Description

Technical Field

[0001] This application relates to the technical field of PCB board production equipment, and more particularly to a board rack type board take-up and unload machine. Background Technology

[0002] PCB board is a printed circuit board that is widely used in various electronic products. It is the substrate that carries electronic components and connecting components. During the production and processing of PCB boards, they need to be put on or taken off. At the beginning of the production line, PCB boards are placed on the conveyor line, and at the end of the production line, they are taken off the production line.

[0003] A related technology discloses a tilting multi-functional board loading and unloading machine, including a frame. From back to front, the inner side of the frame is arranged a conveying mechanism one, a clapping mechanism, a flipping and unloading mechanism, a suction mechanism, and a second conveying mechanism. The clapping mechanism is mounted on the first conveying mechanism, and the suction mechanism is located below the flipping and unloading mechanism. It also includes a product placement rack, which is fixed to a placement plate and positioned in front of the flipping and unloading mechanism. The suction mechanism includes a vertical moving component, a horizontal moving component, and a suction cup component. The output ends of the vertical and horizontal moving components are connected to the suction cup component, which is vertically positioned. In use, the flipping and unloading mechanism flips the PCB board, the suction mechanism first adsorbs the PCB board using the suction cup component, and then moves the PCB board to the product placement rack via the vertical and horizontal moving components, allowing multiple PCB boards to lean against the product placement rack in sequence.

[0004] However, if multiple PCBs are placed close together before the paint is completely dry after printing and painting, the insulating paint on the PCBs can easily stick together, making it inconvenient to load the PCBs. Summary of the Invention

[0005] To reduce PCB board adhesion during the board handling process and facilitate PCB board loading, this application provides a board rack type board handling machine.

[0006] This application provides a plate rack type plate feeding and receiving machine, which adopts the following technical solution:

[0007] A PCB rack-type PCB loading and unloading machine includes a frame, on which a conveyor line, a lifting device, a flipping device, and a horizontal conveyor table are installed. The conveyor line is used to transport PCB racks containing PCBs. The PCB rack includes a base beam, a partition frame, and a support rod. Two base beams are arranged parallel to each other and spaced apart. The partition frame is n-shaped and its two ends rotate on the two base beams. The support rod is located in the middle of the partition frame and is placed higher than the base beam. A lever fixed to the partition frame is also provided below the support rod. The space between the two partition frames is used to place PCBs. A positioning block is fixedly installed on the partition frame, and the two sides of the positioning block are connected to the base beam. When the upper surface of the partition frame abuts, the angle between the partition frame and the horizontal bottom beam is 80-85 degrees; a material-pulling device for moving the lever on the partition frame is provided at the lower part of the conveyor line; the lower part of the lifting device is located on both sides of the conveyor line directly opposite the material-pulling device; the upper part of the lifting device is connected to the flipping device; one side of the flipping device is connected to the upper part of the lifting device, and the other side rotates in the area between horizontal and parallel to the lifting device; the horizontal conveyor table is used to convey the PCB board and is located at the horizontal position of the flipping device, away from the side of the lifting device.

[0008] By adopting the above technical solution, when in use, the PCB board is placed between the two partition frames. The PCB board is supported on the support rod. When it is necessary to unload the PCB board, the two partition frames clamping the PCB board are rotated by the feeding device so that the PCB board is not clamped by the partition frames and is located in the position of the lifting device. At this time, the lifting device transports the PCB board upward. Then, the flipping device turns the PCB board from the inclined state to the horizontal state and transports it to the horizontal conveyor table. Since the PCB board is in an inclined state under the action of the board frame and is separated by the partition frames, the partition frames are automatically opened by the feeding device during the unloading process. This allows the two adjacent PCB boards to be set apart, reducing the adhesion of PCB boards during the unloading process. The automatically opened partition frames facilitate the loading of PCB boards.

[0009] Preferably, conveyor belts are provided on both sides of the conveyor line. The conveyor belts are horizontally arranged, and the upper surface of the conveyor belts is used to convey the plate frame. The material feeding device is provided with fixing devices at the front and rear positions along the conveying direction of the conveyor belt. The distance between the two fixing devices is less than the length of the bottom beam. When the material feeding device moves the separator, the fixing devices fix the bottom beam to the conveyor line.

[0010] By adopting the above technical solution, the upper surface of the conveyor belt is used to convey the plate frame. Fixing devices are set at both the front and rear positions of the feeding device. When the feeding device needs to rotate the separator, the fixing device first fixes the bottom beam on the conveyor line, thereby preventing the plate frame from moving during the feeding device's movement and ensuring the normal opening of the separator.

[0011] Preferably, the feeding device includes a claw, a guide rail, a crank, and a feeding motor. A sliding block is slidably connected to the guide rail, and a conveyor line is rotatably mounted on the upper end of the guide rail. The crank is driven by the feeding motor, and the sliding block is rotatably connected to the crank. The claw is mounted on the upper part of the sliding block, and a sensor for detecting the position of the feeding lever is provided at the position of the feeding device.

[0012] By adopting the above technical solution, the material feeding motor rotates, causing the crank to drive the sliding block to slide along the guide rail. At the same time, it can drive the guide rail to swing, and the pawl installed on the sliding block can swing up and down, so that the material feeding motor can move one separator frame every one revolution.

[0013] Preferably, the lifting device includes a conveyor belt, a rotating wheel, and a first drive motor. A rotating wheel is provided at both ends of the conveyor belt. The conveyor belt is inclined. The rotating wheel at the top of the conveyor belt is coaxially connected to a drive shaft. The first drive motor is used to drive the drive shaft to rotate. A wind chamber is provided in the middle of the conveyor belt. The wind chamber is fixedly connected to the frame. The wind chamber is connected to an exhaust fan. Air holes are opened on the conveyor belt. The wind chamber opens towards the side where the PCB board is placed.

[0014] By adopting the above technical solution, the conveyor belt is equipped with rollers at both ends, and a drive shaft is connected to the first drive motor. The drive shaft drives the rollers to rotate, thereby the conveyor belt transports the PCB board. At the same time, the air holes opened on the conveyor belt can allow the PCB board to be adsorbed on the conveyor belt.

[0015] Preferably, lifting devices are provided at corresponding positions of the two conveyor belts. The lifting device includes an electric cylinder and a gripper installed on the moving part of the electric cylinder. The gripper is used to support the underside of the PCB board, and the electric cylinder is arranged parallel to the conveyor belt.

[0016] By adopting the above technical solution, the lifting device includes an electric cylinder and a gripper. The gripper is located on the underside of the PCB board. During the process of the electric cylinder driving the gripper to move, the gripper maintains support for the PCB board so that the PCB board can move on the conveyor belt.

[0017] Preferably, a roller frame is provided on the side of the two conveyor belts that are far apart from each other. Multiple rollers are arranged in sequence on the roller frame. The arrangement direction of the rollers is parallel to the conveying direction of the conveyor belts. When the PCB board is located on the roller frame, the PCB board is attached to the surface of the conveyor belt.

[0018] By adopting the above technical solution, the rollers set on the roller frame are used to support the PCB, so that the roller frame limits the distance between the PCB and the conveyor belt, so as to prevent the PCB from sticking too tightly on the conveyor belt and reduce the adhesion of the PCB on the conveyor belt.

[0019] Preferably, the flipping device includes a flipping platform and a second drive motor for driving the flipping platform to rotate. One end of the flipping platform extends to the drive shaft, and a bearing seat is rotatably mounted on the drive shaft. The bearing seat is fixed on the flipping platform, and the second drive motor is used to drive the bearing seat to rotate.

[0020] By adopting the above technical solution, the second drive motor is connected to the bearing housing, so that the second drive motor rotates the bearing housing, and the bearing housing is fixed on the tilting table, so that the tilting table rotates to the required angle under the action of the second drive motor.

[0021] Preferably, a fixed plate is fixedly installed on the flip plate platform, and a rotary clamping angle cylinder is installed on the fixed plate. A stop bar is fixedly installed at the end of the rotary clamping angle cylinder. When one end of the stop bar is rotated to a position perpendicular to the PCB board by the rotary clamping angle cylinder, it is used to block the side of the PCB board.

[0022] By adopting the above technical solution, a rotary clamping angle cylinder is fixedly installed on the fixed plate. The rotary clamping angle cylinder can abut against one side of the PCB board and automatically move away from the PCB board when it moves away from one side of the PCB board. By setting the stop bar, the position of the PCB board can be positioned, and the PCB board can be prevented from falling off.

[0023] Preferably, the horizontal conveyor table includes a plurality of spaced conveyor rollers, and an adjustment device is provided on the horizontal conveyor table. The adjustment device includes two opposing push plates and a slide bar fixed on the frame. A slider is slidably connected to the slide bar, the push plates are fixed on the slider, and the two sliders are connected to a driving component for driving the sliders to move closer or further apart.

[0024] By adopting the above technical solution, the adjustment device includes two push plates arranged opposite each other. The push plates move closer to each other under the action of the driving component. When a PCB board is placed between the two push plates, the push plates abut against the PCB board to adjust the position of the PCB board so that the PCB is neatly stacked.

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a plate rack type plate take-up and put-down machine, see reference. Figure 1 and Figure 2The system includes a frame 1, a conveyor line 2 at the bottom of the frame 1, a board rack 3 on the conveyor line 2, and a board rack 3 for placing PCB boards. The number of PCB boards on each board rack 3 can be set from 15 to 30 as needed, and in this embodiment, it is 19. A lifting device 8 is installed 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 upward. A flipping device 5 is connected to the upper part of the lifting device 8. The flipping device 5 is used to flip the PCB board. A horizontal conveyor table 6 is installed on the side of the flipping device 5 away from the lifting device 8. The horizontal conveyor table 6 is used to horizontally convey the PCB board. The flipping device 5 is used to transition the PCB board between the lifting device 8 and the horizontal conveyor table 6. That is, when the board is being collected, when the PCB board is conveyed from the horizontal conveyor table 6 to the lifting device 8, the flipping device 5 rotates the horizontally conveyed PCB board to a position parallel to the lifting device 8. When the board is being released, the flipping device 5 first rotates to a position parallel to the lifting device 8. Then the PCB board on the lifting device 8 moves to the flipping device 5. The flipping device 5 then drives the PCB board to rotate to a horizontal position and then conveys it to the horizontal conveyor table 6.

[0035] refer to Figure 3 The horizontal conveyor table 6 includes multiple spaced conveyor rollers 61, which 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 transferred by the rotation of the conveyor rollers 61. An adjustment device 7 is provided at the position of the horizontal conveyor table 6 to adjust the position of the PCB board so that the position of the PCB board entering the horizontal conveyor table 6 is consistent, so as to ensure the accuracy of board placement and board collection. The adjustment device 7 includes two opposing push plates 71 and a slide rod 72 fixed on the frame 1. A slider 73 is provided on the slide rod 72, and the push plates 71 are fixed on the slider 73. The push plates 71 are perpendicular to the conveyor roller 61, and the slide rod 72 is parallel to the conveyor roller 61. When the slider 73 is slidably connected to the slide rod 72 and slides along the slide rod 72, the two push plates 71 move closer to the middle from both ends of the conveyor roller 61. A drive component 74 for driving the two sliders 73 to move closer or further apart is fixed on the frame 1. In this embodiment, the drive component 74 includes a motor 741 and a belt 742. Both ends of the belt 742 are provided with support wheels. The output shaft of the motor 741 is coaxially fixedly connected to one of the support wheels. The transmission direction of the belt 742 can be parallel to the conveyor roller 61, so that the two sliders 73 are fixed at both ends of the belt 742 and located on both sides of the support wheels, so that the belt 742 drives the two sliders 73 to move simultaneously during rotation. When the two push plates 71 come close to each other, they can clamp the PCB board and position it in the middle of the conveyor roller 61.

[0036] refer to Figure 2 and Figure 4 The lifting device 8 includes a conveyor belt 81, a rotating wheel 82, and a first drive 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 inclined from top to bottom towards the side away from the flip-plate device 5, so that the PCB board being conveyed on the conveyor belt 81 can rest against it to prevent tilting. The horizontal inclination angle of the conveyor belt 81 is selected as 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 and is connected to an exhaust fan 86. Multiple air holes 85 are spaced apart on the conveyor belt 81, and the wind chamber 84 opens towards the side facing the PCB board. The exhaust fan 86 can generate suction at the air holes 85, allowing the PCB board to be further adhered to the conveyor belt 81, thereby further improving the safety of the PCB. The first drive motor 83 is connected to a drive shaft 87, which is coaxially and fixedly connected to two pulleys 82 at the upper ends of the two conveyor belts 81. When the first drive motor 83 is working, the drive shaft 87 can drive the two conveyor belts 81 to rotate simultaneously. The two ends of the drive shaft 87 are rotatably connected to the frame 1. A coupling can be provided between the first drive motor 83 and the drive shaft 87, or they can rotate through a belt 742.

[0037] Roller frames 88 are also provided on the outer side of the two conveyor belts 81. Multiple rollers are arranged in sequence on the roller frames 88, and the arrangement direction of the rollers is parallel to the conveying direction of the conveyor belts 81. When the PCB board is conveyed by the two conveyor belts 81, the rollers on the two roller frames 88 support the two sides of the PCB board. The roller frames 88 are used to block the sides of the PCB board to prevent the PCB board from deviating. At the same time, the PCB board is attached to the surface of the conveyor belts 81 under the support of the roller frames 88, so as to prevent the conveyor belts 81, the air chamber 84 and the PCB board from being directly sucked into a tight state under the action of the exhaust fan 86, which would cause wear on the conveyor belts 81 or the PCB board to stick to the conveyor belts 81. The conveyor belts 81 are used to maintain the tilted state of the PCB board without generating a large squeezing force.

[0038] Lifting devices 9 are installed at corresponding positions on both conveyor belts 81. Each lifting device 9 includes an electric cylinder 91 and a gripper 92 installed on 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 positioned on the lower side of the PCB board and supports it. The electric cylinder 91 and the conveyor belt 81 move at the same speed, 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 PCB board in an inclined state and at the same time prevent the PCB board from sliding relative to the conveyor belt 81, which would cause damage to the PCB board.

[0039] The flipping device 5 includes a flipping platform 51 and a second drive motor 52 for rotating the flipping platform 51. One end of the flipping platform 51 extends to the position of the drive shaft 87, and a bearing seat 53 is rotatably mounted on the drive shaft 87. The bearing seat 53 is fixed on the flipping platform 51, and 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 drives the flipping platform 51 to rotate, so that the flipping platform 51 rotates between a horizontal position and a position parallel to the conveyor belt 81. When the flipping platform 51 rotates to the horizontal position, the flipping platform 51 is on one side of the horizontal conveyor table 6. When the flipping platform 51 rotates to be parallel to the conveyor belt 81, the flipping platform 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 flipping platform 51 from the conveyor belt 81. A fixing plate 54 is fixedly installed on the side of the flipping table 51 near the conveyor belt 81. A rotary clamping angle cylinder is installed on the fixing plate 54. The rotary clamping angle cylinder can be of model SRC25-90L or SRC25-90R. In this embodiment, two are used. The rotary clamping angle cylinder can extend and retract during the 90-degree rotation. A stop bar 55 is fixedly installed at the end of the rotary clamping angle cylinder. One end of the stop bar 55 is fixed to the rotary clamping angle cylinder, and the other end is used to block the side of the PCB board. When the PCB board is being collected, it is first moved horizontally to a position where it abuts against the baffle 55. Then, when the flipping table 51 rotates to a position parallel to the conveyor belt 81, the baffle 55 rotates and offsets the PCB board under the action of the rotary clamping angle cylinder, so that the PCB board can be stably transferred onto the conveyor belt 81. When the board is being unloaded, as the PCB board moves onto the flipping table 51 along with the conveyor belt 81, the baffle 55 rotates 90 degrees under the action of the rotary clamping angle cylinder and blocks the underside of the PCB board to prevent the PCB board from falling off after being detached from the gripper 92.

[0040] refer to Figure 5The board frame 3 includes a base beam 31, a partition frame 32, and a support rod 33. Two base beams 31 are provided, arranged parallel to each other. The partition frame 32 is n-shaped, and its two ends are rotatably connected to the two base beams 31 respectively. A positioning block 34 is provided above each partition frame 32, and is fixed to the partition frame 32. When the sides of the positioning block 34 abut against the upper surface of the base beam 31, the partition frame 32 rotates to an inclined state. Under the action of the positioning block 34, the inclination angle of the partition frame 32 is controlled at 80-85 degrees to prevent excessive inclination angle, which could cause excessive pressure between the PCB board and the partition frame 32 and damage the PCB board. The support rod 33 is located inside the partition frame 32 and parallel to the base beam 31. The support rod 33 is fixed to the base beam 31 at both ends by brackets. The position of the support rod 33 is higher than the base beam 31, so that the side of the PCB board placed between the two partition frames 32 rests on the support rod 33. Meanwhile, two positioning blocks 34 located on the same partition 32 are fixedly equipped with levers 35. The levers 35 can easily rotate the partition 32, increasing the distance between the two partitions 32 with opposite tilt directions, making it easier to place or remove the PCB board.

[0041] refer to Figure 6 and Figure 7 Conveyor belts 21 are installed on both sides of the conveyor line 2. The conveyor belts 21 are horizontally arranged and are the existing structure used to transport items. The upper surface of the conveyor belts 21 is used to transport the board frame 3. When the board frame 3 moves onto the conveyor belts 21, it will move under the action of the conveyor belts 21 as they rotate. A material-pushing device 10 is fixedly installed on the conveyor line 2. The material-pushing device 10 is located directly opposite the lower part of the lifting device 8. The material-pushing device 10 pushes the separators 32 on the conveyor line 2, causing multiple separators 32 to rotate in sequence, which facilitates the removal or retraction of PCB boards. Fixing devices 11 are arranged at positions before and after the material-pushing device 10 along the conveying direction of the conveyor belt 21. The distance between two fixing devices 11 is less than the length of the bottom beam 31. The fixing devices 11 are used to fix the board frame 3 to prevent the board frame 3 from moving along the conveyor belt 21 when the material-pushing device 10 pushes the separators 32.

[0042] The fixing device 11 includes a cylinder 111 and a clamping block 112. The cylinder 111 is fixed to the conveyor line 2 by the frame. The cylinder 111 does not move with the conveyor belt 21. The direction of movement 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. This allows the clamping block 112 to abut against the side wall of the bottom beam 31 when the cylinder 111 extends, thereby fixing the plate frame 3 relative to the conveyor line 2 and preventing it from moving with the conveyor belt 21.

[0043] The feeding device 10 includes a pawl 101, a guide rail 102, a crank 103, and a feeding motor 104. The crank 103 is driven by the feeding motor 104. A coupling or a belt 742 can be provided between the crank 103 and the feeding motor 104 for rotation. A sliding block 105 is rotatably connected to the crank 103 and is slidably connected to the guide rail 102. The pawl 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 pawl 101 is located above the sliding block 105. When the crank 103 rotates, the sliding block 105 slides along the guide rail 102 and drives the crank 103 to rotate. The guide rail 102 rotates, causing the claw 101 to move up and down while swinging. A sensor 106 is fixedly installed at the position of the feeding 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 feeding motor 104 to rotate one revolution, thereby completing the rotation of one separator 32. Then the fixing device 11 releases the board frame 3, and the board frame 3 continues to move to the position of one separator 32 and stops. The feeding device 10 then completes one feeding cycle, thereby releasing multiple PCB boards from the board frame 3 in sequence.

[0044] The working process of this application embodiment:

[0045] During board collection, the pawl 101 rotates one of the separator frames 32, increasing the distance between the two separator frames 32. Simultaneously, the flipping device 5 rotates the PCB board to an inclined position and guides it onto the conveyor belt 81. The PCB board then moves along the conveyor belt 81 between the two oppositely inclined separator frames 32, completing the board collection process. During board placement, the pawl 101 moves the separator frame 32, and the exhaust fan 86 causes the PCB board to rest against the conveyor belt 81. The separator frame 32 passes between the two conveyor belts 81, and then the gripper 92 lifts the PCB board from below onto the flipping device 5.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
