[0028] Reference Figure 1The embodiment of the present application provides a winding machine 10, including a workbench 20 and a winding mechanism 40 for winding a stator, and also includes a stator feeding device arranged on the workbench 20 and located beside the winding mechanism 40.

[0029] Reference Figure 2 , Figure 3 The stator loading device includes at least one group of support components 50 (two groups are shown in the figure) placed on the workbench 20, at least one material tray 60 arranged on the support component 50, a first detection device 70 arranged on the side of the support component 50 for detecting whether there is a material tray 60 on the support component 50, a second detection device 80 arranged on the inner side of the support component 50 for detecting whether the material tray 60 is placed in place, a locking device 90 arranged on the inner side of the support component 50 and located at the bottom of the material tray 60 for locking the material tray 60, a picking mechanism 30 for picking up the stator arranged on one side of the support component 50, and a control system for controlling the coordinated operation between the above components, and a plurality of accommodating cavities 61 for placing stators to be wound are arranged on the material tray 60.

[0030] In the embodiment of the present application, a stator feeding mechanism is arranged on the workbench 20 and beside the winding mechanism 40, and there is at least one support assembly 50, and there is at least one material tray 60 on each group of support assemblies 50, that is, multiple groups of support assemblies 50 and multiple groups of material trays 60 can be arranged according to needs, and each material tray 60 has multiple accommodating cavities 61 for placing multiple stators to be wound. In this way, a large number of stators to be wound can be loaded into the stator feeding mechanism at one time, which prolongs the time of manual loading, and can realize automatic material picking and winding for a long time by a machine. Workers do not need to stay by the winding machine 10 for a long time, which liberates manpower and reduces labor costs; at the same time, the first detection device 70 and the second detection device 80 arranged on the support assembly 50 assist in the correct placement of the material tray 60 during loading, and the locking device 90 is used to lock the material tray 60 to ensure accurate and stable loading, thereby providing guarantee for the efficient winding of the winding machine 10, and the picking mechanism 30 is used to quickly and effectively pick up the stator to realize loading and unloading of the stator.

[0031] Specifically, refer to Figure 3 , Figure 4, each group of support components 50 includes two first roller components 51 arranged in parallel and spaced apart. The distance between the two first roller components 51 matches the length of the material tray 60, so that the two ends of the material tray 60 in the length direction can be placed on the two first roller components 51 respectively. Specifically, each group of first roller components 51 includes a first mounting plate 511 fixed on the workbench 20 along the front-rear direction of the workbench 20 and a plurality of first rollers 512 fixed on the side of the first mounting plate 511 at uniform intervals, each first roller 512 is fixed on the first mounting plate 511 through a first mounting shaft 513, each first mounting shaft 513 is parallel to the workbench 20, and the bottom surfaces of the two ends of the material tray 60 in the length direction are placed on the plurality of first rollers 512 of the two first roller components 51 respectively. When the worker places the material tray 60, facing the winding mechanism 40, the side close to the worker and away from the winding mechanism 40 is the front side, the side close to the winding mechanism 40 is the rear side, and the left and right sides of the worker are the left side and the right side respectively. When placing the material tray 60, both ends of the material tray 60 are placed on the first roller assembly 51 respectively, and the material tray 60 is gently pushed. The first roller 512 rotates under the action of friction force, driving the material tray 60 to move forward easily.

[0032] Reference Figures 3 to 5 Furthermore, in order to make the material tray 60 move more smoothly, a guide assembly 52 is provided above and beside at least one of the first roller assemblies 51 for guiding the sliding movement of the end of the material tray 60. In this embodiment, a guide assembly 52 is provided above both first roller assemblies 51. A set of guide assemblies 52 is shared between the adjacent first roller assemblies 51 of the two sets of support assemblies 50.

[0033] Specifically, the guide assembly 52 includes a second mounting plate 521 fixed on the workbench 20 along the front-rear direction of the workbench 20 and a plurality of second rollers 522 evenly spaced and fixed on the top surface of the second mounting plate 521. Each second roller 522 is fixed on the second mounting plate 521 through a second mounting shaft 523. Each second mounting shaft 523 is perpendicular to the workbench 20. The position of each second roller 522 is higher than that of the first roller 512. In this way, after the material tray 60 is placed on the support assembly 50, the side surface of the end of the material tray 60 abuts against the second roller 522. When the material tray 60 slides on the first roller 512, there is rolling friction between the second roller 522 on the side and the material tray 60, which also helps the movement of the material tray 60, so that the material tray 60 moves smoothly to the predetermined position.

[0034] In this embodiment, since the material tray 60 is used to feed the winding machine 10, whether there is a material tray 60 on the working platform will affect the operation of the winding machine 10. In order to better obtain the placement status of the material tray 60, a first detection device 70 is provided beside the support assembly 50. Specifically, the first detection device 70 includes a bracket 71 provided on the workbench 20 and a photoelectric switch 72 provided on the bracket 71. When a material tray 60 is placed, the photoelectric switch 72 gives a predetermined signal, and when no material tray 60 is placed, the photoelectric switch 72 gives another predetermined signal.

[0035] Reference Figure 2 A notch 62 is provided on the edge of one end of the material tray 60, and a second detection device 80 is provided on the workbench 20 and below the notch 62. The second detection device 80 is a proximity switch. The material tray 60 has a predetermined placement direction when placed and cannot be reversed front to back. When the material tray 60 is placed correctly, the notch 62 is directly opposite the proximity switch. At this time, the proximity switch sends a predetermined signal representing that the placement is correct. When the placement is incorrect, there is no notch 62 directly above the proximity switch, and the proximity switch is blocked. At this time, it sends another predetermined signal representing that the placement is incorrect to remind the worker to rearrange it. When placing the material tray 60, by setting the above-mentioned detection device, the material tray 60 can reach the predetermined position accurately and quickly, providing guarantee for the normal operation of the subsequent winding machine 10.

[0036] In this embodiment, a locking device 90 is further provided between the two first roller assemblies 51 of the support assembly 50 below the material tray 60. This is because both ends of the material tray 60 are placed on the first rollers 512. If they are not locked, the material tray 60 will be displaced when the first rollers 512 rotate, thereby causing the stator to be wound to move, which affects the picking mechanism 30 from picking up the stator at the designated position.

[0037] Specifically, refer to Figure 6 The locking device 90 includes a driving member 91 arranged along the front-back direction of the workbench 20, a locking hook 92 connected to the output shaft of the driving member 91, and a support frame 93 for the locking hook 92 to move. Specifically, the driving member is a cylinder, the locking hook 92 is in an inclined L-shape, a sliding shaft 94 is horizontally passed through the locking hook 92, and a first slide groove 931 is provided on the support frame 93 for the sliding shaft 94 to slide, and the first slide groove 931 is inclined. The output shaft of the cylinder drives the sliding shaft 94 to move in the first slide groove 931 of the support frame 93. When the material tray 60 is not placed, the sliding shaft 94 is located at the low position of the inclined first slide groove 931. At this time, the locking hook 92 is at a low position and will not interfere with the material tray 60 at the top. When the material tray 60 is placed in place, the cylinder drives the sliding shaft 94 to move to a high position, and the locking hook 92 is at a high position. The top protrudes from the end edge of the material tray 60 to lock it to prevent it from sliding outward.

[0038] Specifically, the inclined L-shaped locking hook 92 includes a bottom block 921 and a hook portion 922 connected to the bottom block 921. The bottom block 921 is connected to the output shaft of the driving member 91 through a rotating shaft 95. The sliding shaft 94 is arranged at the connection between the hook portion 922 and the bottom block 921. The support frame 93 includes a bottom plate 933 and two side plates 934 arranged on the bottom plate 933. The two side plates 934 are arranged on the second slide grooves 932. The two ends of the rotating shaft 95 are respectively placed in the two second slide grooves 932. The first slide groove 931 is two respectively located on the two side plates 934. The position of the first slide groove 931 is higher than the second slide groove 932. The inclined first slide groove 931 includes a horizontal portion 935 and an inclined portion 936 extending downward along the horizontal portion 935. When the locking hook 92 moves, the rotating shaft 95 also moves, and the two second slide grooves 932 provide movement space for the rotating shaft 95, while the two ends of the sliding shaft 94 move in the two first slide grooves 931. When in the unlocked state, the sliding shaft 94 slides to the bottom end of the inclined portion 936, and the locking hook 92 rotates around the rotating shaft 95 and moves downward; when in the locked state, the sliding shaft 94 slides to the horizontal part of the first slide groove 931, and the locking hook 92 rotates around the rotating shaft 95 in the opposite direction and moves upward to protrude from the outside of the material tray 60 to lock the material tray 60.

[0039] like Figure 2 As shown, in this embodiment, the support components 50 are arranged in two groups in parallel, and two material trays 60 are arranged on each group of support components 50. In actual implementation, the number of support components 50 and material trays 60 can also be set according to actual conditions.

[0040] Reference Figure 1 In this embodiment, the picking mechanism 30 includes a first machine 31 for picking up the stator after winding to the unloading position and a second manipulator 32 for picking up the stator to be wound to the winding position. In this embodiment, there are two first machines 31 and two second manipulators 32. The winding machine is a double-station winding machine, that is, it can wind two stators at the same time. After the winding of the two stators is completed, the control system issues an instruction, and the second manipulator 32 picks up the two stators to be wound from the material tray. Before picking up the stator to be wound, the photoelectric switch 72 of the first detection device 70 is first used to detect whether there is a material tray on the workbench. When it is confirmed that there is a material tray, the proximity switch of the second detection device 80 detects whether the material tray is placed correctly. When it is confirmed that the material tray is placed correctly and the material tray is locked, the control system issues an instruction to the first manipulator 31 to pick up the stator to be wound, and the first manipulator 31 picks up the stator to be wound and places it in the winding position.

[0041] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
