Description

Technical Field

[0001] This invention relates to the field of automatic soldering machine technology, and more specifically, to an automatic soldering machine for power supply boxes and electronic components. Background Technology

[0002] The core of the automatic soldering machine for power supply boxes and electronic components is to replace manual labor with automatic soldering iron soldering machines, selective wave soldering machines, and laser soldering machines to complete spot soldering, drag soldering, and tin addition of components, pins, and connectors.

[0003] Chinese patent application CN119187750A discloses a computer circuit board soldering equipment and solder joint inspection method, including a machine base. A stand is fixedly assembled on the surface of the machine base, and a second track is fixedly assembled on one side of the top of the stand. A slider is slidably assembled on one side of the second track via a track machine. A third track is fixedly assembled on the outside of the slider. A side frame is slidably assembled on the outside of the third track via a track machine. A laser generator for generating laser light is fixedly assembled below the side frame. A solder bar feeding mechanism for conveying solder bars is fixedly assembled on the outside of the side frame. A rolling mechanism for changing the surface morphology of the solder bars is provided inside the solder bar feeding mechanism. A temperature control mechanism for controlling the cooling rate of the solder joint is provided from one side to the bottom of the laser generator.

[0004] The above technical solutions can prepare microgrooves on the surface of solder bars, improve light energy absorption, and solve the problem of rapid cooling of solder joints. However, when traditional soldering machines solder the pins of electronic components in power supply boxes, they first insert the pins of the components to be soldered into the fixing holes, then manually intervene by blowing away the dirt on the pins to be soldered with a blower, and then hold the soldering gun head to solder the pins. After the soldering is completed, the soldering gun head is removed, allowing the soldered pins to cool and solidify automatically. After the soldering gun head is removed, the high surface temperature of the soldered pins can cause solder wires to stick and pull at the soldering gun head and the soldered pins. The pulled solder wires may cause adjacent pins of electronic components to connect, resulting in damage to the power supply components. Moreover, the soldering gun head generates soldering fumes during the soldering process, which will affect the quality of the working environment over a long period of time. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) When using this automatic soldering machine for electronic components in a power supply box, the soldering head moves downwards. The soldering head first squeezes two inclined plates, and the rotation of the inclined plates causes two movable plates and two cutting blades to rotate in opposite directions. The soldering head moves downwards and contacts the soldering pins, and the soldering head solders the pins. After the soldering head has finished soldering the pins, the telescopic device resets, taking the soldering head back to its original position. During the reset process, the two cutting blades move towards each other under the action of the spring shaft, cutting off the pulled solder wires. Compared with traditional handheld soldering guns, this soldering machine can cut off the pulled solder wires, avoiding short circuits caused by solder wire sticking to the components, ensuring the soldering quality of the power supply components, and ensuring the normal use of the power supply components in the later stages.

[0019] 2) When using this automatic soldering machine for electronic components in the power supply box, during the movement of the soldering head, the controller first controls the air pump to work. The air pump delivers gas to the air inlet pipe. The gas enters the interior of the fixed box through the vertical pipe. Then, the gas enters the gas collection pipe through the hose and flow control valve. The gas inside the gas collection pipe enters multiple connecting pipes through two arc-shaped boxes and two horizontal frame boxes. The multiple connecting pipes blow air simultaneously to clean the soldering pins, ensuring the cleanliness of the soldering pins before soldering, preventing soldering cavitation in the pins, and ensuring the soldering quality of the power supply components by the soldering machine body.

[0020] 3) When the automatic soldering machine for electronic components in this power supply box is in use, the soldering head generates soldering waste gas during the soldering process of the pins. The motor rotates, which drives gear two to rotate. Gear two rotates, which in turn drives gear one to rotate, so that the vertical pipe and the suction pipe are connected. The soldering waste gas enters multiple connecting pipes, the horizontal frame box and the arc-shaped box and enters the gas collection pipe. The waste gas inside the gas collection pipe enters the suction pipe through the hose, the fixed box and the vertical pipe. The waste gas is then sent to the waste gas treatment equipment for treatment through the suction pipe.

[0021] 4) When using the automatic soldering machine for electronic components in this power supply box, during the soldering head reset process, the air pump delivers gas to the air inlet pipe again. The gas enters the interior of the fixed box through the vertical pipe, and then enters the gas collection pipe through the hose and flow control valve. The gas inside the gas collection pipe enters multiple connecting pipes through two arc-shaped boxes and two horizontal frame boxes. The multiple connecting pipes blow air simultaneously to cool and shape the soldering pins. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 9An automatic soldering machine for power supply boxes and electronic components includes a soldering machine body 1 and power supply components 2 placed on its surface. The power supply components 2 are conventional power supply components in the prior art. A vertically movable lifting rod 3 is provided above the power supply components 2. An extension rod 4 is fixedly installed on the bottom surface of the lifting rod 3, and a soldering head 5 is fixedly installed on the bottom surface of the extension rod 4. The soldering head 5 is a conventional soldering head in the prior art. Fixing frames 6 are symmetrically fixedly installed on the surface of the extension rod 4. Through-type sliding rods 7 are slidably connected to the surfaces of both fixing frames 6. The sliding rods 7 are used to guide the movement of a protective box 8. The protective box 8 is fixedly installed on the bottom surface of both sliding rods 7. The protective box 8 provides protection for the collection of exhaust gases. The protective box 8 is designed to prevent eye damage from the strong light generated during soldering by the soldering head 5. The protective box 8 is hemispherical, with multiple support rods 9 fixedly installed on its bottom surface. The support rods 9 allow impurities to be blown out through the gaps between them when cleaning the pin area. Multiple through-type connecting pipes 10 are symmetrically fixedly installed on the surface of the protective box 8. One section of the connecting pipe 10 inside the protective box 8 has an arc-shaped bend, allowing the gas blown out by the connecting pipe 10 to directly act on the pin area. The inner wall of the protective box 8 is symmetrically rotatably connected to movable plates 11. A cutting blade 12 for cutting solder wire is fixedly installed on the bottom surface of each of the two movable plates 11. The cutting blade 12 is a conventional cutting blade 12 in the prior art. The top surface of the moving plate 11 is fixedly equipped with ramp plates 13. A fixed box 16 is provided on one side of the lifting rod 3. A turntable 17 is rotatably connected to the surface of the fixed box 16. The turntable 17 and the fixed box 16 are rotatably and sealingly connected. A vertical pipe 18 communicating with the fixed box 16 is fixedly installed on the surface of the turntable 17. A fixed plate 19 is provided above the vertical pipe 18. A through-type air inlet pipe 20 and an air intake pipe 21 are fixedly installed on the surface of the fixed plate 19. The vertical pipe 18 is interchangeably connected to the air inlet pipe 20 and the air intake pipe 21. A rotating groove 22 is opened on the bottom surface of the fixed plate 19. The top of the vertical pipe 18 is rotatably connected to the rotating groove 22. The soldering head 5 continues to move downward. The movement of the soldering head 5 first squeezes the two ramp plates 13. 3. The ramp plate 13 rotates, causing the two movable plates 11 and the two cutting blades 12 to rotate in opposite directions. The soldering head 5 moves downward and contacts the soldering pin. The soldering head 5 works to solder the pin. After the soldering head 5 has finished soldering the pin, the telescopic device 35 resets, taking the soldering head 5 back to its original position. During the reset of the soldering head 5, the two cutting blades 12 move towards each other under the action of the spring shaft 40. The two cutting blades 12 move towards each other to cut the pulled solder wire. Compared with traditional handheld soldering guns, the soldering machine body 1 can cut the pulled solder wire, avoiding short circuits caused by solder wire sticking to electrical components. This ensures the soldering quality of the power supply component 2 and guarantees the normal use of the power supply component 2 in the future.During the movement of the soldering head 5, the controller 38 first controls the air pump 36 to work, which delivers gas to the air inlet pipe 20. The gas enters the fixed box 16 through the vertical pipe 18, and then enters the gas collecting pipe 14 through the hose 25 and the flow control valve 15. The gas inside the gas collecting pipe 14 enters multiple connecting pipes 10 through two arc-shaped boxes 24 and two horizontal frame boxes 23. The multiple connecting pipes 10 simultaneously blow air to clean the soldering pins, ensuring the cleanliness of the soldering pins before soldering, preventing soldering cavitation in the pins, and ensuring the soldering quality of the soldering machine body 1 on the power supply components 2. During the soldering process of the soldering head 5, soldering waste gas is generated. The motor 32 rotates, driving the gear 2 30 to rotate, and the gear 2 30 rotates, driving the gear 1 29 to rotate. This connects the vertical pipe 18 to the suction pipe 21. Welding exhaust gas enters multiple connecting pipes 10, the horizontal frame box 23, and the arc-shaped box 24, then enters the gas collecting pipe 14. The exhaust gas inside the gas collecting pipe 14 passes through the hose 25, the fixed box 16, and the vertical pipe 18 into the suction pipe 21, which then sends the exhaust gas to the exhaust gas treatment equipment for processing. During the resetting process of the solder head 5, the air pump 36 again supplies gas to the air inlet pipe 20. The gas passes through the vertical pipe 18 into the fixed box 16, and then through the hose 25 and the flow control valve 15 into the gas collecting pipe 14. The gas inside the gas collecting pipe 14 passes through the two arc-shaped boxes 24 and the two horizontal frame boxes 23 into the multiple connecting pipes 10. Simultaneous air blowing through the multiple connecting pipes 10 cools and shapes the welded pin area.

[0034] The protective box 8 is provided with an air collection pipe 14. A flow control valve 15 is fixedly installed on the surface of the air collection pipe 14. A hose 25 is fixedly installed between the flow control valve 15 and the fixed box 16. One end of the hose 25 is connected to the flow control valve 15, and the other end of the hose 25 is connected to the fixed box 16. The flow control valve 15 is a conventional flow control valve in the prior art. Before welding the pin, the opening of the flow control valve 15 is enlarged so that the gas can better clean the impurities at the pin. When cooling the pin, the opening of the flow control valve 15 is reduced to prevent excessive air blowing from causing a dent at the weld.

[0035] The protective box 8 has two horizontal frame boxes 23 symmetrically arranged on its exterior. The horizontal frame boxes 23 are fixedly connected to and communicate with multiple connecting pipes 10. Two arc-shaped boxes 24 are symmetrically fixedly installed on the surface of the two horizontal frame boxes 23 and communicate with them. Both arc-shaped boxes 24 are fixedly connected to the gas collecting pipe 14 and communicate with each other.

[0036] A horizontal plate 26 is fixedly installed between the fixed box 16 and the lifting rod 3. A fixing ring 27 is provided below the fixed plate 19. A horizontal plate 28 is fixedly installed between the fixing ring 27 and the lifting rod 3. A gear 29 is rotatably connected to the bottom surface of the fixing ring 27. The top of the vertical tube 18 passes through the gear 29.

[0037] A gear 30 meshing with a gear 29 is rotatably connected to the lower part of the horizontal plate 28. A motor 32 is fixedly mounted on the surface of the horizontal plate 28. The motor 32 is a conventional forward and reverse reversing motor in the prior art. The output end of the motor 32 is fixedly connected to the gear 30.

[0038] A frame plate 31 is fixedly installed between the fixed plate 19 and the horizontal plate 28. A multi-directional movable frame 33 is fixedly installed on the surface of the soldering machine body 1. A movable frame 34 is fixedly installed on the surface of the multi-directional movable frame 33. A telescopic device 35 is fixedly installed on the surface of the movable frame 34. The telescopic end of the telescopic device 35 is fixedly connected to the lifting rod 3. The telescopic device 35 is a conventional electrically controlled push rod in the prior art.

[0039] A blowing pump 36 and a suction pump 37 are symmetrically fixedly installed on the surface of the movable frame 34. The air outlet of the blowing pump 36 is connected to the air inlet pipe 20 through a pipeline, and the inlet of the suction pump 37 is connected to the suction pipe 21 through a wire. The blowing pump 36 is a conventional blowing pump 36 in the prior art, and the suction pump 37 is a conventional suction pump 37 in the prior art.

[0040] The inlet of the blowing pump 36 is connected to the air supply equipment, and the outlet of the suction pump 37 is connected to the exhaust gas treatment equipment. The exhaust gas treatment equipment is a conventional gas treatment device in the prior art, which will not be described in detail here.

[0041] A controller 38 is fixedly mounted on the surface of the movable frame 34. The controller 38 is a conventional programmable control device in the prior art. The controller 38 is electrically connected to the blowing pump 36 via wires, the controller 38 is electrically connected to the suction pump 37 via wires, the controller 38 is electrically connected to the telescopic device 35 via wires, and the controller 38 is electrically connected to the flow control valve 15 via wires.

[0042] The surface of the protective box 8 has a through slot 39, which is slidably connected to the extension rod 4. A spring shaft 40 is provided between the movable plate 11 and the inner wall of the protective box 8. The spring shaft 40 is a conventional elastic reset shaft in the prior art. The movable plate 11 is rotatably connected to the inner wall of the protective box 8 through the spring shaft 40. An elastic spring 41 is sleeved on the surface of the slide rod 7. One end of the elastic spring 41 is fixedly connected to the fixing frame 6, and the other end of the elastic spring 41 is fixedly connected to the surface of the protective box 8. The elastic spring 41 is used to reset the protective box 8.

[0043] The steps for using this invention are as follows: When using this automatic soldering machine for electronic components in a power supply box, in the initial position, the top of the vertical tube 18 is connected to the air inlet pipe 20. When soldering the pins of the power supply component 2, first place the power supply component 2 on the surface of the soldering machine body 1. Then, the movable frame 34 moves on the surface of the multi-directional movable frame 33, so that the protective box 8 moves above the soldering pins. Operate the controller 38, which controls the telescopic device 35 to extend. The telescopic device 35 extends, causing the lifting rod 3 and the extension rod 4 to move downwards. The extension rod 4 moves the sliding rod 7 and the protective box 8 downwards. The downward movement of the protective box 8 causes the support rod 9 to move downwards. When the support rod 9 contacts the surface of the power supply component 2, the center of the protective box 8 is aligned with the soldering pin. As the telescopic device extends... As the extension rod 4 continues to descend, the protective box 8 moves upward, causing the sliding rod 7 to move on the fixed frame 6 and compress the elastic spring 41. The extension rod 4 moves downward, causing the soldering head 5 to move downward. During the movement of the soldering head 5, the controller 38 first controls the air pump 36 to operate, which delivers gas to the air inlet pipe 20. The gas enters the fixed box 16 through the vertical pipe 18, and then enters the gas collecting pipe 14 through the hose 25 and the flow control valve 15 (note that the flow control valve 15 is currently at its maximum opening). The gas inside the gas collecting pipe 14 enters multiple connecting pipes 10 through two arc-shaped boxes 24 and two horizontal frame boxes 23. Simultaneous air blowing through multiple connecting pipes 10 cleans the welding pin area, removing dust from the support... After the gap between rods 9 is blown out and the dust is cleaned, the air pump 36 stops working, and the soldering head 5 continues to move downward. The movement of the soldering head 5 first squeezes the two inclined plates 13. The rotation of the inclined plates 13 causes the two movable plates 11 and the two cutting blades 12 to rotate in opposite directions. The soldering head 5 continues to move downward. Before the soldering head 5 contacts the pin to be soldered, the controller 38 controls the motor 32 to rotate forward (the rotation of the motor 32 is controllable). The rotation of the motor 32 causes the gear 2 30 to rotate. The rotation of the gear 2 30 causes the gear 1 29 to rotate. The rotation of the gear 1 29 causes the vertical tube 18 to rotate 180 degrees. After the vertical tube 18 is connected to the suction pipe 21, the rotation of the vertical tube 18 causes the turntable 17 to rotate on the surface of the fixed box 16. The soldering head 5 continues to move downward. The soldering head 5 contacts the pin and performs soldering on it. During this process, soldering head 5 generates soldering fumes. At this time, controller 38 controls air pump 37 to operate. The soldering fumes enter multiple connecting pipes 10, horizontal frame box 23, and arc-shaped box 24, then enter the gas collection pipe 14. The fumes inside the gas collection pipe 14 pass through hose 25, fixed box 16, and vertical pipe 18 into the suction pipe 21. The suction pipe 21 then sends the fumes to the waste gas treatment equipment for processing. After soldering head 5 completes the soldering, telescopic device 35 resets, taking soldering head 5 with it. During the reset process, controller 38 controls motor 32 to reverse. Motor 32 rotates, causing gear 2 30 to rotate, which in turn rotates gear 1 29.After gear 29 rotates, it causes vertical pipe 18 to rotate 180 degrees and reconnects with air inlet pipe 20. When solder head 5 leaves the two ramps 13, the two cutting blades 12 move towards each other and reset under the action of spring shaft 40. The two cutting blades 12 cut the pulled solder wire. After the solder wire is cut, as solder head 5 continues to reset, air pump 36 again supplies gas to air inlet pipe 20 (when air pump 36 works again, controller 38 controls the flow control valve 15 to reduce its opening). The gas enters the fixed box 16 through vertical pipe 18, and then enters the gas collecting pipe 14 through hose 25 and flow control valve 15 (note that flow control valve 15 is currently at its minimum opening). The gas inside gas collecting pipe 14 enters multiple connecting pipes 10 through two arc-shaped boxes 24 and two horizontal frame boxes 23. Multiple connecting pipes 10 simultaneously blow air to cool and shape the soldering pins. Finally, the entire soldering machine body 1 is fully reset.

[0044] Through the above technical solution, the soldering head 5 moves downward. The movement of the soldering head 5 first squeezes the two inclined plates 13. The inclined plates 13 rotate, causing the two movable plates 11 and the two cutting blades 12 to rotate in opposite directions. The soldering head 5 moves downward and contacts the soldering pin. The soldering head 5 works to solder the pin. After the soldering head 5 has finished soldering the pin, the telescopic device 35 resets, taking the soldering head 5 back to its original position. During the reset process of the soldering head 5, the two cutting blades 12 move towards each other under the action of the spring shaft 40. The two cutting blades 12 move towards each other and cut the pulled solder wire. Compared with traditional handheld soldering guns, the soldering machine body 1 can cut the pulled solder wire, avoiding short circuits caused by solder wire sticking to electrical components, ensuring the soldering quality of the power supply component 2, and ensuring the normal use of the power supply component 2 in the later stage.

[0045] During the movement of the soldering head 5, the controller 38 first controls the air pump 36 to work, and the air pump 36 delivers gas to the air inlet pipe 20. The gas enters the interior of the fixed box 16 through the vertical pipe 18, and then the gas enters the interior of the gas collection pipe 14 through the hose 25 and the flow control valve 15. The gas inside the gas collection pipe 14 enters the interior of multiple connecting pipes 10 through two arc-shaped boxes 24 and two horizontal frame boxes 23. The multiple connecting pipes 10 blow air at the same time to clean the welding pin parts, ensuring the cleanliness of the soldering pins before welding, preventing welding cavitation in the pins, and ensuring the welding quality of the soldering machine body 1 to the power supply components 2.

[0046] During the soldering process of the soldering head 5, welding exhaust gas is generated. The motor 32 rotates, which drives the gear 20 to rotate. The gear 20 rotates, which in turn drives the gear 19 to rotate, so that the vertical pipe 18 is connected to the suction pipe 21. The welding exhaust gas enters the multiple connecting pipes 10, the horizontal frame box 23 and the arc-shaped box 24 and enters the gas collection pipe 14. The exhaust gas inside the gas collection pipe 14 enters the suction pipe 21 through the hose 25, the fixed box 16 and the vertical pipe 18. The exhaust gas is then sent to the exhaust gas treatment equipment for treatment through the suction pipe 21.

[0047] During the resetting process of the solder head 5, the air pump 36 delivers gas to the air inlet pipe 20 again. The gas enters the interior of the fixed box 16 through the vertical pipe 18, and then enters the interior of the gas collection pipe 14 through the hose 25 and the flow control valve 15. The gas inside the gas collection pipe 14 enters the interior of multiple connecting pipes 10 through the two arc-shaped boxes 24 and the two horizontal frame boxes 23. The multiple connecting pipes 10 blow air at the same time to cool and shape the soldering pin part.
