An automatic soldering device for chip transformers

Abstract

This utility model relates to the field of transformer manufacturing technology, specifically an automatic soldering device for surface-mount transformers. It includes a base, a solder bath fixedly installed on the rear side of the top of the base, and a cooling tank fixedly installed on the top of the base in front of the solder bath. A conveyor belt is positioned above the top of the base, in front of the cooling tank. This automatic soldering device for surface-mount transformers, through the coordinated use of a solder bath, servo motor, heating rod, stirring shaft, stirring roller, and temperature sensor, effectively controls and stirs the temperature of the molten solder in the solder bath. The temperature sensor monitors the molten solder temperature in real time, and by adjusting the power of the heating rod, the temperature of the molten solder can be precisely stabilized within a suitable process range.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 One embodiment provided by this utility model:

[0028] An automatic soldering device for chip transformers, comprising:

[0029] A base 1 has a solder pool 6 fixedly installed on the rear side of the top of the base 1. A cooling pool 7 is fixedly installed on the top of the base 1 in front of the solder pool 6. A conveyor belt 8 is set above the top of the base 1 in front of the cooling pool 7. A placement rack 9 is fixedly installed on the top of the base 1 in front of the conveyor belt 8.

[0030] Both sides of the top of the base 1 are fixedly installed with slide rod brackets 2, and sliders 5 are slidably sleeved on the two slide rod brackets 2. A movable frame 14 is fixedly installed between the tops of the two sliders 5. A longitudinal drive mechanism is provided on the back of the base 1, and a vertical drive mechanism is provided on the movable frame 14.

[0031] A stirring shaft 17 is rotatably installed inside the solder pool 6. A servo motor 15 is fixedly installed on one side of the solder pool 6, and the drive end of the servo motor 15 passes through the solder pool 6 and extends into the interior of the solder pool 6 and is fixedly connected to one end of the stirring shaft 17. Several stirring rods 18 are fixedly installed on the outer wall of the stirring shaft 17. A temperature sensor 19 is fixedly installed on the lower side of one side of the inner wall of the solder pool 6. Heating rods 16 are fixedly embedded in the front and back of the inside of the solder pool 6.

[0032] In one embodiment, the longitudinal drive mechanism includes a fixed frame 3, which is fixedly installed on the back of the base 1. A first electric telescopic rod 4 is fixedly installed on the fixed frame 3, and the drive end of the first electric telescopic rod 4 is fixedly connected to the back of the movable frame 14.

[0033] In one preferred embodiment, the vertical drive mechanism includes a second electric telescopic rod 12, which is fixedly installed on the top of the movable frame 14. The drive end of the second electric telescopic rod 12 passes through the movable frame 14 and extends into the interior of the movable frame 14. A clamping frame 10 is fixedly installed on the drive end of the second electric telescopic rod 12. A clamping assembly 11 is provided inside the clamping frame 10. For the specific structure and working principle of the clamping assembly 11, please refer to the clamping mechanism in the prior art CN220880867U. This application will not elaborate further.

[0034] In one embodiment, guide rods 13 are fixedly installed on both sides of the top of the clamping frame 10. The movable frame 14 has sliding holes corresponding to the position and number of guide rods 13. The movable frame 14 is slidably connected to the guide rods 13 through the sliding holes. The guide rods 13 cooperate with the sliding holes to ensure the stability and straightness of the clamping frame 10 when it moves, so that the clamping assembly 11 can be accurately positioned and operated, and the accuracy of workpiece clamping and welding can be improved.

[0035] In one preferred embodiment, the heating rod 16 is shaped like a serpentine coil. The serpentine coil heating rod 16 can increase the contact area with the molten solder, making the heating more uniform and efficient, and can also reduce local overheating, thereby improving the soldering quality and the stability of the molten solder.

[0036] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control, and existing publicly available power connection technologies are not elaborated upon here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. During use, the temperature of the solder bath 6 is monitored in real time by the internal temperature sensor 19. The heating rod 16 is adjusted to achieve precise control of the solder bath 6 temperature. When the solder bath temperature is detected to be lower than a preset value, the heating power of the heating rod 16 is automatically increased to accelerate heat input; when the temperature is higher than the preset value, the heating power is reduced to prevent excessive temperature, thus ensuring that the solder bath temperature is stably maintained within a suitable process range. Simultaneously, the servo motor 15 can be controlled to start operation. The drive end of the servo motor 15 drives the stirring shaft 17 to rotate, and the rotation of the stirring shaft 17 in turn drives the stirring roller 18 to rotate synchronously. The rotation of the stirring roller 18 within the solder bath 6 promotes convection of the molten solder, effectively making the temperature distribution of the molten solder more uniform, preventing local overheating or undercooling, and making the chemical composition distribution of the molten solder more consistent. At the same time, it significantly improves the fluidity of the molten solder, ultimately ensuring the stability and welding quality of the transformer soldering process.

[0037] In the specific process of soldering transformer workpieces, the transformer workpiece to be soldered is first placed on the placement rack 9. Then, the control system issues a command to activate the first electric telescopic rod 4, whose drive end pushes the movable frame 14 to move longitudinally. The movable frame 14 drives the slider 5 to slide smoothly on the slide bar frame 2. Simultaneously, the movement of the movable frame 14 drives the clamping frame 10 to move synchronously via the second electric telescopic rod 12, thereby moving the clamping frame 10 and the clamping assembly 11 to directly above the placement rack 9. At this point, the control system issues another command to activate the second electric telescopic rod 12, whose drive end moves the clamping frame 10 and the clamping assembly 11 downwards until the clamping assembly 11 precisely clamps the workpiece on the placement rack 9. After clamping, the system controls the clamped workpiece to move above the solder bath 6, immersing the workpiece leads into the solder bath 6 for precise soldering. After the soldering process is completed, the workpiece is moved into the cooling bath 7 for rapid cooling to ensure soldering quality. Finally, the cooled and processed workpiece is conveyed out via the conveyor belt 8. In the entire automated soldering process, the first electric telescopic rod 4 and the second electric telescopic rod 12 are used as driving components. Compared with the traditional independent motor driving method, the electric telescopic rod has higher practicality and accuracy in displacement control, which can effectively improve the quality and efficiency of soldering operations.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
