[0002] In large restaurants or chain restaurants, automatic meal delivery robots can replace part of the waiters, responsible for delivering meals from the kitchen to the customer's table, reducing the burden on manual labor and improving service efficiency.

[0003] In large restaurants and chain restaurants, customers will order soup food, and soup dishes are used to hold soup food, and the weight of soup food itself is relatively large, and the heat of freshly cooked soup food is relatively high, and in order to reduce the burden on manual labor, the stability of the existing automatic meal delivery robot is high, so the automatic meal delivery robot is used to deliver soup food.

[0004] However, during the delivery of soup food, the temperature of freshly cooked soup food is usually above 80℃, and the metal or ceramic soup dish will quickly conduct heat at high temperature, causing the temperature of the edge of the dish to rise significantly. When the meal delivery robot reaches the meal delivery point, the customer or the waiter will take off the soup dish, and the edge of the soup dish will have a large amount of heat, and the waiter or customer will lose stability when directly touching it due to the hot hand.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figures 1-2 A robot with automatic food delivery function includes a robot body 1 and a food delivery box 2 set on the robot body 1. Multiple food delivery boxes 2 are provided and are installed on the robot body 1 from bottom to top.

[0048] The bottom of the delivery box 2 is equipped with a positioning ring 21, which is used to position the bottom of the soup plate 3.

[0049] The food delivery box 2 has openings 22 on both sides inside, and a side shell 4 is provided on the outside of the opening 22. An insulated door 24 is provided at the opening 22. A take-out opening 23 is provided on one side of the food delivery box 2. A closing door 5 is provided on both sides of the take-out opening 23. A synchronous drive 6 is provided inside the food delivery box 2. The synchronous drive 6 is used to open and close the closing door 5. The synchronous drive 6 is connected to the two insulated doors 24.

[0050] The top of the inside of the food delivery box 2 is provided with a partition 25, and the synchronous drive component 6 is installed on the partition 25;

[0051] Please see Figures 1-5 The synchronous drive component 6 includes a rotating shaft 61, a rotating component 62, a rotating support rod 63, a fixed shaft 64, a rotating support rod 65, and a linkage component 66. The rotating shaft 61 is rotatably connected to the partition plate 25. The rotating component 62 is installed on the partition plate 25 and is used to drive the rotating shaft 61. One end of the rotating support rod 63 is fixedly connected to the rotating shaft 61, and the fixed shaft 64 is fixedly installed on the other end of the rotating support rod 63. There are two rotating support rods 65, which are arranged sequentially on the fixed shaft 64. One end of each of the two push shafts is rotatably connected to the fixed shaft 64. The other end of the rotating support rod 65 is fixedly connected to the top of the inner side of the closed door 5 through a hinge support.

[0052] There are two linkage components 66, which are located between the closed door 5 and the insulating door 24.

[0053] The linkage 66 includes a first linkage shaft 661, a second linkage shaft 662, a driving helical gear 663, and a driven helical gear 664. The first linkage shaft 661 is fixedly inserted through the closed door 5, and both ends of the first linkage shaft 661 are rotatably connected to the take-out opening 23. The second linkage shaft 662 is fixedly inserted through one end of the door 24, and one end of the second linkage shaft 662 is rotatably connected to the inner wall of the opening 22.

[0054] The other end of the second linkage shaft 662 is fixedly connected to the driven helical gear 664. The driven helical gear 664 is meshed with the driving helical gear 663. The closed door 5 is provided with a groove corresponding to the position of the driving helical gear 663, and the driving helical gear 663 is fixedly sleeved on the outside of the first linkage shaft 661.

[0055] Please see Figures 5-6 The bottom of the door 24 is provided with a movable groove 241, and an extension plate 242 is slidably provided at the movable groove 241. Both sides of the door 24 are provided with movable openings 243, and the movable openings 243 are connected to the movable groove 241. A guide rod 244 is slidably passed through the movable opening 243. One end of the guide rod 244 is fixedly connected to the extension plate 242. The inner wall of the side shell 4 is provided with a guide groove 245, and the other end of the guide rod 244 is slidably connected to the guide groove 245.

[0056] In this application, the rotating component 62 includes a telescopic cylinder 621, a push rack 622, and a push gear 623. The telescopic cylinder 621 is fixedly installed on the partition plate 25, and the output end of the telescopic cylinder 621 is fixedly connected to the push rack 622. The push rack 622 is meshed with the push gear 623, and the push gear 623 is fixedly sleeved on the outside of the rotating shaft 61.

[0057] Specifically: when the robot body 1 delivers soup-type food and puts the soup plate 3 containing the soup into the delivery box, or when it takes the soup plate 3 out of the delivery box 2;

[0058] The telescopic cylinder 621 operates, which in turn pushes the rack 622 to move. While pushing the rack 622 to move, it drives the push gear 623 to rotate synchronously. While the push gear 623 rotates, it drives the rotating shaft 61 to rotate relative to the partition 25. While the rotating shaft 61 rotates, it drives the two push rods 94 to rotate synchronously through the rotating support rod 63 and the fixed shaft 64. Because the push rods 94 are connected to the closing door 5, the two closing doors 5 are further rotated relative to the take-out opening 23. While the closing door 5 rotates, it drives the first linkage shaft 661 to rotate. The first linkage shaft 661 drives the driven gear to rotate through the driving gear, which in turn drives the second linkage shaft 662 to rotate the door 24 relative to the opening 22.

[0059] Furthermore, in this application, due to the limiting effect of the extension plate 242, guide rod 244 and guide groove 245, the extension plate 242 rotates synchronously with the door 24 and moves along the inside of the door 24, thereby realizing the synchronous opening of the opening 22.

[0060] Please see Figures 7-15 The side shell 4 is fixedly installed on the outside of the food delivery box 2, and the side shell 4 is equipped with an anti-scalding mechanism 7. When the robot body 1 delivers soup to the pick-up point, the synchronous drive 6 drives the two closed doors 5 to open, and at the same time drives the two insulated doors 24 to open. Subsequently, the two anti-scalding mechanisms 7 operate synchronously.

[0061] The anti-scalding mechanism 7 includes a rotating shaft 71, a reciprocating pick-and-place latch 72, an intermittent drive 73, a drive motor 74, a drive rod 75, a mating and advancing part 76, and an anti-scalding ear 77. The rotating shaft 71 passes through one side of the side shell 4 and is rotatably connected to the side shell 4. One end of the rotating shaft 71 located inside the side shell 4 is connected to the reciprocating pick-and-place latch 72.

[0062] The reciprocating pick-and-place clamp 72 includes a rotating disk 721, a synchronous shaft 722, a synchronous support rod 723, a traction shaft 724, a traction plate 725, a guide member 8, and a clamping member 9. One end of the rotating shaft 71 is fixedly connected to the rotating disk 721. The synchronous shaft 722 is fixedly installed on the other side of the rotating disk 721, and the synchronous shaft 722 is offset from the center of the rotating disk 721. One end of the synchronous support rod 723 is rotatably sleeved on the outside of the synchronous shaft 722, and the other end of the synchronous support rod 723 is rotatably connected to the traction plate 725 through the traction shaft 724.

[0063] The guide member 8 is mounted on the traction plate 725 and is connected to the clamping member 9. The inner wall of the side shell 4 is provided with a fixing plate 726 and a guide groove 7261 is provided on the fixing plate 726. One end of the guide member 8 is connected to the guide groove 7261.

[0064] The guide member 8 includes a support rod 81, a swing plate 82, and a swing rod 83. The support rod 81 passes through the traction plate 725 and is rotatably connected to the traction plate 725. One end of the support rod 81 is fixedly connected to the clamping member 9, and the other end of the support rod 81 is fixedly connected to the swing plate 82. One end of the swing rod 83 is fixedly installed on the swing plate 82, and the other end of the swing rod 83 is slidably connected to the guide groove 7261.

[0065] As a further explanation, the guide groove 7261 consists of two transverse edge segments and a V-shaped middle segment. When the swing rod 83 moves along the guide groove 7261, the swing rod 83 drives the swing plate 82 to rotate relative to the traction plate 725 due to the limiting effect of the V-shaped middle segment. When the swing plate 82 rotates, the support rod 81 rotates synchronously. In this application, the V-shaped middle segment allows the support rod 81 to rotate 180°.

[0066] Please see Figures 11-12 The clamping component 9 includes a heat insulation shell 91, an electric push rod 92, a push block 93, a push support rod 94, and a clamping plate 95. One end of the support rod 81 is fixedly connected to the heat insulation shell 91. The electric push rod 92 is fixedly installed inside the heat insulation shell 91. The output end of the electric push rod 92 is fixedly connected to the push block 93. There are two push support rods 94. One end of each push support rod 94 is rotatably connected to the push block 93 through a pin, and the other end of the push support rod 94 is rotatably connected to the clamping plate 95 through a pin.

[0067] The heat insulation shell 91 is provided with a limiting port, and two clamping plates 95 are slidably connected to the outside of the limiting port. The two clamping plates 95 clamp and fix the anti-scalding ears 77 to each other.

[0068] In this application, the two clamping plates 95 are set according to the shape of the two sides of the anti-scalding ears 77, so that the two clamping plates 95 stably clamp the two anti-scalding ears 77.

[0069] Specific implementation process: In this application, a temperature sensor can also be installed inside the food delivery box 2. The temperature sensor is used to monitor the temperature inside the food delivery box 2 in real time. That is, when the temperature exceeds the rated range, when taking out the soup plate 3 containing soup, both the take-out port 23 and the opening 22 will be opened first.

[0070] Before opening, the heat insulation shell 91 is located inside the side shell 4, and the heat insulation shell 91 faces the anti-scalding ear 77, and the two clamping plates 95 clamp and fix one of the adjacent anti-scalding ears 77.

[0071] When activated, the drive motor 74 runs, causing the rotating shaft 71 to rotate. As the rotating shaft 71 rotates, it drives the rotating disk 721 to rotate. The rotating disk 721 then pushes the traction plate 725 through the synchronous support rod 723. Due to the limiting effect of the swing plate 82, swing rod 83, and guide groove 7261, the traction plate 725 drives the swing rod 83 and the swing plate 82 to move synchronously until the swing rod 83 moves to the middle section of the V-shape. At this point, the swing rod 83 is limited, causing the swing plate 82 to drive the support rod 81 to rotate 180° relative to the traction plate 725. Subsequently, the traction plate 725 drives the support rod 81 and the anti-scalding ear 77 to move towards the opening 22 to the edge of the soup plate 3.

[0072] Furthermore, in this application, the anti-scalding ear 77 is provided with a slot at the edge of the soup plate 3, and the anti-scalding ear 77 is fitted onto the edge of the soup plate 3 through the slot until the traction plate 725 stops moving.

[0073] Subsequently, the clamping plate 95 disengages from the anti-scalding ear 77 and returns to the inside of the side shell 4.

[0074] At this point, service personnel or customers can remove the soup plate 3 by pressing the anti-scalding ear 77 with their fingers to further prevent scalding.

[0075] A protective shell 78 is also fixedly installed on the outside of the side shell 4, and the drive motor 74 is installed inside the protective shell 78. The drive motor 74 is used to drive the rotating shaft 71.

[0076] One end of the drive rod 75 is located inside the side shell 4 and connected to the mating advance member 76. Multiple anti-scalding ears 77 are provided. In this application, the anti-scalding ears 77 are made of hard heat-insulating rubber material to play a role in heat insulation. The mating advance member 76 is used to sequentially advance and convey multiple anti-scalding ears 77.

[0077] The advancing component 76 includes a fixed frame 761, a conveyor roller 762, a conveyor belt 763, a push plate 764, and a synchronous advancing component 765. The fixed frame 761 is fixedly installed inside the side shell 4. There are two conveyor rollers 762. A first conveyor shaft 766 and a second conveyor shaft 767 are fixedly connected to the two conveyor rollers 762 respectively. The two conveyor rollers 762 are rotatably connected to the fixed frame 761 through the first conveyor shaft 766 and the second conveyor shaft 767 respectively. The conveyor belt 763 is driven between the two conveyor rollers 762.

[0078] Two push plates 764 are provided, and the two push plates 764 are respectively fixedly installed on the outer surface of the conveyor belt 763;

[0079] One end of the first transmission shaft 766 is fixedly connected to the drive rod 75, and the second transmission shaft 767 is connected to the synchronous advance member 765.

[0080] Meanwhile, a placement opening is provided on the side shell 4, and a closing cover is provided at the placement opening. When the anti-scalding ears 77 are placed, multiple anti-scalding ears 77 are connected in sequence, the cover is closed and then opened, and then multiple anti-scalding ears 77 are placed on the conveyor belt 763, and located between the push plate 764 and the synchronous advance member 765.

[0081] Please see Figures 13-15 The synchronous advancing component 765 includes a connecting frame 7651, an upper synchronous rod 7652, a lower synchronous rod 7653, an advancing wheel 7654, and a rotating component 10.

The advancing wheels 7654 are provided with a conveying groove 76541 for conveying the anti-scalding ear 77. The rotating part 10 is set at one end of the upper synchronous rod 7652 and the lower synchronous rod 7653.

[0083] The rotating component 10 includes a first rotating gear 101, a second rotating gear 102, and a third rotating gear 103. The first rotating gear 101 and the second rotating gear 102 are respectively fixedly sleeved on one end of the upper synchronous rod 7652 and the lower synchronous rod 7653, and the first rotating gear 101 and the second rotating gear 102 are meshed together. The second rotating gear 102 is meshed with the third rotating gear 103, and the third rotating gear 103 is fixedly sleeved on the outside of the second transmission shaft 767.

[0084] Specific implementation process: In this application, when the drive rod 75 rotates, it synchronously drives the first transmission shaft 766 to rotate. When the first transmission shaft 766 rotates, it drives the second transmission shaft 767 and the corresponding transmission roller 762 to rotate via the transmission belt 763. When the second transmission shaft 767 rotates, it drives the second transmission gear 102 to rotate via the third transmission gear 103. At the same time, the second transmission gear 102 drives the first transmission gear 101 to rotate synchronously. That is, at this time, the first transmission gear 101 and the second transmission gear 102 drive the upper synchronous rod 7652 and the lower synchronous rod 7653 to rotate in opposite directions. This causes the two advancing wheels 7654 at both ends of the upper synchronous rod 7652 and the lower synchronous rod 7653 to push the anti-scalding ear 77 through the transmission groove 76541. At the same time, in conjunction with the transmission belt 763, the anti-scalding ear 77 is transmitted along the opening 22, thereby assisting the two clamping plates 95 in clamping the anti-scalding ear 77.

[0085] Example 2

[0086] Please see Figure 7 and Figures 9-10 Embodiment 2 is a further supplementary description of Embodiment 1. Specifically, the intermittent drive component 73 is disposed on the outside of the side shell 4 and is connected to the rotating shaft 71. The other end of the intermittent drive component 73 is connected to the drive rod 75. The intermittent drive component 73 includes an intermittent block 731, an intermittent rod 732, an intermittent disk 733 and a gear transmission assembly 734. The intermittent block 731 is fixedly sleeved on the outside of the rotating shaft 71, and the intermittent rod 732 is fixedly installed on the intermittent block 731.

[0087] A central shaft is fixedly connected to the intermittent disk 733, and the central shaft is rotatably connected to one side of the side shell 4. One end of the central shaft located inside the side shell 4 is connected to the drive rod 75 through the gear transmission assembly 734. Multiple intermittent openings are provided around the intermittent disk 733 at equal intervals, and in this application, five intermittent openings are preferably provided.

[0088] Furthermore, as the rotating shaft 71 rotates, it drives the intermittent block 731 to rotate synchronously until the intermittent rod 732 contacts the intermittent opening, and then the intermittent rod 732 drives the intermittent disk 733 to rotate synchronously through the intermittent opening;

[0089] In this application, when the intermittent block 731 rotates 360° along with the rotating shaft 71, the intermittent disk 733 drives the drive rod 75 to rotate 72°.
