Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic panel detection device. Background Art

[0002] In photovoltaic modules, photovoltaic panels include front panels and back panels. Generally, glass is used for the front panel or the back panel. The main function of glass is to transmit sunlight and bear the mechanical load of the photovoltaic module itself, while improving the durability of the photovoltaic module. During the production of traditional photovoltaic modules such as double-glass modules, the front panel, front film, battery body, back film and back panel are laid out and then synthesized through a series of processes such as laminators and frame assemblies. When the front panel and the back panel are used in the production of photovoltaic modules, they are generally stored at the same time. In this way, it is easy for operators to take the wrong materials during the loading process, resulting in the problem of mixing the front panel and the back panel.

[0003] Traditional technology adds a CCD (Charge coupled Device) camera to the rear panel loading platform assembly line, and uses visual recognition to identify the glaze color and chamfer direction on the rear panel to identify whether the front panel and the rear panel are mixed, placed upside down or wrong, and trigger an alarm to manually handle the abnormality. The CCD camera can only identify glass plates with glaze colors, but cannot identify glass plates without glaze colors used in gap film components. The front and rear panels of the gap film only differ in the reserved holes, that is, the front panel has no holes, and the rear panel has reserved bus bar lead-out holes, such as three holes. Therefore, when producing gap film components, once the mixing problem between the front and rear panels occurs, it is easy to cause equipment shutdown, batch production of defective products, lead to rework, waste of manpower, and reduce production efficiency.

[0030] The embodiment of the present application provides a photovoltaic panel detection device 10 to solve the problem that the CCD camera in the prior art cannot detect whether the incoming photovoltaic panel is a front panel or a back panel in the production of double-glass modules. The photovoltaic panel detection device 0 will be described below in conjunction with the accompanying drawings.

[0031] The photovoltaic panel detection device 10 provided in the embodiment of the present application is exemplified as shown in FIG1 , which is a schematic diagram of the structure of the photovoltaic panel detection device 10 provided in the embodiment of the present application. The photovoltaic panel detection device 10 of the present application can be used to detect and identify the front panel and the back panel of the double-glass module to avoid mixing the front panel and the back panel.

[0032] In order to more clearly illustrate the structure of the photovoltaic panel detection device 10, the photovoltaic panel detection device 10 will be introduced in conjunction with the accompanying drawings. For example, please refer to FIG1, a photovoltaic panel detection device 10 includes a machine 100, a transmission mechanism 200, a vacuum generating mechanism 300 and a control mechanism (not shown). The transmission mechanism 200 is installed on the machine 100, and a part of the area on the transmission mechanism 200 can be preset as a vacuum adsorption station. The transmission mechanism 200 is used to receive and transmit the photovoltaic panel to the vacuum adsorption station to facilitate the operation of the vacuum generating mechanism 300. The vacuum generating mechanism 300 is installed on the machine 100. The vacuum generating mechanism 300 is used to vacuum adsorb the photovoltaic panel located at the vacuum adsorption station. When the photovoltaic panel is a back panel, at least one opening position on the back panel is located within the adsorption surface of the vacuum generating mechanism 300. The control mechanism is electrically connected to the vacuum generating mechanism 300, and is used to receive a vacuum suction signal or a vacuum breaking signal of the vacuum generating mechanism 300 for vacuum adsorption.

[0033] In the present application, the front panel and the back panel of the same model of photovoltaic modules have the same size. Therefore, when the transmission mechanism 200 is transmitting, setting a fixed transmission path for the transmission mechanism 200 can ensure that all photovoltaic panels (front panels or back panels) are transmitted to the vacuum adsorption station. Since the position of the openings on the back panel is fixed, when the photovoltaic panel is the back panel, after the back panel is transmitted to the vacuum adsorption station, at least one of the openings on the back panel is located within the adsorption surface of the vacuum generating mechanism 300. Preferably, one of the openings on the back panel is located within the adsorption surface of the vacuum generating mechanism 300.

[0034] When the photovoltaic panel detection device 10 of the present application is in use, when the vacuum generating mechanism 300 cannot perform vacuum adsorption normally, a vacuum breaking signal is generated, indicating that the photovoltaic panel is a rear panel with holes. When the vacuum generating mechanism 300 performs vacuum adsorption normally, a vacuum suction signal is generated, indicating that the photovoltaic panel is a front panel without holes, thereby detecting the type of the photovoltaic panel.

[0035] When the photovoltaic panel detection device 10 is detecting, the transmission mechanism 200 receives the loaded photovoltaic panel (front panel or back panel), and the photovoltaic panel is transmitted to the set vacuum adsorption station through the transmission mechanism 200. The vacuum generating mechanism 300 moves to the adsorption surface close to the photovoltaic panel, and the control mechanism controls the vacuum generating mechanism 300 to work. When the loaded photovoltaic panel is the front panel, since the front panel has no holes, the vacuum generating mechanism 300 can normally vacuum adsorb and generate a vacuum absorption signal. When the loaded photovoltaic panel is the back panel, since the back panel has holes, the vacuum generating mechanism 300 corresponds to one of the opening positions, so the vacuum generating mechanism 300 cannot normally vacuum adsorb and generate a vacuum breaking signal. The control mechanism receives the vacuum absorption signal or vacuum breaking signal of the vacuum generating mechanism 300, and performs corresponding actions according to the vacuum absorption signal or vacuum breaking signal, such as reminding the operator to handle or controlling the transmission mechanism 200 to continue transmission, shut down, etc.

[0036] In some embodiments, the transmission mechanism 200 includes a plurality of transmission wheels. The plurality of transmission wheels are mounted on the machine 100, the axes of the plurality of transmission wheels are located in the same horizontal plane, the rotation directions of the transmission wheels are the same, and the top surfaces of the plurality of transmission wheels constitute a transmission surface. The direction in which the photovoltaic panel moves forward after the transmission wheels rotate is the transmission direction. FIG1 only shows the support part used for transmission, and the transmission wheels and the transmission belt are not shown.

[0037] In some of the embodiments, the vacuum generating mechanism 300 is located below the transmission surface of the transmission mechanism 200 . Such a configuration can save space on the machine 100 and facilitate the transmission of the photovoltaic panels by the transmission mechanism 200 .

[0038] In some embodiments, there are multiple vacuum generating mechanisms 300, and the number of vacuum generating mechanisms 300 is consistent with the number of openings on the back panel. For example, there are three openings on the back panel, and three vacuum generating mechanisms 300 are provided. The positions of the three vacuum generating mechanisms 300 can correspond to the three opening positions on the back panel at the vacuum adsorption station, respectively. The purpose of providing multiple vacuum generating mechanisms 300 is to maximize the detection accuracy and avoid misjudgment problems.

[0039] In some embodiments, the photovoltaic panel detection device 10 further includes a correction mechanism 400 installed on the machine 100. The correction mechanism 400 is used to limit at least one side of the photovoltaic panel on the transmission mechanism 200 to correct the position of the photovoltaic panel, so that when the photovoltaic panel is a back panel, one of the openings on the back panel is accurately located within the adsorption surface of the vacuum generating mechanism 300. Preferably, the correction mechanism 400 is used to limit both sides of the photovoltaic panel on the transmission mechanism 200 to correct the position of the photovoltaic panel.

[0040] In the present application, after the transmission mechanism 200 transmits the photovoltaic panel according to the predetermined transmission path, the position of the photovoltaic panel is basically consistent, but there is also a phenomenon that the position of a small number of photovoltaic panels is slightly offset. Therefore, the precise position of the photovoltaic panel can be achieved by the correction mechanism 400. For the front panel, the vacuum generating mechanism 300 can generate a vacuum suction signal at any position, and for the back panel, the correction mechanism 400 is required to ensure that the opening position is accurately located within the adsorption surface of the vacuum generating mechanism 300. Therefore, the present application sets the correction mechanism 400 to achieve that all photovoltaic panels are transmitted to the predetermined vacuum adsorption station, ensuring that the position of each photovoltaic panel is correct and accurate, avoiding misjudgment due to the position offset of the photovoltaic panel, and improving the detection accuracy.

[0041] In some embodiments, the correction mechanism 400 includes a correction rail 410, a correction slider 420, a correction roller 430 and a correction driving component 440. The correction rail 410 is installed on the machine 100. The correction slider 420 is slidably connected to the correction rail 410. The correction driving component 440 is connected to the correction slider 420 to drive the correction slider 420 to move in a direction perpendicular to the transmission direction. The correction roller 430 can be rotatably connected to the correction slider 420 and act on the side of the photovoltaic panel on the transmission mechanism 200 to correct the position of the photovoltaic panel. In the present application, before correction, the correction slider 420 and the correction roller 430 can be slightly away from the transmission surface. After loading, when the photovoltaic panel is located on the transmission surface and moves to the vacuum adsorption station, the correction drive component 440 drives the correction slider 420 to move toward the transmission surface, and the correction slider 420 drives the correction roller 430 to gradually contact the side of the photovoltaic panel. When the correction slider 420 moves to the predetermined position, the correction roller 430 synchronously completes the correction of the photovoltaic panel, so that the photovoltaic panel is located at the precise position of the vacuum adsorption station. Setting the correction roller 430 can reduce its contact area with the photovoltaic panel and reduce stress. At the same time, during the correction process, if the photovoltaic panel has a certain displacement along the transmission direction, the correction roller 430 and the photovoltaic panel are in rolling connection, which can reduce the friction and stress between the photovoltaic panel and the correction roller 430.

[0042] In some embodiments, the alignment mechanism 400 further includes a connecting rod 450. There are multiple alignment rollers 430, which can rotate on the connecting rod 450 and are installed on the alignment slider 420 through the connecting rod 450. The multiple alignment rollers 430 on the connecting rod 450 can position and align the photovoltaic panel from different positions.

[0043] In some embodiments, there are multiple correcting mechanisms 400. At least one correcting mechanism 400 is respectively arranged on both sides of the transmission surface of the transmission mechanism 200 along the transmission direction. Multiple correcting mechanisms 400 cooperate with each other to correct the position of the photovoltaic panel from both sides of the transmission surface, thereby improving the accuracy of the photovoltaic panel in the vacuum adsorption station.

[0044] Alternatively, in some embodiments, as shown in FIG. 1 , the correction slide rail 410 extends in a direction perpendicular to the transmission direction, and the two ends of the correction slide rail 410 are respectively provided with a correction slider 420, a correction roller 430 and a correction drive component 440. When the correction mechanism 400 also includes a connecting rod 450, the two ends of the correction slide rail 410 are respectively provided with a connecting rod 450. The correction rollers 430 at both ends of the correction slide rail 410 act on the sides of the photovoltaic panel on the transmission mechanism 200 to correct the position of the photovoltaic panel. In addition, the two correction slides 420 can also be driven by a correction drive component 440. The present application can simplify the device structure and reduce the device cost by setting two correction slides 420 to share a correction slide rail 410 and a correction drive component 440 to drive the two correction slides 420.

[0045] In some embodiments, the vacuum generating mechanism 300 includes a vacuum suction cup 310 and a suction cup driving component 320. The vacuum suction cup 310 is movably connected to the machine 100. The suction cup driving component 320 is connected to the vacuum suction cup 310 to drive the vacuum suction cup 310 to move up and down in the vertical direction. The vacuum suction cup 310 can be connected to an external vacuum device to generate negative pressure for vacuum adsorption.

[0046] In some embodiments, the photovoltaic panel detection device 10 also includes an alarm mechanism. The alarm mechanism is electrically connected to the control mechanism, and the alarm mechanism is used to alarm according to the vacuum suction signal or vacuum breaking signal received by the control mechanism from the vacuum generating mechanism 300. The alarm mechanism is not shown in FIG1. ​​For example, after loading, when the vacuum generating mechanism 300 cannot vacuum absorb normally and generates a vacuum breaking signal, it indicates that the photovoltaic panel is a back panel with holes. At this time, the alarm mechanism alarms. When the vacuum generating mechanism 300 vacuum absorbs normally and generates a vacuum suction signal, it indicates that the photovoltaic panel is a front panel without holes. At this time, the alarm mechanism does not alarm. On the contrary, it can also be set that when the vacuum generating mechanism 300 cannot vacuum absorb normally and generates a vacuum breaking signal, it indicates that the photovoltaic panel is a back panel with holes. At this time, the alarm mechanism does not alarm. When the vacuum generating mechanism 300 vacuum absorbs normally and generates a vacuum suction signal, it indicates that the photovoltaic panel is a front panel without holes. At this time, the alarm mechanism alarms.

[0047] 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.

[0048] In some embodiments, the control mechanism is a PLC programmable controller. The control mechanism is not shown in the drawings. The control mechanism can be programmed accordingly according to actual production requirements to achieve control actions corresponding to the detection results.

[0049] In some embodiments, preferably, the transmission mechanism 200 is also electrically connected to the control mechanism. After obtaining the signal from the detection mechanism, the control mechanism can make corresponding control actions on the transmission mechanism 200, such as controlling the transmission mechanism 200 to continue transmitting the photovoltaic panel or shut down.

[0050] In some embodiments, the photovoltaic panel detection device 10 further includes a display mechanism. The display mechanism may be a display screen, etc. The display screen is electrically connected to the control mechanism. The display screen is used to display the detection result. When the photovoltaic panel detection device 10 of the present application is in use, when the vacuum generating mechanism 300 cannot vacuum adsorb normally, a vacuum breaking signal is generated, and at this time, the display screen displays that the photovoltaic panel is a back panel with holes. When the vacuum generating mechanism 300 vacuum adsorbs normally, a vacuum suction signal is generated, and at this time, the display screen displays that the photovoltaic panel is a front panel without holes.

[0051] In some of the embodiments, the display screen may be a touch screen, and the display screen enables human-computer interaction.

[0052] In some of the embodiments, the photovoltaic panel detection device 10 may be arranged on a photovoltaic module production line, and the specific location may be set according to actual needs.

[0053] Another embodiment of the present application also provides a photovoltaic module production device.

[0054] The photovoltaic module production equipment includes the photovoltaic panel detection device 10. The photovoltaic panel detection device 10 is used to detect whether the incoming photovoltaic panel is a rear panel with holes or a front panel without holes on the photovoltaic module production line, and to promptly remind the operator.

[0055] To sum up, when the above-mentioned photovoltaic panel detection device 10 is used in the production of photovoltaic modules, it can detect whether the incoming photovoltaic panel is a back panel with holes or a front panel without holes, and promptly remind the operator of the type of incoming photovoltaic panel, which is convenient for the operator to distinguish and select, avoid operator misoperation, prevent mixing of materials, avoid equipment downtime, reduce or avoid batch production of defective products, better realize production line automation, improve the yield of photovoltaic modules, improve production efficiency, and reduce labor costs.

[0056] 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.

[0057] 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.

[0058] 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. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
