[0002] A carbon brush erosion protection ring is a device used to prevent motor shaft current from damaging the bearings. Carbon brush erosion protection rings mainly come in carbon brush type, insulated bearing type, and carbon ring type. They effectively protect the motor from shaft current damage by conducting electricity, insulating, or dispersing current. Existing carbon brush erosion protection ring structures generally consist of a carbon brush erosion protection ring and bundles of conductive fiber material distributed and connected along the circumference of the ring.

[0003] The current production of carbon brush electro-erosion protection rings generally involves manually inserting the conductive fiber material bundle into the slot on the electro-erosion protection ring, and then locking and fixing it with bolts. The whole process is mostly manual, with low automation, slow operation speed, low efficiency, and high labor costs, which invisibly increases the production cost of carbon brush electro-erosion protection rings.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1-7 The invention relates to an automatic wire threading device for carbon brush erosion protection rings, used in the production of carbon brush erosion protection rings, specifically for threading carbon fiber filaments into the rings. This device automates the insertion of carbon fiber filaments into holes on the circumferential surface of the carbon brush erosion protection ring, achieving automated production and assembly. The device includes a machine base 1 with two feeding mechanisms 2 arranged front and rear. A belt conveyor 3 connects the two feeding mechanisms 2. Each feeding mechanism 2 has a wire threading mechanism 4 and a shearing mechanism 5 on its left side. A robot 6 is located on the left side of the belt conveyor 3, and a unloading mechanism 7 is located on the left side of the robot 6. The device comprises several components: a feeding mechanism 2 for automatically feeding carbon fiber filaments; a belt conveyor 3 for transporting unthreaded carbon brush erosion protection rings, which are then placed onto the threading mechanism 4 by a robot 6; a shearing mechanism 5 for cutting the carbon fiber filaments into segments and threading them into holes on the circumference of the carbon brush erosion protection rings; and an unloading mechanism 7 for automatically unloading the threaded carbon brush erosion protection rings, including riveting and removing waste after threading the rings and filaments. This threading device enables automated threading of carbon fiber filaments into carbon brush erosion protection rings, saving labor and effectively improving production efficiency and quality.

[0029] In this application, the threading mechanism 4 includes a rotating structure 41 and a top-threading structure 42. The rotating structure 41 drives the carbon brush erosion protection ring to rotate, stopping it at a set angle to facilitate the threading of the carbon fiber filament from the feeding mechanism 2 into the corresponding hole on the carbon brush erosion protection ring. Correspondingly, the top-threading structure 42 pushes the end of the carbon fiber filament, which has rotated to its corresponding position, completely into the hole of the carbon brush erosion protection ring. In this mechanism, the rotating structure 41 includes a servo motor 411 and a positioning seat 412. The positioning seat 412 is used for placing and positioning the carbon brush erosion protection ring. The servo motor 411 drives the positioning seat 412 to rotate, thereby driving the carbon brush erosion protection ring to rotate. In this application, the circumference of the carbon brush erosion protection ring has 24 threading holes. The servo motor 411 drives the positioning seat 412 to rotate 15° and stop once, performing one threading and one top-threading operation. The set screw structure 42 includes a third connecting plate 421, a second horizontal cylinder 422, a push block 423, and a push rod 424. The piston rod end of the second horizontal cylinder 422 points to the center of the positioning seat 412. The push block 423 is installed on the piston rod end of the second horizontal cylinder 422, and the push rod 424 is installed on the push block 423. Through the extension and retraction movement of the piston rod of the second horizontal cylinder 422, the push block 423 and the push rod 424 can be driven to move synchronously. Through the push rod 424, the end of the carbon fiber filament can be pushed into the hole on the circumferential surface of the carbon brush electro-erosion protection ring, realizing the automatic wire threading action of the carbon brush electro-erosion protection ring. A spring 425 is fitted on the push rod 424 to protect the inserted carbon fiber filament. The spring 425 provides elastic force to the push rod 424. When the resistance encountered by the carbon fiber filament when it is pushed into the hole of the carbon brush erosion protection ring is greater than the elastic force provided by the spring 425, the spring 425 will be compressed. The push rod 424 will then move in the opposite direction to the extension direction of the second horizontal cylinder 422, thereby preventing the carbon fiber filament from being bent or the carbon brush erosion protection ring from being damaged.

[0030] In one embodiment of this application, the feeding mechanism 2 includes a base plate 21. A first linear module 22 is provided below the base plate 21. The first linear module 22 can drive the base plate 21 to move horizontally left and right on the machine base 1, facilitating the feeding of carbon fiber filaments. A second linear module 23 is provided above the base plate 21, arranged front to back. A feeding plate 24 is provided above the second linear module 23. The feeding plate 24 is provided with several positioning plates 25 arranged front to back. The feeding plate 24 is used for loading carbon fiber filaments, and the positioning plates 25 are used for positioning multiple carbon fiber filaments, ensuring that multiple carbon fiber filaments are placed in an orderly manner on the feeding plate 24. It also facilitates the carbon fiber filament clamping structure 26 mounted above the feeding plate 24 to clamp the carbon fiber filaments one by one. The carbon fiber filament clamping structure 26 can insert the beginning end (i.e., the left end) of the carbon fiber filament into the hole on the circumferential surface of the carbon brush electro-erosion protection ring.

[0031] Based on the above scheme, the carbon fiber clamping structure 26 includes a third linear module 261, a first lifting cylinder 262, a first connecting plate 263, and a gripper cylinder 264. The third linear module 261 can drive the first lifting cylinder 262 to move horizontally left and right, thereby moving the carbon fiber to the left and inserting it into the hole of the carbon brush erosion protection ring. The first lifting cylinder 262 is used to drive the first connecting plate 263 and the gripper cylinder 264 to move up and down, so that the gripper cylinder 264 can clamp the carbon fiber positioned by the positioning plate 25. Then, through the horizontal left and right movement of the third linear module 261, the left end of the carbon fiber clamped by the gripper cylinder 264 is inserted into the hole on the circumferential surface of the carbon brush erosion protection ring.

[0032] Based on the above solution, this application preferably provides a guide component 27 on the base plate 21. The guide component 27 guides the carbon fiber filaments, ensuring that the carbon fiber filaments can be accurately inserted into the holes on the circumferential surface of the carbon brush erosion protection ring. The guide component 27 is located on the left side of the feeding plate 24 and is used to guide the carbon fiber filaments to move to the left. The guide component 27 includes a first horizontal cylinder 271 mounted on the left and right. The piston rod end of the first horizontal cylinder 271 is connected to a second connecting plate 272 mounted vertically. A guide tube 273 is mounted on the second connecting plate 272. The first horizontal cylinder 271 can drive the second connecting plate 272 to move left and right, thereby driving the guide tube 273 to move left and right synchronously, aligning the guide tube 273 with the holes on the circumferential surface of the carbon brush erosion protection ring, ensuring that the carbon fiber filaments can be accurately inserted into the holes on the circumferential surface of the carbon brush erosion protection ring.

[0033] In one embodiment of this application, a stop block 31 is provided at the left end of the belt conveyor 3, and a V-shaped groove is provided on the right side of the stop block 31. The stop block 31 is used to block and position the carbon brush electro-erosion protection ring that is not threaded on the belt conveyor 3, preventing the carbon brush electro-erosion protection ring from falling off the belt conveyor 3, and at the same time, it is convenient for the robot 6 to accurately clamp the carbon brush electro-erosion protection ring.

[0034] In another embodiment of this application, the shearing mechanism 5 is disposed between the threading mechanism 4 and the feeding mechanism 2. The shearing mechanism 5 includes a second lifting cylinder 51, a support plate 52, a stationary blade 53, a drive block 54, a rotating plate 55, and a moving blade 56. The support plate 52 is connected to the cylinder body of the second lifting cylinder 51, and the stationary blade 53 is connected to the support plate 52, thus fixing the position of the stationary blade 53 relative to the second lifting cylinder 51. The drive block 54 is connected to the piston rod end of the second lifting cylinder 51, the rotating plate 55 is movably connected to the drive block 54, and the moving blade 56 is fixedly connected to the rotating plate 55. A rotating shaft 57 is connected between the support plate 52 and the rotating plate 55. When the piston rod of the second lifting cylinder 51 moves up and down, it can drive the drive block 54 to move up and down synchronously, thereby pushing the rotating plate 55 to rotate around the rotating shaft 57 as the rotation center, thereby driving the moving blade 56 to rotate, so that the moving blade 56 and the stationary blade 53 perform an opening and closing action, thus realizing the shearing action of the shearing mechanism 5.

[0035] In another embodiment of this application, the unloading mechanism 7 includes a fourth linear module 71 arranged horizontally. The fourth linear module 71 is connected to a carrier 74. A riveting structure 72 is mounted above the fourth linear module 71, and a cutting structure 73 is located on the left side of the riveting structure 72. That is, the fourth linear module 71 can drive the carrier 74 to move left and right. When the robot 6 transports the wire-threaded carbon brush erosion protection ring onto the carrier 74, the fourth linear module 71 sequentially transports the wire-threaded carbon brush erosion protection ring to the workstations where the riveting structure 72 and the cutting structure 73 are located. The riveting structure 72 can rivet and fix the wire-threaded carbon brush erosion protection ring, and the cutting structure 73 can remove excess carbon fiber waste inside the riveted carbon brush erosion protection ring to ensure the quality of the assembled carbon brush erosion protection ring.

[0036] Based on the above scheme, the riveting structure 72 includes an inverted first hydraulic cylinder 721, the lower end of which is connected to a riveting die 722. The cutting structure 73 includes an inverted second hydraulic cylinder 731, the lower end of which is connected to a cutting die 732. Specifically, the first hydraulic cylinder 721 drives the riveting die 722 downwards to rivet the carbon brush electro-erosion protection ring with threaded wire on the carrier 74, thus riveting and fixing the carbon brush electro-erosion protection ring and carbon fiber filaments, ensuring the carbon fiber filaments are firmly fixed. The second hydraulic cylinder 731 drives the cutting die 732 downwards to cut off excess carbon fiber filaments inside the riveted carbon brush electro-erosion protection ring, achieving waste shearing.

[0037] Based on the above scheme, a laser marking device 75 is provided on the left side of the cutting structure 73 in this application. The laser marking device 75 is mounted above the fourth linear module 71. The laser marking device 75 can mark the assembled carbon brush electro-erosion protection ring, which facilitates the identification of the produced carbon brush electro-erosion protection ring. It can be accurately identified and tracked, which is convenient for quality control and traceability, and can also play an anti-counterfeiting role. The laser marking device 75 is connected to a manual lifting platform 76 that is vertically installed on the machine base 1, which facilitates the height adjustment of the laser marking device 75.

[0038] Based on the above scheme, a lifting assembly 77 is provided below the laser marking machine 75 to lift the carbon brush electro-erosion protection ring that has been threaded on the carrier 74, so that the robot arm can remove it from the threading device. The lifting assembly 77 is installed in the machine base 1. The lifting assembly 77 includes a third lifting cylinder 771. The upper piston rod end of the third lifting cylinder 771 is connected to a lifting plate 772. That is, the lifting plate 772 can be lifted upward by the third lifting cylinder 771, thereby lifting the carbon brush electro-erosion protection ring that has been marked at this position upward.

[0039] The assembly process of the threading device in this application is as follows: Before the device is started, carbon fiber filaments are loaded onto the feeding plate 24 of the feeding mechanism 2, and then the device is started; the belt conveyor 3 operates, conveying the unthreaded carbon brush electro-erosion protection ring to the stop block 31 position, and then the robot 6 transports the carbon brush electro-erosion protection ring on the belt conveyor 3 to the positioning seat 412 of the threading mechanism 4; the carbon fiber filament clamping structure 26 operates, and with the cooperation of the second linear module 23 and the first lifting cylinder 262, the gripper cylinder 264 clamps a carbon fiber filament, and then the third linear module 261... Under the action of the gripper cylinder 264, the carbon fiber filament held by the gripper cylinder 264 is conveyed to the left and passes through the guide tube 273 of the guide assembly 27, and then inserted into a small hole on the circumferential surface of the carbon brush electro-erosion protection ring on the positioning seat 412; the shearing mechanism 5 is activated, the second lifting cylinder 51 drives the drive block 54 to rise, and the drive block 54 drives the rotating plate 55 to rotate, realizing the closing of the moving blade 56 and the stationary blade 53, thus cutting the carbon fiber filament inserted into the small hole on the circumferential surface of the carbon brush electro-erosion protection ring; the threading mechanism 4 is activated, the rotating structure 41 rotates 15° and stops, and then the top thread structure 42... The action involves pushing the cut carbon fiber filaments into the small holes on the circumference of the carbon brush erosion protection ring until the end of the carbon fiber filament is completely pushed into the hole; repeating the above action until all the small holes on the circumference of the carbon brush erosion protection ring are pierced by carbon fiber filaments, thus completing the filament threading action of the carbon brush erosion protection ring. Then, robot 6 transports the filament-threaded carbon brush erosion protection ring to the carrier 74 of the unloading mechanism 7; the unloading mechanism 7 is activated, the fourth linear module 71 drives the carrier 74 to move below the riveting structure 72, and then the first hydraulic cylinder 721 drives the riveting die 722. The carbon brush electro-erosion protection ring is riveted. Then, the fourth linear module 71 drives the carrier 74 to the bottom of the cutting structure 73. Then, the second hydraulic cylinder 731 drives the cutting mold 732 to cut off the excess carbon fiber inside the carbon brush electro-erosion protection ring. Finally, the fourth linear module 71 drives the carrier 74 to the bottom of the laser marking machine 75. The laser marking machine 75 marks the surface of the carbon brush electro-erosion protection ring with laser. Then, the lifting component 77 lifts the marked carbon brush electro-erosion protection ring to facilitate the unloading of the carbon brush electro-erosion protection ring, thus completing the entire process of the carbon brush electro-erosion protection ring threading operation.
