Description

Technical Field

[0001] This utility model relates to the field of electronic component processing equipment, and in particular to a quantitative feeding device for soldering multilayer common mode inductors. Background Technology

[0002] Multilayer common-mode inductors are common-mode interference suppression devices designed with ferrite or other materials as magnetic cores and a multilayer structure. They achieve the function of suppressing common-mode signals through specific structures and materials, playing a key role in electronic circuits. In the traditional common-mode inductor soldering process, it is difficult to accurately control the amount of solder added each time when adding solder manually. Too much solder will lead to solder waste, excessively large solder joints affecting the appearance and performance of the product, and may even cause short circuits; too little solder will result in incomplete solder joints, weak soldering, and affect the electrical connection and reliability of the product. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology that requires manual addition of solder liquid and is not precise enough, the technical problem of this utility model is to provide a quantitative feeding device for soldering of multilayer common mode inductors that can accurately control the amount of solder.

[0004] A quantitative feeding device for soldering multilayer common-mode inductors includes a worktable. A placement rack is mounted on the top front side of the worktable, and the placement rack has multiple placement slots, each holding a common-mode inductor. A flux rack is mounted on the top front side of the worktable, located behind the placement rack. A soldering furnace is mounted on the top center side of the worktable, located behind the flux rack. A conveyor belt is mounted on the rear side of the worktable, and a guide plate is mounted on the right side of the conveyor belt. Support frames are symmetrically fixedly connected to the top of the worktable. A motor is fixedly connected to the rear side of the left support frame. Lead screws are rotatably connected to the top of each support frame. The output shaft of the motor is fixedly connected to the lead screw on the left side. A pulley assembly is provided between the two lead screws, located behind the two support frames. The system uses a pulley system to make two lead screws rotate synchronously. Each support frame has a sliding block slidably connected to it, and the sliding block is threadedly connected to the lead screw. When the lead screw rotates, the sliding block can move up and down along the support frame under the action of the threaded transmission. Three sets of electric push rods are fixedly connected to the bottom of each sliding block. Multiple pneumatic grippers are fixedly connected to the telescopic rods of each electric push rod for gripping and moving common-mode inductors. A weighing sensor is installed at the bottom of the soldering furnace to monitor the amount of solder in the furnace in real time for precise control of solder addition. A solder storage tank is placed on the right side of the workbench, and one end of a conveying pipe is connected to the storage tank. The other end of the conveying pipe is connected to the inlet of the soldering furnace. The controller is electrically connected to the motor, electric push rods, and pneumatic grippers, enabling coordinated operation of all components.

[0005] Further explanation: The system also includes a drying chamber. A drying chamber is fixedly connected to the top rear side of the workbench. The drying chamber is located behind the soldering furnace and in front of the conveyor belt. A temperature sensor is installed on the right side of the drying chamber. A hot air blower is fixedly connected to the rear side of the drying chamber. The hot air blower is equipped with a controller. The temperature sensor is electrically connected to the hot air blower through the controller. The hot air blower is used for drying after the common mode inductor is soldered. The temperature sensor monitors the temperature inside the drying chamber in real time and feeds it back to the controller to control the hot air blower to ensure the drying effect.

[0006] To further explain, it also includes protective pads. Each pneumatic gripper has a protective pad fixedly connected to its gripping surface. The protective pads can prevent the pneumatic grippers from damaging the surface of the common-mode inductor when gripping it.

[0007] Further explanation: It also includes a collection box. A collection box is fixedly connected to the right rear side of the workbench. The collection box is located below the guide plate and is used to collect common mode inductors or waste materials that slide down from the guide plate during the processing.

[0008] To further explain, it also includes a fume purifier. A fume purifier is installed on the upper rear side of the soldering furnace. The controller is electrically connected to the fume purifier. During the soldering process, the controller can activate the fume purifier as needed to purify the generated fumes.

[0009] To further explain, it also includes a protective shell, which is fixedly connected between the two support frames. The protective shell is located outside the pulley assembly and can protect the pulley assembly, preventing accidental contact by operators and preventing dust and other contaminants from entering and affecting the normal operation of the pulley assembly.

[0010] Beneficial effects: 1. The extension rod of the electric push rod drives the pneumatic gripper to the placement rack, clamps the common mode inductor and moves it. The motor drives the pulley set to rotate the lead screw, and the sliding block moves to the flux rack, so that the common mode inductor is immersed in flux. Then it is moved to the soldering furnace for soldering. After soldering, the solder liquid is automatically replenished in a quantitative manner, which overcomes the uncertainty of manual operation and effectively avoids problems caused by too much or too little solder.

[0011] 2. The hot air generated by the hot air blower dries the common mode inductor that has just been soldered. The temperature sensor monitors the temperature inside the drying chamber in real time to speed up the drying process and improve the soldering quality. Attached Figure Description

Detailed Implementation

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0017] Example: A quantitative feeding device for soldering multilayer common mode inductors, such as... Figure 1-3As shown, the system includes a workbench 1, a placement rack 101, a common-mode inductor 102, a flux rack 103, a soldering furnace 104, a conveyor belt 105, a guide plate 106, a support frame 2, a motor 3, a lead screw 4, a pulley assembly 5, a sliding block 6, an electric push rod 7, a pneumatic gripper 8, a load cell 9, a solder storage tank 10, and a conveying pipe 11. The placement rack 101 is mounted on the top front side of the workbench 1. The placement rack 101 has multiple placement slots, each holding a common-mode inductor 102. The flux rack 103 is mounted on the top front side of the workbench 1. A flux holder 103 is located behind the placement rack 101. A soldering furnace 104 is installed on the top center of the workbench 1, behind the flux holder 103. A conveyor belt 105 is installed on the rear side of the workbench 1, and a guide plate 106 is installed on the right side of the conveyor belt 105. Support frames 2 are symmetrically fixedly connected to the top of the workbench 1. A motor 3 is fixedly connected to the rear side of the left support frame 2. Lead screws 4 are rotatably connected to the top of each support frame 2. The output shaft of the motor 3 is connected to the left side of the support frame 101. The lead screw 4 is fixedly connected, and a pulley set 5 is provided between the two lead screws 4. The pulley set 5 is located on the rear side of the two support frames 2. The pulley set 5 enables the two lead screws 4 to rotate synchronously. Each support frame 2 is slidably connected to a sliding block 6, which is threadedly connected to the lead screw 4. When the lead screw 4 rotates, the sliding block 6 can move up and down along the support frame 2 under the action of threaded transmission. Three sets of electric push rods 7 are fixedly connected to the bottom of the sliding block 6. The telescopic rods of the electric push rods 7 are all fixedly connected to multiple pneumatic... The movable gripper 8 is used to grasp and move the common mode inductor 102. A weighing sensor 9 is installed at the bottom of the soldering furnace 104 to monitor the amount of solder in the furnace in real time for precise control of solder addition. A solder storage tank 10 is placed on the right side of the workbench 1. One end of the conveying pipe 11 is connected to the storage tank 10, and the other end of the conveying pipe 11 is connected to the inlet of the soldering furnace 104. The controller is electrically connected to the motor 3, the electric push rod 7, and the pneumatic gripper 8, enabling coordinated operation of all components. A protective pad 15 is also included, fixedly connected to the gripping surface of each pneumatic gripper 8. A protective shell 18 is also included, fixedly connected between the two support frames 2, and located outside the pulley assembly 5.

[0018] When using this device, the common-mode inductor 102 to be soldered is placed sequentially in the placement slot on the placement rack 101, ensuring stable placement for easy subsequent gripping. The electric push rod 7 is activated by the controller, and its telescopic rod extends, causing multiple pneumatic grippers 8 to descend to the position of the placement rack 101. After descending to a suitable height, the pneumatic grippers 8 begin to close, with the clamping surface equipped with the protective pad 15 clamping the common-mode inductor 102 to ensure a secure grip. Without damaging the surface of the common-mode inductor 102, the electric push rod 7 drives the pneumatic gripper 8 and the common-mode inductor 102 to move upward. Subsequently, the motor 3 is started, and the motor 3 drives the pulley group 5 to rotate, causing the two lead screws 4 to rotate synchronously. The rotation of the lead screws 4 drives the sliding block 6 to move backward along the support frame 2 to above the flux holder 103, moving the common-mode inductor 102 downward so that the part to be soldered is immersed in flux, ensuring uniform soldering. After the common-mode inductor 102 is coated with flux and left to stand for an appropriate time, it is moved upwards to allow excess flux to drip off naturally, preventing excessive flux from affecting subsequent soldering and welding quality. The motor 3 is then restarted, and the sliding block 6 moves the flux-coated common-mode inductor 102 above the soldering furnace 104. A weighing sensor 9 is installed at the bottom of the soldering furnace 104 to monitor the weight of the solder liquid inside in real time, thus controlling the soldering of the common-mode inductor 102. The solder joint is immersed in the solder liquid in the soldering furnace 104, so that the solder liquid fully wets the soldering part and achieves a good soldering effect. After the soldering is completed, the solder liquid adheres to the common mode inductor 102. The weighing sensor 9 detects that the weight of the soldering furnace 104 has decreased. The controller controls the solder liquid in the storage tank 10 to be transported into the soldering furnace 104 through the delivery pipe 11 for quantitative replenishment, so that the weight of the solder liquid is restored to the initial set value, thereby ensuring that the amount of solder liquid is relatively stable for each subsequent soldering.

[0019] like Figure 1 and Figure 3As shown, the system also includes a drying chamber 12, a temperature sensor 13, and a hot air blower 14. The drying chamber 12 is fixedly connected to the top rear side of the workbench 1. The drying chamber 12 is located behind the soldering furnace 104 and in front of the conveyor belt 105. The temperature sensor 13 is installed on the right side of the drying chamber 12. The hot air blower 14 is fixedly connected to the rear side of the drying chamber 12. The hot air blower 14 is equipped with a controller. The temperature sensor 13 is electrically connected to the hot air blower 14 through the controller. The hot air blower 14 is used for drying the common mode inductor 102 after soldering. The temperature sensor 13 monitors the temperature inside the drying chamber 12 in real time and feeds it back to the controller to control the operation of the hot air blower 14 to ensure the drying effect. A collection box 16 is also included. The collection box 16 is fixedly connected to the right rear side of the workbench 1 and is located below the guide plate 106.

[0020] The sliding block 6 moves the common mode inductor 102 into the drying chamber 12. The hot air blower 14 is started by the control device, and the hot air generated by the hot air blower 14 enters the drying chamber 12 to dry the common mode inductor 102 that has just been soldered. The temperature sensor 13 monitors the temperature inside the drying chamber 12 in real time to ensure that the temperature is kept within a suitable range for drying solder, thereby accelerating the drying speed of the solder and improving the soldering quality. After drying is completed, the motor 3 is started again, and the sliding block 6 moves the pneumatic gripper 8 to move the soldered common mode inductor 102 above the conveyor belt 105. The pneumatic gripper 8 releases, placing the common mode inductor 102 onto the conveyor belt 105. The conveyor belt 105 starts to operate, transporting the common mode inductor 102 to the guide plate 106, where it slides along the guide plate 106 into the collection box 16 for collection and sorting.

[0021] like Figure 1 As shown, it also includes a fume purifier 17, which is installed on the upper rear side of the soldering furnace 104, and the controller is electrically connected to the fume purifier 17.

[0022] The fume purifier 17 can effectively adsorb and filter the fume particles generated during the soldering process, purifying the air environment of the work area.
