[0034] The welding pen 1 is provided with a tin storage part 13, which can store tin. The tin storage part 13 adopts a cavity with an electric heating wire outside, which is used to melt solid tin. The rear end of the welding pen 1 is provided with an air pressure device 12, and the pen tip is provided with a tin outlet 11. The circulation channel connects the outflow port of the tin storage part 13 and the tin outlet 11, so that the tin melts and flows out through the circulation channel. In actual use, the air pressure of the air pressure device 12 can be controlled to push the tin heated into liquid in the tin storage part 13, so that it enters the outflow channel from the outflow port, and then flows out through the tin outlet 11 through the circulation channel. The air pressure device 12 can also be used to control the amount of tin discharged from the tin outlet 11, so that the tin can flow out evenly, better control the amount of tin used, effectively control its amount, and ensure the quality of welding. The fixing clamp 312 and the welding plate 311 can fix the wire harness, prevent the deviation caused by manual lifting of the wire harness, and improve the accuracy of welding.

[0035] In some embodiments of the present application, a support mechanism 2 is further included, the support mechanism 2 is fixedly connected to the welding table 3, and a mobile pen cover 21 is a hollow cylindrical structure, the welding pen 1 is fixed in the mobile pen cover 21, and the mobile pen cover 21 is fixedly connected to the support mechanism 2. The welding pen 1 is perpendicular to the welding plate 311, and the welding spot groove is located directly below the welding pen 1.

[0036] The welding pen 1 is fixed in the mobile pen cover 21, and the mobile pen cover 21 can move relative to the supporting mechanism 2, so that the pen tip of the welding pen 1 contacts the welding point of the wiring harness. By fixing the welding pen 1, the position deviation caused by manual hand holding of the welding pen 1 is prevented, thereby further improving the welding accuracy, improving the welding efficiency, and further improving the welding quality.

[0037] In some embodiments of the present application, the movable connection between the movable pen cover 21 and the supporting mechanism 2 is connected by an electric sliding mechanism.

[0038] The use of an electric sliding mechanism can avoid the instability of manual operation and is also easy to realize the function of active control, further improving welding quality and welding efficiency.

[0039] In some embodiments of the present application, the electric sliding mechanism adopts one of an electric ball screw and a linear motor.

[0040] One of the electric ball screw and linear motor can stably realize welding action, provide a physical basis for autonomous control of welding, and further improve welding quality and welding efficiency.

[0041] In some embodiments of the present application, the fixing clamp 312 has two symmetrically placed fixing plates and two supporting frames corresponding to the fixing plates, the two fixing plates are movably connected to their respective corresponding supporting frames, and the length of the fixing plates is between 3 cm and 5 cm.

[0042] The fixing plate is used to fix the wire harness. When placing the wire harness, the wire harness can be tightened by two fixing plates placed opposite to each other. The length of the fixing plate is between 3 cm and 5 cm. On the one hand, a longer length can fix the wire harness more firmly. On the other hand, the length of the fixing plate should not be too long, otherwise the installation efficiency will be reduced, resulting in a decrease in the overall efficiency of the welding process to ensure welding efficiency. After actual measurement, a length of 3 cm to 5 cm can be applied to most wire harness welding, and will not cause unstable clamping, decreased welding efficiency or quality due to different bending degrees or directions of the wire harness.

[0043] In some embodiments of the present application, the width of the fixing plate is between 2 cm and 3.5 cm.

[0044] After many tests, the width of the fixing plate between 2 cm and 3.5 cm can be suitable for clamping most wire harnesses. Thicker wire harnesses can also be well fixed, and the welding efficiency or quality will not be reduced due to the thickness of the wire harness.

[0045] In some embodiments of the present application, the solder joint groove is rhombus-shaped and is disposed in the middle of the wiring harness groove.

[0046] The soldering point groove is set to a diamond shape so that excess tin can form a diamond shape at the soldering point, which is convenient for shaping the soldering point position and convenient for grinding after welding to facilitate insertion into the insulating rubber sleeve, further improving the efficiency of the welding process and ensuring the welding quality.

[0047] In some embodiments of the present application, the depth of the wiring harness groove is between 0.2 cm and 0.7 cm.

[0048] The harness groove is provided on the welding plate 311, and the welding plate 311 is detachable. The welding plate 311 can be set with harness grooves of different depths according to different harnesses. The depth of the harness groove is between 0.2 cm and 0.7 cm, which can be suitable for most common harnesses. If it is too shallow, the harness will be unstable and affect the welding quality. If it is too deep, the harness will be inconvenient to load and unload, affecting the efficiency of the welding process.
