[0083] The first electric screw 71 is a common structure in the prior art. After reading the disclosed content, a person skilled in the art can directly and unambiguously know how to set the first electric screw 71 without any creative work or excessive experiments.

[0084] The connecting seat 72 is generally T-shaped and is welded together from at least two plates. One end of the connecting seat 72 is connected to the first screw nut 71-1 via a bolt, and the other end of the connecting seat 72 is connected to the third plate 41 via a bolt.

[0085] The first electric lead screw 71 is actuated, and the first lead screw nut 71-1 is moved along the lead screw shaft, thereby linking the connecting seat 72, the second frame 40, the adjustable arm assembly 50 and the object container 60 to move up and down along the linear guide rail 30, thereby adjusting the position of the object container 60 so that the object container 60 is in a relatively suitable position, making it convenient to take items, reducing the labor intensity of the staff, reducing the chance of making mistakes, and improving work efficiency;

[0086] Regarding fixed reference paths:

According to input instructions, the arm-type robot delivers items along a fixed reference path. This is common knowledge, further reducing the labor intensity of workers, reducing the chance of making mistakes, and improving work efficiency. After reading the disclosed content, ordinary technicians in this field can directly and unambiguously know how to set it up without any creative work or excessive experimentation.

[0088] For example, after a customer places an order, the staff member places the order in the container 60. The arm-type robot moves along a black path on the ground according to the input command and delivers the order to the customer. The staff member takes the order out of the container 60 or the customer takes the order out of the container 60.

[0089] The working principle is as follows: the base 10 with rollers, the first frame 20 and the second frame 40 form a reliable supporting structure. When in use, an object is placed in the container 60, and the first screw part 70 links the second frame 40, the adjustable arm assembly 50 and the container 60 to move up and down along the linear guide 30. The position of the container 60 is adjusted by adjusting the adjustable arm assembly 50, so that the container 60 is in a relatively suitable position for easy access. The base 10 with rollers moves along the ground to deliver the object, thereby reducing the labor intensity of the staff, reducing the chance of making mistakes, and improving work efficiency.

The arm-type robot according to claim 1 or 5, characterized in that: The adjustable arm assembly (50) includes: two second screw rods (51) symmetrically connected to the second frame (40); two arms (52) symmetrically arranged, one arm (52) is linked by one second screw rod (51) and slides along a group of second frames (40), and the arms (52) have the spacing (50-1) between them; two third rails (53) are arranged one-to-one on the top of the arms (52); two third frames (54) are symmetrically arranged, one third frame (54) is slidably connected to one third rail (53) and is used to suspend the container (60); and two electric push rods (55) are connected one-to-one to the arms (52) and are used to link the third frame (54) to slide along the third rail (53), thereby linking the container (60) to move.

7. The arm-type robot according to claim 6, characterized in that: The arm (52) includes: a second slider (52-1) slidably connected to the second frame (40) and connected to the second screw nut (51-1) on the second screw part (51), and is linked by the second screw part (51) to slide along the second frame (40); and an extension arm (52-2), one end of which is connected to the second slider (52-1) and the other end extends in a direction away from the second slider (52-1) and is connected to the third track (53).

8. The arm-type robot according to claim 7, characterized in that: The third frame (54) includes: a third slider (54-1) sliding along the third track (53); a fourth plate (54-2) connected to the bottom of the third slider (54-1) and connected to the electric push rod (55); a fifth plate (54-3) connected to the top of the third slider (54-1); and two limit stoppers (54-4) connected to the top of the third slider (54-1) at intervals, with a limit space between the fifth plate (54-3), and the object container (60) connected to the limit space. The limit stopper (54-4) comprises: two protrusions (54-41) connected to the top of the third slider (54-1) at intervals, with the limit space between the protrusions and the fifth plate (54-3); a pin shaft (54-42) connected to the protrusions (54-41); and a stopper (54-43) connected to the pin shaft (54-42). With the pin shaft (54-42) as the rotation center, after the container (60) is inserted into the limit space, the stopper (54-43) is rotated to block the container (60).

9. The arm-type robot according to claim 8, characterized in that: The object container (60) comprises: two first wall panels (61) symmetrically arranged at intervals; two second wall panels (62) symmetrically arranged at intervals, which, after being connected to the first wall panels (61), are projected from top to bottom into a square frame structure; a grid-shaped basket (63) connected between the first wall panels (61) and the second wall panels (62); and two suspension arms (64) symmetrically arranged and connected one-to-one to the first wall panels (61) for being snapped into the limited space.

10. The arm-type robot according to claim 9, characterized in that: The first screw part (70) comprises: a first electric screw (71) connected to the first frame (20); and a connecting seat (72), one end of which is connected to the first screw nut (71-1) on the first electric screw (71) and the other end of which is connected to the second frame (40).
