Description

Technical Field

[0001] This invention belongs to the field of wire testing equipment, and more specifically, relates to a device and method for bidirectional winding of wires. Background Technology

[0002] In the production process of some wires, such as optical cables and electrical cables, some relevant performance tests need to be carried out before leaving the factory, such as bending tests in an environmental chamber.

[0003] During the construction and use of optical fiber cables, the bending performance of the fiber unit is a crucial factor affecting the quality of optical fiber communication. For example, when optical fibers need to be spliced ​​in a junction box, a certain number of reserved fiber units need to be coiled in the junction box. In addition, with the miniaturization of devices in data centers, high-density patch cords are coiled in patch panels, etc. Throughout the service life of the optical fiber, the operating temperature of the fiber unit will vary with changes in the environmental climate, such as in high-temperature and low-temperature regions, tropical regions, and the space environment used in aerospace. Currently, secondary coating materials for optical fibers include test items to verify the bending performance of optical fibers and optical fiber sleeves at high and low temperatures. The bending performance of optical fibers and sleeve units on a core axis of a certain size is verified. After the test, the optical fibers and sleeve units should be free of cracks or other physical losses.

[0004] Currently, fiber optic cable manufacturers primarily employ a manual, multi-person collaborative approach for these types of tests. The sample is wound onto a spool according to the number of turns and winding method specified in the test standard, and then the sample and spool assembly are placed in a standard or customer-required test chamber for testing. This manual winding method cannot avoid the bending stress generated by manual operation on the sample, nor can it guarantee the uniformity of stress during winding, or the repeatability and consistency of test results. Therefore, it severely affects the accuracy of the test results in subsequent harsh environmental tests, ensuring the sample truly reflects the product's performance. Summary of the Invention

[0005] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides a two-way winding device and method for wires, which can automatically wind wires onto a rotating shaft, reduce manual intervention, have a high degree of automation, have little impact on the normal high temperature and low temperature bending performance test of wires, and can ensure the uniformity of force during sample winding and the repeatability and consistency of test results.

[0006] To achieve the above objectives, according to one aspect of the present invention, a bidirectional wire winding apparatus is provided, comprising a frame, a motor, a chuck, a rotating shaft, a guide wheel, a clamp, and a moving platform, wherein: The motor is mounted on the frame, and the chuck is mounted on the motor to drive the chuck to rotate forward and backward. The rotating shaft is mounted on the chuck for winding the wire; The reversing guide wheel is mounted on the rotating shaft for reversing the direction of the wire wound on the rotating shaft, and the reversing guide wheel is connected to the rotating shaft. The clamp has a cable routing hole so that the cable passes through the cable routing hole and is locked in the cable routing hole, and the cable can move relative to the cable routing hole. The mobile platform is mounted on the frame, and the clamp is mounted on the mobile platform to drive the clamp to move in a direction parallel to the axis of the rotating shaft.

[0007] Preferably, the clamp includes a bracket and a wire clamping component detachably mounted on the bracket, the bracket being mounted on the movable platform, and the wire routing hole being disposed on the wire clamping component.

[0008] Preferably, the wire clamping component has a rubber ring on the wall of the wire routing hole to hold the wire in place.

[0009] Preferably, the wire clamp is hinged to the bracket via a hinge shaft, the axis of which is parallel to the axis of the rotating shaft.

[0010] Preferably, the side wall of the rotating shaft is provided with through holes to lock the wire clamping component after it extends into the through holes, and multiple through holes are provided.

[0011] Preferably, a pair of spring pins are installed on the inner wall of the rotating shaft at the position corresponding to each through hole to engage and clamp the wire clamping component.

[0012] Preferably, the moving platform is a three-axis moving platform so as to drive the wire to be wound around the guide wheel.

[0013] Preferably, the first end of the shaft is open; The side wall of the rotating shaft is provided with a sliding groove, and the sliding groove passes through the side wall of the rotating shaft and extends to the end face of the first end of the rotating shaft. The reversing guide wheel is open at the end away from the rotating shaft. A mounting platform is provided on the inner wall of the end of the reversing guide wheel near the rotating shaft. A connector is installed on the mounting platform. The connector passes through the slide groove and fixes the reversing guide wheel and the rotating shaft together.

[0014] Preferably, a limiting boss is provided on the outer wall of the reversing guide wheel to limit the position of the wire wound on the reversing guide wheel.

[0015] According to another aspect of the present invention, a method for bidirectional winding of wire is also provided, wherein the bidirectional winding is performed using the aforementioned equipment, comprising the following steps: 1) Installing the wire: The guide wheel divides the shaft into two sections. The first section is used to wind the wire in the first direction of rotation, and the second section is used to wind the wire in the second direction of rotation, which is opposite to the first direction of rotation. First, fix the first end of the wire on the first section of the shaft, and then pass the second end of the wire through the wire hole on the clamp, so that the wire is stuck in the wire hole. Pull the wire straight from the first end of the wire to the wire hole. 2) Winding wire on the first section: The motor drives the shaft to rotate forward, and the moving platform drives the clamp to move in a direction parallel to the axis of the shaft, so that the wire is wound a set number of turns on the first section of the shaft, and the last turn of the wire wound on the first section contacts the guide wheel. 3) Clamp movement: The rotating shaft stops rotating, and the moving platform continues to drive the clamp to move along the axis of the rotating shaft for a set stroke, so that the wire fits into a section of the outer arc of the guide wheel, so that when the rotating shaft reverses, the guide wheel can pull the wire so that the wire continues to wrap around the guide wheel and then wraps around the second section. 4) Winding the wire on the second section: The shaft reverses and the moving platform continues to move in a direction parallel to the axis of the shaft, so that the wire is wound on the second section a set number of times, and the first turn of the wire wound on the second section contacts the guide wheel. 5) Securing the wire: After removing the wire directly from the clamp, fix it to the set position on the second section of the rotating shaft, or remove the detachable wire clamp from the clamp and fix it together with the wire clamped on the wire clamp to the set position on the second section of the rotating shaft. Cut off the excess wire. The wire wound on the second section and the wire wound on the first section are symmetrically arranged on both sides of the guide wheel.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1) This invention can control the forward and reverse rotation direction of the rotating shaft, the displacement distance of the clamp, and the reversing of the guide wheel. The sample will automatically change direction from winding in the first direction to winding in the second direction opposite to the first direction on the rotating shaft. The degree of automation is high, which can reduce the impact of human intervention. It can solve the problem of test result failure caused by uneven force on the sample product and bending stress during the process of winding the sample on the rotating shaft, thus affecting the reliability acceptance of the sample. It can ensure the uniformity of force on the sample during winding and the repeatability and consistency of test results.

[0017] 2) The present invention uses a detachable rotating shaft on the chuck, which facilitates the clamping and disassembly of the rotating shaft and makes subsequent environmental testing easier.

[0018] 3) The guide wheel of this invention can reverse the direction of the wire relatively smoothly, and there will be basically no stress concentration at the reversal point of the wire, so as not to affect the normal high temperature and low temperature bending performance of the wire.

[0019] 4) The groove of the present invention can adapt to the position of the connector, so that the guide wheel can change its relative position with the rotating shaft and then be fixed by the connector, thereby adapting to the winding of wires of various diameters, such as different winding pitches.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figure 1 , Figure 2 The bidirectional winding equipment for wire includes a frame 1, a motor 2, a chuck 3, a rotating shaft 4, a guide wheel 5, a clamp 6, and a moving platform, wherein: The motor 2 is mounted on the frame 1, and the chuck 3 is mounted on the motor 2 to drive the chuck 3 to rotate forward and backward. Therefore, the motor 2 is a forward and reverse motor 2, which can drive the chuck 3 to rotate forward in the first direction and reverse in the second direction opposite to the first direction, so that the wire 7 can be wound in both directions (SZ) on the rotating shaft 4. Preferably, two chucks 3 are provided, each clamping one end of the rotating shaft 4. The motor 2 drives the two chucks 3 to rotate synchronously through two sets of connected belt drive devices.

[0023] The rotating shaft 4 is mounted on the chuck 3 for winding the wire 7.

[0024] The reversing guide wheel 5 is mounted on the rotating shaft 4 to reverse the direction of the wire 7 wound on the rotating shaft 4. The reversing guide wheel 5 is intersectingly connected to the rotating shaft 4 (intersecting connection means that two cylinders are connected with an intersecting line). The reversing guide wheel 5 divides the rotating shaft 4 into two sections. The section on one side of the reversing guide wheel 5 is the first section, and the section on the other side of the reversing guide wheel 5 is the second section. The direction of rotation of the wire 7 wound on the first section and the second section are different. When the motor 2 rotates forward, it is the first direction of rotation, and when the motor 2 rotates in reverse, it is the second direction of rotation, which is opposite to the first direction of rotation.

[0025] The clamp 6 has a cable routing hole 60, allowing the wire 7 to pass through and be secured in the cable routing hole 60. The wire 7 can move relative to the cable routing hole 60. When the rotating shaft 4 rotates to wind the wire 7, the wire 7 can move relative to the cable routing hole 60. When winding the wire 7, the wire 7 is pulled at the cable routing hole 60. The pulling direction of the wire 7 must be parallel to the center line of the cable routing hole 60 to prevent the wire 7 from being bent at the cable routing hole 60 of the clamp 6 and subjected to radial torque.

[0026] The mobile platform is mounted on the frame 1, and the clamp 6 is mounted on the mobile platform to drive the clamp 6 to move in a direction parallel to the axis of the rotating shaft 4. The mobile platform is an existing mobile platform, which can be a single-axis mobile platform, an XY dual-axis mobile platform, or a three-axis mobile platform. It is preferred to use an existing three-axis mobile platform so as to drive the wire to wind around the reversing guide wheel. The three-axis mobile platform can drive the clamp 6 to move along the X-axis parallel to the axis of the rotating shaft 4, the Y-axis parallel to the axis of the reversing guide wheel 5, and the Z-axis perpendicular to both the X-axis and the Y-axis. This is so that the wire 7 can be better wound around the reversing guide wheel 5 to achieve reversal before continuing to wind around the second section of the rotating shaft 4.

[0027] Reference Figure 3 The clamp 6 includes a bracket 61 and a wire-holding component 62 detachably mounted on the bracket 61. The bracket 61 is mounted on the moving platform, and the wire-passing hole 60 is located on the wire-holding component 62. After the wire 7 is wound on the second section, the wire-holding component 62 can be detached from the bracket 61 along with the wire 7, and then the wire-holding component 62 is fixed to the set position of the rotating shaft 4, thus fixing the wire 7 to the rotating shaft 4. Preferably, the wire-holding component 62 has a rubber ring 63 on the hole wall at the wire-passing hole 60 to hold the wire 7. The rubber ring 63 provides suitable friction, which can hold the wire 7 so that it does not shake freely, but does not affect the movement of the wire 7 to wind around the rotating shaft 4.

[0028] The wire clamp 62 is hinged to the bracket 61 via a hinge shaft. The axis of the hinge shaft is parallel to the axis of the rotating shaft 4. This is because when the wire 7 continues to be wound on the second section after passing around the guide wheel 5, the force direction of the wire clamp 62 is different from that when the wire 7 is wound on the first section. Therefore, the wire clamp 62 needs to be able to rotate freely around the center line of the hinge shaft by an angle to change its orientation, so that the center line of the wire hole 60 is consistent with the extraction direction of the wire 7, and adapts to the winding of the wire 7 on the second section, thereby minimizing the bending stress given by the wire clamp 62 on the wire 7.

[0029] The side wall of the rotating shaft 4 is provided with through holes 41 to lock the wire clamping member 62 after it is inserted into the through hole 41. Multiple through holes 41 are provided to accommodate wires 7 with different numbers of turns and different thicknesses. Preferably, a pair of spring pins are installed on the inner wall of the rotating shaft 4 at positions corresponding to each through hole 41 to engage and clamp the wire clamping member 62. This eliminates the need for fixing the wire 7 with materials such as adhesive tape, making the fixing of the wire 7 on the rotating shaft 4 very convenient. The wire clamping member 62 includes a U-shaped rod and a rubber ring 63 for easy insertion into the through hole 41. The rubber ring 63 is disposed inside the U-shaped rod, and the wire routing hole 60 is the inner hole of the rubber ring 63. The wire clamping member 62 on the rotating shaft 4 prevents the clamping point of the wire 7 fixed on the rotating shaft 4 from being subjected to compressive stress. The multi-hole design at the tail end of the rotating shaft 4 allows for the fixing of the tail end of the wire 7 during different winding cycles.

[0030] The first end of the rotating shaft 4 is open; a groove is provided on the side wall of the rotating shaft 4, and the groove extends through the side wall of the rotating shaft 4 to the end face of the first end of the rotating shaft 4; the end of the reversing guide wheel 5 away from the rotating shaft 4 is open, and a mounting platform is provided on the inner wall of the end of the reversing guide wheel 5 near the rotating shaft 4. A connector is mounted on the mounting platform, the connector passes through the groove, and the connector fixes the reversing guide wheel 5 and the rotating shaft 4 together. The width of the groove is relatively small, so it does not affect the normal winding of the wire 7. The connector is preferably a bolt fastening device. The groove can adapt to the position of the connector, so that the reversing guide wheel 5 can change its relative position with the rotating shaft 4 before being fixed by the connector, thereby adapting to the winding of wires 7 of various diameters, such as different winding pitches.

[0031] A limiting boss 51 is provided on the outer wall of the reversing guide wheel 5 to limit the position of the wire 7 wound on the reversing guide wheel 5. The position of the limiting boss 51 should not affect the fit of the last turn of the wire 7 wound on the first section against the outer circle of the reversing guide wheel 5, and should not hinder the reversal of the wire 7 around the reversing guide wheel 5. If the outer diameter of the wire 7 is large, it may slip off the outer circle of the reversing guide wheel 5, so the limiting boss 51 is required.

[0032] According to another aspect of the present invention, a method for bidirectional winding of wire 7 is also provided, wherein the bidirectional winding is performed using the aforementioned equipment, and includes the following steps: 1) Installing wire 7: The guide wheel 5 divides the shaft 4 into a first section and a second section. The first section is used to wind wire 7 in a first spiral direction, and the second section is used to wind wire 7 in a second spiral direction opposite to the first spiral direction. First, fix the first end of wire 7 to the first section of the shaft 4. Then, pass the second end of wire 7 through the wire routing hole 60 on the clamp 6, so that wire 7 is secured in the wire routing hole 60. Straighten the portion between the first end of wire 7 and the wire routing hole 60. Straightening this portion and preventing it from becoming loose is to ensure accurate winding on the first section. (Refer to...) Figure 1 In the top view of this device, initially, the center lines of the rotating shaft 4 and the reversing guide wheel 5 are horizontal, while the center line of the cable routing hole 60 is vertical. Except for the portion of the cable 7 wound around the rotating axial flow cylinder, the rest is vertically downward, and it remains vertically downward throughout the winding of the cable on the first section. The cable routing hole 60 is located at the intersection of the lower horizontal section of the rotating shaft 4 and the vertical section near the clamp 6.

[0033] 2) Winding wire on the first section: Motor 2 drives the rotating shaft 4 to rotate clockwise (in the first direction), and the moving platform drives the clamp 6 to move in a direction parallel to the axis of the rotating shaft 4, so that the wire 7 is wound a set number of turns on the first section of the rotating shaft 4, and the last turn of the wire wound on the first section contacts the guide wheel 5.

[0034] 3) Clamp Movement: The rotating shaft 4 pauses rotation, preferably stopping when the guide wheel 5 returns to its initial position. At this point, the centerline of the guide wheel 5 is horizontal. The moving platform continues to drive the clamp 6 to move a set stroke in a direction parallel to the axis of the rotating shaft 4, so that the wire 7 is in contact with a section of the outer arc of the guide wheel 5. This ensures that when the rotating shaft 4 reverses, the guide wheel 5 can pull the wire 7 so that the wire 7 can continue to wrap around the guide wheel 5 and then onto the second section. The arc of the section of the outer circle of the guide wheel 5 that is in contact with the wire 7 is approximately π / 4. Starting from the position where the last turn of the wire 7 contacts the guide wheel 5, the set stroke of the clamp 6 is approximately equal to the outer diameter of the guide wheel 5. If the outer diameter of the guide wheel 5 used for winding the wire 7 is equal to the outer diameter of the rotating shaft 4, both being D, then the displacement of the clamp 6 from the position where the rotating shaft 4 just paused is also D, facilitating the first turn of the wire 7 when it is wrapped around the second section of the rotating shaft 4 to contact the guide wheel 5. Of course, other displacements can be made before the shaft 4 starts to reverse and the clamp 6 continues to move. However, it is necessary to ensure that the wire 7 can be "hooked" by the guide wheel 5 and wound around the guide wheel 5, and to ensure that the first turn of the wire 7 when wound around the second section of the shaft 4 contacts the guide wheel 5.

[0035] 4) Winding the wire on the second segment: The rotating shaft 4 reverses (rotates in a second direction opposite to the first direction), and the moving platform continues to move along a direction parallel to the axis of the rotating shaft 4, so that the wire 7 is wound around the second segment a set number of times, and the first turn of the wire wound on the second segment contacts the reversing guide wheel 5; when the rotating shaft 4 just begins to reverse, the reversing guide wheel 5 also rotates around the center line of the rotating shaft 4 under the drive of the rotating shaft 4. The reversing guide wheel 5 can initially "hook" the wire 7, ensuring that the wire 7 can be wound around the reversing guide wheel 5 after it has completely reversed direction. In the second section; if the travel distance of the moving platform in step 3) is insufficient, when the reversing guide wheel 5 rotates under the drive of the rotating shaft 4, the reversing guide wheel 5 cannot "hook" the wire 7 to completely reverse its direction on the reversing guide wheel 5, or in other words, the reversing guide wheel 5 cannot "hook" the wire 7 to pull the wire 7 from the cable hole 60. Therefore, the wire 7 cannot be wound onto the second section subsequently. Thus, the travel distance of the moving platform in step 3) must be calculated in advance to ensure that the wire 7 continues to wind around the reversing guide wheel 5 before winding onto the second section when the rotating shaft 4 reverses. When the wire 7 is wound onto the second section of the rotating shaft 4, the clamping component of the clamp 6 rotates around the pivot shaft, making the center line of the cable hole 60 horizontal, thereby adapting to the winding of the wire 7 (at this time, the wire 7 is horizontal except for the section wound on the reversing guide wheel 5), preventing the wire 7 from being subjected to excessive bending stress on the clamping component. Guide holes can be set on the wire clamp to guide the wire 7 and prevent the wire 7 from becoming loose.

[0036] 5) Fixing wire 7: After removing wire 7 directly from clamp 6, fix it to the set position on the second section of rotating shaft 4, or remove the detachable wire clamp 62 of clamp 6 and fix it together with the wire 7 clamped on the wire clamp 62 to the set position on the second section of rotating shaft 4. Cut off the excess wire 7. The wire 7 wound on the second section and the wire 7 wound on the first section are symmetrically arranged on both sides of the guide wheel 5. Any two adjacent turns on the first section are in contact with each other, and any two adjacent turns on the second section are in contact with each other, that is, the turns are closely arranged together.

[0037] Reference Figure 1If the number of rotations N of the rotating shaft 4 is set by the program, it means that the wire 7 on the first segment will be wound around the rotating shaft 4 with N+0.25 turns, and the wire 7 on the second segment will be wound around the rotating shaft 4 with N-0.25 turns. When the wire 7 on the second segment is wound around the rotating shaft 4 with N-0.25 turns, the wire 7 has a horizontal length R (R is the outer diameter of the rotating shaft 4) between the tangent point of the rotating shaft 4 and the clamp 6. By continuing to rotate the rotating shaft 4 by (π-1) radians, the wire clamp 62 can be directly fixed to the through hole 41 of the rotating shaft 4 when it is removed from the clamp 6. Therefore, when the program is set to rotate the shaft 4 N times, the motor program should implement the following: the shaft 4 first rotates N times, then pauses, and after the clamp 6 moves to the other side of the guide wheel 5, the shaft should rotate N + (π-1) / 2π times. In short, the wire 7 wound on the second section should be symmetrically arranged on both sides of the guide wheel 5 with the wire 7 wound on the first section, and the wire clamp 62 should not be allowed to move relative to the wire 7 during the process of transferring to the through hole 41 of the shaft 4, so as to minimize the influence of human factors.

[0038] The present invention is mainly intended to solve the problem that human operation during the winding process of wire 7 on the rotating shaft 4 can cause damage to the sample product, such as bending stress, uneven force, and winding deformation, which leads to the failure of test results and thus affects the reliability acceptance of the sample.

[0039] This invention, through the program settings of the device's controller 8, can control the forward and reverse rotation directions of the rotating shaft 4 and the displacement distance of the clamp 6. The sample will undergo a change of direction on the rotating shaft 4, from a first-direction winding to a second-direction winding opposite to the first-direction winding. This invention, through program settings, controls the rotational speed of the rotating shaft 4 and the displacement speed and stroke of the clamp 6, enabling the sample to be wound on the rotating shaft 4 at a certain speed. This invention, by using a detachable rotating shaft 4 on the chuck 3, facilitates the clamping and disassembly of the rotating shaft 4, which is convenient for subsequent environmental testing.

[0040] This equipment can be used for the sample pretreatment stage during environmental tests such as cold bending and high-temperature aging of wire 7 (wire 7 can be optical fiber, optical fiber unit (loose tube + optical fiber or loose tube + optical fiber ribbon), small diameter optical cable). The wire 7 sample is wound bidirectionally on the rotating shaft 4 at a specified number of turns and speed to form a "sample + rotating cylinder" assembly. The assembly is placed together in the test chamber to verify the reliability of the bending performance of the wire 7 as a sample under the set environment.

[0041] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
