Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, specifically to an automatic wire management and pressing assembly for a motor rotor commutator. Background Technology

[0002] In the manufacturing process of micro motors, the assembly of the rotor assembly is the core step that determines the motor's electrical performance and operational stability. The rotor assembly includes enameled wire-wound copper coils, a shaft, and a commutator. During assembly, the multiple strands of the copper coil leads need to be precisely soldered to the commutator's solder joints, such as... Figure 1 As shown.

[0003] The multiple leads of the copper coil are messy and disordered. Before the commutator is pressed in, these leads are usually pre-organized and aligned manually. Workers manually press each set of leads onto the corresponding solder points on the commutator before soldering. However, manual pressing is prone to incomplete wire organization, missing wires, and misalignment. This not only results in high labor intensity and low production efficiency but also seriously affects the yield rate of the motor. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic wire management and pressing assembly for motor rotor commutators, in order to solve the problems mentioned in the background art, such as the high labor intensity and low production efficiency of manual pressing of commutators, which are also prone to problems such as missing wires, misalignment, or incomplete wire management, which seriously affect the yield of motors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic wire management and pressing assembly for a motor rotor commutator, comprising: The mounting bracket, which is detachably mounted on the upper end of the base via a mounting plate, is used to secure the copper coil and the commutator. The cable management component is fixed to the upper end of the fixing plate and located outside the copper coil leads.

[0008] In one embodiment of the present invention, the cable management component includes a fixing ring and a driving ring. The fixing ring is fixed to the upper end of the fixing plate by a fixing screw. The fixing ring is located on the outer side of the upper end of the fixing seat. A plurality of sliding sleeves corresponding to copper coil leads are fixedly installed on the outer wall of the fixing ring. A connecting rod is slidably connected in each sliding sleeve. One end of the connecting rod is slidably inserted into the fixing ring and fixedly installed with a limiting plate. Two symmetrically arranged cable management plates are fixedly installed on the outer wall of the limiting plate.

[0009] In one embodiment of the present invention, a driving block is fixedly installed at the other end of the connecting rod, a ramp is provided at the lower end of the driving block, and a fourth spring is fixedly installed between the driving block and the fixed ring. When the fourth spring is in a balanced state, the limiting plate is attached to the inner wall of the fixed ring.

[0010] In one embodiment of the present invention, the drive ring is located below a plurality of drive blocks, and a second electric push rod is fixedly installed at the lower end of the drive ring, the lower end of the second electric push rod being fixed to the fixed plate.

[0011] In one embodiment of the present invention, a support rod is fixedly installed on one side of the upper end of the base, and a top plate is fixedly installed on the upper end of the support rod.

[0012] In one embodiment of the present invention, the pressure wire component includes a first electric push rod fixed to the lower end of the top plate. The output shaft of the first electric push rod has a cavity, and a movable tube is slidably connected in the cavity. A first spring is fixedly installed between the movable tube and the output shaft of the first electric push rod.

[0013] In one embodiment of the present invention, a conical pressure cylinder is fixedly sleeved on the outer end of the movable tube. The lower port of the pressure cylinder is larger than the upper port, and multiple elastic blocks corresponding to the lead wires are uniformly fixedly installed on the lower end of the pressure cylinder.

The shaft at the lower end of the commutator can be fixed by squeezing outward and inserting into multiple elastic plates. Copper coils and shafts of different diameters can be fixed. By setting a fixing plate on the base, installing a fixing seat and a wire management component on the fixing plate, and installing a liftable wire pressing component at the upper end of the base, the copper coil is first inserted into the fixing seat, then the commutator is inserted into the copper coil and positioned by the fixing seat. Next, the wire management component pushes the lead wire on the copper coil to the inside of the commutator. Finally, the wire pressing component presses the lead wire pushed to the commutator onto the solder joint, which can then be soldered using external soldering equipment. This improves soldering efficiency and motor yield. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 2 to 12This invention provides a technical solution: an automatic wire-reaming and pressing assembly for a motor rotor commutator, including a fixed base 30. The upper end of the fixed base 30 has an annular fixing groove 301 for inserting a copper coil 60 into the fixing groove 301 to limit its movement. The middle part of the fixed base 30 has a sliding groove 302, within which a sliding plate 303 is slidably connected. A second spring 304 is fixedly installed between the sliding plate 303 and the bottom end of the sliding groove 302. The commutator 70 is manually inserted into the copper coil 60, and the shaft at the lower end of the commutator 70 is inserted... The slide 302 is in contact with the slide plate 303 and is used to limit the commutator 70. The fixing seat 30 is detachably installed on the upper end of the base 10 via the fixing plate 40. The lower end of the fixing plate 40 is fixed to the upper end of the base 10 via the support leg 406. The support leg 406 is L-shaped, and the upper end of the support leg 406 is fixed to the lower end of the fixing plate 40. The lower end of the support leg 406 is fixed to the upper end of the base 10 by bolts, thereby stably supporting the fixing plate 40 on the upper end of the base 10. The fixing seat 30 is used to fix the copper coil 60 and the commutator 70.

[0020] The cable management component is fixed to the upper end of the fixing plate 40 and located outside the leads of the copper coil 60. The cable management component is used to push multiple sets of leads on the copper coil 60 to the welding points on the commutator 70, so that they can be welded by external welding equipment later. The wire pressing component is raised and lowered and set in the middle of the upper end of the base 10. The wire pressing component is located directly above the fixing base 30. The wire pressing component is used to press the leads pushed to the commutator 70 onto the welding points, so that the leads can be welded to the welding points of the commutator 70 later.

[0021] In one embodiment, please refer to Figure 7 - Figure 10 The cable management component includes a fixing ring 501 and a driving ring 510. The fixing ring 501 is fixed to the upper end of the fixing plate 40 by a fixing screw 502. The fixing ring 501 is located on the outer side of the upper end of the fixing base 30. When the copper coil 60 is inserted into the fixing groove 301, the fixing ring 501 is located on the outer side of the lead wire. Multiple sliding sleeves 503 corresponding to the lead wires of the copper coil 60 are fixedly installed on the outer wall of the fixing ring 501. Each sliding sleeve 503 is slidably connected to a connecting rod 504. One end of the connecting rod 504 is slidably inserted into the fixing ring 501 and fixedly installed with a limiting plate 507. Two symmetrically arranged cable management plates 508 are fixedly installed on the outer wall of the limiting plate 507. The two cable management plates 508 are arranged in an "eight" shape on the side wall of the limiting plate 507, and the end away from the limiting plate 507 has a larger opening to facilitate guiding the lead wire between the two cable management plates 508.

[0022] A drive block 505 is fixedly installed at the other end of the connecting rod 504. A ramp is provided at the lower end of the drive block 505. A fourth spring 506 is fixedly installed between the drive block 505 and the fixed ring 501. When the fourth spring 506 is in a balanced state, the limiting plate 507 is attached to the inner wall of the fixed ring 501. The drive ring 510 is located below the multiple drive blocks 505. A ramp is provided at the upper end of the drive ring 510. A second electric push rod 509 is fixedly installed at the lower end of the drive ring 510. The lower end of 09 is fixed on the fixed plate 40. When the second electric push rod 509 is started, it can push the drive ring 510 to move upward. The drive ring 510 simultaneously contacts the ramp at the lower end of multiple drive blocks 505, thereby pushing the drive blocks 505 toward one side of the fixed ring 501. The connecting rod 504 drives the limiting plate 507 and the wire management plate 508 to approach the lead wire of the copper coil 60 by squeezing the fourth spring 506. The lead wire enters into the two wire management plates 508 and pushes multiple sets of lead wires to the middle of the upper end of the commutator 70.

[0023] Before inserting the copper coil 60 into the fixing slot 301, the worker roughly straightens the multiple sets of leads of the copper coil 60 upwards. Then, the lower end of the copper coil 60 is inserted into the fixing slot 301, and the commutator 70 is inserted into the copper coil 60. The shaft at the lower end of the commutator 70 is inserted into the slide groove 302 and contacts the upper end of the slide plate 303. There is a gap between the lower end of the commutator 70 and the upper end of the copper coil 60. At the same time, the soldering point on the commutator 70 is located inside the lead. Then, the second electric push rod 509 is activated to drive the cable management plate 508 to move closer to the lead of the copper coil 60. The lead enters the two cable management plates 508 and pushes the multiple sets of leads to the middle of the upper end of the commutator 70.

[0024] In one embodiment, please refer to Figure 2 - Figure 5A support rod 101 is fixedly installed on one side of the upper end of the base 10. A top plate 102 is fixedly installed on the upper end of the support rod 101. A wire pressing component is located at the lower end of the top plate 102 to support the wire pressing component. The wire pressing component includes a first electric push rod 20 fixed at the lower end of the top plate 102. The output shaft of the first electric push rod 20 has a cavity 201. A moving tube 202 is slidably connected in the cavity 201. A first spring 203 is fixedly installed between the moving tube 202 and the output shaft of the first electric push rod 20. The moving tube 202 can slide in the output shaft of the first electric push rod 20 by squeezing the first spring 203. A conical pressure cylinder 204 is fixedly sleeved on the outer end of the moving tube 202. The lower end of the pressure cylinder 204 is larger than the upper end, and multiple elastic blocks 205 corresponding to the lead wires are evenly fixedly installed on the lower end of the pressure cylinder 204. A gap is provided between the two elastic blocks 205 to facilitate the rotation of the elastic blocks 205 inward. Both sides of the lower end of the elastic blocks 205 are rotatably connected to ball bearings 206. The outer end of the pressure cylinder 204 is fitted with a pressure ring 207. When the pressure ring 207 moves down, it contacts the elastic blocks 205 fixed at the lower end of the pressure cylinder 204 and squeezes the elastic blocks 205 inward. The lower ends of multiple elastic blocks 205 synchronously retract inward. A drive rod 208 is fixedly installed on the upper end of the pressure ring 207. The upper end of the drive rod 208 is fixed on the outer wall of the output shaft of the first electric push rod 20. A connecting rod 209 is fixedly installed on the inner end of the pressure ring 207. The end of the connecting rod 209 away from the pressure ring 207 passes through the gap between two adjacent elastic blocks 205 and is fixedly connected to an annular pressure plate 210. The drive rod 208 can synchronously drive the pressure ring 207 and the pressure plate 210 to move downward.

[0025] The first electric push rod 20 starts and drives the moving tube 202, pressure cylinder 204, and elastic block 205 to move towards one side of the fixed base 30. The lower end of the pressure cylinder 204 covers multiple sets of leads. As the pressure cylinder 204 moves downward, the lower end of the elastic block 205 first contacts the upper end of the commutator 70. The output shaft of the first electric push rod 20 continues to output by squeezing the first spring 203 and drives the drive rod 208 to continue to move downward. The drive rod 208 drives the pressure ring 207 and pressure plate 210 to move downward. When the pressure ring 207 drives the elastic block 205 to contract, the ball 206 slides on the upper end of the commutator 70. At the same time, the commutator 70 moves downward by squeezing the second spring 304, gathering multiple sets of leads inward. At the same time, the pressure plate 210 presses the gathered leads down onto the solder joints of the commutator 70. The leads can then be soldered onto the solder joints by external welding equipment. Finally, the first electric push rod 20 drives the pressure cylinder 204 to reset.

[0026] In one embodiment, please refer to Figure 3 and Figure 6A quick-release assembly is provided between the fixing plate 40 and the fixing seat 30. The quick-release assembly includes a rubber pad 401, a strip hole 402 and an elastic plate 403. The rubber pad 401 is fixed to the upper end of the fixing plate 40. The strip hole 402 is opened on the middle side wall of the fixing plate 40 and the rubber pad 401. Two elastic plates 403 are provided and symmetrically fixed to the lower middle part of the fixing seat 30. A limiting block 404 is fixedly installed on the side of the elastic plate 403 away from the fixing seat 30 and on the side away from each other. The limiting block 404 is in the shape of a right triangle. A paddle 405 is fixedly installed on the lower end of the limiting block 404.

[0027] By placing the fixing seat 30 on the upper end of the fixing plate 40, the elastic plate 403 is inserted into the strip hole 402. At the same time, the limiting block 404 passes through and is fastened to the lower end of the strip hole 402 by deforming the elastic plate 403. At this time, the lower end of the fixing seat 30 squeezes the rubber pad 401, and the rubber pad 401 applies an upward rebound force to the limiting block 404, making the limiting block 404 and the strip hole 402 more securely fastened. When the fixing seat 30 needs to be replaced, the two levers 405 are pinched and pushed inward to separate the limiting block 404 and the strip hole 402, so that the fixing seat 30 can be removed. This makes it easy to replace different fixing seats 30 to adapt to copper coils 60 and commutators 70 of different diameters.

[0028] In one embodiment, please refer to Figure 11 and Figure 12 The fixing base 30 is fixed to the upper end of the fixing plate 40. Multiple elastic plates 305 are fixedly installed on the upper end of the sliding plate 303. The multiple elastic plates 305 are combined into a round tube shape that is thinner in the middle and thicker at both ends, which facilitates the clamping of the shaft of the commutator 70. The shaft is inserted into the multiple elastic plates 305. Since the elastic plates 305 have good elasticity, they can clamp the shafts of the commutator 70 with different diameters.

[0029] The mounting base 30 has an installation cavity located inside the mounting groove 301. An airbag 306 is fixedly installed inside the mounting cavity. Multiple protective plates 308 are evenly fixedly installed on the side wall of the airbag 306. A telescopic rod 309 is fixedly installed on the side wall of the protective plate 308. The end of the telescopic rod 309 away from the protective plate 308 slides into the mounting groove 301 and is fixedly installed with a push plate 310. The push plate 310 is arc-shaped and is an elastic plate. A third spring 311 is provided between the two movable ends of the telescopic rod 309. The two movable ends of the telescopic rod 309 can slide against each other by compressing the third spring 311. When the third spring 311 is in a balanced state, the push plate 310 is attached to the inner wall of the mounting groove 301.

[0030] A connecting tube 307 is fixedly installed on one side of the airbag 306. The end of the connecting tube 307 passes through the fixing plate 40. The connecting tube 307 is fixedly connected to the external air pipe for inflating and deflating the airbag 306. By inserting the copper coil 60 into the fixing groove 301, the airbag 306 is inflated. The expansion of the airbag 306 pushes the telescopic rod 309. The telescopic rod 309 pushes the push plate 310 to move towards one side of the copper coil 60 and abuts against the inner wall of the copper coil 60 by compressing the third spring 311. Since the push plate 310 has good elasticity, it can fit against the inner wall of copper coils 60 of different diameters, thereby fixing copper coils 60 of different diameters.

[0031] When this device is in operation, the straightened and trimmed copper coil 60 is inserted into the fixing slot 301. Then, the commutator 70 is inserted into the copper coil 60, with the lower end of the commutator 70 inserted into the sliding groove 302, thus fixing the copper coil 60 and the commutator 70 in place. Next, the second electric push rod 509 is activated to drive the cable management plate 508 towards the leads of the copper coil 60. The leads enter the two cable management plates 508, thereby simultaneously pushing multiple sets of leads towards the rotating shaft at the upper end of the commutator 70. Then, the device is activated. The first electric push rod 20 drives the pressure cylinder 204 to move down and make the elastic block 205 contact the upper end of the commutator 70, thus covering multiple sets of leads. The drive rod 208 drives the pressure ring 207 and the pressure plate 210 to move down. The pressure ring 207 squeezes the elastic block 205, and the lower ends of the multiple elastic blocks 205 contract inward and gather the multiple sets of leads inward. At the same time, the pressure plate 210 presses the gathered leads down onto the solder joints of the commutator 70, so that the leads can be soldered to the solder joints by external welding equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
