Description

Technical Field

[0001] This utility model relates to the field of spraying fixture technology, and more specifically, to a spraying fixture for a carbon fiber top cover of a notebook computer. Background Technology

[0002] The rapid development of laptops has led to increasingly higher demands on their quality. People are no longer satisfied with just improved performance; they also have certain requirements for their aesthetic appearance. This poses a greater challenge to the painting of laptop casings, which requires the assistance of painting fixtures.

[0003] Patent application CN2023228344029 discloses a spraying fixture for a laptop computer cover, including a movable base. A support rod is located at the upper end of the movable base, and a conical material collection groove is rotatably connected to the upper end of the support rod. A rectangular annular protrusion is located at the upper end of the conical material collection groove. A positioning mechanism for the laptop computer cover is located on the inner wall of the rectangular annular protrusion near the conical material collection groove. This invention uses the rectangular annular protrusion in conjunction with the conical material collection groove to collect residual spraying material, facilitating recycling and saving spraying costs. By inserting the laptop computer cover into the rectangular annular protrusion, a spring on a horizontal limiting rod, in conjunction with a limiting block, clamps and positions the laptop computer cover, preventing displacement during spraying and improving the spraying effect. A small motor drives a fan blade to rotate, which, in conjunction with an inclined baffle, blows air to dry the sprayed surface of the laptop computer cover within the rectangular annular protrusion, allowing the sprayed surface to cool and solidify quickly, improving spraying efficiency.

[0004] This structure has certain problems during use: when limiting the carbon fiber cap, multiple spring resistances must be overcome simultaneously, making single-person operation extremely inconvenient; when adapting to caps of different specifications, situations of excessive or insufficient pressure may occur. In addition, this structure uses a fan for direct drying to improve curing efficiency, but excessively strong airflow can easily lead to uneven coating distribution and a small drying range, ultimately resulting in a double decrease in processing efficiency and quality. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spraying fixture for carbon fiber top covers of notebook computers, so as to improve the compatibility and spraying efficiency of the fixture and solve the above-mentioned background technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0024] Please see Figure 1-5 In this utility model, a spraying fixture for a carbon fiber top cover of a notebook computer includes a rectangular frame 1 and a collection hopper 2 installed at its bottom. The bottom of the collection hopper 2 is detachably connected to a collection box 3 by bolts. A filter screen 13 is slidably connected to the inner wall of the collection hopper 2. The filter screen 13 is located at the top of the collection box 3. An expansion box 4 is evenly distributed on the outer side of the rectangular frame 1. An internally threaded post 5 is slidably connected to the inner wall of the expansion box 4. An adjusting shaft 6 is threaded inside the internally threaded post 5. The other end of the adjusting shaft 6 passes through and extends to the outside of the expansion box 4. The end of the internally threaded post 5 away from the adjusting shaft 6 passes through and extends into the interior of the rectangular frame 1. A limiting plate 7 is fixedly installed on the internally threaded post 5. Two guide shafts 12 are fixedly connected to the limiting plate 7. The other end of the guide shafts 12 passes through and extends into the interior of the expansion box 4. An auxiliary component 8 is evenly distributed on the rectangular frame 1.

[0025] The auxiliary component 8 includes a drying box 801, which is fixedly installed on the outside of the rectangular frame 1. A fan 802 is fixedly installed on the outside of the drying box 801. An electric heating wire 803 is fixedly installed on the inner wall of the drying box 801. Air nozzles 804 arranged at equal intervals are fixedly installed on the inner wall of the drying box 801. The air nozzles 804 penetrate and extend to the inside of the rectangular frame 1. A guide plate 9 is fixedly installed on the inner wall of the drying box 801. A through groove 10 is formed between the guide plate 9 and the inner wall of the drying box 801. The electric heating wire 803 and the air nozzles 804 are located on both sides of the guide plate 9.

[0026] The operator first rotates the adjustment shaft 6 on the outside of the expansion box 4, and drives the internal threaded column 5 to slide along the guide shaft 12 through the threaded transmission, pushing the limiting plate 7 to move towards the center of the rectangular frame 1. By simultaneously adjusting the position of multiple sets of limiting plates 7, they are precisely inserted into the edge groove of the carbon fiber cover. This design can adapt to the dimensional tolerances of different batches of covers, ensuring that the workpiece does not shift during the subsequent spraying process.

[0027] After positioning, the spraying equipment sprays the paint from above the rectangular frame 1, atomizing the paint. Most of the paint adheres directly to the surface of the top cover, while the remaining oversprayed paint falls under gravity. The collection hopper 2 guides the paint to the central area through its inclined inner wall. After preliminary filtration by the stainless steel filter screen 13, the liquid paint enters the detachable collection box 3, while solid impurities are intercepted above the filter screen 13, achieving waste classification and recycling.

[0028] After the spraying is completed, the auxiliary component 8 is started immediately. The fan 802 draws in air, which is heated by the heating wire 803. The high-temperature airflow passes through the channel 10 under the constraint of the guide plate 9, forming a laminar flow state. The air nozzle 804 sprays the hot air evenly onto the surface of the top cover, so that the coating can quickly reach the surface dry state.

[0029] After the coating has cured, the operator can directly remove the workpiece vertically upwards. Collection box 3 can be disassembled and cleaned separately.

[0030] In this invention, the precision threaded engagement between the adjusting shaft 6 and the internal threaded column 5, along with the limiting guidance of the guide shaft 12, enables the position adjustment of the limiting plate 7 to accommodate workpieces of different specifications. The combination of the inclined design of the collecting hopper 2 and the filter screen 13 improves the paint recovery rate. Meanwhile, the electric heating wire 803 in the auxiliary component 8, together with the air nozzle 804, forms a uniform hot air flow, which shortens the curing time compared to the traditional drying method, thereby improving the compatibility of the fixture and the spraying efficiency.

[0031] Please see Figure 1-3 The rectangular frame 1 has uniformly distributed protective plates 11 fixedly installed on its inner wall. The protective plates 11 are located on the top of the drying box 801 and are in an inclined state.

[0032] In this invention, the protective plate 11 can prevent the paint from being directly sprayed onto the air nozzle 804 during the spraying process, thus preventing the air nozzle 804 from becoming clogged.

[0033] Please see Figure 5 Among them, the outer side of the expansion box 4 is connected to a dustproof net 14, which shields the fan 802.

[0034] In this invention, during the air intake process of the fan 802, the dustproof net 14 can filter the incoming airflow and prevent dust from accumulating inside the drying box 801.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
