Description

Technical Field

[0001] The utility model relates to the technical field of notebook hinge detection mechanisms, and specifically relates to a detection mechanism for notebook hinges. Background Art

[0002] Notebook hinge detection aims to verify the structural reliability, life compliance, and user experience consistency, ensuring that the hinge has no breakage, looseness, or torque attenuation during long-term opening and closing, while meeting requirements such as moderate damping, smooth opening and closing without abnormal noise, and guaranteeing product durability and user operation comfort. Among them, in addition to the most common rotation life test, it also includes multi-angle positioning tests, which are usually for models that support 360° flipping or stopping at any angle. It is necessary to verify the accuracy and stability of the hinge at each positioning point to prevent the screen from automatically drooping.

[0003] In the prior art, for the multi-angle positioning test of notebook hinges, it is usually carried out manually, that is, manually flipping the screen part to a specific detection angle, and then observing the angle change within a certain period of time. If there is no angle change, it means the test is qualified, otherwise it is a defective product. The above manual test method is relatively cumbersome, and there are large inevitable errors and misjudgments due to the subjectivity of the operator and the fineness of the operation, making it difficult to accurately detect the reliability and stability of the multi-angle positioning of the hinge. Therefore, in view of the above problems, a detection mechanism for notebook hinges is proposed. Content of the Utility Model

[0004] To solve the technical problem that the notebook hinge detection technology in the prior art has inevitable errors and misjudgments due to manual operation by the operator and is difficult to perform accurate detection, the utility model provides a detection mechanism for notebook hinges.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problems is as follows:

[0006] A detection mechanism for notebook hinges includes a base, on the upper end surface of which a centrally arranged mounting table is fixedly provided, and a test mold is installed on the mounting table; a guide frame group symmetrically installed on both sides of the mounting table; a telescopic clamping mechanism slidably arranged in the guide frame group and performing circular motion to clamp the upper part of the test mold and drive its upper part to flip; a rotation driving frame installed on the base to drive the telescopic clamping mechanism to reciprocate slidably in the guide frame group; and an industrial camera arranged on the side far from the rotation driving frame to collect the motion information of the telescopic clamping mechanism and the upper part of the test mold.

[0007] In one possible implementation, the test mold is used to simulate a laptop structure, which includes a main unit and a screen unit, wherein the main unit is fixedly mounted on a mounting platform and the main unit and the screen unit are rotatably connected via a laptop hinge to be tested.

[0008] In one possible implementation, the guide frame assembly includes two symmetrically arranged arc-shaped guide plates, each with an arc-shaped groove.

[0009] In one possible implementation, the telescopic clamping mechanism includes a mounting frame in which a cylinder is fixedly mounted. A rotating chuck is rotatably connected to the shaft end of the cylinder, and two rotating clamping rollers are mounted on the rotating chuck.

[0010] In one possible implementation, end plates are fixedly installed at both ends of the mounting frame, and slide cylinders that slide in slidable contact with corresponding arc-shaped slide grooves are fixedly provided on the outer end faces of the end plates.

[0011] In one possible implementation, the rotating drive frame includes a bearing seat fixedly mounted on a base, on which a rotating transmission link is mounted, and a drive unit disposed at the end of the base for driving the transmission link to rotate. Two sets of link groups are fixedly mounted on the transmission link, and their top ends are fixedly connected to the mounting frame.

[0012] In one possible implementation, the drive unit includes a speed reducer and a stepper motor, wherein the output end of the speed reducer is fixedly connected to a transmission link, and the input end of the speed reducer is fixedly connected to the shaft end of the stepper motor.

[0013] In one possible implementation, an initial angle scale corresponding to the slide cylinder is provided on the arc-shaped guide plate facing the industrial camera, and a mold scale corresponding to the top of the test mold screen is provided. A pointer pointing to the initial angle scale is fixedly provided on the corresponding slide cylinder.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] During testing, the rotating drive frame drives the telescopic clamping mechanism connected to it to slide along the guide frame to a specified angle, thereby causing the screen of the test mold held by the telescopic clamping mechanism to rotate to the specified angle. Subsequently, the telescopic clamping mechanism can retract inward to separate from the test mold. If there is a defect in the laptop hinge at this time, the screen of the test mold will deflect under the action of gravity. This deflection can be accurately captured by an industrial camera. Therefore, in the above solution, the initial rotation angle of the screen of the test mold can be controlled more accurately, and the deflection under the action of gravity can be accurately captured by an industrial camera. This allows for a more accurate evaluation of the performance of the laptop hinge and can significantly reduce the errors and misjudgments caused by manual operation. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 As shown, this embodiment provides a detection mechanism for a laptop hinge, including a base 1, on which a centrally located mounting platform 2 is fixedly disposed on its upper surface, and a test mold 3 is mounted on the mounting platform 2; a guide frame assembly 4, which is symmetrically mounted on both sides of the mounting platform 2; a telescopic clamping mechanism 5, which is slidably disposed in the guide frame assembly 4 and performs circumferential motion to clamp the upper part of the test mold 3 and drive its upper part to flip; a rotation drive frame 6, which is mounted on the base 1 and is used to drive the telescopic clamping mechanism 5 to reciprocate within the guide frame assembly 4; and an industrial camera 7, which is disposed on the side away from the rotation drive frame 6 and is used to collect motion information of the telescopic clamping mechanism 5 and the upper part of the test mold 3.

[0025] The test mold 3 is used to simulate the structure of a laptop, which includes a main unit and a screen unit. The main unit is fixedly mounted on the mounting platform 2, and the main unit and the screen unit are rotatably connected through the laptop hinge to be tested, so as to most realistically simulate the working condition of the laptop hinge in actual use.

[0026] Based on the above structural scheme, during testing, the screen of the test mold 3 is first clamped and fixed by the extension of the telescopic clamping mechanism 5. Then, the rotating drive frame 6 will work to drive the telescopic clamping mechanism 5, which is connected to it, to slide along the guide frame group 4 to a specified angle, thereby causing the screen of the test mold 3 clamped by the telescopic clamping mechanism 5 to flip to the specified angle. After the initial rotation angle is set, the telescopic clamping mechanism 5 can retract inward and separate from the test mold 3. At this time, if there is a defect in the laptop hinge, the screen of the test mold 3 will deflect under the action of gravity. This deflection can be accurately captured by the industrial camera 7. Therefore, in the above scheme, the initial rotation angle of the screen of the test mold 3 can be controlled more accurately, and the deflection under the action of gravity can be accurately captured by the industrial camera 7. This allows for a more accurate evaluation of the performance of the laptop hinge and can significantly reduce the errors and misjudgments caused by manual operation.

[0027] like Figure 2 - Figure 4 As shown, the guide frame assembly 4 includes two symmetrically arranged arc-shaped guide plates 41, with arc-shaped grooves 42 on the arc-shaped guide plates 41. In cooperation with this, the telescopic clamping mechanism 5 includes a mounting frame 51, with end plates 55 fixedly mounted at both ends. The outer end faces of the end plates 55 are fixedly provided with slide cylinders 56 that slide in contact with the corresponding arc-shaped grooves 42. Based on the above structural scheme, since the mounting frame 51 slides in contact with the arc-shaped grooves 42 through the slide cylinders 56 at both ends, it can constrain the entire mounting frame 51 to make circular motion during the movement, providing the necessary structural basis for the telescopic clamping mechanism 5 to drive the screen of the test mold 3 to flip.

[0028] like Figure 4 As shown, a cylinder 52 is fixedly installed inside the mounting frame 51. A rotating chuck 53 is rotatably connected to the shaft end of the cylinder 52. Two rotating clamping rollers 54 are installed on the rotating chuck 53. The two clamping rollers 54 can clamp the screen part of the test mold 3 between them, and thus can apply a pushing force to the screen part of the test mold 3 in two directions, causing it to flip to a designated position. The rotatable characteristic of the rotating chuck 53 can ensure that the direction of the line connecting the two clamping rollers 54 can change synchronously during the sliding process, so that it can always be perpendicular to the screen part of the test mold 3.

[0029] like Figure 2 - Figure 3As shown, the rotating drive frame 6 includes a bearing seat 61 fixedly mounted on the base 1, on which a rotating transmission link 62 is mounted. It also includes a drive unit 63 located at the end of the base 1, which is used to drive the transmission link 62 to rotate. Two sets of link groups 64 are fixedly mounted on the transmission link 62, and their top ends are fixedly connected to the mounting frame 51. The drive unit 63 includes a reducer 631 and a stepper motor 632. The output end of the reducer 631 is fixedly connected to the transmission link 62, and the input end of the reducer 631 is fixedly connected to the shaft end of the stepper motor 632.

[0030] Based on the above structural scheme, when it is necessary to adjust the rotation angle of the screen part of the test mold 3, the stepper motor 632 works to amplify the torque through the reducer 631, thereby driving the transmission link 62 to rotate. When the transmission link 62 rotates, it can drive the mounting frame 51 to slide in the arc-shaped slide groove 42 through the link group 64, thereby changing the rotation angle of the screen part of the test mold 3.

[0031] To improve the accuracy of data acquired by the industrial camera 7, such as Figure 5 As shown, the arc-shaped guide plate 41 facing the industrial camera 7 has a set of initial angle scales 72 corresponding to the slide cylinder 56 and a set of mold scales 73 corresponding to the top of the screen of the test mold 3. The corresponding slide cylinder 56 is fixedly provided with a pointer 71 pointing to the initial angle scales 72. In the above structural scheme, the initial angle scales 72 and the pointer 71 are used to indicate the position information of the slide cylinder 56, while the mold scales 73 are used to indicate the position information of the screen of the test mold 3. This can provide a comparison reference for the industrial camera 7, so as to facilitate whether the position information has changed before and after comparison.

[0032] The working principle and usage process of this utility model:

[0033] During testing, the screen of the test mold 3 is first clamped and fixed by the extension of the telescopic clamping mechanism 5. Then, the rotating drive frame 6 will work to drive the telescopic clamping mechanism 5, which is connected to it, to slide along the guide frame group 4 to a specified angle, thereby causing the screen of the test mold 3 clamped by the telescopic clamping mechanism 5 to flip to a specified angle. At this time, the industrial camera 7 records the position information for subsequent comparison.

[0034] After the initial angle is set, the telescopic clamping mechanism 5 can retract inward and separate from the test mold 3. If the laptop hinge is defective, the screen part of the test mold 3 will deflect under the action of gravity, and this deflection can be accurately captured by the industrial camera 7 for comparison.

[0035] Therefore, in the above solution, the initial flip angle of the screen of the test mold 3 can be controlled more accurately, and the deflection caused by gravity can be accurately captured by the industrial camera 7, so as to evaluate the performance of the laptop hinge more accurately and significantly reduce the errors and misjudgments caused by manual operation.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
