Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a PCB slitting device with a dust removal structure. Background Technology

[0002] With the rapid development of electronic information technology, printed circuit boards (PCBs), as core components of electronic products, have seen their application scope expand continuously, product types become increasingly diverse, and manufacturing processes become more precise and complex. In the production and processing of PCBs, slitting is a key process, mainly used to cut large-size boards into single or modular circuit boards that meet customer needs.

[0003] Currently, PCB slitting processes mainly employ methods such as mechanical blade cutting, laser cutting, and waterjet cutting. In actual operation, the cutting process inevitably generates a large amount of dust, especially when using mechanical cutting. Due to the friction between the blade and the PCB substrate, a mixture of fine and dense glass fiber dust, copper shavings, and resin particles is produced. If this dust is not removed promptly, it easily adheres to the surface of the freshly cut PCB, causing quality problems such as contamination, short circuits, and poor soldering. Dust accumulation inside the equipment can easily cause wear and tear on mechanical parts and blockages in the air passages, increasing equipment failure rates and maintenance frequency. Furthermore, PCB dust suspended in the air contains harmful substances, and long-term inhalation may damage the human respiratory system, posing a significant occupational health risk.

[0004] Therefore, it is necessary to design a PCB slitting device with a dust removal structure to solve the above-mentioned technical problems. Utility Model Content

The control panel 2 is mounted on the left side of the front side of the frame 1 by screws. The electric slide rail 3 is slidably connected inside the frame 1 and is electrically connected to the control panel 2. The first slider 4 is slidably connected to the upper part of the frame 1. The screw 15 is rotatably connected to the upper right side of the frame 1. The first motor 16 is installed on the upper front side of the frame 1 by screws. The output shaft of the first motor 16 passes through the frame 1 and is fixedly connected to the screw 15. The second slider 17 is slidably connected to the upper inside of the frame 1. The second slider 17 is threadedly connected to the screw 15. The second motor 21 is installed on the left side of the second slider 17 by screws. The output shaft of the second motor 21 extends downward and is installed with a milling cutter 22 by screws. The suction plate 5 is installed on the top of the first slider 4 by screws. The suction plate 5 has multiple round holes in a rectangular array. A connecting frame 6 is connected to and communicates with the right side of the suction plate 5. A first telescopic tube 7 is connected to and communicates with the right side of the connecting frame 6. The right end of the first telescopic tube 7 extends out of the frame 1 and is connected to and communicates with a first connecting tube 8. A dust collection box 9 is installed on the top of the frame 1 by screws. A collection frame 10 is slidably placed inside the dust collection box 9. A vent is opened on the left side inside the collection frame 10. A filter screen 11 is installed inside the vent by screws. A connecting cylinder 12 is connected to and communicates with the left side of the dust collection box 9. The connecting cylinder 12 communicates with the vent. The left end of the connecting cylinder 12 is connected to and communicates with a conveyor. Air pipe 13 is connected to and connected to air pump 14. Dust cover 18 is installed on the lower left side of the second slider 17 by screws. Milling cutter 22 is inserted into the dust cover 18. The front side of dust cover 18 is connected to and connected to second telescopic tube 19. The front end of second telescopic tube 19 extends out of frame 1 and is connected to and connected to second connecting tube 20. The upper end of second connecting tube 20 is connected to and connected to dust collection box 9. The lower end of air pipe 13 is connected to and connected to jet nozzle 23. Jet nozzle 23 is embedded in the left side of frame 1 and has an inclined structure.

[0022] When the device is needed, firstly, the electric slide rail 3 is activated via the control panel 2, driving the first slider 4 to move to the left, which in turn moves the suction plate 5 to the leftmost end of the frame 1. During this process, the first telescopic tube 7 is stretched and deformed. Then, the circuit board panel to be cut is placed on the suction cup position on the suction plate 5. Next, the air pump 14 is activated via the control panel 2 to generate negative pressure inside the suction cup, thereby firmly adsorbing and fixing the circuit board panel. Then, the first motor 16 is activated via the control panel 2, and its output shaft drives the screw 15 to rotate, causing the second slider 17 to move along the screw 15 to the left. At the designated location, during this process, the second telescopic tube 19 expands and contracts as needed to adapt to spatial changes during movement. When the second slider 17 reaches the target position, the control panel 2 shuts off the first motor 16, stopping the second slider 17 from moving. Next, the second motor 21 is started, its output shaft driving the milling cutter 22 to rotate at high speed. At this time, the electric slide rail 3 is started again, driving the first slider 4 to move horizontally to the right, thereby driving the suction plate 5 and the adsorbed circuit board panel to move to the right, so that the slot of the circuit board panel contacts the rotating milling cutter 22, completing the longitudinal cut. Afterwards, the control panel 2 starts the first motor 16 again, driving the second slider 17 to move, driving the second motor 21 and the milling cutter 22 to move laterally, so that the milling cutter 22 contacts the other slot of the circuit board panel and completes the lateral cut. This operation is repeated to cut the circuit board panel into multiple small circuit boards. During the cutting process, the air pump 14 works continuously, and the suction force generated draws the powder produced by cutting into the second telescopic tube 19 and delivers it into the collection frame 10. The filter screen 11 separates the powder from the gas. The powder is collected in the collection frame 10, and the gas... The gas is discharged from the jet pipe through the air supply pipe 13. After cutting, the gas is sprayed out to form an inclined air wall because the jet pipe is inclined. At this time, the control panel 2 controls the electric slide rail 3 to drive the first slider 4 to move to the left, which drives the suction plate 5 and the circuit board on it to move to the left. When passing through the air wall, the air wall blows away the powder remaining on the surface of the circuit board. After the circuit board is completely removed, the air pump 14 is turned off by the control panel 2, the suction force disappears, and the finished product is easy to remove. If the powder in the collection box 10 is full, it can be pulled out for cleaning. After cleaning, it can be pushed back to its original position for continued use.
