Description

Technical Field

[0001] This utility model relates to the field of charging port vehicle body panel processing technology, and in particular to a frame spraying tool. Background Technology

[0002] The charging port body panel typically refers to the body component on an electric vehicle related to the charging interface. Its main function is to protect the charging port and the surrounding area from interference or damage from external objects, while ensuring the safety and reliability of the charging process. The charging port body panel frame is a structural component in an electric vehicle related to the charging port, primarily responsible for supporting and protecting the external structure of the charging port and its surrounding area. This frame is usually made of metal or high-strength plastic and is designed to ensure effective protection of the charging port in the vehicle's external environment, and to withstand the impact of friction, collisions, and other external forces during daily use. The charging port frame also provides support for the charging port, ensuring a secure connection between the charging interface and the vehicle body, and preventing the charging port from loosening or shifting due to collisions or external forces. The frame helps protect the charging port from external physical damage, especially collisions or scratches; it acts as a "protective shield" for the charging port, preventing damage to the interface in the event of accidental impact or contact.

[0003] The frame design typically incorporates waterproof and dustproof features to ensure that the charging port remains functional even in harsh weather conditions (such as rain or dust). The frame also requires the use of high-strength materials such as aluminum alloy, steel, or engineering plastics to ensure structural stability over long-term use and to maintain a certain level of impact resistance during frequent use or collisions.

[0004] The charging port body panel is a non-fully insulated product. This means that during the bonding process between the panel frame and the rubber body, the frame is not completely encased in rubber. Therefore, the frame of the charging port body panel only needs adhesive applied to the contact areas with the rubber body. Traditional non-fully insulated products with frames typically use brushing or spraying to apply adhesive to the contact areas between the frame and the rubber body. During adhesive spraying, the adhesive tends to flow from the sprayed area (the upper surface of the frame) to the sides of the frame, exceeding the pre-set bonding area and causing excess adhesive during subsequent vulcanization. This excess adhesive needs to be manually removed, resulting in low processing efficiency, high cost, and inconsistent product yield. Utility Model Content

[0005] This utility model provides a skeleton spraying fixture, which can solve the problem mentioned in the background art that the adhesive easily flows from the spraying area to the side of the skeleton, causing the adhesive to exceed the preset bonding area and cause glue overflow.

[0006] A frame spraying fixture includes: a lower support plate and an upper cover plate, wherein the frame is disposed between the lower support plate and the upper cover plate, and is sealed and fixed by the lower support plate and the upper cover plate pressing against each other;

[0007] The upper cover plate has several spray holes to expose the bonding area of ​​the skeleton.

[0008] Preferably, the lower support plate is provided with several workstations, and the several workstations are distributed in an array.

[0009] Preferably, a separation gap is provided between two adjacent workstations.

[0010] Preferably, each of the spray holes corresponds one-to-one with one of the workstations.

[0011] Preferably, a rib is provided between two adjacent spray holes.

[0012] Preferably, the ribs are embedded in the separation gap.

[0013] Preferably, the bottom of the upper cover plate has several receiving grooves.

[0014] Preferably, the receiving groove is disposed at the edge of the spray hole.

[0015] Preferably, the number of receiving grooves at the edge of each spray hole is the same as the number of claws at the edge of the skeleton.

[0016] Preferably, the placement of the receiving groove at the edge of each spray hole corresponds one-to-one with the placement of the claws at the edge of the skeleton.

[0017] The beneficial effects of this utility model are:

[0018] This skeleton spraying fixture has a lower support plate pressed against an upper cover plate, which sprays adhesive into the spraying holes. The edges of the skeleton are sealed by the pressure of the upper cover plate, making it difficult for the adhesive to flow out of the preset bonding area, thus improving the accuracy of adhesive spraying and avoiding glue overflow during the subsequent vulcanization process.

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figures 1-2 As shown, this utility model proposes a skeleton spraying fixture, including: a lower support plate 1 and an upper cover plate 2, the skeleton is disposed between the lower support plate 1 and the upper cover plate 2, and is sealed and fixed by pressing the lower support plate 1 and the upper cover plate 2 together.

[0027] Specifically, the lower support plate 1 is provided with several workstations 11, each workstation 11 being a raised support surface. Each workstation 11 has a recessed limiting groove for placing the skeleton. The shape of the limiting groove is adapted to the shape of the skeleton; different shapes of skeletons require corresponding limiting grooves. The limiting grooves on the various workstations 11 in the lower support plate 1 can have the same or different shapes. Limiting grooves of the same shape allow the lower support plate 1 to place skeletons of the same type in batches, suitable for large-scale factory production and processing. Limiting grooves of different shapes allow the lower support plate 1 to place multiple different types of skeletons at once, providing better adaptability and compatibility.

[0028] The upper surface of the frame is higher than the top surface of station 11, which facilitates the contact between the upper cover plate 2 and the frame to achieve downward pressure. Several stations 11 in the lower support plate 1 are arranged in an array, and a separation gap 12 is provided between two adjacent stations 11.

[0029] like Figure 3 As shown, the upper cover plate 2 has several spray holes 21 to expose the bonding area of ​​the skeleton. The spray holes 21 correspond one-to-one with several workstations 11. Ribs 22 are provided between two adjacent spray holes 21. When the lower support plate 1 is assembled with the upper cover plate 2, the ribs 22 are embedded in the separation gaps 12 to facilitate better positioning and allow the upper cover plate 2 to more accurately compress the skeleton.

[0030] Furthermore, such as Figure 4As shown, the bottom of the upper cover plate 2 has several receiving grooves 23, which are located at the edges of the spray holes 21. Since the skeleton is usually equipped with claws around its perimeter, these claws need to be positioned to avoid obstruction during adhesive spraying. Therefore, in this embodiment, the receiving grooves 23 are used to isolate the claws, preventing some adhesive from adhering to them during subsequent adhesive spraying. The number of receiving grooves 23 at the edge of each spray hole 21 is the same as the number of claws at the edge of the skeleton, and the arrangement of the receiving grooves 23 at the edge of each spray hole 21 corresponds one-to-one with the arrangement of the claws at the edge of the skeleton.

[0031] In use, first, the skeleton is positioned at station 11 on the lower support plate 1 for fixation. Then, the upper cover plate 2 is placed on the lower support plate 1, with the ribs 22 embedded in the partition gaps 12. An external cylinder drives the upper cover plate 2 to press the skeleton, causing a 0.1-width inward contact between the skeleton's edge and the upper cover plate 2, resulting in the skeleton being pressed and clamped. At this point, the skeleton's edge is sealed due to the compression. Adhesive is sprayed into the spray nozzle 21, adhering to the exposed bonding area of ​​the skeleton. Because the skeleton's edge is sealed due to compression, the adhesive cannot overflow or flow to the side of the skeleton. After the adhesive is sprayed, the edges of the sprayed adhesive are immediately cured (pre-formed) using a drying or UV pre-curing device. Then, the rubber body is placed on the exposed bonding area of ​​the skeleton for bonding. The upper cover plate 2 is removed, at which point the skeleton and the rubber body are bonded together. This fixture seals the skeleton's edge due to the compression of the upper cover plate 2, preventing the adhesive from flowing out of the pre-set bonding area, improving the accuracy of adhesive spraying, avoiding overflow during subsequent vulcanization, and increasing the yield rate.

[0032] The inventors discovered that in the prior art, manual removal of excess glue requires the use of anhydrous ethanol for wiping, but anhydrous ethanol will damage the surface coating of the skeleton. In this application, there is no need to manually repair the excess glue, which reduces costs, improves processing efficiency, and also protects the surface coating of the skeleton.

[0033] In practical applications, this tooling only requires an external drive device (including but not limited to a cylinder) to drive the upper cover plate 2 to move linearly, so that the upper cover plate 2 contacts or detaches from the lower support plate 1. When the upper cover plate 2 detaches from the lower support plate 1, the skeleton in the station 11 can be replaced to achieve rapid switching, which further improves processing efficiency.

[0034] In some embodiments, an elastic sealing strip can be provided at the contact area between the upper cover plate 2 and the skeleton to prevent the adhesive from overflowing through physical sealing, or a negative pressure adsorption system can be connected to press the upper cover plate 2 and the lower support plate 1 together by vacuuming to compress the skeleton.

[0035] It is understandable that the partition gap 12 of the lower support plate 1 and the rib 22 of the upper cover plate 2 can be replaced by magnetic strips to achieve rapid positioning.

[0036] Working Principle: The skeleton is positioned and fixed at station 11 on the lower support plate 1. Then, the upper cover plate 2 is placed on the lower support plate 1, with the ribs 22 embedded in the partition gaps 12. An external cylinder drives the upper cover plate 2 to press the skeleton, causing a 0.1-width inward area of ​​the skeleton's edge to contact the upper cover plate 2, thus clamping the skeleton downward. At this point, the skeleton edge is sealed due to compression. Adhesive is sprayed into the spray nozzle 21, adhering to the exposed bonding area of ​​the skeleton. After the adhesive is sprayed, the edges of the sprayed adhesive are immediately cured using drying or UV pre-curing equipment. The rubber body is then placed on the exposed bonding area of ​​the skeleton for bonding. The upper cover plate 2 is removed, and the skeleton and rubber body are now bonded together. This fixture seals the skeleton edge due to the compression of the upper cover plate 2, preventing adhesive from flowing out of the preset bonding area, improving the accuracy of adhesive spraying, avoiding overflow during subsequent vulcanization, and increasing the yield rate. It also eliminates the need for manual trimming of overflowing adhesive, reducing costs and improving processing efficiency.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
