Description

Technical Field

[0001] This invention relates to the field of sheet metal drilling technology, specifically to a PAD hole drilling machine for automotive sheet metal production equipped with a corrosion module. Background Technology

[0002] With the rapid development of automotive electronics, industrial automation, and other fields, the demand for high-performance and high-reliability PCBs will continue to grow. Ultra-thick copper automotive PCBs, due to their superior performance characteristics, will find wider application in these fields. In the future, with continuous innovation and advancements in PCB manufacturing technology, the manufacturing process for ultra-thick copper automotive PCBs will also be continuously optimized and improved to meet increasingly diverse market demands.

[0003] Ultra-thick copper automotive PCBs are a special type of printed circuit board widely used in the automotive electronics field. Their key feature is the use of ultra-thick copper foil as the conductive material. Processing ultra-thick copper automotive PCBs requires drilling holes in the substrate. Traditional hole pads are designed as circular shapes, with the hole diameter smaller than the pad. Depending on the total copper thickness, several sheets can be stacked for drilling, resulting in relatively good drilling quality. However, current drilling methods involve drilling the entire copper surface. During drilling, the high-speed drill bit penetrates each copper layer, generating immense heat for each thick copper layer. This leads to significant wear on the drill bit's cutting edge, poor chip removal, and the production of low-quality products.

[0004] Therefore, in order to address the above problems, the applicant needs to design a PAD hole drilling machine for automotive sheet production with a corrosion module to solve the problem. Summary of the Invention

[0026] Compared with the prior art, the beneficial effects of the present invention are: the PAD hole drilling machine for automotive sheet production equipped with an etching module can etch away the inner layer base copper in the middle of the drilling area by using the etching mechanism, thereby reducing the copper thickness in the middle part, which will greatly reduce the heat generated by the drill bit during operation, thereby reducing the wear of the drill bit cutting edge, improving the chip removal capacity, and producing high-quality products. The specific details are as follows.

[0027] 1. Equipped with an etching mechanism, during use, the buffer box containing the multilayer board substrate is transported to the area below the nozzle using a conveying assembly. Then, the water pump is activated according to the thickness and material of the board substrate. The water pump draws clean water from the buffer box into the connecting pipe. Under pressure, the clean water in the connecting pipe easily enters the buffer cylinder containing a high-concentration etching solution. After the clean water and etching solution are mixed, the nozzle is opened, and the nozzle draws the etching solution of the target concentration and drips it onto the center of the drilling area of ​​the board substrate. This can etch away the inner copper base layer in the center of the drilling area, reducing the copper thickness in the center. This greatly reduces the heat generated by the drill bit during operation, thereby reducing the wear of the drill bit's cutting edge, improving chip removal capability, and producing high-quality products.

[0028] 2. Equipped with a corrosion protection mechanism, when in use, the atomizing nozzle is turned on, and the pump inside the atomizing nozzle draws clean water from the buffer tank into the delivery hose. Under pressure, the clean water in the delivery hose enters the buffer chamber, where it is easily atomized and sprayed out through the atomizing nozzle. This helps to reduce the ambient temperature around the drill bit during drilling and improve product quality.

[0029] 3. Equipped with a drilling mechanism, when in use, the first linear module and the second linear module are started, and the drilling position of the drill bit is freely adjusted. After the drill bit is adjusted, the motor is started. The motor drives the pulley assembly to work, and the pulley assembly drives the drill bit to rotate, thereby improving the drilling efficiency and drilling quality. Attached Figure Description

A buffer box 31 is fixedly mounted on the top surface of the fixed base 30, and a water inlet pipe 310 fixedly connected to an external water source is mounted on the top surface of the buffer box 31. A connecting pipe 32 is fixedly connected to one side of the buffer box 31, and a buffer cylinder 33 fixedly connected to the fixed base 30 is fixedly connected to the end of the connecting pipe 32 away from the buffer box 31. A connecting hose 34 is fixedly connected to the top surface of the buffer cylinder 33. The end of the connecting hose 34 away from the buffer cylinder 33 is fixedly connected to an extension pipe 35. The end of the extension pipe 35 away from the connecting hose 34 is fixedly connected to a nozzle 36, and the nozzle 36 is located above the conveying assembly 11.

[0043] Based on the above structural design, Figure 1 , Figure 2 and Figure 7 As shown, during use, the buffer box 12 containing the multilayer board substrate is transported to below the nozzle 36 using the conveying assembly 11. Then, the water pump 320 is started according to the thickness and material of the board substrate. The water pump 320 draws clean water from the buffer box 31 into the connecting pipe 32. Under pressure, the clean water in the connecting pipe 32 easily enters the buffer cylinder 33 containing high-concentration etching solution. After the clean water and etching solution are mixed, the nozzle 36 is opened. The nozzle 36 draws the etching solution of the target concentration and drips it onto the middle position of the drilling area of ​​the board substrate. This can etch away the inner base copper in the middle of the drilling area, reducing the copper thickness in the middle part. This greatly reduces the heat generated by the drill bit 224 during operation, thereby reducing the wear of the drill bit 224 cutting surface, improving chip removal capability, and producing high-quality products.

[0045] Based on the above structural design, Figure 1 , Figure 2 and Figure 7 As shown, when in use, the atomizing nozzle 381 is turned on, and the pump inside the atomizing nozzle 381 draws clean water from the buffer tank 31 into the delivery hose 38. Under pressure, the clean water in the delivery hose 38 enters the buffer chamber 380. The clean water in the buffer chamber 380 is easily atomized and sprayed out through the atomizing nozzle 381, which helps to reduce the ambient temperature around the drill bit 224 during drilling and improve product quality.

[0046] Working Principle: When using this PAD hole drilling machine for automotive sheet production equipped with an etching module, the conveying assembly 11 transports the buffer box 12 containing multilayer board substrate to below the nozzle 36. Then, the water pump 320 is activated according to the thickness and material of the board substrate. The water pump 320 draws clean water from the buffer box 31 into the connecting pipe 32. Under pressure, the clean water in the connecting pipe 32 easily enters the buffer cylinder 33 containing high-concentration etching solution. After the clean water and etching solution are mixed, the nozzle 36 is opened, and the nozzle 36 draws the etching solution of the target concentration and drips it onto the center of the drilling area of ​​the board substrate. This can etch away the inner base copper layer in the center of the drilling area, reducing the copper thickness in the center. This greatly reduces the heat generated by the drill bit 224 during operation, thereby reducing the wear of the drill bit 224 cutting edge, improving chip removal capacity, and increasing production efficiency. High-quality product. Simultaneously, the atomizing nozzle 381 is opened. The pump inside the atomizing nozzle 381 draws clean water from the buffer tank 31 into the delivery hose 38. Under pressure, the clean water in the delivery hose 38 enters the buffer chamber 380. The clean water in the buffer chamber 380 is easily atomized and sprayed out through the atomizing nozzle 381, which helps to reduce the ambient temperature around the drill bit 224 during drilling. After the substrate is corroded, the buffer box 12 is transported to the bottom of the drill bit 224 using the delivery assembly 11, and the first linear module 200 and the second linear module 205 are activated to freely adjust the drilling position of the drill bit 224. After the drill bit 224 is adjusted, the motor 222 is started. The motor 222 drives the pulley assembly 223 to work, and the pulley assembly 223 drives the drill bit 224 to rotate, thereby improving the drilling efficiency and drilling quality.
