Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying jigs, in particular to a plastic part spraying jig and a spraying device. Background Art
[0002] In the fields of consumer electronics, automotive interiors, and household appliances, the appearance and functional identification of plastic parts is one of the key quality indicators. In the production process of plastic parts, in order to add functional identification (such as characters on buttons) to the painted plastic parts, these plastic parts will be engraved with characters after painting by laser laser engraving technology to remove the paint layer to achieve the functional identification of buttons or panels. Laser laser engraving can accurately remove the paint layer on the surface of the plastic through a high-energy laser beam to expose the underlying material. Since laser laser engraving has high precision and stability, it can accurately remove the surface paint on the front of the light-transmitting area of the plastic parts. Therefore, under normal circumstances, there will be no paint residue in the character area on the front of the light-transmitting area of the plastic parts, ensuring the clarity and light transmittance of the characters.
[0003] However, during the painting process, although the back of the light-transmitting area of the plastic part can be covered with a plastic part painting jig, it is difficult for the jig to fit completely with the plastic part and there is a gap, which causes the paint mist generated during the painting to splash onto the back of the plastic part through these gaps. If the paint mist adheres to the light-transmitting area of the characters, it will seriously affect the light-transmitting effect, thereby reducing the function and user experience of the plastic part. Although tape can be used to cover the back of the light-transmitting area of the plastic part, and the tape can be torn off after each painting to prevent the paint mist from contaminating the back of the light-transmitting area of the plastic part, repeatedly sticking tape not only wastes time, but also causes cost waste.
[0004] Therefore, there is an urgent need for a plastic part painting jig that can protect the back of the light-transmitting area of the plastic part from being contaminated by paint mist and can be reused. Utility Model Content
[0005] The utility model aims to provide a plastic part painting jig which can protect the back of the light-transmitting area of the plastic part from being polluted by paint mist and can be repeatedly used.

[0028] Please refer to Figure 1-Figure 2As shown, the present application provides a plastic part spraying jig, which can protect the back of the light-transmitting area of the plastic part from being polluted by paint mist, and can be repeatedly used. The device includes a frame 1, a fixing member 2 and an elastic seal 3, wherein the fixing member 2 is arranged on the frame 1, the plastic part can be fixed on the fixing member 2, and the elastic seal 3 is detachably arranged on the fixing member 2. When the fixing member 2 fixes the plastic part, the elastic seal 3 is used to have an interference fit with the back of the light-transmitting area of the plastic part, so that the elastic seal 3 fits tightly to the plastic part to form an efficient seal, shielding the back of the light-transmitting area of the plastic part, and preventing paint mist or impurities from penetrating to the back of the light-transmitting area during the painting process, which can ensure that the back of the light-transmitting area of the plastic part is free of pollution and maintain its function and appearance quality. At the same time, the elastic seal 3 can also ensure the stability of the painting process, and will not cause uneven painting due to vibration or displacement, thereby improving the appearance quality of the plastic part. Since the elastic seal 3 is a detachable design, it can be used repeatedly, which reduces the replacement frequency of the overall equipment and reduces the cost of use.
[0029] like Figure 1 As shown, in some embodiments, a through hole 7 is provided on the fixing member 2, and it is set to a hollow structure. The through hole 7 can allow the paint mist to penetrate the fixing member 2 and be discharged from the plastic part spray painting fixture, rather than directly rebounding back to the surface of the plastic part, thereby reducing the probability of the paint mist rebounding to the back of the light-transmitting area of the plastic part, and reducing the risk of the back of the light-transmitting area of the plastic part being contaminated. Furthermore, some plastic parts are provided with through holes, and the through hole 7 on the fixing member 2 can be set to a shape that matches the through hole on the plastic part. Such a design can achieve precise matching, effectively reduce the gap between the plastic part spray painting fixture and the plastic part, and further reduce the possibility of the paint mist splashing through the gap to the back of the light-transmitting area of the plastic part, thereby protecting the light-transmitting area from contamination.
[0030] like Figure 2 As shown, in some embodiments, multiple elastic seals 3 can be provided, and multiple elastic seals 3 are distributed circumferentially around the through hole 7 and correspond one by one to the back of the light-transmitting area of the plastic part; wherein, multiple elastic seals 3 can accurately correspond to the back of each light-transmitting area on the plastic part, provide targeted sealing protection, and reduce the use of unnecessary sealing materials while ensuring that each light-transmitting area is individually protected, saving costs; and the distribution of multiple elastic seals 3 can be flexibly adjusted, and can adapt to light-transmitting areas of plastic parts of different shapes and sizes, thereby increasing the flexibility and adaptability of the plastic part painting jig. In other embodiments, the elastic seal 3 is annular, and the elastic seal 3 is arranged around the periphery of the through hole 7; wherein, the annular elastic seal 3 can completely surround the periphery of the through hole 7, directly and comprehensively seal the back of the plastic part, and can effectively prevent paint mist from entering through the gap, thereby protecting the back of the light-transmitting area of the plastic part and other key parts from being contaminated by paint mist.
[0031] It should be noted that the elastic seal 3 can be, but is not limited to, a sponge patch or a silicone pad. In order to prevent the elastic seal 3 from moving during the assembly process with the plastic part, in some embodiments, a groove is provided on the fixing part 2, and the elastic seal 3 is embedded in the groove, and the thickness of the elastic seal 3 is higher than the depth of the groove; wherein, the groove provides a fixed position for the elastic seal 3, so that the elastic seal 3 remains stable during operation. The design that the thickness of the elastic seal 3 is higher than the depth of the groove ensures that the elastic seal 3 can be pressed against the back of the light-transmitting area of the plastic part during assembly, ensuring the sealing effect, and further ensuring the light transmittance and clarity of the back area of the light-transmitting area of the plastic part. Optionally, the thickness of the elastic seal 3 is 0.5mm-1mm higher than the depth of the groove.
[0032] In other embodiments, the elastic seal 3 can be, but is not limited to, a detachable method such as Velcro, which is not specifically limited here. In some embodiments, a card slot 4 is provided on the fixing member 2 to clamp and fix the plastic part. The card slot 4 is designed to tightly clamp the plastic part to ensure that it remains stable during processes such as painting and laser engraving, prevent displacement or movement of the plastic part, and improve the precision and accuracy of the process; at the same time, the card slot 4 makes the installation and removal of the plastic part easier and faster, without the need for additional tools or complex fixing devices, reducing assembly time, improving production efficiency, and effectively avoiding the probability of damage to the plastic part due to the installation and removal of the plastic part during the assembly process. In other embodiments, the connection method between the plastic part and the fixing member 2 can also be a pin connection or an adhesive connection, which is not specifically limited here.
[0033] Optionally, a plurality of support legs 6 are arranged around the side of the frame 1 facing away from the plastic part, wherein the support legs 6 can increase the stability of the plastic part spray painting jig; wherein, the plurality of support legs 6 are arranged at the four corners of the frame 1, so that the plastic part spray painting jig is more stable. Furthermore, the plastic part spray painting jig also includes a plurality of criss-cross connecting rods 5, the connecting rods 5 connect and fix the frame 1 and the fixing part 2, and since the middle of the plurality of criss-cross connecting rods 5 is hollowed out, the paint mist generated during the spray painting process can be discharged through the gaps of the connecting rods 5, effectively reducing the probability of the paint mist rebounding to the back of the light-transmitting area of the plastic part, thereby protecting the back of the light-transmitting area of the plastic part from contamination.
[0034] To save costs, the frame 1 and the fixing member 2 of the plastic parts spray painting fixture may be made of, but not limited to, plastic and other materials.
[0035] The present application also provides a paint spraying device, including a paint sprayer and a plastic part paint spraying jig of any of the above-mentioned embodiments, wherein the paint sprayer sprays paint onto a plastic part fixed on the plastic part paint spraying jig. The plastic part paint spraying jig uses an elastic seal 3 to be interference-fitted with the back of the light-transmitting area of the plastic part when the plastic part is fixed on the fixing part 2, so that the elastic seal 3 fits tightly to the plastic part to form an efficient seal, shielding the back of the light-transmitting area of the plastic part, and preventing paint mist or impurities from penetrating to the back of the light-transmitting area during the painting process. It can ensure that the back of the light-transmitting area of the plastic part is free of pollution and maintain its function and appearance quality. At the same time, the elastic seal 3 can also ensure the stability of the painting process, and will not cause uneven painting due to vibration or displacement, thereby improving the appearance quality of the plastic part. Since the elastic seal 3 is a detachable design, it can be used repeatedly, which reduces the replacement frequency of the overall equipment and reduces the cost of use.
[0036] It should be noted that the paint spraying machine can be, but is not limited to, a paint spraying robot, a fixed paint spraying machine, or a reciprocating paint spraying machine, etc., and no specific limitation is made here.
