Description

Technical Field

[0001] This utility model specifically relates to the field of aluminum foil removal technology, and more specifically to an electronic product press test device. Background Technology

[0002] With the widespread use of electronic products such as smartphones and tablets, the quality of their screens and the reliability of their buttons have become a key focus for consumers and manufacturers. As the most important interactive interface of electronic products, the screen is frequently subjected to pressing operations during use, such as clicking, swiping, and long-pressing. In order to ensure that the screen can work normally under prolonged pressing operations, pressing tests on electronic product screens have become crucial.

[0003] Traditional testing devices are relatively crude in terms of pressure control. If operated manually, the pressure applied by different operators varies significantly, making standardization difficult. Even some simple mechanical pressing devices usually lack a precise force adjustment mechanism, making it difficult to accurately output the set pressure. For example, when testing the precise trigger pressure required for electronic product screens or buttons, manual operation may misjudge the sensitivity of the screen or buttons due to excessive or insufficient force, while mechanical devices may fail to perform accurate testing due to pressure fluctuations.

[0004] Meanwhile, electronic product press testing devices have relatively limited functions and can usually only perform simple single-point press tests. They are difficult to effectively simulate complex touch operations common in modern electronic products, such as multi-touch (e.g., two-finger zoom, three-finger application switching), long press, and swipe operations. This makes it difficult for traditional devices to fully evaluate the performance of electronic products with advanced touch functions. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-6 In this embodiment of the utility model, an operating table 1 is included. A test bracket 2 is fixedly connected above the operating table 1. A lead screw drive module 21 is fixedly connected between the test brackets 2. A test arm 3 is slidably connected to the lead screw drive module 21. A linear drive module 6 is provided below the test arm 3. The linear drive module 6 is fixedly connected to the table surface of the operating table 1, and a test plate 7 is slidably connected to the linear drive module 6.

[0030] By adopting the above technical solution, the lead screw drive module 21 is stably connected to the test bracket 2, providing a precise horizontal movement track for the test arm 3. Due to the high precision and high stability of the lead screw drive module 21, the test arm 3 can slide smoothly on the lead screw drive module 21 and accurately position itself to the target test position above the electronic product. This ensures that whether testing the edge buttons of large-sized electronic products or detecting the touch points of small screens, the position can be accurate.

[0031] Furthermore, the test arm 3 and the test plate 7 are connected to the operating table 1 and the test bracket 2 respectively through different drive modules. This design allows each part to perform its own function. The test arm 3 is responsible for performing the pressing action, and the test plate 7 can assist in fixing or supporting the electronic product. The two work together under the drive of their respective drive modules. When the test arm 3 moves to the designated position under the drive of the lead screw drive module 21, the linear drive module 6 drives the test plate 7 to fine-tune the position so that the electronic product and the test head are accurately aligned. Then the test arm 3 can carry out the pressing test, which improves the smoothness and efficiency of the overall testing process.

[0032] In this embodiment, the test arm 3 includes an internal support 33. A motor mounting plate 37 is fixedly connected to one side of the top of the internal support 33. A servo motor 31 is fixedly connected to the motor mounting plate 37. A lead screw 34 is provided on one side of the servo motor 31. The lead screw 34 is rotatably connected to the motor mounting plate 37, and the upper end of the lead screw 34 extends outside the motor mounting plate 37.

[0033] By adopting the above technical solution, the lead screw 34 is rotatably connected to the motor fixing plate 37, and its upper end extends outside the plate. It works in conjunction with the servo motor 31 to form a high-precision linear transmission system. The servo motor 31 can accurately control the rotation angle and speed. With the help of the lead screw 34, the rotational motion of the motor is converted into linear motion, which drives the subsequent connecting parts to achieve precise vertical displacement. In the pressing test of electronic products, the pressing force can be controlled within a very small error range, accurately simulating the pressing force under various real use scenarios, and greatly improving the accuracy of the test results.

[0034] Furthermore, since the servo motor 31 drives the lead screw 34, the operator can easily change the output parameters of the servo motor through the control system, thereby flexibly adjusting the feed speed and stroke of the lead screw 34. In this way, the pressing force can be precisely adjusted as needed on the test head 36. Whether it is a capacitive touch button that responds with a light touch or a mechanical button that requires a larger pressing force, the appropriate force can be matched to carry out the test, thus expanding the range of electronic products that the device can test.

[0035] In this embodiment, a pulley is installed at one end of the output shaft of the servo motor 31, and a pulley is also installed at the upper end of the lead screw 34, and the pulleys are connected by belt drive.

[0036] By adopting the above technical solution, belt drive has a certain degree of elasticity. Compared with rigid connection, it can play a role in buffering and shock absorption during transmission. When the servo motor 31 starts, stops or its operating speed changes suddenly, it will generate instantaneous impact force. The belt can effectively absorb these impacts and prevent the impact force from being directly transmitted to the lead screw 34 and other precision components connected to it. This reduces the risk of wear and deformation of components due to rigid impact and extends the service life of the entire transmission system.

[0037] In this embodiment, the internal support 33 of the test arm has a rectangular groove in the middle, and a positioning block 32 is provided in the groove. The positioning block 32 is rotatably connected to the lead screw 34, and a test head fixing plate 35 is fixedly connected to one side of the positioning block 32. The test head fixing plate 35 is slidably connected to the internal support 33 of the test arm, and a test head 36 is fixedly connected to the bottom of the test head fixing plate 35.

[0038] By adopting the above technical solution, the rectangular groove in the middle of the internal support 33 of the test arm provides a precise motion track for the positioning block 32, limiting it to only move in a straight line along the groove. When the lead screw 34 rotates under the drive of the servo motor 31 and the transmission system, the positioning block 32, which is rotated in coordination with it, will produce a linear displacement in the vertical direction along the thread of the lead screw 34, making the entire motion process highly accurate, bringing a precise positioning effect to the test head 36 fixed below, and ensuring that the pressing operation can accurately act on the target test point of the electronic product.

[0039] Furthermore, the limiting plate on the outer side of the positioning block 32 and the limiters above and below the internal support 33 of the test arm can effectively ensure the accuracy and safety of the test action. During the test, when the lead screw 34 drives the positioning block 32 to move linearly along the rectangular groove of the internal support 33 of the test arm, the outer limiting plate will move synchronously with the positioning block 32. Once the positioning block 32 approaches the upper and lower boundaries of the stroke, the limiting plate will first contact the corresponding limiters above and below the internal support 33 of the test arm, preventing the test head 36 from applying a pressing force far exceeding the set value to the electronic product, thus avoiding damage to the test product. This not only protects the electronic product being tested but also ensures that the pressing force of each test is maintained within the preset precision range, guaranteeing the accuracy and reliability of the test data.

[0040] In this embodiment, a display screen 4 is provided on one side of the operating table 1, and a display screen bracket 12 is movably connected to the back of the display screen 4. The other side of the display screen bracket 12 is movably connected to the operating table 1.

[0041] By adopting the above technical solution, the back of the display screen 4 is movably connected to the display screen bracket 12, and the display screen bracket 12 is movably connected to the operating table 1. This dual movable connection design gives the display screen 4 a great degree of freedom in angle adjustment. Whether the operator is standing, sitting, or in different observation positions, they can easily move the display screen 4 and quickly adjust it to the most suitable observation angle, clearly capturing various key information in the testing process, such as the real-time pressing position of the test head and the touch feedback of the electronic product screen, making the testing work more accurate and efficient.

[0042] In this embodiment, the operating table 1 is provided with a control panel 11 and is electrically connected to the test arm 3. A push-pull plate 5 is provided below the control panel 11 and is slidably connected to the operating table 1.

[0043] By adopting the above technical solution, the control panel 11 is set on the tabletop of the operating console 1, which is within easy reach of the operator and can be easily operated. During the test, the operator can quickly adjust various test parameters in real time according to actual needs, such as precisely controlling the pressing pressure, flexibly changing the pressing frequency, or quickly switching test modes, making the test process compact and efficient, and greatly improving the overall ease of operation. At the same time, the push-pull plate 5 provides effective storage space, which can store computer keyboards or record forms, keeping the operating area clean and orderly.

[0044] In this embodiment, an inspection door 8 is provided below the push-pull plate 5 and is movably connected to the operating table 1. A heat dissipation door 13 is provided on the opposite side of the inspection door 8, and multiple heat dissipation holes are provided on the heat dissipation door 13.

[0045] By adopting the above technical solution, when the equipment malfunctions during the pressing test of electronic products, technicians only need to open the inspection door 8 to quickly access the core components inside the device, such as the computer host, transmission module, and wiring connection points, and conduct intuitive inspection, repair or replacement of potentially problematic parts, which greatly shortens the time for troubleshooting and repair and reduces production delays caused by equipment downtime.

[0046] Furthermore, a heat dissipation door 13 is opened on the opposite side of the inspection door 8, and the heat dissipation door 13 is covered with multiple heat dissipation holes, providing a heat dissipation system for the equipment. During the operation of the equipment, especially key components such as motors and controllers that are in working condition for a long time, a lot of heat will be generated. The heat dissipation holes can promote the air circulation inside and outside the equipment, expel the internal hot air, introduce the outside cold air, maintain the internal temperature range of the equipment, effectively avoid the performance degradation, shortened lifespan, or even sudden failure of components caused by overheating, and ensure the stable and long-term operation of the equipment.

[0047] In this embodiment, the bottom of the operating table 1 is fixedly connected with a plurality of casters 10, and a plurality of support legs 9 are provided on one side of the casters 10, and the support legs 9 are rotatably connected to the operating table 1.

[0048] By adopting the above technical solution, multiple casters 10 are fixedly connected to the bottom of the operating table 1, which gives the equipment easy mobility. Whether adjusting the test station in the production workshop or needing to move the device to other sites for temporary testing, the operator only needs to push it gently, and the device can flexibly turn and smoothly move with the help of the casters 10.

[0049] Furthermore, a support leg 9 is provided on one side of the caster wheel 10 and is rotatably connected to the control panel 1, providing reliable stability for the equipment during operation. When the device moves to the designated position to start performing the test task, the support leg 9 is rotated and lowered so that it makes stable contact with the ground.

[0050] In this embodiment, a movable plate 22 is provided on one side of the lead screw drive module 21 and is slidably connected to the lead screw drive module 21, and the other side of the movable plate 22 is fixedly connected to the internal support 33 of the test arm.

[0051] By adopting the above technical solution, the moving plate 22 is slidably connected to the lead screw drive module 21. When the lead screw drive module 21 is activated, it can drive the moving plate 22 to make a smooth and precise linear movement along the predetermined track. By using the moving plate 22 as an intermediate connecting part, this precise displacement is transmitted to the internal support 33 of the test arm, thereby ensuring that the test arm 3 is accurately positioned when moving in the horizontal direction, and effectively improving the accuracy of the test position.

[0052] The working principle of this utility model is as follows: First, the electronic product to be tested is placed on the test board 7. Then, according to the testing requirements of this electronic product, various test parameters are input through the control panel 11, which is within easy reach on the operation table 1. These parameters include key information such as the horizontal and vertical movement position of the test arm 3, the pressing force and pressing frequency of the test head 36.

[0053] After the test is started, the servo motor 31 starts to run according to the parameters set on the control panel 11. Its output shaft rotates in conjunction with the installed pulley, and the power is transmitted to the lead screw 34 through belt drive. The lead screw 34 rotates on the motor fixing plate 37. At this time, the positioning block 32, which is located in the rectangular groove of the internal support 33 of the test arm and cooperates with the lead screw 34, will make a vertical linear movement along the thread of the lead screw 34, which will drive the test head fixing plate 35 connected to it and the test head 36 at the bottom to move vertically in sync. During this process, the output parameters of the servo motor 31 can be precisely controlled by the control system. At the same time, the limiting plate on the outside of the positioning block 32 and the limiter of the internal support 33 of the test arm work together to prevent the test head 36 from exceeding the set stroke and avoid excessive pressing to prevent damage to electronic products.

[0054] At the same time, the lead screw drive module 21 receives the instruction and starts to work. The lead screw rotates in the module, driving the sliding plate 22, which is slidably connected to it, to slide smoothly and accurately along the predetermined track in the horizontal direction. Since the sliding plate 22 is fixedly connected to the internal support 33 of the test arm, the test arm 3 also moves accurately in the horizontal direction, allowing the test head 36 to be positioned at the target test position in the horizontal direction above the electronic product, which greatly improves the detection accuracy of the screen or buttons of the electronic product.
