Description

Technical Field

[0001] The utility model relates to the technical field of automatic cooking equipment manufacturing, in particular to a multifunctional kitchen robot arm tool switching mechanism. Background Art

[0002] Kitchen knives are tools used in the kitchen for cutting, slicing, and chopping. They generally include different types, such as kitchen knives, fruit knives, and boning knives. Kitchen knives are commonly used for daily chopping vegetables and meat; fruit knives are more compact and are specifically used for peeling fruit; boning knives are heavier and are used to cut through harder ingredients such as bones. Kitchen knives are made of materials such as stainless steel and high-carbon steel, each with different characteristics. For example, stainless steel knives are rust-resistant and easy to clean, while high-carbon steel knives are sharper but require careful maintenance to prevent rust. The use of a multi-functional kitchen robot arm knife switching mechanism can improve efficiency, ensure safety, versatility, and precise control. Traditional multi-functional kitchen robot arm knife switching mechanisms have slow switching speeds, low positioning accuracy, low reliability, high maintenance costs, and occupy a large space.

[0024] Specifically, starting the hydraulic rod 2 can drive the push rod body 3 to move downward, causing the connecting shaft 4 to move. The movement of the connecting shaft 4 can drive the rotating plate 5 to rotate, causing the switching rod 7 to rotate. The switching rod 7 can rotate and drive the rotating rod 8 to move, causing the connecting plate 9 to move at the same time. When the push rod body 3 moves downward, it drives the connecting rod 10 downward and drives the rotating shaft 6 at the same time.

[0029] Working principle: When the device needs to be used, the hydraulic rod 2 is started to drive the push rod body 3 to move downward to move the connecting shaft 4. The movement of the connecting shaft 4 drives the rotating plate 5 to rotate to rotate the switching rod 7. The rotation of the switching rod 7 drives the rotating rod 8 to move so that the connecting plate 9 moves at the same time. The push rod body 3 moves downward and drives the connecting rod 10 downward and drives the rotating shaft 6 at the same time, so that the device can accurately move the tool to the specified position; when the tool needs to be removed, the electric push rod 14 drives the driving block 15 to move and drives the roller 16 to move. The movement of the roller 16 drives the clamping claw 17 to rotate so that the clamping block 19 releases the tool. After the tool is replaced, the compressed first spring 22 rebounds and pushes The clamping jaws 17 return to their original positions, and the electric push rod 14 simultaneously pulls back the driving block 15, so that the clamping jaws 17 and the clamping block 19 clamp the knife to complete the clamping. When impacted, the second spring 24 undergoes elastic deformation, causing the stabilizing block 25 to move, thereby reducing the impact of the impact force on the clamping jaws 17. This device not only solves the problem that the traditional kitchen knife replacement method mainly relies on manual operation, which is not only inefficient but also has certain safety risks, causing the chef to frequently change knives to handle different ingredients. This process is not only time-consuming, but also easily distracts the chef's attention, thereby causing problems affecting cooking efficiency and quality. At the same time, it also solves the purpose of slowly removing worn knives.
