Description

Glass test method

The invention relates to a glass testing equipment, in particular to a glass testing method and glass testing equipment.

Existing glass test equipment is to be tested with long wavelength (for example: red light with a wavelength between 620nm ~ 750nm) projected on the glass (for example, the penetration rate of about 650nm is only 50%). And then the long-wavelength light reflected by the surface to be measured is received by a receiver. However, the existing glass test equipment can be used based on the principle that glass will block long-wavelength light, so the receiver will not receive the light reflected by the non-test surface of the glass.

Accordingly, the test objects applicable to the existing glass test equipment are already limited by their established structural design, and therefore it is difficult to apply them to the ever-changing test requirements. For example, when the existing glass testing equipment is used to detect a high transmittance glass (for example, the transmittance of 410nm ~ 810nm is at least 90%), the receiver will also receive the above The long-wavelength light reflected by the non-measured surface of the glass further affects the detection result.

Therefore, the inventor believes that the above-mentioned shortcomings can be improved, and with great concentration of research and the application of scientific principles, we finally propose an invention with reasonable design and effective improvement of the above-mentioned shortcomings.

The embodiment of the present invention provides a glass testing method and glass testing equipment, which It can effectively improve the possible defects of existing glass testing equipment.

The embodiment of the present invention discloses a glass testing method, which includes: a pre-step: providing at least one glass and a glass testing equipment; a placing step: placing at least one of the glasses on a glass stage of the glass testing equipment Wherein, a surface of at least one of the glass that is far from the glass stage is defined as a surface to be detected; an irradiation step: an ultraviolet emitter of the glass testing equipment is directed toward the detection The area emits an ultraviolet light, so that a part of the ultraviolet light irradiates the attachment on the surface to be detected and is reflected, and another part of the ultraviolet light is incident on the glass and dissipated in the glass; and A receiving step: a light receiver is used to receive part of the ultraviolet light reflected by the attachment.

The embodiment of the present invention also discloses a glass testing device for detecting attachments on a glass. The glass testing device includes: a glass stage including a bearing surface, and the bearing surface is defined to bear the A detection area of the glass; an ultraviolet emitter located above the bearing surface, and the ultraviolet emitter can emit an ultraviolet light toward the detection area; wherein the ultraviolet light emitted by the ultraviolet emitter Can dissipate in the glass; and a light receiver located above the carrying surface, and the light receiver is used to receive the ultraviolet light emitted by the ultraviolet emitter and reflected by the attachment.

In summary, the glass testing method and glass testing equipment disclosed in the embodiments of the present invention can dissipate into the glass by the ultraviolet light emitted by the ultraviolet emitter and incident on the glass, which is different from the existing glass testing. The device can effectively detect the attachments on the glass (that is, the ultraviolet light emitted by the ultraviolet emitter will not irradiate the non-measured surface of the glass).

The present embodiment discloses a glass testing method and glass testing equipment, and the glass testing equipment 100 is limited to detect attachments 300 on a glass 200. The composition of the glass 200 includes silicon dioxide (SiO ₂ ). The attachment 300 refers to the dirt (such as organic matter or inorganic matter) on the glass 200, and the present invention is not limited herein. From another perspective, any testing equipment that is not used to detect the glass 200 containing silicon dioxide is not equivalent to the glass testing equipment 100 referred to in this embodiment.

Wherein, the glass 200 in this embodiment refers to a high-transmittance glass with a transmittance of at least 90% corresponding to light with a wavelength between 410 nanometers and 810 nanometers. The glass 200 in this embodiment includes a glass body 201, and an anti-infrared layer 203 and an anti-reflection layer 202 formed (or plated) on the opposite surfaces of the glass body 201, respectively. Other not shown in the present invention In other embodiments, the glass 200 may also be one of the anti-infrared layer 203 and the anti-reflection layer 202 formed on only one surface of the glass body 201.

However, the glass 200 of the present invention is not limited to the high transmittance glass in this embodiment. For example, in other embodiments not shown in the present invention, the glass 200 may not be high-transmittance glass; that is, the glass 200 may only include the glass body 201, but not the glass body 201. The body 201 is plated with the anti-infrared layer 203 and the anti-reflection layer 202 described above.

It should be noted that, in order to facilitate the understanding of the glass testing method of this embodiment, the glass testing equipment 100 will be introduced below first, and then the glass testing method using the glass testing equipment 100 will be described, but the present invention is not limited to this. . For example, in other embodiments not shown in the present invention, the glass testing method can also be using other glass testing equipment.

[Glass Test Equipment]

As shown in FIGS. 1 and 2, the glass testing equipment 100 includes a glass stage 1, an ultraviolet emitter located above the glass stage 1, and a light receiver located above the glass stage 1. 3. It should be noted that the ultraviolet emitter 2 and the light receiver 3 may be arranged above the glass stage 1 through a bracket (not shown), but the present invention is not limited to this.

The glass stage 1 includes a bearing surface 11, and the bearing surface 11 is preferably opaque and parallel to a horizontal plane, but the present invention is not limited to this. Wherein, the supporting surface 11 defines a detection area 12 for supporting the glass 200; that is, the position of the detection area 12 of the supporting surface 11 will be related to the setting of the ultraviolet emitter 2 and the light receiver 3 Location.

The light receiver 3 is located above the carrying surface 11, and the light receiver 3 can be used to receive the ultraviolet light L emitted by the ultraviolet emitter 2 and reflected by the attachment 300. Furthermore, the relative positional relationship between the ultraviolet emitter 2 and the light receiver 3 can be set according to the following conditions: the ultraviolet emitter 2 defines a central optical axis C (equivalent to the ultraviolet light UV center line), the light receiver 3 is defined with a central axis P perpendicular to the detection area 12, and the central optical axis C and the central axis P form an included angle less than 90 degrees α .

In this embodiment, the included angle α is approximately 30 degrees as an example, so as to facilitate miniaturization of the glass testing device 100, but the present invention is not limited to this.

The length of the path inside, thereby more effectively dissipating the ultraviolet light UV in the glass 200.

It should be additionally noted that the "ultraviolet light UV incident on the glass 200 and dissipated inside" in this embodiment means that after the ultraviolet light UV enters the glass 200, it will not affect the light reception. Detector 3's detection result. For example: (1) Ultraviolet light UV may be incident on the glass 200, but before reaching the bottom surface of the glass 200 (that is, the non-detection surface), it has dissipated in the glass 200; (2) Ultraviolet light UV may be After being incident on the glass 200 and reaching the bottom surface (ie, the non-detecting surface) of the glass 200, it is reflected by the bottom surface of the glass 200 and dissipated in the glass 200; or (3) ultraviolet rays UV may be incident on the glass 200, and After being reflected by the bottom surface of the glass 200, the remaining and undissipated ultraviolet rays UV only partially pass through the glass 200 (because some of them will be totally reflected), so the above-mentioned ultraviolet rays UV passing out of the glass 200 are already extremely weak and difficult. Affect the detection result of the optical receiver 3.
