[0073] The tinning mechanism 50 includes a tin furnace 51 and a manipulator 52 for grabbing the speaker 10. A flux tank 53 is provided on the side of the tin furnace 51. The manipulator 52 includes a material taking head 521 and a material taking head driving assembly 522 for driving the material taking head 521 to flip. In this embodiment, the material taking head 521 can flip within an angle of 90°. When working, the material taking head 521 grabs the speaker 10, and then the material taking head driving assembly 522 drives the material taking head 521 to flip, so that the speaker 10 The second welding end of the wire is first extended into the flux in the flux tank 53, and then the material taking head driving component 522 drives the material taking head 521 to flip over, so that the second welding end of the wire leaves the flux tank 53, and then the material taking head driving component 522 drives the material taking head 521 to flip over, so that the second welding end of the wire extends into the tin liquid in the tin furnace 51, and finally the material taking head driving component 522 drives the material taking head 521 to flip over, so that the second welding end of the wire leaves the tin furnace 51 to complete the tinning work.

When working, the stepper motor drives the material conveyor belt 57 to operate so as to send the material tray 58 to the side of the robot 52. The robot 52 puts the tinned speaker 10 into the material tray 58. When the material tray 58 is full of speakers 10, the stepper motor drives the material conveyor belt 57 to operate so as to send the material tray 58 away. At the same time, another material tray 58 will be sent to the side of the robot 52, and then the robot 52 can continue to put the speaker 10 into the material tray 58. By adopting a stepper motor, the robot 52 can fill the material tray 58 with speakers 10 before sending it away. There is no need for manual tray placement, which avoids manual collision damage to the speaker 10 and improves work efficiency.

[0076] The working process of this embodiment is described in detail as follows:

[0077] First, the detection component 22 in the adjustment mechanism 21 detects the direction of the welding position of the speaker 10, and the adjustment component 23 adjusts the direction of the welding position of the speaker 10, so as to ensure that the subsequent welding work will not be welded in the wrong position. Then, the turntable 20 sends the speaker 10 with the adjusted direction to the wire feeding mechanism 30. At this time, the first welding end of the wire needs to be stripped by the stripping and cutting mechanism 70. After the stripping is completed, the wire feeding mechanism 30 sends the first welding end of the wire to the welding position of the speaker 10, and the wire welding mechanism 60 performs welding, and according to the required reserved length of the wire, the wire can be cut by the stripping and cutting mechanism 70. Next, the turntable 20 sends the speaker 10 with the wire welded to the wire twisting mechanism 40, where the wire twisting mechanism 40 twists the wires welded on the speaker 10 together. Afterwards, the turntable 20 sends the speaker 10 with the wires tightened to the tinning mechanism 50. At this time, the material picking head 521 grabs the speaker 10. Driven by the material picking head driving assembly 522, the material picking head 521 flips over so that the second welding end of the wire is successively extended into the flux in the flux tank 53 and the tin liquid in the tin furnace 51. Finally, the robot 52 puts the speaker 10 into the material tray 58.
