Technical Field

[0001] This utility model relates to the field of touch display technology, specifically to a pressure resistance testing device for touch display production. Background Technology

[0002] A touch screen is a sensory liquid crystal display device that can receive input signals from touch. When a finger or other object touches the graphic buttons on the screen, the tactile feedback system on the screen drives various connected devices according to a pre-programmed program, thereby replacing mechanical button panels and creating vivid audio-visual effects through the liquid crystal display. However, during the production of flat panel touch screens, it is necessary to perform pressure resistance testing on the flat panel touch screens. Currently, some pressure resistance testing devices on the market are inconvenient and cumbersome to fix, which makes testing inconvenient. Therefore, a pressure resistance testing device for touch screen production is proposed. Utility Model Content

[0020] Example

[0021] In response to the problem that some existing touch screen pressure resistance testing devices on the market are inconvenient and cumbersome to fix, making testing inconvenient.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a pressure resistance testing device for touch screen production, including an operation plate 1. Two fixed rods 2 are fixedly installed inside the operation plate 1. Two sliding sleeves 3 are slidably installed on the outer sides of the two fixed rods 2. Support plates 4 are fixedly installed on the outer sides of the two sliding sleeves 3. A support plate 5 is fixedly installed between the two support plates 4 at the same level. A limiting structure is provided inside the operation plate 1. A fixed plate 13 is fixedly installed on the top of the operation plate 1. A hydraulic cylinder 14 is fixedly installed on the top of the fixed plate 13. A pressure sensor 15 is fixedly connected to the output end of the hydraulic cylinder 14. A pressure plate 16 is fixedly connected to the bottom of the pressure sensor 15. When performing pressure resistance testing on a flat panel touch screen, the support plate 5 is slid according to the size of the flat panel touch screen and placed between the two support plates 5 to clamp the support plates 5. Then, the limiting structure limits and fixes the support plates 5. Then, the hydraulic cylinder 14 is activated, which pushes the pressure plate 16 to press the screen, while the pressure sensor 15 performs the test.

[0023] The limiting structure includes two arc-shaped plates 7, both of which are installed inside the operating plate 1. A rubber pad 8 is fixedly installed on one side of each of the two arc-shaped plates 7, and the rubber pad 8 is located outside the rubber ring 6. A connecting rod 9 is fixedly connected between the two rubber rings 6. A polygonal rod 10 is fixedly installed at one end of the connecting rod 9 and slides through the operating plate 1. A rotating plate 11 is rotatably installed at one end of the polygonal rod 10. Two limiting plates 12 are fixedly installed on the outer side of the rotating plate 11. After the flat panel touch screen is clamped by the support plate 5, the rotating plate 11 is rotated so that one end of the limiting plate 12 on the outer side of the rotating plate 11 is at the bottom of the operating plate 1. The polygonal rod 10 and the connecting rod 9 pull the arc-shaped plate 7 to slide, so that the rubber pad 8 on one side of the arc-shaped plate 7 is in close contact with the sliding sleeve 3, thereby limiting the sliding sleeve 3 and facilitating the support plate 5 to clamp the flat panel touch screen.

[0024] The sliding sleeve 3 has a through hole inside. The sliding sleeve 3 is slidably installed on the outside of the fixed rod 2. The support plate 5 is slidably installed on the top of the operating plate 1 through the sliding sleeve 3.

[0025] The sliding sleeve 3 has a groove inside, and the rubber ring 6 is embedded in the groove to increase the friction between the sliding sleeve 3 and the fixed rod 2.

[0026] A polygonal through hole is provided on one side of the control panel 1. A polygonal rod 10 slides through the polygonal through hole and limits the arc plate 7.

[0027] The fixed rod 2 has a strip groove inside, and the connecting rod 9 passes through the strip groove to fix the two arc plates 7 together.

[0028] The pressure sensor 15 in this application is model JLBU-1. Its structure and operating principle are existing technologies, therefore, its structure and operating principle will not be described in detail here.

[0029] The working principle or structural principle is as follows: When performing pressure resistance testing on a flat panel touch screen, the sliding support plate 5 is placed between two support plates 5 according to the size of the flat panel touch screen, so that the support plates 5 clamp the screen. The rotating plate 11 is rotated so that one end of the limiting plate 12 on the outer side of the rotating plate 11 is aligned with the bottom of the operating plate 1. This causes the arc plate 7 to slide through the polygonal rod 10 and the connecting rod 9, so that the rubber pad 8 on one side of the arc plate 7 is in close contact with the sliding sleeve 3, thereby limiting the sliding sleeve 3 and facilitating the clamping of the flat panel touch screen by the support plate 5. Then, the hydraulic cylinder 14 is activated, which pushes the pressure plate 16 to press the screen, and the pressure sensor 15 detects the pressure.
