Description

[0001] The utility model relates to the technical field of transformer production equipment, in particular to a rubber-coated assembly. Background Art

[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

[0033] See also Figure 1-Figure 5, the present embodiment provides a rubber-coated assembly, which is used for automatic rubber-coating during transformer production, and includes a base 1 and a bottom plate 2 arranged on the base 1, a vertical plate 3 is arranged on the bottom plate 2, and the vertical plate 3 is vertically arranged on the bottom plate 2, and two rubber-coated conveying mechanisms are symmetrically arranged on both sides of the front of the vertical plate 3, and the rubber outlets of the two rubber-coated conveying mechanisms are arranged oppositely, and a clamping mechanism that can be horizontally moved for clamping a tape 4 is also provided between the rubber outlets of the two rubber-coated conveying mechanisms, and the clamping mechanism is used to move left and right to grab the tapes 4 on both sides, and when the tape 4 of the rubber-coated conveying mechanism on one side is used up, it can be moved to the rubber-coated conveying mechanism on the other side to clamp the tape 4 to avoid stopping the operation;

[0034] The rubber-coated conveying mechanism includes a tape wheel 5 for installing the tape 4, and a plurality of auxiliary rollers 6, a sun gear 22, a belt conveyor wheel 7, a belt pressing assembly, and a top belt wheel 8 which are sequentially arranged on the vertical plate 3 according to the tape conveying path;

[0035] 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;

[0036] The movement direction of the clamp mechanism is perpendicular to the movement direction of the cutter 9, and there is an intersection, which is convenient 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;

[0037] The tape wheel 5 is equipped with a sensing device for detecting whether the tape roll is in place, and the sun gear 22 is equipped with a detector for detecting its rotational displacement; the sensing device and the detector are electrically connected to an external host computer (not shown in the figure).

[0038] During operation, the adhesive tape 4 is output from the adhesive tape wheel 5, and is transmitted to the central axis of the sun gear 22 through multiple auxiliary rollers 6, and then transmitted to the conveyor wheel 7. 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 completes the 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.

[0039] Among them, a sensing device for detecting whether the tape roll is installed in place is installed at the tape wheel 5. The sensing device is a pressure sensor (not shown in the figure). The pressure sensor is embedded and installed on the tape wheel 5, and its detection surface is placed on the surface of the tape wheel 5. The pressure sensor can detect whether the tape roll is installed on the tape wheel 5, and transmit the signal to the host computer. When the tape roll is used up, the host computer controls the equipment to stop to avoid the equipment running without glue. At the same time, this embodiment also sets a detector in the conveying path of the tape 4 to detect the rotation displacement of the sun gear 22 to measure the release length of the tape 4, and displays the output length of the tape 4 in the host computer, so that the producer can clearly understand the use of the tape 4.

[0040] See also Figure 1 and Figure 5 The detector includes a photoelectric switch 23. A plurality of notches 24 are formed evenly at intervals on the circumference of the sun wheel 22. The side of the sun wheel 22 is placed in the detection port of the photoelectric switch 23. The photoelectric switch 23 is arranged on the vertical plate 3. When the adhesive tape 4 is transmitted on the sun wheel 22, the adhesive tape 4 is transported forward under the pulling of the clamp mechanism, which can drive the sun wheel 22 to rotate, and then the photoelectric switch 23 measures the conveying length of the adhesive tape 4 by sensing the number of rotations of the notches 24 on the sun wheel 22; for example, when the number of sensings of the photoelectric switch 23 is the same as the total number of notches 24 of the sun wheel 22, it means that the sun wheel 22 has rotated one circle, indicating that the conveying length of the adhesive tape 4 is approximately the circumference of the central axis of the sun wheel 22.

[0041] In addition, the center axis of the sun gear 22 is arranged to have a height difference with the belt conveyor wheel 7, so that the center axis of the sun gear 22 is higher or lower than the center axis of the belt conveyor wheel 7. Through the height difference, the two are not in the same straight line, thereby increasing the tension of the tape 4.

[0042] In this embodiment, the host computer includes a PLC control screen. The host computer can also use a PC to control the display. The pressure sensor and the photoelectric switch 23 can communicate with the host computer in a wired or wireless manner.

[0043] See also Figure 1-Figure 3 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.

[0044] See also Figure 1 and Figure 3 In this embodiment, two rubber bag conveying mechanisms are symmetrically arranged on the vertical plate 3 of the rubber bag assembly. When the tape 4 of the rubber bag conveying mechanism on one side is used up, the clamping claw mechanism can be moved to the rubber outlet of the rubber bag conveying mechanism on the other side to clamp the tape 4 and continue the rubber bagging operation to avoid downtime. While simplifying the overall structure of the device, the production efficiency is effectively improved.

[0045] 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.

[0046] See also Figure 1 In this example, the two tape reels 5 are fixed on both sides of the vertical plate 3 by an arm respectively, and the axial position of the tape reel 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 reel 5 and maintains sufficient tension so that the tape 4 can be effectively transported to the conveyor wheel 7.

[0047] See also Figure 1 and Figure 2Two 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.

[0048] 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.

[0049] See also Figure 1-Figure 3 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.

[0050] 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.

[0051] See also Figure 1 and Figure 3In this embodiment, two clamping blocks are arranged opposite to each other at the clamping mouth of the clamping jaw 15, and the length direction of the clamping blocks is perpendicular to the length direction of the clamping jaw 15. Both ends of the clamping blocks are provided with teeth, and the teeth of the two clamping blocks 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 in the two clamping jaws 15 engage synchronously; at this time, since the two sides of the clamping block are opened and provided with teeth, when the clamping jaw 15 moves to the left, the left teeth of the two clamping blocks 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 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.

[0052] In addition, the meshing teeth arranged at the clamp block make the clamp block more secure when clamping the tape 4, avoiding the problem of the tape falling off due to insufficient bite force of the clamp block, and further ensuring that the rubber encapsulation production can be carried out stably.

[0053] See also Figure 3 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.

[0054] 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.

[0055] See also Figure 1 and Figure 3 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.

[0056] 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.

[0057] 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.

[0058] See also Figure 1 and Figure 3 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.

[0059] Among them, see Figure 4 The buffer structure includes the plug rod 35, the sleeve 36 and the 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 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 spring 38 allows the sleeve 36 to be extended and retracted up and down relative to the plug rod 35.

[0060] 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 spring 38 is provided between the bottom of the fifth slider 37 and the third connecting plate 34 for buffering. The spring 38 can provide a buffering force for the top pulley 8 when the rubber-wrapped shaft is pressed down and the rubber-wrapped shaft is indirectly in contact with 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.

[0061] 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.
