Abstract
Description
A pressure testing mechanism for a touch screen Technical Field
[0001] This utility model relates to the field of touch screen testing technology, and in particular to a pressure testing mechanism for touch screens. Background Technology
[0002] A touch screen, also known as a touch panel, is a sensor-type liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display screen.
[0003] In existing technologies, when testing the pressure resistance of a touchscreen panel, the touchscreen panel is typically placed flat on a workbench, and a hydraulic cylinder is used to move the testing equipment downwards. The testing equipment contacts the touchscreen surface, and the pressure is monitored in real time to determine the pressure detection status of the touchscreen. However, due to the uneven structure on the back of the touchscreen, the touchscreen panel is prone to tilting when subjected to force, which reduces the accuracy of the pressure detection.

The fixture plate has a positioning groove for placing the touch screen. A pressure plate is provided above the fixture plate. The pressure plate is connected to the lower side of a hydraulic cylinder. The hydraulic cylinder is fixedly mounted on a bracket. The bracket is fixedly mounted on the rear side of the worktable. A pressure detection sensor is installed at the center of the lower side of the pressure plate. The pressure detection sensor is connected to a controller via a wire, and the controller is connected to a display screen via a wire. The controller is located inside the display screen, and the display screen is fixedly mounted at the front end of the bracket.
[0007] As a further embodiment of this utility model, a guide groove is provided on the workbench, and two guide blocks are slidably connected on the guide groove. The two guide blocks are respectively fixed to the lower side of the left support seat and the right support seat.
[0008] As a further embodiment of this utility model, sliding grooves are provided on the right side of the left support and the left side of the right support, and a protruding strip is slidably connected in the sliding groove. The protruding strip is integrally connected to the left and right ends of the tooling plate.

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0017] Referring to Figures 1-4, the pressure testing mechanism for a touch screen provided in this embodiment of the present invention includes a worktable 1, a left support seat 2 and a right support seat 3 slidably connected on the worktable 1, and a fixture plate 12 slidably connected between the left support seat 2 and the right support seat 3. The fixture plate 12 has a positioning groove 121 for placing the touch screen. A pressure plate 5 is provided above the fixture plate 12. The pressure plate 5 is connected to the lower side of a hydraulic cylinder 7. The hydraulic cylinder 7 is fixedly installed on a bracket 8. The bracket 8 is fixedly installed on the rear side of the worktable 1. A pressure detection sensor 9 is installed at the middle position of the lower side of the pressure plate 5. The pressure detection sensor 9 is connected to a controller through a wire, and the controller is connected to a display screen 6 through a wire. The controller is located inside the display screen 6, and the display screen 6 is fixedly installed at the front end of the bracket 8.
[0018] The workbench 1 is provided with a guide groove 11, and two guide blocks 10 are slidably connected on the guide groove 11. The two guide blocks 10 are fixed on the lower side of the left support seat 2 and the right support seat 3 respectively. By moving the guide blocks 10 along the guide groove 11, the left support seat 2 and the right support seat 3 can be moved, thereby adjusting the distance between the left support seat 2 and the right support seat 3.
[0019] Sliding grooves 4 are provided on the right side of the left support 2 and the left side of the right support 3. A protrusion 122 is slidably connected in the sliding groove 4. The protrusion 122 is integrally connected to the left and right ends of the tooling plate 12. The tooling plate 122 is slidably connected to the sliding groove 4 through the protrusion 122, which facilitates the assembly and disassembly of the tooling plate 12.
[0020] In use, this invention selects a fixture plate 12 that matches the touchscreen to be pressure tested, and then places the touchscreen into the positioning groove 121 on the fixture plate 12 to achieve stable placement of the touchscreen. Next, the guide block 10 is moved along the guide groove 11 to move the left support 2 and right support 3, thereby adjusting the distance between them. The fixture plate 12 is then slid between the left and right support 3, supporting both the fixture plate 12 and the touchscreen. This also facilitates disassembly of the fixture plate 12 and allows for support of fixture plates 12 and touchscreens of different specifications. Then, the hydraulic cylinder 7 is operated to move the pressure plate 5 and pressure sensor 9 downwards, allowing the pressure sensor 9 to contact the touchscreen surface. The hydraulic cylinder 7 operates at this point, and the pressure sensor 9 detects the pressure applied by the hydraulic cylinder 7 in real time. The detection data is then displayed on the screen 6 via the controller, achieving accurate pressure detection. The operation is simple and the detection accuracy is high.
