Description

Technical Field

[0001] This utility model relates to the field of current transformer manufacturing technology, specifically to an automatic circular sticker machine for current transformers. Background Technology

[0002] In the manufacturing of high-voltage instrument transformers, the wrapping of insulating paper is a core process for ensuring the insulation performance of the equipment. Currently, the wrapping of insulating paper is generally done manually: operators first arrange multiple strips of insulating paper in sequence, then fix the middle of each strip with tape to form a combined paper strip, then wrap it around the outer surface of the instrument transformer, and finally use additional tape for multiple layers of reinforcement. This wrapping process is relatively complex, time-consuming, and relies on skilled workers, which greatly increases production costs. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of complex wrapping process and high production cost in the prior art, so as to provide an automatic circular sticker machine for current transformers with high production efficiency.

[0004] Therefore, this utility model provides an automatic ring-shaped sticker machine for current transformers, comprising: a bracket, rotatably mounted on a support around the current transformer, the bracket having an insulating paper tape reel and a tape-pulling mechanism for feeding the insulating paper tape toward the tape-pressing mechanism, the insulating paper tape being coated with adhesive on the side facing the current transformer; a tape-pressing mechanism, disposed on the bracket, comprising two opposing rotating arms and tape-pressing members disposed at the front ends of the two rotating arms, the two rotating arms being able to open or close at a certain angle, and a notch being formed between the two tape-pressing members for the current transformer to move in or out, the tape-pressing mechanism having an initial position corresponding to when the current transformer is not moved in, and a tape-pressing position corresponding to when the current transformer is moved in, with the two rotating arms open at a certain angle; and a tape-cutting mechanism, disposed on the bracket, for cutting the wrapped insulating paper tape.

[0005] The pressing element is a roller.

[0006] The tape pulling mechanism includes: two tape clamps; a first cylinder assembly for driving the two tape clamps to clamp or release the free end of the insulating paper tape, and for driving the two tape clamps to move up and down.

[0007] The tape pulling mechanism also includes at least one guide wheel disposed between the insulating paper tape reel and the tape clamp.

[0008] The bracket is equipped with a gluing wheel for applying adhesive to the insulating paper tape.

[0009] The tape-cutting mechanism includes scissors and a second cylinder assembly for scissor action.

[0010] The pressing mechanism also includes a torsion spring for driving the rotating arm to reset.

[0011] The technical solution of this utility model has the following advantages:

[0012] 1. The automatic ring-shaped paper-sticking machine for current transformers provided by this utility model first clamps the insulating paper on the tape-pulling mechanism and pulls it between the current transformer and the tape-pressing mechanism. Then, the notches of the two tape-pressing parts are aligned with the edge of the current transformer and move towards the center of the current transformer. At the same time, the two tape-pressing parts can follow the movement of the opening and closing rotating arm, thereby pressing the adhesive-coated insulating paper tape onto the outer wall of the current transformer. Finally, the tape-cutting mechanism cuts the insulating paper tape. After the tape-pressing mechanism withdraws from the inside to the outside, it rotates around the center of the current transformer at a certain angle and continues to repeat the above tape-sticking action, thereby completing the wrapping of the insulating paper around the current transformer. Compared with the prior art, this achieves automated tape-sticking, greatly reducing labor costs and improving production efficiency.

[0013] 2. The automatic circular sticker machine for current transformers provided by this utility model uses rollers as the pressing component. When the rollers contact the insulating paper tape, they roll and rub against each other to avoid scratching the surface of the paper tape. The rollers also press linearly to ensure that the adhesive layer is tightly bonded to the surface of the current transformer.

[0014] 3. The automatic ring-shaped adhesive labeling machine for current transformers provided by this utility model solves the problem of reduced adhesion of the pre-coated adhesive layer due to aging or environmental factors by setting up an adhesive roller and replenishing the adhesive on-site.

[0025] Example

[0026] This embodiment provides an automatic circular sticker machine for current transformers, such as... Figure 1 As shown, it includes a support 3, a bracket 1, a belt pulling mechanism 16, a belt pressing mechanism 5, a belt cutting mechanism 17, and a robot arm 15.

[0027] Bracket 1 is rotatably mounted on support 3 around current transformer 2, such as... Figure 1 and Figure 3 As shown, the bracket 1 is provided with an insulating paper tape reel 4 and a tape pulling mechanism 16 for conveying the insulating paper tape 6 toward the tape pressing mechanism 5. The side of the insulating paper tape 6 facing the current transformer 2 is coated with adhesive.

[0028] Belt pulling mechanism 16, such as Figure 2 As shown, the device includes two clips 9, a first cylinder assembly 10, and a guide wheel 11. The first cylinder assembly 10 is used to drive the two clips 9 to clamp or release the free end of the insulating paper tape 6, and can also drive the two clips 9 to move up and down. It should be noted that the tape pulling mechanism 16 is equivalent to a robotic arm, which is a mature existing technology, so its specific structure and working principle will not be described in detail. In this embodiment, the guide wheel 11 is disposed between the insulating paper tape reel 4 and the clips 9. A gluing wheel 12 is provided between the guide wheel 11 and the insulating paper tape reel 4. The gluing wheel 12 is used to apply glue to the insulating paper tape 6. It should be noted that the insulating paper tape on the insulating paper tape reel 4 may not have glue on it; the glue is applied to the insulating paper tape by the gluing wheel 12.

[0029] The pressing mechanism 5 is mounted on the support 1, such as... Figure 2 , Figure 3 and Figure 4 As shown, it includes two opposing rotating arms 7 and a pressing element 8 located at the front end of the two rotating arms 7. The rotating arms 7 have an arc-shaped structure, and the two rotating arms 7 can open or close at a certain angle. A notch 18 is formed between the two pressing elements 8 for the current transformer 2 to move in or out. The pressing mechanism 5 has an initial position corresponding to the current transformer 2 not being moved in, and a pressing position corresponding to the current transformer 2 being moved in, with the two rotating arms 7 open at a certain angle. During the process of moving the current transformer 2 in, the two pressing elements 8 will contact the outer wall of the current transformer 2 and be forced to open the two rotating arms 7. In this way, the two pressing elements 8 move along the outer wall of the current transformer 2 and press the insulating paper tape 6 tightly onto the outer wall of the current transformer 2.

[0030] In this embodiment, the pressing element 8 is a roller, and the pressing mechanism 5 also includes a torsion spring (not shown in the figure) for driving the corresponding rotating arm 7 to reset.

[0031] The tape-cutting mechanism 17, mounted on the bracket 1, is used to cut the insulating paper tape 6 after the tape has been wrapped. Figure 2 As shown, the tape-cutting mechanism 17 includes scissors 13 and a second cylinder assembly 14 for the action of the scissors 13. It should be noted that the second cylinder assembly 14 is existing mature technology, therefore its specific structure and working principle will not be described in detail.

[0032] A robotic arm 15 is installed between the bracket 1 and the support 3. The robotic arm 15 can drive the bracket 1 to rotate around the current transformer 2 and can drive the bracket 1 to move towards or away from the current transformer 2. It should be noted that the robotic arm 15 is a mature existing technology, so its specific structure and working principle will not be described in detail.

[0033] The working principle of the automatic circular sticker machine for current transformers of this utility model is as follows:

[0034] During the tape application process, the two tape clamps 9 of the tape pulling mechanism 16 first clamp the free end of the insulating paper tape 6 and pull it downwards, thereby clamping and pulling the insulating paper tape 6 between the current transformer 2 and the tape pressing mechanism 5. During this process, the gluing roller 12 applies glue to the insulating paper tape 6. Then, the robot arm 15 drives the bracket to move towards the current transformer 2, and the notches 18 of the two tape pressing parts 8 align with the edge of the current transformer 2 and move towards the center of the current transformer 2. At the same time, the two tape pressing parts 8 can follow the movement of the openable and closeable rotating arm 7, thereby pressing the glued insulating paper tape 6 onto the outer wall of the current transformer 2. Finally, the tape cutting mechanism 17 cuts the insulation. Regarding the paper tape, it should be noted that after the pressing component 8 completes the pressing action on the main body of the insulating paper tape 6, the cutting mechanism 17 cuts off one end of the insulating paper tape 6, and the two tape clamps 9 release the other end of the insulating paper tape 6. Then, the pressing component 8 continues to press both ends of the insulating paper tape 6 onto the current transformer 2. After the current transformer 2 exits from the notch 18, the robot arm 15 bracket 1 rotates around the current transformer 2 at a certain angle and continues to repeat the above wrapping action, thereby completing the wrapping of the insulating paper tape on the current transformer. Compared with the existing technology, this achieves automated wrapping, greatly reducing labor costs and improving production efficiency.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
