[0002] In the production of carbon brushes, adhesive application is a crucial step, and its quality directly affects the assembly quality and performance of the carbon brushes. Currently, most existing carbon brush adhesive application machines are designed with a single station or a few stations. During the adhesive application process, after one or several carbon brushes have been coated, the machine needs to be stopped for material replacement. This high frequency of material replacement leads to long downtime and severely impacts production efficiency. Summary of the Invention

[0003] In view of the problems existing in the current fully automatic carbon brush assembly and gluing machine, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a fully automatic carbon brush assembly and gluing machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A fully automatic carbon brush assembly and gluing machine includes a base plate and a placement tray. A rotating rod is rotatably mounted on one side of the upper surface of the base plate. The placement tray is fixedly sleeved on the upper end of the rotating rod. Multiple contoured grooves are formed on the upper surface of the placement tray, and carbon brushes are placed inside each of the contoured grooves. A vertical plate is fixedly mounted on the upper surface of the base plate, on the side away from the turntable. A U-shaped plate is mounted on the side of the vertical plate closer to the turntable. A material tank is fixedly sleeved on the upper end of the U-shaped plate. An automatic gluing head is connected to the outlet of the material tank. A first transmission mechanism is provided on the inner side of the vertical plate to drive the U-shaped plate to reciprocate. A second transmission mechanism is provided on the lower end of the U-shaped plate to intermittently drive the rotating rod to rotate.

[0006] Preferably, the first transmission mechanism includes a turntable and a pin. A side plate is provided on the rear side of the middle end of the U-shaped plate. One side of the side plate is fixedly connected to the vertical plate. A turntable is provided between the side plate and the U-shaped plate. A pin is eccentrically provided on the front side of the turntable. A strip-shaped opening is provided on the middle side wall of the U-shaped plate. The front end of the pin passes through the strip-shaped opening. A transmission rod is fixedly sleeved on the middle rear side of the turntable. The rear end of the transmission rod is rotatably connected to the side plate. A motor is fixedly provided on the rear side of the side plate. The output end of the motor is fixedly connected to one end of the transmission rod.

[0007] Preferably, the second transmission mechanism includes a gear and a rack. The gear is rotatably sleeved on the lower end of the rotating rod, and the rack is meshed on the front side of the gear. The front side of the rack is fixedly connected to the lower end of the U-shaped plate. A circular groove is formed in the middle of the gear, and a rotating ring is rotatably arranged inside the circular groove. The rotating ring is fixedly sleeved on the rod wall of the rotating rod. A groove is formed on one side of the rotating ring, and a pin is rotatably arranged inside the groove. A ratchet tooth is fixedly sleeved on the rod wall of the pin. A ratchet groove is formed on the inner wall of the circular groove, and the ratchet tooth meshes with the ratchet groove. A torsion spring is movably sleeved on the rod wall of the pin, and the two ends of the torsion spring are fixedly connected to the corresponding pin and the inner wall of the groove, respectively.

[0008] Preferably, the rod wall of the round pin and the side of the U-shaped plate away from the turntable are fixedly fitted with an anti-detachment ring.

[0009] Preferably, the upper and lower side walls of the vertical plate are provided with through holes, and a sliding rod is slidably disposed inside the through hole, with one end of the sliding rod being fixedly connected to the U-shaped plate.

[0010] Preferably, a damping sleeve is rotatably fitted at the bottom end of the rotating rod, and the lower end of the damping sleeve is fixedly connected to the base plate.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a motor to drive a turntable to rotate, causing a round pin to rotate around a transmission rod as an axis. During this rotation, the round pin slides within the slot, thus pushing the U-shaped plate to move back and forth, which in turn enables the automatic glue applicator head to move back and forth to apply glue.

[0012] 2. In this utility model, the reciprocating movement of the U-shaped plate drives the rack to move, which in turn drives the gear to rotate reciprocally. When the gear rotates counterclockwise, the ratchet groove presses the ratchet teeth into the groove, thus preventing the rotating ring from rotating and consequently preventing the rotating rod from rotating. At this time, the carbon brushes on the placement plate are stationary, and the automatic glue application head moves on the carbon brushes to apply glue. During the automatic glue application head reset process, the gear rotates clockwise, at which time the ratchet groove pushes the ratchet teeth to move, causing the rotating ring to drive the rotating rod to rotate, thus enabling the next carbon brush to be rotated under the automatic glue application head, thereby realizing the continuous glue application work of multiple carbon brushes.

[0017] This utility model discloses a fully automatic carbon brush assembly and gluing machine.

[0018] Reference Figure 1-3 The fully automatic carbon brush assembly and gluing machine includes a base plate 1 and a placement tray 3. A rotating rod 2 is rotatably mounted on one side of the upper surface of the base plate 1. The placement tray 3 is fixedly sleeved on the upper end of the rotating rod 2. Multiple contoured grooves are opened on the upper surface of the placement tray 3, and carbon brushes are placed inside the multiple contoured grooves. A vertical plate 4 is fixedly mounted on the upper surface of the base plate 1 on the side away from the placement tray 3. Through holes are opened on the upper and lower side walls of the vertical plate 4. A sliding rod 9 is slidably mounted inside the through holes. One end of the sliding rod 9 is fixedly connected to a U-shaped plate 5, so that the U-shaped plate 5 can slide stably. A U-shaped plate 5 is set on the side of the vertical plate 4 close to the placement tray 3. A material tank 6 is fixedly sleeved on the upper end of the U-shaped plate 5. An automatic gluing head 7 is connected to the outlet of the material tank 6. A first transmission mechanism is set on the inner side of the vertical plate 4 to drive the U-shaped plate 5 to move back and forth. A second transmission mechanism is set on the lower end of the U-shaped plate 5 to intermittently drive the rotating rod 2 to rotate.

[0019] Reference Figure 1-3The first transmission mechanism includes a turntable 12 and a pin 13. A side plate 10 is provided on the rear side of the middle end of the U-shaped plate 5. One side of the side plate 10 is fixedly connected to the vertical plate 4. A turntable 12 is provided between the side plate 10 and the U-shaped plate 5. A pin 13 is eccentrically provided on the front side of the turntable 12. A strip-shaped opening is provided on the middle side wall of the U-shaped plate 5. The front end of the pin 13 passes through the strip-shaped opening. A transmission rod 11 is fixedly sleeved on the middle rear side of the turntable 12. The rear end of the transmission rod 11 is rotatably connected to the side plate 10. A motor is fixedly provided on the rear side of the side plate 10. The output end of the motor is fixedly connected to one end of the transmission rod 11. An anti-detachment ring is fixedly sleeved on the rod wall of the pin 13 on the side of the U-shaped plate 5 away from the turntable 12 to prevent the pin 13 from slipping out of the strip-shaped opening as much as possible. A damping sleeve is rotatably sleeved on the bottom end of the rotating rod 2. The lower end of the damping sleeve is fixedly connected to the bottom plate 1 to facilitate the suspension of the rotating rod 2.

[0020] Reference Figure 1-3 The second transmission mechanism includes a gear 14 and a rack 15. The gear 14 is rotatably sleeved on the lower end of the rotating rod 2. The rack 15 is meshed on the front side of the gear 14. The front side of the rack 15 is fixedly connected to the lower end of the U-shaped plate 5. A circular groove is opened in the middle of the gear 14. A rotating ring 17 is rotatably arranged inside the circular groove. The rotating ring 17 is fixedly sleeved on the rod wall of the rotating rod 2. A groove is opened on one side of the rotating ring 17. A shaft pin 18 is rotatably arranged inside the groove. A ratchet tooth 19 is fixedly sleeved on the rod wall of the shaft pin 18. A ratchet groove 16 is opened on the inner wall of the circular groove. The ratchet tooth 19 is meshed with the ratchet groove 16. A torsion spring 8 is movably sleeved on the rod wall of the shaft pin 18. The two ends of the torsion spring 8 are fixedly connected to the corresponding shaft pin 18 and the inner wall of the groove, respectively.

[0021] In this invention, during use, the carbon brushes to be applied with adhesive are first placed one by one into the multiple contoured grooves of the placement tray 3. The contoured grooves position the carbon brushes, ensuring accurate application of adhesive. After starting the equipment, the motor on the rear side of the side plate 10 drives the transmission rod 11 to rotate, and the turntable 12 at the front end of the transmission rod 11 rotates synchronously. The round pin 13 on the front side of the turntable 12 makes a circular motion around the transmission rod 11. Since the round pin 13 passes through the slot of the U-shaped plate 5, its circular motion pushes the U-shaped plate 5 to move back and forth in the horizontal direction (the sliding rod 9 on the vertical plate 4 is fixed to the U-shaped plate 5 to ensure smooth movement without deviation). The material tank 6 at the upper end of the U-shaped plate 5 applies glue to the carbon brush plate below through the automatic glue application head 7. When the U-shaped plate 5 moves towards the placement tray 3, the automatic glue application head 7 completes the glue application action on the carbon brush plate surface. At the same time, the rack 15 at the lower end of the U-shaped plate 5 moves synchronously with it, driving the gear 14 to rotate counterclockwise. At this time, the ratchet groove 16 on the inner wall of the gear 14 contacts the ratchet tooth 19 on the rotating ring 17. The inclined surface of the ratchet groove 16 squeezes the ratchet tooth 19, causing the ratchet tooth 19 to rotate around the shaft pin 18 and compress the torsion spring 8. The ratchet tooth 19 retracts into the groove of the rotating ring 17. The rotation of the gear 14 cannot drive the rotating ring 17 and the rotating rod 2 to rotate. The placement tray 3 remains stationary, ensuring the stability of the glue application process. When the U-shaped plate 5 returns to its original position away from the placement plate 3 after applying the adhesive, the rack 15 drives the gear 14 to rotate clockwise. At this time, the vertical surface of the ratchet groove 16 contacts the ratchet tooth 19. The ratchet tooth 19 returns to its original position and is engaged in the ratchet groove 16 under the elastic force of the torsion spring 8. The gear 14 drives the rotating ring 17 to rotate synchronously through the ratchet tooth 19. The rotating ring 17 then drives the rotating rod 2 and the placement plate 3 to rotate at a certain angle, rotating the next carbon brush that has not been coated with adhesive to below the automatic adhesive application head 7. The damping sleeve at the bottom of the rotating rod 2 can increase the rotation resistance, so that the placement plate 3 can be stably suspended after intermittent rotation, avoiding deviation due to inertia. The anti-detachment ring on the round pin 13 prevents it from slipping out of the strip opening, ensuring transmission stability. After all the carbon brushes on the placement plate 3 have been coated with glue, stop the machine and remove the finished product. Then put the carbon brushes to be processed back in and continue the operation. This device uses a first transmission mechanism to automatically apply adhesive, and a second transmission mechanism to intermittently feed the placement tray. The two work together to continuously apply adhesive to multiple carbon brushes, significantly reducing downtime for material changes and greatly improving production efficiency. The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
