Description

Technical Field

[0001] This utility model relates to a soldering gun, and more particularly to a portable soldering machine. Background Technology

[0002] Soldering is a common task in the operation and maintenance of secondary equipment in hydropower stations. The typical method involves melting the solder with a soldering iron, then using a soldering tip to contact the solder joint, and finally waiting for the joint to cool and complete the soldering. This method requires a high level of operator skill and can easily lead to skin burns and soldering tip clogging. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a convenient soldering machine that simplifies operation and improves soldering safety.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A portable soldering machine includes a housing, within which a solder strip conveying mechanism and a solder liquid pushing mechanism are arranged;

[0006] The solder strip conveying mechanism includes an upper clamping roller and a lower clamping roller, which clamp the solder strip; one end of the solder strip extends into the heating chamber, and the other end of the solder strip is wound around the solder strip reel;

[0007] The molten solder pushing mechanism includes a drive rod, the front end of which is connected to a push head via a guide rod. The push head extends into the molten solder tube, the upper end of which is connected to the heating chamber and the front end of which is connected to the soldering tip. The rear end of the drive rod is connected to a spring on the housing.

[0008] A linkage mechanism is provided between the solder strip conveying mechanism and the solder liquid pushing mechanism. The linkage mechanism includes a flywheel that is rotatably mounted below the drive rod. The flywheel is hinged to the drive rod through a connecting rod to form a crank-slider mechanism. The flywheel and the pressure wheel are connected by a synchronous belt conveying mechanism.

[0009] A bracket is installed on the outside of the housing. The bracket has through holes. The solder strip passes through the bracket via a rotating shaft and is screwed into nuts at both ends for positioning.

[0010] The guide rod slides into the guide hole inside the housing.

[0011] The end of the drive rod is connected to an operating lever, which freely passes through the housing and is connected to the handle.

[0012] The synchronous belt conveyor mechanism includes a first synchronous pulley coaxially mounted with the lower pressure wheel, a second synchronous pulley coaxially mounted with the flywheel, and a synchronous belt installed between the first and second synchronous pulleys.

[0013] A guide plate is fixed inside the housing and on one side of the lower clamping wheel, and the guide plate guides the solder strip.

[0014] The heating chamber is equipped with a heating element that melts the tin strip.

[0015] This utility model provides a convenient soldering machine, which has the following technical effects:

[0016] 1) This device can melt the solder strip inside the device and push it out directly, ensuring safety and preventing skin injury.

[0017] 2) This device, by setting up a crank-slider mechanism and a synchronous belt conveyor mechanism, can simultaneously melt the solder strip during the soldering process of pressing the handle, that is, realize the linkage operation of solder strip conveying and solder liquid pushing, making the soldering operation simpler and reducing the difficulty of operation.

[0018] 3) The prior art document "Liquid Extrusion Solder Gun" with application number "201110255274.1" uses a gear and rack structure for propulsion, which can also achieve pushing; however, in that device, when the rack moves to the left, the solder wire moves to the right, which cannot achieve the simultaneous movement of the solder strip to the left when the rack moves to the left in this device, thus realizing simultaneous soldering and solder wire melting; moreover, the prior art document uses solder wire, which has a fixed length and cannot be continuously fed; this application uses solder strip reels and solder strips, which can supply materials for a long time without repeated feeding. The prior art document uses solder wire, which is cylindrical. When the diameter is large, melting is slow, and when the diameter is small, the liquid supply is insufficient; this application uses solder strip, which is thin and can ensure rapid melting and sufficient solder supply when conveying the same length.

[0023] like Figure 1-2 As shown, a portable soldering machine includes a housing 1. A solder strip conveying mechanism 2 is arranged in the upper part of the housing 1, and a solder liquid pushing mechanism 3 is arranged in the lower part of the housing 1. The solder strip conveying mechanism 2 includes an upper clamping roller 2.1 and a lower clamping roller 2.2, which clamp the solder strip 2.3. Both ends of the solder strip 2.3 pass through the slots 2.4 on the housing 1. One end of the solder strip 2.3 extends into the heating chamber 2.5, and the other end of the solder strip 2.3 is wrapped around a solder strip reel 2.6. The solder strip reel 2.6 is detachably mounted on a bracket 2.7 at the tail of the housing 1.

[0024] A heating element is installed in the heating chamber 2.5. The heating element is a heating resistance wire, which can be connected to an external power source through a control circuit to heat the solder strip 2.3 into a liquid state. A switch button is provided on the housing 1 to control the opening and closing of the heating circuit, facilitating the start or stop of heating. The heating chamber 2.5 is insulated by a high-temperature resistant heat-insulating material lining (not shown in the schematic diagram).

[0025] The bracket 2.7 has a through hole, and the solder strip 2.6 passes through the through hole through a rotating shaft. The two ends of the rotating shaft are screwed in and limited by nuts to ensure that the solder strip 2.6 can rotate to release and convey solder strip. At the same time, the nuts limit the solder strip 2.6 to ensure that it can be disassembled for easy replacement after use.

[0026] The molten solder pushing mechanism 3 includes a drive rod 3.1, the front end of which is connected to a guide rod 3.2. The guide rod 3.2 is slidably engaged with a guide hole 3.3 inside the housing 1. A push head 3.6 is connected to the guide rod 3.2 near the soldering nozzle 3.5. The push head 3.6 extends into the molten solder tube 3.4, and the end of the molten solder tube 3.4 is provided with a soldering nozzle 3.5, which has a fine tip. The push head 3.6 is made of high-temperature resistant heat-insulating material and can push the molten solder in the molten solder tube 3.4 out of the soldering nozzle 3.5.

[0027] The end of the drive rod 3.1 is connected to the operating rod 3.7, which freely passes through the housing 1 and is connected to the handle 3.9. A spring 3.8 is fitted on the operating rod 3.7, with one end connected to the drive rod 3.1 and the other end connected to the end face of the housing 1.

[0028] When the handle 3.9 is pressed to the left, the drive rod 3.1, guide rod 3.2, and push head 3.6 move to the left, which can push out the molten solder in the molten solder tube 3.4. At this time, the spring 3.8 is stretched. After releasing the handle, under the contraction action of the spring 3.8, the spring 3.8 drives the drive rod 3.1, guide rod 3.2, and push head 3.6 to move to the right to reset.

[0029] like Figures 1-2As shown, to achieve continuous conveying of solder strip 2.3, a linkage mechanism 4 is provided between the solder strip conveying mechanism 2 and the solder liquid pushing mechanism 3. The linkage mechanism 4 includes a first synchronous pulley 4.1 coaxially mounted with the lower pressing wheel 2.2, a flywheel 4.2 mounted below the drive rod 3.1, and a connecting rod 4.5 hinged to the flywheel 4.2 at an off-center position. The other end of the connecting rod 4.5 is hinged to the drive rod 3.1. The flywheel 4.2, the connecting rod 4.5, and the drive rod 3.1 constitute a crank-slider mechanism. At the same time, a second synchronous pulley 4.3 is coaxially mounted on the flywheel 4.2, and a synchronous belt 4.4 is installed between the first synchronous pulley 4.1 and the second synchronous pulley 4.3.

[0030] like Figure 1 As shown, when the drive rod 3.1 moves to the left, the flywheel 4.2 rotates counterclockwise, which drives the lower clamping wheel 2.2 to rotate counterclockwise via the synchronous belt transmission mechanism, thereby driving the solder strip 2.3 to be conveyed to the left. During the reciprocating motion of the drive rod 3.1, the flywheel 4.2 rotates counterclockwise, which in turn drives the lower clamping wheel 2.2 to rotate counterclockwise.

[0031] Preferably, a guide plate 2.8 is provided at the slot 2.4 on the right side of the housing 1. The guide plate 2.8 is located between the lower pressing roller 2.2 and the slot 2.4, and can provide horizontal guidance when the solder strip 2.3 enters the housing 1 but does not reach the upper pressing roller 2.1 or the lower pressing roller 2.2.

[0032] Working Principle and Process: Initially, the solder strip 2.3 is passed through the slot 2.4 on the right side of the housing 1. When the solder strip 2.3 is pressed against the gap between the upper clamping roller 2.1 and the lower clamping roller 2.2, pressing the handle 3.9 activates the linkage mechanism 4, driving the lower clamping roller 2.2 to rotate counterclockwise. This clamps the solder strip 2.3 and conveys it forward until it reaches the front end of the heating chamber 2.5. Then, the plug at the rear of the device is connected to an external power source, and the switch button is pressed to initiate heating. After the solder strip 2.3 melts, it enters the molten solder tube 3.4. Pressing the handle 3.9 to the left continues to push the solder strip 2.3 forward for further melting. The drive rod 3.1 moves to the left, driving the push head 3.6 to eject the molten solder from the soldering nozzle 3.5 for soldering.
