Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic manufacturing, and in particular to a photovoltaic production line and a control method capable of preventing glass from being scratched. Background Art

[0002] In recent years, the demand for high power and low cost has been booming. Cost reduction and efficiency improvement are the top priorities of the photovoltaic industry. The efficiency improvement of photovoltaic materials on components has become the mainstream of the market. For example, the double-layer coated photovoltaic glass currently being developed has an increase of 1.5-3W compared to the original single-layer coated glass, and has been favored by many photovoltaic companies.

[0003] However, due to the relatively sparse apertures and soft hardness of double-layer coatings, friction between the glass surface and the assembly line during the manufacturing process can cause scratches on the glass and damage to the coating. Currently, most industries rely on manual wiping, which still leaves marks on the glass and creates the risk of customer complaints. Therefore, existing assembly lines are no longer sufficient for mass production of double-layer coated glass.

[0004] Therefore, how to efficiently solve this technical problem is one of the focuses of work for those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide a photovoltaic assembly line and control method that can prevent glass scratches. The lifting assembly line is used to reduce the friction generated during the component circulation process, solve the defects such as coating damage, scratches and marks on double-layer coated glass, improve the yield rate, and reduce production products.

[0006] To solve the above technical problems, an embodiment of the present invention provides a photovoltaic production line control method capable of preventing glass scratches, comprising:

[0007] S1, after detecting the output component of the first station, controlling the component to transfer the tooling to receive the component;

[0008] S2, the component transfer tool receives and lifts the component, transports the component to the front end of the second station, and sends a component lifting completion signal to the second station;

[0009] S3, after receiving the lifting completion signal, the second station component takes away the component lifted by the component transfer tooling and transmits a tooling output component reception completion signal to the component;

[0010] S4, after receiving the component receiving completion signal, the component transport tool returns to the output end of the first station to wait.

[0011] In addition, an embodiment of the present application also provides a photovoltaic assembly line that can prevent glass scratches, which adopts the photovoltaic assembly line control method that can prevent glass scratches as described above, including a component transfer tooling with a lifting mechanism arranged between the first station and the second station, which is used to lift and transport the components output from the first station to the second station and then return to the end of the first station.

[0012] It also includes a transport line, a return line and a controller that are arranged in parallel and interconnected between the first station and the second station, wherein the component transfer tooling receives the component arrival signal output from the first station sent by the controller at the front end of the transport line, receives the component output from the first station and fixes it through the lifting mechanism, and then lifts the component to the end of the transport line through the transport line. The controller sends a component lifting completion signal to the second station through the controller, and the controller controls the second station to receive the component and outputs a component reception completion signal to the component transfer tooling. The controller controls the component transfer tooling to transfer from the transport line to the return line and return to the end of the first station, or controls the component transfer tooling to transfer from the return line to the transport line after receiving the component arrival signal.

[0013] Wherein, it also includes an epoxy resin layer arranged on the top of the lifting mechanism.

[0014] Among them, it also includes a transfer line arranged between the transport line and the return line. The transfer line is a rectangular staggered diagonal double-layer structure line, which is used to transfer the component transfer tooling between the transport line and the return line by lifting.

[0015] Wherein, the component transfer tooling is an I-shaped component transfer tooling or a U-shaped component transfer tooling.

[0016] It also includes an assembly line guardrail arranged parallel to the transport assembly line and a photoelectric sensing device arranged on the assembly line guardrail facing the transport assembly line, and the photoelectric sensing device is used to detect the position information of the component transport tooling.

[0017] Wherein, the spacing between adjacent photoelectric sensing devices is equal to the length of the component transfer tooling.

[0018] Wherein, a base plate is provided at the bottom of the component transfer tooling for connecting to the guide rails of the transport line or the return line.

[0019] Among them, the controller includes a model signal collector, a PLC and a pneumatic control valve. After the model signal collector generates a control scheme based on the current model of the component, the PLC is used to implement parameter control of the transport assembly line, the return assembly line and the lifting mechanism.

[0020] The photovoltaic production line and control method thereof that can prevent glass from being scratched provided by the embodiments of the present invention have the following advantages over the prior art:

[0021] The photovoltaic assembly line and control method thereof capable of preventing glass from being scratched, after detecting that the first station outputs a component, controls the component transfer tooling to receive the component, then lifts the component and transports the component to the front end of the second station, and sends a component lifting completion signal to the second station. After the second station component receives the lifting completion signal, it takes away the component lifted by the component transfer tooling, and outputs a component reception completion signal to the component transfer tooling; after the component transfer tooling receives the component reception completion signal, it returns to the output end of the first station to wait. Since the component is in a lifting state between the first station and the second station and is in a relative stationed state with the component transfer tooling, it will not move relative to other components, thereby reducing the possibility of component scratches, solving the problems of coating damage, scratches and marks on double-layer coated glass, improving the product yield, and reducing component costs.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Please refer to Figure 1-2 , Figure 1 A schematic flow chart of steps of an embodiment of a photovoltaic production line control method capable of preventing glass scratches provided by an embodiment of the present invention; Figure 2 A schematic structural diagram of an embodiment of a photovoltaic assembly line capable of preventing glass scratches provided by an embodiment of the present invention.

[0027] In a specific embodiment, the photovoltaic assembly line control method capable of preventing glass scratches includes:

[0028] S1, after detecting the output component of the first station, controlling the component to transfer the tooling to receive the component;

[0029] S2, the component transfer tool receives and lifts the component, transports the component to the front end of the second station, and sends a component lifting completion signal to the second station;

[0030] S3, after receiving the lifting completion signal, the second station component takes away the component lifted by the component transfer tooling and transmits a tooling output component reception completion signal to the component;

[0031] S4, after receiving the component receiving completion signal, the component transport tool returns to the output end of the first station to wait.

[0032] After detecting that the first station outputs the component, the control component transfer tooling receives the component, then lifts the component and transports the component to the front end of the second station, and sends a component lifting completion signal to the second station. After the second station component receives the lifting completion signal, it takes away the component lifted by the component transfer tooling and outputs a component reception completion signal to the component transfer tooling; after the component transfer tooling receives the component reception completion signal, it returns to the output end of the first station and waits. Since the component is in a lifting state between the first station and the second station and is in a relative stationed state with the component transfer tooling, it will not move relative to other components, reducing the possibility of scratches on the component, solving the problems of double-layer coated glass coating damage, scratches and marks, improving product yield, and reducing component costs. The structure is simple. The use of a lifting assembly line reduces the friction generated during the component circulation process, solves the problems of double-layer coated glass coating damage, scratches and marks, improving product yield, and reducing production costs.

[0033] In addition, an embodiment of the present application also provides a photovoltaic assembly line that can prevent glass scratches, which adopts the photovoltaic assembly line control method that can prevent glass scratches as described above, including a component transfer tool 30 with a lifting mechanism 40 arranged between the first station and the second station, which is used to lift and transport the components output from the first station to the second station and then return to the end of the first station.

[0034] Since the photovoltaic assembly line capable of preventing glass from being scratched adopts the photovoltaic assembly line control method capable of preventing glass from being scratched as described above, it has the same beneficial effects, and this application will not elaborate on this.

[0035] Since the component transfer tool 30 is used to move back and forth between the first station and the second station in this application, if there is only one component transfer tool 30, that is, only one component can be transported at the same time between the first station and the second station or only one component transfer tool 30 is used to transport components, then before the current component is completed, the first station will not allow any component 50 to be output, which will greatly reduce the transportation efficiency.

[0036] In order to solve the technical problem of season, in one embodiment, the photovoltaic assembly line that can prevent glass from being scratched also includes a transport assembly line 10, a return assembly line 20 and a controller that are arranged in parallel and interconnected between the first station and the second station, wherein the component transfer tool 30 receives the component arrival signal output from the first station issued by the controller at the front end of the transport assembly line 10, receives the component output from the first station and fixes it through the lifting mechanism 40, and then after the transport assembly line 10 lifts the component to the end of the transport assembly line 10, sends a component lifting completion signal to the second station through the controller, and the controller controls the second station to receive the component and outputs a component reception completion signal to the component transfer tool 30, and the controller controls the component transfer tool 30 to transfer from the transport assembly line 10 to the return assembly line 20 and return to the end of the first station, or controls the component transfer tool 30 to transfer from the return assembly line 20 to the transport assembly line 10 after receiving the component arrival signal.

[0037] By setting up the transport line 10 and the return line 20 and controlling them through the controller, after completing the current component transportation, there is no need to return directly to the first station, but other component transfer tooling 30 can be used to transport the components.

[0038] For example, there is a component transfer tooling 30 on each of the transport line 10 and the return line 20. After the component transfer tooling 30 of the transport line 10 completes the component receiving and transportation, it moves to the second station, and the component transfer tooling 30 of the return line 20 is transferred to the transport line 10 to wait for transportation instructions. The component transfer tooling 30 that completes the transportation will not continue to stay on the transport line 10, but will be transferred to the return line 20 and return to the standby position to wait for the task. There will be no obstruction or waiting. More efficient component transportation can be achieved by setting two or even more component transfer tools 30. Of course, it can also be achieved by improving the efficiency of a single transport tooling.

[0039] The present application includes but is not limited to the above-mentioned structure, and the total number of component transfer tooling 30 is not limited.

[0040] In order to further reduce possible damage to the component 50 caused by the tooling, in one embodiment, the photovoltaic production line capable of preventing glass from being scratched further includes an epoxy resin layer disposed on top of the lifting mechanism 40 .

[0041] This application does not limit the structure of the lifting mechanism 40. Since the component transfer tooling 30 needs to be recycled between the return assembly line 20 and the transport assembly line 10, and if the heights of the return assembly line 20 and the transport assembly line 10 are equal, unless the distance between the return assembly line 20 and the transport assembly line 10 is large enough, the two will cause damage to the components 50 of the adjacent assembly line due to the top being flush.

[0042] Therefore, generally during transportation, the components can be stored through the lifting mechanism 40, but this will take up a large space. Alternatively, the components can be raised through the lifting mechanism 40, which will avoid the components being damaged by collision with adjacent component transfer tooling 30. The corresponding transport line can also be raised or lowered by the amount, so that the distance between the two transport lines can be set shorter, reducing the distance between them and reducing the space occupied.

[0043] In this application, since the component transfer tooling needs to be transferred between the transport assembly line and the return assembly line, there is no limitation on the transfer method. It can be a railway switch transfer method or other methods. However, since the switch method requires occupying a relatively poor space and the weight of the component transfer tooling is relatively low, it can be transferred by moving or other methods, which can improve the transfer efficiency and reduce the occupied space.

[0044] In one embodiment, the photovoltaic assembly line that can prevent glass scratches also includes a transfer assembly line arranged between the transport assembly line and the return assembly line. The transfer assembly line is a rectangular staggered diagonal double-layer structure assembly line, which is used to transfer the component transfer tooling between the transport assembly line and the return assembly line by lifting.

[0045] The present application includes but is not limited to the above-mentioned structure. In addition to using the above-mentioned method, a telescopic device can be set on the component transfer tooling 30. After being transferred to the return assembly line 20, the top drops. Conversely, after being transferred to the transport assembly line 10, the top rises. In this way, the return assembly line 20 and the transport assembly line 10 can be defined as needed, reducing the difficulty of site installation.

[0046] The present application does not limit the structure of the component transfer tool 30. In one embodiment, the component transfer tool 30 is an I-shaped component transfer tool or a U-shaped component transfer tool, and can also be a component transfer tool with other structures.

[0047] Furthermore, in order to further strengthen the management and monitoring of the components 50, in one embodiment, the photovoltaic assembly line that can prevent glass scratches also includes an assembly line guardrail 60 arranged parallel to the transport assembly line 10 and a photoelectric sensing device 61 arranged on the assembly line guardrail 60 facing the transport assembly line 10, and the photoelectric sensing device 61 is used to detect the position information of the component transfer tooling 30.

[0048] By setting up the assembly line guardrail 60, the transport assembly line 10 and the return water are protected to prevent the entry of dust and the like, as well as the intrusion of other components. By detecting the passing components 50 through the photoelectric sensing device 61, it is possible to determine in real time whether the equipment has failed. If the component 50 does not pass within the predetermined time, it means that the component 50 has not been transferred to the tooling 30 or there is a failure in the transportation of the tooling 30, and quick maintenance can be performed in real time.

[0049] This application does not limit the specific location and number of the photoelectric sensing devices 61. Generally, the spacing between adjacent photoelectric sensing devices 61 is equal to the length of the component transfer tooling 30. In this way, each tooling 30 can be accurately positioned, thereby improving management efficiency.

[0050] The present application does not limit the mode of transport of the component transfer tooling 30, which may be free running or track running. However, due to the need for standardized transportation, in one embodiment, a base plate is provided at the bottom of the component transfer tooling 30 for connecting to the guide rail of the transport line 10 or the return line 20.

[0051] By adopting rail transportation, precise transportation can be achieved, and the accurate transmission of component 50 between the front station and the back station can be improved without having a negative impact on subsequent processes.

[0052] In this application, the structure of the component transfer tool 30 is not limited. It can be a simple structure, or it can have a structure such as a cylinder, or other structures. For example, after the complete component 50 is transported at the second station, the top is automatically lowered. That is, during the entire process, the load increases due to the increase in components 50, and the height of the top is raised at this time. After the component 50 is transported and transferred to the return assembly line 20, the load decreases and the height is automatically lowered. The use of a high structure only requires the addition of a pressure sensor and a lifting device. In addition, during the transfer process from the return assembly line 20 to the transport assembly line 10, the tool can be transported or self-propelled. For example, the wheel set can be rotated 90 degrees. That is, during the entire process, the turning is a 90-degree counterclockwise or clockwise rotation. The structure is simple.

[0053] This application does not limit the structure and control method of the controller. In one embodiment, the controller includes a model signal collector, a PLC and a pneumatic control valve. After the model signal collector generates a control scheme based on the current model of the component 50, the PLC is used to implement parameter control of the transport line 10, the return line 20 and the lifting mechanism 40.

[0054] By using a model signal collector to collect signals and then operating according to a predetermined model, the stability and reliability of operation are improved. The use of PLC for control can improve the accuracy of transportation control parameters. The use of pneumatic control valves has a simple and reliable control method.

[0055] The present application includes but is not limited to the above-mentioned controller structure.

[0056] For further management, in one embodiment, the photovoltaic assembly line that can prevent glass scratches also includes a monitor set on the assembly line guardrail 60 for photographing the current working status of the transport assembly line 10 and the return assembly line 20.

[0057] By setting up monitors to monitor the transport assembly line 10 and the return assembly line 20, real-time monitoring and rapid fault location can be achieved, thereby improving management efficiency.

[0058] In this application, there is no limit on the number of transport lines 10 and return lines 20. Since the height of the return line 20 is relatively low, in order to reduce the difficulty of construction, in one implementation, the first transport line 10, the first return line 20, the second return line 20 and the second transport line 10 are arranged in sequence at equal intervals between the adjacent parallel line guardrails 60.

[0059] In this way, the transport assembly line 10 is on the outside, and the return assembly line 20 is on the inside. The two return assembly lines 20 are adjacent to each other. In this way, the low-lying part of the return assembly line 20 can be concentrated to reduce the difficulty of construction. Moreover, in this way, if a component transfer tooling 30 fails, the first return assembly line 20 and the second return assembly line 20 can be linked and the component transfer tooling 30 of the other party can be used. This can reduce the occurrence rate of failures, achieve mutual backup, and improve reliability of use.

[0060] This application does not limit the number and location of the return lines 20 and the transport lines 10 .

[0061] In summary, the photovoltaic assembly line and control method thereof that can prevent glass scratches provided in the embodiment of the present application, after detecting that the first station outputs the component, controls the component transfer tooling to receive the component, then lifts the component and transports the component to the front end of the second station, and sends a component lifting completion signal to the second station. After the second station component receives the lifting completion signal, it takes away the component lifted by the component transfer tooling and outputs a component reception completion signal to the component transfer tooling; after the component transfer tooling receives the component reception completion signal, it returns to the output end of the first station to wait. Since the component is in a lifting state between the first station and the second station and is in a relative stationed state with the component transfer tooling, it will not move relative to other components, reducing the possibility of scratches on the component, solving the problems of coating damage, scratches and marks on double-layer coated glass, improving the product yield, and reducing component costs. The structure is simple. The use of a lifting assembly line reduces the friction generated during the component circulation process, solves the problems of coating damage, scratches and marks on double-layer coated glass, improving the yield, and reducing production costs.

[0062] The above is a detailed introduction to the photovoltaic assembly line and control method for preventing glass scratches provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in several ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
