Abstract

The invention relates to a single-degree-of-freedom occlusion robot applied to food and dental monitoring. The robot comprises a static platform, a power device and a transmission device; the power device and the transmission device are in transmission connection with each other and are both arranged at the upper end of the static platform, an upper jaw fixed platform and a lower jaw adjustable platform are further up and down oppositely arranged at the upper end of the static platform, an upper jaw mounting platform is rotatably connected with the transmission device, and the lower jaw adjustable platform is slidingly connected with the static platform; the lower jaw adjustable platform includes a sliding flat plate, the upper end of the sliding flat plate is provided with a lower jaw mounting platform, and the lower jaw mounting platform is connected with the sliding flat plate through a platform lifting assembly; the upper jaw fixed platform and the jaw mounting platform are also provided with monitoring systems. The robot can simulate the occlusion process of teeth, the deformation state of food in the occlusion process is observed, the force bearing condition of a tooth modelis monitored through the monitoring systems, and therefore for different kinds of food, the whole force bearing conditions of the teeth in the occlusion process can be detected and analyzed.

Description

technical field [0001] The invention relates to the technical field of robots, and more specifically relates to a single-degree-of-freedom occlusal robot applied to food and dental detection. Background technique [0002] Food problems and oral problems have always been the focus of attention. The properties of food will directly affect the chewing form and muscle strength of human beings, which will have an important impact on human oral health. The development of new food, food quality inspection, etc. all require reasonable and scientific testing, and the testing of food attributes usually uses instrumental analysis and sensory evaluation. Instrumental analysis is to use different food testing equipment to test the physical or mechanical properties of food, and at the same time analyze the test signal to analyze the food properties. [0003] Although the pressure testing machines on the market can also detect the mechanical and physical properties of substances, on the ...
