Description

Technical Field

[0001] This invention relates to the field of automated smoke alarm assembly equipment, and in particular to an automated smoke collection box assembly equipment. Background Technology

[0002] Smoke detectors are assembled from PCB boards and corresponding components within the PCBs, as well as parts such as the central clip. The internal smoke collection box has a complex structure, consisting of a shell, a top cover, and numerous internal chips and diodes. Due to the large number of components, the assembly process is complex and requires a lot of precise operations. Each component needs to be assembled in a fixed position, resulting in many assembly steps. In traditional manual assembly, this is time-consuming and labor-intensive, not only inefficient but also prone to errors. Furthermore, it increases the labor intensity and costs, making it unsuitable for large-scale industrial production. Additionally, the assembled product is prone to quality problems, posing certain safety hazards during use. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The problem to be solved by the present invention is to provide an automated smoke collection box assembly device to overcome the shortcomings of the prior art where the smoke collection box of the smoke alarm needs to be manually assembled, resulting in low production efficiency.

[0005] (II) Technical Solution

[0006] To solve the aforementioned technical problem, the present invention provides an automated cigarette box assembly device, including a workbench on which a first turntable and a second turntable are rotatably mounted. Multiple sets of feeding and picking devices are arranged around the workbench. Multiple first positioning seats are arranged in a ring at equal intervals on the first turntable, and multiple second positioning seats are arranged in a ring at equal intervals on the second turntable. The picking devices are used to pick up materials from the feeding devices and assemble workpieces into the first and second positioning seats. A conversion platform is installed between the first and second turntables to transport workpieces from the first positioning seats to the second positioning seats. A winding device is installed on one side of the second turntable to wind an insect-proof net. A feeding platform is located on one side of the winding device to fit the insect-proof net onto the assembled workpiece.

[0007] Furthermore, the winding device includes a second conversion table, a first rotating seat, and a second rotating seat. The first rotating seat and the second rotating seat have the same structure and are both slidably mounted on a lead screw seat. A servo motor is installed inside both the first rotating seat and the second rotating seat. A gripper is connected to the servo motor. The bottom of the second conversion table is equipped with the same gripper. After the three grippers hold the strip-shaped filter screen, the servo motor drives the first rotating seat and the second rotating seat to rotate, winding the filter screen into the insect-proof net. The lead screw seat can drive the first rotating seat and the second rotating seat to slide, so as to adjust the position according to the length of the filter screen.

[0008] Furthermore, a material handling platform is provided on one side of the winding device. The material handling platform includes a positioning frame and a positioning table that is retractably mounted on the positioning frame by a spring. The positioning table is circular. The feeding platform includes a robotic arm movably mounted on the worktable and a cross-shaped gripper fixed to the bottom of the robotic arm. A hollowed-out annular pressure table is installed at the bottom of the robotic arm. The cross-shaped gripper passes through the annular pressure table. When picking up the material, the gripper on the second conversion platform clamps the insect-proof net onto the positioning table. The robotic arm drives the cross-shaped gripper to move above the positioning table and then presses down. The annular pressure table presses down on the positioning table, causing the positioning table to retract. At this time, the cross-shaped gripper is placed inside the insect-proof net. The cylinder can drive the cross-shaped gripper to expand outward synchronously and fix the insect-proof net, which is then removed. The spring can drive the positioning table to reset. After picking up the part, the cross-shaped gripper puts the insect-proof net onto the workpiece. The annular pressure table presses down again to fix the insect-proof net.

[0009] Furthermore, the conversion table includes a guide table, a swing frame, and a material picker. The guide table is equipped with a slide, and the material picker is slidably mounted on the slide. A drive motor is installed on one side of the guide table, passing through the guide table and connected to the swing frame. The swing frame is provided with a waist-shaped groove, and a bearing assembly is movably installed in the waist-shaped groove. The guide table is also provided with an inverted U-shaped groove. One end of the bearing assembly is placed in the U-shaped groove, and the other end of the bearing assembly is connected to the material picker. The drive motor drives the swing frame to swing, and the bearing assembly drives the material picker to move along the U-shaped groove and simultaneously move laterally along the slide, thereby realizing the transport of the workpiece.

[0010] Furthermore, a discharge platform is installed on one side of the second turntable, and a third transfer platform is provided on one side of the discharge platform. The discharge platform includes a conveyor belt, and a sensor is provided at the end of the conveyor belt to sense whether the workpiece is placed in place.

[0011] Furthermore, the feeding device includes a vibrating disc and a track, with a workpiece placed inside the vibrating disc, and both the first positioning seat and the second positioning seat having positioning grooves corresponding to the workpiece.

[0012] Furthermore, the feeding device includes a robotic arm and a suction plate. The robotic arm is rotatably mounted on the worktable, and the suction plate is liftably mounted on the robotic arm for picking up workpieces.

[0013] Furthermore, the workpieces placed in the vibrating disc are a material tray, a top cover, and a diode. A camera detector is provided between the vibrating disc, which holds the material tray and the top cover, and the picking device. The first turntable is used to assemble the diode assembly, and the second turntable is used to assemble the diode assembly with the material tray while closing the top cover. The camera detector is used to detect whether the material tray and the top cover are in the correct position when they are sent out of the vibrating disc. If they do not correspond, the angle needs to be adjusted by rotating the picking device. When the workpiece is a material tray, the suction disc is replaced by a gripper.

[0014] Furthermore, a pressing platform is provided on one side of the vibrating material tray where the material tray and the top cover are placed. The pressing platform can be lifted and installed on the worktable and corresponds to the second positioning seat. The bottom of the pressing platform is provided with a positioning groove. The pressing platform is used to press the material to make the assembly firm.

[0034] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0035] See Figures 1-16 This invention provides an automated cigarette box assembly device, including a workbench on which a first turntable 1 and a second turntable 2 are rotatably mounted. Specifically, the turntable 1 and the second turntable 2 are driven to rotate at a constant speed by a motor located at the bottom between them, and the rotation speed can be adjusted as needed. Multiple feeding and picking devices are arranged around the workbench. The first turntable 1 has multiple first positioning seats 3 arranged in a ring at equal intervals, and the second turntable 2 has multiple second positioning seats 4 arranged in a ring at equal intervals. The feeding devices are used to transport the required workpieces to one side of the first turntable 1 and the second turntable 2, respectively, and the picking devices are used to clamp the workpieces. After being picked up or sucked up, the workpiece is assembled into the first positioning seat 3 and the second positioning seat 4. A conversion table is installed between the first turntable 1 and the second turntable 2. In this embodiment, the first turntable 1 is used to assemble chipsets and diodes, etc., and the second turntable is used to assemble the entire smoke collection box. The conversion table is used to transport the assembled chipset in the first positioning seat 3 to the second positioning seat 4. A winding device is installed on one side of the second turntable 2. The winding device is used to wind the insect-proof net 5. A feeding table is provided on one side of the winding device. The feeding table is used to put the insect-proof net 5 onto the workpiece, that is, onto the outer wall of the smoke collection box, to achieve the insect-proof function.

[0036] See Figure 15In this embodiment, the winding device includes a second conversion table, a first rotating seat 6, and a second rotating seat 7. The first rotating seat 6 and the second rotating seat 7 have the same structure and are both slidably mounted on a lead screw seat 8. A servo motor 9 is installed inside both the first rotating seat 6 and the second rotating seat 7. A gripper 10 is connected to the servo motor 9. The bottom of the second conversion table is equipped with the same gripper 10. After the three grippers 10 clamp the strip-shaped filter screen, the servo motor 9 drives the first rotating seat 6 and the second rotating seat 7 to rotate, winding the filter screen into an insect-proof net 5. The lead screw seat 8 is used to adjust the rotation of the first rotating seat 6 and the second rotating seat 7. The position of the rotating seat 7 can be adjusted according to the required diameter of different insect-proof nets 5. The distance between the first rotating seat 6 and the second rotating seat 7, as well as the distance between the rotating seat 7 and the second conversion table, can be adjusted. The servo motor 9 is used to drive the end gripper 10 to rotate. Since the gripper 10 clamps the filter screen, the filter screen can be positioned by the gripper 10 on the second conversion table. The gripper 10 on the first rotating seat 6 and the second rotating seat 7 rotates the filter screen. In this embodiment, the filter screen can be assembled by plugging in both ends, or it can be wound and then welded. The filter screen needs to be automatically transported by an external conveying device, etc.

[0037] See Figures 13-16 In this embodiment, a material picking platform is provided on one side of the coiling device. The picking platform includes a positioning frame 11 and a positioning table 13 that is telescopically mounted on the positioning frame 11 via a spring 12. The positioning table 13 is circular. The feeding platform includes a robotic arm 14 movably mounted on the workbench and a cross-shaped pneumatic gripper 15 fixed to the bottom of the robotic arm 14. A hollowed-out annular pressure table 16 is mounted on the bottom of the robotic arm 14. The cross-shaped pneumatic gripper 15 passes through the annular pressure table 16. The robotic arm 14 can drive the feeding platform to swing and rotate as a whole, and can also drive the cross-shaped pneumatic gripper 15 and the annular pressure table 16 to rise and fall, preventing insects. After the net 5 is processed, the grippers 10 on the first rotating seat 6 and the second rotating seat 7 are released. The grippers 10 on the second conversion table transport the insect net 5 to the positioning table 13 for engagement. The robotic arm 14 drives the cross gripper 15 to move to the positioning table 13 to engage with the insect net 5. At the same time, the annular pressure table 16 descends and presses down the positioning table 13. The cylinder drives the cross gripper 15 to open and position the insect net 5. Then, the robotic arm 14 drives the entire insect net 5 to be removed. The spring 12 can drive the positioning table 13 to reset. After the material is removed, the robotic arm 14 reassembles the insect net 5 onto the second positioning seat 4.

[0038] See Figure 8 and Figure 9In this embodiment, a discharge platform is also installed on one side of the second turntable 2, and a third conversion platform is provided on one side of the discharge platform. The discharge platform includes a conveyor belt 25, and a sensor 26 is provided at the end of the conveyor belt 25. The sensor 26 is used to sense whether a workpiece is placed on the conveyor belt 25. One end of the conveyor belt 25 can be connected to a storage box, and the finished workpiece is transported to the storage box by the conveyor belt 25. In this embodiment, the conversion platform, the second conversion platform, and the third conversion platform have the same structure. The conversion platform includes a guide table 17, a swing frame 18, and a picking seat 19. A slide table 20 is provided on the guide table 17, and the picking seat 19 is slidably installed on the guide table 17. On the slide table 20, a drive motor 21 is installed on one side of the guide table 17. The drive motor 21 passes through the guide table 17 and is connected to the swing frame 18. The swing frame 18 is provided with a waist-shaped groove 22. A bearing assembly 23 is movably installed in the waist-shaped groove 22. The guide table 17 is also provided with an inverted U-shaped groove 24. One end of the bearing assembly 23 is placed in the U-shaped groove 24, and the other end of the bearing assembly 23 is connected to the material picker 19. When the drive motor 21 operates, it can drive the swing frame 18 to swing. Simultaneously, the bearing assembly 23 drives the material picker 19 to move along the U-shaped groove 24 to realize the transport of the workpiece. At the same time, the material picker 19 slides along the slide table 20.

[0039] See Figure 12In this embodiment, the feeding device includes a vibrating disc 27 and a track 28. The vibrating disc 27 holds a workpiece. Both the first positioning seat 3 and the second positioning seat 4 have positioning slots 29 corresponding to the workpiece, allowing the workpiece to be assembled to be placed into the corresponding positioning slots 29. The feeding device includes a robotic arm 14 and a suction disc 30. The robotic arm 14 is rotatably mounted on a worktable, and the suction disc 30 is liftably mounted on the robotic arm 14. The workpieces placed in the vibrating disc 27 are material trays, top covers, and diodes, among other accessories. A camera detector 31 is provided between the vibrating disc 27 (where the material tray and top cover are placed) and the picking device. Since the material tray or top cover requires a specific angle for installation, the position needs to be detected before the picking device rotates the workpiece for assembly. When the workpiece is a material tray, the suction disc 30 needs to be replaced with a gripper 10 for easier gripping. In this embodiment, a pressure plate is also provided on one side of the vibrating disc 27 (where the material tray and top cover are placed). The material platform 32 and the pressing platform 32 can be lifted and installed on the worktable and correspond to the second positioning seat 4. The bottom of the pressing platform 32 is provided with a positioning groove 33. The vibrating plate 27 on one side of the first turntable 1 is respectively equipped with spring holders, diodes, chips, etc. The picking device assembles them onto the first positioning seat 3, and then the transfer table transports them to the second positioning seat 4. The pressing platform 32 on the back of the transport presses the workpiece assembled on the first positioning seat 3 to achieve positioning. The positioning groove 33 plays a role in avoiding obstacles and achieving precise assembly. After the workpiece is transported as a whole, the picking device at the second turntable 2 assembles the material tray onto the second positioning seat 4 to cooperate with the workpiece transported from the first positioning seat 3. Then the feeding table assembles the insect-proof net 5 around the material tray. During assembly, the annular pressing platform 16 presses down on the insect-proof net 5 to achieve positioning. Finally, the picking device installs the top cover on the material tray, and the pressing platform 32 presses the material again. Finally, the unloading platform transports out the finished workpiece.
