Description

Technical Field

[0001] This utility model relates to the field of weighing equipment, and in particular to a novel automatic weighing device for welding strips inside a photovoltaic string welding machine. Background Technology

[0002] In the production of photovoltaic string welding machines, the welding strip is a key connecting component, and its weight accuracy directly affects the welding quality and power generation efficiency of photovoltaic modules. Therefore, accurate weighing of the welding strip is an important step in the production process of photovoltaic string welding machines. However, existing welding strip weighing equipment in photovoltaic string welding machines has many shortcomings in practical applications: On the one hand, traditional weighing equipment mostly adopts single-point weighing or single-sensor weighing methods, making it difficult to simultaneously detect the weight of the welding strip at multiple points. At the same time, most equipment can only weigh a single group of welding strips, failing to meet the need for simultaneous weighing of multiple groups of welding strips. Uneven force can easily lead to poor accuracy and stability of weighing data, and some equipment lacks effective limiting structures, making it easy for the load-bearing components to undergo lateral displacement during the weighing process, further affecting the weighing accuracy. On the other hand, the installation position of the welding strip fixing structure in existing equipment is relatively fixed, lacking flexible adjustment space, making it difficult to adapt to diverse welding strip weighing operations. The overall versatility of the equipment is low. In addition, the adjustment function of traditional welding strip fixing structures is limited, making it difficult to simultaneously adapt to welding strips of different specifications. This results in poor adhesion between some fixing structures and the outer surface of the welding strip, affecting the quality and stability of subsequent welding operations.

[0003] This invention proposes a novel automatic weighing device for welding strips inside a photovoltaic string welding machine, which can improve weighing accuracy and stability, enhance equipment adaptability and versatility, and ensure the stability of welding strip fixation. Utility Model Content

[0004] The main purpose of this utility model is to propose a new type of automatic weighing device for welding strips inside a photovoltaic string welding machine, which aims to solve the problems of poor accuracy and stability of weighing welding strips inside the photovoltaic string welding machine and poor equipment adaptability and versatility.

[0005] To address the aforementioned problems, this utility model proposes a novel automatic weighing device for welding strips inside a photovoltaic string welding machine, comprising: a base, with a ramp at the right end of each base; foot pads fixedly connected to both the front and rear ends of the base; weighing plates on both the front and rear sides of the upper end of the base; weighing sensors at the four corners of the lower end of each weighing plate; the weighing sensors being electrically connected to a power source via power lines; a vertical limiting platform at the middle of the lower end of each weighing plate; a connecting plate fixedly connected to the upper end of each weighing plate; a welding strip fixing frame fixedly connected to the upper end of each connecting plate; multiple mounting holes penetrating the interior of each welding strip fixing frame at its far end; welding strip fixing devices rotatably connected inside each of the multiple mounting holes; and welding strips fitted onto the exterior of each of the multiple welding strip fixing devices.

[0006] In one embodiment, the welding strip fixing device includes threaded fixing rods, with threaded fixing rods rotatably connected to the interior of multiple mounting holes, and one end of each threaded rod being threaded.

[0007] In one embodiment, each of the multiple threaded fixing rods has a threaded sleeve threaded onto one end of its threaded end, and each of the multiple threaded sleeves has a hexagonal head for turning at the end furthest from the welding strip fixing frame.

[0008] In one embodiment, a connecting block is fitted onto the outside of a plurality of threaded sleeves, and the upper and lower sides of the plurality of connecting blocks near the end of the welding strip fixing frame are provided with sliding grooves.

[0009] In one embodiment, a rotating screw is rotatably connected inside each of the two grooves, and the ends of the two rotating screws pass through the upper and lower ends of the connecting block, respectively.

[0010] In one embodiment, two rotating lead screws are fixedly connected to hexagonal flat heads at their far ends, and threaded lifting blocks are threadedly sleeved on the outside of both rotating lead screws, with the two threaded lifting blocks slidably connected inside the two slide grooves respectively.

[0011] In one embodiment, the two threaded lifting blocks are fixedly connected to the support plates at the ends of the two support plates that are close to each other, and the ends of the two support plates that are far from each other are provided with a certain curvature. The two support plates are fitted with welding strips.

[0012] Beneficial effects:

[0013] 1. Multiple sets of weighing sensors perform multi-point synchronous detection of the welding strip weight. At the same time, the two weighing plates can weigh the welding strips on the two welding strip fixing frames respectively, which effectively improves the accuracy and stability of the weighing data. The vertical limit platform can limit the weighing plate in the vertical direction during the load-bearing process, preventing it from lateral displacement due to uneven force or welding strip placement deviation, thus ensuring the accuracy of the weighing operation and the stability of the equipment structure.

[0014] 2. The multiple mounting holes provide multiple installation options for the welding strip fixing structure, which can be flexibly adjusted according to the requirements of different specifications and quantities of welding strips. This enhances the equipment's adaptability to diverse welding strip weighing operations, meets the usage requirements of different welding strip processing scenarios in photovoltaic string welding machine production, and improves the overall versatility of the equipment.

[0015] 3. By adjusting the length of the threaded sleeve extending from the welding strip fixing bracket by turning the hexagonal head, the overall extension size of the welding strip fixing structure can be adjusted to meet the fixing requirements of welding strips of different lengths. By rotating the hexagonal flat head, the rotating screw is driven to rotate, causing the threaded lifting block to move up and down along the slide groove, which in turn drives the support plate to adjust up and down. The arc design of the far end of the two support plates can better fit the outer surface of the welding strip, which can achieve stable clamping of welding strips of different diameters, adapt to the fixing of various specifications of welding strips, ensure the stability of the welding strip position during the weighing process, and avoid weighing errors caused by improper fixing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides a novel automatic weighing device for welding strips inside a photovoltaic string welding machine, comprising: a base 1, a ramp 2 on the right end of the base 1, a foot pad 3 fixedly connected to both the front and rear ends of the base 1, a weighing plate 4 on both the front and rear sides of the upper end of the base 1, a weighing sensor 5 at the four corners of the lower end of the two weighing plates 4, the weighing sensor 5 being electrically connected to a power source via a power cord, a vertical limiting platform 6 at the middle of the lower end of the two weighing plates 4, a connecting plate 7 fixedly connected to the upper end of the two connecting plates 4, a welding strip fixing frame 8 fixedly connected to the upper end of the two connecting plates 7, multiple mounting holes 9 penetrating through the interior of the two welding strip fixing frames 8 at their far ends, welding strip fixing devices rotatably connected inside the multiple mounting holes 9, and welding strips fitted onto the exterior of the multiple welding strip fixing devices.

[0026] Preferably, the welding strip fixing device includes a threaded fixing rod 10, and the interior of a plurality of mounting holes 9 is rotatably connected to a threaded fixing rod 10. One end of the plurality of threaded rods is provided with threads, and the threaded end of the plurality of threaded fixing rods 10 is threadedly sleeved with a threaded sleeve 11. The end of the plurality of threaded sleeves 11 that is far from the welding strip fixing frame 8 is provided with a screw-on hexagonal head 12.

[0027] Preferably, a connecting block 13 is sleeved on the outside of a plurality of threaded sleeves 11. The upper and lower sides of the plurality of connecting blocks 13 near the welding strip fixing frame 8 are provided with sliding grooves 14. Rotating screws 15 are rotatably connected inside the two sliding grooves 14, and the two rotating screws 15 at opposite ends pass through the upper and lower ends of the connecting block 13 respectively.

[0028] Preferably, each of the two rotating lead screws 15 has a hexagonal flat head 16 fixedly connected to its far end. Each of the two rotating lead screws 15 has a threaded lifting block 17 threadedly sleeved on its exterior. The two threaded lifting blocks 17 are slidably connected inside the two sliding grooves 14. Each of the two threaded lifting blocks 17 has a support plate 18 fixedly connected to its near end with the welding strip fixing frame 8. Each of the two support plates 18 has a certain curvature at its far end. The welding strip is sleeved on the exterior of the two support plates 18.

[0029] In use, first, according to the specifications and quantity of the welding strip, select a suitable position among the multiple mounting holes 9 that run through the front and rear of the two welding strip fixing frames 8, and install the threaded fixing rod 10 of the welding strip fixing device into the selected mounting hole 9 (each welding strip fixing frame 8 has a maximum of 24 mounting holes 9). Then, put the welding strip on the outside of the two support plates 18. According to the diameter specifications of the welding strip, rotate the hexagonal flat head 16 at the far end of the two rotating screws 15 on the connecting block 13, causing the rotating screws 15 to rotate inside the slide groove 14. Due to the thread lifting and lowering... Block 17 is threadedly connected to the rotating screw 15 and slidably connected within the groove 14. When the rotating screw 15 rotates, it drives the threaded lifting block 17 to move up and down along the groove 14, thereby driving the support plate 18, which is fixedly connected to the threaded lifting block 17, to adjust up and down until the curved surface of the two support plates 18 at their far ends is tightly fitted with the outer surface of the welding strip, thus achieving a stable clamping of the welding strip. Then, after clamping the welding strip, the threaded sleeve 11 is aligned with the corresponding threaded fixing rod 10 and rotated. According to the width requirement of the welding strip, the threaded sleeve 11 is adjusted by screwing one end of the threaded sleeve 11. Tighten the hexagonal head 12 to move the threaded sleeve 11 along the thread direction of the threaded fixing rod 10, adjust the length of the threaded sleeve 11 extending out of the welding strip fixing frame 8, and thus determine the overall extension dimension of the welding strip fixing structure to fit the width of the welding strip to be weighed. After the welding strip is fixed, start the weighing sensor 5. The two weighing plates 4 weigh the welding strip on their respective welding strip fixing frames 8. The weighing sensors 5 at the four corners of the lower end of the two weighing plates 4 simultaneously perform multi-point detection of the weight of the welding strip on the welding strip fixing frame 8 and transmit the detection data to the respective weighing sensor 5. The display panel enables precise measurement of the weight of the welding strips on the two welding strip holders 8. During this process, the vertical limiting platform 6 continuously limits the vertical position of the load-bearing weighing plate 4, preventing lateral displacement due to uneven force or slight welding strip offset, thus ensuring the accuracy and stability of the weighing data. When it is necessary to weigh welding strips of different specifications or quantities, the installation position of the welding strip fixing structure in the mounting hole 9 can be changed, or the extension length of the threaded sleeve 11 and the height of the support plate 18 can be readjusted to allow the equipment to quickly adapt to new welding strip weighing requirements. The above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the utility model concept and using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
