[0002] Currently, during the production process of mobile phone case frames, a layer of paint is usually sprayed on the sides after the machining is completed to improve the surface quality of the mobile phone case frame.
[0003] In the existing technology, there are already stacking spraying fixtures for clamping multiple phone case frames, which can spray multiple phone case frames at the same time, resulting in not only good spraying effect but also very high efficiency.
[0004] However, existing stacking spraying fixtures often stack a large number of phone cases, which makes the center of gravity of the entire stacking spraying fixture high. Moreover, when the stacking spraying fixture is installed on the rotating shaft, it is easy to misinstall it, which often causes rotational shaking during rotation, resulting in uneven spraying and affecting product quality.

[0028] Please see Figures 1-4 A rotating overlay spraying fixture for spraying the middle frame of a mobile phone (not shown) includes a clamping assembly 10 and a rotating assembly (not shown).
[0029] The clamping assembly 10 includes a middle frame cover plate 11, several middle frame fixing plates 12, and a middle frame base 13. The middle frame cover plate 11 is disposed above the middle frame base 13, and the several middle frame fixing plates 12 are located between the middle frame base 13 and the middle frame cover plate 11. The middle frame of the mobile phone is clamped between any two adjacent middle frame cover plates 11, several middle frame fixing plates 12, and middle frame base 13. The middle frame base 13 is provided with a mounting seat 131 protruding downwards, and the mounting seat 131 is provided with an insertion groove 132 recessed upwards.
[0030] The rotating assembly includes a rotating shaft 20 and a drive device (not shown). The upper end of the rotating shaft 20 is inserted into the insertion slot 132, and the lower end of the rotating shaft 20 is connected to the drive device. The upper end of the rotating shaft 20 is provided with a retaining structure 21. The end of the retaining structure 21 protrudes outward in the horizontal direction. The mounting base 131 is recessed upward with a retaining groove 133 that cooperates with the retaining structure 21. The retaining structure 21 is retained in the retaining groove 133.
[0031] The mounting base 131 extends obliquely downward within the retaining groove 133 and has a buckle 134. The retaining structure 21 has a snap-fit groove 211 that passes through the buckle 134, and the buckle 134 can be snapped into the snap-fit groove 211.
[0032] The rotary overlay spraying fixture provided in this embodiment of the utility model, through the cooperation of the middle frame cover plate 11, several middle frame fixing plates 12, and middle frame base 13, achieves compact clamping of several mobile phone middle frames, while improving spraying efficiency; through the cooperation of the insertion groove 132 with the rotating shaft 20, and the clamping groove 133 with the clamping structure 21, the rotating shaft 20 can drive the clamping assembly 10 to rotate, realizing rotation during the spraying of the mobile phone middle frame, making the spraying more uniform; through the cooperation of the buckle 134 with the buckle groove 211, on the one hand, it ensures that the clamping assembly 10 can be installed in place when installed on the rotating shaft 20, thereby preventing the clamping assembly 10 from shaking during rotation due to improper installation, ensuring the quality of the mobile phone middle frame spraying, and on the other hand, it plays an anti-detachment role, preventing the clamping assembly 10 from falling off during rotation.
[0033] Please see Figure 4 More specifically, the retaining groove 133 is connected to the insertion groove 132 so that when the rotating shaft 20 is inserted into the insertion groove 132 of the mounting base 131, the retaining structure 21 can cooperate with the retaining groove 133 so that the rotating shaft 20 can drive the clamping assembly 10 to rotate.
[0034] Please see Figure 5 and Figure 7 Furthermore, the buckle 134 includes a connecting portion 135 and a fastening portion 136. The upper end of the connecting portion 135 is connected to the mounting base 131, and the lower end of the connecting portion 135 is connected to the fastening portion 136. The fastening portion 136 can be fastened into the fastening groove 211. When the buckle 134 is fastened into the fastening groove 211, the connecting portion 135 passes through the fastening groove 211, and the fastening portion 136 abuts against the lower edge of the fastening groove 211, so as to realize the installation of the clamping assembly 10 and the anti-detachment function.
[0035] More specifically, the connecting portion 135 is inclined outward and has elasticity. The fastening portion 136 has an abutment surface 137 and a guide slope 138, with the abutment surface 137 contacting the guide slope 138. The abutment surface 137 is on the same plane as the horizontal plane and serves to prevent detachment.
[0036] During the installation of the clamping assembly 10 onto the rotating shaft 20, as the fastening part 136 gradually penetrates into the fastening groove 211, the guide slope 138 of the fastening part 136 abuts against the upper edge of the fastening groove 211, causing the connecting part 135 to bend inward. Then, the buckle 134 slides into the fastening groove 211 along the guide slope 138. After the fastening part 136 passes through the fastening groove 211, the connecting part 135 returns to its original shape due to elasticity, and the abutting surface 137 of the fastening part 136 abuts against the lower edge of the fastening groove 211. At this time, the clamping assembly 10 is installed in place. When it is necessary to disassemble the clamping assembly 10, the two buckles 134 are squeezed to bend the connecting part 135 inward, so that the fastening part 136 can disengage from the fastening groove 211, thus completing the disassembly of the clamping assembly 10.
[0037] More specifically, the guide slope 138 can be a straight surface or an arc surface. In this embodiment, the guide slope 138 is a straight surface.
[0038] Please see Figure 7 In this embodiment, the retaining structure 21 is a retaining pin 212, which is detachably mounted horizontally through the rotating shaft 20. Both ends of the retaining pin 212 protrude outwards from the sidewalls of the rotating shaft 20, and a fastening groove 211 is formed on the retaining pin 212. If the retaining pin 212 wears out due to long-term operation, it can be directly replaced, avoiding the need to directly replace the rotating shaft 20, thereby reducing maintenance costs.
[0039] Please see Figure 8 In another embodiment, the holding structure 21 consists of two symmetrically arranged holding posts 213 on the rotating shaft 20. The holding posts 213 are integrally formed with the rotating shaft 20, and the fastening groove 211 is formed on the holding posts 213.
[0040] Please see Figure 4 The mounting base 131 and the middle frame base 13 are integrally formed. Several reinforcing ribs 139 are provided at the connection between the mounting base 131 and the middle frame base 13, and these ribs 139 are evenly distributed around the mounting base 131. In this embodiment, four reinforcing ribs 139 are evenly distributed around the mounting base 131. The integral formation of the mounting base 131 and the middle frame base 13, along with the reinforcing ribs 139, enhances the connection strength between the mounting base 131 and the middle frame base 13, thereby improving the stability of the clamping assembly 10 and reducing the risk of the clamping assembly 10 shaking during rotation.
[0041] Please see Figure 1 and Figure 2The clamping assembly 10 also includes at least one pin 14, which passes through the middle frame cover plate 11, several middle frame fixing plates 12 and middle frame base 13 from top to bottom. The pin 14 is used to prevent the middle frame cover plate 11, several middle frame fixing plates 12 and middle frame base 13 from loosening, thereby preventing the mobile phone middle frame from loosening in the clamping assembly 10, reducing the instability of the center of gravity of the clamping assembly 10 during rotation, and keeping the rotating stacking spray fixture stable and not shaking during rotation.
[0042] Please see Figure 6 The middle frame fixing plate 12 and the middle frame base 13 are respectively provided with positioning structures 30 for positioning the middle frame of the mobile phone. The positioning structures 30 cooperate with the middle frame of the mobile phone to fix the middle frame of the mobile phone. The positioning structures 30 prevent the middle frame of the mobile phone from becoming loose in the clamping assembly 10, so as to reduce the instability of the center of gravity of the clamping assembly 10 during rotation.
[0043] The advantages of the rotary overlay spraying fixture provided by this utility model include:
[0044] (1) It can ensure that the clamping components are installed in place and play a role in preventing them from falling off.
[0045] (2) Keep the rotating stacking spray fixture stable and without shaking during the rotation process to ensure the quality of the mobile phone frame spraying.
[0046] 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 variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
