Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Referring to fig. 1 to 5, the present invention discloses a lighting device for a curved glass inspection machine, including:

a first lamp source assembly 100 disposed on one side of the curved glass 300, the first lamp source assembly 100 comprising: at least one light emitter 120; at least one reflection plate 140, wherein the reflection plate 140 has a plurality of reflection regions, and the plurality of reflection regions are arranged in an arc shape;

and the second light source assembly 200 is arranged on one side of the curved glass 300 far away from the first light source assembly 100.

Specifically, in the present embodiment, the first light source assembly 100 and the second light source assembly 200 are disposed at opposite sides of the curved glass 300 respectively to provide light rays in different paths and directions, so that the curved glass 300 can be illuminated more comprehensively during the detection process, and omission of the detector due to poor illumination conditions is reduced.

Further, in the first light source assembly 100, a plurality of reflection regions are disposed, and the plurality of reflection regions are arranged in an arc shape, and the light emitted by the light emitting body 120 reaches the curved glass 300 after being reflected by the reflection regions. In the process, the plurality of reflecting areas are arranged in an arc shape, so that the light rays can form a plurality of illuminating light rays with different angles after being reflected by the reflecting plate 140, the requirement of the curved glass 300 on the quantity of the light rays with different angles can be met, and the problem that the detection machine is missed to detect due to poor illumination caused by the arc-shaped curved glass 300 is solved.

Preferably, the first lamp source assembly 100 includes two reflecting plates 140 and two luminous bodies 120, a gap 130 for transmitting light is formed between the two luminous bodies 120, and the two reflecting plates 140 are symmetrical with respect to the gap 130.

The two luminous bodies 120 are symmetrical with respect to the gap 130, the two reflective plates 140 are symmetrical with respect to the gap 130, and the gap 130 is for transmitting light. Generally, the collecting camera 400 is disposed right above the gap 130, and detects the curved glass 300 through the gap 130; that is to say, the two light emitters 120 are symmetrical with respect to the collecting camera 400, and the two reflective plates 140 are also symmetrical with respect to the collecting camera 400, so that the whole lighting environment (including parameters such as angles, paths, directions and overlapping of light rays) is symmetrical with respect to the collecting camera 400, so that the light rays received by each part of the curved glass 300 are more uniform, and further, the phenomenon that each part of the curved glass 300 interferes with detection due to different light ray conditions is avoided.

Preferably, each of the reflective plates 140 is provided with 14 reflective regions, and the light emitter 120 includes a plurality of lamp beads.

Each of the reflective plates 140 has 14 reflective regions, so that the first lamp assembly 100 can provide 28 reflective regions, and the 28 reflective regions are symmetrically arranged to provide more sufficient light under the condition of uniform illumination.

Preferably, the reflection region includes a plurality of first reflection surfaces 141 and a plurality of second reflection surfaces 142, one second reflection surface 142 is disposed between any two adjacent first reflection surfaces 141, and one first reflection surface 141 is disposed between any two adjacent second reflection surfaces 142. In a popular way, the first reflective surfaces 141 and the second reflective surfaces 142 are arranged in a staggered manner, so that the reflected light of the first reflective surfaces 141 and the reflected light of the second reflective surfaces 142 are more uniform.

Each of the reflective regions includes a first reflective surface 141 and a second reflective surface 142, so that the light rays can form more angles of reflected light after being reflected by the reflective regions, thereby providing more angles of illumination.

Preferably, the first reflecting surface 141 and the second reflecting surface 142 are both planar surfaces, and an included angle between the first reflecting surface 141 and the second reflecting surface 142 is an obtuse angle.

It can be understood that, if the included angle between the first reflecting surface 141 and the second reflecting surface 142 is a right angle, when the illumination light is perpendicular to one of the reflecting surfaces, the other reflecting surface is parallel to the illumination light and cannot be reflected; similarly, if the included angle between the first reflective surface 141 and the second reflective surface 142 is an acute angle, the range of angles of the light beams reflected by the first reflective surface and the second reflective surface is smaller. Therefore, the included angle between the first reflecting surface 141 and the second reflecting surface 142 is an obtuse angle, so that the angle range of the light reflected by the first reflecting surface 141 and the second reflecting surface 142 is wider, the quantity of the light reflected is greater, and the lighting environment of the curved glass 300 is further improved.

Preferably, the plurality of reflective regions gradually get closer to the light emitter 120 along the curved glass 300 towards the first light source assembly 100; namely, the plurality of reflecting regions are arranged in an arc shape, and the distance from the reflecting region closer to the light emitting body 120 to the curved glass 300 is larger, and the distance from the reflecting region farther from the light emitting body 120 to the curved glass 300 is smaller; the lengths of the paths through which the light emitted from the light emitting body 120 is reflected to the curved glass 300 through the different reflection regions are equal, so that the light beam reaching the curved glass 300 is more uniform.

An included angle formed by the first reflecting surface 141 and a tangent line of the point to be detected on the curved glass 300 is a first included angle, and the plurality of first included angles gradually decrease from the curved glass 300 towards the first light source assembly 100;

the included angle that second plane of reflection 142 and the tangent line of the point position of awaiting measuring on the curved glass 300 become is the second included angle, and is a plurality of the second included angle is towards by curved glass 300 first light source subassembly 100 direction reduces gradually.

It should be noted that, during detection, it is necessary to ensure that the tangential direction of the detection point is always perpendicular to the acquisition camera 400, so as to improve the accuracy of detection.

As shown in fig. 1-2, assuming that the capturing camera 400 is in the vertical direction, the tangent line of the detection point is in the horizontal direction, and the lowest point of the curved glass 300 is the detection point. The first angle/the second angle described in the present embodiment can be understood as an angle between the first reflecting surface 141/the second reflecting surface 142 and a horizontal plane. And the plurality of first included angles/second included angles along the curved glass 300 towards the first light source component 100 are gradually reduced, so that the first included angle/second included angle closer to the light emitting body 120 is smaller, and the first included angle/second included angle farther away from the light emitting body 120 is larger, so that light rays reflected by different reflecting regions can be finally converged to the detection point position on the curved glass 300, and the angles of the converged light rays are different, thereby providing sufficient and multi-angle illumination for the detection point position.

Further, as shown in FIGS. 2-3, the first included angle of the first reflective surface 141 closest to the curved glass 300 is approximately 90, while the first included angle of the first reflective surface 141 farthest from the curved glass 300 is between 0 and 45.

Preferably, the lamp further comprises a box body 110, wherein the first lamp source assembly 100 is arranged in the box body 110;

the box body 110 is provided with an end surface 111 and a plurality of side surfaces 112, the end surface 111 is provided with a notch 113, and the notch 113 is communicated with the gap 130 for light transmission; the end of the box 110 away from the end surface 111 has an opening facing the curved glass 300.

The case 110 is provided, and the first lamp source assembly 100 is disposed in the case 110, so that the light emitted from the first lamp source assembly 100 cannot pass through, and finally reaches the curved glass 300 through a series of reflections, thereby providing better lighting conditions.

Meanwhile, the box body 110 can isolate external light to avoid the interference of the external light.

Specifically, the detection point location, the gap 130, the notch 113 and the collecting camera 400 are located on the same straight line, which facilitates the direct and accurate detection of the detection point location by the collecting camera 400.

Preferably, the second lamp source assembly 200 includes two compensating light sources 210, and the two compensating light sources 210 are respectively disposed at opposite sides of the curved glass 300.

It can be understood that the first light source assembly 100 is disposed on the upper surface of the curved glass 300, most of the light in the first light source assembly 100 is reflected and transmitted after reaching the upper surface of the curved glass 300, and if the quantity of the transmitted light is insufficient, the lighting of the lower surface of the curved glass 300 is insufficient, and the detection of the lower surface by the detector is prone to be misjudged. Therefore, in the present embodiment, two compensation light sources 210 are disposed on one side of the curved glass 300 away from the first light source assembly 100, so as to compensate for the insufficient color-transmitting light of the first light source assembly 100, and the first light source assembly 100 and the second light source assembly 200 provide 30 light sources for the detector in total.

Preferably, two of the compensation light sources 210 are symmetrical with respect to the curved glass 300.

The two compensating light sources 210 are symmetrical, so that the light reaching the curved glass 300 by the second light source assembly 200 is more uniform.

Preferably, an included angle formed by the irradiation direction of the compensation light source 210 and a tangent line of the point to be detected on the curved glass 300 is between 30 ° and 60 °.

The included angle is set to be between 30 degrees and 60 degrees, so that the compensation light source 210 can reach the acquisition camera 400 through the gap 130 and the notch 113 after being transmitted by the curved glass 300, and the acquisition camera 400 cannot acquire the light beams due to overhigh brightness caused by excessive light beam transmission is avoided.
