Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic manufacturing, in particular to a fool-proof device for glass feeding in photovoltaic manufacturing. Background Art
[0002] As global temperatures rise, people's demand for clean energy is rapidly increasing. Photovoltaics are adaptable to various regions and environments and have relatively low electricity costs, which has led to a sharp increase in demand for photovoltaic products. This has put tremendous pressure on photovoltaic production capacity and yield rate. Incorrect use of glass in the manufacturing process of photovoltaic products is an important factor affecting the yield rate.
[0003] Currently, photovoltaic products are available in both single-glass and double-glass modules, in addition to different sizes. These modules differ not only in the number of glass panes, thickness, and weight, but also in the front and back glass panes, making the design more complex. Photovoltaic workshops often produce multiple products simultaneously, which can easily lead to glass loading errors and negatively impact product yields. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a photovoltaic manufacturing glass feeding error-proofing device, which can effectively reduce the glass feeding error rate in the photovoltaic manufacturing process and improve the yield rate.
[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0006] A photovoltaic manufacturing glass loading fool-proofing device includes a turntable, a weighing assembly, a flow mechanism, a correction mechanism and a PLC controller. The weighing assembly is arranged on the top of the turntable and is used to obtain the weight information of the glass. The PLC controller is electrically connected to the weighing assembly and is used to determine whether the weight of the glass meets the set weight control range based on the weight information. The flow mechanism is arranged on the top of the weighing assembly and is electrically connected to the PLC controller. It is used to transfer the glass that meets the set weight control range to the next process according to the instructions of the PLC controller. The correction mechanism is arranged on the flow mechanism and is electrically connected to the PLC controller. It is used to control the glass loaded from the loading area to the same set position according to the instructions of the PLC controller.
[0007] Furthermore, the weighing assembly includes a weighing frame, a weighing sensor and a data processor. The weighing frame is arranged on the top of the turntable. The weighing sensor and the data processor are arranged on the weighing frame. The weighing sensor is electrically connected to the data processor and is used to convert the glass weight information into an electrical signal and transmit it to the data processor. The data processor is electrically connected to the PLC controller and is used to process the received signal to obtain weight information and transmit it to the PLC controller.
[0008] Further, the photoelectric sensor is arranged on the weighing assembly and located directly below the opening of the glass after the correction by the correction mechanism, and the photoelectric sensor is electrically connected with the PLC controller, and whether the light emitted upward by the photoelectric sensor is blocked is used to determine the front glass or the back glass.
[0009] Further, the photoelectric sensor has three, which are consistent with the number of the openings of the glass and one-to-one correspondence.
[0010] Further, the alarm is electrically connected with the PLC controller and used to give an alarm when the glass does not meet the requirements.
[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0012] 1、 the utility model discloses a weighing assembly and the setting of PLC controller can effectively distinguish the glass material of single (block) glass and double (block) glass assembly, avoid the feeding error, thereby effectively improving the finished product yield.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.
[0019] Embodiment 1:
[0020] As Figures 1-2 shown, the embodiment provides a foolproof device for feeding photovoltaic manufacturing glass, which comprises a flow table 1, a weighing assembly, a centering mechanism 3, a flow mechanism 4 and a PLC controller (not shown in the figure). The weighing assembly is arranged on the top of the flow table 1 and is used to obtain the weight information of the glass. The PLC controller is electrically connected with the weighing assembly and is used to determine whether the weight of the glass meets the set weight control range according to the weight information. The flow mechanism 4 is arranged on the top of the weighing assembly and is electrically connected with the PLC controller, and is used to flow the glass meeting the set weight control range to the next process according to the instruction of the PLC controller. The centering mechanism 3 is arranged on the flow mechanism 4 and is electrically connected with the PLC controller, and is used to control the glass fed from the feeding area to be at the same set position according to the instruction of the PLC controller.
[0021] Specifically, the weighing assembly comprises a weighing rack 2, a weighing sensor (not shown in the figure) and a data processor (not shown in the figure). The weighing rack 2 is arranged on the top of the flow table 1. The weighing sensor and the data processor are arranged on the weighing rack 2. The weighing sensor is electrically connected with the data processor, and is used to convert the weight information of the glass into an electrical signal and transmit it to the data processor. The data processor is electrically connected with the PLC controller, and is used to process the received signal to obtain the weight information and transmit it to the PLC controller.
[0022] Specifically, it further comprises an alarm 6, which is electrically connected with the PLC controller and is used to issue an alarm when the fed glass does not meet the requirements.
[0023] The operation of the foolproof device for distinguishing single / double glass assembly glass of the embodiment is as follows:
[0024] The glass 8 is grabbed from the feeding area to the flow table 1 by the mechanical arm 5. The glass is positioned by the centering mechanism 3, so that the glass is controlled at the set position. After the centering positioning, it can be ensured that each glass is fed to the same position. Then the weight information of the glass is obtained by the weighing assembly and transmitted to the PLC controller. The PLC controller controls the single / double glass assembly glass according to the set weight control range (single / double glass assembly glass has a large difference in weight due to different thicknesses of the same specification). When the weight information does not meet the set weight control range, the PLC controller triggers the alarm 6 and stops. At this time, the glass meeting the requirements is replaced to eliminate the alarm and the equipment continues to operate. If the weight of the glass meets the set weight control range, the flow mechanism 4 will flow the glass to the next process.
[0025] Embodiment 2:
[0026] As Figures 3-4As shown, the embodiment provides a foolproof device for feeding photovoltaic manufacturing glass. The difference between the embodiment and embodiment 1 is that the weighing assembly is further provided with photoelectric sensors 7. The number of photoelectric sensors can be set according to the number of glass holes. The embodiment takes three photoelectric sensors as an example. The three photoelectric sensors are located directly below the three holes 801 of the glass 8 after the glass is corrected by the correction mechanism 3. The photoelectric sensors 7 are electrically connected with the PLC controller. Whether the light emitted upward by the photoelectric sensors 7 is blocked or not determines whether the glass is a front glass or a back glass.
[0027] The operation of the foolproof device for distinguishing front / back glass of the embodiment is as follows:
[0028] The glass 8 is grabbed from the feeding area to the flow table 1 by the mechanical arm 5. The glass is positioned by the correction mechanism 3 so as to control the glass in the set position. After the correction and positioning, it is ensured that each glass is fed to the same position. (The double glass assembly requires that the back glass has three holes in the middle part.) After the correction is completed, the photoelectric sensors 7 emit infrared light upward. If there is a blocking signal, it means that the glass is a front glass. If there is no blocking, it means that the infrared light can pass through the glass hole, which is a back glass. According to the setting of the PLC controller, the type of front / back glass is controlled. When the type of glass does not meet the set requirements, the PLC controller triggers the alarm 6 and stops. At this time, the glass meeting the requirements is replaced to eliminate the alarm and the equipment continues to operate. If the type of glass meets the requirements, the flow mechanism 4 will flow the glass to the next process.
[0029] The above is only the preferred embodiment of the utility model patent, but the protection scope of the utility model patent is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model patent concept of the utility model patent within the scope disclosed by the utility model patent, which belongs to the protection scope of the utility model patent.
