Description

Technical Field

[0001] The invention relates to the technical field of laser level calibration, and particularly to a laser level calibration device. Background Art

[0002] A laser level is a household hardware decoration tool that uses a laser beam instead of manual reading. The laser beam emitted by the laser is guided into the telescope tube so that it emits a horizontal laser beam along the sighting axis. It generally has the functions of measuring the flatness of the plane, outputting laser vertical planes and horizontal points, and measuring whether the plane is horizontal. The laser level mainly consists of two parts: a base and a level body. In order to ensure that the emitted laser beam is horizontal and vertical and avoid affecting the selection and construction of the decoration reference surface, it is necessary to manually project the laser beam onto the wall through three telescope tubes for manual adjustment. During the adjustment process, manual adjustment is prone to inaccurate accuracy, time-consuming and labor-intensive manual adjustment, and other problems. Therefore, the horizontal and vertical accuracy of the laser level calibration line cannot be well guaranteed, which affects the progress and quality of the decoration construction.

[0027] In this embodiment, Figure 2 、 Figure 3The fixed frame base 1 and the fixed manipulator device 2 are fixed to the center of the large base 6 through threaded connection, and the carrier adjustment plate 11 is provided with a transverse positioning groove for easy mobile installation; Figure 3 The laser level 7 is placed in the carrier bottom plate 8 to fix the shell of the laser level 7. At this time, the movement of the laser level 7 is still in an unfixed state and needs to be fixed by fixing the manipulator 2.

[0028] The clamping jaws 12 and the thin cylinder 13 are mounted on the linear slider of the first linear guide 14, so that the clamping jaws are aligned with the fixed groove of the internal movement of the laser level 7. The worm gear 16 is driven by the stepping motor 18, and the linear bearing 17 is used to vertically raise the platform on which the first linear guide 14 is mounted until the height of the clamping jaws and the movement of the laser level 7 is consistent, and then stop. The slider of the first linear guide 14 is then pushed forward by the first double-acting cylinder 15, causing the clamping jaws 12 to move as a whole toward the Y-axis. At the same time, the thin cylinder 13 pushes the clamping jaws 12 to clamp the internal movement of the laser level 7, so that the internal movement of the laser level 7 is in a fixed state and does not shake during the adjustment process.

[0029] At this time, the laser level 7 is in the starting state, showing two mutually perpendicular rays on the debugging wall. One of the rays is set as a horizontal ray and the other as a vertical ray. The visual camera 22 is used to determine whether it is on the baseline.

[0030] The visual camera assembly 3 is installed on the right rear of the fixed frame base 1 and the fixed manipulator 2 through a threaded connection, so that the lens of the visual camera 22 is installed with the center line of the laser level 7 as its installation reference. The external visual engineering software can be used to detect whether the horizontal line and the vertical line of the laser level 7 are aligned with the set reference line. If they are not on the set reference line, it is necessary to adjust the calibration manipulator device 4 for adjustment.

[0031] When both the left and right adjustment and calibration manipulators are in the Figure 5 The adjustment and calibration manipulator device can only operate when it is in the initial position shown. The visual adjustment camera 39 on the adjustment manipulator claw component 4 identifies the position of the adjustment knob of the laser level 7. When it is not in its position, the first servo motor then moves the adjustment bit 35 in the adjustment manipulator claw component 4 to the adjustment knob position of the laser level 7 through the x-axis transmission component 30, the y-axis transmission component 29 and the z-axis transmission component 28. Then, the second servo motor 37 is pushed by the second double-acting cylinder 38 to make the adjustment bit 35 press against the adjustment knob of the laser level 7. The adjustment bit 35 is controlled to rotate by the second servo motor 37, and at the same time, the vertical and horizontal rays on the wall are observed to slowly coincide with the reference line. When they are completely coincident, the laser level 7 is in the calibration completed state.
