[0029] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 9As shown, the glass tube fuse gluing and bonding machine of this utility model includes a first frame 1, on which a glass tube feeding device, a gluing device 13, a copper cap feeding device, and a copper cap pushing device are provided; the glass tube feeding device includes a first vibrating plate 2 and a first indexing plate 9, the first vibrating plate 2 being used to feed the glass tube onto the first indexing plate 9 through a first guide pipe; the gluing device 13 is correspondingly arranged with the first indexing plate 9, and is used to apply liquid glue to both ends of the glass tube on the first indexing plate 9; the copper cap feeding device includes a second vibrating plate 3 and a second indexing plate 11, the second vibrating plate 3... The copper cap is fed onto the second indexing plate 11 via a second feeding pipe; the second indexing plate 11 is provided with a third indexing plate 26 for receiving the glass coated with adhesive on the first indexing plate 9; the copper cap pushing device is used to push the copper cap on the second indexing plate 11 to both ends of the coated glass tube on the third indexing plate 26 to form a glass tube fuse; a first conveyor belt 6 for discharging the glass tube fuse is provided below the third indexing plate 26; a second frame 7 is provided, and an oven 8 is provided on the second frame 7. A second conveyor belt 31 is provided between the inlet and outlet of the oven 8, and the second conveyor belt 31 is connected to the first conveyor belt 6. This setup involves first feeding glass tubes onto the first indexing plate 9 via the first vibrating feeder 2, and then feeding copper caps onto the second indexing plate 11 via the second vibrating feeder 3. Next, liquid adhesive is applied to both ends of the glass tubes on the first indexing plate 9 via the adhesive applicator 13. The glued glass tubes are then fed onto the third indexing plate 26. Finally, the copper caps on the second indexing plate 11 are pushed onto the glued glass tubes on the third indexing plate 26 via the copper cap pushing device to assemble a glass tube fuse. The assembled glass tube fuse is then discharged via the first conveyor belt 6 into the drying oven 8 for drying of the liquid adhesive, ensuring that the copper caps are fully and reliably fixed to the glass tubes. This secure fixing prevents the copper caps from falling off and improves the yield rate.

[0031] Furthermore, the copper cap feeding device has two sets: two second vibrating discs 3 are symmetrically located on both sides of the first vibrating disc 2, and a third indexing disc 26 is located between the two second indexing discs 11; the copper cap pushing device has two sets, and the two sets of copper cap pushing devices are symmetrically located on the outside of the two second indexing discs 11. This arrangement results in higher working efficiency, allowing two copper caps to be assembled on both ends of the glued glass tube simultaneously.

[0032] Furthermore, the adhesive application device 13 includes a first fixed base 19, a heating plate 14, a hopper 15, an application roller 17, and an application roller 18. The heating plate 14 is fixed on the first fixed base 19, and the hopper 15 is located on the heating plate 14. The hopper 15 is used to hold liquid adhesive. The application roller 17 and the application roller 18 are rotatably mounted on the first fixed base 19. The application roller 17 is used to transfer the liquid adhesive from the hopper 15 to the application roller 18. The application roller 18 is correspondingly arranged with the first indexing plate 9 and is used to apply the liquid adhesive to both ends of the glass tube on the first indexing plate 9. With this arrangement, the liquid adhesive in the hopper 15 will not solidify under the action of the heating plate 14. During adhesive application, the application roller 17 first transfers the liquid adhesive from the hopper 15 to the application roller 18, and then the application roller 18 applies the liquid adhesive to both ends of the glass tube on the first indexing plate 9.

[0033] Furthermore, both the gluing roller 17 and the coating roller 18 are located above the hopper 15, and each of the gluing roller 17 and the coating roller 18 is provided with a corresponding scraper 20. This arrangement allows excess liquid glue on the gluing roller 17 and the coating roller 18 to be scraped back into the hopper 15 for recycling, while also preventing excess liquid glue from solidifying on the gluing roller 17 and the coating roller 18.

[0034] Furthermore, a first driving device 16 is fixed on the first fixed base 19. The first driving device 16 includes a first motor 27 and a first gear 28. The first gear 28 is fixed to the output end of the first motor 27. A second gear 29 is fixed on the glue-applying wheel 17, and the second gear 29 meshes with the first gear 28. A third gear 30 is fixed on the glue-applying wheel 18, and the third gear 30 meshes with the second gear 29. With this configuration, the first motor 27 drives the first gear 28 to drive the second gear 29 and the third gear 30 to rotate synchronously, thereby driving the glue-applying wheel 17 to rotate and applying liquid glue, and driving the glue-applying wheel 18 to rotate and apply glue.

[0035] Furthermore, the outer edge of the first indexing plate 9 is provided with a plurality of first limiting grooves for limiting the glass tube. The outer side of the first indexing plate 9 is provided with an arc-shaped first limiting member 10, which is used to prevent the glass tube from coming out of the first limiting groove. The first end of the first limiting member 10 is located at the unloading end of the first guide pipe, and the second end of the first limiting member 10 is located at the loading end of the third indexing plate 26. With this configuration, the glass tube loading efficiency is high, and under the limitation of the first limiting member 10, the glass tube will not come out of the first limiting groove when the first indexing plate 9 rotates. When the first indexing plate 9 rotates to the loading end of the third indexing plate 26, the limitation of the first limiting member 10 is released, and the glass tube comes out of the first limiting groove and falls onto the third indexing plate 26 for receiving.

[0036] Furthermore, the first limiting member 10 is provided with a through hole corresponding to the glue-applying wheel 18 of the glue-applying device 13. This arrangement allows glue to be applied while the glass tube is limited by the first limiting member 10, preventing the glass tube from being knocked off during glue application.

[0037] Furthermore, the outer edge of the third indexing plate 26 is provided with multiple second limiting grooves for limiting the glass tube. An arc-shaped second limiting member 12 is provided on the outer side of the third indexing plate 26. The second limiting member 12 is used to prevent the glass tube from detaching from the second limiting groove. The first end of the second limiting member 12 is located at the unloading end of the first indexing plate 9, and the second end of the second limiting member 12 is located above the first conveyor belt 6. With this configuration, the glued glass tube will not detach from the second limiting groove when limited by the second limiting member 12. At this time, it is used to assemble a copper cap to form a glass tube fuse. When the third indexing plate 26 rotates until the glass tube fuse is above the first conveyor belt 6, the second limiting member 12 is released, and the glass tube fuse falls onto the first conveyor belt 6 to receive the unloaded material.

[0038] Furthermore, the outer edge of the second indexing plate 11 is provided with a plurality of third limiting grooves for limiting the copper caps; the copper cap pushing device includes a second fixed base 21, a cam 22, a turntable 23, a slide rod 24 and a spring 25. The cam 22 is fixed on the second fixed base 21, the turntable 23 is rotatably mounted on the second fixed base 21, the slide rod 24 is slidably mounted on the turntable 23, the first end of the slide rod 24 is correspondingly set with the cam 22, the second end of the slide rod 24 is located in the third limiting groove of the second indexing plate 11, and the spring 25 is sleeved on the slide rod 24, with the two ends of the spring 25 abutting against the turntable 23 and the slide rod 24 respectively. With this configuration, when assembling the copper cap, the rotation of the turntable 23 drives the slide rod 24 to rotate. When the first end of the slide rod 24 abuts against the cam 22, it is pushed to slide under the limit of the cam 22. The second end of the slide rod 24 pushes the copper cap located on the second indexing plate 11 to both ends of the glass tube after it has been coated with glue on the third indexing plate 26, forming a glass tube fuse. When the rotation of the turntable 23 drives the slide rod 24 to rotate beyond the cam 22, the slide rod 24 returns to its original position under the action of the spring 25.

[0039] Furthermore, the first frame 1 is equipped with a second drive device 4, which includes a second motor 40. A fourth gear 44 and a first sprocket 45 are fixed on the output shaft of the second motor 40. A first transmission shaft 41 is fixed on the first indexing plate 9, and a fifth gear 46 is fixed on the first transmission shaft 41. The fifth gear 46 meshes with the fourth gear 44. The second indexing plate 11, the third indexing plate 26, and the turntable 23 of the copper cap feeding device are all connected in series through the second transmission shaft 42, which is fixedly connected to the output shaft of the second motor 40. A third transmission shaft 43 is fixed on the first conveyor belt 6, and a second sprocket 47 is fixed on the third transmission shaft 43. The second sprocket 47 and the first sprocket 45 are connected by a toothed belt drive. With this configuration, the second motor 40 can simultaneously drive the first drive shaft 41 to rotate the first indexing plate 9, drive the second drive shaft 42 to rotate the second indexing plate 11, the third indexing plate 26 and the turntable 23 of the copper cap feeding device, and drive the third drive shaft 43 to rotate the first conveyor belt 6. In other words, one motor drives multiple drive shafts, which is highly practical.

[0040] In practical applications, the first conveyor belt 6 includes a drive wheel, multiple driven wheels, and multiple belts. The drive wheel is fixedly connected to one end of the third drive shaft 43, and the second sprocket 47 is fixedly connected to the other end of the third drive shaft 43. The drive wheel is driven by the driven wheels through belts, and the driven wheels are also driven by belts to the drive wheel of the second conveyor belt 31. This allows the second motor 40 to drive the third drive shaft 43 to rotate the first conveyor belt 6 while simultaneously driving the second conveyor belt 31 to rotate.

[0041] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims.
