Description

Technical Field

[0001] This utility model relates to the field of electronic protective film testing technology, and in particular to an electronic protective film heat resistance testing device. Background Technology

[0002] Electronic screen protectors are thin film products used to cover the surface of electronic devices such as mobile phones and computer screens to provide protection or auxiliary functions such as scratch prevention, fingerprint prevention, and blue light protection.

[0003] Under current conditions, a high-temperature resistance testing device for protective films, such as the one disclosed in CN217332255U, is commonly used. This device includes a support rod fixedly connected to the lower end face of a rotating sleeve, and a connector fixedly connected to the lower end face of the support rod, with the connector inserted into the interior of a rectangular groove. This device facilitates uniform heating of the protective film, improving test results. However, the threaded rod screw-type fixing structure requires manual rotation of the threaded rod to clamp and release the protective film, making the operation cumbersome and time-consuming. Each test requires repeated rotation of the threaded rod, hindering rapid clamping and affecting batch testing efficiency. Furthermore, the rectangular column inserted into the rectangular opening for fixing the clamping column does not allow for flexible adjustment of the protective film's planar tension, resulting in uneven tension. Uneven stress during heating can lead to localized deformation or wrinkles, causing inconsistent heating areas. The open testing method allows airflow and ambient temperature changes to carry away heat, resulting in unstable working area temperatures that differ significantly from actual usage conditions, impacting the reliability of the test data. Utility Model Content

[0004] The purpose of this invention is to solve the problem of cumbersome clamping in existing electronic protective film heat resistance testing equipment, and to propose an electronic protective film heat resistance testing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electronic protective film heat resistance testing device includes a workbench, on which a heating plate for testing the protective film body is provided. A slide rod is fixedly installed on the workbench, and two uprights are slidably sleeved on the slide rod. An mounting block is installed on the uprights by fixing bolts. The mounting block is provided with a clamping mechanism for clamping the protective film body. Two symmetrically arranged electric guide rails are provided on the workbench, and the heating plate is disposed on the electric guide rails.

[0007] Preferably, a fixing plate is fixedly installed on the upright, and two hand-tightened bolts for fixing the position of the upright are threadedly connected to the fixing plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 An electronic protective film heat resistance testing device includes a workbench 1, a controller is provided on the workbench 1, and a heating plate 14 for testing the protective film body is provided on the workbench 1. The heating plate 14 can output heat of different temperatures according to the testing requirements to act on the protective film body to achieve heat resistance testing. A slide rod 2 is fixedly installed on the workbench 1, and two uprights 3 are slidably sleeved on the slide rod 2. An installation block 5 is installed on the uprights 3 by fixing bolts.

[0023] The mounting block 5 is equipped with a clamping mechanism for holding the protective film body. The clamping mechanism enables quick clamping and stable fixation of the protective film body without the need for an additional power source. It is easy to operate and can avoid clamping damage. It can also be used in conjunction with the upright 3 to keep the protective film body in a taut state, reducing inspection errors.

[0024] Two symmetrically arranged electric guide rails 13 are provided on the workbench 1. The heating plate 14 is set on the electric guide rails 13. The electric guide rails 13 realize the precise movement of the heating plate 14. The electric guide rails 13 drive the heating plate 14 to move smoothly to the inspection position, ensuring that the heat is accurately applied to the protective film body.

[0025] A fixing plate 4 is fixedly installed on the upright 3, and two hand-tightened bolts for fixing the position of the upright 3 are threaded on the fixing plate 4. Please refer to the instruction manual for details. Figure 2 Once the upright 3 has been moved to the appropriate position, the hand-tightening bolt is rotated so that the end of the hand-tightening bolt comes into close contact with the slide bar 2, thereby fixing the upright 3 stably on the slide bar 2 and preventing the upright 3 from shifting during the inspection process.

[0026] The clamping mechanism includes a support plate 6 fixedly mounted on the mounting block 5, and a fixing rod 7 fixedly mounted in the middle of the support plate 6. The fixing rod 7 is perpendicular to the support plate 6 and provides a stable support fulcrum for the pressure plate 8. The pressure plate 8 is mounted on one end of the fixing rod 7 with a pin, and a clamping plate 9 is fixedly mounted on one end of the pressure plate 8. The clamping plate 9 moves against the support plate 6 and is used to clamp the protective film body. The clamping surfaces of the clamping plate 9 and the support plate 6 are provided with a soft rubber pad, which can enhance the clamping force on the protective film body and prevent damage to the protective film body.

[0027] A guide rod 10 that penetrates the support plate 6 is fixedly installed on the pressure plate 8, and a slider 11 is slidably sleeved on the guide rod 10. The slider 11 cooperates with the guide rod 10 to guide the pressure spring 12 and prevent the pressure spring 12 from deviating when it is under force.

[0028] A pressure spring 12 is welded between the slider 11 and the pressure plate 8 and is located on the guide rod 10. The pressure spring 12 can apply a continuous elastic force to the slider 11 in its natural state, thereby making the pressure plate 8 maintain the clamping force on the protective film body.

[0029] One end of the slider 11 has an arc-shaped structure. The arc-shaped structure design can reduce the frictional resistance between the slider 11 and the support plate 6, making the slider 11 slide more smoothly. The support plate 6 has an elongated guide hole corresponding to the guide rod 10. The width of the guide hole matches the guide rod 10, providing sufficient space for the movement of the guide rod 10, and at the same time playing a limiting role to prevent the guide rod 10 from deviating during the movement.

[0030] The workbench 1 is fitted with heat insulation covers 16 at both ends for heat preservation of the inspection area. The heat insulation covers 16 are made of high temperature resistant and heat preservation material, which can effectively reduce the heat loss in the inspection area. Two symmetrically arranged electric telescopic rods 15 are fixedly installed inside the workbench 1 for driving the opening and closing of the heat insulation covers 16.

[0031] It should be noted that the specific models and specifications of the controller, electric guide rail 13, electric telescopic rod 15, and heating plate 14 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] When it is necessary to inspect the protective film itself;

[0034] Press the end of the pressure plate 8 away from the clamping plate 9, the slider 11 abuts against the support plate 6 and applies pressure to the pressure spring 12, the pressure plate 8 rotates around the pin at one end of the fixed rod 7 as the fulcrum, so that the pressure plate 8 drives the clamping plate 9 away from the surface of the support plate 6.

[0035] Place the protective film body between the support plate 6 and the clamping plate 9, release the pressure plate 8, and the pressure spring 12 applies pressure to the support plate 6 through the slider 11, so that the pressure plate 8 rotates in the opposite direction with the pin at one end of the fixed rod 7 as the fulcrum, and the pressure plate 8 drives the clamping plate 9 to clamp the protective film body.

[0036] Push the upright 3 to slide on the slide bar 2. After the upright 3, which has clamped the protective film body, is moved to a suitable position, rotate the hand-tightening bolt on the fixing plate 4. The hand-tightening bolt abuts against the slide bar 2 to fix the position of the upright 3, so that the protective film body is kept in a taut state.

[0037] The controller controls the electric guide rail 13 to open, and the electric guide rail 13 drives the heating plate 14 to move to the inspection position.

[0038] The controller then controls the electric telescopic rod 15 to open, and the electric telescopic rod 15 drives the heat insulation covers 16 at both ends of the workbench 1 to slide and close, sealing the inspection area. Subsequently, the controller controls the heating plate 14 to open, and the heating plate 14 starts to heat. The heat output by the heating plate 14 acts on the protective film body to test the heat resistance of the protective film body.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
