[0033] Example
[0034] In order to address a series of shortcomings in the existing technology of manually testing and adjusting the torque of laptop hinges;
[0035] refer to Figure 1 As shown, this application provides the following solution: an intelligent torsion testing machine, including a testing platform 10, a torsion detection mechanism 20, a swing torsion mechanism 30, and a torsion adjustment mechanism 40;
[0036] The torque testing mechanism 20 includes a torque testing unit 21 mounted on the testing machine 10 and a fixing fixture 22 connected to the torque testing unit 21. In actual operation, the operator must fix a bracket of the laptop hinge to be tested in the fixing fixture 22.
[0037] The swinging and twisting mechanism 30 includes a rotary drive unit 31 mounted on the test platform 10, a telescopic drive unit 32 connected to the rotary drive unit 31 on one side of the torque detection unit 21, an elastic sliding unit 33 connected to the telescopic drive assembly, and a clamping fixture 34 rotatably mounted on the elastic sliding unit 33. When the laptop hinge to be tested is fixed in the fixing fixture 22, the telescopic drive assembly drives the elastic sliding unit 33 to extend and retract until the other bracket of the laptop hinge is clamped by the clamping fixture 34. When the above action is completed, the rotary drive unit 31 will drive the telescopic drive unit 32, the elastic sliding unit 33 and the clamping fixture 34 to rotate. At the same time, the laptop hinge bracket clamped by the clamping fixture 34 will twist, and the torque detection unit 21 will detect the torque change in real time.
[0038] The torque adjustment mechanism 40 includes a first mounting bracket 41 vertically mounted on the test platform 10, a lifting drive unit 42 mounted on the first mounting bracket 41, and a nut tension adjustment unit 43 connected to the lifting drive unit 42. Based on the torque value detected by the torque detection unit 21, if the torque value is within the qualified range, no torque adjustment action is performed. If the torque value is too large or too small, the lifting drive unit 42 will drive the nut tension adjustment unit 43 to descend, and adjust the tension of the nut on the laptop hinge through the nut tension adjustment unit 43 to achieve torque adjustment.
[0039] refer to Figure 5 As shown, in addition to the above structure, in order to realize the real-time continuous torque test value of each laptop hinge and facilitate the upload to the enterprise's MES system for later traceability, this application also includes a torque photo uploading mechanism 50. The torque photo uploading mechanism 50 includes a second mounting bracket 51 located on one side of the test machine 10, a vision camera 52 located on the second mounting bracket 51 and facing the torque detection unit 21, and a ring light source 53 located below the vision camera 52 on the second mounting bracket 51. During the torque test of the laptop hinge, the vision camera 52 of this application records and uploads the torque value displayed on the torque detection unit 21 in real time to the enterprise's MES system.
[0040] refer to Figure 2As shown, in one specific embodiment, the torque detection unit 21 of this application includes a raised block 211 arranged side by side on the test platform 10, a test box 212 arranged above the raised block 211, a torque detection sensor 213 arranged above the test box 212, and a digital display module 214 arranged on the test box 212 facing the vision camera 52 and electrically connected to the torque detection sensor 213. The fixing fixture 22 includes a fixing support 221 connected above the torque detection sensor 213, a fixture block arranged above the fixing support 221, and a contour slot 222 opened above the fixture block. In actual use, the operator inserts one bracket of the laptop hinge into the contour slot 222. When the swinging and twisting mechanism 30 drives the other bracket of the other laptop hinge to rotate, the torque detection sensor 213 will detect the corresponding torque value and send it to the digital display module 214 for display.
[0041] refer to Figure 3 As shown, in one embodiment, the rotary drive unit 31 of this application includes a bearing seat 312 disposed above the test machine 10, a first reduction motor 311 disposed below the test machine 10 with its drive shaft passing through the test machine 10 to the bearing seat 312, a torsion plate 313 rotatably connected above the bearing seat 312, and a frame 314 disposed above the torsion plate 313 away from the test box 212, an elastic sliding unit 33 disposed above the telescopic drive unit 32, a first base plate 331 disposed above the first base plate 331, a linear guide rail 332 disposed above the first base plate 331, a sliding seat 333 slidably disposed above the linear guide rail 332, a blocking plate (not shown) disposed on the first base plate 331 near the test box 212, two support plates 334 respectively disposed on both sides of the telescopic drive unit 32, and a partition plate 334 respectively disposed on the two support plates 334. The spring 335 is not connected to the sliding seat 333. The clamping fixture 34 includes a second base plate 341 above the sliding seat 333, a bearing 342 inside the second base plate 341 and connected to the sliding seat 333 by a shaft 343, a clamping plate 344 on one side above the second base plate 341, and a slot 345 on the clamping plate 344. Based on this embodiment, the entire swing torsion mechanism 30 can be formed. The detailed operating principle is as follows: the telescopic drive unit 32 drives the first base plate 331 to extend until the other bracket of the laptop hinge extends into the slot 345. Then, the first reduction motor 311 is controlled to drive the torsion plate 313 to twist. During this process, the other bracket of the laptop hinge will twist and the sliding seat 333 can slide elastically on the linear guide rail 332.
[0042] Based on the above embodiments, the telescopic drive unit 32 of this application is an electric slide or a pneumatic slide mounted on the frame 314. In specific implementation, if other types of telescopic drive units 32 can replace the electric slide or pneumatic slide, those skilled in the art can make corresponding substitutions, and no further requirements are made here.

According to the detection result of the torque detection unit 21, the lifting drive unit 42 is controlled to drive the L-shaped support 431, the second geared motor 432, and the electric screwdriver 434 to descend until the nut of the laptop hinge is located in the electric screwdriver 434. After this action is completed, the tension of the nut can be adjusted by controlling the second geared motor 432 to drive the screwdriver bit to rotate forward or backward. In this way, the torque of the laptop hinge can be adjusted.
[0044] Based on the previous embodiment, the lifting drive unit 42 of this application is an electric slide or a pneumatic slide mounted on the first mounting bracket 41. In specific implementation, if other types of lifting drive units 42 can replace the electric slide or pneumatic slide, those skilled in the art can make corresponding substitutions, and no further requirements are made here.
