Description

Technical Field

[0002] With the development of science and technology, the application of electronic equipment in production or life is becoming more and more extensive. The transformer is a basic electronic component used to change the voltage of alternating current. It is achieved through the principle of electromagnetic induction and plays a very important role in electrical equipment. The basic principle of the transformer is that it consists of two or more coils (windings), usually divided into main windings and secondary windings. The main winding is connected to the power supply, and the secondary winding is connected to the load. When alternating current is passed through the main winding, an alternating magnetic field is generated. This magnetic field is conducted to the secondary winding through the iron core, thereby inducing an electromotive force in the secondary winding, so that there is current on the load. During preparation, it is necessary to coat the transformer with copper wire wound on it, that is, to wrap the tape around the position where the copper wire is wound, so as to protect the winding of the transformer.

Example 1

[0032] See also Figure 1 A tape wheel comprises: a wheel body, the wheel body comprises an inner ring and an outer ring, and a plurality of elastic clamps 40 are distributed on the edge of the inner ring of the wheel body for clamping the inner ring side wall of the tape roll.

[0033] When installing the tape roll, just align the hollow part of the inner ring of the tape roll with the multiple elastic clips 40 and push them into place without wasting time on alignment. At the same time, the outer edges of the multiple elastic clips 40 abut against the inner ring side walls of the tape roll to clamp and fix them. Since the outer edges of the elastic clips 40 are compressed and deformed during installation, after the tape roll is installed, it will generate a resistance force on the inner ring side walls of the tape roll, so that the tape roll can be firmly fixed on the rubber disc and is not easy to deviate.

[0034] In this example, in order to better push the tape roll into place, the orientation of the plurality of elastic clips 40 is consistent with the central axis direction of the tape wheel 5 .

[0035] See also Figure 1 In this example, four elastic clips 40 are evenly distributed on the inner ring edge of the roulette body, and the elastic clips 40 are "U"-shaped. A mounting ring 41 is provided at the tail end of the "U"-shaped elastic clip, and a boss 42 engaged with the mounting ring 41 is provided on the surface of the roulette body. The elastic clips 40 are fixed on the boss 42 of the roulette body through the mounting ring 41.

[0036] The circular mounting ring 41 is matched with the cylindrical boss 42, so that the elastic clamp 40 can be stably fixed on the wheel body. When installing the tape roll, the top arc design of the "U" shape helps to guide the tape roll into place. At the same time, the outer side of the "U" shape will form an outward resistance force on the inner ring side wall of the tape roll after the tape roll is installed, making the installation of the tape roll more stable. In addition, the four elastic clamps 40 of this embodiment are distributed at 90 degrees on the inner ring edge of the tape wheel 5, which can evenly provide a clamping force on the four directions of the tape roll, making its clamping and fixing more stable and not easy to deviate.

[0037] In addition, the cooperation between the mounting ring 41 and the boss 42 facilitates the replacement of the elastic clamp 40. After being worn out during use, the elastic clamp 40 can be easily disassembled and replaced with a new one, thereby enhancing the convenience of production.

[0038] See also Figure 1 and Figure 2 In this embodiment, two tape reels 5 are symmetrically fixed on both sides of the vertical plate 3 through an arm, and a through hole is provided in the center of the tape reel 5. The tape reel 5 is installed at the mounting shaft 43 at the end of the arm of the rubber coating mechanism through the through hole, and the mounting shaft 43 is also sleeved with an adjustment spring 44. A threaded section is provided at the end of the mounting shaft 43 for screwing on a nut (not shown in the figure), and one end of the adjustment spring 44 abuts against the surface of the tape reel 5, and the other end abuts against the nut.

[0039] During installation, the tape wheel 5 is first sleeved on the mounting shaft 43 of the support arm through the through hole, and then the adjustment spring 44 is sleeved on the rear half of the mounting shaft 43, and then a nut is screwed on the end of the mounting shaft 43 to make the nut press the adjustment spring 44, and the installation is completed. In this way, the installation tightness of the tape wheel 5 can be adjusted by the compression effect of the screwing nut on the adjustment spring 44.

[0040] See also Figure 1-Figure 5 The present embodiment also provides a rubber coating mechanism, which is used for automatic rubber coating during transformer production, and comprises a base 1 and a bottom plate 2 arranged on the base 1, wherein the bottom plate 2 is provided with a vertical plate 3, and the vertical plate 3 is vertically arranged on the bottom plate 2, and two rubber coating conveying mechanisms are symmetrically arranged on both sides of the front of the vertical plate 3, and the glue outlets of the two rubber coating conveying mechanisms are arranged oppositely, and a clamping mechanism that can be horizontally moved for clamping the adhesive tape 4 is also provided between the glue outlets of the two rubber coating conveying mechanisms, and the clamping mechanism is used to move left and right to grab the adhesive tape 4 on both sides, and when the adhesive tape 4 of the rubber coating conveying mechanism on one side is used up, it can be moved to the rubber coating conveying mechanism on the other side to clamp the adhesive tape 4 to avoid stopping the operation;

[0041] The rubber lagging conveying mechanism includes the above-mentioned tape wheel 5, and a plurality of auxiliary rollers 6, a conveyor wheel 7, a tape pressing assembly, and a top pulley 8 which are sequentially arranged on the vertical plate 3 according to the tape conveying path;

[0042] A cutter 9 is also provided between the tape pressing assembly and the top belt wheel 8, and a glue outlet is located just above the cutter 9, so that the cutter 9 can cut the adhesive tape 4; the top belt wheel 8 and the cutter 9 are both arranged on the vertical plate 3 for movement in the vertical direction; the top belt wheel 8 is located just below the rubber-coated rotating shaft (not shown in the figure) of the transformer winding mechanism, so that when the rubber-coated rotating shaft is rubber-coating the transformer, the top belt wheel 8 can provide a supporting force to push the adhesive tape 4 toward the rubber-coated rotating shaft;

[0043] The movement direction of the clamp mechanism is perpendicular to the movement direction of the cutter 9 and there is an intersection, which makes it easy for the clamp mechanism to clamp the tape 4 and pull it out for rubber wrapping, while ensuring that the cutter 9 can stably cut the tape 4 when the rubber wrapping is completed.

[0044] During operation, the adhesive tape 4 is output from the adhesive tape wheel 5 and transmitted to the conveyor wheel 7 through multiple auxiliary rollers 6. The conveyor wheel 7 then conveys the adhesive tape to the tape pressing assembly. When the adhesive tape 4 reaches the tape pressing assembly, the clamping jaw 15 of the clamping jaw mechanism moves to the end of the adhesive tape 4 and clamps the end of the adhesive tape 4 and pulls it backward. When the adhesive tape 4 is pulled out to a sufficient distance, the above-mentioned tape pressing assembly presses the adhesive tape 4, and then pushes the adhesive tape 4 to the position of the rubber coating shaft through the above-mentioned top belt wheel 8. At this time, the clamping jaw 15 is released, the rubber coating shaft rotates and rubber coating is carried out, and the above-mentioned top belt wheel 8 returns to its original position. When the rubber coating is completed, the above-mentioned cutter 9 moves vertically upward to cut the adhesive tape 4, and then the tape pressing assembly is reset, completing a rubber coating process. After that, the clamping jaw 15 of the clamping jaw mechanism moves to the cut end of the adhesive tape 4 again to clamp, and the next rubber coating process is circulated.

[0045] See also Figure 2-Figure 4 In this embodiment, first slide rails 10 are respectively provided on the top of both sides of the base 1, and both sides of the bottom of the bottom plate 2 are slidably arranged on the first slide rails 10 through first sliders 11. Electric push rods 12 are respectively provided on both sides of the bottom of the base 1, and the ends of the push rods are connected to the first sliders 11 through first connecting blocks 13, which are used to drive the first sliders 11 to slide along the first slide rails 10, so as to drive the bottom plate 2 to move left and right. Since the base 1 and the bottom plate 2 are slidably connected through the slide rails, when the rubber coating device is stopped, the bottom plate 2 can be driven to move left and right through the electric push rods 12, and the mechanism on the bottom plate 2 can be slid as a whole to one end of the base 1, thereby avoiding space occupation and reducing the overall space size of the device.

[0046] In this embodiment, the rubber coating mechanism has two rubber coating conveying mechanisms symmetrically arranged on the vertical plate 3. When the adhesive tape 4 of the rubber coating conveying mechanism on one side is used up, the clamping claw mechanism can be moved to the rubber outlet of the rubber coating conveying mechanism on the other side to clamp the adhesive tape 4 and continue the rubber coating operation to avoid downtime. While simplifying the overall structure of the device, the production efficiency is effectively improved.

[0047] In addition, the above-mentioned two sets of rubber coating conveying mechanisms can work alternately, and the two sets of rubber coating conveying mechanisms can be used for rubber coating of transformers of different specifications. The tape reels 5 on both sides and the corresponding specifications of the tape 4 can be set according to the sizes and shapes of different transformers, so that the same set of equipment can be used for the process of alternating rubber coating of transformers of two different specifications, thereby improving the flexibility and adaptability of production.

[0048] See also Figure 2 In this example, the axial center position of the tape wheel 5 is slightly lower than the auxiliary roller 6 and much lower than the conveyor wheel 7, so that the tape roll is installed on the tape wheel 5 and maintains sufficient tension so that the tape 4 can be effectively transported to the conveyor wheel 7.

[0049] See also Figure 2 and Figure 3 Two proximity switches 14 are provided on both sides of the bottom of the base 1. The two proximity switches 14 are arranged one in front of the other, corresponding to the front and rear ends of the first slide rail 10 respectively. The first connecting block 13 is placed between the two proximity switches 14. When the electric push rod 12 drives the first slider 11 to move left and right through the first connecting block 13, the two proximity switches 14 are used to detect the limit position of its left and right movement. Through the above proximity switches 14, it is possible to prevent the first slider 11 from moving excessively and prevent damage caused by excessive impact force.

[0050] It should be noted that the electric push rod 12 can be replaced by other driving parts, such as stepper motors, servo motors, etc., to achieve precise position, speed and force control, making the left and right sliding of the base plate 2 more stable and reliable; and it can also be programmed as needed to achieve automated and serialized motion control, and can be flexibly adjusted and transformed according to different process requirements and work processes. In terms of motion, the position and strength of the motion can be accurately controlled, with good repeatability and stability, which improves the accuracy and stability of the rubber-coated component; in addition, no hydraulic or pneumatic components are required. Compared with cylinders, the maintenance cost of hydraulic systems or pneumatic systems is higher, and they have advantages in service life and maintenance, and have functions such as overload protection and limit protection, providing higher safety.

[0051] See also Figure 2-Figure 4 The clamping mechanism includes a clamping jaw 15 and a first cylinder 16 for driving the clamping jaw 15 to open and close to grab the adhesive tape 4. The vertical plate 3 is provided with a transmission mechanism for driving the clamping jaw mechanism to move horizontally on the back side away from the rubber bag conveying mechanism. The transmission mechanism includes a motor 17 fixed on the vertical plate 3, a gear arranged on the motor shaft, a rack 18 meshing with the gear, a second slider 19 fixed on the top of the rack 18, a second slide rail 20 on which the second slider 19 is slidably mounted, and a second connecting block 21 arranged on the top of the second slider 19, and the clamping mechanism is installed on the second connecting block 21.

[0052] When the clamping mechanism is moved horizontally left and right, the motor 17 drives the gear to rotate, and through the meshing action, the gear drives the rack 18 to move, and the rack 18 drives the second slider 19 to move left and right on the second slide rail 20, thereby enabling the clamping mechanism fixed on the second connecting block 21 to move. When the clamping mechanism moves into place, the first cylinder 16 is driven to control the opening and closing of the clamping jaw 15 to achieve the clamping of the tape 4.

[0053] See also Figure 3In this embodiment, in order to prevent the rack 18 from moving excessively, a limit plate 22 is provided at the bottom of one end of the rack 18, and a photoelectric switch 23 for sensing the position of the limit plate 22 is provided on the vertical plate 3. When the motor 17 drives the rack 18 to move through the gear, the position of the limit plate 22 can be used to limit the movement of the rack 18 through the photoelectric switch 23, so as to prevent the rack 18 from moving excessively and causing interference between the clamping mechanism and other components and causing damage.

[0054] See also Figure 2 and Figure 4 In this embodiment, two clamping blocks 24 are arranged opposite to each other at the clamping mouth of the clamping jaw 15. The length direction of the clamping block 24 is perpendicular to the length direction of the clamping jaw 15. Both ends of the clamping block 24 are provided with teeth. The teeth of the two clamping blocks 24 are engaged to clamp the adhesive tape 4. When the adhesive tape 4 needs to be engaged and pulled out, the clamping jaw 15 moves left and right under the drive of the rack 18. After it is in place, the first cylinder 16 drives the upper and lower clamping jaws 15 to engage, and the horizontally arranged clamping blocks 24 in the two clamping jaws 15 engage synchronously; at this time, since the two sides of the clamping block 24 are both opened and provided with teeth, when the clamping jaw 15 moves to the left, the left teeth of the two clamping blocks 24 engage, and the adhesive tape end at the adhesive outlet of the left adhesive tape conveying mechanism is clamped and pulled out; conversely, when the clamping jaw 15 moves to the right, the right teeth of the two clamping blocks 24 engage, and the adhesive tape end at the adhesive outlet of the right adhesive tape conveying mechanism is clamped and pulled out. The clamping jaws 15 of this structure can realize alternate clamping and pulling of the adhesive tapes 4 on both sides, so as to adapt to the process of alternately encapsulating transformers of two different specifications, thereby improving the flexibility and adaptability of production.

[0055] In addition, the meshing teeth provided at the clamping block 24 make the clamping block 24 more secure when clamping the tape 4, avoiding the problem of the tape falling off due to insufficient bite force of the clamping block 24, and further ensuring that the rubber encapsulation production can be carried out stably.

[0056] See also Figure 4 The belt pressing assembly includes a second cylinder 25 fixed on the vertical plate 3, a third slider 26 driven by the second cylinder 25 to vertically lift, a third slide rail 27 on which the third slider 26 is slidably mounted, and a pressure block 28 arranged on the top of the third slider 26, a pressure roller 29 is provided on the top of the pressure block 28, and the pressure roller 29 is installed on the vertical plate 3, and is used to cooperate with the pressure block 28 to press the tape 4.

[0057] When the adhesive tape 4 needs to be compressed, the telescopic shaft of the second cylinder 25 drives the third slider 26 to be vertically lifted and lowered on the third slide rail 27, so that the top pressure block 28 rises to the pressure roller 29 to compress the adhesive tape 4. When compressing, the adhesive tape 4 is between the pressure block 28 and the pressure roller 29. The surface of the pressure roller 29 can be coated with a soft coating to avoid compression damage to the adhesive tape 4. At the same time, the top surface of the pressure block 28 is adapted to the shape of the pressure roller 29 to enhance the fit and stability of the compressed adhesive tape 4.

[0058] See also Figure 2 and Figure 4 A third cylinder 30 is installed on the vertical plate 3, and the output shaft of the third cylinder 30 is connected to a fourth slider 31. The fourth slider 31 can be slidably set on a fourth slide rail 32 in a vertical manner, and the bottom end of the cutter 9 is fixed on one side of the fourth slider 31.

[0059] In this embodiment, when the cutter 9 is required to cut the adhesive tape 4, the third cylinder 30 drives the fourth slider 31 to vertically rise and fall along the fourth slide rail 32, so that the fourth slider 31 drives the cutter 9 to rise and cut the adhesive tape 4. In addition, the blade of the cutter 9 can be serrated; the serrated blade enables the cutter 9 to cut the adhesive tape more quickly and efficiently, and prevents the cutter 9 from being not sharp enough to cause the adhesive tape 4 to be deformed or fall off from the above-mentioned clamping jaws 15 when cutting the adhesive tape 4, thereby affecting the rubber coating.

[0060] Among them, in order to further save equipment space and simplify the structure, the third slide rail 27 and the fourth slide rail 32 can share the same long slide rail, the second cylinder 25 is suspended in the middle of the long slide rail through a mounting frame, and is connected to the third slider 26 through a telescopic shaft. The third slider 26 is set in the upper half of the long slide rail to realize the lifting and lowering of the pressure block 28, and the third cylinder 30 is fixed on the vertical plate 3, placed at the bottom of the long slide rail, and is connected to the fourth slider 31 through a telescopic shaft. The fourth slider 31 is set in the lower half of the long slide rail, and the cutter 9 is fixed on one side of the fourth slider 31 for lifting and lowering to avoid interference with the lifting and lowering of the pressure block 28. Here, in order to ensure that the sliding of the third slider 26 and the fourth slider 32 does not affect each other, it is necessary to ensure that the stroke of the pressure block 28 and the stroke of the cutter 9 are both lower than half the height of the long slide rail.

[0061] See also Figure 2 and Figure 4 A fourth cylinder 33 is installed on the vertical plate 3, and the output shaft of the fourth cylinder 33 is connected to the third connecting block 34. The third connecting block 34 is connected to the fifth slider 37 through a buffer structure. The fifth slider 37 can be vertically lifted and slidably set on the fifth slide rail 39, and the top pulley 8 is installed on the top of the fifth slider 37.

[0062] Among them, see Figure 5The buffer structure includes the plug rod 35, the sleeve 36 and the buffer spring 38. The plug rod 35 is fixed on the third connecting block 34. The plug rod 35 is covered with the sleeve 36. The top of the sleeve 36 is connected to the bottom of the fifth slider 37. The buffer spring 38 is sleeved on the outside of the sleeve 36, and one end is fixed on the third connecting block 34, and the other end is fixed on the bottom of the fifth slider 37. The buffer spring 38 allows the sleeve 36 to be extended and retracted up and down relative to the plug rod 35.

[0063] When the top pulley 8 needs to be raised or lowered, the third connecting block 34 is driven to rise by the fourth cylinder 33, and then the fifth slider 37 slides upward along the fifth slide rail 39, so that the top pulley 8 rises and pushes the tape 4 to the position of the rubber-wrapped shaft. When the top pulley 8 pushes the tape 4 to the rubber-wrapped shaft and contacts it, in order to reduce the indentation during rubber-wrapping, a buffer spring 38 is provided between the bottom of the fifth slider 37 and the third connecting plate 34 for buffering. The buffer spring 38 can provide a buffer force for the top pulley 8 when the rubber-wrapped shaft presses the rubber-wrapped shaft to indirectly contact the top pulley 8, so as to avoid the influence of the rigid force of the top pulley 8 when the rubber-wrapped shaft contacts the rubber-wrapped shaft on the rubber surface.

[0064] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
