AI Technical Summary

Problems solved by technology

The reduction in triangulation angle also reduces the overall size of the equipment that must move rapidly around and within the tire and possibly simultaneously with other equipment moving in the space around the tire itself

Embodiment Construction

[0093] refer to Figure 5 , reference numeral 100 denotes a workstation for analyzing tires in a tire production line.

[0094] Preferably, the workstation comprises a support 120 (eg a fifth wheel) adapted to support a tire 101 arranged on a side wall and to rotate the tire about its axis of rotation 140 (preferably arranged vertically).

[0095] The workstation 100 comprises a device 1 for analyzing tires.

[0096] Preferably, the workstation comprises a mobile member 102 (shown only schematically) on which the device 1 is mounted for movement in space. Preferably, the moving member of the device is a robotic arm. Preferably, the mobile member is an anthropomorphic robotic arm. Preferably, the moving member is an anthropomorphic robotic arm having at least five axes. It should be noted that, advantageously, the device 1 is inserted into the tire from the top, rather than from the bottom via the support 120 .

[0097] The device 1 comprises a support frame 2 intended to ...

Abstract

Apparatus (1) for analyzing tires and related methods, said apparatus comprising: a support frame (2) and an acquisition system (11) for acquiring three-dimensional images of the tire surface, said acquisition system being mounted on said support frame and comprising: a matrix camera (12) having an optical axis (16) and a laser source (20) adapted to emit a linear beam having a propagation plane (21) and a propagation axis (23), wherein said optical axis is aligned with said An acute angle (24) formed between the propagation axes is greater than or equal to 5° and less than or equal to 25°.

Description

technical field [0001] The invention relates to a device for analyzing tires in a tire production line, in particular by acquiring an image of the tire surface and further processing the image, for example for checking possible Detect defects. Background technique [0002] "Tire" generally means a finished tire, ie a tire after the steps of building, molding and curing, but may also be a green tire after the steps of building and before the steps of molding and / or curing. [0003] Typically, a tire has a substantially toroidal configuration about its axis of rotation during operation, and has an axial midline plane orthogonal to the axis of rotation, which is generally a plane of geometric (substantial) symmetry (eg, neglecting any small asymmetry, such as tread pattern and / or internal structure). [0004] The outer or inner surface of the tire denotes, respectively, the surface which remains visible after coupling of the tire to its mounting rim and the surface which is n...
