Description

Technical Field

[0001] This invention relates to the field of stator coil production for large hydropower station generators, and in particular to a winding system for generator stator coil production lines. Background Technology

[0002] Driven by energy structure transformation and the "dual-carbon" strategy, the installed capacity of hydropower stations continues to expand. For hydropower stations, the performance of the generator directly determines the power generation efficiency, stability, and service life of the unit. As the "heart" of the large generator, the stator coil's manufacturing process is a key factor affecting the overall quality of the generator. The production process of the stator coil for hydropower generators mainly includes material preparation, transposition braiding (braiding results in rectangular rods composed of two rows of flat copper sheets (i.e., electromagnetic wires)), insulation padding, straightening and curing, chamfering and removal of release tape, short-circuit testing, and end forming. Among these, insulation padding is one of the core processes in stator coil production. This process involves placing insulation pads on the two narrow sides of the braided rectangular rod, then winding release tape around it, and finally wrapping the release tape around both ends of the rod to fix it. The release tape serves as an isolation medium during rod forming, ensuring tight and uniform winding onto the rod surface while also ensuring smooth detachment after curing and avoiding damage to the coil surface caused by winding. Currently, the stator coils of domestic hydropower generator units are mostly produced manually. This involves manually placing insulating pads on both sides of the coil bar and then manually winding the release tape. This process is difficult and labor-intensive. Manual winding makes it hard to maintain consistent winding force; excessive force can cause stretching, deformation, and breakage of the release tape, while insufficient force can result in loose adhesion, air bubbles, and wrinkles, potentially leading to surface defects during subsequent coil molding. Furthermore, manual winding makes it difficult to ensure consistent winding angles. Angle deviations can cause uneven overlap of the release tape, resulting in missed or over-wound areas, sometimes requiring rework. This not only wastes raw materials but also significantly extends the production cycle and reduces efficiency. Therefore, designing a production line that automatically feeds insulating pads and automatically winds the release tape is crucial for the intelligent production of stator coils for large hydropower generators. Summary of the Invention

[0003] In view of this, the present invention proposes a winding system for a generator stator coil production line.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The winding system for a generator stator coil production line of the present invention includes an insulating pad feeding machine and a winding machine connected together. The insulating pad feeding machine includes a first frame with a first protective shell and an insulating pad cutting mechanism, an insulating pad storage and feeding mechanism, an insulating pad gripping device and a wire bar support mechanism arranged sequentially from bottom to top in the first frame. The insulating pad gripping device grips the insulating pads from the insulating pad storage and feeding mechanism and places them on the narrow sides of the wire bar, and then feeds the wire bar into the winding machine. The wrapping machine includes a second frame and a release tape winding mechanism, a tape winding mechanism, and a conveying mechanism sequentially arranged on the second frame. It also includes a release tape cutting mechanism for cutting the release tape and a tape cutting mechanism for cutting the tape. The second frame has an installation platform. The first support of the release tape winding mechanism extends upward from the installation platform. The tape winding mechanism, the release tape cutting mechanism, and the tape cutting mechanism are all arranged on the installation platform. The conveying mechanism is located behind the tape winding mechanism.

[0005] The beneficial effects are: This invention utilizes an insulating mat feeding machine to achieve automatic feeding of insulating mats, and a wrapping machine to achieve automatic wrapping of the release tape and fixing with adhesive tape, thereby realizing automatic insulating mat wrapping of the wire rod. Specific advantages are as follows: In actual production, the length of the braided wire rod (composed of multiple insulating copper sheets) is often quite long. Each side of the wire rod typically requires the placement of multiple insulating pads. During the feeding process, the last two pads on the wire rod (located on one side of the wire rod) may be too long. An insulating pad cutting mechanism is used to remove the excess portion. This invention features a pair of insulating pad storage and feeding mechanisms installed within the first frame. These mechanisms can push the insulating pads from the tray to the picking position, enabling simultaneous gripping of two insulating pads. Once the insulating pads are in place, the insulating pad gripping device can push the wire rod (the part with the insulating pad on the outside) a certain length towards the wrapping machine. The process is then repeated, allowing for continuous placement of insulating pads on both sides of the wire rod, thus improving work efficiency.

[0006] This invention utilizes a release tape winding mechanism for automatic winding, ensuring not only consistent winding angles but also consistent winding density and force, thereby guaranteeing uniform winding, improving winding efficiency, and ensuring winding quality. After winding, the release tape is automatically cut using a cutting mechanism. A conveying mechanism pulls the wire rod, enabling simultaneous pulling and winding during operation, achieving continuous winding of the release tape and improving winding efficiency. When the wound wire rod passes through the tape winding mechanism, its ends are partially wound using the tape winding mechanism, ensuring efficient fixation of the release tape. Furthermore, the entire winding process only requires worker assistance in pulling the free ends of the release tape and tape onto the wire rod, further improving winding efficiency. Both the release tape winding gear and the tape winding gear are hollow gears, allowing stator coils of different specifications to pass through, thus meeting the high-efficiency winding requirements of stator coils of various sizes, offering a high degree of flexibility.

[0007] Preferably, the insulating mat gripping device includes a first X-axis power mechanism disposed on the top of the first frame, a first Y-axis power mechanism driven by the first X-axis power mechanism to reciprocate in the X direction, and a pair of gripping mechanisms driven by the first Y-axis power mechanism to open and close in the Y direction. The gripping mechanism includes a Z-axis slide module and a gripping seat driven by the Z-axis slide module to rise and fall. The gripping seat is disposed along the X direction, and multiple adsorption elements for adsorbing insulating mats are fixedly connected to the gripping seat. The insulating mat gripping device also includes a pair of wire bar grippers, and each gripping seat is provided with one wire bar gripper. The insulating mat gripping device grips and delivers the wire bar to the wrapping machine through the wire bar grippers.

[0008] The beneficial effects are as follows: This invention features a pair of insulating pad storage and feeding mechanisms installed within the first frame. These mechanisms can push the insulating pads from the tray to the picking position, enabling simultaneous gripping of two insulating pads. Each gripping seat can be adjusted in the X, Y, and Z directions, thus achieving flexible picking and placing of insulating pads, improving feeding efficiency, and laying the foundation for automated production of hydroelectric stator coils. In this invention, once the insulating pads are in place, the insulating pad gripping device can push the coil bar to the next process by a certain length, then reset and repeat the insulating pad gripping and placement operation. This allows for continuous placement of insulating pads on both sides of the coil bar, improving work efficiency.

[0009] Preferably, the insulating pad cutting mechanism includes a second X-axis power mechanism mounted on the base plate of the first frame and a pair of cutting components driven back and forth by the second X-axis power mechanism. Each cutting component includes a mounting component, an insulating pad cutting cylinder mounted on the mounting component, and a first cutter driven back and forth in the Y-axis by the insulating pad cutting cylinder. The first cutter is vertically positioned, and a recycling box is located below the first cutter. The advantages are: in this invention, the insulating pad is placed in the X-axis direction, and the insulating pad cutting cylinder can drive the first cutter to cut in the Y-axis direction, thereby breaking the insulating pad, with the excess falling directly into the recycling box; furthermore, the X-axis positions of the insulating pad cutting cylinder and the first cutter can be flexibly adjusted, thereby achieving cutting at different positions to meet the needs of different lengths of wire bars, increasing flexibility, and thus improving the flexibility of the stator coil production line.

[0010] More preferably, the base plate of the first frame is provided with a pair of first Y-axis seats, and each pair of prime number insulating pad storage and feeding mechanisms is installed on the two first Y-axis seats. The insulating pad storage and feeding mechanism includes a moving beam driven by a drive mechanism to move in the Y direction, an insulating pad feeding pusher fixed to the moving beam, and a material tray located on one side of the insulating pad pusher. The insulating pad feeding pusher is connected to the moving beam through a buffer connection structure, and the buffer connection structure is located at the bottom of the moving beam. The drive mechanism includes a drive motor, an X-axis mounted above the two first Y-axis seats, and a transmission rack disposed above each first Y-axis seat. The drive motor is drively connected to the X-axis, and the two ends of the X-axis are provided with gears that mesh with the transmission racks one by one. The invention includes a transmission gear; each first Y-axis seat is equipped with an upper Y-axis slide rail, and each upper slide rail is slidably equipped with a first slide block. Each first slide block has a fixing block at its top that engages with the end of the transmission rack. The fixing block and one end of the transmission rack are fixedly connected. The left and right ends of the moving beam are respectively fixedly connected to a pair of first slide blocks. The driving mechanism drives the insulating pad feeding pusher to move left or right through the moving beam. The transmission racks of the two driving mechanisms are staggered left and right to avoid each other's transmission gears. The two driving motors operate in opposite directions, causing one of the insulating pad feeding pushers to push an insulating pad in one tray forward, while the other pusher pushes an insulating pad in another tray backward. The beneficial effect is that this invention installs a pair of insulating pad storage and feeding mechanisms on the same layer within the first frame, enabling simultaneous feeding of two insulating pads. Combined with two gripping mechanisms, it can grip two insulating pads each time, achieving simultaneous feeding of insulating pads on both sides of the wire bar.

[0011] Preferably, the insulating mat feeding machine further includes an insulating mat auxiliary clamping mechanism, which is located below the first Y-axis power mechanism. This mechanism includes a second Y-axis power mechanism, a pair of bases driven to open and close by the second Y-axis power mechanism, and insulating mat auxiliary pushers disposed on each base. The bases are all arranged along the X-axis, and at least two lifting cylinders are fixedly connected to each base. The power end of each lifting cylinder is connected to a horizontally arranged pusher fixing seat via a connecting plate. At least two insulating mat auxiliary pushers are disposed on each pusher fixing seat. Each insulating mat auxiliary pusher includes a pusher cylinder and a U-shaped pusher driven by the pusher cylinder. The advantages are: the U-shaped pusher can abut against the narrow side of the wire rod, assisting in clamping the wire rod and insulating mat, preventing the insulating mat from slipping, and meeting the placement requirements of two or more layers of insulating mats on each narrow side of the wire rod; each U-shaped pusher can be adjusted in the X, Y, and Z directions, and can descend and retract to avoid the gripping mechanism when it places the insulating mat.

[0012] Preferably, the first support of the release tape winding mechanism extends upward from the mounting platform and includes a release tape winding motor, a release tape winding gear, and a release tape fixing structure fixed to the release tape winding gear, all mounted on the first support. The release tape winding motor and the release tape winding gear are connected by a toothed first rack belt, and the release tape winding motor drives the release tape winding gear to rotate via the first rack belt. The tape winding mechanism includes a second support fixed to the mounting platform and a belt drive mechanism mounted on the second support. Both the tape winding gear and the release tape winding gear of the belt drive mechanism have a central hole through which the wire bar passes horizontally. A tape fixing member is provided on the tape winding gear of the belt drive mechanism, so that the tape fixing member rotates synchronously with the tape winding gear. The beneficial effects are as follows: This invention utilizes a release tape winding mechanism for automatic winding, ensuring not only consistent winding angles but also consistent winding density and force, thereby guaranteeing uniform winding, improving winding efficiency, and ensuring winding quality. After winding, the release tape is automatically cut using a cutting mechanism. The conveying mechanism of this invention can pull the wire rod, achieving simultaneous pulling and winding, thus realizing continuous winding of the release tape and improving winding efficiency. When the wound wire rod passes through the tape winding mechanism, its ends can be partially wound using the tape winding mechanism, ensuring the release tape's fixing efficiency. Furthermore, the entire winding process only requires worker assistance in pulling the free ends of the release tape and tape onto the wire rod, significantly improving winding efficiency. Both the release tape winding gear and the tape winding gear are hollow gears, allowing stator coils of different specifications to pass through, thus meeting the high-efficiency winding requirements of stator coils of different specifications, exhibiting a high degree of flexibility.

[0013] Preferably, the wrapping machine further includes a lifting mechanism that drives the release tape winding mechanism to rise and fall. The lifting mechanism includes a horizontally arranged base, a pair of supports fixed to the base, and a worm gear screw jack driven by a motor. The connecting plate at the linear output end of the worm gear screw jack is fixed to the first upright. Each support is provided with a vertical first slide rail, and the first upright has a slider that cooperates with each first slide rail. The wrapping machine further includes a second wire bar limiting mechanism disposed between the release tape winding mechanism and the tape winding mechanism. The second wire bar limiting mechanism includes a limiting power source, a mounting frame disposed on the front side of the second upright, a bidirectional screw rotatably disposed on the mounting frame, and a pair of limiting components disposed on the bidirectional screw rotatably. The limiting components include a moving block screwed to the bidirectional screw rotatably and a limiting roller vertically fixed to the moving block. The two limiting rollers are spaced apart to limit the wire bar. The limiting power source is connected to the bidirectional screw rotatably, and drives the two limiting rollers to open and close through the bidirectional screw rotatably.

[0014] The beneficial effects are as follows: The wire rods obtained in the stator coil braiding process are usually composed of multiple flat copper wires arranged together. The wire rods are relatively long and wide. This invention installs a second wire rod limiting mechanism between the demolding belt winding mechanism and the tape winding mechanism, which can limit the wire rods and prevent them from deviating during movement, thus affecting the winding quality. In addition, the distance between the two limiting rollers can be flexibly adjusted to limit wire rods of different widths, thereby meeting the winding requirements of wire rods of different specifications.

[0015] Preferably, the tape cutting mechanism includes a horizontal seat fixed to the rear side of the second upright, the middle part of which extends into the central hole of the second upright, and a mounting shaft is mounted on the horizontal seat located in the central hole. The tape cutting mechanism also includes a cutting gear and a pressing gear spaced apart on the mounting shaft. The tape cutting mechanism further includes a pressing rack driven horizontally by a pressing cylinder and a cutting rack driven horizontally by a tape cutting cylinder. The cutting rack meshes with the cutting gear, and the pressing rack meshes with the pressing gear. A pressing plate for pressing the tape downwards is fixedly connected to the pressing gear. A cutting plate is fixedly connected to the cutting gear, and a toothed second cutter is provided on the cutting plate. The beneficial effect is that the pressing plate and the first cutter are arranged side-by-side, and both the pressing plate and the first cutter can rotate around the mounting shaft, allowing for flexible adjustment of the positions of the pressing plate and the first cutter. When the tape needs to be cut, the top pressure cylinder first drives the top pressure plate through the top pressure rack and top pressure gear, so that the top pressure plate presses the tape above it upward. The first cutting cylinder lifts the cutting plate upward through the cutting rack and cutting gear, thereby realizing the cutting of the tape.

[0016] Preferably, the demolding strip cutting mechanism includes a horizontal cylinder mounted on the second stand and a vertical plate driven by the horizontal cylinder to move horizontally reciprocally. It also includes a demolding strip cutting cylinder and an insulating pad cutting assembly mounted on the vertical plate. The insulating pad cutting assembly is located in front of the tape winding gear and includes an upper pressure block driven to rise and fall by the demolding strip cutting cylinder and a lower cutting blade mounted on the lower part of the vertical plate. The lower cutting blade is horizontally positioned and toothed, and the upper pressure block has pressing grooves corresponding vertically to the lower cutting blade. The advantages are: the lower cutting blade is located on one side of the wire rod; the horizontal cylinder can adjust the horizontal position of the demolding strip cutting cylinder, moving the lower cutting blade below the demolding strip to meet the cutting requirements; the demolding strip cutting cylinder drives the upper pressure block to rise and fall; the upper pressure block has a slotted design, pressing down on the demolding strip during its descent, cooperating with the lower cutting blade to achieve automatic cutting of the demolding strip.

[0017] The conveying mechanism includes a lower conveying unit mounted on the mounting platform, an upper conveying unit mounted above the lower conveying unit, and a lifting power mechanism that drives the upper conveying unit to rise and fall. The lower conveying unit is a horizontally arranged conveying roller unit. The lifting power mechanism includes a portal frame mounted on the mounting platform, a lifting power source fixed to the portal frame, and a vertical mounting base driven to rise and fall by the lifting power source. The vertical mounting base is located above the lower conveying unit. The upper conveying unit is a synchronous belt drive mechanism mounted on the vertical mounting base. The first synchronous belt of the synchronous belt drive mechanism is parallel to the lower conveying unit. Attached Figure Description

[0050] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.

[0051] It should be noted that the braided wire rod is usually composed of multiple flat copper wires arranged in a certain order. Its cross-section is rectangular with four rectangular faces of equal length, one pair of which are narrower. During the insulation padding process, insulation pads (i.e., narrow-sided insulation pads) are placed on the sides of the wire rod. Then, the release tape is wrapped around it, and tape is wrapped around both ends of the wire rod to prevent the release tape from unraveling. Therefore, the insulation pad feeding machine proposed in this invention uses a double-grip method when picking up the insulation pads. It should also be noted that the stator coils of large motors in hydropower stations are usually braided from two rows of electromagnetic wires (i.e., flat copper wires) with alternating positions. The width of the insulation pad is usually consistent with the side width of one row of electromagnetic wires. Therefore, when placing the insulation pads, two insulation pads are usually required on each side of each section of the wire rod.

[0052] Combination Figure 1 It can be seen that the winding system for a generator stator coil production line proposed in this invention includes an insulating pad feeder A and a winding machine B connected together. Combined with... Figures 2-4 It is known that the insulating mat feeding machine includes a first frame A100 with a first protective shell A106, an insulating mat cutting mechanism A200 disposed on the base plate A101 of the first frame A100, two pairs of insulating mat storage and feeding mechanisms A300 disposed above the insulating mat cutting mechanism A200, an insulating mat auxiliary clamping mechanism A400 disposed above the insulating mat storage and feeding mechanism A300, and an insulating mat gripping device A500 (with a pair of gripping mechanisms) disposed above the first frame A100. The first frame A100 has a base plate A101. An insulating mat cutting mechanism A200, an insulating mat storage and feeding mechanism A300, an insulating mat auxiliary clamping mechanism A400, a wire rod support mechanism A700, and an insulating mat gripping device A500 are sequentially arranged from bottom to top on the base plate A101 within the first frame A100. The insulating mat storage and feeding mechanism A300 consists of two pairs (or one or more pairs), arranged vertically on each layer, with one pair installed on each layer. During operation, the two pairs of insulating mat storage and feeding mechanisms A300 can work alternately to ensure continuous gripping by the insulating mat gripping device.

[0053] Combination Figures 3-7 It is known that the insulating mat gripping device A500 includes a first X-axis power mechanism A501 disposed on the top of the first frame A100, a first Y-axis power mechanism A502 driven by the first X-axis power mechanism A501, and a pair of gripping mechanisms A503. The first X-axis power mechanism A501 includes a pair of X-axis bases A501a spaced apart from each other, a first X-axis power source disposed on one of the X-axis bases A501a, and a lead screw A501 rotatably disposed on each X-axis base A501a. d (a linear screw module can be used), each screw A501d is connected to a third Y-axis seat A501e in the Y direction to ensure the linear reciprocating motion of the third Y-axis seat A501e and provide support for it; in addition, the insulating pad auxiliary clamping mechanism A400 has a pair of second Y-axis seats A401b, each X-axis base A501a is mounted on the ends of the two second Y-axis seats A401b through a pair of fourth legs A105, the two X-axis bases A501a are spaced apart, and the two gripping mechanisms are located between the two X-axis bases A501a.

[0054] The first X-axis power source includes a first motor mounted on one of the X-axis bases A501a. Figure 6(Omitted) and a dual-output reducer A501b, including a steering box A501c mounted on another X-axis base A501a. A first motor is connected to reducer A501b. One output end of reducer A501b is connected to steering box A501c via drive shaft A501f. The other output end of reducer A501b and the output end of steering box A501c are respectively connected to a lead screw A501d. Thus, the synchronous rotation of the two lead screws A501d is achieved by a motor + reducer combination, ensuring the synchronous rotation of the two second sliding... The synchronous X-axis movement of the seat also reduces the number of power sources; the first Y-axis power mechanism A502 is set on the third Y-axis seat A501e, which includes two Y-axis linear power sources spaced apart on the third Y-axis seat A501e. Each Y-axis linear power source (which can be an electric cylinder or a slide module with a motor) is equipped with a gripping mechanism A503. The two Y-axis linear power sources can drive the two gripping mechanisms A503 to move simultaneously in opposite directions and towards each other, thereby meeting the requirements of simultaneous gripping of materials at the left and right material handling stations and simultaneous release of materials from the insulating pads on both sides of the bar.

[0055] Combination Figures 5-7 It is known that the two gripping mechanisms A503 have the same structure, both including a Z-axis slide module A503a and a gripping seat A503b driven to rise and fall by the Z-axis slide module A503a (with a servo motor). Both gripping seats A503b are arranged along the X-axis. Each gripping seat A503b has multiple suction components A503c (preferably vacuum suction cups) fixed to its side, which can suction the sides of the insulating pad, facilitating the gripping and placement of the insulating pad. To ensure simultaneous material handling by the two gripping mechanisms A503, the feeding positions of the insulating pad storage and feeding mechanism A300 below are located on the left and right sides of the first frame A100. Therefore, during gripping, the two gripping mechanisms A503 are located at the two ends of the third Y-axis seat A501e, and then descend to grip the insulating pad below. The specific working process is as follows: Adjust the X and Y positions of the two gripping mechanisms A503 so that they correspond vertically to the feeding positions of each pair of insulating pad storage and feeding mechanisms A300. Activate the Z-axis sliding module A503a to move the gripping seat A503b downwards. The gripping seat A503b then picks up the insulating pads from the side, ensuring simultaneous gripping of both insulating pads. After gripping, the two gripping seats A503b rise simultaneously. The first X-axis power mechanism A501 moves the X-axis position of the two insulating pads, and the two Y-axis linear power sources move the insulating pads in the Y-axis direction, placing the insulating pads on each side of the wire rod.

[0056] Combination Figures 5-7It is known that each gripping seat A503b is equipped with a wire bar gripper, which includes a gripping cylinder A504a (horizontally installed) mounted on the gripping seat A503b. Each gripping cylinder A504a is fixedly connected to a wire bar clamping plate A504b, with two wire bar clamping plates A504b arranged correspondingly and vertically. Due to the excessive length of the wire bar, this invention can attach insulating pads of the same length to both sides of the wire bar each time. After each pad is attached, the wire bar is pulled outward by a section. When pulling outward, the two gripping cylinders A504a drive the wire bar clamping plates A504b to close simultaneously, clamping the wire bar and the insulating pad. After successful gripping, the insulating pad gripping device A500 adjusts the two gripping mechanisms to move synchronously to the right, so that the wire bar (with the insulating pad on the outside) moves a certain length to the right and enters the wrapping machine.

[0057] In actual production, the length of the braided wire rod (composed of multiple insulating copper sheets) is often quite long. Each side of the wire rod typically requires multiple insulating pads along its length. During the feeding process, the total length of the insulating pads may exceed the length of the wire rod, thus necessitating the cutting of the insulating pads corresponding to each wire rod. To address this, the present invention installs two symmetrically arranged insulating pad cutting mechanisms A200 on the base plate A101 of the first frame A100. Combined with... Figure 2 , 8 As shown in Figure -9, the insulating mat cutting mechanism includes a second X-axis power mechanism A201 mounted on the base plate A101 and a pair of first cutting components A202 driven reciprocating by the second X-axis power mechanism A201. The second X-axis power mechanism A201 has a horizontally reciprocating movable seat A201a in the X-axis direction (the length direction of the movable seat A201a is the Y-axis, providing sufficient installation space). The first cutting components A202 are symmetrically arranged at both ends of the movable seat A201a. The first cutting components A202 include components fixed to... The moving base A201a has a horizontal mounting plate A202a at its end, an insulating pad cutting cylinder A202b mounted on the horizontal mounting plate A202a, and a first cutter A202c driven by the insulating pad cutting cylinder A202b to reciprocate in the Y direction. The first cutter A202c is vertically arranged. On the base plate A101 located on the left and right sides of the X-direction power mechanism, there are recycling boxes A203 that cooperate with each first cutter A202c. Excess insulating pads cut off can fall directly into the recycling box A203 for centralized recycling.

[0058] Combination Figure 8It is known that the horizontal mounting plate A202a is mounted on the upper outer side of the movable seat A201a, providing a certain cutting stroke and cutting space for the first cutter A202c. When not cutting, the first cutter A202c is hidden under the material tray A303. When cutting, the insulating pad cutting cylinder A202b works to make the first cutter A202c extend to the outside of the material tray A303 (the extension directions of the two insulating pad cutting mechanisms A200 are opposite). When cutting is required, the insulating pad gripping device A500 moves the two insulating pads from the feeding side of the material tray A303 and suspends the insulating pads above the recycling box A203. When the piston rod of the insulating pad cutting cylinder A202b extends outward, the first cutter A202c passes under the insulating pad and cuts it. The excess insulating pad falls into the recycling box A203 below.

[0059] The second X-axis power mechanism A201 of the present invention includes a Y-axis electric cylinder A201b disposed in the middle of the base plate A101 and a pair of X-axis slide rails A201c disposed on both sides of the Y-axis electric cylinder A201b. Each X-axis slide rail A201c is provided with a third slide block, and the left and right ends of the movable seat A201a are respectively fixedly connected to the third slide block. To ensure the installation height of the first cutter A202c, the movable seat A201a is located above the third slide block. The movable seat A201a of the present invention moves back and forth in the X-axis along the X-axis slide rail A201c through the third slide block, thereby realizing the flexible adjustment of the first cutter A202c in the X-axis, realizing the flexible cutting of the insulating pad, and meeting the needs of wire bars of different lengths.

[0060] Combination Figure 3 It can be seen that two sets of first support legs A102 are provided at the left and right ends of the base plate A101. Each set of first support legs A102 is fixedly connected to a first Y-axis seat A308 in the Y direction, providing an installation foundation for the two insulating pad storage and loading mechanisms A300 on the same layer. Combined with... Figures 10-13It is understood that the insulating mat storage and feeding mechanism A300 includes a drive mechanism A304 mounted on a first Y-axis seat A308, a moving beam A301 driven by the drive mechanism A304 to move in the Y direction, an insulating mat feeding pusher A302 mounted on the moving beam A301, and a material tray A303 located between the two first Y-axis seats A308. The drive mechanism A304 can drive the moving beam A301 to reciprocate in the Y direction, allowing the insulating mat pusher to move in the Y direction. During operation, the two drive mechanisms A304 operate in opposite directions, causing one insulating mat feeding pusher A302 to push the insulating mat to the left, while the other insulating mat feeding pusher A302 pushes the insulating mat in the other material tray A303 to the right, allowing the insulating mats to be easily grasped from the left and right sides of the first frame A100. In actual production, since insulating pads need to be placed on both sides of the wire rod, the present invention installs a pair of insulating pad storage and feeding mechanisms A300 in each layer, which can realize the simultaneous feeding of insulating pads in the two material trays A303, so that the insulating pad gripping device A500 can grip two insulating pads at the same time and place them on both sides of the wire rod, thereby improving the feeding efficiency of insulating pads and thus improving the gluing efficiency of the wire rod.

[0061] Combination Figure 10 It can be seen that each first Y-direction seat A308 is provided with a Y-direction downward sliding rail A309, and a material tray slide is slidably arranged on each downward sliding rail A309. The two ends of the material tray A303 are bolted to the material tray slide (for easy disassembly). The material tray slide can move along the downward sliding rail A309, making it convenient to replace the material tray. After replacement, the new material tray can be fixed on the material tray slide. By fastening the material tray slide to the first Y-direction seat A308, the material tray A303 is fixed and prevented from moving due to the force on the insulating pad during material feeding.

[0062] Combination Figures 10-13It can be seen that the drive mechanism A304 includes a drive motor A304a (set on the first Y-axis seat A308 on the left), an X-axis shaft A304b mounted above the two first Y-axis seats A308, and a transmission rack A304d set above the first Y-axis seats A308. The drive motor A304a and the X-axis shaft A304b are connected by a coupling. Both ends of the X-axis shaft A304b are provided with transmission gears that mesh with the transmission rack A304d one by one. Each first Y-axis seat A308 is provided with a support frame A304c for supporting the X-axis shaft A304b. The X-axis shaft A304b and the support frame A304c are rotatably engaged. The two transmission gears are respectively located in their corresponding support frames A304. Inside the support frame A304c, the transmission rack A304d is parallel to the first Y-direction seat A308 and extends out from the support frame A304c; each first Y-direction seat A308 is provided with an upper slide rail A310 in the Y direction, and each upper slide rail A310 is slidably provided with a first slide block A304f. Each first slide block A304f has a fixing block A304e at its top that engages with the end of the transmission rack A304d. The fixing block A304e is fixedly connected to one end of the transmission rack A304d, and the other end of the transmission rack A304d meshes with the transmission gear inside the support frame A304c to ensure reliable movement of the transmission rack A304d; the left and right ends of the moving beam A301 are respectively fixedly connected to the first slide block A304f. During operation, the drive motor A304a transmits torque to two transmission gears via the X-axis A304b, causing the two Y-axis racks to move synchronously in the Y direction. During this process, the transmission rack A304d transmits power to the first slide A304f, causing the two first slides A304f to move synchronously in the Y direction, thereby driving the translation of the moving beam A301. The moving beam A301 then moves the insulating pad feeding pusher A302.

[0063] In actual installation, the drive motors A304a of the two drive mechanisms A304 are spaced apart, and the transmission racks A304d of the two drive mechanisms A304 are staggered left and right to avoid each other's transmission gears. During material handling, the insulation mat feeding stations are located at the left and right ends of the first frame A100. Therefore, during actual feeding, the two drive motors A304a rotate in opposite directions, causing the two insulation mat feeding pushers A302 of each layer to push the insulation mats towards the feeding side. Furthermore, the insulation mat storage and feeding mechanisms are installed in a one-to-one correspondence, and the upper and lower insulation mat storage and feeding mechanisms are connected by a second support leg A103.

[0064] Combination Figures 12-13 It can be seen that each insulating pad feeding pusher A302 is connected to the moving beam A301 through multiple spaced buffer connection structures. These buffer connection structures are located at the bottom of the moving beam A301, allowing for both floating adjustment of the insulating pad feeding pusher A302 and facilitating its resetting. Combined with... Figure 13It can be seen that the buffer connection structure A305 includes a second slider A305a fixedly connected to the bottom of the moving beam A301 and a second slide block A305b slidably disposed on the second slider A305a. The second slide block A305b has a T-shaped structure and is fixedly connected to the insulating pad feeding pusher A302. The buffer connection structure also includes a pair of fixing blocks A305c fixedly connected to the bottom of the moving beam A301. A buffer spring A305d is disposed between each fixing block A305c and the second slide block A305b. The insulating pad feeding pusher A302 is a push rod disposed in the X direction. The height of the push rod is lower than the height of the moving beam A301. Multiple protective push blocks A302a acting on the insulating pad are disposed at intervals on the working surface of the insulating pad feeding pusher A302.

[0065] During operation, the moving beam A301 drives the insulating pad feeding pusher A302 via the fixed block A305c, pushing the insulating pad towards the feeding side. During this process, the buffer spring A305d between the fixed block A305c and the insulating pad feeding pusher A302 is under pressure. When the material tray A303 is empty, the drive motor A304a rotates in the reverse direction, causing the moving beam A301 to move in the reverse direction, and the insulating pad feeding pusher A302 quickly resets, facilitating tray replacement. When the moving beam A301 moves towards the feeding station, it acts on multiple second slides via multiple buffer springs A305d, causing the insulating pad feeding pusher A302 to move towards the feeding station, enabling floating adjustment of the insulating pad feeding pusher A302. During the return stroke, the external force acting on the buffer springs A305d disappears, causing the insulating pad feeding pusher A302 to quickly reset.

[0066] Combination Figure 10 and Figure 11 It is known that an X-oriented mounting beam A306 is erected above the feeding side of the material tray A303. Multiple insulating pad pressing mechanisms A307 are spaced apart on the mounting beam A306. Each insulating pad pressing mechanism A307 includes a vertically arranged pressing cylinder A307a and a pressing pusher A307b driven by the pressing cylinder A307a. Multiple pressing pushers A307b act simultaneously on the top of the insulating pad on the picking side. When picking up the material, the insulating pad can be pressed to ensure that the insulating pad is fed one by one and to avoid the insulating pad sticking together when picking up the material.

[0067] Combination Figure 3 It can be seen that the insulating mat auxiliary clamping mechanism A400 is positioned above the insulating mat storage and feeding mechanism A300. Combined with... Figures 14-15It is known that the insulating pad auxiliary clamping mechanism A400 includes a second Y-axis power mechanism A401, a pair of bases A402 driven to open and close by the second Y-axis power mechanism A401, and an insulating pad auxiliary pusher A403 disposed on each base A402; the second Y-axis power mechanism A401 includes a pusher motor A401a, a pair of second Y-axis seats A401b (each second Y-axis seat A401b is mounted on its corresponding first Y-axis seat A308 via a third support leg A104), and a synchronous belt drive pair A401c disposed at the bottom of each second Y-axis seat A401b. The pusher motor A401a is disposed on one of the second Y-axis seats A401b and has a connecting shaft A401d disposed in the X direction. In actual installation, each base has a synchronous belt drive pair on each side, and all four synchronous belt drive pairs A401c are connected to the connecting shaft A401d, as detailed in [see details]. Figure 17 When the push motor 401a is driven by the shaft A401d, it drives four synchronous belts to work synchronously. The upper layers of the four synchronous belts are aligned, and the lower layers are aligned as well. In actual installation, one base A402 is connected to the lower layer of a pair of synchronous belt drives, and the other base A402 is connected to the upper layer of another pair of synchronous belt drives, ensuring that the two bases can open and close in the Y direction (see the closed diagram). Figure 18 Middle A, open like Figure 18 As shown in Figure B), the U-shaped pusher is used to assist in clamping and opening, avoiding the gripping seat and meeting the feeding requirements of two insulating pads on each side of the bar within the same length range.

[0068] Combination Figures 14-16 It can be seen that the base A402 is arranged along the X direction, and two lifting cylinders A404 (with their piston rods located below) are fixedly connected to each base A402. The lifting cylinders A404 are connected to horizontally arranged pusher fixing seats A405 through connecting plates A406. Each pusher fixing seat A405 is provided with three insulating pad auxiliary pushers A403. Each insulating pad auxiliary pusher A403 includes a pusher cylinder A403a and a U-shaped pusher A403b driven by the pusher cylinder A403a. The insulating pad auxiliary pusher A403 is located on one side of the bar and can assist in clamping the bar. When the pusher cylinder extends, the U-shaped pusher A403b assists in supporting the insulating pad on one side of the bar, preventing the insulating pad from falling off. Each U-shaped pusher A403b can be adjusted in the X, Y, and Z directions. When the gripping mechanism places the insulating pad, it can descend and retreat to avoid the gripping mechanism, making it easier to place the insulating pad. When the insulating pad is in place, the U-shaped pusher A403b can rise forward and reset to rest on the insulating pad, making it easier for the insulating pad gripping device A500 to grip the insulating pad again, which is beneficial for the feeding of double-layer insulating pads.

[0069] Combination Figure 2 and Figure 14It can be seen that the bar support mechanism A700 of the present invention (connected to the conveyor roller conveyor of the stator coil production line) is a roller conveyor support. Combined with... Figure 23 It can be seen that the left end of the frame A701 of the bar support mechanism A700 is mounted on the first Y-axis seat A308 below, and the right side of the frame A701 is fixedly connected to the second Y-axis seat A401b below. Multiple conveying rollers A703 (connected by chains) are provided on the frame to provide rigid support for the bar. The insulating pad auxiliary pusher A403 is located between the conveying rollers A703 of the bar support mechanism A700, providing working space for the insulating pad auxiliary pusher A403. The inlet of the bar support mechanism A700 has a trumpet-shaped feed channel A702, and the outlet is equipped with a first bar limiting mechanism. The first wire rod limiting mechanism includes a first limiting cylinder and a pair of second limiting cylinders A601. The first limiting cylinder has a mounting plate (vertically arranged, with a limiting plate A603 on its piston rod to prevent the wire rod from moving to the next station) and a pair of second limiting cylinders A601 (horizontally arranged, with a limiting rod connected to its piston rod). The two second limiting cylinders A601 are arranged opposite each other on the second Y-axis seat to limit the two sides of the wire rod. The mounting plate A602 of the first limiting cylinder is fixed in the middle of the second Y-axis seat A401b, and the limiting plate A603 (vertically arranged) is connected to the piston rod of the first limiting cylinder. During operation, the bar support mechanism A700 provides power to the bar. The braided bar enters through the feed channel A702, and the bar support mechanism A700 drives the bar to move to the right. The limiting plate A603 of the first limiting cylinder is in an upward extended state, limiting the bar. When the bar moves into position, the limiting rod of the second limiting cylinder A601 extends, limiting the side of the bar, thus fixing the end of the bar. When conveying outward, the first limiting cylinder drives the limiting plate A603 to descend, and the second limiting cylinder A601 drives the limiting rod to retract, causing the bar to move outward a certain length. Then, the second limiting cylinder A601 is activated again to extend its limiting rod, limiting the side of the bar.

[0070] Combination Figure 19-22 It is known that the wrapping machine B includes a second frame B100 and a release tape winding mechanism B200, a tape winding mechanism B300, and a conveying mechanism B400 sequentially arranged on the second frame B100. It also includes a release tape cutting mechanism 500 and a tape cutting mechanism B600 for cutting tape arranged on the left and right sides of the tape winding mechanism B300. The second frame B100 has a mounting platform B101. The tape winding mechanism B300, the release tape cutting mechanism 500, and the tape cutting mechanism B600 are all arranged on the mounting platform B101. A frame is installed on the mounting platform B101, and a second protective shell B102 is fixedly installed on the frame to protect each mechanism.

[0071] Combination Figure 20-25 It is understood that the demolding tape winding mechanism B200 includes a first stand B201, a demolding tape winding motor B202, a demolding tape winding gear B203 (rotatably mounted on the first stand B201 via a bearing seat, with a central hole in the middle for the wire rod to pass through), and a demolding tape fixing structure B204 (preferably two, one for backup) fixed to the demolding tape winding gear B203; the first stand B201 extends upward through the mounting platform B101, the demolding tape winding motor B202 is mounted on the first stand B201 located below the mounting platform B101, and the demolding tape winding gear B203 is mounted on the first stand B201 located above the mounting platform B101. A drive wheel is mounted on the motor shaft of the demolding tape winding motor B202, and a first rack belt B205 is wound around the drive wheel and the demolding tape winding gear B203. The demolding tape winding gear B203 is a large gear, and the drive wheel is a small gear, realizing speed reduction transmission and meeting the demolding tape winding requirements. During operation, the release belt winding motor B202 drives the release belt winding gear B203 to rotate at a reduced speed via the first rack belt B205. During this process, the release belt fixing structure B204 rotates synchronously around the center of the release belt winding gear B203, thereby realizing the automatic winding of the release belt through the wire bar passing through the center of the release belt winding gear B203. This not only ensures the consistency of the release belt winding angle, but also the consistency of the winding density and the force, thus ensuring the uniform winding of the release belt, improving winding efficiency, and ensuring winding quality.

[0072] In actual production, the flat copper wires of hydroelectric stator coils are usually of different specifications, resulting in slight differences in the center height of the stator coils (the center height difference is on the order of millimeters). To address this, the present invention installs a lifting mechanism B700 below the demolding belt winding mechanism B200, which can finely adjust the center height of the demolding belt winding gear B203, thereby meeting the winding requirements of stator coils of different specifications.

[0073] Combination Figure 24-25It is known that the demolding belt fixing structure B204 includes an upper connecting rod B204a and a lower connecting rod B204b fixedly connected to the demolding belt winding gear B203, and also includes a third support B204c disposed between the upper connecting rod B204a and the lower connecting rod B204b; wherein, the upper connecting rod B204a and the lower connecting rod B204b are both L-shaped structures, so that the third support B204c is located behind the first support B201, thereby wrapping the wire rod coming out of the demolding belt winding gear; the third support The seat B204c is installed between the upper connecting rod B204a and the lower connecting rod B204b. The upper part of the third seat B204c is bolted to the upper connecting rod B204a (or alternatively). The third seat B204c is bolted to the lower connecting rod B204b, making the third seat B204c detachable. This allows for adjustment of the relative position of the third seat B204c. When the position of the third seat B204c changes, the position of the tape roll can be changed, thereby adjusting the winding angle.

[0074] To facilitate adjustment, this invention features angle markers (with angle scale lines and angle information) on the upper connecting rod B204a. Each stator coil specification corresponds to one angle. When the coil specification changes, the angle markers allow for quick adjustment and fixation of the third support B204c. A fixed shaft B204f is located in the middle of the third support B204c. A pair of limiting plates B204d are mounted on the fixed shaft B204f to limit the release strip roll. An anti-detachment block B204e is located at the end of the fixed shaft B204f, connected to the fixed shaft by a pin for easy disassembly and replacement of the release strip roll. In actual installation, the anti-detachment block B204e and the fixed shaft are connected by a pin for easy replacement of the release strip roll. The distance between the two limiting plates B204d is greater than the width of the coil, ensuring that the release strip roll can be released under tension during winding, meeting the automatic wrapping requirements of the release strip on the coil.

[0075] Combination Figure 23-24It is known that the lifting mechanism B700 includes a horizontally arranged base B701, a pair of supports B702 fixedly connected to the base B701, and a worm gear screw jack B704 driven by a motor B703. The motor is a servo motor, which is connected to the input end of the worm gear screw jack B704. The worm gear screw jack B704 (a worm gear screw jack B704 with a nut as the output end can be selected) has a linear output end that can be raised and lowered. A connecting plate B705 is fixedly connected to the linear output end, and the connecting plate B705 is fixedly connected to the first upright B201. To ensure the reliable installation and stable lifting of the demolding belt winding mechanism B200, each support B702 is provided with a vertical first slide rail B706, and two rows of sliders are correspondingly provided on the first upright B201. Each row of sliders slides in cooperation with one first slide rail B706, thereby ensuring a reliable connection between the first upright B201 and the supports B702. During operation, the present invention drives the demolding tape winding mechanism B200 to rise and fall as a whole through the motor and worm gear screw jack B704 (lifting and lowering only require changing the direction of motor rotation), which can realize the fine adjustment of the demolding tape winding mechanism B200, meet the winding requirements of stator coils of different specifications, and improve the degree of flexibility.

[0076] Combination Figure 20 and Figure 22 , Figure 26-27It can be seen that the tape winding mechanism B300 includes a second support B301 fixed to the mounting platform B101 and a belt drive mechanism mounted on the second support B301. The belt drive mechanism has a reduction ratio and includes a tape winding motor B305 mounted on the rear side of the second support B301, a drive gear mounted on the front side of the second support B301, and a tape winding gear B302 mounted at the center of the second support B301. A second rack belt is wound between the drive gear and the tape winding gear B302. The drive gear is a small gear and the tape winding gear B302 is a large gear. The two have a reduction ratio to meet the tape winding requirements. Corresponding to the drive gear A protective plate B306 is provided on the second support B301 to protect the drive gear and the second rack belt. To ensure smooth passage of the wire bar, the tape winding gear B302 is preferably a ring gear. The center hole of the second support B301 has four circumferentially distributed support bearings B303. The inner ring of the tape winding gear B302 rolls with the support bearings B303, and the support bearings B303 support the tape winding gear B302. A tape fixing member B304 (i.e., tape mounting shaft B602) is provided on the front side of the tape winding gear B302. The end of the tape mounting shaft B602 is connected to the anti-detachment plate by a pin. During operation, when the wire rod carrying the release tape passes by, the tape winding motor B305 drives the tape winding gear B302 to rotate, and the tape mounting shaft B602 rotates around the center of the tape winding gear B302, thereby realizing the automatic winding of the tape. After winding a certain length, the tape is cut by the tape cutting mechanism B600. Similarly, the tail end of the wire rod can be wrapped and cut to ensure the wrapping and fixing effect of the release tape on the wire rod.

[0077] Combination Figure 27 It is understood that the wrapping machine also includes a second wire bar limiting mechanism B800 disposed between the demolding belt winding mechanism B200 and the tape winding mechanism B300. The second wire bar limiting mechanism B800 includes a limiting power source, a mounting bracket B801 disposed on the front side of the second stand B301, a bidirectional lead screw B802 rotatably disposed on the mounting bracket B801, and a pair of limiting components disposed on the bidirectional lead screw B802. The limiting components include a moving block screwed to the bidirectional lead screw B802 and a limiting roller B803 vertically fixed to the moving block. The two limiting rollers B803 are spaced apart to limit the wire bars. The limiting power source is connected to the bidirectional lead screw B802 for transmission, and the two limiting components are symmetrically disposed on the bidirectional lead screw B802. The limiting power source can transmit power to the bidirectional lead screw B802, causing the bidirectional lead screw B802 to rotate, thereby realizing the opening and closing of the two limiting components to meet the limiting requirements of wire bars of different widths.

[0078] During actual installation, the mounting platform between the mounting brackets B801 has a horizontal slide rail B804, and the bottom of each moving block is equipped with a slider that cooperates with the horizontal slide rail B804, thereby ensuring the linear reciprocating motion of each moving block.

[0079] Combination Figure 20 and Figure 27 It is known that the limiting power source includes a limiting motor B805 (fixed to the mounting platform B101 via a motor mount) and a synchronous belt drive pair B806 driven by the limiting motor B805. The driven pulley of the synchronous belt drive pair B806 is installed at one end of the bidirectional lead screw B802, thereby realizing the transmission of power. The second synchronous belt of the synchronous belt drive pair B806 is installed in the direction of the lead screw's movement, and the bidirectional lead screw B802 and the first synchronous belt B402b are arranged at an upward 90-degree angle to achieve power transmission within a confined space.

[0080] The working process of the second wire bar limiting mechanism B800 of the present invention is as follows: When the wire bar has not arrived, the two limiting rollers B803 are in an open state. When the front end of the wire bar moves to this position, the limiting motor B805 drives the synchronous belt transmission pair B806 to rotate, thereby transmitting power to the bidirectional lead screw B802 to rotate. The bidirectional lead screw B802 drives the two limiting rollers B803 to move towards each other, thereby limiting the wire bar. Since the upper part of the limiting roller B803 can roll, the friction between it and the wire bar can be reduced, ensuring the smooth passage of the wire bar.

[0081] Combination Figure 26-28It is known that the second support B301 has L-shaped mounting openings on both the left and right sides, providing installation space for the demolding strip cutting mechanism 500 (two of which are symmetrically installed). The demolding strip cutting mechanism 500 includes a horizontal cylinder 501 (either a horizontally mounted guide cylinder or a dual-axis cylinder) mounted on the second support B301, a vertical plate 502 driven by the horizontal cylinder 501 to move horizontally reciprocally, a demolding strip cutting cylinder 503 mounted on the vertical plate 502, and an insulating pad cutting assembly 504. The cylinder body of the horizontal cylinder 501 is fixed at the mounting opening of the second support B301 by a fixed seat 505 (the fixed seat 505 is fixedly installed on the rear side of the second support B301). The piston rod of the horizontal cylinder 501 is located on the front side of the second support B301, which can push the demolding strip cutting cylinder 503 and the insulating pad cutting assembly 504 forward to approach the demolding strip fixing structure B204, so that the demolding strip can be cut after the wrapping is completed. Cutting; the upright plate 502 includes a first mounting part arranged vertically and a second mounting part perpendicular to the first mounting part. The demolding strip cutting cylinder 503 (using a guide cylinder or a dual-shaft cylinder) is vertically mounted on the upper part of the first mounting part. The second mounting part is fixedly connected to the piston rod of the horizontal cylinder 501. The upright plate 502 brings the demolding strip cutting cylinder 503 close to the wire bar to ensure the cutting of the demolding strip on the wire bar. The insulating pad cutting assembly 504 is located in front of the tape winding gear B302. The insulating pad cutting assembly 504 includes an upper pressure block 504a driven to rise and fall by the demolding strip cutting cylinder 503 and a lower cutter 504b arranged at the lower part of the upright plate 502. The lower cutter 504b is arranged horizontally and has teeth. The upper pressure block 504a has a pressing groove corresponding to the lower cutter 504b. During actual installation, the lower cutter 504b is located on one side of the wire rod. The horizontal cylinder 501 can adjust the horizontal position of the demolding strip cutting cylinder 503. The demolding strip cutting cylinder 503 drives the upper pressure block 504a to rise and fall. The upper pressure block 504a has a slotted design. During its descent, it will press down on the demolding strip. It works in conjunction with the lower cutter 504b to achieve automatic cutting of the demolding strip.

[0082] Combination Figure 26-28It is understood that the insulating pad cutting assembly 504 also includes a buffer structure corresponding to the upper pressure block 504a. The buffer structure includes a fixed block 504c horizontally fixed to the vertical plate 502 and a buffer block 504d set on the fixed block 504c. A buffer spring is provided between the buffer block 504d and the fixed block 504c. The lower cutter 504b is fixed to the inner side of the fixed block 504c, and the serrations at its top are higher than those of the fixed block 504c. During cutting, the upper pressure block 504a first acts on the buffer block 504d, which has a certain buffering effect to avoid hard contact between the two. When the upper pressure block 504a continues to descend, it presses down on the buffer block 504d, causing the buffer block 504d to descend. The pressing groove of the upper pressure block 504a is engaged with the lower cutter 504b, thereby cutting the demolding strip. When the demolding strip cutting cylinder 503 resets, the buffer block 504d automatically resets under the action of the buffer spring, waiting for the next cut.

[0083] Combination Figure 26-30 It is known that the tape cutting mechanism B600 includes a horizontal seat B601 fixed to the rear side of the second upright B301. The middle part of the horizontal seat B601 is located in the central hole of the second upright B301, and the middle part of the horizontal seat B601 has a horizontally arranged mounting shaft B602. The tape cutting mechanism B600 also includes a tape pressing structure and a tape cutting structure. The tape pressing structure includes a pressing gear B603a, a pressing plate B603b, a pressing cylinder B603c, and a pressing rack B603d driven linearly by the pressing cylinder B603c on the mounting shaft B602. The pressing rack B603d meshes with the pressing gear B603a. The tape cutting structure includes a horizontally arranged mounting shaft B602. The device consists of a cutting gear B604a, a cutting plate B604b, a tape cutting cylinder B604c, and a cutting rack B604d driven by the tape cutting cylinder. The cutting rack B604d meshes with the cutting gear B604a. The mounting shaft B602 is located inside the center hole of the second stand B601 and is lower than the center of the center hole. The top pressure gear B603a and the cutting gear B604a are rotatably mounted on the mounting shaft B602 through bearings. The top pressure gear B603a is fixedly connected to the top pressure plate B603b (the top pressure plate is provided with a top pressure sponge). The two sides of the cutting gear B604a are connected to the cutting plate B604b, and the first cutter B604e is mounted on the cutting plate B604b. The height of the horizontal seat B601 is lower than the center of the central hole of the second vertical seat B301. The middle part of the horizontal seat B601 has a horizontally extending mounting part, and the top-pressure cylinder B603c and the tape cutting cylinder B604c are fixedly connected to the horizontal mounting part. The bottom of the central hole of the second vertical seat B301 is provided with brackets B605 with horizontal support parts at intervals. The cutting rack B604d and the top-pressure rack B603d are respectively located on their corresponding brackets B605 (the racks and the horizontal support parts of the brackets B605 are slidably engaged by a slide rail slider pair). The piston rod of the top-pressure cylinder B603c is connected to the end of the top-pressure rack B603d, and the piston rod of the tape cutting cylinder B604c is connected to one end of the cutting rack B604d. The top-pressure rack B603d and the cutting rack B604d are both arranged along the length direction of the wire bar. When the piston rods of the top-pressure cylinder B603c and the tape-cutting cylinder B604c extend or retract, they drive the corresponding racks to move back and forth on the bracket B605, thereby causing the cutting gear B604a and the top-pressure gear B603a to rotate around the mounting shaft B602. During the rotation, the cutting plate B604b and the top-pressure plate B603b can rotate synchronously, realizing the independent adjustment of the top-pressure plate B603b and the cutting plate B604b. During the tape conveying process, they can avoid the tape, and during cutting, they can be lifted up one after the other, thus realizing automatic tape cutting.

[0084] To ensure the effective top-pressure adhesion during the initial wrapping of the tape, the tape top-pressure structure of this invention is arranged in two sets at intervals, and top-pressure sponges are installed on both top-pressure plates B603b (which can reduce the impact on the release strip and ensure the integrity of the release strip on the wire bar). The specific operation is as follows: Since the tape cutting mechanism B600 is located below the wire bar, the tape will inevitably pass under the wire bar during the tape wrapping process. Therefore, the initial position of the tape roll is located to the lower left of the second support B301. With manual assistance, the free end of the tape is pulled diagonally from below the wire bar to a certain length in the opposite direction. The cutting plate B604b and the top pressure plate B603b are tilted upwards to support the tape. During winding, the top pressure plate B603b on the left side is lifted upwards, causing the tape to adhere to the bottom of the wire bar. The tape winding motor B305 drives the tape winding gear B302 to rotate clockwise. To avoid the tape, the tape cutting cylinder B604c and the top pressure cylinder B603c work sequentially, causing the free ends of both the cutting plate and the top pressure plate B603b to fall back (as shown in the image). Figure 30(As shown in state A), the tape passes over the cutting plate B604b and the top pressure plate B603b, wrapping around twice (or after other predetermined number of wraps). The tape winding gear B302 drives the tape to rotate from the lower right of the second stand B301 to its lower left. When the tape passes the middle top pressure plate B603b, the corresponding top pressure cylinder B603c is activated, causing the top pressure gear B603a to rotate clockwise, lifting the top pressure plate B603b upwards and pressing the tape. The tape cutting cylinder B604c is activated, lifting the cutting plate B604b clockwise (as shown in state A). Figure 30 (At position B), and then cut the tape.

[0085] Combination Figure 22 and Figures 31-32 It is known that the conveying mechanism B400 is located behind the horizontal seat B601, and includes a lower conveying unit B401 set on the mounting platform B101, an upper conveying unit B402 mounted above the lower conveying unit B401, and a lifting power mechanism B403 that drives the upper conveying unit B402 to rise and fall. The lower conveying unit B401 is a horizontally set conveying roller unit (the rollers of the conveying roller unit are unpowered rollers), and the upper conveying unit B402 provides conveying power. The lifting power mechanism B403 includes a portal frame B403a, a lifting power source fixed to the portal frame B403a, and a vertical mounting plate B403b driven to rise and fall by the lifting power source. The vertical mounting plate B403b is located above the lower conveying unit B401, and the upper conveying unit B402 is a synchronous belt drive mechanism set on the vertical mounting plate B403b (its driving power source B402a includes a motor and a reducer), located above the feed end of the upper conveying unit. When the wire rod moves onto the lower conveyor unit, the lifting power mechanism B403 drives the synchronous belt drive mechanism to descend to the upper surface of the wire rod. The first synchronous belt B402b is parallel to the lower conveyor unit, and when the synchronous belt drive mechanism is working, it provides forward movement force for the wire rod conveying. In this invention, the lower conveyor unit B401 provides support force for the wire rod. The lower conveyor unit B401 uses a conveyor roller. When subjected to the external force applied by the first synchronous belt B402b, the wire rod advances on the lower conveyor unit B401, thereby realizing continuous winding of the release belt and the tape.

[0086] In actual installation, the lifting power source includes a lifting cylinder B403d vertically mounted on the crossbeam of the portal frame B403a, which is connected to the vertical mounting base B403b. A pair of second slide rails B403c are symmetrically arranged on the legs of the portal frame B403a. Two sliders with sliding cooperation between the second slide rails B403c are arranged on the left and right sides of the vertical mounting base B403b, providing support for the upper conveying unit B402 and ensuring stable lifting and flexible height adjustment of the upper conveying unit B402. During operation, when the wire rod moves onto the lower conveying unit B401, the lifting power mechanism B403 drives the synchronous belt transmission mechanism to descend, causing the first synchronous belt B402b to act on the upper surface of the wire rod. The first synchronous belt B402b transmits power to the wire rod, causing it to continue moving forward on the lower conveying unit B401.

[0087] During actual installation, due to the weight of the wire rod, a first support platform B103 is installed on the second frame B100 on the feeding side of the demolding belt winding mechanism B200 (see...). Figure 21 ), used to support the wire bar, allowing it to smoothly pass through the center of the release belt winding gear B203; combined Figure 4 It can be seen that a second support platform B106 is installed on the rear side of the first support B201, and an upper pressure roller B105 is installed above the second support platform B106. The upper pressure roller B105 has a limiting function to prevent the head end of the wire bar from lifting up during the movement of the wire bar and affecting the winding of the demolding belt. The fixing shaft of the demolding belt fixing structure B204 is inclined relative to the wire bar so that the demolding belt is located on the rear side of the pressure roller. A portal-shaped support frame B104 (see figure) is installed on the mounting platform B101 located behind the demolding belt wrapping path. Figure 21 The support frame B104 provides support for the wire rods. Additionally, the front and rear ends of the support top plate of the support frame B104 are bent downwards, serving a guiding function to allow the wire rods to pass smoothly over the support top plate. The first support platform B103, the second support platform, the support frame B104, and the conveyor roller unit (the conveyor roller unit has a certain length to meet the requirements of the wire rods) are arranged sequentially at intervals to provide rigid support for the wire rods.

[0088] The present invention combines an insulating mat feeding machine and a wrapping machine to achieve automatic wrapping of wire bars. The specific process is as follows: Install the tray A303, filled with insulating pads, into place, and secure it with fastening bolts. During continuous feeding, the wire rod enters the wire rod support mechanism A700 through the feeding channel. After moving into place, the first and second limit cylinders A601 limit its ends. The insulating pad gripping device A500 adjusts the two gripping mechanisms A503 to enter the feeding station below. The insulating pad feeding pusher A302 simultaneously pushes the insulating pad (each push distance is one insulating pad width). When the insulating pad is pushed into place, the insulating pad pressing mechanism A307 presses down on the insulating pad below, and the gripping mechanism A503 adsorbs an insulating pad. The insulating pad gripping device A500 lifts the insulating pad and places it on both sides of the wire bar. After placement, the insulating pad auxiliary pusher 403 of the insulating pad auxiliary clamping mechanism closes to assist in clamping the wire bar and the insulating pads on both sides of the wire bar. The insulating pad gripping device A500 repeats the gripping action to grip another pair of insulating pads. During placement, the insulating pad auxiliary pusher 403 opens and descends below the gripping seat to avoid the gripping seat. The insulating pad gripping device A500 places two insulating pads on both sides of the wire bar, and the two wire bar clamping plates A504b close to clamp the wire bar and the insulating pads. The insulating pad gripping device A500 then conveys the clamped wire bar and insulating pads to the right for a certain length, allowing them to enter the wrapping machine B. When a section of wire with insulating pads on both sides enters the wrapping machine B, the limiting rod of the second limiting cylinder is pushed out to limit the two sides of the wire. The insulating pad gripping device A500 repeats the gripping and releasing action, thus achieving continuous feeding of insulating pads. When the insulating pad is too long, the excess portion is removed using the insulating pad cutting mechanism A200. During cutting, the insulating pad gripping device A500 moves two insulating pads from the feeding side of the material tray A303 and suspends them above the recycling box. The piston rod of the insulating pad cutting cylinder A202b extends outward, causing the first cutter A202c to pass under the insulating pad and cut it into two parts. The excess portion falls into the recycling box A203.

[0089] To ensure the quality of the wire rod winding, there is an overlap between the previous and next rounds of release tape on the wire rod. During winding, only the ends of the wire rod need to be wrapped with tape to prevent the release tape from loosening, thus ensuring the quality of the release tape winding: After the insulating pad is in place, the insulating pad gripping device A500 feeds the wire rod into the release tape winding mechanism B200 at a uniform speed. When the end of the wire rod passes through the second support platform B106, the free end of the release tape is manually placed on the wire rod. The release tape winding motor B202 drives the release tape winding gear B203 to rotate. During this process, it drives the release tape fixing structure B204 to rotate with it. The release tape roll is pulled and rotates relative to the fixed shaft, thereby releasing the release tape. During the winding process, since the release tape on the wire rod is wrapped in layers, it can be released after the second round of winding is completed, and the second round is used to fix the first round of the release tape. When the bar passes the second bar limiting mechanism B800, the limiting motor B805 drives the bidirectional lead screw B802 to rotate, causing the two limiting rollers B803 to move towards each other, thereby limiting the two sides of the bar and preventing the bar from deviating during the conveying process. As the front end of the wire rod moves to the second support B301, manual assistance is used to pull the free end of the tape to the opposite side, positioning the free end of the tape above the top pressure plate B603b (this helps to hold the free end of the tape in place). When the wire rod moves above the top pressure plate B603b, the left side of the top pressure plate B603b (which has sponge to protect the release belt) is lifted upwards, causing the tape to adhere to the release belt at the bottom of the wire rod. The tape winding motor B305 then drives the tape winding gear. When B302 rotates, the tape roll is released under force, thus achieving multi-turn winding of the tape (during the tape winding process, the free ends of the top pressure plate B603b and the cutting plate B604b rotate to the lower limit position to avoid the tape); when the tape finally passes the middle top pressure plate B603b, the top pressure plate B603b is lifted upward, thus pressing the tape upward, and the cutting plate on the right is lifted upward to cut the tape, thus completing the tape winding at the end of the wire rod and preventing the release strip from loosening; The wire bar continues to move forward. When the wire bar enters the conveyor mechanism B400, the synchronous belt drive mechanism of the conveyor mechanism B400 is activated, providing uniform forward power for the wire bar. The conveyor mechanism B400 drives the wire bar forward, wrapping and moving forward simultaneously to achieve uniform wrapping and ensure the consistency of the release belt density. After this section of the wire bar is wrapped, the wrapping machine stops working, and the insulation pad gripping device A200 repeats the gripping action. After placement, the above pushing action is repeated, and the wrapping machine is started to wrap the second section of the wire bar. This process is repeated until the insulation wrapping of the entire wire bar is completed. In this invention, after the tail end of the wire rod is wrapped, tape is first wrapped and cut, followed by the cutting of the release strip. The specific process is as follows: When the tail end of the wire rod passes the tape wrapping mechanism B300, the tail end of the wire rod is wrapped and fixed with tape in the same way as the head end of the wire rod, and then cut with the tape cutting mechanism; then the release strip cutting mechanism 500 is activated, and its horizontal cylinder 501 drives the release strip cutting cylinder 503 to move forward, so that the buffer structure moves to a position below the release strip. The release strip cutting cylinder 503 drives the upper pressure block 504a to descend and press down on the release strip. The upper pressure block 504a and the lower cutter 504b combine to cut the release strip, completing the wrapping of the wire rod. This invention wraps the tail end with tape first and then cuts the release strip, which can prevent the release strip from loosening.

[0090] When the specifications of the wire rod change, the height of the first stand B201 is finely adjusted using the lifting mechanism B700, thereby finely adjusting the center height of the demolding belt winding gear B203; the angle of the third stand B204c is adjusted according to the specifications of the wire rod, and the angle of the fixed shaft is adjusted by adjusting the angle of the third stand B204c, thereby adjusting the angle of the demolding belt winding to meet the requirements of wire rod wrapping.
