  The above-mentioned laser marking device can be used as long as the main body is inclined within a certain angle, but the irradiable line laser (hereinafter referred to as “line”) is only a horizontal line and a vertical line, If it is desired to irradiate an intentionally inclined line, the line cannot be operated because the line is turned off or blinks when the main body is inclined. In the case of line flashing, the line can be recognized depending on the flashing speed, but the internal laser unit always stops at somewhere in the main body, and therefore, the line accuracy is disturbed by the impact when hit. For this reason, it was necessary to be able to irradiate an inclined line while restraining the gimbal mechanism.

  Some laser marking devices employ an electronic gimbal system that can tilt the laser unit with a tilt sensor and motor, but the structure is complex and very expensive.

  Accordingly, an object of the first invention is to provide an inexpensive laser marking device capable of irradiating an inclined line with a simple configuration.

  In addition, in order to irradiate the laser beam by tilting the main body with a conventional laser marking device, the main body is tilted after fixing the gimbal mechanism by some method. At this time, the laser unit is moved to the stand by its own weight. In contrast, the laser beam may be displaced from the reference line, which may cause erroneous work and / or frequent readjustment, resulting in poor work efficiency. It was.

  Accordingly, an object of the second invention is to provide a laser marking device capable of preventing a work efficiency drop due to a misalignment due to a deviation of an inclination line and frequent readjustment.

In order to achieve the above object, the present invention provides a main body configured by providing a cover on a stand portion, a laser unit swingably accommodated in the cover of the main body, and the laser unit in a vertical posture. A gimbal mechanism for holding, a fixing means for fixing the laser unit, and an inclination sensor for detecting the inclination of the main body, and the line laser beam from the laser unit when the main body is inclined beyond a limit angle. In the laser marking device in which the inclination state is notified by the first power switch that is turned off when the laser unit is fixed by the fixing means, and a second power switch that is different from the first power switch,
By turning off the first power switch and turning on the second power switch, line laser light is irradiated when the main body is tilted beyond the limit angle .

Further, when the second power switch is on, the detection signal from the tilt sensor is invalidated.

Further, the first power switch is turned off when the laser unit is fixed vertically or nearly vertically by the fixing means.

Further, when the laser unit is irradiating an inclined line, the inclined line is blinked at a constant or arbitrary time interval.

The cover is provided so as to be rotatable with respect to the stand part, and provided with a rotation fixing means for fixing the rotation of the cover with respect to the stand part .

The rotation fixing means fixes the cover to the stand portion when the main body is tilted to irradiate an inclined line.

Further, the rotation fixing means fixes the cover to the stand portion when the first power switch is turned off and the second power switch is turned on to irradiate the inclined line.

Further, the rotation fixing means is constituted by a bolt screwed into the stand portion.

Further , an elastic body is disposed on a portion of the cover that receives the tip of the bolt.

Further, the rotation fixing means is constituted by a bolt screwed to the stand portion and the cover.

Further, the rotation fixing means is constituted by a solenoid provided on one of the stand part or the cover and a concave part in which a rod of the solenoid is selectively engaged.

Further, the solenoid operates in conjunction with turning on the second switch.

Further, the rotation fixing means is constituted by an insertion hole formed in the stand part and the cover, and a stopper inserted through the insertion hole.

Further, the rotation fixing means is constituted by a gap formed in the stand part and the rotating part of the cover, and a fixing member inserted into the gap.

Further, the rotation fixing means is constituted by a band wound around the outer periphery of the rotating part of the stand part and the cover.

Further, the rotation fixing means is constituted by a hook provided on one of the stand part and the cover and a pin provided on the other.

According to the present invention, it is possible to irradiate an inclined line inclined at an arbitrary angle with a simple configuration in addition to a horizontal or vertical line.

In addition, when the first power switch is off, that is, when the laser unit is fixed, the second power switch is turned on so that the laser beam can be irradiated. It is possible to irradiate the inclined line with high accuracy without receiving the light.

Also, when the second power switch is turned on, the detection signal from the tilt sensor is disabled, so the tilt sensor detects the tilt when the laser unit is fixed in a tilted state exceeding the limit angle. Thus, the inclined line can be stably irradiated without turning off the laser beam.

Also, when the main body is tilted to irradiate the tilt line, the first power switch is turned off and the laser unit is fixed in a vertical or nearly vertical posture. A stable inclined line can be irradiated without being turned off or blinking.

In addition, when the laser unit is irradiating the tilt line, the tilt line can be flashed at a constant or arbitrary time interval to inform the user that the tilt line is being irradiated. It is possible to prevent the occurrence of a malfunction of mistaking it as a vertical line.

In addition, since the fixing means for fixing the horizontal rotation on the stand part of the cover is provided, the laser unit will be self-weighted if the horizontal rotation of the cover is fixed by the fixing means when tilting the main body and irradiating the inclined line from the laser unit. Therefore, it does not rotate with respect to the stand part. For this reason, the laser beam does not shift with respect to the reference line, the occurrence of erroneous work is prevented, and frequent readjustment is not required, so that work efficiency is improved.

Further, it is possible to irradiate the inclined line with high accuracy by preventing the laser unit from rotating due to its own weight.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the horizontal rotation of the cover relative to the stand can be fixed by turning the bolt and pressing the tip against the cover. In addition, it is possible to prevent a reduction in work efficiency due to erroneous work accompanying frequent deviation of the tilt line and frequent readjustment.

In addition, since the elastic body is provided in the portion of the cover that receives the tip of the bolt, damage to the cover side due to the contact of the tip of the bolt can be prevented, and it occurs at the contact portion between the elastic body and the tip of the bolt. By increasing the frictional force, the horizontal rotation of the cover can be more reliably fixed.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the cover can be fastened to the stand portion by screwing the bolt that is screwed into the stand portion into the screw hole on the cover side. Therefore, horizontal rotation of the cover can be reliably prevented.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, for example, energize the solenoid provided on the cover side to push down the rod and engage its tip with the recess of the stand By doing so, the horizontal rotation of the cover with respect to the stand portion is securely fixed, and it is possible to prevent the work efficiency from being lowered due to the misalignment due to the deviation of the tilt line and frequent readjustment.

In addition, since the solenoid is operated in conjunction with the turning on of the second switch, the work efficiency for preventing the rotation of the laser unit (cover) is enhanced.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the horizontal rotation of the cover with respect to the stand part can be ensured by inserting a stopper into the insertion hole formed in the stand part and the cover. Since it is fixed, it is possible to prevent a work efficiency from being lowered due to an erroneous operation due to a deviation of the inclined line or frequent readjustment.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the horizontal rotation with respect to the stand of the cover is ensured by inserting a fixing member into the gap formed in the rotating part of the stand and the cover. Therefore, it is possible to prevent a work efficiency from being lowered due to an erroneous operation due to a deviation of the inclined line or frequent readjustment.

Also, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the horizontal rotation of the cover with respect to the stand portion can be reliably fixed by winding the band around the outer periphery of the stand portion and the rotating portion of the cover. For this reason, it is possible to prevent a work efficiency from being lowered due to erroneous work accompanying frequent deviation of the tilt line and frequent readjustment.

In addition, when tilting the main body of the laser marking device and irradiating the tilt line from the laser unit, the cover stand can be achieved by engaging the hook provided on one of the stand part and the cover with the pin provided on the other. Since the horizontal rotation with respect to the portion is securely fixed, it is possible to prevent a work efficiency from being lowered due to an erroneous operation due to the deviation of the inclined line or frequent readjustment.
