[0002] The soup-pouring robot is mainly used in the aluminum alloy casting industry to automate operations such as scooping molten aluminum and pouring. However, the soup-pouring robot's arm will heat up after repeatedly approaching the molten aluminum, which can damage the bearings. In addition, the driven shaft of the soup-pouring arm will also experience bearing wear during repeated movements. Therefore, the bearings on the soup-pouring arm need to be maintained or replaced regularly. However, the existing soup-pouring arms are integrated structures, and the bearing components are usually embedded in the soup-pouring arm, making it difficult to remove the bearing components. Often, it is necessary to knock the bearing components to disassemble them. However, knocking the bearing components on the soup-pouring robot can easily damage the robot's reducer.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0023] This utility model provides a soup-dispensing arm structure and a soup-pouring robot. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0025] Please see Figures 1 to 4This utility model provides a soup-dispensing arm structure, including an arm body 1 and a bearing seat 2. One end of the arm body 1 is provided with a mounting base 3 for connecting to the robot body, and the other end of the arm body 1 is provided with a first connecting frame 4. The top of the bearing seat 2 is detachably connected to the bottom of the first connecting frame 4. The bearing seat 2 is provided with a mounting cavity 5 opening towards its top, and a bearing assembly 6 is provided in the mounting cavity 5. When the bearing assembly 6 needs to be replaced or repaired, the operator does not need to disassemble the arm body 1, but only needs to disassemble the bearing seat 2 which is external to the arm body 1. After the bearing seat 2 is removed from the first connecting frame 4, the bearing assembly 6 inside the bearing seat 2 can be replaced or repaired. By setting the arm body 1 and the bearing seat 2 as separate structures, the difficulty of disassembling and assembling the bearing assembly 6 is effectively reduced, and unnecessary damage to the soup-dispensing robot is avoided during the disassembly and assembly process.

[0026] In actual use, the arm 1 is connected to the body of the soup-pouring robot via the mounting base 3, and the geared motor on the soup-pouring robot is connected to the bearing assembly 6 via a chain or synchronous belt. The output end of the bearing assembly 6 is connected to the soup-pouring container. The soup-pouring robot drives the arm 1 to the aluminum liquid scooping station, and drives the bearing assembly 6 to rotate via the geared motor, so that the soup-pouring container performs the scooping action. Then, the soup-pouring robot drives the arm 1 to the pouring station, and drives the soup-pouring container to release the aluminum liquid via the geared motor and the bearing assembly 6, thereby completing the entire pouring action.

[0027] like Figures 1 to 4 As shown, further, a second connecting frame 7 is provided on the top of the bearing seat 2; multiple first connecting holes 41 are distributed on the edge of the first connecting frame 4, and a second connecting hole 71 is provided on the second connecting frame 7 corresponding to the position of the first connecting hole 41. The first connecting hole 41 and the second connecting hole 71 are connected by a first bolt 8. The threaded part of the first bolt 8 passes through the first connecting hole 41 from top to bottom and connects to the second connecting hole 71; the detachable connection between the bearing seat 2 and the arm body 1 is achieved by bolt locking. During disassembly, the operator uses a screwdriver to turn the first bolt 8, so that the first bolt 8 is pulled out from the second connecting hole 71 and the first connecting hole 41 in sequence, thus quickly completing the disassembly between the second connecting frame 7 and the first connecting frame 4.

[0028] In one embodiment, both the first connecting hole 41 and the second connecting hole 71 are provided with internal threads for connection with the first bolt 8.

[0029] like Figures 1 to 4As shown, in another embodiment, the second connecting frame 7 has third connecting holes 72 at its four corners, and the first connecting frame 4 has fourth connecting holes 42 at positions corresponding to the third connecting holes 72. The third connecting holes 72 and the fourth connecting holes 42 are connected by second bolts 9, with the threaded portion of the second bolt 9 passing through the third connecting hole 72 from bottom to top and connecting to the fourth connecting hole 42. This multi-connection structure design provides more options for different installation scenarios, usage requirements, or equipment layouts, increasing the flexibility of the structure. Furthermore, the combined use of multiple sets of connecting holes and bolts secures the bearing seat 2 and the arm 1 from different positions, forming a synchronous upper and lower connection structure, further enhancing the overall connection's strength and improving the structure's stability and durability.

[0030] In one embodiment, both the third connecting hole 72 and the fourth connecting hole 42 are provided with internal threads for connection with the second bolt 9.

[0031] like Figures 1 to 4 As shown, the bottom of the first connecting frame 4 is provided with at least one protrusion 43, and the top of the second connecting frame 7 is provided with a groove 73 that engages with the protrusion 43. By providing the protrusion 43 and the groove 73, the first connecting frame 4 and the second connecting frame 7 can be quickly positioned during installation, which facilitates the quick alignment of each connecting hole and reduces the installation difficulty of the first connecting frame 4 and the second connecting frame 7.

[0032] like Figures 1 to 4 As shown, the first connecting frame 4 is further provided with a fifth connecting hole 44 at the position of the protrusion 43, and the second connecting frame 7 is provided with a sixth connecting hole 74 at the position of the groove 73. The fifth connecting hole 44 and the sixth connecting hole 74 are connected by a third bolt 10. The threaded part of the third bolt 10 passes through the fifth connecting hole 44 from bottom to top and connects with the sixth connecting hole 74. The protrusion 43 is locked in the groove 73 by the third bolt 10, which effectively improves the reliability of the first connecting frame 4 and the second connecting frame 7 during assembly and improves the stability of the overall structure.

[0033] In one embodiment, both the fifth connecting hole 44 and the sixth connecting hole 74 are provided with internal threads for connection with the third bolt 10.

[0034] like Figures 1 to 4 As shown, the arm body 1 is further described as a hollow arm body 1, and the outer wall of the arm body 1 is provided with a plurality of lightweight holes 11. By setting the arm body 1 as a lightweight structure through the above structure, the load of the arm body 1 on the soup pouring robot is effectively reduced. At the same time, setting the arm body 1 as a hollow structure can provide a wiring channel for the geared motor.

[0035] like Figures 1 to 4 As shown, further, the bottom of the mounting base 3 is connected to the arm body 1 by multiple corner plates 31; by setting multiple corner plates 31, the reliability of the connection between the mounting base 3 and the arm body 1 can be improved, and the overall strength of the mounting base 3 can be improved.

[0036] like Figures 1 to 4 As shown, the bearing assembly 6 further includes a rotating shaft 61 and a sprocket drive 62. The rotating shaft 61 passes through the mounting cavity 5, and both ends of the rotating shaft 61 are rotatably connected to the bearing seat 2. The sprocket drive 62 is disposed on the shaft of the rotating shaft 61 and is located inside the mounting cavity 5. In use, the rotating shaft 61 is connected to the reduction motor via the sprocket drive 62. The reduction motor uses the sprocket drive 62 to drive the rotating shaft 61 to rotate, so that the rotating shaft 61 drives the soup container to perform the actions of scooping soup and pouring soup.

[0037] It should be noted that the sprocket drive unit 62 is an existing sprocket drive assembly, and the sprocket drive assembly is keyed to the rotating shaft 61.

[0038] like Figures 1 to 4 As shown, further, flange assemblies 63 are respectively provided on both sides of the bearing seat 2, and the two ends of the rotating shaft 61 are rotatably connected to the flange assemblies 63 respectively. The two ends of the rotating shaft 61 extend outward from the flange assemblies 63, and the extended ends of the rotating shaft 61 are provided with mounting holes 64. The rotating shaft 61 is rotated by using the flange assemblies 63, and the mounting holes 64 at the two extended ends of the rotating shaft 61 make it convenient for staff to replace the soup container.

[0039] This utility model also provides a soup-pouring robot, including the soup-scooping arm structure described above.

[0040] In summary, when replacing and repairing the bearing assembly 6, workers do not need to disassemble the arm body 1; they only need to remove the bearing seat 2, which is located outside the arm body 1. Once the bearing seat 2 is removed from the first connecting frame 4, the bearing assembly 6 inside the bearing seat 2 can be replaced or repaired. By designing the arm body 1 and the bearing seat 2 as a separate structure, the difficulty of disassembling and assembling the bearing assembly 6 is significantly reduced, and potential damage to the soup-pouring robot during disassembly and assembly is avoided.
