[0002] With the continuous development of power facilities, the power system has become more and more perfect. It is known that electrical connections are to be made between various components of the power system. Typically, power terminals are terminated at the ends of cables and are configured to mate with corresponding power terminals.

[0003] When power terminals are terminated at the ends of cables, especially European plug terminals, there is a lack of automated equipment to achieve the connection. In the prior art, a terminal crimping machine is used to crimp terminals and wires together. The existing terminal crimping machines can only achieve the assembly of single or two wires and terminals. Moreover, before assembling the wires and terminals, the outer insulating layer of the cable wires needs to be manually removed or processed by a dedicated removal processing device before the terminals can be connected. Also, when there are a large number of cables, they are prone to entanglement, and it is inconvenient to convey and clamp the cables on the workbench. During conveyance and operation at each station, the cables are prone to loosening or not being timely, resulting in low work efficiency.

[0004] Therefore, there is a need to provide an European plug automatic terminal machine to address the above problems. Summary of the Invention

Detailed Embodiments

[0027] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant accompanying drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figure 1 As shown, an European plug automatic terminal machine includes a frame 1, a terminal conveyor belt 2, a wire feeding turntable 7, a peeling and pulling mechanism 15, a wire twisting mechanism 16 and a terminal inserting sleeve mechanism 17. A terminal conveyor belt 2 is provided on the side of the frame 1. The terminal conveyor belt 2 is sleeved on conveyor belt wheels 3. The conveyor belt wheels 3 are located at the left and right ends of the frame 1. The axle of one of the conveyor belt wheels 3 is connected to a driving motor 4. Driven by the driving motor 4, the conveyor belt wheel 3 drives the terminal conveyor belt 2 to rotate.

[0030] In an embodiment of the present invention, see Figure 1 As shown, the terminal conveyor belt 2 also winds around the wire feeding turntable 7. The wire feeding turntable 7 is located in the middle above the terminal conveyor belt 2. An incoming wire pressing piece 5 is installed on the frame 1 in front of the wire feeding turntable 7, and an outgoing wire pressing piece 6 is installed on the frame 1 behind the wire feeding turntable 7.

[0031] As a preferred embodiment of the present invention, transmission teeth 8 are further provided on the outer side wall of the wire feeding turntable 7. The transmission teeth 8 are engaged with the inner side teeth of the terminal conveyor belt 2 to increase the friction between the wire feeding turntable 7 and the terminal conveyor belt 2 and avoid slipping between the two.

[0032] The wire feeding turntable 7 is installed on a driving shaft 9. The driving shaft 9 is connected to a servo motor 10. The servo motor 10 is fixed on the frame 1. In an embodiment of the present invention, see Figure 1 and Figure 2 As shown, a number of wire feeding clamping blocks 11 are equidistantly provided on the outer side of the terminal conveyor belt 2. Two adjacent wire feeding clamping blocks 11 form a clamping assembly for the cable. A tension spring 12 is connected between two adjacent wire feeding clamping blocks 11. Under the pulling force of the tension spring 12, the two adjacent wire feeding clamping blocks 11 clamp the cable placed in the middle thereof, and the cable is moved as the terminal conveyor belt 2 rotates.

[0033] See Figure 1 and Figure 6 As shown, a guiding ring 13 is provided on one side of the wire feeding turntable 7 on the frame 1. The cross section of the guiding ring 13 is U-shaped and is located between the wire feeding turntable 7 and the frame 1 for guiding and bending the end of the cable; a side pressing ring 14 is provided on the side of the wire feeding turntable 7. The side pressing ring 14 is arranged between the guiding ring 13 and the terminal conveyor belt 2 on the wire turntable 7. After the end of the cable is guided and bent by the U-shaped guiding ring 13, it abuts against the side pressing ring 14. The side pressing ring 14 is used to support the processing of the cable joint.

[0034] See Figure 1 As shown, a peeling and pulling mechanism 15, a wire twisting mechanism 16 and a terminal inserting sleeve mechanism 17 are successively installed on the frame 1 on the side of the side pressing ring 14. See Figure 3As shown in the figure, the peeling and pulling mechanism 15 includes a peeling blade 18, a fixed clamp 19, a clamping cylinder 20, a telescopic rod 21, and a pulling cylinder 22. Among them, the peeling blade 18 is installed on the fixed clamp 19. The number of fixed clamps 19 is two and they are arranged in a V shape. The fixed clamps 19 are hinged to each other. A clamping cylinder 20 is installed between the fixed clamps 19. The expansion and contraction of the clamping cylinder 20 drives the opening or closing of the fixed clamps 19 to perform clamping. The middle part of the rear end of the fixed clamp 19 is connected to the pulling cylinder 22 through the telescopic rod 21. The pulling cylinder 22 is fixed on the frame 1. The telescopic rod 21 is arranged along the radial direction of the wire feeding turntable 7, which is convenient for driving the fixed clamp 19 and the peeling blade 18 to move towards the side pressing ring 14 when the pulling cylinder 22 drives the telescopic rod 21 to expand and contract. When the fixed clamp 19 moves to the position of the cable, the cable is located between the fixed clamps 19 and the clamping cylinder 20 drives the fixed clamps 19 to close. The peeling blade 18 on the fixed clamp 19 first cuts off the outer wall of the clamped cable, and then pulls it under the drive of the pulling cylinder 22 to peel off the outer wall of the cut cable, thus exposing the joint of the cable.

[0035] See Figure 4 As shown in the figure, the stranding mechanism 16 includes a stranding clamp 23, a stranding rotating shaft 24, a stranding driving seat 25, a stranding motor 29, and a stranding cylinder 30. Among them, the stranding cylinder 30 is installed on the frame 1. The piston rod of the stranding cylinder 30 is connected to the stranding driving seat 25. A stranding motor 29 is installed on the stranding driving seat 25. The stranding motor 29 is connected to the stranding main shaft 28. A driving gear ring 27 is installed on the stranding main shaft 28. A driven gear ring 26 is connected to the side of the driving gear ring 27. In an embodiment of the present invention, the number of the driven gear rings 26 is two and they are distributed on both sides of the driving gear ring 27. The driven gear ring 26 is installed on the stranding rotating shaft 24, and a stranding clamp 23 is installed on the stranding rotating shaft 24;

[0036] When performing stranding operation on the exposed joint of the cable, under the drive of the stranding cylinder 30, the stranding driving seat 25 moves towards the side pressing ring 14, and the joint of the cable is inserted into the stranding clamp 23. Under the drive of the stranding motor 29, the two stranding clamps 23 rotate simultaneously to wind the joint of the cable they hold into strands. Then the stranding motor 29 pauses working, and under the drive of the stranding cylinder 30, the stranding driving seat 25 is driven to reset, completing the stranding operation.

[0037] See Figure 5As shown, the terminal sleeve mechanism 17 includes a sleeve feeding claw 32, a pushing cylinder 33 and a sleeve heat shrinking clamp 34. Among them, the sleeve heat shrinking clamp 34 is installed outside the sleeve feeding claw 32, and the sleeve heat shrinking clamp 34 is installed at the front end of the piston rod of the pushing cylinder 33. Among them, driving devices for driving the clamping of the sleeve feeding claw 32 and the sleeve heat shrinking clamp 34 are installed on both the sleeve feeding claw 32 and the sleeve heat shrinking clamp 34. The driving device is preferably an electric cylinder or an electric push rod. The sleeve feeding claw 32 is used to clamp the terminal sleeve 31;

[0038] After the terminal sleeve 31 is clamped by the terminal sleeve 31, under the push of the pushing cylinder 33, the terminal sleeve 31 is stuck on the joint of the cabled cable. Then, under the clamping and heating of the sleeve heat shrinking clamp 34, the terminal sleeve 31 is heat shrunk and connected to the joint of the cable. Finally, the sleeve feeding claw 32 and the sleeve heat shrinking clamp 34 open and reset with the pushing cylinder 33.

[0039] The working principle of the present invention is:

[0040] When processing the European plug terminals of the cable, the cable is clamped onto the wire feeding clip block 11 of the terminal conveyor belt 2 on one side of the incoming wire pressing piece 5, and then enters one side of the incoming wire pressing piece 5 along with the movement of the terminal conveyor belt 2 and moves circumferentially along the wire feeding turntable 7. The joint of the cable is limited by the guiding ring 13 and the side pressing ring 14 and is located outside the side pressing ring 14. Then, it successively passes through the peeling and pulling mechanism 15, the stranding mechanism 16 and the terminal sleeve mechanism 17 for operation. After the automatic processing of the European plug terminals is completed, it is output from one side of the outgoing wire pressing piece 6. The cable on the terminal conveyor belt 2 can be taken off on one side of the outgoing wire pressing piece 6, and the operation is convenient and fast.

[0041] The technical principle of the present invention is described above in combination with specific embodiments, which is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solution falling within the idea of the present invention belongs to the protection scope of the present invention.
