Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting and cutting blade technology, and more specifically, to a double-headed slitting and cutting blade with a ventilation switching mechanism. Background Technology
[0002] Circuit boards are essential components in electronic products. During the manufacturing process, circuit board splitting machines are used to separate circuit boards. A circuit board splitting machine is a machine that cuts off the ribs of multiple circuit boards (PCBs) that are originally mounted as a single unit, thus separating them into individual circuit boards.
[0003] When a depaneling machine is depaneling, it uses a blade to cut or drill holes in the circuit board product from the whole PCB board. During this process, a lot of dust will be generated, and the dust will fall onto the PCB board. In order to prevent the dust from remaining on the PCB board and causing damage, the operator also needs to clean the PCB board after it has been depaneled by the depaneling machine.
[0004] Currently, the structure of a typical PCB depaneling machine with a dust-collecting function is shown in the patent document with patent number CN201610058829.6 and title "PCB Depaneling Machine Dust-Collecting Milling Cutter". It includes: a horizontal moving device, a lifting device set on the horizontal moving device, and a milling cutter device set on the lifting device. The lifting device and the horizontal moving device, and the milling cutter device and the lifting device slide together. The milling cutter device includes a milling cutter seat (1) and a milling cutter (2) set on the top of the milling cutter seat (1). A dust-collecting chamber (3) is also provided on the milling cutter seat (1). The dust-collecting chamber (3) covers the periphery of the milling cutter (1), and several anti-static brushes (4) are provided on the dust-collecting chamber (3). The anti-static brushes (4) are at the same height as the milling cutter (2). The dust-collecting chamber (3) is also connected to a dust-collecting pipe (5).
[0005] This depaneling machine is a single-head milling cutter type, using a rotary milling cutter to mill away the remaining portion along the VCUT path to achieve complete separation. It minimizes stress and produces the smoothest edges, making it suitable for precision or fragile component boards.
[0006] Besides milling cutter type, commonly used panel separation processes also include push-cut type, which fixes the panel and uses a linearly moving cutter to push along the VCUT line to separate the panel. This method is fast and efficient.
[0007] Stamp-perforated panels: Stamp holes are designed between panels, and the panels are separated by tearing or other methods along the stamp holes during separation. Its advantages include avoiding cutting marks on the panel edges like VCUT, resulting in a cleaner appearance and less impact on the structural strength of the panel edges. However, the design and manufacturing of the stamp holes require higher precision.
[0008] Bending machine: It uses upper and lower dies to precisely align the VCUT line and apply bending force to break it. The stress is relatively controllable and the efficiency is high.
[0009] However, most of the above processes require VCUT cutting before processing, necessitating at least one VCUT machine and other types of depaneling machines in the workshop. This results in a large footprint and high equipment costs. Therefore, it is necessary to integrate VCUT cutters and other types of cutters, such as milling cutters, into a single depaneling machine to perform more than one depaneling process. Utility Model Content
[0010] To address the issue that currently used PCB depaneling machines can only perform one process at a time and lack a cutting mechanism that can simultaneously support VCUT and other depaneling processes, a dual-head depaneling cutter with a ventilation switching mechanism is provided.
[0011] A dual-head slitting cutter with an exhaust switching mechanism includes a cutter head assembly, a dust collection assembly, and a displacement drive assembly. The cutter head assembly includes a first cutter head, a second cutter head, and a support base. The first and second cutter heads are respectively mounted on the support base via lifting slides. The displacement drive assembly is connected to the rear of the support base. The dust collection assembly includes a dust collection hood, a dust collection hose, and an exhaust switching box. The front ends of the first and second cutter heads are each fitted with a dust collection hood. The two dust collection hoods are respectively connected to the front end of the exhaust switching box via dust collection hoses. A switch baffle is provided on the inner side of the exhaust switching box corresponding to the outlets of the two dust collection hoses. The rear air passage of the exhaust switching box is connected to an industrial dust collector.
[0012] Furthermore, the outlets of the two suction hoses are connected side by side to the front end of the exhaust switching box, and the switch baffle is driven by a left and right sliding push rod. The upper and lower sides of the switch baffle are slidably fitted with sliding rails.
[0013] Furthermore, both ends of the switch baffle are provided with locking protrusions, and the inner side of the exhaust switching box is provided with locking grooves corresponding to the locking protrusions.
[0014] Furthermore, the length and width of the switch baffle are both greater than the diameter of the vacuum hose.
[0015] Furthermore, the first cutting head includes a circular VCUT cutter, with a vertical shaft connected above the circular VCUT cutter, and a dust collection hood covering the outer side of the circular VCUT cutter; the second cutting head includes a vertical end mill, with a dust collection hood covering the outer side of the vertical end mill.
[0016] Furthermore, the front ends of both the first and second blades protrude below the dust hood, and a ring-shaped brush is connected to the bottom of the dust hood.
[0017] Furthermore, the inner air passage of the dust collection hood is connected to an ion fan.
[0018] The advantages of this utility model are:
[0019] 1. The slitting cutter is equipped with different types of blades and has an integrated, switchable dust collection mechanism, which is highly integrated and occupies a small size.
[0020] 2. Different board separation processes can be completed in the same location, resulting in high work efficiency. Attached Figure Description

[0027] To address the issue that currently used PCB depaneling machines can only perform one process at a time and lack a cutting mechanism that can simultaneously support VCUT and other depaneling processes, a dual-head depaneling cutter with a ventilation switching mechanism is provided.

[0031] like Figures 1 to 3As shown, this embodiment provides a double-headed plate cutter with an exhaust switching mechanism, including a cutter head assembly 1, a dust collection assembly 2, and a displacement drive assembly 3. The cutter head assembly 1 includes a first cutter head 101, a second cutter head 102, and a support base 103. The first cutter head 101 and the second cutter head 102 are respectively mounted on the support base 103 via a lifting slide 4. The displacement drive assembly 3 is connected to the rear of the support base 103. The dust collection assembly 2 includes a dust collection hood 201, a dust collection hose 202, and an exhaust switching box 203. The front ends of the first cutter head 101 and the second cutter head 102 are each fitted with a dust collection hood 201. The two dust collection hoods 201 are respectively connected to the front end of the exhaust switching box 203 via the dust collection hoses 202. A switch baffle 5 is provided on the inner side of the exhaust switching box 203 corresponding to the outlet of the two dust collection hoses 202. The rear air passage of the exhaust switching box 203 is connected to an industrial dust collector.
[0032] The outlets of the two suction hoses 202 are connected side-by-side to the front end of the exhaust switching box 203. The switch baffle 5 is driven by a left-right sliding push rod 501, and sliding rails 502 are slidably fitted on both the upper and lower sides of the switch baffle 5. The single-piece switch baffle 5 acts as a simple air duct switching mechanism with fast operation. The sliding rails 502 improve the smoothness of the operation of the switch baffle 5.
[0033] During equipment operation, the first cutter head 101, the second cutter head 102, the displacement drive assembly 3, the lifting slide 4, and the left and right translation push rod 501 can be uniformly controlled by an industrial control computer. The displacement drive assembly 3 can be a multi-axis slide. After the displacement drive assembly 3 moves the cutter head assembly 1 above the circuit board to be separated, the first cutter head 101 or the second cutter head 102 is switched to cut the circuit board by the descent of the lifting slide 4. At this time, under the drive of the left and right translation push rod 501, the switch baffle 5 blocks the dust suction duct of the cutter head that is not descending, ensuring that the industrial dust collector only sucks dust from the working cutter head.
[0034] Both ends of the switch baffle 5 are provided with locking protrusions 503, and the inner side of the exhaust switching box 203 is provided with locking grooves 204 corresponding to the locking protrusions 503. The locking protrusions 503 and the locking grooves 204 can improve the positioning stability of the switch baffle 5.
[0035] The length and width of the switch baffle 5 are both greater than the diameter of the suction hose 202. The large switch baffle 5 ensures that the outlet of the suction hose 202 is completely blocked, preventing air leakage.
[0036] The first cutter head 101 includes a circular VCUT cutter, with a vertical rotating shaft 111 connected above it. A dust collection hood 201 covers the outer side of the circular VCUT cutter. The second cutter head includes a vertical milling cutter, also covered by a dust collection hood 201. This embodiment employs a dual-cutter head solution combining a VCUT cutter and a vertical milling cutter, facilitating processes such as milling residual portions after VCUT, creating stamp holes, or VCUT line folding plates.
[0037] The front ends of both the first cutter head 101 and the second cutter head 102 protrude below the dust collection cover 201, and a ring-shaped brush 6 is connected to the bottom of the dust collection cover 201. The soft ring-shaped brush 6 does not obstruct the cutting operation of the cutter head and can prevent dust generated during cutting from escaping to the outside of the brush. In addition, the ring-shaped brush 6 can play a certain role in wiping and cleaning when it moves on the surface of the circuit board.
[0038] The inner air passage of the dust extraction hood 201 is connected to an ion fan 7. Because the blade and the circuit board rub against each other during the cutting process, static electricity is easily generated, causing dust to adhere to the surface of the equipment or the circuit board. Therefore, the ion fan 7, a commonly used static electricity elimination device, is used to remove the static electricity around the blade and ensure that the dust can be quickly sucked away.
[0039] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
