[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A fuse marking machine includes a frame, on which a feeding device, a conveying device, a laser marking device, a unloading device, a tape feeding device, and a driving device are mounted.

The laser marking device is located between the feed end and the discharge end of the conveying device, and the unloading device is located between the discharge end of the conveying device and the feed end of the tape feeding device. The driving device is used to drive the conveying device to feed the fuses and to drive the unloading device to unload the fuses.

[0008] According to the above scheme, the conveying device includes an indexing plate rotatably mounted on the frame. The indexing plate is driven to rotate by a driving device to convey the fuse from the discharge end of the feeding device to the feed end of the tape feeding device. Multiple limiting grooves that cooperate with the fuse to limit the position are evenly distributed on the outer edge of the indexing plate.

[0009] According to the above scheme, the indexing plate includes a first indexing plate and a second indexing plate. The outer edge of the first indexing plate is provided with a first limiting groove that cooperates with and limits the rubber shell of the fuse. The outer edge of the second indexing plate is provided with a second limiting groove that cooperates with and limits the pin of the fuse. The first limiting groove and the second limiting groove are arranged vertically and vertically.

[0010] According to the above scheme, the outer side of the indexing plate is provided with two arc-shaped limiting plates, the inner walls of the two arc-shaped limiting plates are correspondingly set with the limiting groove opening of the indexing plate, and the laser marking device is set between the two arc-shaped limiting plates.

[0011] According to the above scheme, the driving device includes a stepper motor and a cam divider. The stepper motor and the cam divider are fixed side by side on the frame through a first fixing plate. A drive gear is fixed at the output end of the stepper motor, and a transmission gear is fixed at the input end of the cam divider. A transmission toothed belt is wound around the drive gear and the transmission gear. The output end of the cam divider includes an output shaft and a drive shaft. The output shaft is used to drive the indexing plate to rotate, and the drive shaft is driven to connect with the unloading device.

[0012] According to the above scheme, a second fixed plate is fixed on the cam divider, and a sleeve and a mounting base are fixed on the second fixed plate; the feeding device includes a cam, a first transmission rod, a second transmission rod, a third transmission rod, and a feeding rod; the cam is fixed on the drive shaft; the first end of the first transmission rod is correspondingly arranged with the cam, and the second end of the first transmission rod passes through the mounting base and is hinged to the first end of the second transmission rod; the first transmission rod is slidably connected to the mounting base, and a return spring is provided between the first transmission rod and the mounting base; the second end of the second transmission rod is fixedly connected to the first end of the third transmission rod, and the second end of the third transmission rod passes through the sleeve and is fixedly connected to the first end of the feeding rod; the third transmission rod is rotatably connected to the sleeve; the second end of the feeding rod is located between the discharge end of the indexing plate and the feed end of the tape feeding device.

[0027] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 6 As shown, the fuse marking machine of this utility model includes a frame 1, on which a feeding device, a conveying device, a laser marking device 6, a unloading device, a tape feeding device 7, and a driving device are provided. The discharge end of the feeding device is correspondingly arranged with the inlet end of the conveying device, and the discharge end of the conveying device is correspondingly arranged with the inlet end of the tape feeding device 7. The laser marking device 6 is located between the inlet end and the discharge end of the conveying device, and the unloading device is located between the discharge end of the conveying device and the inlet end of the tape feeding device 7. The driving device is used to drive the conveying device to convey fuses and to drive the unloading device to unload fuses. With this setup, during operation, the fuse enters the conveyor via the discharge end of the feeding device. The conveyor then transports the fuse to the laser marking device 6, where it is marked with the product specifications, resistance value, and various electrical properties onto the fuse housing using a laser. After marking, the fuse is transported to the feeding end of the tape feeding device 7 for subsequent tape feeding. This design results in a simple overall structure, low cost, and efficient marking and tape feeding processes because the marking and tape feeding processes do not interfere with each other.

[0029] Furthermore, the conveying device includes an indexing plate 5 rotatably mounted on the frame 1. The indexing plate 5 is driven to rotate by a drive device to convey fuses from the discharge end of the feeding device to the feed end of the tape feeding device 7. Multiple limiting grooves that cooperate with the fuses are evenly distributed along the outer edge of the indexing plate 5. This configuration, using the indexing plate 5 for product conveying, saves equipment space compared to a linear conveying method. Moreover, the rotation position of the indexing plate 5 can be controlled by the drive device, resulting in more precise conveying. Specifically, the drive device rotates the indexing plate 5 from the current limiting groove to the next limiting groove. That is, after the current limiting groove receives a fuse from the discharge end of the feeding device, the drive device drives the indexing plate 5 to rotate to the next limiting groove to correspond with the discharge end of the feeding device. This facilitates continuous material receiving, marking, and unloading through the rotation of the indexing plate 5, eliminating waiting time and the need for the indexing plate 5 to complete a full rotation, thereby improving the overall machine efficiency.

[0030] Furthermore, the indexing plate 5 includes a first indexing plate 51 and a second indexing plate 53. The outer edge of the first indexing plate 51 is provided with a first limiting groove 52 that engages with and limits the housing of the fuse. The outer edge of the second indexing plate 53 is provided with a second limiting groove 54 that engages with and limits the pins of the fuse. The first limiting groove 52 and the second limiting groove 54 are arranged vertically in correspondence. This arrangement ensures good limiting effect by using the first limiting groove 52 of the first indexing plate 51 to limit the housing of the fuse, and simultaneously using the second limiting groove 54 of the second indexing plate 53 to limit the pins of the fuse. This also prevents damage to the fuse during operation.

[0031] Furthermore, the outer side of the indexing plate 5 is provided with two arc-shaped limiting plates 16, the inner walls of which correspond to the openings of the limiting grooves of the indexing plate 5. The laser marking device 6 is located between the two arc-shaped limiting plates 16. This arrangement prevents the fuse from coming out of the limiting grooves during the rotation and conveying process of the indexing plate 5, thereby making the limiting effect more reliable.

[0032] Furthermore, the driving device includes a stepper motor 8 and a cam divider 9. The stepper motor 8 and the cam divider 9 are fixed side-by-side on the frame 1 via a first fixing plate 10. A drive gear 12 is fixed to the output end of the stepper motor 8, and a transmission gear 14 is fixed to the input end of the cam divider 9. A transmission toothed belt 13 is wound around the drive gear 12 and the transmission gear 14. The output end of the cam divider 9 includes an output shaft 15 and a drive shaft 17. The output shaft 15 is used to drive the indexing plate 5 to rotate, and the drive shaft 17 is driven and connected to the unloading device. With this configuration, the stepper motor 8 drives the cam divider 9 to operate, and the cam divider 9 then drives the output shaft 15 and the drive shaft 17 to operate. The output shaft 15 is used to drive the indexing plate 5 to rotate, and the drive shaft 17 is driven and connected to the unloading device. Both outputs are achieved simultaneously through the same stepper motor 8, saving on power equipment costs and installation space, and improving practicality.

[0033] Furthermore, a second fixing plate 11 is fixed on the cam divider 9, and a sleeve 23 and a mounting base 24 are fixed on the second fixing plate 11; the feeding device includes a cam 18, a first transmission rod 19, a second transmission rod 20, a third transmission rod 21, and a feeding rod 22; the cam 18 is fixed on the drive shaft 17; the first end of the first transmission rod 19 is correspondingly arranged with the cam 18, and the second end of the first transmission rod 19 passes through the mounting base 24 and is hinged to the first end of the second transmission rod 20. The first transmission rod 19 is slidably connected to the mounting base 24, and a return spring is provided between the first transmission rod 19 and the mounting base 24; the second end of the second transmission rod 20 is fixedly connected to the first end of the third transmission rod 21, and the second end of the third transmission rod 21 passes through the sleeve 23 and is fixedly connected to the first end of the feeding rod 22. The third transmission rod 21 and the sleeve 23 are rotatably connected; the second end of the feeding rod 22 is located between the discharge end of the indexing plate 5 and the feed end of the tape feeding device 7. This configuration results in better transmission performance. The drive shaft 17 drives the cam 18 to rotate. During the rotation of the cam 18, the first transmission rod 19 is driven intermittently, meaning that the first transmission rod 19 is driven to move once for every 180 degrees rotated by the cam 18. When the first transmission rod 19 moves, it drives the second transmission rod 20 to move, which in turn drives the third transmission rod 21 to move, and the third transmission rod 21 in turn drives the feeding rod 22 to move, thus pushing the marked products on the indexing plate 5 to the feeding end of the tape feeding device 7. Specifically, when the cam 1 rotates, it pushes the first transmission rod 19 to slide horizontally relative to the mounting base 24. During the sliding process, the first transmission rod 19 drives the second transmission rod 20 to rotate horizontally. During the horizontal rotation of the second transmission rod 20, it drives the third transmission rod 21 to rotate horizontally relative to the sleeve 23. During the horizontal rotation of the third transmission rod 21, it drives the feeding rod 22 to rotate horizontally, thereby pushing the marked products on the indexing plate 5 to the feeding end of the tape feeding device 7.

[0034] In practical applications, the second end of the feeding rod 22 is located between the first indexing plate 51 and the second indexing plate 53. When feeding, it pushes the rubber shell of the fuse to make the fuse come out of the limiting groove opening, and the fuse will not be damaged or deformed. A return spring is provided between the first transmission rod 19 and the mounting base 24 to facilitate the reset of the first transmission rod 19 when it is not pushed by the cam 18, so that the cam 18 can be driven to rotate 180 degrees next time. A bearing is provided in the sleeve 23 to facilitate smoother rotation of the third transmission rod 21.

[0035] It should be noted that when the drive device drives the indexing plate 5 to rotate precisely one station, it simultaneously drives the cam 18 to rotate 180 degrees. That is, the indexing plate 5 drives the fuse to receive the material, and the conveying, marking and unloading work at the same time, resulting in high work efficiency.

[0036] Furthermore, a second sensor 25 for detecting the rotational position of the cam 18 is fixed on the second fixing plate 11.

[0037] Furthermore, the feeding device includes a vibratory feeder 2 and a feeding track 3. The discharge end of the vibratory feeder 2 is connected to the feed end of the feeding track 3, and the discharge end of the feeding track 3 is correspondingly set with the limiting groove opening of the indexing plate 5. A first sensor 4 for detecting whether the fuse has arrived is provided between the feeding track 3 and the indexing plate 5. The first sensor 4 is electrically connected to the driving device. With this configuration, the fuse is discharged from the discharge end of the vibratory feeder 2 onto the feeding track 3, and then guided along the feeding track 3 to the limiting groove opening of the indexing plate 5. When the first sensor 4 detects the arrival of the fuse, the driving device starts to work, driving the indexing plate 5 to rotate precisely.

[0038] Furthermore, the feeding track 3 is inclined between the discharge end of the vibratory feeder 2 and the feed end of the indexing plate 5. The higher end of the feeding track 3 corresponds to the vibratory feeder 2, and the lower end of the feeding track 3 corresponds to the indexing plate 5. With this arrangement, the fuse is fed from the higher end of the feeding track 3 to the lower end under its own weight, resulting in better feeding efficiency.

[0039] Furthermore, the feeding track 3 has an S-shaped structure, and a guide channel 31 is formed on the feeding track 3 to cooperate with the fuse. This design, through the S-shaped feeding track 3, provides a certain buffering effect, preventing the fuse from being damaged or deformed due to excessive impact force during feeding.

[0040] 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. All of these forms are within the scope of protection of the present utility model.
