Description

Technical Field

[0001] This utility model relates to the field of transformer electrode coating technology, and in particular to a transformer electrode coating device. Background Technology

[0002] In electrode coating processes, dip coating is more suitable for coating small electrodes, and it has the advantages of simple operation, high production efficiency, and low paint loss. It is widely used in the batch coating of small transformer electrodes. The electrodes of small transformers are usually arranged at one end of the winding frame. Due to structural requirements, some transformer winding frames have other protruding structures formed on the end face where the electrodes are located. This means that when the electrodes need to be completely immersed in the paint during electrode coating, it is easy to dip-coat other uncoated protruding parts as well. This not only easily leads to paint waste, but also affects the overall aesthetics of the transformer. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a transformer electrode coating device that can ensure the quality and efficiency of electrode coating while avoiding contact between other parts of the transformer and the slurry during the immersion coating of transformer electrodes.

[0004] Technical solution: To achieve the above objectives, the present invention provides a transformer electrode coating device, which includes a fixing component capable of clamping and fixing the transformer, and ensuring that the electrode end face of the transformer faces downward.

[0005] The fixing member is connected to the lower part of the lifting member through the swing member. When the lifting member descends, the electrode can be inserted into the slurry. When the swing member swings upward, when most of the electrode is in the slurry, the other protruding structures on the end face of the electrode are all above the slurry surface.

[0006] The lifting component can move horizontally, causing the electrode to exert a thrust on the slurry on the side of its surface that is more exposed above the liquid surface.

[0007] Furthermore, when the fixing member fixes the transformer, the plurality of electrodes on the transformer are arranged horizontally, and the arrangement direction is perpendicular to the swing surface of the swing member.

[0008] Furthermore, the fixing member clamps and fixes several transformers, and the arrangement direction of the multiple transformers is consistent with the arrangement direction of the multiple electrodes.

[0009] Furthermore, a toggle plate is provided between two adjacent electrodes. The toggle plate is in contact with the end face of the electrode, and a gap is left between the toggle plate and the electrodes on both sides. The lower edge of the toggle plate is immersed in the slurry.

[0010] Furthermore, the fixing member includes a groove with a receiving groove. The bottom surface of the receiving groove forms a supporting force on the installed transformer, and the surrounding groove surfaces form a ring-shaped constraint force on the installed transformer. The cover plate can be adsorbed and fixed at the opening of the receiving groove to press the transformer into the receiving groove.

[0011] Furthermore, the fixing member and the swing member are connected separately. The swing member adopts a clamping mechanism, which is hinged to the lower part of the lifting member and driven to swing by a driving device.

[0012] Furthermore, the cover plate and the groove are connected separately, and the swing member clamps and fixes the groove.

[0013] Furthermore, the cover plate is magnetically attracted and fixed to the groove end face of the groove component.

[0014] Beneficial Effects: This utility model discloses a transformer electrode coating device that, through angle adjustment, allows the electrodes to be inserted as much as possible into the slurry while ensuring that other parts of the transformer do not come into contact with the slurry. Then, by lateral movement, the slurry is pushed upwards to achieve recoating of the parts above the liquid surface, thus ensuring the coating quality of the electrodes and not affecting the overall aesthetics of the transformer. Furthermore, in the simultaneous coating of multiple transformers, it ensures that multiple electrodes on each transformer receive good coating quality. By measuring the height of the electrodes above the slurry surface, the coating action is controlled, ensuring that this high coating quality is consistently maintained during long-term coating operations. Attached Figure Description

[0016] Figure 2 for Figure 1 A magnified view of a portion of point a. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] As attached Figure 1-2 The transformer electrode coating device includes a fixing member 1, which clamps and fixes a transformer 2, ensuring that the end face of the transformer 2 with electrode 21 faces downwards. The fixing member 1 is connected to the lower part of a lifting member 4 via a swing member 3. When the lifting member 4 descends, it allows the electrode 21 to be inserted into the slurry 5. When the swing member 3 swings upwards, it ensures that when most of the electrode 21 is within the slurry 5, all other protruding structures 22 on the end face of the electrode 21 are above the surface of the slurry 5. The lifting member 4 can move horizontally, causing the electrode 21 to exert a pushing force on the side of the slurry 5 that is more exposed above the liquid surface.

[0019] This solution is primarily applied to electrode coating operations when there are other interfering structures on the transformer end face that could affect electrode dip coating. Firstly, considering production efficiency and paint loss, a dip coating process is chosen. The transformer is clamped and fixed with the electrodes facing downwards, facilitating the insertion of the electrodes into the paint slurry. To avoid paint loss and waste caused by immersing un-coated structures in the slurry, this solution uses a swinging component to adjust the transformer's angle and orientation. This raises the side with other protruding structures on its bottom surface relatively, while lowering the side containing the electrodes. This ensures that while unrelated structures are not immersed in the slurry, most of the electrodes are submerged, with only a small portion near the root above the liquid surface. Then, by horizontally moving the transformer, the electrodes, tilted and inserted into the slurry, slide a certain distance within the slurry. During this sliding, the electrodes exert a pushing force on the slurry in front of them. The pushed-up slurry climbs up the electrode surface and flows to both sides along the arc surface, converging on the back side of the electrode. This covers the un-immersed portion of the electrode with slurry, thus completing the coating of the entire electrode. This ensures the quality of the electrode coating and avoids dip coating on other un-coated parts of the transformer. In the long run, this reduces the loss and waste of slurry.

[0020] When the fixing member 1 fixes the transformer 2, the multiple electrodes 21 on the transformer 2 are arranged horizontally, and the arrangement direction is perpendicular to the swing surface of the swing member 3. After the swing member adjusts its posture, it can ensure that the multiple electrodes maintain the same height and angle relationship with the liquid surface. After the slurry is inserted, the parts exposed above the liquid surface are also roughly the same, and most of them are located on the same side. This makes the recoating effect of each electrode consistent after horizontal sliding, thereby ensuring the coating quality of each electrode.

[0021] The fixing member 1 clamps and fixes several transformers 2, and the arrangement direction of the multiple transformers 2 is consistent with the arrangement direction of the multiple electrodes 21. This allows for simultaneous dip coating of multiple electrodes on multiple transformers, further improving coating efficiency while ensuring the coating quality of each electrode.

[0022] A toggle plate 6 is provided between two adjacent electrodes 21. The toggle plate 6 is in contact with the end face of the electrode 21, and a gap is left between the toggle plate 6 and the electrodes 21 on both sides. During impregnation, the toggle plate 6 can provide support for the lower end face of the transformer and achieve a limiting function, as shown in the attached figure. Figure 1As shown, when most of the electrode is in the slurry, the lower edge of the agitator 6 is immersed in the slurry 5. Therefore, during the lateral sliding of the slurry for recoating, the agitator can push more slurry in the forward direction. The increased liquid flow due to the agitation will split to both sides of the agitator, creating a gradually decreasing liquid flow on both sides. The gap between the agitator and the electrode ensures that the electrodes on both sides are positioned within the liquid flow during movement, thus achieving recoating of the portion of the electrode above the liquid surface. By setting the width of the agitator and adjusting the moving speed, the height of the liquid flow on both sides can be controlled, thereby ensuring a full-coverage coating effect.

[0023] Example: The fixing component 1 includes a groove 11 with a receiving groove. The bottom surface of the receiving groove provides support for the installed transformer 2, and the surrounding groove surfaces provide annular constraint force for the installed transformer 2. The cover plate 12 can be adsorbed and fixed at the opening of the receiving groove to press the transformer 2 into the receiving groove. This can firmly clamp and fix the transformer, preventing the transformer from shifting or shaking during the coating process and affecting the coating quality.

[0024] The fixed component 1 and the swing component 3 are connected separately. The swing component 3 employs a clamping mechanism, which is hinged to the lower part of the lifting component 4 and driven by a drive device. The clamping mechanism uses existing automated mechanical grippers. The lifting component 4 can be controlled by a robotic arm or a spatial coordinate displacement mechanism, while the mechanical grippers control the swing angle via a motor or other drive device. Considering the time-consuming loading and unloading process of multiple transformers during simultaneous coating operations, the separate connection allows the installation and unloading of transformers relative to the fixed component to be independent of the coating process, enabling simultaneous operation and further improving the efficiency of batch coating. When coating the transformer electrodes, the coating process is completed by clamping the fixed component 1, on which the transformer is mounted, with the mechanical grippers.

[0025] The fixing component 1 is provided with a limiting slot that is compatible with the mechanical gripper, which ensures that the gripping position is consistent each time, thereby ensuring the coating quality of each electrode in accordance with the above principle while ensuring efficiency improvement.

[0026] The cover plate 12 and the groove 11 are connected separately, and the swing member 3 clamps and fixes the groove 11. Since the cover plate 12 only serves to fix the transformer during the coating process and has no function during the loading and unloading of the transformer, in practical applications, the cover plate 12 can be used as a common component, while two grooves 11 are provided, which are used alternately for coating and synchronous loading and unloading, and the cover plate is always attached to the groove 11 that is currently being coated.

[0027] Preferably, the cover plate 12 is magnetically attracted and fixed to the groove end face of the groove member 11, which makes it more convenient and quick to use and can further improve efficiency.

[0028] A photoelectric sensor 31 is provided on one side of the swinging component 3. The photoelectric sensor 31 is electrically connected to the controller, which is used to control the descent height of the lifting component 4 and the swing angle of the swinging component 3. In the initial state, the electrode is in a vertically downward state. Before the lifting component 4 descends, the swinging component 3 first swings upward to adjust the angle at which the electrode is inserted into the slurry. During the swinging process of the swinging component 3, when the infrared light of the photoelectric sensor 31 is perpendicular to the liquid surface, the swinging component 3 swings to the preset angle. Then, the relative height to the liquid surface is detected by the photoelectric sensor 31 to control the descent height. Since the liquid level of the slurry will drop as the coating progresses, in order to ensure that the part of the electrode exposed on the liquid surface is approximately the same for each batch without causing excessive coating, this ensures that the recoating effect produced under the same movement parameters is consistent and optimal, thereby ensuring the continuity and stability of this beneficial effect in long-term coating operations.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
