Description

Technical Field

[0001] This utility model relates to the field of mobile phone back cover polishing technology, specifically a polishing device for mobile phone back covers. Background Technology

[0002] The back cover of a mobile phone, also known as the phone back panel, is the cover plate on the back of the phone's casing. It protects the internal components and enhances the phone's appearance. The materials and styles of back covers vary between different brands and models. A crucial step in the production of the phone back cover is polishing, which aims to give it a high gloss finish, facilitating further production.

[0003] According to the polishing equipment for producing mobile phone back covers with application number CN202223265344.4, it is mentioned that: "It includes a base, a support frame is fixedly connected to one side of the top of the base, a protective shell is provided at the top of the base, and a worktable is provided at the top of the protective shell. This polishing equipment for producing mobile phone back covers is equipped with a connecting shaft, a stepper motor, a limit rod, a rotating shaft, a driven gear, and a drive gear. When the stepper motor is started, the stepper motor drives the drive gear to rotate through the rotating shaft. The rotation of the drive gear causes the driven gear and the connecting shaft to rotate the worktable. The rotation of the worktable facilitates the polishing of the mobile phone back cover inside the placement slot by the polishing disc. It allows the replacement of the mobile phone back cover on the other side while polishing the mobile phone back cover, thereby improving processing efficiency. It solves the problem that the worktable is inconvenient to rotate, making it inconvenient to polish the mobile phone back cover inside the placement slot, resulting in low work efficiency."

[0004] Based on the patent technologies retrieved above, and after conducting specific simulations, we discovered that the technology still has certain shortcomings:

[0005] 1. Although structures such as push rods were used to push the phone back cover out of the placement slot, it is still necessary for staff to manually remove the polished phone back cover from the placement slot, which is a rather cumbersome operation.

[0006] Second, although a dust extraction structure was used to remove the dust generated during the polishing process, it could only extract dust from localized areas. Dust far from the dust extraction port was difficult to remove in time, and the dust that was not removed in time was easy to disperse in the air, thus causing pollution in the workshop.

[0007] Therefore, in response to some problems existing in the existing technology, we have designed a polishing device for the back cover of mobile phones. Utility Model Content

The servo motor is installed on one side of the support plate and a lead screw is fixed on the power output shaft. The lead screw is threaded through the slider and rotatably connected to the other side of the inner wall of the groove.

[0011] As a further embodiment of this utility model: a fixing plate is welded to the front of the slider one, and a slider two driven by a servo motor three is slidably connected in the groove at the bottom of the fixing plate. A lead screw two is fixed on the power output shaft of the servo motor three.

A cylinder is installed at the bottom of the slider two, and a polishing motor is installed on the power output shaft at the bottom of the cylinder. A polishing wheel is detachably installed on the power output shaft at the bottom of the polishing motor.

[0012] As a further embodiment of this utility model: a shielding frame is fixed at the top of the fixed base and above the conveyor belt. Dust collection hoods are installed at equal intervals on both sides of the inner wall of the shielding frame. The air outlets of multiple dust collection hoods are connected to dust collection pipes. The air outlets of the dust collection pipes are connected to dust collection pipes. The air outlets of the dust collection pipes are connected to a first guide pipe. The air outlet of the first guide pipe passes through the fixed base and is connected to a second guide pipe. The air outlet of the second guide pipe is connected to an outlet pipe. The air outlet of the outlet pipe is connected to a filter box.

[0013] As a further embodiment of this utility model: the top of the filter box is sealed with a sealing cover, the air outlet of the filter box is connected to a dust collector fan through a connecting pipe, positioning blocks are fixed at equal intervals on both sides of the inner wall of the filter box, and a filter plate is inserted between the two positioning blocks on both sides of the inner wall of the filter box, and three filter plates are inserted inside the filter box; the filter box and the dust collector fan are both installed in the groove opened at the bottom of the inner cavity of the fixed base.

[0014] As a further embodiment of this utility model: the surfaces of the three filter plates are all provided with filter screens, and the mesh size of the filter screens decreases sequentially from the air outlet direction of the outlet pipe to the air inlet direction of the connecting pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This application, through its designed fixed base, conveyor belt, storage slot, ejection hole, transmission component, ejection block, and collection frame, effectively transports the mobile phone back cover to be polished to the shielding frame via the conveyor belt, and performs the polishing operation. After polishing, the continuous conveying of the conveyor belt, combined with the rotation of the rotating roller and the ejection action of the ejection block, ejects the polished mobile phone back cover from the storage slot and drops it into the collection frame. This allows the device to automatically remove the polished mobile phone back cover, reducing the number of steps required by the operator, improving processing efficiency, and allowing the operator to complete the polishing and unloading work simply by placing the mobile phone back cover beside the device. This technology has better practicality than existing technologies.

[0019] 2. This application, through the shielding frame set at the polishing position, and the dust suction hood, multiple pipes, filter box, and dust suction fan used in conjunction with the shielding frame, enables the polishing process to be carried out inside the shielding frame, which can effectively block the drifting dust and limit the dust drift range. In conjunction with the dust suction hood set on both sides inside the shielding frame, it can also perform multi-position dust suction inside the shielding frame, thereby better sucking up and filtering the dust generated during the polishing process and reducing the possibility of dust drifting into the workshop.

[0030] 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.

[0031] Please see Figure 1-8A polishing device for a mobile phone back cover includes a fixed base 1 and a mobile phone back cover 27. The top of the fixed base 1 has a groove with one side open, and a transmission belt 2 driven by a transmission component is disposed in the groove. Placement slots 3 are evenly spaced on the surface of the transmission belt 2, and ejection holes 301 are formed in the inner bottom wall of the placement slots 3. The mobile phone back cover 27 is placed inside the placement slots 3, and the top of the mobile phone back cover 27 protrudes from the transmission belt 2. The transmission component includes a servo motor 5 mounted on the side of the fixed base 1. The transmission connects rotating roller 601 and rotating roller 19 on both sides inside the conveyor belt 2. A helical wheel 7 is mounted on the power output shaft of servo motor 5. A drive shaft 6 is fixed inside rotating roller 601, with one end rotatably connected to the inner wall of the groove, and the other end extending through the fixed base 1, also equipped with a helical wheel 7. The two helical wheels 7 are connected by a belt drive. A drive shaft 18 is fixed inside rotating roller 19, with both ends rotatably connected to the inner wall of the groove on both sides. The power output shaft of servo motor 5 rotates via a belt-driven I-beam 7 connected to it, thereby driving drive shaft 6 to rotate, which in turn drives rotating roller 601 to rotate, achieving the purpose of driving transmission belt 2. Simultaneously, it can drive rotating roller 19 to rotate via drive shaft 18, achieving stable transmission of transmission belt 2. Ejection blocks 1901 are fixed on both sides of rotating roller 19 at positions corresponding to ejection holes 301. A collection frame 1 is also fixed on the left side of the fixed base 1. 5. The top of the collection frame 15 corresponds to the left opening of the groove. The size of the ejector block 1901 is smaller than the ejector hole 301. The side of the ejector block 1901 away from the rotating roller 19 is designed as an arc surface. The ejector block 1901 can pass through the ejector hole 301 and be placed in the storage groove 3. Both ejector blocks 1901 rotate with the rotation of the rotating roller 19, so that the arc surface of the ejector block 1901 can enter the storage groove 3 from the ejector hole 301, thereby ejecting the polished mobile phone back cover 27 in the storage groove 3.

[0032] In this embodiment, please refer to Figure 1-4A support plate 8 is fixed to the top back of the fixed base 1. A slider 9 driven by a servo motor 2 10 is slidably connected in the groove on the front of the support plate 8. The servo motor 2 10 is installed on one side of the support plate 8 and a lead screw 11 is fixed on the power output shaft. The lead screw 11 is threaded through the slider 9 and rotatably connected to the other side of the inner wall of the groove. A fixing plate 12 is welded to the front of the slider 9. A slider 2 1201 driven by a servo motor 3 13 is slidably connected in the groove at the bottom of the fixing plate 12. A lead screw 2 1301 is fixed on the power output shaft of the servo motor 3 13. The lead screw 2 1301 is threaded through the slider 2 1201 and rotatably connected to the other side of the inner wall of the groove. A cylinder 14 is installed at the bottom of the slider 2 1201. A polishing motor 28 is installed on the power output shaft at the bottom of the cylinder 14. A polishing wheel 1401 is detachably installed on the power output shaft at the bottom of the polishing motor 28.

[0033] Specifically, through the designed servo motor 210, servo motor 313, and polishing motor 28, the polishing wheel 1401 can be adjusted laterally by servo motor 210, and adjusted longitudinally by servo motor 313. This allows the position of the polishing wheel 1401 to be adjusted in real time according to polishing requirements. The polishing motor 28 drives the polishing wheel 1401 to rotate, thus polishing the back cover 27 of the mobile phone. The polishing wheel 1401 is detachably installed at the bottom of the polishing motor 28, which facilitates the replacement of polishing wheels 1401 that have been used for a long time.

[0034] In this embodiment, please refer to Figure 1-8 A baffle frame 4 is fixed at the top of the fixed base 1 and above the conveyor belt 2. Dust hoods 20 are installed at equal intervals on both sides of the inner wall of the baffle frame 4. The air outlets of multiple dust hoods 20 are connected to dust suction pipes 21. The air outlet of the dust suction pipes 21 is connected to a dust collection pipe 22. The air outlet of the dust collection pipe 22 is connected to a guide pipe 23. The air outlet of the guide pipe 23 passes through the fixed base 1 and is connected to a guide pipe 24. The air outlet of the guide pipe 24 is connected to an outlet pipe 25. The air outlet of the outlet pipe 25 is connected to a filter box 16. A sealing cover 1 is sealed to the top of the filter box 16. 601, the air outlet of the filter box 16 is connected to the vacuum fan 17 through the connecting pipe 1602. Positioning blocks 1603 are fixed at equal intervals on both sides of the inner wall of the filter box 16, and filter plates 26 are inserted between the two positioning blocks 1603 on both sides of the inner wall of the filter box 16. Three filter plates 26 are inserted inside the filter box 16. The filter box 16 and the vacuum fan 17 are both installed in the groove opened at the bottom of the inner cavity of the fixed base 1. The surface of the three filter plates 26 is provided with filter screens, and the mesh size of the filter screens decreases sequentially from the air outlet direction of the outlet pipe 25 to the air inlet direction of the connecting pipe 1602.

[0035] Specifically, the shielding frame 4 shields and protects the polishing station, thus blocking the dust generated during polishing to a certain extent and preventing further spread of the dust. The dust suction hood 20, which is designed to continuously generate suction, can also extract the dust generated during the polishing process in a timely manner, further preventing the possibility of dust scattering. Through the connection of the suction pipe 21, dust collection pipe 22, guide pipe one 23, guide pipe two 24 and outlet pipe 25, the dust extracted by the dust suction hood 20 can be introduced into the filter box 16. Since the filter box 16 is equipped with three filter plates 26, and the filter mesh aperture on the three filter plates 26 decreases in size in sequence, the dust particles are filtered from large to small, resulting in a better filtration effect. All three filter plates 26 are inserted into the filter box 16, and can be easily replaced by opening the sealing cover 1601.

[0036] When using this application:

[0037] Start servo motor 5. The power output shaft of servo motor 5 drives the connected I-beam 7 to rotate. It also drives another I-beam 7 to rotate via belt drive. This drives the rotating roller 601 to rotate via drive shaft 6. After the rotating roller 601 rotates, the transmission belt 2 moves and drives the rotating roller 19 to rotate. When the transmission belt 2 moves, the operator can put the mobile phone back cover 27 to be polished into the storage slot 3 at the top of the transmission belt 2. The transmission belt 2 drives the mobile phone back cover 27 to move towards one side of the shielding frame 4 until the mobile phone back cover 27 is transferred to the inside of the shielding frame 4. Then, turn off servo motor 5.

[0038] Servo motor 210 and servo motor 313 are started. Servo motor 210 drives lead screw 11 to rotate, thereby moving slider 9 and adjusting the lateral position of polishing wheel 1401. Servo motor 313 drives lead screw 2 to rotate 1301, thereby moving slider 2 1201 and adjusting the longitudinal position of polishing wheel 1401. Finally, cylinder 14 can be started. The power output shaft of cylinder 14 pushes polishing wheel 1401 close to the mobile phone back cover 27 in the storage slot 3 on the conveyor belt 2. Polishing motor 28 is started. Polishing motor 28 drives polishing wheel 1401 to polish mobile phone back cover 27 in storage slot 3.

[0039] During the polishing process, the dust extraction fan 17 is activated. The dust extraction fan 17 extracts the dust generated during polishing inside the shielding frame 4 through the dust extraction hood 20, and then enters the filter box 16 through the dust extraction pipe 21, dust collection pipe 22, guide pipe one 23, guide pipe two 24 and outlet pipe 25. The dust is then filtered three times by the three filter plates 26 in the filter box 16, filtering dust particles of different sizes in sequence, resulting in better dust filtration. The filtered air enters the dust extraction fan 17 through the connecting pipe 1602 and is then discharged.

[0040] After one mobile phone back cover 27 is polished, the servo motor 5 is restarted to drive the conveyor belt 2 to transport the next mobile phone back cover 27 to be polished into the shielding frame 4. The above action is repeated to polish subsequent mobile phone back covers 27. When the polished mobile phone back cover 27 reaches the leftmost side of the conveyor belt 2, the rotating roller 19 is also rotating, which synchronously drives the two ejector blocks 1901 to rotate. When the ejector block 1901 rotates into the ejector hole 301, it can push the mobile phone back cover 27 out of the storage slot 3 and drop it into the collection frame. In step 15, automatic feeding is achieved. As the polished back cover plate 27 is continuously conveyed, it can work with the alternating rotation of the two ejector blocks 1901 to continuously eject the back cover plate 27 from the storage slot 3 of the conveyor belt 2. After being ejected from the storage slot 3, the back cover plate 27 is transported to the right side of the fixed base 1 by the cyclic transmission of the conveyor belt 2. This allows the staff to continuously place the back cover plate 27 to be polished on the right side of the fixed base 1, enabling continuous polishing operations and higher polishing efficiency for the back cover plate 27.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
