Description

Technical Field

[0001] This utility model relates to the field of mobile phone manufacturing technology, and in particular to a polishing device for mobile phone manufacturing. Background Technology

[0002] As mobile phones become increasingly sophisticated, they are no longer limited to communication functions. They now possess various work and entertainment applications to meet people's work and entertainment needs. As an indispensable smart tool in people's daily lives and work, mobile phones play an increasingly important role. During the manufacturing process, the surfaces of parts such as the casing and cover need to be polished to ensure good phone quality. The polishing principle involves an electric motor driving a sponge or wool polishing disc to rotate at high speed. Due to the combined action of the polishing disc and polishing agent, friction is applied to the surface to be polished, thereby removing paint contamination, oxide layers, and shallow scratches.

[0003] A search revealed a patent with publication number CN209533045U entitled "A Polishing Device for Mobile Phone Shell Production." The technical problem it addresses is insufficient polishing fineness, resulting in metal powder that scratches the metal shell under the polishing wheel and causes powder to splatter everywhere. By using an adjustable atomizing nozzle connected to an external water pipe, water flows through the nozzle and is sprayed as a mist. The size of the water mist particles can be adjusted, and the water mist absorbs and carries away the metal powder, preventing damage to the metal shell under the polishing wheel's pressure. This results in finer polishing, eliminates powder splatter and cleaning difficulties, and improves the device's practicality and environmental friendliness. However, the following drawbacks still need to be addressed: when the grinding disc polishes mobile phone parts, the heat from the grinding disc, mobile phone parts, and worktable is not dissipated in time.

A cold source inlet and a heat source outlet are fixedly provided on the outer wall of one end of the heat exchange frame, and a diverter pipe is fixedly connected to the cold source inlet and outlet ends. A collector pipe is fixedly connected to the heat source outlet inlet end. Multiple sets of longitudinal heat exchange rods are fixedly arranged between the inner walls of both ends of the heat exchange frame, and multiple transverse heat exchange rods are fixedly arranged between the inner walls of both sides of the heat exchange frame, with the longitudinal and transverse heat exchange rods arranged in a crisscross pattern. A heat transfer plate is embedded in the bottom of the worktable, and multiple heat-conducting columns are fixedly installed at the bottom of the heat transfer plate.

[0008] Preferably, a fixing frame is fixedly installed on the upper end of the outer wall of the other end of the support platform, and a drive motor is fixedly installed on the outer wall of the fixing frame. A drive gear is fixedly installed on the output end of the drive motor, and the drive gear is located between the outer wall of the support platform and the inner wall of the fixing frame. The circumference of the drive gear meshes with two racks.

[0009] Preferably, the top of the two vacuum cleaner frames is provided with multiple through holes, and the bottom of the two vacuum cleaner frames is fixedly connected with a telescopic corrugated pipe.

[0010] Preferably, the cold source inlet is located at the bottom end of one side of the outer wall of the heat exchange frame, and the heat source outlet is located at the top end of the other side of the outer wall of the heat exchange frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model proposes a polishing device for mobile phone production. When the polishing and grinding components process mobile phone parts fixed at the top of the worktable, a heat exchange frame, a heat transfer plate, and multiple heat-conducting columns are provided at the bottom of the worktable. The heat exchange frame is filled with a flowing heat exchange fluid. Multiple sets of longitudinal heat exchange rods and multiple transverse heat exchange rods are arranged in a cross pattern inside the heat exchange frame. This allows the heat transfer plate to transfer the heat from the worktable to the multiple heat-conducting columns in a timely manner. Each heat-conducting column is inserted into the gap between the cross-arranged transverse and longitudinal heat exchange rods. The heat exchange fluid and the multiple transverse and longitudinal heat exchange rods exchange heat with the heat-conducting columns in a timely manner, so that the heat generated by the worktable during operation is transferred to the interior of the heat exchange frame in a timely manner. The flowing heat exchange fluid further exchanges heat with the interior of the heat exchange frame and transfers the heat in a timely manner, allowing the worktable to work stably for a long time.

[0015] 2. The present invention proposes a polishing device for mobile phone production, which includes a transmission gear, a U-shaped rack, two racks, a drive motor, and a drive gear on the outside of a support platform. When the drive motor is working, the drive gear drives the two racks to move closer together, causing the two U-shaped racks to move closer together, which in turn drives the two transmission gears to rotate in opposite directions. This causes the two dust collection frames to rotate from a horizontal state to an inclined or even vertical state, which facilitates the timely collection of dust from the polishing and grinding components and the area around the workbench, preventing dust from affecting mobile phone production and worker health, and also helps to enhance the heat dissipation of the workbench.

Each heat conduction column 17 is inserted into the gap between the transverse heat exchange rods 24 and the longitudinal heat exchange rods 23 arranged in a cross pattern.

[0022] In this utility model, the other end of the two dust collection frames 3 passes through and extends to the outer side of the outer wall of the support platform 1. The other end of the two dust collection frames 3 is fixedly installed with a transmission gear 12. Each transmission gear 12 has a U-shaped toothed rod 13 meshing at the top of its circumference. A rack 14 is fixedly installed on the bottom of one side of the outer wall of one U-shaped toothed rod 13 and the top of the other side of the outer wall of the other U-shaped toothed rod 13.

[0023] A fixed frame 9 is fixedly installed on the upper end of the outer wall of the other end of the support platform 1, and a drive motor 10 is fixedly installed on the outer wall of the fixed frame 9. A drive gear 11 is fixedly installed on the output end of the drive motor 10, and the drive gear 11 is located between the outer wall of the support platform 1 and the inner wall of the fixed frame 9. The circumference of the drive gear 11 meshes with two racks 14.

[0024] The top of the two vacuum baskets 3 are provided with multiple through holes, and the bottom of the two vacuum baskets 3 are fixedly connected with telescopic corrugated pipes.

[0025] The cold source inlet 18 is located at the bottom of one side of the outer wall of the heat exchange frame 4, and the heat source outlet 19 is located at the top of the other side of the outer wall of the heat exchange frame 4. Both the cold source inlet 18 and the heat source outlet 19 are made of heat insulation material, which helps the cold source to be evenly distributed inside the heat exchange frame 4.

[0026] The heat exchange frame 4 has four insertion holes 20 at the top corners, and the workbench 5 has four fixed insertion rods 15 at the bottom corners. Each row of insertion holes 20 matches the insertion rods 15, making the installation and disassembly of the workbench 5 and the heat exchange frame 4 convenient and quick.

[0028] Working principle: When the polishing and grinding assembly 8 processes the mobile phone parts fixed at the top of the worktable 5, the worktable 5 is equipped with a heat exchange frame 4, a heat transfer plate 16, and multiple heat-conducting columns 17 at its bottom. The heat exchange frame 4 is filled with a flowing heat exchange fluid.

Each heat-conducting column 17 is inserted into the gap between the transverse heat exchange rods 24 and the longitudinal heat exchange rods 23. The heat exchange fluid and the multiple transverse heat exchange rods 24 and the multiple sets of longitudinal heat exchange rods 23 exchange heat with the heat-conducting columns 17 in a timely manner. This allows the heat generated by the worktable 5 during operation to be transferred to the interior of the heat exchange frame 4 in a timely manner. The flowing heat exchange fluid exchanges heat with the interior of the heat exchange frame 4 again and transfers the heat in a timely manner, allowing the worktable 5 to work stably for a long time.

[0029] The support platform 1 is equipped with a transmission gear 12, a U-shaped rack 13, two racks 14, a drive motor 10, and a drive gear 11. When the drive motor 10 is working, the drive gear 11 drives the two racks 14 to move closer to each other, causing the two U-shaped racks 13 to move closer to each other, which in turn drives the two transmission gears 12 to rotate in opposite directions. This causes the two dust collection frames 3 to rotate from a horizontal state to an inclined or even vertical state, which facilitates the timely collection of dust around the polishing and grinding components 8 and the workbench 5, preventing dust from affecting mobile phone production and worker health, and also helps to enhance the heat dissipation of the workbench 5.
