Description

Technical Field

[0001] This utility model relates to the field of LCD and OLED screen processing technology, specifically to a screen bezel pull-out force testing device. Background Technology

[0002] In the production and processing of LCD and OLED screens, the screen bezel usually needs to be coated with a damming adhesive and cured to achieve the sealing, waterproofing and structural reinforcement of the screen. The adhesion of the damming adhesive directly affects the screen's service life and performance stability.

[0003] Currently, the devices used in the industry to test the pull-out force of dam adhesive have many shortcomings:

[0004] Firstly, most jigs are fixed structures, which cannot be adapted to screens of different sizes and thicknesses, resulting in poor adaptability.

[0005] Secondly, the low precision of the tension drive mechanism makes it difficult to achieve uniform and stable tension output, resulting in large fluctuations in test data.

[0006] Third, the screen fixing method is rudimentary, and the screen is prone to shifting during the test, which affects the accuracy of the test results;

[0007] These problems mean that existing testing equipment cannot reliably guarantee the quality of screen production, and there is an urgent need for a pull-out force testing device that is highly adaptable, has high testing accuracy, and is stable in operation. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a screen frame pull-out force testing device to solve the problems of poor adaptability and unstable fixation of the existing device.

[0009] To solve the above-mentioned technical problems, this utility model provides the following solution: A screen frame pull-out force testing device of this utility model includes a base plate and further includes:

[0010] A fixture support is provided at one end of the base plate surface;

[0011] A fixture detachably mounted on the upper end of the fixture bracket, the fixture having a groove surface;

[0012] A pressure block detachably mounted to the fixture; the pressure block spans the groove surface;

[0013] A linear drive module is mounted on the base plate and has a guide rail mounted on a guide rail seat, a movable plate slidably connected to the guide rail, and a power source that drives the movable plate to perform linear motion.

[0014] A pressure gauge is installed on the movable plate. The pressure gauge is equipped with a pull rod. The outer end of the pull rod is provided with a hook and the pull rod is oriented towards the fixture. The pull rod moves with the pressure gauge and its movement trajectory can reach above the groove surface.

[0015] Furthermore, the height of the fixture support is adjustable.

[0016] Furthermore, the linear drive module includes either a synchronous belt screw module or a linear motor module.

[0017] Furthermore, the power source of the synchronous belt lead screw module is an electric motor, which drives the lead screw through a synchronous belt pulley set. The lead screw is rotatably mounted in the guide rail seat, and a nut is screwed onto the lead screw. The nut is connected to the movable plate through a nut seat.

[0018] Furthermore, the depth of the groove surface is sufficient for the dammed adhesive of the product to protrude from the groove opening.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The screen frame pull-out force testing device of this utility model has strong adaptability: both the fixture and the pressure block adopt a detachable design, which can be quickly replaced according to different sizes and models of screens.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Example 1: The specific structure of this utility model is as follows:

[0033] Please refer to the appendix. Figure 1-3 The present invention provides a screen frame pull-out force testing device, including a base plate 8, and the screen frame pull-out force testing device further includes:

[0034] Fixture bracket 7 is located at one end of the surface of the base plate 8;

[0035] A fixture 1 is detachably mounted on the upper end of the fixture bracket 7, and the fixture 1 has a groove surface;

[0036] A pressure block 2 is detachably mounted on the fixture 1; the pressure block 2 spans the groove surface;

[0037] A linear drive module 6 is mounted on the base plate 8 and has a guide rail 62 mounted on the guide rail seat, a movable plate 63 slidably connected to the guide rail 62, and a power source 61 that drives the movable plate 63 to perform linear motion.

[0038] The pressure gauge 5 is mounted on the movable plate 63 via the mounting part 4. The pressure gauge 5 is equipped with a pull rod 3. The outer end of the pull rod 3 is provided with a hook and the pull rod 3 is oriented towards the fixture 1. The pull rod 3 moves with the pressure gauge 5 and its movement trajectory can reach above the groove surface.

[0039] The height of the fixture support 7 is adjustable.

[0040] The linear drive module 6 includes either a synchronous belt screw module or a linear motor module.

[0041] The power source 61 of the synchronous belt lead screw module is an electric motor. The motor drives the lead screw through a synchronous belt pulley set. The lead screw is rotatably mounted in the guide rail seat. A nut is screwed onto the lead screw, and the nut is connected to the movable plate 63 through a nut seat.

[0042] The depth of the groove surface is sufficient for the product's retaining adhesive 9 to protrude from the groove opening, such as... Figure 2 As shown, Figure 2 for Figure 1 Enlarged view of part A. The dam adhesive 9 is higher than the fixture platform 11.

[0043] Example 2:

[0044] The following is the testing principle of the screen bezel pull-out force testing device of this utility model:

[0045] Fixture 1 is fixed to the upper end of fixture bracket 7 with screws. The height of fixture 1 is adjusted by adjusting the oblong hole on fixture bracket 7, with the oblong hole facing up and down.

[0046] After fixture 1 is fixed, the display screen with applied and cured glue is placed into the groove surface and limited by pressure block 2. Pressure block 2 also serves to prevent the display screen from detaching from the groove surface during testing. Figure 2 As shown, after the glue cures, it forms a dammed adhesive 9, which protrudes from the fixture table surface 11.

[0047] like Figure 3 As shown, the pull rod 3 on the pressure gauge 5 is first manually lifted, and then the movable plate 63 is driven by the linear drive module 6 to move towards the fixture, so that the outer end of the pull rod 3 passes through the dammed rubber 9 (such as...). Figure 4 (As shown).

[0048] Then, the hook is placed on the pull rod 3. After the hook falls down, it can hook the dam adhesive 9. The linear drive module 6 drives the movable plate 63 to move away from the fixture. Since the hook of the pull rod 3 hooks the dam adhesive 9, the pressure gauge 5 starts to test the tension.

[0049] The pressure gauge 5 of this utility model has an accuracy of 0.1N, which can ensure the accuracy of the tensile force test. After the preset test time, the test is stopped. After the pull rod 3 is manually lifted, the pull rod 3 is driven to reset.

[0050] In summary, the screen frame pull-out force testing device of this utility model has strong adaptability: both the fixture and the pressure block adopt a detachable design, which can be quickly replaced according to different screen sizes and models. At the same time, the height of the fixture support is adjustable to adapt to a variety of testing scenarios.

[0051] This utility model screen frame pull-out force testing device has high testing accuracy: it adopts a pressure gauge with an accuracy of 0.1N, and is equipped with a synchronous belt screw module or a linear motor module to achieve uniform and stable pull-out force output and reduce test data fluctuations.

[0052] This utility model screen frame pull-out force testing device operates stably: the pressure block crosses the groove surface to press the screen tightly, preventing the screen from shifting during the test; the pull rod hook design can reliably hook the surrounding adhesive, ensuring the stability of the test process.

[0053] This utility model screen frame pull-out force testing device is easy to operate: the linear drive module realizes the automatic movement and reset of the movable plate, the testing process is simple, and the difficulty of manual operation is reduced.

[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
