The micro transformer needs to be dipped in paint during production.

[0003] In the prior art, the paint dipping device generally includes a paint dipping tank and a placing basket hung in the paint dipping tank. When dipping paint, the transformer is placed in the placing basket, and then the placing basket is immersed in the paint dipping tank so that the paint covers the transformer to realize paint dipping. However, the transformer is in a static state in the paint, and there is no flow wrapping effect between the paint and the transformer, which leads to uneven paint dipping of the transformer. SUMMARY

[0008] Preferably, connecting blocks are arranged on both sides of the placing basket, and the connecting blocks are slidingly connected with the top of the side plates of the corresponding paint dipping tank.

[0011] Preferably, the container is a closed cylinder, and the overflow hole is arranged on the outer peripheral wall of the container.

[0012] Preferably, the transfer mechanism is opposite to two, and the two ends of the container are provided with connecting shafts, and the two connecting shafts are coupled to the corresponding two ejection blocks.

[0013] Preferably, the bottom of the paint dipping tank is also configured with a plurality of independent and closed paint containing cavities, a pressing plate is slidably fitted in the paint containing cavity, an extrusion rod is arranged on the pressing plate and extends into the paint dipping tank and abuts against the corresponding cam, a return spring is connected to the pressing plate, the paint containing cavity is in pipeline communication with the paint dipping tank, and the paint containing cavity corresponds to the ejection blocks in the double-number positions in the axial direction of the transmission shaft; when the transmission shaft rotates, the cam can drive the ejection block to lift / drop, and the pressing plate also lifts / drops; when the pressing plate is pressed, the paint in the paint containing cavity is pressed into the paint dipping tank; when the pressing plate is lifted, the paint in the paint dipping tank is drawn back into the paint containing cavity.

[0018] 2. Through the rotation of the transmission shaft, the cam will drive the ejector block and the container to rise synchronously until the adjacent inclined surfaces are flush. The container will then drop and move horizontally under the guidance of the inclined surfaces. The transformer inside the container will not only move horizontally but also vertically, thereby ensuring a more uniform coating of the paint on the transformer.

After cooling, the ejector block drives the transformer down, and the pressure plate also descends. The paint in the paint chamber is pressed back into the paint immersion tank, and the transformer is re-immersed in the paint surface for a second dip. This invention allows the transformer to be dipped in paint while being moved, while also enabling multiple dips to further enhance the dipping effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0027] like Figures 1 to 5As shown, a transformer processing paint dipping device, comprising a paint dipping tank 1, a container 2 for accommodating a transformer to realize paint dipping operation is arranged in the paint dipping tank 1, and the container 2 is correspondingly configured with overflow holes 3 allowing paint to flow into and wrap the transformer. In addition, a moving mechanism 4 is arranged in the paint dipping tank 1, which is adapted to at least drive the container 2 to move horizontally in the paint dipping tank 1, so that the relative flow between the paint and the transformer is generated, that is, the paint will pass through the overflow holes 3 in a flowing manner and wrap the transformer, realizing more uniform paint dipping effect of the transformer.

[0028] In some embodiments, the container 2 comprises a placing basket 5, and the overflow holes 3 are arranged on the side wall and the bottom wall of the placing basket 5, thereby facilitating the flow of paint from the side and bottom to the side of the transformer, so that the transformer is less likely to have a paint dipping blind area. Specifically, the placing basket 5 is provided with connecting blocks 6 on both sides, and the connecting blocks 6 are slidingly connected with the top of the side plates of the corresponding paint dipping tank 1.

[0029] For example, the top of the side plate of the paint dipping tank 1 is provided with a guide rail, and the bottom surface of the connecting block 6 is correspondingly configured with a guide groove (not shown in the figure), and the horizontal movement of the placing basket 5 is realized by the adaptation of the guide rail and the guide groove. The moving mechanism 4 can preferably comprise a linear ejector or a transmission belt ejector, wherein the linear ejector can be a pneumatic cylinder, an electric cylinder or an oil cylinder, and the transmission belt ejector can be a transmission belt or a chain belt (not shown in the figure), and the horizontal movement of the placing basket 5 is realized by the ejection of the connecting block 6 by the moving mechanism 4.

[0030] In other embodiments, the moving mechanism 4 can comprise a mounting frame 7 and a transmission shaft 8 rotatably arranged on the mounting frame 7, for example, the transmission shaft 8 can be driven to rotate by a motor, and in a possible way, the transmission shaft 8 can also be manually rotated by hand. A plurality of ejection shafts 10 are movably arranged on the mounting frame 7 above the transmission shaft 8 in the vertical direction, and the plurality of ejection shafts 10 correspond to a plurality of cams 9 one by one. Specifically, the bottom end of the ejection shaft 10 abuts against the cam 9, for example, through a roller, and the top end of the ejection shaft 10 is provided with an ejection block 11, and the top of the ejection block 11 is configured with an inclined surface 12.

[0031] Referring to Figure 2 , the inclined directions of the plurality of inclined surfaces 12 are consistent, or can be described as the plurality of inclined surfaces 12 are arranged in the axial direction of the transmission shaft 8, and the container 2 is coupled on the ejection block 11. Among them, the word "coupled" means that the container 2 is placed on the ejection block 11 with the freedom of being guided to fall by the inclined surface 12.

[0032] For example, the plurality of ejection blocks 11 are arranged in sequence, and the lengths of the plurality of ejection shafts 10 are increased in sequence along the inclined direction of the inclined surface 12 (i.e. the direction consistent with the axial direction of the ejection shaft 10). Alternatively, the contour of the cam 9 can be designed such that the ejection heights of the plurality of ejection blocks 11 are increased in sequence. Of course, it is also possible that the lengths of the ejection shafts 10 are consistent, and the ejection heights of the plurality of ejection blocks 11 are substantially the same.

[0033] The point is that the contours of the plurality of cams 9 are adapted to drive the previous ejection block 11 to be lifted up while the next ejection block 11 is lowered. For example, the push contour of the adjacent cam 9 can be arranged symmetrically in the cross section. It can be imagined that when the corresponding ejection block 11 is lifted up by the push contour of the previous cam 9, the return contour of the next cam 9 is in abutment with the corresponding ejection shaft 10, so that the corresponding ejection block 11 is in a lowered state.

[0034] In a possible example, the container 2 is cylindrical or spherical, and the overflow hole 3 is arranged on the outer peripheral wall of the container 2. The inclined surface 12 is correspondingly configured with a groove for limiting the container 2 to fall along the axial direction of the transmission shaft 8 only, thereby preventing the container 2 from falling off the ejection block 11. The paint dipping device of the present disclosure can have the following use process:

[0035] First, for the convenience of description, the plurality of ejection blocks 11 will be defined as ejection block one, ejection block two, ejection block three, ejection block four, and so on in sequence along the axial direction of the transmission shaft 8.

[0036] S1, during the specific dipping, the container 2 loaded with the transformer is coupled to the ejection block one for dipping;

[0037] S2, after a threshold time, the transmission shaft 8 is controlled to rotate. At this time, the container 2 is in abutment with the ejection block two and does not move laterally, but is lifted up synchronously under the driving of the ejection block one. At the same time, the ejection block two is in a lowered state, and after the top of the ejection block one is flush with the top of the ejection block two, the container 2 will fall onto the ejection block two under the guidance of the inclined surface 12 of the ejection block one, so as to realize the lateral movement of the transformer in the paint.

[0038] S3, the transmission shaft 8 continues to rotate, and the ejection block two is re-ejected and lifts the container 2 to the ejection block three, similar to S2. At the same time, the ejection block one is lowered again, and another container 2 can be coupled to the ejection block two at this time. In this way, the containers 2 are moved laterally and lifted up step by step on the plurality of ejection blocks 11 in a continuous manner.

[0039] Referring to Figure 5In the example where the lifting heights of the ejection blocks 11 are sequentially increased, only the ejection blocks 11 in the front section can be dipped in the paint, and thus the containers 2 can be gradually moved laterally to the ejection blocks 11 not dipped in the paint for drying. The loading of the containers 2 on the ejection blocks can be achieved by a mechanical hand or a vibrating track loading plate, and can also be achieved manually. After the drying, the containers 2 can also be moved by a discharging mechanism.

[0040] Referring to Figure 4 As another solution, the ejection blocks 11 can also be not arranged in abutment, for example, fixed blocks 20 are arranged in abutment between the adjacent ejection blocks 11. It can also be understood that the fixed blocks 20 are ejection blocks 11 that do not move vertically. Correspondingly, the top of the fixed blocks 20 is also configured with a slope 12. Different from the abutment arrangement of the ejection blocks 11 described above, in the example, the fixed blocks 20 can be adapted not to be in the paint surface. Therefore, the paint dipping device of the present disclosure can also have the following use process:

[0041] First, along the axial direction of the transmission shaft 8, the ejection blocks 11 and the fixed blocks 20 can be arranged as ejection block one, fixed block 20 one, ejection block two, fixed block 20 two, and so on.

[0042] S1, during the specific dipping, the container 2 loaded with the transformer is coupled to the ejection block one for dipping;

[0043] S2, after the threshold time, the transmission shaft 8 is controlled to rotate. At this time, the container 2 abuts against the fixed block 20 one and does not move laterally, but is lifted synchronously under the driving of the ejection block one until the top of the ejection block one is flush with the top of the fixed block 20 two. Under the guidance of the slope 12 of the ejection block one, the container 2 will fall onto the fixed block 20 one, so as to realize the lateral movement of the transformer in the paint. And the container 2 abuts against the ejection block two and stays on the top of the fixed block 20, so that the transformer will be exposed to the paint surface for the first time for drying;

[0044] S3, the transmission shaft 8 continues to rotate, and the ejection block one and the ejection block two will descend again. During the descent, the tail end of the fixed block 20 one is flush with the front end of the ejection block two, and the container 2 in S2 falls onto the top of the ejection block two and descends into the paint for the second time for dipping;

[0045] S4, similarly to S2, the container 2 will be lifted and fall onto the fixed block 20 two for the second time for drying.

[0046] In this example, the pump device 21 can be fitted in the paint tank 1, and the paint can be added and extracted in the paint tank 1 by means of a centrifugal pump or the like. For example, before the container 2 is lifted to the fixed block 20, the paint surface will submerge the fixed block 20, and then during the process of dropping the container 2 to the fixed block 20, the container 2 is still moving laterally in the paint to achieve the flow wrapping of the paint and the container 2; after the container 2 is dropped to the fixed block 20, the pump device 21 extracts the paint in the paint tank 1, so that the transformer is separated from the paint surface for drying.

[0047] Referring to Figure 3 In another preferred example, the transfer mechanism 4 is provided with two opposite paint tanks 1, and the two ends of the container 2 are provided with connecting shafts 13, which are respectively coupled to the corresponding two ejection blocks 11. That is, in the case of loading the container 2 to the ejection block 1, the two connecting shafts 13 are respectively placed on the two ejection blocks 1.

[0048] For example, the inclined surface 12 is further provided with a toothed structure 18, and the connecting shaft 13 is provided with a gear 19 which is engaged with the toothed structure 18. When the container 2 is dropped under the guidance of the inclined surface 12, the gear 19 will drive the connecting shaft 13 and the container 2 to rotate under the action of the toothed structure 18, so that the transformer will be deflected to a certain extent in the container 2, rather than keeping a relatively static state with the container 2, so as to achieve a better paint dipping effect and reduce the paint dipping blind area. In this example, the reliability of the controllable rotation of the container 2 to prevent the occurrence of the paint dipping blind area is improved.

[0049] Referring to Figure 2 In some embodiments, the bottom of the paint tank 1 is further provided with a plurality of independent and closed paint containing cavities 14, and a pressing plate 15 is slidably fitted in the paint containing cavity 14, and the pressing plate 15 is provided with a pressing rod 16 which extends into the paint tank 1 and abuts against the corresponding cam 9. In addition, the pressing plate 15 is further connected with a return spring 17, and the paint containing cavity 14 is in communication with the paint tank 1 through a pipeline.

[0050] For example, the paint containing cavities 14 correspond to the ejection blocks 11 which are in the even positions along the axial direction of the transmission shaft 8. Therefore, the present disclosure can have the following use process:

[0051] The container 2 is placed on the ejection block 11 in the odd position (such as the ejection block 1) for paint dipping, and after a threshold time, the transmission shaft 8 rotates, the ejection block 11 in the odd position drives the container 2 to lift, at this time, the ejection block 11 in the even position (such as the ejection block 2) is lowered, and the pressing plate 15 also descends in the paint containing cavity 14 under the action of the cam 9, so as to press the paint in the paint containing cavity 14 into the paint tank 1, thereby maintaining the paint dipping state of the container 2;

[0052] During this period, the container 2 falls within the paint surface to the top of the ejector block 11 in the even position;

[0053] After the ejector block 11 in the odd position is lowered again, the ejector block 11 in the even position is raised again, at the same time the pressing plate 15 in the container 2 cavity is also raised again, so that the paint in the paint soaking groove 1 is drawn back to the paint container cavity 14, thus the transformer in the container 2 on the top of the ejector block 11 in the even position is exposed outside the paint surface for drying.

[0054] The above description is only the preferred embodiment of the present application, it should be understood that the present application is not limited to the form disclosed herein, should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein, by the above teaching or related art or knowledge.
