In this automatic soldering device for circuit boards, when the heating tube rises or falls, it drives the first rack and the soldering nozzle to move up and down. Then, through the second gear, the third gear, the fourth gear, and the second rack, the tin tube is driven to move up and down. And the moving speed of the tin tube is greater than that of the heating tube.

[0022] During use, the driving method and control method of the conveyor line 1 in this device are both mature existing technologies and will not be elaborated in this article. The point positions of the manipulator 2 are adjusted according to the on-site implementation situation to ensure the accurate implementation of this device during the soldering process. The adjusting machine 4 fixedly arranged on the conveyor line 1 is used to horizontally adjust the position of the transportation mechanism, so that the manipulator 2 drives the soldering mechanism to perform accurate soldering work on the circuit board. Visual sensors 3 are arranged on both sides of the manipulator 2 to perform visual inspection on the soldered circuit board. Specifically, it detects quality problems such as false soldering and voids generated by soldering at the solder joints. The more specific image processing method is completed through a computer program. The computer program described here is a mature existing technology and will not be elaborated in this article. The soldering mechanism fixedly connected to the manipulator 2 is used to complete the soldering work on the circuit board. It is controlled by the manipulator 2 to achieve point-to-point soldering work. The plurality of hot-melt rods 752 and solder strips 773 on the soldering mechanism are used to perform soldering work on the welding points on the circuit board. The welding points and solder joints both refer to the connection point positions between the pins of electronic components and the circuit board. In addition, whether the hot-melt rods 752 and solder strips 773 in this device perform soldering work is achieved through the control of the limiting component, that is, the hot-melt rods 752 and solder strips 773 corresponding to the non-soldering points do not work and do not contact the circuit board. The multiple transport mechanisms provided on the conveyor line 1 are used to transport the circuit boards. Before soldering the circuit boards, the carrier 6 and the circuit board on the carrier 6 can be easily located by the manipulator 2 at the soldering points. Moreover, the transport mechanisms on this equipment can stably control the electronic components to be soldered during the soldering process of the circuit board, facilitating the connection between the electronic components and the circuit board; The vision sensor 3 is used to visually inspect the soldered circuit board. Specifically, it detects quality problems such as false soldering and voids generated by soldering at the solder joints; In this embodiment, the soldering seat 7 provided on the manipulator 2 is used to install soldering components in this equipment such as the hot melt rod 752 and the solder bar 773. The pre-installation grooves 72 evenly opened on the inner side of the soldering seat 7 are used to load the loading pipe fittings 75. The insertion holes 74 opened on the inner side of the pre-installation grooves 72 are used to allow the loading pipe fittings 75 to extend to the outside of the soldering seat 7. The loading pipe fittings 75 provided on the inner side of the pre-installation grooves 72 are used to load and fix the heater 751. The isolation pipe 753 fixedly connected to the bottom of the loading pipe fitting 75 is used to separate the soldering seat 7 from the hot melt rod 752, reducing the possibility of damage to the hot melt rod 752 and preventing the hot melt rod 752 from burning the soldering seat 7 at high temperature; After the hot melt rod 752 melts the solder bar 773, the tin integrating assembly sleeved at the bottom of the isolation pipe 753 can integrate the melted solder bar 773, that is, limit the melting range of the solder bar 773, so that the contact area between the melted solder bar 773 and the pins of the electronic components can be increased, thereby improving the soldering quality of the electronic components on the circuit board; The limit assembly fixedly provided on the inner side of the pre-installation groove 72 is used to control the vertical displacement distance of the loading pipe fitting 75. It can drive the hot melt rod 752 and the solder bar 773 to perform soldering or not. The limit assembly is connected to the loading pipe fitting 75 to achieve a common linear displacement; The hollow connecting ring 7532 sleeved on the isolation tube 753 is used for hermetically connecting the outer high-temperature resistant shell 7531 and the inner high-temperature resistant cloth sleeve 7534, and can convey air. The hollow connecting ring 7532 and the outer high-temperature resistant shell 7531 fixedly connected to its bottom are made of hard materials. When the sealed cavity formed by hermetically connecting between the outer high-temperature resistant shell 7531 and the inner high-temperature resistant cloth sleeve 7534 is inflated, the hollow connecting ring 7532 and the outer high-temperature resistant shell 7531 may not deform, while the inner high-temperature resistant cloth sleeve 7534 hermetically connected to the bottom of the hollow connecting ring 7532 and located inside the outer high-temperature resistant shell 7531 will deform according to the volume of air filled in the sealed cavity, expanding and deforming, which can limit the melted tin bar 773, making it converge at the soldering point. The multiple first flow tubes 7533 provided on the hollow connecting ring 7532 are used to convey the air inside the hollow connecting ring 7532 to the inside of the sealed cavity. The isolation cloth ring 7535 fixedly provided on the inner side of the sealed cavity is used to divide the sealed cavity into two sections, namely the upper cavity and the lower cavity. The upper cavity is filled with gas first, and at this time, the end cover 734 expands rapidly, so that the end cover 734 first generates a downward thrust on the melted tin bar 773. And because the overall shape of the whole tin assembly is a through frustum shape, this downward thrust generates an inclined thrust, which will strengthen the contact degree between the melted tin bar 773 and the pins of the electronic components, thereby improving the soldering quality. Through the multiple flow retardation units fixedly provided at the bottom of the isolation cloth ring 7535, the air inlet speed of the lower cavity can be slowed down, so that the loading pipe fitting 754 of the lower cavity generates a thrust to wrap the melted tin bar 773 inward (towards the point), so that the melted tin bar 773, under the action of the above three thrusts, makes the fused tin bar 773 in close contact with the pins of the electronic components, thereby significantly improving the soldering quality; The transportation mechanism includes a carrier seat 6 provided on the conveyor line 1 for loading the circuit board and the electronic components to be connected, and can make the two achieve stable connection for the soldering work of the two. The top bag 64 fixedly provided inside the carrier seat 6 realizes the stable insertion of the electronic components on the circuit board by inflating it. The multiple limiting cloth tubes 641 uniformly provided on the top bag 64 are used to connect the top surface and the bottom surface inside the top bag 64, so as to ensure that the overall shape is uniform after inflation. The ventilation holes 642 opened on the limiting cloth tubes 641 are used for inflation inside the limiting cloth tubes 641. The sealing cloth ring 643 provided at the top of the limiting cloth tubes 641 is used to load the sealing cloth balls 644, and when the inside of the limiting cloth tubes 641 is filled with air, the sealing cloth balls 644 will be lifted. The multiple lifted sealing cloth balls 644 can play an anti-slip role for the electronic components to ensure the normal progress of the soldering work; In this device, the air suction and ejection of the top material bag 64 and the internal inflation of the hollow connection ring 7532 are respectively carried out by an air pump. The air pump and the air pipes used to connect this device, especially regarding the solder tinning mechanism, there are multiple air pipes corresponding to each other. Solenoid valves for individually controlling the ventilation of the air pipes and encoders capable of individually controlling the solenoid valves are also provided on the air pipes.

[0033] During use, the clamping groove 61 formed at the inner bottom of the bearing seat 6 of the transportation mechanism is used to load the clamping strip 62. The clamping strip 62 arranged inside the clamping groove 61 is used to clamp and release the bottom of the top feeding bag 64 under the rotation of the plug 621. After clamping, the bottom surface of the top feeding bag 64 is attached to the inner bottom of the bearing seat 6.

[0034] Further, as Figures 15 to 19 shown in the figure, a material placing groove 63 is formed at the inner top of the bearing seat 6. A pressing frame 631 is arranged inside the material placing groove 63. A limiting sliding groove 632 is formed in the pressing frame 631. A clamping buckle 633 is fixedly arranged on the outer side of the bearing seat 6, and the clamping buckle 633 is adapted to the limiting sliding groove 632.

[0035] During use, the material placing groove 63 formed at the inner top of the bearing seat 6 is used to place the circuit board. In the process of placing the circuit board in this equipment, the electronic components to be soldered are first placed upside down, and then the circuit board is inverted inside the material placing groove 63, and the pins of the electronic components are inserted into the corresponding positions on the circuit board. The pressing frame 631 arranged inside the material placing groove 63 is used to press the circuit board, and after the top feeding bag 64 is inflated, the two cooperate to fix the circuit board with the electronic components placed. The clamping buckle 633 fixedly arranged on the outer side of the bearing seat 6 is used to hold the pressing frame 631 to ensure stability.

[0036] Further, as Figures 4 to 19As shown in the figure, a fixing block 776 is fixedly installed at the bottom of the solder seat 7 and near the installation hole 77. A displacement limiting post 777 is fixedly installed on the fixing block 776. A solder feeding pipe 774 is fixedly arranged at the bottom of the solder bar feeder 771. A displacement slot 775 is formed on the solder feeding pipe 774. The displacement limiting post 777 is slidably connected to the inner side of the displacement slot 775. The solder feeding pipe 774 corresponds to the reserved hole 7541. During use, the fixing block 776 fixedly installed at the bottom of the solder seat 7 and near the installation hole 77 is used to load the displacement limiting post 777. The displacement limiting post 777 fixedly installed on the fixing block 776 slides inside the displacement slot 775. The solder feeding pipe 774 fixedly arranged at the bottom of the solder bar feeder 771 is used to convey the solder bar 773. The displacement slot 775 formed on the solder feeding pipe 774 is used to cooperate with the displacement limiting post 777 to control the offset of the solder feeding pipe 774 together. Specifically, when the solder feeding pipe 774 moves vertically downward along with the solder bar feeder 771, it will drive the solder feeding pipe 774 to move together. At this time, when the displacement limiting post 777 slides to the bottom of the displacement slot 775, due to its inclined setting, an outward pulling force will be generated on the solder feeding pipe 774, so that the solder feeding pipe 774 drives the solder bar 773 to disengage from the whole tinning assembly.
