[0032] The photovoltaic glass detection device will be described below in conjunction with the accompanying drawings.

[0033] The photovoltaic glass detection device provided in the embodiment of the present application is exemplified in FIG1 , which is a schematic diagram of the structure of the photovoltaic glass detection device provided in the embodiment of the present application. The photovoltaic glass detection device of the present application can be used for the preparation of double-glass photovoltaic modules. When preparing double-glass photovoltaic modules, it can facilitate operators to identify whether the incoming photovoltaic glass has openings, so as to prepare photovoltaic glass for the light-receiving surface and photovoltaic glass for the backlight surface.

[0034] In order to more clearly illustrate the structure of the photovoltaic glass detection device, the photovoltaic glass detection device will be introduced below in conjunction with the accompanying drawings. For example, please refer to Figure 1, which is a schematic diagram of the structure of the photovoltaic glass detection device provided in an embodiment of the present application.

[0035] A photovoltaic glass detection device 10 includes a machine 100, a transmission mechanism, a detection mechanism and a control mechanism. The transmission mechanism is installed on the machine 100 for receiving and transmitting photovoltaic glass 20, and the transmission mechanism can realize the positioning of photovoltaic glass 20 at a preset position on the transmission surface. The detection mechanism is a reflector-type photoelectric sensor. The detection mechanism is installed on the machine 100 to detect whether the photovoltaic glass 20 at the preset position has an opening 21. The control mechanism is electrically connected to the detection mechanism to obtain a detection signal of the detection mechanism, and the detection signal includes a strong pulse signal when the photovoltaic glass 20 has an opening 21, and a strong pulse signal and a weak pulse signal when the photovoltaic glass 20 does not have an opening 21. When the control mechanism obtains the strong pulse signal of the detection mechanism, it indicates that the incoming photovoltaic glass 20 is a photovoltaic glass 20 with a hole for the backlight surface; when the control mechanism obtains the strong pulse signal and the weak pulse signal of the detection mechanism, it indicates that the incoming photovoltaic glass 20 is a photovoltaic glass 20 without a hole for the light-receiving surface.

[0036] In the present application, when the photovoltaic glass 20 has an opening 21, the light emitted by the transmitter 310 of the detection mechanism needs to be reflected back by the reflector and received by the receiver, and a strong pulse signal will be generated at this time. When the photovoltaic glass 20 does not have an opening 21, part of the light emitted by the transmitter 310 of the detection mechanism is reflected back by the reflector and received by the receiver, and a strong pulse signal will be generated at this time; since the light transmittance of the glass is not 100%, even for transparent glass, its maximum light transmittance is about 95%, therefore, another part of the light emitted by the transmitter 310 of the detection mechanism is directly reflected back after passing through the photovoltaic glass 20 and received by the receiver, and a weak pulse signal will be generated at this time, and the generation time of the weak pulse signal is less than that of the strong pulse signal; the control mechanism determines whether the photovoltaic glass 20 has an opening 21 according to the single strong pulse signal detected by the detection mechanism, or the double signal of the strong pulse signal and the weak pulse signal. Conversely, when the control mechanism obtains a single strong pulse signal detected by the detection mechanism, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 with an opening 21. When the control mechanism obtains a double signal of a strong pulse signal and a weak pulse signal, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 without an opening 21. The control mechanism controls the transmission mechanism to shut down or continue working according to the judgment result, and can also remind the operator to select the incoming material.

[0037] In some embodiments, the detection mechanism includes a transmitter 310, a receiver, and a reflector. The transmitter 310 and the receiver are installed on the machine and 100 are located on the same side of the transmission surface, and the reflector is installed on the machine 100 and is located on the other side of the transmission surface. During installation, the transmitter 310 and the receiver are installed in the same device, and the photoelectric control function is completed by using the reflection principle.

[0038] In some embodiments, as shown in FIG. 1 , the transmission mechanism includes a plurality of transmission wheels 200. The plurality of transmission wheels 200 are mounted on the machine 100, the axes of the plurality of transmission wheels 200 are located at the same horizontal height, the top surfaces of the plurality of transmission wheels 200 constitute the transmission surface, and the transmission wheels 200 rotate in the same direction. The direction in which the photovoltaic glass 20 moves forward after the rotation of the transmission wheels 200 is the transmission direction.

[0039] In some embodiments, please refer to Fig. 1, a first supporting bar 110 and a second supporting bar 120 are disposed opposite to each other on the machine 100. A plurality of transmission wheels 200 are rotatably connected to the first supporting bar 110 and the second supporting bar 120 respectively.

[0040] In some embodiments, as shown in FIG. 1 , a support frame 130 is further connected to the machine 100. The support frame 130 is disposed between the first support bar 110 and the second support bar 120. The support frame 130 is used to assist in supporting the photovoltaic glass 20 on the transmission wheel 200. Preferably, the top surface of the support frame 130 is flush with the top surface of the transmission wheel 200, and the top surface of the support frame 130 is flush with the top surface of the transmission wheel 200, and together they constitute the above-mentioned transmission surface.

[0041] In some embodiments, there are multiple support frames 130 . The multiple support frames 130 are distributed at intervals. The function of the support frames 130 is to support the photovoltaic glass 20 and stabilize the photovoltaic glass 20 .

[0042] In some embodiments, the support frame 130 is in a long strip structure and extends along the transmission direction of the photovoltaic glass 20 .

[0043] In some embodiments, as shown in FIG1 , the detection mechanism further includes a detection bracket 320. The detection bracket 320 is disposed above the machine 100, and the transmitter 310 and the receiver are mounted on the detection bracket 320. In FIG1 , the transmitter 310 is mounted on the detection bracket 320, and the receiver is not shown.

[0044] In some embodiments, the detection bracket 320 is in a grid shape.

[0045] In some of the embodiments, when the photovoltaic glass is the photovoltaic glass 20 on the backlight side, the photovoltaic glass 20 of the detection mechanism is positioned to correspond to the position of one of the openings 21 behind the transmission mechanism.

[0046] In some embodiments, when the photovoltaic glass is a photovoltaic glass 20 with a backlight surface, the number of detection mechanisms is multiple, and the multiple detection mechanisms correspond one-to-one to the positions of the multiple openings 21 of the photovoltaic glass 20 positioned behind the transmission mechanism. The present application can improve detection accuracy and avoid missed detection or false detection by setting multiple detection mechanisms to detect different openings 21 respectively.

[0047] In some embodiments, the photovoltaic glass detection device 10 also includes a display mechanism. The display mechanism can be a display screen, a touch screen, etc. The display mechanism can also perform human-computer interaction. The display mechanism is not shown in the accompanying drawings. When the control mechanism obtains a strong pulse signal from the detection mechanism, it indicates that the incoming photovoltaic glass 20 is a photovoltaic glass 20 with holes for the backlight surface, and the display mechanism displays that the incoming photovoltaic glass 20 is a photovoltaic glass 20 for the backlight surface; when the control mechanism obtains a strong pulse signal and a weak pulse signal from the detection mechanism, it indicates that the incoming photovoltaic glass 20 is a photovoltaic glass 20 without holes for the light-receiving surface, and the display mechanism displays that the incoming photovoltaic glass 20 is a photovoltaic glass 20 for the light-receiving surface. The operator can perform corresponding operations according to the results displayed by the display mechanism.

[0048] In some embodiments, the photovoltaic glass detection device 10 further includes an alarm mechanism. The alarm mechanism is electrically connected to the control mechanism, and the alarm mechanism can give an alarm according to the detection signal of the detection mechanism obtained by the control mechanism. The alarm mechanism is not shown in FIG1 .

[0049] In some embodiments, the alarm mechanism includes one or more of a signal light and a buzzer. The alarm mechanism visually and audibly reminds the operator through the flashing of the signal light and the sound of the buzzer.

[0050] In some embodiments, the control mechanism is electrically connected to the transmission mechanism, the detection mechanism, and the alarm mechanism. The control mechanism is used to perform signal transmission and electrical control between the transmission mechanism, the detection mechanism, and the alarm mechanism.

[0051] In some of the embodiments, the control mechanism is a PLC programmable controller.

[0052] In some embodiments, the photovoltaic glass detection device 10 further includes a correction mechanism installed on the machine 100. The correction mechanism is used to correct the position of the photovoltaic glass 20 on the transmission mechanism, so that when the photovoltaic glass 20 is the back photovoltaic glass 20, the position of one of the openings 21 on the back photovoltaic glass 20 corresponds to the detection mechanism.

[0053] In some of the embodiments, the correction mechanism includes a plurality of correction baffles and a correction drive component. The correction baffle is movably connected to the machine, and the correction drive component is electrically connected to the control mechanism. The correction drive component is connected to the correction baffle and drives the correction baffle to move to a preset position to correct the position of the photovoltaic glass 20. Before correction, the correction baffle is away from the transmission surface. When the photovoltaic glass 20 reaches the preset position, the correction drive component drives the plurality of correction baffles to move toward the transmission surface to a predetermined position to correct the position of the photovoltaic glass 20, ensuring that when the corrected photovoltaic glass 20 is the photovoltaic glass 20 on the backlight side, the position of the opening 21 on the photovoltaic glass 20 is aligned with the detection mechanism.

[0054] In the present application, when the photovoltaic glass detection device 10 is working, the control mechanism controls the transmission wheel 200 of the transmission mechanism to work, and after the photovoltaic glass 20 is transmitted to the predetermined position, the transmission wheel 200 stops rotating. The control mechanism controls the correction driving component to drive multiple correction baffles to move to the predetermined position in the direction of the transmission surface. The correction baffles are in the predetermined position to realize the correction of the position of the photovoltaic glass 20, ensuring that when the corrected photovoltaic glass 20 is the photovoltaic glass 20 on the backlight surface, the position of the opening 21 on the photovoltaic glass 20 is aligned with the detection mechanism. The control mechanism controls the transmitter 310 of the detection mechanism to work, and the transmitter 310 emits a detection light. When the control mechanism obtains a double signal of a strong pulse signal and a weak pulse signal received by the receiver, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 without an opening 21, and the signal light of the alarm mechanism does not work, prompting the operator that the photovoltaic glass 20 is a photovoltaic glass 20 used as a light-receiving surface without an opening 21. When the control mechanism obtains a single strong pulse signal received by the receiver, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 with an opening 21, and the signal light of the alarm mechanism works, reminding the operator that the photovoltaic glass 20 is a photovoltaic glass 20 used as a backlight surface with an opening 21. When the signal light of the alarm mechanism does not work, the control mechanism can continue to control the transmission mechanism to transmit the photovoltaic glass 20 to the next station for use in the next process.

[0055] The signal light indication content can be set as needed. For example, when the control mechanism obtains a double signal of a strong pulse signal and a weak pulse signal received by the receiver, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 with an opening 21, and the signal light of the alarm mechanism works, reminding the operator that the photovoltaic glass 20 is a photovoltaic glass 20 with an opening 21 used as a backlight surface. When the control mechanism obtains a single strong pulse signal received by the receiver, it indicates that the photovoltaic glass 20 is a photovoltaic glass 20 without an opening 21, and the signal light of the alarm mechanism does not work, reminding the operator that the photovoltaic glass 20 is a photovoltaic glass 20 without an opening 21 used as a light-receiving surface.

[0056] The size of the opening 21 on the photovoltaic glass 20 is 12 mm in diameter. As an essential material for the backlight surface of the double-glass photovoltaic module, the size of the photovoltaic glass 20 on the backlight surface is relatively uniform. The size of the photovoltaic glass 20 can be changed according to actual needs and version.

[0057] The detection object of the photovoltaic glass detection device 10 of the utility model is the photovoltaic glass 20 with a backlight surface having an opening 21 or the photovoltaic glass 20 with a non-porous light-receiving surface. The size of the photovoltaic glass 20 with a backlight surface having an opening 21 is consistent with that of the photovoltaic glass 20 with a non-porous light-receiving surface. For example, the size of the photovoltaic glass 20 with a backlight surface having an opening 21 and the photovoltaic glass 20 with a non-porous light-receiving surface is 2459mm in length × 1128mm in width. It is not difficult to understand that the size of the photovoltaic glass 20 with a backlight surface having an opening 21 and the photovoltaic glass 20 with a non-porous light-receiving surface can be selected according to the actual module model produced.

[0058] To sum up, when the photovoltaic glass detection device 10 of the utility model is used in the production of photovoltaic modules, it can realize the detection of photovoltaic glass 20 with holes for the backlight side or photovoltaic glass 20 without holes for the light-receiving side, and timely remind the operating personnel of the type of incoming materials, so as to facilitate the operating personnel to distinguish and select the incoming photovoltaic glass 20 as the photovoltaic glass 20 for the backlight side or the photovoltaic glass 20 for the light-receiving side, avoid the wrong selection of photovoltaic glass 20 due to operator misoperation, reduce product defective rate, realize standardized and convenient detection operation, and make the operation convenient and more efficient.

[0059] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model.
