[0002] Microphone, also known as microphone, microphone or microphone, is an important element for converting sound signals into electrical signals. According to the working principle, the microphone is mainly divided into moving coil type, condenser type, electret type and silicon microphone. The microphone has high sensitivity, wide frequency response and other characteristics, and is widely used in recording, live broadcast, performance, conference and other occasions. There are many kinds, and the selection needs to be determined according to the specific needs and use environment to achieve the best recording effect.

[0003] In the production process of earphone, a key process is to weld the copper wire of earphone on the microphone. This process usually needs workers to operate very carefully and patiently. First, the worker will place the microphone on the desktop to ensure that its position is fixed and easy to operate. Next, the worker needs to hold the electric iron with one hand and the soldering tin with the other hand, carefully welding the copper wire on the microphone. However, this traditional welding method has some problems. Since the worker needs to operate the electric iron and the soldering tin at the same time during the welding process, it not only makes the welding efficiency relatively low, but also makes the worker feel very tired after a long time of repeated operation. In addition, this manual welding method is also prone to unstable welding quality, affecting the quality of the final product.

DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] As shown in Figure 2 and Figure 3As shown, the welding mechanism 6 includes a motor-driven push rod 601 fixedly installed in the equipment base 2, the upper end of the motor-driven push rod 601 is fixedly installed with a lifting frame 605, the distal end of the lifting frame 605 is fixedly installed with a welding pressure head 607, the welding pressure head 607 is fixedly installed with a heater 606, the side wall of the lifting frame 605 is fixedly installed with a drive rack 608, the drive rack 608 is rotatably installed with a drive gear 602 on one side, the drive gear 602 is fixedly installed with a drive shaft 603, the drive shaft 603 is provided with an electromagnetic clutch 604, the equipment base 2 is provided with a retainer, and the drive shaft 603 is rotatably installed in the equipment base 2 through the retainer.

[0023] Specifically, the heater 606 is used to heat the welding pressure head 607, and the heated welding pressure head 607 can drive the motor-driven push rod 601 to retract. The retraction action of the motor-driven push rod 601 will cause the lifting frame 605 to move downward, thereby causing the welding pressure head 607 to move downward. During the downward movement of the welding pressure head 607, it first contacts the solder strip 4, causing the front end of the solder strip 4 to melt. The melted solder then drips onto the microphone body 3. With the further downward movement of the welding pressure head 607, the copper wire body 5 is pressed onto the microphone body 3. After the copper wire body 5 contacts the microphone body 3, the extension of the motor-driven push rod 601 is controlled to realize the separation of the welding pressure head 607 from the solder joint. After the welding pressure head 607 separates from the solder joint, the tin water cools and solidifies, thereby realizing the automatic welding of the copper wire body 5 and the microphone body 3.

[0024] As shown in Figure 2 and Figure 4 The feeding mechanism 7 includes a positioning seat 702 fixedly installed on the equipment base 2, the positioning seat 702 is rotatably installed with movable shafts 704 at both side edges, the upper end of the movable shaft 704 is fixedly installed with feeding rollers 701, the feeding rollers 701 are provided with a solder strip 4 therebetween, the lower end of the movable shaft 704 is provided with a transmission shaft 705, the movable shaft 704 is fixedly installed with synchronous gears 703 at the middle position, the synchronous gears 703 are meshed together, the movable shaft 704, the transmission shaft 705 and the drive shaft 603 are all provided with helical gears 706, the helical gears 706 are meshed together, the positioning seat 702 is provided with bearings, and the movable shaft 704 is movably installed on the positioning seat 702 through the bearings.

[0025] Specifically, during the extension of the electric push rod 601, the electromagnetic clutch 604 is in the engaged state. At the same time, the extension action of the electric push rod 601 drives the lifting frame 605 to move upward. The upward movement of the lifting frame 605 will cause the driving rack 608 to move upward synchronously, and the upward movement of the driving rack 608 will cause the rotation of the driving gear 602. The rotation of the driving gear 602 will drive the rotation of the driving shaft 603. In addition, the rotation of the driving gear 602 will also drive the rotation of the transmission shaft 705, and the rotation of the transmission shaft 705 will cause the rotation of the movable shaft 704. Under the cooperation of the synchronous gear 703, the feeding roller 701 will realize synchronous rotation, thereby pushing the solder bar 4 to move forward by a small distance, realizing the automatic feeding function and effectively reducing the labor intensity of workers.

[0026] Working principle: the conveying seat 1 is slidably installed on the equipment base 2 through the conveying chain, and the microphone body 3 can be conveyed to the lower side of the welding pressure head 607. After the microphone body 3 is conveyed to the lower side of the welding pressure head 607, the welding pressure head 607 can be heated by the heater 606. After the welding pressure head 607 is heated, the electric push rod 601 can be retracted, and after the electric push rod 601 is retracted, it will drive the lifting frame 605 to move downward, and when the lifting frame 605 moves downward, it will drive the welding pressure head 607 to move downward. The downward moving welding pressure head 607 will first contact the solder bar 4, causing the front end of the solder bar 4 to melt. The melted tin water will drop onto the microphone body 3. The welding pressure head 607 continues to move downward and can press the copper wire body 5 on the microphone body 3. After the copper wire body 5 is pressed on the microphone body 3, the electric push rod 601 can be controlled to extend, so that the welding pressure head 607 is separated from the welding point. After the welding pressure head 607 is separated from the welding point, the tin water will cool and solidify, thereby automatically welding the copper wire body 5 on the microphone body 3. When the electric push rod 601 extends, the electromagnetic clutch 604 is controlled to be combined, and when the electric push rod 601 extends, it will drive the lifting frame 605 to move upward. When the lifting frame 605 moves upward, it will drive the driving rack 608 to move upward. When the driving rack 608 moves upward, it will drive the driving gear 602 to rotate. After the driving gear 602 rotates, it will drive the driving shaft 603 to rotate. After the driving gear 602 rotates, it will drive the transmission shaft 705 to rotate. After the transmission shaft 705 rotates, it will drive the movable shaft 704 to rotate. Under the action of the synchronous gear 703, the feeding roller 701 will rotate synchronously, thereby driving the solder bar 4 to move forward by a small distance, replacing the worker to automatically feed and reducing the labor intensity of the worker.
