Description

Technical Field

[0001] The utility model relates to the technical field of production and detection of optical spherical mirrors, in particular to a production curvature detection device for optical spherical mirrors. Background Art

[0002] Spherical mirrors are very common in daily life. The lenses of the myopia glasses or reading glasses we usually wear are made of spherical mirrors. Spherical mirrors are also used in many optical instruments such as microscopes. During the production process of spherical mirrors, the curvature of the spherical mirrors needs to be tested in order to determine some parameter indicators such as the reflectivity of the spherical mirrors. Therefore, corresponding detection devices will be used.

[0003] The existing technology has the following problems:

[0004] 1. In the prior art, the detection of the curvature of a spherical mirror usually requires observing the trajectory of a laser pen on a grid plate to determine the curvature. This process usually requires people to manually move the laser pen left and right to complete. Manual movement is not easy to control the speed. Moving too fast or too slow will affect the trajectory of the laser pen. In addition, this method wastes physical strength during a long detection process.

[0005] 2. The detection device in the prior art is not convenient for distinguishing defective products from genuine products after detection, especially when more than two operators use the equipment together, which may easily lead to confusion. Moreover, such detection equipment is generally expensive. If it is placed on a desktop and is not stable enough, it may fall and break due to external collision, causing economic losses. Utility Model Content

Through the marking mechanism, the surface of a spherical mirror with uneven curvature can be marked to ensure that defective products and genuine products are not confused, making it easier for people to distinguish them.

[0010] Preferably, the four corners of the bottom of the base are fixedly connected with supporting feet, the bottom of the supporting feet are bonded with anti-skid pads, and the surface of the anti-skid pads is provided with anti-skid patterns.

[0028] In this embodiment, the marking mechanism 8 includes a No. 2 cylinder 801, and the end of the No. 2 cylinder 801 is fixedly connected to a connecting plate 802. The surface of the connecting plate 802 is adhered with a marking stamp 803. Through the setting of the marking mechanism 8, the surface of the spherical mirror with uneven curvature can be marked to ensure that defective products and genuine products will not be confused, which is convenient for people to distinguish.

[0029] In this embodiment, the four corners of the bottom of the base 1 are fixedly connected with supporting feet 21, the bottom of the supporting feet 21 is bonded with anti-skid pads 17, and the surface of the anti-skid pads is provided with anti-skid grooves.

The suction cup 19 can be set to allow the base 1 to be adsorbed on the desktop, so the device is not easily affected by external forces and overturned.

[0031] In this embodiment, a card slot 10 is opened at the rear of the surface of the base 1, and an insert block 12 is fixedly connected to the bottom of the grid plate 9. Through the provided card slot 10 and insert block 12, the grid plate 9 and the base 1 can be movably connected, and disassembly and replacement are quick and convenient. Example 2

[0032] On the basis of the first embodiment, a preferred embodiment of the optical spherical mirror production curvature detection device provided by the utility model is as follows: Figures 1 to 5 As shown:

[0033] In this embodiment, a lighting lamp 20 is movably installed near the middle of the inner wall of the vertical connecting column 2. The number of the lighting lamps 20 is two groups and they are symmetrically arranged. Through the two groups of lighting lamps 20, the working area of ​​the equipment can be illuminated when the lighting conditions are not good, which is convenient for people to operate and detect.

[0034] In this embodiment, a magnetic plate is fixedly connected to the inner wall surface of the vertical connecting column 2, and the bottom connection of the lighting lamp 20 is designed with magnetic attraction.

[0035] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0036] In actual application, the spherical mirror is placed in the placement plate 15, and the No. 1 cylinder 6 pushes the slider 5. The slider 5 moves back and forth at a constant speed in the slide groove 4 through the pulley, and the ball 13 at the bottom of the outer rod 11 rolls back and forth on the spherical mirror. The spring 16 in the connecting tube 7 can make the outer rod 11 rise and fall when passing through the raised position of the spherical mirror. While marking, the curvature of the spherical mirror is judged by observing the marking trajectory of the laser pen 14 on the grid plate 9. If the curvature is unqualified, the spherical mirror is placed under the marking mechanism 8, and the No. 2 cylinder 801 pushes the connecting plate 802 to move downward. The marking stamp 803 on its surface will leave a mark on the defective product, which is convenient for people to distinguish. Due to the anti-slip pad 17 set at the bottom of the support foot 21 and the suction cup 19 at the bottom of the base 1, the equipment can be placed stably on the desktop and is not easily overturned by external force. When the lighting conditions are not good, turn on the lighting 20 to illuminate the base 1, providing good detection conditions for the inspectors.

[0037] In summary, with the help of the above-mentioned technical scheme of the utility model, the slider is set and moves back and forth at a constant speed in the slide groove through the pulley under the push of the No. 1 cylinder, so that the laser pen draws a uniform curved trajectory on the grid plate, thereby improving the use effect of the detection device. The marking mechanism can mark the surface of the spherical mirror with uneven curvature to ensure that defective products and genuine products are not confused, which is convenient for people to distinguish. The setting of the suction cup and anti-slip pad increases the placement stability of the equipment, making the equipment less likely to be overturned by external force, thereby solving the problem that the traditional detection device has poor use effect, lacks marking and differentiation function and has poor placement stability.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
