Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, specifically to a resistive touch screen pressure testing device. Background Technology

[0002] With the development of technology, resistive touchscreens have been widely used in various electronic devices. To ensure the quality and performance of resistive touchscreens, they need to be subjected to pressure testing to detect their response under different pressures.

[0003] Traditional touchscreen pressure testing devices first place the resistive touchscreen on a testing platform, and then a person presses different positions on the top of the touchscreen by hand, recording the deformation of the touchscreen during the press. However, existing touchscreen pressure testing devices rely on the primitive method of manual pressing, which not only consumes a lot of manpower and reduces testing efficiency, but also results in large dispersion of test results and a lack of uniform standards due to differences in the operator's hand strength, pressing speed, and method. This makes it impossible to truly reflect the pressure performance of the touchscreen, greatly limiting the reliability and application range of the device. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a resistive touchscreen pressure testing device. Through the coordinated structure of an adsorption turntable and testing components, it solves the problem that existing touchscreen pressure testing devices suffer from large discrepancies in test results and a lack of standardized parameters due to variations in operator hand strength, pressing speed, and method.

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

[0006] A resistive touchscreen pressure testing device includes a base with a sliding groove; a sliding block located within the sliding groove, a support seat fixed on the sliding block, a support block fixed at the bottom of the support seat, a positioning block fixed on the base, an electric telescopic rod mounted on the positioning block, the distal end of the electric telescopic rod being fixed to the support block, the electric telescopic rod driving the support seat to move linearly along the sliding groove to achieve automatic adjustment of the support seat position; and a testing component fixed on the base, which can accurately apply different pressures to the resistive touchscreen placed on the support seat.

[0007] Preferably, the test component includes a support frame fixed on the base, and the support frame has sliding holes.

[0008] Preferably, a vertical plate is fixed on the support frame, and a control motor is fixed on the vertical plate via a motor frame. This facilitates the construction of a stable motor mounting structure and makes it easier to control the motor to precisely drive the test components.

[0009] Preferably, a rocker arm is fixed on the output shaft of the control motor, and a rotating rod is rotatably connected to the rocker arm, which helps to convert the rotational motion of the motor into mechanical motion in a specific direction, and facilitates the adjustment of the position of the test contact.

[0010] Preferably, the distal end of the rotating rod is rotatably connected to a guide post, which is located inside the sliding hole. This helps to limit the movement trajectory of the guide post and facilitates precise control of the test contact moving along a preset path.

[0011] Preferably, a test contact is fixed at the bottom of the guide post, and a pressure sensor is installed on the guide post, which is conducive to obtaining the contact pressure data between the test contact and the touch screen in real time, facilitating precise control of the test pressure and recording feedback.

[0012] Preferably, a drive motor is fixed to the bottom of the support base via a motor frame, and a rotating disk is fixed to the output end of the drive motor. The rotating disk is located on the top of the support base, which is beneficial for driving the touch screen to perform multi-angle testing, thereby improving the comprehensiveness and accuracy of the test.

[0013] Preferably, a touch suction cup is fixed on the rotating disk, and a negative pressure pump is fixed at the bottom of the rotating disk. The touch suction cup is connected to the negative pressure pump, which helps to stably adsorb and fix the touch screen and prevents the screen from shifting during the test and affecting the test results.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its designed testing component, enables the control motor to start. When the output shaft of the control motor drives the rocker arm to rotate, the rotating rod moves with the rotation of the rocker arm, thereby driving the guide post to make linear reciprocating motion within the sliding hole. Unlike traditional pressure testing devices, this ensures that during the pressure testing process, whether different pressure levels are applied or the pressure is precisely adjusted, it can be monitored in real time by the pressure sensor. This truly achieves accurate testing of the pressure on resistive touchscreens and greatly improves the pressure testing effect.

[0016] 2. This utility model, through the design of a drive motor, rotating disk, touch suction cup, and negative pressure pump, allows the touch suction cup to flexibly adjust the testing angle of the touch screen when the drive motor starts, as the output end of the drive motor drives the rotating disk to rotate. At the same time, the negative pressure pump generates negative pressure, which in turn causes the touch suction cup to firmly adhere to the touch screen. Unlike the manual fixing method of traditional devices, this ensures that during pressure testing, whether it is a small precision touch screen or a large irregularly shaped touch screen, it can be stably clamped and accurately positioned, truly realizing automated multi-angle testing and greatly improving testing efficiency and stability.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example:

[0026] Please see Figure 1 - Figure 5 A resistive touchscreen pressure testing device includes a base 1 with a sliding groove 2; a sliding block 3 located within the sliding groove 2, a support seat 4 fixed on the sliding block 3, a support block 5 fixed at the bottom of the support seat 4, a positioning block 6 fixed on the base 1, an electric telescopic rod 7 mounted on the positioning block 6, the distal end of the electric telescopic rod 7 being fixed to the support block 5, the electric telescopic rod 7 driving the support seat 4 to move linearly along the sliding groove 2 to achieve automatic adjustment of the position of the support seat 4; and a testing component 8 fixed on the base 1, which can accurately apply different pressures to the resistive touchscreen placed on the support seat 4.

[0027] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0028] Please see Figure 1 - Figure 5 Through the designed test component 8, when the control motor 12 is started, the output shaft of the control motor 12 drives the rocker arm 13 to rotate, causing the rotating rod 14 to move with the rotation of the rocker arm 13, thereby driving the guide post 15 to make linear reciprocating motion in the sliding hole 10. Unlike traditional pressure testing devices, this ensures that during the pressure test, whether different pressures are applied or the pressure is precisely adjusted, it can be monitored in real time by the pressure sensor 17, truly realizing accurate testing of the pressure of the resistive touch screen and greatly improving the pressure testing effect.

[0029] Among them, the test component 8 includes a support frame 9 fixed on the base 1, and the support frame 9 has a sliding hole 10;

[0030] In addition, a vertical plate 11 is fixed on the support frame 9, and a control motor 12 is fixed on the vertical plate 11 via a motor frame. This helps to build a stable motor mounting structure and facilitates the control motor 12 to accurately drive the test component 8.

[0031] Meanwhile, a rocker arm 13 is fixed on the output shaft of the control motor 12, and a rotating rod 14 is rotatably connected to the rocker arm 13, which helps to convert the rotational motion of the motor into mechanical motion in a specific direction, and facilitates the adjustment of the position of the test contact 16.

[0032] In this technical solution, such as Figure 1 - Figure 5 As shown, a guide post 15 is rotatably connected to the far end of the rotating rod 14. The guide post 15 is located inside the sliding hole 10, which helps to limit the movement trajectory of the guide post 15 and facilitates precise control of the test contact 16 to move along the preset path. The test contact 16 is fixed at the bottom of the guide post 15, and a pressure sensor 17 is installed on the guide post 15, which helps to obtain the contact pressure data between the test contact 16 and the touch screen in real time, and facilitates precise control of the test pressure and recording of feedback.

[0033] The support base 4 has a drive motor 18 fixed at its bottom by a motor frame. The output end of the drive motor 18 is fixed with a rotating disk 19. The rotating disk 19 is located at the top of the support base 4, which is conducive to driving the touch screen to perform multi-angle testing, thereby improving the comprehensiveness and accuracy of the test.

[0034] In addition, a touch suction cup 20 is fixed on the rotating disk 19, and a negative pressure pump 21 is fixed at the bottom of the rotating disk 19. The touch suction cup 20 is connected to the negative pressure pump 21, which helps to stably adsorb and fix the touch screen and prevent the screen from shifting during the test and affecting the test results.

[0035] The working principle of test component 8 is explained below:

[0036] First, place the resistive touchscreen on the touch suction cup 20 on top of the support base 4, and start the negative pressure suction pump 21 to firmly fix the touchscreen using the principle of negative pressure adsorption. At the same time, the drive motor 18 can be started as needed. It is wirelessly connected to the pressure sensor 17 via Bluetooth. The operator issues commands on the remote terminal, and the drive motor 18 drives the rotating disk 19 and the touchscreen to rotate and adjust to the appropriate test angle.

[0037] Secondly, according to the test requirements, the electric telescopic rod 7 starts to work, and its output shaft extends and retracts to drive the support block 5, push the sliding block 3 to move linearly along the sliding groove 2 of the base 1, so that the bearing seat 4 drives the touch screen to accurately move to the designated position below the test component 8.

[0038] Then, the control motor 12 is powered on and operates, and it is wirelessly connected to the pressure sensor 17 via Bluetooth. The output shaft of the control motor 12 drives the rocker arm 13 to rotate, and the rocker arm 13 converts the rotational motion into the linear reciprocating motion of the guide post 15 within the sliding hole 10 via the rotating rod 14. The test contact 16 at the bottom of the guide post 15 applies pressure to the touch screen, and the pressure sensor 17 monitors the pressure value in real time and transmits the data to the control system in the form of a wireless signal. According to preset parameters, the control system sends commands to the control motor 12 via Bluetooth to precisely adjust the motor speed and the movement amplitude of the rocker arm 13, so as to achieve stable application and testing of different pressure values.

[0039] Finally, if testing is required on different areas of the touchscreen or under different pressure conditions, repeat the above position adjustment and pressure testing steps. During each test, the pressure sensor 17 continuously collects data and transmits it wirelessly to the terminal device via Bluetooth. The system automatically records and analyzes the performance of the touchscreen under various pressure conditions, completing the entire intelligent and wireless testing process. It should be noted that the electric telescopic rod 7, control motor 12, pressure sensor 17, drive motor 18, touch suction cup 20, and negative pressure pump 21 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, therefore, they will not be repeated in the specification.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principle, the implementation of the present invention may have any variations or modifications.
