Description

Technical Field

[0001] This utility model relates to the field of point accuracy detection, and in particular to a point accuracy detection device. Background Technology

[0002] Collimators can transform divergent beams emitted from the end face of an optical fiber into parallel beams, or converge parallel beams and efficiently couple them into the optical fiber, and are widely used in optical communication systems.

[0003] During the production process of a collimator, it is often necessary to test the point accuracy of the collimator.

[0004] The existing point accuracy testing device includes a light source emitter and a point accuracy measuring plate; the point accuracy measuring plate is engraved with a point accuracy measuring target ring; during testing, a collimator is installed on the emitting end of the light source emitter so that the light beam emitted by the light source emitter shines on the point accuracy measuring plate after passing through the collimator, and then the point accuracy is measured by the point accuracy measuring target ring.

[0005] When measuring point accuracy, the distance between the light source emitter and the point accuracy measuring board needs to be adjusted. Only a suitable distance can ensure accurate point accuracy measurement. Currently, both the light source emitter and the point accuracy measuring board are fixed to the base with bolts. Every time the distance between the light source emitter and the point accuracy measuring board needs to be adjusted, the point accuracy measuring board needs to be disassembled, adjusted, and then fixed back in place, which is a very cumbersome operation.

[0006] Therefore, it is particularly necessary to design a point accuracy detection device that allows for easy adjustment of the distance between the light source emitter and the point accuracy measurement plate. Utility Model Content

[0007] The purpose of this invention is to provide a point accuracy detection device that addresses the aforementioned problems, allowing for convenient adjustment of the distance between the light source emitter and the point accuracy measuring plate.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A point accuracy detection device includes a base, a light source emitter, a fixed base, a point accuracy measuring plate, a movable base, and a driving device. The movable base is slidably disposed on the top of the base, and the point accuracy measuring plate is fixedly disposed on the top of the movable base. A point accuracy measuring target ring is engraved on the point accuracy measuring plate. The fixed base is fixedly disposed on the top of the base, and the light source emitter is fixedly disposed on the top of the fixed base. The emitting end of the light source emitter faces the point accuracy measuring plate, and the central axis of the emitting end of the light source emitter passes through the center point of the point accuracy measuring target ring. The driving device is disposed on the base and is used to drive the movable base to move on the base, so that the point accuracy measuring plate moves closer to or further away from the emitting end of the light source emitter.

[0010] Furthermore, the driving device is a lead screw mechanism, which includes a first support, a second support, and a lead screw. The first and second supports are located on both sides of the movable seat and are fixedly mounted on the top of the base. One end of the lead screw is rotatably mounted on the first support and the other end is rotatably mounted on the second support. The lead screw is parallel to the central axis of the emitting end of the light source emitter. The movable seat is threaded onto the lead screw. When the lead screw rotates, the movable seat moves along the lead screw, moving closer to or away from the emitting end of the light source emitter.

[0011] Furthermore, a rotating handle is connected to the end of the lead screw away from the light source emitter.

[0012] Furthermore, a drive motor is connected to the end of the lead screw away from the light source emitter, and the drive motor is fixedly mounted on the top of the base; a distance detection sensor is provided on the top of the light source emitter, and the distance detection sensor is used to detect the distance from the point precision measuring plate to the emitting end of the light source emitter; both the drive motor and the distance detection sensor are connected to the controller, and the controller is also connected to control buttons and a display.

[0013] Furthermore, a camera is fixedly installed next to the light source emitter, with the camera's viewing angle aimed at the emitting end of the light source emitter, and the camera is connected to the controller.

[0014] Furthermore, the camera is fixedly mounted next to the light source emitter via a pole; the camera is fixedly mounted at the upper end of the pole, and the lower end of the pole is fixedly mounted on the top of the base.

[0015] Furthermore, a supplementary light is also provided at the upper end of the pole, and the supplementary light is connected to the controller.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, since the movable seat is slidably mounted on the base, the position of the movable seat on the base can be easily adjusted by the driving device, thereby facilitating the adjustment of the distance between the light source emitter and the point precision measuring plate.

[0028] like Figures 1-3 As shown, this utility model discloses a point accuracy detection device, which includes a base 1, a light source emitter 3, a fixed base 2, a point accuracy measuring plate 5, a movable base 9, and a driving device. The movable base 9 is slidably disposed on the top of the base 1, and the point accuracy measuring plate 5 is fixedly disposed on the top of the movable base 9. A point accuracy measuring target ring is engraved on the point accuracy measuring plate 5. The fixed base 2 is fixedly disposed on the top of the base 1, and the light source emitter 3 is fixedly disposed on the top of the fixed base 2. The emitting end of the light source emitter 3 faces the point accuracy measuring plate 5, and the central axis of the emitting end of the light source emitter 3 passes through the center point of the point accuracy measuring target ring. The driving device is disposed on the base 1, and the driving device is used to drive the movable base 9 to move on the base 1, so that the point accuracy measuring plate 5 moves closer to or away from the emitting end of the light source emitter 3.

[0029] Since the movable seat 9 is slidably mounted on the base 1, the position of the movable seat 9 on the base 1 can be easily adjusted by the drive device, thereby facilitating the adjustment of the distance between the light source emitter 3 and the point accuracy measuring plate 5.

[0030] Furthermore, the driving device is a lead screw mechanism, which includes a first support 7, a second support 10, and a lead screw 8. The first support 7 and the second support 10 are located on both sides of the movable seat 9 and are fixedly mounted on the top of the base 1. One end of the lead screw 8 is rotatably mounted on the first support 7, and the other end is rotatably mounted on the second support 10. The lead screw 8 is parallel to the central axis of the emitting end of the light source emitter 3. The movable seat 9 is threadedly mounted on the lead screw 8. When the lead screw 8 rotates, the movable seat 9 moves along the lead screw 8, moving closer to or away from the emitting end of the light source emitter 3.

[0031] The driving device of this utility model is a lead screw mechanism. The position of the movable seat 9 on the base 1 can be easily adjusted through the lead screw mechanism, thereby facilitating the adjustment of the distance between the light source emitter 3 and the point accuracy measuring plate 5. At the same time, the lead screw 8 has a self-locking characteristic, which can prevent the point accuracy measuring plate 5 from sliding during operation.

[0032] The lead screw 8 of this invention can be rotated manually or driven by the drive motor 6; when rotated manually, the end of the lead screw 8 away from the light source emitter 3 is connected to a rotating handle.

[0033] When driven by the drive motor 6, the end of the lead screw 8 furthest from the light source emitter 3 is connected to the drive motor 6, which is fixedly mounted on the top of the base 1. A distance detection sensor 4 is mounted on the top of the light source emitter 3, and the distance detection sensor 4 is used to detect the distance from the point precision measuring plate 5 to the emitting end of the light source emitter 3. Both the drive motor 6 and the distance detection sensor 4 are connected to a controller, which is also connected to control buttons and a display. The controller, distance detection sensor 4, drive motor 6, control buttons, and display are all connected to a power source.

[0034] Due to the above structure, the drive motor 6 can be rotated by the control button, which in turn controls the lead screw 8 to rotate, thereby adjusting the distance between the light source emitter 3 and the point accuracy measuring plate 5. The display can then directly show the distance between the light source emitter 3 and the point accuracy measuring plate 5.

[0035] Furthermore, a camera 13 is fixedly installed next to the light source emitter 3. The camera 13 is positioned with its viewing angle directed at the emitting end of the light source emitter 3. The camera 13 is connected to the controller and the power supply.

[0036] When testing the point accuracy of different types of collimators, the distance between the light source emitter 3 and the point accuracy measuring plate 5 needs to be adjusted. Due to the presence of the camera 13, the camera 13 can quickly obtain the type of collimator through image information. Then, the controller can automatically control the drive motor 6 to rotate based on the image information obtained by the camera 13, thereby automatically adjusting the point accuracy measuring plate 5 to the appropriate position, greatly improving work efficiency.

[0037] Furthermore, the camera 13 is fixedly mounted next to the light source emitter 3 via a pole 11; the camera 13 is fixedly mounted at the upper end of the pole 11, and the lower end of the pole 11 is fixedly mounted at the top of the base 1.

[0038] Furthermore, a supplementary light 12 is also provided at the upper end of the pole 11, and the supplementary light 12 is connected to the controller and the power supply. Due to the presence of the supplementary light 12, the camera 13 can acquire image information more clearly.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
