[0002] In the electronics manufacturing industry, automatic soldering machines are widely used for soldering components on PCBs (printed circuit boards) to replace inefficient and inconsistent manual operations. The feeding mechanism is a key upstream component for achieving automated production, and its technical performance directly affects the soldering machine's operating efficiency and quality.

[0003] In the prior art, Chinese utility model with announcement number CN216607556U discloses an automatic feeding soldering machine. Through the cooperation between the feeding mechanism, the pushing mechanism and the soldering mechanism, it adopts an automatic feeding method to improve work efficiency, replace manual labor to complete various soldering tasks, effectively save manpower, save time, reduce labor intensity, improve labor efficiency, and improve the soldering quality and output of products.

[0004] However, traditional feeding mechanisms require waiting for the previous workpiece to complete before pushing it away and then pushing the next workpiece into the station. This makes it difficult to perform the feeding and soldering processes simultaneously, leading to a prolonged soldering cycle and reduced production efficiency. Therefore, this invention proposes a feeding mechanism for an automatic soldering machine to solve these problems. Utility Model Content

The two clamps are located at both ends of the diameter of the flip rings. The cross-section of the clamp is "E". The conveyor frame transports the substrate to be processed to the lower inner cavity of the clamp. Two fixed plates are fixedly connected to the upper side of the upright frame.

DETAILED DESCRIPTION OF EMBODIMENTS

[0015] In order to clearly and completely describe the objectives and technical solutions of the present utility model and make its advantages clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, not all of them, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present utility model.

[0016] Example 1, please refer to Figures 1-7 , the present utility model provides a technical solution: a feeding mechanism for an automatic soldering machine, comprising: a conveyor frame 1.

[0017] Specifically, a substrate to be processed 2 is conveyed on the conveyor frame 1, the cross section of the conveyor frame 1 is a "匚"-shape with an upward opening, conveying chains are installed on both inner side walls of the conveyor frame 1, two side edges of the substrate to be processed 2 are respectively located above the two conveying chains, the conveyor frame 1 is a prior known technology, the conveying chains on the inner wall of the conveyor frame 1 can also be replaced by a conveyor belt, the substrate to be processed 2 is placed in the inner cavity of the conveyor frame 1, and the middle part of the substrate to be processed 2 is suspended, which can prevent the conductive copper layer and electronic components at the middle position of the substrate to be processed 2 from being worn; a notch is arranged in the middle of the conveyor frame 1, a vertical frame 4 fixedly connected to the ground is arranged at the notch, the position of the vertical frame 4 is fixed, the height of the vertical frame 4 is lower than the height of the substrate to be processed 2 conveyed on the conveyor frame 1, a clamp 7 is arranged above the vertical frame 4, both ends of the clamp 7 are fixedly connected with turning rings 8, two clamps 7 are provided and are symmetrically distributed between the two turning rings 8, the two clamps 7 are respectively located at two ends of the diameter of the turning rings 8, as Figure 4As shown, the two clamps 7 and two flipping rings 8 form an integrated structure. When the flipping rings 8 rotate around their own center, they can drive the clamps 7 to flip. The cross-section of the clamps 7 is "E" shaped. The conveyor frame 1 conveys the substrate 2 to be processed to the lower inner cavity of the clamps 7. Figure 3 As shown, when the rotating ring 8 drives the clamp 7 to rotate, the positions of the upper and lower inner cavities of the clamp 7 are interchanged. At this time, the upper and lower positions of the two substrates 2 to be processed in the upper and lower inner cavities of the clamp 7 are interchanged. While the substrate 2 to be processed in the upper position is being soldered, the substrate 2 to be processed in the lower position can be loaded and unloaded, thereby shortening the soldering cycle. Secondly, two fixing plates 5 are fixedly connected to the upper side of the upright frame 4. Two rotating shafts 52 are rotatably installed between the two fixing plates 5. The rotating shafts 52 are rotatably connected to the fixing plates 5 through bearings. The rotating shafts 52 can only rotate but will not shift in position. The two rotating shafts 52 are located on both sides of the lower part of the flip ring 8. Support shafts 6 are connected to both ends of the rotating shafts 52, and the support shafts 6 support the outer side of the flip ring 8. Figure 3 As shown, the flip ring 8 is pressed on the support shaft 6 under the action of gravity. When the rotating shaft 52 drives the support shaft 6 to rotate, the support shaft 6 can drive the flip ring 8 to rotate through friction. In addition, both the support shaft 6 and the flip ring 8 are circular structures. According to actual needs, the support shaft 6 and the flip ring 8 can also maintain transmission through the meshing of tooth grooves, which will not be elaborated here.

[0018] To ensure the stability of the relative position between the substrate 2 and the fixture 7 after the substrate 2 is slid into the inner cavity, this application further includes a protective frame 3 that partially covers both sides of the substrate 2. The protective frame 3 is pre-installed at the edge of the substrate 2 and is mainly used to protect the substrate 2 and prevent damage to the edge of the substrate 2. A first magnet 31 and a second magnet 71 are respectively fixedly embedded in the middle of the surface of the protective frame 3 and the middle of the inner wall of the fixture 7. After the substrate 2 is slid into the inner cavity of the fixture 7, the first magnet 31 and the second magnet 71... Corresponding to 71, since the substrate 2 to be processed has its own inertia during the conveying and moving process, by setting the cooperation of magnet block 31 and magnet block 71, the substrate 2 to be processed can be stably positioned after sliding into the inner cavity of the fixture 7. When the conveyor 1 continues to convey the next substrate 2 to be processed, and the next substrate 2 to be processed slides into the inner cavity of the fixture 7, the next substrate 2 to be processed will generate a pushing force on the previous substrate 2 to be processed, thereby pushing the previous substrate 2 to be processed out of the inner cavity of the fixture 7, thus realizing loading and unloading.

[0019] To ensure the stable horizontal placement of the substrate 2 to be processed within the cavity of the clamp 7, this application also includes a fixing rod 51 fixedly connected between the two fixing plates 5 to improve the stability of the installation position of the two fixing plates 5. Two symmetrically distributed arc-shaped limiting plates 53 are fixed to the side of one fixing plate 5, and the arc-shaped limiting plates 53 are movably sleeved on the outside of the rotating shaft 52. The arc-shaped limiting plates 53 are fixed in position and do not affect the rotation of the rotating shaft 52. A first magnet 54 and a second magnet 72 are fixed to the inner wall of the arc-shaped limiting plate 53 and the outer wall of the clamp 7, respectively. When the clamp 7 rotates and flips, the second magnet 72 corresponds to the first magnet 54, and then... Figure 4 and Figure 3 As shown, the cooperation between magnet 72 and magnet 54 ensures that the clamp 7 remains stable in a horizontal position. When the clamp 7 is flipped, it can maintain its position after flipping 180 degrees, thus avoiding errors caused by the flipping angle of the clamp 7, which would prevent the substrate 2 to be processed from being placed horizontally. This indirectly reduces the soldering error of the substrate 2 to be processed by the subsequent soldering machine.

[0020] In order to drive the rotating shaft 52 to rotate, this application also has a drive motor fixedly installed on the stand 4. Both the output shaft of the drive motor and the rotating shaft 52 are fixedly fitted with pulleys 55. The drive motor drives the rotating shaft 52 to rotate through the transmission belt. The drive motor is connected to an external power source to provide power for the rotation of the rotating shaft 52.

[0021] To automatically correct the position of the substrate 2 to be processed within the fixture 7, one end of the support shaft 6 in this application is designed as a hollow structure, and a groove 63 is formed on the inner wall of one end of the support shaft 6. A protrusion 521 is fixed to one end of the rotating shaft 52. When the rotating shaft 52 rotates, the protrusion 521 rotates and slides within the groove 63. Figure 6 and Figure 7 As shown, when the rotating shaft 52 rotates, it does not immediately drive the support shaft 6 to rotate. There is a certain relative rotational margin between the support shaft 6 and the fixed plate 5. Therefore, the flipping ring 8 and the clamp 7 have a free rotational margin within a certain angle range. The advantage of this design is that it provides a certain rotational margin to the clamp 7 and the flipping ring 8, so that even if the clamp 7 flips at an angle less than 180 degrees or more than 180 degrees, the magnetic piece 2 72 and the magnetic piece 1 54 can attract and cooperate with each other to automatically correct the position of the clamp 7, thereby ensuring that the substrate 2 to be processed inside the clamp 7 remains in a horizontal position.

[0022] To prevent slippage between the support shaft 6 and the flip ring 8 during rotation, this application further includes a retaining ring 61 and a flexible sleeve 62 fixedly sleeved on the outside of the support shaft 6. The retaining ring 61 fits against the side of the flip ring 8, and friction textures are formed on the outer wall of the flip ring 8. The flexible sleeve 62 contacts the friction textures on the outer wall of the flip ring 8. The flexible sleeve 62 itself can undergo micro-elastic deformation to increase the contact friction between it and the flip ring 8, thereby preventing slippage between the two.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
