Description

Technical Field

[0001] The present invention relates to the technical field of electrophoresis of automobile parts, and in particular to an electrophoresis suspension and fixing system for battery pack shell components of new energy vehicles. Background Art

[0002] Before assembly, new energy vehicle battery pack shell components usually require an electrophoretic process. Under the action of an electric field, charged particles are deposited on the surface of the shell components to form a uniform, dense coating with a certain thickness, effectively preventing the shell components from corrosion in hot and humid environments and high salt fog environments, thereby extending their service life.

[0003] In the prior art, the entire electrophoresis production line is equipped with a hanging conveyor system at the top. C-shaped hooks are distributed on the hanging conveyor system, and the shell components are mainly fixed and hung by wire. However, this traditional fixing method has the following problems:

[0004] 1. Poor stability: The wire hanging method is difficult to ensure the firm fixation of the shell components. It is easy to shake or even fall off when the hanging conveying system moves or the electrophoresis tank liquid flow impacts, making it difficult to ensure the product yield.

[0005] 2. Easy to damage the workpiece: The contact area between the wire and the shell components may scratch the surface of the workpiece during the lifting or electrophoresis process, affecting the coating quality and increasing the rework cost.

[0006] 3. Inconvenient operation: Manual tying of wire is inefficient and difficult to achieve standardized operations, which increases the labor intensity and production time costs of workers. Summary of the Invention

[0007] In view of this, the present invention provides an electrophoretic suspension and fixing system for battery pack shell components of new energy vehicles, aiming to solve the problems existing in the background technology.

[0008] To achieve the above purpose, the technical solution of the present invention is as follows:

[0009] An electrophoretic suspension and fixing system for battery pack shell components of new energy vehicles includes a suspension conveying system with a suspension assembly provided below the suspension conveying system. The system is characterized in that at least two groups of hooks are provided at the lower portion of the suspension assembly, and the hooks are arranged at intervals along the width direction of the electrophoretic tank. A shell component is hung on each of the hooks, and a support frame is installed between the lower portions of two adjacent shell components.

[0010] With the above structure, at least two hooks are provided at the lower end of the suspension assembly, so that one suspension assembly can simultaneously hang multiple shell components, thereby ensuring the efficiency of electrophoresis of the shell components; and the support frame is provided so that two adjacent shell components can be stably supported, thereby avoiding collision between the two adjacent shell components during the electrophoresis process.

[0011] Preferably, the suspension assembly includes a mounting plate extending along the width of the electrophoresis tank. A connecting hook extending upward is provided in the middle of the mounting plate, which is attached to the suspension conveyor system. Two sets of these hooks are connected at either end of the mounting plate along its length. This structure, coupled with the mounting plate, enables the suspension assembly to simultaneously mount multiple housing components, thereby ensuring efficient electrophoresis. Furthermore, the mounting plate, support frame, and the rectangular structure formed between adjacent housing components further ensure stable mounting of the housing components.

[0012] Preferably, the hook includes an upper hanging part and a lower hanging part, the lower end of the upper hanging part has a first strip hole, the upper end of the lower hanging part has a second strip hole, the upper hanging part and the lower hanging part are locked together through the first strip hole and the second strip hole, and the hanging directions of the upper hanging part and the lower hanging part are perpendicular to each other in space. With the above structure, the upper hanging part and the lower hanging part are movably connected through the strip hole, ensuring smoother uphill and downhill climbing and turning during electrophoresis, while reducing the overall shaking of the suspension assembly; the hanging directions of the upper hanging part and the lower hanging part are vertically arranged in space, which can ensure that after the upper hanging part is hung on the mounting plate, the two shell components can be arranged in parallel, and the length direction of the shell component is parallel to the length direction of the electrophoresis tank, thereby reducing the driving resistance of the shell component during the electrophoresis process.

[0013] Preferably, the first strip-shaped hole has a first toothed portion at its lower end, and the second strip-shaped hole has a second toothed portion at its upper end. When the hook is mounted on the mounting plate, the first and second toothed portions abut against each other. With this structure, if electrophoretic paint accumulates and blocks the strip-shaped hole, the toothed portions can pierce the paint, thereby preventing poor electrical conductivity caused by electrophoretic paint accumulation.

[0014] Preferably, the mounting plate is formed with five hanging holes, one of which is formed in the middle of the mounting plate, and the remaining four are symmetrically distributed at both ends of the mounting plate. The upper hanging portion is mounted within these hanging holes. This structure allows the mounting plate to be mounted with a corresponding number of hooks for housing components of different sizes and models, increasing the versatility of the mounting plate. Furthermore, the mounting plate can simultaneously mount multiple housing components, improving the electrophoresis efficiency of the housing components.

[0015] Preferably, the connecting hook, upper hanging portion, and lower hanging portion all have rectangular cross-sections, and the hanging hole is configured as an inverted trapezoidal structure. This rectangular design increases the contact area between the connecting hook, upper hanging portion, and lower hanging portion after installation, further preventing the hanging assembly from shaking after installation. The hook's inverted trapezoidal design also prevents shaking after installation.

[0016] Preferably, two suspension assemblies are provided on the top of the housing component along the length direction of the electrophoresis tank, and the two suspension assemblies are spaced apart and arranged below the suspension conveying system. With the above structure, the same housing component is hung by two suspension assemblies, which further ensures the stable hanging of the suspension assemblies.

[0017] Preferably, the support frame includes a support rod and a U-shaped frame fixed to each end of the support rod. Each end of the U-shaped frame has outwardly extending clips for supporting against the inner wall of the mounting hole in the housing component. With this structure, the clips support the inner wall of the mounting hole in the housing component, providing support between the two housing components and preventing collision or drift of the housing components during electrophoresis.

[0018] Preferably, both ends of the U-shaped frame further have inclined portions inclined inward, and the clamping portions are arranged at the ends of the inclined portions. The above structure ensures that after the support frame is installed, the two shell components will not be axially close to each other along the support rod.

[0019] As a preferred embodiment, the housing further comprises a counterweight block, which is mounted on the bottom of the housing component. The above structure can further prevent the housing component from drifting during the electrophoresis process.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The electrophoretic suspension and fixing system for battery pack shell components of new energy vehicles provided by the present invention uses at least two hooks provided at the lower end of the suspension assembly to enable one suspension assembly to simultaneously hang multiple shell components, thereby ensuring the efficiency of electrophoresis of the shell components; and the support frame is provided to ensure that two adjacent shell components can be stably supported, thereby avoiding collision between the two adjacent shell components during the electrophoresis process.

[0022] 2. The cross-section of each hook of the entire suspension assembly is set to a rectangular structure, which increases the contact area of ​​each hook after hanging and further ensures the stability of the hanging.

[0023] 3. The hanging directions of the upper hanging part and the lower hanging part are vertical in space, so that after the shell component is hung, its length side is parallel to the length direction of the electrophoresis tank, which helps to reduce the resistance encountered by the shell component when moving in the electrophoresis tank.

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, a suspension and fixation system for electrophoresis battery pack housing components for new energy vehicles includes a suspension conveyor system 7, with a suspension assembly disposed below the suspension conveyor system 7. In this embodiment, C-shaped hooks 8 are distributed along the length of the electrophoresis tank 10 on the suspension conveyor system 7, and the suspension assembly is suspended from the C-shaped hooks 8. At least two sets of hooks A are provided at the bottom of the suspension assembly. The hooks A are spaced apart along the width of the electrophoresis tank 10, and each hook A is mounted with a housing component 9. A support frame 3 is installed between the lower portions of two adjacent housing components 9.

[0035] With this design, at least two hooks A are provided at the lower end of the suspension assembly, so that one suspension assembly can simultaneously hang multiple shell components 9, thereby ensuring the electrophoresis efficiency of the shell components 9; and the support frame 3 is provided so that two adjacent shell components 9 can be stably supported, thereby avoiding collision between the two adjacent shell components 9 during the electrophoresis process.

[0036] In this embodiment, the shell component 9 is a battery box. Of course, according to different electrophoresis requirements, the shell component 9 can also be a bottom guard plate, a liquid cooling plate, a box cover or other shell-like components.

[0037] Further, such as Figure 2 As shown, the suspension assembly includes a mounting plate 2 extending along the width of the electrophoresis tank 10. An upward-extending connecting hook 1 is provided in the middle of the mounting plate 2. The connecting hook 1 is attached to the suspension conveyor system 7. Two sets of hooks A are connected to the mounting plate 2 at either end along its length. This design, through the installation of the mounting plate 2, enables the suspension assembly to simultaneously mount multiple housing components 9, thereby ensuring the electrophoresis efficiency of the housing components 9. Furthermore, the rectangular structure formed between the mounting plate 2, the support frame 3, and two adjacent housing components 9 further ensures stable mounting of the housing components 9.

[0038] like Figure 3 and Figure 4 As shown, the mounting plate 2 is a plate-like structure with a raised portion 2b at its upper end, converging from two sides toward the center. The lower end of the connecting hook 1 is welded to the upper end of the middle portion of the raised portion 2b. The plate-like structure makes the mounting plate 2 lighter, while the raised portion 2b prevents the mounting plate 2 from breaking in the middle due to the excessive weight of the housing component 9 mounted at the lower end of the mounting plate 2.

[0039] like Figures 5 to 8 As shown, the hook A includes an upper hanging portion 4 and a lower hanging portion 5. The lower end of the upper hanging portion 4 has a first strip hole 4a, and the upper end of the lower hanging portion 5 has a second strip hole 5a. The upper hanging portion 4 and the lower hanging portion 5 are locked together through the first strip hole 4a and the second strip hole 5a. The hanging directions of the upper hanging portion 4 and the lower hanging portion 5 are perpendicular to each other in space. With this design, the upper hanging portion 4 and the lower hanging portion 5 are movably connected through the strip hole, which can ensure that the shell component 9 can go up and down slopes and turn more smoothly during the electrophoresis process. The hanging directions of the upper hanging portion 4 and the lower hanging portion 5 are perpendicular to each other in space, which can ensure that after the hook A is hung on the mounting plate 2, the two shell components 9 can be arranged in parallel, and the length direction of the shell component 9 is parallel to the length direction of the electrophoresis tank 10, thereby reducing the driving resistance of the shell component 9 moving in the electrophoresis tank 10.

[0040] Furthermore, the lower end of the first strip hole 4a has a first tooth-shaped portion 4b, and the upper end of the second strip hole 5a has a second tooth-shaped portion 5b. After the hook A is hung on the mounting plate 2, the first tooth-shaped portion 4b and the second tooth-shaped portion 5b are pressed against each other. With such a design, when the electrophoretic paint accumulates and blocks the strip hole, the tooth-shaped portion can puncture the electrophoretic paint, thereby avoiding the accumulation of electrophoretic paint at the connection between the upper suspension portion 4 and the lower suspension portion 5 during the electrophoretic process, resulting in poor conductivity.

[0041] like Figure 7As shown, the mounting plate 2 is formed with five hanging holes 2a, one of which is formed in the middle of the mounting plate 2, and the remaining four hanging holes 2a are symmetrically distributed at both ends of the mounting plate 2. The upper hanging portion 4 is mounted in the hanging holes 2a. This design allows the mounting plate 2 to be mounted with a corresponding number of hooks A according to the different models and sizes of the housing components 9, increasing the versatility of the mounting plate 2. Furthermore, the mounting plate 2 can simultaneously mount multiple housing components 9, increasing the electrophoresis efficiency of the housing components 9.

[0042] In this embodiment, the number of the hanging holes 2 a formed on the mounting plate 2 is not limited to five, and is determined according to the specific model and size of the housing component 9 .

[0043] like Figure 4 As shown, the connecting hook 1 has an arcuate segment 1a. A first extension segment 1b extending vertically downward is provided at the end of the arcuate segment 1a away from the mounting plate 2, and a second extension segment 1c extending obliquely from the lower end of the first extension segment 1b. This design, with the two extension segments, effectively prevents the connecting hook 1 from detaching from the C-shaped hook 8 due to shaking of the suspension assembly during electrophoresis. In this embodiment, the specific structure of the upper suspension portion 4 is identical to that of the connecting hook 1, and will not be repeated here.

[0044] Furthermore, the cross-sections of the connecting hook 1, upper hanging portion 4, and lower hanging portion 5 are all rectangular. This design increases the contact area between the connecting hook 1, upper hanging portion 4, and lower hanging portion 5 after installation, thereby effectively reducing the wobble of the entire hanging assembly. In this embodiment, the hanging hole 2a is constructed as an inverted trapezoidal structure, further preventing the hook A from wobble after installation.

[0045] like Figure 1 As shown, two sets of suspension components are provided on the top of the housing part 9 along the length direction of the electrophoresis tank 10, and the two sets of suspension components are spaced apart below the suspension conveying system 7. By using the two sets of suspension components, one in front and one in the back, the housing part 9 can be further ensured to be stably hung.

[0046] like Figure 9 As shown, the support frame 3 includes a horizontally arranged support rod 3a and a U-shaped frame 3b fixed at each end of the support rod 3a. In this embodiment, the U-shaped frame 3b is fixed to the end of the support rod 3a by welding. The two ends of the U-shaped frame 3b have a clamping portion 3c extending outward. The clamping portion 3c is used to support the inner wall of the mounting hole in the shell component 9. During use, the two sides of the U-shaped frame 3b are pressed inward to bring the clamping portions 3c at both ends closer to each other. The end of the U-shaped frame 3b is then inserted into the mounting hole. Finally, the two sides of the U-shaped frame 3b are elastically rebounded to the sides, thereby causing the clamping portions 3c to abut against the inner wall of the mounting hole. This design can ensure that the ends of the support frame 3 are stably installed in the mounting hole of the shell component 9, thereby ensuring that the support frame 3 is stably supported between two adjacent shell components 9.

[0047] Furthermore, both ends of the U-shaped frame 3b also have inclined portions 3d inclined toward the inside, and the clamping portions 3c are formed at the ends of the inclined portions 3d. With such a design, after the support frame 3 is supported between the two shell components 9, during the electrophoresis process, the two shell components 9 will not approach each other axially along the support rod 4a.

[0048] For example Figure 1 and Figure 2 As shown, the electrophoretic suspension and fixing system for the shell components of the battery pack of new energy vehicles also includes a counterweight block 6, which is hung at the bottom of the shell component 9. Such a design can prevent some lighter shell components 9 from drifting during the electrophoresis process.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
