Description

Technical Field

[0001] This invention relates to the field of robotics, specifically to an integrated device for soldering and dispensing inductor pins. Background Technology

[0002] With the development of surface mount technology, reflow soldering technology is increasingly widely used in the chip mounting and soldering process of electronic circuit boards. Reflow soldering can effectively improve the consistency of chip mounting. Typically, the process begins with applying solder paste to the circuit board, followed by placing the chip mounting materials according to the circuit layout, and finally placing the circuit board into a reflow oven to complete the soldering process. For example, patent document CN 219924800U discloses a circuit board reflow oven device, which includes: a reflow oven, a receiving device, a shielding device, a detection device, and a control device. The reflow oven is used to heat the circuit board and transport the heated circuit board outward. The receiving device is used to receive the circuit board transported by the reflow oven and is provided with a material pick-up port. The shielding device includes a driver and a moving part.

[0003] Taking the aforementioned circuit board reflow oven equipment as an example, during the process of soldering inductor pins on the circuit board, in applications with vibration risks (such as automotive electronics), dispensing can greatly enhance the bonding force between the inductor and the PCB board, preventing the pins from breaking due to vibration or impact. However, in the application process of existing circuit board reflow oven equipment, the circuit board needs to be cleaned to remove adhesive impurities and dried before dispensing. This process requires the circuit board to be clamped and lowered multiple times and the circuit board needs to be positioned multiple times, resulting in a long circuit board processing cycle and high time cost.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

[0016] 2. When this application is used, the circuit board is thoroughly dried before moving to the bottom of the dispensing machine under the action of rotation and hot air. A container with pressurization and clamping function is formed by two diversion containers, two one-way valves II and four one-way valves I, which ensures that water and hot air act directly on the surface of the circuit board to be dispensed with glue, so as to accurately rinse and dry the circuit board, reduce water waste, and make the heat in the exhaust gas discharged from the reflow oven meet the needs of warm water rinsing and hot air drying of the circuit board, thereby improving resource efficiency.

When this application is used, the control air pump works to deliver hot air into the distribution container through telescopic tube one, metal tube, distribution box, telescopic tube two and one-way valve one. Due to the one-way conduction characteristic of one-way valve two, the gas inside the distribution container can only be discharged through the small hole. The air intake speed inside the distribution container is much greater than the exhaust speed. High-speed hot air is ejected from the small hole very close to the circuit board. The hot air dries the circuit board efficiently. By applying high-speed airflow to the rotating circuit board, the drying speed of the circuit board is increased. Attached Figure Description

[0020] 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.

[0021] Example: Figures 1-13 As shown, the present invention provides a technical solution for an integrated soldering and dispensing device for inductor pins. The device consists of a reflow oven 1, a circuit board 67, and a dispensing machine 18. The integrated soldering and dispensing device is composed of the dispensing machine 18, a combined flow guiding structure, a one-way valve 62, a water guide connector 63, an exhaust pipe 3, a heat exchange tube 14, and a heat exchange tube 47.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 13An exhaust pipe 2 is fixedly connected between the air outlet of the reflow oven 1 and the exhaust pipe 3. Multiple exhaust pipes 2 discharge the high-temperature exhaust gas generated during the soldering of the inductor pins on the circuit board 67 of the reflow oven 1, ensuring that the volatile organic compounds generated during the heating of the solder paste in the reflow oven 1 are discharged. The exhaust gas enters the exhaust pipe 3 and is guided into the exhaust gas treatment system.

[0023] Heat exchange tube 14 is installed inside exhaust pipe 3. Both ends of heat exchange tube 14 are fixedly connected to guide pipe 5 15 and guide pipe 4 13, respectively. Guide pipe 5 15 and guide pipe 4 13 are both fixedly connected to exhaust pipe 3, ensuring that heat exchange tube 14 remains stably inside exhaust pipe 3. One end of guide pipe 4 13 and guide pipe 5 15 extends to the outside of exhaust pipe 3. A water pump 2 16, fixedly connected to one end of guide pipe 5 15, is fixedly installed outside reflow oven 1. The inlet end of water pump 2 16 is connected to a water supply pipe. After pumping water, water pump 2 16 delivers it to the inside of heat exchange tube 14 through guide pipe 5 15. The water is heated to warm water as it flows inside heat exchange tube 14. The warm water then enters guide pipe 3 12, which is fixedly connected to guide pipe 4 13. A water tank 4 is fixedly connected to the top of the insulated water tank 4. Warm water enters the insulated water tank 4 and is stored for later use. A metal box 8 is rotatably installed on the rear wall of the inner cavity of the sealed box 5, which is fixedly connected to the top of the insulated water tank 4. A water pump 10 is fixedly connected to the rear side of the sealed box 5. The water outlet of the water pump 10 is rotatably connected to the metal box 8. A guide pipe 2 11 is fixedly connected between the water inlet of the water pump 10 and the insulated water tank 4. Therefore, the operation of the water pump 10 is controlled. The water pump 10 draws warm water from the inside of the insulated water tank 4 through the guide pipe 2 11 and delivers the drawn warm water to the inside of the metal box 8. The warm water inside the insulated water tank 4 can be quickly used. The warm water is then used to rinse the circuit board 67, reducing the drastic temperature changes that the circuit board 67 is subjected to during the processing. The warm water is also beneficial for dissolving and rinsing off the adhesive substances on the outside of the circuit board 67.

[0024] A drain valve 7 is fixedly connected to the bottom of one side of the sealed box 5. The drain valve 7 is controlled to open and discharge the wastewater inside the sealed box 5. Electromagnets 68 are fixedly connected to both sides of the top of the inner cavity of the sealed box 5. After the electromagnets 68 are working, they use magnetic force to fix the iron metal box 8, and the metal box 8 is limited and cannot move.

[0025] A fixed bracket 17 is fixedly connected to the top of the sealed box 5. The dispensing machine 18 is fixedly installed inside the fixed bracket 17. The arrangement of the insulated water tank 4, the sealed box 5 and the fixed bracket 17 allows the dispensing machine 18 to be positioned at a high position, providing sufficient working space for the dispensing machine 18 to dispense glue onto the circuit board 67. The sealed box 5 and the robotic arm are respectively located on the rear and front sides of the reflow oven 1. The circuit board 67 is located between the robotic arm and the sealed box 5. The square groove 6 opened on the front side of the sealed box 5 provides a channel for the circuit board 67 to enter the interior of the sealed box 5.

[0026] Specifically, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 In the robotic arm, support frame 19 is fixedly installed at the bottom front side of the reflow oven 1. Support frame 21 is fixedly connected to the output end of the forward / reverse motor 20, which is fixedly connected to the top of support frame 19. Support frame 4 28 is fixedly connected to the piston end of the hydraulic cylinder 26, which is fixedly connected to the top of support frame 21. Controlling the forward / reverse motor 20 controls the rotation of support frame 21, hydraulic cylinder 26, and support frame 4 28, adjusting the orientation of support frame 4 28 on the horizontal plane. A brake 22 is sleeved on the outer side of the output end of the forward / reverse motor 20. The outer side of the brake 22 is connected to the support frame 28. Multiple fixed vertical rods 23 are fixedly connected between the first frame 19. After the first reversing motor 20 finishes working, the control brake 22 is activated to brake the output end of the first reversing motor 20, and the second support frame 21 is braked and limited. Multiple third support frames 24 are fixedly connected to the bottom of the second support frame 21. The bottom of the rolling ball 25 installed at the bottom of the third support frame 24 abuts against the top of the first support frame 19. The multiple third support frames 24 and the multiple rolling balls 25 support the second support frame 21, ensuring the stability of the rotation of the second support frame 21 and sharing the pressure on the first reversing motor 20.

[0027] The hydraulic cylinder 26 is controlled to work and control the up and down position of the support frame 28. Multiple telescopic rods 27 are fixedly connected to the top of the support frame 21. The piston end of the telescopic rods 27 is fixedly connected to the support frame 28. The multiple telescopic rods 27 support and limit the support frame 28, so that the support frame 28 and the support frame 21 can only move relative to each other in the up and down direction. The top of the support frame 28 is slidably connected to the top of the U-shaped frame 29, and a support frame 31 is provided on the top of the support frame 28. Multiple support frames 33 are rotatably mounted on the outside of the transmission shaft 32, which is fixedly connected inside the support frame 31. The support frames 33 are fixedly mounted on the top of the support frame 28, so the support frame 31 can rotate around the transmission shaft 32. Two gears 34 are fixedly mounted on the outside of the transmission shaft 32, and the racks 30 meshing at the bottom of the two gears 34 are fixedly mounted on the top of the U-shaped frame 29. The arrangement of the U-shaped frame 29 allows the two racks 30 to move synchronously. The unit is fixedly connected to a pneumatic cylinder 35 and two support frames 36. A telescopic rod 37 is fixedly connected between the two support frames 36. The piston ends of the pneumatic cylinder 35 and the telescopic rod 37 are fixedly connected to the inner wall of the U-shaped frame 29. Under the action of the pneumatic cylinder 35 and the telescopic rod 37, the U-shaped frame 29 slides horizontally on the top of the support frame 28. Under the action of the two racks 30, the two gears 34 rotate, the transmission shaft 32 rotates, and the support frame 31 rotates. By controlling the extension or retraction of the pneumatic cylinder 35, the support frame 31 can be controlled to tilt.

[0028] A pneumatic cylinder 2 38 and a telescopic rod 39 are fixedly mounted on the support frame 5 31. A fixed frame 2 40 is fixedly connected between the piston ends of the pneumatic cylinder 2 38 and the telescopic rod 3 39. The fixed frame 2 40 is fixedly installed on the outside of the support frame 8 41. By controlling the operation of the pneumatic cylinder 2 38, the relative distance between the support frame 8 41 and the support frame 5 31 is adjusted, and the relative distance between the metal tube 42 and the support frame 5 31 is adjusted. The two diversion containers 60 and the metal tube 42 move synchronously and play the role of clamping and fixing the circuit board 67. Therefore, the robotic arm can control the two diversion containers 60 to move in multiple directions and control the circuit board 67 to move in multiple positions to meet the processing needs of the circuit board 67. It can quickly clamp and transport the circuit board 67, ensuring the continuity of the soldering of the circuit board 67 in the reflow oven 1.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12A telescopic tube 43 is fixedly connected to the end of the metal tube 42 away from the diversion container 60. An air pump 44 is fixedly connected between one end of the telescopic tube 43 and the support frame 31. A hose 45 is fixedly connected to the air inlet end of the air pump 44. A heat exchange tube 47 is located outside the heat exchange tube 14 and inside the exhaust pipe 3. A guide pipe 46 and a guide pipe 48 are fixedly connected to both ends of the heat exchange tube 47. Both the guide pipe 46 and the guide pipe 48 are fixedly installed on the exhaust pipe 3. One end of the guide pipe 46 is fixedly connected to the hose 45. The guide pipe 48 guides the outside gas into the heat exchange tube 47. The gas is heated by the high-temperature exhaust gas inside the exhaust pipe 3 during the flow inside the heat exchange tube 47. The air pump 44 is controlled to work to extract the hot gas inside the heat exchange tube 47 through the hose 45.

[0030] A sliding frame 56 is fixedly installed on the outside of a distribution box 57, which is fixedly connected to one end of a metal pipe 42. The sliding frame 56 is fixedly installed on the outside of the metal pipe 42 and moves synchronously with the distribution box 57 and the metal pipe 42. Two telescopic pipes 58 are fixedly connected to both sides of the distribution box 57. One end of the telescopic pipe 58 is fixedly connected to a one-way valve 59. The two one-way valves 59 on the same side are fixedly connected to the adjacent distribution container 60. The telescopic pipes 58 can extend and retract. The one-way valves 59 are slidably connected to the sliding frame 56, so the distribution container 60 is slidably installed on one side of the sliding frame 56. Multiple small holes 61 are opened on the side of the two distribution containers 60 that are close to each other. The air pump 44 delivers hot air into the distribution container 60 through the telescopic pipe 43, the metal pipe 42, the distribution box 57, the telescopic pipe 58, and the one-way valve 59. The hot air is discharged through the multiple small holes 61.

[0031] The outer wall of the dual-axis pneumatic cylinder 64, which is set between the two diversion containers 60, is fixedly connected to the sliding frame 56. The piston ends of the dual-axis pneumatic cylinder 64 are fixedly connected to the two diversion containers 60 respectively. The top and bottom of the dual-axis pneumatic cylinder 64 are fixedly connected to the limit frame 65. Two sliding plates 66 are fixedly connected to one side of the diversion container 60. The sliding plates 66 slide through the limit frame 65. Under the action of the sliding plates 66 and the limit frame 65, the two diversion containers 60 move relative to each other. The diversion container 60, which plays the role of guiding air, clamps and fixes the circuit board 67.

[0032] A door panel 54 is rotatably connected to one side of the sliding frame 56. An electromagnet 55 is fixedly connected inside the door panel 54, sleeved on the outside of the metal tube 42 and attached to the metal tube 42. When the electromagnet 55 is working, it is attracted and fixed to the iron metal tube 42 by magnetic force. Before the door panel 54 is limited, the door panel 54 and the sliding frame 56 move synchronously.

[0033] The output end of the forward and reverse motor 49, which is rotatably connected inside the support frame 41, is fixedly connected to the rotating shaft 50. Gear 51, which is fixedly installed on the outside of the rotating shaft 50, meshes with gear 52. Gear 52 is fixedly installed on the outside of the metal tube 42 and controls the operation of the forward and reverse motor 49. Under the action of the rotating shaft 50, gear 51, and gear 52, the metal tube 42 rotates. The metal tube 42 drives the sliding frame 56 and the two diversion containers 60 to rotate. A brake 53 is sleeved on the outside of the rotating shaft 50 and is fixedly installed inside the support frame 41. After the forward and reverse motor 49 has finished working, the brake 53 is controlled to work to brake the rotating shaft 50, and the metal tube 42 is braked.

[0034] The working principle of the integrated soldering and dispensing device is as follows: After the reflow oven 1 solders the inductor pins onto the circuit board 67, it transports the circuit board 67 between the robotic arm and the sealed box 5. At this point, the circuit board 67 moves to the bottom of the two flow distribution containers 60. Subsequently, the robotic arm drives the two flow distribution containers 60 to descend, and the two flow distribution containers 60 move to both sides of the circuit board 67. Then, the dual-axis pneumatic cylinder 64 drives the two flow distribution containers 60 to move closer together and clamp and fix the circuit board 67. The robotic arm drives the two flow distribution containers 60 and the clamped and fixed circuit board 67 to move upward. Through the cooperation of the robotic arm, the two circuit boards 67 and the reflow oven 1, the positioning, fixing and displacement of the circuit board 67 after soldering are quickly completed, ensuring the continuous operation of the reflow oven 1 and increasing the speed of soldering the inductor pins onto the circuit board 67.

[0035] The robotic arm controls the two diversion containers 60 and the clamped circuit board 67 to move upwards and into the sealed box 5, so that the two diversion containers 60 and the circuit board 67 enter the sealed box 5 through the square slot 6. After the sliding frame 56 is fully inside the sealed box 5 and the door panel 54 blocks the square slot 6, the water guide connector 2 63, which is fixedly connected to the one-way valve 2 62, moves to the outside of the water guide connector 1 9. After the two water guide connectors 2 63 are fitted onto the outside of the two water guide connectors 1 9, the control electromagnets 2 68 and 1 55 stop working. The system controls the operation of the forward and reverse motor 49. The forward and reverse motor 49 drives the metal tube 42 to rotate through the rotating shaft 50, gear 51, and gear 52. The metal tube 42 drives the sliding frame 56 to rotate. The sliding frame 56 drives the dual-shaft pneumatic cylinder 64 and the two diversion containers 60 to rotate. The circuit board 67, which is clamped and fixed by the two diversion containers 60, rotates. When the circuit board 67 rotates 90°, the forward and reverse motor 49 stops working, and the brake 53 works to brake the rotating shaft 50. The rotating shaft 50 is limited, the metal tube 42 is limited, and the circuit board 67 is limited.

[0036] Then, the water pump 10 is controlled to operate. Water pump 10 draws warm water from the insulated water tank 4 through the guide pipe 21 and delivers it to the metal tank 8. The warm water enters the distribution container 60 through the water guide connector 19, water guide connector 23, and one-way valve 22. Due to the one-way conduction characteristic of the one-way valve 19, the water entering the distribution container 60 cannot enter the telescopic pipe 258. The warm water accumulates inside the distribution container 60 and sprays out from multiple small holes 61. Because the drainage speed of the multiple small holes 61 is less than the water entry speed through the water guide connector 263, the hydraulic pressure inside the distribution container 60 increases, and the flow rate of the water discharged through the small holes 61 increases. Therefore, the two distribution containers 60 spray water onto the circuit board 67 in the middle through the multiple small holes 61 to rinse the circuit board 67. 60. Two one-way valves 62 and four one-way valves 59 form a container based on pressurization and clamping. With the circuit board 67 clamped and fixed in place, the circuit board 67 is rinsed efficiently and quickly. Warm water is used to rinse the circuit board 67, which helps to dissolve and remove the adhesive on the circuit board 67. At this time, the circuit board 67 is facing downwards. After the wastewater generated by rinsing the circuit board 67 loses its power, it falls to the bottom of the inner cavity of the sealed box 5. At this time, the door plate 54, which is rotatably connected to the sliding frame 56, seals the square groove 6, so that the rinsing of the circuit board 67 is carried out in a sealed environment. The cleaning of the circuit board 67 is carried out between the reflow oven 1 and the dispensing machine 18 without affecting the operation of the reflow oven 1 and the dispensing machine 18, ensuring the efficient and stable operation of the soldering and dispensing integrated device.

[0037] After a period of time, water pump 10 stops working. Since some of the small holes 61 are connected to the bottom wall of the inner cavity of the diversion container 60, after a while, the water inside the diversion container 60 is completely discharged through the small holes 61. Then, control brake 3 53 stops working, forward and reverse motor 2 49 works, metal pipe 42 rotates, circuit board 67 rotates, and water on the outside of circuit board 67 is thrown out, accelerating the drying speed of circuit board 67. At the same time, control air pump 44 works to deliver hot air into the diversion container 60 through telescopic pipe 1 43, metal pipe 42, diversion box 57, telescopic pipe 2 58, and one-way valve 1 59. Valve 62 has a unidirectional conduction characteristic, meaning the gas inside the diversion container 60 can only exit through the small hole 61. The air intake velocity inside the diversion container 60 is much greater than the exhaust velocity. High-speed hot air is ejected from the small hole 61, which is very close to the circuit board 67. This hot air efficiently dries the circuit board 67. By applying a high-speed airflow to the rotating circuit board 67, the drying speed of the circuit board 67 is increased. After a period of time, the second forward and reverse motor 49 stops working. During this process, the second forward and reverse motor 49 drives the metal tube 42 and the circuit board 67 to rotate an integer number of revolutions. When the diversion container 60 stops rotating, the second electromagnet 68 is activated. Iron rod 68 adsorbs and fixes metal box 8, causing metal box 8 and water guide connector 9 to return to their initial state. Sliding frame 56 and door panel 54 remain in their initial state. Electromagnet 55 is controlled to work, and electromagnet 55 is adsorbed and fixed to the iron metal tube 42 by magnetic force. Door panel 54 moves synchronously with metal tube 42. At the same time, the robotic arm works to drive the diversion container 60 and circuit board 67 out of the sealed box 5 and move towards the bottom of dispensing machine 18. During this process, air pump 44 is always working. After the diversion container 60 and circuit board 67 leave the sealed box 5, forward and reverse motor 49 starts working again. The drive metal tube 42, two diversion containers 60, and circuit board 67 rotate. Under the action of rotation and hot air, the circuit board 67 is thoroughly dried before moving to the bottom of the dispensing machine 18. The two diversion containers 60, two one-way valves 62, and four one-way valves 59 form a container with pressurization and clamping functions, ensuring that water and hot air act directly on the surface of the circuit board 67 to be dispensed with glue, so as to accurately rinse and dry the circuit board 67, reduce water waste, and make the heat in the exhaust gas discharged from the reflow oven 1 meet the needs of warm water rinsing and hot air drying of the circuit board 67 after heat recovery, thus improving resource efficiency.

[0038] When circuit board 67 moves to the bottom of dispensing machine 18, the second forward and reverse motor 49 stops working. During this operation, the second forward and reverse motor 49 drives the metal tube 42 and circuit board 67 to rotate an integer number of revolutions plus 180°, ensuring the adhesive-depositing surface of circuit board 67 faces upwards. Then, the robotic arm, in coordination with the second forward and reverse motor 49, adjusts the posture of circuit board 67. After adjusting the posture of circuit board 67 to the adhesive-depositing position, the robotic arm moves circuit board 67 to the dispensing port of dispensing machine 18. Dispensing machine 18 completes the adhesive dispensing work on the outer side of the inductor pin solder joint on circuit board 67. Then, the robotic arm controls circuit board 67 to move away from dispensing machine 18 and, again in coordination with the second forward and reverse motor 49, adjusts the posture of circuit board 67, moving it back to the dispensing port of dispensing machine 18. Dispensing machine 18 completes the adhesive dispensing work on the outer side of the inductor pin solder joint on circuit board 67. This process is repeated until the adhesive dispensing work on circuit board 67 is complete.

[0039] Beforehand, a small trolley is placed on one side of the reflow oven 1. The robotic arm then places the 67-block circuit board, which has been processed with epoxy resin, onto the trolley.

[0040] By setting up a waste gas pipe 3, a robotic arm, a combined flow guiding structure, a support frame 41, a metal pipe 42, two flow distribution containers 60, and a forward and reverse motor 49 on the outside of the reflow oven 1, the inductor pins of the circuit board 67 are soldered and glued in one integrated process. This eliminates the need for multiple clamping, transportation, and positioning of the circuit board 67, shortening the processing cycle of the circuit board 67 and increasing the processing speed of the circuit board 67.
