Specifically, the soldering iron core 3 is cylindrical, and the length direction of the soldering iron core is parallel to the length direction of the shell 1; a fastening screw extending through housing 1, tip 3 and tip 2 provides a secure connection between tip 3 and housing 1 and between tip 2 and tip 3. The electric welding device for electronic processing further comprises a power line, wherein the power line penetrates through the second end of the shell 1 and is connected with the soldering iron core 3 so as to supply power to the soldering iron core 3.

According to the scheme, when in use, the soldering iron head 2 is inserted into the soldering iron core 3; a length of solder wire is cut and inserted into the shaping tube 13 from the second end of the housing 1 and through the shaping tube 13 and the second receiving chamber 12 and out of the first end of the housing 1 through the discharge opening 121, thereby placing the solder wire on the electro-processing soldering device.

Therefore, the user can operate the electric welding device for electronic processing to weld by only one hand.

Further, the portion of the soldering tip 2 extending out of the housing 1 is bent in a direction close to the tap hole 121.

Specifically, because the solder wire has higher plasticity, after passing through the shaping pipe 13, the solder wire that stretches out from discharge opening 121 is relatively straight, makes soldering bit 2 crooked towards the direction that is close to discharge opening 121, and the solder wire that can conveniently stretch out contacts with soldering bit 2.

Furthermore, the electric welding device for electronic processing also comprises a clamping jaw 4, wherein the clamping jaw 4 is U-shaped, and the middle part of the clamping jaw is provided with a threading hole 41; the length direction of the clamping jaw 4 is parallel to the length direction of the second accommodating cavity 12, a sliding groove 122 parallel to the length direction of the clamping jaw is formed in the side wall of the second accommodating cavity 12, and a convex block 42 matched with the sliding groove 122 is arranged on the side edge of the clamping jaw 4; an inclined surface 124 is arranged in the second accommodating cavity 12, so that the width of one end, close to the discharge hole 121, of the second accommodating cavity 12 is smaller than that of the other end; the clamping jaw 4 is slid, so that the two ends of the clamping jaw 4 can be close to or far away from each other.

Further, the electric welding device for electronic processing further comprises a sliding block 44, a through hole 123 parallel to the length direction of the sliding block is further arranged on the shell 1, and the sliding block 44 can penetrate through the through hole 123 to extend into the second accommodating cavity 12 and be fixedly connected with the clamping jaw 4.

Specifically, the jaw 4 is preferably made of a rubber material having a certain strength and elasticity. The two ends of the jaw 4 are bent towards each other so that, when the jaw 4 is slid, the two sides of the jaw 4 abut against the inclined surfaces 124 in the second receiving chamber 12. The middle part of the clamping jaw 4 is arranged close to the first end of the shaping tube 13. When the solder wire is inserted into the electric soldering device for electronic processing, the solder wire sequentially passes through the shaping tube 13, the threading hole 41 and the discharge hole 121, and then the solder wire is arranged in the middle of the clamping jaw 4, and the solder wire can be clamped when the two ends of the clamping jaw 4 are close to each other. The slider 44 is spaced from the housing 1 and the slider 44 is connected to the side of the clamping jaw 4 remote from the projection 42.

When in use, the solder wires sequentially pass through the shaping tube 13, the threading hole 41 and the discharging hole 121; the sliding block 44 is pressed, meanwhile, the sliding block 44 is pushed towards the direction close to the discharging hole 121, and the clamping jaw 4 is driven to slide by the sliding block 44; in the sliding process, the two side faces of the clamping jaw 4 are subjected to extrusion forces from the inclined face 124 and the sliding block 44, so that the two ends of the clamping jaw 4 are close to each other, and finally the solder wire is clamped and driven to slide and outwards extend from the discharge hole 121.

Furthermore, the surfaces of the two ends of the clamping jaw 4 close to each other are fixedly connected with cushion blocks 43. The cushion block 43 is preferably made of rubber with good softness and elasticity, and a concave cylindrical arc surface with an axis parallel to the length direction of the clamping jaw 4 is arranged on one side of the cushion block 43 close to the solder wire.

The plasticity of the solder wire is very strong, and the clamping jaw 4 needs to have certain intensity, can't select for use too soft material. In order to prevent that clamping jaw 4 from flattening the solder wire when 4 centre gripping solder wires of clamping jaw, the solder wire of being not convenient for stretches out from discharge opening 121, so set up the more soft cushion 43 of material on the face of clamping jaw 4 with the solder wire contact, and still be equipped with sunken cylinder cambered surface on the cushion 43, the shape of further protection solder wire, and simultaneously, cushion 43 receives the extrusion and warp, can more laminate with the solder wire surface, has increased frictional force.

Further, this electric welding device for electronic machining still includes elastic component 5, and elastic component 5 one end is connected the clamping jaw 4 middle part, and the other end is connected on the end wall of keeping away from discharge opening 121 in second accommodation chamber 12.

Specifically, the elastic member 5 is preferably an extension spring. When the elastic piece 5 is in a relaxed state, the clamping jaw 4 is positioned at one end away from the discharge hole in the second accommodating cavity 12. Since the stroke of the sliding groove 122 is fixed, after the solder wire is extended by a certain length by the clamping jaw 4, the clamping jaw 4 needs to be retracted to clamp and pull out the solder wire at the rear section.

When the clamping jaw 4 slides towards the direction close to the discharging hole 121, the spring is in a stretching state; at this time, the sliding block 44 is loosened, and the two ends of the clamping jaw 4 are far away from each other, so that the clamping force on the solder wire is reduced; the clamping jaw 4 slides towards the direction far away from the discharging hole under the action of the elastic force of the elastic piece 5, so that the sliding block 44 can slide next time to stretch out the solder wire.

Further, the rotating shafts of the shaping pipe 13, the discharging hole 121 and the threading hole 41 are positioned on the same straight line; the radius of the shaping tube 13 is larger at one end away from the second accommodating chamber 12 than at the other end.

Specifically, the inner diameter of the discharging hole 121, the inner diameter of the threading hole 41 and the diameter of the end of the shaping tube 13 close to the clamping jaw 4 are equal to the diameter of the solder wire. The plasticity of the solder wire is higher, and under the ordinary condition, the solder wire form is comparatively distorted, and is not convenient for use, so the arrangement pipe 13 has been set up. The solder wire is inserted from the end with the larger diameter of the shaping tube 13 and extends out from the end with the smaller diameter, which is beneficial to adjusting the original twisted shape. The thread hole 41 in the middle of the clamping jaw 4 and the discharge hole 121 on the shell 1 can further limit the shape of the solder wire.

Furthermore, the electric welding device for electronic processing also comprises a temperature sensor 6 and a plurality of luminous bodies 7, wherein the temperature sensor 6 is fixedly arranged in the first accommodating cavity 11 and is close to the soldering iron core 3; the plurality of luminous bodies 7 are fixedly arranged on the shell 1 and are arranged close to the second end of the shell 1, and the temperature sensor 6 can be electrically connected with the plurality of luminous bodies 7.

The luminous bodies 7 are three, and the three luminous bodies 7 are arranged along the length direction of the shell 1 and can emit light with different colors, namely green, yellow and red.

When the electric soldering apparatus for electronic machining is energized, the temperature sensor 6 will monitor the temperature of the solder core 3 in real time. When the temperature sensor 6 monitors that the temperature of the soldering iron core 3 is not more than 70 ℃, an electric signal is sent to the green luminous body 7 to enable the green luminous body to emit light, and the current temperature is not enough to scald a human body; when the temperature sensor 6 monitors that the temperature of the soldering iron core 3 is higher than 70 ℃ and lower than 183 ℃, an electric signal is sent to the yellow luminous body 7 to enable the yellow luminous body to emit light, and the current temperature indicates that the current temperature is enough to scald a human body but the soldering tin wire cannot be melted; when the temperature sensor 6 detects that the temperature of the soldering iron core 3 is higher than 183 ℃, an electric signal is sent to the red luminous body 7 to enable the red luminous body to emit light, and the current temperature is enough to fuse the solder wires.
