Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery transportation technology, and in particular to a long-distance truck transportation device for small coiled electrode sheets. Background Technology
[0002] Lithium-ion batteries are widely used in power, energy storage, and 3C digital products due to their high operating voltage, high specific energy, long cycle life, and low self-discharge.
[0003] In current production, positive and negative electrode rolls are intermediate products in the lithium-ion battery production process. They are an important and necessary component of lithium-ion batteries. Typically, electrode rolls are quickly transferred within a single workshop for further processing in subsequent stages. They are also transferred between factories and over long distances by truck across regions. Currently, long-distance truck transfers across regions generally use all-metal sealed boxes, which are very expensive, have low utilization rates per unit space, and are extremely heavy and cumbersome.
[0004] To address this problem, we propose a long-distance truck transport device for small-rolled electrode sheets. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a long-distance truck transportation device for small-rolled electrode sheets, which aims to realize long-distance transfer of electrode sheets with low cost and high space utilization.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a long-distance truck transportation device for small-rolled electrode sheets, comprising: a welding bracket, at least two support plates vertically fixed on the top of the welding bracket, a cantilever shaft horizontally fixed on the top of each support plate, the end of the cantilever shaft away from the support plate being fixedly connected to the welding bracket, a limit baffle being coaxially fixed at the end of each cantilever shaft away from the support plate, and a tightening pressure plate being movably fixed at the other end, the cantilever shafts on adjacent support plates being staggered in height, and the staggered height being sufficient to ensure that the electrode rolls suspended thereon are separated, and the welding bracket is sealed with an aluminum foil cover and then vacuumed.
[0007] Furthermore, the welding bracket is L-shaped and includes a base plate, a height plate, and a reinforcing plate. The height plate is vertically fixed to one side of the base plate, and its two ends are welded to the base plate through the reinforcing plate. Both the base plate and the height plate are frame structures formed by welding multiple square tubes.
[0008] Furthermore, a connecting plate is fixed on the height plate at each cantilever shaft connection point, and the cantilever shaft is fixedly connected to the connecting plate.
[0009] Furthermore, the base plate has multiple positioning platforms fixed on the top of the side away from the height plate. The positioning platforms are arranged in pairs and opposite to each other. Each support plate is embedded in the bottom of each group of positioning platforms and fixed with bolts to the positioning platforms.
[0010] Furthermore, a nine-legged tray is fixed to the bottom of the welding bracket.
[0011] Furthermore, the limiting baffle has a central opening to be fitted and fixed inside the cantilever shaft, and its periphery has a uniformly spaced fan-shaped hole structure.
[0012] Furthermore, the tightening pressure plate has a central opening to be fitted and fixed to the outside of the cantilever shaft, and one end of the cantilever shaft near the support plate is exposed and passes through the tightening pressure plate.
[0013] Furthermore, the tightening pressure plate is a circular cover structure with an outward extension on all four sides, and its interior has a stepped structure to be recessed and recessed into the outer end of the cantilever shaft. Multiple sets of tightening handles are also fixed around the outer periphery of the tightening pressure plate.
[0014] Furthermore, bearing rollers are fixed at equal intervals along the axial direction on the outer wall of the cantilever shaft.
[0015] Furthermore, the aluminum foil cover is a cardboard box structure, with a single-sided aluminum foil paper on the bottom surface to be placed at the bottom of the welding bracket in advance, and aluminum foil paper covering the top five sides to be heat-sealed with the bottom aluminum foil paper. The aluminum foil cover also has a vacuum port for vacuuming.
[0016] Compared with the prior art, the beneficial effects of this utility model include: the overall support of multiple electrode rolls is achieved by welding brackets, and in order to reduce the space required for transportation, the two cantilever shafts used to suspend the electrode rolls are spatially misaligned in height, so that the electrode rolls do not interfere with each other after placement, and are then sealed and evacuated with aluminum foil covers. Compared with the original all-metal sealed box, the cost is lower, the transportation process is more stable, and the efficiency is higher. Under the premise of meeting the transportation requirements, the structural cost is only 10% of that of the all-metal fully welded sealed box, and the unloaded weight is only 30% of that of the all-metal fully welded sealed box.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.
[0025] like Figure 1 As shown, in this embodiment, a long-distance truck transport device for small-rolled electrode sheets includes: a welding bracket 1, at least two support plates 2 vertically fixed to the top of the welding bracket 1, a cantilever shaft 3 horizontally fixed to the top of each support plate 2, one end of the cantilever shaft 3 away from the support plate 2 being fixedly connected to the welding bracket 1, a limit baffle 4 coaxially fixed to one end of each cantilever shaft 3 away from the support plate 2, and a tightening pressure plate 5 movably fixed to the other end, the cantilever shafts 3 on adjacent support plates 2 being staggered in height, and the staggered height is sufficient to ensure that the electrode sheets suspended on each are separated, and the welding bracket 1 is sealed with an aluminum foil cover and then vacuumed.
[0026] As can be seen from the above structure, in this solution, the overall support of multiple electrode rolls is achieved by welding bracket 1. In order to reduce the space required for transportation, the two cantilever shafts 3 used to suspend the electrode rolls are spatially misaligned in height. After the electrode rolls are placed, they do not interfere with each other. In addition, the aluminum foil cover is used for overall sealing and evacuation. Compared with the original all-metal sealed box, the cost is lower, the transportation process is more stable, and the efficiency is higher.
[0027] The following provides a more detailed description of the specific selection of each structural component in the scheme. In this embodiment, the welding bracket 1 is L-shaped and includes a base plate 6, a height plate 7, and a reinforcing plate 8. The height plate 7 is vertically fixed to one side of the base plate 6, and its two ends are welded to the base plate 6 through the reinforcing plate 8. Both the base plate 6 and the height plate 7 are frame structures formed by welding multiple square tubes.
[0028] Furthermore, a connecting plate 9 is fixed on the height plate 7 at each connection point of the cantilever shaft 3, and the cantilever shaft 3 is fixedly connected to the connecting plate 9. A plurality of positioning platforms 10 are fixed on the top of the base plate 6 on the side away from the height plate 7. The positioning platforms 10 are arranged in pairs and opposite to each other. Each support plate 2 is embedded in the bottom of each group of positioning platforms 10 and fixed to the positioning platform 10 with bolts.
[0029] To further improve the stability of the welding bracket 1 during transport, this solution also includes a nine-legged tray 11 fixed to the bottom of the welding bracket 1. The nine-legged tray 11 is a conventionally used plastic tray with nine legs, and metal square tubing is embedded in its nine plastic legs to enhance support strength. The hollow design makes it less prone to shaking during transport.
[0030] For the support and suspension of the pole roll, the limiting baffle 4 has a central opening to be fitted and fixed inside the cantilever shaft 3. The 140mm through hole in the center of the limiting baffle 4 is used to fit and fix the cantilever shaft 3 to the welding bracket 1. To reduce the structural weight, a fan-shaped through hole structure is designed evenly around its circumference. When in use, the limiting baffle 4 needs to be pushed into the inner side of the cantilever shaft 3 before the small roll of material is pushed in. The tightening pressure plate 5 has a central opening to be fitted and fixed outside the cantilever shaft 3. The end of the cantilever shaft 3 near the support plate 2 is exposed and passes through the tightening pressure plate 5. The tightening pressure plate 5 is a circular cover structure with outward extension on all four sides. The tightening pressure plate 5 is designed with a central through hole for fitting onto the outside of the cantilever shaft 3. The protruding part of the outer end of the cantilever shaft 3 passes through the through hole of the tightening pressure plate 5. At the same time, the tightening pressure plate 5 is designed as a circular cover with outward extension on all four sides. Its internal step design is in concave-convex interlocking with the step at the outer end of the cantilever shaft 3. The male step protrudes and cooperates with the tightening pressure plate 5. The outer diameter of the cantilever shaft 3 is smaller than the outer diameter of the tightening pressure plate 5 to prevent large-scale movement of the upper coil of the cantilever shaft 3. The tightening pressure plate 5 is also surrounded by multiple sets of tightening handles 12 for the operator to hold.
[0031] Similarly, the outer wall of the cantilever shaft 3 is fixed with bearing rollers 13 at equal intervals along its axial direction. The bearing rollers 13 are connected with a spacing of 50mm to reduce the friction force when the pole roll is pushed in.
[0032] For the overall sealing of the welding bracket 1 after loading the electrode roll, the aluminum foil cover used in this solution is a six-sided cardboard box inside, covered with six-sided aluminum foil on the outside. The six-sided aluminum foil is one side at the bottom and five sides at the top. After covering, the four sides of the splice are heat-sealed with heat-sealing clips in two parts, leaving a vacuum port. When using it, the six sides of the cardboard box inside need to cover the welding bracket 1. Aluminum foil is placed at the bottom in advance, and then the top five sides of aluminum foil are put on. After sealing the four sides of the aluminum foil with a heat-sealing gun, the air inside can be extracted from the vacuum port.
[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
