Description

Technical Field

[0001] This invention relates to the field of headphone manufacturing equipment, and more particularly to a welding apparatus for headphone processing. Background Technology

[0002] In headphone production, circuit boards and wires need to be soldered together. Existing soldering devices, such as the headphone connector soldering device disclosed in patent application number CN201620259067.1, include a base with a column on the base. The column is connected to a horizontal guide rod via a vertical slider, and the horizontal guide rod is connected to a soldering device via the horizontal slider. A carrier is provided below the soldering device, which includes a soldering iron and a solder wire feeder next to it. In use, the headphone connector is placed in the placement position, and the wires to be soldered are placed into the corresponding Y-shaped wire grooves. A soldering baffle is flipped to press and fix the wires. At this time, the carrier is pushed under the soldering device to align the soldering iron with the solder joints, and the soldering iron moves down to solder the headphone. However, this type of soldering device requires placing the headphone connector, then placing the wires, and then soldering with the soldering iron. During soldering, it is necessary to wait for the solder wire to be fed, and after soldering, the soldered product is removed and then placed again before soldering can be performed again, resulting in low soldering efficiency.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a welding apparatus for earphone processing.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a welding device for earphone processing, comprising a frame, a rotary motor fixed on the frame, a turntable fixed to the output end of the rotary motor, and fixed seats evenly fixed on the turntable. A transverse lead screw is also provided on the frame, driven to rotate by a transverse motor. A slide table threadedly connected to the transverse lead screw is also provided on the transverse lead screw, and a push rod is provided on one side of the slide table. A push block is fixed to the end of the push rod, which is driven to move by a longitudinal motor. A material-picking cylinder is also fixed on the frame. A material-picking motor is fixed to the end of the piston rod of the material-picking cylinder. A material-picking plate is fixed to the end of the rotating shaft of the material-picking motor. Material-picking rods are symmetrically fixed at both ends of the material-picking plate. A suction cup connected to a vacuum pump is fixed to the bottom of the material-picking rod. A top plate is also fixed on the frame above the turntable. A soldering cylinder is fixed on the top plate. A mounting block is fixed to the end of the piston rod of the soldering cylinder. A solder paste tube is fixed on the mounting block. A soldering cylinder is also fixed on the top plate. The welding gun of an ultrasonic welding machine is fixed to the end of the piston rod of the soldering cylinder.The products to be welded are evenly placed in the troughs of the material tray, and the tray is placed on the slide table. The tray is then positioned using fixing blocks. After placement, the horizontal motor drives the horizontal lead screw to rotate. As the lead screw rotates, the slide table moves, and the first trough on the tray reaches its designated position. The picking cylinder is activated, its piston rod shortens, the picking motor descends, and the picking plate descends. The suction cup at the bottom of the picking rod picks up the product. The picking cylinder is then activated again, its piston rod extends, and the picking plate rises. The product rises with the picking plate, and the picking motor drives the picking plate to rotate. The device rotates 180 degrees and pushes the product in the trough to move. The next product in the trough reaches directly under another suction cup, and the rotary motor drives the turntable to rotate. One of the fixed seats on the turntable reaches directly under the suction cup, and the picking cylinder is activated again. The piston rod on the picking cylinder shortens, and the suction cup lowers the product and places it in the fixed slot of the fixed seat. The other suction cup picks up the product again, the picking cylinder is activated, the piston rod on the picking cylinder extends, and the picking rod rises. This cycle repeats, and the rotary motor drives the turntable to rotate a certain angle, placing the product on the fixed seat. Once the mounting bracket reaches the designated position, the worker places the wire on it. After the wire is secured, the turntable continues to rotate. When the mounting bracket reaches below the solder paste tube, the soldering cylinder is activated, extending the piston rod and lowering the solder paste tube. The top of the solder paste tube is connected to an air pump via an air pipe, which blows air into the tube. Some solder paste is discharged from the soldering tube via a soldering nozzle. After the nozzle contacts the product, solder paste is applied to the contact point between the product and the wire. The soldering cylinder is then activated again, retracting the piston rod and raising the solder paste tube. The turntable continues to rotate, and the tinned mounting bracket reaches directly below the soldering gun. When the solder cylinder is activated, the piston rod on the solder cylinder extends, the soldering gun descends, and after the soldering gun reaches above the solder paste, the solder paste temperature rises. After the solder paste solders the wire to the product, the soldering gun rises, the turntable continues to rotate, and the next product with solder paste applied arrives at the soldering gun position. The soldered product is then removed, and the process is repeated. This device can place products one by one on the fixed base for soldering operations. Moreover, during soldering, it is only necessary to wait for the next product to arrive at the soldering gun position before soldering can begin, eliminating the need to wait sequentially for placing products, fixing wires, and feeding solder wire, greatly improving the product soldering efficiency.

[0007] Preferably, a wire groove is fixed on the fixing base, a fixing groove is provided on the fixing base at the end of the wire groove, and a wire take-up groove is also provided on the fixing base at the fixing groove position.

[0008] Preferably, the frame is further provided with a transverse slide bar, which passes through the slide table and is slidably connected to the slide table.

[0009] Preferably, the frame is further provided with a longitudinal lead screw and a longitudinal slide bar. The longitudinal lead screw is driven to rotate by a longitudinal motor. A slide plate is provided on the longitudinal lead screw and is threadedly connected to it. The longitudinal slide bar passes through the slide plate and is slidably connected to it. When the longitudinal lead screw is driven to rotate by the longitudinal motor, the slide plate moves, the push rod moves, and the push block pushes the product to move within the material trough, allowing each product to be moved sequentially to directly below the suction cup.

[0010] Preferably, a feeding cylinder is also fixed on the top plate. A positioning plate is fixed to the end of the piston rod of the feeding cylinder. A lifting cylinder is fixed to the positioning plate. A positioning block is fixed to the end of the piston rod of the lifting cylinder. A finger cylinder is fixed to the bottom of the positioning block. A cylinder finger is fixed to the output end of the finger cylinder. After the welded product reaches below the finger cylinder, the lifting cylinder is activated, the piston rod of the lifting cylinder extends, the finger cylinder descends, and the two cylinder fingers of the finger cylinder reach the wire-taking slots on both sides of the wire. The finger cylinder is activated, the two cylinder fingers of the finger cylinder close together, and the wire is grasped by the cylinder fingers. Then, the lifting cylinder is activated, the piston rod of the lifting cylinder shortens, and the wire is separated from the fixed seat after being grasped by the finger cylinder. The feeding cylinder is activated, the piston rod of the feeding cylinder shortens, and the welded product is moved to the designated position by the finger cylinder and collected. This process is repeated.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device can place products one by one on the fixed base for soldering. During soldering, it only needs to wait for the next product to arrive at the soldering gun position before soldering can begin. There is no need to wait for products to be placed, wires to be fixed, and solder wire to be fed in sequence, which greatly improves the soldering efficiency of products. Attached Figure Description

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 2As shown, this embodiment discloses a welding device for earphone processing, comprising a frame 1, a rotary motor 3 fixed on the frame 1, a turntable 2 fixed at the output end of the rotary motor 3, a plurality of fixed seats 4 evenly fixed on the turntable 2, a transverse lead screw 8 also provided on the frame 1, the transverse lead screw 8 being driven to rotate by a transverse motor 11, a slide table 10 threadedly connected to the transverse lead screw 8 also provided on the transverse lead screw 8, a push rod 19 also provided on one side of the slide table 10, a push block 20 fixed at the end of the push rod 19, the push rod 19 being driven to move by a longitudinal motor 17, and a material picking cylinder 21 fixed on the frame 1 for picking up materials. A material-picking motor 22 is fixed to the end of the piston rod of cylinder 21. A material-picking plate 23 is fixed to the end of the rotating shaft of the material-picking motor 22. Material-picking rods 24 are symmetrically fixed at both ends of the material-picking plate 23. A suction cup connected to a vacuum pump is fixed to the bottom of the material-picking rods 24. A top plate 25 is also fixed on the frame 1 above the turntable 2. A soldering cylinder 26 is fixed on the top plate 25. An mounting block 27 is fixed to the end of the piston rod of the soldering cylinder 26. A solder paste tube 28 is fixed on the mounting block 27. A soldering cylinder 29 is also fixed on the top plate 25. The welding gun 30 of an ultrasonic welding machine is fixed to the end of the piston rod of the soldering cylinder 29.The products to be welded are evenly placed in the material slots 14 of the material tray 13, and the material tray 13 is placed on the slide table 10. The material tray 13 is limited by the fixing block 12. After the material tray 13 is placed, the horizontal motor 11 drives the horizontal lead screw 8 to rotate. When the horizontal lead screw 8 rotates, the slide table 10 moves, and the first material slot 14 on the material tray 13 reaches the designated position. The picking cylinder 21 is activated, the piston rod on the picking cylinder 21 shortens, the picking motor 22 descends, the picking plate 23 descends, and the suction cup at the bottom of the picking rod 24 picks up the product. Then the picking cylinder 21 is activated again, the piston rod on the picking cylinder 21 extends, the picking plate 23 rises, and the product moves with the picking plate 23. As the suction cup rises, the picking motor 22 drives the picking plate 23 to rotate 180 degrees, and pushes the product in the trough 14 to move via the push block 20. The next product in the trough 14 reaches directly below another suction cup, and the rotary motor 3 drives the turntable 2 to rotate. One of the fixed seats 4 on the turntable 2 reaches directly below the suction cup, and the picking cylinder 21 is activated again. The piston rod on the picking cylinder 21 shortens, and the suction cup pulls the product down and places the product in the fixed slot 5 of the fixed seat 4. The other suction cup picks up the product again, the picking cylinder 21 is activated, the piston rod on the picking cylinder 21 extends, and the picking rod 24 rises. The cycle continues, and the rotary motor 3 drives the turntable 2 to rotate. After rotating a certain angle, the mounting base 4, on which the product is placed, reaches the designated position. The worker places the wire on the mounting base 4. After the wire is fixed, the turntable 2 continues to rotate. When the mounting base 4 reaches below the solder paste tube 28, the soldering cylinder 26 is activated. The piston rod of the soldering cylinder 26 extends, and the solder paste tube 28 descends. The top of the solder paste tube 28 is connected to the air pump through an air pipe. The air pump blows air into the solder paste tube 28, and some solder paste is discharged from the soldering tube on the solder paste tube 28. After the soldering tube contacts the product, the solder paste is applied to the contact position between the product and the wire. The soldering cylinder 26 is activated again, the piston rod of the soldering cylinder 26 shortens, and the solder paste tube 28 rises. The turntable 2 continues to rotate, and the mounting base is now soldered. When the soldering gun 30 is directly below the soldering cylinder 29, the piston rod on the soldering cylinder 29 extends, and the soldering gun 30 descends. After the soldering gun 30 reaches above the solder paste, the temperature of the solder paste rises, and the solder paste solders the wire to the product. Then, the soldering gun 30 rises, and the turntable 2 continues to rotate. The next product with solder paste applied arrives at the position of the soldering gun 30. The soldered product is then removed, and the process is repeated. This device can place products one by one on the fixed base 4 for soldering. Moreover, during soldering, it is only necessary to wait for the next product to arrive at the position of the soldering gun 30 before soldering can begin. There is no need to wait for products to be placed, wires to be fixed, and solder wires to be fed sequentially, which greatly improves the soldering efficiency of the products.

[0020] The fixing base 4 is fixed with a wire groove 6, and a fixing groove 5 is provided on the fixing base 4 at the end of the wire groove 6. A wire take-up groove 7 is also provided on the fixing base 4 at the position of the fixing groove 5.

[0021] The frame 1 is also equipped with a transverse slide bar 9, which passes through the slide table 10 and is slidably connected to the slide table 10.

[0022] The frame 1 is also equipped with a longitudinal lead screw 15 and a longitudinal slide bar 16. The longitudinal lead screw 15 is driven to rotate by a longitudinal motor 17. A slide plate 18 is threadedly connected to the longitudinal lead screw 15. The longitudinal slide bar 16 passes through the slide plate 18 and is slidably connected to it. When the longitudinal lead screw 15 is driven to rotate by the longitudinal motor 17, the slide plate 18 moves, the push rod 19 moves, and the push block 20 pushes the product to move within the material trough 14, allowing each product to be moved sequentially to the area directly below the suction cup.

[0023] Example 2:

[0024] This embodiment discloses a welding device for earphone processing. Based on the structure and principle of embodiment 1, the top plate 25 of this embodiment is also fixed with a feeding cylinder 31. The piston rod end of the feeding cylinder 31 is fixed with a positioning plate 32. The positioning plate 32 is fixed with a lifting cylinder 33. The piston rod end of the lifting cylinder 33 is fixed with a positioning block 34. The bottom of the positioning block 34 is fixed with a finger cylinder 35. The output end of the finger cylinder 35 is fixed with a cylinder finger 36. After the welded product reaches below the finger cylinder 35, the lifting cylinder 33 is activated, the piston rod on the lifting cylinder 33 extends, the finger cylinder 35 descends, and the two cylinder fingers 36 of the finger cylinder 35 reach the wire-collecting slots 7 on both sides of the wire. The finger cylinder 35 is activated again, and the two cylinder fingers 36 on the finger cylinder 35 close together.
