Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly relates to an automatic welding device for processing photovoltaic modules. Background Art

[0002] As a core component of a solar power generation system, the welding quality of a photovoltaic module directly affects the electrical conductivity, mechanical strength, and service life of the module. Currently, in the welding process of photovoltaic modules, the string welding process (connecting solar cells in series through solder tapes) is a key step, and the mainstream equipment includes fully automatic string welders and semi-automatic welding devices. In the prior art, the following technical bottlenecks generally exist in traditional welding devices: Most devices require manual placement of solar cell tapes or solder tapes batch by batch, and cannot be seamlessly connected to upstream production lines (such as solar cell sorting and layout equipment), resulting in limited welding efficiency (such as frequent downtime waiting for feeding); moreover, when manually placing the tapes, it is easy to cause tape deviation or stacking due to operation errors, affecting subsequent positioning accuracy, and even causing welding misalignment, virtual welding and other defects; in traditional devices, the positioning of solar cells or solder tapes usually relies on manual adjustment of jigs, which is time-consuming and laborious and difficult to ensure consistency; although some devices have mechanical positioning functions, they require manual triggering of the fixing mechanism, and cannot achieve full-process automation of "feeding - positioning - fixing". After welding, the workpiece still needs to be manually released, increasing labor intensity and possibly causing component damage due to uneven disassembly force; The welded components need to be manually transferred to a flipping table or cutting equipment, which is prone to bump damage; the cutting process is often independent of the welding device, resulting in a long logistics path and production capacity waste; welding quality inspection (such as appearance defects, welding strength) mostly relies on manual visual inspection or off-line sampling inspection, and cannot provide real-time feedback data during the welding process, making it difficult to achieve on-line rejection of defective components and affecting yield control.

[0003] In view of the above problems, this invention document proposes an automatic welding device for processing photovoltaic modules. Summary of the Invention

After passing through the inclined surface of the inclined panel, the automatic positioning assemblies automatically rotate and position the photovoltaic modules. A passive feeding assembly is arranged on the upper belt conveyor assembly. The upper belt conveyor assembly conveys the photovoltaic modules, causing the passive feeding assembly to move along, so as to automatically feed the materials. And the welded photovoltaic modules are conveyed to the lower part. If they fall off when in a suspended state, it proves that there is a problem of insecure welding.

[0013] Preferably, a sliding rod is slidably connected in the fixed sleeve. One end of the sliding rod is fixedly connected to the movable cylinder. A return spring is fixedly connected between the inner wall of the movable cylinder and the fixed sleeve. An arc-shaped groove and a straight groove are formed in the fixed sleeve. One end of the straight groove communicates with the arc-shaped groove. A ball rod is fixedly connected to the inner wall of the outer ring structure.

[0014] Preferably, the outer ring structure is rotatably installed on the movable cylinder through a bearing. A positioning pressing plate is fixedly connected to one side of the outer ring structure.

[0015] Compared with the prior art, the present invention provides an automatic welding device for processing photovoltaic modules, which has the following beneficial effects: 1. For the automatic welding device for processing photovoltaic modules, the photovoltaic module can be smoothly conveyed by the upper belt conveying component. The tape of the passive feeding component moves along with it and is pressed against the photovoltaic module by the pressing roller structure, so that the tape can be automatically placed and the precise laying of the tape can be maintained, avoiding the problems of welding misalignment and false soldering, laying a solid foundation for high-quality welding. And the conveying component drives the automatic positioning component to move, so that the automatic positioning component rotates through the inclined panel and automatically positions the photovoltaic module to keep the photovoltaic module stably welded. After welding, the photovoltaic module is conveyed and discharged, and the automatic positioning component automatically releases the fixation, so that the photovoltaic module can be continuously conveyed, and thus continuous welding operations can be carried out. Moreover, the tape is automatically laid on the photovoltaic module to achieve seamless butt joint for welding operations, improving the welding efficiency and providing strong support for the large-scale and high-efficiency production of photovoltaic modules.

[0016] 2. For the automatic welding device for processing photovoltaic modules, the welded photovoltaic module is conveyed by the upper belt conveying component, so that the photovoltaic module can be smoothly placed on the lower belt conveying component. The lower belt conveying structure conveys the photovoltaic module to the roller group conveying structure, and then the photovoltaic module cutting component performs cutting and separating operations on the photovoltaic module. The whole process is closely connected and completed in one go. Each link cooperates efficiently and orderly, greatly shortening the operation time.

[0017] 3. The automatic welding device for processing photovoltaic modules conveys the photovoltaic modules through the upper belt conveying component, enabling the passive feeding component to follow the conveying belt, thus facilitating direct welding by the welding component. After welding, the photovoltaic modules are conveyed downward, causing them to be suspended between the upper belt conveying component and the lower belt conveying component, thereby enabling detection of whether the photovoltaic modules are firmly welded. After detection, the photovoltaic modules are directly discharged onto the lower belt conveying component and then directly cut by the photovoltaic module cutting component, thus enabling rapid processing of photovoltaic modules. This method can, after the welding process is completed, detect the welding quality of photovoltaic modules in real time to ensure that each product meets the standards. Moreover, the detection and cutting links are closely connected and highly coordinated, greatly shortening the processing cycle and enabling the photovoltaic modules to quickly complete the entire process from welding to cutting, providing a strong guarantee for the efficient production of the photovoltaic industry.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Embodiment 1: Refer to Figures 1 - 4 and Figures 6 - 10 , an automatic welding device for processing photovoltaic modules, including a post-welding processing mechanism 100, and a photovoltaic module welding mechanism 200 is arranged above the post-welding processing mechanism 100; The post-welding processing mechanism 100 includes a processing base 101, a lower belt conveyor assembly 102 is arranged on the processing base 101, and photovoltaic module cutting assemblies 103 are arranged on both the upper and lower sides of the lower belt conveyor assembly 102; The photovoltaic module welding mechanism 200 includes an upper belt conveyor assembly 201. The upper belt conveyor assembly 201 includes two upper mounting brackets 2011. An upper belt conveyor structure 2012 is arranged between the two upper mounting brackets 2011. The upper belt conveyor structure 2012 can be fixed by the upper mounting brackets 2011 to ensure the stability of the upper belt conveyor structure 2012. And the upper belt conveyor structure 2012 can convey and feed the photovoltaic modules, thus facilitating the welding operation of the photovoltaic modules. Above the upper belt conveyor assembly 201, there is a welding assembly 202. The welding assembly 202 includes two side mounting brackets 2021. The two side mounting brackets 2021 are respectively fixedly connected to the two upper mounting brackets 2011. Above the two side mounting brackets 2021, there is a device support base 2022. The welding device 2023 can be installed and fixed by the side mounting brackets 2021 and the device support base 2022 to ensure the stability of the welding device 2023. The welding device 2023 is fixedly installed on the device support base 2022. The two side mounting brackets 2021 are respectively fixedly connected to the two inclined panels 204. Due to the end face of the inclined panel 204 being designed as an inclined surface, the rolling ball structure 2065 can generate a squeezing movement when passing through the inclined surface of the inclined panel 204, thereby controlling the movement of the movable cylinder 2062, enabling the outer ring structure 2063 to drive the ball screw 2069 to slide in the arc groove 20610. The cooperation between the ball screw 2069 and the arc groove 206|0 can drive the positioning pressure plate 2064 to rotate, making the positioning pressure plate 2064 correspond to the photovoltaic module. At this time, continue to press down the positioning pressure plate 2064, so that the positioning pressure plate 2064 can position the photovoltaic module and keep the photovoltaic module stable. And this operation can be automatically positioned, making the operation more convenient and fast. Between the two inclined panels 204, there is a pressure roller structure 203. The pressure roller structure 203 can press the passing strip 2055 onto the photovoltaic module, so that the strip 2055 is kept in contact with the photovoltaic module, thus facilitating the subsequent welding processing of the photovoltaic module. The welding assembly 202 is connected to two inclined panels 204. On the upper belt conveyor assembly 201, there are multiple automatic positioning components 206. The automatic positioning component 206 includes a mounting base 2061 and an outer ring structure 2063. The mounting base 2061 is fixedly installed on the upper belt conveyor structure 2012. A fixed sleeve 2068 is fixedly connected to the mounting base 2061. A movable cylinder 2062 is sleeved outside the fixed sleeve 2068. The movable cylinder 2062 can be guided by the fixed sleeve 2068 to slide smoothly up and down. One end of the movable cylinder 2062 is rotatably connected to a rolling ball structure 2065. Due to the rolling property of the rolling ball structure 2065, the frictional resistance with the inclined panel 204 can be reduced, so that the rolling ball structure 2065 can move smoothly and maintain the smoothness of the operation. A slide rod 2067 is slidably connected in the fixed sleeve 2068. The shape of the slide rod 2067 is a polygonal structure, and the inner shape of the fixed sleeve 2068 is adapted to the shape of the slide rod 2067.The sliding rod 2067 can slide smoothly in the fixed sleeve 2068. One end of the sliding rod 2067 is fixedly connected to the movable cylinder 2062. A return spring 2066 is fixedly connected between the inner wall of the movable cylinder 2062 and the fixed sleeve 2068. The return spring 2066 drives the movable cylinder 2062 to reset upward, causing the movable cylinder 2062 to drive the outer ring structure 2063 to move. After the ball screw 2069 enters the arc-shaped groove 20610, it can drive the positioning pressure plate 2064 to rotate, thereby automatically removing the positioning of the photovoltaic module, facilitating actual operation and saving time. The fixed sleeve 2068 is provided with an arc-shaped groove 20610 and a linear groove 20611. Through the communication between the linear groove 20611 and the arc-shaped groove 20610, the ball screw 2069 can smoothly enter the linear groove 20611 through the arc-shaped groove 20610, keeping the ball screw 2069 sliding and preventing the outer ring structure 2063 and the positioning pressure plate 2064 from rotating again and affecting the positioning of the photovoltaic module. One end of the linear groove 20611 is communicated with the arc-shaped groove 20610. The inner wall of the outer ring structure 2063 is fixedly connected with a ball screw 2069. The ball screw 2069 switches between sliding in the linear groove 20611 and the arc-shaped groove 20610. The outer ring structure 2063 is rotatably installed on the movable cylinder 2062 through a bearing. The outer ring structure 2063 can maintain stable rotation through the bearing, enabling the positioning pressure plate 2064 to rotate smoothly. A rubber layer is added to one side of the positioning pressure plate 2064, which can protect the photovoltaic module and increase firmness. A positioning pressure plate 2064 is fixedly connected to one side of the outer ring structure 2063; After the automatic positioning component 206 passes through the inclined surface of the inclined panel 204, it automatically rotates and positions the photovoltaic module. A passive feeding component 205 is arranged on the upper belt conveying component 201. The passive feeding component 205 includes two limiting cylinders 2051. Both of the two limiting cylinders 2051 are rotatably installed on two upper mounting brackets 2011 through bearings respectively. The limiting cylinder 2051 can rotate smoothly through the bearing, so that the material-releasing disc 2053 can rotate to release the material belt 2055, thereby meeting the automatic conveying operation of the material belt 2055. A same connecting shaft 2052 is arranged in the two limiting cylinders 2051. The connecting shaft 2052 is inserted into the limiting cylinder 2051, and the position of the connecting shaft 2052 can be fixedly connected by bolts, so that the connecting shaft 2052 is stably connected with the limiting cylinder 2051, maintaining the stability of the material-releasing disc 2053. And the connecting shaft 2052 can be removed from the limiting cylinder 2051, thus facilitating the replacement of the material belt 2055. A material-releasing disc 2053 is fixedly connected to the connecting shaft 2052, and a material belt 2055 is wound around the material-releasing disc 2053. The material belt 2055 bypasses the guide wheel 2054. The guide wheel 2054 can guide the material belt 2055, and the rolling of the guide wheel 2054 can reduce the frictional resistance to the material belt 2055, maintaining the smooth conveying of the material belt 2055 and reducing the wear of the material belt 2055, ensuring the quality of the material belt 2055, and thus ensuring the welding quality of the photovoltaic module. The photovoltaic module is pressed by the pressing roller structure 203. The guide wheel 2054 is fixedly connected to one side of the two upper mounting brackets 2011. The photovoltaic module is conveyed by the upper belt conveying component 201, so that the passive feeding component 205 moves along with it, thereby automatically discharging the material. And the welded photovoltaic module is conveyed to the lower part. If it falls off when in a suspended state, it proves that there is a problem of insecure welding.

[0023] In this embodiment: The photovoltaic module can be smoothly conveyed by the upper belt conveying structure 2012, and the tape 2055 of the passive feeding component 205 moves along with it and is pressed against the photovoltaic module by the pressing roller structure 203, so that the tape 2055 can be automatically placed and the precise laying of the tape 2055 can be maintained, avoiding the problems of welding misalignment and false soldering, laying a solid foundation for high-quality welding. Moreover, the conveying component drives the automatic positioning component 206 to move, so that the ball structure 2065 is extruded by the inclined plane of the inclined panel 204, causing the ball structure 2065 to press down the movable cylinder 2062. The movable cylinder 2062 drives the ball screw 2069 to move through the outer ring structure 2063. The cooperation between the ball screw 2069 and the arc groove 20610 can drive the outer ring structure 2063 and the positioning pressing plate 2064 to rotate. After the positioning pressing plate 2064 rotates, it corresponds to the photovoltaic module. At this time, by continuing to press down, the positioning pressing plate 2064 automatically positions the photovoltaic module to keep the photovoltaic module stably welded. After welding, the photovoltaic module is conveyed and discharged. When the ball structure 2065 disengages from the inclined panel 204, the return spring 2066 drives the movable cylinder 2062 to reset upward, causing the positioning pressing plate 2064 to rotate and release the fixation, enabling the continuous conveyance of the photovoltaic module, so as to carry out continuous welding operations. Moreover, the tape 2055 is automatically laid on the photovoltaic module to achieve seamless butt joint for welding operations, improving the welding efficiency and providing strong support for the large-scale and high-efficiency production of photovoltaic modules.

[0024] Embodiment 2: Refer to Figures 4 - 6 , an automatic welding device for processing photovoltaic modules, including a lower belt conveying component 102. The lower belt conveying component 102 includes two lower fixing frames 1021. The lower belt conveying structure 1022 and the roller group conveying structure 1023 can be fixed through the lower fixing frames 1021 to ensure the stability of the lower belt conveying structure 1022 and the roller group conveying structure 1023. The two lower fixing frames 1021 are respectively fixedly connected below the upper mounting bracket 2011. A lower belt conveying structure 1022 and a roller group conveying structure 1023 are arranged between the two lower fixing frames 1021. The photovoltaic module to be welded can be smoothly conveyed to the roller group conveying structure 1023 by the lower belt conveying structure 1022, and the roller group conveying structure 1023 can continue to convey the photovoltaic module to the cutting area. There is a gap between the roller group conveying structures 1023, so that the two cutting knives 1031 can move relative to each other smoothly to complete the cutting and separation of the photovoltaic module. The upper belt conveying component 201 includes two upper mounting brackets 2011, and an upper belt conveying structure 2012 is arranged between the two upper mounting brackets 2011; The photovoltaic module cutting assembly 103 includes a fixed plate 1032, which is fixedly connected between two lower fixing frames 1021. An electric push rod 1033 is fixedly installed on the fixed plate 1032. The position of the electric push rod 1033 can be fixed through the fixed plate 1032 to ensure the stability of the electric push rod 1033. The electric push rod 1033 controls the movement of the cutting knife 1031, enabling the cutting knife 1031 to complete the cutting and separation of the photovoltaic module. One end of the electric push rod 1033 is fixedly installed with the cutting knife 1031.

[0025] In this embodiment: The welded photovoltaic module is conveyed by the upper belt conveying structure 2012, so that the photovoltaic module is smoothly placed on the lower belt conveying structure 1022, and the lower belt conveying structure 1022 conveys the photovoltaic module to the roller group conveying structure 1023. The roller group conveying structure 1023 continues to convey the photovoltaic module. When the photovoltaic module reaches the cutting area, the cutting knife 1031 is controlled by the electric push rod 1033 to perform the cutting and separation operation on the photovoltaic module. The whole process is closely connected and completed in one go. Each link cooperates efficiently and orderly, greatly shortening the operation time.

[0026] Example 3: Refer to Figures 1 - 2 and Figure 4 A kind of automatic welding device for photovoltaic module processing, which includes a post-welding treatment mechanism 100. The post-welding treatment mechanism 100 includes a processing base 101. A lower belt conveying assembly 102 is arranged on the processing base 101. Photovoltaic module cutting assemblies 103 are arranged on both the upper and lower sides of the lower belt conveying assembly 102; The photovoltaic module welding mechanism 200 includes an upper belt conveying assembly 201. A welding assembly 202 is arranged above the upper belt conveying assembly 201. Two inclined panels 204 are connected to the welding assembly 202. A plurality of automatic positioning assemblies 206 are arranged on the upper belt conveying assembly 201. After passing through the inclined surface of the inclined panel 204, the automatic positioning assemblies 206 automatically rotate and position the photovoltaic module. A passive feeding assembly 205 is arranged on the upper belt conveying assembly 201. The photovoltaic module is conveyed by the upper belt conveying assembly 201, so that the passive feeding assembly 205 follows the movement to automatically feed the material. And when the welded photovoltaic module is conveyed to the lower part and falls off in a suspended state, it proves that there is a problem of insecure welding.

[0027] In this embodiment: The photovoltaic module is conveyed by the upper belt conveying assembly 201, so that the passive feeding assembly 205 follows the conveying belt 2055, which facilitates the direct welding process by the welding assembly 202. After welding, the photovoltaic module is conveyed downward, and the photovoltaic module falls and is suspended between the upper belt conveying assembly 201 and the lower belt conveying assembly 102, so that it can be detected whether the photovoltaic module is welded firmly. After detection, the photovoltaic module is directly discharged onto the lower belt conveying assembly 102 and then directly cut by the photovoltaic module cutting assembly 103, thereby quickly processing the photovoltaic module. This method can detect the welding quality of the photovoltaic module in real time after the welding process is completed, ensuring that each product meets the standards. Moreover, the detection and cutting links are closely connected and highly coordinated, greatly shortening the processing cycle, enabling the photovoltaic module to quickly complete the full-process processing from welding to cutting, providing a strong guarantee for the efficient production of the photovoltaic industry.

[0028] Working principle: When performing the welding operation of the photovoltaic module, the photovoltaic module is placed on the upper belt conveying structure 2012, and the upper belt conveying structure 2012 conveys the photovoltaic module. When the ball structure 2065 passes through the inclined surface of the inclined panel 204, the ball structure 2065 presses down the movable cylinder 2062, and the movable cylinder 2062 drives the deformation of the return spring 2066. Moreover, the movable cylinder 2062 drives the ball screw 2069 to move through the outer ring structure 2063. The ball screw 2069 slides in the arc-shaped groove 20610 and rotates by itself through the arc surface of the arc-shaped groove 20610, so that the outer ring structure 2063 drives the positioning pressing plate 2064 to rotate. The positioning pressing plate 2064 is located above the photovoltaic module. At this time, continue to press down, so that the positioning pressing plate 2064 positions the photovoltaic module. When the photovoltaic module is conveyed to the welding area, at this time, the welding device 2023 moves downward and performs the welding operation of the photovoltaic module through the belt 2055; After welding, the upper belt conveying structure 2012 continues to convey the photovoltaic module out of the welding area. At the same time, the photovoltaic module to be welded reaches the welding area again. During the conveying process, the feeding tray 2053 releases the belt 2055, and the belt 2055 stretches along with the photovoltaic module. Moreover, the belt 2055 continues to be accurately pressed on the photovoltaic module through the pressing roller structure 203 for further welding operation; After the welded photovoltaic module is separated from the upper belt conveying structure 2012, since the belt 2055 connects each photovoltaic module, the photovoltaic module is smoothly conveyed downward. When the photovoltaic module is in a suspended state, its welding firmness can be detected. The adhered photovoltaic module is smoothly placed on the lower belt conveying structure 1022, and the lower belt conveying structure 1022 conveys the photovoltaic module and transfers it to the roller group conveying structure 1023. When the photovoltaic module is in the cutting area, at this time, the electric push rod 1033 controls the movement of the cutting knife 1031, so that the cutting knife 1031 can cut off the belt 2055, and the photovoltaic module is smoothly output to complete the cutting process.
