[0066] like Figures 1 to 8 As shown, the food pre-processing mechanism of the cooking robot in this embodiment includes: a medium tank 100, a base 200, a strainer 300, a stirring head component 400, a stirring part transmission structure 600, and a lifting drive structure 700; the medium tank 100 is disposed on the base 200, the strainer 300 is placed in the medium tank 100, and a strainer flipping structure 500 is provided on the base 200;
[0067] The stirring unit transmission structure 600 includes a stirring unit translation electric actuator 610, a translation mounting plate 620, multiple columns 630, an annular disc 640, and a baffle 650. The stirring unit translation electric actuator 610 is fixedly installed and connected to the translation mounting plate 620. The stirring unit translation electric actuator 610 can push the translation mounting plate 620 to move horizontally. The top of all columns 630 is connected to the bottom surface of the translation mounting plate 620, and the bottom of all columns 630 is connected to the top surface of the annular disc 640. A circular recessed groove 641 is provided on the inner circumferential surface of the annular disc 640. The baffle 650 is horizontally installed, and both ends of the baffle 650 are inserted into the circular recessed groove 641. A plate through-hole 651 is provided on the top surface of the baffle 650.
[0068] The lifting drive structure 700 includes a lifting mounting plate 710, a lifting electric actuator 720, a lifting actuator bracket 730, and a stirring drive motor 740. The lifting mounting plate 710 is connected to a translation mounting plate 620. The lifting electric actuator 720 is mounted on the lifting mounting plate 710 and connected to the lifting actuator bracket 730. The lifting electric actuator 720 can drive the lifting actuator bracket 730 to move vertically. The stirring drive motor 740 is mounted on the lifting actuator bracket 730.
[0069] The stirring head assembly 400 includes a stirring support rod 410 and multiple stirring rods 420; the stirring support rod 410 is connected to the stirring drive motor 740 and is horizontally arranged; all the stirring rods 420 are vertically arranged, and the upper end of all the stirring rods 420 is connected to the stirring support rod 410, and all the stirring rods 420 are arranged sequentially along the length of the stirring support rod 410; the lower end of all the stirring rods 420 passes through the plate through-hole 651.
[0070] The stirring drive motor 740 drives the stirring part support rod 410 to rotate, the stirring part support rod 410 drives all the stirring rods 420 to rotate, and all the stirring rods 420 drive the baffle 650 to rotate.
[0071] The food pre-processing mechanism of this cooking robot, before food needs to be added to the strainer 300 of the medium tank 100, can cause the lifting electric push rod 720 to move the lifting push rod bracket 730 upward, the lifting push rod bracket 730 to move the stirring drive motor 740 upward, the stirring drive motor 740 to move the stirring part support rod 410 upward, and the stirring part support rod 410 to move the stirring rods 420 upward, with the lowest point of all the stirring rods 420 above the medium tank 100; the stirring part translation electric push rod 610 drives the translation mounting plate 620 to move away from the medium tank 100, the translation mounting plate 620 to move all the columns 630, the annular disc 640 and the lifting drive structure 700 away from the medium tank 100, and the stirring part transmission structure 600, the lifting drive structure 700 and the stirring head component 400 reach their initial positions; when food is added to the strainer 300... After the ingredients are added and the strainer 300 is returned to the medium tank 100, the electric actuator 610 of the stirring section drives the sliding mounting plate 620 to move directly above the medium tank 100. The sliding mounting plate 620 then moves all the columns 630, the annular disc 640, and the lifting drive structure 700 directly above the medium tank 100. The lifting actuator 720 moves the lifting actuator bracket 730 downward, which in turn moves the stirring drive motor 740 downward. The stirring drive motor 740 then moves the stirring section support rod 410 downward, which in turn moves the stirring rods 420 downward, placing them inside the strainer 300. The stirring drive motor 740 then rotates the stirring section support rod 410, which in turn rotates all the stirring rods 420, which in turn rotate the baffle 650. The stirring rods 420 rotate intermittently in both directions to thoroughly mix the ingredients. After mixing is finished, the mixing head component 400 is moved upward. When all the mixing rods 420 pass the baffle 650, the food hanging or stuck on the mixing rods 420 will be blocked and fall back into the strainer 300. Then the mixing transmission structure 600, the lifting drive structure 700 and the mixing head component 400 are withdrawn to their initial positions.
[0072] Therefore, when the stirring head component 400 stirs the ingredients in the medium tank 100, the baffle 650 will rotate synchronously with the stirring rod 420. When the stirring rod 420 is moved upward, as the stirring rod 420 passes through the baffle 650, the baffle 650 can block the food hanging on the stirring rod 420 and make the food fall down. Thus, the stirring head component 400 can stir the ingredients evenly. The baffle 650 can effectively prevent food from sticking to the stirring rod 420 or food from being stuck on the stirring rod 420.
[0073] In this embodiment, the annular disc 640 includes a mounting base plate 642 and a limiting cover plate 643 disposed on the top surface of the mounting base plate 642.
[0074] The sieve tilting structure 500 includes a tilting bracket 510, a tilting drive motor 520, a tilting input gear 530, a tilting output gear 540, and a tilting shaft 550. The tilting bracket 510 is mounted on the base 200, the tilting shaft 550 is mounted on the tilting bracket 510, the sieve component 300 is mounted on the tilting shaft 550, the tilting output gear 540 is fixedly sleeved on the tilting shaft 550, the tilting drive motor 520 is mounted on the tilting bracket 510, and the drive shaft of the tilting drive motor 520 is connected to the tilting input gear 530, which meshes with the tilting output gear 540. The tilting drive motor 520 drives the tilting input gear 530 to rotate, which in turn drives the tilting output gear 540 to rotate, which in turn drives the tilting shaft 550 to rotate. The tilting shaft 550 causes the sieve component 300 to tilt and move between the processing position inside the pool and the feeding position outside the pool. The transmission method of the flip input gear 530 and the flip output gear 540 can greatly increase the reliability of use.
[0075] The stirring unit transmission structure also includes a fixed stirring unit guide shaft 660, the central axis of which is parallel to the direction in which the stirring unit translation electric actuator 610 pushes the translation mounting plate 620 to move. A stirring unit linear bearing 670 is mounted on the stirring unit guide shaft 660 and is connected to the translation mounting plate 620. Since the guiding direction of the stirring unit guide shaft 660 is parallel to the direction in which the stirring unit translation electric actuator 610 pushes the translation mounting plate 620 to move, the arrangement of the stirring unit guide shaft 660 and the stirring unit linear bearing 670 ensures that the translation mounting plate 620 can move smoothly.
[0076] The lifting mounting plate 710 is provided with a vertical rail 711, and the lifting push rod bracket 730 is provided with a slider 731, which can move up and down along the vertical rail 711. The slider 731 and the vertical rail 711 can play a guiding role, so that the lifting mounting plate 710 can move stably along the vertical direction.
[0077] The bottom of the medium pool 100 has a pool body storage cavity 110, and the top of the base 200 is embedded in the pool body storage cavity 110 of the medium pool 100. Thus, the medium pool 100 and the base 200 form an embedded structure with a larger top and a smaller bottom, which effectively prevents external water or oil from entering the base 200.
[0078] The base 200 has an opening 210 at its top, and a heating plate 220 is provided inside the base 200. The heating plate 220 can be removed from the top of the base 200 after the medium pool 100 is removed.
[0079] The top surface of the pool housing cavity 110 has an upwardly protruding convex structure 120. The convex structure 120 avoids deformation caused by thermal expansion and contraction after heating the medium pool 100, and facilitates inspection and maintenance.
[0080] A temperature sensor 900 is mounted on the medium tank 100. The temperature sensor 900, the tilting drum structure 20, the heating plate 220, the tilting drive motor 520, the stirring section translation electric actuator 610, the lifting electric actuator 720, and the stirring drive motor 740 are all connected to the controller 800. The controller 800 controls the operation of the tilting drum structure 20, the heating plate 220, the tilting drive motor 520, the stirring section translation electric actuator 610, the lifting electric actuator 720, and the stirring drive motor 740. The temperature sensor 900 transmits the sensed temperature of the liquid in the medium tank 100 to the controller 800.
[0081] When the controller 800 receives a signal to trigger automatic lubrication or blanching, the heating plate 220 in the base 200 begins heating. When the temperature sensor 900 detects that the temperature of the liquid in the medium tank 100 has reached the preset temperature, the strainer 300 in the medium tank 100 automatically lifts, raising the strainer 300 slightly above the surface of the liquid in the medium tank 100 to prevent splashing of the liquid after food is added. Then, the required food is automatically added to the strainer 300 by the automatic feeding mechanism above. After the ingredients are added, the strainer 300 returns to the oil or water tank. At the same time, the sliding mounting plate 620 moves all the columns 630, the annular disc 640 and the lifting drive structure 700 to the top of the medium tank 100. Then, the stirring rod 420 moves down into the strainer 300. The stirring rod 420 rotates intermittently in both directions to stir the food evenly. At this time, the controller 800 also uses the feedback from the temperature sensor 900 to accurately control the temperature of the liquid in the medium tank 100 in real time.
[0082] After the stirring transmission structure 600, the lifting drive structure 700, and the stirring head component 400 are retracted to their initial positions, the stirring action is completed. At the same time, the strainer flipping structure 500 drives the strainer component 300 to automatically lift above the oil or surface, and begin to drain oil or water. After waiting for the cooking command, the strainer flipping structure 500 continues to drive the strainer component 300, so that the ingredients are put into the flipping drum structure 20.
[0083] The food pre-processing mechanism of the cooking robot can automatically add ingredients and then automatically grease, blanch, and stir. After the ingredients are evenly stirred during the grease or blanching process, the stirring rod 420 can be withdrawn to prevent the ingredients from getting stuck or sticking, thereby improving the reliability of the stirring head component 400.
[0084] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0085] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
