Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass detection, and more specifically to a tempered glass detection device. Background Art

[0002] During the production process of tempered glass, it is necessary to inspect and detect its appearance quality to ensure the product quality. Appearance quality problems of tempered glass occur at different stages of the production process, and generally can be divided into the following two categories: 1. Appearance quality problems of tempered glass caused by quality defects of the original sheet, such as: dot-like defects (bubbles, inclusions), scratches, optical distortion, etc.; 2. Appearance quality problems caused by the tempering process, such as: flatness problems of tempered glass, optical problems (such as ripple, stress spot phenomenon), etc. These above appearance quality problems will not only cause unaesthetic problems such as image bending during use, but may even cause unexpected fragmentation of tempered glass due to stress.

[0003] Currently, in the industry, the detection technology for detecting tempered glass during production generally uses probe detection, using a probe to perform single-point detection of whether there are depressions or protrusions on the surface of the tempered glass. However, this detection technology method cannot conduct a comprehensive detection. At the same time, this method is time-consuming, has poor effects, and has a relatively high probability of omission.

[0004] On the other hand, although most tempered glass is required to have a flat surface, there are also some tempered glass that require a curved surface, and the probe detection method cannot complete the detection of whether the curvature of the curved tempered glass meets the regulations.

[0005] The solution of the present invention aims at the above technical defects existing in the prior art, and designs a detection device for tempered glass. It can not only more reasonably, quickly and comprehensively judge whether the surface of the tempered glass is flat, but also image-determine whether there are appearance quality problems on the surface of the tempered glass. At the same time, it can also judge whether the curvature of the curved tempered glass meets the product regulations, improving the production detection level of tempered glass and ensuring the product quality of the produced products. Summary of the Invention

[0006] What the present invention discloses is a tempered glass detection device, and its main purpose is to overcome the above-mentioned deficiencies and drawbacks existing in the prior art.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A toughened glass detection device includes a conveying table and an inspection base. A conveyor belt and rollers are cooperatively installed on the conveying table, and the rollers drive the conveyor belt to roll and convey the toughened glass. The inspection base is cooperatively erected at both ends of the conveying table. A plurality of pivot plates are provided on the inspection base, and the pivot plates are pivotally connected in sequence.

The linear light source emitted by the infrared light emitter can pass through the detection hole and be received by the infrared light receiver. A cross bar is further erected on the front side of the inspection base, and a plurality of visible light receivers are installed and arranged on the cross bar. A visible light emission source is installed at the bottom of the pivot plate. The light source emitted by the visible light emission source irradiates on the passing toughened glass and is reflected and transmitted to the visible light receivers. An image processor is cooperatively installed on the visible light receivers, and the image processor is used to receive and process the visible light source image reflected and transmitted.

[0009] Furthermore, a warning device is also provided on the conveying table, and the warning device is connected to the visible light receivers for emitting warning messages.

[0010] Furthermore, the warning device is any one of a light warning device, a sound warning device or a text warning device.

[0011] Furthermore, a reflecting lens is provided in the detection hole, and the installation angle of the reflecting lens can be adjusted movably. The linear light source emitted by the infrared light emitter is reflected by the reflecting lens and then transmitted through the detection hole.

[0012] Furthermore, an aperture baffle is cooperatively installed on the detection hole, and the aperture baffle is used to adjust the aperture size of the detection hole.

[0013] Furthermore, the infrared light emitter and the infrared light receiver are in the same horizontal position.

[0014] Furthermore, there are two detection holes on the pivot plate, and they are arranged in a horizontally symmetric structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] AsFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 , a toughened glass detection device includes a conveying table 1 and an inspection base 2. A conveyor belt 11 and rollers 12 are fitted on the conveying table 1. The rollers 12 drive the conveyor belt 11 to roll and convey the toughened glass 3. The inspection base 2 is fitted and erected at both ends of the conveying table 1. A number of pivot plates 4 are provided on the inspection base 2. The pivot plates 4 are pivotally connected in sequence. A roller 41 is provided at the bottom of the pivot plate 4. The roller 41 movably rolls against the upper surface of the toughened glass 3. A detection hole 42 with adjustable aperture is installed above the pivot plate 4. An infrared light emitter 43 and an infrared light receiver 44 are respectively provided on the left and right sides of the inspection base 2. The linear light source emitted by the infrared light emitter 43 can pass through the detection hole 42 and be received by the infrared light receiver 44. By providing the inspection base 2, the pivot plate 4, the detection hole 42, the infrared light emitter 43 and the infrared light receiver 44, the present invention can detect whether the flatness of the surface of the toughened glass 3 meets the requirements.

[0032] A cross bar 5 is further erected on the front side of the inspection base 2. A number of visible light receivers 51 are installed on the cross bar 5. A visible light emission source 6 is installed at the bottom of the pivot plate 4. The light source emitted by the visible light emission source 6 irradiates on the passing toughened glass 3 and is reflected and transmitted to the visible light receivers 51. An image processor 52 is fitted on the visible light receivers 51. The image processor 52 is used to receive and process the visible light source image reflected and transmitted. By providing the cross bar 5, the visible light receivers 51, the visible light emission source 6 and the image processor 52, the present invention can use high-frequency image comparison to determine in real time whether there are appearance quality problems on the surface of the toughened glass 3 and locate the position.

[0033] Furthermore, a warning device 7 is also provided on the conveying table 1. The warning device 7 is connected to the visible light receivers 51 and is used to send warning messages.

[0034] Furthermore, the warning device 7 is any one of a light warning device, a sound warning device or a text warning device. The present invention can issue corresponding warnings through the warning device 7 to remind timely handling and improve the detection level of toughened glass.

[0035] Furthermore, an aperture baffle 421 is fitted on the detection hole 42. The aperture baffle 421 is used to adjust the aperture size of the detection hole 42.

[0036] Furthermore, the infrared light emitter 43 and the infrared light receiver 44 are at the same horizontal position.

[0037] Furthermore, there are two detection holes 42 on the pivot plate 4, which are horizontally symmetrically arranged.

[0038] The processor 52 of the present invention compares the images received by the visible light receiver at a high frequency (from 1200 times per second to 6000 times per second), thereby enabling real-time determination of which part of the tempered glass has appearance quality problems and transmitting a warning signal. Among them, since the present invention only obtains different images when the tempered glass has bumps, grooves, wave streaks or stress marks, it is easy to determine whether there are appearance quality problems with the tempered glass. Among them, the more the number of visible light emitters / visible light receivers, the higher the detection precision. The comparison frequency of the processor of the present invention can be as high as thousands of times per second. Therefore, even if the tempered glass moves rapidly on the conveyor table, the present invention can easily determine whether there are appearance quality problems with the tempered glass. Moreover, the present invention only needs to determine whether the front and rear images are different. Therefore, for example, positive and negative films can be alternately used to process the captured images, thereby greatly increasing the accuracy of judgment. For example, first judge the captured image in the positive film mode, then process the captured image in the negative film mode, and then make a judgment again to verify and proofread the detection result.

[0039] The following is the specific use process of the present invention:

[0040] Step 1: Alignment of detection holes

[0041] First, adjust the positions of the detection holes on the pivot plate so that the positions of the detection holes of each pivot plate are at the same horizontal position, and the straight light can smoothly pass through each detection hole.

[0042] Step 2: Emit infrared light source and receive red light source

[0043] Start the infrared light emitter to emit an infrared light source that is linearly transmitted. After this light source passes through the detection holes on the pivot plate, it is received by the infrared light receiver. Then the surface of the tempered glass is flat. If the infrared light receiver does not receive this infrared light source, it means that the surface of the tempered glass is uneven.

[0044] Step 3: Emit visible light emitter and identify and judge the reflected image

[0045] Start the visible light emitter to emit a visible light source. After the visible light source irradiates the tempered glass, it is reflected and transmitted to the visible light receiver. The processor on this visible light receiver performs image recognition and judgment on the received light source, compares the image situation on the surface of the tempered glass. When it is recognized that there are optical problems such as wave streaks or application spots on the glass surface, the position with appearance quality can be located. At the same time, a warning signal is sent to achieve real-time detection of the surface quality of the tempered glass.

[0046] Embodiment 2

[0047] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 shown, a toughened glass detection device includes a conveying table 1 and an inspection base 2. A conveyor belt 11 and rollers 12 are cooperatively installed on the conveying table 1. The rollers 12 drive the conveyor belt 11 to roll and convey the toughened glass 3. The inspection base 2 is cooperatively erected at both ends of the conveying table 1. A plurality of pivot plates 4 are provided on the inspection base 2. The pivot plates 4 are pivotally connected in sequence. A roller 41 is provided at the bottom of the pivot plate 4. The roller 41 movably abuts against the upper surface of the toughened glass 3. A detection hole 42 with adjustable aperture is installed above the pivot plate 4. An infrared light emitter 43 and an infrared light receiver 44 are respectively arranged on the left and right sides of the inspection base 2. The linear light source emitted by the infrared light emitter 43 can pass through the detection hole 42 and be received by the infrared light receiver 44. By providing the inspection base 2, the pivot plate 4, the detection hole 42, the infrared light emitter 43 and the infrared light receiver 44, the present invention can detect whether the flatness of the surface of the toughened glass 3 meets the requirements.

[0048] A cross bar 5 is further erected on the front side of the inspection base 2. A plurality of visible light receivers 51 are installed and arranged on the cross bar 5. A visible light emission source 6 is installed at the bottom of the pivot plate 4. The light source emitted by the visible light emission source 6 irradiates on the passing toughened glass 3 and is reflected and transmitted to the visible light receivers 51. An image processor 52 is installed in a supporting manner on the visible light receivers 51. The image processor 52 is used to receive and process the visible light source image reflected and transmitted. By providing the cross bar 5, the visible light receivers 51, the visible light emission source 6 and the processor 52, the present invention can use high-frequency image comparison to determine in real time whether there are appearance quality problems on the surface of the toughened glass 3 and locate the position.

[0049] Furthermore, a warning device 7 is further provided on the conveying table 1. The warning device 7 is connected to the visible light receivers 51 and is used to issue a warning message.

[0050] Furthermore, the warning device 7 is any one of a light warning device, a sound warning device or a text warning device. The present invention can issue corresponding warnings through the warning device 7 to remind timely handling and improve the detection level of toughened glass.

[0051] Furthermore, a reflective lens 8 is disposed in the detection hole 42. The installation angle of the reflective lens 8 can be adjusted movably. After the linear light source emitted by the infrared light emitter 43 is reflected by the reflective lens 8, it is transmitted through the detection hole 42. By providing the reflective lens 8, the detection hole 42 and the pivot plate 4, the present invention can effectively judge the appearance quality of the surface of the arc-shaped tempered glass, and can also detect whether the bending angle of the arc-shaped surface conforms to the actual product parameters, improving the product detection quality.

[0052] Furthermore, a hole diameter baffle 421 is fitted on the detection hole 42. The hole diameter baffle 421 is used to adjust the hole diameter size of the detection hole 42.

[0053] Furthermore, the infrared light emitter 43 and the infrared light receiver 44 are in the same horizontal position. Furthermore, there are two detection holes 42 on the pivot plate 4, which are arranged in a horizontally symmetric structure. Furthermore, there are two groups of inspection bases 2, which are sequentially fitted on the conveying table 1.

[0054] The following is the specific use process of the present invention:

[0055] Step 1: Detection hole alignment

[0056] First, adjust the position of the detection hole on the pivot plate so that the linear light can smoothly pass through each detection hole.

[0057] Step 2: Emit infrared light source and receive red light source

[0058] Start the infrared light emitter to emit an infrared light source transmitted linearly. After the light source passes through the detection hole on the pivot plate, it is reflected by the reflective lens and then passes through the detection hole. Finally, the reflected infrared light source is received by the infrared light receiver, indicating that the surface of the arc-shaped tempered glass is flat and its radian meets the requirements; if the infrared light receiver does not receive the infrared light source, it means that the surface of the arc-shaped tempered glass is uneven and its bending radian does not meet the parameter requirements.

[0059] Step 3: Emit visible light emission source and identify and judge the reflected image

[0060] Start the visible light emission source to emit a visible light source. After the visible light source irradiates the tempered glass, it is reflected and transmitted to the visible light receiver. The processor on the visible light receiver performs image recognition and judgment on the received light source, compares the image situation on the surface of the tempered glass. When optical problems such as wave streaks or application spots are identified on the glass surface, the position with appearance quality can be located, and at the same time, a warning signal is sent to realize the real-time detection of the surface quality of the tempered glass.

[0061] The difference between this embodiment and the first embodiment is that by adding a reflective lens, the bending flatness of the surface of the curved tempered glass can be detected in real time. At the same time, by setting multiple groups of inspection bases, the tempered glass can be detected and processed more accurately.

[0062] From the above specific description of the embodiments of the present invention, it can be seen that compared with the existing detection equipment, the present invention has the following advantages:

[0063] 1. It can detect flatness, ripple marks and stress spots simultaneously, and can also judge whether the tempered glass is bent, and even can judge whether the degree of bending meets the requirements.

[0064] 2. During the conveying process of the tempered glass, it can detect in real time whether there are appearance quality problems with the tempered glass.

[0065] 3. During the conveying process of the tempered glass, it can improve in real time the areas with appearance quality problems.

[0066] 4. It has multiple pivot plates and adjustable detection hole parts, which can determine whether the tempered glass is warped.

[0067] 5. By changing the aperture of the detection hole of the adjustable detection hole part, the detection precision of the degree of bending can be adjusted.

[0068] 6. By high-frequency image comparison, it can determine in real time whether there are appearance quality problems with the tempered glass.

[0069] 7. Through the operation of the processor, it can determine in real time which part of the tempered glass has appearance quality problems and issue a warning.

[0070] 8. By combining multiple detection methods, it can determine multiple appearance quality problems in real time.

[0071] 9. Users can add multiple groups of tempered glass detection devices according to actual needs, which can improve the accuracy of detection.

[0072] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive improvement made to the present invention using this concept should belong to the act of infringing the protection scope of the present invention.
