[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figure 1-6This utility model provides a technical solution: a nine-axis brushless motor stator internal winding machine, including a frame assembly 6, a front operating platform 5 on one side of the front of the frame assembly 6, a Z-axis base 2 on the frame assembly 6, a wire stripping assembly 1 and a winding assembly 3 that can slide up and down on the Z-axis base 2, the winding assembly 3 being located below the wire stripping assembly 1, and a scissor assembly 4 on one side of the frame assembly 6 directly below the winding assembly 3; when winding is required, the copper wire is passed through the wire stripping assembly 1, and then the end of the copper wire is fixed on the winding assembly 3, and the winding work is carried out by the winding assembly 3. During the winding process, the enamel on the surface of the copper wire is removed by the wire stripping assembly 1, eliminating the need for separate enamel removal treatment of the copper wire surface, saving steps and improving work efficiency; after the winding is completed, the wire stripping assembly 1 and the winding assembly 3 are moved downward synchronously by the Z-axis base 2, so that the copper wire wound on the winding assembly 3 is combined with the scissor assembly 4, and then the end of the wound copper wire is cut off by the scissor assembly 4.

[0031] The wire stripping assembly 1 includes a first horizontal plate 109, a wire stripping screw motor 101 is provided below the first horizontal plate 109, a wire stripping screw 108 is provided at the output end of the wire stripping screw motor 101, a screw slider 110 is threaded onto the wire stripping screw 108, and an installation horizontal plate is fixedly connected to the screw slider 110 through a connecting block 104. Four wire stripping boxes 113 are arranged sequentially on the installation horizontal plate. By cooperating with the wire stripping screw 108 and the screw slider 110, the wire stripping boxes 113 can be adjusted to move up and down reciprocally. During the copper wire winding process, the copper wire is stripped of its enamel coating by the reciprocating wire stripping boxes 113.

[0032] The Z-axis base 2 includes a fixed plate fixedly installed on the back of the frame assembly 6. A Z-axis servo motor is provided on the top of the fixed plate. A lifting screw is provided at the output end of the Z-axis servo motor. A first nut sleeve and a second nut sleeve are threaded together from top to bottom on the lifting screw. The first nut sleeve is fixedly connected to the first horizontal plate 109. A second horizontal plate is provided on the second nut sleeve. The winding assembly is fixedly connected to the second horizontal plate. The Z-axis servo motor can drive the lifting screw to rotate. During the rotation of the lifting screw, the first horizontal plate 109 and the second horizontal plate will move up and down along the lifting screw, thereby adjusting the position of the wire stripping assembly 1 and the winding assembly 3 in the vertical opposite direction. After the winding is completed, the Z-axis base 2 drives the wire stripping assembly 1 and the winding assembly 3 to move downward synchronously, so that the copper wire wound on the winding assembly 3 is combined with the scissor assembly 4. Then, the scissor assembly 4 cuts off the end of the wound copper wire.

[0033] The fixed plate has two symmetrical vertical slide rails on its surface. The lifting screw is located between the two vertical slide rails. The stripping assembly 1 has a first slider that cooperates with the vertical slide rails on its rear side. The winding assembly 3 has a second slider that cooperates with the vertical slide rails on its rear side. The first slider cooperates with the vertical slide rails to ensure that the stripping assembly 1 can move up and down along the lifting screw. The second slider cooperates with the vertical slide rails to ensure that the winding assembly 3 can move up and down along the lifting screw.

[0034] The first horizontal plate 109 has a guide rail 102 parallel to the wire stripping screw 108 on its surface. A guide slider 105 is slidably mounted on the guide rail 102. The mounting plate and the guide slider 105 are fixedly connected. The guide slider 105 cooperates with the guide rail 102 to ensure that the mounting plate can drive the wire stripping box 113 to move up and down along the wire stripping screw 108.

[0035] Among them, a wire stripping motor 103 is provided at the center of the mounting plate surface, and the output of the wire stripping motor 103 is provided with a motor drive wheel 106; the wire stripping motor 103 drives the motor drive wheel 106 to rotate.

[0036] A wire stripping main shaft 114 is rotatably mounted at the axis of the wire stripping box 113. A driven wheel 115 is provided on the top of the wire stripping main shaft 114. The motor drive wheel 106 and the driven wheel 115 are connected by a belt 111. When the wire stripping motor 103 drives the motor drive wheel 106 to rotate, the driven wheel 115 and the wire stripping main shaft 114 are driven to rotate under the action of the belt 111. A conical wire stripping roller 120 is provided at the bottom of the wire stripping main shaft 114. When the wire stripping main shaft 114 rotates, it drives the conical wire stripping roller 120 to rotate synchronously. Then, the rotating conical wire stripping roller 120 polishes the surface of the copper wire and removes the enamel from the surface of the copper wire.

[0037] The back of the wire stripping box 113 is provided with a wire stripping back plate 112, and the top of the wire stripping back plate 112 is provided with a wire stripping top plate 121. The top of the wire stripping spindle 114 extends above the wire stripping top plate 121. A second bearing 119 is embedded on the wire stripping top plate 121, and the wire stripping spindle 114 is rotatably connected to the wire stripping top plate 121 through the second bearing 119.

[0038] The first horizontal plate 109 has a screw end cap 107 on its surface corresponding to the end of the wire stripping screw 108. The end of the wire stripping screw 108 is rotatably connected to the screw end cap 107. The top of the wire stripping spindle 114 is fitted with a shaft end cap 117 on the side below the driven wheel 115. The top of the wire stripping box 113 is inlaid with a first bearing 118. The wire stripping spindle 114 is rotatably connected to the wire stripping box 113 through the first bearing 118.

[0039] The wire stripping motor 103 is mounted upside down under the wire stripping top plate 121. Four conical wire stripping rollers 120 are vertically and centrally mounted in the wire stripping box 113. The conical wire stripping rollers 120 are coaxially fixed to the bottom end of the wire stripping main shaft 114, which passes through the first bearing 118 into the wire stripping box 113. Simultaneously, the wire stripping main shaft 114 is fixed in the second bearing 119 between the wire stripping top plates 121. The driven wheel 115 is locked at the top of the wire stripping main shaft 114, and the motor drive wheel 106 is locked on the wire stripping motor 103.

[0040] The stripping back plate 112 is connected to the connecting block 104. Its function is to use the circular motion of the lead screw to drive the lead screw slider 110 to convert into linear motion, so that the stripping assembly 1 can achieve up and down reciprocating motion under the action of the stripping lead screw motor 101 to achieve the purpose of controlling the stripping distance.

[0041] The bottom of the inner side of the wire stripping box 113 is provided with a partition 116, and the bottom of the conical wire stripping roller 120 is rotatably connected to the partition 116. During the normal wire stripping operation of the wire stripping assembly 1, copper wire enamel will inevitably fall off into the wire stripping box 113. Therefore, the partition 116 is added to reduce the space inside the box and prevent copper shavings from splashing or falling and accumulating along the wire passage hole. At the same time, a through-tube can be provided on the side of the wire stripping box 113 to be extracted by industrial vacuum equipment to ensure the cleanliness of the inside of the wire stripping box 111.

[0042] Working principle: During use, when winding is required, the copper wire first passes through the ceramic wire guide of the stripping spindle 114 of the stripping assembly 1, then through the conical stripping roller 120, then through the stripping box 113, and then extends down, passing through the winding rod of the winding assembly 3. The end of the copper wire is then fixed on the winding assembly 3, and the winding work is carried out by the winding assembly 3. During the winding process, the conical stripping roller 120, which moves up and down reciprocally, rotates continuously to polish the copper wire that has passed through the conical stripping roller 120. The conical stripping roller 120 removes the enamel coating from the surface of the copper wire, eliminating the need for separate enamel removal treatment of the copper wire surface, saving steps and improving work efficiency. After the winding is completed, the stripping assembly 1 and the winding assembly 3 move downward synchronously through the Z-axis base 2, so that the copper wire wound on the winding assembly 3 is combined with the scissor assembly 4, and then the end of the wound copper wire is cut off by the scissor assembly 4.

[0043] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
