Description

Technical Field

[0001] This utility model relates to the field of transformer processing equipment, specifically to a four-way automatic winding and cutting integrated machine. Background Technology

[0002] Modern transformer manufacturing requires placing the coil on a base. The coil consists of two sets of coils wound on an iron core. Each set of coils has four copper wire pins. When assembling the coil with the base, the four copper wires need to be wound onto the pins of the base to complete the wiring. The operator places the wired product into the wire-pulling machine's product holder, steps on the foot pedal to start the wire-pulling machine, and pulls off the excess copper wire from the product.

[0003] The disadvantages of the above technology are: 1. Manually wrapping 4 copper wires around each of the 4 pins 1.5 times (the standard is 0.75 times), which is labor-intensive and inefficient; 2. The wire pulling machine uses clamps to hold the copper wire and then pulls off the excess copper wire. The copper wire often slips and cannot be pulled off or breaks in the middle, requiring rework and affecting efficiency. Third, multi-process operations result in wasted actions and manpower. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model proposes a four-directional automatic winding and cutting integrated machine; it combines the processes (winding and pulling wire into one), reducing wasted actions and streamlining operators; at the same time, the machine automatically winds wire, reducing labor intensity; and by changing the wire pulling to cutting wire, it achieves a 100% wire breakage rate and zero rework rate, thus improving efficiency.

[0005] To achieve the above objectives, the present invention provides a solution: a four-way automatic winding and cutting integrated machine, comprising a product table and a cutting mechanism, wherein the cutting mechanism is placed on the product table and the transformer base is placed on the cutting mechanism for cutting. The wire cutting mechanism includes a placement plate, fixed blades, and rotating blades. Multiple rotating blades are mounted on the placement plate, each rotating around the pin.

The blade surface of the fixed blade is in contact with the outer wall of the cutting blade.

[0007] Preferably, the top of the rotating blade contacts the bottom of the transformer base plate, and the height difference between the rotating cylinder and the base plate is greater than the diameter of the copper wire.

[0008] Preferably, the blade of the fixed blade is close to the root of the copper wire, wherein the fixed blade is inclined inward, and when the rotating blade and the fixed blade cut the copper wire, the rotating blade and the fixed blade form an acute angle.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, the four-way automatic winding and cutting machine includes a production table 1 and a cutting mechanism 2. The cutting mechanism 2 is placed on the production table 1, and the transformer base is placed on the cutting mechanism 2 for cutting. When working, the coil is placed on the base, and the four copper wire pins on the coil are wound around the inside of the pins of the base. Then the base and the coil are placed on the cutting mechanism 2, and the copper wire is wound around the pins by the cutting mechanism 2. The excess copper wire is cut off by the cutting mechanism 2.

[0023] The wire cutting mechanism 2 includes a placement plate 3, a fixed blade 4, and a rotating blade 5. The placement plate 3 is placed on the product table 1 and is bolted to the product table 1. The placement plate 3 has four through holes, and a rotating blade 5 is installed in each through hole. The rotating blade 5 rotates in the through hole, and each rotating blade 5 rotates around the PIN. The fixed blade 4 is fastened to the placement plate 3 around each rotating blade 5 by bolts. When the rotating blade 5 rotates, the rotating blade 5 drives the copper wire to wrap around the PIN. The rotating blade 5 cuts the copper wire by rotating and the fixed blade 4, thus realizing the integrated winding and cutting of the wire.

[0024] Furthermore, the rotating blade 5 includes a rotating cylinder 6 and a cutting blade 7. The rotating cylinder 6 is inserted into the through hole of the placement plate 3, and the outer wall of the rotating cylinder 6 is fitted with the inner wall of the through hole of the placement plate 3, thus realizing the rotation of the rotating cylinder 6. The top of each rotating cylinder 6 is fixed with an arc-shaped cutting blade 7 by welding. The cutting edge of the cutting blade 7 is close to the outer wall of the cutting blade 7. The cutting edge of the fixed blade 4 is fitted with the outer wall of the cutting blade 7. Each rotating cylinder 6 has a positioning hole 8 at its center for inserting a pin. During winding and cutting, the rotating cylinder 6... The base rotates around the PIN. When the PIN on the base is inserted into the rotating cylinder 6, the rotating cylinder 6 rotates. Since the cutting blade 7 is located at the top of the rotating cylinder 6, the cutting blade 7 rotates and drives the rotation around the PIN, thus winding the copper wire around the PIN. When the cutting blade 7 rotates to the position of the fixed blade 4, the cutting blade 7 and the fixed blade cut the copper wire. A rotating component 9 is provided at the bottom of the rotating cylinder 6 to drive the rotating cylinder 6 to rotate. The rotating component 9 drives the rotating cylinder 6 to rotate.

[0025] Furthermore, the top of the rotating blade 5 contacts the bottom of the transformer base plate, making it easier for the rotating blade 5 to push the copper wire around the PIN. The height difference between the rotating cylinder 6 and the base plate is greater than the diameter of the copper wire. When the copper wire is wound around the edge, the copper wire fits against the PIN. There is a support seat on the transformer base, which presses against the top of the placement plate 3. In this way, the bottom of the base is suspended, the PIN is inserted into the rotating cylinder 6, the bottom of the base contacts the top of the cutting blade 7, and the support seat of the base presses against the top surface of the placement plate 3. When the rotating blade 5 rotates, it winds the copper wire around the PIN.

[0026] Furthermore, the blade of the fixed blade 4 is close to the root of the copper wire. When the rotating blade 5 winds the copper wire, the rotating blade 5 rotates to the position of the fixed blade 4, and the rotating blade 5 and the fixed blade 4 cut the copper wire. When the blade of the fixed blade 4 is close to the root of the copper wire, the copper wire is wound around the PIN once (0.75 turns are acceptable). Several fixed blades 4 are tilted inward. When the rotating blade 5 and the fixed blade 4 cut the copper wire, the rotating blade 5 and the fixed blade 4 form an acute angle. Because the rotating blade 5 and the fixed blade 4 form an acute angle, when the rotating blade 5 rotates towards the fixed blade 4, the inclined surface of the fixed blade 4 presses the copper wire onto the PIN, so that the copper wire and the PIN are tightly attached.

[0027] Furthermore, the rotating assembly 9 consists of four transmission links 10. The top of each transmission link 10 is welded to the bottom of the corresponding rotating cylinder 6 and to two parts of the cross coupling. The transmission links 10 drive the rotating cylinder 6 to rotate. Each transmission link 10 has a transmission assembly 11 installed at its bottom to drive the transmission link 10 to rotate. The transmission assembly 11 is connected to the bottom of the transmission link 10 through the cross coupling. The transmission assembly 11 enables adjacent rotating cylinders 6 to rotate in opposite directions.

[0028] Furthermore, the transmission assembly 11 includes rotating gears 12, drive racks 13, and telescopic components 14. A rotating gear 12, which drives the transmission link 10 to rotate, is installed on each transmission link 10. Each rotating gear 12 is welded to two parts of a cross coupling via welding. The four rotating gears 12 are grouped in pairs. The two rotating gears on the right side mesh with each other, and a drive rack 13 is located to the right of the two right rotating gears 12. This drive rack 13 meshes with one of the right rotating gears 12, and the rotation of the two right rotating gears 12 is achieved by the forward and backward movement of the drive rack 13. The two rotating gears on the left side mesh with each other, and a drive rack 13 is located to the left of the two left rotating gears 12. This drive rack 13 meshes with one of the left rotating gears 12, and the rotation of the two left rotating gears 12 is achieved by the forward and backward movement of the drive rack 13. Telescopic components are provided between both sets of drive racks 13 and the worktable 1. 14. Each telescopic component 14 is a slide cylinder, and the telescopic components 14 are set on the left and right sides of multiple sets of rotating gears 12. The product table 1 has a cavity. The telescopic components 14, transmission components 11 and transmission connecting rods 10 are set in the cavity. The cylinder body of the telescopic component 14 is installed in the cavity of the product table 1 by bolts. The drive rack 13 is installed on two L-shaped plates by welding. The two L-shaped plates are installed on the top of the slide of the two telescopic components 14 by bolts. The two telescopic components 14 work synchronously. The two telescopic components 14 lift in opposite directions. The telescopic component 14 on the left lifts backward and the telescopic component 14 on the right lifts forward. In this way, the rotating cylinder 6 on the upper left of the placement plate 3 rotates clockwise, the rotating cylinder 6 on the lower left rotates counterclockwise, the rotating cylinder 6 on the upper right rotates counterclockwise, and the rotating cylinder 6 on the lower right rotates clockwise. In this way, the copper wire is wound around the PIN and the excess wire tail is cut off. After the transformer is taken out, the multiple rotating cylinders 6 rotate in the opposite direction to reset and perform the next winding and cutting operation.

[0029] Furthermore, a positioning component 15 is installed on the placement plate 3 by bolt fastening. The positioning component 15 consists of four limiting inclined blocks 16. The four limiting inclined blocks 16 are installed on the placement plate 3 by bolts. The limiting inclined blocks 16 are located around the transformer base and abut against the perimeter of the base. The top surface of the limiting inclined blocks 16 is inclined, which facilitates the positioning of the transformer on the placement plate 3 and ensures that the PIN is inserted into the rotating cylinder 6.

[0030] Furthermore, a lifting and lowering wire pressing mechanism 17 is provided above the product platform 1. The wire pressing mechanism 17 includes a coil pressing component 18 and a copper wire pressing component 19. A lifting component 21 is installed above the product platform 1 by bolts. The lifting component 21 is also a sliding cylinder. The sliding surface of the lifting component 21 is installed on the top of the product platform 1 by bolts. A lifting plate is installed on the outer wall of the cylinder of the lifting component 21 by bolts. The lifting component 21 realizes the lifting and lowering of the lifting plate. The coil pressing component 18 and the copper wire pressing component 19 are installed on the lifting plate of the lifting component 21 by bolts for lifting and lowering. When the lifting plate descends, the coil pressing component 18 and the copper wire pressing component 19 press the top of the transformer and the four copper wires respectively. Four copper wire pressing components 19 are arranged around the coil. The coil pressing components 18 press the top of the coil. The copper wire pressing components 19 press the four copper wires onto the placement plate 3. Each copper wire pressing component 19 is a pressing post, and each pressing post presses down on the four copper wires to prevent them from curling up. When the rotating blade 5 rotates, since the ends of the copper wires are in a pressed state, the copper wires are tightly attached to the pins when winding. The coil pressing components 18 are pressure blocks. Each pressing post and the bottom of the pressure block are fixed with a soft pad 20 by glue. The soft pad 20 is a rubber pad. The copper wire can be pulled under the soft pad 20 when pressed. This avoids the situation where the copper wire cannot be pulled out when pressed and cannot be wound. The soft pad 20 on the coil pressing components 18 plays a buffering role to prevent the coil from being crushed.
