Embodiment 1

[0040] Example 1, such as Figure 1 to Figure 4 As shown, the tire laser speckle inspection machine mainly has a frame 1, a support frame 2, a lifting device, a rotating device, a horizontal reciprocating device and a laser detection device. in,

[0041] The support frame 2 is connected to one side of the frame 1, and the support frame 2 supports the frame 1 from one side, which is beneficial to improve the reinforcement and stability of the laser detection device during rotation, so as to avoid the shaking of the laser detection head.

[0042] The lifting device is arranged in 2 groups, which are installed on the frame 1 respectively, and the rotating device is installed on the lifting beam 30 of the lifting device.

[0043] Each group of lifting devices also includes a lifting motor 31, a driving pulley 32, a lifting shaft 33, a lifting synchronous belt 34, and a driven pulley 35.

[0044] The lifting motor 31 is connected with the lifting shaft 33, the lifting shaft 33 is...

Abstract

The invention relates to a tyre laser speckle inspection machine and an inspection method thereof. A rotating drive part is added in a laser inspection device so as to control laser inspection heads to accurately rotate along the axial directions of locating shafts and to be regulated and located. The omnibearing photo scanning of the tread and the sidewall of a tyre is realized at one station by adopting a laser speckle inspection machine, and equipment has relatively simple overall structure and higher inspection efficiency and can be suitable for inspecting tyres with various types and specifications and sizes. The inspection machine mainly comprises a stand, a support frame, a lifting device, a rotating device, a horizontal reciprocate mobile device and a laser inspection device, wherein the laser inspection device comprises two mounting racks symmetrically connected below fixing plates of the horizontal reciprocate mobile device, and the end part of each mounting rack is provided with one laser inspection head. Each laser inspection head rotates within the range smaller than 90 degrees by the rotating drive part connected with the laser inspection head along the locating shafts arranged at the end parts of the mounting racks.

Description

technical field [0001] The invention relates to a laser speckle inspection machine and an inspection method applied to non-destructive inspection of tires, in particular controlling a laser detection head to rotate an angle to realize photo scanning of tire sidewalls, belonging to the field of rubber machinery. Background technique [0002] In the manufacturing process of motor vehicle tires, in order to improve the production quality and ensure the use requirements of its safe operation, a series of online inspection items are usually carried out. For example, the principle of laser speckle imaging inspection is used to conduct non-destructive inspection on the inner layer of the tire by emitting laser rays to the tire surface, and the signal of varying strength generated by the laser passing through the tire is fed back to the CCD camera for imaging to verify whether the tire is inside. If there are performance defects such as air bubbles, the tires will be identified and ...
