[0030] Reference Figure 1 , the embodiment of the present application provides a dry window inspection device, comprising:
[0031] A dry window mounting seat 110, the dry window mounting seat 110 is used to mount a dry window, and the dry window is mounted with a first plane mirror L1 and a second plane mirror L2;
[0032] A light source module 120, which is disposed on one side of the dry window mounting base 110, and is used to emit light to the first plane mirror L1 and the second plane mirror L2 to form an emission light path;
[0033] The first target 130 is disposed on one side of the light source module 120, and the light source module 120 is located between the dry window mounting seat 110 and the first target 130; the first plane mirror L1 reflects light to the first target 130 to form a first reflected light path; the second plane mirror L2 reflects light to the first target 130 to form a second reflected light path.
[0034] According to the dry window inspection device of the embodiment of the present application, at least the following beneficial effects are achieved: when the dry window inspection device of the present application is used, the light source module 120 is used to emit light to the first plane mirror L1 and the second plane mirror L2 to form an emission light path; the first plane mirror L1 reflects the light to the first target 130 to form a first reflection light path; the second plane mirror L2 reflects the light to the first target 130 to form a second reflection light path. Through the position where the first reflection light path intersects with the first target 130 and the position where the second reflection light path intersects with the first target 130, it is possible to determine whether the angle between the two plane mirrors of the dry window meets the preset angle range.
[0035] Specifically, refer to Figure 2 , plane represents the second target 140; O is the center of the scattering source; the first plane mirror L1 has two planes, namely plane L1R1 and plane L1R2, and the reflection point of plane L1R1 and the reflection point of plane L1R2 can be regarded as the same point, that is, point P1. The second plane mirror L2 has two planes, namely plane L2R1 and plane L2R2, and the reflection point of plane L2R1 and the reflection point of plane L2R2 can be regarded as the same point, that is, point P2. OP1 or OP2 is the main optical axis, point A is the point where the first reflected light path intersects the first target 130, point B is the point where the second reflected light path intersects the first target 130, OP⊥AB, n1 is the normal to the plane L1R2 of the first plane mirror L1, n2 is the normal to the plane L2R2 of the second plane mirror L2, θ1 is the reflection angle of the plane L1R2 of the first plane mirror L1, θ2 is the reflection angle of the plane L2R2 of the second plane mirror L2; the first target 130 is vertical, and the incident light path is horizontal. Figure 2 The Y+ direction is the vertical upward direction, and the Y- direction is the vertical downward direction.
[0036] It can be understood that the angle between the first plane mirror L1 and the second plane mirror L2 can be obtained by the surface reflection angle of the first plane mirror L1 and the surface reflection angle of the second plane mirror L2. A right triangle is formed between AO, AP1, and OP1, and a right triangle is formed between BO, BP2, and OP2. According to the trigonometric function relationship of the right triangle, we can obtain:
[0037] AO=tan(2θ 1 )OP 1 ;
[0038] BO=tan(2θ 2 )OP 2 ;
[0039] AO and BO can characterize the angle between the first plane mirror L1 and the second plane mirror L2. Therefore, according to the preset angle range, the preset length range of AO and BO can be calculated first. When AO and BO both fall within the preset length range, it means that the angle between the first plane mirror L1 and the second plane mirror L2 meets the preset angle range. Therefore, the dry window inspection device of the present application can inspect whether the angle between the two plane mirrors of the dry window meets the preset angle range.
[0040] It should be noted that the present application does not make any specific limitation on the preset angle range, and those skilled in the art may set the preset angle range according to actual conditions.
[0041] It is understandable that the first target 130 is provided with a coordinate system. A preset length range is marked on the coordinate system. When performing an inspection, the light source module 120 is started to observe whether the point where the first reflected light path intersects with the first target 130 and the point where the second reflected light path intersects with the first target 130 fall within the preset length range, which is convenient and quick.
[0042] It can be understood that the emission light paths of the first target 130 and the light source module 120 are perpendicular to each other.
[0043] It is understandable that the present application further includes a second target 140, which is located on one side of the dry window mounting seat 110, and the dry window mounting seat 110 is located between the second target 140 and the light source module 120; the second target 140 is provided with an identification area, and the identification area is opposite to the emission end of the light source module 120. The second target 140 is used to verify whether the emission light path of the light source module 120 has changed. When the emission light path of the light source module 120 can pass through the identification area of the second target 140 every time, it means that there is no change in the light path.
[0044] Specifically, in some embodiments, referring to Figure 3 and Figure 4, the ideal position of point A and the ideal position of point B when the angle between the first plane mirror L1 and the second plane mirror L2 is the preset angle can be obtained according to the preset angle, and then the preset qualified range of point A and the preset qualified range of point B can be obtained according to the preset angle range. During the inspection process, if the point where the first reflected light path intersects with the first target 130 is within the qualified range of point A and the point where the second reflected light path intersects with the first target 130 is within the preset qualified range of point B, it indicates that the angle between the first plane mirror L1 and the second plane mirror L2 meets the preset angle range. Figure 3 It is a schematic diagram of the inspection in the absolute coordinate system. Figure 4 It is a schematic diagram of the inspection in the relative coordinate system. Figure 3 and Figure 4 Multiple groups of test data are included in the "actual point A" represents the point where the first reflected light path intersects with the first target 130 during the detection process; the "actual point B" represents the point where the second reflected light path intersects with the first target 130 during the detection process; the "actual point A-point B" represents the point where the first reflected light path intersects with the first target 130 and the point where the second reflected light path intersects with the first target 130 during the detection process.
[0045] It is understandable that a power module is also included, the power module is electrically connected to the light source module 120 , and the power module is used to supply power to the light source module 120 .
[0046] It is understandable that the base 100 is further included, and the dry window mounting base 110 , the light source module 120 , the first target 130 , and the second target 140 are all mounted on the base 100 .
[0047] It can be understood that the light source module 120 includes a laser tube.
[0048] It is understandable that the light source module 120 further includes a first support plate and a second support plate. The first support plate and the second support plate are spaced apart and arranged on the base 100 , and the laser tube is horizontally mounted on the first support plate and the second support plate.
[0049] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
