Description

Technical Field

[0001] This utility model relates to the field of touch screen testing technology, specifically a robotic arm for a touch screen button life testing machine. Background Technology

[0002] Touchscreen button life testing machines are primarily used to simulate high-frequency user touch operations, evaluating the mechanical durability and performance stability of various touch devices such as mobile phones, tablets, vehicle central control systems, and industrial control panels. Utilizing a multi-axis robotic arm equipped with bionic contacts, it can accurately reproduce interactive actions such as clicking, swiping, pressing, and multi-finger zooming. It supports setting parameters such as pressure, speed, and trajectory, adapting to the differentiated testing needs of capacitive, resistive, and novel flexible screens. Combined with an environmental chamber, it can simulate extreme conditions such as high and low temperatures, humidity, and salt spray, simultaneously collecting data on touch sensitivity and response latency. This provides quantitative evidence for product reliability verification, quality improvement, and lifespan prediction, and is widely used in R&D and quality control processes in consumer electronics, automotive electronics, and medical devices.

[0003] However, the existing robotic arms have poor overall automation control, most of which require manual adjustment, and their stroke range is relatively short. Therefore, after a single set of touch screen click tests is completed, it is necessary to wait for manual removal and installation of the touch screen before the next set of screens can be installed before the test can continue. The waiting time is long, resulting in a decrease in efficiency. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A robotic arm for a touchscreen button life testing machine includes connecting plates 101, a driving mechanism 102 disposed between the connecting plates 101, a sliding rod 103 movably mounted on the connecting plates 101, the sliding rod 103 being fixedly mounted on the top of a lower pressure plate 104, a click rod 105 being screwed onto the bottom of the lower pressure plate 104, the driving mechanism 102 including a hydraulic cylinder 106, a hydraulic rod 201 movably mounted on the bottom of the hydraulic cylinder 106, connecting plates 101 being fixedly mounted on both sides of the hydraulic cylinder 106 away from the hydraulic rod 201, and the lower pressure plate 104 being fixedly mounted on the bottom of the hydraulic rod 201.

[0023] The above solution uses a connecting plate to support the click component. The sliding rod on the connecting plate ensures stability when the lower pressure plate moves the click rod up and down during the click. The hydraulic cylinder drives the hydraulic rod to extend and retract, which in turn moves the lower pressure plate and the click rod up and down during the click.

[0024] In this embodiment, preferably, the driving mechanism 102 further includes a base 203, a first motor 204 is rotatably mounted on the top of the base 203, a second motor 205 is rotatably mounted on the side of the first motor 204 away from the base 203, and a third motor 206 is rotatably mounted on the side of the second motor 205 away from the first motor 204.

[0025] The above solution allows the base to support and fix the robotic arm structure, while the first motor drives the second motor to rotate, and the second motor in turn drives the robotic arm to rotate on the first motor.

[0026] In this embodiment, preferably, a fourth motor 301 is rotatably mounted on the side of the third motor 206 away from the second motor 205, a fifth motor 302 is rotatably mounted on the side of the fourth motor 301 away from the third motor 206, and a hydraulic telescopic arm 303 is fixedly mounted on the side of the fifth motor 302 away from the fourth motor 301.

[0027] With the above scheme, the third motor can drive itself to rotate on the second motor, the fourth motor can drive itself to rotate on the third motor, the fifth motor can drive itself to rotate on the fourth motor, and the extension and retraction of the hydraulic telescopic arm can cause the sixth motor to move.

[0028] In this embodiment, preferably, a sixth motor 304 is fixedly installed on the side of the hydraulic telescopic arm 303 away from the fifth motor 302, a support arm 305 is fixedly installed on the side of the sixth motor 304 away from the hydraulic telescopic arm 303, and a hydraulic cylinder 106 is fixedly installed on the side of the support arm 305 away from the fifth motor 302.

[0029] The above scheme allows the sixth motor to drive the support arm to rotate, thereby causing the hydraulic cylinder to rotate, and the support arm can then support the hydraulic cylinder.

[0030] In this embodiment, preferably, an assembly plate 306 is fixedly installed at the bottom of the base 203. The assembly plate 306 is fixedly installed at the top of the screw block 401 and the sliding block 402. The sliding block 402 is movably installed on the slide rail 403. The slide rail 403 is fixedly installed at the top of the sliding frame 404. A fixing plate 405 is fixedly installed at the bottom of the sliding frame 404. The fixing plate 405 has fixing holes 406.

[0031] The above scheme allows the screw block and sliding block to be connected simultaneously via the assembly plate. The sliding block's movement on the slide rail makes the overall robotic arm structure more stable. The fixing holes allow the fixing plate to be fixed, thus completing the assembly of the sliding frame. Components can then be installed through the sliding frame.

[0032] In this embodiment, preferably, the screw block 401 is screwed and installed on the outside of the threaded rod 501, the threaded rod 501 is movably installed inside the sliding frame 404, the threaded rod 501 passes through the sliding frame 404 and is fixedly installed on the driving end of the drive motor 502, and the drive motor 502 is fixed on the side of the sliding frame 404 away from the slide rail 403.

[0033] The above scheme uses a drive motor to rotate the threaded rod, which causes the moving block to move on the threaded rod, thus enabling the entire robotic arm structure to complete the displacement.

[0034] In this embodiment, a robotic arm for a touchscreen button life testing machine is used by the user to fix the fixing plate 405 to the testing machine through the fixing hole 406, thus fixing the overall structure. After fixing, the user screws the click rods 105 onto the lower pressure plate 104 according to the number of screens to be tested. Then, the robotic arm control device controls the overall operation, such as the control device disclosed in Publication No. (201910542115.6 A robotic arm control method, robotic arm control device and terminal device). It can be controlled through program setting, stroke setting, etc. Therefore, after the whole is powered on, it can control the first motor 204 to drive the second motor 205 to rotate, the second motor 205 to drive itself to rotate on the first motor 204, the third motor 206 to drive itself to rotate on the second motor 205, the fourth motor 301 to drive itself to rotate on the third motor 206, the fifth motor 302 to drive itself to rotate on the fourth motor 301, the hydraulic telescopic arm 303 to extend and retract, the sixth motor 304 to drive the support arm 305 and the hydraulic cylinder 106 to rotate, and the hydraulic cylinder 106 to drive the support arm 305 and the hydraulic cylinder 106 to rotate. The hydraulic rod 201 extends and retracts hydraulically, and the stroke control can also drive the drive motor 502 to work, causing the threaded rod 501 to rotate and drive the screw block 401 to move. The movement causes the fixed plate 405, along with the sliding block 402, to slide on the slide rail 403. Therefore, the overall structure can generate stable displacement, and thus the overall structure can automatically adjust according to the position of the touch screen and start the click test. During the test, the hydraulic cylinder 106 drives the hydraulic rod 201 to repeatedly extend and retract, causing the lower pressure plate 104 to extend and retract. During the extension and retraction, the sliding rod 103 is connected to the slide rail 403. The sliding within the connecting plate 101 makes the up-and-down clicking of the click rod 105 more stable. The sliding frame 404 inside the robotic arm structure can be configured with a pleated sleeve according to the usage environment, so that the threaded rod 501 will not be exposed when the robotic arm structure is displaced, avoiding the entry of foreign objects into the threaded rod 501 and causing displacement errors. In addition, the added hydraulic telescopic arm 303 can increase the stroke of the click rod 105. The principle of the hydraulic telescopic arm 303 is the same as the principle of the hydraulic cylinder 106 driving the hydraulic rod 201 to extend and retract. Together with the drive motor 502 to drive the displacement, the screen click test can be more comprehensive.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
