Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter assembly and production, and in particular to an aging test device for wall-mounted products. Background Technology

[0002] A photovoltaic (PV) inverter is an inverter that converts the variable DC voltage generated by photovoltaic solar panels into AC power at the grid frequency. This AC power can be fed back into commercial power transmission systems or supplied to off-grid systems. PV inverters are essential components of PV array systems and can be used in conjunction with general AC-powered equipment.

[0003] Due to their weight and size, large photovoltaic (PV) inverters are typically assembled flat on tables or conveyor lines, limiting their flexibility in repositioning. Personnel assembling the internal circuit boards must bend over to align screws with mounting holes. After assembly, aging tests are conducted in an aging chamber to effectively filter out substandard inverters. This requires moving the large PV inverters from the assembly conveyor line to a transport vehicle, which then transfers them to the aging chamber for testing. The increased weight and size of the assembled inverters make them difficult to move. Therefore, assembling and aging-testing large PV inverters is quite inconvenient.

[0004] Therefore, this utility model provides an aging test device for wall-mounted products, solving the problem of inconvenience in assembling and aging tests of large photovoltaic inverters. Utility Model Content

The track is laid between the assembly station and the aging station. There are two bottom crossbeams, symmetrically and detachably mounted on the bottom surface of the frame. Roller sets are provided on the surfaces of the two bottom crossbeams close to each other. The track is sandwiched between the two roller sets. Each roller set includes several rollers. The centerline of the roller is set vertically; the lower end of the support frame is set on the vehicle frame, and the sleeve, upper bracket and lower bracket are set sequentially from top to bottom.

The middle parts of the first column, the longitudinal beam, and the second column are connected sequentially through the central crossbeam. The center lines of the first column, the longitudinal beam, and the second column are coplanar. The two ends of the upper bracket are slidably mounted on the first column and the second column, respectively. The two ends of the lower bracket are detachably mounted on the first column and the second column, respectively, by fasteners. The center positions of the upper bracket and the lower bracket are detachably mounted on the longitudinal beam by fasteners.

This avoids the instability caused by the wall-mounted structure on the back of the product casing, which would otherwise affect the assembly and processing.

[0016] After assembly and processing, one end of the adapter component remains connected to the interface on the product, allowing the entire photovoltaic inverter product, including the chassis, to be smoothly transferred along the track to the aging station, eliminating the need for manual handling of the photovoltaic inverter. The other end of the adapter component is then connected to the wiring of the testing equipment for aging testing. This facilitates the assembly and aging testing of large photovoltaic inverter products. Attached Figure Description

[0024] The adapter includes a cable, a male plug, and a female plug. The male plug and female plug are respectively connected to both ends of the cable. The male plug is used to connect to test equipment, and the female plug is used to connect to a photovoltaic inverter product.

[0025] The frame 1 includes a main frame and casters. The casters are located at the edge of the bottom surface of the main frame, and the lower end of the casters is located below the roller assembly.

[0026] The upper support 6 includes an upper rectangular plate and an upper fixed frame.

The lower support 7 includes a lower rectangular plate and a lower fixed frame.

[0027] The support frame 2 includes a first column, a second column, a central crossbeam, and a longitudinal beam. The first column, the longitudinal beam, and the second column are vertically arranged on the upper surface of the frame 1. The middle parts of the first column, the longitudinal beam, and the second column are connected in sequence through the central crossbeam. The center lines of the first column, the longitudinal beam, and the second column are coplanar. The two ends of the upper bracket are slidably mounted on the first column and the second column, respectively. The two ends of the lower bracket are detachably mounted on the first column and the second column, respectively, through fasteners.

When the vehicle frame moves, two sets of rollers at the bottom of the frame move along the track, and the frame and support frame remain stable throughout the movement. The photovoltaic inverter's casing is relatively lightweight before assembly, making it easy for personnel to handle. The photovoltaic inverter is hung on the product rack of the upper support. Since the total weight of the photovoltaic inverter and the upper support is greater than that of the lower support, the upper support descends. Because the two ends of the traction rope are tied to the upper and lower supports, and the middle of the traction rope is located at the upper end of the frame, the lower support at the other end of the traction rope will rise when the upper support descends. Simply fix the lower support to the support frame before assembly and adjust its installation position according to the size of the photovoltaic inverter. This allows the upper support and the photovoltaic inverter on it to be adjusted to different heights during assembly, accommodating various sizes and specifications of photovoltaic inverters, and also accommodating the height of assembly personnel. After assembly, the entire vehicle frame and the photovoltaic inverter on it are transferred to the aging station for aging testing.

[0033] In one embodiment, both the upper and lower sliding members are guide sleeves, and both the first and second columns are smooth cylinders. The upper sliding member is detachably connected to the upper bracket 6 by screws, and the lower sliding member is detachably connected to the lower bracket 7 by screws. The upper and lower sliding members are provided with threaded holes that match the screw threads.

[0034] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
