Description

Technical Field

[0001] This utility model relates to the field of mobile phone manufacturing technology, and in particular to a mobile phone mid-frame spraying fixture. Background Technology

[0002] In the mobile phone manufacturing process, the spraying of the mid-frame is a key process to ensure the product's appearance quality and protective performance. The main function of the spraying fixture is to fix the mid-frame of the mobile phone and ensure that it remains stable during the spraying process, avoiding problems such as uneven coating, missed spraying, or inconsistent thickness caused by shaking or displacement.

[0003] Most common spraying fixtures on the market adopt a fixed structure. Their clamping range and shape are usually designed for a single model of mobile phone frame, which has poor versatility. When producing frames of different sizes or shapes, the corresponding fixture modules must be replaced, which not only increases the time for model change and debugging, but also leads to an increase in fixture management costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a mobile phone mid-frame spraying fixture.

[0005] Therefore, this utility model provides a mobile phone mid-frame spraying fixture, including a tray. The tray has an internal telescopic groove, and two telescopic plates are installed inside the telescopic groove. The bottom of each of the two telescopic plates has a linkage groove, and there are two linkage grooves in each of them. A support plate is fixedly connected to the outer wall of the tray, and there are multiple support plates in each of them. A bidirectional lead screw is movably connected to the inner wall of the tray. An adjusting motor is installed inside the right support plate. The output end of the adjusting motor is fixedly connected to one end of the bidirectional lead screw. A movable plate is threadedly connected to the outer wall of the bidirectional lead screw, and there are two movable plates in each of them. A connecting rod is fixedly connected to the top of each movable plate, and there are two connecting rods in each of them. A connecting groove is opened at the top of the inner wall of the tray, and there are two connecting grooves in each of them. The connecting rod extends through the connecting groove and into the interior of the corresponding linkage groove.

[0006] Preferably, the inner wall of the tray has a limiting groove, and there are two limiting grooves. The two ends of the movable plate are movably connected to pulleys, and the pulleys are located inside the limiting grooves.

[0007] Preferably, the outer wall of the support plate is provided with an anti-slip pad, and the telescopic plate is located on the outer wall of the telescopic plate on the side away from the tray.

[0008] Preferably, the bottom of the tray is provided with a base, and a rotary motor is installed inside the base. The output end of the rotary motor is fixedly connected to a drive bevel gear. The bottom of the tray is fixedly connected to a rotating plate by bolts. The bottom of the rotating plate is fixedly connected to a rotating shaft. The bottom of the rotating shaft extends into the interior of the base and is fixedly connected to a driven bevel gear. The outer wall of the driven bevel gear meshes with the outer wall of the drive bevel gear. A positioning ring is fixedly connected to the outer wall of the rotating shaft outside the base.

[0009] Preferably, a bearing is installed on the top of the base, the rotating shaft is fixedly connected to the inner ring of the bearing, and a sealing plate is fixedly connected to the outer wall of the base by bolts.

[0010] Preferably, the outer wall of the base is fixedly connected with a fixing block, and there are multiple fixing blocks; the bottom of the base is provided with a shock-absorbing pad; and the outer wall of the base is provided with a heat dissipation groove, and there are multiple heat dissipation grooves.

[0011] This utility model provides a mobile phone mid-frame spraying fixture, which has the following beneficial effects:

[0012] (1) The fixture of this utility model is equipped with a linkage mechanism of a bidirectional lead screw, a moving plate and a connecting rod. When the adjustment motor runs, it drives the bidirectional lead screw to rotate. The positive and negative thread characteristics of the bidirectional lead screw drive the two moving plates to move synchronously in opposite directions. The connecting rod fixed on the moving plate passes through the connecting groove and inserts into the linkage groove of the telescopic plate, accurately transmitting the linear motion of the moving plate to the telescopic plate, so that the two telescopic plates can extend outward or retract inward at the same time. The extension end of the telescopic plate adopts a contour-following design, which can closely fit the inner wall contour of the mobile phone frame. The evenly distributed clamping force achieves stable fixation of the frame. The rolling guide structure of the pulley in the limiting groove effectively eliminates the frictional resistance during the movement, ensuring that the entire adjustment process is smooth and free of jamming. The anti-slip pad on the surface of the support plate is made of high friction coefficient silicone material, which forms reliable contact with the outer wall of the frame, further enhancing the clamping stability and preventing slippage. This innovative structure allows the fixture to quickly adapt to mobile phone frames of different sizes, significantly improving the versatility and production efficiency of the fixture.

[0013] (2) By setting up a rotary motor, bevel gear transmission mechanism and rotating plate, the tray can rotate 360°, enabling the spraying operation to be carried out from multiple angles, which significantly improves the uniformity of the spraying coverage. The design of bearings and positioning rings ensures the smooth and reliable rotation process. The shock-absorbing pads of the base effectively absorb the vibration of the equipment, and the heat dissipation grooves ensure the heat dissipation of the motor. These designs together improve the operating stability and service life of the equipment, while reducing maintenance costs. Attached Figure Description

The output end of the adjusting motor 7 is fixedly connected to one end of the bidirectional lead screw 6. A sliding contact is threaded onto the outer wall of the bidirectional lead screw 6. There are two movable plates 8. The top of the movable plate 8 is fixedly connected to a linkage rod 9. There are two linkage rods 9. The top of the inner wall of the tray 1 is provided with a connecting groove 10. There are two connecting grooves 10. The linkage rod 9 extends through the connecting groove 10 to the interior of the corresponding linkage groove 4. The inner wall of the tray 1 is provided with a limiting groove 11. There are two limiting grooves 11. The two ends of the movable plate 8 are movably connected to pulleys 12. The pulleys 12 are located inside the limiting grooves 11. The outer wall of the support plate 5 is provided with an anti-slip pad 13. The telescopic plate 3 is located on the outer wall of the telescopic plate 3 away from the tray 1.

[0025] The motor 7 is adjusted to drive the bidirectional lead screw 6 to rotate, which in turn drives the two moving plates 8 to move in opposite directions through the screw thread. The connecting rod 9 on the moving plate 8 transmits the motion to the telescopic plate 3 through the connecting groove 10, causing the two telescopic plates 3 to extend outwards respectively, thereby clamping the middle frame from the inner wall of the phone frame. The pulley 12 rolls along the limiting groove 11 to ensure smooth movement. The anti-slip pad 13 of the support plate 5 enhances the clamping stability, making the clamp applicable to different specifications of phone frames and improving its applicability.

[0027] The rotating motor 15 inside the base 14 drives the rotating shaft 18 and the rotating plate 17 to achieve a 360° rotation of the tray 1 through the meshing of the driving bevel gear 16 and the driven bevel gear 19. After the outer wall of the mobile phone frame is sprayed, the rotating plate 17 stops rotating. Then, the next mobile phone frame is placed in, and the rotating plate 17 drives the tray 1 to rotate back to its position in the opposite direction. The above operation process can be repeated. The bearing 21 provides support, while the positioning ring 20 restricts axial displacement, and a sealing plate 22 is set to protect the rotating motor 15.
