[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0034] Traditional battery drop testing relies on manually carrying the battery cell to a specified height and then releasing it. However, battery drop testing requires repeated drops to verify reliability. However, the chemical state of battery cells during the R&D phase is unstable, and the impact of a drop can cause leakage, fire, or even explosion. Even with protective equipment, operators still face significant risks.

[0035] To this end, some manufacturers have gradually adopted automated equipment to replace manual labor, but the following defects are common in actual application:

[0036] (1) Single function: The automation equipment in related technologies only supports vertical drop (Z-axis) and cannot meet the requirements of horizontal or tilt angle testing (such as simulating side drop or upside-down drop of battery cells);

[0037] (2) Dependence on manual intervention: The automated equipment in related technologies requires manual clamping of battery cells and adjustment of posture. After testing, the battery cells need to be manually recovered and repositioned, which is inefficient and interrupts the continuity of the experiment.

[0038] (3) Insufficient positioning accuracy: The automation equipment in related technologies lacks a multi-axis linkage mechanism, which makes it difficult to ensure the consistency of the height and angle of each drop, affecting the comparability of experimental data.

[0039] The above problems seriously restrict the efficiency and accuracy of battery cell safety testing, becoming a key bottleneck in the power battery R&D cycle.

[0040] Therefore, reference Figure 1 As shown, an embodiment of the present invention provides an automatic drop test device 1, which includes a frame 100 and a gripping mechanism 200; the gripping mechanism 200 is connected to the frame 100 for gripping or releasing the test piece, and the gripping mechanism 200 can adjust the posture of the test piece.

[0041] During the drop test, the test piece is first placed on the clamping mechanism 200, and the clamping mechanism 200 can adjust the posture of the test piece, that is, it can change the horizontal inclination angle or vertical angle of the test piece, so that the test piece meets the testing requirements of national standards, enterprise standards and special research and development, and the test accuracy is high.

[0042] In some embodiments, reference Figure 1 and Figure 2 As shown, the automatic drop test device 1 further includes a moving mechanism 300, which is connected between the frame 100 and the gripping mechanism 200 to drive the gripping mechanism 200 to move. In this embodiment, the moving mechanism 300 is configured to be movable in three directions.

[0043] When the test piece has finished falling once, the gripping mechanism 200 can be moved by the moving mechanism 300 so that the gripping mechanism 200 can grip the test piece again and repeat the falling and picking process. In the above drop test process, the process of manual recovery and repositioning and installation can be avoided. The drop test is efficient, reduces operational risks, and avoids the possibility of injury to the operator.

[0044] In addition, through the cooperation of the hand clamping mechanism 200 and the moving mechanism 300, the consistency of the drop height and angle each time can be ensured, thereby ensuring the comparability of the drop test results.

[0045] It can be understood that, in this embodiment, the frame 100 adopts a gantry frame structure.

[0046] In some embodiments, reference Figure 1 and Figure 2 As shown, the gripping mechanism 200 includes a clamp assembly 210 and an adjustment assembly 220. The clamp assembly 210 is connected to the moving mechanism 300 and is used to clamp or release the test piece. The adjustment assembly 220 is connected to the clamp assembly 210 to adjust the posture of the test piece. It should also be noted that, in this embodiment, the posture of the test piece includes a horizontal posture and a vertical posture. The horizontal posture is the horizontal tilt angle of the test piece, and the vertical posture is the rotation angle of the test piece. Thus, by setting the adjustment assembly 220, the automatic drop test equipment 1 has the ability to adjust the posture, that is, it can meet a variety of test requirements, such as national standards, enterprise standards and special research and development requirements. By flexibly adjusting the posture of the test piece, different falling scenarios can be simulated, thereby improving the comprehensiveness and accuracy of the test.

[0047] In some embodiments, reference Figure 1 and Figure 2As shown, the clamp assembly 210 includes a driver 211, a first clamping plate 212, and a second clamping plate 213. The driver 211 is connected to the moving mechanism 300. The first clamping plate 212 and the second clamping plate 213 are both connected to the driver 211. The driver 211 is used to drive the first clamping plate 212 and the second clamping plate 213 to move toward or away from each other to achieve the clamping or release of the test piece. Accordingly, the driver 211 can accurately control the movement of the first clamping plate 212 and the second clamping plate 213 toward or away from each other, thereby achieving the clamping and release of the test piece, improving the accuracy and reliability of the clamping and release, while reducing the difficulty and risk of operation.

[0048] It is understandable that, referring to Figure 1 and Figure 2 As shown, the size and dimensions of the first clamping plate 212 and the second clamping plate 213 can be adjusted according to the size and shape of the test piece to be clamped, so as to ensure stability and firmness during clamping. The first clamping plate 212 and the second clamping plate 213 can also apply force evenly to avoid damage or falling of the test piece due to uneven clamping force. It should be further explained that in this embodiment, the clamp assembly 210 is configured as a pneumatic clamp. The pneumatic clamp has the technical effects of fast response, precise control, high reliability, high safety, easy control, and strong adaptability, which can significantly improve the performance and testing efficiency of the equipment.

[0049] In some embodiments, reference Figure 1 and Figure 2 As shown, the adjustment assembly 220 includes a first motor 221 and a second motor 222. The first motor 221 is connected to one of the first clamping plate 212 and the second clamping plate 213 to drive the test piece to rotate with the vertical direction as the axis. The second motor 222 is connected to one of the first clamping plate 212 and the second clamping plate 213 to drive the test piece to rotate with the horizontal direction as the axis. Through the cooperation of the first motor 221 and the second motor 222, the test piece can be rotated in the vertical direction and the horizontal direction, thereby adjusting the horizontal or vertical posture of the test piece, which can meet complex testing requirements, simulate different falling scenarios of the test piece, and also perform multi-angle performance testing on the test piece.

[0050] In addition, refer to Figure 1 and Figure 2 As shown, the horizontal posture or vertical posture of the test piece is adjusted by the first motor 221 and the second motor 222, so that the posture adjustment process is automated, manual intervention is avoided, and the stability and efficiency of the test are improved; and since the posture adjustment process does not require manual operation, it is possible to quickly switch to the desired posture of the test piece, thereby reducing the test time and improving the test efficiency of the test piece.

[0051] In some embodiments, reference Figure 1 and Figure 2 As shown, the rotation range of the first motor 221 is 0° to 360°. In this embodiment, the first motor 221 is used to drive the test piece to rotate about the vertical axis. Therefore, the first motor 221 can realize 360° rotation of the test piece and achieve multi-dimensional posture adjustment in the vertical direction, thereby improving the flexibility, adaptability and accuracy of the test.

[0052] In some embodiments, reference Figure 1 and Figure 2 As shown, the rotation range of the second motor 222 is 0° to 90°. In this embodiment, the second motor 222 is used to drive the test piece to rotate about the horizontal axis. Therefore, the second motor 222 can achieve full rotation of the test piece's tilt angle and achieve multi-dimensional posture adjustment in the horizontal direction, thereby improving the flexibility, adaptability, and accuracy of the test.

[0053] In some embodiments, reference Figure 1 and Figure 2 As shown, the rotation range of the first motor 221 is 0° to 360°; the rotation range of the second motor 222 is 0° to 90°. In this embodiment, the first motor 221 is used to drive the test piece to rotate about the vertical axis. Therefore, the first motor 221 can achieve 360° rotation of the test piece and multi-dimensional posture adjustment in the vertical direction. The second motor 222 is used to drive the test piece to rotate about the horizontal axis. Therefore, the second motor 222 can achieve 360° rotation of the test piece and multi-dimensional posture adjustment in the horizontal direction, thereby improving the flexibility, adaptability, and accuracy of the test.

[0054] It is understandable that in this embodiment, encoders are provided on both the first motor 221 and the second motor 222. Therefore, the first motor 221 and the second motor 222 can cooperate with encoder feedback to achieve a locking state at any angle to ensure that the clamp assembly 210 is adjusted into place.

[0055] In some embodiments, reference Figure 1As shown, the moving mechanism 300 includes an X-axis moving component 310, a Y-axis moving component 320 and a Z-axis moving component 330. The X-axis moving component 310 is arranged on the frame 100 to drive the clamping mechanism 200 to move along the X-axis. The Y-axis moving component 320 is connected to the X-axis moving component 310 to drive the clamping mechanism 200 to move along the Y-axis. The Z-axis moving component 330 is connected to the Y-axis moving component 320 to drive the clamping mechanism 200 to move along the Z-axis, wherein the clamping mechanism 200 is connected to the Z-axis moving component 330. In this embodiment, the gripping mechanism 200 can freely move in three-dimensional space through the cooperation of the X-axis moving assembly 310, the Y-axis moving assembly 320, and the Z-axis moving assembly 330. This allows the gripping mechanism 200 to obtain a full range of spatial adjustment capabilities, enabling the gripping mechanism 200 to reach any position within the rack 100 and simulate various complex drop scenarios. For example, the test piece can be released at different heights, horizontal positions, and vertical positions, thereby meeting the positioning requirements of different test scenarios.

[0056] And, refer to Figure 1 As shown, the X-axis moving assembly 310 , the Y-axis moving assembly 320 and the Z-axis moving assembly 330 can all be independently controlled, enabling precise control of moving distance and speed, thereby ensuring accuracy and repeatability of the test.

[0057] In addition, refer to Figure 1 As shown, through the cooperation of the X-axis moving assembly 310, the Y-axis moving assembly 320 and the Z-axis moving assembly 330, the gripping mechanism 200 can perform multi-point drop tests in a larger test area, and can also repeatedly test at the same position to ensure the accuracy of the test results.

[0058] It should also be noted that, referring to Figure 1 As shown, after a drop test of the test piece is completed, the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 can cooperate to enable the clamping mechanism 200 to quickly move to the drop position of the test piece, and the test piece is clamped by the clamping mechanism 200, and the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 drive the clamping mechanism 200 to move and reset to the original test position, thereby ensuring the accuracy of the test results.

[0059] In some embodiments, the X-axis moving assembly 310 has a movement accuracy of 0.1 mm. In this embodiment, by setting the X-axis moving assembly 310 to a movement accuracy of 0.1 mm, the movement distance and position can be ensured to be consistent for each test, thereby improving the accuracy, adaptability, and repeatability of the test, and enhancing the automation level, test efficiency, reliability, and safety of the device.

[0060] In some embodiments, the Y-axis moving assembly 320 has a movement accuracy of 0.1 mm. In this embodiment, by setting the Y-axis moving assembly 320 to a movement accuracy of 0.1 mm, the movement distance and position can be consistent for each test, thereby improving the accuracy, adaptability, and repeatability of the test, and enhancing the automation level, test efficiency, reliability, and safety of the device.

[0061] In some embodiments, the Z-axis moving assembly 330 has a movement accuracy of 0.1 mm. In this embodiment, by setting the Z-axis moving assembly 330 to a movement accuracy of 0.1 mm, the movement distance and position can be ensured to be consistent for each test, thereby improving the accuracy, adaptability, and repeatability of the test, and enhancing the automation level, test efficiency, reliability, and safety of the device.

[0062] In some embodiments, the movement accuracy of the X-axis moving assembly 310 is 0.1 mm; the movement accuracy of the Y-axis moving assembly 320 is 0.1 mm; and the movement accuracy of the Z-axis moving assembly 330 is 0.1 mm. In this embodiment, by setting the movement accuracy of the X-axis moving assembly 310, the Y-axis moving assembly 320, and the Z-axis moving assembly 330 to 0.1 mm, the movement distance and position can be consistent during each test, improving the accuracy, adaptability, and repeatability of the test, and enhancing the automation level, testing efficiency, reliability, and safety of the equipment.

[0063] It is understandable that in other embodiments, different movement accuracies of the X-axis moving assembly 310, the Y-axis moving assembly 320, and the Z-axis moving assembly 330 can be set according to actual test needs or special test requirements of the enterprise. The X-axis moving assembly 310, the Y-axis moving assembly 320, and the Z-axis moving assembly 330 can be set to have consistent movement accuracies, or the X-axis moving assembly 310, the Y-axis moving assembly 320, and the Z-axis moving assembly 330 can be set to have inconsistent movement accuracies. Adaptive adjustments can be made according to actual usage needs.

[0064] In summary, after a drop process of the test piece is completed, the gripping mechanism 200 can be moved by the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330, so that the gripping mechanism 200 clamps the test piece again and repeats the drop and pick-up process. In the above drop test process, the process of manual recovery and repositioning and installation can be avoided, the drop test efficiency is high, and the operational risk is reduced, avoiding the possibility of injury to the operator.

[0065] In this embodiment, the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 are all configured as gear rack transmission mechanisms, which, in conjunction with the high-precision linear guide rails and sliders provided on the gantry frame, can achieve a positioning accuracy of 0.1 mm for the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 in three-dimensional space, covering a wide range.

[0066] In addition, in this embodiment, referring to Figure 1 As shown, the X-axis moving assembly 310, the Y-axis moving assembly 320 and the Z-axis moving assembly 330 are set to move independently. In other embodiments, the X-axis moving assembly 310, the Y-axis moving assembly 320 and the Z-axis moving assembly 330 can also be set to be linked to ensure full coverage of the test area.

[0067] In some embodiments, reference Figure 3 and Figure 4 As shown, the automatic drop test equipment 1 also includes a positioning mechanism 400, which is connected to the gripping mechanism 200 for real-time identification of the position of the test piece. In this embodiment, the positioning mechanism 400 is configured as a visual positioning mechanism 400, which can obtain the position information of the test piece in real time through visual control, thereby collecting the position and posture information of the test piece in real time, and processing the image data obtained by the visual positioning mechanism 400 by connecting to the computing unit. The remote control terminal generates motion instructions, thereby driving the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 to drive the gripping mechanism 200 to move, and completes the grasping, angle adjustment and dropping of the test piece through the first and second gripping jaws, with high positioning accuracy.

[0068] It should be further explained that, in this embodiment, the visual positioning mechanism 400 is configured as a visual system CCD, which is used to identify the product position in real time, calculate and provide the coordinate data of the first clamping plate and the second clamping plate; of course, in other embodiments, different types of visual positioning mechanisms 400 can be selected according to actual usage needs.

[0069] In other embodiments, the positioning mechanism 400 is not limited to the visual positioning mechanism 400. The positioning mechanism 400 may also adopt a sensor or other structures, as long as it can obtain the position information of the gripping mechanism 200.

[0070] It is understandable that, referring to Figure 3 and Figure 4 As shown, due to the setting of the visual positioning mechanism 400, it can play an auxiliary role for the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330, further ensuring the movement accuracy of the gripper component and ensuring the accuracy of the test.

[0071] In some embodiments, reference Figure 5 As shown, the automatic drop test apparatus 1 further includes a drop platform located below the gripping mechanism 200 for receiving the test piece after it has fallen. In this embodiment, the introduction of the drop platform allows for the reception of the test piece after it has fallen, and the drop platform can be isolated from other operating areas, preventing the operator from coming into contact with the high-speed moving test piece during the test, thereby reducing operational risks.

[0072] In some embodiments, reference Figure 5 As shown, the gripping range of the gripping mechanism 200 covers the drop platform. This ensures that the gripping mechanism 200 can grasp and release at any position on the drop platform, allowing the equipment to perform multiple drop tests at different locations without frequently moving the test piece or adjusting the equipment layout, thereby significantly improving test efficiency.

[0073] In summary, traditional battery drop testing methods rely on manual transport of battery cells to a specified height and then release them freely. Battery drop testing requires repeated battery drop processes to verify reliability. The chemical state of battery cells in the R&D stage is unstable, and the impact of the drop of the battery cells may cause leakage, fire, or even explosion. Even if operators wear protective equipment, they still face extremely high risks.

[0074] Although existing automated equipment can partially replace manual labor, it generally has the following defects:

[0075] (1) Single function: It only supports vertical drop (Z-axis) and cannot meet the requirements of horizontal or tilt angle testing (such as simulating side drop or upside-down drop of battery cells);

[0076] (2) Dependence on manual intervention: The battery cells need to be manually clamped and adjusted, and the battery cells need to be manually recovered and repositioned after the test, which is inefficient and interrupts the continuity of the experiment;

[0077] (3) Insufficient positioning accuracy: The lack of a multi-axis linkage mechanism makes it difficult to ensure the consistency of the height and angle of each drop, affecting the comparability of experimental data.

[0078] If the above problems are serious, they will restrict the efficiency and accuracy of battery cell safety testing and become a key bottleneck in the power battery R&D cycle.

[0079] Therefore, an embodiment of the present invention provides an automatic drop device. In this embodiment, the test piece is a battery cell. During the drop test, the test piece is first placed on the gripping mechanism 200. The visual positioning mechanism 400 can identify the position and posture of the test piece in real time, and the image data obtained by the visual positioning mechanism 400 is processed by the connected computing unit. The remote control terminal generates a motion command to drive the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 to drive the gripping mechanism 200 to move, and through the first gripping claw The first and second clamping jaws are used to adjust the drop position and drop posture of the test piece, so that the test piece can meet the test requirements of national standards, enterprise standards, and special research and development, for example, 30° tilt drop, 45° tilt drop, 60° tilt drop, etc. By introducing the first motor 221 and the second motor 222 as the adjustment component 220, the clamp assembly 210 can achieve multi-dimensional posture adjustment of the test piece in the vertical and horizontal directions, thereby improving the flexibility, adaptability and accuracy of the test, and also enhancing the degree of automation, test efficiency, reliability and safety of the equipment;

[0080] When a drop process of the test piece is completed, the position and posture of the test piece can be identified in real time through the visual recognition mechanism, and the image data obtained by the visual positioning mechanism 400 is processed by the connected computing unit, and the remote control terminal generates a motion instruction, thereby driving the X-axis moving component 310, the Y-axis moving component 320 and the Z-axis moving component 330 to drive the clamping mechanism 200 to move, so that the clamping component 210 picks up the test piece that falls on the drop platform and moves it back to the original drop position, realizing the cyclic process of the drop test of the test piece; in the above-mentioned drop test process, the automatic drop test equipment 1 can avoid the process of manually recovering the test piece after the fall and then repositioning and installing it, avoids the problem of insufficient positioning accuracy caused by manual intervention, ensures the consistency of the drop height and tilt angle each time, and does not require manual intervention in the whole process, avoids manual contact with dangerous batteries, reduces the possibility of safety hazards, and at the same time ensures the drop test efficiency of the test piece and the continuity of the test.

[0081] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
