Description

Technical Field

[0001] The present application relates to the field of mobile phone glass spraying technology, in particular to a 3D mobile phone curved glass ink spraying jig. Background Art

[0002] In recent years, with the continuous upgrading of smartphones, the pursuit of aesthetics and feel has led to a gradual transition in the design of smartphone back covers from 2D or 2.5D glass covers to 3D glass covers. Currently, to produce the 3D glass covers desired by users, most manufacturers use spray coating to color the 3D glass covers. Some 3D glass back covers are coated with ink to preserve the colorless transparency of the glass near the camera hole.

[0003] Existing ink spraying jigs for curved 3D mobile phone glass offer poor clamping performance. The clamping plate angle cannot automatically adjust to the curvature of the glass, leading to gaps and misalignment. This prevents the clamping plate from fitting tightly against the glass surface, causing ink to accumulate or leak on the curved surface. Furthermore, the clamping plate's grip on the glass is difficult to control, increasing the risk of glass damage due to improper mechanical clamping. Therefore, a new ink spraying jig for curved 3D mobile phone glass was proposed to address these issues. Summary of the Invention

[0004] In this embodiment, a 3D mobile phone curved glass ink spraying jig is provided to solve the problem of poor clamping effect on the curved glass during use, inability to automatically adjust the angle of the clamping plate according to the curvature of the curved glass, prone to gaps and misalignment, resulting in the clamping plate and the glass surface not being able to fit tightly, causing ink accumulation or omission on the curved surface. At the same time, the force of the clamping plate when clamping the glass is difficult to control, increasing the risk of glass damage due to improper mechanical clamping.

[0005] According to one aspect of the present application, a 3D mobile phone curved glass ink spraying jig is provided, comprising a base and a fixed seat, wherein two mounting frames are fixed on the fixed seat, and both mounting frames are provided with a fixing assembly, wherein the fixing assembly comprises a screw, a disc wheel, a movable plate and a rotating plate, the internal thread of the mounting frame is connected to the screw, the top end of the screw is fixedly mounted with a disc wheel, the bottom end of the screw is rotatably connected to the movable plate through a bearing, the bottom end of the movable plate is rotatably connected to the rotating plate, the rotating plate is rotatably connected to two connecting plates, the internal sliding connection of the movable plate is connected to two connecting rods, and the top ends of the two connecting rods are fixedly mounted with limiting plates.

[0006] Furthermore, anti-slip pads are provided on both rotating plates.

[0010] Furthermore, a connecting seat is fixedly installed on the bottom end of the fixing seat, a rotating sleeve is threadedly connected to the connecting seat, a universal ball is fixedly installed on the base, and the universal ball passes through the rotating sleeve.

[0011] Furthermore, a mounting groove is provided inside the base, and a rotating rod is rotatably connected to the inside of the mounting groove through a bearing. Both ends of the rotating rod extend to the outer end of the base and a hand wheel is fixedly installed thereon.

[0012] Furthermore, two driving gears are sleeved on the rotating rod, a T-shaped slot is opened inside the base, a threaded rod is rotatably connected to the inside of the base through a bearing, the bottom end of the threaded rod extends to the internal thread of the T-shaped slot and is connected to a fixed cylinder, and a suction cup is fixedly installed at the bottom end of the fixed cylinder.

[0013] Furthermore, four sliding grooves are opened on the inner wall of the T-shaped groove, and four sliding blocks are fixedly installed on the fixed cylinder, and the sliding blocks are all slidably connected to the sliding grooves.

[0014] Furthermore, driven gears are fixedly mounted on the top ends of the two threaded rods, and the two driven gears are meshedly connected with the driving gear.

[0015] In the above-mentioned embodiment of the present application, by providing a fixing component and rotating the disc wheel, the rotating plate drives the anti-slip pad to closely fit the inner side of the curved glass under the cooperation of the spring. The rotating plate can automatically adjust according to the curvature of the curved glass, ensuring that the spraying jig is closely fitted to the glass surface, reducing gaps and misalignment during the spraying process, helping to achieve uniform spraying, avoiding accumulation or omission of ink on the curved surface, improving the accuracy and consistency of spraying, and at the same time avoiding excessive pressure or scratches on the glass, effectively protecting the smoothness and integrity of the glass surface, and helping to reduce the risk of glass damage caused by improper mechanical clamping during the spraying process;

[0017] By rotating the rotating sleeve, the rotating sleeve moves up and down while rotating, and the rotating sleeve drives the damping pad and the universal ball to move closer or farther away, so that the friction between the damping pad and the universal ball increases or decreases, thereby facilitating the adjustment of the damping size of the rotation, so that the curved glass can be freely rotated in multiple directions to meet the spraying requirements of different angles and directions. At the same time, the rotation angle and position of the curved glass can be precisely controlled to ensure the accuracy and consistency of the spraying, and to ensure that the ink is evenly sprayed on the glass surface to avoid unevenness or missing coating.
