Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone back cover processing equipment, specifically a mobile phone back cover spraying fixture. Background Technology

[0002] As an essential component of a mobile phone casing, the back cover is also a part that reflects the phone's aesthetic appeal. As people's aesthetic appreciation of mobile phones increases, a single color can lead to visual fatigue. Therefore, mobile phone back covers need to be painted with multiple colors. In current technology, when painting the back cover, equipment is needed to fix it in place. However, some equipment uses contact fixation against the inner wall of the back cover. If the edges of the back cover are thin, the contact fixation effect is not good, and the pressure against the surface of the back cover can easily cause scratches.

[0003] For example, the authorized patent document with application number CN202223125686.6 discloses a mobile phone back cover edge spraying fixture, which includes a fixture base, and the upper surface of the fixture base is provided with a base product conforming placement surface, and the upper part of the base product conforming placement surface is provided with a base product positioning block. The upper part of the fixture base is equipped with a plurality of spaced middle frames, and the upper and lower surfaces of the spaced middle frames are provided with middle frame product conforming surfaces, and the upper part of the middle frame product conforming surfaces is provided with middle frame product positioning blocks. The upper part of the spaced middle frames is equipped with a fixture cover plate, and the lower end surface of the fixture cover plate is provided with a cover plate product conforming surface. The fixture cover plate is provided with a cover plate locking hole, and the upper part of the cover plate locking hole is equipped with a locking rod, which passes through the spaced middle frames to the fixture base. The lower end of the locking rod is provided with a locking block, and the locking block is correspondingly matched with a locking hole provided in the base.

[0004] The aforementioned patent involves contacting and fixing the inner wall of the phone back cover. If the edge of the phone back cover is thin, the contact and fixing effect is not good. At the same time, it is easy to cause scratches when pressed against the surface of the phone back cover. Therefore, we need to provide a phone back cover spraying fixture. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4. This utility model provides a technical solution: a mobile phone back cover spraying fixture, comprising: A truncated cone 1, with an adsorption mechanism 2 installed inside the truncated cone 1 for fixing the back cover of the mobile phone; A base plate 3 is rotatably mounted on the surface of the frustum 1, and a drive mechanism 4 for adjusting the rotation bar of the frustum 1 is installed inside the base plate 3; Specifically, an adsorption mechanism 2 is set on the circular platform 1. The adsorption mechanism 2 adsorbs the bottom of the phone back cover and is adapted to the thinner edges of the phone back cover. Compared with the fixing method that abuts against the inner wall of the phone back cover, the adsorption mechanism 2 causes less wear on the surface of the phone back cover, protecting the appearance of the phone back cover. At the same time, it enables the phone back cover to rotate and adjust, which is convenient for subsequent spraying operations.

[0018] A frame 5 is fixedly installed on the top of the base plate 3, and a paint spraying part 6 for spraying the back cover of the mobile phone is set inside the frame 5. In this embodiment, the inner wall surface of the phone back cover to be sprayed is attached to the adsorption mechanism 2, first contacting the four adsorption seats 22. All four adsorption seats 22 are deformable rubber seats, providing initial adsorption for the phone back cover. Pulling the pull ring 205 causes the adjusting column 202 to move downwards. The two ring parts on the surface of the adjusting seat are located at the top and bottom of the connecting plate 201, respectively, thus causing the connecting plate 201 to move downwards. This controls the downward movement of the four rods, causing the piston 23 at the upper end of the rods to move downwards within the tube 21. Within the tube 21 and positioned at the top of the piston 23, a negative pressure is formed, firmly adsorbing the phone back cover. The connecting plate 201 is rotatably mounted on the surface of the adjusting column 202. Rotating the adjusting column 202 causes the threaded part 203 on the surface of the adjusting column 202 to be threaded onto the inner wall of the threaded cylinder 204, limiting and fixing the connecting plate 201, achieving firm adsorption of the phone back cover. The drive motor 41 is then activated, driving the drive gear 42 to rotate. The toothed ring 43 is driven to rotate, thereby controlling the truncated cone 1 to rotate on the base plate 3. The back cover of the mobile phone that is adsorbed can be rotated and adjusted, and spraying is carried out in conjunction with the sprayer 9.

[0019] The adsorption mechanism 2 includes four tubes 21 embedded in the top of the frustum 1. The top of each of the four tubes 21 is connected to an adsorption seat 22. A piston 23 is provided inside the tube 21. A pull rod 24 is fixedly installed at the bottom of the piston 23. A synchronizing element 20 is provided at the bottom of the four pull rods 24. The synchronizing element 20 is used for the four pull rods 24 to move synchronously. Specifically, the four adsorption seats 22 are all deformable rubber seats, which play a preliminary adsorption role on the back cover of the mobile phone. Pulling the pull ring 205 drives the adjusting column 202 to move down, and the synchronizing component 20 controls the four rods to move down. The piston 23 at the upper end of the rod moves down inside the tube 21. Inside the tube 21 and located at the top of the piston 23, a negative pressure is formed, which firmly adsorbs the back cover of the mobile phone.

[0020] Synchronizing component 20 includes a connecting plate 201 fixedly installed at the bottom of four rods. An adjusting column 202 is rotatably installed inside the connecting plate 201. A threaded part 203 is integrally machined on the surface of the adjusting seat. A threaded cylinder 204 is embedded in the bottom of the truncated cone 1. The threaded part 203 is threadedly installed on the inner wall of the threaded cylinder 204. A pull ring 205 is fixedly installed at the bottom of the adjusting column 202. Furthermore, by pulling the pull ring 205, the adjusting column 202 is moved downwards. The two ring parts on the surface of the adjusting seat are located at the top and bottom of the connecting plate 201, respectively, thereby moving the connecting plate 201 downwards and controlling the four rods to move downwards. The piston 23 at the upper end of the rod moves downwards inside the tube 21, so that the four pistons 23 can move synchronously for adjustment.

[0021] The drive mechanism 4 includes a drive motor 41 embedded in the base plate 3. The output end of the drive motor 41 is equipped with drive teeth 42. A toothed ring body 43 is fixedly installed on the surface of the frustum 1. The surface of the toothed ring body 43 meshes with the surface of the drive teeth 42. Two limiting rings 44 are provided on the surface of the frustum 1. The two limiting rings 44 are located at the top and bottom of the base plate 3, respectively. It is worth noting that starting the drive motor 41 drives the drive gear 42 to rotate, and the drive gear 42 drives the gear ring body 43 to rotate, thereby controlling the truncated cone 1 to rotate on the base plate 3. The back cover of the mobile phone that is adsorbed can be rotated and adjusted, and sprayed with the sprayer 9.

[0022] Each of the four pistons 23 has two annular grooves 7 on its surface. Each of the two annular grooves 7 has a sealing ring 8 inside it. The sealing ring 8 is a rubber ring and its surface is in close contact with the inner wall of the tube body 21. It should be noted that the sealing ring 8 is located in the annular groove 7, and the sealing ring 8 is a rubber ring, thereby increasing the friction and making the surface of the sealing ring 8 fit more tightly against the inner wall of the tube body 21.

[0023] The painting component 6 includes an output rod 61 rotatably mounted in the frame 5, an output motor 62 is mounted on one end of the output rod 61, a movable seat 63 is threaded onto the surface of the output rod 61, and a sprayer 9 is mounted on the surface of the movable seat 63. The starting output motor 62 drives the output rod 61, and the rotation of the output rod 61 drives the moving seat 63 to move, controlling the horizontal movement of the sprayer 9. This, combined with the rotation adjustment of the back cover of the mobile phone, increases the spraying range.

[0024] This device attaches the inner wall of the phone back cover to be sprayed onto the adsorption mechanism 2. It first contacts four adsorption seats 22, all of which are deformable rubber seats, providing initial adsorption for the phone back cover. Pulling the pull ring 205 causes the adjusting column 202 to move downwards. The two ring parts on the surface of the adjusting seat are located at the top and bottom of the connecting plate 201, respectively, thus causing the connecting plate 201 to move downwards. This controls the downward movement of the four rods, causing the piston 23 at the upper end of the rods to move downwards within the tube 21. Located at the top of the piston 23 within the tube 21, a negative pressure is created, firmly adsorbing the phone back cover. The connecting plate 201 is rotatably mounted on the surface of the adjusting column 202. Rotating the adjusting column 202 causes the threaded part 203 on the surface of the adjusting column 202 to be threaded onto the inner wall of the threaded cylinder 204, limiting and fixing the connecting plate 201, achieving a firm adsorption of the phone back cover. The drive motor 41 is then activated, driving the drive gear 42 to rotate. The toothed ring 43 rotates, thereby controlling the rotation of the frustum 1 on the base plate 3. This allows for the rotational adjustment of the adsorbed mobile phone back cover, facilitating spraying with the sprayer 9. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
