Description

Technical Field

[0001] The utility model relates to the technical field of earphone component processing, in particular to an earphone diaphragm assembly welding device. Background Art

[0002] After the headphone diaphragm is assembled to the headphone diaphragm bracket, it needs to be welded. The current assembly process in the factory is to load the headphone diaphragm and the headphone diaphragm bracket respectively through two feeding lines, and then assemble them manually, put the headphone diaphragm on the headphone diaphragm bracket, and finally operate the welding machine for laser welding.

[0028] The base 1 is formed into a substantially square base 1 structure, a rotating mechanism 2 is installed on the top surface of the base 1, the rotating mechanism 2 is located in the middle of the top surface of the base 1, and a turntable is installed on the upper end of the rotating mechanism 2, and the radius of the turntable is 1 meter to 1.2 meters;

[0029] The turntable comprises a turntable inner ring 3 and a turntable outer ring 4 which are arranged concentrically. The turntable outer ring 4 is formed into a roughly annular structure. The turntable inner ring 3 is formed into a roughly cylindrical structure. The middle part of the turntable inner ring 3 is transmission-connected with the rotating mechanism 2. The rotating mechanism 2 can be a servo motor. The servo motor rotates 3°~4° each time and stops for 5s after rotation. The middle part of the bottom surface of the turntable inner ring 3 is transmission-connected with the top power output end of the servo motor. The specific connection method can be a keyway connection method. A plurality of connecting beams 5 are fixedly installed between the outer circumference of the inner ring 3 of the turntable and the inner circumference of the outer ring 4 of the turntable. The connecting beams 5 are formed into a roughly cylindrical rod structure. The number of the connecting beams 5 can be selected according to the use requirements, for example, 5. The design purpose is only to connect the inner ring 3 and the outer ring of the turntable. The turntable is driven to rotate by the rotating mechanism 2. A limiting groove 6 for accommodating the earphone diaphragm and the earphone diaphragm bracket is provided on the top surface of the turntable. The distance between two adjacent limiting grooves 6 is 6 cm to 8 cm.

[0030] In order to ensure that the earphone diaphragm and the earphone diaphragm bracket can be relatively stably carried by the turntable, the limiting groove 6 includes an earphone diaphragm limiting groove 7, an earphone diaphragm bracket limiting groove 8 and an ejection groove 9. The earphone diaphragm limiting groove 7 is located on the top surface of the turntable, and the earphone diaphragm limiting groove 7 is formed into a roughly cylindrical groove body structure, and its edge can abut against the edge of the earphone diaphragm. The earphone diaphragm bracket limiting groove 8 is located in the middle of the turntable, and the earphone diaphragm bracket limiting groove 8 is formed into a roughly arc-shaped groove structure, and its inner wall is used to connect with the outer peripheral surface of the earphone diaphragm bracket. The ejection groove 9 is located on the bottom of the turntable, and the ejection groove 9 can be formed into a roughly circular groove body structure, which is convenient for people to reach in. The earphone diaphragm limiting groove 7, the earphone diaphragm bracket limiting groove 8 and the ejection groove 9 are mutually connected from top to bottom.

[0031] In order to enable the earphone diaphragm to be automatically loaded, we also add an earphone diaphragm loading tray 10 and an earphone diaphragm operating plate 11. The earphone diaphragm loading tray 10 can be a vibration loading tray. The earphone diaphragm operating plate 11 is formed into a roughly square plate-shaped structure, and its design purpose is only to receive the incoming materials of the earphone diaphragm loading tray 10. The earphone diaphragm loading tray 10 is located beside the earphone diaphragm operating plate 11, and the discharge port of the earphone diaphragm loading tray 10 is located directly above the earphone diaphragm operating plate 11;

[0032] In order to enable the earphone diaphragm bracket to automatically load materials, we also add an earphone diaphragm bracket loading tray 12 and an earphone diaphragm bracket operating panel 13. The earphone diaphragm bracket loading tray 12 can be a vibration loading tray. The earphone diaphragm bracket operating panel 13 is formed into a roughly square plate-shaped structure, and its design purpose is only to receive the incoming materials of the earphone diaphragm bracket loading tray 12. The earphone diaphragm bracket loading tray 12 is located beside the earphone diaphragm bracket operating panel 13, and the discharge port of the earphone diaphragm bracket loading tray 12 is located directly above the earphone diaphragm bracket operating panel 13;

[0033] In order to prevent the earphone diaphragm and the earphone diaphragm support from being separated from the earphone diaphragm operating plate 11 and the earphone diaphragm support operating plate 13 after loading, a fence 14 is fixedly provided on the top edge of the earphone diaphragm operating plate 11 and the earphone diaphragm support operating plate 13. The fence 14 is formed into a roughly square plate-shaped structure, which is vertically fixed on the top edge of the earphone diaphragm operating plate 11 and the earphone diaphragm support operating plate 13, so as to block the earphone diaphragm and the earphone diaphragm support and prevent them from being separated from the top surface of the earphone diaphragm operating plate 11 and the earphone diaphragm support operating plate 13;

[0034] A welding machine 15, which may be a laser welding machine 15, is located above the upper limit slot 6 of the turntable to weld the earphone diaphragm in the limit slot 6. The welding machine 15 has a welding time of 2 seconds per welding.

[0035] In order to avoid the edge temperature of the headphone diaphragm after welding being too high, we also add a cooling component, which is located above the upper limit groove 6 of the turntable, so as to cool the headphone diaphragm support of the headphone diaphragm machine after welding. The cooling component includes a cold box 16, a connecting pipe 17 and a cooling pipe 18;

[0036] In order to enable the compressed gas in the factory to be used for cooling operations, a quick connector 19 is installed on the top surface of the cold box 16. The cold box 16 is formed into a box-shaped structure with a cavity inside. One end of the connecting pipe 17 is fixed on the top surface of the cold box 16, and the other end is connected to the cooling pipe 18.

The cooling pipe 18 is formed into a roughly arc-shaped tubular structure, and a plurality of air holes are arranged on its bottom surface. The gas entering the cold box 16 through the quick connector 19 is discharged through the connecting pipe 17 and the cooling pipe 18, and the earphone diaphragm and the earphone diaphragm bracket welded in the limit groove 6 below are air-cooled;

[0037] When the welded earphone diaphragm and earphone diaphragm bracket need to be cooled, the external air supply pipe can be connected to the quick connector 19 of the cold box 16, that is, the earphone diaphragm and the earphone diaphragm bracket can be air-cooled by the cooling assembly to avoid burns when manually removing the earphone diaphragm or the earphone diaphragm bracket;

[0038] A finished product conveying platform 20, which is located beside the turntable, is used to convey the cooled earphone diaphragm and earphone diaphragm bracket, and the finished product conveying platform 20 can be a belt conveyor;

[0039] The headphone diaphragm loading tray 10 and the headphone diaphragm operating panel 11, the headphone diaphragm bracket loading tray 12 and the headphone diaphragm bracket operating panel 13, the welding machine 15, the cooling assembly and the finished product conveying platform 20 are sequentially arranged around the turntable in a clockwise or counterclockwise direction.

[0040] When the headphone diaphragm assembly welding device is used;

[0041] First, start the rotating mechanism 2, the earphone diaphragm loading tray 10, the earphone diaphragm bracket loading tray 12, the welding machine 15 and the finished product conveying platform 20 through an external power supply, and then connect the compression pipeline in the factory area to the quick connector 19 on the cold box 16, and set the rotating mechanism 2 to intermittent operation, and its power output end rotates 3.4° each time, and the interval between two adjacent rotations is 5 seconds. The purpose is to facilitate the staff to place the earphone diaphragm and the earphone diaphragm bracket on the earphone diaphragm operating panel 11 and the earphone diaphragm bracket operating panel 13 in the limit groove 6, and set the welding time of the welding machine 15 to 2 seconds, and the time interval between two adjacent weldings can be set to the actual rotation time of the turntable plus 7 seconds each time; after the welding operation, the cooling pipe 18 is used to air-cool the welded earphone diaphragm and the earphone diaphragm bracket below it. After air-cooling, the earphone diaphragm and the earphone diaphragm bracket in the limit groove 6 can be manually taken out and placed on the finished product conveying platform 20;

[0042] Economic benefits: Each production line only requires 3 workers and can handle 375 welds per hour, which greatly improves production efficiency, increases capacity, and simplifies the workload of staff.
