Description

Technical Field

[0001] The present application relates to cooking equipment, and in particular to a cooking robot with a pot-turning mechanism. Background Art

[0002] With the continuous development of automated, intelligent, and information-based technologies, the automation of cooking equipment has gradually become a hot topic, with several cooking robots appearing on the market. The chemical coating on the inner pot of existing cooking robots has a lifespan of no more than 700 cycles, requiring re-coating after a certain period of use. This is particularly true for commercial cooking robots, which, if they cook 100 dishes a day, will need to disassemble the inner pot for maintenance every week. The inner pot is typically secured to the rotating pot shaft with screws or threaded compression caps, requiring manual removal, which is time-consuming and labor-intensive. Similarly, the installation process requires manual intervention, and this manual disassembly and installation increases user and training costs. Summary of the Invention

[0004] The technical problem to be solved by this application is solved by the following technical solutions:

[0010] A shaft locking assembly includes a shaft locking ring and a clamping shaft sleeved on the rotary pot shaft, wherein the shaft locking ring is sleeved on the clamping shaft, and the shaft locking motor is driven to lock the clamping shaft or separate the shaft locking ring from the clamping shaft;

[0011] The electric locking shaft mechanism and the pot rotating mechanism are arranged on a mounting plate, the mounting plate is arranged in the accommodating cavity, and the pot rotating shaft is passed through the pot inner opening and the lining opening.

[0012] The cooking robot with a pot-turning mechanism provided in an embodiment of the present application comprises a pot drum, a pot-turning mechanism, an electric shaft-locking mechanism and a mounting plate; the pot drum comprises an outer shell, an inner lining and a pot core, and a pot core opening is provided at the bottom of the pot core; the inner lining sleeve is provided on the outside of the pot core, and an inner lining opening is provided at the bottom of the inner lining; an accommodating cavity is provided between the outer shell and the inner lining; the pot-turning mechanism comprises a pot-turning assembly, and the pot-turning assembly comprises a pot-turning shaft; the electric shaft-locking mechanism comprises: a shaft-locking motor and a bidirectional lead screw, and the bidirectional lead screw is provided on the output shaft of the shaft-locking motor; the shaft-locking assembly comprises a shaft-locking ring and a clamping shaft, and the shaft-locking ring sleeve is provided on the clamping shaft; the electric shaft-locking mechanism and the pot-turning mechanism are provided on the mounting plate, and the mounting plate is provided in the accommodating cavity, and the pot-turning shaft passes through the pot core opening and the inner lining opening.
