[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example 1: As Figures 1-5 As shown, this utility model provides a PCB board automatic flip-calibration docking platform, including: a fixed frame 1, a support base 2 fixedly connected to the upper surface of the fixed frame 1, a rotating shaft 3 rotatably sleeved inside the support base 2, the rotating shaft 3 being fixedly connected to one end of a flip rod 4, an electric gripper 5 being fixedly connected to the other end of the flip rod 4, a docking platform 6 being provided on the lower side of the electric gripper 5, calibration blocks 7 being slidably connected around the upper surface of the docking platform 6, the bottom of the calibration block 7 being rotatably connected to one end of a connecting rod 8 via a pin 22, the other end of the connecting rod 8 being rotatably connected to a rotating block 9 via a pin 22, the rotating block 9 being fixedly sleeved on a drive shaft 10, and the drive shaft 10 being rotatably installed inside the docking platform 6.

[0022] More specifically: The flipping device is fixed by the fixing frame 1, the bottom of the fixing frame 1 is fixedly installed on the frame, and the support base 2 supports the rotating shaft 3. The reciprocating rotation of the rotating shaft 3 drives the flipping rod 4 to rotate 180 degrees, thereby causing the electric gripper 5 to clamp and flip the PCB board, so that the PCB board is flipped onto the docking platform 6. At this time, the rotation of the drive shaft 10 drives the rotating block 9 to rotate. Under the rotational connection of the pin shaft 22 and the connecting rod 8, the rotating block 9 drives the calibration block 7 to move, so that the calibration block 7 moves on the upper surface of the docking platform 6 in the direction of the axis of the drive shaft 10. Then, the calibration block 7 centers and calibrates the PCB board and fixes it, thereby avoiding the problem that the slight vibration of the docking platform 6 during the movement may easily cause the PCB board to shift, thereby affecting the accurate positioning of the PCB board and thus affecting subsequent processing or inspection.

[0023] Example 2: Figures 2 to 4 As shown, based on Embodiment 1, a transmission gear 11 is fixedly sleeved at one end of the rotating shaft 3, and a rack 12 meshes with the bottom of the transmission gear 11. The two sides of the rotating shaft 3 are rotatably sleeved on the support base 2. One end of the rotating shaft 3 is fixedly connected to the transmission gear 11, and the transmission gear 11 meshes with the rack 12 for transmission. One side of the rack 12 is fixedly connected to the L-shaped plate 13. The bottom of the L-shaped plate 13 is slidably connected to the limiting rail 14. One side of the L-shaped plate 13 is fixedly connected to the rack 12. The bottom of the L-shaped plate 13 is limited by the limiting rail 14. The lower surface of the limiting rail 14 is fixedly connected to the fixed frame 1. One end of the L-shaped plate 13 is fixedly connected to the output end of the electric cylinder 15. The electric cylinder 15 is fixedly installed on the upper surface of the fixed frame 1. A moving block 16 is provided on one side of the bottom of the fixed frame 1. The electric cylinder 15 is electrically connected to the external terminal controller.

[0024] More specifically, after the processing device on the side of the fixed frame 1 away from the docking platform 6 has finished processing one side of the PCB board, the retraction of the electric cylinder 15 drives the L-shaped plate 13 to move. The L-shaped plate 13 pulls the rack 12 fixedly connected to it to move. The rack 12 slides under the limit of the limit rail 14, so that the rack 12 meshes with the transmission gear 11. The transmission gear 11 drives the rotating shaft 3 fixedly sleeved inside to rotate. Under the rotation of the rotating shaft 3, the flipping rod 4 rotates, so that the flipping rod 4 rotates from the side close to the docking platform 6 to the side of the fixed frame 1 away from the docking platform 6. The electric gripper 5 clamps the PCB board. Then, the output end of the electric cylinder 15 is extended, so that the flipping rod 4 drives the electric gripper 5 to flip in the opposite direction again, flipping the unprocessed side of the PCB board onto the docking platform 6. The electric gripper 5 is electrically connected to the external controller.

[0025] Example 3: Figures 3 to 5As shown, on the basis of embodiment two, the upper surface of the moving block 16 is fixedly connected with the docking station 6, a threaded rod is sleeved on one side of the moving block 16, a sliding rod is sleeved on the other side of the moving block 16, and the bottom of the docking station 6 is driven by the threaded rod and limited by the sliding rod through the moving block 16, so that the docking station 6 can be driven by the moving block 16 to move close to or away from the fixed frame 1, thereby realizing the conveying of the PCB board. The motor 17 is fixedly installed on the inner bottom of the docking station 6, the output end of the motor 17 is fixedly sleeved with a pinion 18, one side of the pinion 18 is engaged with a large gear 19, the large gear 19 is fixedly sleeved on the outer circle surface of the drive shaft 10, the motor 17 is electrically connected with an external controller, the external controller is electrically connected with the contact sensor 21, and the upper and lower ends of the drive shaft 10 are rotatably sleeved in the support bearing. The upper surface of the docking station 6 is provided with a sliding groove 20, the sliding groove 20 is slidably connected with the calibration block 7, and the calibration block 7 is fixedly installed on one side of the contact sensor 21. The drive shaft 10 is limited by the support bearing, so as to ensure the stability of rotation, and the sliding groove 20 limits the calibration block 7.

[0026] More specifically, when the turnover rod 4 drives the electric clamping jaw 5 to turn to one side of the docking station 6, the moving block 16 drives the docking station 6 to move towards the fixed frame 1, and vice versa. When the electric clamping jaw 5 turns away from the docking station 6, the moving block 16 drives the docking station 6 to move away from the fixed frame 1. When the turnover rod 4 places the PCB board on the upper surface of the docking station 6 through the electric clamping jaw 5, the motor 17 is started at this time through the external controller, the motor 17 drives the pinion 18 to rotate, the pinion 18 and the large gear 19 are engaged and transmitted, the large gear 19 drives the drive shaft 10 to rotate, and the drive shaft 10 drives the rotating block 9 fixedly sleeved on the top to rotate. The rotating block 9 drives the calibration block 7 to move under the action of the rotating connection of the pin shaft 22 and the connecting rod 8, so that the calibration block 7 moves on the upper surface of the docking station 6 towards the axis direction of the drive shaft 10.

[0027] The contact sensor 21 is fixedly installed on each of the four calibration blocks 7. When each contact sensor 21 detects that the edge of the PCB board contacts, a high-level signal is sent to the external controller. The external controller continuously monitors the signal state of the four contact sensors 21. When the external controller detects that the four contact sensors 21 simultaneously send high-level signals, it is determined that the four surfaces of the PCB board are in contact. At this time, the external controller controls the motor 17 to stop rotating, thereby making the calibration block 7 centering and calibrating the PCB board and fixing it. Thus, the problem that the PCB board may be easily offset due to the slight vibration of the docking station 6 during movement, thereby affecting the accurate positioning of the PCB board and further affecting the subsequent processing or detection, is avoided.

[0028] Working principle: through the reciprocating rotation of the rotating shaft 3, the turnover rod 4 is rotated by 180 degrees, when the electric clamping jaw 5 is turned to the side of the docking table 6, the moving block 16 drives the docking table 6 to move towards the fixed frame 1, on the contrary, when the electric clamping jaw 5 is turned away from the docking table 6, the moving block 16 drives the docking table 6 to move away from the fixed frame 1, through the electric clamping jaw 5 clamping the PCB board, the PCB board is turned over to the docking table 6, at this time, the rotating shaft 10 drives the rotating block 9 to rotate, the rotating block 9 drives the calibration block 7 to move under the action of the rotating connection of the pin shaft 22 and the connecting rod 8, the calibration block 7 moves on the upper surface of the docking table 6 to the axis direction of the driving shaft 10, then the calibration block 7 centers and calibrates the PCB board and fixes it.
