DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figures 1 to 4 As shown, the utility model provides a technical solution for a flipping device for PCB board processing: the flipping device for PCB board processing comprises two sets of mounting frames 1 arranged symmetrically, the bottom of the mounting frame 1 is connected to a driving mechanism for adjusting the position thereof, the top of the mounting frame 1 is installed with a fixing plate, one side of the fixing plate is installed with a driving motor 2, the other side of the fixing plate is installed with a rotary cylinder 3, the output shaft of the driving motor 2 is connected to the rotary cylinder 3, the rotary cylinder 3 is connected with a connecting piece 4, the rotary cylinder 3 drives the connecting piece 4 to rotate, the front section of the connecting piece 4 is fixedly installed with a telescopic cylinder 5, the telescopic cylinder 5 The cylinder 5 is provided with output shafts for output in the upward and downward directions respectively, and a pressing plate 6 is provided on each of the output shafts in the two directions. When the telescopic cylinder 5 contracts, the two pressing plates 6 gather together, and when the telescopic cylinder 5 extends, the two pressing plates 6 separate. In addition, a connecting plate is provided on each side of the connecting member 4, and the two connecting plates extend in the direction of the telescopic cylinder 5 to wrap the telescopic cylinder 5. A limiting plate 7 is provided on the ends of the two connecting plates, and the limiting plate 7 is located in the gap between the pressing plate 6 and the telescopic cylinder 5. A photoelectric positioner 12 is provided on the pressing plate 6 on one side.
[0021] The driving mechanism includes two groups of first linear motors 8, one group of second linear motors 11, three groups of directional screw rods 9 and a servo motor 10 for driving the directional screw rods 9, wherein the two groups of directional screw rods 9 cooperate with the two groups of first linear motors 8 to control the two groups of mounting frames 1 to move closer to or farther away from each other, and this part of the driving components are all installed on a substrate with a guide rail, and another group of directional screw rods 9 and the second linear motor 11 drive the substrate to move the directional screw rods 9, and the directional screw rods 9 are vertically arranged between the two directional screw rods 9 above, and the directional screw rods 9 cooperate with the servo motor 10 to adjust the position of the overall flip device on the PCB production line.
[0022] The stacked plates that have been nailed and rubber-wrapped are transported to the flap device through a through-type conveying mechanism. Before the conveying mechanism drives the stacked plates to dock with the flap device, the first linear motor 8 and the directional screw rod 9 symmetrically arranged on the driving mechanism adjust the distance between the mounting frames 1 on both sides so that the distance between the limit plates 7 on both sides can be adapted to the size of the stacked plates. Then the directional screw rod 9 and the second linear motor 11 under the base plate cooperate with each other to dock the flap device as a whole with the conveying mechanism. During docking, the stacked plates first contact the inclined plates at the edges of the limit plates 7. Through the guidance of the inclined plates on both sides, the position of the stacked plates is regularized and guided so that the stacked plates are restricted within the clamping range of the pressure plates 6. Further guidance and driving are carried out so that the stacked plates are in the center of the flap device. Then the telescopic cylinder 5 works to control the two pressure plates 6 to gather together so as to The plate is clamped therein. During this process, the photoelectric positioner 12 monitors the position of the stacked plate in real time. After the clamping is completed, the directional screw rod 9 and the second linear motor 11 at the bottom work to transfer the stacked plate from the front conveying mechanism. When the flipping device moves to the middle section of the second linear motor 11, the drive motor 2 works to drive the connecting part 4 to rotate, and then drives the stacked plate to rotate. After the rotation is completed, the directional screw rod 9 and the second linear motor 11 at the bottom continue to work and continue to move away from the front conveying mechanism to dock the flipped stacked plate with the rear conveying mechanism, and then transport the stacked plate away. After completing the flipping of a single stacked plate, there is no need to flip the next stacked plate. The next stacked plate can be transported to the subsequent conveying mechanism through the pressing plate 6.
[0023] This method allows the stacks on the conveying mechanism to be flipped and arranged at intervals. When stacking, the top caps of the pins on the stacks are butted against each other to avoid collision between the nail heads on one stack and another stack, which would cause scratches on the stacks.
