[0004] When crimping, the device can align the wire harness with the terminal for easy docking. However, since the exposed wire cores of the wire harness after stripping will be scattered instead of gathered, even if the wire harness is aligned with the terminal, part of the wire core will be squeezed outside the terminal, causing a short circuit or other electrical problems, resulting in unstable crimping effect. Summary of the invention

[0005] The purpose of the present invention is to provide a processing device for automobile wiring harness terminals, which solves the problem that the wire core of the existing device cannot be fully inserted into the terminal, resulting in unstable crimping effect.

[0006] To achieve the above object, the present invention provides the following technical solution: a processing device for automobile wiring harness terminals, comprising a base, a hexagonal pressing assembly located above the base, and a first support plate and a second support plate located above the base, wherein the inner walls of the first support plate and the second support plate are sleeved with a ring, and further comprising:

[0007] The gathering component comprises a squeezing ring sleeved on the outer wall of the circular ring, the inner wall of the squeezing ring is in an inclined state, the inner wall of the squeezing ring is abutted against a plurality of squeezing rods, and a fourth squeezing block is installed on the side of the squeezing rod away from the squeezing ring and penetrating the circular ring; when the squeezing ring squeezes the squeezing rod, the fourth squeezing block squeezes and gathers the wire core of the wire;

[0008] The conveying assembly includes two fixed frames, an extrusion assembly and a rotating assembly. A plurality of clamping rods are rotatably installed on the inner walls of the two fixed frames. While the extrusion assembly drives the clamping rods to clamp and convey the wires, the rotating assembly drives the wires to rotate so that the wire cores completely enter the terminal.

[0009] Preferably, the gathering assembly further comprises two electric telescopic rods, which are symmetrically arranged on the outer wall of the first support plate, and the electric telescopic rods are installed on the outer wall of the extrusion ring at a side away from the first support plate.

[0010] Preferably, a spring is sleeved on the outer wall of the extrusion rod, and two ends of the spring are respectively mounted on the ring and the fourth extrusion block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a gathering component. When the electric telescopic rod is extended, the electric telescopic rod drives the extrusion ring to move on the circular ring. Since the inner wall of the extrusion ring is in an inclined state, the extrusion rod will be squeezed. The extrusion rod drives the fourth extrusion block to move toward the wire core and stretches the spring, so that the fourth extrusion block completes the gathering of the wire core. At this time, the fourth extrusion block no longer moves, and the electric telescopic rod continues to extend, and drives the circular ring to slide on the first support plate and the second support plate through the extrusion ring and the extrusion rod. The circular ring drives the round pin to move. Since the fourth extrusion block squeezes the wire core of the gathered wire at this time, the wire will move until the fourth extrusion block abuts against the hexagonal pressing assembly. At this time, the gathered wire core is inserted into the terminal to prevent the wire core from being squeezed outside the terminal.

[0020] The present invention is provided with a conveying component, the servo motor drives the gear to rotate, the gear drives the gear ring to rotate, the gear ring drives the circular ring to rotate, the circular ring drives the slide to rotate, the slide drives the fixed frame to rotate, the fixed frame drives the clamping rod to rotate, the clamping rod drives the wire to rotate slowly, and at the same time, the slide squeezes the first squeezing block. At this time, the slide moves toward one side of the terminal, the slide drives the fixed frame to move, the fixed frame drives the clamping rod to move, the clamping rod drives the wire to rotate and move at the same time, which can reduce the resistance of the wire core to move inside the terminal after deformation, so that the wire core is easier to insert into the terminal.

DETAILED DESCRIPTION

[0027] See also Figures 1 to 5 The present invention provides a technical solution: a processing device for automobile wiring harness terminals, comprising a base 1, a hexagonal pressing assembly 3 located above the base 1, and a first support plate 5 and a second support plate 8 located above the base 1, wherein the inner walls of the first support plate 5 and the second support plate 8 are sleeved with a ring 7, and further comprising:

[0028] The gathering component includes a squeeze ring 4 sleeved on the outer wall of the circular ring 7, the inner wall of the squeeze ring 4 is in an inclined state, and the inner wall of the squeeze ring 4 is abutted against a plurality of squeeze rods 18, and a fourth squeeze block 19 is installed on the side of the squeeze rod 18 away from the squeeze ring 4 and penetrating the circular ring 7; when the squeeze ring 4 squeezes the squeeze rod 18, the fourth squeeze block 19 squeezes and gathers the wire core of the wire 11;

[0029] The conveying assembly includes two fixed frames 22, an extrusion assembly and a rotating assembly. A plurality of clamping rods 23 are rotatably installed on the inner walls of the two fixed frames 22. While the extrusion assembly drives the clamping rods 23 to clamp and convey the wire 11, the rotating assembly drives the wire 11 to rotate so that the wire core completely enters the terminal 2.

[0030] Further, such as Figure 3 As shown, the gathering assembly further includes two electric telescopic rods 21, which are symmetrically arranged on the outer wall of the first support plate 5, and the electric telescopic rods 21 are installed on the outer wall of the extrusion ring 4 away from the first support plate 5;

[0031] The electric telescopic rod 21 extends or contracts to drive the extrusion ring 4 to move;

[0032] Further, such as Figure 3 As shown, the outer wall of the extrusion rod 18 is sleeved with a spring 20, and the two ends of the spring 20 are respectively mounted on the ring 7 and the fourth extrusion block 19;

[0033] When the extrusion rod 18 drives the fourth extrusion block 19 to move, the spring 20 is stretched, and when the spring 20 contracts, the extrusion rod 18 is driven to move through the fourth extrusion block 19;

[0034] Further, such as Figure 2 As shown, a plurality of slide plates 6 are installed on the outer wall of the fixed frame 22 through the ring 7;

[0035] Further, such as Figure 4 and Figure 5 As shown, the clamp rod 23 is made of metal, and the outer wall of the clamp rod 23 is covered with a rubber sleeve, the fixed frame 22 is equipped with an electromagnet 24 at the position corresponding to the clamp rod 23, and a torsion spring (not shown in the figure) is installed at the connection between the clamp rod 23 and the fixed frame 22;

[0036] When the electromagnet 24 is energized, the clamping rod 23 is attracted to rotate, so that the clamping rod 23 abuts against the fixed frame 22 and compresses the torsion spring. When the electromagnet 24 is not energized, the torsion spring stretches, driving the clamping rod 23 to rotate in the opposite direction.

[0037] Further, such as Figure 1 and Figure 2 As shown, the extrusion assembly includes a plurality of second extrusion blocks 14 fixedly mounted on the first support plate 5 and a first extrusion block 13 and a third extrusion block 15 fixedly mounted on the second support plate 8, wherein the first extrusion blocks 13 and the second extrusion blocks 14 are alternately arranged;

[0038] Further, such as Figure 2 As shown, a plurality of round pins 9 are installed on the outer wall of the circular ring 7;

[0039] Further, such as Figure 2 As shown, the rotating assembly includes a servo motor 17 mounted on the second support plate 8, the output shaft of the servo motor 17 is mounted with a gear 16, one side of the gear 16 is meshed with a gear ring 10, and the gear ring 10 is fixedly mounted on the outer wall of the ring 7;

[0040] The servo motor 17 rotates to drive the gear 16 to rotate, the gear 16 drives the gear ring 10 to rotate, and the gear ring 10 drives the ring 7 to rotate;

[0041] Furthermore, a pressure sensor (not shown in the figure) is installed inside the hexagonal pressing component 3 to detect pressure;

[0042] Further, such as Figure 1 As shown, a control panel 12 is installed on the outer wall of the base 1 for setting relevant parameters.

[0043] Working principle: Step 1, after the external power supply is connected, the electromagnet 24 is controlled to work through the control panel 12. At this time, the electromagnet 24 attracts the clamping rod 23, and the torsion spring between the clamping rod 23 and the fixed frame 22 is compressed. Then the stripped wire 11 is inserted into the ring 7 and extended from the fixed frame 22. When the stripped wire core of the wire 11 is in the fourth extrusion block 19, it stops. Then the control panel 12 controls the electromagnet 24 to stop working, and the compressed torsion spring is extended, driving the clamping rod 23 to abut against the outer wall of the wire 11. Since the outer wall of the clamping rod 23 has a rubber sleeve, the friction with the wire 11 is increased while the wire 11 is not damaged.

[0044] Step 2: put the terminal 2 into the hexagonal pressing component 3 (the hexagonal pressing component 3 is the prior art), and then use the control panel 12 to make the hexagonal pressing component 3 abut against the outer wall of the terminal 2, and stop when the pressure sensor detects a certain value, so that the terminal 2 is not squeezed and deformed, and remains fixed;

[0045] Step 3: Control the electric telescopic rod 21 to extend through the control panel 12, and the electric telescopic rod 21 drives the extrusion ring 4 to move on the circular ring 7. Since the inner wall of the extrusion ring 4 is in an inclined state, the extrusion rod 18 will be squeezed, and the extrusion rod 18 drives the fourth extrusion block 19 to move toward the wire core and stretch the spring 20 until the fourth extrusion block 19 completes the gathering of the wire core. At this time, the fourth extrusion block 19 no longer moves, and the electric telescopic rod 21 continues to extend, and the circular ring 7 will slide toward one side of the hexagonal pressing component 3 on the first support plate 5 and the second support plate 8 through the extrusion ring 4 and the extrusion rod 18. The circular ring 7 drives the round pin 9 to move. Since the fourth extrusion block 19 squeezes and gathers the wire core of the wire 11 at this time, the wire 11 will move until the fourth extrusion block 19 abuts against the hexagonal pressing component 3. At this time, the gathered wire core is inserted into the terminal 2, and then the electric telescopic rod 21 retracts back to the initial position, driving the extrusion ring 4 away from the extrusion rod 18. At this time, the spring 20 contracts, driving the fourth extrusion block 19 away from the wire core of the wire 11;

[0046] Step 4: Control the servo motor 17 to rotate through the control panel 12. First, the servo motor 17 drives the gear 16 to rotate 45 degrees, the gear 16 drives the gear ring 10 to rotate, the gear ring 10 drives the ring 7 to rotate, the ring 7 drives the slide plate 6 to rotate, the slide plate 6 drives the fixed frame 22 to rotate, the fixed frame 22 drives the clamping rod 23 to rotate, at this time, the fourth extrusion block 19 does not squeeze the wire core of the gathered wire 11, so the clamping rod 23 will drive the wire 11 to rotate slowly, at the same time, the round pin 9 will squeeze the third extrusion block 15, the round pin 9 drives the ring 7 to move away from the terminal 2, when the round pin 9 squeezes to the highest point of the third extrusion block 15, the ring 7 returns to the initial position, this When the slide plate 6 squeezes the first squeezing block 13 first, the slide plate 6 moves toward the terminal 2, the slide plate 6 drives the fixed frame 22 to move, the fixed frame 22 drives the clamping rod 23 to move, the clamping rod 23 drives the wire 11 to rotate and move at the same time, when the slide plate 6 squeezes to the highest point of the first squeezing block 13, the wire core of the wire 11 is completely inserted into the terminal 2, as the ring 7 continues to rotate 45 degrees, the slide plate 6 squeezes the second squeezing block 14, the slide plate 6 moves to the side away from the terminal 2, the slide plate 6 drives the fixed frame 22 to move, at this time the clamping rod 23 does not drive the wire 11 to move, when the slide plate 6 squeezes to the highest point of the second squeezing block 14, the fixed frame 22 returns to the initial position;

[0047] Step 5: When the ring 7 completes a 90-degree rotation, the core of the wire 11 is completely inserted into the terminal 2. At this time, the hexagonal pressing component 3 is controlled by the control panel 12 to crimp the terminal 2 and the wire 11. The pressure sensor detects the pressure to make the crimping pressure the optimal value. After the crimping is completed, the hexagonal pressing component 3 is controlled to open and the wire 11 can be pulled out from one side of the terminal 2.
