Abstract
The invention discloses a device for detecting defects at the inner part of a tire, comprising a low pressure chamber capable of holding the tire to be detected, a low pressure generating device capable of forming a low pressure environment in the low pressure chamber, a light source capable of emitting the incident light to the surface of the tire, an imaging objective lens matched with a reflecting light of the incident light, a beam splitter prism matched with the imaging objective lens and a charge coupled device (CCD) image sensor matched with the beam splitter prism. By adopting the device, the happening of traffic accident is reduced by detecting whether the inner part of the tire has defects.
Description
Technical field
The present invention relates to a kind of inside tires defects detection equipment.
Background technology
Because there is defective in tire, automobile is when running at high speed, and fault location is prone to shear strain takes place, and causes subduing Sheng Re and stress and concentrates, and makes defective constantly enlarge.At present, the traffic hazard that highway takes place, 2nd/3rd, because the initiation of wheel tyre defect, the wheel tyre defect that has occurs in the tread rubber place; What have occurs in the carcass, and occurs in the defective in the carcass, very easily cause blowing out, yet; Whether there is defective in the carcass, can not distinguishes, make the stealthy killer who has defective to become in the carcass to lead to traffic accident through naked eyes; Very harmful, so, demand occurring a kind of method or the generation of equipment that can detect the tire inherent vice urgently to cut down traffic accidents.
Summary of the invention
Problem to prior art exists the objective of the invention is to propose a kind of inside tires defects detection equipment, has realized whether having defective through detecting inside tires, with the generation that cuts down traffic accidents.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of inside tires defects detection equipment, comprise the low-pressure chamber that can hold tire to be detected, the low pressure generation equipment that can in said low-pressure chamber, form environment under low pressure, can to the light source of said surface of tyre emitting incident light, cooperate said reflection of incident light light image-forming objective lens, cooperate said image-forming objective lens Amici prism, cooperate the ccd image sensor of said Amici prism.
Also comprise the travel mechanism that said tire is moved in said vacuum chamber.
Also comprise the catoptron that cooperates said Amici prism.
Said catoptron and/or said catoptron band piezoelectric ceramics.
Said low pressure generation equipment is vacuum generating equipment.
Said light source is a laser instrument.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
In the present invention, at first tire is sent into low-pressure chamber, tire table wall each point is carried out IMAQ; Open low pressure generation equipment, make low-pressure chamber be in vacuum state, again tire table wall each point is carried out IMAQ; If there is defective in inside tires, under the inside and outside differential pressure effect, can make surface of tyre expansion point can occur; Promptly can find relatively to can be used as the difference that exists in the image and judge the foundation that whether has defective in the tire, and can judge the position of inherent vice.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1:
Wherein: 1, low-pressure chamber; 2, tire; 3, Amici prism; 4, catoptron; 5, catoptron; , ccd image sensor; 7, light source; 8, image-forming objective lens; 9, low pressure generation equipment.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment:
Propose a kind of inside tires defects detection equipment, comprise the low-pressure chamber 1 that can hold tire 2 to be detected, low pressure generation equipment 9 is vacuum generating equipment; Can in low-pressure chamber 1, make vacuum environment, through operation travel mechanism, tire 2 can move in low-pressure chamber 1; Light source 7 is a laser instrument, can launch laser as incident light to the surface local of tire 2, and incident illumination is mapped to after tire 2 surfaces; Laser as incident light reflects, and on its reflected light path, is provided with image-forming objective lens 8, and image-forming objective lens 8 cooperates with Amici prism 3; Image is passed to ccd image sensor 6; For reaching best light efficiency, catoptron 4,5 cooperates Amici prism 3, catoptron 4 and/or catoptron 5 band piezoelectric ceramics.
Practical implementation to embodiment 1 further describes as follows:
Among the embodiment 1, at first tire 2 is sent into low-pressure chamber 1, tire 2 table wall each points are carried out IMAQ; Open low pressure generation equipment 9, make low-pressure chamber 1 be in vacuum state, again tire 2 table wall each points are carried out IMAQ; If there is defective in tire 2 inside, under the inside and outside differential pressure effect, can make tire 2 surfaces expansion point can occur; Promptly can find relatively to can be used as the difference that exists in the image and judge whether tire 2 inside exist the foundation of defective, and can judge the position of inherent vice.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
