Further, referring to fig. 3, fig. 3 is a schematic flow chart of a method for testing performance of a galvanometer according to a first embodiment of the present invention, where the method for testing performance of a galvanometer is applied to the device for testing performance of a galvanometer, and the method for testing performance of a galvanometer includes:
step S10, acquiring all reflection points reflected to the galvanometer performance test chart card by the galvanometer, and sequentially detecting whether each reflection point is in a preset effective area;
in this embodiment, different galvanometer performance test graphic cards are set according to different galvanometer types, and the vibration performance of the galvanometer is converted into an optical signal to be projected onto the galvanometer performance test graphic card, so that the galvanometer performance is determined according to a projected light spot (i.e., a projection point). Therefore, in the embodiment, the vibrating angle, the vibrating stability and the vibrating direction of the vibrating mirror can be visually detected through the vibrating mirror performance test chart. And the vibration of the vibrating mirror is converted into an intuitive optical signal, so that the performance of the vibrating mirror can be conveniently detected. And through the measurement according to the screen projection light spot, can indirect measurement galvanometer's swing angle, also can indirect measurement galvanometer's swing direction to judge whether equipment such as magnet or coil in the galvanometer has the mistake according to the measuring result. In addition, in the embodiment, the swing angle or swing direction of the galvanometer can be obtained through the light spot position of the observation screen, and the measurement mode is simple and convenient for production line test.
Therefore, in this embodiment, after the laser device emits the laser beam to the galvanometer through the circular hole of the screen, the galvanometer reflects the laser beam to the galvanometer performance test chart, and the galvanometer performance test chart forms reflection points according to the reflected laser beam, and because the galvanometer is in a vibration state, a plurality of reflection points exist in the galvanometer performance test chart, and the reflection points need to be detected in sequence, so as to determine whether the laser beam is in a preset effective area, and execute different operations according to different detection results.
In the embodiment, before the galvanometer vibrates, the oscillating angle of the galvanometer needs to be calculated, and the calculation formula of the technical oscillating angle α can be calculated according to the following formula.
Wherein, L is the offset distance of the projection point, Delta L is the swing angle tolerance of the galvanometer, and D is the shortest distance between the galvanometer and the galvanometer performance test chart. It should be noted that, in this embodiment, the galvanometer includes a biaxial galvanometer and a uniaxial galvanometer, so that the chart for testing galvanometer performance also includes a chart for testing biaxial galvanometer performance and a chart for testing uniaxial galvanometer performance, and L in the chart for testing biaxial galvanometer performance is different from the chart for testing uniaxial galvanometer performance, as shown in fig. 4, the chart includes a chart for testing biaxial galvanometer swing and a chart for testing uniaxial galvanometer swing, and each chart includes four preset effective areas, i.e., an area a, an area B, an area C and an area D, and a circular hole, so that light passes through the hole to the galvanometer. In the biaxial galvanometer swing test chart, L is calculated by firstly determining an AB line segment and then calculating the shortest distance from a circular hole to the AB line segment (or an AD line segment, or a DC line segment, or a BC line segment), namely L. In the uniaxial galvanometer swing test chart, the distance from the circular hole to the A area, the B area, the C area or the D area is directly taken as L. Therefore, the type of the galvanometer needs to be determined when calculating the swing angle of the galvanometer.
Step S20, if each of the reflection points is in a preset effective region, obtaining a reflection area of each of the reflection points, and sequentially comparing each of the reflection areas with the effective area of the effective region;
when it is found that each reflection point is within the preset effective region through judgment, the reflection area of each reflection point needs to be obtained, and the way of obtaining the reflection area may be directly performing measurement calculation through a measurement tool, and the specific obtaining way is not limited herein. Meanwhile, the area of the preset effective area needs to be acquired in the same manner as the reflection area. In the present embodiment, since the galvanometer is in a swinging state, and the positions of the projection points are also different, the number of the effective areas is multiple and is not limited to only one, and in the present embodiment, four effective areas are preferably provided, and each effective area does not include the position of the circular hole.
Therefore, when comparing the effective areas of the effective areas with the reflection areas in sequence, the effective area where the reflection point is located needs to be determined first, that is, when the effective area has an area a, an area B, an area C, and an area D, when the reflection point is found to exist in the area a by judgment, the area of the area a is obtained first, the reflection area of the reflection point is obtained, and then whether the reflection area is larger than the area is judged, and if so, it is determined that the angle of the vibrating mirror is abnormal or the vibrating mirror is unstable (there is overshoot or ringing). And in the same way, if any one of the B area, the C area and the D area has a reflection point, the judgment is carried out in the same way as the A area so as to determine whether the galvanometer has abnormality. When the projection point is not located in any of the areas a, B, C, and D, it can be considered that there is an abnormality in the galvanometer, such as an abnormality in the oscillating angle of the galvanometer.
But when one or more reflection points are found out to be not in the preset effective area in each reflection point through judgment, the abnormality of the galvanometer can be directly determined. The preset effective area can be a theoretical area of a projection point in the galvanometer performance test chart, which is set in advance by a user, and the number of the effective areas is multiple. The reflection area is the area occupied by the reflection points in the galvanometer performance test chart, and each reflection point has a corresponding reflection area. The effective area may be an area occupied by the effective area in the galvanometer performance test chart.
In step S30, if a target reflection area larger than the effective area exists in each of the reflection areas, it is determined that the galvanometer is abnormal.
When the target reflection area larger than the effective area exists in each reflection area through judgment, the existence of abnormity of the vibrating mirror can be directly determined, such as the abnormity of the swinging angle of the vibrating mirror. And when the reflection area of the reflection point is larger than the effective area of the effective area where the reflection point is located, the target reflection area is the reflection area of the reflection point.
In the embodiment, all the reflection points reflected to the galvanometer performance test chart card by the galvanometer are obtained, and whether each reflection point is in a preset effective area or not is sequentially detected; if all the reflection points are in a preset effective area, acquiring the reflection area of all the reflection points, and sequentially comparing all the reflection areas with the effective area of the effective area; and if a target reflection area larger than the effective area exists in each reflection area, determining that the galvanometer is abnormal. All reflection points reflected to a galvanometer performance test chart card by the galvanometer are obtained, and when each reflection point is in an effective area and a target reflection area with the reflection area larger than the effective area exists, the existence of abnormity of the galvanometer is determined, so that the accuracy of the galvanometer performance test is ensured, the vibration performance of the galvanometer is converted into optical signals to form the reflection points, the galvanometer performance test is carried out according to the reflection points, and the efficiency of the galvanometer performance test is also improved.

If the single-axis galvanometer is adopted, the galvanometer performance test chart is a single-axis galvanometer performance test chart. And determining the linear distance between the circular hole of the screen and a preset effective area according to different galvanometer performance test card types, namely determining L.
B, determining the shortest distance between the galvanometer and the galvanometer performance test graphic card, and calculating the galvanometer swing angle according to the preset galvanometer swing angle tolerance, the linear distance and the shortest distance;
because the galvanometer and the galvanometer performance test graphic card are in a parallel state, the shortest distance for obtaining the galvanometer and the galvanometer performance test graphic card can be the shortest straight-line distance D for directly obtaining the galvanometer and the galvanometer performance test graphic card, and then the galvanometer swing angle alpha is calculated according to the preset galvanometer swing angle tolerance delta L, namely:
and c, controlling the vibration mirror to swing according to the vibration mirror swing angle, and acquiring all reflection points reflected to the vibration mirror performance test chart card when the vibration mirror swings.
After the oscillating angle alpha of the oscillating mirror is obtained, the oscillating mirror expression can be directly controlled according to the oscillating angle alpha of the oscillating mirror, all reflection points reflected on an oscillating mirror performance test chart card when the oscillating mirror oscillates are obtained, and if the reflection points are in a preset effective area, the oscillating direction of the oscillating mirror is determined to be correct.
