Description

TECHNICAL FIELD

[0001] The utility model relates to glass detection technical field especially relates to a glass detection platform. BACKGROUND

[0002] Glass panel is widely used in the field of household appliances, and the existing household appliances, such as induction cooker, microwave oven and the like, cannot do without the use of glass panel, and glass original piece is obtained after processing (such as printing, tempering and the like) glass panel.

[0003] Since the quality of glass original piece will directly affect the quality of glass panel product, glass original piece needs to be detected before production to eliminate glass original piece with defects, so glass panel with internal impurities or bubbles and surface scratches needs to be eliminated before glass panel is made to ensure the quality of product. At present, the detection of glass original piece mainly uses light to irradiate the front or back of glass original piece, and detection workers directly observe glass original piece by naked eye to judge whether glass original piece has impurities, bubbles or scratches. This detection method cannot make the small impurities, bubbles and scratches in glass original piece very prominent, not only requires higher visual detection of detection workers, but also is prone to the problem that defects cannot be detected, therefore, a new type of glass panel detection equipment is proposed to solve the above technical problems. SUMMARY

[0004] The utility model discloses a glass detection platform to solve the above problems.

[0005] To achieve this purpose, the utility model adopts the following technical scheme:

[0006] A glass detection platform, comprising: a base, a light source and a bearing seat, the inside of the base is surrounded to form a detection space with an open top, the base is provided with a lamp groove on at least one inner side wall, and the light source is arranged in the lamp groove, the bearing seat is fixed to the inner side wall of the base, and the bearing seat is used for positioning glass original piece, so that the light emitted by the light source can irradiate into glass original piece from the side wall of glass original piece.

[0007] Preferably, the bearing seat comprises a bearing strip, and the top surface of the bearing strip is lower than the upper wall of the light outlet of the lamp groove.

[0008] Preferably, the bearing seat further comprises a light shielding strip, the light shielding strip is located above the bearing seat, and the bearing seat protrudes from the light shielding strip in the vertical projection direction, and a light transmission channel is formed between the top surface of the bearing strip and the bottom surface of the light shielding strip, and the light transmission channel is communicated with the lamp groove.

[0009] Preferably, the light transmission channel extends along the length direction of the lamp groove.

[0010] Preferably, a background plate is further included, which is arranged at the bottom of the base.

[0011] Preferably, the top surface of the background plate has a height difference with the top surface of the bearing seat.

[0012] Preferably, the base encloses a rectangular structure.

[0013] Preferably, the light source is an LED light bar.

[0014] Preferably, the height of the light transmission channel is 1.5mm-5mm.

[0015] Preferably, the bearing strip protrudes from the light shielding strip by 2mm-4mm.

[0016] One of the embodiments of the utility model has the following beneficial effects:

[0017] 1. The light source in the lamp groove irradiates into the glass original piece from the side wall of the glass original piece. Since the inner surface of the glass original piece can reflect light, the light irradiated into the glass original piece can be continuously reflected in the glass original piece. At this time, the glass original piece as a whole will become very transparent. However, when there are defects such as dust and bubbles in the glass original piece, since the light is continuously reflected in the glass original piece, when the light is reflected to the surface of the defects such as dust and bubbles, the surface of the defects such as dust and bubbles will exhibit a visual effect of emitting light, so that the defects such as dust and bubbles in the glass original piece will be clearly displayed.

[0018] 2. Since the utility model adopts the method of lighting from the side of the glass original piece for detection, when the glass original piece is detected, it is not easy to be disturbed by other light, so that the defects such as dust and bubbles in the glass original piece can be easily observed.

[0019] 3. The base encloses a rectangular shape, and the lamp groove is arranged on each of the three inner sides of the base. When the glass original piece is detected, the two sides of the glass original piece are respectively close to two inner sides of the base. In this way, the light intensity in the glass original piece is larger by lighting the two sides of the glass original piece, so that the defects in the glass original piece are more obvious, thereby obtaining better detection effect.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment provides a glass testing stage, such as... Figures 1-4 As shown, it includes: a base 1, a light source 2, and a support 3; the interior of the base 1 forms a top-open detection space 11, and the base 1 has a lamp groove 12 on at least one inner side wall, and the light source 2 is disposed in the lamp groove 12; the support 3 is fixed to the inner side wall of the base 1, and the support 3 is used to position the glass sheet 5 so that the light emitted by the light source 2 can shine into the glass sheet 5 from the side wall of the glass sheet 5.

[0032] During the inspection of the original glass sheet 5, the bottom surface of the original glass sheet 5 is first placed against the support 3, so that the side of the original glass sheet 5 is close to and aligned with the lamp groove 12. The light source 2 in the lamp groove 12 shines into the original glass sheet 5 from the side wall. Since the inner surface of the original glass sheet 5 can reflect light, the light shining into the original glass sheet 5 by the light source 2 is continuously reflected within the original glass sheet 5. At this time, the original glass sheet 5 becomes very clear. However, when there are defects such as dust or bubbles inside the original glass sheet 5, because the light is continuously reflected inside the original glass sheet 5, when the light is reflected onto the surface of the defects such as dust or bubbles, the surface of the defects will exhibit a luminous visual effect, thus making the glass... The dust, bubbles, and other defects inside the original glass sheet 5 will be clearly displayed. Furthermore, because the side of the original glass sheet 5 is very close to the light source 2, the light intensity entering the original glass sheet 5 is relatively high. When the light reflects onto the surface of the dust, bubbles, and other defects, the surface brightness of these defects is high. Therefore, not only can the dust, bubbles, and other defects inside the original glass sheet 5 be made more obvious, but they can also be easily distinguished from the dust on the surface of the original glass sheet 5. Since this invention uses side lighting for inspection, it is less susceptible to interference from other light sources when inspecting the original glass sheet 5, thus allowing for easy observation of the dust, bubbles, and other defects inside the original glass sheet 5. Specifically… Currently, most glass substrate inspections involve illuminating the substrate from either the front or back (the front side refers to the side of the substrate closest to the observation point, while the back side is the other side). When illuminating the front side, the reflective outer surface causes some light to refract and penetrate the substrate, while some is reflected. This reflected light significantly interferes with the inspection, necessitating constant adjustments to the viewing angle to detect defects. This process is prone to errors. The problem is that dust adhering to the front of the glass sheet 5 can be easily missed, and because the dust surface is illuminated by light, it also has a luminous visual effect, which can be confused with the defects inside the glass sheet 5, thus easily leading to false detection. Similarly, when the back of the glass sheet 5 is illuminated, the light can penetrate the glass sheet 5 and illuminate the front of the glass sheet 5. Therefore, when observing the glass sheet 5 from the front, it will also be subject to greater light interference, thus making it difficult to detect the defects inside the glass sheet 5. This utility model cleverly solves the problem of light interference in the detection process by illuminating the side of the glass sheet 5, making it easier to detect the defects inside the glass sheet 5.

[0033] Furthermore, the support base 3 includes a support strip 31, the top surface of which is lower than the upper wall of the light outlet of the lamp groove 12.

[0034] The support strip 31 is used to position the glass sheet 5. During testing, the bottom surface of the glass sheet 5 is placed against the top surface of the support strip 31. Since the top surface of the support 3 is lower than the upper wall of the light outlet of the lamp groove 12, when the bottom surface of the glass sheet 5 is against the top surface of the support strip 31, at least part of the side surface of the glass sheet 5 is aligned with the light outlet of the lamp groove 12, so that the light source 2 can illuminate the side surface of the glass sheet 5. Of course, as a preferred embodiment, the top surface of the support 3 is aligned with the lower wall of the light outlet of the lamp groove 12, so that the overlap area between the side surface of the glass sheet 5 and the light outlet of the lamp groove 12 is larger, so that more light can illuminate the glass sheet 5, thereby improving the testing effect.

[0035] Furthermore, the support base 3 also includes a light-shielding strip 32, which is located above the support base 3 and protrudes from the light-shielding strip 32 in the vertical projection direction. A light-transmitting channel 33 is formed between the top surface of the support strip 31 and the bottom surface of the light-shielding strip 32, and the light-transmitting channel 33 is connected to the lamp groove 12.

[0036] Since the light emitted by the light source 2 is divergent, in order to prevent the light source 2 from shining on the inspection operator or visual inspection equipment, this utility model sets a light-shielding strip 32 to block the light. A light-transmitting channel 33 is formed between the light-shielding strip 32 and the support strip 31. Some of the light from the light source 2 passes through the light-transmitting channel 33 and shines out, while the rest of the light is blocked by the support strip 31 and the light-shielding strip 32, thereby preventing the light from the light source 2 from interfering with the inspection of the glass sheet 5.

[0037] Furthermore, the light-transmitting channel 33 extends along the length direction of the lamp groove 12.

[0038] This arrangement allows the light-transmitting channel 33 to correspond with the lamp slot 12, enabling more light to reach the side of the glass substrate 5 and thus improving the detection effect.

[0039] Furthermore, it also includes a background plate 4, which is disposed at the bottom of the base 1.

[0040] By setting the background plate 4, the defects inside the glass sheet 5 can be clearly contrasted with the background plate 4 when the glass sheet 5 is inspected, making the defects inside the glass sheet 5 more prominent. As a preferred embodiment, the background plate 4 has a darker color, such as black, so that the defects inside the glass sheet 5 can be clearly contrasted with the background plate, and the defects inside the glass sheet 5 can be more easily detected.

[0041] Furthermore, there is a height difference between the top surface of the background plate 4 and the top surface of the support 3.

[0042] When inspecting the original glass sheet 5, the original glass sheet 5 does not contact the background plate 4, that is, the original glass sheet 5 is suspended above the background plate 4. This creates a visual focus difference between the original glass sheet 5 and the background plate 4. When the visual focus is on the original glass sheet 5, even if there is dust on the background plate 4, it will not cause false detection, thus avoiding interference from dust or other factors on the background plate 4. In addition, this also prevents dust on the background plate 4 from adhering to the surface of the original glass sheet 5 during the inspection process.

[0043] Furthermore, the base 1 forms a rectangular structure.

[0044] In one implementation, the base 1 is rectangular, and light grooves 12 are respectively provided on three of the inner sides of the base 1. When inspecting the glass sheet 5, the two sides of the glass sheet 5 are respectively placed close to the two inner sides of the base 1. In this way, by shining light on the two sides of the glass sheet 5, the light intensity inside the glass sheet 5 is greater, making the defects inside the glass sheet 5 more obvious, thereby obtaining a better inspection effect. In addition, by increasing the size of the base 1, two inspection stations can be set in one base 1, which not only reduces equipment costs, but also makes the structure of the inspection station more compact. Compared with setting two inspection stations, it takes up less space and helps to reduce production costs.

[0045] Furthermore, the light source 2 is an LED light strip.

[0046] Using LED light strips has the advantages of high brightness and uniform light, which makes the light more uniform throughout the glass sheet 5 during inspection, thus making every defect inside the glass sheet 5 stand out very clearly.

[0047] Furthermore, the height of the light-transmitting channel 33 is 1.5mm to 5mm.

[0048] When the height of the light transmission channel 33 is less than 1.5 mm, the light intensity illuminating the side of the glass substrate 5 is reduced due to the excessive narrowness of the light transmission channel 33, making it difficult to achieve the required detection effect. When the height of the light transmission channel 33 is greater than 5 mm, the width of the light-shielding strip 32 needs to be increased so that the light-shielding strip 32 can play a light-shielding role. However, this will also reduce the light intensity illuminating the side of the glass substrate 5, affecting the detection effect.

[0049] Furthermore, the support strip 31 protrudes 2mm to 4mm beyond the light-shielding strip 32.

[0050] During testing, the support strip 31 serves to support the glass sheet 5. The edge of the glass sheet 5 is supported by the portion of the support strip 31 that protrudes from the light-shielding strip 32. Of course, to achieve a better positioning effect, the side of the glass sheet 5 can rest against the side of the light-shielding strip 32. This will not obstruct the glass sheet 5, but will also position the glass sheet 5 so that the side of the glass sheet 5 is aligned with the light-transmitting channel 33. When the width of the support strip 31 protruding from the light-shielding strip 32 is less than 2mm, the area supporting the glass sheet 5 is too small, making it difficult to place the glass sheet 5 on the support strip 31 and easily breaking it. When the width of the support strip 31 protruding from the light-shielding strip 32 is greater than 4mm, the area of ​​the glass sheet 5 obstructed by the support strip 31 is too large, affecting the testing effect of the glass sheet 5.
