Description

一种用于扫平仪的整平***及一种扫平仪A leveling system for a leveler and a leveler 技术领域Technical field

背景技术Background technique
在工程建设、室内装潢等领域，常常用扫平仪进行水平定位，扫平仪主要是通过激光头的高速旋转使可视光快速移动并利用人的视觉暂留在墙壁上形成连续激光线。In the fields of engineering construction, interior decoration, etc., a leveler is often used for horizontal positioning. The leveler mainly uses the high-speed rotation of the laser head to make visible light move quickly and use human vision to temporarily stay on the wall to form a continuous laser line.
目前的扫平仪通常具有垂直工作模式和水平工作模式这两种工作模式。在水平工作模式中，仪器正常摆放，仪器通过自身的整平***进行整平，从而投出水平的一圈激光准直线；在垂直工作模式中，使用者将仪器旋转90°放置(倒下放置)，仪器需要投出垂直的一圈激光准直线。现有扫平仪通常没有设置在垂直工作模式中的整平***，扫平仪在垂直工作模式中，需要放置到水平的平面上，才能投出垂直的激光准直线。当扫平仪放置的平面倾斜时，扫平仪难以投出垂直的激光准直线。Current swingers usually have two working modes, a vertical working mode and a horizontal working mode. In the horizontal working mode, the instrument is placed normally, and the instrument is leveled by its own leveling system, thereby projecting a horizontal circle of laser alignment; in the vertical working mode, the user rotates the instrument 90° and places it (falling down Place), the instrument needs to project a vertical circle of laser alignment. The existing swinger usually does not have a leveling system set in the vertical working mode. In the vertical working mode, the swinger needs to be placed on a horizontal plane to project a vertical laser alignment. When the plane on which the swinger is placed is inclined, it is difficult for the swinger to project a vertical laser collimation line.
因此，需要开发一种能够在垂直工作模式和水平工作模式中都能对扫平仪进行高精度整平的整平***及扫平仪。Therefore, it is necessary to develop a leveling system and a leveling instrument that can perform high-precision leveling of the leveling instrument in both the vertical working mode and the horizontal working mode.

进一步地，参见附图2，扫平仪处于垂直工作模式，所述第一传感单元100包括：水准泡120、发光元件110、第一感光元件130、第二感光元件140，处理单元。所述水准泡120内具有液体和气泡。所述发光元件110优选为发出红外信号的红外LED，设置于水准泡的下侧。所述第一感光元件130、第二感光元件140优选为光敏二级管，设置于所述水准泡120上侧的两端，用于接收发光元件110发出的穿过所述水准泡120的光信号，并转换为电信号输出。处理单元，用于根据两个感光元件输出的电信号判定水准泡120是否平衡，并判定所述机芯的主光轴与水平平面的角度偏差。具体地，水准泡120下侧的红外LED发出的红外信号被水准泡120上侧左右两端的光敏二级管接收，两个光敏二级管接收红外信号输出电流到处理单元，处理单元根据两个光敏二级管接收红外信号输出电流的差值判定水准泡120是否平衡，并判定所述机芯的主光轴与水平平面的角度偏差。当所述水准泡120平衡时，水准泡120内气泡位于中间位置，两个光敏二级管接收的红外信号强度相等，两个光敏二级管输出的电流相等；当所述水准泡倾斜(即不平衡)时，水准泡120内气泡位置偏移，两个光敏二级管接收的红外信号强度不相等，两个光敏二级管输出的电流不同，根据电流的差值可以判定机芯的主光轴与水平平面的角度偏差。所述第一传感单元100被配置为，当水准泡120平衡时，机芯主光轴与水平平面重合。由于第一传感单元100与机芯固定连接，从而只要通过第一整平机构300根据第一传感单元100的感应结果调整机芯姿态，使水准泡120平衡，就可以使机芯的主光轴与水平平面重合，扫平仪在目标物体上形成的参考线为竖直线(即铅垂线)。在一些实施例中，所述第一传感单元100可以为电容式或电感式的水平仪，只要对其进行配置，使其水平时，机芯的主光轴与水平平面重合即可。Further, referring to FIG. 2, the sweeper is in a vertical working mode, and the first sensing unit 100 includes: a vial 120, a light-emitting element 110, a first photosensitive element 130, a second photosensitive element 140, and a processing unit. The level bubble 120 contains liquid and bubbles. The light-emitting element 110 is preferably an infrared LED that emits an infrared signal, and is arranged on the lower side of the level bubble. The first photosensitive element 130 and the second photosensitive element 140 are preferably photosensitive diodes, which are arranged at both ends of the upper side of the level bubble 120, and are used to receive the light emitted by the light emitting element 110 passing through the level bubble 120 Signal, and converted to electrical signal output. The processing unit is used to determine whether the level bubble 120 is balanced according to the electrical signals output by the two photosensitive elements, and to determine the angular deviation between the main optical axis of the movement and the horizontal plane. Specifically, the infrared signal emitted by the infrared LED on the lower side of the level bubble 120 is received by the photosensitive diodes at the left and right ends of the upper side of the level bubble 120. The two photosensitive diodes receive the infrared signal and output current to the processing unit. The difference between the output current of the photosensitive diode receiving the infrared signal determines whether the level bubble 120 is balanced, and the angular deviation between the main optical axis of the movement and the horizontal plane. When the vial 120 is balanced, the bubble in the vial 120 is in the middle position, the infrared signal intensity received by the two photosensitive diodes is equal, and the current output by the two photosensitive diodes is equal; when the vial is inclined (ie When unbalanced), the position of the bubble in the vial 120 is shifted, the intensity of the infrared signal received by the two photosensitive diodes is not equal, and the currents output by the two photosensitive diodes are different. According to the difference of the currents, the main movement of the movement can be determined. The angular deviation of the optical axis from the horizontal plane. The first sensing unit 100 is configured such that when the vial 120 is balanced, the main optical axis of the movement coincides with the horizontal plane. Since the first sensing unit 100 is fixedly connected to the movement, as long as the first leveling mechanism 300 adjusts the movement posture according to the sensing result of the first sensing unit 100 to balance the level bubble 120, the main movement of the movement can be made The optical axis coincides with the horizontal plane, and the reference line formed by the swinger on the target object is a vertical line (that is, a plumb line). In some embodiments, the first sensing unit 100 may be a capacitive or inductive level, as long as it is configured so that when it is level, the main optical axis of the movement coincides with the horizontal plane.

Its configuration is similar to that of the first sensing unit 100. The difference is that the second sensing unit 200 is configured such that when the level bubble is balanced, the main optical axis of the movement is perpendicular to the horizontal plane, that is, the The vertical lines coincide or are parallel. Specifically, the level bubble, the light emitting element, and the two photosensitive elements of the second sensing unit 200 may be arranged at 90° relative to the first sensing unit 100. The second sensing unit 200 directly senses the angular deviation between the plane perpendicular to the main optical axis and the horizontal plane, that is, the angular difference between the main optical axis and the vertical line, and the angular deviation between the plane perpendicular to the main optical axis and the horizontal plane. The sum of the angular deviation between the main optical axis and the horizontal plane is 90°, and the second sensing unit 200 is equivalent to sensing the angular deviation between the main optical axis and the horizontal plane. In some embodiments, the second sensing unit 200 may be a capacitive or inductive level, as long as it is configured so that when it is horizontal, the main optical axis of the movement is perpendicular to the horizontal plane.

The first leveling mechanism 300 is used to adjust the angle between the main optical axis of the movement and the horizontal plane according to the sensing result of the first sensing unit 100 so that the main optical axis of the movement coincides with the horizontal plane. The second leveling mechanism 400 also includes a leveling motor, a screw rod, and a screw sleeve. The arrangement is basically the same as that of the first leveling mechanism 300, which will not be repeated here. The difference is that the second leveling mechanism It is used to adjust the angle between the main optical axis of the movement and the horizontal plane according to the sensing result of the second sensing unit 200 so that the main optical axis of the movement is perpendicular to the horizontal plane.
