Description

Technical Field

[0001] This utility model belongs to the field of optical measurement device technology, and in particular relates to an automatic identification optical comparison angle measuring instrument. Background Technology

[0002] An optical comparison goniometer is an optical measuring instrument that uses the principle of optical autocollimation to measure angular errors through comparison. It has a simple structure and is widely used. It is mainly suitable for measuring the optical parallelism difference of glass plates and various prisms, measuring the perpendicularity of two planes, or measuring the deviation of a prism angle from a standard angle using standard angle blocks. It can also be used to measure angular errors between various mounting surfaces.

[0003] When measuring large quantities of optical components, the human eye needs to be close to the eyepiece of the comparative goniometer, which puts great pressure on the eyes. At the same time, it is also necessary to constantly judge and record whether the wedge angle of the optical component is qualified, which makes the labor intensity of the human quite high.

[0004] Therefore, it is necessary to improve the existing optical comparison goniometer to increase detection efficiency and reduce the workload of inspectors. Utility Model Content

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An automatic identification optical comparison goniometer includes a bracket and a goniometer lens. The goniometer lens includes an objective lens and an eyepiece. One end of the eyepiece is equipped with a CCD camera lens and a main unit. One end of the CCD camera lens is electrically connected to the main unit, and the other end of the CCD camera lens is connected to the eyepiece via a connector. The connector includes two sets of locking rings of the same size, and an adjusting screw is provided between the two locking rings. The bottom of the bracket is equipped with a loading assembly, which includes a loading stage, an adjusting frame, and a lamp holder.

[0008] Furthermore, the diameter of the locking ring is larger than the diameter of the CCD camera lens and the eyepiece, and the two locking rings are respectively fitted onto the CCD camera lens and the eyepiece.

[0009] Furthermore, the locking ring is provided with two sets of symmetrical locking screws, the locking screws are threadedly connected to the locking ring, and one end of the locking screw extends into the locking ring.

[0010] Furthermore, the locking ring is provided with a connecting ring, and the adjusting screw passes through the connecting rings on the two locking rings respectively.

[0011] Furthermore, the loading assembly is located below the goniometer lens, the loading stage is connected to the bracket via an adjustment frame, and the lamp holder is located below the loading stage.

[0012] The beneficial effects of this utility model are:

[0013] 1) The image on the eyepiece reticle is captured by a CCD camera lens, and then the image data is transmitted to the host for recognition and processing, replacing traditional manual inspection and achieving automatic recognition and inspection. This improves inspection efficiency and reduces the intensity of manual inspection.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] See Figures 1-2 This utility model provides a technical solution:

[0020] like Figures 1-2As shown, an automatic identification optical comparison goniometer includes a bracket 2 and a goniometer lens 1. The goniometer lens 1 is detachably connected to the bracket 2 via an adjustment rod. The goniometer lens 1 includes an objective lens 12 and an eyepiece 11. A CCD camera lens 3 and a main unit (not shown in the figure) are disposed above the eyepiece 11. The tail of the CCD camera lens 3 is electrically connected to the main unit via a data cable. The identification end of the CCD camera lens 3 is connected to the eyepiece 11 via a connector 4.

[0021] A CCD camera is a digital camera with a charge-coupled device (CCD) image sensor. The CCD camera lens 3 is connected to the eyepiece 11. The CCD camera lens 3 captures images on the reticle of the eyepiece 11, and then transmits the image data to the host computer for recognition and processing, replacing traditional manual inspection and achieving automatic recognition and inspection. This improves inspection efficiency and reduces the intensity of manual inspection. At the same time, the connector 4 allows for quick connection between the CCD camera lens 3 and existing comparative goniometers, enabling rapid modification of comparative goniometers and improving the utilization of existing comparative goniometers.

[0022] Furthermore, the connector 4 includes two sets of locking rings 41 of the same size and specifications. The locking rings 41 are respectively fitted onto the CCD camera lens 3 and the eyepiece 11. The diameter of the locking rings 41 is larger than the diameter of the CCD camera lens 3 and the eyepiece 11, so that the two locking rings 41 can be quickly fitted onto the CCD camera lens 3 and the eyepiece 11 respectively.

[0023] Furthermore, the locking ring 41 is provided with two sets of symmetrical locking screws 42, the locking screws 42 are threadedly connected to the locking ring 41, and one end of the locking screw 42 extends into the locking ring 41.

[0024] By tightening the locking screw 42, the locking screw 42 is pressed against the eyepiece 11 or CCD camera lens 3 to complete the locking. At this time, the locking ring 41 will not fall off. At the same time, the locking screw 42 can be adapted to eyepieces 11 or CCD camera lenses 3 of different diameters, which improves the application scenarios of the connector 4 and allows for the modification and use of different models of comparative goniometers.

[0025] Furthermore, an adjusting screw 43 is provided between the two locking rings 41, and a connecting ring 44 is provided on the locking ring 41. The adjusting screw 43 passes through the connecting rings 44 on the two locking rings 41 respectively. A nut 45 is provided on the adjusting screw 43 near the connecting ring 44, and the outer diameter of the nut 45 is larger than the inner diameter of the connecting ring 44.

[0026] The two locking rings 41 are connected by an adjusting screw 43. Depending on the actual use, the distance between the two locking rings 41 can be adjusted by adjusting the screw 43, thereby adjusting the distance between the lens 11 and the CCD camera lens 3. Simultaneously, the nut 45, abutting against the connecting ring 44, provides support for the upper CCD camera lens 3 and the locking rings 41. Specifically... Figure 1 As shown, a nut 45 is located below the connecting ring 44 of the upper locking ring 41, and a nut 45 is located above the connecting ring 44 of the lower locking ring 41. Since the adjusting screw 43 and the connecting ring 44 are connected by an insertion joint, the upper locking ring 41 is supported on the upper nut 45 via the connecting ring 44, while the screw is supported on the lower connecting ring 44 via the lower nut 45. Therefore, by loosening the supporting nuts 45, the adjusting screw 43 can be adjusted, thereby adjusting the distance between the two locking rings 41.

[0027] Furthermore, the bottom of the support 2 is provided with a loading assembly 5, which includes a loading platform 51, an adjustment frame 53, and a lamp holder 52. The loading assembly 5 is located below the goniometer lens 1, the loading platform 51 is connected to the support 2 through the adjustment frame 53, and the lamp holder 52 is located below the loading platform 51.

[0028] Through the above technical solution, the platform 51 can be arranged by the loading component 5, and supplementary lighting can be provided by the lamp holder 52.

[0029] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
