Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic inverter transportation, and in particular to photovoltaic inverter aerial transportation equipment. Background Art

[0002] Photovoltaic inverter (PV inverter or solar inverter) can convert the variable DC voltage generated by photovoltaic (PV) solar panels into AC power at mains frequency, which can be fed back to the commercial power transmission system or used in off-grid power grids. Photovoltaic inverter is one of the important system balance (BOS) in photovoltaic array system and can be used with general AC-powered equipment. Solar cell modules (also called photovoltaic inverters) are the core part of solar power generation system and the most important part of solar power generation system. Moreover, single solar cells cannot be used directly as power source. As a power source, several single cells must be connected in series or parallel and tightly sealed into components; the function of the solar panel is to convert solar energy into electrical energy, or send it to the battery for storage, or drive the load to work; due to the positive and negative charges of the solar panel, the positive and negative charges in the PN junction area are separated, thus generating an external current field, and the current flows from the bottom of the crystalline silicon wafer battery through the load to the top of the battery, causing a "photovoltaic effect". When a load is connected between the upper and lower surfaces of the solar cell, current will flow through the load, so the solar cell generates current; the more photons the solar cell absorbs, the greater the current generated; solar panels are generally used in conjunction with photovoltaic inverters, which can convert the variable DC voltage generated by photovoltaic solar panels into an inverter with AC frequency of mains power, which can be fed back to the commercial transmission system or used for off-grid power grids, and can then be used with general AC-powered equipment.

[0003] At present, in the production process of solar panels, the main production processes include battery testing, front welding, back connection, lamination laying, component lamination, trimming, framing, welding junction box, high voltage testing and component testing. The purpose of battery testing is to calibrate the output power of the battery, test its output characteristics, determine the quality level of the component, so as to improve the utilization rate of the battery and make qualified battery components. Among them, front welding is to weld the busbar to the main grid line of the front (negative) of the battery. The busbar is a tin-plated copper strip, and the welding strip is spot welded on the main grid line in the form of multiple points. Back welding is to connect the batteries together to form a component string, and position the batteries through a film plate, weld the front electrode (negative electrode) of the "front battery" to the back electrode (positive electrode) of the "back battery", connect them together in sequence and weld leads at the positive and negative electrodes of the component string. After the back connection is completed and passed the inspection, The component strings, glass and cut EVA, glass fiber, and backplane are laid out in a certain layer in preparation for lamination, and the laid batteries are placed in a laminator. The air in the component is extracted by vacuuming, and then the EVA is melted by heating to bond the battery, glass, and backplane together; finally, the component is cooled and taken out; the lamination process is a key step in component production. The lamination temperature and lamination time are determined by the properties of EVA. During lamination, the EVA melts and extends outward due to pressure to solidify to form burrs, so it should be cut off after lamination; and an aluminum frame is installed for the glass component to increase the strength of the component, further seal the battery component, and extend the service life of the battery. The gap between the frame and the glass component is filled with silicone resin; the frames are connected by angle keys, and the high voltage test refers to applying a certain voltage between the component frame and the electrode lead to test the pressure resistance and insulation strength of the component to ensure that the component is not damaged under harsh natural conditions (lightning strikes, etc.).

[0004] Therefore, in the process of processing, transporting and producing the above-mentioned photovoltaic inverters and solar panels, each process is processed separately. In order to realize automated processing of photovoltaic inverters, they are generally transferred or transited through transportation lines. In the existing automated handling or transportation of photovoltaic inverters, the floor area of ​​the workshop is often simply used for automated integrated transportation of photovoltaic inverters, which occupies too much area and wastes space extremely, which makes the connection relationship between the various processes of processing photovoltaic inverters intertwined, which is easy to cause confusion.

[0005] In order to ensure the service life and product qualification rate of photovoltaic inverters, aging tests are required before finished products are shipped out of the warehouse in order to screen out defective or failed components. The aging test first places the photovoltaic inverter on the support tooling bottom plate, and transports the busbar to the test station for aging test by means of carrying tooling transportation. The existing photovoltaic inverters need to be tested on an aging test production line for batch testing during the aging test. The existing aging test production line occupies a large area, resulting in a small available floor space in the workshop.

[0006] For example, the reference publication number is "CN114803057A" and the patent name is "A transport jig and a solar cell production and conveying device", a Chinese invention patent. The transport jig and the solar cell production and conveying device include: a transport jig, the upper surface of which is provided with a first protective plate; a connecting plate, one side wall of which is fixedly connected to a slider, and the slider is provided with two groups; a second protective plate, the cross section of which is a "concave"-shaped structure, and the second protective plate is plugged into the inside of the storage groove; the beneficial effect is: the solar cells are stacked on the transport jig, and during the stacking process, the elastically sliding connecting plate will always hold one side of the solar cell, and the stacking is completed. After completion, pull out the second protective plate, the hinged plate will slide outward along the groove, and when it is pulled to the end, rotate the second protective plate upward with the support rod as the center, and after rotating 90°, the inner wall of the second protective plate and the side wall of the first protective plate fit together, slide the connecting block so that the connecting block is located on one side of the connecting plate, tighten the fixing bolts, and then fix the second protective plate with the fixing column. This structure uses two protective plates to limit the solar cell assembly to prevent the solar cell assembly from falling off during the stacking process. However, this structure cannot actually solve the problem of how to automatically transport the photovoltaic inverter of the solar cell assembly, nor can it reduce the floor space occupied by the production conveyor line.

[0062] The driving motor 41 is connected to the lifting gear 453 of one of the first synchronous shafts 451 through a transmission chain, and the lifting gear 453 of the other first synchronous shaft 451 is connected to the lifting transmission belt 43. The synchronous transmission belt 44 is connected to the transmission gear 454 and the follower gear 455 respectively. The starting end of the synchronous transmission belt 44 is connected to the end of the synchronous transmission belt 44. When the power output end of the driving motor 41 rotates, the transmission chain is driven, thereby driving the lifting gear 453 of one of the first synchronous shafts 451 through the transmission chain, so that one of the first synchronous shafts 451 rotates. Since two transmission gears 454 and a lifting gear 453 are provided on the first synchronous shaft 451, two follower gears 455 are provided on the second synchronous shaft 452, and the synchronous transmission belt 44 is respectively connected to the transmission gear and the follower gear 455, and the two ends of the synchronous transmission belt 44 are butted, so that when the first synchronous shaft 451 rotates, the synchronous transmission belt 44 is driven to rotate by the transmission gear 454, and the synchronous transmission belt 44 drives the follower gear 455 of the second synchronous shaft 452 to realize the dual-axis synchronous rotation, and the synchronous transmission belt 44 moves along the transmission gear 454 and the follower gear 455 of the synchronous dual-axis assembly 45;
