[0003] With respect to the above-mentioned prior art, during the wire crimping process, the copper wire of the conductor / cable needs to be inserted into the pin sleeve to be crimped in order to achieve the purpose of pressing and forming in the subsequent wire crimping. However, due to the different length specifications of the conductors, most of the current processes still use manual labor to insert the wire core of the conductor into the pin sleeve to be crimped, resulting in insufficient automation.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In order to solve the technical problem of insufficient automation in manually inserting the core of a wire into a pin socket to be crimped, the utility model provides a wire feeding device that can realize automatic insertion to connect the wire crimping action of subsequent equipment.

[0031] It should be noted that the wire feeding device described in the present invention is used for but not limited to crimping between wires and pins. For the sake of convenience, in the present invention, only the wire supply of the wire feeding device for crimping between wires and pins is used as an example for explanation. The principle of applying the wire feeding device to other types of equipment is essentially the same as the principle of crimping and supplying wires applied to other cables and terminals, and will not be elaborated here.

[0032] See also Figure 1-5The utility model provides a wire feeding device for conveying wires to a pin crimping device. The wire feeding device includes a conveyor belt 1, an elastic telescopic mechanism 2, an insertion mechanism 3, a pushing mechanism 4 and a discharge mechanism 5. The conveyor belt 1 is used to convey the wires to the pin crimping device; a plurality of the elastic telescopic mechanisms 2 are arranged on the conveyor belt 1 at equal distances along the conveying direction, and the conveying direction is the conveying direction of the conveyor belt 1. According to actual needs, the spacing distance can be controlled to form a tight arrangement or a relatively loose arrangement; a plurality of the insertion mechanisms 3 are arranged one by one at the movable end of the elastic telescopic mechanism 2, and are used to insert the wires perpendicular to the conveying direction and expose the wire cores of the wires. , and can move linearly along the length direction of the elastic telescopic mechanism 2; the pushing mechanism 4 is arranged on one side of the conveyor belt 1, and is used to push the insertion mechanism 3 to move linearly perpendicular to the conveying direction. Under the pushing action, the wire core 71 is pushed into the pin sleeve for crimping. Under the contraction action, the elastic telescopic mechanism 2 is used to rebound and retract the crimped pin; the unloading mechanism 5 is arranged at the bottom of the conveyor belt 1, and is used to push the wire 7 off from the insertion mechanism 3. When the insertion mechanism 3 moves to the bottom following the conveyor belt 1, the socket is converted from upward to downward. At this position, it can be pushed out of the socket by squeezing the unloading mechanism 5, thereby achieving the effect of automatic unloading.

[0033] In this embodiment, please refer to Figure 1 The staff will plug the wires one by one into the insertion mechanism 3 moved to the starting end, that is, the right end of the conveyor belt 1. The insertion mechanism 3 with the wires inserted is transported by the conveyor belt 1 to the left end of the conveyor belt 1, that is, the position of the pushing mechanism 4. The transportation is paused, and the pushing mechanism 4 is started to push the insertion mechanism 3 to push the wire core 71 into the pin sleeve for crimping. Then the pushing mechanism 4 contracts, and the elastic telescopic mechanism 2 rebounds to pull out the wire with the crimped pin, and the conveyor belt 1 is started to continue conveying, and it is transported to the bottom and contacts the unloading mechanism 5. The wire with the crimped pin is squeezed and pushed by the unloading mechanism 5 and falls downward.

[0034] In one embodiment, see Figure 2 and Figure 3 The elastic telescopic mechanism 2 includes a base 21, a guide seat 22, a spring 23 and a slide 24. The base 21 is arranged on the conveyor belt 1, and the guide seat 22 is arranged on the base 21. A slide groove is provided on the guide seat 22. The spring 23 is arranged in the slide groove, and one end is connected to the slide 24. The spring 23 provides elastic force. After compression, the slide 24 can be elastically pushed back to move. The slide 24 is slidably connected to the slide groove. The insertion mechanism 3 is arranged on the top of the slide 24, and the sliding direction of the slide 24 can be guided by the slide groove on the guide seat 22.

[0035] In this embodiment, under the push of the pushing mechanism 4, the slide 24 can slide along the slide groove and compress the spring 23. Under the contraction of the pushing mechanism 4, the spring 23 rebounds, thereby resetting the slide 24.

[0036] In one embodiment, see Figure 3 The insertion mechanism 3 includes a U-shaped frame 31 and an extension edge 32. The U-shaped frame 31 is fixed to the top of the slide 24. The U-shaped opening of the U-shaped frame 31 faces upward, which is convenient for inserting the wire. The extension edge 32 is arranged at the top of the U-shaped frame 31, and the extension edge 23 serves as the contact point of the pushing mechanism 4 to push the U-shaped frame 31.

[0037] Furthermore, to control the position of wire insertion and enable rapid positioning, a positioning plate 25 is hingedly connected to the base 21. A torsion spring is disposed between the positioning plate 25 and the base 21, elastically pulling the positioning plate 25 perpendicular to the base 21. The positioning plate 25 is provided with an open slot 2501 for the core 71 of the wire 7 to pass through and abut against the outer sheath 72 of the position-limiting wire 7, thereby defining its insertion position and exposing the core 71. Each wire is positioned at the intersection of the core 71 and the outer sheath 72, regardless of the length of the wire. Furthermore, the outer sheath 72 is primarily inserted into the U-shaped frame 31, providing a more stable insertion than the open slot 2501 on the positioning plate 25. When pushed, the positioning plate 25 can be pushed and flipped until it is fully engaged with the pin socket.

[0038] It can be understood that the torsion spring adopts a torsion spring with weaker elasticity so that its elastic action does not affect the insertion of the U-shaped frame 31 on the wire 7, that is, the clamping force of the U-shaped frame 31 on the wire is greater than the elastic force of the torsion spring. When the insertion strength is insufficient, a connection mode in which an elastic clip is set in the U-shaped frame 31 to clamp the wire 7 can be adopted.

[0039] Further, in order to form a push action corresponding to the extension along position 32, please refer to Figure 5 The pushing mechanism 4 includes a pneumatic push rod 41 and a pushing frame 42. The pneumatic push rod 41 is installed on one side of the conveyor belt 1 through a bracket. The pushing frame 42 is arranged at the movable end of the pneumatic push rod 41, and the position of the pushing frame 42 is opposite to the position of the extension edge 32. The pushing frame 42 is driven to push by the extension and contraction of the pneumatic push rod 41.

[0040] Furthermore, in order to improve the stability of the pushing action, the number of the extension edges 32 is two, and the two extension edges 32 are symmetrically distributed on the top of the U-shaped frame 31, and two push rods 43 are provided on the pushing frame 42, and the two push rods 43 are respectively opposite to the two extension edges 32.

[0041] In one embodiment, see Figure 4 In order to form a blanking action, the blanking mechanism 5 includes a triangular plate portion 51 and a straight plate portion 52. The straight plate portion 52 is arranged on one side of the triangular plate portion 51, and the inclined surface of the triangular plate portion 51 faces downward and is located between the positioning plate 25 and the U-shaped frame 31. The tip of the triangular plate is located at the top, against the upper side of the wire. During the guide movement to the right, it is gradually pushed down along the inclined surface until it is pushed out of the U-shaped frame.

[0042] Furthermore, a receiving hopper 6 is provided below the conveyor belt 1 . The receiving hopper 6 is located directly below the triangular plate portion 51 and is used to receive the wires that fall from the U-shaped frame.

[0043] In one embodiment, the base 21 is a flexible base, which can be made of rubber and has a trapezoidal shape to provide a deformation amount and reduce the impact on the guide seat 22 when the conveyor belt 1 is in the flip position.

[0044] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: during operation, the worker only needs to insert the wire into the U-shaped frame 31, and make the outer sheath 72 abut against the positioning plate 25, and make the wire core 71 pass through the open groove 2501. Under the subsequent transportation of the conveyor belt 1, it is transported to the pushing mechanism 4 and stops, and the pneumatic push rod 41 is extended to push the pushing frame 42 against the U-shaped frame 31, driving the slide 24 to compress the spring 23. At the same time, the wire core 71 is inserted into the needle sleeve of the pin for crimping. After crimping, the pneumatic push rod 41 contracts, and the spring 23 rebounds, bringing the wire and the crimped pin out, and the conveyor belt 1 continues to transport, and the above steps are followed again to crimp the next wire and the pin; when the crimped and inserted wire moves to the bottom of the conveyor belt 1 and contacts the triangular plate portion 51, the wire is pushed by the oblique surface to make it break away from the U-shaped frame downward and fall into the receiving hopper 6.

[0045] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
