Detailed Implementation

[0014] 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.

[0015] Please see Figures 1 to 7 This utility model provides a technical solution: a PCB board positioning mechanism for a horizontal insertion machine, including an operating table 100, a conveyor frame 101 slidably connected above the operating table 100, a tilting frame 102 slidably connected below the conveyor frame 101, a positioning shaft 103 rotatably connected above the tilting frame 102, mounting frames 104 fixedly connected to both sides of the conveyor frame 101, and multiple evenly distributed teeth 105 arranged in an array below the mounting frames 104. The positioning shaft 103 has a first tooth fixedly connected to both ends of the tilting frame 102. The wheel 106 and the positioning shaft 103 are equipped with a positioning component. The positioning shaft 103 is positioned above the conveyor frame 101. After the positioning component positions the PCB board, when the flipping frame 102 moves, the first gear 106 on both sides comes into contact with the teeth 105. The resistance of the teeth 105 causes the first gear 106 to deflect. Under the action of the teeth 105 and the first gear 106 meshing, the PCB board inside the positioning shaft 103 can be flipped, which helps to improve work efficiency.

[0016] Please see Figures 1 to 4 The present invention provides a technical solution: a drive screw 110 is rotatably connected below the conveyor frame 101. The drive screw 110 is perpendicular to the tilting frame 102 and is threadedly connected to the tilting frame 102. The drive screw 110 can provide driving force for the movement of the tilting frame 102.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: the positioning component includes a positioning groove 120 opened in the positioning shaft 103, a pair of clamping pieces 121 are slidably connected inside the positioning groove 120, the positioning shaft 103 is provided with an installation groove 122, a pair of toothed plates 123 are slidably connected inside the installation groove 122, the two toothed plates 123 are staggered, the clamping pieces 121 are fixedly connected to the toothed plates 123, when the toothed plates 123 on both sides move, they can synchronously drive the clamping pieces 121 inside the positioning groove 120 to move towards each other or in opposite directions, which is more convenient to use.

[0018] Please see Figures 1 to 7This utility model provides a technical solution: a second gear 130 is rotatably connected inside the mounting groove 122, and the second gear 130 meshes with the toothed plate 123. A servo motor 131 is fixedly connected inside the mounting groove 122, and the output end of the servo motor 131 is fixedly connected to the second gear 130. Under the action of the servo motor 131, the deflection angle of the second gear 130 can be precisely controlled, making it more practical.

[0019] Please see Figures 1 to 5 This utility model provides a technical solution: a pair of conveying shafts 132 are rotatably connected inside the conveying frame 101. When the PCB board above the conveying frame 101 is pushed by the conveying shafts 132, the damage caused by the movement of the PCB board can be reduced, which is beneficial to improving the use effect.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a drive groove 140 is provided inside the operating table 100, and a pair of rotating shafts 141 are rotatably connected inside the drive groove 140. The two rotating shafts 141 are connected to each other by a conveyor belt 142. A drive motor 143 is fixedly connected inside the operating table 100. The output end of the drive motor 143 is fixedly connected to one of the rotating shafts 141. The conveyor belt 142 moves on the two rotating shafts 141. When the drive motor 143 drives one of the rotating shafts 141 to move, the movement of the conveyor belt 142 can be controlled, making the operation more convenient.

[0021] During operation (or use): First, the PCB board is pushed into the positioning shaft 103 above the conveyor frame 101 by the conveying device. Then, the servo motor 131 is started to drive the second gear 130 to rotate. The second gear 130 synchronously drives the toothed plates 123 on both sides to move towards each other. The clamping plates 121 on both sides contact the PCB board, thus fixing the PCB board. Then, the drive motor 143 is started to drive one of the rotating shafts 141 to rotate, causing the conveyor belt 142 to move. The conveyor belt 142 drives the conveyor frame 101 to slide towards the other side of the operating table 100. When the conveyor frame 101 moves to the middle position, the drive screw 110 drives the tilting frame 102 to slide on the conveyor frame 101. When the first gear 106 contacts the teeth 105, This causes the positioning shaft 103 to deflect. When the first gear 106 passes through the tooth 105, the positioning shaft 103 rotates 180 degrees. At the same time, the flipping frame 102 slides from one side of the conveyor frame 101 to the other side, thus realizing the automatic flipping of the PCB board, which is more convenient to use. When the conveyor frame 101 moves to the other side of the operating table 100, the reverse start servo motor 131 drives the second gear 130 to rotate, so that the clamping plates 121 on both sides move away from the PCB board, thereby releasing the fixation of the PCB board. Then, the start drive screw 110 drives the flipping frame 102 to slide on the conveyor frame 101, and pushes the PCB board out of the conveyor frame 101 through the positioning groove 120. The flipped PCB board is transported by an external conveying device, which helps to improve work efficiency.
