Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] Please see Figure 1-6 A coating shielding fixture includes a support frame 1 and a cover plate assembly 2 hinged to the support frame 1. The support frame 1 is provided with a lifting unit 3 and a placement unit 11 for placing products. The lifting unit 3 is connected to the support frame 1, and the placement unit 11 is connected to the lifting unit 3. The lifting unit 3 is used to drive the placement unit 11 upward so that the top of the product on the placement unit 11 fits against the cover plate assembly 2. A gap is provided between the cover plate assembly 2 and the placement unit 11 for external paint to be sprayed onto the outer ring of the product.
[0030] In practical applications, the operator rotates and opens the cover assembly 2, opening the upper part of the placement unit 11. The product to be painted is placed on the placement unit 11, and the cover assembly 2 is rotated down. It should be noted that the cover assembly 2 covers the upper part of the product, with the product located below the cover assembly 2 and a gap between the product and the cover assembly 2. The operator drives the lifting unit 3 to press the top of the product on the placement unit 11 tightly against the cover assembly 2, thus forming a tight-fitting structure of placement unit 11-product-cover assembly 2, and the outer edge of the product is not blocked by the placement unit 11. Then, the entire coating shielding fixture is placed in the coating and painting area for coating and painting. The paint is only applied to the outer edge of the product and not to the inside. The coated product is then removed and baked at high temperature. Products coated by the coating shielding fixture can effectively prevent the product from deforming due to heat during high-temperature baking, thus improving the quality of the product.
[0031] Preferably, the lifting unit 3 includes a transmission component 31, a movable block 32, and a fixed block 33. The two ends of the transmission component 31 are rotatably connected to the support frame 1. The fixed block 33 is connected to both sides of the support frame 1. The fixed block 33 is provided with a vertically arranged slide rail 331. The movable block 32 is slidably connected to the slide rail 331. The transmission component 31 is hinged to the movable block 32. The transmission component 31 is provided with a pull rod 311 for driving the transmission component 31 to swing. The movable block 32 is connected to the placement unit 11.
[0032] In the above design, the operator can drive the transmission component 31 to swing by pulling the lever 311, so that the movable block 32 slides up and down along the slide rail 331 within the fixed block 33, thereby driving the placement unit 11 to slide up and down. Specifically, when the operator pulls the lever 311 downward, the movable block 32 moves upward along the slide rail 331, thereby driving the placement unit 11 upward, so that the top of the product on the placement unit 11 is in close contact with the cover plate assembly 2, which helps to prevent paint from being applied inside the product and prevents the product from deforming due to heat during high-temperature baking; when the operator pulls the lever 311 upward, the movable block 32 moves downward along the slide rail 331, thereby driving the placement unit 11 downward, so that the product on the placement unit 11 is away from the cover plate assembly 2, making it easier for the operator to remove the product.
[0033] Preferably, the transmission component 31 includes a connecting plate 312 and a connecting rod 313. The connecting plate 312 is connected to the connecting rod 313. Both ends of the connecting rod 313 are rotatably connected to the support frame 1. The pull rod 311 is connected to one side of the connecting rod 313. The connecting plate 312 is hinged to the movable block 32.
[0034] With the above design, when the operator pulls the lever 311 up or down, the connecting rod 313 rotates in the direction of pulling, so that the connecting plate 312 and the movable block 32 rotate, so that the movable block 32 moves up or down along the slide rail 331, and drives the placement unit 11 to move up or down, which is beneficial to the operator.
[0035] Preferably, the movable block 32 is provided with a limiting post 321 for fixing the connecting plate 312. The limiting post 321 is located on the side of the movable block 32 near the pull rod 311. When the connecting plate 312 abuts against the limiting post 321, the top of the product on the placement unit 11 is in contact with the cover plate assembly 2.
[0036] In this embodiment, when the worker pulls the lever 311 down to the bottom, the movable block 32 slides to the top of the slide rail 331. At this time, both the connecting plate 312 and the movable block 32 are in a vertical state. At this time, the limiting post 321 can prevent the connecting plate 312 and the movable block 32 from tilting further. This is beneficial to fixing the height of the placement unit 11 so as to ensure that the top of the product on the placement unit 11 is always in close contact with the cover plate assembly 2 during the painting process. When the worker pulls the lever 311 up to the top, the movable block 32 slides down along the slide rail 331, and the connecting plate 312 and the movable block 32 are tilted away from the lever 311.
[0037] Preferably, the cover plate assembly 2 includes a connecting frame 21 and a cover plate 22. The cover plate 22 is connected to the connecting frame 21, and the connecting frame 21 is hinged to the support frame 1. The connecting frame 21 can drive the cover plate 22 to rotate along the support frame 1.
[0038] In the above design, the connecting frame 21 can drive the cover plate 22 to rotate along the support frame 1, so as to facilitate the staff to open or close the cover plate 22. Specifically, opening the cover plate 22 can open the space above the placement unit 11; closing the cover plate 22 can cover the space above the placement unit 11. In other words, opening the cover plate 22 can facilitate the staff to place or take out the product, and closing the cover plate 22 can cover the product, thereby preventing paint from being applied inside the product.
[0039] Preferably, the connecting frame 21 is provided with a handle 212.
[0040] In this embodiment, the handle 212 facilitates the operation of the connecting frame 21 by the staff. Specifically, the connecting frame 21 is also provided with a limiting plate, which can limit the opening angle of the connecting frame 21, so that the staff does not need to hold the connecting frame 21 after opening the cover 22, and the connecting frame 21 will not open to too large an angle, which would make it inconvenient for the staff to operate.
[0041] Preferably, the support frame 1 is provided with a fixing member 12, the fixing member 12 is provided with a groove 121, the handle 212 is provided with a rotatably connected barb 2121, the barb 2121 cooperates with the groove 121, and the cover plate 22 is fixed in the closed state.
[0042] In this embodiment, when the groove 121 and the barb 2121 are engaged, the cover plate 22 can be further fixed on the placement unit 11. This is beneficial because when painting, the top of the product can be in close contact with the cover plate 22, thereby preventing paint from being sprayed into the interior of the product.
[0043] Example 2
[0044] Please see Figure 7-8 A coating system includes the aforementioned coating shielding fixture, rotating module 4, and spraying module 5. The rotating module 4 is provided with a spraying area 7 and a painting area 6. The coating shielding fixture is connected to the rotating module 4. The rotating module 4 can be used to drive the coating shielding fixture to rotate so that the coating shielding fixture enters or leaves the working area of the spraying module 5.
[0045] In actual operation, the staff places the product to be painted in the painting shielding fixture, and uses the lifting unit 3 to press the top of the product tightly against the cover plate assembly 2. The product is then rotated to the painting area 7 by the rotating module 4 to paint the outer edge of the product. After the painting is completed, the product is rotated to the painting area 6 by the rotating module 4. The staff takes out the painted product and bakes it at high temperature to complete the entire painting process. The painting shielding fixture can prevent the product from deforming due to heat during the high temperature baking after painting.
[0046] Preferably, the rotating module 4 includes a rotating block 41 and at least two fixing frames 42 for fixing the coating shielding fixture. The fixing frames 42 are connected to the rotating block 41, and the coating shielding fixture is detachably connected to the fixing frames 42.
[0047] In this embodiment, there are two fixing frames 42. The number of coating shielding fixtures and fixing frames 42 are matched, so that two products can be painted at the same time. While the products are being painted, another product to be painted can be placed, thereby improving work efficiency.
