Description

Technical Field

[0001] The present invention belongs to the technical field of cable manufacturing, and in particular relates to a wire core guiding unit, a wire core covering device, a cable manufacturing equipment and a cable manufacturing method. Background Art

[0002] Cables are used to transmit power and / or signals and are widely used in various fields. Cables usually include a core composed of a conductor or wire and an insulating coating coated on the outer surface of the core. The corresponding manufacturing equipment usually includes a guide wheel mechanism, an extruder, and a traction machine, wherein the extruder has a heating mechanism, a head with a coating core, and an extrusion mechanism.

[0003] During the manufacturing process, the traction machine continuously pulls the wire core, and the wire core enters the coating core of the extruder head under the guidance of the guide wheel mechanism. The heating mechanism of the extruder heats the coating material in a solid particle state to make it a molten fluid state, and then the molten coating material is extruded into the coating core through the extrusion mechanism of the extruder, so that the coating material is wrapped around the wire core in the head to form a cable.

[0004] When using the above equipment to manufacture cables, the operator needs to first select a coating core of corresponding size according to the specifications of the cable to be manufactured and load it into the machine head, then pass the wire core through the coating core, observe with the naked eye whether the center of the wire core is aligned with the center of the coating core, and manually adjust it to align. This operation is very inconvenient, and the alignment method of naked eye observation cannot guarantee the accuracy of alignment, which easily causes the core wire to be eccentric relative to the center of the coating core, causing the following problems: First, due to the eccentricity of the wire core, the distance from the outer surface of the wire core to the center hole wall of the coating core is uneven, which will cause the thickness of the coating material to be uneven, affecting the quality of the cable; second, because the wire core is at room temperature and the coating core is at a high temperature of more than 300°C, the eccentric wire core may abut against the side wall of the center hole of the coating core, causing the temperature of the coating core to drop, and the temperature and cooling time of the molten coating material are uneven, resulting in uneven internal stress of the cable package, which is manifested as fine cracks in the cable coating layer, etc., affecting the quality and service life of the cable.

[0005] Therefore, in order to solve the above problems, a device and method are needed that can conveniently align the center of the wire core with the center of the covering mold core. Summary of the invention

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the wire core guiding unit, wire core covering device cable manufacturing equipment and cable manufacturing method of the present invention are specifically described below in combination with embodiments and drawings.

[0042] <Example 1>

[0043] This embodiment provides a cable manufacturing device and a method for manufacturing a cable using the cable manufacturing device.

[0044] Figure 1 is a three-dimensional diagram of the cable manufacturing equipment in this embodiment.

[0045] like Figure 1 As shown, the cable manufacturing equipment 1000 includes a wire core coating device 100, a cable cooling device 200 and a traction device (not shown in the figure). The wire core coating device 100 is used to coat the coating material on the outer surface of the wire core to form a cable, and the cable cooling device 200 is arranged downstream of the wire core coating device 100, and its input end is close to the output end of the wire core coating device 100. The cable cooling device 200 is used to cool the cable coated by the wire core coating device 100. The traction device is arranged downstream of the cable cooling device 200, and is used to pull the cable / wire core and pull the cable / wire core to move in the forward direction, so as to continuously manufacture the cable.

[0046] Figure 2 is a three-dimensional diagram of the wire core covering device in this embodiment, Figure 3 is a side view of the cable manufacturing equipment in this embodiment.

[0047] like Figure 2 and Figure 3 As shown, the wire core coating device 100 includes a device housing 110, a feeding unit 120, a wire core coating unit 130 and a wire core guiding unit 140. The feeding unit 120 is used to receive granular coating materials and heat the coating materials into a molten state. The wire core coating unit 130 is used to coat the molten coating material on the outer surface of the wire core, thereby forming a cable. The wire core guiding unit 140 is used to guide the wire core to be coated to the wire core coating unit 130. The feeding unit 120 and the wire core coating unit 130 can adopt the structure in the prior art.

[0048] Figure 4 yes Figure 2 Enlarged view of the part within the middle circle A.

[0049] like Figure 4 As shown, the core coating unit 130 includes a coating core 131, and the coating core 131 has a center hole 131a for the core to pass through at the axial center position. The coating core 131 has an annular groove inside, and the groove is connected to the pipeline of the feeding unit 120. The molten coating material reaches the annular groove through the pipeline and is coated on the core portion that penetrates the coating core 131. In order to make the coating material uniformly coat the core circumferentially, it is necessary to align the center of the core with the center of the center hole 131a at the center position of the coating core 131 as much as possible.

[0050] Figure 5 3D is a perspective view of the wire core guide unit in this embodiment.

[0051] like Figure 4 and Figure 5 As shown, the wire core guiding unit 140 of this embodiment includes a base 141, a guide wheel mechanism 142, a moving mechanism 143, a driving mechanism 144, and a control mechanism (not shown in the figure). The guide wheel mechanism 142 is used to guide the wire core, under which the wire core continuously enters the covering mold core 131. The moving mechanism 143 is used to move the guide wheel mechanism 142 so that the center of the wire core to be covered is aligned with the center hole 131a at the center position of the covering mold core 131. The driving mechanism 144 is used to drive the moving mechanism 143 to move. The control mechanism is used to control the driving mechanism 144 so that the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel mechanism 142 to a position where the center of the wire core can be aligned with the center hole 131a at the center position of the covering mold core 131.

[0052] The base 141 includes a base support 1411 and a base plate 1412. The base support 1411 is fixedly connected to the side of the device housing 110, and the base plate 1412 is fixedly connected to the end extending from the base support 1411, and the base plate 1412 is horizontally arranged.

[0053] The guide wheel mechanism 142 includes a guide wheel bracket 1425, a first guide wheel 1421, a second guide wheel 1422, and a third guide wheel 1423. The guide wheel bracket 1425 is a rectangular plate, and the first guide wheel 1421, the second guide wheel 1422, and the third guide wheel 1423 are mounted on the same surface of the guide wheel mounting plate 1421, and are arranged in series at equal intervals along the length direction of the guide wheel bracket 1425. In this embodiment, the first guide wheel 1421, the second guide wheel 142, and the third guide wheel 1423 have the same shape and size.

[0054] Figure 6 yes Figure 3 The enlarged view of the inner part of the middle circle B shows a winding method of the wire core.

[0055] like Figure 6 As shown, along the forward direction of the wire core 400, the winding core 400 is sequentially wound around the upper end of the third guide wheel 1423, the lower end of the second guide wheel 1422, and the upper end of the first guide wheel 1421, and extends horizontally from the upper end of the first guide wheel 1421 to the center hole 131a at the center position of the covering mold core 131.

[0056] Figure 7 It is a schematic diagram of winding the wire core around the guide wheel of the wire core guide unit in this embodiment, showing another winding method of the wire core.

[0057] like Figure 7 As shown, another winding method can also be adopted. Along the forward direction of the wire core 400, the winding core 400 is sequentially wound around the lower end of the third guide wheel 1423, the upper end of the second guide wheel 1422, and the upper end of the first guide wheel 1421, and horizontally extends from the upper end of the first guide wheel 1421 to the center hole 131a at the center position of the covering mold core 131.

[0058] Since the first guide wheel 1421 is the last guide wheel before entering the covering core mold 131 , the first guide wheel 1421 becomes a guiding structure for guiding the wire core to enter the covering core mold 131 .

[0059] Figure 8 It is a three-dimensional diagram of the first guide wheel in this embodiment.

[0060] like Figure 8As shown, the periphery of the first guide wheel 1421 has a guide groove 1421a, and the guide groove 1421a has an arc bottom surface with a radius of R1 and two oblique side surfaces that are tangent to the arc bottom surface and extend upward on both sides in a V-shaped manner, so that its cross-section is generally approximately V-shaped. In this embodiment, there are various specifications of the wire cores, some of which have a radius less than or equal to R1. When these wire cores are wound on the first guide wheel 1421, the outer surface of the wire core contacts the lowest point of the arc bottom surface of the guide groove 1421a; the diameter of other wire cores is greater than R1. When these wire cores are wound on the first guide wheel 1421, they are stuck between the two oblique side surfaces of the guide groove 1421a and do not contact the arc bottom surface, that is, there is a certain distance between the outer surface of these wire cores and the lowest point of the arc bottom surface.

[0061] The guide groove 1421a may also be a U-shaped guide groove, which has an arc bottom surface with a radius of R2 and two straight side surfaces that are tangent to the arc bottom surface and extend upward on both sides in a U-shaped manner, so that its cross section is approximately U-shaped as a whole. The radius R2 of the arc bottom surface of the U-shaped guide groove is greater than the radius of all the wire cores, that is, when wire cores of different specifications are wound on the guide wheel with the U-shaped guide groove, they all contact the lowest point of the arc bottom surface of the U-shaped guide groove.

[0062] In order to adjust the position of the first guide wheel 1421 relative to the covering core 131, thereby adjusting the position of the wire core relative to the covering core 131, a moving mechanism 143 capable of moving the guide wheel bracket 1425 is provided. The moving mechanism 143 includes a first moving assembly 1431, a second moving assembly 1432, a third moving assembly 1433, and a fourth moving assembly 1434. The first moving assembly 1431 is used to drive the guide wheel bracket 1425 to move along the forward direction of the wire core; the second moving assembly 1432 is used to drive the guide wheel bracket 1425 to move in the left-right direction; the third moving assembly 1433 is used to drive the guide wheel bracket 1425 to move in the up-down direction; and the fourth moving assembly 1434 is used to drive the guide wheel bracket 1425 and the first to third moving assemblies to move as a whole in the forward direction or in the reverse direction of the forward direction.

[0063] The fourth moving assembly 1434 includes two fourth linear guide rails, four fourth sliders and a support plate. The two fourth linear guide rails are installed on the support plate 1412 in parallel with each other, and their extension direction is horizontal and parallel to the forward direction of the wire core. The four sliders are slidably engaged on the two linear guide rails, and the support plate is fixed on the four sliders and can move along the extension direction of the linear guide rails.

[0064] The fourth moving component 1434 is used for the operator to manually move the guide wheel bracket 1425 so that the guide wheel bracket 1425 is relatively far away from the covering core 131, so that there is enough space between the guide wheel bracket 1425 and the covering core 131, so that the operator can insert the wire core to be covered into the center hole 131a of the covering core 131.

[0065] The second moving component 1432 includes a second linear guide and a second slider. The second linear guide is fixedly mounted on the supporting plate of the fourth moving component 1434. Its extension direction is horizontal and perpendicular to the extension direction of the fourth linear guide. The second slider can be slidably engaged on the second linear guide.

[0066] The third moving assembly 1433 includes a third linear guide and a third slider. The third linear guide is fixedly mounted on the second slider, and its extension direction is vertical and perpendicular to the extension directions of the second linear guide and the fourth linear guide. The third slider is slidably engaged with the third linear guide.

[0067] The first moving assembly 1431 includes a first linear guide and a first slider. The first linear guide is fixedly mounted on the third slider, and its extension direction is horizontal and perpendicular to the extension direction of the third linear guide. The first slider is slidably engaged with the first linear guide. The guide wheel bracket 1425 is fixedly mounted on the first slider, and the surface direction of the guide wheel bracket 1425 is parallel to the extension direction of the first linear guide, so that the three guide wheels are arranged vertically.

[0068] The driving mechanism 144 includes a first driving component 1441, a second driving component 1442, and a third driving component 1443, which are respectively used to drive the sliders of the first moving component 1431, the second moving component 1432, and the third moving component 1433 to move, and each includes a servo motor, a screw rod, and a connecting part. The slider of the moving component is installed on the connecting part, and the connecting part is installed on the screw rod. The servo motor drives the screw rod to rotate, driving the connecting part and the slider to move.

[0069] The control mechanism controls the driving mechanism 144 to drive the moving mechanism 143 to move the guide wheel bracket 1425 according to the specifications of the wire core, so that the first guide wheel 1421 moves from the initial position to an alignment position corresponding to the wire core to be carried and aligns the wire core with the center position of the covering mold core 131.

[0070] Fig. 9 It is a block diagram of the control mechanism in this embodiment.

[0071] like Fig. 9As shown, the control mechanism 145 includes: a data storage unit 1451, an input display unit 1452, a reset output unit 1453, a reset detection unit 1454, a retrieval judgment output unit 1455, a first displacement detection unit 1456, a second displacement detection unit 1457, a third displacement detection unit 1458, a deviation judgment output unit 1459 and a guide side control unit 1460.

[0072] The data storage unit 1451 is used to store different specifications of multiple wire cores and movement information corresponding to each specification from an initial position to an alignment position.

[0073] The input display unit 1452 is used to allow the operator to input the specifications of the wire core to be coated and use them as the current specifications. Specifically, the input display unit 1452 includes a display screen, which displays a corresponding input screen. The input screen includes a text box for filling in the wire core diameter and a confirmation button. After the operator uses a caliper to measure the diameter of the wire core to be coated, the measured diameter is filled in the text box and confirmed by the confirmation button. The wire core includes a single-strand wire core with only a single wire and a multi-strand wire core formed by twisting multiple wires. For a multi-strand wire core, the diameter measured at its thickest position is used as its diameter for input.

[0074] The reset output unit 1453 outputs the reset movement information to the driving mechanism 143. The driving mechanism 143 drives the moving mechanism 142 to move the guide wheel bracket 1425 according to the reset movement information, so that the first guide wheel 1421 is moved to the initial position. In this embodiment, the position of the first guide wheel 1421 when the lowest point of the arc bottom surface of the guide groove 1421a of the first guide wheel 1421 is aligned with the center position of the covering core 131 is used as the target position, and the initial position is located 100 mm directly below the target position. Once the operator confirms the input wire core specification through the input display unit 1452, the reset output unit 1453 outputs the reset movement information.

[0075] The reset detection unit 1454 is used to detect whether the guide wheel bracket 1425 is reset to the initial position. In this embodiment, the reset detection unit 1454 includes a photoelectric sensor arranged next to the initial position. Once the reset output unit 1453 outputs the reset movement information, the reset detection unit 1454 starts to detect and generates a corresponding signal when it detects that the guide wheel bracket 1425 is reset to the initial position.

[0076] The search and determination output unit 1455 searches the data storage unit 1451 based on the input current specification and the shape information of the guide groove, determines the corresponding movement information and outputs it as the current movement information to the driving mechanism 144. Once the reset detection unit 1454 detects that the guide wheel bracket 1425 is reset to the initial position, the driving mechanism 144 drives the moving mechanism 143 to drive the guide wheel bracket 1425 to move from the initial position to the corresponding alignment position according to the current movement information.

[0077] Among them, the retrieval determination output unit 1455 retrieves the corresponding basic movement information according to the input current specification, retrieves the corresponding guide groove movement information according to the input current specification and the shape information of the guide groove, and calculates the current movement information based on the basic movement information and the guide groove movement information. The current movement information includes the forward direction movement information, the up-down direction movement information and the left-right direction movement information for the first to third drive components respectively. The first drive component 1441 drives the first moving component 1431 to move according to the forward direction movement information, so that the guide wheel bracket 1425 moves a corresponding distance in the forward direction; the second drive component 1442 drives the second moving component 1432 to move according to the up-down direction movement information, so that the guide wheel bracket 1425 moves a corresponding distance in the up-down direction; the third drive component 1443 drives the third moving component 1433 to move according to the left-right direction movement information, so that the guide wheel bracket 1425 moves a corresponding distance in the left-right direction.

[0078] In this embodiment, since the initial position is located 100 mm below the target position, according to the radius a of the wire core and the distance b from the outer surface of the wire core to the lowest point of the V-shaped guide groove 1421a, the first guide wheel 1421 moves upward a distance of (100-ab) mm from the initial position to the alignment position, so that the center of the wire core is aligned with the center position of the covering mold core 131. Therefore, the data storage unit 1451 stores the diameters of wire cores of various specifications and the corresponding distances moved upward from the initial position, and the retrieval and determination output unit 1455 can obtain the corresponding moving distance as basic moving information based on the input diameter; the data storage unit 1451 also stores the distance between the outer surface of the wire core and the lowest point of the V-shaped guide groove when the wire cores of various specifications are embedded in the V-shaped guide grooves of various specifications, and the retrieval and determination output unit 1455 retrieves or calculates the corresponding moving distance as the guide groove moving information based on the input wire core diameter, the diameter of the arc bottom surface of the V-shaped guide groove, and the angle between the two inclined side surfaces of the V-shaped guide groove, and finally obtains the total moving distance according to the above formula, and then decomposes the moving distance into the moving distances along the above three directions, and outputs them to the corresponding servo motor.

[0079] The first displacement detection unit 1456 is used to detect the moving distance of the first moving component 1431 driven by the first driving component 1441 in the forward direction relative to the initial position as the first actual displacement information. In this embodiment, the first displacement detection unit 1456 obtains the pulse feedback of the servo motor of the first driving component 1441, and the number of rotations of the servo motor can be deduced according to the obtained pulse, and then the moving distance along the forward direction can be calculated according to the number of rotations.

[0080] The second displacement detection unit 1457 is used to detect the moving distance of the second moving assembly 1432 driven by the second driving assembly 1442 in the up-down direction relative to the initial position as the second actual displacement information. The details are the same as the first displacement detection unit 1455 and will not be described again.

[0081] The third displacement detection unit 1458 is used to detect the moving distance of the third moving assembly 1433 driven by the third driving assembly 1443 in the left-right direction relative to the initial position as the third actual displacement information. The details are the same as the first displacement detection unit 1455 and will not be repeated here.

[0082] The deviation determination output unit 1459 determines whether there is any displacement deviation between the first actual displacement information and the forward direction movement information, between the second actual displacement information and the up-down direction movement information, and between the third actual displacement information and the left-right direction movement information. If it is determined that there is any displacement deviation, the corresponding displacement deviation is output to the driving mechanism 143, so that at least one of the first driving component 1441, the second driving component 1442, and the third driving component 1443 is driven accordingly according to the displacement deviation. In this way, the moving distance of the guide wheel bracket 1425 can be detected in real time during the process of the driving mechanism 144 driving the guide wheel bracket 1425 to move, so as to ensure that the guide wheel is actually moved to the alignment position where the center of the wire core is aligned with the center position of the covering mold core 131.

[0083] The guide-side control unit 1460 is used to control the operation of the above-mentioned functional units.

[0084] The cable cooling device 200 can adopt the structure in the prior art. In this embodiment, the cable cooling device 200 has a cooling tank 210, in which coolant is contained, and the two ends of the cooling tank 210 in the length direction respectively have a penetration notch 210a for the cable to pass through and a penetration notch (not shown in the figure) for the cable to pass through. The penetration notch 210a is located near the covering mold core 131, and the connecting direction of the penetration notch 210a and the penetration notch is parallel to the extension direction of the center hole 131a of the covering mold core 131, so that the cable can pass through the cooling tank 210 without changing the direction after passing through the center hole 131a.

[0085] The traction device is arranged downstream of the cable cooling device 200, and is used to pull the cable / core to move it along the forward direction, and the structure in the prior art may be adopted.

[0086] In this embodiment, when the cable manufacturing device 1000 is used for cable manufacturing, the operator first needs to move the guide wheel bracket 1425 to a position away from the covering mold core 131 through the fourth moving component 1434, wind the wire core around the guide wheel mechanism 14, and sequentially pass the wire core through the center hole 131a of the covering mold core 131, the insertion gap of the cooling groove, and the exit gap of the cooling groove, and then connect the wire core to the traction device. Then, the operator measures the diameter of the wire core with a tool such as a caliper, and checks the shape and size of its guide groove 1421a according to the model of the first guide wheel 1421 for subsequent input.

[0087] Fig.10 4 is a flow chart of the cable manufacturing method in this embodiment.

[0088] like Fig.10 As shown, based on the above-mentioned cable manufacturing equipment 1000, in this embodiment, the cable manufacturing method specifically includes the following steps:

[0089] In step S1-1, the measured diameter of the wire core and the shape information of the guide groove 1421a of the first guide wheel 1421 are input through the input display unit 1452, and the operator proceeds to step S1-2 after confirmation.

[0090] In step S1 - 2 , the reset output unit 1453 outputs reset movement information to the driving mechanism 144 .

[0091] In step S1-3, the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 to the initial position according to the reset movement information.

[0092] Step S1 - 4 , the retrieval determination output unit 1454 retrieves the data storage unit 1451 and determines the corresponding movement information according to the input wire core diameter and the shape information of the guide groove 1421 a , and outputs the movement information to the driving mechanism 144 .

[0093] Step S1-5, the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 to the alignment position according to the movement information.

[0094] During the movement of the guide wheel bracket 1425, the first displacement detection unit 1455, the second displacement detection unit 1456 and the third displacement detection unit 1457 continuously detect the displacement of the guide wheel bracket 1425 in the corresponding directions, the deviation determination output unit 1458 continuously outputs the displacement deviation according to the detection results of the three displacement detection units, and the driving mechanism 144 performs corresponding drive according to the displacement deviation.

[0095] Step S1-6, the traction device pulls the wire core to move it in the forward direction. During the movement, the covering mold core 131 of the wire core covering unit 130 covers the wire core part therein to form a cable, and the cable cooling device 200 cools the cable part therein.

[0096] Through the above steps, before coating the wire core, the center position of the wire core and the coating mold core can be aligned according to the diameter of the wire core and the shape and size of the guide groove on the guide wheel.

[0097] Functions and Effects of Embodiment 1

[0098] According to the wire core guiding unit, wire core covering device, cable manufacturing equipment and cable manufacturing method provided in this embodiment, since the wire core guiding unit has a control mechanism, the control mechanism controls the driving mechanism to drive the moving mechanism to move the guide wheel mechanism according to the specifications of the wire core, so that the first guide wheel is moved to an alignment position corresponding to the wire core to be carried and so that the center of the wire core is aligned with the center position of the covering mold core, thereby automatically aligning the center of the wire core with the center of the covering mold core, and the operator no longer needs to observe with the naked eye and manually adjust the alignment, which can save a lot of manpower and time, and improve the quality and production efficiency of the cable. In addition, in this embodiment, automatic alignment is performed based on the diameter of the wire core to determine the corresponding moving distance, which can achieve more precise alignment. When using wire cores of different specifications or replacing the covering mold core, automatic alignment can be conveniently performed again.

[0099] In the embodiment, the control mechanism includes a data storage unit, an input display unit and a retrieval and determination output unit. The data storage unit stores a variety of wire core specifications and the movement information corresponding to each specification. Therefore, the operator only needs to input and confirm the measured wire core diameter through the input display unit. The retrieval and determination output unit retrieves the data storage unit according to the input diameter and automatically determines the corresponding movement information and outputs it to the driving mechanism. The driving mechanism accurately moves the first guide wheel to the alignment position based on the movement information.

[0100] In the embodiment, the first guide wheel has a guide groove for guiding the wire core, which is a V-shaped groove or a U-shaped groove. The control mechanism determines the corresponding movement information according to the input wire core diameter and the shape and size of the guide groove. In this way, no matter whether the wire core fits in the guide groove or is stuck in the V-shaped groove due to its relatively large diameter, the center of the wire core can be aligned with the center of the covering mold core through the corresponding movement information.

[0101] In the embodiment, the moving mechanism is a three-directional moving mechanism, and the control mechanism decomposes the determined movement information into movement information in three directions, and outputs it to each servo motor respectively. In addition, the control mechanism also includes three displacement detection units in three directions and a deviation determination output unit, which can detect in real time whether there is a deviation between the moving distance in the three directions and the target distance, and control the corresponding servo motor accordingly, so as to further ensure that the first guide rail moves to the alignment position.

[0102] <Example 2>

[0103] The present embodiment provides a cable manufacturing device and a method for manufacturing a cable using the cable manufacturing device. In the present embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.

[0104] Compared with the first embodiment, the difference lies in that the structure and function of the wire core guiding unit of the cable manufacturing equipment of this embodiment are different.

[0105] Fig.11 It is a block diagram of the control mechanism in this embodiment.

[0106] like Fig.11 As shown, compared with the first embodiment, the control mechanism 145 of this embodiment further includes a specification detection unit 1461, an image acquisition unit 1462, an image analysis and determination unit 1463, and a fine adjustment output unit 1464.

[0107] The specification detection unit 1461 includes a caliper arranged upstream of the guide wheel mechanism 142 (upstream based on the forward direction of the wire core). The wire core to be coated wound on the guide wheel passes through the measuring hole in the middle of the caliper, and the caliper can measure the diameter of the wire core.

[0108] The search and determination output unit 1455 searches the data storage unit 1451 according to the diameter measured by the specification detection unit 1461, determines the corresponding movement information, and outputs the movement information to the driving mechanism 144. In this embodiment, the settings of the initial position and the target position are the same as those in the first embodiment. The target position is 100 mm above the initial position. According to the measured radius a of the wire core, the movement information is (100-a) mm upward.

[0109] The image acquisition unit 1462 includes a camera disposed at an upstream position of the first guide wheel 1421, and is used to, when the first guide wheel 1421 is moved to the alignment position, take the forward direction of the wire core as the shooting direction from the upstream position of the first guide wheel 1421, take the picture including at least the guide groove 1421a of the first guide wheel 1421 and the covering mold core 131 as the shooting object, and take the image obtained by the shooting as the current image to be analyzed. In this embodiment, the camera is mounted on the guide wheel bracket 1425 and is located near the upper end of the first guide wheel 1421. The shooting direction of the camera is roughly consistent with the length direction of the guide wheel bracket 1425, so that the guide groove 1421a of the first guide wheel 1421 can be clearly photographed, and the covering mold core 131 in front of the first guide wheel 1421 can be photographed.

[0110] The image analysis and determination unit 1463 is used to analyze the current image to be analyzed acquired by the image acquisition unit 1461, analyze the shape of the guide groove 1421a (i.e., a V-shaped groove or a U-shaped groove), the position of the lowest point of the arc bottom surface of the guide groove 1421a, and the center position of the coating core 131, and determine whether to fine-tune the current position of the first guide wheel 1421 at least based on the specifications of the wire core to be coated and the analyzed shape of the guide groove 1421a, the lowest point of the guide groove 1421a and the relative position relationship between the center position of the coating core 131.

[0111] Specifically, before photographing the guide groove and the covering mold core, the camera is first calibrated to obtain the calibration relationship between the pixel size of the image taken and the actual physical size. The distance calculations mentioned below all involve the conversion between the pixel size and the actual physical size. Since the calibration and conversion are existing technologies, they will not be described in detail.

[0112] After the image is acquired, the shape of the guide groove 1421a is first analyzed based on the image. When it is analyzed that the guide groove 1421a is a U-shaped groove, the outer surface of the wire core is in contact with the lowest point of the U-shaped groove, that is, the distance between the outer surface of the wire core and the lowest point of the U-shaped groove is 0. When it is analyzed that the guide groove 1421a is a V-shaped groove, the distance between the outer surface of the wire core and the lowest point of the V-shaped groove is calculated based on the measured diameter of the wire core and the size of the V-shaped groove (including the radius of the arc bottom surface of the V-shaped groove and the angle between the two oblique sides of the V-shaped groove).

[0113] Furthermore, based on the image, the relative position relationship between the lowest point of the guide groove 1421a and the center position of the covering mold core 131 is analyzed. Specifically, the center position of the covering mold core 131 can be fitted according to the outer contour shape of the covering mold core 131 in the image, and the position of its lowest point can be identified according to the structural characteristics of the U-shaped groove or V-shaped groove, and then the distance between the center position of the covering mold core 131 and the lowest point of the guide groove is calculated.

[0114] The fine-tuning output unit 1464 calculates the fine-tuning distance according to the distance between the outer surface of the wire core and the lowest point of the guide groove 1421a and the distance between the center position of the covering mold core 131 and the lowest point of the guide groove 1421a analyzed and determined by the image analysis and determination unit 1463, and decomposes the fine-tuning distance into fine-tuning values ​​along the forward direction, the left-right direction, and the up-down direction, and outputs the fine-tuning values ​​in the three directions to the driving mechanism 144. The driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 according to the fine-tuning values ​​in the three directions, so that the center of the wire core wound on the first guide wheel 1424 is aligned with the center position of the covering mold core 131.

[0115] In this embodiment, other structures are the same as those in the first embodiment and will not be described again.

[0116] In this embodiment, when the cable manufacturing device 1000 is used for cable manufacturing, the operator first needs to move the guide wheel bracket 1425 to a position away from the covering mold core 131 through the fourth moving component 1434, wind the wire core around the guide wheel mechanism 14, and sequentially pass the wire core through the center hole 131a of the covering mold core 131, the cooling groove penetration gap, and the cooling groove penetration gap, and then connect the wire core to the traction device. After the operator confirms that the wire core is in place, the cable manufacturing device 1000 starts automatic alignment and cable manufacturing.

[0117] Fig.12 4 is a flow chart of the cable manufacturing method in this embodiment.

[0118] like Fig.12 As shown, the cable manufacturing method of this embodiment includes the following steps:

[0119] In step S2 - 1 , the reset output unit 1453 outputs reset movement information to the driving mechanism 144 .

[0120] In step S2-2, the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 to the initial position according to the reset movement information.

[0121] In step S2-3, the specification detection unit 1460 detects the diameter of the wire core.

[0122] Step S2 - 4 , the retrieval determination output unit 1454 retrieves the data storage unit 1451 according to the measured diameter of the wire core and determines the corresponding movement information, and outputs the movement information to the driving mechanism 144 .

[0123] Step S2-5, the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 to the target position according to the moving information.

[0124] During the movement of the guide wheel bracket 1425, the first displacement detection unit 1455, the second displacement detection unit 1456 and the third displacement detection unit 1457 continuously detect the displacement of the guide wheel bracket 1425 in the corresponding directions, the deviation determination output unit 1458 continuously outputs the displacement deviation according to the detection results of the three displacement detection units, and the driving mechanism 144 performs corresponding drive according to the displacement deviation.

[0125] Step S2-6, the image acquisition unit 1461 takes the forward direction of the wire core as the shooting direction from the upstream position of the first guide wheel 1421, and shoots the picture including the guide groove 1421a of the first guide wheel 1421 and the covering mold core 131 as the shooting object, and acquires the image as the current image to be analyzed.

[0126] In step S2-7, the image analysis and determination unit 1462 analyzes the current image to be analyzed, and determines whether to make fine adjustments to the current position of the first guide wheel 1421 based on the diameter of the wire core, the analyzed shape of the guide groove 1421a, and the relative position relationship between the lowest point of the guide groove 1421a and the center position of the covering mold core 131.

[0127] Step S2-8, when the judgment in step S2-7 is yes, the fine-tuning output unit 1463 calculates the fine-tuning values ​​in the forward direction, left-right direction, and up-down direction according to the diameter of the wire core, the shape of the guide groove 1421a and the above-mentioned relative position relationship, and inputs the fine-tuning values ​​to the driving mechanism 144.

[0128] Step S2-9, the driving mechanism 144 drives the moving mechanism 143 to move the guide wheel bracket 1425 according to the fine-tuning value, so that the center of the wire core carried by the first guide wheel 1421 is aligned with the center position of the covering mold core 131.

[0129] Among them, similar to step S2-7, in step S2-9, during the movement of the guide wheel bracket 1425, the first displacement detection unit 1455, the second displacement detection unit 1456 and the third displacement detection unit 1457 continuously detect the displacement of the guide wheel bracket 1425 in the corresponding directions, the deviation judgment output unit 1458 continuously outputs the displacement deviation according to the detection results of the three displacement detection units, and the driving mechanism 144 performs corresponding drive according to the displacement deviation.

[0130] Step S2-10, the traction device pulls the wire core to move it in the forward direction. During the movement, the covering mold core 131 of the wire core covering unit 130 covers the wire core part therein to form a cable, and the cable cooling device 200 cools the cable part therein.

[0131] Functions and Effects of Embodiment 2

[0132] According to the wire core guiding unit, wire core covering device cable manufacturing equipment and cable manufacturing method provided in this embodiment, on the basis of the functions and effects of the first embodiment, since the diameter of the wire core to be covered is automatically detected by the specification detection part (diameter gauge), there is no need to manually measure the diameter of the wire core by tools such as calipers and input confirmation, thereby further saving manpower and time, and the diameter of the wire core can be measured more accurately by the diameter gauge, thereby making the automatic alignment more precise.

[0133] In the embodiment, the control mechanism also includes an image acquisition unit, an image analysis and determination unit and a fine-tuning output unit. The image analysis and determination unit can automatically analyze the shape and size of the guide groove of the first guide wheel and the relative position relationship between the lowest point of the guide groove and the center of the covering mold core based on the acquired image. The fine-tuning output unit calculates the fine-tuning values ​​in three directions based on the automatically analyzed information and outputs them to the driving mechanism, thereby achieving more precise alignment. At the same time, the operator is no longer required to input information such as the shape and size of the guide groove, which further saves manpower and time, and can effectively avoid product quality problems caused by manual input errors.

[0134] In addition, during the fine-tuning process, the three displacement detection units in three directions also perform corresponding detections, and the deviation determination output unit also outputs the displacement deviations in the corresponding directions, thereby further ensuring the accuracy of the fine-tuning.

[0135] <Modification 1>

[0136] This variation provides a cable manufacturing device and a method for manufacturing a cable using the cable manufacturing device. Compared with the first embodiment, the difference is that in the cable manufacturing device 1000 of this variation, the structure of the guide wheel mechanism 142 is different.

[0137] Fig.13 This is a schematic diagram of the wire core being wound around the guide wheel of the wire core guide unit in this modification. Figure 1 , showing a guide wheel arrangement and corresponding wire core winding method.

[0138] like Fig.13 As shown, compared with the first embodiment, in this variation, the guide wheel mechanism 142 also includes an upper bracket 1426, an upper bracket driving assembly (not shown in the figure), and a lower bracket 1427.

[0139] The lower bracket 1427 is fixedly mounted on the guide wheel bracket 1425, and the upper bracket 1426 is movably mounted on the guide wheel bracket 1425 in the up and down directions and is located above the lower bracket 1427. The upper bracket driving assembly is used to drive the upper bracket 1426 to move in the up and down directions, thereby approaching or moving away from the lower bracket 1427.

[0140] The first guide wheel 1421 and the third guide wheel 1423 are mounted on the lower bracket 1427 and arranged in the horizontal direction. The second guide wheel 1422 is mounted on the upper bracket 1426 and is located between the first guide wheel 1421 and the third guide wheel 1423 in the vertical direction, that is, staggered with the first guide wheel 1421 and the third guide wheel 1423 in the vertical direction.

[0141] Along the advancing direction of the wire core, the wire core 400 is sequentially wound around the upper end of the third guide wheel 1423, the lower end of the second guide wheel 1422, and the upper end of the first guide wheel 1421, and horizontally extends from the upper end of the first guide wheel 1421 to the center hole 131a at the center of the covering mold core 131. Among them, the lower end of the second guide wheel 1422 is slightly lower than the upper ends of the first guide wheel 1421 and the third guide wheel 1423, so that the wire core portion wound thereon is pressed downward, so that the wire core is tensioned on the three guide wheels.

[0142] In the cable manufacturing method, in step S1-1, after the operator winds the wire core around the guide wheel mechanism 14, the operator also controls the upper bracket driving assembly through the input display unit 1452 to drive the upper bracket 1426 to move slightly downward, thereby pressing the second guide wheel 1422 on the upper bracket 1426 downward to tighten the wire core wound around the guide wheel mechanism 14.

[0143] In this variation, other structures and cable manufacturing methods are the same as those in the first embodiment and will not be described again.

[0144] In addition, the guide wheel mechanism 142 provided in this variation can also be applied to the second embodiment.

[0146] This modification provides a cable manufacturing device and a method for manufacturing a cable using the cable manufacturing device. Compared with the first modification, the difference is that in the cable manufacturing device 1000 of this modification, the structure of the guide wheel mechanism 142 is different.

[0147] Fig.14 This is a schematic diagram of the wire core being wound around the guide wheel of the wire core guide unit in this modification. Figure 2 , shows another guide wheel arrangement and corresponding core winding method.

[0148] like Fig.14 As shown, compared with the first modification, the guide wheel mechanism 142 of this modification further includes a fourth guide wheel 1424, the shape and size of which are the same as those of the other three guide wheels.

[0149] The fourth guide wheel 1424 is mounted on the upper bracket 1426, and the second guide wheel 1422 and the fourth guide wheel 1424 are arranged in the horizontal direction. The fourth guide wheel 1424 is located upstream of the third guide wheel 1423 in the vertical direction, that is, the second guide wheel 1422 and the fourth guide wheel 1424 are staggered with the first guide wheel 1421 and the third guide wheel 1423 in the vertical direction.

[0150] Along the forward direction of the wire core, the wire core 400 is sequentially wound around the lower end of the fourth guide wheel 1424, the upper end of the third guide wheel 1423, the lower end of the second guide wheel 1422, and the upper end of the first guide wheel 1421, and horizontally extends from the upper end of the first guide wheel 1421 to the center hole 131a at the center of the covering mold core 131. Among them, the lower end of the second guide wheel 1422 and the lower end of the fourth guide wheel 1424 are slightly lower than the upper ends of the first guide wheel 1421 and the third guide wheel 1423, so that the wire core portion wound thereon is pressed downward, so that the wire core is tensioned on the three guide wheels.

[0151] In this variation, other structures and cable manufacturing methods are the same as those in variation 1 and will not be described again.

[0152] In addition, the guide wheel mechanism 142 provided in this variation can also be applied to the second embodiment.
