Description

Technical Field

[0001] This utility model relates to the field of ink adhesion testing, and in particular to a vacuum adsorption universal 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applied for a patent for a fixture for cross-cut adhesion testing (application number 2024229357571, which is currently unpublished and referred to as Scheme 1).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.

This improves operational efficiency, extends service life, and significantly reduces material waste.

[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 structure of the vacuum adsorption universal fixture for cross-cut adhesion testing according to this utility model. Figure 2This is an exploded view of the universal vacuum adsorption fixture for cross-cut adhesion testing according to this invention. This embodiment of the universal vacuum adsorption fixture for cross-cut adhesion testing is used to detect the ink adhesion effect on the surface of glass products of electronic devices, including but not limited to mobile phones. The fixture includes a vacuum adsorption base 1 and a test plate 2.

[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 The vacuum adsorption base 1 is roughly a rectangular block, and it is made of bakelite material. The long side of the test plate 2 is parallel to the long side of the test plate 2. When the test plate 2 is flipped over and placed on the vacuum adsorption base 1, the short side of the test plate 2 is parallel to the short side of the test plate 2.

[0031] The upper surface of the vacuum adsorption base 1 is recessed to form a vacuum adsorption groove 101 for adsorbing and positioning the product to be tested. Theoretically, the vacuum adsorption groove 101 only needs to be located in the area below the glass product to be tested, and its shape and pattern are not limited. However, considering that the product will be scratched during testing and the pressure of the scratching is required, as well as the weight of the product on the adsorption force, the vacuum adsorption groove 101 in this embodiment includes an annular shallow groove and a dividing groove. The annular shallow groove and the dividing groove are slightly recessed by 4mm relative to the upper surface of the vacuum adsorption base 1. The center of the annular shallow groove coincides with the center of the upper surface of the vacuum adsorption base 1. The outline size of the annular shallow groove is slightly smaller than the outline size of the smallest product to be tested. The dividing groove is located in the area enclosed by the annular shallow groove and its two ends are connected to the annular shallow groove. The dividing groove is a straight groove that passes through the center of the upper surface of the vacuum adsorption base 1. The extension direction of the straight groove is parallel to the wide side of the vacuum adsorption base 1 and perpendicular to the flipping center of the test plate 2. The straight groove divides the area enclosed by the annular shallow groove into two equal areas. In this embodiment, when the test plate 2 is flipped onto the vacuum adsorption base 1, four types of test grooves 201 extending in the first direction and four types of test grooves 201 extending in the second direction are distributed on both sides of the straight groove.

[0032] The vacuum adsorption base 1 has a vacuum adsorption hole 102 for connecting to a vacuum device, and the vacuum adsorption hole 102 extends to communicate with the vacuum adsorption groove 101. The vacuum adsorption hole 102 includes a first adsorption hole and a second adsorption hole. The first adsorption hole extends horizontally, with one end extending to the long / short side of the vacuum adsorption base 1, and the other end extending directly below the annular shallow groove / segmented groove and communicating with the annular shallow groove through the second adsorption hole. The second adsorption hole can extend obliquely or vertically. In this embodiment, the first adsorption hole extends along the length of the vacuum adsorption base 1 to the short side, and the second adsorption hole extends vertically, i.e., along the thickness of the vacuum adsorption base 1.

[0033] One side of the test plate 2 is flip-connected to the vacuum adsorption base 1 and can be flipped over to cover the product under test. Specifically, a swing rod 3 is installed on the long side of the vacuum adsorption base 1, and the test plate 2 is flip-connected to the vacuum adsorption base 1 via the swing rod 3. More specifically, refer to... Figure 3-4The vacuum adsorption base 1 has a set of fixed ears 103 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 103. For example, both the fixed ears 103 and the ends of the swing rod 4 have through holes, and a rotating shaft passes through these holes to connect the fixed ears 103 and the swing rod 4 in series. The swing rod 4 has a slot 301 that runs through its length along its axial direction. The test plate 2 is inserted into the slot 301 and locked with screws.

[0034] The assembly of the fixture of this utility model is relatively simple: the test plate 2 is placed in the slot 301 of the swing rod 4 and the screws are tightened. Then the swing rod 4 is inserted between a set of fixing ears 103 of the vacuum adsorption base 1, and the two ends of the swing rod 4 are connected to the set of fixing ears 103 through a rotating shaft. In this way, the test plate 2 and the vacuum adsorption base 1 are connected as one unit. Finally, the connector of the vacuum equipment is inserted into the vacuum adsorption hole 102.

[0035] Use of the fixture of this utility model:

[0036] 1) During production, the operator takes the glass product to be tested, places it on the upper surface of the vacuum adsorption base 1, starts the vacuum equipment to start evacuating the vacuum, and the product to be tested is adsorbed and fixed.

[0037] 2) Rotate the test plate 2 over the glass product to be tested to achieve alignment;

[0038] 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.

[0039] In summary, during testing, this invention only requires placing the product on the upper surface of the vacuum adsorption base, then activating the vacuum equipment to evacuate and fix the product in place. The test plate can then be flipped on to perform the test. This invention not only avoids the risks of misalignment / slippage during testing, greatly facilitating manual operation and ensuring 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. This improves operational efficiency, extends service life, and significantly reduces material waste. Furthermore, the multiple test grooves are available in various specifications according to different widths, further enhancing versatility and convenience.
