Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0036] Reference Figures 1 to 3 The embodiment of the present application provides a stator winding machine, including a frame 10, a fixing device 20 provided on the frame 10 for fixing the compressor stator to be wound, a winding device (not shown in the figure) provided on the frame 10, and a stator loading and unloading device. The stator loading and unloading device includes a material taking station 30 provided on the side of the frame 10 for stator loading and unloading, a conveying mechanism 40 provided on the side of the material taking station 30 for conveying the compressor stator, a picking mechanism 50 provided on the frame 10 for picking up the stator, and a control system for controlling the coordinated operation between the above components. The conveying mechanism 40 includes a conveying device 41 and a plurality of material trays 42 for placing stators, which are arranged at intervals on the conveying device 41. The material picking station 30 includes a first lifting mechanism 31 arranged below the conveying device 41. The first lifting mechanism 31 is used to lift the material tray 42 moved to the material picking station 30 to cooperate with the picking mechanism 50 to pick up the stator in the material tray 42. The picking mechanism 50 includes a first manipulator 51 and a second manipulator 52 that move horizontally synchronously. The first manipulator 51 is used to remove the stator to be wound from the material tray 42, and the second manipulator 52 is used to place the stator after winding in the material tray 42 on the material picking station 30.

[0037] In this embodiment, a material picking station 30 is set on the conveying mechanism 40. When the material tray 42 with the stator to be wound moves to the material picking station 30, the first lifting mechanism 31 drives the material tray 42 and the stator to be wound to rise, and the first manipulator 51 of the picking mechanism 50 takes the stator to be wound away. While the first manipulator 51 places the stator to be wound, the other manipulator 52 places the stator that has been wound on the material tray 42 of the material picking station 30, and then the first lifting mechanism 31 descends. When the material tray 42 reaches the conveying mechanism 40, it moves forward driven by the conveying device 40, and the next material tray 42 arrives at the material picking work, and the above loading and unloading actions are repeated. With the above structure, material picking and unloading can be carried out almost simultaneously, which greatly improves the loading and unloading speed and improves production efficiency.

[0038] In this embodiment, the stator winding machine is a double-station winding machine, which can wind two stators at the same time. Figure 3There are two material trays 42 located on the material picking station 30, two first manipulators 51, which pick up two stators to be wound at the same time, and two second manipulators 52, which pick up two stators that have been wound at the same time. When the two first manipulators 51 and the two second manipulators 52 are performing the picking operation, they are moved in the vertical direction respectively through the second lifting mechanism 60 and the third lifting mechanism 70, and the second lifting mechanism 60 and the third lifting mechanism 70 are arranged in parallel on a horizontal moving mechanism 80, and the horizontal movement is achieved through the horizontal moving mechanism 80. Among them, the second lifting mechanism 60 is arranged close to the inner side of the frame 10, and the third lifting mechanism 70 is close to the material picking station 30, that is, the first manipulator 51 for picking up the stator to be wound is located on the inner side, and the second manipulator 52 for picking up the stator that has been wound is located on the outer side. When the first two stators on the fixing device 20 have completed winding, the second manipulator 52 outside the outside picks up the wound stators and moves outward under the movement of the horizontal moving mechanism 80. At this time, two stators to be wound have been conveyed to the material picking station 30. The second manipulator 52 and the wound stators pass over the material picking station 30 and move to the outside of the material picking station 30. The first manipulator 51 is located above the material picking station 30 to pick up the stators to be wound, and then the horizontal moving mechanism 80 returns horizontally, driving the first manipulator 51 to return to the top of the fixing device 20 to place the stators to be wound. At this time, the material picking station 30 is empty, and the second manipulator 52 is located above the material picking station 30 to place the wound stators on the material picking station 30. The first lifting mechanism 31 at the material picking station 30 descends, and the two material trays 42 carry the wound stators forward. The last two material trays 42 move forward to the material picking station 30, and the aforementioned loading and unloading actions are repeated. In this embodiment, a double workstation is adopted, and the two manipulators are placed perpendicular to the material tray 42, so that the first manipulator 51 and the second manipulator 52 can perform their respective functions and complete loading and unloading respectively without interference or waiting. Moreover, the first manipulator 51 and the second manipulator 52 are driven by the same horizontal moving mechanism 80, with a simple structure and low cost.

A second connecting plate 71 is fixed to the output end of the third lifting mechanism 70, and two second manipulators 52 are arranged at the bottom of the second connecting plate 71. The arrangement direction of the two first manipulators 51 is the same as the arrangement direction of the two material trays 42, so that the stators to be wound on the two material trays 42 can be picked up conveniently. Similarly, the arrangement direction of the two second manipulators 52 is the same as the arrangement direction of the two material trays 42, so that the wound stators can be placed on the two material trays 42 conveniently.

[0042] Specifically, the first lifting mechanism 31 includes a vertically arranged cylinder (not shown in the figure), an ejection device 32 driven by the cylinder, and a clamping structure between the ejection device 32 and the bottom of the tray 42. The tray 42 and the ejection device 32 are fixed by the clamping structure to prevent the tray 42 from being displaced during lifting.

[0043] The ejection device 32 includes at least two ejector rods 321 and a top plate 322 fixed to the top of the ejector rods 321. The clamping structure includes a clamping block 323 provided on the top of the top plate 322 and a clamping groove 324 provided at the bottom of the material tray 42 for the clamping block 323 to be clamped in. Of course, the positions of the clamping groove 324 and the clamping block 323 can also be interchanged, that is, the clamping groove 324 is provided on the top of the top plate 322, and the clamping block 323 is provided at the bottom of the material tray 42.

[0044] In this embodiment, two push rods 321 are provided at the bottom of each push plate 322 , and in order to facilitate the lifting and lowering of the push rods 321 , a mounting plate 325 is connected to the piston rod of the cylinder, and the two push rods 321 are driven to move simultaneously through the mounting plate 325 .
