Description
Technical Field
[0001] This utility model relates to the field of flipping machine technology, and in particular to an automatic flipping machine for PCBA boards. Background Technology
[0002] PCBA boards, also known as printed circuit boards, are important electronic components. They serve as the support for electronic components and provide the connections between them. Because they are manufactured using electronic printing technology, they are called "printed" circuit boards. Before the advent of printed circuit boards, the interconnection between electronic components relied on direct wire connections to form complete circuits. Circuit boards existed primarily as effective experimental tools, while printed circuit boards have achieved a dominant position in the electronics industry.
[0003] When existing PCBA boards undergo processes such as surface mounting and soldering during production, the orientation of the PCBA board surface usually needs to be changed repeatedly. Automatic flipping machines are usually installed on conveyor belts and can only flip the PCBA board once, which reduces their practicality. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, such as Figure 1-5As shown, this utility model provides an automatic PCBA board flipping machine, including a working plate 1. A moving groove 3 is provided at the top and near the center of the working plate 1. A screw 5 is provided inside the moving groove 3. A moving plate 4 is threaded onto the surface of the screw 5. A first U-shaped plate 6 is fixedly connected to the top of the moving plate 4. This allows the screw 5 to rotate, which in turn moves the moving plate 4, and the moving plate 4 moves the first U-shaped plate 6. A transmission belt 12 is installed at the top and near both ends of the first U-shaped plate 6. A rotating rod 13 is connected to the inside of the transmission belt 12 and near both ends. Both ends of the rotating rod 13 are rotatably connected to the inner walls of both ends of the first U-shaped plate 6 and to their bearings. A second motor 14 is symmetrically fixedly connected to one side wall of the first U-shaped plate 6. The output end of the second motor 14 passes through the first U-shaped plate 6 and is fixedly connected to one end of the rotating rod 13. This allows the second motor 14 to drive the rotating rod 13 to rotate, and the rotation of the rotating rod 13 drives the transmission belt 12 to move. A second U-shaped plate 15 is fixedly connected inside the mold plate 6 and near its center. A rotating column 16 is provided inside the second U-shaped plate 15. A sleeve 17 is fitted and fixedly connected to the surface of the rotating column 16. A groove 18 is opened on the surface of the sleeve 17. Both ends of the rotating column 16 pass through the first U-shaped plate 6 and are rotatably connected to its bearings. A half gear 19 is fixedly connected to one end of the rotating column 16. A rotating gear 23 is meshed with the bottom of the half gear 19. A fixing member 21 is fixedly connected to one side wall of the first U-shaped plate 6 and below the rotating gear 23. A third motor 22 is fixedly connected to the surface of the fixing member 21. The output end of the third motor 22 passes through the fixing member 21 and is fixedly connected to the rotating gear 23. This allows the third motor 22 to drive the rotating gear 23 to rotate. The rotation of the rotating gear 23 drives the half gear 19 to rotate. The rotation of the half gear 19 drives the rotating column 16 to rotate. The rotation of the rotating column 16 drives the sleeve 17 to rotate. The rotation of the sleeve 17 can rotate the PCBA board in the groove 18 by 180 degrees.
[0023] Example 2, as Figure 1-5As shown, support legs 2 are fixedly connected to the bottom of the work plate 1 near its four corners. The support legs 2 are trapezoidal in shape and serve to support the bottom of the work plate 1. Both ends of the screw 5 penetrate the inner walls of the moving groove 3 and are rotatably connected to its bearings. A first motor 11 is fixedly connected to one end of the work plate 1 near its center. The output end of the first motor 11 is fixedly connected to one end of the screw 5, enabling the first motor 11 to drive the screw 5 to rotate. Grooves 7 are symmetrically formed at the bottom of the first U-shaped plate 6. Limiting strips 8 are embedded and slidably connected inside the grooves 7. The bottom of the limiting strips 8 is connected to the work plate 1. The top of the working plate 1 is fixedly connected, which can limit the bottom of the working plate 1 by the limiting strip 8. Limiting grooves 9 are opened at the top of the working plate 1 and near both sides. Limiting plates 10 are embedded and slidably connected inside the limiting grooves 9. Limiting rods 24 are slidably connected through the center of each limiting plate 10. Both ends of the limiting rods 24 are fixedly connected to the inner walls of the limiting grooves 9. This can limit the first U-shaped plate 6 by the limiting plates 10 and the limiting rods 24. Limiting blocks 20 are fixedly connected at the teeth of the half gear 19 and near both ends. This can limit the half gear 19.
[0024] Working principle: By placing the PCBA board onto the transmission belt 12, the second motor 14 drives the rotating rod 13 to rotate, which in turn drives the transmission belt 12 to rotate. At this time, one end of the PCBA board on the transmission belt 12 can be embedded into the groove 18 on the surface of the sleeve 17. Then, the third motor 22 drives the rotating gear 23 to rotate, which in turn drives the rotating column 16 to rotate. The rotating column 16 drives the sleeve 17 to rotate 180 degrees back and forth, which can achieve the effect of repeatedly flipping the PCBA board, thereby achieving the function of flipping direction according to actual conditions. The first motor 11 drives the screw 5 to rotate, which drives the moving plate 4 to move, which in turn drives the first U-shaped plate 6 to move, which can adjust the position of the PCBA board on the first U-shaped plate 6, thereby enabling the PCBA board to be moved to different processing steps for processing.
