Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to an integrated edge-wrapping device for charging ports. Background Technology

[0002] With the rapid development of the new energy industry, the safety and precision requirements of charging equipment are increasing. The charging port, as a key interface for energy transmission, directly affects the sealing, conductivity, and lifespan of the equipment due to the quality of its edge processing. Charging port components are typically made of metal or high-strength plastic, requiring edge-wrapping processes to achieve smooth edge transitions, scratch prevention, and sealing protection. This places stringent demands on the positioning accuracy, drive stability, and molding consistency of the processing equipment.

[0003] For related technology, please refer to announcement number CN113070685B, which discloses an integrated mold for edge banding and spot welding, including an edge banding mold and a spot welding assembly. The edge banding mold includes an upper edge banding module and a lower edge banding module, and the spot welding assembly includes an upper spot welding module and a lower spot welding module. The upper spot welding module is connected to the upper edge banding module, and the lower edge banding module has an accommodating groove. The lower spot welding module is installed in the accommodating groove. The upper spot welding module is provided with an upper electrode head, and the lower spot welding module is provided with a lower electrode head. An accommodating space for placing a workpiece is formed between the upper electrode head and the lower electrode head. The upper edge banding module can be lowered or raised relative to the lower edge banding module to correspondingly close or open the mold with the upper edge banding module and to correspondingly move the upper electrode head closer to or away from the lower electrode head.

[0004] The application scenarios and structural design of the aforementioned devices are completely inadequate to cover the edge-wrapping requirements of charging ports. Specifically, their overall structure is designed around the size and function of large vehicle doors and tailgates. For example, the upper electrode head is arranged at intervals along the circumference of the mounting platform, and the lower electrode head is located on the annular flange. It also integrates complex components such as cooling channels and nitrogen spring pre-compression mechanisms, making it only suitable for processing large components. However, as a small-sized, irregularly shaped component, the charging port can meet strength requirements without spot welding. The spot welding-related components in existing technologies are redundant designs and cannot be directly applied to the edge-wrapping of charging ports. Furthermore, the industry lacks dedicated edge-wrapping devices for charging ports, resulting in current edge-wrapping of charging ports relying on manual labor, which leads to problems such as difficult operation, low efficiency, and unstable quality.

[0005] To address the aforementioned issues, this utility model proposes an integrated edge-wrapping device for charging ports that is simple in structure, low in cost, and easy to operate, in order to meet the mass production processing requirements of electric vehicle charging ports. Utility Model Content

[0006] To address the shortcomings of the existing technology and improve the efficiency of edge wrapping for electric vehicle charging ports, this application provides an integrated edge wrapping device for charging ports.

[0020] Optionally, the drive unit may be an electromagnetic lock or a cylinder lock.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This invention achieves precise positioning and clamping of the charging port workpiece through multiple positioning mechanisms in the support structure; the horizontal and vertical driving mechanisms of the drive unit enable controllable movement of the edge-wrapping execution component in both horizontal and vertical directions; the detachable edge-wrapping forming structure in the edge-wrapping execution component, adapted to the contour of the charging port, can precisely match the workpiece contour.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses an integrated edge-wrapping device for charging ports.

[0029] Reference Figure 1 A charging port integrated edge-wrapping device includes a base 1, a support mechanism 2, a drive unit 3, and an edge-wrapping execution component.

[0030] Reference Figure 1Support mechanism 2: Located on base 1, including multiple positioning mechanisms for positioning and clamping the charging port workpiece to be processed; Drive unit 3: Includes horizontal moving mechanisms located on both sides of base 1. The horizontal moving mechanism includes two sets of parallel slide rails 301. A vertical drive mechanism is provided on the slide rails 301. The vertical drive mechanism includes a gantry frame 302 with a frame structure. The two sets of columns of the gantry frame 302 are slidably connected to the two sets of slide rails 301 respectively. A drive cylinder 303 is fixedly provided on the crossbeam of the gantry frame 302. The output end of the drive cylinder 303 extends and retracts vertically through the crossbeam of the gantry frame 302; Edge wrapping execution component: Includes an extension rod 4 connected to the output end of the drive cylinder 303. The end of the extension rod 4 is detachably fixed with an edge wrapping forming structure 5 adapted to the outline of the charging port. The base 1 provides an installation reference; the support mechanism 2 uses multiple positioning mechanisms to position and clamp the workpiece to be processed, solving the basic problem of easy deviation of the workpiece during processing; the drive unit 3 adjusts the horizontal position of the vertical drive mechanism through the horizontal moving mechanism on both sides of the base 1, and then the drive cylinder 303 drives the edge wrapping execution component to move in the vertical direction, realizing the position adjustment and power output of the edge wrapping action; the edge wrapping execution component ensures that the edge wrapping contour matches the workpiece through the detachable edge wrapping forming structure 5 adapted to the outline of the charging port.

[0031] Reference Figure 1 and Figure 2 The positioning mechanism includes: a positioning seat 201, with a positioning groove and positioning pin on its surface adapted to the shape of the workpiece for the charging port; and a clamping assembly 202, which is a pneumatic gripper or hydraulic clamp used to lock the workpiece in the positioning seat 201. The positioning seat 201, through the positioning groove and positioning pin adapted to the shape of the workpiece for the charging port, achieves pre-positioning of the workpiece, ensuring accurate initial placement; the clamping assembly 202 then locks the pre-positioned workpiece in the positioning seat 201, preventing the workpiece from loosening during processing.

[0032] Reference Figure 1 and Figure 2 The clamping components 202 are symmetrically distributed along the circumference of the positioning seat 201, and at least two sets are provided. The circumferential symmetrical distribution can make the clamping force act evenly on the circumference of the workpiece, avoiding workpiece deformation or displacement caused by asymmetrical clamping. The design of at least two sets can ensure the redundancy of the clamping force and prevent workpiece loosening caused by the failure of a single clamping component 202.

[0033] Reference Figure 1 and Figure 2 A triangular fixing frame 6 is fixed below the crossbeam of the gantry frame 302 to cooperate with the extension rod 4. The triangular fixing frame 6 is slidably connected to the extension rod 4. The triangular fixing frame 6 uses the structural stability of the triangle to provide radial support and vertical guidance for the extension rod 4, so as to avoid shaking or deviation when the drive cylinder 303 drives the extension rod 4 to move vertically.

[0034] Reference Figure 1 and Figure 2 The edge-wrapping forming structure 5 includes a connecting block 501 fixedly connected to the extension rod 4 and an edge-wrapping module 502 detachably connected to the connecting block 501. The lower end face of the edge-wrapping module 502 is provided with a forming cavity that matches the edge-wrapping contour of the charging port. The connecting block 501 is fixedly connected to the extension rod 4. The detachable edge-wrapping module 502 can be quickly replaced according to the different processes of stamping the charging port workpiece to meet the edge-wrapping contour requirements and quickly replace the appropriate forming cavity.

[0035] Reference Figure 1 and Figure 2 The edge-binding mold is made of cemented carbide or heat-treated alloy steel. The surface of the forming cavity is coated with a wear-resistant coating. The cemented carbide / heat-treated alloy steel has high strength and high hardness, and can withstand the extrusion pressure during edge-binding without easily deforming. The wear-resistant coating can reduce the friction wear between the forming cavity and the workpiece and extend the service life of the mold.

[0036] Reference Figure 1 and Figure 2 A limiting plate 7 is fixedly installed on the side wall of the extension rod 4 away from the triangular fixing frame 6. Multiple sets of limiting holes 8 are spaced apart along the vertical direction on the limiting plate 7. A locking mechanism 9 is also included: the locking mechanism 9 is fixedly connected to the lower side of the crossbeam of the gantry frame 302, including a connecting seat 901 and a driving component 902. The driving component 902 uses an electromagnetic lock or a cylinder lock. The output end of the driving component 902 can be driven to extend and insert into the limiting hole 8 of the extension rod 4 corresponding to the position of the locking mechanism 9. The multiple sets of limiting holes 8 on the limiting plate 7 can preset the vertical movement stroke of the extension rod 4 to correspond to different edge-binding depth requirements. The locking mechanism 9 can lock the extension rod 4 at the preset stroke position, preventing displacement of the extension rod 4 caused by accidental operation of the driving cylinder 303. Simultaneously, when not in use, it is inserted into the limiting hole 8 of the extension rod 4, reducing the workload of the driving cylinder 303 and improving the service life of the device.

[0037] Reference Figure 1 and Figure 2 The base 1 is equipped with a leveling cup 10 at the bottom, which is used to adjust the levelness of the device. The leveling cup 10 can adjust the height of one foot to keep the base 1 level on the uneven mounting surface, so as to avoid the relative position deviation of the support mechanism 2, drive unit 3 and edge-wrapping execution component due to the tilt of the base 1.

[0038] The working principle of the integrated charging port edge-wrapping device in this application embodiment is as follows: The base 1 serves as the bearing base and installation reference of the device, providing a stable installation reference surface for the support mechanism 2, the drive unit 3, and the edge-wrapping execution component; the leveling cup 10 provided at its bottom, through the single-leg height adjustable design, can calibrate the levelness of the base 1 on uneven installation surfaces, thus establishing a precision reference for the device's operation from the source; based on this reference, the support mechanism 2 completes the precise holding of the charging port workpiece to be processed through multiple sets of positioning mechanisms: the positioning seat 201 utilizes a profile adaptation structure and pin hole positioning structure adapted to the workpiece shape to achieve the initial pre-positioning of the workpiece, ensuring the accurate placement of the workpiece; the clamping components 202, symmetrically distributed around the positioning seat 201, lock the workpiece in the positioning seat 201 with a uniform clamping force after pre-positioning, preventing the workpiece from shifting or deforming due to force during processing; after the workpiece is precisely held, the drive unit 3 adjusts the position of the edge-wrapping execution component and provides it with motion power; the edge-wrapping execution component receives the power output of the drive unit 3, completes the edge-wrapping forming action, and achieves multi-specification adaptation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
