Description

Technical Field

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

[0002] A touchscreen touch tester is a device specifically designed to test and verify the performance of touchscreens. It can simulate user touch operations to ensure the accuracy and stability of the touchscreen's response under various conditions.

[0003] Simulating human hand touch actions usually involves touch testing using simulated fingers. However, since human hands vary in size, the size and specifications of simulated fingers also vary. Touchscreen touch testers need to be replaced with simulated fingers of different sizes for testing. Currently, the simulated fingers on existing touchscreen touch testers need to be replaced manually, as they cannot be replaced automatically, which greatly reduces the testing efficiency of touchscreens. Utility Model Content

[0004] The purpose of this invention is to provide a touch screen touch tester to solve the problem mentioned in the background art that the simulated fingers on existing touch screen touch testers need to be replaced manually and cannot be replaced automatically, which greatly reduces the testing efficiency of touch screens.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a touchscreen touch tester, comprising a base, a support frame slidably connected to the surface of the base, a movable stage slidably connected to the surface of the base, a touch mechanism provided on the surface of the support frame, the touch mechanism comprising a first cylinder, the first cylinder being fixedly connected to the surface of the support frame, a connecting frame being fixedly connected to the piston rod of the first cylinder, a connecting plate being fixedly connected to the surface of the connecting frame, a first motor being fixedly connected to the surface of the connecting plate, a turntable being fixedly connected to the output shaft of the first motor, a second cylinder being fixedly connected to the surface of the connecting plate, a pressing block being fixedly connected to the piston rod of the second cylinder, a support spring being fixedly connected to the surface of the turntable, a support ring being fixedly connected to the surface of the support spring, and a simulated finger being fixedly connected to the surface of the support ring, the simulated finger being slidably connected to the surface of the turntable.

[0006] Preferably, an adjustment mechanism is provided on the surface of the movable stage. The adjustment mechanism includes a support rod, which is fixedly connected to the surface of the movable stage. A contact platform is rotatably connected to the surface of the support rod. A second motor is fixedly connected to the surface of the movable stage. A lead screw is fixedly connected to the output shaft of the second motor. A square nut is threaded onto the surface of the lead screw. An adjustment rod is rotatably connected to the surface of the square nut. The end of the adjustment rod away from the square nut is rotatably connected to the lower surface of the contact platform.

[0007] Preferably, the first cylinder drives the connecting frame to rise and fall via the piston rod, the connecting frame drives the turntable to rise and fall via the connecting disc, and the turntable drives the simulated finger to rise and fall via the support spring and support ring.

[0008] Preferably, multiple sets of simulated fingers are arranged on the turntable, and the multiple sets of simulated fingers are evenly arranged in a circle on the turntable. The first motor drives the turntable to rotate through the output shaft, and the rotation of the turntable changes the relative positions between the simulated fingers.

[0009] Preferably, the elastic force of the support spring acts on the simulated finger through the support ring, and a guide hole is provided on the surface of the turntable. The simulated finger slides and rises and falls on the guide hole of the turntable. The second cylinder drives the extrusion block to rise and fall on the connecting plate through the piston rod. During the descent of the extrusion block, it pushes the simulated finger to slide downward on the turntable.

[0010] Preferably, the touch panel rotates on the moving platform via a support rod, and a clamping device is provided on the touch panel. The touch panel limits the touch screen through the clamping device, and the touch panel drives the touch screen to rotate synchronously.

[0011] Preferably, the second motor drives the lead screw to rotate on the moving platform via its output shaft. The lead screw drives the square nut to slide on the surface of the moving platform via its rotation. During the sliding process, the square nut drives the contact plate to rotate on the moving platform via an adjusting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This tester uses the output shaft of a first motor to drive a turntable to rotate. The rotation of the turntable changes the position of multiple sets of simulated fingers, rotating the simulated finger to be tested directly below the squeezing block. Simultaneously, a second cylinder changes the piston rod to drive the squeezing block to descend. The squeezing block pushes the simulated finger to slide downward on the guide hole of the turntable, making the simulated finger for touch testing lower than the height of the other simulated fingers. At this time, the simulated finger at a lower height will perform touch testing during the lifting and lowering process, realizing automatic replacement of simulated fingers for touch testing of the touch screen without the need for manual replacement of simulated fingers, thus improving the testing efficiency of the touch screen.

[0014] 2. This tester uses the output shaft of the second motor to drive the lead screw to rotate. The lead screw drives the square nut to slide on the surface of the moving stage. During the sliding process, the square nut drives the touch panel to rotate on the support rod through the adjusting rod, thereby changing the tilt angle of the touch panel on the moving stage, and thus changing the tilt angle of the touch screen on the touch panel. By performing touch tests on the touch screen at different angles, the touch habits of different users can be simulated, and the performance of the touch screen under different usage conditions can be evaluated more accurately.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A touchscreen touch tester includes a base 1, a support frame 11 slidably connected to the surface of the base 1, and a moving stage 12 slidably connected to the surface of the base 1. Both the support frame 11 and the moving stage 12 are equipped with driving mechanisms to move them, allowing the touchscreen to continuously change its touch test position during touch testing. A touch mechanism is provided on the surface of the support frame 11, including a first cylinder 2 fixedly connected to the surface of the support frame 11. A connecting frame 21 is fixedly connected to the piston rod of the first cylinder 2, a connecting plate 22 is fixedly connected to the surface of the connecting frame 21, and a first motor 23 is fixedly connected to the surface of the connecting plate 22. A turntable 24 is fixedly connected to the output shaft of the first motor 23. A second cylinder 25 is fixedly connected to the surface of the connecting plate 22. A pressing block 26 is fixedly connected to the piston rod of the second cylinder 25. A support spring 27 is fixedly connected to the surface of the turntable 24. A support ring 28 is fixedly connected to the surface of the support spring 27. A simulated finger 29 is fixedly connected to the surface of the support ring 28. The simulated finger 29 is slidably connected to the surface of the turntable 24. This touch mechanism can automatically replace the simulated finger 29 to perform touch testing on the touch screen after a set of simulated fingers 29 has completed the touch test, without the need for manual replacement of the simulated fingers 29, thus improving the testing efficiency of the touch screen.

[0024] Furthermore, an adjustment mechanism is provided on the surface of the moving platform 12. The adjustment mechanism includes a support rod 3, which is fixedly connected to the surface of the moving platform 12. A touch panel 31 is rotatably connected to the surface of the support rod 3. A second motor 32 is fixedly connected to the surface of the moving platform 12. A lead screw 33 is fixedly connected to the output shaft of the second motor 32. A square nut 34 is threaded onto the surface of the lead screw 33. An adjustment rod 35 is rotatably connected to the surface of the square nut 34. The end of the adjustment rod 35 away from the square nut 34 is rotatably connected to the lower surface of the touch panel 31. The adjustment mechanism can adjust the angle of the touch panel 31, thereby adjusting the angle when the touch screen is touched. By conducting touch tests at different angles of the touch screen, the touch habits of different users can be simulated, and the performance of the touch screen under different usage conditions can be evaluated more accurately.

[0025] Furthermore, the first cylinder 2 drives the connecting frame 21 to rise and fall through the piston rod, the connecting frame 21 drives the turntable 24 to rise and fall through the connecting plate 22, and the turntable 24 drives the simulated finger 29 to rise and fall through the support spring 27 and the support ring 28. The simulated finger 29 performs touch testing on the touch screen during the rising and falling process.

[0026] Furthermore, multiple sets of simulated fingers 29 are set on the turntable 24, and the multiple sets of simulated fingers 29 are arranged in a circular and uniform manner on the turntable 24. The first motor 23 drives the turntable 24 to rotate through the output shaft. The rotation of the turntable 24 changes the relative position between the simulated fingers 29. The change in the relative position of the simulated fingers 29 allows the simulated fingers 29 to be replaced with another set of simulated fingers 29 after the touch is completed for touch testing.

[0027] Furthermore, the elastic force of the support spring 27 acts on the simulated finger 29 through the support ring 28. A guide hole is provided on the surface of the turntable 24. The simulated finger 29 slides and rises and falls on the guide hole of the turntable 24. The second cylinder 25 drives the extrusion block 26 to rise and fall on the connecting plate 22 through the piston rod. During the descent of the extrusion block 26, it pushes the simulated finger 29 to slide downward on the turntable 24, so that the height of one group of simulated fingers 29 is lower than that of all other simulated fingers 29. At this time, during the descent and touch process of multiple groups of simulated fingers 29, only this group of simulated fingers 29 performs the touch test. After the touch is completed, the simulated finger 29 will return to its original height under the elastic force of the support spring 27.

[0028] Furthermore, the touch platform 31 rotates on the moving platform 12 via the support rod 3. A clamping device is provided on the touch platform 31. The touch platform 31 limits the touch screen through the clamping device. The touch platform 31 drives the touch screen to rotate synchronously, thereby changing the tilt angle of the touch screen and thus changing the touch angle of the touch screen, providing a more complex environment for simulating the touch test of the finger 29.

[0029] Furthermore, the second motor 32 drives the lead screw 33 to rotate on the moving platform 12 via the output shaft. The lead screw 33 drives the square nut 34 to slide on the surface of the moving platform 12 via rotation. During the sliding process, the square nut 34 drives the contact platform 31 to rotate on the moving platform 12 via the adjusting rod 35. When the square nut 34 is not sliding on the moving platform 12, the lead screw 33 restricts the position of the square nut 34 on the moving platform 12. The square nut 34 supports the contact platform 31 via the adjusting rod 35, thereby ensuring the angle of the contact platform 31 on the moving platform 12.

[0030] Working principle: The output shaft of the first motor 23 drives the turntable 24 to rotate. The rotation of the turntable 24 changes the position between multiple sets of simulated fingers 29, rotating the simulated finger 29 to be tested directly below the squeezing block 26. The second cylinder 25 simultaneously changes the piston rod to drive the squeezing block 26 to descend. The squeezing block 26 pushes the simulated finger 29 to slide downward on the guide hole of the turntable 24, so that the simulated finger 29 to be tested is lower than the height of the other simulated fingers 29. At this time, the simulated finger 29 with the lower height will perform touch test during the lifting and lowering process, realizing automatic replacement of simulated fingers 29 to perform touch test on the touch screen without manual replacement of simulated fingers 29, thus improving the testing efficiency of the touch screen.

[0031] The output shaft of the second motor 32 drives the lead screw 33 to rotate. The lead screw 33 drives the square nut 34 to slide on the surface of the moving platform 12. During the sliding process, the square nut 34 drives the touch panel 31 to rotate on the support rod 3 through the adjusting rod 35, thereby changing the tilt angle of the touch panel 31 on the moving platform 12, and thus changing the tilt angle of the touch screen on the touch panel 31. By conducting touch tests on the touch screen at different angles, the touch habits of different users can be simulated, and the performance of the touch screen under different usage conditions can be evaluated more accurately.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
