A lifting device 8 is provided on the path of the conveyor line 2. The lower part of the lifting device 8 is connected to the conveyor line 2. The lifting device 8 is used to move the PCB board on the conveyor line 2 upwards. A flip device 5 is connected to the upper part of the lifting device 8. The flip device 5 is used to flip the PCB board. A horizontal conveying table 6 is provided on the side of the flip device 5 away from the lifting device 8. The horizontal conveying table 6 is used to horizontally convey the PCB board. The flip device 5 is used to transfer the PCB board between the lifting device 8 and the horizontal conveying table 6. That is, when collecting the board, when the PCB board is conveyed from the horizontal conveying table 6 to the lifting device 8, the flip device 5 rotates the PCB board horizontally conveyed to the flip device 5 to a position parallel to the lifting device 8. When placing the board, the flip device 5 first rotates to a position parallel to the lifting device 8, and then the PCB board on the lifting device 8 will move to the flip device 5, and then the flip device 5 drives the PCB board to rotate to a horizontal position, and then it is conveyed to the horizontal conveying table 6.

[0028] refer to Figure 3 The horizontal conveyor 6 includes a plurality of conveyor rollers 61 arranged at intervals. The plurality of conveyor rollers 61 are parallel and perpendicular to the conveying direction of the PCB board. Both ends of the conveyor rollers 61 are rotatably connected to the frame 1. The PCB board is placed on the upper part of the conveyor rollers 61 and is transmitted by the rotation of the conveyor rollers 61. An adjustment device 7 is provided at the position of the horizontal conveyor 6. The adjustment device 7 is used to adjust the position of the PCB board so that the position of the PCB board entering the horizontal conveyor 6 is consistent to ensure the accuracy of placing and collecting the board. The adjusting device 7 includes two push plates 71 arranged opposite to each other and a slide bar 72 fixed on the frame 1. A slide bar 73 is arranged on the slide bar 72. The push plate 71 is fixed on the slide bar 73. The push plate 71 is arranged perpendicular to the conveying roller 61. The slide bar 72 is parallel to the conveying roller 61. When the slide bar 73 is slidably connected to the slide bar 72 and slides along the slide bar 72, the two push plates 71 move toward the middle from the two ends of the conveying roller 61. A driving member 74 is fixed on the frame 1 for driving the two slide blocks 73 to move relatively close to or away from each other. The driving member 74 in this embodiment includes a motor 741 and a belt 742. Support wheels are arranged at both ends of the belt 742. The output shaft of the motor 741 is coaxially fixedly connected to a support wheel. The transmission direction of the belt 742 can be parallel to the conveying roller 61, so that the two slide blocks 73 are respectively fixed at the two ends of the belt 742 and are located on both sides of the support wheel, so that the two slide blocks 73 are driven to move simultaneously during the rotation of the belt 742. When the two push plates 71 are moved closer to each other, the two push plates 71 can sandwich the PCB and be positioned at the middle of the conveying roller 61 .

[0029] refer to Figure 2 and Figure 4The lifting device 8 includes a conveyor belt 81, a rotating wheel 82 and a first driving motor 83. A rotating wheel 82 is provided at each end of the conveyor belt 81 for support. Two conveyor belts 81 are symmetrically arranged on both sides of the conveyor line 2. The conveyor belt 81 is tilted from top to bottom toward the side away from the flap device 5, so that the PCB board on the conveyor belt 81 can lean on the conveyor belt 81 to avoid tilting. The horizontal tilt angle of the conveyor belt 81 is selected to be 80-85 degrees. A wind chamber 84 is also provided in the middle of the conveyor belt 81. The wind chamber 84 is fixedly connected to the frame 1. The wind chamber 84 is connected to the exhaust fan 86. A plurality of air holes 85 are spaced apart on the conveyor belt 81, and the wind chamber 84 opens toward one side of the PCB board. The exhaust fan 86 can generate suction at the position of the air hole 85, so that the PCB board can be further adsorbed on the conveyor belt 81, thereby further improving the safety of the PCB. The first drive motor 83 is connected to a driving shaft 87, which is coaxially fixedly connected to the two rotating wheels 82 at the upper ends of the two conveyor belts 81. When the first drive motor 83 is working, the driving shaft 87 can drive the two conveyor belts 81 to rotate simultaneously. Both ends of the driving shaft 87 are rotatably connected to the frame 1. A coupling can be set between the first drive motor 83 and the driving shaft 87 or the belt 742 can be used for rotation.

[0030] A roller rack 88 is also provided on the outer side of the two conveyor belts 81. A plurality of rollers are arranged on the roller rack 88 in sequence, and the arrangement direction of the rollers is parallel to the conveying direction of the conveyor belt 81. When the PCB board is conveyed by the two conveyor belts 81, the rollers on the two roller racks 88 support both sides of the PCB board. The roller rack 88 is used to block the side edges of the PCB board to prevent the PCB board from running off the track. At the same time, the PCB board is attached to the surface of the conveyor belt 81 under the support of the roller rack 88, so as to prevent the conveyor belt 81, the air chamber 84 and the PCB board from being directly sucked into a state of close contact with each other under the action of the exhaust fan 86, thereby causing the conveyor belt 81 to be worn or the PCB board to be attached to the conveyor belt 81, so that the conveyor belt 81 is used to maintain the inclined state of the PCB board without generating a large extrusion force.

[0031] Lifting devices 9 are provided at positions corresponding to the two conveyor belts 81. The lifting devices 9 include an electric cylinder 91 and a gripper 92 installed at the moving part of the electric cylinder 91. The conveying direction of the electric cylinder 91 is parallel to the conveyor belt 81. The gripper 92 is driven by the electric cylinder 91 and moves along the output direction of the electric cylinder 91. The gripper 92 extends to the side of the conveyor belt 81 where the PCB board is placed, so that the gripper 92 is at the lower side of the PCB board to support the PCB board. The movement speeds of the electric cylinder 91 and the conveyor belt 81 are the same, so that the gripper 92 connected to the electric cylinder 91 can drive the PCB board to move along the conveyor belt 81. The conveyor belt 81 is used to maintain the inclined state of the PCB board and prevent the PCB board and the conveyor belt 81 from sliding relative to each other to avoid damage to the PCB board.

[0032] The flap device 5 includes a flap table 51 and a second drive motor 52 for driving the flap table 51 to rotate. One end of the flap table 51 extends to the position of the driving shaft 87, and a bearing seat 53 is rotatably arranged on the driving shaft 87. The bearing seat 53 is fixed on the flap table 51 so that the bearing seat 53 is driven by the second drive motor 52. The bearing seat 53 and the second drive motor 52 can be connected by a belt 742 or a coupling. The second drive motor 52 is a servo motor. When the second drive motor 52 is working, it is used to drive the flap table 51 to rotate, so that the flap table 51 rotates between the horizontal position and the position parallel to the conveyor belt 81. When the flap table 51 rotates to the horizontal position, the flap table 51 is on one side of the horizontal conveyor table 6. When the flap table 51 rotates to be parallel to the conveyor belt 81, the flap table 51 is at the end of the conveyor belt 81 and is used to extend the conveyor belt 81, so that the PCB board on the conveyor belt 81 can enter the flap table 51 from the conveyor belt 81. A fixed plate 54 is fixedly arranged on one side of the plate turning platform 51 close to the conveyor belt 81, and a rotary clamping angle cylinder is installed on the fixed plate 54. The rotary clamping angle cylinder can be of SRC25-90L or SRC25-90R. Two of them are used at the same time in this embodiment. The rotary clamping angle cylinder can be extended and retracted during the 90-degree rotation. A stop bar 55 is fixedly arranged at the end of the rotary clamping angle cylinder. One end of the stop bar 55 is fixed on the rotary clamping angle cylinder, and the other end is used to block the side of the PCB board. When collecting the board, the PCB board first moves horizontally to a position abutting against the baffle bar 55, and then when the turning table 51 turns to a position parallel to the conveyor belt 81, the baffle bar 55 rotates to stagger the PCB board under the action of the rotating clamping angle cylinder, so that the PCB board can be stably transferred to the conveyor belt 81. When placing the board, when the PCB board moves to the turning table 51 along with the conveyor belt 81, the baffle bar 55 rotates 90 degrees under the action of the rotating clamping angle cylinder and blocks the lower side of the PCB board to prevent the PCB board from falling off after detaching from the gripper 92.

[0033] refer to Figure 5The board frame 3 includes a bottom beam 31, a partition frame 32 and a support rod 33. The bottom beam 31 is provided with two and arranged in parallel and spaced apart. The partition frame 32 is n-shaped, and the two ends of the partition frame 32 are respectively connected to the two bottom beams 31 for rotation. A positioning block 34 is provided above the partition frame 32 and corresponds to each partition frame 32. The positioning block 34 is fixed on the partition frame 32. When the two sides of the positioning block 34 abut against the upper surface of the bottom beam 31, the partition frame 32 rotates to a tilted state. Under the action of the positioning block 34, the tilt angle of the partition frame 32 is controlled at 80-85 degrees to avoid excessive tilt angle, which causes excessive pressure between the PCB board and the partition frame 32 and damage to the PCB board. The support rod 33 is located inside the partition frame 32 and is arranged parallel to the bottom beam 31. The support rod 33 is fixed to the bottom beam 31 at both ends of the bottom beam 31 through a bracket. The position of the support rod 33 is higher than the bottom beam 31, so that the side of the PCB board placed between the two partition frames 32 is supported on the support rod 33. At the same time, two positioning blocks 34 on the same partition frame 32 are fixedly provided with a lever 35, which can conveniently rotate the partition frame 32 to increase the distance between the two partition frames 32 with opposite tilt directions, making it convenient to place or take out the PCB board.

[0034] refer to Figure 6 and Figure 7 , conveyor belts 21 are arranged on both sides of the conveyor line 2, and the conveyor belts 21 are arranged horizontally. The conveyor belts 21 are existing structures for conveying articles. The upper surface of the conveyor belts 21 is used to convey the plate racks 3. When the plate racks 3 move onto the conveyor belts 21, as the conveyor belts 21 rotate, the plate racks 3 will move under the action of the conveyor belts 21. A material-dispensing device 10 is fixedly arranged on the conveyor line 2. The material-dispensing device 10 is located at a position directly opposite to the lower part of the lifting device 8, so that the material-dispensing device 10 can shift the partition frames 32 on the conveyor line 2, so that multiple partition frames 32 can be rotated in sequence, which is convenient for taking out or retracting the PCB board. Fixing devices 11 are arranged at the front and rear positions of the material-dispensing device 10 along the conveying direction of the conveyor belt 21. The distance between the two fixing devices 11 is less than the length of the bottom beam 31. The fixing devices 11 are used to fix the plate racks 3 to prevent the plate racks 3 from moving along the conveyor belt 21 when the material-dispensing device 10 shifts the partition frames 32.

[0035] The fixing device 11 includes a cylinder 111 and a clamping block 112. The cylinder 111 is fixed to the conveyor line 2 through a frame. The cylinder 111 does not move with the conveyor belt 21. The moving direction of the output end of the cylinder 111 is perpendicular to the conveying direction of the conveyor belt 21. The clamping block 112 is fixed to the output end of the cylinder 111, and the height of the clamping block 112 is the same as the height of the bottom beam 31 placed on the conveyor belt 21. When the cylinder 111 is extended, the clamping block 112 abuts against the side wall of the bottom beam 31, thereby fixing the plate rack 3 relative to the conveyor line 2 and not moving with the conveyor belt 21.

[0036] The material dispensing device 10 includes a finger 101, a guide rail 102, a crank 103 and a material dispensing motor 104. The crank 103 is driven by the material dispensing motor 104. A coupling can be set between the crank 103 and the material dispensing motor 104 or the belt 742 can be used to rotate. A sliding block 105 is rotatably connected to the crank 103. The sliding block 105 is slidably connected to the guide rail 102. The finger 101 is fixed to the sliding block 105, and the upper part of the guide rail 102 is rotatably connected to the conveyor line 2. The finger 101 is located at the upper part of the sliding block 105. When the crank 103 rotates, the sliding block 105 slides along the guide rail 102 and drives The guide rail 102 rotates, causing the finger 101 to move up and down and swing at the same time. A sensor 106 is fixedly provided at the position of the material dispensing device 10. The sensor 106 is used to detect the position of the lever 35. When a lever 35 is directly above the sensor 106, the sensor 106 detects a signal, and the processor controls the material dispensing motor 104 to rotate one circle, thereby completing the rotation of a partition frame 32. Then the fixing device 11 releases the board rack 3, and the board rack 3 continues to move to the position of a partition frame 32 and stops. The material dispensing device 10 completes a material dispensing, thereby releasing multiple PCB boards on the board rack 3 in sequence.

[0037] The working process of the embodiment of this application: When collecting the board, the pusher claw 101 rotates one of the partition frames 32, and the distance between the two partition frames 32 increases. At the same time, the flipping device 5 rotates the PCB to an inclined state and enters the conveyor belt 81. The PCB enters between the two partition frames 32 inclined in opposite directions along the conveyor belt 81 to complete the board collection. When placing the board, the pusher claw 101 moves the partition frame 32 and, under the action of the exhaust fan 86, the PCB is placed against the conveyor belt 81. The partition frame 32 passes between the two conveyor belts 81, and then the gripper 92 lifts the PCB from the bottom of the PCB to the flipping device 5.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
