Prepreg, also known as "PP sheet" or "PP", is one of the main materials used in the production of multilayer boards, mainly consisting of resin and reinforcing material. Play the role of insulation between the board layers. The prepreg is applied to the circuit board after cutting and other processes.
What is the troubling problem in the traditional process of cutting prepreg ( PP )?
The main appearance requirements of the prepreg used for the multilayer board are the cloth surface should be flat, no oil, no stains, no foreign impurities or other defects, no rupture and excessive resin powder, but micro-cracks are allowed. However, with the use of a traditional prepreg cutting machine, the edges will be whitening, folding, wrinkling, charring, and other phenomena, while generating a large amount of dust and glass drawing, which can easily lead to defects such as dents in the subsequent press-fit process of the semi-curing sheet, which will also affect the quality of the circuit board products.
2. Environmental pollution.
The fine dust generated by cutting is easy to float in the air, causing environmental pollution, human inhalation deposited in the lungs, long-term operations inhalation of large amounts of dust, seriously endangering the health of staff. In addition, the dust particles are too small, easy to irritate the skin, causing skin allergies and other symptoms.
3. Consumption of manpower.
This will also lead to the workshop, equipment in a short period of time to accumulate too much dust, the need to spend a lot of manpower and material resources every day to clean up the dust, increasing labor costs and production burden.
Cutting process and effect of the traditional single mechanical cutting machine.
Is there any good way to solve it?

2. Equipped with high-efficiency dust-absorbing device: suction while cutting, no place for dust to escape
In addition to the substantial reduction of dust in the production source of cutting, prepreg dust-free automatic cutting machine also added a highly efficient dust suction device, can be achieved while cutting, dual-pronged, so that the small amount of dust generated nowhere to escape, the overall reduction rate of the equipment cut dust amount of more than 98%.
Compared with peer products and other traditional products, Zhengye Technology's Prepreg dust-free automatic cutting machine has leading advantages in cutting effect and dust reduction and also has outstanding performance in cutting accuracy and efficiency, using the advanced servo control system, cutting accuracy up to ±1 mm, cross-cutting and longitudinal cutting dynamic heating, no follow-up processing, cutting efficiency up to 21 knives/min, realize one key automatic knife adjustment, PP The overall technology has reached the leading level at home and abroad.
In addition to the advantages of precision, high quality, high efficiency, low dust, health, and environmental protection, the cutting machine can be adapted to the prepreg automatic collecting machine to replace manual stacking and finishing.
1、After the operator gets on PP, he can scan the code work order to get the production information: cutting material number, length, width, quantity, and other information.
2、After the machine obtains the information, it will automatically complete the slitting knife adjustment and then cut.
► Low dust and environmental protection.
Adopting infrared heating technology, the amount of dust in the incision is reduced by more than 98%, and the dust-absorbing device is added, which is environmentally friendly and healthy.
► High precision.
Adopting servo control system, the cutting accuracy is up to ±1 mm.
► High efficiency.
Cross-cutting and slitting dynamic heating, no need for follow-up processing, cutting efficiency can reach 21 knives/min, realize one-key automatic knife adjustment, PP sheets can be stacked automatically.
► High quality.
The cutting edge is neat, no burr, no powder loss, no scorching, and automatic edge sealing.
Compared with peer products and other traditional products, this equipment has leading advantages in cutting efficiency, cutting effect,and dust generation rate and the overall technology has reached the international leading level. At the same time, the equipment meets the requirements of production line planning, high efficiency, multi-model compatibility and short changeover time, etc. Compared with other similar products, it can control the overall cost reduction by more than 30%.
Zhengye prepreg collecting machine operation process.
1、Receiver is directly docked with the cutter discharge port to automatically complete stacking and receiving.
2、The whole collected PP is transported to the perforating machine station.
► Improve product yield.
Fully automatic receiving and stacking, stacking neatly, avoiding punching misalignment, reducing manual contact with PP, avoiding foreign objects from being brought in, and bending the semi-cured sheet.
► Cost-saving.
No need for manual assistance to receive the material, one person, multiple machines, save manpower and increase production value.
►Automation.
Automatic stacking neatly, no need to assist in receiving, can be docked with the next process automation, connected to the factory production management system.
►Product stability and quality advantages.
Adopt Siemens control system and dust sealing type module, the structure has been simulated and designed to ensure the quality.
Zhengye prepreg drilling machine operation process.
1、PP conveyed from the previous process is automatically loaded and positioned at the punching station.
2、The machine automatically reads the electronic tag information on top of the PP carrier, gets the punching information, automatically completes punching and writes information to the electronic tag so that the next station can use the information and discriminate.
3、After the completion of punching, the machine will automatically dismount the material and convey it to the designated position by AGV or conveyor belt.
Note: There are pads on the PP carrier (below the PP) and on the top of the PP, and the pads are replaced regularly as wearing parts.
