Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a pushing device for a PCB board feeding machine. Background Technology

[0002] A PCB, or printed circuit board, is a component that provides electrical connections for electronic components. Automatic PCB feeders are primarily used to transport PCBs one by one onto the production line. Existing automatic PCB feeders offer various feeding methods, including vacuum suction, drop feeding, and push-feeding.

[0003] In existing PCB board feeding machines, the pushing device is usually fixed in size, while the size of different PCB boards is not consistent. This can easily cause the PCB board to tilt or wobble when being pushed, affecting the connection between the PCB board and the material handling or production equipment, making it inconvenient to use. Therefore, we propose a pushing device for a PCB board feeding machine to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the size of the pushing device is usually fixed during actual use, while the size of different PCB boards varies. This leads to the PCB board tilting or shaking when being pushed, affecting the connection between the PCB board and the material handling or production equipment, making it inconvenient to use. Therefore, this invention proposes a pushing device for a PCB board feeding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pushing device for a PCB board feeder includes a base, and the pushing device for the PCB board feeder further includes: The adjustment motor and the housing are fixedly connected, with the adjustment motor fixedly connected to the top of the base and the housing fixedly connected to the top of the output shaft of the adjustment motor; The system includes a control motor, a lever, a horizontal plate, and a conveyor plate. The control motor is fixedly connected to the bottom inner wall of the housing. The lever is fixedly connected to the top of the control motor's output shaft. The horizontal plate is slidably connected to the inner wall of the housing, and the bottom of the horizontal plate is slidably connected to the top of the lever. The conveyor plate is fixedly connected to the left side of the horizontal plate, and the left side of the conveyor plate extends to the outside of the housing. The electric actuator and clamping plates are provided. The electric actuator is fixedly connected to the top of the conveyor plate, and there are two clamping plates, which are symmetrically and movably connected to the top of the conveyor plate. A fixing mechanism is provided on the top of the conveyor plate and is connected to the clamping plate.

[0006] As a preferred embodiment of this utility model, the fixing mechanism includes: a transmission block, two pulleys, two sliding plates, two transmission rods, and two connecting rods; The transmission block is slidably connected to the top of the conveyor plate, and the right side of the transmission block is fixedly connected to the left side of the electric push rod. Two pulleys are rotatably connected to the front and rear sides of the transmission block, respectively. Two slide plates are symmetrically slidably connected to the top of the conveyor plate. Two transmission rods are rotatably connected to the top of the corresponding slide plates. Two connecting rods are symmetrically slidably connected to the top of the conveyor plate. The sides of the two connecting rods that are far apart from each other are fixedly connected to the sides of the two clamping plates that are close to each other. The tops of the two connecting rods are rotatably connected to the bottoms of the corresponding transmission rods.

[0007] In a preferred embodiment of this utility model, a pusher plate is fixedly connected to the left side of the transmission block, and the bottom of the pusher plate is slidably connected to the top of the conveyor plate.

[0008] As a preferred embodiment of this utility model, the inner wall of the outer shell is symmetrically and fixedly connected with two limiting rods, both of which penetrate the horizontal plate.

[0009] As a preferred embodiment of this utility model, the top of the conveying plate is symmetrically fixedly connected with two support plates, and the left sides of the two support plates are slidably connected to the corresponding clamps and connecting rods.

[0010] As a preferred embodiment of this utility model, the top of the conveying plate is symmetrically and fixedly connected with a guide plate, and the right side of the guide plate is fixedly connected to the left side of the support plate. The guide plate has a hollow structure, and the inner wall of the guide plate is slidably connected to the outer wall of the connecting rod.

[0011] As a preferred embodiment of this utility model, a return spring is fixedly connected to the side of each of the two guide plates that is far apart from each other, and the side of each of the two return springs that is far apart from each other is fixedly connected to the side of each of the two clamping plates that is close to each other.

[0012] Beneficial effects: By adjusting the overall rotation of the motor-driven housing, the pushing position of the conveyor plate can be flexibly adjusted. The motor operation is controlled to drive the lever to rotate. The lever, through its sliding connection with the horizontal plate, converts its horizontal reciprocating motion into a stable linear feeding action of the horizontal plate and the conveyor plate fixed on it. During the pushing process, the electric push rod can drive the transmission block to move. The pulleys on both sides of the transmission block push the two slide plates to slide towards each other. Then, through the transmission rod, the connecting rod and the clamping plate overcome the elasticity of the return spring and clamp the PCB board synchronously, so that the PCB board remains stable during the pushing process. This invention achieves integrated collaborative operation of adjustable PCB board pushing angle and precise clamping and fixing during transit through a simple structure, significantly improving the positioning accuracy, stability and automation of PCB board conveying, and has good practicality and convenience.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1 Reference Figure 1-4 A pushing device for a PCB board feeding machine includes a base 1, and the pushing device for the PCB board feeding machine further includes: Adjust the motor 2 and the housing 3. The motor 2 is fixedly connected to the top of the base 1, and the housing 3 is fixedly connected to the top of the output shaft of the motor 2. The motor 2 can easily drive the housing 3 to rotate, thereby rotating the conveyor plate 7 and adjusting the rotation direction of the PCB board. The system includes a control motor 4, a lever 5, a horizontal plate 6, and a conveyor plate 7. The control motor 4 is fixedly connected to the bottom inner wall of the housing 3. The lever 5 is fixedly connected to the top of the output shaft of the control motor 4. The horizontal plate 6 is slidably connected to the inner wall of the housing 3, and the bottom of the horizontal plate 6 is slidably connected to the top of the lever 5. The conveyor plate 7 is fixedly connected to the left side of the horizontal plate 6, and the left side of the conveyor plate 7 extends to the outside of the housing 3. The control motor 4 can easily drive the lever 5 to rotate, and the lever 5 can easily push the horizontal plate 6 to move, so that the conveyor plate 7 can drive the PCB board to move laterally. The electric push rod 8 is fixedly connected to the top of the conveyor plate 7. There are two clamping plates 16, which are symmetrically and movably connected to the top of the conveyor plate 7. A fixing mechanism is provided on the top of the conveyor plate 7 and is connected to the clamping plate 16.

[0017] In order to facilitate the movement of the connecting rod 14 to move the clamping plate 16 and thus fix the PCB board, the fixing mechanism includes: transmission block 9, two pulleys 11, two sliding plates 12, two transmission rods 13 and two connecting rods 14; The transmission block 9 is slidably connected to the top of the conveyor plate 7, and the right side of the transmission block 9 is fixedly connected to the left side of the electric push rod 8. Two pulleys 11 are rotatably connected to the front and rear sides of the transmission block 9 respectively. Two slide plates 12 are symmetrically slidably connected to the top of the conveyor plate 7. Two transmission rods 13 are rotatably connected to the top of the corresponding slide plates 12. Two connecting rods 14 are symmetrically slidably connected to the top of the conveyor plate 7. The sides of the two connecting rods 14 that are far apart from each other are fixedly connected to the sides of the two clamping plates 16 that are close to each other. The tops of the two connecting rods 14 are rotatably connected to the bottoms of the corresponding transmission rods 13.

[0018] To facilitate the movement of the PCB board for pushing, a push plate 10 is fixedly connected to the left side of the transmission block 9, and the bottom of the push plate 10 is slidably connected to the top of the conveyor plate 7.

[0019] To facilitate the limiting of the horizontal plate 6 and ensure its stable lateral movement, two limiting rods are symmetrically fixed to the inner wall of the outer shell 3, and both limiting rods penetrate the horizontal plate 6.

[0020] In order to support and limit the clamping plate 16 and the connecting rod 14 and make them move stably, the top of the conveying plate 7 is symmetrically fixedly connected with two support plates 15. The left side of the two support plates 15 is slidably connected to the corresponding clamping plate 16 and connecting rod 14.

[0021] To facilitate the stable back-and-forth movement of the connecting rod 14, a guide plate 18 is symmetrically fixedly connected to the top of the conveying plate 7, and the right side of the guide plate 18 is fixedly connected to the left side of the support plate 15. The guide plate 18 has a hollow structure, and the inner wall of the guide plate 18 is slidably connected to the outer wall of the connecting rod 14.

[0022] To facilitate the automatic reset of the clamping plate 16, a reset spring 17 is fixedly connected to the side of each of the two guide plates 18 that is far apart from each other, and the side of each of the two reset springs 17 that is far apart from each other is fixedly connected to the side of each of the two clamping plates 16 that is close to each other.

[0023] The working principle of this utility model is as follows: When in use, the base 1 is installed in a suitable position, and the PCB board can then be placed on top of the conveyor plate 7. By starting the regulating motor 2, the output shaft of the regulating motor 2 rotates, which drives the outer casing 3 to rotate. The rotation of the outer casing 3 drives the conveyor plate 7 to rotate, thereby rotating the PCB board and adjusting the conveying angle of the PCB board. By starting the control motor 4, the output shaft of the control motor 4 rotates, which causes the lever 5 to rotate. When the lever 5 rotates, it pushes the horizontal plate 6 to move laterally. When the horizontal plate 6 moves, it drives the conveyor plate 7 to move to the left, thus pushing the PCB board laterally. The movement distance of the conveyor plate 7 is controlled by controlling the rotation of the output shaft of the control motor 4. By starting the electric push rod 8, its retraction drives the transmission block 9 and the push plate 10 to move laterally. Simultaneously, the movement of the transmission block 9 drives the pulley 11 to move to the right. The movement of the pulley 11 pushes the slide plate 12 laterally, which in turn pushes the transmission rod 13. Moving the transmission rod 13 pushes the connecting rod 14, causing the two connecting rods 14 to move closer to each other and move the two clamping plates 16 closer to each other. The movement of the clamping plates 16 compresses the return spring 17. The movement of the two clamping plates 16 closer to each other clamps and fixes the PCB board, thus keeping the PCB board stable during pushing. When the conveyor plate 7 moves the PCB board to the appropriate position, the electric push rod 8 is activated. The electric push rod 8 extends and moves the push plate 10 to the left. At this time, the pulley 11 moves and disengages from the slide plate 12. Simultaneously, the return spring 17 loses its restraint and pushes the two clamping plates 16 to move further away from each other, disengaging from the PCB board, thus unlocking the PCB board. The electric push rod 8 continues to extend and moves the push plate 10, pushing the PCB board laterally from the conveyor plate 7 until it disengages from the conveyor plate 7, thus achieving the effect of conveying the PCB board. By controlling the retraction distance of the electric push rod 8, PCB boards of different sizes can be fixed, which has good practicality and convenience.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
