[0025] 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.

[0026] like Figures 1-6As shown, a circuit board soldering auxiliary device includes: a soldering iron body 1, a wire 2 is provided at the bottom end of the soldering iron body 1, a protrusion is fixedly provided on the outside of the lower end of the soldering iron body 1, a card 5 is attached to the outside of the lower end of the soldering iron body 1, a slot 8 is provided at the front end of the card 5, a partition 3 is vertically attached to the inside of the slot 8, and a spring 4 is provided on the inside of the partition 3.

[0027] The upper end of the soldering iron body 1 is provided with a soldering tip 6, and an auxiliary structure 7 is sleeved on the outside of the soldering tip 6.

[0028] The rest, since the partition 3 is composed of a ring and vertical and horizontal components, the vertical structure of the partition 3 can be inserted into the slot 8 at the front end of the card 5, and the card 5 is engaged with the protrusion on the outside of the soldering iron body 1. After the soldering iron body 1 is held by the user, the ring component of the partition 3 can block the soldering iron body 1 from the circuit board, and the spring 4 increases the thickness of the partition 3 to increase the strength of the partition 3. The designer can extend the vertical part of the partition 3 to increase the connection between the partition 3 and the card 5.

[0029] This has resulted in the following effects and novel technologies:

[0030] This utility model of a circuit board soldering auxiliary device significantly improves the stability and safety of the soldering iron body 1 through its ingenious design. The circular ring and vertical structure of the spacer 3 allow it to be firmly inserted into the slot 8 at the front end of the card 5 and engages with the protrusion on the outside of the soldering iron body 1, forming a stable support structure. The introduction of the spring 4 increases the thickness and strength of the spacer 3 while providing elastic cushioning, allowing the spacer 3 to maintain its shape under pressure and resist deformation. When the user holds the soldering iron body 1 for soldering operations, the circular ring of the spacer 3 effectively prevents direct contact between the soldering iron body 1 and the circuit board, preventing accidental slippage. If the circuit board is damaged, the connection between the spacer 3 and the card 5 can be strengthened by extending the vertical part of the spacer 3, further improving the stability of the device. Most importantly, in this invention, one end of the card 5 is stuck to the outside of the soldering iron body 1, forming an inclined angle. When the user's hand cannot hold the soldering iron body 1, the spacer 3 can hold against the work surface, preventing the soldering iron body 1 from falling directly onto the work surface, greatly reducing the safety hazards caused by accidental drops during the soldering process. This design not only improves the safety factor of the soldering operation, but also reduces the potential damage to the circuit board caused by the soldering iron body 1 falling, providing a safe and reliable soldering auxiliary tool for the electronics manufacturing industry.

[0031] like Figures 1-6As shown, a circuit board soldering auxiliary device includes an auxiliary structure 7 comprising a sleeve 71, a shading leaf 72, a head cover 73, and a support 74. The sleeve 71 is fitted over the outside of the soldering head 6. A petal-shaped shading leaf 72 is arranged in a ring around the upper end of the sleeve 71. An L-shaped support 74 is arranged at the top of the shading leaf 72. The head cover 73 is fixedly mounted at one end of the support 74. The diameter of the sleeve 71 is larger than the diameter of the head cover 73.

[0032] The rest are as follows: the sleeve 71 is fitted over the middle and lower parts of the soldering head 6, the head cover 73 is fitted over the upper part of the soldering head 6, and the head cover 73 exposes the head of the soldering head 6. At the same time, the bracket 74 outside the head cover 73 is connected to the smoke shield 72. The smoke shield 72 can block some of the smoke generated when the head of the soldering head 6 is soldered. The designer can increase the area of ​​the smoke shield 72 to increase the area of ​​the smoke shield 72.

[0033] This has resulted in the following effects and novel technologies:

[0034] This utility model's circuit board soldering auxiliary device effectively improves the comfort and safety of soldering operations through the innovative design of a sleeve 71, a shading leaf 72, a head cover 73, and a support 74. The sleeve 71 is fitted over the middle and lower ends of the soldering tip 6, while the head cover 73 is fitted over the upper end of the soldering tip 6, exposing its head. Simultaneously, the support 74 outside the head cover 73 is connected to the petal-shaped shading leaf 72. The shading leaf 72 can block some of the fumes generated during soldering; by increasing the area of ​​the shading leaf 72, the fume-blocking effect can be further enhanced. This design not only reduces the impact of soldering fumes on the operator but also, due to the isolation effect of the head cover 73 and the sleeve 71, reduces the heat transfer from the surface of the soldering tip 6, preventing accidental burns to the operator. Furthermore, the head cover 73 ensures that the soldering tip 6 does not directly contact the circuit board during soldering, preventing damage to the circuit board due to high temperatures and improving soldering quality and safety. Overall, this utility model provides a more user-friendly and efficient auxiliary tool for electronic soldering.

[0035] Working principle: When using this circuit board soldering auxiliary device, first connect the wire 2 to the external power supply. After the soldering iron body 1 is powered on, the soldering tip 6 starts to work. Then, the sleeve 71 and the head cover 73 are put on the outside of the soldering tip 6. The bracket 74 on the outside of the head cover 73 is connected to the leaf 72. The leaf 72 can prevent the outside of the soldering tip 6 from contacting the circuit board. At this time, the head cover 73 only exposes the head of the soldering tip 6 for use. When the user holds the soldering iron body 1 for use, the user will put the card 5 on the protrusion on the outside of the soldering iron body 1 and insert the combination of the spacer 3 and the spring 4 into the slot 8 on the surface of the card 5. This ensures that the user always keeps a certain distance from the circuit board when holding the soldering iron body 1 for use. This is the working principle of the circuit board soldering auxiliary device.
