Description

Technical Field

[0001] This invention belongs to the field of transformer technology. Background Technology

[0002] In the field of transformer manufacturing, the waist joint 2 of the GU can-shaped magnetic core transformer 6 usually needs to be wrapped with several turns of insulating tape 3 to enhance the mechanical strength and insulation performance of the product.

[0003] Currently, although there are fully automated wrapping equipment in the industry to achieve this process, such as systems that use multi-axis robotic arms to grab tape and perform precise application, these systems usually achieve automation through visual positioning and complex motion control.

[0004] However, these fully automated equipment have significant drawbacks: First, the equipment has a complex structure, relying on high-precision servo positioning and complex program control, resulting in high manufacturing and maintenance costs; second, since the winding action of each transformer is completed independently, including steps such as lead-in, winding, and cutting, the overall production cycle is limited, making it difficult to meet the extreme pursuit of efficiency in large-scale mass production; third, the complex mechanism and control also bring a higher failure rate, affecting the continuous and stable operation of the production line.

[0005] In addition, another common approach to full automation is to use a dedicated single-station wrapping machine. Although it can achieve automation, it can usually only clamp one transformer at a time. When wrapping, the loading and unloading time and the processing time cannot overlap, resulting in low equipment utilization and a bottleneck in production capacity per unit time. Summary of the Invention

[0006] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a winding process system for GU can-shaped magnetic core transformers, which integrates multiple processes such as feeding, pre-bonding, winding, and unloading into a continuous motion.

[0007] Technical solution: To achieve the above objectives, the present invention provides a wrapping process system for a GU-shaped core transformer, comprising a rotating turntable with a plurality of rotating seats arranged in a circular array on the turntable; each rotating seat has a clamping platform, each clamping platform has a clamping device, and each clamping device fixes and clamps the lower end of a GU-shaped core transformer waiting to be wrapped with insulating tape; thereby enabling a plurality of GU-shaped core transformers waiting to be wrapped with insulating tape to be clamped in a circular array on the rotating turntable;

[0008] A portion of the space containing the annular rotating turntable is designated as the loading and unloading area. As the annular rotating turntable rotates continuously, several rotating seats will pass through the loading and unloading area in succession.

[0009] It also includes a taut tape drawn from the tape lead-out device, which crosses the waist of several GU-shaped core transformers away from the geometric center of the rotating disk in a clockwise direction, excluding the loading and unloading areas; a section of tape between any two adjacent GU-shaped core transformers excluding the loading and unloading areas is denoted as a straight chord segment of the tape, and the tape that crosses the waist of each GU-shaped core transformer is denoted as a partially bonded arc segment of the tape; the adhesive side of the partially bonded arc segment of the tape is bonded to the waist of the GU-shaped core transformer;

[0010] The straight chord segment of the tape closest to the end of the tape is referred to as the end tape straight chord segment; it also includes a linear expansion joint parallel to the end tape straight chord segment, and a linear suction strip is fixedly connected to the end of the expansion rod of the linear expansion joint along the length direction.

[0011] Furthermore, one side of the linear adsorption strip is an adsorption surface with a negative pressure adsorption mesh array; an electric heating metal wire or sharp blade is provided at the end of the adsorption surface away from the linear expansion joint; a pusher is vertically connected to one side of the linear expansion joint, and the pusher is installed on a fixed support; the pusher can drive the linear expansion joint to move in the vertical direction of its own length.

[0012] Furthermore, the GU can-shaped magnetic core transformer, which is clamped by the clamp, is coaxial with the rotating base directly below it.

[0013] Furthermore, the rotating seat itself has damping, requiring an external torque exceeding a certain threshold to rotate.

[0014] Furthermore, each clamping platform is provided with a perforated slot for the lower lead wire of the GU can-shaped magnetic core transformer to pass through;

[0015] Furthermore, there are six groups of GU-shaped core transformers awaiting wrapping with insulating tape, which are sequentially labeled as the first GU-shaped core transformer, the second GU-shaped core transformer, the third GU-shaped core transformer, the fourth GU-shaped core transformer, the fifth GU-shaped core transformer, and the sixth GU-shaped core transformer in a clockwise direction; among them, the sixth GU-shaped core transformer is in the loading and unloading area; the straight chord section of tape between the fourth and fifth GU-shaped core transformers is the end straight chord section of tape.

[0016] Furthermore, with both the pusher and the linear expansion joint extended, the adsorption surface of the linear adsorption strip is parallel to and fits against the back of the straight chord section of the end tape, and the heating metal wire on the adsorption surface is in contact with the end of the straight chord section of the end tape away from the fifth GU can-shaped magnetic core transformer.

[0017] Furthermore, a specific process of a wrapping process system for a GU can-shaped magnetic core transformer is characterized by: Step 1, controlling the linear expansion joint and the pusher to extend in sequence, the adsorption surface of the linear adsorption strip is parallel to the back of the straight chord section of the end tape, and the heating metal wire on the adsorption surface just contacts the end of the straight chord section of the end tape away from the fifth GU can-shaped magnetic core transformer.

[0018] Step two: The adsorption surface generates a negative pressure adsorption force, which makes the straight chord segment of the end tape stably adhere to the adsorption surface of the straight adsorption strip; at the same time, the heating wire is briefly energized, which makes the heating wire quickly cut off the end of the straight chord segment of the end tape away from the fifth GU can-shaped magnetic core transformer. Since the straight chord segment of the end tape is in the state of being adsorbed by the adsorption surface of the straight adsorption strip at this time, the straight chord segment of the end tape that is cut off at one end still remains in place.

[0019] Step 3: The pusher applies a thrust to increase the pressure between the adsorption surface of the straight adsorption bar and the outer circumference of the waist of the fifth GU-shaped core transformer. The telescopic rod retracts, and the straight adsorption bar follows the telescopic rod in a straight line along its own length. Under the action of rolling friction, the adsorption surface of the straight adsorption bar drives the fifth GU-shaped core transformer and the synchronously rotating turntable to rotate around the axis. This causes the fifth GU-shaped core transformer to roll relative to the extension direction of the adsorption surface of the straight adsorption bar. The straight chord segment of the end tape adsorbed on the adsorption surface of the straight adsorption bar gradually wraps around the outer circumference of the fifth GU-shaped core transformer. When the telescopic rod is fully retracted, the original straight chord segment of the end tape is transformed into a tightly wrapped insulating tape body on the waist of the fifth GU-shaped core transformer, and the straight adsorption bar is completely separated from the fifth GU-shaped core transformer.

[0020] Step four: Control the rotating turntable to rotate clockwise by °, and the tape lead-out device adaptively leads out a further section of taut tape; at this time, the original fifth GU can-shaped magnetic core transformer arrives at the loading and unloading area, and the original sixth GU can-shaped magnetic core transformer in the loading and unloading area arrives at the position of the first GU can-shaped magnetic core transformer in the initial state; then the robot arm releases the clamped state of the already wrapped fifth GU can-shaped magnetic core transformer in the loading and unloading area and takes it out for unloading, while the robot arm re-clamps a new unwrapped GU can-shaped magnetic core transformer on the clamp on the rotating seat in the loading and unloading area; this completes one work cycle, and the device just returns to the "initial state".

[0021] Beneficial effects: The innovation of this invention lies mainly in its ingenious system configuration and automated process, as detailed below:

[0022] Continuous production line operation mode: It adopts a horizontal annular rotating turntable and a circular array of workstations, integrating multiple processes such as loading, pre-bonding, wrapping, and unloading into a continuous motion. Through the intermittent rotation of the turntable, transformers at different workstations can be processed simultaneously.

[0023] The "one-tape-for-multiple-use" pre-layout structure utilizes a single continuous tape to simultaneously wrap around the waist of multiple transformers awaiting wrapping, forming multiple "locally bonded tape arc segments" and "straight chord segments." This design allows a single tape to serve multiple workpieces simultaneously, eliminating the need for individual tape drawing and cutting for each workpiece and simplifying the material supply system.

[0024] The integrated actuator combines adsorption, cutting, and rolling: it first adsorbs and fixes the tape segment to be wrapped, then instantly melts it to separate it from the main tape, and finally, through linear motion combined with rolling friction, tightly and smoothly rolls the adsorbed tape segment around the transformer waist in one continuous process; simultaneously, a damped rotating seat clamps the transformer. During the wrapping process, the positive pressure exerted by the linear adsorption strip on the transformer waist generates sufficient rolling friction to overcome the damping of the rotating seat, driving the transformer to rotate passively, thus completing the autonomous wrapping. This design eliminates the need for a separate rotary drive motor for each station, simplifying the structure and significantly reducing system cost and complexity.

[0025] Parallelism and synchronization of functions at each workstation: Within a single work cycle, the system enables parallel processing of multiple processes: while one workstation is performing wrapping operations, other workstations are pre-bonding tape, and simultaneously, the loading and unloading workstations are unloading finished products and loading blanks. This high degree of parallelism ensures maximum equipment utilization and production cycle time. Attached Figure Description

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] like Figures 1 to 6 The diagram illustrates a winding process system for a GU can-shaped magnetic core transformer 6. The GU can-shaped magnetic core transformer 6 comprises a frame, a can-shaped magnetic core, coil windings, and internal epoxy resin filling. The GU can-shaped magnetic core transformer 6 is cylindrical in shape. Figure 1 As shown, in the final process, several turns of insulating tape 3 need to be wrapped around the waist seam 2 of the GU can-shaped magnetic core transformer 6 to enhance mechanical strength and insulation performance. This solution provides an automated batch wrapping system, the specific solution of which is as follows:

[0034] like Figures 2 to 5 As shown, the device includes a horizontally annular rotating turntable 5. A driving device can drive the rotating turntable 5 to rotate around its axis. Several rotating seats 7, which can rotate around their own axes, are installed in a circular array on the rotating turntable 5. The rotating seats 7 are damped and have built-in bearings and dampers. The damping threshold is set to 0.5 N·m to 2 N·m to ensure that they do not rotate during normal transportation and only rotate when subjected to external force during wrapping. They need to be subjected to external torque exceeding a certain threshold to rotate. Each rotating seat 7 is equipped with a clamping platform 25, and each clamping platform 25 is equipped with a clamp 21. The clamp 21 uses pneumatic or electric grippers with adjustable clamping force ranging from 5 N to 20 N to accommodate transformers of different sizes. Each clamp 21 is fixedly clamped to the lower end of a GU can-shaped magnetic core transformer 6 waiting to be wrapped with insulating tape.

[0035] The GU-shaped core transformer 6, clamped by the clamp 21, is coaxial with the rotating base 7 directly below it; thus, several GU-shaped core transformers 6, awaiting wrapping with insulating tape, are arranged in a circular array on the rotating turntable 5; each clamping platform 25 is provided with a perforated slot 20 for the lower lead wire 60 of the GU-shaped core transformer 6 to pass through. The width of the perforated slot 20 is 2mm to 5mm to ensure that the lead wire 60 passes through smoothly without damage.

[0036] A portion of the space containing the annular rotating turntable 5 is designated as the loading / unloading area 30. As the annular rotating turntable 5 rotates continuously, several rotating seats 7 will successively pass through the loading / unloading area 30. The system also includes a taut tape 4 drawn out from a tape lead-out device. The tape lead-out device includes a tape reel, a tension controller, and guide rollers to ensure that the tape 4 is drawn out with a constant tension, set to 0.1N to 0.5N. The tape 4 is a polyimide tape or a PET insulating tape with a thickness of 0.05mm to 0.1mm, possessing high insulation and adhesion.

[0037] The tape 4 passes over the waist of several GU-shaped magnetic core transformers 6 away from the geometric center of the rotating turntable 5 in a clockwise direction, excluding the loading and unloading area 30.

[0038] like Figure 2 A section of tape 4 between any two adjacent GU-shaped core transformers 6, excluding the loading and unloading area 30, is designated as tape straight chord segment 4a. Tape 4 wrapped across the waist of each GU-shaped core transformer 6 is designated as tape partial bonding arc segment 4b. The adhesive side of tape partial bonding arc segment 4b is bonded to the waist of the GU-shaped core transformer 6. Tape partial bonding arc segment 4b is temporarily bonded to the waist of the transformer by the self-adhesiveness of the tape, with an adhesive force of 0.2 N / cm to 0.8 N / cm, ensuring it does not detach during wrapping but is easy to wind in subsequent steps. The section of tape straight chord segment 4a closest to the end of tape 4 is designated as end tape straight chord segment 4aa.

[0039] like Figure 2 As shown, there are six groups of GU-shaped core transformers 6 waiting to be wrapped with insulating tape, sequentially labeled as the first GU-shaped core transformer 6a, the second GU-shaped core transformer 6b, the third GU-shaped core transformer 6c, the fourth GU-shaped core transformer 6d, the fifth GU-shaped core transformer 6e, and the sixth GU-shaped core transformer 6f in a clockwise direction; the sixth GU-shaped core transformer 6f is located in the loading / unloading area 30; the straight chord section 4a of the tape between the fourth GU-shaped core transformer 6d and the fifth GU-shaped core transformer 6e is the end straight chord section 4aa. This circular array layout makes full use of space, enables continuous production, and improves efficiency. The number of stations on the rotary table 5 can be adjusted according to requirements, such as 6 stations, 8 stations, etc.

[0040] It also includes a linear expansion joint 10 parallel to the straight chord segment 4aa of the end tape. A linear suction strip 9 is fixedly connected to the end of the expansion rod 13 of the linear expansion joint 10 along its length direction. Figure 6 One side of the linear adsorption strip 9 is an adsorption surface 14 with a negative pressure adsorption mesh array; the linear adsorption strip 9 is made of aluminum alloy, and the internal hollow negative pressure chamber is connected to a vacuum pump through a negative pressure suction hose 16. The mesh diameter of the adsorption surface 14 is 0.5mm to 1mm, and the negative pressure value is -0.05MPa to -0.1MPa.

[0041] An electric heating wire 15 or a sharp blade is provided at the end of the adsorption surface 14 away from the linear expansion joint 10; the electric heating wire 5 is a nickel-chromium alloy wire with a diameter of 0.2 mm to 0.5 mm, which heats up to about 300°C instantly after being energized to melt the tape. A pusher 11 is vertically connected to one side of the linear expansion joint 10, and the pusher 11 is installed on the fixed support 12; the pusher 11 can drive the linear expansion joint 10 to move in the vertical direction of its own length.

[0042] With both the pusher 11 and the linear expansion joint 10 extended, the adsorption surface 14 of the linear adsorption strip 9 is perfectly parallel to and adheres to the back of the straight chord segment 4aa of the end tape, and the heating wire 15 on the adsorption surface 14 is in contact with the end of the straight chord segment 4aa of the end tape away from the fifth GU can-shaped magnetic core transformer 6e. Through precise positioning, the parallelism error between the linear adsorption strip 9 and the straight chord segment 4aa of the end tape is less than 0.1 mm, ensuring accurate adsorption and cutting.

[0043] It also includes a negative pressure suction hose 16 that connects to the hollow negative pressure chamber inside the linear adsorption strip 9. Under the suction of the negative pressure suction hose 16, the adsorption surface 14 with the negative pressure adsorption mesh array generates a negative pressure adsorption force. The inner diameter of the negative pressure suction hose 16 is 4mm to 8mm, and it is connected to a vacuum pump with a flow rate of 10L / min to 20L / min to ensure rapid generation of negative pressure.

[0044] Work methods:

[0045] In the initial state, the taut tape 4, drawn from the tape lead-out device, sequentially crosses the waist of the first GU-shaped core transformer 6a, the second GU-shaped core transformer 6b, the third GU-shaped core transformer 6c, the fourth GU-shaped core transformer 6d, and the fifth GU-shaped core transformer 6e on the upper side of the rotating turntable 5 in a clockwise direction, and partially bonds them, forming five tape partially bonded arc segments 4b. In the initial state, the rotating turntable 5 is stationary, all GU-shaped core transformers 6 are fixed by the clamps 21, and the tape 4 is taut under tension, forming a stable multi-segment bond.

[0046] The sixth GU can-shaped magnetic core transformer 6f is located in the loading and unloading area 30; the straight chord section 4a of the tape between the fourth GU can-shaped magnetic core transformer 6d and the fifth GU can-shaped magnetic core transformer 6e is the end tape straight chord section 4aa; the end tape straight chord section 4aa is bonded to the waist of the fifth GU can-shaped magnetic core transformer 6e by the tape partial bonding arc section 4b near the end of the fifth GU can-shaped magnetic core transformer 6e.

[0047] Step 1: Using the PLC control system, the linear expansion joint 10 and the pusher 11 extend sequentially, ensuring that the adsorption surface 14 of the linear adsorption strip 9 is parallel to and in contact with the back of the straight chord segment 4aa of the end tape, and that the heating wire 15 on the adsorption surface 14 is in contact with the end of the straight chord segment 4aa of the end tape furthest from the fifth GU-shaped magnetic core transformer 6e. Specifically, the linear expansion joint 10 is first extended to bring the linear adsorption strip 9 close to the straight chord segment 4aa of the end tape, and then the pusher 11 is extended and its position is finely adjusted to ensure that the adsorption surface 14 is parallel to and in contact with the back of the straight chord segment 4aa of the end tape, and that the heating wire 5 contacts the end point.

[0048] Step 2: Control the negative pressure suction hose 16 to perform a suction action, so that the adsorption surface 14 with the negative pressure adsorption mesh array generates a negative pressure adsorption force, and forms an adsorption force on the straight chord section 4aa of the end tape, so that the straight chord section 4aa of the end tape is stably attached to the adsorption surface 14 of the straight adsorption strip 9.

[0049] Simultaneously, the heating wire 15 is briefly energized, causing it to quickly sever the end of the tape's straight chord segment 4aa that is furthest from the fifth GU-shaped magnetic core transformer 6e. Since the tape's straight chord segment 4aa is currently attracted by the adsorption surface 14 of the straight adsorption strip 9, the severed segment remains in place and does not fall due to gravity. The heating wire 5 is energized for 0.3 seconds with a current of 2A to 5A, ensuring rapid melting of the tape without burning.

[0050] Step three: Control the pusher 11 to apply a certain pushing force, thereby increasing the pressure between the adsorption surface 14 of the linear adsorption bar 9 and the outer peripheral surface of the waist of the fifth GU-shaped core transformer 6e; then, control the telescopic rod 13 of the linear telescoping device 10 to retract. As the linear adsorption bar 9 follows the telescopic rod 13 in a linear motion along its own length, the adsorption surface 14 of the linear adsorption bar 9, under the action of rolling friction, drives the fifth GU-shaped core transformer 6e and the synchronously rotating turntable 5 to rotate around the axis, thereby causing the fifth GU-shaped core transformer to... The device 6e rolls relative to the extension direction of the adsorption surface 14 of the straight adsorption strip 9, thereby gradually winding the end chord segment 4aa of the adhesive tape adsorbed on the adsorption surface 14 of the straight adsorption strip 9 around the outer periphery of the fifth GU can-shaped magnetic core transformer 6e. When the telescopic rod 13 is fully retracted, the original end chord segment 4aa of the adhesive tape is transformed into a tightly wrapped insulating tape body 3 around the waist of the fifth GU can-shaped magnetic core transformer 6e, and the straight adsorption strip 9 is completely separated from the fifth GU can-shaped magnetic core transformer 6e; thus, the wrapping process of one GU can-shaped magnetic core transformer 6 is completed. The retraction speed of the straight telescopic device 10 in this step is 10mm / s to 50mm / s, adjusted according to the tape width and the number of wrapping turns. During the rolling process, the fifth GU can-shaped magnetic core transformer 6e rotates multiple times, for example, 3 to 5 times, forming a tightly wrapped insulating tape body 3. The tape overlap rate of the wrapped body 3 is controlled between 50% and 70% to ensure insulation performance.

[0051] Step four: Control the rotating turntable 5 to rotate 60° clockwise, and the tape lead-out device adaptively leads out a taut section of tape 4; at this time, the original fifth GU can-shaped magnetic core transformer 6e reaches the loading and unloading area 30, and the original sixth GU can-shaped magnetic core transformer 6f in the loading and unloading area 30 reaches the position of the first GU can-shaped magnetic core transformer 6a in the initial state.

[0052] Then, the robotic arm releases the already wrapped fifth GU-shaped core transformer 6e from the loading / unloading area 30 and removes it for unloading. Simultaneously, the robotic arm re-clamps a new, unwrapped GU-shaped core transformer 6 onto the clamp 21 on the rotating seat 7 in the loading / unloading area 30; this completes one work cycle, and the device returns to its "initial state". The robotic arm is a four-axis or six-axis industrial robot, with a loading / unloading time controlled within 2 seconds. The rotation time of the rotary table 5 is 1 second, and the entire work cycle is 5 to 10 seconds, enabling high-speed mass production. The tape lead-out device synchronously leads out the tape as the rotary table 5 rotates, with the lead-out length matching the circumference of the rotary table to ensure that the tape is always taut.

[0053] By continuously and periodically running "Step One" to "Step Four" according to the above pattern, batch operation can be achieved. This system, through automated design, significantly improves winding efficiency and consistency, reduces manual intervention, and lowers production costs. Simultaneously, its modular design facilitates maintenance and adjustment, adapting to different specifications of GU-shaped core transformers.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

Under the action of rolling friction, the adsorption surface (14) of the linear adsorption bar (9) drives the fifth GU can-shaped magnetic core transformer (6e) and the synchronously rotating turntable (5) to rotate around the axis, thereby making the fifth GU can-shaped magnetic core transformer... The device (6e) rolls relative to the adsorption surface (14) of the straight adsorption strip (9). The end tape straight chord segment (4aa) adsorbed on the adsorption surface (14) of the straight adsorption strip (9) gradually wraps around the outer periphery of the fifth GU can-shaped magnetic core transformer (6e). When the telescopic rod (13) is completely retracted, the original end tape straight chord segment (4aa) is transformed into an insulating tape winding body (3) tightly wrapped around the waist of the fifth GU can-shaped magnetic core transformer (6e), and the straight adsorption strip (9) is completely separated from the fifth GU can-shaped magnetic core transformer (6e). Step 4: Control the rotating turntable (5) to rotate 60° clockwise, and the tape lead-out device adaptively leads out a taut tape (4); at this time, the original fifth GU can-shaped magnetic core transformer (6e) arrives at the loading and unloading area (30), and the original sixth GU can-shaped magnetic core transformer (6f) in the loading and unloading area (30) arrives at the position of the first GU can-shaped magnetic core transformer (6a) in the initial state; then the robot arm releases the clamping state of the already wrapped fifth GU can-shaped magnetic core transformer (6e) in the loading and unloading area (30) and takes it out for unloading, while the robot arm re-clamps a new unwrapped GU can-shaped magnetic core transformer (6) on the clamp (21) on the rotating seat (7) in the loading and unloading area (30); thus, one work cycle is completed, and the device is just restored to the "initial state".
