Referring to fig. 1 and 4, the sensing unit 30 includes a rotating member 31, a stage 32, a second power source and an image sensor 33, the rotating member 31 and the stage 32 are both hollow cylindrical, the rotating member 31 and the image sensor 33 are respectively located on two side end surfaces of the stage 32, the stage 32 is used for carrying the rotating member 31, the rotating member 31 has a through hole 311, the through hole 311 axially penetrates through the rotating member 31 and downwardly penetrates through the stage 32, the rotating member 31 carries the lens 90, the lens 90 and the image sensor 33 respectively cover openings at two ends of the through hole 311, and the second power source is, for example, a motor and a transmission mechanism thereof, so as to drive the rotating member 31 to rotate relative to the stage 32.
Referring to fig. 1 and fig. 2, the adjusting seat 40 has a pushing member 41 and a third power source, the supporting member 11 of the base 10 is disposed at one end of the pushing member 41, and the third power source is, for example, a motor and a transmission mechanism thereof, so as to drive the pushing member 41 to move along a first direction (in the embodiment, the Z direction), so as to push the supporting member 11 to move along the first direction relative to the base 10.
The box 50 is disposed above the base 10, and the box 50 has a receiving space for receiving the supporting unit 20 and the sensing unit 30, so that the box 50 can detect stray light in a dark environment, and prevent an incoherent light source from interfering with a detection result.
In the present invention, the light source 80 on the linkage element is used to irradiate a predetermined position on the surface of the lens 90, as shown in fig. 3, in this embodiment, the predetermined position of the lens refers to a central point on the upper surface of the lens, and the light emitted from the light source 80 penetrates through the lens 90 from the predetermined position of the lens 90 and then is received by the image sensor through the through hole 311.
Referring to fig. 1 and fig. 3, when it is required to observe whether stray light is generated in the lens under different incident angles, the shaft 21 can be driven to rotate by the first power source, and the rotation of the shaft 21 enables the linking member 22 to rotate around the central line of the shaft 21, so as to change the angle of the light source 80 irradiating the preset position of the lens 90, so as to observe the stray light of the lens 90 under different incident angles. Further, since the linking member 22 rotates along the axis, the light source 80 on the linking member 22 swings in an arc shape with the axis as the center, so that the light source 80 can maintain the preset position of the lens 90 when swinging as long as the light emitted by the light source 80 intersects the axis at the preset position of the lens 90, that is, as long as the axis of the rotation of the linking member 22 passes through the preset position of the lens 90 and the light emitted by the light source 80 passes through the preset position of the lens 90, when the linking member 22 drives the light source 80 to swing, the light emitted by the light source 80 can swing along an axial plane inside the lens 90 with the preset position of the lens 90 as the pivot, and the stray light condition of the axial plane of the lens 90 can be observed. The axial surface of the lens refers to a surface including the lens axis line inside the lens. In addition, the supporting member 23 can increase the stability of the linking member 22 during rotation, and prevent the linking member 22 from shaking during rotation.
As mentioned above, referring to fig. 4, after the light source 80 has been swung to irradiate an axial plane inside the lens 90, the second power source drives the rotating member 31 to rotate, so that the lens 90 rotates by an angle, and then the linking member rotates, so that the light source 80 can irradiate the preset position of the lens 90 from different incident angles, and therefore, the light emitted by the light source 80 can be swung to irradiate along another axial plane inside the lens 90 with the preset position of the lens 90 as a pivot, so as to observe the stray light situation of the other axial plane of the lens 90.
It should be noted that, because the light source 80 can irradiate the preset position of the lens 90 at different incident angles, and the rotating member 31 can rotate the lens 90 at different angles, along with the rotation of the lens 90 at different angles, the light emitted by the light source 80 can use the preset position of the lens 90 as a pivot and can swing along different axial planes inside the lens 90 for irradiation, therefore, the optical quality detection device of the lens of the present creation can use the preset position of the lens 90 as a pivot for radial irradiation inside the lens, so as to perform stray light detection for different incident angles and multiple axial planes of the lens 90.
Referring to fig. 5, since different lenses may have different sizes and thicknesses, when different lenses are replaced and inspected, the irradiation of the light source 80 may deviate from the preset position of the lens, and at this time, the pushing member 41 may be driven by the third power source of the adjusting seat 40 to move along the first direction, so as to drive the supporting member 11, the supporting unit 30 and the lens to move along the first direction, so as to adjust the distance between the lens and the light source 80, and maintain the light source 80 irradiating the preset position of the lens. In addition, because the lens optical quality detection device of the present invention has a processing unit (for example, a computer), the signal generated by the image sensor 33 can be output to the processing unit for analysis, when the processing unit analyzes and images, it is found that the irradiation of the light source 80 deviates from the preset position of the lens, the processing unit can adjust the position of the lens by controlling the lifting of the pushing member 41 of the adjusting seat 40, so that the light source 80 can irradiate the preset position of the lens, therefore, the lens optical quality detection device of the present invention can change the position of the lens by controlling the lifting of the adjusting seat 40 through the processing unit, thereby achieving the effect of automatic correction, improving the detection efficiency and maintaining the detection accuracy. However, in other possible embodiments of the present invention, the lifting device is disposed between the supporting unit and the base to change the position of the light irradiation for performing automatic calibration, which is not impossible.
Referring to fig. 6, the optical quality inspection apparatus for lens according to the second embodiment of the present invention is substantially the same as the first embodiment shown in fig. 1 to 5, but the base 10 has the receiving groove 12, and the first connection portion 221 of the linking member is a plate, so the second embodiment basically adopts the reference numerals of the first embodiment. The first connecting portion 221 of the second embodiment is inserted into the receiving cavity 12 and can rotate in the receiving cavity 12, and the second connecting portion 222 protrudes from the first connecting portion 221, so that when the shaft 21 rotates, the first connecting portion 221 can be driven to rotate synchronously, and further the light source 80 can be driven to swing, which has a similar using effect as the first embodiment. In the present embodiment, the first connecting portion is in a circular plate shape, and in other possible embodiments of the present invention, the first connecting portion may also be in a semicircular plate shape, a fan shape or other shapes.
In the above embodiments, the lens optical quality detection apparatus utilizes the adjustment seat to lift the lens to change the distance between the lens and the light source, and in other possible embodiments of the present disclosure, the lens optical quality detection apparatus may not have the adjustment seat, but instead the image sensor is provided with a fourth power source, for example, a motor and a transmission mechanism thereof, so that the fourth power source can drive the image sensor to lift, and the image sensor drives the carrier to lift together with the lens to change the distance between the lens and the light source, and has similar use effects as the above embodiments. In addition, in the case of the lens optical quality detection apparatus having the fourth power source, a fifth power source may be further installed on the stage, the fifth power source is, for example, a motor and a transmission mechanism thereof, so that the image sensor and the stage are driven by the two power sources to move up and down, and the lens moves up and down together with the stage, so that the lens and the image sensor can be moved independently or the distance between the lens and the image sensor can be adjusted.
In the above embodiments, the first connecting portion of the linking member extends radially from the shaft member, and in other possible embodiments of the present disclosure, the first connecting portion of the linking member may also extend from the shaft member to other directions, as long as the shaft member can drive the linking member to rotate, and the light source on the linking member can irradiate the predetermined position of the lens, which is not limited in this disclosure.
In other possible embodiments of the present disclosure, the sensing unit may not have a stage, and the lens and the image sensor are respectively located on the upper and lower end surfaces of the rotating member.
In the above embodiments, the lens optical quality detection apparatus has a box, and in other possible embodiments of the present disclosure, the lens optical quality detection apparatus may not have a box, so that the lens can be detected in a dark environment by placing the lens optical quality detection apparatus in a darkroom, and the use effect is similar to that of the above embodiments.
In other possible embodiments of the present disclosure, the adjusting seat may not have a third power source and may manually lift the pushing element, and the position of the lens may be adjusted to enable the light source to irradiate the predetermined position of the lens, thereby achieving a similar calibration effect as the above embodiments.
In summary, the present invention provides a lens optical quality detection device, wherein when a shaft rotates, a coupling member drives a light source to irradiate at a predetermined position of a lens at different incident angles, so that light emitted from the light source can swing along an axial plane inside the lens with the predetermined position of the lens as a pivot to detect the occurrence of stray light on the axial plane inside the lens, and further, a rotating member of the lens optical quality detection device can drive the lens to rotate at an angle to allow the light to swing along another axial plane inside the lens, so that the light can swing and irradiate on different axial planes inside the lens with different angles of rotation of the lens, and further the occurrence of stray light on different axial planes inside the lens can be detected, that is, the lens optical quality detection device can not only make the light source irradiate at the predetermined position of the lens, but also can perform stray light detection on different incident angles and multiple axial planes of the lens, the accuracy of stray light detection is improved, and the lens optical quality detection apparatus provided by the present invention can be used for detecting stray light of the lens, and also can be applied to detecting other optical qualities of the lens, such as focal plane, resolution, focal length, etc., however, the above embodiments only describe and explain the technical content of the present invention, and the patent scope of the present patent shall be subject to the following claims.
