[0002] The SIM card tray is a common component of mobile phones, primarily housing the SIM card and SD card. Since the card cap is exposed outside the casing after installation, its top surface requires a high-gloss finish to achieve a mirror-like polish. Therefore, a polishing device is needed for processing. Existing polishing devices for SIM card trays cannot lift their polishing heads by tilting them up and down, resulting in poor flexibility. Furthermore, the small size of the SIM card tray makes it inconvenient for operators to handle.

[0003] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

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

[0017] like Figure 1 , Figure 2 , Figure 3, Figure 4 and Figure 5 As shown, a surface polishing device for processing mobile phone SIM card trays includes a frame, a connecting arm 1, and a polishing head 2. The connecting arm 1 has a connecting end 11 and a swing end 12. The connecting end 11 is connected to the frame, and the swing end 12 extends to the worktable. The polishing head 2 is movably connected to the swing end 12 for polishing the surface of the workpiece on the worktable. The connecting arm 1 is provided with a swing mechanism 3 for driving the polishing head 2 to swing up and down. The swing mechanism 3 includes a mounting base 31 fixedly connected to the connecting end 11, a rotating seat 34 rotatably connected to the swing end 12, and a drive cylinder 32 rotatably connected to the mounting base 31. A pull rod 341 extends vertically upward along the center of the rotating seat 34. The drive cylinder 32 is inclinedly disposed on the top of the mounting base 31, and the piston rod 33 of the drive cylinder 32 is rotatably connected to the top of the pull rod 341.

[0018] In this embodiment, the polishing head 2 includes a bracket 21, a motor 22, and a polishing disc 23. The bottom of the bracket 21 is fixedly connected to the side of the rotating base 34 away from the mounting base 31. A drive shaft 29 is rotatably connected to the bracket 21. The polishing disc 23 is fixedly connected to the lower part of the drive shaft 29. The motor 22 is mounted on the bracket 21, and its power end is connected to the drive shaft 29 via a synchronous belt 2012 assembly 201. Accordingly, the motor 22 drives the polishing disc 23 mounted on the drive shaft 29 to rotate at high speed. Under the combined action of the polishing disc 23 and the polishing agent, the polishing disc 23 rubs against the surface of the workpiece to be polished, thereby achieving the polishing effect.

[0019] In this embodiment, the synchronous belt 2012 assembly 201 includes a synchronous belt 2012, a first synchronous belt 2012 pulley 2011, and a second synchronous belt 2012 2013 pulley. The first synchronous belt 2012 pulley 2011 is fixedly connected to the power end of the motor 22; the second synchronous belt 2012 2013 pulley is fixedly connected to the upper part of the drive shaft 29; the synchronous belt 2012 is tensioned on the first synchronous belt 2012 pulley 2011 and the second synchronous belt 2012 2013 pulley.

[0020] In this embodiment, as Figure 4 and Figure 5As shown, a support ring 25 is also provided at the center of the polishing disc 23. Multiple equally spaced support portions 26 are formed at the bottom of the support ring 25. Each support portion 26 is a vertically positioned column at the top of the polishing disc 23. A water distribution plate 24 is fixedly connected to the top of the support ring 25. A water storage groove 2401 is formed circumferentially along the top of the water distribution plate 24. Water outlet holes 2402 are evenly distributed at the bottom of the water storage groove 2401. A hollow tubular structure 202 is installed inside the water outlet hole 2402, extending downwards and penetrating the support ring 25. Therefore, through the interaction of the water distribution plate 24 and the hollow tubular structure 202, water can be evenly distributed onto the polishing disc 23. Spraying water can reduce the temperature of the grinding area, preventing damage to the workpiece surface or affecting the grinding effect due to heat generated by friction.

[0021] Furthermore, a connecting plate 28 is fixedly connected to the drive shaft 29. One end of the connecting plate 28 extends above the water storage groove 2401 and has an assembly hole. A cooling water nozzle 27 is installed in the assembly hole. The cooling water nozzle is connected to a water source through a pipe. During operation, the cooling water nozzle 27 sprays water into the water storage groove 2401. The water falls into the water storage groove 2401 and flows into the tubular structure 202 through the water outlet 2402. After passing through the tubular structure 202, the water falls onto the polishing disc, cooling the polishing disc during grinding.

[0022] In summary, this application utilizes a drive cylinder 32 rotatably mounted on the connecting arm 1. The piston rod 33 of the drive cylinder 32 extends and retracts to drive the rotating seat 34 to rotate upwards or downwards, thereby causing the polishing head 2 to rotate upwards or downwards along with the rotating seat 34. When the polishing head 2 rotates upwards to a set angle, the problem of the polishing head 2 obstructing the view is solved, providing the operator with more space to pick up parts and improving the convenience of the operator in picking up parts.

[0023] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
