[0052] The side of the pressing plate 106 close to the base 101 is movably connected with the quantitative bin 103, and the bottom of the pressing plate 106 is provided with a push plate 107.

[0053] The inside of the base 101 is provided with a single-rod pneumatic cylinder 309, the part of the driving rod of the single-rod pneumatic cylinder 309 that is inserted out of the base 101 is connected with a handle ball 108, and the handle ball 108 is arranged on one side of the push plate 107.

[0054] The controller controls the single-rod pneumatic cylinder 309.

[0055] As Figures 6-7As shown, the bottom of the connecting piece 503 is provided with an elastic sheet 507, the top of the connecting seat 301 is provided with a buckle 401 matched with the elastic sheet 507, and a clamping groove 601 for fixing the buckle 401 is formed in the elastic sheet 507. When the connecting piece 503 on the storage cabinet 102 is inserted into the lower connecting seat 301 from above at a certain angle and then rotated at a certain force, the storage cabinet 102 is connected with the connecting seat 301 successfully when the buckle 401 clamps the elastic sheet 507. When disassembled, the storage cabinet 102 can be conveniently taken out upward after the elastic sheet 507 is separated by rotating in the opposite direction.

[0056] The connecting seat 301 is internally provided with a bearing 310 sleeved on the lower rotating shaft 302, and the connecting piece 503 is internally provided with a sealing ring 501 sleeved on the upper rotating shaft 504 and the bearing 310. The sealing ring 501 can isolate the upper rotating shaft 504 from the storage cabinet 102, and the food in the storage cabinet 102 moves and falls into the meal box 109 through the quantitative cabinet 103 without contacting the upper rotating shaft 504, which is more sanitary and environmentally friendly.

[0057] The bottom of the rotating support 104 is provided with a fixed plate 508 connected with the scraping plate 201, and the bottom of the rotating support 104 is obliquely connected to the top of the fixed plate 508. The scraping plate 201 is symmetrically installed, and two scraping plates 201 are made of 4mm food-grade silica gel and have certain flexibility and hardness. The scraping plate 201 is installed on the fixed plate 508 and rotates synchronously with the lower rotating shaft 302 and the upper rotating shaft 504.

[0058] The bottom of the rotating support 104 is symmetrically provided with two scraping plates 201, and the bottom of each scraping plate 201 is provided with a notch 509. The number of notches 509 on the two scraping plates 201 is consistent or inconsistent.

[0059] The collaborative mechanical arm for scooping food in cooperation with the full-automatic quantitative distribution mechanism provided by the technical solution is completed by the mechanical arm combined with the vision system. First, the vision system judges the distribution of the food in the large food basin, and then the mechanical arm performs the scooping operation according to the analysis result, and the food in the large food basin is scooped and poured into the storage cabinet 102. The whole cycle generally needs 8-12 seconds, and the food distribution process needs to meet the production rhythm of 3-5 seconds / time. Therefore, the collaborative mechanical arm needs to scoop more than 3 portions of food from the large food tray each time, and pour it into the storage cabinet 102. The time for the controller to control the step motor 303 to rotate one circle (i.e. 360°) is set to 3 seconds. During the rotation, the scraping plate 201 scrapes the food in the storage cabinet 102 into the quantitative cabinet 103. After one rotation, the proximity sensor 308 transmits the sensing data of the sensing sheet 307 to the controller, and the controller controls the step motor 303 to pause.

[0060] When the meal box 109 reaches directly below the opening of the ration chamber 103, the photoelectric sensor detecting the position of the meal box 109 (the photoelectric sensor is arranged directly below the meal box 109, and the position is also directly below the ration chamber 103) feeds back the position information of the meal box 109 to the controller, and the controller controls the single-rod pneumatic cylinder 309 to work (the electromagnetic valve is electrified to switch), the driving rod of the single-rod pneumatic cylinder 309 is retracted, the pressing plate 106 is opened, and the dishes slide into the meal box 109 along the pressing belt 502 connected to the surface of the pressing plate 106 on the ration chamber 103;

[0061] Then the controller controls the driving rod of the single-rod pneumatic cylinder to extend, and the pressing plate 106 is pressed against the ration chamber 103 to complete the closing of the ration chamber 103;

[0062] After the full-automatic ration distribution mechanism distributes the dishes for three times, the mechanical arm adds dishes for one more time, and the capacity of the dish storage chamber 102 is designed to store 10 portions of dishes at the same time. Since the mechanical arm scoops more than three portions of dishes each time, the cumulative amount of stored dishes increases, and therefore, a weighing sensor (arranged at the bottom of the base 101) is arranged below the full-automatic ration distribution mechanism. When the total weight of the mechanism reaches the upper limit, the mechanical arm stops scooping dishes, and the distribution mechanism continues to distribute dishes. In this way, the amount of stored dishes in the dish storage chamber 102 continuously decreases.

[0063] When the total weight of the mechanism reaches the lower limit, the mechanical arm starts to scoop dishes into the dish storage chamber 102 again, and the process is repeated.

[0064] The technical scheme provided in the application reasonably solves the problems of easy disassembly and cleaning. The elastic sheet 507 and the buckle 401 in the quick insertion and quick disassembly structure are used to connect the ration assembly and the connecting seat 301. During installation, the connecting piece 503 on the dish storage chamber 102 is inserted into the lower connecting seat 301 at a certain angle from above, and then rotated at a certain force to make the buckle 401 clamp the elastic sheet 507. During disassembly, the dish storage chamber 102 is only needed to be rotated in the opposite direction, the elastic sheet 507 is separated, and then the dish storage chamber 102 can be conveniently taken out upward, which is convenient for cleaning the dish storage chamber 102. The ration assembly is arranged separately from the driving device at the top of the base 101 and is provided with a sealing ring 501, which can prevent the dishes from contacting the upper rotating shaft 504 when moving in the dish storage chamber 102, and is more sanitary and environmentally friendly. The single-rod pneumatic cylinder 309 for pushing the pressing plate 106 is additionally arranged. The single-rod pneumatic cylinder 309 works to drive the handle ball 108 to push the push plate 107, so that the pressing plate 106 is closed and opened with the ration chamber 103, and the process of placing dishes is completed.

[0065] The technical scheme provided in the application reasonably solves the problem of soup. One of the characteristics of Chinese food is that most dishes contain a certain amount of soup and oil. During the process of distributing dishes, the distribution, anti-dripping, anti-splashing and other problems of soup need to be solved. In the present application, the problem is solved through the design of five aspects:

[0066] 1. The base 101 (integrated mechanism) is tilted backward at an angle of approximately 6-8 degrees to the plane (see attached diagram for details). Figures 1-2 In this way, when the robotic arm scoops multiple portions of vegetables into the storage bin 102, the broth will be temporarily stored in the opposite area of ​​the outlet 105, preventing it from dripping from the outlet 105.

[0067] 2. Several notches 509 are cut into the lower part of the scraper 201 (silicone scraper 201), and the notches 509 of the two scrapers 201 are in different positions. When scraping vegetables, some soup will not be scraped into the measuring chamber 103, which can play a certain role in soup mixing.

[0068] like Figures 8-10 As shown, the bottom opening of the metering chamber 103 and the pressure plate 106 are both designed to be inclined, with baffles on three sides. The angle of inclination with the plane is about 11-13 degrees. In this way, when the soup enters the metering chamber 103, the soup will be concentrated at the rear of the pressure plate 106 and temporarily stored to prevent leakage from the gap or outlet. Only when the pressure plate 106 is opened will the soup flow out from the outlet 105.

[0069] 4. Set the opening time of the quantitative bin 103 reasonably, and reduce the opening speed of the one-way cylinder while meeting the production cycle.

[0070] 5. A baffle is provided on the outer ring of the outlet of the pressure plate 106 to form a "follow-up fence". When the pressure plate 106 is opened, the "follow-up fence" will descend to a position below the upper surface of the food box and surround the three sides of the food box. If the dish contains a lot of soup, when it slides into the food box, even if some juice splashes out, it will be blocked by the "follow-up fence" and flow along the wall into the groove. It can be cleaned after the work is completed.

[0071] The technical solution provided in this application reasonably solves the problem of viscosity: some dishes have a high viscosity after cooking and thickening, which will stick to the wall of the metering chamber 103 or the surface of the pressure plate 106 during the falling process, resulting in inaccurate metering. In actual use, a pressure belt 502 (a piece of food-grade soft cloth) is designed to be added to the rear wall of the metering chamber 103 and the discharge port of the pressure plate 106. When the pressure plate 106 is opened 30-40 degrees, the pressure belt 502 is straightened. At this time, the angle between the pressure belt 502 and the plane can reach 60-70°. At the same time, when the pressure plate 106 is opened, the pressure belt 502 has a "springing" action, which helps the dishes to slide down quickly.

[0072] In summary, the full-automatic quantitative dispensing mechanism of the application adopts the elastic sheet and the buckle with quick insertion and quick disassembly structure to connect the quantitative assembly and the connecting seat, only needs to insert the connecting piece on the food storage bin into the lower connecting seat from above at a certain angle, then rotates with a certain force to make the buckle clamp the elastic sheet during installation, only needs to rotate the food storage bin in the opposite direction during disassembly, the elastic sheet is separated, and then the food storage bin can be conveniently taken out upward, which is convenient for cleaning of the food storage bin; the quantitative assembly is installed on the top of the base and is separated from the driving device, and is provided with a sealing ring, which can prevent the food from contacting the upper rotating shaft when moving in the food storage bin, and is more sanitary and environmentally friendly; the single-rod cylinder for pushing the pressing plate is additionally arranged, the single-rod cylinder works to drive the handle ball to push the pressing plate, so that the pressing plate is closed and opened with the quantitative bin, the process of putting food is completed, and the structure is simple and convenient to use.
