The controller adopts existing known and mature technology, which will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connections will not be explained in detail here.

[0028] The principle of this invention The machine rotates clockwise on a turntable, stopping for 1-3 seconds at each station to achieve a cyclical assembly process of lower cover → middle ball → upper cover gluing → welding → discharge. Each component works in a pre-set sequence to ensure efficient and precise automated production.

[0029] Workflow: When the turntable assembly 7 is started, the turntable 24 rotates to the work position of the lower cover feeding assembly 2, and the lower cover robotic arm gripping mechanism 8 grips the lower cover from the lower cover conveying track 11 and places it on the placement seat 26 of the turntable 24. The placement seat 26 with the lower cover on the turntable 24 rotates to the work position of the intermediate ball feeding assembly 3. The central lifting mechanism 13 in the center of the intermediate ball tray 12 lifts the intermediate ball, and the intermediate ball robotic arm gripping mechanism 14 grips the lifted intermediate ball and places it in the lower cover in the placement seat 26. The turntable 24 rotates to place the lower cover and the middle ball on the placement seat 26 to the station of the upper cover feeding and gluing assembly 4. The upper cover robotic arm gripping mechanism 19 grips the upper cover conveyed by the upper cover conveying track 17, places it in the glue coating mechanism 18 for gluing, and then places the glued upper cover on the placement seat 26 of the turntable 24 to complete the gluing assembly of the upper cover and the lower cover. Turntable 24 continues to rotate, transporting the assembled and glued bell to the station of ultrasonic welding assembly 5. The lifting mechanism 21 of ultrasonic welding assembly 5 drives the welding head 20 to descend and contact the surface of the bell. The residual glue is removed and the surface stains are cleaned by ultrasonic energy. As turntable 24 continues to rotate, when the assembled bell is conveyed to the mobile finished product discharge component 6, the finished product robotic arm gripping mechanism 23 grabs the assembled bell and places it on the finished product conveying track 22, and then slides down obliquely to be conveyed to the finished product collection box.

[0030] This invention enables multi-station cyclic assembly through a turntable assembly, and, in conjunction with the circumferential distribution of three feeding components, forms a continuous assembly process. It integrates glue application and ultrasonic welding functions, ensuring uniform glue application at the joint between the upper and lower covers of the bell, eliminating glue leakage and overflow, and guaranteeing excellent sealing of the assembled bell. The bell components are conveyed with high precision, and the assembly process is seamless, significantly improving production efficiency and product quality. It also reduces labor intensity and is suitable for large-scale automated production of bells, efficiently completing the entire bell assembly process.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
