[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Example 1: Please refer to Figures 1-6The resistive touchscreen surface pressing device shown in the figure includes a base plate 1, side plates 2 symmetrically mounted on the base plate 1, mounting plates 3 mounted on the two side plates 2, and further includes: a moving part 4 mounted on the top of the two side plates 2, a pressing assembly 6 detachably mounted on the moving part 4, the pressing assembly 6 being used to press the touchscreen; and a positioning part 5 mounted on the mounting plate 3, the positioning part 5 being used to position the touchscreen.

[0029] Furthermore, the moving component 4 includes a mounting frame 8 installed on the two side plates 2, made of high-strength aluminum alloy, which is characterized by high hardness and light weight, thus reducing the overall weight of the equipment. A motor 7 is mounted externally on the mounting frame 8; a servo motor is selected, which has high-precision position control, fast response speed, and good speed regulation performance, enabling precise control of the moving position and speed of the pressing assembly 6. The output end of the motor 7 is fixedly connected to a lead screw 9 through the mounting frame 8 via a coupling. The lead screw 9 is a high-precision ball screw, characterized by high hardness, low friction coefficient, and high transmission efficiency. The end of the lead screw 9 furthest from the motor 7 is rotatably connected to the inner wall of the mounting frame 8.

[0030] Furthermore, the lead screw 9 is externally threaded with a slider 10. The slider 10 is slidably connected to the inner wall of the mounting frame 8 via a linear guide rail, ensuring the slider 10 remains stable during movement and also limiting its horizontal movement. A through slot 11 is provided at the bottom of the mounting frame 8, through which the bottom of the slider 10 extends to connect with the pressing assembly 6. The moving component 4 ensures the pressing assembly 6's positional accuracy reaches the millimeter or even micrometer level, guaranteeing the accuracy of the pressing process. After the motor 7 starts, power is transmitted to the lead screw 9 via a coupling, causing the lead screw 9 to rotate. Because the slider 10 is threadedly connected to the lead screw 9, the rotational motion of the lead screw 9 is converted into the linear motion of the slider 10. Guided by the linear guide rail, the slider 10 moves smoothly along the inner wall of the mounting frame 8, thereby moving the pressing assembly 6 to the designated position.

[0031] Specifically: Please refer to Figure 5 and Figure 6The pressing assembly 6 includes a hydraulic cylinder 12 installed at the bottom of the slider 10. The hydraulic cylinder 12 is a high-precision, high-thrust model. The output end of the hydraulic cylinder 12 is fixedly connected to a connecting plate 13. The connecting plate 13 is made of high-strength stainless steel, which is corrosion-resistant and has high strength. Electromagnetic attractors 14 are symmetrically installed at the bottom of the connecting plate 13, and magnetic attracting protrusions 15 are symmetrically installed on the connecting plate 13. The magnetic attracting protrusions 15 are engaged with a pressure plate 16. The pressure plate 16 has a locking hole 17 for the magnetic attracting protrusions 15 to be engaged. When the magnetic attracting protrusions 15 are engaged at the bottom of the locking hole 17, the pressure plate 16 is in an energized state. An elastic spring is installed inside the locking hole 17. The sleeve 18 is made of highly elastic rubber, which has good wear resistance and elasticity. The elastic sleeve 18 can provide elastic pressure for the magnetic protrusion 15, ensuring that it remains locked after multiple disassemblies. The pressure plate 16 is equipped with a fixing block 19 corresponding to the electromagnetic suction 14. The fixing block 19 is made of ferromagnetic material. When the electromagnetic suction 14 is energized, it attracts the fixing block 19, which helps to maintain the stability of the connection between the pressure plate 16 and the connecting plate 13. The combination design of the electromagnetic suction 14 and the magnetic protrusion 15 makes the installation and disassembly of the pressure plate 16 convenient and quick. At the same time, the elastic sleeve 18 ensures that it remains locked after multiple disassemblies, improving work efficiency and connection stability.

[0032] Example 2: This embodiment is a further explanation of Example 1, based on... Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the pressure plate 16 is evenly provided with exhaust holes 20. The diameter of the exhaust holes 20 is distributed in a trapezoidal shape from small to large. The gas flows in from bottom to top, which facilitates the entry and exit of air bubbles into the exhaust holes 20 and their discharge, further reducing the impact of air bubbles on the touch screen components. A filter screen 21 is installed inside the exhaust holes 20 to prevent foreign objects from entering the exhaust holes 20.

[0033] Please see Figure 6 Specifically, a heating wire 22 is installed inside the pressure plate 16. The heating wire 22 is made of high-purity nickel-chromium alloy wire. The heating wire 22 can heat the pressure plate 16 to a suitable temperature as needed, further improving the efficiency of the touch screen pressing. An ultrasonic generator 23 is installed on one side of the heating wire 22. An ultrasonic transducer 24 is installed outside the ultrasonic generator 23. The ultrasonic generator 23 and the ultrasonic transducer 24 work together to break up large air bubbles, thereby decomposing the air bubbles and improving the pressing effect of the touch screen.

[0034] Further reference Figure 1 and Figure 3As shown, the positioning component 5 includes an air pump 25 installed at the bottom of the mounting plate 3. The air pump 25 is a quiet, high-negative-pressure model, and its shell is made of high-strength plastic, which is lightweight and corrosion-resistant. The quiet, high-negative-pressure air pump 25 can provide stable suction while reducing noise pollution during operation. An exhaust valve 26 is installed at the output end of the air pump 25, and an air inlet pipe 27 is fixedly connected to the input end of the air pump 25. The air inlet pipe 27 passes through the mounting plate 3 and is fixedly connected to the positioning plate 28. The positioning plate 28 is made of high-strength plastic, and suction holes 29 are evenly opened inside the positioning plate 28. Each suction hole 29 is equipped with a control valve (not shown in the figure), which can accurately position the touch screen according to its size and further prevent displacement from affecting the pressing effect of the touch screen. When the touch screen needs to be positioned, the air pump 25 is started and draws air from the suction holes 29 of the positioning plate 28 through the air inlet pipe 27, so that a negative pressure is formed on the surface of the positioning plate 28. Depending on the size of the touchscreen, the working state of the air intake 29 is adjusted by controlling the opening and closing of a high-precision solenoid valve, thereby firmly attaching the touchscreen to the positioning plate 28 for precise positioning. After pressing is complete, the air pump 25 stops working, the exhaust valve 26 opens, releasing the negative pressure on the surface of the positioning plate 28, making it easier to remove the touchscreen.

[0035] The principle behind this solution is as follows:

[0036] First, after the motor 7 starts, it transmits power to the lead screw 9 through the coupling, causing the lead screw 9 to start rotating. The lead screw 9 drives the slider 10 to slide, thereby moving the pressing assembly 6 to the designated position.

[0037] Secondly, after the slider 10 moves the pressing assembly 6 to the designated position, the hydraulic cylinder 12 is activated, and its output end pushes the connecting plate 13 downward, so that the pressing plate 16 contacts the touch screen surface. During the pressing process, the heating wire 22 is energized and heats up, heating the pressing plate 16 to a suitable temperature to improve the adhesion effect of the touch screen. The ultrasonic generator 23 generates a high-frequency electrical signal, which is converted into ultrasonic vibration by the ultrasonic transducer 24. This vibration breaks up large air bubbles between the touch screen and the pressing material, decomposing them into tiny air bubbles that can be easily discharged through the vent 20.

[0038] Finally, when the touchscreen needs to be positioned, the air pump 25 starts, drawing air through the air inlet pipe 27 from the suction port 29 of the positioning plate 28, creating a negative pressure on the surface of the positioning plate 28. Depending on the size of the touchscreen, the working state of the suction port 29 is adjusted by controlling the opening and closing of the high-precision solenoid valve, thereby firmly adhering the touchscreen to the positioning plate 28 and achieving precise positioning. Once the pressing is complete, the air pump 25 stops working, and the exhaust valve 26 opens, releasing the negative pressure on the surface of the positioning plate 28, making it easy to remove the touchscreen.

[0039] It should be noted that the motor 7, hydraulic cylinder 12, electromagnetic suction 14, heating wire 22, ultrasonic generator 23 and air pump 25 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
