その目的とする。(Problem to be solved by the invention) By the way, in the case of the above-mentioned lead frame deburring device using ultra-high pressure water, if the conveyor for conveying lead frames stops for some reason, 500 to 3000
Ultra-high pressure water of Kg/ cm2 hits the same spot on a stopped lead frame the entire time it is stationary, and even if the burr is removed, it may damage the vital package. In this case, you can immediately stop the supply of ultra-high pressure water to the injection nozzle, but the pressure will not drop suddenly even if you stop the pump of the ultra-high pressure water source, and if you close the pipe, The water hammer effect caused by the sudden closure of water flow pipes has become even more likely to cause accidents that damage the ultra-high pressure water pipe system. This design prevents the lead frame package from being continuously sprayed with ultra-high pressure water even if a feed abnormality occurs on the lead frame transfer conveyor, such as a stoppage accident, and even if the supply of ultra-high pressure water suddenly stops, the high-pressure water piping The purpose of the present invention is to provide a lead frame deburring device using ultra-high pressure water that does not cause any failures in the road.

An ultra-high pressure water injection nozzle 4 is provided, and an ultra-high pressure water source 5 is provided.
The ultra-high pressure water pipe 6 to the injection nozzle 4 is connected to a power-operated discharge valve 7 that branches off before the injection nozzle 4.
is provided, and the ultra-high pressure water injection path O-O of the injection nozzle 4 is
A shielding plate 9 of injected ultra-high pressure water is installed across the air-driven cylinder 8, which enters and exits in response to the operation of the air-driven cylinder 8. The side surface of the conveyor rotation roller 3', which is a device of the conveyor 3, or the conveyor 3
A conveyor feed abnormality detector (for example, an image sensor) 13 is installed above the conveyor, and when the detector 13 detects an abnormality in the rotation of the roller 13, such as a stoppage, the automatic controller 14 detects the power-operated on-off valve 12.

Now, the conveyor rotation roller 3' of the conveyor 3 device rotates and the lead frame 1 on the conveyor 3 is rotated.
When the lead frame 1 is transferred, ultra-high pressure water is injected from the injection nozzle 4 onto the lead frame 1 to remove any burrs or seepage.

水源５のポンプを停止することは勿論とする。 If an abnormality occurs in the feeding of the conveyor 3 for some reason, for example, it stops, the detector 13 detects the stoppage of rotation of the conveyor rotation roller.
actuates the automatic controller 14, which sends a signal to the power operated on-off valve 12 and the power operated release valve 7 to open each valve 12,7. As a result, the piston 16 of the air-driven cylinder 8 resists the elasticity of the coil spring 15 and projects the ultra-high pressure water shielding plate 9 into the ultra-high pressure water injection path O-O of the injection nozzle 4.
Remove the ultra-high pressure water jet and power operated release valve 7.
By opening the ultra-high pressure water source 5, most of the ultra-high pressure water from the ultra-high pressure water source 5 is released from the discharge valve 7 to the outside of the piping path 6, and even if water flows into the injection nozzle 4, only a small amount of water that has become low pressure will go. , the conveyor 3 stops, and therefore, even if the lead frame 1 stops below the injection nozzle 4, the jet of ultra-high pressure water will not be continuously sprayed at one location on the lead frame 1. . Incidentally, after opening the discharge valve 7, it goes without saying that the pump of the ultra-high pressure water source 5 is stopped.

る。 Then, when conveyor 3 starts operating again, detector 1
3 sends a signal to the automatic controller 14 again to close the power-operated on-off valve 12 and the power-operated release valve 7, so the piston 16 of the air-driven cylinder 8 returns to its original state due to the elasticity of the coil spring 15, and the ultra-high pressure water shield plate 9
is drawn in from the ultra-high pressure water injection path O-O, so the ultra-high pressure water jet again injected from the injection nozzle 4 passes below the injection nozzle 4 into the lead frame 1.
It is then sprayed again to perform the prescribed deburring work.

Since this device has the above-mentioned configuration and operation, even if the conveyor device for the packaged lead frame 1 suddenly stops rotating, the lead frame 1 on the stopped conveyor 3 will be moved to one place. It is possible to completely prevent damage to the package 2 of the lead frame 1 due to continuous spraying of ultra-high pressure water, and even if the supply of ultra-high pressure water to the injection nozzle 4 is stopped, water hammer will not occur. There is no concern that ultra-high pressure water piping will be damaged due to the action.
