Description

Technical Field

[0001] The invention relates to the technical field of automobile wire harness processing, and in particular to an automatic stripping device for automobile wire harnesses. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., and the wiring harness is bundled to form a component connecting the circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and is generally H-shaped. Stripping the wire harness is an important step in the electronic manufacturing process. The outer insulating material of the wire is stripped off to expose the conductor and better connect it to the terminal.

[0003] In the prior art, when stripping the ends of automobile wire harnesses, a wire stripping machine is usually used to remove the outer insulation layer of the wire harness. The wire stripping machine can efficiently complete the wire stripping work. Although the existing wire stripping machine can automatically remove the insulating rubber layer at the ends of the wire harness without manual work, it is still necessary to manually feed the ends of the wire harness into the cutting knife part of the wire stripping machine. When stripping multiple wire harnesses, manual labor frequently repeats the work of taking and feeding the wire harnesses, which makes the hands more tired. After working for a long time, the efficiency of manual wire harness taking and feeding is greatly reduced, which is easy to cause production accidents and cannot guarantee the safety of the staff.

[0018] 2. In the present invention, since a plurality of conveyor racks are arranged on the outer wall of the first conveyor belt, when the wire harness body inside the front conveyor rack is subjected to stripping processing, both ends of the wire harness body inside the rear conveyor rack are clamped by two sets of corresponding arc-shaped rotating plates, so that the cleaning pads arranged on the outer wall close to one side of the two sets of arc-shaped rotating plates are in contact with the part to be stripped at the end of the wire harness body, and the two second sliders are moved back and forth inside the second slide groove, thereby driving the wire harness body clamped and fixed by the two sets of clamps to move back and forth inside the conveyor rack, so that during the friction between the two ends of the wire harness body and the two sets of cleaning pads, the debris on the outer walls at both ends are automatically cleaned and removed, so as to avoid carrying the debris into the stripping mechanism and causing contamination to the wire harness body after the subsequent stripping processing.

With the help of the two industrial cameras, the exposed parts of the wire core after the stripping treatment at the end of the wiring harness body can be visually identified and inspected to detect whether the stripping process at the end of the wiring harness body is qualified.

[0040] As a technical optimization scheme of the present invention, the outer wall of the side where the two moving plates 18 are close to each other is provided with a third slot 22, and the inside of the two third slots 22 is symmetrically installed with a third slider 24, and the ends of the two third sliders 24 away from the third slot 22 are connected to the clamping plate 19 for clamping and fixing the wiring harness body 17 through the third electric telescopic rod 25.

[0041] As a technical optimization solution of the present invention, the processing mechanism includes a fourth slide groove 26 opened on the inner wall of both sides of the conveying frame 5, and a fourth slider 27 is installed inside the two fourth slide grooves 26, and a rectangular plate 28 is commonly connected between the two fourth sliders 27. A third linear motor is preset inside the two fourth slide grooves 26, and the two third linear motors can respectively drive the corresponding fourth slider 27 to move back and forth inside the corresponding fourth slide groove 26, and drive the rectangular plate 28 to move back and forth.

[0042] As a technical optimization solution of the present invention, a lifting seat 31 is arranged directly above the rectangular plate 28, and a double-headed screw 29 is commonly installed at one end of the two fourth sliding blocks 27 away from the fourth sliding groove 26. Two moving blocks 32 are symmetrically installed on the outer wall of the double-headed screw 29, and the tops of the two moving blocks 32 and the bottom of the lifting seat 31 are symmetrically hinged with rotating blocks 33, and the two matching rotating blocks 33 are connected and fixed by two fourth electric telescopic rods 30. A second driving device is preset inside one of the fourth sliding blocks 27, and the output end of the second driving device is connected to one end of the double-headed screw 29, so that the double-headed screw 29 can be driven to rotate, so that the two moving blocks 32 can move in a direction close to or away from each other; when the two moving blocks 32 move in a direction close to each other, they can drive the two groups of corresponding rotating blocks 33 to rotate in a direction close to each other, and push the lifting seat 31 to move in a direction away from the rectangular plate 28, and can drive the lifting seat 31 to move a greater distance with the help of the extension of the telescopic end of the fourth electric telescopic rod 30; the two moving blocks 32 move in a direction away from each other, drive the two groups of corresponding rotating blocks 33 to rotate in a direction away from each other, and pull the lifting seat 31 to move in a direction close to the rectangular plate 28.

[0043] As a technical optimization solution of the present invention, two arc-shaped rotating plates 20 are symmetrically hinged on the top of the lifting seat 31, and the outer walls of the two arc-shaped rotating plates 20 close to each other are provided with arc-shaped grooves 34, and the insides of the two arc-shaped grooves 34 are installed with electric sliders 36, and the ends of the two electric sliders 36 away from the arc-shaped grooves 34 are installed with arc-shaped connecting plates, and the outer walls of the two arc-shaped connecting plates close to each other are installed with semicircular cleaning pads 37. Two third driving devices are preset on the outer wall of one side of the lifting seat 31, and the output ends of the two third driving devices are respectively connected to the hinged parts of the two arc-shaped rotating plates 20, so as to drive the two arc-shaped rotating plates 20 to rotate and adjust; the two electric sliders 36 move inside the corresponding arc-shaped grooves 34, and drive the arc-shaped connecting plates and the cleaning pads 37 to move and adjust.

[0044] As a technical optimization solution of the present invention, both arc-shaped rotating plates 20 are hollow, and the outer walls of the two arc-shaped rotating plates 20 on the side close to each other are provided with multiple air outlets 35. The outer walls of both sides of the two arc-shaped rotating plates 20 can be connected to the output end of the external preset hot air blower through a hose, so that the hot air generated by the external hot air blower is transported to the inside of the two arc-shaped rotating plates 20 through the hose, and discharged outward from the multiple air outlets 35, which has a softening effect on the end of the wire harness body 17 to be stripped, making it easier for the subsequent stripping mechanism to strip the end of the wire harness body 17; the cleaning pad 37 is made of sponge material, so that it will not block the air outlet 35.

[0045] As a technical optimization solution of the present invention, rectangular blocks 6 are installed on both sides of the outer wall of the fixing frame 1, and industrial cameras 7 for detecting the wire harness body 17 after the end stripping treatment are installed on the outer wall of the two rectangular blocks 6. Both industrial cameras 7 are ACA4112-8GC industrial cameras in the prior art, which are convenient for detecting the end of the wire harness body 17 after the stripping treatment to detect whether the stripping treatment of the end of the wire harness body 17 is qualified.

[0046] In the present invention, when the user uses the device, a loading robot or a staff is preset at the right end of the fixed frame 1. As the first conveyor belt 2 drives the multiple conveyor frames 5 arranged on its outer wall to rotate counterclockwise toward the left end, multiple wire harness bodies 17 to be stripped are placed in turn inside the corresponding conveyor frames 5, and the wire harness bodies 17 are clamped and fixed by means of two clamping plates 19 arranged on the side close to the two movable plates 18. Then, after the conveyor frame 5 rotates to a position corresponding to the stripping mechanism above the fixed plate 4, the two second sliders 23 are controlled to move in the corresponding second slide groove 21 toward the fixed plate 4, thereby driving the two movable plates 18 and the wire harness bodies 17 clamped and fixed by the two sets of clamping plates 19 toward the fixed plate 4. The two cutters 12 move in the same direction, so that one end of the wiring harness body 17 can pass through the gap between the two clamping blocks 11 and the two cutters 12. At this time, the telescopic end of the first electric telescopic rod 9 pushes one of the cutters 12 to move toward the other cutter 12, and the two cutters 12 cooperate to cut the position where the end of the wiring harness body 17 needs to be stripped. Then the second electric telescopic rod 10 is controlled to push one of the clamping blocks 11 to move toward the other clamping block 11, so that the two clamping blocks 11 cooperate to clamp and fix the wiring harness body 17. Then the moving seat 14 is controlled to drive the two cutters 12 to move in the direction away from the clamping block 11, and the insulating rubber layer at the end of the wiring harness body 17 is pulled off, so as to achieve the effect of automatically stripping the end of the wiring harness body 17.

[0047] If the other end of the wire harness body 17 also needs to be stripped, the servo motor preset inside the mounting seat 16 can be used to drive the conveyor frame 5 to rotate 180 degrees, and drive the other end of the wire harness body 17 to rotate to a position close to the stripping mechanism, and repeat the above steps, so that the two ends of the wire harness body 17 can be automatically stripped, thereby improving the stripping processing efficiency of multiple wire harness bodies 17.

[0048] Since a plurality of conveyor racks 5 are provided on the outer wall of the first conveyor belt 2, when the wire harness body 17 inside the front conveyor rack 5 is subjected to stripping processing, Figure 6 As shown, at this time, both ends of the wire harness body 17 inside the rear conveying rack 5 are clamped by two groups of corresponding arc-shaped rotating plates 20, so that the cleaning pad 37 set on the outer wall close to one side of the two groups of arc-shaped rotating plates 20 is in contact with the part to be stripped at the end of the wire harness body 17, and the two second sliders 23 move back and forth inside the second slide groove 21, thereby driving the wire harness body 17 clamped and fixed by the two groups of clamping plates 19 to move back and forth inside the conveying rack 5, so that during the friction between the two ends of the wire harness body 17 and the two groups of cleaning pads 37, the debris on the outer walls of both ends are automatically cleaned and removed, so as to avoid carrying the debris into the stripping mechanism and causing pollution to the wire harness body 17 after the subsequent stripping process.

[0049] After cleaning the debris on the end surface of the wire harness body 17, the two groups of fourth sliders 27 can be controlled to move back and forth inside the corresponding fourth slide groove 26, and the hot air can be discharged outward through the multiple air outlets 35 arranged on the outer wall of the two arc-shaped rotating plates 20 on the side close to each other, so that the end of the wire harness body 17 to be stripped can be heated and softened. Then, after controlling the two groups of fourth sliders 27 to move in the approaching direction, the two groups of arc-shaped rotating plates 20 are controlled to rotate in the approaching direction, so that the two groups of arc-shaped rotating plates 20 squeeze the cleaning pads 37 arranged inside them, so that the two groups of arc-shaped rotating plates 20 can have a clamping and fixing effect on the two ends of the wire harness body 17. As a result, under the premise of ensuring that the two groups of clamps 19 stably clamp the middle part of the wire harness body 17, the two groups of fourth sliders 27 are controlled to move in opposite directions, thereby driving the two groups of arc-shaped rotating plates 20 and the cleaning pads 37 arranged inside to perform auxiliary pulling and straightening treatment on the two ends of the softened wire harness body 17, so that the subsequent wire harness body 17 can be accurately inserted into the stripping mechanism with the help of the movement of the two second sliders 23, and it can also facilitate the two cutters 12 to quickly cut the insulating layer rubber surface of the wire harness body 17, so that the wire harness body 17 can be quickly stripped, thereby improving the stripping efficiency of the wire harness body 17.

[0050] After the wire harness body 17 is stripped of the insulating rubber layer at its end by means of the stripping mechanism, the two second sliders 23 are controlled to drive the two movable plates 18 to move and reset, so that the wire harness body 17 returns to the inside of the conveyor frame 5. At this time, the two groups of arc-shaped rotating plates 20 can be controlled to rotate and open in the direction away from each other, and then the two groups of fourth sliders 27 can be controlled again to drive the two groups of arc-shaped rotating plates 20 and other components to move in the direction of approaching, so that the two groups of arc-shaped rotating plates 20 at this time are moved toward the middle part of the wire harness body 17 until the two groups of arc-shaped rotating plates 20 move to the exposed part of the wire core close to the wire harness body 17. After being in position, the two groups of arc-shaped rotating plates 20 are controlled to rotate in the direction of approaching each other and drive the two cleaning pads 37 to closely abut against the exposed part of the wire core of the wiring harness body 17. As the two groups of fourth sliders 27 are controlled to move in the direction of moving away from each other, the two groups of arc-shaped rotating plates 20 are driven to move on the surface of the exposed part of the wire core of the wiring harness body 17, and the wire core at the end of the wiring harness body 17 is rubbed and cleaned to clean the remaining debris. The exposed part of the wire core at the end of the wiring harness body 17 can also be shaped to avoid deformation and bending of the copper wire at the exposed part of the wire core, which affects the subsequent processing.

[0051] At the same time, after the two groups of arc-shaped rotating plates 20 drive the cleaning pads 37 to rub and clean the exposed parts of the wire cores of the wiring harness body 17, if one end of the wiring harness body 17 is peeled, the two arc-shaped rotating plates 20 near the peeled wiring harness body 17 can be controlled to rotate in directions away from each other, driving the two cleaning pads 37 to slightly contact the exposed parts of the wire cores of the wiring harness body 17, and controlling the two unpeeled electric sliders 36 near the other end of the wiring harness body 17 to move inside the corresponding arc-shaped grooves 34, driving the wiring harness body 17 at this time to rotate slightly inside the conveyor frame 5, so that the exposed parts of the wire cores of the wiring harness body 17 are in contact with the two corresponding cleaning pads. The inner wall of the cleaning pad 37 is in rotating friction contact, which further improves the effect of cleaning the residual debris on the exposed part of the wire core of the wiring harness body 17; if the wiring harness body 17 is peeled at both ends, the above-mentioned method can also be used to first control one group of arc-shaped rotating plates 20 to clamp and fix one end of the wiring harness body 17, and drive the wiring harness body 17 to rotate by moving two of the electric sliders 36. After cleaning one end of the wiring harness body 17, control the other group of arc-shaped rotating plates 20 to clamp the cleaned wiring harness body 17, so that the wiring harness body 17 continues to rotate with the help of the movement of the other two electric sliders 36, and the other end of the wiring harness body 17 is cleaned.

[0052] After the exposed part of the wire core of the wiring harness body 17 is cleaned, as the first conveyor belt 2 continues to rotate, the conveyor frame 5 is driven to rotate downward to the bottom. At this time, the conveyor frame 5 corresponds to the position of the two rectangular blocks 6, and the two ends of the wiring harness body 17 are still located inside the two sets of arc-shaped rotating plates 20. The telescopic ends of the two corresponding third electric telescopic rods 25 are controlled to retract, and the clamping effect of the two sets of clamping plates 19 on the middle part of the wiring harness body 17 is released. As the two double-headed screws 29 are controlled to rotate, the two corresponding moving blocks 32 are driven to move in a direction close to each other, and the two lifting seats 31, the two arc-shaped rotating plates 20 and the clamped wiring harness body 17 are driven to move downward together, until the two sets of arc-shaped rotating plates 20 move downward to the position below the two industrial cameras 7. With the help of the two industrial cameras 7, the exposed part of the wire core after the stripping treatment at the end of the wiring harness body 17 can be visually identified and detected to detect whether the stripping treatment at the end of the wiring harness body 17 is qualified.

[0053] In order to ensure that the two industrial cameras 7 can more comprehensively identify and detect the exposed wire core parts of the wiring harness body 17, the two groups of electric sliders 36 can be controlled to move inside the corresponding arc grooves 34 at the same time, driving the wiring harness body 17 to rotate slightly inside the two groups of arc-shaped rotating plates 20, so that the two industrial cameras 7 can comprehensively identify and detect the exposed wire core parts of the wiring harness body 17, thereby further improving the accuracy of detecting the exposed wire core parts of the wiring harness body 17.

[0054] If the harness body 17 is in a qualified state after being detected by the two industrial cameras 7, the two corresponding fourth electric telescopic rods 30 can be controlled to extend their telescopic ends downward, thereby driving the two sets of arc-shaped rotating plates 20 and the harness body 17 to move downward to a position close to the second conveyor belt 3. As the two sets of arc-shaped rotating plates 20 are controlled to rotate in a direction away from each other, the clamped harness body 17 falls downward to the top of the second conveyor belt 3. By controlling the extension of the telescopic end of the fourth electric telescopic rod 30, the harness body 17 falls downward to the top of the second conveyor belt 3 in the subsequent process. The height becomes lower, so as to prevent the qualified wiring harness body 17 from falling directly downward from a higher position, which may easily cause damage to both ends of the wiring harness body 17; the qualified wiring harness body 17 can be conveyed to the right end with the help of the second conveyor belt 3, so as to facilitate the rapid unloading and collection of the qualified wiring harness body 17; the unqualified wiring harness body 17 is driven by the continued rotation of the first conveyor belt 2 to rotate upward again to the vicinity of the loading robot or the staff, and can be removed by the robot or manually, so as to facilitate the classification and discharge of the qualified wiring harness body 17 and the unqualified wiring harness body 17.
