Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and in particular to a camera decorative ring spray shielding jig. Background Art

[0002] In the manufacturing process of consumer electronic devices (such as smartphones and tablets), camera bezels, as important exterior components, often require surface coating to achieve specific decorative effects and protective properties. However, the structure of camera bezels is often complex. In addition to the areas that require coating, there are also areas where coating must be avoided, such as the connection points with the device housing and around positioning holes.

[0003] In order to ensure the quality of spraying and prevent the paint from contaminating the spraying avoidance area, shielding fixtures are usually used in the prior art to block these areas. Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The traditional masking jig consists of five layers of masking plates and multiple fasteners. This design requires more raw materials, resulting in higher overall costs. Furthermore, during installation, operators must first stack and align the five layers of masking plates, ensuring that the positioning holes on each layer are perfectly aligned. Then, they must install the multiple fasteners one by one, repeatedly adjusting the positions to prevent the masking plates from shifting. For mass production, this installation method severely impacts assembly efficiency. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a camera decorative ring spray shielding fixture, aiming to solve the problems of high cost and complicated assembly and disassembly of the shielding fixture.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a camera decorative ring spray masking jig, comprising:

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

[0008] The elastic member comprises at least two elastic parts arranged opposite to each other;

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

[0010] Furthermore, the elastic parts are each provided with a bayonet for engaging with the connecting hole, and the bayonet abuts against one side of the connecting hole under the action of elastic force.

[0011] Furthermore, the elastic portion 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 with the bayonet, and the abutting side is aligned with the corner portion extending toward the center of the camera decorative ring, so that the bayonet abuts with the abutting side and the corner portion at the same time under the action of elastic force.

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

[0014] Furthermore, the connecting hole further 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 an end close to the abutting side to an end close to the straight side.

[0016] Furthermore, the elastic member includes a middle connecting section, both ends of the middle connecting section are connected to the elastic parts respectively, and the connection between the elastic parts and the middle connecting section is arranged at an angle.

[0017] Furthermore, the elastic portion further includes an extension segment, one end of the extension segment is connected to the first limiting segment, and the other end of the extension segment is connected to the middle connecting segment.

[0018] Furthermore, the elastic member is an integrally formed structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects: a camera decorative ring spray shielding jig includes a shielding cover and an elastic member, the shielding cover is arranged in the spray avoidance area of ​​the camera decorative ring spray surface, the shielding cover is provided with at least two connecting holes opposite to each other; the elastic member includes at least two elastic parts arranged opposite to each other; after the shielding cover is installed in place, the two elastic parts both pass through the camera decorative ring and are respectively provided in the two connecting holes, and the two elastic parts respectively apply elastic forces in opposite directions to the shielding cover to fix the shielding cover on the camera decorative ring. The jig can achieve precise shielding of the spray avoidance area only through the cooperation of the shielding cover and the elastic member, without the need for the traditional multi-layer stacked shielding plate structure and multiple fasteners, greatly reducing the number of parts and thus greatly reducing costs. At the same time, the shielding cover and the camera decorative ring can be automatically fixed by utilizing the reverse elastic force of the elastic part, making assembly and disassembly convenient and quick.

[0037] like Figures 3 to 7 As shown, an embodiment of the present invention provides a camera decorative ring spray shielding fixture, including a shielding cover 1 and an elastic member 2. The shielding cover 1 is arranged in the spray avoidance area of ​​the spray surface of the camera decorative ring 100, and the shielding cover 1 is provided with at least two connecting holes 11 opposite to each other; the elastic member 2 includes at least two elastic parts 21 arranged opposite to each other; after the shielding cover 1 is installed in place, the two elastic parts 21 pass through the camera decorative ring 100 and are respectively provided in the two connecting holes 11, and the two elastic parts 21 respectively apply elastic forces in opposite directions to the shielding cover 1 to fix the shielding cover 1 on the camera decorative ring 100.

[0038] The shielding cover 1 is made of a material with a certain structural strength, such as ABS plastic or aluminum alloy. Its shape is compatible with the spray avoidance area of ​​the camera decorative ring 100 to ensure the shielding seal. At least two connecting holes 11 are provided at the edges of the shielding cover 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 shielding cover 1.

[0039] The elastic member 2 is made of a material with excellent elastic recovery properties, such as spring steel. It includes a central connecting section 23 and two elastic portions 21 connected to each end of the central connecting section 23. The two elastic portions 21 are arranged opposite each other and at an angle to the connection with the central connecting section 23, giving the elastic member 2 an overall "U"-shaped frame structure. Each elastic portion 21 includes an extension section 22, a first limiting section 211, and a second limiting section 212, which are connected in sequence. One end of the extension section 22 is fixedly connected to the central connecting section 23, and the other end is connected at an angle to the first limiting section 211. The first limiting section 211 and the second limiting section 212 are arranged at a 120° angle, forming a snap-in 213 at the angle between them. This snap-in 213 is used to engage with the connection hole 11 on the shielding cover 1.

[0040] During the assembly process, the operator first places the shielding cover 1 on the spray-coated surface of the camera decorative ring 100, ensuring that the shielding cover 1 completely covers the spray-coated avoidance area. At this point, the abutting side 111 of the connecting hole 11 on the shielding cover 1 is aligned with the corner portion 110 extending toward the center of the camera decorative ring 100. Subsequently, the two elastic portions 21 of the elastic member 2 are passed through the hollow portion 120 of the camera decorative ring 100, and the retaining holes 213 of the elastic portions 21 are inserted into the corresponding connecting holes 11 of the shielding cover 1. During the insertion process, the two elastic parts 21 produce elastic deformation in opposite directions due to being squeezed. When the bayonet 213 completely enters the connecting hole 11, the elastic part 21 opens outward under the action of its own elastic restoring force. At this time, the bayonet 213 formed by the first limiting section 211 and the second limiting section 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 bayonet 213 will also form a double abutment with the corner part 110, so that the two elastic parts 21 respectively apply elastic forces in opposite directions to the shielding cover 1 (that is, tension radially outward along the shielding cover 1), thereby firmly fixing the shielding cover 1 on the camera decorative ring 100.

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

[0042] Through the ingenious cooperation between the shielding cover 1 and the elastic member 2, automatic fixation is achieved by utilizing the reverse elastic force of the elastic portion 21. Compared with the traditional structure in which multiple layers of shielding plates are stacked and fixed by fasteners such as screws and snaps, the use of parts is reduced, and the material cost and processing cost are greatly reduced. At the same time, the elastic snap-fit ​​fixing method greatly improves the efficiency of assembly and disassembly.

[0043] It should be noted that the number of surfaces of the camera decorative ring 100 that need to be sprayed varies depending on process requirements. Specifically, some camera decorative rings 100 only need to be sprayed on one surface (i.e., the spraying surface is located on the upper or lower surface of the camera decorative ring 100), while some camera decorative rings 100 need to be sprayed on two surfaces (i.e., the spraying surfaces are located on the upper and lower surfaces of the camera decorative ring 100). When only one surface needs to be sprayed, only one shielding cover plate 1 is required to cover the spraying avoidance area of ​​the spraying surface. When two surfaces need to be sprayed, only two shielding cover plates 1 are required to cover the spraying avoidance areas of the spraying surfaces. Compared with traditional jigs, the number of parts used is significantly reduced.

[0044] In one embodiment, the first limiting section 211 and the second limiting section 212 are arranged at an angle, and a notch 213 is formed at the angle between them. This angle allows the notch 213 to accommodate different dimensional tolerances of the connection hole 11 and the corner portion 110 of the camera decorative ring 100. Due to the inevitable dimensional deviations during the manufacturing process, the actual dimensions of the abutting side 111 of the connection hole 11 and the corner portion 110 may fluctuate within a certain range. The notch 213 formed by the angle provides a certain amount of accommodation space.

[0045] In one embodiment, if Figure 6 As shown, the surface of the abutting side 111 is an arcuate surface. This design ensures that when the retaining plate 213 of the elastic portion 21 contacts the abutting side 111, it forms a line contact fit rather than a point contact or surface contact. Specifically, when the retaining plate 213 of the elastic portion 21 contacts the abutting side 111 under the action of the elastic force, the outer edges of the first limiting section 211 and the second limiting section 212 form two parallel contact lines with different positions of the arcuate surface.

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

[0047] In one embodiment, if Figure 6 As shown, the connecting hole 11 further includes a straight side 113 opposite 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 assembly difficulty, allowing the operator to complete the mating of the elastic portion 21 and the connecting hole 11 without precise alignment, thereby improving assembly efficiency.

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

[0049] In one embodiment, the angle between the elastic portion 21 and the middle connecting section 23 at the connection is greater than 90° and less than 180°. This angle range can ensure that the reverse elastic force applied by the elastic portion 21 to the shielding cover 1 is more in line with the expected direction. Taking 120° as an example, when the angle at the connection is set to 120°, the elastic portion 21 will open outward in a natural state, forming an outward tension with the middle connecting section 23. When the elastic portion 21 passes through the connecting hole 11 and abuts against the abutting side 111, the angle causes the deformation of the elastic portion 21 to be mainly concentrated at the connection and the first limiting section 211 and the second limiting section 212 of the elastic portion 21 itself. The direction of the elastic force can be precisely radially outward along the shielding cover 1, ensuring that the reverse forces applied by the two elastic portions 21 form a stable equilibrium state. If the angle is equal to 90°, the elastic part 21 is almost perpendicular to the middle 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 angle is equal to 180°, the elastic part 21 and the middle connecting section 23 are distributed in a straight line, and almost no radial elastic force can be generated, and the shielding cover 1 cannot be fixed.

[0050] In one embodiment, the elastic member 2 is an integrally molded structure. Specifically, the intermediate connecting section 23, the extension section 22 of the elastic portion 21, the first retaining section 211, and the second retaining section 212 are formed into an integral, integral structure through a single molding process. This integrated design eliminates gaps and assembly errors between components, preventing loosening or breakage at the connection between the intermediate connecting section 23 and the elastic portion 21. This ensures durability and ease of manufacture.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
