Description

Technical Field

[0001] This invention relates to the field of wrapping machines, and more particularly to a wrapping machine. Background Technology

[0002] The U-shaped primary conductor is a component of high-voltage power transformers in the power manufacturing industry. It is a hollow copper or aluminum tube conductor bent into a U shape, with two vertical arms. One end of each of the two vertical arms is connected by an arc bend. The distance between the two ends of the arc bend is greater than the distance between the two vertical arms. Therefore, the connection between the arc bend and the two vertical arms is transitioned by an inclined section. The free ends of the two vertical arms are terminals.

[0003] The U-shaped primary conductor needs to be wrapped with cable paper, which is then wrapped around the U-shaped primary conductor in a spiral, semi-overlapping manner. The current method involves manually pulling the wrapping head along the U-shaped primary conductor, with the cable paper being wrapped around its exterior. However, this method is inefficient, and the final outer diameter of the conductor after wrapping the cable paper cannot be guaranteed to be consistent, thus affecting the quality of the cable paper wrapping on the primary conductor. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic cable wrapping machine that can guarantee wrapping quality.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a wrapping machine, comprising:

[0006] Base;

[0007] A lifting platform is installed at one end of the base;

[0008] Multiple support components, each with an adjustable height, are installed at the other end of the base. The lifting platform and support components work together to support the U-shaped primary conductor, keeping it in a horizontal position.

[0009] The winding unit includes:

[0010] The base plate is slidably mounted on the upper surface of the base via an X-axis guide rail pair and is driven to move back and forth in the X-axis direction by a first X-axis drive source.

[0011] A rotary table is slidably mounted on the upper surface of the base plate via a Y-axis guide rail pair and is driven by a Y-axis drive source to move back and forth in the Y-axis direction. The length of the Y-axis guide rail pair is greater than the maximum width of the U-shaped primary conductor.

[0012] A winding head is fixedly installed on the upper surface of a rotating table. The winding head is circular in shape. The U-shaped primary conductor passes through the winding head. A horizontal diameter measuring module and a vertical diameter measuring module are provided on the rear side of the winding head.

[0013] The first X-axis drive source, Y-axis drive source, and rotary drive source work together to drive the winding head to reciprocate around the U-shaped primary conductor to wrap the cable paper. When the winding head passes any support component, the support component can descend and tilt outward to make way.

[0014] The beneficial effects of the wrapping machine of this invention are:

[0015] Firstly, in this application, after the U-shaped primary conductor is supported by a lifting platform and multiple support components, the winding head reciprocates around the U-shaped primary conductor to wrap the cable paper through the combined action of the first X-axis drive source, Y-axis drive source, and rotary drive source. After the lifting platform supports the U-shaped primary conductor, it always supports it without giving way until the cable paper is wrapped. The other end of this application is supported by multiple support components. When the winding head passes any support component, the corresponding support component can descend and tilt outward to give way, allowing the winding head to wrap the cable paper. The remaining support components continue to provide support, and the winding operation will not be affected by the setting of the support components.

[0016] Secondly, the winding head of this application is fixedly installed on the rotating table. The path of the winding head can be preset according to the shape of the U-shaped primary conductor, so that the winding head can automatically wrap the cable paper along the outer diameter of the winding machine. Compared with manually holding the winding head along the U-shaped primary conductor, the thickness of each section can be consistent, and the outer diameter of the workpiece after winding is consistent.

[0017] Thirdly, the rotary table of this application is slidably mounted on the upper surface of the base plate via a Y-axis guide rail pair, and the length of the Y-axis guide rail pair is greater than the maximum width of the U-shaped primary conductor. The winding head is fixedly mounted on the upper surface of the rotary table. When the Y-axis drive source drives the rotary table to move to the outermost part of the Y-axis guide rail pair, the winding head moves synchronously to the maximum width of the U-shaped primary conductor and wraps the part with the maximum width of the U-shaped primary conductor. When the Y-axis drive source drives the rotary table to move closer to the center position of the Y-axis guide rail pair, the winding head wraps the part with the narrower part of the U-shaped primary conductor, realizing the winding operation of the wide and narrow parts by one winding head.

[0018] Fourth, this application utilizes horizontal and vertical diameter measuring modules to detect the thickness of the U-shaped primary conductor after the cable paper is wrapped, ensuring product quality. Furthermore, the horizontal and vertical diameter measuring modules move with the wrapping head to inspect the wrapped workpiece. If any problems are found, timely feedback and correction can be provided, thus improving the wrapping quality.

[0019] Preferably, the lifting platform includes:

[0020] The translation frame is connected at its bottom to the X-axis guide rail pair;

[0021] The lifting platform is mounted above the translation frame and can be raised and lowered via multiple guide columns.

[0022] Two support plates are fixedly installed on the top of the lifting plate and extend out of the lifting plate, respectively used to support the two ends of the same end of the U-shaped primary conductor;

[0023] The servo electric cylinder has its cylinder body fixedly mounted longitudinally on the translation frame, and its piston rod is connected and fixed to the bottom of the lifting plate.

[0024] The above uses a servo electric cylinder to drive the lifting plate to rise and fall, so that the lifting plate can stop at any height, and the height of the two support plates can be adjusted to adapt to U-shaped primary conductors of different diameters wrapped with cable paper.

[0025] Preferably, the lifting platform is slidably mounted on the upper surface of the base via the X-axis guide rail pair and is driven to reciprocate by a second X-axis drive source. The position of the lifting platform in the X-axis direction of the base can be adjusted according to the length of different U-shaped primary conductors, making it adaptable to workpieces of different lengths.

[0026] Preferably, both the first X-axis drive source and the second X-axis drive source include:

[0027] X-axis rack, the upper end face of the base is provided with a slot in the middle, two X-axis racks are installed on opposite sides of the slot, and the tooth structure of the two X-axis racks is arranged opposite to each other;

[0028] An X-axis servo motor is fixedly mounted on the translation frame of the base plate or lifting platform and extends into the slot;

[0029] The X-axis drive gear is fixedly mounted on the output shaft of the X-axis servo motor, and the X-axis drive gear meshes with the X-axis rack.

[0030] A cable chain, one end of which is fixedly mounted to the bottom of the base plate or translation frame, is used to carry the cable of the X-axis servo motor.

[0031] With the above solution, since the base has a slot in the middle and the two X-axis racks are installed on opposite sides of the slot, and the tooth structure of the two X-axis racks is arranged opposite each other, the winding unit and the lifting platform can be installed in the slot in an embedded design, which reduces the overall footprint of the winding machine; the X-axis drive gear is driven to rotate by the X-axis servo motor, and through cooperation with the X-axis rack, the base plate or translation frame is forced to move back and forth along the X-axis guide rail pair; the cable chain is used to store the servo motor related wires since the X-axis servo motor of this application moves back and forth.

[0032] Preferably, the rotary table includes:

[0033] The support platform is driven by the Y-axis drive source to move back and forth on the Y-axis guide rail pair;

[0034] The first external tooth slewing bearing includes a fixed outer ring with external teeth and a rotating inner ring that rotatably engages with the fixed outer ring. The fixed outer ring is fixedly installed on the upper surface of the support platform.

[0035] A rotating plate is fixedly installed on the upper end face of the rotating inner ring, and the wrapping head is fixedly installed on the upper end face of the rotating plate;

[0036] A rotary servo motor is fixedly mounted on the rotating plate;

[0037] A rotary drive gear is fixedly mounted on the output shaft end of the rotary servo motor and meshes with the outer teeth of the fixed outer ring.

[0038] The rotary drive gear is driven by a rotary servo motor. Since the rotary drive gear meshes with the outer teeth of the fixed outer ring, and the rotary plate is fixedly installed on the inner rotating ring, the rotary plate will rotate accordingly, thereby driving the rotating head to rotate.

[0039] More preferably, a protective cover is provided on the lower end face of the rotating plate, the protective cover being used to surround the rotary drive gear and the first external tooth slewing bearing.

[0040] Preferably, the Y-axis drive source includes:

[0041] The Y-axis rack is fixedly installed at the bottom of the rotary table;

[0042] The Y-axis servo motor is fixedly mounted on the base plate;

[0043] The Y-axis drive gear is fixedly installed at the end of the output shaft of the Y-axis servo motor and meshes with the Y-axis rack.

[0044] Preferably, each of the support components includes:

[0045] Two limiting plates are provided, which are parallel to each other and perpendicular to the horizontal plane. Corresponding rack longitudinal slides are provided on the two limiting plates. On the outer side of the rack longitudinal slides, there are vertically distributed connecting rod obtuse angle slides and a lower connecting rod longitudinal slide parallel to the rack longitudinal slides. The connecting rod obtuse angle slides include an upper connecting rod longitudinal slide integrally formed and an inclined slide. The upper connecting rod longitudinal slide is located directly above the lower connecting rod longitudinal slide, and their central axes coincide. The inclined slide is inclined downward.

[0046] A vertically arranged lifting rack is provided with rack guide rollers on both sides of the upper and lower ends of the lifting rack, and the rack guide rollers on both sides are slidably embedded in two longitudinal rack slides respectively.

[0047] The movable link has its lower end rotatably connected to the lower end of the lifting rack. Both sides of the lower end of the movable link are provided with upper guide rollers and lower guide rollers. The upper guide rollers are slidably embedded in the obtuse-angle slide rails of the link, and the lower guide rollers are slidably embedded in the longitudinal slide rails of the lower link.

[0048] A support rod, which is adjustablely mounted on top of the movable link;

[0049] A supporting servo motor is provided, the output shaft of which is connected to a driving lifting gear, and the driving lifting gear meshes with a lifting rack.

[0050] The sensor group includes an upper sensor and a lower sensor, which are respectively installed at the upper limit position and the lower limit position of the lifting rack.

[0051] By coordinating the rack longitudinal slide, connecting rod obtuse angle slide, and lower connecting rod longitudinal slide on the two limit plates, the lifting rack can be raised and lowered, and the movable connecting rod can be raised and lowered and rotated once the servo motor drives it. The structure is simple and the design is ingenious. The upper and lower sensors are used to limit the extreme positions of the lifting rack.

[0052] Preferably, the upper end of the movable connecting rod is provided with a sleeve, the support rod is inserted into the sleeve, and the sleeve is provided with a bolt for locking the support rod. The length of the support rod is telescopic; if telescopic extension or retraction is required, the bolt is loosened, the position of the support rod within the sleeve is adjusted, and the length of the support rod can be adjusted. Once adjusted, the bolt is locked.

[0053] Preferably, the wrapping head includes:

[0054] A fixed base is longitudinally fixedly installed on the upper end face of the rotating plate of the rotary table;

[0055] The second external tooth slewing bearing includes a metal rotating outer ring with external teeth and a fixed inner ring, wherein the fixed inner ring is fixedly mounted on a fixed base;

[0056] A rotating ring is fixedly installed on the front side of the metal rotating outer ring. It includes two rotating plates and a number of guide bearings for connecting the two rotating rings. The free end of the cable paper passes between two adjacent rollers and is wound around the U-shaped primary conductor. The cable paper can be wound around the number of guide bearings.

[0057] The servo motor is fixedly mounted on a fixed base, and its output shaft is fixedly connected to a nylon drive gear, which meshes with the outer teeth of a metal rotating outer ring. The combination of nylon and metal materials is used to reduce the generation of metal shavings, because generally the drive gear and the rotating outer ring are made of iron. If the two are in contact for a long time, iron shavings will be generated, which will ultimately affect the quality of the product.

[0058] At least two feeding trays are installed on a tray frame. The tray frame is slidably installed on the top of a fixed base via a tray guide rail pair. A tray cylinder is provided on the top of the fixed base. The tray cylinder drives the tray frame to move back and forth. Any one of the feeding trays can move to directly above the rotating ring.

[0059] The inner and outer through-beam sensor groups are fixedly mounted on a fixed base. When there is no material on the wrapping rotating ring, the inner and outer through-beam sensor groups detect each other. When there is material on the wrapping rotating ring, the inner through-beam sensor group disconnects its detection. When the wrapping rotating ring is full of material, the outer through-beam sensor group disconnects its detection.

[0060] A guide block is located on the front side of the fixed base between the wrapping rotating ring and the feeding tray, and the cable paper passes through the guide block;

[0061] A scissor assembly, mounted on the rear side of the guide block, cuts the cable paper passing through the guide block when the external photoelectric sensor group disconnects from the photoelectric connection.

[0062] The tensioning assembly includes a tensioning servo motor and a belt. One end of the belt is fixed to a fixed base, the tensioning servo motor is fixedly mounted on the fixed base, and the other end of the belt is fixed to the output shaft end of the tensioning servo motor. The belt presses and wraps around at least a portion of the cable paper on the rotating ring.

[0063] Because this application adopts the above-mentioned technical solution, a wrapping rotating ring is formed by two rotating plates and several guide bearings. The cable paper is fed from between the two guide bearings of the feeding tray and finally wrapped around the U-shaped primary conductor. When the nylon drive gear of the wrapping servo motor drives the metal rotating outer ring to rotate, the cable paper will also be wrapped around one of the guide bearings of the rotating wrapping ring as the wrapping rotating ring wraps around the U-shaped primary conductor through the central hole of the wrapping rotating ring. This process continues until the wrapping rotating ring is fully wrapped. The external through-beam sensor senses that the material is full and cuts the cable paper that has passed through the guide block. After the cable paper on the wrapping rotating ring is completely wrapped around the U-shaped primary conductor, the cable paper on the feeding tray is passed through the wrapping rotating ring and wrapped around the U-shaped primary conductor. This process is repeated continuously. This application uses two feeding trays. Once the first feeding tray has completely fed the cable paper to the winding rotating ring, the feeding tray cylinder moves the next feeding tray to directly above the winding rotating ring. The second feeding tray then feeds the winding rotating ring, which can continuously feed the winding rotating ring to a certain extent. The servo motor drives one end of the belt to rotate, so that the belt is tightly wrapped around the cable paper on the winding rotating ring, ensuring the tension of the cable paper wrapped around the U-shaped primary conductor.

[0064] Preferably, the horizontal diameter measuring module and the vertical diameter measuring module are installed in a configuration that includes:

[0065] A linear motion assembly includes two synchronous pulleys rotatably mounted on the fixed base, a synchronous belt sleeved on the two synchronous pulleys, a diameter measuring servo motor for driving one of the synchronous pulleys to rotate, a slide table fixedly connected to the synchronous belt, the slide table being slidably disposed on the rear side of the fixed base via a slide rail, and the diameter measuring servo motor being fixedly mounted on the fixed base.

[0066] A diameter measuring sensor is fixedly mounted on the slide table;

[0067] The two linear motion groups are perpendicular to each other. The diameter measuring sensor of the horizontal diameter measuring module is set in the horizontal direction, and the diameter measuring sensor of the vertical diameter measuring module is set in the vertical direction, in order to detect whether the U-shaped primary conductor after being wrapped with cable paper has reached the required thickness.

[0068] The position of the diameter measuring sensor is pre-set according to the different sizes of U-shaped primary conductors and the thickness of the cable paper to be wrapped around them. The diameter measuring servo motor drives the diameter measuring sensor to the required set position to measure the diameter of the U-shaped primary conductor wrapped with cable paper in the horizontal and vertical directions.

The laser calibration parts 451b are used to mark the U-shaped primary conductor wrapped with cable paper with laser labels. The U-shaped primary conductor also needs to be manually wrapped during the process of wrapping the cable paper. Manual wrapping refers to manually wrapping the shielding paper / shielding foil and then wrapping the cable paper. The laser calibration parts 451 mark the positions where manual wrapping is required to facilitate the manual wrapping later.

[0129] The second external tooth slewing bearing 452 includes a metal rotating outer ring 452a with external teeth and a fixed inner ring 452b, with the fixed inner ring 452b fixedly mounted on the fixed base 451.

[0130] The rotating ring 453 is fixedly installed on the front side of the metal rotating outer ring 452a. It includes two rotating plates 453a and a number of guide bearings 453b for connecting the two rotating rings 453. The free end of the cable paper 610 passes between two adjacent rollers and is wound on the U-shaped primary conductor 600. The cable paper 610 can be wound on the number of guide bearings 453b.

[0131] The servo motor 454 is fixedly mounted on the fixed base 451, and its output shaft is fixedly connected to the nylon drive gear 454a. The nylon drive gear 454a meshes with the outer teeth of the metal rotating outer ring 452a to reduce iron filings, which in turn affect the product.

[0132] At least two feeding trays 455 are installed on a tray frame 455a. The tray frame 455a is slidably installed on the top of the fixed base 451 via a tray guide rail pair 451a. A tray cylinder 455b is provided on the top of the fixed base 451. The tray cylinder 455b drives the tray frame 455a to move back and forth. Any one of the feeding trays 455 can move to be directly above the rotating ring 453.

[0133] The inner through-beam sensor group 456a and the outer through-beam sensor group 456b are fixedly installed on the fixed base 451. When there is no material on the rotating ring 453, the inner through-beam sensor group 456a and the outer through-beam sensor group 456b are inductively connected. When there is material on the rotating ring 453, the inner through-beam sensor group 456a disconnects its inductive connection. When the rotating ring 453 is full of material, the outer through-beam sensor group 456b disconnects its inductive connection.

[0134] Guide block 457 is located in front of fixed base 451 between rotating ring 453 and feeding plate 455, and cable paper 610 passes through guide block 457;

[0135] The scissor assembly 458 is installed on the rear side of the guide block 457. When the external photoelectric sensor group 456b disconnects the photoelectric transmission, the scissor assembly 458 will cut the cable paper 610 passing through the guide block 457.

[0136] The tension assembly 459 includes a tension servo motor 459a and a belt 459b. One end of the belt 459b is fixed to the fixed base 451. The tension servo motor 459a is fixedly mounted on the fixed base 451. The other end of the belt 459b is fixed to the output shaft end of the tension servo motor 459a. The belt 459b presses against at least a portion of the cable paper 610 on the rotating ring 453.

[0137] like Figure 8 , Figure 12 As shown, the horizontal diameter measuring module 420a and the vertical diameter measuring module 420b are installed in each of the following:

[0138] The linear motion assembly includes two synchronous pulleys 421 rotatably mounted on a fixed base 451, a synchronous belt 422 sleeved on the two synchronous pulleys 421, a diameter measuring servo motor 423 for driving one of the synchronous pulleys 421 to rotate, a slide 424 fixedly connected to the synchronous belt 422, the slide 424 being slidably disposed on the rear side of the fixed base 451 via a slide rail, and the diameter measuring servo motor 423 being fixedly mounted on the fixed base 451.

[0139] The diameter measuring sensor 425 is fixedly mounted on the slide table 424;

[0140] The two linear motion groups are perpendicular to each other. The diameter measuring sensor 425 of the horizontal diameter measuring module 420a is set in the horizontal direction, and the diameter measuring sensor 425 of the vertical diameter measuring module 420b is set in the vertical direction. They are used to detect whether the U-shaped primary conductor 600 after wrapping the cable paper 610 has reached the required thickness.

[0141] The working principle of this embodiment is as follows:

[0142] The lifting platform 200 and multiple support components 300 are pre-raised to almost the same height. The U-shaped primary conductor 600 is hoisted by a crane to the winding head 450 that passes through the winding unit 400. The two ends of the U-shaped primary conductor 600 are supported by the lifting platform 200 at one end and multiple support components 300 at the other end. The U-shaped primary conductor 600 can be made to be in a completely horizontal state by fine-tuning the servo cylinder 240 and the support servo motor 350.

[0143] The first X-axis drive source 500a drives the winding head 450 to move to the first end of the U-shaped primary conductor 600. Since the same end of the U-shaped primary conductor 600 is supported by two support plates 230, the winding head 450 can retract to the support plate 230, thus not affecting the winding operation of the winding head 450 on the U-shaped primary conductor 600. According to the shape of the U-shaped primary conductor 600, the distance the first X-axis drive source 500a drives the winding head 450 forward and the angle of rotation of the rotary table 430 are preset to coordinate with the on-site sensor winding operation.

[0144] When wrapping cable paper, the wrapping head 450 travels along the path of the U-shaped primary conductor 600. The free end of the cable paper is pulled from the feed tray 455 to the guide block 457, passes through the middle of the guide block 457, and is pulled towards the wrapping rotating ring 453. It then exits through the two guide bearings 453b of the wrapping rotating ring 453, and the free end of the cable paper is wrapped around the U-shaped primary conductor 600 at a certain angle. When the wrapping servo motor 454 is started, it drives the metal rotating outer ring 452a to rotate through the nylon drive gear 454a, which in turn drives the wrapping rotating ring 453 to rotate, and the cable paper spiral is wrapped around the U-shaped primary conductor 600. Because the diameter of the U-shaped primary conductor 600 is small, and the diameter formed by the guide bearing 453b surrounding the rotating ring 453 is large, when the rotating ring 453 rotates once, less cable paper is consumed on its inner side. The cable paper on the tray 455 is continuously stored on the guide bearing 453b surrounding the rotating ring 453 until it is full. The two adjacent rings of stored cable paper are not completely pressed together. When the outer through-beam sensor group 456b is full, it is cut by the scissor assembly 458. While waiting for all the cable paper on the rotating ring 453 to be wrapped around the U-shaped primary conductor 600, the tension servo motor 459a adjusts the tension of the belt 459b in real time to make it adhere to the cable paper stored on the rotating ring 453, ensuring the tension of the cable paper wrapped around the U-shaped primary conductor 600.

[0145] Sensors are installed on the top of each support component 300 to detect whether the wrapping head 450 has moved to the support component 300. Once the wrapping head 450 is detected, the support servo motor 350 of the support component 300, which is connected to the sensor, drives the lifting gear 351 to rotate, which in turn drives the lifting rack 320 to descend. Since the lower end of the movable link 330 is rotatably connected to the lower end of the lifting rack 320, the movable link 330 descends accordingly. The upper guide roller 331 of the link slides along the obtuse angle slide 312 of the link, and the lower guide roller 332 slides down along the longitudinal slide 313 of the lower link. The movable link 330 as a whole first descends along the longitudinal slide 312a of the upper link, and then tilts outward along the inclined slide 312b, so that the support rod 340 descends and expands outward, making room for the wrapping head 450 to perform the wrapping operation on the U-shaped primary conductor 600.

[0146] As the wrapping head 450 travels around the U-shaped primary conductor 600, the laser calibration component 451b calibrates the areas requiring wrapping, facilitating subsequent manual wrapping operations. After wrapping, the first X-axis drive source 500a drives the wrapping head 450 back to wrap the U-shaped primary conductor 600 until the required thickness is achieved. Finally, the diameter sensors 425 of the horizontal diameter measuring module 420a and the vertical diameter measuring module 420b check whether cable paper is detected at their respective locations. If cable paper is detected, the wrapping thickness is the required thickness, indicating a qualified product, which is then unloaded by a crane.

[0147] When working with U-shaped primary conductors 600 of different lengths, select several support components 300 near the end, allowing the other support components 300 near the lifting platform 200 to descend, thus opening the support rod 340 outwards. The second X-axis drive source 500b drives the lifting platform 200 towards the support components 300, shortening the distance between the lifting platform 200 and the support components 300, thereby supporting the shorter U-shaped primary conductor 600. The height of the support platform 200 and the support components 300 can also be adjusted to accommodate wrapping operations of U-shaped primary conductors 600 of different sizes.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention.
