[0001] This application relates to the technical field of soldering, and in particular to a semi-automatic soldering machine. Background Technology

[0002] In the field of electronics manufacturing and repair, soldering is a fundamental and crucial process, its quality directly determining the reliability of circuit connections and the final performance of products. Soldering machines are core equipment in the electronics manufacturing industry used to achieve electrical connections between electronic components and substrates such as printed circuit boards (PCBs). They melt solder wire by heating the soldering iron tip, forming a reliable metallurgical bond at the solder joint. Soldering machines are widely used in the assembly processes of various electronic products, including consumer electronics, automotive electronics, and industrial control systems.

[0003] Existing semi-automatic soldering machines typically use a three-axis simple robotic arm for soldering. However, traditional simple robotic arms often use synchronous belt drives or ordinary lead screw structures, which have poor positioning accuracy and are difficult to match the alignment requirements of micro solder joints, easily leading to defects such as solder misalignment and bridging. Utility Model Content

[0004] The purpose of this application is to provide a semi-automatic soldering machine that solves the problems of poor positioning accuracy, difficulty in matching the alignment requirements of micro solder joints, and easy occurrence of solder misalignment, bridging, and other defects that are usually achieved by using a simple three-axis robotic arm for soldering in semi-automatic soldering machines.

By adopting the above technical solution, when the device is in use, the first moving block can slide outside the first slide rail by rotating the first lead screw, so as to achieve stable sliding of the soldering iron tip in the Y-axis direction; the second moving block can slide outside the second slide rail by rotating the second lead screw, so as to achieve stable sliding of the soldering iron tip in the Z-axis direction; and the third moving block can slide outside the third slide rail by rotating the third lead screw, so as to achieve stable sliding of the soldering iron tip in the X-axis direction. This solves the problem that semi-automatic soldering machines usually use a three-axis simple robotic arm for soldering, which has poor positioning accuracy, is difficult to match the alignment requirements of micro solder joints, and is prone to defects such as solder misalignment and bridging.

By adopting the above technical solution, the slide rail provides stable guidance for the moving block, effectively limiting movement deviation, further improving the stability and positioning accuracy of the three-axis motion, and avoiding solder deviation.

This solves the problem of the commonly used three-way sliding mechanism in semi-automatic soldering machines. The simple robotic arm used for soldering has poor positioning accuracy, making it difficult to match the alignment requirements of micro solder joints and easily leading to defects such as solder misalignment and bridging. By setting up a fixed frame, fixed plate, and suction tube, the device can be connected to an external suction device through a flexible tube at one end of the suction tube during use. This allows the suction tube to generate suction force to extract the odor generated by soldering, optimizing the working environment. With the setting of pins, threaded rods, and clamping plates, when changing the template body, the device only needs to insert the pin into the hole inside the clamping mold to initially position the clamping mold and clamping plate. Then, simply rotate the threaded rod to fix the clamping plate and clamping mold, simplifying the changeover operation, improving the versatility and changeover efficiency of the equipment, and increasing work efficiency.

This semi-automatic soldering machine, through the arrangement of a first conveying pipe, a second conveying pipe, conveying wheels, gears, a fourth motor, a support frame, a receiving trough, and a movable rod, allows the position of the solder wire to be fixed by the movable rod during use. The first and second conveying pipes can limit the movement path of the solder wire, ensuring that the solder wire reaches the soldering iron tip and is melted by the tip. The fourth motor can rotate one of the conveying wheels, and through two gears, it can rotate the other conveying wheel in the opposite direction, thereby stably conveying the solder wire and ensuring the uniformity of the solder wire conveying speed and dosage.

[0020] The implementation principle of this application embodiment is as follows: In use, the shape of the clamping mold 35 is adjusted according to the requirements of the workpiece. During adjustment, the clamping plate 32 is first fixed by the clamping jaw cylinder 31. At this time, the pin 33 on the side of the clamping plate 32 is inserted into the corresponding hole of the clamping mold 35 to achieve initial positioning. Then, the threaded rod 34 is rotated to tighten it with the threaded hole of the clamping mold 35, completing the precise clamping of the workpiece. After that, the movable rod 30 can be taken out, passed through the middle hole of the solder wire spool, and then placed into the storage slot. Inside the 29, the movable rod 30 is fixed to secure the solder wire spool. The solder wire from the spool is then passed through the first delivery pipe 22 and the second delivery pipe 23, positioning it on the side of the soldering iron tip 18. The workpiece can then be clamped and fixed by the gripper cylinder 31 and the clamping mold 35. Once the workpiece is secured and soldering is in progress, the first motor 5 is activated. The output shaft of the first motor 5 rotates the first lead screw 3. The rotation of the lead screw 3 causes the first moving block 4 to slide along the first slide rail 6, thus moving the soldering iron tip 18 in the Y-axis direction. The second motor 10 is started, and its output shaft rotates the second lead screw 8. The rotation of the lead screw 8 causes the second moving block 9 to slide along the second slide rail 11, completing the displacement of the soldering iron tip 18 in the Z-axis direction. The third motor 15 is then started, and its output shaft rotates the third lead screw 13. The rotation of the third lead screw 13 causes the third moving block 14 to slide along the third slide rail 16, realizing the movement of the soldering iron tip 18 in the X-axis direction. The three motors work together to precisely deliver the soldering iron tip 18 to the solder joint position. While the soldering iron tip 18 is soldering, the fourth motor 26 is started. The output shaft of the machine 26 causes one of the conveyor wheels 24 to rotate. After one conveyor wheel 24 rotates, it drives the other conveyor wheel 24 to rotate synchronously in the opposite direction through two meshing gears 25. Then, the two conveyor wheels 24 clamp the solder wire and continuously convey it to the soldering iron tip 18. After being melted by the high-temperature soldering iron tip 18, the soldering is completed. During soldering, the temperature detector 27 monitors the temperature of the soldering iron tip 18 in real time to ensure that the soldering temperature is stable. The suction tube 20 on the fixed plate 19 is connected to the external suction device through a hose connected at one end to continuously extract the fumes generated by the soldering and optimize the working environment.
