[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0031] like Figures 1 to 10 As shown, an automatic wire threading device includes a workbench 1; a clamping mechanism 2, fixed on the workbench 1 for positioning and clamping a rubber sleeve 8; a sleeve feeding mechanism 3, connected above the clamping mechanism 2 and automatically releasing the rubber sleeve 8; a wire core feeding mechanism 4, close to the clamping mechanism 2 and threading the wire core 9 into the positioned rubber sleeve 8; a feeding mechanism 5, fixed on the clamping mechanism 2 and feeding out the wire after threading; a control system, connected to the clamping mechanism 2, the sleeve feeding mechanism 3, the wire core feeding mechanism 4, and the feeding mechanism 5 and controlling the operation of each mechanism.

[0032] The clamping mechanism 2 includes a positioning platform 21, two push plates 22 symmetrically arranged on the positioning platform 21, a plurality of suction cups 23 arranged in a row on the inner side of the push plates 22, and a V-shaped concave block 24 located between the two push plates 22 for guiding and supporting the rubber sleeve 8. The two push plates 22 are both connected to a propulsion cylinder 25 for driving each other to approach each other. When in use, since the material of the rubber sleeve 8 is relatively soft, in order to smoothly penetrate the wire core 9, the suction cup 23 can be used to prevent the rubber sleeve 8 from being flattened, and the rubber sleeve 8 can be clamped by the elasticity of the suction cup 23 itself.

[0033] The number of the suction cups 23 is three along the length direction of the push plate 22 .

[0034] The end of the clamping mechanism 2 away from the wire core feeding mechanism 4 is also provided with a support mechanism 6, which includes a support plate 61 rotatably connected to the positioning platform 21, a baffle 62 fixed to the support plate 61, and a hydraulic cylinder 63 with one end hingedly connected to the support plate 61 and the other end hingedly connected to the workbench 1. When in use, the right half of the rubber sleeve 8 is dragged by the support plate 61 to prevent it from turning over due to unstable center of gravity during the unloading process, and the baffle 62 prevents the rubber sleeve 8 from shifting under the action of inertia when falling, ensuring accurate positioning.

[0035] The sleeve feeding mechanism 3 includes a conical material box 31 with an open bottom, a guide plate 32 connected to the conical material box 31 and leaving a discharge port 3a between the guide plate 32 and the open top, a lever mechanism 33 close to the guide plate 32 and flipping to release the rubber sleeve 8, a photoelectric sensor 34 close to the lever mechanism 33, a slide rail 35 located at the rear side of the conical material box 31 and fixed on the workbench 1, a push plate 36 installed on the slide rail 35 and located in the discharge port 3a, and a hydraulic rod 37 connected to the push plate 36. When in use, the conical material box 31 adopts an open design, so that the rubber sleeve 8 in it can be pushed out by the push plate 36, the guide plate 32 and the discharge port 3a cooperate to realize the discharge of the rubber sleeve 8, and the photoelectric sensor 34 detects whether there is a workpiece at this position and replenishes the rubber sleeve 8 at this position in time.

[0036] The lever mechanism 33 is divided into two lever mechanisms 33 distributed in the upper and lower parts along the front end surface of the guide plate 32. The upper lever mechanism 33 is turned downward to discharge the material, and the lower lever mechanism 33 is turned upward to discharge the material. When in use, the rubber sleeve 8 is blocked twice to achieve stable and reliable output of the rubber sleeve 8, which is convenient for continuous feeding.

[0037] The lever mechanism 33 includes a rotating rod 331 installed on the conical material box 31, a plurality of paddles 332 evenly distributed on the rotating rod 331, a driving block 333 fixed on the rotating rod 331, and a cylinder 334 fixed on the conical material box 31 and having an output end that pushes the driving block 333 to rotate. When in use, the output end of the cylinder 334 extends out, contacts the driving block 333, and pushes the rotating rod 331 to rotate, thereby causing the paddle 332 to flip away from the material guide plate 32, so that the blocked rubber sleeve 8 falls down.

[0038] The wire core feeding mechanism 4 includes two moving blocks 41 horizontally slidably connected to the clamping mechanism 2, two rollers 42 for rotating the wire core 9, a driving mechanism 43 connected to the two rollers 42, and two positioning half blocks 44 that form a bell mouth with each other and are used to guide the wire core 9. The two rollers 42 and the two positioning half blocks 44 are respectively installed on the two moving blocks 41, and the two moving blocks 41 are connected to a driving cylinder 45 that pushes each other to approach each other. When in use, the wire core 9 first passes through the bell mouth formed by the two positioning half blocks 44 and gathers into a strand, then is squeezed out by the rotating rollers 42, and finally enters the rubber sleeve 8 for pipe threading. This method can ensure that the wire core 9 and the rubber sleeve 8 have sufficient installation clearance, which is more convenient to use.

[0039] The two rollers 42 are both made of PU material. The soft PU material is conducive to extruding the wire core 9 without damaging the wire core 9.

[0040] The driving mechanism 43 includes a driving motor 433, a first gear 431 coaxially connected to one of the two rollers 42, a second gear 432 coaxially connected to the other of the two rollers 42 and meshing with the first gear 431, and a synchronous belt transmission mechanism 434 whose two ends are respectively connected to the output shaft of the driving motor 433 and the first gear 431. When in use, the synchronous belt transmission mechanism 434 transmits the power of the driving motor 433 to the first gear 431, and meshes with the second gear 432 through the first gear 431, so that the two rollers 42 have opposite rotational motions, thereby providing power for threading the wire core 9.

[0041] The feeding mechanism 5 includes a long slide rail 51, a long cylinder 52 fixed on the long slide rail 51, a slider 53 that cooperates with the long slide rail 51 and is connected to the output end of the long cylinder 52, and an air claw 54 that is connected to the slider 53 and close to the rubber sleeve 8 in the clamping mechanism 2.

[0042] The control system includes a PLC, a human-machine interface and a relay connected to the PLC, and a solenoid valve connected to the relay. The PLC controls the relay to open, and then the relay controls each solenoid valve, thereby making the corresponding cylinders in each mechanism work, and the cylinders act on their respective actuators, the actuators include a clamping mechanism 2, a sleeve feeding mechanism 3, a wire core feeding mechanism 4, and a feeding mechanism 5. At the same time, the cylinders will also feed back the magnetic switch signal to the PLC, and the actuators will feed back to the PLC through the sensor signal, which is the photoelectric sensor 34 in the present invention, and the process of the PLC operation controls the lighting of each indicator light.

[0043] The method of using the present invention is further described below:

[0044] First, the rubber sleeve 8 is placed in the conical material box 31, and the hydraulic rod 37 drives the push plate 36 to move upward along the slide rail 35, pushing the rubber sleeve 8 out of the discharge port 3a and being blocked at the lever mechanism 33. After the No. 2 photoelectric sensor 34 detects that the rubber sleeve 8 is in place, the cylinder 334 is started and the rubber sleeve 8 falls onto the clamping mechanism 2.

[0045] At this time, the rubber sleeve 8 is initially positioned and restricted in the V-shaped recess 24, and the thrust cylinder 25 drives the two push plates 22 to approach each other, clamping the rubber sleeve 8 through the suction cup 23, while the support plate 61 of the support mechanism 6 drags the right half of the support plate 61.

[0046] The worker passes the multiple wire cores 9 through the bell mouth formed by the positioning half block 44, and the two rollers 42 rotate and extrude the multiple wire cores 9 under the action of the driving mechanism 43, and drive the wire cores 9 to move to the right and enter the rubber sleeve 8.

[0047] After the pipe threading is completed, the hydraulic cylinder 64 drags the support plate 61 to turn downward, the air claw 54 in the feeding mechanism 5 grabs the rubber sleeve 8, and the output end of the long cylinder 52 extends through the slider 53 to bring the rubber sleeve 8 out of the clamping mechanism 2. Repeat the above steps to cycle the wire threading.

[0048] In summary, the present invention can realize the loading, threading and feeding of rubber casings during wire production, reduce the manual participation process, reduce labor intensity, and improve work efficiency. The whole device has a high degree of automation, high accuracy in wire threading, low error rate, stable and reliable operation, is conducive to achieving continuous operation, reduces enterprise labor costs, and has significant economic benefits.
