[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can realize automatic assembly of the stator and the rear end cover, thereby improving assembly efficiency; (2) The stator is initially positioned by the jacking and positioning device and re-positioned by the horizontal push device, so that the subsequent grasping is more accurate. The jacking and positioning device can lift the stator, thereby facilitating the grasping of the stator grasping module; (3) The gripping assembly is divided into a stator gripping inner claw for gripping the stator and a lead clamping claw for clamping the lead wire. It can grip the stator and clamp the lead wire at the same time, which is convenient for subsequent assembly with the rear end cover.

In the initial state, the two sets of lead wire clamps are at the same height. Then one set of lead wire clamps rises under the drive of the cylinder, lifting the lead wire upward and bending it, thereby facilitating subsequent assembly. In addition, the lifting and lowering of the pressure plate driven by the cylinder plays a role in adjusting the height of the lead wire, which is convenient for subsequent clamping; (9) The stator clamp can be adjusted in height by the lifting cylinder to reduce the height difference with the rear end cover, thus facilitating subsequent assembly.

DETAILED DESCRIPTION
[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0019] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0020] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0021] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0022] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

The stator positioning and clamping module 23 presses the stator 5 into the rear end cover 6 and grabs the assembly, and drives the stator positioning and clamping module 23 through the XZ-axis linear module 21 to transfer the assembly to the assembly blanking assembly 4; the assembly blanking assembly 4 is located on one side of the lead-out wire threading assembly 3 and is used for assembly blanking.
[0024] During assembly, the stator 5 is placed on the conveyor line 11, conveyed to the positioning jacking device 12 for jacking and positioning and re-positioned by the horizontal pushing device 13, and then the stator 5 is lifted by the jacking device 12 to separate the stator 5 from the belt line 11, and then the stator grabbing module 22 is driven by the XZ axis linear module 21 to grab the stator 5 and transfer it to the stator fixing clamping mechanism 32 to fix the stator 5. The rear end cover 6 is placed on the inclined tray overturning mechanism 33, and the tray overturning mechanism 33 is tilted toward the stator. The side close to the stator 5 slides so that the lead wire 51 passes through the lead wire hole, the lead wire clamping claw assembly 34 clamps the lead wire 51 and the tray tilting mechanism 33 returns to the center and continues to slide toward the side close to the lead wire 51 so that the stator 5 is assembled into the rear end cover 6, the stator positioning and pressing module 23 presses the stator 5 into the rear end cover 6 to complete the assembly of the stator 5 and the rear end cover 6, and then the stator fixing clamping claw mechanism 32 retreats to facilitate unloading, and the assembled assembly is unloaded through the assembly unloading component 4.
[0025] In one embodiment, it further includes a guide assembly 14 installed on the first conveyor line 111, and the guide assembly 14 includes an L-shaped mounting seat 141, a stator winding guide rod 142, and a stator core guide rod 143. The stator winding guide rod 142 and the stator core guide rod 143 are both installed on the mounting seat 141. The stator winding guide rod 142 is located on the side closer to the stator 5 and is used for guiding the winding. The stator core guide rod 143 is located on the side slightly away from the stator 5 and is used for guiding the core, so that the lead wire of the stator 5 can be kept facing forward when it is conveyed on the conveyor line 1.
[0026] In one embodiment, the belt line 11 includes two belt lines with different speeds, namely a first belt line 111 and a second belt line 112. The speed of the first belt line 111 is slower than that of the second belt line 112, and the positioning jacking device 12 and the horizontal pushing device 13 are both installed on the second belt line 112. Since there are 4 grabbing positions, the corresponding positioning jacking device 12 also has 4 groups. Specifically, starting from the side close to the first belt line 111, it is divided into a first jacking positioning component, a second jacking positioning component, a third jacking positioning component and a fourth jacking positioning component. The positioning jacking device 12 includes a first jacking cylinder 121 and a jacking seat 122. Among them, the first jacking cylinder 121 and the horizontal pushing seat 122 are close to the first belt line 111. The first three groups of jacking and positioning devices 12 each have two first jacking cylinders 121, the piston rod of the lower first jacking cylinder 121 is connected to the bottom of the upper first jacking cylinder 121, and the jacking seats 22 of the first three groups close to the first belt line 111 have the same structure and include a base plate 1221 and a first jacking arm 1222 and a second jacking arm 1223 vertically mounted on both sides of the base plate 1221. The length of the first jacking arm 1222 is shorter than that of the second jacking arm 1223. A connecting rod 1224 is further provided between the first jacking arm 1222 and the second jacking arm 1223, and the upper part of the side close to the first jacking arm 1222 and the second jacking arm 1223 is a step-shaped structure;The fourth group of jacking and positioning devices 12 has only one first jacking cylinder 121, and the jacking seat 122 includes a third jacking arm 1225 and a fourth jacking arm 1226 of the same length. A connecting rod 1224 is also connected between the third jacking arm 1225 and the fourth jacking arm 1226. The upper part of the side where the third jacking arm 1225 and the fourth jacking arm 1226 are close to each other is also a step-shaped structure. Two proximity switches are installed on the second jacking arm 1223, one of which has the same height as the top of the first jacking arm 1222, and the other is The height of the proximity switch is located near the top of the second jacking arm 1223, and the first stator 5 transported from the first belt line 111 stops at the rib at the end of the second belt line 112. The second stator 5 is transported to the third jacking positioning assembly. When the proximity switch on it detects the stator 5 incoming, the first jacking cylinder 121 below works, and the second jacking arm 1223 extends from the gap between the two belts while the first jacking arm 1222 does not extend, thereby blocking the stator 5 and preventing it from continuing to move forward. The subsequent two stators 5 In this way, the conveying and positioning is carried out. After the stator jacking device 12 has been initially positioned, the stator 5 is pushed to one side by the horizontal pushing device 13 for re-positioning. Specifically, the horizontal pushing device 13 includes a first horizontal pushing device for pushing the first three groups of stators 5 and a second horizontal pushing device for pushing the fourth group of stators 5. In order to avoid interference when the stator 5 is transported on the second belt line 112, the first horizontal pushing device is driven by a lifting cylinder 133. When the stator 5 passes by, the lifting cylinder 133 lifts the first horizontal pushing device. When horizontal pushing is required, the lifting cylinder 133 is used to push the first horizontal pushing device. The lowering cylinder 133 lowers the first and second horizontal pushers. Both the first and second horizontal pushers include a horizontal pusher cylinder 131 and a horizontal pusher plate 132. The horizontal pusher plate 132 is driven by the horizontal pusher cylinder 131. Once the stator 5 is lifted and positioned by the corresponding lifting seat 122, the horizontal pusher cylinder 131 drives the horizontal pusher plate 132 to push the stator 5 to one side, repositioning it. After positioning is completed, the four sets of first lifting cylinders 121 operate to lift the stator 5 upward, freeing it from the second belt line 112, thereby facilitating subsequent capture by the stator grabbing module 22.
[0027] In one embodiment, the stator grabbing module 22 includes four groups of stator grabbing inner claws 221 and four groups of first lead wire clamps 222. The stator grabbing inner claws 221 include a grabbing cylinder 2211, a first mold core 2212, a first push rod 2213, and a first clamping claw piece 2214. The grabbing cylinder 2211 is connected to the first push rod 2213 and the end of the first push rod 2213 is a conical structure. The three first clamping claw pieces 2214 are slidably mounted on the outer peripheral wall of the first mold core 2212 and expand or contract under the drive of the first push rod 2213. When grabbing the stator 5, the grabbing cylinder 2211 drives the push rod 2213 to descend, so that the three first clamping jaws 2214 expand outward, thereby grabbing the stator 5; the first lead wire clamping jaw 222 is used to clamp the lead wire 51 on the stator 5. Specifically, the first lead wire clamping jaw 222 includes a pneumatic clamping jaw and a finger installed on the pneumatic clamping jaw. The pneumatic clamping jaw drives the two fingers to close, thereby clamping the lead wire 51. After grabbing the stator 5, the stator 5 is moved to the stator fixed clamping jaw mechanism 32 by driving the XZ-axis linear module 21.
[0028] In one embodiment, the stator fixing jaw mechanism 32 includes a stator jaw 321, a lifting adjustment seat 322, and a second lifting cylinder 323. The stator jaw 321 is slidably mounted on the linear guide rail through a jaw mounting plate 324 and slides up and down along the linear guide rail under the drive of the second lifting cylinder 323. The lifting adjustment seat 322 includes a threaded screw 3221 and a nut seat 3222. A hydraulic buffer is installed on the nut seat 3222 and the second lifting cylinder 323 is installed on the nut seat 3222. When the stator 5 is in contact with the rear end When the height difference between the upper and lower covers 6 is large, the stator clamp 321 is driven down by the second lifting cylinder 323 to reduce the height difference with the rear end cover 6 for subsequent assembly. When the rear end cover 6 reaches under the stator 5 driven by the tray tilting mechanism 33, the stator clamp 321 is released so that the stator 5 falls into the rear end cover 6, and the stator 5 is pressed into the rear end cover 6 for assembly through the stator positioning and clamping module 23. In addition, the stator fixing clamp mechanism 32 needs to retreat under the drive of the cylinder after the assembly is completed to facilitate the subsequent unloading of the assembly.
[0029] In one embodiment, the tray tilting mechanism 33 includes a tilting cylinder 331, a support hinge seat 332, a tray 333 and a limit rod 334. The tray 333 is installed on the tray base plate 336 through the support hinge seat 332. The tray 333 is provided with a support rod 337 and a tray clamp 338. The support rod 337 supports the rear end cover 6. The tray clamp 338 can clamp the rear end cover 6 to prevent it from moving on the tray 333. The tilting cylinder 331 is connected to the tray 333 through the tilting hinge seat 335. The limit rod 334 is installed on the opposite side of the tilting cylinder 331. When the tilting cylinder 331 drives the tray 333 from an inclined state to a horizontal state, the limit rod 334 presses against the tray 333 to keep the tray 333 level.
