Examples

With reference to fig. 1, this embodiment provides a circuit board dividing and cutting machine, including dividing cutter 1, 1 overcoat of dividing cutter is equipped with knife pouch 2, just divide 1 cutting portion protrusion of cutter 2 lower extremes of cutter pouch, 2 lower extremes of cutter pouch are equipped with jet-propelled 21 and suction port 22, jet-propelled 21 with suction port 22 branch is located 2 width direction's of cutter pouch both ends.

The existing circuit board is cut in two ways, one is that a V-shaped groove is directly formed in a mother board by a cutter, so that after circuit welding is completed in the later period, the circuit board is manually broken into a single finished product, and the other is that a sawtooth cutting knife is directly adopted, and a mother mark is directly cut into a plurality of circuit boards which accord with the design size. Wherein, the mode of adopting the cutting of sawtooth cutting knife, the powder that produces is less, more, is difficult to handle.

This embodiment is mainly to the cutting machine of plank is cut to the sawtooth cutting knife, that is to say, the branch cutter 1 that this example provided is the sawtooth cutting knife, is equipped with the rotatory driving motor of drive cutting knife simultaneously to divide cutter 1 to rotate around self axis in the broach shell 2, and broach shell 2 fixes on driving motor.

Referring to fig. 2, the present embodiment is provided with a tool post 6 to mount a driving motor for driving the slitting knife 1 to rotate. In the slitting process, a mode that the conveying mechanism drives the circuit board to move can be adopted, and a mode that the driving mechanism drives a driving motor of the slitting knife 1 to move can also be adopted. It should be noted that the moving direction of the cutting blade 1 is parallel to the radial direction thereof.

Because the circuit board is usually fixed on the workbench 5 through a clamp, the mode of driving the driving motor of the slitting knife 1 to move is more energy-saving. Therefore, in the present embodiment, the tool post 6 is provided with a linear driving mechanism 61, and the linear driving mechanism 61 is used for driving the slitting knife 1 to move longitudinally or transversely. The moving direction of the splitting cutter 1 can be set according to actual requirements, for example, a part of circuit boards only need to be transversely cut or longitudinally cut, and when the transverse and longitudinal cutting is needed, the cutting can be completed by two splitting machines.

It can be understood that the linear driving mechanism 61 can be a synchronous pulley mechanism, a rack-and-pinion mechanism, a chain-and-sprocket mechanism, etc. driven by a motor, or can be a sliding table cylinder, etc., and in this example, the linear driving mechanism 61 is a screw-and-slider mechanism driven by a motor for simplifying the mechanism and ensuring the driving precision and self-locking performance of the linear driving mechanism 61.

Simultaneously, this embodiment still includes air compressor machine 3 and negative-pressure air fan 4, 3 exports of air compressor machine with 21 inlet end links to each other are chewed in the jet-propelled to in direct for the jet-propelled 21 high-pressure gas that provides of chewing, negative-pressure air fan 4 with suction mouth 22 links to each other, so that suck the gas in the broach shell 2 through negative-pressure air fan 4. Normally, filters are provided directly at the negative pressure fan 4 and the cutter housing 2 to prevent resin powder from directly entering the negative pressure fan 4.

In order to reduce the gap between the cutter sleeve 2 and the mother board when the mother board is cut, a gasket 23 is arranged at the lower end of the cutter sleeve 2 to prevent resin powder from directly escaping from the cutter sleeve 2 and the mother board.

Preferably, the gasket 23 is made of teflon, so that the self-lubricating property of the teflon is utilized to reduce the friction force of the gasket 23 when the gasket moves relative to the motherboard.

In order to reduce the positive pressure between the gasket 23 and the motherboard, the gasket 23 is connected with the cutter sleeve 2 through a flexible connecting sheet 24, so that the friction force when the gasket 23 moves is further reduced.

Preferably, the flexible connecting sheet 24 is a silicone sheet.

In addition, it is understood that the present embodiment further includes a work table 5, the work table 5 is provided with a plurality of feed grooves 51 to accommodate the lower end of the slitting blade 1 by feeding to the groove, so as to prevent the work table 5 from interfering with the movement of the slitting blade 1, and at the same time, the resin powder generated from the lower end surface of the mother plate can be collected by the feed grooves 51, and the feed grooves 51 are connected to the negative pressure fan 4 so as to timely suck the resin powder in the feed grooves 51 by the negative pressure fan 4.

When the cutting device is used, a circuit board is clamped on the workbench 5, the cutter path 51 covers the moving path of the cutting knife 1, then the cutting knife 1 is driven to rotate, and the linear driving mechanism 61 drives the cutting knife 1 to move longitudinally or transversely, so that a mother board is cut into a plurality of circuit boards according to the set size.

When cutting, high-pressure gas is input into the air injection nozzle 21 by the air compressor 3, and the high-pressure gas is output to the contact part of the cutting part of the slitting knife 1 and the circuit board through the air injection nozzle 21 so as to blow up the resin powder attached to the slitting knife 1 and the circuit board and suspend in the knife sleeve 2. Meanwhile, the negative pressure fan 4 provides negative pressure for the suction port 22 so as to draw away the resin powder, and the air injection nozzle 21 and the suction port 22 are respectively arranged at the two ends of the width direction of the knife sleeve 2, so that the suction port 22 can not influence the air injection of the air injection nozzle 21.

Consequently, this embodiment can in time clear away the resin powder that produces when the circuit board is cut, avoids the resin powder suspension in the workshop to improve workshop environment, avoid resin powder to cause the influence to operating personnel's health.

The foregoing is only a preferred embodiment of the present invention, and the present invention is not limited thereto in any way, and any simple modification, equivalent replacement and improvement made to the above embodiment within the spirit and principle of the present invention still fall within the protection scope of the present invention.
