1. Technical Field
The present disclosure relates to cable peeling and cutting devices, and particularly to a cable peeling and cutting device for automatically peeling and cutting a cable having a cover layer and a fiber.
2. Description of Related Art
Devices for automatically peeling and cutting cables may use a screw rod to drive a cutter to peel or cut cables. However, the screw rod drives the cutter relatively slowly. Thus, it costs a large amount of time to peel or cut the cables. In addition, the screw rod may be damaged easily after cutting and peeling a large number of cables.
Therefore, there is room for improvement in the art.

It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The mounting plate 10 comprises a top surface 11 and a bottom surface 13. The mounting plate 10 defines a slot 15 through the top surface 11 and the bottom surface 13. The first peeling member 30 and the second peeling member 50 are movably mounted on the top surface 11 of the mounting plate 10. The first peeling member 30 and the second peeling member 50 are located at opposite sides of the slot 15. The first peeling member 30 and the second peeling member 50 are movable towards or away from each other by drivers (not shown in figures). The first peeling member 30 defines a first holding hole 31 for receiving the cable holding member 300. The second peeling member 50 defines a second holding hole 51 for receiving the cable 200. The first holding hole 31 is aligned with the second holding hole 51, and an imaginary line connecting the first holding hole 31 and the second holding hole 51 is substantially parallel to the top surface 11 of the mounting plate 10.
The cutting mechanism 70 comprises a driver 71, four movable members 72, a first connecting rod 73, a second connecting rod 74, a first connecting member 75, a second connecting member 76, a sliding assembly 77, and a cutting assembly 78. The driver 71 is mounted to the bottom surface 13 of the mounting plate 10. A movable member 72 is connected to each end of the first connecting rod 73 and each end of the second connecting rod 74, respectively. One end of the first connecting rod 73 and one end of the second connecting rod 74 are connected to the driver 71 by the corresponding movable members 72, respectively. The other end of the first connecting rod 73 is connected to the first connecting member 75 by one corresponding movable member 72, and the other end of the second connecting rod 74 is connected to the second connecting member 76 by another corresponding movable member 72. The first connecting member 75 and the second connecting member 76 are received through the slot 15. The sliding assembly 77 is mounted on the top surface 11 of the mounting plate 10. The first connecting member 75 and the second connecting member 76 are vertically slidably connected to the sliding assembly 77. The cutting assembly 78 is mounted to the first connecting member 75 and the second connecting member 76, and positioned above the mounting plate 10 for cutting the cover layer 201 and the fiber of the cable 200.
The driver 71 comprises a driving body 711 and a driving end 713 connected to the driving body 711. The driving body 711 is mounted to the bottom surface 13 of the mounting plate 10 and located adjacent to the slot 15. The driving end 713 is located adjacent to an end of the slot 15. The driving body 711 rotates the driving end 713.
Each movable member 72 comprises a fixing portion 721 and a movable portion 723 rotatably sleeved around the fixing portion 721. The movable portion 723 defines a substantially spherical receiving groove 7231 according or corresponding to a shape of the fixing portion 721. The fixing portion 721 is substantially spherical and movably received in the receiving groove 7231. One fixing portion 721 connected to the first connecting rod 73 and one fixing portion 721 connected to the second connecting rod 74 are mounted to the driving end 713 substantially symmetrically about a central rotation axis of the driving end 713 of the driver 71. In the illustrated embodiment, the movable members 72 are spherical plain bearings.
Opposite ends of the first connecting rod 73 are connected to the driving end 713 and the first connecting member 75, respectively, by two of the movable members 72. Opposite ends of the second connecting rod 74 are connected to the driving end 713 and the second connecting member 76, respectively, by the other two of the movable members 72. The first connecting rod 73 is substantially parallel to the second connecting rod 74. A length of the second connecting rod 74 is longer than a length of the first connecting rod 73.
The first connecting member 75 and the second connecting member 76 are received through the slot 15. An end of the first connecting member 75 away from the first connecting rod 73 and an end of the second connecting member 76 away from the second connecting rod 74 are positioned above the top surface 11 of the mounting plate 10. A first guiding rail 751 is formed on a sidewall of the first connecting member 75 along a lengthwise direction of the first connecting member 75. A second guiding rail 761 is formed on a sidewall of the second connecting member 76 along a lengthwise direction of the second connecting member 76.
The sliding assembly 77 comprises a guiding member 771, a first sliding member 773 slidably engaged with the guiding member 771, and a second sliding member 775 also slidably engaged with the guiding member 771. The guiding member 771 is fixed on the top surface 11 of the mounting plate 10 and positioned adjacent to the slot 15. The first sliding member 773 and the second sliding member 775 are slidably sleeved on the guiding member 771. The first sliding member 773 is mounted to the first connecting member 75, and the second sliding member 775 is mounted to the second connecting member 76. The first sliding member 773 and the second sliding member 775 slide along the guiding member 771 substantially parallelly to the mounting plate 10. A first sliding portion 7731 extends from a side of the first sliding member 773, and slidably engages with the first guiding rail 751. Thus, the first sliding portion 7731 allows the first connecting member 75 to slide along a lengthwise direction of the first connecting member 75. A second sliding portion 7751 extends from a side of the second sliding member 775, and slidably engages with the second guiding rail 761. Thus, the second sliding member 7751 allows the second connecting member 76 to slide along a lengthwise direction of the second connecting member 76.
The cutting assembly 78 comprises a first fixing member 781 and a second fixing member 782. The first fixing member 781 and the second fixing member 782 are plates. The first fixing member 781 is fixed to an end of the first connecting member 75 away from the first connecting rod 73. The second fixing member 782 is fixed to an end of the second connecting member 76 away from the second connecting rod 74. The first fixing member 781 and the second fixing member 782 each comprise a first cutter 783, a second cutter 784, and a third cutter 785. Each first cutter 783 forms a substantially V-shaped cutting edge 7833. The cutting edges 7833 face each other, and an imaginary line between a plurality of vertices 7835 of the cutting edges 7833 is substantially parallel to the mounting plate 10. Each second cutter 784 forms a substantially V-shaped cutting edge 7843. The cutting edges 7843 face each other, and an imaginary line between a plurality of vertices 7845 of the cutting edges 7843 is substantially parallel to the mounting plate 10.
Each third cutter 785 is located between one corresponding first cutter 783 and one corresponding second cutter 784. The each third cutter 785 forms a substantially V-shaped cutting edge 7853. The cutting edges 7853 face each other, and an imaginary line between a plurality of vertices 7855 of the cutting edges 7853 is substantially parallel to the mounting plate 10. A distance between the vertices 7855 of the cutting edges 7853 is smaller than a distance between the vertices 7835 of the cutting edges 7833 and smaller than a distance between the vertices 7845 of the cutting edges 7843. The distance between the vertices 7835 of the cutting edges 7833 is substantially equal to the distance between the vertices 7845 of the cutting edges 7843. Therefore, the first cutters 783 and the second cutters 784 cut the cover layer 201, and the third cutters 785 cut the fiber of the cables 200.
In assembly, the first peeling member 30 and the second peeling member 50 are mounted on the top surface 11 of the mounting plate 10, and the driver 71 is mounted to the bottom surface 13 of the mounting plate 10. The first connecting rod 73 connects the driving end 713 to the first connecting member 75, and the second connecting rod 74 connects the driving end 713 to the second connecting member 76. The guiding member 771 of the sliding assembly 77 is mounted on the top surface 11 of the mounting plate 10. The first sliding member 773 is mounted to the first connecting member 75, and the second sliding member 775 is mounted to the second connecting member 76. The first fixing member 781 is mounted to the first connecting member 75, and the second fixing member 782 is mounted to the second connecting member 76. The first cutters 783, the second cutters 784, and the third cutters 785 are mounted correspondingly to the first mounting member 781 and the second mounting member 782, such that the third cutter 785 is located between the first cutter 783 and the second cutter 784.
In use, the cable holding member 300 is fixed to the first peeling member 30. The cable 200 is received through the first cutters 783, the second cutters 784, and the third cutters 785, and one end of the cable 200 away from the cable holding member 300 is fixed to the second peeling member 50. The driving body 711 rotates the driving end 713 back and forth at a high speed, which causes the first connecting member 75 and the second connecting member 76 to move towards and away from each other at a high speed. As the first connecting member 75 and the second connecting member 76 move toward and away from each other, the engagement between the first and second guiding rails 751, 761 and the first sliding portion 7731 and the second sliding portions 7751, respectively, prevent the first and second connecting members 75, 76 from moving perpendicularly relative to the mounting plate 10. Simultaneously, the first sliding member 773 and the second sliding member 775 slide along the guiding member 771 towards and away from each other. When the first connecting member 75 and the second connecting member 76 move toward each other, the cutting edges 7853 of the third cutters 785 cut the cover layer 201 and the fiber of the cable 200, and the first cutters 783 and the second cutters 784 cut portions of the cover layer 201. Then, the first peeling member 30 and the second peeling member 50 are driven to move away from each other, so that the cut portions of the cover layer 201 at opposite sides of the third cutter 785 are cut off from the cable 200. When the cutting is done or finished, the first peeling member 30 and the second peeling member 50 are returned to an original state, respectively.
Because the driver 71 drives the first connecting member 75 and the second connecting member 76 to move parallelly relative to the mounting plate 10, and the first peeling member 30 and the second peeling member 50 are driven to move toward and away from the slot 15, the first cutters 783, the second cutters 784, and the third cutters 785 cooperatively cut and remove the cover layer 201 of the cable 200. Therefore, the above cutting-motions are simpler and faster. Since the respective structural elements of the cable peeling and cutting device 100 are arranged at opposite sides of the mounting plate 10, a required size of the cable peeling and cutting device 100 is reduced. A structure of the cable peeling and cutting device 100 is simpler, and a cutting action is also simpler. Thus, the cable peeling and cutting device 100 has a longer usage life.
In an alternative embodiment, the first fixing member 781, the second fixing member 782, and the sliding assembly 77 can be omitted, such that the first cutters 783, the second cutters 784, and the third cutters 785 are directly mounted to the first connecting member 75 and the second connecting member 76. The second peeling member 50 and the second cutter 784 can be omitted, such that only the cover layer 201 of the cable 200 at one side of the third cutters 785 is cut when the driving body 711 rotates the driving end 713.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
