Description

Technical Field

[0001] The present invention relates to the field of conical mirror detection, and in particular to a detection device and method for producing optical conical mirrors. Background Art

[0002] Conical mirrors are mainly used to change the propagation direction of light beams, focus or expand beams, etc. As important optical components, conical mirrors are often used in laser measurement, laser alignment and other instruments. The purpose of testing conical mirrors is to ensure that their optical performance meets the design requirements, such as focal length accuracy, aberration control, reflection or refraction efficiency, etc., so as to ensure that they can work normally in optical systems (such as laser processing equipment, optical imaging systems, etc.).

[0003] Chinese invention patent CN201210430288.7 discloses a semi-automatic conical mirror detection platform, including a rotating motor, a rotating shaft, a conical mirror seat, and a laser horizontal adjustment seat; the rotating motor drives the rotating shaft to rotate through the motor gear on its transmission shaft, the transmission belt, and the shaft gear at the top of the rotating shaft. The semi-automatic conical mirror detection platform has the advantages of simple and compact structure, stable and fast operation, high precision and high efficiency.

[0004] However, the above-mentioned semi-automatic conical mirror detection platform conical mirror has the axis of the mirror seat coincident with the axis of the exit pupil of the laser seat on the laser horizontal adjustment seat to ensure that the emitted laser hits the top of the conical mirror vertically to produce a uniform laser line, and then uses a linear array CCD probe to detect the laser line. It is more dependent on the CCD probe's laser line detection algorithm and the accuracy of the CCD probe, and the operation is relatively cumbersome and inconvenient to use. Summary of the invention

[0005] In view of this, the present invention provides a detection device and method for producing optical conical mirrors, and the main technical problem to be solved is to provide a more convenient detection device for producing optical conical mirrors.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a detection device for the production of optical conical mirrors, comprising a bracket, a driving mechanism is installed on the bracket, a photodiode sensor is installed at the bottom of the bracket, a conical mirror is installed inside the bracket, and the conical mirror is located above the photodiode sensor. The driving mechanism comprises a mounting frame, a first gear is movably connected inside the mounting frame, a connecting frame is fixedly connected to the inner surface of the first gear, an adjustment frame is fixedly connected to the bottom of the connecting frame, a moving block is movably connected inside the adjusting frame, a rotating column is movably connected to the bottom of the moving block, a rectangular spotlight is fixedly connected to the bottom of the rotating column, and the driving mechanism also comprises a motor, a rotating shaft is fixedly connected to the output end of the motor, a second gear is fixedly connected to the top of the rotating shaft, and the side of the second gear is meshingly connected to the side of the first gear.

[0007] By adopting the above technical solution, the rectangular spotlight will emit a long rectangular light strip, which will be irradiated on the conical mirror. The light refracted by the conical mirror will be irradiated on the photodiode sensor, thereby converting the change in light intensity into a change in current intensity. There are multiple photodiode sensors. Under normal conditions, the current inside the photodiode sensor remains stable. When there is a problem with the quality of the conical mirror being detected and the light cannot be refracted correctly, part of the light will be refracted to the photodiode sensors on both sides. The current in the middle photodiode sensor will decrease, and the current in the photodiode sensors on both sides will increase. The effect of detecting the quality of the conical mirror is achieved by detecting the current change inside the photodiode sensor.

[0016] By adopting the above technical solution, the light emitted by the rectangular spotlight illuminates the surface of the conical mirror, and after being refracted by the conical mirror, the light passes through the through hole and illuminates the photodiode sensor.

[0017] As a further description of the above technical solution:

[0018] A track is fixedly connected to the inner surface of the mounting frame, a groove is formed on the outer surface of the first gear, and the track is located inside the groove.

[0019] By adopting the above technical solution, the first gear can rotate inside the mounting frame through the track inside the mounting frame and the groove on the surface of the first gear.

[0020] As a further description of the above technical solution:

[0021] An adjustment cavity is provided inside the adjustment frame, a screw rod is movably connected inside the adjustment cavity, and the moving block is mounted on the outer surface of the screw rod.

[0022] By adopting the above technical solution, the moving block is threadedly connected to the outer surface of the screw rod, and rotating the screw rod can adjust the position of the moving block, thereby controlling the position of the rectangular spotlight, so that the light emitted by the rectangular spotlight can be refracted by the conical mirror and illuminate the photodiode sensor.

[0023] As a further description of the above technical solution:

[0024] A rotation groove is formed at the bottom of the moving block, and the rotation column is installed inside the rotation groove by means of screws.

[0025] By adopting the above technical solution, the angle of the rotating column is adjusted before use, and then the screws are tightened to fix the rotating column, so that the angle of the rectangular spotlight can be adjusted so that the light emitted by the rectangular spotlight can be refracted by the conical mirror and illuminate the photodiode sensor.

[0026] A method for detecting an optical conic mirror in production, using the above-mentioned detection device for detecting an optical conic mirror in production, comprises the following steps:

[0027] S1. Place the conical mirror to be detected in the base, and place the photodiode sensor under the base;

[0028] S2. Adjust the position and angle of the rectangular spotlight at the bottom of the rotating column so that the light emitted by the rectangular spotlight can be refracted by the conical mirror and illuminate the photodiode sensor;

[0030] S4. When the rectangular spotlight rotates, the current in the photodiode sensor is detected to determine whether the conical mirror meets the standards.

[0031] By adopting the above technical solution, the light refracted by the conical mirror can be converted into the current in the photodiode sensor to determine whether the quality of the conical mirror is qualified, which reduces the difficulty of conical mirror quality detection and facilitates the detection of conical mirrors during the production process.

The current inside the middle photodiode sensor will decrease, and the current in the photodiode sensors on both sides will increase. The effect of conical mirror quality detection is achieved by detecting the current change inside the photodiode sensor. Compared with the existing semi-automatic conical mirror detection platform conical mirror that needs to rely on the CCD probe for the laser line detection algorithm and the accuracy of the CCD probe, the optical conical mirror production detection device has a simple structure and is easy to operate, which is convenient for production detection of conical mirrors.
