DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 6 , a circuit board welding device shown in the figure comprises an electric soldering iron 1, a rubber sleeve 2 is arranged on the outer side of the electric soldering iron 1, and a support frame 3, a support ring 4 is installed on the support frame 3, a docking ring 5 for plugging the electric soldering iron 1 is installed in the support ring 4, a rotating part 6 for rotating the docking ring 5 is fixed on the support frame 3; and a connecting frame 7 installed on the inner wall of the support frame 3, a driving part 8 is fixed on the connecting frame 7, one end of the driving part 8 is docked with the rotating part 6, and the other end is fixed with a driving column 9; and a cleaning component 10 adapted to the driving column 9, a docking part 11 is installed on the outer side of the connecting frame 7, and is connected to the bottom of the cleaning component 10 through the docking part 11;

[0029] In this solution, the designed support frame 3 cooperates with the support ring 4 and the docking ring 5 to assist in the insertion of the soldering iron 1. At the same time, the driving part 8 drives the rotating part 6 to make the soldering iron 1 rotate. The cleaning component 10 can be used to grind the outer end of the soldering iron 1 to effectively remove the material attached to the outer end, thereby improving the tinning effect during subsequent welding.

[0030] For further information, see Figure 1 - Figure 6 The driving part 8 includes a dual-axis motor 12 fixed to the connecting frame 7, one end of the dual-axis motor 12 is fixed with a universal joint 13 through a coupling, and is connected to the rotating part 6 through the universal joint 13, and the other end of the dual-axis motor 12 is fixed to the driving column 9 through a coupling;

[0031] Also, see Figure 2 - Figure 7 The cleaning component 10 includes a driving rod 14 and a transmission rod 15. A connecting rod 16 is fixed to the bottom of the driving rod 14 and the transmission rod 15. A connecting plate 17 is rotatably installed on the two connecting rods 16. A docking frame 18 is fixed to the outer side of the connecting plate 17. The docking frame 18 is provided with a docking port 19 that is compatible with the docking portion 11. A grinding belt 20 is sleeved on the outer side of the driving rod 14 and the transmission rod 15. A socket 21 that is compatible with the driving column 9 is provided at the outer end of the driving rod 14, and the driving rod 14 is driven to rotate by the rotation of the driving column 9.

[0032] In this solution, the driving part 8 drives the cleaning part 10 to clean the outer end of the electric soldering iron 1.

[0033] The personnel first insert the electric soldering iron 1 which has been heated for a period of time into the docking ring 5, and fit the welding end at the bottom of the electric soldering iron 1 with the outer side of the grinding belt 20. Then, the dual-axis motor 12 is rotated to rotate the driving column 9, thereby driving the driving rod 14 to rotate, and driving the grinding belt 20 to start rotating, so as to rub the outer end of the electric soldering iron 1 to remove the debris attached to the outer side of the electric soldering iron 1.

[0034] For further information, see Figure 2 - Figure 7 The rotating part 6 includes a rotating column 25, the bottom of the rotating column 25 is fixed to the universal joint 13, the outer side of the rotating column 25 is in contact with the outer side of the docking ring 5, a limiting block 26 is fixed inside the docking ring 5, and a plurality of limiting openings 27 that are compatible with the limiting block 26 are provided on the outer side of the rubber sleeve 2, and magnetic blocks that are magnetically attracted to each other are provided on the mating surfaces of the docking ring 5 and the rubber sleeve 2.

[0035] In this solution, the principle of using the rotating part 6 to drive the electric soldering iron 1 to rotate is as follows:

[0036] After the electric soldering iron 1 is inserted into the outer side of the docking ring 5, the limit block 26 is engaged with the limit opening 27. At the same time, under the action of the magnetic block, the electric soldering iron 1 can be stably placed in the docking ring 5. Afterwards, the dual-axis motor 12 rotates, driving the universal joint 13 to rotate accordingly, thereby driving the rotating column 25 to rotate, and driving the docking ring 5 fitted therewith to rotate accordingly, thereby driving the electric soldering iron 1 to rotate on its own, and cooperating with the cleaning component 10, thereby achieving the grinding and cleaning of the bottom of the electric soldering iron 1, and effectively removing the residual foreign matter on the outer side of the electric soldering iron 1.

[0037] For further information, see Figure 2 , Figure 7 and Figure 8 The docking portion 11 includes a docking plate 22 fixed to the outside of the connecting frame 7, a rotating rod 23 is rotatably mounted on the bottom of the docking plate 22, and a docking card 24 adapted to the docking port 19 is fixed to the outside of the rotating rod 23;

[0038] In this solution, personnel can disassemble the cleaning component 10. When disassembling, first turn the docking card 24 to make the docking card 24 detach from the docking port 19, and then remove the grinding belt 20 and the driving rod 14, so that the personnel can replace the grinding belt 20.

[0039] After replacing the grinding belt 20, the personnel need to reinstall the cleaning component 10. During installation, the docking card 24 is rotated first, and then the personnel aligns the socket 21 on the drive rod 14 with the drive column 9 and inserts it. Finally, the docking card 24 is rotated into the docking port 19 to limit the position, thereby completing the installation of the cleaning component 10.

[0040] It should be noted that, in order to improve the installation stability of the transmission rod 15 , a plug post 31 is fixed on the connecting frame 7 , and a notch 32 matched with the plug post 31 is formed on the transmission rod 15 .

[0041] In this solution, the adjacent surfaces of the rotating column 25 and the docking ring 5 are frosted surfaces, so that when the rotating column 25 is rotating, it can effectively drive the docking ring 5 to rotate.

[0042] Example 2: Please refer to Figure 7 and Figure 8 This embodiment further explains the first embodiment, and the difference is that a component for cleaning the grinding belt 20 is disclosed.

[0043] Specifically, a scraper 28 is fixed to the outer side of the rotating rod 23 , a spring sheet 29 abutting against the scraper 28 is fixed to the connecting frame 7 , and the outer end of the scraper 28 is in contact with the outer side of the grinding belt 20 .

[0044] In this solution, the scraper 28 is squeezed by the designed spring sheet 29, so that the outer end of the scraper 28 can fit the outer side of the grinding belt 20, so that when the grinding belt 20 is in transmission, foreign matter ground off the outer side can be removed, thereby improving the grinding effect;

[0045] At the same time, a traction rod 30 is fixed on the docking card 24, so that each time the cleaning component 10 is disassembled, the spring sheet 29 is pushed outward by the rotation of the traction rod 30, which is convenient for personnel to disassemble and subsequently assemble the cleaning component 10.

[0046] Example 3: Please refer to Figure 8 This embodiment further illustrates other embodiments, and the difference lies in that a second spring piece 33 is added to make the cleaning component 10 fit the outer end of the electric soldering iron 1 more closely.

[0047] Specifically, the connecting frame 7 is rotatably connected to the inner wall of the supporting frame 3 via a rotating shaft. A spring sheet 233 is fixed to the inner wall of the supporting frame 3 and abuts against the docking plate 22. The designed spring sheet 233 generates elastic force, thereby pushing the docking plate 22 to rotate toward the outside of the electric soldering iron 1, so that the grinding belt 20 is closely attached to the outside of the electric soldering iron 1, thereby improving the grinding effect and facilitating the cleaning of the outside of the electric soldering iron 1.
