Description

Technical Field

[0001] The present invention relates to the field of holographic scanning, and particularly to a scanning and detecting device for digital holographic microscopy imaging of ceramic handicrafts. Background Art

[0002] The scanning and detecting device for digital holographic microscopy imaging of ceramic handicrafts is a high-tech device specially used for detecting the surface topography and structure of ceramic handicrafts. It combines digital holography technology and microscopy imaging technology, and can achieve high-precision and non-contact three-dimensional scanning and detection of ceramic handicrafts.

[0003] After retrieval, a Chinese patent with the publication number CN110879045A discloses a scanning and detecting device for digital holographic microscopy imaging of ceramic handicrafts, including a workbench. A mounting frame is fixedly connected to the top end of the workbench. A mounting slot is opened in the middle of the top end of the mounting frame. A support seat is fixedly connected to the top end of the workbench corresponding to the inner side of the mounting frame. A lifting mechanism is rotatably connected to the inner side of the support seat. The lifting mechanism includes a rotating shaft, a rotating disk, a wire winding roller, a traction steel cable, a connecting buckle, an annular frame and a sliding slot. Through the cooperation of the rotating shaft, the rotating disk and the wire winding roller, the winding and unwinding of the traction steel cable are controlled. Through the cooperation of the traction steel cable and the connecting buckle, the rotation of the annular frame is controlled, so as to adjust the height of the three-dimensional scanner inside the annular frame. At the same time, due to the annular structure of the annular frame, the three-dimensional scanner always faces the ceramic handicraft directly and keeps the distance unchanged when changing the height, improving the accuracy of the scanning data of the three-dimensional scanner and reducing the workload of the later repair of the three-dimensional model. However, when the above solution is actually used, there are still the following deficiencies: The scanning device proposed by the above solution is suitable for small ceramic handicrafts. For large ceramic handicrafts such as large ceramic jars, on the one hand, the size of the annular frame limits the placement space of the large ceramic handicrafts, making it difficult for large works to adapt and be effectively detected. On the other hand, the staff needs to laboriously place the large ceramic handicrafts on the rotating disk by lifting, which not only increases the operation difficulty, but also may cause damage to the handicrafts or increase the safety risk of the staff.

[0004] Therefore, it is necessary to design a scanning and detecting device for digital holographic microscopy imaging of ceramic handicrafts to solve the above problems. Summary of the Invention

[0016] Advantages of the present invention: 1. By setting up a guide rail assembly and a traction unit, the device realizes the automated movement of large ceramic crafts. The staff only needs to adjust the position of the traction device to easily pull the storage table from the ground to the rack. When the storage table is accurately moved to the top of the drive block, the drive seat can be smoothly engaged with the drive block by rotating the threaded sleeve, thereby enabling the driver to drive the storage table to rotate, providing convenience for holographic inspection of ceramic crafts. This design not only greatly reduces the workload of staff and avoids heavy manual handling work, but also effectively prevents possible damage to ceramic crafts during the lifting process, ensuring the safety and integrity of ceramic crafts. 2. Through the design of the clamping unit, the staff can efficiently fix the ceramic crafts on the storage table. The operation process is simple and convenient. Just pull up the positioning ring to disengage the positioning rod from the positioning groove, and then you can freely rotate the cross plate and drive the supercharger and the clamping plate to adjust their positions. At the same time, lift the clamping plate to retract the rod into the cylinder, providing space for the clamping plate to rotate directly above the ceramic craft. When the positioning groove is aligned with the positioning rod, loosen the positioning ring to reinsert the positioning rod into the positioning groove to fix the position of the cross plate. Then, loosen the clamping plate. Under the elastic force of the connecting spring, the clamping plate automatically moves down and tightly presses the top of the ceramic craft to achieve a firm fixation. This design not only improves the flexibility and accuracy of the fixing operation, but also ensures the stability and safety of the ceramic crafts during the inspection process, effectively preventing damage caused by movement or vibration. 3. When the traction unit pulls the storage table upward, the ceramic craft will lift the compression plate, causing the rod to retract into the cylinder. This dynamic adjustment ensures that the compression plate always maintains close contact with the ceramic craft. During the horizontal movement, the ceramic craft drives the booster and guide seat to move through the compression plate. This linkage mechanism enables the compression plate to continuously apply a stable compression force to the ceramic craft. This design not only effectively prevents the ceramic craft from shaking or tipping over during movement, but also greatly improves the safety and stability of the ceramic craft during the traction process.

Specific embodiments

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0021] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, rather than physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product.

[0022] The present invention provides a technical solution. Referring to Figures 1 to 14 as shown, a scanning and detecting device for a digital holographic microscopy imaging device of a ceramic handicraft includes a holographic scanning device, a connecting component, a guide rail 31 component, a traction unit and a pressing unit. The holographic scanning device includes a frame 101, a rotator 102, a driving block 1021, a placing table 103, a driving module 105 and a microscopic photographing module 106. The rotator 102 is installed on the frame 101, the driving block 1021 is fixed on the rotating part of the rotator 102, the placing table 103 is arranged above the rotator 102 and is connected to the driving block 1021. An installation bracket 104 is fixed on the frame 101, and both the driving module 105 and the microscopic photographing module 106 are installed on the installation bracket 104. Two slots 26 are formed on the placing table 103. When dealing with small ceramic handicrafts, the staff directly places the ceramic handicraft on the placing table 103. When performing scanning processing, the staff starts the driving module 105, the microscopic photographing module 106 and the driver. When the driver operates, it drives the driving block 1021 to rotate. The cross-sections of both the driving block 1021 and the driving groove 27 are rectangular structures. Therefore, the driving block 1021 can drive the driving seat 23 to rotate, and the placing table 103 rotates accordingly. When the placing table 103 rotates, the ceramic handicraft on it rotates slowly. During this process, the microscopic photographing module 106 performs holographic microscopic photographing on the ceramic handicraft to obtain a three-dimensional model of the ceramic handicraft. During the photographing process, the driving module 105 is used to adjust the position of the microscopic photographing module 106 so that the microscopic photographing module 106 can comprehensively photograph the ceramic handicraft. It should be noted that the specific structures and working principles of the driving module 105, the microscopic photographing module 106 and the driver are prior art, and the implementation methods adopt conventional means, which are not shown in the figure and will not be elaborated here; Referring to Figure 4As shown in the figure, the connecting component is arranged on the bottom surface of the storage table 103 and is used to connect the storage table 103 and the driving block 1021. The connecting component includes a threaded rod 21, a threaded sleeve 22, a driving seat 23 and two limiting members. The threaded rod 21 is fixed at the center position of the bottom surface of the storage table 103. The threaded sleeve 22 is threadedly sleeved on the threaded rod 21. The driving seat 23 is rotatably assembled at the bottom end of the threaded sleeve 22. A driving groove 27 is formed on the bottom surface of the driving seat 23. The driving seat 23 is connected to the storage table 103 through two limiting members. The limiting member includes an outer cylinder 24 and an inner rod 25. The outer cylinder 24 is fixed on the side surface of the driving seat 23. The inner rod 25 is slidably arranged in the outer cylinder 24. The top end of the inner rod 25 extends to the outside of the outer cylinder 24 and is fixedly connected to the storage table 103. The inner surface of the outer cylinder 24 and the outer surface of the inner rod 25 are in mutual contact. The cross sections of the driving groove 27 and the driving block 1021 are both rectangular structures. When the driving block 1021 is inserted into the driving groove 27, the side surface of the driving block 1021 is in mutual contact with the groove wall of the driving groove 27. The staff rotates the threaded sleeve 22 to make the threaded sleeve 22 move upward along the threaded rod 21. When the threaded sleeve 22 moves upward, it can drive the driving seat 23 to move upward until the driving seat 23 is separated from the driving block 1021. During the movement of the driving seat 23, the two outer cylinders 24 and the two inner rods 25 jointly provide limit for the driving seat 23 to ensure the stability of the driving seat 23 during the movement; Refer to Figure 1 and Figure 2 As shown in the figure, the guide rail 31 component is arranged on the frame 101. The guide rail 31 component includes two guide rails 31. The guide rail 31 is in an L-shaped structure and has a horizontal part and a vertical part. The guide rail 31 component also includes two sliding seats 32, two inserting blocks 33, a linear driver 34 and two connecting rods 36. The two sliding seats 32 are respectively slidably assembled on the two guide rails 31. The two inserting blocks 33 are respectively fixed on the side surfaces of the two sliding seats 32. The linear driver 34 is installed on the frame 101. Two moving seats 35 are installed on the linear driver 34., One ends of the two connecting rods 36 are respectively connected to the two moving seats 35, and the other ends are respectively connected to the two guide rails 31. The staff first drives the linear driver 34 to make the linear driver 34 drive the two moving seats 35 to approach each other. When the moving seats 35 move, they can drive the guide rails 31 to move through the connecting rods 36, which makes the two guide rails 31 approach each other. During this process, the two sliding seats 32 and the two inserting blocks 33 will also approach each other until the two inserting blocks 33 are respectively inserted into the two slots 26 on the storage table 103. In this case, the two inserting blocks 33 and the two slots 26 can drive the storage table 103 to move. It should be noted that the linear driver 34 can drive the two moving seats 35 to approach or move away synchronously. The specific structure and working principle of the linear driver 34 are prior art, and the implementation method adopts conventional means, which are not shown in the figure and will not be elaborated here; Refer to Figures 5 to 10As shown, the traction unit is arranged on one of the guide rails 31. The traction unit includes a traction assembly, a clamping assembly, and a first positioning assembly. The traction assembly includes a fixed shaft 41, a rotating plate 42, and a traction device 43. The fixed shaft 41 is fixed at the intersection of the horizontal part and the vertical part of the guide rail 31. The rotating plate 42 is rotatably assembled on the fixed shaft 41. The traction device 43 is installed at one end of the rotating plate 42 away from the fixed shaft 41. The traction end of the traction device 43 is connected to the slide block 32 on the guide rail 31. The clamping assembly includes a fixing plate 52, a chute 53, a clamping block 54, and a convex block 56. The fixing plate 52 is fixed on the side surface of the rotating plate 42. The chute 53 is opened on the side surface of the fixing plate 52. The clamping block 54 is slidably arranged in the chute 53, and one end of the clamping block 54 extends to the outside of the chute 53. The clamping block 54 and the chute 53 are connected by a first spring 55. The convex block 56 is fixed at one end of the clamping block 54 located outside the chute 53. The cross-sections of the chute 53 and the clamping block 54 are both T-shaped structures. The first positioning assembly includes a fixed disk 51, two card slots 57, and two support blocks 58. The fixed disk 51 is fixedly sleeved on the fixed shaft 41. The two card slots 57 are both opened on the side surface of the fixed disk 51. The two support blocks 58 are both fixed on the side surface of the fixed disk 51. The staff starts the traction device 43 to make the traction device 43 pull the corresponding slide block 32, so that the two slide blocks 32 drive the placing table 103 to move upward through the two clamping blocks 54 and the two card slots 57. When the two slide blocks 32 move to the intersection of the vertical part and the horizontal part of the guide rail 31, the staff turns off the traction device 43 and pulls the convex block 56 again to move the clamping block 54 out of the corresponding card slot 57. Then the staff controls the rotating plate 42 to reverse until the rotating plate 42 rotates to the horizontal position again. When the rotating plate 42 rotates to the horizontal state, the clamping block 54 will face the card slot 57 again and snap into the card slot 57, so that the position of the rotating plate 42 is fixed again. In this case, the traction device 43 can apply a horizontal pulling force to the placing table 103. The staff starts the traction device 43 to make the traction device 43 pull the placing table 103 to move horizontally until the placing table 103 moves to directly above the driving block 1021. Based on the above process, the staff can adjust the position of the traction device 43 to make the traction device 43 pull the placing table 103 from the ground to the rack 101; Refer to Figures 11 to 14As shown in the figure, the pressing unit is arranged on the mounting frame 104. The pressing unit includes a pressing assembly and a second positioning assembly. The pressing assembly includes a fixed frame 61, a shaft rod 62, a cross plate 63, a boosting member 66 and a pressing plate 67. The fixed frame 61 is fixed on the mounting frame 104. The shaft rod 62 is fixed on the top surface of the fixed frame 61. The cross plate 63 is rotatably mounted on the shaft rod 62. A guide rail 64 is fixed on the bottom surface of the cross plate 63. A guide seat 65 is slidably arranged on the guide rail 64. The boosting member 66 is fixed on the guide seat 65. The pressing plate 67 is connected to the boosting member 66. The boosting member 66 includes a cylinder body and a rod body. The cylinder body is fixed on the guide seat 65. The rod body is slidably arranged in the cylinder body. The bottom end of the rod body extends to the outside of the cylinder body and is rotatably connected to the pressing plate 67. The cylinder body and the rod body are connected by a connecting spring. The second positioning assembly includes a fixing ring 71, two positioning grooves 72, a positioning ring 73, a positioning rod 74 and an end cap 75. The fixing ring 71 is fixed on the top surface of the cross plate 63. The two positioning grooves 72 are both formed in the fixing ring 71. The positioning ring 73 is slidably sleeved on the shaft rod 62 and is located above the fixing ring 71. The positioning rod 74 is fixed on the positioning ring 73 and is arranged opposite to one of the positioning grooves 72. The end cap 75 is fixed on the top end of the shaft rod 62. The positioning ring 73 and the end cap 75 are connected by a second spring 76. When the traction unit pulls the placing table 103 to move upward, the ceramic handicraft will lift the pressing plate 67, causing the pressing plate 67 to drive the rod body to move, and then the rod body to retract into the cylinder body. When the traction unit pulls the placing table 103 to move horizontally, the ceramic handicraft will drive the boosting member 66 to move through the pressing plate 67, and the boosting member 66 will drive the guide seat 65 to move. This design can ensure that the pressing plate 67 can always provide a pressing effect on the ceramic handicraft during the movement of the ceramic handicraft, so as to ensure the stability of the ceramic handicraft during the movement and avoid the situation of shaking or tipping of the ceramic handicraft when being towed.

[0023] The working principle of the present invention: When the scanning and detecting device of the digital holographic microscopy imaging device for ceramic handicrafts proposed by the present invention is in use, when dealing with small ceramic handicrafts, the staff directly place the ceramic handicrafts on the placing table 103. When performing scanning processing, the staff start the driving module 105, the microscopic photographing module 106 and the driver. When the driver operates, it drives the driving block 1021 to rotate. The cross-sections of the driving block 1021 and the driving groove 27 are both rectangular structures. Therefore, the driving block 1021 can drive the driving seat 23 to rotate, and the placing table 103 rotates accordingly. When the placing table 103 rotates, the ceramic handicrafts on it rotate slowly. During this process, the microscopic photographing module 106 performs holographic microscopic photographing on the ceramic handicrafts to obtain a three-dimensional model of the ceramic handicrafts. During the photographing process, the driving module 105 is used to adjust the position of the microscopic photographing module 106 so that the microscopic photographing module 106 can photograph the ceramic handicrafts comprehensively. It should be noted that the specific structures and working principles of the driving module 105, the microscopic photographing module 106 and the driver are prior arts, and the implementation methods adopt conventional means, which are not shown in the figure and will not be elaborated here; When it is necessary to detect large ceramic handicrafts, such as large ceramic jars, the staff first drive the linear driver 34 to make the linear driver 34 drive the two moving seats 35 to approach each other. When the moving seats 35 move, they can drive the guide rails 31 to move through the connecting rods 36, which makes the two guide rails 31 approach each other. During this process, the two sliding seats 32 and the two inserting blocks 33 will also approach each other until the two inserting blocks 33 are respectively inserted into the two slots 26 on the placing table 103. Further, the staff rotate the threaded sleeve 22 to make the threaded sleeve 22 move upward along the threaded rod 21. When the threaded sleeve 22 moves upward, it can drive the driving seat 23 to move upward until the driving seat 23 is separated from the driving block 1021. During the movement of the driving seat 23, the two outer cylinders 24 and the two inner rods 25 jointly provide limits for the driving seat 23 to ensure the stability of the driving seat 23 during the movement; When the driving seat 23 is separated from the driving block 1021, the staff manually move the placing table 103 to make the placing table 103 move along the two guide rails 31 until the two sliding seats 32 respectively move to the bottom positions of the vertical parts of the two guide rails 31. At this time, the placing table 103 can fall to the ground. In this case, the staff can lift the large ceramic handicraft onto the placing table 103. Since the placing table 103 has fallen to the ground, the staff do not need to lift the ceramic handicraft onto the frame 101, which is not only convenient to operate but also can avoid damage to the ceramic handicraft during the lifting process; After the ceramic handicraft is carried onto the placement table 103, the staff uses the pressing unit to press the top of the ceramic handicraft to provide a fixing effect on the ceramic handicraft. For the pressing unit, the staff first pulls up the positioning ring 73. When the positioning ring 73 moves, it drives the positioning rod 74 to move until the positioning rod 74 disengages from the corresponding positioning groove 72. Without the limiting effect of the positioning rod 74, the fixing ring 71 and the cross plate 63 can rotate freely. At this time, the staff rotates the cross plate 63, and when the cross plate 63 rotates, it can drive the pressure increasing member 66 and the pressing plate 67 to rotate. At the same time, the staff lifts the pressing plate 67 upward. When the pressing plate 67 moves upward, it can drive the rod body to move upward until the rod body retracts into the cylinder. When the pressing plate 67 rotates to directly above the ceramic handicraft, the staff stops rotating the cross plate 63. At this time, another positioning groove 72 is exactly opposite the positioning rod 74. In this case, the staff releases the positioning ring 73, so that the positioning ring 73 moves downward under the action of the second spring 76. When the positioning ring 73 moves downward, the positioning rod 74 will insert into the corresponding positioning groove 72 again to provide a limit for the cross plate 63. Further, the staff releases the pressing plate 67, so that the pressing plate 67 and the rod body move downward under the elastic force of the connecting spring until the pressing plate 67 presses the top of the ceramic handicraft. Under the pressing action of the pressing plate 67, the ceramic handicraft will be fixed on the placement table 103; After fixing the ceramic handicraft, the staff uses the traction unit to traction the ceramic handicraft until the placing table 103 moves above the driver. Specifically, the staff first pulls the bump 56, causing the bump 56 to drive the latch 54 to move until the latch 54 disengages from the corresponding card slot 57. Without the restriction of the latch 54, the rotating plate 42 can rotate. At this time, the staff can pull the handle on the rotating plate 42 to rotate the rotating plate 42 and the traction device 43 until the rotating plate 42 rotates to the vertical state. In this case, the latch 54 just rotates to a position facing another card slot 57, and the latch 54 will be snapped into the card slot 57 under the elastic force of the first spring 55. At this time, the latch 54 will provide a limit to the position of the rotating plate 42 to ensure the stability of the position of the rotating plate 42. In this case, the traction device 43 faces the vertical part of the guide rail 31, so as to facilitate the traction device 43 to apply an upward vertical pulling force to the sliding seat 32 on the guide rail 31. Further, the staff starts the traction device 43 to make the traction device 43 pull the corresponding sliding seat 32, so that the two sliding seats 32 drive the placing table 103 to move upward through the two latches 54 and the two card slots 57. When the two sliding seats 32 move to the intersection of the vertical part and the horizontal part of the guide rail 31, the staff turns off the traction device 43 and pulls the bump 56 again to move the latch 54 out of the corresponding card slot 57. Then the staff controls the rotating plate 42 to reverse until the rotating plate 42 rotates to the horizontal position again. When the rotating plate 42 rotates to the horizontal state, the latch 54 will face the card slot 57 again and snap into the card slot 57, making the position of the rotating plate 42 fixed again. In this case, the traction device 43 can apply a horizontal pulling force to the placing table 103. The staff starts the traction device 43 to make the traction device 43 pull the placing table 103 to move horizontally until the placing table 103 moves directly above the driving block 1021. Based on the above process, the staff can adjust the position of the traction device 43 to pull the placing table 103 from the ground to the frame 101 by the traction device 43; When the placing table 103 moves directly above the driving block 1021, the staff rotates the threaded sleeve 22, causing the threaded sleeve 22 to drive the driving seat 23 to move downward until the driving seat 23 is snapped onto the driving block 1021. In this case, the driver can drive the placing table 103 to rotate through the driving block 1021 and the driving seat 23, so as to facilitate the holographic detection of the ceramic handicraft. By setting the guide rail 31 assembly and the traction unit, the device can automatically move the large ceramic handicraft to the frame 101 without manually lifting the ceramic handicraft to the frame 101, which not only reduces the labor intensity of the staff, but also can avoid the situation of damage to the ceramic handicraft during the lifting process; It should be noted that when the traction unit pulls the placement table 103 upward, the ceramic handicraft will jack up the pressing plate 67, causing the pressing plate 67 to drive the rod body to move, and then the rod body will retract into the cylinder body. When the traction unit pulls the placement table 103 to move horizontally, the ceramic handicraft will drive the pressurizing member 66 to move through the pressing plate 67, and the pressurizing member 66 will drive the guide seat 65 to move. This design can ensure that the pressing plate 67 can always provide a pressing effect on the ceramic handicraft during the movement of the ceramic handicraft, so as to ensure the stability of the ceramic handicraft during the movement and avoid the situation of shaking or tipping over of the ceramic handicraft when it is being towed.
