Description
Technical Field
[0001] This invention relates to the field of CNC laser cutting technology, and in particular to a CNC laser cutting device for electronic product manufacturing. Background Technology
[0002] As the industry develops, electronic products are constantly moving towards miniaturization and high performance. For example, tiny components in products such as mobile phones and computers, such as chip packaging frames and precision electronic connectors, have extremely high requirements for cutting precision, which traditional cutting methods cannot meet. This has prompted CNC laser cutting equipment to innovate towards higher precision.
[0003] Currently, electronic products to be cut are usually clamped and fixed by mechanical clamping. When the electronic products are made of flexible materials, they need to be fixed carefully, and mechanical clamping can easily cause damage, affecting production efficiency and product quality. In addition, in the existing technology, metal and non-metal scraps are discarded together, and the recovery rate of precious metals (such as gold and copper) is less than 50%, which leads to waste. To address these issues, we propose a CNC laser cutting device for electronic product manufacturing. Summary of the Invention

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0026] Reference Figures 1-7 A CNC laser cutting device for electronic product manufacturing includes a worktable 1, an upper cover 26, and a lower cover 27. Two U-shaped plates 2 are symmetrically arranged on the upper part of the worktable 1. The U-shaped plates 2 are driven to move closer or further apart by a driving assembly mounted on the upper cover 26. The driving assembly includes multiple connecting plates 3 fixedly connected to the side walls at both ends of the two U-shaped plates 2. A connecting rod 4 is fixedly connected to the inner rear side wall of the upper cover 26. The connecting rod 4 slides through the two connecting plates 3 on one side. The inner rear side wall of the upper cover 26 rotates... The device is connected by a double-ended screw 5, which has threads that pass through the two connecting plates 3 on the other side. The double-ended screw 5 is driven to rotate by a servo motor 6 mounted on the rear side wall of the upper cover 26. The connecting rod 4 and the double-ended screw 5 work together to guide the U-shaped plate 2, so that the two U-shaped plates 2 can only move back and forth. The two opposite threads on the double-ended screw 5 pass through the two connecting plates 3 respectively, so that when the servo motor 6 drives the double-ended screw 5 to rotate, the two U-shaped plates 2 can move closer to each other or further away from each other under the meshing action of its threads.
[0027] Two U-shaped plates 2 are each fitted with a rotatable and adjustable fixing assembly on their opposing sidewalls. This fixing assembly secures the electronic product to be cut. The fixing assembly includes two fixing plates 7 rotatably connected to the inner sidewalls at both ends of the U-shaped plates 2. A first drive motor 8 is mounted on one sidewall of the U-shaped plate 2. The output shaft of the first drive motor 8 is connected to one of the fixing plates 7, allowing the first drive motor 8 to rotate the fixing plate 7, thereby enabling the first mounting plate 9 and the second mounting plate 10 to be flipped. The opposing sidewalls of the two fixing plates 7 are jointly fixedly connected to the first mounting plate 9 and the second mounting plate 10, which are arranged vertically. A baffle 34 is fixedly connected to the upper end of the first mounting plate 9, and at least one first cylinder 11 is mounted on the upper end of the second mounting plate 10. The first cylinder 11 penetrates the first mounting plate 9 and extends... Extending above the first mounting plate 9, a clamping plate 12 is installed at the telescopic end of the first cylinder 11. The first cylinder 11 drives the clamping plate 12 to move up and down, so that the clamping plate 12 and the first mounting plate 9 work together to clamp and fix the hard electronic product to be cut. An air pump 13 is installed at the upper end of the second mounting plate 10, and a vacuum suction cup 14 is installed at the bottom of the second mounting plate 10. The air inlet of the air pump 13 is connected to the vacuum suction cup 14. The soft electronic product to be cut is placed on the vacuum suction cup 14, and the air pump 13 pumps air from the vacuum suction cup 14 to expel the gas inside the vacuum suction cup 14, thereby fixing the soft electronic product to be cut. The arrangement of the front and rear fixing components allows the electronic product to be cut to still be fixed after it has been cut in the middle.
[0028] A laser cutting assembly is installed inside the upper cover 26. The laser cutting assembly includes a first electric slide rail 28 installed at the top inside the upper cover 26. A first electric slider adapted to the first electric slide rail 28 is installed inside the first electric slide rail 28. The first electric slide rail 28 extends horizontally, and the first electric slider slides inside the first electric slide rail 28, which can drive the laser cutting machine body 31 to move horizontally. A second electric slide rail 29 is installed at the bottom of the first electric slider. A second electric slider adapted to the second electric slide rail 29 is installed inside the second electric slide rail 29. The second electric slide rail 29 extends back and forth, and the second electric slider slides inside the second electric slide rail 29, which can drive the laser cutting machine body 31 to move back and forth. A second cylinder 30 is installed at the bottom of the second electric slider. The laser cutting machine body 31 is installed at the telescopic end of the second cylinder 30. The second cylinder 30 can drive the laser cutting machine body 31 to move up and down, thereby adjusting the position and height of the laser cutting machine body 31, which is beneficial to the laser cutting operation.
[0029] A through opening is provided on the workbench 1. The lower cover 27 is located below the workbench 1 and opposite to the through opening. A T-shaped guide plate 15 is installed inside the lower cover 27. The upper end of the T-shaped guide plate 15 is inclined so that cutting debris can move along the T-shaped guide plate 15. A magnetic adsorption assembly located at the end of the T-shaped guide plate 15 is installed inside the lower cover 27. The magnetic adsorption assembly includes an installation roller 16 rotatably installed on the rear side wall inside the lower cover 27. An annular electromagnet 17 is installed on the side wall of the installation roller 16. The installation roller 16 is driven to rotate by a second drive motor installed on the rear side wall of the lower cover 27, so that the annular electromagnet 17 is energized. The second drive motor drives the installation roller 16 to rotate, so that the annular electromagnet 17 can adsorb and collect iron debris.
[0030] A dust collection assembly located below the magnetic adsorption component is connected to the T-shaped guide plate 15 and the inner wall of the lower cover 27 via a pull-out mechanism. The dust collection assembly includes a dust collection box 18 that is pull-outly connected between the T-shaped guide plate 15 and the inner wall of the lower cover 27. Support blocks are fixedly connected to the inner walls of the dust collection box 18. A filter frame 19 is placed inside the dust collection box 18, located above the support blocks. A filter screen is installed on the filter frame 19 to filter dust particles. The support blocks support the filter frame 19, facilitating the removal of dust particles. The filter frame 19 is placed in or removed from the dust collection box 18. An air passage is provided through the side wall of the dust collection box 18 below the filter frame 19. A connecting pipe 20 opposite to the air passage is installed through the side wall of the T-shaped guide plate 15. A first exhaust fan 21 is installed at the bottom of the inner part of the lower cover 27. The air inlet pipe of the first exhaust fan 21 is detachably connected to the connecting pipe 20 through a rotary joint. The first exhaust fan 21 can perform exhaust work, which is conducive to the collection of cutting debris and dust into the dust collection box 18.
[0031] A waste gas treatment assembly is installed between the T-shaped guide plate 15 and the inner wall of the other end of the lower cover 27. The waste gas treatment assembly includes a waste gas treatment box 22 installed at the bottom of the lower cover 27. Multiple slots are provided through the waste gas treatment box 22, and honeycomb activated carbon plates 23 are inserted into each slot. The honeycomb activated carbon plates 23 can capture benzene, formaldehyde, etc., in the waste gas. A pull block 24 is fixedly connected to the upper end of the honeycomb activated carbon plate 23. The pull block 24 facilitates pulling the honeycomb activated carbon plate 23 upwards for easy replacement. The lower cover 27... A second exhaust fan 25 is installed at the bottom of the device. The air inlet of the second exhaust fan 25 is connected to the exhaust gas treatment box 22. The air outlet of the second exhaust fan 25 passes through the side wall of the lower cover 27 and extends to its outer side. The gas extracted by the first exhaust fan 21 is treated by the honeycomb activated carbon plate 23 and then discharged from the lower cover 27 by the second exhaust fan 25. This can prevent benzene, formaldehyde and other substances in the exhaust gas from being discharged. An air pressure valve is installed on the upper cover 26, which can introduce air into the device when the air pressure inside the device is low, so that the air pressure inside and outside the device can be balanced.
[0032] The front wall of the upper cover 26 is connected to a first sealing door 32 via a hinge, and the front wall of the lower cover 27 is connected to a second sealing door 33 via a hinge. Both the first sealing door 32 and the second sealing door 33 are equipped with transparent observation windows that allow for observation of the processing process. The light transmittance is ≤0.001%, meeting the laser safety level. The first sealing door 32 is equipped with a control panel that can control the opening and closing of components such as the servo motor 6, the first drive motor 8, the first cylinder 11, the air pump 13, the annular electromagnet 17, the first exhaust fan 21, the second exhaust fan 25, the first electric slide rail 28, the second electric slide rail 29, the second cylinder 30, and the laser cutting machine body 31.
[0033] The functional principle of this invention can be explained through the following operational methods:
[0034] In this invention, when the CNC laser cutting device for electronic product manufacturing is working, the first drive motor 8 can drive the fixing plate 7 to rotate, thereby flipping the first mounting plate 9 and the second mounting plate 10 so that the first mounting plate 9 faces upward or the second mounting plate 10 faces upward. When the first mounting plate 9 faces upward, the first cylinder 11 drives the clamping plate 12 to move up and down, so that the clamping plate 12 and the first mounting plate 9 work together to clamp and fix the hard electronic product to be cut. When the second mounting plate 10 faces upward, the soft electronic product to be cut is placed on the vacuum suction cup 14. The vacuum suction cup 14 is evacuated by the air pump 13, so that the gas in the vacuum suction cup 14 can be discharged, thereby fixing the soft electronic product to be cut. The arrangement of the front and rear fixing components allows the electronic product to be cut to be fixed even after it has been cut in the middle, meeting the different clamping requirements for flexible and hard materials.
[0035] The first electric slider slides within the first electric slide rail 28, which can drive the laser cutting machine body 31 to move horizontally. The second electric slider slides within the second electric slide rail 29, which can drive the laser cutting machine body 31 to move back and forth. The second cylinder 30 can drive the laser cutting machine body 31 to move up and down, thereby adjusting the position and height of the laser cutting machine body 31, which is beneficial to the laser cutting work.
[0036] The first exhaust fan 21, the second exhaust fan 25, and the second drive motor are started. The debris generated during the cutting process can fall off under the guidance of the T-shaped guide plate 15. The second drive motor drives the mounting roller 16 to rotate, which can evenly adsorb the iron debris onto the annular electromagnet 17. The first exhaust fan 21 draws negative pressure, so that the dust and debris can fall into the dust collection box 18 for collection. The filter screen can filter the dust and debris. The exhaust gas passes through the exhaust gas treatment box 22. The honeycomb activated carbon plate 23 can capture benzene, formaldehyde, etc. in the exhaust gas. The second exhaust fan 25 discharges the treated exhaust gas out of the lower cover 27.
