[0028] Understandably, referring to Figures 1 to 4 The stator winding shaping device of this utility model includes a shaping mechanism 100, a conveyor belt 200, and a gripping mechanism 300. The shaping mechanism 100 includes a base 110, a slider 120, a first driving member 130, and two shaping blocks 140. The slider 120 is slidably connected to the base 110, and the two shaping blocks 140 are respectively fixedly connected to the base 110 and the slider 120. The shaping blocks 140 are provided with a conical portion 141 protruding from them. The first driving member 130 is used to drive the slider 120. The 20 slides on the base 110 so that the two tapered portions 141 abut against the stator winding; the output end of the conveyor belt 200 is connected to the base 110, and the conveyor belt 200 is used to transport the stator winding; the gripping mechanism 300 includes a moving component 310 and a gripper 320, the gripper 320 is connected to the movable end of the moving component 310, the moving component 310 is used to drive the gripper 320 to move between the conveyor belt 200 and the shaping block 140, and the gripper 320 is used to grip the stator winding.

[0029] The slider 120 is slidably connected to the base 110. Two shaping blocks 140 are respectively arranged on the base 110 and the slider 120, and the two shaping blocks 140 are symmetrically arranged. The output end of the conveyor belt 200 is connected to the base 110. The stator winding can be driven to output through the conveyor belt 200. The gripping mechanism 300 is arranged between the shaping mechanism 100 and the conveyor belt 200. The gripper 320 is connected to the movable end of the moving component 310. The moving component 310 can drive the gripper 320 to move between the conveyor belt 200 and the shaping block 140, so that the gripper 320 can clamp the stator winding on the conveyor belt 200 and transport it to the shaping block 140, realizing automatic feeding of the stator winding. Then, the first driving component 130 drives the slider 120 to slide towards the base 110, so that the two tapered parts 141 abut against the stator winding, thereby enabling the stator winding to automatically align between the two tapered parts 141, and the two tapered parts 141 can expand the end of the stator winding, replacing manual operation and improving the efficiency and quality of shaping.

[0030] It should be noted that the stator winding includes a stator core and a winding. The winding is fixedly installed in the stator core. The ends of the winding need to be widened to facilitate the subsequent installation of the rotor. The stator winding is placed on the conveyor belt 200 and driven by the conveyor belt 200 to transport the stator winding. Then, the moving component 310 drives the gripper 320 to move above the conveyor belt 200 and clamp the stator winding. The moving component 310 then drives the gripper 320 to place the stator winding between two shaping blocks 140. Then, the first driving component 130 drives the slider 120 to move towards the base 110, so that both tapered portions 141 abut against the winding. The ends of the winding are widened by the tapered portions 141, replacing manual operation and improving production efficiency.

[0031] The first driving component 130 can be a linear cylinder, an electric actuator, a linear slide module, etc., and is not limited here.

[0032] Understandably, referring to Figure 2 and Figure 3 The forming mechanism 100 also includes an ejection assembly 150, which includes an ejector rod 151 and a spring 152. The ejector rod 151 passes through the forming block 140, and the spring 152 is arranged between the ejector rod 151 and the forming block 140. The spring 152 is used to drive the ejector rod 151 to extend out of the forming block 140 to eject the stator winding. The ejector rod 151 passes through the forming block 140 and is slidably connected to the forming block 140. One end of the spring 152 abuts against the ejector rod 151, and the other end abuts against the forming block 140. The spring 152 can drive the ejector rod 151 to extend, so that the ejector rod 151 can automatically lift the stator winding, preventing the stator winding from getting stuck on the forming block 140 and improving the smoothness of material feeding.

[0033] It should be noted that when the first driving component 130 drives the slider 120 to descend, the tapered portion 141 can extend into the winding, thereby opening the end of the winding. This makes it easy for the stator winding to get stuck on the tapered portion 141, requiring workers to pry it off, which affects the smoothness of the stator winding unloading. By setting the push rod 151 to slide on the shaping block 140, when the two tapered blocks cooperate to press the stator winding, the stator winding can press the push rod 151 into the shaping block 140 and compress the spring 152. Then, the first driving component 130 drives the slider 120 to return to its original position, so that the spring 152 can drive the push rod 151 to extend, which can lift the stator winding from the shaping block 140, preventing the stator winding from getting stuck on the tapered portion 141 and improving the smoothness of the stator winding unloading.

[0034] Specifically, refer to Figure 2 and Figure 3A buffer block 153 is provided at the end of the push rod 151, and the buffer block 153 is detachably connected to the push rod 151. The buffer block 153 is connected to the end of the push rod 151, and can separate the push rod 151 from the stator winding, preventing the push rod 151 from directly contacting the stator winding. It can absorb and disperse the impact force generated by the push rod 151 on the stator winding, avoid damage or deformation of the stator winding, and protect the quality and integrity of the stator winding.

[0035] In addition, the buffer block 153 and the push rod 151 are detachably connected, which makes it easy to disassemble and assemble the buffer block 153, improves the maintenance convenience of the push assembly 150, reduces maintenance costs, and improves reliability.

[0036] It should be noted that the buffer block 153 can be fixed to the top rod 151 by means of adhesive, fastener connection, etc., so that the buffer block 153 can be easily disassembled and installed, improving the convenience of maintenance.

[0037] Specifically, refer to Figure 2 and Figure 3 The ejector assembly 150 also includes a connecting plate 154. Multiple ejector rods 151 are provided, all fixedly connected to the connecting plate 154 and evenly spaced along the circumference of the shaping block 140. By evenly arranging multiple ejector rods 151 along the circumference of the shaping block 140, when the ejector rods 151 extend out of the shaping block 140, they can simultaneously abut against the stator winding, ensuring stable force on the stator winding, facilitating smooth ejection of the stator winding, reducing positional displacement of the stator winding, preventing end deformation of the winding, and improving the shaping quality of the stator winding.

[0038] The spring 152 can be placed between the shaping block 140 and the connecting plate 154 so that when the spring 152 drives the connecting plate 154 to move up and down, the multiple top rods 151 can move synchronously, thereby improving stability.

[0039] Understandably, referring to Figure 2 and Figure 3 The shaping block 140 has a limiting groove 142, which is arranged around the tapered portion 141. The stator winding can be accommodated in the limiting groove 142. The limiting groove 142 is arranged around the tapered portion 141. By setting the stator winding to be accommodated in the limiting groove 142, when the two tapered portions 141 cooperate to press the stator winding, the stator winding can be stably placed on the shaping block 140, reducing the positional displacement of the stator winding, facilitating the shaping of the winding, and improving the shaping quality.

[0040] Understandably, referring to Figure 1 and Figure 5A positioning block 210 is provided at the output end of the conveyor belt 200. The positioning block 210 has a positioning groove 211, which is V-shaped. The stator winding can abut against the wall of the positioning groove 211. By providing the positioning block 210 at the output end of the conveyor belt 200, the conveyor belt 200 can drive the stator winding to abut against the positioning block 210. The positioning block 210 has a V-shaped positioning groove 211, and the stator winding can abut against the side wall of the positioning groove 211, so that the stator winding can be automatically positioned in the positioning groove 211. This improves the positional accuracy of the stator winding, facilitates the gripper 320 to grip the stator winding, improves the feeding stability of the stator winding, and improves the reliability of the device.

[0041] It should be noted that the stator windings are spaced apart on the conveyor belt 200 so that when the conveyor belt 200 drives the stator windings to abut against the positioning groove 211, there is a gap between two adjacent stator windings to facilitate gripping by the gripper 320.

[0042] Understandably, referring to Figure 1 and Figure 4 The moving component 310 includes a first moving member 311 and a second moving member 312. The second moving member 312 is connected to the movable end of the first moving member 311, and the gripper 320 is connected to the movable end of the second moving member 312. The first moving member 311 is used to drive the second moving member 312 and the gripper 320 to move in the horizontal direction, and the second moving member 312 is used to drive the gripper 320 to move in the vertical direction. The gripper 320 is connected to the movable end of the second moving component 310, and the second moving component 312 is connected to the movable end of the first moving component 311. The first moving component 311 can drive the second moving component 312 and the gripper 320 to move synchronously in the horizontal direction, and the second moving component 312 can drive the gripper 320 to move in the vertical direction. Through the cooperation of the first moving component 311 and the second moving component 312, the gripper 320 can be driven to move in the vertical plane, which facilitates the transfer of the stator winding on the conveyor belt 200 to the shaping block 140, realizes the automatic feeding of the stator winding, replaces manual operation, reduces labor intensity, and improves production efficiency.

[0043] It should be noted that the first moving part 311 and the second moving part 312 can both be linear cylinders, electric actuators, linear slide modules, etc., and are not limited here.

[0044] Understandably, referring to Figure 1 and Figure 2A guide rod 111 is fixedly connected to the base 110 in the vertical direction, and the slider 120 is slidably connected to the guide rod 111. The guide rod 111 is fixedly connected to the base 110 in the vertical direction, and the slider 120 is slidably connected to the guide rod 111, so that the slider 120 can move along the axial direction of the guide rod 111, so that the slider 120 can move smoothly and steadily, so that the shaping block 140 can move stably, which facilitates the expansion of the stator winding by the tapered part 141 and improves the shaping quality.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
