Description

Technical Field

[0001] This utility model relates to the field of fiber products technology for new energy vehicles, specifically a heating device for fiber products on the surface of battery box covers for new energy vehicles. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle industry is experiencing rapid growth. New energy vehicles, with their zero or low emissions, are gradually becoming the mainstream development direction of the automotive industry. As a core component of new energy vehicles, the performance and safety of the battery system are crucial. The battery cover, as an important part of the battery system, directly affects battery protection and overall vehicle performance. Fiber products are widely used in the manufacturing of battery covers for new energy vehicles. Fiber products possess advantages such as high strength, lightweight, good insulation properties, and corrosion resistance, which can effectively improve the overall performance of the battery cover while reducing vehicle weight and increasing the driving range of new energy vehicles.

[0003] Existing heating devices for fiber products fail to effectively remove impurities such as dust, oil, and metal particles from the surface of the fiber products before the heating process. These foreign objects not only adhere to the fiber surface but may also embed themselves within the material, disrupting the uniformity of the fiber structure. During heating, these impurities significantly interfere with heat conduction, leading to localized hot or cold spots with abnormal temperatures, directly affecting the overall heating effect of the product. Simultaneously, the presence of impurities weakens the bonding force between material interfaces, causing defects such as delamination and bubbles, resulting in insufficient product strength. Based on this background, designing a heating device for fiber products on the surface of battery box covers for new energy vehicles can effectively solve the problem of existing heating devices failing to effectively remove impurities before heating, and has significant practical implications.

[0004] The purpose of this utility model is to provide a heating device for fiber products on the surface of battery box covers of new energy vehicles, and to solve the following technical problems:

[0005] The objective of this utility model can be achieved through the following technical solution: A heating device for fiber products on the surface of a battery box cover for new energy vehicles, comprising a heating box, a fixed frame rotatably mounted in the middle of the heating box, a heating component slidably mounted at the bottom of the heating box, the heating component being used to reciprocate and heat the fiber product, a cleaning component slidably mounted at the upper end of the heating box, the cleaning component including a hydraulic telescopic rod slidably mounted inside the heating box, a U-shaped frame fixedly mounted at the lower end of the hydraulic telescopic rod, multiple brushes evenly spaced below the U-shaped frame, a vacuum cleaner mounted on one side of the U-shaped frame, and multiple vacuum heads evenly spaced at the lower end of the vacuum cleaner.

[0007] As a further embodiment of this utility model: a sliding assembly is provided at the upper end of the heating box, the sliding assembly includes a first slider that is slidably disposed at the upper end of the heating box, a connecting rod is fixedly disposed at the lower end of the first slider, and the lower end of the connecting rod is fixedly connected to a hydraulic telescopic rod.

[0009] As a further embodiment of this utility model: the two ends of the fixing frame are provided with rotating components, which are used to realize the rotation of the fixing frame. Vertical plates are fixedly provided on both sides of the upper end of the fixing frame. A groove is opened on the inner side of one of the vertical plates. Multiple moving rods are slidably sleeved through the groove at one end of the vertical plate. The same baffle is fixedly provided at one end of the multiple moving rods. An elastic element fixed between the groove and the baffle is sleeved on the moving rod. A cylinder is provided on the outer side of the other vertical plate.

[0012] As a further embodiment of this utility model, a guide plate is fixedly provided at the upper end of the heating box.

[0013] The beneficial effects of this utility model are:

[0014] (1) The bottom of the heating box of this utility model is slidably provided with a second slider. The second slider drives the heating tube to move back and forth, so as to uniformly heat the fiber products on the upper end of the fixed frame, so as to avoid the large local temperature difference and the mechanical properties of the fiber products change. The first slider at the upper end of the heating box drives the hydraulic telescopic rod to move back and forth. The hydraulic telescopic rod is used to adjust the distance between the brush and the dust suction head and the fiber products to meet the heating requirements of fiber products of different thicknesses. The reciprocating brush cleans the surface of the fiber products, and the vacuum cleaner simultaneously adsorbs the residual dust, forming an integrated cleaning of sweeping and dust removal, effectively eliminating impurities on the surface of the fiber products, avoiding the phenomenon of local temperature difference in the fiber products due to the presence of impurities, thereby effectively avoiding quality defects such as warping, bubbles and delamination on the surface of the fiber products.

The rotating component drives the rotation of the fixing frame, which facilitates the quick cleaning of the upper and lower ends of the fiber products and improves work efficiency. At the same time, when the rotating fixing frame is heated, the heating tube at the bottom of the heating box and the arc-shaped guide plate at the top can ensure that the surface and edge or complex structure of the fiber products at the top of the fixing frame can be covered with a stable heat flow, which significantly improves heating efficiency and reduces energy consumption.

[0029] In the field of fiber product technology, the problem of residual impurities on the surface of fiber products before heating and drying in new energy vehicle battery box covers has a significant impact on the quality of fiber products. A series of innovative designs have been implemented to achieve efficient removal of impurities from the surface of fiber products. The specific implementation methods are as follows:

[0030] like Figures 1-2As shown, a heating device for fiber products on the surface of a battery box cover for new energy vehicles includes a heating box 1. A fixing frame 2 is rotatably arranged in the middle of the heating box 1. The fixing frame 2 is used to clamp and fix the fiber products to complete subsequent cleaning and heating processes. A heating component 3 is slidably arranged at the bottom of the heating box 1. The heating component 3 is used to reciprocate and slide to uniformly heat the fiber products on the surface of the battery box cover for new energy vehicles. A cleaning component 4 is slidably arranged at the upper end of the heating box 1. The cleaning component 4 is used to clean and remove dust from the upper and lower surfaces of the fiber products. Dust, particles or fiber debris adhering to the surface of the fiber products may increase local thermal resistance due to high-temperature sintering during the heating process, resulting in uneven heating, which in turn causes inconsistent curing of the resin matrix, producing defects such as warping, bubbles or delamination, and reducing the processing quality of the product. The cleaning assembly 4 includes a hydraulic telescopic rod 41 slidably disposed inside the heating box 1. The hydraulic telescopic rod 41 is used to adjust its height to accommodate the cleaning needs of fiber products of different thicknesses. A U-shaped frame 42 is fixedly mounted on the lower end of the hydraulic telescopic rod 41. Multiple brushes 43 are evenly spaced below the U-shaped frame 42. A vacuum cleaner 44 is mounted on one side of the U-shaped frame 42. One end of the vacuum cleaner 44 is connected to a suction pipe 45 via a conduit. Multiple suction heads 46 are evenly spaced on the lower end of the suction pipe 45. The two sides of the fixed frame 2... Both ends of the heating box 1 have a certain space on both sides to place the cleaning component 4 after cleaning, so as to avoid interference between the cleaning component 4 and the rotating fixed frame 2. The suction head 46 is angled downward to facilitate the adsorption of free dust on the surface of the fiber product, ensuring that there is no residue on the surface of the fiber product. The brush 43 mechanically peels away loose debris and larger particles on the fiber surface, loosens the deeply attached dust, and provides a better cleaning effect for the subsequent vacuum cleaner 44. The vacuum cleaner 44 removes the fine dust remaining after the brush 43 treatment by negative pressure suction.

[0031] like Figures 3-4As shown, an elastic component 47 is fixedly installed at the lower end of the U-shaped frame 42. The elastic component 47 includes multiple extrusion columns 471 fixedly installed at the lower end of the U-shaped frame 42. In this embodiment, there are three extrusion columns 471. The lower end of each extrusion column 471 is slidably sleeved with an extrusion sleeve 472. A pressing spring 473 is sleeved on the upper surface of each extrusion column 471. The pressing spring 473 is located inside the extrusion sleeve 472. The upper end of the pressing spring 473 is fixedly connected to the upper inner end of the extrusion sleeve 472. The lower end of the pressing spring 473 is fixedly connected to the extrusion column 471. After the hydraulic telescopic rod 41 is initially adjusted, the pressing spring 473 drives the extrusion sleeve 472 to make fine adjustments. The compression amount of the extrusion sleeve 472 will automatically adjust according to the thickness of the fiber product. Under the action of the spring, the extrusion column 471 dynamically adapts to fiber materials of different thicknesses or fluffiness, avoiding uneven pressure distribution when the brush 43 contacts the fiber due to uneven material, thus resulting in poor cleaning quality. The lower ends of the plurality of extrusion sleeves 472 are fixedly provided with the same horizontal plate 48, and the lower ends of the horizontal plate 48 are fixedly connected to the plurality of brushes 43.

[0032] like Figure 5 As shown, a sliding assembly 5 is provided at the upper end of the heating box 1. The sliding assembly 5 includes a first servo motor 51 fixedly installed at one end of the heating box 1. A first lead screw 52 is provided on the output shaft of the first servo motor 51. The length of the first lead screw 52 is greater than the length of the fixed frame 2.

[0033] The first lead screw 52 is threadedly connected to the first slider 53. The lower end of the first slider 53 is fixedly provided with a connecting rod 54. The two ends of the first slider 53 are provided with limit rods. The limit rods are used to limit the rotation of the first slider 53. The lower end of the connecting rod 54 is fixedly connected to the hydraulic telescopic rod 41. Driven by the first servo motor 51, the first lead screw 52 drives the first slider 53 to move back and forth, thereby driving the brush 43 and the vacuum head 46 at the lower end to reciprocate to clean the surface of the fiber product, avoiding cleaning dead corners.

[0034] During use, the first slider 53 drives the connecting rod 54 to move back and forth, thereby driving the brush 43 and the vacuum head 46 to move back and forth to clean the surface of the fiber product. The brush 43 mechanically peels away loose debris and larger particles from the fiber surface, loosening deeply attached dust. Then, the vacuum cleaner 44 uses negative pressure to remove the fine dust remaining after the brush 43 has been processed. During the movement of the U-shaped frame 42, the pressing spring 473 drives the squeezing sleeve 472 to move down, thereby ensuring that the brush 43 at the lower end of the horizontal plate 48 always keeps in contact with the surface of the fiber product, improving the cleaning quality and avoiding the phenomenon of local temperature difference in the fiber product due to the presence of impurities. This effectively avoids quality defects such as warping, bubbles, and delamination on the surface of the fiber product. After cleaning both sides of the fiber product, the cleaning component 4 is moved to one end of the heating box 1 to avoid motion interference between the cleaning component 4 and the rotating fixed frame 2.

[0035] like Figure 1 As shown, the heating assembly 3 includes fixed blocks 31 symmetrically arranged at the bottom of the heating box 1. A second lead screw 32 is rotatably arranged between the two fixed blocks 31. One end of the second lead screw 32 is connected to a second servo motor 33. The end of the second servo motor 33 away from the second lead screw 32 is connected to the fixed block 31. The output shaft of the second servo motor 33 is connected to the second lead screw 32. A second slider 34 is threadedly connected to the outer surface of the second lead screw 32. A heating tube 35 is fixedly connected to the top of the second slider 34. The upper end of the heating tube 35 is provided with multiple air outlets. High-temperature airflow is output through the air outlets to evenly blow on the fiber surface and conduct heat. An air inlet 36 is provided at one end of the heating tube 35.

[0036] During heating, a high-temperature hot airflow enters from the air inlet 36 and exits from the air outlet at the upper end of the heating tube 35, heating the fiber products. The heating tube 35 moves back and forth to heat the surface, so that the heat source dynamically covers the entire working surface, avoiding uneven heating caused by fixed heating, thereby significantly improving the uniformity of heating and improving the processing quality of fiber products on the surface of new energy vehicle battery box covers.

[0037] The bottom of the heating box 1 is provided with a sliding groove 37. The second slider 34 is slidably engaged in the sliding groove 37. The sliding groove 37 restricts the rotation of the second slider 34, so that the second slider 34 moves horizontally reciprocally under the drive of the second lead screw 32.

[0038] like Figures 6-7As shown, the fixed frame 2 is provided with rotating components 6 at both ends. The rotating components 6 are used to realize the rotation of the fixed frame 2. Vertical plates 71 are fixedly provided on both sides of the upper end of the fixed frame 2. A groove 72 is opened on the inner side of one of the vertical plates 71. Multiple moving rods 73 are slidably sleeved on one end of the vertical plate 71 through the inside of the groove 72. The same baffle 74 is fixedly provided on one end of the multiple moving rods 73. An elastic element 75 is sleeved on the moving rod 73 and fixed between the groove 72 and the baffle 74. The elastic element 75 can be a spring. The moving rod 73 is used to guide the baffle 74 and prevent the elastic element 75 from tilting downward, so that the baffle 74 tilts downward.

[0039] Another vertical plate 71 is provided with a cylinder 76 on its outer side. The end of the cylinder 76 passes through the vertical plate 71 and is connected to an extrusion plate 77. The cylinder 76 drives the extrusion plate 77 to move back and forth to accommodate the clamping and fixing of fiber products of different sizes.

[0040] like Figure 8 As shown, the rotating assembly 6 includes an active disk 61 disposed inside a protective box on one side of the heating box 1. The active disk 61 is rotated by a drive motor disposed inside the protective box. A driven disk 62 connected to the heating box 1 is disposed at the upper end of the active disk 61. A transmission rod 63 is fixedly connected to the central axis of the driven disk 62. One end of the transmission rod 63 passes through the side wall of the heating box 1 and is fixedly connected to the fixed frame 2. The transmission rod 63 is rotatably sleeved with the heating box 1. The distance between the central axis of the fixed frame 2 and the upper, lower and front and rear sides of the heating box 1 exceeds the rotation radius of the fixed frame 2 to ensure that there is no interference with the heating box 1 when the fixed frame 2 rotates.

[0041] The drive motor rotates the active disc 61, which in turn rotates the driven disc 62, precisely adjusting the angle of the fixed frame 2. During cleaning, the precise control of the angle of the fixed frame 2 ensures accurate positioning of the fiber products during cleaning or heating, avoiding cleaning dead corners caused by deviations. No manual adjustment is required, reducing human intervention and improving cleaning efficiency. During heating, the intermittent rotation of the fixed frame 2 ensures uniform heating of the fiber products, avoiding local overheating or underheating (such as hot air penetrating different areas), thus improving the processing quality.

[0042] When the heating device is working, firstly, the drive motor drives the active disk 61 to rotate, thereby driving the driven disk 62 to rotate, so as to realize the rapid flipping of the fiber product and quickly clean and adsorb the upper and lower surfaces of the fiber product. During heating, the heating tube 35 at the bottom of the heating box 1, together with the arc-shaped guide plate 9 at the top, can ensure that the surface, edge or complex structure of the fiber product on the upper end of the fixing frame 2 can obtain a stable heat flow coverage, which significantly improves heating efficiency and reduces energy consumption.

[0043] like Figure 2, Figure 5 As shown, a hot air blower 8 is installed at the rear end of the heating box 1. A conveying pipe is provided on the outside of the hot air blower 8. The conveying pipe passes through the rear end of the heating box 1 and is connected to the air inlet 36. The conveying pipe is an extendable flexible hose, which allows the conveying pipe to move back and forth with the heating pipe 35 without being damaged, ensuring a continuous output of hot air. A guide plate 9 is fixedly installed at the upper end of the heating box 1. The guide plate 9 is arc-shaped and can guide the hot air to flow downwards to achieve secondary heating. This ensures that the edges or complex structural parts of the fiber products can be covered with a stable heat flow, significantly improving heating efficiency and reducing energy consumption.

[0044] In summary, a heating device for fiber products on the surface of a battery box cover for new energy vehicles, in use, firstly, the sliding component 5 drives the brush 43 and the vacuum head 46 to perform integrated cleaning and dust removal on the surface of the fiber product, effectively eliminating impurities on the surface of the fiber product. The rotating component 6 drives the fiber product on the upper end of the fixed frame 2 to rotate, realizing cleaning of both the upper and lower surfaces of the fiber product, improving work efficiency. After cleaning, the brush 43 and the vacuum head 46 are moved to one end of the heating box 1, and the rotating component 6 drives the fiber product to rotate slowly. At the same time, the heating tube 35 slidably installed at the bottom of the heating box 1 heats the fiber product. The heating tube 35, together with the arc-shaped guide plate 9 at the upper end, can ensure that the surface, edges, or complex structural parts of the fiber product on the upper end of the fixed frame 2 can obtain stable heat flow coverage, significantly improving heating efficiency and reducing energy consumption.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
