[0020] To more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The description is clear and complete. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them.

Therefore, it should not be construed as a limitation to the present invention.

[0021] Embodiments of the present invention are as follows Figures 1 to 4As shown in the figure, a stator assembly system includes a frame 1, on which a clamping and conveying mechanism 2 for clamping and conveying a stator semi-finished product 7, a bracket conveying mechanism 3 for conveying a stator bracket, and a screw installation mechanism 4 for installing screws between the stator semi-finished product 7 and the stator bracket are arranged. The clamping and conveying mechanism 2 is used to clamp the conveyed stator semi-finished product 7 and transport it to the location of the stator bracket. The stator semi-finished product 7 is the stator without the stator bracket installed; the bracket conveying mechanism 3 is used to transport the stator bracket to a fixed station for assembly with the stator semi-finished product 7; the screw installation mechanism 4 adopts any existing The automatic screw machine for installing screws places the stator semi-finished product 7 on the stator bracket and then transports them to the screw installation mechanism 4 through the bracket conveying mechanism 3 to install the screws for tightening; at this time, the screw installation mechanism 4 is arranged in parallel with the clamping conveying mechanism 2, and the clamping conveying mechanism 2 and the bracket conveying mechanism 3 are arranged on opposite sides of the top surface of the frame 1, that is, the clamping conveying mechanism 2 and the screw installation mechanism 4 are arranged in parallel from left to right in sequence at the rear side of the top surface of the frame 1, and the bracket conveying mechanism 3 is arranged at the front side of the top surface of the frame 1, that is, at the discharge end of the clamping conveying mechanism 2, that is, the tail end; at the same time, the bracket conveying mechanism 3 It is also arranged at a position below the tail end of the clamping and conveying mechanism 2 and passes through below the tail end of the screw installation mechanism 4, so that the bracket conveying mechanism 3 runs through the workstations where the clamping and conveying mechanism 2 and the screw installation mechanism 4 are located, which is convenient for the transportation of the stator bracket and the stator semi-finished product 7 placed on the stator bracket; the clamping and conveying mechanism 2 and the screw installation mechanism 4 are both installed on the frame 1 in an overhead manner through the installation bracket 10, so that they are spaced a certain distance from the top surface of the frame 1, which is convenient for the lifting and lowering of the clamping and conveying mechanism 2 and the screw installation mechanism 4; the clamping and conveying mechanism 2 includes a parallel plate capable of XYZ axis movement and R axis rotation The clamping jaw cylinder 20 of the clamping jaw is provided with a pressing piece 21 which is between the two clamping jaws of the clamping jaw cylinder 20 and can move up and down, that is, the clamping and conveying mechanism 2 can move and adjust its position in three axes and can rotate to adjust its angle at the same time, so that the stator semi-finished product 7 can be conveniently transported to the stator bracket, and the position of the stator semi-finished product 7 and the stator bracket to be installed can be adjusted by rotation; the pressing piece 21, on the one hand, plays a role in stabilizing the stator semi-finished product 7 when the clamping jaw cylinder 20 clamps the stator semi-finished product 7, and on the other hand, can apply pressure to press the stator semi-finished product 7 into the stator bracket to facilitate the subsequent installation of screws.In this way, the entire system first picks up the semi-finished stator 7 that is conveyed. When picking up, both the jaw cylinder 20 and the pressing member 21 move downward. The pressing member 21 first presses against the top of the semi-finished stator 7 to limit the semi-finished stator 7 to prevent it from moving and affecting the picking up. Then, the jaws of the jaw cylinder 20 clamp the semi-finished stator 7. Next, it rises and conveys the semi-finished stator 7 above the assembly station where the semi-finished stator 7 and the stator bracket are assembled. At this station, the angle of the jaw cylinder 20 is adjusted to align the positions where the semi-finished stator 7 and the stator bracket need to install screws. Then, the jaw cylinder 20 moves downward and opens the jaws to place the semi-finished stator 7 on the surface of the stator bracket. The jaw cylinder 20 disengages from the contact with the semi-finished stator 7. Finally, the semi-finished stator 7 is pressed into the stator bracket by the downward movement of the pressing member 21, and the pressing member 21 moves upward to disengage from the contact with the semi-finished stator 7. Next, they are conveyed to the screw installation station corresponding to the screw installation mechanism 4 by the bracket conveying mechanism 3, and the semi-finished stator 7 and the stator bracket are locked with screws through the screw installation mechanism 4 to complete the assembly of the semi-finished stator 7 and the stator. The whole process is automatically completed, improving the production efficiency.

[0022] Further improvements, such as Figure 1 、 Figure 3 and Figure 4As shown in the figure, for the movement of the clamping and conveying mechanism 2 on the frame 1, the clamping and conveying mechanism 2 includes a first three-axis moving mechanism 22 capable of moving in the XYZ axes, an R-axis displacement platform 23 arranged on the first three-axis moving mechanism 22 and moving in three axes through the first three-axis moving mechanism 22, and a jaw cylinder 20 arranged on the R-axis displacement platform 23 and rotating through the R-axis displacement platform 23; the first three-axis moving mechanism 22 can adopt any existing three-axis moving platform, and an installation bracket 10 is arranged at its bottom to be installed on the top surface of the frame 1, so that there is a certain distance between the first three-axis moving mechanism 22 and the top surface of the frame 1, which is convenient for clamping the semi-finished stator 7. Through this three-axis moving platform, the R-axis displacement platform 23 is moved in the three-axis directions to adjust the position, and the jaw cylinder 20 adjusts the angle through the rotation of the R-axis displacement platform 23, which is convenient for use. When in use, the first three-axis moving mechanism 22 is arranged on the frame 1 by using the installation bracket 10, and the frame 1 is arranged at the corresponding position on the production line; the jaws of the jaw cylinder 20 are parallel jaws. When clamping the semi-finished stator 7 with the parallel jaws, the jaws clamp the semi-finished stator 7 in a manner parallel to the outer side wall of the semi-finished stator 7, thus avoiding damaging the semi-finished stator 7. At this time, two lifting cylinders 230 are correspondingly arranged at the positions on the opposite sides of the R-axis displacement platform 23, and the connection line between the two lifting cylinders 230 is perpendicular to the connection line between the two jaws of the jaw cylinder 20; the pressing member 21 is a pressing plate with a flat bottom surface, and the two ends of the top surface of the pressing member 21 are correspondingly connected to the two lifting cylinders 230 and are driven to move up and down through the lifting cylinders 230; that is, the two lifting cylinders 230 and the two jaws of the jaw cylinder 20 are at the four equal division points of the rotation circumference of the R-axis displacement platform 23, which neither affects the clamping of the jaw cylinder 20 nor affects the lifting of the pressing member 21. The flat bottom surface of the pressing member 21 can apply uniform and stable pressure to the semi-finished stator 7 when it presses on the semi-finished stator 7 without damaging it. The arrangement of the R-axis displacement platform 23 on the first three-axis moving mechanism 22 is that the R-axis displacement platform 23 is installed on the first three-axis moving mechanism 22 through a support frame 24. The support frame 24 is fixedly installed on the first three-axis moving mechanism 22 and moves through it, and the R-axis displacement platform 23 is fixedly installed on the support frame 24 and rotates on the support frame 24. On the one hand, it facilitates the connection and installation between the R-axis displacement platform 23 and the first three-axis moving mechanism 22, and on the other hand, it does not cause the complication of the structures of the first three-axis moving mechanism 22 and the R-axis displacement platform 24.

[0023] For further improvement, as Figure 2 and Figure 4 shown in the figure, vision inspection mechanisms 5 are arranged on both the clamping and conveying mechanism 2 and the screw installation mechanism 4. The vision inspection mechanism 5 adopts an industrial CCD camera to detect the positions of the semi-finished stator 7 to be assembled and the stator bracket, which is convenient for processing.

[0024] Further improvements, such as Figure 1 and Figure 2 As shown in Figure 2 , the screw mounting mechanism 4 includes a second three-axis moving mechanism 40 disposed on the frame 1 and an automatic screwdriver 41 mounted on the second three-axis moving mechanism 40 and movable in three axes by the second three-axis moving mechanism 40. The second three-axis moving mechanism 40 can also be any existing three-axis moving platform, which is mounted on the frame 1 in an overhead manner through a mounting bracket 10. The automatic screwdriver 41 can then adjust its position in the three-axis directions, facilitating the installation of screws. To further improve production efficiency, a plurality of screw mounting mechanisms 4 are arranged side by side at intervals, so that the screws of multiple products can be installed and tightened at one time.

[0025] Further improvements, such as Figure 1 As shown in Figure 1 , the bracket conveying mechanism 3 is a double-speed chain conveyor line. Optical fiber sensors 6 for positioning the double-speed chain carriers are provided on the outer edge of the guide rail of the double-speed chain conveyor line. The optical fiber sensors 6 are arranged at positions corresponding to the clamping and conveying mechanism 2 and the screw mounting mechanism 4. That is, at the position of the bracket conveying mechanism 3 corresponding to the clamping and conveying mechanism 2, the optical fiber sensors 6 are used to set a working position for limiting the stop of the double-speed chain carrier to facilitate the placement of the stator semi-finished product 7 into the stator bracket. At the position corresponding to the screw mounting mechanism 4, the optical fiber sensors 6 are also used to set a working position for limiting the stop of the double-speed chain carrier to facilitate the tightening of the screws. The optical fiber sensors 6 sense the information of the double-speed chain carriers on the double-speed chain conveyor line to stop or move them. For example, two optical fiber sensors 6 are arranged in the front and back along the conveying direction of the double-speed chain conveyor line at a working position. When the front optical fiber sensor 6 senses the stator bracket on the double-speed chain carrier, the movement of the carrier is stopped, and the clamping and conveying device 2 clamps the stator semi-finished product 7 and places it on the stator bracket of the carrier. After the rear optical fiber sensor 6 senses that the stator semi-finished product has been placed on the stator bracket of the carrier, the carrier moves to transport them to the next process.

[0026] For further improvement, a feeding mechanism (not shown in the figure) for conveying the stator semi-finished product 7 to directly below the clamping and conveying mechanism 2 is provided at the head end of the clamping and conveying mechanism 2. The feeding mechanism can adopt any existing feeding mechanism for transporting stators; for example, a track-integrated electric cylinder is provided directly below the clamping and conveying mechanism 2, which includes a slide rail, a slide plate slid on the slide rail, and a rodless electric cylinder for driving the slide plate to enter or exit directly below the clamping and conveying mechanism 2. The rodless electric cylinder is integrally connected to the slide rail. During feeding, the stator semi-finished product 7 is placed on the slide plate.

[0027] Although the present utility model has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made thereto on the basis of the present utility model, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
