[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 As shown, the utility model provides a technical solution: a flip machine for PCB board processing, comprising a control cabinet 1, a workbench 2 is fixedly connected to one side of the control cabinet 1, a first support frame 3 is fixedly connected to the top of the workbench 2, a conveying device 5 is installed on the top of the first support frame 3, a first slide groove 14 is opened on the top of the workbench 2, a second support frame 4 is slidably connected inside the first slide groove 14, a flip gripper 6 is installed on one side of the control cabinet 1, and a sensor 7 is installed on one side of the first support frame 3. During the processing, the PCB board is conveyed by the first support frame 3. When the processing of one side of the PCB board is completed, the first support frame 3 conveys the PCB board to the position of the flip gripper 6. When the sensor 7 senses the thickness of the PCB board, the control cabinet 1 controls the flip gripper 6 to flip the PCB board. After flipping, the PCB board is put back on the conveying device 5 and conveyed to the next process. By moving the position of the second support frame 4, the equipment can be suitable for PCB boards of different specifications.

[0023] Reference Figure 3 As shown, in the present embodiment: a storage groove 8 is provided on one side of the second support frame 4, and a U-shaped limit rod 9 is slidably connected inside the storage groove 8; a plurality of limit grooves 10 used in conjunction with the storage groove 8 are provided on one side of the workbench 2; the surface of the storage groove 8 is slidably connected to the inside of the limit groove 10; after the user moves the second support frame 4 to a suitable position according to the size of the PCB board, the U-shaped limit rod 9 is pushed to make the U-shaped limit rod 9 enter the inside of the limit groove 10, thereby limiting the position of the second support frame 4 to prevent the vibration during the operation of the equipment from causing the second support frame 4 to be displaced, causing the PCB board to fall from the conveying device 5.

[0024] Reference Figure 3As shown, in the present embodiment: limiting grooves 11 are provided at the top and bottom of the storage groove 8, and the top and bottom of the U-shaped limiting rod 9 are fixedly connected with limiting sliders 12, and the surface of the limiting slider 12 is slidably connected to the inside of the limiting groove 11. When the user needs to adjust the position of the second support frame 4, the U-shaped limiting rod 9 is pulled to disengage the U-shaped limiting rod 9 from the inside of the limiting groove 10, thereby releasing the limitation on the second support frame 4. In the process of pulling the U-shaped limiting rod 9, the limiting sliders 12 at the top and bottom of the U-shaped limiting rod 9 slide inside the limiting groove 11, thereby limiting the movement of the U-shaped limiting rod 9 and preventing the U-shaped limiting rod 9 from disengaging from the inside of the storage groove 8.

[0025] Reference Figure 3 As shown, in the present embodiment: a tension spring 13 is fixedly connected to one side of the storage groove 8, and the other end of the tension spring 13 is fixedly connected to one end of the U-shaped limit rod 9. When the user pulls the U-shaped limit rod 9, the tension spring 13 at one end of the U-shaped limit rod 9 accumulates force. After moving the second support frame 4 to a suitable position, the U-shaped limit rod 9 is released, and the U-shaped limit rod 9 is pulled into the interior of the limit groove 10 under the tension of the tension spring 13 to limit the second support frame 4. At the same time, the tension of the tension spring 13 can prevent the U-shaped limit rod 9 from being vibrated and detached from the interior of the limit groove 10.

[0026] Reference Figure 4 and Figure 5 As shown, in the present embodiment: a second slide groove 15 is provided at the bottom of the first slide groove 14, a first slider 16 is fixedly connected to the bottom of the first slide groove 14, and the surface of the first slider 16 is slidably connected to the inside of the second slide groove 15. When the user moves the second support frame 4, the first slider 16 at the bottom of the second support frame 4 slides inside the second slide groove 15 to assist the movement of the second support frame 4 and prevent the second support frame 4 from tilting and causing movement jamming.

[0027] Reference Figure 5 As shown, in this embodiment: a placement groove 17 is provided at the bottom of the first slider 16, and a pulley 18 is slidably connected inside the placement groove 17. The surface of the placement groove 17 fits with the bottom inside the second slide groove 15. When the user moves the second support frame 4, the placement groove 17 at the bottom of the first slider 16 follows the movement of the second support frame 4 and slides on the bottom surface inside the second slide groove 15, thereby reducing the friction force when the second support frame 4 moves, making the movement of the second support frame 4 more labor-saving, and reducing the wear on the bottom of the first slider 16.

[0028] Reference Figure 2As shown, in this embodiment: the top of the second support frame 4 is fixedly connected with a placement plate 19, and by setting the top of the second support frame 4 to a low-friction material, the PCB board will not be affected by the friction force during the transmission of the conveying device 5, resulting in asynchronous movement of the two sides, causing the PCB board to tilt, resulting in the flip gripper 6 being unable to clamp.

[0029] Working principle: During the processing of the PCB board, it is conveyed by the first support frame 3. When one side of the PCB board is processed, the first support frame 3 conveys the PCB board to the position of the flip gripper 6. When the sensor 7 senses the thickness of the PCB board, the flip gripper 6 is controlled by the control cabinet 1 to flip the PCB board. After flipping, the PCB board is put back on the conveying device 5 and conveyed to the next process. By moving the position of the second support frame 4, the equipment can be applied to PCB boards of different specifications. After moving the second support frame 4 to a suitable position according to the size of the PCB board, the U-shaped limit rod 9 is pushed to make the U-shaped limit rod 9 enters the interior of the limiting groove 10 to limit the position of the second support frame 4 to prevent the vibration during the operation of the equipment from causing the second support frame 4 to be displaced, causing the PCB board to fall from the conveying device 5. When the position of the second support frame 4 needs to be adjusted, the U-shaped limiting rod 9 is pulled to make the U-shaped limiting rod 9 disengage from the interior of the limiting groove 10 to release the limitation of the second support frame 4. In the process of pulling the U-shaped limiting rod 9, the limiting sliders 12 at the top and bottom of the U-shaped limiting rod 9 slide in the limiting slide groove 11 to limit the movement of the U-shaped limiting rod 9 to prevent the U-shaped limiting rod 9 from being disengaged from the interior of the storage groove 8. In the process of moving the U-shaped limit rod 9, the tension spring 13 at one end of the U-shaped limit rod 9 accumulates force. After the second support frame 4 is moved to a suitable position, the U-shaped limit rod 9 is released, and the U-shaped limit rod 9 is pulled into the interior of the limit groove 10 under the tension of the tension spring 13 to limit the second support frame 4. At the same time, the tension of the tension spring 13 can prevent the U-shaped limit rod 9 from being vibrated and detached from the interior of the limit groove 10. In the process of moving the second support frame 4, the first sliding block 16 at the bottom of the second support frame 4 slides inside the second sliding groove 15 to assist the movement of the second support frame 4 and prevent the second support frame 4 from being The frame 4 tilts and causes movement jams. During the movement of the second support frame 4, the placement groove 17 at the bottom of the first slide block 16 follows the movement of the second support frame 4 and slides on the bottom surface inside the second slide groove 15, reducing the friction force when the second support frame 4 moves, making the movement of the second support frame 4 more labor-saving and reducing the wear on the bottom of the first slide block 16. By setting the top of the second support frame 4 to a low-friction material, the PCB board will not be affected by the friction force during the transmission of the conveying device 5, resulting in asynchronous movement of the two sides, causing the PCB board to tilt and making it impossible for the flip gripper 6 to clamp.
