For example, they can mean fixed connection, detachable connection, or integral connection; they can mean mechanical connection or electrical connection; they can mean direct connection, indirect connection through an intermediate medium, or internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figure 1 As shown, the present invention provides a wire conveying device for feeding long and short wires of a shell threading machine, which includes a substrate 1, a front-end lead mechanism 4, a wire pressing mechanism 5, a rear-end lead mechanism 6, a retracting mechanism 7 and a wire clamping mechanism 8. The substrate 1 is provided with a first wire transition piece 2 and a second wire transition piece 3; the front-end lead mechanism 4 is arranged at the front end of the substrate 1; the wire pressing mechanism 5 is mounted on the substrate 1, and the wire pressing mechanism 5 is arranged corresponding to the first wire transition piece 2; the rear-end lead mechanism 6 is installed at the rear end of the substrate 1; the retracting mechanism 7 is arranged at the side end of the substrate 1; the wire clamping mechanism 8 is arranged corresponding to the rear-end lead mechanism 6, and the wire clamping mechanism 8 is controlled by the retracting mechanism 7.

[0049] The present invention is used to fix and transfer cables. The cables are first sent to the stripping mechanism for end stripping, and then the cables are sent to the plastic shell structure for pressing the plastic shell. After that, the length of the cables is adjusted to facilitate subsequent cutting. Specifically, the cables are first passed through the rear lead mechanism 6, the first wire transition device 2, the second wire transition device 3 and the front lead mechanism 4 in sequence. During the cable stripping, plastic shell application and cutting process, the wire pressing mechanism 5 presses and fixes the cables. In the stripping and plastic shell application process, the length of the cables is uniform, in order to meet the needs of long and short cables. In order to meet the demand, before cutting, the wire pressing mechanism 5 needs to loosen the cable, and then the retreat mechanism 7 drives the wire clamping mechanism 8, which drags part of the cable backward for a distance, and can form finished products of different lengths after cutting; the present invention uses multiple mechanisms to coordinate to complete the fixation of the cable, and can meet people's needs for long and short cables in the same batch, overcoming the defect that the existing equipment can only process cables of a single length. The device has a high degree of automation and can replace manual labor to complete the processing needs of long and short cables, which can not only improve the processing efficiency, but also reduce the labor intensity of workers.

[0050] Reference Figure 2 In a specific example of the present invention, the wire pressing mechanism 5 includes a stand 501 mounted on a base plate 1, and a wire pressing cylinder 502 is installed on the stand 501; a limit block 503 is also provided on the stand 501, and the limit block 503 is placed directly below the wire pressing cylinder 502, and a wire pressing plate 504 is installed in the limit block 503, and the wire pressing plate 504 is connected to the piston end of the wire pressing cylinder 502; the wire pressing plate 504 is placed directly above the first wire transition device 2.

[0051] The wire pressing mechanism 5 of the present invention is mainly used to fix the cable during the cable processing process to avoid the cable from being pulled, bent, etc. and affecting the processing quality. Specifically, the limit block 503 limits the wire pressing plate 504 to ensure that the wire pressing plate 504 always moves in the vertical direction. When the wire needs to be pressed, the wire pressing cylinder 502 is actuated to lower the wire pressing plate 504, so that the wire pressing plate 504 contacts the first wire transition device 2 and tightens the cable. The adoption of this solution can ensure the quality of processing and improve the quality of the finished product.

[0052] Reference Figure 2 In a specific example of the present invention, the rear-end lead mechanism 6 includes a first bracket 601, which is extended and installed on the rear end of the substrate 1; the first bracket 601 extends out of the substrate 1 and is provided with a first lead module 602 and a second lead module 603 at one end, wherein the second lead module 603 is placed between the first lead module 602 and the substrate 1; the rear-end lead mechanism 6 also includes a lead roller 604, which is placed between the second lead module 603 and the substrate 1; the first wire transition 2, the second wire transition 3, the first lead module 602, the second lead module 603 and the lead roller 604 are all on the same plane.

[0053] The function of the rear-end lead mechanism 6 of the present invention is to straighten the cable before entering the first wire transition device 2. Specifically, one end of the cable passes through the first lead module 602, the second lead module 603 and the lead roller 604 in sequence and then connects to the first wire transition device 2. This mechanism can ensure that the cable processing accuracy can meet people's needs, such as reducing the error of the length after cutting and improving the quality of the finished product.

[0054] Reference Figure 3 and Figure 4In a specific example of the present invention, the retreat mechanism 7 includes a support block 701 arranged at the side end of the substrate 1, and a second bracket 702 is installed on the support block 701; a linear guide rail 704 is provided on the second bracket 702, and a guide rail slider 705 is slidably installed on the linear guide rail 704, and a push plate 706 is provided on the guide rail slider 705; a retreat cylinder 703 is provided on the second bracket 702, and the piston end of the retreat cylinder 703 is connected to the push plate 706; a buffer block 708 is also provided on the second bracket 702, and an anti-collision block 707 is provided on the side of the push plate 706 away from the retreat cylinder 703, and the anti-collision block 707 is arranged opposite to the buffer block 708.

[0055] The retraction mechanism 7 of the present invention is designed to meet the demand of processing long and short wires in the same batch at the same time. It is mainly for the action of the retraction cylinder 703. The piston end of the retraction cylinder 703 extends to push the push plate 706 backward, and the push plate 706 drives the wire clamping mechanism 8 to move backward and then drags part of the cable backward to shorten. After cutting, finished cables of different lengths can be obtained. The anti-collision block 707 and the buffer block 708 prevent the push plate 706 from moving too much and affecting the normal operation of the wire clamping mechanism 8.

[0056] Reference Figure 4 and Figure 5 In a specific example of the present invention, the wire clamping mechanism 8 includes a connecting bar 801, which is connected to the push plate 706; a mounting plate 802 is provided on the connecting bar 801, and the mounting plate 802 is placed below the second bracket 702; a wire clamping cylinder 803 is provided on one end face of the mounting plate 802, and a hinged workpiece 804 is provided on the other end face, and the hinged workpiece 804 is provided with a mounting groove 805, and a follower block 807 is provided in the mounting groove 805, and the follower block 807 is connected to the piston end of the wire clamping cylinder 803; a clamping component 806 is also provided in the mounting groove 805, and the clamping component 806 is controlled by the follower block 807.

[0057] The wire clamping mechanism 8 of the present invention follows the retreat mechanism 7. During the retreat of the push plate 706, the mounting plate 802 is driven to retreat through the connecting bar 801. Before retreating, the wire clamping cylinder 803 is actuated first, and the piston end of the wire clamping cylinder 803 is pushed out, driving the clamping component 806 to clamp part of the cable through the follower block 807. When the clamping component 806 clamps the cable, the push plate 706 starts to retreat.

[0058] Reference Figure 5 and Figure 6In a specific example of the present invention, the clamping component 806 includes an upper hinge arm 8061 and a lower hinge arm 8062, and the upper hinge arm 8061 and the lower hinge arm 8062 are both rotatably mounted in the mounting groove 805 of the hinged workpiece 804, and the upper hinge arm 8061 and the lower hinge arm 8062 are symmetrically arranged; one end of the upper hinge arm 8061 is hinged to an upper hinge bar 8063, and the upper hinge bar 8063 is hingedly connected to the follower block 807; one end of the lower hinge arm 8062 is hinged to a lower hinge bar 8064, and the lower hinge bar 8064 is hinged to the follower block 807 is hingedly connected; the other end of the upper hinged arm 8061 is provided with an upper clamping line 8065, and the other end of the lower hinged arm 8062 is provided with a lower clamping line 8066, and the upper clamping line 8065 and the lower clamping line 8066 are arranged corresponding to each other; the upper clamping line 8065 and the lower clamping line 8066 are both placed between the first lead module 602 and the second lead module 603; a plurality of avoidance slots 8067 are opened on the upper clamping line 8065 and the lower clamping line 8066, and a tooth-shaped clamping portion 8068 is formed between two adjacent avoidance slots 8067.

[0059] The clamping member 806 of the present invention is controlled by the clamping cylinder 803. Since the upper and lower articulated arms are respectively hinged by the upper and lower articulated bars, when the piston end of the clamping cylinder 803 is extended, the follower block 807 moves backward. Through the action of the connecting rod formed by the articulated bar and the articulated arm, the upper clamping line 8065 and the lower clamping line 8066 are brought close to each other to clamp the cable, and vice versa, the cable is released. In addition, since a plurality of avoidance slots 8067 are provided on the upper clamping line 8065 and the lower clamping line 8066, the avoidance slots 8067 of the two adjacent ones are close to each other. A toothed clamping portion 8068 is formed therebetween. When the upper clamping line 8065 and the lower clamping line 8066 are close to each other, the cable that falls into the avoidance slot 8067 is in its original position, and the cable in the toothed clamping portion 8068 is clamped and at the same time pulled backward for a distance under the action of the retreat mechanism 7. When cutting, the length of the cable pulled backward is shorter, and the length of the cable in the original position is longer. Therefore, the simultaneous processing requirements of cables of different lengths can be completed in the same batch, overcoming the defect that the existing equipment can only process cables of a single length.
