[0020] As Figure 5 shown in the figure, the clamping component includes clamping plates 34, compression springs 35, and electromagnets 36; the two feeding pipes 32 are commonly slidably connected to the clamping plate 34; a compression spring 35 is fixedly connected between the clamping plate 34 and each of the two feeding pipes 32; both of the two clamping plates 34 are made of iron material; an electromagnet 36 capable of generating electromagnetic suction on the iron material clamping plate 34 is installed on each of the two feeding pipes 32; a rubber layer is provided on the lower surface of the clamping plate 34, and the clamping plate 34 can not only increase the frictional resistance generated when clamping the wire 5 through the rubber layer, but also prevent the wire 5 from being clamped and damaged.

[0021] For the orientation descriptions in this article, Figure 1 with the paper surface of the Figure 1 viewpoint facing outwards as the front, and with the paper surface of the

[0022] viewpoint facing inwards as the rear. The usage steps of an automatic sorting speaker accessory processing and welding machine of the present invention are as follows. First, the first group of externally connected manipulators successively place several speaker bodies 4 into the feeding frame 114 in an upright state with two electrode plates facing the positioning rod 113. As Figure 2 shown, the feeding frame 114 is aligned with the vertical pushing plate 112. The speaker bodies 4 sequentially enter the vertical conveyor 11 downward along the feeding frame 114 and are supported by the vertical pushing plate 112. During this process, the positioning rod 113 is located between the two electrode plates of the speaker body 4. At this time, the speaker body 4 is limited and guided by the positioning rod 113 and the feeding frame 114 and will not tip over in any direction. The vertical conveyor belt 111 drives the speaker body 4 to move downward through the vertical pushing plate 112 until the end of the vertical conveyor 11 and then pauses, keeping the speaker body 4 in contact with the bottom end of the positioning rod 113. At the same time, because the maximum width of the positioning rod 113 is equal to the distance between the two electrode plates of the speaker body 4, the two electrode plates of the speaker body 4 are guided by the wedge-shaped rod-like structure of the positioning rod 113 that expands downward to complete the angle adjustment. As Figure 1 and Figure 2 shown, the two electrode plates of the speaker body 4 are at the same horizontal height on both sides of the positioning rod 113, completing the automatic sorting process of the two electrode plates of the speaker body 4.

[0023] Meanwhile, the second group of externally connected manipulators respectively place two wires 5 downward into the two roller conveyors 24. The two roller conveyors 24 respectively convey the two wires 5 downward into the feeding channel 3201 of a feeding pipe 32 until the lower end of the wire 5 tilts leftward along the arc structure of the feeding pipe 32. Subsequently, the electric drive rotating rod 3 drives the two feeding pipes 32 on the fixed block 31 to rotate clockwise upward by ninety degrees in the front view angle. As Figure 5 shown, the feeding pipe 32 drives the wires 5 inside to be suspended from the upright state to the horizontal state. At this time, the left ends of the two wires 5 in the two feeding pipes 32 are respectively aligned with the electrode plates of the first speaker body 4 counted from the bottom up of the vertical conveyor 11.

[0024] After that, the electric push rod 22 pushes the sliding frame 21 to drive the soldering head 2 to move leftward. When the soldering head 2 presses the wire 5 tightly against the electrode plate of the speaker body 4 to the left, the externally connected soldering equipment solders the wire 5 to the electrode plate of the speaker body 4 through the soldering head 2, completing the automatic soldering process of the wire 5 and the electrode plate of the speaker body 4.

[0025] After that, the electric push rod 22 pulls the sliding frame 21 to drive the soldering iron head 2 to move to the right and reset away from the wire 5. At the same time, the electromagnet 36 generates an electromagnetic suction force on the clamping plate 34 to pull it downward. The clamping plate 34 drives the compression spring 35 to compress downward. The clamping plate 34 cooperates with the two feeding pipes 32 to apply a clamping force to the two wires 5 respectively but does not completely clamp them. Then, the electric drive rotating rod 3 drives the two feeding pipes 32 on the fixed block 31 to rotate counterclockwise downward and reset from the front view angle. At this time, because the speaker body 4 is limited by the vertical conveyor 11, the vertical push plate 112 and the positioning rod 113, it cannot move. The clamping plate 34 cooperating with the feeding pipe 32 to apply a clamping force to the wire 5 will also generate obvious moving resistance. During this process, if the wire 5 can be smoothly pulled out from the feeding channel 3201 of the feeding pipe 32, it means that the wire 5 has been firmly welded to the speaker body 4. If the wire 5 fails to be smoothly pulled out from the feeding channel 3201 of the feeding pipe 32 but is directly separated from the speaker body 4, it means that the wire 5 has not been firmly welded to the speaker body 4; the feeding channel 3201 is in a smooth state, which can reduce the friction between the wire 5 and the inner wall of the feeding channel 3201 during the feeding process of the wire 5, and avoid the wire 5 bending due to friction inside the feeding channel 3201, resulting in the inability to be normally sent out from the outlet of the feeding channel 3201; the feeding channel 3201 is set as a funnel-shaped structure that contracts towards the outlet end, which can limit the moving direction of the wire 5, so that after the end of the wire 5 exits from the outlet, it aligns with the corresponding pole piece.

[0026] Finally, the vertical conveyor belt 111 and the vertical push plate 112 of the vertical conveyor 11 convey the speaker body 4 downward, allowing the speaker body 4 to fall downward and transfer to the horizontal conveyor belt 121 of the horizontal conveyor 12. Then, the horizontal conveyor belt 121 drives the speaker body 4 to move leftward through the horizontal push plate 122. When the horizontal conveyor belt 121 of the horizontal conveyor 12 drives the speaker body 4 to move past the image recognition sensor 123, the image recognition sensor 123 performs image recognition on whether there are two wires 5 on the speaker body 4, so as to judge whether the two wires 5 are both firmly welded to the corresponding electrode plates of the speaker body 4, and complete the automatic detection and processing of the welding firmness of the wires 5 on the speaker body 4.

[0027] After the detection, the wire 5 remaining in the feeding channel 3201 due to insufficient welding firmness can fall out of the feeding channel 3201 naturally after the electromagnet 36 is powered off and the clamping is released, without interfering with the placement of new wires 5.

[0028] Embodiment 2: On the basis of Embodiment 1, as Figures 1-6 shown, as Figure 4 and Figure 6As shown, each of the two feeding pipes 32 is provided with a gas delivery channel 3202, and the outlet of the gas delivery channel 3202 is located in the arc structure area of ​​the feeding pipe 32; two adapter tubes 25 corresponding to the gas delivery channels 3202 of the feeding pipe 32 are fixedly connected to the fixed plate 23; the two adapter tubes 25 are connected to the external airflow conveying equipment together.

[0029] When the electric push rod 22 pushes the sliding frame 21 to drive the soldering head 2 to move to the left, the external soldering equipment solders the wire 5 to the electrode sheet of the speaker body 4 through the soldering head 2, and completes the automatic welding process of the wire 5 and the electrode sheet of the speaker body 4. At the same time, the sliding frame 21 drives the two adapter tubes 25 on the fixed plate 23 to be inserted into the air delivery channels 3202 of the two feeding tubes 32 respectively, and the external air flow conveying equipment continuously blows air into the air delivery channels 3202 of the feeding tubes 32 through the adapter tubes 25. The air flow is blown to the left along the air delivery channel 3202 of the feeding tube 32 to the welding part between the speaker body 4 and the wire 5, and the welding part between the speaker body 4 and the wire 5 is cooled, the cooling and forming speed of the welding part between the speaker body 4 and the wire 5 is accelerated, and the automatic cooling process of the welding part between the speaker body 4 and the wire 5 is completed, thereby meeting the need for welding firmness test immediately after welding is completed.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
