Description

Technical Field

[0001] The invention relates to the technical field of ceramic restoration, and in particular to a positioning device for bonding ancient ceramic fragments. Background Art

[0002] The existing ancient ceramic fragment splicing and positioning device plays a vital role in the field of ancient ceramic restoration. It is usually composed of a sturdy mechanical structure and advanced electronic components. The high-resolution image acquisition system equipped with the device is like a precision scanner, which can capture every detail of the ancient ceramic fragments in detail, whether it is exquisite patterns or subtle scratches. It can be clearly presented. Through complex and efficient algorithms and powerful software programs, the shape, color, texture and other information of the fragments are comprehensively analyzed and deeply processed, thereby providing detailed and accurate data support for the precise positioning of the fragments. At the same time, the device is equipped with a stable and reliable fixed platform, like a solid base, to ensure that the fragments always remain stable during the positioning process and are not disturbed by the outside world. In addition, it may also have complete data storage and management functions, which is convenient for restorers to check and compare the information of different fragments at any time, providing great convenience for restoration work. This device, with its scientificity and efficiency, provides a powerful means for the restoration of ancient ceramics, and is of great significance to the protection and inheritance of precious historical and cultural heritage.

[0003] When the existing mechanical seals are installed and used, there is a problem that the splicing parts cannot be adjusted, which brings many troubles to the restoration of ancient ceramics. When the ancient ceramic fragments are spliced, if the splicing parts cannot be adjusted, once a position deviation occurs, it may cause defects or even failure in the entire splicing work. For example, after the initial splicing, it is found that the angle or position between the two fragments is slightly deviated, but it is impossible to fine-tune it, which may make the texture of the splicing not perfectly fit, affecting the overall beauty and historical value of the ancient ceramics. Moreover, different fragments have different shapes and degrees of damage, and fixed splicing methods are difficult to adapt to various complex situations. This not only increases the difficulty and risk of restoration, but may also waste a lot of time and energy on re-splicing, reducing the efficiency and quality of the restoration work, and bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a positioning device for bonding ancient ceramic fragments. Summary of the invention

[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the multi-directional angle adjustment of ancient ceramic fragments can be achieved. Through the transmission of multiple bevel gears and the precise control of the servo motor, the movable rod drives the clamping support base to rotate, and the horizontal angle of the fragments can be adjusted. At the same time, the second servo motor drives the rotating frame to rotate as a whole through the worm and worm gear transmission, and further adjusts the angle of the fragments, which greatly improves the accuracy and flexibility of the fragment positioning and meets the repair needs of different fragments. Secondly, the horizontal position of the fragments can be adjusted. The second bevel gear drives the cylindrical gear, the second cylindrical gear and the third cylindrical gear to rotate in turn, and meshes with the limit gear plate to achieve the horizontal position adjustment of the fragments, so that the fragments can be more accurately positioned to the appropriate position during the splicing process. Furthermore, it has a stable fragment fixing function. After the fragments are placed on the clamping support base, the clamping block is squeezed through the limit groove, and the clamping block rotating in the movable groove clamps the fragments. The reset spring plays a buffering and reset role, ensuring that the fragments remain stable during the adjustment and splicing process, thereby improving the quality and efficiency of the repair work.

[0018] 2. In the present invention, by rotating the vacuum suction pump in the middle of the swing frame and connecting with the first connecting rod and the second connecting rod, the ancient ceramic fragments can be stably sucked for splicing operation. At the same time, the first electric telescopic rod and the second electric telescopic rod respectively push the first limit frame and the second limit frame to slide in the corresponding positioning sliding frame, so that the two limit frames are staggered. The reverse camshaft with a special elliptical staggered structure design can freely select ceramic fragments in the fragment placement area, which greatly improves the flexibility and accuracy of fragment selection. On the other hand, the third servo motor drives the reverse camshaft to rotate, and realizes the adjustment of the splicing edge of the fragments after picking up, which provides a guarantee for the precise splicing of the fragments. The third electric telescopic rod can adjust the height, and the stabilizing frame plays a stable supporting role. The fourth servo motor drives the swing frame to deflect and the fifth servo motor drives the first connecting rod to deflect, which can change the angle of picking up the fragments, so that the fragments can be better spliced, thereby improving the quality and efficiency of splicing of ancient ceramic fragments.

[0019] 3. In the present invention, after the fragments are sucked up by the vacuum suction pump and moved to the side of the cleaning brush, the sixth servo motor is started to drive the rotating positioning block to rotate, so as to accurately adjust the angular position of the fixed frame, thereby flexibly aligning the cleaning brush with the edges of the fragments at different positions. Then, the seventh servo motor is started to drive the first rotating block to rotate, thereby moving the first hinged rod. Due to the special diamond structure of the first hinged rod and the connection between the long rod and the hinge, the first hinged rod can push the slider to slide in the groove of the slide when it moves, driving the cleaning brush to approach or move away from the edge of the ancient ceramic fragments, thereby achieving efficient cleaning of the edge of the fragments. This design can automatically and accurately clean the edge of the fragments, provide clean and good splicing conditions for subsequent splicing of fragments, and improve the quality of splicing of ancient ceramic fragments and the overall restoration effect.
