Description

Technical Field

[0001] This application relates to the field of vacancy detection devices, and in particular to a dynamic vacancy detection device and its detection method. Background Technology

[0002] A vacancy refers to a state or component in the design of a mechanism. Specifically, a vacancy can refer to a position or connection point where, in some cases, a corresponding element or device is installed, or in others, it can be left vacant to allow the corresponding part of the mechanism to move or change freely during movement or operation.

[0003] Taking foldable terminal devices as an example, the hinge of a foldable terminal product has a corresponding "spare space" during the entire folding process. That is, the positions of the various structures connected to the hinge change depending on each other during the folding process. The spare space in the hinge is also an important guarantee for the terminal device to be able to fold.

[0004] However, current foldable terminal products frequently suffer from problems such as poor flattening, jamming, and misalignment. In other words, these foldable terminal products have problems with inadequate detection of hinge misalignment. Summary of the Invention

[0005] This application provides a dynamic misalignment detection device and method, aiming to solve the technical problem of large errors in misalignment detection in current mechanisms.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, this application provides a dynamic misalignment detection device, including a flipping unit, an excitation unit, a measuring unit, and a control unit; wherein, the flipping unit is used to flip a target object; the excitation unit is used to apply a corresponding excitation force to the target object during the flipping process to achieve the flipping of the target object within a certain misalignment value range; the measuring unit is used to measure the displacement change of the target object during the flipping process; and the control unit controls the flipping unit, the excitation unit, and the measuring unit to work together.

[0008] The flipping unit includes a flipping power unit, a flipping platform, a placement platform, and a clamping assembly. The flipping power unit provides the power required to flip the target object. Both the flipping platform and the placement platform are used to place the target object. The flipping platform folds and rotates around the centerline of the output end of the flipping power unit, while the placement platform slides relative to the flipping platform along a first direction perpendicular to the extension direction of the target object's flipping axis. Here, the flipping platform and the placement platform rotate synchronously under the drive of the flipping power unit to flip the target object. Simultaneously, relative sliding occurs between the placement platform and the flipping platform. Specifically, the placement platform slides relative to the flipping platform along the first direction to accommodate the dynamic change in the target object's flipping center during the flipping process. The clamping assembly includes a clamping body mounted on a placement platform and a clamping block rotatably connected to the clamping body. The clamping block is used to clamp the outer edge of the target object and can rotate relative to the clamping body within a preset angle about a second direction. Here, the first direction is perpendicular to the second direction, and the clamping block and the clamping body are rotatably connected, thereby enabling dynamic clamping between the clamping block and the target object. That is, the clamping position of the clamping block on the target object can change accordingly according to the flipping process. Specifically, the clamping block can swing synchronously with the target object during the flipping process. Thus, when the target object is flipped to measure its displacement, the flipping part can adapt to the constantly changing rotation center of the target object and dynamically clamp the target object, thereby improving the accuracy of the measurement process.

[0009] The excitation unit rotates synchronously with the flipping platform. Specifically, the excitation unit includes an excitation power unit and a force acquisition unit. The excitation power unit includes an excitation moving part and an excitation fixing part for driving the excitation moving part toward the target object. Here, the excitation fixing part provides the power for the excitation moving part to abut against the target object, so that the excitation moving part can abut against the target object and maintain within a certain range. At the same time, the force acquisition unit acquires the first displacement of the excitation moving part. The force acquisition unit is electrically connected to the excitation fixing part. The acquired first displacement is also fed back to the excitation fixing part to form a closed-loop control.

[0010] The measuring unit is used to contact the target object to measure the second displacement of the target object during the folding and rotating process.

[0011] Here, the measuring unit should be a sensor, such as a displacement sensor or a force sensor, to measure the second displacement of the target object during the folding and rotating process. Furthermore, the difference between the second displacements after two folding and rotating processes can be used to calculate whether the corresponding false displacement value meets the requirements.

[0012] The control unit is electrically connected in sequence to the flipping power unit, the excitation power unit, the force acquisition unit, and the measurement unit.

[0013] Here, the control unit can be various types of controllers, used to control the flipping angle, speed, and magnitude of the excitation force of the target object, and also to realize the coordinated work between various units.

[0014] The technical solutions described in this application have at least the following technical effects or advantages:

[0015] The dynamic displacement detection device provided in this application operates as follows: a flipping unit drives a target object to fold and rotate. During the folding and rotation, an excitation unit applies an excitation force to the target object, and a measuring unit measures the displacement of the target object during the folding and rotation. The displacement value of the target object is obtained by comparing the displacements of forward and reverse folding. A control unit controls the coordinated operation between the various units. Specifically, the target object is mounted on a placement platform and folds and rotates synchronously with the flipping platform. The placement platform can slide relative to the flipping platform in a first direction to accommodate the dynamic change of the target object's rotation center during folding and rotation. Simultaneously, the clamping block of the clamping unit can rotate within a preset angle relative to the clamping body in a second direction. That is, the clamping assembly and the target object are movably connected, thus eliminating the torsional force exerted by the clamping assembly on the target object and reducing the possibility of damage to the target object. Therefore, the dynamic displacement detection device provided in this application can adapt to the constantly changing rotation center of the target object during folding and rotation, resulting in smaller detection errors and higher accuracy.

[0016] In some embodiments, the clamping assembly includes a clamping body, a rotating part rotatably connected to the clamping body, a clamping block connected to the rotating part, and a reset member connected at both ends to the clamping body and the clamping block respectively. The number of reset members is even, and each reset member is symmetrically arranged in pairs with the rotation center axis of the rotating part as the center of symmetry.

[0017] Understandably, the clamping body is fixed; the rotating part is rotatably connected to the clamping body and can rotate around its own axis; the clamping block should be connected to the end of the rotating part away from the clamping body so that it swings around the axis with the rotating part. Here, the swinging refers to the clamping block swinging clockwise or counterclockwise around the axis of the rotating part at a preset angle; the reset member is used to maintain the clamping block in the initial position. In this way, when the clamping block is clamped on the outer edge of the target object, the relative rotation or swinging between the clamping block and the clamping body can be caused by the reset member and the rotating part to adapt to the requirement that the connection position between the target object and the clamping assembly changes instantaneously during the flipping process.

[0018] In some embodiments, the placement platform includes a main placement platform and two secondary placement platforms respectively disposed on the main placement platform. The clamping blocks and the clamping bodies are slidably connected to the secondary placement platforms, and the two clamping blocks can slide towards each other or away from each other along a second direction.

[0019] Understandably, the main placement platform is fixed in place, while the two secondary placement platforms move relative to the main placement platform in the second direction, either facing each other or moving away from each other. In this way, the spacing between the clamping blocks of the two clamping components is adjusted to accommodate target objects of different widths.

[0020] In some embodiments, the clamping assembly further includes a clamping platform, the clamping body is fixed to the clamping platform, and the clamping platform is slidably connected to the placement sub-platform.

[0021] Understandably, the clamping body and the clamping block are slidably connected to the placement platform through the clamping platform. As the clamping platform slides relative to the placement sub-platform, the clamping body and the clamping block can also slide relative to the placement sub-platform in the second direction.

[0022] In some embodiments, the flipping part further includes a first limiting component, which is disposed on a corresponding placement sub-platform and is used to limit the range of movement of the clamping block in opposite directions in a second direction.

[0023] Understandably, the first limiting component can be a partition, barrier, or telescopic component, etc., used to limit the range of movement of the clamping block in the second direction, so as to limit the maximum width of the test target object.

[0024] In some embodiments, the clamping block has a first end, a second end disposed opposite to the first end, and a third end connecting the first end and the second end. The first end clamps the target object, the second end is connected to the rotating part, and the third end is connected to the reset member.

[0025] Understandably, the first end is the end of the clamping block facing the target object, used for direct connection with the outer edge of the target object; the second end is the end connected to the rotating part, and is arranged opposite to the first end in the second direction; the third end is the end used for connection with the reset member. For example, a mounting hole or mounting post can be provided at the third end to set the reset member on the corresponding mounting hole or mounting post.

[0026] In some embodiments, the first end includes a wedge-shaped portion, a transition portion, and a support portion spaced apart from the wedge-shaped portion, wherein the wedge-shaped portion, the transition portion, and the support portion enclose a notch for engaging with the outer edge of the target object.

[0027] Understandably, the wedge-shaped portion is used for mounting the target object. Generally, the target object enters the notch from the wedge-shaped portion. The transition portion has a corresponding accommodating space to accommodate the outer edge of the target object. For example, a straight transition portion adapts to the straight outer edge of the target object, or an arc-shaped transition portion adapts to the arc-shaped outer edge of the target object. The support portion is used to support the target object to ensure the connection stability of the target object during the testing process.

[0028] In some embodiments, the flipping platform includes a flipping main platform and a first flipping sub-platform slidably connected to the flipping main platform. The first flipping sub-platform slides relative to the flipping main platform along a first direction, and the placement platform is disposed on the first flipping sub-platform.

[0029] Understandably, the first flipping sub-platform slides relative to the flipping main platform in the first direction to accommodate the dynamic change in the rotation center of the target object located on the placement platform during the flipping process.

[0030] In some embodiments, the flipping platform further includes a second flipping sub-platform, which is slidably connected to the first flipping sub-platform. The second flipping sub-platform slides relative to the first flipping sub-platform along a second direction, and the placement platform is placed on the first flipping sub-platform via the second flipping sub-platform.

[0031] Understandably, the second flipping sub-platform slides relative to the first flipping sub-platform in the second direction, thereby satisfying the target object's movement margin in the extension direction along its own rotation center axis, further improving the adaptability of the target object during the flipping process.

[0032] In some embodiments, the excitation unit further includes an excitation platform connected to the flipping platform and a slide rail structure disposed on the excitation platform. The excitation active part is slidably connected to the slide rail structure and is limited to the slide rail structure. The force acquisition part is disposed on the excitation platform and the excitation active part is directed toward or away from the target object to trigger the force acquisition part.

[0033] Understandably, the excitation platform is connected to the flipping platform to achieve synchronous flipping of the excitation unit and the flipping unit. Here, the slide rail structure is used to guide the excitation moving unit. Driven by the excitation fixing unit, the excitation moving unit moves towards or away from the target object. At the same time, during the sliding process, the force acquisition unit synchronously acquires the displacement of the excitation moving unit relative to the slide rail structure, that is, the first displacement.

[0034] In some embodiments, the triggering part has a head end that abuts against the target object and a protrusion that slides synchronously with the head end, the protrusion being used to trigger the force acquisition part.

[0035] Understandably, the head end is used to abut against the outer edge of the target object. The structural form of the head end is not limited; for example, it can be a snap-fit ​​structure, engaging with the outer edge of the target object, or it can be a protruding post, abutting against the outer edge of the target object. The protruding part is the portion that extends outward from the actuating part, and as the actuating part moves, it ultimately triggers the collection part.

[0036] In some embodiments, the measuring unit includes a measuring power unit and a displacement sensor located at the output end of the measuring power unit, the displacement sensor being used to abut the outer edge of the target object.

[0037] Understandably, the measuring power unit includes, but is not limited to, telescopic cylinders, lead screw structures, etc., used to provide the force that the displacement sensor exerts against the outer edge of the target object.

[0038] In some embodiments, the measuring unit further includes a second limiting component, which is used to limit the displacement sensor from making contact with the target object.

[0039] Understandably, the second limiting component is used to limit the contact range between the displacement sensor and the target object, and can also actively reset the displacement sensor. Here, the second limiting component includes, but is not limited to, a pushing member, a telescopic member, and a lead screw mechanism.

[0040] In some embodiments, the dynamic misalignment detection device further includes an auxiliary platform, the height of which is flush with the height of the placement platform, and the auxiliary platform is used to fix the portion of the target object that has not been flipped.

[0041] Understandably, the auxiliary platform is used to limit the portion of the target object that has not been flipped. Here, the limiting method can be to directly limit and fix the outer edge of the target object using mounting slots, mounting holes, etc.

[0042] Secondly, this application provides a detection method for a dynamic misalignment detection device, comprising the following steps:

[0043] Install the target object and fix it on the placement platform of the flipping part, so as to fix it to the outer edge of the target object by the clamping component;

[0044] The target object is flipped at a preset flipping rate, and the control unit controls the flipping power unit of the flipping unit to set the corresponding flipping rate.

[0045] The target object is brought into contact with the preset excitation force. The control unit controls the excitation fixing part of the excitation part to set the corresponding excitation force, and the force acquisition unit simultaneously acquires the magnitude of the excitation force implemented by the excitation moving part.

[0046] Perform a forward flip on the target object and record the first displacement sequence of the target object after the flip;

[0047] The target object is reverse-flipped, and the second displacement sequence of the target object after flipping is recorded. The difference between the first displacement sequence and the second displacement sequence is the dynamic virtual value of the current target object.

[0048] The technical solutions described in this application have at least the following technical effects or advantages:

[0049] The detection method of the dynamic false position detection device provided in this application embodiment can dynamically monitor the magnitude of the excitation force applied to the target object of the excitation activity unit through the excitation fixing part and the force acquisition part, so as to realize the dynamic adjustment of the excitation force during the flipping process of the target object, thus obtaining a more accurate false position value.

[0050] In some embodiments, the detection method further includes:

[0051] As a safety measure, if the rotation rate of the target object exceeds a preset value, the rotation will stop; and / or, if the excitation force applied to the target object exceeds a preset value, the excitation force will stop and the detection will end.

[0052] Understandably, safety measures are designed to prevent damage to the target object during the flipping process. For example, a preset flipping rate is set, and if the flipping rate exceeds the preset value, the flipping of the target object is stopped; or, a preset excitation force is set, and if the excitation force exceeds the preset value, the flipping of the target object is stopped.

[0079] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0080] Foldable devices, such as foldable phones and foldable platforms, incorporate hinge structures. During folding and rotation, these hinges exhibit a certain degree of "play-off," meaning that the interconnected structures within the hinge undergo relative positional changes as the device folds. This play-off in the hinge is crucial for enabling the device to fold.

[0081] However, current misalignment detection devices have low accuracy, leading to frequent issues such as poor flattening, jamming, and misalignment in foldable terminal products. The main reason is that current misalignment detection devices are ill-suited to the detection requirements of the constantly changing dynamic rotation center of foldable terminal products during the flipping process.

[0082] In view of this, this application provides a dynamic misalignment detection device. In the flipping section, the placement platform and the flipping platform can slide relative to each other along a first direction. When the target object is placed on the placement platform, the dynamic rotation center can be adapted by the relative sliding between the placement platform and the flipping platform. At the same time, the clamping component also adopts a movable connection to fix the target object, that is, the clamping block directly connected to the target object and the clamping body can rotate relative to each other to adapt to the problem of inaccurate misalignment value caused by the fixed connection position during the flipping process of the target object.

[0083] The target objects involved in the embodiments of this application may include foldable terminal devices, such as foldable mobile phones, foldable tablets, foldable watches, etc., and may also be folding structures with hinges, etc.

[0084] This application does not impose any special limitations on the specific form of the target object described above. For ease of explanation and understanding, the following description uses a foldable mobile phone as an example.

[0085] When foldable phones are tested for flipping and rotating, the two displays are folded or unfolded about the hinge. Therefore, during testing, one display needs to be fixed, while the other display is folded or unfolded about the hinge as the center of rotation.

[0086] Firstly, please refer to Figures 1 to 5 , Figure 7 This application provides a dynamic false position detection device 100, including a flipping part 10, an excitation part 20, a measuring part 30 and a control part 40.

[0087] The flipping part 10 is used to flip the target object. Specifically, the folded part of the target object is fixed to the flipping part 10, and the object is folded or unfolded relative to another part under the action of the flipping part 10.

[0088] The excitation unit 20 is used to apply a corresponding excitation force to the target object during the flipping process, so as to achieve the flipping of the target object within a certain range of virtual values. Specifically, the excitation force applied to the target object should fluctuate within a certain range during the flipping process.

[0089] The measuring unit 30 is used to measure the displacement change of the target object during the flipping process; for example, it can measure the displacement change of the outer edge of the target object during the opening and closing process from 0° to 180° and from 180° to 0°.

[0090] Furthermore, the control unit 40 controls the flipping unit 10, the excitation unit 20, and the measuring unit 30 to work together.

[0091] Specifically, the flipping unit 10 includes a flipping power unit 11, a flipping platform 12, a placement platform 13, and a clamping assembly 14. The flipping power unit 11 provides the power required to flip the target object; for example, it can be a motor or other mechanism capable of outputting torque. Both the flipping platform 12 and the placement platform 13 are used to place the target object. Specifically, the placement platform 13 is stacked on top of the flipping platform 12, and the target object is placed on the placement platform 13. The flipping platform 12 folds and rotates around the centerline of the output end of the flipping power unit 11, while the placement platform 13 slides relative to the flipping platform 12 along a first direction X, which is perpendicular to the extension direction of the target object's flipping axis. Here, the flipping platform 12 and the placement platform 13 rotate synchronously under the drive of the flipping power unit 11 to flip the target object. Simultaneously, the placement platform 13 and the flipping platform 12 can slide relative to each other. Specifically, the placement platform 13 slides relative to the flipping platform 12 along the first direction X to accommodate the dynamic change of the target object's flipping center during the flipping process. The clamping assembly 14 includes a clamping body 141 disposed on the placement platform 13 and a clamping block 143 rotatably connected to the clamping body 141. The clamping block 143 is used to clamp the outer edge of the target object. The clamping block 143 can rotate relative to the clamping body 141 within a preset angle about the second direction Y. Here, the first direction X is perpendicular to the second direction Y. The clamping block 143 and the clamping body 141 are rotatably connected, thereby satisfying the dynamic clamping of the clamping block 143 and the target object. That is, the clamping position of the clamping block 143 on the target object can change accordingly according to the flipping process. Specifically, the clamping block 143 can swing synchronously with the target object during the flipping process. Thus, when the target object is flipped to measure its displacement, the flipping part 10 can adapt to the constantly changing flipping rotation center of the target object and perform dynamic clamping of the target object to improve the accuracy of the measurement process.

[0092] The excitation unit 20 rotates synchronously with the flipping platform 12. Specifically, the excitation unit 20 includes an excitation power unit 21 and a force acquisition unit 22. The excitation power unit 21 includes an excitation moving part 211 and an excitation fixing part 212 for driving the excitation moving part 211 toward the target object. Here, the excitation fixing part 212 provides the excitation moving part 211 with the power to abut against the target object, so that the excitation moving part 211 can abut against the target object and maintain within a certain range. At the same time, the force acquisition unit 22 acquires the first displacement of the excitation moving part 211. The force acquisition unit 22 is electrically connected to the excitation fixing part 212. At the same time, the acquired first displacement is also fed back to the excitation fixing part 212 to form a closed-loop control.

[0093] The measuring unit 30 is used to contact the target object to measure the second displacement of the target object during the folding and rotating process.

[0094] Here, the measuring unit 30 should be a sensor such as a displacement sensor or a force sensor. The measuring unit 30 is used to measure the second displacement of the target object during the folding and rotating process, and the difference between the second displacements after two folding and rotating processes can be used to calculate whether the corresponding false displacement value meets the requirements.

[0095] The control unit 40 is electrically connected in sequence to the flipping power unit 11, the excitation power unit 21, the force acquisition unit 22, and the measurement unit 30.

[0096] Here, the control unit 40 can be any type of controller, used to control the flipping angle, speed and excitation force of the target object, and also to realize the coordinated work between the various units.

[0097] In the specific testing process, the part of the target object to be rotated is placed on the placement platform 13 and fixed by the clamping block 143. The control unit 40 controls the flipping power unit 11 to drive the flipping platform 12 to rotate at a preset flipping rate, that is, the rotating part of the target object on the placement platform 13 is flipped towards the non-rotating part. At the same time, the control unit 40 controls the activation fixing unit 212 to apply force to the activation moving unit 211 to push the activation moving unit 211 against the outer edge of the part of the target object to be rotated, and the force acquisition unit 22 acquires the current activation force of the activation moving unit 211 and feeds the acquired data back to the control unit 40 so that the control unit 40 can monitor the output efficiency of the activation fixing unit 212 in real time. The control unit 40 can control the measurement unit 30 to measure the displacement change of the outer edge of the target object during the flipping process.

[0098] The dynamic misalignment detection device 100 provided in this application embodiment operates as follows: the flipping unit 10 drives the target object to fold and rotate. During the folding and rotation, the excitation unit 20 applies an excitation force to the target object, and the measuring unit 30 measures the displacement of the target object during the folding and rotation. Furthermore, the misalignment value of the target object is obtained by comparing the displacement of forward and reverse folding. The control unit 40 controls the coordinated operation between the various units. Specifically, the target object is mounted on the placement platform 13 and folds and rotates synchronously with the flipping platform 12. The placement platform 13 can slide relative to the flipping platform 12 in the first direction X to accommodate the dynamic change of the target object's rotation center during the folding and rotation. Simultaneously, the clamping block 143 of the clamping unit can rotate within a preset angle relative to the clamping body 141 around the second direction Y. That is, the clamping assembly 14 and the target object are movably connected, thus eliminating the torsional force of the clamping assembly 14 on the target object and reducing the possibility of damage to the target object. Thus, the dynamic misalignment detection device 100 provided in this application can adapt to the constantly changing rotation center of the target object during the folding and rotation process, resulting in smaller detection errors and higher accuracy.

[0099] Please refer to Figure 4 and Figure 5 In some embodiments, the clamping assembly 14 includes a clamping body 141, a rotating part 142 rotatably connected to the clamping body 141, a clamping block 143 connected to the rotating part 142, and a reset member 144 whose two ends are respectively connected to the clamping body 141 and the clamping block 143. The number of reset members 144 is even, and each reset member 144 is symmetrically arranged in pairs with the rotation center axis of the rotating part 142 as the center of symmetry.

[0100] Understandably, the clamping body 141 is fixed; the rotating part 142 is rotatably connected to the clamping body 141 and is capable of rotating around its own axis; the clamping block 143 should be connected to the end of the rotating part 142 away from the clamping body 141, so as to swing around the axis with the rotating part 142. Here, the swing refers to the clamping block 143 swinging clockwise or counterclockwise around the axis of rotation of the rotating part 142 at a preset angle; the reset member 144 is used to maintain the clamping block 143 in the initial position. In this way, when the clamping block 143 is clamped on the outer edge of the target object, the relative rotation or swing between the clamping block 143 and the clamping body 141 can be caused by the reset member 144 and the rotating part 142, so as to adapt to the requirement that the connection position between the target object and the clamping assembly 14 changes instantaneously during the flipping process.

[0101] For example, the reset member 144 is a spring, and there are two reset members 144. The two reset members 144 are symmetrically arranged on the clamping block 143 with the rotation center axis of the rotating part 142 as the center of symmetry. Furthermore, it is ensured that the two reset members 144 have the same size specifications. In the initial state, the clamping block 143 is in a state of force balance. Once it comes into contact with the outer edge of the target object and deflects, the corresponding reset member 144 can spring back to reset, so that the clamping block 143 can return to the state of force balance.

[0102] Please refer to the figure. In some embodiments, the placement platform 13 includes a main placement platform 131 and two secondary placement platforms 132 respectively disposed on the main placement platform 131. The clamping block 143 and the clamping body 141 are slidably connected to the secondary placement platforms 132. Furthermore, the two clamping blocks 143 can slide towards each other or away from each other along the second direction Y.

[0103] Understandably, the main platform 131 is fixed, while the two secondary platforms 132 move relative to the main platform 131 along the second direction Y, either facing each other or moving away from each other. In this way, the spacing between the clamping blocks 143 of the two clamping components 14 is adjusted to accommodate target objects of different widths.

[0104] Please refer to Figure 4In some embodiments, the clamping assembly 14 further includes a clamping platform 145, the clamping body 141 is fixed on the clamping platform 145, and the clamping platform 145 is slidably connected to the placement sub-platform 132.

[0105] It is understood that the clamping body 141 and the clamping block 143 are slidably connected to the placement platform 13 via the clamping platform 145. As the clamping platform slides relative to the placement sub-platform 132, the clamping body 141 and the clamping block 143 can also slide relative to the placement sub-platform 132 in the second direction Y.

[0106] For example, the clamping platform 145 is slidably connected to the placement sub-platform 132 via a slider and a slide rail.

[0107] Please refer to Figure 4 In some embodiments, the flipping part 10 further includes a first limiting component 15, which is disposed on the corresponding placement sub-platform 132. The first limiting component 15 is used to limit the range of movement of the clamping block 143 in the second direction Y.

[0108] Understandably, the first limiting component 15 may be a partition, barrier, or telescopic component, etc., used to limit the range of movement of the clamping block 143 in the second direction Y, so as to limit the maximum width of the test target object.

[0109] For example, the first limiting component 15 includes a limiting power unit and a limiting push rod disposed on the limiting power unit. Under the action of the limiting power unit, the limiting push rod pushes the clamping block 143 to adapt to target objects of different length specifications.

[0110] Please refer to Figure 6 In some embodiments, the clamping block 143 has a first end 143a, a second end 143b disposed opposite to the first end 143a, and a third end 143c connecting the first end 143a and the second end 143b. The first end 143a clamps the target object, the second end 143b is connected to the rotating part 142, and the third end 143c is connected to the reset member 144.

[0111] Understandably, the first end 143a is the end of the clamping block 143 facing the target object, used for direct connection with the outer edge of the target object, the second end 143b is the end connected to the rotating part 142, and is arranged opposite to the first end 143a in the second direction Y, and the third end 143c is the end used for connection with the reset member 144. For example, a mounting hole or mounting post can be provided in the third end 143c to set the reset member 144 on the corresponding mounting hole or mounting post.

[0112] Please refer to Figure 6In some embodiments, the first end portion 143a includes a wedge-shaped portion 143a1, a transition portion 143a2, and a support portion 143a3 spaced apart from the wedge-shaped portion 143a1. The wedge-shaped portion 143a1, the transition portion 143a2, and the support portion 143a3 enclose a notch for engaging with the outer edge of the target object.

[0113] Understandably, the wedge-shaped portion 143a1 is used for mounting the target object. Generally, the target object enters the notch through the wedge-shaped portion 143a1. The transition portion 143a2 has a corresponding accommodating space for accommodating the outer edge of the target object. For example, the straight transition portion 143a2 is adapted to the straight outer edge of the target object, or the arc-shaped transition portion 143a2 is adapted to the arc-shaped outer edge of the target object. The support portion 143a3 is used to support the target object to ensure the connection stability of the target object during the testing process.

[0114] For example, the geometric center of the notch coincides with the midpoint of the line connecting the two reset members 144, or the geometric center of the notch coincides with or is parallel to the rotation center of the rotating part 142. In this way, the force balance of the clamping block 143 during the clamping process can be improved.

[0115] Please refer to the figure. In some embodiments, the flipping platform 12 includes a flipping main platform 121 and a first flipping sub-platform 122 slidably connected to the flipping main platform 121. The first flipping sub-platform 122 slides relative to the flipping main platform 121 along a first direction X, and the placement platform 13 is disposed on the first flipping sub-platform 122.

[0116] Understandably, the first flipping sub-platform 122 slides relative to the flipping main platform 121 in the first direction X to accommodate the dynamic change of the rotation center of the target object located on the placement platform 13 during the flipping process.

[0117] Please refer to Figure 3 In some embodiments, the flipping platform 12 further includes a second flipping sub-platform 123, which is slidably connected to the first flipping sub-platform 122. The second flipping sub-platform 123 slides relative to the second flipping sub-platform 123 along the second direction Y, and the placement platform 13 is placed on the first flipping sub-platform 122 through the second flipping sub-platform 123.

[0118] Understandably, the second flipping sub-platform 123 slides relative to the first flipping sub-platform 122 in the second direction Y, thereby satisfying the target object's movement margin along the extension direction of its own rotation center axis, further improving the adaptability of the target object during the flipping process.

[0119] Please refer to Figure 8 and Figure 9In some embodiments, the excitation unit 20 further includes an excitation platform 23 connected to the flipping platform 12 and a slide rail structure 24 disposed on the excitation platform 23. The excitation active unit 211 is slidably connected to the slide rail structure 24 and is limited to the slide rail structure. The force acquisition unit 22 is disposed on the excitation platform 23. The excitation active unit 211 is directed toward or away from the target object to trigger the force acquisition unit 22.

[0120] Understandably, the excitation platform 23 is connected to the flipping platform 12 to achieve synchronous flipping of the excitation unit 20 and the flipping unit 10. Here, the slide rail structure 24 is used to guide the excitation moving unit 211. Driven by the excitation fixing unit 212, the excitation moving unit 211 moves towards or away from the target object. At the same time, during the sliding process, the force acquisition unit 22 synchronously acquires the displacement of the excitation moving unit 211 relative to the slide rail structure 24, that is, the first displacement.

[0121] Please refer to Figure 9 In some embodiments, the triggering part 211 has a head end 211a that abuts against the target object, and an extension 211b that slides synchronously with the head end 211a, the extension 211b being used to trigger the force acquisition part 22.

[0122] Understandably, the head end portion 211a is used to abut against the outer edge of the target object. The structural form of the head end portion 211a is not limited. For example, the head end portion 211a can be a snap-fit ​​structure, which snaps onto the outer edge of the target object; or, the head end portion 211a can be a protrusion, which abuts against the outer edge of the target object. The protruding portion 211b is the part that extends outward from the actuating part 211, and as the actuating part 211 moves, it ultimately triggers the force-collecting part 22.

[0123] Please refer to Figure 8 and Figure 9 In some embodiments, the measuring unit 30 includes a measuring power unit 31 and a displacement sensor 32 located at the output end of the measuring power unit 31. The displacement sensor 32 is used to abut the outer edge of the target object.

[0124] Understandably, the measuring power unit 31 includes, but is not limited to, a telescopic cylinder, a lead screw structure, etc., used to provide the force that the displacement sensor 32 applies to the outer edge of the target object.

[0125] Please refer to Figure 9 In some embodiments, the measuring unit 30 further includes a second limiting component 33, which is used to limit the displacement sensor 32 from making contact with the target object.

[0126] Understandably, the second limiting component 33 is used to limit the contact range of the displacement sensor 32 with the target object, and can also actively reset the displacement sensor 32. Here, the second limiting component 33 includes, but is not limited to, a pushing member, a telescopic member, and a lead screw mechanism.

[0127] Please refer to Figure 1 In some embodiments, the dynamic misalignment detection device 100 further includes an auxiliary platform 50, the height of which is flush with the height of the placement platform 13, and the auxiliary platform 50 is used to fix the part of the target object that has not been flipped.

[0128] Understandably, the auxiliary platform 50 is used to limit the portion of the target object that has not been flipped. Here, the limiting method can be to directly limit and fix the outer edge of the target object using mounting slots, mounting holes, etc.

[0129] Secondly, please refer to Figure 10 This application provides a detection method for a dynamic false position detection device 100, comprising the following steps:

[0130] S001. Install the target object and fix it on the placement platform 13 of the flipping part 10 so as to fix it to the outer edge of the target object by the clamping assembly 14.

[0131] S002. The target object is flipped at a preset flipping rate. The control unit 40 controls the flipping power unit 11 of the flipping unit 10 to set the corresponding flipping rate.

[0132] S003. The target object is brought into contact with the target object according to the preset excitation force. The control unit 40 controls the excitation fixing part 212 of the excitation part 20 to set the corresponding excitation force, and the force acquisition unit 22 synchronously acquires the magnitude of the excitation force implemented by the excitation moving part 211.

[0133] Here, the control unit 40 controls the stimulation force applied to the target object by the stimulation fixing unit 212. At the same time, the force acquisition unit 22 acquires the magnitude of the stimulation force applied to the target object by the stimulation activity unit 211 and feeds it back to the control unit 40, forming a control closed loop. In this way, the control unit 40 can dynamically adjust the magnitude of the stimulation force applied to the target object within a certain range.

[0134] S004. Perform a forward flip on the target object and record the first displacement sequence of the target object after the flip.

[0135] S005. Perform reverse flipping on the target object and record the second displacement sequence of the target object after flipping. The difference between the first displacement sequence and the second displacement sequence is the dynamic virtual value of the current target object.

[0136] The detection method of the dynamic vacancy detection device 100 provided in this application embodiment can dynamically monitor the magnitude of the excitation force applied to the target object by the excitation moving part 211 through the excitation fixing part 212 and the force acquisition part 22, so as to realize the dynamic adjustment of the excitation force during the flipping process of the target object. In this way, a more accurate vacancy value can be obtained.

[0137] Please refer to Figure 11 In some embodiments, the detection method further includes:

[0138] S006. Safety measures: If the rotation rate of the target object exceeds a preset value, the rotation will stop; and / or, if the excitation force applied to the target object exceeds a preset value, the excitation force will stop and the detection will end.

[0139] Understandably, safety measures are designed to prevent damage to the target object during the flipping process. For example, a preset flipping rate is set, and if the flipping rate exceeds the preset value, the flipping of the target object is stopped; or, a preset excitation force is set, and if the excitation force exceeds the preset value, the flipping of the target object is stopped.

[0140] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
