[0054] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0055] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0056] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a pressing test device, which includes a test platform 1, a pressing mechanism 2, a clamping mechanism 3, a swing opening and closing mechanism 4, a lifting support mechanism 5, and a gravity load mechanism 6. The test platform 1 has a support surface for supporting the device under test. The pressing mechanism 2 is disposed above the test platform 1 and is used to apply a test pressure towards the test platform 1. The clamping mechanism 3 is disposed in the test platform 1 and is used to clamp and fix the device under test. The swing opening and closing mechanism 4 is disposed in the test platform 1 and is used to swing open and close the device under test. The lifting support mechanism 5 is disposed below the test platform 1 and is used to support and lift the device under test from the test platform 1. The gravity load mechanism 6 is disposed in the test platform 1 and can adjust its own position to apply a gravity load to the device under test.

[0057] The pressing test device provided in this embodiment can be applied, but is not limited to, to pressing tests of the logical upper cover and logical lower cover of a laptop casing under pressure and warping at the front corner. The usage process will be described using this as an example.

[0058] In use, the pressure testing device first places the laptop under test onto the support platform of the test stage 1 using the clamping mechanism 3, and then lifts the laptop to a preset height using the lifting support mechanism 5, thus fixing the laptop in three-dimensional space. Next, the laptop is opened to a preset angle (e.g., 120°) using the swing opening and closing mechanism 4, and a fixed amount of test pressure is applied to the laptop using the pressing mechanism 2 to test the pressure resistance of the top cover of the laptop casing. After the pressing mechanism 2 completes its press and returns to its original position, the lifting support mechanism 5 lowers the laptop back onto the test stage 1, placing it flat on the support platform. The swing opening and closing mechanism 4 continues to maintain the previous opening and closing angle. Then, the gravity load mechanism 6 places a preset amount of gravity load into the laptop to test the pressure resistance of the bottom cover of the laptop casing, and measures and records the change in distance between the laptop and the lifting support mechanism 5. This completes one stage of the press test on the front corner of the laptop casing to be tested, which measures the warping condition of the top and bottom logical covers. This stage of the press test can be repeated two or three times to complete the final test on the warping condition of the top and bottom logical covers of the laptop casing to be tested.

[0059] Compared with the existing technology that uses manual testing of the warping of laptop casing parts under stress, the pressing test device provided in this disclosure can achieve fully automatic or semi-automatic testing. Moreover, the test parameters can be precisely controlled throughout the testing process, effectively avoiding the problem of test errors and having the beneficial effect of fully meeting the requirements of test accuracy.

[0060] In one embodiment, the pressing mechanism 2 includes a pressing head 21, a slide rail 22, and a fixed rail 23. The pressing head 21 includes a pressure sensor and a first drive, and the first drive is used to reciprocate the pressing head 21 in the up-down direction. The slide rail 22 extends horizontally and is connected to the pressing head 21 via a linear motor to drive the pressing head 21 to reciprocate along the slide rail 22. The fixed rail 23 is perpendicular to the slide rail 22 in the horizontal direction and is connected to the slide rail 22 via a drive motor to drive the slide rail 22 to reciprocate along the fixed rail 23.

[0061] Specifically, in combination Figure 2To further explain, the pressing mechanism 2 is specifically configured to include a pressing head 21, a slide rail 22, and a fixed rail 23. The first drive in the pressing head 21 can be, but is not limited to, a cylinder, hydraulic cylinder, motor, electric spring, etc., to enable the pressing head 21 to output a fixed magnitude of pressing test force. The pressure sensor installed in the pressing head 21 can also accurately detect and record the real-time pressing test force output by the pressing head 21 to ensure that it meets the test requirements. In addition, the slide rail 22 is equipped with a linear motor that is connected to the pressing head 21 for transmission, and the fixed rail 23 is connected to the drive motor that is connected to the slide rail 22 for transmission, and can drive the slide rail 22 to move back and forth along the fixed rail 23. In this way, by adjusting the relative position of the slide rail 22 in the fixed rail 23, the relative position of the pressing head 21 in the slide rail 22, and the vertical position of the pressing head 21 itself, the point of application of the pressing test force of the pressing mechanism 2 can be accurately adjusted in three-dimensional space, further improving the testing flexibility and universal adaptability of the pressing mechanism 2.

[0062] In one embodiment, the pressing mechanism 2 further includes a rangefinder 24 disposed in the pressing head 21; the rangefinder 24 is disposed toward the test platform 1 and is used to measure the distance between the pressing head 21 and the platform surface.

[0063] Specifically, in combination Figure 1 and Figure 2 To further explain, the aforementioned rangefinder 24 can be specifically, but not limited to, an infrared sensor rangefinder, an ultrasonic rangefinder, etc., and the real-time measurement information of the rangefinder 24 can be electrically connected to the first drive in the pressure head 21 for feedback, thereby automatically controlling the real-time downward displacement of the pressure head 21. In this way, in addition to measuring the distance between the pressure head 21 and the support platform in real time, it can also avoid the problem of the pressure head 21 accidentally displacing too much downward, causing excessive pressure damage to the laptop casing under test.

[0064] In one embodiment, the swing opening and closing mechanism 4 includes a swing drive motor 41, a swing arm 42, and a gripper 43; one end of the swing arm 42 is perpendicularly connected to the output shaft of the swing drive motor 41, and the other end forms a free end that can rotate around the swing drive motor 41; the gripper 43 is disposed in the swing arm 42, can rotate synchronously with the swing arm 42, and can clamp the component to be opened or closed in the device under test.

[0065] Specifically, in combination Figure 2 and Figure 3To further explain, the swing opening and closing mechanism 4 is specifically configured to include a swing drive motor 41, a swing arm 42, and a gripper 43. The swing arm 42 is connected to the swing drive motor 41 and can rotate around the swing drive motor 41. This allows the swing drive motor 41 to be specifically configured as a stepper motor or a servo motor, thereby enabling precise control of the output angle of the swing drive motor 41. Additionally, the gripper 43 is positioned within the swing arm 42 to hold the opening and closing portion of the laptop under test and drive it to rotate synchronously with the swing arm 42, thus achieving the opening of the laptop at a fixed angle.

[0066] The specific arrangement of the aforementioned swing opening and closing mechanism 4 has the advantages of simple structure and precise control over the opening angle of the laptop.

[0067] Of course, the gripper 43 in the swing opening and closing mechanism 4 can also be configured as a suction component, which can be fixedly connected to the opening and closing part of the laptop under test by vacuum adsorption.

[0068] In one embodiment, the rocker arm 42 has a groove 421 extending along its length; the gripper 43 has an adjusting seat 431 that engages with the groove 421 and a gripper head 432 for opening and closing; wherein the adjusting seat 431 can slide to adjust its fixed clamping position in the groove 421; the gripper head 432 has a movable clamping piece and a fixed clamping piece, and the movable clamping piece can adjust the clamping distance with the fixed clamping piece.

[0069] Specifically, in combination Figure 3 To further explain, a sliding groove 421 extending along its length is provided in the swing arm 42, and the gripper 43 has an adjusting seat 431 that engages with the sliding groove 421. In this way, the gripper 43 can adjust its relatively fixed installation position in the swing arm 42 by adjusting the adjusting seat 431, so that the gripper 43 can more flexibly adapt to clamping the opening and closing parts in the test equipment of different sizes and models. Moreover, the gripper 43 also has a gripper head 432 for opening and closing clamping. The gripper head 432 can be, but is not limited to, driven by a cylinder. The cylinder drives the movable clamping piece in the gripper head 432 to move toward or away from the fixed clamping piece, so as to realize the function of gripping or releasing the gripper head 432.

[0070] The specific arrangement of the aforementioned rocker arm 42 and gripper 43 has the advantages of simple structure and flexible adjustment to adapt to different sizes of components to be opened and closed.

[0071] In one embodiment, the clamping mechanism 3 includes a lifting clamping head 31 and a lifting driver 32; the lifting clamping head 31 is vertically and horizontally disposed on the test platform 1; the lifting driver 32 is connected to the lifting clamping head 31 for driving the lifting clamping head 31 to move vertically, and to drive the lifting clamping head 31 to rotate around the lifting direction and / or translate along the test platform 1.

[0072] Specifically, in combination Figure 4 To further explain, multiple clamping mechanisms 3 can be specifically provided on the test platform 1, for example, multiple clamping mechanisms 3 can be arranged in a rectangular array around the periphery of the device under test. In addition, the clamping mechanism 3 is specifically configured to include a lifting clamping head 31 and a lifting driver 32. Moreover, the lifting driver 32 is configured to not only drive the lifting clamping head 31 to move up and down, but also to drive the lifting clamping head 31 to rotate around the lifting direction and / or translate along the test platform 1. In this way, when the clamping mechanism 3 resets, the lifting clamping head 31 can be driven to rise to a certain height by the lifting driver 32, and then the lifting clamping head 31 can be driven to rotate or move away from the device under test, so that the device under test is no longer clamped and limited by the clamping mechanism 3. Similarly, when the clamping mechanism 3 needs to clamp and limit the device under test, it is only necessary to first drive the lifting clamping head 31 to rotate or move towards the device under test by the lifting driver 32, and then drive the lifting clamping head 31 to descend and press the device under test by the lifting driver 32.

[0073] Furthermore, the aforementioned lifting driver 32 can be specifically, but not limited to, configured as a "cylinder + drive motor" configuration, using the cylinder to drive the lifting clamp head 31 to rise or fall, and using the drive motor to drive the lifting clamp head 31 to rotate or move.

[0074] The specific arrangement of the clamping mechanism 3 described above has the advantages of simple structure, effective clamping and limiting of the device under test, and flexible release of the device under test.

[0075] In one embodiment, the lifting support mechanism 5 includes a supporting rubber seat 51 and a second lifting driver 52; the supporting rubber seat 51 is vertically and interlockingly disposed on the bottom side of the test platform 1; the second lifting driver 52 is connected to the supporting rubber seat 51 for driving the supporting rubber seat 51 to rise and extend out of the test platform 1, or to descend and retract into the test platform 1.

[0076] Specifically, in combination Figure 5To further explain, the lifting support mechanism 5 is specifically configured to include a supporting rubber seat 51 and a second lifting driver 52. The supporting rubber seat 51 is vertically and interlockingly disposed on the test platform 1, and can rise and extend out of the test platform 1 or descend and retract into the test platform 1 under the drive of the second lifting driver 52. Firstly, through the elastic deformation capability of the supporting rubber seat 51 itself, the lifting and lowering movement of the device under test can be made more stable, avoiding collisions. Moreover, the second lifting driver 52 can be, but is not limited to, a telescopic cylinder, which drives the supporting rubber seat 51 to move up and down accordingly through the telescopic movement of the cylinder.

[0077] The specific arrangement of the above-mentioned lifting support mechanism 5 has the beneficial effects of simple structure and stable vibration damping to drive the lifting and lowering movement of the device under test.

[0078] In one embodiment, the gravity load mechanism 6 includes a load drive motor 61, a load arm 62, and a load pressure head 63; one end of the load arm 62 is connected to the output shaft of the load drive motor 61, and the other end forms a free end that can rotate around the load drive motor 61; the load pressure head 63 is disposed on the load arm 62, can rotate synchronously with the load arm 62, and can be directed toward the actual pressure load on the device under test.

[0079] Specifically, in combination Figure 4 To further explain, the gravity load mechanism 6 is specifically configured to include a load drive motor 61, a load arm 62, and a load pressure head 63. The load drive motor 61 can be, but is not limited to, a stepper motor, which controls the output step angle to drive the load arm 62 to rotate at a fixed angle. The load pressure head 63 can be an electromagnetic adsorption type, which uses electromagnetic control to release pressure or adsorb depressurization. When the gravity load mechanism 6 needs to perform the load pressurization function, it simply needs to drive the load arm 62 and the load pressure head 63 together to the required angle position via the load drive motor 61, and then release the load pressure head 63 accordingly. When the load pressurization function ends, it simply needs to drive the load arm 62 and the load pressure head 63 to rotate in the opposite direction to the initial angle position via the load drive motor 61, and then adsorb the load pressure head 63 accordingly.

[0080] The specific arrangement of the gravity load mechanism 6 described above has the advantages of simple structure and the ability to flexibly and quickly apply load pressure.

[0081] In one embodiment, the load arm 62 has an adjustment groove 621 extending along its own length direction; the load head 63 is fitted into the adjustment groove 621 and can slide to adjust its fixed position in the adjustment groove 621.

[0082] Specifically, in combination Figure 4To further explain, an adjustment groove 621 extending along its length is provided in the load arm 62, and the load pressure head 63 is clamped in the adjustment groove 621. The fixed clamping position of the load pressure head 63 in the adjustment groove 621 can be adjusted by sliding the load arm 62 to rotate via the load drive motor 61. The angle and orientation of the load pressure head 63 can be adjusted by sliding along the adjustment groove 621. This allows for more flexible adjustment of the clamping position of the load pressure head 63, further improving the loading test range of the gravity load mechanism 6.

[0083] In one embodiment, the pressing test device provided in this disclosure further includes an electronic control center; the electronic control center is electrically connected to the pressing mechanism 2, the clamping mechanism 3, the swing opening and closing mechanism 4, the lifting support mechanism 5, and the gravity load mechanism 6, respectively.

[0084] The electronic control center can be specifically, but not limited to, a CPU. The CPU automatically controls the working state of the pressing mechanism 2, the clamping mechanism 3, the swing opening and closing mechanism 4, the lifting support mechanism 5, and the gravity load mechanism 6, so that the pressing test device provided in this embodiment can automatically perform the pressing test function of the device under test.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0086] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
