It is widely used in electronics manufacturing, repair, and research and development to ensure that circuit boards can be efficiently and accurately divided according to design requirements.
[0003] Some existing circuit board cutting machines require operators to hold the circuit board while cutting. This not only increases the labor intensity of the operators, but also poses significant safety hazards because the high-speed rotating blade is too close to the operator's hand. Utility Model Content
[0004] In order to overcome the shortcomings of some existing circuit board cutting machines that require operators to hold the circuit board while cutting, which poses a significant safety hazard, the purpose of this utility model is to provide a protective circuit board cutting machine.
[0005] The present invention provides a protective circuit board cutting machine, comprising a housing, a connecting plate, a bidirectional threaded rod, a fixing block, a rotary motor, a moving frame, bolts, clamps, a cutting blade, a reciprocating mechanism, and a high-speed motor. The connecting plate is connected to the lower inner side of the housing. A through groove is formed on the front side of the connecting plate. A rotary motor is located at the front bottom of the connecting plate. Fixing blocks are symmetrically arranged on the left and right sides of the bottom of the connecting plate. A bidirectional threaded rod is rotatably connected between the two fixing blocks. One end of the bidirectional threaded rod is connected to the output shaft of the rotary motor. Moving frames are threadedly connected to the left and right sides of the bidirectional threaded rod. Both moving frames slide within the through groove. Each moving frame has a threaded hole at its top, and bolts are threaded into these holes. Clamps are connected to the bottom ends of the bolts. A reciprocating mechanism is located at the front top of the inner end of the housing. A connecting block is connected to the reciprocating mechanism. A cutting blade is rotatably connected to the front end of the connecting block. A high-speed motor is located at the rear end of the connecting block, and the output shaft of the high-speed motor is connected to the cutting blade.
[0006] Furthermore, the reciprocating mechanism includes a base, a drive motor, a reciprocating screw, a guide rod, and a slider. The base is connected to the front side of the top of the housing. The drive motor is located at the right end of the base. The reciprocating screw is rotatably connected to the base and is connected to the output shaft of the drive motor. Guide rods are symmetrically arranged at the front and back of the lower part of the base. A slider is slidably connected to the guide rod. The upper part of the slider is located in the threaded groove of the reciprocating screw, and the bottom end of the slider is connected to the top of the connecting block.
[0007] Furthermore, it also includes rubber sheets, with rubber sheets provided at the bottom of each clamp.
[0008] Furthermore, it also includes protective blocks, with protective blocks symmetrically arranged on the left and right sides of the front end of the connecting block.

[0010] Furthermore, it also includes a lighting fixture, which is connected to the rear side of the top of the housing.
[0011] The beneficial effects are as follows: 1. The design of the movable frame eliminates the need for workers to manually cut circuit boards, which not only reduces manual intervention but also significantly lowers operational risks. The rotation of the bidirectional threaded rod, driven by a rotary motor, allows the two movable frames to move closer or further apart, enabling the equipment to automatically adjust their positions according to the width of the circuit board, ensuring that circuit boards of different specifications can be securely fixed.
[0012] 2. The lighting provides ample light, allowing operators to observe the cutting process in dim environments and ensuring operational accuracy. Attached Figure Description

The connecting plate 101 is connected to the lower inner side of the housing 1, and can support the cut circuit board. A through slot is opened on the front side of the connecting plate 101. A rotary motor 3 is located at the front bottom of the connecting plate 101. Fixing blocks 201 are symmetrically arranged on the left and right sides of the bottom of the connecting plate 101. A bidirectional threaded rod 2 is rotatably connected between the two fixing blocks 201. One end of the bidirectional threaded rod 2 is connected to the output shaft of the rotary motor 3. Moving frames 4 are threadedly connected to both the left and right sides of the bidirectional threaded rod 2. Both moving frames 4 slide within the through slots. The bolts on the left and right sides of the bidirectional threaded rod 2... The rotation directions are opposite. When the rotary motor 3 drives the bidirectional threaded rod 2 to rotate, the moving frames 4 on the left and right sides will move along the through groove to move closer to each other or further away from each other. The top of each moving frame 4 has a screw hole, and each screw hole is threaded with a bolt 5. The bottom of each bolt 5 is connected to a clamping plate 6. Rotating the bolt 5 can make the clamping plate 6 rise or fall. The front side of the inner top of the outer shell 1 is provided with a reciprocating mechanism 9. A connecting block 7 is connected to the reciprocating mechanism 9. The front end of the connecting block 7 is rotatably connected to a cutting blade 8. The rear end of the connecting block 7 is provided with a high-speed motor 10. The output shaft of the high-speed motor 10 is connected to the cutting blade 8. The high-speed motor 10 drives the cutting blade 8 to rotate at high speed. The reciprocating mechanism 9 can drive the connecting block 7 and the cutting blade 8 on it to move. The high-speed rotating cutting blade 8 cuts the circuit board.
[0020] like Figure 3 and Figure 4 As shown, the reciprocating mechanism 9 includes a base 901, a drive motor 902, a reciprocating screw 903, a guide rod 904, and a slider 905. The base 901 is connected to the front side of the top end inside the housing 1. The drive motor 902 is located at the right end of the base 901. The reciprocating screw 903 is rotatably connected to the base 901. The reciprocating screw 903 is connected to the output shaft of the drive motor 902, and the drive motor 902 drives the reciprocating screw 903 to rotate. The guide rods 904 are symmetrically arranged at the front and rear of the lower part of the base 901, and the slider 905 is slidably connected to the guide rods 904. 05. The upper part of the slider 905 is located in the threaded groove of the reciprocating screw 903. The rotation of the reciprocating screw 903 drives the slider 905 to move. The guide rod 904 guides the slider 905. The slider 905 moves along the threaded groove on the reciprocating screw 903 to the left side of the reciprocating screw 903, and then moves along the threaded groove on the reciprocating screw 903 to the left and right sides of the reciprocating screw 903. The slider 905 moves back and forth. The bottom end of the slider 905 is connected to the top end of the connecting block 7. The slider 905 can move left and right with the connecting block 7.
[0021] like Figures 1-4As shown, it also includes a support plate 102, a rubber plate 601, a protective block 701, and a lighting lamp 11. The support plate 102 is connected to the front right side of the outer casing 1. The left side of the support plate 102 is in contact with the connecting plate 101. The left side of the support plate 102 is located between the cutting blade 8 and the movable frame 4. The cutting blade 8 is close to the right end of the support plate 102. When the circuit board is fixed to the movable frame 4, the bottom end of the circuit board is connected to the top end of the support plate 102. The support plate 102 supports the circuit board. The bottom end of the clamping plates 6 is provided with a rubber plate 601. When the clamping plates 6 are used for When fixing the circuit board, the rubber plate 601 directly contacts the circuit board. The rubber plate 601 can prevent the surface of the circuit board from being scratched. Protective blocks 701 are symmetrically arranged on the left and right sides of the front end of the connecting block 7. The protective blocks 701 are located on the left and right sides of the cutting blade 8. The presence of the protective blocks 701 can further improve the safety of this equipment and prevent accidents from happening during the cutting process of the cutting blade 8. A lighting lamp 11 is connected to the rear side of the top of the inner shell 1. When the light is dim, the lighting lamp 11 can be turned on. The lighting lamp 11 can provide sufficient light to facilitate the operator to observe the cutting process.
[0022] Adjust the distance between the two moving frames 4 according to the width of the circuit board to be cut. Start the rotary motor 3, which drives the bidirectional threaded rod 2 to rotate, causing the two moving frames 4 to move closer or further apart. When the circuit board to be cut can be placed between the two moving frames 4, turn off the rotary motor 3, place the circuit board to be cut on the two moving frames 4, and rotate the bolt 5 to bring the clamping plate 6 close to the circuit board and clamp it, ensuring that the circuit board is firmly fixed on the moving frames 4. At this time, the bottom end of the circuit board is in contact with the support plate 102. After the circuit board is fixed, start the drive motor 902, which drives the reciprocating screw 903 to rotate. The slider 905 moves to the left along the guide rod 904, thereby moving the connecting block 7. At the same time, the high-speed motor 10 is started, and the high-speed motor 10 drives the cutting blade 8 to rotate at high speed. The connecting block 7, with the cutting blade 8, cuts the circuit board, and the circuit board is divided into two parts. One part remains on the moving frame 4, and the other part falls on the connecting plate 101. After the cutting task is completed, the high-speed motor 10 and the drive motor 902 are turned off in sequence, and the bolt 5 is rotated in the opposite direction so that the clamping plate 6 no longer clamps the circuit board. The circuit board on the moving frame 4 is removed and replaced with another circuit board to be cut. The above operation process is repeated to cut the circuit board.
