The base 1 is symmetrically slidably arranged on the left and right sides of the lower part of the sliding frame 2. The sliding frame 2 slides smoothly on the base 1. The upper part of the base 1 is fixedly provided with a rack 21. The left and right sides of the lower part of the sliding frame 2 are rotatably provided with gears 22. The gears 22 are meshed with the racks 21 on the same side. When the gears 22 rotate, the gears 22 and the racks 21 mesh with each other, which will drive the sliding frame 2 to move, and the rotation direction is changed by the gear 22 to realize the sliding frame 2 to move forward and backward on the base 1. A driving motor 3 is fixedly installed on the lower left side of the sliding frame 2. The output shaft of the driving motor 3 is fixedly connected to the gear 22 on the left side to provide a driving force for the gear 22 on the left side to rotate. A mounting frame 5 is slidably provided on the upper part of the sliding frame 2. A transmission group 4 is provided on the upper part of the sliding frame 2. The transmission group 4 consists of a screw rod and a transmission motor. The mounting frame 5 is threadedly connected to the screw rod of the transmission group 4. The transmission on the transmission group 4 When the motor rotates, it will drive the screw rod to rotate, thereby driving the mounting frame 5 to move left and right on the sliding frame 2. A cylinder 61 is fixedly installed on the mounting frame 5. The lower part of the movable rod of the cylinder is connected to a laser cutting machine 6. When the circuit board needs to be cut by the laser cutting machine 6, the movable rod of the cylinder 61 will move downward for a distance, so that the distance between the laser cutting machine 6 and the circuit board is close, and the laser cutting machine 6 slides on the mounting frame 5. An optical module 7 is fixedly installed on the right side of the lower part of the mounting frame 5. The optical module 7 will obtain, identify and analyze image information of the circuit board on the lower board rack through optical perception and image processing technology, and at the same time locate the edge of the positioning groove on the template 91, and feed back the signal in real time to control the movement of the laser cutting machine 6. Connecting rods 8 are fixedly provided on the inner side of the base 1 symmetrically front and back, and a board rack 81 is fixedly connected between the connecting rods 8. A template 9 is slidably provided on the upper part of the board rack 81.

[0023] When it is necessary to cut the circuit board, first slide the template 9 backward and move it away, place the circuit board to be cut on the board rack 81, and then slide the template 9 forward to reset it. The bottom side of the template 9 on the board rack 81 will contact the top side of the circuit board, and the template 9 will completely cover the circuit board. The positioning groove 91 on the template 9 will move with the template 9 to the cutting area on the motherboard that needs to be cut into small pieces of circuit boards. When the knife is lowered, the laser beam emitted by the cutting laser cutting machine 6 will move along the edge of the positioning groove 91 on the template 9 for one circle according to the set program to cut the circuit boards one by one. When the template 9 is positioned, start the drive motor 3 and the transmission motor on the transmission group 4. Before cutting, the optical module 7 will output a signal to the drive motor 3 and the transmission motor by locating the position of a single positioning groove 91. The machine 3 will drive the sliding frame 2 to move forward and backward, and the transmission motor will drive the mounting frame 5 to move left and right. The two cooperate with each other to realize the positioning and mobile cutting of the laser beam of the laser cutting machine 6 when cutting the circuit board. When the laser cutting machine 6 needs to cut, the movable rod of the cylinder 61 extends downward for a section, so that the laser cutting machine 6 is close to the template 9, and the circuit boards are cut one by one. The circuit boards cut in the positioning grooves 91 will fall down. After the laser cutting machine 6 cuts all the areas in the positioning grooves 91, the small pieces of circuit boards on the circuit board motherboard that need to be cut are all cut off, and then the sliding frame 2 is controlled to move backward, and the cylinder 61 drives the laser cutter to move upward and reset, and finally the template 9 is slid backward, the remaining materials after the circuit board is cut on the board rack 81 are taken away, and all the small pieces of circuit boards that have been cut are collected and taken away to complete the cutting work.

The blanking plates 101 are fixedly welded between the sliding plates 10. The blanking plates 101 are used for collecting the circuit boards after the laser cutting machine cuts them, without picking up the single pieces one by one at the bottom of the device. The sliding plate 10 slides smoothly in the slide groove without obstruction.

The suction head 12 is installed on the upper right side of the template 9, and the air duct 11 is fixedly installed on the right side of the template 9. The air duct 11 and the suction head 12 are connected and communicated through a pipeline. A joint is reserved at the rear of the air duct 11 for convenient access to external smoke exhaust equipment. The smoke generated during laser cutting will be sucked away through the suction head 12 and transmitted to the smoke exhaust equipment through the connected air duct 11.

A second cylinder 14 is fixedly installed on the left side of the template 9 to provide thrust or pulling force instead of manual operation. The movable rod of the second cylinder 14 is fixedly connected to the plate rack 81. A pull rope 15 for transmitting pulling force is wound around the outside of the wire wheel 13. One end of the pull rope 15 is connected to the front part of the same side of the template 9, and the other end of the pull rope 15 is connected to the sliding plate 10 on the rear side. A spring 16 is provided in the slide groove of the right side of the base 1, and both ends of the spring 16 are respectively connected to the rear wall of the slide groove and the right rear side of the sliding plate 10 on the rear side.

At this time, the blanking plate 101, the plate rack 81 and the template 9 are arranged in a stepped manner. After the circuit board motherboard to be cut is placed on the plate rack 81, the cylinder 2 14 is controlled to retract the active rod. When the active rod is retracted, since the front part of the active rod is fixedly connected to the fixed plate rack 81, when moving, the cylinder 2 14 body drives the template 9 to move forward and reset. Under the action of the spring 16, the sliding plate 10 on the rear side moves and resets, and the sliding plate 10 drives the blanking plate 101 to move backward and reset. After the reset, the blanking plate 101 will be in a position directly below the plate rack 81. Before cutting, the external pump is connected to the joint reserved on the air duct 11. The smoke removal device for removing smoke. When the laser cutting machine 6 is cutting, the small circuit boards cut out will fall on the blanking plate 101. During cutting, the smoke generated by laser cutting will be sucked away by the external smoke removal device on the air duct 11 through the suction head 12, so as to prevent the smoke generated by cutting from spreading in the air and being inhaled into the body by people, causing harm to the human body. After the cutting is completed, the control cylinder 2 14 extends the movable rod, and the template 9 slides backward. Under the action of the pull rope 15 on the template 9, the sliding plate 10 is dragged forward. When the template 9 slides backward, the blanking plate 101 moves forward, which is convenient for people to quickly collect the circuit boards dropped on the blanking plate 101. At the same time, the template 9 on the plate rack 81 is quickly opened and the blanking plate 101 is moved out through the cylinder 2 14 and the pull rope 15. There is no need to move manually, and the action is coherent and fast, which is convenient for people to collect and change the plates after cutting.
