[0002] PCB boards are important components used to connect and support electronic components in electronic devices. PCB boards form circuit networks by laying conductive paths on insulating substrates, thereby achieving electrical connections between electronic components. During the PCB board production process, a blanking and positioning structure is usually used to collect and transport the processed PCB boards. In the initial state, the interception plate intercepts the PCB boards conveyed to the conveying assembly, and then the dual-axis motor drives the lead screw to rotate, thereby driving the board receiving clamp to move inward to center the PCB board on the conveying assembly. The board receiving clamp is then reset, and the interception plate is reset downward, and the conveying assembly continues to convey the PCB board to the left. When the board receiving clamp moves inward to contact the PCB board and center it, the contact force between the board receiving clamp and the PCB board may be too large, causing damage to the PCB board. In addition, during the production process, the dual-axis motor or other equipment may malfunction, causing the board receiving clamp to continue clamping the PCB board, which may also cause damage to the PCB board.

[0003] In order to solve the above problems, a PCB blanking and positioning structure is developed. Utility Model Content

[0021] like Figure 1-Figure 5 As shown, it also includes a limit plate 11, and two limit plates 11 are slidably connected between the left and right sides of the guide rod 6. The limit plates 11 are all in an inverted "J" shape structure. The inner side of the limit plate 11 is connected to the first magnetic block 12, and the inner side of the lower part of the limit plate 11 is slidably connected to the latch 13. The latch 13 is slidably connected to the track 4, and the upper side of the latch 13 is connected to the second magnetic block 131. The second magnetic block 131 can be adsorbed with the adjacent first magnetic block 12. The left and right sides of the lower part of the limit plate 11 are rotatably connected to the drive wheel 14, and the drive wheel 14 is provided with anti-slip grooves.

[0022] like Figure 1 、 Figure 3 and Figure 4As shown, a second damper 16 is also included. The inner sides of the left and right parts of the limiting plate 11 are connected to the second damper 16. The second spring 17 is connected inside the second damper 16. The inner side of the second damper 16 is connected to the second rubber pad 15.

[0023] It should be noted that the PCB board is an important component used to connect and support electronic components in electronic equipment. The PCB board forms a circuit network by laying conductive paths on an insulating substrate, thereby realizing electrical connection between electronic components. In the PCB board production process, a blanking and positioning structure is usually used to collect and transport the processed PCB boards. In the initial state, the electric push rod drives the interception plate to move upward to intercept the PCB board conveyed to the conveying component 2, and then the dual-axis motor is started. The front and rear output shafts of the dual-axis motor rotate to drive the screw to rotate, and then drive the plate collecting clamp 7 to move under the guidance of the guide rod 6. The plate collecting clamp 7 aligns the PCB board on the conveying component 2 to the center, and then the plate collecting clamp 7 is reset. At the same time, the electric push rod drives the intercepting plate to reset downward, and the conveying assembly 2 continues to convey the PCB board to the left. When the board receiving clamp 7 moves inward to contact the PCB board and align it in the center, in order to prevent the board receiving clamp 7 from having too much contact force on the PCB board and causing damage to the PCB board, the limit plate 11 can limit the adjacent board receiving clamp 7, and energize the first magnetic block 12 and the second magnetic block 131, so that the first magnetic block 12 and the second magnetic block 131 are in an adsorption state, thereby pulling the latch 13 upward, so that the adjacent limit plates 11 and the track 4 are out of the locked state, and then the limit plates 11 are slid to a suitable position by the driving wheel 14 according to the specifications of the PCB board, so that the distance between the two limit plates 11 can meet the requirements. The specifications of the PCB board are adjusted, thereby protecting the PCB board. At the same time, the second damper 16 and the second rubber pad 15 can play a buffering role when the plate clamp 7 contacts the limit plate 11, avoiding damage to the plate clamp 7. After the PCB board is centered, the plate clamp 7 is reset to the outside until it is reset to the limit position in contact with the mounting base 1. The first damper 9 and the first rubber pad 8 can protect the outside of the plate clamp 7 from shock absorption. In order to avoid the dual-axis motor driving the screw rod and the plate clamp 7 to move inward to make the PCB board centered, the dual-axis motor or other equipment failure causes the plate clamp 7 to continue to clamp the PCB board, which will cause damage to the PCB board, the first magnetic block 12 and the second magnetic block 131 can be energized so that The first magnetic block 12 and the adjacent second magnetic block 131 are attracted to each other, so that the adjacent latch 13 moves upward, so that the adjacent limit plate 11 and the track 4 are released from the locked state, and then the limit plate 11 is slid outward to a suitable position by the driving wheel 14, so that the plate receiving clamp 7 also slides outward, and the PCB board is released from the state of being continuously clamped by the plate receiving clamp 7, and then the first magnetic block 12 and the second magnetic block 131 are powered off, so that the first magnetic block 12 and the second magnetic block 131 are released from the adsorption state, and then the latch 13 locks the limit plate 11 and the track 4 again. This method can prevent the dual-axis motor or other equipment from causing damage to the clamped PCB board when a failure occurs, which is beneficial to safe production.
