Description

Technical Field

[0001] This utility model relates to the field of coil winding machine technology, and in particular to a transformer coil winding machine. Background Technology

[0002] In the field of power and electronic equipment manufacturing, transformers, as the core component for power conversion, directly affect equipment performance and production efficiency through the automation and precision of their coil winding process. Traditional transformer coil winding machines suffer from low automation and excessive manual intervention. Operators need to frequently move iron core materials and manually adjust coil winding parameters, which not only results in high labor intensity but also easily leads to errors in the number of winding turns and the uniformity of wire arrangement due to human factors, reducing finished product quality and production efficiency. Furthermore, while some existing winding machines have automatic finished product straightening functions, the material conveying process still relies on manual assistance. Therefore, we have introduced a new transformer coil winding machine. Utility Model Content

[0003] The main objective of this invention is to provide a transformer coil winding machine that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A transformer coil winding machine includes a worktable. An operation panel is located on the right front side of the worktable. Two insertion holes are located on the front and rear left sides of the worktable. A feeding device is located on the left side of the worktable. A conveyor belt is located on the right front side of the upper end of the worktable. An electric mechanical gripper is located on the left front side of the upper end of the worktable. A robotic arm is located at the front center of the upper end of the worktable. A mounting frame is located at the rear center of the upper end of the worktable. An opening slot is located at the front end of the mounting frame. A feeding roller and a laser sensor are respectively located on the middle and right side of the inner rear wall of the opening slot. A limit plate is threadedly connected to the outer surface of the feeding roller. An electric telescopic rod is located on the middle of the inner rear wall of the mounting frame. A motor is located at the front end of the electric telescopic rod, and a mounting bracket is located at the output end of the motor.

[0005] Preferably, the feeding device includes a placement base, with casters at all four corners of the lower end of the placement base, two locking posts at the front right end and the rear right end of the placement base, a limit baffle fixedly installed at the front upper end of the placement base, a feeding slot at the rear left end of the placement base, a protective door movably installed at the rear left end of the placement base via a hinge, two magnetic suction blocks at the upper right end of the protective door, a push handle at the middle left end of the protective door and the front left end of the placement base, two magnetic suction holes at the upper left end of the placement base, and a feeding mechanism inside the feeding slot.

[0006] Preferably, the protective door is movably engaged inside the magnetic hole by a magnetic locking block.

[0007] By adopting the above technical solution, the magnetic card block and magnetic hole can be used to enable the rapid opening and closing of the protective door.

[0008] Preferably, the placement seat is movably engaged with the left end of the worktable via a locking pin and a socket, and the height of the placement seat is the same as the height of the worktable.

[0009] By adopting the above technical solution, the snap-fit ​​structure between the pin and the socket allows the placement seat to be quickly fixed on the left side of the workbench.

[0010] Preferably, the robotic arm corresponds to the position of the card holder, and the electric mechanical gripper corresponds to the position of the placement seat.

[0011] By adopting the above technical solutions: the robotic arm and the chuck are positioned to ensure that the robotic gripper can accurately align with the workpiece storage position, such as the workpiece on the chuck, to achieve rapid gripping; the electric robotic gripper is positioned to correspond with the placement seat to ensure that the workpiece is accurately placed in the designated location for storage.

[0012] Preferably, the feeding mechanism includes two first electric push rods. The output ends of the two first electric push rods are jointly provided with a placement plate. The upper end of the placement plate is provided with nine storage plates. The upper end of each of the nine storage plates is provided with several placement slots. The upper rear part of the placement base is provided with two vertical plates. The rear ends of the two vertical plates are inserted and fixedly installed with second electric push rods. The output ends of the two second electric push rods are provided with L-shaped push plates.

[0013] By adopting the above technical solution: two first electric push rods synchronously drive the placement plate to move up and down, which can sequentially transport the multi-layer storage plate to the designated height, realize the automatic supply of multiple batches of materials, reduce the frequency of manual loading, and the multiple placement slots of each storage plate can neatly arrange the workpieces for easy classification and management. The second electric push rod drives the L-shaped push plate to move forward, which can push the workpieces in the top layer of the storage plate to the designated position one by one.

[0014] Preferably, both L-shaped push plates are tightly fitted to the rear end of the uppermost storage plate, and both first electric push rods are fixedly installed on the inner lower wall of the discharge trough.

[0015] By adopting the above technical solution: the L-shaped pusher plate always fits the uppermost receiving plate, ensuring that the workpiece pushed each time is the material at the front of the current layer. The first electric push rod is installed on the lower wall inside the feeding slot, making the overall structure of the feeding mechanism compact and saving equipment space.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the design of the universal wheels and clamping column structure of the feeding device, the operator can quickly move and accurately position the placement seat, making it level with the workbench and seamlessly connected. With the feeding mechanism driven by the first and second electric push rods, the automatic lifting and lowering of the storage plate and the pushing of the workpiece are realized. There is no need for frequent manual handling of materials, which significantly reduces the labor intensity of the operator and improves the automation level and production efficiency of transformer coil winding. 2. The laser sensor monitors the starting position of the wire and the number of turns and tension during the winding process in real time. Combined with the precise coordination of the motor and electric telescopic rod, it ensures that the wire is evenly wound on the iron core. At the same time, the corresponding design of the electric mechanical claw and the placement seat allows the finished transformer to fall accurately into the placement slot of the storage plate, avoiding manual positioning errors, effectively improving the accuracy of coil winding and the consistency of finished products, and ensuring the quality stability of the transformer.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A transformer coil winding machine includes a workbench 1. An operation panel 2 is provided on the right front side of the workbench 1. Two insertion holes 3 are provided on the front and rear left sides of the workbench 1. A feeding device 4 is provided on the left side of the workbench 1. A conveyor belt 5 is provided on the right front side of the upper end of the workbench 1. An electric mechanical claw 6 is provided on the left front side of the upper end of the workbench 1. A robot arm 7 is provided on the front middle of the upper end of the workbench 1. A mounting frame 8 is provided on the rear middle of the upper end of the workbench 1. An opening slot 9 is provided on the front end of the mounting frame 8. A feeding roller 11 and a laser sensor 10 are respectively provided on the middle and right side of the inner rear wall of the opening slot 9. A limit plate 12 is threadedly connected to the outer surface of the feeding roller 11. An electric telescopic rod 13 is provided on the middle of the inner rear wall of the mounting frame 8. A motor 14 is provided on the front end of the electric telescopic rod 13. A card holder 15 is provided on the output end of the motor 14.

[0023] In this embodiment, the feeding device 4 includes a placement seat 40. Universal wheels 41 are provided at the four corners of the lower end of the placement seat 40. Two locking posts 42 are provided at the front and rear right ends of the placement seat 40. A limit baffle 43 is fixedly installed at the front upper end of the placement seat 40. A feeding slot 44 is provided at the rear left end of the placement seat 40. A protective door 45 is movably installed at the rear left end of the placement seat 40 via a hinge. Two magnetic blocks 47 are provided at the upper right end of the protective door 45. The middle left end of the protective door 45 is connected to the placement seat 40. Each of the left front ends of the seat 40 is equipped with a push handle 46. The upper left end of the seat 40 is equipped with two magnetic suction holes 48. The inside of the feeding slot 44 is equipped with a feeding mechanism 49. The protective door 45 is movably engaged with the inside of the magnetic suction hole 48 by a magnetic suction block 47. The seat 40 is movably engaged with the left end of the workbench 1 by a locking post 42 and a socket 3. The height of the seat 40 is the same as the height of the workbench 1. The position of the robotic arm 7 corresponds to that of the card holder 15, and the position of the electric robotic claw 6 corresponds to that of the seat 40.

[0024] Through the above scheme: the casters 41 at the lower end of the placement seat 40 allow it to move flexibly. It can be pushed to the left end of the workbench 1 by the push handle 46. The placement seat 40 is engaged with the insertion hole 3 of the workbench 1 by the locking post 42, which can achieve quick positioning and ensure consistent height, forming a smooth transition working surface. The protective door 45 is connected to the placement seat 40 by the hinge and can be opened outward. The magnetic block 47 is attracted to the magnetic hole 48, so that the protective door 45 fits tightly against the material feeding slot 44 to prevent the storage plate 492 from falling. The push handle 46 makes it convenient for operators to open and close the protective door 45, improving the ease of operation. The limiting baffle 43 at the upper end of the placement seat 40 prevents the storage plate 492 from sliding forward and ensures that the storage plate 492 is placed stably. The feeding mechanism 49 inside the material feeding slot 44 is responsible for the orderly supply of the storage plate 492.

[0025] In this embodiment, the feeding mechanism 49 includes two first electric push rods 490. The output ends of the two first electric push rods 490 are jointly provided with a placement plate 491. The upper end of the placement plate 491 is provided with nine storage plates 492. The upper end of each of the nine storage plates 492 is provided with several placement slots 493. The upper rear part of the placement seat 40 is provided with two vertical plates 494. The rear ends of the two vertical plates 494 are respectively inserted and fixedly installed with second electric push rods 495. The output ends of the two second electric push rods 495 are respectively provided with L-shaped push plates 496. The two L-shaped push plates 496 are tightly fitted with the rear end of the uppermost storage plate 492. The two first electric push rods 490 are respectively fixedly installed on the lower inner wall of the feeding slot 44.

[0026] The above scheme involves using a controller to open two first electric push rods 490, which synchronously drive the placement plate 491 to rise and fall, sequentially raising the multi-layer storage plates 492 to the height corresponding to the worktable 1. The placement slots 493 of each storage plate 492 are used to neatly arrange workpieces. When the uppermost storage plate 492 rises to the designated height, the L-shaped push plate 496 moves forward under the drive of the second electric push rod 495. As the second electric push rod 495 drives the L-shaped push plate 496 forward, it places the workpiece at the front end of the uppermost storage plate 492. Push the L-shaped pusher plate 496 to the edge of the placement seat 40 or the designated gripping position. After the push is completed, the L-shaped pusher plate 496 returns to its original position and waits for the next push command. The wound power transformer is pushed from the storage plate 492 to the front end of the placement seat 40. At this time, the storage plate 492 is located in the position where the electric mechanical claw 6 can grip and place it. The robotic arm 7 clamps one end of the external coil against the bottom side of the power transformer in the card holder 15. The electric mechanical claw 6 moves to the front end of the placement seat 40 and removes the wound power transformer and places it into the placement slot 493.

[0027] It should be noted that this utility model is a transformer coil winding machine. During use, the operator inputs processing parameters through the operation panel 2. The feeding device 4 moves to the left side of the worktable 1 via the casters 41. The clamping pin 42 is inserted into the insertion hole 3 to achieve precise positioning, ensuring that the placement seat 40 is level with the worktable 1. The protective door 45 is opened to stack the storage plate 492 on the placement plate 491. The protective door 45 is closed and locked. The first electric push rod 490 is activated, simultaneously lifting the placement plate 491 to the height where the first storage plate 492 is aligned with the electric mechanical claw 6. The second electric push rod 495 drives the L-shaped push plate 496 to move forward, pushing the uppermost storage plate 492 to the edge limit baffle 43 of the placement seat 40 to fit. After pushing is completed, the L-shaped push plate 496 retracts. The conveyor belt 5 places the iron core to be processed at the designated position on the worktable 1. The electric mechanical claw 6 moves to this position to clamp the iron core and place it on the clamping seat 15. Personnel input winding parameters through the operation panel 2. The feeding roller 11 is equipped with the wire coil. The laser sensor 10 monitors the starting position of the wire in real time to ensure winding accuracy. The robot arm 7 pulls the wire from the feeding roller 11 and sends the wire end through the opening slot 9 to the clamping seat 15, where it is clamped and fixed on one side of the bottom end of the iron core. The motor 14 drives the clamping seat 15 to rotate, while the electric telescopic rod 13 controls the motor 14 to move back and forth, so as to achieve uniform winding of the wire on the iron core. The laser sensor 10 continuously detects the number of winding turns and the wire tension. After the set parameters are reached, the motor 14 and the electric telescopic rod 13 stop moving, completing the winding of a single coil. After winding, the electric mechanical claw 6 moves to the clamping seat 15, picks up the finished transformer, and transfers it to the placement slot 493 at the front end of the placement seat 40. At this time, the controller starts the first electric push rod 490. Repeating the feeding operation can push the empty storage plate 492 back to fit with the limit baffle 43.
