Description

Technical Field

[0001] The present invention relates to the technical field of motor coil production, in particular to a winding device for a compressor motor stator winding. Background Art

[0002] The motor is the power source of the compressor. The stator in the motor is equipped with multiple windings. After the windings are energized, they rotate in the magnetic field. When processing the stator, the enameled wire must first be wound into a coil winding dedicated to the stator. Specifically, the coil is wound on the winding mold to the designed number of turns, and then the coil is installed on the transfer mold. The transfer mold is inserted into the stator so that the coil fits the ramp on the stator. The coil winding on the transfer mold is installed in the stator ramp. After the coil winding is installed, the transfer mold is removed.

[0003] After the existing stator winding is wound, the coil is directly transferred from the winding mold to the transfer mold. The coil is still relatively loose. Therefore, after the transfer mold is installed in the stator, the coil needs to be manually tightened, which increases manpower consumption and reduces production efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a winding device for compressor motor stator winding. Summary of the Invention

It solves the problem mentioned in the above background technology that after the existing stator winding is wound, the coil is directly transferred from the winding mold to the transfer mold, and the coil is still relatively loose.

When the wire is pressed, the coil is located in the groove of the guide wheel.

[0023] The present invention has the following beneficial effects:

[0024] 1. The stator winding of the compressor motor uses a winding device. When winding, the energy storage gear is driven to rotate by the active gear to store energy in the mainspring. After the winding is completed, the mainspring drives the energy storage gear to rotate in the opposite direction, so that the ratchet and the pawl are engaged. The transmission is further driven by the No. 2 transmission rod, the No. 3 bevel gear, the No. 4 bevel gear, the transmission gear, and the No. 2 rotating shaft to drive the No. 1 reciprocating mechanism to move. When the No. 1 reciprocating mechanism moves, the No. 1 movable rack is engaged with the flip gear to flip the arc plate downward. The coil gathered by the arc plate falls onto the transfer mold below. Due to the gathering effect of the arc plate, the originally loose coils are gathered together to prevent the coils from falling on the transfer mold and being too scattered. Therefore, after the transfer mold is subsequently installed on the stator, the operation of manually tightening the coils is avoided, thereby saving manpower and improving production efficiency.

[0025] 2. The stator winding of the compressor motor uses a winding device. After the winding coil is wound, the No. 2 transmission rod drives the No. 2 movable rack downward through the No. 2 reciprocating mechanism while rotating. The rectangular block drives the cross bar to move downward along the inclined slide groove and the straight slide groove through the engagement of the sleeve with the limit plate. While the cross bar moves downward along the inclined slide groove, the pressure rod moves to the top of the coil. When the cross bar moves downward along the straight slide groove, the pressure rod presses the coil on the arc plate and drives the arc plate to move downward. When the arc plate moves to the bottom end, the flip gear on the side of the arc plate engages with the No. 1 movable rack, and the arc plate flips 180°. During the downward movement of the arc plate, the pressure rod further presses the coil, thereby improving the retraction effect of the winding coil and increasing the practicality of the device.

[0026] 3. The winding device for the stator winding of the compressor motor has an arc plate set as a metal spring. During the downward movement of the arc plate, due to the sliding cooperation between the arc plate and the protrusion, the arc plate is continuously deformed, and the arc plate bends in the direction away from the fixed rod. The arc plate continuously stretches the coil during the bending process, thereby strengthening the tightening effect of the arc plate on the coil. In addition, the rubber strips arranged on both sides of the arc plate can effectively prevent the insulation layer of the wire from being worn when the coil is stretched, further increasing the practicality of the device.

[0041] For details, see Figure 2 、 Figure 3A flat plate 217 is provided on the side of the housing 101, on which a No. 1 rotating shaft 215 is rotatably installed. The No. 1 rotating shaft 215 is connected to the arc plate 204, and a flip gear 216 is installed at one end of the No. 1 rotating shaft 215. A No. 1 reciprocating mechanism 2100 is provided on the side of the housing 101. The No. 1 reciprocating mechanism 2100 includes a sleeve 201, which is installed on the side of the housing 101. A piston rod 202 is slidably installed in the sleeve 201. A No. 1 movable rack 235 for engaging with the flip gear 216 is installed on the top of the piston rod 202. The No. 1 movable rack 235 is set to Double rack and gear, a fixed gear 231 is rotatably installed on the side of the casing 101, and the fixed gear 231 is transmission-connected to the active roller 213. The No. 1 reciprocating mechanism 2100 also includes a No. 1 rotating rod 226, one end of the No. 1 rotating rod 226 is fixedly connected to the side of the fixed gear 231, and the other end of the No. 1 rotating rod 226 is hinged with a swing rod 233, and the other end of the swing rod 233 is rotatably installed with a moving gear 234, and the moving gear 234 is meshed with the No. 1 movable rack 235. A fixed rack 236 is also installed on the casing 101, and the fixed rack 236 is meshed with the moving gear 234.

[0042] Please refer to Figure 4 A driving gear 214 is provided on the side of the active roller 213, and the driving gear 214 is set as an incomplete gear. A bracket 218 is provided inside the casing 101, and a fixed shaft 221 is fixedly installed on the bracket 218. A rotating sleeve 220 is rotatably installed on the fixed shaft 221. A spring 222 is provided inside the rotating sleeve 220, and one end of the spring 222 is connected to the fixed shaft 221, and the other end of the spring 222 is connected to the rotating sleeve 220. An energy storage gear 219 is fixedly installed on the side of the rotating sleeve 220, and the energy storage gear 219 is transmission-connected to the fixed gear 231.

[0043] For details, see Figure 6 A No. 2 transmission rod 225 is rotatably installed on the casing 101, and a pawl 224 is hinged at one end of the No. 2 transmission rod 225. A ratchet 223 is provided inside the energy storage gear 219, and the ratchet 223 is movably engaged with the pawl 224. A No. 3 bevel gear 227 is installed at the other end of the No. 2 transmission rod 225, and a No. 2 rotating shaft 228 is rotatably installed on the outside of the casing 101. A No. 4 bevel gear 229 for meshing with the No. 3 bevel gear 227 is provided at one end of the No. 2 rotating shaft 228, and a transmission gear 230 for meshing with the fixed gear 231 is installed at the other end of the No. 2 rotating shaft 228. The transmission gear 230 drives the fixed gear 231 to rotate one circle.

[0044] It should be noted that when winding, the motor 104 drives the active roller 213 to rotate. At the same time, the active gear 214 and the energy storage gear 219 arranged on the side of the driven roller 211 are engaged, and the spring 222 on the side of the energy storage gear 219 stores energy. At this time, although the energy storage gear 219 rotates, the ratchet 223 and the pawl 224 are not engaged, so the No. 2 transmission rod 225 does not rotate. After the winding coil is wound, the active gear 214 stops rotating. At the same time, the active gear 214 loses engagement with the energy storage gear 219. The energy storage gear 219 rotates in the opposite direction under the action of the spring 222, and the pawl 224 engages with the ratchet 223, and the No. 2 transmission rod 225 rotates.

[0045] It should be noted that the specific process of the No. 1 movable rack 235 in the No. 1 reciprocating mechanism 2100 driving the arc plate 204 to flip by meshing with the flip gear 216 is as follows: when the No. 2 transmission rod 225 rotates, the No. 3 bevel gear 227, the No. 4 bevel gear 229, and the No. 2 rotating shaft 228 drive the transmission gear 230 to rotate, and the transmission gear 230 drives the fixed gear 231 to rotate. At this time, the No. 1 rotating rod 226 set on the side of the fixed gear 231 makes a circular motion, and the swing rod 233 is pulled by the No. 1 rotating rod 226. The movable rack 235 is led down to swing back and forth, and the movable gear 234 moves back and forth with the swing rod 233, further driving the No. 1 movable rack 235 to move up and down, and the No. 1 movable rack 235 is engaged with the flip gear 216 on the side of the arc plate 204, and drives the arc plate 204 to flip downward through the flip gear 216, and the No. 1 movable rack 235 completes a motion cycle, that is, the No. 1 movable rack 235 first moves upward to drive the arc plate 204 to flip, and then the No. 1 movable rack 235 moves downward to drive the arc plate 204 to reset.

[0046] In this embodiment: during winding, the motor 104 drives the active roller 213 to rotate, and through the transmission of the driven roller 211, the No. 1 transmission rod 210, the No. 1 bevel gear 209, the No. 2 bevel gear 206 and the sleeve 207, the L-shaped rod 208 drives the wire feeding head 102 to perform a circular motion around the circular plate 105. The wire in the wire feeding head 102 is wound around the fixed rod 103 and the fixed plate 106. The coil wound on the fixed rod 103 and the fixed plate 106 gradually slides onto the arc plate 204. At the same time, the active gear 214 and the energy storage gear 219 provided on the side of the driven roller 211 are engaged, and the clockwork 222 on the side of the energy storage gear 219 stores energy.

[0047] After the winding coil is wound, the energy storage gear 219 rotates in the opposite direction under the action of the mainspring 222, and the pawl 224 engages with the ratchet 223, the second transmission rod 225 rotates, and further drives the transmission gear 230 to rotate through the third bevel gear 227, the fourth bevel gear 229, and the second rotating shaft 228. The transmission gear 230 drives the fixed gear 231 to rotate. At this time, the first rotating rod 226 set on the side of the fixed gear 231 performs a circular motion, the swing rod 233 swings back and forth, and the moving gear 234 moves back and forth, further driving The No. 1 movable rack 235 moves upward, and the No. 1 movable rack 235 is engaged with the flip gear 216 on the side of the arc plate 204, and the arc plate 204 is driven to flip downward by the flip gear 216. The coils gathered by the arc plate 204 fall onto the transfer mold below. Due to the gathering effect of the arc plate 204, the originally loose coils are gathered together to prevent the coils from falling onto the transfer mold and being too dispersed. Therefore, after the transfer mold is subsequently installed on the stator, the operation of manually tightening the coils is avoided, thereby saving manpower and improving production efficiency.

[0048] Example 2: This example is intended to further solve the problem of winding and tightening the coil. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1 to 10 A slide groove 303 is provided on the outside of the casing 101, and a slider 304 is slidably installed in the slide groove 303. The flat plate 217 is fixedly installed on the side of the slider 304. A mounting plate 301 is installed on the side of the casing 101. A return spring 302 is connected between the mounting plate 301 and the slider 304. An inclined slide groove 310 and a straight slide groove 309 are opened on the side of the casing 101. The straight slide groove 309 is connected to the inclined slide groove 310. A cross bar 311 is slidably installed in the inclined slide groove 310. A pressure rod 312 is installed at one end of the cross bar 311. The cross bar 311 is transmission-connected to the energy storage gear 219. After the winding is wound, the pressure rod 312 presses the coil tightly in the arc plate 204.

[0049] In addition, see Figure 5 A second reciprocating mechanism 3100 is provided inside the casing 101. The second reciprocating mechanism 3100 is configured in the same manner as the first reciprocating mechanism 2100. The second reciprocating mechanism 3100 includes a second rotating rod 308. The second rotating rod 308 is configured in the same manner as the first rotating rod 226. The second rotating rod 308 is fixedly mounted on the second transmission rod 225. The second reciprocating mechanism 3100 also includes a second movable rack 305. The second movable rack 305 is configured in the same manner as the first movable rack 235. The second movable rack 305 is configured as a single-sided rack. A pair of limit plates 306 are installed on the side of the second movable rack 305. A rectangular block 307 is slidably installed in the pair of limit plates 306. The rectangular block 307 is fixedly connected to the cross bar 311.

[0050] The transmission gear 230 is set as an incomplete gear. When the arc plate 204 moves to the bottom end of the slide groove 303, the transmission gear 230 engages with the fixed gear 231. Specifically, when the arc plate 204 moves downward, the transmission gear 230 does not engage with the fixed gear 231, so the No. 1 reciprocating mechanism 2100 will not drive the arc plate 204 to flip over. Only when the arc plate 204 moves to the bottom end of the slide groove 303, since the transmission gear 230 engages with the fixed gear 231, the No. 1 movable rack 235 in the No. 1 reciprocating mechanism 2100 moves up and down, thereby realizing the flipping and resetting of the arc plate 204.

[0051] When the cam 314 is in the state of being rotated, the second gear 316 is engaged with the second gear 317 by the second reciprocating mechanism 3100, and the second gear 318 is engaged with the second gear 319 by the second reciprocating mechanism 311. When the cam 314 is in the state of being rotated, the second gear 316 is engaged with the second gear 317 by the second reciprocating mechanism 3100, and the second gear 318 is engaged with the second gear 319 by the second reciprocating mechanism 3100.

[0052] Example 3: This example aims to solve the problem of further tightening the coil when the coil is transferred to the transfer mold. This example is an improvement based on Example 2. For details, please refer to Figures 1 to 10 A vertical plate 401 is installed at the bottom of the circular plate 105, and a plurality of protrusions 402 are provided on the vertical plate 401. The protrusion 402 is set to a protrusion with a semicircular cross-section. The arc plate 204 is set to a metal spring. When the arc plate 204 moves downward, the arc plate 204 slides with the arc surface of the protrusion 402. A push rod 313 is installed on the side of the slider 304. The push rod 313 is located directly below the cross bar 311. When the arc plate 204 moves downward, the cross bar 311 conflicts with the push rod 313. The cross bar 311 pushes the slider 304 through the push rod 313 to prevent the pressure rod 312 from exerting a large downward pressure on the coil, causing the coil to deform.

[0053] Rubber strips 403 are installed on both sides of the arc plate 204 to prevent the wire sheath from being scratched. A pair of guide wheels 404 with grooves are set at the bottom of the pressure rod 312. When pressing the wire, the coil is located in the groove of the guide wheel 404. The guide wheel 404 guides the coil, which is conducive to the coil being retracted.

[0054] In this embodiment: during the downward movement of the arc plate 204, due to the sliding cooperation between the arc plate 204 and the protrusion 402, the arc plate 204 is continuously deformed, and the arc plate 204 bends in the direction away from the fixed rod 103. The arc plate 204 continuously stretches the coil during the bending process, thereby imitating the current manual stretching. The coil becomes more neat after being stretched by the arc plate 204, thereby enhancing the wire-organizing effect of the arc plate 204 on the coil. In addition, the rubber strips 403 arranged on both sides of the arc plate 204 can effectively prevent the insulation layer of the wire from being worn when the coil is stretched, further increasing the practicality of this device.

[0055] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
