Description

Technical Field

[0001] This utility model relates to the field of automotive parts spraying technology, specifically to an anti-fogging spraying tool for automotive lamp covers. Background Technology

[0002] In the production process of automotive headlight covers, the spraying process is a crucial step that determines the product's quality and appearance. Through spraying, not only can the headlight cover be given a specific color and gloss, but its resistance to ultraviolet rays and corrosion can also be enhanced, improving the product's durability and aesthetics.

[0003] However, in the actual spraying process, the problem of paint mist splattering has always been a challenge for the industry. Once paint mist splatters onto parts of the lampshade that do not need to be sprayed, it will not only damage the uniformity of the lampshade's appearance, causing surface defects and unevenness, but may also affect the subsequent assembly accuracy, increasing rework costs and production cycle.

[0004] Currently, most automotive headlight cover anti-paint fog spraying fixtures on the market use protective barriers to isolate paint fog. However, in actual applications, due to the inherent characteristics of the hinge structure, gaps inevitably exist at the hinges of the protective barriers. During spraying, paint fog can escape through these gaps, causing the protective barriers to fail to achieve the expected protective effect, which in turn affects the spraying quality of the automotive headlight covers and makes it difficult to improve the product qualification rate.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-3 As shown, this utility model is a tooling for spraying anti-paint fog on automotive lamp covers, comprising:

[0031] Spray painting frame 11;

[0032] The protective components include a first protective frame 21, a second protective frame 22, an inner groove 23, a rotating rod 24, a rotating ring 25, and a baffle 26. The first protective frame 21 and the second protective frame 22 are located at the two ends of the top of the spraying frame 11, the inner groove 23 is opened at the upper part of both ends of the outer surface of the spraying frame 11, the rotating rod 24 is set on the inner surface of the inner groove 23, the rotating ring 25 is sleeved on the outer surface of the rotating rod 24, one end of the baffle 26 is rotatably connected to the outer surface of the rotating ring 25, and the other end is blocked on one side of the outer surface of the first protective frame 21 and the second protective frame 22 respectively.

[0033] The sealing gasket 34 is embedded in the sealing groove 35, so that the first protective frame 21 and the second protective frame 22 can form a tight sealing structure when surrounding the car headlight cover. The rotating ring 25 rotates outside the rotating rod 24, which drives the baffle 26 to block the lower outer part of the first protective frame 21 and the second protective frame 22 respectively, further enhancing the fit between the protective frames. This effectively prevents paint mist from escaping from the gaps in the protective frames, and can create a nearly closed space for the painting operation of the car headlight cover. This greatly reduces the contamination of the non-painted areas of the headlight cover by paint mist, significantly improves the painting quality of the headlight cover, reduces the rework rate caused by paint mist contamination, and ensures the consistency of the product's appearance and assembly accuracy.

[0034] A limiting ring 27 is provided on the outer surface of the rotating rod 24, and the limiting ring 27 is attached to both sides of the outer surface of the rotating ring 25;

[0035] When the rotating ring 25 rotates outside the rotating rod 24, the limiting ring 27 will fit against both sides of the rotating ring 25, which can limit the rotation of the ring 25.

[0036] Both the first protective frame 21 and the second protective frame 22 are transparent, and a support strip 28 is fixedly connected between the two baffles 26.

[0037] It also includes a fixing component, which includes an inner groove 31, a threaded rod 32 and a nut ring 33. The inner groove 31 is opened at the bottom of the baffle 26. The threaded rod 32 is respectively set at the lower part of one side of the protective frame 21 and the second protective frame 22 and is embedded in the inner groove 31. The nut ring 33 is threaded to the outer surface of the threaded rod 32.

[0038] When the baffle 26 blocks the lower part of the outer side of the first protective frame 21 and the second protective frame 22 respectively, the threaded rod 32 is embedded in the inner groove 31. By rotating the nut ring 33, the nut ring 33 is made to fit against the outer side of the baffle 26, thus fixing the position of the baffle 26 after rotation.

[0039] A sealing groove 35 is provided on the other side of the outer surface of the protective frame 21, and a sealing gasket 34 is adhered to the other side of the outer surface of the protective frame. The sealing gasket 34 is embedded inside the sealing groove 35.

[0040] When the first protective frame 21 and the second protective frame 22 are attached together, the sealing gasket 34 is simultaneously embedded inside the sealing groove 35.

[0041] A support frame 12 is welded to one end of the outer surface of the spraying frame 11. A drive rod 13 is provided at the bottom of the support frame 12. A spraying cavity 14 is provided at the bottom of the drive rod 13. A spraying head 15 is fixedly connected to the bottom of the spraying cavity 14.

[0042] The position of the spray head 15 is extended by the drive rod 13, and the spray liquid is transmitted to the spray head 15 for spraying through the spraying chamber 14.

[0043] Working principle: In the automotive lamp cover painting operation, the position of the spray head 15 is extended by the drive rod 13. The spraying chamber 14 stably transmits the spray liquid to the spray head 15 for spraying. At the start of the operation, the automotive lamp cover is placed on top of the spraying machine frame 11, and the protective frame 1 21 and the protective frame 22 are pushed, so that the sealing gasket 34 is tightly embedded in the sealing groove 35, thereby surrounding the automotive lamp cover with the protective frame 1 21 and the protective frame 22 to form initial protection. Subsequently, the rotating ring 25 rotates outside the rotating rod 24. At this time, the limiting ring 27 will be tightly attached to both sides of the rotating ring 25. Through this limiting structure, To ensure the stability and accuracy of the rotation of the rotating ring 25, the baffles 26 at both ends are placed on the lower part of the outer side of the first protective frame 21 and the second protective frame 22, respectively. At this time, the threaded rod 32 is embedded in the inner groove 31. By rotating the nut ring 33, it is made to fit against the outer side of the baffle 26, thus fixing the position of the baffle 26 after rotation. This series of operations makes the first protective frame 21 and the second protective frame 22 fit tightly, effectively blocking the channel for paint mist to escape through the gap. While providing a stable protective environment for the painting of automotive headlight covers, it also avoids paint mist pollution of the work space and improves the environmental protection and standardization of the painting operation.

[0044] Please see Figure 1 , Figure 3 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0045] The dustproof component includes a hydraulic rod 41, a telescopic rod 42, a side plate 48, and a rubber sleeve 44. The hydraulic rod 41 is located at one end of the outer surface of the support frame 12, the telescopic rod 42 is located at the outer end of the hydraulic rod 41, the side plate 48 is fixed to the outer end of the telescopic rod 42, and the rubber sleeve 44 is located at the outer end of the side plate 48 and is sleeved on the outer surface of the spray head 15.

[0046] The hydraulic rod 41 drives the telescopic rod 42 to extend, so that the rubber sleeve 44 is fitted on the outside of the spray head 15, which can prevent dust from the external environment from adhering and entering the inside of the spray head 15.

[0047] A groove 45 is provided at one end of the side plate 48. A slider 43 is provided on the outer surface of the rubber sleeve 44. The slider 43 is movably connected to the inside of the groove 45. Insertion holes 46 are provided at the top and bottom of the inner surface of the groove 45. Insert rods 47 are fixed at the top and bottom of the slider 43. The insert rods 47 are inserted into the inside of the insertion holes 46.

[0048] By sliding the slider 43 inside the groove 45, the position of the rubber sleeve 44 can be moved. After the insertion rod 47 is inserted into the insertion hole 46, the position of the rubber sleeve 44 after moving upward or downward can be fixed.

[0049] Working principle: When protection of the spray head 15 is required, the hydraulic rod 41 exerts its power to drive the telescopic rod 42 to extend through hydraulic transmission, which in turn moves the rubber sleeve 44 fitted at the end of the telescopic rod 42 toward the spray head 15 until the rubber sleeve 44 is completely fitted over the outside of the spray head 15, forming an isolation barrier that effectively prevents dust from the external environment from entering the inside of the spray head 15, ensuring the cleanliness of the inside of the spray head 15 and preventing dust from affecting the spraying quality.

[0050] In actual operation, if it is necessary to adjust the position of the rubber sleeve 44, the sliding structure of the slider 43 and the groove 45 can be used. The slider 43 can slide flexibly in the groove 45. By pushing the slider 43 with external force, the rubber sleeve 44 can be moved on the track defined by the groove 45, so as to achieve precise adjustment of the position of the rubber sleeve 44. When the rubber sleeve 44 moves to the appropriate position, the insert rod 47 is inserted into the corresponding insertion hole 46. The cooperation between the insert rod 47 and the insertion hole 46 forms a mechanical limit, which restricts the sliding of the slider 43 in the groove 45, thereby firmly fixing the position of the moved rubber sleeve 44, ensuring that the rubber sleeve 44 remains stable in subsequent spraying operations and continuously provides reliable protection for the spray head 15.

[0051] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
