Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, and specifically relates to a burr cutting device after pressing in circuit board production. Background Art

[0002] In the manufacturing process of multi-layer pcb circuit boards, it generally includes multiple processes such as blanking, inner layer pattern manufacturing, lamination, drilling, copper deposition, etc. In the process, lamination means stacking the manufactured inner layer boards, prepregs, and outer copper foils in sequence and then hot pressing them into one body. After hot pressing, a multi-layer board is formed. At this time, there are generally many burrs on the outer side of the multi-layer board. Such burrs need to pass through a cutting device to enter the next process.

[0003] The Chinese utility model patent with the publication number of CN218905579U discloses a circuit board cutting device. This device can conveniently limit and cut circuit boards of different specifications, and inhale and purify the waste dust generated during cutting, solving the problems of no purification function, the dust generated during cutting cannot be purified in time, and the circuit boards of various specifications cannot be cut, reducing the use effect.

[0004] The above device and the prior art both deal with the dust or circuit boards generated during cutting. The burrs cut from the circuit board are generally directly collected in the transfer frame. Such cut burrs often have great recycling value, and directly placing them in the transfer frame will greatly reduce the storage effect of the transfer frame. Summary of the Invention
