Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] Example: like Figures 1 to 5 As shown, this application provides an automatic soldering mechanism for a soldering machine, including: a soldering mechanism 10, including a support frame 11, a rotating frame 12 disposed in the middle of the support frame 11, and a rotating component 13 disposed at the connection between the rotating frame 12 and the support frame 11; a front-to-back adjustment component 14 disposed in the middle of the rotating frame 12, and a clamping component 15 connected to one end of the front-to-back adjustment component 14; the clamping component 15 includes a drive cylinder 151, a connecting component 152, and a clamping block 153; a solder pot structure 20 disposed on one side of the soldering mechanism 10, including a flux tank 21, a solder pot tank 22, and a fume extraction pipe 23; a soldering machine table 30 for supporting the soldering mechanism 10 and the solder pot structure 20; a first U-shaped photoelectric sensor and a first trigger rod installed between the support frame 11 and the rotating frame 12; and a second U-shaped photoelectric sensor and a second trigger rod installed between the rotating frame 12 and the front-to-back adjustment component 14; According to the appendix Figure 1 As can be seen, the tin-dipping mechanism 10 and the tin furnace structure 20 are installed on the upper end of the welding machine table 30. The upper end of the welding machine table 30 is also equipped with a corresponding wire harness pulling mechanism, wire stripping mechanism and conveying mechanism, which are not shown in the figure. Therefore, only the tin-dipping mechanism 10 and the tin furnace structure 20 are shown. In actual use, the support frame 11 and the rotating frame 12 can be rotated by the rotating component 13. The rotation angle is set and controlled by the first U-shaped photoelectric sensor and the first trigger rod. The front and rear adjustment component 14 drives the clamping component 15 to descend and adjust the depth of soldering and fluxing. The depth is set and controlled by the second U-shaped photoelectric sensor and the second trigger rod, so that the angle of wire harness rotation and the depth of soldering can be adjusted, thereby improving the soldering efficiency.

[0022] By adopting the above technical solution, the wire harness after stripping can be clamped by the connecting component 10. The rotating component 13 drives the rotating frame 12 and the clamping component 15 to rotate, applying flux and solder. Then, the front and rear adjustment component 14 controls the clamping component 15 to reciprocate, so that the ends of the wire harness are inserted into the flux and solder respectively, performing an automated soldering operation. This solves the problems of manual soldering in the prior art: the operator has to hold the wire harness and immerse it in the solder bath, which poses a risk of scalding from molten solder splashes, and the soldering time and depth are difficult to unify, resulting in unstable soldering quality; semi-automatic soldering equipment: although equipped with a simple clamping mechanism, the angle of wire harness rotation and the depth of soldering descent cannot be controlled, resulting in low overall efficiency.

[0023] It should be noted that when the wire harness needs to be soldered, the wire harness is first pulled to one side of the clamping assembly 15 by the external wire pulling mechanism. The output end of the drive cylinder 151 drives the end of the connecting assembly 152 to move laterally. Then the connecting assembly 152 is hinged and rotated, which further drives the two sets of clamping blocks 153 to clamp the wire harness. When the clamping block 153 contacts the wire harness, the anti-slip block will contact the wire harness first and then feed back to the pressure sensor. At the same time, it will drive the guide rod to move along the inside of the guide groove. When the pressure sensor detects that the pressure value reaches the set value, it feeds back to the external controller, thereby controlling the output end of the drive cylinder 151 to stop running. Thus, the clamping operation of wire harnesses of different thicknesses can be performed. Next, the first stepper motor 131 is started, so that the output end of the first stepper motor 131 drives the first synchronous pulley 132 and the synchronous belt to rotate, which in turn drives the driven pulley 133 and the rotating frame 12 to rotate, which in turn drives the rotating shaft to rotate along the first rotating hole, and at the same time drives the rotating support wheel 134 to rotate along the second rotating hole, and at the same time drives the front and rear adjustment assembly 14 and the clamping assembly 15 to rotate, further rotating the head of the wire harness to the upper end of the flux tank 21; Next, the second stepper motor 141 is started, causing the output end of the second stepper motor 141 to drive a set of second synchronous pulleys 143 to rotate. With the connection of the synchronous belt, it drives another set of second synchronous pulleys 143 to rotate. Finally, it drives the lead screw 142 to rotate along the inside of the lead screw holder 145, causing the lead screw holder 145 to drive the moving plate 144 and the moving block 148 to move laterally. The moving block 148 moves along the inside of the moving hole 149, while driving the connecting plate 1410 and the clamping assembly 15 to move downward, so that the end of the wire harness is inserted into the inside of the flux tank 21. Then, the above steps are reversed to move the wire harness upward, thereby completing the flux application operation. Finally, the rotating component 13 continues to drive the rotating frame 12, the front and rear adjustment component 14, the clamping component 15 and the wire harness to rotate at an angle, so that the end of the wire harness rotates to the upper end of the solder bath 22. The front and rear adjustment component 14 is activated, and the clamping component 15 and the wire harness are inserted into the inside of the solder bath 22 and then removed, thereby completing the soldering operation.

[0024] In an optional embodiment, the rotating assembly 13 includes a first stepper motor 131 mounted on one side of the support frame 11. The output end of the first stepper motor 131 is connected to a first synchronous pulley 132. A driven pulley 133 is mounted on one side of the rotating frame 12. A synchronous belt is provided between the first synchronous pulley 132 and the driven pulley 133. A rotating shaft is provided at the connection between the driven pulley 133 and the rotating frame 12. The first synchronous pulley 132 and the synchronous belt can be driven to rotate by the output of the first step motor 131, which in turn drives the driven pulley 133 and the rotating shaft to rotate, thus driving the rotating frame 12 to rotate, in order to prepare for the subsequent rotation of the clamping assembly 15 and the wire harness to be coated with flux and solder.

[0025] In an optional embodiment, it further includes: a first rotating hole formed on one side of the support frame 11 and adapted to the rotating shaft, which provides a supporting effect and ensures that the driven wheel 133 can perform a stable rotational support function; a rotating support wheel 134 provided on the other side of the rotating frame 12; and a second rotating hole formed on the other side of the support frame 11 and adapted to the rotating support wheel 134. During the rotation of the rotating frame 12, the rotational stability between the rotating support wheel 134 and the second rotating hole can be guaranteed.

[0026] In an optional embodiment, the front and rear adjustment assembly 14 includes a second stepper motor 141 and a lead screw 142 installed inside the rotating frame 12. A second synchronous pulley 143 is installed at the output end of the second stepper motor 141 and at one end of the lead screw 142. A synchronous belt is provided on the outer side of the second synchronous pulley 143. The lead screw 142 can be rotated by a synchronous belt, which facilitates the subsequent forward and reverse rotation of the lead screw 142 along the inside of the lead seat 145. This causes the lead seat 145 to move the moving block 148, the moving hole 149, and the clamping assembly 15 back and forth, completing the soldering and resetting operation of the wire harness end.

[0027] In an optional embodiment, a lead screw 142 is adapted to be connected to a lead screw seat 145, and a movable plate 144 is fixedly connected to the outer side of the lead screw seat 145. A slider 146 is installed on one side of the movable plate 144 by bolts, and a slide rail 147 adapted to the slider 146 is installed on the inner wall of the rotating frame 12. During the lateral movement of the movable plate 144, the slider 146 can slide along the outside of the slide rail 147 to ensure stability during the lateral movement.

[0028] In an optional embodiment, a movable block 148 is fixedly connected to one side of the movable plate 144, and a movable hole 149 adapted to the movable block 148 is opened in the middle of the rotating support wheel 134. After the clamping assembly 15 is tinned and coated with flux, it needs to be reset in time so that the moving block 148 can move along the inside of the moving hole 149. This ensures that the moving block 148 can drive the clamping assembly 15 to move through the connecting plate 1410. The end of the moving block 148 is connected to the connecting plate 1410, and the other side of the connecting plate 1410 is connected to the drive cylinder 151. After the clamping assembly 15 clamps the wire harness, it can drive the wire harness to move back and forth.

[0029] In an optional embodiment, it further includes: an anti-sliding block disposed on the clamping surface of the clamping block 153, and a pressure sensor disposed between the anti-sliding block and the clamping block 153; guide rods symmetrically distributed on one side of the anti-sliding block; and guide grooves formed on the clamping surface of the clamping block 153 and adapted to the guide rods. When the clamping block 153 contacts the wire harness, the anti-slip block will first contact the wire harness and then feed back to the pressure sensor. At the same time, it will drive the guide rod to move along the inside of the guide groove. When the pressure sensor detects that the pressure value reaches the set value, it feeds back to the external controller, thereby controlling the output end of the drive cylinder 151 to stop running, so that wire harnesses of different thicknesses can be clamped.
