Multiple cutting structures are arranged on a supporting platform, and two cylinder ejection mechanisms are arranged at intervals below the supporting platform. The bearing capacity of the two cylinder ejection mechanisms is equal to the load gravity on the supporting platform. A lifting mechanism is also connected to the supporting platform to guide it to move up and down, and a translation mechanism is also provided on the supporting platform to drive it to move left and right.

[0006] Furthermore, the cylinder ejection mechanism also includes a pressure regulating valve connected to the first cylinder for adjusting the output force.

[0007] Furthermore, the cylinder ejection mechanism also includes a muffler connected to the first cylinder.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0034] Reference Figure 1-Figure 2 The multi-station stator winding machine provided in the embodiment of the present application includes a frame 10, a multi-station stator fixing mechanism 20 arranged on the frame 10, a multi-station winding structure for winding the stator, and a multi-station cutting structure 30 for cutting the wire ends after winding. In this embodiment, a plurality of cutting structures 30 are arranged on a support platform 40, and two cylinder ejection mechanisms 50 are arranged at intervals below the support platform 40. The bearing capacity of the two cylinder ejection mechanisms 50 is equal to the load gravity on the support platform 40. The support platform 40 is also connected to a lifting mechanism 60 to guide it to move up and down, and the support platform 40 is also provided with a translation mechanism 70 for driving it to move left and right.

[0035] In this embodiment, two cylinder ejection mechanisms 50 are symmetrically arranged below the support platform 40. The bearing capacity of the cylinder ejection mechanism 50 is equal to the load gravity. In this way, the force on the lifting mechanism 60 in the vertical direction is greatly reduced. The lifting mechanism 60 does not need to exert force in the vertical direction. Its up and down movement only plays the role of positioning and guiding, which makes the lifting mechanism 60 more durable and has a longer service life.

[0036] In this embodiment, the cylinder ejection mechanism 50 includes a first cylinder 51, a main gas source (not shown in the figure), a three-way valve (not shown in the figure), a pilot valve (not shown in the figure) and a one-way exhaust valve (not shown in the figure), wherein the first interface of the three-way valve is connected to the main gas source, the second interface of the three-way valve is connected to the exhaust conduction control port of the pilot valve, and the third interface of the three-way valve is connected to the one-way exhaust valve and the air inlet of the pilot valve in sequence and then connected to the first cylinder 51. When the first cylinder 51 is working, the main gas source inputs gas to the first cylinder 51 through the third interface, and the piston rod extends. When the piston rod is retracted, the gas is discharged through the one-way exhaust valve after conduction under the action of the pilot valve. When the main gas source stops supplying gas and there is no gas discharged into the pilot valve, the first cylinder 51 and the one-way exhaust valve are blocked, and the gas stays in the first cylinder 51 to keep the piston rod in a suspended state.

[0037] In this embodiment, the cylinder ejection mechanism 50 further includes a pressure regulating valve (not shown) connected to the first cylinder 51 for adjusting the output force. The output force of the first cylinder 51 can be better adjusted by providing the pressure regulating valve.

[0038] In order to reduce the exhaust noise when the winding machine is in use, the cylinder ejection mechanism 50 also includes a muffler connected to the first cylinder 51.

[0039] Further, by Figure 3 It can be seen that the lifting mechanism 60 is a vertically arranged second cylinder 61, the second cylinder 61 is arranged on the left, and the piston rod of the second cylinder 61 is downwardly connected to the support platform 40. The lifting mechanism 60 and the translation mechanism 70 are arranged on the support platform 40 on the left and right respectively.

[0040] Furthermore, the translation mechanism 70 is arranged on the right and rear of the support platform 40. The translation mechanism 70 includes a first servo motor 71, a gear (not shown in the figure) connected to the output shaft of the first servo motor 71, and a rack 41 arranged on the support platform 40 along the left and right direction. The gear rotates under the drive of the first servo motor 71 and meshes with the rack 41 to drive the support platform 40 to move horizontally left and right.

[0041] In this embodiment, six cutting structures 30 are provided on the support platform 40, and the lifting mechanism 60 and the translation mechanism 70 are evenly arranged on the support platform 40. That is, two cutting structures 30 are provided on the left side of the lifting mechanism 60, two cutting structures 30 are provided between the lifting mechanism 60 and the translation mechanism 70, and two cutting structures 30 are provided on the right side of the translation mechanism 70. In this way, from the overall layout, the above layout is also more stable and more balanced.

[0042] In this embodiment, refer to Figure 4The cutting structure 30 on each station includes a scissor assembly 31 for cutting the wire ends after winding, and a pinching clamp 32 for pinching the coil and the terminal on the stator. The scissor assemblies 31 on two adjacent stations are connected through a first connecting piece 33 and connected to the piston rod of a third cylinder (not shown in the figure), and the pinching clamp 32 on two adjacent stations are connected through a second connecting piece 34 and connected to the piston rod of a fourth cylinder (not shown in the figure). After the winding is completed, the wire ends need to be cut off by the scissor assembly 31 first, and then the coil on the stator and the terminal clamp are pinched together by the pinching clamp 32. Since the cutting action of each station is the same, the pinching action on each station is also the same, so the same action on the two stations is connected through a connecting piece and driven uniformly, which simplifies the structure and has low cost.

[0043] In this embodiment, the scissor assembly 31 and the pinching clamp 32 are arranged side by side, the third cylinder and the fourth cylinder are arranged side by side, the first connecting member 33 and the second connecting member 34 are parallel and arranged front and back, and the first connecting member 33 and the second connecting member 34 have different heights. The first connecting member 33 and the second connecting member 34 are arranged front and back and have different heights, so as to avoid mutual interference when performing different actions.

[0044] Reference Figure 5 , Figure 6 In this embodiment, the scissors assembly 31 includes a clamping member 311 for fixing the thread end, and a scissors 312 for cutting the clamped and fixed thread end. The clamping member 311 and the scissors 312 are fixed on a support member 313. When cutting the thread, the thread end is first clamped and fixed by the clamping member 311, so that the scissors 312 can cut the thread. Since the two actions cooperate with each other, the clamping member 311 and the scissors 312 are fixed on a support member 313 and driven by the same cylinder.

[0045] 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.
