Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0040] In the present application, unless otherwise clearly specified and limited, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0042] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0043] Embodiments of the present application provide a glass detection device. Please refer to Figure 1 and Figure 2 , the glass detection device includes a box body 1, a conveyor belt 2, a bracket 3, a first optical detection module 4, a second optical detection module 5 and a control module 6. The box body 1 forms a detection space 110. Opposite ends of the detection space 110 in the horizontal direction are respectively provided with an inlet 120 and an outlet 130; the conveyor belt 2 is used to convey the glass 8 from the inlet 120 to the outlet 130; the bracket 3 is arranged on the conveyor belt 2, and the glass 8 is arranged on the bracket 3 in the vertical direction; the first optical detection module 4 includes a UV light source module 410UV and a light signal receiving module 420 arranged in the detection space 110. The UV light source module 410UV and the light signal receiving module 420 are respectively arranged on opposite sides of the conveyor belt 2. The light emitted by the UV light source module 410UV is perpendicular to the plate surface of the glass 8. The light signal receiving module 420 detects the flatness and smoothness of the glass 8 by receiving the light transmitted through the glass 8; the second optical detection module 5 is arranged directly above the conveyor belt 2. The second optical detection module 5 detects the thickness of the glass 8 and the edge breakage degree of the glass 8 by laser; the control module 6 is respectively communicatively connected to the conveyor belt 2, the first optical detection module 4 and the second optical detection module 5.

[0044] For the first optical detection module 4, the UV light source module 410UV emits ultraviolet light perpendicular to the plate surface of the glass 8 on one side of the glass 8. The light signal receiving module 420 includes a plurality of photoelectric signal receivers arranged in an array on the other side of the glass 8. If the glass 8 is flat and the plate surface is not damaged, the path of the ultraviolet light transmitted through the glass 8 will not change, and the ultraviolet light received by each photoelectric signal receiver is relatively uniform; if the glass 8 is not flat or the plate surface is damaged, the path of the ultraviolet light transmitted through the defective area of the glass 8 will change. At this time, the ultraviolet light received by the photoelectric signal receiver is no longer uniform, and thus it can be determined that there are defects in the glass 8.

[0045] For the second optical detection module 5, the thickness detection and edge breakage detection of the glass 8 are carried out separately. Therefore, the second optical detection module 5 includes two sets of laser detection devices, which are integrated together. The thickness detection is mainly based on the principle of laser triangulation. This principle involves a focused laser beam directed at the edge of the glass 8. The beam reflected by the glass 8 passes through a filter and a receiving lens, and finally forms a front surface imaging waveform on the linear array CMOS device. By measuring the centroid coordinates of the front surface imaging waveform and its position relationship with the front surface, the thickness measurement of the transparent object can be realized according to the principle of laser triangulation. The edge breakage detection depends on the interaction between the laser beam and the edge of the glass 8. By measuring the reflected and scattered optical signals, the surface state of the object is analyzed. When the laser beam irradiates the edge of the glass 8, if there is a break at the edge, the reflection and scattering conditions of the laser beam will change. These changes include the intensity and direction of the reflected light and the distribution of the scattered light. These changes can be captured by the receiver and converted into electrical signals for processing. By analyzing these electrical signals, it can be determined whether there is a break at the object edge, as well as the degree and position of the break.

[0046] In the embodiment of the present application, the glass detection device includes a box body 1, a conveyor belt 2, a bracket 3, a first optical detection module 4, a second optical detection module 5, and a control module 6. The conveyor belt 2 conveys the glass 8 from the inlet 120 of the box body 1 to the outlet 130 of the box body 1. The glass 8 is vertically arranged on the bracket 3 on the conveyor belt 2. The UV light source module 410UV and the optical signal receiving module 420 of the first optical detection module 4 are respectively arranged on the opposite sides of the conveyor belt 2. The light emitted by the UV light source module 410UV is perpendicular to the plate surface of the glass 8. The optical signal receiving module 420 detects the flatness and smoothness of the glass 8 by receiving the light transmitted by the glass 8. The second optical detection module 5 directly above the conveyor belt 2 detects the thickness of the glass 8 and the edge breakage of the glass 8 by laser. Through the mutual cooperation of the first optical detection module 4 and the second optical detection module 5, the automatic detection of the glass 8 is realized, the detection efficiency is improved, the possibility of the glass 8 being secondarily contaminated is reduced, the possibility of the detection damaging the glass 8 is reduced, the labor intensity of the staff is reduced, and the possibility of the staff being injured is reduced.

[0051] In one embodiment, refer to Figure 2 , a rotating mechanism 7 for rotating the glass 8 is provided on the bracket 3. The rotating mechanism 7 includes two rollers 710 and at least one rotation driving mechanism 720. The two rollers 710 are rotatably mounted on the bracket 3. The bottom of the glass 8 is placed on the two rollers 710. The rotation driving mechanism 720 is used to drive the rollers 710 to rotate so as to drive the glass 8 to rotate.

[0052] With the above settings, during the process of the conveyor belt 2 transporting the glass 8, the rotation driving mechanism 720 rotates the glass 8 in real time, and timely exchanges the bottom and top of the glass 8, so that the first optical detection module 4 and the second optical detection module 5 can detect the entire glass 8, improving the detection accuracy.

[0053] In one embodiment, the rollers 710 are made of an elastic material to avoid damaging the glass 8.

[0054] In one embodiment, please refer to Figure 1 and Figure 2 , the control module 6 includes a first optoelectronic signal processor 610 and a second optoelectronic signal processor 620. The first optoelectronic signal processor 610 is electrically connected to the optical signal receiving module 420, and the second optoelectronic signal processor 620 is electrically connected to the second optical detection module 5.

[0055] In this way, each of the first optical detection module 4 and the second optical detection module 5 is equipped with a processor, improving the data processing speed.

[0056] In one embodiment, refer to Figure 1 , the control module 6 further includes a display screen 630. The display screen 630 is communicatively connected to the first optoelectronic signal processor 610 and the second optoelectronic signal processor 620 respectively. The display screen 630 can display the processing data of the first optoelectronic signal processor 610 and the second optoelectronic signal processor 620, facilitating the staff to view.

[0057] In one embodiment, refer to Figure 1 , the display screen 630 is arranged on the outer side surface of the box body 1.

[0058] In one embodiment, the box body 1 is a clean box. The clean box can provide a locally dust-free and sterile working environment, avoiding secondary contamination of the glass 8, and can also protect the safety of the sample and the staff.

For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0060] The above-described embodiments only express several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
