Description

Technical Field

[0001] This utility model relates to the field of shell processing and polishing technology, specifically to a smart door lock shell processing and polishing device. Background Technology

[0002] In the manufacturing of smart locks, the polishing of the outer casing is a crucial step that determines the product's appearance quality and user experience. As consumers' demands for the refinement and smoothness of smart lock appearances continue to rise, the shortcomings of traditional polishing devices are becoming increasingly apparent, making it difficult to meet the requirements of high-quality production.

[0003] Uneven polishing results are one of the core issues restricting product quality. Existing polishing devices generally suffer from limited functionality, with most only capable of polishing a single grit size. They cannot flexibly switch polishing tools according to different processing stages of the smart lock casing (such as rough polishing, fine polishing, and polishing). Because smart lock casings often contain complex structures such as flat surfaces, curved surfaces, edges, and grooves, single-function polishing components struggle to adapt to diverse surface shapes. This results in some areas being over-polished, causing scratches and dents, while other areas are under-polished, leaving original imperfections. Ultimately, this leads to inconsistent surface flatness and smoothness, severely affecting product consistency and aesthetics.

[0004] Meanwhile, during the polishing process, a large amount of polishing shavings, dust, and debris inevitably remain on the surface of the outer casing. These attached impurities affect the adhesion of subsequent surface treatment processes such as coating and electroplating, leading to defects such as coating or plating peeling and blistering. However, in traditional devices, polishing and cleaning are often independent steps. After polishing, the outer casing must be manually transferred to cleaning equipment, which not only increases the time cost of process connections but also poses a risk of damage and contamination during the transfer, severely restricting production continuity and improving product qualification rates. Therefore, those skilled in the art provide a smart door lock outer casing processing and polishing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a smart door lock shell processing and polishing device to solve the problems mentioned in the background art.

[0026] 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.

[0027] Please see Figures 1-4 This utility model provides a technical solution:

[0028] A smart door lock shell processing and polishing device, comprising:

[0029] A processing table 1 is provided with a dust collection chamber 13. A support frame 14 is installed inside the dust collection chamber 13. A grid mesh 15 is clamped on the support frame 14. Handles 16 are provided at both ends of the grid mesh 15. A sewage pipe 17 is installed on one side of the dust collection chamber 13. A control valve 18 is installed on the sewage pipe 17. First robotic arms 2 for loading and unloading materials are installed at both ends of the processing table 1. A support frame 3 is provided on the processing table 1. Clamping components are installed on both sides of the support frame 3. A grinding mechanism is installed at one end of the support frame 3, and a cleaning mechanism is installed at the other end of the support frame 3. A controller 4 is installed on the support frame 3.

[0030] Specifically, the clamping assembly includes a first electric slide rail 19, an electric push rod 20, and a clamping plate 21. The first electric slide rail 19 is mounted on the support frame 3, the electric push rod 20 is connected to the first electric slide rail 19, and the output end of the electric push rod 20 is connected to the clamping plate 21.

[0031] The overall operation of the smart door lock shell processing and polishing device begins with the loading stage. The controller 4 drives the first robotic arms 2 at both ends of the processing table 1 to precisely grasp the shell to be processed and place it on the processing table 1. This process is fully automated, reducing manual intervention and laying the foundation for the stability of subsequent processing. Next, the clamping assembly starts to work. The first electric slide rail 19 drives the electric push rod 20 to move to the appropriate position. The electric push rod 20 extends to clamp the shell with the clamping plate 21. This flexible clamping method can adapt to the fixing requirements of shells of different sizes, ensuring that the shell will not shift during polishing and guaranteeing processing accuracy.

[0032] The cleaning mechanism includes a rinsing assembly and a drying assembly. The rinsing assembly includes a water tank 22, a drain pipe 23, a drain cover 24, a water pump 25, and a flow control valve 26. The water tank 22 is mounted on a support frame 3. One end of the drain pipe 23 is connected to the water tank 22, and the other end of the drain pipe 23 passes through the support frame 3 and is connected to the drain cover 24. The water pump 25 and the flow control valve 26 are connected to the drain pipe 23. The drying assembly includes a drying fan 27, a first connecting pipe 28, a second connecting pipe 29, and two electrically controlled valves 3. 0. Exhaust hood 31, exhaust pipe 32 and several exhaust nozzles 33, drying fan 27 is mounted on support frame 3, exhaust pipe 32 is mounted on mounting plate 5, one end of first connecting pipe 28 and second connecting pipe 29 is connected to drying fan 27, and the first connecting pipe 28 and second connecting pipe 29 pass through support frame 3 and are respectively connected to exhaust pipe 32 and exhaust hood 31, several exhaust nozzles 33 are mounted on exhaust pipe 32, and two electrically controlled valves 30 are respectively connected to first connecting pipe 28 and second connecting pipe 29;

[0033] After polishing, the cleaning mechanism takes over. Water pump 25 delivers water from water tank 22 to drain cover 24 via drain pipe 23. Flow control valve 26 precisely controls the drainage volume based on the material of the outer shell (e.g., metal materials require a larger water volume to rinse away debris, while plastic materials require controlled water volume to avoid residue), the size of the polishing area (large-area polishing requires correspondingly increased water volume), and the amount of residual debris after polishing (predicted through pre-polishing parameters or feedback from visual sensors). Controller 4 receives preset outer shell processing parameters or real-time sensor data and sends an electrical signal to flow control valve 26 to adjust its valve opening, thereby achieving precise control of the drainage volume and targeted rinsing of the polished outer shell. Wastewater and some polishing debris fall into dust collection chamber 13 through grille 15 and can be discharged through drain pipe 17 and control valve 18. The snap-fit ​​design of grille 15 and handle 16 facilitate regular removal and cleaning. After rinsing, the rinsing assembly stops working, and the exhaust hood 31 of the drying assembly starts working. Hot air generated by the drying fan 27 is blown out of the exhaust hood 31 through the second connecting pipe 29 to dry the damp shell. The electronically controlled valve 30 controls the hot air volume based on the shell material (metal conducts heat quickly, so the air volume can be reduced; plastic is easily affected by high temperatures, so the air volume and temperature need to be matched), surface humidity (detected in real time by a humidity sensor), and ambient temperature (when the ambient temperature is low, the air volume needs to be increased to improve drying efficiency). The controller 4 controls the electronically controlled valve 30 to send adjustment signals, controlling the hot air flow by changing the valve opening degree, thereby achieving precise air volume control and ensuring drying efficiency. Finally, the clamping assembly releases the shell, and the first robotic arm 2 moves the processed shell to the next process, completing the entire processing flow.

[0034] The grinding mechanism includes an adjustment component, a mounting plate 5, and three grinding components. Each of the three grinding components includes a drive component, a connecting block 6, a pressure sensor 7, a first connecting plate 8, and a second connecting plate 9. Each of the three grinding components also includes a first grinding disc 10, a second grinding disc 11, and a third grinding disc 12. The pressure sensor 7 is installed between the connecting block 6 and the first connecting plate 8, and the first grinding disc 10, the second grinding disc 11, and the third grinding disc 12 are connected to the second connecting plate 9. The first connecting plate 8 and the second connecting plate 9 are connected by screws. The bolt connection and drive assembly include a second robotic arm 34, a mounting frame 35, and a drive motor 36. The second robotic arm 34 is mounted on the mounting plate 5 and connected to the mounting frame 35. The drive motor 36 is mounted inside the mounting frame 35 and its output end is connected to the connecting block 6. The adjustment assembly includes a second electric slide rail 37 and a servo cylinder 38. The second electric slide rail 37 is mounted on the support frame 3, and the servo cylinder 38 is connected to the second electric slide rail 37 and its output end is connected to the mounting plate 5.

[0035] Upon entering the grinding stage, the second electric slide rail 37 of the adjustment component works in conjunction with the servo electric cylinder 38 to move the mounting plate 5 and the three grinding components to the designated grinding position. The controller 4 selects the corresponding grinding component according to the processing requirements, and the second robotic arm 34 flexibly adjusts the posture of the mounting frame 35 to align the grinding disc with the area to be ground. After the drive motor 36 starts, it drives the grinding disc to rotate through the connecting block 6, the first connecting plate 8, and the second connecting plate 9. At the same time, the pressure sensor 7 between the connecting block 6 and the first connecting plate 8 monitors the grinding pressure in real time and feeds it back to the controller 4. The controller 4 adjusts the speed of the drive motor 36, the posture of the second robotic arm 34, etc., to form a closed-loop control, ensuring accurate grinding force and greatly improving the uniformity and effect of grinding. During the grinding process, the exhaust nozzles 33 on the exhaust pipe 32 work synchronously. The airflow generated by the drying fan 27 blows out from the exhaust nozzles 33 through the first connecting pipe 28 and the exhaust pipe 32, blowing the waste generated by grinding onto the grid 15 and then into the dust collection chamber 13.

[0036] In the above embodiments, the controller 4 is electrically connected to the first robotic arm 2, the pressure sensor 7, the control valve 18, the first electric slide rail 19, the electric push rod 20, the water pump 25, the flow control valve 26, the drying fan 27, the electric control valve 30, the second robotic arm 34, the drive motor 36, the second electric slide rail 37, and the servo electric cylinder 38.

[0037] It should be noted that the specific models and specifications of the controller 4, the first robotic arm 2, the pressure sensor 7, the control valve 18, the first electric slide rail 19, the electric push rod 20, the water pump 25, the flow control valve 26, the drying fan 27, the electric control valve 30, the second robotic arm 34, the drive motor 36, the second electric slide rail 37, and the servo electric cylinder 38 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
