[0015] The beneficial effects of the present invention are as follows: 1. By providing the first clamping mechanism and the second clamping mechanism, when the wire harness of the terminal is transported to the placement groove by the transfer mechanism after being pressed by the pressing mechanism, the first clamping mechanism clamps and limits the terminal of the wire harness, and the second clamping mechanism clamps and limits the wire harness, avoiding the scattering of the wire harness and facilitating the collection by the staff; through the first extrusion plate and the first extrusion spring of the first clamping mechanism, the elastic force of the first extrusion spring facilitates the two first extrusion plates on both sides to tightly abut against both sides of the terminal to further limit it; through the telescopic plate of the second clamping mechanism, the second clamping plates are arranged on both sides of the telescopic plate, and the distance between the two second clamping plates can be adjusted to a certain extent according to the thickness of the wire harness, facilitating the two second clamping plates to abut against both sides of the wire harness.

When it is necessary to take out the wire harness from the collection groove, by adjusting the distance between the upper half clamping plate and the lower half clamping plate to a certain extent and cooperating with the retractable blocking mechanism arranged at the top of the upper half clamping plate, the collected wire harness can be squeezed in the vertical direction to further limit the movement of the wire harness and prevent it from moving out of the second clamping mechanism, facilitating the staff to take out the collected wire harness for subsequent processes.

[0016] 2. By providing the driving mechanism, the driving mechanism is used to drive the first clamping mechanism to reciprocate horizontally back and forth in the placement groove. When the terminal that has been press-fitted to the wire harness enters the first clamping mechanism and is clamped, the driving mechanism drives the first clamping mechanism to move forward.

When the driving mechanism drives the first clamping mechanism to move forward, the driving mechanism drives the two pushing mechanisms to approach each other through the transmission mechanism, and the two pushing mechanisms can push the two second clamping plates to approach each other, further clamping the wire harness in the horizontal direction, avoiding the entire wire harness from following the first clamping mechanism to move, and better screening out the terminals that are not firmly connected to the wire harness.

The conveying mechanism 1 is used to convey the wire harness without terminals to the pressing mechanism 2. The pressing mechanism 2 is used to press the terminals and the wire harness to make them fixedly connected. The transfer mechanism 3 is used to rotate the wire harness with the pressed terminals to the placement table 4. Those skilled in the art know that the wire harness and the terminals are pressed by the pressing mechanism 2. After pressing, the clamped arm on the transfer mechanism 3 continues to clamp the pressed wire harness. After clamping, the wire harness is placed in the collection groove for collection. In the present invention, when clamping the wire harness with the clamped arm, by setting a fixed displacement of the clamped arm for precise placement, however, the wire harness is placed in a messy manner. When it is necessary to package or organize the wire harness, it is not convenient to organize the wire harness. It is necessary to first organize the wire harness and then pick it up, which will greatly increase the workload.

[0021] In this embodiment, a placement groove 41 is provided on the top surface of the placement table 4. A first clamping mechanism 5 and a second clamping mechanism 6 are provided in the placement groove 41, and the first clamping mechanism 5 and the second clamping mechanism 6 are arranged in sequence along the length direction of the placement groove 41. A driving mechanism 7 is provided between the first clamping mechanism 5 and the placement groove 41. The driving mechanism 7 is used to drive the first clamping mechanism 5 to reciprocate horizontally back and forth in the placement groove 41. The second clamping mechanism 6 is detachably slidably connected to the placement groove 41; The first clamping mechanism 5 includes a first clamping plate 51. The first clamping plate 51 is a U-shaped plate with an open top and a closed bottom in cross-section. A plurality of first extrusion grooves 52 are opened on both sides inside the first clamping plate 51. A first extrusion plate 53 is slidably connected in the first extrusion groove 52. A first extrusion spring 54 is fixedly connected between the side of the first extrusion plate 53 close to the first extrusion groove 52 and the bottom surface inside the first extrusion groove 52; The second clamping mechanism 6 includes a telescopic plate 61 and a second clamping plate 62. The second clamping plate 62 is arranged on both sides of the telescopic plate 61. The telescopic plate 61 is detachably slidably connected to the placement groove 41. The second clamping plate 62 includes an upper half clamping plate 621 and a lower half clamping plate 622 arranged below the upper half clamping plate 621. The lower half clamping plate 622 is fixedly connected to both sides of the telescopic plate 61. Retractable blocking mechanisms 8 are provided at the tops of the two upper half clamping plates 621. When the two blocking mechanisms 8 extend and approach each other, they can block the wire harness from entering and leaving the second clamping mechanism 6. When the two blocking mechanisms 8 retract and move away from each other, they can allow the wire harness to enter and leave the second clamping mechanism 6; An adjustment support mechanism 9 is provided between the upper clamping plate 621 and the lower clamping plate 622. The adjustment support mechanism 9 is used to connect the upper clamping plate 621 and the lower clamping plate 622 and can adjust the distance between the upper clamping plate 621 and the lower clamping plate 622. The adjustment support mechanism 9 includes a connecting telescopic rod 91, a connecting spring 92 and a clamping mechanism. A connecting port 6221 is formed on the top surface of the lower clamping plate 622. The connecting telescopic rod 91 is arranged inside the connecting port 6221. One end of the connecting telescopic rod 91 is fixedly connected to the bottom surface of the upper clamping plate 621. The connecting spring 92 is arranged outside the connecting telescopic rod 91. Both ends of the connecting spring 92 are fixedly connected to the bottom surface of the upper clamping plate 621 and the inner bottom surface of the connecting port 6221 respectively. The clamping mechanism is arranged between the upper clamping plate 621 and the lower clamping plate 622.

[0022] Through the provided first clamping mechanism 5 and second clamping mechanism 6, when the wire harness of the terminal is transported to the placement groove 41 by the pressing mechanism 2 and then transported by the transfer mechanism 3, the first clamping mechanism 5 clamps and limits the terminal of the wire harness, and the second clamping mechanism 6 clamps and limits the wire harness, avoiding the scattering of the wire harness and facilitating the collection by the staff; through the first pressing plate 53 and the first pressing spring 54 of the first clamping mechanism 5, the elastic force of the first pressing spring 54 facilitates the two first pressing plates 53 on both sides to tightly abut against both sides of the terminal for further limiting; through the telescopic plate 61 of the second clamping mechanism 6, the second clamping plates 62 are arranged on both sides of the telescopic plate 61, and the distance between the two second clamping plates 62 can be adjusted to a certain extent according to the thickness of the wire harness, facilitating the two second clamping plates 62 to abut against both sides of the wire harness. The second clamping plate 62 includes an upper clamping plate 621 and a lower clamping plate 622, and an adjustment support mechanism 9 is provided between them. The adjustment support mechanism 9 is used to connect the upper clamping plate 621 and the lower clamping plate 622 and can adjust the distance between the upper clamping plate 621 and the lower clamping plate 622. When the wire harness needs to be taken out from the collection groove, by adjusting the distance between the upper clamping plate 621 and the lower clamping plate 622 to a certain extent and cooperating with the retractable blocking mechanism 8 provided at the top of the upper clamping plate 621, the collected wire harness can be squeezed in the vertical direction, further limiting the movement of the wire harness and preventing it from moving out of the second clamping mechanism 6, facilitating the staff to take out the collected wire harness for subsequent processes.

[0023] Moreover, in this embodiment, the engaging mechanism includes a clamping block 93, a clamping inclined block 94 and a jacking block 95. The clamping block 93 is fixedly connected to the bottom surface of the upper clamping plate 621, and an installation opening 931 for slidably connecting with the clamping inclined block 94 is formed on one side of the clamping block 93. A lifting spring 932 is fixedly connected to the bottom surface inside the installation opening 931, and the other end of the lifting spring 932 is fixedly connected to the clamping inclined block 94. A clamping opening 6222 matching with the clamping block 93 is formed on the top surface of the lower clamping plate 622, and a top opening 6223 fitting with the clamping inclined block 94 is formed on one side of the clamping opening 6222. The jacking block 95 is slidably connected inside the top opening 6223.

[0024] Through the provided engaging mechanism, when it is necessary to reduce the distance between the upper clamping plate 621 and the lower clamping plate 622, the upper clamping plate 621 and the lower clamping plate 622 approach each other, causing the connecting telescopic rod 91 and the connecting spring 92 to contract, so that the clamping block 93 enters the inside of the clamping opening 6222. At the same time, under the elongation action of the lifting spring 932, the clamping inclined block 94 enters the inside of the top opening 6223 to jack up the jacking block 95, and then the distance between the upper clamping plate 621 and the lower clamping plate 622 can be reduced. When the jacking block 95 is pressed, the lifting spring 932 contracts and the clamping inclined block 94 disengages from the top opening 6223. With the reset action of the connecting spring 92, the distance between the upper clamping plate 621 and the lower clamping plate 622 increases again.

[0025] Meanwhile, in this embodiment, the blocking mechanism 8 includes a blocking inclined block 81, a blocking spring and a limiting block 82. Blocking openings 6211 are formed on the mutually approaching side surfaces of the two upper clamping plates 621, and limiting openings 6212 communicating with the blocking openings 6211 are formed on both sides of the top surface of the upper clamping plate 621. The blocking inclined block 81 is slidably connected inside the blocking opening 6211. The two ends of the blocking spring are respectively fixedly connected to the side surface of the blocking inclined block 81 and the bottom surface inside the blocking opening 6211. A sliding opening 811 is formed on the top surface of the blocking inclined block 81, and the limiting block 82 is slidably connected inside the sliding opening 811. The limiting block 82 is adapted to the limiting opening 6212, and a return spring is arranged between the limiting block 82 and the sliding opening 811.

[0026] Through the provided blocking mechanism 8, when it is necessary for the wire harness to enter the second clamping mechanism 6, the limiting block 82 is pressed, and the limiting block 82 slides into the sliding opening 811. At the same time, the blocking inclined block 81 is pushed to move in the mutually away direction until the limiting block 82 moves below another limiting opening 6212. Under the action of the return spring, the limiting block 82 is clamped into the limiting opening 6212 to fix the blocking inclined block 81. At this time, the distance between the two blocking inclined blocks 81 allows the wire harness to pass through, and the inclined surface of the blocking inclined block 81 plays a certain guiding role for the wire harness, facilitating the wire harness to enter the second clamping mechanism 6.

[0027] Moreover, in this embodiment, the telescopic plate 61 includes an intermediate plate 611. Six telescopic springs 6111 are symmetrically and fixedly connected inside the intermediate plate 611. Three telescopic springs 6111 on the same side are jointly fixedly connected to a movable plate 612, and the movable plate 612 is slidably connected to the intermediate plate 611.

[0028] Through the provided telescopic plate 61, the sliding connection between the two movable plates 612 and the intermediate plate 611, and the provided telescopic springs 6111, it is convenient to adjust the distance between the two second clamping plates 62 according to the thickness of the wire harness, so that the two second clamping plates 62 abut against both ends of the wire harness.

[0029] In addition, in this embodiment, a chute 411 penetrating the placement groove 41 is opened on the rear side of the inner bottom surface of the placement groove 41. A slider 412 is slidably connected in the chute 411, and the top surface of the slider 412 is fixedly connected to the bottom surface of the intermediate plate 611 of the telescopic plate 61.

[0030] Through the provided chute 411 and slider 412, with the slider 412 slidably connected in the chute 411, the slider 412 can drive the telescopic plate 61 fixedly connected above it to slide, thereby driving the second clamping mechanism 6 and the wire harness placed in the second clamping mechanism 6 to move. When the staff needs to remove the wire harness from the placement groove 41, they only need to grasp the second clamping mechanism 6 and slide it backward until the slider 412 slides out of the chute 411, then they can take out the collected and sorted wire harness, which is convenient for subsequent processes.

[0031] In addition, in this embodiment, the driving mechanism 7 includes a motor 71, a lead screw 72, and a moving block 73. An installation cavity is provided inside the placement table 4, and a lead screw 72 is rotatably provided in the installation cavity. A motor 71 is fixedly connected to one side of the placement table 4, and the output end of the motor 71 penetrates the placement table 4 and is fixedly connected to the lead screw 72 in the installation cavity. A moving groove 413 is opened on the front side of the inner bottom surface of the placement groove 41, and the moving groove 413 communicates with the installation cavity. A moving block 73 is slidably connected in the moving groove 413, and the moving block 73 is threadedly connected to the lead screw 72. The top surface of the moving block 73 is fixedly connected to the bottom surface of the first clamping plate 51.

[0032] Through the provided driving mechanism 7, the motor 71 drives the lead screw 72 to rotate. The rotation of the lead screw 72 drives the moving block 73 to move. The movement of the moving block 73 can drive the first clamping mechanism 5 to move. The first clamping mechanism 5 reciprocates horizontally back and forth in the placement groove 41. When the terminal that has been press-fitted and connected to the wire harness enters the first clamping mechanism 5 and is clamped, the driving mechanism 7 drives the first clamping mechanism 5 to move forward. When the terminal is not tightly press-fitted and connected to the wire harness, the terminal will move forward with the first clamping mechanism 5 and thus separate from the wire harness. In this way, it is used to screen out the unqualified wire harnesses after pressing, which is convenient for the staff to select and press again.

[0033] Moreover, in this embodiment, pushing mechanisms 10 are provided on both sides of the second clamping mechanism 6. The pushing mechanisms 10 are used to push the two second clamping plates 62 closer to each other. A transmission mechanism is provided between the two pushing mechanisms 10 and the driving mechanism 7. The driving mechanism 7 drives the reciprocating movement of the pushing mechanisms 10 to move closer to and away from each other through the transmission mechanism.

[0034] Through the provided transmission mechanism and the pushing mechanisms 10, the driving mechanism 7 drives the reciprocating movement of the pushing mechanisms 10 to move closer to and away from each other through the transmission mechanism. When the driving mechanism 7 drives the first clamping mechanism 5 to move forward, the driving mechanism 7 drives the two pushing mechanisms 10 closer to each other through the transmission mechanism. The two pushing mechanisms 10 can then push the two second clamping plates 62 closer to each other, further clamping the wire harness in the horizontal direction, preventing the entire wire harness from moving with the first clamping mechanism 5, and better screening out the terminals that are not firmly connected to the wire harness.

[0035] And, in this embodiment, the transmission mechanism includes a gear 11, a rack 12, and a top block 13. A transmission cavity communicating with the installation cavity is formed inside the placement table 4. One end of the lead screw 72 penetrates through the installation cavity and extends into the transmission cavity to be fixedly connected to a connecting rod 14, and the connecting rod 14 is rotatably connected to the transmission cavity. A gear 11 is fixedly connected to the outside of the connecting rod 14 and inside the transmission cavity. Two racks 12 are slidably connected to both side surfaces inside the transmission cavity, and both racks 12 are engaged with the gear 11. A top block 13 is fixedly connected between the top surfaces of the two racks 12. Accommodating grooves 131 are formed in the lower parts of both side surfaces of the top block 13. The pushing mechanisms 10 are arranged on both sides of the top block 13. When the top block 13 is driven to rise by the gear 11 and the rack 12, the pushing mechanisms 10 can be inserted into the accommodating grooves 131, causing the pushing mechanisms 10 to move in the direction of approaching each other. When the top block 13 is driven to descend by the gear 11 and the rack 12, the pushing mechanisms 10 are removed from the accommodating grooves 131, causing the pushing mechanisms 10 to move in the direction of moving away from each other.

[0036] Through the provided transmission mechanism, the rotation of the lead screw 72 drives the rotation of the connecting rod 14. The rotation of the connecting rod 14 drives the rotation of the gear 11. The rotation of the gear 11 drives the two racks 12 engaged with it to move upward, thereby displacing the top block 13 upward. When the top block 13 is driven to rise by the gear 11 and the rack 12, the pushing mechanisms 10 can be inserted into the accommodating grooves 131, causing the pushing mechanisms 10 to move in the direction of approaching each other, and further clamping the two second clamping plates 62 closer to each other to further clamp the wire harness. When the top block 13 is driven to descend by the gear 11 and the rack 12, the pushing mechanisms 10 are removed from the accommodating grooves 131, causing the pushing mechanisms 10 to move in the direction of moving away from each other.

[0037] Meanwhile, in this embodiment, the pushing mechanism 10 includes a push rod 101, a limiting spring 102, and a push plate 103. The push rod 101 is L-shaped. Pushing grooves 414 are correspondingly formed on both sides of the bottom surface inside the placement groove 41 for the push rod 101. The push rod 101 is slidably connected in the pushing grooves 414. A connecting groove communicating the pushing grooves 414 and the transmission cavity is provided inside the placement table 4. The push rod 101 is arranged in the connecting groove. One end of the push rod 101 penetrates through the pushing groove 414 and extends into the placement groove 41 to be fixedly connected to the push plate 103. The other end of the push rod 101 penetrates through the connecting groove and extends into the transmission cavity to abut against the top block 13. The limiting spring 102 is sleeved on the outer side of the push rod 101. One end of the limiting spring 102 is fixedly connected to the inner wall of the connecting groove, and the other end of the limiting spring 102 is fixedly connected to the side surface of the push rod 101 close to the transmission cavity.

[0038] With the pushing mechanism 10 provided, when the top block 13 is driven to rise by the gear 11 and the rack 12, until the receiving groove 131 moves to one side of the push rod 101, under the action of the limiting spring 102, one section of the push rod 101 is clamped into the receiving groove 131, so that the two push rods 101 are displaced in the direction of approaching each other. Through the pushing grooves 414 formed on the bottom surface of the placement groove 41, the push rod 101 moves in the pushing grooves 414, so that the push plate 103 further pushes the two second clamping plates 62 to move in the direction of approaching each other. When the top block 13 is driven to descend by the gear 11 and the rack 12, the push rod 101 moves out of the receiving groove 131, causing the pushing mechanism 10 to move in the direction of moving away from each other, and the two second clamping plates 62 move in the direction of moving away from each other.

[0039] In addition, a plurality of second extrusion grooves are formed on the mutually approaching side surfaces of the two upper half clamping plates 621 and the mutually approaching side surfaces of the two lower half clamping plates 622. Second extrusion plates 63 are slidably connected in the second extrusion grooves. A second extrusion spring is fixedly connected between the side surface of the second extrusion plate 63 close to the second extrusion groove and the bottom surface inside the second extrusion groove.

[0040] With the second extrusion plates 63 provided, the elastic force of the second extrusion springs facilitates the two second extrusion plates 63 on both sides to tightly abut against both sides of the wire harness to further limit it.

[0041] During use, the conveying mechanism 1 is used to convey the wire harness without terminals to the crimping mechanism 2. The crimping mechanism 2 is used to crimp the terminals and the wire harness to make them fixedly connected. After the wire harness and the terminals are crimped by the crimping mechanism 2, the clamping arm on the transfer mechanism 3 continues to clamp the crimped wire harness. After clamping the wire harness with the clamping arm, a fixed displacement is set for the clamping arm, and it is accurately placed into the first clamping mechanism 5 and the second clamping mechanism 6 in the placement groove 41. The elastic force of the first compression spring 54 facilitates the tight abutment of the first pressing plates 53 on both sides against both sides of the terminal to further limit it. Through the telescopic plate 61 of the second clamping mechanism 6, the second clamping plates 62 are arranged on both sides of the telescopic plate 61, and the distance between the two second clamping plates 62 is adjusted according to the thickness of the wire harness, so that the two second clamping plates 62 abut against both sides of the wire harness, and the elastic force of the second compression spring facilitates the tight abutment of the second pressing plates 63 on both sides against both sides of the wire harness to further limit it. When the wire harness collection is completed, the motor 71 drives the lead screw 72 to rotate. The rotation of the lead screw 72 drives the moving block 73 to move. The movement of the moving block 73 can drive the first clamping mechanism 5 to move. The first clamping mechanism 5 moves horizontally back and forth in the placement groove 41. When the terminals that have been crimped and connected to the wire harness enter the first clamping mechanism 5 and are clamped, the driving mechanism 7 drives the first clamping mechanism 5 to move forward. When the terminals are not tightly crimped and connected to the wire harness, the terminals will move forward with the first clamping mechanism 5, thus separating from the wire harness, so as to screen out the unqualified crimped wire harnesses. At the same time, the rotation of the lead screw 72 drives the connecting rod 14 to rotate. The rotation of the connecting rod 14 drives the gear 11 to rotate. The rotation of the gear 11 drives the two racks 12 engaged with it to move upward, thereby displacing the top block 13 upward. When the top block 13 is driven to rise through the gear 11 and the rack 12, until the receiving groove 131 moves to one side of the push rod 101, under the action of the limiting spring 102, one end of the push rod 101 is snapped into the receiving groove 131, so that the two push rods 101 are displaced in the direction of approaching each other. Through the push groove 414 opened on the bottom surface of the placement groove 41, the push rod 101 moves in the push groove 414, so that the push plate 103 further pushes the two second clamping plates 62 to move in the direction of approaching each other, and further clamps the wire harness in the horizontal direction to prevent the entire wire harness from moving with the first clamping mechanism 5.After the screening is completed, when the top block 13 is driven to descend by the gear 11 and the rack 12, the push rod 101 moves out of the receiving groove 131, causing the pushing mechanism 10 to move in a direction away from each other, which makes the two second clamping plates 62 move in a direction away from each other, pressing the limiting block 82, and the limiting block 82 slides into the sliding opening 811. At the same time, the blocking inclined block 81 is pulled out and moves in a direction close to each other until the limiting block 82 moves below another limiting opening 6212. Under the action of the return spring, the limiting block 82 is snapped into the limiting opening 6212 to fix the blocking inclined block 81. At this time, the distance between the two blocking inclined blocks 81 prevents the wire harness from passing through. Then, when the distance between the upper half clamping plate 621 and the lower half clamping plate 622 is reduced, the upper half clamping plate 621 and the lower half clamping plate 622 approach each other, causing the connecting telescopic rod 91 and the connecting spring 92 to contract, so that the clamping block 93 enters the inside of the clamping interface 6222. At the same time, under the elongation action of the lifting spring 932, the clamping inclined block 94 enters the inside of the top opening 6223 to lift the lifting block 95, so that the distance between the upper half clamping plate 621 and the lower half clamping plate 622 can be reduced. Grab the second clamping mechanism 6 and slide backward until the slider 412 slides out of the sliding groove 411, and the wire harness that has been collected and sorted can be taken out, which is convenient for subsequent processes.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
