Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for spraying and masking decorative rings for cameras. Background Technology

[0002] In the manufacturing process of consumer electronic devices (such as smartphones and tablets), camera decorative rings are important appearance components, and their surfaces typically require coating to achieve specific decorative effects and protective properties. However, the structure of camera decorative rings is often quite complex. In addition to the areas that need to be coated, there are also areas where coating should be avoided, such as the assembly connection points with the device housing and around positioning holes.

[0003] To ensure coating quality and prevent paint contamination of areas to be avoided during spraying, existing technologies typically employ masking fixtures to shield these areas. For example... Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The traditional masking fixture consists of five layers of cover plates and multiple fasteners. This design means greater raw material consumption, resulting in higher overall costs. Furthermore, during installation, operators must first stack and align the five cover plates in sequence, ensuring the positioning holes of each layer perfectly align, and then install the multiple fasteners one by one. This process requires repeated adjustments to prevent the cover plates from shifting. For mass production, this installation method severely impacts assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a camera decorative ring spraying masking fixture, which aims to solve the problems of high cost and cumbersome disassembly and assembly of masking fixtures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a camera decorative ring spraying masking fixture, including:

[0007] A cover plate is provided in the spraying avoidance area of ​​the spraying surface of the camera decorative ring, and the cover plate is provided with at least two connecting holes opposite each other;

[0008] An elastic element includes at least two elastic portions disposed opposite to each other;

[0009] After the cover plate is installed in place, both elastic parts pass through the camera decorative ring and are respectively inserted into the two connecting holes. The two elastic parts apply elastic forces in opposite directions to the cover plate to fix the cover plate to the camera decorative ring.

[0010] Furthermore, each of the elastic parts is provided with a latch that engages with the connecting hole, and the latch abuts against one side of the connecting hole under the action of elastic force.

[0011] Furthermore, the elastic part includes a first limiting segment and a second limiting segment, the first limiting segment and the second limiting segment are arranged at an angle, and the angle between the first limiting segment and the second limiting segment constitutes the bayonet.

[0012] Furthermore, the connecting hole includes an abutting side that abuts against the bayonet, and the abutting side is aligned with the corner portion of the camera decorative ring extending towards the center, so that the bayonet abuts against both the abutting side and the corner portion simultaneously under the action of elastic force.

[0013] Furthermore, the surface of the contact side is arc-shaped.

[0014] Furthermore, the connecting hole also includes a straight side opposite to the abutting side, and two inclined sides connecting the abutting side and the straight side.

[0015] Furthermore, the distance between the two inclined sides gradually increases from the end closer to the abutting side to the end closer to the straight side.

[0016] Furthermore, the elastic element includes an intermediate connecting section, with the elastic part connected to each end of the intermediate connecting section, and the connection between the elastic part and the intermediate connecting section is set at an angle.

[0017] Furthermore, the elastic portion also includes an extension section, one end of which is connected to the first limiting section, and the other end of which is connected to the intermediate connecting section.

[0018] Furthermore, the elastic element is a one-piece molded structure.

[0019] The advantages of this utility model compared to the prior art are as follows: A camera decorative ring spraying masking fixture includes a masking cover and an elastic element. The masking cover is disposed in the spraying avoidance area of ​​the camera decorative ring spraying surface, and the masking cover has at least two oppositely arranged connecting holes. The elastic element includes at least two oppositely arranged elastic portions. After the masking cover is installed in place, both elastic portions pass through the camera decorative ring and are respectively inserted into the two connecting holes. The two elastic portions apply opposite elastic forces to the masking cover to fix the masking cover to the camera decorative ring. This fixture can achieve precise masking of the spraying avoidance area only through the cooperation of the masking cover and the elastic element, eliminating the need for traditional multi-layered masking cover structures and multiple fasteners, significantly reducing the number of parts and thus greatly reducing costs. At the same time, the opposite elastic forces of the elastic portions can achieve automatic fixation of the masking cover and the camera decorative ring, making assembly and disassembly convenient and quick.

[0037] like Figures 3 to 7 As shown, this utility model embodiment provides a camera decorative ring spraying masking fixture, including a masking cover plate 1 and an elastic member 2. The masking cover plate 1 is disposed in the spraying avoidance area of ​​the spraying surface of the camera decorative ring 100. The masking cover plate 1 has at least two connecting holes 11 arranged opposite to each other. The elastic member 2 includes at least two elastic parts 21 arranged opposite to each other. After the masking cover plate 1 is installed in place, both elastic parts 21 pass through the camera decorative ring 100 and are respectively inserted into the two connecting holes 11. The two elastic parts 21 apply elastic forces in opposite directions to the masking cover plate 1 to fix the masking cover plate 1 to the camera decorative ring 100.

[0038] The cover plate 1 is made of a material with certain structural strength, such as ABS plastic or aluminum alloy. Its shape is adapted to the sprayed avoidance area of ​​the camera decorative ring 100 to ensure the sealing performance of the cover. At least two connecting holes 11 are provided opposite each other at the edge position of the cover plate 1. In this embodiment, two connecting holes 11 are preferably provided, and the two connecting holes 11 are symmetrically distributed along the central axis of the cover plate 1.

[0039] The elastic element 2 is made of a material with good elastic recovery properties, such as spring steel. It includes an intermediate connecting section 23 and two elastic parts 21 connected to both ends of the intermediate connecting section 23. The two elastic parts 21 are arranged opposite each other and at an angle to the connection with the intermediate connecting section 23, so that the elastic element 2 has a U-shaped frame structure. Each elastic part 21 includes an extension section 22, a first limiting section 211 and a second limiting section 212 connected in sequence. One end of the extension section 22 is fixedly connected to the intermediate connecting section 23, and the other end is obliquely connected to the first limiting section 211. The first limiting section 211 and the second limiting section 212 are arranged at a 120° angle, and a latch 213 is formed at the angle between them. The latch 213 is used to engage with the connecting hole 11 on the cover plate 1.

[0040] During the assembly process, the operator can first attach the cover plate 1 to the sprayed surface of the camera decorative ring 100, so that the cover plate 1 completely covers the sprayed avoidance area. At this time, the abutting side 111 of the connecting hole 11 on the cover plate 1 is aligned with the corner portion 110 of the camera decorative ring 100 extending towards the center. Then, the two elastic parts 21 of the elastic member 2 are passed through the hollow portion 120 of the camera decorative ring 100, and the snaps 213 of the elastic parts 21 are inserted into the connecting holes 11 of the cover plate 1. During insertion, the two elastic parts 21 undergo opposing elastic deformation due to compression. When the latch 213 is fully inserted into the connecting hole 11, the elastic parts 21 open outward under their own elastic restoring force. At this time, the latch 213 formed by the first limiting segment 211 and the second limiting segment 212 will abut against the abutting side 111 of the connecting hole 11. At the same time, since the abutting side 111 is aligned with the corner part 110 of the camera decorative ring 100, the latch 213 will also form a double abutting with the corner part 110, thereby causing the two elastic parts 21 to apply elastic forces (i.e., tension outward along the radial direction of the cover plate 1) in opposite directions to the cover plate 1, firmly fixing the cover plate 1 to the camera decorative ring 100.

[0041] When disassembly is required, the operator only needs to press the ends of the two elastic parts 21 in the middle to make the elastic parts 21 overcome the elastic force and deform in opposite directions. The abutment relationship between the bayonet 213 and the connecting hole 11 is released, and the elastic part 2 can be pulled out from the cover plate 1 and the camera decorative ring 100. Then the cover plate 1 can be removed. The entire disassembly and assembly process does not require any tools.

[0042] By cleverly combining the cover plate 1 and the elastic element 2, automatic fixing is achieved by utilizing the reverse elastic force of the elastic part 21. Compared with the traditional structure that uses multiple layers of cover plates and is fixed by fasteners such as screws and clips, the use of parts is reduced, and material and processing costs are significantly reduced. At the same time, the elastic snap-fit ​​fixing method greatly improves the efficiency of disassembly and assembly.

[0043] It should be noted that, depending on the process requirements, the number of surfaces that need to be coated on the camera decorative ring 100 varies. Specifically, some camera decorative rings 100 only need to be coated on one surface (i.e., the coating surface is located on the upper or lower surface of the camera decorative ring 100), while others need to be coated on two surfaces (i.e., the coating surfaces are located on the upper and lower surfaces of the camera decorative ring 100). When only one surface needs to be coated, only one masking cover plate 1 is needed to cover the coating avoidance area of ​​the coating surface. When two surfaces need to be coated, only two masking cover plates 1 are needed to cover the coating avoidance area of ​​the coating surface. Compared with traditional fixtures, this significantly reduces the number of parts used.

[0044] In one embodiment, the first limiting segment 211 and the second limiting segment 212 are set at an angle, and a bayonet 213 is formed at the angle between them. This design allows the bayonet 213 to accommodate the connecting hole 11 and the corner portion 110 of the camera decorative ring 100 with different dimensional tolerances. Since dimensional deviations are unavoidable during the manufacturing process, the actual dimensions of the abutting side 111 of the connecting hole 11 and the corner portion 110 may fluctuate within a certain range, and the bayonet 213 formed by the angle has a certain amount of containment space.

[0045] In one embodiment, such as Figure 6 As shown, the surface of the contact side 111 is arc-shaped. This design ensures that when the latch 213 of the elastic part 21 contacts the contact side 111, it forms a line contact rather than a point or surface contact. Specifically, when the latch 213 of the elastic part 21 contacts the contact side 111 under the action of elastic force, the outer edges of the first limiting segment 211 and the second limiting segment 212 will form two parallel contact lines with different positions on the arc-shaped surface.

[0046] During assembly, since the curved mask has a certain curvature, when the elastic part 21 is slightly offset due to installation error or the size fluctuation of the camera decorative ring 100, the bayonet 213 can slide adaptively along the curved surface to ensure that a stable abutment force is always maintained.

[0047] In one embodiment, such as Figure 6 As shown, the connecting hole 11 also includes a straight side 113 opposite to the abutting side 111, and two inclined sides 112 connecting the abutting side 111 and the straight side 113. With this design, the guiding effect of the inclined sides 112 reduces the assembly difficulty, allowing operators to complete the mating of the elastic part 21 and the connecting hole 11 without precise alignment, thus improving assembly efficiency.

[0048] In one embodiment, the distance between the two inclined sides 112 gradually increases from the end closer to the abutting side 111 to the end closer to the straight side 113. With this design, the inclined side 112 guides the first limiting segment 211 and the second limiting segment 212, which facilitates the bayonet 213 to easily reach the position of the abutting side 111 of the connecting hole 11, thereby reducing the assembly difficulty.

[0049] In one embodiment, the angle between the elastic part 21 and the intermediate connecting section 23 is greater than 90° and less than 180°. This angle range ensures that the reverse elastic force applied by the elastic part 21 to the cover plate 1 is more in the expected direction. Taking 120° as an example, when the angle at the connection is set to 120°, the elastic part 21 will open outward in its natural state, forming an outward tension with the intermediate connecting section 23. When the elastic part 21 passes through the connecting hole 11 and abuts against the abutting side 111, this angle causes the deformation of the elastic part 21 to be mainly concentrated at the connection and the first limiting section 211 and the second limiting section 212 of the elastic part 21 itself. The direction of the elastic force can be accurately directed outward along the radial direction of the cover plate 1, ensuring that the reverse forces applied by the two elastic parts 21 form a stable equilibrium state. If the included angle is equal to 90°, the elastic part 21 is almost perpendicular to the intermediate connecting section 23. At this time, the elastic force is easily dispersed in the direction perpendicular to the shielding cover 1, resulting in insufficient radial force and the shielding cover 1 may become axially loose. If the included angle is equal to 180°, the elastic part 21 and the intermediate connecting section 23 are distributed in a straight line, and almost no radial elastic force can be generated, so the shielding cover 1 cannot be fixed.

[0050] In one embodiment, the elastic element 2 is a one-piece molded structure. In this embodiment, the intermediate connecting section 23, the extension section 22 of the elastic part 21, the first limiting section 211, the second limiting section 212, and other components are processed into an inseparable integral structure through a one-time molding process. This design eliminates connection gaps and assembly errors between components, and the connection between the intermediate connecting section 23 and the elastic part 21 will not loosen or break, making it durable and easy to manufacture.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
