Description

Technical Field

[0001] This utility model relates to a wok flipping drive device and a wok for a cooking robot. Background Technology

[0002] With economic development, people are pursuing higher and higher quality of life. In the catering industry, which is closely related to people's lives, cooking robots are receiving more and more attention from ordinary people and catering operators.

[0003] The wok is the core component of the cooking robot; the current popular cooking robot works by placing the wok horizontally while cooking, and flipping it over when the food needs to be poured out.

[0004] Chinese patent CN203263022U discloses an automatic cooking robot's wok-twisting transmission mechanism. This mechanism uses flexible steel wire ropes fixed to pulleys at both ends to drive the wok handle shaft, enabling the wok to flip at any angle, thus facilitating the removal of food from the wok or washing it before removing it from the wok. This wok-twisting mechanism is relatively complex.

[0005] Additionally, Chinese patent publication number 215271987U discloses an automatic pot-washing device for a cooking robot, comprising a pot body, a tilting shaft, a fork shaft, a driven shaft, a fork, and a water inlet pipe. The pot body is symmetrically equipped with a first bushing and a second bushing. A fork is located inside the pot body. The fork shaft is housed within the first bushing, and the driven shaft is housed within the second bushing. One end of the fork is fixedly connected to the fork shaft, and the other end is fixedly connected to the end of the driven shaft that extends into the pot body. The tilting shaft is sealed at the outer end face of the second bushing and fixedly connected to it. The tilting shaft and the driven shaft are coaxially arranged, and both have horizontal holes. The water inlet pipe passes through the horizontal hole of the tilting shaft and is inserted into the horizontal hole of the driven shaft. A bearing and a sealing ring are provided between the water inlet pipe and the driven shaft. The horizontal hole of the driven shaft communicates with the inner cavity of the pot body. This tilting device is integrated with a water supply device.

[0006] Because the wok itself is quite heavy, and with the addition of components such as the heating coil, the overall weight of the wok is considerable, thus requiring a high-power motor to drive its rotation.

[0007] It is necessary to design a drive device that can be driven to rotate using a low-power motor. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide a wok flipping drive device and wok for a cooking robot. The wok flipping drive device and wok of the cooking robot have a compact structure and are easy to implement.

[0009] The technical solution of the utility model is as follows: A wok-flipping drive device for a cooking robot, including a drive mechanism; The drive mechanism includes a motor and a bevel gear set; The outer wall of the wok body has a first connecting piece and a second connecting piece at two opposite positions, serving as the fulcrum for rotation. "Opposite" means that the first and second connecting pieces are symmetrical about the central axis of the wok body. A driven shaft is inserted into the first connecting piece, and the driven shaft is connected to the wok support frame in sequence via bearings and bearing seats. A drive shaft is inserted into the second connecting piece, and a motor is connected to the drive shaft via a bevel gear set to drive the wok body to rotate, typically by 90-110 degrees. The drive shaft is mounted on the housing of the drive mechanism via bearings and bearing seats.

[0010] The drive mechanism also includes a reducer located between the motor shaft and the bevel gear set (a reducer may not be necessary when using a stepper motor). The motor is controlled by the controller of the cooking robot.

[0011] It also includes tension springs and rotary linkage components; The rotary linkage is fixed on the driven shaft; The wok support frame is equipped with a first tension spring mounting post, and the rotating linkage is equipped with a second tension spring mounting post. The two ends of the tension spring are respectively hung on the first tension spring mounting post and the second tension spring mounting post, and the tension spring is in a stretched state when the wok is in a flat position.

[0012] A wok, comprising a wok body and a wok-flipping drive device for the cooking robot. Beneficial effects

[0013] The wok-flipping drive device and wok of this utility model cooking robot use a motor, reducer and bevel gear set as the core drive and transmission mechanism to drive the wok to flip. It has a compact structure and reasonable layout.

[0014] In addition, the biggest highlight of this utility model is that it uses a tension spring to provide some prestress for the flipping of the wok. Under the tension of the tension spring, the motor only needs a small torque to drive the wok to flip. Therefore, a smaller power drive motor can be selected, which occupies less space and has a lower cost. Moreover, under the action of the tension spring, the wok shakes less during the flipping process, and the action is smoother. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: As Figure 1-4 As shown, a wok-flipping drive device for a cooking robot includes a drive mechanism. The drive mechanism includes a motor 14, a reducer 13, and a bevel gear set 10; The outer wall of the wok body 35 has two opposite connecting parts, namely a first connecting part 21 and a second connecting part 22, which serve as the fulcrum for rotation of the wok. "Opposite" means that the first and second connecting parts are symmetrical with respect to the central axis of the wok body. A driven rotating shaft 8 is inserted into the first connecting part, and the driven rotating shaft is connected to the wok support frame 6 in sequence via bearings 7 and bearing seats 39. A transmission shaft 9 is inserted into the second connecting part. The output shaft of the motor is reduced in speed by a reducer and then connected to the transmission shaft via a bevel gear set to drive the wok body to rotate, typically by 90-110 degrees. The transmission shaft is mounted on the housing of the drive mechanism via bearings and bearing seats. The housing of the drive mechanism and the wok support frame together support the rotation of the wok.

[0021] The motor is controlled by the controller of the cooking robot.

[0022] The wok-flipping drive device of the cooking robot also includes a tension spring 34 and a rotary linkage component 36; The rotary linkage is fixed on the driven shaft; The wok support frame is provided with a first tension spring mounting post 37, and the rotating linkage is provided with a second tension spring mounting post 38; The two ends of the tension spring are respectively hung on the first tension spring mounting post and the second tension spring mounting post, and the tension spring is in a stretched state when the wok is in a flat position.

[0023] A wok, comprising a wok body 35 and a wok flipping drive device for the cooking robot.

[0024] The working process of this utility model is described as follows: The wok is rotated by a motor and a reducer. The bevel gear set drives the transmission shaft to rotate, thereby realizing the rotation of the wok assembly. One end of the tension spring is hooked on the rotating linkage (also known as the connecting plate) of the wok assembly, and the other end is hooked on the frame. When the wok assembly is in position 1 (flat position, i.e., the cooking position, see...), Figure 2 When the spring is stretched to its limit and the force is at its maximum, the wok assembly rotates to position 2 (the flipped position, i.e., the dish-dispensing state, see [link]). Figure 3 The tension spring is slightly stressed; when the food is being served, it moves from position 1 (cooking position) to position 2 (serving state), and the tension spring provides a portion of the tension (prestress); this structure can reduce the torque required by the motor and also solve the problem of vibration during the mechanism's rotation.

[0025] Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
