[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a terminal strip narrowing and riveting machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The strip passage groove is located below the positioning groove. The riveting end of the riveting mechanism is provided with a pressing block for pressing down the wire positioning die and a riveting head for cooperating with the riveting bottom die.

[0006] Furthermore, the narrow strip cutting mechanism includes a fixed die mounted on the machine base and connected to the discharge end of the strip guide rail, a movable die cooperating with the fixed die, and a strip cutting drive module for driving the movable die to move relative to the fixed die, with a material dropping channel formed between the fixed die and the movable die.

[0007] Furthermore, the fixed die is provided with a lifting slide groove, and the fixed die is slidably mounted in the lifting slide groove. The cutting edge of the fixed die is located at the top end of the lifting slide groove, and the inner wall of the lifting slide groove and the movable die form a material dropping channel.

[0008] Furthermore, a discharge hole is provided in the middle of the fixed die, and the discharge hole is connected to the material discharge channel.

[0009] Furthermore, the cutting drive module includes a fixed base fixedly connected to the bottom end of the fixed die, a cutting driver mounted on the fixed base, and a drive block mounted on the cutting end of the cutting driver. The cutting driver is used to drive the drive block to reciprocate. The drive block is provided with a drive groove. The bottom end of the movable die is provided with a shaft. The shaft extends into the drive groove and abuts against the inner wall of the drive groove.

[0010] Furthermore, the fixed base is provided with a translation groove, and the drive block is slidably disposed in the translation groove.

[0011] Furthermore, the bottom end of the movable die is provided with an insertion hole and a locking hole that intersects and communicates with the insertion hole.

The lower pressing block presses down on the top of the wire positioning mold, causing the wire positioning mold to... The wire moves downwards until the end to be riveted is placed on the terminal of the terminal strip. The riveting head and riveting die work together to rivet the end of the wire onto the terminal strip. Simultaneously, as the lower pressure block drives the wire positioning die downwards, the strip groove of the wire positioning die causes the narrowed terminal strip to move downwards, separating the strip from the corresponding riveted terminal. After the riveting end of the riveting mechanism drives the lower pressure block and riveting die upwards and resets, the wire positioning die causes the riveted wire to elastically move upwards. At this point, the wire with the riveted terminal can be removed. As the terminal strip moves, the waste strip will move out along the strip groove. This invention, by narrowing the strip through a strip-cutting mechanism, can meet the normal riveting requirements of wires with shorter ends to the terminals on the terminal strip.

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] like Figures 1 to 8 As shown, the present invention provides a terminal strip narrowing and riveting machine, which includes a base 1, a strip guide rail 2 mounted on the base 1 for guiding the terminal strip 30, a feeding mechanism 3 mounted on the base 1 for driving the terminal strip 30 within the strip guide rail 2, a strip narrowing mechanism 4 located at the discharge end of the strip guide rail 2, a riveting bottom die 5 mounted on the base 1 and located on the discharge side of the strip narrowing mechanism 4, and a riveting... The pressing mechanism 6 and the wire positioning mold 7, which is elastically set on the base 1 and located outside the riveting bottom mold 5, are provided. The tape cutting mechanism 4 is used to cut the tape body of the terminal tape 30 into narrower shape. The wire positioning mold 7 is provided with a tape passage groove 8 recessed inward on the side close to the riveting bottom mold 5. The top of the wire positioning mold 7 is provided with a positioning groove 9 recessed. The tape passage groove 8 is located below the positioning groove 9. The riveting end of the riveting mechanism 6 is provided with a pressing block 10 for pressing down the wire positioning mold 7 and a riveting head 11 for cooperating with the riveting bottom mold 5.

[0028] In practical applications, wire 29 is placed in the positioning groove 9 of wire positioning mold 7. The feeding mechanism 3 drives the terminal strip 30 to move intermittently along the strip guide 2 toward the riveting bottom mold 5. Before the terminal strip 30 is conveyed to the top of the riveting bottom mold 5, the strip narrowing mechanism 4 narrows the strip body of the terminal strip 30. The narrowed terminal strip 30 moves into the strip passage groove 8 of the riveting bottom mold 5. The terminal of the terminal strip 30 is located on the top surface of the riveting bottom mold 5, and the end of wire 29 to be riveted is located above the terminal of the terminal strip 30. At this time, the riveting mechanism 6 is started. The riveting end of the riveting mechanism 6 drives the lower pressing block 10 and the riveting head 11 to move down synchronously. The lower pressing block 10 presses down on the top of the wire positioning mold 7, so that the wire positioning mold 7 and the wire... 29 moves down until the end of wire 29 to be riveted is placed on the terminal of terminal strip 30, and the riveting head 11 and the riveting bottom die 5 have riveted the end of wire 29 to be riveted on the terminal of terminal strip 30. At the same time, as the lower pressing block 10 drives the wire positioning die 7 to move down, the tape groove 8 of the wire positioning die 7 will drive the tape body of the narrowed terminal strip 30 to move down, so that the tape body of the terminal strip 30 is separated from the corresponding riveted terminal. After the riveting end of the riveting mechanism 6 drives the lower pressing block 10 and the riveting bottom die 5 to move up and reset, the wire positioning die 7 will drive the riveted wire 29 to move up elastically. At this time, the wire 29 with the riveted terminal can be removed. As the terminal strip 30 moves, the waste tape after riveting will move out along the tape groove 8. This utility model uses a tape-narrowing mechanism 4 to narrow the tape body of the terminal tape 30, which can meet the normal riveting requirements of the short wire 29 to be riveted and the terminal on the terminal tape 30.

[0029] In practical applications, the lower pressure block 10 first contacts the wire positioning mold 7, and then the riveting head 11 cooperates with the riveting bottom mold 5.

[0030] Specifically, the feeding mechanism 3 can be the existing belt feeding mechanism in the riveting machine, which will not be described in detail here.

[0031] In this embodiment, the narrow strip cutting mechanism 4 includes a fixed die 12 mounted on the base 1 and connected to the discharge end of the strip guide rail 2, a movable die 13 cooperating with the fixed die 12, and a strip cutting drive module 14 for driving the movable die 13 to move relative to the fixed die 12. A material dropping channel is formed between the fixed die 12 and the movable die 13.

[0032] In practical applications, when the terminal strip 30 moves between the fixed die 12 and the movable die 13, the cutting drive module 14 drives the movable die 13 to move relative to the fixed die 12, so that the movable die 13 cooperates with the fixed die 12 to cut the terminal strip 30, so that the terminal strip 30 is narrowed. The waste generated by cutting the terminal strip 30 will enter the discharge channel and can be discharged in time.

[0033] In this embodiment, the fixed die 12 is provided with a lifting slide 15. The fixed die 12 is slidably disposed within the lifting slide 15, and the cutting edge of the fixed die 12 is located at the top end of the lifting slide 15. The inner wall of the lifting slide 15 and the movable die 13 form a material discharge channel, and the cutting edges of the fixed die 12 and the movable die 13 correspond and cooperate. In practical applications, when the movable die 13 moves relative to the fixed die 12, the movable die 13 moves up and down along the lifting slide 15, which improves the movement stability of the movable die 13 and is beneficial for forming a material discharge channel.

[0034] In this embodiment, a discharge hole 16 communicating with the lifting slide 15 is provided in the middle of the fixed die 12, and the discharge hole 16 is connected to the dropping channel. In practical applications, waste material falling into the dropping channel will be discharged from the discharge hole 16, which facilitates the directional discharge of waste material.

[0035] In this embodiment, the cutting drive module 14 includes a fixed base 17 fixedly connected to the bottom end of the fixed die 12, a cutting driver 18 mounted on the fixed base 17, and a drive block 19 mounted on the cutting end of the cutting driver 18. The cutting driver 18 is used to drive the drive block 19 to move back and forth. The drive block 19 is provided with a drive groove 20. The bottom end of the movable die 13 is provided with a shaft 21. The shaft 21 extends into the drive groove 20 and abuts against the inner wall of the drive groove 20.

[0036] In practical applications, the cutting driver 18 drives the driving block 19 to reciprocate. The inner wall of the driving groove 20 of the reciprocating driving block 19 abuts against the shaft 21, thereby driving the shaft 21 and the movable die 13 to move up and down along the lifting groove 15.

[0037] In this embodiment, the fixed base 17 is provided with a translation groove 22, and the driving block 19 is slidably disposed in the translation groove 22. During the reciprocating movement of the driving block 19, the outer wall of the driving block 19 is slidably connected to the inner wall of the translation groove 22, and the translation groove 22 plays a guiding role for the driving block 19, thereby improving the stability of the reciprocating movement of the driving block 19.

[0038] In this embodiment, the bottom end of the movable die 13 is provided with an insertion hole 23 and a locking hole 24 that intersects and communicates with the insertion hole 23. Preferably, the central axis of the insertion hole 23 is perpendicular to the central axis of the locking hole 24. The locking hole 24 is detachably connected to a locking fastener. One end of the shaft 21 is inserted into the insertion hole 23, and the locking fastener is used to lock the shaft 21 onto the movable die 13. This structural design facilitates the disassembly and assembly of the shaft 21 and ensures a firm assembly between the shaft 21 and the movable die 13.

[0039] Specifically, the cutting driver 18 can be a cylinder, the locking hole 24 is a threaded hole, the locking fastener is a bolt that is threaded into the threaded hole, and the end face of the bolt abuts against the shaft 21 to lock the shaft 21.

[0040] In this embodiment, the movable die 13 is provided with a guide slope 25 on the side near the discharge hole 16, and the guide slope 25 is inclined towards the discharge hole 16. In practical applications, when the waste enters the discharge channel, the guide slope 25 in the discharge channel will guide the waste to the discharge hole 16, so that the waste can be discharged smoothly and stably from the discharge hole 16.

[0041] In this embodiment, the wire positioning mold 7 is elastically connected to the base 1 via an elastic element. The elastic force applied by the elastic element to the wire positioning mold 7 is directed towards the lower pressure block 10. Specifically, the elastic element is a spring, and its two ends are elastically connected to the bottom surface of the wire positioning mold 7 and the base 1, respectively. This structure allows the wire positioning mold 7 to move up and down relative to the base 1, and the wire positioning mold 7 can automatically reset under the restoring force of the elastic element.

[0042] In this embodiment, the base 1 is provided with a pressing space and a stroke hole 27 perpendicularly communicating with the pressing space. The elastic element is located in the pressing space, and the bottom end of the wire positioning mold 7 is provided with a limiting block 28 extending into the stroke hole 27. When the elastic element is in the extended state, the limiting block 28 abuts against the top wall of the stroke hole 27 to limit the wire positioning mold 7 and prevent the wire positioning mold 7 from separating from the base 1 under the elastic force of the elastic element. When the wire positioning mold 7 moves downward under the downward pressure of the pressing block 10, the wire positioning mold 7 moves downward along the pressing space and compresses the elastic element, and the limiting block 28 moves downward along the stroke hole 27, improving the stability of the wire positioning mold 7's vertical movement. Specifically, the stroke hole 27 limits the vertical movement stroke of the wire positioning mold 7, ensuring the positional accuracy and stability of the wire positioning mold 7's vertical movement.

[0043] Specifically, a cutting mechanism is provided on the side of the riveting bottom die 5 away from the narrow strip cutting mechanism 4. In practical applications, after the waste strip generated after riveting is output along the strip passage 8, the cutting mechanism cuts the waste strip at regular intervals or at fixed lengths to prevent the waste strip from being too long and affecting the movement of the terminal strip 30, and to facilitate the collection of the waste strip.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
