Description

Technical Field

[0001] This invention relates to the field of heating plate winding equipment, and more specifically, to a winding method and winding equipment for preventing short circuits between turns of an induction cooker heating plate. Background Technology

[0002] The manufacturing process of an induction cooker heating plate consists of a series of different production processes. Among them, the winding process is a very important process and the first process. The function of the winding equipment is to wind and fix the enameled wire to the bracket of the induction cooker heating plate.

[0003] In the existing technology, the heating plate bracket is generally wound sequentially from the inner circle to the outer circle during the winding process. Each circle requires 1-2 layers of enameled wire (mostly 2 layers). This will form a cross-wire structure on the heating plate, which will create contact surfaces between the enameled wires. If there are problems such as damage or pinhole defects in the two wires, it is easy to cause short circuits between turns after power is applied, resulting in safety accidents.

[0004] To address this, we propose a winding method and winding equipment to prevent short circuits between turns of the heating plate in an induction cooker, effectively solving some problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems. It provides a winding method and winding device to prevent short circuits between turns of the heating plate of an induction cooker. The method involves passing the enameled wire to be wound through the circular opening of the plate support from the top and bottom, and using two sets of auxiliary tapes to wind the upper and lower free ends of the enameled wire synchronously and concentrically on the front and back sides of the plate support. This ensures that the wire is wound alternately on both sides, effectively avoiding the occurrence of wire crossing. It eliminates the need for separate winding work on the upper and lower ends and the need to flip the wire during the winding process, thus simplifying the winding process.

[0006] The objective of this invention can be achieved through the following technical solution: a winding device for preventing short circuits between turns of an induction cooker heating plate, comprising an operating table and a plate support. A rotating column is mounted on the operating table via a motor. Limiting components are fixedly sleeved at the upper and lower ends of the rotating column. The plate support is located between a pair of limiting components, and clamps for clamping the plate support are installed at the upper front and rear ends of the operating table. The limiting component includes a winding column and a limiting plate that are connected by inner and outer sleeves. The winding column is magnetically sleeved on the rotating column. The end of the winding column near the plate support and exposed inside the limiting plate is the winding part. The plate support includes a pair of winding plates and multiple connecting strips fixed between the two. Each pair of winding plates has a round opening sleeved on the outside of the rotating column for the enameled wire to pass through. A winding space is reserved between the limiting plate and the winding plates.

[0007] The operating platform is fixedly installed on one side of the upper end of the rotating column with a take-up reel. The upper and lower ends of the take-up reel are respectively provided with storage cavities that match the two winding spaces. A second motor is installed at the bottom end of the take-up reel. The drive end of the second motor passes through the bottom end of the take-up reel and extends to the two storage cavities. An auxiliary tape is wound on both take-up shafts. A through groove is provided on the end wall of the take-up shaft near the rotating column. The auxiliary tape includes a winding tape and an insulating tape that are flush and fitted together. The winding tape has a winding groove for the enameled wire to be embedded and fitted together.

[0008] Furthermore, the clamp includes an electric slide rail fixedly mounted on the upper part of the operating table, an L-shaped frame mounted on the electric slide rail, a lower fixed flap fixedly connected to the inner wall of the L-shaped frame near its bottom side, an upper movable flap matching the lower fixed flap slidably connected to the inner wall of the L-shaped frame near its upper end, a screw rotatably connected to the top of the L-shaped frame, the lower end of the screw passing through the upper movable flap and rotatably connected to the lower fixed flap, and a handle rotatably connected to the screw at the top of the L-shaped frame. The L-shaped frame can move horizontally on the electric slide rail, and the upper movable flap can move up and down by rotating the screw, thereby clamping and limiting the disc support placed between a pair of limiting components in the front and back directions.

[0009] Furthermore, electromagnetic plates are embedded at both the upper and lower ends of the rotating column, and magnetic rings are embedded in both the upper and lower pairs of winding columns. When the limiting component is placed in the appropriate position, the electromagnetic plate at that position is activated to achieve a fixed connection between the limiting component and the rotating column, thereby driving the pair of limiting components to rotate for winding operation.

[0010] Furthermore, a protective sleeve is slidably connected to the circular opening of each pair of winding spools, and an annular groove for sliding the protective sleeve is provided on the circular opening. A circular hole for the enameled wire to pass through is provided on each pair of protective sleeves, and the two ends of the enameled wire pass through the circular hole and extend to the outside of the upper and lower spool supports respectively.

[0011] Furthermore, the rotating column and the winding column end walls are provided with interconnected vertical grooves that match the protective sleeve. The vertical grooves penetrate the upper and lower ends of the rotating column and the winding column in the vertical direction and extend horizontally to the outside of the winding column, facilitating the passage of the upper and lower ends of the enameled wire.

[0012] Furthermore, the winding tape is made of flexible rubber material, and the insulating tape is made of insulating material. The combined structure of the winding tape and the insulating tape is used to concentrically wind the enameled wire, thereby realizing that the enameled wire forms a spiral structure from the inside to the outside on the end face of the winding reel.

[0013] Furthermore, the upper and lower end faces of the winding reel are also fitted with insulating positioning frames that interlock with the insulating tape from the inside out. The insulating positioning frames are also spiral in shape. Each ring of the insulating positioning frame has a positioning groove on its outer bottom wall that fits into the top of the insulating tape. After the enameled wire is wound to the last turn, the winding tape that is in contact with the insulating tape is slowly detached from the inside out, leaving only the insulating tape. There are gaps between the rings of the insulating tape. At this time, the insulating positioning frames that match the gaps are embedded in the insulating tape to limit the insulating tape. After the insulating tape is limited, it is embedded in the positioning grooves. On the one hand, the insulating positioning frames with mechanical strength provide reinforcement and support for the enameled wire. On the other hand, the insulating positioning frames, together with the insulating tape, provide insulation and heat insulation for the enameled wire, reducing safety hazards.

[0014] A winding method for preventing short circuits between turns of an induction cooker heating plate includes the following steps:

[0015] Step 1: First, extend the protective sleeve of the enameled wire used for winding outwards through the upper and lower parts of the reel bracket. The free end of the enameled wire at the bottom passes through the vertical groove below and extends to the upper end of the limiting plate. The end of the enameled wire that fits into the vertical groove and the auxiliary tape pulled out from the lower storage cavity are wound together on the winding column. The free end of the enameled wire at the bottom is set in the same direction as the auxiliary tape. Then, put the reel bracket on the rotating column and leave a winding space between it and the limiting plate. Use a pair of clamps to fix the reel bracket. After the reel bracket is positioned, the winding preparation of the lower end face of the reel bracket is completed.

[0016] Step 2: Place the upper limiting component onto the rotating column, leaving a winding space between it and the upper end face of the disc support. Install the winding column and the limiting disc on the rotating column from front to back. Pull out the auxiliary tape located in the upper winding groove and together with the enameled wire passing through the vertical groove at the upper end face of the disc support, place it on the winding part of the winding column. Set the free end of the enameled wire in the same direction as the auxiliary tape at that location. Finally, attach the limiting disc to the winding column to complete the winding preparation of the upper end face of the disc support.

[0017] Step 3: Start motor one. Motor one drives a pair of limit components to rotate through the rotating column, thereby realizing the concentric rotation of the upper and lower auxiliary belts and the enameled wire cooperation structure. The free end of the enameled wire is wound into a spiral from the inside to the outside simultaneously on the upper and lower end faces of the disc support.

[0018] Step 4: After the enameled wire is wound to the outermost loop, turn off motor one, remove the remaining auxiliary tape from the take-up reel, and then remove the limiting assembly and reel bracket together from the outside of the rotating column to proceed with the subsequent wire assembly operations, specifically:

[0019] First, position the enameled wire on the upper surface of the reel support by removing the upper limiting component outwards. The enameled wire and the auxiliary tape form a tightly fitted spiral structure. At this point, place a positioning ring disc on the upper surface of the winding reel, which fits against the upper surface of the insulating tape, to limit the insulating tape. The winding tape is now exposed. Remove the winding tape from the inside out, leaving only the insulating tape. There are gaps between the rings of the insulating tape. Insert the insulating positioning frame, which matches the gap, into the insulating tape. The insulating positioning frame can be fixed to the reel support with bolts. After the insulating tape is limited, the rings are embedded in the positioning grooves. Similarly, after flipping the reel support, use the same positioning method for the enameled wire on the other end of the reel support.

[0020] Compared with the prior art, the advantages of this invention are:

[0021] (1) This scheme is to pass the enameled wire to be wound through the round opening on the disc support from the top and bottom, and to connect the two free ends of the enameled wire with two sets of auxiliary tapes respectively, and to perform synchronous-concentric winding on the front and back of the disc support. Specifically, the enameled wire is connected to the winding part of the limiting component at the point where it passes through the round opening and the end of the auxiliary tape to complete the winding preparation. The upper and lower end faces of the disc support are prepared for winding from bottom to top. Then, the rotating column drives a pair of limiting components to rotate, so that the two free ends of the enameled wire are synchronously-concentrically rotated from the inside to the outside in a spiral trajectory with the two sets of auxiliary tapes distributed on the top and bottom to form a spiral disc structure. This ensures that the wire is wound at intervals on the front and back, effectively avoiding the occurrence of cross wires. There is no need to wind the wire separately on the front and back of the two ends, and there is no need to flip the wire during the winding process, which shortens the winding time and simplifies the winding process.

[0022] (2) This solution is achieved by adding an auxiliary tape that winds synchronously with the enameled wire. The auxiliary tape is a strip structure composed of a winding tape and an insulating tape. The auxiliary tape rotates concentrically with the enameled wire to guide the winding trajectory of the enameled wire. After the winding work is completed, the cooperating structure of the reel support and a pair of limiting components is removed outward. Then, the enameled wire on the upper and lower end faces of the reel support is subsequently clamped. Before the clamping operation, the winding tape is first removed, and then the insulating clamping frame is used to clamp and attach the insulating tape to the enameled wire. On the one hand, the insulating clamping frame with mechanical strength provides reinforcement and support for the enameled wire. On the other hand, the insulating clamping frame, together with the insulating tape, provides insulation and heat insulation for the enameled wire, reducing safety hazards.

[0023] (3) This solution uses a protective sleeve that is slidably connected to the inner end wall of the disc support to limit the enameled wire. When the enameled wire and the auxiliary tape are positioned at the winding part of the limiting component after passing through the vertical groove, the rotation of a pair of limiting components is used to realize the spiral rotation of the enameled wire and the auxiliary tape from the inside to the outside. During the rotation, the added protective sleeve, annular groove and vertical groove are conducive to the enameled wire that is limited at the round opening of the disc support to rotate synchronously with the limiting component, and it is not easy for the middle part of the enameled wire to be pulled and broken during the rotation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] This invention discloses a winding device for preventing short circuits between turns of the heating plate in an induction cooker. Please refer to [link / reference]. Figure 1 and Figure 2 The system includes an operating platform 1 and a tray support 3. A rotating column 4 is mounted on the operating platform 1 via a motor. Limiting components are fixedly fitted at both the upper and lower ends of the rotating column 4. The tray support 3 is located between a pair of limiting components. Clamps for clamping the tray support 3 are installed at both the front and rear upper ends of the operating platform 1. The clamps include an electric slide rail 21 fixedly mounted on the upper end of the operating platform 1. An L-shaped frame 22 is mounted on the electric slide rail 21. A lower fixing flap 23 is fixedly connected to the inner wall of the L-shaped frame 22 near its bottom side. The lower fixing flap 23 is slidably connected to the inner wall of the L-shaped frame 22 near its upper end. The upper movable lobe 24 is matched with the screw 25 rotatably connected to the top of the L-shaped frame 22. The lower end of the screw 25 passes through the upper movable lobe 24 and is rotatably connected to the lower fixed lobe 23. The top of the L-shaped frame 22 is rotatably connected to the handle connected to the screw 25. The L-shaped frame 22 can move horizontally on the electric slide rail 21 and move the upper movable lobe 24 up and down by rotating the screw 25, thereby clamping and limiting the disc support 3 placed between a pair of limiting components in the front and back directions, so as to keep the disc support 3 stable during the winding process.

[0043] Please see Figures 2-3 The limiting component includes a winding post 5 and a limiting plate 6 connected by inner and outer sleeves. The winding post 5 is magnetically attached to the rotating post 4. The end of the winding post 5 near the plate support 3 and exposed inside the limiting plate 6 is the winding part. The plate support 3 includes a pair of winding plates 31 and multiple connecting strips 32 fixedly connected between the two. Each pair of winding plates 31 has a round opening that is sleeved on the outside of the rotating post 4 and used for the enameled wire 10 to pass through. A winding space is reserved between the limiting plate 6 and the winding plates 31. The outer diameter of the winding post 5 is larger than the inner diameter of the round opening. The end faces of the winding post 5 and the winding plates 31 can be rotatably contacted.

[0044] Electromagnetic plates are embedded at both the upper and lower ends of the rotating column 4, and magnetic rings are embedded in both the upper and lower winding columns 5. When the limiting component is placed in the appropriate position, the electromagnetic plate at that position is activated to achieve a fixed connection between the limiting component and the rotating column 4, thereby driving the pair of limiting components to rotate for winding operation.

[0045] Please see Figures 3-7 It should be noted that the pair of winding reels 31 have multiple slots with openings at the top and bottom. Protective sleeves 33 are slidably connected to the circular openings of both winding reels 31, and annular grooves for sliding the protective sleeves 33 are provided on the circular openings. Each pair of protective sleeves 33 has a circular hole for the enameled wire 10 to pass through. The two ends of the enameled wire 10 pass through the circular holes and extend to the outside of the upper and lower reel supports 3, respectively. Meanwhile, vertical grooves that are interconnected and match the protective sleeves 33 are provided on the end walls of the rotating column 4 and the winding column 5. These vertical grooves penetrate vertically through the upper and lower ends of the rotating column 4 and the winding column 5 and horizontally extend to the outside of the winding column 5. To facilitate the passage of the enameled wire 10 through its upper and lower ends, a protective sleeve 33 is slidably connected to the inner end wall of the disc support 3 to limit and protect the enameled wire 10. After the enameled wire 10 and the auxiliary tape 9, which have passed through the vertical groove, are positioned at the winding part of the limiting component, the rotation of a pair of limiting components enables the enameled wire 10 and the auxiliary tape 9 to rotate spirally from the inside out. During the rotation, the added protective sleeve 33, annular groove, and vertical groove help the enameled wire 10, which is limited at the circular opening of the disc support 3, to rotate synchronously with the limiting component, making it less likely that the middle part of the enameled wire 10 will be pulled and broken during the rotation.

[0046] When the end of the enameled wire 10 that passes through the round opening is in contact with the outer end face of the upper and lower winding discs 31 respectively, the upper and lower free ends of the enameled wire 10 that pass through the round opening are reserved with equal lengths. The upper and lower free ends of the enameled wire 10 are rotated synchronously from the inside to the outside. The free ends of the enameled wire 10 are rotated to the outermost ring of the disc support 3 and the winding stops. This realizes that the enameled wire 10 rotates synchronously and concentrically on the upper and lower end faces of the disc support 3, ensuring that the wires are wound alternately on both sides, effectively avoiding the occurrence of wire crossing, preventing short circuits between the turns of the heating disc, and eliminating the need for separate winding work on the upper and lower end faces, as well as the need to flip the wires during the winding process, thus shortening the winding time and simplifying the winding process.

[0047] Example 2:

[0048] Based on Embodiment 1, this solution adds a winding reel 7 horizontally positioned at the top of the operating table 1, which is also horizontally aligned with the rotating column 4. Auxiliary tapes 9, matching the spatial positions of the two winding sections, are wound vertically within the winding reel 7. These auxiliary tapes 9 work in conjunction with the enameled wire 10 to perform a concentric spiral winding operation, providing support and guidance for the winding of the enameled wire 10. Specifically, the following applies:

[0049] Please see Figures 4-7 The operating table 1 is fixedly installed on one side of the upper end of the rotating column 4 with a winding reel 7. The upper and lower ends of the winding reel 7 are respectively provided with storage cavities that match the two winding spaces. The bottom end of the winding reel 7 is equipped with a second motor. The drive end of the second motor passes through the bottom end of the winding reel 7 and extends to the two storage cavities. The two winding shafts 8 are each wound with an auxiliary tape 9. The auxiliary tape 9 includes a winding tape 91 and an insulating tape 92 that are flush and attached to each other. The winding tape 91 is provided with a winding groove for the enameled wire 10 to be embedded and attached. The winding tape 91 is made of flexible rubber material, and the insulating tape 92 is made of insulating material. The matching structure formed by the winding tape 91 and the insulating tape 92 is used to wind the enameled wire 10 concentrically, thereby realizing that the enameled wire 10 forms a spiral structure from the inside to the outside on the end face of the winding reel 31.

[0050] After the disc bracket 3 is positioned on the lower limiting component using a pair of clamps, the winding portion on the lower limiting component is located within the winding space. The auxiliary tape 9 located in the lower receiving cavity is passed through the through slot and fixedly sleeved onto the outer wall of the winding portion. The lower free end of the enameled wire 10 passes through the protective sleeve 33, the lower vertical slot, and extends to the upper end of the limiting disc 6. The enameled wire 10 exiting the vertical slot is in contact with the auxiliary tape 9 wound on the winding post 5. The lower free end of the enameled wire 10 is set in the same direction as the auxiliary tape 9. Then, the disc bracket 3 is sleeved on the rotating post 4, leaving a winding space between it and the limiting disc 6. The disc bracket 3 is fixed using a pair of clamps. After the disc bracket 3 is positioned, the upper limiting component is similarly... The component is mounted on the rotating column 4 and a winding space is reserved between it and the upper end face of the tray support 3. When installing the upper limiting component, the winding column 5 can be mounted on the rotating column 4 and the winding column 5 can be movably attached to the upper end wall of the winding tray 31. The auxiliary tape 9 located in the upper winding groove is pulled out and fixedly mounted on the winding part of the winding column 5. The upper free end of the enameled wire 10 passes through the protective sleeve 33 and the upper vertical groove in sequence and extends outward from the position attached to the winding tray 31. Similarly, the enameled wire 10 that passes through the vertical groove is attached to the auxiliary tape 9 wound on the winding column 5. The upper free end of the enameled wire 10 is set in the same direction as the auxiliary tape 9 at that position. Finally, the limiting tray 6 is mounted on the winding column 5 to complete the preparation work before winding.

[0051] Please see Figures 9-14 After the enameled wire 10 passes through the round opening, it is immediately fixed and sleeved on the winding part of the limiting component together with the port of the auxiliary tape 9. The enameled wire 10 and the auxiliary tape 9 are synchronously stacked and spirally rotated from the inside to the outside in the winding space. The upper and lower free ends of the enameled wire 10 are synchronously and concentrically rotated from the inside to the outside in a spiral trajectory with the two sets of auxiliary tapes 9 distributed on the upper and lower sides to form a spiral disk structure. The auxiliary tape 9 is used to cooperate with the enameled wire 10 to perform a concentric spiral winding operation, so as to support and guide the winding of the enameled wire 10. After the winding work is completed, the winding tape 91 is detached from the inside to the outside, leaving only the structure of the insulation tape 92 and the enameled wire 10. The spiral gap formed between the layers of the insulation tape 92 is exposed. The end of the insulation tape 92 is trimmed. The detached winding tape 91 can be re-attached and wound into the winding reel 7 with another insulation tape 92 for subsequent use.

[0052] The upper and lower ends of the winding reel 31 are also fitted with insulating positioning frames 12 that are interlocked with the insulating strip 92 from the inside to the outside. The insulating positioning frames 12 are also spiral-shaped. Each ring of the insulating positioning frame 12 has a positioning groove 121 on the bottom wall of its outer side that fits into the top of the insulating strip 92. After the enameled wire 10 is wound to the last turn, the winding strip 91 that is in contact with the insulating strip 92 is slowly detached from the inside to the outside, leaving only the insulating strip 92. There are gaps between the rings of the insulating strip 92. At this time, the insulating positioning frames 12 that match the gaps are embedded in the insulating strip 92 to limit the insulating strip 92. After the insulating strip 92 is limited, it is embedded in the positioning groove 121. On the one hand, the insulating positioning frames 12 with mechanical strength provide reinforcement and support for the enameled wire 10. On the other hand, the insulating positioning frames 12, together with the insulating strip 92, provide insulation and heat insulation for the enameled wire 10, reducing safety hazards.

[0053] In conjunction with Embodiments 1 and 2, a winding method for preventing short circuits between turns of an induction cooker heating plate includes the following steps:

[0054] Step 1: First, extend the enameled wire 10 used for winding outward through the protective sleeve 33 of the reel bracket 3. The free end of the enameled wire 10 at the bottom passes through the vertical groove below and extends to the upper end of the limiting plate 6. The end of the enameled wire 10 that fits into the vertical groove and the auxiliary tape 9 pulled out from the lower storage cavity are wound together on the winding post 5. The free end of the enameled wire 10 at the bottom is set in the same direction as the auxiliary tape 9. Then, put the reel bracket 3 on the rotating post 4 and leave a winding space between it and the limiting plate 6. Use a pair of clamps to fix the reel bracket 3. After the reel bracket 3 is positioned, the winding preparation of the lower end face of the reel bracket 3 is completed.

[0055] Step 2: Place the upper limiting component on the rotating column 4 and leave a winding space between it and the upper end face of the disc support 3. Install the winding column 5 and the limiting disc 6 on the rotating column 4. Pull out the auxiliary tape 9 located in the upper winding groove and put it together with the enameled wire 10 that passes through the vertical groove at the upper end face of the disc support 3 on the winding part of the winding column 5. The free end of the enameled wire 10 is set in the same direction as the auxiliary tape 9 at this location. Finally, put the limiting disc 6 on the winding column 5 to complete the winding preparation of the upper end face of the disc support 3.

[0056] Step 3: Start motor 1. Motor 1 drives a pair of limit components to rotate through rotating column 4, thereby realizing the concentric rotation of the upper and lower auxiliary belts 9 and the enameled wire 10. The free end of the enameled wire 10 is wound into a spiral from the inside to the outside on the upper and lower end faces of the disc support 3.

[0057] Step 4: After the enameled wire 10 is wound to the outermost loop, turn off motor 1, remove the remaining auxiliary tape 9 from the take-up reel 7, and then remove the limiting assembly and reel bracket 3 together from the outside of the rotating column 4 to proceed with the subsequent wire reeling operation, specifically:

[0058] First, position the enameled wire 10 on the upper surface of the tray support 3. Remove the upper limiting component outwards. The enameled wire 10 and the auxiliary tape 9 form a tightly fitted spiral structure. At this time, place a positioning ring 11 on the upper surface of the winding tray 31, which fits against the upper surface of the insulating tape 92, to limit the insulating tape 92. At this time, the winding tape 91 is exposed. Remove the winding tape 91 from the inside out, leaving only the insulating tape 92. There are gaps between the rings of the insulating tape 92. Embed the insulating positioning frame 12, which matches the gap, into the insulating tape 92. The insulating positioning frame 12 can be fixed to the tray support 3 with bolts. After the insulating tape 92 is limited, it is embedded in the positioning groove 121. Similarly, after flipping the tray support 3, the same positioning method can be used for the enameled wire 10 on the other end of the tray support 3.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.

5. A winding method for preventing short circuits between turns of an induction cooker heating plate, comprising a winding device for preventing short circuits between turns of an induction cooker heating plate as described in any one of claims 1-4, characterized in that: Includes the following steps: Step 1: First, the enameled wire (10) used for winding passes through the protective sleeve (33) of the disc bracket (3) and extends outward. The free end of the enameled wire (10) passes through the vertical groove below and extends to the upper end of the limiting disc (6). The end of the enameled wire (10) that fits the vertical groove and the auxiliary tape (9) pulled out from the lower storage cavity are wound together on the winding post (5). The free end of the enameled wire (10) is set in the same direction as the auxiliary tape (9). Then, the disc bracket (3) is placed on the rotating post (4) and a winding space is reserved between it and the limiting disc (6). The disc bracket (3) is fixed with a pair of clamps. After the disc bracket (3) is positioned, the winding preparation of the lower end face of the disc bracket (3) is completed. Step 2: Place the upper limiting component on the rotating column (4) and leave a winding space between it and the upper end face of the disc bracket (3). Install the winding column (5) and the limiting disc (6) on the rotating column (4) from front to back. Pull out the auxiliary tape (9) located in the upper winding groove and put it together with the enameled wire (10) that passes through the vertical groove at the upper end face of the disc bracket (3) on the winding part of the winding column (5). The free end of the enameled wire (10) is set in the same direction as the auxiliary tape (9) at that place. Finally, put the limiting disc (6) on the winding column (5) to complete the winding preparation of the upper end face of the disc bracket (3). Step 3: Start motor 1. Motor 1 drives a pair of limit components to rotate through rotating column (4), thereby realizing the concentric rotation of the upper and lower auxiliary belts (9) and the enameled wire (10) in the cooperative structure. The free end of the enameled wire (10) is wound in a spiral from the inside to the outside at the upper and lower end faces of the disc support (3). Step 4: After the enameled wire (10) is wound to the outermost loop, turn off motor 1, remove the remaining auxiliary tape (9) from the take-up reel (7), and then remove the limiting assembly and the reel bracket (3) together from the outside of the rotating column (4) for subsequent wire reeling operations, specifically: First, the enameled wire (10) on the upper surface of the tray support (3) is positioned. The upper limiting component is removed outward. The enameled wire (10) and the auxiliary tape (9) form a tightly fitted spiral structure. At this time, a positioning ring (11) that fits against the upper surface of the insulating tape (92) is placed on the upper surface of the winding tray (31) to limit the insulating tape (92). At this time, the winding tape (91) is exposed. The winding tape (91) is removed from the inside to the outside, leaving only the winding tape (91) exposed. The insulating tape (92) has gaps between its rings. An insulating positioning frame (12) matching the gap is embedded in the insulating tape (92). The insulating positioning frame (12) and the disc support (3) can be fixed by bolts. After the insulating tape (92) is limited, it is embedded in the positioning groove (121) ring by ring. Similarly, after flipping the disc support (3), the same positioning method can be used for the enameled wire (10) on the other end face of the disc support (3).
