Description

Technical Field

[0001] This utility model relates to PCB board processing equipment, and more particularly to a PCB board flipping mechanism. Background Technology

[0002] Existing PCB printing equipment typically involves PCB board loading, printing, and unloading processes. To meet the requirements of double-sided printing, a flipping station needs to be set up between the front printing station and the unloading station. Traditional PCB board flipping can be done manually or by a robotic arm. However, these flipping methods generally have drawbacks such as slow operation and high cost. Moreover, collision damage is likely to occur when picking up and placing PCB boards, which in turn leads to a decline in process quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flipping mechanism that can automatically input and output PCB boards, has high flipping efficiency, and can avoid damaging the PCB boards, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A PCB board flipping mechanism includes two flipping fixed seats, two flipping supports, a fixed conveying assembly, and a pressing conveying assembly. The pressing conveying assembly is symmetrically arranged above the fixed conveying assembly. The left and right ends of the fixed conveying assembly are respectively fixedly connected to the two flipping supports. The left and right ends of the pressing conveying assembly are respectively vertically slidably connected to the two flipping supports. Each of the two flipping supports is fixedly equipped with a lifting cylinder for driving the pressing conveying assembly to move up and down. The two flipping supports are respectively rotatably connected to the two flipping fixed seats. One of the two flipping fixed seats is fixed with a flipping drive mechanism for driving the two flipping supports to flip 180°.

[0006] Preferably, the fixed conveying assembly includes two fixed conveying supports arranged horizontally and parallel to each other, and a plurality of fixed conveying roller groups evenly distributed in the front-back direction are provided between the two fixed conveying supports.

[0007] Preferably, the pressing and conveying assembly includes two pressing and conveying supports arranged side by side and parallel to each other, and a plurality of pressing and conveying roller groups evenly distributed in the front-back direction are provided between the two pressing and conveying supports.

[0008] Preferably, one of the two tilting supports is fixed with a conveyor roller drive motor, which is used to drive the fixed conveyor roller group to operate.

[0009] Preferably, two lower support rods are fixed between the lower ends of the two fixed conveying brackets, and two upper support rods are fixed between the upper ends of the two pressing conveying brackets. The upper support rods are aligned with the lower support rods. A clamping cylinder is fixed on the upper support rod. The moving end of the clamping cylinder is provided with an upper clamp. A lower clamp is fixed on the lower support rod. The upper clamp and the lower clamp are aligned vertically.

[0010] In the PCB board flipping mechanism disclosed in this utility model, two flipping fixed seats provide support and fixation on the left and right sides, and two flipping supports are rotatably engaged with the two flipping fixed seats respectively. The fixed conveying component is fixedly arranged relative to the two flipping supports, and the pressing conveying component is vertically slidable relative to the two flipping supports. When the PCB board is conveyed between the fixed conveying component and the pressing conveying component, the lifting cylinder drives the pressing conveying component to move downward, clamping the PCB board between the pressing conveying component and the fixed conveying component. Then, the flipping driving mechanism drives the two flipping supports to flip 180° to complete the flipping. After the pressing conveying component rises, the fixed conveying component can convey the PCB board to the next workstation. Based on the above structure, it can be seen that this embodiment can automatically input and output PCB boards without relying on manual or robotic operation. It not only has high flipping efficiency but also effectively avoids damage to the PCB board. Attached Figure Description

[0015] Combination Figures 1 to 3As shown, this embodiment proposes a PCB board flipping mechanism, which includes two flipping fixed seats 40, two flipping supports 41, a fixed conveying assembly 42, and a pressing conveying assembly 43. The pressing conveying assembly 43 is symmetrically arranged above the fixed conveying assembly 42. The left and right ends of the fixed conveying assembly 42 are respectively fixedly connected to the two flipping supports 41. The left and right ends of the pressing conveying assembly 43 are respectively vertically slidably connected to the two flipping supports 41. The two flipping supports 41 are respectively fixed with lifting cylinders 44 for driving the pressing conveying assembly 43 to move up and down. The two flipping supports 41 are respectively rotatably connected to the two flipping fixed seats 40. One of the two flipping fixed seats 40 is fixed with a flipping drive mechanism 45, which is used to drive the two flipping supports 41 to flip 180°.

[0016] In the above structure, two flipping fixing seats 40 provide support and fixation on the left and right sides, and two flipping supports 41 are rotatably engaged with the two flipping fixing seats 40 respectively. The fixed conveying assembly 42 is fixedly arranged relative to the two flipping supports 41, and the pressing conveying assembly 43 is vertically slidably arranged relative to the two flipping supports 41. When the PCB board is conveyed between the fixed conveying assembly 42 and the pressing conveying assembly 43, the lifting cylinder 44 drives the pressing conveying assembly 43 to descend, clamping the PCB board between the pressing conveying assembly 43 and the fixed conveying assembly 42. Then, the flipping drive mechanism 45 drives the two flipping supports 41 to flip 180° to complete the flipping. After the pressing conveying assembly 43 rises, the fixed conveying assembly 42 can convey the PCB board to the next workstation. Based on the above structure, it can be seen that this embodiment can automatically input and output PCB boards without relying on manual or robotic operation. It not only has high flipping efficiency but also effectively avoids damage to the PCB board.

The pressing and conveying assembly 43 includes a plurality of roller shafts, each roller shaft having a plurality of second annular cams 439.

[0019] To better fit with the PCB board, the first annular cam 429 and the second annular cam 439 are aligned vertically.

[0020] In this embodiment, the roller shaft can be driven by a motor. Specifically, one of the two flip supports 41 is fixed with a conveyor roller drive motor 422, which is used to drive the fixed conveyor roller group 421 to operate.

[0021] As a preferred embodiment, two lower support rods 423 are fixed between the lower ends of the two fixed conveying brackets 420, and two upper support rods 433 are fixed between the upper ends of the two pressing conveying brackets 430.

The moving end of the clamping cylinder 434 is provided with an upper clamp 435. A lower clamp 425 is fixed on the lower support rod 423. The upper clamp 435 and the lower clamp 425 are vertically aligned.

[0022] In the above structure, the clamping cylinders 434 distributed on the front and rear sides can work with the upper and lower clamps to clamp the PCB board, further positioning the PCB board and effectively preventing the PCB board from shifting or slipping out during the flipping process.

All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
