Description

Technical Field

[0001] This utility model relates to the field of optical lens quality inspection technology, and in particular to a quality inspection device for optical lens processing. Background Technology

[0002] Quality inspection equipment for optical lens processing includes a three-dimensional coordinate measuring machine (3D coordinate measuring machine). This machine precisely measures the three-dimensional coordinates of the workpiece to accurately detect key parameters such as the geometric dimensions and form and position tolerances of the optical lens. It has the following structure:

[0003] 1. Body: As the basic support structure of the equipment, it provides a stable installation platform for the entire measurement system;

[0004] 2. Frame: The main frame that supports the measuring mechanism, which expands the measuring range through cooperation with the machine body;

[0005] 3. Measuring mechanism: Includes core components such as probes and sensors, used to acquire surface coordinate data of optical lenses through direct or non-contact methods. Its resolution and response speed determine the efficiency and accuracy of quality inspection.

[0006] The frame moves in the Y direction on the machine body by sliding along the guide rails. Since the guide rails are located on the worktable of the machine body, there are inevitably cutting debris, dust and other debris in the optical lens processing site. At the same time, workpieces may accidentally fall or shift during loading and unloading. These debris or workpieces can easily enter the gaps in the guide rails of the worktable. When debris accumulates or workpieces get stuck, the movement of the frame is obstructed, and systematic errors will appear in the measurement data, resulting in distorted quality inspection results of optical lenses, and thus affecting the accuracy of optical lens quality inspection. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a quality inspection device for optical lens processing. It solves the problem of the machine frame sliding along guide rails on the machine body in the Y direction. Since these guide rails are located on the machine body's worktable, and due to the unavoidable presence of cutting debris, dust, and other impurities at the optical lens processing site, as well as the possibility of accidental drops or displacement of workpieces during loading and unloading, these debris or workpieces can easily enter the gaps in the guide rails of the worktable. When debris accumulates or workpieces become stuck, the movement of the machine frame is obstructed, resulting in systematic errors in the measurement data and distorted quality inspection results for the optical lenses, thus affecting the accuracy of the optical lens quality inspection.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An inspection device for optical lens processing includes a body and a frame. The frame is slidably connected to the surface of the body. The body has a first side plate and a second side plate at each end corresponding to the frame. Both ends of the frame are equipped with telescopic protective covers. Each telescopic protective cover has a fixing mechanism for assembling and disassembling the telescopic protective cover. Each fixing mechanism includes a screw, a nut, an opening, a fixing hole, and a fixing plate. The screw is located outside the frame. One end of the telescopic protective cover is slidably connected to the outside of the screw. The nut is threadedly connected to the outside of the screw and is used to restrict the movement of the telescopic protective cover. The opening is located outside the first side plate. The fixing hole is located at the other end of the telescopic protective cover. The fixing plate is engaged inside the opening and the fixing hole and is used to restrict the movement of the telescopic protective cover.

[0010] Preferably, each side plate has a threaded rod on one side corresponding to each fixed plate, and each threaded rod has a threaded block threadedly connected to its exterior. The end of the fixed plate is slidably connected to the exterior of the threaded rod.

[0011] Preferably, the second side plate has a positioning groove on one side corresponding to each fixed plate, and the end of the telescopic protective cover is engaged inside the positioning groove.

[0012] Preferably, each side plate has a mounting hole on one side corresponding to each threaded rod, and the threaded rod is slidably connected inside the mounting hole. Each side of the frame has a mounting groove on one side corresponding to each threaded rod, and the threaded rod is slidably connected inside the mounting groove.

[0013] A connecting plate is provided between side plate one and side plate two. The two ends of the connecting plate are fixedly installed on the outside of side plate one and side plate two respectively. A fixing groove is provided on the outside of the machine body. The end of the connecting plate is snapped into the inside of the fixing groove. A threaded hole is provided on the side of the machine body corresponding to the fixing groove. A bolt is threaded inside the threaded hole. A washer is slidably connected inside the fixing groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The telescopic protective cover uses screws and nuts to quickly fix and remove one end of the cover. Then, the cover is fixed from the other end by using a fixing plate with openings and fixing holes. When the frame moves on the machine body, the telescopic protective cover moves with the frame, shielding the guide rail of the frame to prevent debris from falling into the guide rail. This avoids the guide rail from being affected by impurities, thus preventing the quality inspection results of optical lenses from being distorted and ensuring the accuracy of optical lens quality inspection.

[0016] 2. When maintenance of the guide rail is required, rotate the nut to disengage it from the screw, and rotate the bolt to move it away from the washer. At this time, the clamping and fixing of the connecting piece by the washer is released. Then, pull side plate one and side plate two upward to move them away from the machine body. During this process, the connection between one end of the telescopic protective cover and the screw is released. At this time, the telescopic protective cover, side plate one, and side plate two are all disassembled. Therefore, side plate one, side plate two, telescopic protective cover, and fixing mechanism can be disassembled and assembled according to the working conditions, improving the flexibility of its use.

[0027] This application provides a quality inspection device for optical lens processing, which effectively solves the technical problem of the frame sliding along the guide rail on the machine body in the Y direction. Since the guide rail is located on the worktable of the machine body, there are inevitably cutting debris, dust and other debris in the optical lens processing site. At the same time, the workpiece may fall or shift accidentally during loading and unloading. These debris or workpieces can easily enter the gap of the guide rail on the worktable. When debris accumulates or the workpiece gets stuck, the movement of the frame is hindered, and the measurement data will have systematic errors, resulting in the distortion of the quality inspection results of the optical lens, and thus affecting the accuracy of the quality inspection of the optical lens.

[0028] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the technical solution in this embodiment effectively solves the problem of the frame sliding along the guide rail on the machine body in the Y direction. Since the guide rail is located on the machine body's worktable, and due to the unavoidable presence of cutting debris, dust, and other impurities at the optical lens processing site, as well as the possibility of accidental drops or displacement of workpieces during loading and unloading, these debris or workpieces can easily enter the gaps in the guide rail of the worktable. When debris accumulates or workpieces become stuck, the movement of the frame is obstructed, resulting in systematic errors in the measurement data, distorting the quality inspection results of the optical lenses, and consequently affecting the accuracy of the optical lens quality inspection. The overall approach is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a quality inspection device for optical lens processing, including a body 1 and a frame 2. The frame 2 is slidably connected to the surface of the body 1. The body 1 is provided with a first side plate 3 and a second side plate 4 at both ends corresponding to the frame 2. Telescopic protective covers 5 are provided at both ends of the frame 2. Each telescopic protective cover 5 is provided with a fixing mechanism for disassembling and assembling the telescopic protective cover 5. Each fixing mechanism includes a screw 6, a nut 7, an opening 8, a fixing hole 9, and a fixing plate 10. The screw 6 is located outside the frame 2. One end of the telescopic protective cover 5 is slidably connected to the outside of the screw 6. The nut 7 is threadedly connected to the outside of the screw 6 and is used to restrict the movement of the telescopic protective cover 5. The opening 8 is opened outside the first side plate 3. The fixing hole 9 is opened at the other end of the telescopic protective cover 5. The fixing plate 10 is engaged inside the opening 8 and the fixing hole 9 and is used to restrict the movement of the telescopic protective cover 5.

[0030] When the frame 2 moves on the body 1, the telescopic protective cover 5 moves with the frame 2, shielding the guide rail of the frame 2 to prevent dust, debris and other objects from falling into the guide rail and to avoid the guide rail from being affected by impurities. Through the cooperation of the screw 6 and the nut 7, one end of the telescopic protective cover 5 can be quickly fixed and disassembled. Then, through the cooperation of the fixing plate 10 with the opening 8 and the fixing hole 9, the telescopic protective cover 5 is fixed from the other end.

[0031] Each side plate 3 is provided with a threaded rod 11 on one side of each fixed plate 10. Each threaded rod 11 is threadedly connected to the outside of a threaded block 12. The end of the fixed plate 10 is slidably connected to the outside of the threaded rod 11. The connection of the threaded block 12 on the threaded rod 11 increases the stability of the connection between the fixed plate 10 and the opening 8 and the fixed hole 9.

[0032] The side plate 2 4 has a positioning groove 13 on one side corresponding to each fixing plate 10. The end of the telescopic protective cover 5 is engaged in the inside of the positioning groove 13, which facilitates quick positioning of the telescopic protective cover 5, so that the fixing plate 10 can enter the fixing hole 9 through the opening 8.

[0033] Each side plate 3 has a mounting hole 14 on one side corresponding to each threaded rod 11. The threaded rod 11 is slidably connected inside the mounting hole 14, which facilitates the replacement of the threaded rod 11.

[0034] The frame 2 has a mounting groove 15 on one side corresponding to each screw 6. The screw 6 is slidably connected inside the mounting groove 15, which facilitates the replacement of the screw 6.

[0035] A connecting plate 16 is provided between side plate 3 and side plate 4. The two ends of the connecting plate 16 are fixedly installed on the outside of side plate 3 and side plate 4 respectively. A fixing groove 17 is provided on the outside of the machine body 1. The end of the connecting plate 16 is snapped into the inside of the fixing groove 17. A threaded hole 18 is provided on the side of the machine body 1 corresponding to the fixing groove 17. The threaded hole 18 communicates with the inside of the fixing groove 17. A bolt 19 is threadedly connected inside the threaded hole 18. A washer 20 is slidably connected inside the fixing groove 17.

[0036] The connecting plate 16 connects side plate 3 and side plate 4 into a whole. Through the cooperation of bolts 19, fixing grooves 17 and gaskets 20, the side plate is fixedly connected to the machine body 1. At the same time, the gaskets 20 can increase the stability of the connection and prevent the side plate from loosening during use. When it is necessary to disassemble the side plate, simply turn the bolts 19 to release the pressure on the gaskets 20, and the side plate can be easily separated from the machine body 1, which is convenient for maintenance of the guide rail.

[0037] Working principle:

[0038] First, before the quality inspection equipment, such as the 3D coordinate measuring machine, starts working, the frame 2 of the 3D coordinate measuring machine will move in the Y direction, sliding one end of the telescopic protective cover 5 outside the screw 6, and then threading the nut 7 to the outside of the screw 6 to fix one end of the telescopic protective cover 5. At this time, the other end of the telescopic protective cover 5 is engaged inside the positioning groove 13. The fixing plate 10 is inserted into the fixing hole 9 through the opening 8 to fix the telescopic protective cover 5. At this time, one end of the fixing plate 10 slides outside the threaded rod 11, and then the threaded block 12 is threaded to the outside of the threaded rod 11 to restrict the movement of the fixing plate 10. At this time, the telescopic protective cover 5 is installed. When the frame 2 moves on the machine body 1, the frame 2 drives the telescopic protective covers 5 on both sides to move. The telescopic protective covers 5 cover the guide rail part of the frame 2 that is moving.

[0039] The second step is to rotate the nut 7 to disengage it from the screw 6, rotate the bolt 19 to move it away from the washer 20, and release the clamping and fixing of the connecting piece by the washer 20. Then, pull the side plate 3 and the side plate 4 upward to move them away from the machine body 1. During this process, the connection between one end of the telescopic protective cover 5 and the screw 6 is released. At this time, the telescopic protective cover 5, the side plate 3, and the side plate 4 are all disassembled.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
