Embodiment Construction
[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0043] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0044] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a torsion test device and a lens production line. The torsion test device comprises a machine base, a fixing base, a torsion test device, a torsion calibration device and a control device, and the fixing base is used for fixing a to-be-detected piece arranged on a test station; the torsion testing device comprises a torsion head which is used for applying torsion to a to-be-tested device; the torsion calibration device comprises a torsion acting part and a torsion measuring part, the torsion acting part is used for bearing torsion applied by the torsion head arranged at the calibration station, and the torsion measuring part is used for measuring the magnitude of the torsion borne by the torsion acting part; and the control device is used for controlling the torsion testing device to work. According to the technical scheme provided by the invention, the torsion testing device is used for testing the torsion of the to-be-detected piece, and the torsion calibration device is used for measuring and detecting the torsion of the torsion head of the torsion testing device, so that whether the torsion value output by the torsion head has deviation or not is detected; and the problem that an existing torsion testing mode is inaccurate in testing is solved.
Description
technical field [0001] The invention relates to the field of production equipment, in particular to torque testing equipment and lens production lines. Background technique [0002] The lens module in the VR glasses has the function of adapting to the vision of the human eye. In order to adapt to the degree of myopia of the human eye, it is necessary to adjust the focus of the folded optical path imaging in the VR glasses through the focusing part of the lens. In the process of refocusing, the focusing part needs to be twisted, and adjusting the torque value of the focusing part affects the human-computer interaction experience, so it is necessary to control the torque value of the focusing part after the lens is assembled. [0003] Existing production methods often use manual or semi-automatic methods to control the torque value of the lens focusing parts, which is not precise in the control of the torque value. In the process of testing the torque by using an automatic tor...
