Embodiment example 2
[0051] Consists of the following parts:
[0052] A strobe lighting device, an imaging delivery device composed of at least one pair of lenses, an image sensor, a synchronization signal, a modulator, and a monitoring device.
[0053] The above cases 1 and 2 are triggered by periodic synchronous trigger pulses, and the images formed are images corresponding to a fixed position on the circumference of the thin rod. The invention point is to change the strobe time by changing the trigger time of the trigger pulse , to collect images at different positions (G position or other positions) on the circumference of the thin rod, but always display the image of a specific fixed position on the circumference of the thin rod.
[0054] 5. Implementation case 3: Quickly detect all the holes on the circumference ----- form a complete image, the trigger pulse start time (trigger edge) is the trigger pulse start time (trigger edge) of the synchronous pulse,
[0055] Divide N equal parts by th...

The invention discloses a monitoring device for circumferentially-distributed holes of a thin rod, which is mounted at a punching section of a punching machine and comprises a stroboscopic lighting device, a monitoring device, a controller and a control device, and is characterized in that the stroboscopic lighting device is used for triggering flash lighting according to a synchronizing signal; the image sensor is used for starting to shoot a thin rod surface image according to the synchronizing signal; the synchronizing signal is used for reflecting the running speed and running position information of the thin rod object; the modulator is used for receiving the synchronizing signal and processing the input synchronizing signal, including setting parameters, calculating the running cycle of the thin rod, calculating the rotating cycle of the thin rod, calculating N equal parts of duration of the rotating cycle, and forming trigger pulse output after setting n equal parts of duration delay on the input synchronizing signal; and the monitoring device is used for carrying out data processing and / or displaying on the acquired information of the image sensor. The device can realize long-time continuous observation of the condition of a certain perforation distributed on the circumference of a thin rod object, and is especially suitable for equipment maintenance, fault elimination and in-depth study of perforation.
Description
Technical field: [0001] The invention belongs to the technical field of laser drilling, and in particular relates to a monitoring device for holes distributed in the circumference of thin rods and a matching punching machine. Background technique: [0002] For a long time, it has been a conventional technical solution to judge the circumferential punching of thin rod objects by using ventilation degree detection. This technical solution is to reflect the change of ventilation degree by detecting the change of ventilation air pressure formed by the thin rod after punching. However, due to the hysteresis of air pressure changes, this scheme has the disadvantage that it cannot accurately reflect the specific situation of each thin rod perforation. Chinese patent ZL201810341183.1 discloses a method of detecting the flame generated by perforation, and indirectly reflecting the situation of the hole through parameters such as flame height and diameter, which is also an indirect de...
