DETAILED DESCRIPTION

[0052] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0053] like Figures 1 to 5 As shown, the present invention provides a fully automatic cable production system, including a main controller, a wire drawing unit 2, a twisting unit 3, an insulation unit 4, a cabling unit 5, a steel armoring unit 6, a sheath injection unit 7, a detection unit 8 and a winding unit 9, all of which are connected to the main controller signal.

[0054] There are multiple wire drawing units 2, each of which includes a plurality of wire drawing modules 20. The wire drawing modules 20 include a wire releasing mechanism 21, a module mechanism 22, a connecting mechanism 23, and a wire cutting mechanism 24. The wire releasing mechanism 21 is used to release the metal wire, the module mechanism 22 is used to allow the metal wire to pass through and force the metal wire to be elongated and thinned, the wire cutting mechanism 24 is used to cut the metal wire, and the connecting mechanism 23 is used to transfer the head end of the metal wire to the twisting unit 3.

[0055] The twisting unit 3 is used to wind a plurality of metal wires that have been subjected to the wire drawing process to form a twisted wire;

[0056] The insulation unit 4 is used to coat the twisted wire with insulation material to form a wire core;

[0057] The cabling unit 5 is used to twist a plurality of wire cores to form a twisted wire;

[0058] The steel armoring unit 6 is used to add a metal layer to the outer layer of the twisted wire;

[0059] The sheath injection unit 7 is used to inject a sheath layer on the outer layer of the twisted wire after the metal layer is added to make a cable;

[0060] The detection unit 8 is used to perform performance detection on the cable;

[0061] The reeling unit 9 is used to reel the qualified cables;

[0062] The main controller is used to select a corresponding number of wire drawing modules 20 to work or stop working according to changes in the specifications of the cables to be produced.

[0063] Specifically, when it is necessary to change the specifications of the produced cables, the staff only needs to input the specification parameters of the changed cables into the main controller, such as the number of twisted wires, the number of metal wires, etc., and then the main controller adjusts the number of wire pulling units 2 involved in the twisted wire output and the number of wire pulling modules 20 involved in the output of metal wires in each wire pulling unit 2 according to the input parameters. The specifications of the produced cables can be adjusted without stopping the machine, thereby improving efficiency.

[0064] In this embodiment, the mold mechanism 22 includes a turntable 221, a turntable drive assembly 222 and a plurality of wire drawing molds 223. The turntable drive assembly 222 is used to drive the turntable 221 to rotate; the plurality of wire drawing molds 223 are distributed on the turntable 221 in a circular array with the rotation axis of the turntable 221 as the center. The wire drawing mold 223 has a wire drawing hole, and the wire drawing hole has an output end. The inner diameters of the output ends of different wire drawing holes are different.

[0065] That is, in the present invention, the turntable drive assembly 222 is mainly composed of a motor and a reducer, which is used to drive the turntable 221 to rotate; and when the specification requirements of the metal wire change, the present invention can first use the wire cutting mechanism 24 to cut the metal wire at the input end of the wire drawing hole of the wire drawing mold 223 of the current wire drawing, and then use the turntable drive assembly 222 to drive the turntable 221 to rotate, so that the wire drawing hole with the inner diameter that meets the requirements at the output end is moved to the wire drawing station (for example, the top position of the turntable 221 is the wire drawing station), and then the connecting mechanism 23 puts the metal wire into the wire drawing hole with the inner diameter that meets the requirements and guides the metal wire to pass through the wire drawing hole and move it to the twisting unit 3, thereby realizing the automatic switching of the wire drawing mold 223 and improving efficiency.

[0066] Specifically, the main controller of the present invention selects a corresponding number of wire drawing modules 20 to work or stop working according to the changes in the cable specifications to be produced, specifically including:

[0067] S1. Obtain the metal wire diameter L of each core of the cable after the specification changes n ;

[0068] S2. Obtain the inner diameter L of the wire drawing die 223 of each die mechanism 22 in the currently working wire drawing die set 20. n ';

[0069] S3.Comparison with L n With L n 'If there is the same value, then keep the mold inner diameter L n 'The corresponding wire pulling mechanism continues to work;

[0070] S4. Obtain the number of cores n of the cable after the specification changes;

[0071] S5. According to the number of wire cores n and the number of wire pulling mechanisms that continue to work, select the corresponding number of wire pulling modules 20 to execute step S6;

[0072] S6. The wire release mechanism 21 stops working, the wire cutting mechanism 24 cuts the metal wire short, and then the turntable drive assembly 222 drives the turntable 221 to rotate so that the inner diameter of the output end is L n The wire drawing die 223 is switched to the wire drawing station; then the connecting mechanism 23 drives the wire to pass through the wire drawing die 223 on the wire drawing station and enter the stranding unit 3.

[0073] That is, the present invention can adjust not only the number of metal wires and twisted wires but also the diameter of each metal wire according to the specification changes of the produced cables, so that the cable specifications produced by the present invention are more numerous and more flexible through automatic switching.

[0074] Specifically, the connecting mechanism 23 includes a moving component 231, a wire accommodating groove 232, a wire wheel 233, a wire driving component 234, a visual device 235 and a wire moving robot 236. The wire accommodating groove 232 is used to accommodate the metal wire, the moving component 231 is used to drive the wire accommodating groove 232 to move, the wire wheel 233 is rotatably arranged in the wire accommodating groove 232, the wire driving component 234 is used to drive the wire wheel 233 to rotate to drive the metal wire in the wire accommodating groove 232 to move, the visual device 235 is used to identify whether the metal wire is output from the output end of the wire drawing mold 223, and the wire moving robot 236 is used to pick up the metal wire output from the wire drawing mold 223 according to the identification result of the visual device 235 and transfer the metal wire to the twisting unit 3.

[0075] During actual use, the metal wire passes through the wire accommodating groove 232 and then enters the wire drawing mold 223; when connection is required, the moving component 231 drives the wire accommodating groove 232 to move so that the metal wire is inserted into the wire drawing mold 223, and then the wire driving component 234 drives the wire wheel 233 to rotate to drive the metal wire to pass through the wire drawing mold 223, so that the metal wire passes through the wire drawing mold 223 and is output, and then the wire moving robot 236 grabs the metal wire and inserts it into the twisting unit 3 to achieve the connection effect.

[0076] In actual application, in order to ensure that the metal wire can smoothly pass through the wire drawing die 223, the metal wire can be processed in one of the following two ways:

[0077] 1. Use the following methods for the metal wire in the tank: Figure 3 The heating mechanism 2 performs heat treatment on the metal to soften the metal wire and make it easy to deform so that it can pass through the wire drawing die 223 smoothly;

[0078] Second, a corresponding wire pressing mechanism (not shown in the figure) is arranged in the receiving groove. The wire pressing mechanism can be composed of a plurality of punches, that is, the head end of the metal wire is forced to become thinner and longer through the impact force so that the metal wire can pass through the wire drawing die 223 sufficiently.

[0079] By using one of the above methods, or a combination of the two methods (heating first and then impacting), the head end of the metal wire is made thinner, so that the wire-moving robot 236 can grab the metal wire from the output end of the wire-drawing hole and transfer it to the twisting unit 3. Subsequently, the output of the wire-releasing mechanism 21 and the traction of the twisting unit 3 can ensure that the metal wire is subjected to sufficient force to pass through the wire-drawing mold 223, and the connection of the metal wire can be successfully completed without human intervention.

[0080] In this embodiment, the stranding unit 3 has a marking mechanism 31 and a shearing mechanism 32, wherein the marking mechanism 31 is used to mark the position where the quantity and / or specification of the metal wires are changed;

[0081] The shearing mechanism 32 is used to cut the marked position so that the cable transition section before and after the specification change is cut off and the cables before and after the specification change are separated.

[0082] Through the cooperation of the marking mechanism 31 and the wire cutting mechanism 24, the present invention can automatically distinguish the cable transition section generated when switching specifications without stopping the machine, and the twisting unit 3 can cut off the cable transition section in time, and use the cutting position as the dividing point of the cable before and after the specification change. During the subsequent winding, it can also ensure that cables of different specifications are wound into different material rolls respectively.

[0083] Specifically, the number of the stranding units 3 is the same as the number of the wire drawing units 2, and the winding unit further includes a winding mechanism 33, a wire outlet mechanism 34, a traction mechanism 35 and a winding drive mechanism 36, the winding drive mechanism 36 is used to drive the winding mechanism 33 to rotate, the winding mechanism 33 is used to guide the metal wire to move to the wire outlet mechanism 34, the wire outlet mechanism 34 is used to wind a plurality of metal wires to form a winding wire, the traction mechanism 35 is used to pull the metal wire from the winding mechanism 33 to the wire outlet mechanism 34, the winding drive mechanism 36 is used to drive the winding mechanism 33 to rotate, and the winding drive mechanism 36 is connected to the main controller signal;

[0084] The marking mechanism 31 is arranged between the winding mechanism 33 and the mold mechanism 22, and the shearing mechanism 32 is arranged between the outlet mechanism 34 and the insulating unit 4. The marking mechanism 31 can spray paint through a nozzle to achieve marking, and the shearing mechanism 32 uses its camera to identify the paint position for shearing.

[0085] That is, the beginning and the end of the cable transition section need to be marked before winding, and the cable transition section needs to be cut before the insulating material is coated, so as to avoid wasting the insulating material, and the cut cable transition section is easy to handle because it is a pure metal wire. After the cutting is completed, the traction mechanism 35 ensures that both ends of the cable can enter the insulating unit 4 smoothly.

[0086] Specifically, the main controller is also used to adjust the winding speed according to the changed specifications of the wire, including:

[0087] Y1. Compare the rotation direction and speed of wire winding before and after the specification change;

[0088] Y2. Control the winding drive mechanism 36 to drive the winding mechanism 33 to gradually reduce the speed to 0 and keep the winding mechanism 33 not rotating until all the wire drawing modules 20 are adjusted;

[0089] Y3. Control the winding drive mechanism 36 to drive the winding mechanism 33 to rotate according to the changed rotation direction and rotation speed.

[0090] The winding drive mechanism 36 is mainly composed of a motor and a reducer. When the quantity and specification of the metal wire are adjusted in the present invention, the winding drive mechanism 36 temporarily does not work, that is, the winding mechanism 33 does not rotate to facilitate the subsequent connection action; the winding mechanism 33 has a corresponding traction module to pull the metal wire entering the winding mechanism 33 so that it can be transmitted.

[0091] Specifically, the winding unit further comprises a feeding mechanism, which is used to feed the filler required for winding to the winding mechanism 33. For some winding wires that require filler, the present invention performs feeding and replenishment through the feeding mechanism.

[0092] Specifically, the traction mechanism 35 mainly comprises two traction wheels cooperating to achieve traction of the stranded wire, and the gap between the two traction wheels is adjustable, so that the traction mechanism 35 can be adaptively adjusted according to the specific outer diameter of the stranded wire after the specification changes.

[0093] In this embodiment, the detection unit 8 includes a detection device 81, a visual module 82 and a glue filling mechanism 83. The working method of the detection unit 8 includes:

[0094] A. Use the testing device 81 to test the insulation performance and withstand voltage performance of the cable. If the insulation performance is qualified, execute step D; otherwise, execute step B;

[0095] B. Obtaining the damaged position of the cable sheath layer through the visual module 82;

[0096] C. The damaged position of the sheath layer is repaired by the repair mechanism 83;

[0097] D. Transfer the cable to the reeling unit 9 for reeling.

[0098] That is, the detection device 81 mainly detects the voltage resistance and insulation performance of the cable, both of which are achieved through the detection device 81. When one of the indicators does not meet the standard, the cable sheath layer on the surface of the cable is preferentially detected to see if it is damaged, and the cable sheath layer is repaired by filling the damaged position with glue.

[0099] Since the cable is tested section by section, if the performance is unqualified, this section of the cable needs to be cut off. Therefore, in order to prevent the unqualified cable due to the damage of the cable sheath from being cut, the present invention adopts steps AD for processing, which can effectively reduce the scrap rate of the cable and save costs.

[0100] Specifically, the detection unit 8 further includes a re-inspection module 84, a shearing module 85 and a connection module 86; between steps C and D, it also includes:

[0101] C1. Perform a withstand voltage test on the cable after the patching by retesting module 84. If qualified, proceed to step D, otherwise proceed to step C2;

[0102] C2. The cable segment with unqualified insulation performance is sheared by shearing module 85;

[0103] C3. Connect the cut cables through the connection module 86.

[0104] That is, the insulation performance or voltage resistance of the cable is still unqualified after the glue repair. In this case, this section of the cable can only be directly cut off to ensure the quality of the cable produced by the present invention; and the cut cable is connected through the connection module 86. The connection method can use a special connection piece and a connector loading device 861 for loading. The specific method and structure will not be repeated here.

[0105] Specifically, there are multiple detection units 8 , which are arranged side by side in sequence; and only the detection unit 8 located at the end has the cutting module 85 and the connecting module 86 .

[0106] A storage mechanism 87 is provided between the detection unit 8 at the head end and the sheath injection unit 7; the storage mechanism 87 is used to store the cables whose sheath layers have been injected by the sheath injection unit 7 when the detection unit 8 is performing detection, and to release the stored cables after the detection is completed.

[0107] That is, each detection unit 8 of the present invention detects one end of the cable respectively, and after the detection is completed, the total length of multiple sections of the cable is moved at one time so that all the detected cables can be reeled up; since the production of cables is continuous, it is necessary to set up a storage mechanism 87 to pre-store the cables being produced at all times to compensate for the time required for detection, glue filling, cutting, and connection of the cables, so that the overall work rhythm is not delayed.

[0108] The main controller of the present invention can be a computer, and the insulation unit 4, the cabling unit 5, the steel armoring unit 6, the sheath injection unit 7 and the winding unit 9 are all conventional structures and will not be described here.

[0109] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
