It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] This invention provides a drop testing device that can be used for drop testing of electronic products such as mobile phones, watches, tablets, and laptops.

[0030] like Figure 1 As shown, the drop test device provided in this embodiment of the invention includes: Falling platform 1; Detection component 2, which is located at the detection station and is used to detect the product to be tested; Positioning component 3 is located at a positioning station and is electrically connected to the detection component 2. The positioning component 3 can adjust the position and orientation of the product under test based on the detection data of the detection component 2. The drop component 4 is located at the drop station. The drop component 4 includes a pickup part 41 facing the drop platform 1. The pickup part 41 is used to pick up the product to be tested and move the product to be tested to a predetermined height before releasing the product to be tested. The transport component 5 is used to transfer the product under test between the drop platform 1, the positioning component 3 and the picking unit 41.

[0031] like Figure 1 As shown, the drop platform 1 is usually located at the bottom of the testing equipment and directly below the drop station, so that the product under test can fall onto the drop platform 1.

[0032] In one embodiment, the drop platform 1 may be equipped with sensors such as an acceleration sensor and an impact sensor to collect drop impact data in real time and upload it to the control component of the test equipment.

[0033] In one embodiment, the drop platform 1 may be provided with limiting edges around its perimeter to prevent the product under test from deviating from the test area when it falls.

[0034] like Figure 1 As shown, the detection component 2 is located at the detection station and is used to inspect the appearance, dimensions, and initial state of the product to be tested. The detection component 2 includes, but is not limited to, an industrial camera, a light source assembly, and a distance sensor, which can be mounted on a detection bracket and oriented toward the placement position of the product to be tested, such as the drop platform 1.

[0035] In one embodiment, the positioning component 3 may include a three-axis moving platform and a rotary drive. The three-axis moving platform can realize translational adjustment in the X / Y / Z directions, while the rotary drive can realize angle adjustment such as horizontal and pitch, so as to adjust the product to be tested on the positioning stage 31 to a suitable position and posture.

[0036] The detection component 2 can be connected to the control component for communication, so that the detection component 2 can transmit data such as the size, appearance and placement posture of the product to be tested to the positioning component 3 in real time through the control component, providing a basis for the position and posture adjustment of the positioning component 3.

[0037] After receiving the detection data from the detection component 2, the positioning component 3 can adjust itself in conjunction with the built-in stored data to make the product under test reach the preset test posture, thereby ensuring the reliability and controllability of the test, and also ensuring the consistency of drop angle and position in batch product testing.

[0038] like Figure 1As shown, the drop test component 4 may include a pickup unit 41 and a lifting drive assembly. The pickup unit 41 may be a pneumatic gripper or a vacuum nozzle, and it faces the drop test platform 1 to pick up the product to be tested. The lifting drive assembly may be a servo motor and a ball screw drive, used to drive the pickup unit 41 to move up and down along a vertical guide rail to facilitate the drop test.

[0039] The pickup unit 41 can pick up the product under test and lift it to a predetermined height, and then reliably release it, so that the product under test can fall to the drop platform 1 with a predetermined acceleration. This avoids the drop trajectory being affected by factors such as clamping interference and release jamming, ensures standardized test conditions, and helps to improve the accuracy and reliability of test data.

[0040] like Figure 1 As shown, the handling component 5 can be a multi-axis robotic arm, which is used to transfer the product under test between the drop platform 1, the positioning component 3, and the picking unit 41. This eliminates the need for frequent manual handling, transfer, and alignment, helping to reduce human intervention, improve the continuity and efficiency of the testing process, and avoid positional errors, posture errors, and safety hazards caused by human operation.

[0041] Therefore, the drop testing equipment of the present invention, through its integrated design of detection, positioning, drop, and handling, enables the calibration of the position and orientation of the product under test. This facilitates continuous drop testing of products of different sizes and shapes, with controllable drop height and angle, which helps improve the reliability and consistency of the test, as well as the efficiency and data reliability of the drop test. Furthermore, the high degree of automation of this testing equipment reduces manual intervention, lowers labor costs, and contributes to improving testing efficiency and quality.

[0042] The detection component 2 pre-detects the product under test, which can obtain the actual position and posture information of the product under test. The positioning component 3 can adjust the position and posture of the product under test based on these detection data, so as to avoid the problem of inconsistent drop posture caused by the placement deviation of the product under test. This helps to improve the repeatability and reliability of drop test and ensure that the test results truly reflect the drop resistance performance of the product under test.

[0043] Optionally, the drop device 4 further includes a frame 42 and a first drive source 43. The first drive source 43 is disposed on the frame 42, and the drive end of the first drive source 43 is connected to the pickup unit 41 and can drive the pickup unit 41 to perform lifting and lowering movements.

[0044] like Figure 3As shown, the frame 42, which is also the main support structure of the drop component 4, includes, but is not limited to, a combination of a motor and a synchronous belt, a cylinder and a cylinder connecting rod. For example, the pickup part 41 can be mounted on the synchronous belt, so that the motor can drive the synchronous belt and the pickup part 41 to move up and down together; or the pickup part 41 can be mounted on the telescopic rod, so that the cylinder can drive the telescopic rod and the pickup part 41 to move forward and backward together, and the direction of the forward and backward movement is the vertical direction.

[0045] Thus, the first drive source 43 can drive the pickup unit 41 to move the product under test to a predetermined height, and then reliably release it so that the product under test can fall onto the drop platform 1 with a predetermined acceleration.

[0046] Optionally, the drop component 4 further includes a floating part 44, which is connected to the frame 42 and detachably connected to the pickup part 41.

[0047] like Figure 3 As shown, the floating part 44 has flexibility or fine-tuning capability, which can provide flexible support and attitude fine-tuning for the pickup part 41, avoiding rigid contact between the pickup part 41 and the frame 42. The floating part 44 can absorb the vibration and impact of the pickup part 41 during the rising, positioning and release process, reduce stress concentration from the rigid transmission belt 414, reduce wear on the drive components, guide rails and connecting structures, thereby improving the operational stability and structural durability of the entire drop component 4.

[0048] Since the pickup unit 41 and the floating unit 44 are detachably connected, when the drop test triggers the release action, the pickup unit 41 can quickly detach from the floating unit 44. This avoids the rigid structure of the frame 42 from having a pulling, interference, or damping effect on the pickup unit 41, so that the product under test is only subject to gravity after release, achieving a near-ideal free fall, which helps to improve the accuracy and repeatability of the drop test.

[0049] Furthermore, thanks to the flexible adjustment capability of the floating part 44, the testing equipment can also be adapted to products with different shapes, weights and surface characteristics, without the need for frequent changes of fixtures or adjustments to the mechanical structure. This helps to expand the applicability of the testing equipment and enhance its versatility and practicality.

[0050] Optionally, the floating part 44 includes a first substrate 441, a second substrate 442, a first connector 443, and a second connector 444. The first substrate 441 is connected to the frame 42. The first substrate 441 has a first through hole, and the second substrate 442 has a second through hole. The first connector 443 passes through the first through hole and the second through hole and floats the second substrate 442 to the first substrate 441. The second connector 444 is connected to the side of the second substrate 442 away from the first substrate 441 and is detachably connected to the pickup part 41.

[0051] like Figure 3 and Figure 4 As shown, the first substrate 441 and the second substrate 442 can be plate-shaped structures such as rectangular plates or circular plates, so that the floating part 44 itself has a certain strength. The first substrate 441 is fixedly connected to the frame 42 to serve as a support platform for the floating part 44. The second substrate 442 is used to detachably connect the pickup part 41. When the drop test triggers the release action, the pickup part 41 can quickly detach from the second substrate 442 to facilitate the drop test.

[0052] like Figure 4 As shown, the first connector 443 can be connected to the inner wall of the second through hole of the second substrate 442 through the first through hole of the first substrate 441, and one end of the first connector 443 is movably connected to the first substrate 441, while the other end of the first connector 443 is fixedly connected to the second substrate 442. This allows the first connector 443, the second substrate 442, and the pickup part 41 to float up and down or rotate together within the first through hole of the first substrate 441, forming a floating connection between the second substrate 442 and the first substrate 441. This allows for fine-tuning of the posture of the pickup part 41 connected to the second substrate 442 and also avoids rigid contact between the pickup part 41 and the frame 42.

[0053] The first connector 443 may have a third external thread at one end and a third internal thread on the inner wall of the second through hole. The third external thread and the third internal thread are threaded together to form a fixed connection between the first connector 443 and the second substrate 442.

[0054] In one embodiment, the other end of the first connector 443 may have a first rough section, and the first through hole may be a smooth hole. In this case, the gap fit between the first rough section and the smooth hole can be used to form a floating connection between the second substrate 442 and the first substrate 441, so that the floating part 44 has a fine adjustment capability. Moreover, the first rough section on the first connector 443 can also provide some resistance to the floating of the second substrate 442, preventing it from becoming unbalanced.

[0055] In one embodiment, the other end of the first connector 443 can be configured as a smooth rod, and the first through hole can have a second rough section. In this case, the gap fit between the second rough section and the smooth rod can be used to form a floating connection between the second substrate 442 and the first substrate 441, so that the floating part 44 has a fine-tuning capability. Moreover, the second rough section of the first through hole can also provide some resistance to the floating of the second substrate 442, preventing it from becoming unbalanced.

[0056] In one embodiment, the first connector 443 may include a blocking segment and a connecting segment. One end of the connecting segment is connected to the blocking segment, and the other end of the connecting segment passes through a first through hole and connects to a second through hole. The projected area of ​​the blocking segment on the first substrate 441 is larger than the area of ​​the first through hole, so that the blocking segment can block the other end of the first connector 443 and prevent it from moving axially. The blocking segment and the connecting segment can be formed separately and then connected, or they can be formed as a single piece.

[0057] A spring can be fitted onto the connecting section, with one end of the spring abutting against the blocking section and the other end of the spring abutting against the second substrate 442. This allows the deformation of the spring to enable a floating connection between the second substrate 442 and the first substrate 441, giving the floating part 44 a fine-tuning capability.

[0058] Optionally, the floating part 44 further includes a first rotating post 445, the first substrate 441 has a third through hole, the second substrate 442 has a fourth through hole, the first rotating post 445 passes through the third through hole and the fourth through hole, and the first rotating post 445 has a first external thread, the third through hole has a first internal thread, and the first external thread is threadedly connected to the first internal thread.

[0059] like Figure 4 As shown, the first rotating post 445 can be connected to the inner wall of the fourth through hole of the second substrate 442 through the third through hole of the first substrate 441, and one end of the first rotating post 445 can be fixedly connected to the first substrate 441 by thread engagement, while the other end of the first rotating post 445 can be movably connected to the second substrate 442, so as to limit the rotation angle of the second substrate 442 and prevent it from floating and becoming unbalanced.

[0060] In one embodiment, the other end of the first rotating post 445 may be provided with a third rough section and the fourth through hole may be a smooth hole. In this case, the clearance fit between the third rough section and the smooth hole, as well as the third rough section of the first rotating post 445, can be used to form a certain obstruction to the rotation of the second substrate 442.

[0061] In one embodiment, the other end of the first rotating post 445 can be set as a smooth rod, and the inner wall of the fourth through hole has a fourth rough section. In this case, the fourth rough section and the smooth rod can be used to form a certain obstruction to the rotation of the second substrate 442 by means of the clearance fit between the fourth rough section and the smooth rod, and the fourth rough section of the fourth through hole.

[0062] Optionally, the first rotating post 445 is clearance-fitted with the fourth through hole.

[0063] In this way, the first connector 443, the second substrate 442, and the pickup part 41 can float up and down or rotate together within the first through hole of the first substrate 441, forming a floating connection between the second substrate 442 and the first substrate 441. This allows for fine-tuning of the posture of the pickup part 41 connected to the second substrate 442 and avoids rigid contact between the pickup part 41 and the frame 42. Furthermore, the small gap between the first rotating post 445 and the fourth through hole can also provide some resistance to the floating of the second substrate 442, preventing it from becoming unbalanced.

[0064] Optionally, the floating part 44 further includes a second rotating post 446, the first substrate 441 has a fifth through hole, the first connector 443 has a sixth through hole, the first rotating post 445 passes through the fifth through hole and the sixth through hole, and the second rotating post 446 has a second external thread, the sixth through hole has a second internal thread, and the second external thread is threadedly connected to the second internal thread.

[0065] like Figure 4 As shown, the second rotating post 446 can pass through the sixth through hole of the first connector 443 and the fifth through hole of the first substrate 441, and one end of the second rotating post 446 is fixedly connected to the first connector 443 by thread engagement, while the other end of the second rotating post 446 is movably connected to the first substrate 441, so as to limit the rotation angle of the first connector 443 and prevent it from floating and becoming unbalanced.

[0066] In one embodiment, the other end of the second rotating post 446 may be provided with a fifth rough section and the fifth through hole may be a smooth hole. In this case, the clearance fit between the fifth rough section and the smooth hole, as well as the fifth rough section of the second rotating post 446, can be used to form a certain obstruction to the rotation of the first connecting member 443.

[0067] In one embodiment, the other end of the second rotating post 446 can be set as a smooth rod, and the fifth through hole has a sixth rough section. In this case, the clearance fit between the sixth rough section and the smooth rod, as well as the sixth rough section of the fifth through hole, can be used to form a certain obstruction to the rotation of the first connecting member 443.

[0068] Optionally, the second connector 444 is an electromagnet, and when the electromagnet is de-energized, the second connector 444 separates from the pickup part 41.

[0069] like Figure 4 As shown, the second connector 444 can be configured as an electromagnet. When energized, the electromagnet can stably attract the pickup unit 41, achieving reliable connection and follow-up lifting. After moving to a predetermined height, the electromagnet can be de-energized, and the magnetic force will quickly disappear, causing the second connector 444 to instantly separate from the pickup unit 41 and fall. This avoids mechanical jamming, pulling, or damping interference, ensuring that the product under test falls in a near-ideal free-fall state, which helps improve the accuracy and consistency of the test results.

[0070] Among them, electromagnets can achieve adsorption and separation control simply by switching on and off electricity. They have fast response speed, small action delay, are easy to integrate with the control components of test equipment, and do not require complex mechanical transmission or pneumatic and hydraulic structures. The overall control logic is simple, the operation is highly stable, and it is conducive to improving the test cycle and overall test efficiency.

[0071] In addition, the electromagnet can be de-energized to instantly separate the second connector 444 from the pickup part 41 without rigid impact or violent mechanical action. This reduces the vibration and impact on the test equipment frame 42, lifting mechanism and the product under test at the moment of separation, which helps to protect the appearance and internal structure of the product under test and can also extend the service life of the test equipment.

[0072] Optionally, the drop-off component 4 further includes a buffer 45, which is disposed on the frame 42 and located below the pickup part 41.

[0073] like Figure 3 As shown, when the pickup unit 41 releases the product to be tested and falls, the buffer unit 45 located below the pickup unit 41 can provide flexible support and deceleration buffer for the pickup unit 41, avoiding direct impact between the pickup unit 41 and the frame 42 or other rigid structures, which would cause damage to the pickup unit 41. This helps to reduce impact load and mechanical vibration, protect the pickup unit 41 and related transmission components, and extend the service life of the testing equipment.

[0074] The buffer 45 is flexible, which can replace rigid contact with flexible buffer, reduce the impact noise generated when the pickup 41 falls, make the test equipment operate more quietly, help optimize the on-site test environment, and meet the design requirements of low-noise automated equipment.

[0075] In addition, the buffer section 45 located below the pickup section 41 can also serve as a mechanical limiting structure for the pickup section 41, thereby limiting the downward limit position of the pickup section 41 and preventing damage to components caused by the pickup section 41 exceeding its stroke due to control abnormalities or drive failures. This helps to improve the operational safety and stability of the testing equipment.

[0076] Optionally, the pickup unit 41 includes a main body 411 and two clamping members 412, the two clamping members 412 being movably connected to the main body 411 and capable of relative movement.

[0077] like Figure 5 As shown, the two clamping components 412 can move relative to each other and open and close, enabling them to clamp and release the product under test from both sides. This helps ensure that the product under test does not shift, shake, or fall off during movement, ensuring a stable initial drop posture and improving the reliability of the testing process. The clamping components 412 include, but are not limited to, grippers, clamping arms, and suction cups.

[0078] The symmetrical clamping method using two clamping components 412 with relative motion allows the clamping force applied to the product under test to be symmetrically distributed. This avoids problems such as tilting or twisting of the product under test caused by unilateral force, helps to ensure that the product under test has a consistent posture in the clamping state, and can improve the repeatability and accuracy of drop tests.

[0079] In one embodiment, the relative movement of the two clamping members 412 can be synchronously controlled by a single drive source, enabling them to open and close synchronously. This avoids additional lateral forces or torques caused by asynchronous clamping members 412, ensuring that the product under test (DUT) falls in a near-ideal free-fall state after release, thus helping to reduce DUT positional deviation. Furthermore, the synchronous control logic is simple, easily interfaced with the control components of the testing equipment, simplifies the mechanical structure, reduces the probability of failure, and facilitates the maintenance and debugging of the testing equipment.

[0080] Optionally, the pickup unit 41 further includes a second drive source 413 and a transmission belt 414. The two clamping members 412 are respectively connected to different sides of the transmission belt 414. The drive end of the second drive source 413 is connected to one of the clamping members 412 and can drive the corresponding clamping member 412 to move.

[0081] like Figure 5 As shown, the second drive source 413 can drive the right clamping member 412 to move, and the connected transmission belt 414 can drive the other clamping member 412 to move in the opposite direction synchronously, so that the synchronous opening and closing action of the two clamping members 412 can be achieved. There is no need to configure a separate drive source for each clamping member 412, which helps to reduce the number of drive sources, simplify the overall structure, and also reduce the assembly difficulty and cost of the test equipment.

[0082] Furthermore, the single-sided drive layout formed by the second drive source 413 driving a clamping member 412 is simple, making the overall space occupied by the pickup part 41 small. This allows the pickup part 41 to be more compact and lightweight, making it easier to install and arrange in a limited space. It also reduces the inertia of the pickup part 41 during lifting and lowering, which helps to improve the response speed of the lifting and releasing actions of the pickup part 41.

[0083] The two clamping members 412 are respectively located on different sides of the transmission belt 414. For example Figure 5 One clamping member 412 is connected to the upper side of the transmission belt 414, and the other clamping member 412 is connected to the lower side of the transmission belt 414, so that when the transmission belt 414 moves, the two clamping members 412 on it can move in opposite directions synchronously, such as synchronously approaching or synchronously moving away, thereby realizing the synchronous opening and closing action of the two clamping members 412.

[0084] In this way, the two clamping parts 412 can achieve reverse synchronous movement through the transmission belt 414, and the movement speed and displacement of the two clamping parts 412 are consistent, which can avoid problems such as asynchronous movement of the clamping parts 412 on both sides and clamping eccentricity. This can ensure that the pickup part 41 clamps the product to be tested in the center, which helps to improve the consistency of the initial posture of the drop and the test accuracy.

[0085] The power transmission is carried out by a transmission belt 414, which is continuous and smooth. There is no impact or jamming from the rigid transmission belt 414 such as gears and connecting rods. This makes the opening and closing process of the clamping part 412 smooth, which can reduce the vibration or posture disturbance of the product under test, and help protect the product under test and ensure the stability of the test.

[0086] By adjusting the stroke of the transmission belt 414 or the motion parameters of the second drive source 413, the opening and closing range of the two clamping parts 412 can be flexibly changed to adapt to products of different sizes and shapes, which helps to improve the versatility of the testing equipment.

[0087] Optionally, the pickup unit 41 further includes a push plate 415, which is fixedly connected to one of the clamping members 412, and the second drive source 413 is a cylinder, the extension and retraction end of which is connected to the push plate 415.

[0088] like Figure 5 As shown, when the cylinder extends, the cylinder pushes the right clamping member 412 to move to the right through the push plate 415. The right clamping member 412 drives the synchronous belt to move clockwise, and the synchronous belt can drive the left clamping member 412 to move to the left, so as to realize the synchronous opening of the two clamping members 412, that is, the release of the pickup part 41.

[0089] When the cylinder retracts, the cylinder pulls the right clamping member 412 to the left through the push plate 415. The right clamping member 412 drives the synchronous belt to move counterclockwise, and the synchronous belt can drive the left clamping member 412 to move to the right, so as to realize the synchronous closure of the two clamping members 412, that is, the clamping of the pickup part 41.

[0090] like Figure 5 As shown, the pickup unit 41 also includes a guide rail 416, which is disposed on the main body 411, and the extension direction of the guide rail 416 is consistent with the movement direction of the clamping member 412. The two clamping members 412 can move along the guide rail 416 and realize synchronous opening and closing actions, which helps to ensure the reliability of the movement of the clamping member 412.

[0091] Optionally, it also includes an adjustment component 6, which is located near the drop platform 1 and is used to adjust the position of the product under test located on the drop platform 1.

[0092] like Figure 6 As shown, the product under test is often scattered after being dropped. By adjusting component 6, it can be quickly placed into the preset position, which makes it easy for the handling component 5 to stably grasp and transfer it to the positioning component 3. This avoids grasping failure due to product offset or tipping, and helps to ensure the continuous and smooth automated testing process.

[0093] Among them, the adjustment component 6 can adjust the product under test on the drop platform 1 to a preset posture and position, so that the reference of subsequent handling, positioning, drop and other processes remains consistent, reducing the positioning error caused by the messy position of the product, thereby improving the repeatability and data reliability of multiple tests.

[0094] Among them, the adjustment component 6 can also adaptively adjust its action according to the size and shape of the product under test, and can achieve position correction for products with regular or irregular shapes, which helps to expand the applicability of the testing equipment and enhance its overall practicality.

[0095] Optionally, it also includes a control component, which is electrically connected to the detection component 2 and the positioning component 3, respectively. The control component can control the positioning component 3 to adjust the position and orientation of the product under test based on the detection data of the detection component 2.

[0096] Specifically, the detection component 2 can be connected to the control component, and the positioning component 3 can be connected to the control component for communication, so that the detection component 2 can transmit data such as the size, appearance, and placement posture of the product to be tested to the control component in real time.

[0097] After receiving the detection data from the detection component 2, the control component can combine the built-in stored data to control the positioning component 3 to make corresponding adjustments so that the product under test reaches the preset test posture, thereby ensuring the reliability and controllability of the test, and also ensuring the consistency of drop angle and position in batch product testing.

[0098] Optionally, the detection component 2 is electrically connected to the transport component 5 through the control component, so that the control component can plan the movement path of the transport component 5 based on the detection data of the detection component 2.

[0099] Optionally, the positioning component 3 includes at least one positioning platform 31 and at least one positioning element 32, with each positioning platform 31 having a positioning element 32, the positioning element 32 being used to adjust the position of the product to be tested located on the corresponding positioning platform 31.

[0100] like Figure 2 As shown, the positioning platform 31 provides a flat and reliable support benchmark for the product under test, preventing tilting or slippage during posture adjustment. The positioning component 32 can act on the outside of the product under test and constrain and correct its placement, enabling the product under test to quickly reach the preset test benchmark and posture, providing a uniform initial state for subsequent drop tests and helping to ensure consistency and comparability of multiple tests.

[0101] The positioning component 3 includes at least one positioning stage 31 and a corresponding positioning element 32, which can meet the continuous testing of a single product under test, or can be expanded into a combination of multiple positioning stages 31 and positioning elements 32 according to the test cycle, so as to realize the parallel positioning and correction of multiple products under test, effectively improve the overall testing efficiency of the testing equipment, and adapt to different production capacities and testing scenarios.

[0102] The positioning stages 31 and positioning components 32 in different groups can have different sizes and structures, so that the positioning stages 31 and positioning components 32 in different groups can adapt to the position adjustment of products of different sizes or types.

[0103] Each positioning stage 31 is configured with an independent positioning element 32, which makes the working area between multiple positioning stages 31 clear and their actions do not interfere with each other. In terms of control, multiple positioning elements 32 can be driven independently or synchronously. The control logic is simple and clear, and it can also avoid interference problems between multiple products under test and multiple adjustment mechanisms, reduce the probability of failure, and improve the stability and reliability of the posture adjustment process.

[0104] like Figure 2As shown, the positioning member 32 may include multiple blocks disposed on the positioning stage 31. The multiple blocks are located on different edges of the positioning stage 31. The multiple blocks can move independently and adjust the position of the product to be tested placed on them, so that the conveying component 5 can grasp the center of gravity of the product to be tested.

[0105] Optionally, the positioning component 3 includes at least one flipping component 33, which is used to flip the product under test to adjust the posture of the product under test.

[0106] like Figure 2 As shown, the flipper 33 can flip the product under test and adjust it to different orientations and angles according to the test requirements, so as to meet the drop test requirements of the product under test from multiple angles and angles, so that the drop test can cover more comprehensive working conditions and help improve the integrity and reference value of the test results.

[0107] The flipping component 33 can automatically complete the flipping correction of the product under test based on the position and posture information fed back by the detection component 2, without the need for manual flipping or adjustment. This ensures that the initial posture of the product under test is consistent before each drop, which helps improve the repeatability and reliability of the test results. It also avoids posture deviations, inefficiencies, and safety hazards caused by human factors, realizing full automation of the feeding, detection, positioning, flipping, and drop processes, which helps improve the overall testing efficiency.

[0108] The flipping component 33 can work in conjunction with the positioning stage 31 and the positioning component 32. The positioning component 32 completes the planar position correction, and the flipping component 33 realizes the angle and posture adjustment. Together, they form a multi-dimensional posture adjustment mechanism, which helps to improve the positioning accuracy of the product under test and provides a reliable guarantee for high-precision drop testing.

[0109] Each positioning stage 31 is equipped with a flipping component 33, which enables the flipping component 33 to be linked with the positioning component 32 on the corresponding positioning stage 31, and to realize the position and posture adjustment of products of different sizes or types.

[0110] like Figure 1 As shown, it also includes a first storage component 7, which is used to store the product to be tested before and after the test.

[0111] like Figure 1 As shown, it also includes a second storage component 8, which has multiple carrier platforms, each carrier platform having a pick-up head. When testing different products to be tested, the conveying component 5 can move to the second storage component 8 and replace the pick-up head accordingly.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.
