Description

TECHNICAL FIELD

[0001] The utility model relates to winding machine technical field, and concretely relates to a kind of slender special-shaped conductive strip quick winding insulation band mechanism. BACKGROUND

[0002] The existing manual winding slender conductive strip insulation band mode is usually as follows:

[0003] The operator will first fix the slender conductive strip in a suitable position to ensure that the conductive strip does not move randomly during winding. Then, holding one end of the insulation band, start winding along one end of the conductive strip. During winding, the winding tension of the insulation band needs to be controlled by experience and hand feeling, both to ensure tight winding and not to be too tight to cause insulation band breakage or deformation.

[0004] In order to achieve uniform winding effect, the operator will slowly rotate the conductive strip while paying attention to the overlap of the insulation band, trying to avoid gaps or excessive overlap. When approaching the other end of the conductive strip, the end portion is carefully handled to ensure that the insulation band is firm and neat.

[0005] However, this manual method has certain limitations, such as relatively low efficiency, winding quality is easily affected by operator skills and state, and long-time operation may cause fatigue, affecting work precision. INVENTION CONTENTS

[0006] In order to overcome the above technical problems, the utility model provides a kind of slender special-shaped conductive strip quick winding insulation band mechanism to improve the various drawbacks of manual winding.

[0007] In order to achieve the above purpose, the utility model provides a kind of slender special-shaped conductive strip quick winding insulation band mechanism, including workbench and track moving table, the track moving table is fixed with support plate, the support plate is installed with winding wheel and drive assembly that drives winding wheel rotation, the winding wheel is equipped with multiple over-rollers arranged on the circumferential plane of the winding wheel, which can buffer winding insulation band, the top of the support plate is installed with a material roll wheel that provides insulation band, the support plate is fixedly installed with a front compression assembly located outside one side of the over-roller end portion, and a rear compression assembly fixed with the support plate located outside one side of the winding wheel away from the over-roller.

[0008] A winding wheel is installed on a support plate. The conductive strip to be wound passes through the middle of the winding wheel, which rotates under the drive of the drive assembly. An insulating tape is provided by a feed roll, which passes through the gap between adjacent rollers and wraps around the conductive strip. As the winding wheel rotates, the insulating tape wraps around the outside of multiple rollers as a buffer. When the buffer amount is sufficient to wrap the entire conductive strip, the insulating tape is cut, and the conductive strip is then wound around by the insulating tape wrapped around the outside of the rollers.

[0009] Preferably, the drive assembly includes a drive motor and a drive gear mounted on the working end of the drive motor, and the outer periphery of the winding wheel has teeth that mesh with the drive gear.

[0010] Under the control of the electronic control device, the drive motor drives the winding wheel to rotate. The drive gear meshes with the teeth formed on the winding wheel, which can precisely control the number of rotations and the rotation speed of the winding wheel.

[0011] Preferably, the winding wheel is equipped with an angle adjusting rod capable of adjusting the winding angle of the insulating tape.

[0012] The purpose of setting the adjusting rod is to adjust the position of the overlapping edges of the insulating tape, as well as the angle between the insulating tape and the conductive strip being wound during winding, to ensure that the winding process is uniform and balanced.

[0013] Preferably, a first steel strip pressure plate is fixed above one side of the winding wheel on the support plate, and a tensioning assembly is provided above the other side of the winding wheel. A flexible steel strip is connected to the steel strip pressure plate. The flexible steel strip extends from the bottom of the winding wheel and wraps around the outside of the plurality of rollers, and the end of the flexible steel strip is connected to the tensioning assembly 4.

[0014] The flexible steel strip wraps around the bottom of multiple rollers from the outside. One end is fixed to the first steel strip pressure plate, and the other end is connected to the tensioning assembly. The tensioning force generated by the tensioning assembly pulls the flexible steel strip, so that it can fit tightly against the outside of the rollers. This allows the insulating tape buffered on the rollers to be pressed tightly. During the winding of the conductive strip, the insulating tape can be taut, thus ensuring the winding quality.

[0015] Preferably, the support plate is located below the material roll reel and is fixed with a shearing device that is opposite to the position of the insulating tape.

[0016] The function of the shearing device is to directly cut the insulating tape when there is enough insulating tape buffered on the winding wheel. This is done entirely by program control without manual intervention, with precise calculations, thus reducing the waste of insulating tape.

[0017] Preferably, the end of the roller is fixed with an outer baffle that is parallel to the winding wheel.

[0018] The purpose of setting the outer baffle is to prevent the insulating tape from falling off the end of the roller during winding and to prevent it from deviating under the pressure of the flexible steel strip.

[0019] Preferably, the front clamping assembly includes a fixing member fixed to the support plate, a telescopic cylinder capable of sliding along the fixing member is mounted on the fixing member, a clamping cylinder is mounted on the telescopic cylinder, and a first clamping wheel is provided on the working end of the clamping cylinder.

[0020] The fixing component serves as the base for the front clamping assembly, supporting the entire structure and ensuring the normal operation of other components. The telescopic cylinder can drive the clamping cylinder to achieve displacement, thereby winding conductive strips with different structures and positions. The clamping cylinder drives the first clamping wheel to tighten the conductive strip, preventing it from shaking and making the winding of the insulating tape more stable.

[0021] Preferably, the rear clamping assembly includes a pressing cylinder fixed to the support plate, a second clamping wheel is provided on the working end of the pressing cylinder, a clamping bracket is fixed on the support plate, and a third clamping wheel is provided on the clamping bracket opposite to the position of the second clamping wheel.

[0022] The downward-pressing cylinder drives the second pressing wheel to move downward, opposite to the third pressing wheel, clamping the conductive strip between them. Together with the first pressing wheel, the position where the conductive strip is wound is fixed between the first pressing wheel, the second pressing wheel, and the third pressing wheel. The pressed position can remain stable, so that the winding process will not deviate.

[0023] Preferably, the tensioning assembly includes a mounting base fixed to the support plate, a guide shaft fixed on the mounting base, a spring sleeved on the guide shaft, and a sliding seat sleeved on the guide shaft and in contact with the end of the spring. A second steel strip pressure plate is fixed on the sliding seat, and the end of the flexible steel strip is fixed to the second steel strip pressure plate.

[0024] The mounting base is used to fix the guide shaft, allowing the sliding seat to slide stably on the guide shaft. Under the elastic force of the spring, the sliding seat drives the second steel strip pressure plate to move towards the end of the guide shaft. The second steel strip pressure plate is connected to the end of the flexible steel strip, pulling the flexible steel strip taut so that it can press the insulating tape wrapped on the winding wheel tightly, ensuring the winding effect.

[0025] Preferably, the shearing device includes a pneumatic shear fixing seat fixed to the support plate, a blade slidably connected to the pneumatic shear fixing seat, and a thrust cylinder fixed to the pneumatic shear fixing seat with its working end connected to the blade and capable of pushing the blade to slide back and forth.

[0026] The pneumatic shear holder serves as a fixing device to ensure the smooth sliding of the blade, while the working end of the thrust cylinder is connected to the blade. Under the control of the controller, the blade completes the shearing work on the insulating tape.

[0027] This utility model provides a mechanism for quickly winding slender, irregularly shaped conductive strips with insulating tape. It solves the problems of tedious and inefficient manual winding of such strips, which is difficult due to their slender shape. Furthermore, the tightness of the wound insulating tape is uncontrollable, and the thickness and width of the finished product cannot be controlled. This application employs a flexible adjustment method, compatible with multiple products. After the product is placed and fixed, only two initial manual wraps are required before automatic winding begins. The overlap rate and winding speed can be freely set, effectively reducing the time cost of manual winding and improving the dimensional accuracy of the wound product. Attached Figure Description

[0038] Embodiments of the present invention will now be described with reference to the accompanying drawings. Elements and features described in one drawing or embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that, for clarity, representations and descriptions of components or processes unrelated to the present invention and known to those skilled in the art have been omitted from the drawings and description.

[0039] The present invention will now be further described with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the slender, irregularly shaped conductive strip rapid winding insulating tape mechanism provided by this utility model includes a worktable 1 and a track moving platform 2. A support plate 3 is fixed on the track moving platform 2. A winding wheel 4 and a drive assembly for driving the winding wheel 4 to rotate are installed on the support plate 3. The winding wheel 4 is provided with multiple rollers 5 arranged in the circumferential direction of the plane of the winding wheel 4 to buffer the winding insulating tape. A material roll 6 for providing insulating tape is installed on the top of the support plate 3. A front pressing assembly 7 located outside one side of the end of the roller 5 and a rear pressing assembly 8 fixed to the support plate 3 and located outside the side of the winding wheel 4 away from the roller 5 are also fixed to the support plate 3.

[0041] A winding wheel 4 is installed on the support plate 3. The conductive strip to be wound passes through the middle of the winding wheel 4. The winding wheel 4 rotates under the drive of the drive assembly. The material roll 6 provides insulating tape, which passes through the gap between adjacent guide rollers 5 and is wound around the conductive strip. When the winding wheel 4 rotates, the insulating tape is wound around the outside of multiple guide rollers 5 as a buffer. When the buffer amount is sufficient to wind the entire conductive strip, the insulating tape is cut, and the conductive strip is wound around the outside of the guide rollers 5.

[0042] Before winding the insulating strip, the end of the insulating tape is first wrapped around the conductive strip one and a half to two turns to determine the initial position. Under the control of the controller, the drive assembly drives the winding wheel 4 to rotate, and a portion of the insulating tape begins to wind along the length of the conductive strip, while the remaining portion is wound around the outside of multiple guide rollers 5 as a buffer. When the program calculates that the buffer has enough insulating tape to wind the entire conductive strip, the insulating tape below the material roll 6 is cut off, and the remaining portion is wound around the outside of the multiple guide rollers 5 as the winding wheel 4 rotates.

[0043] The insulating tapes are stacked on top of each other, but the resistance of the insulating tapes rubbing against each other is very small. They are continuously wrapped around the surface of the conductive strip through the gap between the rollers 5. At the same time, under the control of the controller, the track moving table 2 gradually moves forward along the track to cover and wrap the surface of the conductive strip fixed on the worktable 1 until the wrapping is completed.

[0044] In one embodiment of the present invention, the driving assembly includes a driving motor 9 and a driving gear 10 mounted on the working end of the driving motor 9. A toothed opening 11 is formed on the outer periphery of the winding wheel 4, and the toothed opening 11 meshes with the driving gear 10.

[0045] Under the control of the electronic control device, the drive motor 9 drives the winding wheel 4 to rotate. The drive gear 10 meshes with the teeth 11 formed on the winding wheel 4, which can precisely control the number of rotations and the rotation speed of the winding wheel 4.

[0046] The drive motor 9 is directly connected to the controller, which controls the number of rotations and the rotation speed, thereby driving the winding wheel 4 to rotate and accurately complete the overall winding work.

[0047] In one embodiment of this utility model, an angle adjustment rod 12 capable of adjusting the winding angle of the insulating tape is installed on the winding wheel 4.

[0048] The purpose of setting the adjusting rod is to adjust the position of the overlapping edges of the insulating tape, as well as the angle between the insulating tape and the conductive strip being wound during winding, to ensure that the winding process is uniform and balanced.

[0049] In one embodiment of this utility model, a first steel strip pressure plate 13 is fixed on the support plate 3 above one side of the winding wheel 4, and a tensioning assembly 14 is provided above the other side of the winding wheel 4. A flexible steel strip 15 is connected to the steel strip pressure plate. The flexible steel strip 15 extends from the bottom of the winding wheel 4 and wraps around the outside of the multiple rollers 5. The end of the flexible steel strip 15 is connected to the tensioning assembly 14.

[0050] The flexible steel strip 15 wraps around the bottom of multiple rollers 5 from the outside. One end is fixed to the first steel strip pressure plate 13, and the other end is connected to the tensioning assembly 14. The tensioning force generated by the tensioning assembly 14 pulls the flexible steel strip 15 so that it can fit tightly against the outside of the rollers 5, thereby pressing the insulating tape buffered on the rollers 5. During the winding of the conductive strip, the insulating tape can be tightened, thereby ensuring the winding quality.

[0051] Of course, the flexible steel strip 15 can also be replaced with other flexible materials, such as nylon strip, rubber strip, etc. Its main function is to press the insulating strip wrapped around the outside of the roller 5 so that it is in a taut state.

[0052] In one embodiment of this utility model, a shearing device 16 is fixed to the support plate 3 below the material roll 6, which is opposite to the position of the insulating tape.

[0053] The function of the shearing device 16 is to directly cut the insulating tape when there is enough insulating tape buffered on the winding wheel 4, without manual intervention. It is completely controlled by the program, with accurate calculation and reduced waste of insulating tape.

[0054] In one embodiment of this utility model, an outer baffle 17 is fixed at the end of the roller 5 and is arranged parallel to the winding wheel 4.

[0055] The purpose of setting the outer baffle 17 is to prevent the insulating tape from falling off the end of the roller 5 during winding and to prevent it from deviating under the pressure of the flexible steel strip 15.

[0056] In one embodiment of the present invention, the front clamping assembly 7 includes a fixing member 18 fixed to the support plate 3. A telescopic cylinder 19 capable of sliding along the fixing member 18 is installed on the fixing member 18. A clamping cylinder 20 is installed on the telescopic cylinder 19. A first clamping wheel 21 is provided on the working end of the clamping cylinder 20.

[0057] The fixing component 18 serves as the base for the front clamping assembly 7, supporting the entire structure and ensuring the normal operation of other components. The telescopic cylinder 19 can drive the clamping cylinder 20 to achieve displacement, thereby winding conductive strips with different structures and positions. The clamping cylinder 20 drives the first clamping wheel 21 to tighten the conductive strip, preventing the conductive strip from shaking and making the winding process of the insulating tape more stable.

[0058] In one embodiment of the present invention, the rear clamping assembly 8 includes a pressing cylinder 22 fixed to the support plate 3. A second clamping wheel 23 is provided on the working end of the pressing cylinder 22. A clamping bracket is fixed on the support plate 3. A third clamping wheel 24 is provided on the clamping bracket, which is positioned opposite to the second clamping wheel 23.

[0059] The downward pressing cylinder 22 drives the second pressing wheel 23 to move downward, opposite to the third pressing wheel 24, clamping the conductive strip between them. Together with the first pressing wheel 21, the position where the conductive strip is wound is fixed between the first pressing wheel 21, the second pressing wheel 23, and the third pressing wheel 24. The pressed position can remain stable, so that the winding process will not deviate.

[0060] In one embodiment of this utility model, the tensioning assembly 14 includes a mounting base 25 fixed to the support plate 3, a guide shaft 26 fixed to the mounting base 25, a spring 27 sleeved on the guide shaft 26, and a sliding seat 28 sleeved on the guide shaft 26 and in contact with the end of the spring 27. A second steel strip pressure plate 29 is fixed on the sliding seat 28, and the end of the flexible steel strip 15 is fixed to the second steel strip pressure plate 29.

[0061] Mounting base 25 is used to fix guide shaft 26, allowing sliding base 28 to slide stably on guide shaft 26. Under the elastic force of spring 27, sliding base 28 drives second steel strip pressure plate 29 to move towards the end of guide shaft 26. Second steel strip pressure plate 29 is connected to the end of flexible steel strip 15, pulling and tightening flexible steel strip 15 so that flexible steel strip 15 can press tightly against the insulating tape wound on winding wheel 4, ensuring winding effect.

[0062] In one embodiment of this utility model, the shearing device 16 includes a pneumatic shear fixing seat 30 fixed to the support plate 3, a blade 32 slidably connected to the pneumatic shear fixing seat 30, and a thrust cylinder 31 fixed to the pneumatic shear fixing seat 30 with its working end connected to the blade 32 and capable of pushing the blade 32 to slide back and forth.

[0063] The air shear fixing seat 30 serves as a fixing device to ensure the smooth sliding of the blade 32, while the working end of the thrust cylinder 31 is connected to the blade 32. Under the control of the controller, the blade 32 completes the shearing work of the insulating tape.

[0064] This utility model provides a mechanism for quickly winding slender, irregularly shaped conductive strips with insulating tape. It solves the problems of tedious and inefficient manual winding of such strips, which is difficult due to their slender shape. Furthermore, the tightness of the wound insulating tape is uncontrollable, and the thickness and width of the finished product cannot be controlled. This application employs a flexible adjustment method, compatible with multiple products. After the product is placed and fixed, only two initial manual wraps are required before automatic winding begins. The overlap rate and winding speed can be freely set, effectively reducing the time cost of manual winding and improving the dimensional accuracy of the wound product.

[0065] While the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention as defined by the appended claims. Furthermore, the scope of this application is not limited to the specific embodiments of the processes, apparatus, means, methods, and steps described in the specification.
