Description

Technical Field

[0001] This utility model relates to an automatic soldering machine, specifically an automatic soldering machine with fume purification effect, belonging to the technical field of soldering machines. Background Technology

[0002] An automatic soldering machine is an automated soldering device that heats solder wire until it melts into a liquid state, then precisely sprays the molten solder through a nozzle onto the electronic components to be soldered. The nozzle contains a gas nozzle that propels the molten solder particles onto the components. The nozzle position, angle, and spraying time are all controlled by a program to ensure accurate solder placement. After soldering is complete, the solder head heater automatically shuts off, the solder wire cools, and quickly solidifies, completing the soldering of the electronic components. The entire process is automated, enabling efficient and accurate soldering operations.

[0003] In existing technologies, such as the automatic soldering machine disclosed in CN215588531U, there is a worktable with a shelf on it. A soldering section is located above the shelf, and the soldering section is connected to a drive mechanism that moves it closer to or further away from the shelf. The fume extraction device includes a universal metal flexible tube. This universal metal flexible tube is a long tube that can be bent arbitrarily and maintain its shape. One end near the frame is fixedly connected to the corresponding end of the frame, and the other end away from the frame is connected to a fume hood. The opening of the fume hood is outwardly flared and faces the shelf. The portion away from the opening is connected to an extraction pipe. This extraction pipe draws the generated fumes out and discharges them to the outside, preventing the fumes from harming human health.

[0004] Although the above-mentioned technical solutions can extract and discharge the generated smoke to the outside through the exhaust pipe to avoid the smoke being harmful to human health, they can only transfer the smoke, and the smoke still remains in the air. They cannot purify harmful substances such as ozone in the smoke, and their practicality is poor. In view of this, an automatic soldering machine with smoke purification effect is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem that the aforementioned automatic soldering machine can only transfer flue gas, leaving the smoke still in the air and unable to purify harmful substances such as ozone in the smoke, resulting in poor practicality.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an automatic soldering machine with fume purification effect, comprising a device frame, an adjustment frame fixed at the upper end of the device frame, an installation plate fixed inside the adjustment frame, an adjustment cylinder fixed to the lower surface of the installation plate by bolts, a connecting plate fixed to the telescopic end of the adjustment cylinder, a welding mechanism for welding workpieces provided on the right side of the connecting plate, and an adjustment mechanism for adjusting the welding mechanism provided on one side of the adjustment frame.

[0007] The welding mechanism includes a purification component, which is fixed to the right side of the connecting plate. An exhaust fan is fixed to the upper end of the purification component, an activated carbon plate is fixed to the inner wall of the purification component, a filter screen is fixed to the lower end of the activated carbon plate, and a coarse filter screen is fixed to the lower surface of the filter screen.

[0008] As a further embodiment of this utility model: a fixing plate is threadedly connected to the lower surface of the purification component, and an air intake pipe communicating with the purification component is provided at the lower end of the fixing plate.

[0009] As a further improvement of this utility model, a solder head is fixed to the lower surface of the connecting plate by bolts.

[0010] As a further embodiment of this utility model: both ends of the device frame are fixed with clamping electric cylinders by bolts, and the telescopic end of the clamping electric cylinder is fixed with a clamping plate that is slidably connected to the device frame.

[0011] As a further improvement of this utility model: the adjustment mechanism includes two stepper motors, and both stepper motors are fixed to one side of the adjustment frame by screws.

[0012] As a further improvement of this utility model, the power output shafts of both stepper motors are fixed with drive pulleys.

[0013] As a further improvement of this utility model: a belt is connected to one side of each of the two driving pulleys, and an idler pulley that is rotatably connected to the side wall of the belt is connected to the adjusting frame.

[0014] The beneficial effects of this utility model are: the exhaust fan installed in the purification component, in conjunction with the suction pipe, can draw smoke into the purification component, filter larger impurities in the smoke through the coarse filter screen, filter smaller impurities through the filter screen plate, and then the ozone in the smoke is adsorbed by the activated carbon plate to achieve the purification effect.

[0015] The independent operation of two stepper motors allows for more flexible movement of complex paths, ensuring soldering results. Since the stepper motors remain stationary, their weight is not required during movement, thus reducing the load. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Example 1

[0022] like Figures 1 to 4 As shown, an automatic soldering machine with fume purification effect includes a device frame 1, an adjustment frame 2 fixed at the upper end of the device frame 1, an installation plate 3 fixed inside the adjustment frame 2, an adjustment cylinder 4 fixed to the lower surface of the installation plate 3 by bolts, a connecting plate 5 fixed to the telescopic end of the adjustment cylinder 4, a welding mechanism for welding workpieces provided on the right side of the connecting plate 5, and an adjustment mechanism for adjusting the welding mechanism provided on one side of the adjustment frame 2.

[0023] The welding mechanism includes a purification component 6, which is fixed to the right side of the connecting plate 5. An exhaust fan 61 is fixed to the upper end of the purification component 6. An activated carbon plate 62 is fixed to the inner wall of the purification component 6. A filter screen plate 63 is fixed to the lower end of the activated carbon plate 62. A coarse filter screen 64 is fixed to the lower surface of the filter screen plate 63. A fixing plate 65 is threadedly connected to the lower surface of the purification component 6. An air intake pipe 66 communicating with the purification component 6 is located at the lower end of the fixing plate 65. A solder head 7 is fixed to the lower surface of the connecting plate 5 by bolts. Clamping cylinders 8 are fixed to both ends of the device frame 1 by bolts. A clamping plate 9, which is slidably connected to the device frame 1, is fixed to the telescopic end of the clamping cylinder 8. When the mounting plate 3 moves, it drives the adjusting cylinder 4 to move synchronously. The adjusting electric cylinder 4 drives the connecting plate 5 to move vertically. The solder head 7 is equipped with a heater and a temperature control device. The heater can quickly heat the solder wire to a temperature above the melting point, and the temperature control device can precisely control the temperature of the solder head 7 to achieve soldering of the workpiece. The fumes generated during soldering are drawn into the purification unit 6 by the exhaust fan 61 installed in the purification unit 6 with the help of the suction pipe 66. The larger impurities in the fumes are filtered by the coarse filter 64, while the smaller impurities are filtered by the filter plate 63. The fumes are then purified by the adsorption of ozone in the fumes by the activated carbon plate 62. The fumes are then discharged to the outside. The fixed plate 65 can be removed from the purification unit 6 to facilitate the replacement of the purification mechanism. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: an adjustment mechanism comprising two stepper motors 21, each fixed to one side of the adjustment frame 2 by screws; a drive pulley 22 fixed to the power output shaft of each stepper motor 21; a belt 23 connected to one side of each drive pulley 22; and an idler pulley 24 rotatably connected to the side wall of the belt 23. The two stepper motors 21 can drive the drive pulleys 22 to rotate, thereby driving the belt 23 to move. The idler pulley 24 ensures the stability of the belt 23's movement. The end of the belt 23 is fixed to the mounting plate 3. When the first stepper motor 21 and the second stepper motor 21 move in opposite directions simultaneously... When the needles rotate, they will pull a portion of the movable mounting plate 3 along the positive X-axis direction via the belt 23. Due to the angle formed by the belts 23 of the two stepper motors 21 on the moving platform, the belts 23 will be displaced in the X-axis direction. When the first stepper motor 21 and the second stepper motor 21 rotate in opposite directions, that is, one rotates counterclockwise and the other rotates clockwise, they will push the mounting plate 3 in opposite directions via the belts 23, thereby producing displacement in the Y-axis direction. The independent operation of the two stepper motors 21 also makes it more flexible to realize the movement of complex paths, ensuring the soldering effect. Moreover, since the stepper motors 21 are fixed, there is no need to carry the weight of the stepper motors 21 during movement, thus reducing the load.

[0025] Working Principle: Before using the automatic soldering machine with fume purification effect, first place the device frame 1 in a suitable position, and place the workpiece to be processed on the device frame 1. The clamping electric cylinder 8 can drive the clamping plate 9 to move, so that the two clamping plates 9 clamp and fix the workpiece. The two stepper motors 21 set on the adjusting frame 2 can drive the drive pulley 22 to rotate, thereby driving the belt 23 to move. The idler pulley 24 can ensure the stability of the belt 23 movement. The end of the belt 23 is fixed to the mounting plate 3. When the first stepper motor 21 and the second stepper motor 21 rotate counterclockwise at the same time, they will pull a part of the moving mounting plate 3 along the positive X-axis direction through the belt 23. Due to the angle formed by the belt 23 of the two stepper motors 21 on the moving platform, the belt 23 will be displaced in the X-axis direction. When the first stepper motor 21 and the second stepper motor 21 rotate in opposite directions, that is, one rotates counterclockwise and the other rotates clockwise, they will push the mounting plate 3 in opposite directions through the belt 23. The upward movement of the stepper motor 21 creates displacement in the Y-axis direction. The independent operation of the two stepper motors 21 allows for more flexible movement of complex paths, ensuring soldering results. Since the stepper motors 21 remain stationary, their weight is not required during movement, thus reducing the load. When the mounting plate 3 moves, it drives the adjusting cylinder 4 to move synchronously, which in turn drives the connecting plate 5 to move vertically. The solder head 7 is equipped with a heater and a temperature control device. The heater can quickly heat the solder wire to a temperature above its melting point, while the temperature control device can precisely control the temperature of the solder head 7 to achieve soldering of the workpiece. The fumes generated during soldering are drawn into the purification unit 6 by the exhaust fan 61 inside the purification unit 6, in conjunction with the suction pipe 66. Larger impurities in the fumes are filtered by the coarse filter 64, while smaller impurities are filtered by the filter plate 63. The fumes are then purified by the adsorption of ozone by the activated carbon plate 62 before being discharged to the outside. The purification mechanism can be easily replaced by removing the fixing plate 65 from the purification unit 6.
