Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a PCB flipping device. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), as electronic products develop towards multifunctionality and high integration, the application of multilayer boards and double-sided boards is becoming increasingly widespread. To enable circuit routing and component mounting on both sides of the board, double-sided processing of the PCB is typically required, involving multiple steps such as drilling, milling, silkscreen printing, surface mount technology (SMT), reflow soldering, and testing. In this double-sided processing flow, it is inevitable to flip the PCB that has been processed on one side to the other side for subsequent processing operations; this process is commonly referred to in the industry as "flipping" or "turning over."

[0003] Traditional PCB flipping operations rely heavily on manual labor, where operators manually remove boards from processing equipment or conveyor lines, flip them 180 degrees, and then place them back in their original positions. However, the drawbacks of manual flipping are becoming increasingly apparent: First, manual operation is inefficient and difficult to match the pace of high-speed automated production lines, becoming a production bottleneck; second, manual flipping easily leads to bumps, scratches, or contamination of boards, especially for boards that have already undergone precision mounting or soldering, which may cause components to fall off or solder joints to be damaged; at the same time, long-term repetitive labor also increases labor costs and occupational health risks.

[0004] Although some automated production lines have introduced mechanical flipping devices, existing equipment still suffers from problems such as complex structure, poor adaptability, and easy vibration or drop of boards during the flipping process. This is especially true when handling PCBs of different thicknesses or materials, where versatility and stability are insufficient. Therefore, there is an urgent need for an automatic flipping device that is structurally sound, operates stably, is highly adaptable, and can effectively protect PCBs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1-4A PCB flipping device includes a frame 1, and further includes: two sets of conveyor belts 2 for conveying PCBs, both rotatably connected to the frame 1; a flipping shaft 3, rotatably connected to the frame 1, located between the two sets of conveyor belts 2; a flipping plate 4 fixedly connected to the flipping shaft 3; a clamping groove 401 provided on the flipping plate 4, with clamping components for fixing the PCBs provided in the clamping groove 401; and a driving component provided on the frame 1 for driving the flipping shaft 3 to rotate. In use, the PCBs are conveyed by one of the conveyor belts 2 and enter the frame 1. The PCB board is fixed in the clamping slot 401 by the clamping component. Then, the drive component is activated, which rotates the flipping plate 4 180 degrees clockwise, so that the PCB board falls onto another set of conveyor belts 2. Finally, the clamping component releases the clamp on the PCB board, and the PCB board continues to be conveyed under the drive of the other set of conveyor belts 2, thus realizing the flipping of the PCB board. It has a simple structure. By using the clamping component, it can not only be used to flip PCB boards of different thicknesses, improving versatility, but also avoid problems such as easy shaking or falling of the board during the flipping process, thus improving stability.

[0022] Reference Figures 1-3 Specifically, the two sets of conveyor belts 2 include a first conveyor belt and a second conveyor belt. The conveying direction of the first conveyor belt is the same as that of the second conveyor belt, and they are connected end to end. The flipping plate 4 is located between the first and second conveyor belts. When the drive unit is working, the opening of the clamping groove 401 turns from the output end of the first conveyor belt to the input end of the second conveyor belt. That is, the first conveyor belt conveys the PCB board to the second conveyor belt. During the conveying process, the PCB board slides into the clamping groove 401. At this time, the clamping member clamps the PCB board. Then, the drive unit drives the flipping plate 4 to rotate 180 degrees clockwise, so that the opening of the clamping groove 401 faces the second conveyor belt. At this time, the clamping member releases the clamping member from the PCB board, and the PCB board falls onto the second conveyor belt, realizing the flipping.

[0023] Reference Figure 3 and Figure 4 Here, the clamping component includes a clamping plate 5 that is vertically connected within the clamping groove 401. The clamping plate 5 extends along the length of the clamping groove 401. A cylinder 6 is fixedly connected to the bottom of the flipping plate 4, and the output end of the cylinder 6 is fixedly connected to the clamping plate 5. When the output end of the cylinder 6 extends, the clamping plate 5 moves closer to the top of the clamping groove 401. In use, after the PCB board enters the clamping groove 401, the cylinder 6 is activated to drive the clamping plate 5 to rise, thus clamping the PCB board between the clamping plate 5 and the top of the clamping groove 401. Furthermore, guide rods 501 are fixedly connected to both ends of the clamping plate 5, and both guide rods 501 are slidably connected to the bottom of the clamping groove 401. During use, this ensures that the clamping plate 5 can be reliably raised and lowered, reducing the possibility of tilting.

[0024] Reference Figure 3 and Figure 4 A second clamping pad 502 is fixedly connected to the top of the clamping plate 5, and a first clamping pad 403 corresponding to the second clamping pad 502 is fixedly connected to the inner top of the clamping groove 401. When clamping, the first clamping pad 403 and the second clamping pad 502 abut against the two end faces of the PCB board, respectively. Furthermore, the first clamping pad 403 and the second clamping pad 502 are made of rubber. In use, by using the first clamping pad 403 and the second clamping pad 502 to clamp the PCB board, not only can the problem of damaging the PCB board be reduced, but the clamping stability can also be improved.

[0025] Reference Figure 3 and Figure 4 A buffer pad 402 is fixedly connected to the side wall of the clamping groove 401. The side wall of the PCB board abuts against the buffer pad 402. The buffer pad 402 is made of rubber. In use, by fixing the buffer pad 402 to the side wall of the clamping groove 401, when the PCB board enters the clamping groove 401, the board can avoid direct impact with the clamping groove 401, thus improving the protection effect on the board.

[0026] Reference Figure 1 and Figure 2 Here, the driving component includes a servo motor 301 fixedly connected to the frame 1. The output end of the servo motor 301 is fixedly connected to the flipping shaft 3. The model of the servo motor 301 is 60GB5HT. In use, by starting the servo motor 301, the flipping plate 4 is rotated 180 degrees clockwise, which can realize the flipping of the plate. After the flipping is completed, it is rotated 180 degrees counterclockwise to reset the flipping plate 4, which is convenient for flipping the next plate.

[0027] Reference Figures 1-3 Baffles 7 are detachably connected to both sides of the frame 1. A fixing plate 701 is fixedly connected to the baffle 7. The fixing plate 701 has a waist-shaped hole. Bolts are threaded through the waist-shaped hole and connected to the frame 1 to fix the baffle 7 to the frame 1. When it is necessary to adjust the position of the baffle 7, the bolts are loosened, and the baffle 7 can be adjusted towards or away from the conveyor belt 2. The baffle 7 is located on the side wall of the conveyor belt 2. The two sides of the PCB board abut against the inner wall of the corresponding baffle 7. The baffle 7 is made of plastic. In use, by installing baffles 7 on both sides of the frame 1, the board can be guided and limited, improving the conveying effect.
