[0002] Circuit boards, also known as printed circuit boards (PCBs), are an indispensable component of electronic devices. They achieve electrical connections between electronic components by laying copper foil on an insulating substrate and etching the desired circuit pattern. Circuit boards can carry a variety of electronic components, from simple to complex, such as resistors, capacitors, transistors, and integrated circuits, ensuring proper signal transmission and power distribution between them. Depending on functional requirements, circuit boards can be designed as single-layer, double-layer, or multi-layer structures. Circuit boards are almost indispensable in modern electronic products, and can be found in household appliances, computers, communications equipment, and the automotive industry.

DETAILED DESCRIPTION
[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0021] Embodiment: A circuit board flattening device, such as Figure 1-Figure 5 As shown, it includes a first placement rack 1, a second placement rack 2, a connecting plate 3, an electric push rod 4, a pressure plate 5, a connection rack 6, a rotating shaft 7, a collection frame 10, a sliding plate 11, a second elastic member 12, a cylinder 13, a push plate 14 and a fan 15. The rear side of the first placement rack 1 is fixedly connected to the second placement rack 2, the top of the second placement rack 2 is fixedly connected to the connecting plate 3, the front side of the connecting plate 3 is fixedly connected to the electric push rod 4, the push rod of the electric push rod 4 is fixedly connected to the pressure plate 5, the pressure plate 5 is located above the first placement rack 1, and the left side of the first placement rack 1 is fixedly connected to the connection rack 6. The connection rack 6 is tilted and the interior of the connection rack 6 rotates between the front and back. It is connected to a rotating shaft 7, which is set at an angle. The front side of the first placement rack 1 is fixedly connected to a collection frame 10, and a sliding plate 11 is slidably connected to the inside of the collection frame 10. A rubber pad is connected to the top of the sliding plate 11. The rubber pad can reduce the impact force of the circuit board falling on the sliding plate 11, thereby protecting the circuit board. A second elastic member 12 is fixedly connected between the bottom of the sliding plate 11 and the bottom of the collection frame 10. The second elastic member 12 is set as a coil spring. The top of the second placement rack 2 is fixedly connected to a cylinder 13, and a push plate 14 is fixedly connected to the piston rod of the cylinder 13. A fan 15 for cooling the circuit board is installed on the top of the collection frame 10.
[0022] When the circuit board needs to be flattened, the circuit board is first heated, and then the heated circuit board is placed on the shaft 7 at one end of the connecting frame 6 away from the first placement frame 1. Under the rotation of the shaft 7, the circuit board slides along the connecting frame 6 on the shaft 7, so that the circuit board slides to the top of the first placement frame 1, and then the electric push rod 4 drives the pressing plate 5 thereon to move downward to squeeze the circuit board, so that the circuit board can be flattened. The electric push rod 4 drives the pressing plate 5 to move upward away from the circuit board. Under the action of the fan 15, the temperature of the circuit board can be reduced, so that the circuit board is cooled and shaped. Then, the cylinder 13 drives the push plate 14 to move forward to push the flattened circuit board into the collection frame 10 to complete the collection. When the circuit board falls into the collection frame 10, the cylinder 13 drives the push plate 14 to move back The subsequent circuit boards slide from the connecting rack 6 onto the first placement rack 1 for flattening operation, thereby realizing continuous flattening processing of the circuit boards. There is no need to manually place the circuit boards under the flattening machine, which improves the flattening efficiency and reduces the safety hazards during the flattening operation. When the circuit board falls on the sliding plate 11, under the action of the gravity of the circuit board, the second elastic member 12 changes from the normal state to the compressed state, and the sliding plate 11 slides downward. The second elastic member 12 can play a buffering role to prevent the circuit board from colliding with the collection frame 10 and causing damage. When the circuit board in the collection frame 10 needs to be taken out, the circuit board on the sliding plate 11 is manually taken out. After all the circuit boards are taken out, the second elastic member 12 returns to the normal state from the compressed state, and the sliding plate 11 slides upward and reset under the elastic force of the second elastic member 12.
[0023] like Figure 1-Figure 4 As shown, it also includes an inclined plate 8 and a first elastic member 9. The top of the first placement rack 1 is slidably connected to the inclined plate 8. A buffer pad is provided on the side of the inclined plate 8 close to the connecting rack 6. The buffer pad can prevent the circuit board from colliding with the inclined plate 8 and causing damage. A first elastic member 9 is fixedly connected between the inclined plate 8 and the first placement rack 1. The elastic force of the first elastic member 9 is greater than the gravity of the circuit board. The first elastic member 9 is set as a coil spring. When the circuit board slides from the connecting frame 6 to the first placement frame 1, the circuit board collides with the inclined plate 8, and the inclined plate 8 slides away from the connecting frame 6. The first elastic member 9 is compressed. Under the elastic force of the first elastic member 9, the inclined plate 8 slides and resets to move the circuit board to just below the pressing plate 5. When flattening the circuit board, the pressing plate 5 moves downward to squeeze the inclined surface of the inclined plate 8, so that the inclined plate 8 slides away from the circuit board. The first elastic member 9 is compressed. When the flattening is completed and the pressing plate 5 moves upward, the pressing plate 5 moves away from the inclined plate 8. The first elastic member 9 returns to its original state and causes the inclined plate 8 to slide and reset, thereby completing a flattening operation. The inclined plate 8 can move the circuit board to the specified position for flattening to prevent the circuit board from sliding out of the first placement frame 1. It can also position the circuit board to ensure that the circuit board is located just below the pressing plate 5.
[0024] like Figure 1 and Figure 5 As shown, it also includes a motor 61, a fixing frame 62 and a gear lever 63. The motor 61 is installed on the outer wall of the connecting frame 6. The fixing frame 62 is connected to the output shaft of the motor 61. The left and right sides of the fixing frame 62 are slidably connected to the gear lever 63. The gear lever 63 is slidably connected to the connecting frame 6. The gear lever 63 passes through the connecting frame 6. The distance between the gear lever 63 and the rotating shaft 7 is less than the thickness of the circuit board.
[0025] When the circuit board slides along the connecting frame 6 through the rotating shaft 7, the fixing frame 62 is driven to rotate by the motor 61, so that the gear rod 63 slides along the fixing frame 62 and the connecting frame 6, and the left gear rod 63 slides forward on the connecting frame 6 away from the rotating shaft 7, and the right gear rod 63 slides backward on the connecting frame 6 close to the rotating shaft 7. The circuit board is blocked by the right gear rod 63 and stays on the rotating shaft 7. The fixing frame 62 is then driven to reverse by the motor 61, so that the left gear rod 63 slides close to the rotating shaft 7, and the right gear rod 63 slides away from the rotating shaft 7. The circuit board slides to the first placement rack 1, and the left gear rod 63 blocks the subsequent circuit board from moving. The above steps are repeated. After the circuit board is pushed into the collection frame 10, the motor 61 is controlled to rotate forward and reverse, so that gap unloading can be achieved.
[0026] The above is a detailed introduction to the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, based on the idea of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
