advertising engraving machine equipment figure
CNC machinery co. , LTD. , integrating research, development, manufacture various types of woodworking advertising engraving machine | jade stone carving machine | | metal mold engraving machine series of optical fiber laser five-axis robot | | styrofoam CNC mortise and tenon joint processing center production line | | customize household such as all kinds of CNC engraving machine series, welcome to inquire!
we are in the use of advertising engraving machine if no note is easy to appear some fault, especially in starting the boot is very important. Let's take a look at advertising engraving machine startup of common problems and corresponding solutions:
failure:
the machine can not run boot device. Found in check the maintenance, the power tube is damaged, due to lost the role of the tube, thought is the front drive power, change the power tube, after electrify, power tube burned again and change of the pipe is easy to damage. Fault analysis:
at the beginning of analysis of the power tube fuse, advertising engraving machine because the pipe for step motor drive power, step motor for high voltage starting, therefore to accept high voltage large current. Static inspection, found that pulse annular divider circuit, the power supply to the side resistance is very small, but also not short circuit. According to the number of components in circuit power supply to the side resistance and power consumption analysis should not be so small, so doubt existing components of the circuit to be damaged.
many domestic engraving machine said their carving machine with floating head but some floating only - of the cutting tools A simple knife nose, used to pin processed objects, less than the real role, or motor too heavy floating up, or machined surface scratches. Floating head just as its name implies is the carving plane, can fluctuate within a certain range. Spindle on the Z axis is sliding up and down, pay attention to when using the floating head to adjust the distance of the cutting head and the tip, float can be carved on large area of the uneven plane, while keeping a uniform depth of the engraving.
or motor power is not enough that has a problem. CNC machinery equipment co. , LTD. , after the development of research, have solved the problem, with high power of the motor, and the floating part is only the motor rotor, so use RT4500 moment passes, there is no problem two-tone.
at present, the design has applied for national patent. Found to have abnormal heating chip. After power will cut off the power supply pin of this chip and electricity. Static checking, the power supply to the resistance increase should belong to normal. Measuring the chip power to the ground resistance is small. Check the chip model, is a non-standard models, numerous manual to the circuit analysis, confirmed its for main components of the plate, the annular pulse distributor. Fault solution:
in the first place, want to confirm that the problem of the chip. Then in withstand voltage current power is pretty stepper motor power drive pipe.
second, after electrify, leds are bright, namely each winding are electricity, it is not meet the requirements of the line input step pulse response, thus confirm the chip has been damaged. Restore the chip power supply pins, using leds to replace stepping motor's winding circuit simulated load.
but not on the chip market, drive casing under the condition of space allows, using the combination circuit which USES existing D flip-flop at hand and the combination of the nand gate design an annular pulse generator, production on a small PCB, removal of the original chips will small PCB by pin is installed on the original chip bonding pad.
still using light-emitting diodes as simulation load, after electrify plus one step pulse according to the phase sequence in turn to shine.
in the end, the removal of a simulated load, access to the host, electricity, equipment running normally.
engraving machine appear afore-mentioned problems, must not be themselves to remove the motor spindle, need to slowly to find the reason, don't be penny wise and pound foolish! You must be careful a little later in the use of it.
