[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Example

[0033] Combine Figure 1 This embodiment provides a semi-automatic soldering machine. A work platform 4 is provided at the bottom of the machine frame. A placement table 1 is provided on the work platform 4. A guide groove 11 is formed on the placement table 1. A positioning portion 2 is also provided on the placement table 1. The positioning portion 2 includes a sliding block 21 and a positioning block 22. The sliding block 21 slidably engages with the guide groove 11. A welding positioning area is formed between the positioning block 22 and the side wall of the placement table 1. The sliding block 21 slides within the guide groove 11 to adjust the width of the welding positioning area.

[0034] A soldering iron head 3 is arranged above the soldering positioning area, and is used for soldering the workpiece in the soldering positioning area. The soldering iron head 3 is connected with a driving unit, which is used for driving the soldering iron head 3 to move vertically. In a specific embodiment, the driving unit is a pneumatic device 9, such as a pneumatic cylinder, and a driving mechanism with the same function in the prior art can also be used.

[0035] The rack of the soldering machine is also provided with a temperature control device 8, which is used for controlling the temperature of the soldering iron head 3 according to the actual welding requirement. A temperature sensor is arranged on the soldering iron head 3 to realize real-time monitoring of the welding process temperature. By accurately controlling the welding temperature, the soldering points can be more uniform, full, and the problems of false welding and missed welding can be reduced.

[0036] The product to be welded is positioned in the soldering positioning area during welding. For example, in the production of mutual inductors, a large number of soldering points can be quickly welded, and the speed is much faster than manual welding. In the embodiment, when the product to be welded is replaced, the position of the sliding block 21 only needs to be adjusted to realize the adjustment of the width of the soldering positioning area, so as to meet the demand of flexible production, and the adjustment is convenient and time-saving. It can be suitable for welding of parts of different sizes and has high flexibility. The rack of the soldering machine in the embodiment is also provided with a control device 7, which is used for controlling the welding parameters, such as welding temperature and air blowing time.

[0037] In a specific embodiment, a first key groove hole 23 is arranged on the sliding block 21, and the first key groove hole 23 is used for rotating a screw to position the sliding block 21 in the guide groove 11. In actual operation, after the screw is rotated out, the sliding block 21 is released from the positioning and can move along the guide groove 11. The sliding block 21 moves and makes the positioning block 22 abut against the product to be welded. At this time, the screw is rotated in to position the product and determine the width of the soldering positioning area. In a specific embodiment, the sliding block 21 and the positioning block 22 are integrally connected and in T shape.

[0038] In a specific embodiment, the placement table 1 is positioned on the working platform 4 by a depressible pressing plate 6. The pressing plate 6 is rotatably arranged on the mounting seat 5, and is used for rotating above the placement table 1 to position the placement table 1 by pressing from below. That is, the position of the placement table 1 on the working platform 4 can also be adjusted, and after the position is adjusted to a suitable position, the position can be fixed by pressing the pressing plate 6. A second key groove hole 61 is arranged on the pressing plate 6, and the second key groove hole 61 is used for rotating a screw to press the pressing plate 6. In actual operation, after the screw in the second key groove hole 61 is rotated out, the pressing plate 6 can be rotated. After rotating above the placement table 1, the screw is rotated in to position the pressing plate 6 and make the pressing plate 6 press to fix the placement table 1.

[0039] The specific operation steps are explained below. During the actual operation, first place the insert to be welded in the welding positioning area of ​​the placement table 1. Adjust the sliding block 21 accordingly according to the size of the insert to adapt the width of the welding positioning area. Determine the positioning size and tighten the corresponding screws to ensure that the insert does not loosen in the welding positioning area. Then use air blowing to ensure that the parts cool down in time after welding. Then set the welding parameters, such as welding temperature and air blowing time, by operating the control device 7, and heat the soldering iron tip 3 to the set temperature. When the workpiece to be welded is placed on the mold, step on the foot switch, and the soldering iron tip 3 is pressed down to transfer heat to the object to be welded, and the solder wire is sent to melt the solder, thereby welding the workpieces together. Release the soldering iron tip 3 for one second, and the air blowing will work to help the solder joint cool down quickly. Example

[0040] This embodiment differs from Example 1 in that a smoking pipe is provided on the side of the welding positioning area, with the opening of the smoking pipe facing the welding positioning area. Furthermore, an air pipe 10 is provided on the side of the welding positioning area, with the opening of the air pipe 10 facing the welding positioning area. The air pipe 10 is inserted into a steering knuckle 12, and the distance between the opening of the air pipe 10 and the welding positioning area can be adjusted by rotating the steering knuckle 12.

[0041] In this embodiment, the air blowing function of the air pipe 10 primarily utilizes compressed air to rapidly remove heat and achieve rapid cooling. In a specific embodiment, a time relay can be used to control the blowing time. Furthermore, from the perspective of the air outlet, a suitable angle allows the airflow to directly affect the solder joint and surrounding area. Therefore, in this embodiment, a steering knuckle 12 is provided to ensure that the air pipe 10 can be adjusted to meet the blowing requirements. In a specific embodiment, the steering knuckle 12 is a "ball joint." For example, when the soldering iron tip 3 is raised and returned to its original position, the air outlet is aligned with the solder joint at an angle of 20°-50°. This allows the airflow from the air pipe 10 to maximize contact with the solder joint surface, allowing heat to dissipate quickly. The actual blowing volume can be adjusted according to actual conditions. A larger blowing volume can remove more heat per unit time. When sufficient air flows rapidly through the solder joint, heat is absorbed and carried away by the air, much like a gust of wind quickly drying water stains on the ground. The blowing mode can be adjusted to continuous or intermittent blowing according to the time. The continuous air blowing can maintain a continuous cooling effect, allowing the solder joint to cool down quickly after welding is completed; the intermittent air blowing can be flexibly controlled according to the actual situation of the solder joint.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
