[0002] Wire harness crimping production is the process of connecting cable conductors and connectors (terminals, connectors, etc.) through a crimping process. Terminals are key components in wire harness connections and are usually made of copper, aluminum, tinned copper and other materials. Appropriate terminals must be selected based on electrical requirements and working environment. This process is commonly used in automotive, electronic equipment, home appliances, communications equipment and other fields.

[0003] During the production process, when performing terminal crimping, multiple wire harnesses are generally crimped at the same time.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] Please refer to 1-8, an automatic crimping machine for wire harness connection processing, including a base 1, a stretching mechanism is slidingly provided on the base 1, and the stretching mechanism slides back and forth along the base 1; it also includes a reciprocating seat 2, which can slide along the wide side of the base 1, and a pressing member is provided on the reciprocating seat 2, and the reciprocating seat 2 has a first position, a second position and a third position respectively. In the first position, the pressing member receives the wire harness stretched by the stretching mechanism; in the second position, the pressing member passively presses and fixes the wire harness; in the third position, the pressing member passively releases the pressing and fixing of the wire harness; in the process of stretching the wire harness, the stretching mechanism causes the reciprocating seat 2 to slide from the third position to the first position, and causes the reciprocating seat 2 to fall into the reciprocating position after the wire harness is stretched. The stretching mechanism drives the reciprocating seat 2 to slide from the first position to the third position during the resetting process, and the reciprocating seat 2 is in the second position during the sliding process, and the lower pressing member presses the wire harness; the lower pressing member includes a plurality of pressing rods 21 slidably and rotatably arranged on the reciprocating seat 2, and a plurality of fixed tubes 23 are fixedly arranged on the reciprocating seat 2, and the plurality of pressing rods 21 correspond to the plurality of fixed tubes 23 one by one, and a protrusion 22 is fixedly provided on the pressing rod 21, and a spiral groove 24 is provided on the fixed tube 23, and the protrusion 22 is slidably arranged in the spiral groove 24; it also includes a wire feeding assembly, which is used to assist the reciprocating seat 2 to send the crimped and cut wire harness to one side of the base 1, and the crimped wire harness is stretched by sliding the stretching mechanism 8, and then, The stretched wire harness is cut so that the wire harness is relaxed and falls onto the reciprocating seat 2 and is located between the pressure rods 21. The stretching mechanism 8 then slides and resets, and during the reset process, the reciprocating seat 2 slides from the first position to the second position. In this process, the pressure rod 21 moves downward, and under the action of the protrusion 22 and the spiral groove 24, the pressure rod 21 rotates during the downward movement, so that when the reciprocating seat 2 slides to the second position, the pressure rods 21 cooperate to press the wire harness to avoid the mess at the wire harness crimping. When the reciprocating seat 2 slides to the third position, the wire harness is sent to one side of the base 1, and the pressure rods 21 release the pressure on the wire harness, which is convenient for workers to check the crimping quality of the crimping. At the same time, the reciprocating seat 2 slides During the process, the wire feeding assembly simultaneously pushes the wire harness to one side of the base 1, which is used to assist the reciprocating seat 2 to send the wire harness to one side of the base 1, so as to avoid the wire harness becoming messy on the base 1, and facilitate workers to organize the wire harness after crimping. The pressure rod 21 does not contact the crimping joint of the wire harness. It is used to press the wire harness near the crimping joint position, so as to avoid the crimping position of the wire harness moving when the wire harness moves, resulting in messiness and inconvenience in observation; a sliding block 26 is fixedly provided on the reciprocating seat 2, and a sliding groove 11 is provided on the base 1. The sliding block 26 is slidably provided in the sliding groove 11. By providing the sliding block 26 and the sliding groove 11, the stability of the reciprocating seat 2 during the sliding process is improved.

[0042] Specifically, a lifting seat 3 is slidingly provided on the reciprocating seat 2, and a plurality of limiting rings 31 are fixedly provided on the lifting seat 3. The plurality of limiting rings 31 correspond to the plurality of pressure rods 21 one by one and are rotatably connected. The wiring harness is relaxed and falls between the pressure rods 21, and the reciprocating seat 2 slides. During the sliding process, the lifting seat 3 moves downward, and the pressure rod 21 is moved downward by the limiting ring 31. Under the action of the protrusion 22 and the spiral groove 24, the pressure rod 21 rotates during the downward movement, so that the pressure rod 21 can better press the wiring harness.

[0043] In an embodiment further provided by the present invention, a first guide block 32 is fixedly provided on the lifting seat 3, and a first guide groove 12 is provided on the base 1. The first guide block 32 is slidably provided in the first guide groove 12. When the first guide block 32 is located at both ends of the first guide groove 12, the reciprocating seat 2 is respectively located in the first position and the third position, and the lifting seat 3 is in an ascending state. At this time, the wiring harness can be dropped between the pressure rods 21, which is also convenient for removing the wiring harness. When the first guide block 32 is located in the middle straight area of the first guide groove 12, the reciprocating seat 2 is located in the second position, and the lifting seat 3 is in a descending state. At this time, the pressure rods 21 cooperate with each other to press the wiring harness, thereby avoiding the phenomenon that the crimping joint of the wiring harness becomes messy or moves during the sliding process of the reciprocating seat 2, which makes it inconvenient for workers to check the crimping joint.

[0044] Furthermore, a plurality of pulleys 4 are rotatably provided on the base 1, and a belt 41 is provided for transmission between the plurality of pulleys 4, a fixed block 42 is fixedly provided on the belt 41, a connecting rod 43 is fixedly provided on the fixed block 42, a connecting block 25 is fixedly provided on the reciprocating seat 2, and the connecting rod 43 is fixedly connected to the connecting block 25. The belt 41 drives the fixed block 42 and the connecting rod 43 to slide, so that the connecting rod 43 drives the reciprocating seat 2 to slide through the connecting block 25; in this embodiment, the belt 41 can be replaced by a chain, and the pulley 4 can be replaced by a sprocket to improve stability during operation.

[0045] Furthermore, the wire feeding assembly includes a cross bar 5 slidably set on the base 1, the cross bar 5 is fixedly connected to the fixed block 42, and a wire feeding rod 51 is slidably set on the cross bar 5. When the crimped wire harness is cut, the wire harness falls into each pressure rod 21. At the same time, the wire harness falls onto the base 1. When the reciprocating seat 2 slides, the wire feeding rod 51 pushes the wire harness, assisting the reciprocating seat 2 to send the wire harness to one side of the base 1, so as to avoid the wire harness tilting on the base 1 when the reciprocating seat 2 slides, which makes it inconvenient for workers to arrange the wire harness.

[0046] In an embodiment further provided by the present invention, a second guiding block 52 is fixedly arranged on the wire feeding rod 51, a second guiding groove 13 is arranged on the base 1, the second guiding block 52 is slidably arranged in the second guiding groove 13, a stop block 14 is rotatably arranged on the base 1, a torsion spring 15 is arranged between the stop block 14 and the base 1, the stop block 14 is in abutting cooperation with the second guiding block 52. When the wire feeding rod 51 assists the reciprocating seat 2 to send the wire harness to one side of the base 1, the second guiding block 52 slides along the upper part of the second guiding groove 13. At this time, the wire feeding rod 51 is in a raised state for assisting in wire feeding. And during the sliding process, the stop block 14 is pushed to rotate against the force of the torsion spring 15 and passes through the stop block 14. When the wire feeding rod 51 is reset, under the action of the stop block 14, the wire feeding rod 51 moves downward, and the second guiding block 52 slides along the lower part of the second guiding groove 13. At this time, the wire feeding rod 51 is in a descending state, avoiding interference between the wire feeding rod 51 and the wire harness when the wire feeding rod 51 is reset.

[0047] In an embodiment provided by the present invention, a first spring 53 is arranged between the wire feeding rod 51 and the cross bar 5. Both ends of the first spring 53 are fixedly connected to the wire feeding rod 51 and the cross bar 5 respectively. When the wire feeding rod 51 assists in wire feeding, the first spring 53 is in a normal state. When the wire feeding rod 51 is reset, under the action of the stop block 14, the wire feeding rod 51 moves downward, and the first spring 53 extends, avoiding interference between the wire feeding rod 51 and the wire harness when the wire feeding rod 51 is reset. And after the reset is completed, under the reset action of the first spring 53, the wire feeding rod 51 extends out to facilitate the next assistance for the reciprocating seat 2 to send the wire.

[0048] Specifically, a U-shaped rod 6 is slidably arranged on the base 1, the U-shaped rod 6 is fixedly connected to the belt 41, a wedge-shaped block 61 is slidably arranged on the U-shaped rod 6, a push rod 81 is fixedly arranged on the stretching mechanism 8, both sides of the wedge-shaped block 61 are provided with inclined surfaces and are in abutting cooperation with the push rod 81 through the inclined surfaces. During the sliding process of the stretching mechanism 8, through the abutting of the push rod 81 and the inclined surfaces on the wedge-shaped block 61, the wedge-shaped block 61 is driven to slide with the U-shaped rod 6, so that the U-shaped rod 6 drives the belt 41 to slide, and the belt pulley 4 rotates, thereby enabling the belt 41 to drive the wire feeding rod 51 and the reciprocating seat 2 to slide.

[0049] In a further solution provided by the present invention, two abutting seats 7 are slidably arranged on the base 1, and both of the two abutting seats 7 are in abutting cooperation with the wedge block 61; second springs 71 are arranged between the two abutting seats 7 and the base 1, and two ends of each second spring 71 are fixedly connected to the abutting seat 7 and the base 1 respectively. During the process that the stretching mechanism 8 slides to stretch the wire harness, the push rod 81 abuts against the inclined surface of the wedge block 61. At this time, the U-shaped rod 6 and the wedge block 61 slide along with the push rod 81, and the reciprocating seat 2 and the wire feeding rod 51 are reset. After the reset is completed, the U-shaped rod 6 abuts against the base 1. At this time, the stretching mechanism 8 continues to slide, and the push rod 81 applies a downward force to the wedge block 61 through the inclined surface. At this time, the wedge block 61 pushes the abutting seat 7 to move downward and compresses the second spring 71. After the wedge block 61 moves downward, the push rod 81 passes through the wedge block 61 and continues to slide. After the stretching mechanism 8 finishes sliding, the wire harness is cut, and the wire harness drops between the pressing rods 21. Subsequently, the stretching mechanism 8 slides to clamp and stretch the next group of crimped wire harnesses. During the sliding process, it abuts against the inclined surface of the wedge block 61, and slides the U-shaped rod 6 by pushing the wedge block 61, so that the reciprocating seat 2 and the wire feeding rod 51 slide, and the wire harness is sent to one side of the base 1. In this embodiment, by setting the elastic force of the second spring 71, when the wedge block 61 is subjected to the thrust of the push rod 81, the wedge block 61 is made to push the U-shaped rod 6 to slide along with the push rod 81. At this time, the second spring 71 does not deform. When the U-shaped rod 6 slides to abut against the base 1, the push rod 81 pushes the wedge block 61 to slide through the inclined surface, so that the abutting seat 7 moves downward to compress the second spring 71, and after the push rod 81 passes through the wedge block 61, the wedge block 61 is reset by the second spring 71.

[0050] In the present invention, the mentioned stretching mechanism 8 and cutting mechanism are both prior arts, and their implementation manners and achieved technical effects are well-known attempts and conventional technical means to those skilled in the art, and will not be elaborated too much.

[0051] Working principle: During the wire harness crimping process, a crimping and cutting mechanism is provided on one side of the base 1. After the wire harness is crimped, the stretching mechanism 8 clamps and stretches the wire harness. The stretching mechanism 8 pulls the wire harness to slide above the reciprocating seat 2. Subsequently, the cutting mechanism on one side of the base 1 cuts the wire harness. After the wire harness is cut, each wire harness relaxes and falls between the respective pressure rods 21. Then, the stretching mechanism 8 releases the clamping of the crimping part of the wire harness. Subsequently, the stretching mechanism 8 slides again to clamp the next group of crimped wire harnesses. During the sliding process, the push rod 81 on the stretching mechanism 8 abuts against the inclined surface on the wedge block 61. At this time, the U-shaped rod 6 is not restricted, enabling the push rod 81 to push the U-shaped rod 6 to slide through the wedge block 61. At the same time, the U-shaped rod 6 drives the belt 41 to slide, causing the pulley 4 to rotate. The belt 41 drives the fixed block 42, the cross bar 5, the connecting rod 43, and the connecting block 25 to slide towards one side of the base 1. When the connecting block 25 drives the reciprocating block and the lifting seat 3 to slide, the lifting block slides downward under the action of the first guide block 32 and the first guide groove 12. The lifting block drives multiple pressure rods 21 to move downward through the limiting ring 31. And during the downward movement of the pressure rods 21, under the action of the convex block 22 and the spiral groove 24, they rotate 90°, pressing the wire harness between the respective pressure rods 21 to prevent the crimping part of the wire harness from becoming messy. At the same time, when the cross bar 5 drives the wire feeding rod 51 to slide, the wire feeding rod 51 pushes the wire harness, assisting the sliding of the reciprocating seat 2, sending the wire harness to one side of the base 1, reducing the phenomenon of entanglement and mess of the wire harness during movement, facilitating manual sorting. And after being sent to one side of the base 1, the lifting seat 3 rises under the action of the first guide block 32 and the first guide groove 12, causing the pressure rods 21 to rotate and rise, releasing the restriction on the wire harness by the pressure rods 21. At this time, the worker can check the crimping parts on each wire harness and remove and sort the wire harness. At this time, the U-shaped rod 6 slides to the position of another abutting seat 7, and the U-shaped rod 6 abuts against the base 1 and cannot continue to slide. At this time, the stretching mechanism 8 continues to slide, and the push rod 81 applies a force to the inclined surface on the wedge block 61, causing the wedge block 61 to press down the abutting seat 7 and compress the second spring 71. The wedge block 61 moves downward, and the stretching mechanism 8 continues to slide, causing the push rod 81 to pass through the wedge block 61. When the stretching mechanism 8 clamps the wire harness and slides to stretch the wire harness, the push rod 81 on the stretching mechanism 8 abuts against the other inclined surface of the wedge block 61 and pushes the U-shaped rod 6 to slide through the wedge block 61, thereby driving the reciprocating seat 2 and the wire feeding rod 51 to reset. It should be noted that when the wire feeding rod 51 is reset, under the action of the stop block 14 and the second guide groove 13, the wire feeding rod 51 descends, stretching the first spring 53, causing the second guide block 52 to slide below the second guide groove 13 to complete the reset of the wire feeding rod 51, preventing interference between the wire feeding rod 51 and the wire harness clamped by the stretching mechanism 8 during the reset process. And after the wire feeding rod 51 completes the reset, under the reset action of the first spring 53, the wire feeding rod 51 rises, facilitating the wire feeding rod 51 to slide again.The auxiliary reciprocating seat 2 sends the next group of wire harnesses to one side of the base 1. After the reciprocating seat 2 and the wire feeding rod 51 are reset, the C-shaped rod 6 abuts against the base 1, and through the inclined surface on the wedge block 61, the wedge block 61 descends and disengages from the push rod 81, so that the stretching mechanism 8 can continue to slide. After the wire harness is cut, the wire harness is sent to one side of the base 1, and then the worker detects and arranges the crimping part.

[0052] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
