Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a corner cutting machine for circuit board processing. Background Technology

[0002] Circuit boards are the core basic components that provide mechanical assembly support and electrical connection for various electronic systems, and also carry out signal transmission, signal reception and power supply for electronic devices. In order to facilitate the installation and layout of circuit boards and improve safety and aesthetics, corner cutting machines are usually used to cut the corners of circuit boards during the processing.

[0003] In the prior art, patent publication number CN 211047423 U discloses a corner-cutting device for integrated circuit board production and assembly, including a frame and a base plate. The base plate is installed on one side of the bottom of the inner cavity of the frame, an electric telescopic rod is installed on one side of the top surface of the frame, a top plate is installed on the top surface of the electric telescopic rod, a motor is installed on one side of the bottom of the top plate, a cutting blade is installed on one side of the motor, and a first dust suction pipe is installed on one side of the cutting blade. This utility model uses an electric telescopic rod to drive the motor to lift and lower via the top plate, thereby enabling the high-speed rotating cutting blade to cut the integrated circuit board, which can improve the cutting efficiency, cutting accuracy and quality of the integrated circuit board. Through the cooperation of a vacuum cleaner and a second dust suction pipe, the debris and dust generated by the cutting blade in cutting the integrated circuit board can be absorbed and collected, thereby reducing environmental pollution. Some corner-cutting machines do not have independent dust suction components. After the corner is cut, the worker uses an external vacuum cleaner to clean the surface of the processing table.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a corner-cutting machine for circuit board processing, including a processing table 1, a cutting blade 12 mounted on the upper surface of the processing table 1 via an adjustable movable frame 5, a collecting mechanism 3, and a microcontroller 2. The microcontroller 2 is located on the front side of the processing table 1, and its input is electrically connected to an external power source. An electric push rod 6 and a limiting rod 4 are mounted on the upper surface of the processing table 1. The movable frame 5 is mounted on the upper end of the telescopic shaft of the electric push rod 6. The left side of the movable frame 5 is slidably connected to the outer surface of the limiting rod 4. The input of the electric push rod 6 is electrically connected to the output of the microcontroller 2. The cutting blade 12 is rotatably connected to the right side of the movable frame 5 via a rotating shaft. A motor 7 is mounted on the lower surface of the movable frame 5, and the output shaft of the motor 7 is located on the right side. The left end of the machine table 1 is fixedly connected to the rotating shaft. The input end of motor 17 is electrically connected to the output end of microcontroller 2. A lead screw 9 is rotatably connected inside the slot on the upper surface of the machine table 1. A fixed seat 10 is threadedly connected to the outer surface of lead screw 9. The lower end of the fixed seat 10 is slidably connected to the inside of the slot. A motor 11 is provided on the right side of the machine table 1. The left end of the output shaft of motor 11 is fixedly connected to the right end of lead screw 9. The input end of motor 11 is electrically connected to the output end of microcontroller 2. The machine table 1 also includes a fixing mechanism 8. The fixing mechanism 8 includes a slide 81, a lead screw 82, a clamping plate 83, and a turntable 84. (The exposed parts of the outer surfaces of lead screw 82 and lead screw 9 are fitted with corrugated tubes. The ends of the corrugated tubes are respectively connected to the side of clamping plate 83 and the side of slide 8.) The side of the fixed seat 10 and the side of the slot are fixedly connected. The bellows is reserved with sufficient length. When the clamping plate 83 or the fixed seat 10 moves, the bellows on one side contracts and the bellows on the other side extends, so that when the lead screw 82 or the lead screw 9 is working, the bellows always wraps around and shields the lead screw 82 and the lead screw 9 to prevent dust from affecting the threaded transmission between the lead screw 82 and the clamping plate 83 and between the lead screw 9 and the fixed seat 10. The upper surface of the fixed seat 10 has sliding grooves 81 on both the front and rear sides. The lead screw 82 is rotatably connected inside the sliding grooves 81. The outer surface of the lead screw 82 is threadedly connected to the clamping plate 83. The lower end of the clamping plate 83 is slidably connected to the inside of the adjacent sliding groove 81. The right end of the lead screw 82 is provided with a turntable 84. The worker places the circuit board on the fixed seat 10, and then rotates the lead screw 82 through the turntable 84. The rotation of the lead screw 82 drives the threaded clamp 83 to slide along the slide groove 81 until the clamps 83 on both sides, together with the fixed seat 10, fix the circuit board. Then, the microcontroller 2 is operated to turn on the motor 11. The output shaft of the motor 11 drives the lead screw 9 to rotate. The rotation of the lead screw 9 drives the circuit board to move through the fixed seat 10. When the circuit board moves to the processing position, the motor 7 and the electric push rod 6 are turned on. The output shaft of the motor 7 drives the cutting blade 12 to rotate. The telescopic shaft of the electric push rod 6 drives the movable frame 5 to rotate and the limit rod 4 to move downward, causing the rotating cutting blade 12 to move downward to cut the corner of the circuit board.

[0023] Collection mechanism 3 includes a dust collection box 31, a debris collection box 32, a fan 33, a dust collection pipe 34, a dust collection hood 35, and a filter screen 36. The bottom wall of the processing table 1 is equipped with a dust collection box 31 and a fan 33. The discharge port on the front side of the dust collection box 31 is connected to the air intake port of the fan 33 through a pipe. The debris collection box 32 is slidably connected to the opening on the left side of the dust collection box 31. (A sealing strip is provided on the right side of the debris collection box 32 to ensure a tight seal when closed. The debris collection box 32 is connected to the dust collection box 36.) A door lock is provided at the junction of the box 31 (the door lock uses a common connection method in the prior art). A filter screen 36 is provided in the mounting groove on the lower surface of the debris collection box 32. A dust collection pipe 34 is provided at the feed inlet on the left side of the dust collection box 31. The middle part of the dust collection pipe 34 is a corrugated steel wire pipe. The upper end of the dust collection pipe 34 passes through the left side of the movable frame 5 and is provided with a dust collection hood 35. The input end of the fan 33 is electrically connected to the output end of the microcontroller 2. The collection mechanism 3 also includes a debris collection component 37. The dust collection assembly 37 includes a guide channel 371, a clearance channel 372, and a collection box 373. The guide channel 371 is provided on the upper surface of the processing table 1, and the guide channel 371 is inclined at the front and higher at the back. The clearance channel 372 is provided on the front side of the processing table 1, and the collection box 373 is slidably connected inside the clearance channel 372. At the same time, the fan 33 is turned on, and under the action of the fan 33, the airflow carries the debris together through the dust suction hood 35 and the dust suction pipe 34 and is sucked into the dust collection box 31. Airflow passes through filter screen 36 and exits dust collection box 31, while debris is blocked by filter screen 36 and remains in dust collection box 31. After the corner cutting machine has been working for a period of time, the operator can open the door lock and pull out the debris drawer 32 from dust collection box 31 to clean the debris and filter screen 36 collected inside the debris drawer 32. Larger objects cut off are moved into collection box 373 through guide channel 371. The operator can pull out collection box 373 along clearance channel 372 using the handle.

[0024] The working principle of the corner-cutting machine for circuit board processing provided by this utility model is as follows: The operator places the circuit board on the fixed seat 10, and then rotates the lead screw 82 through the turntable 84. The rotation of the lead screw 82 drives the threaded clamping plate 83 to slide along the slide groove 81 until the clamping plates 83 on both sides, together with the fixed seat 10, fix the circuit board. Then, the microcontroller 2 is operated to turn on the motor 11. The output shaft of the motor 11 drives the lead screw 9 to rotate. The rotation of the lead screw 9 drives the circuit board to move through the fixed seat 10. When the circuit board moves to the processing position, the motor 7 and the electric push rod 6 are turned on. The output shaft of the motor 7 drives the cutting blade 12 to rotate. The telescopic shaft of the electric push rod 6 drives the movable frame 5 to rotate the limit rod 4. The downward movement causes the rotating cutting blade 12 to move downward to cut the corner of the circuit board. At the same time, the fan 33 is turned on. Under the action of the fan 33, the airflow carries the debris through the dust hood 35 and the dust suction pipe 34 into the dust collection box 31. The airflow passes through the filter screen 36 and is discharged from the dust collection box 31, while the debris is blocked by the filter screen 36 and remains in the dust collection box 31. After the corner cutting machine has been working for a period of time, the operator can open the door lock and pull the debris drawer 32 out of the dust collection box 31 to clean the debris and filter screen 36 collected inside the debris drawer 32. Larger objects cut off are moved into the collection box 373 through the guide channel 371. The operator can pull the collection box 373 out along the clearance channel 372 using the handle.

[0025] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an EFR32MG21, the fan 33 can be a CX-75 medium-pressure fan, and the motor 7 and motor 11 can be YP-100 series. The microcontroller 2 controls the operation of the fan 33, the electric push rod 6, the motor 7 and motor 11 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
