[0029] See also Figures 1 to 8A wire harness welding structure is applied to welding equipment, including a base body 1, a circuit board 2 and a wire harness 3. The base body 1 is provided with a receiving cavity 11, a wire groove 12 and a first through hole 13. One end of the wire groove 12 is connected with the receiving cavity 11, and the other end of the wire groove 12 is connected with the outside. The first through hole 13 is connected with the receiving cavity 11, and the first through hole 13 is located above the receiving cavity 11. The first through hole 13 is used for quantitatively allowing molten solder to pass through. The circuit board 2 is received in the receiving cavity 11, and one end of the wire harness 3 passes through the wire groove 12 and extends to the surface of the circuit board 2. The wire harness 3 is provided with a first welding position, and the first welding position corresponds to the first through hole 13. The other end of the wire harness 3 extends out of the wire groove 12 and extends to the outside.

[0030] Further, in order to prevent the molten solder from directly contacting the surface of the base body 1, please refer to Figures 1 to 3 , further comprising a printed steel mesh 4 connected to the base body 1, the printed steel mesh 4 being provided with a second through hole 41, the second through hole 41 being correspondingly connected to the first through hole 13, and the second through hole 41 being located above the first through hole 13, and the printed steel mesh 4 being used to carry the scraper 7 and the molten solder. It can be understood that, unlike the printed steel mesh 4 connected to the base body 1 in this embodiment, in some other embodiments, the base body 1 and the printed steel mesh 4 are two independent structures, for example, the printed steel mesh 4 is grafted onto the welding equipment and relies on the transmission structure and positioning structure of the welding equipment to move to the top of the base body 1 to cooperate with the base body 1 to achieve quantitative welding.

[0031] For the working process of the above wire harness welding structure, please refer to Figures 1 to 3 In some embodiments, the details are as follows: first, the molten solder is transported to the surface of the printed steel mesh 4 away from the base 1, so that the surface of the printed steel mesh 4 away from the base 1 is loaded with the molten solder, and then, the driving structure of the welding equipment drives the scraper 7 to move on the surface of the printed steel mesh 4 away from the base 1, so that the scraper 7 pushes the molten solder to move to the second through hole 41, and then, the molten solder passes through the second through hole 41 and the first through hole 13 in turn and falls to the first welding position, and finally, the drying structure of the welding equipment or natural cooling is used to solidify the molten solder at the first welding position to achieve the welding fixation and connection of the wiring harness 3 and the circuit board 2.

[0032] Further, in order to improve the welding stability of the wiring harness 3 and the circuit board 2, or to facilitate the reasonable wiring layout of the wiring harness 3, please refer to Figures 1 to 3The seat body 1 is also provided with a third through hole 14, which is connected to the receiving cavity 11, and the third through hole 14 is spaced apart from the first through hole 13. The printed steel mesh 4 is also provided with a fourth through hole 42, which is correspondingly connected to the third through hole 14, and the fourth through hole 42 is located above the third through hole 14. The wiring harness 3 is also provided with a second welding position, and the second welding position corresponds to the third through hole 14. In the above manner, the molten solder can be solidified at the second welding position, so that the wiring harness 3 and the circuit board 2 can add the second welding position in the presence of the first welding position, thereby effectively improving the overall welding stability of the wiring harness 3 and the circuit board 2. It should be noted that the first welding position is the connection and conduction position of the wiring harness 3 and the circuit board 2, and the second welding position is the non-connection and conduction position of the wiring harness 3 and the circuit board 2. It should also be noted that when the wiring harness 3 and the circuit board 2 need to have multiple connection conduction positions, according to actual needs, multiple first through holes 13, second through holes 41 are opened and multiple first welding positions are set; or, when the wiring harness 3 and the circuit board 2 need to have multiple non-connection conduction positions to facilitate wiring layout, according to actual needs, multiple third through holes 14, fourth through holes 42 are opened and multiple second welding positions are set.

[0033] For the above-mentioned first through hole 13, second through hole 41, third through hole 14 and fourth through hole 42, in order to avoid the molten solder remaining on the contact surface between the seat body 1 and the printed steel plate during the falling process, please refer to the figure. In some embodiments, the aperture of the first through hole 13 is equal to the aperture of the second through hole 41, and the aperture of the third through hole 14 is equal to the aperture of the fourth through hole 42. For the above-mentioned first through hole 13, second through hole 41, third through hole 14 and fourth through hole 42, in order to simplify the structure of the wire harness welding structure, in some embodiments, the first through hole 13, second through hole 41, third through hole 14 and fourth through hole 42 are all in the same shape. It can be understood that the shapes of the first through hole 13, second through hole 41, third through hole 14 and fourth through hole 42 include but are not limited to one of square, circular, elliptical or polygonal.

The cover plate 16 is detachably connected to the base 15. The cover plate 16 and the first groove 151 are enclosed to form a receiving cavity 11, and the cover plate 16 and the second groove 152 are enclosed to form a wire groove 12. The first through hole 13 and the third through hole 14 are located on the cover plate 16. The detachable connection method between the cover plate 16 and the base 15 includes but is not limited to one of magnetic connection, snap connection, threaded connection or clamping connection. It should be noted that the area of ​​the first groove 151 is equal to or similar to the area of ​​the circuit board 2. When the circuit board 2 is accommodated in the accommodating cavity 11, the circuit board 2 is clamped in the first groove 151 by clamping. Since the area of ​​the first groove 151 is equal to or similar to the area of ​​the circuit board 2, the circuit board 2 is in a relatively fixed state in the first groove 151 and will not shake, which is beneficial to improving the welding quality of the circuit board 2 and the wiring harness 3.

[0035] Further, in order to make the wire duct 12 compatible with the wire harness 3, please refer to Figures 4 to 6 The cover plate 16 is provided with a third groove 161, and the third groove 161 corresponds to the second groove 152, and the third groove 161 and the second groove 152 are enclosed together to form the wire groove 12. Among them, the third groove 161 and the second groove 152 are both arc-shaped, which can be adapted to the arc surface of the wire harness 3, and when the base 15 and the cover plate 16 are connected, the arc surfaces of the third groove 161 and the second groove 152 cooperate to clamp the wire harness 3, thereby improving the stability of the wire harness 3, avoiding shaking or deviation of the wire harness 3 during welding, and is conducive to improving the welding quality of the wire harness 3 and the circuit board 2.

[0036] Further, in order to realize the detachable connection between the base 15 and the cover 16, please refer to Figure 7 and Figure 8 , and also includes a first magnetic component 5 and a second magnetic component 6.

The guide block 162 is located at the periphery of the cover plate 16, and the guide groove 153 is located at the periphery of the base 15.

[0038] Further, in the process of magnetic attraction and cooperation between the first magnetic member 5 and the second magnetic member 6, in order to guide the first magnetic member 5 and the second magnetic member 6 to accurately position, please refer to Figure 7 and Figure 8 , the first magnetic member 5 is arranged at the bottom of the guide groove 153, and the second magnetic member 6 is arranged on the surface of the guide block 162 facing the guide groove 153. Among them, the shape of the first magnetic member 5 is the same as the shape of the guide groove 153, and the shape of the second magnetic member 6 is the same as the shape of the guide block 162. For example, in some embodiments, the guide groove 153 and the guide block 162 are both semi-annular, and the first magnetic member 5 and the second magnetic member 6 are also semi-annular. Through the above-mentioned semi-annular setting, the contact area of ​​the first magnetic member 5 and the second magnetic member 6 can be increased, which is conducive to improving the assembly firmness of the base 15 and the cover plate 16, and then improving the clamping stability of the wire harness 3 by the wire groove 12. It can be understood that in some other embodiments, the guide groove 153, the guide block 162, the first magnetic member 5 and the second magnetic member 6 also include but are not limited to square, circular or other irregular shapes. It can also be understood that, in some embodiments, there is only the first magnetic component 5, or only the second magnetic component 6. When there is only the first magnetic component 5, the first magnetic component 5 is arranged at the bottom of the guide groove 153, and the guide block 162 is made of metal so that the first magnetic component 5 and the guide block 162 can be attracted to each other.
