Description

Technical Field

[0001] The utility model mainly relates to the technical field of welding, and specifically relates to a welding device for electronic products that prevents scalding. Background Art

[0002] There is a heating element inside the soldering pen. When powered on, this element quickly heats up and maintains a constant temperature. During the welding process, the operator places the solder at the welding site, and the solder melts when heated, thus connecting the electronic components to the metal points on the circuit board.

[0003] In view of the problem that after the existing soldering gun completes welding, the gun head remains at a high temperature, which may cause the operator to accidentally touch it and get scalded, this new type of soldering gun adopts a special design to prevent such safety accidents. The new type of soldering gun includes a protective sleeve made of heat-insulating material. After the welding operation is completed, the protective layer isolates the soldering gun head from the outside world, thereby reducing the risk of the operator being scalded due to accidentally touching the gun head.

[0004] Such soldering guns may also be equipped with sensors and alarm systems. When the welding operation is completed and the temperature of the soldering gun head drops to a safe range, the system will automatically send a signal to notify the operator. Such a design significantly improves the use safety and reduces the risk of accidental injury during the work process. Content of the Utility Model

[0028] Please refer specifically to the attached Figure 1 、 4 As shown in the figure, in a preferred embodiment of the present utility model, a welding device for electronic products that prevents scalding includes a welding torch housing 10 and an electrode discharge pipe 20 provided on one side of the welding torch housing 10. A welding torch main body 11 is sleeved inside the welding torch housing 10, and an anti-scald protection cavity 12 is provided outside the housing of the welding torch main body 11;

[0029] Inside the anti-scald protection cavity 12, a first gasket 121, a first spring 122, and a protective sleeve 123 are successively arranged from top to bottom. The first gasket 121 is embedded in the top end inside the anti-scald protection cavity 12. The bottom end of the first spring 122 always abuts against the top of the protective sleeve 123. When the first spring 122 is squeezed, the top end of the first spring 122 will abut against the first gasket 121. Symmetrically arranged on the outer wall of the protective sleeve 123 are sliding grooves 133, and limiting grooves 135 are successively arranged at the ends of the sliding grooves 133.

[0030] It should be noted that in this embodiment, when the welding torch housing 10 stops working and the limiting member 13 is pulled up, the first spring 122 will, due to the elastic force given by the compression spring, move the limiting block 131 onto the sliding groove 133, and then the acting force given by the compression spring will move the limiting groove 135 at the other end of the protective sleeve 123 onto the limiting block 131, and the protective sleeve 123 can completely enclose the welding torch head.

[0031] Please refer specifically to the attached Figure 5 As shown, in a preferred embodiment of the present invention, for a welding device for electronic products that prevents scalding, it is characterized in that symmetrically arranged on the outer wall of the welding torch housing 10 are limiting members 13. Inside the limiting members 13, there are a limiting block 131 and a second spring 132, and the second spring 132 is sleeved on the limiting block 131.

[0032] It should be noted that in this embodiment, when the limiting member 13 is pulled up, the limiting block 131 inside it will also be pulled up synchronously, and the second spring 132 will be compressed by the squeezing force, causing the protective sleeve 123 it limits to start moving under the action of the first spring 122.

[0033] Please refer specifically to the attached Figure 2 As shown, in a preferred embodiment of the present invention, for a welding device for electronic products that prevents scalding, it is characterized in that a heat insulation layer 111 is sleeved on the outer wall of the welding torch main body 11, and a temperature monitoring alarm 14 is provided on the welding torch main body 11 and penetrates through the outer wall of the welding torch housing 10.

[0034] It should be noted that in this embodiment, when the welding torch housing 10 starts to operate, the heating component inside starts to heat up to heat the welding head. When the temperature reaches the specified temperature, the temperature monitoring alarm 14 will light up the indicator light and emit an alarm sound.

[0035] Please refer specifically to the attached Figure 3 As shown, in a preferred embodiment of the present invention, a welding rod wiping ring 21 is provided at the tin outlet of the welding rod discharge pipe 20.

[0036] It should be noted that the welding rod is simply wiped by the welding rod wiping ring 21 provided at the tin outlet before being sent out from the welding rod discharge pipe 20, thereby reducing sputtering during welding.

[0037] The specific process of the present utility model is as follows:

[0038] After the present utility model is powered on, all the electrical components of the device are triggered to operate by the PLC.

[0039] When the welding work is completed, the welding gun housing 10 stops working, and the welding gun head of the welding gun body 11 is in a high-temperature state. Pull up the limit member 13, and the limit block 131 inside it will also be pulled up synchronously. The second spring 132 will be compressed by the extrusion force, and the limit block 131 is stretched beyond the blocking plate 134. Its protective sleeve 123 moves downward under the action of the first spring 122 until the limit block 131 is caught in the limit groove 135 at the upper end of the protective sleeve 123.

[0040] The first spring 122 will move the limit block 131 onto the sliding groove 133 due to the elastic force given by the compression spring, and then move the limit groove 135 at the other end of the protective sleeve 123 onto the limit block 131 by the acting force of the compression spring, and the protective sleeve 123 can completely cover the welding head of the welding gun housing 10.

[0041] When the welding gun housing 10 is about to start working, observe the temperature of the gun head displayed by the temperature monitoring alarm 14. When the temperature reaches the safe range, push the protective sleeve 123 into the limit groove 135 at the upper end, pull up the limit member 13, and the limit block 131 inside it will also be pulled up synchronously. The second spring 132 will be compressed by the extrusion force, and the limit block 131 will move on the sliding groove 133 until it reaches the blocking plate 134. Then pull up the limit member 13 again to stretch the limit block 131 beyond the blocking plate 134 and catch it in the limit groove 135 at the bottom of the protective sleeve 123.

[0042] The welding rod discharge pipe 20 connected by the movable connecting rod 30 will also discharge tin synchronously and evenly when the welding gun housing 10 is working. A welding rod wiping ring 21 is provided at the tin outlet of the welding rod discharge pipe 20 to wipe the welding rod to be melted and welded, thereby reducing the risk of welding sputtering.

[0043] The above has made an exemplary description of the present utility model in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as this non-substantive improvement is made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
