a schematic diagram of the universal slider clamping fixture for cross-cut adhesion testing according to this utility model. Figure 2This is an exploded view of the universal slider clamping fixture for cross-cut adhesion testing according to this utility model. The universal slider clamping fixture for cross-cut adhesion testing in this embodiment is used to test the ink adhesion effect on the surface of glass products of electronic devices, including but not limited to mobile phones. The fixture includes a base 1, a test plate 2, and multiple sliders 3.
[0028] The test board 2 is roughly a rectangular plate made of stainless steel. Multiple test grooves 201 are formed along the entire thickness of the test board 2. To improve versatility, the multiple test grooves 201 are available in various widths. More specifically, in this embodiment, which is applied to mobile phone glass cover applications, there are four widths: 1.0mm, 1.5mm, 2.0mm, and 3.0mm.
[0029] Each specification includes two sets of test slots 201 extending in opposite directions. Specifically, in each specification, one set of test slots 201 extends along a first direction and is evenly spaced along a second direction, while the other set extends along the second direction and is evenly spaced along the first direction. The first direction refers to the direction parallel to the flip center of the test plate 2, and the second direction is perpendicular to the first direction. In this embodiment, the first direction is the direction of the long side of the test plate 2, and the second direction is the direction of the short side of the test plate 2.
[0030] refer to Figure 3 , Figure 3 This is a structural schematic diagram of the base. The base 1 is roughly a rectangular block, and the base 1 is made of bakelite material. The long side of the test plate 2 is parallel to the long side of the test plate 3. When the test plate 2 is flipped over and placed on the base 1, the short side of the test plate 2 is parallel to the short side of the test plate 3.
[0031] The base 1 has multiple horizontal linear grooves 101 corresponding to multiple sliders 3, and the sliders 3 are slidably mounted in the corresponding horizontal linear grooves 101. The multiple horizontal linear grooves 101 extend in different horizontal directions. In this embodiment, there are four sliders 3, so there are also four horizontal linear grooves 101, which are divided into two groups. One group of horizontal linear grooves 101 is parallel to the long side of the base 1, that is, parallel to the flipping center of the test plate 2, and the other group of horizontal linear grooves 101 is parallel to the wide side of the base 1. Each group of horizontal linear grooves 101 is composed of two horizontal linear grooves 101 that are arranged opposite each other. That is to say, in this embodiment, the four horizontal linear grooves 101 extend vertically from the middle position of the four sides of the base 1 in a direction pointing towards the center of the base 1. Thus, a set of sliders 3 corresponding to one set of horizontal linear slides 101 can move towards each other along the length direction of the base 1 to adaptively clamp the length dimension of the product to be tested, or move away from each other along the length direction of the base 1 to release the clamping in the length direction of the product to be tested; a set of sliders 3 corresponding to another set of horizontal linear slides 101 can move towards each other along the width direction of the base 1 to adaptively clamp the width dimension of the product to be tested, or move away from each other along the width direction of the base 1 to release the clamping in the width direction of the product to be tested.
[0032] The slider 3 is slidably mounted on the corresponding horizontal linear groove 101 and protrudes from the upper surface of the base 1, so the slider 3 can contact the wide or long side of the product to be tested to achieve abutment. In this embodiment, the four sliders 3 together clamp the four sides of the product to be tested placed on the upper surface of the base 1 and are then locked and positioned by locking components.
[0033] Specifically, in this embodiment, the locking element is a screw, which presses the slider 3 onto the base 1 to achieve locking. Figure 1-2 The screw was not slid out. In this embodiment, the horizontal linear slide 101 runs vertically through the base 1, so a nut is provided at the bottom of the screw to lock it in place.
[0034] One side of the test plate 2 is foldably connected to the base 1 and can be flipped over to cover the product under test. Specifically, a swing arm 4 is installed on the long side of the base 1, and the test plate 2 is foldably connected to the base 1 via the swing arm 4. More specifically, refer to... Figure 3-4The base 1 has a set of fixed ears 102 facing each other at both ends of its long side. The two ends of the swing rod 4 are rotatably connected to the set of fixed ears 102. For example, both the fixed ears 102 and the ends of the swing rod 4 have through holes, and a rotating shaft passes through these holes to connect the fixed ears 102 and the swing rod 4 in series. The swing rod 4 has a slot 401 that runs through its length along its axial direction. The test plate 2 is inserted into the slot 401 and locked with screws.
[0035] The assembly of the fixture of this utility model mainly includes two aspects:
[0036] First, the test board 2 and the base 1 are assembled: the test board 2 is placed into the slot 401 of the swing rod 4 and the screws are tightened. Then the swing rod 4 is inserted into a set of fixing ears 102 of the base 1, and the two ends of the swing rod 4 are connected to a set of fixing ears 102 through a rotating shaft. In this way, the test board 2 and the base 1 are connected as one unit.
[0037] Second, the assembly of slider 3 and base 1: Slide slider 3 is placed directly into horizontal linear slide 101 from above. The screw passes through the rear end of slider 3 and a nut is installed for pre-tightening. The nut is rotated until the straight edge of the nut is parallel to the straight side wall of the horizontal linear slide 101 (the distance between the two parallel straight edges of the nut is the same as the distance between the straight side walls of the horizontal linear slide 101). Then, the nut is inserted into the horizontal linear slide 101 so that the straight edge of the nut is in surface contact with the straight side wall of the horizontal linear slide 101 and cannot be rotated. The nut and base 1 are placed flat on the horizontal worktable. At this time, slider 3 is not completely locked and can slide.
[0038] Use of the fixture of this utility model:
[0039] 1) During production, the operator takes the glass product to be tested, places it between the four sliders 3 on the upper surface of the base 1, moves the four sliders 3 to clamp the product together, and tightens the screws on the sliders 3 so that the sliders 3 cannot move.
[0040] 2) Rotate the test plate 2 over the glass product to be tested to achieve alignment;
[0041] 3) Press one hand on the test plate 2, and take the corresponding blade with the other hand. Slide the ink area along the test line groove 201 of the test plate 2 to complete the test.
[0042] In summary, the universal slider clamping fixture for cross-cut adhesion testing of this invention has the following beneficial effects: During testing, the product is simply placed on the upper surface of the base, then the slider is slid to hold the product in place, and the locking mechanism is tightened to secure the product. The test plate is then flipped over to perform the test. This invention not only avoids the risk of misalignment / slippage during testing, greatly simplifies manual operation and ensures the accuracy of test results, but also enables testing of glass products of different sizes, achieving universal applicability to most products of different sizes and shapes. It improves operational efficiency, extends service life, and significantly reduces material waste.
